Description

Method, user terminal and node for determining a cell Technical field

The embodiments of the present invention relate to the field of mobile communications, and in particular, to a method, a user terminal, and a node for determining a cell.

Background technique

A new network deployment is gradually being introduced into next-generation wireless networks, namely heterogeneous network (HetNet) deployments. In HetNet, some low-power nodes are deployed in the coverage of the Macro Cell, which can be a Radio Radio Head (RRH) or a small base station (Pico). One or more of eNB), home base station, relay node (RN), and WLAN access point. The cells of these low-power nodes can be compared because the coverage is smaller than that of the macro cell. It is called a small cell. Among them, the macro cell can provide seamless coverage for users, and these small cells can increase the capacity of the system. In actual deployment, the macro cell and the small cell may use the same frequency or different frequencies. The network in which the macro base station and the micro base station coexist is a heterogeneous network.

Both the macro base station and the micro base station can serve the user equipment (User Equipment, UE). The cell of the macro node is generally referred to as a macro cell, and the cell of the micro node is generally referred to as a micro cell. When the UE in the idle state resides in a certain When the network is in the cell of the node, the network sends a paging message to the UE in order to page the UE to notify the UE that there is a service or notify the UE to establish a connection transmission service, and all the micro base stations and macro base stations included in the entire tracking area send a paging message to the UE. However, the UE will only receive paging messages in the cell in which it camps. A large number of micro base stations exist in a heterogeneous network, and all base stations (including a macro base station and a micro base station) in the entire tracking area (TA) send paging messages to page the UE, so that the air interface sends a large number of messages. This in turn causes waste of resources and increases network load. Therefore, how to avoid the problem that a large number of base stations send paging messages to the UE in a heterogeneous network, causing air interface signaling storms and resource waste, is a problem to be solved by the present invention.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of a method for determining a cell according to a first embodiment of the present invention. The method is applicable to a scenario in which a user terminal determines a cell that transmits a data service, where an execution entity of the method is User terminal, the specific process of the method includes:

S101: The UE camps on the first cell.

Specifically, the purpose of the paging message may specifically be one or more of the following: In the first case, the paging information is transmitted to the idle UE (to transmit paging information to a UE in RRC_IDLE). For example, the paging message can be used to ping the UE when the service is available, and the UE can establish a Radio Resource Control (RRC) connection, progress service transmission with the base station, or network locating when the UE receives the paging message. The UE, for example, the Mobility Management Entity (MME) sends a paging message to the base station, and the UE that sends the paging message by the subsequent base station is used to notify the UE of the service or notify the UE to change from the idle state to the connected state.

In the second case, in order to notify the UE that the UE is in the RRC_IDED and UEs in RRC_CONNECTED about a system information change, the paging message is used to notify the UE that the cell is sent by the paging message. The system message of the node is updated. When the UE receives the paging message for indicating the system message update, the UE re-acquires all the system messages and re-receives all system messages (When the Paging message indicates system information changes then UE shall re-acquire all system information).

The third case is to inform the UE of the Earthquake and Tsunami Warning System (ETWS) first notification and/or the ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification). That is, the paging message is used to notify the UE of the earthquake tsunami system ETWS first notification and/or the ETWS second notification caused by the paging message.

The fourth case is to inform the UE of the commercial mobile alert service notification (to inform about a CMAS notification), that is, the paging message is used to inform the UE of the Commercial Mobile Alert Service (CMAS).

In the first case, when the paging message can be used for the service, the network pages the UE. When the UE receives the paging message, the RRC connection can be established, and the base station performs the service transmission. In this case, since the base station in the entire TA area sends a paging message, the air interface signaling load is relatively large. In the second case or the third case or the fourth case, for example, when the paging message is used to notify the UE that the system message of the cell that sent the paging message is changed, the UE may be instructed to receive the system message or update. system information. And paging the second case in the base station or the cell itself Since the system message update causes the base station to send a paging message in a cell for notifying the cell system to update the message, this situation does not cause too much air interface signaling load. Therefore, in order to reduce resource consumption, the UE is camped on The first cell receives the paging message listed in the first case, and the other cell (for example, the micro cell) does not transmit the paging message exemplified in the first case.

Optionally, the UE is still camped on the first cell in the process of determining the second cell or after determining the second cell according to the indication message; or the UE is determining the second cell. During or after the process, the UE performs cell reselection of the first cell.

Further, the UE receives a paging message only from the first cell; or the UE receives a paging message in the first cell, and the UE receives a paging message in the second cell, Receiving, by the UE, the paging message in the second cell includes at least one of: a paging message for notifying the second system message update of the second cell; and notifying the first about the earthquake tsunami system ETWS A paging message for notification and/or ETWS second notification; a paging message for informing the commercial mobile alert service CMAS to notify.

First, the “the UE receives the paging message only from the first cell” may be understood as: for the first cell (or the new cell after the first cell reselection is performed by the UE in the first cell) a first cell) and a second cell (or the UE reselects the determined new second cell when the second cell performs the second cell reselection), and the UE only performs from the first cell (or the UE performs in the first cell) When the first cell is reselected, the newly selected first cell after reselection receives the paging message, and does not reselect the new cell from the second cell (or when the UE performs the second cell reselection in the second cell) The second cell) receives any paging message. The UE receives the paging message (the UE selects and monitors the indicated paging channels of the cell), and the paging message is used for at least one of the following:

A) used to transmit paging information to the UE (to transmit paging information to a UE).

B) used to notify the UE that the first system message of the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) is used to inform the UE of the CMAS notification (to inform about a CMAS notification).

Specifically, the present invention recommends that the paging message is used to transmit paging information to the UE (to Transmitting paging information to a UE), optionally, the paging message may also be used for one or more of the other three (B/C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation.

Second, the UE receives a paging message in the first cell, and the UE receives a paging message in the second cell, and the UE receiving the paging message in the second cell includes the following At least one: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial The paging message notified by the mobile alert service CMAS. The message may be: the UE receives the paging message (which may be UE selects and monitors the indicated paging channels of the cell), and the paging message is used for the following At least one of:

A) for transmitting paging information to the UE (to transmit paging information to a UE).

B) The first system message used to notify the UE that the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS Notification (Commercial Mobile Alert Service, CMAS).

Specifically, the present invention recommends that the paging message is used to transmit paging information to the UE (to transmit paging information to a UE). Optionally, the paging message may also be used in other three types (B/ One or more of C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation.

In addition, on the basis of the foregoing, in the second cell, the UE may receive a paging message in the second cell, and the UE receiving the paging message in the second cell includes at least one of the following: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial mobile alarm service CMAS notification Paging message.

The above four types (one or more of the ABCDs) may be implemented in the same paging message, or may be implemented in multiple paging messages, and the present invention does not limit the specific content included in the specific paging message, but only Describe the paging message received by the UE in the second cell, and the paging message may be used for which purpose or for which purpose. This paragraph can also be applied to other embodiments. Do not repeat them one by one.

In the present invention, the first cell is a cell of the first node, and the second cell is a cell of the second node. The first node may be a macro base station, such as a Macro eNB; the second node may be a micro base station, such as a Pico eNB, HeNB, Small Cell eNB, Relay Station, and the like. Of course, in the present invention, the node may be various types of base stations and nodes, for example, a Macro eNB, a Micro eNB, a Pico eNB, a HeNB, a Small Cell eNB, a Relay Station, etc., and possibly a network node such as a mobility management entity MME. There are no restrictions here.

S102: The UE receives the indication message sent by the first node corresponding to the first cell.

Optionally, the indication message is a first system message of the first cell, where the first system message includes configuration information of a candidate cell, where the configuration information of the candidate cell includes at least one of: a candidate cell The system to which it belongs, the frequency used by the candidate cell, the priority of the frequency, the physical cell ID (PCI), the priority of the system to which the cell belongs, the identifier of the non-pending broadcast, the minimum access level of the cell Qrxlevmin, the minimum The offset value Qrxlevminoffset of the access level value, the compensation amount Pcompensation of the threshold, the received power Qqualmeas of the cell measured by the UE, the minimum required quality level value Qqualmin of the cell, the offset value Qqualminoffset of the minimum required quality level value of the cell, time Treselection, a parameter QHyst for controlling the sorting hysteresis, an offset Qoffset used between the serving cell and the neighbor cell when having the same priority frequency, an identifier of the candidate cell; and/or the first system message includes sending a page The sending, the paging identifier is used to indicate that the first cell can send a paging message to the UE

For example, for a certain system (for example, in the system EUTRA), maxFreq frequencies or frequencies used by maxFreq cells are provided. The following is exemplified by frequency. For each frequency carrierFreq, there is a corresponding cell reselection priority cell Reselection. Priority. The physical cell of the cell corresponding to each frequency identifies the PCI. In addition, the cell that does not send the paging message may be used as a class to provide the configuration of the cell (the configuration is as shown in the configuration information in step S102), so that the cell may have one in the message. The identifier of the page to be sent, for example, no_paging_cell(s), etc., is not limited in the present invention. Thereby the UE can select and determine a suitable cell, ie the second cell, in such a cell.

FreqPriorityListEUTRA::=SEQUENCE(SIZE(1..maxFreq))OF FreqPriorityEUTRA;

FreqPriorityEUTRA::=SEQUENCE{

carrierFreq ARFCN-ValueEUTRA,

cellReselectionPriority CellReselectionPriority

The configuration information of the candidate cells of the multiple systems, such as GERAN, EUTRA, UTRA-FDD, and UTRA-FDD, may be provided in the configuration message, and is not illustrated here.

The configuration information also provides a configuration for cell selection or cell reselection, such as the S criteria or the parameters required in the R criteria used in cell selection. The S criteria for cell selection, including:

Srxlev>0 AND Squal>0;

Where 1) Srxlev = Qrxlevmeas - (Qrxlevmin + Qrxlevminoffset) - Pcompensation;

Srxlev is the cell selection reception level value, and Qrxlevmeas is the received power of the cell measured by the UE. The parameters provided in the message: the minimum access level Qrxlevmin of the cell, the offset value Qrxlevminoffset of the minimum access level value, and the compensation amount Pcompensation of the threshold. Therefore, according to the above equation, the parameters configured in the message, and rxlevmeas, that is, the received power of the cell measured by the UE, can calculate whether Srxlev is greater than zero.

2) Squal=Qqualmeas–(Qqualmin+Qqualminoffset);

Similarly, Squal can be calculated.

Intra-frequency and equal priority inter-frequency cell reselection criteria, also called R-criteria, includes: generating sequence values Rs and Rn for the serving cell and the neighbor cell, respectively. . As long as the neighbor cell is ranked higher than the neighbor cell in the Treselection time, the UE will reselect the high order candidate cell.

R _S =Q _mean,s +Q _Hyst ;

R _n =Q _mean,n +Qoffset;

Where:

The indication message may be the first system message of the first cell, or may be other messages, which are not limited in the present invention.

S103: The UE determines the second cell according to the indication message.

Specifically, the indication message is a first system message of the first cell, and the first system message includes configuration information of a candidate cell, and the UE determines the second cell according to the first system message, specifically including The UE determines the second cell according to the configuration information of the candidate cell. For example, the configuration information of the candidate cell includes the frequency used by the candidate cell, the priority of the frequency, and the UE measures the frequency used by the candidate cell, determines the signal quality of the candidate cell according to the measurement result, and then, according to the signal quality and/or frequency, the UE The priority determines the second cell. Here, the candidate cell is a set of cells. If the priorities of the frequencies of the two cells are the same, the UE may be the second cell according to the determined signal quality, where the signal quality may be, for example, a channel state indication reference signal ( Channel State Indication RS (CSI-RS) quality, cell reference signal (CRS) quality, or Discovery Signal (DS) quality.

Optionally, the determining the second cell includes: the UE listening to the system message of the candidate cell, and determining that the candidate cell is a second cell, where the system message of the candidate cell includes not sending a search Call sign.

The second system message of the second cell includes an identifier that does not send a page, the identifier of the non-sending page is used to indicate that the second node does not send the paging message, or is used to indicate that the second node is only in the The second cell sends a paging message of at least one of: a paging message for notifying the second system message update of the second cell; for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification Paging message; paging for informing the commercial mobile alert service CMAS notification Message.

Similarly, the content of the foregoing identifier for not transmitting a paging is also applicable to other cells (for example, other cells other than the second cell, for example, a third cell, a fourth cell), where the system message of the other cell includes not sending a search. Call sign. It is only necessary to change the second cell in the above content to the name of another cell.

Similarly, in the embodiment, the identifier of the candidate cell is also included in the configuration information of the candidate cell, and the identifier related content that does not send the paging is also applicable to the candidate cell, for example, indicating that the UE in the candidate cell is receiving. Two possibilities for paging messages or two possibilities for the candidate cell to send paging messages. The description will not be repeated here.

The identifier of "no paging to be sent" in all the embodiments of the present invention may also be other names, such as the second identifier, which is not limited by the present invention.

Optionally, the UE camps on the first cell, and receives the first system message of the first cell, where the first system message of the first cell may further include: sending a paging identifier. The sending paging identifier may also be another name, such as the first identifier, which is not limited by the present invention. The sending of the paging identifier can indicate four possibilities:

A) for transmitting paging information to the UE (to transmit paging information to a UE).

B) The first system message used to notify the UE that the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS Notification (Commercial Mobile Alert Service, CMAS).

Further, the UE receives a paging message only from the first cell; or the UE receives a paging message in the first cell, and the UE receives a paging message in the second cell, The UE receives, in the second cell, a paging message of at least one of the following: the UE receiving the paging message in the second cell includes at least one of the following: a second for notifying the second cell A paging message updated by the system message; a paging message for notifying the first notification of the earthquake tsunami system ETWS and/or the second notification of the ETWS; a paging message for informing the commercial mobile alert service CMAS to notify.

First, "the UE, receiving a paging message only from the first cell" can be understood as: Reselecting when the first cell (or the UE reselects the determined new first cell when the first cell performs the first cell reselection) and the second cell (or the UE performs the second cell reselection in the second cell) After determining the new second cell, the UE only receives the paging message from the first cell (or the new first cell after the first cell reselection is performed by the UE in the first cell), and does not receive the paging message. The second cell (or the UE reselects the determined new second cell when the second cell performs the second cell reselection) receives any paging message. The UE receives the paging message (the UE selects and monitors the indicated paging channels of the cell), and the paging message is used for at least one of the following:

A) used to transmit paging information to the UE (to transmit paging information to a UE).

B) used to notify the UE that the first system message of the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS Notification (Commercial Mobile Alert Service, CMAS).

Specifically, the present invention recommends that the paging message is used to transmit paging information to a UE. Alternatively, the paging message may be used for other three types (B). One or more of /C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation.

Second, regarding "the UE receives a paging message in the first cell, and the UE receives a paging message in the second cell, the UE receiving the paging message in the second cell includes At least one of: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for notifying a paging message notified by the CMAS of the commercial mobile alert service. "may be: "the UE receives the paging message in the first cell" (may be UE selects and monitors the indicated paging channels of the cell), in the first cell The paging message is for at least one of the following:

A) for transmitting paging information to the UE (to transmit paging information to a UE).

B) The first system message used to notify the UE that the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS Notification (Commercial Mobile Alert Service, CMAS).

Specifically, the present invention recommends that the paging message is used to transmit paging information to the UE (to transmit paging information to a UE). Optionally, the paging message may also be used in other three types (B/ One or more of C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation.

In addition, on the basis of the foregoing, in the second cell, the UE may receive a paging message in the second cell, and the UE receiving the paging message in the second cell includes at least one of the following: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial mobile alarm service CMAS notification Paging message.

The above four types (one or more of the ABCDs) may be implemented in the same paging message, or may be implemented in multiple paging messages, and the present invention does not limit the specific content included in the specific paging message, but only Describe the paging message received by the UE in the second cell, and the paging message may be used for which purpose or for which purpose. This paragraph can also be applied to other embodiments, not repeated.

Regarding how to determine the second cell, the cell reselection method of the prior art may also be used. In the second cell determined in the present invention, the UE does not receive the paging message of the first case in the second cell. For example, the behavior performed by the UE in the second cell after determining the second cell is different from the behavior of the UE camping on the first cell in that the UE does not receive the first paging message in the second cell, or the second cell does not. The first type of paging message will be sent to the UE. Of course, there are other behaviors that are different from staying in a cell, and the present invention is not limited.

Regarding how to determine the second cell, the UE may obtain one or more cells that satisfy the selection condition by selecting and comparing a cell that satisfies the condition as the second cell, for example, in the candidate cell by measurement and comparison. (For example, cell A), first listen to the system message of the cell A. If the cell A system message includes an indication that the paging message is not sent (the identity of the paging is not sent), the UE confirms that the cell is a The cell that does not send the paging message is therefore selected as the second cell. The system message of the cell A, which is what we later said The second system message of the two cells.

The UE does not receive the paging message in the second cell, or the second cell does not send the paging message to the UE. There are two meanings from the perspective of the second cell. Regarding the second cell not transmitting the paging message, there are two possibilities:

1) The second cell does not send any paging message to the UE.

2) The receiving, by the UE, the paging message in the second cell includes at least one of: a paging message for notifying the second system message update of the second cell; and notifying the earthquake tsunami system ETWS a first notification and/or a paging message of the ETWS second notification; a paging message for informing the commercial mobile alert service CMAS to notify.

Correspondingly, from the perspective of the UE, the UE does not receive the paging message in the second cell, and there are two possibilities:

1) The UE does not receive any paging message in the second cell.

2) The UE receives at least one of the following in the second cell: a paging message for notifying the second system message update of the second cell; for notifying the earthquake tsunami system ETWS first notification and/or ETWS second A paging message for notification; a paging message for informing the commercial mobile alert service CMAS to notify.

Optionally, before determining that a cell is used as the second cell, the UE may listen to the system message of the cell, for example, may obtain an identifier that does not send a paging from a system message of the cell, where the identifier of not sending the paging For indicating that the cell is a cell that does not send a paging message, the UE may determine that the cell may be selected as the second cell of the UE. Specifically, after the UE selects and compares the multiple candidate cells, after selecting the high-quality cell, the UE may listen to the system message of the high-quality cell and determine that the high-quality cell is the second cell. Of course, the UE may also obtain a cell or a set of cells that do not send a paging message from the indication message sent by the first cell (for example, by using such cell information that does not send a paging message provided in the indication message), thereby measuring These cells determine that one cell (e.g., a high quality cell) is the second cell. Here, how to determine that a cell is a second cell is not limited in the present invention. Such a cell that does not send a paging message does not send a paging message as if the second cell does not send a paging message, and there are two possibilities:

1) The cell does not send any paging message to the UE.

2) The UE receives at least one paging message of the following at the cell: a paging message for notifying the system message update of the cell; for notifying the first notification about the earthquake tsunami system ETWS and/ Or a paging message of the second notification of the ETWS; a paging message for informing the commercial mobile alarm service CMAS to notify.

Optionally, the UE may, after determining that the cell is the second cell, may listen to the system message of the cell, and the UE may further obtain, from the system message, the TA identifier that the cell belongs to, where the TA identifier is used to indicate that the cell belongs to TA area. If the TA identity of the cell is the same as the TA identity of the first cell, it means that the cell is in the same TA zone as the first cell. If the TA identity of the cell is different from the TA identity of the first cell, it means that the cell is not in the same TA zone as the first cell. Of course, how to distinguish whether the first cell and the second cell are in the same TA may use different methods, and the invention is not limited. Whether the TA of the first cell and the TA of the second cell are consistent, and the present invention is not limited.

S104: The UE receives the second system message of the second cell, and performs measurement on the second cell.

Note that: in all embodiments of the present invention, the UE receives the second system message of the second cell, and may also be the second system message that the UE listens to the second cell. That is to say, the "receive" system message may also be a "listening" system message, and the present invention does not impose any specific limitation.

Optionally, the UE performs the measurement on the second cell, and the method includes: the UE performs measurement on the second cell according to the first system message or the second system message, and performs the second cell according to the measurement result. Cell reselection. The first system message or the second system message may include configuration information of the second cell, and the UE performs cell reselection evaluation according to the configuration information of the second cell, thereby determining whether to perform cell reselection.

Further, the UE performs measurement on the second cell according to the first system message or the second system message, and performs cell reselection of the second cell according to the measurement result: specifically: if the UE measurement center If the signal quality of the second cell is less than or equal to the first threshold, the UE further includes: performing the same-frequency cell of the second cell and/or performing an inter-frequency cell with a lower priority than the second cell. Measured to enable the UE to perform cell reselection of the second cell; or, the UE performs measurement on the inter-frequency cell with a higher priority than the second cell, if the priority is higher than the second cell If the signal quality of the inter-frequency cell is greater than or equal to the second threshold, the UE performs cell reselection of the second cell.

After determining the second cell: the UE may receive the second system message of the second cell in the second cell (eg, cell X), and perform measurement on the second cell. In the second cell, when the signal quality of the second cell is degraded, the cell may also perform cell reselection, so that the UE finds a better signal in a signal. The appropriate second cell (for example, cell Y), the cell Y is similar to the cell X, that is, after the UE reselects to the cell Y, the UE does not receive the paging message in the cell Y, or the cell Y does not send the paging message for the UE. For example, the cell Y is similar to the cell X. The behavior of the UE in the cell Y after determining the cell Y is different from the behavior of the UE camping in a first cell. The UE does not receive the paging message in the cell Y, or is the cell Y. No paging message will be sent for the UE.

Optionally, the first cell and the second cell in the foregoing S101-S104 may be cells in the same tracking area. Of course, it may be different, and the invention is not limited.

Optionally, the UE is still camped on the first cell in the process of determining the second cell or after determining the second cell according to the indication message; or the UE is determining the second cell. During or after the process, the UE performs cell reselection of the first cell. That is to say, the UE can do two things in parallel. The first thing is that the UE camps on the first cell. In the prior art, the UE only resides in one cell, and the present invention can continue to be used. For example, the UE selects a suitable cell camping in which the UE obtains various configuration information, such as paging message configuration, according to system messages sent by the cell, so as to be able to listen and receive networks in the paging channel (eg, a paging message sent by a Public Land Mobile Network (PLMN); and a system message listening to the cell, for example, access configuration, paging configuration, cell selection/reselection configuration, TA Information, etc. It is also possible to obtain, for example, receiving access layer and non-access stratum information and the like. For example, the system message may specifically include the following configurations but is not limited to the following configurations:

MIB: DL BW, PHICH configuration, SFN;

SIB1: PLMN ID, Cell Global ID, Cell barred status, cell selection information, CSG indication, scheduling information, valuetag;

SIB2: ACB information,radioresourceconfigurationcomm, UL BW;

SIB3: cell reselection information (serving cell information, speed scale information).

Measurements are performed to facilitate the cell reselection evaluation process. (Note: If the signal quality of the cell is not good, it is possible to reselect to other cells. In addition, if other cells and the cell are not the same TA, the UE will start the TA update process, so that the MME knows that the UE is up. In other TA areas.) When receiving a message for paging the UE in the cell, the UE initiates random access in the cell to establish a radio resource control RRC connection.

The second thing is that the UE determines a second cell and receives the second cell in the second cell. The second system message measures the second cell. After the UE determines a second cell, cell reselection can be performed. In addition, specifically, for example, the behavior performed by the UE in the second cell after determining the second cell is different from the behavior of the UE camping on one cell, for example, the UE does not receive the paging message in the second cell, or is the second The cell does not send a paging message to the UE. The UE may not perform TA update in the second cell, and the TA update is only performed in the first cell. The UE may not establish an RRC connection in the cell or may establish an RRC connection in the cell. The UE may receive the ETWS notification (the first ETWS notification and/or the second ETWS notification) and the CMAS notification in the second cell, of course, the UE may not receive the ETWS notification and the CMAS notification in the second cell but receive in the first cell, The invention is not limited.

In short, the UE ensuring the idle state can always camp on one cell (for example, the first cell, or the new first cell determined after the cell reselection in the first cell), and in another cell (for example, the second cell, Or receiving a system message of the cell in a new second cell determined after performing cell reselection in the second cell, performing measurement, performing cell reselection, and the like. It should be emphasized that, for receiving the paging message, for the first cell (or the UE reselects the determined new first cell when the first cell performs the first cell reselection) and the second cell (or the UE is When the second cell performs the second cell reselection, reselecting the determined new second cell), the first possibility, "the UE, only receiving the paging message from the first cell", or the second type The UE may receive a paging message in the first cell, and the UE receives a paging message in the second cell, and the UE receiving the paging message in the second cell includes the following at least a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial mobile The paging message notified by the alert service CMAS.

The first possibility is that the “the UE only receives the paging message from the first cell” may be understood as: for the first cell (or the UE reselects when performing the first cell reselection in the first cell) Determining the new first cell) and the second cell (or the UE reselecting the determined new second cell when the second cell performs the second cell reselection), the UE only from the first cell (or the UE When the first cell performs the first cell reselection, the reselected new first cell receives the paging message, and does not reselect from the second cell (or the UE performs the second cell reselection in the second cell). The determined new second cell receives any paging message. The UE receives the paging message (the UE selects and monitors the indicated paging channels of the cell), and the paging message is used for at least one of the following:

A) used to transmit paging information to the UE (to transmit paging information to a UE).

B) used to notify the UE that the first system message of the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS Notification (Commercial Mobile Alert Service, CMAS).

Specifically, the present invention recommends that the paging message is used to transmit paging information to a UE. Alternatively, the paging message may be used for other three types (B). One or more of /C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation.

Second, regarding "the UE receives a paging message in the first cell, and the UE receives a paging message in the second cell, the UE receiving the paging message in the second cell includes At least one of: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for notifying a paging message notified by the CMAS of the commercial mobile alert service. "may be: "the UE receives the paging message in the first cell" (may be UE selects and monitors the indicated paging channels of the cell), in the first cell The paging message is for at least one of the following:

A) for transmitting paging information to the UE (to transmit paging information to a UE).

B) The first system message used to notify the UE that the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS Notification (Commercial Mobile Alert Service, CMAS).

Specifically, the present invention recommends that the paging message is used to transmit paging information to the UE (to transmit paging information to a UE). Optionally, the paging message may also be used in other three types (B/ One or more of C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation. Above 4 (One or more of the ABCDs) may be implemented in the same paging message, or may be implemented in multiple paging messages. The present invention does not limit the specific content included in the specific paging message, but only describes the UE. A paging message received at the second cell, which purpose the paging message may be or a paging message for which purpose. This paragraph can also be applied to other embodiments, not repeated.

In addition, on the basis of the foregoing, in the second cell, the UE may receive a paging message in the second cell, and the UE receiving the paging message in the second cell includes at least one of the following: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial mobile alarm service CMAS notification Paging message. One or more of the above three types may be implemented in the same paging message, or may be implemented in multiple paging messages. The present invention does not limit the specific content included in the specific paging message, but only indicates that the UE is in the A paging message received by the second cell, which may be a purpose or a paging message for which purpose. This paragraph can also be applied to other embodiments, not repeated.

That is to say, the UE may not receive any paging message in the second cell, and may also receive a limited paging message of the one or more uses in the second cell. For example, the UE only receives a paging message for notifying the second system message update of the second cell in the second cell, and receives a paging message for transmitting paging information in the first cell UE and is used to notify the first The paging message of the cell first system message update; optionally, the UE may also receive the paging message for other purposes in the first cell.

In summary, that is, the UE may not receive any paging message in the second cell, and may also receive a limited paging message of the one or more uses in the second cell. For example, the UE only receives a paging message for notifying the second system message update of the second cell in the second cell, and other paging messages may be received in the first cell, for example, receiving a paging message in the first cell. One or more of the above ABCD items.

Therefore, for the behavior of the UE in the second cell, specifically, for example, the behavior performed by the UE in the second cell after determining the second cell is different from the behavior of the UE camping on one cell, that is, the UE is in the second cell. Do not receive paging messages or only receive paging messages for one/several types of purposes (as described above). Of course, the behavior of the UE in the second cell may also be different from the behavior of camping in the first cell, and the present invention does not impose too many restrictions. The UE may perform cell reselection in the first cell to determine that a new first cell camps, and the UE may also perform cell reselection in the second cell. Set a new second cell. Thus, the UE can always stay in one cell while receiving the system message, measurement, etc. of the cell in another cell, but the UE behavior is different in the two cells for receiving the paging message. .

Further, if the UE receives the paging message in the first cell, the UE initiates random access in the second cell and/or establishes an RRC connection in the second cell; and/or if the UE receives the paging in the first cell The message, the UE initiates random access in the first cell and/or establishes a radio resource control RRC connection in the first cell. If the UE receives the paging message in the first cell, the UE sends the information of the second cell to the first node, so that the first node determines, according to the information of the second cell, the dual connectivity service for the UE. The node sends a request message to the second node according to the information of the second cell, and the request message is used to request the second node to be the dual-connected secondary node of the UE. Therefore, the two corresponding nodes of the cell can simultaneously serve the UE. In this case, the UE may perform random access or establish an RRC connection with the first cell, and the UE provides information of the second cell to the first node. The information of the second cell includes at least one of the following: an E-UTRAN Cell Global Identifier (ECGI) of the second cell, a physical cell identifier PCI of the second cell, and a second node identifier ENB corresponding to the second cell. ID.

Optionally, the UE receives the second system message of the second cell, and after performing measurement on the second cell, the UE records information of the second cell, and still resides in the first Community.

The embodiment provides a method for determining a cell, including: the UE camps on the first cell, the UE receives the paging message sent by the first node, and determines the second cell according to the paging message, and then the UE receives the second cell. The second system message, and the measurement is performed on the second cell, where the UE only receives the paging message from the first cell, but generally the signal quality of the second cell is relatively good. Therefore, the embodiment provides determining the second cell. The method is such that the UE receives the paging message only in the first cell, thereby reducing resource consumption and network load, and the first cell and/or the second cell corresponding node can implement data service transmission for the UE, thereby improving the efficiency of transmitting the data service. .

Specifically, for example, by using the foregoing implementation, it can be ensured that the UE can always camp on one cell (for example, the first cell, or the new first cell determined after the cell reselection in the first cell), and at the same time, in another cell. The system message of the cell is received (for example, the second cell or the new second cell determined after the second cell performs cell reselection), and measurement is performed to perform cell reselection and the like. It should be emphasized that, for receiving the paging message, for the first cell (or the UE reselects the determined new first cell when the first cell performs the first cell reselection) and the second cell (or the UE is When the second cell performs the second cell reselection, reselecting the determined new second cell), the first possibility, "the UE, only receiving the paging message from the first cell", or the second type The UE may receive a paging message in the first cell, and the UE receives a paging message in the second cell, and the UE receiving the paging message in the second cell includes the following at least a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial mobile The paging message notified by the alert service CMAS".

S803: The UE camps on the first cell.

S804: The UE receives the second system message of the second cell, and performs measurement on the second cell.

Specifically, the performing, by the UE, the second cell: the UE, according to the first system message of the first cell or the second system message of the second cell, to the second cell The measurement is performed, and cell reselection of the second cell is performed according to the measurement result. The UE performs measurement on the second cell according to the first system message of the first cell or the second system message of the second cell, and performs cell reselection of the second cell according to the measurement result: specifically including If the UE measures that the signal quality of the second cell is less than or equal to the first threshold, the UE further includes a co-frequency cell to the second cell and/or a priority lower than the first The inter-frequency cell of the second cell performs measurement to enable the UE to perform cell reselection of the second cell; or the UE performs measurement on the inter-frequency cell with a higher priority than the second cell, if the priority If the inter-frequency cell signal quality of the second cell is greater than or equal to the second threshold, the UE performs cell reselection of the second cell.

Further, if the UE receives a paging message in the first cell, the UE initiates random access in the second cell and/or establishes a radio resource control RRC connection in the second cell; and Or, if the UE receives a paging message in the first cell, the UE initiates a random access in the first cell and/or establishes a radio resource control RRC connection in the first cell.

The information of the second cell includes at least one of the following: a cell global identifier ECGI of the second cell, a physical cell identifier PCI of the second cell, and a second node identifier ENB ID corresponding to the second cell. . In the above steps, the first cell and the second cell are cells in the same tracking area.

Optionally, the UE receives the second system message of the second cell, and after performing measurement on the second cell, the UE records information of the second cell, and still resides in the first Community.

Specifically, for example, by using the foregoing implementation, it can be ensured that the UE can always camp on one cell (for example, the first cell, or the new first cell determined after the cell reselection in the first cell), and at the same time, in another cell. The system message of the cell is received (for example, the second cell or the new second cell determined after the second cell performs cell reselection), and measurement is performed to perform cell reselection and the like. It should be emphasized that, at the same time, the system message of the cell is received in another cell (for example, the second cell or the new second cell determined after the cell reselection in the second cell), and measurement is performed to perform cell reselection. Wait. It should be emphasized that, for receiving the paging message, for the first cell (or the UE reselects the determined new first cell when the first cell performs the first cell reselection) and the second cell (or the UE is When the second cell performs the second cell reselection, reselecting the determined new second cell), the first possibility, "the UE, only receiving the paging message from the first cell", or the second type The UE may receive a paging message in the first cell, and the UE receives a paging message in the second cell, and the UE receiving the paging message in the second cell includes the following at least a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial mobile The paging message notified by the alert service CMAS.

The first possibility is that the “the UE only receives the paging message from the first cell” may be understood as: for the first cell (or the UE reselects when performing the first cell reselection in the first cell) Determining the new first cell) and the second cell (or the UE reselecting the determined new second cell when the second cell performs the second cell reselection), the UE only from the first cell (or the UE When the first cell performs the first cell reselection, the reselected new first cell receives the paging message, and does not reselect from the second cell (or the UE performs the second cell reselection in the second cell). The determined new second cell receives any paging message. The UE receives a paging message in the first cell (may The UE selects and monitors the indicated paging channels of the cell, and the paging message is used for at least one of the following:

A) used to transmit paging information to the UE (to transmit paging information to a UE).

B) used to notify the UE that the first system message of the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS notification.

Specifically, the present invention recommends that the paging message is used to transmit paging information to a UE. Alternatively, the paging message may be used for other three types (B). One or more of /C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation.

Second, regarding "the UE receives a paging message in the first cell, and the UE receives a paging message in the second cell, the UE receiving the paging message in the second cell includes At least one of: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for notifying a paging message notified by the CMAS of the commercial mobile alert service. "may be: "the UE receives the paging message in the first cell" (may be UE selects and monitors the indicated paging channels of the cell), in the first cell The paging message is for at least one of the following:

A) for transmitting paging information to the UE (to transmit paging information to a UE).

B) The first system message used to notify the UE that the first cell is updated (to inform UEs about a system information change).

C) for notifying the UE about the earthquake tsunami system ETWS first notification and/or ETWS secondary notification (to inform about an ETWS primary notification and/or ETWS secondary notification).

D) Used to inform the UE of the CMAS notification.

Specifically, the present invention recommends that the paging message is used to transmit paging information to the UE (to transmit paging information to a UE). Optionally, the paging message may also be used for other paging messages. One or more of three types (B/C/D items). Of course, in addition to the above four types, the paging message received by the UE in the first cell can also be used for other purposes, and the present invention does not impose any limitation. The above four types (one or more of the ABCDs) may be implemented in the same paging message, or may be implemented in multiple paging messages, and the present invention does not limit the specific content included in the specific paging message, but only Describe the paging message received by the UE in the second cell, and the paging message may be used for which purpose or for which purpose. This paragraph can also be applied to other embodiments, not repeated.

In addition, on the basis of the foregoing, in the second cell, the UE may receive a paging message in the second cell, and the UE receiving the paging message in the second cell includes at least one of the following: a paging message for notifying the second system message update of the second cell; a paging message for notifying the earthquake tsunami system ETWS first notification and/or the ETWS second notification; for informing the commercial mobile alarm service CMAS notification Paging message. One or more of the foregoing three types may be implemented in the same paging message, or may be implemented in multiple paging messages. The present invention does not limit the specific content included in the specific paging message, but only indicates that the UE is in the first A paging message received by the second cell, which purpose the paging message may be or a paging message for which purpose. This paragraph can also be applied to other embodiments, not repeated.

That is to say, the UE may not receive any paging message in the second cell, and may also receive a limited paging message of the one or more uses in the second cell. For example, the UE only receives a paging message for notifying the second system message update of the second cell in the second cell, and receives a paging message for transmitting paging information in the first cell UE and is used to notify the first The paging message of the cell first system message update; optionally, the UE may also receive the paging message for other purposes in the first cell.

In summary, that is, the UE may not receive any paging message in the second cell, and may also receive a limited paging message of the one or more uses in the second cell. For example, the UE only receives a paging message for notifying the second system message update of the second cell in the second cell, and other paging messages may be received in the first cell, for example, receiving a paging message in the first cell. One or more of the above ABCD items.

Therefore, for the behavior of the UE in the second cell, specifically, for example, the behavior performed by the UE in the second cell after determining the second cell is different from the behavior of the UE camping on one cell, that is, the UE is in the second cell. Do not receive paging messages or only receive paging messages for one/several types of purposes (as described above). Of course, the behavior of the UE in the second cell may also be different from the behavior of camping in the first cell, and the present invention does not impose too many restrictions. The UE may perform cell reselection in the first cell. A new first cell camp is determined, and the UE may also perform cell reselection in the second cell to determine a new second cell. Thus, the UE can always stay in one cell while receiving the system message, measurement, etc. of the cell in another cell, but the UE behavior is different in the two cells for receiving the paging message. .

The embodiment provides a method for determining a cell, including: first, a UE receives a second system message sent by a second node corresponding to a second cell; then, the UE determines a first cell according to the second system message; and the UE receives the second a second system message of the cell, and performing measurement on the second cell; thereby reducing resource consumption and network load, and the UE may perform data service transmission for the first cell and/or the second cell corresponding node, thereby improving transmission data. Business efficiency.
