DETAILED DESCRIPTION

Moreover, while the flow charts illustrate logical sequences, in some cases, the illustrated or described methods may be performed in sequences other than the sequences described herein.

Embodiments of the present application can be applied to wireless networks of different formats. A wireless access network can include different communication nodes in different systems. Fig. 1 is a block diagram of a wireless network system provided by the present application. As shown in Fig. 1, a wireless network system 100 includes a base station 101, UE 110, UE 120 and UE 130. The base station 101 performs wireless communication with UE 110, UE 120 and UE 130, respectively.

In an embodiment of the present application, the base station may be a device capable of communicating with the UE. The base station may be any device with a wireless transceiver function, including, but not limited to, a base station (Node-B, NB) evolved Node-B (eNB), a base station in a 5G communication system, a base station in a future communication system, an access node in a WiFi system, a wireless repeater node, a wireless backhaul node, and the like. The base station may also be a small station, a transmit/receive point (TRP), and the like, which is not limited to the embodiments of the present application.

Alternatively, the UE can also be deployed above water (for example, on a ship and the like), and can also be deployed in the air (for example, on an airplane, a balloon, a satellite and the like). The UE can be a mobile phone, a tablet, a computer with a wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal for controlling an industrial process, a wireless terminal for providing unmanned control, a wireless terminal for remote medical examination, a wireless terminal for an intelligent power grid, a wireless terminal for providing transportation service security, a wireless terminal for an intelligent city system, a wireless terminal for an intelligent home system, and the like.

In an exemplary embodiment, Fig. 2 is a flow chart of a method for determining a measurement time provided by the present application. The method can be applied to the case of performing an ANR measurement. The method can be performed by an apparatus for determining a measurement time provided by the present application, and the apparatus for determining a measurement time can be implemented by software and/or hardware, and integrated into a UE.

As shown in Fig. 2, the method for determining the measurement time provided by the present application includes steps S210, S220 and S230.

Automatic Neighbor Relationship (ANR) is an important function of the self-organizing network (SON). ANR ensures the integrity and validity of neighbor relationships through automatic maintenance so as to reduce abnormal handover between neighbors. The purpose of ANR is to reduce the complexity of the communication network, save network maintenance costs, reflect the network neighbor relationships in a timely and accurate manner, and improve the network efficiency. ANR is established based on the base station interacting with the Operations and Management (O&M) device through the UE so as to automatically identify and create neighbor relationships and provide continuous optimization services such as neighbor cell detection, neighbor relationship addition and deletion, neighbor relationship attribute modification, and the like.

In NB-IoT, only the UE in the idle state can perform ANR measurement. However, due to the different measurement capabilities of the UE, the time required to obtain measurement results under the same conditions is different; and when the UE performs ANR measurement, not all carriers can meet the ANR reporting requirements. For example, if there is no cell that meets the ANR reporting requirements among all the measurements, the corresponding measurements fail to be obtained. Moreover, when the ANR measurement is performed in the NB-IoT standard, the measurement relaxation, SIntraSearchP/SIntraSearchQ, and the decision SnonIntraSearchP/SnonIntraSearchQ cannot be performed. When the reference received signal power (RSRP) of the serving cell is less than SSearchDeltaP, the neighbor measurement cannot be performed. When the wireless communication quality of the serving cell is higher than a certain threshold (SIntraSearchP/SIntraSearchQ), the intra-frequency neighbor measurement cannot be performed; When the wireless communication quality of the serving cell is higher than a certain threshold (SnonIntraSearchP/SnonIntraSearchQ), it is impossible to perform inter-frequency neighbor measurement and inter-system neighbor measurement. This means that the UE consumes more electric power when the UE performs ANR measurement than when the UE is in normal idle mode. When the UE performs the measurement but fails to obtain the ANR measurement results, i.e., when the UE camps on an isolated cell or the RSRP of the neighboring cell relative to the cell in which the UE camps is very low, the UE will perform the ANR measurement for a long time and consume a large amount of electric power.

In step S210, ANR configuration information is received, wherein the configuration information includes an ANR measurement duration or an ANR measurement timer.

When the UE enters the idle mode, the UE immediately performs the ANR measurement once requested by the base station and performs the measurement on the frequency list and cell list that are included in the ANR measurement configuration information.

In specific applications, UEs with different measurement capabilities may require different times to obtain serving cells that meet the conditions. In another example, when a UE performs ANR measurement and fails to obtain a set of ANR measurement results, the UE will repeatedly perform ANR measurement for a long time, which is contrary to the energy saving goal of the NB-IoT standard.

As a result, in addition to the original measurement configuration parameter, the eNB further includes an ANR measurement time parameter in the ANR configuration information, and the ANR measurement time parameter may be an ANR measurement duration or an ANR measurement timer.

The ANR measurement duration or ANR measurement timer includes at least one of the following: a duration in seconds and/or milliseconds, a duration in units of discontinuous reception (DRX) periods, or a duration in units of the product of the DRX period and the number of measured carriers.

The ANR measurement time parameter values configured for UEs with different measurement capabilities may be different to achieve the energy saving goal of the NB-IoT standard.

The ANR configuration information is configured by the eNB base station and sent to the UE. The UE receives the ANR configuration information sent by the base station.

In step S220, the ANR measurement is performed based on the configuration information.

In the NB-IoT standard, when the UE enters the idle mode, the UE immediately performs a one-time requested ANR measurement and performs the measurement on the frequency list and cell list that are included in the ANR configuration information.

In step S230, in the case where the first condition is satisfied, the ANR measurement is completed, where the first condition includes at least one of the following: the ANR measurement duration is reached, the ANR measurement timer expires, or the ANR measurement result is obtained.

After all the measurements on the frequency list and cell list are completed, there may be no serving cell that satisfies the condition. For example, when the UE camps on an isolated cell or the RSRP of the neighboring cell is very low, the UE will repeatedly perform ANR measurement for a long time, which is contrary to the purpose of saving energy in the NB-IoT standard.

The problem that the ANR measurement is performed for too long a time in the above case is limited by the ANR measurement duration or the ANR measurement timer in the ANR measurement configuration information.

The ANR measurement duration or the ANR measurement timer is set according to the difference in the measurement capabilities of the UE and the difference in the frequency lists and cell lists in the ANR measurement configuration, and may be a time parameter of one second and/or one millisecond or a time parameter in units of DRX periods or in units of the product of the DRX period and the number of measured carriers so as to effectively avoid unnecessary losses in the measurement process.

In the technical solution provided in this embodiment of the present application, a situation is avoided in which a UE performs an ANR measurement for a long time and consumes a large amount of electric power when a failure occurs in obtaining an ANR measurement in some cases, and by implementing the concept of a time parameter for performing an ANR measurement, the longest ANR measurement time that the UE can support is specified, thereby reducing the power consumption of the UE in the NB-IoT standard.

In an exemplary embodiment, in the NB-IoT standard, when a UE enters the idle mode, the UE performs a measurement on a frequency list and a cell list included in the ANR configuration information. After all the measurements on the frequency list and the cell list are completed, a set of ANR measurement results is obtained, then the ANR measurement is completed to obtain the measurement result, and the measurement result is sent to the base station in the next RRC process. A situation in which the ANR measurement is repeated after a set of ANR measurement results is obtained is prevented, thereby achieving the purpose of energy saving in the NB-IoT standard.

In an exemplary embodiment, Fig. 3 is a flow chart of another method for determining the measurement time provided by the present application. The method can be applied to the case of performing an ANR measurement. The method can be performed by the apparatus for determining the measurement time provided by the present application, and the apparatus for determining the measurement time can be implemented by software and/or hardware, and integrated into a base station.

As shown in Fig. 3, the method for determining the measurement time provided by the present application includes steps S310 and S320.

In step S310, the ANR measurement duration or the ANR measurement timer is configured in the ANR configuration information.

In specific applications, UEs with different measurement capabilities may require different times to obtain serving cells that satisfy the conditions.

In addition to the original measurement configuration parameter, the eNB further includes one ANR measurement time parameter in the ANR configuration information, and the ANR measurement time parameter may be an ANR measurement duration or an ANR measurement timer.

The measurement duration or ANR measurement timer includes at least one of the following: a duration in seconds and/or milliseconds, a duration in units of DRX periods, or a duration in units of the product of the DRX period and the number of measured carriers.

The ANR measurement time parameter values configured for UEs with different measurement capabilities may be different to achieve the energy saving goal of the NB-IoT standard.

In step S320, the configuration information is sent to the UE.

In an exemplary embodiment, the configuration information is configured via a SIB and/or a radio resource control (RRC) connection release message.

In the technical solution provided in this embodiment of the present application, a situation is avoided in which a UE performs an ANR measurement for a long time and consumes a large amount of electric power when a failure occurs in obtaining an ANR measurement in some cases, and by implementing the concept of a time parameter for performing an ANR measurement, the longest ANR measurement time that the UE can support is specified, thereby reducing the power consumption of the UE in the NB-IoT standard.

In an exemplary embodiment, Fig. 4 is a flow chart of a method for determining a camping cell provided by the present application. The method can be applied to the case of determining camping of a TSC of a UE. The method can be performed by an apparatus for determining a camping cell provided by the present application, and the apparatus for determining a camping cell can be implemented by software and/or hardware and integrated into the UE.

In order to support TSC traffic, the gNB must send precise timing reference to the UE, and the time granularity must satisfy the TSC delay accuracy requirements. However, since additional radio resources are required to provide precise timing reference, not all cells support the transfer of such precise timing reference. In addition, some gNBs that do not support the transfer of precise timing reference information cannot support the transfer of precise timing reference. As a result, only some gNBs/cells support TSC traffic. If a UE carrying TSC traffic camps on a cell without transferring precise timing reference, the TSC traffic cannot be performed normally, which affects the availability of TSC traffic.

As shown in Fig. 4, the method for determining a fixation cell provided by the present application includes steps S410 and S420.

In step S420, at least one neighbor cell list sent by the base station is received.

In step S420, a target list of neighboring cells is determined from at least one list of neighboring cells based on the capability information of the terminal, wherein the capability information of the terminal includes at least one of the following: whether the terminal supports TSC traffic, or synchronization information that is required by the terminal to carry TSC traffic.

The TSC service of a terminal includes the fact that the terminal is a TSC terminal and that the traffic carried by the terminal is TSC traffic.

The UE selects an appropriate list of neighbor cells based on the terminal capability information in the cell selection and reselection process in such a way as to determine a range of potential target cells. The terminal capability information includes at least one of the following: whether the terminal supports TSC traffic, or synchronization information that the terminal requires to carry TSC traffic. The UE requires accurate synchronization information to operate.

In an exemplary embodiment, the corresponding target list of neighbor cells is determined based on the terminal capability information in one of the following ways.

In the case where the terminal supports TSC traffic, a neighbor cell list including a cell supporting TSC traffic is determined as a target neighbor cell list; or a neighbor cell list including a cell providing reference synchronization information is determined as a target neighbor cell list.

The target neighbor cell list includes an intra-frequency cell list and/or an inter-frequency cell list.

In order to support TSC traffic, in case that not all cells can support the transfer of precise timing reference and some legacy gNBs can no longer support the delivery of precise timing reference, the intra-frequency neighbor cell list and the inter-frequency neighbor cell list that provide precise timing reference in SIB9 can be specified through SIB3 and SIB4, respectively.

The intra-frequency neighbor cell list and the inter-frequency neighbor cell list are specified in accordance with SIB3 and SIB4, and the UE performs selection or reselection only on the neighbor cell list that includes the accurate timing reference, instead of on the cells that do not include the accurate timing reference or that are not in the neighbor cell list.

In an exemplary embodiment, Fig. 5 is a flow chart of a method for configuring a neighbor cell list provided by the present application. The method can be applied to the case of determining the camping of a TSC UE. The method can be performed by an apparatus for determining the camping cell provided by the present application, and the apparatus for determining the camping cell can be implemented by software and/or hardware, and integrated into a base station.

As shown in Fig. 5, the method for configuring a neighbor cell list provided by the present application includes steps S510 and S520.

In step S510, neighbor cell lists are configured, wherein the neighbor cell lists are determined by cell capability information, and the cell capability information includes at least one of whether the cell supports TSC traffic or whether the cell provides reference synchronization information.

In step S520, at least one list of neighbor cells is sent to the UE via the SIB.

The neighbor cell lists are configured based on the cell capability information, where the cell capability information includes at least one of the following: whether the cell supports TSC traffic or whether the cell provides reference timing information.

The base station configures neighbor cell lists based on cell capability information, wherein the cell capability information includes at least one of the following: whether the cell supports TSC traffic or whether the cell provides reference timing information, and the neighbor cell lists include a list of intra-frequency/inter-frequency cells.

The neighbor cell lists are configured based on the cell capability information as follows: The neighbor cell lists are configured based on the TSC traffic. All cells included in the neighbor cell lists configured based on the TSC traffic support the TSC traffic. All cells included in the neighbor cell lists configured based on the provision of reference timing information provide reference timing information.

For example, a base station configures a neighbor cell list corresponding to TSC traffic. That is, all neighbor cells in the neighbor cell list corresponding to TSC traffic support TSC traffic.

Configured information can be configured via SIB3 in relation to intra-frequency neighboring cells.

Configured information can be configured via SIB4 in relation to inter-frequency neighboring cells.

In the information configured by the gNB, a list of intra-frequency neighboring cells that provide accurate time reference in SIB9 may be indicated by SIB3, and a list of inter-frequency reference cells that provide accurate time reference in SIB9 may be indicated by SIB4. In the technical solution of this embodiment, a problem is solved that TSC traffic cannot be performed normally because a UE carrying TSC traffic camps on a cell without transferring accurate time reference.

In an exemplary embodiment, Fig. 6 is a flow chart of a method for determining a parameter provided by the present application. The method can be applied to the case of determining a short eDRX parameter of the RRC-Inactive state. The method can be performed by an apparatus for determining the parameter provided by the present application, and the apparatus for determining the parameter can be implemented by software and/or hardware, and integrated into a base station.

As shown in Fig. 6, the method for determining the parameter provided by the present application includes steps S610 and S620.

In step S610, a retransmission timer sent by the core network is received, wherein the retransmission timer includes a NAS retransmission timer or an SMS retransmission timer.

In step S620, the short eDRX RRC-Inactive state parameter is determined in accordance with the retransmission timer.

The short eDRX parameter is determined according to the retransmission timer as follows: the length of the period of the short eDRX parameter is determined according to the retransmission timer, and the length of the period of the short eDRX parameter is less than or equal to the length of the retransmission timer.

The NAS retransmission timer information and the SMS retransmission timer information are sent via the core network in at least one of the following ways.

In the case where an initial context setup request is sent, the NAS retransmission timer information or the SMS retransmission timer information is sent through the core network; in the case where a UE context restore response is sent, the NAS retransmission timer information or the SMS retransmission timer information is sent through the core network; in the case where a retransmission request is sent, the NAS retransmission timer information or the SMS retransmission timer information is sent through the core network; or in the case where a handover path request acknowledgement message is sent, the NAS retransmission timer information or the SMS retransmission timer information is sent through the core network.

The next-generation eNB (ng-eNB) needs to configure parameters regarding short eDRX for the UE in the RRC-Idle state, and the sleep period in the short eDRX is determined by the NAS retransmission timer or the SMS retransmission timer. However, the ng-eNB cannot directly obtain the NAS retransmission timer or the SMS retransmission timer, which cannot guarantee that the length of the short eDRX period is less than or equal to the length of the NAS retransmission timer or the length of the SMS retransmission timer. Therefore, the core network needs to provide the ng-eNB with the length of the NAS retransmission timer and the length of the SMS retransmission timer.

As a result, when a UE dedicated link is created on the S1 interface, the core network provides the base station with a NAS retransmission timer and an SMS retransmission timer so that the base station determines the short eDRX parameter of the RRC-Inactive state, and the NAS retransmission timer and the SMS retransmission timer may be provided in the following messages: initial context setup request, UE context restore response, retransmission request, and retransmission path request.

In an exemplary embodiment, Fig. 7 is a block diagram of another method for determining the measurement time provided by the present application. The method can be applied to the case of determining the paging period. The method can be performed by the apparatus for determining the parameter provided by the present application, and the apparatus for determining the parameter can be implemented by software and/or hardware, and integrated into a base station.

As shown in Fig. 7, the method for determining the parameter provided by the present application includes step S710.

In step S710, the target paging period in the RRC-Idle state is determined based on the PTW in the idle state, wherein the window of the PTW in the idle state determines the location of the window by using the eDRX parameter in the idle mode.

In an exemplary embodiment, the target paging period in the RRC-Idle state is determined based on the PTW in the idle state in at least one of the following ways.

Within the PTW in the Idle state, the shortest period of: the paging period of the radio access network (RAN) configured in the RRC-Idle state; the UE-specific paging period; and the default paging period of the cell, is defined as the target paging period.

Outside the PTW in the Idle state, the RAN paging period configured in the RRC-Idle state is defined as the target paging period.

Within the PTW in the Idle state, the shortest period of the RAN paging period configured in the RRC-Idle state and the UE-specific paging period is defined as the target paging period.

The RAN paging period configured in the RRC-Idle state is configured by the base station for the UE through UE-dedicated signaling as a configuration parameter in the RRC-Idle state, the default paging period for the cell is a paging period parameter broadcast by the base station to the UE, and the UE-specific paging period is a UE-specific DRX period in the Idle state that is sent to the UE by the core network after negotiation between the UE and the core network through the NAS.

The UE in the RRC-Idle state shall monitor the paging channel, where the core network initiates the paging and the paging channel on which the RAN initiates the paging. To monitor the paging initiated by the core network, eDRX in the idle mode is required to be taken into account. For example, the UE may monitor the paging event only during a periodic PTW configured for the UE, or the UE may monitor the paging event until the UE receives a paging message including the NAS identifier of the UE during the PTW, and the earlier of the two cases described above is used. Therefore, a certain degree of coordination is required between the short eDRX of the RRC-Idle state and the eDRX in the idle mode in order to simplify the complexity of the UE.

Therefore, within the PTW in the idle state, in order to monitor the paging initiated by the core network, the paging period T is determined by the shortest period of: the RAN paging period configured in the RRC-IDLE state; the UE-specific paging period (optional) and the default paging period of the cell (optional). Outside the PTW in the idle mode, in order to save the electrical energy consumed by the UE, the paging period T is determined by the RAN paging period T. Therefore, in order to support the eDRX of the RRC-IDLE state and the eDRX in the idle state, the ng-eNB needs to obtain the eDRX parameter in the idle mode in order to determine the paging period T in the RRC-IDLE state.
