Description

 Paging method, device and system

 The present invention relates to the field of communications, and in particular, to a paging method, apparatus, and system. Background technique

 With the rapid development of mobile communication technology, multi-user collaborative communication technology has emerged. In the multi-user cooperative communication technology, the communication between the terminal and the terminal can be realized by using the D2D (Device to Device) technology, so that the UEs (User Equipments) can support each other. In this way, the base station may send data of a certain UE to other UEs in the vicinity of the UE (that is, support the UE), and send data to the UE by supporting a short-distance communication link between the UE and the UE (ie, To benefit the UE).

 During the establishment of the communication link, on the network side, the user plane bearer on the core network side is established only in the manner of establishing a UE requesting to send and receive data. On the base station side, it is required to establish an RB (Radio Bearer) or a part of RBs of multiple UEs according to the information of the multi-UE cooperative communication, so that the downlink data can be sent to the beneficiary UE through multiple RBs.

 In the multi-user cooperative communication technology, if the benefit UE needs to establish multi-user cooperative communication, it needs to send a request message of multi-user cooperative communication to the server serving the server, and the server sends the request message of the multi-user cooperative communication to the core network. On the side, the core network side sends a paging message to the supporting UE of the benefit UE, and then establishes an RB bearer between the UE and the base station. In this way, when the multi-user cooperative communication is established by the benefiting UE, the server must communicate with the server, and the server communicates with the core network side, so that the paging message can be sent to the supporting UE, and the unnecessary signaling interaction and the supporting link are added. Establishing delays limits the efficiency of collaborative communications and ultimately leads to a decline in user experience.

detailed description

 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all 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.

 An embodiment of the present invention provides a paging method, as shown in FIG. 1, including:

1 0 1. The first base station acquires a first trigger message.

 The first trigger message carries at least one short-distance identification information that supports the user equipment UE (U s e r E qu i pmen t , user equipment).

 It should be noted that the short-distance identification information of the UE is information used by other UEs in a close range to discover and identify the UE.

 It should be noted that the supporting UE is relatively in the same way as the benefiting UE. When one UE can transmit data through other UEs, the UE is a benefiting UE, and other UEs that perform data transmission on the UE are the support of the UE. UE.

Specifically, according to different base stations serving the benefit UE, the first base station obtains the first trigger message in two cases. In the first case, the first base station receives the first trigger message sent by the benefiting UE. The benefit UE is a UE served by the first base station.

 It should be noted that, in a case that the benefit UE is a UE served by the first base station, the first base station may directly receive the first trigger message sent by the benefit UE.

 Specifically, if the benefiting UE served by the first base station needs to use the UEs in its vicinity to transmit data, the benefiting UE may obtain the short-distance identification information supporting the UE by using the intercepting manner, and then carry the first information supporting the UE short-distance identification information. The trigger message is sent to the first base station to trigger the first base station to send a paging message to the supporting UE.

 In the second case, the first base station receives the first trigger message sent by the second base station. The second base station is a base station that requests the first base station to send a paging message to the supporting UE, except the first base station.

 Specifically, when the benefit UE is the UE served by the second base station, the benefit UE sends the first trigger message to a second base station serving the same, and then the second base station The first trigger message is sent to the first base station, so that the first base station initiates paging for supporting the UE.

 102. If the at least one supporting UE is a UE serving the first base station, the first base station acquires a network identifier of the at least one supporting UE according to the proximity identification information of the at least one supporting UE.

 Specifically, after acquiring the first trigger message, the first base station first determines whether there is a UE served by the first base station in the supporting UE. If the at least one supporting UE is the UE served by the first base station, the network identifier of the at least one supporting UE may be obtained according to the proximity identification information of the at least one supporting UE carried in the first trigger message.

 It should be noted that the network identifier of the at least one supporting UE may be the IMS I of the UE (International Mobile Subscriber I, the International Mobile Subscriber's J code), or the S-TMSI (System Architecture Evolution Temporary Mobile) Subscriber Ident i ty, user temporary identity).

 It should be noted that the network identifier of the UE may be other identifiers that can uniquely identify the UE, and the present invention does not limit this.

Specifically, the first base station acquires the at least one according to whether the first base station stores a mapping relationship between the network identifier of the at least one supporting UE and the proximity identifier information. The network identity supporting the UE is divided into two cases.

 In the first case, in a case where the first base station stores the mapping relationship between the at least one supporting UE's short-distance identification information and the network identifier, the first base station searches for the advance according to the at least one short-distance identification information of the supporting UE. And storing the first mapping information, and acquiring the network identifier of the at least one supporting UE.

 The mapping between the short-distance identifier of the UE and the network identifier of the UE is recorded in the first mapping information.

 It should be noted that, in this case, before acquiring the first trigger message, the first base station has previously acquired and stored the mapping relationship between the proximity identifier of the serving UE and the network identifier, that is, the first mapping has been stored. information.

 In the second case, in a case where the first base station does not store the mapping relationship between the at least one supporting UE and the network identifier, the first base station passes the proximity identification information of the at least one supporting UE. The proximity server acquires the network identifier of the at least one supporting UE.

 The short-range server refers to a server that stores a mapping relationship between the short-distance identification information of the UE and the network identifier of the UE.

 Specifically, in a case that the at least one UE that supports the UE is served by the first base station, the first base station generates paging information according to the at least one short-distance identification information of the at least one supporting UE that is carried in the first trigger message. Querying the message and sending the message to the proximity server, so that the proximity server receives the paging information query message, and obtains the short-distance identification information of the at least one supporting UE according to the paging information query message. At least one network identifier supporting the UE, and then transmitting the network identification information of the at least one supporting UE to the first base station.

 103. The first base station acquires, according to the network identifier of the at least one supporting UE, a paging moment of the at least one supporting UE.

Specifically, after acquiring the network identifier of the at least one supporting UE, the first base station may calculate, according to the network identifier of each of the at least one supporting UE, the paging formula to calculate the at least one supporting UE. Each of the paging moments supporting the UE is to calculate a PF (Paging Frame) and a P0 (Paging Occasion) of each of the at least one supporting UE. Specifically, when the network identifier of the at least one supporting UE is an IMSI, the base station calculates, by using a paging formula, a specific method for paging moments of each of the at least one supporting UE to support the UE:

First, the base station calculates the value of PF according to the formula 5Wmodr = ( )x(L3⁄4_/Z) modN), and the value of the SFN (System Frame Number) that satisfies the formula is the value of PF. The value of SFN is 0-1023; T is a parameter of DRX (Discontinuous Reception), which ranges from 32, 64, 128, 256; N=min (T, nB), nB The value ranges from 4Τ, 2Τ, Τ, Τ/2, Τ/4, Τ/8, Τ/16, Τ/32; [/E_/Z) = (/MS7)modl024, the IMSI (Internat iona 1 Mobi le Subscriber Ident I ty) is an international mobile subscriber identity that supports the UE. After calculating the PF supporting the UE, the base station according to the formula

Calculating the value of i-s of the supporting UE, where Ns has a value range of 1, 2, 4; floor is an algorithm that takes a smaller integer than UE_ID/N. Finally, the base station determines the value of P0 of the supporting UE according to a fixed mapping relationship between i_s and P0.

 It should be noted that, when the network identifier of the at least one supporting UE is S-TMSI, the base station may acquire the IMS I of the at least one supporting UE according to the S-TM SI of the at least one supporting UE, so that the IMS can be located in the IMS. I acquire at least one paging moment that supports the UE.

 The first base station sends a paging message to the at least one supporting UE according to the paging moment of the at least one supporting UE, where the paging message carries paging type identification information, to trigger the at least one supporting UE according to the The paging type identification information establishes a radio resource control RRC connection with the first base station.

 Specifically, after the base station calculates the paging moment of each of the supporting UEs in the at least one UE, the base station sends, according to the PF and P0 of each supporting UE in the at least one supporting UE, to each supporting UE in the at least one supporting UE. Paging message.

 It should be noted that the paging type identification information may indicate to the at least one supporting UE that only a DRB (Data Radio Bearer) is established, so that the at least one supporting UE establishes only the base station when establishing an RRC connection. The inter-DRB does not need to establish an EPS (Evolved Packet Sy st em) bearer with the base station.

The embodiment of the invention provides a paging method, where the first base station acquires the first trigger cancellation After the at least one UE that supports the UE, the network identifier of the at least one supporting UE is obtained according to the short-distance identification information of the at least one supporting UE that is carried in the first trigger message. And calculating, according to the obtained network identifier of the at least one supporting UE, a paging moment of the at least one supporting UE, and sending, according to the calculated paging moment, a paging message to the at least one supporting UE, to trigger the At least one of the supporting UEs establishes an RRC connection with the first base station. In this way, on the basis that there is no communication between the benefit UE and the server, the supporting UE can transmit or receive data by benefiting the UE, thereby improving the efficiency and user experience of the cooperative communication.

 The embodiment of the present invention provides a method for paging. As shown in FIG. 2, the method includes: 2 0 1. Supporting a user equipment UE receives a paging message sent by the first base station.

 The paging message carries the paging type identification information, where the paging message is sent by the first base station according to the obtained paging moment of the supporting UE, and the paging moment is the first base station. Obtaining, according to the network identifier of the supporting UE, the network identifier is obtained by the first base station according to the proximity identifier of the supporting UE.

 It should be noted that the UE in the embodiment of the present invention is in an idle state, that is, no RRC connection is established between the base station and the UE.

 Specifically, the first base station sends a paging message to the supporting user UE, and triggers the supporting UE to establish an RRC connection with the first base station, that is, the triggering support U E is changed from the idle state to the active state.

 It should be noted that the paging type identification information may indicate to the UE that the type of the RRC connection is established.

 The UE supports establishing a radio resource control RRC connection with the first base station according to the paging identity type information.

 Specifically, after the UE receives the paging message sent by the base station, the U E performs a process of establishing an RRC connection to establish a connection with the base station.

 Further, when the paging type identification information indicates that only the data radio bearer DRB is established, the supporting UE sends an RRC connection setup request message to the first base station, and the supporting UE establishes a relationship with the first base station. DRB.

The RRC connection setup request message carries the first identifier information. The first identifier information identifies that the establishment type of the RRC connection is that only the DRB is established. It should be noted that the paging type identification information indicates that only the data radio bearer is established.

In the case of the DRB, the specific steps of supporting the UE to establish an RRC connection with the first base station are as follows, including:

 51. The supporting UE sends an RRC connection setup request message to the first base station.

 The RRC connection setup request message carries the first identifier information.

 The first identifier information is used to identify that the establishment type of the RRC connection is to establish only the DRB.

 Specifically, the supporting UE establishes a corresponding RRC connection according to the paging type identification information. When the paging type identification information indicates that only the DRB is established, the first identification information carried in the RRC connection setup message sent by the supporting UE to the first base station needs to identify that the establishment type of the RRC connection includes establishing only the DRB.

 52. The supporting UE receives an RRC connection setup message sent by the first base station.

 53. The supporting UE sends an RRC connection setup complete message to the first base station.

 The non-access layer NAS (non-access layer) information is not carried in the RRC connection setup complete message.

 It should be noted that, by means of whether the RRC connection setup complete message carries the NAS information, it is used to indicate whether the base station establishes an EPS.

 It should be noted that, in this case, the UE and the base station only need to establish a DRB connection, and the EPS is not required to be established. Therefore, the RRC connection setup complete message does not carry the non-access stratum NAS information. If the UE and the base station need to establish a complete RRC connection, that is, the RRC connection setup complete message needs to carry the NAS information when the EPS connection needs to be established.

 54. The supporting UE receives the RRC connection reconfiguration information sent by the first base station.

 The RRC connection reconfiguration information carries DRB configuration information.

 It should be noted that, after receiving the RRC connection setup complete message sent by the supporting UE, the first base station performs corresponding DRB configuration for the RRC connection between the supporting UE and the first base station, and then passes the DRB configuration information. The RRC connection reconfiguration information is sent to the supporting UE, so that the supporting UE performs DRB configuration after receiving the RRC connection reconfiguration message.

 55. The supporting UE configures the DRB according to the DRB configuration information.

 56. The supporting UE sends an RRC connection reconfiguration complete message to the first base station.

The embodiment of the present invention provides a method for paging a message, and the user equipment UE is configured to receive a paging message sent by the first base station, and establish a radio resource control relationship with the first base station according to the paging identifier type information. RRC connection. In this way, when the UE is in an idle state, The base station triggers the UE to establish an RRC connection with the base station, so that the benefiting UE can send or receive data through the UE, so that the supporting UE can send or receive data through the benefiting UE, on the basis that there is no communication between the benefiting UE and the server. Improve the efficiency and user experience of collaborative communication.

 The embodiment of the invention provides a paging method, including:

 It is to be noted that, if the first base station stores the mapping relationship between the short-distance identification information of the UE and the network identifier of the UE, step 301-302 is performed; if the first base station does not store the short-distance identification information of the UE and the network of the UE For the mapping relationship between the identifiers, the other server stores the mapping relationship between the short-distance identification information of the UE and the network identifier of the UE. Steps 301-302 are not performed, and step 303a or step 303b is directly executed.

 301. The first base station acquires, by the at least one supporting UE or the network side device, a short-distance identifier of the at least one supporting UE and a network identifier of the at least one supporting UE.

 It should be noted that, when the at least one supporting UE enters the service range of the first base station, the at least one short-distance identifier of the supporting UE and the network identifier of the at least one supporting UE may be sent to the first base station. Alternatively, the network side device may send the network identifier of the UE and the short-distance identification information of the UE to the base station when the network identifier is allocated to the UE in the pairing process of the UE.

 It should be noted that the supporting UE is relatively in the same way as the benefiting UE. When one UE can transmit data through other UEs, the UE is a benefiting UE, and other UEs that perform data transmission on the UE are supported by the UE. UE.

 302. Update the first mapping information according to the proximity identifier of the at least one supporting UE and the network identifier of the at least one supporting UE.

 Specifically, the first base station, after acquiring the proximity identifier of the at least one supporting UE and the network identifier of the at least one supporting UE, the proximity identifier of the at least one supporting UE and the at least one supporting UE The network identifier is recorded in the first mapping information.

It should be noted that there may be two methods for the first base station to obtain the first trigger message, one is sent by the benefiting UE to the base station, and the other is sent by the second base station to the first base station, according to the first base station. The first method of triggering a message is different, and the steps performed below are different. If the first base station obtains the first trigger message, the benefiting UE sends the first base station to the first base station. If yes, step 303a is performed. If the first base station acquires the first trigger message and sends the first base station to the first base station, step 303b is performed. details as follows:

 303a. The first base station receives the first trigger message sent by the benefiting UE.

 The benefit UE is a UE served by the first base station.

 Specifically, the benefiting UE needs to use the supporting UE to transmit data, and the benefiting UE needs to obtain the short-distance identification information of the supporting UE, and then add the acquired short-distance identification information of the supporting UE to the first trigger message and send it to the first Base station. The first base station receives the benefiting UE and sends a first trigger message carrying the close-range user list information.

 It should be noted that the UE supporting the UE may find that its nearby UE can discover the capability of providing data transmission for other UEs, so the proximity server in the network allocates a close-range dedicated for close-range discovery to the supporting UE according to the request of supporting the UE. Identification information. The supporting UE broadcasts its own proximity identification information with some predefined rules so that other UEs can know their current location. At this time, the benefiting UE listens to the short-distance identification information sent by other surrounding UEs with a predefined rule. When the benefiting UE receives the short-distance identification information of the supporting UE that supports the UE broadcast, that is, to find that the supporting UE is within the close range of the beneficiary UE, the short-distance identification information supporting the UE is recorded at this time, so that the benefiting UE can obtain the support. The close-range identification information of the UE.

 303b. The first base station receives the first trigger message sent by the second base station.

 The second base station is another base station that requests the first base station to send a paging message to the supporting UE, except the first base station.

 Specifically, when the benefit UE is a UE served by the second base station, the benefit UE sends the first trigger message to a second base station serving the same, and then The first trigger message is sent to the first base station, so that the first base station initiates paging for supporting the UE.

It is to be noted that, after acquiring the first trigger message, the first base station may determine, according to the at least one short-distance identification information of the at least one supporting UE that is carried in the first trigger message, whether the at least one UE supporting the UE is a UE served by the base station. . If the at least one supporting UE is the UE served by the first base station, performing steps 304a, 305a, 306-308; or performing steps 304b, 305b, 306-308, as shown in FIG. 3 or FIG. If the at least one If the supporting UE is not the UE served by the first base station, the at least one supporting UE is the UE served by the neighboring base station, and step 304c is performed, as shown in FIG. 5.

 It should be noted that, in the embodiment of the present invention, the first base station needs to send a paging message to the at least one supporting UE in an idle state. At this time, the first base station needs to first determine at least one supporting UE in an idle state. The first base station may first determine at least one supporting UE in an idle state, and then acquire a network identity of at least one supporting UE that is idle. Of course, the first base station may also acquire the network identifiers of all the supporting UEs in the at least one support, and then determine at least one supporting UE in the idle state. The steps performed are different according to the timing at which the first base station determines that the at least one supporting UE in the idle state is different. If the base station first determines at least one supporting UE in the idle state, and then acquires the network identifier of the at least one supporting UE that is idle, steps 304a, 305a, 306-308 are performed. If the first base station first acquires the network identifiers of all the supporting UEs in the at least one support, and then determines at least one supporting UE in the idle state, steps 304b, 305b, and 306-308 are performed.

 The first base station determines, according to the short-distance identification information of the at least one supporting UE that is carried in the first trigger message, the at least one supporting UE that is in an idle state.

 Specifically, after acquiring the first triggering message, the first base station may determine, according to the at least one short-distance identification information of the at least one supporting UE that is carried in the first triggering message, which supporting UEs in the at least one supporting UE have been connected to the base station A service connection is established, which supports the UE not establishing a service connection with the first base station, so that at least one supporting UE in an idle state can be determined.

 It should be noted that the service connection established between the supporting UE and the base station is an RRC connection established between the supporting UE and the first base station.

 The first base station acquires the network identifier of the at least one supporting UE according to the short-distance identification information of the at least one supporting UE.

 Specifically, the base station may obtain the network identifier of the at least one supporting UE in two situations.

In the first case, as shown in FIG. 3, in a case where the first base station stores the mapping relationship between the at least one supporting UE's short-distance identification information and the network identifier, the first base station is configured according to the at least one in the idle state. Supporting close-range identification information of the UE, searching Pre-stored first mapping information, acquiring the network identifier of the at least one supporting UE in the idle state.

 The mapping between the short-distance identifier of the UE and the network identifier of the UE is recorded in the first mapping information.

 It should be noted that, if the first base station locally stores the mapping relationship between the short-distance identifier of the UE and the network identifier of the UE, the first base station needs to perform steps 301 and 302 to obtain the first mapping information.

 In the second case, as shown in FIG. 4, in a case where the first base station does not store the mapping relationship between the at least one supporting UE and the network identifier, the first base station according to the at least one supporting UE The proximity identifier information is obtained by the proximity server to obtain the network identifier of the at least one supporting UE.

 It should be noted that, when the first base station does not store the mapping relationship between the short-distance identifier of the UE and the network identifier of the UE, the first base station does not need to perform steps 301-302.

 304c, if the at least one supporting UE is a UE serving the third base station, the first base station sends, to the third base station, a paging message for paging the at least one supporting UE, so that the third base station receives the Obtaining, by the at least one paging message of the UE, the network identifier of the at least one supporting UE, and acquiring, according to the network identifier of the at least one supporting UE, a paging moment of the at least one supporting UE; Sending a paging message to the at least one supporting UE.

 The paging message of the at least one supporting UE carries the short-distance identification information of the at least one supporting UE.

 It should be noted that the third base station refers to other base stations that are in addition to the first base station and provide services for at least one supporting UE.

 Specifically, when the first base station determines that the at least one UE that supports the UE is not the UE it serves, the third base station that provides the service for the at least one supporting UE sends a message for paging the at least one supporting UE, so that the third base station performs the at least one supporting UE. Paging.

It should be noted that, in step 304c, the first base station is not at least one serving base station supporting the UE. When the first base station acquires the first trigger message, the step performed by the first base station is 303a, that is, the first base station does not store. a mapping relationship between the at least one short-distance identifier supporting the UE and the network identifier of the at least one supporting UE, that is, the first base station does not perform the step Step 3 0 3 0 2.

 It should be noted that, in step 3 04 c, the first base station is equivalent to the second base station in step 3 0 3 b . That is, after receiving the first trigger message sent by the benefiting UE, the first base station needs to send at least one support to the third base station serving the at least one supporting UE when detecting that at least one UE supporting the UE is not the UE it serves. UE message.

 It should be noted that, after the third base station receives the paging message sent by the first base station, at least one message that supports the UE, the processing procedure of the third base station and the first base station in the embodiment of the present invention receive the paging sent by the second base station. The processing after a message supporting the UE is the same, and will not be described here.

 The first base station acquires the network identifier of the at least one supporting UE in the idle state according to the short-distance identification information of the at least one supporting UE in the idle state.

 Specifically, the first base station, when determining the at least one supporting UE that is in the idle state, may learn, according to the at least one short-distance identification information of the supporting UE carried in the first trigger message, that the at least one supporting UE in the idle state is near The distance identification information, and then the network identifier of the at least one supporting UE in the idle state is obtained.

 Further, the base station may acquire the network identifier of the at least one supporting UE in the idle state.

Supporting the short-distance identification information of the UE, searching for the pre-stored first mapping information, and acquiring the network identifier of the at least one supporting UE in the idle state.

 The mapping between the short-distance identifier of the UE and the network identifier of the UE is recorded in the first mapping information.

 It should be noted that, if the first base station locally stores the mapping relationship between the short-distance identifier of the UE and the network identifier of the UE, the first base station needs to perform steps 3 0 1 and 3 0 2 to obtain the short-distance identifier of the UE. Mapping relationship between network identifiers of UEs.

In the second case, as shown in FIG. 4, in a case where the first base station does not store the mapping relationship between the at least one supporting UE and the network identifier, the first base station is configured according to the idle state. A close-range identification information supporting the UE, The proximity server acquires the network identifier of the at least one supporting UE in the idle state.

 It should be noted that, when the first base station does not store the mapping relationship between the short-distance identifier of the UE and the network identifier of the UE, the first base station does not need to perform steps 301-302.

 305b, the first base station is configured according to the at least one support carried in the first trigger message
