Description

Paging method, device and system

Technical Field

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

Background

With the rapid development of mobile communication technology, multi-user cooperative communication technology is developed. In the multi-User cooperative communication technology, a D2D (Device to Device communication) technology is used to realize communication between a terminal and a terminal, so that UEs (User equipments) can be supported by each other. In this way, the base station may first transmit data of a certain UE to other UEs in the vicinity of the UE (i.e., supporting UEs), and transmit the data to the UE (i.e., benefiting UEs) through a short-distance communication link between the supporting UEs and the UE.

In the process of establishing the communication link, on the network side, the user plane bearer on the core network side is established only in a manner of establishing a UE request for receiving and sending data. At the base station side, RBs (Radio Bearer) or partial RBs of multiple UEs need to be established according to information of multi-UE cooperative communication, so that downlink data can be sent to beneficial UEs through multiple RBs respectively.

In the multi-user cooperative communication technology, if beneficial UE needs to establish multi-user cooperative communication, a request message of the multi-user cooperative communication needs to be sent to a server serving the beneficial UE, so that the server sends the request message of the multi-user cooperative communication to a core network side, the core network side sends a paging message to supporting UE of the beneficial UE, and an RB bearer between the supporting UE and a base station is established. Therefore, when the beneficial UE establishes multi-user cooperative communication, the beneficial UE 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, unnecessary signaling interaction and supporting link establishment delay are increased, the cooperative communication efficiency is restricted, and finally the user experience is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

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

101. the first base station acquires a first trigger message.

The first trigger message carries short-distance identification information of at least one supporting User Equipment (UE).

Note that the short-range identification information of the UE is information for discovering and identifying the UE by other UEs in a short-range.

It should be noted that, supporting UEs and benefit UEs are relative, when one UE can transmit data through other UEs, the UE is the benefit UE, and the other UEs transmitting data to the UE are supporting UEs of the UE.

Specifically, there are two situations for the first base station to acquire the first trigger message according to the difference of the base stations serving the beneficial UE.

In a first case, the first base station receives a first trigger message sent by a benefit UE.

Wherein the beneficiating UE is a UE served by the first base station.

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

Specifically, if beneficial UE served by the first base station needs to transmit data by using surrounding UEs, the beneficial UE may obtain the short-distance identification information of the supporting UE in a monitoring manner, and then send a first trigger message carrying the short-distance identification information of the supporting UE to the first base station, so as to trigger the first base station to send a paging message to the supporting UE.

In the second case, the first base station receives a first trigger message sent by a second base station.

Wherein the second base station is other than the first base station, and requests the first base station to send a paging message to a supporting UE.

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

102. And if the at least one supporting UE is the UE serving 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, after acquiring the first trigger message, the first base station determines whether the UE served by the first base station exists in the supported UEs. If at least one supporting UE is a UE served by the first base station, the network identifier of the at least one supporting UE may be obtained according to the short-distance identifier 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 an IMSI (International Mobile Subscriber Identity) of the UE, or an S-TMSI (system architecture Evolution Mobile Subscriber Identity).

It should be noted that the network identifier of the UE may also be other identifiers that can uniquely identify the UE, which is not limited in the present invention.

Specifically, the first base station obtains the network identifier of the at least one supporting UE according to whether the first base station stores the mapping relationship between the network identifier of the at least one supporting UE and the short-distance identifier information.

In a first case, when the first base station stores the mapping relationship between the short-distance identification information of the at least one supporting UE and the network identifier, the first base station searches the pre-stored first mapping information according to the short-distance identification information of the at least one supporting UE, and obtains the network identifier of the at least one supporting UE.

Wherein, the first mapping information records the mapping relationship between the close range identifier of the UE and the network identifier of the UE.

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 short-range identifier and the network identifier of its serving UE, that is, has stored the first mapping information.

In a second case, when the first base station does not store the mapping relationship between the short-distance identification information of the at least one supporting UE and the network identifier, the first base station obtains the network identifier of the at least one supporting UE through the short-distance server according to the short-distance identification information of the at least one supporting UE.

The proximity server is a server storing a mapping relationship between the proximity identification information of the UE and the network identification of the UE.

Specifically, under the condition that the at least one supporting UE serves as a first base station, the first base station generates a paging information query message according to the short-distance identification information of the at least one supporting UE carried in the first trigger message, and sends the paging information query message to the short-distance server, so that after receiving the paging information query message, the short-distance server 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 in the paging information query message, and then sends the network identifier information of the at least one supporting UE to the first base station.

103. And the first base station acquires the paging time of the at least one supporting UE according to the network identifier of the at least one supporting UE.

Specifically, after obtaining 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, a Paging time of each of the at least one supporting UE by using a Paging formula, that is, calculate PF (Paging frame) and PO (Paging interference) of each of the at least one supporting UE.

Specifically, when the network identifier of the at least one supporting UE is the IMSI, the method for calculating, by the base station, the paging time of each supporting UE in the at least one supporting UE by using the paging formula is as follows:

first, the base station follows the formulaThe value of the PF is calculated, and the value of the SFN (System Frame Number) that satisfies the formula is the value of the PF. The value range of the SFN is 0-1023; t is a parameter of DRX (Discontinuous Reception mechanism), and the value ranges are 32, 64, 128 and 256; n = min (T, nB), nB is in the range of 4T, 2T, T, T/2, T/4, T/8, T/16 and T/32; UE _ ID = (IMSI) mod1024, which is an International Mobile Subscriber Identity (IMSI) that supports the UE. After the PF of the supporting UE is calculated, the base station calculates the value of i _ s of the supporting UE according to a formula i _ s = floor (UE _ ID/N) modNs, wherein the value range of Ns is 1, 2 and 4, and floor is an algorithm taking the largest integer smaller than UE _ ID/N. And finally, the base station determines the PO value of the supporting UE according to the fixed mapping relation between the i _ s and the PO.

It should be noted that, when the network identifier of the at least one supporting UE is S-TMSI, the base station may obtain the IMSI of the at least one supporting UE according to the S-TMSI of the at least one supporting UE, so as to obtain the paging time of the at least one supporting UE according to the IMSI.

104. And the first base station sends a paging message to the at least one supporting UE according to the paging time of the at least one supporting UE, wherein the paging message carries paging type identification information so as to trigger the at least one supporting UE to establish Radio Resource Control (RRC) connection with the first base station according to the paging type identification information.

Specifically, after calculating the paging time of each supporting UE of the at least one supporting UE, the base station sends a paging message to each supporting UE of the at least one supporting UE according to the PF and PO of each supporting UE of the at least one supporting UE.

It should be noted that the paging type identifier information may indicate to the at least one supporting UE to only establish a DRB (data Radio Bearer), so that when the at least one supporting UE establishes the RRC connection, only the DRB between the at least one supporting UE and the base station is established, and an EPS (Evolved Packet System) Bearer between the at least one supporting UE and the base station does not need to be established.

The embodiment of the invention provides a paging method, wherein after a first base station acquires a first trigger message, under the condition that at least one supporting UE serves the UE, a network identifier of the at least one supporting UE is acquired according to near-distance identifier information of the at least one supporting UE carried in the first trigger message, the paging time of the at least one supporting UE is calculated according to the acquired network identifier of the at least one supporting UE, and a paging message is sent to the at least one supporting UE according to the calculated paging time so as to trigger the at least one supporting UE to establish RRC connection with the first base station. Therefore, on the basis that no communication exists between the beneficial UE and the server, the supporting UE can send or receive data through the beneficial UE, and therefore the efficiency of cooperative communication and the user experience are improved.

An embodiment of the present invention provides a paging method, as shown in fig. 2, including:

201. and the supporting user equipment UE receives the paging message sent by the first base station.

The paging message carries paging type identification information, the paging message is sent by the first base station according to the obtained paging time of the supporting UE, the paging time is obtained by the first base station according to the network identification of the supporting UE, and the network identification is obtained by the first base station according to the short-distance identification of the supporting UE.

It should be noted that, in the embodiment of the present invention, the UE 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 to trigger the supporting user UE to establish an RRC connection with the first base station, that is, to trigger the supporting user UE to switch from an idle state to an active state.

It should be noted that the paging type identifier information may indicate the type of RRC connection establishment to the UE.

202. And the support UE establishes Radio Resource Control (RRC) connection with the first base station according to the paging identifier type information.

Specifically, after receiving the paging message sent by the base station, the UE performs a procedure of establishing an RRC connection, so as to establish a connection with the base station.

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

Wherein, the RRC connection establishment request message carries first identification information. The first identification information identifies the establishment type of the RRC connection as only establishing DRB.

It should be noted that, when the paging type identifier indicates to only establish the data radio bearer DRB, the specific step of supporting the UE to establish the RRC connection with the first base station includes:

s1, the support UE sends RRC connection establishment request information to the first base station.

Wherein, the RRC connection establishment request message carries first identification information.

The first identification information is used for identifying the establishment type of the RRC connection as only establishing the DRB.

Specifically, the support UE establishes a corresponding RRC connection according to the paging type identifier information. When the paging type identification information indicates that only the DRB is established, the first identification information carried in the RRC connection establishment message that supports the UE to send to the first base station needs to identify the establishment type of the RRC connection including only establishing the DRB.

S2, the support UE receives the RRC connection establishment message sent by the first base station.

And S3, the support UE sends an RRC connection setup completion message to the first base station.

Wherein, the RRC connection setup complete message does not carry Non-Access Stratum NAS (Non-Access Stratum) information.

It should be noted that, the NAS information is carried in the RRC connection setup complete message to indicate whether the base station establishes the EPS.

It should be noted that, in this case, only the DRB connection needs to be established between the UE and the base station, and the EPS does not need to be established, so the RRC connection setup complete message does not carry the NAS information in the non-access stratum. And if the UE and the base station need to establish complete RRC connection, namely the UE and the base station need to establish EPS connection in addition to DRB connection, the RRC connection establishment completion message needs to carry NAS information.

S4, the support UE receives the RRC connection reconfiguration information sent by the first base station.

Wherein, 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 on the RRC connection between the supporting UE and the first base station, and then sends DRB configuration information to the supporting UE through RRC connection reconfiguration information, so that the supporting UE performs DRB configuration after receiving the RRC connection reconfiguration message.

And S5, the support UE configures the DRB according to the DRB configuration information.

And S6, the support UE sends an RRC connection reconfiguration complete message to the first base station.

The embodiment of the invention provides a method for paging messages, which supports User Equipment (UE) to receive paging messages sent by a first base station and establishes Radio Resource Control (RRC) connection with the first base station according to paging identification type information. Therefore, when the UE is in an idle state, the base station triggers the UE to establish RRC connection with the base station, the beneficial UE can send or receive data through the UE, and on the basis that no communication exists between the beneficial UE and the server, the UE can be supported to send or receive data through the beneficial UE, so that the efficiency of cooperative communication and the user experience are improved.

The embodiment of the invention provides a paging method, which comprises the following steps:

it should be noted that, if the first base station stores the mapping relationship between the short-distance identification information of the UE and the network identification of the UE, step 301 and step 302 are executed; if the first base station does not store the mapping relationship between the short-range identity information of the UE and the network identity of the UE, but stores the mapping relationship between the short-range identity information of the UE and the network identity of the UE by another server, step 301 and step 302 are not executed, and step 303a or step 303b is directly executed.

301. And the first base station acquires the short-distance identification of the at least one supporting UE and the network identification of the at least one supporting UE through the at least one supporting UE or the network side equipment.

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

302. And updating the first mapping information according to the close range identification of the at least one supporting UE and the network identification of the at least one supporting UE.

Specifically, after acquiring the short-distance identifier of the at least one supporting UE and the network identifier of the at least one supporting UE, the first base station records the short-distance identifier of the at least one supporting UE and the network identifier of the at least one supporting UE into the first mapping information.

It should be noted that there may be two methods for the first base station to acquire the first trigger message, where one method is to transmit the first trigger message to the base station by the beneficiating UE, and the other method is to transmit the first trigger message to the second base station, and the following steps are performed differently according to different methods for the first trigger message acquired by the first base station. If the first base station acquires the first trigger message and the beneficial UE sends the first trigger message to the first base station, step 303a is executed, and if the first base station acquires the first trigger message and the beneficial UE sends the first trigger message to the first base station, step 303b is executed. The method comprises the following specific steps:

303a, the first base station receives the first trigger message sent by the benefit UE.

Wherein the beneficiating UE is a UE served by the first base station.

Specifically, the benefit UE needs to use the support UE to transmit data for the benefit UE, and then the benefit UE needs to acquire the short-distance identification information of the support UE first, and then add the acquired short-distance identification information of the support UE to the first trigger message to send to the first base station. The first base station receives a first trigger message which carries the short-distance user list information and is sent by the beneficial UE.

It should be noted that the supporting UE wants the UE in its vicinity to discover its capability of providing data transmission for other UEs, so the proximity server in the network allocates the proximity identification information dedicated for proximity discovery to the supporting UE according to the request of the supporting UE. The support UE broadcasts the close range identification information of the support UE outwards according to a certain predefined rule, so that other UEs can know the current position of the support UE. At this time, the benefit UE listens to the proximity identification information sent by other UEs in the surroundings according to a predefined rule. When the beneficial UE receives the short-distance identification information of the supporting UE broadcasted by the supporting UE, namely the short-distance identification information of the supporting UE is found to be in the short-distance range of the beneficial UE, the short-distance identification information of the supporting UE is recorded, so that the beneficial UE can acquire the short-distance identification information of the supporting UE.

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

It should be noted that, after the first base station acquires the first trigger message, it may determine whether the at least one supporting UE is a UE served by the base station according to the short-distance identification information of the at least one supporting UE carried in the first trigger message. If the at least one supporting UE is a UE served by the first base station, performing steps 304a, 305a, 306 and 308; or steps 304b, 305b, 306 and 308 are performed, as shown in FIG. 3 or FIG. 4. If the at least one supporting UE is not a UE served by the first base station, it indicates that the at least one supporting UE is a UE served by a neighboring base station, then 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 the idle state. At this time, the first base station needs to determine at least one supporting UE in an idle state. The first base station may determine at least one supporting UE in an idle state, and then acquire a network identifier of the at least one supporting UE in the idle state. Of course, the first base station may also obtain the network identifiers of all the supporting UEs in the at least one support first, and then determine the at least one supporting UE in the idle state. And according to different occasions when the first base station determines that at least one UE in an idle state is supported, different steps are executed. If the base station determines at least one supporting UE in the idle state first and then obtains the network identifier of the at least one supporting UE in the idle state, the steps 304a, 305a, and 306 are executed together with 308. If the first base station first obtains the network identities of all the supporting UEs in the at least one support and then determines the at least one supporting UE in the idle state, steps 304b, 305b, and 306 are performed together with step 308.

304a, the first base station determines at least one supporting UE in an idle state according to the short-distance identification information of the at least one supporting UE carried in the first trigger message.

Specifically, after the first base station obtains the first trigger message, it may determine, according to the close-range identification information of the at least one supporting UE carried in the first trigger message, which supporting UEs of the at least one supporting UE have established service connection with the base station, and which supporting UEs have not established service connection with the first base station, so as to determine the at least one supporting UE in an idle state.

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

304b, the first base station obtains the network identifier of the at least one supporting UE according to the short-distance identifier information of the at least one supporting UE.

Specifically, there may be two cases when the base station acquires the network identifier of the at least one supporting UE.

In a first case, referring to fig. 3, in a case that the first base station stores the mapping relationship between the short-distance identification information of the at least one supporting UE and the network identifier, the first base station searches the pre-stored first mapping information according to the short-distance identification information of the at least one supporting UE in the idle state, and obtains the network identifier of the at least one supporting UE in the idle state.

It should be noted that, if the first base station locally stores the mapping relationship between the short-range 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 a second case, referring to fig. 4, in a case that the first base station does not store the mapping relationship between the short-distance identification information of the at least one supporting UE and the network identifier, the first base station obtains the network identifier of the at least one supporting UE through the short-distance server according to the short-distance identification information 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-range identity of the UE and the network identity of the UE, the first base station does not need to perform step 301-302.

304c, if the at least one supporting UE is a UE serving a third base station, the first base station sends a paging message for paging the at least one supporting UE to the third base station, so that after the third base station receives the paging message for the at least one supporting UE, the network identifier of the at least one supporting UE is obtained, and according to the network identifier of the at least one supporting UE, the paging time of the at least one supporting UE is obtained; and sending a paging message to the at least one supporting UE according to the paging time.

The paging message for paging 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 is another base station, besides the first base station, that provides a service for at least one supporting UE.

Specifically, when the first base station determines that the at least one supporting UE is not the UE served by the first base station, the first base station sends a message for paging the at least one supporting UE to a third base station serving the at least one supporting UE, so that the third base station pages the at least one supporting UE.

It should be noted that, in step 304c, the first base station is not a serving base station supporting at least one UE, and the step 303a is executed when the first base station acquires the first trigger message, that is, the first base station does not store the mapping relationship between the short-range identifier of the at least one supporting UE and the network identifier of the at least one supporting UE, that is, the first base station does not execute step 301 and step 302.

In step 304c, the first base station corresponds to the second base station in step 303 b. That is, after receiving the first trigger message sent by the benefit UE, the first base station needs to send a message for paging the at least one supporting UE to the third base station serving the at least one supporting UE when detecting that the at least one supporting UE is not the UE served by the first base station.

It should be noted that, after the third base station receives the message for paging the at least one supporting UE sent by the first base station, a processing procedure of the third base station is the same as the processing procedure after the first base station receives the message for paging the at least one supporting UE sent by the second base station in the embodiment of the present invention, and details are not repeated here.

305a, the first base station acquires the network identifier of the at least one supporting UE in the idle state according to the close-range identifier information of the at least one supporting UE in the idle state.

Specifically, when determining the at least one supporting UE in the idle state, the first base station may learn, according to the close-range identification information of the at least one supporting UE carried in the first trigger message, the close-range identification information of the at least one supporting UE in the idle state, and then acquire the network identification of the at least one supporting UE in the idle state.

Further, there may be two cases when the base station acquires the network identifier of the at least one supporting UE in the idle state.

It should be noted that, if the first base station locally stores the mapping relationship between the short-range 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 mapping relationship between the short-range identifier of the UE and the network identifier of the UE.

In a second case, referring to fig. 4, in a case that the first base station does not store the mapping relationship between the short-distance identification information of the at least one supporting UE and the network identifier, the first base station obtains, through the short-distance server, 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.

305b, the first base station determines at least one supporting UE in an idle state according to the short-distance identification information of the at least one supporting UE carried in the first trigger message.

Specifically, refer to step 304a, which is not described herein again.

It should be noted that, after the first base station determines the at least one supporting UE in the idle state, since the first base station already acquires the network identifier of the at least one supporting UE in step 304b, at this time, the first base station may find the network identifier of the at least one supporting UE in the idle state from the network identifier of the at least one supporting UE acquired.

306. And the first base station acquires the paging time of the at least one supporting UE in the idle state according to the network identifier of the at least one supporting UE in the idle state.

Specifically, after acquiring the network identifier of the at least one supporting UE in the idle state, the base station may calculate the paging time of the at least one supporting UE in the idle state by using a paging formula according to the network identifier of the at least one supporting UE in the idle state.

Specifically, refer to step 103, which is not described herein.

307. And the first base station sends a paging message to the at least one supporting UE in the idle state according to the paging time of the at least one supporting UE in the idle state so as to trigger the at least one supporting UE in the idle state to establish RRC connection with the first base station. And the support UE receives the paging message.

Specifically, after calculating the paging time of at least one supporting UE in an idle state, the base station sends a paging message to the at least one supporting UE in the idle state according to the paging time, and the supporting UE receives the paging message.

Specifically, refer to step 104 and step 201, which are not described herein again.

308. And the support UE establishes Radio Resource Control (RRC) connection with the first base station according to the paging identifier type information.

Further, when the paging type identifier indicates to only establish the data radio bearer DRB, refer to S1-S6 in step 202 for the step of establishing the RRC connection between the base station and the UE, which is not described herein again.

It should be noted that, when the paging type identifier indicates to only establish the data radio bearer DRB, the method further includes the step of the first base station establishing a mapping relationship between the DRB and the evolved packet system EPS bearer of the beneficial UE or the beneficial UE of the second base station.

The beneficial UE of the second base station is a UE that can send a paging message carrying the short-range identification information of the at least one supporting UE to the second base station, among UEs served by the second base station.

Specifically, when the benefited UE is the UE served by the first base station, the first base station sets a mapping relationship between the DRB between the at least one support UE and the first base station and the EPS between the benefited UE and the first base station, so that the benefited UE can receive data that needs to be sent to the benefited UE through the support UE.

Specifically, when the benefited UE is the UE served by the second base station, the first base station needs to map the DRB between the supporting UE and the first base station to the X2 port between the first base station and the second base station. The second base station needs to map the EPS between the benefited UE served by the second base station and the second base station to an X2 port between the second base station and the first base station. So that the first base station can establish a mapping relationship between the DRB and an EPS bearer of the beneficiary UE through an X2 interface between the first base station and the second base station, so that the beneficiary UE can receive data required to be sent to the beneficiary UE through the supporting UE.

The embodiment of the invention provides a paging method, wherein after a first base station acquires a first trigger message, under the condition that at least one supporting UE serves the UE, a network identifier of at least one supporting UE is acquired according to near-distance identifier information of the at least one supporting UE carried in the first trigger message, the paging time of the at least one supporting UE is acquired according to the acquired network identifier of the at least one supporting UE, and then the paging message is sent to the at least one supporting UE according to the calculated paging time to trigger the at least one supporting UE to establish RRC connection with the first base station. Therefore, on the basis that no communication exists between the beneficial UE and the server, the supporting UE can send or receive data through the beneficial UE, and therefore the efficiency of cooperative communication and the user experience are improved.

In a first case, the obtaining unit 601 is specifically configured to search, according to the close-range identification information of the at least one supporting UE, first mapping information stored in advance, and obtain a network identifier of the at least one supporting UE.

It should be noted that, in this case, the obtaining unit 601 of the first base station has previously obtained and stored the mapping relationship between the short-range identifier and the network identifier of its serving UE, that is, has stored the first mapping information, before obtaining the first trigger message.

In a second case, the obtaining unit 601 obtains the network identifier of the at least one supporting UE through the proximity server specifically according to the proximity identifier information of the at least one supporting UE. The proximity server is a server storing a mapping relationship between the proximity identification information of the UE and the network identification of the UE.

The value range of the SFN is 0-1023; t is a parameter of DRX (Discontinuous Reception mechanism), and the value ranges are 32, 64, 128 and 256; n = min (T, nB), nB is in the range of 4T, 2T, T, T/2, T/4, T/8, T/16 and T/32; UE _ ID = (IMSI) mod1024, which is an International Mobile Subscriber Identity (IMSI) that supports the UE.After the PF of the supporting UE is calculated, the base station calculates the value of the output i _ s of the supporting UE according to a formula i _ s = floor (UE _ ID/N) modNs, wherein the value range of Ns is 1, 2 and 4, and floor is an algorithm which takes the largest integer smaller than UE _ ID/N. Finally, the obtaining unit 601 determines the value of the outgoing PO of the supporting UE according to the fixed mapping relationship between i _ s and PO.

It should be noted that, when the network identifier of the at least one supporting UE is S-TMSI, the obtaining unit 601 may obtain the IMSI of the at least one supporting UE according to the S-TMSI of the at least one supporting UE, so as to obtain the paging time of the at least one supporting UE according to the IMSI.

As shown in fig. 10, the base station further includes: an update unit 607.

At this time, the obtaining unit 601 is further configured to obtain, through the at least one supporting UE or the network-side device, the short-distance identifier of the at least one supporting UE and the network identifier of the at least one supporting UE.

the processor 1204 is configured to obtain a first trigger message.

Specifically, there are two situations for the processor 1204 to acquire the first trigger message according to the difference of the base stations serving the beneficial UE.

In a first case, the processor 1204 is specifically configured to receive a first trigger message sent by a benefit UE.

Wherein the beneficiating UE is a UE served by the first base station.

In the second case, the processor 1204 is specifically configured to receive a first trigger message sent by the second base station.

In a first case, the processor 1204 is specifically configured to search, according to the short-distance identification information of the at least one supporting UE, first mapping information stored in advance, and obtain a network identifier of the at least one supporting UE.

It should be noted that, in this case, the processor 1204 of the first base station has previously acquired and stored the mapping relationship between the short-range identifier and the network identifier of its serving UE, that is, has stored the first mapping information, before acquiring the first trigger message.

In a second case, the processor 1204 obtains the network identifier of the at least one supporting UE through a proximity server specifically according to the proximity identifier information of the at least one supporting UE.

The processor 1204 is further configured to obtain a paging occasion of the at least one supporting UE according to the network identifier of the at least one supporting UE.
