The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof. It should be noted that, in the following embodiments, the first terminal may be a remote UE, and the second terminal may be a relay UE.

As shown in fig. 2, a flowchart of a communication method 200 provided in an exemplary embodiment of the present application, which may be executed by a first terminal, for example, by hardware and/or software installed in the first terminal, may include the following steps in the method 200.

S210, sending the second identifier to the second terminal.

The second identifier is generated according to the first information and is identifier information associated with the 5G-S-TMSI. The first information includes a first identifier and/or a predetermined identifier, where the first identifier is a real user identifier or a terminal identifier of the first terminal, such as 5G-S-TMSI, and the predetermined identifier is another identifier different from the first identifier.

In one implementation, a first Paging Occasion (PO) determined according to the first information is the same as a second paging occasion determined according to the second identifier; or the first paging occasion determined according to the first information is different from the second paging occasion determined according to the second identifier.

It should be noted that, in this embodiment, when receiving the second identifier, the second terminal may monitor, according to the second identifier, a paging message corresponding to the first terminal, such as a Radio Access Network paging message (RAN paging) and a Core Network (CN) paging, but cannot reversely push out the first information by using the second identifier, so that the second terminal may monitor the paging message of the first terminal while the first terminal does not expose a real user identifier or a terminal identifier, thereby effectively improving communication security in a wireless communication process.

In this case, the PO value calculated by the second terminal and the real PO value calculated by the terminal identifier or the user identifier (5G-S-TMSI) of the first terminal have a certain mapping relationship, where the first terminal and the first network side device both know the mapping relationship, and the second terminal does not know the mapping relationship, thereby effectively avoiding the problem of exposure of the terminal identifier or the identity identifier of the first terminal. In this embodiment, the first network side device may be a base station or the like.

In one implementation, referring to fig. 4 in combination, the process of the first terminal generating the second identifier according to the first information and the predetermined rule may include the following S310-S340. Assuming that the first identifier (terminal identifier, UE _ ID) is 5G-S-TMSI mod1024, an integer R1 is randomly generated, which has a value range of [ -UE _ ID/(N × Ns), (1024-UE _ ID)/(N × Ns)), N represents the total number of paging frames, and Ns represents the number of paging occasions on one paging frame.

S310, calculating P_seudo-ID1＝UE_ID+N*Ns*R1。

S320, judging P_seudoWhether ID1 is less than 1024.

S330, at P_seudoIn case ID1 is smaller than 1024, P will be_seudo-an ID as said second identity.

S340, at P_seudo-calculating P with ID1 not less than 1024_seudo-ID 2-UE _ ID-Ns R1, P_seudo-ID2 as said second identification.

It should be noted that the predetermined rule may be, but is not limited to, the rule described in the foregoing implementation manner. In addition, if the predetermined rule is configured in the first terminal and the first network-side device in advance, in order to ensure that the network-side and the terminal-side understand the same, the first terminal may send an instruction notification to the first network-side device to notify the first network-side device that the first terminal accesses the network through the second terminal. The indication notification may display an indication or an implicit indication, which is not limited in this embodiment.

And S320, sending the second identifier to the second terminal.

The implementation process of S320 may refer to the related description in the method 200, and is not described herein again to avoid repetition.

S330, sending the indication information to the first network side equipment.

The indication information is used for informing the first network side device to determine a second paging occasion according to the second identifier, so that the first network side device can page the first terminal at the second paging occasion, and the second terminal can correctly monitor the paging message of the first terminal.

As shown in fig. 5, a flowchart of a communication method 500 provided in an exemplary embodiment of the present application is shown, where the method 500 may be executed by a first terminal, for example, by hardware and/or software installed in the first terminal, and the method 500 may include the following steps.

S510, receiving a second paging message sent by the second terminal.

Wherein the second paging message (paging) corresponds to a third paging occasion, and the third paging occasion is determined according to the predetermined identifier. In one implementation, the second terminal calculates a third paging occasion (i.e., an initial paging occasion) according to a predetermined identifier (e.g., UE _ ID ═ 0), and then listens for a third paging message at the initial paging occasion and forwards the third paging message to the first terminal.

S520, the second identifier is sent to the second terminal.

S530, receiving a first paging message sent by the second terminal.

The first paging message corresponds to a second paging occasion, and the second paging occasion is determined according to the second identifier.

Illustratively, after receiving the second identifier, the second terminal calculates a second paging occasion according to the second identifier, monitors a first paging message corresponding to the first terminal at the second paging occasion, and forwards all the first paging messages monitored at the second paging occasion to the first terminal.

It can be understood that, while monitoring the first paging message corresponding to the first terminal, the second terminal may also monitor the paging message corresponding to itself. In addition, the second terminal may decode the paging message after monitoring the paging message, and forward the paging message to each terminal based on a correspondence between a terminal identifier (e.g., the second identifier) and a paging occasion.

Based on the foregoing

methods

200, 300, and 500, the following describes the implementation procedure of the communication method according to the present embodiment with reference to fig. 6.
