Embodiment 1

[0078] In this embodiment, the initiator terminal device (initiator UE, or called the sender UE) carries an identifier update type indication in the PC5 unicast link identifier update request message, and the target terminal device (target UE) according to The identification update type indicates whether to update related identification information.

[0079] Such as figure 2 Shown, this embodiment comprises the following steps:

[0080] S202: There is an established PC5 unicast communication link between the initiator UE and the target UE.

[0081] S204: The initiator UE sends a PC5 unicast link identity update request message carrying an identity update type indication to the target UE. The above identity update type indication may include:

[0082] 1) Identity update triggered by privatization configuration; or

[0083] 2) Identity update triggered by non-privatization configuration. For example, the Layer 2 ID of the initiator UE conflicts or receives an ID update inst...

Embodiment 2

[0096] In this embodiment, the initiating UE selects whether to carry security information in the PC5 unicast link ID update request message, that is, the carrying of security information is equivalent to an indication for indicating that the target UE needs to update its own ID information. If the PC5 unicast link identifier update request message does not carry security information, the target UE determines whether to update its own identifier information according to the implementation of the terminal equipment (UE implementation).

[0097] Such as image 3 Shown, this embodiment comprises the following steps:

[0098] S302: There is an established PC5 unicast communication link between the initiator UE and the target UE.

[0099] S304: The initiator UE sends a PC5 unicast link identifier update request message carrying security information to the target UE.

[0100] S306: After receiving the PC5 unicast link identifier update request message, the target UE updates its ow...

Embodiment 3

[0110] In this embodiment, the initiator UE carries an information element of "identifier update required" in the PC5 unicast link identifier update request message, and the target UE determines whether to update relevant identifier information according to the identifier update requirement.

[0111] Such as Figure 4 Shown, this embodiment comprises the following steps:

[0112] S402: There is an established PC5 unicast communication link between the initiator UE and the target UE.

[0113] S404: The initiating UE sends a PC5 unicast link identifier update request message carrying "Identity Update Need" to the target UE. The above "Identity Update Need" may include:

[0114] 1) "identifier update required"; or

[0115] 2) "identifier update required".

[0116] S406: After receiving the PC5 unicast link identifier update request message, the target UE updates its own identifier information.

[0117] In this embodiment, it is assumed that the above information element of "i...

Abstract

The embodiment of the invention discloses an identifier updating method and equipment, and solves the problem that communication interruption is easily caused due to inconsistent understanding of triggering reasons of a PC5 unicast link identifier updating process by initiating end terminal equipment and target end terminal equipment. The method can be executed by the initiating end terminal equipment, and comprises the following steps: sending a PC5 unicast link identifier update request message, wherein under the condition that the PC5 unicast link identifier updating request message comprises indication information, the indication information is used for indicating whether the target terminal equipment updates the identifier or not.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to an identification updating method and device. Background technique [0002] The introduction of the PC5 unicast link identification update process is mainly to consider the privatization (privacy) issue of terminal equipment, and the purpose is to prevent the terminal equipment from being set by other terminal equipment or third-party equipment by updating the terminal equipment identification (for example, application layer identification). Don't and stalk. [0003] In related technologies, the triggering of the PC5 unicast link ID update process may not be caused by privatization issues. For example, the application layer temporarily indicates that the ID is updated, or the conflict of the layer 2 ID will trigger the PC5 unicast link ID update process. [0004] For the target terminal device, it cannot identify whether the process of updating the PC5 u...
