[0129] In some embodiments, 5G Proximity Service U2U Relay Discovery is applicable to 5G Proximity Service Layer 3 and Layer 2 U2U Relay Discovery for public safety use and commercial services. To perform 5G Proximity Service U2U Relay Discovery, the 5G Proximity Service remote UE and the 5G Proximity Service U2U Relay are pre-configured or equipped with relevant information.

[0130] In some embodiments, 5G Proximity Services U2U relay discovery uses RSCs, which indicate the connection services provided by the 5G Proximity Services U2U relay to 5G Proximity Services remote UEs. RSCs are pre-configured or provisioned on the 5G Proximity Services U2U relay and 5G Proximity Services UEs.

A 5G Proximity Services U2U relay that supports multiple RSCs uses multiple discovery messages to advertise the RSCs, with each discovery message carrying a single RSC.

[0131] FIG1B is a flow chart illustrating a U2U relay discovery process for proximity services according to an embodiment of the present disclosure. The proximity services in the present disclosure may include 5G proximity services. The process illustrated in FIG1B may include the following steps:

[0132] Step S1101: The relay UE discovers one or more nearby UEs.

[0133] Optionally, the UE discovered by the relay UE may be a remote UE; for example, it may be a remote UE1 or a remote UE2.

[0134] Optionally, the relay UE discovers other nearby UEs; for example, the relay UE may discover nearby UEs through a previous discovery or communication process. Exemplarily, the relay UE may discover one or more remote UEs by broadcasting a signal, or the relay UE may discover one or more remote UEs by receiving a signal sent by one or more remote UEs.

[0135] Optionally, the relay UE obtains the UE identifier (User Info ID) corresponding to each relay service code (Relay Service Code, RSC).

[0136] Step S1102: The relay UE sends an announcement message.

[0137] Optionally, the announcement message may be a U2U relay discovery announcement message (UE-to-UE Relay Discovery Announcement message).

[0138] Optionally, the announcement message may include the type of discovery message, a user information identifier (User Info ID) of the relay UE, an RSC, and a list of user information identifiers of remote UEs.

[0139] Optionally, the announcement message may include a source Layer 2 (Layer-2, L2) ID and a target L2 ID. The source L2 ID and the target L2 ID are used for the UE corresponding to the source L2 ID to establish a communication connection with the target L2 ID.

[0140] Optionally, the relay UE announces the user information identifiers of other neighboring UEs; when discovered, these UEs provide a relay indication to the relay UE, where the relay indication is used to indicate whether the UE is allowed to broadcast the user information identifier of the UE.

[0160] In the disclosed embodiment, the relay UE obtains the user identification information of other nearby UEs through each RSC. However, in step S1201 and / or step S1202, the user identification information and / or RSC are not included. Therefore, due to the lack of user identification information and / or RSC, the U2U relay cannot select the user identification information of UE1 and / or UE2, etc.
