[0094] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11 and a plurality of access devices 12.

[0095] UE 11 may refer to a device that provides voice and / or data connectivity to a user. UE 11 may communicate with one or more core networks via a Radio Access Network (RAN). UE 11 may be an IoT UE, such as a sensor device, a mobile phone (or a "cellular" phone), and a computer with an IoT UE. For example, it may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or user equipment (UE). Alternatively, UE 11 may be a device of an unmanned aerial vehicle.

Alternatively, the UE 11 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0096] The access device 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as a new generation radio access network (NG-RAN). Alternatively, an MTC system.

[0097] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) that adopts a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access device 12.

[0098] A wireless connection can be established between the access device 12 and the UE 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

The embodiments of this disclosure do not limit the implementation form of the core network element 13.

[0101] Referring to FIG2 , an embodiment of the present disclosure provides a process for UE-to-UE (U2U) relay discovery of proximity services. The proximity services in the present disclosure may include 5G proximity services. The process shown in FIG2 may include the following steps:

[0102] Step S21: The relay UE discovers one or more nearby UEs.

[0103] In an example of the present disclosure, the UE discovered by the relay UE may be a remote UE; for example, it may be a remote UE1 or a remote UE2.

[0104] In one example of the present disclosure, a 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.

[0105] In an example of the present disclosure, the relay UE obtains the UE identifier (User Info ID) corresponding to each relay service code (RSC).

[0106] Step S22: The relay UE sends an announcement message (UE-to-UE Relay Discovery Announcement message).

[0107] In one example of the present disclosure, 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 Info IDs of remote UEs.

[0108] In an example of the present disclosure, the announcement message may include a source Layer 2 (L2) ID and a destination L2 ID. The source L2 ID and the destination L2 ID are used for the UE corresponding to the source L2 ID to establish a communication connection with the destination L2 ID.

[0109] In one example of the present disclosure, the relay UE announces the User Info IDs of other neighboring UEs; when discovered, these UEs provide the relay UE with a relay indication, which is used to indicate whether the UE allows broadcasting of the UE's User Info ID.

[0110] In one example of the present disclosure, the remote UE monitors the announce message from the relay UE and can determine the destination L2 ID for signaling (eg, announce message) reception.

[0111] In the disclosed embodiment, the relay UE obtains the User Info ID of other nearby UEs through each RSC, which means that the relay UE needs to collect the target User Info ID, but also needs the RSC of the UE. When the RSC is lost, the relay UE does not know which RSC the remote UE is allowed to use.

[0112] As shown in FIG3 , an embodiment of the present disclosure provides a process for a UE to directly discover proximity services. The proximity services in the present disclosure may include 5G proximity services. The process shown in FIG3 may include the following steps:

[0113] Step S31: UE1 sends an announcement message. Optionally, the announcing UE (e.g., UE1) sends an announcement message, and the announcement message may include at least one of the following: the type of discovery message, a ProSe application code or a ProSe restricted code, a relay indication, a security protection element, and metadata information. Application layer metadata information may be included in the announcement message as metadata information. Optionally, UE1 may send the announcement message to at least one of UE2, UE3, UE4, and UE5. Optionally, the announcement message may include a destination L2 ID and a source L2 ID for sending the announcement message.

[0114] In one example of the present disclosure, if UE1 broadcasts its User Info ID during 5G proximity service discovery, the announcement message includes a relay indication.

[0115] As shown in FIG4 , an embodiment of the present disclosure provides a process for UE to directly discover proximity services. The proximity services in the present disclosure may include 5G proximity services. The process shown in FIG4 may include the following steps:

[0116] Step S41: UE1 sends a solicitation message.

[0117] In one example of the present disclosure, UE1 sends a request message. The request message may include at least one of the following: a discovery message type, a ProSe query code, a relay indication, and a security protection element. Optionally, UE1 may send the request message to at least one of UE2, UE3, UE4, and UE5. Optionally, the request message may include a destination L2 ID and a source L2 ID for the request message.

[0118] In an example of the present disclosure, UE1 determines a destination L2 ID for signaling (eg, announcement information) reception.

[0119] In one example of the present disclosure, if UE1 broadcasts its User Info ID during 5G proximity service discovery, the request message includes a relay indication.

[0120] Step S42: UE1 and / or UE2, etc. send response information. Optionally, UE2, UE3, UE4 and / or UE5 send response information; the response information is used to respond to the request information. Optionally, the response message includes at least one of the following: the type of discovery message, a proximity service response code (ProSe Response Code), a relay indication, a security protection element, and metadata information. The application layer metadata information may be included as metadata in the response message. Optionally, UE1 receives a response message sent by at least one of UE2, UE3, UE4 and UE5. Optionally, the response message may include the source L2 ID and the destination L2 ID of the response message.

[0121] In the above-described use case, during the Proximity Services Direct Discovery process, the announce message or request message only includes a relay indication to indicate whether the relay UE can broadcast its User Info ID during 5G Proximity Services U2U Discovery. However, the announce message or request does not include an RSC, meaning that no RSC is sent during the 5G Proximity Services Direct Discovery process. Therefore, a UE receiving the announce message or request message cannot be informed of which relay services are permitted by the UE sending the announce message or request message.

[0122] As shown in FIG5 , an embodiment of the present disclosure provides an information processing method, which is executed by a first UE and includes:

[0123] Step S51: Send first information, the first information at least including: a first identifier of a first UE, a second identifier of at least one second UE, and a first RSC corresponding to the first identifier; the first RSC is used to indicate a first relay service.

[0124] The first UE and the second UE involved in the embodiments of the present disclosure can be any mobile terminal or fixed terminal, etc.; for example, the first UE and the second UE can be at least one of the following: a mobile phone, a computer, a server, a wearable device, a game control platform, a roadside device, a vehicle-mounted device, a multimedia device, and an industrial device; for another example, the first UE and the second UE can be at least one of the following: an eMBB terminal, a reduced capability UE (Reduced capability UE), a Redcap terminal, and an extended Redcap (eRedcap) terminal.

[0125] In some embodiments, sending the first information in step S51 includes: sending the first information to at least one second UE. In the embodiments of the present disclosure, at least one may be one or more; and multiple may be two or more.

[0126] Optionally, the first UE may be a discoverer UE in U2U relay communication or U2N relay communication. Optionally, the first UE may be a source UE or a discoverer UE; the source UE or the discoverer UE includes a UE that sends the first information.

[0127] Optionally, the second UE is a relay UE or a remote UE in U2U relay communication. Exemplarily, in U2U relay communication, a sender UE, a relay UE, and / or a receiver UE are included; the second UE can be the relay UE and / or the receiver UE. The receiver UE is the remote UE.

[0128] Optionally, the second UE is a relay UE of U2N relay communication.

[0129] Optionally, the second UE is a target UE or a discovered UE. The target UE or the discovered UE refers to a UE that receives the first information.

[0130] In some embodiments, the UE corresponding to the second identifier is the UE that receives the first information. The second identifier includes an identifier of a destination address. In an embodiment of the present disclosure, the first UE may broadcast the first information to one or more destination addresses so that the first information is stored in the UE corresponding to the one or more destination addresses.

[0131] In some embodiments, the first relay service and the second relay service mentioned below may be services provided by UE-to-UE relay. The service may be any service, such as a conversation, video, and / or game-related service.

[0132] In some embodiments, the first RSC is used to indicate a first relay connection service. In the embodiment of the present disclosure, the second UE may determine a relay service to be executed based on the first RSC. For example, the first relay connection service may be a connection service provided by a UE-to-UE relay.

[0133] In some embodiments, one first RSC is used to indicate one relay service. Optionally, the first information may include at least one first RSC.

[0134] In some embodiments, the first identifier may be any number or index indicating the first UE. Optionally, the first identifier is a user information identifier (User Info ID). Optionally, the first identifier may be a Generic Public Subscription Identifier (GPSI) of the first UE or a Subscriber Permanent Identifier (SUPI) of the first UE.

[0135] In some embodiments, the second identifier may be any number or index indicating the second UE. Alternatively, the second identifier may be a destination ID. Alternatively, the second identifier may be the GPSI or SUPI of the second UE.

[0136] In some embodiments, the first identifier and the first RSC corresponding to the first identifier are used by the second UE to update and / or create the second information. Exemplarily, if the second UE is a relay UE for U2U relay communication, the first identifier and the first RSC corresponding to the first identifier are used by the second UE to create the second information or to update the second information. Exemplarily, if the second UE is a remote UE, the first identifier and the first RSC corresponding to the first identifier are used by the second UE to update the second UE.

[0137] In some embodiments, the first information may further include: a first L2 ID of the first UE and a second L2 ID of the second UE. The first L2 ID and the second L2 ID may be used for communication connection between the first UE and the second UE.

[0138] In an embodiment of the present disclosure, a first UE sends first information, which includes at least: a first identifier of the first UE, a second identifier of at least one second UE, and a first RSC corresponding to the first identifier; the first RSC is used to indicate a first relay service. This allows the UE receiving the first information to know which first RSC indicates the first relay service and which first UEs can execute which first relay services. This facilitates the subsequent execution of relay services between the first UE and the second UE.

[0139] In some embodiments, the first information further includes at least one of the following:

[0140] A relay indication, used to indicate whether the second UE is allowed to broadcast the first identifier;

[0141] Type indication, used to indicate the type of discovery message in relay communication.

[0142] Optionally, the relay indication is one of the following:

[0143] The first value is used to indicate that the second UE is not allowed to broadcast the first identifier;

[0144] The second value is used to indicate that the second UE is allowed to broadcast the first identifier;

[0145] The third value is used to indicate that the first identifier is allowed to be broadcasted through multiple hops.

[0146] Exemplarily, a first UE sends first information to a second UE, where the first information includes: a first identifier, a second identifier, a first RSC corresponding to the first identifier, and a relay indication. When the relay indication is a first value, such as "0" or empty, it is used to indicate that the second UE is not allowed to broadcast the first identifier; or, when the relay indication is a second value, such as "1", it is used to indicate that the second UE is allowed to broadcast the first identifier; or, when the relay indication is a third value, such as an integer greater than "1", it is used to indicate that the first identifier is allowed to be broadcast over multiple hops. For example, when the relay indication is "3", it indicates that the first identifier is allowed to be broadcast over 3 hops.

[0147] In an embodiment of the present disclosure, a relay indication can be used to indicate whether the first identifier of the first UE is allowed to be broadcast. In this way, the second UE receiving the first information can accurately know whether it is allowed to broadcast and discover the first identifier of the first UE, that is, the second UE can accurately know whether it is allowed to discover the first UE.

[0148] Optionally, the type indicator is one of the following:

[0149] A first type indication is used to indicate that the discovery message type is a direct discovery type;
