根据控制面协议构架，两个远端UE之间的无线资源控制(Radio Resource Control，RRC)信息和数据采用类似基于SRAP协议的中继传输方法。接收远端UE根据SRAP PDU携带的SRAP包头携带的无线承载指示，可以识别出RRC消息并进行相应的处理。According to the control plane protocol architecture, the Radio Resource Control (RRC) information and data between two remote UEs adopt a relay transmission method similar to that based on the SRAP protocol. The receiving remote UE can identify the RRC message and process it accordingly based on the radio bearer indication carried in the SRAP header carried by the SRAP PDU.

For example, in a discovery process, the relay UE may allocate the first target identifier to the first remote terminal after receiving the first remote terminal identifier. After the end UE requests forwarding of the discovery message, the identifier configured for the remote UE is carried in the response message of the discovery information subsequently sent to the remote UE.

After receiving the response discovery message, the relay UE forwards the response discovery message to the first remote UE, so that the first remote UE can learn that the relay terminal is Its assigned identifier.
或者，中继终端也可以直接向第一远端终端指示所述第一目标识别符，例如，中继终端可以利用旁链路无线资源控制(PC5RRC)信令流程向第一远端终端发送所述第一目标识别符，例如，在第一远端UE和中继UE建立中继旁链路过程中，中继UE通过PC5RRC信令配置第一远端UE的识别符。Alternatively, the relay terminal can also directly indicate the first target identifier to the first remote terminal. For example, the relay terminal can use the side link radio resource control (PC5RRC) signaling process to send the first target identifier to the first remote terminal. The first target identifier, for example, during the process of establishing a relay side link between the first remote UE and the relay UE, the relay UE configures the identifier of the first remote UE through PC5RRC signaling.
在本申请实施例中，第一中继终端在接收到第一远端终端发送的第一消息，第一中继终端可以在为第一远端终端转发第一消息前，为第一远端终端分配第一目标识别符。例如，接入中继UE在为远端UE生成转发消息时，可以为远端UE分配识别符。In this embodiment of the present application, after the first relay terminal receives the first message sent by the first remote terminal, the first relay terminal may forward the first message to the first remote terminal.

步骤3，所述第一中继终端根据所述至少一个第二候选识别符为所述第一远端终端分配第一目标识别符。Step 3: The first relay terminal allocates a first target identifier to the first remote terminal according to the at least one second candidate identifier.
例如，接入中继UE在为远端UE生成转发消息时，为远端UE选取1个或多个候选识别符，并把候选识别符添加到待转发的消息中。中间中继UE或对端远端UE在收到该消息时，从中得到候选识别符，并确定其中不可用的候选识别符。然后中间中继UE在进一步转发该消息时可以从中删除确定为不可用的候选识别符，然后把包含剩余候选识别符的消息转发出去，或者，也可以为不可用的候选识别符打不可用标记，并把包含了标记的候选识别符和剩余未打标记的识别符的消息转发出去。对端远端UE在收转发的消息后，将所述候选识别符信息包含在响应消息中发出去，该响应消息通过中间中继UE转发到接入中继UE，接入中继UE从响应消息携带的候选识别符中选择第一目标识别符分配给该远端UE。For example, when the access relay UE generates a forwarding message for the remote UE, it selects 1 for the remote UE. one or more candidate identifiers, and add the candidate identifiers to the message to be forwarded. When the intermediate relay UE or the opposite end remote UE receives the message, it obtains the candidate identifiers and determines the unavailable candidate identifiers therein. Then the intermediate relay UE can delete the candidate identifiers determined to be unavailable when further forwarding the message, and then forward the message containing the remaining candidate identifiers, or it can also mark the unavailable candidate identifiers as unavailable. , and forward the message containing the marked candidate identifiers and the remaining unmarked identifiers. After receiving the forwarded message, the opposite end remote UE includes the candidate identifier information in a response message and sends it. The response message is forwarded to the access relay UE through the intermediate relay UE, and the access relay UE responds from Select the first target identifier from the candidate identifiers carried in the message and assign it to the remote UE.
在一个可能的实现方式中，所述第一指示信息包括以下之一：In a possible implementation, the first indication information includes one of the following:
(1)第一识别符信息，所述第一识别符信息中包括所述至少一个第二候选识别符。例如，中间中继终端在接收到第一消息时，可以将第一消息中携带的至少一个第一候选识别符中的不可用的候选识别符删除，保留可用的候选识别符后转发第一消息，对端远端终端在接收到第一消息后，将第一消息中携带的至少一个第一候选识别符中的不可用的候选识别符删除，将剩余的可用的候选识别符携带在第一响应消息中发送。(1) First identifier information, the first identifier information includes the at least one second candidate identifier. For example, when receiving the first message, the intermediate relay terminal may delete the unavailable candidate identifiers among the at least one first candidate identifier carried in the first message, retain the available candidate identifiers, and forward the first message. , after receiving the first message, the opposite remote terminal deletes the unavailable candidate identifiers among the at least one first candidate identifier carried in the first message, and carries the remaining available candidate identifiers in the first message. Sent in response message.
(2)第二识别符信息，所述第二识别符信息中包括所述至少一个第一候选识别符和标记信息，所述标记信息用于标识所述至少一个第一候选识别符中的第一候选识别符是否可用。例如，中间中继终端在接收到第一消息时，可以标识第一消息中携带的至少一个第一候选识别符中的不可用的候选识别符，或标识第一消息中携带的至少一个第一候选识别符中的可用的候选识别符，转发携带所述至少一个候选标识符和标记信息的第一消息，对端远端终端在接收到第一消息后，如果确定未标记不可用的候选识别符中有不可用的，或者，确定标记可用的候选识别符中不可用的，则进一步进行标识，将标记后的至少一个候选识别符携带在第一响应消息中发送。(2) Second identifier information, the second identifier information includes the at least one first candidate identifier and mark information, the mark information is used to identify the third of the at least one first candidate identifier. Whether a candidate identifier is available. For example, when receiving the first message, the intermediate relay terminal may identify an unavailable candidate identifier among the at least one first candidate identifier carried in the first message, or identify at least one first candidate identifier carried in the first message. The available candidate identifiers among the candidate identifiers forward the first message carrying the at least one candidate identifier and marking information. After receiving the first message, the opposite end remote terminal determines that the unavailable candidate identifier is not marked. If any of the identified identifiers is unavailable, or if it is determined that the marked candidate identifiers are unavailable, then further identification is carried out, and at least one of the marked candidate identifiers is carried in the first response message and sent.
在一个可能的实现方式中，第一中继终端可以通过第一响应消息通知第一远端终端的第一目标识别符。因此，在该可能的实现方式中，所述第一中继终端根据所述至少一个第二候选识别符为所述第一远端终端分配第一目标识别符，可以包括以下步骤：In a possible implementation, the first relay terminal may notify the first target identifier of the first remote terminal through a first response message. Therefore, in this possible implementation, the first relay terminal allocates a first target identifier to the first remote terminal according to the at least one second candidate identifier, which may include the following steps:
步骤1，所述第一中继终端从所述至少一个第二候选识别符中选择一个可用的识别符分配给所述第一远端终端的第一目标识别符；Step 1: The first relay terminal selects an available identifier from the at least one second candidate identifier to assign to the first target identifier of the first remote terminal;
步骤2，所述第一中继终端向所述第一远端终端转发所述第一响应消息，在所述第一响应消息中指示分配给所述第一远端终端的第一目标识别符。Step 2: The first relay terminal forwards the first response message to the first remote terminal, indicating in the first response message the first target identifier assigned to the first remote terminal. .
采用上述可能的实现方式，为避免将远端UE的第一目标识别符通知对端远端UE的信令开销，可以预定义或预配置接入中继UE为远端UE确定的识别符为接收到的响应消息中包含的可用候选识别符中的某一个序号的识别符(例如第一个或最后一个)。这样对端远端UE在接收到响应消息后，可以确定远端UE的识别符，而不必要另行通知。因此，在一个可能的实现方式中，所述第一中继终端可以向所述第一远端终端转发所述第一响应消息，指示所述第一响应消息中携带的第一识别符信息中排在预定位置的第二候选识别符为分配给所述第一远端终端的第一目标识别符。Using the above possible implementation method, in order to avoid notifying the first target identifier of the remote UE to the peer The signaling overhead of the remote UE can be predefined or preconfigured. The identifier determined by the access relay UE for the remote UE is an identifier of a certain sequence number among the available candidate identifiers contained in the received response message ( e.g. first or last). In this way, after receiving the response message, the opposite remote UE can determine the identifier of the remote UE without further notification. Therefore, in a possible implementation, the first relay terminal may forward the first response message to the first remote terminal, indicating that the first identifier information carried in the first response message The second candidate identifier ranked at the predetermined position is the first target identifier assigned to the first remote terminal.
在一个可能的实现方式中，上述至少一个第一候选标识符可以由第一远端终端确定，例如，第一远端终端可以在发送的第一消息中携带至少一个候选识别符。因此，在该可能的实现方式中，在所述第一中继终端转发携带所述至少一个第一候选识别符的所述第一消息之前，所述方法还包括：所述第一中继终端从所述第一消息中获取所述至少一个第一候选识别符。In a possible implementation, the at least one first candidate identifier may be determined by the first remote terminal. For example, the first remote terminal may carry the at least one candidate identifier in the first message sent. Therefore, in this possible implementation, before the first relay terminal forwards the first message carrying the at least one first candidate identifier, the method further includes: the first relay terminal The at least one first candidate identifier is obtained from the first message.
在上述可能的实现方式中，第一远端终端还可以自己从第一响应消息中选择第一目标识别符，并通知第一中继终端，第一中继终端接收到该通知后，确定将第一目标识别符分配给第一远端终端。因此，可选地，所述第一中继终端根据所述至少一个第二候选识别符为所述第一远端终端分配第一目标识别符可以包括以下步骤：In the above possible implementation manner, the first remote terminal can also select the first target identifier from the first response message and notify the first relay terminal. After receiving the notification, the first relay terminal determines to The first target identifier is assigned to the first remote terminal. Therefore, optionally, the first relay terminal allocating a first target identifier to the first remote terminal according to the at least one second candidate identifier may include the following steps:
步骤1，所述第一中继终端向所述第一远端终端转发所述第一响应消息；Step 1: The first relay terminal forwards the first response message to the first remote terminal;
步骤2，所述第一中继终端接收所述第一远端终端发送的报告，其中，所述报告中携带有所述至少一个第二候选识别符中的一个识别符；Step 2: The first relay terminal receives a report sent by the first remote terminal, wherein the report carries one identifier of the at least one second candidate identifier;
步骤3，所述第一中继终端确定所述报告中携带的所述识别符作为分配给所述第一远端终端的第一目标识别符。Step 3: The first relay terminal determines the identifier carried in the report as the first target identifier assigned to the first remote terminal.
例如，远端UE自己确定候选识别符，并把候选识别符包含在消息中，在收到响应消息后，如果其中包含可用候选识别符，选取一个作为自身识别符并报告给接入中继UE，接入中继终端确定该识别符为分配给远端UE的识别符。For example, the remote UE determines the candidate identifier by itself and includes the candidate identifier in the message. After receiving the response message, if it contains available candidate identifiers, it selects one as its own identifier and reports it to the access relay UE. , the access relay terminal determines that the identifier is the identifier assigned to the remote UE.
在一个可能的实现方式中，第一中继终端携带在第一消息中的至少一个第一候选识别符经第一目标终端确定后可能均不可用，在这种情况下，第一中继终端需要重新选择至少一个第一候选识别符。因此，在该可能的实现方式中，在所述第一中继终端接收所述至少一个第一目标终端中一个或多个所述第一目标终端返回的第一响应消息之后，所述方法还可以包括：在所述第一响应消息中未携带有所述第一指示信息，或者，所述第一响应消息中携带的所述第一指示信息指示所述至少一个第一候选识别符均不可用的情况下，所述第一中继终端在所述第一消息中添加至少一个第三候选识别符后，转发携带所述至少一个第三候选识别符的所述第一消息，其中，所述至少一个第三候选识别符与所述至少一个第一候选识别符不相同。第一中继终端在转发携带所述至少一个第三候选识别符的所述第一消息，中间中继终端或对端终端的接入中继终端以及对端终端可以进一步确定所述至少一个第三候选识别符中的可用候选识别符，并在返回的第一发现响应消息中携带所述至少一个第三候选识别符中的可用候选识别符，第一中继终端在接收到该第一发现响应消息后，可以为第一远端终端分配第一目标识别符。In a possible implementation, at least one first candidate identifier carried by the first relay terminal in the first message may not be available after being determined by the first target terminal. In this case, the first relay terminal At least one first candidate identifier needs to be reselected. Therefore, in this possible implementation, after the first relay terminal receives the first response message returned by one or more of the at least one first target terminal, the method further It may include: the first indication information is not carried in the first response message, or the first indication information carried in the first response message indicates that none of the at least one first candidate identifier is available. If used, the first relay terminal adds at least one third candidate identifier to the first message, and then forwards The first message carrying the at least one third candidate identifier, wherein the at least one third candidate identifier is different from the at least one first candidate identifier. When the first relay terminal forwards the first message carrying the at least one third candidate identifier, the intermediate relay terminal or the access relay terminal of the opposite end terminal and the opposite end terminal may further determine the at least one third candidate identifier. The available candidate identifier among the three candidate identifiers, and the returned first discovery response message carries the available candidate identifier among the at least one third candidate identifier. The first relay terminal receives the first discovery After responding to the message, the first remote terminal may be assigned a first target identifier.
在一个可能的实现方式中，为了使得第一远端终端获知第二远端终端的识别符，第一响应消息中还可以携带所述第二远端终端的识别符。例如，第二远端终端在发送第一响应消息时，可以在第一响应消息中携带所述第二远端终端的识别符，或者，第二远端终端的接入中继终端在转发第一响应消息时，可以在第一响应消息中添加所述第二远端终端的识别符，然后转发携带所述第二远端终端的识别符的第一响应消息。In a possible implementation, in order for the first remote terminal to learn the identifier of the second remote terminal, the first response message may also carry the identifier of the second remote terminal. For example, when the second remote terminal sends the first response message, the second remote terminal may carry the identifier of the second remote terminal in the first response message, or the access relay terminal of the second remote terminal forwards the first response message. When receiving a response message, the identifier of the second remote terminal may be added to the first response message, and then the first response message carrying the identifier of the second remote terminal may be forwarded.
在本申请实施例中，一个中继UE同时也可以作为远端UE与另一个远端UE进行U2U通信，因此，中继UE可以分配识别符。为了使得第一目标终端可以获知第一中继终端的识别符，便于后续的路由路径的确定，因此，在一个可能的实现方式中，在所述第一中继终端转发所述第一消息之前，所述方法还包括：所述第一中继终端在所述第一消息中添加所述第一中继终端的识别符。In this embodiment of the present application, a relay UE can also act as a remote UE to perform U2U communication with another remote UE. Therefore, the relay UE can allocate an identifier. In order to enable the first target terminal to learn the identifier of the first relay terminal and facilitate subsequent determination of the routing path, in a possible implementation, before the first relay terminal forwards the first message , the method further includes: the first relay terminal adding the identifier of the first relay terminal to the first message.
另外，为了使得第一中继终端以及中间中继终端可以获知对端终端的接入中继终端的识别符，便于后续的路由路径的确定，因此，在一个可能的实现方式中，所述第一响应消息中还可以携带有第一目标中继终端的识别符，所述第一目标中继终端为所述第二远端终端的接入中继终端。例如，第二远端终端的接入中继终端(即第一目标中继终端)在转发第一响应消息时，可以在第一响应消息中添加所述第二远端终端的接入中继终端的识别符，然后转发携带所述第二远端终端的接入中继终端的识别符的第一响应消息。In addition, in order to enable the first relay terminal and the intermediate relay terminal to learn the identifier of the access relay terminal of the opposite terminal and facilitate subsequent determination of the routing path, in a possible implementation, the third relay terminal A response message may also carry an identifier of a first target relay terminal, and the first target relay terminal is the access relay terminal of the second remote terminal. For example, when forwarding the first response message, the access relay terminal of the second remote terminal (ie, the first target relay terminal) may add the access relay of the second remote terminal to the first response message. the identifier of the terminal, and then forwards the first response message carrying the identifier of the access relay terminal of the second remote terminal.
在一个可能的实现方式中，由于第一远端终端与第二远端终端之间可能存在多个中继通路，为了使得后续可以选择合适的中继通路，在所述第一中继终端转发所述第一消息之前，所述方法还包括：所述第一中继终端在所述第一消息中添加所述第一消息的延时信息，其中，所述延时信息包括以下至少之一：所述第一消息被转发的次数、所述第一消息经历的跳数、所述第一消息经历的时延信息。采用该可能的实现方式，第一消息中携带有第一消息的延时信息，从而使得在后续的流程中可以根据该延时信息，选择转发第一响应发消息的路径，或者转发中继消息的路径。In a possible implementation, since there may be multiple relay paths between the first remote terminal and the second remote terminal, in order to enable subsequent selection of an appropriate relay path, the first relay terminal forwards Before the first message, the method further includes: the first relay terminal adding delay information of the first message to the first message, wherein the delay information includes at least one of the following: : The number of times the first message has been forwarded, the number of hops experienced by the first message, and the delay information experienced by the first message. With this possible implementation, the first message carries the delay information of the first message, so that in the subsequent process, the path to forward the first response message can be selected based on the delay information, or the relay message can be forwarded. path of.
在本申请实施例还可以在U2U网络中设置一个远端UE识别符分配中继UE(可以称为识别符分配UE)，因此，在另一个可能的实现方式中，所述第一中继终端联合至少一个第一目标终端，为所述第一远端终端分配第一目标识别符，可以包括以下步骤：In the embodiment of this application, a remote UE identifier allocation relay UE (which may be called an identifier allocation UE) can also be set in the U2U network. Therefore, in another possible implementation, the first relay terminal Combining at least one first target terminal and allocating a first target identifier to the first remote terminal may include the following steps:
步骤1，所述第一中继终端向所述第一目标终端发送识别符分配请求，其中，所述识别符分配请求用于请求为所述第一远端终端分配识别符，所述第一目标终端为中继网络中用于分配识别符的终端；Step 1: The first relay terminal sends an identifier allocation request to the first target terminal, wherein the identifier allocation request is used to request the allocation of an identifier for the first remote terminal, and the first The target terminal is the terminal used to allocate identifiers in the relay network;
步骤2，所述第一中继终端接收所述第一目标终端返回的识别符分配响应消息，其中，所述识别符分配响应消息携带有所述第一目标终端为所述第一远端终端分配的第一目标识别符。Step 2: The first relay terminal receives an identifier allocation response message returned by the first target terminal, wherein the identifier allocation response message carries the first target terminal as the first remote terminal. The assigned first target identifier.
在一个可能的实现方式中，为了使得中继通路中的其它终端可以获知第一远端终端的识别符，在所述第一中继终端接收所述第一目标终端返回的识别符分配响应之后，所述方法还可以包括：所述第一中继终端在所述第一消息中添加所述第一目标识别符后，转发携带所述第一目标识别符的所述第一消息。In a possible implementation, in order to enable other terminals in the relay path to learn the identifier of the first remote terminal, after the first relay terminal receives the identifier allocation response returned by the first target terminal , the method may further include: after adding the first target identifier to the first message, the first relay terminal forwards the first message carrying the first target identifier.
例如，中继网络中存在一个远端UE识别符分配中继UE(可称为识别符分配UE)，当远端UE请求接入中继UE为其转发消息时，接入中继UE向识别符分配UE发起识别符分配请求，接入中继UE在从识别符分配UE获得识别符后，将识别符添加在转发的消息中转发出去，对端远端UE在收到转发消息时，从中获取远端UE的识别符，如果对端远端UE还未分配有识别符，则其接入中继UE通过类似的方法为其获取识别符分配。For example, there is a remote UE identifier allocation relay UE (which can be called the identifier allocation UE) in the relay network. When the remote UE requests the access relay UE to forward a message for it, the access relay UE sends a message to the identification allocation relay UE. The identifier allocating UE initiates an identifier allocation request. After obtaining the identifier from the identifier allocating UE, the access relay UE adds the identifier to the forwarded message and forwards it. When the opposite end remote UE receives the forwarded message, it Obtain the identifier of the remote UE. If the opposite remote UE has not been assigned an identifier, its access relay UE obtains the identifier assignment for it through a similar method.
在另一个可能的实现方式中，所述识别符分配请求还可以用于请求为第二远端终端分配识别符，所述第二远端终端为所述第一远端终端的对端终端，所述识别符分配响应还可以携带有所述第一目标终端为所述第二远端终端分配的第二目标识别符；所述第一中继终端转发的所述第一消息中还携带有所述第二目标识别符。In another possible implementation, the identifier allocation request may also be used to request the allocation of an identifier for a second remote terminal, and the second remote terminal is the counterpart terminal of the first remote terminal, The identifier allocation response may also carry the second target identifier allocated by the first target terminal to the second remote terminal; the first message forwarded by the first relay terminal also carries The second target identifier.
例如，一个接入中继UE为一个远端UE转发消息时，向识别符分配UE请求分配两个识别符，一个可以分配给远端UE，另一个可以作为候选识别符发送给对端远端UE，例如，中继UE可以把这远端UE的识别符和为对端远端UE申请的识别符包含在消息中，对端远端UE或对端远端UE的接入中继UE在收到该消息时，从中获取远端UE的识别符，如果此时对端远端UE未分配有识别符，则可将消息中携带的候选识别符作为对端远端UE的识别符。For example, when an access relay UE forwards a message to a remote UE, it requests the identifier allocation UE to allocate two identifiers. One can be allocated to the remote UE, and the other can be sent to the opposite remote terminal as a candidate identifier. UE, for example, the relay UE can include the identifier of the remote UE and the identifier applied for the opposite remote UE in the message. The opposite remote UE or the access relay UE of the opposite remote UE is in When the message is received, the identifier of the remote UE is obtained from it. If the opposite remote UE is not assigned an identifier at this time, the candidate identifier carried in the message can be used as the identifier of the opposite remote UE.
在一个可能的实现方式中，对端远端UE可能已经有识别符，为了使得第一中继终端获知该信息，在所述第一中继终端转发所述第一消息之后，所述方法还可以包括以下步骤：In a possible implementation, the opposite remote UE may already have an identifier. In order for the first relay terminal to learn the information, after the first relay terminal forwards the first message, the The method described above may also include the following steps:

Description of the method for assigning identifiers to remote terminals.
在本申请实施例中，远端终端的接入中继终端联合中间中继终端、对端远端终端的接入中继终端和对端远端终端为远端终端分配识别符主要包括以下步骤：In this embodiment of the present application, the access relay terminal of the remote terminal cooperates with the intermediate relay terminal, the access relay terminal of the opposite remote terminal, and the opposite remote terminal to allocate an identifier to the remote terminal, which mainly includes the following steps: :
步骤1、接入中继UE在为远端UE生成转发发现信号时，为远端UE选取1个或多个候选识别符，并把候选识别符添加到待转发的发现信号中转发。Step 1: When the access relay UE generates a forwarding discovery signal for the remote UE, it selects one or more candidate identifiers for the remote UE, and adds the candidate identifiers to the discovery signal to be forwarded for forwarding.
步骤2、中间中继UE、对端远端UE的接入中继UE或对端远端UE在接收到发现信号时，从中得到候选识别符，并确定其中不可用的候选识别符。Step 2: When the intermediate relay UE, the access relay UE of the opposite end remote UE or the opposite end remote UE receives the discovery signal, it obtains the candidate identifiers and determines the unavailable candidate identifiers therefrom.
其中，不可用的候选识别符可按如下一种或多种方法确定：Among them, unavailable candidate identifiers can be determined by one or more of the following methods:
(1)中间中继UE、对端远端UE的接入中继UE或对端远端UE确定当前该候选识别符正在被其它中继UE或远端UE使用；(1) The intermediate relay UE, the access relay UE of the opposite end remote UE or the opposite end remote UE determines that the candidate identifier is currently being used by other relay UEs or remote UEs;

步骤3、中间中继UE在进一步转发该发现信号前，对该发现信号中携带的候选识别符进行修改后转发。修改方式可以包括以下之一：1)从中删除确定为不可用的候选识别符，然后把包含剩余候选识别符的发现信号转发出去；2)为不可用的候选识别符添加不可用标记，并把包含了标记的候选识别符和剩余未打标记的候选识别符的发现信号转发出去。Step 3: Before further forwarding the discovery signal, the intermediate relay UE modifies the candidate identifier carried in the discovery signal and then forwards it. The modification method may include one of the following: 1) Delete the candidate identifiers determined to be unavailable, and then forward the discovery signal containing the remaining candidate identifiers; 2) Add an unavailable mark to the unavailable candidate identifiers, and The discovery signal containing the marked candidate identifiers and the remaining unmarked candidate identifiers is forwarded.
步骤4、对端远端UE在收转发的发现信号后，将所述候选识别符信息包含在响应发现信号中发出去。通过上述步骤，可以甄别出可用于分配的候选识别符。Step 4: After receiving the forwarded discovery signal, the opposite remote UE includes the candidate identifier information in the response discovery signal and sends it out. Through the above steps, candidate identifiers that can be used for allocation can be identified.
可选地，对端远端UE可以将自身的识别符包含在响应发现信号中，以便远端UE和/或远端UE的接入中继UE可以获得该对端远端UE的识别符。Optionally, the counterpart remote UE may include its own identifier in the response discovery signal, so that the remote UE and/or the access relay UE of the remote UE can obtain the identifier of the counterpart remote UE.

The candidate identifier is assigned to the peer remote UE.
步骤5、当接入中继UE收到的响应发现信号中没有候选识别符时，则重新为该UE选定一组候选识别符，重复上述步骤1至步骤4。Step 5: When there is no candidate identifier in the response discovery signal received by the access relay UE, a new set of candidate identifiers is selected for the UE, and the above steps 1 to 4 are repeated.
步骤6、当接入中继UE收到的响应发现信号时，其中包含至少一个候选识别符，接入中继UE从中选取一个识别符分配给远端UE。Step 6: When the access relay UE receives the response discovery signal, which contains at least one candidate identifier, the access relay UE selects an identifier from it and assigns it to the remote UE.
可选地，为避免将远端UE的识别符通知对端远端UE的信令开销，可以预定义或预配置接入中继UE为远端UE确定的识别符为收到的响应发现信号中包含的可用候选识别符中的某一个序号的识别符(例如第一个或最后一个)。这样对端远端UE在确定可用候选识别符时，就可以确定远端UE的识别符，不必要另行通知。Optionally, in order to avoid the signaling overhead of notifying the remote UE of the identifier of the remote UE, the identifier determined by the access relay UE for the remote UE may be predefined or preconfigured in response to the received discovery signal. The identifier of a certain sequence number (such as the first or last) among the available candidate identifiers contained in . In this way, when the opposite end remote UE determines the available candidate identifiers, it can determine the identifier of the remote UE without further notification.
可选地，上述过程中，远端UE的识别符也可以基于远端UE自己确定，远端UE自己确定候选识别符，并把候选识别符包含在发现信号中，在收到响应发现信号后，如果其中包含可用候选识别符，选取一个作为自身识别符并报告给接入中继UE。Optionally, in the above process, the identifier of the remote UE can also be determined based on the remote UE itself. The remote UE determines the candidate identifier by itself and includes the candidate identifier in the discovery signal. After receiving the response discovery signal , if it contains available candidate identifiers, select one as its own identifier and reported to the access relay UE.
可选地，接入中继UE也可以将自身的识别符包含在转发发现信号中发出去，对端远端UE的接入中继UE将自身的识别符包含在响应发现信号中发给接入中继UE。Optionally, the access relay UE may also include its own identifier in the forwarding discovery signal and send it, and the access relay UE of the opposite end remote UE may include its own identifier in the response discovery signal and send it to the receiving party. Enter the relay UE.
可选地，中继UE在转发发现信号时，将添加该发现信号经历的延时信息添加到转发发现信号中：Optionally, when forwarding the discovery signal, the relay UE adds the delay information experienced by the discovery signal to the forwarding discovery signal:
(1)发现信号被转发的次数或经历的跳数信息；(1) Discover the number of times the signal has been forwarded or the number of hops experienced;
(2)发现信号经历的时延信息(N毫秒)。(2) Discover the delay information experienced by the signal (N milliseconds).
下面以远端终端的接入中继终端联合识别符分配UE为远端终端分配识别符为例，对本申请实施例提供的远端终端的识别符的分配方法说明。The following takes the remote terminal's access relay terminal to jointly allocate the identifier with the UE to allocate the identifier to the remote terminal as an example to describe the method for allocating the identifier of the remote terminal provided by the embodiment of the present application.
在本申请实施列中，中继网络中存在一个远端UE识别符分配中继UE(可称为识别符分配UE)，当远端UE请求接入中继UE为其转发发现信号时，接入中继UE向识别符分配UE发起识别符分配请求，接入中继UE在获得识别符后，将识别符添加在转发的发现信号中转发出去，对端远端UE在收到转发发现信号时，从中获取远端UE的识别符，如果对端远端UE还未分配有识别符，则其接入中继UE通过类似的方法为其获取识别符分配。In the implementation of this application, there is a remote UE identifier allocation relay UE (which can be called the identifier allocation UE) in the relay network. When the remote UE requests access to the relay UE to forward the discovery signal for it, The incoming relay UE initiates an identifier allocation request to the identifier allocating UE. After obtaining the identifier, the access relay UE adds the identifier to the forwarded discovery signal and forwards it. The opposite remote UE receives the forwarded discovery signal. When, the identifier of the remote UE is obtained from it. If the opposite remote UE has not been assigned an identifier, its access relay UE obtains the identifier assignment for it through a similar method.
作为另一种改进方案，当一个接入中继UE为一个远端UE转发发现信号时，向识别符分配UE请求分配两个识别符，一个可以分配给远端UE，另一个可以作为候选识别符发送给对端远端UE，例如，中继UE可以把这远端UE的识别符和为对端远端UE申请的识别符包含在发现信号中，对端远端UE或对端远端UE的接入中继UE在收到该发现信号时，从中获取远端UE的识别符，如果此时对端远端UE未分配有识别符，则可将发现信号中携带的候选识别符作为对端远端UE的识别符，如果对端远端UE已经有识别符，则可以直接使用已有的识别符，也可以使用候选识别符与远端UE建立中继通路。对端远端UE在响应发现信号中，携带自身识别符。可选地，远端UE的接入中继UE在收到响应发现信号时，从中提取对端远端UE的识别符，如果对端远端UE的识别符不是所述候选识别符，可以通知识别符分配UE，释放候选识别符。As another improved solution, when an access relay UE forwards a discovery signal for a remote UE, the identifier allocation UE requests the allocation of two identifiers. One can be allocated to the remote UE and the other can be used as a candidate identifier. The identifier is sent to the opposite remote UE. For example, the relay UE can include the identifier of the remote UE and the identifier applied for the opposite remote UE in the discovery signal. The opposite remote UE or the opposite remote UE When the UE's access relay UE receives the discovery signal, it obtains the identifier of the remote UE. If the opposite remote UE is not assigned an identifier at this time, the candidate identifier carried in the discovery signal can be used as The identifier of the opposite remote UE. If the opposite remote UE already has an identifier, the existing identifier can be used directly, or a candidate identifier can be used to establish a relay path with the remote UE. The opposite end remote UE carries its own identifier in the response discovery signal. Optionally, when receiving the response discovery signal, the access relay UE of the remote UE extracts the identifier of the opposite remote UE from it. If the identifier of the opposite remote UE is not the candidate identifier, it may notify The identifier is assigned to the UE and the candidate identifier is released.
在本申请实施例中，该方法还可以包括：In the embodiment of this application, the method may also include:
(1)当一个接入中继UE释放与远端UE的中继旁链路时，通知识别符分配UE，释放分配给该远端UE的识别符。(1) When an access relay UE releases the relay side link with a remote UE, the identifier allocation UE is notified and the identifier allocated to the remote UE is released.
(2)当发现一个远端UE的识别符跟U2U网络中的一个其它远端UE的识别符相同时，任意中继UE可以向识别符分配UE报告识别符分配冲突。(2) When it is found that the identifier of a remote UE is the same as the identifier of another remote UE in the U2U network, any relay UE may report the identifier allocation conflict to the identifier allocating UE.
下面对本申请实施例中，两个远端UE之间的中继通路和路由的建立方案进行说明。The following is a description of the establishment method of the relay path and route between two remote UEs in the embodiment of the present application. case is explained.
一个中继UE在接收需要转发的发现信号时，可以执行以下操作：When a relay UE receives a discovery signal that needs to be forwarded, it can perform the following operations:
