Referring to fig. 2, fig. 2 is a flowchart of a relay communication link processing method according to an embodiment of the present application. As shown in fig. 2, the relay communication link processing method includes the steps of:

Step 201: under the condition that a remote terminal has an emergency service or has a processing requirement of the emergency service, the remote terminal initiates a first operation corresponding to the emergency service, wherein the first operation is used for connecting the remote terminal with a relay terminal through a relay communication link of emergency service transmission;

The processing requirements of the remote terminal for having or having emergency services may include the following:

The remote terminal has emergency service arrival;

The remote terminal has the need of processing emergency services;

the remote terminal needs to perform an emergency service operation.

The first operation corresponding to the emergency service may be understood as an operation performed by the remote terminal in the case where the remote terminal has the emergency service or there is a processing requirement of the emergency service, and the relay communication link between the remote terminal and the relay terminal is a relay communication link for transmission of the non-emergency service. The purpose of this first operation is to connect the remote terminal with the relay terminal through a relay communication link of the emergency service transmission. That is, through the first operation, the relay communication link between the remote terminal and the relay terminal can be used for transmission of the emergency service.

In some embodiments, the remote terminal initiates a first operation corresponding to the emergency service, including any one of:

The remote terminal initiates a relay communication link reestablishment flow, and establishes a second relay communication link through the relay communication link reestablishment flow, wherein the second relay communication link is the relay communication link of the emergency service transmission;

And the remote terminal initiates a relay communication link updating flow and updates the first relay communication link into the relay communication link of the emergency service transmission through the relay communication link updating flow.

As an implementation manner, the remote terminal initiates the first operation may be that the remote terminal initiates the relay communication link reestablishment procedure, and establishes the second relay communication link through the relay communication link reestablishment procedure. The embodiment consists in re-establishing a relay communication link (i.e. a second relay communication link) for the emergency traffic transmission between the remote terminal and the relay terminal.

As another embodiment, the remote terminal initiating the first operation may be that the remote terminal initiates a relay communication link update procedure, and updates the first relay communication link to a relay communication link for emergency service transmission through the relay communication link update procedure. The embodiment consists in updating an original first relay communication link between the remote terminal and the relay terminal, such that the first relay communication link is updated to be a relay communication link for emergency traffic transmission, which is still the first relay communication link.

By means of any of the embodiments, transmission of emergency services through the relay communication link can be achieved, and normal transmission of emergency services in layer two relay communication can be ensured.

Optionally, before the remote terminal initiates the first operation corresponding to the emergency service, the remote terminal may perform discovery and/or selection of the relay UE using an emergency relay service code; and the discovery message corresponding to the discovery and/or selection of the relay UE carries an emergency relay service code.

Optionally, when the remote terminal uses the emergency relay service code to perform the selection of the relay UE, the relay UE corresponding to the first relay communication link may be preferentially selected; the discovery message also carries identification information of the relay UE corresponding to the first relay communication link. That is, when the selection of the relay UE is performed, the priority of the relay UE corresponding to the first relay communication link is higher.

Optionally, the remote terminal initiates a first operation corresponding to the emergency service, including the remote terminal performing the first operation based on the relay UE determined by discovery and/or selection of the relay UE. That is, it is determined by discovery and/or selection of relay UEs that the first operation is performed on a specific one or more relay UEs.

Optionally, before the remote terminal initiates the first operation corresponding to the emergency service, the method may further include: the remote terminal performs connection release to an access layer and/or a non-access layer. The connection release of the access layer and/or the non-access layer may include, for example, RRC local release, deregistration, and the like.

In some embodiments, the remote terminal initiates a relay communication link reestablishment procedure, and establishes a second relay communication link through the relay communication link reestablishment procedure, including:

the remote terminal sends an establishment request to the relay terminal, wherein the establishment request is used for requesting to establish a second relay communication link;

The remote terminal receives the establishment acceptance message from the relay terminal.

Optionally, the remote terminal initiates a relay communication link reestablishment procedure, and establishes a second relay communication link through the relay communication link reestablishment procedure, which may further include:

the remote terminal sends a release request to the relay terminal, wherein the release request is used for requesting to release the first relay communication link;

the remote terminal receives a release acceptance message from the relay terminal;

It should be noted that the above two steps are optional steps, and the remote terminal may or may not execute, or may determine whether to execute based on the specific implementation.

The first relay communication link comprises a PC5 unicast link between the remote terminal and the relay terminal, and the release request may be a request to release the PC5 unicast link between the remote terminal and the relay terminal, in which case the release request may be referred to as a PC5 unicast connection release request or a PC5 unicast link release request. Accordingly, the establishment request may be a request to establish a PC5 unicast link between the remote terminal and the relay terminal, in which case the establishment request may be referred to as a PC5 unicast connection establishment request or a PC5 unicast link establishment request.

The first relay communication link may include a communication link between the relay terminal and the network side device in addition to the PC5 unicast link between the remote terminal and the relay terminal. Here, the network-side device may be understood as a serving network element of the relay terminal, and may include a base station, and may further include an access and mobility management function (ACCESS AND Mobility Management Function, AMF) of the relay terminal (may be abbreviated as "relay AMF").

In this embodiment, when the remote terminal has an emergency service or there is a processing requirement of the emergency service, but the remote terminal is connected to the relay terminal through the relay communication link of the non-emergency service transmission, the remote terminal may send a release request to the relay terminal to release the relay communication link of the non-emergency service transmission. The relay terminal may transmit a release accept message to the remote terminal after receiving the release request. After receiving the release acceptance message, the remote terminal may send an establishment request to the relay terminal to request the relay terminal to establish a relay communication link for emergency service transmission. The relay terminal may send an establishment acceptance message to the remote terminal after receiving the establishment request.

The release request may carry first indication information, where the first indication information is used to indicate that the remote terminal has the emergency service or there is a processing requirement of the emergency service, and the first indication information may include at least one of the following:

Emergency service execution instruction information;

Emergency relay service codes (RELAY SERVICE codes);

Correspondingly, the establishment request may further carry second indication information, where the second indication information may include at least one of the following:

Emergency service execution instruction information;

an emergency relay service code;

emergency service cause value.

By the above process, the relay communication link (i.e., the second relay communication link) for the transmission of the emergency service can be established, so that the transmission of the emergency service through the relay communication link can be realized, and the normal transmission of the emergency service in the layer two relay communication can be ensured.

It should be noted that, the text of the PC5 unicast link of the second relay communication link may carry an emergency relay service code, so as to indicate that the second relay communication link is a relay communication link for transmitting emergency service.

In some embodiments, the remote terminal initiates a relay communication link update procedure and updates the first relay communication link to the relay communication link of the emergency service transmission through the relay communication link update procedure, including:

The remote terminal sends an update request to the relay terminal, wherein the update request is used for requesting to update the first relay communication link to the relay communication link of the emergency service transmission;

The remote terminal receives the update accept message from the relay terminal.

In this embodiment, when the remote terminal has an emergency service or there is a processing requirement of the emergency service, but the remote terminal is connected to the relay terminal through the relay communication link of the non-emergency service transmission, the remote terminal may send an update request to the relay terminal to update the relay communication link of the non-emergency service transmission to the relay communication link of the emergency service transmission. The relay terminal may transmit an update accept message to the remote terminal after receiving the update request.

The update request may further carry third indication information, where the third indication information may include at least one of the following:

Emergency service execution instruction information;

an emergency relay service code;

emergency service cause value.

Through the process, the first relay communication link can be updated, so that the transmission of the emergency service through the updated first relay communication link can be realized, and the normal transmission of the emergency service in the layer two relay communication can be ensured.

It should be noted that, the updated PC5 unicast link text of the first relay communication link may carry an emergency relay service code, so as to indicate that the updated first relay communication link is a relay communication link for emergency service transmission.

In addition, after the remote terminal completes the emergency service, the remote terminal may further perform at least one of the following:

initiating a relay communication link release procedure, and releasing a relay communication link (such as a second relay communication link or an updated first relay communication link) of the emergency service transmission through the relay communication link release procedure;
