Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative work, all belong to the scope of protection of this application.

The following is a brief description of several communication technologies in this field:

(1) Cellular network communication

As shown in Figure 1, the cellular network communication mode, that is, the terminal and the network device transmit uplink and downlink data/control information through the Uu interface.

The processing method of Uu interface reconfiguration failure in the cellular network is as follows:

If the terminal is in the Evolved Universal Terrestrial Radio Access (E-UTRA) master cell group (Master Cell Group, MCG), the new air interface (New Radio, NR) is the secondary cell group (Secondary Cell Group), SCG) dual connectivity (E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR, EN-DC) status:

If the terminal cannot process the radio resource control (Radio Resource Control, RRC) reconfiguration message carried by the Signaling Radio Bearer (Signalling Radio Bearer, SRB) 3, it will continue to use the configuration used before receiving the RRC reconfiguration message. At this time, if the master cell group (Master Cell Group, MCG) transmission is not suspended, the secondary cell group (Secondary Cell Group, SCG) failure process will be initiated after the reconfiguration process, and the SCG configuration error will be reported; if the MCG transmission is suspended , then the reconfiguration process ends and the connection re-establishment process (LTE connection re-establishment process) is initiated.

If the terminal cannot process the RRC reconfiguration message carried by SRB1, it will continue to use the configuration used before receiving the RRC reconfiguration message, and initiate a connection re-establishment process after the reconfiguration process ends.

If the terminal receives RRC reconfiguration from NR, such as NR standalone, NR-E-UTRA Dual Connectivity (NE-DC) or NR-NR Dual Connectivity (NR NR Dual Connectivity , NR-DC):

If the terminal cannot process the RRC reconfiguration message carried by SRB3, it continues to use the configuration used before receiving the RRC reconfiguration message. At this time, if the MCG transmission is not suspended, the SCG failure process is initiated after the reconfiguration process is completed to report the SCG configuration error; if the MCG transmission is suspended, the reconfiguration process ends and the connection re-establishment process (NR connection re-establishment process) is initiated.

If the terminal cannot process the RRC reconfiguration message carried by SRB1 or the high layer indicates that the non-access stratum container (nas-container) is invalid, continue to use the configuration used before the RRC reconfiguration message is received, and perform the following operations:

If the access layer (Access Stratum, AS) security is not activated, the UE enters the RRC idle state (RRC_IDLE), and the release cause is set to "other" (that is, the release cause is set to "other");

If AS security has been activated, but SRB2 and Data Radio Bearer (DRB) have not been established, the UE enters RRC_IDLE, and the release cause is set to RRC connection failure (that is, the release cause is set to "RRC connection failure");

In other cases, the UE initiates RRC re-establishment after the RRC reconfiguration process ends.

(2) Direct communication

As shown in FIG. 2 , direct communication refers to a manner in which adjacent terminals can perform data transmission through a direct communication link (also called Sidelink or PC5) within a short distance. The wireless interface corresponding to the Sidelink link is called a direct communication interface (also called a Sidelink interface or a PC5 interface).

(3) Relay

As shown in Figure 3, for UE-to-Network Relay, the interface between the relay terminal and the network device uses the Uu interface, and the interface between the relay terminal and the relayed terminal (or remote terminal) uses direct communication Interface (also known as Sidelink interface, or bypass interface, or PC5 interface). The link (Uu link) between the relay and the network may be called a backhaul link (Backhaul link or Uu backhaul link) for the remote terminal.

Among them, the method and the device (or terminal) are conceived based on the same application. Since the principles of the method and the device (or terminal) to solve problems are similar, the implementation of the device (or terminal) and the method can be referred to each other, and the repetitions will not be repeated. .

As shown in FIG. 4 , an embodiment of the present disclosure provides a method for processing reconfiguration failure, which is applied to a relay terminal, and the method includes:

Optionally, when the relay terminal determines that the reconfiguration of the direct communication interface from the relay terminal to the remote terminal fails, the relay terminal may continue to use the direct communication interface used before the direct communication interface reconfiguration configuration, and send the first indication information to the remote terminal.

Optionally, the first indication information may be carried by PC5-S (PC5-Signaling) signaling or PC5-RRC signaling.

In this embodiment, when the relay terminal determines that the reconfiguration fails, the relay terminal sends to the remote terminal first indication information for triggering the remote terminal to select and/or reselect a target object, so as to When the reconfiguration fails, the remote terminal is triggered to select and/or reselect the target object to ensure that the system can operate normally after the reconfiguration fails in the relay scenario; and/or, the relay terminal determines the reconfiguration When it fails, the relay terminal sends to the network device second indication information for indicating the relevant parameters of the reconfiguration failure, so that the network device can learn the relevant parameters of the reconfiguration failure, so as to perform relevant processing, so as to ensure that After the reconfiguration fails in the following scenarios, the system can operate normally.

Specifically, if the relay terminal determines that the reconfiguration of the relay terminal on the Uu interface fails, the behavior of the relay terminal may adopt one of the following methods:

Mode 1: The relay terminal sends first indication information to the remote terminal, where the first indication information is used to trigger the remote terminal to select and/or reselect a target object, where the target object includes a cell and/or Relay terminal.

The remote terminal determines a target relay terminal and/or a target cell according to the first indication information.

Specifically, once the remote terminal is triggered to select and/or reselect a target object, the remote terminal may initiate RRC establishment and/or RRC re-establishment through the determined target object. For example: the remote terminal may be triggered to perform at least any of the following: cell selection and/or relay terminal selection; cell selection and/or relay terminal reselection; cell reselection and/or relay terminal selection; Cell reselection and/or relay terminal reselection.

Embodiment 1: The relay terminal fails to reconfigure on the Uu interface; as shown in Figure 8, the method includes:

Step 81: the network device sends an RRC reconfiguration (Reconfiguration) message to the relay terminal through the Uu interface;

Taking the NR system as an example, the RRC reconfiguration process may use the RRCReconfiguration message.

Step 82: The relay terminal judges that the reconfiguration of the relay terminal on the Uu interface fails;

Specifically, if the relay terminal cannot interpret part of the information in the RRC reconfiguration message received by the Uu interface, it may be determined that the relay terminal fails to reconfigure on the Uu interface.

Step 83: the relay terminal sends the first indication information to the remote terminal;

Specifically, once the relay terminal determines that the reconfiguration of the relay terminal on the Uu interface fails, the relay terminal behaves as follows:

If AS security has been activated, but SRB2 and DRB have not been established, the UE enters RRC_IDLE, and the release cause is set to "RRC connection failure";

In addition, the relay terminal also needs to send first indication information to the remote terminal, where the first indication information is used to trigger the remote terminal to perform target object selection and/or reselection; wherein the target object includes a cell and/or or relay terminals.

Optionally, the first indication information may be carried by PC5-S signaling (such as PC5-S connection release signaling) or PC5-RRC signaling (such as PC5-RRC connection release signaling).

Step 84: the remote terminal performs target object selection and/or reselection;

Specifically, when the remote terminal receives the first indication information in step 83, the remote terminal may initiate RRC establishment and/or RRC reestablishment through the selected target relay terminal or target cell.

If the remote terminal discovers that there are multiple target relay terminals and/or target cells meeting the conditions at the same time, the remote terminal may also perform one of the following operations:

Preferentially select the target cell to initiate the RRC reconstruction or RRC establishment process;

Preferably, the target relay terminal initiates an RRC reestablishment or RRC establishment process to the serving cell of the target relay terminal;

Depending on the implementation of the terminal, it is determined to select the target cell, or the target relay terminal initiates an RRC reestablishment or RRC establishment process to the serving cell of the target relay terminal.

Embodiment 2: The relay terminal fails to reconfigure on the Uu interface; as shown in FIG. 9 , the method includes:

Step 91: The network device sends an RRC reconfiguration message to the relay terminal through the Uu interface;

Step 92: The relay terminal determines that the reconfiguration of the relay terminal on the Uu interface fails;

Once the relay terminal judges that the reconfiguration of the relay terminal on the Uu interface fails, different processing can be adopted according to the relevant parameters of the Uu interface reconfiguration failure, as follows:

If the reason for the reconfiguration failure includes the failure to configure the Uu interface parameters of the relay terminal, then optionally, step 93a and step 94 may be continued; in other cases, step 93b may be continued.

Among them, the relay terminal Uu interface parameter configuration may include one or a combination of the following: the configuration required by the Uu interface when the relay terminal does not work as a relay (such as measurement configuration, the bearer required for the data transmission of the relay terminal itself on the Uu interface) configuration, etc.); the configuration required for the Uu interface when the relay terminal works as a relay (such as the mapping relationship between the Uu interface RLC channel and the PC5 RLC channel, the Uu interface for carrying the bearer configuration of the remote terminal data, etc.).

Specifically, other situations may refer to relay-related configuration failures, such as failure to configure the mapping relationship between the Uu interface RLC channel and the PC5 RLC channel, or failure to configure the direct communication interface between the relay terminal and the remote terminal, etc. .

The ID of the direct communication link that failed to reconfigure.

Step 94: the remote terminal performs target object selection and/or reselection;

Optionally, step 94 is performed only after step 93a is performed.

For example: the remote terminal can perform relay reselection, and after selecting a new relay terminal, it can initiate an RRC establishment or RRC reconstruction process to the network device through the new relay terminal. If the remote terminal is triggered to perform target object selection and/or reselection, the remote terminal may initiate an RRC reestablishment or RRC establishment process through the selected target relay terminal or target cell.

Preferably, the target relay terminal initiates an RRC connection reestablishment or RRC connection establishment process to the serving cell of the target relay terminal;

Embodiment 3: The reconfiguration of the direct communication interface from the relay terminal to the remote terminal fails; as shown in FIG. 10 , the method includes:

Step 101: the relay terminal sends a direct communication interface RRC reconfiguration message to the remote terminal;

Taking the NR system as an example, the RRC reconfiguration process may use the RRCReconfigurationSidelink message.

Step 102: the relay terminal determines that the reconfiguration of the direct communication interface between the relay terminal and the remote terminal fails;

Specifically, if the remote terminal cannot interpret part of the information in the RRC reconfiguration message sent by the relay terminal, it may be determined that the reconfiguration of the direct communication interface from the relay terminal to the remote terminal fails. At this time, the remote terminal needs to send a reconfiguration failure message to the relay terminal. If the reconfiguration failure message can use the direct communication interface RRC reconfiguration failure (RRCReconfigurationFailureSidelink) message, and indicate that the cause of the failure is the direct communication interface reconfiguration failure, then the middle The relay terminal may determine that reconfiguration of the direct communication interface from the relay terminal to the remote terminal fails.

Step 103: the relay terminal executes the processing after the direct communication interface reconfiguration from the relay terminal to the remote terminal fails;

If the RRC reconfiguration of the direct communication interface between the relay terminal and the remote terminal fails, the behavior of the relay terminal can be one or a combination of the following:

Way 1: Execute step 104a.

Method 2: If the configuration of the direct communication interface from the relay terminal to the remote terminal already exists before the reconfiguration of the direct communication interface, continue to use the configuration before the reconfiguration, and execute step 104b.

Step 104a: the relay terminal sends second indication information to the network device;

Optionally, the relay terminal sends second indication information to the network device through the Uu interface, where the second indication information carries parameters related to the RRC reconfiguration failure of the direct communication interface from the relay terminal to the remote terminal,

The reason for the direct communication link configuration failure;

Direct communication link configuration failed;

The relay link identifier of the failed reconfiguration;

The ID of the direct communication link that failed to reconfigure.

It should be noted that, if the remote terminal performs the above operation after step 101, then step 104b can be omitted.

If the remote terminal performs relay reselection, after a new relay terminal is selected, an RRC establishment or RRC reestablishment process can be initiated to the network device through the new relay terminal. If the remote terminal is triggered to perform target object selection and/or reselection, the remote terminal may initiate an RRC reestablishment or RRC establishment process through the selected target relay terminal or target cell.

The end-to-end RRC reconfiguration signaling specifically refers to the end-to-end RRC reconfiguration signaling between the network device and the remote terminal, that is, the relay terminal is only responsible for forwarding and will not parse the RRC signaling.

Step 132: the remote terminal determines that the end-to-end RRC reconfiguration between the remote terminal and the network device fails;

Specifically, if the remote terminal cannot interpret part of the information in the end-to-end RRC reconfiguration message between the remote terminal and the network device, it can be judged as an end-to-end RRC reconfiguration between the remote terminal and the network device fail.

Step 133: the remote terminal executes the processing after the end-to-end RRC reconfiguration between the remote terminal and the network device fails;

The remote terminal determines that the end-to-end RRC reconfiguration between the remote terminal and the network device fails, and triggers the remote terminal to perform target object selection and/or reselection.

If the remote terminal determines that the end-to-end RRC reconfiguration between the remote terminal and the network device fails, it triggers the remote terminal to perform target object selection and/or reselection.

Step 143b: the remote terminal sends end-to-end third indication information to the network device;

For example: if the remote terminal judges that the end-to-end RRC reconfiguration between the remote terminal and the network device fails, and the reason for the reconfiguration failure only includes the failure of the direct communication interface parameter configuration between the remote terminal and the relay terminal, then The remote terminal sends third indication information to the network device.

Specifically, the remote terminal may continue to use the end-to-end configuration used before receiving the end-to-end reconfiguration signaling (for example, continue to use the configuration used before receiving the RRC reconfiguration message), and send third indication information to the network device, the The third indication information carries relevant parameters of failure of end-to-end RRC reconfiguration between the remote terminal and the network device.

Step 151: the remote terminal sends a direct communication interface RRC reconfiguration message to the relay terminal;

Step 152: the remote terminal determines that the reconfiguration of the direct communication interface between the remote terminal and the relay terminal fails;
