Among them, the UE that is not connected to the network device is called the remote UE (remote UE), and the UE that provides the relay function is called the relay UE (relay UE). The remote UE and the relay UE are connected through direct sidelink unicast. communication. However, when the relay UE enters the idle state due to the timeout of the data inactivity timer, or when the Radio Resource Control (RRC) is reestablished due to a reconfiguration failure, the RRC connection between the relay UE and the network device will be interrupted. This interruption will not notify the remote UE, causing the remote UE to fail to transmit.

As a possible implementation manner, the data inactivation timer of the relay UE times out, and it is determined that the RRC connection between the relay UE and the network device is interrupted.

As an example, the data inactivity timer configured by the network device for the UE times out, the relay UE automatically releases the RRC connection, determines that the RRC connection between the relay UE and the network device is interrupted, and the relay UE sends a notification message to the remote UE. , this notification message is used to indicate that the RRC connection between the relay UE and the network device is interrupted.

As another possible implementation manner, the relay UE enters the idle state and determines that the RRC connection between the relay UE and the network device is interrupted.

As an example, the network device sends an RRC connection release message. After receiving the RRC connection release message, the relay UE can release the RRC connection with the network device and enter the idle state. When the relay UE enters the idle state, it determines whether the relay UE is connected to the network. The RRC connection between devices is interrupted, and the relay UE sends a notification message to the remote UE.

As another possible implementation manner, the relay UE fails to be reconfigured, and the RRC connection between the relay UE and the network device is interrupted.

As an example, the relay UE fails to perform relay UE reconfiguration, determines that the RRC connection between the relay UE and the network device is interrupted, and the relay UE sends a notification message to the remote UE.

As another possible implementation manner, the relay UE starts RRC reestablishment and determines that the RRC connection between the relay UE and the network device is interrupted.
