Description

Relay switching method, device, remote terminal, relay terminal and network side equipment

technical field

The present application belongs to the technical field of communication, and specifically relates to a relay switching method, device, remote terminal, relay terminal and network side equipment.

Background technique

The current technology stipulates the relay handover scenario of the same base station. When the remote terminal performs direct switching to the non-direct path, the remote terminal needs to provide at least one of the following information to the base station: Alternate relay user equipment (UserEquipment, UE) Identification; the serving cell of the candidate relay UE; the secondary link measurement quality information of the candidate relay UE. For the above handover, since the handover is always the same base station, the base station can judge the connection status of the candidate relay UE, and then determine which relay UE to select to determine the handover path.

However, in relay communication, due to the mobility of the remote UE, the scenario of path switching may occur, including the situation that the remote UE switches from the direct path to the non-direct path, and the direct path and the non-direct path are different base stations (cross-base station path switching). For the scenario of inter-base station path handover, the source base station and the target base station are not the same. In the case of no interaction between the two, the connection status of the candidate relay UE cannot be judged, so there is no judgment on the target path/target relay selection According to the basis, the handover delay increases and the service experience decreases.
