Abstract
A method for wireless communication at a target network entity and related apparatus are provided. In the method, the target network entity receives a handover request to the target network entity for one or more user equipment (UEs). The handover request indicates a link failure with a source network entity as a cause for the handover request. The target network entity further receives a re-establishment request from one UE of the one or more UEs and communicate with the one UE based on a UE context obtained prior to the re-establishment request.
Claims30
An apparatus of wireless communication at a target network entity, comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories and, based at least in part on stored information that is stored in the one or more memories, the one or more processors, individually or in any combination, are configured to cause the target network entity to:
- receive a handover request to the target network entity for one or more user equipment (UEs), the handover request indicating a link failure with a source network entity as a cause for the handover request;
- receive, from one UE of the one or more UEs, a re-establishment request;
- and
- communicate with the one UE based on a UE context obtained prior to the re-establishment request.
An apparatus of wireless communication at a source network entity, comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories and, based at least in part on stored information that is stored in the one or more memories, the one or more processors, individually or in any combination, are configured to cause the source network entity to:
- detect a link failure for one or more user equipment (UEs);
- and
- provide a handover request for a target network entity for each UE of the one or more UEs, the handover request indicating the link failure as a cause for the handover request, wherein the handover request causes the target network entity to prepare a UE context for the one or more UEs prior to receiving a re-establishment request from the one or more UEs.
