Title:
UE SWITCHING PROCESS WITH SUSPENSION AND SUBSEQUENT RESUMPTION FOLLOWING A HANDOVER FAILURE
Document Type and Number:
WIPO Patent Application WO/2023/119976
Kind Code:
A1
Abstract:
A method for a user equipment (UE) is provided. The method includes the UE maintaining a Radio Resource Control (RRC) connection with a first base station (BS) of a first network while receiving transmissions from a second BS of a second network during at least one time period specified in a switch gap configuration. The UE receives an RRC reconfiguration message from the first BS that includes a first command and a second command. The first command instructs the UE to begin a handover procedure from the first BS to a third BS. The second command controls usage of the switch gap configuration by the UE following a failure of the handover procedure. The UE initiates the handover procedure according to the first command. The UE may suspend reception of transmissions from the second BS following reestablishment of the RRC connection after the handover failure based on the second command.
