Abstract:
1. A method for facilitating a forward handover in a communications system, comprising: receiving, at a target base station, a first message from a user terminal indicative of a Random Access Channel (RACH) procedure to initiate access to the target base station; sending, from the target base station, a second message to the user terminal to initiate access to the target base station; receiving, at the target base station, a third message comprising a connection reestablishment request including first identity information from the user terminal for retrieval of user context information stored at a source base station; initiating, at the target base station, retrieval of the user context information from the source base station; sending, from the target base station, in response to failure to retrieve the user context information, a fourth message to the user terminal informing the user terminal to continue the forward handover without performing another RACH procedure; and receiving, at the target base station, a connection request message from the user terminal.
