Abstract
A pre-synchronization method in which the source cell chooses a signature for the user equipment (mobile) to use in the target cell for RACH access, and instructs the user equipment to perform RACH access and return to the current cell before a handover command (break command) is issued. This causes parallel execution of the UL synchronization process with the context transfer process among the two base stations.
