Abstract:
The present disclosure presents a method and apparatus for expedited mobile device handover that include performing one or more handover tasks in parallel that have previously been performed exclusively in serial. For example, the disclosure presents a method for wireless device handover, which may include acquiring a target cell, ascertaining a system frame number (SFN) of the target cell, calculating a connection frame number (CFN) for a dedicated channel (DCH) transmission, and reconfiguring a dedicated physical channel (DPCH) based on the calculated CFN. In addition, such an example method may include, while performing at least one of the ascertaining of the SFN, the calculating of the CFN, and the reconfiguring of the DPCH, contemporaneously performing at least one of establishing a downlink dedicated physical channel (DL-DPCH), establishing a synchronization with the target cell, and establishing an uplink dedicated physical channel (UL-DPCH) subsequent to the downlink synchronization.
