Handover technique for cellular network

摘要

There is disclosed a method for achieving fast handover in a cellular communication network which is particularly advantageous in a packet switched wireless network. The method is particularly advantageous when applied in an environment in which a mobile has only one transceiver. A mobile system determines whether a neighbouring cell offers a stronger signal than the current cell, and sends a signal to the current cell indicating the identity of the cell to which it has determined a handover is desirable. The network is re-configured to establish a communication link with the mobile system via the new cell. Once the network is re-configured, the mobile station is notified via the current cell, and the mobile system starts communication via the new cell. <IMAGE>
