Patent ID: 7477896

Claim:
A device in a wireless communication system, comprising: a reselection unit operative to provide an indication to perform cell reselection from a first base station to a second base station; a control unit operative to initiate a cell reselection procedure for the second base station in response to the indication from the reselection unit, wherein the first base station is a current serving cell and the cell reselection procedure selects the second base station as a new serving cell; and a monitoring unit operative to receive from a broadcast channel of the second base station sufficient system information to process a paging channel of the second base station, to determine which particular time intervals are assigned to the device for the paging channel based on the sufficient system information, to start monitoring the paging channel upon reception of the sufficient system information from the second base station and prior to completion of the cell reselection procedure, and to monitor the paging channel during the time intervals assigned to the device to detect for paging messages sent by the second base station to the device; whereby the device performs an early camping operation which reduces a time gap for receiving paging messages from the second base station during cell reselection; wherein the sufficient system information is System Information Type 3 in a Global System for Mobile Communications (GSM) system.
