Abstract
(57) (Summary) A reselection method for switching a packet data session from a first packet data channel in a first cell of a communication network to a second packet data channel in another cell. Reduce the time required. While the mobile station is engaged in a packet data session on the first packet data channel, it continuously monitors the channel quality of the control channel in neighboring cells. When a predetermined criterion is satisfied, one or more adjacent control channels are recognized as potential reselection candidates. During the data packet session, the mobile station reads at least part of the broadcast information on the control channel recognized as a potential reselection candidate. The broadcast information is read from the adjacent control channel prior to making the reselection decision. When the predetermined reselection criteria are satisfied, the mobile station switches to a new packet data channel in the selected cell. Since the mobile station has already read the broadcast information in the selected cell, it can immediately acquire the service of the new packet data channel.
