Abstract (en)

[origin: WO0147298A2] There is disclosed a system for re-selection to a neighbor cell while a mobile station is engaged in a packet data session in a cellular packet data network system. The system includes a mobile station control system adapted to transmit a request to change the channel from a serving base station of the packet data session to a new base station, and if the request is accepted, then the mobile station acquires service with the new base station, otherwise continuing communication with the serving base station. A network control system is adapted for the serving base station to communicate with the new base station to selectively accept or reject the request to change channel, and to transmit a response to the mobile station indicating that the request was accepted or rejected, and if the request is accepted to also transmit identification information for a new channel associated with the new base station.
