Abstract
A packet-switched voice call directed to a mobile subscriber unit in a cellular communication network is processed by determining whether the mobile subscriber unit is in a circuit-switched mode of operation and, if so, either forwarding the information in the packet-switched voice call to a destination other than the mobile subscriber unit or notifying the mobile subscriber unit that the packet-switched voice call is waiting.
