ABSTRACT:
A mobile device, system, and method are disclosed for use in a wireless communication system during the mobile device's transition from a dual mode, in which a packet switched connection and circuit switched connection are used together, to a single mode in which packets are transferred. When the circuit switched connection is released, packet resources are allocated by converting timeslots used for circuit switched connection traffic into timeslots used for packet data traffic. Also included is a new alert signal within an existing message to the mobile device during the circuit switched connection release phase, before completion of the circuit switched connection release phase, in order to inform the mobile device that the converting step will occur after release of the circuit switched connection.
