Abstract:
A communication system is provided that allows a Hybrid Access Terminal (HAT) that is monitoring, or is engaged in a circuit voice call in, a circuit switched network and has a dormant packet data session anchored on a packet switched network, to send packet data to, and to receive packet data from, a packet data network connected to the packet switched network without having to switch to the packet switched network and even though a packet data session is not established in the circuit switched network.
