Abstract

A wireless terminal (30) communicates across a wireless interface with a Long Term Evolution (LTE) radio access technology network (22-1) and a circuit switched network (22-2). The wireless terminal (30) establishes a circuit switched call with the circuit switched network (22-2); maintains a packet switched session with the Long Term Evolution (LTE) radio access technology network (22-1) during establishment of the circuit switched call; and, multiplexes transmissions of the packet switched session with transmissions of the circuit switched call.
