Abstract

In a method of operating a wireless terminal, the wireless terminal (30) sends a request to participate in a circuit switched call with a circuit switched network. Prior to establishment of the circuit switched call the wireless terminal (30) releases or performs an inter-radio access technology handover of an existing packet switched session with an original packet switched network. The wireless terminal (30) then reconnects to the packet switched session to obtain a reconnected packet switched session. Thereafter the wireless terminal (30) interleaves packet switched transmissions of the reconnected packet switched session with voice transmissions of the circuit switched call.
