Patent ID: 8614988

Claim:
A communication method, comprising: establishing a circuit switched call between a first electronic device and a second electronic device over a circuit switched communication system, the first electronic device comprising a user equipment; receiving a handover indication in the first electronic device; receiving radio access network information in association with the handover indication in the first electronic device; determining in the first electronic device using the radio access network information whether at least one of a radio access network and an Internet Protocol connectivity access network associated with the radio access network supports simultaneous circuit switched call and a packet switched session carrying at least one media component; requesting an in-band signal transmission to the second electronic device for indicating availability of packet switched data transfer during the circuit switched call, the request for the in-band signal transmission being sent when the first electronic device performs a handover to a new radio access network, the handover resulting in a change in the availability of the simultaneous circuit switched call and the packet switched session carrying at least one media component; and establishing a media component between the first electronic device and the second electronic device over a packet switched communication system.
