Method for signalling a rich call capability indication in a mobile communication system

摘要

The invention relates to a method for establishing a circuit switched call between a first electronic device and a second electronic device over a circuit switched communication system, exchanging of capabilities of the first electronic device and the second electronic device, establishing a media component between the first electronic device and the second electronic device over a packet switched communication system. In the method also radio access network information is obtained to the first electronic device. The first electronic device requests an in-band signal to the second electronic device for indicating an availability of a type of the media component. The second electronic device detects the in-band signal in the second electronic device and indicates the availability of the type of the media component on a user interface of the second electronic device.
