Abstract: A method for switching a call by a User Equipment (UE) supporting a Voice Call Continuity (VCC) scheme in a mobile communication system is provided. The method includes detecting that there is a need for switching a voice call from a first access network to a second access network that is different from the first access network while the UE supporting the VCC scheme transmits/receives data in the first access network through an old bearer which is set up with the other party UE, performing a new bearer set up operation with the second access network, and transmitting/receiving voice data with the other party UE through the old bearer in the first access network and transmitting/receiving voice data with the other party UE through the new bearer in the second access network until a point in time.

Abstract: An apparatus and a method for reducing power consumption of an Application Processor (AP) in an electronic device are provided. The electronic device includes a first processor for supporting a first Internet Protocol (IP) Multimedia Subsystem (IMS) protocol stack, and a second processor for supporting a second IMS protocol stack. The first processor includes an AP for processing a multimedia service, and the second processor includes at least one of a Communication Processor (CP), a Modem Processor (MP), and a Baseband Processor (BP) for processing a communication service.

Abstract: The time required to set up a voice call in an exemplary embodiment, in which Circuit Switched Fallback (CSFB) is used, is reduced to provide a voice call service to a User Equipment (UE) in a Long Term Evolution (LTE) system. If a voice call occurs in a UE while the UE accesses the LTE system, the UE using CSFB switches to a 2G/3G legacy system, recycles system information for a 2G/3G cell that the UE has accessed before, and immediately proceeds with voice call setup without receiving system information unnecessary for a CSFB process.
