Abstract

Provided are an apparatus and method for switching a call by a User Equipment (UE) supporting a Voice Call Continuity (VCC) scheme in a mobile communication system. The method includes: detecting that a UE supporting the VCC scheme is transmitting / receiving data in the first access network through an old bearer established with another party UE, and that there is a need for switching a voice call from the first access network to the first access network. the needs of a second access network different from the incoming network; perform a new bearer establishment operation with the second access network; and send / receive voice data with the other party UE in the first access network through the old bearer and through the new bearer Send / receive voice data with the other party UE in the second access network until a point in time.

Description

Technical field [0001] The present disclosure relates to a device and method for switching calls in a mobile communication system. More specifically, the present disclosure relates to an apparatus and method for switching voice calls in a mobile communication system supporting a dual wireless voice call continuity (DRVCC) scheme. Background technique [0002] If new mobile communication schemes such as Long Term Evolution (LTE) scheme, Long Term Evolution Advanced (LTE-A) scheme, etc. are introduced in the mobile communication scheme, the mobile communication scheme provides limited services in the time interval before establishing a complete network Coverage. If the network in which the new mobile communication scheme is introduced supports Voice over IP (VoIP) service, due to the limitation of the service coverage, when the user device (UE) moves out of the service coverage, the voice call received by the UE is terminated. [0003] In order to solve this problem, the 3rd Genera...
