Abstract

The present invention provides a method and device for managing calls during a handover process in a communication system, wherein the method for managing calls during a handover process in the communication system includes: receiving a request to disconnect a voice call from an end user; determining whether to execute single wireless mode a voice call continuity or reverse single radio mode voice call continuity handover process; and when the disconnection of the voice call continuity is received during the single radio mode voice call continuity or reverse single radio mode voice call continuity handover process; When a call is requested, perform a behavior for the voice call. The method for managing calls during the handover process in the communication system provided by the present invention can successfully avoid problems that may occur when user devices handle call requests during the handover process between different networks, and ensure call quality.

Description

[0001] Cross References to Related Applications [0002] The scope of the claims of this application claims priority to US Provisional Application No. 61 / 988,392, filed May 5, 2014. The entire contents of the aforementioned US Provisional Application are hereby incorporated by reference. technical field [0003] The present invention relates generally to wireless communication systems, and more particularly to methods and apparatus for managing calls in a communication system during a single radio mode voice call continuity handover procedure or a reverse single radio mode voice call continuity handover procedure. Background technique [0004] Wireless communication systems are widely configured to provide various types of communication such as voice, packet data, and so on. These systems may be based on Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), or other various access techniques. For example, th...
