Abstract

Provided are a method and method for improving video telephony service quality by preventing call setup failures or service quality degradation due to user equipment (UE) switching during video call setup to a network that cannot achieve the data rate required for video telephony. device. The communication method of a terminal in a mobile communication system according to the present disclosure includes: sending a video phone call setup request message, receiving a handover command for circuit switched fallback (CSFB), and if the handover command includes ) cell type and if a 3rd generation (3G) cell to which the terminal can access exists, a video phone call is set up by handing over the connection to the 3G cell.

Description

technical field [0001] The present disclosure relates to selecting an access network in a mobile communication network to establish a connection for video telephony. In particular, the present disclosure relates to improving video telephony service quality by preventing call setup failures or service quality degradation due to user equipment (UE) switching during video call setup to a network that cannot achieve the data rate required for video telephony Methods and Apparatus. Background technique [0002] Mobile communication systems are developed to provide users with voice communication services on the move. With the rapid advancement of technology, mobile communication systems have evolved to support high-speed data communication services in addition to early voice-oriented services. However, limited resources in current mobile communication systems and users' demands for higher-speed services prompt evolution to higher-level mobile communication systems. [0003] As ...
