METHOD AND APPARATUS FOR SETTING UP CALL IN MOBILE COMMUNICATION SYSTEM |
摘要 |
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. |
