APPARATUS AND METHOD FOR MAINTAINING A CIRCUIT-SWITCHED VOICE CALL IN A MULTI-RAB WIRELESS COMMUNICATION SYSTEM IN AN AREA OF WEAK COVERAGE |
摘要 |
An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call. |
