Title:
METHOD AND APPARATUS FOR CREATING VOICE BEARER
Document Type and Number:
WIPO Patent Application WO/2018/102970
Kind Code:
A1
Abstract:
The present application discloses a method and apparatus for creating a voice bearer. The method comprises: a mobility management entity (MME) acquiring first indication information from a tracking area to which a target base station belongs or from a source base station, the first indication information being used to indicate whether the target base station supports a packet-switched (PS) voice bearer and/or whether strength of a PS signal of the target base station is greater than or equal to a strength threshold; and the MME sending second indication information to a gateway device when the target base station does not support the PS voice bearer or the strength of the PS signal of the target base station is less than the strength threshold, the second indication information being used to indicate creation of the PS voice bearer has failed. The method and apparatus for creating a voice bearer provided in embodiments of the present application reduce delays in creation of voice bearers by calling terminal devices, thus reducing signaling overheads of network devices.
