System, apparatus, and method for circuit switched fallback reliability in wireless communication systems

摘要

In accordance with aspects of the disclosure, a method, apparatus, and computer program product are provided for wireless communication. The method, apparatus, and computer program product may be configured to determine that a device is switching from a first cell and a first location to a second cell and a second location to implement a mobile terminated circuit switched fallback process, generate a routing area update message including a flag indicating a pending data packet for communication, and transmit the generated routing area update message.

主权项

1. A method for wireless communication in a device, comprising:
switching from a first cell associated with a first mobile switching centre that provides coverage to a first geographical area to a second cell associated with a second mobile switching centre that provides coverage to a second geographical area to implement a mobile terminated circuit switched fallback process; generating a routing area update message including a flag indicating a pending data packet for communication, wherein the flag comprises a Follow-On Proceed flag; transmitting the generated routing area update message; when the flag indicates a pending data packet;
maintaining a connection to the second cell for a period of time, andperforming a call setup procedure; when the flag does not indicate a pending data packet;
releasing connection to the second cell;receiving a paging message at the device;establishing connection to the second cell;performing a call setup procedure.
