Mobile Terminating Network Failure Forwarding for LTE Circuit-Switched Fallback

摘要

Techniques pertaining to mobile terminating network failure forwarding for LTE circuit-switched fallback (CSFB) are described. In one aspect, a method includes a first telecommunications device of a pool of telecommunications devices receiving a reply message from a mobile user device forwarded to the first telecommunications device by a radio access device. The reply message is provided by the mobile user device in response to the mobile user device receiving a request message from a second telecommunications device of the pool of telecommunications devices. The method also includes the first telecommunications device establishing a voice call for the mobile user device based at least in part on information in the reply message.
