Managing race conditions between circuit-switched fallback requests

Abstract

Circuit switched fallback (CSFB) requests may be managed. A mobile management entity (MME) can detect one or more pending CSFB requests. In response to detecting the pending CSFB request(s), the MME can generate a message that indicates the one or more pending CSFB requests, and can communicate the message to one of a mobile switching center (MSC) and a virtual location register (VLR).
