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).
Claims20
A method, comprising:
- detecting, at a mobile management entity (MME), one or more pending circuit switched fallback (CSFB) requests;
- generating, in response to detecting the one or more pending CSFB requests, a message that indicates the one or more pending CSFB requests;
- and
- communicating the message to one of a mobile switching center (MSC) and a virtual location register (VLR).
1 more element
A method, comprising:
- receiving, at a wireless transmit/receive unit (WTRU), an instruction for managing a circuit switched fallback (CSFB) request;
- and
- in response to receipt of the instruction, implementing the instruction in a radio access technology (RAT) environment.
A method comprising:
- receiving, at a mobile management entity (MME), a paging request for a circuit switched fallback (CSFB) request;
- and
- in response to receipt of the paging request, communicating to a wireless transmit/receive unit (WTRU) an instruction for managing the circuit switched fallback (CSFB) request.
