Definitions
- Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method, apparatus, and system for terminating a circuit switched domain to return to a conventional network call. Background technique
- GPRS/UMTS is a mobile communication network defined by the 3GPP organization and has been widely deployed. It includes two parts: Radio Access Network (RAN) and Core Network (CN).
- the CN is logically divided into a Circuit Switched Domain (CS) and a Packet Switched Domain (PS).
- CS Circuit Switched Domain
- PS Packet Switched Domain
- the CS domain mainly handles voice services
- the PS domain mainly handles packet services.
- the signaling plane control entity of the CS domain is the Mobile Switch Center/Visitor Location Register (MSC/VLR), and the signaling plane control entity of the PS domain is the Serving GPRS Support Node (SGSN). ).
- MSC/VLR Mobile Switch Center/Visitor Location Register
- SGSN Serving GPRS Support Node
- GPRS/UMTS network is simply referred to as a 2G/3G network.
- LTE Long Term Evolution
- EPS evolved packet system
- the MME cannot sense that the calling party has already released the call, and receives the user equipment (User Equipment, UE). After the service request is extended, the MME still triggers the subsequent call procedure of the CSFB, and sends a paging response message to the MSC through the circuit domain. Since the call resource in the MSC has been translated, the MSC considers that the received paging response message is an abnormal message and discards the message.
- User Equipment User Equipment

- VLR The MSC and the VLR in all embodiments of the present invention may be combined and collectively referred to as a VLR.
- the VLR can determine whether it is necessary to suspend the call based on the received message initiated by the caller. For example, if the calling party initiates a call release message, or a call abort message, or a call cancellation message, the VLR judges that the call needs to be aborted.
- the calling party Before the called party is connected, the calling party initiates a call release message.
- the specific reason may be that the calling party actively hangs up, the calling VLR is overloaded, and the calling VLR actively terminates the call due to the operation management OM operation aborting the call, or the calling user operating error. .
- the VLR may send a specific type of SGs message to the MME, that is, by using a message type, for example, the message type is "SGs Service Abort Request" to indicate that the MME call is released; or the message may be carried in the message to notify the MME that the call has been translated.
- a message type for example, the message type is "SGs Service Abort Request" to indicate that the MME call is released; or the message may be carried in the message to notify the MME that the call has been translated.
