- the MS may be selected in the same geographical area as the softswitch device, or may be selected to other MSs to execute the service application, or may not be selected. MS, which causes the business application to be invalid.
- Step 701 The UE (User Equipment) sends an application request (INVITE) message to the NGN network, and the INVITE message carries the SDP (Session Description Protocol) of the UE.
- INVITE application request
- SDP Session Description Protocol

- selecting an MS for executing business application requests can have multiple implementations. For example, the MSs in the same area as the current SS can be searched according to the mapping relationship stored in the AS. If there are multiple MSs in the same area, a poll or other policy can be used to select a service application request. If there is no MS in the same area as the current SS, you can select one MS to perform a service application request for all MSs that the AS can command, or other policies.
- Step 704 The AS sends an INVITE message to the selected one for performing a service application request.
- Step 705 The selected MS is used to perform the service application request, and the 200 OK (ie, acknowledge) message is sent to the AS.
- the 200 OK message carries the selected SDP of the MS for executing the service application request.
- Step 706 The AS forwards the 200 OK message carrying the selected SDP of the MS for performing the service application request to the SS.
- Step 707 The SS sends a 200 OK message response of the SDP that carries the selected MS for performing the service application request to the UE.
- Step 708 The UE makes a service application response to the SS.
- Step 709 The SS sends an acknowledgement (ACK) message to the AS that performs the service application request.
- ACK acknowledgement
- Step 711 The AS initiates an INFO (information) message to the MS, and carries a playback command.
- Step 713 Perform an audio application service by the MS that performs the service application request.
- Step 801 The UE sends an application request by using an INVITE message to the NGN network, and the INVITE message carries the SDP of the UE.
- Step 802 The SS uses an INVITE message to trigger a service application on the AS.
- Step 804 If there is no MS capable of executing the service application request, the AS notifies the SS service application that the request is invalid. There is no MS that can execute the service application request, including the MS that does not exist in the same area as the current SS, and does not exist. When the MS is in the same geographical area as the current SS, the MS that is capable of commanding the AS or other MSs selected by the AS;
- Step 805 The notification that the service application request is invalid is transferred from the SS to the UE;
- step 804 and step 805 the AS notifies the SS service application that the invalid information can be specified by the service application, such as 480 message. After the UE receives the information that the service application request is invalid, the entire call process ends.
- the service application request processing method provided by the embodiment of the present invention only needs to improve the application server AS, and does not need to simultaneously improve other devices in the NGN network environment, such as softswitch devices, media servers, and the like. It can save resources and improve equipment utilization when implemented.
- the spirit and scope of the invention Thus, it is intended that the present invention cover the modifications and modifications
