SIP voice terminal or normal speech terminal have been registered the business of echo-bell imaging in advance in soft switch, and activate, and in addition, SIP voice terminal or normal speech terminal have also selected corresponding image as the ring-back image, are kept in the media server.
Fig. 2 is the schematic flow sheet of the embodiment of the invention, wherein, selects for use the SIP video terminal as calling terminal in the present embodiment, and the SIP voice terminal is as terminal called.The flow process of treatment step is as follows:
1, caller sends the INVITE call request to soft switch, carries we's video capability in SDP;
2, soft switch is to called forwarding INVITE call request;
3, calledly send 180 ring-back message to soft switch;
4, soft switch inquires the called echo-bell imaging service of having opened, and sends Add message informing media server Resources allocation;
5, media server returns Reply message to soft switch, and resource allocation result is described;
6, soft switch sends Modify to media server, upgrades the distant end media attribute;
7, media server returns Reply message to soft switch, and the resource updates result is described;
8, soft switch sends 180 ring-back message to caller, wherein, carries the video capability of media server;
9, caller receives the also ring-back image of display media server;
10, called off-hook sends 200 responses to soft switch;
11, soft switch sends Modify message, and the notice media server stops playback;
12, media server returns Reply message to soft switch, and the resource updates result is described;
13, soft switch sends Subtract message, and the notice media server discharges resource;
14, media server returns Replay message to soft switch, illustrates that resource discharges the result;
15, soft switch is transmitted 200 responses to caller, wherein, carries called media capability in SDP;
16, caller is replied ACK message to soft switch;
17, soft switch to called commentaries on classics ACK message;
18, conversation is set up.
In the above-described embodiments, when terminal called was selected the normal speech terminal, it need pass through the access device access network, and the normal speech terminal is then carried out Signalling exchange by access device and Softswitch.
The invention provides a kind of system and method for the new business that on next generation network, realizes, strengthened the manufacturing capacity of next generation network equipment manufacturer, enriched the type of service of operator, for the user provides a platform of showing the oneself, simultaneously, also better transmit information platform, opened up a kind of new application direction for the user has built one.
