Description

A kind of system and method that echo-bell imaging service is provided in next generation network

Technical field

The present invention relates to a kind of system and method that back ring service is provided in next generation network, particularly a kind of system and method that echo-bell imaging service is provided in next generation network.

Background technology

Next generation network (Next Generation Network, NGN) adopt soft switch to be the control core, by the packet switching network as transmission network, it is the network platform system that can provide the comprehensive standard-sized sheet of multiple business such as voice, image, data to put simultaneously, be the network of business-driven, how convenient, flexible provide more value-added service and new business becomes its current main-stream developing direction in next generation network.

Along with the structure of mobile broadband networks such as 3G, WLAN, and the popularizing of fixed broadband access networks such as DSL, LAN, the popularization of video terminal becomes possibility.People have no longer satisfied single speech business, more wish to realize aspectant interchange; On the other hand, people are also more and more to the demand of personalized customization business, wish to show the oneself by more mode.At present, in the business of next generation network, can provide the customization of ring-back tone, still, also not provide the business of echo-bell imaging.

It is the ring-back tone custom service of calling out other calls customer setting individual image informations of own telephone number by called party client that echo-bell imaging service is one, promptly, in the telephone call, before called off-hook is replied, calls customer not only can be heard ring-back tone, can also see the personalized image information (for example, individual photo, caricature, video clips etc.) that called party client customizes, reduce the uninteresting property in the calls customer wait process.

The system and method for echo-bell imaging service still is not provided in next generation network at present.

Summary of the invention

Technical problem solved by the invention has been to provide a kind of system and method that echo-bell imaging service is provided in next generation network, provide echo-bell imaging service to reach in next generation network.

For solving the problems of the technologies described above, the invention provides a kind of system that echo-bell imaging service is provided in next generation network, native system comprises:

Terminal called;

Calling terminal has video capability, is used for receiving and showing the ring-back image;

Media server is used to preserve the ring-back image of customization, and sends the image information of called subscriber's customization during ring-back to calling terminal;

Softswitch, be used for call request according to calling terminal, the notice dialed terminal bell, and after receiving terminal called ring-back message, the echo-bell imaging service information of registering in advance according to the called subscriber, notice media server allocation of transmission resources, and the medium property of terminal called is revised as the resource information of media server, send ring-back message to calling terminal;

Wherein, described calling terminal is opened media channel after receiving the ring-back message that carries media information, receives the also image of display media server transmission.

When described terminal called is the normal speech terminal, further comprise access device, be used for the terminal called access network;

Wherein, Softswitch is by access device notice dialed terminal bell, and receives terminal called ring-back message by access device.

The present invention further provides a kind of method that echo-bell imaging service is provided in next generation network, this method comprises the steps:

(1) has the calling terminal of video capability to the Softswitch request of making a call;

(2) Softswitch notice dialed terminal bell;

(3) after Softswitch is received the ring-back message of described terminal called, according to the echo-bell imaging service information that this terminal called is registered in Softswitch, notice media server allocation of transmission resources;

(4) after media server resources was prepared successfully, Softswitch was revised as the resource information of media server with the medium property of terminal called, and sent ring-back message to calling terminal;

(5) after calling terminal is received the ring-back message that carries media information, open media channel, the image that the receiving media server sends.

When described terminal called was the normal speech terminal, in the described step (2), access device was to dialed terminal bell under the Softswitch notice terminal called;

In the described step (3), after Softswitch is received the ring-back message of described access device, according to the echo-bell imaging service information that this terminal called is registered in Softswitch, notice media server allocation of transmission resources.

The invention enables the calling subscriber in waiting for the process that the other side answers, can not only hear voice, can also see image, further enriched the business of next generation network.When the present invention realizes, realize echo-bell imaging on next generation network, do not need called access device to support image function, also do not need terminal called equipment to support image function, therefore, dispose easily by soft switch control media server.

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.
