Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the concrete implementation of technical scheme is described in further detail:

[0027] Fig. 1 is a schematic diagram of the system structure of an embodiment of the present invention, as shown in the figure, the system includes a SIP visual terminal 101, a SIP voice terminal 102, an access device 103, a soft switch 104, a media server 105, and an ordinary voice terminal 106, wherein:

[0028] The SIP visual terminal 101, as the calling terminal for receiving and viewing the ringback image, is connected to the packet switching network through twisted pair, WLAN and other methods. The visual terminal selected in the embodiment is a terminal based on the SIP protocol with a video function.

[0029] The SIP voice terminal 102 is directly connected to the packet switching network, and it may be a terminal with only voice function, and does not need to have a visual function as a called party. In the embodiment, a SIP voice t...

Abstract

The method comprises: the calling terminal with video capability initiates a calling request; the soft switching equipment informs the called end to make ringing; after the soft switching equipment receives the ring-back tone message from the called terminal, according to service information of imaging the ring-back tone registered by the called terminal in the soft exchange equipment, the soft switch equipment informs the media server to allocate transmission resources; after the media server allocates resources successfully, the soft switch equipment modifies the media attributes of the called terminal as the resource information of media server, and sends ring back tone message to the calling terminal; after the calling terminal receives the ring back tone message carrying the media information, it opens media channel to receive the image from the media server.

Description

technical field [0001] The present invention relates to a system and method for providing ringback service in the next generation network, in particular to a system and method for providing ringback image service in the next generation network. Background technique [0002] The next generation network (Next Generation Network, NGN) adopts the soft switch as the control core, and uses the packet switching network as the transmission network. It is a comprehensive and fully open network platform system that can simultaneously provide multiple services such as voice, image, and data. The business-driven network, how to conveniently and flexibly provide more value-added services and new services in the next-generation network has become its current mainstream development direction. [0003] With the construction of mobile broadband networks such as 3G and WLAN, and the popularization of fixed broadband access networks such as ADSL and LAN, the promotion of visual terminals becom...
