Digital-image mapping generating method, digital-image sending system and method

Abstract

The present invention discloses a figure-picture downward transferring method comprising: a step of S402, a communication terminal sending a petition signal toward a first communication device; a step of S404, the first communication device responding to the petition signal and sending a notice signal to a second communication device; a step of S406, the second communication device responding to the notice signal and sending an identification code to the first communication device; a step of S408, the first communication device responding to the identification code and citing the figure-picture which is corresponding to the identification code; and a step of S410, the first communication device downwardly transferring the figure-picture to the communication terminal. The present inventionalso discloses a generation method of figure-picture mapping used for establishing a corresponding relationship between the figure-picture and the identification code, which includes: establishing the identification code corresponding to the figure-picture at the second communication device; the second communication device sending a first information containing the figure-picture and its corresponding identification code to the first communication device; and the first communication device receiving and recording the first information come from the second communication device.

Description

technical field [0001] The present invention relates to the field of communication technologies, and more specifically, to a digitmap mapping generation method and a digitmap distribution system and method. Background technique [0002] In the NGN (Next Generation Network, next-generation network) network, the biggest feature is that the call control and bearer are separated. The call control function is realized by the SS (Soft Switch, Soft Switch), and the bearer of the media stream is mainly in the MG (MediaGateway, media gateway). The interaction between the SS and the MG is mainly realized through a media gateway control protocol (such as H.248). The user is connected to the MG, and the MG detects the user's dialed number according to the current Digit Map (digit map) definition rule and reports it to the SS, and then the SS determines the follow-up processing of the call according to the dialed called number. [0003] NGN network is an open architecture, it can commu...

Problems solved by technology

This method has the following disadvantages: (1) Even if the number is sufficient, there will be a situation where the SS sends redundant Digit Maps, resulting in redundant message exchange and redundant number collection processing by the MG; (2) For variable In the case of long number dialing, when the number dialed by the user matches the Digit Map and reports it for the first time, the SS downloads the Digit Map to the MG digit by digit to collect the number, which will cause too many message interactions between the SS and MG. Analysis of the internal number of the SS Or the number of user positioning will also increase unnecessarily, and at the same time, it will also cause the SS to send numbers one by one between offices, which will definitely affect performance, call connection speed and success rate

This method has the following disadvantages: due to the complex network and rich services, the complete Digit Map is often very large (after analyzing the possible dial plan of a certain operator, the constructed Digit Map reaches 8K bytes); at the same time, a The number of users under MG is also large

Therefore, although this method overcomes the problem of excessive number of message interactions in the first method, it greatly increases the capacity of each message, and a huge Digit Map needs to be issued for each user off-hook event. still consumes a lot of network resources
