System and method for realizing fixed network one-code-through color ring service by using soft exchanging technology

Abstract

The invention relates to a system for realizing first color bell service with soft exchange technique, and relative method, wherein said system at least comprises: application server AS, media server MRS, and web server which are connected by local network to form service platform as application layer; it uses soft exchanger SS as control layer, and uses the IP grouped network with confirmed service quality QoS as carrier layer, and uses the soft exchange network formed by signal gateway SG of local network PSTN and relay gateway TG as access layer, and relative PSTN; the soft exchange network is one increment service platform independent from local network PSTN, and spanning local network, to connect the PSTN via SG and TG, to realize the first color bell service via special number section. The invention has simple structure and lower cost.

Description

technical field [0001] The invention relates to a system and a method for realizing the one-number ring ring service in a fixed network by using the softswitch technology, and belongs to the field of softswitch network technology. Background technique [0002] Universal Personal Telecommunications (UPT, Universal Personal Telecommunication), also known as universal personal communication, is a new type of mobile communication service. Users only need to use a unique personal communication number to access fixed network, PHS network, GSM network or Any network in the CDMA network can initiate and receive calls across multiple networks, and the calls are not affected by the geographical location. [0003] At present, the implementation of the One Number ring back tone service on the fixed network is constructed by using the traditional intelligent network service switching point SSP (Service Switch Point)-service control point SCP (Service Control Point). The traditional intel...

Problems solved by technology

To implement the CRBT function, the SSP must communicate with the external CRBT gateway. However, the CRBT gateway is not necessarily installed in the local network, so the networking is complicated, and the circuit from the SSP to the CRBT gateway needs to be occupied, which is a waste of resources.

[0006] (3) When binding a receiving number across a local network, it needs to go through the local SSP to the long-distance office, and then occupy a long-distance trunk, wasting a certain amount of long-distance trunk resources
