Problems solved by technology

[0005] Using the above method to build the No. 7 signaling network requires building more TDM relays, and the investment in TDM relay resources is high, which makes the construction cost of the No. 7 signaling network high. Moreover, the bandwidth of the signaling link is limited, and the networking Poor flexibility

Embodiment Construction

[0029] The core of the IP-based signaling system and signaling transmission method of the present invention is: the IP signaling transfer point supports the SIGTRAN protocol family, the signaling point is connected to the IP signaling transfer point, and the No. 7 signal is transmitted through the SIGTRAN protocol family The connection between the IP signaling transfer points, and the No. 7 signaling is transmitted between the IP signaling transfer points through the SIGTRAN protocol suite.

[0030] The IP-based signaling system and signaling transmission method provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0031] The present invention builds an IP-based SS7 network through IPSTP (IP Signaling Transfer Point). The simple framework of the SS7 network in the 3G system built through IPSTP is shown in Figure 2.

[0032] In Figure 2, the No. 7 signaling is transmitted between SP1 and IPSTP1 through the SIGTRAN...

Abstract

This invention provides a signal system based on IP and a transmission method, which utilizes the IP signaling switching point supporting SIGTRAN protocol group to set up the signal system, and saves plenty of relay circuits and reduces relay interface boards so as to reduce cost of network devices. The IP connection among network devices in the signal network does not stickle to the TDM relay resource of traditional signal network, so the connection becomes more flexible.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an IP-based signaling system and signaling transmission method. Background technique [0002] In the 3G mobile network, the MSC Server (Mobile Service Controller) can continue to use the ISUP (Integrated Services Digital Network User Part) protocol for communication, or use the BICC (Bearer-Independent Call Control) protocol defined by the R4 specification to communicate. [0003] The BICC protocol can be applied to the STP (Signaling Transfer Point) signaling network, and can also be applied to the IP network. However, in order to realize the unified management of GT (global) code translation and signaling, MAP (Mobile Application Part), CAP (Intelligent Application Part)-related signaling must be carried on the STP signaling network, so a No. 7 signaling network needs to be constructed in the 3G mobile network. [0004] At present, in the 3G network, the traditi...
