Embodiment Construction

[0038] As shown in Figure 1, the system of this embodiment includes a signaling gateway (SG) 1 located in IP network A, a softswitch (SS) 2 located in IP network B, and a crossover network across different networks set on the network boundary IP Signaling Gateway (IPSG)3. IP network A and IP network B are IPv4 private network and IPv6 public network respectively. The SS in the figure may also be a media gateway controller (MGC), and the SS and SG may also be other IP signaling devices such as an IP signaling endpoint (IPSEP), and the number of devices is not limited.

[0039] The IPSG is directly connected to the two networks and is equipped with effective IP addresses of the two networks. The SG and SS / MGC connected to the IPSG are respectively configured with the IP addresses of the IPSG on the same network. The SG and SS need to cross the boundaries of different networks to transmit the telecommunication signaling messages encapsulated in the user adaptation protocol, and ...

Abstract

A method that makes communicational signaling message to transit the boarder of private network includes: the IP signaling Gateways (IPSG) of multiple IP network equipments in the different IP netorks that are set among cross-network systems, the different IP addresses are allocated to IPSG that is connected with IP signaling equipmen in same network side through IPSGP at the two networks sides, in order to package the signaling message into the interlayer interface for making parameter mapping, and the signaling message is newly packaged into IP protocol packet. The process relationship between the relevant process and the signaling message is set at both IP signaling equipment and IPSG to determine the distribution strategy of signaling message. The invention adopts IPSG to transmit relay signaling at boarder of private network, the signaling equipment is only connected with IPSGP at same network side. Thus both the public network and private network can initiatively set link and have the definite opposite side address, meanwhile can also support multiple address chaining.

Description

technical field [0001] The invention relates to a method for transmitting signaling messages in the communication field, in particular to a method for transmitting traditional telecommunication network signaling on the IP Internet. Background technique [0002] In order to smoothly transition from the traditional telephone network to the Next Generation Network (NGN), the Internet Engineering Task Force (IETF) has developed a set of signaling transfer (SIGTRAN) protocol architecture to adapt various signaling messages in the traditional telephone network to Assigned to the IP network. The so-called adaptation refers to the stripping of the original signaling part aimed at the characteristics of the circuit switching network, and repackaging the internal interlayer interface and signaling messages into signaling protocol packets suitable for transmission on the IP network. According to the characteristics of different signaling, different adaptation protocols need to be used...
