Embodiment Construction
[0038] Such as figure 1 As shown, 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 IP signaling across different networks set on the network boundary 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 the role of th...
