Signaling Tunneling Protocol

This product can be used as the large-capacity signaling transfer point (STP) or the independent signaling gateway. When acting as the STP, this product implements all functions of the traditionalnarrowband STP, that is, processing and transferring the SS7 signaling messages in the PSTN of traditional circuit domain. When acting as the independent signaling gateway, this product is located atthe edge access layer of the NGN. It uses the Signaling Transport (SIGTRAN) and Signaling System No.7 (SS7) protocols. The SG7000 achieves the interworking between the public switched telephone network(PSTN)/public land mobile network (PLMN) and NGN through SS7, by cooperating with other components in this network including the softswitch device and IP-based database devices, like IP-SCP, IP-HLR,and IP-SMSC.
Along with the opening-up of the telecom market and coexistence of multiple operators, the competition among operators is more serious. The competition steers from the simple price toproviding high-quality and versatile services, exploring customer potential demands, and classifying customer groups. The investment focus diverts from equipment to value-added services and networkoptimization.
Customers have more and more choices. In this case, how to provide better and timely services to customers to raise customer satisfaction and obtain better economic and social benefits isthe most concerned problem to operators.
Under this background, from the viewpoint of cost saving, network reuse, and service innovation, operators put forward more specific requirements on theintegration of different networks and service development:
 Providing differentiated and competitive services
 Providing various services to new customers and upgrading services for previous customers Fast introducing new services
 Making the best use of the original network resources
 Providing industrial and enterprise solutions concerning customer benefit
 Reducing maintenance cost...
