Cooperative call processing across public and private intelligent networks

摘要

A wide range of advanced call processing services are optimally provided through a cooperative effort between public and private intelligent networks. Service control logic in the public network interacts with service control logic in the private network. The cooperative call processing exploits the best service features from both environments. More specifically, a logical relationship is established over an end-to-end, service logic communication path between the service control elements of both networks using a very small set of operation procedures. Using that set of operational procedures, either network's service control logic requests and receives a service feature orchestrated entirely by the other network's service logic. In this way, specific service features making up a requested service may be provided by the network best suited to perform a particular service feature. Since neither network needs to control or even know how the other network performs its assigned service feature, the integrity and simplicity of each network's control logic and protocols are preserved.
