Abstract:
1. A system for mediating a first network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices with an alternative network to create a hybrid network, said system comprising: a first network; an alternative network; a plurality of application servers (ASs) located in both the first network and the alternative network; logic located in the AS to define a service and corresponding service request code to utilize at least a subset of capabilities provided by said alternative network; logic located in the AS to provision the S-CSCF to identify and receive an alternative network service request message from a UE, said logic including logic to provide a call model based on a cost function, wherein the call model having at least one filter code to associate said alternative network service code with at least one application server (AS) dedicated to serving alternative network service requests, said AS being responsive to service point triggers (SPTs); wherein said AS having logic to determine whether to use said alternative network or said first network based on a cost function, being in communication with and capable of controlling delivery of at least a subset of services provided by said alternative network and creating a hybrid network of said first network and said alternative network.
