Patent ID: 7864936

Claim:
A method of processing a network communication in order to avoid or minimize the cost of inter-domain stateful connections between application servers (ASs) and serving call state control function (S-CSCF) nodes in a network with multiple domains, said method comprising: receiving a network communication by an S-CSCF node having a co-located S-CSCF service logic and application server, and processing the network communication on a processor contained within the co-located S-CSCF service logic and application server to avoid or minimize the cost of stateful inter-domain connections between the application server and the S-CSCF by providing intra-domain connections between the AS and the S-CSCF, wherein the network includes a network operator administration domain and an mobile virtual network operator (MVNO) service domain, and wherein the S-CSCF logic and AS are maintained in the same domain, thereby avoiding or minimizing the cost of stateful inter-domain connections between the ASs and the S-CSCF by providing intra-domain connections between the AS and the S-CSCF.
