SIP servlet dialogue handling for NGN Service Capability Interaction Manager

The Next-Generation Network (NGN) is currently under development. Supporting 3
^rd
party SIP applications on NGNs is necessary in order to improve the services provided to NGN subscribers. We propose using certain function in order to fully open up NGN and allow 3
^rd
party service providers to offer services running on SIP application servers. If the deployment objectives of our proposed functions are taken into consideration, it is necessary to focus on the Service Capability Interaction Manager (SCIM). We propose that the SLIM acts as a function point to coordinate application service runtime execution between SIP application servers provided by both 3
^rd
party service providers and telcos.
