Enabling creation of converged internet protocol multimedia subsystem services by third-party application developers using session initiation protocol support

A computer program product comprising a tangible computer readable recordable storage medium including computer usable program code, said computer program product including:

• computer usable program code for instantiating a plurality of pure operator type rules within a domain of a telecommunications operator and a plurality of pure application type rules within a domain of a third party telecommunications application provider, said plurality of pure operator type rules and said plurality of pure application type rules being associated with a composite service;
• computer usable program code for establishing a plurality of network components to transmit given events of a plurality of protocol-level events to at least one of said domain of said telecommunications operator and said domain of said third party telecommunications application provider;
• and
• computer usable program code for deploying said composite service in an execution engine of said third party telecommunications application provider.

An apparatus comprising:

• a memory;
• and
• at least one processor, coupled to said memory, and operative to:
• instantiate a plurality of pure operator type rules within a domain of a telecommunications operator and a plurality of pure application type rules within a domain of a third party telecommunications application provider, said plurality of pure operator type rules and said plurality of pure application type rules being associated with a composite service;
• establish a plurality of network components to transmit given events of a plurality of protocol-level events to at least one of said domain of said telecommunications operator and said domain of said third party telecommunications application provider;
• and
• deploy said composite service in an execution engine of said third party telecommunications application provider.
