The scope of this TR is to capture the results of a feasibility study in the needs of identifying IMS communication services with and in the need of the IMS communication service identifier.
This technical report contains the results into a study on the communication service identifier with a focus on the following aspects:
a frame work description for the usage and applicability of the communication service identifier and its relationship with the PSI and other existing IMS mechanisms;
identifying the architectural requirements for a communication service identifier that enable the usage scenarios identified in the above justification section;
identifying requirements on compatibility and evolution of a communication service in relation to the communication service identifier;
identify the methods for administrative procedures for a communication service identifier, including the requirements upon when a service identifier value is required to be allocated;
In addition alternative mechanisms to identify communication services may be identified.
