scope:

This Recommendation adds the Presence functionality to the IPCablecom2 architecture. This enables the exchange of dynamic information about the state of a logical entity (e.g., person, device) and its availability and willingness to communicate or to share. This information can be exploited, for example, by application servers to optimize or customize services. This Recommendation describes the IPCablecom2 Presence architecture that is aligned with the OMA Presence service. This Recommendation also adopts the normative requirements from the relevant OMA specifications and identifies the exceptions where applicable (clause 7).

It is an important objective of this work that interoperability between IPCablecom 2.0 and 3GPP IMS is provided. IPCablecom 2.0 is based upon 3GPP IMS, but includes additional functionality necessary to meet the requirements of cable operators. Recognizing developing converged solutions for wireless, wireline, and cable, it is expected that further development of IPCablecom 2.0 will continue to monitor and contribute to IMS developments in 3GPP, with the aim of alignment of 3GPP IMS and IPCablecom 2.0.

NOTE - The structure and content of this Recommendation have been organized for ease of use by those familiar with the original source material; as such, the usual style of ITU-T recommendations has not been applied.
