ITU-T J.367 (06/2008) FOREWORD The International Telecommunication Union (ITU) is the United Nati
4、ons specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations
5、on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of
6、 ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is
7、 used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with t
8、he Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required o

15、008) 1 Recommendation ITU-T J.367 IPCablecom2 presence specification 1 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 willi
16、ngness 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 normativ
17、e 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
18、 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 a
19、nd 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. 2 References 2.1 Normative References The following ITU-T Recommen

40、 to mean “a technology intended for use in the development, deployment or operation of a service“. Examples of OMA Enablers are Device Management, Push-to-Talk over Cellular (PoC), Presence SIMPLE, and XML Document Management (XDM). 3.3 fetcher: A form of Watcher that has asked the Presence Service
41、for the Presence Information of one or more Presentities, but is not requesting a Notification from the Presence Service of (future) changes in a Presentitys Presence Information OMA RD-PRS. 3.4 notification: A message sent from the Presence Service to a Subscriber when there is a change in the Pres
42、ence Information of some Presentity of interest, as recorded in one or more Subscriptions OMA RD-PRS. 4 Rec. ITU-T J.367 (06/2008) 3.5 presence information: Dynamic set of information pertaining to a Presentity that may include Presence Information Elements such as the status, reachability, willingn
43、ess, and capabilities of that Presentity OMA RD-PRS. 3.6 presence information element: A basic unit of Presence Information OMA RD-PRS. 3.7 presence list: A list of presentities that can have their individual states subscribed to with a single subscription request (e.g., a subscription list). 3.8 pr
44、esence server: A logical entity that receives Presence Information from a multitude of Presence Sources pertaining to the Presentities it serves and makes this information available to Watchers according to the rules associated with those Presentities OMA RD-PRS. 3.9 presence service: The capability

46、he Presence Server. 3GPP Presence User Agents, Presence Network Agents, and Presence External Agents are examples of Presence Sources OMA RD-PRS. 3.11 presentity: A logical entity that has Presence Information associated with it. This Presence Information may be composed of a multitude of Presence S
47、ources. A Presentity is most commonly a reference for a person, although it may represent a role such as “help desk“ or a resource such as “conference room #27“. Presentities are generally referenced by distinguished names, such as ““ or by phone numbers like “+19724735455“. In SIMPLE, presentities
48、are generally referenced using a sip:, pres: or tel: URL OMA RD-PRS. 3.12 subscriber: A form of watcher that has asked the Presence service to notify it immediately of changes in the Presence Information of one or more presentities OMA RD-PRS. 3.13 subscription: The information kept by the presence
