Recommendation ITU-T Y.2214 describes the CMR concept, service requirements and CMR functional models in call serv
9、er-based, IP multimedia subsystem-based and converged network environments. Source Recommendation ITU-T Y.2214 was approved on 22 May 2009 by ITU-T Study Group 13 (2009-2012) under Recommendation ITU-T A.8 procedures. ii Rec. ITU-T Y.2214 (05/2009) FOREWORD The International Telecommunication Union
10、(ITU) is the United Nations 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
11、issuing Recommendations 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
12、 topics. The approval of 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 expres
13、sion “Administration“ is 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 applicabili
14、ty) and compliance with the 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 Rec
15、ommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability
16、of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Rec

25、 multimedia ring services 1 Scope Customized multimedia ring (CMR) is a set of services that allows subscribers to customize the media used for ring tone presentation to the called/calling party. CMR consists of the customized ring-back tone (CRBT) service and the customized ringing tone (CRT) servi
26、ce. From the user point of view, subject to the media capability of the terminals, the user experience of the service is similar across various network environments, but from the service architecture perspective, each environment has its own functional models and requirements. This Recommendation pr
27、ovides: CMR general description; CMR service requirements; CMR functional models in call server-based, IMS-based and converged network environments. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions o
