11、tions 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 Recommendation
12、s 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
13、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 expression “Administration“
14、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 applicability) and compliance wi
15、th 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 Recommendation is requir
16、ed of any party. INTELLECTUAL PROPERTY RIGHTSITU 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 of claimed Intellectua
17、l 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 not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. Howev

41、ion diversion (CDIV) service could enable communications addressed to a user to be diverted to another destination. The description and document structure of this Recommendation are based on ETSI TS 124 604. Procedures for the CDIV application server (AS) regarding operator determined barring (ODB)
42、are defined in ETSI TS 124 315. 4.2 Description 4.2.1 General description 4.2.1.1 Service description The service description of the following CDIV services: communication forwarding unconditional (CFU), communication forwarding busy (CFB), communication forwarding no reply (CFNR) and communication
43、deflection (CD), is based on that of public switched telephone network (PSTN)/ integrated service data network (ISDN) supplementary services. The communication forwarding on not logged-in (CFNL) service is a CDIV service based on requirements for IP based networks and the communication forwarding on
44、 subscriber not reachable (CFNRc) service is based on requirements for mobile networks. In addition, communication diversion notification (CDIVN) is a CDIV service providing the user with the capability to receive notifications about all diverted communications (CFU, CFB, CFNR, CD, CFNRc and CFNL).
45、Generally the following requirements are expected to be fulfilled: the service provides for the user or the network to identify an alternative destination for an IP multimedia session or individual media of an IP multimedia session; the service provides for redirection to be initiated at various sta
46、ges of an IP multimedia session. For example: prior to the setting up of an IP multimedia session; during the initial request for an IP multimedia session (CFU); during the establishment of an IP multimedia session (CD). the service provides redirection to be applied for all multimedia sessions unco
47、nditionally or redirection can be caused by any of a set list of events or conditions. Typical causes could be: identity of the originating user; presence of the originating or destination party; if the destination party is already in a session (CFB); if the destination party is unreachable or unava
48、ilable in some other way (CFNL, CFNR, CFNRc); if the destination party does not respond (CFNR); Rec. ITU-T Q.3616 (10/2015) 5 after a specified alerting interval (CFNR); the users preference on routing for specific IP multimedia session based on the capabilities of multiple user equipments (UEs) sha
49、ring the same IP multimedia subsystem (IMS) service subscription; the sending party, the receiving party or the network on their behalf, may initiate redirection to alternative destinations; the service provides for the user to subscribe to receive notifications of his/her communications diversions as dictated by the above requirements. The user will also be able to control: if he/she wants to be notified of all or of a particular subset of his/her comm
