19、GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version n
20、umber as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
21、updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 132 281 V14.0.0 (2017-05)53GPP TS 32.281 version 14.0.0 Release 141 Scope During any phase of a voice or video call, the Online Charging System (OCS) may need to deliver bi
22、lling/charging in-session notifications to the end user via announcements as part of the rating, balance management and billing process. For example, the OCS may need to inform the user about usage states, threshold crossings, offer statuses, reason for call rejection, alerts about low balances, etc
23、. In Circuit Switched (CS) domain, online charging of a voice session is performed using Customised Applications for Mobile network Enhanced Logic (CAMEL) mechanisms. In order to deliver in-session notifications or to interact with the end user, OCS can use CAMEL messages such as: Play Announcement,
24、 Prompt and Collect, Connect to Resource, Establish Temporary Connection. Such notifications can be delivered pre-, mid- or post-call. However, in IMS and MMTel charging defined in TS 32.260 20 and TS 32.275 35 as well as in Diameter Credit-Control Application (DCCA) defined in RFC 4006 402, announc
25、ement capabilities, available at the OCS level, are limited to redirection of a session to a given SIP URI at completion of the session. When redirected the session may be connected to a resource that delivers an announcement. The Announcement service in this specification provides announcement capa
26、bilities for use in a Diameter based online charging session. The OCS is able to specify that a given announcement be played to a call party in order to deliver charging/billing related notifications.

34、pply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 100. CAMEL: network feature that provides the mechanisms to support operator specific services even when roaming outside HPLMN. circuit switched domain: domain within GSM / UMTS i
35、n which information is transferred in circuit switched mode. Credit-Control: mechanism which directly interacts in real-time with an account and controls or monitors the charges, related to the service usage. Credit-Control is a process of: checking if credit is available, credit reservation, deduct
36、ion of credit from the end user account when service is completed and refunding of reserved credit not used. online charging: charging mechanism where charging information can affect, in real-time, the service rendered and therefore a direct interaction of the charging mechanism with bearer/session/
37、service control is required. Online Charging System: the entity that performs real-time Credit-Control. Its functionality includes transaction handling, rating, online correlation and management of subscriber accounts/balances. 3.2 Symbols For the purposes of the present document, the following symb
