23、 32.281 version 15.0.0 Release 151 Scope During any phase of a voice or video call, the Online Charging System (OCS) may need to deliver billing/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

24、 need to inform the user about usage states, threshold crossings, offer statuses, reason for call rejection, alerts about low balances, etc. In Circuit Switched (CS) domain, online charging of a voice session is performed using Customised Applications for Mobile network Enhanced Logic (CAMEL) mechan

25、isms. In order to deliver in-session notifications or to interact with the end user, OCS can use CAMEL messages such as: Play Announcement, Prompt and Collect, Connect to Resource, Establish Temporary Connection. Such notifications can be delivered pre-, mid- or post-call. However, in IMS and MMTel

26、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, announcement 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 sess

27、ion may be connected to a resource that delivers an announcement. The Announcement service in this specification provides announcement capabilities 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

28、charging/billing related notifications.

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 provide

36、s the mechanisms to support operator specific services even when roaming outside HPLMN. circuit switched domain: domain within GSM / UMTS in which information is transferred in circuit switched mode. Credit-Control: mechanism which directly interacts in real-time with an account and controls or moni

37、tors the charges, related to the service usage. Credit-Control is a process of: checking if credit is available, credit reservation, deduction of credit from the end user account when service is completed and refunding of reserved credit not used. online charging: charging mechanism where charging i

38、nformation can affect, in real-time, the service rendered and therefore a direct interaction of the charging mechanism with bearer/session/service control is required. Online Charging System: the entity that performs real-time Credit-Control. Its functionality includes transaction handling, rating,

39、online correlation and management of subscriber accounts/balances. 3.2 Symbols For the purposes of the present document, the following symbols apply: Symbol format Cr Reference Point between an AS and an MRFC for media control.
