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 number as follows: Version x.y.z where: x the f

22、irst 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, updates, etc. z the third digit is incremented

ETSI ETSI TR 122 982 V14.0.0 (2017-03)53GPP TR 22.982 version 14.0.0 Release 141 Scope The objective of this study item is to study requirements and potential new capabilities in 3GPP that need to be standardized for the CAT servic

24、e, especially additional features for roaming and interoperability support. The present document specifies the requirements and technical implements for Customized Alerting Tone (CAT) service in CS domain and the developments in PS domain. Basically this TR is considering voice services, though inte

25、raction with MITe 2 services will be studied. Also Multi-media CAT will be taken into consideration, so the CAT user may experience favourable songs, multi-media clips or other customized alerting tones. 2 References The following documents contain provisions which, through reference in this text, c

29、R 21.905 1 and the following apply. Alerting Tone: An indication that is played to the calling subscriber during establishment of a call or during an established call session indicating one of the following: - that the called subscriber is being alerted. - the progress of communication request (Call

30、 Forward, Call Wait etc.) - any alerting event during a call session Customized Alerting Tone: An Alerting Tone that is customized by the called subscriber or the calling subscriber. A Customized Alerting Tone (CAT) may e.g. be a piece of recorded or composed music, greeting words , voice, advertise

31、ment or video. Customized Alerting Tone Service: A Customized Alerting Tone Service (CAT service) is an operator specific service by which an operator enables the subscriber to customize his alerting tone. CAT Inter-action: is the interaction of the CAT service with other services, e.g. Multiple Ser

32、vices Inter-actioninteraction with Call Forwarding. ETSI ETSI TR 122 982 V14.0.0 (2017-03)63GPP TR 22.982 version 14.0.0 Release 14CAT Inter-working : Multiple Domains Inter-workingis the interworking of a CAT service over different domains or subsystems (CS or IMS) as well as between PLMNs. CAT con

33、tent provider: A service provider that provides a set of Alerting Tones for use as CAT for subscribers of the CAT service. A 3GPP operator may be a CAT content provider. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TR 21.905 1 and the following apply. An abb

34、reviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR 21.905 1. CAT Customized Alerting Tone 4 Suggested CAT service requirements 4.1 Basic functionality of the CAT service The Customized Alerting Tone Service (CAT service) is an opera

35、tor specific service by which an operator enables the subscriber to customize the alerting tone which is played to the calling party. CAT service should not negatively affect the conversation between calling and called parties. The CAT service should at least be able to fulfil the following requirem

36、ents: - The service user can easily subscribe the CAT service, activate the CAT service, and update the settings, e.g. to change his active CAT. - The calling party can experience the CAT set by the called party. - The calling party can experience the CAT set by the calling party. - The calling part

37、ys operator should be able to configure which CAT should have priority, the one set by the called or calling party. The calling partys operator shall be able to take into account the calling partys preferences. - The CAT shall override the default alerting tone towards the calling subscriber. - Each

38、 CAT subscriber has a personal CAT library to store all his CATs. The CAT can be chosen from the CAT library according to rules such as time, calling partys location, called partys location, the identity of the calling and called party. - It shall be possible to inform the user about changes in his

39、CAT service, e.g. close expiry date for the CAT service or a particular CAT content. - The user whose CAT service is active will be charged according to a specified charging mode. - When the called party answers the call, the call channel is set up and the CAT stops. Alternatively, as an operator op

40、tion the content of the CAT may continue to play during the conversation. - When the called party is notified about an incoming call, the called party can send an indication to the CAT service which CAT to play to the calling party. - When the CAT is playing, the calling party can stop it for instan

41、ce by pressing a specific button, then he shall experience the default alerting tone. - When the CAT is playing, the called party can stop it for instance by pressing a specific button, the calling party shall experience another CAT. - It shall be possible for a CAT subscriber to select a CAT, which

42、 content is provided by a CAT content provider, which does not have to be the service provider. ETSI ETSI TR 122 982 V14.0.0 (2017-03)73GPP TR 22.982 version 14.0.0 Release 14Note: the CAT implementation for PLMN based Networks may have a number of issues (CAT unidirectional channel, charging for Ea

43、rly Media, negotiation of early H.324M during the alerting phase, etc.) that should be a subject for Stage 2 standardization 4.2 Normal procedures with successful outcome 4.2.1 Provisioning and Withdrawal The CAT Service can be provisioned and withdrawn by the operator per subscriber. Procedures for

44、 provisioning and withdrawal are out of scope of standardisation 4.2.2 Activation and Deactivation and Update 4.2.2.1 General The service subscriber can activate, de-activate his CAT service. For activation and de-activation, the service subscriber may e.g. employ operator specific USSD commands, SM

45、S, IVR or other means (e.g. customer self-administration via a web-site). 4.2.2.2 Activation When a subscriber activates his CAT Service he needs to specify, which CAT a calling user should experience. After a subscriber has activated his CAT Service a calling user should experience the CAT, that wa

46、s chosen by the subscriber. 4.2.2.3 Deactivation After a subscriber has deactivated his CAT Service a calling user should experience the default alerting tone. 4.2.3 Basic scenarios In the following scenarios, contained in table 1, it is assumed that the called party (B) has activated his CAT Servic

47、e. Calling party (A) is calling B. The calling party has not subscribed and/or activated the CAT service. The Customized Alerting Tone of B is CAT-B. Table 1: Normal Operation Scenarios Called party B (condition) Forwarded-to-party Expected behaviour 4 B, ringing A experiences CAT-B 5 B, busy A expe

48、riences busy indication. 6 B, no answer First A experiences CAT-B and then the no answer indication after Bs no answer timer has expired 7 B, not reachable A experiences not reachable indication In the following scenarios, contained in table 2, it is assumed that only the calling party (A) has activ

49、ated his CAT Service. Calling party (A) is calling B. The called party has not subscribed and/or activated the CAT service. The Customized Alerting Tone of A is CAT-A, ETSI ETSI TR 122 982 V14.0.0 (2017-03)83GPP TR 22.982 version 14.0.0 Release 14Table 2: Normal Operation Scenarios Called party B (condition) Forwarded-to-party Expected behaviour 4 B, ringing Depending on A settings, subscriber A will experience either CAT-A or the default alerting tone. 5 B, busy Depending on A settings, subscriber A will experience either CAT-A or the default
