ETSI ETSI TR 122 982 V13.0.0 (2016-01)53GPP TR 22.982 version 13.0.0 Release 131 Scope The objective of this study it
24、em is to study requirements and potential new capabilities in 3GPP that need to be standardized for the CAT service, especially additional features for roaming and interoperability support. The present document specifies the requirements and technical implements for Customized Alerting Tone (CAT) se
25、rvice in CS domain and the developments in PS domain. Basically this TR is considering voice services, though interaction 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 customize
26、d alerting tones. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

29、 abbreviations 3.1 Definitions For the purposes of the present document, the terms and definitions given in 3GPP TR 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
30、one of the following: - that the called subscriber is being alerted. - the progress of communication request (Call 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 C
31、ustomized Alerting Tone (CAT) may e.g. be a piece of recorded or composed music, greeting words , voice, advertisement 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
32、 his alerting tone. CAT Inter-action: is the interaction of the CAT service with other services, e.g. Multiple Services Inter-actioninteraction with Call Forwarding. ETSI ETSI TR 122 982 V13.0.0 (2016-01)63GPP TR 22.982 version 13.0.0 Release 13CAT Inter-working : Multiple Domains Inter-workingis th
33、e interworking of a CAT service over different domains or subsystems (CS or IMS) as well as between PLMNs. CAT content 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 Abbreviation
34、s For the purposes of the present document, the abbreviations given in TR 21.905 1 and the following apply. An abbreviation 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 requ
35、irements 4.1 Basic functionality of the CAT service The Customized Alerting Tone Service (CAT service) is an operator 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 convers
36、ation between calling and called parties. The CAT service should at least be able to fulfil the following requirements: - 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 CA
37、T set by the called party. - The calling party can experience the CAT set by the calling party. - The calling party“s operator should be able to configure which CAT should have priority, the one set by the called or calling party. The calling party“s operator shall be able to take into account the c
38、alling party“s preferences. - The CAT shall override the default alerting tone towards the calling subscriber. - Each 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 party“s location, called party“s
39、location, the identity of the calling and called party. - It shall be possible to inform the user about changes in his 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. -
40、 When the called party answers the call, the call channel is set up and the CAT stops. Alternatively, as an operator option 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
41、CAT service which CAT to play to the calling party. - When the CAT is playing, the calling party can stop it for instance 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 but
42、ton, the calling party shall experience another CAT. - It shall be possible for a CAT subscriber to select a CAT, which content is provided by a CAT content provider, which does not have to be the service provider.

43、the CAT implementation for PLMN based Networks may have a number of issues (CAT unidirectional channel, charging for Early 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 Prov
44、isioning and Withdrawal The CAT Service can be provisioned and withdrawn by the operator per subscriber. Procedures for 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 CA
45、T service. For activation and de-activation, the service subscriber may e.g. employ operator specific USSD commands, SMS, 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 use
46、r should experience. After a subscriber has activated his CAT Service a calling user should experience the CAT, that was 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
47、 In the following scenarios, contained in table 1, it is assumed that the called party (B) has activated his CAT Service. 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 Scena
48、rios Called party B (condition) Forwarded-to-party Expected behaviour 4 B, ringing A experiences CAT-B 5 B, busy A experiences busy indication. 6 B, no answer First A experiences CAT-B and then the “no answer“ indication after B“s “no answer“ timer has expired 7 B, not reachable A experiences “not r
49、eachable“ indication In the following scenarios, contained in table 2, it is assumed that only the calling party (A) has activated 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 V13.0.0 (2016-01)83GPP TR 22.982 version 13.0.0 Release 13Table 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
