Abstract This standard is
2、 one of a series which defines and describes supplementary services. These services 5 be made available for users with non-ISDN interfaces who access SS7 capable networks and also within the context of an Integrated Services Digital Network (ISDN). This standard describes Calling Name Identification
3、 Presentation which is a terminating service that provides either the name associated with the calling party number or an indication of privacy or unavailability to the called party. i ATIS-1000641.2014 Foreword The information contained in this Foreword is not part of this American National Standar
4、d (ANS) and has not been processed in accordance with ANSIs requirements for an ANS. As such, this Foreword may contain material that has not been subjected to public review or a consensus process. In addition, it does not contain requirements necessary for conformance to the Standard. The Alliance
5、for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between providers, customers, and manufacturers. The Packet Technologies and Systems Committee (PTSC) develops and recommends standards and technical reports related to services, architectures, and signa
6、ling, in addition to related subjects under consideration in other North American and international standards bodies. PTSC coordinates and develops standards and technical reports relevant to telecommunications networks in the U.S., reviews and prepares contributions on such matters for submission t
7、o U.S. ITU-T and U.S. ITU-R Study Groups or other standards organizations, and reviews for acceptability or per contra the positions of other countries in related standards development and takes or recommends appropriate actions. ANSI guidelines specify two categories of requirements: mandatory and
8、recommendation. The mandatory requirements are designated by the word shall and recommendations by the word should. Where both a mandatory requirement and a recommendation are specified for the same criterion, the recommendation represents a goal currently identifiable as having distinct compatibili
9、ty or performance advantages. Suggestions for improvement of this document are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, PTSC, 1200 G Street NW, Suite 500, Washington, DC 20005. At the time of consensus on this document, PTSC, which was responsible for i
10、ts development, had the following leadership: M. Dolly, PTSC Chair (AT a default value for a given jurisdic- tion. The possible values are “private” presentation of the calling partys name is restricted, and “public” presentation of the calling partys name is allowed. 3.1.7 Service provider: This is

16、resentation from the Users Perspective Calling Name Identification Presentation is a terminating service that provides either the name associated with the calling party number or an indication of privacy or unavailability to the called party. If the call has been forwarded prior to the arrival at an
17、 ISDN Calling Name Identification Presentation User, the service can optionally provide the name or names (2 maximum) associated with the original called number or the last redirecting number or indications of privacy or unavailability. 4.1 Description The Calling Name Identification Presentation se
18、rvice provides Name Information or Redirecting Name Information to the called party. The storage and delivery of the calling party name are network functions. The calling party takes no actions to activate, initiate, or in any manner provide Calling Name Identification Presentation. The called party
19、, when subscribed to Calling Name Identification Presentation, automatically receives the Name Information. Delivery of a Calling Name may be affected by a subscriber of the Calling Name Identification Restriction service. For example, a subscriber of Calling Name Identification Restriction who forc
20、es the Calling Name “private” when initiating a call would cause an indication of “private” to be delivered to a Calling Name Identification Presentation subscriber. 4.2 Procedures 4.2.1 Provision/withdrawal The Calling Name Identification Presentation service can be provided on a subscription basis
21、, or as a service provider option, can be provided to some or all users without subscription. The Calling Name Identification Presentation service can be withdrawn for administrative reasons or at the request of the subscriber. As a service provider option, the Calling Name Identification Presentati
22、on service can be offered with several subscription options. For analog service, the options are listed in table 1. For ISDN service, subscription options can be specified per ISDN number, per ISDN number and bearer service, or per interface as listed in table 2. It may be possible for the service p
23、rovider to offer the Calling Name Identification Presentation and Redirecting Name Delivery options combined as a single service or independently. If the Calling Name Identification Presentation service is provided to all users without subscription, the service provider shall assign subscription val
24、ues. 4 ATIS-1000641.2014 4.2.2 Normal Procedures The procedures described below are depicted in Figure 1. Table 1: Subscription options for the Calling Name Identification Presentation service (for analog lines) Subscription options Values Calling Name Identification Presentation Yes Yes and able to
25、 activate/deactivate No Table 2: Subscription options for the Calling Name Identification Presentation service (per ISDN number, per ISDN number and bearer service, or per interface) Subscription options Values Calling Name Identification Presentation Redirecting Name Delivery Yes Yes and able to ac
26、tivate/deactivate No Yes Yes and able to activate/deactivate No 4.2.2.1 Activation/deactivation The activation and deactivation of Calling Name Identification Presentation can be done in two ways based on a subscription option: (a) If the user intends that Name Information be delivered for all calls
27、 then the service is always active when provisioned and remains active until the service provider withdraws the service, (b) If the user requires the capability to activate and deactivate Calling Name Identification Presentation, then the service is active when the user indicates activation to the n
28、et- work and deactivated when the user indicates deactivation to the network. The service provider may combine the 3.1kHz Audio and Speech bearer capabilities for user activation/deactivation. The activation and deactivation of Redirecting Name Delivery can be done in two ways based on a subscriptio
29、n option: (a) If the user intends that Redirecting Name Information is to be delivered for all calls when available, then the service is always active when provisioned and remains active until the service provider withdraws the call, (b) If the user requires the capability to activate and deactivate
30、 Redirecting Name Delivery, then the service is active when the user indicates activation to the network and deactivated when the user indicates deactivation to the network. The service provider may combine the 3.1kHzAudio and Speech bearer capabilities for user activation/deactivation. If a user su
31、bscribes to “Yes and able to activate/deactivate” for both Calling Name Identification Presentation and Redirecting Name Delivery there may be situations where the end user would want to activate or deactivate both features. It may be possible as a service provider option to activate or deactivate b
32、oth Calling Name Identification Presentation and Redirecting Name Delivery with a sin- gle operation, for example, with activation codes to activate or deactivate both delivery features. This prevents users from having to dial two access codes to activate or deactivate both Calling Name Identificati
33、on Presentation and Redirecting Name Delivery. If the service provider supports the option to activate or deactivate both delivery features with a single operation, then the user will not be able to separately activate or deactivate Calling Name Identification Presentation and Redirecting Name Deliv
34、ery when the user subscribes to “Yes and able to activate/deactivate” for both features. 5 ATIS-1000641.2014 4.2.2.2 Invocation and Operation If the called party is subscribed to the Calling Name Identification Presentation service, the called party will receive the Name Information: (non-ISDN) duri
35、ng on-hook alerting (or off-hook alerting for non-ISDN Call Waiting); (ISDN) within six seconds after the user receives a call establishment request. Therefore, the Name Information may be delivered when the user receives the call establishment request or after the user acknowledges the call, even i
36、f the call has reached an active state. The calling party shall receive no notification that Calling Name Identification Presentation is sub- scribed to by the called party or delivered to the called party. 4.2.3 Exceptional Procedures The Calling Name Identification Presentation User will be sent a
37、n indication that Name Information is unavailable if the network does not have Name Information for a specific caller. If the network has been unable to determine the appropriate Name Information to deliver to the called party within six seconds of initially informing the called party of the call, t
38、hen Name Information with an indication of unavailability shall be delivered. The delivery of the Name Information, if disrupted when being delivered to the Calling Name Identification Presentation User, has no effect on the offering of the call. The Calling Name Identification Presentation User may
39、 be sent Name Information that is unrecognizable since the network does not check the transmitted Name Information. The Calling Name Identification Presentation User will not be sent any Name Information after call clearing has been initiated. 6 ATIS-1000641.2014 Figure 1: SDL Diagram for Calling Na
40、me Identification Presentation (Network Perspective) 7 ATIS-1000641.2014 4.3 Interworking Considerations If SS7 connectivity does not exist between the originating exchange and the terminating exchange it shall not be possible to support Calling Name Identification Presentation. 4.4 Capabilities for
41、 Charging It shall be possible for the service provider to charge accurately for this service. 4.5 Interactions with other Supplementary Services 4.5.1 Calling Name Identification Restriction The name of the calling user shall not be presented if the Calling Name presentation status for this call is
42、 private. 4.5.2 ISDN Normal Call Transfer There are no interactions between the Calling Name Identification Presentation service and ISDN Normal Call Transfer (see ATIS-1000632). Each call in the context of ISDN Normal Call Transfer is treated separately for Calling Name Identification Presentation.
43、 4.5.3 ISDN Call Waiting A Calling Name Identification Presentation User who has the ISDN Call Waiting (see ATIS-1000613) service activated will receive Name Information when a call is offered. 4.5.4 ISDN Calling Line Identification Presentation (CLIP) There are no interactions between CLIP (see ATI
44、S-1000625) and Calling Name Identification Presentation. A user may subscribe to both services and receive both CLIP and Name Information. 4.5.5 ISDN Calling Line Identification Restriction (CLIR) There are no interactions between CLIR (see ATIS-1000625) and Calling Name Identification Presentation.
45、 4.5.6 ISDN Multi-level Precedence - Party A calls Party B; - Party A uses three-way calling to call Party C so that Parties A, B, and C are included in a three-way call. In this scenario, Party A is the calling party for both Party B and Party C. Therefore, Party As Name Information should be displ
46、ayed to Party B when Party B is called and to Party C when Party C is called. b) A three-way call is set up as follows: - Party B has the three-way calling feature. Parties B and C subscribe to Name; - Party A calls Party B; - Party B uses three-way calling to call Party C so that Parties A, B, and
47、C are included in a three-way call. 9 ATIS-1000641.2014 In this scenario, Party A is the calling party for Party B, and Party B is the calling party for Party C. Therefore, the Name Information of Party A should be displayed to Party B. The Name Information of Party B should be displayed to Party C.
48、 4.5.11.3 Non-ISDN Multilocation Business Group (MBG) Call Transfer Each call in the context of Call Transfer is treated separately for Calling Name Identification Presentation. Each called party would receive the calling partys Name Information during the alerting phase of each call. 4.5.11.4 Non-I
49、SDN Multilocation Business Group (MBG) Call Waiting Originating (CWO) b) Using a Feature Activation information element with a Calling Name Identification Presentation deactivation feature identifier to toggle the current activation/deactivation status of Calling Name Identification Presentation; c) Using a Facility information element to activate and deactivate Calling Name Identification Presentation. The activation and deactivation of Redirecting Name Delivery can be done by subscription. If the user subscribes to Redirecting Name Delivery “Yes and able to activate/deactiv
