22、TRICTION (Geneva, 1996) 1 Definition calling name identification restriction (CNIR): Is a supplementary service offered to the calling party to restrict presentation of name information associated with the calling party to the called party. 2 Description Calling name identification restriction is an
23、 originating service that allows a user to alter the network stored or subscribed privacy status associated with the users calling name. 2.1 General description Calling name identification restriction is an originating service that provides a calling party the means to influence the delivery of the
24、calling partys name. There are three methods of influencing the privacy status of the calling name: 1) 2) Subscription to a network stored value of “private“ or “public“. Modification of the network stored value fiom “private to public“ or from “public to private“ on a per call basis. Once the call
25、is initiated, the calling name resumes its network stored status for subsequent calls. Explicitly stating whether the calling name should be “private“ or “public“ on a per call basis. Once the call is initiated, the calling name resumes its network stored status for subsequent calls. If the presenta
26、tion status of the calling name is “private“ through any of the above methods, the called party shall not receive the calling name, but may receive an indication of privacy. 3) 2.2 Specific terminology For the purposes of this Recommendation, the following definitions apply. 2.2.1 calling name: Info
27、rmation associated with a specific calling party number. The maximum length is at least 15 characters and may be up to 50 characters. The exact length, format and character set of the calling name to be delivered is a service provider option. 2.2.2 calling name identification user: This is the party
28、 who subscribes to the calling name identification restriction service and is the calling party. 2.2.3 network: In this description, network refers to all the TSDN telecommunications equipment that has any part in processing a call or a supplementary service for the user referred to. It does not inc
29、lude the ISDN terminal. 2.2.4 service provider: This is a company, organization, administration, business, etc. that sells, administers, charges for etc. the service. The service provider may or may not be the provider of the network. Recommendation 1.251.10 (07/96) 1 ITU-T RECMN*I.251= 10 76 W 4862
30、591 0637938 T54 = 3 Procedures 3.1 Provision/withdrawal The calling name identification restriction service can be provided on a subscription basis, or as a service provider option, can be provided to some or all users without subscription. (This service provider option would allow all users to be g
31、iven a network stored status of “private“.) The calling name identification restriction service can be withdrawn for administrative reasons or at the request of the subscriber. As a service provider option, the calling name identification restriction service can be offered with several subscription
32、options. The options apply separately to each ISDN number per ISDN number and bearer service, or per interface as listed in Table 1. The service provider may not differentiate between 3.1 kHz audio and speech bearer capabilities for the purpose of assigning subscription options. If the calling name
33、identification restriction service is provided to all users without subscription, the service provider shall assign subscription values. TABLE 1A.251.10 Subscription options for the calling name identification restriction service Subscription options Network stored status Switch to the opposite of t
34、he subscribed or network stored status Force calling name private Force calling name public Values “Private“ “Public“ No Y es No Yes NO Yes 3.2 Normal procedures 3.2.1 Activation/deactivation/registration 3.2.1.1 Network stored status of “private“ or “public“ When the user subscribes to a network st
35、ored status of “private“ or “public“, the service is active and the network stored status remains as either “private“ or “public“ until the user makes a change with the service provider. 3.2.1.2 This service is activated by subscription with the service provider. See below for per call invocation. 3
36、.2.1.3 This service is activated by subscription with the service provider. See below for per call invocation. 3.2.2 Invocation and operation The calling party receives no notification when either a calling name or an indication that the calling name is unavailable or restricted is delivered to a ca
37、lled party. Modification of the network stored value Force name information private (or public) 2 Recommendation 1.251.10 (07/96) ITU-T RECMN*Im25L. LO 76 4862573 ObL79L9 990 m 3.2.2.1 The user takes no action to invoke this method. Network stored status of “private“ or “public“ 3.2.2.2 Modification
38、 of the network stored value The user indicates to the network that their calling name presentation status for this one call is to be the opposite of the network stored value. The user receives an indication from the network that the request has been accepted. The users request for the opposite of t
39、he network stored value becomes part of the call information when the user initiates this one call. 3.2.2.3 The user indicates to the network that the calling name presentation status is to be “private“ or “public“ for this one call regardless of the network stored value. The user receives an indica
40、tion from the network that the request has been accepted. The users request for a “private“ or “public“ presentation status becomes part of the call information when the user initiates this one call Force name information private (or public) 3.3 Exceptional procedures If the user requests the networ
41、k to force the calling name “private“ and the network stored value is “private“, no error indication will be given to the user. If the user requests the network to force the calling name “public“ and the network stored value is “public“, no error indication will be given to the user. The user may mo
42、di9 the presentation status of the name once only per call. If the user requests the network to force the calling name to “private“ and to “public“ for the same call, then the associated call attempt will fail. If the user requests the network to switch the network stored value to its opposite and a
43、lso requests to force the calling name to “private“ or “public“ for the same call, then the associated call attempt will fail. If a user attempts to modi the network stored status, to force the calling name “private“, or to force the calling name “public“ and is not subscribed, then the user will re
44、ceive an error indication. If the user requests the network to switch the network stored value to its opposite and then again requests the network to switch the stored value to its opposite prior to making a call, the associated call attempt by the user will be failed by the network. 4 Network capab
45、ilities for charging This Recornmendation does not cover charging principles. Future Recommendations in the D-Series are expected to contain that information. It shall be possible for the service provider to charge the subscriber accurately for this service. 5 Interworking considerations 5.1 Interwo
46、rking with non-ISDN networks When a call transits or terminates on a non-ISDN network, it cannot be assured that the CNIR privacy status can be carried to the destination network. As a network option, the originating network shall have the possibility to restrict any information concerning the calli
47、ng party name from being sent to the destination network when CNIR is applicable. If a destination network receives a calling party name without any indication of presentation allowed or restricted, then the destination network will act according to its own rules and regulations. Recommendation 1.25
48、1.10 (07196) 3 5.2 On calls from the public ISDN to a private ISDN, the public ISDN can restrict any calling party name information from being sent to the private ISDN. On calls fi-om a private ISDN, the private ISDN can indicate that the CNIR supplementary service has been invoked. Interworking wit
