2、ement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of TIAIEIA from manufacturing or selling products not confor
3、ming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TIAIEIA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by TIAIEIA in accord
4、ance with the American National Standards Institute (ANSI) patent policy. By such action, TIAIEIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. TIA STANDARDS TIA Standards contain information deemed to b
5、e of technical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of a TIAIEIA Standard. TIA Standards should be reviewed on an annual b
6、asis by the formulating Committee and a decision made on whether to proceed to develop a TIAIEIA Standard on this subject. TIA Standards must be cancelled by the Committee and removed from the TIAIEIA Standards Catalog before the end of their third year of existence. Publication of this TIA Standard
7、 for trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this TIA Standard for comment shall not continue beyond 60 months from the date of publication. It is expected that following this 36 month period, this TIA Standard, revised as necessary, wi
8、ll be submitted to the American National Standards Institute for approval as an American National Standard.

This document describes intersystem operations for the implementation of Calling Name Presentation (CN
11、AP) and Calling Name Restriction (CNAR) services. Not all of the CNAP and CNAR features and corresponding intersystem operations can be implemented in many public networks because of regulatory constraints, limitations of interconnecting networks, or other restrictions. Examples of such features inc
12、lude: CNAR Blocking Toggle; the use of CNAR feature activation or deactivation codes that are distinct from corresponding Calling Number Restriction (CNIR) feature activation or deactivation codes; and the use of distinct default presentation status for CNIR and CNAR. There are circumstances in whic
13、h a CNAP subscriber roaming in a CNAP capable system will be provided with an indication that a calling party name is for a call that is being redirected to that subscriber, even though the calling party number has been received by the subscribers Home System and the calling party name is available
14、for retrieval from the appropriate database (e.g., a Line Information Database). These circumstances are limited to cases in which: b. Before redirection, the call had been directed to an MS from the same Home System as the Home System of the subscriber to which the call is being redirected. The cal
15、l is redirected by the Serving MSC, rather than by the Originating MSC. Similarly, in some cases in which these circumstances apply, if the subscriber to which the call is redirected is a CNIP subscriber, that subscriber may receive an indication that a calling party number is not available even tho
16、ugh the calling party number has been received by the subscribers Home System and the Serving System supports CNIP. These limitations have been accepted because the only proposal that addressed these limitations would impact call delivery for all calls, including calls to MSs that are not subscribed
17、 to CNAP (or CNIP), and because it is assumed that circumstances in which these limitations might interfere with the proper operation of CNAP (or CNIP) will be rare. vii Assumptions TIA-764 Revision Date Remarks O April 1998 Initial Publication 1 Il t Revision History viii TIA-764 1 2 3 4 5 6 7 8 9

27、New for TINEIA-664 Section 5) Calling Name Presentation (CNAP) provides the name identification of the calling party (e.g., personal name, company name, “restricted”, “not available”) to the called subscriber. The calling name identification (CNA) may be provided to the terminating network by the or
28、iginating network or the terminating network may retrieve it or derive it using the calling number identification (CNI) which is generally provided to the terminating network from the originating network. The CNA is considered public when presentation of the calling name is allowed, and private when
29、 presentation of the calling name is restricted. Optionally, the date and time of the call may also be provided to the called subscriber. Redirecting Name Delivery (RND) is a CNAP subscription option. When CNAP with RND is active and a call has been forwarded, CNAP provides the CNA of the last redir
30、ecting party and the original calling party to the called subscriber. CNAP does not impact a subscribers ability to originate calls or to receive calls. Applicability to Telecommunications Services CNAP is applicable to voice and circuit switched data telecommunications services. 5.A.1 Normal Proced
31、ures With Successful Outcome Authorization CNAP may be generally available or may be provided after pre-arrangement with the service provider. 3 Calling Name Presentation (CNAP) TINEIA-664 Modifications TIA-764 The authorization may have the following subscription options: I Subscription Options CNA
32、P Activation Values Permanent. CNAP is active while authorized. Demand. The subscriber is authorized to control the activation and de-activation of CNAP. Not subscribed. In the case of forwarded calls, it shall be the CNA associated with the calling party which is presented to the mobile station (MS
33、). Subscribed. In the case of forwarded calls, the CNA of the last redirecting party and the original calling party are presented to the MS. Table 2-1 : CNAP Subscription Options De-Authorization CNAP may be withdrawn at the subscribers request or for administrative reasons. Registration CNAP has no
34、 registration. De- Registration CNAP has no de-registration. Activation CNAP is activated upon authorization for a Permanent CNAP Activation subscriber. CNAP may also be activated by a Demand Activation authorized subscriber specifying a feature code, as in: * FC+ I SENDI . Successful demand activat
35、ion shall be indicated with feature confirmation treatment.

Invocation CNAP is invoked when the CNI associated with an incoming call is available, the called subscriber has CNAP active and the call can be presente
38、d to the called MS. CNAP is subject to the restrictions of the CNA and the serving service provider. Normal Operation With Successful Outcome When the CNAP service is invoked, the destination network shall send the CNA to the MS during alerting on incoming calls. It may be possible to present the CN
39、A in the subscribers preferred language. In the event of call forwarding when CNAP and RND are active, the CNA of the last redirecting party and the original calling party are presented to the MS. CNI may be used to derive the CNA. Only a network-provided or user-provided (passed screening) calling
40、party number shall be used to derive the calling party name. Only a network-provided redirecting party number shall be used to derive the redirecting party name. Refer to TIA/EIA-664 “Calling Number Identification Presentation (CNIP)” for a description of the different types of CNI. Call Detail Reco
41、rd The system should record call detail information for the following: a. b. c. CNAP activation activities and events. CNAP de-activation activities and events.
