18、29 Page 5 GSM 02.81 version 5.1.0: January 1998 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) of the European Telecommunications Standards Institute (ETSI). This GTS describes line identification Supplementary
19、Services (stage 1) within the digital cellular telecommunications system. The contents of this GTS are subject to continuing work within SMG and may change following formal SMG approval. Should SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of rele
20、ase date and an increase in version number as follows: Version 5.x.y where: y the third digit is incremented when editorial only changes have been incorporated in the specificat ion; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, e
21、tc. The specification from which this GTS has been derived was originally based on CEPT documentation, hence the presentation of this GTS is not in accordance with the ETSVPNE rules. STD-ETSI GSM D2.8L-ENGL 1798 W 3900855 02b583b Db5 Page 7 GSM 02.81 version 5.1.0: January 1998 O Scope This Global S
22、ystem for Mobile communications Technical Specification (GTS) describes the Supplementary Services belonging to the group Line Identification Supplementary Services. The general aspects, including definitions and recommended provision, of the description of the GSM Supplementary Services are given i
23、n GSM 02.04. The group of Line Identification Supplementary Services is divided into the following four Supplementary Services : CLIP - CLIR - COLP - COLR - Calling line identification presentation (clause 1); Calling line identification restriction (clause 2); Connected line identification presenta
24、tion (clause 3); Connected line identification restriction (clause 4). Definitlon of line identity: The line identity is made up of a number of information units: - the subscribers national ISDN/MSISDN number (MSISDN number is the number stored in the VLR); - the country code; - optionally, subaddre
25、ss information. The GSM PLMN cannot be responsible for the content of this subaddress. (For definition of the subaddress see CCITT Recommendation E1 64 131 subclause 11.2). In a full ISDN environment, the line identity shall include all the address information necessary to unambiguously identify a s
26、ubscriber. The calling line identity is the line identity of the calling party. The connected line identity is the line identity of the connected party. If for the line identity of the calling party or the connected party additional line identification is received (additional calling party/connected
27、 party number) in a GSM PLMN this additional line identification shall be used for the presentation purpose of the line identification presentation services. Definition of Presentation and Screening Indicators: In addition to or instead of the line identity, the network may give a Presentation Indic
28、ator (Pi) and/or a Screening Indicator (SI) to the served subscriber. The following information may be given: - Presentation Indicator showing: a) presentation allowed, or b) presentation restricted, or c) number not available due to interworking; - Screening Indicator showing: a) b) c) network prov
29、ided. user provided, verified and passed, or user provided, not screened, or If the line identity is that of a GSM PLMN subscriber, then: the national number and the country code shall always be provided by the network; the subaddress shall only be included if it is provided by the user (or user equ
30、ipment); the screening indicator shall indicate “network provided“ Previous page is blank 1 STD=ETSI GSM 02-81-ENGL 1998 M 3400855 02b5837 TTL .

34、he line identity of the calling party. 1.2 Description 1.2.1 Description This Supplementary Service provides for the ability to indicate the line identity of the calling party to the called party. The network shall deliver the calling line identity to the called party at call Set-up time, regardless
35、 of the terminal capability to handle the information. 1.2.2 Applicability to telecommunication services The applicability of this Supplementary Service is defined in GSM 02.04 (ETC 300 503). 1.3 Normal procedures with successful outcome 1.3.1 Provision This Supplementary Service is provisioned for
36、all Basic Services subscribed to and to which it is applicable, .e. not provisioned for any subset of these Basic Services. Override category within a PLMN Override category within an iSDN/PLMN. Depending on national regulations, some networks may define categories of subscribers that have the abili
37、ty to override the presentation restriction (CLIR, ch 2) and have the calling line identity presented (e.g., the police). The ability to have such override category is a national option. Override category between a PLMN and a network providing calling line identification restriction Override categor
38、y between ISDNPLMNs. When a call originates in one ISDN/PLMN and terminates in another ISDNPLMN and the CLIR Supplementary Service is applied, the rules and regulations of the destination network shall apply. For example, the override category may not be applicable in the originating network but may
39、 be applicable in the destination network. In this STD-ETSI GSM 02-81-ENGL 1778 = 3400835 02b5838 938 Page 9 GSM 02.81 version 5.1.0: January 1998 situation, a call with the CLIR Supplementary Service applied can still be overridden in the destination network. The override category is only applicabl
40、e within the HPLMN country. 1.3.2 Withdrawal The CLIP Supplementary Service shall be withdrawn at the customers request or for administrative reasons. 1.3.5 Activation The CLIP Supplementary Service is activated as a result of provision. 1.3.6 Deactivation The CLIP Supplementary Service is deactivat
41、ed as a result of withdrawal. 1.3.7 invocation The network shall automatically invoke the CLIP Supplementary Service in the call Set-up phase. 1.3.8 Normal operation with successful outcome A user who has subscribed to the CLIP Supplementary Service and receives a call shall also receive the line id
42、entity of the calling party. In addition to or instead of the calling line identity, the subscriber may be given a Presentation Indicator and/or a Screening Indicator with the relevant information. 1.3.1 1 interrogation Status check The mobile subscriber can request the status of the Supplementary S
43、ervice and be informed if the service is provided to her. 1.4 Exceptional procedures or unsuccessful outcome If the CLIR Supplementary Service is applicable to the call, then the called PLMN user shall receive an indication that the calling line identity is not available because of restriction. NOTE
44、: See also subclause 1.3.1 (override category). In some interworking situations in which the connection is not completely supported by the sufficient signalling capability, then the called PLMN user shall receive an indication that the calling line identity is not available. For an international cal
45、l in which the originating network does not provide the calling line identity, then the called PLMN user shall receive an indication that the calling line identity is not available. 1.5 Alternate procedures None identified. 1.6 Interactions with other Supplementary Services 1.6.81.2 Calling line ide
46、ntification restriction The CLIR Supplementary Service shall take precedence over the CLIP Supplementary Service. Page 10 GSM 02.81 version 5.1.0: January 1998 The CLIP Supplementary Service can take precedence over the CLIR Supplementary Service when the called user has an override category. The av
47、ailability of the override category as well as the handling of calling line identity parameters for the override category is a national matter. 1.6.82.1 Call forwardlng uncondltlonal When a call has been forwarded and the forwarded-to user has been provided with the CLIP Supplementary Service, the f
48、orwarded-to user shall receive the number of the original calling user, if this calling user has not subscribed to or invoked the CLIR Supplementary Service. 1.6.82.2 Call forwarding on mobile subscriber busy Same as the interaction with call forwarding unconditional. 1.6.82.3 Call forwarding on no
49、reply Same as the interaction with call forwarding unconditional. 1.6.82.4 Call forwarding on mobile subscriber not reachable Same as the interaction with call forwarding unconditional. 1 A83.1 Call Waiting If the served mobile subscriber is provisioned with the CLIP service, the notification of an incoming (waiting) call offered to that subscriber shall include the calling line identity, as for a normal call. 1.7 Interworking conslderatlons According to national network specific rules, the CLIP Supplementary Services need not be applicabl
