13、echnical Specification (GTS) has been produced by the Special Mobile Group (SMG) of the European Telecommunications Standards Institute (ETSI). This GTS defines the stage 2 of the line identification supplementary services for the Digital cellular telecommunications system. The contents of this GTS
14、are subject to continuing work within SMG and may change following formal SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: 5 indicates GSM Rele

16、ed was originally based on CEPT documentation, hence the presentation of this GTS may not be entirely in accordance with the ETSVPNE rules.

17、ription of the call identification supplementary services. The group line identification supplementary services are divided into the following four supplementary services: - Calling line identification presentation CLIP (clause 1); - Calling line identification restriction CLIR (clause 2); - Connect
18、ed line identification presentation COLP (clause 3); - Connected line identification restriction COLR (clause 4). o. 1 Normative references This specification incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate plac
19、es in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this specification only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred
20、 to applies. GSM 01.04 (ETR 350): “Digital cellular telecommunications system (Phase 2+); Abbreviations and acronyms“.

21、Definition of line identity The line identity is made up of the following information units: - - Optionally subaddress information. For mobile originated calls, the ISDNNSISDN shall always be provided within the network. The subaddress shall only be included if it is provided by the user (or user eq
22、uipment). The calling line identity is the line identity of the calling party. The connected line identity is the line identity of the connected party. The subscribers international ISDN/MSISDN number; The additional calling line identity provides additional line information for the purpose of the c
23、alling line identification presentation service (CLIP). The additional connected line identity provides additional line information for the purpose of the connected line identification presentation service (COLP). For mobile originating calls the user (or user equipment) has no possibility to provid
24、e an additional line identity. For mobile terminating calls the user (or user equipment) has no possibility to provide an additional connected line identity.

25、 addition to, or instead of, the line identity or additional line identity, the network may send a presentation indicator (Pi) and/or a screening indicator (SI) or additional screening indicator (asi) to the MS as follows: - Presentation Indicator: a) Presentation allowed; b) Presentation restricted
26、; c) Number not available. - Screening indicator/additional Screening indicator: a) b) User provided, not screened; c) network provided. User provided, verified and passed; The screening indicator or additional screening indicator applies to the ISDN/MSISDN or the number given as additional line ide
27、ntity respectively. 0.2.2 Abbreviations Abbreviations used in this specification are listed in GSM 01.04.
