24、y is made up of the following information units: - The subscribers international ISDNMSISDN number; - 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 us
25、er equipment). 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 additional calling line identity provides additional line information for the purpose of the calling line identification presentation servi
26、ce (CLIP). The additional connected line identity provides additional line information for the purpose of the connected line identification presentation service (COLP).

27、) For mobile originating calls the user (or user equipment) has no possibility to provide an additional line identity. For mobile terminating calls the user (or user equipment) has no possibility to provide an additional connected line identity. 0.2.1.2 Definition of presentation and screening indic
28、ators In 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 re
29、stricted; c) Number not available. - Screening indicatorhdditional Screening indicator: a) User provided, verified and passed; b) User provided, not screened; c) network provided. The screening indicator or additional screening indicator applies to the ISDN/MSISDN or the number given as additional l

The HLR shall also store the subscription option “override category“ on a per subscriber basis. This parameter takes one of the
48、following values: - yes; - no. 1.4 State transition model The following figure shows the successful cases of transition between the applicable logical states of CLIP. The state changes are caused by actions of the service provider. Note that error cases are not shown in the diagram as they normally
49、do not cause a state change. Additionally, some successful requests may not cause a state change. Hence they are not shown in the diagram.
