6 Description of CAMEL Subscriber Data

03.783GPPCcustomized Applications for Mobile network Enhanced Logic (CAMEL) Phase 2Release 1998Stage 2TS

6.1 Originating/Terminating CAMEL Subscription Information (O/T-CSI)

This subclause defines the contents of the Originating/Terminating CAMEL Subscription Information.

6.1.1 gsmSCF address

Address to be used to access the gsmSCF for a particular subscriber. The address shall be an E.164 number to be used for routeing.

6.1.2 Service Key

The Service Key identifies to the gsmSCF the service logic that should apply.

6.1.3 Default Call Handling

The Default Call Handling indicates whether the call shall be released or continued as requested in case of error in the gsmSSF to gsmSCF dialogue.

6.1.4 TDP List

The TDP List indicates on which detection point triggering shall take place. For O-CSI only DP2 is used. For T-CSI only DP12 is used.

6.1.5 DP criteria

The DP criteria indicate whether the gsmSSF shall request the gsmSCF for instructions.

6.1.6 CAMEL Capability Handling

CAMEL Capability Handling indicates the phase of CAMEL which is asked by the gsmSCF for the service. The HLR shall not include in a CSI which it sends to a VLR or GMSC any data for a CAMEL phase later than that which the CAMEL capability handling indicates. E.g. if the CAMEL Capability Handling indicates CAMEL phase 1 then the HLR shall not send triggering criteria to the VLR. Different CSIs may contain different values of CAMEL Capability Handling.

NOTE: If CAMEL is not supported or if a lower phase of CAMEL is supported in the VLR, the HLR can decide on a subscriber basis to apply ODB, perform normal call handling or perform operator specific handling (eventually support of a lower version of CSI).

6.2 Other CAMEL data

6.2.1 USSD CAMEL Subscription Information (U‑CSI)

The subscription information specified in this subclause is for information only.

This subclause defines the contents of the USSD CAMEL Subscription Information (U-CSI). The U-CSI consists of a list of pairs of the following two parameters.

6.2.1.1 Service Code

Service code for a specific application in a gsmSCF which interacts with the user by USSD.

6.2.1.2 gsmSCF address

Address to be used to access the gsmSCF for a particular subscriber and a particular service code. The address shall be an E.164 number to be used for routeing.

6.2.2 Supplementary Service Invocation Notification CAMEL Subscription Information (SS-CSI)

6.2.2.1 Content of the SS-CSI

This subclause defines the contents of the Supplementary Service Invocation Notification CAMEL Subscription Information (SS-CSI).

6.2.2.1.1 Notification criteria

This data indicates for which supplementary services notifications shall be sent. The supplementary services which may be indicated are ECT, CD and MPTY.

6.2.2.1.2 gsmSCF address

Address to be used to access the gsmSCF for a particular subscriber. The address shall be an E.164 number to be used for routeing.

6.2.3 Location information/Subscriber state Interrogation

This data indicates whether additional subscriber information shall be sent to the GMSC as part of the terminating call handling.

– An indication that the HLR shall send the location information of the called subscriber.

– An indication that the HLR shall send the subscriber state of the called subscriber.

6.2.4 Translation Information Flag (TIF-CSI)

A flag (TIF-CSI) in the CAMEL Subscriber data in the HLR indicates, when the subscriber registers a forwarded-to number, that the HLR shall not attempt to perform any translation, number format checks, prohibited FTN checks, call barring checks (cf. 10.2).

If the flag is absent, this indicates that a translation is needed in the HLR and the usual procedure applies as defined in the current version of TS 3GPP TS 03.82 [13]. In particular, the interaction with barring services shall be performed by the HLR at the registration of the FTN.
