CAMEL subscribers have one or more CAMEL Subscription Information (CSI) elements.

  • CAMEL Subscription Information is provided by the HPLMN operator by administrative means.
  • The following CSIs may be administered per subscriber:
D-CSI
  • Dialled Services CAMEL Subscription Information (D-CSI) is transferred to the VPLMN (at location update), IPLMN (for an incoming call in GMSC) or the IM CN subsystem. D-CSI contains trigger information which is required to invoke a CAMEL service logic for subscribers dialled services.

GPRS-CSI

  • GPRS CAMEL Subscription Information (GPRS-CSI) is transferred to the VPLMN. GPRS-CSI contains trigger information which is required to invoke a CAMEL Service Logic for GPRS Sessions and PDP Contexts.

M-CSI

  • Mobility Management CAMEL Subscription Information (M-CSI) is transferred to the VPLMN. M-CSI is used to notify the CSE about Mobility Management events for the CS subscriber.

MG-CSI

  • Mobility Management for GPRS CAMEL Subscription Information (MG-CSI) is transferred to the VPLMN. MG-CSI is used to notify the CSE about Mobility Management events for the GPRS subscriber.

SMS-CSI

  • Originating Short Message Service CAMEL Subscription Information (MO-SMS-CSI) is transferred to the VPLMN. MO-SMS-CSI contains trigger information that is required to invoke a CAMEL Service Logic for Mobile Originating Short Message submissions.

MT-SMS-CSI

  • Terminating Short Message Service CAMEL Subscription Information (MT-SMS-CSI) is transferred to the VPLMN. MT-SMS-CSI contains trigger information that is required to invoke a CAMEL Service Logic for Mobile Terminating Short Message delivery.

O-CSI

  • Originating CAMEL Subscription Information (O-CSI) is transferred to the VPLMN (at location update),to the IPLMN (for an incoming call in the GMSC) and to the IM CN subsystem. O-CSI contains trigger information that is required to invoke a CAMEL Service Logic for Mobile Originating calls (in the VMSC) and Mobile Forwarding calls (in the VMSC and the GMSC).

SS-CSI

  • Supplementary Service Invocation Notification CAMEL Subscription Information (SS-CSI) is transferred to the VPLMN. SS-CSI is used to notify the CSE about the invocation of certain Supplementary Services.

T-CSI

  • Terminating CAMEL Subscription Information (T-CSI) is transferred to the IPLMN for an incoming call in the GMSC. T-CSI contains trigger information which is required to invoke a CAMEL Service Logic for Mobile Terminating calls in the GMSC.

TIF-CSI

  • Translation information Flag CAMEL Subscription Information (TIF-CSI) is transferred to the VPLMN. TIF-CSI is used in the HLR for registering short Forwarded-to-Numbers (FTNs). When TIF-CSI is present, the subscriber is allowed to register short FTNs.
    When the subscriber invokes Call Deflection, TIF-CSI in the VPLMN allows the subscriber to deflect to short Deflected-to-Numbers.

U-CSI

  • USSD CAMEL Subscription Information (U-CSI) is held in the HLR; it is not sent to any other node. U-CSI contains trigger information which is used to invoke a USSD application in the CSE for the served subscriber.

UG-CSI

  • USSD General CAMEL Subscription Information (UG-CSI) is held in the HLR; it is not sent to any other node. UG-CSI contains trigger information which is used to invoke a USSD application in the CSE for all subscribers.

VT-CSI

  • VMSC Terminating CAMEL Subscription Information (VT-CSI) is transferred to the VPLMN at location update and to the IM CN subsystem. VT-CSI contains trigger information which is required to invoke a CAMEL Service Logic for Mobile Terminating calls in the VMSC.
  • Refer to 3GPP TS 23.078 for detailed descriptions of the various types of CAMEL Subscription Information.
  • The CSI may include the Default Call Handling, Default GPRS Handling or Default SMS Handling.
  • The Default Call Handling indicates whether the call shall be released or continued if the contact with the CSE is not confirmed or is interrupted.
  • Network -based services may be provided by the serving PLMN operator. The provisioning mechanism is out of the scope of this specification.
  • Trunk originated services may be provided by the PLMN operator. The provisioning mechanism is out of the scope of this specification.

MO-SMS-CSI (Mobile Originating Short Message Service CAMEL Subscription Information)

  • is transferred to the VPLMN. MO-SMS-CSI contains trigger information that is required to invoke a CAMEL Service Logic for Mobile Originating Short Message submissions.

MT‑SMS‑CSI (Mobile Terminating Short Message Service CAMEL Subscription Information):

  • MT‑SMS‑CSI identifies the subscriber as having MT SMS CAMEL services.

GPRS CAMEL Subscription Information (GPRS‑CSI):

  • GPRS‑CSI identifies the subscriber as having GPRS CAMEL services.
