[edit] Usage

This operation is sent by the gsmSSF after detection of a request in the BCSM, to request the gsmSCF for instructions to complete a call.

[edit] Expected actions

• A control relationship is established between the gsmSSF and the gsmSCF. The gsmSSF awaits for instructions from gsmSCF.

[edit] Invoke parameters

• serviceKey – identifies the requested IN service within the gsmSCF.

• calledPartyNumber – the number that indentifies the called party in the forward direction. Parameter is sent only in the Mobile Terminating/Forwarding cases.

• callingPartyNumber – the calling party / origin of the call.

• callingPartysCategory – type of calling party.

• iPSSPCapabilities – indicates which gsmSRF resources are supported within the VMSC/GMSC the gsmSSF resides in.

• locationNumber – the geographical area address for mobility services, used when the “callingPartyNumber” does not contain the geographical location of the calling party.

• originalCalledPartyID – the dialed digits if the call was forwarded at some point on the route to the gsmSSF.

• extensions

• highLayerCompatibility – identifies de ISDN-teleservice of a connected terminal.

• additionalCallingPartyNumber – number provided by the access signalling system of the calling user.

• bearerCapability – the type of connection to the user. Contains the following parameter:
  • bearerCap – value of the ISUP USI parameter.

The parameter should only be included if ISUP USI parameter is available at gsmSSF. If ISUP USI (User Service Information) and USI Prime are both available at gsmSSF, “the bearerCap” shall contain USI Prime parameter.

• eventTypeBCSM – the event which triggerred the InitialDP operation.

• redirectingPartyID – the number from which the call was redirected.

• redirectionInformation – redirection information, such as redirect counter.

• imsi - IMSI of the mobile subscriber for which the CAMEL service is invoked

• subscriberState - the state of the mobile subscriber for which the CAMEL service is invoked, possible states are Busy, Idle, Not reachable and Not provided from VLR.

• locationInformation – provides the location of the MS and the age of its whereabouts

• ext-basicServiceCode - indicates the Basic Service Code

• callReferenceNumber - call reference number assigned to the call by the GMSC/MSC

• mscAddress - gives the mscId assigned to the GMSC/MSC.

• calledPartyBCDNumber – number used to identify the called party. Sent only in MO case.

• timeAndTimezone – the time when the gsmSSF was triggered, including the timezone

• gsm-ForwardingPending – indicates that a call is to be forwarded due to a forwarded-to-number being received

• initialDPArgExtension - contains the following 2 parameters:
  • naCarrierInformation - the carrier identification code and carrier selection type associated with the calling subscriber of a mobile originating call / the called subscriber of a mobile terminating call / the forwarding subscriber of a mobile forwarded call.
  • gmscAddress – gives the mscId assigned to the GMSC
