The procedure CAMEL_Provide_Subscriber_Info is called either during Retrieval of routeing information in the HLR or as a result of reception of the Any Time Interrogation information flow from the gsmSCF.
The HLR sends a Provide Subscriber Info information flow to the VLR or SGSN dependent on the setting of the parameter "requested domain" received from the calling process.
If the VLR or SGSN returns a Provide Subscriber Info ack information flow, then the HLR uses the received information to set the Subscriber Info to be returned to the calling process.
As a network option, the HLR may use the information received from the VLR, such as Cell Id, Location Area Id or Service Area Id, to derive the Location Number and/or Geographical Information. The HLR may use the information received from the SGSN, such as Cell Id, Location Area Id, Service Area Id or Routeing Area Identity, to derive the Location Number and/or Geographical Information. This mapping is network-specific and outside the scope of the present document.
NOTE: The handling in the VLR of Provide Subscriber Info is defined in 3GPP TS 23.018 . The handling in the SGSN of Provide Subscriber Info is defined in clause 11.
