RestoreData

Usage

This message is sent by a VLR to a HLR if it does not have subscriber data for an IMSI or has reasons to believe the data is unreliable (after an outage).

Expected actions

• The HLR must Invoke an insertSubscriberData request to the VLR to let it know about the settings and available services of the subscriber. This should be done in the same transaction and wait for the completion.

• The HLR must ResultLast to the restoreData including its own hlr-Number

Invoke parameters

• imsi – IMSI of the SIM card
• lmsi – Local mobile station identity (VLR specific)
• extensionContainer – Container for various extensions
• vlr-Capability – Capabilities of the VLR
  • supportedCamelPhases – Supported CAMEL phases, can be "phase1" and/or "phase2"
  • extensionContainer – Container for various extensions
  • solsaSupportIndicator – If present indicates Support Of Location Service Area

Result parameters

• hlr-Number – HLR identification string / number
• msNotReachable – If present indicate the Mobile Station is known unreachable
• extensionContainer – Container for various extensions
