Reply To: USSD call from roaming subs

Wallis Dudhnath


This method() is used between the MSC and the VLR and between the VLR and the HLR to relay information in order to allow unstructured supplementary service operation. It should contain the MSISDN. The VPLMN’s VLR should add the MSISDN into the MAP message.

The HLR will interact with a USSD-Gateway.
