Thanks for clarification Roameo & Scot.
In a scenario, where a subscriber is in the VPLMN, can the VPLMN network alot a local IMSI-MSISDN and map it to the original(HPLMN) IMSI-MSISDN so that all calls towards & from original IMSI can be treated as calls to/from local IMSI-MSISDN pair?
This is like a multi imsi scenario just that the simcard is not a multi imsi simcard, its the original single imsi sim, just that the mapping between 2 IMSIs is maintained in the MSC(of the VPLMN) in which the subscriber is. This should be done without involving the HPLMN.
Any thoughts?
