Method for associating one directory number with two mobile stations within a mobile telecommunications network

摘要

A home location register (HLR) associated with a particular mobile subscription correlates two different international mobile subscriber identity (IMSI) numbers with a particular mobile subscriber integrated service digital network (MSISDN) number. When an incoming call connection is received towards that MSISDN number, the HLR makes a determination as to which one of the two mobile stations associated with the two IMSI numbers is active. The incoming call connection is then forwarded to the active mobile station. In case both mobile stations are active, the received incoming call connection is rerouted to the mobile station preassigned as a primary mobile station.
