Abstract
The present invention discloses a method for tracking location of synchronous and asynchronous mobile communication network subscribers by using a dual stack home location register and a dual stack mobile positioning center. When the dual stack mobile positioning center externally receives a location tracking request for a subscriber, it requests reception subscriber information to the dual stack home location register, confirms whether the terminal is located in a synchronous or asynchronous mobile communication network by referring to the reception subscriber information from the dual stack home location register and network information, and requests location tracking for the terminal to the corresponding mobile communication network. Accordingly, location of the synchronous and asynchronous mobile communication network subscribers can be tracked in the network in which mobile communication networks using different protocols coexist.
