携帯型装置に関する「ネットワーク内発呼者」情報の表示を強化するためのシステムおよび方法

摘要

System and method for determining reporting to a subscriber whether an incoming call originates from inside or outside of a mobile carrier's network. An example system performs a GTT (global title translation) on an incoming number to determine the hosting carrier of any mobile phone number. When the result matches the subscriber's carrier, the mobile device then indicates to the subscriber (i.e. mobile device) that the call is an“in network call.”
