Abstract

Roaming enables a mobile phone in a cellular phone system to receive or to make long distance calls. Such calls are typically more expensive than local calls and therefore most subscribers prefer to minimize long distance calls in order to reduce phone bills. It is therefore desirable for a subscriber to know whether a communication call is long dis- tance or local before starting voice communications.

DISPLAYING LOCATION OF AN OPPOSITE PARTY BEFORE

STARTING VOICE COMMUNICATIONS

by TY Sea and TH Kuek

  Roaming enables a mobile phone in a cellular phone system to receive or to make long distance calls. Such calls are typically more expensive than local calls and therefore most subscribers prefer to minimize long distance calls in order to reduce phone bills. It is therefore desirable for a subscriber to know whether a communication call is long dis- tance or local before starting voice communications.

  This article describes a feature for a mobile phone to display the location of an opposite party before starting voice communications.

THEORY OF OPERATION

  Software at a Mobile Switching Center (MSC) is modified to send to the mobile phone of either a calling or a receiving party the location code of an opposite party. Accordingly, the software in a mobile phone analyzes this location code and dis- plays it as country/state on a display screen. Location codes associated with country/state infor- mation are stored in a memory within the mobile phone. These location codes are used to determine the location of either the calling party or the receiv- ing party. Two operational flowcharts of how this feature is implemented in respective mobile phones of a calling party and a receiving party are shown on the following pages.
