CELLULLAR PHONE WITH PHONEBOOK

FOR INTERNATIONAL DIALLING~

by Rainer Frank

ABSTRACT

  Country codes and international access codes are stored in a cellular telephone. This enables users to make calls to foreign countries without knowing these codes.

INTRODUCTION

  This application simplifies the dialling proce- dure when using cellular phones between different countries.

PROBLEM TO BE SOLVED

  The use of cellular phones between different countries always requires an international access code (which is 00 in most European countries and 011 in the US) and a country code. Very often only the country code of a user's own country is well known to the user, but others are not. A phone book is required to get this information. The phone book is not always at hand when needed.

  Most cellular phones provide features which allow the storage of phone numbers, either in the phone or on the smartcard. This tends to be for local use only. The country code is not included and the phone number which is stored includes the zero at the beginning of the city-or area code. This zero must be left out when dialling from another country.

PROPOSED SOLUTlOti TO THE PROBLEM

  The proposed solution is to add an additional field in the internal phonebook which contains a country identifier. When dialling to another country the user has to select otdy the entry in the phone- book as he does locally. The phone knows the coun- try into whose telephone network it is currently logged in. The database uses this information to add the required internationals access code and the coun- try code automatically.

  With this arrangement, the existing personal phone book can be used to dial to and from foreign countries in the same way as it is used within one country. The benefit for the user is that (s)he does not need to know all the additional codes that are required to call to another country.
