METHOD AND SYSTEM FOR PROVIDING COMMUNICATION SERVICES TO A ROAMING WIRELESS DEVICE

摘要

Method and system for optimizing the roaming mechanism through handling by the visited network the data that are sent by the wireless devices without routing these data to the home network. International gateways are therefore not used or are used for much fewer communications, thereby decreasing the cost of roaming for telecommunication operators. In addition, the invention allows processing in the home network the authentication and charging operation that needs sensitive information, preserving thereby the security of data.
