METHOD AND APPARATUS FOR ACCESSING A PLURALITY OF COMMUNICATION NETWORKS |
摘要 |
A method enables a subscriber unit (20) to access a common communication system to communicate with a selected communication system. The subscriber unit receives (404) an indication of any communication systems available in a geographic region associated with the common communication system and requests access to the selected communication system. After receiving (506) an enabling program for the selected communication system, the subscriber unit transfers (508) the enabling program to an external processing device. A novel subscriber unit (20) and external processing device (24) are also described.
