ABSTRACT:
A method for synchronizing multiple database that are provided at different times is provided. As a wireless communication device (102) leaves a first region (104) and enters a second region (108), it is provided with a new preferred roaming list information (204) which may no longer be synchronized with a stored functionality extension table. Based upon information included in the new preferred roaming list information, an appropriate functionality extension table (214) that is synchronized to the new preferred roaming list is received.
