METHOD TO RESTORE SUBSCRIBER RELATED INFORMATION IN A COMMUNICATION NETWORK DATA BASE SYSTEM

摘要

In order to restore subscriber related information in a first data base system of a first communication network for subscribers who are logged into both a first and a second communication network, a second data base system is provided in a communication network to store subscriber data records, along with a control device to store subscriber related information from subscriber data records from several wireless communication systems in a storage device. The control device is also used to forward subscriber related information requested from the first data base system to the first communication network.
