Patent ID: 8280848

Claim:
A method of synchronizing network data for automatically updating the data of external network operators with roaming or routing data, between at least a first database connected to a first data-processing system associated with a first communication network and a second database connected to a second data-processing system associated with a second communication network and connected to the first data-processing system by a communication link, the method comprising the steps of: storing in the first database network data held in data record sets and suitable for synchronization with the second database, providing each of the first and second data-processing systems with a respective program operating as respective first and second agents independently and autonomously to control data access and data storage in the respective databases to carry out an internal synchronization of the respective databases with up-to-date network data, providing the first agent with a first interface for accessing data in the first database and a second interface to an external network operator for sending data to this external operator; maintaining a logbook on the first data-processing system in which changes relating to the content of the first database are entered, and depending on a logbook entry transmitting data reflecting a change of at least one data record set from the first data-processing system to the second data-processing system by the first agent first checking the logbook as to which data in the first database has changed since the last forwarding to the external network operator, accessing the data in the first database via the first interface by the first agent, forwarding the accessed data by the first agent via the second interface through the communication link to the second data-processing system, receiving the forwarded data by the second agent, and storing the received data by the second agent in the second database.
