Abstract

An apparatus adapted to operate as an A party in a database synchronization with a B party via a mobile communication network. The database contains data items to be synchronized. The apparatus includes mechanisms for maintaining a copy of the database and a client-server communication module with a client part and a server part. The client part is configured to communicate via the mobile communication network with the server part of the B party. The apparatus also includes change detection mechanisms responsive to a detection of a changed data item, for initiating a synchronization event via the client part of the client-server communication module.

First claim

What is claimed is:

1. Within a system comprising an Internet Protocol (IP) network coupled between a first computer and a second computer, a method comprising:
establishing and maintaining a data path over the IP network between the first computer and the second computer using a tunnelling protocol;
maintaining a first database on the first computer, the first database having an existing data item;
maintaining a second database on the second computer, the second database having a corresponding data item that has been previously synchronized with the existing data item;
detecting a change in the existing data item by the first computer; and
transmitting a notification message from the first computer to the second computer over the data path, the notification message comprising:
an indication the existing data item has changed; and
the change in the existing data item;
and
updating the corresponding data item, wherein detecting the change, verifying the data path, and transmitting the notification message are executed in near real-time.

2. The method of claim 1 , wherein the system is implemented within a mobile communication network.

3. The method of claim 2 , wherein the first computer comprises a server.

4. The method of claim 3 , wherein the second computer comprises a server.

5. The method of claim 4 , wherein the IP network is an intranet.

6. The method of claim 1 , further comprising verifying the data path.

7. The method of claim 1 , wherein the tunneling protocol is a GPRS Tunnelling Protocol (GTP).

8. A system comprising:
a first computer having a first database, the first database having an existing data item;
a second computer having a second database, the second database having a corresponding data item that has been previously synchronized with the existing data item; and
an Internet Protocol (IP) network coupled between the first computer and the second computer; wherein:
the first computer is configured to:
establish and maintain a data path over the IP network between the first computer and the second computer using a tunnelling protocol;
maintain the first database;
detect a change in the existing data item;
and
transmit a notification message to the second computer over the data path, the notification message comprising:
an indication the existing data item has changed; and
the change in the existing data item, wherein the first computer is further configured to detect the change, verify the data path, and transmit the notification message in near real-time;

and
the second computer is configured to:
receive the notification message; and
update the corresponding data item.

9. The system of claim 8 , wherein the system is implemented within a mobile communication network.

10. The system of claim 9 , wherein the first computer comprises a server.

11. The system of claim 10 , wherein the second computer comprises a server.

12. The system of claim 11 , wherein the IP network is an intranet.

13. The system of claim 8 , wherein the first computer is further configured to verify the data path.

14. The system of claim 8 , wherein the tunneling protocol is a GPRS Tunnelling Protocol (GTP).
