Abstract

An apparatus, system, and method provide database management within a wireless communication system by maintaining a database within wireless communication devices transmitting changes using wireless messages. An initiating slave wireless communication device, maintaining a first data version of a database, transmits a database modification request message to a master wireless communication device maintaining a second data version of the database. After modifying the second data version of the database in accordance with the database modification request message, the master wireless communication device transmits a database modification instruction to any number of non-initiating slave wireless communication devices to modify other data versions of the database maintained at the respective non-initiating slave wireless device. As a result, the multiple data versions are synchronized to maintain a database within the wireless communication system.

Claims

1. A method of managing a database in a wireless communication system, the method comprising:

receiving, at a master wireless communication device through a wireless communication channel, a database modification request message generated by an initiating slave wireless communication device maintaining a first data version of a database;

modifying a second data version of the database stored in the master wireless communication device in accordance with the database modification request message.

2. The method of claim 1, further comprising:

transmitting a database modification instruction message to a non-initiating slave wireless communication device.

3. The method of claim 2, wherein the database modification request message has a format in accordance with a format selected from the group consisting of a Short Message Services (SMS) format, an Instant Messaging (IM) format, an Enhanced Messaging Services (EMS) format, and a Multimedia Messaging Services (MMS) format.

4. The method of claim 2, further comprising:

receiving, at the master wireless communication device, another database modification request message generated by another initiating slave wireless communication device maintaining a third data version of a database, wherein the modifying the second data version comprises modifying the second data version in accordance with a collision avoidance procedure.

5. The method of claim 4, wherein the collision avoidance procedure comprises:

modifying the second data version in accordance with a first received database modification message; and

transmitting an acknowledgment message to the initiating slave wireless communication device transmitting the first received database modification message.

6. A method of database management in a wireless communication system, the method comprising:

maintaining, in an initiating slave wireless communication device, a first data version of a database; and

transmitting to a master wireless communication device through a wireless communication channel, a database modification request message to modify the database in accordance with a requested database change entered by a user at the initiating slave wireless communication device.

7. The method of claim 6, wherein the database modification request message has a format in accordance with a format selected from the group consisting of a Short Message Services (SMS) format, an Instant Messaging (IM) format, an Enhanced Messaging Services (EMS) format, and a Multimedia Messaging Services (MMS) format.

8. The method of claim 6, further comprising:

receiving an acknowledgement message from the master wireless communication device; and

applying the requested database change to the first data version of the database.

9. A wireless communication device comprising:

a transceiver configured to receive a database modification request message generated by an initiating slave wireless communication device maintaining a first data version of a database;

a memory configured to store a second data version of the database; and

a controller configured to modify the second data version in accordance with the database modification request message.

10. The wireless communication device of claim 9, wherein the database modification request message has a format in accordance with a format selected from the group consisting of a Short Message Services (SMS) format, an Instant Messaging (IM) format, an Enhanced Messaging Services (EMS) format, and a Multimedia Messaging Services (MMS) format.

11. The wireless communication device of claim 9, wherein the transceiver is further configured to transmit a database modification instruction message to a non-initiating slave wireless communication device.

12. The wireless communication device of claim 11, wherein the database modification instruction message has a format in accordance with a format selected from the group consisting of a Short Message Services (SMS) format, an Instant Messaging (IM) format, an Enhanced Messaging Services (EMS) format, and a Multimedia Messaging Services (MMS) format.

13. The wireless communication device of claim 9, wherein the transceiver is further configured to transmit an acknowledgement message to the initiating slave wireless communication device.

14. The wireless communication device of claim 13, wherein the acknowledgement message is a positive acknowledgement message when the database modification request message is a first received message from a plurality of database modification request messages and wherein the acknowledgement message is a negative acknowledgement message, otherwise.

15. A wireless communication device comprising:

a memory configured to store a first data version of a database;

a controller configured to generate a database modification request message in accordance with a user input; and

a transceiver configured to transmit the database modification request message to a master wireless communication device maintaining a second data version of a database.

16. The wireless communication device of claim 15, wherein the database modification request message has a format in accordance with a format selected from the group consisting of a Short Message Services (SMS) format, an Instant Messaging (IM) format, an Enhanced Messaging Services (EMS) format, and a Multimedia Messaging Services (MMS) format.

17. The wireless communication device of claim 15, wherein the transceiver is further configured to receive, from the master wireless communication device, a database modification instruction message including a requested database modification submitted by an initiating slave wireless communication device.

18. The wireless communication device of claim 17, wherein the database modification instruction message has a format in accordance with a format selected from the group consisting of a Short Message Services (SMS) format, an Instant Messaging (IM) format, an Enhanced Messaging Services (EMS) format, and a Multimedia Messaging Services (MMS) format.

19. The wireless communication device of claim 15, wherein the transceiver is further configured to receive an acknowledgement message from the master wireless communication device.

20. The wireless communication device of claim 19, the controller further configured to, in response to a positive acknowledgement message, to apply a user entered database modification corresponding to the database modification request message to the first data version.
