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 plurality of databases in a wireless communication system having a plurality of wireless communication devices, the method comprising:

establishing a first database group comprising at least a subset of the plurality of wireless communication devices to manage a first database of the plurality of databases, wherein each wireless communication device of the first database group is configurable to be a master device or a slave device;

configuring a first device of the first database group to be a master wireless communication device, and the other devices of the first database group to be a plurality of slave wireless communication devices;

assigning a priority level to each slave wireless communication device;

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

retransmitting the database modification request message by the initiating slave wireless communication device if an acknowledgement message is not received from the master wireless communication device within a maximum time period in accordance with a collision avoidance procedure, wherein the maximum time period is based upon the priority level assigned to the initiating slave wireless communication device.

2. The method of claim 1, further comprising:

transmitting a database modification instruction message to the plurality of non-initiating slave wireless communication devices.

3. The method of claim 1, wherein the collision avoidance procedure comprises:

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

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

4. A method of database management in a wireless communication system, comprising a master-slave configuration, the method comprising:

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

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

retransmitting the database modification request message from the initiating slave wireless communication device if an acknowledgement message is not received from the master wireless communication device within a maximum time period, wherein the maximum time period is based upon a priority level assigned to the initiating slave wireless communication device.

5. The method of claim 4, 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.

6. A wireless communication device, within in a wireless communication system with a master-slave configuration, 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;

a transceiver configured to transmit the database modification request message, through a base station, to a master wireless communication device maintaining a second data version of a database 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;

the transceiver is further configured to receive an acknowledgement message from the master wireless communication device; and

the transceiver is further configured in accordance to a collision procedure to retransmit the database modification request message if the acknowledgement message is not received from the master wireless communication device within a maximum time period, wherein the maximum time period is based upon a priority level assigned to the wireless communication device.

7. The wireless communication device of claim 6, wherein the transceiver is further configured to receive, from the master wireless communication device through a base station, a database modification instruction message including a requested database modification submitted by an initiating slave wireless communication device, 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.

8. The wireless communication device of claim 6, 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.
