Abstract

A wireless message communication system (11) delivers dynamically configurable datagram messages between a server (15) and subscriber units (17, 18, 19, 20, 21, 22). The server (15) queries a subscriber unit (17) for its data capability profile, such as supported data types, number of data fields, size of each data field, and data type for each data field. The server (15) and the subscriber unit (17) dynamically configure a message datagram (200) to conform message information in transmitted data to the data capability profile of the subscriber unit (17). The server (15) and the subscriber unit (17) then wirelessly communicate a message containing message data packets arranged and formatted according to the message datagram (200).

Claims

1. A wireless communication system for minimizing the data sent between a central server and a subscriber unit, comprising:

a central server for communicating message data with subscriber units according to a dynamically configurable datagram;

a wireless transceiver, communicatively coupled to the central server, for receiving message data from the server and wirelessly transmitting said message data into a communication channel destined for reception by a subscriber unit, and for wireless reception of message data transmitted from a subscriber unit and destined for reception by the central server and thereby forwarding the wirelessly received message data to the central server;

a subscriber unit for communicating message data with the server according to a dynamically configurable datagram, the central server being responsive to a wirelessly transmitted message from the subscriber unit to dynamically configure the dynamically configurable datagram according to a data capability profile of the subscriber unit and thereby customizing a communication of message data between the subscriber unit and the central server according to the data capability of the subscriber unit;

wherein the dynamically configurable datagram is configured to wirelessly communicate message data containing administrative changes for the subscriber unit, and wherein the administrative changes include personalizing the subscriber unit, and wherein the administrative changes include diagnosis of said subscriber unit.

2. The wireless communication system of claim 1 wherein the data capability profile of the subscriber unit indicates at least one of the supported data types at the subscriber unit, the number of data fields for storing in memory at the subscriber unit, the size of each data field for storing in the memory at the subscriber unit, and the data type for each data field.

3. The wireless communication system of claim 1, wherein the dynamically configurable datagram is dynamically configured for wireless transmission of message data from the central server to the subscriber unit.

4. The wireless communication system of claim 1, wherein the dynamically configurable datagram is dynamically configured for wireless transmission of message data from the subscriber unit to the central server.

5. The wireless communication system of claim 1, wherein the dynamically configurable datagram is dynamically configured for transmitting substantially only the message data relevant to the subscriber unit.

6. The wireless communication system of claim 1, wherein the data capability profile indicates a maximum number of data fields for a subscriber unit memory.

7. The wireless communication system of claim 1, wherein the data capability profile indicates a maximum data size for a data field for a subscriber unit.

8. The wireless communication system of claim 1, wherein the data capability profile indicates a memory storage configuration for the subscriber unit.

9. The wireless communication system of claim 1, wherein the dynamically configurable datagram identifies a data protocol type for wireless communication of message data.

10. The system of claim 1, wherein the administrative changes include changing a data transmission protocol for the subscriber unit.
