Abstract

In a wireless communication system (10) including a transmission source (21), a wireless subscriber unit (26) contains a function key (52) for performing an operation on a function value (50). In response to receiving a change notification message (28), the transmission source (21) sends a message (38) to the wireless subscriber unit (26). The function value (50) is changed based on receipt of the message (38) sent from the transmission source (21).

Claims

1. In a wireless communication system in which a wireless subscriber unit has a receiver for receiving a message sent from a transmission source and a function key which operates using a function value, the transmission source including a receiver for receiving a change notification message, a method for updating the function value, comprising:

operating the function key using a first function value;

communicating the change notification message to the transmission source, and the transmission source responding thereto by sending a message to the wireless subscriber unit;

the wireless subscriber unit substituting a second function value for the first function value; and

operating the function key using the second function value.

2. A method as recited in claim 1, wherein:

the transmission source notifies the wireless subscriber unit of the second function value.

3. A method as recited in claim 1, wherein:

the second function value is sent as a message from the transmission source to the wireless subscriber unit.

4. A method as recited in claim 1, wherein:

the second function value is sent from the transmission source to the wireless subscriber unit as an attachment to a message.

5. A method as recited in claim 1, wherein the wireless subscriber unit has a geographic location, and wherein the change notification message is communicated in response to a change in a geographic location of the wireless subscriber unit.

6. In a wireless subscriber unit having a receiver for receiving a message sent from a transmission source, a transmitter for sending a change notification message to the transmission source, and a function key which operates using a function value, a method for updating the function value, comprising:

operating the function key using a first function value;

sending the change notification message to the transmission source;

substituting a second function value for the first function value in response to receiving a message; and

operating the function key using the second function value.

7. A method as recited in claim 6, wherein:

the wireless subscriber unit receives notification of the second function value.

8. A method as recited in claim 7, wherein:

the wireless subscriber unit receives the second function value as a message.

9. A method as recited in claim 7, wherein:

the wireless subscriber unit receives the second value function as an attachment to a message.

10. A method as recited in claim 6, wherein the wireless subscriber unit has a geographic location, and wherein the change notification message is sent in response to a change in a geographic location of the wireless subscriber unit.
