Abstract

A method and apparatus for indicating message status in a wireless communication system comprising a base station configured to communicate with at least one mobile unit over a wireless interface. The mobile unit includes an indicator having first and second human perceptible states, with the first state indicating a lack of message waiting condition, and the second state indicating a message waiting condition. The base station monitors communications from a messaging system. When a communication is received indicating message status or a change in message status, the base station transmits a command regarding message status to the mobile unit over the wireless interface. In response, the mobile unit maintains or changes the state of the indicator to reflect the message status as determined by the command.

Claims

1. A message notification unit configured to communicate control information over a wireless interface to a base station, the base station configured to communicate with a messaging system regarding a message status for the message notification unit, the message notification unit comprising:

an indicator having first and second human perceptible states to indicate the message status, the first state for indicating a no message waiting condition, and the second state for indicating a message waiting condition;

a receiver configured to receive, over the wireless interface, a message signal from the base station containing information regarding the message status;

a controller configured to maintain or change the state of the indicator to reflect the message status based on the message signal; and

a transmitter configured to transmit a range signal to the base station periodically;

wherein receipt of the range signal by the base station is an indication to the base station that the message notification unit is within a proper range to receive the message signal from the base station.

2. The message notification unit of claim 1, wherein the message notification unit has a message notification unit address, and wherein the message signal includes a message signal address.

3. The message notification unit of claim 1, wherein the base station is in communication with the message system via a telephone line, and wherein the message status indicates the message waiting condition if the base station receives a stuttering dial tone or a VMWI FSK signal.

4. A message notification method for use by a message notification unit configured to communicate with a base station over a wireless interface, the base station configured to communicate with a messaging system regarding a message status for the message notification unit, the message notification method comprising:

transmitting a range signal to the base station periodically, wherein receipt of the range signal by the base station is an indication to the base station that the message notification unit is within a proper range to receive a message signal from the base station;

receiving, over the wireless interface, the message signal from a base station containing information regarding the message status; and

indicating a no message waiting condition and a message waiting condition based on the message signal in human perceptible states to indicate the message status.

5. The message notification method of claim 4, wherein the message notification unit has a message notification unit address, and wherein the message signal includes a message signal address.

6. The message notification method of claim 4, wherein the base station is in communication with the message system via a telephone line, and wherein the message status indicates the message waiting condition if the base station receives a stuttering dial tone or a VMWI FSK signal.

7. A mobile station configured to receive a message waiting notification from a base station, the base station being in communication with a messaging system over a communication line, the base station including a message waiting detector, wherein the message waiting detector indicates a message waiting if the message waiting detector detects either a stuttering dial tone over the communication line or a VMWI FSK signal, the mobile station comprising:

an indicator having first and second human perceptible states, the first state for indicating a no message waiting condition and the second state for indicating a message waiting condition;

a receiver configured to receive, over the wireless interface, a message signal from the base station, the message signal indicative of one of the no message waiting condition and the message waiting condition;

a controller configured to maintain or change the state of the indicator based on the message signal; and

a transmitter configured to transmit a range signal to the base station periodically;

wherein receipt of the range signal by the base station is an indication to the base station that the mobile station is within a proper range to receive the message signal from the base station.

8. The mobile station of claim 7, wherein the mobile station has a mobile station address, and wherein the message signal includes a message signal address.
