Abstract

A selective call receiver with memory is described for use in a system providing user initiated alteration of the content of the memory using reconfiguration information transmitted from an external source. The receiver comprises a circuit for generating a user activated programming authorization signal, a receiver for receiving the transmitted reconfiguration information, and a circuit for altering the content of the memory in response to the received reconfiguration information only in the presence of the user activated programming authorization signal.

Claims

1. In a selective call receiver having a memory capable of being altered by reconfiguration information transmissions received over-the-air, an improvement comprising:

means for receiving the reconfiguration information for altering the memory;

means for altering the memory; and

means, operable by the receiver user, for allowing such alteration to occur when the reconfiguration information is received during a predetermined programming time interval.

2. A method for user initiated alteration of a memory in a selective call receiver, using reconfiguration information corresponding to the memory alteration selected by the user and transmitted from an external source, said method comprising the steps of:

generating, for a predetermined programming time interval, a programming authorization signal activated by the user;

receiving the transmitted reconfiguration information; and

altering the memory in response to the received reconfiguration information only in the presence of the programming authorization signal.

3. A selective call receiver, having a memory, for use in a system providing user initiated alteration of the memory using reconfiguration information corresponding to the memory alteration selected by the user and transmitted from an external source, said receiver comprising:

means for generating, for a predetermined programming time interval, a programming authorization signal activated by the user;

means for receiving the transmitted reconfiguration information; and

means for altering the memory in response to the received reconfiguration information only in the presence of the programming authorization signal.

4. The selective call receiver according to claim 3 comprising means responsive to the completion of the memory alteration for terminating the generation of the programming authorization signal prior to the completion of the predetermined programming time interval.

5. The selective call receiver according to claim 4 further comprising means for alerting the user when the memory alteration is completed.

6. The selective call receiver according to claim 4 further comprising means for alerting the user when the memory alteration is not completed within the predetermined programming time interval.

7. A method for altering a memory in a selective call receiver using a notification signal for requesting programming authorization by the selective call receiver user and reconfiguration information transmitted from an external source, said method comprising the steps of:

receiving the notification signal and generating a sensible alert is response thereto;

generating, for a predetermined programming time interval, a programming authorization signal activated by the user in response to the sensible alert being generated;

receiving the transmitted reconfiguration information; and

altering the memory in response to receiving the reconfiguration information in the presence of the programming authorization signal.

8. A selective call receiver with a memory, for use in a system providing a notification signal for requesting programming authorization by the selective call receiver user for altering the memory using reconfiguration information transmitted from an external source, said receiver comprising:

means for receiving the notification signal and for generating a sensible alert in response thereto;

means, for generating, for a predetermined programming time interval, a programming authorization signal activated by the user in response to the sensible alert being generated;

means for receiving the transmitted reconfiguration information; and

means for altering the memory in response to the received reconfiguration information only in the presence of the programming authorization signal.

9. A method for altering a memory in a radio operating in an acknowledge back system providing a transmitted notification signal requesting programming authorization by the radio user, and reconfiguration information, said method comprising the steps of:

receiving the notification signal and generating a sensible alert in response thereto;

determining the memory space available in response to the receipt of the notification signal;

generating and transmitting an acknowledgement signal indicative of memory space availability;

generating a programming authorization signal activated by the user in response to the sensible alert being generated;

receiving the reconfiguration information transmitted in a form consistent with the memory space available; and

altering the memory with the received reconfiguration information when the programming authorization signal is present.

10. The method according to claim 9, wherein aid memory includes a message memory portion, and wherein aid method further comprising the steps of:

determining the status of certain messages stored in the message memory portion in response to receiving the notification signal; and

generating a sensible alert signaling the radio user of impending loss of the certain messages when the reconfiguration information is received and the memory is altered.

11. The method according to claim 10 wherein said step of transmitting an acknowledgement signal further comprises the step of transmitting an acknowledge back signal requesting the reconfiguration information transmission be delayed when certain messages are present.

12. The method according to claim 11, wherein a query signal is periodically transmitted following the request to delay transmission of the reconfiguration information, and wherein said method further comprising the steps of:

receiving a query signal requesting the present status of the certain messages in the message memory portion; and

transmitting an acknowledge back signal corresponding to the present message memory status.

13. The method according to claim 12 further comprising the step of cancelling the transmission of the reconfiguration information when the present message status is unchanged after a predetermined number of query transmissions.

14. A radio, having a memory for operation in an acknowledge back system which provides a transmitted notification signal for requesting programming authorization by the radio user, and reconfiguration information, said radio comprising:

means for receiving the transmitted notification signal;

means for generating a sensible alert in response to receiving the notification signal;
