Abstract

A device and method are disclosed for saving stored messages in a digital stored voice paging receiver. The digital stored voice paging receiver includes a plurality of message slots, each slot capable of storing a digitized voice message. A status value associated with a message slot is representative of the status of the message in the slot. A first embodiment of the method stores messages in the message slots by chronologically replacing older messages. A second embodiment of the method orders the stored messages in a predetermined priority. A stored message is replaced by an incoming message when the incoming message priority status is greater than the stored message priority status.

Claims

1. A method of storing in a fixed memory area of a paging receiver analog voice messages transmitted thereto from a remote source, said fixed memory area including a fixed number of storage slots with each slot capable of storing only one digitized voice message, said method comprising the steps of:

(a) receiving and digitizing a transmitted analog voice message to recover a new digitized voice message replica thereof;

(b) setting said paging receiver in one of a first mode to audibilize said transmitted analog voice message upon receipt or a second mode to not audibilize said transmitted analog voice message upon receipt;

(c) initially assigning said new digitized voice message replica a priority status based on said mode setting corresponding thereto;

(d) thereafter, storing said new digitized voice message replica and its assigned priority status in an empty storage slot of said fixed memory area, and if there are no empty storage slots of said fixed memory area, storing said new digitized voice message replica and its assigned priority status in a selected storage slot based on a predetermined priority relationship between the currently stored voice message of said selected storage slot and the other currently stored voice messages of said fixed memory area, thereby replacing said currently stored voice message of the selected storage slot with said new voice message.

2. A method in accordance with claim 1 including the steps of:

assigning a storage status to each voice message being stored in the storage slots of the fixed memory area in accordance with the storage chronology thereof, said storage status ranging from the oldest to the newest; and

storing the new digitized voice message replica in the selected storage slot based solely on the storage status of the currently stored voice message thereof when said fixed memory area is filled with currently stored voice messages.

3. A method in accordance with claim 2 wherein the new digitized voice message replica is stored in the selected storage slot having a currently stored message with the storage status of the oldest.

4. A method in accordance with claim 1 including the steps of:

assigning a storage status to each voice message being stored in the storage slots of the fixed memory area in accordance with the storage chronology thereof, said storage status ranging from the oldest to the newest; and

storing the new digitized voice message replica in the selected storage slot based on both of the priority status and storage status of the currently stored voice message thereof.

5. A method in accordance with claim 4 wherein the initially assigning step includes assigning a read priority status corresponding to the first mode and an unread priority status corresponding to the second mode.

6. A method in accordance with claim 5 including the step of reassigning the unread priority status of a currently stored voice message to a read priority status when said voice message is first audibilized by the paging receiver.

7. A method in accordance with claim 6 wherein the new digitized voice message replica is stored in the selected storage slot having a currently stored voice message which is the oldest stored, unread voice message of the fixed memory area.
