Paging receiver for storing digitized voice messages
First Claim
1. A paging receiver comprising:
- receiving means for receiving selective call signals intended for said paging receiver, wherein the selective call signals include at least one analog voice message for said paging receiver;
decoding means responsive to said selective call signals for enabling said paging receiver to recover said analog voice message;
conversion means responsive to said receiving means and said decoding means for converting said analog voice message to digital signals representative of a replica of the analog voice message;
memory means including at least one fixed capacity storage area for storing digital signals;
means for sensing the end of the recovered analog voice message and generating an end of message signal in response thereto;
signal producing means for generating predetermined digital signals;
control means for accessing said memory means to store in a portion of a selected fixed capacity storage area thereof the converted digital signals of said analog voice message during the conversion thereof by said conversion means and, governed by said end of message signal, to access said memory means to store in the remaining portion of said selected fixed capacity storage area the predetermined digital signals during the generation thereof; and
means for inhibiting memory accessing by said control means when the remaining portion of said selected fixed capacity area is filled.

Abstract
A selective call paging receiver for receiving analog voice information converts the analog information to digital information and stores the digital information in a memory of the paging receiver. In a first embodiment, the paging receiver includes a hardware controlled decoder and an audio producing module. The memory is divided into a plurality of fixed storage areas to allow the decoder to store a digitized voice message in a fixed storage area. If the storage capacity of the fixed storage area is not filled, the audio producing module fills the remainder in a predetermined bit pattern. In a second embodiment, the paging receiver includes a microprocessor controlled decoder. The microprocessor stores a digitized voice message in the memory, depending upon the length of the voice message, thus eliminating the fixed storage area.
