Mobile access to telecommunications network
First Claim
1. In a telecommunications system including a switched telecommunications network having switching means interconnected by trunk means and station means linked to at least certain of said switching means, the improvement comprising;
- at least certain of said station means comprising fixed site transceiver means;
portable transceiver means including signal input means and signal output means and transmitter means and receiver means capable of communicating with said fixed site transceiver means;
first storage means associated with said portable transceiver means;
means coupling said input signal means of said portable transceiver means with said first storage means to store in said first storage means a signal from said input signal means;
means associated with said portable transceiver means to couple said first storage means with said transmitter means to transmit a signal stored in said first storage means;
control means associated with said portable transceiver means to initiate transmission by said transmitter means;
second storage means associated with said switched telecommunications network for storing signals received from said transmitter means;
means associated with said switched telecommunications network to couple said second storage means to at least one of said station means to provide at said station means a readable output of signals stored in said second storage means.

Abstract
A method and system for providing mobile access to message delivery into the existing public telecommunications network. A portable handset and transceiver have storage capacity and a processor for digitizing and time compressing messages inputted by the operator into the handset. Upon command of the handset operator the stored message is transmitted to a fixed site transceiver having storage capacity. The two transceivers are locked into communication by suitable handshake protocols. The fixed site transceiver is linked to the public switched telecommunications network and delivers the message stored in the fixed site storage to voice messaging service storage in the public telecommunications network. The message thus stored is either delivered as by call completion service or retrieved by the addressee as in voice mail service. In both cases the signal from the VMS storage is processed to perform digital to analog conversion along with time decompression or expansion. The addressee, handling procedures, and billing information are incorporated into the original message in the handset transceiver. Periodic beacon signals may be provided at the fixed site transceiver to facilitate location thereof by the portable handset and transceiver.
