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.
