Telephony device with data repeater
First Claim
1. A telephony device for communicating data between a communications network and an external data communications device during a telephone call carried by the telephony device, comprising:
- an interface circuit for interfacing the telephony device to the communications network;
a wireless data communications port for communicating data to and from the external communications device across a wireless link; and
a control unit coupled to the wireless communications port for processing data received from the external communications device and sending such data to the interface circuit for transmission to the communications network during the telephone call and for processing data received from the communications network via the interface circuit for transmission to the external data communications device via the wireless data communications port during the telephone call.

Abstract
A telephony device (101) communicates data between an external communications device (111), such as a laptop computer or Personal Data Assistant, and a communications network (12) via a wireless link while the telephony device carries a telephone call between the network and a telephone (20, 28). A control unit (22, 24) within the telephony device multiplexes data received from the external data communication device via a wireless data communications port for communication via an interface circuit (16, 161) to the communications network during the call. Further, the control unit de-multiplexes data received from the network via the interface circuit for communication to the external data communications device over the wireless link during the call.

19. A method for communicating data between a communications network and an external data communications device during a telephone call, comprising the steps of:
-
establishing the telephone call with the network to send and receive call audio;
receiving, via a wireless link, outbound data from an external data communications device destined for the network multiplexing the outbound data from the external device onto the call audio for transmission to the network;
de-multiplexing inbound data from the network off the call audio; and
transmitting the inbound data via the wireless link to the external data communications device.
