1. A wireless telephone system, comprising:
- (a) a base unit having a base transceiver; and
(b) a plurality of wireless handsets, each handset comprising a handset transceiver for establishing with the base unit via the base transceiver a time-division multiple access (TDMA) data link and a TDMA audio link, in accordance with a TDMA epoch allocating exclusive data and audio packet time slots to each handset, wherein the data link is for transmitting signaling information and the audio link is for transmitting voice data for a real-time telephone call, wherein the base unit, upon request from a handset for data from a data source, retrieves the requested data from the data source and transmits the retrieved data to the handset via the audio link, wherein;
the epoch has a plurality of transmit and receive data row pairs, wherein each row pair comprises;
an even row comprising a transmit data time slot for a respective handset and a plurality of transmit and receive audio packet time slots for a portion of the maximum number of the plurality of handsets which may be communicating at a time, and an odd row comprising a receive data time slot for the respective handset and a plurality of transmit and receive audio packet time slots for the other portion of the maximum number of the plurality of handsets which may be communicating at a time; and
each handset receives and transmits data packets via the receive and transmit data packet slots only once during each epoch, during the transmit and receive data row pair for each said handset, and, if the handset is communicating with the base unit, each handset receives and transmits audio packets during respective transmit and receive audio packet time slots of each row pair of the epoch.

Abstract
A wireless telephone system comprises a base unit and a plurality of wireless handsets. The base unit has a base transceiver and a memory for storing stored information. Each handset has a handset transceiver for establishing a data link and an audio link with the base unit via the base transceiver, wherein the data link is for transmitting signaling information and the audio link is for transmitting voice data for a real-time telephone call. The handset requests from the base unit certain stored information. In response, the base unit retrieves the requested stored information from the memory and transmits the stored information to the handset via the audio link.

9. In a wireless telephone system comprising a base unit having a base transceiver and a plurality of wireless handsets, each handset comprising a handset transceiver, a method comprising the steps of:
-
(a) establishing, with each handset via its handset transceiver, a time-division multiple access (TDMA) data link with the base unit via the base transceiver, and, with each handset that is communicating with the base unit, a TDMA audio link with the base unit via the base transceiver, in accordance with a TDMA epoch allocating exclusive data and audio packet time slots to each handset, wherein the data link is for transmitting signaling information and the audio link is for transmitting voice data for a real-time telephone call;
(b) requesting, with the handset, from the base unit, data from a data source;
(c) retrieving, with the base unit, the requested data from the data source in response to the request; and
(d) transmitting the retrieved data from the base unit to the handset via the audio link, wherein;
the epoch has a plurality of transmit a receive data row pairs, wherein each row pair comprises;
an even row comprising a transmit data time slot for a respective handset and a plurality of transmit and receive audio packet time slots for a portion of the maximum number of the plurality of handsets which may be communicating at a time, and an odd row comprising a receive data time slot for the respective handset and a plurality of transmit and receive audio packet time slots for the other portion of the maximum number of the plurality of handsets which may communicating at a time; and
each handset receives and transmits data packets via the receive and transmit and receive data row pair for each said handset, and, if the handset is communicating with the base unit, each handset receives and transmits audio packers during respective transmit and receive audio packet time slots of each row pair of the epoch. - View Dependent Claims (10)
