A Bluetooth-wireless docking station for use with a Bluetooth-enabled
cellular mobile handset, which docking station allows mobility to the
cellular mobile handset rather than having to be fixed stationarily in the
docking station, which docking station couples standard POTS telephone
sets, or POTS-like telephone units, connected to in-premises wiring, to
the cellular, or cellular like, network. The cellular mobile handset may
be used to make or receive calls remote from the docking station, while
the docking station communicates with the Bluetooth-enabled cellular
mobile handset via a Bluetooth-wireless transceiver using
Bluetooth-wireless air-interface protocol. A subscriber-line interface
circuit, controlled by a microprocessor, couples the standard POTS
telephone sets to the cellular mobile handset's transceiver whereby the
phones may make or receive calls via the cellular, or cellular like,
network, which subscriber line interface also provides loop current, ring
signaling, dial tone, loop current detect, flash detection, DTMF
conversion, and other central office functions to the telephone sets. As
long as the cellular mobile handset is within range of the
Bluetooth-wireless transceiver of the docking station, the telephones are
connected to the cellular network, as long as the cellular mobile handset
is not engaged in a call of its own. The same docking station is capable
of accommodating and being paired with any of a wireless-enabled
TDMA-based, GSM-based, CDMA-based, or AMPS-based standard transceiver.
