Abstract
A wireless telephone system, having one or more wireless handsets and a base unit. Each handset has a handset transceiver, and the base unit has a base transceiver and a handset docking station, which has a wired interface. The base unit digitally communicates over an RF channel with a handset via its handset transceiver only if the handset has previously been initialized by the base unit. The handset is initialized via the wired interface when it is physically docked in the docking station.
Claims12
A wireless telephone system, comprising:
- (a) one or more wireless handsets, each handset comprising a handset transceiver;
- and
- (b) a base unit comprising:
- (1) a handset docking station having a wired interface;
- (2) means for initializing the handset via the wired interface, when the handset is physically docked in the docking station, by reading from the handset a unique handset security code based on but not the same as a unique handset serial number permanently stored in the handset and storing the unique handset security code locally to the base unit;
- and
- (3) a base transceiver for communicating over a channel with each handset via its handset transceiver only if the base unit determines, upon receipt of the handset security code for said handset from the handset, that the handset has previously been initialized by the base unit.
A method for providing communication between a base unit of a wireless telephone system and on or more wireless handsets of the system, the base unit comprising a base transceiver and handset docking station having a wired interface, each handset comprising a handset transceiver, a method characterized by the steps of:
- (a) initializing a handset via the wired interface, when the handset is physically docked in the docking station, by reading from the handset a unique handset security code based on but not the same as a unique handset serial number permanently stored in the handset and storing the unique handset security code locally to the base unit;
- and
- (b) conducting digital communications, over an RF channel, between the base unit and the handset via the base unit and handset transceivers, respectively, only if the base unit determines, upon receipt of the handset security code for said handset from the handset, that the handset has previously been initialized by the base unit.
A base unit for communication with one or more wireless handsets, each handset comprising a handset transceiver, comprising:
- (a) a handset docking station having a wired interface, the base unit characterized by further comprising:
- (b) means for initializing the handset via the wired inter face, when the handset is physically docked in the docking station, by reading from the handset a unique handset security code based on but not the same as a unique handset serial number permanently stored in the handset and storing the unique handset security code locally to the base unit;
- and
- a base transceiver for communicating over a channel with each handset via its handset transceiver only if the base unit determines, upon receipt of the handset security code for said handset form the handset, that the handset has previously been initialized by the base unit.
