Abstract

The present invention is a wireless network system, which comprises at least one wireless instrument (e.g. a cellular telephone) in combination with at least one cradle (e.g. a telephone cradle), said cradle comprising a wireless local area network (WLAN) interface. The WLAN interface, which interfaces to a WLAN, allows the cradle to communicate with a controller. In turn, the controller communicates with a base station of a wireless communications network. In a variation of the exemplary embodiment, a wired local area network (LAN) can be utilized rather than the WLAN. Alternatively, the present invention supports point-to-point communication configurations between each wireless cellular telephone and the controller. Typically, the base station is owned and operated by wireless service provider. The wireless service provider directly supports service for the wireless cellular telephone when the telephone is not operating in conjunction with the wireless network system.

Claims

1. A wireless network system for supporting at least one wireless instrument, the wireless network system comprising:

a local network;

a first cradle that holds a first wireless instrument and that communicates with the first wireless instrument over a first local wireless channel when the first wireless instrument functions in a local mode state; and

a controller that connects to the first cradle through the local network in order to communicate with the first wireless instrument when the first wireless instrument is engaged with the first cradle and that communicates with a base station over a first radio channel, wherein the base station provides wireless service for the first wireless instrument.

2. The wireless network system of claim 1, wherein the first wireless instrument is engaged with the first cradle corresponding to an occurrence selected from the group consisting of a mechanical engagement with the first cradle, an electrical engagement with the first cradle, and being located in close proximity to the first cradle.

3. The wireless system of claim 1, further comprising:

a second cradle that holds a second wireless instrument and that communicates with the second wireless instrument over a second local wireless channel when the second wireless instrument functions in the local mode state.

4. The wireless network system of claim 1, wherein the controller interfaces to a public switching telephone network (PSTN).

5. The wireless network system of claim 1, wherein the local network comprises a wireless local area network (WLAN).

6. The wireless network system of claim 5, wherein the WLAN supports a specification selected from the group consisting of Institute of Electrical and Electronics Engineers (IEEE) 802.11 and HomeRF Working Group'"'"'s Shared Wireless Access Protocol (swap).

7. The wireless network system of claim 1, wherein the local network supports a point-to-point configuration.

8. The wireless network system of claim 7, wherein the point-to-point configuration is supported in accordance with a Bluetooth specification.

9. The wireless network system of claim 1, wherein the local network comprises a wired configuration.

10. The wireless network system of claim 1, wherein the controller determines that the first wireless instrument is functioning in the local mode state when the first wireless instrument is registered with the controller.

11. The wireless network system of claim 10, wherein the controller de-registers the first wireless instrument.

12. The wireless network system of claim 1, wherein the first wireless instrument and the second wireless instrument communicate with each other through the local network in order to support a wireless service.

13. The wireless network system of claim 3, wherein the second wireless instrument communicates with the first cradle through a third local wireless channel.

14. The wireless network system of claim 1, wherein the controller communicates with the base station over a second radio channel in order to support simultaneous calls.

15. The wireless network system of claim 1, wherein the first cradle recharges a battery of the first wireless instrument.

16. The wireless network system of claim 1, wherein the first wireless instrument is selected from the group consisting of a wireless telephone, a computer, and a personal digital assistant.

17. A method for networking a plurality of wireless instruments through a local network in order to support wireless service for the plurality of wireless instruments, the wireless service being supported by a base station, the method comprising:

(a) registering a first wireless instrument of the plurality of wireless instruments at a controller of the local network;

(b) receiving an indicator of an incoming call for one of the plurality of wireless instruments;

(c) in response to receiving an indicator of the incoming call, initiating ringing at the first wireless instrument;

(d) if the first wireless instrument goes off hook before the other wireless instruments of the plurality of wireless instruments, completing the incoming call to the first wireless instrument.

18. The method of claim 17, further comprising:

(e) in response to (b), if a second wireless instrument is de-registered, not initiating ringing at the second wireless instrument.

19. The method of claim 17, wherein (a) comprises:

if the first wireless instrument is engaged with a first cradle, registering the first wireless instrument.

20. The method of claim 17, wherein (a) comprises:

if the first wireless instrument requests to be de-registered;

de-registering the first wireless instrument.

21. The method of claim 17, wherein (a) comprises:

if the first wireless instrument is not in close proximity to a cradle, de-registering the first wireless instrument.

22. The method of claim 17, wherein (a) comprises:

if the first wireless instrument requests an outgoing call, de-registering the first wireless instrument.

23. A wireless instrument that interacts with a wireless network system in order to support wireless services with a base station, the wireless instrument comprising:

a radio channel module that communicates with the base station over a radio channel in order to support the wireless services when the wireless instrument is functioning in a normal mode state;

a local wireless module that communicates with the wireless network system through a local network over a local wireless channel in order to support the wireless services when the wireless instrument is functioning in a local mode state; and

a processor that determines to activate the local wireless module when functioning in the local mode state, the processor configured to perform the steps of;

(a) registering with the wireless network system;

(b) receiving an instruction to initiate ringing in response to a delivery attempt of an incoming call;

(c) completing the incoming call with the wireless network system through the local wireless module; and

(d) if the wireless instrument enters into the normal mode state, de-registering with the wireless network system.

24. The wireless instrument of claim 23, further comprising:

a display module that indicates whether the wireless instrument is functioning in either the local mode state or the normal mode state.

25. A wireless network controller for supporting at least one wireless instrument, the wireless network controller comprising:

a radio module that communicates with a base station over a radio channel;

a wireless network module that communicates with a wireless instrument, wherein the wireless instrument is one of the at least one wireless instrument; and

a processor that interfaces with the radio module and the wireless network module, the processor configured to perform the steps of;

(a) registering the wireless instrument through the local network module;

(b) receiving an indicator of an incoming call for the wireless instrument;

(c) in response to step (a) and step (b), sending an instruction to initiate ringing for a delivery attempt of the incoming call;

(d) completing the incoming call with the wireless terminal through the local network module; and

(e) in response to determining that the wireless instrument is not functioning in a local mode state, de-registering the wireless instrument.
