Abstract

A wireless office architecture, and method of operation thereof, including: (1) a private branch exchange (PBX) having a wired extension and (2) a wireless base station, couplable to the PBX and having a wireless terminal, the wireless terminal associated with the wired extension to allow the wireless base station and the PBX to cooperate to manage the wireless terminal and the wired extension as a unified extension, the wireless base station and the wireless terminal communicating according to a public network standard protocol to allow the wireless terminal to interact both with the wireless base station and in the public network.

Claims

1. A wireless office architecture, comprising:

a private branch exchange (PBX) having a wired extension; and

a wireless base station, couplable to said PBX and having a wireless terminal, said wireless terminal associated with said wired extension to allow said wireless base station and said PBX to cooperate to manage said wireless terminal and said wired extension as a unified extension, said wireless base station and said wireless terminal communicating according to a public network standard protocol to allow said wireless terminal to interact both with said wireless base station in an on-premise dialing plan and in said public network, said wireless terminal having access to at least one feature of said PBX as said wireless terminal communicates via said public network, said on-premise dialing plan allowing said wireless terminal to call extensions of said PBX using an extension number and receiving calls via a directory number even when said wireless terminal is outside a building housing said PBX.

2. The architecture as recited in claim 1 wherein said wireless base station is a wireless station in said public network and said wired extension and said wireless terminal share said at least one feature.

3. The architecture as recited in claim 1 wherein said wireless base station routes calls from said wireless terminal to another wired extension of said PBX based only on a dialed extension number.

4. The architecture as recited in claim 1 wherein said wireless base station is located proximate said PBX.

5. The architecture as recited in claim 1 wherein said wireless base station routes calls received from a wireless terminal dissociated from said PBX.

6. The architecture as recited in claim 1 wherein said wireless terminal is selected from the group consisting of:

a wireless telephone,

a pager, and

a wireless facsimile machine.

7. The architecture as recited in claim 1 wherein said wireless base station is coupled to a local area network (LAN) said wireless terminal being a computer.

8. A method of routing a call to a given extension number of a private branch exchange (PBX) through a wireless office architecture, comprising the steps of:

routing said call to said PBX, said PBX having a wired extension having said given extension number;

alerting a wireless base station, couplable to said PBX and having a wireless terminal, said wireless terminal also having said given extension number to allow said wireless base station and said PBX to cooperate to manage said wireless terminal and said wired extension as a unified extension having said given extension number; and

ringing both said wired extension and said wireless terminal, said wireless base station and said wireless terminal communicating according to a public network standard protocol to allow said wireless terminal to interact both with said wireless base station in an on-premise dialing plan and in said public network, said wireless terminal having access to at least one feature of said PBX as said wireless terminal communicates via said public network, said on-premise dialing plan allowing said wireless terminal to call extensions of said PBX using an extension number and receiving calls via a directory number even when said wireless terminal is outside a building housing said PBX.

9. The method as recited in claim 8 wherein said wireless base station is a wireless station in said public network and said wired extension and said wireless terminal share said at least one feature.

10. The method as recited in claim 8 further comprising the step of routing calls from said wireless terminal to another wired extension of said PBX based only on a dialed extension number.

11. The method as recited in claim 8 wherein said wireless base station is located proximate said PBX.

12. The method as recited in claim 8 further comprising the step of routing calls received from a wireless terminal dissociated from said PBX.

13. The method as recited in claim 8 wherein said wireless terminal is selected from the group consisting of:

a wireless telephone,

a pager, and

a wireless facsimile machine.

14. The method as recited in claim 8 wherein said wireless base station is coupled to a local area network (LAN), said wireless terminal being a computer.

15. A wireless office architecture, comprising:

a private branch exchange (PBX);

a plurality of wired extensions coupled to said PBX;

a wireless base station, coupled to said PBX; and

a plurality of wireless terminals couplable to said wireless base station and corresponding to said plurality of wired extensions to allow said wireless base station and said PBX to cooperate to manage said pluralities of wireless terminals and wired extensions in tandem, said wireless base station and said wireless terminal communicating according to a public network standard protocol to allow said plurality of wireless terminals to interact both with said wireless base station in an on-premise dialing plan and in said public network, said wireless terminal having access to at least one feature of said PBX as said wireless terminal communicates via said public network, said on-premise dialing plan allowing said wireless terminal to call extensions of said PBX using an extension number and receiving calls via a directory number even when said wireless terminal is outside a building housing said PBX.

16. The architecture as recited in claim 15 wherein said wireless base station is a wireless station in said public network and said wired extension and said wireless terminal share said at least one feature.

17. The architecture as recited in claim 15 wherein said wireless base station routes calls from said wireless terminal to another wired extension of said PBX based only on a dialed extension number.

18. The architecture as recited in claim 15 wherein said wireless base station is located proximate said PBX.

19. The architecture as recited in claim 15 wherein said wireless base station routes calls received from a wireless terminal dissociated from said PBX.

20. The architecture as recited in claim 15 wherein said wireless terminal is selected from the group consisting of:

a wireless telephone,

a pager, and

a wireless facsimile machine.

21. The architecture as recited in claim 15 wherein said wireless base station is coupled to a local area network (LAN), said wireless terminal being a computer.
