Abstract

The instant invention discloses a method and system for providing a novel wireless centrex service that untethers subscribers from the immobility associated with traditional desktop telephones. Essentially, the present invention extends the benefits of wireless voice and data services to subscribers having a need to move within a plurality of localities such as business and hospital campuses.

In accordance with the invention, a wireless telephone subscriber can use a standard cellular/PCS telephone as a wireless extension of their desktop phone, while in the proximity of a miniature radio base station capable of communicating with the PCS/cellular telephone. The advantage of such a system is that a subscriber can use the same cellular/PCS telephone that provides service in the public network in the wireless centrex environment. Additionally, the wireless centrex system provides services and features which are similar to those offered to regular centrex telephone subscribers. Exemplary features include, caller ID, call waiting, call hold, call transfer, call forwarding and voice messaging.

Claims

1. A method for providing caller identification information for a mobile station in a wireless centrex system including an intelligent radio transceiver, comprising the steps of:

initiating, with said mobile station, a call to another communication device via said intelligent radio transceiver coupled to a local digital switch, said mobile station being registered with said intelligent radio transceiver, said intelligent radio transceiver being further in communication with the local digital switch via a wireline interface without being connected to any public cellular system;

determining, with a network server platform coupled to said local digital switch, said caller identification information based on an identifier of said mobile station; and

providing said caller identification information to said another communication device via said local digital switch and said intelligent radio transceiver.

2. The method according to claim 1, wherein said caller identification is extracted from a data table stored in a database in said network server platform which associates said identifier with said caller identification information.

3. The method according to claim 2, wherein said identifier is a mobile station identification number and said caller identification information includes a desk top telephone number associated with said mobile station.

4. The method according to claim 1, further including the step of including said caller identification information in an available field of a standard call setup signaling message.

5. The method according to claim 4, wherein said caller identification information is forwarded to said mobile station in an alert message.

6. The method according to claim 5, wherein said caller identification information is forwarded to an intelligent transceiver in an origination acknowledgment message.

7. The method according to claim 6, wherein said caller identification information is forwarded to a local digital switch in a setup message.

8. The method according to claim 1, wherein said caller identification includes a directory number for a desktop telephone.

9. A method according to claim 1, wherein said caller identification includes at least one party to a call'"'"'s name.

10. The method according to claim 1, wherein said caller identification includes location information.

11. The method according to claim 10, wherein said location identification includes an address.

13. The method according to claim 1, further including the step of including said caller identification information in a signaling that permits user to user information exchange.

14. The method according to claim 13, wherein said caller identification information is forwarded to said mobile station in an alert message.

15. A method for providing caller identification information for a mobile station in a wireless centrex system including an intelligent radio transceiver, comprising the steps of:

originating, with said mobile station, a call to another communication device via said intelligent radio transceiver coupled to a local digital switch, said mobile station being registered with said intelligent radio transceiver, said intelligent radio transceiver being further in communication with the local digital switch via a wireline interface without being connected to any public cellular system;

determining, with a network server platform, said caller identification information based on an identifier of said mobile station; and

storing said caller identification information, a called party number associated with said another communication device and a number associated with said intelligent radio transceiver.

16. The method according to claim 15, further comprising the step of terminating said call to another communication device by matching said called party number associated with said another communication device and a number associated with an intelligent transceiver.

17. The method according to claim 16, further comprising the step of providing said caller identification information to said another communication device based on said matching.

18. The method according to claim 17, wherein said caller identification information is forwarded to said mobile station in an alert message.
