Abstract

A communication system for an organization having multiple sites uses a dual-mode device capable of both cell phone communication and telephone communication on a local area network (LAN). IP LANS are established at organization sites such that a temporary IP address is assigned to a dual-mode device that logs onto an organization LAN, and the IP address is associated at a PSTN-connected server on the LAN with the cell phone number of the communication device. The IP server notifies a PSTN-connected routing server when a device logs on to a LAN, and also provides a destination number for the IP server. Cell calls directed to the device are then redirected to the IP server and directed to the device connected to the LAN.

Claims

1-18. -18. (canceled)

19. A mobile communication device comprising:

software enabling user selection of a network for communication, and enabling implementation of transmission and receipt of data in a format compatible with the selected network; and

plural physical interfaces for connecting to individual ones of the selectable networks.

20. The device of claim 19 wherein the selectable networks include two or more of a Public Switched Telephone Network (PSTN), a cellular telephone network, a Local Area Network (LAN) and an Internet Protocol (IP) packet network.

21. The device of claim 19 wherein the physical interfaces comprise two or more of a wireless interface to a cellular system, a connection interface to a local area network, and a receptacle for a Connection-Oriented Switched Telephony (COST) telephone line.

22. The device of claim 20 wherein the software, upon connection to a LAN, cooperates with software in communication with the LAN to assign a temporary IP address to the device for IP communication.

23. A method for enhancing communication using a mobile device, comprising steps of:

(a) providing the mobile device with software enabling user selection of a network for communication, and enabling implementation of transmission and receipt of data in a format compatible with the selected network; and

(b) providing the mobile device with plural physical interfaces for connecting to individual ones of the selectable networks.

24. The method of claim 23 wherein in step (a) the selectable networks include two or more of a Public Switched Telephone Network (PSTN), a cellular telephone network, a Local Area Network (LAN) and an Internet Protocol (IP) packet network.

25. The method of claim 23 wherein in step (b) the physical interfaces comprise two or more of a wireless interface to a cellular system, a connection interface to a local area network, and a receptacle for a Connection-Oriented Switched Telephony (COST) telephone line.

26. The method of clam 24 wherein the software, upon connection to a LAN, cooperates with software in communication with the LAN to assign a temporary IP address to the device for IP communication.
