TELECOMMUNICATION SYSTEM FOR AUTOMATICALLY LOCATING BY NETWORK CONNECTION AND SELECTIVELY DELIVERING CALLS TO MOBILE CLIENT DEVICES
First Claim
1. A dual-mode communication device, comprising:
- microphone and speaker apparatus including converters for rendering audio data as audible speech, and for rendering audible speech as audio data;
a first communication interface comprising circuitry for receiving and sending the audio data on a cell-phone network; and
a second communication interface comprising circuitry for connecting to a local area network (LAN), and for receiving and sending the audio data on the LAN.

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.

11. An IP Local Area Network (IP-LAN) system, comprising:
-
an IP telephony server connected on the LAN and to a publicly-switched telephony trunk; and control routines executing on the IP telephony server; wherein the IP telephony server assigns a temporary IP address to a cell phone-capable device connecting on the LAN, and communicates the fact of connection and a destination number for the IP telephony server to a PSTN-connected routing server. - View Dependent Claims (12, 13, 14, 15)

16. A method for minimizing cell phone charges for an organization having multiple sites, comprising steps of:
-
(a) providing an IP-LAN at least one organization site, the LAN having a PSTN-connected IP server; (b) providing at least one dual-mode communication device for use by organization personnel, the device capable of connection and communication on both a cell-phone network and on the LAN; (c) assigning a temporary IP address to the one or more dual-mode communication devices upon connection to the LAN; (d) associating the IP address with the cell phone number of the dual-mode communication device at the IP server; (e) communicating the cell phone number and a destination number for the IP server to a PSTN-connected router; and (f) routing calls for the cell phone number to the dual-mode communication device via a cell phone network during time the dual-mode device is not logged on to the LAN, and to the IP server for routing on the LAN during time the device is logged on to the LAN. - View Dependent Claims (17, 18)
