Telecommunication system for automatically locating by network connection and selectively delivering calls to mobile client devices
First Claim
1. A system for telephone communication, comprising:
- an IP-LAN including an IP telephony server;
a dual-mode communication device comprising a first communication interface having circuitry for receiving and sending audio data on a cell-phone network, including a cell-phone number, and a second communication interface having circuitry for connecting directly to the IP-LAN, and for receiving and sending audio data over the IP-LAN;
a publicly-switched telephone network (PSTN) having a trunk connection to the IP telephony server; and
a PSTN-connected muting server;
wherein the IP telephony server, upon connection of the dual-mode communication device to the IP-LAN, assigns a temporary IP address to the connected device and informs the routing server of the connection and a destination number of the connected device and wherein the routing server then routes calls for the cell phone number to the IP telephony server, which in turn routes the calls on the IP-LAN to the temporary IP address.

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.

6. 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 enabled for connecting directly to the LAN, and communicates the fact of connection and a destination of the connected device to a PSTN-connected routing server. - View Dependent Claims (7, 8, 9, 10)

11. 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 enabled for connecting directly to the LAN, 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 to IP address wit 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 (12, 13)
