SYSTEM AND METHOD FOR DETERMINING DEVICE LOCATION IN AN IP-BASED WIRELESS TELECOMMUNICATIONS NETWORK
First Claim
1. A system for determining a location associated with a mobile device in a IP-based wireless telecommunications network, the system comprising:
- a network controller that is arranged to identify data associated with the mobile device;
a location database that is arranged in communication with the network controller, wherein the location database is arranged for indexing with the identified data associated with the mobile device;
a means for communicating a query from the network controller to the location database that includes the identified data associated with the mobile device; and
a means for communicating a reply from the location database to the network controller in response to the query, wherein the reply includes location information associated with the mobile device.

Abstract
A system and method determines a geographic position of a mobile device in communication with an IP-based wireless telecommunications network. A wireless connection between the mobile device and the IP-based wireless telecommunications network is established when the mobile device registers with a network controller (NC) through an access point (AP). When a geographical position is needed for the mobile device (e.g., a 911 call), messages are exchanged between the NC and the SMLC, where the SMLC retrieves information from a database that is used to identify the geographic position of the mobile device. The database can store a variety of information related to mobile devices such as: last known position, IP address, MAC address, device or subscriber identifier, last CGI, etc. The geographical position is communicated back to the NC, which can then forward the position information to a switch for processing such as for 911 calls.

18. A serving mobile location center that is arranged in an IP-based wireless telecommunication network that includes facilities for a mobile device, the serving mobile location center comprising:
-
a means for receiving a perform location request (PLRQ) message from a network controller, wherein the PLRQ message is associated with the mobile device; a means for communicating an IP-based wireless telecommunication network positioning request message to the network controller in response to the PLRQ message; a means for receiving a positioning response message from the network controller after communicating the positioning request message; a means for processing the positioning response message to determine a geographical position associated with the mobile device; and a means for communicating a perform location response (PLRS) message to the network controller such that the network controller is operative to communicate the determined geographical position associated with the mobile device to a mobile switching center. - View Dependent Claims (19, 20, 21, 22, 23)
