Abstract
A Network Autonomous Wireless Location System (NAWLS) is designed to allow for precise location of a mobile device (e.g., a cell phone) without interconnection to, and with minimal disruption of, the local wireless communications network. Using distributed radio network monitors (RNM) and a managed network emulator (NE); mobile devices are sampled, acquired or captured. Once triggered by the RNM or NE, an untethered wireless location system (U-WLS) is used to calculate a precise location. The U-WLS; comprising mobile receiver sites, each capable of self location, exchanging information with other components of the NAWLS, and receiving or exchanging signals from the mobile device; utilizes various network-based and handset-based wireless location techniques dependent on the deployed options. In addition, the NAWLS includes data links interconnecting the U-WLS, NE and RNM.
