Abstract

An Applications Processor (14) including a centralized database system is used in a wireless location system (WLS). The APs 14 may be used to manage resources in the WLS, including signal collection systems (SCSs 10) and TDOA location processors (TLPs 12). Each AP 14 contains a database containing triggers for the WLS. The WLS can be programmed to locate only certain pre-determined types of transmissions. When a transmission of a pre-determined type occurs, then the WLS is triggered to begin location processing. Each AP 14 also contains applications interfaces that permit a variety of applications to securely access the WLS. These applications may access location records in real time or non-real time, create or delete certain types of triggers, or cause the WLS to take other actions. Each AP 14 is also capable of certain post-processing functions.
