Network and method for monitoring location capabilities of a mobile station
First Claim
1. A method for monitoring location capabilities of mobile stations using a communication network, the communication network including a database for storing the location capabilities, the method comprising the steps of:
- receiving an identification number from a mobile station;
creating an entry in the database corresponding to the identification number;
receiving a location capability from the mobile station;
storing the location capability in the database;
assembling an assistance message based on the location capability of the mobile station, the assistance message including location calculation parameters of the mobile station;
transmitting the assistance message to the mobile station; and
updating the database with statistical information about the mobile station the statistical information including at least one of an instantaneous circular error probability and a cumulative circular error probability in the database.

Abstract
The present invention is a communication network (100) and method for monitoring location capabilities of mobile stations (102) in a database (120) of a communication network. Initially, the network receives an identification number from a mobile station (102). If the database (120) does not include a location capability corresponding to the identification number, then a processor (118) requests the location capability from the mobile station (102) and stores the requested location capability in the database (120). The location capability includes one or more of the following capabilities: an autonomous mode capability, an assisted mode capability and a legacy mode capability. To retrieve an entry from the database (120), the network reads the location capability corresponding to the identification number from the database (120). The network then assembles an assistance message based on the location capability of the mobile station (102) and transmits the assistance message to the mobile station (102).
