Abstract

Timing trilateration requires timing information from three herbal UMTS base stations to accurately predict the position of mobile users. But, when only the serving UMTS cell is hearable, the Round Trip Time (RTT) of the cell is used, along with Telco's beamwidth information, and a new technique called One Cell Road Angle Algorithm (OCRAA) to determine the proximity of the mobile users' location. OCRAA ensures that the stored road point falls within the serving cell's coverage based on a pre-calculated variable called Average Beamwidth (Abwt) for the antenna configuration of all cells covering the map's road points. For an urban road in Kuala Lumpur (Malaysia), the simulation results produced location accuracy error of 65 meters for 95% of the experiment's data, which is considered very desirable for navigational services.
