Abstract

A radiation detection method and apparatus thereof for estimating radiation power received by the mobile station. The locations of nearby base stations and the mobile station are obtained from the broadcast system messages and the location service provided by the service provider, and based on the location information, the radiation power is estimated according to the distances between the base stations and the mobile station. In addition, the radiation estimation process also utilizes the radiation power of monitored base stations constantly measured by the mobile station for cell selection to determine the effects of interference. Based on a preset safety value and the estimated radiation power, the radiation detection device of the present invention automatically issues an alert when entering a high radiation environment.

Dependent claims

A method for a mobile station to detect and estimate radiation power received thereby, comprising the following steps:

obtaining a current mobile station location;
generating a base station combination and corresponding base station information, wherein the base station combination and the corresponding base station information are retrieved by searching in a first database while using location information of a serving base station as a search index, the base station combination comprising the serving base station and nearby base stations close to the serving base station;
calculating a distance between the mobile station and each base station listed in the base station combination according to the current mobile station location and the base station information in the base station combination;
estimating total radiation power by substituting calculated distances into a predetermined equation;
checking whether the total radiation power is greater than a preset minimal safety value;
and
informing the mobile user if the total radiation power is greater than the preset value.
