Abstract

Recently, geolocation technologies in mobile telephony are rapidly advancing. Geographical location data of mobile phone users, which are acquired automatically, will be effectively utilized to provide local information. In Japan, the first geolocation service using the location data of base stations of PHS service started in 1997. This service has applied to location tracking services for children, elders or emergencies and the management of delivery cars. In the case of cellular phone, the precision of location data acquired by base station data are more limited than PHS because of the wideness of the service area of a base station. Despite the limited precision, the location data by cellular phone using base station data can be utilized for the purpose of the local information provision. Japanese cellular phone companies started the geolocation services for local information providers around 2000. 'i-Area' service by NTTdocom is the most typical of these services. More precise geolocation services have been provided by cellular phone companies since 2001, when new methods for location data acquisition using GPS technology were developed. Various new services in local information provision utilizing precise location data, e.g. detail guides of restaurants/shops, and navigations services for pedestrians are now diffusing. In this presentation, I will overview the geolocation services using mobile phone and discuss the possibilities of geolocation technologies for new local information services.
