Abstract (en)

[origin: WO9916276A2] The invention relates to a mobile telephone system comprising a number of coverage areas, each coverage area being served by at least one base station (100), a number of subscriber terminals (106, 108) communicating with one or more base stations, and from which terminals at least some are arranged to determine their geographical location and to inform the base station of the location. The terminals are arranged to inform the base station of their geographical location at certain intervals. To improve the call set-up quality of the terminal, the base station is arranged to store one or more location information items transmitted by each terminal, and to determine the direction of travel and the speed of the terminal on the basis of the location information transmitted by the terminal.
