Abstract: GPS map data on golf courses is collected in a database, through a network when necessary. GPS golf-course map data is sent to users through the network. The fee to be paid by each user and the payment to be made to the person or organization that has the right to the map data is controlled. A golf player can obtain GPS golf-course map data on various golf courses in the same way, easily and at a low price, using a user terminal device, making use of GPS golf-course map data for play by manipulating the user's own user terminal device. Optional information is added to GPS golf-course map data, which the user can choose as needed. Optional information can also be presented based on the records of use of a particular user.

Abstract: In a mobile radio telephone system having multiple base stations controlled by a single line control unit, all base stations use a single common control channel in addition to their voice channels to communicate with a mobile station. If a calling signal from a mobile station is received by two or more base stations at once on the common control channel, the base station with the highest received signal level is selected. If voice signal quality becomes degraded during a call, the call is handed off to the base station with the highest received signal level.
