不可能になる。Conventional mobile communication systems are configured as described above, so the service area is fixed, and when service is temporarily required outside the service area, temporary service is required even within the Mayu service area. If the amount of service requested exceeds the processing capacity of the fixed base station, mobile phone call service becomes impossible.

There were problems such as the need to turn it off, which often caused trouble. In addition, when installing or expanding a fixed base station, there is a problem in that it is difficult to set and design communication conditions at the installation destination. This invention aims to solve the above problems. This technology facilitates mobile phone call services outside the area defined by fixed base stations and the expansion of call lines within the area, and also provides a system that does not require hand-off. The purpose of the present invention is to obtain a mobile communication system that can facilitate the design of new or expanded base stations.

実験が行なえる。Since the mobile base station in this invention has the same functions as a conventional fixed base station, the mobile base station is moved to a predetermined position and control conditions such as channel settings and transmission field strength settings are set. You can expand the number of call services on your mobile device with just one simple step. Furthermore, if multiple mobile base stations are moved at regular intervals, a service area with fewer hand-offs can be provided, and furthermore, the mobile base stations can be used to provide communication at locations where fixed base stations are planned to be installed or expanded. Measurement experiments of various conditions can be carried out.
以下、この発明の一実施例を図を用いて説明する。第１

In the figure, (1) to (4) are the same as shown in Figure 3, (6) is a mobile base station, and (6) is the service set in Niimi by the mobile base station. The area boundary (γ) indicates an antenna for communicating information between the MTSO (1) and the mobile base station (6).

If the mobile base station (5) is moved so that an area is created adjacent to the area created by the existing fixed base station, the service area for mobile devices will be expanded in the new station, and the necessary The mobile base station (5) can be removed as soon as it runs out. Furthermore, when a mobile base station (5) is moved within an existing fixed base station area (4), the number of usable channels within the area is increased after setting appropriate conditions. In this case, when the expansion of the channel is no longer necessary, the mobile base station (5
) can be removed.

8) to <5)+ (γ) are the same as in FIG. 1, and (8) is a path along which the mobile device moves, such as a road. For example, as shown in the figure, when multiple mobile base stations (5) are moved at a certain distance (for example, their service areas slightly overlap), mobile stations moving in the same direction on the same path (8) will The number of hand-offs can be reduced. Furthermore, as another example of the mobile base station (5), the mobile base station is temporarily installed at a site where a conventional fixed base station is planned to be newly installed or expanded, and various data for fixed base station design is measured. Then, it is conceivable that measurements can be made under the same conditions as when a fixed base station is actually installed. In the explanation so far, a cellular one-way car phone system has been cited as an example of a mobile communication system related to the present invention, but the present invention is applicable to any mobile communication system other than the cellular one-way car phone system. be.

等の効果がある。As described above, according to the present invention, since the fixed base station is a mobile type, the mobile service area can be easily expanded, and the number of channels used within the existing area can be easily increased. By moving the mobile base station in the same direction as the mobile device, the number of hand-offs can be reduced.Furthermore, the data and conditions necessary when designing new or expanded fixed base stations can be transferred to the non-mobile base station. By temporarily setting up stations, there are effects such as being able to obtain information efficiently and accurately.
