Abstract

PURPOSE:To attain the control of connection with high efficiency, by connecting numbers of base radio stations which are distributed with extremely high density to the terminals of the end offices in an ordinary telephone network. CONSTITUTION:A mobile control station is set at a lower position of an end office EO in the stage of exchange in a telephone network. A mobile control center is set at a position equivalent to a trunk exchange stage comprising an office rank of a toll center TC, a district center DC and a regional center RC. For a call given from a mobile telephone, the circuit is connected in the same procedure as the connection of circuit in a telephone network from the office EO. For an incoming call to the mobile telephone, a circuit is once set to the mobile control center from the office EO or the centers TC, DC and RC. In a range from the mobile control center to the incoming side end office EO where the mobile telephone exists, there is connected by the telephone network.

The line configuration of current car telephones is as shown in FIG. In FIG. 1, Re is an abbreviation for a general office, DC is a central office, TC is an abbreviation for a central office, and EO is an abbreviation for an end office, which represents the switching hierarchy in a general telephone network.

AMC is a mobile telephone exchange, MC8 is a radio network control center,
MBS is an abbreviation for wireless base station. There is one AMC station in each of the Tokyo and Osaka service areas, and MC8 has a few laps per AMC, and MBS has one station per AMC.
There are several rounds per 8 or more. When calling from a landline phone to a car phone, the subscriber must, for example, call 030-31~XXXX
Dial XX. 030 is an identification number representing a car phone, 31 is a number representing the current location of the car, and 31 shows an example of Tokyo.

xxxxxx is the subscriber number of the car phone. At 030, I learned that the call was to a car phone on EO and TC of the general telephone network, and then at 031, I heard that the call was to an AM in Tokyo.
It is connected to C, and then AMC and MC8.

In the case of a car phone, since the range of movement of the car is wide, the area covered by the MBS consists of small zones with a radius of several tens of meters. Further increasing the subscriber capacity can be achieved by further reducing the area of the MBS and increasing the repeat utilization rate of the radio frequency. For example, if a zone configuration with a radius of 500 m can be achieved, the capacity will theoretically be 100 times that of a zone configuration with a radius of 5 km. In actual cases, the utilization rate will be lower than this due to interlaced propagation, but an improvement of at least 10 times can be expected. Such a minimal zone configuration may not be applicable to a car phone because the frequency of channel changes during a call is extremely high considering the speed at which the car is running; however, in the case of a mobile phone, is quite conceivable.

When configuring such a small zone, a wireless base station (MBS)
are installed in enormous density and quantity, so it is not necessarily advantageous to install mobile exchanges for toll exchanges like conventional AMCs in terms of processing capacity. Since there are dozens of MBSs per local exchange area, it is more appropriate to think of mobile exchanges as compatible with local exchanges.

The mobile device always registers the location of the existing mobile control station area. This method is similar to the current car telephone system, in which a number identifying each mobile control station is sent in the transmission signal from the base station, and when the mobile unit moves, this mobile control station identification number is This can be realized by a method such as sending a location registration signal when the location changes. A location registration signal from a mobile device is transmitted via a radio base station to a mobile control station, and the mobile control station registers the location of the mobile device with a mobile control center via a control line. The mobile control center has a subscriber mail 41J for each subscriber, and the location information of that subscriber.
