Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calling method in a mobile phone such as a car phone or a mobile phone.

[0002]

2. Description of the Related Art In a mobile telephone network such as a car telephone network or a mobile telephone network in Japan, a range where radio waves can reach from a mobile body such as a car telephone or a mobile telephone (this is called a zone or a cell, and a maximum radius is 10 km). A radio base station (hereinafter abbreviated as a base station) is provided for each level, and a group of a plurality of these zones is called a control area, and a radio line control station (hereinafter abbreviated as a control station) is provided. Controlling the station. The control area is within the range of prefectures.

In such a mobile telephone network, a mobile device registers its position information. That is, the position information is registered in the home memory of the exchange through the zone base station and the control station. The mobile station transmits position information when it moves beyond the area, when the power is turned on and when a call is made, and changes the contents of the home memory of the exchange. In this way, the latest position information of the mobile device is stored in the memory.

When connecting to a mobile device from a fixed telephone network,
Through the fixed telephone network, an exchange station in a predetermined area is called, and the home memory refers to the location registration information of the terminating mobile station. If there is a corresponding mobile station, the control station makes a simultaneous call to the area. If it is not registered in the home memory of the exchange, the trace routing is performed to check the home memories of exchanges in other areas, and the connection route is determined. For this automatic tracking, it is necessary to exchange various control signals between the exchanges.

[0005]

However, in the current calling method in the mobile telephone network, the position registration information is sent to the base station even when the user leaves the control area even when no call is being made. That is, it is necessary to always register the latest position, and if it is not registered in the home memory, it is necessary to check the home memory in another area and trace it until the corresponding control area is found. For that purpose, it is necessary to exchange various kinds of information between the exchanges, and the connection processing is extremely complicated, and the control program software therefor becomes enormous and enormous costly.

In addition, the transmission of the position registration information has a problem that power consumption becomes a problem in a mobile phone having a small battery capacity.

In view of the problems of the conventional mobile body calling method, an object of the present invention is to provide a system capable of calling without performing position registration in advance.

[0008]

According to the present invention, in a mobile telephone calling method in a mobile telephone network in which a switching center that controls a plurality of radio base stations is arranged, a call from a caller's telephone received by a communication satellite is performed. A signal regarding the telephone number information of the recipient to be transmitted is transmitted to the ground, and the telephone of the recipient receives the signal regarding the telephone number information from the communication satellite, compares it with its own telephone number, and based on the result, This is a mobile telephone calling method that sends out its own position information signal to the nearest wireless base station.

Further, according to the present invention, the signal relating to the telephone number information of the recipient sent from the above-mentioned telephone of the sender is:
A mobile telephone calling method that is transmitted to the exchange and is sent from the exchange to the communication satellite.

[0010]

In the present invention, the signal of the telephone number information of the receiver, which is transmitted from the telephone of the sender, is sent to the communication satellite via the exchange. The communication satellite transmits the signal to the ground. All the mobile units on the ground receive the signal, and the mobile units of the corresponding receivers send the position information to the nearest base station in the area.
The position information is sent from the mobile telephone network switching center to the fixed telephone network switching center via the control station, for example. The connection route can be determined by this position information.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a mobile body calling method according to an embodiment of the present invention. In FIG. 1, 1 is a communication satellite, 21 is an originator of a fixed telephone network, 22 is a telephone of the originating side, 23 is a fixed telephone network switching center, 13 is a mobile telephone network switching center, and 14 is a control area. Control station,
Reference numerals 15 and 16 are base stations of each zone, 17 is a mobile phone of the receiving side, 18 is a recipient, and 171 is a mobile phone of a recipient of another zone. The operation of such a configuration will be described below.

When the caller 21 who subscribes to the fixed telephone calls the mobile telephone 17 of the receiver, the processes up to the connection are performed in the order described below.

When the caller 21 dials the number of the mobile phone 17 by using the telephone 22 of the fixed telephone network, the telephone number information of the other party is sent to the exchange 23 of the fixed telephone network and provided in the exchange 23. The telephone number information is transmitted from the communication satellite antenna 231 to the communication satellite 1. The communication satellite 1 relays and amplifies the signal of the telephone number information and transmits it to the ground. The mobile phone 17 in the standby state receives this signal and, if it matches the telephone number assigned to itself (mobile phone 17), sends a response signal including position information to the nearest base station 15. If they do not match, ignore them.

The response signal from the corresponding mobile phone 17 is
It is received by the nearest base station 15 and sent to the exchange 13 of the mobile telephone network via the control station 14. The exchange 13 is connected to the exchange 23 of the fixed telephone network. In this way, the location information of the mobile phone 17 of the recipient reaches the exchanges 13 and 23, so that the connection route is determined. When the connection route is set, the exchange 13 calls the mobile phone 17 of the recipient 18 for the first time.

Although the call connection procedure between the fixed telephone network and the mobile telephone network has been described above, the same applies to the call between the mobile telephones 17 in the mobile telephone network. That is, when the number of the other party's mobile phone 171 to be called is dialed with the mobile phone 17, the other party's telephone number information is sent from the mobile phone 17 to the control station 14 via the nearest base station 15 and further to the exchange station 13. . The exchange 13 sends the telephone number information to the communication satellite 1.
The satellite 1 sends out its telephone number information. The mobile phone 171 of the other party receiving the telephone number information from the satellite 1 transmits the response signal including the position information to the nearest base station 1 as described above.
By sending the data to the control station 14, the connection route via the control station 14 and the exchange station 13 is set.

The signal transmitted from the communication satellite 1 is telephone number information of about 10 digits, and since the amount of information can be extremely small, the transmission output from the satellite 1 can be made small. Therefore, the cost of the satellite 1 can be kept lower than that of a satellite that relays high-speed data.

The signal relating to the telephone number information of the receiver, which is transmitted from the telephone of the sender of the present invention, is transmitted from the exchange to the communication satellite in the above embodiment, but the present invention is not limited to this. It may be sent from a station or a dedicated calling station.

Further, the mobile telephone of the present invention may be any device as long as it has a movable telephone function, such as a car telephone, in addition to the mobile telephone as in the above embodiment.

In the above embodiment, there is a control station which controls a plurality of radio base stations and an exchange station which controls the plurality of control stations exists. However, the control station is not limited to such a configuration. The target may be a mobile telephone network or the like having a non-control area.

[0021]

As is apparent from the above description,
According to the present invention, a complicated control such as a memory for location information registration in the exchange and a tracking routing for finding an exchange with which the location information is registered are unnecessary, and the control software cost for this is eliminated. Can be significantly reduced and the system can be simplified.

Further, since it is not necessary to register position information even when moving between areas, the battery consumption of the mobile phone can be prevented, so that the waiting time and continuous call time can be extended.
The practical effect is great.
