あり設備投資も非常に高額になるデメリットがあった。However, as a method for registering the location, for that purpose, in addition to the PSTN network, a database for storing the location registration information, a dedicated exchange, etc. are required, and a general telephone to a mobile telephone is required. When making a call to a terminal, it is a procedure to refer to the database once, inquire which base station to connect to the line, and then connect the line by a dedicated exchange.For this reason, not only compressing the wired line, The system was complicated and there was the disadvantage that the capital investment was very expensive.

るため、使い勝手上の不具合も問題になっていた。On the other hand, as an inexpensive method, a method of directly calling a pager terminal connected to a mobile phone terminal from a paging transmission station has been considered. In this case, there are two types of terminals, a mobile phone terminal and a pager terminal. It is necessary to combine them, which is not only disadvantageous in terms of the physical size of the terminal, but also the difficulty of owning the terminal which is uneconomical for the user. Further, in this method, since the service areas of the paging radio wave and the radio wave of the radio base station are different, there is a problem in terms of usability.

A wireless transmission station that covers a large zone transmits a terminal-specific number, and one or more stations among wireless base stations that are connected to a wired line and have a small service area have a terminal-specific number. When receiving the activation signal, the activation signal for receiving an incoming call is transmitted to the terminal having the number unique to the terminal, and the terminal having the number unique to the terminal receives one of the radio base stations when receiving the activation signal. Set up a communication path to a wired line via the station.

As an example, wireless base stations 1 to 6 and a telephone 7 are connected to a general public network 8. Of course, tens of thousands to hundreds of thousands of wireless base stations and millions of telephones are actually available.
Although there are tens of millions of systems, a simple example shown in FIG. 1 will be described here for ease of explanation. Further, a paging transmission station 9 is also connected to the public network 8.
It is assumed that the service areas of the respective radio base stations 1 to 6 each have a radius of several hundred meters or around 100 meters. Also,
The service area of the paging transmitting station 9 has a radius R 9 of several km to several tens of km, and the wireless base stations 1 to 5 exist therein.
【0007】電話機7から携帯電話端末10へ着信をか
けるにあたり、第1の実施例では次のようになる。In the case of making an incoming call from the telephone set 7 to the mobile telephone terminal 10, the following is performed in the first embodiment.

Send to (x 1 ) and send within a large zone of radius R 6 (x

Further, the wireless base stations 1 to 3 selected by the base station selection signal among 5 transmit the telephone number of the telephone 7 and the terminal-specific number by radio waves that can be directly received by the mobile telephone terminal (x 3 ).

無線基地局の全ての場合もある。FIG. 1 shows a case where the intended mobile phone terminal 10 is present in the service area of the radio base station 2. Here, when the mobile phone terminal 10 is called, a response signal is sent to the radio base station 2. At the same time as returning (x 4 ), reverse connection is made from the radio base station 2 to the telephone set 7 (x 5 ) and the speech path is set. In this case, which radio base station calls the mobile phone terminal is selected by the base station selection signal, but as shown in the example, it may be limited to 1 to 3 radio base stations, or the paging transmitting station There may be all radio base stations present in the 9 zones.

トがある。When the mobile phone terminal is called by using all the radio base stations, it is impossible to predict where the mobile phone terminal is. In this case, it is not always necessary to select which radio base station to start up as the base station selection signal. In addition, when a base station selection signal is sent to call a mobile phone terminal from some limited wireless base stations, it is possible to predict to some extent where the mobile phone terminal exists. In this case, there is an advantage that the base station unrelated to the calling of the terminal does not emit unnecessary radio waves.

の要求に応じるかたちとなる。In FIG. 1, for example, there is a method in which expected position information is stored in the memory 10 and this information is included in the base station selection signal. When this method is used, the location information may be accepted and registered by the subscriber in units of municipalities, or may be registered in units of prefectures. In the service area of the paging transmitting station, the request of the subscriber is met.

に、オフフックしたまま待つ事になる。FIG. 2 shows a second embodiment of the present invention. The difference from the case of FIG. 1 is only that a connecting device 12 is added. In this case, when the number unique to the terminal is transmitted to the paging transmitting station 9 so that the telephone 7 calls the mobile telephone terminal 10, the line is held by the connecting device 12 (y 1 ). In the following, the paging transmission station 9 sends a unique number to the mobile phone terminal 11 together with a base station selection signal to each radio base station (y 2 ), and the mobile phone is sent from each radio base station selected by the base station selection signal. It is the same as the case of FIG. 1 until the mobile phone terminal 11 calls the terminal (y 3 ) and the mobile phone terminal 11 returns a response signal to the wireless base station 2 (y 4 ), but thereafter, the wireless base station 2 becomes the connection device 12. For the line connection (y 5 ), the line from the telephone 7 (y
1 ) and the line (y 5 ) that has passed from the mobile phone terminal 11 through the wireless base station 2 are connected, and a call becomes possible. In this case, the telephone set 7 waits off hook when making an incoming call to the mobile telephone terminal 11.
