Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] Radius is 10 for effective use of frequency
A mobile phone system that uses a plurality of wireless base stations with small transmission power limited to about 0 m and repeatedly uses the same frequency is under study. In particular, from the need for diversification of communication, there is a demand for a system capable of receiving a call and establishing a communication system regardless of where a mobile phone terminal is located, regardless of whether it is in an underground mall, indoors, or outdoors. In these systems, when there is a mobile phone terminal outdoors, a method of calling a pager combined with the mobile phone terminal using a paging method for easily realizing the incoming call function has been considered.

[0002] The present invention is directed to a portable telephone terminal which makes a call through a plurality of radio base stations connected to an exchange in a limited area such as a premises or an underground mall, while taking advantage of the paging method as it is. The present invention relates to a method for effectively performing incoming call control.

[0003]

2. Description of the Related Art Conventionally, a method of realizing an incoming call function by calling a mobile phone terminal by using a paging system is performed without knowing exactly where the mobile phone terminal exists (without requiring location registration). It is possible to call, and even in a system using the mobile phone, there is no need for a dedicated exchange, and there is a great advantage that the system is simple and inexpensive. However, mobile phone terminals
If the terminal moves to a place where paging radio waves are not received, such as a campus or underground shopping mall, the terminal cannot be used. Therefore, it was necessary to provide another transmission means so that the radio waves for paging could be received even in the premises or underground shopping malls.

[0004]

As one example, there is a method of providing a relay amplifier for relaying a radio wave for paging at a high frequency, amplifying a high frequency signal received outdoors, and passing the amplified signal through an LCX or the like to retransmit the signal to a building or an underground mall. It has been considered that the use of these LCXs and the like in addition to the radio base station for a mobile phone is not only economically expensive but also inferior in appearance, and has been a serious problem in use.

[0006]

FIG. 1 shows a first specific embodiment of the present invention.
As an example, the wireless base stations 8 to 9 and the telephone 10 are connected to a general public network 11. Of course, in practice, even outdoors, tens of thousands to hundreds of thousands of wireless base stations,
Although the system will be in the millions to tens of millions of telephones, the example of FIG. 1 will be described here for simplicity. Further, the paging transmission station 1 is connected to the public network 11.
2 is also connected. The service area of each of the wireless base stations 8 to 9 has a radius of about 100 m, but the service area of the paging transmitting station 12 has a radius of several km to several tens km, and the receiving station 6 can receive this radio wave. .

Next, the interior of the indoor 7 has the following system.

The private branch exchange 5 connected to the general public network 11 fetches the terminal-unique number received by the receiving station 6, determines whether or not the number is present in the memory 4, and if it is registered, It is called from each of the wireless base stations 1 to 3 in the premises. Regarding the registration of the terminal-specific number in the memory 4, when the terminal enters the indoor 7, it may be automatically written through any of the radio base stations 1 to 3, or the terminal owner may Radio waves may be emitted from the terminal by manual operation, and writing may be performed via any wireless base station. In the example of FIG. 1, the service area of each wireless base station is about 50 to 100 m, and the target mobile phone terminal 13 is in the service area of the wireless base station 1.

[0009] The mobile telephone terminal can receive the service in the radio base stations 8 to 9, but the radio base stations 1 to 3 in the indoor 7 are provided.
But service is available. In the present system, even when it is difficult to know where the mobile phone terminal is, if the mobile phone terminal and the pager receiver are integrally combined, the receiving function can be performed.

When a call is received from the telephone 10 to the portable telephone terminal 13, the first embodiment is as follows. First, the telephone set 10 sends the telephone number of the telephone set 10 and the number unique to the mobile telephone terminal 13 to the paging transmitting station 12 (x ₁ ), and transmits it to the large zone (x ₂ ). If the mobile phone terminal 13 is outdoors together with the pager receiver, it will receive the waves from the paging base station 12 on the spot, but if it is inside the indoor 7 as shown in FIG. Become.

After the receiver 6 receives the wave from the paging base station 12, the result is sent to the private branch exchange 5 (x
₃ ), the private branch exchange 5 checks whether or not the terminal-specific number received by the receiver 6 is registered in the memory 4;
If you are registered, calling a radio wave which the portable telephone terminal from the radio base station 1-3 can receive direct (x _5). here,
If it is clearly stored in the memory 4 that the radio base station is in the service area, the radio base station will call the terminal, and it is not clear which radio base station is in the service area. If this is the case, it will be in the form of a paging call from each base station. When the mobile phone terminal 13 returns a response signal (x ₆ ), the result is transmitted from the wireless base station 1 to the private branch exchange 5.
(X ₇ ), and a reverse connection to the telephone 10 is made (x ₇ ).
₈ ) The call path is set.

In the embodiment shown in FIG. 1, the telephone 10 calls the mobile telephone terminal 13 and then goes on-hook and waits.

FIG. 2 shows a second practical example according to the present invention.
The only difference from the case of FIG. 1 is that a connecting device 14 is added. In this case, the mobile phone 1
When the number unique to the terminal is transmitted to the paging transmitting station 12 so as to call 3, the line is held by the connection device 14 (y ₁ ). The following is the paging transmission station 12
Then, the terminal-specific number is transmitted (y ₂ ), received by the receiver 6, sent to the private branch exchange 5 (y ₃ ), called from the wireless base station (y ₅ ), and a response is received from the mobile phone terminal 13. 1 (y ₆ ), and the operation up to the notification to the private branch exchange (y ₇ ) is the same as that of FIG. 1, except that the private branch exchange 5 sets a line to the connecting device 14 (y ₈ ) and the connecting device 14 Thus, the line from the telephone 10 and the line from the mobile phone terminal 13 are connected, and a call can be made.

In the embodiment of FIG. 2, the telephone 10 calls the mobile telephone terminal 13 and then goes off-hook and waits.

[0015]

As described above, the present invention provides means for calling a mobile phone terminal without requiring location registration on the network side, regardless of whether the mobile phone terminal is indoors or outdoors.
According to the present invention, when a mobile phone terminal receives a service under a wireless base station connected to a private branch exchange, it is not necessary to connect and connect a pager for calling to the mobile phone terminal. Of course, when used indoors or underground, there is no need for a relay amplifier or LCX to retransmit the radio waves for paging other than the wireless base station for mobile phones. That's a quick solution.
