〔Example〕

FIG. 2 is a diagram showing a system configuration of an embodiment of the present invention,
This corresponds to claim (1) of the present invention.

In FIG. 2, 1 is a mobile wireless device, 2 is a wireless base station, 3
Is a line controller, 4 is an exchange (local exchange or private branch exchange), 5 is a general telephone subscriber, 6 is a subscriber line, 7 is a wireless transmission line connecting a mobile wireless device and a wireless base station, and 8 is a wireless base station. And a line control device for connecting the line control device, 9 is a second wire transmission line for connecting the line control device and the exchange, and 10 is a function of the line control device for storing at least position information of the mobile radio device. 11 is a wired telephone connected to the exchange 4 (general subscriber telephone when 4 is a local exchange, extension telephone when the private branch is exchange), and 12 is a communication network (public telephone network or private telephone network). . A plurality of wireless base stations 2 are arranged, and a service area is formed around these wireless base stations.

When a call is made from the mobile wireless device 1, the mobile wireless device 1 forms a wireless transmission path 7 with the nearest wireless base station 2 and connects the wireless base station 2, the line control device 3, the exchange 4, etc. An outgoing call connection is established between the general telephone subscriber 5 and the mobile wireless device 1 via the route.

Here, when the calling signal from the mobile wireless device 1 is competitively received by a plurality of wireless base stations, the wireless base station 2 for the calling signal is received.
The mobile wireless device 1 cannot receive the response signal due to the collision of the response signals from the mobile wireless device 1. In order to avoid this, for example, the mobile wireless device 1 transmits a calling signal including the device identification number (radio base station identification number) of the wireless base station of the connection destination, and the wireless base station side includes the calling signal in the received calling signal. The call response signal may be transmitted only when the received wireless base station identification number matches its own wireless base station identification number.

That is, when a call is made from the mobile wireless device 1, the mobile wireless device 1 sends a call signal including the wireless base station identification number of the connection destination, but the nearest wireless base station 2 that has received this call signal. If the identification number of the wireless base station included in the calling signal does not match the identification number of its own wireless base station, the call connection operation is incomplete, and the mobile wireless device 1 uses the call connection operation incompletion. A sound (busy tone, alarm sound, etc.) or display (LED, LCD, etc.) to notify the person is emitted.
At this time, the mobile wireless device 1 needs to re-register its position again so that the mobile wireless device 1 can be connected to the nearest wireless base station 2.

Generally, when the user of the telephone cannot make a connection even if he / she makes a call, he / she often repeats the calling operation again. However, if the calling connection is once completed incompletely by using this series of operations, The present invention is directed to the next off-hook position registration.

That is, when a call is made from the mobile wireless device 1, the mobile wireless device 1 sends a call signal including the wireless base station identification number of the connection destination, but the nearest wireless base station 2 that has received this call signal. If the identification number of the wireless base station included in the calling signal does not match the identification number of its own wireless base station, the call connection operation is incomplete, and the mobile wireless device 1 uses the call connection operation incompletion. A sound (busy tone, alarm sound, etc.) or display (LED, LCD, etc.) to notify the person is emitted.

Next, the user of the mobile wireless device 1 receives this calling connection operation incompletion notification sound (or display) and once goes on-hook and then off-hook again. In response to this off-hook, the mobile wireless device 1 sends a position registration request signal including its own mobile wireless device identification number to the wireless base station 2. The wireless base station 2 which received this signal receives this request signal because the wireless base station identification number is not included in the request signal.
(Location registration request signal addressed to the wireless base station from the mobile wireless device)
Position registration request signal B including information such as the reception level of the request signal toward the line control device 3
(Location registration request signal from the wireless base station to the line controller)
Is sent.

When the line control device 3 receives the position registration request signal B from a plurality of radio base stations, the line control device 3 compares the reception level information included in the position registration request signal B, and compares the reception level information between the mobile radio device 1 and the radio base station 2. A wireless base station suitable for connection to the wireless transmission path 7 is selected, and position information of the mobile wireless device 1 (composed of the identification number of the wireless wireless base station and the identification number of the mobile wireless device).
Is registered in the storage file 10 (if the information about the mobile wireless device 1 is already registered, the information is updated). After that, the line control device 3 sends a registration completion signal A (a registration completion signal addressed to the radio base station from the line control device) including at least the identification number of the radio base station to the radio base station 2, and further the radio base station 2 Is a registration completion signal B to the mobile radio 1 including at least the identification number of the radio base station and the mobile radio identification number (a registration completion signal from the radio base station to the mobile radio).
Is sent.

If these operations are performed and the mobile wireless device 1 makes a call next at the location, the connection destination wireless base station identification number (included in the call signal from the mobile wireless device 1 ( This is determined on the basis of the identification number of the radio base station included in the registration completion signal B) matches the identification number of the nearest radio base station. It is executed via the base station.

In addition, after the location registration operation, a call was made after moving to another location, so if the call origination connection with the nearest wireless base station is not completed, the location registration is executed off-hook again. To be done.

On the other hand, a transmitter / receiver hook is used as a means for transmitting a signal for position registration, which is transmitted from the mobile radio device to the radio base station when connection is not completed in response to a call from the mobile radio device. The position registration system according to claim (2) is characterized by having an operation unit such as a button or a switch other than the above, and a series of operations is the same as above.

The call origination has been described above. However, even when the general wireless subscriber 5 receives an incoming call to the mobile wireless device 1, based on the position registration information of the mobile wireless device stored in the storage file 10 of the line control device, A call is connected to the mobile wireless device 1 via the wireless base station 2.

〔The invention's effect〕

As described above, according to the method of the present invention, the location information of the mobile wireless device is registered in the storage file of the line control device via the wireless base station. Even if the user moves to, there is an advantage that the call connection between the general telephone subscriber and the mobile wireless device can be performed via the wireless base station of the moving destination.
