〔Example〕

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

In the PIS2 diagram, 1 is a mobile radio, 2 is a wireless base station, 3 is a line control device, 4 is an exchange fi (local exchange or private branch exchange fi), 5 is a general telephone subscriber, 6 is a subscriber line,
7 is a wireless transmission line connecting the mobile radio device and the wireless base station; 8 is a first wired transmission line connecting the wireless base station and the line control device;
9 is a second wired transmission line connecting the line control device and the exchange; 10 is a storage file provided in the line control device and having a function of storing at least position information of the mobile wireless device; 11;
is a wired telephone W1 connected to the exchange fIIi4 (if 4 is a local exchange, it is a general subscriber telephone; if it is a private branch exchange, it is an extension telephone fi), 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 configured around these wireless base stations.

If a call is made from a mobile mobile phone, mobile mobile phone #Xfi1
forms a wireless transmission path 7 with the nearest wireless base station 2, and connects the regular telephone subscriber 5 and the mobile wireless device 1 via the wireless base station 2, line control device 3, exchange 4, etc. An outgoing call connection is made between the two parties.

Here, when the calling signal from the mobile radio 8!1 is competitively received by multiple radio base stations, the response signals from the radio base station 2 to the calling signal collide, and the mobile radio i receives this response. This may cause inconveniences such as not being able to receive signals. To avoid this, move no # for example! Device 1 sends a calling signal that includes the equipment identification number (wireless base station identification number) of the wireless base station to which it is connected, and the wireless base station side recognizes that the wireless base station identification number included in the received calling signal is its own. A call response signal may be sent only when the identification number of the wireless base and other station matches.

In other words, when a call is made from Mobile Wireless M Iso i, Mobile Wireless Mobile No. If the base station 2's wireless base station identification number 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 radio 1 disables the call connection operation. Sound (busy tone, alarm sound, etc.) or display (LED) to notify the user of completion.

LCD, etc.) is emitted. In this case, the mobile radio device 1 needs to register its location again in order to establish a connection with the nearest radio base station 2.

Generally, if a telephone user makes a call but is unable to connect, they often repeat the call operation again, but by using this series of operations, once the call connection is incomplete, The content of the present invention is to perform location registration at the next off-hook.

That is, when a call is made from the mobile radio 8!1, the mobile radio 1 sends out a calling signal that includes the identification number of the wireless base station to which it is connected, and the nearest wireless base station that received this calling signal 2, if the wireless base station identification number included in the calling signal does not match the identification number of its own wireless base station, the calling connection operation is incomplete, and the mobile radio 1 sends an indication that the calling connection operation is incomplete. Sound (busy tone, alarm sound, etc.) or display (LED.

(by LCD, etc.) is emitted.

Next, the user of the mobile radio device 1 goes on-hook once upon receiving this call connection failure notification sound (or display), and then goes off-hook again. In response to this off-hook, the mobile radio 8
! 11 sends a location registration request signal including its own mobile radio identification number etc. to the radio base station 2. The radio base station 2 that received this signal recognizes that the request signal does not include a radio base station identification number, so this signal is a location registration request signal A (a location registration request signal from a mobile radio to the radio base station). Knowing this, it sends a location registration request signal B (location registration request signal addressed from the radio base station to the line control device) including information such as the reception level of the request signal to the line control device 3.

When the line control device 3 receives location registration request signals B from a plurality of wireless base stations, it compares the reception level information included in these location registration request signals B, and determines whether the wireless communication between the mobile radio fIIi1 and the wireless base station 2 is A radio base station suitable for connection to the transmission path 7 is selected, and the location information of the mobile radio device 1 (consisting of a combination of the identification number of the radio base station and the identification number of the mobile device) is registered in the storage file 10. (If information has already been registered about the mobile radio device 1, that information is updated). After that, the line control device 3 sends a registration completion signal A (registration completion signal from the line control device to the radio base station) containing at least the identification number of the radio base station to the radio base station 2, and then sends to the mobile radio 8!1 a registration completion signal B (a registration completion signal from the radio base station to the mobile radio #!) containing at least the identification number of the radio base station and the mobile radio Mlfi identification number.

If these operations are carried out, next is the mobile radio at that location? j! If a call is made from mobile radio device 1, the identification number of the wireless base station of the connection destination included in the calling signal from mobile radio device 1 (this is the identification number of the wireless base station included in the previous registration completion signal B). Since the identification number (determined based on the number) matches the identification number of the nearest radio base station, the call connection is carried out from the mobile radio via the nearest radio base station.

In addition, after the above location registration operation, if the call is made after moving to another location, and the call connection with the nearest wireless base station is not completed, the above location registration will be performed again by going off-hook. be done.

On the other hand, when a connection is not completed in response to a call originating from a mobile wireless #lta, the mobile wireless #lta is used as a means to send out a signal for performing location registration that is sent from the mobile radio to the wireless base station.
The location registration method according to claim (2) is characterized in that the XfI 11 has an operating section such as a button or switch other than the 77 of the transmitter/receiver, and the series of operations is the same as above. .

As described above, when a call is received from the general telephone subscriber 5 to mobile wireless device #i 1, based on the location registration information of the mobile wireless device stored in the memory file 10 of the line control device, Then, a call is connected to the mobile radio device 1 via the radio base station 2.

〔Effect of the invention〕

As explained above, according to the method of the present invention, the location information of the mobile radio is registered in the storage file of the line control device via the radio base station. There is an advantage that no matter which region you move to, you can connect a regular telephone subscriber to a mobile phone via the wireless base station at your destination.
