Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a location registration method for a mobile radio device moving in a plurality of radio zones.

(Prior art) Conventionally, a wireless zone (or service area)
There is a mobile communication system in which a plurality of fixed wireless devices are arranged so as to partially overlap each other, and communication is performed between a mobile wireless device moving in each wireless zone and a wired telephone line.

FIG. 2 is a system block diagram showing a conventional configuration of this type of mobile communication system, and FIGS. 3 and 4 are position registration sequence diagrams of a mobile radio device.

In FIG. 2, 3a to 3e are mobile wireless devices, 41 to 43 are fixed wireless devices, 51 to 53 are wireless zones, 6a to 6e are wired telephone lines,
Reference numeral 7 is a line control device. Where 3a is 6a and 3b is 6b
, 3c corresponds to 6c, 3d corresponds to 6d, and 3e corresponds to 6e. Reference numerals 51 to 53 denote wireless zones covered by the fixed wireless devices 41 to 43, respectively.

First, the line connection operation will be described. Wired telephone line
When there is an incoming call to 6a, the line controller 7 activates the fixed wireless device 41 in the wireless zone 51 in which the mobile wireless device 3a corresponding to 6a is present, and sends out an incoming call signal. When receiving the incoming call signal, the mobile radio 3a sounds a sounder to notify the user. When the user responds by off-hook, the mobile wireless device 3a returns a response signal to the line control device 7 via the fixed wireless device 41.
The line control device 7 detects this and connects the wired telephone line 6a to the fixed wireless device 41 to enable the call.

On the other hand, when the user sends a call signal from the mobile wireless device 3a to the line control device 7 via the fixed wireless device 41, the line control device 7 connects the wired telephone line 6a and the fixed wireless device 41, and Allows outgoing calls to the telephone network.

By the way, when the line control device 7 sends an incoming call signal to the mobile wireless device 3a via the fixed wireless device 41 when an incoming call is made to the wired telephone line 6a, the location of the mobile wireless device 3a must be changed. It is necessary to know that it is the wireless zone 51.

In order to transmit a call signal from the mobile wireless device 3a to the line control device 7 via the fixed wireless device 41, the mobile wireless device 3a
Needs to know that his / her location is the wireless zone 51.

Therefore, conventionally, the location registration operation of the mobile wireless device is performed as follows. Now, suppose that the mobile wireless device 3a shown in FIG. 2 moves from the wireless zone 53 to the wireless zone 53, as shown in the sequence diagram of FIG. When is pressed, the mobile wireless device 3a transmits a position registration signal A (including a mobile wireless device identification signal). The fixed wireless devices 41 and 42 in the vicinity which have received this send out position registration signals B1 and B2 to the line control device 7. The position registration signals B1 and B2 include an identification signal of the mobile wireless device 3a and a signal indicating the reception level. Therefore, the line control device 7 that has received the position registration signals B1 and B2 from the fixed radios 41 and 42 is, for example, the nearest fixed radio 41 of the mobile radio 3a based on the signal indicating the reception level, and It is determined that the fixed wireless device of is 42.

Next, the line controller 7 sends a registration completion signal C1 to the nearest fixed radio device 41 and a registration end signal D to the nearby fixed radio device 42. The registration completion signal C1 includes the identification signal of the mobile wireless device 3a and the identification signal of the fixed wireless device 42 in the vicinity.

The fixed radio 41 receiving the registration completion signal C1 is a mobile radio.
A registration completion signal E is transmitted to 3a. Registration completion signal E
Includes the identification signal of the mobile wireless device 3a and the identification signals of the nearest fixed wireless device 41 and the nearby fixed wireless device 42.

From such a sequence, it can be understood that the location wireless zone of the mobile wireless device 3a is 51, the nearest fixed wireless device is 41, and the nearby fixed wireless device is 42. This time,
The mobile wireless device 3a notifies the user of the completion of the position registration by an audible sound or a display.

The above is the position registration operation in the manual position registration mode when the manual position registration button is operated in the mobile wireless device, but the wireless zone in which it is located is automatically registered in each mobile wireless device 3a to 3e. An automatic position registration mode is provided, and the position of each mobile wireless device is registered in the same procedure in this mode as well.

That is, the line control device 7 causes the fixed radios 41 to 43 to transmit the position notification signal including the identification signal of each fixed radio to the mobile radios 3a to 3e while shifting the time. On the machine side, its own wireless zone is detected depending on which fixed radio device receives the position notification signal as the position notification signal.

For example, when the mobile wireless device 3a is present at the position shown by the broken line, only the position notification signal of the fixed wireless device 43 is received, so that the mobile wireless device 3a detects that it is present in the wireless zone 53. However, when the mobile wireless device 3a moves to the position shown by the solid line, the position notification signal from the fixed wireless devices 41 and 42 becomes receivable, but the position notification signal from the fixed wireless device 43 becomes unreceivable. Therefore, the mobile wireless device 3a determines that the wireless zone has moved from 53 to 51 or 52, and in order to register this new position in the line control device 7, a position registration update request is automatically sent. Send to.

The sequence in this case is shown in FIG. The difference from FIG. 3 is that the mobile wireless device 3a has already detected the position. The position registration signal A'is the identification signal of the fixed wireless device 41 which is the transmission destination and is the nearest destination, and the fixed wireless device 42 near it
The identification signal of is included. Also, since it is an automatic operation, there is no display of the registration result to the user.

As a result, the line control device 7 can accurately grasp the position of the mobile wireless device even if the procedure position registration operation is neglected.

(Problems to be Solved by the Invention) However, in the above-described position registration operation, since the manual position registration operation and the automatic position registration operation are not synchronized at all, these two operations conflict with each other, and for example, the automatic position registration operation is performed. Immediately after starting the registration operation, a manual position registration request may be generated by operating the manual position registration button.

Therefore, when such a state occurs, conventionally, the manual position registration operation is performed after the end of the automatic position registration operation. However, when the manual location registration operation is substantially put on standby in this way, the notification of the result of the manual location registration is delayed, and at the same time, the occupation time of the wireless line for location registration is increased and the amount of communication traffic that can be processed is increased. There is a problem that is reduced.

An object of the present invention is to provide a location registration method for a mobile wireless device that can notify the user of the result of manual location registration without delay and can prevent a decrease in communication traffic volume.

[Structure of the Invention] (Means for Solving Problems) According to the present invention, when a manual position registration key operation is received from a user between the start and end of the position registration operation in the automatic position registration mode, the automatic operation The above-mentioned object is achieved by being configured to notify the user of the position registration result in the position registration mode as the position registration result in the manual position registration mode.

(Operation) When the user operates the manual location registration key during the automatic location registration operation, the mobile radio notifies the user of the automatic location registration result as the manual location registration result by an audible sound or display. .

(Embodiment) FIG. 1 is a flow chart showing an embodiment of the present invention, in which a mobile radio device starts an automatic position registration operation and, by the time the operation is completed, a manual position registration button is operated to manually position register When the request is received, the manual position registration request flag is set (S10, S11), and then the automatic position registration operation is continued.

Then, after the completion of the automatic position registration operation, it is determined whether or not the manual position registration request flag is set, and when it is set, it is determined whether or not the automatic position registration operation is completed, and the operation is completed. If so, the automatic position registration result is regarded as the manual position registration result, the user is notified by an audible sound or a display, and the operation returns to the standby state (S13, S14, S16).

However, if automatic location registration could not be completed for some reason, the user of the mobile radio is notified of the incomplete manual location registration by an audible sound or display (S13, S1).
Five).

[Effects of the Invention] As described above, in the present invention, when a manual position registration request is generated during the automatic position registration operation, the automatic position registration result is set as the manual position registration result. It is possible to notify the user of the registration result without delay, and it is possible to prevent a decrease in communication traffic volume.
