Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Industrial Application Field) The present invention provides a wireless
The present invention relates to a location registration method.

(Prior Art) In the past, a plurality of fixed wireless stations were arranged so that a part of the wireless zone (or service area) overlapped, and a mobile station A#1 and a wired telephone line were connected to each other within each wireless zone. There is a mobile communication system that performs communication between

FIG. 3 is a system block diagram showing the conventional configuration of this type of mobile communication system, and FIG. 4 is a position registration sequence diagram of a 4I aircraft before movement. In Figure 3, 3a to 3e
18 before moving, 41-43 are fixed wireless, 51-53
is a wireless zone, 6a to 6e are wired telephone lines, and 7 is a line fee t! It is an El device. Here, 3a is 6a and 3b is 6
b, 30 G, t 6 G, 3d corresponds to 6d, and 3e corresponds to 6e, respectively. Also, 51 to 53 are 41
This is a wireless zone covered by ~43 fixed wireless devices.

First, the line connection operation will be explained. wired telephone line 6
When there is an incoming call to a, the line control device 7 activates the fixed radio 41 in the wireless zone 51 where the mobile radio tF 13a corresponding to 6a exists, and causes it to send out an incoming call signal. mobile radio 3
When a receives an incoming call signal, it sounds a sounder to notify the user. When the user responds by off-hook, the mobile vJ mua 3a sends the line control i via the fixed prefix 11141.
A response signal is returned to the Il device 7. The line control device (ii27) detects this and connects the wired line a6a to the fixed station [Ji41], making it possible to talk.

On the other hand, when the user sends a calling signal from the mobile radio device 3a to the line charge tltVtlff7 via the fixed wireless station 41, the line control device 7 connects the wired telephone line 6a and the fixed wireless device 41, and Allows calls to be made to the telephone network.

By the way, in order for the line control 1 device 7 to send an incoming call signal to the mobile radio 13a via the fixed radio 41 when a call arrives on the wired telephone line 6a described above, it is necessary to know the location of the 1li3a before moving. It is necessary to know that it is the wireless zone 51.

Moving again! 71 no 1! In order to send a calling signal from the IF 13a to the line fee ig+ device @7 via the fixed radio device 41, the mobile radio device 3a must be located in the wireless zone 51.
It is necessary to understand that

Therefore, conventionally, the position registration operation of In before movement is performed as follows. Now, if we consider the case where the mobile radio 13a in FIG. 3 moves from the radio zone 53 to the radio zone 51, as shown in the sequence diagram in FIG. 4, the location registration button is pressed in the mobile radio station 3a. Then, the mobile radio 113a transmits a location registration signal A (including a mobile radio identification signal). The nearby fixed wireless devices 41 and 42 that received this send the location registration signal B to the line control device 7.
This location registration signal B, which is sent out, includes a mobile radio i identification signal and a signal representing the reception level.

So, before fixing 1! jl+! ! The line control device 7, which received the location registration signal B from 41.42, determines, for example, 1! before movement, based on the signal representing the reception level. It is determined that the nearest fixed radio device to Jf13a is 41, and the next closest fixed radio device is 42.

Next, the line control device 7 sends a registration completion signal C to the nearest pre-fixed II machine 41 and a registration completion signal C to the nearby pre-fixed AM 42. The registration completion signal C also includes an identification signal of the mobile radio station 3a and an identification signal of the nearby pre-fixed #1I1142.

Upon receiving the registration completion signal C, the pre-fixed atF 141 transmits a registration completion signal E to the mobile wireless LI1 device 3a.

The registration completion signal E also includes the identification signal of the mobile radio t13a, and the identification of the nearest fixed radio device 41 and the nearby fixed radio device 42.

By such a sequence, before fixing a! It can be seen that the wireless zone in which F13a is located is 51, the nearest fixed wireless device is 41, and the nearby fixed wireless device is 42.

(Problem to be solved by the invention) However, under the conventional regulations, if the power is cut off when replacing the battery in a mobile radio, the registration button must be operated each time the power is turned on again, even if the 8vJ is not present. However, there is a problem in that it is not easy to use.

The object of the present invention is to perform 1! before movement when the power is turned on! ! A mobile device that allows you to automatically register the location of the machine without any troublesome operations.
The objective is to provide a method for registering the location of aircraft.

[Structure 1 of the Invention (Means for Solving Problems) The present invention transmits a location registration signal and a mobile radio identification signal at a predetermined time from an LA device before moving, and a fixed radio device that receives the location registration signal. transmits a signal representing its reception level and a mobile radio device identification signal to the line control device, and the line control device determines the R-short fixed radio device as the mobile radio device based on the received signal from the fixed station AM. At the same time, the shortest pre-fixed II device is notified to the mobile radio device via the shortest fixed radio, and this is sent to the mobile radio device.
The above objective is achieved by storing the information in the file m.

(Function) At a predetermined time, such as after a predetermined time has elapsed after the power is turned on, the location registration signal is automatically transmitted once or multiple times at regular or random time intervals.

(Embodiment) FIG. 1 is a circuit diagram showing an embodiment of a location registration activation circuit provided in a mobile radio in order to automatically register the location of a mobile radio. It is composed of 2. This circuit is provided in place of the conventional position registration button, and when the power is turned on, the repetition counter 1 counts the clock signal from the control section (not shown), and every time the count value reaches a predetermined value. Notifying the timing generation circuit 2 that it is time to generate a position registration signal, and supplying a position registration signal generation command from the timing generation circuit 2 to a control section (not shown) at an appropriate timing;
The control unit is configured to automatically generate a location registration signal.

Here, the generation of the location registration signal is appropriately selected between a method of generating the position registration signal once after a certain period of time has elapsed after the power is turned on, and a method of generating the position registration signal multiple times. If it occurs once, the location registration signal is always transmitted when the power is turned on, so that it is always possible to make and receive calls after a certain period of time has passed after the power is turned on. On the other hand, in the case of multiple occurrences, even when the mobile AM moves to another wireless zone, a location registration signal is automatically generated at the new location, so you can always make and receive calls without being aware of the wireless zone. can be left in the state. In this case, if the frequency of occurrence of location registration signals becomes extremely high, radio channels will be occupied unnecessarily, so it is preferable to apply this method to systems that move frequently or systems that are highly important.

Therefore, one method is to allow the user to arbitrarily set the frequency of occurrence using a dial button or the like, thereby making it possible to accommodate various usage patterns.

On the other hand, the timing at which the location registration signal is repeatedly generated can be set either at fixed time intervals or at random time intervals. In the former case, control becomes easier, but registration failure may occur due to collision of location registration signals of multiple mobile wireless devices, so it is necessary to shift the repetition period for each mobile wireless PiIm or to set it at a random time. An effective method is to set the interval.

FIG. 2 is a time chart when position registration signals are generated at fixed time intervals, and to is when the power is turned on, and from t1 to
tn indicates the generation timing of the first to nth position registration signals. Note that it may also be used in combination with manual location registration.

[Effects of the Invention] As explained above, according to the present invention, since a location registration signal is automatically generated when the power is turned on, manual location registration operations are no longer necessary, and the usability of the mobile radio device is improved. effective.
