Abstract

PURPOSE:To reduce a position registration traffic by storing a position registration area of a station from which a portable terminal equipment usually gets off to a database and allowing the database to register the portable terminal equipment to a position registration area of a get-off station. CONSTITUTION:Before a portable terminal equipment 110 gets in a train 109, the position is registered in a radio zone 101 and when the terminal equipment 110 enters the train 109, the terminal equipment 10 sends a signal used to inform its own number and position registration to a mobile terminal equipment 114. The terminal equipment 114 sends the position registration of the terminal equipment 110 to a radio base station 105 and a control station 116 receiving it revises the position registration of the terminal equipment 110 in the database 117 from a radio zone 101 to the terminal equipment 114. The terminal equipment 110 stores the position registration area of a station getting off usually to the database in advance and when the terminal equipment 110 reaches the station, the database registers the position of the terminal equipment 110 to a position registration area of the get-off station. Thus, the position registration of the portable terminal equipment is not required and the traffic required for position registration is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a location registration method in mobile communications such as mobile phones.

[0002]

2. Description of the Related Art A user having a mobile terminal (terminal A)
When you move to a new location registration area, location registration is required. However, when moving on a train, etc., many terminals will move to the new location registration area all at once. There arises a problem that registration traffic is generated all at once.

In order to avoid this, a mobile terminal (terminal B) is installed on the train, the mobile terminal is registered to be compatible with the mobile terminal of the train, and when moving to a new location registration area, only the mobile terminal of the train is registered. A representative method is to perform location registration, and the mobile terminal does not perform location registration, so that a method for reducing location registration traffic is considered.

By this method, the position registration traffic when the portable terminals collectively enter the new position registration area is reduced, but when the train arrives at the last station and all users get off at the same time, or get off. In the case of a large station with a large number of mobile terminals, the mobile terminals need to be separated from the mobile terminals of the train, and location registration must be performed simultaneously with the wireless base stations at the station, which causes new bursty traffic. There is.

As a countermeasure against this, when the mobile terminal of the train knows that it has arrived at the last station, it cancels the position registration to the mobile terminal of the train until now, and represents on behalf of the mobile terminal.
A method of registering a location in a location registration area where a new station is located is also considered (Japanese Patent Laid-Open No. 05-55991).

However, this method has a problem that it is not effective unless it is the last station of the train.

[0007]

DISCLOSURE OF THE INVENTION The present invention solves the conventional problems and provides a location registration method for performing location registration on behalf of mobile communication such as a mobile phone and canceling the location registration.
It is an object of the present invention to provide a location registration method that enables efficient location registration even when the train is not at the last station.

[0008]

In order to achieve the above object, the present invention registers, in a database, that a plurality of terminals A correspond to terminal B when a plurality of terminals A move together with terminal B. When terminal A and terminal B move to a new location registration area, only terminal B performs location registration in the database, and when terminal A stops moving together with terminal B, the correspondence with terminal B is canceled and a new location registration area is created. In the location registration method of performing registration in step 1, the “location registration area for releasing the correspondence” between terminal A and terminal B is recorded in advance in one or more databases and terminal A, and terminal B reaches the new location registration area. When the database is notified that the new location registration area has been reached, the location registration of the terminal B is performed in the database and the location registration area is also registered. In the case of "location registration area to release the corresponding" of the terminal A, characterized in that the terminal A releases the correspondence between the terminals A and B registers so as to correspond to the position registration area.

Further, the frequency with which the terminal A cancels the correspondence with the terminal B is recorded for each position registration area, and the "position registration area with which the correspondence is canceled" between the terminals A and B is recorded based on the frequency. The defined mode is effective.

[0010]

Since the present invention has the above-mentioned structure, the mobile terminal records beforehand the location registration area of the station from which it normally gets off, and when the mobile terminal reaches the station,
The database is a method of registering the position of the mobile terminal in the position registration area of the station where the passenger disembarked, without the position registration operation from the mobile terminal.

As a result, when the mobile terminal gets off at the station where the mobile terminal normally gets off, it is not necessary to register the location.
Significant reduction in location registration traffic is obtained.

The effect of the present invention is great because it is considered that there are many cases where the user gets off at the station where he / she is at home, work, or school, such as commuting to work or school.

An embodiment will be described below with reference to the drawings.

[0014]

FIG. 1 is a diagram showing an embodiment of the present invention.
1, 102, 103, 104 are wireless zones, 105, 1
06, 107, and 108 are radio base stations corresponding to the radio zones 101 to 104, 109 is a train, and 110, 1
11, 112, 113 are mobile terminals, 114 is a train 109
Is a mobile terminal, 115 is a train track, 116 is a control station, and 117 is a database.

For simplicity, it is assumed that the location registration is performed in correspondence with the wireless zone.

That is, 101, 102, 103, 10
4 is also a different wireless zone and a location registration area.

From each of the wireless base stations 105, 106, 107 and 108, information indicating their respective location registration areas and wireless zones is constantly or periodically transmitted.

When the portable terminal 113 in the wireless zone 101 receives the radio wave from the wireless base station 105 when it arrives in the wireless zone 101 from another zone, and knows that the new location registration area has been reached, the wireless base station 105 Through control station 1
The location is registered in 16.

The control station 116 stores the number of the mobile terminal 113 and the number of the wireless zone 101 in the database 117.

When the mobile terminal 114 installed in the train 109 is in a new zone, the location registration is performed similarly to the mobile terminal 113.

Further, the mobile terminal 114 sends out a radio wave different from the radio wave from the radio base station 105 into the train 109.

The mobile terminal 113 receives this radio wave at regular intervals, and when it enters the train 109, it receives this radio wave and registers its position in the mobile terminal 114.

In FIG. 1, the position of the mobile terminal 110 is registered in the wireless zone 101 before getting on the train 109.
Upon entering the train 109, the mobile terminal 114 sends a signal indicating that it is its own number and location registration.

The mobile terminal 114 then receives the radio base station 10
In step 5, the fact that the mobile terminal 110 has registered the location with the mobile terminal 114 is transmitted.

Upon receiving this, the control station 116 changes the location registration of the mobile terminal 110 in the database 117 from the existing wireless zone 101 to the mobile terminal 114.

FIG. 2 shows a storage example of the database 117.

In the figure, 201 is location registration data of a mobile terminal installed on a train, and 202 is an example of location registration data of a mobile terminal.

In this example, since the location registration area and the wireless zone have a one-to-one correspondence, the number of the wireless base station is used as the location registration area number.

Since the mobile terminal 114 is in the radio zone 101 in the location registration data 201, the location is registered by the number of the radio base station 105.

In the location registration data 202, the mobile terminal 113 is used.
Is in the wireless zone 101, the location is registered by the number of the wireless base station 105, and the mobile terminals 110, 111, 112 are on the train, so that the location is registered by the number of the mobile terminal 114.

On the other hand, since the mobile terminal 113 is not on the train, the location is registered with the number of the radio base station 105.

The normal entry position registration area of the location registration data 202 is data provided for the present invention, and the number of the position entry area where the mobile terminal normally gets off is recorded.

In the example of the position registration data 202, it is registered that the mobile terminal 110 is usually alighted at the base station 105 and the base station 107.

In the mobile terminal 111, the base station 105 and the base station 108 are normally registered as the getting-off position registration area.

When the train 109 departs and enters the wireless zone 102 along the train track 115, the mobile terminal 114 performs position registration via the wireless base station 106.

The control station 116 stores in the database 117, but the mobile terminal 114 of the position registration data 201 of FIG.
The location registration area of is changed from the radio base station number 105 to 106.

Of course, the mobile terminals 110, 111, 112
Also enters the wireless zone 102, but does not perform location registration.

Since the mobile terminals 110 to 112 are registered in the mobile terminal 114, the location registration need not be performed even if the location registration area is changed, and the location registration traffic is prevented from increasing.

When the train enters the radio zone 103, similarly, only the mobile terminal 114 performs the location registration, and the location registration area of the mobile terminal 114 in the location registration data 201 of FIG. 2 is changed to the number of the radio base station 107. It

Here, it is assumed that the mobile terminals 110 and 112 get off the train.

When the mobile terminal 110 gets off the mobile terminal 114 and receives the radio wave of the radio base station 107, the location registration is normally performed through the radio base station 107. Is registered as the getting-off position registration area, the position is not registered.

Of course, since the mobile terminal 110 records the number of the area where the user gets off the vehicle in the database 117 registered in the mobile terminal, it is easy to know whether the area where the user got off is the registered area. .

When the data of the location registration area of the mobile terminal 114 of the location registration data 201 is changed to the number of the wireless base station 107 due to the location registration of the mobile terminal 114, the database 117 indicates that the data of the location registration data 202 is the alighting location registration area. Of the mobile terminal which is the wireless base station 107.

In the location registration data 202, the mobile terminal 11
The data of the getting-off position registration area of 0 is the wireless base station 107.
The location registration area number of the mobile terminal 110 is changed from the current mobile terminal 114 number to the radio base station 10
Change to number 7.

That is, when the portable terminal gets off in the getting-off location registration area registered in advance, the location registration area is rewritten without sending a location registration signal from the portable terminal.

In order to easily index the number of the mobile terminal registered as the location registration area where the user normally gets off from the number of the location registration area, the mobile terminal uses the mobile terminal 114.
When the location registration is done on the mobile terminal, the location registration area where the mobile terminal normally gets off is extracted, and a database is created that can index the number of the mobile terminal registered there from the number of the location registration area where the mobile terminal usually gets off. It is desirable to keep.

On the other hand, since the portable terminal 112 has not registered the getting-off position registration area, when getting off from the mobile terminal 114 and receiving the radio wave from the radio base station 107, the control station 116 passes through the radio base station 107. Register the location in.

The control station 116 changes the location registration area data of the mobile terminal 112 in the database 117 from the current mobile terminal 114 number to the radio base station 107 number.

In the location registration data 202, the mobile terminal 11
Similarly to mobile terminal 110, No. 1 has the numbers of radio base stations 105 and 108 registered as the alighting position registration areas.

Therefore, in the database 117, the location registration area of the mobile terminal 111 is set as the mobile terminal 11 assuming that the mobile terminal 111 also got off in the area of the radio base station 107.
The number 4 is changed to the number of the wireless base station 107.

However, the portable terminal 111 is the wireless base station 1
Although it came to 07, it did not get off and continued to maintain correspondence with the mobile terminal 114.

In such a case, it is necessary to newly register the location on the mobile terminal 114 from the mobile terminal 111.

In order to know whether or not the mobile terminal 111 has arrived in the new location registration area while on the train, the mobile terminal 114 has all mobile terminals that have boarded the arrival of the new location registration area. There is a method of notifying, or a method in which the mobile terminal periodically receives the radio wave from each wireless base station and searches by itself for arrival in a new location registration zone.

When the train arrives at the location registration area 108 and the portable terminal 111 gets off, of course, the wireless base station 1
The location registration will be performed from 08.

In this way, the position registration area in which the mobile terminal normally gets off is registered in advance, and when getting off in the registered area, the position registration area of the mobile terminal that got off is rewritten without sending a position registration signal. Registration traffic can be reduced.

On the other hand, if the mobile terminal does not get off at the station in the location registration area registered in advance, the location registration will be re-registered to the mobile terminal of the train whose location has been registered so far, and the location registration traffic will be changed. Although it is increased, not getting off in the location registration area where the vehicle normally gets off is considered to occur extremely rarely, and the effect of reducing the location registration traffic by this method is not impaired.

FIG. 3 shows an example of the control flow of the control station and the database of the present invention, and FIG. 4 shows an example of the control flow of the portable terminal.

Next, a method of registering the location registration area where the mobile terminal normally gets off will be described.

The simplest method is a method in which the service subscriber dials a specific number from the mobile terminal to connect to the database, and registers the number of the area where the service subscriber normally considers the location registration area. .

For example, in the case of a location registration area number of a station where one's own house is located or a station area number of a location registration area where a company is located, it is possible to easily determine and register as the location registration area where the user normally gets off.

However, it is troublesome to register the location registration area where the user normally gets off when commuting to work or school is changed, and without registering again,
Since there is no problem in using the mobile terminal, it is considered that there may be cases where re-registration is not performed.

In order to deal with such a case, there may be a method of counting the location registration area of the station where the passenger disembarked with the mobile terminal and automatically registering the location registration area of the station where the disembarking was performed a certain number of times. .

That is, the portable terminal stores the number of the position registration area where the passenger gets off, and adds the value every time he gets off.

In this way, when the added value exceeds a certain value, the mobile terminal automatically registers the location registration area in the database as the location registration area for getting off normally.

Further, even when the user does not disembark in the area registered as the position registration area where he / she normally gets off, if the number of times is added up and the value exceeds a certain value, a signal for canceling the registration of the position registration area where he / she normally gets off is given. The number of the previously registered location registration area is automatically transmitted from the mobile terminal and deleted from the database.

By doing so, the service subscriber can automatically carry out registration and cancellation without being aware of the location registration area where he / she normally gets off.

FIG. 5 shows an example of a control flow of automatic registration and cancellation of the normal getting-off position registration area on the portable terminal.

[0068]

As described above, according to the present invention, when an individual carries a train like a mobile phone and gets on a train, the train is concentrated when a lot of mobile terminals get off at the station all at once. It is possible to reduce the location registration traffic that occurs in.
