Abstract

PROBLEM TO BE SOLVED: To realize a mobile communication system that can predict a future in-zone position registration area without pressing wireless resources and temporarily considerably increasing communication traffic in a mobile communication network even when many people simultaneously get on/off a mobile body at a most frequent time, a start station, or a terminal station or the like without the need for provision of a particular relaying device to the mobile body such as a train. SOLUTION: A mobile communication terminal 1 and a mobile body on which a user possessing the terminal 1 gets on, form/release a master slave relation on the basis of information of a designated ticket 7 including all or part of information specifying a date, a departure time, an arrival time, a boarding station, an exit station and the mobile body, and the mobile communication terminal identification information ID. Each mobile communication terminal does not individually inform a position information management device 60 about the forming/release of the master slave relation but an automatic ticket gate 70 to which the designated ticket 7 is inserted informs the device 60 about it.

2. Description of the Related Art As is well known, in a mobile communication service, a position information management device stores the position of each mobile communication terminal so that a mobile communication terminal such as a mobile phone can receive an incoming call. Is common. In particular,
The area for providing the mobile communication service is divided into a plurality of registration areas, and when the mobile communication terminal moves from one registration area to another registration area, a location registration request specifying the registration area after the movement causes the base station device to The data is transmitted from the mobile communication terminal via the mobile communication terminal to the mobile communication network by consuming radio resources.
Then, in response to the position registration request, the registration area of each mobile communication terminal stored in the position information management device is sequentially updated.

However, for example, when a large number of passengers carrying a mobile communication terminal are on a train or the like, a large number of mobile communication terminals move simultaneously with the movement of the train, so that the number of trains increases. When moving from a registration area to another registration area, a location registration request is sent from each of these mobile communication terminals to the mobile communication network via the base station device at the same time, which causes pressure on radio resources and the There is a problem that communication traffic temporarily increases significantly.

As a technique for solving such a problem,
In Japanese Patent Laid-Open No. 11-355835, there is a master-slave relationship between a mobile body such as a train and a mobile communication terminal existing in the space of the mobile body, and a relay device (opposed to the base station) installed in the main mobile body. Disclosed is a mobile communication system in which a transmitter / receiver and a transmitter for position recognition channel) transmit wireless resources to a mobile communication network on behalf of a position registration request of a subordinate mobile communication terminal. In this mobile communication system, the mobile communication terminal existing in the mobile space performs location registration using the relay device as a virtual base station device, and when the mobile body moves from one registration area to another registration area, The relay device transmits a position registration request to the mobile communication network via the base station device. As a result, it is possible to represent the location registration request of the mobile communication terminal existing in the mobile space.

However, in the mobile communication system disclosed in the above publications, the moving body identification information for identifying the moving body transmitted from the relay device installed in the moving body such as a train is moved. The mobile communication terminal recognizes that the master-slave relationship has been formed and canceled with the mobile body when the communication terminal receives or does not receive the information, and the information on this master-slave relationship is transferred by consuming wireless resources. It is designed to notify the communication network. Therefore, for example, assuming a train as a moving body, when many people get on and off the train at the same time during busy times or at the starting station, the terminal station, the terminal station, etc., the formation and cancellation of the master-slave relationship occur all at once. The information regarding the formation and cancellation of the master-slave relationship is simultaneously notified to the position information management device in the mobile communication network via the base station device. Therefore, even if the mobile communication system is used,
The current situation is that the problems of pressure on wireless resources and temporary increase in communication traffic in the mobile communication network have not been fully solved.

Further, in the above mobile communication system,
For example, a mobile communication terminal existing in the vicinity of a mobile body for the purpose of seeing off erroneously received mobile body identification information for identifying the mobile body transmitted from a relay device installed in the mobile body. In the case where there is a change in the presence or absence of reception of the mobile body identification information, such as when the mobile communication terminal repeatedly enters and leaves the mobile body in a short time, the mobile communication terminal and the mobile body are There is a problem that wasteful formation and cancellation of the master-slave relationship is performed, and information regarding the unnecessary formation and cancellation of the master-slave relationship consumes wireless resources and is notified to the mobile communication network.

In order to solve this problem, even when a plurality of mobile communication terminals move at the same time, it is possible to effectively suppress an increase in communication traffic due to location registration of these mobile communication terminals. Communication systems are conceivable. This mobile communication system will be described below. FIG. 7 is a diagram showing an overall configuration of a conventional mobile communication system.

Reference numeral 11 includes an antenna 211a directed to the outside of the mobile unit 2 and performs wireless communication with a base station 3 forming a base station area 4 in which the relay device 21 is located, while heading to the inside of the mobile unit 2. An antenna 211b is provided, and wireless communication is performed with one or more mobile communication terminals 1 housed in the mobile body 2.

The notification information monitoring unit 212 acquires the notification information transmitted from the base station 3 at a predetermined cycle via the signal transmission / reception unit 211 and monitors it. The notification information includes position registration area information for identifying the position registration area. The notification information monitoring unit 212 monitors changes in the position registration area information, and writes new position registration area information in the position information storage unit 213 when there is a change.

For example, in FIG. 7, assuming that the mobile unit 2 moves from the position registration area 5A to the position registration area 5B, the relay device 21 firstly displays the position registration area 5A from the base station 3-1. After receiving the information, the location registration area information indicating the location registration area 5B is received from the base station 3-4. In this case, the notification information monitoring unit 212 detects that the position registration area information has changed, and updates the position registration area information stored in the position information storage unit 213.

Next, the mobile unit notification information management unit 214 outputs the mobile unit identification number to the signal transmission / reception unit 211 at regular intervals, and the mobile unit identification number is transmitted via the signal transmission / reception unit 211 to the mobile communication terminal 1-1. 1-2, ...

Although the details of the method for obtaining the terminal identification number will be described later, the outline thereof is that the relay device 21 notifies the mobile body identification number at a predetermined cycle, and when the mobile communication terminal 1 receives the mobile body identification number, the mobile communication terminal 1 receives the information. The terminal identification number is transmitted to the relay device 21. Therefore, when the mobile communication terminal 1 enters the mobile unit 2, the terminal identification number of the mobile communication terminal 1 is stored in the mobile communication terminal number storage unit 216 by the mobile communication terminal number management unit 215.

The location registration of each mobile communication terminal 1-1, 1-2, ...
1 performs on behalf of each mobile communication terminal 1-1, 1-2, ... That is, for location registration, each mobile communication terminal 1-1, 1-2, ...
Will be subordinate to 1. By the way, when such a subordination relationship is provided, on the mobile communication network NET side, which mobile unit 2
It is necessary to know which mobile communication terminal 1 is subordinate to. However, in the form in which each mobile communication terminal 1 individually notifies the mobile communication network NET to which mobile body the mobile communication terminal 1 belongs, when a large number of people carrying the mobile communication terminal 1 board a train (mobile body 2). Since each mobile communication terminal 1 broadcasts simultaneously, the traffic of the base station 3 increases.

Therefore, in this example, when the mobile unit 2 moves from one location registration area 5 to another location registration area, the location registration of the relay device 21 and the dependent mobile communication terminals 1- The terminal identification numbers 1, 1-2, ... Are notified to the mobile communication network NET. Next, FIG. 9 is a block diagram showing the configuration of the mobile communication terminal 1.

As shown in the figure, each mobile communication terminal 1 (both the mobile communication terminal 1 inside the mobile unit 2 and the mobile communication terminal 1 outside the mobile unit 2) is stored in the position table 632.
The terminal identification number and the mobile body identification number of each mobile body 2 are stored in association with the location registration area information indicating the location registration area in which each mobile communication terminal 1 and each mobile body 2 is located. Therefore, by referring to the location table 632, the location registration area of each mobile communication terminal 1 can be specified.

Next, the operation of the mobile communication system will be described with reference to the drawings. First, a mobile unit 2 having a mobile communication terminal 1
Subordinate to the position information management device 6 from the mobile unit 2.
The operation up to registration to 0 will be described. In this example,
The subordination relationship is registered at the same time as the position registration of the mobile unit 2. Such a series of processes will be referred to as hierarchical position registration. In the following description, the user of the mobile communication terminal 1-1 and the user of the mobile communication terminal 1-2 board the mobile unit 2 located in the base station area 4c (position registration area 5A), and the mobile unit 2 It is assumed that the mobile station moves to the base station area 4d (position registration area 5B). (Formation of Hierarchical Location Registration) FIG. 13 is a sequence diagram showing a forming operation of hierarchical location registration. First, the relay device 21 of the mobile unit 2 broadcasts the mobile unit notification information including the mobile unit identification number at regular intervals (step S1). When the mobile communication terminal 1-1 and the mobile communication terminal 1-2 detect this (steps S2 and S3), the mobile communication terminal 1-1 and the mobile communication terminal 1-2 send a hierarchical position registration request to the relay device 21. Then, each is performed (steps S4 and S5). Each hierarchical position registration request includes the terminal identification number of each mobile communication terminal 1-1, 1-2.

Upon receiving each hierarchical location registration request, the relay device 21 stores each terminal identification number in the mobile communication terminal number storage unit 216, and sends a hierarchical location registration response to the mobile communication terminal 1.
-1 and the mobile communication terminal 1-2 (step S
6, S7). Therefore, each of the mobile communication terminals 1-1 and 1-2, which has received this, knows that the hierarchical location has been registered, that is, that it has been subordinated to the mobile unit 2 (steps S8 and S9). When a location registration area is changed, a general mobile communication terminal itself sends a location registration request to a base station, but a mobile communication terminal in a subordinate state sends a location registration request to the base station. Not done.

After that, when the mobile unit 2 moves from the base station area 4c (position registration area 5A) to the base station area 4d (position registration area 5B), it is included in the base station notification information notified from the base station 3-4. The relay device 21 and the mobile communication terminals 1-1 and 1-2 respectively receive the location registration area information to be provided (step S10). Then, the mobile communication terminal 1-1,
1-2 stores the received position registration area information in the position information storage unit 13. On the other hand, the notification information monitoring unit 212 of the relay device 21 detects that the previous position registration area information and the received position registration area information do not match, and detects that the position registration area has been changed.

After that, the relay device 21 transmits a hierarchical position registration request to the position information management device 60 via the base station 3-4 and the switching center 4-2 (step S11). The hierarchical location registration request includes the terminal identification numbers of the mobile communication terminals 1-1 and 1-2, the mobile body identification number, and the location registration area information. Next, when the location information management device 60 receives the hierarchical location registration request, the control unit 62 associates the terminal identification numbers of the mobile communication terminals 1-1 and 1-2 with the mobile body identification number of the mobile body 2. The mobile object table 631 is registered (step S12). Further, the control unit 62 overwrites the received location registration area information in the location registration area information column corresponding to the terminal identification numbers of the mobile communication terminals 1-1 and 1-2 and the mobile body identification number of the mobile body 2. (Step S13).
With these, the mobile communication terminals 1-1 and 1-2 and the mobile unit 2
The subordinate relationship is registered and the location registration area information is updated. After this, the position information management device 6
0 indicates the hierarchical location registration response to the exchange 4-2 and the base station 3
-4 to the relay device 21 (step S1)
4). (Location registration) Next, the mobile communication terminal 1-1, 1 is attached to the mobile unit 2.
Position registration will be described by taking as an example the case where the mobile unit 2 moves from the base station area 4c (position registration area 5A) to the base station area 4d (position registration area 5B) while -2 is subordinate.

FIG. 14 is a sequence diagram showing the operation of location registration. When the mobile unit 2 enters the location registration area 5B, the relay device 21 and the mobile communication terminals 1-1 and 1-2 each receive the location registration area information included in the base station notification information notified from the base station 3-4. Receive (step S2
1). Then, the mobile communication terminals 1-1 and 1-2 update the stored contents of the position information storage unit 13 with the received position registration area information. On the other hand, the notification information monitoring unit 21 of the relay device 21
2 detects that the previous position registration area information and the received position registration area information do not match, and detects that the position registration area has been changed (step S22).

After that, the relay device 21 transmits a position registration request to the position information management device 60 via the base station 3-4 and the switching center 4-2 (step S23). The location registration request includes the mobile body identification number and location registration area information, but does not include the terminal identification numbers of the mobile communication terminals 1-1 and 1-2. Next, when the position information management device 60 receives the position registration request, the control unit 62 reads the terminal identification number corresponding to the mobile unit identification number by referring to the mobile unit table 631 (step S24). In this case,
The terminal identification numbers of the mobile communication terminals 1-1 and 1-2 will be read out. Next, the received location registration area information is overwritten in the location registration area information column corresponding to the read terminal identification number and moving body identification number (step S2).
5). As a result, the location registration area information of the mobile communication terminals 1-1 and 1-2 and the mobile unit 2 is updated. Then, the location information management device 60 transmits a location registration response to the relay device 21 via the exchange 4-2 and the base station 3-4 (step S26). (Cancellation of Hierarchical Location Registration) Next, cancellation of hierarchical location registration will be described. FIG. 15 is a sequence diagram showing an operation of canceling hierarchical position registration. In this example, it is assumed that the user of the mobile communication terminal 1-1 moves away from the mobile unit 2.

The relay device 21 of the mobile unit 2 reports the mobile unit notification information at regular intervals (step S31).
When the user of the mobile communication terminal 1-1 gets off and leaves the mobile body 2, the mobile communication terminal 1-1 cannot receive the mobile body notification information. The mobile unit notification information monitoring unit 14 of the mobile communication terminal 1-1 measures the time from the reception of a certain mobile unit notification information to the reception of the next mobile unit notification information, and this measurement time is the relay device. When 21 has exceeded a predetermined time, which is longer than the cycle of notifying the mobile body notification information, it is detected that the mobile body 2 has left (step S32).

After this, the mobile communication terminal 1-1 transmits a hierarchical location registration cancellation request to the location information management device 60 via the base station 3-4 and the exchange 4-2 (step S3).
3). The hierarchical location registration cancellation request includes the mobile body identification number of the dependent mobile body 2, the terminal identification number of the mobile communication terminal 1-1, and the current location registration area information. When the location information management device 60 receives the hierarchical location registration cancellation request, the location information management device 60 deletes the terminal identification number corresponding to the mobile body identification number received from the mobile body table 631 and moves to the mobile body 2. The subordinate relationship of the communication terminal 1-1 is canceled (step S34). As a result, the mobile unit 2 moves to another location registration area, so that the mobile communication terminal 1-
The location registration area information of No. 1 will not be updated.

Next, the control unit 62, based on the received terminal identification number and location registration area information, the location table 63.
2 is updated (step S35). Thereafter, the location information management device 60 sends a hierarchical location registration cancellation response to the switching center 4-2.
And to the mobile communication terminal 1-1 via the base station 3-4 (step S36). This allows the mobile communication terminal 1-1 to know that the subordination relationship has been released (step S37).

Next, the location information management device 60 transmits a hierarchical location registration cancellation request including the terminal identification number to the relay device 21 (step S38), and the relay device 21 assigns the terminal identification number to the mobile communication terminal number. It is deleted from the storage unit 216 (step S39), and the hierarchical location registration cancellation response is returned to the location information management device 60 (step S40). This eliminates the inconvenience of permanently storing the terminal identification number of the mobile communication terminal whose dependent relationship has been released in the mobile communication terminal number storage unit 216.
