BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication system including operation management of a traffic machine.
[0002]
[Prior art]
FIG. 25 is a block diagram showing a conventional mobile communication system. In FIG. 25, 1 is an operation management unit for operating a traffic machine, 4 is a traffic machine whose operation is managed by 1, 5 is an operation control unit for the traffic machine, and 6 is a traffic machine driven by the 5 control unit. It is a drive part. Reference numeral 2 denotes a radio line management unit, 7 denotes a radio base station that establishes a radio line connection with 8 mobile terminals, and 8 denotes a radio terminal apparatus. In the case of the conventional operation management system and the mobile communication system, there is no information transmission path between the operation management unit 1 and the line management unit 2 and the operation of the traffic machine and the operation of the mobile communication system are independent. In one operation management unit, the traffic machine is controlled only from information relating to the operation, and in the second line management unit, the mobile communication system is controlled only from the state of the mobile communication system.
[0003]
Furthermore, FIG. 26 is another block diagram showing a conventional in-building mobile communication system. In FIG. 21, 2 is a line management unit of a mobile communication system, 7B to 7D are radio base stations on each floor, 91B to 91D are radio zones constituted by the radio base stations, 37 is an elevator hoistway, and 211 is each floor. A floor 9 is a database for storing the positions of mobile communication users. In the case of the conventional mobile communication system, the configuration of the radio zone is set for each field, and when the user moves from floor to floor, the radio line is reconnected between the radio base stations on each floor. Further, the registration of the position of the mobile terminal 8 or the mobile communication user 11 in the database 9 is performed in units of the existing floor, and is not registered in the elevator.
[0004]
On the other hand, in recent years, in order to cope with the increase in the number of subscribers in mobile communication systems such as car phones and mobile phones, a plurality of base stations are arranged in a service area, and the shortest base stations capable of repeating frequencies are used. A method using the same frequency is used. In this mobile communication system, by reducing the size of the radio zone formed by one base station, it becomes possible to use the radio frequency band more efficiently and accommodate a larger number of subscribers. .
[0005]
A location registration method and a calling method in such a mobile communication system will be described with reference to the block diagram of FIG. If the position registration of the mobile object is performed for each wireless zone 1101, the traffic of the position registration becomes enormous with the movement of the mobile object between the wireless zones 1101. Therefore, a plurality of radio zones are combined into one location registration area 1010 so that traffic for calling the mobile body does not increase so much, and when the mobile body is called, all radios in the location registration area 1010 are A location registration method and a calling method that are called in the zone 1101 are used. In this system, when the mobile body leaves the registered location registration area, it performs location registration and is registered in a new location registration area.
[0006]
[Problems to be solved by the invention]
Since the conventional mobile communication system described with reference to FIGS. 25 and 26 is operated completely independently of the traffic machine as described above, a new wireless line for communication with the mobile communication terminal 8 in the wireless base station 7 is provided.

The moving body is left registered in the position registration area A10. This makes it possible to reduce location registration traffic.
[0073]
A mobile communication system according to another embodiment will be described. The configuration of the mobile communication system is the same as that of the mobile communication system according to the embodiment of the second invention shown in the block diagram of FIG.
[0074]
Next, the operation of the location registration method in the mobile communication system configured as described above will be described. An area in which a large number of moving bodies enter during a short time is set as a non-position registration area 1011 only during the short time. The position registration is not performed on the moving body that has exited each position registration area 1010 and entered the non-position registration area 1011 and remains registered in each position registration area 1010. As a result, even if a large number of moving bodies enter the non-position registration area 1011 in a short time, it is possible to prevent an increase in position registration traffic. After that, the mobile body leaves the non-position registration area 1011. Even when the mobile object returns to the location registration area 1010 where the location is registered again, there is no need to perform new location registration, and an increase in location registration traffic can be prevented.
[0075]
The configuration of the mobile communication system according to the embodiment of the second invention is the same as the configuration of the mobile communication system according to the embodiment of the first invention shown in the block diagram of FIG.
[0076]
Next, the operation of the calling method in the mobile communication system configured as described above will be described. A case where a mobile object whose position is registered in the position registration area A1010 is called will be described.

Change to the narrow call area. The change of the calling area as described above can be performed as necessary until the calling area is configured from only one wireless zone 1101. As a result, the longer the time during which the mobile body stays in one location registration area, the longer the call area for the mobile body is composed of a small number of radio zones. In such a case, it is possible to greatly reduce the call traffic for the mobile body.
[0081]
FIG. 24 is a block diagram showing the configuration of the mobile communication system according to the embodiment of the second invention. The mobile communication system according to this embodiment includes at least one location registration area 1010. As shown in the block diagram of FIG. 2A, the location registration area 1010 is configured to include at least one wireless zone 1101, and the mobile unit in the wireless zone 1101 has the wireless A communication service is provided by the radio base station 1102 forming the zone 1101.
[0082]
Next, the operation of the calling method in the mobile communication system configured as described above will be described. Since the mobile body has left the position registration area B1010 and is registered in the position registration area A1010, the position registration is not performed for a certain period of time and the calling area is not changed for a long time. A case where the calling area for the moving body is changed several times to become the narrow calling area 1010 by the position registration method of the fourth invention will be described. When calling the mobile body, first, the mobile body is called in at least one wireless zone 1101 in the narrow area calling area 1010. Here, in the case where connection cannot be made within a predetermined time period, in at least one or more wireless zones 1101 that are not included in the narrow area calling area 1016 among the wireless zones 1101 in the location registration area A1010, Call the mobile. As a result, it is possible to reduce call traffic for a moving object that remains in one position registration area for a long time.
[0083]
27 (a) and 27 (b) are block diagrams showing the configuration of the mobile communication system according to the third application example of the second invention. The mobile communication system of the present embodiment is configured to include at least one location registration area 1021. The location registration area 1021 is configured to include at least one or more radio zones 1031, and the mobile body 1040 in the radio zone 1031 is received by a radio base station 1035 that forms the radio zone 1031. Communication services are provided.
[0084]
Next, as an example of the call system operation in the mobile communication system configured as described above, the mobile call area is set to the wireless zone 1031 existing at the end of the call of the mobile 1040, and When the mobile unit 1040 does not perform a new location registration and receives a call to the mobile unit 1040, the mobile unit 1040 is called only in the wireless zone 1031. When there is no response from the mobile unit 1040, A method of calling in the wireless zone 1031 in the location registration area 1021 where the mobile body 1040 is registered will be described.
[0085]
Here, the moving body 1040 that leaves the location registration area 1021B and is registered in the location registration area 1021A will be described. After the mobile unit 1040 is registered in the location registration area 1021A, the mobile unit 1040 makes or receives a call, and the mobile unit 1040 makes or receives a call. When it ends when it exists in the wireless zone 1031D in 1021A, the calling area of the mobile unit 1040 is set to the wireless zone 1031D by narrowing the calling area. As the next call, when there is an incoming call to the mobile unit 1040, the mobile unit 1040 is called only in the radio zone 1031D. When the mobile unit 1040 remains in the wireless zone 1031D, an incoming call can be connected to the mobile unit 1040 by the call.
[0086]
When the mobile body 1040 moves from the wireless zone 1031D to another wireless zone 1031D, the wireless zone 1031 other than the wireless zone 1031D in the location registration area 1021A where the mobile body 1040 is registered. Then, the mobile unit 1040 is called. When the mobile body 1040 is moved from the wireless zone 1031D to another wireless zone 1031 by the call, an incoming call can be connected to the mobile body 1040 by the call.
[0087]
With the above operation, when the mobile unit is stationary in one wireless zone and the mobile unit makes or receives a call, the calling area of the mobile unit is only the wireless zone, and all of the location registration areas Call traffic is reduced compared to call schemes that place calls in the wireless zone. Further, when the mobile body moves from the wireless zone to another wireless zone, location registration traffic does not occur, and even in such a case, an incoming call can be made to the mobile body.
[0088]
Further, when the time during which the calling area of the mobile unit 1040 is set in the wireless zone 1031D exceeds a predetermined value due to the narrowing of the calling area during the above operation, the calling area is set to the wireless zone 1031D. It is also possible to set a larger number of wireless zones 1031 including. By such an operation, even when the moving body moves from the wireless zone 1031D to another wireless zone 1031, the call traffic is compared with the method of calling in all the wireless zones 1031 in the location registration area 1021A. It is possible to reduce the delay, and it is possible to prevent the mobile unit 1040 having a high mobility from significantly increasing the delay in connecting the incoming call by performing the call twice.
[0089]
Furthermore, it is possible to narrow the calling area in response to a request from the mobile unit 1040. For example, the mobile unit 1040 measures the mobility of the mobile unit 1040 itself, and if the mobility is equal to or less than a predetermined value, the mobile unit 1040 calls via the radio base station 1035 at the end of the call. Require a narrow area. If the mobility is equal to or greater than a predetermined value, the calling area is not requested to be narrowed. Only the calling area of the mobile that has requested the narrowing of the calling area is narrowed, and the calling area is narrowed to the wireless zone 1031 that exists at the end of the call.
[0090]
As a result, only the calling area of the mobile body with low mobility is narrowed, and the calling area of the mobile body with high mobility remains set as the position registration area, so call traffic for the mobile body with low mobility is reduced. In addition, it is possible to connect the incoming call to the mobile body having a high mobility and to make a call with one call, and it is possible not to increase the delay in connecting the incoming call so much.
[0091]
28 (a) and 28 (b) are block diagrams showing the configuration of a mobile communication system according to an embodiment of the fourth application example of the second invention.
[0092]
The mobile communication system of the present embodiment is configured to include at least one location registration area 1051. The location registration area 1051 includes at least one or more radio zones 1061, and the mobile body 1070 in the radio zone 1061 is received by the radio base station 1065 that forms the no-zone 1061. Communication services are provided.
[0093]
Next, as an example of the call system operation in the mobile communication system configured as described above, the mobile call area includes the wireless zone 1061 existing at the end of the call of the mobile 1070, and the mobile When the mobile body 1070 is set to a narrow area calling area 1055 that is narrower than the location registration area 1051 where the position registration is performed, and the mobile body 1070 does not perform a new location registration, Call only in the narrow area call area 1055, and if there is no response from the mobile body 1070, call it in the wireless zone 1061 in the location registration area 1051 where the mobile body 1070 is registered other than the narrow area call area 1055 The method will be described.
[0094]
Here, the moving body 1070 that has left the location registration area 1051B and is registered in the location registration area 1051A will be described. After the mobile body 1070 is registered in the location registration area 1051A, the mobile body 1070 makes or receives a call, and the mobile body 1070 makes or receives a call, and the mobile body 1070 makes the location registration area. When it ends when it exists in the wireless zone 1061C in 1051A, the calling area of the mobile body 1070 is set to the narrow calling area 1055A by narrowing the calling area. As the next call, when there is an incoming call to the mobile unit 1070, the mobile unit 1070 is called in the wireless zone 1061 in the narrow area calling area 1055A.
[0095]
When the mobile body 1070 remains in the narrow area call area 1055A, an incoming call can be connected to the mobile body 1070 by the call. When the moving body 1070 moves from within the narrow area calling area 1055A to outside the narrow area calling area 1055A, the narrow area within the position registration area 1051A where the position of the moving body 1070 is registered. In the wireless zone 1061 other than the calling area 1055A, the moving body 1070 is called. Even when the mobile body 1070 moves out of the narrow area calling area 1055A by the call, an incoming call can be connected to the mobile body 1070 by the call.
[0096]
In addition, it is possible to further narrow the calling area of the mobile body in which the calling area is narrowed by the above operation and the calling area is set to the narrow calling area 1055. A description will be given of the moving body 1070 whose position is registered in the position registration area 1051A and whose calling area is narrowed to the narrow calling area 1055A.
[0097]
When the mobile unit 1070 makes or receives a call and the call of the mobile unit 1070 ends when the mobile unit 1070 exists in the wireless zone 1061E in the narrow area call area 1055A, the calling area is narrowed. Thus, the calling area of the mobile unit 1070 is set to a narrow area calling area 1055B that includes the wireless zone 1061E and is narrower than the narrow area calling area 1055A.
[0098]
As a next call, when there is an incoming call to the mobile unit 1070, the mobile unit 1070 is called in the wireless zone 1061 in the narrow area calling area 1055B. When the mobile unit 1070 remains in the narrow area call area 1055B, an incoming call can be connected to the mobile unit 1070 by the call. When the mobile body 1070 moves from within the narrow area call area 1055B to outside the narrow area call area 1055B, the narrow area within the position registration area 1051B where the mobile body 1070 is registered In the wireless zone 1061 other than the calling area 1055B, the moving body 1070 is called. Even when the mobile body 1070 moves out of the narrow area call area 1055B by the call, it is possible to connect an incoming call to the mobile body 1070 by the call.
[0099]
With the above operation, when the mobile body stays in a narrow area and the mobile body makes or receives a call, the calling area of the mobile body becomes a narrow area calling area that is narrower than the location registration area. Compared with the paging method for paging in all wireless zones, the paging traffic is reduced and the paging area is not reduced in a short time. There is a high possibility that an incoming call can be connected, and it is possible to prevent a delay during connection of the incoming call from increasing significantly.
[0100]
Further, when the mobile body moves out of the narrow area calling area, no location registration traffic occurs, and even in such a case, the mobile body can be called. Furthermore, the call area of a mobile unit that has a long residence time in a narrow area can be further reduced by narrowing the area each time a call is made.
[0101]
In addition, if the time during which the calling area of the mobile unit 1040 is set as the narrow area calling area 1055 exceeds a predetermined value due to the narrowing of the calling area during the above operation, the calling area is narrowed. It is also possible to set a call area composed of a larger number of wireless zones 1031 than the area call area 1055. By such an operation, even when the mobile body moves out of the narrow area call area 1055, the call traffic is reduced, and the mobile body 1040 having a high mobility is also received by calling twice. It is possible to not increase the delay during call connection very much.
[0102]
Further, it is possible to narrow the calling area in response to a request from the mobile body 1070. For example, the mobile unit 1070 measures the mobility of the mobile unit 1070 itself, and if the mobility is equal to or less than a predetermined value, the mobile unit 1070 calls the radio base station 1065 at the end of the call. Require a narrow area. If the mobility is equal to or greater than a predetermined value, the calling area is not requested to be narrowed. Only the calling area of the mobile body which has requested the narrowing of the calling area is narrowed, and the calling area is narrowed to the narrow calling area including the wireless zone 1061 existing at the end of the call. As a result, only the call area of the mobile body with low mobility is narrowed, and the call area of the mobile body with high mobility remains set as a wide call area, so that the call traffic is reduced and at the same time the call is made. It is possible not to increase the delay of the time.
[0103]
