FIG. 1 is a diagram showing a configuration of a mobile communication system according to one embodiment of the present invention. The mobile communication system shown in FIG. 1 constitutes, for example, a digital car telephone system. A macro cell system is constituted by macro cell base stations 3 connected to the mobile communication network 1, and fixed mobile stations are connected to the mobile communication network 1. Fixed telephone network 5 which is a communication network
Is connected to a microcell base station 7 and a control device 9 that controls the plurality of microcell base stations 7 to form a microcell system. Here, the macro cell system is typically a public network system provided by a communication carrier, and the micro cell system is typically a personal network system owned by an individual user such as a private network system.

In the present embodiment, the micro cell system is arranged in an underlay with respect to the macro cell system. Here, as an example, a case will be described in which a microcell system is arranged in an underlay with respect to a macrocell system, but the present invention is not limited to a microcell system arranged in an underlay with respect to a macrocell system, This also includes the case where it is not arranged in the underlay.

The underlay will now be described with reference to FIG. Underlay is, as shown in FIG.
For example, there is a case where a system B corresponding to a micro cell system is arranged under the umbrella (in the area) of a system A corresponding to a macro cell system. That is, FIG.
Then, system B is underlaying on system A. On the other hand, in FIG. 2B, since the system B is not under the umbrella of the system A, it means that the system B is not underlaid on the system A. In FIG. 2B, since the system B 'protrudes from the area of the system A by half, the system B' does not underlay the system A.

In FIG. 1, the mobile station 11 which is located in the macro cell system and communicates with the macro cell base station 3 moves and controls the micro cell base station 7 and the plurality of micro cell base stations 7. This indicates that the user is located in the microcell system including the device 9.

In the mobile communication system configured as described above, when the mobile station 11 is no longer permitted to use the cellular system due to, for example, suspension of use or cancellation due to non-payment of the fee, information indicating that such mobile station cannot be used, that is, The communication regulation information needs to be properly notified and linked to the micro cell system from the viewpoint that the micro cell system is an extended part of the macro cell system.

For this reason, in the mobile communication system of the present embodiment, when the above-described unusable situation occurs for the mobile station 11, the macro cell system
The mobile station 1 generates communication restriction information indicating that the mobile station 1 is unavailable.
1 notifies the mobile station 11 of the communication restriction information when the mobile station 1 is located in the macro cell system.

The notification of the communication restriction information to the mobile station 11 can be realized by the following various methods.

(1) Notification is made by adding communication restriction information to a response signal to a position registration request signal from the mobile station 11 to the macro cell, that is, a position registration acceptance signal, a position registration rejection signal, and the like.

More specifically, the location registration sequence between the mobile station and the macrocell base station is performed as shown in FIG.
In the position registration sequence of FIG. 3, while the mobile station is located in the macro cell, a position registration request signal is first sent from the mobile station to the macro cell base station, and then an authentication request signal is sent from the macro cell base station to the mobile station, Next, an authentication response signal is sent from the mobile station to the macrocell base station, and a location registration acceptance signal or a location registration rejection signal containing communication restriction information is sent from the macrocell base station to the mobile station.

(2) After processing the location registration request from the mobile station 11, the macro cell system notifies the mobile station 11 by means of a pseudo incoming call or the like to perform the notification.

More specifically, an incoming sequence between a mobile station and a macrocell base station is performed as shown in FIG. 6, the paging signal is first sent from the macrocell base station to the mobile station, the incoming radio status report signal is sent from the mobile station to the macrocell base station, and then the authentication request signal is sent from the macrocell base station to the mobile station. The authentication response signal is sent from the mobile station to the macro cell base station, and the mobile station release signal including the communication restriction information is sent from the macro cell base station to the mobile station.

When the communication restriction information is included in the mobile station release signal, the mobile station release signal can have a signal format as shown in FIG.

(3) When there is a call request from the mobile station 11, the notification is made by defining the communication restriction information in a signal for notifying the rejection, for example, a mobile station release signal.

More specifically, the transmission sequence between the mobile station and the macrocell base station is performed as shown in FIG. In the transmission sequence shown in FIG. 8, first, an outgoing radio status report signal and a call setup signal are transmitted from the mobile station to the macro cell base station, and a mobile station release signal including communication restriction information is transmitted from the macro cell base station to the mobile station. .

In this case, the mobile station release signal can have a signal format similar to that shown in FIG.

(4) The mobile station 11 is
When the communication restriction of (1) is performed, the macro cell system notifies the mobile station 11 by means of a pseudo incoming call or the like to perform the notification. In this case, since the mobile station 11 may not be able to receive this signal, the macro cell system determines whether or not there is a response from the mobile station 11, and if there is no response, (4-1) Periodic Simulated incoming call to (4-
2) The notification is suspended until the mobile station 11 is located in the macro cell system, and the notification after being located is performed by any one of the above-described methods (1) to (3).

Based on the communication restriction information notified as described above, the mobile station 11 transmits the communication restriction information to the micro cell system when the mobile station 11 is in the communication restriction state and shifts to the micro cell system. It is determined that notification is necessary. This determination can be made by (1) receiving the communication restriction information once by the mobile station 11 or (2)
There is a method of receiving the communication restriction information by receiving the communication restriction information a plurality of times, for example. When the communication restriction release is recognized during the reception of the communication restriction information a plurality of times, the number of signal receptions is cleared to zero.

The notification of the communication restriction information from the mobile station 11 to the micro cell system can be realized by the following method.

(1) Notification is performed by performing notification in a location registration sequence.

More specifically, the location registration sequence between the mobile station and the microcell base station is performed as shown in FIG. In the position registration sequence of FIG. 9, while the mobile station is located in the microcell, first, a position registration request signal including communication restriction information is sent from the mobile station to the microcell base station.
Next, an authentication request signal is sent from the microcell base station to the mobile station, then an authentication response signal is sent from the mobile station to the microcell base station, and a location registration acceptance signal is sent from the microcell base station to the mobile station.

When the communication restriction information is included in the position registration request signal, the position registration request signal can have a signal format as shown in FIG. In FIG. 10, the information elements surrounded by thick lines indicate newly provided information elements.

(2) After the mobile station 11 is located in the micro cell, there is a method of transmitting a call to an existing predetermined special number defined for notification of communication restriction information.

Further, the detection of the communication restriction in the microcell system notified of the communication restriction information from the mobile station 11 is as follows.
There are methods such as (1) detecting communication restriction by receiving the communication restriction information once, and (2) receiving communication restriction information by receiving the communication restriction information a plurality of predetermined times. If communication restriction release is recognized during reception, the number of signal receptions is cleared to zero. In this way, when detecting the communication restriction state of the mobile station 11, the micro cell system restricts the communication of the mobile station 11 in its own area.

Further, the communication regulations for the mobile station 11 are as follows.
There are methods such as (1) prohibiting the presence in the area or (2) permitting the presence in the area, but prohibiting outgoing / incoming calls, which can be arbitrarily set by the business operator.

Next, a communication restriction process in the mobile communication system of the present embodiment will be described with reference to a flowchart shown in FIG.

In FIG. 2, first, the mobile station 11 is located in the macro cell system (step S10), and it is checked whether or not the mobile station 11 has been shifted to the micro cell system (step S11). . If the mobile station 11 is not in the service area, it is detected whether or not there is a communication restriction on the mobile station 11 (step S1).
2). If there is a communication restriction, the communication restriction information is notified to the mobile station 11 as described above, the communication restriction is turned on (step S13), and the process returns to the initial processing.

On the other hand, if it is determined in step S11 that the mobile station 11 is to move to the micro cell system, the mobile station 11
Migrated to the microcell system and stayed (step S
14) It is checked whether or not the mobile station 1 is in the communication restricted state (step S15).
1 notifies the micro cell system of the communication restriction information (step S16), whereby the communication restriction is performed.

More specifically, the communication restriction processing in the mobile communication system according to the present embodiment is realized as follows based on the radio section signal sequence of FIG. 12 (mobile station initiated type) or FIG. 13 (base station initiated type). it can.

In the mobile station-led radio section signal sequence shown in FIG. 12, a location registration request signal is first sent from the mobile station to the macro cell base station while the mobile station is located in the macro cell.
Next, an authentication request signal is sent from the macrocell base station to the mobile station, then an authentication response signal is sent from the mobile station to the macrocell base station, and a location registration acceptance signal or a location registration rejection signal containing communication regulation information is sent to the macrocell base station. To notify the mobile station that communication is being restricted in the macro cell.

Thereafter, while the mobile station is located in the microcell, a location registration request signal is first sent from the mobile station to the microcell base station, and then an authentication request signal is sent from the microcell base station to the mobile station, and then An authentication response signal is sent from the mobile station to the microcell base station, and a location registration acceptance signal is sent from the microcell base station to the mobile station. In response, the micro-cell base station starts restricting communication with the mobile station.

In the base station-initiated radio section signal sequence shown in FIG. 13, while the mobile station is located in the micro cell, first, a location registration request signal is sent from the mobile station to the micro cell base station, and communication is restricted in the macro cell. And report that
Then, an authentication request signal is sent from the microcell base station to the mobile station, an authentication response signal is sent from the mobile station to the microcell base station, and a location registration acceptance signal is sent from the microcell base station to the mobile station. It also instructs to confirm the communication regulation in the macro cell by the position registration acceptance signal.

Thereafter, while the mobile station is located in the macro cell,
First, a location registration request signal is sent from the mobile station to the macrocell base station, then an authentication request signal is sent from the macrocell base station to the mobile station, then an authentication response signal is sent from the mobile station to the macrocell base station, and the communication restriction information Is transmitted from the macro cell base station to the mobile station to notify that the communication is being restricted in the macro cell.

Thereafter, while the mobile station is located in the micro cell, first, a location registration request signal including the communication restriction information is sent from the mobile station to the micro cell base station to report that the communication is being restricted in the macro cell. Then, an authentication request signal is sent from the microcell base station to the mobile station, then an authentication response signal is sent from the mobile station to the microcell base station, and a location registration acceptance signal is sent from the microcell base station to the mobile station. In response, the micro-cell base station starts restricting communication with the mobile station.

In order to perform the above-described communication restriction processing, the mobile station device in the mobile communication system of the present embodiment has an internal configuration as shown in FIG. That is, the mobile station apparatus includes an antenna 111, a radio unit 112 connected to the antenna 111, a control CPU 113 connected to the radio unit 112, a memory 114 connected to the control CPU 113, Unit 112 and control CPU 1
13 and a microphone 116 and a speaker 117 connected to the audio codec.
And the keyboard 11 connected to the control CPU 113
And 8. The radio unit 112 further includes the modulator 11
21, a demodulator 1122, and a channel codec 1123.

The memory 114 has a dedicated memory area 1141 for macro cells, a shared memory area 1142 for macro cells and micro cells, and a dedicated memory area 1143 for micro cells. The macro cell memory area 1141 stores parameters required for macro cell operation, and the micro cell memory area 1143 stores parameters required for micro cell operation. Shared memory area 1
142 stores communication regulation information used in the present invention.

When performing a normal calling / incoming call operation during operation in the macro cell, the mobile station operates using the parameters stored in the macro cell memory area 1141 under the control of the control CPU 113. When the mobile station receives the communication restriction information from the macro cell base station during operation in the macro cell, the mobile station stores the communication restriction information in the shared memory area 1142 under the control of the control CPU 113.

Thereafter, when the mobile station moves and is located in the micro cell, the mobile station reads out the communication regulation information stored in the shared memory area 1142 under the control of the control CPU 113 and transfers it to the micro cell base station. Notify stations.

There are one type of communication restriction information and a plurality of types of communication restriction information. For example, a plurality of types of communication restriction information, such as temporary non-usable information indicating suspension of use and permanent non-usable information indicating cancellation, are described. In this example, two types of communication restriction information are prepared, and thereby, a plurality of types of restriction states in the microcell system can be set. For example, in order to define two types of communication regulation information, a 2-bit signal area is provided and can be defined as follows.

11: Communication restriction (permanent use impossible) 10: Communication restriction (temporary use impossible) 00: No communication restriction When two types of communication restriction information are provided, temporary When it is temporarily unavailable, communication restrictions or temporary communication restrictions may be released later, but when it is not permanently available, these cannot be present. Processing such as notification of communication regulation information to the cell system and recognition of communication regulation in the micro cell system needs to be performed in a different form for each state.

Next, a restriction release notification to the mobile station for releasing the communication restriction set as described above will be described.

When notifying the release of the communication restriction, it is necessary to define a signal meaning "no communication restriction". In the case of two types, with and without communication regulation, a 1-bit signal area is provided and can be defined as follows.

1 ... with communication restriction 0 ... without communication restriction In addition, when there are two types of communication restrictions, that is, permanently unavailable and temporarily unavailable, and when there is no communication restriction, a 2-bit signal area is used. And can be defined as follows:

11: Communication restriction (permanent use impossible) 10: Communication restriction (temporary use impossible) 00: No communication restriction Transmission of communication restriction release signal notifies communication restriction information This method is the same as (1) adding a communication restriction release signal to a response signal to a position registration request signal from a mobile station to a macro cell, that is, a position registration acceptance signal, a position registration rejection signal, or the like, 2) After processing the location registration from the mobile station, the macro cell system notifies the mobile station of the location by means such as pseudo reception, or (3) accepts a call request from the mobile station when it is requested. This can be done by defining communication restriction information in the signal to be notified, or (4) when the cellular system operator releases the communication restriction of the mobile station, the macro cell system can use a pseudo-call termination or the like to perform communication. In addition to performing notification to the mobile station, in this case, the mobile station may not be able to receive this signal, so the macro cell system determines whether or not there is a response from the mobile station, and if there is no response, (4-1) Periodically perform a pseudo incoming call, or (4-2) suspend the notification until the mobile station is located in the macro cell system, and perform the notification after being located in the same manner as the various methods described above. Or go.

Although the communication restriction release signal is normally transmitted in the same method as the communication restriction information notification method, it is also possible to adopt a configuration in which the communication restriction release signal is notified in a different method, which is optional for the operator. .

Further, the notification of the release of the communication restriction from the mobile station to the microcell system is performed, for example, by (1) notifying by a location registration sequence, or (2).
After being in the service area, the notification can be made by sending a call to an existing predetermined special number defined for communication restriction release notification and notifying.

Further, as the detection of the release of the communication restriction, the fact that the mobile station cannot receive or detect the communication restriction information can recognize that the communication restriction has been released.

As described above, the method of detecting the release of the communication restriction by the non-reception of the communication restriction information is based on the method (2) in the above-mentioned processing (1) to (4) for notifying the mobile station of the communication restriction information. After the location registration request is processed, the macro cell system notifies the mobile station by means such as a pseudo call, or (4) a pseudo call when the cellular system operator restricts the communication of the mobile station. In this case, the macro cell system notifies the mobile station from the means, and in this case, the mobile station may not be able to receive this signal. Therefore, the macro cell system determines whether or not there is a response from the mobile station. If not, (4
-1) It can be applied to a case where a pseudo incoming call is periodically performed, or (4-2) a process in which a mobile station makes a pseudo incoming call and notifies after a mobile station is in a macro cell system. That is, the mobile station is notified of the communication restriction information by any one of the notification processes, and is applicable to a case in which a method capable of receiving the communication restriction information is used. The reception timing can be grasped. Therefore, if the communication restriction information cannot be received at this reception timing, it can be determined that the communication restriction has been released.
In this case, it is also possible to arbitrarily set whether to determine that communication restriction is released only when reception is impossible once or to determine that communication restriction is released when continuous reception is impossible a plurality of times.

Further, as the detection of the release of the communication restriction, the release of the communication restriction can be detected because the mobile station can operate normally in the macro cell system. That is, if the communication restriction on the mobile station is released, the mobile station can naturally be used in the macro cell system. Therefore, when the mobile station recognizes that (1) the location registration operation, (2) the calling operation, or (3) the receiving operation is normally performed in the macro cell system, the communication restriction of the mobile station is released. Can be determined. The timing at which the communication restriction release is detected in (1) to (3) is an arbitrary design item of the business operator. For example, (1) communication restriction release due to normal reception of location registration Judgment, (2) it is determined that communication restriction is released when the control sequence of the transmission operation is completed, and the state shifts to the communication state, or (3) it is determined that communication restriction is released when an incoming signal (paging) is received. be able to.

When the mobile station returns to the macro cell system and wants to temporarily release the communication restriction in the micro cell system before detecting the release of the communication restriction, (1) the mobile station operates a command or transmits a predetermined special number. For example, a temporary restriction release request signal is transmitted, and (2) the microcell system that has received the temporary restriction release request signal temporarily releases the communication restriction of the mobile station.

After the communication restriction has been temporarily released as described above, the mobile station shifts to the macro cell system. If the communication restriction has been properly released here, the mobile station is notified by the above-described restriction release notification processing. Restriction release can be detected.
