Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service regulation control system in a mobile communication system for regulating service provision to an illegally used mobile device which is not properly registered as a subscriber.

[0002]

2. Description of the Related Art In recent years, various mobile communication systems have been operated by a plurality of communication businesses, and many mobile terminals such as in-vehicle type and portable type (hereinafter, simply referred to as "mobile devices") are provided with communication services such as telephone. It is provided. In addition, the sales of such mobile devices have already been liberalized and the number of operating units has increased significantly.According to the increase, the mobile devices are purchased and transmitted before the regular registration procedure as a subscriber is completed. Or
There is an increasing number of illegally used mobile stations that intentionally rewrite the subscriber number MSN and the like for transmission.

FIG. 10 is a diagram showing a configuration example of a mobile communication system. In the figure, a mobile device 71 is located in a radio zone formed by a base station 72, and the base station 72
Is connected to the exchange 74 via the wireless controller 73.
The exchange 74 is connected to a home location register (hereinafter, simply referred to as “HLR”) 75.

In the mobile communication system having such a configuration,
The base station 72 forms a wireless zone under the line setting control performed by the wireless control device 73, and interfaces with a wired transmission path individually corresponding to all the wireless channels assigned to the wireless zone. The wireless controller 73
Of these wireless channels, on a specific wireless channel (for example, the control channel allocated for control),
Monitor the control signals received from the mobile. Further, when the wireless control device 73 recognizes that the location registration request or the call origination request is received from the mobile device in the corresponding wireless zone based on the content of the control signal, the communication control adapted to these requests is performed. Is started, and the interface between the exchange 74 and the base station 72 is established under the communication control.

The exchange 74 receives a call (including a location registration call in addition to an outgoing call and an incoming call) that has occurred to all the mobile stations in the wireless zone formed by the base station 72 via such an interface. , Perform call processing.

[0006] The HLR 75 stores the subscriber number MSN and the authentication information KEY, which are individually assigned, in association with each other for all the mobile stations that are properly registered as subscribers belonging to the service area corresponding to the HLR. .

Assuming that the mobile device 71 is an illegally used mobile device, the mobile device 71 moves into the wireless zone formed by the base station 72 or is powered on in the wireless zone. Then, it recognizes that it has entered the corresponding wireless zone based on a predetermined procedure. Further, the mobile device 71 captures the above-mentioned specific radio channel and transmits a location registration request including the subscriber number MSN of the local station and the mobile device number MSI to the base station 72 (FIG. 11).
(1)).

The base station 72 receives and demodulates such a position registration request (FIG. 11 (2)). The wireless controller 73
The demodulated signal obtained by such demodulation is taken in to restore the subscriber number MSN and the mobile station number MSI, hold the mobile station number, and give the subscriber number MSN to the exchange 74 (see FIG. )).

The exchange 74 uses such a subscriber number MS
When N is given, a random number RN is generated based on a predetermined algorithm and the random number is given to the wireless control device 73 (FIG. 11 (4)). The radio controller 73 transmits the random number RN to the mobile device 71 via the base station 72 (FIG. 11).
(Five)).

Upon receiving such a random number, the mobile device 71 receives the random number and the authentication information key stored in advance in the device.
Then, an authentication response R ₁ is generated by performing a calculation based on a predetermined algorithm (FIG. 11 (6)) and transmitted to the base station 72 (FIG. 11 (7)). The base station 72 receives and demodulates such an authentication response R ₁ (FIG. 11 (8)), and the wireless controller 7
3 captures the result and gives it to the exchange 74 (FIG. 11).
(9)).

On the other hand, the exchange 74 is the mobile station 7
1. In parallel with the cooperative operation of the base station 72 and the wireless control device 73, the subscriber number MSN given by the wireless control device 73 is designated and an authentication information request is issued to the HLR 75 (FIG. 11 (10)). Retrieves and outputs the authentication information KEY corresponding to the subscriber number (FIG. 11 (11)).
The exchange 74 performs an operation based on a predetermined algorithm (which is the same as that applied to the mobile station 71) based on the authentication information KEY and the random number RN described above, and the authentication response information R ₂ Is generated (FIG. 11 (12)).

The exchange 74 receives such authentication response information R
₂ and the authentication response information R ₁ generated by the mobile device 71 as described above are fetched and compared. However, since the mobile device 71 is an illegally used mobile device as described above, the authentication information key is different from the authentication information KEY given from the HLR 75, and these authentication responses do not match. Switch 7
When recognizing that the authentication responses do not match each other in this way, 4 sends a location registration refusal notification to mobile device 71 via radio control device 73 and base station 72 in the same manner as random number RN described above (see FIG. 13)), the wireless controller 73 and the mobile device 71 recognize the location registration refusal notification and interrupt the location registration operation (FIGS. 11 (14) and (15)).

Further, as long as the mobile station 71 is located within the radio zone formed by the base station 72, the mobile station 71 again issues a location registration request to the base station based on a predetermined control sequence. In response to such a location registration request, the base station 72, the wireless control device 73, the exchange 74 and the HLR 7
5 repeats the same operation as the above-mentioned operation (FIGS. 11 (1) to (15)) as shown in FIGS. 11 (1 ') to (15'). Therefore, the description of such operation is omitted here.

[0014]

By the way, in such a conventional mobile communication system, it is not restricted that the illegally used mobile station repeatedly issues the location registration request, and the base station 72, the radio controller 73, Switch 74 and HLR75
11 has repeated the same operation ((1 ') to (15') in FIG. 11 in response to the position registration request repeatedly issued in this manner.

Therefore, in the base station 72, the wireless channel is unnecessarily captured by the illegally used mobile device, and the invalid communication control process and the call process are repeatedly activated in the wireless line control device 73 and the exchange 74.

In addition, the generation of such invalid traffic is a factor that puts a heavy burden on the processing amount of the radio network controller 73 and the exchange 74, especially during the busiest hours, and significantly deteriorates the quality of service to the legitimate mobile unit. Was becoming.

Furthermore, such invalid traffic is not limited to location registration, but similarly occurs, for example, by an outgoing call or an incoming call that repeatedly occurs for an illegally used mobile station, and the probability of occurrence is the same. The number increases as the number of illegally used mobile devices located in the wireless zone increases. Therefore, under the present circumstances, it is expected that the number of illegally used mobile devices will increase in accordance with the liberalization of the sales of mobile devices, and there is a strong demand for prompt and efficient improvement measures.

According to the present invention, the resources allocated to the access of the illegally used mobile device are significantly reduced, and further, such access can be efficiently suppressed and the existence of the illegally used mobile device can be surely grasped. It is intended to provide a service regulation control system.

[0037]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 3 is a diagram showing an embodiment corresponding to the invention described in claims 1 to 6.

In the figure, the difference from the conventional example shown in FIG. 10 is that the wireless control device 73 is replaced by the wireless control device 41, the exchange 74 is replaced by the exchange 42, and the exchange 42 is replaced by the printer 43. It is at the connected point.

Regarding the correspondence between this embodiment and the block diagrams shown in FIGS. 1 and 2, the exchanges 42 and H
The LR 75 corresponds to the exchanging means 11, the judging means 13, the unauthorized mobile device registration means 21 and the control means 23, the base station 72 and the wireless control device 41 correspond to the wireless interface means 12, and the wireless control device 41 registers the unauthorized mobile device. The exchange 42 corresponds to the message generation means 31 and corresponds to the means 14 and the control means 15.

FIG. 4 is a diagram for explaining the operation of this embodiment corresponding to the invention described in claims 1, 5, and 6. Figure 5
7 is an operation flowchart of the radio control device according to the inventions of claims 1, 5, and 6.

The operation corresponding to claim 1 of this embodiment will be described below with reference to FIGS. In the wireless control device 41, an unauthorized mobile device registration table (hereinafter simply referred to as “table”) in which an unauthorized mobile device number for identifying an unauthorized mobile device that has issued a location registration request or a call request described later should be registered in a lump. ) 61 _O and a pointer (WP) 62 _O indicating the writing destination of the table are storage media that can be referred to by software that realizes communication control between the base station 72 and the exchange 42 (for example, main storage or It is provided in advance in the auxiliary memory).

When the mobile station 71, which is an illegally used mobile station, recognizes that it has entered the radio zone formed by the base station 72, it captures a specific radio channel in the same manner as in the conventional example and joins its own station. A location registration request including the personal number MSN and the mobile unit number MSI is transmitted to the base station 72 (FIG. 4).
(1)).

Base station 72, radio control unit 41, exchange 4
2 and HLR75, as shown in FIGS. 4 (2) to (12),
The same operation as that of the conventional example (FIGS. 11 (2) to (12)) is performed. Therefore, description of these operations is omitted here.

Further, the exchange 74 compares the authentication response information R ₂ obtained in the exchange with the authentication response information R ₁ generated by the mobile device 71 in the same manner as in the conventional example, and the two do not match. When recognizing that, the wireless controller 4
1 sends a location registration refusal notification to the mobile device 71 ((1
3)).

Upon recognizing such a location registration refusal notification (FIG. 5 (1)), the radio controller 41 precedes the exchange 42.
The mobile station number MSI held when the subscriber number MSN is sent to the terminal (FIG. 4 (3)) is read out. Furthermore, the wireless controller 4
1 confirms that such a mobile device number is not registered in the table 61 _O , and stores the mobile device number in the area of the table 61 indicated by the pointer 62 _O (see FIG. 5).
(2)) The value of the pointer 62 _O is incremented, and a corresponding location registration request rejection notification is transmitted to the mobile device 71 via the base station 72 ((14) in FIG. 4).

When the mobile station 71 receives and recognizes such a location registration refusal notification, it suspends the location registration operation (FIG. 4 (15)), but is located within the wireless zone formed by the base station 72. As long as it is, the location registration request (including the subscriber number MSN and the mobile station number MSI of the own station) is issued again to the base station based on a predetermined control sequence (FIG. 4 (1 ')).

The base station 72 receives and demodulates such a position registration request (FIG. 4 (2 ')). The wireless controller 41
The demodulated signal obtained by such demodulation is taken in to restore the subscriber number MSN and the mobile station number MSI (see FIG. 5).
(3)), and it is determined whether or not the mobile device number MSI is registered in the table 61 _O (FIG. 4 (16), FIG. 5 (4)).

When the radio controller 41 recognizes that the corresponding mobile station number is not registered by such a determination, it is determined that the location registration request is received for the first time in cooperation with the exchange 42 and the HLR 75. Similar processing is continued.

However, if the opposite is registered,
Since the corresponding mobile device is an unauthorized mobile device, the wireless control device 41 sends a location registration refusal notification to the mobile device 71 via the wireless station 72 instead of the exchange 74 (FIG. 4 (17),
Figure 5 (5)).

Accordingly, the second and subsequent attempts of position registration repeated by the mobile device 71 which is an unauthorized mobile device are promptly rejected by the judgment of the wireless control device 41. It is avoided that the exchange 42 and the HLR 75 perform unnecessary processing for the location registration attempt.

FIG. 7 is a diagram for explaining the operation of this embodiment corresponding to the invention described in claims 2-6. FIG. 8 is an operation flow chart of the exchange according to the invention described in claims 2 to 6.

The operation corresponding to the invention described in claim 2 of the present embodiment will be described below with reference to FIGS. 3 and 6 to 8.
In the exchange 42, an unauthorized mobile device registration table (hereinafter, simply referred to as a “table”) 6 in which an unauthorized mobile device number for identifying an unauthorized mobile device as a destination of an incoming call is to be registered in a lump 6
1 _T and a pointer (W
P) 62 _T is provided in advance in a storage medium (for example, main storage or auxiliary storage) that can be referred to by software interposed between the wireless control device 41 and the HLR 75. When an incoming call to the mobile station 71, which is an illegally used mobile station, occurs, the exchange 42 obtains the subscriber number MSN of the mobile station based on a predetermined call processing procedure, and designates the subscriber number to the HLR 75. An incoming call information request for requesting the authentication information and the mobile station number MSI of the corresponding mobile station is issued (FIG. 7, FIG. 8 (1)). When the HLR 75 recognizes such an incoming call information request, the subscriber number MSN included in the request is received.
The incoming call information including the authentication information KEY corresponding to and the mobile station number MSI is transmitted (FIG. 7).

Further, the exchange 42 holds the authentication information KEY contained in such incoming information and sends out a paging request for designating the mobile unit number MSI as a destination (FIG. 7, FIG. 8 (2)). ). The wireless control device 41 transmits the paging request to the mobile device 71 via the base station 72.

When the mobile station 71 receives and recognizes such a general call, it sends a call response including the subscriber number MSN of the local station and the mobile station number MSI to the base station 72 (FIG. 7)). . The base station 72 receives such a call response and notifies the exchange 42 via the radio controller 41.

When the exchange 42 recognizes such a call response, it generates a random number RN based on a predetermined algorithm, and transmits the random number to the mobile station 71 via the radio controller 41 and the base station 72. (Fig. 7 (4),
(Five)).

Upon receipt of such a random number, the mobile device 71 receives the random number and the authentication information key stored in advance in the device.
Then, an authentication response R ₁ is generated by performing a calculation based on a predetermined algorithm (FIG. 7 (6)) and is transmitted to the base station 72 (FIG. 7 (7)). The base station 72 receives such an authentication response R ₁ (FIG. 7 (8)) and gives it to the exchange 42 via the wireless control device 41 (FIG. 7 (9)).

On the other hand, the exchange 42 is the mobile station 7
1. In parallel with the cooperative operation of the base station 72 and the wireless control device 41, an algorithm predetermined based on the authentication information KEY held in advance and the random number RN described above (to be applied by the mobile device 71) The same) is performed to generate the authentication response R ₂ (FIG. 7).

Further, the exchange 42 fetches and compares the authentication response R ₂ and the authentication response R ₁ generated by the mobile device 71 as described above (FIG. 8 (3)), and the two do not match. When recognizing this, a forced disconnection request is sent to the mobile device 71 via the wireless control device 41 and the base station 72 (FIG. 7, FIG. 8 (4)).

Further, the exchange 42 reads the mobile unit number MSI held in advance and confirms that the same mobile unit number is not registered in the table 61 _T (FIG. 8 (5)).
Then, the mobile station number is stored in the area of the table 61 _T indicated by the pointer 62 _T (FIG. 7, FIG. 8 (6)), and the value of the pointer is incremented.

When the mobile station 71 receives and recognizes the above-mentioned forced disconnection request, it interrupts the incoming call response process (FIG. 7).
. However, such an incoming call to a fraudulently used mobile station is repeatedly generated due to an erroneous setting of the caller's dial number. Especially, the erroneous setting is not recognized by the caller or many people who can be the caller. In many cases, a dial number corresponding to an illegally used mobile device is erroneously transmitted.

In such a case, the exchange 42 requests and acquires the incoming call information by the same procedure as the first incoming call that has occurred for the same illegally used mobile device (FIG. 7'.about.
′). Further, the exchange 42 extracts the mobile unit number MSI included in such incoming information and determines whether or not the mobile unit number is registered in the table 61 _T (FIG. 8).
(7)) When recognizing that it is not registered, the normal incoming call process is continued in cooperation with the radio controller 41 and the base station 72. Note that the procedure of such a normal incoming call process is not directly related to the present invention, and therefore its description is omitted here.

However, if the opposite is registered,
Since the corresponding mobile unit is an illegally used mobile unit, the exchange 4
2 sends a message to the caller to the effect that "the service is not provided because it is an illegal mobile device" for a certain period of time, and further performs disconnection processing based on a predetermined procedure (see FIG. 8 ( 8)) Call processing is completed (Fig. 7).

Therefore, when an incoming call to the illegally used mobile station repeatedly occurs, the radio control device 41, the base station 72 and the radio channel formed by the base station become useless by the second and subsequent incoming calls. The capture is avoided and the call processing of the exchange 42 is interrupted promptly.

The operation of this embodiment corresponding to the inventions of claims 3 and 4 when an incoming call occurs in the mobile device 71 will be described below. When an incoming call is first made to the mobile device 71, which is an illegally used mobile device, the exchange 42 sends a forced disconnection request to the mobile device 71 (FIG. 7, FIG. 8 (5)) in advance. Based on the procedure described above, the mobile station 71 is operated in cooperation with the wireless control device 41 and the base station 72.
A wireless channel for communication is assigned to (Fig. 7 (a)). Further, the exchange 42 sets the communication path by switching the originator of the corresponding incoming call from the actual originator to a message trunk (not shown) that outputs a message described later (FIG. 7 (b)). Further, the switching equipment 42 terminates the transmission of the message at a predetermined time and outputs the above-mentioned forced disconnection request, and thereafter registers the mobile equipment number MSI of the mobile equipment 71 in the table 61 _T (FIG. 7) for call processing. To complete.

The message trunk described above always says "Because the registration procedure as a regular subscriber has not been performed,
A message indicating that the service cannot be provided to the corresponding mobile device is output and transmitted to the mobile device 71 via the above-described communication path and wireless channel (FIG. 7 (c)).

Therefore, the operator of the mobile device 71 is alerted to the effect that "the registration procedure is necessary" by such a message, and the registration procedure is prompted (FIG. 7 (d)).

The operation of the present embodiment corresponding to the inventions of claims 3 and 4 when the outgoing call originates in the mobile device 71 will be described below. The mobile device 71 uses the subscriber number M of the mobile device in accordance with the operation performed by the operator when making a call.
Send a call origination request containing the SN and mobile number MSI. The configuration of such a transmission request is the same as the configuration of the location registration request described above, and the base station 72 and the radio controller 4 are
1, the exchange 42 and the HLR 75 respond to the call origination request by the same procedure as shown in FIGS. 4 (1) to (12) (FIGS. 9 (1) to (1)
Authenticate based on 2)). Therefore, regarding the procedure of such authentication, the same numbers (1) to (12) as those in FIG. 4 are shown in FIG.
Is added and shown, and the description thereof is omitted here.

As a result of such authentication, the exchange 42 recognizes that the source mobile station 71 is an illegally used mobile station, and then performs the wireless transmission based on the same procedure as shown in FIGS. 7 (a) and 7 (b). The channel is set (Fig. 9 (a)). In addition, the exchange 42
Switches the caller from an actual caller to a message trunk (not shown) and sets a speech path for a predetermined time (FIG. 9 (b)), and then sends a forced disconnection request to the mobile station 71. The mobile device number MSI is registered in the table 61 _T as an illegally used mobile device to complete the call processing ((13) in FIG. 9). The message trunk described above always indicates that "registration procedure as an authorized subscriber has not been performed. Therefore, a message that the outgoing call of the corresponding mobile device cannot be accepted is output and transmitted to the mobile device 71 via the above-mentioned communication path and wireless channel (FIG. 9 (c)).

Therefore, the operator of the mobile device 71 is alerted to the effect that "it is necessary to perform the registration procedure" by such a message, and the registration procedure is prompted (FIG. 9 (d)).

It is to be noted that the above-mentioned unauthorized use mobile unit 2
As for the outgoing calls from the second time onward, the acceptance of the outgoing call is rejected by sending the forced disconnection request, which has the same composition as the location registration request and the same composition as the location registration refusal notification as described above.
