Abstract

PROBLEM TO BE SOLVED: To limit the use of a portable phone within a specific area and to permit the use of the portable phone in an emergency or the like. SOLUTION: The system is provided with a use limit device 105 that covers a use limit area 108 and transmits a control signal similar to that by a base station and a use limit message. The system allows a mobile terminal 101 moving in the use limit area 108 to recognize the use limit device 105 as a base station so as to apply idle hand-off to the mobile terminal 101, allows the mobile terminal 101 to receive the use limit message so as to transmit it to an operation limit mode thereby limiting call transmission of the mobile terminal 101. Since the mobile terminal 101 receives control information from the use limit device by using a long code mask corresponding to the use limit device 105 in this state, the mobile terminal 101 does not receive an incoming message by paging from base stations 102, 103 so as to limit the arrival of incoming calls to the mobile terminal 101.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a CDMA mobile communication system will be described.

FIG. 1 is a diagram showing an example of a system configuration according to the present invention. The mobile terminal 101 has the time t0->t1-> t
Assume that it moves to 2. Base stations 102 and 103
Is connected to the mobile terminal 101 via a wireless line. The exchange 104 is connected to the base stations 102 and 103 and performs circuit switching within the mobile network and with the public network. The terminal use restriction device 105 installed in a movie theater, a concert hall, a hospital, or the like notifies a specific control message and regulates the use of the mobile terminal 101. The base station 102 provides a communication service to mobile terminals existing in the service area 106. Service area 107 is for base station 103. The area 108 is an area in which the terminal use restriction device 105 restricts the use of the mobile terminal.

In the case of this example, the mobile terminal 101 at time t0 is in a state of receiving the control message of the base station 102, and is in a state of being able to communicate with each other via the base station 102 whenever necessary. On the other hand, the mobile terminal 101 at times t1 and t2 is receiving the control message from the terminal use restriction device 105, and communication is restricted by any of the following embodiments.

(Embodiment 1) In this embodiment, use of the mobile terminal 101 is restricted by causing the terminal use restriction device 105 to idle handoff the mobile terminal 101 entering the area 108. More specifically,
The terminal use restriction device 105 broadcasts base station identification information on a pilot channel, and further broadcasts a pseudo control message on a paging channel. Terminal use restriction device 105
Does not receive the access channel control message and ignores it even if there is access from the mobile terminal 101. In this way, the use of the mobile terminal 101 is restricted.

[0011] Here, the pilot channel is a channel that is spread-modulated with a PN offset that differs for each base station. When the mobile terminal is powered on, it first attempts to capture this channel. Also, the mobile terminal measures the reception strength of the pilot channel of the adjacent base station and uses it as a criterion for handoff execution.

The paging channel is a channel for the base station to transmit a message such as system information or a response message of a transmission message to a mobile terminal.

An access channel is a channel used by a mobile terminal to transmit a message to a base station. Outgoing requests and the like are transmitted through this channel.

Transmits outgoing messages, etc.

The base station identification information is used for discriminating a base station or a terminal use restriction device, and is a PN code offset applied when transmitting a pilot channel.
The PN code offset is a time lag from a standard time of the system, and indicates a code start timing. This PN code offset differs for each base station.

FIG. 2 shows a terminal use restriction device 10 according to this embodiment.
5 shows a configuration example. Referring to FIG. 2, terminal use restriction apparatus 105 includes antenna section 201 for transmitting a radio signal, R
F section 202, pilot channel modulation section 203 that modulates a pilot signal into a radio signal and transmits it to RF section 202, paging channel modulation section 204 that modulates a control message transmitted on a paging channel into a radio signal and transmits it to RF section 202, pilot signal And a transmission control unit 205 for controlling transmission of the control message, a message creation unit 206 for creating a control message and instructing the transmission / reception control unit 205 to issue a transmission request, and a control unit (CPU) 207 including the message creation unit 206.

The pilot channel modulation section 203,
The paging channel modulator 204 performs spread modulation using at least one spread code. For example, as the identification code of the terminal use restriction device, the same code as the spread code assigned to the identification of a general wireless base station is assigned. For example, a predetermined PN (pseudo noise) code offset is spread for each channel by a given spreading code. In addition, identification between channels is performed using an orthogonal code or the like. In any case, the spreading code may be appropriately set at the time of manufacture or installation of the terminal use restriction device according to the standard of the mobile communication system to which the present invention is applied.

FIG. 3 is an example of a signal processing sequence in the present embodiment. Hereinafter, an operation example in which the mobile terminal 101 located outside the use restricted area moves into the use restricted area 108 and its use is restricted will be described.

First, when installed in a place where use is to be restricted, the terminal use restriction device 105 sends out a pilot channel with such a strength as to cover an area 108 in which use is to be restricted. The transmission power of the pilot channel transmitted from the terminal use restriction device 105 is determined by autonomously setting the mobile terminal 101 in the area 108 to the terminal use restriction device 105.
It is sufficient if the transmission power is such that the idle handoff is performed. The specific transmission power value may be determined based on a relative relationship with the transmission power values of the base stations around the installation area. Idle handoff is different from base station switching during a call, and refers to switching a base station that waits for an incoming call or the like during a non-call. Further, the pilot channel transmitted by terminal use restriction device 105 can be called a handoff promotion signal because it promotes autonomous handoff to mobile terminal 101.

Since the terminal use restriction device 105 appears to the mobile terminal 101 as a normal base station, the idle handoff operation performed by the mobile terminal 101 is similar to the idle handoff operation from the normal base station to the base station. Operation.

The base station 102 is transmitting a control message on a paging channel (601). At time t0, the mobile terminal 101 receives various control messages from the base station 102 from the paging channel and establishes system synchronization (602). That is, the mobile terminal 101
Is performing idle handoff to the base station 102, and both outgoing and incoming calls are performed via the base station 102.

[0022] The system synchronization is a state in which the mobile terminal has left the out-of-service state and is capable of receiving a message from the base station or the use restriction device.

The terminal use restriction device 105 generates a pilot channel by performing spreading modulation with a spreading code having a PN offset different from that of a neighboring base station in a pilot channel modulation section 203, converts the pilot channel to a radio frequency in an RF section 202, It is transmitted from the unit 201 (604). Also, the pseudo control message created by the message creation unit 206 is spread-modulated by the paging channel modulation unit 204, and
The signal is converted into a radio frequency in 2 and transmitted from the antenna unit 201 (607).

The mobile terminal 101 is a terminal use restriction device 10
Search for pilot channels of neighboring base stations including 5;
The pilot channel strength of each base station is measured.

Thereafter, the mobile terminal 101 moves in the direction of the arrow, and when it reaches the point of time t1 (603), the pilot channel strength from the terminal use restriction device 105 is higher than that of the peripheral base station 102. Is detected (60
5). To the mobile terminal 101, since the terminal use restriction device 105 looks like a base station, idle handoff is performed on the terminal use restriction device 105 upon detection of the strong electric field pilot channel (606). In this state,
The mobile terminal 101 synchronizes the system by receiving the pseudo control message from the terminal use restriction device 105 (608).

Next, when the mobile terminal 101 receives an outgoing call request from the user (609), it transmits an outgoing message via the access channel (610), but the terminal use restriction device 105 ignores the message on the access channel. (611), the mobile terminal 101 cannot receive an acknowledgment for the outgoing message. As a result, the mobile terminal 101 fails to access the base station,
Transmission is restricted (612).

There are several ways to ignore the access channel. For example, the access channel demodulation unit need not be configured in the terminal use restriction device 105. Alternatively, even if an access channel demodulation unit is provided, the demodulation operation is not actually performed, or if the demodulated content is an outgoing message even after demodulation, then return to the normal terminal restriction mode. The terminal use restriction device 105 may be configured in the first place.

The terminal use restriction device 105 also regulates incoming calls from the base station to the mobile terminal 101. The mobile terminal 101
The mobile terminal 101 performs idle handoff to the terminal use restriction device 105.
A spreading code used by the terminal use restricting device 105 is determined from a pilot channel transmitted by the terminal 05, and the spreading code is set in a spreading demodulation unit for a paging channel.

The mobile terminal 101 has a spreading code different from the spreading code of the base station 102, so that the base station 10
2 paging channel cannot be despread demodulated. This is a technical idea of restricting the incoming call by taking advantage of the property that the mobile terminal 101 receives only from the base station during idle handoff. This method has the advantage that no modification of the mobile terminal is required.

(Embodiment 2) FIG. 4 shows another embodiment of the terminal use restriction device 105. The terminal use restriction device 105 has a function of receiving an access channel in addition to broadcasting the pilot channel and the paging channel. In this case, if there is access from the mobile terminal,
Restrict use by replying to a rejection message. Also in this method, the existing mobile terminal can be regulated.

Referring to FIG. 4, the terminal use restriction device 10
Reference numeral 5 denotes an access channel demodulation unit 305 that demodulates a radio signal of an access channel received from the RF unit 202, controls transmission of a pilot signal and a control message on a paging channel, and transmits and receives a control message on an access channel. A control unit 306 and a control unit (CPU) 207 are included. The control unit 207 analyzes the message output from the transmission / reception control unit 306, creates a rejection message when instructed by the message analysis unit 307 to return a rejection message, and sends the rejection message to the transmission / reception control unit 306. A message creation unit 308 for instructing a transmission request is included.

FIG. 5 shows a signal sequence in this embodiment. The description of the same sequence as in FIG. 3 is omitted. First, when there is a call request from the user (60
9), the mobile terminal 101 starts transmitting the outgoing message on the access channel (610). Transmission / reception control unit 306
Causes the access channel demodulation unit 305 to demodulate the access channel transmitted by the mobile terminal 101, extract the outgoing message, and send the extracted message to the message analysis unit 307. When the message analysis unit 307 determines that the message from the mobile terminal 101 is an outgoing message, it instructs the message creation unit 308 to create a rejection message (701). Message analysis unit 3
The message creating unit 308 that created the rejection message based on the instruction from 07 outputs the rejection message to the transmission / reception control unit 306. The transmission / reception control unit 306 spreads and modulates the rejection message in the paging channel modulation unit 204 to create a paging channel, frequency-converts this in the RF unit 202, and transmits it to the mobile terminal 101 from the antenna unit 201 (702). This limits the use of mobile terminals.

The mobile terminal 101 uses the spreading code of the terminal use restriction device 105 to
, A paging message from the base station cannot be received, and the incoming call is also restricted. Also in this method, there is no particular need to modify the mobile terminal.

(Embodiment 3) FIG.
14 shows a configuration example of a terminal use restriction device of still another embodiment. The terminal use restriction device 105 includes a non-restricted number storage unit 409 (409 may be stored in the mobile terminal) for storing a list of numbers of emergency calls and the like, and the handoff instruction unit 4.
10 includes a neighboring base station Pilot PN storage unit 412 which is referred to to determine a base station to be handed off. The control unit 207 receives the reception indication from the transmission / reception control unit 306 and analyzes the message.
7. If the received message is an outgoing message, whether the outgoing message has an emergency call indicator set, or whether the called party number in the received outgoing message is listed in the unrestricted number storage unit An emergency call determination unit 408 for determining whether or not the call is an emergency call, a handoff instruction unit 410 for instructing a legitimate base station to handoff the mobile terminal when the emergency call determination unit determines that the call is an emergency call, a message And a message creation unit 411 that instructs the transmission / reception control unit 306 to issue a transmission request.

The emergency call indicator is information indicating whether or not the call is an emergency call, stored in the emergency call indicator field in the outgoing message. For example, 0 may be stored in this field for a normal call, and 1 may be stored for an emergency call.

FIG. 7 shows a mobile terminal 101 according to this embodiment.
An example of the configuration will be described. The mobile terminal 101 includes an antenna unit 501 for transmitting and receiving a radio signal, and an RF unit 50 for performing frequency conversion.
2. A pilot channel demodulation unit 503 for demodulating a pilot channel signal, a paging channel demodulation unit 504 for demodulating a paging channel radio signal received from the RF unit 502, and modulating a control message transmitted on an access channel into a radio signal to RF Access channel modulation section 505 for transmitting to section 502, pilot strength measurement section 50 for measuring pilot strength from received pilot signal
6. Transmission / reception control unit 50 for controlling transmission / reception of messages
7. It includes a non-restricted number storage unit 513 and a control unit 514 for storing numbers for which use restrictions such as emergency calls should be avoided.

The control section 514 includes a pilot strength measurement section 5
Handoff determination unit 50 that determines whether to perform idle handoff based on the pilot strength measured at 06.
8. A message analysis unit 509 for analyzing a message received from the transmission / reception control unit 507, a transmitter stop instruction for instructing the transmission / reception control unit to stop the transmitter when the message analyzed by the message analysis unit is a use restriction message Unit 510, a message creating unit 511 for creating a message such as an outgoing message, and referring to the unrestricted number storage unit 513 to determine whether or not the dialed number is an unrestricted number such as an emergency call. It includes an emergency call determination unit 512 that instructs a message creation unit to create an outgoing message with an emergency call indicator set. Note that 512 and 513 may be included in the terminal use restriction device, and in that case, they are not included in the mobile terminal. The transmitter is
It refers to a part related to transmission from the RF unit to the transmission / reception control unit in the figure. On the other hand, the receiver refers to a part related to reception from the RF unit to the transmission / reception control unit in the figure.

FIG. 8 is a sequence diagram showing signals and operations transmitted and received among the base station, the mobile terminal, and the terminal use restriction device in the present embodiment.

The base station 102 is transmitting a control message on a paging channel (801).

The mobile terminal 101 searches for a pilot channel from a neighboring base station at an appropriate period, and the pilot strength measuring unit 506 measures the pilot strength. At time t0, mobile terminal 101 receives the paging channel of base station 102 by antenna section 501, and
The paging channel demodulation unit 504 performs despread demodulation and receives various control messages of the base station 102 (802). The mobile terminal 101 synchronizes the system with the base station 102 by the control message, and is in a state where a call through the base station 102 can be freely received.

On the other hand, terminal usage limiting apparatus 105 transmits a pilot channel spread with a pilot offset different from the pilot offset of the pilot channel transmitted by the neighboring base station (804).

When the mobile terminal 101 moves in the direction of the arrow and reaches the point of time t1 (803), the pilot strength measuring unit 506 detects that the pilot strength from the terminal use restriction device 105 is sufficiently high (803). 805). When the strong electric field pilot channel is detected by pilot strength measuring section 506, handoff determining section 508 determines idle handoff to terminal use restriction apparatus 105 (8).
06).

The message creation unit 411 sends the message to the mobile terminal 10
A use restriction message for restricting the use of No. 1 is created. The use restriction message is a so-called command signal for commanding the mobile terminal to stop the transmission operation. Note that a command signal for commanding the intermittent operation of the receiver of the mobile terminal to perform the intermittent operation at a longer interval than usual may be added to the usage restriction message. This is because power consumption is reduced by reducing useless operation of the receiver of the mobile terminal until the incoming call restriction is released.

The transmission / reception control section 306 outputs the use restriction message to the paging channel modulation section 204, and the paging channel modulation section 204 spread modulates the use restriction message to create a paging channel. The created paging channel is transmitted via the RF unit 202 and the antenna unit 201 (807).

The transmission / reception control unit 507 of the mobile terminal 101
When the usage restriction message is received from the terminal usage restriction device 105, it is sent to the message analysis unit 509. When determining that the message is a transmission operation stop command, the message analysis unit 509 instructs the transmitter stop instruction unit 510 to stop the transmitter. The transmitter here mainly refers to a channel modulator. Transmitter stop instruction section 510 instructs transmission / reception control section 507 to stop transmission. Thus, the transmission / reception control unit 507 shifts to the transmission operation restriction mode (808). The mobile terminal 101 displays on the display unit that the current location is within the restricted use area (809).

When the message analysis unit 509 determines that the message is an intermittent operation command of the receiver, it instructs the transmission / reception control unit 507 to operate the receiver to wait for an incoming call at a longer interval than usual. . The receiver here mainly refers to a channel demodulation unit.

FIG. 9 is a diagram showing a display example of the display when the mobile terminal is in the use restricted area. When the mobile terminal 901 moves into the use-restricted area and receives a use-restriction message from the terminal use-restriction device, the mobile terminal 901 displays "currently in the mobile-phone use-restricted area" on the display unit, and informs the user of the use restriction area Is explicitly shown.

Instead of displaying the information, a small sound may be output from the speaker. When a vibration receiving unit is provided, the vibration may be vibrated in a predetermined vibration format. In this case, if the user vibrates in a manner different from the vibration at the time of the normal incoming call, the user will be able to recognize that the incoming call is not the incoming call and the user has entered the restricted use area.

Paging channel modulation section 204 of terminal use restriction apparatus 105 spread modulates the pseudo control message created by message creation section 411. The paging channel is transmitted from the antenna unit 201 (810).

Note that the mobile terminal 101 operating in the operation restriction mode does not transmit an outgoing message even when a call request is made by the user because the transmitter is in a stopped state (however, a description will be given next). Except for the case of sending an emergency call.) Note that, even in this state, the receiver continues to operate, and continues to receive the pseudo control message from the terminal use restriction device. As a result, system synchronization is maintained, and an emergency call can be immediately transmitted as described below.

In this state, the terminal use restriction device 10
5 has received the control message from base station 1,
No incoming message is received by paging from 02, and incoming calls can be restricted. When the mobile terminal 301 leaves the restricted area 307, handoff is performed to a regular base station, and the mobile station 301 returns to the normal operation mode. This method requires modification of the mobile terminal, but has the effect of eliminating any transmission of radio waves from the mobile terminal.

(Embodiment 4) In the present embodiment, even if the mobile terminal is in the restricted area, it is possible to make a specific call possible. This is because emergency calls and the like should be prioritized even during use restrictions.

FIG. 10 is a diagram showing an example of an unrestricted number list 1001 stored in a mobile terminal or a terminal use restriction device in order to avoid restrictions on use of a mobile phone in an emergency or the like. This is to make it possible to perform a calling process when the number dialed by the user is included in the unrestricted number list even when the mobile terminal is in the restricted area. The non-restricted number list 1001 only needs to store a telephone number such as an emergency call. Accordingly, the names of the police, fire department, etc., which are the main telephone numbers, may be provided as needed.

FIG. 11 is a sequence diagram in the case where the unrestricted number list 1001 is included in the mobile terminal 101 and a call is made using the unrestricted number. The mobile terminal 101 is in the operation restriction mode, and cannot perform normal call processing. The terminal use restriction device 105 periodically broadcasts the pseudo control message (1101). The mobile terminal 101
By receiving the pseudo control message, system synchronization is maintained (1102).

First, when a user dials an emergency call number (1103), the emergency call determination unit 512 analyzes the dial number and stores the unrestricted number list 1001 in the unrestricted number storage unit 513 and the dial number. Compare (110
4). In this example, since the dialed number is included in the unrestricted number list 1001 of the unrestricted number storage unit 513,
The emergency call determination unit 512 recognizes that the call is an emergency call, and instructs the message creation unit 511 to create an outgoing message in which an emergency call index is set (1105).

Message creation section 511 creates an outgoing message in which an emergency call index is set, makes a transmission request to transmission / reception control section 507, and transmission / reception control section 507 activates the transmitter, and transmits the message via access channel modulation section 505. A message is transmitted to the terminal use restriction device 105 (11
06).

Terminal use restriction device 105 detects an emergency call index from the outgoing message received by message analysis unit 407 via access channel demodulation unit 405, and accepts the emergency call (1107). The handoff instructing unit 410 stores the neighboring base station information in the neighboring base station Pilot PN storage unit 4
12, the base station 102 instructing the handoff is selected (1108). Usually, the one having the strongest pilot channel strength is selected.

The message creating section 411 creates an emergency call handoff message instructing an emergency call handoff. This message includes the pilot PN sequence offset of the handoff destination base station. The emergency handoff message is sent to the paging channel modulator 2
The signal is spread-modulated at 04 and transmitted to the mobile terminal 101 via the antenna unit 201 (1109).

Through paging channel demodulation section 504,
The mobile terminal 101 that has received the emergency call handoff message in the message analysis unit 509 performs a handoff to the base station having the pilot PN sequence offset specified in the message (1110). Specifically, the pilot PN sequence offset specified in the message is set in pilot channel demodulation section 503 as a spread code for spread demodulation.

After the handoff is performed, when the control message transmitted by the base station 102 is received and the updating of the control message of the mobile terminal 101 is completed, the mobile terminal 101 shifts to a state where transmission and reception with the base station 102 are possible (1111, 111).
2).

Next, the message creating section 511 creates an outgoing message including the previous dial number in order to recall the emergency call (1113). Access channel modulator 505 spread modulates the outgoing message. RF unit 50
2 performs necessary frequency conversion and transmits (1114).
Thereafter, the procedure for call setting is performed as usual.

FIG. 12 shows a sequence in the case where the unrestricted number list is included in the terminal use restriction device 105 and a call is made using the unrestricted number.

The terminal use restriction device 105 periodically broadcasts a pseudo control message (1201). Mobile terminal 1
01 is in a state of maintaining system synchronization by receiving the pseudo control message (1202). The user dials the emergency call number (1203). Mobile terminal 10
The first message creation unit 511 creates an outgoing message and instructs the transmission / reception control unit 507 to transmit. The transmission / reception control unit 507 transmits the outgoing message to the terminal use restriction device 105 via the access channel modulation unit 505 (12
04). On the other hand, via the access channel demodulation unit 405,
The message analysis unit 407 of the terminal use restriction device 105 that has received the outgoing message passes the dial number included in the outgoing message to the emergency call determination unit 408, and the emergency call determination unit 408 analyzes the dial number (1205), and unrestricts. The unrestricted number list 1001 in the number storage unit 409 is compared with the dialed number (1206). In this example, since the dialed number is included in the unrestricted number list 1001 of the unrestricted number storage unit 409, the emergency call determination unit 408 recognizes that the call is an emergency call and the handoff instruction unit 410
Notify. The handoff instructing unit 410 determines a base station to instruct a handoff from the neighboring base station Pilot PN storage unit 412 holding the neighboring base station information (120).
7). The message creation unit 411 creates an emergency call handoff message indicating the base station's pilot PN sequence offset, which instructs handoff for an emergency call, and instructs the transmission / reception control unit 406 to request transmission. The transmission / reception control unit 406 transmits an emergency call handoff message to the mobile terminal 101 via the paging channel modulation unit 404 (1208). On the other hand, the mobile terminal 101 that has received the emergency call handoff message at the message analysis unit 509 via the paging channel demodulation unit 504 of the mobile terminal 301 performs handoff to the base station having the specified pilot PN sequence offset ( 12
09). After the handoff, a control message is received from the base station 102 (1210, 1211). After updating all the control messages, the message creating unit 511 creates an outgoing message including the previous dial number (1).
212). The RF unit performs necessary frequency conversion and transmits the result to the base station 102 (1213). Thereafter, the procedure for call setting is performed as usual.

Next, the operation of the terminal use restriction device 105 according to the present invention will be described with reference to FIG. The terminal use restriction device 105 is installed in the use restriction area 108. Here, the mobile terminal 101 must be able to handoff to the terminal use restriction device 105 as in the case of a normal base station. Therefore, terminal use restriction apparatus 105 sets a pilot PN offset different from that of the neighboring base station as a code for distinguishing pilot signals (130).
1). This setting may be set at the time of manufacture or installation, or may be set independently by the terminal restriction device 105 in consideration of the situation of the surrounding base station.

Next, the terminal use restricting device 105 stores the system parameters for transmitting the control message and accepting the emergency call and the configuration of the neighboring base station (such as the pilot PN offset of the neighboring base station) in the storage device. 13
02). The terminal use restriction device 105 transmits a pilot signal with the set pilot PN offset (130).
3). Further, the control message and the use restriction message are periodically transmitted to the broadcast address on the paging channel (1304). When the receiving system receives the message (1305), it determines whether the message is an outgoing message (1306). If the message is not an outgoing message, a use restriction message or a rejection message is transmitted to the target mobile station (1307). If the message is an outgoing message, the dial number is analyzed (1308). This processing corresponds to the analysis of the emergency call index when the unrestricted number list is held in the mobile terminal. The number obtained by the number analysis is compared with the unrestricted number list (130).

On the other hand, in the case of an emergency call, the terminal use restriction device determines the handoff destination base station from the neighboring base station information (1311). Next, the terminal use restriction device transmits an emergency call handoff message to the target mobile station (13).

It is included.

The emergency call determination unit 1614 and the unrestricted number storage unit 1615 may be included in the terminal use restriction device. In this case, the mobile terminal 101 transmits an outgoing message, and determines an emergency call in the terminal use restriction device 105.

Next, an operation example in the case where the mobile terminal 101 moves from the normal service area 106 to the use restricted area 108 (on a train or a bus) covered by the terminal use restriction device 105 will be described with reference to FIGS. It is shown using.

The terminal use restriction device 105 is installed in a train or a bus, and transmits a pilot channel with such a strength as to cover the inside of a vehicle. This pilot channel is generated by performing spread modulation by pilot channel modulator 1505 with a PN offset different from that of the adjacent base station. The pilot channel is transmitted from the RF unit 1502 and the antenna unit 1501 (804). The mobile terminal may be handed off to the terminal use restriction device by making this pilot channel a special signal that can be distinguished from the base station.

Terminal use limiting apparatus 105 spreads and modulates the pseudo control message created by message creating section 1514 with paging channel modulator 1506 in order to make mobile terminal 101 look like terminal use limiting apparatus itself. A paging channel is generated and transmitted (810).

Terminal use restricting apparatus 105 prepares a use restriction message for restricting the use of the mobile terminal by message preparation section 1514, and sets paging channel modulation section 1
A paging channel is generated and transmitted by performing spread modulation in 506 (807).

On the other hand, the base station 102 is transmitting a control message on a paging channel (801).

At time t0, mobile terminal 101 receives various control messages from base station 102 on the paging channel via paging channel demodulation section 1604 (802), and is in a state of system synchronization. In this state, the mobile terminal 101 can freely perform both outgoing and incoming calls via the base station 102.

Thereafter, when mobile terminal 101 moves in the direction of the arrow and reaches the point of time t1, pilot strength measuring section 1608 detects the pilot channel of terminal use restriction device 105 as a strong electric field pilot (805). The fact of this detection is notified to the handoff determination unit 1610.

The handoff determination unit 1610 notified of the detection of the strong electric field pilot determines an idle handoff to the terminal use restriction device 105 (806). After performing the idle handoff, the mobile terminal 101 receives the paging channel of the terminal use restriction device 105, performs despread demodulation by the paging channel demodulation unit 1604, and sends the demodulated use restriction message to the message analysis unit 1611 (80).
7).

The message analysis unit 1611 analyzes the message, and if it determines that the message implies a use restriction, instructs the transmitter stop instruction unit 1612 to stop the transmitter. The transmitter stop instructing unit 1612
9, the transmission / reception control unit 160 is instructed to stop the transmitter.
9 shifts to the operation restriction mode (808).

The mobile terminal operating in the operation restriction mode does not transmit an outgoing message even if there is a call request from the user since the transmitter is in a stopped state. However, this is not always the case when an emergency call is issued (the calling process using the emergency call number will be described later).

The mobile terminal 101 displays to the user that the current area is the restricted area and that the mobile terminal 101 is operating in the restricted operation mode through its own display (809). A display example is as shown in FIG.

The mobile terminal 101 receives a signal from the terminal use restriction device 105 using the long code mask corresponding to the terminal use restriction device 105, and receives signals from the base stations 102 and 103 having different long code masks. Because no incoming message is received by paging, the incoming call is also restricted.

Note that, even in the mobile terminal 101, the receiver continues to operate normally even in the operation restriction mode, and the pseudo control message from the terminal use restriction device 105 is transmitted to the message analysis unit 161 via the paging channel demodulation unit 1604.
1 (811), and system synchronization is maintained.

Thus, for an emergency call, a calling process can be immediately performed as described later. When the mobile terminal 101 leaves the restricted area 108, the base station performs idle handoff as before, and the message analyzing unit 1611 does not receive the restricted message for a certain period of time, thereby returning to the normal operation mode. .

(Embodiment 6) The purpose of this embodiment is to restrict the use of mobile terminals in a moving body such as a train, a car, and an airplane. In this case, not only the mobile terminal but also the terminal use restriction device will move with the movement of the vehicle, but the movement of the terminal use restriction device should not affect the destination base station as much as possible. It is desired to do.

FIG. 17 shows a state where mobile terminal 101 is present in a vehicle provided with terminal use restriction device 105 and is handing off to terminal use restriction device 105.
In this state, the mobile terminal 101 and the terminal use restriction device 105
Will be described with reference to FIG. 17 and FIG. 18 when the vehicle moves from the base station 102 to the base station 103 together with the movement of the vehicle.

It is important to make the terminal use restriction device portable so that the PN
Setting the offset. To this end, the terminal use restriction device 105 must be able to grasp the use state of the PN offset in the peripheral base station and to set its own PN offset independently. If this can be realized, the effect that the setting to be performed by the user at the time of installation is reduced can be obtained.

In FIG. 17, base station 102 transmits pilot channel 1803 and control message 1805. Base station 103 transmits pilot channel 1804
Is transmitted, the control message 1809 is transmitted. The terminal use restriction device 105 transmits the pilot channel 1812 and the pseudo control messages 1802 and 1815.

FIG. 18 shows a message sequence of the terminal use restricting device, the base station and the mobile terminal, and an operation outline of the mobile terminal and the terminal use restricting device.

First, at time t0, the mobile terminal 101
Is operating in the use limitation mode (1801), and the pseudo control message constantly transmitted by the terminal use limitation device 105 is received by the message analysis unit 1611 via the paging channel demodulation unit 1604 (transmitter Is stopped) (1802).

Terminal use restricting apparatus 105 constantly transmits pilot channel signals from neighboring base stations such as base station 102 and base station 103 to pilot channel demodulating section 15.
03 (1803 and 1804), the strength is measured by the pilot strength measuring unit 1508, and the measurement result (pilot strength) is set in the neighboring base station information storage unit 1517. Also, a control message from the base station 102 is received by the message analysis unit 1511 via the paging channel demodulation unit 1504 (1805), and neighboring base station information (Pilot PN information of the neighboring base station) is received from the received message. This is set in the station information storage unit 1517.
FIG. 19 shows an example of the adjacent base station information table 1901 held in the adjacent base station information storage unit 1517.

[0094] The terminal use restriction device is used together with the mobile terminal in FIG.
7 (1806), the pilot strength measuring section 1508 of the terminal use restriction device 105 detects the pilot channel signal from the base station 103 as a strong electric field pilot (1807), and determines the pilot strength to the adjacent base station. Adjacent base station information table 1 of station information storage section 1517
901 is set. Idle handoff determination unit 1510
Refers to the adjacent base station information table 1901 of the adjacent base station information storage unit 1517, and as a result, determines to perform idle handoff to the base station 103, and switches to a long code mask corresponding to the base station 103 to perform idle handoff. (1808). The terminal usage restriction device 105 receives the control message from the base station 103 via the paging channel demodulation unit 1504 by the message analysis unit 1511 (1809), updates the adjacent base station information (1810), and stores the adjacent base station information storage unit. 1517 in the adjacent base station information table 801.

Next, the own station Pilot PN determining unit 1515
With reference to the adjacent base station information table 1901 of the adjacent base station information storage unit 1517, a Pilot PN sequence offset that does not overlap with the Pilot PN sequence offset of the adjacent base station is selected. For example, in the example of the adjacent base station information table 1901, AAA or the like not used by the adjacent base station is selected as the Pilot PN sequence offset.
The own-station Pilot PN determination unit 1515 determines whether the terminal use restriction device 10
The Pilot PN sequence offset of 5 to the selected Pilot
It instructs the message creation unit 1511 and the transmission / reception control unit 1509 to switch to the PN sequence offset (1811).

[0096] Transmission / reception control section 1509 instructs pilot channel modulation section 1505 to generate a pilot channel with the newly determined Pilot PN sequence offset. The pilot channel generated by pilot channel modulation section 1505 is transmitted through RF section 1502 and antenna section 1501 (181).
2).

[0097] Pilot strength measuring section 1 of mobile terminal 101
608 is a new Pilot from the terminal use restriction device 105.
A pilot channel having a PN sequence offset is detected as a strong electric field pilot channel (181).
3). Based on this detection, the handoff determination unit 1610 determines that idle handoff should be performed at the new Pilot PN sequence offset of the terminal use restriction device 105, and instructs the transmission control unit 1609 to perform idle handoff at the new Pilot PN sequence offset. Transmission control unit 1
609 instructs the modulation / demodulation units 1603 to 1607 of each channel to perform modulation / demodulation with the new Pilot PN sequence offset (1814). In this process, Pilot
Although the PN is switched, the handoff to the terminal use restriction device 105 is still performed.

In this state as well, mobile terminal 101 transmits a pseudo control message including a use restriction message from terminal use restriction device 105 to paging channel demodulation section 160.
4 and received by the message analyzer 1611, and the operation in the use restriction mode is continued.

(Embodiment 7) Next, an operation example when an emergency call is issued when a mobile terminal is present in a restricted use area such as a train or a bus and the use thereof is restricted. This will be described with reference to FIG. Here, the time of FIG.
When the user makes an emergency call at t2,
An operation example when the emergency call number list shown in FIG. 10 is stored in the non-restricted number storage unit 1516 in the terminal use restriction device will be described.

First, referring to FIG. 10, reference numeral 1001 denotes an unrestricted number list stored in the mobile terminal and the terminal use restriction device in the present invention in order to avoid use restriction of the mobile terminal in an emergency or the like. It is a figure showing an example. This is to make it possible to perform a calling process when the number dialed by the user is included in the unrestricted number list even when the mobile terminal is in the restricted area.

The unrestricted number list 1001 is desirably held in the unrestricted number storage unit 1516 in the terminal use restriction device in order to minimize the modification of the mobile terminal. Therefore, this example shows an example in which the unrestricted number list 1001 is included in the unrestricted number storage unit of the terminal use restriction device. If it is included in the unrestricted number storage unit 1615 in the mobile terminal, the operation is performed to analyze the dialed number in the mobile terminal and determine whether or not to send a call message.

At time t2, the mobile terminal 101 is in the operation restriction mode, and is in a state where normal call processing cannot be performed (2001). The terminal use restriction device 105 creates a pseudo control message in the message creation unit 1514, and constantly transmits the pseudo control message via the paging channel modulation unit 1506 (2002). As a result, the mobile terminal 101 is in a state of maintaining system synchronization by receiving the pseudo control message via the paging channel demodulation unit 1604 by the message analysis unit 1611.

Terminal use limiting apparatus 105 always receives a pilot channel signal from a neighboring base station via pilot channel demodulation section 1503 (2003/2004), measures its pilot strength by pilot strength measurement section 1508, and obtains the measurement result ( Pilot strength) is set in the adjacent base station information storage unit 1517 (2006).

At time t2, terminal use restriction device 10
Reference numeral 5 indicates that the control message from the base station 103 is constantly received by the message analyzer 1511 via the paging channel demodulator 1504, and the received neighboring base station information (Pilot PN information of the neighboring base station) is transmitted to the neighboring base station information. Storage unit 15
17 (2006).

The user dials the emergency number "119" (2007). The mobile terminal 101 creates an outgoing message in the message creating unit 1613, and
609, the access channel modulator 1
The data is transmitted to the terminal use restriction device 105 via 605 (2008).

The terminal use restriction device 105 receives the outgoing message via the access channel demodulation unit 1507 by the message analysis unit 1511. The dial number of the received outgoing message is analyzed by the emergency call determination unit 1512 and compared with the unrestricted number list 1001 in the unrestricted number storage unit 1516.

Since the dial number “119” is included in the unrestricted number list 1001, the emergency call determination unit 1512 determines that the call is an emergency call (2010), and the handoff instruction unit 1513.
Notify. In the handoff instructing unit 1513, the adjacent base station information table 190 of the adjacent base station information storage unit 1517 is used.
1, the base station 103 having the highest pilot strength is selected (2011), and the message creation unit 1514 is instructed to create a handoff instruction message designating the base station 103.

[0108] The message creation unit 1514 checks the base station 1
A handoff instruction message designating the Pilot PN sequence offset value of 03 is created, and the transmission / reception control unit 1509 is created.
To the transmission request, and paging channel modulator 150
6, a handoff instruction message is sent to the mobile terminal 101.
(2012).

Mobile terminal 101 that has received the handoff instruction message modulates using access channel modulating section 1605 using a long code mask including the designated Pilot PN sequence offset, and retransmits the outgoing message (2013). In this case, the outgoing message is the base station 1
03, and the subsequent processing is performed by the mobile terminal 10.
1 and the base station 103 can be performed in the same manner as a normal calling process.

Next, an operation flow of the terminal use restriction device according to the present invention will be described with reference to FIG. First,
The terminal use restriction device constantly transmits a pilot signal having a Pilot PN sequence offset different from that of the neighboring base station (2101). Also, the terminal use restriction device constantly transmits a pseudo control message and a use restriction message on the paging channel (2102). Further, a pilot signal from a neighboring base station is constantly received (210).
3) The pilot strength is measured and stored. Further, it receives a control message from a currently active (handoffed) base station on a paging channel and stores information on neighboring base stations.

Next, based on the pilot strength of the adjacent base station, the necessity of idle handoff to another base station that is not currently active (handoff is being performed) is always determined (2105). When it is determined that idle handoff is necessary, the long code mask of the paging channel receiving system is switched to the long code mask of the base station of the idle handoff destination (2106), idle handoff is performed, and the paging channel from the new base station is transmitted. The reception is continued (2104).

Next, the terminal use restriction device transmits the Pilot of its own station.
The necessity of switching the PN sequence offset is always determined (2107). If there is a base station using the same Pilot PN sequence offset as the terminal use restriction device in the neighboring base station, the switching of the Pilot PN sequence offset of the own station is determined (2108). After the switching, a pilot signal having a new Pilot PN sequence offset is constantly transmitted (2101). The terminal use restriction device always performs the processing up to this point.

On the other hand, the terminal use restriction device waits for reception of an outgoing message from the mobile terminal on the access channel (2109). When the outgoing message is received, the dial number included in the outgoing message is analyzed (2110). If the result of the number analysis indicates that the call is not an emergency call, a rejection message is transmitted to the mobile terminal (2112), and the call is not permitted. If the result of the number analysis indicates an emergency call,
The base station having the highest pilot strength is determined as the base station of the handoff destination (2113), and a handoff instruction message is transmitted to the mobile terminal so as to perform handoff to the base station determined in 2113 and retransmit the outgoing message (2113). 2114). The terminal use restriction device waits for the next outgoing message.

[0114]

According to the present invention, it is possible to regulate the transmission or reception of mobile terminals such as mobile phones in static areas such as movie theaters and dynamic areas such as trains.

[0115] Further, even if the outgoing or incoming call is being restricted, a specific outgoing call can be communicated.
