The pattern terminal information update request and the pattern schedule information update request made in
In addition, the pattern candidate information and the pattern schedule information stored in the communication setting pattern recording memory 173 are updated according to the request content in response to the request given via the bus 19.

Next, the operation of the communication control device 1 configured as described above will be described. In addition, here, as shown in FIG. 3, the inside of the facility of the leisure facility 21 is set as a service area,
It is assumed that a mobile communication system is constructed by arranging nine radio base stations 3 (3-1 to 3-9) here. Then, the communication area of each wireless base station 3 is set to each wireless zone. The identification name (radio zone name) of each radio zone is Z-1, Z-2, ..., Z-9 in order from the one corresponding to the communication area of the radio base station 3-1.

The purpose of use of each wireless zone is determined as shown in FIG. That is, the wireless zones Z-1 to Z-4, Z-6 are play facilities, and the wireless zones Z-5,
Z-8 and Z-9 are equivalent to the entrance and exit, and Z-7 is equivalent to the multipurpose hall.

Further, the schedule for holding an event in the multipurpose hall is as shown in FIG. 5, and it is assumed that telephone calls need to be restricted during the lecture.

Under the above conditions, the call may be permitted all day in the wireless zones other than the wireless zone Z-7 corresponding to the multipurpose hall, but whether or not the wireless zone Z-7 is giving a lecture. It is necessary to switch the permission / prohibition of the call according to. That is, there are two possible states, a first state in which calls are permitted in all wireless zones and a second state in which calls are prohibited only in the wireless zone Z-7. Therefore, for example, as shown in FIG. 6, for example, the administrator of the system assigns a pattern number “1” to the communication setting pattern indicating the first state and the communication setting pattern indicating the second state. Pattern candidate information with the pattern number “2” is created in advance and registered in the communication setting pattern recording memory 173. Further, for example, as shown in FIG. 7, for example, the administrator of the system shows the pattern number “2” in association with the start time of the lecture and the pattern number “1” in association with the end time of the lecture. The pattern schedule information is created in advance and registered in the communication setting pattern recording memory 173.

When the set time indicated in the pattern schedule information arrives in the state where the above settings are made, the communication setting setting unit 156 in the CPU 15
The communication setting pattern change setting process shown in FIG. 8 is started.
In this communication setting pattern change setting process, the communication setting setting unit 156 reads the pattern number corresponding to the time from the pattern schedule information, and determines this pattern number as the pattern number of the communication setting pattern to be set (step ST1). ). And communication setting setting section 1
The 56 reads the communication setting pattern with the determined pattern number from the pattern candidate information and stores it in the communication setting memory 172 (step ST2). Specifically, for example, when it is 10:00, the pattern number associated with that time is “2”, so the communication setting pattern with this pattern number “2” is stored in the communication setting memory 172. Let As a result, the contents of the communication setting memory 172 become those shown in FIG.

It should be noted that the communication setting setting unit 156 is the maintenance terminal 6
When a request is made to update the communication setting pattern stored in the communication setting memory 172, and the call control unit 153 notifies that, the communication setting pattern stored in the communication setting memory 172 is updated according to the instruction. You can also do

Next, the operation when the call setting request signal is transmitted from the wireless terminal 5 existing in the service area of the communication control device 1 to request the transmission will be described.

When the call setting request signal is transmitted from the wireless terminal 5 as described above, the call setting request signal is received by the wireless base station 3 that can communicate with the wireless terminal 5. This call setup request signal is sent from the wireless base station 3 to the CPU via the communication line 4, the base station interface circuit 13 and the bus 19.
Given to 15. Then, in the CPU 15, the call control unit 153 executes a call setting request time process as shown in FIG. 10 in response to the call setting request signal being given.

That is, the call control unit 153 first causes the terminal position searching unit 154 to search the position of the wireless terminal 5 (hereinafter, referred to as a calling terminal) that has transmitted the call setting request signal (step ST11). In response to this, the terminal position search unit 1
Reference numeral 54 designates the location registration information of the originating terminal in the location registration memory 17
When the corresponding location registration information is found, the location registration information is given to the call control unit 153.

The call control unit 153 has a terminal position searching unit 154.
Based on the response from, it is determined whether or not the location of the calling terminal has been registered (step ST12). Here, when the location registration information of the calling terminal is not given from the terminal location searching unit 154, the call control unit 153 determines that the location of the calling terminal is not registered. At this time, the call control unit 1
53 sends a disconnection instruction signal to the calling terminal (step ST13), and ends the call setup request process. On the other hand, when the location registration information of the calling terminal is given from the terminal location searching unit 154, the call control unit 153 determines that the calling terminal is registered in location. Then, at this time, the call control unit 153 causes the communication setting searching unit 155 to search for the communication setting relating to the wireless zone in which the calling terminal exists (step ST14). In response to this, the communication setting search unit 155 uses the identification number of the wireless zone indicated in the position registration information of the calling terminal as a key to set the communication setting memory 172.
And the communication setting obtained by this is searched for by the call control unit 15

The call control unit 153 has a communication setting search unit 155.
Based on the notification from, it is determined whether or not the call in the wireless zone where the calling terminal is present is prohibited (step ST15). Here, if the call in the wireless zone in which the calling terminal exists is allowed, the call control unit 153 performs the calling process as usual (step ST16). Note that the calling process is a process such as dial analysis, capturing an outgoing line, sending a call setting request to the station (when calling through the station), or generating an incoming call request signal to itself (when calling to the wireless terminal 5). is there. On the other hand, when the call in the wireless zone in which the calling terminal exists is prohibited, the call control unit 153 does not perform the calling process in step ST16. And the call control unit 153
Performs a voice message transmission process (step ST1)
7). This voice message sending process is a process in which the voice announcement device 14 is connected to the calling terminal, and then a voice message such as “I cannot make a call from this wireless zone right now” is sent from the voice announcement device 14.

When the processing of step ST16 or step ST17 is completed, the call control section 153 terminates the call setup request processing.

Next, the operation will be described when the incoming call request signal sent from the station arrives, and when the incoming call request signal is generated in the outgoing call process of step ST16 in the call setting request time process described above.

When the incoming call request signal thus sent from the station arrives via the station line 2, the incoming call request signal is sent to the CP via the station line interface circuit 12 and the bus 19.
Given to U15. Then, in the CPU 15, the call control unit 153 executes the incoming call request time process as shown in FIG. 11 in response to the incoming call request signal being given.

That is, the call control unit 153 first searches for the position of the wireless terminal 5 (hereinafter referred to as the called terminal) designated as the destination by the incoming call request signal.
(Step ST21). In response to this, the terminal location search unit 154 retrieves the location registration information of the called terminal from the location registration memory 171, and if there is the corresponding location registration information, gives the location registration information to the call control unit 153.

The call control unit 153 has a terminal position searching unit 154.
Based on the response from, it is determined whether or not the location of the called terminal has been registered (step ST22). Here, if the location registration information of the called terminal is not given from the terminal location searching unit 154, the call control unit 153 determines that the location of the called terminal is not registered, and terminates the call setup request process. On the other hand, when the location registration information of the called terminal is provided from the terminal location search unit 154, the call control unit 15
3 determines that the location of the called terminal is registered. Then, at this time, the call control unit 153 searches the communication setting relating to the wireless zone in which the receiving terminal exists in the communication setting searching unit 1
55 (step ST23). In response to this, the communication setting search unit 155 searches the communication setting memory 172 using the identification number of the wireless zone indicated in the location registration information of the called terminal as a key, and the call control unit 153 stores the communication setting obtained thereby. Notice.

The call control unit 153 has a communication setting search unit 155.
Based on the notification from, it is determined whether or not the call is prohibited in the wireless zone where the receiving terminal exists (step ST24). Here, if the call in the wireless zone in which the called terminal exists is allowed, the call control unit 153 performs the calling process of the called terminal as usual (step ST25). On the other hand, if the call in the wireless zone in which the called terminal exists is prohibited, the call control unit 153 determines in step ST2.
The call processing of 5 is not performed. Then, the call control unit 153 performs a voice message sending process (step ST26). This voice message sending process is a process in which the voice announcement device 14 is connected to the caller and then a voice message "The number you dialed cannot be connected right now" is sent from the voice announcement device 14. .

When the processing of step ST25 or step ST26 is completed, the call control section 153 terminates the incoming call request processing.

Next, when the communication setting pattern is changed while a call is being made by the wireless terminal 5 accommodated in the communication control device 1, or the wireless terminal 5 accommodated in the communication control device 1 is changed. The operation when the handover process is performed will be described.

When the set time indicated in the pattern schedule information arrives, the communication setting setting unit 156 changes the communication setting pattern as described above. When the change of the communication setting pattern is completed, the communication setting setting unit A pattern change completion signal is supplied from 156 to call control unit 153. In addition, when the call control unit 153 completes the handover process for the wireless terminal 5, the call control unit 153 internally generates a handover completion signal. When the call control unit 153 receives the pattern change completion signal or the handover completion signal, the call control unit 153 executes a call interruption process as shown in FIG.

That is, the call control unit 153 first causes the terminal position searching unit 154 to search for the position of the wireless terminal 5 in the call (hereinafter referred to as the calling terminal) (step ST3).
1). In response to this, the terminal position search unit 154 searches the position registration memory 171 for the position registration information of the terminal during the call,
If there is corresponding location registration information, the location registration information is given to the call control unit 153.

The call control unit 153 has a terminal position searching unit 154.
The wireless zone in which the busy terminal is present is determined based on the response from, and the communication setting search unit 155 is caused to search for the communication setting relating to the wireless zone (step ST3).
2). In response to this, the communication setting search unit 155 searches the communication setting memory 172 using the identification number of the wireless zone indicated in the location registration information of the called terminal as a key, and the call control unit 153 stores the communication setting obtained thereby. Notice.

The call control unit 153 has a communication setting search unit 155.
Based on the notification from, it is determined whether or not the call is prohibited in the wireless zone where the receiving terminal exists (step ST33). Here, if the call in the wireless zone in which the called terminal exists is permitted, the call control unit 153 ends the call disconnection process without disconnecting the call of the wireless terminal 5. On the other hand, if the call in the wireless zone in which the busy terminal exists is prohibited, the call control unit 1
53 starts the built-in disconnection timer (step S
T34). The disconnect timer has a predetermined grace period (for example, 30 minutes).
Seconds). Then, the call control unit 153
Perform voice message interrupt transmission processing (step ST3)
5). In this voice message interrupt transmission processing, the communication path switch 11 is controlled to further connect the voice announcement device 14 to the link of the terminal in communication, and then, for example, "Call restriction is performed in this wireless zone. Please note that you will be disconnected automatically after a second. "
This is the process of sending from.

After that, the call controller 153 waits for the disconnection timer to internally output the time-out signal (step ST36). Then, when the disconnect timer finishes counting the grace period and outputs the time-out signal, the call control unit 153 disconnects the call of the busy terminal and forcibly ends the call (step ST37).

When the process of step ST37 is completed, the call control section 153 ends the call interruption process. In the case where the call interruption processing is executed in response to the change of the communication setting pattern, the above-mentioned processing is performed for all the wireless terminals 5 in the call at the time of changing the communication setting pattern. I do.

As described above, according to the present embodiment, it is possible to arbitrarily set restrictions on calls made by the wireless terminal 5 for each wireless zone. Therefore, even if you prohibit calls only in some areas where it is not desirable to make calls, such as multi-purpose halls in leisure facilities, even if you make calls in doorways, plazas, play facilities, etc. It is possible to provide a call service in an area where there is no problem.

Further, according to the present embodiment, it is possible to arbitrarily set whether or not the call is prohibited for a single wireless zone, so that whether to permit or prohibit the call is selected according to the usage status of the facility corresponding to the wireless zone. Can be set as desired. Therefore, as described above, in the multipurpose hall, it is possible to perform detailed operations such as prohibiting the call only during the lecture and providing the call service in other periods.

Further, according to the present embodiment, the implementation pattern of call regulation is automatically changed according to the preset pattern schedule information. Therefore, when the time zone during which the call is to be regulated is clear, By setting the pattern schedule information in advance, it is possible to save the administrator's trouble and to properly switch the enforcement / cancellation of the call regulation.

It has the same configuration as the communication control device 1 of the first embodiment, but has a CPU 71, a ROM 72 and a RAM 73 instead of the CPU 15, the ROM 16 and the RAM 17, respectively.

The CPU 71 operates according to the operation program stored in the ROM 72 to control each circuit in the communication control device 7 and realize the operation as the communication control device.

The ROM 72 fixedly stores an operation program of the CPU 71 and data necessary for the CPU 71 to control each circuit in the communication control device 7.

The RAM 73 rewritably stores data necessary for the CPU 71 to control each circuit in the communication control device 7, and is generated when the CPU 71 controls each circuit in the communication control device 7. Store data temporarily. A part of the storage area of the RAM 73 includes a position registration memory 171, a communication setting memory 172, a communication setting pattern recording memory 173, and a maintenance wireless terminal number memory 731.
Is set to That is, the RAM 73 is based on the RAM 17 of the first embodiment and has a new maintenance wireless terminal number memory 731. The maintenance wireless terminal number memory 731 is for storing the identification number of the wireless terminal 5 which is determined to perform the instruction operation for maintenance.

The CPU 71 realizes various functions by operating according to the operation program stored in the ROM 72. FIG. 14 is a functional block diagram schematically showing the relationship of various functions realized by the CPU 71.

As shown in this figure, the functions realized by the CPU 71 include a terminal management unit 151, a terminal position registration unit 152,
There are a terminal position search unit 154, a communication setting search unit 155, a communication setting pattern registration unit 157, a call control unit 711, and a communication setting setting unit 712.

That is, the function realized by the CPU 71 is almost the same as the function realized by the CPU 15 in the first embodiment, but instead of the call control unit 153 and the communication setting setting unit 156, the call control unit 711 and the communication setting setting are performed. Part 7
Each of the 12 functions is realized.

It has a function of instructing the communication setting setting unit 712 to execute the update processing of the communication setting pattern, when a predetermined special number is transmitted from.

The communication setting setting unit 712 has the function of executing the update processing of the communication setting pattern in response to an instruction from the call control unit 711, in addition to the function of the communication setting setting unit 156 in the first embodiment. are doing. Further, the communication setting setting unit 712, when performing the communication setting pattern update process, sets the wireless terminal 5 that has transmitted the special number as the maintenance wireless terminal (hereinafter referred to as the maintenance wireless terminal). Whether or not the maintenance wireless terminal number memory 73
Confirm by referring to 1.

Next, the operation of the communication control device 7 configured as described above will be described.

Call control unit 711 and communication setting setting unit 71
2 similarly executes various kinds of processing executed by the call control unit 153 and the communication setting setting unit 156 in the first embodiment. In addition to this, the call control unit 711 and the communication setting setting unit 712 execute the following processing.

The radio terminal 5 existing in the service area of the communication control device 7 issues a call instruction with a predetermined special number for instructing the update of the communication setting pattern, and a call setting request signal indicating the special number is transmitted. If so, the call setting request signal is received by the wireless base station 3 that can communicate with the wireless terminal 5. This call setup request signal is transmitted to the wireless base station 3
To the CPU 71 via the communication line 4, the base station interface circuit 13 and the bus 19. And CP
In U71, the call control unit 711 executes the setting update processing as shown in FIG. 15 in response to the application of the call setting request signal indicating the special number.

That is, the call control unit 711 first causes the terminal position searching unit 154 to search the position of the wireless terminal 5 (hereinafter, referred to as an instruction terminal) that has transmitted the call setting request signal (step ST41). In response to this, the terminal position search unit 1
Reference numeral 54 indicates the location registration information of the pointing terminal in the location registration memory 17
When the corresponding location registration information is found, the location control information is given to the call control unit 711.

The call control unit 711 has a terminal position searching unit 154.
Based on the response from, it is determined whether the position of the instruction terminal has been registered (step ST42). Here, if the location registration information of the instructing terminal is not given from the terminal location searching section 154, the call control section 711 determines that the instructing terminal has not been location registered. At this time, the call controller 7
11 sends a disconnection instruction signal to the instruction terminal (step ST43), and ends the setting update processing. On the other hand, when the location registration information of the instructing terminal is given from the terminal location searching unit 154, the call control unit 711 determines that the instructing terminal is registered in location. At this time, the call control unit 711 notifies the communication setting setting unit 712 of the position of the instructing terminal, the identification number of the instructing terminal, and the update type of the communication setting pattern (step ST44).

The communication setting setting unit 712 executes the setting updating process as shown in FIG. 15 in response to the notification from the call control unit 711.

That is, the communication setting setting section 712 first searches the maintenance wireless terminal number memory 731 for the identification number of the instruction terminal notified from the call control section 711 (step S).
T51). Then, from the result of this search, the communication setting setting unit 7
12 determines whether or not the instruction terminal is set for maintenance depending on whether or not the corresponding identification number is stored in the maintenance wireless terminal number memory 731 (step ST52). Here, if the instruction terminal is not set for maintenance, the communication setting setting unit 712 invalidates the instruction to update the communication setting pattern this time, and notifies the call control unit 711 of refusal (step ST53). The setting update process ends. On the other hand, if the instruction terminal is set for maintenance, the communication setting setting unit 712 executes the setting update process (step ST54).

The setting update process is a process of updating the communication setting pattern stored in the communication setting memory 172 in response to the update instruction. There are two methods for updating this communication setting pattern, one is for updating in units of zones,
The other is switching of communication setting patterns. Furthermore, the former has two types of processing, that is, prohibition setting and cancellation of prohibition, and the latter has two types of processing, switching and cancellation. For each of these processes, different special numbers are set as follows, for example.

Special number "123-1": Calls are prohibited in the wireless zone to which the current location of the administrator belongs.

Special number "123-2": Releases the prohibition of calls in the wireless zone to which the current position of the administrator belongs.

Special number "124-1": The communication setting pattern is switched to another pattern.

Special number "124-2": Return to the pattern indicated by the pattern schedule information.

Therefore, in the setting update processing, the communication setting setting unit 712 causes the special number "123-1" or the special number "123".
If "-2" is specified, the communication setting pattern stored in the communication setting memory 172 is updated so that only the setting relating to the wireless zone corresponding to the position of the instruction terminal is prohibited or permitted. Further, the communication setting setting unit 712 uses the special number “124-1” in the setting update process.
Is designated, the communication setting pattern stored in the communication setting pattern recording memory 173, which is different from the communication setting pattern currently stored in the communication setting memory 172, is read out, and the communication setting memory 172 is read. To memorize. In addition, in the setting update processing, the communication setting setting unit 712 indicates the pattern schedule information among the communication setting patterns stored in the communication setting pattern recording memory 173 when the special number “124-2” is designated. The communication setting pattern to be read is read out and stored in the communication setting memory 172.

When the setting update processing as described above is completed,
The communication setting setting unit 712 notifies the call control unit 711 of completion (step ST55), and ends the setting update process.

The call control section 711 then proceeds to step ST44.
After the notification in (1), the communication setting setting unit 712 waits for a rejection notification or a completion notification (steps ST45 and ST46). Therefore, when the communication setting setting unit 712 gives a rejection notification as described above, the call control unit 711 sends a disconnection instruction signal to the instructing terminal in step ST43, and the setting updating process ends therewith. Further, when the completion notification is given from the communication setting setting unit 712 as described above, the call control unit 711 performs a voice message sending process (step ST47), and then ends the setting updating process. The voice message sending process is performed by the voice announcement device 14 with respect to the instruction terminal.
Is a process for transmitting the following voice message from the voice announcement device 14 for notifying the contents of the setting update process performed by the communication setting setting unit 712 after connecting the.

When the special number "123-1" is specified:
"Start regulation" When special number "123-2" is specified: "Cancel regulation" When special number "124-1" is specified: "Regulation pattern from pattern 1 (2) to pattern 2" When the special number "124-2" is specified: "The change is canceled." Thus, according to the present embodiment, the enforcement status of the regulation according to the instruction from the wireless terminal 5. Can be changed. As a result, for example, when it is desired to restrict the call only during the period of the event that is irregularly held, the staff at the venue can wait for the start timing and the end timing of the event to determine the communication setting pattern from the wireless terminal 5. By instructing the update, it becomes possible to appropriately regulate the call. That is, it is possible to flexibly operate according to the actual situation of the facility.

Further, according to the present embodiment, the communication setting pattern is updated only in response to the instruction from the wireless terminal 5 set for maintenance, so that the update of the communication setting pattern can be designated. Even if a general user erroneously sends a special number, it is possible to prevent the communication setting pattern from being updated in response to this.

(Third Embodiment) FIG. 16 is a block diagram showing the arrangement of a communication control apparatus according to this embodiment. The same parts as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this figure, the reference numeral 8 is a communication control device. This communication control device 8 has a plurality of (m
It is connected to the stations (not shown) of the communication network via the station line 2 (2-1 to 2-m) of this book) and is distributed and arranged in a predetermined service area (for example, in a specific facility). Multiple (n)
Wireless base stations 3 (3-1 to 3-n) of communication channels 4 (4-
1 to 4-n). Then, the communication control device 8 is provided with a plurality of wireless terminals 5 (5-1 to 5) such as cordless telephones located in respective communication areas of the wireless base station 3.
5-p), and if necessary, call control between the wireless terminals 5 or between the terminals connected via the central line 2 and the wireless terminals 5 is performed.

The wireless base station 3 and the wireless terminal 5 are connected via a wireless channel. This wireless channel access system is a 4-channel multi-carrier TD.
MA (Time Division Multiple Access) -TDD (Time
Division Duplex) method is used.

Now, the communication control device 8 has the communication path switch 1
1, a plurality (m) of station line interface circuits 12 (12-1
~ 12-m), multiple (n) base station interface circuits 1
3 (13-1 to 13-n), voice announcement device 14, RAM1
7, maintenance terminal interface circuit 18, CPU 81 and ROM 82. Each of these parts
Are connected to each other. Station line interface circuits 12-1 to 12-m, base station interface circuits 13-1 to 13
-n and the voice announcement device 14 are each connected to the communication path switch 11.

That is, the communication control device 8 of this embodiment is
It has the same configuration as the communication control device 1 of the first embodiment, but instead of the CPU 15 and the ROM 16, a CPU 81
And a ROM 82, respectively.

The CPU 81 controls each circuit in the communication control device 8 by operating according to the operation program stored in the ROM 82, and realizes the operation as the communication control device.

The ROM 82 fixedly stores an operation program of the CPU 81 and data necessary for the CPU 81 to control each circuit in the communication control device 8.

The CPU 81 realizes various functions by operating according to the operation program stored in the ROM 82. FIG. 17 is a functional block diagram schematically showing the relationship of various functions realized by the CPU 81.

As shown in this figure, the functions realized by the CPU 81 include a terminal management unit 151, a terminal position registration unit 152,
There are a terminal position search unit 154, a communication setting search unit 155, a communication setting setting unit 156, a communication setting pattern registration unit 157, a call control unit 811, and a wireless control unit 812.

That is, the function realized by the CPU 81 is almost the same as the function realized by the CPU 15 in the first embodiment, but the call control unit 811 is realized instead of the call control unit 153, and the wireless control unit 812 is realized. Has been added.

[0115] The call control unit 811 performs the same process as the call control unit 153, but also performs a process for notifying the wireless terminal 5 of the restricted state to the restricted state. The wireless control unit 812 uses the system information notification message transmitted by the wireless base station 3 to
Processing for notifying the wireless terminal 5 of the regulation state is performed.

Next, the operation of the communication control unit 8 configured as above will be described.

In the main control section 81 of this embodiment, the first control unit 81
Various processes executed by the main control unit 15 in the embodiment are executed in substantially the same manner. In addition to this, in the main control unit 81,
The wireless control unit 812 executes the following processing.

That is, the wireless control unit 812 receives the communication setting completion signal generated by the communication setting setting unit 156 when the communication setting setting unit 156 completes the communication setting pattern changing process, and then, FIG. The notification message change process as shown in is executed.

When the notification message change process is started, the radio control section 812 first searches for a radio zone in which the setting of permission / prohibition of a call is changed due to the change of the communication setting pattern (step ST61), and the corresponding radio It is determined whether or not there is a zone (step ST62).

Here, when one corresponding wireless zone is found, the wireless control section 812 searches the communication setting memory 172 for the communication setting of the wireless zone (step ST6).
3). Then, the system information notification message is edited according to the result of this search (step ST64). Editing of this system information notification message means that the information indicating whether or not the wireless base station can be used (whether or not the zone can be selected) in the system information notification message is set to the permitted state if the call is permitted, or the call is prohibited. If so, it is a process of setting each to the prohibited state.

Then, the radio control unit 812 gives the edited system information notification message to all the radio base stations 3 in the corresponding radio zone, and requests switching of the system information notification message (step ST65).

After this, the wireless control section 812 determines the step S
Until it is determined that there is no applicable wireless zone at T62,
The processing of steps ST61 to ST65 is repeated. As a result, the system information notification message is switched for all the wireless zones whose call permission / denial settings have been changed. Then, if the wireless control unit 812 determines that there is no wireless zone corresponding to all the wireless zones in which the setting of the permission / prohibition of the call is changed, and the corresponding wireless zone does not exist in step ST62, the notification message change process is ended with this. To do.

The radio base station 3 periodically sends out the system information notification message. When the communication control device requests the switching of the system information notification message as described above, the system given there will be used thereafter. Sends an information notification message.

The wireless terminal 5 receives the system information notification message periodically sent from the wireless base station 3 in the standby state, and is located outside the service area when the system information notification message cannot be received. It is determined that there is an out-of-range display.

When the system information notification message can be received, the base station information is checked. This base station information includes designation of availability of the wireless base station 3, whether it is a specific user service station / non-specific user service station, or priority station / general station. Therefore, the wireless terminal 5 can perform communication by using the wireless base station 3 that is transmitting the base station information by checking whether or not the wireless terminal 5 conforms to the designation in the base station information. Determine if it is possible. Then, if it is determined that communication cannot be performed, the wireless terminal 5 also performs the out-of-range display.

Therefore, as described above, by controlling the information indicating whether or not the wireless base station can be used according to whether or not the call is permitted, the wireless terminal 5 located in the wireless zone in which the call is prohibited can display the out-of-range display. it can.

On the other hand, since the wireless terminal 5 in the call does not receive the system information notification message, the wireless terminal 5 in the call cannot display the out-of-range display by the above means.

However, for the wireless terminal 5 during a call, the control channel (FACCH, SACC) on the communication channel is
H) can be used to provide the base station information in the zone information notification message.

Therefore, the call control unit 811 performs the call interruption process almost in the same manner as in the first embodiment, except that the disconnection timer is activated in step ST34 as shown in FIG. Is edited and transmitted (step ST71). At this time, the call control unit 811
Sets the information indicating the availability of the wireless base station in the zone information notification message to the prohibited state, and gives it to the wireless terminal 5 using the control channel on the communication channel. This causes the wireless terminal 5 in the call to display the out-of-range display.

As described above, according to the present embodiment, the terminal for which a call is prohibited is caused to perform the out-of-range display, so that the user can be informed that the call cannot be made. Moreover, in the present embodiment, the out-of-service display function of the general wireless terminal 5 is used, so that it is not necessary to give the wireless terminal 5 a special function, and the versatility is high.

The present invention is not limited to the above embodiments, and various modifications such as the following are possible.

It is assumed that the communication setting pattern set in the communication setting memory 172 is such that the restriction contents are set according to the call type (here, outgoing, incoming, talking, and handover) as shown in FIG. It may be configured such that whether or not to permit a call is different for each type. That is, for example, in the wireless zone named “Z-2” in FIG. 20,
Calls due to new incoming / outgoing calls are prohibited, but if there is a call during the setting of the communication setting pattern or if you move to the wireless zone while making a call, you should continue the call. Tolerate. The call types are shown in Figure 2.
The number is not limited to four shown in 0 and may be arbitrary.

As for the communication setting pattern set in the communication setting memory 172, for example, as shown in FIG. 21, the regulation contents are set according to the type of the wireless terminal 5 (here, telephone terminal and information terminal). It may be configured such that whether or not to permit a call is different for each type. That is, for example, in the wireless zone named “Z-3” in FIG. 21,
Calls are prohibited for telephone terminals regardless of call type, but calls for new incoming / outgoing calls are prohibited for information terminals, but if there was a call during the setting of the communication setting pattern, or a call was made. When the user moves to the wireless zone without change, the call is allowed to continue. The type of the wireless terminal 5 is not limited to the two shown in FIG. 21, and may be arbitrary. In addition, in FIG. 21, the call permission / prohibition is set according to both the type of the wireless terminal 5 and the call type, but the call permission / prohibition may be set only according to the type of the wireless terminal 5.

In the first embodiment, any one of a plurality of communication setting patterns registered in advance is automatically selected and used according to the time zone. May be changed according to an instruction from the maintenance worker. This is achieved by, for example, causing the communication setting unit 156 to set a designated one of the communication setting patterns in the communication setting memory 172 in response to an instruction to change the communication setting pattern to be used. It Alternatively, the communication setting pattern recording memory 173 and the communication setting setting unit 156 are eliminated, and the communication pattern registration unit 157 causes the communication setting pattern memory 172 to operate.
This is achieved by directly updating the communication setting pattern stored in.

In each of the above-mentioned embodiments, when the call processing corresponding to the call request is not performed, the voice message is sent to the request source, but the sending of the voice message is not essential. Also, instead of a voice message, a busy tone may be sent.

In each of the above-mentioned embodiments, the wireless terminal 5 in the call is changed by changing the communication setting pattern and performing the handover process.
If a situation occurs where a call is placed in a prohibited wireless zone, the call shall be disconnected after the grace period has elapsed, but immediately without waiting for the grace period to elapse. The call may be disconnected. Further, if the call in the wireless zone in which the handover request is made is prohibited, the handover itself may be rejected.

For some of the wireless terminals 5 registered in advance, the call may be always permitted regardless of the communication setting pattern. As a result, it is possible to perform flexible operation, for example, to enable telephone calls only to employees of facilities where service zones are formed.

In the second embodiment, the update instruction of the communication setting pattern is accepted by the special number.
The wireless terminal 5 may be provided with a function of transmitting a special signal for instructing to update the communication setting pattern, and the signal may be used to receive the instruction to update the communication setting pattern.

In the third embodiment, the out-of-service display function of a general wireless terminal is diverted to display the call refusal state. However, the call refusal state is notified. A special signal may be set to notify the wireless terminal 5 of the call rejection state by this signal, and the wireless terminal 5 may display the call rejection state separately from the out-of-range display.

[0140]

According to the present invention, for each communication area unit in charge of each of a plurality of wireless base stations or each of predetermined wireless zones in which a plurality of the communication areas are collectively set, the wireless base stations are located in the wireless zone. Communication permission / denial information storage means for storing communication permission / denial information indicating whether or not to permit communication by a wireless terminal, and when a call request related to a wireless terminal located within a predetermined service area occurs, the call request Is determined based on the communication permission / denial information stored in the communication permission / denial information storage means, and whether or not communication is permitted in the wireless zone in which the wireless terminal associated with the call is permitted. The call processing according to the request is executed, and when the communication permission / denial information stored in the communication permission / denial information storage means is changed, the communication permission / denial information after the change is used. Since there is a call processing means for disconnecting a call relating to a wireless terminal in communication when the wireless terminal is in communication located in the prohibited wireless zone, it is possible to change the service according to the situation of the service area of the mobile communication service. It becomes a communication control device that can limit the call.
