DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system accommodating a radio base station and communicating with a mobile station device such as a PHS telephone or a portable telephone, for example, a PHS (Person).
The present invention relates to a voice call restriction method for restricting a voice call by restricting voice transmission or reception in an al Handy-phone System) system, and a mobile communication system, a mobile communication exchange, and a mobile station device to which the method is applied.

[0002]

2. Description of the Related Art PHS telephones and mobile telephones are known as mobile station devices (hereinafter abbreviated as mobile stations) for performing mobile communication. Regarding the standardization of interfaces related to the two basic technologies constituting the PHS, that is, the radio system technology and the network technology, the method of using radio waves is defined as described in "Easy Personal Handy Phone" (Telecommunications Association). For the air interface to
The radio wave system development center (RCR) has been studying. In December 1993, RCR STD-28 (2nd generation cordless telephone system standard first edition) was introduced, and the interface between public base stations and digital networks was established. The telecommunications technical committee (TTC) has been examining the network interface that defines the standard, and in November 1993, JT-Q921-b (Simplified mobile phone system between the public base station and the digital network) Interface-Layer 2 specification)
And JT-Q931-b (simplified mobile phone system public base station-digital network interface-layer 3 specification) were respectively established as standards.

[0003] RC which is a standard of air interface
Since the RSTD-28 provides a voice communication service, only voice is initially defined in the network interface, but standardization of a non-telephone service enabling data communication has been promoted.
In November 1995, the provisions of JT-Q921-b were added so that data communication with a personal computer or the like could be performed by a PHS via a modem.

In the PHS, an area (wireless zone) covered by one wireless base station has a radius of 100 m or more in order to increase the unit area capacity by repeatedly using frequencies.
A micro cell zone configuration reduced to about 300 m is employed. In addition, the range that one radio base station can cover greatly depends on the location where the radio base station is installed, the shape and characteristics of the antenna used, the required transmission power, and the like. The design has been made. Therefore, provision of a very detailed service area can be realized by the micro cell zone configuration.

[0005]

By the way, the voice call by the PHS may inconvenience the surrounding people.
Hospitals, hotels, libraries, etc. prohibit making and receiving calls. Specifically, making and receiving calls is prohibited by not installing wireless base stations in places such as libraries and hotel lobbies. However, recently, due to the spread of portable information terminals, P
Opportunities for performing data communication by HS are increasing. In this data communication by PHS, no voice is generated,
The effect on surrounding people is small.

[0006] However, when the outgoing / incoming call by the PHS in the library or the like is uniformly prohibited as described above, persons in the area cannot perform data communication even though there is little influence on surrounding people. There is a problem.

On the other hand, in a mobile phone system, which is a type of mobile communication, an area (wireless zone) covered by one wireless base station has a radius of several hundred meters to several kilometers.
It covers a relatively large area, and mobile satellite communication using satellites covers a very large area with a radius of several hundred to several thousand kilometers. Within the area covered by these one radio base station or satellite, there are libraries, concert halls, trains, etc.
There are many places where voice communication can bother others. Therefore, in such places PH
As in the case of S, self-control of voice communication is required.

However, unlike the PHS in the portable telephone system, a specific place cannot be uniformly set as a call-inhibited area because the wireless zone is wide. For this reason, the user must rely on the user's own awareness of intentionally turning off the power of the mobile phone. However, the current situation is that the rules are not always followed, and even if the called party does not intend to use it, the mobile phone must be turned off before it can be used anywhere. I will receive a call. Therefore, there is a strong demand for a system that can reliably prohibit voice calls in places such as libraries. At the same time, since data communication has little effect on surrounding people, it is desired to realize a system that allows only data communication and prohibits only voice communication.

The present invention has been made to solve such a problem, and an object of the present invention is to restrict outgoing and incoming calls in the case of voice communication, but to allow mobile phones to send and receive incoming calls in the case of data communication. It is an object of the present invention to provide an outgoing call control method and an incoming call control method in a switching system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on the illustrated embodiments.

[First Embodiment] FIG. 1 shows a first embodiment of the present invention.
FIG. 2 is a diagram showing a block configuration of a PHS communication system showing the embodiment of FIG.

The PHS communication system of the present embodiment has a PH
S exchange 101, a plurality of PHS terminals 112, and their P
It comprises a radio base station 111 serving as a relay point between the HS terminal 112 and the PHS exchange 101, and a radio base station information management unit 110 for managing information on the radio base station 111. PH
The S terminal 112 is equivalent to a mobile station that communicates via a wireless communication line under the control of the PHS exchange 101, and in addition to a PHS telephone that can only perform voice communication, a cable is connected to the PHS telephone to enable data communication. It includes an information terminal and a portable or non-portable information terminal having a function of performing data communication using a PHS line.

The PHS exchange 101 has a location information storage unit 1
02, location information registration / reference section 103, voice transmission / reception identification section 104, voice transmission / reception non-permitted talkie transmission section 105, radio base station information registration section 106, radio base station information storage section 107,
It comprises a wireless base station information reference section 108 and a PHS control section 109. In FIG. 1, other functions of the PHS exchange not directly related to the present invention are not described in the block diagram.

FIG. 2 shows a data structure of the position information 1021 stored in the position information storage unit 102. Location information 10
21 is a PHS terminal number 201 uniquely assigned to the PHS terminal 112, and each PHS terminal number is used as a key.
Radio base station 1 used by terminal 112 to perform location registration
11 is a radio base station number uniquely assigned to the radio base station 111, and a location registration radio base station number 2
02 is a data configuration to be extracted.

FIG. 3 shows a data structure of the radio base station information 1071 stored in the radio base station information storage section 107.
The wireless base station information 1071 extracts, using the wireless base station number 301 as a key, voice transmission / reception permission display information 302 indicating whether or not voice transmission from the corresponding radio base station and voice reception to the relevant radio base station are permitted. This is the data configuration to be performed.

In the radio base station information 1071, the voice transmission / reception permission display information 302 corresponding to the radio base station number 301 is registered from the radio base station information management unit 110 via the radio base station information registration unit 106 of the PHS exchange 101. .

The position information 1021 in FIG. 2 is accessed from the position information registration / reference unit 103 by a conventional technique.

FIG. 4 is a flowchart for explaining the processing from the transmission of the PHS terminal 112 to the reception of the PHS terminal.

First, when the PHS terminal 112 makes a call (step 401), the call setting message 402 is transmitted via the radio base station 111 to the PHS controller 1 of the PHS exchange 101.
09 is notified. In the PHS control unit 109, a procedure such as authentication of the PHS terminal 112 according to the related art is performed.
A call setting acceptance message 403 is returned to the calling PHS terminal 112.

Next, the radio base station number of the radio base station 111 that relayed the call setting message 402 is notified to the radio base station information reference section 108, and the voice transmission / reception permission display information 302 of the originating radio base station is transmitted. It is extracted (step 404), and it is determined whether or not voice transmission is permitted (step 405). If it is determined in step 405 that the voice transmission is not permitted, the voice transmission / reception identification unit 104 is requested to execute the voice transmission / reception identification process (FIG. 5) (step 406), and the transmission PHS terminal 401 is activated by voice. A distinction is made as to whether a call was made or a non-voice call was made.

In the voice transmission / reception identification process 501 shown in FIG. 5, "information transmission capability" is extracted from the "transmission capability" information element of the call setting message (step 502), and the extracted information transmission capability is "unrestricted digital". It is determined whether or not this is the case (step 503). If the determination result in step 503 is NO
(That is, the information transmission ability is not "unrestricted digital")
In the case of, the information transmission capacity is "3.1Khz audio"
(Step 504), and in the case of YES (if the information transmission capability is “3.1 Khz audio”), it is determined whether or not the “higher layer compatibility” information element of the call setup message exists (step 504). In step 505), when there is an information element, "high layer characteristic identification" is extracted from the "high layer compatibility" information element of the call setup message (step 506).

It is determined whether or not the higher layer characteristic identification extracted in step 506 is "telephone" (step 507).
If NO (not "telephone"), "non-voice" is returned to PHS control section 109 (step 508). Step 50
If the result of the determination in step 3 is YES (the information transmission capability is "unrestricted digital"), step 508 is executed and "non-voice" is returned to the PHS control unit 109. If the determination result of step 504 is NO (the information transmission capability is “3.1 Kh
If it is not “z audio”), if the result of determination in step 505 is no information element, and if the result of determination in step 507 is YES (“telephone”), “voice” is returned to the PHS control unit 109 (step 509). ).

The PHS control unit 109 determines the identification result of the voice transmission / reception identification processing 501 (step 407). If the identification result is “voice”, the voice transmission / reception non-permissible talkie transmission unit 105 is disabled. It instructs transmission of the allowable talkie (step 408), and transmits a disconnection message having a reason indicating that the talkie can be used to the calling PHS terminal 112 (step 409).

Thus, the originating PHS terminal 112
When a talk is heard from the PHS exchange 101 indicating that voice transmission from the corresponding radio base station 111 cannot be performed (step 410), the calling PHS terminal 112 is prompted to disconnect.

When the originating PHS terminal 112 is disconnected (step 411), a release message is notified from the originating PHS terminal to the PHS control unit 109 via the radio base station 111 (step 412).

Upon receiving the release message 412, the PHS control unit 109 stops the transmission of the voice transmission non-permissible talkie whose transmission has been started in step 408 (step 41).
3) Return a release completion message to the transmitting PHS terminal 112 (step 414).

If the voice transmission permission determination result in step 405 is acceptable, voice transmission / incoming identification processing 501 is performed on voice transmission / incoming identification section 104 (step 415), and outgoing PHS terminal 112 performs voice transmission. Or whether a non-voice call was made.

Next, using the incoming PHS terminal number set in the call setting message 402 as key information, the location information registering / referencing section 103 is notified of the location of the incoming PHS terminal registered in the location information storage section 102. Registered wireless base station number 2
02 (Step 416), and instructs the wireless base station information reference unit 108 to extract the extracted voice transmission / reception permit display information 302 of the called wireless base station (Step 4).
17), the extracted voice transmission / reception permitted display information 302 is determined (step 418).

If the result of the determination at step 418 is that voice incoming / outgoing is not permitted, the voice transmitting / receiving incoming call discrimination result performed in step 415 is determined (step 419). 105 is instructed to transmit a voice call non-permissible talkie (step 420),
A disconnection message having a reason indicating that the talkie can be used is transmitted to the calling PHS terminal 112 (step 409).

Thus, the originating PHS terminal 112
The wireless base station where the terminating PHS terminal is located hears a talk from the PHS exchange 101 indicating that speech reception is not possible (step 410), and the calling PHS terminal is prompted to disconnect 411.

If it is determined in step 407 that the outgoing PHS terminal is outgoing by non-voice, or step 418
It is determined whether or not the wireless base station in which the incoming PHS terminal is located allows the incoming call by voice.
If it is determined that the HS terminal has made a non-voice call, a normal connection operation according to the related art is performed (step 421).

As described above, according to the present embodiment, since the information on whether or not the transmission and reception by voice is permitted is managed by the PHS exchange for each radio base station, the PHS terminal uses the information for transmission. If the wireless base station does not allow voice transmission and the caller makes a voice call, the voice call is sent by notifying the caller that the voice transmission is not allowed as a talkie Is regulated.

Also, at the time of an incoming call to the PHS terminal, if the wireless base station with which the destination PHS terminal performs position registration does not permit incoming by voice, the originating PHS terminal performs voice transmission. If a voice call is made, the PHS terminal of the callee notifies the caller of the fact that the PHS terminal is in a wireless base station that does not allow voice call by talking to the caller. Incoming calls are regulated.

[0045] This makes it possible to regulate both outgoing and incoming calls or both outgoing and incoming calls by voice for each radio base station, and to control the PHS terminal by voice in a place where voice communication causes annoyance to surrounding people. Restrict use,
Flexible operation of the PHS communication system, such as allowing only data communication, becomes possible. Specifically, for example, by setting “non-permissible” as a voice transmission / reception permission display to a radio base station covering the location where the library is located, transmission / reception by voice is restricted, but data communication is not permitted. Operation that is possible.

Note that, even if the call is urged to be disconnected by an unacceptable voice call, if the caller does not perform the disconnection operation after a predetermined time has elapsed, the PHS exchange side forcibly performs the disconnection operation. It may be performed. As a result, the effect of restricting the voice call in the non-voice call permitted area is ensured.

The radio base station individual information 8001 is, like the radio base station information 1071 shown in the first embodiment, a radio base station number 301 uniquely assigned to the radio base station 111 and used as a key. Nos. 801, 804, 807, 810, and 813, and voice transmission / reception permission display information 80 indicating whether voice transmission from the radio base station and voice reception to the radio base station are permitted.
2, 805, 808, 811 and 814 are extracted.

Further, area X accommodation radio base station information 901
The 1 and area Y accommodation radio base station information 9041 is information for managing the number of radio base stations accommodated in the area and the radio base station numbers accommodated in each area.

In order to specifically explain the second embodiment shown in FIG. 6, radio base station individual information 8001 in FIG.
“X” is indicated in the area number 801 of the wireless base station (A) 111A, and “permissible” is indicated in the voice transmission / reception permitted display information 802.
The area number 804 of the wireless base station (B) 111B is “X”, and the voice transmission / reception permission display information 805 is “non-permission”.

Is the area number 813 of the wireless base station (E) 111E.
Is set to “Y”, and “allowed” is set to the voice transmission / reception allowed display information 814.

Also, area X accommodation radio base station information 901
1 is “2” for the number 902 of wireless base stations in the area, and the wireless base station = A and the wireless base station = B
Is set in the area Y accommodation radio base station information 9041, "3" is set in the number 902 of radio base stations in the area, the radio base station = C is set in the accommodation radio base station number 903, the radio base station = D, and the radio base station = E. Are set respectively.

Under the conditions of FIG. 7, FIG. 8 and FIG.
The operation in the case where the terminal 112X makes a call using the wireless base station (A) 111A and the called PHS terminal 112Y of the other party exists in the location registration area Y will be described with reference to FIG. In FIG. 10, the same parts as those in the first embodiment shown in FIG. 4 are described using the same numbers as those in FIG. 4, and the description is partially omitted.

First, when the calling PHS terminal 112X makes a call (step 401), the call setting message 402
The PHS control unit 109 of the S exchange 101 is notified, and a call setting acceptance message 403 is returned to the calling PHS terminal 112X. Next, the radio base station number (A) of the radio base station (A) 111A that relayed the call setting message 402 is notified to the radio base station information reference unit 108, and the voice of the originating radio base station (A) 111A is transmitted. The transmission / reception permission display information 802 is extracted (step 1001), and it is determined whether or not the voice transmission is permitted (step 405).

If it is determined in step 405 that the voice transmission is not permitted, the voice transmission / reception identification unit 104 is requested to execute the voice transmission / reception identification processing 501 (FIG. 5) (step 406). Whether the PHS terminal 112X has made a voice call or a non-voice call is identified.

Next, the PHS control section 109 judges the identification result of the voice transmission / reception identification processing 501 (step 40).
7), if the identification result is voice, the voice transmission / reception non-permitted talkie transmitting unit 105 is instructed to transmit a voice transmission non-permitted voice (step 408), and the reason that the voice can be used for the transmission PHS terminal 112X. A disconnect message having the indication is transmitted (step 409).

As a result, the transmitting PHS terminal 112X hears the talk from the PHS exchange 101 that the voice cannot be transmitted from the corresponding radio base station (A) 111A (step 410), and prompts the transmitting PHS terminal 112X to disconnect. It is.

If the voice transmission permission determination result in step 405 is acceptable, the voice transmission / reception identification unit 104 is requested to execute the voice transmission / reception identification processing 501 (step 41).
5) Identify whether the calling PHS terminal 112X has made a voice call or a non-voice call.

Next, using the incoming PHS terminal number 201 set in the call setup message 402 as key information, the location information registration / reference section 103 determines the location of the incoming PHS terminal 112Y registered in the location information 6011. The registration area number 702 is extracted. In this example, the area "Y" is extracted (step 1002), and "OFF" is set in the call display (step 1003). As will be described later, this call display is a display used to determine whether or not the incoming PHS terminal sends a talkie indicating that the incoming PHS terminal is not in the location registration area where voice reception is permitted.

Next, the wireless base station information reference unit 108 is instructed to extract the number 902 of wireless base stations in the area accommodated in the extracted location registration area Y (step 100).
4). In this example, the area Y accommodation radio base station information 9041
, "3" is extracted as the number 902 of wireless base stations in the area, and the following processing is repeated for three wireless base stations (step 1005).

First, area Y accommodation radio base station information 904
"C" as the first accommodated wireless base station number 903
Is extracted (step 1006), “permitted” is extracted from the radio base station individual information 8001 as the voice transmission / reception permission display information 808 of the radio base station (C) 111C (step 1007), and it is determined whether the voice reception is permitted. (Step 10
08), which is “permissible”, the radio base station (C) 11
A call setting message for calling the incoming PHS terminal 112Y is transmitted to 1C (step 1010), "ON" is set in the call display (step 1011), and the process returns to step 1005.

Next, area Y accommodation radio base station information 904
“D” as the first and second accommodation radio base station number 903
Is extracted (step 1006), and “non-permissible” is extracted from the radio base station individual information 8001 as voice transmission / reception permission display information 811 of the radio base station (D) 111D (step 1007). Judgment (Step 1
008), it is “non-permissible”, so the result of the voice transmission / reception identification processing 501 performed in step 415 is determined (step 1009). If it is determined that the voice is transmitted, the radio base station (D) 111D The process returns to the step 1005 without transmitting the call setting message to.

Finally, the area Y accommodation radio base station information 90
“E” is extracted as the third accommodated wireless base station number 903 from 41 (step 1006), and “allowed” is used as the voice transmission / reception allowed display information 814 of the wireless base station (E) 111E from the wireless base station individual information 8001. Is extracted (step 1007), and it is determined whether or not the voice incoming call is permitted (step 1008). Since it is "permitted", a call setup message for calling the called PHS terminal 112Y to the radio base station (E) 111E is obtained. Is transmitted (step 10).
12), and set "ON" in the call display (step 101).
1) Return to step 1005.

In step 1005, the repetition processing for the number of radio base stations accommodated in the area is completed, and the call display is determined (step 1013). In this example, a call is made to the radio base station (C) 111C and the radio base station (E) 111E (step 1010, step 101).
2) Since the call display is “ON” in step 1011, the process shifts to a call in the prior art (step 10).
16).

Radio base station individual information 8001 shown in FIG.
However, if not only the radio base station (D) 111D but also the radio base station (C) 111C and the radio base station (E) 111E are set to "non-permissible", the call will be made. The process of step 1011 for setting "ON" in the display is not performed, the process of "OFF" is selected in the determination of the call display in step 1013, a voice call non-permitted talkie is transmitted (step 420), and the calling PHS terminal 112
A disconnect message is transmitted to X with a reason indicating that the talkie can be used (step 409).

As a result, in the transmitting PHS terminal 112X, since there is no radio base station that allows voice reception in the location registration area where the reception PHS terminal 112Y is located, the PHS exchange 1 cannot perform voice reception.
01 hears the toki from step (step 410), call P
The disconnection is prompted to the HS terminal 112X.

If it is determined in step 407 that the outgoing PHS terminal is outgoing by non-voice, a normal connection operation according to the prior art is performed (step 421).

As described above, according to this embodiment, similarly to the above-described first embodiment, information as to whether or not voice transmission and reception is permitted is managed by the PHS exchange for each radio base station. Therefore, if the wireless base station used by the PHS terminal for calling is not allowed to make a voice call, and if the caller makes a call using voice, the voice call is not allowed. By notifying the caller, transmission by voice is regulated.

When a call is received by the PHS terminal from a plurality of radio base stations accommodated in the location registration area in which the location registration is performed by the destination PHS terminal, the incoming call by voice is allowed. When a called PHS terminal is called from a wireless base station that does not have a call, it is determined whether or not the calling PHS terminal has made a voice call. By calling the incoming PHS terminal only from the wireless base station that is permitted to receive voice calls without calling from the station, incoming calls using wireless base stations that are not permitted to receive voice calls are described. Is done.

When all of the plurality of radio base stations accommodated in the location registration area are not allowed to receive a voice call, the destination PHS terminal is set to a radio base station which does not permit a voice call. By notifying the caller of the presence as a talk, the incoming call by voice is regulated.

As a result, it is possible to regulate outgoing and incoming calls or both incoming and outgoing calls by voice for each radio base station, and to control the PHS terminal by voice in a place where voice communication may cause trouble to surrounding people. Restrict use,
Flexible operation of the PHS communication system, such as allowing only data communication, becomes possible. Specifically, for example, by setting “non-permissible” as a voice transmission / reception permission display to a radio base station covering the location where the library is located, transmission / reception by voice is restricted, but data communication is not permitted. Operation that is possible.

[0074] Even if the call is urged to be disconnected by an unacceptable talk of voice communication, if the caller does not perform the disconnection operation after a predetermined time has elapsed, the PHS exchange side forcibly performs the disconnection operation. It may be performed. As a result, the effect of restricting the voice call in the non-voice call permitted area is ensured.

[Third Embodiment] FIG. 11 shows an outgoing PHS
FIG. 11 is a diagram illustrating a configuration of a PHS communication system according to a third embodiment to which the present invention is applied when the terminal and the terminating PHS terminal are connected to different PHS exchanges. Note that FIG.

Before transmitting the PHS 02, the PHS service control apparatus 1101 in the originating PHS exchange 101A inquires the PHS service control device 1101 for information (step 1301).
It is possible to determine whether or not the radio base station 111B in which the terminal 112B is located permits incoming calls by voice.

In the first, second, and third embodiments,
When the called party is in the voice non-acceptance area, an example of transmitting a talkie from the destination PHS exchange indicating that voice reception is not possible (step 410) has been described. A method of connecting to a message recording service center and recording a message that the caller wants to convey may be adopted. This eliminates the need for the caller to make a recall, and can prevent a decrease in service to the caller and the callee due to the restriction on voice communication.

Further, the case where the transmitting terminal is a PHS terminal has been described as an example. Even if the transmitting terminal is an analog terminal or a digital terminal, whether or not PHS receiving by voice shown in the present embodiment is permitted is determined. Needless to say, such control can be realized by using the present invention.

In addition, in the event of a disaster such as an earthquake, storm or flood, the outgoing / incoming call control described in the first, second, and third embodiments is released by the system operation manager performing a predetermined operation in the PHS exchange. Is done. This allows voice calls during a disaster.

FIG. 19 is a flow chart for explaining a process for restricting voice transmission when a mobile station 1401 originates a call in the fourth embodiment.

First, when the originating mobile station 1901 originates a call (step 1902), a call setup message 1903 is notified to the mobile station control unit 1511 of the mobile communication exchange 1501 via the base station 1513. The mobile station control unit 1511 performs a procedure such as authentication of the originating mobile station 1901 according to the related art, and returns a call setting acceptance message 1904 to the originating mobile station 1901.

Next, the base station number of the base station 1513 that has relayed the call setting message 1903 is notified to the base station information reference section 1508, and the voice transmission / reception impossible area presence / absence display information 1702 of the originating base station is extracted. (Step 190
5) It is determined whether or not there is a voice transmission disabled area (step 1906). If it is determined in step 1906 that there is a voice call impossible area, the voice call identification unit 150
4 is requested to execute the voice transmission / reception identification process 2101 (FIG. 21) (step 1907), and it is determined whether the calling mobile station 1901 has made a voice call or a non-voice call.

FIG. 2 shows the processing of the voice transmission / reception identification processing 2101.
1 will be described.

In the voice transmission / reception identification process 2101, “information transmission capability” is extracted from the “transmission capability” information element of the call setting message (step 2102), and the process branches based on the extracted information transmission capability (step 2103). . If it is determined in step 2103 that the information transmission capability is "voice", "voice" is returned to the mobile station control unit 1511 as the identification result (step 2104). In step 2103,
If the information transfer ability is determined to be "unrestricted digital",
“Non-voice” is returned to the mobile station control unit 1511 as the identification result (step 2105). Step 2103
Then, when the information transmission ability is determined to be “voice + data”,
“Non-voice” is returned to the mobile station control unit 1511 as the identification result (step 2106).

In the example shown in FIG. 21, "information transmission capability"
Is determined to be “voice + data”, “non-voice” is returned to the mobile station controller 1511 as the identification result, but “voice” may be used. In addition to the determination of only “information transfer capability”, “lower layer compatibility” or “higher layer compatibility” set in the “access transfer” information element of the call setup message may be further added to the determination. .

The mobile station controller 1511 determines the identification result of the voice transmission / reception identification process 2101 (step 190).
8) If the identification result is "voice", a positioning instruction message is transmitted to the originating mobile station 1901 to collect the location information of the originating mobile station 1901 (step 1909). The originating mobile station 1901 extracts the longitude and latitude as the current position information from the positioning unit 1405 (step 1910), and transmits it as a positioning response message to the mobile communication exchange 1501 (step 1911).

The mobile station control unit 1511 uses the longitude and latitude of the originating mobile station 1901 returned by the positioning response message 1911 as search keys, and uses the search / reception unavailable voice map information 1 as a search key.
5091 is retrieved to extract the voice transmission / reception impossible display information 1803 (step 1912), and the voice transmission / reception impossible display information 1803 is determined (step 1913). If the result of the determination in step 1913 is that “voice transmission / reception is not possible”, the voice transmission / reception non-permissible talkie transmission unit 1505 is sent to the calling mobile station 1901 to notify the calling mobile station 1901 that voice transmission from the corresponding area is not possible. To send a voice call non-permitted talkie (step 1914), and the originating mobile station 1901
A disconnection message having an indication that a talkie can be used is transmitted to the server (step 1915).

As a result, the originating mobile station 1901 hears a talk from the mobile communication exchange 1501 indicating that voice transmission from the corresponding area is not possible (step 191).
6) The calling mobile station 1901 is prompted to disconnect.

When the originating mobile station 1901 is disconnected (step 1917), a release message is notified from the originating mobile station 1901 to the mobile station controller 1511 (step 191).
8). The mobile station controller 1511 sends the release message 19
18, the transmission of the voice-transmitting non-permissible talkie, which has been started in step 1914, is stopped (step 191).
9) Return a release completion message to the originating mobile station 1901 (step 1920).

On the other hand, when the result of the determination of the presence / absence of the voice transmission / reception impossible area in step 1906 is “none”, the receiving side analysis processing shown in FIG. 20 is executed (step 1921). If the identification result of the voice transmission / reception identification process 2101 is determined to be "non-voice" in step 1908, a normal connection operation according to the related art is performed (step 1922). Also,
If it is determined in step 1913 that the calling mobile station 1901 originates from an area where voice transmission is possible, the receiving mobile station 1901 executes the receiving-side analysis processing shown in FIG. 20 (step 1921).

In the example shown in FIG. 19, the originating mobile station 1
901 is a place where voice use is regulated (longitude / latitude)
In the example shown in FIG. 19 (step 1916), the mobile communication exchange 1501 transmits a talkie indicating that voice transmission from the corresponding area cannot be performed (step 1916). Around the current position (longitude / latitude) of, the longitude / latitude at which voice transmission is possible is obtained, and from the obtained longitude / latitude and the longitude / latitude of the caller, the direction and distance of the area where voice transmission is possible The service to the user can be improved by adopting a method of notifying the sender as a talk.

FIG. 20 is a flow chart for explaining a process for restricting the incoming call by voice when the mobile station 1401 receives a call according to the fourth embodiment.

The mobile station control unit 1511 performs location information registration /
For the reference unit 1503, the location registration base station number 1602 (base station 200
7) is extracted from the position information 15021 (step 200).
1) Next, the base station number of the called base station 2007 is notified to the base station information reference unit 1508, and the voice call impossible / unavailable area presence / absence display information 1702 of the called base station 2007 is extracted (step 2002). It is determined whether or not there is (step 2003).

If it is determined in step 2003 that "there is an area where voice call cannot be received", the voice transmission / reception identification unit 150 is determined.
4 is requested to execute the voice transmission / reception identification process 2101 of FIG. 21 (step 2004), and it is determined whether the calling mobile station 1901 has made a voice call or a non-voice call (step 2005). . Here, when the identification result is “voice”, a positioning instruction message is sent to collect the location information of the destination mobile station 2008.
(Step 2006).

The destination mobile station 2008 has its own positioning unit 14.
05, the longitude and the latitude are extracted as the current position information (step 2009) and transmitted to the mobile communication exchange 1501 as a positioning response message (step 201).
0).

The mobile station control unit 1511 uses the longitude and latitude of the destination mobile station 2008 returned by the positioning response message 2010 as a search key, and uses the search / reception map information 1 for voice transmission / reception impossible.
5091 is retrieved to extract the voice transmission / reception impossible display information 1803 (step 2011), and the voice transmission / reception impossible display information 1803 is determined (step 2012). If the result of the determination in step 2012 is “voice outgoing / incoming unavailable”, the destination mobile station 2008 notifies the originating mobile station 1901 that it is located in an area where voice incoming cannot be made. Instruct the non-permissive talkie transmitting unit 1505 to transmit "voice incoming non-permissive talkie" (step 2013), and transmit a disconnection message having a reason indicating that the talkie can be used to the calling mobile station 1901 (step 2014). ).

As a result, the originating mobile station 1901 hears a talk from the mobile communication exchange 1501 that the destination mobile station 2008 is in an area where voice reception is not possible (step 2015), and prompts the originating mobile station 1901 to disconnect. . When the originating mobile station 1901 is disconnected (step 201)
6), a release message is notified from the originating mobile station 1901 to the mobile station control unit 1511 (step 2017).

Upon receiving the release message 2017, the mobile station controller 1511 stops the transmission of the “voice call non-permissible talkie” started in step 2013 (step 2018), and sends a release completion message to the originating mobile station 190.
1 (step 2019).

On the other hand, when the determination result of the voice transmission / reception impossible area presence / absence determination in step 2003 is “none”,
If it is determined in step 005 that the identification result of the voice transmission / reception identification processing 2001 is “non-voice”, and if it is determined in step 2012 that the destination mobile station 2008 is in an area where voice reception is possible, the conventional technology is used. A normal connection operation is performed (Step 2020).

As described above, according to the fourth embodiment, the mobile station is provided with the position detecting means for detecting the current position consisting of the longitude and the latitude, and furthermore, the mobile station covers each radio base station. Voice transmission / reception impossible indicating whether or not there is a specific area where voice communication is not allowed in the wireless area, and voice transmission / reception not specifying the specific area where voice communication is not allowed based on longitude and latitude Display information is provided, and when a call is made from a mobile station, the presence / absence of presence / absence display information of the voice transmission / reception impossible area of the wireless base station used for the call is determined. If the area is indicated, it is determined whether or not the mobile station has made a voice call. If the mobile station has made a voice call, the longitude and latitude of the current position are determined for the mobile station. finger Perform the voice transmission / reception impossible display information from the longitude and the latitude which are the positioning results from the mobile station, and in the case of the area where voice transmission is not possible, it is assumed that voice transmission is not permitted as a talkie. By notifying the originating mobile station, the voice call is regulated.

Further, when an incoming call to the mobile station is made, the presence / absence display information of the voice transmission / reception impossible area presence / absence display information of the base station with which the destination mobile station is performing position registration is determined. If it indicates that there is a voice call impossible area, it is determined whether or not the originating mobile station has made a voice call, and if it has made a voice call, it will be sent to the destination mobile station. It performs a positioning instruction of the longitude and latitude of the current position, and determines the voice transmission / reception impossible display information from the longitude and latitude which are the positioning results from the destination mobile station,
In an area where voice reception is not possible, voice communication is restricted by notifying the calling mobile station that voice reception is not permitted as a talk.

As a result, it is possible to restrict both outgoing and incoming calls and outgoing / incoming calls by voice for each of the preset voice non-callable areas, so that the voice communication may cause trouble to surrounding people. It is possible to flexibly operate a mobile communication system in which use of a mobile station by voice at a place is restricted and only data communication is allowed. Specifically, for example, for a wireless base station that covers the location where the library is located, "voice available / disabled area is present" is set in the voice available / disabled area presence / absence display information of the base station information, and the library is located. For multiple longitudes and latitudes that cover a place, setting the voice-callable / impossible display information in the voice-callable / impossible map information to "voice-callable / impossible" restricts voice-based calls, but data communications Is allowed.

In the example shown in FIG. 20, the destination mobile station 2
008 is the place where voice use is regulated (longitude / latitude)
, The example of transmitting a talkie from the mobile communication exchange 1501 (step 2015) is shown. However, as in the conventional mobile phone service, a message recording service center is connected and a message that the caller wants to convey is displayed. May be adopted.

In the fourth embodiment, an example has been described in which it is determined whether or not transmission and reception by voice are permitted at the start of communication. Next, a case in which a mobile station moves during communication is considered. An embodiment will be described.

[Fifth Embodiment] Next, a fifth embodiment for restricting the use of voice when the mobile station moves from an area where voice communication is permitted to an area where voice communication is not permitted will be described with reference to FIGS. 22 and 23. This will be described using FIG.

FIG. 22 is a table for storing, for each base station, mobile stations that are making a voice call, and as a specific example, a base that stores mobile stations that are making a voice call using base station A. Mobile station registration table 2 during voice call for station A
201 shows a base station B voice communication mobile station registration table 2204 that stores mobile stations that are making a voice call using the base station B.

The tables 2201 and 2042 are
The voice call availability check at the time of outgoing and incoming calls described in the fourth embodiment is OK, and the number of the mobile station used by each mobile station is registered in the table corresponding to the base station when the voice call is established. The registration is canceled when the call is completed. Also, it goes without saying that this information is taken over by the handover destination base station at the time of handover of the base station accompanying the movement of the mobile station. In FIG. 22, the number 2203 of the mobile station A is stored in the voice communication mobile station registration table 2201 for the base station A, and the mobile station B number 2206 is stored in the voice communication mobile station registration table 2204 for the base station B.
Shows an example in which is registered.

FIG. 23 shows mobile station A and mobile station B registered in voice communication mobile station registration table 2201 for base station A and base station B voice communication mobile station registration table 2204 shown in FIG. Is a flowchart showing a process of periodically observing whether or not the mobile terminal has moved to a voice transmission / reception impossible area.

First, when the mobile station A 2301 makes a call (step 2305), a call setup message 2306 is notified to the mobile station control unit 1511 of the mobile communication exchange 1501 via the base station A 2302. In the mobile station control unit 1511, a procedure such as authentication of the mobile station A 2301 according to the related art is performed, and the call setting acceptance message 2307 is transmitted to the mobile station A.
Return to 2301.

Next, the voice transmission / reception identification processing 210 of FIG.
1 (step 2308), and the originating mobile station A2
It is determined whether 301 has made a voice call or a non-voice call (step 2309). If it is determined in step 2309 that a non-voice call has been made, a normal operation is performed (step 2328).

However, if it is determined in step 2309 that a voice call has been made, and if both voice calls and incoming calls are permitted, the mobile station control unit 1511 issues a call to the mobile station B 2304 on the called side according to the prior art. The mobile station control unit 1511 transmits a call setting message 2310 and receives a call setting acceptance message 2311 from the mobile station B.

When mobile station B 2304 responds (step 2312), response message 2313 is sent to mobile station controller 1
511, and the mobile station control unit 1511 notifies the mobile station B 2304 of a response confirmation message 2314.

The mobile station control section 1511 stores the mobile station A 230 in the mobile station registration table 2201 for voice communication for the base station A.
1 is registered (step 2315), and the number 2206 of the mobile station B 2304 is registered in the mobile station registration table 2204 during voice communication for the base station B (step 2316).

Next, step 2317 is a part showing a process of periodically observing whether or not the mobile station A 2301 and the mobile station B 2304 during a voice call have moved to the voice transmission / reception impossible area.

In step 2317, a positioning instruction message is transmitted to mobile station A 2301 registered in mobile station registration table 2201 for voice communication for base station A (step 2318), and voice communication for base station B is further performed. Mobile station B registered in medium mobile station registration table 2204
A positioning instruction message is transmitted to 2304 (step 2321).

On the other hand, mobile station A 2301 extracts longitude and latitude from its own positioning unit 1405 (step 2).
319), the positioning response message is transmitted to the mobile communication switch 150.
1 (step 2320). Similarly, the mobile station B 2304 extracts the longitude and latitude from its own positioning unit 1405 (step 2322), and returns a positioning response message to the mobile communication exchange 1501 (step 23).
23).

Mobile station control unit 1 of mobile communication exchange 1501
At 511, the respective voice transmission / reception disabling display information 1803 is extracted from the current longitude and latitude of the mobile station A 2301 and the mobile station B 2304 (step 2324), and the respective impermissible displays are determined (step 2325).

If it is determined in step 2325 that one of the mobile stations is in the area where voice transmission / reception is not possible, the transmission of a talk indicating that the mobile station has moved to the area where voice communication is not possible is transmitted by voice. An instruction is given to the incoming call non-permitted talkie transmitting unit 1505 (step 2326). As a result, the mobile station A 2301 and the mobile station B 2304 hear the voice call non-permitted talk, and the mobile station A 2301 and the mobile station B 2304 are prompted to disconnect.

As a result, even if one or both of the originating mobile station A 2301 and the destination mobile station B 2304 move to an area where voice transmission / reception is not permitted due to movement during voice communication, voice communication is not performed. It becomes possible to regulate. However, if it is determined in step 2325 that the mobile phone has not moved to the voice call impossible area, step 2317
Continue regular monitoring of

As described above, according to the fifth embodiment, each mobile station is provided with the position detecting means for detecting the current position consisting of the longitude and the latitude. A means of registering voice call disapproval indication information that can specify a specific area that does not allow voice call from longitude and latitude, and a mobile phone call that stores the mobile station number that is making a voice call via its own base station The mobile station stored in the mobile station device registering unit during a voice call is instructed to determine the longitude and latitude at which the mobile station is currently located at predetermined time intervals. Performing the voice transmission / reception disable display information from the longitude and latitude which are the positioning results from the mobile station, and if the mobile station moves to an area where voice transmission / reception is not permitted, voice communication is restricted. That you have moved to the If the mobile station that is talking is moved to an area such as a library where voice communication is not permitted by notifying the mobile station as a key, voice communication is restricted and only data communication is allowed. Becomes possible.

[0151] Even if the disconnection of the telephone call is prompted by the voice call non-permissive talk, the mobile station control unit 1511 may forcibly perform the disconnection process when the voice communication continues for a predetermined time or more. As a result, the effect of restricting the voice call in the non-voice call permitted area is ensured.

[Sixth Embodiment] Next, even in a call in an area where a call by voice is allowed, for example, a voice call in a crowded train has a very low degree of inconvenience to surrounding people. In the case of a large value, a sixth embodiment in which the nuisance call is identified and the disconnection of the voice call is prompted will be described with reference to FIG.

FIG. 24 shows a process of urging the mobile station A to disconnect the voice call in response to a request from the mobile station X when the mobile station A is making a voice call using the base station A. It is a flowchart.

First, when, for example, a special number is dialed from mobile station X 2401 to request rejection of a nuisance call (step 2402), a call setting message is notified from base station A 2402 to mobile station control section 1511 (step 2403). ).

The mobile station control section 1511 notifies the mobile station X 2401 of a call setting acceptance message (step 240).
4). Next, it is determined whether or not the call setting message 2403 is a nuisance call rejection request based on whether or not the dial operation number is a “special number” (step 2405). If the determination result is “YES”, the nuisance call rejection is performed. The mobile station X 2401 that made the request extracts all the mobile stations that are registered in the base station A 2402 used by the base station A 2402 from the voice communication mobile station registration table 2201 for the base station A, and registers the currently registered mobile station. In the case of this example, a positioning instruction message is transmitted to the mobile station A2400 via the base station A2402 (step 2408).

In the mobile station A2400, its own positioning unit 14
05 and the longitude and latitude are extracted (step 2410),
The positioning response message is returned to the mobile communication exchange 1501 (step 2411). Similarly, a positioning instruction message is transmitted to the mobile station X2401 that has issued the unwanted call rejection request via the base station A2402 (step 2409), and the longitude and latitude are extracted from the positioning unit 1405 of the mobile station X2401 ( (Step 2412), and returns the positioning response message to the mobile communication exchange 1501 (Step 2413).

Mobile station control unit 1 of mobile communication exchange 1501
At 511, the positioning response message 2411 and the positioning response message 2 of the mobile station A2400 and the mobile station X2401
Compare the current longitude and latitude notified in 413,
It is determined whether or not the two pieces of positioning information are close to each other with a predetermined accuracy (step 2414). If it is determined that the two pieces of positioning information are close to each other, the voice call is annoying to the surrounding people. The mobile station A240 instructing the voice transmission / reception non-permissible talkie transmitting unit 1505 to send a voice call annoying talk to the effect (step 2415).
A "voice call annoying talk" is sent to 0 (step 2417) to urge disconnection.

If the result of the determination in step 2405 is "NO", a normal connection operation is performed (step 2407). If there is no nearby mobile station in step 2414, the nuisance call rejection process ends (step 2416).

As described above, according to the sixth embodiment, the mobile station is provided with the position detecting means for detecting the current position consisting of the longitude and the latitude, and issues a communication request to each radio base station. Mobile station device registration means for each wireless base station storing the mobile station number and the mobile station number in a communication state, and if a voice call rejection request is transmitted from any of the mobile station devices. A mobile station during voice communication of a number stored in the mobile station apparatus during voice communication corresponding to the wireless base station that has received the voice call rejection request,
The mobile station that has issued the call rejection request is instructed to measure the longitude and latitude at which the mobile station is currently located, and the longitude and latitude, which are the positioning results from the mobile station during a voice call, and the call From the longitude and latitude of the mobile station that issued the rejection request, the mobile station that is in proximity to the mobile station that issued the call rejection request is identified, and the identified mobile station that is engaged in voice communication is identified by voice. By notifying the mobile station apparatus during the voice call that the call is causing annoyance as a talk, a person who is actually receiving the annoyance can take the initiative and regulate the voice call. Also, only data communication can be permitted.

In this case, the mobile station control unit 1551 may forcibly perform the disconnection process if the voice call continues for a predetermined time or longer even if the call is prompted by the voice call non-permissive talk. As a result, the effect of regulating the voice call in the vicinity of the call denial request is assured.

In the example of FIG. 24, the mobile station control unit 15
11 indicates that the location information (longitude / latitude) of the mobile station X2401 is to be collected by the positioning instruction message 2409 from the mobile station X2401 to the mobile station X2401.
Mobile station X in advance in a call setup message 2403 from
The longitude and latitude information measured by the positioning unit 1405 of the 2401 may be set and notified to the mobile communication switching system 1501. By doing so, mobile station X240
1 and the mobile station control unit 1511
Is reduced, and the response performance to the unwanted call rejection request is further improved.

In the example of FIG. 24, base station A 240 used to notify call setting message 2403 of nuisance call rejection request 2402 to mobile communication exchange 1501.
2 is targeted for the positioning instruction request 2408. For example, if one base area covers a plurality of base stations, It is needless to say that the positioning instruction request 2408 is made to all the mobile stations during the voice call of, and the longitude / latitude proximity determination with the mobile station X2401 is performed (step 2414).

Also, in the event of a disaster such as an earthquake, storm or flood, the outgoing / incoming call control described in the fourth, fifth, and sixth embodiments is released by the system operation manager performing a predetermined operation in the PHS exchange. Is done. This allows voice calls during a disaster.

[Seventh Embodiment] FIG. 25 shows that the mobile station itself monitors whether it is in an area where voice communication is not permitted, and that the mobile station itself instructs another mobile station to reject voice communication. FIG. 16 is a block diagram of a digital mobile phone (mobile station) according to a seventh embodiment.

Digital mobile phone 250 of this embodiment.
Reference numeral 1 includes a wireless unit 2502, a control unit 2503, an input / output unit 2504, a voice call rejection signal monitoring unit 2505, a voice call rejection signal transmitting unit 2506, and a voice call rejection talkie output unit 2507.

Radio section 2502 modulates / demodulates and amplifies radio signals, similarly to radio section 1402 of digital portable telephone 1401 in the fourth embodiment. Control unit 25
03 is the same as that used in conventional digital mobile phones.
In addition to call control based on the layer 3 function of SDN, radio management for location registration and connection change between cells, radio management for radio carrier and time slot designation and radio communication quality management, a voice call rejection signal monitoring unit 2505, a voice call rejection signal transmitting unit 2506, and a voice call impossible talkie output unit 2507 are controlled.

The input / output unit 2504 is the input / output unit 1404 of the digital portable telephone 1401 in the fourth embodiment.
In the same manner as in the above, input and output of sound such as a speaker and a microphone and input and output from a device such as a keyboard and a liquid crystal display are performed. The voice call rejection signal monitoring unit 2505 outputs a “voice call rejection signal” having a predetermined frequency, signal pattern, and output level to another mobile station or
Whether or not the signal is transmitted from the dedicated antenna is constantly or periodically monitored. The transmission of the "voice call rejection signal" from the own mobile station is performed by the voice call rejection signal transmission unit 2506.
It is. Also, the voice call disabled talkie output unit 2507 outputs a talk to the mobile station that the voice call is not permitted when the voice call rejection signal is transmitted from another mobile station or a dedicated antenna. It has a function of outputting to a voice or a liquid crystal display or the like.

FIG. 26 is a flowchart showing a process for rejecting a voice call using the digital mobile phone (mobile station) 2501 shown in FIG.

When control unit 2503 of mobile station A receives a voice call rejection request (step 2604), a voice call rejection signal transmission unit 2506 transmits a "voice call rejection signal" (step 2605). As a result, the voice call rejection signal 2606 is transmitted to the mobile station existing in the vicinity of the mobile station A (within the range where the radio wave reaches at the output level of the “voice call rejection signal”), in this example, the mobile station B.

In the mobile station B, the voice call rejection signal monitoring unit 2505 periodically monitors the "voice call rejection signal" (step 2607), and determines the reception status of the "voice call rejection signal" (step 2607). Step 2608). Step 2
If it is determined in 608 that the "voice call rejection signal" has been received, it is determined whether or not the input / output unit 2504 of the mobile station B uses a device such as a microphone and a speaker used for voice calls (step 2609). If it is used, the voice communication disabled talkie output unit 2507 is instructed to send a talkie indicating that voice communication is causing trouble to other people (step 2610), and the voice call disabled talkie is output. Notify the user of mobile station B (step 2611),
A cutting operation 2612 is prompted.

At step 2608, "voice call rejection signal"
Is not received, and if no voice call is made in step 2609, periodic monitoring of the "voice call rejection signal" is performed again.

The output level of the "voice call rejection signal" used in this embodiment is desirably an extremely low level radio wave. If the output level is higher than a certain level, it is more preferable to discard it as a jamming radio wave. This is a desirable determination method.

As described above, according to the seventh embodiment, each mobile station constantly monitors the arrival of a voice call rejection request signal from another mobile station, and the voice call from another mobile station is made. If a rejection request signal is received, it is determined whether or not the own mobile station is in a voice call, and if a voice call is in progress, by notifying the talker that the voice call is not permitted by talk, It is possible to directly restrict a voice call from another mobile station to a mobile station causing trouble to surrounding people. Also, only data communication can be permitted.

Although FIG. 26 shows an example in which a “voice call rejection signal” is transmitted from a mobile station, for example, an antenna for constantly transmitting a “voice call rejection signal” may be installed in a train or in a hotel lobby. It is also possible to restrict the voice communication from the vicinity where the antenna is installed. The antenna in this case corresponds to a transmission operation for transmitting a voice call rejection signal.

[Eighth Embodiment] In the embodiment shown in FIG. 26, a "voice call rejection signal" is also received for a voice call having a very high degree of urgency, such as a voice call between a police agency and a fire department. Then, the voice call will be rejected.
For this reason, as a more preferred embodiment, as shown in the flowchart of FIG.
When 702 is performed, it is determined whether or not the call is an emergency call to an organization such as the police or fire department (step 2703). If the call is an emergency call, monitoring of the voice call rejection signal is stopped (step 2704). It is preferable to use a method of monitoring the voice call rejection signal only when it is determined that the call is a normal call in step 2703 (step 2705).

According to the eighth embodiment, an extremely urgent voice call, such as a voice call with a police agency or a fire department, is permitted regardless of the inconvenience to the surrounding people. Can be reliably ensured.
