Abstract

PURPOSE: To prevent increase in the processing amount by recording a call number and a call time from a caller terminal equipment so as to detect a caller terminal equipment making lots of calls in a short time so as to restrict the call thereby restricting concentrated calls from a mobile terminal equipment. CONSTITUTION: A caller exchange 5 has a function of restricting a call from a caller user terminal equipment 3 based on a command from a gate exchange 7. Furthermore, the gate exchange 7 has a concentrated call detection function that stores and manages the call time and the call number from the caller user terminal equipment 3 via the caller exchange 5 so as to detect the concentrated calls from the caller user terminal equipment 3 thereby and a call restriction function that restricts calls from the caller user terminal equipment 3 based on the result of detection. When the user 1 uses the caller user terminal equipment 3 to make calls, the caller exchange 5 rejects the call when the call of the user 1 is restricted and connects the call to the gate exchange when the user 1 is not restricted. When the call is not restricted, the gate exchange 7 stores the call time and the call number and decides the restriction release time when the user 1 makes calls for a prescribed number of times or over for the preceding prescribed time to start call restriction of the user 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call control method in mobile communication in which a calling terminal, which is a mobile terminal, wirelessly calls a calling switch and calls the called terminal from the calling switch through a gateway switch. More specifically, the present invention relates to a call restriction method in mobile communication that restricts intensive calls from calling terminals.

[0002]

2. Description of the Related Art A communication connection when a calling user and a called user use terminals under different communication networks will be described with reference to FIG. In FIG. 5, the calling user 51 sends a call request from the terminal 53 to the calling switch 57 of the calling network 55.
Then, the line is connected from the originating exchange 57 to the relay exchange 59 and the gateway exchange 61. When connecting the line,
In order to identify the destination user 73, the destination user number is transmitted between the exchanges. From the gateway switch 61 to the incoming network 6
The line is connected to the gateway switch 65 of 3 through POI,
A line is connected from the gateway exchange 65 to the destination user terminal 71 via the relay exchange 67 and the destination exchange 69. At this time, the relay exchange, the gateway exchange, etc. may be different for each call, but P
The position of the OI is specified in order to divide the communication charge between the called user 73 and the calling user 51 by the two communication networks. Further, there may be one gateway exchange connected to the POI for each POI, and in this case, the gateway exchange when the calling user communicates with the called user is always the same.

In a communication network, a user obtains a ticket, redials when the other party is busy, or undesirably, a plurality of message dials for repeatedly calling a plurality of pagers by an automatic calling device to call a plurality of pagers. A call request from a specific user may be intensively made for the purpose of leaving a message, searching for a telephone number that is not being used, decrypting a personal identification number of a telephone service, or the like. In such a case, the amount of processing of the originating exchange and the transit exchange may increase, and it may not be possible for other users to make or receive calls, or the exchange may be stopped, causing other users annoyance. is there. Therefore, it is necessary to regulate such a call request.

As shown in FIG. 6, in the fixed communication network 81, the calling exchange 83 from which the terminal 87 of the user 85 makes a calling request is specified, and the calling exchange 83 detects the above-mentioned intensive calling. It is possible, and in the originating switch 87, for example, 3
Call restrictions such as only accepting calls at 0 second or 1 minute intervals can be performed.

[0005]

As shown in FIG. 7, in the mobile communication network 91, the calling exchange 95 when the user 93 makes a call becomes an exchange near the position where the user is located, When the user makes a call, the originating exchange 95 'may differ for each call. In this case, the above-described increase in processing does not occur or is mitigated in the originating exchange 95. However, the gateway switch 9
7 may be the same and may cause trouble to other users due to an increase in the throughput of the gateway switch, and it is necessary to regulate such a call request.

Further, in mobile communication, the information of the terminal is stored in the home memory 99, and when the user makes a call, the calling exchange 95 reads the information of the terminal from the home memory 99 and performs the calling process. Therefore, if the user makes outgoing calls intensively, the amount of processing in the home memory 99 increases, which causes trouble to other users.

However, since the calling exchange 95 does not generate call requests in a concentrated manner, such a state cannot be detected, and the conventional gateway exchange 97 also obtains the number of the called user in order to connect the line. However, such a condition could not be detected because the calling user number was not obtained.

The present invention has been made in view of the above,
It is an object of the present invention to provide a call origination regulation method in mobile communication in which intensive call origination from a mobile terminal is detected and regulated to prevent an increase in processing amount.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the configuration of a system that implements a call regulation method in mobile communication according to an embodiment of the present invention. In the embodiment shown in the figure, the originating user terminal 3 used by the user 1 is wirelessly connected to the originating exchange 5, and is connected to the other communication network 11 from the originating exchange 5 via the gateway exchange 7 and the POI. It has become. A transit exchange may be connected between the originating exchange 5 and the gateway exchange 7 when making a call.

The originating exchange 5 has a function of restricting a call from the originating user terminal 3 based on an instruction from the gateway exchange 7. Further, the gateway exchange 7 stores and manages the originating time and the originating number from the originating user terminal 3 via the originating exchange 5, thereby detecting the centralized originating call from the originating user terminal 3. It has a function and a call regulation function that regulates the call of the calling user terminal 3 based on the detection result of the centralized call detection function.

Next, with reference to FIG. 2, operations of the originating exchange 5 and the gateway exchange 7 when the originating user terminal 3 makes a call will be described. When the user 1 makes a call from the calling user terminal 3, the calling number and the called number are sent to the calling exchange 5, and the calling exchange 5 checks whether or not the user 1 is under call restriction (step S110). The call is rejected and a reject signal is sent to the calling user terminal 3. If not regulated, the line is connected to the gateway switch 7.

The gateway exchange 7 which has received the line connection checks whether or not the corresponding user is under call control (step S150), and if the user is under control, sends a signal indicating call control to the call exchange 5. This signal includes the time when the regulation is released.

If it is not under regulation, the gateway exchange 7 stores the calling time and calling number (step S160). afterwards,
Examine the record of outgoing calls within a certain period of time, for example, within 3 minutes,
If the user has made a call a certain number of times or more, the restriction release time is determined and the call restriction for the user is started (step S170). Further, a signal indicating that the transmission is restricted is sent to the originating exchange 5. This signal includes the time when the regulation is released. The calling exchange 5 that has received the signal indicating that the call is being restricted restricts the call to the user until the time specified by the signal, and sends a rejection signal to the calling user terminal 3. If the gateway switch 7 does not restrict outgoing calls to the user,
Connect to the incoming network or terminal.

FIG. 3 is a diagram showing the configuration of a system for carrying out a call regulation method according to another embodiment of the present invention. In the embodiment shown in the figure, the originating user terminal 3 used by the user 1 is wirelessly connected to the originating exchange 5, and is connected from the originating exchange 5 to another communication network 11 via the gateway exchange 13 and the POI. It has become. Further, a home memory 15 is connected to the originating exchange 5, and the home memory 15 is shown in FIG.
Instead, it has the centralized call detection function and call restriction function that the gateway switch 7 of FIG. Therefore, the gateway switch 13 does not have a centralized call detection function or a call restriction function. A transit exchange may be connected between the originating exchange 5 and the gateway exchange 13 when making a call. Further, the originating exchange 5 has a function of restricting a call from the originating user terminal 3 based on an instruction from the gateway exchange 13 as in the case of FIG.

Next, the operations of the originating exchange 5 and the home memory 15 when the originating user terminal 3 makes a call will be described with reference to FIG. When the user 1 makes a call from the calling user terminal 3,
The calling number and the called number are sent to the originating exchange 5, and the originating exchange 5 checks whether or not the user is under call control (step S310). If the user is under control, the call is rejected and a call rejection signal is sent to the calling user terminal 3. Is sent. If it is not under regulation, a call information read signal is sent to the home memory 15 to read the call information.

Home memory 1 which has received the outgoing information read signal
5 checks whether or not the corresponding user is under call control (step S250), and if the user is under control, sends a signal indicating call control to the originating exchange 5. This signal includes the time when the regulation is released.

If not restricted, the home memory 15 stores the calling time and calling number (step S360). After that, if the user makes a call for a certain number of times or more within a certain period of time in the past, for example, within 3 minutes, the restriction release time is determined and the transmission restriction for that user is started (step S370). Further, a signal indicating that the transmission is restricted is sent to the originating exchange 5. This signal includes the time when the regulation is released.

The calling exchange 5 which has received the signal indicating that the outgoing call is regulated,
The call is restricted to the user until the time specified by the signal, and a reject signal is sent to the calling user terminal 3. The home memory 15 sends the outgoing call information to the outgoing exchange 5 when the outgoing call is not restricted to the user. After receiving the outgoing call information, the originating exchange 5 performs a normal outgoing call operation.

[0025]

As described above, according to the present invention,
It records the calling number and calling time from the calling terminal, detects the calling terminal that made many calls in a short time, sends an instruction to restrict calling from the calling terminal to the calling switch, and Since outgoing calls are regulated by the originating exchange, it is possible to prevent an increase in the throughput of the exchange and prevent congestion or failure of the communication network.

Further, according to the present invention, the gateway exchange or the home memory records the calling number and the calling time of the calling terminal, detects the calling terminal which has made many calls in a short time, and detects the calling from the calling terminal. Since an instruction to control the signal is sent to the originating exchange and the call from the calling terminal is regulated at the originating exchange, it is possible to prevent an increase in the throughput of the exchange and the home memory, and to prevent congestion or failure of the communication network. Can be prevented.
