Referring to FIG. 4, according to the conventional call regulation system, a broadcast channel (BCCH) is transmitted from a mobile telephone service network.
When the regulation notification information is transmitted by (step S40)
1) The mobile telephone terminal receives the regulation notification information (S402). Then, the individual number (M
The group is calculated by (SI) (S403), and the group of mobile telephone terminals to which the outgoing call is to be restricted is determined from the restriction notification information received in S402 and the group number calculated in S403 (S404). ), The grouping regulation is executed (S405).

As an example of a conventional transmission control system of this kind,
The "transmission control method" disclosed in Japanese Patent Laid-Open No. 5-336038 and the "regulation method for each radio base station" described in Japanese Patent Application Laid-Open No. 4-35023 can be mentioned.

In all of these regulation systems, the transmission regulation information is transmitted to the cell site or the radio base station where the exchange is congested.

[0006]

In the conventional system for restricting outgoing call based on the restriction notification information by the BCCH from the mobile telephone service network, a plurality of mobiles having the same group number in the same mobile telephone service network. If there is a telephone terminal, the mobile telephone terminals that are subject to call control are always biased toward a specific group of terminals, and it is not possible to perform ideal call regulation where all mobile telephone terminals should be controlled to call equally. was there. And this problem became more serious when the traffic was high.

The present invention has been made in view of the situation in which there is a concern that a shortage of wireless lines will occur due to the rapid increase in the number of mobile phones in use today. As a result, effective use of resources can be achieved, and by using random number generation means, the traffic volume can be controlled regardless of the digital mobile telephone terminal model, individual number, etc., and ideal transmission control can be performed. The purpose is to provide a transmission restriction method.

[0008]

According to the present invention, there is provided a call regulation system characterized in that the digital mobile telephone terminal itself has a self-call regulation means for regulating a call to the mobile telephone service network.

Further, the digital mobile telephone terminal is provided with a judging means for judging the level of traffic based on the random number from the random number generating means and the regulation notification information received from the mobile telephone service network through the notification channel. When the means determines that it is necessary to restrict transmission, the number of times of random number generation from the random number generation means is determined according to the degree of the restriction on transmission, thereby providing a transmission restriction system.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a digital mobile telephone terminal showing an embodiment of a call restriction system of the present invention.

Referring to FIG. 1, a digital mobile telephone terminal 1 of this embodiment has a radio unit 2 for directly exchanging data with a mobile telephone service network (not shown) through an antenna, a power source control unit, A logic unit 3 that performs control including voice input / output control and CPU control; and a communication protocol control unit 4 that determines whether or not communication according to the RCR standard RCR-STD27 is being performed and performs necessary control. It is composed of an operation unit 5 having a calling / receiving function and a display function.

The radio unit 2 cooperates with the logic unit 3 to also perform carrier modulation / demodulation on data conforming to the communication protocol. The functions of the communication protocol control unit 4 and the operation unit 5 are generally realized by software.

Next, the operation of the communication protocol control unit 4 will be described with reference to FIGS.

FIG. 2A is a block diagram of an example of the communication protocol control unit in FIG. 1, and FIG. 2B is a flow chart showing the processing procedure of FIG.

The data receiving unit 41 receives a control signal from the mobile telephone service network through the wireless unit 2 (step S20).
1) Extract each layer 3 information of the radio device management information (RT), the mobile device management information (MM) and the call control information (CC) from the layer 2 information of this reception control signal (S202) and the data analysis unit 42. Hand over to.

The data analysis unit 42 analyzes each information (RT, MM, CC) of the layer 3 information from the data reception unit 41 (S203), and if the analysis result is valid data (S2).
This is notified to the communication protocol determination unit 43. If NO in S204, that is, if the data is invalid data (for example, data that is not addressed to the terminal itself), it is discarded (S2).
08).

The communication protocol determination unit 43 determines the communication protocol for executing control according to a predetermined communication protocol (eg, RCR-STD27) (S205).

Thereafter, the data creation unit 44 creates layer 3 information according to the communication protocol determined by the communication protocol determination unit 43 (S206) and sends it to the data transmission unit 45 as upstream transmission data.

Then, the data transmission unit 43 performs joint ride control for adding the layer 2 information to the layer 3 information created by the data creation unit 42 and sends the data to the radio unit 2 (S).
207).

Next, FIG. 3 is a state transition diagram showing the state transition when the communication protocol determination unit in FIG. 2 executes control.

Referring to FIG. 3, first, a so-called "perch" channel is scanned to find a place where the radio wave is strong.
If there is an effective channel with strong radio waves, that channel is selected as the standby channel, and the standby state becomes possible and the standby state is entered.

When a signal is received from the mobile telephone service network, the traffic amount is determined by the traffic determination processing from the reception control channel structure information in the BCCH and notified. In this traffic determination, it is determined that the traffic is high when the grouping number Np of mobile telephone terminals in the reception control channel structure information is large.

On the basis of the traffic judgment result, if the traffic is high at the time of the transmission request, a random number generator (not shown) generates a random number, and the generated random number and a preset numerical value group are used. Compare. Then, only when the two numerical values match, the call is made possible and the communication is performed, and the call returns to the standby state by the termination of the call.

If the traffic is low at the time of the call request, the communication is performed as it is.

Regarding the above-mentioned preset numerical value group, numerical values inversely proportional to the traffic volume are set.
That is, the larger the traffic volume, the smaller the number of numerical values that can be transmitted.

Further, in order to reduce the apparent inability to make a call, when the call becomes impossible once, the process returns to the standby channel selection processing to set a standby state in another channel.

[0028]

As described above, according to the present invention, the digital mobile telephone terminal itself is provided with the self-transmission regulating means for regulating the transmission to the mobile telephone service network, and in an embodiment, the digital mobile telephone terminal. Has a determination means for determining the level of traffic based on the random number from the random number generation means and the restriction notification information received from the mobile telephone service network through the notification channel, and it is determined that this determination means needs to restrict transmission. At the same time, by determining the number of times of random number generation from the random number generation means according to the degree of transmission restriction, all digital mobile telephone terminals regulate transmission at the same rate according to the traffic volume of the mobile telephone service network. Therefore, it is possible to equalize the line usage rates.
