Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile terminal, and more particularly, to a process of a mobile terminal that is subject to access restrictions.

[0002]

2. Description of the Related Art In recent years, there has been remarkable progress in mobile communication systems such as portable telephones and PHSs. In this mobile communication system, a mobile communication terminal communicates with a network, a base station, a master unit, or the like (hereinafter, referred to as “CS”). However, there is a limit to the line processing of the CS, and if it exceeds this, access control may be performed on the mobile terminal. This access restriction includes “transmission restriction” for restricting transmission and “location registration restriction” for restricting location registration. Here, the "outgoing call restriction" is to restrict outgoing calls from the mobile terminal. In this outgoing call restricted state, incoming calls can be made. On the other hand, the "position registration restriction" restricts position registration of the mobile terminal. In this position registration restriction state, an incoming call cannot be made but a call can be made. These access restrictions are performed in order to reduce the total amount of outgoing calls when outgoing calls are concentrated and all communication services cannot be handled in a disaster or the like.

[0003] The operation in the transmission restriction will be briefly described. The basic operation of the transmission restriction is based on the standard STD.
-28 "2nd generation digital cordless telephone system". First, mobile terminals are classified into a plurality of restriction groups. For example, in the public of PHS, it is classified into eight regulation groups (incoming call groups). Then, based on the information on the number of incoming call groups given in advance, each mobile terminal belongs to itself based on its own mobile terminal number (usually at least a part of its own telephone number is used) and the number of restricted groups. Calculate the control group. For example, incoming call group = (mobile terminal number /
(The number of incoming groups) +1. The number of incoming call groups indicates how many control groups are classified.

[0004] The restriction information is notified to the mobile terminal as one information element of the system information notification message notified from the network side. This regulation information includes regulation group designation information indicating which regulation group was regulated. Each mobile terminal determines whether or not the restriction group to which the mobile terminal belongs and the restriction group indicated by the restriction group designation information match, and if they match, controls the outgoing call and controls so that the calling operation cannot be performed. .

[0005] The regulation information includes information on the number of regulation groups and regulation group designation information indicating which regulation group was regulated, and includes information on the number of regulation groups included in the regulation information. May be calculated. As described above, when the number of control groups is eight, the control levels can be set to eight levels at intervals of 12.5% from 0% to 100%. In addition, in order to equally control each mobile terminal, the restriction group designation information changes with time, and the release of restriction on one restriction group and new restriction on another restriction group are repeated.

[0006] Also in the location registration, the same operation as the above-mentioned transmission restriction is performed, and each mobile terminal calculates a restriction group to which the mobile terminal belongs, and the calculated restriction group matches the restriction group indicated by the restriction group designation information. It is determined whether or not the location registration is performed, and if they match, the location registration is restricted, and control is performed so that the location registration operation cannot be performed.

[0007]

However, in the above-mentioned conventional mobile communication system, when the restriction information is received, only the predetermined restriction is performed, and the user is not notified that the restriction is performed. Therefore, the user cannot make a call despite performing a call operation, and if a call does not arrive at all, the user may not be able to understand why such a phenomenon occurs and confusion may occur. There is a possibility that the terminal manufacturer, or even the communication carrier, may be distrusted. In other words, in the conventional mobile terminal, if the electric field strength of the received radio wave is within the range in which the receiving operation can be performed, the electric field strength level is displayed as a bar graph even if the reception is restricted, indicating that the mobile phone is within the communication area. From this display, the user thinks that he can make and receive calls. Therefore, the present invention provides a mobile terminal capable of notifying a user that the mobile terminal is being restricted when restrictions such as transmission restriction and location registration restriction are performed, and the mobile terminal is restricted. The purpose is to do.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a first object of the present invention is to provide a mobile terminal for performing wireless communication with another communication device, When the restriction information for the mobile terminal is transmitted from another communication device, a notification unit for notifying an operator of the content of the restriction information is provided. In the mobile terminal having the first configuration, when the restriction information for the mobile terminal is transmitted from the other communication device, the notifying unit:
The operator is notified of the content of the regulation information. Therefore, the operator can know the contents of the regulation on the mobile terminal.

[0009] Secondly, in the above-mentioned first configuration, the restriction information is information relating to a transmission restriction in which a call operation cannot be performed from the mobile terminal. Thirdly, in the first or second configuration, the regulation information is information relating to location registration regulation in which the mobile terminal cannot perform location registration.

Fourthly, in any one of the first to third configurations, the notifying means has a display means, and the notifying means displays the contents of the regulation information on the display means. It is characterized by. Therefore, the operator can know the contents of the regulation by visually checking the display on the display means. Fifth, in any one of the first to fourth configurations, the notifying unit includes an output unit that outputs a sound or a voice. Therefore, the contents of the regulation can be known by sound or voice. Sixth, in any of the first to fifth configurations,

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a mobile station A as a mobile terminal according to the present invention includes an antenna unit 10, an RF unit 12, a modem unit 14, a TDMA
A processing unit 16, an ADPCM unit 18, a microphone unit 20,
Speaker section 22, synthesizer section 24, display section 26
, A key input unit 28, a storage unit 30, and a control unit 32.

Here, the RF unit 12 includes the antenna unit 1
It performs wireless processing such as frequency conversion of a received signal received via the “0”, and specifically includes a transmission amplifier, a reception amplifier, and a transmission / reception circuit. The transmission frequency and the reception frequency of the transmission / reception circuit are determined by the oscillation frequency of the synthesizer unit 24. In addition, the modem unit 14
Performs modulation / demodulation processing of transmission / reception signals, and the TDMA processing unit 16 performs transmission path access control according to the TDMA / TDD system. In addition, the above ADP
The CM unit 18 compresses and expands the audio signal according to the ADPCM. The display unit 26 displays various information, and is constituted by an LCD or the like. The key input section 28 is for performing various operations, and is composed of dial keys and the like. Further, the storage unit 30 includes:
It is composed of RAM, ROM, etc., stores various information,
In particular, it stores the program shown in the flowchart of FIG. 2 and also stores regulated output information for displaying on the display unit 26 or outputting it by voice. This restriction output information is information relating to access restriction of the own mobile device, and includes, for example, “under restriction”, “under transmission restriction”, “under location registration restriction”, “restriction release”, “release of transmission restriction”, “ Information such as "location registration release". The control unit 32 controls the operation of each unit in the mobile device A. In particular, the control unit 32 controls the operation of each unit according to the flowchart shown in FIG. That is, the display unit 26, the speaker unit 22, the storage unit 30, and the control unit 32 function as the notification unit. In particular, the display unit 26 functions as the display unit, and the speaker unit 22 functions as the output unit.

Next, the operation of the mobile unit A having the above configuration will be described with reference to FIG. First, the CS of the base station etc.
The signal transmitted to each mobile station has a superframe configuration as shown in FIG. here,
The superframe consists of one superframe from the BCCH to the position before the next BCCH (strictly, the BCCH is BCCH (A)). In this superframe, a PCH corresponding to each paging group is included. Each mobile station controls the reception timing so as to receive the PCH corresponding to the paging group to which it belongs. This P
A state number is assigned to the CH, and when there are changes in various items such as access control being performed on the corresponding incoming call group or access control being released, this state number is updated and changed together with the updated state number. Item is shown. For example,
When the access restriction is changed, that is, when a certain paging group is subject to access restriction or when the access restriction of a certain paging group is released, the information of the access restriction is stored in the system information notification message. So
Information "system information broadcast message" is indicated on the PCH together with the updated state number.

Therefore, first, the mobile station A receives the PCH of the destination group to which the mobile station A belongs in the same manner as in the conventional case, and determines whether the state number has been changed (S10). Here, the incoming call group to which oneself belongs belongs is calculated from the own mobile terminal number (usually at least a part of one's own telephone number is used) and a predetermined number of incoming call groups to which oneself belongs. .

If there is a change in the state number,
The changed item is confirmed (S11). Then, when there is a change in the access restriction, the PCH shows the information “system information broadcast message” together with the updated state number, for example, as described above. It is confirmed that there was. Therefore, the reception timing is controlled so as to receive the data of the change item (S12). That is, when the “system information notification message” is changed, the reception timing is controlled so as to receive the system information notification message.

Then, it is determined from the system information notification message whether or not the mobile station A is restricted (S).
13). In this system information notification message, regulation information is stored, and in this regulation information, regulation group designation information indicating whether or not a predetermined reception group is regulated as a regulation group in outgoing call regulation and location registration regulation is stored. Therefore, by analyzing the restriction group designation information, it is possible to identify the reception group (restriction group) that is restricted in outgoing call or location registration. For example, as shown in FIG. 4, in the restriction group designation information in the system information notification message, it is possible to know which paging group is restricted by setting the bit corresponding to each paging group to 0 or 1. . The restriction group designation information shown in FIG. 4 is provided for transmission restriction and position registration restriction based on the wireless channel use restriction information in the system information broadcast message. If the mobile station A belongs to the paging group 3, the second bit data in the transmission restriction data in the system information broadcast message is 0.
It is determined whether or not the own mobile device A is outgoing call restricted. Also, regarding the position registration restriction, it is determined whether the second bit data in the data of the position registration restriction in the system information notification message is 0 or 1, and it is determined whether the transmission of the own mobile station A is restricted. .

If the mobile unit A is regulated, the control unit outputs restriction output information indicating that the restriction is imposed, and notifies the user that the restriction is imposed. That is, the control unit 32
Outputs the regulated output information stored in the storage unit 30. For example, the fact that it is regulated is displayed on the display unit 26 and notified. As the display content, for example, "under regulation"
And so on. In addition, "outgoing call restriction" may be displayed in the case of outgoing call regulation so that the content of the regulation can be identified, and "position registration in progress" may be displayed in the case of position registration control. In addition, the contents of the display are displayed on the speaker unit 2.
2 may be output as voice. For example, when a call operation is performed, a voice message “Regulating” is provided. It should be noted that, when the operation is restricted, the operation is controlled in accordance with the contents of the restriction. That is, in the case of transmission restriction, the operation is controlled so that the transmission operation cannot be performed, and in the case of position registration restriction, the operation is controlled so that position registration cannot be performed. Specifically, such a transmitting operation is not performed when a signal for position registration is originally transmitted from the mobile device side by moving in the area of the base station.

On the other hand, if the own mobile station A is not subject to the restriction, it means that the state number has been changed and is not subject to the restriction. It outputs the regulation output information indicating that the regulation has been released, and notifies that the regulation has been released. For example, the fact that the regulation has been released is displayed and notified on the display unit 26. The display content is displayed, for example, as “restriction release”. Also,
In order to identify the content of the restriction release, "Call restriction release" may be displayed in the case of call restriction release, and "Location registration restriction release" may be displayed in the case of position registration restriction.
Further, the content of the display may be output from the speaker unit 22 by voice. For example, when the release is detected, a notification that "the restriction has been released" is given by voice. When the regulation is released, the operation is controlled to release the restricted operation. Note that sound may be output from the speaker unit 22 instead of sound. For example, a predetermined sound is made to correspond to “outgoing call regulation”, and another sound is made to correspond to “location registration regulation” to output a sound.

In the above description, the access control is performed by using the predetermined incoming call group also for the control group. However, the control information in the system information notification message includes the control group designation information and the control group designation information. The information on the number of control groups is stored, and the control group to which the own mobile device belongs is calculated from the information on the number of control groups. Based on the belonging control group and the control group designation information, the own mobile device is subject to the control. It may be determined whether or not there is any.

In addition, a group of incoming calls to be regulated (regulation group)
May be plural at the same time. For example, if the call is classified into eight call groups as a whole, the call group 1 and the call group 2 may be restricted at the same time. In addition, as in the conventional case, in order to regulate each mobile device equally, the restriction group designation information changes with time, and the release of the restriction for one restriction group and the new restriction for another restriction group are repeated. .

[0021] When a system information notification message is received, it is possible to know which incoming call group is regulated.
The regulated ratio may be displayed simultaneously. For example, when four outgoing call groups out of the eight incoming call groups are regulated, "50% regulated" is displayed.

[0022]

According to the mobile terminal according to the present invention, when the mobile terminal is subject to regulation or when the regulation is released, the operator can know that fact.
