Abstract

<P>PROBLEM TO BE SOLVED: To prevent wasteful transmission and reception when a mobile communication terminal frequently moves out of service area, or when the control signal from a base station is frequently interrupted even in a service area. <P>SOLUTION: When a reception level unit time average A stored in a reception level unit time average storage 305 falls to or below a call termination rejection threshold value B which is stored in a call termination rejection threshold value storage 312, no-service condition is displayed on a display unit 5 and call termination rejection is transmitted to a radio base station. A transfer process or answerphone process is performed on the radio base station side. The call termination rejection is stored in a call termination rejection part 311, and a reception terminal side rejects call termination as well. If the reception level unit time average A exceeds the call termination rejection threshold value B, a call origination/call termination part 309 prepares for starting of a call. Call origination is allowed when the reception level unit time average A exceeds the call termination rejection threshold value B, but the call origination is prohibited if the reception level unit time average A falls to or below the call termination rejection threshold value B, thus preventing wasteful call origination which is possible to be interrupted. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、移動通信端末、基地局及び移動通信端末制御方法に関し、特に、移動通信端末の移動に伴って基地局を切替える際に、移動通信端末の電池エネルギーが消耗することを防止する移動通信端末、基地局及び移動通信端末制御方法に関する。   The present invention relates to a mobile communication terminal, a base station, and a mobile communication terminal control method, and more particularly, mobile communication that prevents battery energy of a mobile communication terminal from being consumed when the base station is switched as the mobile communication terminal moves. The present invention relates to a terminal, a base station, and a mobile communication terminal control method.

移動中の移動通信端末が着信待受状態にあるとき、通話やデータ送信は行われていないため、電池エネルギーを節約することが好ましい。   When the moving mobile communication terminal is in an incoming call waiting state, it is preferable to save battery energy because no telephone call or data transmission is performed.

ところで、一般的には、着信待受状態では、基地局からの呼出しを移動通信端末側で受信するために、基地局の無線チャンネル中の制御信号を受信している。   By the way, in general, in the incoming call waiting state, a control signal in the radio channel of the base station is received in order to receive a call from the base station on the mobile communication terminal side.

そこで、着信待受状態での電池エネルギー節約のため、特許文献１においては、基地局のサービス圏外の場合（基地局からの制御信号が受信できなかったとき）や、移動通信端末が高速移動中である場合（移動通信端末が受信する制御信号の受信回数が基準値未満のとき）に、制御信号の周期より大幅に長い時間を停止時間としてタイマを起動し、電源回路をオンからオフに切替える。   Therefore, in order to save battery energy in the waiting state for incoming calls, in Patent Document 1, when the mobile station is outside the service area of the base station (when the control signal from the base station cannot be received) or the mobile communication terminal is moving at high speed When the control signal is received (the number of times the control signal received by the mobile communication terminal is less than the reference value), the timer is started with the time significantly longer than the control signal cycle as the stop time, and the power supply circuit is switched from on to off. .

特許文献２においては、移動通信端末が連続して基地局のサービスエリア圏外にあるときは、通常の受信部の動作を停止させ、通常の受信回路より低電力の受信回路により全受信帯域内の電波の有無を検出する。   In Patent Document 2, when the mobile communication terminal is continuously outside the service area area of the base station, the operation of the normal reception unit is stopped, and the reception circuit having a lower power than the normal reception circuit is used. Detect the presence of radio waves.

特許文献３では、病院、映画館、コンサートホールなどにおける着信を防止するため、ユーザが一時着信拒否モードを設定することにより、着信音が鳴らず留守番電話状態とするため、電池エネルギーを節約する効果が得られる。その後その場所を離れて別の基地局のサービス圏内に入ったときに、一時着信拒否モードが自動的に解除される。   In Patent Document 3, in order to prevent incoming calls in hospitals, movie theaters, concert halls, etc., the user can set a temporary incoming call rejection mode so that a ringing tone does not sound and an answering machine is set. Is obtained. Thereafter, when the user leaves the place and enters the service area of another base station, the temporary incoming call rejection mode is automatically canceled.

特開平７−８７０１０号公報（段落番号〔００３０〕〜〔００３１〕、図１）Japanese Patent Laid-Open No. 7-87010 (paragraph numbers [0030] to [0031], FIG. 1) 特開平１１−３３１０２３号公報（段落番号〔００２５〕〜〔００３０１〕、図２）Japanese Patent Laid-Open No. 11-331023 (paragraph numbers [0025] to [00301], FIG. 2) 特開２００４−１５４２０号公報（段落番号〔００１６〕〜〔００２２〕、図２）JP 2004-15420 A (paragraph numbers [0016] to [0022], FIG. 2)

しかし、基地局のサービスエリアは、利用者密度に応じて、セル半径０．５〜３ｋｍと多様化している。そのため、特許文献１のように、電源回路を一律に長い停止時間の間オフしたのでは、停止時間が長くなりすぎ着信の機会を見過ごす虞がある。   However, the service area of the base station is diversified with a cell radius of 0.5 to 3 km according to the user density. Therefore, as in Patent Document 1, if the power supply circuit is turned off for a long stop time uniformly, the stop time becomes too long, and there is a possibility of overlooking the incoming call opportunity.

また、セルが小さくなるほど、地形、道路、建造物の影響により、同じ基地局のサービスエリアでありながら短時間で頻繁に通信信号が途絶することがある。したがって、特許文献２のように、一定周期で基地局から送信されてくる制御信号を連続して受信しているか否かの判定が難しくなる。   Further, as the cell becomes smaller, the communication signal may be frequently interrupted in a short time despite the service area of the same base station due to the influence of topography, roads, and buildings. Therefore, as in Patent Document 2, it is difficult to determine whether or not the control signal transmitted from the base station is continuously received at a constant period.

更に、特許文献３では、基地局のサービスエリアが広いときは、歩行中のユーザなどにとって一時着信拒否モードがすぐには解除されず、ユーザに不便である。また、移動通信端末が頻繁に圏外に移動する場合や、小さなセル内で、地形、道路、建造物の影響により、頻繁に通信信号が途絶する場合に、電池エネルギーを節約するという目的を達成することはできない。   Further, in Patent Document 3, when the service area of the base station is large, the temporary incoming call rejection mode is not canceled immediately for a user who is walking or the like, which is inconvenient for the user. It also achieves the goal of conserving battery energy when mobile communication terminals frequently move out of range or when communication signals are frequently interrupted in small cells due to terrain, roads, and buildings. It is not possible.

移動通信端末が頻繁に圏外に移動する場合に、又は、１つのサービス圏内であっても基地局からの制御信号が頻繁に途絶する場合に、通話やデータ送受信を行っても、無駄になる虞がある。   If mobile communication terminals frequently move out of service area, or if control signals from the base station are frequently interrupted even in one service area, there is a risk that it will be wasted even if a call or data transmission / reception is performed. There is.

そこで、本発明は、移動通信端末が頻繁に圏外に移動する場合に、又は、１つのサービス圏内であっても基地局からの制御信号が頻繁に途絶する場合に、無駄な送受信を防止して送受信に係る電力を節約することを目的とする。   Therefore, the present invention prevents useless transmission / reception when a mobile communication terminal frequently moves out of service area or when a control signal from a base station is frequently interrupted even in one service area. The purpose is to save power related to transmission and reception.

以下、図面を参照して、本発明の実施例について説明する。   Embodiments of the present invention will be described below with reference to the drawings.

The mobile communication terminal according to the present embodiment includes a keyboard unit (input device) 4, a program unit 3 that inputs / outputs, calculates, and stores information according to a program, and a display unit 5 that displays information, and wireless communication. Unit 1, audio unit 2 that handles voice of a call, microphone 7 that outputs an audio signal to audio unit 2, speaker 8 that receives a received audio signal from audio unit 2, and antenna that transmits and receives radio waves for communication 6 are included.

プログラム部３は、操作判定部３０１、受信レベル検出部３０２、基地局検出部３０３、単位時間設定部３０４、受信レベル単位時間平均記憶部３０５、基地局記憶部３０６、キー操作認識・表示部３０７、待受部３０８、発信・着信部３０９、圏外表示部３１０、着信拒否部３１１、着信拒否閾値記憶部３１２を含む。   The program unit 3 includes an operation determination unit 301, a reception level detection unit 302, a base station detection unit 303, a unit time setting unit 304, a reception level unit time average storage unit 305, a base station storage unit 306, a key operation recognition / display unit 307. A standby unit 308, a transmission / reception unit 309, an out-of-service display unit 310, an incoming call rejection unit 311, and an incoming call rejection threshold storage unit 312.

なお、プログラム部３の各部３０１から３１２の機能は、図２のフローチャートの説明中において行う。   The functions of the units 301 to 312 of the program unit 3 are performed during the description of the flowchart of FIG.

キーボード部４は、テンキー、コマンドキー（発（発信）、再（再発信）、終（終話）、Ｆ（小文字）、Ｍ〔メモリ〕、ＣＬ（クリア）、Ｍｎ（マナー）、Ｃａ（コール）、Ｐｏ（電源））を含む。キーボード部４の出力はキー操作認識・表示部３０７へ入力され、表示が必要な情報はキー操作認識・表示部３０７から表示部５へ出力される。   The keyboard unit 4 has ten keys, command keys (calling (calling), replaying (recalling), ending (ending call), F (lowercase), M (memory), CL (clear), Mn (manner), Ca (call) ), Po (power supply)).

以上、図1を参照して移動通信端末の公正について説明したが、これに限らず、デジタルカメラやＧＰＳ装置を無線部１に接続してもよい。   The fairness of the mobile communication terminal has been described above with reference to FIG. 1, but the present invention is not limited to this, and a digital camera or a GPS device may be connected to the wireless unit 1.

[移動通信端末の動作]
回線接続された基地局Ｘからの受信レベルの単位時間平均Ａが所定の値（着信拒否閾値Ｂ）以下となった場合、表示部５に圏外動作であることを表示するとともに、着信拒否を着信拒否部３１１に記憶し、着信を拒否する。着信拒否を無線基地局Ｘに送信することにより、無線基地局側では転送処理又は留守番電話処理を行う。したがって、着信拒否が基地局Ｘに到達しなくても、移動通信端末では、着信に係る電池エネルギーの消耗はない。 [Mobile communication terminal operation]
When the unit time average A of the reception level from the base station X connected to the line is equal to or less than a predetermined value (incoming call rejection threshold B), the display unit 5 displays that the operation is out of service area and receives an incoming call rejection. Store in the rejection unit 311 and reject the incoming call. By transmitting the incoming call rejection to the radio base station X, the radio base station performs transfer processing or answering machine processing. Therefore, even if the incoming call rejection does not reach the base station X, the mobile communication terminal does not consume battery energy associated with the incoming call.

一方、受信レベル単位時間平均Ａが着信拒否閾値Ｂを超える場合は、発信・着信部３０９にて通話開始に備える。   On the other hand, when the reception level unit time average A exceeds the incoming call rejection threshold B, the transmission / reception unit 309 prepares for the start of a call.

発信動作については、受信レベル単位時間平均Ａが着信拒否閾値Ｂを超える場合は発信・着信部３０９にて発信は可能とされるが、受信レベル単位時間平均Ａが着信拒否閾値Ｂ以下となった場合は発信・着信部３０９にて発信は禁止される。これによって、有効な発信（途中で途切れる可能性が低い発信）を行い、無駄な発信（途中で途切れる可能性が高い発信）を防止する。   As for the transmission operation, when the reception level unit time average A exceeds the incoming call rejection threshold B, the transmission / reception unit 309 can make a call, but the reception level unit time average A is equal to or lower than the incoming call rejection threshold B. In this case, the transmission / reception unit 309 prohibits the transmission. Thus, effective transmission (transmission with low possibility of being interrupted in the middle) is performed, and useless transmission (transmission with high possibility of being interrupted in the middle) is prevented.

具体的には、上記移動通信端末の電源をオンし、移動通信端末周辺の複数の基地局からの制御信号を待受け、その中から回線接続された基地局Ｘを、記基地局記憶部３０６に記憶する。   Specifically, the mobile communication terminal is turned on, receives control signals from a plurality of base stations around the mobile communication terminal, and the base station X connected to the line from the base station X is stored in the base station storage unit 306. Remember.

ここで、移動通信端末がＧＰＳを内蔵する場合又はそれに接続されている場合、上記着信拒否閾値Ｂと上記受信レベル単位時間平均Ａとを比較し、上記Ａが上記Ｂを超えるときは上記移動通信端末の位置情報（ＧＰＳによる）を上記基地局Ｘを介して通信の相手方に送信した後に、上記Ｂを、着信拒否閾値記憶部３１２に記憶する。一方、上記Ａが上記Ｂを超えないときは上記移動通信端末の位置情報（ＧＰＳによる）を上記基地局Ｘへ送信することなく、上記Ｂを、着信拒否閾値記憶部３１２に記憶する。   Here, when the mobile communication terminal incorporates or is connected to the GPS, the incoming call rejection threshold B is compared with the reception level unit time average A, and when the A exceeds B, the mobile communication terminal After the terminal location information (by GPS) is transmitted to the other party of communication via the base station X, the B is stored in the incoming call rejection threshold storage unit 312. On the other hand, when the A does not exceed the B, the B is stored in the incoming call rejection threshold storage unit 312 without transmitting the position information (by GPS) of the mobile communication terminal to the base station X.

上記Ｂを、着信拒否閾値記憶部３１２に記憶した後、上記着信拒否閾値Ｂと上記受信レベル単位時間平均Ａとをさらに比較する。そして、比較の結果、上記Ａが上記Ｂを超えないときは着信拒否を着信拒否部３１１に記憶し、基地局Ｘにも着信拒否を送信する。一方、上記Ａが上記Ｂを超えるときは以前に着信拒否部３１１に記憶した着信拒否を解除する。この着信拒否解除は基地局Ｘに送信する。   After B is stored in the incoming call rejection threshold storage unit 312, the incoming call rejection threshold B and the reception level unit time average A are further compared. As a result of comparison, when A does not exceed B, the incoming call rejection is stored in the incoming call rejection unit 311 and the incoming call rejection is also transmitted to the base station X. On the other hand, when A exceeds B, the incoming call rejection previously stored in the incoming call rejection unit 311 is canceled. This incoming call rejection cancellation is transmitted to the base station X.

上記着信拒否が着信拒否部３１１に記憶されたときは、再度、待受動作に戻る。
一方、上記着信拒否が解除されたときは、通話、終話を行う処理を行う。 When the incoming call rejection is stored in the incoming call rejection unit 311, the process returns to the standby operation again.
On the other hand, when the incoming call rejection is cancelled, a process for making a call and ending the call is performed.

[移動通信端末制御方法]
図２は、移動通信端末の制御方法のフローチャートである。
まず、ステップＳ１０において、ユーザにより電源がオンとされる。
次にステップＳ２０において、操作判定が行われる。この操作判定において、電源オン直後は常に待受動作ＳＴＡＲＴが選択される。なお、ステップＳ１２０、Ｓ１３０、Ｓ２３０、Ｓ２４０から、ステップＳ３０に戻ってきた場合、着信拒否が記憶されている場合は、待受動作ＳＴＡＲＴ（ステップＳ２０）が選択される一方、着信拒否が解除されている場合は、発信・着信ＳＴＡＲＴ（ステップＳ２００）が選択される。 [Mobile communication terminal control method]
FIG. 2 is a flowchart of a method for controlling the mobile communication terminal.
First, in step S10, the power is turned on by the user.
Next, in step S20, operation determination is performed. In this operation determination, the standby operation START is always selected immediately after the power is turned on. When returning to step S30 from steps S120, S130, S230, and S240, if incoming call rejection is stored, standby operation START (step S20) is selected, while incoming call rejection is canceled. If there is, the outgoing / incoming START (step S200) is selected.

次に、ステップＳ３０において、待受動作が待受部３０８にて開始される。
具体的には、ステップＳ４０において、回線接続した基地局Ｘが基地局記憶部３０６に記憶される。より具体的には、まず、移動通信端末の周辺の１以上の基地局からの電波を受信し、受信レベルが受信レベル検出部３０２により検出される。続いて、受信レベルを比較し、最も受信レベルが高い基地局を回線接続すべき基地局Ｘとする。なお、ステップＳ１２０、Ｓ１３０、Ｓ２３０、Ｓ２４０から、ステップＳ３０に戻ってきた場合、すでに記憶している基地局Ｘと、最も受信レベルが高い基地局とを比較し、同一基地局である場合は基地局記憶部３０６の記憶内容は変化はないが、異なるときは、最も受信レベルが高い基地局と新たに認定された基地局が、基地局Ｘとして更新される。 Next, in step S <b> 30, a standby operation is started in the standby unit 308.
Specifically, in step S40, the base station X connected to the line is stored in the base station storage unit 306. More specifically, first, radio waves from one or more base stations around the mobile communication terminal are received, and the reception level is detected by the reception level detection unit 302. Subsequently, the reception levels are compared, and the base station with the highest reception level is set as the base station X to be connected to the line. In addition, when returning to step S30 from step S120, S130, S230, S240, the base station X already stored is compared with the base station with the highest reception level. Although the stored contents of the station storage unit 306 are not changed, when they are different, the base station newly recognized as the base station with the highest reception level is updated as the base station X.

次に、ステップＳ５０において、単位時間を単位時間設定部３０４に設定する。この設定は、待受動作中の単位時間ごとに受信レベル単位時間平均Ａを算定するためのものである。ここに、単位時間の設定は、ユーザがキーボード部４から入力するが、単位時間は、セル直径（基地局のサービス半径）が小さい都市部ほど小さく設定するとよい。また、受信レベルの棒グラフ表示を参照して、ユーザの経験に基づいて、設定してもよい。なお、デフォルト設定で待受動作を開始し、それでは不充分であるとき設定を変更してもよい。   In step S50, the unit time is set in the unit time setting unit 304. This setting is for calculating the reception level unit time average A for each unit time during the standby operation. Here, the setting of the unit time is input by the user from the keyboard unit 4, but the unit time may be set smaller as the city area has a smaller cell diameter (base station service radius). Further, it may be set based on the user's experience with reference to the bar graph display of the reception level. The standby operation may be started with default settings, and the settings may be changed when this is not sufficient.

続いて、ステップＳ６０において、受信レベル単位時間平均Ａを計算する。受信レベル単位時間平均Ａは、単位時間ごとに受信レベルを積分した値を単位時間で除算した値である。受信レベル単位時間平均Ａは、その値が小さい程、通信が途絶する可能性が高くなるため、通信を行うか否かの判断の目安となる。   Subsequently, in step S60, the reception level unit time average A is calculated. The reception level unit time average A is a value obtained by dividing the value obtained by integrating the reception level for each unit time by the unit time. The smaller the value of the reception level unit time average A, the higher the possibility that communication will be interrupted.

次に、ステップＳ７０において、着信拒否閾値Ｂが着信拒否閾値記憶部３１２に記憶される。ここに、着信拒否閾値Ｂの設定は、ユーザがキーボード部４から入力するが、例えば、受信レベルの棒グラフ表示を参照して、最大受信レベルの５％、１０％、１５％、２０％などの値を入力することとしてもよい。なお、デフォルト設定で待受動作を開始し、それでは不充分であるとき設定を変更してもよい。   Next, in step S <b> 70, the incoming call rejection threshold B is stored in the incoming call rejection threshold storage unit 312. Here, the setting of the incoming call rejection threshold B is input by the user from the keyboard unit 4. For example, referring to the bar graph display of the reception level, the maximum reception level is 5%, 10%, 15%, 20%, etc. A value may be input. The standby operation may be started with default settings, and the settings may be changed when this is not sufficient.

更に、ステップＳ８０において、上記Ａと上記Ｂが比較され、ＡがＢを超えない場合は、ステップＳ１００に進み、上記Ｂを記憶する。一方、ＡがＢを超える場合は、ステップＳ９０に進み、移動通信端末の位置情報〔ＧＰＳによる〕を通信相手に送信し、または通信相手の位置情報（通信相手のＧＰＳによる）を受信した後、ステップＳ１００に進み、上記Ｂを記憶する。戸のように、待受動作中に通信相手と位置情報の送信及び又は受信を行うのは、通話動作がなくても情報としての利用価値がある場合があるからである。なお、位置情報は通話動作（ステップＳ２２０）の前後で行うこともできる。   In step S80, A and B are compared. If A does not exceed B, the process proceeds to step S100 and B is stored. On the other hand, if A exceeds B, the process proceeds to step S90, where the position information of the mobile communication terminal (by GPS) is transmitted to the communication partner or the position information of the communication partner (by GPS of the communication partner) is received. In step S100, B is stored. The reason for transmitting and / or receiving position information with the communication partner during the standby operation as in the door is that there is a case where there is a use value as information even if there is no call operation. Note that the position information can also be performed before and after the call operation (step S220).

なお、移動通信端末がＧＰＳを内蔵していない場合（又はＧＰＳに接続されていない場合）は、ステップＳ８０、Ｓ９０は実行できないため、フローチャートからは削除される。   If the mobile communication terminal does not have a built-in GPS (or is not connected to the GPS), steps S80 and S90 cannot be executed, and are deleted from the flowchart.

次に、ステップＳ１１０において、上記Ａと上記Ｂが比較され、上記Ａが上記Ｂを超えない場合は、ステップＳ１３０に進み、着信拒否が着信拒否部３１１に記憶され、発信・着信部３０９は着信動作を行わない。また、この着信拒否は基地局Ｘに送信され、着信拒否を受信した基地局Ｘは、転送処理又は留守番電話処理を行う。これにより、着信に係る無駄な電力を節約する。一方、上記Ａが上記Ｂを超える場合は、ステップＳ１２０に進み、着信拒否（ステップＳ１２０、Ｓ２４０からステップＳ２０戻り再びＳ１２０に入った時）を解除する。この着信拒否解除は基地局Ｘに通知される。   Next, in step S110, A and B are compared. If A does not exceed B, the process proceeds to step S130, the incoming call rejection is stored in the incoming call rejection unit 311, and the outgoing / incoming part 309 receives the incoming call. No action is taken. The incoming call rejection is transmitted to the base station X, and the base station X receiving the incoming call rejection performs a transfer process or an answering machine process. This saves wasted power associated with incoming calls. On the other hand, if A exceeds B, the process proceeds to step S120, and the incoming call rejection (when returning from step S120, S240 to step S20 and entering S120 again) is cancelled. This incoming call rejection cancellation is notified to the base station X.

以上で待受け動作が一旦終了し、ステップＳ２０（操作判定）に戻る。このステップＳ２０は、着信拒否が解除されているときは、ステップＳ３０（待受動作ＳＴＡＲＴ）を再度選択し、着信拒否が記憶されているときは、ステップＳ２００（発信・着信動作ＳＴＡＲＴ）を選択するステップである。ステップＳ３０に続く処理は既に説明した。   Thus, the standby operation is temporarily terminated, and the process returns to step S20 (operation determination). In step S20, when the incoming call rejection is canceled, step S30 (standby operation START) is selected again, and when the incoming call rejection is stored, step S200 (outgoing / incoming operation START) is selected. It is a step. The process following step S30 has already been described.

そこで、ステップＳ２００（発信・着信動作ＳＴＡＲＴ）以降の処理について説明する。   Therefore, the processing after step S200 (outgoing / incoming operation START) will be described.

具体的には、ステップＳ２１０において,上記Ａは、上記Ｂを超えるか否かが判定される。その理由は、通信が頻繁に途絶する環境下では、ステップＳ１１０で上記Ａが上記Ｂ超をえていると判定されていても、その後の時刻において同じ判定結果になるとは限らず、判定結果が逆であれば、通話を開始しても中断される確率が高くなるからである。   Specifically, in step S210, it is determined whether or not A exceeds B. The reason for this is that in an environment where communication is frequently interrupted, even if it is determined in step S110 that A exceeds B, the determination result is not necessarily the same at subsequent times. If so, there is a higher probability of interruption even if a call is started.

そこで、ステップＳ２１０において、ＡがＢを超えないと判定されたときは、Ｓ２４０に進み、着信拒否を記憶するとともに、発信を禁止する。ステップＳ２４０における着信拒否は基地局Ｘに送信され、着信拒否を受信した基地局Ｘは、着信拒否に係る通信内容を転送先に転送するか、又は、留守番電話処理を行う。ステップＳ２４０実行後、ステップＳ２０へ戻るが、着信拒否が記憶されている状態であるため、ステップＳ３０（待受動作ＳＴＡＲＴ）がプログラムにより自動選択される。   Therefore, if it is determined in step S210 that A does not exceed B, the process proceeds to S240, where the incoming call rejection is stored and the outgoing call is prohibited. The incoming call rejection in step S240 is transmitted to the base station X, and the base station X that has received the incoming call rejection transfers the communication contents related to the incoming call rejection to the transfer destination or performs answering machine processing. After executing step S240, the process returns to step S20. However, since the incoming call rejection is stored, step S30 (standby operation START) is automatically selected by the program.

一方、ステップＳ２１０において、上記Ａが上記Ｂを超えるときは、通信が中断される虞が低いため、ステップＳ２２０へ進んで通話又はデータ送受信を行い、最後にステップＳ２３０に進んでキーボード部４の「終」キーを押下して終話処理を行う。そして、ステップＳ２０実行後、ステップＳ２０へ戻るが、終話処理状態であるため、ステップＳ３０（待受動作ＳＴＡＲＴ）がプログラムにより自動選択される。   On the other hand, when A exceeds B in step S210, the communication is unlikely to be interrupted, so the process proceeds to step S220 to perform a call or data transmission / reception, and finally to step S230 to “ Press the “End” key to perform the end speech processing. Then, after step S20 is executed, the process returns to step S20, but since it is in the end call processing state, step S30 (standby operation START) is automatically selected by the program.

図２を参照して説明した移動通信端末制御方法では、表示部５に棒グラフ表示される受信レベルを参照して着信拒否閾値を選択することができるよう、待受動作ＳＴＡＲＴ（ステップＳ３０）後に、着信拒否閾値Ｂ設定（ステップＳ７０）を実行した。しかし、これに限らず、ステップＳ７０をステップＳ３０の前に実行してもよい。   In the mobile communication terminal control method described with reference to FIG. 2, after the standby operation START (step S <b> 30), the reception rejection threshold can be selected with reference to the reception level displayed on the bar graph on the display unit 5. The incoming call rejection threshold B was set (step S70). However, the present invention is not limited to this, and step S70 may be executed before step S30.
