【発明の属する技術分野】
本発明は、移動体通信機の圏外と圏内との末端領域等における移動体通信機の動作に関し、特に移動体通信機の位置が停止状態にあるときに、圏外と圏内状態を繰り返す状態が続いた場合、圏外と判断する条件移行を極力抑える事により、不安定な末端領域等での無駄な電源の消費を抑制する機能を有する移動体通信機の動作に関する。
【０００２】
【従来の技術】
移動体通信機においては、受信電界レベルが圏内と圏外の境界位置（末端領域等）では、受信の電波状態が良くない。すなわちこのような末端領域等では、圏内状態基地局からの受信信号を受信する事が不可能になったり、あるいは基地局からの受信信号の受信が再び可能になったりするなどの状態変化をし、移動体通信機（移動端末または移動電話機）が前記末端領域等での状態で交互に前記状態の移行を繰返すなどの問題が発生し、これによって無駄に電力が消費されていた。
【０００３】
換言すれば、移動体通信機のこのような圏内と圏外の不安定な状態移行を移動体通信機自体が認識せずに動作すると、圏内と圏外の境界の位置では移動体通信機が移動しないにもかかわらず、圏内と圏外の状態移行を繰り返し、無駄な電力を消費し続けてしまう。
【０００４】
従来、たとえば特開平１０−１０７７１８号公報に記載されているように、移動体通信機の受信圏外に移ってからの移動を検出して携帯通信機の電源を自動で制御動作を行ったり、あるいは特開平１０−１７３５９０号公報に記載されているような条件により、圏外時の基地局サーチの間隔を変化させて制御動作を行うものが存在していた。
【０００５】
前記、特開平１０−１０７７１８号公報によれば、圏外に入ると圏外での無線部の電源を自動ＯＦＦする制御と、圏内に入ると自動ＯＮ制御することが特徴であり、圏内から圏外に移行する条件を開示したものではない。
【０００６】
また前記、特開平１０−１７３５９０号公報によれば、ある条件により圏外からの基地局サーチの時間間隔を変化させるものであり、圏内から圏外に移行する条件を開示してはいない。
【０００７】
【発明が解決しようとする課題】
従来の移動体通信機では、基地局からの受信電波が、圏内と圏外のレベルで変動する様な末端領域における位置では、移動体通信機が移動していない状態であっても、圏内・圏外の移行動作を繰り返すため、無駄な電力を消費する事になっていた。
【０００８】
本発明は、移動体通信機の移動を伴わずに、圏外状態と圏内状態との移行を繰り返す状態移行による無駄な電力の消費を低減する事を目的としている。すなわち本発明は、圏外と圏内の状態移行を、たとえば同じ基地局へ送信を繰り返して確認する場合、移動体通信機の移動を伴わずに状態移行することを自動的に検出し、移動体通信機の位置移動を伴わない状態で圏外と判断する判断条件を変えて圏外に状態移行することを極力抑制する事により、無駄な圏内←→圏外の状態移行を減らし、省電力を実現する事を目的としている。
【０００９】

【００１８】
【発明の実施の形態】
本発明による移動体通信機は、基地局からの受信信号を受信できなくなった事（圏外）、または、その逆に受信可能となった事（圏内）を検出する無線部と、現在、移動体通信機が移動を停止している状態か、移動している状態かを検出する移動センサー部とを有している。そして本発明による移動体通信機は、圏外と圏内に状態を移行する動作を、移動体通信機が移動を停止している状態で、同じ基地局相手に繰り返す事を検出した際に圏外に移行する条件を変更する制御部を有する構成となっている。
【００１９】
上記したような移行する条件と判断した場合には、圏内の状態で当該移動体通信機が受信している信号がとれなくなっても、圏外と判断する間隔を延長し、また、判定を行う際に用いられる受信電界レベルをさらに低くすることにより、圏内の状態に留まる条件を緩和し、圏外に移行しづらくする手段を有する。
【００２０】
第１実施形態
本発明の実施の形態について図面を参照して詳細に説明する。
図１を参照すると、本発明に係る移動体通信機の第１の実施形態は、現在の状態を有する情報を表示する表示部１と、基地局からの信号を受信する無線部２と、通信機全体の制御を行う制御部３と、通信機が停止状態か移動状態かを検出する移動センサー４とで構成されている。そして基地局からの電波が届く圏内か、電波が届かない圏外かを、無線部２により検出し、制御部３によって圏内か圏外かを判断する。このとき、通信機が移動を停止している状態か、または移動している状態かを、移動監視センサー４によって判断する。
【００２１】
移動監視センサー４によって、圏内に移行した時の条件で移動体通信機の移動停止状態が維持されているかを検出し、同じ基地局と受信が再開したのを制御部３により判断する。この判断は、任意の回数で繰返される。
【００２２】
このとき、移動体通信機が移動しておらず、かつ、同じ基地局との間で圏内状態に戻ったと判断された場合には、圏外と判断する条件を変更し、圏内の状態で受信している信号が再びとれなくなったときに、圏外と判断するまでの時間を延長し、圏外と判定する受信電界レベルしきい値を低くする。
【００２３】
図２は上記動作を表したフローチャートである。
図２に示すように、まず移動体通信機が圏外にある状態か否かを判断する（ステップＳ１）。そして圏内のとき（Ｎｏの場合）はステップＳ８を介して遷移回数をリセットし最初に戻る。また、圏外になった時に（ステップＳ１→ステップＳ２）、通信機が移動しているか否かの現状態をチェックし（ステップＳ２）、移動体通信機の位置が停止している状態になっていれば（ステップＳ２→ステップＳ３）、ステップＳ３に至って移動無しの状態を記憶する。また移動体通信機が移動している場合には、Ｓ８を介して圏内・圏外の移行回数をリセットし、最初に戻る。
【００２４】
次いで前記ステップＳ３は、以前と同じ基地局であるか否かを判断し（ステップＳ５）、同じ基地局である場合には（ステップＳ４→ステップＳ５）、移動体通信機が移動なしで圏外と圏外に遷移した回数が記憶され（ステップＳ６）、異なる基地局の場合には、前記どおり、ステップ８を介してリセットされて最初に戻る。
【００２５】
その後、変更しない場合には戻し（ステップＳ６→ステップＳ１）、圏内で受信している信号が再び受信不能となった場合に、圏外と判断されるまでの受信間隔を延長し、また、受信電界閾値レベルを低下させるなどの圏外判定条件を変更後（ステップＳ６→ステップＳ７、その後ステップＳ７→ステップＳ１）、再度この移動体通信機が以前と同一または異なる基地局の場合に、圏内であると検出されるときまで、移動体通信機の移動が検出されなければ、圏外の条件を変化させて圏内の状態に戻す。
この条件に当てはまらなければ、圏外条件は通常のまま、もしくは通常に戻す。なお本第１の実施形態において、ステップＳ３とステップＳ５での記憶した回数は好ましくは移動体通信機の異なる記憶部位に記憶してもよく、近似する部位に記憶してもよい。この記憶部位は、特に制限されず、場合によっては、移動体通信機以外に記憶部位を設けて通信等で連結させてこの値を知ることもできる。また、本実施形態では、特にステップＳ５での連続でおきた回数（ｎ１）に着目し、圏外判定の規定回数が前記ｎ１よりも小さいときに、条件変更を換えるようにすることができる。
【００２６】
次に本発明の移動体通信機の第１実施形態に係る動作について、説明する。
本発明の移動体通信機は、基地局からの信号を受信する無線部２により、基地局から電波が届かないエリアである圏外と検出された際、制御部３により圏外の判断を行い、制御部３により圏外と認識した場合に、移動監視センサー４を起動し、現在の通信機の移動状態を判別する。この移動監視センサで、移動体通信機の移動が停止している状態であると認識された場合、この認識した状態を制御部３で記憶し、圏外状態に移行する。その後、再度基地局２からの信号を受信する無線部により、基地局から電波が届くエリアである圏内と検出されるときまでに、移動監視センサー４によって移動体通信機の移動を検出しなかった場合、制御部３により、圏外と判断する条件を変更する。この圏外と判断する条件の変更は、特に制限なく、任意に設定できる値である。
【００２７】
また圏外と判断する条件における受信失敗回数を増加したり、受信電界レベルの最低レベル値をさらに低くする事は、制御部３によって適宜変更可能である。
この事により、圏外に移行することを極力制限し、電力の消費量を削減する事が可能となる。
【００２８】
この条件に当てはまらなければ、圏外条件は変化させず、通常のまま維持する。なお圏外条件を遷移回数の記憶をリセットすることに伴い、これを解除し、移動体通信機の位置の移動が無い状態の回数を保存し、この回数よりも一定数多くして（たとえば一定数として、前記回数をｎとしたとき、一定数は、ｎ＋１などを採用することができる。）、逐一、前記回数を増加させ、圏外条件を変化させるようにすることもできる。これは、第２実施形態でも同様であり、これらの条件は、適宜、設定可能である。
【００２９】
本発明による移動体通信機は、基地局からの受信信号を受信できなくなった事（圏外）を検出すると、現在移動体通信機の位置が停止している状態か、移動状態かをセンサー等の位置確認手段により判断する。
【００３０】
このあと、再び圏内に移行した時の条件で停止状態を維持したまま、圏外と判断する条件を変更する。また、圏内で受信している信号が再び受信できずに圏外に移行した場合に、圏外と判断するまでの受信失敗回数を増加し、受信間隔を延長し、また受信電界閾値レベルを低くする。
この圏内移行の条件を緩和した状態で、受信が維持できれば、圏内状態を維持する。
【００３１】
この事により、受信電界レベルが不安定なところで、移動体通信機が移動していない、しかも同一の基地局と圏外・圏内の遷移を繰返す場合、すなわち移動電話の位置が変わっていない場合の携帯通信機の状態を、通常より圏外と判断することを極力制限し、圏内・圏外の状態移行による無駄を少なくする。
【００３２】
第２実施形態
次に、本発明に係る移動体通信機の第２実施形態について説明する。
本第２実施形態において、使用される通信機の構造は、前記第１実施形態と同様である。
本実施形態では、移動体通信機が、位置を変えずに圏内・圏外の遷移を行う場合にあり、通信する基地局も変化する場合について対応可能となっている。
【００３３】
本第２実施形態は、図３のフローチャートに示すように、まず移動体通信機が圏外にある状態か否かを判断し（ステップＳ１１）、圏内の場合には、ステップＳ１８を介して戻り、また圏外になった場合には（ステップＳ１１→ステップＳ１２）、通信機が移動しているか否かの現状態をチェックする（ステップＳ１２）。このとき移動体通信機の位置が停止している状態になっていれば（ステップＳ１２→ステップＳ１３）、移動無しの状態（移動無しでの回数）を記憶し（ステップＳ１３）、移動体通信機が移動している場合にはステップＳ１８を介してリセットし、元に戻る（ステップＳ１２→ステップＳ１８→ステップＳ１１）。
【００３４】
次に移動無しの状態の前後で同じ基地局か否かを判断し同一基地局である場合には（ステップＳ１４→ステップＳ１５）、そのままステップＳ１５に進み、移動体通信機が位置を移動せずに、この位置のままで異なる基地局であることを確認した場合には、この異なる基地局も遷移回数を記録する新しい基地局として登録し（ステップＳ１９）、ステップＳ１５に進む。
【００３５】
その後、移動体通信機の位置の移動が無い状態で、圏外・圏内の遷移回数を記憶し（ステップＳ１５）、圏外判定条件を変更するか否か判断し（ステップＳ１６）、変更しない場合には戻し（ステップＳ１６→ステップＳ１１）、圏内で受信している信号が再び受信不能となった場合に、圏外と判断されるまでの受信間隔を延長し、また、受信電界閾値レベルを低下させるなどの圏外判定条件を変更後（ステップＳ１６→ステップＳ１７）、再度この移動体通信機が以前と同一または異なる基地局の場合に、圏内であると検出されるときまで、移動体通信機の移動が検出されなければ、圏外の条件を変化させて圏内の状態に戻す。
この条件に当てはまらなければ、圏外条件は通常のまま、もしくは通常に戻す。本第２の実施形態では、前記ステップＳ１１で、圏内と判断された場合、リセットして最初のステップＳ１１に戻り、以後、前記同様に進行するが、前記ステップＳ１１で、圏内と判断された場合、前記したような圏内・圏外の移行回数をリセットせずにこのまま回数を保存しておき（第１実施形態でのＳ１、Ｓ２およびＳ３なども同様）、ステップＳ１１に戻るようにすることもできる。また、圏内と判断された場合のみの圏内・圏外の移行回数を他の場所に記憶しておき、これを独立してリセットしたりすることもできる。これは、前記第１実施形態のステップＳ１〜Ｓ４でも同様である。
【００３６】
本発明による移動体通信機は、基地局からの受信信号を受信できなくなった事（圏外）を検出すると、現在移動体通信機の位置が停止している状態か、移動状態かをセンサー等の位置確認手段により判断する。
【００３７】
このあと、再び圏内に移行した時の条件で停止状態を維持したまま、圏外と判断する条件を変更する。また、圏内で受信している信号が再び受信できずに圏外に移行した場合に、圏外と判断するまでの受信失敗回数を増加し、受信間隔を延長し、また受信電界閾値レベルを低くする。
この圏内移行の条件を緩和した状態で、受信が維持できれば、圏内状態を維持する。
【００３８】
この事により、本第２実施形態においても、受信電界レベルが不安定なところで、移動体通信機が移動していない、すなわち移動電話の位置が変わっていない場合の携帯通信機の状態を、通常より圏外と判断することを極力制限し、圏内・圏外の状態移行による無駄を少なくすることができる。
【００３９】
【発明の効果】
本発明に係る移動体通信機によって、電界が不安定または微弱な位置での停止状態における節電効果が得られる。その理由は、基地局から電波が届いたり、届かなかったりを繰り返すエリア（末端領域）に、移動体通信機があることが検出された際、通信機が移動しているか否かの状態を判別し、停止状態であることが認識された場合に圏外と判断しづらくする事により、無駄な圏外・圏内の状態の遷移をなくす事による。
【００４０】
また本発明に係る移動体通信機によって、電界が不安定または微弱な位置で基地局が変更された場合でも前記同様の停止状態における節電効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to the operation of a mobile communication device in a terminal area between the out-of-service area and the in-service area of the mobile communication device, and in particular, when the position of the mobile communication device is in a stopped state, the state of repeating the out-of-service area and the in-service area state continues. In such a case, the present invention relates to the operation of a mobile communication device having a function of suppressing wasteful power consumption in an unstable end region or the like by minimizing the transition of conditions for determining out-of-service.
[0002]
[Prior art]
In the mobile communication device, the reception radio wave state is not good at the boundary position (terminal region or the like) where the reception electric field level is within and outside the range. That is, in such a terminal area, the state changes such that it is impossible to receive a reception signal from a base station in the area or reception of a reception signal from the base station becomes possible again. There has been a problem that the mobile communication device (mobile terminal or mobile telephone) alternately repeats the transition of the state in the state of the terminal area, etc., and this has wastefully consumed power.
[0003]
In other words, if the mobile communication device itself does not recognize such an unstable state transition between the mobile communication device and the outside of the service area, the mobile communication device does not move at the boundary between the service area and the outside of the service area. Nevertheless, the state transition between the inside and outside the area is repeated, and wasteful power continues to be consumed.
[0004]
Conventionally, for example, as described in Japanese Patent Application Laid-Open No. 10-107718, the movement after moving out of the reception range of the mobile communication device is detected and the power supply of the portable communication device is automatically controlled, or There exist some which perform control operation by changing the interval of base station search when out of service area under the conditions described in Japanese Patent Laid-Open No. 10-173590.
[0005]
According to the above-mentioned Japanese Patent Application Laid-Open No. 10-107718, it is characterized in that the power of the wireless unit outside the service area is automatically turned off when entering the outside of the service area, and the automatic ON control is performed when entering the service area. It does not disclose the conditions to do.
[0006]
In addition, according to Japanese Patent Laid-Open No. 10-173590, the time interval for base station search from outside the service area is changed according to a certain condition, and the condition for shifting from the service area to the service area is not disclosed.
[0007]
[Problems to be solved by the invention]
In a conventional mobile communication device, even if the mobile communication device is not moving at a position in the end region where the radio wave received from the base station fluctuates between the range and the level outside the range, In order to repeat the transition operation, wasteful power was consumed.
[0008]
An object of the present invention is to reduce wasteful power consumption due to a state transition in which a transition between an out-of-service state and a within-service state is repeated without moving a mobile communication device. That is, the present invention automatically detects a state transition without movement of a mobile communication device, for example, when repeatedly checking the state transition between out-of-range and within-range, for example, by repeatedly transmitting to the same base station. By changing the judgment conditions for judging that the aircraft is out of service without changing the position of the aircraft and suppressing the status transition to the out of service area as much as possible, it is possible to reduce wasteful coverage ← → out of service status and realize power saving. It is aimed.

DETAILED DESCRIPTION OF THE INVENTION
The mobile communication device according to the present invention includes a radio unit for detecting that a received signal from a base station cannot be received (out of service area), or vice versa (in service area), and a mobile unit And a movement sensor unit that detects whether the communication device has stopped moving or is moving. When the mobile communication device according to the present invention detects that the mobile communication device repeats the same base station partner in the state where the mobile communication device stops moving, it moves out of the range. It has composition which has a control part which changes conditions to do.
[0019]
When it is determined that the conditions for shifting are as described above, even if the signal received by the mobile communication device in the range is not available, the interval for determining that the mobile communication device is out of range is extended and the determination is performed. By further lowering the reception electric field level used for the mobile phone, there is a means for relaxing the condition of staying in the area and making it difficult to move out of the area.
[0020]
First Embodiment An embodiment of the present invention will be described in detail with reference to the drawings.
Referring to FIG. 1, a mobile communication device according to a first embodiment of the present invention includes a display unit 1 that displays information having a current state, a radio unit 2 that receives a signal from a base station, and a communication. A control unit 3 that controls the entire machine and a movement sensor 4 that detects whether the communication apparatus is in a stopped state or a moving state. Then, the wireless unit 2 detects whether the radio wave from the base station is within range or out of range where the radio wave does not reach, and the control unit 3 determines whether the radio wave is out of range. At this time, the movement monitoring sensor 4 determines whether the communication device has stopped moving or is moving.
[0021]
The movement monitoring sensor 4 detects whether or not the mobile communication device has stopped moving under the conditions at the time of moving to the area, and the control unit 3 determines that reception with the same base station has been resumed . This determination is repeated any number of times.
[0022]
At this time, if it is determined that the mobile communication device is not moving and has returned to the in-range state with the same base station, the condition for determining out-of-range is changed, and reception is performed in the in-range state. when it is signal Tsu no longer taken again, to extend the time until it is determined that the out of range, to reduce the out-of-service and determines received field level threshold.
[0023]
FIG. 2 is a flowchart showing the above operation.
As shown in FIG. 2, it is first determined whether or not the mobile communication device is out of range (step S1). And when it is in the range (in the case of No), the number of transitions is reset via step S8 and the process returns to the beginning. Moreover, when it becomes out of service area (step S1 → step S2), the current state of whether or not the communication device is moving is checked (step S2), and the position of the mobile communication device is stopped. If so (Step S2 → Step S3), the process reaches Step S3 and stores the state of no movement. When the mobile communication device is moving, the number of transitions within / out of service area is reset via S8, and the process returns to the beginning.
[0024]
Next, in step S3, it is determined whether or not the base station is the same as before (step S5). If the base station is the same (step S4 → step S5), the mobile communication device is moved out of service without moving. The number of times of transitioning out of service is stored (step S6), and in the case of a different base station, as described above, it is reset via step 8 and returns to the beginning.
[0025]
After that, if it is not changed, it is returned (step S6 → step S1). When the signal received in the area becomes unreceivable again, the reception interval until it is determined that it is out of the area is extended. After changing out-of-range determination conditions such as lowering the threshold level (step S6 → step S7, then step S7 → step S1), if this mobile communication device is again the same or different base station as before, it is within range If the movement of the mobile communication device is not detected until it is detected, the out-of-service condition is changed to return to the in-service state.
If this condition is not met, the out-of-service condition remains normal or returns to normal. In the first embodiment, the number of times stored in step S3 and step S5 may be preferably stored in a different storage part of the mobile communication device or may be stored in an approximate part. This storage part is not particularly limited, and in some cases, this value can be obtained by providing a storage part other than the mobile communication device and connecting it by communication or the like. Further, in the present embodiment, focusing on the number of consecutive times (n1) in step S5, the condition change can be changed when the prescribed number of out-of-service determinations is smaller than n1.
[0026]
Next, the operation | movement which concerns on 1st Embodiment of the mobile communication apparatus of this invention is demonstrated.
In the mobile communication device of the present invention, when the wireless unit 2 that receives a signal from the base station detects that the radio wave is not reachable from the base station, the control unit 3 determines the out-of-service area and performs control. When the unit 3 recognizes that it is out of range, the movement monitoring sensor 4 is activated to determine the current movement state of the communication device. When the movement monitoring sensor recognizes that the movement of the mobile communication device is stopped, the recognized state is stored in the control unit 3, and the state shifts to the out-of-service state. After that, the movement of the mobile communication device was not detected by the movement monitoring sensor 4 until the wireless unit that receives the signal from the base station 2 again detects that the area is an area where radio waves reach from the base station. In this case, the control unit 3 changes the condition for determining out of range. The change of the condition for determining out of range is a value that can be arbitrarily set without any particular limitation.
[0027]
Further, it is possible to appropriately change the control unit 3 to increase the number of reception failures under the condition for determining out of range or further lower the minimum level value of the received electric field level.
As a result, it is possible to limit the transition to outside the service area as much as possible and to reduce the power consumption.
[0028]
If this condition is not applied, the out-of-service condition is not changed and is maintained as usual. The out-of-service condition is canceled by resetting the memory of the number of transitions, and the number of times that the position of the mobile communication device is not moved is saved, and a certain number of times (for example, as a constant number) is stored. , Where n is the number of times, n + 1 or the like can be adopted as the fixed number.) The out-of-service condition can be changed by increasing the number of times. This also applies to the second embodiment, and these conditions can be set as appropriate.
[0029]
When the mobile communication device according to the present invention detects that the reception signal from the base station cannot be received (out of service area), the mobile communication device determines whether the position of the mobile communication device is currently stopped or is in a moving state, such as a sensor. This is determined by the position confirmation means.
[0030]
Thereafter, the condition for determining that the vehicle is out of the service area is changed while the stop state is maintained under the condition when the vehicle moves into the service area again. In addition, when a signal received in the area cannot be received again and shifts to the outside of the area, the number of reception failures until the signal is determined to be out of the area is increased, the reception interval is extended, and the reception electric field threshold level is lowered.
If reception can be maintained in a state in which the conditions for transition to the area are relaxed, the area state is maintained.
[0031]
As a result, the mobile phone is not moving when the received electric field level is unstable, and the mobile phone does not move and repeats transitions between the same base station and out-of-service area, that is, when the mobile phone position has not changed. Limiting the state of the communication device to be out of range as much as possible as much as possible, and reducing waste due to state transitions within and outside the range.
[0032]
Second Embodiment Next, a second embodiment of the mobile communication device according to the present invention will be described.
In the second embodiment, the structure of the communication device used is the same as that of the first embodiment.
In the present embodiment, the mobile communication device may be in the case of making a transition between the in-range and out-of-range without changing the position, and the case where the base station for communication changes also can be handled.
[0033]
In the second embodiment, as shown in the flowchart of FIG. 3, it is first determined whether or not the mobile communication device is out of the service area (step S11), and if it is within the service area, the process returns via step S18. In addition, when it is out of service area (step S11 → step S12), the current state of whether or not the communication device is moving is checked (step S12). At this time, if the position of the mobile communication device is stopped (step S12 → step S13), the state of no movement (number of times of no movement) is stored (step S13), and the mobile communication apparatus is stored. If is moving, it is reset via step S18 and returns to the original (step S12 → step S18 → step S11).
[0034]
Next, it is determined whether or not they are the same base station before and after the state of no movement. If they are the same base station (step S14 → step S15), the process proceeds to step S15 and the mobile communication device does not move its position. If it is confirmed that the base station is different at this position, the different base station is also registered as a new base station for recording the number of transitions (step S19), and the process proceeds to step S15.
[0035]
Thereafter, in a state where the position of the mobile communication device is not moved, the number of transitions between out-of-range / in-range is stored (step S15), it is determined whether or not to change the out-of-range determination condition (step S16). Return (step S16 → step S11), when the signal received in the area becomes unreceivable again, the reception interval until it is determined that the signal is out of the area is extended, and the reception electric field threshold level is lowered. After changing the out-of-service determination condition (step S16 → step S17), the mobile communication device is detected to move again until it is detected that the mobile communication device is in the same area when the mobile communication device is the same or different from the previous base station. If not, change the out-of-service condition back to the in-service state.
If this condition is not met, the out-of-service condition remains normal or returns to normal. In the second embodiment, if it is determined in step S11 that the user is in the range, the process is reset and the process returns to the first step S11. Thereafter, the process proceeds in the same manner as described above, but the user is determined to be in the range in step S11. It is also possible to store the number of times as it is without resetting the number of times of transition within / out of the range as described above (the same applies to S1, S2, and S3 in the first embodiment) and return to step S11. . In addition, the number of transitions within or outside the range only when it is determined to be within the range can be stored in another place, and this can be reset independently. The same applies to steps S1 to S4 of the first embodiment.
[0036]
When the mobile communication device according to the present invention detects that the reception signal from the base station cannot be received (out of service area), the mobile communication device determines whether the position of the mobile communication device is currently stopped or is in a moving state, such as a sensor. This is determined by the position confirmation means.
[0037]
Thereafter, the condition for determining that the vehicle is out of the service area is changed while the stop state is maintained under the condition when the vehicle moves into the service area again. In addition, when a signal received in the area cannot be received again and shifts to the outside of the area, the number of reception failures until the signal is determined to be out of the area is increased, the reception interval is extended, and the reception electric field threshold level is lowered.
If reception can be maintained in a state in which the conditions for transition to the area are relaxed, the area state is maintained.
[0038]
As a result, also in the second embodiment, the state of the mobile communication device when the mobile communication device is not moving at the place where the reception electric field level is unstable, that is, the position of the mobile phone has not changed, is It is possible to limit the determination of being out of service area as much as possible, and to reduce waste due to the state transfer between service area and out of service area.
[0039]
【The invention's effect】
With the mobile communication device according to the present invention, a power saving effect in a stopped state at a position where the electric field is unstable or weak can be obtained. The reason for this is that when it is detected that there is a mobile communication device in the area (terminal area) where radio waves arrive and do not reach the base station, it is determined whether or not the communication device is moving. In addition, when it is recognized that the vehicle is in a stopped state, it is difficult to determine that it is out of service area, thereby eliminating useless transition between out of service area and service area.
[0040]
Further, the mobile communication device according to the present invention can provide the same power saving effect in the stop state as described above even when the base station is changed at a position where the electric field is unstable or weak.
