Description

本発明は、携帯電話機に関し、特に、ＧＰＳ（ＧｌｏｂａｌＰｏｓｉｔｉｏｎｉｎｇＳｙｓｔｅｍ）機能付きの携帯電話機に関する。 The present invention relates to a mobile phone, and more particularly to a mobile phone with a GPS (Global Positioning System) function.

ＧＰＳ機能付きの携帯電話機が知られている。ＧＰＳ機能により、ＧＰＳ衛星からの信号に基づいて携帯電話機の位置を算出する測位が実行される。ここで、信号が蓄積されて位置が算出される。信号の受信状態が悪い場合には、信号が十分に蓄積されるまで時間がかかるため、位置が算出されて測位が完了するまで時間がかかる。 A mobile phone with a GPS function is known. The GPS function performs positioning for calculating the position of the mobile phone based on a signal from a GPS satellite. Here, the signal is accumulated and the position is calculated. When the signal reception state is poor, it takes time until the signal is sufficiently accumulated, so it takes time until the position is calculated and the positioning is completed.

ＧＰＳ機能による測位中は、携帯電話機の他の機能の使用が制限される場合がある。そこで、タイムアウト時間が設定され、タイムアウト時間内に測位が完了しない場合には測位が中止される。 During positioning by the GPS function, use of other functions of the mobile phone may be restricted. Therefore, a timeout time is set, and positioning is stopped when positioning is not completed within the timeout time.

タイムアウト時間が短すぎると、測位が完了する確率が低くなる。タイムアウト時間が長すぎると、他の機能の使用が長時間制限されるため、携帯電話機の使い勝手が悪くなる。 If the timeout time is too short, the probability of completion of positioning is lowered. If the time-out time is too long, the use of other functions is restricted for a long time, and the usability of the mobile phone becomes poor.

特許文献１は、携帯電話機のような端末を開示している。端末は、太陽電池パネルと、ＧＰＳ装置とを備える。端末においては、太陽光発電量に基づいてサーチタイムアウト時間が変更される。サーチタイムアウト時間は、ＧＰＳ衛星を探索（サーチ）しても捕捉できない場合にサーチを中止するまでの時間を示す。 Patent Document 1 discloses a terminal such as a mobile phone. The terminal includes a solar cell panel and a GPS device. In the terminal, the search timeout time is changed based on the photovoltaic power generation amount. The search time-out time indicates a time until the search is stopped when the GPS satellite cannot be acquired even after searching (searching).

The GPS receiver starts positioning based on the signal from the GPS satellite, and stops positioning when positioning is not completed within the timeout time. The timeout time changing unit sets the timeout time to the first time when the housing is in the open state, and sets the timeout time to a second time longer than the first time when the housing is in the closed state.

添付図面を参照して、本発明の実施形態に係る携帯電話機を以下に説明する。 A mobile phone according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

（第１の実施形態）
図１は、本発明の第１の実施形態に係る携帯電話機を示す。携帯電話機は、折りたたみ式の筐体１０を備える。筐体１０は、第１筐体部分１１と、ヒンジ１３を介して第１筐体部分１１に接続された第２筐体部分１２を備える。第１筐体部分１１は、操作キー群が設けられた操作面１１ａを備える。第２筐体部分１２は、表示画面が設けられた表示面１２ａを備える。図１は、閉状態の筐体１０を示している、閉状態において、操作面１１ａ及び表示面１２ａが対向するように第１筐体部分１１及び第２筐体部分１２が重なっている。 (First embodiment)
FIG. 1 shows a mobile phone according to a first embodiment of the present invention. The mobile phone includes a foldable housing 10. The housing 10 includes a first housing portion 11 and a second housing portion 12 connected to the first housing portion 11 via a hinge 13. The 1st housing | casing part 11 is provided with the operation surface 11a in which the operation key group was provided. The second housing portion 12 includes a display surface 12a on which a display screen is provided. FIG. 1 shows the housing 10 in the closed state. In the closed state, the first housing portion 11 and the second housing portion 12 overlap so that the operation surface 11a and the display surface 12a face each other.

図２は、開状態の筐体１０を示している。開状態において、操作面１１ａ及び表示面１２ａがほぼ同じ方向を向くように、第１筐体部分１１及び第２筐体部分１２が開いている。 FIG. 2 shows the housing 10 in the open state. In the open state, the first housing portion 11 and the second housing portion 12 are opened so that the operation surface 11a and the display surface 12a face substantially the same direction.

携帯電話機は、二次電池を電源として備え、通話機能と、ＧＰＳ機能と、その他の機能を有する。ＧＰＳ機能により、ＧＰＳ衛星からの信号に基づいて携帯電話機の位置を算出する測位が実行される。ＧＰＳ機能による測位は、携帯電話機の現在位置を示す地図を表示画面に表示する現在位置確認、携帯電話機の移動経路のデータを取得するトラッキング、外部からの問い合わせに応答して携帯電話機の位置を示すデータを送信する第三者検索などのために実行される。 The mobile phone includes a secondary battery as a power source, and has a call function, a GPS function, and other functions. The GPS function performs positioning for calculating the position of the mobile phone based on a signal from a GPS satellite. Positioning by the GPS function indicates the current position of the mobile phone displayed on the display screen, tracking the current position of the mobile phone to acquire data on the moving path, and indicating the position of the mobile phone in response to an inquiry from the outside. It is executed for a third party search for transmitting data.

ＧＰＳ機能による測位は、筐体１０が開状態の場合にも閉状態の場合にも実行される。現在位置確認のための測位は、使用者による操作キー群の操作に応答して実行されるため、筐体１０が開状態のときに実行される。トラッキングや第三者検索のための測位は、筐体１０が閉状態のときに実行されることが少なくない。 Positioning by the GPS function is performed both when the housing 10 is in an open state and in a closed state. Since the positioning for confirming the current position is executed in response to the operation of the operation key group by the user, it is executed when the housing 10 is in the open state. Positioning for tracking and third-party search is often performed when the housing 10 is closed.

図３に示すように、携帯電話機は、ＧＰＳ機能のためのＧＰＳ受信機２０と、タイムアウト時間変更部３２と、開閉検出部３５と、通話機能のための図示されない無線送受信装置を備える。これらは、筐体１０に収容される。メモリ３１は、タイムアウト時間を示すデータを記憶する。ＧＰＳ受信機２０は、ＧＰＳエンジン２１と、ＧＰＳ回路２２を備える。ＧＰＳ回路２２は、ＧＰＳ衛星からの信号を受信するアンテナを備える。ＧＰＳエンジン２１は、信号に基づく測位を実行する。ＧＰＳエンジン２１は、測位を開始し、メモリ３１に記憶されたデータが示すタイムアウト時間内に測位が完了しない場合に測位を中止する。 As shown in FIG. 3, the mobile phone includes a GPS receiver 20 for the GPS function, a timeout time changing unit 32, an open / close detection unit 35, and a radio transmission / reception device (not shown) for the call function. These are accommodated in the housing 10. The memory 31 stores data indicating a timeout time. The GPS receiver 20 includes a GPS engine 21 and a GPS circuit 22. The GPS circuit 22 includes an antenna that receives a signal from a GPS satellite. The GPS engine 21 performs positioning based on the signal. The GPS engine 21 starts positioning, and stops positioning when positioning is not completed within the time-out time indicated by the data stored in the memory 31.

図４に示されるように、タイムアウト時間変更部３２によって参照されるテーブル３３は、筐体１０の開状態と時間Ｔ１とを対応付け、筐体１０の閉状態と時間Ｔ２とを対応付けている。時間Ｔ２は、時間Ｔ１より長い。 As shown in FIG. 4, the table 33 referred to by the timeout time changing unit 32 associates the open state of the housing 10 with the time T1, and associates the closed state of the housing 10 with the time T2. . Time T2 is longer than time T1.

図３を参照して、開閉検出部３５は、筐体１０の開閉状態を検出し、検出結果をタイムアウト時間変更部３２に出力する。タイムアウト時間変更部３２は、検出結果が筐体１０の開状態を示す場合、時間Ｔ１を示すデータをメモリ３１に記憶されているデータに上書きすることでタイムアウト時間を時間Ｔ１に設定する。また、タイムアウト時間変更部３２は、検出結果が筐体１０の閉状態を示す場合、時間Ｔ２を示すデータをメモリ３１に記憶されているデータに上書きすることでタイムアウト時間を時間Ｔ２に設定する。 Referring to FIG. 3, open / close detection unit 35 detects the open / close state of housing 10 and outputs the detection result to timeout time changing unit 32. When the detection result indicates the open state of the housing 10, the timeout time changing unit 32 sets the timeout time to the time T <b> 1 by overwriting the data indicating the time T <b> 1 with the data stored in the memory 31. Further, when the detection result indicates the closed state of the housing 10, the timeout time changing unit 32 sets the timeout time to the time T2 by overwriting the data stored in the memory 31 with the data indicating the time T2.

本実施形態によれば、筐体１０が開状態の場合にタイムアウト時間が短くなり、筐体１０が閉状態の場合にタイムアウト時間が長くなる。したがって、筐体１０が開状態の場合にＧＰＳ機能以外の機能の使用が長時間制限されることが防がれ、筐体１０が閉状態の場合に測位が完了する確率が高くなる。なお、筐体１０が閉状態の場合には、操作キー群の操作と表示画面を見ることとができないため、ＧＰＳ機能以外の機能の使用が長時間制限されても携帯電話機の使い勝手に影響は少ない。 According to the present embodiment, the time-out time is shortened when the housing 10 is in the open state, and the time-out time is long when the housing 10 is in the closed state. Therefore, the use of functions other than the GPS function is prevented from being restricted for a long time when the housing 10 is in the open state, and the probability that the positioning is completed when the housing 10 is in the closed state is increased. Note that when the case 10 is closed, the operation of the operation key group and the display screen cannot be seen, and thus the usability of the mobile phone is not affected even if the use of functions other than the GPS function is restricted for a long time. Few.

なお、ＧＰＳエンジン２１、タイムアウト時間変更部３２、開閉検出部３５の各々は、専用の電気回路により実現されてもよく、コンピュータプログラムに基づいて動作する演算処理装置により実現されてもよい。 Note that each of the GPS engine 21, the timeout time changing unit 32, and the open / close detection unit 35 may be realized by a dedicated electric circuit, or may be realized by an arithmetic processing device that operates based on a computer program.

（第２の実施形態）
図５に示すように、本発明の第２の実施形態に係る携帯電話機は、上述の筐体１０、ＧＰＳ受信機２０、メモリ３１、タイムアウト時間変更部３２、開閉検出部３５に加えて、動作検出部３６及びデバイス４０を備える。動作検出部３６及びデバイス４０は、筐体１０に収容される。タイムアウト時間変更部３２は、テーブル３３のかわりにテーブル３４を参照する。デバイス４０は、動作中にノイズを発生し、ＧＰＳ回路２２に悪影響を及ぼす抑圧源となる。デバイス４０としては、照度センサが例示される。照度センサによる照度の検出結果は、表示画面の明るさの調節などに利用される。デバイス４０が動作中は、ノイズのせいで、測位の完了までに時間がかかる。なお、デバイス４０は、照度センサに限定されない。 (Second Embodiment)
As shown in FIG. 5, the mobile phone according to the second embodiment of the present invention operates in addition to the case 10, the GPS receiver 20, the memory 31, the timeout time changing unit 32, and the open / close detection unit 35. A detection unit 36 and a device 40 are provided. The motion detection unit 36 and the device 40 are accommodated in the housing 10. The timeout time changing unit 32 refers to the table 34 instead of the table 33. The device 40 generates noise during operation and becomes a suppression source that adversely affects the GPS circuit 22. The device 40 is exemplified by an illuminance sensor. The detection result of the illuminance by the illuminance sensor is used for adjusting the brightness of the display screen. While the device 40 is operating, it takes time to complete positioning due to noise. The device 40 is not limited to an illuminance sensor.

図６に示すように、テーブル３４は、筐体１０が開状態且つデバイス４０が動作中でない（オフ状態である）場合と時間Ｔ１とを対応付け、筐体１０が閉状態且つデバイス４０が動作中でない場合と時間Ｔ２とを対応付け、筐体１０が開状態且つデバイス４０が動作中である（オン状態である）場合と時間Ｔ３とを対応付け、筐体１０が閉状態且つデバイス４０が動作中である場合と時間Ｔ４とを対応付けている。ここで、時間Ｔ２及びＴ３の各々は、時間Ｔ１より長い。時間Ｔ４は、時間Ｔ２及びＴ３のどちらよりも長い。時間Ｔ３は、時間Ｔ２より短くてもよく、同じでもよく、長くてもよい。 As shown in FIG. 6, the table 34 associates the time T1 with the case 10 in which the housing 10 is open and the device 40 is not operating (in the off state), and the device 10 is in the closed state and the device 40 operates. The case T2 is associated with the time T2, the case 10 is in the open state and the device 40 is operating (on state), and the time T3 is associated with the time T3. The case where it is operating is associated with time T4. Here, each of the times T2 and T3 is longer than the time T1. Time T4 is longer than both time T2 and T3. The time T3 may be shorter than the time T2, may be the same, or may be longer.

図５を参照して、動作検出部３６は、デバイス４０が動作中かどうかを検出し、検出結果をタイムアウト時間変更部３２に出力する。タイムアウト時間変更部３２は、開閉検出部３５からの検出結果が筐体１０の開状態を示し且つ動作検出部３６からの検出結果がデバイス４０が動作中でないことを示す場合、時間Ｔ１を示すデータをメモリ３１に記録されているデータに上書きすることでタイムアウト時間を時間Ｔ１に設定する。タイムアウト時間変更部３２は、開閉検出部３５からの検出結果が筐体１０の閉状態を示し且つ動作検出部３６からの検出結果がデバイス４０が動作中でないことを示す場合、時間Ｔ２を示すデータをメモリ３１に記録されているデータに上書きすることでタイムアウト時間を時間Ｔ２に設定する。タイムアウト時間変更部３２は、開閉検出部３５からの検出結果が筐体１０の開状態を示し且つ動作検出部３６からの検出結果がデバイス４０が動作中であることを示す場合、時間Ｔ３を示すデータをメモリ３１に記録されているデータに上書きすることでタイムアウト時間を時間Ｔ３に設定する。タイムアウト時間変更部３２は、開閉検出部３５からの検出結果が筐体１０の閉状態を示し且つ動作検出部３６からの検出結果がデバイス４０が動作中であることを示す場合、時間Ｔ４を示すデータをメモリ３１に記録されているデータに上書きすることでタイムアウト時間を時間Ｔ４に設定する。 Referring to FIG. 5, the operation detection unit 36 detects whether the device 40 is operating, and outputs the detection result to the timeout time changing unit 32. The time-out time changing unit 32 is data indicating time T1 when the detection result from the open / close detection unit 35 indicates the open state of the housing 10 and the detection result from the operation detection unit 36 indicates that the device 40 is not operating. Is overwritten on the data recorded in the memory 31 to set the timeout time to the time T1. The time-out time changing unit 32 is data indicating time T2 when the detection result from the open / close detection unit 35 indicates the closed state of the housing 10 and the detection result from the operation detection unit 36 indicates that the device 40 is not operating. Is overwritten on the data recorded in the memory 31 to set the timeout time to the time T2. The timeout time changing unit 32 indicates a time T3 when the detection result from the open / close detection unit 35 indicates the open state of the housing 10 and the detection result from the operation detection unit 36 indicates that the device 40 is operating. The time-out time is set to time T3 by overwriting the data recorded in the memory 31 with the data. The timeout time changing unit 32 indicates time T4 when the detection result from the open / close detection unit 35 indicates the closed state of the housing 10 and the detection result from the operation detection unit 36 indicates that the device 40 is operating. The time-out time is set to the time T4 by overwriting the data recorded in the memory 31.

本実施形態によれば、筐体１０が開状態の場合にタイムアウト時間が短くなり、筐体１０が閉状態の場合にタイムアウト時間が長くなることに加えて、デバイス４０が動作中でない場合にタイムアウト時間が短くなり、デバイス４０が動作中である場合にタイムアウト時間が長くなる。したがって、デバイス４０が動作中でない場合にＧＰＳ機能以外の機能の使用が長時間制限されることが防がれ、デバイス４０が動作中の場合に測位が完了する確率が低くなることが防がれる。 According to the present embodiment, the time-out time is shortened when the housing 10 is in the open state, the time-out time is long when the housing 10 is in the closed state, and the time-out occurs when the device 40 is not in operation. The time is reduced and the timeout time is increased when the device 40 is in operation. Therefore, it is possible to prevent the use of functions other than the GPS function from being restricted for a long time when the device 40 is not operating, and to prevent the probability of completion of positioning from being lowered when the device 40 is operating. .

第１筐体部分１１及び第２筐体部分１２の一方にＧＰＳ回路２２が配置され、他方にデバイス４０が配置されている場合、筐体１０が閉状態のときデバイス４０とＧＰＳ回路２２の距離が短く、筐体１０が開状態のときデバイス４０とＧＰＳ回路２２の距離が長い。デバイス４０とＧＰＳ回路２２の距離が短いほど、デバイス４０がＧＰＳ回路２２に及ぼす悪影響が大きいから、本実施形態は、第１筐体部分１１及び第２筐体部分１２の一方にＧＰＳ回路２２が配置され、他方にデバイス４０が配置されている場合に特に効果的である。また、ＧＰＳ回路２２とデバイス４０の両方が第１筐体部分１１及び第２筐体部分１２の一方に配置され、ＧＰＳ回路２２とデバイス４０が直近に実装されている場合も効果的である。 When the GPS circuit 22 is disposed on one of the first housing portion 11 and the second housing portion 12 and the device 40 is disposed on the other, the distance between the device 40 and the GPS circuit 22 when the housing 10 is closed. Is short and the distance between the device 40 and the GPS circuit 22 is long when the housing 10 is in the open state. As the distance between the device 40 and the GPS circuit 22 is shorter, the adverse effect of the device 40 on the GPS circuit 22 is greater. Therefore, in the present embodiment, the GPS circuit 22 is provided in one of the first housing portion 11 and the second housing portion 12. This is particularly effective when the device 40 is arranged on the other side. It is also effective when both the GPS circuit 22 and the device 40 are arranged in one of the first housing part 11 and the second housing part 12 and the GPS circuit 22 and the device 40 are mounted most recently.

なお、ＧＰＳエンジン２１、タイムアウト時間変更部３２、開閉検出部３５、動作検出部３６の各々は、専用の電気回路により実現されてもよく、コンピュータプログラムに基づいて動作する演算処理装置により実現されてもよい。 Each of the GPS engine 21, the timeout time changing unit 32, the open / close detection unit 35, and the operation detection unit 36 may be realized by a dedicated electric circuit, or by an arithmetic processing unit that operates based on a computer program. Also good.
