【発明の属する技術分野】
本発明は携帯電話装置及びそれに用いる異種網切替え方法並びにそのプログラムに関し、特に各々異なる通信方式を用いる2種類以上の無線網に対応する携帯電話移動機における通信網の切替え方法に関する。
【0002】
【従来の技術】
従来、この種の携帯電話移動機においては、PDC(Personal Digital Cellular)、PHS(Personal Handy−phone System)、CDMA(Code Division Multiple Access)、W−CDMA(Wideband−CDMA)等の異なる通信方式を用いる2種類以上の無線網に対応している。上記の携帯電話移動機では、無線網の切替えのトリガが無線網側から報知される情報や圏外によって行われている。
【0003】
上記の携帯電話移動機の構成例を図3に示す。図3において、携帯電話移動機は無線網#1制御部1と、無線網#2制御部2と、CPU(中央処理装置)(#3)3と、メモリ(#3)5と、切替回路6と、表示部7と、キー部8と、音声LSI(大規模集積回路)9と、スピーカ10とから構成されている。
【0004】
無線網#1制御部1はアンテナ11と、無線部(#1)12と、ベースバンド制御部(#1)13と、CPU(#1)14と、メモリ(#1)15とからなり、無線網#2制御部2はアンテナ21と、無線部(#2)22と、ベースバンド制御部(#2)23と、CPU(#2)24と、メモリ(#2)25とからなっている。
【0005】
上記の構成の携帯電話移動機では、図4に示すような動作を行うことで、図示せぬ無線網の切替えが行われている。以下、図示せぬ無線網#1,#2の切替え動作について説明する。
【0006】
携帯電話移動機では、まず無線網#1の待受けを行っており(図4ステップS11)、無線網#2からの受信可能情報を受信するか、あるいは無線網#1の圏外になると(図4ステップS12)、その旨がCPU(#1)14からCPU(#3)3に通知される(図4ステップS13)。
【0007】
携帯電話移動機ではCPU(#3)3がCPU(#1)14を停止させ、CPU (#2)24への切替え起動を行う(図4ステップS14)。この後に、携帯電話移動機は無線網#2の待受けを行う(図4ステップS15)。
【0008】
携帯電話移動機は無線網#1からの受信可能情報を受信するか、あるいは無線網#2の圏外になると(図4ステップS16)、その旨がCPU(#2)24からCPU(#3)3に通知される(図4ステップS17)。
【0009】
携帯電話移動機ではCPU(#3)3がCPU(#2)24を停止させ、CPU (#1)14への切替え起動を行う(図4ステップS18)。この後に、携帯電話移動機はステップS11に戻って無線網#2の待受けを行う。
【0010】
【発明が解決しようとする課題】
上述した従来の携帯電話移動機では、無線網の切替えのトリガが無線網側から報知される情報や圏外によって行われているので、その切替えがエリア端や電波状態が不安定な場所で頻繁に起こる可能性があり、消費電流の増大や切替え時のデッドタイム増大といった悪影響が考えられる。
【0011】
そこで、本発明の目的は上記の問題点を解消し、使用時間の延長及び使い勝手の向上を図ることができる携帯電話装置及びそれに用いる異種網切替え方法並びにそのプログラムを提供することにある。
【0012】
【課題を解決するための手段】
本発明による携帯電話装置は、各々異なる通信方式を用いる2種類以上の無線網に対応し、電波によって報知される情報と圏内及び圏外を示す情報とに応じて前記2種類以上の無線網を切替えて使用する携帯電話装置であって、
自端末の移動の有無を検知する検知手段と、前記2種類以上の無線網の切替え時において前記検知手段の検知結果と前記電波によって報知される情報と前記圏内及び圏外を示す情報とを基に前記無線網の切替えを制御する制御手段とを備え
前記制御手段は、前記検知手段で自端末の振動が検知された時に前記無線網の切替えを行い、前記検知手段で自端末の振動が検知されない時に前記無線網の切替えを抑止している。
【0013】
本発明による異種網切替え方法は、各々異なる通信方式を用いる2種類以上の無線網に対応し、電波によって報知される情報と圏内及び圏外を示す情報とに応じて前記2種類以上の無線網を切替えて使用する携帯電話装置に用いる異種網切替え方法であって、
前記携帯電話装置の振動を検知する検知手段で当該振動の有無を確認するステップと、前記2種類以上の無線網の切替え時において前記検知手段の検知結果と前記電波によって報知される情報と前記圏内及び圏外を示す情報とを基に前記無線網の切替えを制御するステップとを備え
前記無線網の切替えを制御するステップにおいて、前記検知手段で自端末の振動が検知された時に前記無線網の切替えを行い、前記検知手段で自端末の振動が検知されない時に前記無線網の切替えを抑止している。
【0014】
本発明によるプログラムは、各々異なる通信方式を用いる2種類以上の無線網に対応し、電波によって報知される情報と圏内及び圏外を示す情報とに応じて前記2種類以上の無線網を切替えて使用する携帯電話装置内のコンピュータに実行させるプログラムであって、
前記携帯電話装置の振動を検知する検知手段で当該振動の有無を確認する処理と、前記2種類以上の無線網の切替え時において前記検知手段の検知結果と前記電波によって報知される情報と前記圏内及び圏外を示す情報とを基に前記無線網の切替えを制御する処理とを含み、
前記無線網の切替えを制御する処理において、前記検知手段で自端末の振動が検知された時に前記無線網の切替えを行わせ、前記検知手段で自端末の振動が検知されない時に前記無線網の切替えを抑止させることを特徴とする
【0015】
すなわち、本発明の携帯電話装置は、2種類以上の異種携帯電話ネットワークに対応し、個々を自動的に切替える機能を持つ携帯電話装置において、その自動切換えのトリガを振動検出による移動中か静止中かの判断に則り、静止中の場合、消費電力低減のために網切替えを抑制し、移動中の場合、積極的に切替えを行うようにしている。ここで、「静止中」とは端末が充電中や端末を収納する物が静止状態にあることを指している。
【0016】
従来の網の切替え方法では、網の切替えが電波によって報知される情報や、電界強度等の圏内外情報によって行われているが、この方法ではエリア端や電波状態が不安定な状況において、移動機内での網制御部の切替えが頻繁に行われ、切替えに要する時間が問題になったり、消費電流が増大する等の悪影響がある。
【0017】
これに対し、本発明の携帯電話装置では、移動機が移動中かどうかを網の切替えの判断材料に加えることによつて、移動中であれば最適な網になるように網切替えを積極的に行い、静止中であれば網切替えを抑制することで、網切替えの際に生じる消費電流を抑え、あるいは切替え時のデッドタイムを少なくすることが可能となる。これによって、本発明の携帯電話装置では、使用時間の延長及び使い勝手の向上を図ることが可能となる。
【0018】
【発明の実施の形態】
次に、本発明の実施例について図面を参照して説明する。図1は本発明の一実施例による携帯電話装置の詳細な構成を示すブロック図である。図1において、本発明の一実施例による携帯電話装置は無線網#1制御部1と、無線網#2制御部2と、CPU(#3)3と、振動センサ4と、メモリ(#3)5と、切替回路6と、表示部7と、キー部8と、音声LSI(大規模集積回路)9と、スピーカ10とから構成されている。
【0019】
無線網#1制御部1はアンテナ11と、無線部(#1)12と、ベースバンド制御部(#1)13と、CPU(#1)14と、メモリ(#1)15とを含んで構成され、無線網#2制御部2はアンテナ21と、無線部(#2)22と、ベースバンド制御部(#2)23と、CPU(#2)24と、メモリ(#2)25とを含んで構成されている。
【0020】
無線網#1制御部1は図示せぬ無線網#1の制御を行い、無線網#2制御部2は図示せぬ無線網#2の制御を行う。中央処理制御部3は無線網#1,#2相互の切替え(切替回路6による無線網#1制御部1及び無線網#2制御部2の切替え)を集中して制御する。振動センサ4は自装置が移動中であるかどうかを判別するための振動を検出する。
【0021】
ここで、無線網#1,#2はPDC(Personal Digital Cellular)、PHS(Personal Handy−phone System)、CDMA(Code Division Multiple Access)、W−CDMA(Wideband−CDMA)等の異なる通信方式を用いる無線網である。例えば、無線網#1の通信方式を「PDC」とし、無線網#2の通信方式を「PHS」または「W−CDMA」とするような場合が考えられる。
【0022】
2種類以上の無線網に対応する従来の携帯電話移動機では、それぞれの網から報知される情報によって、現在使用中の網から他の網に接続可能か、もしくは現在使用中の網の圏外の情報をトリガとし、他の網への接続に切替えている。
【0023】
これに対し、本実施例では、他の網への切替えのトリガをCPU(#3)3が認知した場合、振動センサ4で振動が検出されていれば、自端末が移動中であると判断し、網が切替わった可能性が高く、網の切替えを即時に行う等の積極的な切替えを行う。
【0024】
CPU(#3)3は振動センサ4で振動が検出されていなければ、移動していないと判断し、外部要因にて網の圏外またはエリア端によって別情報が報知された可能性が高いため、網の切替えを行わず、現在使用中の網への接続を継続する。
【0025】
図3は本発明の一実施例による携帯電話装置の網の切替え処理を示すフローチャートである。これら図2及び図3を参照して本発明の一実施例による携帯電話装置での網の切替え処理について説明する。
【0026】
尚、図3に示す切替え処理は無線網#1から無線網#2への切替え動作を示しており、無線網#2から無線網#1への切替えも図3に示す切替え処理と同様にして行われる。また、図3に示す切替え処理はCPU(#3)3がメモリ(#3)5に格納されてプログラムを実行することで実現される。
【0027】
本発明の一実施例による携帯電話装置では、まず内部カウンタ(図示せず)の初期設定(=0)とし(図3ステップS1)、無線網#1の待受けを行っており(図3ステップS2)、無線網#2からの受信可能情報を受信するか、あるいは無線網#1の圏外になると(図3ステップS3)、その旨がCPU(#1)14からCPU(#3)3に通知される(図3ステップS4)。
【0028】
CPU(#3)3はCPU(#1)14からの通知を受けると、振動センサ4を確認し(図3ステップS5)、振動を検知するか、または振動量が大であれば、移動中である確率が大であるため、従来と同様に、CPU(#1)14を停止させ、CPU(#2)24への切替え起動を行う(図3ステップS9)。この後に、携帯電話装置は無線網#2の待受けを行う(図3ステップS10)。
【0029】
一方、CPU(#3)3は振動がないか、または振動量が小であれば、静止中である確率が大であるため、一定時間(例えば、A秒間)待ち(切替え処理そのものを停止させ)(図3ステップS6)、内部カウンタをカウントアップ(+1)し(図3ステップS7)、内部カウンタの値が所定値B以上でなければ(図3ステップS8)、ステップS2に戻って無線網#1の待受けを行う。ここで、「静止中」とは端末が充電中や端末を収納する物が静止状態にあることを指している。
【0030】
CPU(#3)3は内部カウンタの値が所定値B以上になると(図3ステップS8)、従来と同様に、CPU(#1)14を停止させ、CPU(#2)24への切替え起動を行う(図3ステップS9)。この後に、携帯電話装置は無線網#2の待受けを行う(図3ステップS10)。
【0031】
すなわち、振動センサ4で振動が検知されなければ、自装置が移動しておらず、基地局(図示せず)の切替えが生じたわけではないので、無線網#1の待受けに戻り、無線網#2からの受信可能情報を受信するか、あるいは無線網#1の圏外になるのを待つ。
【0032】
また、上記の一定時間待ったり、内部カウンタの値のチェックは振動センサ4で振動が検知されない時に、同じ処理を短時間で繰り返すことで消費電力がアップするのを抑制したり、ほとんど信号を検知することなく基地局が切替わる場合に網の切り替えを本当に行う必要があるので、リトライアウトを行うために設けている。
【0033】
このように、本実施例では、自装置の振動を検出し、移動機が移動中かどうかを判断材料に加えることによって、移動中であれば最適な網になるように網の切替えを積極的に行い、静止中であれば網の切替えを抑制することで、網の切替えの際に生じる消費電流を抑え、または網の切替え時のデッドタイムを少なくすることができるので、移動機の使用時間の延長及び使い勝手の向上を図ることができる。
【0034】
これによって、従来の切替え方法における、網の切替えが電波によって報知される情報や電界強度等の圏内外情報によって切替えを行うことで、エリア端や電波状態が不安定な状況で、移動機内での網制御部の切替えが頻繁に行われ、切替えに要する時間が問題になったり、消費電流が増大する等の悪影響が生ずるのを抑止することができる。
【0035】
尚、本実施例では、振動検出の判断基準として、振動のある・なしだけでなく、振動していた時間をもパラメータにすることによって、多く移動していた場合とわずかな移動であった場合とを判別し、少量の移動であった場合に網の切替えの積極度を抑えることで、より実使用に近いものとして実施することができる。
【0036】
【発明の効果】
以上説明したように本発明は、各々異なる通信方式を用いる2種類以上の無線網に対応し、2種類以上の無線網を切替えて使用する携帯電話装置において、2種類以上の無線網の切替え時に自端末の振動を検知する検知手段で当該振動の有無を確認し、検知手段の検知結果を基に無線網の切替えを制御することによって、使用時間の延長及び使い勝手の向上を図ることができるという効果が得られる。

[0010]
[Problems to be solved by the invention]
In the conventional mobile phone mobile device described above, the trigger for switching the wireless network is performed by information notified from the wireless network side or out of service area, so the switching is frequently performed at the edge of the area or where the radio wave condition is unstable. There is a possibility that this will occur, and adverse effects such as an increase in current consumption and an increase in dead time at the time of switching can be considered.
[0011]
Accordingly, an object of the present invention is to provide a mobile phone device which can solve the above-mentioned problems and can extend the use time and improve the usability, a heterogeneous network switching method used therefor, and a program therefor.
[0012]

The control means performs switching of the wireless network when vibration of the terminal is detected by the detection means, and suppresses switching of the wireless network when vibration of the terminal is not detected by the detection means .
[0013]
The heterogeneous network switching method according to the present invention corresponds to two or more types of wireless networks using different communication methods, and the two or more types of wireless networks are set in accordance with information notified by radio waves and information indicating in-range and out-of-range. a heterogeneous network switching method for use in a mobile telephone apparatus used by switching,

[0018]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a detailed configuration of a cellular phone device according to an embodiment of the present invention. In FIG. 1, a mobile phone device according to an embodiment of the present invention includes a wireless network # 1 control unit 1, a wireless network # 2 control unit 2, a CPU (# 3) 3, a vibration sensor 4, and a memory (# 3). ) 5, a switching circuit 6, a display unit 7, a key unit 8, an audio LSI (Large Scale Integrated Circuit) 9, and a speaker 10.
[0019]
The wireless network # 1 control unit 1 includes an antenna 11, a wireless unit (# 1) 12, a baseband control unit (# 1) 13, a CPU (# 1) 14, and a memory (# 1) 15. The wireless network # 2 control unit 2 includes an antenna 21, a wireless unit (# 2) 22, a baseband control unit (# 2) 23, a CPU (# 2) 24, and a memory (# 2) 25. It is comprised including.
[0020]
The radio network # 1 control unit 1 controls the radio network # 1 (not shown), and the radio network # 2 control unit 2 controls the radio network # 2 (not shown). The central processing control unit 3 centrally controls switching between the wireless networks # 1 and # 2 (switching between the wireless network # 1 control unit 1 and the wireless network # 2 control unit 2 by the switching circuit 6). The vibration sensor 4 detects vibration for determining whether or not the own device is moving.
[0021]
Here, the wireless networks # 1 and # 2 use different communication methods such as PDC (Personal Digital Cellular), PHS (Personal Handy-phone System), CDMA (Code Division Multiple Access), and W-CDMA (Wideband-CDMA). It is a wireless network. For example, the communication system of the wireless network # 1 may be “PDC”, and the communication system of the wireless network # 2 may be “PHS” or “W-CDMA”.
[0022]
In the conventional mobile phone mobile device that supports two or more types of wireless networks, it is possible to connect from the currently used network to another network, or outside the service area of the currently used network, depending on information broadcast from each network. Information is used as a trigger to switch to connection to another network.
[0023]
On the other hand, in this embodiment, when the CPU (# 3) 3 recognizes a trigger for switching to another network, if vibration is detected by the vibration sensor 4, it is determined that the terminal is moving. However, there is a high possibility that the network has been switched, and active switching such as switching the network immediately is performed.
[0024]
If vibration is not detected by the vibration sensor 4, the CPU (# 3) 3 determines that it is not moving, and there is a high possibility that other information is notified by the outside of the network or the end of the area due to an external factor. Continue to connect to the currently used network without switching the network.
[0025]
FIG. 3 is a flowchart showing the network switching process of the cellular phone device according to one embodiment of the present invention. With reference to FIG. 2 and FIG. 3, the network switching process in the cellular phone device according to the embodiment of the present invention will be described.
[0026]
3 shows the switching operation from the wireless network # 1 to the wireless network # 2, and the switching from the wireless network # 2 to the wireless network # 1 is performed in the same manner as the switching process shown in FIG. Done. The switching process shown in FIG. 3 is realized by the CPU (# 3) 3 being stored in the memory (# 3) 5 and executing the program.
[0027]
In the mobile phone device according to the embodiment of the present invention, first, an internal counter (not shown) is initialized (= 0) (step S1 in FIG. 3), and the wireless network # 1 is on standby (step S2 in FIG. 3). ) When the receivable information from the wireless network # 2 is received or the wireless network # 1 is out of service area (step S3 in FIG. 3), the CPU (# 1) 14 notifies the CPU (# 3) 3 to that effect. (Step S4 in FIG. 3).
[0028]
When the CPU (# 3) 3 receives the notification from the CPU (# 1) 14, the CPU (# 3) 3 confirms the vibration sensor 4 (step S5 in FIG. 3), detects vibration, or moves if the vibration amount is large. Therefore, the CPU (# 1) 14 is stopped and the switching to the CPU (# 2) 24 is started (step S9 in FIG. 3). Thereafter, the mobile phone device stands by for the wireless network # 2 (step S10 in FIG. 3).
[0029]
On the other hand, if there is no vibration or the vibration amount is small, the CPU (# 3) 3 has a high probability of being stationary, so it waits for a certain time (for example, A seconds) (the switching process itself is stopped). (Step S6 in FIG. 3), the internal counter is incremented (+1) (Step S7 in FIG. 3), and if the value of the internal counter is not equal to or greater than the predetermined value B (Step S8 in FIG. 3), the process returns to Step S2 to return to the wireless network. Wait for # 1. Here, “stationary” means that the terminal is being charged or that the object storing the terminal is in a stationary state.
[0030]
When the value of the internal counter becomes equal to or greater than the predetermined value B (step S8 in FIG. 3), the CPU (# 3) 3 stops the CPU (# 1) 14 and starts switching to the CPU (# 2) 24, as in the prior art. Is performed (step S9 in FIG. 3). Thereafter, the mobile phone device stands by for the wireless network # 2 (step S10 in FIG. 3).
[0031]
That is, if no vibration is detected by the vibration sensor 4, the own device has not moved and the base station (not shown) has not been switched, so the mobile station returns to the standby state of the wireless network # 1, and the wireless network # 2 is received, or waits for the wireless network # 1 to be out of service area.
[0032]
In addition, waiting for a certain time as described above, or checking the value of the internal counter, suppresses the increase in power consumption by repeating the same process in a short time when vibration is not detected by the vibration sensor 4, or almost detects the signal Since it is necessary to actually switch the network when the base station is switched without doing so, it is provided for retrying out.
[0033]
In this way, in this embodiment, the vibration of the own device is detected, and whether or not the mobile device is moving is added to the judgment material, so that switching of the network is positively performed so that the optimal network is obtained when the mobile device is moving. If the network is stationary, the network switching is suppressed, so that the consumption current generated when switching the network can be reduced, or the dead time when switching the network can be reduced. Can be extended and the usability can be improved.
[0034]
As a result, the network switching in the conventional switching method is performed based on information notified by radio waves or information outside the area such as electric field strength, so that in the situation where the area edge or radio wave condition is unstable, Switching of the network control unit is frequently performed, and it is possible to prevent adverse effects such as a problem of time required for switching and an increase in current consumption.
[0035]
In this embodiment, as a criterion for vibration detection, not only the presence / absence of vibration, but also the case where there was a lot of movement and a slight movement by using the vibration time as a parameter. In the case of a small amount of movement, by suppressing the aggressiveness of the network switching, it can be implemented as closer to actual use.
[0036]
【The invention's effect】
As described above, the present invention supports two or more types of wireless networks that use different communication methods, and in a mobile phone device that switches between two or more types of wireless networks and uses two or more types of wireless networks. It can be said that the use time can be extended and the usability can be improved by checking the presence or absence of the vibration with the detection means for detecting the vibration of the terminal itself and controlling the switching of the wireless network based on the detection result of the detection means. An effect is obtained.
