[0006] ここで、無線 LANのホットスポット 431 , 441は、 WCDMAネットワークの WCDMA 通信エリア 411, 421よりも遙かに狭い領域となっている。  Here, the hot spots 431 and 441 of the wireless LAN are much narrower than the WCDMA communication areas 411 and 421 of the WCDMA network.
[0007] 各基地局 410, 420は、それぞれの WCDMA通信エリア 411, 421内に存在して レ、る WCDMA通信モジュールに対して、 自局との WCDMA通信が可能な状態に W CDMA通信モジュールを起動（Wakeup)するための Wakeup信号を所定の周期で 発信している（図 2参照)。  [0007] Each base station 410, 420 has a W CDMA communication module in a state where WCDMA communication with its own station is possible with respect to the WCDMA communication module existing in the respective WCDMA communication areas 411, 421.

発明が解決しょうとする課題  Problems to be solved by the invention
[0011] しかしながら、この種の従来のデュアル端末は、 WCDMA通信による WCDMA通 信モジュールの通話中および待受中に、常時、無線 WLAN通信モジュールを起動（ WLAN Wakeup)する必要があるため消費電流が大きくなるという課題があった。  [0011] However, this type of conventional dual terminal consumes current because it is necessary to always activate the wireless WLAN communication module (WLAN Wakeup) during a call and standby of the WCDMA communication module using WCDMA communication. There was a problem of becoming larger.
[0012] 本発明者らは、このような課題を解決すべく研究を重ねた結果、この種のデュアル 端末における消費電流の増大の一因力 S、 WCDMA通信モジュールと無線 LAN通 信モジュールとの Wakeupタイミングのずれに有ることを突き止めた。  [0012] As a result of repeated research to solve such problems, the present inventors have contributed to an increase in current consumption in this type of dual terminal S, between the WCDMA communication module and the wireless LAN communication module. I found out that there was a wakeup timing shift.
[0013] すなわち、この種の従来のデュアル端末では、図 2に示すように、 WCDMA通信モ ジュールの携帯電話無線部が Wakeup信号を受信するタイミングと、無線 LAN通信 モジュールの WLAN無線部が AP検索信号を発信するタイミングとにずれがあること が半 I」つた。  [0013] That is, in this type of conventional dual terminal, as shown in FIG. 2, the timing when the mobile phone radio unit of the WCDMA communication module receives the wakeup signal and the WLAN radio unit of the wireless LAN communication module search for an AP. There was a difference in the timing of signal transmission.
[0014] これは、この種のデュアル端末における WCDMA通信モジュールと無線 LAN通 信モジュールとが、それぞれ独自のタイミングで個別に起動するように構成されてい ることによる。 [0015] このため、この種の従来のデュアル端末においては、例えば図 3に示すように、 WC DMA通信モジュールが起動（携帯電話 Wakeup)する際の電流消費に加えて、無 線 LAN通信モジュールが起動（WLAN Wakeup)する際にも同様の電流消費が 生じて端末全体の消費電流を増大させているという問題があった。 [0014] This is because the WCDMA communication module and the wireless LAN communication module in this type of dual terminal are configured to start individually at their own timing. For this reason, in this type of conventional dual terminal, as shown in FIG. 3, for example, in addition to current consumption when the WC DMA communication module is activated (mobile phone wakeup), the wireless LAN communication module When starting up (WLAN Wakeup), similar current consumption occurs, increasing the current consumption of the entire terminal.
[0016] 本発明の目的は、通信モジュールの起動時における電流消費を抑制することがで きる移動体通信端末装置を提供することである。  [0016] An object of the present invention is to provide a mobile communication terminal device that can suppress current consumption when starting up a communication module.
課題を解決するための手段  Means for solving the problem

The first communication module that performs communication by the second communication module, the second communication module that performs communication by the second communication method, and the second communication module that synchronizes with a cycle in which the first communication module is activated. And a control means for controlling a starting cycle of the second communication module so that the second communication module is started.
発明の効果  The invention's effect
[0018] 本発明によれば、前記第 1の通信モジュールの起動周期に同期して前記第 2の通 信モジュールが起動するので、前記第 1の通信モジュールの起動時の立下りに要す る時間分の消費電流と、前記第 2の通信モジュールの起動時の立上りに要する時間 分の消費電流とを節約して電流消費を抑制することができる。  According to the present invention, since the second communication module is activated in synchronization with the activation cycle of the first communication module, it is necessary for the first communication module to fall at the time of activation. Current consumption can be saved by saving the current consumption for the time and the current consumption for the time required to start up the second communication module.

[0032] そして、携帯電話無線部 111がウェイクアップ信号を受信すると、 HOST- CPU14 0は、 WCDMA通信モジュール 110を起動するように、携帯電話 Wakeup制御部 11 [0032] Then, when the mobile phone wireless unit 111 receives the wake-up signal, the HOST-CPU 140 0 starts the WCDMA communication module 110 so that the mobile phone Wakeup control unit 11
2に指示を与える。 Give instructions to 2.
[0033] また、 HOST' CPU140は、図 5に示すように、携帯電話無線部 111がウェイクアツ プ信号を受信したタイミング、つまり携帯電話 Wakeup制御部 112により WCDMA通 信モジュール 110が起動する Wakeup周期に同期して、 WLAN無線部 121が AP検 索信号を発信するように WLAN'AP検索周期制御部 122に指示を与える。  [0033] In addition, as shown in FIG. 5, the HOST 'CPU 140 receives the wake-up signal from the mobile phone radio unit 111, that is, the Wakeup cycle at which the WCDMA communication module 110 is activated by the mobile phone Wakeup control unit 112. Synchronously with this, the WLAN radio unit 121 gives an instruction to the WLAN'AP search cycle control unit 122 so as to transmit an AP search signal.
[0034] これにより、本例の移動体通信端末装置 100においては、例えば、待ち受け中に WCDMA通信モジュール 110がアンテナバー表示等のイベントを実行するために、 HOST' CPU140が Wakeupする周期に同期して、無！ ¾LANのアクセスポイントの 検索を実施することができようになる。  Thereby, in the mobile communication terminal device 100 of this example, for example, the WCDMA communication module 110 executes an event such as an antenna bar display during standby, so that the host host CPU 140 is synchronized with the wake-up cycle. No, no! ¾You can search for LAN access points.
[0035] 従って、本例の移動体通信端末装置 100においては、 WCDMA通信モジュール 1 10の起動周期に同期して、無線 LAN通信モジュール 120が起動するので、図 6に 示すように、 WCDMA通信モジュール 110の起動時の立下りに要する時間分、およ び無線 LAN通信モジュール 120の起動時の立上りに要する時間分の消費電流を節 糸勺すること力 Sできる。  Therefore, in the mobile communication terminal device 100 of the present example, the wireless LAN communication module 120 is activated in synchronization with the activation cycle of the WCDMA communication module 110, so that as shown in FIG. 6, the WCDMA communication module It is possible to save power consumption for the time required for the start-up of 110 and the time required for the start-up of the wireless LAN communication module 120.
[0036] つまり、本例の移動体通信端末装置 100においては、図 3に示した従来の携帯電 話 Wakeup時の立下がり部分の消費電流と、従来の WLAN Wakeup時の立上り部 分の消費電流とを節約することができ、通信モジュールの起動時における電流消費 を抑制することができる。  That is, in the mobile communication terminal device 100 of this example, the current consumption of the falling part during the conventional mobile phone wakeup shown in FIG. 3 and the current consumption of the rising part during the conventional WLAN wakeup are shown. And the current consumption at the time of starting the communication module can be suppressed.
[0037] ここで、本例の移動体通信端末装置 100における WLAN.AP検索周期制御部 12 2は、位置情報やセル ID、および RSSI等に応じて WLAN無線部 121の AP検索信 号の発信周期を可変するようにしてもよレ、。この場合、 WCDMA通信モジュール 11Here, the WLAN.AP search cycle control unit 122 in the mobile communication terminal device 100 of the present example performs AP search communication of the WLAN radio unit 121 according to location information, cell ID, RSSI, and the like. You can change the transmission period of the issue. In this case, WCDMA communication module 11
0の起動周期の倍数に同期して、 WLAN無線部 121の AP検索信号の発信周期を 制御することが好ましい。 It is preferable to control the transmission cycle of the AP search signal of the WLAN radio unit 121 in synchronization with a multiple of the activation cycle of 0.
[0038] つまり、 WLAN無線部 121の AP検索信号の発信周期を WCDMA通信モジユー ル 110の起動周期の倍数に同期させることにより、 AP検索信号の発信間隔が長くな るので、 AP検索信号の発信により消費される消費電流をより少なくすることができる。 That is, by synchronizing the transmission cycle of the AP search signal of the WLAN radio unit 121 with a multiple of the activation cycle of the WCDMA communication module 110, the transmission interval of the AP search signal becomes longer. Therefore, the consumption current consumed can be reduced.
[0039] また、本例の移動体通信端末装置 100においては、 WCDMA通信モジュール 11[0039] Also, in the mobile communication terminal device 100 of this example, the WCDMA communication module 11
0の起動周期に同期して、 WLAN無線部 121が無線 LANの情報を取得するように してもよい。 The WLAN radio unit 121 may acquire the wireless LAN information in synchronization with the 0 activation cycle.
