Description
本案是有關於一種降低切換通訊通道次數的方法及其行動裝置。 This case is about a method for reducing the number of switching communication channels and its mobile device.
無線通訊設備的通訊品質會因自身干擾(self-jamming)、外在干擾(interference)、當下通道(channel)狀態(例如路徑損失(path loss)、遮蔽(shadowing)、多重路徑(multipath)、衰減(fading))及天線輻射場形等因素而出現大幅度的變動，造成基地台需即時對無線通訊設備作出不同程度的功率調整或通道切換控制，以維持正常的服務品質(Quality of Service，QoS)。 The communication quality of wireless communication devices may be self-jamming, external interference, current channel state (such as path loss, shadowing, multipath, attenuation). (fading) and antenna radiation field shape and other factors have undergone significant changes, causing the base station to immediately make different levels of power adjustment or channel switching control for wireless communication equipment to maintain normal quality of service (Quality of Service, QoS) ).
當基地台發現無線通訊設備的傳輸功率過低時，基地台將會判斷無線通訊設備的訊號品質過差，因而可能對無線通訊設備發出切換通訊通道(即，交遞(handover))的要求。然而，由 於無線通訊設備在執行交遞的操作時將大幅提升傳輸功率，因此，無線通訊設備因應於基地台的要求所進行的非必要交遞操作將無謂地增加無線通訊設備的功耗。 When the base station finds that the transmission power of the wireless communication device is too low, the base station will judge that the signal quality of the wireless communication device is too poor, and thus may issue a communication channel (ie, handover) request to the wireless communication device. However, by When the wireless communication device performs the handover operation, the transmission power will be greatly improved. Therefore, the unnecessary communication operation performed by the wireless communication device according to the requirements of the base station will unnecessarily increase the power consumption of the wireless communication device.
有鑑於此，本案提供降低切換通訊通道次數的方法及其行動裝置，其可藉由提升行動裝置的最低允許傳送功率的方式來降低執行交遞操作的次數。 In view of this, the present invention provides a method for reducing the number of times of switching communication channels and a mobile device thereof, which can reduce the number of times of performing a handover operation by increasing the minimum allowed transmission power of the mobile device.
本案提供一種降低切換通訊通道次數的方法，適於行動裝置。所述方法包括下列步驟：依據行動裝置在預設時間區間內的多個位置資訊判斷行動裝置是否為靜止狀態或半靜止狀態；當行動裝置為靜止狀態或半靜止狀態時，識別行動裝置所在的區域以及通訊模式；依據行動裝置在通訊模式下使用的多個傳送功率建立傳送功率變化表，其中傳送功率變化表對應於區域及通訊模式，且傳送功率變化表記錄行動裝置使用所述多個傳送功率的次數；從傳送功率變化表中尋找具有最高使用次數的特定傳送功率；將行動裝置的最低允許傳送功率提升為高於特定傳送功率的目標傳送功率；以及記錄目標傳送功率。 The present invention provides a method for reducing the number of times of switching communication channels, which is suitable for mobile devices. The method includes the steps of: determining whether the mobile device is in a stationary state or a semi-stationary state according to the plurality of location information of the mobile device in the preset time interval; and identifying the mobile device when the mobile device is in a stationary state or a semi-stationary state a region and a communication mode; establishing a transmission power change table according to the plurality of transmission powers used by the mobile device in the communication mode, wherein the transmission power change table corresponds to the area and the communication mode, and the transmission power change table records the mobile device using the plurality of transmissions The number of times of power; the specific transmission power having the highest number of uses is found from the transmission power change table; the lowest allowed transmission power of the mobile device is raised to a target transmission power higher than the specific transmission power; and the target transmission power is recorded.
本案提供一種行動裝置，包括收發器、儲存單元以及處理單元。儲存單元儲存多個模組。處理單元連接收發器以及儲存單元，存取並執行所述多個模組。所述多個模組包括判斷模組、識別模組、建立模組、尋找模組、提升模組以及記錄模組。判斷 模組依據行動裝置在預設時間區間內的多個位置資訊判斷行動裝置是否為靜止狀態或半靜止狀態。當行動裝置為靜止狀態或半靜止狀態時，識別模組識別行動裝置所在的區域以及通訊模式。建立模組依據行動裝置在通訊模式下使用的多個傳送功率建立傳送功率變化表。傳送功率變化表對應於區域及通訊模式。傳送功率變化表記錄行動裝置使用所述多個傳送功率的次數。尋找模組從傳送功率變化表中尋找具有最高使用次數的特定傳送功率。提升模組將行動裝置的最低允許傳送功率提升為高於特定傳送功率的目標傳送功率。記錄模組記錄目標傳送功率。 The present invention provides a mobile device including a transceiver, a storage unit, and a processing unit. The storage unit stores a plurality of modules. The processing unit is coupled to the transceiver and the storage unit to access and execute the plurality of modules. The plurality of modules include a determination module, an identification module, an establishment module, a search module, a lifting module, and a recording module. Judge The module determines whether the mobile device is in a stationary state or a semi-stationary state according to the plurality of location information of the mobile device in the preset time interval. When the mobile device is in a stationary state or a semi-stationary state, the recognition module identifies the area in which the mobile device is located and the communication mode. The setup module establishes a transmit power change table based on the plurality of transmit powers used by the mobile device in the communication mode. The transmission power change table corresponds to the area and communication mode. The transmission power change table records the number of times the mobile device uses the plurality of transmission powers. The search module looks for a specific transmit power with the highest number of uses from the transmit power change table. The boost module boosts the minimum allowable transmit power of the mobile device to a target transmit power that is higher than the specific transmit power. The recording module records the target transmission power.
基於上述，在將最低允許傳送功率提升為目標傳送功率之後，由於行動裝置不會再使用過低的傳送功率，因此基地台不會過於頻繁地要求行動裝置執行交遞操作。如此一來，行動裝置進行交遞操作的次數即可降低，進而降低行動裝置的功耗。 Based on the above, after the minimum allowed transmission power is boosted to the target transmission power, since the mobile device does not use the transmission power too low, the base station does not require the mobile device to perform the handover operation too frequently. In this way, the number of times the mobile device performs the handover operation can be reduced, thereby reducing the power consumption of the mobile device.

圖2是依據本案之一實施例繪示的降低切換通訊通道次數方法流程圖。本實施例的方法可由圖1的行動裝置100執行，以下即搭配圖1中的各個元件來說明本方法各個步驟的細節。 2 is a flow chart of a method for reducing the number of times of switching communication channels according to an embodiment of the present invention. The method of this embodiment can be performed by the mobile device 100 of FIG. 1, and the details of the various steps of the method will be described below in conjunction with the various elements in FIG.
在步驟S210中，判斷模組120_1可依據行動裝置100在預設時間區間內的多個位置資訊判斷行動裝置100是否為靜止狀態或半靜止狀態。 In step S210, the determining module 120_1 can determine whether the mobile device 100 is in a stationary state or a semi-stationary state according to the plurality of location information of the mobile device 100 in the preset time interval.
在一實施例中，所述預設時間區間例如是數個微秒至數秒的時間區間，而判斷模組120_1可透過例如輔助全球定位系統A-GPS(assisted global positioning system，A-GPS)、GPS、媒體存取控制(media access control，MAC)位址以及基地台細胞識別 碼(cell identification，cell ID)等系統或資料來取得行動裝置100的座標等位置資訊。接著，判斷模組120_1即可基於行動裝置100的座標在所述預設時間區間中的改變情形來計算行動裝置100的移動速度，進而依據此移動速度來判斷行動裝置100是否為靜止狀態或半靜止狀態。 In an embodiment, the preset time interval is, for example, a time interval of several microseconds to several seconds, and the determining module 120_1 can pass, for example, an assisted global positioning system (A-GPS), GPS, media access control (MAC) address and base station cell identification A system or data such as a cell identification (cell ID) is used to obtain position information such as coordinates of the mobile device 100. Then, the determining module 120_1 can calculate the moving speed of the mobile device 100 based on the change of the coordinates of the mobile device 100 in the preset time interval, and further determine whether the mobile device 100 is in a stationary state or a half according to the moving speed. Stationary state.
應了解的是，靜止狀態及半靜止狀態的定義可因應於行動裝置100所使用的通訊標準而有所不同。舉例而言，假設行動裝置100使用的是屬於第三代合夥專案(Third Generation Partnership Project，3GPP)下的高速下載封包存取(High Speed Download Packet Access，HSDPA)協定，則判斷模組120_1可據以判定行動裝置100為靜止狀態、半靜止狀態或是移動(mobility)狀態。所述靜止狀態例如是行動裝置100靜止不動的狀態，所述半靜止狀態例如是行動裝置100正以較為緩慢的速度(例如人類的步行速度)在移動的狀態，而所述移動狀態例如是行動裝置100正以較快的速度在移動的狀態(例如車輛移動的速度)，但本案的可實施方式不限於此。 It should be understood that the definition of the quiescent state and the semi-stationary state may vary depending on the communication standard used by the mobile device 100. For example, if the mobile device 100 uses the High Speed Download Packet Access (HSDPA) protocol under the Third Generation Partnership Project (3GPP), the determination module 120_1 can It is determined that the mobile device 100 is in a stationary state, a semi-stationary state, or a mobility state. The stationary state is, for example, a state in which the mobile device 100 is stationary, such as a state in which the mobile device 100 is moving at a relatively slow speed (for example, a walking speed of a human being), and the moving state is, for example, an action. The device 100 is in a moving state (e.g., the speed at which the vehicle moves) at a relatively fast speed, but the embodiments of the present invention are not limited thereto.
當行動裝置100不為靜止狀態或半靜止狀態時，在步驟S270中，處理單元130可依據所使用的通訊標準進行資料傳輸。 When the mobile device 100 is not in a stationary state or a semi-stationary state, in step S270, the processing unit 130 may perform data transmission according to the communication standard used.
另一方面，當行動裝置100為靜止狀態或半靜止狀態時，在步驟S220中，識別模組120_2可識別行動裝置100所在的區域以及通訊模式。在一實施例中，識別模組120_2可依據行動裝置100的座標來識別其所在的區域。所述區域例如是住家、公司或辦 公室等場所。所述通訊模式例如是行動裝置100當下所使用的通訊標準中所定義的資料傳輸模式、語音通話模式或待機(idle)模式等。所述通訊標準例如是第二代、第三代或***行動通訊系統等，但不限於此。 On the other hand, when the mobile device 100 is in a stationary state or a semi-stationary state, in step S220, the recognition module 120_2 can identify the region in which the mobile device 100 is located and the communication mode. In an embodiment, the recognition module 120_2 can identify the area in which the mobile device 100 is located according to the coordinates of the mobile device 100. The area is for example a home, company or office Places such as the office. The communication mode is, for example, a data transmission mode, a voice call mode, or an idle mode defined in a communication standard currently used by the mobile device 100. The communication standard is, for example, a second generation, a third generation or a fourth generation mobile communication system, etc., but is not limited thereto.
在步驟S230中，建立模組120_3可依據行動裝置100在所述通訊模式下使用的多個傳送功率建立傳送功率變化表。在一實施例中，建立模組120_3可取得所述通訊標準所定義的多個傳送功率準位(transmission power level，以下簡稱TXLEV)，並初始化對應於這些傳送功率準位的計數值(例如是0)。接著，當行動裝置100使用所述多個傳送功率中的第一傳送功率時，建立模組120_3可從所述多個傳送功率準位中尋找對應於第一傳送功率的第一傳送功率準位，並累加對應於第一傳送功率準位TXLEV的計數值(其代表行動裝置100使用第一傳送功率的次數)。值得說明的是，功率準位係以一功率值範圍之中間值標示。 In step S230, the setup module 120_3 may establish a transmission power change table according to the plurality of transmission powers used by the mobile device 100 in the communication mode. In an embodiment, the establishing module 120_3 can obtain a plurality of transmission power levels (TXLEVs) defined by the communication standard, and initialize a count value corresponding to the transmission power levels (for example, 0). Then, when the mobile device 100 uses the first transmit power of the multiple transmit powers, the setup module 120_3 may search for the first transmit power level corresponding to the first transmit power from the multiple transmit power levels. And accumulating a count value corresponding to the first transmit power level TXLEV (which represents the number of times the mobile device 100 uses the first transmit power). It is worth noting that the power level is indicated by the middle value of a range of power values.
表1例如是當所述通訊標準為第二代行動通訊系統時，建立模組120_3依據行動裝置100在所述通訊模式下使用的多個傳送功率所建立的傳送功率變化表。以第二代行動通訊系統的高頻段(DCS1800/PCS1900)為例子，其規範了16種傳送功率準位(即，TXLEV 0~TXLEV 15)，故建立模組120_3可建立對應於這16種傳送功率準位的欄位，並將這些傳送功率準位各別的計數值初始化為0。接著，當行動裝置100使用對應於某個傳送功率準位的第一傳送功率時，建立模組120_1可對應地累加此傳送功率準位的計數值，也就是行動裝置100使用第一傳送功率的次數。因 此，從表1中可看出行動裝置100使用對應於各個傳送功率準位的傳送功率的次數。舉例而言，行動裝置100使用對應於TXLEV 0的傳送功率的次數為367次，而行動裝置100使用對應於TXLEV 1的傳送功率的次數為747次。 Table 1 is, for example, a transmission power change table established by the setup module 120_3 according to a plurality of transmission powers used by the mobile device 100 in the communication mode when the communication standard is a second generation mobile communication system. Taking the high frequency band (DCS1800/PCS1900) of the second generation mobile communication system as an example, which specifies 16 transmission power levels (ie, TXLEV 0~TXLEV 15), the setup module 120_3 can establish corresponding to the 16 transmissions. The field of the power level and initializes the respective count values of these transmission power levels to zero. Then, when the mobile device 100 uses the first transmit power corresponding to a certain transmit power level, the setup module 120_1 can correspondingly accumulate the count value of the transmit power level, that is, the mobile device 100 uses the first transmit power. frequency. because Thus, it can be seen from Table 1 that the mobile device 100 uses the number of transmission powers corresponding to the respective transmission power levels. For example, the number of times the mobile device 100 uses the transmission power corresponding to TXLEV 0 is 367 times, and the number of times the mobile device 100 uses the transmission power corresponding to TXLEV 1 is 747 times.
應了解的是，由於第二代行動通訊系統是以位階(step)的形式傳送功率，故表1中稱為傳送功率準位，每一傳送功率準位包括一功率範圍，每一功率範圍依據3GPP規範為2dB，並以功率範圍之中間值表示，傳送功率準位越高代表的是越低的傳送功率，反之亦然。亦即，TXLEV 0對應的傳送功率最高，而TXLEV 15對應的傳送功率則最低。在其他實施例中，依據第三代行動通訊系統之傳送功率為連續，每一間隔為1dB，故傳送功率變化表可直接以單一傳送功率值對應一次數計算，本案不以此為限。 It should be understood that since the second generation mobile communication system transmits power in the form of a step, it is referred to as a transmission power level in Table 1, and each transmission power level includes a power range, and each power range is based on The 3GPP specification is 2 dB and is expressed in the middle of the power range. The higher the transmission power level, the lower the transmission power and vice versa. That is, TXLEV 0 corresponds to the highest transmission power, while TXLEV 15 corresponds to the lowest transmission power. In other embodiments, the transmission power of the third generation mobile communication system is continuous, and each interval is 1 dB. Therefore, the transmission power change table can be directly calculated by a single transmission power value for a number of times, which is not limited thereto.
從表1中可清楚看出，TXLEV 10及TXLEV 11的計數值明顯高於其他的傳送功率準位。也就是說，表1所反映出的現象是行動裝置100較為頻繁地使用較低的傳送功率，因而可能導致行動裝置100頻繁地被基地台要求切換通訊通道(即，交遞)。在此情況下，將可能導致行動裝置100的功耗因為執行過多交遞操作而大幅提升。然而，在執行圖2實施例中的步驟S240~S260之後，即可有效地降低行動裝置100進行交遞操作的次數，進而降低行動裝置100的功耗。具體說明如下。 As is clear from Table 1, the count values of TXLEV 10 and TXLEV 11 are significantly higher than other transmission power levels. That is, the phenomenon reflected in Table 1 is that the mobile device 100 uses the lower transmission power more frequently, and thus may cause the mobile device 100 to be frequently requested by the base station to switch the communication channel (ie, handover). In this case, it is likely that the power consumption of the mobile device 100 is greatly increased due to the execution of too many handover operations. However, after performing steps S240 to S260 in the embodiment of FIG. 2, the number of times the mobile device 100 performs the handover operation can be effectively reduced, thereby reducing the power consumption of the mobile device 100. The details are as follows.
在步驟S240中，尋找模組120_4可從傳送功率變化表中尋找具有最高使用次數的傳送功率準位，並定義其為一特定傳送 功率。以表1為例，其中具有最高使用次數的傳送功率準位為對應於TXLEV 10的傳送功率。 In step S240, the search module 120_4 can find the transmission power level with the highest usage count from the transmission power change table, and define it as a specific transmission. power. Taking Table 1 as an example, the transmission power level having the highest usage count is the transmission power corresponding to TXLEV 10.
接著，在步驟S250中，提升模組120_5可將行動裝置100的最低允許傳送功率提升為高於特定傳送功率的一目標傳送功率。並且，在步驟S260中，記錄模組120_6可記錄目標傳送功率。所述最低允許傳送功率代表行動裝置100的傳送功率的下限值，亦即行動裝置100不會以低於所述最低允許傳送功率的功率來進行傳送。 Next, in step S250, the lifting module 120_5 can boost the minimum allowed transmission power of the mobile device 100 to a target transmission power higher than the specific transmission power. And, in step S260, the recording module 120_6 can record the target transmission power. The minimum allowable transmission power represents a lower limit value of the transmission power of the mobile device 100, that is, the mobile device 100 does not transmit at a power lower than the minimum allowed transmission power.
以表1為例，提升模組120_5可先尋找對應於所述特定傳送功率的特定傳送功率準位(也就是TXLEV 10)。接著，提升模組120_5可設定高於TXLEV 10的某一傳送功率作為目標傳送功率，並依據目標傳送功率設定目標傳送功率。 Taking Table 1 as an example, the boost module 120_5 may first find a specific transmit power level (ie, TXLEV 10) corresponding to the specific transmit power. Then, the lifting module 120_5 can set a certain transmission power higher than the TXLEV 10 as the target transmission power, and set the target transmission power according to the target transmission power.
舉例而言，假設提升模組120_5選取比TXLEV 10高一個準位的TXLEV 9作為目標傳送功率，則提升模組120_5可設定所述最低允許傳送功率為對應於TXLEV 9的傳送功率。舉另一例而言，假設提升模組120_5選取比TXLEV 10高兩個準位的TXLEV 8作為目標傳送功率，則提升模組120_5可設定所述最低允許傳送功率為對應於TXLEV 8的傳送功率。本領域具通常知識者應可了解，上述預設數量準位僅用以舉例，並非用以限定本案的可實施方式。 For example, if the boost module 120_5 selects the TXLEV 9 that is one level higher than the TXLEV 10 as the target transmit power, the boost module 120_5 can set the minimum allowable transmit power to be the transmit power corresponding to the TXLEV 9. For another example, if the boost module 120_5 selects the TXLEV 8 that is two levels higher than the TXLEV 10 as the target transmit power, the boost module 120_5 can set the minimum allowable transmit power to be the transmit power corresponding to the TXLEV 8. It should be understood by those of ordinary skill in the art that the above-mentioned preset number of levels are merely exemplary and are not intended to limit the implementation of the present invention.
在提升模組120_5將最低允許傳送功率提升為目標傳送功率之後，由於行動裝置100不會再使用過低的傳送功率，因此 基地台不會過於頻繁地要求行動裝置100執行交遞操作。如此一來，行動裝置100進行交遞操作的次數即可降低，進而降低行動裝置100的功耗。 After the lifting module 120_5 boosts the minimum allowed transmission power to the target transmission power, since the mobile device 100 no longer uses the low transmission power, The base station does not require the mobile device 100 to perform the handover operation too frequently. As a result, the number of times the mobile device 100 performs the handover operation can be reduced, thereby reducing the power consumption of the mobile device 100.
在一實施例中，儲存單元120可更包括功率調整模組120_7，用以在行動裝置100再次在前述區域中使用前述通訊模式時，控制行動裝置100以前述目標傳送功率為當下最低允許傳送功率進行傳輸。如此一來，當行動裝置100往後在所述區域中使用所述通訊標準及通訊模式進行傳輸時，行動裝置100的功耗將可對應地減少。 In an embodiment, the storage unit 120 may further include a power adjustment module 120_7 for controlling the mobile device 100 to use the foregoing target transmission power as the current minimum allowed transmission power when the mobile device 100 uses the foregoing communication mode again in the foregoing area. Transfer. In this way, when the mobile device 100 transmits the communication standard and the communication mode in the area in the future, the power consumption of the mobile device 100 can be correspondingly reduced.
為了證明本案的方法所能達到的效果，以下提供一實施例來進行說明。 In order to demonstrate the effects that can be achieved by the method of the present invention, an embodiment will be provided below for explanation.
表2例如是行動裝置100採用對應於TXLEV 8的傳送功率作為最低允許傳送功率所建立的傳送功率變化表，其所採用的環境實質上相同於建立表1時所使用的環境(即，相同的區域、通訊標準及通訊模式)。 Table 2 is, for example, a transmission power change table established by the mobile device 100 using the transmission power corresponding to the TXLEV 8 as the lowest allowed transmission power, and the environment employed is substantially the same as the environment used when the table 1 is established (ie, the same Regional, communication standards and communication modes).
從表2可清楚看出，TXLEV 10及11的計數值(皆為0)明顯低於表1中TXLEV 10及11的計數值(即，2209及1368)。也就是說，在行動裝置100採用對應於TXLEV 8的傳送功率作為最低允許傳送功率之後，行動裝置100的傳送功率降低至TXLEV 10或11的可能性已幾乎完全地消除。換言之，表2所反映出的交遞次數將明顯低於表1所反映出的交遞次數，因而能夠達到較低的功耗。為了讓表1及表2所呈現的趨勢變化更為清楚，以下另輔以圖3進行說明。 As is clear from Table 2, the count values of TXLEV 10 and 11 (all 0) are significantly lower than the count values of TXLEV 10 and 11 in Table 1 (i.e., 2209 and 1368). That is, after the mobile device 100 adopts the transmission power corresponding to the TXLEV 8 as the minimum allowable transmission power, the possibility that the transmission power of the mobile device 100 is lowered to the TXLEV 10 or 11 has been almost completely eliminated. In other words, the number of handovers reflected in Table 2 will be significantly lower than the number of handovers reflected in Table 1, thus achieving lower power consumption. In order to make the trend changes shown in Tables 1 and 2 clearer, the following description will be supplemented with FIG.
圖3是依據表1及表2所繪示的趨勢圖。在本實施例中， 橫軸代表TXLEV，縱軸為計數值。曲線310及320分別為依據表1及表2所繪示的趨勢圖。從圖3中可清楚看出，曲線320的趨勢相較於曲線310明顯地偏左。也就是說，曲線320所反映出的交遞次數遠低於曲線310所反映出的交遞次數。 FIG. 3 is a trend diagram according to Table 1 and Table 2. In this embodiment, The horizontal axis represents TXLEV and the vertical axis represents the count value. Curves 310 and 320 are trend diagrams according to Tables 1 and 2, respectively. As is clear from Figure 3, the trend of curve 320 is significantly skewed to the left compared to curve 310. That is to say, the number of handovers reflected by the curve 320 is much lower than the number of handovers reflected by the curve 310.
在其他實施例中，由於所述區域中的環境有可能隨著時間而變動(例如出現新增的基地台或者是舊基地台被汰換掉)，因此當行動裝置100已使用目標傳送功率一段預設時間(例如數週或數月)時，判斷模組120_1、識別模組120_2、建立模組120_3、尋找模組120_4、提升模組120_5以及記錄模組120_6可再次執行步驟S210~S260以取得新的目標傳送功率。 In other embodiments, since the environment in the area is likely to change over time (eg, a new base station or an old base station is replaced), the mobile device 100 has used the target transmit power for a period of time. When the preset time (for example, several weeks or months), the determining module 120_1, the identifying module 120_2, the establishing module 120_3, the searching module 120_4, the lifting module 120_5, and the recording module 120_6 may perform steps S210-S260 again. Get new target transmit power.
綜上所述，在透過本案實施例提出的方法將行動裝置的最低允許傳送功率提升為目標傳送功率之後，由於行動裝置不會再使用過低的傳送功率，因此基地台不會過於頻繁地要求行動裝置執行交遞操作。如此一來，行動裝置進行交遞操作的次數即可降低，進而降低行動裝置的功耗。 In summary, after the minimum allowed transmission power of the mobile device is raised to the target transmission power by the method proposed in the embodiment of the present invention, since the mobile device does not use the transmission power too low, the base station does not request the frequency too frequently. The mobile device performs the handover operation. In this way, the number of times the mobile device performs the handover operation can be reduced, thereby reducing the power consumption of the mobile device.
並且，只要先前行動裝置已基於本案提出的方法找出對應於某區域、某通訊標準及某通訊模式的目標傳送功率之後，行動裝置往後即可直接沿用此目標傳送功率作為最低允許傳送功率來進行傳輸，無需再重新執行一次本案的方法。 Moreover, as long as the previous mobile device has found the target transmission power corresponding to a certain area, a communication standard, and a certain communication mode based on the method proposed in the present case, the mobile device can directly use the target transmission power as the minimum allowable transmission power. For transmission, there is no need to re-execute the method of this case.
雖然本案已以實施例揭露如上，然其並非用以限定本案，任何所屬技術領域中具有通常知識者，在不脫離本案的精神和範圍內，當可作些許的更動與潤飾，故本案的保護範圍當視後 附的申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present case. Any person having ordinary knowledge in the technical field can protect the case without making any changes or refinements without departing from the spirit and scope of the present case. Scope after viewing The scope defined in the attached patent application shall prevail.
