Inventive description: [Technical field of invention] The main rhyme of the present invention is a method for accelerating the automatic omnidirectional sensitivity automatic test of a mobile phone, firstly obtaining one of the channels to be tested, the final sensitivity value of the angle to be tested. The initial level power setting of the next to-be-measured angle is compared with the current reception level value of the to-be-measured angle and the reception level value of the first to-be-measured angle, and the difference is compensated to the final sensitivity value of the first-to-measurement angle In order to obtain the starting level power of the final sensitivity value closest to the current test angle. ❹ 【Prior Art】 It is necessary to conduct a Radiati〇n Test in the development of the mobile phone during the development process or the certification phase to verify whether the mobile phone meets the requirements of the relevant test specifications. The radiation test project includes the so-called 3D T〇ul Isotropic Sensitivity (TIS) test, which is the average value of the receiving sensitivity of the mobile phone in the stereo omnidirectional direction, compared to the conventional receiver. Sensitivity testing, TIS considers both the matching factor of the antenna and the receiving performance in the three-dimensional space. Therefore, it is more comprehensive to measure the receiving ability of the mobile phone, but the test of the project often takes a lot of time, the reason In terms of test specifications (eg, Hand-Machine Communication and Internet Association CTIA, Celluiar
Telecommunications & Internet Association)規定手機於進 打TIS測試時，必須進行φ轴（phi)及㊀軸^“⑻的測試，為 了構成完整之3D測試平面，手機於各軸間轉動時，必須每 間隔一固定角度（如3 0度）即經由靈敏度測試流程測得一個 平面輻射靈敏值(稱為2D EIS測試結果），最後再將每個角度 5 200934211 測得之結果經由〇:叮八測試規範定義之公式運算得到最終之 TIS數據。 另外，影響習知量測方法耗費時間長短的還有一項重 要因素，就是當不同機種的待測手機同時進行量測時，因 其内部的軟硬體不盡相同，因此將各別產生不同的靈敏度 特性，例如不同的手機使用不同的軟體、處理器、資料處 理晶片等，因而在對不同機種的手機進行總全向靈敏度量 /則時’其影響致敏度測試時間長短之最主要關鍵即在於如 ©何能快速的設定最接近待測手機的每個測量角度最終靈敏 值的起始位準功率值與如何加速求得最終測試結果的演算 法。 請參閱圖一所示係為習知手機總全向靈敏度量測方法 之步驟’首先以人工方式設定待測手機之一待測頻道之起 始位準功率11 ’此—步驟係、藉由設定量測儀器内自動測試程 式中有關靈敏度測試項目之單元功率（cell PGWer)的起始 值達成，在已開發完成之自動測試程式中，程式會於此單 ❹ 兀功率下驅動使用之量測儀器對待測手機進行靈敏度測試 U，若待測手機的靈敏值低於法規的限制值13，則將單元 功率再降低一個功率位準14(此數值是設計為可調整）並重 複上述里測，反之若待測手機的靈敏值高於法規的限制值 5則將單元功率提高—個功率位準16(此數值是設計為可 "周整）並重複上述量測，藉以求得低於法規限制值之最小單 几功率值（此即靈敏度之定義），此一步驟需一直重覆做到精 準測量出該手機目前測試頻道的靈敏度值才算完成17，繼 200934211 而將手機在同-測試頻道下旋轉至下一個待測角度ΐ8，並 繼續重覆以上所有量測的步驟，直至所有待測角度都完成 靈敏度量測之後即得-個平面韓射靈敏值數據（稱為扣抓 測試結果），最後再將每個角度測得之結果經由CTIA測試規 範定義之公式運算得到待測手機最終之犯數據19。 如上所述，因習知的詈刺古+ 旳里冽方法需逐次完成每個待測角 度的量測才能將所收集到的童f姑w ^又木幻的數據达入匚耵八測試規範内運算 〇 ，因此習知的量測方式需耗費大量的人力才能得到-完整 的總全向靈敏度數據。 採用：上ί，由於習知的總全向靈敏度測量方式係-開始 = 輸人起始量測值的方式進行測試，然後再向前或 此或減少位準功率以慢慢修正其功率位準值，因 谷產生測试人貝在主觀上判斷錯誤，且若該 並非該待測手機機種 Λ “ βΙ員 Μ Μ 研發Μ師日rnt si π ^ 測手機的特性而設定了不適當的起始功率位準值，；= 測試項目的時間更加延長，同樣的，一成本 不同待測手機機插 θ 、。人員要進行 體等構成零件不盡相同也直接影響了各別==之軟硬 ，所以上述步驟@ β μ 手機的靈敏特性 =何設計-優良的運算法則以協助準確的因 :角：最終靈敏值的起始位準功率以降低此項 高測試效率是為本發明所 之測试時 【發明内容】 肝、<課喊。 本發明之主+ 要目的在於提供—種加速手機總全向靈敏 7 200934211 度自動測試之方法，又由過去的測試經驗得知手機轉至各 1測角度後，由於手機天線受到本身機構影響，其測得之 收訊水平值(Rxlevel)會與最後得到之靈敏度測試結果；具 有-正相關的關係，因此在本發明中，除了第一個待測角 度會依據使用者設定的起純準功率經演算法求得最炊愈 敏值外，其餘待測角度均只需先量測下—個待測角度= 訊水平值，並與第一待測角度測得之收訊水平值進行比較 後’再將之間的差值補償至第—待測角度最終靈敏值以 〇取得最接近目前待測角度最終靈敏值之起始位準功率以 此方法即可有效縮短測試所需的時間。 本發明之次要目的在於提供一種加速手機總全向靈敏 度自動測試之方法，可有效縮短測試時間達25%以上。 本發明之再一目的在於提供一種加速手機總全向靈敏 度自動測試之方法，使測試系統簡單且容易使用。 —為了使貝審查委員能更進一步瞭解本發明為達成預 ❹疋目的所採取之技術、手段及功效，請參閱以下有關本發 Z之詳細說明與附圖，相信本發明之目的、特徵與特點， 田可由此得一冰入且具體之瞭解，然而所附圖式僅提供參 考與說明用，並非用來對本發明加以限制者。 【實施方式】 晴參閱圖二係為本發明加速手機總全向靈敏度自動測 試之方法之實施步驟： 步驟（50)以手動方式設定—待測頻道之起始位準功率， 並以目前待測角度做為第一待測角度。 8 200934211 步驟(51)量測目前待測角度之位元誤差率(叫 步驟(52)由位元誤差率判断在目前位準功率下，待測角 度之靈敏值是否為最低靈齡 》 - 敏值右疋，則以此最低靈 敏值做為目前待測角度之昜炊 β <敢終靈敏值；至步驟（30)。 步驟（20)若量測到之位元 >差率小於等於0.1%(BER $ 0.1 /))，則將目前之功率位進咏把z & 刀平位準降低4個位準功率值；至 步驟（51)。 步驟（2 1)若量測到之位元誤罢Telecommunications & Internet Association) stipulates that the mobile phone must perform the φ axis (phi) and one axis ^ (8) test when entering the TIS test. In order to form a complete 3D test plane, the mobile phone must rotate every axis. A fixed angle (such as 30 degrees) is a plane radiation sensitivity value (called 2D EIS test result) measured through the sensitivity test process, and finally the result measured by each angle 5 200934211 is defined by 〇: 测试8 test specification The formula is calculated to obtain the final TIS data. In addition, an important factor affecting the length of the conventional measurement method is that when the mobile phones of different models are simultaneously measured, the internal software and hardware are inexhaustible. The same, so different sensitivity characteristics will be generated separately, for example, different mobile phones use different software, processors, data processing chips, etc., so the total omnidirectional sensitivity/time is sensitized to different mobile phones of different models. The main key to the length of the test is how to quickly set the closest measurement angle to the mobile phone to be tested. The starting level value of the sensitive value and the algorithm for how to accelerate the final test result. Please refer to the steps shown in Figure 1 for the conventional omnidirectional sensitivity measurement method of the mobile phone. First, manually set the mobile phone to be tested. The starting level power of one of the channels to be tested is 11'. This step is achieved by setting the starting value of the unit power (cell PGWer) of the sensitivity test item in the automatic test program in the measuring instrument. In the automatic test program, the program will perform the sensitivity test U on the measuring device to be used for driving the measuring instrument under the power consumption of the unit. If the sensitivity value of the mobile phone to be tested is lower than the regulatory limit value 13, the unit power is lowered. A power level 14 (this value is designed to be adjustable) and repeat the above test, if the sensitivity of the phone to be tested is higher than the limit value of the regulation 5, the unit power is increased - a power level of 16 (this value is Designed to "can be" and repeat the above measurement, in order to obtain the minimum single power value below the regulatory limit (this is the definition of sensitivity), this step must be repeated Accurately measure the sensitivity value of the current test channel of the mobile phone to complete 17 , and then rotate the mobile phone under the same-test channel to the next test angle ΐ 8 according to 200934211, and continue to repeat all the above measurement steps until all the waiting After the measurement angle is completed, the sensitivity measurement is obtained - a flat Korean sensitivity data (called the result of the buckle test), and finally the result of each angle is calculated by the formula defined by the CTIA test specification to obtain the final mobile phone to be tested.

The main purpose of the present invention is to provide a method for accelerating the automatic omnidirectional sensitivity of the mobile phone 7 200934211 degree, and from the past test experience, the mobile phone is transferred to each 1 Angle measurement After that, since the mobile phone antenna is affected by its own mechanism, the measured reception level value (Rxlevel) will be related to the final sensitivity test result; there is a positive correlation, so in the present invention, except for the first to-be-tested angle According to the purely quasi-power set by the user, the final sensibility value is obtained by the algorithm. The other angles to be measured only need to be measured first - the angle to be tested = the level of the signal, and the angle to be measured After the measured level of the received signal is compared, the difference between the measured value and the final sensitive value of the angle to be measured is obtained to obtain the initial level of the closest sensitive value of the current angle to be tested. The secondary object of the present invention is to provide a method for accelerating the automatic omnidirectional sensitivity automatic test of the mobile phone, which can effectively shorten the test time by more than 25%. Another object of the present invention is to provide an accelerated mobile phone. The method of automatic testing of total omnidirectional sensitivity makes the test system simple and easy to use. - In order to enable the Beck Review Committee to further understand the present invention for the purpose of achieving For the technology, means and functions, please refer to the following detailed description and drawings of the present invention.

Whether the sfL level value (Rxl) at the final sensitivity value (si) of the first to-be-measured angle has been obtained in step (30), and if so, to step (32). Step (3 1) takes the value of the reception level (Rx 1) at the final sensitivity value (s 1) of the first angle to be measured. Step (32) whether all the measured angles of the channel to be tested are completed, if yes to step (40). 200934211 Step (33) rotates to the next _ to be measured angle under the same channel to be tested. Step (34) obtains the reception level value (Rxn) of the current angle to be tested. Step (35) is substituted into the calculation formula to obtain the starting level power of the final sensitive value of the current to-be-measured angle as the starting level power value of the current to-be-measured angle (Cell Power; CP); to step (11) . The calculation formula of this step is as follows: CPn==Sl-(Rxii- Rxl) For example, the final sensitivity value (sl) of the first to-be-measured angle is n〇2dBm, and the reception level value (RX1) is 20'. The angle of reception (Rxn) of the angle is 22 (due to the influence of factors such as the mobile phone mechanism, different angles will be generated at different angles) 'The next level of reception level (RXn) and the first The receiving level value of the angle to be measured (4) is reduced by 〇(4)2(22·2ϋ=2), and this value is used as the compensation value of the final sensitive value of the first-to-measure angle, 舆篦—4 main & The final sensitivity value of the angle measurement (S1) is calculated, and the value of the starting level of the τ-amount to be measured is -10, m () 〇 2dBm~ Bm), and the power value is The minimum sensitivity value of a to-be-measured angle is the starting level power of the current measured angle closest to the lowest sensitivity value, and only a slight adjustment is required to obtain the minimum sensitivity value, and thus the maximum sensitivity value can be greatly reduced. (iv) The time required for the test. V (〇) calculates the results of all angles through the test specification definition 200934211 to obtain the final TIS data. It can be seen from the above that the present invention can effectively reduce the conventional amount by using an empirical algorithm to quickly obtain the final sensitivity value of each angle to be measured and the initial level power value closest to the minimum sensitivity value of the angle to be measured. Time is measured to quickly obtain the total omnidirectional sensitivity of the mobile phone under test. The method for accelerating the automatic omnidirectional sensitivity automatic test of the mobile phone has the following advantages: / (1) The final sensitivity value and the reception level value of the first test angle of the channel to be tested of the mobile phone can be used as other angles to be measured.
