Description

移动无线终端中成功通信概率显示装置及其有关方法Apparatus for displaying probability of successful communication in mobile wireless terminal and related method

本发明涉及移动无线电终端，更具体地说，涉及一种成功通信概率显示装置，供显示象CDMA(码分多址)移动无线电电话机之类的移动无线电终端获得成功通信的概率。The present invention relates to mobile radio terminals, and more particularly, to a successful communication probability display device for displaying the probability of successful communication obtained by a mobile radio terminal such as a CDMA (Code Division Multiple Access) mobile radio telephone.

通常，移动无线电终端通过不断检测收自基地台信号的所收到信号强度标志(RSSI)显示达到成功通信的概率。举例说，这类概率在移动无线电终端的LCD(液晶显示器)上以三种条形框图显示出来，如图1至3中所示。若检测出的RSSI强，表明成功通信的概率最高，则分别为小、中、大的所有三个框条就顺次显示出来，如图3中所示。同样，若检测出的RSSI分别为中等或微弱，则分别表明概率较小或最小，就如图2中所示那样显示出小框条和中等框条，或如图1中所示那样只显示出小框条。Typically, mobile radio terminals indicate the probability of successful communication by continuously monitoring the Received Signal Strength Indicator (RSSI) of the signal received from the base station. Such probabilities are displayed as three bar graphs on the LCD (Liquid Crystal Display) of the mobile radio terminal, as shown in FIGS. 1 to 3, for example. If the detected RSSI is strong, it indicates that the probability of successful communication is the highest, and then all three frames of small, medium, and large are displayed sequentially, as shown in FIG. 3 . Similarly, if the detected RSSI is medium or weak, respectively, it indicates that the probability is small or minimal, as shown in Figure 2, the small frame and medium frame are displayed, or as shown in Figure 1, only the Out of the small frame.

然而，达到顺利通信的概率并不只与RSSI有关。若有来自毗邻信道或基地台的无线电波干扰，则RSSI再强，概率也还是会下降的。因此，有人建议，显示概率时考虑到所收到信号的数据误差率。例如，若检测出RSSI强但误差率高，则显示出低的概率。但这样就不能正确告诉用户造成达到顺利通信概率的原因。However, the probability of achieving smooth communication is not only related to RSSI. If there is radio wave interference from adjacent channels or base stations, no matter how strong the RSSI is, the probability will still decrease. It has therefore been suggested that the probability display takes into account the data error rate of the received signal. For example, if it detects that the RSSI is strong but the error rate is high, then a low probability is shown. However, this cannot correctly inform the user of the cause of the probability of achieving smooth communication.

本发明的目的是提供一种能正确告诉用户造成达到顺利通信概率的原因的移动无线电终端顺利通信概率显示装置。SUMMARY OF THE INVENTION It is an object of the present invention to provide a smooth communication probability display device for a mobile radio terminal which can correctly inform the user of the cause of attainment of the smooth communication probability.

按照本发明的一个方面，本发明显示移动无线电电话机达到顺利通信概率的方法包括下列步骤：检测所收到信号的RSSI；检测所收到信号的数据误差率从而产生所收到信号的干扰电平；显示有关RSSI和所收到信号干扰电平的信息。According to one aspect of the present invention, the method of the present invention for displaying the probability of a successful communication by a mobile radiotelephone includes the steps of: detecting the RSSI of the received signal; detecting the data error rate of the received signal to generate an interference level of the received signal Flat; displays information about the RSSI and interference level of the received signal.

现在参看仅为举例说明的附图更具体地说明本发明。The invention will now be more particularly described with reference to the accompanying drawings, which are shown by way of illustration only.

图1至图3是现有技术在一般的移动无线电终端的LCD上显示出的框条的示意图，这些框条表示达到顺利通信的概率。1 to 3 are prior art diagrams of bars displayed on an LCD of a general mobile radio terminal, which indicate the probability of achieving smooth communication.

图4是本发明移动无线电电话机的方框图。Figure 4 is a block diagram of the mobile radiotelephone of the present invention.

图5是本发明移动无线电电话机的LCD上显示出的框条的示意图。Fig. 5 is a schematic diagram of a frame bar displayed on an LCD of the mobile radiotelephone of the present invention.

图6是本发明显示移动无线电电话机获得成功通信概率的过程流程图。Figure 6 is a flow diagram of the process of the present invention showing the probability of successful communication achieved by the mobile radiotelephone.

本发明给移动无线电电话机配备一种通过分别显示所收到信号的RSSI和干扰电平，使用户可以正确知道造成获得成功通信概率的原因的装置。The present invention equips a mobile radiotelephone with a means by which the user can correctly know the cause of the probability of obtaining successful communication by separately displaying the RSSI and the interference level of the received signal.

参看图4，移动无线电电话机的整个功能由微处理器100控制。微处理器100还在显示器106上显示收自信号电平检测器110的信号的RSSI和收自干扰电平检测器114的信号的干扰电平。存储器102有一个ROM(只读存储器)和一个RAM(随机存取存储器)，ROM供存储控制程序和其它主要信息，RAM供存储微处理器100工作过程中产生的临时数据。由多个按键组成的按键输入部分104用以产生按键数据加到微处理器100上。Referring to FIG. 4, the overall functions of the mobile radiotelephone are controlled by microprocessor 100. Referring to FIG. Microprocessor 100 also displays on display 106 the RSSI of the signal received from signal level detector 110 and the interference level of the signal received from interference level detector 114 . The memory 102 has a ROM (read only memory) and a RAM (random access memory). The ROM is used to store control programs and other main information, and the RAM is used to store temporary data generated during the working process of the microprocessor 100 . The key input part 104 composed of a plurality of keys is used to generate key data to be sent to the microprocessor 100 .

所收到信号的RSSI和干扰电平在微处理器100的控制下显示在显示器106上。以下称显示RSSI的框条图为RSSI框条图，显示所收到信号的干扰电平的框条图为干扰电平框条图。参看图5，RSSI框条图以符号A表示，干扰电平框条图以符号B表示。上面说过，小框条单独显示出微弱的RSSI或干扰电平，小框条和中等框条在一起显示中等RSSI或干扰电平，三个框条一起，显示强RSSI或干扰电平。The RSSI and interference level of the received signal is displayed on the display 106 under the control of the microprocessor 100 . Hereinafter, the bar graph showing the RSSI is referred to as the RSSI bar graph, and the bar graph showing the interference level of the received signal is called the interference level bar graph. Referring to Fig. 5, the RSSI block diagram is represented by symbol A, and the interference level block diagram is represented by symbol B. As mentioned above, the small bar alone shows a weak RSSI or interference level, the small bar and the medium bar together show a medium RSSI or interference level, and the three bars together show a strong RSSI or interference level.

无线电部分108将通过调制解调器112收到的基带信号变换成射频信号，通过无线电信道传送给基地台，或将通过天线ANT收到的射频信号变换成基带信号传送给调制解调器112。无线电部分108有一个接收信号电平检测器110，检测所收到加到微处理器100的信号的RSSI。调制解调器112将音响信号处理器116来的音响信号变换成射频信号提供给无线电部分108，或将无线电部分108来的射频信号变换成基带信号提供给音响信号处理器116。特别是，调制解调器112有一个干扰电平检测器114检测无线电部分108来的射频信号的数据误差率从而产生所收到信号的干扰电平。音响信号处理器116与扬声器SPK及话筒MIC连接，将来自MIC的音响信号传送给调制解调器112或将来自调制解调器112的信号传给SPK。The radio part 108 converts the baseband signal received through the modem 112 into a radio frequency signal and transmits it to the base station through a radio channel, or converts the radio frequency signal received through the antenna ANT into a baseband signal and transmits it to the modem 112 . The radio section 108 has a received signal level detector 110 which detects the RSSI of the received signal applied to the microprocessor 100 . The modem 112 converts the audio signal from the audio signal processor 116 into a radio frequency signal and supplies it to the radio part 108 , or converts the radio frequency signal from the radio part 108 into a baseband signal and supplies it to the audio signal processor 116 . In particular, modem 112 has an interference level detector 114 which detects the data error rate of the radio frequency signal from radio section 108 to generate an interference level of the received signal. The audio signal processor 116 is connected to the speaker SPK and the microphone MIC, and transmits the audio signal from the MIC to the modem 112 or the signal from the modem 112 to the SPK.

现在参看图6更具体地说明所收到信号的RSSI和干扰电平的显示过程。微处理器100在步骤200确定所收到信号电平检测器110是否提供所收到信号的RSSI。微处理器100若收到有关RSSI的信息，就转入步骤202显示RSSI框条图，否则转入步骤204。在步骤202，若RSSI微弱，显示器106上就只显示小框条图，若RSSI中等，就一起显示小框条和中等框条，若RSSI强劲，就显示所有三个框条。接着，在步骤204，微处理器再次确定干扰电平检测器114是否提供所收到信号的干扰电平。微处理器100若收到有关干扰电平的信息就转入步骤206显示干扰电平框条图。同样，若干扰电平弱，显示器106上就只显示小框条图，若干扰电平中等，就小框条和中等框条一起显示，若干扰电平强，就显示所有三个框条。这之后，程序返回步骤200。因此，本发明提供了一种能正确告诉用户获得成功通信概率及造成该概率原因的移动无线电电话机。Referring now to FIG. 6, the display process of the RSSI and the interference level of the received signal will be described more specifically. Microprocessor 100 determines at step 200 whether received signal level detector 110 provides the RSSI of the received signal. If the microprocessor 100 receives the information about RSSI, it will go to step 202 to display the RSSI block diagram, otherwise it will go to step 204 . In step 202, if the RSSI is weak, only the small bar graph is displayed on the display 106, if the RSSI is medium, both the small and medium bars are displayed, and if the RSSI is strong, all three bars are displayed. Next, at step 204, the microprocessor again determines whether the interference level detector 114 provides the interference level of the received signal. If the microprocessor 100 receives the information about the interference level, it goes to step 206 to display the interference level block diagram. Likewise, if the interference level is low, only the small bar graph is displayed on the display 106, if the interference level is medium, the small and medium bars are displayed together, and if the interference level is high, all three bars are displayed. After that, the procedure returns to step 200 . Therefore, the present invention provides a mobile radiotelephone which can correctly inform the user of the probability of obtaining successful communication and the cause of the probability.
