Description

TERMINAL AND METHOD FOR DISPLAYING THE PROBABILITY OF ATTAINING SUCCESSFUL COMMUNICATION IN A MOBILE RADIO TELEPHONE Background of the Invention The present invention relates to a mobile radio terminal, and more particularly to a device for displaying the probability of attaining successful communication in a mobile radio terminal such as CDMA (Code Division Multiple Access) mobile radio telephone.

Conventionally, a mobile radio terminal displays a probability of attaining successful communication by continuously detecting the Received Signal Strength Indicator (RSSI) of a signal received from the base station. For example, such probability may be represented by three graphic bars which may be displayed on the LCD of the mobile radio terminal, as shown in Figs. 1 to 3.

If the detected RSSI is strong, indicating the highest probability of successful communication, all three bars which are respectively small, medium and large are displayed as shown in Fig. 3. Likewise, if the detected RSSI is medium or weak, respectively indicating relatively less or the least probability, the small and medium bars are displayed as shown in Fig. 2, or only the small bar as shown in Fig. 1.

However, the probability of attaining successful communication does not simply depend on the RSSI. : there is wave interference from adjacent channels or base stations, the probability is decreased even with the strong RSSI. For this reason, there has been proposed to take into consideration the data error rate of the received signal when displaying the probability. For example, if the detected RSSI is strong with a high error rate, the probability is displayed low. However, this does not correctly inform the user of the causes contributing to the probability of attaining successful communication.

Brief Description of the Drawings The objects, characteristics and scope of the present invention will be more fully understood with reference to the following description of certain embodiments, given by way of examples only, with reference to the accompanying drawings, in which: Figs. 1 to 3 are schematic diagrams illustrating graphic bars displayed on the LCD of a conventional mobile radio terminal, which represent the probabilities of attaining successful communication according to prior art ;- Fig. 4 is a block diagram illustrating the structure of a mobile radio telephone according to an aspect of the present invention; Fig. 5 is a schematic diagram for illustrating graphic bars displayed on the LCD of a mobile radio telephone according to an aspect of the present invention; and Fig. 6 is a flow chart for illustrating a process of displaying the probability of attaining successful communication of a mobile radio telephone according to an aspect of the present invention.

Detailed Description of the Drawings A mobile radio telephone according to an embodiment of the present invention preferably incorporates a device which enables the user to correctly perceive causes contributing to a probability of attaining successful communication. According to an aspect of the present invention, this may be achieved by separately displaying the RSSI and an interference level of a received signal.

Referring to Fig. 4 the functions of the mobile radio telephone may be controlled by a microprocessor 100. The microprocessor indicates on display 106 the RSSI of a received signal supplied from a received signal level detector 110. According to an aspect of the present invention, the microprocessor also, or alternatively, indicates on the display 106 the received signal interference level of the received signal supplied from an interference level detector 114. A memory device 102includes a ROM for storing the control program and other essential information and a RAM for storing temporary data generated during the operation of the microprocessor 100. A key input part 104 consisting of a plurality of keys serves to generate key data to be applied to the microprocessor 100.

The RSSI and/or interference level of a received signal are each displayed on a display 106 under the control of the microprocessor 100, for example, as shown in Fig. 5.

Graphic bars A, representing the RSSI, are referred to as RSSI graphic bars, and graphic bars B, representing the received signal interference level are referred to as interference level graphic bars. By analogy with the graphic bars of Figs. 1-3, described above, a small bar displayed alone represents a weak RSSI or, a high interference level, the small and medium bars displayed together represent a medium RSSI or interference level, and all three bars displayed together represent a strong RSSI or a low interference level.

Overall, each set of graphic bars may preferably be arranged to show a small bar to indicate a low probability of attaining successful communication; a small bar and a medium bar to indicate a medium probability of attaining successful communications; and all three bars to indicate a high probability of attaining successful communication.

A radio part 108 converts a baseband signal received through a modem 112 into a radio frequency signal to be transmitted through a radio channel to a base station.

Alternatively, a radio frequency signal received through- antenna ANT is converted into a baseband signal which is then transferred to the modem 112.

The radio part 108 includes the received signal level detector 110 for detecting the RSSI of a received signal, and supplying the detected RSSI to the microprocessor 100.

The modem 112 converts a microphone sound signal from a sound signal processor 116 into a radio frequency signal to be supplied to the radio part 108, or converts a radio frequency signal from the radio part 108 into a baseband signal to be supplied to sound signal processor 116 for supply to a speaker SPK.

In particular, the modem 112 includes the intqrference level detector 114, which detects a data error rate of the radio frequency signal from the radio part 108, to generate the received signal interference level, which it supplies to the microprocessor 100.

The sound signal processor 116 is connecte with a speaker SPK and microphone MIC to transfer the sound signal from MIC to the modem 112 or the signal from the modem 112 to SPK.

The process of displaying the RSSI and interference level of a received signal will now be more specifically described, with reference to Fig. 6.

Microprocessor 100 determines in step 200 whether the received signal level detector 110 supplies the RSSI of a received signal. If the microprocessor 100 receives the information concerning the RSSI, it goes to step 202 to display the RSSI graphic bars, or otherwise to step 204.

In step 202, the small RSSI graphic bar is displayed alone on the display 106 if the RSSI is weak, the small and medium RSSI bars are displayed together if the RSSI is medium, and all the three RSSI bars are displayed if RSSI is strong.

Subsequently, in step 204, the microprocessor determines whether the interference level detector 114 supplies the interference level of the received signal. If the microprocessor 100 receives information concerning the interference level, it goes to step 206 to display the interference level graphic bars.

Similarly to the process of step 202 the small interference level graphic bar is displayed alone on the display 106 if the interference level is high, to signify a reduced probability of successful communication. The small and medium interference level bars are displayed together if the interference level is medium, to signify a medium probability of successful communication. All three interference bars are displayed if the interference level is low, to signify a high probability of successful communication.

Thereafter, the process returns to step 200.

Thus, the invention provides a device and method for displaying a level of interference in mobile radio communications, on a portable mobile radio terminal. The invention also provides a mobile radio telephone whichenables a user to be correctly informed of the probability of attaining successful communication together with the causes contributing to the probability.

While the present invention has been described with reference to certain specific embodiments, by way of illustrative examples, it will be appreciated by those skilled in the art that various changes and modifications may be made without departing the scope of the present invention. In particular, the device and method of the present invention may be adapted to provide for the display of parameters other than RSSI and/or interference level. Two or more parameters may be displayed : Alternatively, only one parameter, such as interference level, may be displayed.

< The parameters may be displayed concurrently, on adjacent bar graphs. The parameters may alternatively be displayed one at a time, in turn, on a single bar graph.

The bar graph (s) may have more, or fewer, than three bars, and be controlled appropriately, by analogy with the three-bar bar graphs described.

Display devices other than bar graphs may be used: a numerical representation may be used, a single line of varying length, or a symbol of varying dimension or intensity. In particular, a variable indication method may be used for displaying the probabilities of attaining successful communication, using a digit, or an icon, or a graph or similar means. Display means other than LCD may be used. For example, each bar graph may be replaced by a tri-colour LED, each colour representing one of the three states shown in Figs. 1-3.
