Description

Dialing method based on expected value in wireless terminal {METHOD FOR DIALING BY EXPECTATION VALUE IN CORDLESS PHONE}

The present invention relates to a dialing method in a wireless terminal, and in particular, calculates an expected value by assigning a weight according to the frequency of call and the elapsed time since the last call, displays the telephone numbers in the order of the expected values, and dials when the user selects the telephone number. It is about how to do it.

In general, for dialing in a wireless terminal having a phone book function, a user performs a dialing operation by searching for a corresponding number by sequentially searching a recently dialed number with a direction key. Alternatively, the stored memory number can be directly searched using the arrow keys and the number can be dialed. In addition to the above cases, when the user does not remember the telephone number to dial, the user inputs a part of the name and searches for the telephone number among the stored names to perform dialing. Or, if the search results are many phone numbers, the corresponding number is sequentially searched and the corresponding number is sent. However, these functions simply use the data storage function. Therefore, a user needs to find a desired telephone number by inputting a key several times. If the user already knows the telephone number, the dialing operation by searching requires more key input than the direct key input.

Accordingly, an object of the present invention is to provide a method for minimizing key input when a user makes a phone call.

Another object of the present invention is to provide a method for predicting and displaying a telephone number to be input when a user inputs a telephone number.

Still another object of the present invention is to provide a method of calculating an expected value when displaying a telephone number and displaying the telephone number according to the expected value.

In order to achieve the above objects, the present invention includes a memory for storing a name, a telephone number corresponding to the name, a frequency of calling the telephone number, and an elapsed time after the last call of the telephone number, and one dial digit. Expected value according to the first process of inputting a second process, a second process of reading a telephone number corresponding to a dial digit input so far, from a memory, and the frequency of transmission of each read telephone number and the elapsed time since the last call. A third process of calculating a; and a fourth process of sequentially displaying each phone number according to the calculated expected value; and checking whether a dialing key is input when a key for selecting one of the displayed phone numbers is input. A fifth process and a sixth process of returning to the first process if a key for selecting one of the displayed telephone numbers is not input; When the dial type linkage is characterized by dialing the selected phone number and constituted by any process of claim 7, back to the first step if the dialing key is entered.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Specific details appear in the following description, which is provided to aid a more general understanding of the present invention. It should be understood by those skilled in the art that the present invention may be practiced without these specific details. It will be self explanatory. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a wireless terminal according to an embodiment of the present invention.

The controller 100 of the wireless terminal controls the overall operation of the wireless terminal. The memory 130 includes a ROM that stores an operating program, an electrically programmable EEPROM, and a RAM. The memory 130 stores a name, a telephone number corresponding to the name, a frequency of calling the telephone number, and an elapsed time since the last call of the telephone number. The display unit 120 is a display device such as a liquid crystal display (LCD). The display unit 120 displays the state of the wireless terminal or the progress of the program under the control of the controller 100. The key input unit 110 includes a plurality of numeric keys and function keys for performing various functions, and outputs key data to the controller 100 by an external operation. The RF unit 150 is controlled by the controller 100 and transmits a signal output from the controller 100 through an antenna. In addition, the RF unit 150 converts the wireless signal received through the antenna into a desired signal and outputs it. The signal processor 140 modulates the voice signal input from the microphone and converts the voice signal into voice data, and demodulates the voice data input from the RF unit 150 into a voice signal and outputs the voice signal through a speaker.

Before looking at the flowchart of FIG. 2, a memory phone of a general telephone number and a memory phone according to the present invention will be described. First, the memory numbers of common telephone numbers are organized as shown in Table 1.

However, in the present invention, in addition to the name and phone number shown in Table 1, the frequency of the call, the time of the final call is stored together. The last call time is continuously updated when a call is made. A memory chip according to the present invention is shown in Table 2 below.

2 is a control flowchart for dialing according to an embodiment of the present invention.

Looking at the contents of the schematic flowchart first, whenever a user enters a phone number, the phone number corresponding to the entered number is searched. The expected value of the searched phone number is calculated and displayed on the display unit 120 in proportion to the expected value. The expected value refers to an expectation that a specific telephone number is expected to be input by the user. The user then selects the desired phone number and attempts to dial if there is a desired phone number.

In step 200, the controller 100 checks whether a dial digit value corresponding to one number is input through the key input unit 110. If one dial digit is input, the process proceeds to step 210. In step 210, the first digit value received through the key input unit 110 is checked to be a value corresponding to “0”. The first digit "0" generally means the first digit of the area code that the user must enter in order to make a call on the wireless terminal. Therefore, if the first digit is the value corresponding to "0", the search is executed. However, since it is difficult to serve as a parameter, the search is not executed when the value of the first digit is "0". However, if the first digit does not enter a value of "0", the search operation starts. In this case, the search is executed when the auto dial mode is set or when communication between the same communication service companies is not required to press an area code or a number such as "019" or "017". In step 220, the controller 100 checks whether there is a phone number corresponding to the digit inputted from the memory 130 and reads out the corresponding phone number. In step 230, the control unit 100 calculates an expected value according to the source frequency and the final call time. The expected value is equal to the value that the user may enter next time.

Explaining how to calculate the expected value can be done by simply considering the frequency of transmission or final call time. However, this method is less likely to guess the phone number that the user can enter. Therefore, it is necessary to calculate the expected value considering both the frequency of call and the time elapsed since the last call. In addition, in order to increase the hit rate, two additional factors are required in addition to the frequency of transmission and the elapsed time since the last transmission. The two factors are constant values that are multiplied by the frequency of the source frequency and the inverse of the elapsed time since the last call. The above factor is to predict the number that the user can input more accurately. That is, in order to optimally increase the hit ratio. If the calling frequency is expressed as C, and the final calling time is subtracted from the current time, and the reciprocal value is assumed to be T, then C is large when the calling frequency is large, and T is small when the elapsed time is long.

In Formula 1, "A" refers to a constant number. The T value can also be obtained by the following equation.

T = A-Current Time-Last Call Time

In Equation 2, "A" refers to a constant number. "Current time-end call time" in Equation 1 or 2 refers to "elapsed time after last call".

Whenever a telephone number is used by the above equation, the values of C and T change. However, these C or T values do not apply to user habits. So by multiplying C and T by a certain value, we can get closer to the user's habits. For example, if there are people who regularly talk to a certain account, the weight value multiplied by the T value should be set less. On the other hand, if there is a telephone number that is frequently called, the weight value for C and the weight value multiplied by T should be set to the same level. In addition, the weighting of T should be set higher when several callers talk intensively for a certain period of time. Examples of the weight may be 100, 10, 1, 0.9, 0.5, 0.1, and the like.

Let the first weight multiplied by C be Cw and the second weight multiplied by T be Tw. The hit rate can then be increased on average by applying different values of Cw and Tw. Therefore, the expected value can be obtained by the following equation.

Expected value = (T * Tw) + (C * Cw)

In operation 240, when the expected value is obtained, the controller 100 sequentially displays the telephone number through the display 120 according to the expected value. At this time, the user can search the displayed phone number by using the arrow keys. If you find a phone number you want, you will select that number. In step 250, the controller 100 checks whether a key value input through the key input unit 110 is a key for selecting a phone number. If no key value is selected to select a phone number, go back to step 200 and continue to input the next digit. Keep doing this until you get the number you want. If a key for selecting a phone number is input in step 250, in step 260, the controller 100 outputs a message asking whether to dial the corresponding phone number through the display 120. The dialing request message may be displayed, for example, "Do you want to dial the selected telephone number? Y / n". As in step 250, if a key for dialing is not input, the process returns to step 200. When the dialing key is input, the controller 100 dials the selected phone number in step 270. Even if the message for dialing is not displayed, when the send key is pressed, the selected telephone number is dialed.

In the embodiment of the present invention, the expected value is calculated and displayed every time the dial digits are input one by one, but even under the general circumstances, the expected value can be calculated and the telephone number can be displayed accordingly.

Similarly, in the exemplary embodiment of the present invention, the expected value is calculated and displayed every time the dial digits are input one by one. However, the phone number having the input number may be displayed in any order without calculating the expected value. The arbitrary order may be the order stored in the memory, the last use time or the order of the telephone number.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention searches the phone book whenever one phone number is input, displays the phone number in proportion to the expected value, and when the corresponding phone number is selected, dials the selected phone number, thereby allowing the user to dial. Minimize the keystrokes you had to press to
