BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
FIG. 1 shows a configuration of a mobile communication system to which an embodiment of the present invention is applied. The mobile communication system includes mobile station devices 1 and 1n capable of transmitting and receiving data, base station devices 2 and 2n connected to the mobile station device via a wireless channel, and wireless channels and calls between the base station device and the mobile station device. And a line control station device 3 connected to a switching network 4 for controlling connection of the data terminal and connecting to another data terminal (not shown).
[0014]
The mobile station device 1 includes a memory 11 for storing a program for operation control of the mobile station device, and a central processing unit 12 corresponding to a computer that reads a program from the memory 11 and controls the operation of each unit of the mobile station device. Prepare. When transmitting a plurality of numerical data, the central processing unit 12 decomposes each of the numerical data and forms the data into a predetermined format. The central processing unit 12 receives the transmission data transmitted from the other party and receives the original numerical data. And a data restoration control unit 121 for restoring the data. The line control station device 3 includes a memory 31 and a central processing unit 32. The central processing unit 32 includes a data decomposition control unit 321 and a data restoration control unit 322. These units have the same names as those of the above-described mobile station device 1. Since the function is the same as that of each part, the description is omitted.
[0015]
Referring to FIG. 2, details of the data decomposition control unit 321 in FIG. 1 are shown. The data decomposition control unit 321 includes a basic data selection unit 3211, a difference processing range setting unit 3212, a difference calculation processing unit 3213, and a transmission data forming unit 3214. The basic data selection unit 3211 selects the basic data that is the median value or a value before and after the median value among the plurality of numerical data to be transmitted. The difference processing range setting unit 3212 determines a maximum difference value between each piece of numerical data to be transmitted and the basic data.
[0016]
The difference calculation processing unit 3213 calculates a difference value from each of the numerical data based on the basic data, and sets the identification bit to 1 if the result is positive, and sets the identification bit to 0 if the result is negative. According to the result of the difference calculation processing unit 3213, the transmission data forming unit 3214 forms the difference information between the number of the numerical data, the difference value between the respective numerical data and the identification bit, and the difference data with the identification bit. The bit string is set within the range determined by the unit 3212.
[0017]
Referring to FIG. 3, details of the data restoration control unit 121 in FIG. 1 are shown. The data restoration control unit 121 includes a reception data analysis unit 1211, a basic data acquisition unit 1212, a back calculation unit 1213, and a data restoration unit 1214. The reception data analysis unit 1211 analyzes the contents of data transmitted from the other party. The basic data acquisition unit 1212 acquires basic data based on the analysis result of the reception data analysis unit 1211, and also acquires the number of pieces of difference information and each piece of difference information. The difference inversion processing unit 1213 determines each difference value based on the identification bit from each difference information acquired by the basic data acquisition unit 1212, and performs an addition process with the basic data.
[0018]
The data restoration unit 1214 performs restoration processing to the original numerical data after completion of the addition processing in the difference back calculation processing unit 1213. Since the difference value is generated based on the central data based on the basic data, the difference value is represented by a positive number and a negative number. Positive and negative are represented by one bit, and are set for each difference value. The line control station device or the mobile station device on the receiving side performs an inverse calculation of the difference processing based on the basic data to restore the numerical data.
[0019]
The unit information length is set as a system parameter in the line control station device 3 and the mobile station device 1. The unit information length is a processing unit length, and the transmission information length is formed by this unit or n times the unit information length. Further, a range in which the numerical data can be processed is set in the line control device 3 and the mobile station device 1. This difference processable range is for determining the maximum difference value with the basic data from which the difference value is calculated, and it is necessary to determine the difference value in a system employing this function.
[0020]
Further, the difference processable range also determines the maximum value of the bit length for setting the difference value. The smaller the range in which the difference can be processed, the shorter the bit string for setting the difference value, and thus the smaller the amount of data transmitted in the wireless section. When there are a plurality of numerical data to be transmitted, one of the numerical data groups is used as basic data to calculate a difference value from other information. By setting the difference value in a bit string set in the difference processable range, the signal is transmitted to the wireless section. However, this method requires that the difference value between the basic data and the other numerical data, that is, the difference processable range is smaller than the bit length of the basic data.
[0021]
This difference value is calculated by the line control station device 3 that generates information and transmitted to the base station device 2. Further, the base station device 2 transmits the information to the mobile station device 1 using radio. The mobile station device 1 that has received the data performs back calculation from the information to obtain the original numerical data. The same applies to the case where the signal is transmitted from the mobile station device 1. The difference value is calculated by the mobile station device 1, passes through the base station device 2, and is inversely calculated by the line control station device 3 to obtain the original numerical data.
[0022]
Next, the flow of data processing when transmitting data in the present embodiment will be described with reference to FIG.
[0023]
First, the case where the line control station device transmits numerical data to the mobile station device will be described. The circuit controller receives a plurality of numerical data to be transmitted from another data terminal via the switching network (Step 51 in FIG. 5: abbreviated as S51; the same applies hereinafter). The line control station apparatus retrieves and selects the centrally located numerical data from the plurality of received numerical data, and sets the selected numerical data as basic data (S52). This basic data is data from which a difference value is calculated with other numerical data, and may be any numerical value among a plurality of numerical data. However, a central value or a value before or after the central value is preferable because the difference value is not increased.
[0024]
Next, the process proceeds to a difference calculation process with each numerical data. A difference value from each numerical data is calculated based on the basic data (S53). At this time, whether the difference calculation result is positive or negative is determined (S54). If the result is positive, 1 is set to the positive / negative identification bit (S55). If the difference calculation result is negative, the positive / negative identification bit remains at 0 (S56). When the calculation of the difference value with each numerical data and the assignment of the positive / negative identification bit are completed (S57), the transmission data is formed as shown in FIG. 4 (S58).
[0025]
In the transmission data to be formed, the basic data is set at the top, indicates the number of data to be transmitted subsequently, and thereafter, a difference value with other numerical data is set as difference information 1 to n together with positive / negative identification bits. Further, the bit length of the difference information is determined in the range in which the difference can be processed. When the transmission data is formed, the transmission data is transmitted to the base station device and transmitted to the mobile station device using radio (S59).
[0026]
Next, a flow of data processing when receiving data according to the present embodiment will be described with reference to FIG.
[0027]
The mobile station device receives data transmitted from the line control station via the base station (S61 in FIG. 6), analyzes the received data (S62), and acquires basic data from the data (S63). Next, the number of pieces of difference information set in the received data is grasped (S64). A difference value amount is determined based on the acquired difference information using the positive / negative identification bit, and the difference value is inversely calculated, that is, added (S65). The sum of the basic data and the difference information is calculated, the calculation of all data is completed (S66), and the original numerical data is restored.
[0028]
Note that the procedure for transmitting data from the mobile station apparatus to the line control station apparatus is the same as the above-described procedure, and a description thereof will be omitted.
[0029]
Next, a processing operation when data transmission and data restoration are performed will be described using a specific example of simple numerical data.
[0030]
First, on the transmitting side, the numerical data to be transmitted is four pieces of "20, 21, 22, 23, 24". In this case, “22” is selected as the basic data because it is not the median but is a numerical value around this intermediate value. Next, each numerical data is converted. The conversion of “20” is 20−22 = −2, so that the transmission data (difference information) is 0, 2. Similarly, the conversion of “21” is 21−22 = −1. 0,1. The conversion of “22” is 22-22 = 0, so that the transmission data is 0, 0, and the conversion of “23” is 23-22 = + 1, so that the transmission data is 1, 1. Therefore, the transmission data is “22, 4, 0, 2, 0, 1, 0, 0, 1, 1”. Note that the difference possible range depends on the number of bits of difference information of transmission / reception data.
[0031]
On the other hand, the receiving side receives the data “22, 4, 0, 2, 0, 1, 0, 0, 1, 1”. Next, it is recognized from the received contents that "22" is the basic data and the number of data is four. Then, the original numerical data can be easily restored by performing the inverse calculation of the above-described procedure.
[0032]
【The invention's effect】
As described above, according to the present invention, a central value or a basic data which is a value before and after a plurality of numerical data to be transmitted is selected from an original numerical data group, and a difference value with each numerical data is calculated. Therefore, when transmitting and receiving data, the information amount of the entire original numerical data is reduced. Accordingly, the amount of information to be transmitted in the wireless section is reduced, so that the information transmission time is shortened, and the efficiency of the wireless section can be improved.
