Abstract

PURPOSE: A data generating and transmitting method is provided to improve upper processor performance without revising of a hardware by reducing the amount of signal data transferred between an upper processor and a link line device. CONSTITUTION: A data generating and transmitting method is described which comprises a transmission algorithm. The transmission algorithm comprises initializing a program for data transmission(S100). A 16-byte data is generated by comparing previous signal data with current signal data in an upper processor(S200). A 2-byte data is generated by comparing the 16-byte data with a set byte number(S300). After transferring the 2-byte data at the upper processor(S400), whether the 16-byte data is transferred is judged according to comparison of the transferred 2-byte data(S500). If the 2-byte data is identical to a set value, the procedure goes to the step(S500). If the 2-byte data is not identical to the set value, varied signal data is only transferred(S600).

FIG. 2 is a flowchart illustrating a data generating method in a method for generating and transmitting data between an upper processor and a trunk line apparatus. Is a flowchart illustrating a transmission method in a data transmission method between an RS and a relay apparatus.

4 is a flowchart illustrating a data generation method in a data generation and transmission method between an upper processor and a trunk line device, and FIG. 5 illustrates a transmission / reception data format between a higher processor and a relay line device in a data transmission method between the upper processor and the trunk line device. Table shown.

As shown in FIG. 1, first, the relay line apparatus 200 receives signal data transmitted / received during an exchange period (not shown) when a subscriber attempts to make a call to an unsubscribed subscriber. It transmits to the upper processor 100, transmits the signal data received from the upper processor 100, and monitors the status of the channel and reports to the upper processor 100.

In addition, the upper processor 100 controls the voice data transmitted through the switch (not shown) to be transmitted through the normal path from the relay line device 200, and the relay line device 100 so that the call can be made normally. It serves to control.

Hereinafter, an operation process of the data generation method in the data generation and transmission method between the upper processor and the relay line device configured as described above will be described.

If the program for data comparison is initialized in order to transmit data from the upper processor 100 or the trunk line apparatus 100, that is, for example, to generate data in the upper processor 100 (S1), the input signal The data is compared with the data input in the past (S2).

Subsequently, if the newly input signal data is the same as the data input in the past in the data comparison determination step (S2), the carry flag value is set to 0, for example, so that the signal data is the same in the upper processor 100. (S3), if the newly input signal data in the data comparison determination step (S2) is not the same as the data input in the past, carry so that the upper processor 100 knows that the signal data is not the same. For example, the flag value is set to 1 (S4).

Then, as shown in FIG. 5B, the upper processor 100 stores the change of the channel in the first and second flag setting steps S3 and S4, so that the carry flag value is stored in the memory space. It is inserted and stored in one byte (S5), and counts eight times whether all of the carry flags are stored, and it is determined whether or not the carry flag value is a set value (S6).

In addition, if the set flag value is not counted by counting eight times in the first flag determination step S6, the location of the memory is moved to compare the next input signal data with the previously input data (S7). If the set flag value is found in the flag determination step, it is determined whether all channels of 16 bytes are stored (S8).

Subsequently, if all 16-byte channels are not stored in the storage determination step (S8), the process returns to the memory location shifting step. If all of the channels are stored, the upper processor 100 returns 2 bytes as shown in FIG. 5A. Initialize to generate the data of (S9), and compares the generated 16 bytes in units of 1 byte to determine whether or not (S10).

In this case, the carry flag value is set to determine whether the data is 0 in the second flag determination step (S10) (S11), and the carry flag value is set so that the data is not 0 in the second flag determination step. It is set (S12).

Meanwhile, in order to store the carry flag set in the third and fourth flag setting steps S11 and S12 in 2 bytes, the carry flag value is inserted into the memory space and stored one by one (S13), and the carry flag is stored in 1 byte. 8 is counted whether all are stored, and it is determined whether the carry flag value is a set value (S14).

In addition, if the set carry flag value is not counted by counting eight times in the third flag determination step (S14), the location of the memory is moved to compare the next input signal data with the previous input data (S15). It is determined whether all channel data of the byte are stored (S16).

Subsequently, if all channels of 2 bytes are not stored in the second storage determination step (S16), the process returns to the memory position shifting step (S15). If all of the channels are stored, the channel search of 2 bytes is performed and initialized (S17). ).

Hereinafter, an operation process of a transmission method in the data generation and transmission method between the upper processor and the relay apparatus configured as described above will be described.

After initializing a program for data transmission in order to transmit signal data from the upper processor 100 or the relay line device 200, that is, the upper processor 100 (S100), the upper processor 100 is past. The first data having a predetermined number of bytes, for example, 16 bytes is generated by comparing the input signal data with the currently input signal data by setting bits (S200).

Subsequently, when the first data is generated in the first data generation step (S200), the upper processor 100 compares the set number of bytes to generate the second data, for example, two bytes of data (S300). After generating the values of the second and second data, the upper processor 100 transmits the second data (S400).

In addition, by comparing the value of the second data transmitted from the upper processor 100 to determine whether to transmit the first data (S500), in the data transmission determination step (S500), the second data and the set value If the same, the upper processor 100 returns to the data transmission determination step, and if the second data is not the same as the set value, only the changed signal data is transmitted (S600).

Hereinafter, an operation process of the reception method in the data generation and transmission method between the upper processor and the relay apparatus configured as described above will be described.

After initializing a program for receiving data in order to receive signal data from the upper processor 100 or the trunk line device 200, that is, the relay line device 200 (S1000), the relay line device 200 The changed signal data, that is, the second data transmitted from the upper processor 100 is received (S2000).

Then, the relay line apparatus 200 analyzes the second data transmitted from the upper processor 100 to determine whether the first data includes the same data as the data input in the past (S3000).

Subsequently, if there is the same data in the same data determination step (S3000), the process returns to the same data determination step, and if there is no identical data, the first signal data is received (S4000), and the upper processor 100 in the relay line apparatus 200 is received. After receiving the changed data, that is, the first data transmitted from the), it is processed and processed (S5000).

As described above, the method for generating and transmitting data between the upper processor and the trunk line apparatus of the present invention reduces the load of the upper processor by reducing the amount of signal data transmitted / received between the upper processor and the trunk line apparatus, thereby replacing the upper processor. There is an effect that the performance of the upper processor can be improved without modifying hardware, and the upper processor can easily perform more work and other tasks.
