In a first function, in the board state in the base station 12 and the control station 13, the control station 13 notifies the diagnostic apparatus 14 when the status information of the recently received board does not match the previous state value, The board 14 which does not change state is not informed to the diagnosis apparatus 14. Therefore, the amount of traffic between the control station 13 and the diagnostic device 14 can be reduced. Here, the status information is largely classified into three types (that is, not installed, normal, and abnormal), and NOT EQUIPPED is initialized (0), NORMAL is "1", and ABNORMAL is " 2 "respectively.

As a third function, the channel state information in the control station 13 outputs a state only when a state request command is made from the user of the diagnostic apparatus 14. Here, the channel state information informs the E1 channel and the TCB channel state information connected to the base station interface board, the Internet board, and the ATM interface board in the channel management task (RTC) of the control station 13. That is, the channel state information has a value of "0" when the idle state (IDLE), "1" when the busy state (BUSY).

As a fifth function, Figure 4s is a base station reception strength message, where the base station reception strength (Rx) represents a pilot strength value received from the terminal every 1 second.

5A and 5B are flow charts of an embodiment of a system data processing method in a data communication interface block (DCI) in a diagnosis device (DM) according to the present invention, wherein the data communication interface block 22 in the diagnosis device 14 is shown. The real-time processing process until the message received from the control station 13 is processed in real time and handed over to each application block 231 to 236 of the application software block 23 is shown.

The data communication interface block 22 periodically accesses the communication port and receives data from the control station 13.

As shown in Figs. 5A and 5B, at a data communication interface block (DCI) 22 in a diagnostic apparatus (DM) 14 for processing in real time a message received from a control station 13 according to the invention. The system data processing method first substitutes the number of character strings in the input buffer arriving at the communication port into the buffer count variable BufferCnt (501), and arrives from the control station 13 in the string information variable StrInfo. If the input message of the communication port is substituted (502) and the string information variable (StrInfo) is substituted into the byte array variable (BytArr) (503), each character is stored as an ASCII value in the byte array variable (BytArr).

Thereafter, since one argument in the byte array variable BytArr is an ASCII value, the argument is converted into a corresponding character and stored in the string information variable 2 (StrInfo2) (504).

The reason for the hassle of storing the byte array variable (BytArr) is to handle the value "0". That is, when there is a value of "0" in the middle of the message string coming from the control station 13, if this column value is to be read and stored immediately in the new string information variable 2 (StrInfo2), the value of "0" is truncated. It should be processed after storing as ASCII value in (BytArr).

The string information variable 2 (StrInfo2) should be a message conforming to the protocol promised between the diagnostic device 14 and the control station 13, but the data communication interface block 22 does not receive data at the input port at the time when a portion of the message arrives. It can also be read and passed to an InputProcess. Thus, once data is stored in a queue, protocol-compliant messages are found and processed in the queue. At this time, the processing order is as follows.

First, a data start signal of a message according to a protocol is inserted into a start flag StartFlag, and a data end signal is substituted into an end flag EndFlag (505).

Thereafter, a true value is first assigned to a Boolean variable MessageExist that checks whether a message exists (506).

Next, the string information variable 2 (StrInfo2) is connected after the string buffer StrBuf declared as static (StrBuf = StrBuf + StrInfo2) (507).

Finally, as long as a message exists in the string buffer StrBuf, the message is continuously found and passed to the message processing block (508 to 517). Here, the processing order of the messages is FIFO (First In Fist Out) in the order stored in the string buffer StrBuf, that is, in the form of a queue.

Looking at the processing process, first find the position of the first message start signal from the front of the string buffer (StrBuf) and assign it to the start point variable (StartPos) (508), and find the position of the message end signal first encountered from the front of the string buffer (StrBuf). It is assigned to the end point variable EndPos (509).

After that, the start point variable StartPos is not 0 (that is, the start signal exists in the string buffer StrBuf), and the end point variable EndPos is not 0 (that is, the end signal exists in the string buffer StrBuf). In step 510, it is analyzed whether the value of the start point variable StartPos is smaller than the value of the end point variable EndPos (that is, whether the position of the start signal is located before the position of the end signal).

As a result of analysis, if the start signal and the end signal exist and the position of the start signal is located before the end signal, this condition means that a message conforming to the protocol exists in the string buffer (StrBuf). After (MessageLen = EndPos- (StartPos + 2)) 511, the message is found in the string buffer StrBuf and passed to the message processing block (512). Subsequently, the string buffer StrBuf cuts out the found message and substitutes the lower string (513), and then determines whether the value of the Boolean variable (MessageExist) that checks the existence of the message is True (517). ).

As a result of analysis, if the start signal and the end signal exist and the position of the start signal is not located before the end signal, the start point variable StartPos is not 0 (that is, the start signal exists in the string buffer StrBuf). Whether the end point variable EndPos is not 0 (i.e., the end signal exists in the string buffer StrBuf), and the value of the start point variable StartPos is greater than that of the end point variable EndPos (i.e., It is checked whether the position is located after the position of the end signal (514).

If the start signal and the end signal exist and the position of the start signal is located after the end signal, this condition occurs when a message that does not comply with the protocol is entered. Therefore, the start signal is ignored and the start signal is generated. After assigning the string after position to the string buffer (StrBuf) (StrBuf = Mid (StrBuf, StartPos)) (515), it is determined whether the value of the Boolean variable (MessageExist) that checks for the existence of a message is true. (517).

As a result of the test, if the start signal and the end signal do not exist, or if the position of the start signal and the end signal are the same, the message does not exist. Therefore, a false value is assigned to the Boolean variable (MessageExist) confirming the existence of the message. Later (516), it is determined whether the value of the Boolean variable (MessageExist) for checking the existence of the message is True (517).

If the value of the Boolean variable (MessageExist) that checks the existence of the message is true, it means that the message exists. Therefore, the message is continuously searched for as long as the message exists in the string buffer (StrBuf). Pass it to the processing block (508 to 517), and if it is False, it ends.
