5, C & M message parse

After getting tcp data stream, effective C & M message can be parsed from described tcp data stream.The embodiment of the present invention monitors C & M message, can not ensure in the listen mode to receive complete tcp data stream, and therefore, the embodiment of the present invention can obtain C & M message from incomplete tcp data stream.

The embodiment of the present invention can detect for heartbeat frame.The frame-skipping of C & M message center is one and compares the frame having feature, frame number 171 or 181, and length is definite value--0x0000000F.Can the frame head of preliminary judgement heartbeat frame according to these 8 continuous print bytes.After judgement frame head, check according to the form of C & M message, if correctly this message is sent to application interface.If discovery mistake, then think and again enter the state that heartbeat frame detects by synchronization loss.

Concrete, the described step parsing effective C & M message from described tcp data stream can comprise:

D1, extracts initial control and management message from described tcp data stream;

In the embodiment of the present invention, first can extract initial C & M message from above-mentioned tcp data stream, more initial C & M message be detected afterwards, parse wherein effective C & M message.

D2, detects heartbeat frame from described initial control and management message;

D3, judges that whether the form of the Frame after described heartbeat frame is correct;

D4, when correct, is defined as effective control and management message by described Frame;

D5, when incorrect, continues to detect heartbeat frame from described initial control and management message.

In the embodiment of the present invention, can detect according to the structure of C & M message, as shown in Figure 5, be the structural representation of C & M message.Concrete analytic method can with reference to Fig. 6, and described resolving can comprise:

Step 601, waits for heartbeat frame number 171 or 181 state;

First, can detect in described initial control and management message whether receive heartbeat frame number (namely 171 or 181), if receive described heartbeat frame number, then perform step 602.

Step 602, waits for heartbeat frame regular length state.

When receiving heartbeat frame number, can detect further and whether receiving heartbeat frame regular length (i.e. 0x0000000F), if receive heartbeat frame regular length, then can determine that frame corresponding to described frame number is heartbeat frame, and perform step 603.

Above-mentioned steps 601-step 602 can detect the process of heartbeat frame in corresponding d2 from described initial control and management message.

After detecting heartbeat frame, can be judged the form whether correct (d4) of the Frame after described heartbeat frame by step 603-step 611, this deterministic process is the judgement that the structure according to Fig. 5 is carried out.

Step 603, waits for frame number state.

This step mainly detects the frame number whether receiving correct Frame after described heartbeat frame.If receive the frame number of correct Frame, then step 604 can be performed; If the frame number received incorrect (such as frame number is not in normal range (NR)), then can determine that the form of this Frame is incorrect, and return step 601.

Step 604, waits for length condition.

If receive the length of Frame, then perform step 605, otherwise continue to wait for.

Step 605, waits for RRUID state.

If receive RRUID, then perform step 606, otherwise continue to wait for.

Step 606, waits for BBUID state.

If receive BBUID, then perform step 607, otherwise continue to wait for.

Step 607, waits for light slogan state.

If receive light slogan, then perform step 608, otherwise continue to wait for.

Step 608, waits for serial number state.

If receive serial number, then perform step 609, otherwise continue to wait for.

Step 609, waits for IE flag states.

When receiving the frame number of correct Frame, detect length, RRUID and BBUID and the light slogan and serial number that whether receive Frame successively.When receiving the length of Frame, RRUID and BBUID and light slogan and serial number successively, can detect and whether receive correct IE mark.

If receive correct IE mark, then step 610 can be performed; If IE mark incorrect (such as IE mark is not in normal range (NR)) received, then can determine that the form of this Frame is incorrect, and return step 601.

Step 610, waits for IE length condition.

When receiving correct IE mark, can detect further and whether receiving correct IE length.If receive correct IE length, then step 611 can be performed; If the IE length received incorrect (such as IE length is not in normal range (NR)), then can determine that the form of this Frame is incorrect, and return step 601.

Step 611, waits for IE data mode.

When receiving correct IE length, IE data mode can be waited for, and compare the length of IE length and Frame.

As can be seen from Figure 5, n IE can be comprised in each Frame.When IE length is less than the length of Frame, step 609 can be returned and detect next IE; When IE length equals the length of Frame (all IE have all detected, and the length of last IE just in time equals the length of Frame), determine that the form of described Frame is correct, and return step 603 and detect next Frame; When IE length is greater than the length of Frame, can determines that the form of described Frame is incorrect, and return step 601.

For each normal range (NR) above-mentioned, those skilled in the art can carry out relevant treatment according to practical experience, and the embodiment of the present invention is not limited concrete numerical value.

6, application interface represents

For the Frame that the form detected is correct, effective control and management message can be defined as, and be supplied to application interface and represent.In application interface, C & M message can be represented very intuitively, and, if find to occur mistake, then can carry out alarm prompt.

Such as, if it is B that BBU sends to the message of RRU to be the message that A, RRU should return to BBU, and the actual message returned is C, now namely occurs mistake, can carry out alarm.Further, can judge it is RRU side existing problems according to the C & M message monitored, therefore can safeguard RRU.

Finally, it should be noted that, above-mentioned ether packet, IP packet, tcp data bag and C & M message obtain respectively from the first data flow and the second data flow, and they have included the data of both direction.Because the processing procedure of the data for both direction is identical, the embodiment of the present invention is just introduced from entirety, but should be actually and carry out above-mentioned various process to the data of both direction respectively by distinct its.

In the process that the embodiment of the present invention can communicate at BBU with RRU, isolate the C & M message of both direction, by analyzing the C & M message of this both direction, the problem of BBU and RRU in communication process can be judged more exactly.
