Fig. 2 is that as shown in Figure 2, this method mainly may further comprise the steps (step S202-step S206) according to the flow chart of the detection method of the optical fiber connection of the embodiment of the invention:
Step S202, baseband processing unit (BBU) send to the Remote Radio Unit (RRU) of connecting with the light mouth through its light mouth and detect sequence;
In practical application, BBU has higher information processing capability usually, in order to make full use of base-band resource; Baseband board generally is set on each BBU at least; A plurality of light mouths can be set on each baseband board, for example, three light mouths can be set on a baseband board;
At present, can series multistage RRU under each light mouth, and every grade of RRU has only a RRU, and visible, what grade RRU are arranged under each light mouth, what RRU are also just arranged.In practical application, the 3 grades of RRU that connect at least under each light mouth usually also are to connect 3 RRU under each light mouth at least.
In embodiments of the present invention; When the optical fiber hybrid junction occurring between a plurality of light mouths; Information transfer service will Presence information be transmitted azygous situation, and therefore, BBU send to detect sequence (promptly be used for detection fiber whether connect the information of wrong) through each light mouth to RRU.In a preferred implementation of the embodiment of the invention, detect the light mouth for the ease of BBU and whether make mistakes, BBU is different through the detection sequence that each light mouth sends.Send the A sequence such as, the BBU RRU under a light mouth, then simultaneously under another light mouth RRU send the B sequence, wherein the content and/or the length of A sequence and B sequence are inequality.
In embodiment of the invention preferred embodiment, BBU can comprise through the detection sequence that each light mouth sends; The light slogan information of this light mouth on the slot number information of sequence head, light mouth place baseband board and the baseband board.Thereby can be so that BBU has nothing in common with each other through the detection sequence that different light mouths sends.
Judge for the ease of BBU, reduce complexity, in a preferred implementation of the embodiment of the invention, the detection sequence that BBU sends to the RRU at different levels of series connection under the same light mouth is identical.
In embodiments of the present invention, BBU is after RRU sends the detection sequence, and the detection sequence that RRU will receive returns to BBU as feedback sequence through the light mouth that is connected with RRU.RRU under BBU light mouth is merely one-level, and when promptly only having connected a RRU under this light mouth of BBU, RRU postbacks its detection sequence that receives to BBU after receiving the detection sequence.
If be in series with multistage RRU under the same light mouth, BBU can send the detection sequence respectively to each RRU, in the detection sequence of sending, carries the ID of the RRU that receives this detection sequence; Perhaps, BBU also can be simultaneously sends sequences to RRU at different levels, through in advance with the agreement of RRU at different levels, indicate the position of the detection sequence of RRU at different levels.
For example, in practical application, suppose to detect sequence and comprise N bit; Be in series with M RRU under the light mouth of BBU, wherein, M and N are the integer more than or equal to 1; Then BBU is passing through its light mouth when RRU sends the detection sequence, can send length through this light mouth and be the subsequence of M bit, wherein; Each bit in the M of this subsequence the bit corresponds respectively to a RRU among M the RRU; The value of each bit is that BBU sends in the detection sequence of corresponding RRU, and above-mentioned steps is carried out in circulation, will send to the detection sequence of N bit transmission completion of each RRU the light mouth under according to the order of sequence until BBU.In this case; For one of them RRU among the above-mentioned M RRU, when RRU receives subsequence, obtain the bit that BBU sends to the detection sequence of this RRU from the correspondence position of subsequence; Return one to said BBU and longly be the subsequence of M bit; With the value of the correspondence position of said RRU value, this bit is returned to BBU, in this subsequence if there is next stage RRU in this RRU for the said bit that from the said subsequence that receives, obtains; Then RRU is transmitted to next stage RRU with the subsequence that receives; Then N of receiving that RRU returns of BBU is long be the subsequence of M bit, respectively from said N individual long be that the position corresponding with said RRU of the subsequence of M bit obtains N bit, obtain said feedback sequence.
In practical application, can communicate according to interface protocol between BBU and the RRU, when RRU returns feedback sequence to BBU; The index that can comprise this BBU in this feedback sequence; BBU is known the RRU that returns feedback sequence according to the index of this RRU, according to the corresponding relation that is provided with in advance, is the value that position corresponding with this RRU the subsequence of M bit obtains the bit that this RRU returns from the length of feedback; After receiving for N time, get access to the feedback sequence that this RRU returns.For example; Agreement specified standard interface is followed in communication between BBU and the RRU, suppose to have 10 bytes, and the sequence content that is used for optical fiber wrong detection has only accounted for wherein 4 bytes; The index information that has comprised corresponding RRU in other 6 bytes; When RRU returned feedback sequence, it comprised this index information in the information that BBU sends, thereby makes BBU can know that which RRU beams back.
Wherein, detect sequence and comprise: sequence head, the slot number information of light mouth place baseband board and the light slogan information of baseband board glazing mouth, wherein, BBU is all identical through the sequence head of the detection sequence that each light mouth sends.
Step S204, BBU receives the feedback sequence that RRU returns through the light mouth;
Step S206, whether BBU is consistent with the detection sequence of sending through the light mouth through the feedback sequence that judgement receives, and whether the optical fiber that detects this RRU connects normal.
In embodiments of the present invention, BBU is judging feedback sequence that RRU returns and the detection sequence of sending through the light mouth when inconsistent, and the optical fiber of confirming this RRU connects makes mistakes.
In a preferred implementation of the embodiment of the invention, for the ease of statistics, when BBU made mistakes in the optical fiber connection that detects certain RRU, the optical fiber that can write down this RRU connected the number of times of makeing mistakes.
In another preferred implementation of the embodiment of the invention, when the optical fiber connection that detects certain RRU made mistakes, BBU can report corresponding warning information, connected the information of makeing mistakes thereby the attendant can in time get access to the optical fiber of certain RRU.Preferably; Frequency for fear of alarming information report is too high; In a preferred implementation of the embodiment of the invention, the optical fiber that BBU can periodically detect each RRU connects the number of times of makeing mistakes, if RRU at preset (for example; 5) optical fiber in the consecutive periods connects the number of times of makeing mistakes and exceeds threshold value and be connected the number of times of makeing mistakes less than threshold value with the optical fiber of last RRU at different levels under the same light mouth of RRU, then reports the warning information of the optical fiber connection error of this RRU.
In embodiments of the present invention; Just often whether BBU connect at the optical fiber that detects between RRU; BBU judges whether the sequence head of the said feedback sequence that RRU returns is consistent with the sequence head of the said detection sequence of sending through said light mouth; If; Whether the light slogan information of slot number information and the above light mouth of baseband board that light slogan information and the light mouth of said detection sequence of slot number information and the above light mouth of baseband board of then judging the light mouth place baseband board of said feedback sequence belongs to baseband board is consistent; If the slot number information of both light mouths place baseband board and the light slogan information inconsistency of the above light mouth of baseband board confirm that then the optical fiber connection of said RRU makes mistakes.
Through the said method that the embodiment of the invention provides, the optical fiber that BBU can detect each grade RRU under each light mouth automatically connects the information of makeing mistakes, and locatees fast thereby can make mistakes to optical fiber, has guaranteed normally carrying out of communication service.
Fig. 3 connects the flow chart that detects according to the optical fiber to each light mouth in the preferred embodiment of the present invention, and as shown in Figure 3, to each light mouth, BBU and RRU can carry out following steps (step S302-S310):
Step S302, BBU each RRU under each light mouth sends sequence data (being Bit data);
In embodiments of the present invention; The BBU RRU under each light mouth respectively sends sequence data, and for example, sequence data is generally the binary bits data; This sequence data (being above-mentioned detection sequence) contains three partial informations: sequence head (Head), light mouth place baseband board slot number (SlotNo) and baseband board light slogan (OptNo); In practical application, the mode that can adopt timesharing to send sends to each RRU under each light mouth with sequence data, supposes can connect M RRU under the light mouth of baseband board; Sequence data adopts N binary bits data (promptly detecting sequence length is N); Then get for the first time the sequence of M the bit of first bit composition in N the sequence data that mails to M RRU respectively and send, later and the like, up to being divided, N bit in N the sequence data all distribute for N time.Wherein, each M bit sequence that sends is corresponding one by one, as shown in Figure 4 with M RRU; Such as, BBU give RRU0 in the position of bit8 cocycle insert { Head, SlotNo; OptNo}, then give RRU1 in the position of bit9 cocycle insert identical sequence, other RRU.
Step S304, every grade of RRU postbacks the content of the relevant position of the actual sequence of receiving to BBU;
For example, every grade of RRU can return the sequence of the same format of sending with BBU to BBU, and for example, the M bit sequence is RRU from the value of the bit of the correspondence position of the M bit sequence that receives in the value of the bit of the position corresponding with RRU of this M bit sequence.For example; The subsequence of each 4 bits that send of BBU; First order RRU under the corresponding light mouth of first bit of this subsequence, then RRU obtains the detection sequence of this BBU to its transmission from first bit of this subsequence when receiving this subsequence; Return the subsequence of one 4 bit then to BBU, the value of first bit of this subsequence the bit value that to be RRU obtain from first bit of the subsequence that receives.
In embodiments of the present invention, after the RRU of upper level receives that BBU sends sequence data, give next stage RRU, and in this sequence data, find the content of corresponding own position and it is postbacked to BBU data forwarding.
Step S306, BBU detects the content of the sequence data that every grade of RRU postbacks;
BBU beams back the sequence of coming to every grade of RRU and carries out shift LD; After the content reception of the N that each RRU is postbacked a corresponding own position finishes, obtain the actual sequence data of receiving of RRU, the sequence data that again this sequence data and BBU is sent compares detection; If the sequence head of the sequence data that the sequence head of the actual sequence data of receiving of RRU and BBU send is inconsistent; Think that then mistake appears in the optical fiber of this RRU, this mistake does not belong to optical fiber and receives and dispatches azygous connection error, but other optical fiber mistake; For example, optical fiber has broken etc.If the sequence head of the actual sequence data of receiving of RRU is consistent with the sequence head of the sequence data that BBU sends; Content (being light mouth place baseband board slot number and baseband board light slogan) to the back detects again; If the content detection of back is inconsistent; Then think the optical fiber wrong of this RRU, at this moment, RRU corresponding detection result bit map is 1 (optical fiber wrong); If the content detection of back is consistent, it is correct to think that then optical fiber connects, and at this moment, RRU corresponding detection result bit map was 0 (optical fiber connects correct).
Step S308, BBU periodically scans testing result, and reports the warning information of optical fiber wrong according to testing result, and wherein, the information content comprises the light slogan of BBU and the id information of RRU;
In embodiments of the present invention, preferably, the light mouth following BBU that reports of warning information only reports the principle of an alarm down at most, that is: for the situation of multistage RRU optical fiber wrong under the same light mouth, BBU only reports from the nearest one-level RRU of light mouth.Such as; Two light mouths of BBU connect two-stage RRU respectively, if the optical fiber of the first order and second level RRU is connected equal mistake, BBU only reports the optical fiber wrong information of first order RRU; See also Fig. 5; As shown in Figure 5, when having only first order optical fiber to recover normal the connection, BBU just can report the optical fiber wrong information of second level RRU.
In the preferred embodiment of the present invention; BBU is scanning testing result, and on give the correct time, can adopt flow process as shown in Figure 6; As shown in Figure 6; BBU regularly scans the optical fiber joint detection result of every grade of RRU under each light mouth, and the result is added up, if the then count value increase of optical fiber wrong.
In a preferred implementation of the embodiment of the invention, as shown in Figure 7, can adopt the one-period cycle timer; The cycle of every interval 1s; Cycle timer carries out single pass to testing result, after the cycle timer circulation 5 times (being 5s), can travel through the count value of every grade of RRU optical fiber wrong under each light mouth; If it is correct that numerical value, thinks then that optical fiber connects less than 5 times; If count value is more than or equal to 5 times, promptly the scanning result of certain RRU be an optical fiber connection error continuous 5 times under certain light mouth, simultaneously, under the same light mouth of RRU on what RRU error count value all less than 5, then think optical fiber connection error.At this moment, BBU reports the warning information of optical fiber connection error.
In practical application, preferably, entire method can be divided into two major parts in the specific implementation: first is an optical fiber joint detection part; Second portion is a testing result information reporting part.Optical fiber joint detection part mainly comprises step S302-step S306, and testing result reports part to comprise step S308.
