In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and It is not used in the restriction present invention.
As shown in figure 1, a kind of Abis collection link affiliation methods for possessing error correcting capability, comprise the following steps:
Step 1:Signaling in link is acquired, and the signaling for collecting is decoded.Described link I.e. collecting device gathers the approach of signaling data, by TEI, IP, E1 and TS(Time slot)Carry out unique mark.
Step 2:Line link study is entered according to decoded signaling, and judges whether link is successfully learnt.Such as determine The link that signaling is located successfully is not learnt, then abandon the signaling.
Step 3:The signaling in cell and link that the link of learning success is belonged to sends and confirms cell and study Link pair, obtains the cell of link pair ownership.The link pair is up-link and downlink, and comprising a link pair mark Know.The link pair is designated the integer of 64, and high 32 is link home cell ID, and low 32 is TEI.The link To belong to cell by channel reqiure message authentications cell.When channel require message is received, such as Fruit message place link does not have home cell, then with regard to a newly-built cell, marked with the integer of random 32 for generating Know the cell.
Step 4:The link pair of link association output is detected, and judges whether link pair study is correct, it is such as correct Then direct output link pair, as incorrect, exits.Generally learn the time of all of link within 10 minutes, so in journey Sequence just can normally processing data after starting 10 minutes.
The ultimate principle of Abis collection link affiliation methods is to increase Abis associations by the cell of collection link ownership Accuracy.Collecting device gathers signaling data by gathering link, each a number of collection link of cell correspondence, and One collection link can only be subordinated to a cell, and in addition to the switching of minizone, all flow processs are occurred in same cell, So when signaling process association is carried out, can again increase returning for collection link that a signaling is located newly on the basis of in the past Category cell, can thus improve the success rate of association.Filtered out correctly from association results by way of link detecting simultaneously Link pair, it is to avoid the problem that cannot ensure to associate accuracy rate by standard agreement.
Specifically, when link association is carried out, if:Channel require places link is A, Immediately It is C, Channel activate ack (1) that assignment places link is B, Channel activate (1) place link Place link be D, Assignment command places link be D, Channel activate (2) place link be E, Channel activate ack (2) places link is F.Link association is concretely comprised the following steps:1st, channel require are received After message, a cell is created, identified with NEWCELL, while link A is belonged to into NEWCELL.2nd, Channel is received After activate (1) and Channel activate ack (1) message, link pair C+D is created, TEI is T2.3rd, receive After Immediately assignment, first associate with channel require, create link pair A+B, TEI is T1, due to A Belong to NEWCELL, link pair A+B is belonged to into NEWCELL, link pair mark Indentifier_ is generated by NEWCELL and T1 1;Then, Immediately assignment and Channel activate (1)/Channel activate ack are set up (1) association, because B belongs to NEWCELL, then link pair C+D is also belonged to NEWCELL, and by NEWCELL and T2 link is generated To being designated Indentifier_2.4th, Channel activate (2) and Channel activate ack (2) message are received Afterwards, link pair E+F is created, TEI is T3.5th, after receiving Assignment command message, Assignment is set up The association of command and Channel activate (2)/Channel activate ack (2), because D belongs to NEWCELL, Then E+F is belonged to into NEWCELL, link pair is generated by NEWCELL and T3 and is designated Indentifier_3.
By above-mentioned step, the study of the link of the flow process is completed, now, newly-built cell NEWCELL, the cell Comprising 3 link pairs:Indentifier_1+A+B, Indentifier_2+C+D and Indentifier_3+E+F.
As shown in figure 3, carrying out detection to link pair in the step 4 specifically includes following steps:
Step 401:Receives link pair, judges the study whether success of link pair mark, such as success and without link pair conflict if Send signaling to relating module and terminate;As unsuccessful, link conflict is judged whether.
Formal link pair is that correct link pair set is confirmed after link detecting.Link pair identifies sentencing for learning success Break and be:The link identification of the link pair for receiving has been contained in formal link pair.For example, the link pair for receiving Indenitfier_1+A+B, if containing link identification Indenitfier_1 in formal link pair, then be considered as chain Line learning success.The criterion of link pair conflict is:The link pair mark learning success of the link pair for receiving, but Link information in the link information of link pair and formal link pair is inconsistent, then be conflict.For example, the link pair for receiving Indenitfier_1+A+B, but be in the corresponding link pairs of formal link pair link mark Indenitfier_1 Indenitfier_1+C+D, then be judged as conflict.
The criterion of link conflict is:One link can only be subordinated to a link pair, if same link occurs In multiple links, then it is judged to conflict.For example, the link pair for receiving is Indenitfier_1+A+B, but in formal chain Centering link A in road belongs to another link pair Indentifier_2+A+C, and such case is considered as link conflict.
Step 402:Link pair is then cached without link conflict, and the number of times that link pair occurs is added up.
Step 403:Judge whether the number of times that link pair occurs is more than maximum statistics number.
Step 404:The number of times for meeting link pair appearance is more than maximum statistics number then link learning success, conflicts producing Link deleted.
Step 405:Link pair mark is set to into learning success, terminates link pair detection.
When link detecting is carried out, such as there is link pair conflict or there is link conflict, then directly terminate link pair detection.
Specifically, further link detecting can be explained by below step flow process:
A, receives link do not learn into Indenitfier_1+A+B because link pair identifies Indenitfier_1 Work(, and there is no link conflict yet, therefore caching link pair, will appear from number of times and plus 1.
B, receives link do not learn into Indenitfier_2+A+C because link pair identifies Indenitfier_2 Work(, and there is no link conflict yet, therefore caching link pair, will appear from number of times and plus 1.
C, receives link do not learn into Indenitfier_1+E+F because link pair identifies Indenitfier_1 Work(, and there is no link conflict yet, therefore caching link pair, will appear from number of times and plus 1.
D, continuous several times receive link pair Indenitfier_1+A+B, and link pair Indenitfier_1+A+B goes out occurrence Number thinks that Indenitfier_1+A+B is correct link pair more than maximum statistics number, and this link pair is saved in just In formula link pair, and link pair Indenitfier_2+A+C for conflicting therewith and Indenitfier_1+E+F are deleted from caching Remove.
There is chain to the Indenitfier_1+A+B in Indenitfier_1+D+F, with formal link pair in E, receives link Road is exited to conflict.
There is chain to the Indenitfier_1+A+B in Indenitfier_3+A+F, with formal link pair in F, receives link Road conflicts, and exits.
Based on above-mentioned Abis collection link affiliation methods, as shown in Fig. 2 the present invention also provides one kind possesses error correcting capability Abis collection link Home Systems, including signal collecting module 201, signaling decoding module 202, link study module 203, chain Road relating module 204 and link detection module 205.The signal collecting module 201 is acquired to the signaling in link, is adopted The packet of collection contains link information.The signaling that the signaling decoding module 202 is collected carries out decoding and decoded Signaling sends the link study module 203 to.203 pairs of signalings for receiving of the link study module judge, such as believe The collection link that order is located successfully is learnt, then chain is issued in the home cell by signaling together with the signaling place link Road relating module 204, otherwise, abandons the signaling, until signaling place link by till learning.The link association module 204 Link pair is confirmed and is learnt to the cell of link ownership, while the cell that the link pair obtained by association is belonged to is sent out Give the link detection module 205.The link detection module 205 is detected to link pair and is judged that link pair study is It is no correct.
The core concept of link detection module 205 is exactly:In the conflict of a pile link pair and the link pair set of link conflict In, the occurrence number of each conflict link pair is recorded, if certain link pair occurrence number reaches at first statistics number, then it is assumed that The link pair is correct, and the link pair is saved in formal link pair, and other link pairs for conflicting therewith are deleted.
Described to have Abis collection links Home System to include forwarding module 206, the forwarding module 206 is used for handle As a result it is sent to next module.
