Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of Abis that possesses error correcting capability gathers link affiliation method, comprises the following steps:
Step 1: the signaling in link is gathered, and the signaling collecting is decoded.Described link is the approach that collecting device gathers signaling data, by TEI, IP, E1 and TS(time slot) carry out unique identification.
Step 2: carry out link study according to decoded signaling, and judge whether link is successfully learnt.As the link that determines signaling place successfully do not learnt, abandon this signaling.
Step 3: the community that the link of learning success is belonged to and the signaling in link send and confirm community and study link pair, obtain the community of link to ownership.Described link is to being up link and down link, and comprises a link to sign.Described link is to being designated the integer of 64, and high 32 is link home cell ID, and low 32 is TEI.Described link is the community by channel reqiure message authentication to the community of ownership.When receiving channel require message, if message place link does not have home cell, so with regard to newly-built Yi Ge community, with a random integer of 32 generating, identify this community.
Step 4: the link of link association output, to detecting, and is judged to whether link is correct to study, as correct direct output link pair, exit as incorrect.Conventionally the time of all link of study in 10 minutes, so after program starts 10 minutes deal with data normally just.
The basic principle that Abis gathers link affiliation method is by the community that gathers link ownership, to increase the accuracy of Abis association.Collecting device gathers signaling data by gathering link, the collection link of the corresponding some in each community, and one gather link and can only be subordinated to Yi Ge community, except the switching of minizone, all flow processs are all to occur in same community, so when carrying out signaling process association, increase again the home cell that a signaling place gathers link on basis that can be former newly, so just can improve associated success rate.Mode by link detecting filters out correct link pair from association results simultaneously, has avoided cannot guaranteeing by standard agreement the problem of associated accuracy rate.
Particularly, when carrying out link association, establish: Channel require place link is that A, Immediately assignment place link are that B, Channel activate (1) place link are that C, Channel activate ack (1) place link are that D, Assignment command place link are that D, Channel activate (2) place link are that E, Channel activate ack (2) place link are F.The concrete steps of link association are: 1, receive after channel require message, create Yi Ge community, by NEWCELL sign, link A is belonged to NEWCELL simultaneously.2, receive after Channel activate (1) and Channel activate ack (1) message, create a link to C+D, TEI is T2.3, receive after Immediately assignment, first associated with channel require, create link to A+B, TEI is T1, because A belongs to NEWCELL, link is belonged to NEWCELL to A+B, by NEWCELL and T1 link generation to sign Indentifier_1; Then, set up the associated of Immediately assignment and Channel activate (1)/Channel activate ack (1), because B belongs to NEWCELL, link is also belonged to NEWCELL to C+D, by NEWCELL and T2 link generation to being designated Indentifier_2.4, receive after Channel activate (2) and Channel activate ack (2) message, create a link to E+F, TEI is T3.5, receive after Assignment command message, set up the associated of Assignment command and Channel activate (2)/Channel activate ack (2), because D belongs to NEWCELL, E+F is belonged to NEWCELL, by NEWCELL and T3 link generation to being designated Indentifier_3.
By above-mentioned step, the link of this flow process has been learnt, and now, NEWCELL ，Gai community, newly-built Liao Yige community comprises 3 link pair: Indentifier_1+A+B, Indentifier_2+C+D and Indentifier_3+E+F.
As shown in Figure 3, in described step 4, link is comprised the following steps detecting specifically:
Step 401: receiver pair, judge that whether link is successful to sign study, as success and without link, conflict is sent signaling to relating module and finished; As unsuccessful, judge whether to exist link conflict.
Formal link to for confirming correct link pair set after link detecting.Link is judged as sign learning success: formal link centering, comprised the right link identification of link receiving.For example, the link receiving is to Indenitfier_1+A+B, if comprised link identification Indenitfier_1 formal link centering, so just thinks link identification learning success.Link to the criterion of conflict is: the right link of the link that receives is to sign learning success, but the link information of the right link information of link and formal link centering is inconsistent, is conflict.For example, the link receiving is to Indenitfier_1+A+B, but at link corresponding to formal link centering chain line Indenitfier_1 to being Indenitfier_1+C+D, be judged as conflict.
The criterion of link conflict is: a link can only be subordinated to a link pair, if same link appears in a plurality of links, is judged to be conflict.For example, the link receiving is to for Indenitfier_1+A+B, but belongs to another link to Indentifier_2+A+C at formal link centering link A, and this situation is just thought link conflict.
Step 402: without the link buffer memory link pair that conflicts, and link is added up to the number of times occurring.
Step 403: judge whether link is greater than maximum statistics number to the number of times occurring.
Step 404: meet link the number of times occurring is greater than to link learning success of maximum statistics number, the link that produces conflict is deleted.
Step 405: link is made as to learning success to sign, finishes link to detecting.
When carrying out link detecting, as there is link to conflict or have link conflict, directly finishing link to detecting.
Particularly, can further link detecting be made an explanation by following steps flow chart:
A, receiver, to Indenitfier_1+A+B, because link does not have learning success to sign Indenitfier_1, and do not have link conflict, therefore buffer memory link pair adds 1 by occurrence number yet.
B, receiver, to Indenitfier_2+A+C, because link does not have learning success to sign Indenitfier_2, and do not have link conflict, therefore buffer memory link pair adds 1 by occurrence number yet.
C, receiver, to Indenitfier_1+E+F, because link does not have learning success to sign Indenitfier_1, and do not have link conflict, therefore buffer memory link pair adds 1 by occurrence number yet.
D, continuous several times receive link to Indenitfier_1+A+B, link is greater than maximum statistics number to Indenitfier_1+A+B occurrence number, therefore think that Indenitfier_1+A+B is correct link pair, by this link to being saved in formal link centering, and by with it conflict link Indenitfier_2+A+C and Indenitfier_1+E+F are deleted from buffer memory.
To Indenitfier_1+D+F, there is link to conflicting with the Indenitfier_1+A+B of formal link centering in E, receiver, exits.
To Indenitfier_3+A+F, there is link with the Indenitfier_1+A+B of formal link centering and conflict in F, receiver, exits.
Abis based on above-mentioned gathers link affiliation method, as shown in Figure 2, the present invention also provides a kind of Abis that possesses error correcting capability to gather link Home System, comprises signal collecting module 201, signaling decoding module 202, link study module 203, link association module 204 and link detecting module 205.Signaling in 201 pairs of links of described signal collecting module gathers, and the packets of information gathering contains link information.Described signaling decoding module 202 is decoded the signaling collecting decoded signaling is sent to described link study module 203.203 pairs of signalings that receive of described link study module judge, as the collection link at signaling place is successfully learnt, signaling is issued to link association module 204 together with the home cell of this signaling place link, otherwise, abandon this signaling, until signaling place link is learnt.The community of 204 pairs of link ownership of described link association module is confirmed and is learnt link pair, the link obtaining sent to described link detecting module 205 to belonged to community simultaneously by association.205 pairs of links of described link detecting module are to detecting and judging whether link is correct to study.
The core concept of link detecting module 205 is exactly: in link pair set conflict and link being conflicted at a pile link, record the right occurrence number of each conflict link, if certain link reaches statistics number at first to occurrence number, think that this link is to being correct, by this link, to being saved in formal link centering, and the link that other are conflicted is with it to deleting.
The described Abis of having gathers link Home System can also comprise forwarding module 206, and described forwarding module 206 is for sending to result next module.
Adopt Abis of the present invention to gather link affiliation method for wireless network perspective project, except having improved significantly the associated rate of ABIS interface, also successfully collected carrier frequency corresponding to community, frequency and adjacent area frequency message, by contrasting with the network profile of office side, the chain circuit message of collecting, carrier frequency, frequency and frequency drawn game side, adjacent area are consistent.
