Description

LTE signalings shunt method and system
Technical field
The present invention relates to mobile communication signaling dividing technology field, more particularly to a kind of LTE signalings shunt method and system.
Background technology
The access means such as Mobile Network Signaling is accessed by high-ohmic cross-connection, mirror image, light splitting access, are bypassed simultaneously from signaling network It is accurate to replicate the signaling data transmitted on signaling link.Signalling link load, Internet usage, industry are analyzed by signaling data Be engaged in signaling process, operation exchange result, be signaling network management and maintenance, quality of service monitoring and analysis provide efficiently and When supporting method, and then for mobile network operation stability and security provide safeguard.
After it have passed through the convergence of more plurality of devices, every optical fiber of the signaling traffic being transferred on collecting device is all There are a data of multiple network elements, the data of each network element may also be on multiple optical fiber, and when being associated again a use Multiple interface data at family, such as s1, s11, s6a, sgs data are put into an equipment to handle.The user of one province is several at least Million, at most several ten million, and the process performance of an equipment is limited.How these subscriber signaling data completely to be divided Stream, it is a problem of signaling process field.
Traditional LTE signaling shunt methods are to carry out simple process to signaling by prime equipment, by the key in signaling Information is exported to a rear class equipment with custom field, is associated and synthesized and business processing by rear class equipment, then generated Various types of tickets and business.But with the fast development of LTE network, the swift and violent increase of signaling traffic.Conventional architectures by The limitation of the process performance and device memory of rear class equipment, even if the custom field of prime output have passed through optimization, rear class connects The data of receipts have also exceeded the process performance of an equipment, limit the disposal ability of acquisition system, it is impossible to meet present make Use demand.
That is, in the case where existing signaling shunts framework, it is existing in the case where the custom field that prime goes out is fixed Signaling acquisition system bottleneck is the disposal ability of rear class equipment.And the epoch of LTE flows outburst are in now, daily signaling Total flow is all increasing, and this not expansible framework will soon not tackle flow at this stage, causes the loss of data, Influence the use of data.
The content of the invention
It is contemplated that at least solves one of above-mentioned technical problem.
Therefore, it is an object of the present invention to propose a kind of LTE signalings shunt method, this method is not influenceing signaling use On the basis of the association of family, flow is shunted, improves treatment effeciency, has saved cost, while facilitates the expansion of flow Hold, disclosure satisfy that the use demand of big flow.
It is another object of the present invention to propose a kind of LTE signalings separate system.

Flow issues module, for signaling traffic to be issued according to mme network elements, to the mme group of each mme network elements Id and mme code id are issued, so that every association is set by XOR algorithm calculation value further according to associate device number modulus Standby load tends to be balanced, and the signaling data of processing approaches.
6. LTE signalings separate system according to claim 5, it is characterised in that the interface comprise at least s1 interfaces, S11 interfaces, s6a interfaces and sgs interfaces, the signaling decoding module are used for:
S1 interfaces, s11 interfaces, s6a interfaces and sgs interfaces are decoded according to respective agreement, with extract respectively s1 interfaces, Key message in s11 interfaces, s6a interfaces and sgs interfaces.
7. LTE signalings separate system according to claim 6, it is characterised in that the network element study module is used for:
By the crucial signaling in s1 interfaces, mme group id and mme the code id values of mme network elements are obtained, use mme Two kinds of group id, mme code id and s1_mme_ip key build table, and by mme group id, mme code id and s1_ In mme_ip deposit mme tables, the mme tables can be inquired by mme group id, mme code id or s1_mme_ip, made It is that key establishes carrying table with the carrying information carried in the crucial signaling in s1 interfaces, and s1_mme_ip is stored in the carrying In table;
When equipment receives the crucial signaling carried in s11 interfaces, carrying is inquired about using the carrying information in s11 key signalings Table, if finding carrying table, s1_mme_ip is taken out from the carrying table, and the use of s1_mme_ip is that key inquires about mme tables, And in the mme tables for finding the s11_mme_ip deposits of the s11 interfaces after finding;
The use of the authentication information carried in the crucial signaling in s6a interfaces is that key establishes authentication table, s6a_mme_ip is stored in and reflected To weigh in table, the authentication information carried using the crucial signaling in s1 interfaces inquires about the authentication table for key, and in success of tabling look-up When, judge that two datas are the data in a mme network element, and s6a_mme_ip is taken out from authentication table, believed using s1 The s1_mme_ip inquiry mme tables of order, and in the mme tables for finding s6a_mme_ip deposits after finding;
The use of the mme group id and mme code id in the crucial signaling in sgs interfaces is that key inquires about mme tables, when finding During mme tables, in the mme tables that the sgs_mme_ip deposits of sgs signalings are found.
8. LTE signalings separate system according to claim 7, it is characterised in that the flow issues module and is used for:
XOR Hash is carried out according to the mme group id of each mme network elements and mme code id, to determine that the mme network elements will Fiber port corresponding to the associate device issued, and ip of the mme network elements in each interface is filtered by ip rules, issue To corresponding fiber port, a mme network element is completely issued to same associate device.
