Description of drawings:
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute qualification of the present invention.In the accompanying drawings:
The association algorithm of Fig. 1 IU-PS interface key-course data and bearing bed data
Embodiment:
For making the object of the invention, technical scheme and advantage clearer, specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as to qualification of the present invention.
The association algorithm of IU-PS interface key-course data and bearing bed data is as shown in Figure 1: program receives after the data flow of IU-PS interface, and with key-course data RANAP data, and bearing bed data GTP protocol data is separated.
The RANAP data extract the OPC of M3UA layer, DPC; Source Local Reference (SLR) and Destination Local Reference (DLR) with the SCCP layer; Wherein identical (OPC, DPC, SLR; DLR) PMM of sign connects, and the key-course plane signaling of setting up between sign mobile phone and the SGSN is connected.
The GTP protocol data extracts Client IP, GTP-TEI, and it is, wherein identical that (Client IP GTP-TEI) is designated a GTP and connects, and the bearing bed data of setting up between sign mobile phone and the SGSN are connected.
Program is extracted Activate PDP from PMM connects; RAB-Assignment, message such as Deactivate PDP extract Client IP from Activate PDP Accept message; From RAB Assignment message, extract GTP-TEI, as the critical field among the PDP Session.
Program is isolated user's conversation procedure, mainly according to five-tuple information in the communication process from a GTP connects; I.e. (Source IP, Destination IP, Source Port; Destination Port Proto) does separation, and the packet of identical five-tuple is a GTP Session.
In the association algorithm of IU-PS interface key-course data and bearing bed data, program is taken out GTP Session in order, does comparison with PDP Session then, and concrete algorithm expression formula is as follows:
IF（GTP_Session.ClientIP?=?PDP_Session.ClientIP?AND?GTP_Session.?GTP-TEI?=?PDP_Session.GTP-TEI）?THEN
PDP_Session.Ptr?=?GTP_Session
The implication of this algorithm expression formula is following: if the mobile phone IP address that GTP Session comprises is identical with the mobile phone IP address that PDP Session comprises; And GTP Session comprises GTP-TEI and PDP Session, and to comprise GTP-TEI identical; Represent that then this GTP conversation procedure belongs to this PDP process; Then in PDP Session, make marks, with Ptr pointed GTP Session, follow-up qualified GTP Session then adopts the mode of chained list to be inserted into after the previous GTP Session.
Behind the association algorithm through IU-PS interface key-course data and bearing bed data; Through PDP Session; Program just can find all GTP conversation procedures that are associated with this PDP activation; Can make things convenient for the network optimization personnel to trace back to the GTP conversation procedure like this, improve the efficient of service optimization greatly by PDP activation.
Should be understood that above-mentioned description to specific embodiment is comparatively detailed, can not therefore think the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with accompanying claims.
