Description
Technical field
The present invention relates to the data analysis technique of end side IP data and wireless signaling.
Background technology
Existing scheme is that wireless signaling separates with the crawl process of IP signaling, at present because the processing capability in real time of equipment and the processing scheme in later stage, present stage packet capturing technology can not realize that wireless signaling and IP signaling are simultaneously by a port crawl, can only adopt wireless signaling and the packet capturing of IP signaling independence, the later stage is carried out Conjoint Analysis to two packet capturing files.As shown in Figure 1, be wireless signaling and IP signaling collection schematic diagram on the mobile phone terminal.
Wireless signaling grasps by the signaling bag, be actually a signaling, it contains many wireless signalings, described many wireless signalings with time T tn be the time of base station, non-mobile phone local zone time, when software read a wireless signaling, handling procedure added a mobile phone local zone time T can for this piece wireless signaling; When the crawl IP signaling, the IP signaling that grasps grasps according to the mode of a signaling of a bag, and IP signaling itself does not comprise the time, and in the process of crawl, handling procedure can be given local zone time T of every IP signaling.
Because in the process of the data acquisition in early stage, two mutual incoherent times have been adopted: base station time and mobile phone local zone time, cause in the process of post analysis, can only adopt the method for manually time being estimated to analyze, the precision of analysis depends on whether base station and mobile phone terminal adopt identical time synchronized server, base station time server and mobile phone time server time difference and analyst's experience.
For example, the wireless signaling data are to export by piece, namely comprise many wireless signalings in a signaling piece, although every wireless signaling has independent time point, but the self-contained time of wireless signaling is the time according to the base station, because the time synchronized server of base station is not identical with the time synchronized server of mobile phone, with the mobile phone time deviation is arranged, even deviation is larger, affects the association analysis of wireless signaling data and IP data.As shown in Figure 2, be IP signaling and the wireless signaling software sectional drawing after the simultaneously crawl in packet capturing software.
As can be seen from Figure 2: wireless signaling is applied for Radio Resource at 11:40:20.342, discharges at 11:40:20.429, applies for beginning application at 11:44:31.500 next time, and 11:44:31.590 discharges; Corresponding on IP signaling, 11:44:23.681 begins to Packet Generation/receptions arranged between the 11:44:26.743 always, with normal flow chart can't be corresponding, cause analysis can't accurately confirm to eat dishes without rice or wine whether to have applied for or applied for failure.Experienced analyst can add in different acquisition time sections the time value of an estimation, can eliminate larger time difference in certain degree, but this mode can only be done qualitative analysis, can not do quantitative analysis.
