The process that the network test system of application present embodiment is tested is:
At first, base station monitoring equipment or Signaling Analyzer main frame and down link data testing equipment main frame are carried out time synchronized, and method for synchronous is: base station monitoring equipment or Signaling Analyzer main frame is direct-connected with down link data testing equipment main frame or set up network and be connected; Above-mentioned two main frames directly or by network connect biography temporal information mutually; Wherein a main frame is set to calibrate main frame, and another main frame is set to be calibrated main frame, and the described main frame that is calibrated is adjusted the system time of oneself according to the temporal information of the calibration main frame that receives.
This method for synchronizing time is respectively installed a utility program that is used for time synchronized on the Device Host of both sides, wherein the main frame of a certain side carries out same step calibration to another time of surveying on the main frame.Two side apparatus can carry out network by the socket port and connect, as long as just can carry out the work of equipment time synchronized when local area network (LAN) is arranged.Suppose to provide the standard time main frame to be called calibration main frame TS, the main frame that is calibrated is called TC, and set in advance the adjustment precision, then synchronous detailed process is referring to Fig. 5 its time, Fig. 5 be embodiment illustrated in fig. 3 in time synchronized flow chart between base station monitoring equipment or Signaling Analyzer main frame and down link data testing equipment main frame.This flow process may further comprise the steps:
Step 501 connects TS and TC by local area network (LAN), disposes the IP and the port of two equipment.This step and common computer are identical by the interconnected process of local area network (LAN), repeat no more here.
T=is from system time-TC system time/2 of TS reception
Whether step 506 judges T smaller or equal to the adjustment precision that sets in advance, if then notice calibration main frame time synchronized finishes, otherwise execution in step 507.
Be to preestablish the adjustment precision among Fig. 5, carry out time synchronized according to precision.In the practical application, can also set in advance update times or update times, step and Fig. 5 are basic identical, and difference is: step 506 is: judge whether to reach the update times that sets in advance, if then notice calibration main frame time synchronized finishes, otherwise execution in step 507.
Step 507 is: current machine system time+T, and record update times, and reinform TS and continue transmission time information, return step 504 then.
Than the method for existing manual setting device synchronization,, can realize that the both sides Device Host time is comparatively synchronously accurate by the equipment method for synchronizing time in the above present embodiment.Like this, before giving up-downgoing Conjoint Analysis device processes, the log data of two side softwares have just had identical time chi.
If the actual testing time is longer, after (such as several hrs), need carry out the synchronous checking work of main frame at regular intervals, simultaneous operation connects by Ethernet to be finished.If two main frames are step-out, then need the main frame time synchronous again.The process that synchronous checking also will be arranged behind the EOT.
The method of checking is very simple to be: the error amount that sets in advance a permission, TS sends this machine system time to TC, and TC compares time and this machine system time that receives, and calculates difference, if the absolute value of this difference thinks then that smaller or equal to the error amount that allows two equipment times are still synchronous; If the absolute value of this difference, is then thought two equipment times step-out greater than the error amount that allows.If under the situation of step-out, test does not also finish, and then carries out time synchronized again by process shown in Figure 5.
In addition, if two equipment are to connect transmission time information by local area network (LAN), can adopt and once set up the primary network connection synchronously, the back disconnects this connection synchronously, in order to avoid waste local area network (LAN) resource.
If before test the known two side apparatus times synchronous, also time of implementation synchronizing process not.
Then, base station monitoring equipment or Signaling Analyzer and down link data testing equipment are tested uplink data and down link data and gps data respectively, obtain uplink data and down link data and gps data respectively in real time and save as the log file.
Then, up-downgoing Conjoint Analysis equipment obtains up log file/descending log file and GPS file from above-mentioned two kinds of equipment respectively.
Then, up-downgoing Conjoint Analysis equipment earlier carries out format conversion with the data that obtain, be converted to uniform data format after, send to second data simultaneous module and carry out data synchronization processing, by both sides log file is carried out data synchronization processing, realize the combination of upstream data and gps data.In the prior art, upstream data and gps data not being carried out synchronously, below is example with upstream data and gps data synchronously, illustrates that second data simultaneous module of the up-downgoing Conjoint Analysis equipment in the present embodiment is carried out data synchronizing processing method.
Gps data and upstream data write down respectively, so there is not one-to-one relationship between the two, can only set up contact by certain time shaft.In general, the frequency of measuring the message appearance will be higher than the frequency of gps data, is time shaft so select the time in the up log file.
Idiographic flow is referring to Fig. 6, Fig. 6 be embodiment illustrated in fig. 4 in the data sync flow chart of second data simultaneous module;

Step 602 judges whether up log file and GPS file exist the crossing time period, if having then execution in step 603; Otherwise end data Synchronous Processing flow process.Here the time period of intersecting is represented with [Ts, Te].
Step 603, the time of getting article one data in the GPS file is set to Tg and Tg ', just Tg and Tg ' is initialized as the time of article one data of GPS file.
Step 604 reads data in the up log file, and writes down the temporal information Tm in these data.
Whether step 605 judges Tm smaller or equal to Ts, if then execution in step 606; Otherwise execution in step 607.
Step 606 sends to electric map module with the up-link information in these data or stores in the database again, returns step 604.
Whether step 607 judges Tg smaller or equal to Tm, if execution in step 608 then; Otherwise execution in step 610.
Step 608 sends to electric map module with the GPS information in the gps data or stores in the database.
Step 609 is given Tg ' with the Tg assignment, reads next the bar data in the GPS file, and the temporal information assignment in these data is given Tg, returns step 607.
Step 610 sends to electric map module with the GPS information in the most approaching corresponding gps data of Tg and Tg ' and Tm and the up-link information in the current uplink data or together stores in the database.
Whether step 611 judges Tm less than Te, if then return step 604; Otherwise data sync finishes.
The data sync of descending log file and GPS file also can adopt said process, no longer repeats here.
