Fig. 6 is a flow chart of the main flow of the random access loading test according to the preferred embodiment of the present invention, and the specific implementation method steps of the preferred embodiment are shown in Fig. 6:

Step S602. The base station system configures the task of "random access loading test" according to the requirements. The parameters related to the task, such as the interval time of RA test, can be optional such as ms5120, ms10240, etc., and it is not recommended to be too short to avoid too frequent random access. Affecting business perception, there is also the total number of RA tests, which can be selected as n5, n10, n20, etc. The random access method is competitive, non-competitive, and random. There is another parameter that is required The number of terminals to be tested can be n10, n20, rand, etc., that is, the base station system selects the scale of the loading random access process, and the system directly selects the corresponding number of online terminals that can support this test for loading testing;

Step S604, the base station system initiates a measurement for the terminal supporting the RA load test according to the configured task (the MeasConfig related to "RA-Load-Test" is carried in the RRCConnection Reconfiguration message, including the RA test interval and the total number of RA tests);

Step S606, the terminal responds to the RRC ConnectionReconfiguration carrying the MeasConfig related to "RA-Load-Test". If the test is currently allowed to be initiated, the terminal responds to the RRC ConnectionReconfiguration Comeplete message, starts the measurement, monitors the Msg0PDCCH Order, and records the progress during this process at any time random access results;

Step S608, the base station system initiates a periodic PDCCH Order command to the terminal, (the total number of times and the periodic interval are configured in MeasConfig), the terminal records the situation of each random access, and sends a MeasurementReport message to the base station system after the measurement is completed Feedback the results of this random access loading test;

The signaling interaction process and random access process specifically involved in this preferred embodiment are shown in Figure 7. The random access process in Figure 7 is consistent with the current LTE protocol, and there is no change, so it does not need to be carried out in detail.

The system and method for the loading, testing and feedback of the LTE random access process disclosed in this preferred embodiment involves modification of network elements including base station systems and terminals, and at the protocol level, only one type of measurement is actually added on the RRC message interface With the corresponding measurement report, the capability field of the measurement is added to the supporting UE capability information, and other processes follow the definition of the current LTE standard protocol. Therefore, the changes are small and easy to deploy quickly.

Fig. 8 is a flow chart of a specific test process according to a preferred embodiment of the present invention. The technical solution of this preferred embodiment will be described in detail below in conjunction with specific embodiments, as shown in Fig. 8:

Step S802, the base station system manually configures a "random access loading test" task once, setting the RA test interval as ms10240, the number of RA tests as 10 times, the test terminal scale as 10 terminals, and the RA test only using the competitive access method;

Step S804, the base station system randomly selects 10 terminal users that support the stable state of this test and are not VoLTE among the online users according to the configured tasks, and initiates measurements to these 10 terminals (the type indicated in the RRC Connection Reconfiguration message is "RA- Load-Test" MeasConfig, and indicate that the RA test interval is ms10240, and the number of RA tests is 10 times);

Step S806: After receiving the terminal, it responds to the RRC Connection Reconfiguration Comeplete message, and starts recording random access every 10240 ms. (The business of the terminal is less affected);

Step S808 , the base station system will initiate 10 PDCCHOrder commands with an interval of 10240 ms each time for the 10 terminals, that is, a total of 100 RA test samples. During the test, the base station system will try to prevent these terminals from entering the IDLE state due to UserInactive;

Step S810, each time the terminal receives the PDCCH Order, it will perform a random access process, regardless of whether the random access is successful, it will record the result of the random access. (Recorded content such as "The final random access result after the third PDCCH Order is Success, including 2 Failure at Msg2, 1 Failure at MSG4 due to CT resolution in not passed, 1 Failure at MSG4 due to CT timer expired”);

Step S812, the terminal needs to judge "whether the random access is successful", whether "re-synchronize and maintain the RRC-CONNECTED state" in the source cell, if yes, go to step S814. If not, then enter step S816 step;

Step S814, the terminal feeds back a MeasurementReport message in the measured cell, carrying the test results related to "RA-Load-Test", including random access results and abnormal statistics after each PDCCH Order.

Step S816: If the terminal encounters random access failure or RLF during the test, the RRCConnectionReestablishmentRequest process is triggered, and the terminal ends the previous "RA-Load-Test" measurement, and feeds back the currently completed measurement through the RRCConnectionReestablishmentComplete message extension field. RA test-related MeasurementReport, the base station system can notify the test result of the measured cell through the X2 port specific message according to the source cell information after receiving it;

Step S818, step S814 and step S816 all go to this step, the base station system collects the reports fed back by these 10 terminals, conducts intelligent analysis, confirms the health of the random access area of the cell, and further guides the corresponding optimization work .

It needs to be added that after the measurement is initiated, if the UE needs to trigger a handover, such as A3 event handover, the terminal can terminate the "RA-Load-Test" measurement before the handover, and feedback the MeasurementReport related to the currently completed RA test in time , or the RRCConnectionReconfigurationComplete of the handover completion message can also be used to feed back the measurement report of the meta message through the extension field, which is not specifically stipulated in this document.
