Description

Random access loading test method, device and system Technical field

The embodiments of the present invention relate to the field of communications, and in particular, to a test method, apparatus, and system for random access loading.

Background technique

In the Long Term Evolution (LTE) system, the application of the same-frequency networking is very common. Therefore, there are many problems on the same-frequency group network, such as the same-frequency interference caused by the same-frequency networking. For the physical random access channel (PRACH), the same-frequency interference and false alarm suppression may cause the system to detect the preamble (Preamble) sent by the cell edge user, resulting in possible random access failure or handover. The situation of failure, but for the base station system, this situation can not be identified. For the processing of Message 2 (Msg2, Random Access Response), Message 3 (Msg3, Contention Resolution) and Message 4 (Msg4, Complete of Contention resolution) in the random access process, there is a similar situation, or the information is asymmetric. of. That is, the information on the transmitting side and the receiving side is asymmetric.

FIG. 6 is a flowchart of a main process of a random access loading test according to a preferred embodiment of the present invention. The specific implementation method steps of the preferred embodiment are as shown in FIG. 6 :

Step S602: The base station system configures a “random access loading test” task according to requirements, and the task-related parameters, such as the interval time of the RA test, may be selected by ms5120, ms10240, etc., and are not recommended to be too short, so as to avoid excessive frequent random access. It affects the service perception and the total number of RA tests. It can be n5, n10, n20, etc. The random access mode is competitive, non-competitive and random. There are also three parameters. The number of terminals tested may be n10, n20, rand, etc., that is, the size of the random access procedure selected by the base station system, and the system directly selects a corresponding number of online terminals that can support the test for loading test;

Step S604: The base station system initiates measurement for the terminal that supports the RA loading test according to the configured task (the RRC Connection Reconfiguration message carries the “RA-Load-Test” related MeasConfig, including the RA test interval and the total number of RA tests);

Step S606: The terminal responds with an RRC Connection Reconfiguration carrying MeasConfig related to "RA-Load-Test". If the test is currently allowed to be initiated, the terminal responds to the RRC. Connection Reconfiguration Comeplete message, and start measurement, listen to Msg0PDCCH Order, and record the random access result in this process at any time;

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

The signaling interaction process and the random access procedure specifically involved in the preferred embodiment are shown in FIG. 7. The random access procedure in FIG. 7 is consistent with the current LTE protocol, and is not changed, and therefore does not need to be specifically implemented.

The system and method for loading, testing, and feeding back the LTE random access procedure disclosed in the preferred embodiment, the modified network element includes a base station system and a terminal, and at the protocol level, only one type of measurement is actually added to the RRC message interface. And the corresponding measurement report, the capability capability field of the measurement is added to the matching UE capability information, and other processes are defined by the current LTE standard protocol. Therefore, the changes are small and easy to deploy quickly.

FIG. 8 is a flowchart of a specific testing process according to a preferred embodiment of the present invention. The technical solution of the preferred embodiment will be described in detail below with reference to specific embodiments. Referring to FIG.

Step S802: The base station system manually configures a “random access loading test” task, and sets the RA test interval to ms10240, the number of RA tests to 10, the test terminal size to 10 terminals, and the RA test only uses the contention access mode;

Step S804: The base station system randomly selects 10 terminal users in the online user that support the stable state of the test and is not VoLTE according to the configured task, and initiates measurements to the 10 terminals (the indication type in the RRC Connection Reconfiguration message is RA- MeasConfig of Load-Test, and indicates that the RA test interval is ms10240 and the RA test frequency is 10 times);

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

Step S808: The base station system initiates 10 times for each of the 10 terminals. 10240ms PDCCH Order instruction, which is a sample of a total of 100 RA tests. During the test, the base station system will try to prevent these terminals from entering the IDLE state due to User Inactive.

Step S810: After receiving the PDCCH Order, the terminal performs a random access procedure every time, and the random access result is recorded regardless of whether the random access is successful. (The recorded content, for example, "The final random access result after the 3rd PDCCH Order is Success, which has 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 determine whether "random access is successful", whether the source cell "re-synchronizes to maintain the RRC-CONNECTED state", and if yes, proceeds to step S814. If no, go to step S816;

Step S814: The terminal feeds back the MeasurementReport message in the measured cell, and carries the test result related to “RA-Load-Test”, including the random access result and the abnormality statistics after each PDCCH Order.

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

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

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

With regard to the extension of the interface message, examples of messages involved in the preferred embodiment are as follows, but are not limited to this form:
