fig. 1 shows an implementation flow of a data link performance testing method for a vertical industry according to a first embodiment of the present invention, and for convenience of description, only the relevant parts related to the embodiment of the present invention are shown, which is detailed as follows:
in step S101, when a preset service test trigger condition is satisfied, a service test module in the base station generates service test data, where the service test data includes a service test address, and the service test address includes addresses of a UPF network element and a MEC network element.
The embodiment of the invention is suitable for testing the performance of a data link, in particular to the performance of the data link from a base station to a UPF (User Plane Function) network element and an MEC (Mobile Edge Computing) network element, wherein the base station comprises a service testing module which supports a service test which can be configured at regular time, in the specific implementation, the service testing module can be used for configuring the type of the service test, the duration of the service test, the network element address corresponding to the service test and other related information, the type of the service test can comprise ping test, udp test and/or tcp test and the like, the service testing address comprises the address of the UPF network element and the address of the MEC network element, the service testing address at least comprises the address of one UPF network element, and the service testing address can be the addresses of all the UPF network element and the MEC network element which are communicated with the base station.
Preferably, before a service test module in the base station generates service test data, configuring a trigger type of a service test, where the trigger type includes periodic trigger, event trigger, or combined trigger of the periodic trigger and the event trigger, configuration information of the periodic trigger includes a test period and a first service test duration, configuration information of the event trigger includes a trigger event and a second service test duration, and the trigger event includes acquiring an address of a new UPF network element and/or receiving a service test request triggered by a user based on the configured address of the UPF network element or the MEC network element, thereby improving flexibility of service test configuration. The first service test duration refers to the duration of each service test executed according to the test cycle; the second service test duration refers to the duration of each service test executed when the service test is executed according to the trigger event; the duration of the first service test is the same as or different from the duration of the second service test. For example, the triggering type of the service test is periodic triggering, the period of the service test is set to be 15 minutes, and the duration of each service test execution is 90 seconds; for another example, the trigger type of the service test is event-type trigger, the trigger event of the service test is set to obtain the address of the new UPF network element, and the duration of executing the service test each time is 60 seconds.

The method of claim 1, wherein after the step of generating the service test result for reflecting the performance of the data link from the base station to the UPF network element and from the base station to the MEC network element according to the decapsulated service test feedback data, the base station further comprises:
and the base station compares the service test result with the previous service test result, and if the comparison result is greater than a preset difference threshold, alarm information is generated.
8. A data link performance test system facing vertical industry comprises a base station, a UPF network element and an MEC network element, and is characterized in that the base station comprises a service test module, wherein,
the service test module is used for generating service test data, the service test data comprises a service test address, the service test address comprises an address of a UPF network element and an address of an MEC network element, and the service test address at least comprises an address of a UPF network element;
the base station is used for sending packaged service test data to the UPF network element based on the service test address and receiving packaged service test feedback data returned by the UPF network element, wherein the service test feedback data comprises the service test feedback data of the UPF network element and the MEC network element; and the base station is also used for generating a service test result for reflecting the performance of the data link from the base station to the UPF network element and from the base station to the MEC network element according to the service test feedback data after the decapsulation.
9. The data link performance testing system of claim 8, wherein said base station and said UPF network element interact said encapsulated traffic test data and said encapsulated traffic test feedback data based on a fixed tunnel endpoint identification.
10. The data link performance testing system of claim 8, wherein the base station and the UPF network element encapsulate the traffic test data and the traffic test feedback data, respectively, in the form of GTP encapsulation.
