Problems solved by technology

[0003] In the existing technology, test instruments are often used to verify the S1 interface interconnection between the core network and the base station. The test instrument has certain limitations. It can only test a single base station, and there are relatively few test users. When testing multiple base stations and multi-user scenarios, The method of adding a switch to the front end of the existing test instrument is often used for processing, but when this method is used, the processing of the test instrument is still to test the connected base stations one by one, which cannot meet the requirements of simultaneous testing of multiple base stations ; When testing multiple base stations and multi-user scenarios at the same time, only a large number of test instruments can be used to test at the same time. Because the current test instruments are very expensive, in order to meet the simultaneous test requirements of multiple base stations, it is necessary to purchase a large number of test instruments. It is very high and economically unacceptable; as LTE network deployment is in full swing, base station equipment is also deployed in large quantities at the same time, and the verification of the S1 interface between the base station and the core network is the top priority of the deployment work Heavy
[0004] Therefore, only existing test instruments cannot meet the simultaneous test requirements for large-capacity base stations, and it is urgent to develop a test device to meet the simultaneous test requirements for the S1 interface of large-capacity base stations, so as to optimize the entire LTE-scale experimental network and accelerate LTE.
