Device and method for consistency protocol verification of interfaces S1 of LTE (Long Term Evolution) wireless network

Abstract

The embodiment of the invention discloses a device and method for consistency protocol verification of interfaces S1 of an LTE (Long Term Evolution) wireless network. The device comprises an interface S1 module, an exchange module and at least two analog core network modules, wherein the interface S1 module is used for simultaneously receiving interface S1 test data sent by different base stations, determining the corresponding relationship between the different base stations and the analog core network modules through exchange processing, and transmitting the interface S1 test data from the different base stations to respective corresponding analog core network modules through the exchange module; and the analog core network modules are used for simultaneously processing the interface S1 test data which is received from the exchange module and comes from the different base stations, and transmitting a first response signal to the interface S1 module through the exchange module. The device and the method have the advantages that the consistency protocol verification on the interfaces S1 between multiple base stations and multiple analog core network modules can be simultaneously carried out, and the requirements of LTE for rapid network deployment are met.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a device and method for verifying consistency protocol of S1 interface of LTE wireless network. Background technique [0002] With the rapid development of mobile communications, the long-term evolution technology LTE (Long Term Evolution) is also developing rapidly. my country's LTE technology research, research and development and testing of related equipment are in the stage of large-scale experiments. In view of the urgent need for mixed networking of multiple core networks and multiple base station equipment in LTE network deployment, the first problem to be solved is to speed up the S1 interface interconnection verification between multiple core networks and multiple base stations.

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.
