General-purpose interoperability test system and test method thereof

Abstract

The invention discloses a general-purpose interoperability test system and a test method thereof. The system comprises a main test control and protocol stack management platform, a general-purpose underlying simulation instrument and an antenna transmission module, wherein the main test control and protocol stack management platform comprises a general-purpose main test control module and a protocol stack substitution and adaptation module, the general-purpose underlying simulation instrument is used for carrying out the function of the physical layer and the switching between baseband signals and radio frequency signals, and the antenna transmission module is used for transmitting radio frequency signals and receiving radio frequency signals coming from a tested terminal. Based on the invention, the interoperability test on different network devices and terminals can be simulated as long as the protocol stacks in different network devices are changed, as a result, the network side hardware devices of different manufacturers do not need to be purchased any more, but each network device manufacturer provides a corresponding protocol stack, consequently, the interoperability test cost can be greatly decreased, and the difficulty in implementing the interoperability test can be reduced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a general interoperability test (IOT, Inter-Operability Test) system and a test method thereof. Background technique [0002] The field of mobile communication has the following characteristics: [0003] 1. The equipment in mobile communication includes network equipment and terminal equipment, which are produced and developed by thousands of different enterprises at home and abroad; [0004] 2. Mobile communication needs to ensure the interconnection between network equipment and terminal equipment produced by different manufacturers. [0005] In order to ensure the interoperability of communications worldwide, several global international standardization organizations have been established in the field of communications, responsible for formulating corresponding specifications and agreements, and requiring all communication-related enterprises to follow the requirements of th...

AI Technical Summary

Problems solved by technology

[0008] 1. There are many manufacturers of network equipment. If the terminal needs to perform interoperability tests with network equipment produced by different manufacturers, it is necessary to purchase corresponding network equipment from all manufacturers, which is extremely costly and occupies a large area

[0009] 2. Different network devices have different architectures and internal implementations, and they involve intellectual property issues of each company, which are not disclosed to the public. Testers cannot understand their internal implementations and locate problems in testing

[0010] 3. For different network devices, different test scripts need to be written separately, which is a heavy workload and repetitive work
