Summary. Radio Resource Management (RRM) is a system check associated with single channel interference and other radio transmission features in Long Term Evolution (LTE) systems. And Testing of Test Control Notation (TTCN-3) is an excellent, internationally standardized abstract programming language for developing tests. Its abstraction, scalability and standardization with respect to interfaces make TTCN-3 the best choice for implementing the RRM test suite. An excellent and important element in test systems, the precision codec encodes TTCN-3 values according to the encoding rule into one bit sequence for you, and decodes another bit sequence according to the decoding assumption. There are actually 13 types of message type definitions and seven additional coding rules in the rrm compliance testing framework, so developers need to configure multiple codecs according to pVarious coding guidelines. This article focuses on a well-known method of programming the required codecs using the RRM test suite. First, only the meaning of the codecs in the TTCN-3 test systems is explained, then the TTCN-3 control interface is described in detail, and finally the implementation of all codecs for specific type definitions is shown. In the RRM compliance testing system.

Radio Resource Management (RRM) is system-level management of single channel interference and other radio transmission properties associated with Long Term Evolution (LTE) systems. And Checks Test Control Notation (TTCN-3) is an abstract programming language standardized by Mondial for test actions. Abstraction, to scaleThe capacity and standardization of the user interface make TTCN-3 the best choice for this implementation of the RRM test suite. As a highly recommended module on systems, the codec test encodes TTCN-3 values … Expand

How many times protocol compliance testing has become something common. During development, the TD_LTE radio tester type must be configured according to the protocol specifications. Special programming languages such as TTCN-3 and tools are available for this. This document creates a conformance test product based on the TTCN-3 standard test notation and details the conformance testing process.
TTCN-3 can be an abstract language for defining abstract test suites. Encoding TTCN-3 Variables in the sense of physically transmitted messages and decoding many strings in their representation Ttcn-3 is an external specialized component called CoDec. CoDec development must be explicitly or implicitly included in any ttcn-3 testing activity. Experience has shown that the development and maintenance of CoDec is associated with high costs. This article introduces mea methodological approach to simplifying CoDec development. The approach has also been designed to help you. This allows developers to complete the codec by simply creating an XML file. It currently only helps a few types of logs, it provides a structure that can be extended to allow them to support more and more log history formats.
