    • Abstract ( 175 )   
    • The core issue ofFRANDprinciple is to provide fair, reasonable and non-discriminatory licensing fees. In this type of cases, the commonly used methods are comparable licensing agreement, Top-down and Bottom-up, etc. In some complex cases, several methods need to be combined to analyze. Because the conclusion of comparable licensing agreement is signed voluntarily by both parties, conforms to the principle of marketization, has the similarity of licensing environment, and is easy to operate, it often becomes the preferred method for judges. Based on the analysis of cases of Huawei and UP, Ericsson and TCL, this paper analyses the connotation of comparable licensing agreement method. It also provides some reference for enterprises to sign corresponding licensing agreements or how to screen suitable licensing agreements in licensing fee disputes.

    • Research on international competitive situation of quantum communication based on patent analysis
    • ZHANG Qian
    • Information and Communications Technology and Policy. 2019, 45(10): 10-13.
    • Abstract ( 170 )   
    • As a theoretically absolutely secure information transmission technology, quantum communication has received extensive attention from the global industry. In recent years, it has gradually moved from theory to practice,commercialization and industrialization.The United States, Japan, China, and Europe are among the top of the world in basic research and applied technology.The number of patents has grown rapidly.The number of applications in the early years of the United States and Japan were high. But in recent years, more and more patent applications have come from the Chinese. The
      number of QKD patents is greater than the number of QT/QSS/QSDC patents. Because the application deployment of CV-QKDtechnology is less difficult thanDV-QKD,the CV-QKDpatent applications are more active. American innovation companies actively apply for patent applications and launch projects. Domestic research institutes, companies, and equipment manufacturers are actively conducting research on quantum communication.And the QKD-based quantum secure communication protocol, network and devices are themaindirection of patent innovation.

    • Using system dynamics to analyze the mechanism of big data regulation
    • LIU Yang
    • Information and Communications Technology and Policy. 2019, 45(10): 76-81.
    • Abstract ( 128 )   
    • Big data is an imperative foundation of modern life and it has already been widely used all over the world. However, the abuse of big data is becoming more and more serious. This study develops a system dynamics model to analyze the mechanism of big data regulation. And the model is verified in an anti telecom and network fraud system.The findings indicate that user self regulation is the symptomatic solution and system regulation is the fundamental solution to the regulation problem. System coverage has positive indirect effects to solving the regulation problem, while behavior variation and switching cost have negative indirect effects at the same time. The study validates an innovative approach in the combination of system dynamics and big data regulation, and finds an effective way to analyze the mechanism of big data regulation.
