Mobile phone JATE certification test content and requirements

    China's mobile phone industry has developed rapidly in recent years and has become the world's largest mobile phone manufacturing base and important market. Now more and more mobile phones are exported to various countries, and the quality requirements of mobile phones in different countries are also different. Among them, mobile phone companies exporting to Japan should pay attention to Japan's certification requirements.

    Devices such as mobile phones that access public communication networks need to meet the certification and testing requirements of Japan's TELEC (according to Japan's Radio Law) and Japan's JATE certification (according to Japan's Ministerial Ordinance of MIC No.15 of 2004). Japan's Telecommunications Business Law was established in 1984. At that time, the Ministry of Public Administration, Internal Affairs, Posts and Telecommunications (MPHPT) authorized JATE as the only qualified agency to implement the qualified approval of the technical environment, so we used the name JATE to refer to the requirements of Japan's Telecommunications Business Law as JATE certification. In other words, JATE certification is to test whether the mobile phone meets the requirements of Japan's Telecommunications Business Law, and the corresponding TELEC certification is to test whether the mobile phone meets the requirements of Japan's Radio Law. Now Japan's Ministry of Public Administration, Internal Affairs, Posts and Telecommunications (MPHPT) has opened authorization and has authorized many agencies to conduct qualified approval of terminal equipment that meets the requirements of the Telecommunications Business Law. For example, other Japanese agencies can also review JATE certification reports and materials and issue approvals. However, due to custom, we still refer to the requirements of Japan's Telecommunications Business Act as JATE certification.

    Currently, the mobile phone models that can be used in Japan are: PHS, PDC, CDMA2000, and WCDMA. Among them, PHS is a technology developed in Japan, and China has also introduced it, which is the well-known Xiaolingtong. PDC is also a technology developed in Japan, and is currently mainly used in Japan. CDMA2000 and WCDMA are two of the familiar 3G technologies. Since Japan does not have a GSM network, GSM mobile phones cannot be used in Japan.

    The requirements for mobile terminal JATE certification are mainly protocol testing, which are as follows:

    1. Basic functions（Basic functions）
    2. Calling functions（Other calling functions）
    3. Transmission timing（Transmission timing）
    4. Random access control（Random access control）
    5. Time alignment control（Timing adjustment control）
    6. Location registration control（Location registration control）
    7. Function for complying with channel switching indication（Channel switching function）
    8. Functions for receiving level reports（Receiving level report function）
    9. Functions to comply with the direction to stop transmission（Function to comply with the command to stop transmission）
    10. Function automatically to suspend transmission when the receiving level has become degraded（Function to automatically terminate transmission when the receiving level has become degraded）
    11. Function automatically to suspend transmission（
    Function to ensure important communication） 12. Function to ensure important communication
