Docomo Certification

NTT Docomo was spun off from Nippon Telegraph and Telephone Corporation (NTT) in August 1991. NTT Docomo is the largest mobile carrier in Japan, with over 51.4 million users. It offers a range of cutting-edge mobile multimedia services.


Japanese operator NTT Docomo test certification

In order to protect the wireless network and control the waste of network resources, operators in all countries have their own unique operator test certification, which is a common practice.

Japan is no exception. NTT docomo, the largest telecom operator in Japan, has formulated the test contents of RF, DST signaling, DFTG, performance, etc. to make the terminal equipment meet their access requirements.

Especially in the Internet of Things era, a large number of terminal devices need to be connected to operators. When the communication is concentrated, congestion will occur, which will aggravate the operating burden of operators, resulting in other devices being disconnected from the network.

Example of completed NTT docomo certificate

NTT docomo operator testing and certification process is as follows:

     1. Deeplight assists in submitting the application for operator certification.

     2. Both parties confirm and sign the NDA agreement.

     3. Confirm the detailed specifications of the products, and give priority to the use of certified modules.

     4. List test case according to product specifications.

     5. Test-rectify-retest the test list until the test is completed.

     6. Submit the test report to determine whether it is ok.
According to the product form, the contents of NTD docomo operator test are different, and the common test contents are as follows:

1. docomo DST test, which tests whether the tested equipment meets docomo‘s protocol specification. Note: This test needs to avoid the interference of the existing network.

2. DRFL test, the initial stage of capability test, checks whether the information declared by the equipment through signaling matches the information declared by the manufacturer.

3. DST test, this test needs to run docomo script to check the protocol compliance in different scenarios.

4. Performance test, through product specifications, confirm the verification of actual functions such as telephone dialing, data throughput, network injection and network disconnection, and VoLTE.
