Telecom terminal equipment that wants to access the public telecommunications network needs to apply for a network access license. The application for a "network access license" for communication products is commonly known as "CTA" in the industry. According to the current laws and regulations of our country, the state implements a network access licensing system for telecommunications terminal equipment, radio communication equipment and telecommunications equipment involved in inter-network interconnection used to access public telecommunications networks (China Mobile, China Unicom, China Telecom). Telecommunications equipment subject to the network access license system must obtain a network access license issued by the Ministry of Information Industry; without a network access license, it may not be connected to the public telecommunications network for use or sold domestically.
SRRC is the mandatory certification requirement of the State Radio Regulatory Commission, which is what we often call model approval. CTA is the mandatory requirement for communication products from the Telecommunications Equipment Administration of the Ministry of Industry and Information Technology. CTA needs to obtain an SRRC certificate before issuing a certificate. To put it simply, these two parallel lines eventually intersect.
Network license, the state implements a network access license system for telecommunications terminal equipment, radio communication equipment and telecommunications equipment involved in network interconnection used to access public telecommunications networks. Telecom equipment subject to the network access license system must obtain a network access license issued by the Ministry of Information Industry; without a network access license, it is not allowed to be connected to the public telecommunications network for use or sold domestically. The network access license certificate contains the certificate number, application unit, production enterprise, equipment name, equipment model, place of origin, remarks, certificate issuance date, and certificate limited date. Network access licenses are generally valid for 3 years.

(1) Telecommunications equipment network access license application form (formatted text provided by the Ministry of Information Industry). The application form shall be signed by the legal representative of the telecommunications equipment network access license applicant or his authorized agent and stamped with the official seal; when the applicant and the production enterprise are different legal persons, the application form shall also be signed by the legal representatives of both parties or their authorized agents. And the entrusted processing agreement stamped with the official seal. Overseas applicants should entrust an agency within China to submit the application form as the applicant and issue a letter of authorization.
(2) Enterprise legal person business license. Domestic applicants should provide the enterprise legal person business license.
