June 15. According to the relevant information released by Beijing University of Posts and Telecommunications, the admission notice of doctoral students from the School of Cyberspace Security of Beijing University of Posts and Telecommunications was issued on June 15. Compared with the master's degree, the admission of doctoral students is a very complicated and long process, which requires doctoral students to complete various audits themselves, so the admission notice of doctoral students is late. Beijing University of Posts and Telecommunications is the first post and telecommunications institution of higher learning in New China. It is a national key university directly under the Ministry of Education, which is the key construction of the Ministry of Industry and Information Technology. It is a research university with information technology as its feature and engineering as its main body, and it is an important information technology talent training base in China.
