Beginning in 2013, Eastcom digitized the analog trunked system of Hohhot Public Security Bureau to transform all the original analog base stations into analog compatible base stations. It has constructed "Safe Capital" Project in 2016 in cooperation with the No.1 institute of Ministry of Public Security, and had built a total of 34 PDT digital trunked base stations, covering key areas and roads in the city, and equipped with more than 5000 PDT terminals. It has set up an exchange center in the communication room of Huhhot Public Security Bureau, realizing the interconnection with the existing PDT digital trunked system of district halls and allied cities, and realizing the "one network" of PDT in the whole district, and has set up network management, standard dispatching desk, GIS dispatching desk, whole network recording and other application business platforms in Municipal Bureau command center. At the same time, it realized the deep integration of PDT system and LTE broadband trunked system, the hybrid grouping and zero difference of broad band and narrow band terminal network through PSIP protocol. While guaranteeing low-latency voice communication, it also realized the interconnection of short message and GIS. PDT and LTE adopt uniform numbering rules to ensure user experience and improve operational efficiency.
