数字集群的运营模式探讨

专业移动通信网要想获得发展,首先要对专业移动通信网与公众移动通信网的区别有准确的认识,其次要有统一的数字集群系统,第三要有较好的实际运营模式.专业移动通信的建网模式有小型专网、大型专业共网、大型运营共网和公众移动通信网运营按下通话(PTT)业务等4种.数字集群共网的运营模式有民营型、国营型、先国有后民营型和国有民营型等4种.中国现阶段以采用国有民营型为宜,并要为其制订发展政策.

Discussion on Operation Modes of Digital Trunking Systems

For the development of private mobile communication networks, the differences between the private mobile communication network and the public mobile communication network should be exactly understood first. Besides, it requires a unified digital trunking system and a feasible operating mode. The networking modes of private mobile communication include the Private Mobile Radio (PMR), Public Access Mobile Radio (PAMR), commercial operational PAMR and the Push-To-Talk (PTT) service of public mobile communication networks. The operation modes of common digital trunking networks can be private-run, state-run, from-state-to-private-owned and state-owned private-run. It is currently fit for China to adopt the state-owned private-run mode and make relevant development policies.
