移动通信网络下的授时技术

With the development of mobile communicationnetwork, various services of network require the time precision among the network nodes more and more strict. However, the current standards cannot satisfy those requirements, even though they have some time synchronization methods and wireless signals with time information. Meanwhile, in the field of time synchronization, the time synchronization protocols and reasearches about the mobile communication network has not been discussed. So this paper researches the technology of time synchronization under the circumstances of mobile communication network in order to satisfy the time precision requirements in new application scenarios, such as vehicle network, Internet of Things.
