Network switchover method and system based on TD-LTE internet protocol camera

Abstract

The invention relates to a network switchover method and system based on a TD-LTE internet protocol camera. The network switchover method comprises the steps that the TD-LTE internet protocol camera selects a default network after being started; the TD-LTE internet protocol camera detects the state of the network in real time, extracts and uses the delay tau and the packet loss probability upsilon when the default network carries out video transmission, preprocesses the delay tau and the packet loss probability upsilon and calculates the network quality (please see the formula in the specification), wherein Qos is the network quality, and a is a preset user preference value; whether the Qos of the default network is smaller than a preset threshold value is judged, if yes, the TD-LTE internet protocol camera is automatically switched to a standby network, and if not, the TD-LTE internet protocol camera continues working under the default network. According to the network switchover method and system based on the TD-LTE internet protocol camera, the default network is selected according to the preference of the user, and the TD-LTE internet protocol camera selects the default network after being started, and detects the network state in real time. As the TD-LTE internet protocol camera intelligently selects the network according to an analysis value, the convenience of deploying the TD-LTE internet protocol camera on various occasions is largely improved.

Description

technical field [0001] The present invention relates to the field of network switching, more specifically, to a network switching method and system based on a TD-LTE network camera. Background technique [0002] With the development of wireless network technology, the wireless transmission bandwidth is gradually increasing. TD-LTE-based wireless technology can already meet the needs of transmitting high-definition video data streams, but most of the existing TD-LTE high-definition video application systems are in front-end cameras. Only one network connection method is integrated, even if multiple network connection methods are integrated, network switching cannot be performed intelligently, which greatly limits the convenience of TD-LTE network camera applications. [0003] In addition, most of the existing network handover algorithms are developed for the cell handover / base station handover of the UMTS network, and there are also a small number of algorithms for network lo...
