The infrastructure further includes 4G base stations capable of communicating with the UAV along its flight path. An antenna in the base station is capable of supporting a downlink to the UAV. A control centre accepts navigation related data from the uplink. In addition, the control centre further includes a connection to the 4G infrastructure for obtaining downlinked data. A computer for calculating location of the UAV using navigation data from the downlink.

A communication control device is configured to control data communication between terminals using a communication network. The communication control device include: a status-information acquiring unit configured to acquire respective pieces of status information which represent operating states of the terminals; a reception-information acquiring unit configured to acquire respective pieces of reception information which represent states of the communication network when the terminals have received data; a communication determining unit configured to determine a type of communication on the basis of a combination of pieces of status information of multiple terminals that participate in the same communication; and a quality control unit configured to control quality of data that each terminal transmits or receives on the basis of the determined type of communication and the acquired reception information.

An example of a building automation system utilizes intelligent system elements, some of which are lighting devices having light sources, and some of which are utility building control and automation elements. Some utility building control and automation elements include a controllable mechanism for use in control of some aspect of the building other than lighting. Another intelligent system element may include either a user interface component and be configured as a building controller, or include a detector and be configured as a sensor. Each intelligent system element includes a network communication interface, processor, memory and programming to configure the intelligent system element as a lighting device, utility building control and automation element, controller or sensor. At least one of the intelligent lighting devices is configured as a building control and automation system server. Several examples, however, implement the overall control using distributed processing.

The present invention discloses methods and systems for forward packets received from a SSID at a wireless access point to a VPN. The SSID and VPN are associated. The VPN is created according to a VPN profile. When the VPN is established, the SSID is enabled. When the VPN is not established, the SSID is disabled.

A packet processing method and a network device in a hybrid access network. The method comprises sending, by a first network device, a first data packet in a first sending window to a second network device by using a first tunnel. In response to receiving a first acknowledgement response sent by the second network device, increasing, by the first network device, a size of the first sending window based on a first proportion. In response to not receiving, within a first predetermined time, the first acknowledgement response, decreasing the size of the first sending window based on a second proportion; and in response to determining that the size of the first sending window is greater than or equal to a first threshold, sending a second data packet to a second receiving window of the second network device by using a second sending window.
