Vehicle-mounted communication method, vehicle-mounted communication device and vehicle-mounted communication system

Abstract

An embodiment of the invention discloses a vehicle-mounted communication method. The vehicle-mounted communication method comprises the steps of acquiring a position where a vehicle is located currently, acquiring all of fixed access points (AP), wherein distances between the position where the vehicle is located currently and all of fixed AP are smaller than a maximum transmission distance; scanning all of fixed AP within a dispatching cycle and selecting at least one fixed AP with signal strength larger a preset value in the all of fixed AP as a fixed AP to be accessed according to scanning results; and triggering a mobile terminal in the vehicle to be respectively accessed to a vehicle-mounted AP and the fixed AP to be accessed within the dispatching cycle an according to allocated time when an accessing condition is met. Accordingly, the embodiment of the invention further discloses a vehicle-mounted communication device and a vehicle-mounted communication system. By means of the technical scheme, when the accessing condition is met, the mobile terminal in the vehicle can be connected to the fixed AP nearby the current position, accordingly communication bandwidth is increased, and business with large data volume is supported.

Description

technical field [0001] The present invention relates to the communication field, in particular to a vehicle communication method, device and system. Background technique [0002] With the development of wireless technology and handheld devices, more and more users will use various Internet services when communicating; buses in cities have the characteristics of fixed routes and large passenger flow, and now many cities have implemented wireless city According to the scheme, on both sides of many roads, such as telephone booths, access points of wireless WLAN (Wireless Local Area Network, wireless local area network) are arranged. [0003] At present, operators are already paying attention to the situation of in-vehicle communication. In Hong Kong, PCCW (Pacific Century Cyber ​​Works Limited) has deployed in-vehicle communication systems on multiple lines, deploying access devices in buses using WLAN technology For the wireless coverage in the car, the backhaul link uses cel...

AI Technical Summary

Problems solved by technology

[0004] Therefore, in the current vehicular communication environment, the user's communication bandwidth is limited by the bandwidth of the link back to the city. When many users access the Internet through the vehicular access device, because the bandwidth of the cellular network is narrow, each user can get Very little bandwidth, unable to support high-speed data services, such as multimedia services, etc.
