Embodiment Construction

[0027] Reading and understanding the following detailed description of the embodiments of the present invention with reference to the accompanying drawings will make the purpose of the present invention, the problem to be solved and its features easy to understand. In order to express the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. figure 1 Three main communication modes in the Internet of Vehicles are exemplarily described: V2V communication, V2I communication and HV communication. V2V communication refers to direct or multi-hop communication between vehicles, which does not depend on roadside infrastructure (for example, BS of cellular network and AP of WLAN, etc.), such as figure 1 In the communication between car B and car C, car D and car E. V2I communication refers to the communication between vehicl...

Abstract

The invention relates to the internet of vehicle access selection technology in the field of intelligent transportation, and discloses a subscriber access terminal selecting device and method supporting multi-hopping wireless local area network (WLAN) in the internet of vehicles. The method includes: collecting the surrounding available access point (AP) and relay station (RS) state information, enabling an information analyzing and processing module to analyze and process service requirements and various types of information, and performing comprehensive evaluation on the service characteristics of new subscribers and state information of the waiting AP and RS so as to achieve switching control. The subscriber access terminal selecting device supports selection on mobile subscriber access modes and optimum AP / RS under the hybrid communication scene of the network of vehicles, achieves load balancing among the APs by means of access selection and switching control and improves the comprehensive performance and subscriber satisfaction degree on quality of service (OoS).

Description

technical field [0001] The invention relates to an access selection technology in the communication field, in particular to a mobile user access selection terminal technology in the Internet of Vehicles. Background technique [0002] At present, the research and application in the field of intelligent transportation (Intelligent Transport System, ITS) has attracted widespread attention, and the Internet of Vehicles, which uses automobiles as nodes and is based on networks, and the coordinated development of people, vehicles, roads, and networks, is an important part of ITS. Provide effective technical support and implementation basis for many user applications. In the application of Internet of Vehicles, the global positioning system (GPS), sensing technology and various network access technologies such as cellular network, WLAN, Adhoc technology, etc. are organically combined to provide an effective network access for moving vehicles and realize vehicle Communication with ...
