Background
With the development of the automobile industry and wireless communication technology, the automobile on-board unit is equipped with a plurality of interfaces to access different communication network types, such as: cellular networks, Wi-Fi, etc. Vehicles, as communication nodes in the internet of vehicles, must be able to communicate between vehicles and network access points. However, network users in the car networking are dynamically changeable, and especially in the current 5G ultra-dense networking scenario, the optimal access network under the network coverage of the vehicle may be determined by the movement of the vehicle, the corresponding vehicle-mounted service demand, and the load condition of the surrounding network access entities. There is therefore a need for efficient switching of the networking of vehicles to maintain the communication quality of the vehicles.
The existing networking switching technology mainly comprises the following steps: a switching strategy, a switching control mode, resource management in the switching process, a mobility support protocol and the like. The switching strategy comprises vertical switching and aims at constructing an automatic, rapid and reasonable network selection mechanism and selecting the most appropriate switching triggering time and the best access network meeting the current requirement; the switching control mode is used for determining that a terminal or a network entity initiates network switching operation in the network switching process; the resource management in the switching process comprises the allocation of resources during switching, namely the channel allocation of a link layer, the allocation and binding of a network layer care-of address and the like; the mobility support protocol is used to handle addressing and routing of mobile terminals supporting multiple connections during network handover.
In the network switching under the mobile scene at the present stage, bidirectional state perception is mainly carried out through signaling interaction between a mobile node and an access network, and then a network switching process is started after an optimal access network decision is made through the mobile node or a network access point. Although some existing handover decision algorithms can improve network handover efficiency to some extent and reasonably utilize network resources in an area, they still have some problems, mainly reflected in:
(1) because the mobile node side and the network side need to perform bidirectional state sensing, signaling interaction during the period can affect the time delay of network switching to a certain extent, and a series of unnecessary network overheads are also increased.
(2) Some mobile terminals have limited computing power, and cannot make an accurate handover decision based on the sensed network state information within a limited time, so that subsequent network handover processes and efficiency are affected, and communication interruption may be caused seriously.
(3) Due to the limited communication range of the mobile node, the final network switching decision is only locally optimal due to the lack of global property only by means of signaling interaction and part of network state information sensed by the sensor.
