Traffic flow assisted wireless data transmission method and device

Abstract

The embodiment of the invention provides a traffic flow assisted wireless data transmission method and device, applied to the technical field of communication. The method comprises the following steps: for a base station side, an idle base station receives a first mobile service data request sent by a hotspot base station in an idle cell; the idle base station obtains road traffic condition information, and determines the data volume transmitted from a vehicular terminal to a user terminal according to the road traffic condition information; the idle base station sends mobile service data to the vehicular terminal according to the first mobile service data request and the data volume; for the vehicular terminal side, the vehicular terminal receives the mobile service data sent by the idle base station in the idle cell; when a vehicle is in a parking state, the vehicular terminal transmits the mobile service data to the user terminal in a hotspot cell; for the user terminal side, the user terminal sends the mobile service data request to the hotspot base station in the hotspot cell; and the user terminal receives the mobile service data sent by the vehicular terminal.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a traffic flow-assisted wireless data transmission method and device. Background technique [0002] With the rapid growth of personal data services and the network gradually becoming user-centric (that is, network facilities are deployed according to the characteristics of user needs), uneven information density has become one of the problems to be solved by 5G technology. Some typical scenarios, such as shopping malls, residential areas, and main roads, have been included in the 5G project to solve the problem of high-intensity traffic load caused by dense population. The challenge brought by the uneven information density is the contradiction between the overload of hotspot cells and the waste of resources in idle cells, which is especially serious in the bustling areas of metropolitan areas. [0003] For deployed base stations, when the demand suddenly increases in s...

Problems solved by technology

The challenge posed by the uneven information density is the contradiction between the overload of hotspot cells and the waste of resources in idle cells, which is especially serious in the bustling areas of metropolitan areas

[0003] For the base stations that have been deployed, when the demand suddenly increases in some periods or in some specific places, the base stations in this period or in some specific places are prone to overload

The existing solution is to add base stations in these places. For example, during the peak traffic period, there will be high-density traffic demand at traffic intersections. In the prior art, the data load pressure of each base station is reduced by adding base stations in the intersection area. , but adding base stations that operate all day only for peak demand during peak traffic periods will increase investment costs and energy costs, and will also increase the complexity of interference coordination between base stations
