A traffic flow-assisted wireless data transmission method and device

Abstract

Embodiments of the present invention provide a traffic flow-assisted wireless data transmission method and device, which are applied in the technical field of communication. The method includes: on the base station side, in the idle cell, the idle base station receives the first mobile service data request sent by the hotspot base station; the idle base station obtains and determines the amount of data transmitted from the vehicle terminal to the user terminal according to the traffic condition information on the road surface ; According to the first mobile service data request and data volume, the idle base station sends the mobile service data to the vehicle terminal. For the vehicle-mounted terminal side, the vehicle-mounted terminal receives the mobile service data sent by the idle base station in the idle cell; in the hotspot cell, and when the vehicle is parked, the vehicle-mounted terminal transmits the mobile service data to the user terminal. For the user terminal side, in the hotspot cell, the user terminal sends a mobile service data request to the hotspot base station; the user terminal receives the mobile service data sent by the vehicle 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
