A Pricing-Based Data Offloading Method in Heterogeneous Wireless Networks

Abstract

The present invention proposes a data offloading method based on pricing in a heterogeneous wireless network. The entire network architecture includes a macro cellular data offloading decision center, macro base stations deployed by macro cellular network operators and their user terminals, and deployed by other network operators. Low power nodes and their user terminals. The low-power node sends its network status and associated terminal information to the macro cell data offloading decision center, and at the same time sends the capacity and price it is willing to use to transmit macro cell data; the macro cell base station sends its network status and associated terminal related information to Offload decision center for macro cell data. The macro-cell data offloading decision-making center executes the offloading decision, and sends a decision instruction to the macro-cell base station, and the macro-cell base station switches the data of the specified macro-cell user terminal to the specified low-power node. The invention can effectively improve the throughput of the heterogeneous wireless network and relieve data congestion.

Description

Technical field [0001] The present invention relates to the field of wireless communication technologies, in particular, a pricing-based data unloading method in a heterogeneous wireless network, which is based on pricing in a heterogeneous wireless network environment, slowly reduces macro cell data congestion, while ensuring macro honeycomb The service quality requirements of the user terminal. Background technique [0002] In recent years, with the increasing popularity of intelligent mobile devices, mobile users will grow rapidly through intelligent terminals, and greatly increase the pressure of macro cell network operators deployed, resulting in network congestion and overloading phenomenon. Reduce the user's business experience. With the popularity of WiFi and femtocell network, the macro cell network operator can use them to uninstall customer traffic from the macro network, increase network throughput and reduce the energy consumption of wireless access network infrastru...

Problems solved by technology

[0003] Purpose of the invention: In order to solve the above-mentioned technical problems, the present invention aims at the fact that traditional macrocellular networks cannot meet the ever-increasing demand for user data traffic, and the WiFi access points (or femtocell base stations) deployed by other network operators have their inherent private properties, unwillingness to provide data offloading services for macro cellular network operators, and propose a pricing-based data offloading method in heterogeneous wireless networks
