A pricing-based data offloading method in heterogeneous wireless networks

Abstract

The invention provides a data unloading method based on pricing in a heterogeneous wireless network. The whole network structure comprises a macro cellular data unloading decision center, a macro basestation deployed by a macro cellular network operator and a user terminal thereof, and a low power node deployed by other network operators and a user terminal thereof. A low power node transmits itsnetwork condition and associate terminal information to a macro cellular data offloading decision center, and simultaneously transmits capacity and price that it is willing to use for transmitting macro cellular data. The macro cellular base station transmits the network status and the related information of the associated terminals to the macro cellular data offloading decision center. The macrocellular data offloading decision center executes offloading decision and sends a decision instruction to the macro cellular base station. The macro cellular base station switches the data of the designated macro cellular user terminal to the designated low power node. The invention can effectively improve the throughput of the heterogeneous wireless network and reduce the data congestion.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data unloading method based on pricing in a heterogeneous wireless network. In the heterogeneous wireless network environment, the method alleviates the problem of data congestion in macro cells based on pricing, and at the same time guarantees QoS requirements of user terminals. Background technique [0002] In recent years, with the increasing popularity of smart mobile devices, the business demand of mobile users to access Internet services through smart terminals has grown rapidly, which has greatly increased the pressure on the macro-cellular network deployed by macro-cellular network operators, resulting in network congestion and overload. The user's service experience is reduced. With the popularity of WiFi and femtocell networks, macro cellular network operators can use them to offload customer traffic from macro cellular networks, increase netwo...

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
