Abstract

The present invention relates to the field of communication technology, in particular to a task offloading method for a heterogeneous cellular network, comprising: establishing a user offloading task request and presetting parameters; constructing a Lyapunov function and an objective function; maximizing user offloading utility while minimizing According to the impact of network heterogeneity on its users’ unloading tasks, whether the WIFI connection time is determined and the method to solve the optimal unloading amount, that is, if the set WIFI connection time is determined, the Lagrangian optimization method is used to solve it Optimum unloading amount; otherwise, stochastic programming is used to solve the optimal unloading amount; the present invention considers the maximization of user system unloading utility, reduces the backlog of unloading queues, considers the mobility of users, and the influence of network heterogeneity on its user unloading tasks, so that users While maximizing the offloading utility, it not only greatly reduces the backlog of offloading tasks at the user end, but also reduces system congestion.

Description

[0001] The invention relates to the technical field of cloud computing, in particular to a task offloading method of a heterogeneous cellular network. Background technique [0002] In the "mobile" era, industries are accelerating mutual penetration and integration, while technology and services are still the focus of competition. According to data released by the international market research organization eMarketer, the number of people using smartphones in the world has exceeded 2 billion in 2016. The smart phone market tends to be saturated, and related businesses based on smart phones have entered a stage of rapid development. These businesses include mobile payment, mobile games, mobile e-commerce, mobile information, mobile travel, etc. However, mobile terminals (such as smart phones and tablet computers) are important tools for people to handle business, and more and more people put important business on mobile terminals to run. Compared with desktop computers, mobile t...
