Abstract

The invention relates to the technical field of communication, in particular to a task unloading method of a heterogeneous cellular network. The method comprises the steps as follows: a user unloadingtask request is established and parameters are preset; a lyapunov function and a target function are constructed; the queue backlog is minimized while the user unloading utility is maximized, a method for solving the optimal unloading amount is selected according to the effect of network heterogenization on user unloading tasks and whether the WIFI connection lime is determined, that is, if the set WIFI connection time is determined, a lagrangian optimization method is adopted to solve the optimal unloading amount; otherwise, stochastic programming is adopted to solve the optimal unloading amount. The user system unloading utility maximization is considered, the unloading queue backlog is reduced, and the user mobility and the effect of network heterogenization on the user unloading tasksare considered, so that the backlog of user unloading tasks is substantially reduced and system jam is reduced while the user unloading utility is maximized.

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...
