Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] figure 1 It is a schematic diagram of the distribution system based on user tags in the 5G network of the present invention. As shown in the figure, in order to meet future network and service requirements, on the centralized hierarchical C-RAN 5G network architecture, user experience in a complex heterogeneous network environment is realized improvement. The WiFi distribution system consists of hierarchical local cloud platforms:

[0032] 1) The local cloud platform is the cloud platform closest to the user, which is mainly responsible for scheduling and managing a certain number of WiFi access point APs to realize centralized management of network resources;

[0033] 2) The 5G network architecture consists of multi-level local cloud platforms;

[0034] Adjacent local cloud platforms are interconnected through optical fiber, enab...

Abstract

The invention relates to a user tag based shunt method and system in a 5G network, belonging to the technical field of communications. On the basis of a C-radio access network (C-RAN) architecture, a user tag is analyzed and extracted by a deep packet inspection (DPI) module, and a shunt strategy is deployed on an access network discovery and selection function (ANDSF), so as to realize WiFi shunt in a 5G complex heterogeneous network. The shunt method and system comprehensively consider three aspects of factors, namely, user preference, service requirements and network performances. For dense and complex distribution of WiFi in future 5G network and the heterogeneous network environment in which WiFi and 5G network are further fused, the method and system well solve the problem of WiFi shunt. The method and system mainly comprise a WiFi shunt trigger unit. An access point (AP) proactively reports or passively reports network state information. A DPI unit analyzes and acquires the user tag. The ANDSF executes the shunt strategy, ranks candidate WiFi, and starts the shunt switching process. The method and device can simultaneously satisfy service requirements and achieve the purpose of network resource dynamic match, improve the user quality of experience (QoE), balance network load, and realize benefit maximization of the user and network operators.

Description

technical field [0001] The invention belongs to the field of communication technology, and relates to a method and system for offloading based on user tags in a 5G network, in particular to a method and system for offloading and user tagging based on C-RAN for WiFi. Background technique [0002] With the commercialization and widespread deployment of 4G networks, users can enjoy increasingly high-speed data services. The rich applications of the mobile Internet, such as OTT, social networking, file download, real-time video, etc., have further stimulated the use of mobile devices (smart machines, tablets, etc.) by users. According to the traffic data forecast report released by Cisco in February 2014, from 2013 to 2018, mobile data traffic will grow at a compound annual growth rate of 61%. Therefore, the downlink traffic load of the cellular network increases sharply, and the workload of network equipment increases greatly. The transmission link is congested, and the end-t...
