Description

一种数据分流方法、移动边缘平台以及核心网设备Data distribution method, mobile edge platform and core network device

技术领域Technical field

本申请实施例涉及到通信领域，尤其涉及到一种数据分流方法以及移动边缘平台和核心网设备。The embodiments of the present application relate to the field of communications, and in particular, to a data offloading method and a mobile edge platform and a core network device.

背景技术Background technique

移动边缘计算(英文全称：Mobile Edge Computing，简称：MEC)在靠近移动用户的无线接入网(英文全称：Radio Access Network，简称：RAN)上提供互联网技术(英文全称：Information Technology，简称：IT)服务环境和云计算能力，创造了一个高度分布的环境用来部署应用和服务，并且可以存储和处理数据；MEC还可以开放实时的无线网络信息，为移动用户提供个性化、上下文相关的业务体验。实现MEC概念的移动边缘***由三大部分组成，最上层的管理部分，管理***的资源，策略和配置；中间的移动边缘服务器，由服务器管理部分和服务器组成，服务器管理部分提供平台的管理，应用的管理，服务器资源的管理和应用策略的管理，服务器为平台和应用提供安全的运行环境；最底层的网络部分为服务器所部署的位置。Mobile Edge Computing (English name: Mobile Edge Computing, MEC for short) provides Internet technology on the wireless access network (English name: Radio Access Network, RAN for short) (English name: Information Technology, IT for short) The service environment and cloud computing capabilities create a highly distributed environment for deploying applications and services, and can store and process data; MEC can also open real-time wireless network information to provide personalized, context-sensitive services for mobile users. Experience. The mobile edge system that implements the MEC concept consists of three parts, the uppermost management part, the management system resources, strategy and configuration; the middle mobile edge server, which consists of the server management part and the server, and the server management part provides the platform management. Application management, server resource management and application policy management, the server provides a secure operating environment for the platform and applications; the lowest layer of the network is the location where the server is deployed.

移动边缘服务器实际上是部署在移动网络边缘的一个应用服务器，可以截获到移动边缘网络的用户设备(英文全称：User Equipment，简称：UE)发送的数据并进行业务处理，且移动边缘服务器的基础设施中的数据面具有数据分流的功能，即该数据面可以将接收到的数据进行过滤分类再进行发送。The mobile edge server is actually an application server deployed at the edge of the mobile network. It can intercept the data sent by the user equipment of the mobile edge network (English name: User Equipment, UE for short) and perform service processing, and the basis of the mobile edge server. The data plane in the facility has the function of data offloading, that is, the data plane can filter and classify the received data and then send it.

当UE为特定UE时，即该UE拥有多重身份特征，比如该UE可以既是企业用户也可以是移动用户，若移动边缘服务器不实施数据分流机制，则该UE发送的所有数据需要通过核心网转发，即需要通过核心网发送到企业网。由于核心网的带宽负荷高，导致该UE发送数据时产生慢接入，低带宽，高时延的业务体验。When the UE is a specific UE, that is, the UE has multiple identity features, for example, the UE may be both an enterprise user and a mobile user. If the mobile edge server does not implement a data offloading mechanism, all data sent by the UE needs to be forwarded through the core network. That is, it needs to be sent to the enterprise network through the core network. Due to the high bandwidth load of the core network, the UE generates slow access, low bandwidth, and high latency service experience when transmitting data.
