Software definition based ultra-dense wireless network system structure and implementation method thereof

Abstract

The invention discloses a software definition based ultra-dense wireless network system structure and an implementation method thereof. A whole network framework is realized by a cloud platform; network resources, computing resources and storage resources are managed in a centralized mode, so that network control function reconstruction can be quickly realized; and a future operator also can combine the network resources, the computing resources and the storage resources according to needs, so that quick development and deployment of new business are facilitated. On an access part, virtual cells are used as control planes, a local centralized control node is arranged in each virtual cell, and access nodes of the cell are controlled in the centralized mode, so that unified disposition and coordination of the nodes are completed, and the nodes are used as virtual connecting anchor points. A service transmission carrier of a user terminal is dynamically positioned in the access node close to the user terminal; and when the user terminal moves, a transmission node list set serving a user plane is dynamically updated along with movement of the user terminal. The two nodes separately have two different functions, so that a self-adaptive networking strategy for the control plane and a user data plane is realized.

Description

technical field [0001] The invention designs a software-defined ultra-dense wireless network architecture, which is applied to public services, public services and industry / enterprise services, and belongs to the technical field of wireless communication. Background technique [0002] With the rapid development of Internet applications and the explosive increase in demand for data services, wireless networks are facing enormous challenges. Ultra Dense Network (UDN) is an important solution to this challenge and one of the core technologies of the fifth generation (5G) communication system. In recent years, ultra-dense wireless networks have become one of the hot issues of widespread concern at home and abroad. [0003] The ultra-dense wireless network constitutes a wireless network of multiple micro-cells by densely deploying base stations and antennas, which can increase the coverage of wireless signals, improve system capacity and energy efficiency, but presents a technol...

AI Technical Summary

Problems solved by technology

[0006] The traditional network is centered on transmission nodes, and user access, residency, and handover are all associated with physical transmission nodes, lacking the ability to perceive users and services, programmability of network element functions, and network orchestration capabilities. Flexible construction of network architecture, function configuration, and opening to the outside world are required to achieve fast and agile service deployment and upgrades. It is difficult to meet the different characteristics of ultra-dense network application scenarios and business forms, and the huge difference in network requirements.
