Wireless access network and baseband function deployment method based on minimum spanning tree

Abstract

The invention discloses a wireless access network and a baseband function deployment method based on a minimum spanning tree. The method includes: according to the network topology diagram of the wireless access network, the minimum spanning tree algorithm is used to generate the following information according to the link length. A tree topology diagram in which the data center DC node of the wireless access network is the root node; on the premise of meeting the delay requirements of the RRU nodes in the wireless access network, each function of the baseband function corresponding to each RRU node The module FU is deployed in the upper layer processing pool nodes of the tree topology diagram as much as possible. The application of the present invention can improve the resource and cost efficiency of network operators, and can greatly improve the flexibility of FU deployment, and can effectively adapt to the objective requirements of future diversified services, low-cost operation and maintenance, and scalable network construction.

Description

technical field [0001] The present invention relates to the field of wireless access networks, in particular to a wireless access network and a baseband function deployment method based on a minimum spanning tree. Background technique [0002] With the continuous evolution of mobile communication technology to the fifth generation (5G) and post-5G (B5G), the future wireless access network will move towards higher speed, lower latency, and more connections, thereby supporting more massive The mobile user base and more diverse business scenarios greatly enhance the human-centered Internet service experience and fully support the object-centered IoT perception applications. However, while the mobile communication technology is iteratively updated, the wireless access network is also facing severe challenges. [0003] Currently, a Centralized Radio Access Network (C-RAN) architecture is widely used in live networks. The traditional macro base station consists of a radio freque...

Problems solved by technology

[0009] Although, for the DU / CU deployment solution under functional segmentation, its resource efficiency and delay performance have been significantly improved compared with the traditional C-RAN mode network architecture solution without functional segmentation, but there are still defects: its functional segmentation The choice is relatively fixed. On the one hand, it limits the development potential of the network that carries diversified services, and on the other hand, its overall bandwidth consumption remains high.

Therefore, the existing baseband function deployment scheme has certain limitations, and it is difficult to effectively adapt to the objective requirements of future diversified services, low-cost operation and maintenance, and scalable network construction.
