Networking method for integrated bearer of wireless 5G forwarding and other services

Abstract

The invention belongs to the technical field of network communication, and specifically discloses a networking method for an integrated bearer of wireless 5G forwarding and other services. The networking method for an integrated bearer of wireless 5G forwarding and other services comprises the following steps: S1, selecting transmission access nodes; S2, defining the coverage of the transmission access nodes; S3, selecting an aggregation transmission node; S4, determining a network topology map; S5, calculating the bearer bandwidth of the single transmission access node; and S6, calculating the bearer bandwidth on a single access ring. The method is advantageous for solving the problem of excessive consumption of optical cables caused by the dense coverage of 5G sites, can meet the requirement of the forwarding service of a new 5G base station, ensures the quality and speed of the service bearer, has good extensibility, improves the security of a forwarding network, effectively bears large bandwidth services of 5G or other frequency point base stations, improves the manageability and serviceability of the forwarding network, and can comprehensively bear other services and furthestreduce the investment.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a networking method for wireless 5G fronthaul and other services integrated bearer. Background technique [0002] 5G is the abbreviation of the fifth generation communication technology. Compared with 4G, 5G network has stronger performance and supports application scenarios of ultra-high speed, ultra-low latency, and ultra-large connection. As 5G is approaching, due to the 5G spectrum characteristics and the explosive growth of the bandwidth of a single base station, in order to meet the requirements of coverage effect and high-speed bandwidth, the deployment density of base stations will increase, and the deployment location will be closer to users. As the BBU and RRU With the gradual maturity of separation and remote RRU technology, 5G will use DU / BBU centralized deployment in the future, and some 5G remote sites will be co-located with existing 4G remote sites....

Problems solved by technology

As 5G is approaching, due to the 5G spectrum characteristics and the explosive growth of the bandwidth of a single base station, in order to meet the requirements of coverage effect and high-speed bandwidth, the deployment density of base stations will increase, and the deployment location will be closer to users. As the BBU and RRU With the gradual maturity of separation and remote RRU technology, 5G will use DU / BBU centralized deployment in the future, and some 5G remote sites will be co-located with existing 4G remote sites. Therefore, for future 5G ultra-high-density wireless networks, There is an urgent demand for base station fronthaul with deep coverage. Existing base station access fiber resources are generally in short supply. In addition, 5G networks have higher reliability requirements due to the particularity of some services. The existing fiber direct connection bearer fronthaul solution is difficult to meet. 5G base station fronthaul networking mode will be the focus of research
