Problems solved by technology

The 5G fronthaul network is based on the active antenna unit (AAU, Active Antenna Unit) and distribution unit (DU, Distribute Unit) + centralized unit (CU, Centralized Unit) architecture. The DU+CU in the CRAN scenario will connect multiple wireless stations (such as 6-8), in this scenario, each wireless station needs 12 fibers, which consumes a lot of fibers for the fronthaul network
However, there is currently no effective solution for how to realize the management and control of the fronthaul network

Abstract

The embodiment of the invention discloses a management control method and equipment for a new forward transmission network. The method comprises the following steps that wavelength division multiplexing (WDM) equipment acquires a first optical signal, wherein the first optical signal is obtained by multiplexing multiple paths of optical signals; the WDM equipment performs light splitting processing on the first optical signal to obtain a plurality of second optical signals, and sends the second optical signals to corresponding service optical modules, wherein the first optical signal and the second optical signal are both multi-wavelength optical signals.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a management and control method and equipment for a new fronthaul network. Background technique [0002] With the arrival of the fifth generation mobile communication network (5G), the fronthaul network is gradually carried by a centralized radio access network (CRAN, Centralized Radio Access Network). The 5G fronthaul network is based on the active antenna unit (AAU, Active Antenna Unit) and distribution unit (DU, Distribute Unit) + centralized unit (CU, Centralized Unit) architecture. The DU+CU in the CRAN scenario will connect multiple wireless stations (such as 6-8), in this scenario, each wireless station needs 12 optical fibers, which consumes a lot of optical fibers for the fronthaul network. [0003] In order to solve the problem of using a large number of optical fibers, the fronthaul network can use wavelength division multiplexing equipment to realize fronthaul fib...
