Embodiment Construction

[0067] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0068] like figure 1 As shown, this embodiment provides a connection relationship between the fronthaul network and RRUs and BBUs. Obviously, one end of the FTN is connected to the RRU to obtain the data submitted by the terminal to the RRU, and the other end is connected to the BBU to transmit the data from the RRU to the BBU, and at the same time transmit the data sent by the BBU to the RRU, which can be stored by the RRU itself or sent to the terminal.

[0069] like figure 2 As shown, this embodiment provides a network architecture of a fronthaul network. The FTN includes an access type fronthaul transmission node (FTN-ACC) and an aggregation type fronthaul transmission node (FTN-AGG); the FTN-ACC is connected to the RUU; and the FTN-AGG is connected to the BBU. The FTN-ACC may be connected to the RRU...

Abstract

The invention discloses a control method and device for a front-haul transport network (FTN). The method comprises: detecting traffic situation information on a radiofrequency wireless network side; analyzing the traffic situation information, determining a time delay requirement and a required bandwidth of the traffic; and determining the network configuration parameter of the FTN according to the time delay requirement and the required bandwidth of the traffic; and transmitting the network configuration parameter to the FTN, wherein the network configuration parameter is used by the FTN for network configuration. The method dynamically determines the network configuration of the FTN based on the traffic situation information, solves a problem that the FTN is statically configured in the prior art so as to cause a high no-load degree and thus large power consumption and a low resource utilization rate, and has a low no-load rate, low power consumption and high resource utilization efficiency.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a fronthaul network control method and device. Background technique [0002] A front-haul transport network (Front-haul Transport Network, FTN) is a transmission network located between a remote radio unit (Remote Radio Unite, RUU) and a baseband processing unit (Base Band Unite, BBU). The front end of the FTN is connected to the RUU, and the back end is connected to a BBU pool composed of multiple BBUs. The BBU pool may be called BBUs for short. [0003] However, in specific applications, there is often no-load phenomenon, which leads to the problems of high power consumption and low effective utilization of resources in FTN. Contents of the invention [0004] In view of this, the embodiments of the present invention expect to provide a fronthaul network control method and device, which at least partially solve the above problems. [0005] In order to achieve the a...
