Description

Method for controlling node, network node and access network

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for controlling a node, a network node, and an access network.

Background technique

The development of technology and society will bring about a surge in mobile and wireless traffic. After ten years, the amount of mobile broadband services will reach more than a thousand times today. The prior art is difficult to achieve this by increasing spectral efficiency, and the use of large bandwidths in high frequency bands has become an inevitable trend.

Compared with low-frequency signals, high-frequency signals have more serious propagation loss and poorer penetrating power, so the transmission distance of high-frequency signals is very short. The future high-frequency network will be an ultra-dense network, which is characterized by: short node spacing and high density. Due to the large number of nodes, if each node is transmitted back to the core network through wired fiber, the high cost of fiber deployment will limit the promotion of such dense networks. Therefore, when deploying a network, a preferred solution may be to select several nodes of a plurality of nodes to access the core network through wired fibers, and most other nodes are connected to the several wires through high frequency wireless backhaul. The returned nodes are thus connected to the core network, which saves fiber deployment costs. However, there is no solution in the prior art for establishing a high frequency wireless backhaul link between nodes in a high frequency system.

In the prior art, there is a scheme for a new network node to access a network in a low-frequency wireless communication system, the main content of which is: when a new network element RS (Relay Station) accesses the network, scanning the preamble of the neighbor node, according to The scanning result first selects the access point RS1 to access the network, and feeds the scan result to the multi-hop base station (MR-BS) through the RS1. After the MR-BS receives the RS neighbor measurement report of the RS feedback, According to the network status (such as congestion and load conditions) and the scan result fed back by the RS, the new access point RS2 is selected for the RS, and the preamble information of the new access point RS2 is sent to the RS, and the RS receives the MR-BS. After the information, the acknowledgment response is fed back to the MR-BS, and the received preamble information is detected as the preamble of the current access point RS1. If not, the new access point RS2 is used to access the network.

The above solution in the prior art is still a scheme in a low frequency system, and the omnidirectional antenna is used for transmitting and receiving, and the signals of all neighbor nodes can be scanned when the new network element is added, so the letter of the neighbor node is scanned first. The number is then fed back to the control base station, but in the high frequency system, the beam of the node is very narrow, the new network element cannot scan the signal of the neighbor node or the signal of the neighbor node can be scanned for a long time, so in the scheme Can not be extended to high frequency systems.
