Method, device and system for performing frequency planning in wireless Mesh returning network

Abstract

The invention discloses a method for performing frequency planning in a wireless Mesh returning network, which comprises the following steps: according to the traffic load reference gross in the wireless Mesh returning network, determining the total number of first type frequency blocks for performing fixed allocation in frequency resources, wherein the first type frequency blocks are used when performing communications between each network node and other network nodes having master-slave relations; according to the total number of the first type frequency blocks and the traffic load of each network node, determining the number of the first type frequency blocks required to be allocated to each network node; and according to the number of the first type frequency blocks required to be allocated to each network node, allocating corresponding number of the first type frequency blocks to each network node. Thus, the complexity of a frequency planning scheme is reduced effectively on the basis of ensuring the spectrum effectiveness, and the increase of network load is avoided. The invention simultaneously discloses a communication device and the wireless Mesh returning network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for frequency planning in a wireless Mesh backhaul network. Background technique [0002] With the development of technology, the next-generation wireless communication system combines multiple wireless access technologies to form a converged network, providing end users with ubiquitous high-speed broadband access. These accesses include, for example, third-generation and fourth-generation (3G / 4G) mobile communication systems, wireless local area networks (WLANs) represented by the IEEE802.11 standard series, and emerging wireless networks represented by the IEEE802.16 standard series (WiMAX). broadband wireless access technology (Broadband Wireless Access, BWA) and so on. [0003] Wireless Mesh backhaul network (Wireless Mesh Network, WMN) is also one of the key factors to build the future aggregation network. It uses multi-hop self-organizing (ad ...

Problems solved by technology

This makes the existing frequency allocation scheme highly dynamic and requires high real-time information. Therefore, with the continuous change of business load and communication links in the network, it is necessary to make adjustments to the allocation of frequency resources at any time. Correspondingly adjusted, this will greatly increase the transmission volume of control signaling, thereby causing serious network load, and at the same time, it also increases the complexity of the frequency allocation scheme
