Wireless communication network system

Abstract

Conventionally, in a case of occurrence of reduction of transmission speed caused by AMR on a network path currently used for communication in a wireless communication network system, it was disadvantageously impossible to change to another path exhibiting a much higher transmission speed if any. A path selection method according to the invention, which is a method for selecting a path in a communication network using a microwave communication system, selects, as a path used for communication, a path, which exhibits a larger transmission capacity, in accordance with a change of the transmission capacity of each path of the network.

Description

technical field [0001] The present invention relates to controlling routing using AMR (Adaptive Modulation Radio) control of a wireless communication system in a wireless communication network system. Background technique [0002] Communication networks using wireless communication systems (and more specifically, wireless communication networks including point-to-point small-scale microwave communication systems) are attracting attention as means for supplementing optical communication circuits or wireless backbone circuits. Such wireless communication networks have widespread uses such as replacement or backup of cellular telephone networks, communication between buildings and optical communication networks. Recently, a communication system as a base station linking base stations in a rapidly expanding mobile phone network market worldwide has greatly increased demand due to features such as cost performance of equipment, ease of construction, flexibility in system changes,...
