Network monitoring method, network monitoring apparatus, line failure prevention system and computer program of network monitoring apparatus

A network monitoring apparatus which is connected with a meteorological data server and a radio communication network and which monitors said radio communication network, said network monitoring apparatus including a processor, wherein said processor, as said predetermined process, carries out,

• a predicted amount of rainfall obtaining process to obtain a predicted amount of rainfall generated in a predetermined time in a current line route of said radio communication network on the basis of a weather forecast data of said meteorological data server;
• a prediction process to predict whether or not a line failure occurs in said current line route caused by said predicted rainfall assuming that it rains actually in said current line route with an amount of rainfall substantially equivalent to said predicted amount of rainfall in said predetermined time in said current line route;
• and
• a change instruction process to instructs said radio communication network to change said current line route into a different line route on which it is predicted that no line failure caused by rainfall occurs and to control said radio communication network to change said current line route into said different line route, before said predetermined time passes, when it is predicted that said line failure occurs in said current line route.

A line failure prevention system, comprising;

• a meteorological data server;
• a radio communication network;
• and
• a network monitoring apparatus which is connected with said meteorological data server and said radio communication network and monitors said radio communication network, wherein
• said network monitoring apparatus includes a processor, and wherein
• said processor, as said predetermined process, carries out,
• a predicted amount of rainfall obtaining process to obtain a predicted amount of rainfall generated in a predetermined time in a current line route of said radio communication network on the basis of a weather forecast data of said meteorological data server;
• a prediction process to predict whether or not a line failure occurs in said current line route caused by said predicted rainfall assuming that it rains actually in said current line route with an amount of rainfall substantially equivalent to said predicted amount of rainfall in said predetermined time in said current line route;
• and
• a change instruction process to instructs said radio communication network to change said current line route into a different line route on which it is predicted that no line failure caused by rainfall occurs and to control said radio communication network to change said current line route into said different line route, before said predetermined time passes, when it is predicted that said line failure occurs in said current line route.

A program for a network monitoring apparatus which is connected with a meteorological data server and a radio communication network and which monitors said radio communication network, said network monitoring apparatus including a processor and a memory, said memory storing a program for said processor to carry out a predetermined process and working as a temporary memory when said processor executes said program, wherein

• said program controls said processor to carry out, as said predetermined process,
• a predicted amount of rainfall obtaining process to obtain a predicted amount of rainfall generated in a predetermined time in a current line route of said radio communication network on the basis of a weather forecast data of said meteorological data server;
• a prediction process to predict whether or not a line failure occurs in said current line route caused by said predicted rainfall assuming that it rains actually in said current line route with an amount of rainfall substantially equivalent to said predicted amount of rainfall in said predetermined time in said current line route;
• and
• a change instruction process to instructs said radio communication network to change said current line route into a different line route on which it is predicted that no line failure caused by rainfall occurs and to control said radio communication network to change said current line route into said different line route, before said predetermined time passes, when it is predicted that said line failure occurs in said current line route.
