Claim:
1. A base station congestion management system configured to determine whether congestion is occurring at a base station in a network in which a plurality of base stations distribute data from a user terminal to a plurality of gateway apparatuses, wherein a plurality of communication monitoring apparatuses collect base station bandwidth information which includes identification information of at least one base station which communicates with the gateway apparatus managed by each communication monitoring apparatus and a used bandwidth between the gateway apparatus and the at least one base station, and subscriber information which includes subscriber identification information of the user terminal and identification information of a base station with which the user terminal is connected, the base station congestion management system comprising: at least one data management unit to which the plurality of communication monitoring apparatuses input the base station bandwidth information and the subscriber information; a shared data store configured to store base station bandwidth usage information which registers therein a total value of a used bandwidth of the base station bandwidth information inputted to the data management unit from the plurality of communication monitoring apparatuses for each base station, and information of list of subscriber existing within base station coverage which registers therein a list of subscriber identification information of a user terminal connected with the base station for each base station; and a congestion management unit configured to determine whether congestion is occurring at the base station, wherein the data management unit calculates a total value of a used bandwidth for each base station based on the base station bandwidth information inputted from the communication monitoring apparatus, wherein the data management unit updates the base station bandwidth usage information in the shared data store based on the calculated total value, wherein the data management unit updates the list of subscriber identification information of a user terminal connected with the base station of the information of the list of subscriber existing within base station coverage in the shared data store based on the subscriber information inputted from the communication monitoring apparatus, wherein the congestion management unit determine whether congestion is occurring at the base station based on the total value of the used bandwidth for each base station of the base station bandwidth usage information in the shared data store, and wherein the congestion management unit refers to the information of list of subscriber existing within base station coverage in the shared data and identifies the subscriber identification information of the user terminal connected with the base station where congestion is occurring.
