Abstract

A base station congestion management includes at least one data management unit to which a plurality of communication monitoring apparatuses input the base station bandwidth information and the subscriber information, a shared data store to store base station bandwidth usage information and information of list of subscriber existing within base station coverage, and a congestion management unit to determine whether congestion is occurring at the base station. The data management unit calculates a total value of a used bandwidth for each base station, updates the base station bandwidth usage information, and updates the list of subscriber identification information of a user terminal connected with the base station. The congestion management unit identifies the subscriber identification information of the user terminal connected with the base station where congestion is occurring.

First claim

What is claimed is:

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.

2 . The base station congestion management system according to claim 1 ,
wherein the system comprises a plurality of data management units, wherein the plurality of data management units, in a case where the base station bandwidth information is inputted from the communication monitoring apparatus, each execute a base station bandwidth usage information update process, wherein the base station bandwidth usage information update process includes a step that each data management unit reads out from the base station bandwidth usage information in the shared data store the total value of the used bandwidth corresponding with the identification information of the base station included in the inputted base station bandwidth information, a step that each data management unit adds the used bandwidth included in the inputted base station bandwidth information to the total value of the used bandwidth which is read out, and a step that each data management unit updates the total value of the used bandwidth corresponding to the identification information of the base station of the base station bandwidth usage information to include the added value, and wherein the plurality of data management units execute in parallel the base station bandwidth usage information update process.

3 . The base station congestion management system according to claim 2 ,
wherein the plurality of data management units, in a case where the subscriber information is inputted from the communication monitoring apparatus, each execute information of list of subscriber existing within base station coverage update process, wherein the information of list of subscriber existing within base station coverage update process includes a step that each data management unit reads out from the information of list of subscriber existing within base station coverage in the shared data store a list of the subscriber identification information corresponding with the identification information of the base station included in the inputted subscriber information, a step that each data management unit adds the subscriber identification information included in the inputted subscriber information to the read out list of the subscriber identification information, and a step that each data management unit updates the list of the subscriber identification information corresponding to the identification information of the base station of the information of list of subscriber existing within base station coverage to include the list of the added subscriber identification information, and wherein the plurality of data management units execute in parallel the information of list of subscriber existing within base station coverage update process.

4 . The base station congestion management system according to claim 3 ,
wherein the subscriber information collected by the communication monitoring apparatus further includes type identification information configured to indicate a type of data transmitted and received by a user terminal of the subscriber, and wherein the information of list of subscriber existing within base station coverage update process includes a step that the data management unit adds, to the list of the read out subscriber identification information, the subscriber identification information whose type, which is identified by the type identification information included in the inputted subscriber information, includes a predetermined type.

5 . The base station congestion management system according to claim 3 ,
wherein the data management unit, in a case where an execution of the base station bandwidth usage information update process and the information of list of subscriber existing within base station coverage update process is completed, writes to the shared data store writing status information which includes the identification information thereof and information that both the processes have been completed, wherein the congestion management unit holds the identification information of the data management unit necessary for executing a determination process of whether congestion is occurring at the base station, wherein the congestion management unit refers to the writing status information in the shared data store, and determines whether information indicating that the both processes, which correspond to all of the identification information of the data management unit necessary for executing the determination process for whether congestion is occurring at the base station, are completed is registered therein, and wherein the congestion management unit, in a case where it is determined that the information indicating that the both processes, which correspond to all of the identification information of the data management unit necessary for executing the determination process for whether congestion is occurring at the base station, are completed is registered, determines whether congestion i
