Description
本件出願は、2012年7月14日に出願された米国特許仮出願第61/671,691号の利益を主張するものであり、その開示の全体が引用によりここに援用される。
本明細書に記載される主題は、通信ネットワークにおける輻輳を制御するための方法およびシステムに関する。より特定的には、本明細書に記載される主題は、無線アクセスネットワークにおける輻輳を動的に制御するための方法、システム、およびコンピュータ読取可能媒体に関する。
無線事業者は、ネットワークにおけるデータの氾濫に対処する努力を行っており、事業目的に適合するように無線スペクトラムの優先順位付けを確実に行う。移動体通信事業者は、移動体通信ネットワークにおけるアクセス量の増大(たとえば、スマートフォン採用の増加率)およびデータフロー量の増大(たとえば、ネットワークにおけるデータ使用の増加率)の両方からの圧力を受ける。事業者所有サービスを用いることによって資本支出および事業支出の増加を相殺する以前の方法は、音声サービスが優勢を占めていた世界ほど有効ではない。
一局面によれば、本明細書に記載される主題は、無線アクセスネットワークにおける輻輳を動的に制御するためのシステムを含む。システムは、ポリシーおよび課金ルール機能(PCRF)を含み、ポリシーおよび課金ルール機能(PCRF)は、無線アクセスネットワークを介してユーザ機器と通信するためのノードから承認要求を受け取り、承認要求の受け取りに応答して、無線アクセスネットワークにおける輻輳を制御する加入者特定ポリシーをノードにインストールする。
本明細書に開示される主題に従い、無線アクセスネットワークにおける輻輳を制御するために、システム、方法、およびコンピュータ読取可能媒体が提供される。ここで本発明の例示的な実施形態が詳細に参照され、これらの例は添付の図面に示される。可能な場合は、同じまたは同様の部分を参照するために図面の全体において同じ参照符号が用いられる。
