HLR広域二重化システムの試作および評価  [in Japanese] An Evaluation for HLR Duplex System based on a Prototype System  [in Japanese]

Abstract

移動通信の普及に伴い移動通信網には高い信頼性が要求されており,位置管理機能やサービス制御機能といった重要な機能を持つホーム・ロケーション・レジスタ(HLR)の高信頼化が重要となる.筆者らは,HLRの高信頼化のために,HLRをAct系HLRノードおよびStandby系HLRノードで構成し,Act系HLRノード障害時にStandby系HLRノードでサービスを提供する二重化システムを提案している.本稿では,先ず提案している二重化システムのアーキテクチャ,および本システムの試作構成を示す.続いて,試作システムを用いたノード切り替え処理および欠落情報救済処理に関する評価結果を示す.

According to the wide spread of mobile communication services, a highly reliable home location register (HLR) is required because of its important functions such as location data management function and service control function. We proposed HLR duplex system that is comprised of an act HLR node and a remotely located standby HLR node, and standby HLR node controls services in case of act HLR node failures. In this paper, we first describe our proposed system architecture and its prototype system. And then we show evaluation results of HLR node takeover procedure and inconsistent location information recovery procedure based on the prototype system.
