Original Abstract

In the latest specifications of the Universal Mobile Telecommunication System (UMTS) networks, the 3GPP defines the IMS technology. That is why the multimedia sessions in the IMS are processed by a set of network elements originally designed to support IP multimedia services in the UMTS. The QoS mapping between IMS services and IP transport is fundamental for maintaining a suitable quality. The differentiation of these two technologies can lead to unpredictable and unwanted behavior for services. The possibility of employing DiffServ and IntServ mechanisms into the IMS environment in order to achieve full QoS support for real-time applications is the object of interest.

V poslední UMTS specifikaci definuje organizace 3GPP technologii IMS. Proto jsou multimediální spojení v IMS zprostředkovány přes síťové elementy původně pro pro přenos multimédií v UMTS. Důraz je kladen na kvalitu real-time služby zajišťující Uživatelům určitou míru spokojenosti. Vzhledem k tomu, že IMS umožňuje dodávat real-time multimediální služby prostřednictvím IP spojení, některé problémy, které zapřičiňují QoS obtížné, je třeba prostudovat. Možnost implementace DiffServ a IntServ mechanismů do prostředí IMS k dosažení plné QoS podpory pro real-time aplikace je předmětem zájmu.
