Abstract
IMS (engl. IP multimedia subsystem) - IP multimedijski podsustav - je standardizirana mrežna arhitektura nove generacije koja je zamišljena za operatere telekomunikacijskih usluga da pruže složene usluge u mobilnim i fiksnim mrežama. IMS je arhitekturalni okvir orijentiran na pružanje trenutnih i budućih internet usluga fiksnim i mobilnim korisnicima preko višepristupne IP platforme. IMS je definiran skupinom standarda koji je napravio 3GPP (engl. The 3rd Generation Partnership Project) i 3GPP2. IMS omogućuje operaterima telekomunikacijskih usluga stvaranje infrastrukture usluga otvorenog tipa bazirane na IP-u što omogućuje brzi razvoj novih multimedijskih komunikacijskih usluga kombinirajući telekomunikacijske i podatkovne usluge. QoS se u telekomunikacijskim mrežama definira kao niz specifičnih zahtjeva koje mreža mora ispuniti korisniku, a koji su potrebni kako bi se postigla potrebna funkcionalnost aplikacije (usluge). Korisnici određuju potrebne zahtjeve u obliku QoS parametara. Kvaliteta usluge može biti ključna na poslovnom tržištu. QoS parametri su nužni za indikaciju kvalitete usluge ili proizvoda, te su važan čimbenik u određivanju usluge između različitih pružatelja usluga. Ako su cijene usluga slične, kvaliteta postaje ključni čimbenik za korisnike. Čimbenici koji uzrokuju degradaciju QoS su sljedeći: zagušenje (engl. bottleneck - usko grlo), kašnjenje, djeljeni komunikacijski kanali i mreže s ograničenom propusnošću s lošim upravljanjem kapacitetom Kako bi se pružila i održala QoS, upravljanje resursima mora voditi računa o sljedećim parametrima: dostupnost resursa, kontrola resursa, QoS zahtjevi aplikacija
Abstract (english)
IMS - IP multimedia subsystem - is a standardized network architecture of a new generation which is designed for operators of telecommunications services to provide complex services to mobile and fixed networks. IMS is an architectural framework focused on providing current and future Internet services fixed and mobile users through multi-access IP platform. IMS is defined by a group of standards created by 3GPP (The 3rd Generation Partnership Project) and 3GPP2. IMS enables operators of telecommunications services creation of service infrastructure based on open IP, enabling a fast development of new multimedia communications services combining telecommunications and data services. QoS in telecommunications networks is defined as a set of specific requirements that the network has to fulfil, and which are required to achieve the required functionality of the application (service). Users define the necessary requirements in the form of QoS parameters. The quality of service can be a key to the business market. QoS parameters are necessary to indicate the quality of services or products, and are an important factor in determining the services between different providers. If the prices of similar quality becomes a key factor for the users. The factors that cause degradation of QoS are: congestion, delay, shared communication channels and networks with limited bandwidth with poor management capacity To provide and maintain QoS, resource management must take into account the following parameters: resource availability, resource control and QoS application require
