Providing QOS in 3G-WLAN environment with RSVP and DIFFSERV
Here we present the end-to-end QoS mechanism in 3G-multiaccess network environment. As multi-access wireless WLAN and wired xDSL wideband multi-access technologies has emerge and become more popular a need for interoperability with different technologies and domains has become necessity. There is also a need for end-to-end QoS management. We show a scenario where the UE-GGSN connection is covered by RSVP and RAN network part uses partial over dimensioning and real-time controlled ATM queuing. DiffServ covers WLAN-Core QoS and radio interface between WLAN AP and WLAN UE uses IEEE's 802.11e. Our interest is to find out how well 3G traffic classes can survive in different traffic conditions in…
Case study for 3G/UMTS services and billing methods
The 3G/UMTS-networks and services will provide a wide range of telecommunication services. To achieve, this, we need a new view to networks, network services and service abilities. The amount of service providers in the 3G networks will be at least the same than in the present Internet. The amount of users in the 3G networks will overgrow the user amount of Internet forming a global worldwide communication society. This paper discusses customer billing in the 3G world. There are some main issues that are not very, clear to all 3G service and network providers, which however, should be settled before, 3G networks are operational. One of the most important matters is the QoS (Quality of Servi…
Control and management of multi-access wireless networks
Eero Wallenius tutki väitöskirjassaan langattomiin monipääsy- ja monipalveluverkkoihin liittyviä kysymyksiä. Hän selvitti 3/4G ja WLAN -verkkojen palvelun laadun laskutuksen säätöä ja hallintaa sekä esitti laskutus- ja säätömalleja analyysien ja simulointien avulla.Palvelun laadun ja laskutuksen suhdetta on jo aikaisemmin tutkittu. Tutkimuksen tulokset ovat helposti sovellettavissa langattomiin 3/4G ja WLAN -verkkoihin. Wallenius tutki myös tilaajan hyväksymissuhdetta palvelun hinnoitteluun. Hän esitti operaattorien tarpeisiin luodun hallintamallin verkkopalvelujen hinnoitteluun ja käyttöön verkon kuormituksen säädöllä. Hän loi myös dynaamisen mallin verkkopalvelujen hinnoittelun optimointi…
