Verfahren zur Übertragung von IP-Paketen über ein zellulares Mobilfunksystem, und Einrichtungen des zellularen Systems zur Durchführung dieses Verfahrens

摘要

The invention concerns the dynamic reservation of resources according to the RSVP protocol for transmitting an application flow in the form of first packets between a radio terminal and a remote unit interconnected via a first IP network and a cellular radio communication system. The cellular radio communication system uses a second IP network, or even a third IP network, in its core network. According to the invention, the dynamic reservation of resources in the first IP network is completed by a second dynamic reservation of resources in the second IP network, and where necessary a third dynamic reservation of resources in the third IP network. For this, transmission elements of the cellular radio communication system perform the association between the tunnel identity used for transmitting the first packets of the application flow and the parameters assigned to each RSVP session.
