Patent ID: 7616601

Claim:
A method for providing end-to-end Quality of Service (QoS) within a mobile telecommunication system comprising a Core Network (CN) connected to at least one Radio Access Network (RAN) using Internet Protocol (IP) based transmission, the method comprising the steps of: handling radio resources within the RAN by using a radio resource manager; controlling IP network resources by using a resource map in a Network Resource Manager (NRM) in order to provide said end-to-end QoS, the step of controlling the IP network resources including the steps of the NRM performing path-sensitive call admission control by using the resource map in the NRM, the NRM checking that resources are available along a path, and the NRM pre-allocating resources in an IP network; scheduling resources over time by introducing a start and a stop time as a parameter in a resource request handled by the NRM; communicating resource information between the NRM and the radio resource manager; and reserving the IP network resources along the path by the NRM to fulfill the end-to-end QoS.
