1. 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.

Abstract
The present invention relates to a method and arrangement for providing end-to-end Quality of Service within a mobile telecommunication system. The communication system comprises at least one network e.g. a Core Network (CN) and at least one Radio Access Network (RAN) for Internet Protocol (IP) based transmission, wherein a Network Resource Manager (NRM) comprising a resource map is monitoring and/or controlling resources within the IP network.

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

19. A Network Resource Manager (NRM) within a mobile telecommunication system that includes a Core Network (CN) connected to at least one Radio Access Network (RAN) using Internet Protocol (IP) based transmission and a radio resource manager that controls radio resources within the RAN, the NRM comprising:
-
a resource map; means for controlling IP network resources within an IP network using the resource map in order to provide feedback to a network operator, said means for controlling comprising means for the NRM performing path-sensitive call admission control by using the resource map in the NRM, for the NRM checking that resources are available along a path, and for the NRM pre-allocating resources in the IP network part of the mobile telecommunication system; means for scheduling resources over time by introducing a start and a stop time as a parameter in a resource request; means for communicating resource information between the NRM and the radio resource manager; means for reserving the IP network resources along the path by the NRM; and means for providing the feedback to the network operator. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
