Network resource manager in a mobile telecommunication system
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.
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.
2. Method according to claim 1 , wherein the NRM is used within the RAN and the CN.
3. Method according to claim 1 , wherein the NRM is used within the RAN.
4. Method according to claim 1 , wherein the NRM is used within the CN.
5. Method according to claim 1 , the method comprising the further step of signalling resource information between the NRM and at least a second NRM used within at least a second network domain.
6. Method according to claim 1 , the method comprising the further step of monitoring topology changes by using the NRM, retrieving routing information concerning the IP network.
7. Method according to claim 6 , wherein the topology is monitored in order to be able to reallocate the IP network resources.
8. Method according to claim 1 , wherein the path-sensitive call admission control is parameter based.
9. Method according to claim 1 , wherein the path-sensitive call admission control is measurement based.
10.
