The present invention relates to a methods and network nodes for controlling resources of a service session in a communication network as well as to a corresponding system and computer program to improve the handling of resources in the network, and particularly to optimize signaling in the network. The method for controlling resources for a service session by a policy and charging system in a communication network comprises the steps of obtaining, at a first network node, a request including service session data indicating the type of service; determining, based on the service session data obtained at said first network node, a resource type to be assigned to said service; and sending to a second network node an indication of said resource type assigned to said service, according to which resource type it is determined when a service session associated with said service is terminated. |
