(57) Abstract :
In a mechanism for controlling a communication connection with policy control, after the communication connection with policy
control is established in a communication network between a user equipment and service providing network element via a network
control element on the basis of an initial packet data protocol context, a modification of the initial packet data protocol context for the
communication connection is requested or initiated at the network control element. When the modification is authorized, relevant
resources for a modified packet data protocol context usable for signalling traffic and transmission of media stream data are set up.
