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.

Method of controlling a communication connection with policy control, the method comprising steps of:
- establishing the communication connection with the policy control in a communication network between a user equipment and service providing network element via a network control element based on an initial packet data protocol context;
- requesting for a modification of the initial packet data protocol context for the communication connection at the network control element;
- checking whether or not the modification is authorized;
- and
- when the modification is authorized,
- setting up relevant resources for a modified packet data protocol context configured to signal traffic and transmission of media stream data, and
- responding to the request for modification with an acknowledgement or with a set of communication connection parameters resulting from the step of setting up the relevant resources.
System for controlling a communication connection with policy control, the system comprising
- a user equipment;
- a network control element;
- and
- a service providing network element;
