Patent ID: 7911943

Claim:
A method comprising: causing establishment of a communication connection with a 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, wherein the initial packet data protocol context comprises a signaling packet data protocol context; causing receipt of a request 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 in an instance in which 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, setting up relevant resources comprising setting up packet classifier filters for a media stream to be transmitted via the communication connection in parallel to signaling filters for the signaling packet data of the initial packet data protocol context, and facilitating responding to the request for modification with an acknowledgement or with a set of communication connection parameters resulting from setting up the relevant resources.
