The invention relates to a method for the transfer of policy control information during handover in a communication system. A session between a terminal and a remote node via a first network node has been established previously. The session comprising media components transmitted via the first gateway using first media component bearers. A handover condition is detected and a signaling connection is established between the terminal and the second gateway. Information on a second network node is obtained by the terminal, which determines if a proxy for the session has changed. If it has, information on media components is sent to a policy decision entity associated with the second network node. The policy decision entity authorizes second media component bearers with the information provided. Finally, the second media component bearers are established between the terminal and the second gateway. |
