Claim:
1. A method in a node in a core network, for informing a node in a Radio Access Network, RAN, about a type of service associated with an IP packet to be delivered to the node in the RAN, the method comprising: receiving the IP packet from a packet data network, the IP packet having an IP header comprising an original Differentiated Services Code Point, DSCP, value; determining a type of service associated with the IP packet by one of Deep Packet Inspection, DPI, on the received IP packet or by header inspection of the IP header; determining a second DSCP value based at least partly on the type of service of the IP packet; adding the determined second DSCP value to the IP header of the IP packet; and forwarding the IP packet to the node in the RAN, to subsequently be delivered to a destination terminal, thereby enabling the node in the RAN to identify the type of service based on the second DSCP value for further processing of the IP packet when delivering the IP packet to the destination terminal.
