METHOD FOR INFORMING A NODE IN A RADIO ACCESS NETWORK (RAN) ABOUT A TYPE OF SERVICE ASSOCIATED WITH AN IP PACKET.

摘要

A core network node for informing a node in a RAN about a type of service associated with an IP packet to be delivered to the node in the RAN, and a RAN node for delivering a received packet to a terminal are provided. The core network node receives the IP packet from a packet data network, the IP packet having an IP header comprising an original DSCP value, and determines a type of service associated with the packet. The core network node determines a second DSCP value based at least partly on the type of service of the packet, and adds the determined second DSCP value to the header. The core network node forwards the IP packet to the RAN node, to subsequently be delivered to a destination terminal. Thereby the RAN node is able to identify the type of service based on the second DSCP value for further processing of the packet when delivering the IP packet to the destination terminal.
