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.

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 based on information comprised in the IP packet, 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.
