INTER-APN ROUTING FLOW DISTRIBUTION

摘要

For Inter-APN routing flow distribution, a step of receiving, by a UE from a server, an Inter-System Routing Policy (ISRP) rule that comprises flow distribution rules for at least one of a For Flow Based flow distribution container used for IP Flow Mobility (IFOM), a For Service Based flow distribution container used for Multi-Access PDN Connectivity (MAPCON), a For Non-Seamless Offload flow distribution container used for Non-Seamless WLAN Offload (NSWO), and an Inter-APN routing flow distribution container, is performed. Here, the Inter-APN routing flow distribution container comprises information related to routing IP flows with respect to a plurality of APNs for using PDN connections to access multiple IP networks. Then a step of selecting, by the UE, among active/valid flow distribution rules in the received ISRP rule, a flow distribution rule having highest priority is performed.

1. A method of routing IP flows in a wireless communication system, comprising:
receiving, by a UE from a server, a multiple interface related routing policy rule that comprises flow distribution rules for a For Flow Based flow distribution container used for IP Flow Mobility (IFOM), a For Service Based flow distribution container used for Multi-Access PDN Connectivity (MAPCON), a For Non-Seamless Offload flow distribution container used for Non-Seamless WLAN Offload (NSWO), and an Inter-APN routing flow distribution container, wherein the Inter-APN routing flow distribution container comprises information related to routing IP flows with respect to at least one prioritized APN for using at least one PDN connection to access at least one IP network; and selecting, by the UE, a flow distribution rule according to the received multiple interface related routing policy rule.
