MULTI-HOMED TERMINALS

摘要

For a multi-homed terminal, a method comprising a step of receiving, from a server, an a multiple interface related routing policy rule defined per terminal, said a multiple interface related routing policy rule comprising flow distribution rules including an Inter-APN flow distribution container that includes information related to routing IP flows with respect to a plurality of APNs for using PDN connections to access multiple IP networks is performed. Then, a first round of rule evaluation according to a flow distribution rule of highest priority selected among the flow distribution rules in the received a multiple interface related routing policy rule is performed. If the selected flow distribution rule is from the Inter-APN flow distribution container, then performing, by the multi-homed terminal, a second round of rule evaluation to select an access technology for performing flow distribution.

1. A method of routing IP flows in a wireless communication system, comprising:
receiving, by a multi-homed terminal from a server, a multiple interface related routing policy rule, said multiple interface related routing policy rule comprising flow distribution rules including an Inter-APN flow distribution container that includes information related to routing Internet protocol (IP) flows with respect to at least one prioritized access point name (APN) for using at least one packet data network (PDN) connection to access at least one IP network, said multiple interface related routing policy rule further comprising 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), and a For Non-Seamless Offload flow distribution container used for Non-Seamless WLAN Offload (NSWO); performing, by the multi-homed terminal, a first round of rule evaluation according to a flow distribution rule selected among the flow distribution rules in the received multiple interface related routing policy rule; and if the selected flow distribution rule is from the Inter-APN flow distribution container, then performing, by the multi-homed terminal, a second round of rule evaluation to select an access technology for performing flow distribution.
