Title (EN) METHOD AND SYSTEM FOR MAPPING MP-GW PORT FOR EACH SERVICE FLOW IN MULTI-PATH ENVIRONMENT

Abstract:
(EN) The present invention relates to a service flow-specific MP-GW port mapping method and system for applying an existing EPC solution (policy and charging rule) to a multi-path aggregation solution which is an MPTCP solution. That is, the present invention may add, in MPTCP traffic between a terminal and an MP-GW, mapping information between an application server and an MP-GW port number and may newly add, to the existing EPC (SAE-GW), a 5-tuple filter for MPTCP traffic matching, so as to perform MPTCP traffic matching without adding a separate hardware device or software function. Therefore, the existing policy and charging rule applied to conventional typical TCP traffic can also be applied to MPTCP traffic.
(FR) La présente invention concerne un procédé et un système d'association de ports de MP-GW spécifiques à un flux de service, visant à appliquer une solution EPC existante (règle de politique et de facturation) à une solution d'agrégation à trajets multiples qui est une solution MPTCP. Autrement dit, la présente invention peut ajouter, dans un trafic MPTCP entre un terminal et une MP-GW, des informations d'association entre un serveur d'applications et un numéro de port de MP-GW et peut ajouter nouvellement, à l'EPC existant (SAE-GW), un filtre à 5 uplets servant à la mise en correspondance de trafic MPTCP, de façon à effectuer la mise en correspondance de trafic MPTCP sans ajouter un dispositif matériel ou une fonction logicielle séparés. Par conséquent, la règle existante de politique et de facturation appliquée à un trafic TCP typique conventionnel peut également être appliquée à un trafic MPTCP.
(KO) 본 발명은 기존의 EPC 솔루션(poliy 및 charging rule)을 MPTCP 솔루션인 다중 경로 병합 솔루션(Multi-Path Aggregation Solution)에 적용하기 위한 것으로서, 서비스 플로우 별 MP-GW 포트 매핑 방법 및 시스템에 관한 것이다. 즉, 본 발명은 단말과 MP-GW 사이의 MPTCP 트래픽에 어플리케이션 서버, MP-GW 포트 번호의 매핑정보를 추가하고 기존의 EPC(SAE-GW)상에 MPTCP 트래픽 매칭용 5-tuple 필터를 새로 추가함으로써, 별도의 하드웨어 장비나 소프트웨어적 기능의 추가 없이 MPTCP 트래픽에 대한 매칭을 수행할 수 있다. 이에 따라 MPTCP 트래픽에도 기존의 일반 TCP 트래픽에 적용된 policy 및 charging rule을 적용할 수 있는 장점이 있다.
