|Title:||METHOD AND SYSTEM FOR MAPPING MP-GW PORT FOR EACH SERVICE FLOW IN MULTI-PATH ENVIRONMENT|
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.
