COMMUNICATION METHOD AND GATEWAY APPARATUS

摘要

PURPOSE: A communication method and a gateway apparatus are provided to prevent service quality from being lowered due to delay. CONSTITUTION: A packet is received from a BS(S21). The received packet is decapsulated so that a DP processor extracts a transmission packet transmitted from an MS. A classification processor determines a transmission source address of the extracted transmission packet is matched with a transmission source address of HA access information(S23). A classification place of the transmission packet is determined to determine it is necessary whether to process the transmission source address(S25). A packet is transmitted to an HA(S28).
