Publication number: 20110255473Abstract: A method, system, and Mobile Access Gateway (MAG) for local routing optimization are provided. After receiving a packet sent from a Mobile Node (MN) to a Correspondent Node (CN), an MAG queries for a binding update entry corresponding to the MN. When an MAG local routing flag is set in the binding update entry, the packet is sent to the CN; and when a Local Mobile Anchor (LMA) local routing flag is set in the binding update entry, the packet is sent to an MAG of the CN. With the present invention, the delay in sending the packet from an MN to a CN is shortened, the communication efficiency is increased and the user experience is improved.Type: ApplicationFiled: June 23, 2011Publication date: October 20, 2011Applicant: Huawei Technologies Co., Ltd.Inventors: Qin WU, Yungui WANG, Jinwei XIA, Xiaoyu GONG
