Abstract
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.
Claims17
A method for local routing optimization, the method comprising:
- establishing a binding update entry corresponding to a Mobile Node (MN) and a Correspondent Node (CN) ;
- receiving a packet sent from the MN with a destination address of the CN;
- querying for the binding update entry corresponding to the MN and the CN, and acquiring a local routing flag in the binding update entry;
- when the local routing flag in the binding update entry is a Mobile Access Gateway (MAG) local routing flag MAGLocalRouting, sending the packet to the CN;
- and
- when the local routing flag in the binding update entry is a Local Mobile Anchor (LMA) local routing flag LMALocalRouting, sending the packet to an MAG of the CN.
A Mobile Access Gateway (MAG) comprising:
- a receiving module, configured to receive a packet sent from a Mobile Node (MN) with a destination address of a Correspondent Node (CN);
- a query module, configured to query for a binding update entry corresponding to the MN and the CN;
- and
- a sending module, configured to send the packet to the CN, when a local routing flag in the binding update entry is an MAG local routing flag MAGLocalRouting;
- and send the packet to an MAG of the CN, when the local routing flag in the binding update entry is a Local Mobile Anchor (LMA) local routing flag LMALocalRouting;
- wherein the binding update entry corresponding to the MN and the CN is generated by a second generation module.
A system for local routing optimization, the system comprising a first Mobile Access Gateway (NAG) and a Local Mobile Anchor (LMA) wherein
- the first MAG is configured to establish a binding update entry of a Mobile Node (MN) and a Correspondent Node (CN) ;
- receive a packet sent from the MN with a destination address of the CN;
- query for the binding update entry corresponding to the MN and the CN, and acquire a local routing flag in the binding update entry;
- when the local routing flag in the binding update entry is a MAG local routing flag MAGLocalRouting, send the packet to the CN;
- and when the local routing flag in the binding update entry is a LMA local routing flag LMALocalRouting, send the packet to an MAG of the CN;
- and
- the LMA is configured to send the local routing flag to the first MAG.
