Embodiment Construction

[0047] In the embodiment of the present invention, a two-way tunnel is established between each LMA and the MAG; each LMA automatically checks the load status at a preset time interval, and sends its own load status to the RMS; the RMS receives the load of each LMA The status is stored in the load list maintained by itself; RMS periodically traverses the load list maintained by itself, and adjusts the data forwarding path of MAG in real time according to the load status of each LMA.

[0048] In addition, when the MN switches to the current MAG, after the current MAG completes the standard PBU / PBA exchange, the routing update signaling is forwarded to each LMA via the RMS, and each LMA adjusts the corresponding routing items respectively, and the acquired data of the MN All are forwarded to the current MAG by the tunnel interface.

[0049] Here, the LMA can send its own load status to the RMS through the load information signaling Load_info;

[0050] The forwarding of the rout...

Abstract

The embodiment of the invention discloses a method and system for realizing load balancing and switching of uplink and downlink data of a mobile node (MN). The method includes the following steps that: a bidirectional tunnel is established between each local mobility anchor (LMA) and mobile access gateways (MAG); each local mobility anchor (LMA) automatically checks a load status at preset time intervals and sends the load status of the local mobility anchor (LMA) itself to a route management entity (RMS); the route management entity (RMS) receives the load status of each local mobility anchor (LMA) and stores the load status to a load list maintained by the route management entity (RMS) itself; the route management entity (RMS) traverses the load list maintained by the route management entity (RMS) itself, and adjusts data forwarding paths of the mobile access gateways (MAG) in real time according to the load status of each local mobility anchor (LMA); when the mobile node (MN) is switched to a current mobile access gateway (MAG), the current mobile access gateway (MAG) completes standard proxy binding update (PBU)/proxy binding acknowledgement (PBA) switch, and then, forwards routing update signaling to each local mobility anchor (LMA) through the route management entity (RMS); and each local mobility anchor (LMA) adjusts corresponding routing items respectively and forwards obtained data of the mobile node (MN) to the current mobile access gateway (MAG) through a tunnel portal. The embodiment of the invention also discloses a system for realizing load balancing and switching of uplink and downlink data of a mobile node (MN).

Description

technical field [0001] The present invention relates to load balancing and handover technology in the field of mobile communication, in particular to a method and system for realizing load balancing and handover of uplink and downlink data of a mobile node (Mobile Node, MN). Background technique [0002] At present, in the mobile Internet, due to the various disadvantages brought about by global mobility, such as high signaling overhead and the need to modify the host, the Internet Engineering Task Force (IETF) of the International Standards Organization has proposed a network-based area Mobility Management Protocol Proxy Mobile IPv6 (Proxy Mobile IPv6, PMIPv6). [0003] In the PMIPv6 technology, the network area that handles the mobility management behavior of a MN through the PMIPv6 protocol is called the PMIPv6 domain. In this domain, the core functional entities are Local Mobility Anchor (LocalMobility Anchor, LMA) and Mobile Access Gateway (Mobile Access Gateway, MAG);...
