Problems solved by technology

Therefore, the available bandwidth of a connection is only limited by the physical bandwidth provided by the corresponding interface, and it is impossible to combine the bandwidth belonging to different interfaces in a multi-interface MN, which will inevitably lead to a decrease in bandwidth utilization.

Embodiment Construction

[0025] In order to express the purposes, technical solutions and advantages of the embodiments of the present invention more clearly, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0026] In the embodiment of the present invention, by scheduling at the LMA, full utilization of the bandwidth provided by the multiple interfaces of the mobile node is realized. Specifically, the LMA changes the original binding of an interface to a MAG to binding of an interface to a set of MAGs by extending the MAG proxy binding update method. In the MAG set, each MAG can be set as a default MAG and a standby MAG respectively. When it is necessary to send data to the MN, the LMA can select a suitable MAG from the above collection based on flow ID (flow ID) and other methods.

[0027] figure 1 It is a schematic flowchart of a data forwarding method in PMIPv6 according to an embodiment of the present ...

Abstract

The embodiment of the invention discloses a data forwarding method, a data forwarding device and a data forwarding system in a proxy mobile internet protocol version 6 (Proxy Mobile IPv6, PMIPv6). The method comprises that: a local mobile anchor (LMA) binds at least one interface of a multi-interface mobile node (MN) to a mobile access gateway (MAG) set comprising at least two MAGs; and the LMA selects an MAG from the MAG set according to the preset strategy and interacts data with at least one interface of the multi-interface MN by the selected MAG. In the embodiment, a plurality of MAGs corresponding to a plurality of interfaces can forward data at a certain interface simultaneously so as to merge the bandwidth belonging to different interfaces in the multi-interface MN. Moreover, the invention is simple and practicable, and has high practicability and expandability.

Description

technical field [0001] The present invention relates to the technical field of proxy mobile Internet protocol version 6 (Proxy Mobile IPv6, PMIPv6), more specifically, the present invention relates to a data forwarding method, device and system in PMIPv6. Background technique [0002] With the rapid development of wireless communication technology, users can access the Internet through a variety of networks, including General Packet Radio Service (General Packet Radio Service, GPRS), Long Term Evolution (LongTerm Evolution, LTE), Ultra-Wideband (Ultra-Wideband, UWB ), World Interoperability for Microwave Access (WiMax), wireless broadband (Wifi), ZigBee, etc. [0003] Since various networks have their own strengths and weaknesses, they will co-exist and develop together for a long time, which brings the need for multiple connections of terminals. Terminals can use multiple connections to obtain the technical characteristics and service coverage of multiple networks at the sa...
