Embodiment Construction

[0027] Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. The following specific embodiments are only used to illustrate the content of the present invention, and are not intended to limit the present invention.

[0028] figure 1 It is a system configuration diagram showing a multicast fast switching system according to an embodiment of the present invention. Such as figure 1 As shown, the multicast fast handover system includes multiple MAGs (Mobile Access Gateways) 11-14, LMA (Local Mobility Anchor) 2, core network 3, mobile node 4 and base station 5. Among them, the definitions of MAG11-14, LMA2, mobile node 4 and base station 5 are the same as those of the proxy mobile IPv6 protocol. LMA2 is the home agent of the mobile node and is connected through the core network 3 . Multiple MAG1s are connected to each LMA2, and the MAG1 manages the IP mobility of the mobile node and sends mobility-related signa...

Abstract

The present invention provides a mobile access gateway, a multicast fast switching system and a multicast fast switching method for realizing multicast fast switching, which can reduce switching delay and data loss during multicast switching without causing waste of network resources And increase the load of mobile access gateway and network. The mobile access gateway includes: a network interface unit; a handover initiation message processing unit; a handover reply message processing unit; a handover initiation message construction unit; Constructing a handover initiation message, and calling the network interface unit to send the handover initiation message; after receiving the handover initiation message, controlling the handover initiation message processing unit to process the handover initiation message; after receiving the handover reply message, controlling the handover initiation message processing unit The handover reply message processing unit processes the handover reply message.

Description

technical field [0001] The present invention relates to a mobile access gateway for realizing multicast fast switching, a multicast fast switching system and a multicast fast switching method, in particular to a mobile access gateway for realizing multicast fast switching in a proxy mobile IPv6 system, The multicast fast switching system and the multicast fast switching method can reduce switching delay and data loss during multicast switching without causing waste of network resources and increasing the load of the mobile access gateway and the network. Background technique [0002] In recent years, multicast (multicast) technology has been increasingly widely used. Among various IP technologies, by using IP multicast technology to transmit data, single-point transmission and multi-point reception can be realized with minimum overhead, thereby greatly saving network bandwidth and reducing network load. [0003] For example, the multicast technology is widely used in the Pr...
