Abstract

The invention relates to the technical field of service flow distribution, in particular to a route optimization method and system of mobile multicast supported by PMIPv6. The method comprises the steps that a mobile terminal has access to a PMIPv6 domain, and builds network connection with a mobile access gateway, and a route announcement message is sent to trigger the mobile access gateway and an area mobile anchor point / mobile multicast tree anchor point to build a PMIPv6 bidirectional tunnel; a multicast data source sends multicast data to the mobile terminal, wherein the multicast data are firstly sent to a multicast router, and then the multicast data source is forwarded to the mobile terminal through the area mobile anchor point / mobile multicast tree anchor point and the mobile access gateway. The multicast data source in the PMIPv6 domain can directly send the data to the mobile terminal without the multicast router, and therefore large data delay is avoided.

Description

technical field

[0001] The invention relates to the technical field of service flow distribution, in particular to a routing optimization method and system for PMIPv6 supporting mobile multicast. Background technique

[0002] The Proxy Mobile IPv6 (PMIPv6) protocol is a network-based regional mobility management protocol formulated by the IETF. It has the advantages of no terminal support, high handover performance, terminal location privacy, link technology independence, and multi-home support. The combination of any wide-area mobility management protocols such as HIP and MOBIKE can efficiently support terminal mobility in a heterogeneous converged network environment. At present, PMIPv6 has also been implemented in many products of equipment manufacturers, and its actual upgrade and deployment of the operator's core network is also in progress.

[0003] On the other hand, with the wide application of the Internet and the rapid development of wireless communication technol...
