Method for transmitting multicast data based on Proxy Mobile IPv6 during handoff

摘要

The present invention is handed off in the Proxy Mobile IP protocol-based multicast data transmission method that offers first If the mobile terminal is an access router that belongs to its own zone to detect the deviation of the own domain, and transmitting the first access router of the second access router to inform the access router which is adjacent to the context (Context) message; If the second access router receiving the context message, and transmitting the multicast membership report (Report) message to the mobile terminal to a multicast router; And the second access router receives the multicast data from a multicast router, and transmitting the multicast data received by the mobile terminal. Through this, and the mobile terminal reduces the signaling cost can be performed after the handoff, the handoff may be reduced due to the reception of the multicast data is delayed.
