METHOD AND SYSTEM FOR RECEIVING MULTICAST DATA IN TUNNELLING-BASED MOBILITY NETWORK ARCHITECTURE, AND MOBILE TERMINAL THEREOF

摘要

Disclosed are a method and a system for receiving multicast data without using a tunnel in a tunneling-based mobility network architecture, and a mobile terminal thereof. By providing a method for receiving multicast data in a tunneling-based mobility network architecture receiving multicast data over a multicast-enabled Internet protocol (IP) network by switching a path before tunneling and thereby transmitting a corresponding channel reception request message to a corresponding visit network when a transmission packet of a mobile terminal is a channel reception request message in a heterogeneous visit network, and at the same time, guaranteeing mobility of the mobile terminal by tunneling a corresponding transmission packet to a care-of-address of a visit network being currently visited when the transmission packet is not the channel reception request message, there are provided a method and a system for receiving multicast data via a visit network without using an existing tunnel.
