METHOD AND APPARATUS FOR CONTROLLING MULTICAST IP PACKETS IN ACCESS NETWORK
First Claim
1. A method for, in an accessing device of an access network, controlling an IP packet from a user equipment, comprising:
- a. receiving an IP packet from a user equipment;
b. checking said IP packet and determining whether said IP packet is a multicast IP packet that is allowed to pass;
c. in case that said IP packet is a multicast IP packet that is allowed to pass, sending said allowed multicast IP packet in multicast form.

Abstract
The present invention proposes a method for controlling the uplink transmission of the multicast IP packet sourced from the UE in field of IP packet transmission in access network. According to the technical solution of the present invention, the access devices receives IP packet from the UE, checks the IP packet and determines whether the IP packet is multicast IP packet that is allowed to be accessed. If the access device determines that the IP packet is multicast IP packet that is allowed to be accessed, then it sends the multicast IP packet in multicast form. Via the present invention, the access device can allow the uplink valid multicast IP packet to pass, preferably, determines and intercepts the malicious attacks via multicast IP packet, so as to ensure the DSL access device'"'"'s support for mobile IPv4, so as to keep the uninterrupted connection of the service to the user when the user moves between different subnets.
