Abstract
A media access gateway comprises a wireless network interface, an authorization module, a filter information module, and a proxy mobility agent module. The wireless network interface selectively establishes a wireless link with a first interface of a wireless terminal that has a plurality of wireless interfaces. The authorization module determines a home agent corresponding to the wireless terminal. The filter information module receives filter information from one of the wireless terminal and a server and generates output filter information. The proxy mobility agent module transmits a binding update to the home agent. The binding update includes the output filter information.
Claims19
A media access gateway comprising:
- a wireless network interface that selectively establishes a wireless link with a first interface of a wireless terminal that has a plurality of wireless interfaces;
- an authorization module that determines a home agent corresponding to the wireless terminal;
- a filter information module that receives filter information from one of the wireless terminal and a server and generates output filter information;
- and
- a proxy mobility agent module that transmits a binding update to the home agent, wherein the binding update includes the output filter information.
A method comprising:
- selectively establishing a wireless link with a first interface of a wireless terminal that has a plurality of wireless interfaces;
- determining a home agent corresponding to the wireless terminal;
- receiving filter information from one of the wireless terminal and a server;
- generating output filter information based on the filter information;
- transmitting a binding update to the home agent, wherein the binding update includes the output filter information;
- receiving the binding update;
- storing an entry corresponding to the wireless terminal in a binding cache, wherein the entry includes the output filter information;
- selectively forwarding packets based on the output filter information;
- selectively establishing wireless links between the plurality of wireless interfaces of the wireless terminal and a plurality of media access gateways;
- storing filter information for each of the plurality of wireless interfaces;
- and
- transmitting filter information for one of the plurality of wireless interfaces to one of the plurality of media access gateways when the one of the plurality of interfaces establishes a wireless link with the one of the plurality of media access gateways,
- wherein the filter information is transmitted in a message that requests a Layer 3 address from the one of the plurality of media access gateways.
