Abstract: This invention relates generally to a method of associating an IP address with a link layer address in a wireless communication network. The method comprises the steps of assigning an IP address to a plurality of link layer addresses; establishing a link layer connection with a first wireless network interface on the IP address; and establishing a link layer connection with a second wireless network interface on the IP address. The method of the present invention enables the increased downloading of data to a client device by aggregating data links associated with an IP address. The method also enables the bi-casting of data to a client device from an IP address associated with a plurality of link layer addresses of wireless communication device. Finally, the invention enables failure recovery by enabling downloading to a second link layer address if a communication link to a first link layer address deteriorates.

Abstract: The present invention provides network-layer authentication protocols for authenticating mobile client and access router to each other. The present invention uses Router Discovery as a carrier to implement the authentication protocols. In an embodiment of the present invention, a mobile client sends out a solicitation message to request connectivity service. The solicitation message contains a proof of identity of the mobile client. An access router that receives the solicitation message will not respond to it until the proof of the identity is verified. Only when the proof of identity of the mobile client is verified, will the access router respond and return an advertising message to the mobile client, thereby preventing unauthorized mobile clients from obtaining network access.

Abstract: A method of connecting a client device with a router in a wireless communication network is disclosed. The method comprises the steps of establishing a link layer connection with a first access point with a first wireless network interface; detecting a second access point with a second wireless network interface; establishing a link layer connection with a second access point with a first wireless network interface; and determining the compatibility between the client device with an access router associated with the second access point.

Abstract: A link-layer trigger protocol for data communication between a client and a wireless access device. A client is connected to a wireless access device, where the client and the wireless access device are operable to communicate with one another using a link-layer trigger datagram. The link-layer trigger datagram includes an IP header, a UDP header and a link-layer trigger header.
