Abstract: Methods and apparatus for communicating packets from a remote access node assembly by way of a serving access node assembly are described. An inter-route tunneling protocol module which interfaces with a radio link protocol module is used to recover a tunneled route protocol packet. Information to be communicated to the access terminal from the remote access node assembly by way of the serving access node assembly is subject to two levels of radio link protocol (RLP) processing operations. The first level of RLP processing being performed by the remote access node assembly. The second level of RLP processing being performed by the serving access node assembly. The access terminal, in recovering information performs the inverse of the two levels of RLP processing.

Abstract: A mobile user terminal 402 accesses a packet data network 450 through one or more of several network access points 404-412. One or more control points 432-440 determines which network access point or points the user terminal is to access. Control may be retained in the current control point, or transferred to another control point, whenever it is convenient. There are preferably several routers, each having an associated home agent 418-420 which determines which foreign agents need to be accessed on behalf of each user terminal. There are several foreign agents 422-430, which forward packets received from a user terminal's home agent to the control point currently controlling communications with the user terminal.

Abstract: Methods and apparatus for communicating between an access terminal (AT) and remote device via an access point (AP) are described. For communications over the air link, between an AP and an AT a short address corresponding to the remote device is used for routing packets to/from the remote device. This conserves air link resources. However, for communicating between the AP and the remote device a longer address, e.g., a full IP address corresponding to the remote device is used. The AT converts between the long and short addresses as information, e.g., packets are communicated between the remote device and the AT. The long address may be, for example, an IP address corresponding to the remote device used to route packets through a Layer 2 tunnel between the remote device and the AP. In some embodiments the remote device is a remote access point.

Abstract: A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station is in communication with, referred to as an “Active Set”. In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the “Neighbor Set”. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM). The mobile station monitors transmissions from all of the base stations on the active set to receive a handoff direction message (HDM).

Abstract: Embodiments disclosed herein relate to providing dynamic assignment of home agent and home address in wireless communications, such that a mobile node away from home may receive local access services from a visited network. In an embodiment, a mobile node accesses a visited network. The visited network authenticates the mobile node with its home network. The visited network then assigns a visited home agent and a home address for the mobile node. The mobile node subsequently performs secure binding with the visitor home agent. The mobile node proceeds with communications using the visitor home agent and home address.

Abstract: Methods and apparatus for communicating packets of information from an access terminal to a remote access node assembly by way of a serving access node assembly are described. An inter-route tunneling protocol module which interfaces with a radio link protocol module is used to tunnel route protocol packets. A first radio link protocol stream is associated with an application resident on the access terminal. A second radio link protocol stream is associated with an inter-route tunneling protocol module. Information to be communicated to a remote access node assembly by way of a serving access node assembly is subjected to two different radio link protocol processing operations. A first one of the RLP processing operations corresponds to the remote access node assembly while the second RLP processing operation corresponds to the serving access node assembly.

Abstract: A novel key management approach is provided for securing communication handoffs between and access terminal and two access points. This approach provides for securely handing off communications between an access terminal and access point without risking exposure a master key for the access terminal. Temporary master keys are derived for low latency handoffs and secure authentication between a new access point and the access terminal. In one aspect, a distributive key management scheme is provided in which a current access point generates a new security key (based on its own security key) that is used by the next access point with which an access terminal communicates. In another aspect, a centralized key management scheme is provided in which a central authenticator maintains, generates, and distributes new security keys (based on a master security key associated with the access terminal) to access points.
