    摘要: Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.

    摘要: Aspects relate to allowing peer nodes that establish a communication through a home agent to move that session to a directly connected link. Thus, the directly connected nodes can exchange packets natively without encapsulation. Further aspects allow a node that does not have any home agent entity to switch from a local network to a global network without losing ongoing sessions.

    摘要: Techniques for supporting policy control and charging (PCC) functions in a wireless communication network are described. In one design, a Policy Control and Charging Rules Function (PCRF) may receive a request from a first network entity (e.g., a home agent) to establish a PCC session for a user equipment (UE) accessing the first network entity using a mobility protocol (e.g., Mobile IP). The PCRF may determine the mobility protocol used by the UE based on an IP-CAN Type parameter included in the request. The PCRF may determine PCC rules for the PCC session based on the mobility protocol and may send the PCC rules to the first network entity. The first network entity may apply the PCC rules on packets for the PCC session and may count each packet for charging. A second network entity may forward the packets but would not count these packets for charging.

    摘要: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

    摘要: Methods and apparatus for generating, communicating, and/or using sets of addresses corresponding to a communications device are described. A first communications device generates, from a public key and a random number, both a first address and a second address. The generated address pair is communicated to a second communications device along with proof of ownership information regarding the address pair via an address signaling message such as a binding update message. The second communications device processes the received address signaling message and determines address pair validity and/or address pair ownership information. The first address may be associated with a first network, e.g., an unsecure WAN network, while the second address may be associated with a second network, e.g., a secure peer to peer network. Decisions on switching between using the first address to using the second address may be based on address validity and/or address ownership determinations.
