    摘要: Methods and apparatus related to the determination of the trustworthiness of information communicated in a message and/or the exchange of trust information are described. Various described methods and apparatus are well suited to peer to peer wireless communications in an ad-hoc network. At a given time, a communications device may have a trust relationship with a first set of devices. A first communications device determines trustworthiness of a received message from a second device, which is not a member of the first set of devices, based on information received from a third device which is a member of the first set of devices. The first communications device makes an informed decision as to whether or not to act upon the first message based upon its trustworthiness determination.

    摘要: Embodiments describe synchronizing access routers with wireless terminal state information. According to an embodiment is a wireless terminal that transmits a message that includes an address for at least two access routers. State change information can optionally be included in the message. According to another embodiment is an access router that receives a state change notification from a wireless device or another access router. The state change notification is updated in the access router. An acknowledgment confirming the updated state change may be sent to the wireless terminal. Dynamic state synchronization is provided with minimal communication with wireless terminal.

    摘要: Methods and apparatus related to routing in communications networks are described. Various embodiments are well suited to wireless communications systems lacking centralized control, e.g., a mobile wireless communications system supporting the dynamic formation and/or maintenance of overlapping peer-to-peer ad hoc networks. A node can establish multiple links, e.g., with different links corresponding to different overlapping networks. Next hop packet routing information, e.g., forwarding tables, are maintained on a per network basis. A node determines the next hop routing for a received packet to be forwarded based on the link upon which the packet was received, which is associated with a particular network, and the included packet destination address. The same destination address may, and sometimes does, correspond to different next hop nodes for different networks.

    摘要: The claimed subject matter relates to assigning a home agent to a wireless terminal during authentication, authorization, and/or accounting with respect to the wireless terminal. The wireless terminal can provide identifying indicia which can be relayed to a AAA server by way of a base station. The AAA server can then determine one or more home agents that can be associated with the wireless terminal. If more than one home agent can be assigned to the wireless terminal, the base station can resolve which home agent to utilize during registration of the wireless terminal. Such determination can be important with respect to MVNOs.

    摘要: The invention described herein enables a form of downlink macro-diversity in packet-switched cellular networks. It allows packets to be selectively delivered from a network/internetwork to an end node, e.g., a wireless communication device or terminal, over a set of available link-layer connections to/from the end node, through one or more access nodes, e.g., base stations. Downlink macro-diversity is particularly important when the link-layer connections between the end node and the corresponding access node, e.g., the access links, are subject to independent or partially correlated time variations in signal strength and interference. In accordance with the invention, the end node dynamically selects the downlink to be used out of a set of available access links on a per packet basis subject to prevailing channel conditions, availability of air-link resources and other constraints. The invention improves the robustness and efficiency of communication, overall utilization of air-link resources, and quality of service experienced by the end node.

    摘要: The claimed subject matter relates to performing routing in a wireless communications system. In more detail, each device associated with a wireless packet-switched network may not be aware of an identity and/or address of a particular point of attachment with respect to a wireless terminal. A data packet that should be provided to a particular point of attachment can be initially directed to a wireless terminal or a one-hop multicast address, for instance. Thereafter, the data packet can be encapsulated in a frame format and identity of the particular point of attachment can be provided in such frame. The frame can thereafter be routed to the point of attachment.
