摘要:
Methods and apparatus for generating, communicating, and/or verifying ownership of expressions are described. Various embodiments are well suited for use in a wireless peer to peer communications systems in which expressions are communicated, e.g., broadcast, in discovery intervals. A first communications device generates an expression from a first public key and an additional input, said first public key corresponding to a private key known to said first communications device. The first device transmits the generated expression on a communications channel used for discovery. A second communications device receives the transmitted expression from the first device. The second device transmits a request signal to the first device associated with the expression; and receives from the first device a signed communication signed using a private key known to said first communications device. The second device uses information from the signed communication to determine if said first communication device owns said expression.

Aspects describe enabling two peers that have already paired together under some circumstances to re-identify themselves under different circumstances so that the peers can bypass performing another pairing only to discover that they are already paired. A Bloom filter is constructed from an available pool of locally selected identifiers and is sent to a peer node in a first message. Upon receiving the message with the Bloom filter, peer node checks all its known identifiers. If peer node finds that one of its identifiers is a member of the Bloom filter, peer node sends a reply in order to achieve a mutual identification.

Methods and apparatus related to selecting advertisements for presentation based on, e.g., received signals from devices in the proximity to a user's communications device, are described. In various embodiments a mobile device monitors for signals, e.g., peer discovery or other signals, from other devices which transmit, e.g., broadcast, advertisement related information. In various embodiments a device receives advertising information from an advertising device, e.g., AdPoint. In the case of peer to peer signaling, the AdPoint may be in close proximity to the user device receiving the advertising information. Advertising information received from devices in proximity to the user device are used in selecting an advertisement for presentation. Distance from the user device to the AdPoint transmitting an advertisement or advertisement identifier, distance to a store to which an advertisement relates, and/or distance to a location to which an advertisement relates, are taken into consideration when selecting an advertisement for presentation.

An apparatus, a method, and a computer program product of a wireless device are provided in which a first device identifier of a wireless device is provided. An allocation record is received that includes an expression used for discovery, a second device identifier, and at least one of a digital signature of a first server that delegates the expression or a digital signature of a second server that manages the expression. The allocation record is verified. An apparatus, a method, and a computer program product of a first server are provided in which a device identifier is received from a wireless device. An allocation record is generated that includes an expression used for discovery, the device identifier, and at least one of a digital signature of the first server or a digital signature of a second server that manages the expression. The allocation record is sent.

Methods and apparatus relating to ad cache maintenance, e.g., determining when ad cache replenishment should occur, replenishing ad cache content and/or updating the content of an ad cache, on a device which supports the presentation of advertisements (ads) are described. Signals are received by a first device including an ad cache. The signals are received from other devices, e.g., devices in the direct wireless communications range of the first device. Received signals are processed and provide context information, e.g., information about the surrounding, services available, stores in the region, etc., in which the first device receiving the signals is at a given point in time. Context information is stored. As new context information is generated from received signals the newly generated set of context information is compared to a previously generated set of context information. Changes in context information are detected and used in performing ad cache maintenance operations.

A method, a computer program product, and an apparatus are provided. The apparatus may be equipped to obtain one or more application identifiers from one or more applications on a wireless device, generate a super identifier (SID) having elements corresponding to the one or more applications and a base that identifies one or more common properties of the one or more applications, and broadcast the SID during one or more peer discovery slots allocated for the wireless device. In another example, a UE may be equipped to receive the SID broadcast by another UE, determine a match between at least one of the one or more common properties in the base, and determine whether an element associated with one or more applications is present in the SID.
摘要:
The claimed subject matter relates to providing appropriate QoS treatment to one or more traffic flows associated with a terminal, wherein the QoS treatment is defined within a profile assigned to the terminal and implemented when the terminal requests access to a network. An access mode can receive identifying indicia associated with the terminal and relays such indicia to an authentication and authorization server (AAS). The AAS can thereafter provide the access node with a profile that defines QoS treatment to associate with one or more traffic flows related to the terminal.
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.
