摘要:
Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal.

In an ad hoc peer-to-peer type network during peer discovery, information relating to an identifier associated with users of various devices is broadcast to other devices in an efficient manner. Two or more identifiers can be processed to produce a single value (e.g., bit vector) that is transmitted for the purpose of peer discovery, thus mitigating the need to broadcast the two or more identifiers separately. A public identifier can be converted to a private temporary identifier and the private temporary identifier can be used as one of the inputs to the operation producing the single value to be transmitted. The aspects are not limited to peer discovery and can include broadcasting by inanimate objects or broadcasting of services, functions or interests.

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.

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.

The claimed subject matter relates to performing quality of service management in a mobile wireless communications system. In more detail, in some wireless environments a wireless terminal can be connected to multiple access nodes by way of links, and the wireless terminal can move between various access nodes changing its points of attachment to the network, including its primary point of attachment. Requesters of resources with respect to the wireless terminal can be notified when the primary point of attachment alters, such that subsequent requests are provided to a correct access node (e.g., base station).

Providing for secure tracking and reporting of wireless resources utilized by a mobile device is described herein. By way of example, resources utilized in conjunction with network-facilitated or peer-to-peer wireless data exchange can be tracked in secure, tamper-resistant components of the mobile device. Further, a report can be compiled from the tracked information and digitally signed with a secret data/material specific to the mobile device. The signed report can be submitted to a network server in conjunction with accounting, billing or like functions. By validating the signature of a mobile device, the network server can trust that information collected and submitted by user devices has not been tampered with or spoofed with an ID of another such device.

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.

Methods and apparatus related to broadcasting data in a peer to peer wireless communications network are described. A timing structure is utilized employing slots of a first type which support broadcast traffic transmissions and unicast traffic transmissions and slots of a second type which support unicast traffic transmission but do not support broadcast traffic transmissions. In various embodiments, traffic air link resource scheduling is performed in a decentralized manner on a slot by slot basis. In some such embodiments, a wireless device prior to transmitting a broadcast data traffic signal, transmits a broadcast transmission request signal, sometimes alternatively referred to as a broadcast indicator signal; and a wireless device prior to transmitting a peer to peer unicast signal, transmits a peer to peer traffic transmission request signal. In various embodiments, for slots of the first type, broadcast transmission requests have priority over peer to peer unicast transmission requests.
