Abstract:
Aspects describe spectrum authorization, access control, and configuration parameters validation. Devices in an ad-hoc or peer-to-peer configuration can utilize a licensed spectrum if the devices are authorized to use the spectrum, which can be determined automatically. Aspects relate to distribution of authorization tickets by an authorization server as a result of validating a device's credentials and services to which the device is entitled. An exchange and verification of authorization tickets can be performed by devices as a condition for enabling a validated wireless link using the spectrum.
Abstract:
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.
Abstract:
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.
Abstract:
Methods, systems, and devices are described for managing a multimedia broadcast multicast service (MBMS). In one configuration, service announcement information for at least one MBMS may be received. At least a subset of the service announcement information may be broadcast in a peer discovery signal. Content of the at least one MBMS may then be relayed to at least one mobile device operating outside a coverage area of a base station. In another configuration, an out-of-coverage status indicator or MBMS query may be broadcast in a first peer discovery signal, and a second peer discovery signal may be received from at least one MBMS relay device. The second peer discovery signal may include at least a subset of service announcement information for at least one MBMS.
Abstract:
Improved group communications methods which are well suited for a wireless environment are described. End nodes request that access nodes make changes in group membership information maintained at the access node. The access node responds to the requests by a response signal indicating a grant or denial of the request. Requests may be to add or remove the end node, e.g., a mobile wireless terminal, from a particular group membership list identified in the request signal. The access node maintains a detailed list of group members and uses the information to control how signals, e.g., packets, are transmitted to the group members. Group membership information may be updated at the access node at the time of handoff and/or an end node enters the cell or otherwise changes its point of network attachment.
Abstract:
Methods, systems, and devices are described for managing wireless communications. In one method, a mobile device may determine to transition to a relay status. The relay status may indicate a capability of the mobile device to function as a relay device between at least one other mobile device and a base station. A peer discovery signal that indicates the relay status may then be transmitted. In another method, a mobile device may broadcast an out-of-coverage status indicator in a first peer discovery signal. A second peer discovery signal may be received from at least one other mobile device. The second peer discovery signal may indicate a capability of the at least one other mobile device to function as a relay device.
Abstract:
Methods, systems, and apparatuses are described for managing a multimedia broadcast multicast service (MBMS). In one configuration, content of an MBMS may be received while operating in a coverage area of a base station. A transition to operate outside the coverage area of the base station may be sensed. A peer discovery signal to request a relay of the content of the MBMS may be transmitted. The peer discovery signal may include an identifier of the MBMS. In another configuration, a first peer discovery signal including an out-of-coverage status indicator for the mobile device or MBMS query and an identifier of an MBMS may be received from the mobile device. A determination may be made regarding whether to relay content of the MBMS. Upon determining to relay the content of the MBMS, a second peer discovery signal indicating a capability to relay the content of the MBMS may be transmitted.

Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in connection with providing private expression protection in a wireless communications network. In one example, a UE is equipped to internally receive a request (e.g., from an application running on the UE) to announce a private expression and/or at least a reference to an expression-code associated with the private expression, and determine whether the reference to the expression-code and/or the expression-code matches a stored instance of the expression-code. In an aspect, the UE may be equipped to announce the at least one of the private expression or the expression-code when stored instance of the expression-code corresponds to the expression-code received with the request. In another aspect, the UE may be equipped to prohibit announcement of any information associated with the private expression when stored expression-code does not correspond to the expression-code received with the request.
