    摘要: Methods and apparatus for a configurable architecture with a converged coordinator are described. The converged coordinator may have multiple radio transceivers or interfaces. The converged coordinator may communicate with a plurality of clusters or Personal Area Networks (PANs). The converged coordinator may include a protocol stack with a Convergence Layer and a Converged Medium Access Control (MAC) layer. The converged coordinator may perform channel switching to allow devices to switch from one channel to another (or from one PAN to another). The method may include active channel switching, passive channel switching, and group-based channel switching, as well as two-step active channel switching and one-step active channel switching. The converged coordinator may perform channel switching due to increased congestion or traffic in a particular cluster or PAN. The method may include new messages and fields within messages for use in channel switching.

    摘要: Method and apparatus for supporting machine-to-machine (M2M) communications in a hierarchical network architecture including an M2M gateway are disclosed. An M2M entity, (such as M2M device, M2M gateway, or M2M network entity), may perform a service capability discovery procedure to discover an M2M service capability entity that may provide an M2M service capability, and register with the discovered M2M service capability entity. The address or identity of the service capability entity may be pre-configured or obtained from the dispatcher server. The M2M entity may indicate a support M2M service identifier and receive an identity or address of the M2M service capability entity mapping the service identifier. The gateway may advertise M2M service identifiers supported by the gateway so that the M2M device may access the gateway if there is a match. The address of M2M service capability entities may be obtained from the core network.

    摘要: RFID readers and methods for adjusting a query command slot-count parameter Q for use by radio frequency identification (RFID) tag reader in an RFID tag inventory round are provided. A method for adjusting a query command slot-count parameter Q for use by an RFID tag reader includes setting an initial value for Q for a first inventory round, issuing a query command to a population of RFID tags, and monitoring replies from the population of RFID tags. The value of Q is decreased by a first amount if no reply is received, and the value of Q is increased by a second amount different from the first amount if a tag collision reply is received.

    摘要: A method and apparatus are described for accessing services affiliated with a service provider. A first discovery procedure may be performed to discover at least one service provider, and a bootstrap procedure may be performed with the at least one discovered service provider. A second discovery procedure may then be performed to determine available service capability layers (SCLs) supported by the at least one discovered service provider. The first discovery procedure may include transmitting a service provider discovery request including information for querying a record database to determine matching service provider discovery records, and receiving a service provider discovery response including a service discovery function record list that matches queries in the service provider discovery request. At least one service provider from the service discovery function record list may be selected to bootstrap with. Various versions of the second discovery procedure are described.

    摘要: A method and apparatus for data transmissions in a wireless network are disclosed. A first device may send a first frame to a second device including information regarding a number of pending data frames to be transmitted from the first device to the second device. The first device receives an acknowledgement frame including a number of approved data frames for transmission from the first device to the second device. The first device then may send a plurality of data frames without performing the contention-based channel access procedure in response to the acknowledgement frame. The first device may send a first frame to a second device for requesting data frames that are pending at the second device. The first device receives an acknowledgement frame including a number of pending and approved data frames. The first device may receive a plurality of data frames in response to the acknowledgement frame.
