A wireless mesh network includes a mesh of continuously-powered devices (CPDs) and a mesh of battery-powered devices (BPDs). The BPDs are organized into hop layers based on hopping distance to the mesh of CPDs. In a medium latency communication mode, a given BPD receives data during a receive window that is scheduled to occur within either the first half of a communication window or the second half of the communication window, depending on the parity of the hop layer where the BPD resides. With this approach, a data packet can traverse one hop of the BPD mesh per communication window. In a low-latency communication mode, a given BPD receives and transmits data according to an alternating pattern that depends on the parity of the hop layer where the node resides. With this technique, a data packet can traverse multiple hops of the BPD mesh within a single communication window. These techniques also are applicable to CPDs and other types of nodes as well.

An SCEF entity (10) according to the present invention includes a storage unit (11) configured to buffer first Non-IP data not delivered to a communication terminal (40), and a control unit (12) configured to, when the first Non-IP data is buffered upon receiving second Non-IP data addressed to the communication terminal (40) from a server device (30), suppress transmission of the second Non-IP data to a control device (20) in a mobile network and buffer the second Non-IP data into the storage unit (11).

A method and apparatus are disclosed to manage the enhanced medium access control-e (MAC-e) and enhanced MAC-es resources and respective variables for the enhanced dedicated channel (E-DCH) in the enhanced Cell_FACH state. Due to the nature of the E-DCH transmission in the uplink (UL) in the Cell_FACH state and the fact that a wireless transmit/receive unit (WTRU) might set up and release the E-DCH resources more frequently, methods to deal with the TSN numbering are described.

A computer device may include a memory storing instructions and a processor configured to execute the instructions to select a broadcast method for a wakeup signal for a wireless communication device; instruct a base station to broadcast the wakeup signal using the selected broadcast method; and provide information identifying the selected broadcast method to the wireless communication device. The processor may be further configured to receiving a wakeup request from a machine-type communication interworking function (MTC-IWF) device; map the received wakeup request to a wakeup signature beacon signal associated with the wireless communication device; and instruct the base station to transmit a wakeup signature beacon signal to the wireless communication device based on the received wakeup request.

A mobile device that comprises a main receiver and a wake-up receiver is operated by periodically attempting to receive a first signal that is configured for receipt by the wake-up receiver. For each attempt, a detection result is generated that indicates whether the first signal was received with a signal quality that satisfies a predetermined minimum quality criterion. One or more of the detection results are used as a basis for deciding whether or not the wake-up receiver is within range of an access point. An operation of the mobile device is adjusted in response to a decision that the wake-up receiver is not within range of the access point.

A set of servers can support secure and efficient Machine to Machine communications using an application interface and a module controller. The set of servers can record data for a plurality of modules in a shared module database. The set of servers can (i) access the Internet to communicate with a module using a module identity, (i) receive server instructions, and (iii) send module instructions. Data can be encrypted and decrypted using a set of cryptographic algorithms and a set of cryptographic parameters. The set of servers can (i) receive a module public key with a module identity, (ii) authenticate the module public key, and (iii) receive a subsequent series of module public keys derived by the module with a module identity. The application interface can use a first server private key and the module controller can use a second server private key.
