A method for controlling earphone switching and an earphone are provided. The method includes the following. A first earphone acquires a first remaining power and a first operating parameter of the first earphone and a second remaining power and a second operating parameter of a second earphone. The second earphone serves as a slave earphone. The first earphone predicts a first battery life of the first earphone according to the first remaining power and the first operating parameter and a second battery life of the second earphone according to the second remaining power and the second operating parameter. The first earphone predicts switches the second earphone to serve as a master earphone and the first earphone to serve as a slave earphone, when a difference between the second battery life and the first battery life is greater than a first preset threshold.

Extended sleep in a wireless device. In an embodiment, synchronized parameters, used by a wireless device to define an extended-sleep cycle, are stored at a system. Based on the synchronized parameters, the system determines a transmission time at which to transmit a message over the wireless communication network such that the message will be received by the wireless device during a portion of the extended-sleep cycle during which the wireless device is monitoring paging occasions. The message is then queued until it is transmitted at the transmission time.

Wireless communication equipment includes a communication interface, a memory, and a processor electrically connected with the communication interface and the memory. The processor is configured to activate communication of the wireless communication equipment, to scan an external device for a network connection at a periphery of the wireless communication equipment, using the communication interface, to receive information including a mesh ID sent from the external device, using the communication interface, and to configure a mesh network with the external device by using the communication interface, when a designated string stored in the memory is included in the mesh ID.

A module with an embedded universal integrated circuit card (eUICC) can include a received eUICC profile and a set of cryptographic algorithms. The received eUICC profile can include an initial shared secret key for authentication with a wireless network. The module can receive a key K network token and send a key K module token to the wireless network. The module can use the key K network token, a derived module private key, and a key derivation function to derive a secret shared network key K that supports communication with the wireless network. The wireless network can use the received key K module token, a network private key, and the key derivation function in order to derive the same secret shared network key K derived by the module. The module and the wireless network can subsequently use the mutually derived key K to communicate using traditional wireless network standards.

Disclosed is an improved implementation of a flood fill mesh network that utilizes probability forwarding for rebroadcasting network messages. The forwarding probability may be determined based on analyzing a network topology map constructed by each network node relative to its neighbor nodes communicating on the network and derived from state information contained in synchronization frames broadcasted by the network nodes on the network. The forwarding probability may comprise a statistical probability that a message frame received by a network node will be forwarded to the intended destination network node by one or more of the network node's neighbor network nodes.

A method for operating a node in a wireless network is provided that includes computing an estimated time drift between the node and a parent node of the node, and using the estimated time drift and a number of hops between the node and a root node of the wireless network to determine a keep alive period for the node.

Networked sleep mode management is provided by measuring network conditions for a first Access Point serving a plurality of client devices configured to operate in one of a sleep mode and an active mode; in response to detecting an amount of network usage devoted to transitioning members of the plurality of client devices from the sleep mode to the active mode satisfies a threshold: identifying a first subset of client devices from the plurality of client devices that are in the sleep mode; identifying a given client device from the first subset of client devices to transition to the active mode; and transmitting a tear-down message to the given client device that instructs the given client device to transition from the sleep mode to the active mode.

A method including determining whether an apparatus is to operate in a first, second or third mode of operation; wherein said first mode of operation includes a first level of activity, said second mode of operation includes a second level of activity that is lower than said first level of activity, and said third mode of operation includes a third level of activity that is lower than said second level of activity; applying a first reference signal transmission regime when in said second mode of operation; and applying a second reference signal transmission regime when in said third mode of operation.

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.
