The embodiments of the present disclosure are applicable to the technical field of computer science and application technology, and disclose a wireless body area network, a key generation method and a key distribution method in the wireless body area network, and a related device. The gait acceleration signal is extracted synchronously through the respective acceleration acquisition devices integrated with the coordinator and the wearable equipment, the position information corresponding to the peak value and the valley value in the gait acceleration signal is correspondingly extracted and is taken as the gait common information, and the gait common information is used to perform key distribution in the wireless body area network, the security and the consistency are higher, the calculation is simplified, the key distribution method is suitable for wearable devices having limited resources.

A method, performed by a user equipment (UE), of managing secondary platform bundles (SPBs), includes receiving an end user selection for managing a state of at least one SPB among SPBs installed in a smart secure platform (SSP) module; checking bundle management information required to manage the state of the at least one SPB based on the end user selection; determining whether end user intent confirmation is required to manage the state of the at least one SPB according to the end user selection based on the bundle management information; and managing the state of the at least one SPB based on a result of the determining.

In some embodiments, a supervising electronic device manages communication restrictions of a supervised electronic device. In some embodiments, a supervised electronic device presents user interfaces that enforce one or more communication restrictions configured by a supervising electronic device when communicating with other users.

An audio bridge unit is provided for connecting a conventional analog page/party station in an analog page/party system to IP-based page/party stations that employ multicast Voice over Internet Protocol (VoIP) technology to support page/party communications between analog page/party stations and the VoIP page/party stations. The audio bridge unit converts page and/or party audio line(s) to multicast channel(s). The audio bridge unit analog interfaces for its respective page and/or party lines, and each analog interface is assigned to an independent multicast channel on which it will transmit and receive full duplex audio between an analog page/party station and one or more IP-based page/party stations. The audio bridge unit provides the ability to configure the multicast group, port and Time to Live (TTL) setting for each of the analog channels associated with the page and/or party lines.

Embodiments of the present invention provide methods and devices for transmitting or receiving beacon frames and probe response frames that include MAC addresses of a multi-link device (MLD) operating on multiple links in a wireless network. For example, the beacon frames and probe response frames can include an MLD MAC address that uniquely identifies an AP MLD in a wireless network, and can optionally include one or more WM MAC addresses of STAs of the AP MLD. The MAC addresses can be used to by wireless devices (e.g., STA MLDs) to connect to and associate with the AP MLD, and can be used to generate a password element used during authentication between wireless devices.

A mobile communication device that adapts its usage of antennas based on a rule set and an operation context. The device comprises a plurality of antennas, a radio modem, a processor, a non-transitory memory, and a client application stored in the non-transitory memory. When executed by the processor, the application receives a biometric input for authenticating a session of a user on the device, wherein the biometric input is associated with a biometric profile, sends a request for a rule set to a server computer, and receives the rule set. The application further stores the rule set, evaluates the rule set based on the operation context to determine an antenna operation setting, and commands the radio modem to configure itself to the antenna operation setting, whereby the radio modem is restricted from using all of the plurality of antennas at the same time in at least some operation contexts.

A system of security for a remote user authentication service (RUAS) comprising: an authentication server, mobile wireless device with a SIM card embedded in the mobile wireless device and a RUAS logic that provide a multi-factor remote user authentication service, where one of the factors is a “what you have” factor of authentication, an electronic token in physical possession of the user that is interfaced with the authentication server over the global computer network; the SIM card, embedded in the mobile wireless device, emulates the electronic token to provide the “what you have” factor, thus obviating the need for the business to provision and for the user to carry a separate physical electronic token.

A mobile application capable of superseding default phone settings to give priority to calls and messages based on a preconfigured list, as well as broadcast messages and calls within a defined group of members.

Embodiments of the present invention provides an information obtaining method and a device. The method is applied to a base station, and includes: sending first information to a mobile management entity (MME), where the first information includes a first request used to re-establish an radio resource control (RRC) connection, the first request is used to instruct the MME to send second information to the base station, the second information includes context information of user equipment (UE) and indication information that is used to indicate connection establishment, and the UE is a UE that requests the RRC connection re-establishment; and receiving the second information. In the embodiments of the present invention, steps in a process of RRC link re-establishment can be reduced, thereby shortening time for re-establishing an RRC connection.
