Method and apparatus for monitoring the status and location of personnel using a remote timer. In some embodiments, a method includes execution of a subject application (app) on a network accessible device. A countdown timer of a remote server is initiated to monitor a time interval, the remote server communicating with the network accessible device over a network. Geo positions of the network accessible device are monitored during the monitored time interval. The remote server sends a notification to a monitoring device responsive to at least one of the following events: the monitored time interval ends without the remote server receiving an authorized personal identification (PID) value; or the remote server receives an unauthorized PID value prior to the conclusion of the monitored time interval. In further embodiments, a notification is sent based on an out-of-bounds geo position of the network accessible device during the time interval.

A protocol data unit (PDU) type setting method, a user equipment (UE) policy setting method, and a related entity, where the PDU type setting method includes: setting, by UE, a requested PDU type of a PDU session in a process of establishing the PDU session, where the requested PDU type of the PDU session is set by the UE based on a first condition, the first condition includes an Internet Protocol (IP) version corresponding to an application, and the application is associated with the PDU session. In the embodiments of the present disclosure, the requested PDU type of the PDU session can be consistent with a PDU type requested by the application, such that the application can normally perform communication.

A sensor platform includes a programmable microcontroller to execute programming associated with one or more sensors in order to receive data from the one or more sensors and generate reports based on the data, and to enter a power-down mode in the absence of the data. The sensor platform also includes first and second transceivers. The first transceiver is configured to establish wireless connectivity with user devices using a first wireless protocol and to receive the programming from one or more of the user devices using the first wireless protocol. The second transceiver is configured to transmit the reports to a gateway using a second wireless protocol that is lower power, longer range, and/or lower fidelity than the first wireless protocol.

A wireless communication terminal for wireless communication is disclosed. The wireless communication terminal includes: a transceiver; and a processor. The processor is configured to transmit a non-legacy physical layer frame including a legacy signaling field including information decodable by a legacy wireless communication terminal by using the transceiver.

The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node.
