Disclosed is an electronic apparatus, the electronic apparatus including: a communication circuitry; a power supply; a first processor configured to have a first mode which receives first power from the power supply and connects with a server through the communication circuitry to transmit and receive information, and a second mode which receives no power or second power lower than the first power from the power supply; and a second processor configured to repetitively output a mode switching signal within a preset range of time interval based on the second mode of the first processor, wherein the first processor is switched over to the first mode based on the mode switching signal, is configured to transmit connectivity keeping information to the server through the communication circuitry and is switched over to the second mode.

A method, operational at a device, includes receiving at least one packet belonging to a first set of packets of a packet flow marked with an identification value, determining that the at least one packet is marked with the identification value, determining to change a quality of service (QoS) treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received, and sending a request to change the QoS treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received to trigger a different QoS treatment of packets within the packet flow, responsive to determining to change the QoS treatment. Other aspects, embodiments, and features are also claimed and described.

A technique for message history display includes combining message histories for multiple different messaging services. A system constructed according to the technique may include, for example, a message history database; a history aggregation engine that aggregates message logs for storage in the message history database; and a history provisioning engine that provides an aggregated message log associated with the user from the message history database to a requesting device. A method according to the technique may include, for example, identifying a device in association with a user profile; providing an online platform that receives messages from and sends messages to the device; and creating an aggregated log from messages sent to and from the device.

A security policy deployment method and apparatus are provided, and the method includes: when a lifecycle state of a virtualized network function VNF changes, generating, by a management network element, a security policy of the VNF, where the security policy of the VNF is used to perform access control on the VNF; and sending, by the management network element, the security policy of the VNF to a control device. The management network element is a network element configured to perform lifecycle management on the VNF. By using the method or apparatus provided in embodiments of this application, the security policy of the VNF can be adjusted in time when the lifecycle state of the VNF changes, thereby greatly reducing a possibility that a bug occurs in the security policy of the VNF because the VNF changes.
