Abstract: The present disclosure provides a user plane gateway updating method and apparatus, so as to resolve a prior-art technical problem that GW-U updating cannot be implemented when neither an MME nor a GW-C changes. Embodiments of the present disclosure provide four different solutions, for purposes of being compatible with an existing implementation mechanism and improving system efficiency, when a UE performs TAU, an EPS system of a distributed gateway can select, according to a current location of the UE, a best GW-U and re-establish a PDN connection, thereby optimizing a data transmission path and ensuring communication performance.

Abstract: Embodiments of the present invention provide an earphone volume adjustment method and apparatus. The method includes: when it is detected that an intensity of external environmental noise is greater than a preset threshold, obtaining position information and/or a motion status of a user; determining a time window according to the position information and/or the motion status; and adjusting earphone volume according to an intensity of external environmental noise in the time window. According to the embodiments of the present invention, an inappropriate phenomenon such as turning up or turning down the earphone volume in a short time can be avoided, and the earphone volume can be appropriately adjusted by comprehensively considering the intensity of the external environmental noise and the position information and/or the motion status of the user. Therefore, user experience is improved.

Abstract: A network slice management method, a management unit, and a system, where the method includes receiving, by a first management unit, a first management request, where the first management request carries requirement information of a network slice or indication information, and the indication information is used to obtain the requirement information of the network slice. The method further includes determining, by the first management unit, requirement information of a subnet that forms the network slice. According to the method, the first management unit can determine the corresponding requirement information of the subnet based on the requirement information of the network slice. This way, the network slice can be automatically deployed based on the requirement information of the network slice.

Abstract: A method and a device for performing communication by using a virtual subscriber identity module are used to provide a mode in which the device can perform communication without a SIM card. The method includes: receiving, by a first device, a virtual subscriber identity module data package sent by a second device by using a short range communications protocol, where the virtual subscriber identity module data package carries a virtual subscriber identity, and the virtual subscriber identity is used to uniquely identify a user using the first device when the first device performs communication in a network provided by a mobile communications operator; obtaining, by the first device, the virtual subscriber identity by using the virtual subscriber identity module data package; and communicating, by the first device by using the virtual subscriber identity, with another device in the network provided by the mobile communications operator.
