Abstract: Embodiments of this application provide a terminal configuration method and an apparatus. When determining that a SIM card in a terminal is powered on, a wireless communications module reads SIM card information such as some or all of an international mobile subscriber identity (IMSI), a service provider name (SPN), or a global identifier ID (GID) in the SIM card from the SIM card. After that, the SIM card information obtained by the wireless communications module is sent to an application processor. The application processor obtains an operator parameter based on the SIM card information reported by the wireless communications module, and configures the terminal. Therefore, at a moment at which the SIM card is powered on, the wireless communications module obtains the SIM card information from the SIM card, so that a timing for the UE to obtain the IMSI is advanced.

Abstract: The present application discloses a virtual trusted platform module (vTPM)-based virtual machine security protection method and system. The method, executed by a physical host, includes: receiving a primary seed acquisition request sent by a virtual machine, where the primary seed acquisition request carries a UUID; sending the UUID to a KMC, so that the KMC generates a primary seed according to the UUID; and receiving the primary seed fed back by the KMC, and sending the primary seed to the virtual machine, so that the virtual machine creates a root key of a vTPM according to the primary seed, where the root key is used by the vTPM to create a key for the virtual machine to protect security of the virtual machine. As such, the same root key can be created by using the primary seed.

Abstract: This application relates to wireless communications technologies, and in particular, to a random access device, method, and system. In a network device provided in this application, a processing module is configured to determine a same processing result for random access procedures initiated by N terminal devices in M terminal device sets, where M and N are positive integers; and a sending module is configured to send a same random access control message to the N terminal devices, where the random access control message indicates the same processing result determined by the processing module, the message includes terminal set identification information, and the terminal set identification information identifies the N terminal devices. The network device uses a same random access reject message to indicate the same processing result for the random access procedures to the N terminal devices.

Abstract: A method and an apparatus for monitoring a wavelength channel are disclosed. The method includes: performing optical-to-electrical detection on an optical signal on a wavelength channel, to obtain an electrical signal; obtaining a frequency spectrum of the electrical signal; determining a first parameter M according to an equation M=NAC, where NAC represents an alternating current component of the frequency spectrum of the electrical signal; and if M is greater than a preset first threshold, determining that the wavelength channel includes a real service signal. According to the method and apparatus, an erroneous configuration or operation of a network management system can be avoided.
