Abstract: An RRC connection release control method and an apparatus are applied to the field of mobile communication technologies and relate to the field of artificial intelligence (AI) and machine learning algorithms. When a first application of a terminal runs in a foreground, a timing duration of a first timer is set based on a timing duration corresponding to the first application, where the first timer starts when the terminal is in an RRC connected state, and when the terminal exchanges information with a network device, the first timer is reset, so as to control release of an RRC connection of the terminal based on the first timer.

Abstract: In a storage medium management method, a controller receives an address space request that requests the provision of an address space in a target storage medium for an operating system, the target storage medium having two different types of storage media. The Controller determines a first address space in the target storage medium based on the address space request, and a physical address of the first address space to a target virtual address, which is managed by the operating system. The controller then provides to an operating system a first address space requested by the address space request, such that the first address space is directly managed by an operating system, without manual configuration or restart of an electronic device.

Abstract: An equalization current adjustment method includes: determining a battery unit to be equalized in a battery pack, and obtaining a current actual equalization current value of the battery unit; and when it is determined that a difference between the current actual equalization current value of the battery unit and a target equalization current value does not fall within a range of a preset threshold, adjusting a fundamental amplitude of an alternating current power supply of a target circuit on which the battery unit is located and/or a voltage gain of the target circuit, so that the difference between the current actual equalization current value of the battery unit and the target equalization current value falls within the range of the preset threshold.

Abstract: Embodiments of this application disclose a baseband unit (BBU) and an access network device. The BBU includes M lasers, M switches (SWs), M photodetectors (PDs), an arrayed waveguide grating (AWG), M transmit ports, and M receive ports, where M is an integer greater than or equal to 2. An ith laser is coupled to an input end of an ith SW, an upper output end of the ith SW is coupled to an ith transmit port, and the AWG is separately coupled to lower output ends of the M switches SWs, the M PDs, and the M receive ports, where i=1, 2, . . . , or M. When a networking mode used by the BBU needs to be changed, an optical module or a component in the BBU does not need to be replaced, so that applicability, universality, and flexibility of the BBU can be improved.

Abstract: A computer system includes a first computing node and a second computing node. The first computing node includes a first device and a first memory. The second computing node includes a second device and a second memory. The first memory includes a first memory space. The second memory includes a second memory space. The first device obtains a cross-node read instruction. The cross-node read instruction includes a virtual address of the second memory space and a size of first data. The first device determines an identifier (ID) of the second computing node based on the virtual address of the second memory space and a first correspondence, to obtain a first network transmission packet, and sends the packet to the second device. The second device receives the packet, reads the first data from the second memory space, and sends the first data to the first device.

Abstract: A frequency regulation method and apparatus is applied to an insulation impedance detection apparatus in a direct current power system, and relates to the field of security monitoring technologies of a direct current electrical system. The method includes: collecting sampling voltages at a sampling point for at least three time points; determining a voltage frequency regulation manner based on the sampling voltages, obtained through sampling, at the at least three time points; and then regulating a voltage frequency of a power supply according to the determined voltage frequency regulation manner. The voltage frequency of the power supply can be regulated based on the at least three sampling voltages obtained through sampling. Therefore, the insulation impedance detection apparatus reduces insulation impedance detection duration while ensuring accuracy of measured insulation impedance.

Abstract: An electronic device includes a first transmission circuit and an anti-interference circuit. The first transmission circuit includes a first receive end, a first transmit end, and a first conversion module. The first conversion module is configured to convert a first-type signal in a signal received by the first receive end into a second-type signal to be sent by the first transmit end. The anti-interference circuit is configured to cancel the second-type signal in the signal received by the first receive end. The cancelled second-type signal is sent by the first transmit end and then received by the first receive end.
