Abstract: A memory management method, apparatus, and system are provided. The memory management method is performed by a memory management hardware accelerator, and the memory management hardware accelerator is coupled to an application subsystem and a communications subsystem. The application subsystem is configured to run a main operating system, and the communications subsystem is configured to run a communications operating system. The method includes: obtaining a set of memory addresses corresponding to dynamic memory space allocated by the main operating system to the communications subsystem, where the set of memory addresses includes one or more memory addresses; and sending some memory addresses in the set of memory addresses to a component of the communications subsystem.

Abstract: Embodiments of the present application disclose a dual-card dual-active communication method. A terminal includes a radio frequency circuit, a first modem and a second modem. The first modem includes a first IMS module, and the second modem includes a second IMS module. The method includes: sending, by the first IMS module, a first access request to a first gateway on a network side via the first modem and the radio frequency circuit, to request to access a first IMS network on the network side; and when the first IMS module stably camps on the first IMS network via the first gateway, sending, by the second IMS module, a second access request to a second gateway on the network side via the first modem and the radio frequency circuit, to request to access a second IMS network on the network side.
