Abstract: Embodiments of the present invention provide a method for paging between NAN devices, and a NAN device, and relate to the field of communications technologies, so that paging can be directly performed between NAN devices when there is no central node. The method includes: sending, by a first NAN device, a first paging message in a first window; receiving a paging response message sent by a second NAN device that meets first service information; and determining, according to the paging response message, whether to perform data transmission with the second NAN device. The first paging message carries the first service information, and the first service information is used to describe a service that needs to be performed by the NAN device. The method is applied to a NAN mechanism.

Abstract: The present invention discloses a service processing method and apparatus, which belong to the field of Internet technologies. After the AP and an STA first perform MAC address change notification and then establish a first MAC connection, the AP sends service data of the STA to the STA through the first MAC connection by using a resource related to a second MAC connection. Therefore, in a MAC address change process, there is no need to re-establish a resource at an upper layer of a MAC layer, and only a change in invoking a MAC layer resource is required at a layer at which the MAC layer resource is used. Time and a resource for processing a service can be reduced without affecting service continuity and stability of the upper layer. Therefore, the service is processed in a timely manner and service processing efficiency is improved.

Abstract: A memory access method is applied to a computer system including a hybrid memory. The hybrid memory includes a first memory and a second memory. According to the method, after receiving a first access request including a first virtual address, the first virtual address is translated into a first physical address, where the first physical address is a physical address of a first large page in the first memory, and the first large page includes a plurality of small pages. When it is determined that data of a first small page in the first large page is migrated to the second memory, accessing the second memory according to a second physical address stored in the first small page, where the second physical address is a physical address of a second small page in the second memory, the second small page stores the data migrated from the first small page.
