Abstract

A user equipment (UE) may determine, based on a criterion, whether to indicate, to a gNB, that it is a reduced capability (RedCap) UE during or after a random access (RA) procedure, and indicate that it is the RedCap UE during or after the RA procedure according to a determination result. The RedCap UE has a reduced quantity of receive branches or a reduce bandwidth than a non-RedCap UE. The gNB may determine whether a first message received during the RA procedure indicates that the UE is the RedCap UE. When the first message indicates the UE as the RedCap UE, the gNB sends a second message to the UE during the RA procedure using a coverage recovery technique. When the first message does not indicate the UE as the RedCap UE, the gNB determines whether the UE is the RedCap UE after the RA procedure is completed.

In this way, the terminal device can quickly access the cell, to reduce a delay of accessing the cell by the terminal device, and improve communication performance. The time domain resources occupied by the reference signal are fewer than the total time domain resources occupied by the SSB of the first cell and the SI of the first cell.

When playing a first advertisement, an advertising device broadcasts a wireless signal that includes an identifier of the first advertisement and bearing information used to indicate a position and an orientation of the advertising device. A first terminal receives the wireless signal, and when determining that the first advertisement played by the advertising device is effectively exposed to a user of the first terminal, sends an effective exposure event to a server. The effective exposure event includes a unified identity corresponding to the user of the first terminal and the identifier of the first advertisement, so that the server updates a historical preference of the user corresponding to the unified identity. The first terminal adds the unified identity when requesting an advertisement resource from the server, so that the server returns an advertisement resource of a second advertisement having a same advertising campaign as the first advertisement to the first terminal based on the unified identity.

That is, it is not necessary to wake up the terminal in advance, and as long as the received first speech input is semantically similar to the predefined first wake-up-free instruction, the terminal can execute an operation corresponding to the first speech input. Therefore, the problem of a terminal having no response due to the fact that a first wake-up-free instruction is fixed and limited is solved, and compared with an approach in which the terminal only responds to the predefined first wake-up-free instruction, the method greatly improves the interaction experience of a user.

Abstract

This disclosure relates to a device for a backup storage using a continuous data protection (CDP) system. The device receives a ransomware notification from the backup storage at a notification time point Tn. The ransomware notification indicates that one or more files of user data were encrypted by a ransomware. The device then enables the CDP system to generate a backup image of the user data at the time point Tn. The device further determines one or more time points Ti earlier than Tn, and enables the CDP system to generate backup images of the user data at the determined time points Ti. The device then determines, based on the backup images, a latest version of each file of the user data before the file was encrypted by the ransomware. The device further automatically restore each file in the backup storage to its corresponding latest version.

Abstract

Disclosed are a data processing system, a memory mirroring method and apparatus, and a computing device, relating to the field of computers. The system comprises a plurality of nodes and a management node. A first node requests to mirror a first area in a memory used by the first node; and the management node allocates a second area, the second area being used for indicating a storage space, in a second node, having the same size as the first area, and the second area being used for backing up data of the first area. When a node does not raise a memory mirroring demand, storage resources in the system are used for storing different data, and only when a memory mirroring demand is raised, a mirroring area is allocated from the storage resources of the system, so that the mirroring area backs up data stored in an area to be mirrored, thereby realizing high data reliability. In addition, the area to be mirrored and the mirroring area may be storage spaces in different nodes, so that the mirroring area can be flexibly and dynamically allocated to realize memory mirroring, thereby improving the flexibility of memory mirroring configuration and the utilization rate of storage resources.
