Abstract: A task scheduling method and system, and a hardware task scheduler are disclosed, and pertain to the field of computer technologies. The hardware task scheduler provides task scheduling for a central processing unit CPU core to select a candidate task. After selecting the candidate task, the CPU core actively sends metadata of the candidate task to a first storage area, and actively sends a context of the candidate task to a cache, where the first storage area is located in storage space whose access speed is higher than that of a memory. When performing task switching, the CPU core reads the metadata of the candidate task from the first storage area, and reads the context of the candidate task from the cache. In this way, latency of obtaining the metadata and the context of the candidate task by the CPU core is reduced, and low-latency task switching is implemented.

Abstract: Example cell access methods and apparatus are described. In one example method, a terminal device receives a first message in a cell of a first carrier. The first message includes remaining minimum system information (RMSI) of a cell of a second carrier and a first indication, and the first indication indicates information about a first bandwidth part (BWP). The terminal device accesses the cell of the second carrier based on the first BWP and the RMSI.

Abstract: A handover method and a communication apparatus are provided. The method includes: After sending a handover command to a terminal device, a source network device sends, to a target network device, at least one data packet that is not successfully received by the terminal device, so that after the terminal device accesses the target network device, the target network device sends, to the terminal device, the at least one data packet received from the source network device. Because the data packet forwarded by the source network device to the target network device includes a data packet on which the source network device has performed PDCP processing and for which no acknowledgment response from the terminal device is preceived, a data loss of the terminal device in an inter-system handover process can be effectively avoided.
