Abstract: A call processing method and call processing device are provided. The method provides a media server that receives an initial call request sent by a calling terminal and forwards the initial call request to a called terminal. The media server receives a success response to the initial call request from the called terminal, and performs video resource negotiation with the called terminal.
The media server sends, based on video resource negotiation with the called terminal, a video stream to the called terminal. In an audio call process between a calling user and a called user, a video stream can be sent to the called user. This improves user experience and improves network capability utilization.-

Abstract: An image processing method includes segmenting, by a cloud server and based on a zoom ratio of a high-definition image in a high-definition image library, a low-definition image of a small zoom ratio from a terminal to obtain a plurality of image blocks. For each image block, performing, by the cloud server, retrieval and matching in the high-definition image library to obtain one or more high-definition reference images, and then performing, by the cloud server, image quality improvement using an image enhancement network that is based on the high-definition reference images to obtain a plurality of high-definition image blocks. Finally, stitching, by the cloud server, the high-definition image blocks into a super-definition image with higher resolution and higher definition, and returning, by the cloud server, the super-definition image to the terminal.

Abstract: A central node of the system is connected to a working node through a network device. The central node generates a plurality of tasks based on a query request input by a user. When allocating execution devices to the plurality of tasks, the central node configures execution devices of some tasks as the network device, configures execution devices of some tasks as the working node, and then sends configuration instructions to the configured network device and working node, to set, on the network device and the working node, tasks configured for the network device and working node. After configuration is completed, the network device executes the set tasks on the data that passes through the network device.
