[Object] To make it possible to more stably perform communication. [Solution] There is provided a communication control device including: a communication status grasping unit configured to grasp a communication status of wireless communication of image information between an image shooting device and a surgical site image information acquiring unit on the basis of an operating room image showing a situation of an operating room, the image shooting device capturing an image of a surgical site of a patient, the surgical site image information acquiring unit acquiring information on a surgical site image captured by the image shooting device for display control of the surgical site image; and a communication method deciding unit configured to decide a communication method between the image shooting device and the surgical site image information acquiring unit on the basis of the grasped communication status.

An Integrated Access and Backhaul (IAB) node that communicates over a radio interface is provided. The IAB node includes: processing circuity configured to perform cell selection or cell reselection based on whether a corresponding cell is associated with an IAB donor or the IAB node. A hop number is defined for each of the IAB donor and the IAB node, where the hop number of the IAB donor is “0”.

Systems, devices, and techniques described herein relate to migrating a communication session from a path including a stressed user plane function (UPF) to a path including a replacement UPF. A communication session may traverse a first path including the first UPF. After establishing the communication session, the first UPF may be determined to be stressed. In response, the communication session can be proactively migrated to a second path including a second UPF. According to various implementations, the existing communication session can be maintained during the migration, thereby substantially eliminating interruptions caused by the stressed first UPF.

A computer system includes a virtual server to provide virtual computing sessions, and a client device to access one of the virtual computing sessions via a communications network. The client device includes a wireless transceiver connected to a cellular network. A server communicates with the client device via the cellular network based on the client device losing connectivity to the communications network. The cellular network provides a backup communications channel for the server to restore connectivity for the client device to access one of the virtual computing sessions via the communications network.
