Connection change restriction in overlapping area of terrestrial network and non-terrestrial network

An information processing apparatus executes an acquiring process, a prediction process, and a determination process. The acquiring process is a process for acquiring, from a communication apparatus, a communication status for the communication apparatus before handover. The prediction process is a process for predicting, based on the communication status before handover, a communication status for the communication apparatus after handover using machine learning. The determination process is a process for determining, based on the predicted communication status after handover, an Service and Session Continuity (SSC) mode to be used by the communication apparatus after handover.

Communication control for dynamically determining SSC mode

A management apparatus executes a determination process and an offloading control process. The determination process is a process for determining whether a processing load in an execution server, among a plurality of edge servers, executing a processing requested by a plurality of communication apparatus meets a distribution start condition. The offloading control process is a process for, in a case where it is determined that the processing load meets the distribution start condition, controlling to offload a processing being executed by the execution server to one or more offload destination servers, among the plurality of edge servers, that is different from the execution server to meet a processing request time for the requested processing.

Network management for offloading

A communication control apparatus has: a communication device detection unit that detects a communication device in a non-terrestrial communication cell provided on the ground by a flying non-terrestrial base station; a terrestrial communication cell detection unit that detects a terrestrial communication cell that can be provided on the ground by a terrestrial base station installed on the ground; and a terrestrial base station operating state control unit that controls the operating state of the terrestrial base station based on the detection results of the communication device detection unit and the terrestrial communication cell detection unit. The terrestrial communication cell detection unit and the terrestrial base station operating state control unit are installed in a ground station that is installed on the ground and can communicate with the non-terrestrial base station.

Control of operating state of terrestrial base station via non-terrestrial base station

A communication control apparatus comprising: a first paging control unit that causes one base station of a terrestrial base station and a non-terrestrial base station to transmit a first paging signal to a communication device in a location registration area that includes at least one terrestrial communication cell provided on the ground by the terrestrial base station installed on the ground and at least one non-terrestrial communication cell provided on the ground by the flying non-terrestrial base station; and a second paging control unit that causes other base station of the terrestrial base station and the non-terrestrial base station to transmit a second paging signal to the communication device, when there is no response from the communication device to the first paging signal.

Paging control for terrestrial and non-terrestrial networks

A wireless communication system includes: a priority communication detection unit that detects priority communication from a communicator communicating wirelessly; a connection unit for connecting the communicator for which the priority communication is detected to a second wireless communication network that is different from a first wireless communication network to which the communicator is connected; a notification unit that notifies the first wireless communication network that the connection of the communicator to the second wireless communication network is due to the detected priority communication; and a disconnection unit that disconnects the communicator from the first wireless communication network after the notification unit notifies the first wireless communication network.

Connection and notification for priority communication

A communication system executes a sharing process, an acquisition process, a determination process, a deployment process, and an execution process. The sharing process is a process of sharing a shared key for a plurality of entities including a communication apparatus and at least one edge server, between the plurality of entities. The acquisition process is a process of acquiring performance information, which indicates a performance of the plurality of entities, from the plurality of entities. The determination process is a process of determining services to be assigned to the plurality of entities based on the performance information. The deployment process is a process of deploying the assigned services to the plurality of entities.

Network management for executing a service using a plurality of entities

A communication device provided with a chip set and one or more processors. The one or more processors acquire, from a preferred application with which a provided service is to be received via a communication network, a requirement for receiving the provided service, refer to a policy file to select a slice satisfying the requirement from among slices provided in the communication network, generate a first communication connection request associated with an application corresponding to the selected slice, the first communication request being independent from the preferred application with which the provided service is to be received via the communication network, and notify the chip set of the first communication connection request. Upon acquiring the first communication connection request, the chip set sends, to the communication network, a second communication connection request for performing communication associated with the application with which the provided service is to be received.
