Abstract: According to the present disclosure, a video analysis method and a video analysis system in which video analysis accuracy at a cloud server and an edge is improved is provided. The video analysis method includes a first image analysis step of analyzing an input image frame on the edge side, a difference value estimation step of estimating a difference value between an evaluation value of an analysis result in the first image analysis step and an evaluation value of an analysis result being predicted when the input image frame is analyzed by the cloud server, and a filtering step of determining whether to transmit the input image frame to the cloud server, based on the difference value.

Abstract: An object is to provide a management server for performing a technique to satisfy a predetermined latency requirement in an end-to-end flow. A management server (10) according to the present disclosure includes: a control unit (11) configured to distribute permissible latency associated with an end-to-end flow to an uplink flow and a downlink flow, where the end-to-end flow is to be transmitted from a communication terminal of a transmission source to a communication terminal of a transmission destination via an application server, based on a data size of the uplink flow, and a data size of the downlink data which is different from the data size of the uplink flow; and monitoring unit (12) configured to cause an uplink flow that has exceeded the permissible latency distributed to the uplink flow to be discarded in the communication terminal of the transmission source or the application server.

Abstract: There is provided a communication device capable of determining whether admission of new data traffic is allowed or rejected not by comparing throughputs only, but by considering other parameters when the data traffic is admitted. A communication device (10) according to the present invention includes a determination unit (11) that determines whether to admit a flow regarding a new radio terminal (30), the flow being to be transmitted between a radio terminal (30) and a base station (20) and having a transmission deadline, depending on a transmission state of a plurality of data packets included in the flow, and a communication unit (12) that transmits, to the base station (20), instruction information indicating whether to admit the flow regarding the new radio terminal (30).

Abstract: An exposure node (50) receives a first request for resource management for future background data transfer between an application service provider and a plurality of radio terminals (10) from a server (60) associated with the application service provider and send a second request to a policy control node (40) in response to receiving the first request. The first request includes a parameter indicating whether background data transfer not complying with a previously agreed or negotiated transfer policy should be stopped, or whether the background data transfer should continue under a charging rule different from a previously agreed charging rule. The second request includes the parameter obtained from the first request. This enables the application service provider to negotiate with the radio communication network about handling of background data transfer not complying with a previously agreed transfer policy.
