    Abstract: A handover failure detection device (121) detects at least one of handover failure types regarding outgoing handover from a first cell (131) managed by a first base station (111) by observing: (a) presence/absence of reception by the first base station (111) of an acknowledgment response to a handover command regarding first handover of a mobile terminal (101) from the first cell (131) to a second cell (132) managed by a second base station (112); and (b) presence/absence of a request for connection re-establishment from the mobile terminal (101) to the first cell (131), the request occurring after initiation of the first handover. As a result, it contributes to improvement of handover failure detection or reduction of handover failure in a situation where exchange of information between base stations is restricted.

    Abstract: An object of the present disclosure is to provide a management apparatus, a communication apparatus, a system, a method, and a program capable of providing a service that meets a targeted KPI. A management apparatus according to the present disclosure includes: KPI management means for acquiring a target Key Performance Indicator (KPI) of a service that is provided to a communication terminal by a business operator; operation state acquisition means for acquiring element data regarding a component necessary for the service, the element data indicating a feature of a control system of the service; KPI prediction means for calculating a predicted KPI which is a predicted value of the KPI of the service based on the element data; and communication performance calculation means for, when the KPI is defined so that a value becomes lower as performance becomes better, detecting the component in which the predicted KPI is equal to or greater than the target KPI.

    Abstract: A traffic controller (8) receives, from a traffic monitor (7), a first control message generated in response to an increase in a total transmission rate of a plurality of packet flows sent from a plurality of wireless terminals (1) to a specific external network. The controller (8) determines, based on an evaluation criterion received from a criteria manager (6), one or more packet flows on which traffic shaping is to be imposed. In response to the first control message, the controller (8) controls a base station within a RAN (2) or a packet transfer node within a mobile backhaul (30) to execute the traffic shaping. This, for example, contribute to adjusting traffic that passes through a cellular communication network based on a monitoring result of a total transmission rate of traffic sent from the cellular communication network to the external network.

    Abstract: An external node (5) receives a transmission history (1301) regarding a first communication event of a first radio terminal (1) from a node (2) located in a radio access network (3). The external node (5) transmits to the node (2) a control request (1302) to control at least one of: a communication module (521) disposed in the node (2) for communicating with the external node (5); a scheduler (503, 903) disposed in the node (2); a data buffer (502, 11) disposed in the node (2) or the first radio terminal (1); and the first radio terminal (1). It is thus, for example, possible to contribute to an improvement for adapting packet scheduling to communication performed by an application of a radio terminal.

    Abstract: The base station notifies each mobile station of reporting conditions for causing the mobile station to transmit a measurement report containing measurement results of the radio quality. The reporting conditions include a first reporting condition and a second reporting condition in which the offset value added to the measurement result of the radio quality is greater than that of the first reporting condition and in which the guard time, that is a time from when the reporting condition is satisfied until the measurement report is transmitted, is shorter than that of the first reporting condition. The base station detects a mobile station that has transmitted a measurement report as a result of satisfaction of the second reporting condition as a handover required of mobile station whose radio quality becomes lower than a predetermined value within a predetermined period and performs a handover process of the mobile station.
