Abstract
(EN) The purpose of the present invention is to provide a server device which, if a frequency channel being used by an access point is no longer identifiable, makes it possible to identify an access point to be monitored. A first aspect of the present disclosure relates to a server device (10) comprising: a managing unit (11) for managing a list indicating a first access point among a plurality of access points to be monitored that has become unable to be monitored; a communication unit (12) for transmitting to a sensor device a collection condition indicating a frequency channel available to the first access point, and receiving monitor data generated from packets collected by the sensor device in accordance with the collection condition; and a monitoring unit (13) which resumes monitoring of the first access point if information identifying the first access point is included in the monitor data.
(FR) La présente invention a pour but de fournir un dispositif serveur qui, si un canal de fréquence utilisé par un point d'accès n'est plus identifiable, permet d'identifier un point d'accès à surveiller. Selon un premier aspect de la présente invention, un dispositif serveur (10) comprend : une unité de gestion (11) pour gérer une liste indiquant un premier point d'accès parmi une pluralité de points d'accès à surveiller dont la surveillance n'est plus possible ; une unité de communication (12) pour transmettre, à un dispositif capteur, une condition de collecte indiquant un canal de fréquence disponible pour le premier point d'accès, et pour recevoir des données de surveillance générées à partir de paquets collectés par le dispositif capteur conformément à la condition de collecte ; et une unité de surveillance (13) qui reprend la surveillance du premier point d'accès si des informations identifiant le premier point d'accès sont incluses dans les données de surveillance.
(JA) アクセスポイントが使用する周波数チャネルを特定することができなくなった場合に、監視対象のアクセスポイントを特定することができるサーバ装置を提供することを目的とする。本開示の第1の態様にかかるサーバ装置(10)は、監視対象の複数のアクセスポイントのうち、監視することができなくなった第1のアクセスポイントが示されるリストを管理する管理部(11)と、第1のアクセスポイントが使用可能な周波数チャネルを示す収集条件をセンサ装置へ送信し、センサ装置において収集条件に従って収集されたパケットから生成された監視データを受信する通信部(12)と、監視データに第1のアクセスポイントを特定する情報が含まれる場合、第1のアクセスポイントの監視を再開する監視部(13)と、を備える。
