    摘要： A device management system according to one embodiment includes: a notification processing unit configured to obtain a proximity notification that represents a situation in which a portable connection source device is in proximity to a target connection destination device; and a connection determining unit configured to manage a connection between the connection source device and the target connection destination device through a radio communication network in response to the proximity notification. The connection determining unit is further configured to: refer to a database that stores a connection history representing past connections between the connection source device and one or more past connection destination devices; and connect the connection source device to the target connection destination device in response to a connection condition for connecting the connection source device to the target connection destination device being satisfied based on the connection history of the connection source device.

    摘要： When terminal identification information TI of one terminal device used by a user among two or more terminal devices is newly stored in a memory of a host device together with user identification information UI (S3a), an examination part examines, in the memory of the host device, a presence or absence of terminal identification information (terminal identification information TI-p) corresponding to the user identification information UI, excluding terminal identification information TI and terminal identification information corresponding to a terminal device that is currently used by the user (S11). When the terminal identification information TI-p exists, a management part performs control to transmit predetermined instruction information together with the terminal identification information TI-p to the two or more terminal devices (S12). When the terminal identification information TI-p received together with the instruction information from the host device matches own terminal identification information, an information erasure part erases information on a user other than the user who is currently stored in own memory (S13).

    摘要： Information indicating a base station apparatus with which each of a terminal apparatus T-k and other terminal apparatuses that are to perform location registration in a service area of a base station apparatus B(k) with which the terminal apparatus T-k is to perform location registration is shared among all the terminal apparatuses that are to perform location registration in the service area. A maximum wait time is set longer, the greater the number of other terminal apparatuses that are scheduled to perform location registration with the base station apparatus B(k) with respect to which the terminal apparatus T-k is to perform location registration is, the maximum wait time being a maximum wait time for the terminal apparatus T-K to access the base station apparatus B(k).

    摘要： A device management system according to one embodiment includes: an acquisition unit configured to obtain a proximity notification that represents a situation in which a portable connection source device is in proximity to one geographical range; and a list generating unit configured to transmit a candidate list representing candidate connection destination devices to the connection source device in response to the proximity notification. The list generating unit is further configured to: refer to a database storing a connection history that represents past connections between the connection source device and one or more past connection destination devices; select at least one of one or more devices corresponding to the geographical range as the candidate connection destination devices based on the connection history; and display the candidate list on the connection source device by transmitting the candidate list representing at least one candidate connection destination device to the connection source device.
