Abstract

A base station apparatus includes a wireless receiving unit wirelessly receiving identification information on a terminal apparatus located in the vicinity of the base station apparatus; a storage unit storing the identification information received by the wireless receiving unit; a request receiving unit receiving, from a communication apparatus, a start request containing identification information regarding a terminal apparatus to be started; a determination unit determining whether the identification information contained in the start request received by the request receiving unit having been stored in the storage unit; and a distribution unit wirelessly distributing a start instruction to start the terminal apparatus indicated by the identification information upon the determination unit determining the identification information having been stored in the storage unit.

Dependent claims

A base station apparatus comprising:

a receiver configured to wirelessly receive a media access control (MAC) address of a proximal terminal apparatus located in a vicinity of the base station apparatus, the MAC address being transmitted upon the proximal terminal apparatus being turned off;
a storage configured to store the received MAC address;
and
a processor configured to:
receive, from a communication apparatus, a start request containing one or more MAC addresses of one or more stopped terminal apparatuses to be started,
determine whether at least one of the one or more MAC addresses contained in the start request has been stored in the storage,
prepare a start instruction upon the processor determining that at least one of the one or more MAC addresses contained in the start request has been stored in the storage, the start instruction indicating a MAC address that has been stored in the storage and is contained in the start request, and
wirelessly distribute the start instruction to start the proximal terminal apparatus, wherein
when the wirelessly distributed start instruction was not received by the proximal terminal apparatus, the processor wirelessly redistributes the start instruction to the proximal terminal apparatus,
when the processor determines that the MAC address contained in the start request has already been stored in the storage, the storage registers the MAC address of the proximal terminal apparatus,
the receiver waits for a success message from the proximal terminal apparatus, in response to the start instruction,
the storage unregisters the MAC address of the proximal terminal apparatus after receipt of the success message, and
the processor wirelessly redistributes the start instruction when the success message is not received within a predetermined period of time.
