Publication number: 20150111554Abstract: In operation control for a femto base station apparatus, file updating is performed only for an apparatus needing updating only when needed to prevent the bandwidth of the network from being narrowed. Version information of a file necessary for the operation control for a femto base station apparatus is obtained before performing the operation control. Then, it is confirmed whether or not the obtained version information matches the version information of the file stored in the storage unit. The operation control is performed when matching is confirmed. Contrarily, a version of the file necessary for the operation control is obtained and the file updating is performed when a version confirming unit confirms mismatching of the version information.Type: ApplicationFiled: February 8, 2013Publication date: April 23, 2015Applicant: NTT DOCOMO, INCInventors: Hiroto Tooyama, Kentaro Fujii, Yuuki Kishikawa, Satoshi Namie, Kazuhide Takahashi
