摘要： In femtocell operation, when a wireless communication terminal whose ID is not registered (ID unregistered terminal) has entered a femtocell's area, the disclosed invention prevents interference between the femtocell and the ID unregistered terminal and interference between the ID unregistered terminal and an ID registered radio communication terminal and prevents a decrease in the throughput of the femtocell and these terminals. In a radio coverage area formed by a radio base station, if a drop of received power from a radio communication terminal occurs and the frequency of reporting the ID of the base station now communicating with the terminal has become less than a given value, it is decided that the terminal is located indoors. For the terminal, if its handover to a femtocell was found to be rejected by MME, the terminal is temporarily permitted to be handed over to a femtocell.

摘要： A communication system includes a mobile terminal, a base station, a first gateway device, a second gateway device, a flow measurement server, a quality management server, and an operational terminal. A predetermined flow is extracted by a quality management server, and the extracted flow is summarized for each communication path. A distribution of the communication quality of the flow for each communication path is displayed on a display unit of the operational terminal.
