Abstract
In a communication system 10, a management device 100, which is under the control of the MVNO, collects radio quality information from a UE 500 by using a communication channel established between the management device 100 and the UE 500, selects an optimum cell by using the collected radio quality information, and notifies the UE 500 of the selected optimum cell. The UE 500 then connects or hands over to the optimum cell notified by the management device 100.
Claims5
A communication method performed by a communication system that includes a management device and a mobile device that can perform communication with the management device via a predetermined communication channel, the communication method comprising:
- collecting, performed by the mobile device, radio quality information that indicates radio qualities of a cell that is currently being used for communication by the mobile device and of adjacent or overlapping cells of the cell;
- first transmitting, performed by the mobile device, the collected radio quality information to the management device by using the communication channel;
- receiving, performed by the management device, the radio quality information from the mobile device by using the communication channel;
- selecting, performed by the management device, an optimum cell with a desired radio quality from the adjacent or overlapping cells by using the received radio quality information;
- second transmitting, performed by the management device, optimum cell information that indicates the selected optimum cell to the mobile device by using the communication channel;
- and
- connecting or handing over, performed by the mobile device, to the optimum cell indicated by the transmitted optimum cell information.
A management device that can perform communication with a mobile device via a predetermined communication channel, the management device comprising:
- a radio-quality information receiving unit that receives, from the mobile device by using the communication channel, radio quality information that indicates radio qualities of a cell that is currently being used for communication by the mobile device and of adjacent or overlapping cells of the cell;
- an optimum-cell selecting unit that selects an optimum cell with a desired radio quality from the adjacent or overlapping cells by using the radio quality information received by the radio-quality information receiving unit;
- and
- an optimum-cell information transmitting unit that transmits optimum cell information that indicates the optimum cell selected by the optimum-cell selecting unit to the mobile device by using the communication channel.
A mobile device that can perform communication with a management device via a predetermined communication channel, the mobile device comprising:
- a radio-quality information collecting unit that collects radio quality information that indicates radio qualities of a cell that is currently being used for communication by the mobile device and of adjacent or overlapping cells of the cell;
- a radio-quality information transmitting unit that transmits the radio quality information collected by the radio-quality information collecting unit to the management device by using the communication channel;
- an optimum-cell information receiving unit that receives, from the management device by using the communication channel, optimum cell information that indicates an optimum cell with a desired radio quality, the optimum cell being selected from the adjacent or overlapping cells by the management device by using the radio quality information transmitted by the radio-quality information transmitting unit;
- and
- an optimum-cell connecting unit that connects or hands over to the optimum cell indicated by the optimum cell information received by the optimum-cell information receiving unit.
