Abstract

A communication system is provided that, if a large number of small cells are installed, is capable of configuring an operation suitable for small cells through simple operation and administration. If a small cell installed in Step ST 1401 judges in Step ST 1403 that a coverage macro cell, which includes the small cell in the coverage of the coverage macro cell, is present as a result of neighbor cell search in Step ST 1402 , notifies the coverage macro cell and another neighbor cell of its own capability in Steps ST 1404 and 1405 . The coverage macro cell selects a configuration parameter suitable for the capability of the small cell in Step ST 1406 and notifies the small cell in Step ST 1407 . The small cell recognizes an operation mode configured by the coverage macro cell from the configuration parameter notified from the coverage macro cell, and then, starts operating in the operation mode.

First claim

The invention claimed is:

1. A communication system comprising:
a communication terminal device including at least a controller and a wireless interface circuit to perform radio communication;
at least one base station device including a least a processor and a wireless interface circuit to configure a plurality of cells capable of radio communication with the communication terminal device; and
an entity including a processor coupled to at least one communication interface and configured to control the plurality of cells,
wherein each of the plurality of cells is configured to switch between a normal operation and an energy saving operation, the plurality of cells being grouped into a predetermined cell cluster according to an energy saving (ES) policy of each of the plurality of cells, and
the entity is configured to control switching between the normal operation and the energy saving operation of the plurality of cells.

2. The communication system according to claim 1 ,
wherein the entity is configured to control switching between the normal operation and the energy saving operation per cell cluster.

3. The communication system according to claim 1 ,
wherein the plurality of cells include a cell belonging a plurality of cell clusters.

4. A communication system comprising:
a communication terminal device including at least a controller and a wireless interface circuit to perform radio communication;
at least one base station device including a least a processor and a wireless interface circuit to configure a plurality of cells capable of radio communication with the communication terminal device; and
an entity including a processor coupled to at least one communication interface and configured to control the plurality of cells,
wherein each of the plurality of cells is configured to switch between a normal operation and an energy saving operation, the plurality of cells being grouped into a predetermined cell cluster according to an energy saving (ES) policy of each of the plurality of cells,
the entity is configured to control a cell being a moving destination of the communication terminal device to shift to the normal operation before the communication terminal device moves into the cell, and
the entity is configured to control switching between the normal operation and the energy saving operation per cell cluster.
