Abstract
A communication system includes a base station configuring an energy saving cell (ES cell) and a base station configuring a compensation cell (Comp cell). The ES cell is switchable between a switch-on state and a switch-off state. The Comp cell compensates for the coverage of the ES cell when the ES cell is in the switch-off state. Before the Comp cell starts compensating for the coverage, for example, before the ES cell decides to switch itself off in Step ST2101, in Step ST2201 for example, the base station configuring the ES cell notifies the UE being connected with the ES cell of the information about a Comp cell, for example, a Comp cell list.
Claims3
A communication system, comprising:
- base station devices and a communication terminal device configured for radio communication with the base station devices, wherein
- the base station devices include:
- an energy saving base station device configuring an energy saving cell configured to switch between a normal operation state and an energy saving state with power consumption lower than that of the normal operation state, and
- a compensating base station device configuring, when the energy saving cell is in the energy saving state, a compensation cell that compensates for a coverage being a range in which the energy saving cell is capable of communication;
- and
- when switching from the normal operation state to the energy saving state is decided, the energy saving cell broadcasts, to the communication terminal device in a coverage of its own cell, broadcast information indicating that its own cell is not selectable as a cell targeted for communication.
