COMMUNICATION SYSTEM

摘要

A communication system capable of preventing unnecessary switching of an energy saving cell between a normal operation state and an energy saving state. An energy saving cell (ES cell) is in a dormant state that is the energy saving state. In this case, when being notified of a wake-up request message from a communication terminal device (UE), the ES cell executes access restriction control to judge whether the UE can access its own cell. If judging that the UE can access its own cell, the ES cell switches on its own cell and shifts from the dormant state to an active state that is the normal operation state.

主权项

1: A communication system comprising:
a communication terminal device; and a base station device that configures at least one cell capable of radio communication with said communication terminal device, wherein said at least one cell comprises an energy saving cell switchable between a normal operation state and an energy saving state in which power consumption is lower than in said normal operation state, and when said energy saving cell is in said energy saving state, access restriction control is executed to judge whether said communication terminal device is allowed to access said energy saving cell, and when it is judged that said communication terminal device is allowed to access said energy saving cell by said access restriction control, a wake-up process of shifting said energy saving cell from said energy saving state to said normal operation state is performed.
