COMMUNICATION SYSTEM, COMMUNICATION TERMINAL DEVICE AND BASE STATION DEVICE Russian patent published in 2019 - IPC H04W8/00 H04W52/02 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication. Communication system is provided to prevent an unnecessary transition of an energy-saving cell between a normal operation state and an energy-saving state. At step ST1101, the energy-saving cell (ES cell) is in an inactive state, which is a power-saving state. In this case, having received the awakening request message from the communication terminal unit (UE) in step ST1104, the ES cell performs, in step ST1106, access restriction management for deciding whether the UE can access its own cell. If it is decided that the UE may access its own cell, the ES cell includes its own cell at step ST1109 and at step ST1110 changes from an inactive state to an active state which is a normal operation state.

EFFECT: preventing the unnecessary transition of an energy-saving cell between the state of normal operation and the state of energy saving.
