  • Patent number: 11126661
    Abstract: Provided is a technique of preventing incorrect execution of a search function that is not intended by a user. A voice recognition apparatus includes an acquisition unit, an estimation unit, an execution frequency storage, and a controller. The acquisition unit acquires a voice. The estimation unit estimates a search function to be executed, by recognizing the voice acquired by the acquisition unit. The execution frequency storage stores the execution frequency of the search function. The controller refers to the execution frequency of an estimation search function, and then controls the execution of the estimation search function. The estimation search function is the search function estimated by the estimation unit.

  • Publication number: 20210289440
    Abstract: 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.
