A system for preventing a user input device from controlling user equipment (102, 700), the system comprising: means (104, 704) for receiving, over a first communications path or a second communications path, by the user equipment (102, 700), data indicative of a first request to restrict control by the user input device over the user equipment, said means (104, 704) for receiving comprising receiver circuitry for receiving over the second communications path, the first communications path being different from the second communications path; means for, based on receiving the data indicative of the first request, disregarding, by the user equipment (102, 700), a first command transmitted from the user input device over the second communications path, the first command intended to alter a setting of the user equipment; means for, subsequent to receiving the data indicative of the first request, receiving, over the first communications path, by the user equipment (102, 700), data indicative of a second request to restore control by the user input device over the user equipment (102, 700); means for receiving, over the second communications path and subsequent to receiving the data indicative of the second request, a second command from the user input device, the second command intended to alter a second setting of the user equipment (102, 700); and means for altering, based on the second command, the second setting of the user equipment (102, 700); wherein: the means for disregarding, by the user equipment (102, 700), the first command from the user input device is configured to: disable the receiver circuitry for receiving over the second communications path in response to receiving the data indicative of the first request; reenable the receiver circuitry for receiving over the second communications path in response to receiving the data indicative of the second request. means (104, 704) for receiving, over a first communications path or a second communications path, by the user equipment (102, 700), data indicative of a first request to restrict control by the user input device over the user equipment, said means (104, 704) for receiving comprising receiver circuitry for receiving over the second communications path, the first communications path being different from the second communications path; means for, based on receiving the data indicative of the first request, disregarding, by the user equipment (102, 700), a first command transmitted from the user input device over the second communications path, the first command intended to alter a setting of the user equipment; means for, subsequent to receiving the data indicative of the first request, receiving, over the first communications path, by the user equipment (102, 700), data indicative of a second request to restore control by the user input device over the user equipment (102, 700); means for receiving, over the second communications path and subsequent to receiving the data indicative of the second request, a second command from the user input device, the second command intended to alter a second setting of the user equipment (102, 700); and means for altering, based on the second command, the second setting of the user equipment (102, 700); wherein: the means for disregarding, by the user equipment (102, 700), the first command from the user input device is configured to: disable the receiver circuitry for receiving over the second communications path in response to receiving the data indicative of the first request; reenable the receiver circuitry for receiving over the second communications path in response to receiving the data indicative of the second request. disable the receiver circuitry for receiving over the second communications path in response to receiving the data indicative of the first request; reenable the receiver circuitry for receiving over the second communications path in response to receiving the data indicative of the second request.
