Provided are a service detection method when an LTE system operates on an unauthorized frequency band, a service detection system when an LTE system operates on an unauthorized frequency band, a terminal, and a base station. The service detection method when an LTE system operates on an unauthorized frequency band comprises: detecting whether a target detection signal exists on a current subframe of the unauthorized frequency band, so as to confirm whether a base station providing a service to the terminal has occupied an idle channel; when the target detection signal is detected, confirming that the base station has occupied the idle channel, so that the base station executes service scheduling on the unauthorized frequency band; and when the target detection signal is not detected, continuing to detect whether the target detection signal exists on subframes following the current subframe. By means of the technical solution, energy consumption of a terminal can be effectively reduced, and a position where a base station successfully occupies a channel can be learned accurately while achieving the purpose of energy saving, so that the case where the terminal misses a scheduling chance can be avoided effectively. |
