The present invention discloses a communication mode switching method and device. The method comprises: receiving a sending request (S101); detecting whether the radio-frequency signal strength of a downlink channel meets a first threshold (S102); when the radio-frequency signal strength is greater than or equal to the first threshold, determining that a relay station is in a working state, and keeping a relaying mode to finish the sending request (S103); when the radio-frequency signal strength is less than the first threshold, determining that the relay station is in an abnormal state, and switching to an offline mode to finish the sending request (S104), the offline mode specifically being to perform sending after regulating the sending frequency to be the receiving frequency of the downlink channel. It can be seen that, whether the relay station is in the abnormal state is determined by detecting whether the signal strength of the downlink channel meets the preset threshold, and sequentially, the working mode is switched between the relaying mode and the offline mode in a targeted manner, so that when the relay station is in the abnormal state, the receiving frequency of the downlink channel is used as the sending frequency for sending signals, so as to ensure that other mobile stations are capable of receiving the sent signals, and the rate of call loss is lowered. |
