Frequency band replacing method and apparatus

The invention provides a frequency band replacing method and an apparatus. The method comprises the steps of receiving the identification information for identifying a second base station and sent from a terminal by means of a first base station when the strength of a wireless signal sent from the second base station within a first frequency band is larger than a threshold value, wherein the terminal is pre-accessed to the first base station and is in communication with the first base station within the first frequency band; according to the identification information, triggering the process of a frequency band replacing request to the second base station by the first base station. According to the technical scheme of the invention, the problem in the prior art that wireless communication services provided by multiple individuals or operators within the same frequency band during the wireless communication process are heavily interfered in communication effect can be solved. Furthermore, the effect of reducin
