Terminal mode processing method, network access method and base station

A terminal mode processing method, a network access method and a base station are disclosed in the present invention. The terminal mode processing method includes that: a first base station using a first mode sends control information for indicating a multi-mode terminal to implement a second mode operation to the multi-mode terminal using the first mode (S102); the multi-mode terminal implements the second mode operation according to the control information (S104). The technical solution provided in the present invention significantly improves adaptability of the wireless communication system to a practical environment and ameliorates service quality and spectrum utilization rate of the wireless communication system.
