Terminal capability reporting method, base station and terminal

The invention discloses a terminal capability reporting method, a base station and a terminal, wherein the method comprises the steps of: receiving terminal air interface capability information sent by the terminal after being successfully attached to a core network; according to the terminal air interface capability information, determining the first terminal air interface capability of the terminal; according to the determined terminal air interface capability, updating the second terminal air interface capability, wherein the second terminal air interface capability includes the terminal air interface capability reported by the terminal in a core network attaching process; and using the updated terminal air interface capability, wherein the terminal air interface capability sent by theterminal after being successfully attached to the core network is different from the terminal air interface capability reported by the terminal in the core network attaching process. According to theembodiment of the invention, after the terminal is successfully attached to the core network, when the terminal air interface capability needs to be changed, dynamic updating of the terminal air interface capability can be realized without interruption of terminal services; furthermore, the energy consumption of the terminal can be saved; and the load of the terminal can be reduced.
