Message transmission electricity saving method and relevant equipment

The embodiment of the invention discloses a message transmission electricity saving method, which comprises the following steps that when a user terminal is in a wireless resource control connection state, the user terminal sends current operation state information of the user terminal to a base station so that the base station judges whether to activate or invalidate the message transmission capability of the user terminal according to the operation state information and returns a wireless resource control signaling carrying transmission instruction information to the user terminal; the user terminal receives the wireless resource control signaling carrying the transmission indication information sent by the base station; the user terminal controls the message transmission of the user terminal and a vehicle-mounted terminal according to the transmission indication information. The embodiment of the invention also discloses a message transmission electric saving device. By using the embodiment of the invention, the electric quantity consumption of the message transmission of the user terminal can be reduced.
