PROCESSING METHOD OF USER EQUIPMENT, PROCESSING METHOD OF MOBILITY MANAGEMENT ENTITY, USER EQUIPMENT, MOBILITY MANAGEMENT ENTITY, AND COMMUNICATIONS SYSTEM

摘要

The present invention relates to a processing method of a user equipment, including: detecting, by a user equipment in an active status, that user equipment capability of the user equipment has changed; and sending, by the user equipment, the changed user equipment capability of the user equipment to a base station. An embodiment of the present invention further provides a processing method of a mobility management entity, a user equipment, a mobility management entity, and a communications system. When the user equipment capability of the user equipment has changed, the user equipment can report the changed user equipment capability to the network side, so that the network side can timely save or stop saving power for the user equipment, thereby achieving a trade-off between power saving of the user equipment and the service quality.
