Methods and devices for controlling states of user equipment

A user equipment (UE), comprising:

• a processor;
• a non-transitory storage configured to store processor executable instructions;
• wherein the instructions cause the processor to:
• detect whether a preset state switching event is triggered, wherein the UE is in an inactive state;
• send, a state indication message for indicating that the UE needs to switch to the connection state, to a base station, upon detecting that the preset state switching event is triggered, wherein a state switching instruction for instructing the UE to switch to the connection state is returned by the base station according to the state indication message;
• switch from the inactive state to the connection state according to the state switching instruction;
• wherein the preset state switching event comprises at least one of the followings:
• a bearer corresponding to traffic data to be sent by the UE does not belong to a designated bearer that is a bearer capable of transmitting traffic data in the inactive state;
• and
• a bearer corresponding to traffic data to be received by the UE does not belong to the designated bearer;
• wherein the processor is further configured to:
• prior to detecting whether the preset state switching event is triggered,
• receive an inactive state instruction of the base station, wherein the inactive state instruction comprises configuration information of the designated bearer for indicating a traffic type of traffic data corresponding to the designated bearer;
• enter the inactive state according to the inactive state instruction, and storing the configuration information of the designated bearer;
• and
• perform the step of detecting whether the preset state switching event is triggered according to the configuration information of the designated bearer.
