Abstract

A method for state control of a user equipment includes: when in an inactive state, sending, a state indication message for indicating that the UE needs to switch to a connection state, to a base station, upon detecting that a preset state switching event is triggered; switching to the connection state according to a state switching instruction returned by the base station. The preset state switching event includes at least one of: a bearer corresponding to traffic data to be sent or received by the UE does not belong to a designated bearer that is a bearer capable of transmitting the service data in the inactive state; a message to be sent by the UE is a NAS message; a data buffer size of the UE exceeds a first threshold; and an RSRP value of a reference signal sent by the base station is less than a second threshold.

1. A method for controlling states of a user equipment (UE), applied to the UE, the method comprising:

detecting whether a preset state switching event is triggered, when the UE is in an inactive state;

sending, a state indication message for indicating that the UE needs to switch to a 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;

switching 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;

a message to be sent by the UE is a non-access stratum (NAS) message;

a data buffer size of the UE exceeds a first threshold;

a reference signal receiving power (RSRP) value of a reference signal sent by the base station is less than a second threshold; and

a bearer corresponding to traffic data to be received by the UE does not belong to the designated bearer.

2. The method of claim 1, wherein the preset state switching event comprises that the bearer corresponding to the traffic data to be received by the UE does not belong to the designated bearer, and wherein detecting that whether the preset state switching event is triggered comprises:

when a first paging message sent by the base station is received, determining that the preset state switching event is triggered, wherein the first paging message carries state switching information for indicating that the bearer corresponding to the traffic data to be received by the UE does not belong to the designated bearer; and

when a second paging message sent by the base station is received, determining whether the bearer corresponding to the traffic data to be received belongs to the designated bearer, according to a traffic type of the traffic data carried in the second paging message;

if the bearer corresponding to the traffic data to be received does not belong to the designated bearer, determining that the preset state switching event is triggered.

3. The method of claim 1, wherein sending the state indication message to the base station comprises:

generating switching reason information according to the triggered preset state switching event; and

sending the switching reason information carried in the state indication message to the base station, wherein the state switching instruction is returned by the base station according to the switching reason information.

4. The method of claim 1, wherein:

when the preset state switching event comprises the bearer corresponding to the traffic data to be sent by the UE does not belong to the designated bearer, or comprises the bearer corresponding to the traffic data to be received by the UE does not belong to the designated bearer,

prior to detecting that whether the preset state switching event is triggered, the method further comprises;

receiving 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;

entering the inactive state according to the inactive state instruction, and storing the configuration information of the designated bearer; and

performing the step of detecting whether the preset state switching event is triggered according to the configuration information of the designated bearer.

5. A method for controlling states of a user equipment (UE), applied to a base station, the method comprising:

receiving a state indication message, wherein the state indication message is sent by the UE upon detecting that a preset state switching event is triggered;

generating a state switching instruction for instructing the UE to switch to a connection state, according to the state indication message; and

sending the state switching instruction to the UE.

6. The method of claim 5, wherein generating the state switching instruction according to the state indication message comprises:

determining whether to allow the UE to switch to the connection state according to switching reason information;

generating the state switching instruction, when the UE is allowed to switch to the connection state.

7. The method of claim 5, further comprising:

sending a first paging message to the UE, when a bearer corresponding to traffic data to be sent by a base station does not belong to a designated bearer that is a bearer capable of transmitting traffic data in an inactive state, wherein the first paging message carries state switching information for indicating that the bearer corresponding to the traffic data does not belong to the designated bearer; and

sending a second paging message to the UE, when the bearer corresponding to the traffic data to be sent by the base station does not belong to the designated bearer, wherein the second paging message carries a traffic type of the traffic data.

8. The method of claim 5, wherein prior to receiving the state indication message, the method further comprises:

obtaining configuration information of the designated bearer that is a bearer capable of transmitting traffic data in an inactive state, wherein the configuration information of the designated bearer is used to indicate a traffic type of traffic data corresponding to the designated bearer; and

sending, an inactive state instruction carrying the configuration information of the designated bearer, to the UE.

9. 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 when 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;

a message to be sent by the UE is a non-access stratum (NAS) message;

a data buffer size of the UE exceeds a first threshold;

a reference signal receiving power (RSRP) value of a reference signal sent by the base station is less than a second threshold; and

a bearer corresponding to traffic data to be received by the UE does not belong to the designated bearer.

10. The user equipment of claim 9, wherein the preset state switching event comprises that the bearer corresponding to the traffic data to be received by the UE does not belong to the designated bearer, and wherein the processor is further configured to:
