## Abstract

A method for controlling a state of a terminal includes: triggering the terminal to enter a first state in a case that a first condition is met or a network indication is received, where power consumption of the terminal in the first state is less than power consumption of the terminal in a connected state, an idle state, or an inactive state.

a radio resource control (RRC) state of the terminal at a radio access network (RAN) side; or

### Claim 5 (depends on 3)

The method according to claim 3, wherein in a case that the first state is the RRC state other than the first RRC state, the terminal executes at least one of:
invalidating some or all of RAN configuration information in the RRC idle state;
maintaining some or all of core network configuration information in the CM idle state to continue taking effect; or
maintaining registration information on a core network unchanged.

### Claim 6 (depends on 3)

The method according to claim 3, wherein in a case that the first state is the sub-state of the RRC idle state, the terminal executes at least one of:

the configuration information in the idle state comprises at least one of access network configuration information or core network configuration information.

### Claim 7 (depends on 1)

The method according to claim 1, wherein in a case that the first state belongs to the RRC state and the CM state, some or all of configuration information of the terminal in the idle state takes no effect, wherein
the configuration information of the terminal in the idle state comprises at least one of access network configuration information or core network configuration information.

### Claim 8 (depends on 7)
