1. A method for wireless communication, comprising:
sending, by a radio resource control (RRC) layer of a terminal device, indication information to a non-access stratum (NAS) of the terminal device, wherein the indication information comprises first state indication that is used for indicating a first RRC state of the RRC layer; and
transferring, by the NAS of the terminal device according to the first state indication, the NAS of the terminal device to a first NAS state,
wherein the first RRC state of the RRC layer comprises an RRC idle state with suspend indication and an RRC inactive state, and RRC connection of the terminal device is suspended in both the RRC idle state with suspend indication and the RRC inactive state,
in response to that the indication information indicates the RRC layer being in the RRC idle state with suspend indication, the NAS is transferred to an idle state with suspend indication; and
in response to that the indication information indicates the RRC layer being in the RRC inactive state, the NAS is transferred to a connected state with inactive indication.
 
5. A terminal device, comprising:
a processor; and
a memory for storing a computer program,
wherein the processor is configured to call and run the computer program stored in the memory to perform operations of:
sending, at a radio resource control (RRC) layer, indication information to a non-access stratum (NAS) of the terminal device, wherein the indication information comprises first state indication that is used for indicating a first RRC state of the RRC layer; and
transferring, at the NAS, the NAS of the terminal device to a first NAS state according to the first state indication,
wherein the first RRC state of the RRC layer comprises an RRC idle state with suspend indication and an RRC inactive state, and RRC connection of the terminal device is suspended in both the RRC idle state with suspend indication and the RRC inactive state,
in response to that the indication information indicates the RRC layer being in the RRC idle state with suspend indication, the NAS is transferred to an idle state with suspend indication; and
in response to that the indication information indicates the RRC layer being in the RRC inactive state, the NAS is transferred to a connected state with inactive indication.
 
9. A non-transitory computer-readable storage medium for storing a computer program that, when running on a computer, causes the computer to perform operations of:
sending, by a radio resource control (RRC) layer of a terminal device, indication information to a non-access stratum (NAS) of the terminal device, wherein the indication information comprises first state indication that is used for indicating a first RRC state of the RRC layer; and
transferring, by the NAS of the terminal device according to the first state indication, the NAS of the terminal device to a first NAS state,
wherein the first RRC state of the RRC layer comprises an RRC idle state with suspend indication and an RRC inactive state, and RRC connection of the terminal device is suspended in both the RRC idle state with suspend indication and the RRC inactive state,
in response to that the indication information indicates the RRC layer being in the RRC idle state with suspend indication, the NAS is transferred to an idle state with suspend indication; and
in response to that the indication information indicates the RRC layer being in the RRC inactive state, the NAS is transferred to a connected state with inactive indication.
