Abstract
Disclosed in embodiments of the present disclosure are a transition method, a network device, and a terminal device. The method includes: receiving, by a network device, supporting information associated with a terminal device which is sent from the terminal device; determining, by the network device, a target state of the terminal device to be transitioned to according to the supporting information, wherein the target state is a Radio Resource Control (RRC) idle state or an RRC inactive state; and enabling, by the network device, the terminal device to transition to the target state.
Claims12
A transition method, comprising:
- sending, by a network device, indication information to a terminal device, the indication information being used to indicate that there is currently no downlink data to be transmitted;
- after sending the indication information, receiving, by the network device, supporting information associated with the terminal device which is sent from the terminal device;
- determining, by the network device, a target state of the terminal device to be transitioned to according to the supporting information, wherein the target state is a Radio Resource Control (RRC) idle state or an RRC inactive state;
- and
- enabling, by the network device, the terminal device to transition to the target state;
- wherein the supporting information comprises mobile state information of the terminal device and arrival time interval information of a current service of the terminal device;
- wherein determining, by the network device, a target state of the terminal device to be transitioned to according to the supporting information, comprises:
- determining, by the network device, the target state according to the mobile state information and/or the arrival time interval information;
- wherein determining, by the network device, the target state according to the mobile state information comprises:
- if a moving speed of the terminal device is greater than or equal to a first threshold, determining by the network device that the target state is the RRC idle state;
- and
- if the moving speed of the terminal device is smaller than the first threshold, determining by the network device that the target state is the RRC inactive state;
- wherein enabling, by the network device, the terminal device to transition to the target state, comprises:
- if the target state is the RRC idle state, releasing by the network device all radio bearers between the terminal device and the network device;
- and
- if the target state is the RRC inactive state, releasing by the network device a part of the radio bearers between the terminal device and the network device.

A network device, comprising:
- a processor;
- a memory for storing instructions executable by the processor;
- an input interface configured to send indication information to a terminal device, the indication information being used to indicate that there is currently no downlink data to be transmitted, and after the indication information is sent, receive supporting information associated with the terminal device which is sent from the terminal device;
- wherein the processor is configured to:
- determine a target state of the terminal device to be transitioned to according to the supporting information, wherein the target state is a Radio Resource Control (RRC) idle state or an RRC inactive state;
- and
- enable the terminal device to transition to the target state;
- wherein the supporting information comprises mobile state information of the terminal device and arrival time interval information of a current service of the terminal device;
- wherein the processor is configured to:
- determine the target state according to the mobile state information and/or the arrival time interval information;
- wherein determining the target state according to the mobile state information comprises:
- if a moving speed of the terminal device is greater than or equal to a first threshold, determining that the target state is the RRC idle state;
- and
- if the moving speed of the terminal device is smaller than the first threshold, determining that the target state is the RRC inactive state;
- wherein the processor is configured to:
- if the target state is the RRC idle state, release all radio bearers between the terminal device and the network device;
- and
- if the target state is the RRC inactive state, release a part of the radio bearers between the terminal device and the network device.
