Description

Control method and device of terminal equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling a terminal device, and a storage medium.

Background

Under a multi-connection scenario, the cells are divided into a Master Cell Group (MCG) and one or more Secondary Cell Groups (SCGs), where the Cell Group on the Master Node (MN) side is called a Master Cell Group and generally consists of one Master Cell (Primary Cell, PCell) and one Secondary Cell (Secondary Cell, SCell) (Secondary cells are not essential items). A Cell group on the Secondary Node (SN) side may be referred to as a Secondary Cell group, and is also composed of a Primary Cell (PSCell) and a Secondary Cell (SCell).

In some application scenarios, in view of energy saving, a terminal device (e.g., a User Equipment, UE) may set an SCG side to a deactivated state (deactivated) when a data transmission amount is small, and in the deactivated state, the UE does not monitor a Physical Downlink Control Channel (PDCCH) of the SCG side, does not transmit a Physical Uplink Shared Channel (PUSCH), does not transmit data of an auxiliary cell group SCG side, but may still perform measurement and reporting of Radio Resource Management (RRM).

The Timing Advance (TA) is used for controlling uplink data transmission of the UE, and the TA is a system frame in which the UE transmits uplink data, and is advanced by a certain Time compared with a corresponding downlink frame. The Timing Advance Timer (TAT) is a Timer for controlling TA, and if the TAT is overtime, the UE may perform a Random Access Channel (RACH) procedure to obtain TA.

In the related art, when activating the secondary cell group SCG, the terminal device may maintain synchronization with the network when the TAT of the PSCell on the SCG side is not timed out; it may also be out of synchronization with the network due to the fast moving speed of the terminal device, etc. How to ensure the stable communication between the terminal device and the network device becomes a problem to be solved urgently.

For example, an activation instruction sent by the network device may be received by the terminal device, where the activation instruction is used to instruct to activate the target secondary cell group SCG, that is, to set the target SCG from a deactivated state (activated) to an activated state (activated).

S102: it is determined whether the timing advance time TAT of the target SCG has timed out.

In the embodiment disclosed in the present application, when receiving an activation instruction sent by a network device, the UE may detect a timing advance time TAT of a target SCG in real time, where the timing advance time TAT is a timer for controlling a TA, and if the timing advance time TAT is overtime, the UE may perform a Random Access Channel (RACH) procedure to reacquire the timing advance TA, and update an existing timing advance TA according to the reacquired timing advance TA, and if the timing advance time TAT is not overtime, may trigger execution of a subsequent step.

The determining whether the timing advance time TAT of the target SCG is overtime may specifically be determining whether the timing advance time TAT of the target SCG is overtime in a process of setting a state of the target SCG according to the activation instruction, so that timeliness of control of the terminal device can be effectively improved.

For example, when the state of the target SCG is set from the deactivated state to the activated state according to the activation instruction, whether the timing advance time TAT of the target SCG is timed out may be determined in real time.

S103: and if the TAT is not overtime, starting a designated timer, wherein the designated timer is used for judging whether the desynchronization between the terminal equipment and the network equipment occurs.

For configuration of the designated timer, reference may be specifically made to an embodiment on the network device side, which is not described herein again.

That is, if the specified timer is overtime (for example, the time counted by the specified timer exceeds the timing time), it may be directly determined that the terminal device and the network device are out of synchronization, so as to trigger the terminal device to perform the subsequent steps, and timely avoid the influence of the out-of-synchronization of the terminal device and the network device on the communication stability.

S104: and if the designated timer is overtime, triggering to execute the designated operation.

That is to say, in this embodiment of the present application, a designated timer may be configured in advance to assist in determining a timing for triggering a terminal device to execute a designated operation, and when an activation instruction for instructing to activate a target auxiliary cell group SCG sent by a network device is received and a timing advance time TAT of the target SCG is not expired, the timing for triggering the terminal device to execute the designated operation is determined according to the designated timer, and the designated timer is used to determine whether step-out occurs between the terminal device and the network device, when the designated timer is expired, it may be determined that the terminal device and the network device may have step-out or a probability of determining that step-out occurs is relatively high, at this time, in order to ensure stability of communication between the terminal device and the network device, the terminal device triggers to execute the designated operation, thereby effectively avoiding an influence of step-out between the terminal device and the network device on communication stability.

In this embodiment of the application, if the TAT is not overtime, the terminal device may have at least one or more of the following operations: the terminal device monitors a physical downlink control channel PDCCH, and/or transmits uplink data in the configured uplink resource, which is not limited.

Therefore, in the embodiment disclosed by the application, when the TAT is not timed out, the appointed timer is directly started; or, when the TAT is not overtime and the monitoring of the physical downlink control channel PDCCH is determined to start, starting a designated timer; or, when the TAT is not overtime and after the terminal device sends the uplink UL signal/signaling/data, the designated timer is started, thereby providing a flexible way of starting the designated timer, so that the control method of the terminal device disclosed in the present application can have better applicability, and assist in accurately and timely starting the designated timer.

After starting the designated timer, it is determined whether the designated timer has timed out, and if so, the terminal device may perform any one or more of the following operations S204, S205, S206, and S207.

S205: and if the designated timer is overtime, sending a first message to the network equipment, wherein the first message is used for indicating that the target SCG has a radio link failure event.

For example, if the designated timer is overtime, the control terminal device sends a first message to the network device, where the first message is used to indicate that a radio link failure event occurs in the target SCG, and then may wait for the network device to make a decision.

For another example, when the specified timer is overtime, and the terminal device does not receive the PDCCH, and/or the terminal device does not receive the downlink message fed back by the network device, the terminal device may be controlled to send the first message to the network device.

S206: and if the designated timer is overtime, maintaining the target SCG in an activated state according to the activation instruction.

For example, if the designated timer expires, the target SCG is maintained in the active state according to the active command.

For another example, when the designated timer expires and the terminal device does not receive the PDCCH and/or the terminal device does not receive the downlink message fed back by the network device, the target SCG may be maintained in the active state according to the activation instruction.

S207: and if the designated timer is overtime, setting the target SCG to be in a deactivated state, and sending a second message to the network equipment, wherein the second message is used for indicating that the target SCG is not successfully activated.

For example, if the designated timer is over, the target SCG is set to be in a deactivated state, and a second message is sent to the network device, where the second message is used to indicate that the target SCG is not successfully activated, and then, the network device may wait for a decision.

For another example, when the specified timer is overtime and the terminal device does not receive the PDCCH and/or the terminal device does not receive the downlink message fed back by the network device, the target SCG may be set to the deactivated state, and a second message may be sent to the network device, and then, the network device may wait for the decision.
