Description

Activation or deactivation method, apparatus and device of secondary node or secondary cell

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on the Chinese patent application with the application number of 202010837198.4 and the filing date of August 19, 2020, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby incorporated by reference into this application.

technical field

The present application relates to the field of communication technologies, and in particular, to a method, apparatus, device, and storage medium for activating or deactivating a secondary node or a secondary cell.

Background technique

Currently, dual connectivity supports processes such as SN (Secondary Node, secondary node) addition initiated by the MN (Master Node, primary node), SN modification initiated by the MN or SN, and SN release initiated by the MN or SN.

Activation and deactivation of SCG (Secondary Cell Group, secondary cell group) is a mechanism that can speed up the workflow of dual connectivity. Due to the large power consumption of the terminal in the dual-connection state, if the service rate of the UE (User Equipment, user equipment) decreases after the SN is added, the SN/PSell can be kept in the pending (suspended) state, that is, the context configuration information of the UE is maintained. without releasing the SN. In this way, when the UE resumes the high data rate service, the dual-connection communication can also be resumed in time, thereby improving the service experience of the UE.

The processes of adding, modifying, releasing, and activating and deactivating dual connections in the above-mentioned existing mechanism are all controlled by the network side, that is, the MN or SN is triggered according to the experience of the network side and other implementations. When the UE is triggered by a large number of uplink services, such as uploading video and other applications, if the network side cannot sense it in time, the dual-connection activation may not be timely enough, so that the UE cannot use the dual-connection in time, affecting the service experience; similarly When the uplink service of the UE falls, such as the completion of video uploading, if the network side cannot sense it in time, the deactivation of the dual connection may not be timely enough, so that the UE cannot restore the single connection in time, which increases the power consumption of the UE.

The processes of adding, modifying, releasing, and activating and deactivating dual connections in the related art are all controlled by the network side, that is, triggered by the MN or SN according to the experience of the network side and other implementations. When the UE has a large number of uplink services or low-latency and high-reliability services triggered, such as uploading videos, starting applications such as low-latency and high-reliability, if the network side cannot sense it in time, the dual-connectivity activation may not be timely enough, resulting in the UE not being able to be timely. Using dual connections will affect service experience; similarly, when the UE has to fall back on uplink services, such as video uploading, or the terminal has insufficient power and needs to save power, the network side cannot sense it in time, which may lead to insufficient deactivation of dual connections. The UE cannot restore the single connection in time, which increases the power consumption of the UE. Therefore, the embodiments of the present application provide a UE-initiated SN/PScell activation and deactivation mechanism, which helps the UE to realize dual connectivity or de-dual connectivity as soon as possible, thereby improving user experience and saving UE power consumption.

Referring to FIG. 9, FIG. 9 is a flowchart of a method for activating a secondary node or a secondary cell according to an embodiment of the present application. As shown in Figure 9, the method may include:

For example, the UE may send an activation request to the MN.

Exemplarily, the request may be sent through an RRC (Radio Resource Control, radio resource control) message or a MAC (Medium Access Control, medium access control) CE (Control Element, control unit). Among them, the activation request can carry:

Reasons for the UE requesting activation: such as the conditions configured on the network side are met, the UE needs to save power, match the data rate or service requirements of the UE, the quality of the SN/PScell measured by the UE is too poor, etc.;

The length of time that the UE requests to activate Timer1: the length of time is the length of time that the UE determines to be activated according to its own uplink service, power, etc.;

Step 903: The network device sends activation confirmation information to the UE.

For example, the MN sends activation confirmation information to the UE.

Optionally, the activation confirmation information can also carry:

Confirmation or adjustment instruction for the requested activation time Timer1: The MN makes a pre-judgment according to the situation of the downlink service of the UE, determines that the duration of this activation is Timer2, and notifies the UE.

There may be one or more identifiers related to the activated secondary cell or secondary node.

The number of buffers of the UE UL (such as the number of buffers of PDCP or RLC, or the sum of the number of buffers of PDCP and RLC) is lower than a certain threshold (indicating that the data traffic volume is not large).

The uplink data packet delay of the UE is lower than the preset threshold;

The UE receives the instruction from the upper layer.
