[0112] Step 11. The network side device sends configuration information of separated bearer to the terminal, and the configuration information includes:
[0113] The separation bears configuration information of associated N RLC entities, where N (N>=3) RLC entities belong to different cell groups, for example: N RLCs belong to MCG and SCG respectively;
[0114] Multiple split bearer thresholds, for example: the first split bearer threshold (thresh_1) and the second split bearer threshold (thresh_2), and thresh_1
[0115] A list of association relationships between the bearer threshold and the transmission path is separated.
[0116] Wherein, the association relationship list between the separated bearer threshold and the transmission path includes the following information:
[0117] Each separate bearer threshold corresponds to one or more transmission paths, and the number of transmission paths associated with each separate bearer threshold is less than N;

Abstract
The invention provides a control method of a split bearer and related equipment. The control method of the split bearer comprises the steps that a terminal is configured with a target split bearer, the target split bearer comprises N transmission paths, and N is a positive integer greater than 2; an available transmission path set in the N transmission paths is determined based on a to-be-transmitted uplink data volume and a split bearer threshold of the target split bearer, wherein the available transmission path set is the N transmission paths or a transmission path set associated with the split bearer threshold; and uplink data transmission is performed through a target transmission path in the available transmission path set. According to the control method of the split bearer providedby the embodiment of the invention, the terminal can select the transmission path for transmitting the uplink data more flexibly, so that the possibility of always selecting the same transmission path to perform uplink data transmission can be reduced, and the resource utilization rate of the terminal is further improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method for controlling separated bearers and related equipment. Background technique [0002] With the development of mobile communication technology, mobile communication systems such as 5G (5th-Generation, fifth generation) systems use a dual connectivity (Dual Connectivity, DC) architecture for data transmission. In the DC architecture of the 5G system, the master cell group (Master Cell Group, MCG) of the terminal (UserEquipment, UE) uses the resources of the master node (Master Node, MN) on the network side, and the secondary cell group (Secondary Cell Group, SCG) Resources of a secondary node (SecondaryNode, SN) on the network side are used. [0003] In the DC architecture, the network side can configure the radio bearer (Radio Bearer, RB) of the terminal as a split bearer (Split Bearer), and the split bearer includes two transmission paths, different tran...
