The NSA network Split Bearer partitioning involves many technical problems, and all the technical problems are relatively complex, and the most typical technical problems include: 1. intermodulation products or harmonic interference between Long Term Evolution (LTE) and New Radio (NR) frequency spectrums can deteriorate the channel quality on the two divided frequency spectrums, so that the throughput does not increase or decrease; 2. the problem of power sharing is that a terminal after bearing segmentation simultaneously transmits data on frequency spectrums of LTE and NR, if the power is limited before the segmentation, the unreasonable distribution of the power after the segmentation between a Secondary Node (SN) and a Master Node (MN) can cause that the throughput does not rise or fall; 3. the method has the advantages that the network load problem is solved, the anchor point of the user plane before bearing segmentation cannot acquire the resource use condition of the auxiliary node and the priority of the user to be segmented, the problem that the user after segmentation can not be scheduled exists possibly, the load of the auxiliary node is increased but cannot be benefited, and the load is not paid. The existing uplink bearer segmentation method of the NSA network belongs to the prepositive method, and a scheme which comprehensively considers all factors is difficult to find to ensure that the throughput can obtain gain after bearer segmentation. Therefore, how to determine whether the split bearer is reasonably divided becomes an urgent problem to be solved.

In order to enable those skilled in the art to better understand the handling method of split bearers according to the embodiment of the present invention, the following description is made.
The dual connectivity technology, which is an operation in which two User Equipments (UEs) in a radio resource control CONNECTED (RRC _ CONNECTED) state communicate using radio resources provided by at least two network nodes MN and SN CONNECTED through a non-ideal backhaul link, according to the definition of the third Generation Partnership Project (3 GPP), is one of effective means for providing users with transmission of data or signaling by using radio resources of multiple cells to meet specific requirements in different technical scenarios. The roles of the two network nodes in the dual connectivity are different, wherein the MN is a radio side anchor point of the UE, and provides the UE with a control plane connection unique to the core network, and the SN only provides the UE with additional radio resources for transmission of user data and signaling.
3GPP TR 38.801(Release-14) defines dual connectivity technology for LTE and NR, and presents a network architecture for possible LTE and 5G class 3, 8 (Option 3, 4, 7) NSAs. The Option 3/3a/3x has a common point that NR is a non-independent network, a control plane accesses an Evolved Packet Core (EPC) through an LTE eNB, an LTE base station (eNB) is a MN, and an NR base station (gNB) is an SN, which are different in that the established user plane bearers are different in types and data offloading manners, Option3 data is offloaded from the MN, Option 3a data is offloaded from the Core network, and Option3x data is offloaded from the Core network first and then from the SN. The Option7 system is similar to the Option3 system in protocol architecture, NR is not independent networking, LTE is MN, NR is SN, control plane connection mode is the same, user plane data distribution mode is the same, and the difference is that Option7 system Core network elements are upgraded from EPC to Next Generation Core Network (NGC), base station network elements are upgraded from LTE eNB to LTE eNB, and interfaces between base station network elements and Core network elements are upgraded from S1 port to NG port. The Option 4 is that NR is an independent networking, the connection modes of the control plane and the user plane are changed, NR is MN, and LTE is SN.
Compared with three bearer types of Master Cell Group (MCG) bearer, Secondary Cell Group (SCG) bearer and MCG split bearer in the conventional LTE dual connection, the SCG split bearer is newly added in the LTE-NR dual connection, and both Option3x and Option7x introduce the SCG split bearer. In order to support SCG bearer offloading, the 3GPP protocol defines relevant air interface parameters. Whether the uplink Split Bearer is Split is determined by the UE, if the UE detects that the amount of uplink data to be transmitted is less than the configuration threshold, the UE transmits the uplink data only on the Radio Access Technology (RAT) where the primary Path (primary Path) is located, and if the amount of uplink data to be transmitted is greater than the configuration threshold, the UE transmits the uplink data on the two RATs simultaneously.
Uplink bearer segmentation methods for SCG split bearers are roughly classified into three types: bearer segmentation based on traffic triggering, bearer segmentation based on measurement triggering, bearer segmentation based on service delay requirement triggering. The simplest scheme for triggering bearing segmentation based on the service volume is that all users configure the same segmentation threshold, the segmentation is completely determined by the service volume requirement of the users, the method of the complex point can dynamically adjust the bearing segmentation threshold of the users by combining the network load and the service volume of the users, and the users and the network are expected to realize throughput improvement at the same time; the simple scheme of bearing segmentation based on measurement triggering is that the quality of an uplink signal is divided into a plurality of grades according to the strength of the uplink signal measured by a base station, different bearing segmentation thresholds are configured at different grades, the bearing segmentation thresholds are dynamically adjusted according to the real-time measurement result of a user, the bearing segmentation is realized to the maximum extent, and the service volume requirement of the user is met to the maximum extent.
As shown in fig. 1, an embodiment of the present invention provides a method for processing a split bearer, which is applied to a secondary node SN, and the method includes:
step 101: acquiring the throughput of a first Packet Data Convergence Protocol (PDCP) layer before SCG separation bearer segmentation of the auxiliary cell group, wherein the first PDCP layer throughput refers to the PDCP layer throughput of an SN side of the auxiliary node in a first preset statistical time.
Step 102: and acquiring the throughput of a second PDCP layer after SCG separation bearer segmentation, wherein the throughput of the second PDCP layer refers to the throughput of the PDCP layers of the MN side and the SN side of the main node in a second preset statistical duration.
Step 103: and comparing the first PDCP layer throughput with the second PDCP layer throughput, and determining the segmentation processing result of the SCG separation bearer, wherein the segmentation processing result comprises the segmentation state of keeping the SCG separation bearer or the segmentation state of backing up the SCG separation bearer.
Specifically, it is evaluated whether the current bearer split is reasonable or not by comparing the rate difference in a period of time before and after the SCG split bearer split in the NR PDCP network element device, and whether the split bearer needs to be returned to only the service transmission on the auxiliary node SN, for example, the bearer in the split state is returned to the state before split.
The method for processing the separation bearer according to the embodiment of the present invention determines the result of the segmentation processing of the SCG separation bearer by comparing the throughput of the first PDCP layer before the SCG separation bearer is segmented with the throughput of the second PDCP layer after the SCG separation bearer is segmented, and can determine whether the segmentation of the SCG separation bearer is reasonable according to the result of the segmentation processing, and further determine whether to perform the fallback processing on the segmentation of the SCG separation bearer, so as to avoid the prior bearer segmentation method from causing the throughput of the user not to increase and decrease and waste of network air interface resources, and simultaneously avoid the virtual consumption of the terminal battery due to unreasonable bearer segmentation.
Further, comparing the first PDCP layer throughput with the second PDCP layer throughput, and determining a result of the segmentation process of the SCG separated bearer, includes:
and comparing the throughput of the first PDCP layer with the throughput of the second PDCP layer to obtain a comparison result.
The comparison result includes that the second PDCP layer throughput is greater than or equal to the first PDCP layer throughput, or that the second PDCP layer throughput is less than the first PDCP layer throughput.
Updating target parameters according to the comparison result, wherein the target parameters comprise first parameters or comprise the first parameters and second parameters; the first parameter represents a number of cumulative comparisons of the second PDCP layer throughput with the first PDCP layer throughput, and the second parameter represents a number of times the second PDCP layer throughput is greater than or equal to the first PDCP layer throughput.
Specifically, when the comparison result is that the second PDCP layer throughput is greater than or equal to the first PDCP layer throughput, the first parameter and the second parameter are updated; and updating the first parameter when the comparison result shows that the second PDCP layer throughput is less than the first PDCP layer throughput.
Furthermore, when the comparison result is that the throughput of the second PDCP layer is greater than or equal to the throughput of the first PDCP layer, the value corresponding to the first parameter is added with 1, and when the comparison result is that the throughput of the second PDCP layer is less than the throughput of the first PDCP layer, the value corresponding to the first parameter is added with 1, and the value corresponding to the second parameter is unchanged.
And determining a segmentation processing result of the SCG separation bearer according to the relation between the target parameter and a preset threshold value.
Specifically, when the value of the first parameter is smaller than a first preset threshold and the value of the second parameter is greater than a second preset threshold, it is determined that the segmentation processing result of the SCG split bearer is to maintain the segmentation state of the SCG split bearer, and the first preset threshold is greater than the second preset threshold.
Determining a segmentation processing result of the SCG separation bearer according to the relation between the target parameter and a preset threshold, wherein the segmentation processing result comprises the following steps:
under the condition that the value of the first parameter is smaller than a first preset threshold value and the value of the second parameter is smaller than a second preset threshold value, the throughput of the second PDCP layer is obtained again; and comparing the throughput of the first PDCP layer with the throughput of the second PDCP layer which is obtained again to obtain a comparison result, and executing the step of updating the target parameter according to the comparison result.
