In NSA, the 5G base stations do not have an independent signaling plane, relying on the 4G base stations and the 4G core network.
However, in the initial stage of 5G network construction, due to practical problems such as technical capability and equipment cost, a non-independent networking scheme is temporarily adopted to erect the 5G network.

Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Currently, an EN-DC function is introduced in an LTE system, and a DC includes two cell groups: a Master Cell Group (MCG) and a Secondary Cell Group (SCG), wherein a base station managing the MCG is called a Master base station MeNB, and a base station managing the SCG is called a Secondary base station SeNB. The uplink data splitting fully utilizes resources of the MCG and SCG side base stations, so that the UE can use resources of the MeNB and/or SgNB to send uplink service data.
The following is a related description of the uplink data splitting in the protocol:
1. when the uplink Buffer data volume estimation and the Media Access Control (MAC) layer Buffer Status Report (BSR) Report of the UE are performed:
if the network side is configured with an uplink data distribution threshold and the data to be transmitted by the UE is greater than the threshold, the UE can indicate that data is to be transmitted to the MCG side and the SCG side; otherwise, the UE may indicate that there is data pending based on the configured path (path).
2. When a lower layer requests to deliver a Packet Data Convergence Protocol (PDCP) Data Packet, the UE: if the network side is configured with an uplink data distribution threshold and the data to be transmitted by the UE is greater than the threshold, the UE can submit the data to the MCG side or the SCG side; otherwise, the UE delivers the data based on the configured path.
According to the service data distribution mechanism of the protocol, a certain strategy is mainly designed to control the configuration of the uplink data distribution threshold and the uplink data distribution path, so that the UE can simultaneously use the resources of the MeNB and the SgNB to send the uplink service data under a certain condition, or only use one side of the MeNB/SgNB to send the uplink service data.
In the current shunting method, whether to dynamically shunt is determined based on the SRS channel state of a user only according to the good measurement (Signal to Interference plus Noise Ratio, SINR) on the SRS, which is considered as a good user, and the poor measurement of SINR, which is considered as a bad user, but the resource allocation mode of the SRS is different from that of the PUSCH channel and is influenced by the user data volume and the cell load, and the receiving Signal power of the SRS can not completely reflect the empty channel quality of the user on the PUSCH, so that the wireless resource can not be fully utilized, and the user perception is influenced.
In view of this, the present application provides an uplink data offloading method and apparatus, which adjust an uplink data offloading policy in combination with a load condition, a service data condition, and the like, so that radio resources can be fully utilized, and user perception can be improved.

and if the UE meets the first sub-condition and the second sub-condition, determining the shunting strategy of the uplink data as a first shunting strategy. That is, when the UE simultaneously satisfies the first sub-condition and the second sub-condition, the offloading policy of the uplink data is determined to be the first offloading policy.
And if the UE meets the first sub-condition, determining that the distribution strategy of the uplink data is a second distribution strategy. Namely, when the UE only satisfies the first sub-condition, the offloading policy of the uplink data is determined to be the second offloading policy.
In other embodiments of the present application, the different sub-conditions may further include: a third sub-condition and a fourth sub-condition.
And the third sub-condition is that the sum of the average value of the actual transmission level of the UE in the auxiliary cell group SCG and the expected value of the scheduling capability of the UE in the master cell group MCG cell is less than or equal to the average value of the scheduling capability of the UE in the SCG.

Preferably, the first offloading policy in this embodiment of the present application is to offload uplink data jointly through the MCG and the SCG; the second flow splitting strategy is to split the uplink data through the MCG or the SCG.
As shown in fig. 2, a flowchart for determining an uplink data offloading state provided in an embodiment of the present application is described in detail with reference to the flowchart shown in fig. 2. Taking the example that the MCG side sends the uplink data, firstly, whether the condition 1 is met is judged, if the condition 1 is met, the MCG side and the SCG side shunt the uplink data together, on the basis, whether the condition 2 is met is continuously judged, and if the condition 2 is met, the SCG side shunt data is adopted.
And if the condition 1 is not met, continuously judging whether the condition 3 is met, and if the condition 3 is met, adopting SCG side streaming data.
As can be seen from the above analysis, when the condition 2 or the condition 3 is satisfied, the SCG side divides the stream data, and on the basis, it can be continuously determined whether the condition 4 is satisfied, if the condition 4 is satisfied, the MCG and the SCG side collectively divide the upstream data, if the condition 4 is not satisfied, it is continuously determined whether the condition 5 is satisfied, and if the condition 5 is satisfied, the MCG side divides the stream data.
The following describes the details of the above-mentioned conditions 1 to 5.
Condition 1: (1) SCG cell signals meet the configurable condition; (2) BSRForAllLCG > -DataSplitThreshold 1; (3) avg (ueschrealinmcgcell) + ExpSchInScgCell < ═ avg (uesendcapapainmcgcell).

It is to be understood that condition 1 is the above-described first condition, and that (2) in condition 1 may correspond to the first sub-condition and (3) may correspond to the second sub-condition.
Condition 2:
Avg(UESchRealInMcgCell)+ExpSchInScgCell>Avg(UESendCapaInMcgCell)

It is understood that (2) in condition 3 is (2) in condition 1.
In the embodiment of the application, the conditions 1 to 3 take the service data condition of the UE into consideration, so that the offloading policy can be dynamically adjusted by combining the service data condition of the UE in the uplink data offloading process, thereby improving user perception.
Condition 4:

＝Avg(UESendCapaInScgCell)

Wherein, the PRBInCgCell is the number of PRBs corresponding to the cell bandwidth of the UE at Mcg; MinSINRInMcg is the minimum SINR threshold calculated by equivalent PRBs of the UE in Mcg cells, and the network side can be configured; the bandwidth ratio mainly takes the load condition of the LTE side into consideration, and the network side can be configured.
ul-DataSplitThreshold is set to DataSplitThreshold1 is configured for the UE.

As can be seen from the above judgment conditions, the condition 3 is a sub-condition of the condition 1, and the condition 2 is a condition opposite to the sub-condition of the condition 1. That is, when condition 3 or condition 2 is satisfied, SCG side shunting may be adopted, when condition 1 or condition 4 is satisfied, MCG and SCG may be adopted for shunting together, and when condition 5 is satisfied, MCG side shunting may be adopted, which may be specifically referred to as shown in fig. 3 and is a shunting diagram provided in the embodiment of the present application.
