The invention provides an algorithm and a system for data flow under an ENDC (E-UTRA NR Dual Connectivity,4G wireless access network and 5G NR dual connection) network according to the power consumption difference of a user terminal, and relates to network side equipment and a terminal. In the NSA mode, according to test and analysis, when the terminal transmits the packet service under the same coverage condition, the LTE is adopted to save most power, the secondary is SCG, and finally the MCG (Master Cell group, main cell group) +SCG is transmitted simultaneously. However, the data flow which can be borne by the MCG side is limited, partial packet service can be borne, the single bit power consumption of the SCG is the lowest, and the performance is the best. It is necessary to select an appropriate algorithm for data flow direction selection that balances the terminal power consumption and network performance.
As shown in fig. 2, the existing SCG adding scheme is as follows: after the terminal is accessed to the LTE side, B2 measurement is carried out, namely, neighbor cell measurement of an NR cell is carried out, when NR neighbor cell information is measured, the measured NR neighbor cell information is reported to the network side, and the network side carries out addition of an NR auxiliary node at the moment.
The existing data flow scheme is: before the network side does not receive the report of NR neighbor cell measurement, data transmission is carried out in LTE, when the network side receives the report of NR neighbor cell measurement and adds an NR auxiliary node, the data transmission is carried out in an NR cell when the data quantity is smaller than an N1 threshold, when the data quantity is larger than the N1 threshold, the data distribution is carried out, the data transmission is carried out in both LTE and NR cells, the data is preferentially transmitted in NR, and when the data cannot be carried, the data is transmitted in an LTE cell; or NR LTE split proportionally.
The existing SCG deletion scheme is: adopting an RRC inactivity timer mode, and releasing the SCG auxiliary node when NR cells continuously T s have no data; or adopting an A2 measurement mode, and releasing the SCG auxiliary node when the reference signal received power (Reference Signal Receiving Power, RSRP) of the NR cell is lower than a certain threshold.
The related art specifies that, as shown in fig. 3, the terminal may express some requirements of its own claims to the network side through UE ASSISTACE INFORMATION (terminal assistance information).
In the existing scheme, although SCG dual connection is easy to establish, load of LTE NR cells and influence of terminal power consumption are not considered during data distribution, SCG is difficult to delete, and influence on terminal power consumption is not considered.
The embodiment of the invention provides a method and a device for managing a secondary cell group, which can ensure network performance and reduce terminal power consumption.

and when the received data shunt transmission indication information reported by the terminal is a second preset value, carrying out shunt transmission of the data.

Optionally, performing the deletion of the secondary cell group includes: and deleting the secondary cell group when the value of the BSR reported by the terminal is continuously T seconds less than a fifth threshold and the value of the PDCP buffer reported by the terminal is continuously T seconds less than a sixth threshold.
In a specific embodiment, the network side device performs optimization of data flow, including SCG addition, data splitting and deletion.
Under NSA network, terminal carries out random access in LTE and establishes RRC connection, adding SCG increases power consumption of terminal, comprehensively considers influence of network performance and terminal power consumption, and comprehensively judges in consideration of time, B2 measurement report, terminal traffic and PRB utilization of LTE cell when SCG is added. The terminal generally has no need of emergency or high-rate service at night, and SCG cells can not be added in a certain period of time; the network side equipment reports and knows SCG cells which can be added by the terminal through B2 measurement, and when the PRB utilization rate of the LTE cells is high, the network performance is considered to need to add the SCG cells in time for load sharing. When the service volume of the terminal is small, the SCG can be added only when the LTE cell transmits to save power consumption and when the service volume is large, the LTE cannot bear the load to give consideration to the network performance. The specific implementation scheme is shown in fig. 10: firstly, judging whether an SCG auxiliary cell is added in a set time period, if not, judging whether B2 measurement report is received, and transmitting on the LTE side before the measurement report is not received, when the utilization rate of an uplink PRB (Physical Resource Block, a physical resource block) or a downlink PRB of the LTE cell is larger than a threshold W1 after the B2 measurement report is received, adding SCG, and judging the traffic of a terminal if the utilization rate of the uplink PRB or the downlink PRB is not larger than the threshold W1, wherein the traffic judging method comprises an uplink traffic judging method and a downlink traffic judging method when the traffic of the terminal reaches a certain threshold, and the uplink traffic judging method comprises the steps of: after an uplink service threshold M1 and a counter N1 are set in an MAC entity and a terminal reports a BSR (Buffer Status Report ), the MAC compares the value of the BSR with the threshold M1, when the BSR is continuously larger than the threshold M1 for N1 times, SCG is added, and if the situation that the BSR is smaller than the threshold M1 occurs before N1 times, the counter N1 is cleared; the flow of the downlink traffic judgment method is similar to that of the uplink traffic judgment method, and the MAC entity needs to set a downlink traffic threshold M2 and a counter N2 and needs to compare the PDCP buffer and the threshold M2. One of the uplink or downlink traffic satisfies the condition to add SCG.
After SCG is added, the same data volume is transmitted under the same coverage condition, and the power consumption condition of the terminal is NR < LTE < NR+LTE; considering the power consumption and network performance of a terminal, the judging basis of a data distribution transmission scheme is channel quality MCS and current traffic of the terminal, and the transmission principle is that data is transmitted only in NR or LTE as much as possible, wherein one side can save electricity and sleep through DRX when data transmission is carried out; when the traffic of the terminal cannot be carried on one side, the split transmission is carried out, and the transmission is carried out on the side with good channel quality preferentially. Since the channel quality has the greatest influence on the rate and the transmitting power of the terminal, the situation of the channel quality seriously affects the power consumption and the network performance of the terminal, and the transmission is preferentially performed on the side with good channel quality.
Because the option3x data is shunted on the NR side, the number of available PRBs and MCS on the LTE side are required to be transferred to the SCG through CG-ConfigInfo message, wherein the value range of the PRBs is the PRB maximum value corresponding to 1-bandwidth; the value range of the MCS is 1-28, the transmission is carried out periodically, and the transmission period is set as Ts. Specifically, the field name is McgPrbmcs { }, including McgPrb-UL, and the value range is { 1-N1 }; mcgPrb-DL, the value range is { 1-N2 }; mcgMcs-UL, the range of values is { 1-28 }; mcgMcs-DL, the range of values is { 1-28 }.
The scheme is as follows: after adding SCG, when there is data to be transmitted, judging once every Ts, firstly judging MCS of NR cell and LTE cell, transmitting data in cell with high MCS level preferentially, then judging whether current data quantity is smaller than threshold v, v is available PRB, MCS and data stream number of current cell, obtaining TBSIZE block according to PRB and MCS, for threshold v of uplink transmission, v up = TBSIZE up x percentage of uplink stream number, for threshold v of downlink transmission, v down = TBSIZE down x y percentage of downlink stream number; if the traffic is smaller than the threshold value v, the traffic is transmitted in the current cell only, otherwise, whether the other cell can bear the current traffic is judged, if so, the traffic is transmitted in the other cell, otherwise, the traffic is transmitted in the split transmission of the NR and LTE cells, the split transmission principle is that the traffic is transmitted in the current cell preferentially, and the excess traffic is transmitted in the other cell. When uplink and downlink data are transmitted simultaneously, judgment needs to be performed respectively.
Because the existence of SCG can increase the power consumption of the terminal, the deletion operation of SCG is performed when the terminal transmits small traffic, which is beneficial to the optimization of the power consumption of the terminal. Specifically, as shown in fig. 11, an A2 measurement manner may be adopted, and when the RSRP of the NR cell is lower than a certain threshold, the SCG auxiliary node is released; the method for judging the traffic of the UE in the NR cell can also judge the traffic of the UE in the NR cell, and release the NR cell, wherein the method for judging the traffic of the terminal comprises an uplink traffic judging method and a downlink traffic judging method, and the method for judging the uplink traffic comprises the following steps: setting an uplink service threshold M3 (M3 < M1) and time Ts in an NR MAC entity, after a terminal reports a BSR, comparing the value of the BSR with the threshold M3 by the MAC, deleting SCG when the continuous TS of the BSR is smaller than the threshold M3, and if the condition that the TS is larger than the threshold M3 before N3 times, recalculating the time; the flow of the downlink traffic judgment method is basically similar to that of the uplink traffic judgment method, and the MAC entity needs to set a downlink traffic threshold M4 (M4 < M2) and time Ts, and needs to compare the PDCP buffer and the threshold M4. Wherein, the up-link or down-link traffic can meet the condition to delete SCG.
