In the NSA, the UE simultaneously maintains 4G and 5G links, that is, the UE is provided with two sets of radio frequency systems, one set of radio frequency system is used for implementing a 4G network, and the other set is used for implementing a 5G network.

In order to avoid the problem that the power consumption of the UE increases and the overall transmission speed cannot reach the 5G standard, embodiments of the present invention provide a radio frequency system control method, apparatus, terminal, and storage medium, and the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present invention. In the application scenario, the method comprises the following steps:

4G Core network (EPC), 4G base station (eNB), gNB, and UE.

Currently, the communication process between the UE in the NSA structure and the EPC network includes: the UE establishes a communication link with the eNB and the gNB simultaneously, when the UE sends data to the EPC network, the UE divides the data in a data packet to be sent into two parts, one part of the data is sent to the eNB through the LTE link, the other part of the data is sent to the gNB through the NR link, and finally, the eNB and the gNB jointly transmit the data to the EPC network, so that the data transmission between the UE and the EPC network is realized. In this communication method, the NR link is always on, which results in higher power consumption.

The UE may be a mobile phone, a tablet computer, a wearable device, or a notebook computer.

The application scenarios described above are merely examples of application scenarios for implementing the embodiments of the present application, and the embodiments of the present application are not limited to the application scenarios described above.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a schematic flowchart of a radio frequency system control method provided in an embodiment of the present invention, which is applied to the UE using NSA, and as shown in fig. 2, the method may include:

step 201: and if the radio frequency system corresponding to the NR of the UE is in an opening state, determining the NR TBS.

In this embodiment, if the radio frequency system corresponding to the NR of the UE is in an on state, that is, the UE is in a dual link mode, and the NR link is on, the power consumption of the UE is high at this time, and if the 5G transmission capability is poor, it is not necessary to turn on the NR link, which wastes the power consumption of the UE. Based on this, the current 5G transmission capacity needs to be determined.

The TBS is a direct reflection of the downlink transmission rate of the network, and characterizes the current network transmission capability, so the NR TBS needs to be determined first.

Referring to fig. 3, in some embodiments, the NR TBS may be determined by:

step 301: the UE obtains a Channel Quality Indicator (CQI) by measuring a Cell Reference Signal (CRS);

step 302: the UE reports the CQI to the gNB;

step 303: the gNB looks up a table according to a Channel Quality Indicator index (CQIindex) to obtain modulation (modulation);

step 304: the gNB calculates a modulation and coding strategy index (MCS index) according to the CQI index;

step 305: the gNB looks up a table according to the MCS index to obtain a Transport block size index (TBS index);

step 306: the gNB calculates the Number of Physical Resource Blocks (NPRB), and further calculates and checks the code rate;

step 307: the gNB indicates the MCS and the NPRB to the UE through the DCI;

step 308: the UE looks up the table based on the DCI to obtain the NR TBS.

Step 202: and judging whether the NR TBS is smaller than a TBS threshold value.

In this embodiment, after the NR TBS representing the transmission capability of the current 5G network is determined, the NR TBS needs to be compared with a TBS threshold as a standard to determine whether the transmission capability of the 5G network is good or bad.

In this embodiment, the method for acquiring the TBS threshold as the standard is not limited, and for example, the TBS corresponding to the transmission condition that is statistically obtained and can satisfy most users may be used as the TBS threshold.

Step 203: and if the NR TBS is smaller than the TBS threshold, closing the radio frequency system corresponding to the NR.

As described above, NR TBS characterizes the current 5G network transmission capability, with larger NR TBS indicating better current 5G network transmission capability and smaller NR TBS indicating worse current 5G network transmission capability. If the NR TBS is smaller than the TBS threshold, which indicates that the 5G transmission capability is poor, the radio frequency system corresponding to the NR is turned off, so that the power consumption of the UE can be reduced.

If the NR TBS is judged every time, the calculation pressure of the UE is increased undoubtedly; frequent switching of the rf system corresponding to NR also causes problems such as transmission seizure and damages to the rf system corresponding to NR. Based on this, in some specific embodiments,

the determination of the size NR TBS of the transport block corresponding to the new air interface is to determine NR TBSs corresponding to a plurality of downlink control messages DCI received within a preset time period;

correspondingly, if all NR TBSs determined within the preset time period are smaller than the TBS threshold, the radio frequency system corresponding to the NR is turned off.

The method comprises the steps that the NR TBSs corresponding to the DCIs received within the preset time period are determined, and all the NR TBSs determined within the preset time period are smaller than the TBS threshold, so that the radio frequency system corresponding to the NR is closed, and the problems of transmission blockage and the like caused by frequent switching on and off of the radio frequency system corresponding to the NR when the 5G network is unstable are avoided.

Fig. 4 is a schematic flowchart of another radio frequency system control method provided in an embodiment of the present invention, which is applied to the UE using NSA, and as shown in fig. 4, the method may include:

step 401: and if the radio frequency system corresponding to the new air interface NR of the UE is in an open state, determining the size NR TBS of the transmission block corresponding to the new air interface.

Step 402: and judging whether the NR TBS is smaller than a TBS threshold value.

Step 403: and if the NR TBS is smaller than the TBS threshold, closing the radio frequency system corresponding to the NR.

Steps 401 to 403 are the same as steps 201 to 203, and are not described herein again.

Step 404: and after waiting for a first time period, opening the radio frequency system corresponding to the NR, and re-executing the step of determining the NR TBS.

In this embodiment, after the radio frequency system corresponding to the NR is turned off, it cannot be known whether the current 5G transmission capability is good or bad, for example, after the 5G transmission capability is changed from bad, the 5G network cannot be connected in time when the 5G transmission capability is good because the current 5G transmission capability cannot be known in time.

Based on this, after the first duration needs to be waited for, the radio frequency system corresponding to the NR is turned on, and the 5G transmission capability is determined again.

According to the scheme, after the first time length is passed, the radio frequency system corresponding to the NR is turned on, and the step of determining the NRTBS is executed again, so that the 5G transmission capability can be known in time, and the problem that the 5G network cannot be connected in time after the 5G transmission capability is changed from poor to good is solved.

Fig. 5 is a schematic flowchart of another radio frequency system control method according to an embodiment of the present invention, which is applied to the UE using NSA, and as shown in fig. 5, the method may include:

step 501: and if the radio frequency system corresponding to the new air interface NR of the UE is in an open state, determining the size NR TBS of the transmission block corresponding to the new air interface.

Step 502: and judging whether the NR TBS is smaller than a TBS threshold value.

Step 503: and if the NR TBS is smaller than the TBS threshold, closing the radio frequency system corresponding to the NR.

The steps 501 to 503 are the same as the steps 201 to 203, and are not described herein again.

Step 504: and judging whether a data transmission instruction triggered by a user is received before a radio frequency system corresponding to the NR is opened.

Step 505: if so, taking a preset time length as the first time length.

In this embodiment, if a data transmission instruction triggered by a user is received, which indicates that the user is actively accessing the internet, at this time, more data may be sent, the radio frequency system corresponding to the NR needs to be turned on after waiting for a short time, and the 5G transmission capability needs to be determined again, so as to determine whether to connect to the 5G network more timely.

Based on the time length, a data transmission instruction triggered by a user is received, and the preset time length is directly used as the first time length.

Step 506: otherwise, determining a first adjustment amount corresponding to the continuous closing times; if the first adjustment amount is larger than a preset adjustment amount threshold value, taking the adjustment amount threshold value as a first target adjustment amount, and if the first adjustment amount is not larger than the adjustment amount threshold value, taking the first adjustment amount as the first target adjustment amount; and taking the sum of the preset time length and the first target adjustment amount as the first time length.

In this embodiment, if a data transmission instruction triggered by the user is not received, which indicates that the user is not actively accessing the internet, the first time duration of the radio frequency system interval corresponding to the NR from the turn-off to the turn-on may be determined according to the continuous turn-off times.

For example, if it is continuously determined that the NR TBS is smaller than the TBS threshold, i.e. the radio frequency system corresponding to NR is continuously turned off, which indicates that the 5G transmission capability is in a relatively poor state for a long time, it is not necessary to frequently determine whether the NR TBS is smaller than the TBS threshold, i.e. the first time duration may be set longer. For example:

the preset time length is 10s, the threshold value of the adjustment amount is 300s, the continuous closing times are 0, and the corresponding first adjustment amount is 0; the continuous closing frequency is 1, and the corresponding first adjustment amount is 0; the continuous closing times are 2, and the corresponding first adjustment amount is 10 s; the continuous closing times are 3, and the corresponding first adjustment amount is 30 s; the continuous closing times are 4, and the corresponding first adjustment amount is 70 s; the continuous closing frequency is 5, and the corresponding first adjustment amount is 150 s; the number of consecutive closings is 6, corresponding to a first adjustment amount of 310 s. When the continuous closing times are less than 6, the corresponding first adjustment amount is not greater than the adjustment amount threshold, so when the continuous closing times are less than 6, the corresponding first adjustment amount is taken as the first target adjustment amount. When the number of consecutive closings reaches 6, the corresponding first adjustment amount is larger than the adjustment amount threshold, so when the number of consecutive closings reaches 6, the adjustment amount threshold is set as the first target adjustment amount. The continuous closing times are 0, and the first time length is 10 s; the continuous closing times are 1, and the first time length is 10 s; the continuous closing times are 2, and the first time length is 20 s; the continuous closing times are 3, and the first time length is 40 s; the continuous closing times are 4, and the first time length is 80 s; the continuous closing times are 5, and the first time length is 160 s; the number of consecutive shutdowns reaches 6, and the first time period is 300 s.

The correspondence between the preset duration, the adjustment threshold, and the number of continuous closures and the first adjustment is merely an example, and the specific value or the specific correspondence may be set according to an actual application scenario.

In some specific embodiments, after the radio frequency system corresponding to the NR is turned off, the number of consecutive turning-off times is increased; and if the NR TBS is not smaller than the TBS threshold, setting the continuous closing times to be zero, thereby accurately obtaining the continuous closing times.

Step 507: and after waiting for a first time period, opening the radio frequency system corresponding to the NR, and re-executing the step of determining the NR TBS.

Step 507 is implemented in the same manner as step 204, and is not described herein again.

Fig. 6 is a schematic flowchart of another radio frequency system control method according to an embodiment of the present invention, which is applied to the UE using NSA, and as shown in fig. 6, the method may include:

step 601: and if the radio frequency system corresponding to the new air interface NR of the UE is in an open state, determining the size NR TBS of the transmission block corresponding to the new air interface.

Step 602: and judging whether the NR TBS is smaller than a TBS threshold value.

Step 603: and if the NR TBS is smaller than the TBS threshold, closing the radio frequency system corresponding to the NR.

Steps 601-603 are the same as steps 201-203, and are not described here.

Step 604: and if the NR TBS is not smaller than the TBS threshold, keeping the radio frequency system corresponding to the NR in an opening state.

Optionally, after step 604, the following steps are performed:

step 605: it is determined whether a user-triggered data transmission command is received before re-performing the step of determining the NR TBS.

Step 606: and if so, taking the preset time length as the second time length.

In this embodiment, if a data transmission instruction triggered by a user is received, it indicates that the user is actively accessing the internet, and the 5G transmission capability may change.

Based on the time length, a data transmission instruction triggered by a user is received, and the preset time length is directly used as a second time length.

By re-executing the step of determining the NR TBS while waiting for a short period of time when the user is actively accessing the internet, whether to change the 5G network connection state can be determined more timely.

Step 607: otherwise, determining a second adjustment amount corresponding to the continuous opening maintaining times; if the second adjustment amount is larger than a preset adjustment amount threshold, taking the adjustment amount threshold as a second target adjustment amount, and if the second adjustment amount is not larger than the adjustment amount threshold, taking the second adjustment amount as the second target adjustment amount; and taking the sum of the preset time length and the second target adjustment amount as the second time length.

In this embodiment, if a data transmission instruction triggered by the user is not received, which indicates that the user is not actively accessing the internet, the second duration of the NR TBS interval may be determined again according to the number of continuous on-times.

The specific embodiment of obtaining the second duration of the re-determined NR TBS interval according to the number of continuous turn-on times may refer to the implementation of determining the first duration of the radio frequency system interval corresponding to NR from turn-off to turn-on according to the number of continuous turn-off times, and details thereof are not repeated here.

If a data transmission instruction triggered by a user is not received, the second time length can be determined according to the continuous opening times, so that when the 5G transmission capacity is in a better state for a long time, whether the NR TBS is smaller than the TBS threshold value does not need to be frequently judged, and meanwhile, the adjustment threshold value is also set, and the problem that whether the 5G network needs to be disconnected cannot be timely determined due to the fact that the second time length is too long is avoided.

In some specific embodiments, after the radio frequency system corresponding to the NR is kept in the on state, the number of continuous on-holding times is increased; and if the NR TBS is smaller than the TBS threshold, setting the continuous keeping opening times to be zero, thereby accurately obtaining the continuous keeping opening times.

Step 608: and after waiting for the second time duration, re-executing the step of determining the NR TBS.

In this embodiment, the 5G transmission capability may change, for example, the NR TBS is affected by the change of the number of UEs in the cell and the change of the cell coverage, and when the 5G transmission capability becomes worse, the power consumption of the UE may increase if the 5G network is maintained. Based on this, it is necessary to wait for the second duration to elapse before re-determining the NR TBS.

As shown in fig. 7, based on the same inventive concept, an embodiment of the present invention provides a radio frequency system control apparatus 700, including: a TBS determining module 701, a determining module 702, and a radio frequency system control module 703.

A TBS determining module 701, configured to determine a transport block size NR TBS corresponding to a new air interface if a radio frequency system corresponding to the new air interface NR is in an on state;

a determining module 702, configured to determine whether the NR TBS is less than a TBS threshold;
