Description

Working mode switching method, device, equipment and storage medium

Technical Field

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method, a device, equipment and a storage medium for switching working modes.

Background

The dual connectivity is one of the key technologies of the 5G new air interface network, and based on the dual connectivity technology, the user equipment is connected to two base stations simultaneously, one base station is called a Master Node (MN), and the other base station is called a Secondary Node (SN). And in a 5G network supporting dual connectivity technology, the base station side typically includes three modes of operation: the single link working mode is that only one wireless link of two wireless links is adopted between the base station side and the terminal side to transmit service data; the shunting working mode is that two wireless links are adopted between a base station side and a terminal side to respectively transmit different service data in a load sharing mode; and the repeated working mode is that two wireless links are adopted between the base station side and the terminal side to carry out repeated transmission on the same service data.

At present, when the reliability of data transmission needs to be improved, the current working mode of a base station is usually required to be automatically switched to a repeated working mode, and when the working mode is switched, a threshold value is usually set for each wireless link, measured values of a certain designated reliability parameter of a user terminal on two wireless links of a dual-connection system are respectively compared with a threshold value of the wireless link between a main node and the user terminal and a threshold value of the wireless link between an auxiliary node and the user terminal, and then the switching mode of the working mode of the base station is determined according to a comparison result.

However, in a manner of setting a threshold value in each wireless link, if the threshold value setting is conservative for any wireless link, the timeliness of the reliability improvement will not be good enough; if the threshold setting is aggressive, unnecessary radio resource consumption may result from unnecessary enablement of the copy operation mode. There is room for improvement in the existing manner of setting a threshold value for each radio link separately.

As shown in fig. 1, the method specifically includes the following operations:

step S101, a first measurement value of a specified reliability parameter of the user terminal on a first radio link and a second measurement value on a second radio link are measured.

Specifically, the present embodiment is applied to a dual connection system, where the dual connection system includes a user terminal, a primary base station connected to the user terminal by using a first wireless link, and a secondary base station connected to the user terminal by using a second wireless link. In order to reduce the cost, the embodiment of the application can adopt the intelligent lamp post as the base station, and particularly can adopt the intelligent lamp post as the main base station and the auxiliary base station; or the main base station is a macro base station, and the auxiliary base station is an intelligent lamp post. From the power supply and power grid matching aspect, the intelligent lamp post is provided with small-sized distribution box equipment, and the circuit of the equipment can directly supply power to the 5G micro base station, so that power grid equipment does not need to be additionally built, and most of construction cost is saved.

Optionally, measuring a first measurement value of a specified reliability parameter of the user terminal on the first wireless link and a second measurement value on the second wireless link includes: measuring a first measurement value of a first reliability parameter of the user terminal, which has no characteristic of being prone to faster fluctuations, on a first wireless link, and a second measurement value of the user terminal on a second wireless link, wherein the first reliability parameter comprises: a number of hybrid automatic repeat request negative acknowledgement (Hybrid Automatic Repeat request Not Acknowledge character, HARQ NACK) feedback or a number of retransmissions due to hybrid automatic repeat request HARQ, or a first measurement value on a first radio link of a second reliability parameter of the user terminal with a characteristic of being prone to faster fluctuations and a second measurement value on a second radio link, wherein the second reliability parameter comprises: downlink signal-to-interference-and-noise ratio (DownLink Signal to Interference plus Noise Ratio, DL SINR), which is typically characterized by a channel quality indication (Channel Quality Indication, CQI) fed back after the user terminal measures the channel state information reference signal CSI-RS.

Specifically, the specified reliability parameter in the present embodiment may be any given reliability parameter, and may be a first reliability parameter having a characteristic of being liable to fluctuate faster, or a second reliability parameter not having a characteristic of being liable to fluctuate faster. The specific types of the first reliability parameter and the second reliability parameter described above are merely examples, and the specific types of the first reliability parameter and the second reliability parameter are not limited in this embodiment. In addition, a first measurement value of the specified reliability parameter on the first radio link and a second measurement value on the second radio link are acquired during the measurement.

Step S102, determining the current working mode of the dual-connection system.

Optionally, determining the current operation mode of the dual connectivity system includes: when the first wireless link and the second wireless link respectively transmit different service data to the user terminal, determining that the current working mode of the dual-connection system is a shunting working mode; when only one of the first wireless link and the second wireless link transmits service data to the user terminal, the current working mode of the dual-connection system is determined to be a single-link working mode.

In this embodiment, the current operation mode is switched from the current operation mode to the copy operation mode, and when the current operation mode is determined to be the copy operation mode, the current operation mode is not switched. The current operation mode in this embodiment does not include the case of the copy operation mode.

Step S103, comparing the first measurement value with two thresholds of the first wireless link and comparing the second measurement value with two thresholds of the second wireless link based on the current operation mode, to determine whether the dual connectivity system needs to be switched to the copy operation mode.

Optionally, the threshold of the first wireless link includes a first threshold and a second threshold, and the first threshold is less than the second threshold; the threshold value of the second wireless link includes a third threshold value and a fourth threshold value, and the third threshold value is less than the fourth threshold value.

Specifically, a first threshold on the first wireless link may be represented by R1, a second threshold may be represented by R2, a third threshold on the second wireless link may be represented by R3, a fourth threshold may be represented by R4, and R1 is less than R2 and R3 is less than R4. Thus, two thresholds are set on each wireless link, respectively, and a smaller threshold is set on each link, i.e., R1 and R3 are used to establish a baseline for the reliability requirements that are expected to be achieved; and the larger value threshold value set on each link, namely R2 and R4, is used for creating a reliability allowance for timely enabling the copy operation mode.

Optionally, comparing the first measurement value with two thresholds of the first wireless link and comparing the second measurement value with two thresholds of the second wireless link based on the current operation mode to determine whether the dual connectivity system needs to be switched to the copy operation mode, including: when the current working mode is a shunt working mode and the specified reliability parameter is a first reliability parameter, comparing the first measured value with two thresholds of the first wireless link and comparing the second measured value with two thresholds of the second wireless link to determine whether the dual-connection system is required to be switched from the shunt working mode to the replication working mode; when the current working mode is a shunting working mode and the designated reliability parameter is a second reliability parameter, comparing the first measured value with two thresholds of the first wireless link, comparing the second measured value with two thresholds of the second wireless link, and determining whether the dual-connection system is required to be switched from the shunting working mode to the copying working mode according to the comparison result and whether the dual-connection system can be kept unchanged within the designated time range.

Optionally, comparing the first measurement value with two thresholds of the first wireless link and comparing the second measurement value with two thresholds of the second wireless link based on the current operation mode to determine whether the dual connectivity system needs to be switched to the copy operation mode, including: when the current working mode is a single-link working mode and the specified reliability parameter is a first reliability parameter, comparing the first measured value with two thresholds of the first wireless link and comparing the second measured value with two thresholds of the second wireless link to determine whether the double-connection system is required to be switched from the single-link working mode to the duplication working mode; when the current working mode is a single-link working mode and the designated reliability parameter is a second reliability parameter, comparing the first measured value with two thresholds of the first wireless link, comparing the second measured value with two thresholds of the second wireless link, and determining whether the double-connection system is required to be switched from the single-link working mode to the copy working mode according to the comparison result and whether the comparison result can be kept unchanged within the designated time range.

In this embodiment, when the current working mode is the shunt working mode, trigger switching of the copy working mode is performed by adopting different schemes according to whether the specified reliability parameter has the characteristic of easy and rapid fluctuation; when the current working mode is a single-link working mode, trigger switching of the copying working mode is performed by adopting different schemes according to the characteristic that whether the designated reliability parameter has fluctuation easily and quickly or not. And by comparing the measured value of the specified reliability parameter measured on each wireless link with two thresholds on the wireless link, when the comparison result accords with the copy operation mode switching condition, the switching of the copy operation mode is triggered, and when the comparison result does not accord with the copy operation mode switching condition, other reasonable processing is also performed.

Example two

Fig. 2 is a flowchart of an operation mode switching method according to an embodiment of the present invention, and based on the foregoing embodiment, step S103 is specifically described, where the method steps specifically include the following operations:

in step S201, when the current operation mode is the split operation mode and the specified reliability parameter is the first reliability parameter, the first measurement value is compared with two thresholds of the first wireless link, and the second measurement value is compared with two thresholds of the second wireless link, so as to determine whether the dual connectivity system needs to be switched from the split operation mode to the copy operation mode.

Optionally, comparing the first measurement value with two thresholds of the first wireless link and comparing the second measurement value with two thresholds of the second wireless link to determine whether the dual connectivity system needs to be switched from the split operation mode to the copy operation mode includes: when the first measured value of the user terminal on the first wireless link is between the first threshold value and the second threshold value, and the second measured value of the user terminal on the second wireless link is larger than the fourth threshold value, switching the dual-connection system from the shunting working mode to the copying working mode; when the first measured value of the user terminal on the first wireless link is larger than the second threshold value and the second measured value of the user terminal on the second wireless link is between the third threshold value and the fourth threshold value, switching the dual-connection system from the shunting working mode to the copying working mode; when the first measurement value of the user terminal on the first wireless link is between the first threshold value and the second threshold value, and the second measurement value of the user terminal on the second wireless link is between the third threshold value and the fourth threshold value, and the ongoing service on the user terminal is aggressive in the performance requirement of reliability, the dual connectivity system is switched from the split operation mode to the duplication operation mode.

Optionally, the method further comprises: when the current working mode is a shunting working mode, if the first measured value of the user terminal on the first wireless link is larger than a second threshold value and the second measured value of the user terminal on the second wireless link is larger than a fourth threshold value, the dual-connection system is kept in the current shunting working mode; when the current operation mode is a split operation mode, a first measured value of the user terminal on the first wireless link is between a first threshold value and a second threshold value, a second measured value of the user terminal on the second wireless link is between a third threshold value and a fourth threshold value, and the ongoing service on the user terminal is not aggressive in performance requirements of reliability, switching the dual-connection system from the split operation mode to a single-link operation mode, wherein the wireless link selected as the single-service link has a relatively high short-term average value of the measured values of the specified reliability parameters; when the current working mode is a split-flow working mode, a first measured value of the user terminal on a first wireless link is smaller than a first threshold value, and a second measured value of the user terminal on a second wireless link is larger than a third threshold value, switching the dual-connection system from the split-flow working mode to a single-link working mode, wherein the wireless link selected as a single-service link is a second wireless link; when the current working mode is a split-flow working mode, a first measured value of the user terminal on a first wireless link is larger than a first threshold value, and a second measured value of the user terminal on a second wireless link is smaller than a third threshold value, switching the dual-connection system from the split-flow working mode to a single-link working mode, wherein the wireless link selected as a single-service link is the first wireless link; when the current operation mode is a split operation mode, a first measurement value of the user terminal on a first radio link is smaller than a first threshold value, and a second measurement value of the user terminal on a second radio link is smaller than a third threshold value, the dual connectivity system is switched from the split operation mode to a single-link operation mode, while a software feature for enhancing reliability and which is not normally activated is activated for the user terminal, wherein the radio link selected as a single service link has a relatively high short-term average value of the measurement values of the specified reliability parameters.

Specifically, as shown in fig. 3, in the present embodiment, when the specified reliability parameter does not have a characteristic that is liable to fluctuate faster, the switching from the shunt operation mode to the copy operation mode is schematically performed. As can be seen from fig. 3, when the current operation mode is determined to be the split operation mode, the main base station in the dual-connection system can learn the measured values of the specified reliability parameters on the two wireless links according to the feedback of the user terminal. The first threshold on the first wireless link may be represented by R1, the second threshold may be represented by R2, the third threshold on the second wireless link may be represented by R3, the fourth threshold may be represented by R4, and R1 is less than R2 and R3 is less than R4. And according to the different relations between the measured value of the specified reliability parameter and the threshold value, the following situations are determined:

first case: if the first measured value RA on the first radio link is greater than R2 and the second measured value RB on the second radio link is greater than R4, the master base station keeps the current operation mode of the user terminal UE, i.e. the split operation mode, unchanged.

Second case: if the first measurement RA on the first radio link is between R1 and R2 and the second measurement RB on the second radio link is greater than R4; alternatively, if the reliability parameter RB on the second radio link is located between R3 and R4 and the second measured value RB on the first radio link is greater than R2, the master base station causes the UE to switch the operation mode to the copy operation mode. In other words, as long as the measured value of the specified reliability parameter on any one of the two wireless links is located between two thresholds of the two wireless links, and meanwhile, the measured value of the specified reliability parameter on the other wireless link is larger than the threshold with a higher numerical value on the wireless link, the master base station enables the UE to switch the working mode into the copy working mode.

Third case: if the first measurement value RA on the first radio link is located between R1 and R2, and the second measurement value RB on the second radio link is located between R3 and R4, further determining whether the ongoing service is more aggressive in terms of performance requirements of reliability, and if so, the master base station causing the UE to switch the operation mode to the copy operation mode; if the determination is not aggressive, the short-term averages of the reliability parameter measurements over the two wireless links are compared to determine which wireless link has a relatively higher short-term average, the master base station causes the UE to switch operating mode to single-link operating mode, and the link selected as the single-service link has a relatively higher short-term average.

Fourth case: if the first measured value RA on the first wireless link is smaller than R1 and the second measured value RB on the second wireless link is larger than R3, the main base station can enable the UE to switch the working mode into a single-link working mode, and the second wireless link is selected as a single-service link; or if the first measured value RA on the first radio link is greater than R1 and the second measured value RB on the second radio link is less than R3, the master base station may cause the UE to switch the operation mode to the single-link operation mode, and the single-service link is selected as the first radio link.

Fifth case: if the first measured value RA on the first radio link is smaller than R1 and the second measured value RB on the second radio link is smaller than R3, the master base station may perform special handling on the UE, e.g. when changing the operation mode to a single link operation mode, a software feature for enhancing reliability is activated for the UE and is not activated in the normal case, wherein the radio link selected as single service link has a relatively high short term average of the measured values of the specified reliability parameters.

Step S202, when the current operation mode is the split operation mode and the specified reliability parameter is the second reliability parameter, comparing the first measurement value with two thresholds of the first wireless link, and comparing the second measurement value with two thresholds of the second wireless link, and determining whether the dual connection system needs to be switched from the split operation mode to the copy operation mode according to the comparison result and whether the dual connection system can be kept unchanged within the specified time range.

As shown in fig. 4, in the present embodiment, when the reliability parameter has the characteristic of easily and quickly generating the fluctuation, as can be seen from fig. 4, the switching from the shunt operation mode to the replication operation mode is shown, and in comparison with fig. 3, when the reliability parameter has the characteristic of easily and quickly generating the fluctuation, the comparison result stability is limited, and in particular, there are several cases in which:

First case: within a given first time range, if the first measurement RA on the first radio link is always between R1 and R2 and the second measurement RB on the second radio link is always greater than R4; alternatively, in a given first time range, the master base station causes the UE to switch the operation mode to the copy operation mode if the second measured value RB on the second radio link is always between R3 and R4 and the first measured value RB on the first radio link is always greater than R2. In other words, as long as the measured value of the specified reliability parameter on any one of the two wireless links is relatively stably located between two thresholds of the wireless link, and meanwhile, the measured value of the specified reliability parameter on the other wireless link is relatively stably larger than the threshold of the higher value on the wireless link, the master base station enables the UE to switch the working mode into the copy working mode.

Second case: if the first measured value RA on the first radio link is always before R1 and R2 and the second measured value RB on the second radio link is always between R3 and R4 within the given second specified time range, it is further determined whether the ongoing traffic is aggressive in terms of performance requirements of reliability, and if it is determined that the aggressive is aggressive, the master base station causes the UE to switch the operation mode to the copy operation mode; if the determination is not aggressive, the short-term averages of the reliability parameter measurements over the two wireless links are compared to determine which wireless link has a relatively higher short-term average, the master base station causes the UE to switch operating mode to single-link operating mode, and the link selected as the single-service link has a relatively higher short-term average.

Third case: in a given third specified time range, if the first measured value RA on the first radio link is always smaller than R1 and the second measured value RB on the second radio link is always larger than R3, the master base station will cause the UE to switch the operation mode to the single-link operation mode, and the single-service link is selected as the second radio link; alternatively, if the first measurement value RA on the first radio link is always greater than R1 and the second measurement value RB on the second radio link is always less than R3 within the given third specified time range, the master base station may cause the UE to switch the operation mode to the single-link operation mode, and the single-service link is selected as the first radio link.

Fourth case: in a given fourth specified time range, if the first measured value RA on the first radio link is always smaller than R1 and the second measured value RB on the second radio link is always smaller than R3, the master base station will perform special handling on the UE, e.g. when changing the operation mode to a single link operation mode, a software feature for enhancing reliability is activated for the UE and is not activated in the normal case, wherein the radio link selected as single service link has a relatively high short term average of the measured values of the specified reliability parameters.

Example III

Fig. 5 is a flowchart of an operation mode switching method according to an embodiment of the present invention, and based on the above embodiment, step S103 is specifically described, where the method steps specifically include the following operations:

in step S301, when the current operation mode is the single link operation mode and the specified reliability parameter is the first reliability parameter, the first measurement value is compared with two thresholds of the first wireless link, and the second measurement value is compared with two thresholds of the second wireless link, so as to determine whether the dual connectivity system needs to be switched from the single link operation mode to the copy operation mode.

Optionally, comparing the first measurement with two thresholds of the first wireless link and comparing the second measurement with two thresholds of the second wireless link to determine whether the dual connectivity system needs to be switched from the single link mode of operation to the duplicate mode of operation includes: when the base station side is determined to transmit service data to the user terminal by adopting the first wireless link only, and the first measured value of the user terminal on the first wireless link is not greater than a second threshold value, the main base station requires the user terminal to measure on a second wireless link and report the second measured value;

When the base station side only adopts the first wireless link to transmit service data to the user terminal, and the first measured value of the user terminal on the first wireless link is positioned between the first threshold value and the second threshold value, and the second measured value of the user terminal on the second wireless link is larger than the fourth threshold value, switching the double-connection system from a single-link working mode to a duplication working mode;

and when the base station side only adopts the first wireless link to transmit service data to the user terminal, the first measured value of the user terminal on the first wireless link is positioned between the first threshold value and the second threshold value, the second measured value of the user terminal on the second wireless link is positioned between the third threshold value and the fourth threshold value, and the ongoing service on the user terminal is aggressive in the performance requirement of reliability, switching the dual-connection system from the single-link working mode to the duplication working mode.

Optionally, the method further comprises: when the base station side only adopts the first wireless link to transmit service data to the user terminal and the first measured value of the user terminal on the first wireless link is larger than a second threshold value, the dual-connection system is kept in a current single-link working mode and a current single-service link is kept to be used; when it is determined that the base station side transmits service data to the user terminal using only the first wireless link, and that the first measurement value of the user terminal on the first wireless link is between the first threshold value and the second threshold value, the second measurement value of the user terminal on the second wireless link is between the third threshold value and the fourth threshold value, and that the ongoing service on the user terminal is not aggressive in performance requirements of reliability, maintaining the dual connection system in a current single-link operation mode, wherein the wireless link selected as the single-service link has a relatively high short-term average value of the measurement values of the specified reliability parameters; when the base station side is determined to transmit service data to the user terminal by adopting the first wireless link only, and the first measured value of the user terminal on the first wireless link is between the first threshold value and the second threshold value, and the second measured value of the user terminal on the second wireless link is smaller than the third threshold value, the dual-connection system is kept in the current single-link working mode, and the current single-service link is kept in use; when the base station side is determined to transmit service data to the user terminal by adopting the first wireless link only, the first measured value of the user terminal on the first wireless link is smaller than a first threshold value, and the second measured value of the user terminal on the second wireless link is larger than a third threshold value, the dual-connection system is kept in a current single-link working mode, and the transmission of the service data to the user terminal by adopting the second wireless link is adjusted; when it is determined that the base station transmits service data to the user terminal using only the first radio link, and that the first measurement value of the user terminal on the first radio link is smaller than a first threshold value and the second measurement value of the user terminal on the second radio link is smaller than a third threshold value, the dual connectivity system is maintained in a current single-link operation mode, and if the second radio link has a relatively high short-term average value of the measurement values of the specified reliability parameters, the second radio link is adapted to be a single service link, while a software feature for enhancing the reliability and which is not activated in the conventional case is activated for the user terminal.

As shown in fig. 6, when the reliability parameter does not have the characteristic of easily and quickly generating fluctuation, as can be seen from fig. 6, when the current operation mode is determined to be the single-link operation mode and the single-service link of the current UE is the first wireless link, the master base station in the dual-connection system can obtain the first measurement value on the first wireless link currently used according to the feedback of the UE. And according to the different relations between the measured value of the specified reliability parameter and the threshold value, the following situations are determined:

first case: if the first measured value RA on the first radio link is larger than R2, the master base station keeps the user terminal UE in the current operation mode, i.e. single link operation mode, and keeps the current single service link in use.

Second case: if the first measurement RA on the first radio link is located between R1 and R2 and the measurement of the second measurement RB on the second radio link is greater than R4, the master base station causes the UE to switch the operating mode to a copy operating mode.

Third case: if the first measured value RA on the first wireless link is located between R1 and R2, and the second measured value RB on the second wireless link is located between R3 and R4, further judging whether the ongoing service is more aggressive in the performance requirement of reliability, if so, the main base station can enable the UE to switch the working mode to the copy working mode; if the determination is not aggressive, the short-term averages of the reliability parameter measurements over the two wireless links are compared to determine which wireless link has a relatively higher short-term average, the primary base station will leave the UE in single-link mode of operation, and the link selected as the single-service link has a relatively higher short-term average of the measurements of the specified reliability parameter.

Fourth case: if the first measurement RA on the first radio link is between R1 and R2 and the second measurement RB on the second radio link is less than R3, the master base station will let the UE maintain the current single-link operation mode and keep using the current single-service link.

Fifth case: if the first measurement RA on the first radio link is less than R1 and the second measurement RB on the second radio link is greater than R3, the master base station will let the UE maintain the current single link operation mode, but will change the single service link to another radio link, i.e. the second radio link.

Sixth case: if the first measurement RA on the first radio link is less than R1 and the second measurement RB on the second radio link is less than R3, the dual connectivity system is maintained in the current single link mode of operation, and if the second radio link has a relatively high short term average of measurements of specified reliability parameters, the second radio link is adapted to be the single service link and the master base station will perform special handling of the UE, e.g. activate a software feature for the UE that enhances reliability and that will not be activated in the normal case.

Step S302, when the current working mode is a single-link working mode and the designated reliability parameter is a second reliability parameter, comparing the first measured value with two thresholds of the first wireless link and comparing the second measured value with two thresholds of the second wireless link, and determining whether the dual-connection system is required to be switched from the single-link working mode to the duplication working mode according to the comparison result and whether the dual-connection system can be kept unchanged within the designated time range.

As shown in fig. 7, in order to switch from the single-link operation mode to the copy operation mode when the specified reliability parameter has the characteristic of easily and quickly fluctuating, as can be seen from fig. 7, in comparison with fig. 6, the measured value of the specified reliability parameter is compared with the threshold value, and there are several specific cases in which the stability of the comparison result is increased:

first case: in a given fifth time range, the master base station causes the UE to switch the operation mode to the copy operation mode if the first measurement RA on the first radio link is always between R1 and R2 and the second measurement RB on the second radio link is always greater than R4.

Second case: in a given fifth time range, if the first measured value RA on the first radio link is always located between R1 and R2, and the second measured value RB on the second radio link is always located between R3 and R4, it is further determined whether the ongoing traffic is more aggressive in terms of performance requirements of reliability, and if it is determined that the comparison is aggressive, the master base station causes the UE to switch the operation mode to the copy operation mode; if the determination is not aggressive, the short-term averages of the reliability parameter measurements over the two wireless links are compared to determine which wireless link has a relatively higher short-term average, the primary base station will leave the UE in single-link mode of operation, and the link selected as the single-service link has a relatively higher short-term average.

Third case: in the given fifth time range, if the first measurement value RA on the first radio link is always between R1 and R2 and the second measurement value RB on the second radio link is always smaller than R3, the master base station will let the UE keep the current single-link operation mode and keep using the current single-service link.

Fourth case: in the given sixth time range, if the first measurement RA on the first radio link is always smaller than R1 and the second measurement RB on the second radio link is always larger than R3, the master base station will let the UE maintain the current single-link operation mode, but will change the single-service link to another radio link, i.e. the second radio link.

Fifth case: in a given sixth time range, if the first measurement RA on the first radio link is always smaller than R1 and the second measurement RB on the second radio link is always smaller than R3, the dual connectivity system is kept in the current single link mode of operation, and if the second radio link has a relatively high short term average of measurements of specified reliability parameters, the second radio link is adapted to be the single service link while the master base station shall handle the UE specifically, e.g. activate a software feature for the UE that enhances reliability and that will not be activated in the normal case.

Optionally, comparing the first measurement with two thresholds of the first wireless link and comparing the second measurement with two thresholds of the second wireless link to determine whether the dual connectivity system needs to be switched from the single link mode of operation to the duplicate mode of operation includes: when the base station side is determined to transmit service data to the user terminal by adopting the second wireless link only, and the second measured value of the user terminal on the second wireless link is not greater than a fourth threshold value, the main base station requests the user terminal to measure on the first wireless link and report the first measured value; when the base station side only adopts the second wireless link to transmit service data to the user terminal, and the second measured value of the user terminal on the second wireless link is positioned between the third threshold value and the fourth threshold value, and the first measured value of the user terminal on the first wireless link is larger than the second threshold value, switching the double-connection system from a single-link working mode to a duplication working mode; and when the base station side only adopts the second wireless link to transmit service data to the user terminal, and the second measured value of the user terminal on the second wireless link is positioned between the third threshold value and the fourth threshold value, the first measured value of the user terminal on the first wireless link is positioned between the first threshold value and the second threshold value, and the ongoing service on the user terminal is aggressive in the performance requirement of reliability, switching the dual-connection system from the single-link working mode to the duplication working mode.

Optionally, the method further comprises: when the base station side only adopts the second wireless link to transmit service data to the user terminal and the second measured value of the user terminal on the second wireless link is larger than a fourth threshold value, the dual-connection system is kept in a current single-link working mode and a current single-service link is kept to be used; when it is determined that the base station side transmits service data to the user terminal using only the second radio link, and that the second measurement value of the user terminal on the second radio link is between the third threshold value and the fourth threshold value, the first measurement value of the user terminal on the first radio link is between the first threshold value and the second threshold value, and that the ongoing service on the user terminal is not aggressive in performance requirements of reliability, maintaining the dual-connection system in a current single-link operation mode, wherein the radio link selected as the single-service link has a relatively high short-term average value of the measurement values of the specified reliability parameters; when the base station side is determined to transmit service data to the user terminal by adopting the second wireless link only, and the second measured value of the user terminal on the second wireless link is between the third threshold value and the fourth threshold value, the first measured value of the user terminal on the first wireless link is smaller than the first threshold value, the dual-connection system is kept in the current single-link working mode, and the current single-service link is kept in use; when the base station side is determined to transmit service data to the user terminal by adopting the second wireless link only, the second measured value of the user terminal on the second wireless link is smaller than a third threshold value, and the first measured value of the user terminal on the first wireless link is larger than a first threshold value, the dual-connection system is kept in a current single-link working mode, and the transmission of the service data to the user terminal by adopting the first wireless link is adjusted; when it is determined that the base station transmits service data to the user terminal using only the second radio link, and that the second measurement value of the user terminal on the second radio link is smaller than the third threshold value, and that the first measurement value of the user terminal on the first radio link is smaller than the first threshold value, the dual connectivity system is maintained in the current single-link operation mode, and if the first radio link has a relatively high short-term average value of the measurement values of the specified reliability parameters, the first radio link is adapted to be the single service link, while a software feature for enhancing the reliability and which would not be activated in the conventional case is activated for the user terminal.
