Wherein, the terminal 101 can establish an air interface connection with the primary base station 102 (also referred to as the primary node), thereby realizing communication with the primary base station 102; the terminal 101 can also establish an air interface connection with the secondary base station 103 (also referred to as the secondary node), Thereby, communication with the secondary base station 103 is realized; the terminal 101 can also establish an air interface connection with the primary base station 102 and the secondary base station 103 at the same time, thereby realizing communication with the primary base station 102 and the secondary base station 103 at the same time.

In the dual connection mode, the terminal 101 establishes two connections with the primary base station 102 and the secondary base station 103 at the same time, wherein the primary base station 102 is mainly responsible for transmitting signaling, and the secondary base station 103 is mainly responsible for transmitting data. The technical solutions of the embodiments of the present application are mainly aimed at a terminal capable of supporting a dual connection mode.

The types of the primary base station 102 and the secondary base station 103 shown in FIG. 1 may be the same or different. In an example, the primary base station 102 is an LTE base station, and the secondary base station 103 is an NR base station.

The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems will be specifically described in detail below with reference to the accompanying drawings. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

It should be noted that: in the examples of this application, "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

In addition, the technical solutions described in the embodiments of the present application may be combined arbitrarily unless there is a conflict.

An embodiment of the present application provides a method for controlling network connection. As shown in FIG. 2 , the method includes:

Step 201: the terminal detects the first parameter;

Here, the terminal is in a dual-connection mode, and in the dual-connection mode, the terminal communicates with both the first base station and the second base station; the first base station is the primary base station; the second base station is the secondary base station ; The first parameter represents the bit error rate of the RLC layer when the terminal and the second base station perform data transmission;

Step 202: In the case that the first parameter satisfies the first preset condition, the terminal disconnects the communication connection between itself and the second base station.

Here, the first preset condition indicates that the bit error rate of the RLC layer is greater than a preset threshold when the terminal and the second base station perform data transmission.

The preset threshold can be set as required (for example, it can be 20%), when the first parameter is greater than the preset threshold, it is considered that the first parameter satisfies the first preset condition, and the terminal is disconnected The communication connection between itself and the second base station; of course, when the first parameter is less than or equal to a preset threshold, it is considered that the first parameter does not meet the first preset condition.

In practical application, the first base station is the main base station; the secondary base station is responsible for transmitting data, the main base station is mainly responsible for transmitting signaling (of course, it can also be responsible for transmitting signaling and transmitting part of data), the terminal and the first base station are responsible for transmission. A dual-connection architecture is formed with the second base station, referring to FIG. 1 .

In this embodiment of the present application, the dual connection mode is, for example, an EN-DC mode, an NGEN-DC mode, or an NE-DC mode. Taking the EN-DC mode as an example, the first base station is an NR base station (ie gNB), the second base station is an LTE base station (ie eNB), and the terminal communicates with the NR base station and the LTE base station simultaneously. Compared with the terminal in the single connection mode (the terminal communicates with one base station (such as an LTE base station or an NR base station)), the terminal in the dual connection mode consumes more power. To this end, in the embodiment of the present application, when the bit error rate of the RLC layer is greater than a preset threshold when the terminal and the secondary base station perform data transmission, the terminal disconnects itself from the secondary base station, thereby saving the power consumption of the terminal, and further Improve terminal performance.

In practical application, the first base station and the second base station may be different types of base stations, that is, the second network where the first base station is located is a different network from the first network.

Figure 3 is a structural diagram of the communication module of the terminal in dual connection mode. As shown in Figure 3, in order to realize simultaneous communication with two base stations, the terminal needs to have two sets of communication modules, and the two sets of communication modules correspond to two base stations respectively. Wherein, the first modulation and demodulation module (modem) and the first radio frequency path (including the first radio frequency circuit and the first radio frequency antenna) form a first set of communication modules, and the first set of communication modules corresponds to the first base station. The second modulation and demodulation module (modem) and the second radio frequency path (including the second radio frequency circuit and the second radio frequency antenna) form a second set of communication modules, and the second set of communication modules corresponds to the second base station. In an example, the first modem is a 5G modem, the second modem is a 4G modem, the first radio frequency circuit is 5G RF, and the second radio frequency circuit is 4G RF. In the dual connection mode, the first communication module and the second communication module work simultaneously.

Specifically, in step 201, the terminal detects the first parameter, including:

The terminal detects a second parameter; the second parameter represents the retransmission situation of the uplink data packet at the RLC layer;

Based on the second parameter, the first parameter is determined.

In practical application, the second parameter may be a parameter capable of representing the retransmission situation of the uplink data packet of any logical channel of the RLC layer, which is not limited in this embodiment of the present application. For example, the second parameter may include one of the following:

A parameter that characterizes the retransmission situation of the broadcast control channel (Broadcast Control CHannel, BCCH) uplink data packet;

A parameter that characterizes the retransmission situation of the uplink data packet on the Common Control Channel (CCCH);

A parameter that characterizes the retransmission situation of the uplink data packet on the Paging Control Channel (PCCH);

A parameter that characterizes the retransmission situation of the main control channel (Main Control CHannel, MCCH) uplink data packet;

A parameter that characterizes the retransmission situation of the multicast traffic channel (Multicast Traffic CHannel, MTCH) uplink data packet;

A parameter that characterizes the retransmission situation of uplink data packets on a dedicated control channel (Dedicated Control CHannel, DCCH);

A parameter that characterizes the retransmission of uplink data packets on the Dedicated Transmission Channel (DTCH).

Correspondingly, the determining the first parameter based on the second parameter may include one of the following:

Calculate based on the retransmission situation of the BCCH uplink data packet, and use the obtained calculation result as the first parameter;

Calculate based on the retransmission situation of the CCCH uplink data packet, and use the obtained calculation result as the first parameter;

Calculate based on the retransmission situation of the PCCH uplink data packet, and use the obtained calculation result as the first parameter;

Calculate based on the retransmission situation of the MCCH uplink data packet, and use the obtained calculation result as the first parameter;

Calculate based on the retransmission situation of the MTCH uplink data packet, and use the obtained calculation result as the first parameter;

Calculate based on the retransmission situation of the DCCH uplink data packet, and use the obtained calculation result as the first parameter;

Calculate based on the retransmission situation of the DTCH uplink data packet, and use the obtained calculation result as the first parameter;

Based on the calculation based on the retransmission of uplink data packets of any two or more logical channels in the BCCH, the CCCH, the PCCH, the MCCH, the MTCH, the DCCH and the DTCH, we will get The result of calculation is used as the first parameter.

In practical application, the terminal selects one of the above manners to determine the first parameter as required. Different methods are selected to determine the first parameter, and different preset thresholds are used.

In one embodiment, the calculation may include one of the following:

Add the bit error rates determined based on the retransmission situation of the uplink data packets of each logical channel;

The bit error rate determined based on the retransmission of uplink data packets of each logical channel is weighted. The weights required for the weighting process can be set according to requirements.

In practical application, the terminal can use the automatic repeat request (Automatic Repeat reQuest, ARQ) technology to detect the retransmission situation of the protocol data unit (Protocol Data Unit, PDU) of the RLC layer in the Acknowledged Mode (Acknowledged Mode, AM), and obtain, for example, as shown in the figure. The detection result of the PDU retransmission situation shown in 4; and the first parameter is determined based on the detection result.

In practical application, when the terminal disconnects the communication connection between itself and the second base station, it is also necessary to ensure data transmission.

Based on this, in an embodiment, in step 201, when detecting the first parameter, the method may further include:

The terminal detects a third parameter; the third parameter represents the bit error rate of the RLC layer when the terminal and the first base station perform data transmission;

Correspondingly, in step 202, when the first parameter satisfies the first preset condition and the third parameter satisfies the second preset condition, the terminal disconnects itself from the second base station. communication connection between.

Here, the second preset condition may be set as required, for example, a threshold may be set, and the second preset condition indicates that the bit error rate of the RLC layer when the terminal and the first base station perform data transmission is less than the set threshold . When the third parameter is less than the set threshold, it is considered that the third parameter satisfies the second preset condition; of course, when the third parameter is greater than or equal to the threshold, it is considered that the third parameter does not meet the second preset condition Set conditions.

In practical application, after the terminal enables the communication function corresponding to the second base station, that is, after enabling the function of connecting with the second base station, the terminal is in dual-connection mode. The best compromise to improve user experience.

Based on this, in an embodiment, when the function of connecting with the second base station is enabled, the terminal executes steps 201-202.

Taking the communication function corresponding to the second base station as the 5G function as an example, referring to FIG. 5 , FIG. 5 is a schematic diagram of the terminal enabling smart 5G. Here, the meaning of enabling smart 5G refers to optimizing the 5G function. Specifically, the terminal can The use of 5G functions is prohibited according to the actual situation. As shown in Figure 5, enabling smart 5G on a terminal includes the following processes:

Step 1: The terminal determines whether an operation to turn on the smart 5G has been received.

Here, the terminal displays a user interface, and the user interface includes an option to enable smart 5G. The user can trigger an operation to select an option corresponding to smart 5G, thereby enabling smart 5G. Here, the user's operation may be a touch operation, a key operation, a voice operation, a gesture operation, or the like.

Step 2: If an operation to turn on smart 5G is received, optimize the 5G function.

Here, the optimization of the 5G function at least includes: when the bit error rate of the RLC layer satisfies the first preset condition when the terminal performs data transmission with the second base station implementing the 5G network, the terminal disconnects the communication between itself and the second base station. Communication connection: After the terminal disconnects the communication connection between itself and the second base station, it prohibits connection with the second base station for a period of time, that is, prohibits the use of the 5G function, so as to reduce the power consumption of the terminal.

Step 3: If the control command to enable the 5G function is not received, the 5G function will not be optimized.

Specifically, in step 202, the terminal disconnects the communication connection between itself and the second base station, including:

Send first information to the network side device (specifically to the second base station); the first information is used for the network side device to determine to disconnect the communication connection between the terminal and the second base station; In other words, the first information is used for the network-side device to determine the disconnected dual connection mode.

Specifically, the terminal sends a secondary cell group failure information message to the network side device; the secondary cell group failure information (SCG failure information) message carries first information, indicating the connection between the terminal and the second base station fail.

In an example, taking the first network as a 5G network (which may also be referred to as an NR network), the second network as a 4G network (which may also be referred to as an LTE network), and the terminal in EN-DC mode as an example, the description of the terminal disconnection is described as follows: The process of opening a communication connection with the second base station.

As shown in FIG. 6 , the process in which the terminal disconnects the communication connection between itself and the second base station includes:

Step 1: The terminal initiates (ie, to the first base station) the NR SCG failure information process at the LTE end;

Here, the terminal sets the failureType field in the NR SCG failure information message to "t310-Expiry", indicating that the connection between the terminal and the NR base station fails.

In the NR SCG failure information message, the measurement result for the NR base station is not included.

Step 2: the network side device sends an instruction to release the secondary cell group to the terminal;

Here, the indication of releasing the secondary cell group is used to instruct the terminal to release the dual connection, that is, instruct the terminal to release the connection with the NR base station.

Wherein, the network side device may realize the release of the secondary cell group (release SCG) indication to the terminal through an RRC connection reconfiguration (RRC connection reconfiguration) message.

Step 3: The terminal releases the dual connection according to the indication of releasing the secondary cell group, that is, releases the connection with the NR base station. Therefore, the terminal disconnects the communication connection between itself and the NR base station, that is, the NR base station is deactivated.

In practical applications, after the terminal disconnects the communication connection with the second base station, it can be prohibited from connecting with the second base station for a period of time, so as to reduce the power consumption of the terminal and improve the performance of the terminal, so as to achieve the best compromise between performance and power consumption. , to improve the user experience.

Based on this, in an embodiment, after disconnecting the communication connection with the second base station, the method further includes: prohibiting, by the terminal, connection with the second base station.

In practical applications, after prohibiting the communication connection between the terminal and the second base station for a period of time, the connection between the terminal and the second base station can be stopped, thereby greatly increasing the data transmission rate.

Based on this, in one embodiment, the method may further include:

After the connection with the second base station is prohibited, the terminal detects the connection prohibition duration;

When the connection prohibition duration exceeds a preset duration threshold, the terminal stops prohibiting connection with the second base station.

Here, the preset duration threshold may be set as required.

Specifically, prohibiting the terminal from connecting with the second base station includes:

Do not respond to the second information sent by the network side device; the second information is used to enable the terminal to connect with the second base station; in other words, the second information is used to enable the dual connection mode.

Here, the second information may be a measurement request for the second base station. For example, for the EN-DC mode, the measurement request may be an event numbered B1 based on LTE to NR configured by the network side device (LTE to NR B1 event), and the measurement request is used to instruct the terminal to measure the second base station.

The terminal determines the second base station measurement report sending operation based on the second information; specifically, the terminal may not respond to the second information sent by the network side device in one of the following ways:

In the first manner, the terminal directly ignores the measurement request sent by the network side device;

In the second manner, the terminal ignores the measurement report for the measurement request; the measurement request is sent by the network side device; the measurement request is used to instruct the terminal to measure the second base station;

In a third manner, the terminal updates a first threshold from a first value to a second value; the first value is smaller than the second value; the first threshold is based on the measurement report of the second base station reporting threshold; for the measurement request sent by the network-side device, the terminal ignores the measurement report for the measurement request when the measurement value is less than the second value, that is, the terminal suspends reporting the measurement for the measurement request to the network-side device Report.

Wherein, in the first manner, after receiving the measurement request, the terminal does not measure the second base station according to the measurement request. For example, after receiving the measurement request, the terminal directly The measurement request is discarded, etc. Here, because the terminal directly ignores the measurement request, the terminal does not measure the second base station according to the measurement request, and thus does not obtain a measurement report for the second base station. , the operation of sending the measurement report for the second base station to the network side device will not be performed.

In the second manner, after the terminal receives the measurement request, the terminal will measure the second base station in response to the measurement request, so as to obtain a measurement report for the second base station, but, The terminal will not send the measurement report for the second base station to the network side device, for example, the terminal discards the measurement report for the second base station and does not save the measurement report for the second base station Wait. Here, although the terminal measures the second base station based on the measurement request, the terminal does not perform an operation of sending a measurement report for the second base station to the network-side device.

In the third manner, in practical application, the terminal may set the second value as the sum of the first value and the target value. Wherein, the target value is a positive value. By updating the measurement report reporting threshold of the secondary base station to the sum of the first value and the target value, the probability of the terminal reporting the measurement report for the second base station to the network side device can be reduced. For example, assuming that in the measurement report for the second base station, the signal quality is 5, the first value is 4, and the target value is 2, before updating the measurement report reporting threshold of the second base station, since 5 is greater than 4, the terminal The measurement report can be reported to the network side device; however, after updating the measurement report reporting threshold of the second base station, since 5 is less than (4+2), the terminal cannot report the measurement report to the network side device.

Here, in practical application, when the target value can be set as required. The larger the target value, the smaller the probability of the terminal reporting the measurement report of the second base station to the network side device. When the target value is greater than or equal to a certain threshold, the probability of the terminal reporting the measurement report of the second base station to the network side device is 0, that is, the terminal cannot report the measurement report of the secondary base station to the network side device. For example, assuming that the maximum value of the signal quality is 7, the measurement report reporting threshold of the first base station before the update is 4, and the target value is 4, after the reporting threshold is updated, since 7 is less than (4+4), the measurement report of the secondary base station is The signal quality cannot be greater than 8, so even if the signal quality in the measurement report of the second base station is the maximum value of 7, the terminal cannot send the measurement report of the second base station to the network side device.

As can be seen from the above description, when the terminal is in the single-connection mode, the dual-connection disabling operation is implemented by the terminal not reporting the measurement report for the second base station to the network-side device , since the network-side device needs to configure the dual-connection mode according to the measurement report of the second base station reported by the terminal, the network-side device cannot configure the dual-connection mode if the terminal does not send the measurement report of the second base station to the network-side device mode, at this time, the terminal is still in the single connection mode.

In an example, taking the first network as a 5G network (which may also be referred to as an NR network), the second network as a 4G network (which may also be referred to as an LTE network), and the terminal being in an LTE mode (single connection mode) as an example, Describes the process by which the terminal prohibits the dual connection disable operation.

As shown in Figure 7, the process of the terminal prohibiting the use of dual-connection disabling operations includes:

Step 1: the terminal is in LTE mode;

Step 2: The network side device sends a measurement configuration (NR measurement request) to the terminal;

Here, the configuration measurement is reported based on the event threshold numbered B1.

Step 3: When the bit error rate of the RLC layer is high when the terminal and the NR base station implementing the NR network are performing data transmission and the bit error rate of the RLC layer is very low when the terminal and the LTE base station implementing the 4G network are performing data transmission, do not respond. NR measurement request for network configuration;

Here, in practical application, after receiving the measurement request, the terminal may continue or suspend the measurement of the NR base station, but not report the measurement result for the NR base station, that is, step 4 is not performed.

Here, in practical application, when the terminal continues the measurement of the NR base station, the measurement value of B1 on the NR can be reduced.

Since the network-side device has not received the measurement result for the NR base station, the EN-DC may not be configured, and the terminal is still in the LTE mode at this time, that is, in the single-connection mode.

Of course, in practical applications, when the communication function corresponding to the NR base station is required (for example, the terminal needs to increase the data transmission rate, the terminal determines that the connection prohibition duration exceeds the preset duration threshold, etc.), the terminal can restart and report the measurement report for the NR base station to help Reconfigure the EN-DC on the network side.

In an example, taking the first network as a 5G network (also referred to as an NR network) and the second network as a 4G network (also referred to as an LTE network), the method shown in FIG. 6 is used for the terminal to disconnect itself from the first network. The communication connection between the two base stations is to release the dual connection. After the dual connection is released, the terminal is in LTE mode (single connection mode), and the network side device may send a new measurement configuration for the NR base station to the terminal. After the terminal receives the new measurement configuration for the NR base station, Not responding to the new measurement configuration (for example, not reporting the measurement result for the NR base station), that is, executing the process of prohibiting the terminal from adopting the dual connection prohibition operation shown in FIG. 7 . After the above-mentioned terminal disconnects the communication connection with the second base station, the connection with the second base station is prohibited for a period of time, so as to reduce the power consumption of the terminal and improve the performance of the terminal, so as to achieve the best compromise between performance and power consumption, and improve the performance of the terminal. user experience.

In the network connection control method, terminal, and storage medium provided by the embodiments of the present application, the terminal detects a first parameter; the terminal is in a dual-connection mode, and in the dual-connection mode, the terminal communicates with the first base station and the second base station. The first base station is the primary base station; the second base station is the secondary base station; the first parameter represents the bit error rate of the RLC layer when the terminal and the second base station perform data transmission; When the first parameter satisfies the first preset condition, the terminal disconnects the communication connection between itself and the second base station. In the case where the terminal is in dual connection, when the bit error rate of the RLC layer meets the preset conditions when the terminal and the secondary base station perform data transmission, the terminal disconnects itself from the secondary base station, which can improve terminal performance and reduce terminal performance.
