It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The network connection control method provided by the embodiment of the application can be applied to a dual connection architecture as shown in fig. 1. The terminal 101 may establish an air interface connection with the main base station 102 (also referred to as a master node), so as to implement communication with the main base station 102; the terminal 101 may also establish an air interface connection with the secondary base station 103 (also referred to as a secondary node), so as to implement communication with the secondary base station 103; the terminal 101 may also establish air interface connections with the main base station 102 and the secondary base station 103 at the same time, so as to simultaneously implement communication with the main base station 102 and the secondary base station 103.
In the dual connectivity mode, the terminal 101 establishes two connections with the primary base station 102 and the secondary base station 103 at the same time, where the primary base station 102 is mainly responsible for signaling transmission and the secondary base station 103 is mainly responsible for data transmission. The technical scheme of the embodiment of the application is mainly used for the terminal capable of supporting the dual-connection mode.
The types of the main base station 102 and the secondary base station 103 shown in fig. 1 may be the same or different. In one example, the primary base station 102 is an LTE base station and the secondary base station 103 is an NR base station. In another example, the primary base station 102 is an NR base station, and the secondary base station 103 is also an NR base station. In yet another example, the primary base station 102 is an NR base station and the secondary base station 103 is an LTE base station. The embodiment of the present application does not limit the types of the main base station 102 and the secondary base station 103.
In one example, the dual connection mode is an EN-DC mode or a next generation EN-DC (NGEN-DC) mode, in which case the primary base station is an LTE base station and the secondary base station is an NR base station, and the terminal communicates with both the LTE base station and the NR base station.
In another example, the dual connectivity mode is an NR-evolved UMTS (NR-EUTRA, NE-DC) mode, in which case the primary base station is an NR base station and the secondary base station is an LTE base station, and the terminal communicates with both the LTE and NR base stations.
It should be noted that the dual connection mode is not limited to the EN-DC mode and the NE-DC mode, and the specific type of the dual connection mode is not limited in the embodiment of the present application.
In a specific implementation, the deployment manner of the primary base station and the secondary base station may be co-base deployment (for example, the NR base station and the LTE base station may be disposed on one entity device), or may also be non-co-base deployment (for example, the NR base station and the LTE base station may be disposed on different entity devices), which is not limited in this application. Here, the LTE base station may be referred to as an evolved Node B (eNB), and the NR base station may be referred to as a next generation base station (gNB). It should be noted that the present application may not be limited to the correlation between the coverage areas of the primary base station and the secondary base station, for example, the primary base station and the secondary base station may overlap.
For a specific type of the terminal 101, the present application may not be limited, and it may be any user equipment that supports the above dual connection mode, for example, a smart phone, a personal computer, a notebook computer, a tablet computer, a portable wearable device, and the like.
The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. 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.
It should be noted that: in the present examples, "first", "second", etc. are used for distinguishing similar objects and are not necessarily used for describing a particular order or sequence.
The technical means described in the embodiments of the present application may be arbitrarily combined without 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 a first parameter;
here, the terminal is in a dual connectivity mode in which the terminal communicates with both the first base station and the second base station; the first base station is a main base station; the second base station is an auxiliary base station; the first parameter represents the error rate of an RLC layer when the terminal and the second base station carry out data transmission;
step 202: and under the condition that the first parameter meets a first preset condition, the terminal disconnects the communication connection between the terminal and the second base station.
Here, the first preset condition represents that the error rate of the RLC layer is greater than a preset threshold when the terminal performs data transmission with the second base station.
The preset threshold may be set as needed (for example, may be 20%), and when the first parameter is greater than the preset threshold, the terminal disconnects the communication connection between itself and the second base station if the first parameter is considered to meet a first preset condition; of course, when the first parameter is less than or equal to the preset threshold, the first parameter is considered not to satisfy the first preset condition.
In practical application, the first base station is a main base station; the secondary base station is responsible for transmitting data, the primary base station is mainly responsible for transmitting signaling (of course, it may also be responsible for transmitting signaling and transmitting partial data), and the terminal and the first base station and the second base station form a dual-connection architecture, referring to fig. 1.
In the 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 (i.e., a gNB), the second base station is an LTE base station (i.e., an eNB), and the terminal communicates with the NR base station and the LTE base station simultaneously. The terminal in the dual connection mode consumes more power than 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). Therefore, in the embodiment of the application, when the error rate of the RLC layer is greater than the preset threshold value when the terminal transmits data with the auxiliary base station, the terminal disconnects the terminal from the auxiliary base station, so that the power consumption of the terminal is saved, and the performance of the terminal is improved.
In practical applications, 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 and the first network are different networks.
Fig. 3 is a structural diagram of a communication module of a terminal in a dual connectivity mode, and as shown in fig. 3, in order to implement simultaneous communication with two base stations, the terminal needs to have two sets of communication modules, where the two sets of communication modules correspond to the two base stations respectively. The first modem 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. A second modem module (modem) and a second radio frequency path (including a second radio frequency circuit and a second radio frequency antenna) form a second set of communication modules, which correspond to a second base station. In one example, the first modem is a 5G modem, the second modem is a 4G modem, the first radio frequency circuitry is 5G RF, and the second radio frequency circuitry is 4G RF. In the dual connection mode, the first communication module and the second communication module operate simultaneously.
Specifically, in step 201, the terminal detects a first parameter, including:
the terminal detects a second parameter; the second parameter represents the retransmission condition of the uplink data packet on the RLC layer;
determining the first parameter based on the second parameter.
In practical application, the second parameter may be a parameter capable of characterizing a retransmission condition of any logical channel uplink data packet of the RLC layer, which is not limited in this embodiment of the present application. For example, the second parameter may include one of:
characterizing parameters of retransmission conditions of uplink data packets of a Broadcast Control CHannel (BCCH);
parameters characterizing retransmission conditions of Common Control CHannel (CCCH) uplink data packets;
characterizing parameters of retransmission conditions of uplink data packets of a Paging Control CHannel (PCCH);
characterizing parameters of retransmission conditions of uplink data packets of a Main Control CHannel (MCCH);
characterizing parameters of retransmission conditions of Multicast Traffic CHannel (MTCH) uplink data packets;
parameters characterizing retransmission conditions of Dedicated Control CHannel (DCCH) uplink data packets;
a parameter characterizing retransmission of Dedicated Transmission CHannel (DTCH) uplink data packets.
Correspondingly, the determining the first parameter based on the second parameter may include one of:
calculating based on the retransmission condition of the BCCH uplink data packet, and taking an obtained calculation result as a first parameter;
calculating based on the retransmission condition of the CCCH uplink data packet, and taking an obtained calculation result as a first parameter;
calculating based on the retransmission condition of the PCCH uplink data packet, and taking an obtained calculation result as a first parameter;
calculating based on the retransmission condition of the MCCH uplink data packet, and taking an obtained calculation result as a first parameter;
calculating based on the retransmission condition of the MTCH uplink data packet, and taking an obtained calculation result as a first parameter;
calculating based on the retransmission condition of the DCCH uplink data packet, and taking an obtained calculation result as a first parameter;
calculating based on the retransmission condition of the DTCH uplink data packet, and taking an obtained calculation result as a first parameter;
calculating based on retransmission conditions of uplink data packets of any two or more logic channels of the BCCH, the CCCH, the PCCH, the MCCH, the MTCH, the DCCH and the DTCH, and taking an obtained calculation result as a first parameter.
In practical application, the terminal selects one of the above modes to determine the first parameter according to needs. And selecting different modes to determine the first parameter, wherein the adopted preset threshold values are different.
In one embodiment, the calculating may include one of:
adding the bit error rates determined based on the retransmission conditions of the uplink data packets of the logic channels;
and weighting the determined error rate based on the retransmission condition of the uplink data packet of each logic channel. The weight value required by the weighting processing can be set according to requirements.
In practical application, the terminal may detect a PDU retransmission condition of a Protocol Data Unit (PDU) in an RLC layer in an Acknowledged Mode (AM) by using an Automatic Repeat reQuest (ARQ) technology, and obtain a detection result of the PDU retransmission condition shown in fig. 4, for example; and determining a first parameter based on the result of the detection.
In practical application, when the terminal disconnects the communication connection between itself and the second base station, it is 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 error rate of an RLC layer when the terminal and the first base station carry out data transmission;
correspondingly, in step 202, the terminal disconnects the communication connection between itself and the second base station when the first parameter meets a first preset condition and the third parameter meets a second preset condition.
Here, the second preset condition may be set according to needs, for example, a threshold may be set, where the second preset condition indicates that the error rate of the RLC layer is smaller than the set threshold when the terminal performs data transmission with the first base station. When the third parameter is smaller than a set threshold value, the third parameter is considered to meet a second preset condition; of course, when the third parameter is greater than or equal to the threshold, the third parameter is considered not to satisfy the second preset condition.
In practical application, after the terminal starts the communication function corresponding to the second base station, namely, after the terminal starts the function connected with the second base station, the terminal is in a dual-connection mode, and the terminal can be adjusted by combining practical conditions, so that the best compromise between performance and power consumption is achieved, and user experience is improved.
Based on this, in an embodiment, the terminal performs steps 201 to 202 under the condition that the function of connecting with the second base station is turned on.
Taking the communication function corresponding to the second base station as a 5G function as an example, referring to fig. 5, fig. 5 is a schematic diagram of turning on the intelligent 5G by the terminal, where turning on the intelligent 5G means optimizing the 5G function, and specifically, the terminal can prohibit using the 5G function in combination with an actual situation. As shown in fig. 5, the terminal turning on the smart 5G includes the following processes:
step 1: the terminal judges whether the operation of opening the intelligent 5G is received.
Here, the terminal displays a user interface including an option to start the smart 5G, and the user may trigger an operation to select the option corresponding to the smart 5G, thereby starting the smart 5G. Here, the operation by the user may be a touch operation, a key operation, a voice operation, a gesture operation, or the like.
Step 2: and if the operation of opening the intelligent 5G is received, optimizing the 5G function.
Here, the optimization of the 5G function includes at least: when the error rate of an RLC layer meets a first preset condition when the terminal transmits data with a second base station for realizing a 5G network, the terminal disconnects the communication connection between the terminal and the second base station; after the terminal disconnects the communication connection between the terminal and the second base station, the terminal is forbidden to be connected with the second base station for a period of time, namely, the 5G function is forbidden to be used, so that the power consumption of the terminal is reduced.
And step 3: and if the control instruction for opening the 5G function is not received, the 5G function is not optimized.
Specifically, in step 202, the disconnecting the communication connection between the terminal and the second base station includes:
sending first information to a network side device (specifically pointing to the second base station); the first information is used for the network side equipment 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 dual connectivity disconnection 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 that the connection between the terminal and the second base station fails.
In an example, taking the first network as a 5G network (which may also be referred to as an NR network) and the second network as a 4G network (which may also be referred to as an LTE network), the terminal is in the EN-DC mode, and a process of disconnecting the communication connection with the second base station is described.
As shown in fig. 6, the process of the terminal disconnecting the communication connection between itself and the second base station includes:
step 1: the terminal initiates (namely to a first base station) an NR SCG failure information flow at an LTE end;
here, the terminal sets the failureType field in the NR SCG failure information message to "t 310-exception", indicating that the connection between the terminal and the NR base station has failed.
The NR SCG failure information message does not include the measurement result for the NR base station.
Step 2: the network side equipment sends a secondary cell group releasing instruction to the terminal;
here, the release secondary cell group indication is used to instruct the terminal to release dual connectivity, that is, instruct the terminal to release connectivity with an NR base station.
The network side device may release a secondary cell group (release SCG) indication to the terminal through an RRC connection reconfiguration (RRC connection reconfiguration) message.
And step 3: and the terminal releases the double connection, namely releases the connection with the NR base station according to the secondary cell group releasing indication. Therefore, the terminal disconnects the communication connection between the terminal and the NR base station, namely, the NR base station is deactivated.
In practical application, after the terminal is disconnected from the second base station, the terminal can be prohibited from being connected with the second base station for a period of time, so that the power consumption of the terminal is reduced, the performance of the terminal is improved, the best compromise between the performance and the power consumption is achieved, and the user experience is improved.
Based on this, in an embodiment, after the communication connection with the second base station is disconnected, the method further includes: and the terminal forbids connection with the second base station.
In practical application, after the communication connection between the terminal and the second base station is prohibited for a period of time, the connection between the terminal and the second base station may be stopped, so that the transmission rate of data can be greatly increased.
Based on this, in an embodiment, the method may further include:
after connection with the second base station is forbidden, the terminal detects the connection forbidden time;
and when the connection prohibition time exceeds a preset time threshold, the terminal stops prohibiting connection with the second base station.
Here, the preset duration threshold may be set as needed.
Specifically, the prohibiting, by the terminal, connection with the second base station includes:
not responding to second information sent by the network side equipment; the second information is used for enabling the terminal to be connected 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 a measurement configuration reported by a network side device based on an event with number B1 from LTE to NR (LTE to NR B1 event), and the measurement request is used to instruct the terminal to measure the second base station.
The terminal determines a second base station measurement report transmission operation based on the second information; specifically, the terminal may not respond to the second information sent by the network side device by one of the following manners:
in the first mode, the terminal directly ignores the measurement request sent by the network side equipment;
in a second mode, the terminal ignores a measurement report for a measurement request; the measurement request is sent by the network side equipment; the measurement request is used for indicating the terminal to measure the second base station;
in a third mode, the terminal updates the first threshold from a first value to a second value; the first value is less than the second value; the first threshold is a reporting threshold of a measurement report of the second base station; 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 smaller than the second value, that is, the terminal suspends reporting the measurement report for the measurement request to the network side device.
In the first mode, after receiving the measurement request, the terminal does not perform measurement on the second base station according to the measurement request, for example, after receiving the measurement request, the terminal directly discards the measurement request, and the like. Here, since 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, and does not perform an operation of sending the measurement report for the second base station to the network side device.
In the second mode, after receiving the measurement request, the terminal may measure the second base station in response to the measurement request to obtain a measurement report for the second base station, but the terminal may 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. Here, although the terminal has measured the second base station based on the measurement request, the terminal does not perform an operation of transmitting a measurement report for the second base station to the network side device.
In a third mode, in practical application, the terminal may set the second value as a sum of the first value and a target value. Wherein the target value is a positive value. By updating the secondary base station measurement report reporting threshold to the sum of the first value and the target value, the probability that the terminal reports the measurement report for the second base station to the network side equipment 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 the measurement report reporting threshold of the second base station is updated, since 5 is greater than 4, the terminal may report the measurement report to the network side device; however, after the measurement report reporting threshold of the second base station is updated, since 5 is less than (4+2), the terminal cannot report the measurement report to the network side device.
Here, when actually applied, the target value may be set as needed. The larger the target value is, the smaller the probability that the terminal reports the measurement report of the second base station to the network side device is. When the target value is greater than or equal to a certain threshold, the probability that the terminal reports the measurement report of the second base station to the network side equipment is 0, that is, the terminal cannot report the measurement report of the auxiliary base station to the network side equipment. For example, assuming that the maximum value of the signal quality is 7, the reporting threshold of the measurement report of the first base station before updating is 4, and the target value is 4, after updating the reporting threshold, since 7 is smaller than (4+4), the signal quality in the measurement report of the auxiliary base station cannot be greater than 8, and therefore, even if the signal quality in the measurement report of the second base station is 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 connectivity disabling operation is implemented in a manner that the terminal does not report a measurement report for the second base station to the network side device, and since the network side device needs to configure the dual connectivity mode according to the measurement report for the second base station reported by the terminal, the network side device cannot configure the dual connectivity mode when the terminal does not send the measurement report for the second base station to the network side device, and 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) and the second network as a 4G network (which may also be referred to as an LTE network), the terminal is in an LTE mode (single connection mode), and a process in which the terminal prohibits the dual connection disable operation is described.
As shown in fig. 7, the process of the terminal prohibiting the dual connection disabling operation includes:
step 1: the terminal is in LTE mode;
step 2: the network side equipment issues a measurement configuration (NR measurement request) to the terminal;
here, the configuration measurement is reported based on the event threshold numbered B1.
And step 3: under the conditions that the error rate of an RLC layer is high when the terminal transmits data with an NR base station for realizing an NR network and the error rate of the RLC layer is low when the terminal transmits data with an LTE base station for realizing a 4G network, the NR measurement request configured for the network is not responded;
here, in actual application, after receiving the measurement request, the terminal may continue or suspend measurement of the NR base station, but does not report the measurement result for the NR base station, that is, step 4 is not performed.
Here, in actual application, when the terminal continues measurement of the NR base station, the measurement value of B1 on NR may be reduced.
Since the network side device does not receive the measurement result for the NR base station, the EN-DC may not be configured, and the terminal is still in the LTE mode, i.e., in the single connection mode.
Certainly, in actual application, when a communication function corresponding to the NR base station is needed (for example, the terminal needs to increase the data transmission rate, and the terminal determines that the connection prohibition duration exceeds the preset duration threshold, etc.), the terminal may restart reporting the measurement report for the NR base station to help the network side reconfigure the EN-DC.
In an example, taking the first network as a 5G network (which may also be referred to as an NR network) and the second network as a 4G network (which may also be referred to as an LTE network) as an example, the terminal disconnects the communication connection between itself and the second base station by using the method shown in fig. 6, that is, releases the dual connectivity. After releasing the dual connectivity, the terminal is in an LTE mode (single connectivity mode), the network side device may send a new measurement configuration for the NR base station to the terminal, and after receiving the new measurement configuration for the NR base station, the terminal does not respond to the new measurement configuration (e.g., does not report a measurement result for the NR base station), that is, the process shown in fig. 7 in which the terminal prohibits the dual connectivity disabling operation from being used is executed. After the communication connection between the terminal and the second base station is disconnected, the terminal is forbidden to be connected with the second base station for a period of time, so that the power consumption of the terminal is reduced, the performance of the terminal is improved, the best compromise between the performance and the power consumption is achieved, and the user experience is improved.
According to the control method, the terminal and the storage medium for network connection, the terminal detects a first parameter; the terminal is in a dual-connection mode, and in the dual-connection mode, the terminal is communicated with both the first base station and the second base station; the first base station is a main base station; the second base station is an auxiliary base station; the first parameter represents the error rate of an RLC layer when the terminal and the second base station carry out data transmission; and under the condition that the first parameter meets a first preset condition, the terminal disconnects the communication connection between the terminal and the second base station. Under the condition that the terminal is in double connection, when the error rate of an RLC layer accords with a preset condition when the terminal transmits data with an auxiliary base station, the terminal is disconnected from the auxiliary base station, the purposes of improving the performance of the terminal and reducing the power consumption of the terminal can be achieved, the endurance time of the terminal is prolonged, and the endurance capacity of the terminal is improved.
An embodiment of the present application further specifically provides a method for controlling network connection, including:
step 1: the terminal detects a first parameter; the first parameter represents the error rate of an RLC layer when the terminal and the second base station carry out data transmission;
here, the terminal is in a dual connectivity mode in which the terminal communicates with both the first base station and the second base station; the first base station is a main base station, and the second base station is an auxiliary base station.
Step 2: and judging whether the error rate is greater than a preset threshold value, and if the error rate is determined to exceed the preset threshold value, optimizing the terminal.
Here, the preset threshold may be set according to actual needs, for example, the first parameter is specifically an error rate of a DCCH uplink data packet, and the preset threshold is 20%; and when the error rate of the DCCH uplink data packet is more than 20%, optimizing by the terminal, otherwise, not optimizing.
Here, the optimizing may include: and (6) deactivating. The deactivation may be a method of the method shown in fig. 2, specifically, the method shown in fig. 6, in which the terminal disconnects the communication connection between itself and the second base station.
The optimization may further include: and forbidding the connection with the second base station for a period of time so as to reduce the power consumption of the terminal. Here, the second information sent by the network side device may not be responded to as described in the method shown in fig. 2, which is not described herein repeatedly.
