The following will specifically describe the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by means of examples and with reference to the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
An embodiment of the present application provides a network connection method, which may be applied to the terminal 101 shown in fig. 1, please refer to an optional flowchart of the network connection method shown in fig. 3, and the method includes the following steps:
step 310, acquiring a screen state of a terminal; the screen state characterizes the use of the screen of the terminal.
The terminal mentioned in the embodiment of the present application may support a dual-connection mode, in which the terminal is simultaneously connected to a first communication network and a second communication network; it will be appreciated that the terminal communicates with both the first network device (i.e. the network device in the first communication network) and the second network device (i.e. the network device in the second communication network).
In one possible implementation, the first communication network is a secondary network and the second communication network is a primary network. Specifically, the secondary network is used for transmitting data, and the primary network is mainly used for transmitting signaling.
In this embodiment of the present application, the first communication network and the second communication network may be different types of networks, or may be the same type of network. In an alternative embodiment of the present application, the first communication network is an NR network (i.e. a 5G network) and the second communication network is an LTE network (i.e. a 4G network). It should be noted that, in the embodiment of the present application, the type of the second communication network is not limited.
In the embodiment of the application, a screen for displaying information is included on the physical structure of the terminal; specifically, the terminal can acquire the screen state thereof in real time; in one possible example, the terminal may obtain and identify the screen state through system application layer code logic.
In the embodiment of the application, the screen state represents the screen use condition of the terminal.
In general, the screen states may include a bright screen state and an off screen state. In a bright screen state, a display panel of a screen of the terminal is lightened, and a current application program interface is displayed; in the off-screen state, the display panel of the terminal screen is turned off, and no image is displayed.
In practical application, when the terminal screen is in a bright screen state, relevant information of a user concerned with the terminal is indicated; when the terminal screen is in the off-screen state, the user is not concerned with the relevant information of the terminal.
Step 320, if the screen state is the off-screen state, sending first indication information to the network device, where the first indication information is used to indicate that the first signal quality of the first communication network is less than a first threshold.
Here, the first threshold is used for judging the quality of the first signal, and when the first signal quality is smaller than the first threshold, it is indicated that the current first signal quality is poor, and the network of the terminal needs to be reconfigured.
Based on the description in step 310, the terminal screen is in an off-screen state, indicating that the user is not paying attention to the relevant information of the terminal. Therefore, the terminal can send the first indication information to the network equipment under the condition that the screen is in the off-screen state, and inform the network equipment that the signal quality of the current first communication network is relatively poor, so that the network equipment is guided to reconfigure the network, the terminal is disconnected with the first communication network, the first communication network is deactivated, the connection of one communication network is reduced, and the purpose of reducing the power consumption of the terminal is achieved.
It should be noted that, the first indication information may be any type of uplink data; for example, the first indication information may be a reconfiguration response message, or may be a measurement report of any kind of measurement event; the embodiment of the present application does not limit the type of the first indication information here.
In the embodiment of the present application, the first indication information may, but is not limited to, indicate that the first signal quality of the first communication network is less than the first threshold by any one of the following manners:
1. the terminal indicates whether the first signal quality is smaller than a first threshold value by setting different values for a certain identification bit in the first indication information.
In a possible example, the terminal may set a value of an identification bit in the first indication information to 0, which indicates that the first network signal quality is greater than or equal to the first threshold; or, the terminal sets the value of the identification bit to 1, which indicates that the first network signal quality is smaller than the first threshold value.
2. The terminal indicates whether the first signal quality is less than a first threshold value by the magnitude of the parameter value of the first signal quality by encapsulating the parameter value of the first signal quality in the first indication information.
In a possible example, the terminal directly encapsulates the parameter value of the first signal quality in the first indication information and sends the encapsulated parameter value of the first signal quality to the network device. After receiving the first indication information, the network device analyzes the first indication information to obtain a parameter value of the first signal quality of the first communication network, compares the parameter value of the first signal quality with a first threshold value, and determines whether the first signal quality is smaller than the first threshold value.
In the embodiment of the present application, the first threshold may be, but is not limited to, determined by any one of the following ways:
1. the terminal determines the first threshold by receiving configuration information of the network device, where the configuration information configures the first threshold.
2. A terminal manufacturer sets a first threshold value in a terminal system; and the first threshold is a value agreed upon by the terminal with the network device.
Step 330, receiving second indication information sent by the network device, and releasing the first communication network based on the second indication information.
In the embodiment provided by the application, after the terminal sends the first indication information to the network and informs the network device that the signal quality of the current first communication network is poor, the network device can reconfigure the network state of the terminal to ensure that the terminal can normally communicate, so that the terminal is disconnected from the first communication network with poor signal quality.
It can be understood that after the network device receives the first indication information, it determines that the quality of the first communication network currently accessed by the terminal is poor, and then sends the second indication information to the terminal; the terminal is instructed to deactivate the first communication network by the second instruction information. In this way, after receiving the second indication information sent by the network, the terminal deactivates the first communication network based on the second indication information, disconnects the first communication network, i.e. releases the first communication network.
In an alternative embodiment of the present application, the second indication information is carried in radio resource control RRC connection reconfiguration information. That is, the network device may instruct the terminal to release the first communication network through the RRC connection reconfiguration information.
In summary, in the off-screen state, the terminal informs the network device that the signal quality of the current first communication network is poor by sending the first indication information to the network device, so as to guide the network device to send the second indication information to the terminal, reconfigure the network of the terminal based on the second indication information, and release the first communication network; therefore, the connection of a communication network is reduced, the power consumption of the terminal is saved, and the endurance time of the terminal is prolonged.
Based on the above embodiment, in step 320, specific implementations of sending the first indication information to the network device by the terminal are various, and two implementations are described in detail below: mode one and mode two. The following are provided:
mode one
In the embodiment of the present application, the implementation process of sending the first indication information to the network device by the terminal is:
setting a signal quality measurement value of a first signal of a first communication network as a first parameter; the first parameter is less than a first threshold; and sending the first parameter carried in the first indication information to the network equipment.
Here, the first Signal refers to a Reference Signal (RS) of the first communication network; the signal quality magnitude of the first signal may be indicative of a current state of the first communication network. The greater the signal quality of the first signal, the better the condition of the first communication network is characterized. Conversely, the smaller the signal quality of the first signal, the worse the state of the first communication network is characterized.
It can be understood that when the terminal detects that the screen state is in the off-screen state, the measured value of the first signal quality is set as a first parameter; the first parameter is less than a first threshold. That is, the terminal sets the signal quality measurement value of the first signal of the current first communication network to a first parameter smaller than the first threshold value, regardless of whether the signal quality measurement value of the first signal is larger than the first threshold value or smaller than the first threshold value. In this way, the first signal quality of the current first communication network is indicated by the first parameter as poor, i.e. the network state of the first communication network is not good. And the first parameter is loaded into the first indication information and sent to the network equipment so as to guide the network equipment to reconfigure the network of the terminal more easily, and the first communication network is deactivated, so that the connection of one communication network is reduced, the power consumption of the terminal is saved, and the duration of the terminal is prolonged.
In one possible implementation, the manner in which the terminal sets the signal quality measurement value of the first signal of the first communication network as the first parameter may include: the first parameter is acquired and is used as a measurement value of the signal quality of the first signal.
The first parameter may be a parameter preset by the terminal, or may be a parameter dynamically set by the terminal based on a first threshold, or may be configured by the network device; as long as the first parameter is guaranteed to be smaller than the first threshold value. The source of the first parameter is not limited in this embodiment of the present application.
It can be understood that in this implementation manner, when the terminal determines that the screen state is the off-screen state, the terminal does not need to measure the signal quality of the first signal of the first communication network, directly sets the signal quality measurement value of the first signal as the first parameter, indicates that the signal quality of the first signal is poor, can reduce the processing time of the network connection, and improves the processing efficiency of the network connection.
In another implementation, the manner in which the terminal sets the signal quality measurement value of the first signal of the first communication network as the first parameter may include: a signal quality measurement of a first signal of a first communication network is obtained, and the signal quality measurement of the first signal of the first communication network is reduced to a first parameter.
In practical application, when the terminal is just accessed to the first communication network and the second communication network, the terminal can measure the signal quality of the first signal of the first communication network, the second signal of the second communication network and the signal of the adjacent cell based on the measurement configuration information sent by the network equipment. Here, the second signal refers to an RS of the second communication network.
In this embodiment of the present application, when the terminal detects that the screen state is the off-screen state, the signal quality measurement value of the first signal of the first communication network may be obtained, and the signal quality measurement value of the first signal is modified, so that the measurement value of the first signal is reduced to be the first parameter value. That is, the measure of the signal quality of the reduced first signal may be indicative of a poor first signal quality of the first communication network.
In practical application, after detecting that the measured values of the first signal, the second signal and the signal of the neighboring cell meet a certain measurement event, the terminal generates a measurement report, and reports the measurement report to the network device.
In the embodiment provided in the present application, the first indication information may be a measurement report of a certain measurement event.
The LTE system and the NR system can support various measurement event reporting, and specifically comprise the following steps:
A1 event: the signal quality of the serving cell is above a threshold;
a2 event: the signal quality of the serving cell is below a threshold;
a3 event: the signal quality of the same frequency/different frequency neighbor cell is higher than that of the serving cell by a threshold;
a4 event: the signal quality of the adjacent cell is higher than a threshold;
a5 event: the signal quality of the serving cell is lower than a first threshold, and the signal quality of the neighbor cell is higher than a second threshold;
b1 event: the signal quality of the neighboring cells of the different systems is higher than a threshold
B2 event: the signal quality of the serving cell is below a first threshold and the signal quality of the inter-system neighbor cell is above a second threshold.
In a possible embodiment, the first indication information may be a measurement report of an A2 event. That is, the terminal indicates that the signal quality of the current first communication network is poor by reporting a measurement report of the A2 event to the network device. And the first threshold is a threshold for judging the quality of the service cell, which is set in the A2 event.
In a possible embodiment, the measurement of the first signal of the first communication network by the terminal is implemented by the terminal modem protocol layer. In the embodiment provided in the application, the terminal modulates and demodulates the first signal through the first modem shown in fig. 2.
Mode two
In the embodiment of the present application, the implementation process of sending the first indication information to the network device by the terminal is:
acquiring a second threshold value; the second threshold is greater than the first threshold; and if the signal quality measured value of the first signal of the first communication network is smaller than the second threshold value, sending the first indication information to network equipment.
In the embodiment provided by the application, when the terminal detects that the screen state is the off-screen state, the signal quality of the first signal of the first communication network is measured, and when the signal quality of the first signal is lower than the second threshold value, the first indication information is reported to the network equipment to indicate that the signal quality of the first communication network is poor.
Here, the first indication information may be a measurement report corresponding to the measurement event.
In this embodiment of the present application, the second threshold is greater than the first threshold, which may be understood that the terminal increases the threshold (i.e., the second threshold) for reporting the first indication information. For example, when detecting that the signal quality of the first signal is less than-110 dbm (first threshold), the original terminal sends first indication information to the network device, and indicates that the signal quality of the first signal is poor, so as to request the network device to reconfigure the network state of the terminal; however, in the embodiment of the present application, when the terminal detects that the signal quality of the first signal is less than-90 dbm (second threshold value), the terminal reports first indication information to the network device, which indicates that the signal quality of the current first signal is poor, and requests the network device to reconfigure the network of the terminal.
In the embodiment of the application, the threshold value of the first indication information is improved, so that the terminal can send the first indication information to the network equipment more easily, the network equipment is guided to send the second indication information, the network of the terminal is reconfigured, the terminal releases the first communication network, the connection of one communication network is reduced, the power consumption of the terminal is saved, and the duration of the terminal is prolonged.
In the present embodiment, the second threshold may be, but is not limited to being, determined by any one of the following means:
(1) And the terminal receives configuration information of the network equipment, and the configuration information configures the second threshold value. The configuration information here may be measurement configuration information.
(2) The terminal manufacturer sets a second threshold in the terminal system.
In a possible implementation, the first indication information may be a measurement report of an A2 event. That is, the terminal indicates that the signal quality of the current first communication network is poor by reporting a measurement report of the A2 event to the network device. The first threshold is a threshold for judging the quality of the service cell, which is set in the common A2 event, and the second threshold is an updated threshold for judging the quality of the service cell.
In a possible embodiment, the measurement of the first signal of the first communication network by the terminal is implemented by the terminal modem protocol layer. In the embodiment provided in the application, the terminal modulates and demodulates the first signal through the first modem shown in fig. 2.
In one possible example, referring to fig. 4, the network connection method provided in the present application includes:
s1, a terminal acquires a screen state and a network connection state;
s2, the terminal judges whether the screen is in a screen-off state or not and is in a double-connection EN-DC state, if yes, the following step S3 is executed;
s3, the terminal sends first indication information to the network equipment, wherein the first indication information characterizes poor signal quality of the NR network;
s4, the terminal receives second indication information sent by the network equipment, and the NR network is released based on the second indication information.
In an optional embodiment of the present application, determining the screen state of the screen may include:
detecting whether a first instruction is received; the first instruction is used for starting an intelligent connection mode with the first communication network; and if the first instruction is received, acquiring the screen state of the terminal.
Here, the first instruction is for initiating an intelligent connection mode of the terminal with the first communication network. In the intelligent connection mode, the terminal may determine whether to connect to the first communication network based on the state in which the terminal is in itself.
