Description

Network switching method, mobile terminal and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a network switching method, a mobile terminal, and a computer-readable storage medium.

Background

With the rapid development of 5G technology, 5G terminals have begun to be gradually commercialized. Although the maximum transmission rate of a 5G network is much higher than that of a 4G network, many applications do not require high rate support in terminal use. Such as WeChat text chatting, surfing the web for news, and the like. That is to say, from the experience effect, in many scenarios with low speed requirement, the difference between 4G and 5G is not very large, and the power consumption of the terminal is greatly increased by using the 5G network compared with using the 4G network. Under the circumstances, how to perform network handover to reduce power consumption of the terminal becomes a problem of great concern in the industry.

In the prior art, whether to switch the network to 5G is determined by the current application scenario of the terminal, such as whether to perform downloading work. By such switching conditions, even when a file with a relatively small data volume is downloaded, the file is switched to the 5G network to perform the downloading operation. However, for a file with a relatively small data size, even if the downloading operation is performed through the 4G network, the required time is very small compared with the 5G network. That is, the downloading operation is performed through the 5G network, which cannot significantly shorten the data transmission time, but increases the power consumption of the terminal.

Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Referring to fig. 3, fig. 3 is a flowchart illustrating a network switching method according to an embodiment of the present invention.

In an embodiment, a network handover method is applied to a mobile terminal, where the mobile terminal supports 4G and 5G networks, and the network handover method includes:

step S10, when the mobile terminal resides in a 4G network system, detecting whether N first-class data packets are continuously received or sent, wherein N is a positive integer greater than or equal to 2, and the length of the first-class data packets is greater than a first preset byte number;

in this embodiment, when the mobile terminal resides in the 4G network standard, the IP layer is monitored to obtain the length of each data packet received by the mobile terminal, and determine whether the length of the data packet is greater than a first preset number of bytes, and if the length of the data packet is greater than the first preset number of bytes, determine that the data packet is a first type of data packet. For example, when the mobile terminal resides in a 4G network system, a data packet is received at a certain time, the length of the data packet is obtained by analyzing the data packet, and the data packet is marked as the first type of data if the length of the data packet is found to be greater than a first preset number of bytes by comparison. The first preset number of bytes is set according to actual needs, for example, set to 5 k. It is easy to understand that when N data packets are received consecutively and the length of each data packet is greater than the first preset number of bytes, that is, the N consecutive data packets of the first type are received, it indicates that a large amount of data needs to be transmitted currently. In this embodiment, a specific value of N is not limited, and N is set according to an actual requirement, for example, 20.

When the mobile terminal resides in the 4G network system, the IP layer is monitored, the length of each data packet sent by the mobile terminal can be obtained, whether the length of the data packet is larger than a first preset byte number or not is judged, and if the length of the data packet is larger than the first preset byte number, the data packet is determined to be a first type data packet. For example, when the mobile terminal resides in a 4G network system, a data packet is sent at a certain time, the length of the data packet is obtained by analyzing the data packet, and the data packet is marked as the first type of data if the length of the data packet is found to be greater than a first preset number of bytes by comparison. The first preset number of bytes is set according to actual needs, for example, set to 5 k. It is easy to understand that when N data packets are continuously sent and the length of each data packet is greater than the first preset number of bytes, that is, N first type data packets are continuously sent, it indicates that a large amount of data needs to be transmitted currently. In this embodiment, a specific value of N is not limited, and N is set according to an actual requirement, for example, 20.

Step S20, if N first-type data packets are continuously received or continuously sent, switching the current network system from the 4G network system to the 5G network system.

In this embodiment, if N consecutive first-type data packets are received, it is indicated that a large amount of data needs to be transmitted currently, and in this case, the current network system is switched from the 4G network system to the 5G network system, so that data transmission is performed in the 5G network system, and thus, the data transmission efficiency is improved. If N first-class data packets are continuously sent, it is also indicated that a large amount of data needs to be transmitted currently, and in this case, the current network system is switched from the 4G network system to the 5G network system for data transmission in the 5G network system, so that the data transmission efficiency is improved.

In this embodiment, when the mobile terminal resides in a 4G network standard, it is detected whether N first-type data packets are continuously received or continuously sent, where N is a positive integer greater than or equal to 2, and the length of the first-type data packet is greater than a first preset number of bytes; and if N first-class data packets are continuously received or continuously sent, switching the current network standard from the 4G network standard to the 5G network standard. Through the embodiment, when the mobile terminal resides in the 4G network system, if it is detected that a large amount of data needs to be transmitted currently, the current network system is switched from the 4G network system to the 5G network system, so that data transmission can be performed in the 5G network system. For a large amount of data, the data transmission rate of the 5G network is obviously better than that of the 4G network, so that compared with the data transmission of the 4G network, the data transmission of the 5G network can greatly shorten the time required by the data transmission, that is, the data transmission efficiency is obviously improved. In addition, in this embodiment, only for a scene in which a large amount of data needs to be transmitted, the current network system is switched from the 4G network system to the 5G network system, instead of switching the current network system from the 4G network system to the 5G network system as long as data output is performed, which avoids the situation that even if the current network system is switched to the 5G network, the data transmission efficiency cannot be obviously improved, and the power consumption of the terminal is increased instead.

Further, in an embodiment of the network handover method of the present invention, step S20 includes:

step S201, if N first-type data packets are continuously received or continuously sent, acquiring a first network transmission rate corresponding to the 4G network standard, and switching the current network standard from the 4G network standard to the 5G network standard.

In this embodiment, if N first-type data packets are continuously received or continuously sent, a first network transmission rate corresponding to the 4G network system is obtained. The first network transmission rate refers to a real-time network transmission rate in a 4G network system. When N first-class data packets are detected to be continuously received or continuously sent, the current data transmission parameters are called, the network transmission rate is obtained from the data transmission parameters, the network transmission rate obtained from the data transmission parameters is used as the first network transmission rate corresponding to the 4G network system, and then the current network system is switched from the 4G network system to the 5G network system.

In this embodiment, the first network transmission rate corresponding to the 4G network system is obtained, so as to determine whether the network transmission rate is greatly increased after subsequent switching to the 5G network system, thereby determining whether the network system needs to be switched from the 5G network system to the 4G network system (because the network transmission rate is not significantly increased after switching from the 4G network system to the 5G network system, the network system should be switched from the 5G network system to the 4G network system in consideration of saving terminal energy consumption).

On the basis of the foregoing embodiment, in an embodiment of the network switching method according to the present invention, after step S201, the method further includes:

acquiring a second network transmission rate corresponding to the 5G network system; calculating to obtain a transmission rate increase rate according to the first network transmission rate and the second network transmission rate; and when the transmission rate increasing rate is smaller than the preset increasing rate, switching the current network standard from the 5G network standard to the 4G network standard.

In this embodiment, it is considered that in some special cases, for example, the terminal is located at a position with poor network coverage, at this time, the difference between the network transmission rate of the terminal in the 4G network system and the network transmission rate of the terminal in the 5G network system is very small, and the use of the 5G network greatly increases the energy consumption of the terminal compared with the 4G network. Therefore, after step S201, a second network transmission rate corresponding to the 5G network system is further obtained, and a transmission rate increase rate is calculated according to the first network transmission rate and the second network transmission rate, where a formula for calculating the transmission rate increase rate is as follows:

wherein R is the transmission rate increase rate, R ₁Is a first network transmission rate, R ₂Is the second network transmission rate. When R is smaller than the preset lifting rate, the network transmission rate is only slightly improved after the network standard is switched from the 4G network standard to the 5G network standard, the transmission rate cannot be greatly improved by using the 5G network for data transmission, and the energy consumption of the terminal is also greatly increased, so that the current network standard is switched from the 5G network standard to the 4G network standard under the condition. Thereby avoiding unnecessary increase of the energy consumption of the terminal.

Further, in an embodiment of the network handover method of the present invention, after obtaining the transmission rate increase rate by calculating according to the first network transmission rate and the second network transmission rate, the method further includes:

when the transmission rate increase rate is greater than or equal to a preset increase rate, detecting whether M second-class data packets are continuously received or sent, wherein M is a positive integer greater than or equal to 2, and the length of each second-class data packet is smaller than a second preset byte number; and if M second-type data packets are continuously received or sent, switching the current network system from the 5G network system to the 4G network system.

In this embodiment, when the transmission rate increase rate is greater than or equal to the preset increase rate, it is described that data transmission using the 5G network is significantly better than data transmission using the 4G network, so that the network format is kept unchanged, but considering that the data volume is small in the later stage of data transmission, it is not necessary to use the 5G network for data transmission. Therefore, when the transmission rate increase rate is greater than or equal to the preset increase rate, the IP layer is monitored to obtain the length of each data packet received by the mobile terminal, and whether the length of the data packet is smaller than the second preset byte number is determined, and if the length of the data packet is smaller than the second preset byte number, the data packet is determined to be a second-class data packet. For example, when the mobile terminal resides in a 5G network system, a data packet is received at a certain time, the length of the data packet is obtained by analyzing the data packet, and the data packet is marked as second-class data if the length of the data packet is found to be smaller than a second preset number of bytes by comparison. The second preset number of bytes is set according to actual needs, for example, set to 1.5 k. It is easy to understand that when N data packets are received continuously and the length of each data packet is smaller than the second preset number of bytes, that is, when N second-type data packets are received continuously, it indicates that the amount of data to be transmitted is relatively small, and data transmission can be completed quickly even through a 4G network, so that the network system needs to be switched from the 5G network system to the 4G network system in order to save terminal energy consumption. In this embodiment, a specific value of N is not limited, and N is set according to an actual requirement, for example, 20.

When the transmission rate increase rate is greater than or equal to the preset increase rate, it is indicated that the data transmission using the 5G network is obviously better than the data transmission using the 4G network, so that the network format is kept unchanged, but considering that the data volume is small in the later period of data transmission, the data transmission using the 5G network is not necessary. Therefore, when the transmission rate increase rate is greater than or equal to the preset increase rate, the IP layer is monitored to obtain the length of each data packet sent by the mobile terminal, and whether the length of the data packet is smaller than the second preset byte number is judged, and if the length of the data packet is smaller than the second preset byte number, the data packet is determined to be a second-class data packet. For example, when the mobile terminal resides in a 5G network system, a data packet is sent at a certain time, the length of the data packet is obtained by analyzing the data packet, and the data packet is marked as second-type data if the length of the data packet is found to be smaller than a second preset number of bytes by comparison. The second preset number of bytes is set according to actual needs, for example, set to 1.5 k. It is easy to understand that when N data packets are continuously sent and the length of each data packet is smaller than the second preset number of bytes, that is, N second-type data packets are continuously sent, it indicates that the amount of data to be transmitted is relatively small, and data transmission can be completed quickly even through a 4G network, so that the network system needs to be switched from a 5G network system to a 4G network system in order to save terminal energy consumption. In this embodiment, a specific value of N is not limited, and N is set according to an actual requirement, for example, 20.

Further, in an embodiment of the network switching method of the present invention, switching the current network standard from the 5G network standard to the 4G network standard includes:

In the above embodiment, when the network transmission rate of the 5G network system is not high compared with that of the 4G network system, or the amount of data to be transmitted is small, the energy consumption of the terminal is saved, and the network system needs to be switched from the 5G network system to the 4G network system. In this embodiment, when the network transmission rate of the 5G network system is not high compared with that of the 4G network system, or the amount of data to be transmitted is small, if the current remaining power of the mobile terminal is less than the preset power, the current network system is switched from the 5G network system to the 4G network system.

Further, in an embodiment of the network switching method of the present invention, the network switching method further includes:

In this embodiment, since frequent network switching may affect normal use of the terminal and may also increase power consumption of the terminal, when the occurrence number of network scheme switching events (from a 4G network scheme to a 5G network scheme, or from a 5G network scheme to a 4G network scheme) within a preset time duration (for example, 10 minutes) is greater than or equal to a preset number (for example, 5 times), the N value, the first preset number of bytes, the M value, the second preset number of bytes, and the preset boost rate need to be adjusted to reduce the occurrence number of network scheme switching events. The new N value is larger than the N value, the new first preset byte number is larger than the first preset byte number, the new M value is larger than the M value, the new second preset byte number is smaller than the second preset byte number, and the new preset lifting rate is smaller than the preset lifting rate.
