Based on the above mobile terminal hardware structure and the communication network system, various embodiments of the method of the present invention are provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating an embodiment of a network switching method according to the present invention.
In an embodiment, a network switching method is applied to a mobile terminal, where the mobile terminal supports 4G and 5G networks, and the network switching method includes:
step S10, when the mobile terminal resides in a 4G network system, detecting whether N first type data packets are continuously received or continuously transmitted, wherein N is a positive integer greater than or equal to 2, and the length of the first type data packets is greater than a first preset byte number;
in this embodiment, when the mobile terminal resides in the 4G network system, 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 byte number, and if the length of the data packet is greater than the first preset byte number, determine that the data packet is a first type of data packet. For example, when the mobile terminal resides in the 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 by comparing and finding that the length of the data packet is greater than the first preset byte number. The first preset byte number is set according to actual needs, for example, is set to 5k. 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, N consecutive data packets of the first type are received, it is indicated that there is a large amount of data to be transmitted currently. In this embodiment, the specific value of N is not limited, and N is set according to actual needs, for example, set to 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 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 the first type data packet. For example, when the mobile terminal resides in the 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 by comparing and finding that the length of the data packet is greater than the first preset byte number. The first preset byte number is set according to actual needs, for example, is set to 5k. It is easy to understand that when N data packets are continuously transmitted and the length of each data packet is greater than the first preset number of bytes, that is, N data packets of the first type are continuously transmitted, it is indicated that there is a large amount of data to be transmitted currently. In this embodiment, the specific value of N is not limited, and N is set according to actual needs, for example, set to 20.
Step S20, if N first type data packets are continuously received or continuously transmitted, the current network system is switched from the 4G network system to the 5G network system.
In this embodiment, if N continuous first class data packets are received, it is indicated that there is a large amount of data 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, thereby improving the data transmission efficiency. If N first-class data packets are continuously sent, the fact that a large amount of data needs to be transmitted is also indicated, and in this case, the current network system is switched from the 4G network system to the 5G network system for data transmission under the 5G network system, so that the data transmission efficiency is improved.
In this embodiment, when the mobile terminal resides in a 4G network system, detecting whether N first type data packets are continuously received or continuously transmitted, where N is a positive integer greater than or equal to 2, and a length of the first type data packets is greater than a first preset byte number; and if the N first type data packets are continuously received or continuously transmitted, switching the current network system from the 4G network system to the 5G network system. Through the embodiment, when the mobile terminal resides in the 4G network system, if it is detected that there is a large amount of data to be transmitted currently, the current network system is switched from the 4G network system to the 5G network system, so as to perform data transmission in the 5G network system. Because the data transmission rate of the 5G network is obviously better than that of the 4G network for a large amount of data, the time required for data transmission can be greatly shortened by adopting the 5G network for data transmission compared with the 4G network, namely the data transmission efficiency is obviously improved. In this embodiment, only for the scenario that 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 is output, so that the situation that even if the 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 is avoided.
Further, in an embodiment of the network switching method of the present invention, step S20 includes:
step S201, if N first class data packets are continuously received or continuously sent, a first network transmission rate corresponding to the 4G network system is obtained, and the current network system is switched from the 4G network system to the 5G network system.
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 detecting that N first-class data packets are continuously received or continuously sent, the method invokes the current data transmission parameters, acquires the network transmission rate from the data transmission parameters, takes the network transmission rate acquired from the data transmission parameters as the first network transmission rate corresponding to the 4G network system, and then switches the current network system 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 improved after the network system is subsequently switched 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 if the network transmission rate is not obviously improved after the network system is switched 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 view of saving the energy consumption of the terminal).
Based on the foregoing embodiments, in an embodiment of the network switching method of 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 improvement rate according to the first network transmission rate and the second network transmission rate; and when the transmission rate lifting rate is smaller than a preset lifting rate, switching the current network system from the 5G network system to the 4G network system.
In this embodiment, it is considered that in some special cases, for example, the terminal is in a position with poor network coverage, at this time, the network transmission rate of the terminal in the 4G network system is very small compared with the network transmission rate of the terminal in the 5G network system, and using the 5G network also greatly increases the terminal energy consumption compared with the 4G network. Therefore, after step S201, the second network transmission rate corresponding to the 5G network system is further obtained, and the transmission rate improvement rate is calculated according to the first network transmission rate and the second network transmission rate, where the formula for calculating the transmission rate improvement rate is:
wherein R is the transmission rate increase rate, R 1 For the first network transmission rate, R 2 Is the second network transmission rate. When R is smaller than the preset lifting rate, it is indicated that after the network system is switched from the 4G network system to the 5G network system, the network transmission rate is only slightly lifted, the 5G network is used for data transmission, the transmission rate cannot be greatly lifted, and the energy consumption of the terminal can be greatly increased, so that in this case, the current network system is switched from the 5G network systemAnd switching the system to a 4G network system. Thereby avoiding unnecessary increase of the power consumption of the terminal.
Further, in an embodiment of the network switching method of the present invention, after the transmission rate improving rate is calculated according to the first network transmission rate and the second network transmission rate, the method further includes:
when the transmission rate increasing rate is greater than or equal to a preset increasing rate, detecting whether M second-class data packets are continuously received or continuously sent, wherein M is a positive integer greater than or equal to 2, and the length of the second-class data packets is smaller than a second preset byte number; if M second class data packets are continuously received or continuously transmitted, the current network system is switched 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 indicated that the data transmission using the 5G network is significantly better than the data transmission using the 4G network, so that the network system is kept unchanged, but considering that the data amount is smaller in the later stage of data transmission, it is not necessary to use the 5G network for data transmission. Therefore, when the transmission rate increasing rate is greater than or equal to the preset increasing rate, the IP layer is monitored to acquire 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 judged, if the length of the data packet is smaller than the second preset byte number, the data packet is determined to be the second type data packet. For example, when the mobile terminal resides in the 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 the second type data by comparing and finding that the length of the data packet is smaller than the second preset byte number. The second preset byte number is set according to actual needs, for example, 1.5k. It is easy to understand that when N data packets are continuously received and the length of each data packet is smaller than the second preset byte number, that is, when N continuous second class data packets are received, it is indicated that the amount of data to be transmitted is relatively small, and the data transmission work can be completed relatively quickly even through the 4G network, so that the network system needs to be switched from the 5G network system to the 4G network system in view of saving the energy consumption of the terminal. In this embodiment, the specific value of N is not limited, and N is set according to actual needs, for example, set to 20.
When the transmission rate increase rate is greater than or equal to the preset increase rate, it is indicated that the use of the 5G network for data transmission is significantly better than the use of the 4G network for data transmission, so that the network system is kept unchanged, but it is considered that the use of the 5G network for data transmission is unnecessary when the data amount is smaller in the later stage of data transmission. Therefore, when the transmission rate increasing rate is greater than or equal to the preset increasing rate, the IP layer is monitored to acquire 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, if the length of the data packet is smaller than the second preset byte number, the data packet is determined to be the second type data packet. For example, when the mobile terminal resides in the 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 the second type data by comparing and finding that the length of the data packet is smaller than the second preset byte number. The second preset byte number is set according to actual needs, for example, 1.5k. 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 byte number, that is, N second class data packets are continuously sent, it is indicated that the amount of data to be transmitted is relatively small, and the data transmission work can be completed relatively quickly even through the 4G network, so that the network system needs to be switched from the 5G network system to the 4G network system in view of saving energy consumption of the terminal. In this embodiment, the specific value of N is not limited, and N is set according to actual needs, for example, set to 20.
Further, in an embodiment of the network switching method of the present invention, the switching the current network system from the 5G network system to the 4G network system includes:
and when the current residual electric quantity of the mobile terminal is smaller than the preset electric quantity, switching the current network system from the 5G network system to the 4G network system.
In the above embodiment, when the network transmission rate of the 5G network system is not higher than that of the 4G network system, or when the amount of data to be transmitted is smaller, the network system needs to be switched from the 5G network system to the 4G network system in consideration of saving the terminal energy consumption. In this embodiment, when the network transmission rate of the 5G network system is not higher than that of the 4G network system, or when the amount of data to be transmitted is smaller, if the current remaining power of the mobile terminal is smaller 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:
when the occurrence times of network system switching events in the preset time period are detected to be greater than or equal to the preset times, the N value is adjusted to be a new N value, the first preset byte number is adjusted to be a new first preset byte number, the M value is adjusted to be a new M value, the second preset byte number is adjusted to be a new second preset byte number, the preset lifting rate is adjusted to be a new preset lifting rate, wherein the new N value is greater than the N value, the new first preset byte number is greater than the first preset byte number, the new M value is greater than the M value, and 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.
In this embodiment, since frequent network switching affects normal use of the terminal and increases power consumption of the terminal, when the number of occurrences of a network system switching event (from a 4G network system to a 5G network system or from a 5G network system to a 4G network system is all network system switching events) within a preset period (e.g., 10 minutes) is greater than or equal to a preset number of times (e.g., 5 times), the N value, the first preset byte number, the M value, the second preset byte number, and the preset lifting rate need to be adjusted to reduce the number of occurrences of the network system switching event. Wherein the new N value is greater than the N value, the new first predetermined number of bytes is greater than the first predetermined number of bytes, the new M value is greater than the M value, the new second predetermined number of bytes is less than the second predetermined number of bytes, and the new predetermined rate of increase is less than the predetermined rate of increase.
