Detailed Description
Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
The development of mobile communication technology is an evolution process, so that a plurality of mobile communication networks with different standards are merged in the network. For example, in the current 4G network and 5G network, a terminal can generally support multiple terminal systems simultaneously, and access to networks of different systems for service transmission according to different requirements. A terminal that supports multiple mobile communication systems at the same time is called a multimode terminal. The conventional terminal performs network handover mainly considering the following situations:
1. the network access speed is accelerated, so that the terminal can be ensured to be quickly and accurately accessed to the correct network, and the network access time is reduced.
2. The success rate of accessing the network is improved, and the success rate of accessing the terminal can be improved according to the strategy under the condition that multiple networks or the network is busy.
3. The communication quality is improved, and under the multi-network environment and different network bandwidths and busy degrees, the communication bandwidth of the terminal can be increased better by selecting the network.
4. The network operation efficiency is improved, and how to balance the terminal load under the multi-touch network condition enables the whole network operation efficiency to be higher.
5. How to select the network on the dual-card terminal can save more expenses.
In order to solve the problems, the technology is optimized through a core network, optimized through a base station, optimized through adding network element equipment, and a network selection strategy of pre-storing a network priority list through terminal equipment.
However, in the evolution from 4G to 5G, a new problem arises that has not occurred in the previous network upgrade generations: communication between a terminal and a base station in a 5G network may cause the terminal to generate significantly more power consumption than in a 4G network. For example, when a mobile phone user uses WeChat chat, microblog swiping, mobile phone reading, mobile phone map, shopping and other daily uses, the 4G network speed is enough to ensure that the data acquired at one time is updated in place within 1 second, the 5G transmission is also within 1 second, the experience cannot be perceived differently, and the power consumption is much larger.
Then, in the case that the 4G and 5G networks coexist, if the network is selected based on the network setting or the network signal, the terminal may be always in the 5G network, and the 4G network may meet the service of the experience requirement, which will cause additional consumption of the terminal power.
Therefore, the embodiment of the application provides a network switching method, which can help terminal equipment to save energy, reduce consumption and prolong service time on the basis of ensuring user experience.
Fig. 1 is a flowchart of a network handover method according to an embodiment, and as shown in fig. 1, the method according to the embodiment includes the following steps.
Step S1010, receiving a network selection priority strategy input by an application program, wherein the network selection priority strategy comprises speed priority or power consumption priority.
The network switching method provided in this embodiment is applied to a terminal in a mobile communication network, where the terminal may also be referred to as User Equipment (UE). The terminal in the embodiment of the present application may support at least two networks at the same time, and the environment where the terminal is located is an environment where at least two networks coexist, where the two networks are, for example, a first network and a second network.
In the conventional network switching mechanism, the network side instructs the terminal to switch the network according to the state of the network, but only the factors of the network side are considered, and the relevant factors of the terminal are not considered. Since power consumption generated by terminals performing the same service data transmission in different networks may be greatly different, generally, the higher the transmission rate, the higher the power consumption in the network. With the development of mobile communication technology, the data transmission rate in the network with a lower transmission rate is sufficient to meet the data transmission requirements of most services, and then the network selection is performed only according to the network switching mechanism at the network side, which may cause the service data transmission that may be originally completed in the low power consumption network to be performed in the high power consumption network, thereby possibly bringing extra power consumption to the terminal. In the embodiment of the present application, a network with high power consumption and high data transmission rate is a 5G network, and a network with low power consumption and low data transmission rate is a 4G network, for example, but the first network and the second network are not limited to the 5G network and the 4G network, and for example, as the networks evolve, the first network and the second network may also be a 6G network and a 5G network or a 6G network and a 4G network, and the like.
Therefore, in this embodiment, the network switching is selected according to the service transmission requirements of different applications in the terminal. Different application programs can have different network selection priority strategies according to the transmission characteristics of the service data, for example, the transmission quantity of the service data is not large, and the real-time requirement on data transmission is not high, so that the 4G network can sufficiently meet the transmission requirement; however, if the transmission amount of service data is large or the requirement on the real-time performance of data transmission is high, the service needs to be transmitted by the 5G network. Different application programs can be preset with different network selection priority strategies, wherein the network selection priority strategies comprise speed priority or power consumption priority. Wherein the speed priority means that the service transmission of the application requires a faster transmission rate and higher real-time performance, and the power consumption priority means that the service transmission of the application does not require a faster transmission rate and higher real-time performance. The application program is a user of the data service, and taking the android system as an example, WeChat, microblog, browser, map software and the like are all application programs of the data service.
The network selection priority policy may also be determined in real time according to different requirements of the application program for transmitting the service data each time, that is, the network selection priority policy is obtained by calculating the required rate of the application program for transmitting the service data or the size and the expected time of the service data to be transmitted according to the required rate of the application program for transmitting the service data, and then comparing the required rate of the application program for transmitting the service data with a preset threshold.
Step S1020, performing network switching according to the network selection priority policy, where the network switching is performed to a first network when the network selection priority policy is speed priority, or to a second network when the network selection priority policy is power consumption priority, a data transmission rate of the first network is higher than a data transmission rate of the second network, and power consumption of the terminal in the first network is higher than power consumption of the terminal in the second network.
And after receiving the network selection priority strategy, switching the network according to the network selection priority strategy, wherein the network selection priority strategy is switched to a first network when the speed is first, and the network selection priority strategy is switched to a second network when the power consumption is first. When the application program needs the speed priority, the first network can be accessed preferentially to ensure that the service transmission rate of the application program meets the requirement, and when the application program does not have high requirement on the data transmission rate, the second network can be accessed to save the electric quantity of the terminal on the basis of meeting the requirement of the user.
In an embodiment, since the network currently activated by the terminal may be the first network or the second network, the network switching is performed according to the network selection priority policy, which includes one or more of the following policy manners: if the currently activated network is the second network and the network selection priority policy is speed priority, switching to the first network; if the current activated network is the second network and the network selection priority policy is power consumption priority, directly initiating a data service; if the current activated network is the first network and the network selection priority policy is speed priority, directly initiating a data service; and if the currently activated network is the first network and the network selection priority policy is power consumption priority, switching to a second network.
The network switching method provided by this embodiment receives a network selection priority policy input by an application, where the network selection priority policy includes speed priority or power consumption priority, and performs network switching according to the network selection priority policy, where the network selection priority policy is switched to a first network when the speed is priority, and the network selection priority policy is switched to a second network when the power consumption is priority, where a data transmission rate of the first network is higher than a data transmission rate of the second network and power consumption of a terminal in the first network is greater than that of the terminal in the second network, so that network switching can be implemented at a terminal side, and power consumption of the terminal is saved on the premise that usage of a user is satisfied.
Fig. 2 is a flowchart of another network handover method according to an embodiment, and as shown in fig. 2, the method according to the embodiment includes the following steps.
Step S2010, receiving the required data transmission rate sent by the application program.
In the embodiment shown in fig. 1, the terminal performs network handover according to the network selection priority policy sent by the application program. However, since the state of the network to which the terminal is currently connected is unclear by the application program, the network is switched and selected only according to the network selection priority policy preset in the application program, and the actual use requirement of the application program cannot be met. The network selection prioritization policy of the application may also be determined in real-time according to the traffic data transmission requirements of the application. In this embodiment, the first network is a 5G network, and the second network is a 4G network.
Then the desired data transfer rate sent by the application program needs to be received first. The desired data transfer rate of the application may be the desired data transfer rate that the application directly sends, for example 50 MB/s. Or the size of the data to be transmitted and the expected sending time sent by the application program, and the required data transmission rate calculated according to the size of the data to be transmitted and the expected sending time. The expected sending time is the longest time length for sending the data to be transmitted, and the service of the application program cannot be influenced until the data to be transmitted is sent within the expected sending time. For example, if the size of data to be transmitted is 120MB and the expected transmission data is 2 seconds, the required data transmission rate is 60 MB/s.
Or the required data transfer rate may be a predefined constant or macro-like value. Similarly, if the application program sends a data SIZE to be transmitted and an expected sending time, the data SIZE to be transmitted may also be a predefined value, such as a constant in the program language, or a value for a macro, such as SIZE _ range _ FILE; the expected transmission time may be a specific time value in minutes, seconds, or milliseconds, or may be a predetermined defined constant, macro, or the like.
In step S2020, it is determined whether the data transfer rate of the available second network satisfies the data transfer rate required by the application.
The 4G network that the terminal can access is called an available 4G network, and the data transmission rate of the terminal for performing service data transmission in the 4G network is an inherent attribute of the network, so that it can be determined whether the data transmission rate of the available 4G network satisfies the data transmission rate required by the application program. Namely, whether the data transmission rate of the available 4G network is greater than the data transmission rate required by the application program or whether the difference value between the data transmission rate of the available 4G network and the data transmission rate required by the application program is within a preset threshold is judged.
In an embodiment, since the signal quality of the 4G network where the terminal is located may affect the data transmission rate of the 4G network, the data transmission rate of the available 4G network may also be an expected data transmission rate calculated by weighting according to the signal quality of the 4G network.
The determining whether the data transfer rate of the available second network satisfies the data transfer rate required by the application includes: when the current activated network is a second network, determining a discount coefficient according to the signal quality of the current network, wherein the discount coefficient is positively correlated with the signal quality of the current network; calculating an expected data transmission rate of the available second network according to the discount coefficient, wherein the expected data transmission rate is the product of an ideal data transmission rate of the available second network and the discount coefficient; it is determined whether the expected data transfer rate of the available second network satisfies the data transfer rate required by the application.
If the current activated network is a 4G network, firstly, the current network signal state is obtained, the network signal is in a normal network state in an interval, and the network signal which is not in the interval is poor, and the data transmission rate of the 4G network is discounted and adjusted. S ═ S1Xk, S is the expected data transmission rate, S1And k is a discount coefficient corresponding to the current network signal for the ideal data transmission rate. The discount coefficient k represents the influence on the data transmission rate under different network signal conditions. The value of k can have a certain functional relationship with the signal intensity, and can also be determined according to product experience. For example, there are several distributions under different network signal strengths, such as: the ideal 4G transmission data rate is 100Mbps, and the network signal is reduced to a certain extent, which causes the network transmission data to be reduced, and the data is classified into several grades according to the signal intensity: 0-1Mbps, 1Mbps-10Mbps, 10Mbps-20Mps, 20-50Mbps and 50-100Mbps, and the corresponding k values are respectively 0.01, 0.1, 0.2, 0.5 and 1. Or the discount coefficient k is in direct proportion to the ratio of the current network signal strength to the preset ideal network signal strength, if the current signal strength is greater than or equal to the preset ideal network signal strength, k is 1, otherwise k is the current network signal strength/the preset ideal network signal strength. The current network signal value is obtained, and the corresponding network signal value can be matchedLet 4G network data rate discount coefficient.
Or when the currently active network is the first network, determining whether the desired data transfer rate of the available second network satisfies the data transfer rate required by the application. That is, if the currently active network is not a 4G network, the discount coefficient is calculated as 1.
Step S2030, if yes, sending a network selection priority policy with priority on power consumption to the application program, otherwise, sending a network selection priority policy with priority on speed to the application program.
If the data transmission rate of the available 4G network meets the data transmission rate required by the application program, it indicates that the available 4G network of the terminal has met the traffic transmission requirement of the application program, and therefore, a network selection priority policy with priority over power consumption may be sent to the application program. If the data transmission rate of the available 4G network does not meet the data transmission rate required by the application program, the available 4G network of the terminal cannot meet the service transmission requirement of the application program, and therefore, a network selection priority strategy with a priority in speed can be sent to the application program.
Step S2040, a network selection priority policy input by the application is received.
Step S2050 is to perform network switching according to the network selection priority policy, where the network selection priority policy is to switch to the first network when the speed is first, and the network selection priority policy is to switch to the second network when the power consumption is first.
Because the network selection priority strategy in the application program is obtained by calculation according to the required data transmission rate sent by the application program and the data transmission rate of the 4G network available for the terminal, after network switching selection is carried out according to the network selection priority strategy sent by the application program, the network accessed by the terminal can meet the service transmission requirement of the application program, and the power consumption of the terminal can be saved.
The network switching method provided by the embodiment shown in fig. 2 is applied to a terminal, and has two interactive interfaces with an application program, namely an interface 1 for receiving a required data transmission rate sent by the application program and an interface 2 for receiving a network selection priority policy input by the application program. The processing methods of the interface 1 and the interface 2 may be processed by using independent processing logics, and fig. 3 and fig. 4 are flowcharts of the processing logics of the interface 1 and the interface 2, respectively.
Fig. 3 is a flowchart of another network switching method according to an embodiment, where the embodiment is a schematic processing logic diagram of an interface 1, and as shown in fig. 3, the method according to the embodiment includes the following steps.
Step S3010, the application calls interface 1, and imports parameters: the size of the data to be transmitted and the expected time.
The SIZE of data to be transmitted refers to the SIZE of data received/transmitted by data service, and may be a specific byte SIZE of a FILE (such as a video FILE), such as 120MB, or a predefined value, such as a constant in a program language, or a value for a macro, such as SIZE _ search _ FILE. The expected time is the time required to transmit data. It may be a specific time value in minutes, seconds, or milliseconds, or it may be a predetermined defined constant, macro, or the like. The size of data to be transmitted and the expected time may also be defined as the data transmission rate per unit time. When such a network application is initialized, although it is not explicitly provided for a user to receive or send a file, the program itself may have data exchanged with it. Therefore, the application program can call the interface to determine what network selection strategy the application program is suitable for according to the design of the application program.
Step S3020, obtaining information of the 4G network available at the current terminal, and obtaining a data transmission rate S in the preset 4G network.
If the current activated network is a 4G network, the current network signal state is obtained, the network signal is in a normal network state in an interval, and the network signal which is not in the interval is poor, the preset 4G network data transmission rate is discounted and adjusted: s ═ S1K, S is the expected data transmission rate, S1And k is a discount coefficient corresponding to the current network signal for the ideal data transmission rate. k is a value ofAccording to the product experience, the new model strengths of different networks have several grades of distributions, such as: the ideal 4G transmission data rate is 100Mbps, and the network signal is reduced to a certain extent, which causes the network transmission data to be reduced, and the data is classified into several grades according to the signal intensity: 0-1Mbps, 1Mbps-10Mbps, 10Mbps-20Mps, 20-50Mbps and 50-100Mbps, and the corresponding k values are respectively 0.01, 0.1, 0.2, 0.5 and 1. And the current network signal value is obtained, so that the corresponding preset 4G network data transmission rate discount coefficient can be matched. If the currently active network is not a 4G network, the discount coefficient is calculated as 1.
Step S3030: calculating expected data transmission rate S according to the size of the data to be transmitted and the expected time2。
Step S3040: expected data transmission rate S2And comparing the expected data transmission rate with the data transmission rate S in the 4G network, and judging whether the expected data transmission rate is smaller than the data transmission rate in the 4G network. If: s2Less than S, or S2If the difference with S is within a predetermined threshold, the 4G network will meet the data transmission rate requirements of the application. The interface returns the priority policy of network selection as follows: power consumption takes precedence. S2If the value of S is larger than the preset threshold value, the 4G network does not meet the data transmission rate requirement of the application, and the selection priority strategy of the interface returning network is as follows: the speed is prioritized.
Fig. 4 is a flowchart of another network switching method according to an embodiment, which is a schematic processing logic diagram of an interface 2, and as shown in fig. 4, the method according to the embodiment includes the following steps.
Step S4010, the application program calls interface 2, and imports parameters: and selecting a priority strategy by the network.
Step S4020, acquires current network information including the currently activated network type.
And according to the strategy of the transmitted parameters, judging by combining the current network information, and initiating the data service or initiating the data service after switching the network. Further, according to the current network condition:
in step S4030, it is determined whether the currently active network is a 4G network or a 5G network.
If the current network is a 4G network: if the incoming network selection policy is 'power consumption first', directly initiating a data service; and if the incoming network selection strategy is 'speed priority', switching the network to the 5G network and then initiating the data service process. If the current network is 5G: if the incoming network selection policy is 'speed priority', directly initiating a data service; if the incoming network selection policy is "power consumption first", then the switching network initiates a data traffic process for the 4G network.
