In the following method embodiments, for convenience of description, only the main execution body of each step is described as a terminal.
The following describes in detail a data transmission method provided in an embodiment of the present application with reference to fig. 2 to 3.
Please refer to fig. 2, which is a flowchart illustrating a data transmission method according to an embodiment of the present disclosure. The present embodiment is exemplified by applying a data transmission method to a terminal, where the data transmission method may include the following steps:
s201, measure the 5G signal strength of the 5G serving cell.
The 5G serving cell is an area where the terminal can obtain a 5G network service, and is a cell divided from the whole 5G communication serving cell, and a 5G base station is arranged in the cell and is responsible for establishing wireless connection with the terminal in the cell, so that the 5G terminal can perform 5G communication in any cell in the 5G communication serving cell.
Generally, when a terminal supporting 5G is in a 5G serving cell, since the coverage of the 5G serving cell is limited, the terminal has different positions in the 5G serving cell, and the received 5G signal strength is different, it is necessary to obtain the position of the 5G serving cell where the terminal resides, and measure the 5G signal strength of the terminal residing in the 5G serving cell.
And S202, when the 5G signal strength is smaller than the first signal strength threshold value and is greater than or equal to the second signal strength threshold value, establishing 5G data connection through the 5G serving cell.
In the embodiment of the present application, the first signal strength threshold refers to a lower limit value of a stronger 5G signal set in the terminal, and when the actual 5G signal strength is greater than or equal to the first signal strength threshold, it indicates that the 5G signal is better at this time, and the terminal can smoothly transmit data through the 5G network; the second signal strength threshold is an upper limit value of a weak 5G signal set in the terminal, and when the actual 5G signal strength is smaller than the second signal strength threshold, the 5G signal is the worst at the moment, and the terminal transmits data through a 5G network to cause data loss; the first signal strength threshold is greater than the second signal strength threshold. The 5G data connection refers to a mode in which a terminal supporting 5G can perform 5G network communication.
Generally, after measuring the 5G signal strength of the 5G serving cell where the terminal is located, the relationship between the 5G signal strength and the first signal strength threshold and the second signal strength threshold needs to be analyzed to determine the type of establishing the data connection: when the 5G signal strength is greater than or equal to the second signal strength threshold value, establishing 5G data connection through the 5G serving cell; and searching for a 4G serving cell when the 5G signal strength is less than the second signal strength threshold, and establishing a 4G data connection through the 4G serving cell.
S203, searching for a 4G serving cell, and establishing a 4G data connection through the 4G serving cell.
The 4G service cell is an area where the terminal can obtain a 4G network service, and is a cell divided from the whole 4G communication service area, and a 4G base station is arranged in the cell and is responsible for establishing wireless connection with the terminal in the cell, so that the 4G terminal can perform 4G communication in any cell in the 4G communication service area. The 4G data connection refers to a mode in which a 4G-capable terminal can perform 4G network communication.
Generally, when it is determined that the 5G signal strength of the 5G serving cell in which the terminal is located is smaller than a first signal strength threshold and is greater than or equal to a second signal strength threshold, it indicates that the current 5G signal is medium, and after a 5G data connection is established through the 5G serving cell, the terminal transmits data through the 5G data connection, which may cause data loss, and it is necessary to transmit data through a 4G data connection at the same time to protect the terminal from successfully completing data transmission; therefore, it is necessary to further search for a 4G serving cell, select a cell with the highest 4G signal strength as the 4G serving cell when a plurality of 4G cells are searched, and establish a 4G data connection through the 4G serving cell.
And S204, transmitting target data through the 4G data connection and the 5G data connection.
The target data is information transmitted by a user through a data connection by using a terminal.
Generally, after the terminal establishes the 4G data connection and the 5G data connection, target data that the user wants to transmit can be transmitted through the 4G data connection and the 5G data connection.
As can be seen from the above, the data transmission method provided in this scheme may measure the 5G signal strength of the 5G serving cell through the terminal, establish a 5G data connection through the 5G serving cell, search for the 4G serving cell, and establish a 4G data connection through the 4G serving cell when the 5G signal strength is less than the first signal strength threshold and is greater than or equal to the second signal strength threshold, and transmit target data through the 4G data connection and the 5G data connection, so that the terminal can transmit data through the 4G network and the 5G network simultaneously when the 5G signal is weak, thereby avoiding a problem of loss of the transmitted data.
Please refer to fig. 3, which is another flow chart illustrating a data transmission method according to an embodiment of the present application. The present embodiment is exemplified by applying a data transmission method to a terminal. The data transmission method may include the steps of:
s301, receiving a measurement configuration message sent by the network equipment.
The measurement configuration message carries one or more of a measurement period, a measurement trigger condition and a measurement frequency point.
Generally, in order to achieve the acquisition of parameters and the monitoring of the state of the terminal side, the network device needs to send measurement configuration information to a designated node, so that the terminal measures quality information of a cell where the terminal is located according to the measurement configuration information.
And S302, measuring the 5G service cell according to the measurement configuration message to obtain a measurement report.
The 5G serving cell is an area where the terminal can obtain a 5G network service, and is a cell divided from the whole 5G communication serving cell, and a 5G base station is arranged in the cell and is responsible for establishing wireless connection with the terminal in the cell, so that the 5G terminal can perform 5G communication in any cell in the 5G communication serving cell. The measurement report is a main judgment basis for a series of processes such as cell selection, cell reselection, radio bearer reconfiguration, handover, load control and balancing, power control and the like, the accuracy and timeliness of the measurement report have important influence on the performance of the communication system, and the measurement report comprises the 5G signal strength of a 5G serving cell.
Generally, a terminal measures quality information of a 5G serving cell according to a measurement configuration message sent by a network device, and reports the quality information to the network device; when the terminal is switched to a new 5G serving cell, the previous measurement of the terminal is no longer applicable, and the network device needs to instruct the terminal to perform new measurement according to the states of the new 5G serving cell and the neighboring cell, so as to implement management of the connection state mobility of the terminal. The measurement control of the network equipment to the terminal is mainly realized by sending measurement control information to the terminal, and after the terminal finishes measurement, a measurement report is generated and reported to the network equipment, so that the network equipment can acquire parameters at the terminal side and monitor the state. In the measurement process initiated by the network device, the period for reporting the measurement report is fixed.
S303, judging whether the 5G signal intensity is larger than or equal to a first signal intensity threshold value.
In this embodiment, the first signal strength threshold is a lower limit value of a stronger 5G signal set in the terminal.
Generally, after obtaining the 5G signal strength of the 5G serving cell where the terminal is located, it needs to determine whether the 5G signal strength is greater than or equal to a first signal strength threshold, and if the 5G signal strength is greater than or equal to the first signal strength threshold, it indicates that the 5G signal is better at this time, the terminal can smoothly transmit data through the 5G network; if the 5G signal strength is less than the first signal strength threshold, which indicates that the 5G signal is in the middle of the time, the terminal may transmit data through the 5G network, which may result in data loss.
And S304, if the 5G signal strength is greater than or equal to the first signal strength threshold value, establishing 5G data connection through the 5G serving cell.
In this embodiment, the first signal strength threshold is a lower limit value of a stronger 5G signal set in the terminal. The 5G data connection refers to a mode in which a terminal supporting 5G can perform 5G network communication.
Generally, if the 5G signal strength is greater than or equal to the first signal strength threshold, which indicates that the 5G signal is better at this time, the terminal can smoothly transmit data through the 5G network, so that a 5G data connection can be established through the 5G serving cell, and data can be transmitted through the 5G data connection.
S305, the target data is transmitted only through the 5G data connection.
The target data is information transmitted by a user through a data connection by using a terminal.
Generally, when the 5G signal strength is good, the effect of data transmission by a user through a 5G data connection by using a terminal is good, and good internet experience can be brought to the user only by selecting data transmission through the 5G data connection.
S306, if the 5G signal strength is smaller than the first signal strength threshold value, whether the 5G signal strength is smaller than the second signal strength threshold value is judged.
In the embodiment of the present application, the second signal strength threshold refers to an upper limit value of a weaker 5G signal set in the terminal, and when the actual 5G signal strength is smaller than the second signal strength threshold, it indicates that the 5G signal is the worst at this time, and the terminal transmits data through the 5G network, which may cause data loss; the first signal strength threshold is greater than the second signal strength threshold.
Generally, when it is determined that the 5G signal strength is smaller than the first signal strength threshold, it is further determined whether the 5G signal strength is smaller than the second signal strength threshold, and if the 5G signal strength is greater than or equal to the second signal strength threshold and smaller than the first signal strength threshold, it indicates that the 5G signal is moderate at this time, and a data loss phenomenon may occur when the terminal transmits data through the 5G network, so that it is necessary to transmit data through the 4G network at the same time to avoid the data loss phenomenon; if the 5G signal strength is smaller than the second signal strength threshold, it indicates that the 5G signal is poor at this time, and the terminal transmits data through the 5G network, which may result in data loss, so that the 5G network needs to be closed, and the 4G network with better signal strength is selected for data transmission.
And S307, if the 5G signal strength is smaller than the second signal strength threshold value, searching for a 4G serving cell, and measuring the 4G signal strength of the 4G serving cell.
The 4G service cell is an area where the terminal can obtain a 4G network service, and is a cell divided from the whole 4G communication service area, and a 4G base station is arranged in the cell and is responsible for establishing wireless connection with the terminal in the cell, so that the 4G terminal can perform 4G communication in any cell in the 4G communication service area.
Generally, when the 5G signal strength is smaller than the second signal strength threshold, it indicates that the 5G signal is poor, and if data loss occurs during data transmission using the 5G network, it is necessary to search for a 4G serving cell and measure the 4G signal strength of the searched 4G serving cell to find a 4G serving cell with better 4G signal strength.
And S308, when the 4G signal strength is greater than or equal to the third signal strength threshold value, establishing 4G data connection only through the 4G serving cell.
The threshold is also referred to as a threshold, and refers to a lowest value or a highest value that an effect can generate, and in this embodiment, the third signal strength threshold refers to a lower limit of a stronger 4G signal set in the terminal. The 4G data connection refers to a mode in which a 4G-capable terminal can perform 4G network communication.
Generally, when the 4G signal strength is greater than or equal to the third signal strength threshold, it indicates that the 4G signal is better at this time, the terminal can smoothly transmit data through the 4G network, and establish 4G data connection under the condition that the 5G signal strength is poorer and the 4G signal strength is better, and data transmission through the 4G data connection can ensure that data required to be transmitted by a user is not lost, so that the internet experience of the user is improved; when the 4G signal strength is smaller than the third signal strength threshold value, the terminal needs to determine the strength of the 4G signal strength and the 5G signal strength at the moment, and if the 4G signal strength is stronger than the 5G signal strength, 4G data connection is selected to be established; and if the 4G signal strength is weaker than the 5G signal strength, selecting to establish the 5G data connection.
S309, target data is transmitted only through the 4G data connection.
The target data is information transmitted by a user through a data connection by using a terminal.
Generally, when the 5G signal strength is poor and the 4G signal strength is good, the user has a good data transmission effect through the 4G data connection by using the terminal, and better internet experience can be brought to the user only by selecting to transmit data through the 4G data connection.
S310, if the 5G signal strength is smaller than the first signal strength threshold and greater than or equal to the second signal strength threshold, establishing a 5G data connection through the 5G serving cell.
Generally, when the 5G signal strength is smaller than the first signal strength threshold and greater than or equal to the second signal strength threshold, which indicates that the 5G signal strength is medium, the 5G data connection may be established through the 5G serving cell, but a 4G data connection also needs to be established, and at the same time, the user is ensured to be able to smoothly transmit data through the 4G data connection and the 5G data connection.
S311 searches for a plurality of 4G cells, and selects a cell with the highest 4G signal strength as a 4G serving cell.
Here, the 4G cell refers to an area covered by a 4G base station in a cellular mobile communication system. The 4G service cell is an area where a terminal can obtain 4G network service, is a cell divided from the whole 4G communication service area, can establish wireless connection with the terminal in the cell through a 4G base station in the cell, and supports the 4G terminal to carry out 4G communication in any cell in the 4G communication service area.
Generally, after establishing a 5G data connection, a 4G data connection needs to be further established, so that a plurality of 4G cells need to be searched, and a cell with the highest 4G signal strength is selected from the plurality of 4G cells as a 4G serving cell, so as to ensure that a good 4G network environment can be provided for the terminal.
S312, establish a 4G data connection through the 4G serving cell.
Here, the 4G data connection refers to a mode in which a 4G-capable terminal can perform 4G network communication.
Generally, after selecting a cell with the largest 4G signal strength as a 4G serving cell, the terminal establishes a 4G data connection through the 4G serving cell, so that the terminal can transmit data through the 4G data connection.
S313, a first channel quality of the 4G data connection is obtained, and a second signal quality of the 5G data connection is obtained.
The channel quality is a factor affecting the transmission performance of the network, and is affected by the channel capacity, the channel bandwidth, the signal-to-noise ratio, the bit error rate, and the like. The first channel quality refers to the channel quality of the 4G data connection and is used for measuring the transmission performance of the 4G data connection; the second channel quality refers to the channel quality of the 5G data connection, and is used for measuring the transmission performance of the 5G data connection.
And S314, determining a data distribution ratio according to the proportional relation between the first channel quality and the second channel quality.
The data distribution proportion refers to the proportion relation of data quantity transmitted through the 4G data connection and the 5G data connection respectively.
Generally, the 4G data connection and the 5G data connection have different maximum data volumes due to different channel qualities, a data allocation proportion can be determined according to a proportional relation between a first channel quality of the 4G data connection and a second channel quality of the 5G data connection, and data volumes transmitted through the 4G data connection and the 5G data connection are reasonably allocated according to target data to be transmitted, so that the target data can be transmitted quickly, and the channel utilization rate of the 4G data connection and the 5G data connection is improved.
For example, referring to the relationship correspondence table in table 1, the data allocation ratio of the 4G data connection and the 5G data connection is determined according to the proportional relationship between the first channel quality of the 4G data connection and the second channel quality of the 5G data connection, and since the 5G transmission rate is much higher than the 4G transmission rate, but the 5G transmission rate is also slowed down by the influence of the channel quality, the data allocation ratio of the data transmission through the 4G data connection and the 5G data connection can be determined according to the respective channel quality proportional relationship when the 4G/5G dual connection transmits data. Although the transmission rate of 5G will be affected by the channel quality, the overall transmission rate is higher than the transmission rate of 4G, so the data distribution ratio relationship of the 4G data connection and the 5G data connection is determined according to the ratio relationship of the first channel quality and the second channel quality, and according to the ratio relationship that the data transmitted by the 4G data connection is 20% of the total data and the data transmitted by the 5G data connection is 80% of the total data: when the ratio relation of the first channel quality and the second channel quality is 3:2, the data distribution ratio of the 4G data connection and the 5G data connection is 3: 8; when the proportional relation between the first channel quality and the second channel quality is 1:5, the data distribution proportion of the 4G data connection and the 5G data connection is 1: 20; when the proportional relation between the first channel quality and the second channel quality is 3:4, the data distribution proportion of the 4G data connection and the 5G data connection is 3: 16; when the ratio of the first channel quality to the second channel quality is 1:1, the data distribution ratio of the 4G data connection and the 5G data connection is 1: 4.
TABLE 1
And S315, transmitting the target data through the 4G data connection and the 5G data connection according to the data distribution ratio.
The target data is information transmitted by a user through a data connection by using a terminal.
Generally, after a 4G data connection and a 5G data connection are established at a terminal and a data distribution ratio is determined according to a proportional relation between a first channel quality of the 4G data connection and a second channel quality of the 5G data connection, target data which a user wants to transmit can be transmitted through the 4G data connection and the 5G data connection, so that a data transmission rate is improved, and better internet experience is brought to the user.
As can be seen from the above, in the data transmission method provided in this scheme, the terminal receives a measurement configuration message sent by the network device, measures the 5G serving cell according to the measurement configuration message to obtain a measurement report, where the measurement report includes a 5G signal strength of the 5G serving cell, determines whether the 5G signal strength is greater than or equal to a first signal strength threshold, and if the 5G signal strength is greater than or equal to the first signal strength threshold, establishes a 5G data connection through the 5G serving cell, and transmits the target data only through the 5G data connection; judging whether the 5G signal strength is smaller than a second signal strength threshold value or not, if the 5G signal strength is smaller than the second signal strength threshold value, searching a 4G service cell, and measuring the 4G signal strength of the 4G service cell; when the 4G signal strength is greater than or equal to the third signal strength threshold value, establishing 4G data connection only through the 4G serving cell, and transmitting target data only through the 4G data connection; if the 5G signal strength is smaller than the first signal strength threshold and larger than or equal to the second signal strength threshold, establishing 5G data connection through the 5G serving cell, searching a plurality of 4G cells, selecting the cell with the maximum 4G signal strength as the 4G serving cell, establishing 4G data connection through the 4G serving cell, acquiring first channel quality of the 4G data connection and second signal quality of the 5G data connection, determining a data distribution proportion according to the proportional relation between the first channel quality and the second channel quality, and transmitting target data through the 4G data connection and the 5G data connection according to the data distribution proportion. By the method, the terminal can select a mode of transmitting data through the 4G data connection and the 5G data connection or transmitting data only through the 4G data connection when the 5G signal is not good, so that the data required to be transmitted by a user is not easy to lose, and the internet surfing experience of the user is improved.
