The present application will now be described in further detail with reference to the accompanying drawings and specific examples.
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
The technical solutions described in the embodiments of the present application may be arbitrarily combined without any conflict.
In addition, in the embodiments of the present application, "first," "second," and the like are used to distinguish similar objects, and are not necessarily used to describe a particular order or sequence.
Fig. 1 shows a flowchart of an implementation of a data transmission method provided in an embodiment of the present application. As shown in fig. 1, the method includes:
s101: determining the service type and the first parameter of the current service of the first terminal; and the first parameter characterizes a time delay threshold corresponding to the service type.
Here, determining a service type and a first parameter of a current service of a first terminal, where the first parameter characterizes a delay threshold corresponding to the service type, where the current service refers to a data service that needs to be transmitted by the terminal, the service type may be divided according to a transmission direction of the data service, where the transmission direction includes uplink transmission and downlink transmission, the uplink transmission refers to that the terminal sends data to a network, the downlink refers to that the network sends data to the terminal, in practical application, the data transmission may occur between the terminal and a server, as shown in fig. 2, fig. 2 shows a data transmission flow diagram between the terminal and the server, and in fig. 2, the terminal sends data to an application server as uplink transmission, and the application server sends data to the terminal as downlink transmission. Data transmission may also occur between two terminals, such as performing a video call between two terminals, as shown in fig. 3, fig. 3 shows a schematic flow of data transmission between two terminals, and for terminal 1 in fig. 3, terminal 1 sends data to terminal 2 as uplink transmission, and terminal 2 sends data to terminal 1 as downlink transmission. The service type can be divided into the above service with the main behavior, the following service with the main behavior, and the service with both uplink and downlink according to the transmission direction of the data service, for example, the video service is the service with the main behavior, and the chat service is the service with both uplink and downlink. When data transmission is performed, a certain amount of data needs to be transmitted by the terminal through the wireless network, the data is called transmission delay, the first parameter is used for representing a delay threshold corresponding to the current service type, the transmission delay corresponding to the current service is required to be smaller than or equal to the delay threshold, as shown in fig. 4, fig. 4 shows delay thresholds corresponding to different service types, and the delay threshold can be customized by a user. In practical applications, the service may be divided into a low transmission delay service and a normal transmission delay service according to the size of the first parameter, where the low transmission delay service indicates that data transmission of the current service needs to be completed as soon as possible, for example, related services such as video playing, picture downloading, etc., and the normal transmission delay service may be other services than the low transmission delay service. In practical applications, when data transmission occurs between a terminal and a server, the transmission delay is mainly caused by the current network condition of the terminal, when data transmission occurs between the terminal and the terminal, the transmission delay is mainly caused by the respective network conditions of both communication terminals, and because the data transmission between the terminal and the terminal needs to pass through the respective wireless network, the transmission path side length is caused, so the transmission delay between the terminal and the terminal is generally larger than the transmission delay between the terminal and the server.
In an embodiment, as shown in fig. 5, the determining the service type and the first parameter of the current service of the first terminal includes:
s501: and determining the channel identification of the transmission channel of the current service of the first terminal.
Here, a channel identification of a transmission channel of the current service of the first terminal is determined, wherein the channel identification is used for distinguishing different transmission channels. When data transmission is performed, a corresponding transmission channel is required to be established for the current service, the data of the current service is transmitted through the transmission channel, in practical application, the transmission channels corresponding to different services are different, and in practical application, the channel identifier can be formed by a five-tuple identifier of a transmission layer and comprises a source end IP address, a source end port number, a destination end IP address, a destination end port number and a transmission protocol type. In practical applications, the channel identifier is extracted according to the transmitted data packet.
S502: determining an application program corresponding to the channel identifier in a first list; and the first list stores the corresponding relation between the channel identification and the application program.
Here, since there is a correlation between the channel identifier and the service, by the channel identifier, an application corresponding to the channel identifier can be determined in the first list, and the application corresponding to the channel identifier refers to an application that needs to perform the current service. In practical application, the first list stores the corresponding relation between different channel identifiers and application programs, and the corresponding application programs can be obtained by matching the extracted channel identifiers with the first list, and in practical application, the corresponding application programs can be determined by the application identifiers.
S503: determining the service type and the first parameter of the current service in a second list according to the determined application program; the second list stores the corresponding relation between the application program and the transmission requirement, wherein the transmission requirement comprises a service type and a first parameter.
Here, after determining the application program, the service type and the first parameter of the current service are determined through a second list, where the second list stores a correspondence between the application program and a transmission requirement, and the transmission requirement includes the service type and the first parameter. In practical application, the second list may include 6 sub-lists, which are an uplink transmission main low latency list, an uplink transmission main normal latency list, a downlink main low latency list, a downlink main normal latency list, an uplink downlink transmission low latency list, and an uplink downlink transmission normal latency list, and the service type and the first parameter are determined according to the sub-list where the application program is located. In practical application, the second list may be customized according to the user requirement, the terminal may provide a customization interface, and all applications currently installed by the terminal and possibly performing data transmission with the network are presented on the interface, and the transmission requirements corresponding to different application programs are determined by the user, for example, the user may determine the selected application program as a low-latency service. In practical applications, the second list may also be constructed based on user history data, for example, by determining an application program frequently used by the user as a low-latency service, thereby generating a low-latency service list.
In the above embodiment, the channel identifier of the transmission channel of the current service of the first terminal is determined, the application program corresponding to the channel identifier is determined in the first list, the first list stores the corresponding relationship between the channel identifier and the application program, the service type and the first parameter of the current service are determined in the second list according to the determined application program, and the second list stores the corresponding relationship between the application program and the transmission requirement, wherein the transmission requirement comprises the service type and the first parameter, so that the transmission requirements of different services can be determined according to the requirement of the user, and data transmission can be performed based on the transmission requirement meeting the customization of the user.
In an embodiment, the determining the service type and the first parameter of the current service of the first terminal includes:
under the condition that a first function of the first terminal is started, determining the service type and the first parameter of the current service of the first terminal; the first functional characterization allows the first terminal to perform cell switching according to the service type and the first parameter of the current service.
Here, when determining the service type and the first parameter of the current service of the first terminal, the state of the first function of the first terminal needs to be detected, the first function characterization allows the first terminal to perform cell switching according to the service type and the first parameter of the current service, and when the first function of the first terminal is closed, it is explained that the terminal does not grant the permission to perform cell switching according to the current service type and the first parameter, so that the determination of the service type and the first parameter of the current service of the first terminal is not needed. When the first function of the first terminal is started, the authority for granting the first terminal the cell handover according to the current service type and the first parameter is described, so that the service type and the first parameter of the current service of the first terminal need to be determined. In practical application, the first function may be turned on or turned off on the terminal interface, and the user may select to turn on or off the first function according to the requirement, or may set on or off the first function by means of a system debug command.
In the above embodiment, under the condition that the first function of the first terminal is turned on, the service type and the first parameter of the current service of the first terminal are removed, and the first function characterization allows the first terminal to perform cell switching according to the service type and the first parameter of the current service, so that the corresponding processing strategy of data transmission can be selected according to the state of the terminal, different data transmission strategies can be compatible, and the data transmission rate is improved.
S102: determining a first measurement; the first measurement result characterizes a transmission delay of a serving cell of the first terminal.
Here, a first measurement is determined, the first measurement characterizing a transmission delay of a serving cell of the first terminal. When the transmission delay of the serving cell of the first terminal is measured, the time required by the serving cell of the first terminal for transmitting data is substantially measured, and the time is divided into uplink transmission and downlink transmission when the data is transmitted, and the corresponding first measurement result can determine the delay corresponding to the uplink transmission and the delay corresponding to the downlink transmission. In practical applications, different services have different time delay requirements, for example, for video services, data transmission mainly uses downlink data, and more attention is paid to time delay corresponding to downlink transmission, for social information sending services, data transmission mainly uses uplink data and downlink data, and the time delay corresponding to uplink transmission and the time delay corresponding to downlink transmission need to be considered simultaneously, so when determining a first measurement result, the transmission direction in which time delay measurement needs to be performed can be determined according to the service type of the service, and thus time delay measurement can be performed in a targeted manner. In practical application, when determining the first measurement result, the transmission direction of the reverse delay measurement needs to be passed, the total amount of data to be transmitted required by the current service is estimated, when the total amount of data to be transmitted is greater than or equal to the set measurement data amount, the set measurement data amount is used for performing delay measurement to obtain the first measurement result, and when the total amount of data to be transmitted is less than the set measurement data amount, the total amount of data to be transmitted can be directly used for performing delay measurement to obtain the first measurement result.
S103: and under the condition that the first parameter is not matched with the first measurement result, determining a first target cell matched with the first parameter in a set cell library corresponding to the service type.
Here, after determining the first measurement result, if the first parameter does not match the first measurement result, it is indicated that the time for transmitting data in the serving cell of the first terminal cannot meet the data transmission requirement of the current service, and it is necessary to determine the first target cell matching the first parameter in the set cell library corresponding to the service type. In practical application, as shown in fig. 6, fig. 6 shows a schematic structural diagram of a set cell library, in the set cell library, the cells can be classified according to uplink and downlink directions, so that the set cell library is divided into an uplink main set cell library, a downlink main set cell library and an uplink and downlink combined set cell library, and further, the cells in the set cell library can be divided into a high-delay cell, a common-delay cell and a low-delay cell according to the delay information, wherein the high-delay cell is a cell with data transmission delay greater than a high-delay threshold, the common-delay cell is a cell with data transmission delay less than a Gao Shiyan threshold and greater than a low-delay threshold, and the low-delay cell is a cell with data transmission delay less than a low-delay threshold. In practical application, when the set cell library is constructed and the data transmission objects are terminals, for example, when data transmission is performed between the first terminal and the second terminal, the delay information and the position information of the cell of the second terminal are recorded in the serving cell accessed by the first terminal initiating measurement. The set Cell library also records the information of the Cell, including static information and dynamic information, wherein the static information refers to the identification information related to the Cell, does not change along with the position and time change of the terminal in the coverage area of the Cell, and includes a Cell communication system, cell operator information and frequency resource information, and takes an LTE communication system as an example, the radio access type (RAT, radio Access Type), mobile country code (MCC, mobile Country Code), mobile network number (MNC, mobile Network Codes), cell identification (CI, cell Identity), physical Cell identification (PCI, physical Cell Identifier), carrier splice number (EARFCN, E-UTRA Absolute Radio Frequency Channel Number) and BandWidth (BandWidth) of the Cell are required to be recorded. The dynamic information refers to signal strength information of a cell, which can change along with the change of the position and time of a terminal in the coverage area of the cell, and takes an LTE communication system as an example, reference signal received power (RSRP, reference Signal Receiving Power), LTE reference signal received quality (RSRQ, reference Signal Receiving Quality), and reference signal to noise ratio (RSSNR, reference Signal Signal to Noise Ratio) need to be recorded. The first terminal is configured to determine that the first target cell is a common delay cell or a high delay cell when the first measurement result indicates that the transmission delay of the serving cell of the first terminal is greater than the low delay threshold, and the transmission requirement of the current service of the first terminal cannot be met, so that the first target cell with the transmission delay meeting the low delay threshold needs to be found in a set cell library with the uplink transmission as a main component. In practical application, when the first parameter is matched with the first measurement result, it is indicated that the serving cell of the first terminal can meet the transmission requirement of the current service, and the cell currently accessed by the terminal does not need to be changed. In practical application, when a terminal has multiple home networks, for example, when the terminal accesses to mobile phone cards of two network operators, a first target cell is determined according to a set cell library corresponding to a service type of the home network of the terminal, so that a target cell with the lowest transmission delay can be selected, for example, a network condition of the home network corresponding to the terminal can be compared, the first target cell is determined in a set cell library corresponding to a service type with high network quality, as shown in fig. 7, fig. 7 shows a schematic diagram of data transmission under the condition that the terminal has multiple home networks, when the terminal currently uses a network of the operator 1 as a main network, the transmission delay will be increased due to poor network condition of the current operator 1, and when it is determined that the network quality of the current operator 2 is higher than that of the operator 1, the terminal is accessed to a cell of the operator 2 for data transmission, so that the transmission rate can be improved. In practical application, when determining the first target cell, the load of the current cell needs to be considered, the transmission delay of the cell is also related to the cell load, and the cell load includes the number of terminals accessed by the current cell and the number of terminals performing data transmission. For example, for a subway station, when the traffic is high, the cell cannot provide high-rate data transmission for each terminal, and when the traffic is low, the data transmission requirement is reduced, and the cell can have relatively sufficient resources to provide high-rate data transmission for the accessed terminal.
In an embodiment, as shown in fig. 8, in a case where the first parameter does not match the first measurement result, determining, in a set cell library corresponding to the service type, a first target cell matching the first parameter includes:
s801: determining a first set cell library from at least two set cell libraries corresponding to the service type according to a first position of the first terminal; the first set cell library characterizes the set cell library closest to the first position in at least two set cell libraries corresponding to the service type.
Here, the first set cell pool is determined according to a first location where the first terminal is located. In practical application, network deployment corresponding to different positions is different, and effective coverage area exists in the cell, and when the terminal is out of the coverage area of the cell, the terminal cannot access the cell, so that the first set cell library needs to be determined according to the position of the terminal. In practical application, according to a first position where a first terminal is located, determining at least two set cell libraries corresponding to a service type located near the first position, and determining a set cell library closest to the first position in the at least two set cell libraries corresponding to the service type as the first set cell library, so that the set cell library can be matched to the corresponding set cell library according to the position where the terminal is located.
S802: determining a second measurement result corresponding to a first candidate cell in the first set cell library; the second measurement characterizes a transmission delay of the first candidate cell.
Here, a second measurement result corresponding to the first candidate cell in the first set cell library is determined, where the second measurement result characterizes a transmission delay of the first candidate cell, in practical application, one first candidate cell may be randomly selected in the first set cell library, so as to determine a second measurement result corresponding to the first candidate cell, where the second measurement result can be used as a basis for determining the first target cell.
S803: and determining the first candidate cell as the first target cell in the case that the second measurement result is matched with the first parameter.
Here, the second measurement result is compared with the first parameter, and when the second measurement result matches with the first parameter, it is explained that the second measurement result in the first candidate cell is smaller than or equal to the first parameter, the requirement of data transmission is satisfied, and the first candidate cell is determined as the first target cell.
S804: determining the first target cell in at least one second candidate cell if the second measurement does not match the first parameter; the second candidate cell is other cells except the first candidate cell in the first set cell library.
Here, in the case that the second measurement result does not match the first parameter, it is explained that the first candidate cell cannot meet the requirement of data transmission, and the first target cell needs to be determined in at least one second candidate cell, where the second candidate cell refers to other cells than the first candidate cell in the first set cell library. In practical application, the cell identifier of the first candidate cell may be recorded, so that the second candidate cell may be determined in the first setting database, and the transmission delay corresponding to the second candidate cell may be determined, so that the first target cell may be determined in the second candidate cell.
In an embodiment, as shown in fig. 9, the determining, in the set cell library corresponding to the service type, a first target cell that matches the first parameter includes:
s901: determining a second set cell library when the terminal is in a mobile state; wherein the terminal moves from the first position to the second position; the second set cell library characterizes a set cell library closest to the second position; .
