Detailed Description
The technical scheme of the embodiment of the invention is suitable for an application scene for controlling data transmission between the server and the mobile terminal. By adopting the technical scheme of the embodiment of the invention, the downlink data transmission of each terminal can be reasonably regulated and controlled according to the priority of each terminal when the downlink data transmission is congested.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a data transmission control method, which is applied to a server and is shown in figure 1, and the method comprises the following steps:
when data transmission is performed with a mobile terminal, if channel congestion is detected, the following processing is performed:
s101, respectively determining the priority of the mobile terminal and the priorities of other mobile terminals which are positioned under the same base station with the mobile terminal and are carrying out data transmission with the server;
specifically, when the server knows that channel congestion occurs when data transmission is performed with the mobile terminal, the server first determines the priority of the mobile terminal and the priority of other mobile terminals which are under the same base station with the mobile terminal and are performing data transmission with the server. And the server respectively determines the base station connected with each mobile terminal through the registered base station ID sent by the mobile terminal.
S102, selecting a set number of mobile terminals with lower priority than the mobile terminals from the other mobile terminals according to the priority of the mobile terminals and the priorities of the other mobile terminals;
specifically, after determining the priorities of other mobile terminals under the same base station that are performing data transmission with the server, the embodiment of the present invention selects a set number of mobile terminals with lower priorities than the mobile terminals from the other mobile terminals. The number of the above-mentioned components may be any positive integer.
S103, reducing the data specification of the data transmitted with the selected mobile terminal.
Specifically, the data specification includes parameter specifications such as a frame rate, a code rate, or a resolution of the data. The data specification of the data is reduced, and the bandwidth occupied by data transmission can be reduced. Therefore, after a set number of mobile terminals are selected from other mobile terminals, the embodiment of the present invention reduces the data specification of the data transmitted with the selected mobile terminals, so as to make the data transmission of the selected mobile terminals occupy less bandwidth, thereby freeing up bandwidth for the mobile terminal with higher priority and making the data transmission of the mobile terminal with higher priority more smooth.
It should be noted that, when the server detects whether channel congestion occurs during data transmission with the mobile terminal, the server may actively detect the channel congestion, or may set the channel congestion to be detected by the mobile terminal and send a detection result to the server, so that the server determines whether channel congestion occurs. In the embodiment of the invention, whether the channel is congested is detected by the mobile terminal, if the channel is congested, the channel congestion warning information is sent to the server, and when the server receives the channel congestion warning information, the channel congestion is detected.
As can be seen from the above description, in the technical solution of the embodiment of the present invention, when the data transmission of the mobile terminal is congested, the server reduces the data specification of the mobile terminal with a lower priority than the mobile terminal, so as to ensure smooth data transmission of the mobile terminal, that is, when a bandwidth bottleneck occurs in the data transmission, the service of the mobile terminal with a high priority is ensured to be normally performed.
The embodiment of the invention also discloses a data transmission control method applied to a mobile terminal, which corresponds to the data transmission control method applied to the server shown in fig. 1, and the data transmission control method is shown in fig. 2, and the method comprises the following steps:
when data transmission is performed with the server, step S201 is executed to detect whether a data transmission channel is congested;
specifically, a timestamp is carried on a data packet received by the mobile terminal, and after the timestamp is read, the real-time bandwidth can be calculated according to the timestamp. When the current bandwidth is found to be smaller than the bandwidth required by the data packet, which results in that the transmission time of the data packet exceeds the set length, the mobile terminal can determine that the data transmission channel is congested.
When the data transmission channel is congested, executing step S202, and sending channel congestion warning information to the server, so that the server can perform data transmission control processing according to the channel congestion warning information;
specifically, when the mobile terminal finds that the data transmission channel is congested, the mobile terminal server sends channel congestion warning information. The channel congestion warning information is used for informing the server that channel congestion occurs during data transmission, so that the server controls and processes data transmission from the source of the data transmission.
By adopting the technical scheme of the embodiment of the invention, the mobile terminal can actively send the warning information to the server when detecting the data transmission congestion and inform the server of carrying out data transmission control processing, thereby being beneficial to processing the channel congestion in time.
It can be understood that the data transmission control methods shown in fig. 1 and fig. 2 are data transmission control methods according to embodiments of the present invention, which are described by taking a server and a mobile terminal as main execution objects, respectively. In fact, when the technical solution provided by the embodiment of the present invention is actually implemented, the mobile terminal and the server need to cooperate with each other to implement the data transmission control method. The following describes in detail a specific implementation process of the data transmission control method shown in fig. 1 and 2, which is executed by the mobile terminal and the server together in an actual operation process.
Fig. 3 shows a specific process of the data transmission control method shown in fig. 1 and 2. Referring to fig. 3, a data transmission method provided in the embodiment of the present invention specifically includes:
s301, the server sets priority for each served mobile terminal respectively;
specifically, according to the technical scheme of the embodiment of the invention, the priority of each mobile terminal is taken as a basis, when the data transmission with the mobile terminal meets the bandwidth bottleneck, the data transmission with each mobile terminal is controlled and processed, and the data transmission of the mobile terminal with higher priority is preferentially ensured. Therefore, the server needs to clarify the priority of each served mobile terminal so as to control the data transmission of each mobile terminal according to the priority of each mobile terminal performing data transmission when bandwidth bottleneck occurs. Each of the mobile terminals includes each of the mobile terminals under all the base stations to which the server is connected.
The server may set the priority for each mobile terminal based on the identification code of the mobile terminal, or may set the priority for different types of mobile terminals based on the type of the mobile terminal.
S302, the mobile terminal sends login request information to a server;
specifically, when a mobile terminal needs to request data from a server, it needs to log in the server first, and at this time, the mobile terminal sends login request information to a server located at an upper layer of the base station through the base station network. The login request information carries identification information of the base station.
Correspondingly, the server executes the step S303 and receives a login request sent by the mobile terminal;
then executing step S304, and carrying out authentication processing on the mobile terminal according to the login request;
specifically, after receiving a login request sent by a mobile terminal, a server extracts mobile terminal identification information from the received login request, authenticates the mobile terminal according to the identification information of the mobile terminal, and judges whether the mobile terminal has authority to log in the server and request data.
When the mobile terminal passes the authentication, the server executes step S305 to allow the mobile terminal to log in the server.
Specifically, when the server verifies that the mobile terminal sending the login request passes the authentication, the mobile terminal is allowed to log in the server, and meanwhile, login-allowing information is fed back to the mobile terminal.
When the server allows the login, the mobile terminal performs step S306, logs in the server, and transmits a registered base station ID to the server.
Specifically, after receiving the registration permission information fed back by the server, the mobile terminal registers in the server and transmits the registered base station ID to the registered server. The registered base station ID refers to a base station ID to which the mobile terminal is connected. It will be appreciated that the registered base station IDs of mobile terminals connected to the same base station are the same, whereas the registered base station IDs of mobile terminals connected to different base stations are different.
At this point, the mobile terminal and the server complete a link connection, and the mobile terminal can request data from the server through the link. When a mobile terminal requests data from a server, data request information is sent to the server, and the data request information carries relevant information of the requested data. After receiving the data request information sent by the mobile terminal, the server determines the data requested by the mobile terminal, then searches the data from the memory and transmits the data to the mobile terminal. The server may specifically transmit data to the mobile terminal in a Real-time Transport Protocol (RTP) fragmentation manner.
When the server transmits data to the mobile terminal, the mobile terminal receives the data transmitted by the server and executes step 307 to detect whether the data transmission channel is congested;
specifically, a timestamp is carried on a data packet received by the mobile terminal, and after the timestamp is read, the real-time bandwidth can be calculated according to the timestamp. When the current bandwidth is found to be smaller than the bandwidth required by the data packet, which results in that the transmission time of the data packet exceeds the set length, the mobile terminal may determine that the data transmission channel sends congestion.
When the data transmission channel is congested, the mobile terminal executes step S308 to send channel congestion warning information to the server, so that the server can perform data transmission control processing according to the channel congestion warning information.
Specifically, when the mobile terminal finds that the data transmission channel is congested, the mobile terminal sends channel congestion warning information to the server. The channel congestion warning information is used for informing the server that channel congestion occurs during data transmission, so that the server controls and processes data transmission from a data transmission source.
Correspondingly, when the server receives the channel congestion warning information sent by the mobile terminal, the following processing is executed:
s309, respectively determining the priority of the mobile terminal and the priorities of other mobile terminals which are under the same base station with the mobile terminal and are carrying out data transmission with the server;
specifically, when the server knows that channel congestion occurs when data transmission is performed with the mobile terminal, the server first determines the priority of the mobile terminal and the priority of other mobile terminals which are under the same base station with the mobile terminal and are performing data transmission with the server. And the server respectively determines the base station connected with each mobile terminal through the registered base station ID sent by the mobile terminal.
In step S301, the server has set a priority for each mobile terminal, so that, after the server confirms other mobile terminals that are under the same base station as the mobile terminal and are performing data transmission with the server, the server may query the priority set for each mobile terminal in step S301 according to the identification information of each mobile terminal, and determine the priorities of the mobile terminal and other mobile terminals performing data transmission simultaneously with the mobile terminal.
Optionally, in step S309, after determining that the mobile terminal is located in the same base station as the mobile terminal and is performing data transmission with the server, the embodiment of the present invention may further set priorities for the mobile terminal and the other mobile terminals, respectively. That is, the embodiment of the present invention may omit the process described in step S301, and in the process described in step S309, the priorities of all the mobile terminals in data transmission in the same base station as the mobile terminal are temporarily determined. Compared with the method that the priority is set for each mobile terminal in the step S301, the method has the advantages that the workload is small, the priority is set more pertinently, and the method is suitable for real-time change of the priority of the mobile terminal.
S310, selecting a set number of mobile terminals with lower priority than the mobile terminal from the other mobile terminals according to the priority of the mobile terminal and the priorities of the other mobile terminals;
specifically, after determining the priorities of other mobile terminals under the same base station that are performing data transmission with the server, the embodiment of the present invention selects a set number of mobile terminals with lower priorities than the mobile terminals from the other mobile terminals. The number of the above-mentioned components may be any positive integer.
The server performs step S311 on the selected mobile terminal to reduce the data specification of the data transmitted with the selected mobile terminal.
Specifically, the data specification includes parameter specifications such as a frame rate, a code rate, or a resolution of the data. The data specification of the data is reduced, and the bandwidth occupied by data transmission can be reduced. Therefore, after a set number of mobile terminals are selected from other mobile terminals, the embodiment of the present invention reduces the data specification of the data transmitted with the selected mobile terminals, so as to make the data transmission of the selected mobile terminals occupy less bandwidth, thereby freeing up bandwidth for the mobile terminal with higher priority and making the data transmission of the mobile terminal with higher priority more smooth.
If there is no mobile terminal with a lower priority than the mobile terminal among the other mobile terminals, step S312 is executed to reduce the data size of the data transmitted with the mobile terminal.
Specifically, if the mobile terminal is the mobile terminal with the lowest priority among the mobile terminals which are under the base station where the mobile terminal is located and are performing data transmission with the server, that is, there is no mobile terminal with a lower priority than the mobile terminal, the embodiment of the present invention reduces the data specification of the data transmitted with the mobile terminal, so as to make the data transmission from the server to the mobile terminal more smooth.
