Background
At present, in order to consider both the traffic consumption of the video playing terminal and the quality of service of the playing data, the downloading strategy is generally adopted: the video playing terminal (hereinafter referred to as terminal) sets an upper limit value of the buffering time, such as 180 seconds. The buffer is used to download the data not played by the user as the buffer data in advance. When the caching time of the cached data reaches the upper limit value of the caching time, stopping downloading the cached data after caching is finished, and playing the cached data; otherwise, if the cache time is less than the lower limit value of the cache time, for example, 90 seconds, the cache data is continuously downloaded.
With the advent of high-speed moving vehicles such as high-speed rails, more and more users using terminals need to be in high-speed moving vehicles for communication, that is, in a high-speed mobile communication environment for user communication. Communication signals of a terminal in a high-speed mobile communication environment are rapidly switched between two or more base stations. Also, due to the variation of the available network types, the terminal may use different types of networks in different network environments (e.g., Enhanced Data Rate for GSM Evolution, EDGE for short), General Packet Radio Service (GPRS for short).
Due to the switching of the communication between the terminal and the plurality of base stations and the difference of different network types, etc., the terminal may be in a high-speed mobile communication environment and may be intermittent when downloading the cache data, and the cache data may not be downloaded in time. Therefore, when the terminal plays the video, once the downloaded cache data is played, the new cache video cannot be downloaded in time due to the network, and the video is jammed during playing.

Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Aiming at the problems that once the downloaded cache data is played when a terminal plays a video, a new cache video cannot be downloaded in time due to network reasons and the video is jammed during playing in the prior art, the embodiment of the invention provides a data transmission method and a data transmission device, wherein a server receives a user request sent by the terminal, and the user request carries a high-speed mobile communication identifier; and the server adjusts the data downloading mode of the terminal to a preset downloading mode.
Therefore, the server can adjust the data downloading mode of the terminal to the preset downloading mode according to the high-speed mobile communication identification in the user request based on the received user request. Therefore, the server can communicate with the terminal in a high-speed mobile communication environment, and the data downloading mode of the terminal is adjusted to the preset downloading mode, so that the terminal can download data quickly according to the preset downloading mode set by the preset server under the condition that a network is available, the data volume downloaded by the terminal is increased, the playing time of the downloaded data volume is prolonged, the times of pause during playing of the data are reduced, and the user experience effect is improved.
First, a data transmission method provided in an embodiment of the present invention is described below.
The data transmission method provided by the embodiment of the invention is applied to a User Equipment (UE for short). The UE may further be, but is not limited to: desktop computers, portable computers, terminals, servers, schedulers, and the like. Any UE that can implement the data transmission method in the embodiment of the present invention belongs to the protection scope of the embodiment of the present invention, and is not limited herein. Further, the data transmission method is also applied to a terminal on the UE, such as a Personal Computer (PC) or a terminal. The terminal may be, but is not limited to, a video playing terminal, and is not limited herein.
In a first aspect, to improve a user experience effect, which is described from the perspective of a server, an embodiment of the present invention provides a data transmission method, which, as shown in fig. 1, may include the following steps:
and step 110, the server receives a user request sent by the terminal, wherein the user request carries the high-speed mobile communication identifier. And the server establishes communication connection with the terminal.
The server cannot provide a certain download speed for the terminal due to the limitation of the quality of the signal, and only provides a better download channel for the terminal as much as possible. Wherein, the server may be but not limited to: the server directly establishes communication connection with the terminal, so that the server can receive a user request and directly adjust the data downloading mode of the terminal to the preset downloading mode.
The server may be, but is not limited to: the method comprises the steps that a user requests to allocate a high-priority network data center (IDC) node, the high-priority IDC node is determined through available bandwidth resources of IDC and IDC load, so that the high-priority IDC node responds to request data corresponding to the user request, and the terminal sends the user request to a scheduler. The dispatcher dispatches the server according to the high-speed mobile communication identifier in the user request, and then the server establishes communication connection with the terminal, so that the server is used for adjusting the data downloading mode of the terminal to the preset downloading mode.
The user request is used for requesting the server to improve the terminal data downloading speed. Because the terminal data downloading speed can be influenced by many factors, although the server can try to improve the terminal downloading speed, if no signal or poor signal exists, the terminal data downloading speed is still very limited, so the embodiment of the invention only needs to download as much as possible when the signal is available, so as to make up for the situation that the downloading is very slow or can not be carried out when the signal is poor. And, the high-speed mobile communication identifier carried in the user request can be used for identifying the high-speed mobile communication environment in which the terminal is located. The request identifier may be, but is not limited to, a character and/or a number, and for example, the identifier is a character of a "high-speed mode", and as long as the high-speed mobile communication identifier can identify a high-speed mobile communication environment in which the terminal is located, all of the protection scope of the embodiments of the present invention is included, and no example is given here.
The high-speed mobile communication environment may be an environment in which a communication signal of the terminal is rapidly switched between two or more base stations twice or more and a moving speed of the high-speed mobile device is greater than a preset speed. This preset speed can be set according to the needs of the industry. By way of example and not limitation, the predetermined speed may be 100 km/hr, and the moving speed greater than the predetermined speed may be greater than 100 km/hr. Further, the preset speed may be 200 km/h, and the preset speed may be 300 km/h. By way of example, but not limitation, the high speed moving tool is a high-speed rail in operation. Therefore, the user experience effect can be improved under the high-speed mobile communication environment.
In this step 110, the user request may be received directly from the terminal. Therefore, the server can directly communicate with the terminal conveniently, the terminal sends the user request and the server receives the user request under the condition that the terminal is in a high-speed mobile communication environment. The receiving pattern of the user request in this step 110 may also be forwarded by the scheduler. The scheduler receives the user request and schedules the server capable of improving the data downloading speed of the terminal by measuring the service indexes of each server based on the user request. The dispatcher forwards the received user request to the server, and the server receives the user request, so that the requirements of the terminal can be met, and the use of other servers can not be influenced.
The embodiment of the invention can pre-define the mode capable of identifying the user request, such as a high-speed mobile communication identifier, among the server, the scheduler and the terminal. The specific convention is further explained as follows:
prior to the above step 110, the method further comprises: in step 101, a server receives a user request.
And step 102, judging whether the user request carries a high-speed mobile communication identifier.
The step 102 implementation process is as follows: the server analyzes the received user request and determines each key value pair of a Uniform Resource Locator (URL) of the user request; the server detects whether each key value pair of the user request URL has a 'high-speed rail mode' character; if each key value pair of the URL requested by the user has a character of 'high-speed rail mode', the server determines that the user request carries a high-speed mobile communication identifier.
And 103, if the user request is judged to carry the high-speed mobile communication identifier, the server adjusts the data downloading mode of the terminal to a preset downloading mode.
And step 104, judging that the user request does not carry the high-speed mobile communication identifier, and directly responding to the user request by the server, wherein the user request does not carry the high-speed mobile communication identifier, which indicates that the user request is used for requesting terminal data under the condition that the terminal is in a non-high-speed mobile communication environment. Here, the non-high speed mobile communication environment refers to a communication environment other than the high speed mobile communication environment, that is, a normal communication environment of the terminal. Here, the response process of the user request may be a user request that the server returns to the terminal according to the user request.
The user request in this step 104 does not carry the high speed mobile communication identifier, but is not limited to this: and if the user request is judged to carry no high-speed mobile communication identification, or if the user request is judged to contain other request identifications.
In the embodiment of the invention, the server can process the user request carrying the high-speed mobile communication identification and can also process the user request not carrying the high-speed mobile communication identification; and the server can communicate with the terminal in a high-speed mobile communication environment, the data downloading mode of the terminal is adjusted to the preset downloading mode, the terminal can quickly download the terminal data according to the preset downloading mode set by the preset server under the condition that a network is available, and the data volume downloaded by the terminal data is increased, so that the playing time of the downloaded data volume is prolonged, the times of jamming and pause during playing of the data are reduced, and the user experience effect is improved.
And step 120, the server adjusts the data downloading mode of the terminal to a preset downloading mode.
The preset download mode may include, but is not limited to, one of the following: the server increases a mode for providing the terminal with the data downloading speed and a normal mode for providing the terminal with the data downloading speed. Since the high-speed mobile communication identifier corresponds to the preset download mode, that is, the server and the terminal can be agreed in advance, and the server can adjust the data download mode of the terminal to the preset download mode based on the user request when acquiring the high-speed mobile communication identifier.
The normal mode is also normal download. The terminal is in a non-high speed mobile communication environment and sends a user request capable of responding to the request data to the server. Here, the communication process in which the terminal and the server are in the non-high-speed mobile communication environment is a communication process in a normal mode.
In order to prioritize the server to adjust the data download mode of the terminal to the preset download mode, this step 120 may adopt at least one of the following possible implementation manners, but is not limited to this:
in a possible implementation manner, the server increases the priority of the data downloading speed of the terminal, and the server reduces the speed limit of the data downloading speed of the terminal. Generally, because the resource of the server is limited, and the bandwidth resource available for downloading resource allocation is limited, the server may limit the data downloading speed of the terminal, i.e. the speed limit. Here, reducing the speed limit for the data download speed of the terminal is equivalent to increasing the data download speed of the terminal, so that the server increases the data amount of data download for the terminal.
In the foregoing possible implementation manners, further, but not limited to: the server improves the priority of the data downloading speed of the terminal; the server limits or reduces the data downloading speed provided for the preset terminal, and the server reduces the speed limit of the data downloading speed of the terminal, wherein the preset terminal is a preset terminal in other terminals except the terminal. Because the resource of the server is limited, the bandwidth resource available for downloading resource allocation is limited, therefore, in order to reduce the speed limit of the data downloading speed of the terminal, the server can limit/reduce the data downloading speed provided by the preset terminal, thereby ensuring that the server improves the data downloading speed of the terminal. The preset terminal may be determined according to the importance level. Compared with the user request of the terminal, the distinguished data importance level of the preset terminal is lower.
In another possible implementation manner, the server increases the priority of the data downloading speed of the terminal; the server removes the speed limit for the data download speed of the terminal. Therefore, under the condition of removing the speed limit, the server can make the terminal download data as much as possible, and the server increases the data downloading speed of the terminal.
In the possible implementation manners, there are various manners for the server to increase the priority of the data download speed of the terminal, and the server directly allocates the priority for processing the user request to be the highest priority, so that the user request can be processed in time. For another example, the server allocates a first priority to the user request, where the first priority is a priority for processing the user request and is higher than a priority for processing the user request of the preset terminal; according to the first priority, the server increases the speed of providing data download for the terminal. This first priority is set according to the needs of the industry. The first priority may be determined in a manner including, but not limited to: and weighing the importance level of the user request of the preset terminal and the importance level of the user request of the terminal to determine a first priority. Therefore, the server can be ensured to provide the data downloading speed for the terminal in time, and the operation of the preset terminal is not influenced.
In the embodiment of the invention, the server can adjust the data downloading mode of the terminal to the preset downloading mode according to the high-speed mobile communication identification in the user request based on the received user request. Therefore, the server can communicate with the terminal in a high-speed mobile communication environment, and the data downloading mode of the terminal is adjusted to the preset downloading mode, so that the terminal can quickly download the terminal data according to the preset downloading mode set by the preset server under the condition that a network is available, the data volume downloaded by the terminal data is increased, the playing time of the downloaded data volume is prolonged, the times of jamming during playing of the data are reduced, and the user experience effect is improved.
In a second aspect, since the data downloading speed of the terminal may be affected by many factors, although the server may try to increase the downloading speed of the terminal, if there is no signal or a signal is not good, the data downloading speed of the terminal is still very limited, so that the data is downloaded as much as possible only when the signal is available to make up for the situation that the downloading is slow or impossible when the signal is not good, which is explained from the terminal, an embodiment of the present invention provides a data transmission method, as shown in fig. 2, which may include the following steps:
Wherein, the high-speed mobile communication environment in the step 210 is the same as the limited content of the high-speed mobile communication environment in the step 110; in this step 210, the user request may include the high speed mobile communication identifier that is the same as the high speed mobile communication identifier limitation content in the step 102, which can achieve the same beneficial effect and is not described herein again.
In this step 210, the terminal may send a user request to different destinations according to the service requirement, further including: the provisioning server may refer to, but is not limited to: the terminal sends a user request to the server which directly establishes the communication connection with the terminal, so that the preset server can be directly requested to adjust the data downloading mode of the terminal to the preset downloading mode.
Or, the preset server allocates an Internet Data Center (IDC) node with a high priority to the user request, the IDC node with the high priority is determined by the available bandwidth resource of the IDC and the load of the IDC, so that the IDC node with the high priority responds to the request data corresponding to the user request, and the terminal sends the user request to the scheduler. And scheduling a preset server by the scheduler according to the high-speed mobile communication identifier in the user request, and then establishing communication connection between the preset server and the terminal so as to finish adjusting the data downloading mode of the terminal to the preset downloading mode by using the preset server.
In addition, in order to be able to automatically send the user request, this step 210 may adopt at least one of the following possible implementations, but is not limited to this:
in a possible implementation manner, the terminal is in the process of playing the video online, and if the terminal is detected to be in the high-speed mobile communication environment, the user request is triggered and sent based on the started initiating switch of the user request.
For the possible implementation manners, the triggering manner for the terminal to send the user request further includes: in case that the terminal is in a high-speed mobile communication environment, the user request is actively transmitted. This actively detects the environment in which the terminal is located and the terminal actively sends the user request. Therefore, the operation steps of the user can be reduced, and the user experience is improved. Any manner of actively sending the user request falls within the scope of the embodiments of the present invention. One way is illustrated below, but not limited to:
step 1, if detecting that the terminal is in a high-speed mobile communication environment, starting an initiating switch requested by a user by the terminal; and step 2, triggering and sending the user request by the terminal based on the started initiating switch of the user request.
Wherein the initiating switch may be any button capable of triggering the sending of a user request. For convenience of user operation, an initiation switch may be displayed on the terminal. Illustratively, the initiation switch may be, but is not limited to, an icon displayed on the terminal. This icon lights up to indicate that the user requested the initiating switch to be turned on; this picture is darkened to indicate that the user requested the initiate switch not to be turned on. Further, this icon may be, but is not limited to being, in the area of the drop down menu icon of the terminal. This is by way of example only and not by way of limitation.
In addition to the switch capable of automatically sending the user request, in order to conform to the use habit of the user and improve the experience effect of the user, for the possible implementation manners, the triggering manner for the terminal to send the user request further includes:
step 1, a terminal is in the process of playing a video on line, and if the terminal is detected to be in a high-speed mobile communication environment, a starting operation instruction of an initiating switch is received; and step 2, the terminal triggers and sends a user request based on the opening operation instruction.
For example, the initiating switch may be, but is not limited to, an option added on a display interface of the terminal, in which a selection box of whether the "high-speed rail mode" is enabled is displayed.
When the above options are used specifically, in the first time, the previous preset time or each use process, the display content of the options further includes: the interpretation of this option by the terminal, i.e. "high-speed mode", enables accelerated downloading of video data, reduces the stutter, and, if this mode is turned on, accelerates the consumption of traffic. The preset times can be determined according to the requirements of users. Therefore, the user can know the used high-speed rail mode, and can determine whether to execute the starting operation instruction according to the requirement of the user and select whether to start the starting switch, so that the interactivity between the terminal and the user is improved. And on the premise that the user can accept the flow overhead caused by downloading the terminal data in advance, the experience effect of the user is improved.
In addition to statically adding a "high-speed rail mode" button on a terminal or a display interface of the terminal, since a user may not turn on an initiating switch requested by the user in time, and user experience may be affected, in order to solve this problem, a specific implementation process of the terminal receiving an operation instruction for turning on the initiating switch in step 1 is as follows:
firstly, a terminal is in the process of playing a video on line, and if the terminal is detected to be in a high-speed mobile communication environment, a reminding instruction is sent, wherein the reminding instruction is used for reminding the starting of an initiating switch; and secondly, the terminal receives a starting operation instruction returned by aiming at the reminding instruction.
The reminding mode of the reminding instruction can be any mode which can enable the terminal to receive feedback aiming at the reminding. The feedback may be, for example and without limitation, a returned start operation command, or a rejection of the start operation command. The reminding mode of the reminding instruction is exemplary and not limited to: and displaying a reminding mode of characters and a reminding mode of pictures. Illustratively, the reminding instruction is to remind the user to open the high-speed rail mode in a pop-up window mode.
The above-mentioned two or more times of reminding instructions may be that under the condition that the initiating switch is not turned on, the reminding duration is preset at intervals, and the terminal sends two or more times of reminding instructions until receiving the feedback aiming at the reminding; or the terminal sends a reminding instruction once when the terminal is used. The preset reminding duration can be set by default at the terminal or set according to the needs of the user.
In order to dynamically detect whether the terminal is in the high-speed mobile communication environment, step 210 may send the user request to the preset server by using any one of the following implementations:
referring to fig. 3 in conjunction with fig. 2, in one implementation, in step 201, the terminal acquires the geographic location of the terminal by using a positioning system. The Positioning System may be a Global Positioning System (GPS) module, so that the terminal can monitor whether the geographic location of the terminal is in the location of the high-speed mobile communication environment in real time, and the terminal can prompt the user to start the high-speed mode in a pop-up window manner.
the high speed mobile communication environment may refer to an environment in which a communication signal of the terminal is rapidly switched between two or more base stations twice or more and a moving speed of the high speed moving means is greater than a preset speed. Illustratively, the location of the high speed mobile communication environment is a high-speed rail along-line location that is not a station. Here, not by way of example, any environment capable of implementing high-speed mobile communication that meets the requirements of the embodiments of the present invention falls within the scope of the embodiments of the present invention.
In order to dynamically detect whether the terminal is in the high-speed mobile communication environment, step 210 may send the user request to the preset server by using any one of the following implementations:
referring to fig. 4 in combination with fig. 2, in another implementation manner, in step 204, the terminal obtains the network disconnection times, where the network disconnection times are network disconnection times for the terminal to communicate with a preset server using a cellular network.
The number of network disconnections satisfying the conditions of the high-speed mobile communication environment may be, but is not limited to: the network disconnection times are greater than a network disconnection time threshold, and the network disconnection time threshold can be set according to user requirements. The judgment mode of the network disconnection times or the connection times can be judged according to the speed of downloading the cache data by the terminal. Any condition that the network disconnection times can satisfy the high-speed mobile communication environment belongs to the protection scope of the embodiment of the invention, and no example is given here. For example, the preset time period may be set according to the user requirement. The terminal can count the network disconnection times of the terminal and the preset server for communication by using the cellular network within the preset time length, and set a network disconnection time threshold, so that when the network disconnection times exceed the network disconnection time threshold, the terminal can remind a user to start a high-speed railway mode in a pop-up window mode.
And step 206, the terminal determines that the network disconnection times do not meet the conditions of the high-speed mobile communication environment, and when the terminal detects that the terminal is not in the high-speed mobile communication environment, the terminal sends a user request without carrying a high-speed mobile communication identifier to a preset server. Thus, by using the number of network disconnections, the user request of the terminal can be determined.
And step 220, when the terminal detects that the current communication network is available, downloading data according to a preset downloading mode set by a preset server. The available current communication network means that the current communication network can meet the data downloading requirement.
The implementation flow of the embodiment of the invention is exemplified as follows:
firstly, when a high-speed rail mode is started, a terminal starts a peer-to-peer (P2P for short) mode, the terminal acquires a user request, the terminal preferentially sends the user request to a P2P tracker preset server, the user request is a video URL, a mode-hsr flag character is added after the video URL in the user request, and the mode-hsr flag character is used for informing the preset server to execute the data transmission method processing of the embodiment of the invention on the user request.
And secondly, the terminal can ignore the user request which does not carry the high-speed mobile communication identification, continuously initiates the user request and stores the user request to the terminal cache.
In the embodiment of the invention, the terminal can send the user request carrying the high-speed mobile communication identification, and can also send the user request not carrying the high-speed mobile communication identification. In addition, when the terminal is in the process of playing the video online, if a user request is sent to a preset server, the user request carries a high-speed mobile communication identifier, and a preset downloading mode is set by the preset server; and when the current communication network is detected to be available, downloading the data according to a preset downloading mode set by a preset server. Therefore, under the condition that the preset server is in communication connection with the terminal, the terminal detects that the terminal is in a high-speed mobile communication environment, the terminal can quickly download terminal data according to a preset downloading mode set by the preset server under the condition that a network is available, the data volume downloaded by the terminal data is increased, the playing time of the downloaded data volume is prolonged, the times of jamming during playing of the data are reduced, and the user experience effect is improved.
In a third aspect, to reduce the occurrence of stutter during playing data and improve the user experience effect, the scheduler is used for illustration, and an embodiment of the present invention provides a data transmission method, as shown in fig. 5, which may include the following steps:
in step 310, the scheduler receives a user request, where the user request carries a high-speed mobile communication identifier.
Wherein, the user request in the step 310 is the same as the limited content requested by the user in the step 110; in this step 310, the user request may include the high speed mobile communication identifier that is the same as the high speed mobile communication identifier limitation content in the step 102, which can achieve the same beneficial effect and is not described herein again.
This step 310 may specifically include the following steps:
in step 301, the scheduler receives a user request.
Step 302, if it is determined that the user request carries the high speed mobile communication identifier, step 320 is executed.
The determination method of whether the user request in step 302 carries the high-speed mobile communication identifier may further include, but is not limited to: the dispatcher analyzes the received user request and determines each key value pair of a Uniform Resource Locator (URL) of the user request; the dispatcher detects whether each key value pair of the user request URL has a 'high-speed rail mode' character; if each key value of the URL requested by the user has a character of 'high-speed mode', the dispatcher determines that the user request is the user request. So that the scheduler schedules the preset server for the terminal. Step 303 may further include: if each key value pair of the user request URL does not have a character of 'high-speed railway mode', the scheduler determines that the user request is the user request without carrying the high-speed mobile communication identifier, and the scheduler responds to the user request without carrying the high-speed mobile communication identifier.
Following this step 310, the method further comprises:
and 303, if the user request is judged not to carry the high-speed mobile communication identifier, any server of the dispatcher responds to the user request. Here, the user request may be responded by the scheduler returning a server capable of providing a service to the user request of the terminal according to the user request so that the server responds to the user request.
And step 320, utilizing the user request, the scheduler schedules a preset server for the terminal, wherein the preset server allocates a high-priority network data center IDC node for the user request, the high-priority IDC node is determined by the available bandwidth resource of the IDC and the IDC load, so that the request data corresponding to the user request is responded by the high-priority IDC node, and the terminal sends the user request to the scheduler.
The preset server may be obtained in a manner without limitation: sequencing based on the service indexes of the IDC nodes to obtain a sequencing result; and the scheduler allocates a preset server for the terminal from the sequencing result. Here, the sorting may be a reverse order or a sequence. Service metrics may include, but are not limited to: load and available bandwidth resources. The IDC node to which the user requests allocation of a high priority may refer to, but is not limited to, the IDC node that is least loaded and most bandwidth resources available. Therefore, the scheduler can schedule the high-quality IDC nodes for the terminal, and provides reliable guarantee for subsequently improving the data downloading speed for the terminal.
In the embodiment of the invention, the scheduler receives a user request carrying a high-speed mobile communication identifier, schedules the preset server for the terminal according to the user request, and improves and adjusts the data downloading mode of the terminal to the preset downloading mode by the preset server. Therefore, the scheduler can select the preset server, under the condition that the preset server is in communication connection with the terminal, the terminal can quickly download terminal data according to a preset downloading mode set by the preset server under the condition that the terminal detects that the terminal is in a high-speed mobile communication environment, the terminal can quickly download the terminal data under the condition that a network is available, and the data volume downloaded by the terminal data is increased, so that the playing time of the downloaded data volume is prolonged, the times of pause of the data during playing are reduced, and the user experience effect is improved.
