Problems solved by technology
However, the quality of the wireless transmission environment fluctuates greatly and is unpredictable, and the estimation of the transmission time by each video application software (Application, APP) of the terminal is not necessarily very accurate, which will increase unnecessary video service interruption, and may also trigger the base station Some algorithms, such as "terminal discontinuous reception", "user inactive state", "flow control", etc., further lengthen the transmission time of video services
There may be multiple "breakpoint waiting times" during the operation of a video service, which may have a negative impact on the performance of the video service

Embodiment Construction
[0067] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0068] In the embodiment of the present invention, refer to figure 1 As shown, the transmission process of video service data is as follows:
[0069] Step 100: The base station receives the first packet sent by the terminal, and obtains the first parameter carried in the header of the first packet, and the first parameter is used to indicate the first packet used when the server sends video service data. text length.
[0070] Specifically, in...

The invention relates to the field of communication, in particular to a video service data transmission method and device, thereby reducing breakpoint resuming times. The method comprises the following steps: receiving a first message sent by a terminal by a base station; acquiring a first parameter carried in the first message, and updating the first parameter into a second parameter according tothe estimated data volume of video service data which are not transmitted on the server; generating a corresponding second message; further sending the second message to the server; and triggering the server to push the video service data to the terminal according to the second parameter. Thus, the video service data sent to the terminal by the server can be increased; the breakpoint resuming frequency of the video service data is reduced, and the influence of breakpoint resuming on the video service performance is further reduced, so that the breakpoint waiting time can be reduced, the overall rate of the video service is improved, the transmission delay of the video service is reduced, and the perception of a user is improved even under the condition of fluctuation of a wireless transmission environment.
Description
technical field [0001] The invention relates to the communication field, in particular to a video service data transmission method and device. Background technique [0002] At present, most video services on terminals use the Hyper Text Transfer Protocol (Hyper Text Transfer Protocol 1.1, HTTP1.1), and HTTP1.1 supports the "resume function" by default. When the terminal runs video services, it generally establishes multiple Transmission Control Protocol (TCP) connections, and each TCP connection will request to send a piece of video service data to the server one by one, and wait for a piece of video service data to be sent. , the server stops sending video service data until it receives the next request from the terminal, and this time period is called "breakpoint waiting time". [0003] The purpose of HTTP design "breakpoint resume function" is that once the transmission fails due to a problem with the TCP connection carrying the transmitted video service data, then when ...
