Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 1 shows a schematic flow chart of a video service identification processing method provided in this embodiment, including:
s101, acquiring a downlink data packet which is pre-sent to each terminal, and judging the protocol type of the downlink data packet.
The downlink data packet is sent by the base station side according to the data request after receiving the data request of each terminal.
Wherein the protocol type comprises an HTTP protocol or a TCP protocol.
Specifically, before the base station side sends all downlink data packets, it is necessary to determine the protocol type to which the downlink data packet belongs.
S102, if the protocol type of the downlink data packet is judged to be HTTP, the message content of the downlink data packet is obtained.
Wherein, the message content is the actual content stored in the downlink data packet.
S103, judging the type of the downlink data packet according to the message content, if the type of the downlink data packet is judged to be a data packet of a video service according to the message content, acquiring a target terminal corresponding to the downlink data packet, and improving the priority of sending data to the target terminal.
And the target terminal is a terminal requesting a base station to send the downlink data packet.
Specifically, a terminal a requests a base station for video data, the base station acquires corresponding video data according to the request, before sending the video data to the terminal a, the protocol type of a downlink data packet needs to be determined, when the protocol type of the downlink data packet is determined to be HTTP, the message content of the downlink data packet is acquired, and when the message content is determined to correspond to a video service, the sending priority of the terminal a is increased on the base station side, for example, from 5 to 2, so as to preferentially process the video service.
Video service and video live broadcast users in wireless communication are increasingly large, and the generated flow exceeds 60% of the total flow of mobile users. Because the video service and the live video broadcast are both based on the TCP/HTTP protocol, in the prior art, the optimization of the video service by the base station side is based on a data service optimization mode, only the size of a data packet or the size of flow is distinguished, and a targeted scheme for the service type is not provided. Specifically, a TCP/HTTP message of a video service is transmitted to a base station over an air interface, the base station is encapsulated by a UDP (User Datagram Protocol), and the encapsulated TCP/HTTP message is transmitted to a core network through a GTP (GPRS tunneling Protocol) tunnel through an S1 port, so as to identify a video User at the base station side, and then the identified video User is adjusted by differentiated wireless parameters, so as to achieve specialized optimization of all video users.
In the embodiment, the message content of the downlink data packet of the HTTP protocol type is judged, and if the data packet is a video service data packet, the priority of sending data to the target terminal is increased, so that accurate identification of a video service user is realized, and the data packet is distinguished at the base station side, so that configurable optimization processing of the video service is realized, and the use requirements of the user are met.
Further, on the basis of the above embodiment of the method, after S103, the method further includes:
and S104, if no downlink data packet sent to the target terminal exists after the preset time interval is judged, restoring the priority of the data received by the target terminal to the initial value.
The preset time interval is a preset time interval.
In order to reduce the load of the base station, if the downlink data packet of the target terminal is already sent after a preset time interval, the priority of the data received by the target terminal is restored to the initial value. And if the downlink data packet of the target terminal is not sent completely after the preset time interval, continuously maintaining the high priority of the target terminal for receiving the data.
Further, on the basis of the above method embodiment, the determining, in S103, that the type of the downlink data packet is a data packet of a video service according to the message content specifically includes:
and if the message content is judged to contain the video keywords, determining that the type of the downlink data packet is a data packet of the video service.
Wherein the video keywords comprise video, mp4, stream, flv, or mp2 t.
Fig. 2 is a typical video service flow chart based on a mobile network, which mainly includes a wireless access process of a control slice, a DNS (Domain Name System) query of a user plane, a TCP link establishment process, and an HTTP download process. Fig. 3 is a TCP protocol of a package capture content of a one-time tv drama service of an Tencent video android client, where the content in the dotted line frame at the upper right part is a download part of video content; the solid frame part is a characteristic field sent through an HTTP protocol plaintext when the segmented video data is normally finished, the field is sent to a mobile phone terminal by a server to tell that the video Content or the segmented video Content is completely transmitted and to tell the terminal that the Content data amount, the calculation unit, the keep-alive time and the Content Type of the video or the segmented video data are all transmitted, wherein the Content-Type marked in the lowermost solid frame is the Content Type, and the video keyword in the downlink data packet needs to be identified in the embodiment.
Specifically, the data transmission process and the four waving processes of TCP link tear-down are both TCP protocols, and the data volume is large and is not a plaintext message, so for HTTP/1.1200OK (complete packet end message) or HTTP/1.1206 Partial (segmented download end message) based on the HTTP protocol, the base station recognizes that there are advantages of small data volume and recognizable plaintext message.
The specific judgment and processing flow is shown in fig. 4, and after a downlink data packet is captured, whether the downlink data packet adopts the HTTP protocol or the TCP protocol is judged. If the TCP protocol is adopted, no special processing is carried out; if the HTTP message contains the HTTP protocol, judging whether the HTTP header contains HTTP/1.1, if not, not processing, if yes, continuously judging whether 200OK or 206Partial fields exist after HTTP/1.1, if yes, analyzing whether video keywords such as video, mp4 and stream are contained in the message content of the HTTP message, and if not, not processing; and if the downlink data packet contains the information, recording information such as an IP (Internet Protocol) address and a User Equipment identity (UE ID) of the User corresponding to the downlink data packet, improving parameters such as an access priority and an uplink pre-scheduling of the User, and improving User perception of the User. When the downlink data packet is not sent to the user after the preset time interval, returning parameters such as the access priority, the uplink and the scheduling of the user; and when the downlink data packet is continuously sent to the user after the preset time interval, maintaining the parameters of the user, such as access priority, uplink, scheduling and the like.
Specifically, as shown in the following table, from the summary of the feature words of the captured downstream packets, at least one keyword among video, mp4, stream, flv, and mp2t is included, and can be easily identified by the above video keywords, and the mainstream video identification rate is expected to be 100%.
As an identification scheme of a base station for video users, the embodiment can perform differentiation processing on users after identification while overcoming the defect that the existing base station lacks an efficient and accurate identification scheme for video user identification, and belongs to a solution promotion scheme of a targeted strategy for promoting the perception of video users by an operator in recent years. The method has the characteristics of high identification accuracy and high identification efficiency on the aspects of optimizing video services at a base station and even a wireless side. The method is different from the traditional extensive optimization strategy of dividing the data packet into a large packet, a medium packet and a small packet, and can meet the requirement of customer examination. The method has great value for improving the product competitiveness and the customer satisfaction.
