AI Technical Summary

Problems solved by technology

[0004] 1. When the user initially plays the video, it needs to wait for a long time;
[0005] 2. When the video is played on the terminal, the pause phenomenon is serious;
[0006] 3. The waste of video information traffic is serious;
[0007] 4. The repeated download rate of popular videos is high, which not only increases the operator’s inter-network settlement fees, but also increases the end-to-end (E2E) network load, and even aggravates network congestion during busy hours, reducing user experience
[0014] The disadvantage of this existing technology is that it is mainly suitable for the serial injection of content for a single client, but not for the concurrent access of single or multiple clients, that is, it is difficult to achieve concurrent injection of video content

Embodiment 1

[0123] The implementation scenario of the first embodiment is: multiple UEs access the same video content concurrently, and the metadata corresponding to the video content is missed locally in the Cache.

[0124] In the scenario of this example, you can use the following Figure 7 The steps shown implement injecting the streaming media segment of the video content into the Cache. Specifically, these steps include:

[0125] Step 71, multiple UEs concurrently send to the Cache a video content access request for requesting to obtain a streaming media segment of the same video content;

[0126] Wherein, the streaming media segments of the video content requested by the video content access requests sent by different UEs may be completely different, or partly or completely the same.

[0127] Step 72, the Proxy Server located between the UE and the Cache intercepts the video content access request sent by the UE, and sends the intercepted video content access request to the Video ...

Embodiment 2

[0160] The implementation scenario of the second embodiment is: multiple UEs access the same video content concurrently, and the local part of the Cache hits the metadata corresponding to the video content.

[0161] In the scenario of this example, you can use the following Figure 8 The steps shown implement injecting the streaming media segment of the video content into the Cache. Specifically, these steps include:

[0162] Step 81, multiple UEs concurrently send video content access requests for obtaining the same video content to the Cache;

[0163] Wherein, the video content access requests sent by different UEs request to obtain the streaming media segments of the video content that may be completely different, or partially or completely the same.

[0164] Step 82, the Proxy Server located between the UE and the Cache intercepts the video content access request sent by the UE, and sends the intercepted video content access request to the Video Cache;

[0165] Step 83:...

Embodiment 3

[0192] The implementation scenario of the third embodiment is: multiple UEs access the same video content concurrently, and the Cache locally completely hits the metadata corresponding to the video content, but the video content stored in the Cache represented by the metadata is incomplete.

[0193] In the scenario of this example, you can use the following Figure 9 The steps shown implement injecting the streaming media segment of the video content into the Cache. Specifically, these steps include:

[0194] Step 91, multiple UEs concurrently send video content access requests for obtaining the same video content to the Cache;

[0195] Step 92, the Proxy Server located between the UE and the Cache intercepts the video content access request sent by the UE, and sends the intercepted video content access request to the Video Cache;

[0196] Step 93: According to the above-mentioned intercepted video content access requests sent by the Proxy Server, the Video Cache queries the...

Abstract

The invention discloses a method and equipment for injecting stream media fragments into a cache system and the cache system, which aims at providing a scheme of supporting the stream media fragments to be injected into the cache system in a parallel way. The scheme is characterized in that a read-write lock is distributed for the stream media fragments to be injected into the cache system, so the stream media fragments provided with the read-write lock can only be subjected to read and write by one terminal within one period. As the conflict is avoided between the read and write operations of the same stream media fragment by different terminals, the different stream media fragments of the stream media content can be injected into the cache system in parallel.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and cache system for injecting streaming media segments into a cache system. Background technique [0002] With the popularization of smart terminals and the rapid development of mobile broadband (MBB) services, mobile video services, that is, the services of watching or downloading video information through mobile networks, have become the fastest-growing services on the Internet. Video information on the existing network For the first time, the traffic exceeds the information traffic of the mobile World Wide Web (Web) business (that is, the business of accessing the Web through the mobile network). According to the prediction of authoritative professional organizations, the video information traffic in the mobile network will still maintain a growth rate of 100% to 400% in the next 10 years. Due to the large bandwidth consumption, high duty cycle and hi...
