Service caching method and device based on mobile edge computing as well as serving base station

Abstract

The embodiment of the invention provides a service caching method and device based on mobile edge computing as well as a serving base station. The service caching method comprises the following steps:receiving a first video service request sent by a serving base station, wherein the first video service request is used for requesting acquisition of play resources of a target video; and sending pre-cached play resources of the target video to the serving base station, wherein the pre-cached play resources are part of play resources of the target video, and quantity of the pre-cached play resources is determined according to service features of the target video. The method provided by the embodiment of the invention caches part of play resources of the target video, so that only the part ofplay resources cached are sent to a serving base station of a user in an initial caching stage when the user watches the target video, and round-trip delay in the initial caching stage when the user watches the video can be reduced under the premise that an MEC load and cost are not increased.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a service caching method, device and service base station based on mobile edge computing. Background technique [0002] Under the existing technology, downloading videos from video service base stations (such as Tencent, iQiyi, etc.) and then playing them on terminals has become the demand of a large number of users. times (such as 720P), the minimum rate that the network needs to provide should be the video buffer rate, so it has higher requirements for network coverage and capacity. If a large number of users watch videos at the same time, the user's initial buffering delay will be prolonged and user experience will be degraded. [0003] Currently, Mobile Edge Computing (MEC for short) is applied in video playback. Mobile edge content and computing technology is to provide information technology service environment and cloud computing capabilities at a location clos...

Problems solved by technology

[0004] In the existing technology, in order to ensure that all users can watch the requested videos in a timely manner, a large number of complete video resources are cached locally in the MEC. However, the types of videos cached in this way are very limited. All cached on the MEC, the load on the MEC is high, and the cost of hardware (such as service base stations, hard drives, etc.) is high, which affects the advantages of MEC sinking
