A cache optimization method and a storage medium

The invention relates to a cache optimization method and a storage medium. The method comprises the following steps: receiving a cache request sent by UE, judging whether a small base station SBS accessed by the UE and a macro base station MBS corresponding to the SBS have a cache space or not; when the SBS and the MBS have no cache space, the cache space of the SBS and the MBS is optimized for the first time according to the repetition degree of the cache content, and after optimization for the first time, if the SBS or the MBS has the cache space, the cache is configured for the UE. Redundant caches in SBS are reduced, waste of SBS and MBS cache space is reduced, and the effective utilization rate of the base station cache space is improved. 本发明涉及一种缓存优化方法及一种存储介质，包括：接收到UE发送的缓存请求时，判断UE接入的小基站SBS和SBS对应的宏基站MBS是否有缓存空间，当SBS和MBS都没有缓存空间时，根据缓存内容的重复度对SBS和MBS的缓存空间进行第一次优化，经过第一次优化后，若SBS或MBS有缓存空间，为UE配置缓存。减少了SBS中的冗余缓存，减少了SBS和MBS缓存空间的浪费，提高基站缓存空间的有效利用率。
