Data caching method and storage medium

A data caching method, comprising steps of:

• receiving a cache request sent by user equipment (UE), wherein the cache request is configured to request to cache service data;
• acquiring first network status data between a small cell base station (SBS) accessed by the UE and the UE, second network status data between a macro-cell base station (MBS) corresponding to the SBS and the UE, and third network status data between the UE and a data source of the service data, respectively;
• acquiring, according to the types of the first network status data, the second network status data, the third network status data, and the service data, three corresponding user quality of experience (QoE) values, respectively;
• and
• determining whether a cache is configured for the UE according to the three QoE values,
• wherein determining whether a cache is configured for the UE according to the three QoE values comprises:
• when QoEsource corresponding to the third network status data is the largest of the three QoE values, determining not to configure the cache for the UE;
• otherwise, determining to configure the cache for the UE,
• wherein determining to configure the cache for the UE comprises:
• determining whether each of the SBS and the MBS has a cache space;
• and
• configuring the cache for the UE according to a first determining result,
• wherein configuring the cache for the UE according to the determining result comprises:
• comparing the size of QoEMBS corresponding to the second network status data and the size of QoESBS corresponding to the first network status data when the first determining result is that the SBS has the cache space;
• determining that the SBS configures the cache for the UE when QoESBS>QoEMBS;
• determining whether the MBS has the cache space when QoESBS<QoEMBS;
• and
• configuring the cache for the UE according to a second determining result, and
• wherein configuring the cache for the UE according to a second determining result comprises:
• determining that the MBS configures the cache for the UE when the second determining result is that the MBS has the cache space;
• otherwise, comparing the size of the QoEsource and the size of the QoESBS;
• and
• determining that the SBS configures the cache for the UE when QoESBS>QoEsource.
