Service data cache processing method and system and device

A cache policy control entity, comprising:

• processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program includes instructions to instruct the processor to:
• receive, with respect to service data to be provided to a user equipment (UE), through a core network and through a radio access network, statistical information of the service data, wherein the core network is different from the radio access network, and the radio access network is a local wireless communication network where the UE is located, wherein the UE communicates with the core network through the radio access network, and wherein the service data is provided by a service provider (SP) device from a location that is outside the radio access network;
• make a determination, according to the statistical information, as to when to perform a tiered caching of the service data, and when to perform a direct caching of the service data in the radio access network, wherein the tiered caching is performed by first caching the service data in the core network with a primary cache deployed in the core network, before the service data is moved into and cached in the radio access network, and wherein the direct caching in the radio access network is performed by directly caching the service data in the radio access network with an edge cache deployed in the radio access network, without first caching the service data in the core network;
• and
• send a service data push request to the SP device, for the SP device to send the service data corresponding to the service data push request to the primary cache deployed in the core network, when it is determined to perform the tiered caching of the service data, and to the edge cache deployed in the radio access network, when it is determined to directly cache the service data in the radio access network;
• wherein each of the SP device, the primary cache, the edge cache, and the UE are different and separate from one another;
• and
• wherein the statistical information comprises any one or a combination of the following:
• information of the service data whose access traffic is greater than a first preset value;
• information of the service data whose attention degree is greater than a second preset value;
• and
• information of the service data that comprises a preset keyword.

A network device, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program includes instructions to instruct the processor to:
• acquire, with respect to service data to be provided to a user equipment (UE), through a core network, and through a radio access network, statistical information related to the service data, wherein the core network is different from the radio access network and the radio access network is a local wireless communication network where the UE is located, wherein the UE communicates with the core network through the radio access network, and wherein the service data is provided by a service provider (SP) device from a location that is outside the radio access network;
• make a determination, according to the statistical information, as to when to perform a tiered caching of the service data, and when to perform a direct caching of the service data in the radio access network, wherein the tiered caching is performed by first caching the service data in the core network with a primary cache deployed in the core network, before the service data is moved into and cached in the radio access network, and wherein the direct caching in the radio access network is performed by directly caching the service data from the SP device in the radio access network with an edge cache deployed in the radio access network, without first caching the service data in the core network;
• and
• send the statistical information to a cache policy control entity, so that the cache policy control entity can request the SP device to send the service data corresponding to a service data request to the primary cache deployed in the core network, when it is determined to perform the tiered caching of the service data, and to the edge cache deployed in the radio access network, when it is determined to directly cache the service data in the radio access network;
• wherein each of the SP device, the primary cache, the edge cache, and the UE are different and separate from one another;
• and
• wherein the statistical information comprises any one or a combination of the following:
• information of the service data whose access traffic is greater than a first preset value;
• information of the service data whose attention degree is greater than a second preset value;
• and
• information of the service data that comprises a preset keyword.
