Abstract: The present disclosure discloses cache-based data transmission methods and apparatuses. The method is implemented as follows. An apparatus where a caching node is located reports a caching capability to a network side, and the caching node is configured to cache data. The network side sends a cache indicating parameter to the apparatus where the caching node is located, and maintains a data list. Wherein, the cache indicating parameter is configured to control the caching node to cache the data which has the property of high repetition probability and/or high cache utilization, and the data list is a list of the data cached in the caching node. When the caching node has cached data requested by a UE, the UE obtains the requested data from the caching node.

Abstract translation: 本公开公开了一种基于高速缓存的数据传输方法和装置。 该方法实现如下。 高速缓存节点所在的装置向网络侧报告缓存能力，并且缓存节点被配置为缓存数据。 网络侧向高速缓存节点所在的设备发送缓存指示参数，并维护数据列表。 其中，缓存指示参数被配置为控制高速缓存节点来缓存具有高重复概率和/或高缓存利用率的属性的数据，并且数据列表是缓存在高速缓存节点中的数据的列表。 当高速缓存节点缓存由UE请求的数据时，UE从缓存节点获取所请求的数据。
