Abstract: Embodiments of the present disclosure provide a cache data obtaining method. After detecting a first request message specific to a target data server, a data request device determines, based on a pre-received local cache device list sent by a base station, a target local cache device used to cache service data of the target data server. Subsequently, the data request device establishes a network connection to the target local cache device, and sends a service data request specific to the target data server to the target local cache device by using the network connection. With data of the target data server cached to a local cache device on a base station side, the data request device can directly request the target service data from the target local cache device.
