摘要： Various examples provide a method of caching service data in LTE networks. A base station parses a data request received from a UE to obtain an identification of requested contents, judges whether the requested contents are cached in the base station, sends the contents to the UE in response to a determination that the requested contents are cached in the base station. In response to a determination that the requested contents are not cached in the base station, the base station judges whether the requested contents are cached in an adjacent base station, and obtains the contents from the adjacent base station and returns the contents to the UE in response to a determination that the requested contents are cached in the adjacent base station. In response to a determination that the requested contents are not cached in adjacent base stations, the base station forwards the data request to an SGW, and returns contents obtained from the SGW to the UE. Various examples also provide another method and apparatus of caching service data in an LTE network. According to the examples, data requests of UEs are not necessarily always forwarded to a business server. Instead, requested data is first sought from a cache (in a base station and/or an SGW) which is the closest to the user to reduce transmission load of the LTE network, reduce the time delay in obtaining service data by users, and improve the quality of experience of users.
