  • Method of content delivery in LTE RAN, an eNB and communication system
    Patent number: 9432440
    Abstract: The embodiments of the present invention provide a method of content delivery in LTE RAN, an eNB and communication system. The method includes: receiving, by an eNB from an UE, a client request for requesting content data; checking a segment map according to the client request; acquiring the plurality of segments from one or more eNBs of the RAN according to the index information in the segment map; generating the content data by using the plurality of segments; sending the content data to the UE. In this invention, a content data is divided into a plurality of segments and the segments are distributed in a RAN. Furthermore, the content data is acquired from neighboring nodes of RAN as much as possible, such that cache hit ratio is improved and the link between RAN and CN is saved.
