Method of content delivery in LTE RAN, an eNB and communication system

摘要

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.

1. A method of content delivery in a Long Term Evolution (LTE) Radio Access Network (RAN), the method comprising:
receiving, by an evolved Node B (eNB) from a user equipment (UE), a client request for requesting content data; checking, by the eNB, a segment map according to the client request; wherein the segment map is configured to store index information of the content data which is divided into a plurality of segments; the segments are distributed in a plurality of eNBs of the RAN; acquiring, by the eNB, the plurality of segments from the plurality of eNBs of the RAN according to the index information in the segment map; generating, by the eNB, the content data by using the plurality of segments; and sending, by the eNB to the UE, the content data.
