METHOD AND SYSTEM FOR CACHING CONTENT ON-DEMAND IN A WIRELESS COMMUNICATION NETWORK
First Claim
1. A method for caching content in a wireless communication network, the method comprising:
- caching a first fragment of a content at a first base station, wherein the first fragment comprises a plurality of packets;
transmitting one or more packets of the plurality of packets corresponding to the first fragment to a mobile station;
initiating a handover of the mobile station to at least one second base station; and
caching a remaining plurality of packets corresponding to the first fragment at the at least one second base station in response to initiating the handover.

Abstract
The present invention provides methods and systems for caching content in a wireless communication network. The method includes receiving a request for a content at a first base station from a mobile station. In response to receiving the request for the content, the first base station caches a first fragment of the content. The first fragment includes a plurality of packets. Further, the first base station transmits one or more packets of the plurality of packets corresponding to the first fragment to the mobile station. The method further includes initiating a handover of the mobile station to at least one second base station. The at least one base station caches a remaining plurality of packets corresponding to the first fragment of the content in response to the handover.

11. A method of initiating a handover of a mobile station from a first base station to a second base station, the first base station transmitting a content to the mobile station, the method comprising:
-
receiving a tag index corresponding to a last packet of one or more packets of a plurality of packets corresponding to a first fragment transmitted to the mobile station from the first base station; identifying a remaining plurality of packets corresponding to the first fragment based on the tag index, wherein the remaining plurality of packets corresponding to the first fragment is subsequent to the one or more packets in the first fragment; and caching the remaining plurality of packets corresponding to the first fragment at the second base station.

12. A system for caching content in a wireless communication network, the system comprising:
-
a first caching module, the first caching module configured to cache a first fragment of a content at a first base station, wherein the first fragment comprises a plurality of packets; a transmitting module, the transmitting module configured to transmit one or more packets of the plurality of packets corresponding to the first fragment to the mobile station; an initiating module, the initiating module configured to initiate a handover of the mobile station to at least one second base station; and a second caching module, the second caching module configured to cache a remaining plurality of packets corresponding to the first fragment at the at least one second base station in response to the initiating module initiating the handover. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
