Control method and system for information delivery through mobile communications network
First Claim
1. A control method for information delivery for a mobile communications network including a plurality of communication nodes, comprising:
- a step of identifying a first cache node storing cache information in a first delivery channel established in response to a delivery request for original information from a mobile terminal staying in a first communication area, wherein said cache information is identical to said original information;
a step of identifying a second cache node storing cache information in a second delivery channel while said mobile terminal is receiving said cache information from said first cache node through said first delivery channel;
a step of sending by said first cache node to said second cache node a first signal indicating that a portion of said cache information has been delivered to said mobile terminal by said first cache node; and
a step of delivering said cache information except for said portion of said cache information in response to said first signal from said second cache node to said mobile terminal in a second communication area.

Abstract
A control method and system for information delivery in a mobile communications network in which, as a mobile terminal moves from a communication area to another, a cache node in a delivery channel which delivers cache information to the mobile terminal is switched to another cache node in another delivery channel to reduce information traffic in the network utilizing the cache function of the cache nodes. After a portion of cache information is delivered by a cache node to the mobile terminal, only the remaining portion of cache information is delivered by another cache node.
