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.
