Broadband access for all will be a key functionality
in future mobile radio networks. Depending on the length and the
characteristic of the radio wave propagation the performance of
the network is substantially impacted. Especially in urban
application scenarios a ubiquitous reachability is hard to achieve.
In combination this results in high variations of link quality so
that broadband services are hard to realize. This paper discusses a
technique, named Smart Caching, which tries to overcome the
problems of network performance variations. It focuses herewith
on non real time and non interactive services.
Smart Caching follows the approach of pre-fetching and
buffering data at the edge of the core network and transmitting it
whenever the terminal comes into service range of an Access
Point. Especially on motorways this technology can provide
broadband services even under the conditions of intermittent
network coverage.
The mutual reaction of Smart Caching enabled and legacy
services is shown. Additionally dimensioning aspects and the
resulting performance gain is discussed.
The performance of the Smart Caching service is evaluated with a
sophisticated queuing model based on the Markov Arrival
Process. All network characteristics, like arrival and service
process are modeled in very detail.
