It is generally recognized that wireless access is getting more and more the preferred way to interact with services. For critical services the reliability of the service session is crucial. We propose a modelling approach for prediction of the reliability of a session in a multi operator multi technology wireless environment. The model allows comparison of different trajectories of access points...
Our every day life is getting more and more dependent on wireless access to the desired private, business or machine-to-machine related services and applications. Among these, critical services put the highest requirement on service continuity, i.e. the probability of obtaining an uninterrupted service should be as close to one as possible. Multi homing can be used to increase the service continuity...
The operator diversity of different wireless and cellular networks integrated by IP-based networks does not imply independencies in the respective access networks. We have used incident and change records covering more than 1000 days from a GSM/UMTS network operator. Service failures vs. population density and time periodicity of failures have been studied. Our results indicate higher failure intensity...
