Perspectives on a 6G Architecture
Mobile communications have been undergoing a generational change every ten
years. Whilst we are just beginning to roll out 5G networks, significant
efforts are planned to standardize 6G that is expected to be commercially
introduced by 2030. This paper looks at the use cases for 6G and their impact
on the network architecture to meet the anticipated performance requirements.
The new architecture is based on integrating various network functions in
virtual cloud environments, leveraging the advancement of artificial
intelligence in all domains, integrating different sub-networks constituting
the 6G system, and on enhanced means of exposing data and services to third
parties.Comment: 7 pages, 5 figures, one tabl
LTE for public safety
The aim of the book is to educate government agencies, operators, vendors and other regulatory institutions how LTE can be deployed to serve public safety market and offer regulatory / public safety features. It is written in such a way that it can be understood by both technical and non-technical personnel with just introductory knowledge in wireless communication. Some sections and chapters about public safety services offered by LTE network are intended to be understood by anyone with no knowledge in wireless communication
ePERT: Extending PERT for Workflow Management Systems
Workflows management systems support the definition and execution of business processes. While business process reeingeneering tools use time information to simulate and optimize processes, the management of time is hardly supported in workflow systems. We introduce a concept for time management for workflow systems. It consists of calculating internal deadlines for all activities within a workflow, checking time constraints and monitoring time at run-time. For the calculation of internal deadlines we extend the netdiagram technique PERT to support the structures usually found in workflows. At run-time this time information is used to pro-acticely avoid time errors and reactively resolve time failures. The concept has been implemented in our prototype workflow management system Panta Rhei.
