Self organization and self optimization of wireless networks with partial system knowledge

未来，移动通信网络将需要提供新的服务，因此必须满足有关数据速率、稳定性和连接性以及其他定性标准的新要求。由于越来越多的用户的高度移动性，网络必须几乎无处不在，并且始终可用。另一方面，网络和所提供服务的成本不能太高。如果网络本身能够以较低的成本运行和维护，网络供应商和网络提供商就具有竞争优势。例如，如果相邻的基站可以单独提供相同质量的服务，则可以通过关闭不再需要的基站来实现节省。从本质上讲，未来的移动通信网络必须具备适应时变服务质量需求的能力。他们还必须能够对有害的变化和异常迅速作出反应。因此，在所要求的研究计划框架内，将开发和研究系统不确定性下的无功自优化方法。为了支持底层系统的复杂计算，另一方面，也为了实现低复杂度的优化，有必要使用描述基本因果关系和依赖关系的近似方法。这一课题的处理对于未来移动通信网络自组织的长期相关性以及移动通信网络标准LTE （Long Term Evolution）和LTE- a的成功具有重要意义。在这项研究的框架内计划的工作，以及来自不同工程和数学领域的基本原则，将在以下建议中解释。

In the future, mobile communication networks will need to provide new services and therefore will have to fulfill new requirements regarding data rates, stability and connectiveness, as well as other qualitative criteria. Because of the high mobility of an increasing number of users, networks must be virtually everywhere and consistently available. On the other hand, costs for the networks and the services provided cannot be too high. If the networks themselves can be run and maintained for low cost, the network supplier and network provider have a competitive edge. For example, savings can be achieved by shutting down a base station that is no longer needed, if the same quality of service can be provided by a neighboring base station alone.Essentially, future mobile communication networks must be equipped with the capability to adapt to time-variable quality of service requirements. They also must be able to react quickly to harmful alterations and anomalies. Therefore, within the framework of the requested research proposal, methods of reactive auto-optimization under system uncertainty will be developed and researched. In order to support the complex calculations of the underlying systems, and on the other hand, to also enable an optimization with a low complexity, it is necessary to have methods of approximation that portray the essential causations and dependencies. The treatment of this topic is of major importance for the long-range relevance of future mobile communication networks self-organization as well as to the success of the mobile communication network standards LTE (Long Term Evolution) and LTE-A. The work that is planned within the framework of this research, as well as the fundamental principles from the varying areas of engineering and mathematics, is explained in the following proposal.
