Third generation mobile systems are driving a multi-system network landscape. Network management is crucial to guarantee optimum cooperation between network sub-systems. The aim of the GANDALF project is to use large scale network monitoring, advanced RRM rules and appropriate quality of service evaluation in order to achieve automation of network management tasks in a multi-system environment (GSM, GPRS, UMTS and WLAN). The GANDALF project will contribute to the following areas:

  • Optimisation of the use of the available radio resources
  • Provision of seamless services
  • Monitoring and evaluation of Global user-perceived QoS for multi-system networks including WLAN
  • Enhancement of global user perceived QoS
  • Automated network management

The project will develop appropriate techniques to collect and process network data on a large scale in order to produce key performance indicators allowing identifying malfunctions and / or to dynamically propose and perform healing actions. To optimise QoS delivery and overall systems performance in a multi-system environment, the project will propose new radio resource management algorithms together with methods for self-tuning. The project will demonstrate through network simulations the feasibility of the multi-system self-tuning concept. Finally, hardware demonstrations will also prove the viability of the ARRM and auto-tuning concepts developed in the project.

Focus areas
  • Large scale network monitoring, advanced RRM rules QoS evaluation for automated network management for multi-system environment
  • Optimisation of the use of the available radio resources
  • Provision of seamless services
Expected outcome
Generate and analyze by simulation:
– network architecture specifications,
– performance indicators,
– resource management algorithms,
– optimisation algorithms and emulation methods
