Network PerformancesOptimisation Domains

The tests to be performed have been defined into six“Radio Domains”

Domain 1 - Link Budget Validation (Low Load)Domain 2 - UMTS Capacity ValidationDomain 3 - UMTS Co-location Adjacent Channel PerformanceDomain 4 - Radio Resource ManagementDomain 5 - Design Tool ValidationDomain 6 - Radio Processes & Radio Test Tools


Network Performances Radio Optimisation

Radio Resource Management (RRM) is responsible for optimal utilisation of radio interface resourcesTarget for RRM is to ensure the RAN offers:

The planned coverage for each targeted serviceThe planned capacity (new calls, handovers)The required link quality (data rate, error rate, delay)

… to optimise the use of available capacity.


Network PerformancesRadio Optimisation

Coverage, Capacity and Quality

Coverage, capacity and service quality are mutually dependentNode B transmission power, logical resources (codes) and bandwidth are fixed

Ensure that the Equipment, SW Releases, Features and Services are

compliant with the Specifications, functional, operationally stableready to be taken into commercial operations

Guarantee that any new Product or Release is fully compliant with the network configuration.
