The present invention relates to a method for optimizing a real cellular, wireless communication network that combines mobility load balancing (MLB) with coverage and capacity optimization (CCO) in a joint and coordinated optimization. An optimal set of physical base station parameters is determined by performing an iterative direct search. The iterative direct search comprises a partitioning strategy to jointly determine an optimal partition of the served area and an associated optimal load of each of the plurality of base stations for a current set of physical base station parameters for each direct search iteration; said partitioning strategy using an updated value of the received power of the pilot or reference signal for each the plurality of user locations associated with the current set of physical base station parameters for each direct search iteration.

A system, method, and computer program product are provided for creating cellular network performance indicators by correlating business data of subscribers with a geographic position. In use, one or more subscriber measurement reports associated with an authenticated cellular network subscriber identifier are received. Additionally, the one or more subscriber measurement reports are geo-location tagged with a geographic position estimate. Further, business data associated with the authenticated cellular network subscriber identifier is received. Moreover, the received business data is associated with the one or more corresponding subscriber measurement reports, based on the authenticated cellular network subscriber identifier, such that the business data is associated with the geographic position estimate to create one or more performance indicators.

A method is provided for planning and optimizing the configuration of a radio access network which comprises base stations and receivers and employs a mobile radio technology that allows and/or enforces use of multi-antenna types at said base stations and receivers. By a ray tracing algorithm which is performed between said transmitter positions and said receiver positions using a 3D clutter height matrix, a scalar metric is determined for each receiver position which directly reflects a capacity gain resulting from applying a multi-antenna type instead of a single antenna at said transmitter and receiver positions. This scalar metric allows in an algorithmically advantageous way to analyze the relative performance of different MIMO antenna types in a potential deployment area and to select and deploy an optimal MIMO antenna type for a particular coverage sector.

A method of optimising real cellular, wireless communication networks comprising the steps of providing location-referenced values of subscriber traffic for area elements; transmitting a reference signal of constant transmission power; providing a cell-referenced value of the power received from the reference signal; providing a model of the communication network having an original model network configuration, and iteratively optimising the model network configuration by accumulating and weighting the subscriber traffic values of the area elements and by locally adjusting the model network configuration, to provide an optimised model network configuration.

In a method for controlling sequential object-oriented system-simulations, presentation of an object of a group of objects to an instance-to-class is carried out in the following manner. The instance is produced by adjusting at least one parameter in the part of a simulation program. The instances produce and treat events for simulating a communication between objects, the simulation process being controlled by the activation of instances. The simulation process control is carried out according to a cycle consisting of determined cycle steps, the events being recorded in an event-recording area which is assigned to a target instance.
