Definitions
- the present invention relates to a device and a method for simulating a mobile telecommunication network.
- a simulation process aims to evaluate the capacity of a mobile or cellular network to support the load of a number of mobile users deployed in a quasi-random manner and whose different types of needs, for example in voice , video, web, also differ randomly.
- the radio resource In a mobile network, the radio resource is the main bottleneck because of its scarcity.
- Each generation of mobile network brings major technological innovations to optimize the use of this resource, while taking into account the evolution of uses.
- This evolution is accompanied by an increased complexity at the level of the scheduler (in English "scheduler") whose mission is to dynamically optimize the allocation of the radio resource between different mobiles.
