Problems solved by technology

Since static simulation can only give a limited number of rough simulation results, it is difficult to meet the needs of 3G mobile communication system network planning and optimization. Therefore, dynamic simulation has attracted more and more attention from the industry.
[0013] However, due to the complexity of the well-known dynamic simulation system and method itself, compared with static simulation, the biggest disadvantage of dynamic simulation is that the simulation time is too long, and the system runs very slowly, so that dynamic simulation has not yet been used in actual networks. It has been well used in planning and optimization, and people in the industry are exploring how to apply dynamic simulation methods to the simulation of the third-generation mobile communication system, and can quickly provide simulation results to provide a basis for network planning and optimization of 3G mobile communication systems. good reference

Description

technical field [0001] The invention relates to a dynamic simulation device and method for network layer performance of a third-generation mobile communication system, and belongs to the technical field of network layer simulation of wireless communication systems. Background technique [0002] With the maturity of the third generation mobile communication technology, the network planning of the third generation mobile communication system has been put on the agenda. In order to build an economical, practical and efficient third-generation mobile communication system, network planning and optimization must be carried out. [0003] At present, most of the simulation methods used for network planning and optimization are traditional static simulation methods. According to the Monte Carlo simulation idea, the simulation method uses snapshot mode for simulation. In each round of snapshot simulation, the user terminal (UE) is activated For the fixed connection relationship with ...
