Problems solved by technology

At present, there is no public simulation method that can simulate and evaluate the next generation wireless communication system based on the distributed cell structure
However, the existing simulation methods and simulation software all adopt a process-oriented method, and do not consider various physical objects in the system such as mobile stations, base station transceivers, base station controllers, etc., but only care about the various entities in the communication process. A change in a parameter
The emulator constructed by this method is relatively simple to implement, but it lacks openness and dynamics. Once there are new technologies or functions that need to be added, it is necessary to restructure the emulator or disrupt the structure of the platform, and the simulation scene cannot Arbitrary settings according to user requirements
In addition, the method of cyclic simulation according to sampling snapshots often needs to consider two issues: simulation efficiency and simulation accuracy
Existing methods can only take care of one of these two problems, either high efficiency but low accuracy, or high accuracy but long simulation time

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Referring to Fig. 1, the present invention is made of five parts of mobile station MT (Mobile Terminal, can be B3G mobile phone, PDA etc.) module, access point AP (Access Point) module, wireless environment module, statistics module and emulator main control. Among them, the object-oriented design concept is adopted for the mobile station MT and the access point AP module, which is used to simulate the user terminal and access point in the actual network. The parameters are determined during the scene initialization, including ID, location, motion parameters, and service parameters. Parameter information such as antenna height and location update, service update, sending and receiving and other behavior and algorithm modules; the wireless environment module simulates path loss, shadow fading and multipath according to the geographical environment, the l...

Abstract

The dynamic simulation method for air interface in wireless communication system comprises: by OO method, building and configuring all simulation entities in system to form communication network; applying entity to simulate communication process between terminal and access point under main control program with dual-loop cycle. This invention aims to build network simulator fit to B3G air interface to obtain and evaluate interface reference performance and technique.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and mainly relates to a simulation test method of a new generation cellular wireless communication system, in particular to a dynamic simulation method of an air interface of a wireless communication system. Background technique [0002] Since the first cell-based cellular mobile communication system established by Bell Laboratories in the United States in 1978, mobile communication has rapidly become an indispensable part of people's lives. With the continuous growth of people's demand for mobile communication, mobile communication gradually develops from low speed to high speed, from analog communication to digital communication. Today, as the third-generation cellular mobile communication system (3G) with CDMA technology as the core enters the commercial stage in various countries, countries around the world have also launched research on the next-generation cellular wireless co...
