Description
Technical field
The invention belongs to communication technique field, the driving method being related in a kind of system integration project is specially wirelessly communicated
Time driving and event driven hybrid driving method are based in system emulation.
Background technique
The emulation mode of wireless communication system is broadly divided into two kinds: link level simulation and system integration project.System integration project
There are two types of the methods of mainstream altogether: STATIC SIMULATION and dynamic simulation.
STATIC SIMULATION, also referred to as snapshot.A certain number of snapshots are carried out by the scene to mobile radio system to grab
It claps, an ideal system equalization point is established to the snapshot captured each time, by the performance for statisticalling analyze whole system.It is united
The number that average precision depends primarily on candid photograph is counted, number is very little, and confidence level will reduce if captured, however if captures
Number is too many, can greatly increase the complexity of emulation.
Dynamic system simulation method then considers the real-time change of the motor behavior of multi-user and network service under multiple cells
Change, needs constantly to collect the measured value of user side or network side, the Service Quality Metrics of various businesses are counted with this, it can
To provide complete capacity and covering analyzing, but operand is larger, and emulation cycle is longer, it is therefore necessary to carry out simplification and examine
Consider, under normal circumstances, the modeling method of dynamical system can be divided into two classes: time driving type and event driven.
The dynamic simulation of time driving type carrys out more new data as unit of time step, each time step is as one
Reference point, system it is each emulation reference point update user motion state, calculate user reception power, assessment cell to
The service quality at family adjusts power level and update customer service etc. according to QoS demand.
Event driven dynamic simulation is using a network snapshots as reference, the event to be driven such as in certain period of time
Generation, it reflects quality of service by the mobility and business procedure of analog subscriber.It is emulated compared to time driving type, thing
The time sampling frequency of the driving emulation of part wants lower, relatively low to the simulation accuracy of business procedure.
Existing overwhelming majority wireless communication system grade emulation platform is all using single time driven manner or event
The system integration project of driving method, similar LTE-A cellular topology has apparent temporal characteristics, is suitble to the side using time driving
Formula, and similar WALN system emulation is then not suitable for time driving, regular time sample frequency can not embody the spy of WALN
Point, at this time event-driven just compares and is suitble to him.Time driving and event-driven are then used in mixed way by the present invention, in heterogeneous network
The characteristics of different type network is sufficiently adapted in system integration project is promoted while reducing time sampling frequency to business procedure
Simulation accuracy.
As shown in Figure 1, time driving method is to divide different operations according to constant duration, whenever operating pointer arrives
A defined time point is reached, driving engine accordingly starts to execute operation, in this case can be with the increase of sample frequency
And increase the accuracy of emulation；Event-driven method is quite different, and the condition of each event triggering is different, whenever the touching of event
Clockwork spring part, which is triggered, drives engine that can then start to execute the event, as long as so we will emulation split into different events, and
To every kind of event defined attribute, executed according to the timestamp of event, in this case there is no need to pass through as time driving
Sample frequency is adjusted to control simulation process, greatly reduces the complexity of emulation.
