Network quality measurements, specifically: above-mentioned network quality parameters and local preset are worked as judgement first net by the second emulator
In network mass parameter group or the second network quality parameters group there are any one network quality parameters value do not meet it is any one with this
When network quality parameters are worth corresponding preset condition, the second emulator keeps present communications process；Second emulator is according to above-mentioned
It is unsatisfactory for any one network quality parameters value of preset condition, determines network quality fault point and network optimization scheme.Wherein,
Determine the method for network quality fault point and network optimization scheme according to network quality parameters value according to network quality parameters value
Difference and it is different, for example, in IP bearer network, when packet loss is unsatisfactory for preset condition, it may be possible to due to CE to probe chain
Packet loss caused by the failure of road.
In above process, network quality parameters are percent of call completed, single-pass rate, noiseless rate, packet loss etc.；Above-mentioned preset condition
Acquisition is preset by user for specific network condition, for example, percent of call completed meets pre- when more demanding to network communication quality
If condition, i.e. percent of call completed reaches 98%.
The data being only used for due to IP bearer network between the equipment and terminal in transmission flexible exchanging network, the IP bearer network
Not through the switching equipment in flexible exchanging network, therefore, refering to the detection shown in Fig. 4 a, using emulator to IP bearer network
Cheng Zhong, data transfer path are the first emulator, CE, IP bearer network, CE, the second emulator.
By adopting the above technical scheme, when the second emulator determines that there are any one network quality parameters values to be unsatisfactory for default item
When part, communication process is kept, avoids caused talking link road when different time in communication network and terminal location difference
It is more accurate to the positioning of fault point by table different problems, improve the accuracy of network quality testing result.
In the embodiment of the present invention, the second emulator obtains flexible exchanging network according to the network quality parameters of flexible exchanging network
Network quality testing result, specifically: the second emulator is by above-mentioned network quality parameters and local default when determining described the
There are any one network quality parameters values not to meet and this in one network quality parameters group or the second network quality parameters group
When the corresponding preset condition of a network quality parameters value of anticipating, the second emulator keeps present communications process；Second emulator according to
The above-mentioned any one network quality parameters value for being unsatisfactory for preset condition, determines network quality fault point and network optimization scheme.
Wherein, joined according to the method that network quality parameters value determines network quality fault point and network optimization scheme according to network quality
The difference of numerical value and it is different, for example, in flexible exchanging network, due to the first emulator and the second emulator respectively correspond it is respective
Therefore a set of IP address when detecting that packet loss phenomenon occurs in measurement equipment MGW to be checked, judges whether with focusing on the same IP
Location, if it is determined that focusing on the same IP address, it is determined that network quality fault point is the MGW, if it is determined that not focusing on same
IP address is then further detected (VPN_RTP detection).In above process, network quality parameters are percent of call completed, single-pass
Rate, noiseless rate, packet loss etc.；Above-mentioned preset condition presets acquisition by user for specific network condition.
Since flexible exchanging network includes various communication equipments, the communication between terminal and terminal is set by above-mentioned communication
Standby, which is measurement equipment to be checked, therefore, refering to the detection shown in Fig. 4 b, using emulator to software switching network
Cheng Zhong, data transfer path are the first emulator, CE, IP bearer network, CE, measurement equipment to be checked, the second emulator.
