Optionally, second simulator is according to comparative result and the first final data bag, obtain the network quality parameters of IP bearer network, be specially: the second simulator is according to above-mentioned first final data bag, adopt voice quality estimation algorithm, obtain the first network mass parameter group of IP bearer network, wherein, this first network mass parameter group is the parameter sets for characterizing operation layer network quality, it comprises multinomial first network mass parameter, such as, first network mass parameter is the MOS(Mean Opinion Score of IP bearer network; Average suggestion value) etc.; After above-mentioned first final data bag and normal data bag compare by the second simulator, obtain comparative result, according to comparative result, obtain the second network mass parameter group of IP bearer network, wherein, this second network mass parameter group is the parameter sets for characterizing network layer network quality, it comprises multinomial second network mass parameter, and such as, second network mass parameter is the IP matching addresses rate of IP bearer network, the packet loss of IP bearer network, the network delay etc. of IP bearer network.
Further, above are only the network quality parameters obtaining any position in IP bearer network, and due in IP bearer network, if the first simulator or the second simulator present position difference, link in then applied IP bearer network is different, therefore, in order to reach the test to whole IP bearer network, after the second simulator obtains the network quality parameters of the IP bearer network current location that the first simulator and the second simulator are determined jointly, change the position of the first simulator or the second simulator, namely IP bearer network link to be detected is changed, still adopt above-mentioned network quality parameters obtain manner, obtain the network quality parameters of different link in IP bearer network, until all links are all detected complete in whole IP bearer network.Optionally, the position of above-mentioned first simulator and the position of the second simulator can pre-set according to equipment facilities in concrete IP bearer network and obtain.
Adopt technique scheme, simulate two terminals respectively by the first simulator and the second simulator, need not network quality checkout equipment in a large number, thus effectively reduce the cost of IP bearer network network quality detection; Further, achieve the real simulation of network service process end to end by the Signalling exchange between two simulators, improve the accuracy of the network quality parameters of acquisition.
Step 210: the second simulator receives by the normal data bag after the coding of device forwards to be detected, the second final data bag is generated after being decoded by normal data bag after this coding, and the normal data bag that this second final data bag and the second simulator this locality are preserved is compared, and according to above-mentioned second final data bag and comparative result, obtain the network quality parameters of flexible exchanging network.
In the embodiment of the present invention, the first simulator is sent to the second simulator according to preset data transmission rate by IP bearer network after adopting AMR2 coding to normal data bag; In default time delay range, when the second simulator receives the normal data bag after the coding that the first simulator sent by IP bearer network, AMR2 decoding is adopted to the normal data bag after this coding, generates the second final data bag.Wherein, in order to ensure the accuracy of network quality testing result, in above process, the normal data bag that the first simulator sends is the packet that standard agreement specifies.
Optionally, second simulator is according to comparative result and the second final data bag, obtain the network quality parameters of flexible exchanging network, be specially: the second simulator is according to above-mentioned second final data bag, adopt voice quality estimation algorithm, obtain the first network mass parameter group of current equipment to be detected, wherein, this first network mass parameter group is the parameter sets for characterizing operation layer network quality, it comprises multinomial first network mass parameter, such as, first network mass parameter is the MOS value etc. of current equipment to be detected; After above-mentioned second final data bag and normal data bag compare by the second simulator, obtain comparative result, according to comparative result, obtain the second network mass parameter group of current equipment to be detected, wherein, this second network mass parameter group is the parameter sets for characterizing network layer network quality, it comprises multinomial second network mass parameter, such as, second network mass parameter is the packet loss of flexible exchanging network, network delay etc.
Further, above are only the network quality parameters obtaining an equipment to be detected in flexible exchanging network, and owing to being made up of large number quipments in flexible exchanging network, the function that is different or that realize of link residing for distinct device is different, therefore, after the network quality parameters completing above-mentioned current equipment to be detected obtains, to other checkout equipments in flexible exchanging network except current equipment to be detected according to above-mentioned network quality parameters acquisition methods, obtain the network quality parameters of all equipment to be detected in flexible exchanging network, thus reach the object detecting whole flexible exchanging network.Wherein, optionally, after to current equipment Inspection to be detected, by obtaining the topological diagram of all devices in flexible exchanging network, next equipment to be detected can be obtained by topological diagram, by that analogy, until all devices all detects complete in topological diagram, namely represent that flexible exchanging network detects complete.
Consult shown in Fig. 3, for the first simulator, the second simulator in flexible exchanging network testing process in the embodiment of the present invention, and the Signalling exchange schematic diagram between equipment to be detected, wherein, signaling when software switching network detects between each equipment is the signaling that agreement specifies.Such as, IAM(Initial address, initial address), APM(Application Transport Mechanism; Application transport mechanism), ACM(AddressComplete Message, Address Complete Message), ANM(Answer Message, response message) transmission by IBCC(Bearer Independent Call Control protocol; With the call control protocol that carrying is irrelevant) signaling that specifies realizes; The transmission of routing iinformation is by MAP(Mobile Application Part; MAP) realize; Initial message (Initialization), initialization answer message (AcknowledgeInitialization) are by IuUP(Iu Interface User Plane Protocols; The wireless network layer user surface agreement of Iu interface) signaling that specifies realizes.
Adopt technique scheme, simulate two terminals respectively by the first simulator and the second simulator, need not network quality checkout equipment in a large number, thus effectively reduce the cost of the network quality detection of flexible exchanging network; Further, achieve the real simulation of network service process end to end by the Signalling exchange between two simulators, improve the accuracy of the network quality parameters of acquisition.
In the embodiment of the present invention, above-mentioned steps 200 and step 210 be order in no particular order, first can perform step 200, then performs step 210; Also first can perform step 210, then perform step 200.
