Fig. 2 is the network implementation structure chart of mobile service monitoring system.
Fig. 3 is the schematic flow sheet of method of testing of the present invention.
Embodiment
Now, describe a preferred embodiment of the present invention in detail in conjunction with Figure of description.
Shown in Figure 2, mobile service monitoring system (being relaying type auto-dial testing system) is as test center, this mobile service monitoring system by with core net in signaling, traffic net direct-connected, simulation MSC/VLR function, realize professional emulation testing, as switch and circuit test, virtual net operational trials, Familiarity Number test, Ring Back Tone service test, short message service test etc.The tester is after the mobile service monitoring system is assigned test assignment, and system adopts the IAM message among the Signaling System Number 7 BICC to make a call, and concrete method of testing is as follows, referring to Fig. 1:
Pre-conditioned: suppose that professional monitoring system switch is numbered 999, SSA3 is numbered 187, and Hangzhou GS8 is numbered 108; Test caller: 17242001; Test called: 17240108187999.
Test route: mobile service monitoring system → soft switch A office (Hangzhou SSA3) → Hangzhou GS8 → soft switch A office (Hangzhou SSA3) → mobile service monitoring system (loopback).
Concrete steps: professional monitoring system makes a call and gives soft switch A office (Hangzhou SSA3), and caller is 17242001, and called is 17240108187999; SSA3 analyzes called prefix 17240 back 3 switches codings 108, and it be Hangzhou GS8 that inquiry obtains 108, then with after 108 removals of these 3 codings, with calling give Hangzhou GS8 (caller: 17242001, called: 17240187999); After Hangzhou GS8 receives calling, analyze back 3 switches coding 187 of called prefix 17240 equally, it be Hangzhou SSA3 that inquiry obtains 187, then with after 187 removals of these 3 codings, with calling give Hangzhou SSA3 (caller: 17242001, called: 17240999); SSA3 analyzes called prefix 17240 back 3 switches codings 999, and it be the mobile service monitoring system that inquiry obtains 999, then with after 999 removals of these 3 codings, with calling give the mobile service monitoring system (caller: 17242001, called: 17240); Call out and form loopback; BICC enters talking state after calling out loopback, sets up the RTP test channel simultaneously, two-way transmission RTP test pack; According to the RTP test pack of transmitting-receiving, situations such as time delay, packet loss, shake and voice quality under this route of statistical analysis.
As shown in Figure 3, monitoring IP bearer network quality test step of the present invention mainly by the customization test assignment, initiate test, set up the RTP test channel and send test pack, statistical analysis RTP test pack, form five steps such as IP bearer network quality report and form.Five step operations independently connect each other again.1) customization test assignment.Mainly be that the mode by artificial interpolation task is carried out on the mobile service monitoring system, selected different test mode, test number, executive mode and time etc., form test assignment; 2) initiate test.System initiates test by tandem exchange, according to the route of appointment, according to the synthetic called number of switch code set, makes a call by the BICC signaling, and is looped back to professional distributed-network monitoring platform automatically; 3) set up the RTP test channel and send test pack.System enters talking state after calling out loopback by BICC, sets up the RTP test channel simultaneously, two-way transmission RTP test pack; 4) statistical analysis RTP test pack.According to the RTP test pack of transmitting-receiving, situations such as time delay, packet loss, shake and voice quality under this route of statistical analysis; 5) form IP bearer network quality report.According to the situation that statistical analysis RTP test pack obtains, gather the result of each test assignment, form report.
Hardware syndeton shown in Figure 1 is carried out a large amount of testings, and the each test of record RTP bag " sending the time " reach " time of receipt (T of R) ", test this channel network time delay, packet loss, shake and voice quality etc. by RTP emulation communication process.
Described method of testing can be monitored all network link performance of carrying soft switch end office (EO) Media Stream, comprises terminal link; Be applicable to the Softswitch of all kinds of employing BICC signalings; Can travel through test to the whole network network element, be used to monitor each network element, whether each node device catastrophe failure occurs.When finding that in test process certain office direction or some office direction monitoring parameter are unusual, system judges it is which node or which bar link break down fast by recurrence stack test.The network test order is assigned as Ping, LSP Ping, VRF Ping, Traceroute, LSP Traceroute, VRF Traceroute etc. by system then, analyzes the investigation malfunctioning node.
Method of testing of the present invention has following technological merit:
1, a bit inserts: utilize the mobile service monitoring system, can accomplish a bit to insert all webs' watch, only need Any point is disposed a probe in net, and by specific algorithm, can be between the whole network any two points Network quality monitor.
2, all standing test: can realize end-to-end the whole network coverage test, not only can be to comprising CE and MGW Between terminal link monitor in the performance of the network link of interior all carryings soft switch end office (EO) Media Streams, Can also travel through test to the whole network network element, whether occur seriously for each network element of monitoring, each node device Fault.
3, calculating is carried out fault fast positioning with the recurrence stacked system based on topology: for the whole network tree type and pattern Network topology structure travels through optimum test path model by single-point and produces test assignment, appoints according to each test Affair result and task test path are located fault network element or fault network fast with the recurrence stacked system.
4, digitize voice quality fast detecting: by sending the VoP of customization tape identification, accurately count Calculate transmission of voice packets time delay, packet loss, the bit error rate, the jitter value of communication process, and in conjunction with the voice document branch Analyse and calculate and quantify speech quality PESQ value.
