Fig. 6 is the flow chart according to support MTP3 of the present invention and M3UA routing check method of testing.As shown in Figure 6, this method may further comprise the steps:
S602, when receiving the MRVT request, the MRVT processing module is judged the transmit leg of MRVT request;
S604 if the transmit leg of MRVT request is a local network management, then judges relevant MTP3 or M3UA route that whether destination signaling point can reach and whether have destination signaling point, if each then carries out S612 for what negate in the above-mentioned judged result;
S606, if the transmit leg of MRVT request is other signalling points, judge then whether current signalling point is whether the destination signaling point of MRVT, current signalling point are Signalling Transfer Points, whether have the overlength route, whether can discern MTP3 route or M3UA route that whether transmit leg, destination signaling point can reach, whether current signalling point has disposed destination signaling point that MRVT asks, if each then carries out S612 for what negate in the above-mentioned judged result;
S608 travels through all relevant MTP3 and M3UA route and sends the MRVT request;
S610 is provided with timer, and waits for that in the timing of timer the MRVT that MTP3 that all are relevant and M3UA route are returned replys; And
S612 judges the transmit leg of MRVT request once more, if local network management then replys all MRVT and comprehensively return to local network management, comprehensively returns to other signalling points otherwise all MRVT are replied.
Wherein,, then represent the routing check failure, directly return the MRVT failure and reply to local network management if destination signaling point is unreachable or do not have the relevant MTP3 or the M3UA route of current signalling point to destination signaling point.
Handle below carrying out in S608: all MTP3 routes that traversal can reach destination signaling point send the MRVT request; And send MRVT request about destination signaling point to the next node of each MTP3 route.
Further, also handle below the execution in S608: all M3UA routes that traversal can reach destination signaling point send MRVT request; And send MRVT request about destination signaling point to the next node of each M3UA route.
Handle below carrying out in S610: timer is replied in the test that each MTP3 or M3UA route are set; And judge whether in the timing of timer is replied in test, to receive that the test of MTP3 or M3UA route replys.
Also carry out following the processing in S610: if less than receiving in the timing of replying timer in test that the test of MTP3 or M3UA route replys, then this route of mark is received negative response.
Wherein, if the transmit leg of MRVT request is a local network management, then in S612, carry out following processing: gather all tests and reply and return to local network management; And local network management replys the network topology that is generated to destination signaling point according to test, and according to network topology the user shown.
If the transmit leg of MRVT request is other signalling points, then in S612, carry out following processing: gather all tests and reply and return to other signalling points.
Wherein, network topology is the network topology about the combination of MTP3 route or M3UA route or MTP3 route and M3UA route.
Fig. 7 is the process chart according to the support MTP3 of the embodiment of the invention and M3UA routing check method of testing.As shown in Figure 7, utilize the MRVT processing modules implement specifically to may further comprise the steps for the routing check test processing method of MTP3 route and M3UA route.
Step S702 receives that MRVT request judgement request afterwards still is that other signalling points send over from local network management.If local network management, then MRVT is local the initiation, need at last to reply test result to webmaster, carry out S704, if other signalling points send to the check test request of this signalling point, then local the needs further tests and replys demand signalling point from test result to MRVT and initial signalling point, carries out S706.
Step S704 is divided into two following step S704A, S704B:
S704A judges at first whether the destination signaling point of MRVT can reach, and carries out S704B if can reach then continue, and carries out S712 if signalling point is unreachable and directly replys test result to webmaster: and
S704B, continue to judge whether this signalling point has disposed the MTP3 route or the M3UA route of the destination signaling point of MRVT, if do not dispose any MTP3 route or M3UA route then carry out S712 and directly reply test result, otherwise carry out S708 and on relevant route, send the MRVT test post to webmaster.
Step S706 is divided into six following step S706A, S706B, and S706C, S706D, S706E, S706F:
S706A, judge whether local signaling point is the destination signaling point of MRVT, if words then carry out S714 and carry out relevant replying with initial signalling point to the initiation signalling point of MRVT, if not words need carry out the dependence test that S706B continues to be initiated in this locality destination signaling point;
S706B, judge whether this signalling point is STP, if the destination signaling point of MRVT be not this signalling point simultaneously this signalling point be not again that STP need carry out S714 and carries out relevant replying to the initiation signalling point of MRVT with initial signalling point, otherwise continue execution in step S706C;
S706C, judge whether to exist the overlength route, when the initiation signalling point of MRVT after the signalling point of this signalling point process has surpassed corresponding thresholding, think and have the overlength route, carry out S714 and carry out relevant replying with initial signalling point to the initiation signalling point of MRVT, the purpose of this judgement is for the route of checking that the road that whether has overlength in the network has or circulates, otherwise continues execution in step S706D;
S706D judges whether to discern the initial signalling point of MRVT, if can not carry out S714 to replying that the initiation signalling point of MRVT is correlated with, otherwise continues execution in step S706E;
S706E judges whether the destination signaling point of MRVT test can reach, and carries out S706F if can reach then continue, and carries out S714 if signalling point is unreachable and carries out relevant replying to the initiation signalling point of MRVT with initial signalling point; And
S706F, judge that this signalling point has disposed the MTP3 route or the M3UA route of the destination signaling point of MRVT, if do not dispose any MTP3 route or M3UA route then carry out S714 and carry out relevant replying with initial signalling point, otherwise carry out S708 and on relevant route, send the MRVT test post to the initiation signalling point of MRVT.
Step S708 is divided into four following step S708A, S708B, and S708C, S708D:
S708A traverses the available MTP3 route of MRVT destination signaling point, sends about the MRVT message of destination signaling point and to the timer of the test setting wait acknowledge of this route, execution in step S708B after traversal is finished to the next node of MTP3 route;
S708B traverses the available M3UA route of MRVT test purpose signalling point, sends about the MRVT message of destination signaling point and to the timer of the test setting wait acknowledge of this route, traversal is finished back execution S708C to the next node of M3UA route;
S708C, all relevant MTP3 routes and M3UA route send MRVT finish after relevant the replying of wait, if for particular way by test do not receive yet then at waiting timer and reply then handle according to negative response, node on receiving a certain MTP3 route or M3UA route send return reply after, carry out S708D and judge; And
S708D judges whether the MRVT message that sends on all MTP3 routes and the M3UA route has all been received to reply (or relevant waiting timer then), if having the test request of replying or not then return S708C and proceed to wait for; Otherwise execution in step E gathers all tests to be replied.
Step S710, judge that this MRVT comes from local network management and initiated by this locality or come from other signalling points in the network, if testing to local network management, the local then execution S712 that initiates replys, if come other signalling points in the automatic network then to reply to it.
Step S712, if MRVT is initiated by this locality, then be generated to the network topology of destination signaling point according to the test result on each MTP3 route and the M3UA route, this network topology may have only the MTP3 route, may have only the M3UA route, also may have MTP3 route and M3UA route simultaneously.Webmaster is correlated with to user's demonstration according to network topology.
Step S714, if being other signalling points in the network, MRVT initiates, then the initiation signalling point of MRVT is replied, in the time of the destination signaling point of this locality MRVT, also need directly to replying that the test of MRVT initiates that signalling point is correlated with according to the test result on each MTP3 route and the M3UA route.
In sum, by method of the present invention, can realize when the check test function a when destination signaling point exists MTP3 and M3UA route simultaneously.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
