When alarm takes place, can learn network element that this alarm takes place, transmission system, integrated circuit board, port, transmission time slot etc. from warning position information (with reference to table 2), network element, transmission system, integrated circuit board obtain according to port, the time slot of alarm generation.By these information search circuit routing iinformation (referring to table 3, table 4) in resource database, the circuit name that just can obtain process on the alarm generation equipment reaches for information about.
Because on the network element that alarm takes place, transmission system, integrated circuit board, port, may have many circuit route processes, therefore when on the alarm generation equipment during through too much bar circuit route, many circuit of this alarm and this all might be relevant, do not have the circuit route through out-of-date on alarm generation equipment, this alarm is just not relevant with any circuit.
Step S204: the positional information that alarm takes place according to described fault feature is determined the fault judgment rule that will use and is judged, when fault feature alarm and fault feature are alarmed the circuit information that is influenced and met described fault judgment rule, determine that this circuit breaks down.
Obtaining of judgment rule is to obtain different rules according to the position difference that alarm takes place.Alarm occurs on the port of circuit, need obtain the judgment rule on the circuit port in judgment rule.Alarm occurs on the time slot, need obtain the judgment rule of circuit time slot.
Step S205: generate the indication information that comprises warning information that influences fault and the circuit information that breaks down, and present to the user.
The information spinner that presents will comprise the circuit information that fault takes place, the warning information on this circuit etc., and the attendant just can in time find fault by these information, and carries out maintenance work fast, ensures the normal operation of transmission network.
Based on the said method flow process, as shown in Figure 3, how to alarm positional information and the definite fault judgment rule that is suitable for that takes place according to described fault feature in order to explanation, and the finally generation of definite fault.
Step S2041: the positional information that from step S2031, obtains the alarm of fault feature, when the positional information of fault feature alarm generation is tributary port, enter fault judgment rule one step S2042, when the positional information of fault feature alarm generation is transmission time slot, enter fault judgment rule two step S2043 to step S2046.
Step S2042: directly determine this circuit generation fault according to the alarm of fault feature, draw the fault result, finish.
Tributary port is the port of upstream and downstream business; it is the least significant end of institute's bearer service; loaded service on tributary port; not having the protection route protects it; the alarm of fault feature has taken place on the tributary port; must be the circuit of process break down, therefore can be directly according to the fault feature alarm judge circuit and break down.
For example produce alarms such as LOS, TP-AIS or LOF at tributary port, all can directly judge the circuit of process break down.
Step S2043: the protected mode that obtains the transmission system that circuit passes through in the relevant circuit information of fault feature alarm.
The transmission time slot of SDH circuit is one of granularity of built-up circuit route; in order to guarantee the normal operation of circuit; usually can take some safeguard measures to these transmission time slots; when the primary route of circuit breaks down; can moment with professional auto switching on the protection route of circuit; circuit also is in normal operating condition, so just can avoid the circuit catastrophic failure to cause professional the stagnation, for the fault on the repaired circuit primary route provides the time assurance.
The protected mode of transmission system that circuit passes through has two kinds, and one is the multiplex section protection mode, and two is the path protection mode.
Step S2044: primary route and the protection route of determining described circuit according to the protected mode of transmission system that circuit passes through.
Circuit in transmission system, according to the protected mode difference of transmission system, primary route and the alternate routing of in store circuit in this transmission system in the resource database of system.
According to the protected mode of the transmission system that circuit passes through in the circuit information, can determine that this circuit is multiplex section protection mode or path protection mode.Attribute by the retrieval transmission system obtains protected mode, and the protected mode of this transmission system is arranged in the attribute of transmission system.
For the multiplex section protection mode, be meant that when fault takes place the operating position according to multiplex section in the net calculates current available route, use as the protection route, be illustrated in figure 4 as the routing switch of two fibre two-way multi-section guard rings.
Network element A is placed on the S1 time slot of S1/P2 optical fiber to the working traffic of network element C among Fig. 4 a, and standby business is put in the P2 time slot, passes to network element C along optical fiber S1/P2 by network element B break-through, and network element C extracts main with, extra traffic respectively from S1, P2 time slot on the S1/P2 optical fiber.Network element C is put in the S2 time slot of S2/P1 optical fiber to the working traffic of network element A, and extra traffic is put in the P1 time slot of S2/P1 optical fiber, passes to network element A through network element B break-through, and network element A extracts corresponding business from S2/P1 optical fiber.
When optical cable segment is cut off between looped network B-C among Fig. 4 b, network element A passes to network element B to the working traffic of network element C along S1/P2 optical fiber, carry out loopback (fault end points place loopback) at network element B place, loopback is the business of S1 time slot on the S1/P2 optical fiber all to be encircled on the P1 time slot on the S2/P1 optical fiber go, and the extra traffic on this moment S2/P1 optical fiber P1 time slot is interrupted.Pass to network element C along S2/P1 optical fiber through network element A, network element D break-through then, carry out loop fuction (fault end points station) at network element C, soon the contained network element A of P1 time slot on the S2/P1 optical fiber is looped back to the S1 time slot of S1/P2 to the working traffic of network element C, network element C extracts the business of this time slot, finishes to receive the working traffic of network element A to network element C.Equally, network element C to network element A professional earlier by network element C with the working traffic S2 of network element C to network element A, be looped back on the P2 time slot of S1/P2 optical fiber the interruption of the extra traffic on the P2 time slot at this moment.Arrive network element B along S1/P2 optical fiber through network element D, network element A break-through then, carry out loop fuction at network element B place--the P2 time slot services ring of S1/P2 optical fiber is gone to the S2 time slot of S2/P1 optical fiber, pass to network element A through S2/P1 optical fiber.
For the path protection mode, the protection route segment is just reserved out when the design circuit route, and the protection route segment information in the circuit information in the therefore direct retrieve resources database just can obtain.
Step S2045:, obtain the primary route of described circuit and the fault feature alarm on the protection route by the related information of alarm of search circuit fault signature and circuit route.
Generation alarm equipment information in the alarm of fault feature and the relevant relation of port information in the circuit route, produce on the alarm equipment (just port, integrated circuit board, time slot, equipment etc.) to have passed through which circuit by retrieval, thereby obtain the circuit that alarm is influenced; By search circuit produced which alarm on the equipment of process, from these alarms, filter out the alarm of fault feature again, thereby determine the primary route of circuit and the fault feature alarm on the protection route.
Step S2046: when having the alarm of fault feature simultaneously on the primary route of described circuit and the protection route, determine that circuit breaks down, draw the fault result, finish.
When the circuit primary route generation fault of multiplex section protection mode, system can protect automatically and switch, switch the business on the protection route of circuit, and the moment alarm of going up the fault feature alarm on the telegraph circuit primary route and protecting routing switch to cause, when switching successfully, switch the moment alarm that causes and disappear, professional normally operation on the circuit protection route; When also fault taking place on the protection route of circuit, system can report the fault feature alarm on the circuit protection route, because this moment, the circuit primary route broke down, business can't normally be moved, and determines that fault has taken place circuit.
For example, the circuit of multiplex section protection mode, equipment time slot produce the TU-AIS alarm, direct decision circuitry fault, and system protects when switching automatically, and the corresponding TU-AIS of route that protects can produce instantaneous alarm, switches successfully, and this alarms disappearance; Be user mode for example again for the protection route; have only and when working time slot fault feature alarm (as AU-AIS) all occurs with the protection time slot, just be judged as fault; fault feature alarm (as AU-AIS) to folk prescription produces is not judged as fault.
When the circuit primary route of path protection mode with the protection route alarm of fault feature takes place simultaneously all, determine this circuit generation fault.
In order better to set forth the present invention, provide embodiment two in conjunction with actual conditions and be illustrated.
Article one, speed is the circuit of 2M, and the network of process is shown in Fig. 5 a, and the 2M circuit is from NE1 to NE4, and is middle through NE2.
The time slot of process is NE1/9-SL16/1/155M1/2M1, NE2/10-SL16/1/155M1/2M1, NE2/9-SL16/1/155M1/2M1, NE4/10-SL16/1/155M1/2M1
Obtain the warning information on the transmission network, as shown in table 5:
Table 5
| Alarm name | Warning position |
| ??T_ALOS | ??NE1/9-SL16/1 |
| ??TU_AIS | ??NE2/9-SL16/1/155M3/2M5 |
| ??MS16cAIS | ??NE31/2/L16.1/1 |
| Alarm name | Warning position |
| ??AU_AIS | ??NE3/10-SL16/1/155M4 |
Through with the comparison of fault feature alarm name tabulation, filter out alarm T_ALOS, TU_AIS, AU_AIS is the alarm of fault feature, and alarm MS16cAIS is not the alarm of fault feature, therefore it is not made judgement.
Search circuit NE1 is to the circuit information of NE4 in resource database, and is as shown in table 6:
Table 6
| Circuit name | The NE1-NE2 route segment | The NE2-NE4 | Encircle | 1 protected mode |
| ??NE1-NE4?2M1 | ??155M1/2M1 | ?155M1/2M1 | Two fibre two-way multi-section guard rings | |
| A holds port | Z holds port | | Encircle | 1 speed |
| ??NE1/9-SL16/1 | ??NE4/10-SL16/1 | ?2M | ??2.5G | |
| Equipment producer | Signal type | |||
| Huawei | ??SDH |
The positional information that obtains alarm T_ALOS, TU_AIS, AU_AIS is respectively NE1/9-SL16/1, NE2/9-SL16/1/155M3/2M5, NE3/10-SL16/1/155M4, A ports port information in the circuit information is NE1/9-SL16/1, the positional information that takes place with alarm T_ALOS is identical, so both have incidence relation, judges that the alarm circuit that T_ALOS influenced is NE1-NE3 2M1, and therefore alarm TU_AIS, AU_AIS do not make judgement all less than the circuit information of influence.
Because port NE1/9-SL16/1 is the A end port of circuit, by the retrieve resources database, obtaining port attribute information is tributary port.The implication of NE1/9-SL16/1 is: NE1 is an element name; 9-SL16 is network element 9 groove positions, and what insert on this groove position is the such device board of SL16; The 1st, first port of 9-SL16.
According to fault judgment rule one " take place on the tributary port that the alarm of fault feature circuit can directly be drawn break down ", determine that circuit NE1-NE4 2M1 breaks down.
