Below in conjunction with Figure of description, preferred embodiment of the present invention will be described, it should be understood that described herein
Preferred embodiment only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention, and in the absence of conflict, this hair
The feature in embodiment and embodiment in bright can be combined with each other.
Embodiment one
Inventors have found that synchronization node equipment not will do it alarm in the decline of synchronizing network quality.For example, TD-
It is 1.5us that the base station SCDMA/TD-LTE, which requires the timing tracking accuracy of base station, if the time error between base station is more than this
Limit value, then adjacent base station eats dishes without rice or wine to generate interference and uplink and downlink timeslot interference between time slot, causes user's communication unsuccessful.In order to keep away
Exempt from such case, TD-SCDMA/TD-LTE moves back the mechanism of clothes in base station, and the base station is in certain time if base station loses time source
It inside will move out service, in order to avoid other adjacent base stations are interfered.But when base station obtains synchronizing information by transmission network
When, under existing Synchronize Alarm mechanism, alarm can be just only generated when base station finds drop-out time source, if base station can be from
Transmission network obtains the time, but time precision is more than limit value, and base station will not generate alarm, still will continue to track, make to business
At influence, and warning information of the maintenance personnel due to that can not know the decline of synchronisation source quality, it is unable to judge accurately influence business matter
The root of amount needs to expend a large amount of manpowers and carries out fault location.
In view of this, synchronization node equipment is to tracking the embodiment of the invention provides a kind of synchronizing network alarm method
The credit rating of synchronisation source is monitored, and is accused when the credit rating for finding synchronisation source is lower than preset quality grade threshold
It is alert, decline caused communications network service quality decline to avoid due to homologous credit rating, improves the reliability of synchronizing network,
Guarantee the service quality of communication network.
As shown in Figure 1, it is implementation process diagram of synchronizing network alarm method provided in an embodiment of the present invention, it can be with
The following steps are included:
S11, the credit rating information for obtaining the synchronisation source tracked.
If S12, being judged the synchronizing quality grade of the synchronisation source lower than preset according to the credit rating information
Credit rating threshold value is then alerted.
When it is implemented, synchronization node equipment can obtain the matter of the synchronisation source of tracking according to either type in step S11
Measure class information:
Mode one is obtained from the synchronization source messages received
In this embodiment, step S11 can be according to flow implementation shown in Fig. 2:
S21, the synchronization source messages that the synchronisation source tracked is sent are received, carries the synchronisation source in the synchronous source messages
Credit rating information.
Step S22, the credit rating information of the synchronisation source of tracking is obtained from the synchronous source messages.
Wherein, synchronisation source includes Frequency Synchronization source or time synchronization source.For Frequency Synchronization source, credit rating packet
Include SSM (Synchronization Status Message, Synchronization Status Message).As shown in table 1, which show a kind of possibility
SSM coding and definition.
Table 1
When synchronization node equipment obtains the SSM coding that Frequency Synchronization source carries, such as (Ethernet, which synchronizes, to disappear by ESMC
Cease channel) message extract carry SSM coding.Assuming that preset credit rating threshold value is SSU_A, then when quality of synchronisation source etc.
When grade is optionally greater than SSU_A, synchronization node equipment will not generate alarm;When the credit rating of synchronisation source is SSU_B (according to table
1, at this time 1000) corresponding SSM is encoded to, then synchronization node equipment generates corresponding alarm.
, can be by PTP (accurate clock synchronization protocol) acquisition time source for time synchronization source, credit rating information can
With include PTP carry clockClass, Accuracy, OffsetScaledLogVariance it is one of or several
It is comprehensive.
For example, using PTP carry clockClass as alert credit rating, clockClass value from 0 to 255,
Numerical value is smaller, and credit rating is higher.Assuming that setting credit rating threshold value as clockClass=6, then when the credit rating in the source PTP
When optionally greater than clockClass 6 (specific value≤6 of clockClass), equipment will not generate alarm;When the source PTP
When credit rating clockClass=7, then equipment generates corresponding alarm.Wherein, clockClass refers to clock source rank, determines
The justice rank of clockwork clock source, i.e. credit rating;Accuracy refers to clock precision, defines the essence of clockwork
Accuracy;OffsetScaledLogVariance refers to clock stability, defines the stability of clockwork, is node itself
The assessment of its received clock quality is calculated using Allan deviation.
For using the overall target of the PTP clockClass carried and Accuracy as the credit rating of alarm, it is assumed that
Preset credit rating threshold value is clockClass=6, and Accuracy was 100 nanoseconds, when the credit rating of synchronisation source
ClockClass is lower than 6 (for example, 7) and Accuracy numerical value represents when being greater than for 100 nanosecond, then synchronization node equipment generates
Alarm.
Mode two is obtained from 1PPS+TOD (1Palse per Second Time of Day, pulse per second (PPS) Time of Day) interface
The time synchronization source of tracking.
In this embodiment, credit rating information refers to the correspondingly credit rating information that the interface carries, as taken in TOD
The second pulse signal information of band.
Based on this, in the embodiment of the present invention, the credit rating of the synchronisation source of tracking can be obtained according to process shown in Fig. 3
Information:
S31, the time synchronization source that tracking is obtained from 1PPS+TOD interface.
S32, the second pulse signal information that carrying is obtained from Time of Day TOD.
Embodiment two
When it is implemented, in order to avoid accidentally being alerted as caused by individual mass grade message error, in step s 11,
After if the synchronizing quality grade for the synchronisation source for judging to track according to credit rating information is lower than preset credit rating threshold value,
It is further comprising the steps of before being alerted: to determine that the synchronizing quality grade of the synchronisation source of tracking is lower than the credit rating
The duration of threshold value reaches the first preset duration.
When it is implemented, synchronization node equipment is lower than credit rating threshold value in the credit rating for the synchronisation source for detecting tracking
Reach after certain time (such as M seconds) just report and alarm.It can be missed in this way to avoid since individual mass grade message error causes
Alarm, furthermore, it is possible to avoid generating alarm during normal synchronisation source is switched.Assuming that synchronous source node device can receive
The synchronous source messages that synchronisation source A is sent with synchronisation source B, synchronization node selection of equipment tracks synchronisation source A, when the quality of synchronisation source A
When grade declines, synchronization node device switching to tracking synchronisation source B, in this way, if the credit rating of setting detection synchronisation source is low
When credit rating threshold value reaches certain time length ability report and alarm, within M seconds this period, synchronization node equipment is from synchronization
Source A has been switched to synchronisation source B, if the credit rating of synchronisation source B be it is normal, credit rating information is also under synchronisation source A
Drop has been switched to the normal level of synchronisation source B, and such synchronization node equipment would not report and alarm during switching.In this way, only
It wants management system to receive alarm, the current synchronisation source quality decline of expression synchronization node equipment, and does not synchronize normally
The case where source can switch, that is, the case where needing maintenance personnel to handle.If equipment has normal synchronisation source that can switch tracking,
Alarm will not be generated.
In the embodiment of the present invention, synchronization node equipment is after being alerted, if detecting the same of the synchronisation source of tracking
When walking credit rating higher than preset credit rating threshold value, alarm is eliminated.Preferably, when it is implemented, synchronization node equipment also
It before eliminating alarm, can determine that the synchronizing quality grade of synchronisation source reaches higher than the duration of the credit rating threshold value
Second preset duration, for example, the second preset duration can be set to N seconds.This way it is possible to avoid unstable state is restored, lead
The problem of cause alerts repeatedly.
It should be noted that when it is implemented, the credit rating threshold value of synchronisation source can be preset, for same synchronization
Equipment in network can set identical threshold value, can also set different threshold values.
Preferably, when it is implemented, in step s 11, if judging the synchronization according to the credit rating information
The synchronizing quality grade in source is lower than preset credit rating threshold value, then further comprising the steps of before being alerted:
Step 1: obtaining synchronization hop count information of the synchronisation source of tracking apart from root synchronisation source;And
Step 2: determining that the synchronous hop count information is less than or equal to preset synchronous hop count threshold value.
Wherein, root synchronisation source refers to the top in synchronized tracking path, is generally provided by sync server, in PTP synchronization agreement
In, it is GM (GrandMaster, super master clock) equipment.
Based on this, synchronization node equipment can pass through the synchronization hop count information and matter of the synchronisation source carrying of detecting and tracking simultaneously
Class information is measured, as the condition for generating alarm.The synchronization node equipment model that alarm is generated in synchronizing network can be limited in this way
It encloses, such as the equipment being limited within the certain hop count of root synchronisation source just generates alarm.For example, setting is current to select PTP ginseng
The clockClass in source is examined lower than some credit rating threshold value, and when its synchronization jumping figure value stepsRemoved value carried is 0
Alarm is just generated, then the equipment (its stepsRemoved value is 0) being only connected with GM equipment in network is likely to generate the announcement
Alert, the equipment in network downstream again will not then generate alarm.The distinct device in same synchronizing network is avoided to generate a large amount of identical originals
The alarm of cause, and in this way, Root alarm position can be automatically determined, because the equipment that hop count is 0 is as same
The equipment for walking track path most upstream.
As shown in figure 4, NE1 to NE8 form synchronizing network, track path NE1- > NE2- > NE3- > NE4- > NE5 and
NE1- > NE2- > NE6- > NE7- > NE8, according to track path node hop count, what the reference source that each network element receives carried
StepRemoved value is all different.When the decline of NE1 reference source credit rating, and NE1 is first tracking node
(stepRemoved=0), only NE1 produces alarm, this alarm, which is represented, entirely synchronizes chain in the decline of synchronisation source quality
On first decline nodal information.
In the embodiment of the present invention, synchronization node equipment in addition to the credit rating of the synchronisation source to selected tracking detected with
Outside, the credit rating of other synchronisation sources in synchronisation source list can also be detected, and is detecting other tracking sources
When credit rating is lower than preset credit rating threshold value, it can also be alerted.Based on this, in the embodiment of the present invention, synchronous section
Point device can also obtain the credit rating information of other synchronisation sources in synchronisation source list in addition to the synchronisation source of tracking;And
If judging the synchronizing quality grade of other synchronisation sources lower than the credit rating threshold value according to the credit rating information of acquisition
Then alerted.
For example, synchronization node equipment tracks some frequency source selected according to priority list, and monitor its SSM
Credit rating information generates alarm when its SSM value is lower than threshold value.Further, synchronization node equipment can also be in same
Alarm is generated when the credit rating decline of other synchronisation sources in the list of step source.For example, in frequency source list include 3 can be with
It the Frequency Synchronization source of selection can also be in frequency when synchronization node equipment tracks the Frequency Synchronization source of the first priority
The SSM credit rating information in the Frequency Synchronization source of the second priority is monitored in priority list, is lower than threshold value in its SSM value
When generate alarm.
More preferably, when it is implemented, the credit rating information of other synchronisation sources in synchronisation source list can be set
The alarm level generated when decline, credit rating decline of the alarm level lower than the synchronisation source that synchronization node equipment is tracking
Alarm level.For example, the credit rating of other synchronisation sources in synchronisation source list generates minor alarm when declining, and it is same
Significant alarm is generated when the credit rating decline for the synchronisation source that step node device is tracking.
When it is implemented, for the matter of the credit rating monitoring and the synchronisation source of tracking of other synchronisation sources in synchronisation source list
It is similar to measure grade monitoring process, for example, reaching in the credit rating for monitoring other synchronisation sources lower than preset credit rating threshold value
To after the first preset duration, synchronization node equipment is alerted;If be higher than in the credit rating for monitoring other synchronisation sources etc.
After preset credit rating threshold value reaches the second preset duration, synchronization node equipment eliminates alarm.
In synchronizing network alarm method provided in an embodiment of the present invention, synchronization node equipment is in the synchronization for judging synchronisation source
When credit rating declines, corresponding alarm is generated, moreover, the quality that synchronization node equipment can only to the synchronisation source tracked at present
Grade is alerted, which directly reflects the quality for the synchronisation source that equipment currently tracks, and is grasped convenient for management system
Current synchronizing network quality.Furthermore it is also possible to which reaching certain time by the testing result for setting credit rating just generates announcement
Alert and elimination alarm, it is ensured that the validity and stability of alarm.
Based on the same inventive concept, a kind of synchronizing network alarm device is additionally provided in the embodiment of the present invention, due to above-mentioned
The principle that device solves the problems, such as is similar to synchronizing network alarm method, therefore the implementation of above-mentioned apparatus may refer to the reality of method
