Description
Technical field
The present invention relates to the Time synchronization technique in mobile communications network, more particularly to a kind of time synchronized performance monitoring side
Method, apparatus and system.
Background technology
The support of the development need simultaneous techniques of mobile communications network, in the mobile communication network, the stabilization of carrier frequency,
Being aligned of uplink and downlink timeslot, the transmission of reliable high quality, base station equipment between switching and roaming etc. be required to it is accurate
Time synchronized control.For the mobile communications network based on TDMA or CDMA, except frequency
, it is necessary to the up to exact time synchronization of Microsecond grade outside synchronization.
In order to meet the high-precision time synchronized demand of equipment in mobile communications network, it can use and be set on each base station
Put global positioning system（GPS）Satellite time transfer module solves.Except when setting gps satellite time service module on base station to carry out
Between outside synchronous mode, time synchronized can also be realized by settling time synchronizing network in the mobile communication network, be specially：When
Between provide time source in upstream equipment in synchronizing network, time source sent to based on time transportation protocol upstream equipment each
Equipment uses, as shown in figure 1, Fig. 1 is the structural representation of the Time Synchronization Network of prior art.In this way by the time
In upstream equipment in set of convergence, the equipment of each such as base station in downstream obtains the time from upstream equipment, effectively reduces setting in source
It is equipped with the number of devices of gps satellite time service module and each equipment sets the installation difficulty of gps satellite authorization module.Fig. 1
In the time transportation protocol that is based on be IEEE1588v2 Precision Time Protocol（PTP, Precission Time Protocol）,
Precision can reach submicrosecond rank.IEEE1588v2PTP is principal and subordinate's time type time synchronization protocol, and main equipment provides the time
Source, for slave unit, such as base station carries out time synchronized.Intercommunication time message message between main equipment and slave unit, slave unit root
The time source provided according to main equipment corrects its temporal.
Specifically, the principle of Time Synchronization Network progress time synchronized is：Main equipment and slave unit use are such as synchronous
（Sync）Message, tracking（Follow_Up）Message, delay request（Delay_Req）Message and delay respond（Delay_Resp）
The time message such as message message mutually notices accurate timestamp, passes through optimal clock algorithm（BMC, Best Master Clock
Algorithm）Optimal clock source is selected, the deadline is synchronous.
Herein, slave unit is each equipment to carry out time synchronized, for example can be base station, transmission equipment etc.,
Here do not limit.
Fig. 2 is the method for synchronizing time flow chart in prior art Time Synchronization Network, and it is concretely comprised the following steps：
The picture transfer protocol of step 201, main equipment（PTP）Application layer sends synchronization message to slave unit, and main equipment is same
When recording synchronism message leave the precise time t1 of PTP application layers port；
Step 202, slave unit receive synchronization message, recording synchronism message receipt times t2, while report slave unit
PTP application layers；
Step 203, the PTP application layers of main equipment send tracking message to slave unit, and message carries synchronization message and leaves PTP
The precise time t1 of application layer port；
After step 204, slave unit receive the tracking message, precise time of the recording synchronism message from PTP application layers port
t1；
After this step, slave unit can learn the precise time t1 that synchronization message is sent, and receive lock in time t2；
Step 205, the PTP application layers of slave unit send delay request message to main equipment, and slave unit records the delay and disappeared
Breath leaves the time t3 of PTP application layers port；
Step 206, main equipment record receive the time t4 of the delay request message, are somebody's turn to do reception by postponing response message
The time t4 of delay request message is sent to slave unit.
After above-mentioned steps, formula can be obtained（1）And formula（2）：
The reporting of time difference=slave unit between master-slave equipment+master-slave equipment transmission message delay value=t2-t1；Formula
（1）
From time difference between main equipment=from reporting=t4-t3 of master transmissions message delay value-slave unit
Formula（2）
Assuming that master-slave equipment transmission message delay value is identical with from master transmissions message delay value, then can in slave unit
To draw：The reporting of slave unit=（（t2-t1）-（t4-t3））/2
Length of delay=（（t4-t3）+（t2-t1））/2
So, slave unit compensates the local zone time of slave unit according to the reporting of slave unit, realizes slave unit and master
The time synchronized of equipment.
When using lock in time network as equipment progress time synchronized, Time Synchronization Network is that mobile communication business is normally transported
Capable basis, the penalty of time synchronized will directly influence the operation of mobile communication business.In order to supervise and safeguard synchronization
The operation conditions of time network is, it is necessary to carry out the monitoring of time synchronized performance.
But at present in lock in time network, lack the monitoring method to time synchronized performance.Due to time synchronization network
Equipment in network does not have accurate time source to be referred to as monitoring, thus can not monitor that equipment carries out lock in time source whether
Accurately, whether can only can be normally received by such as time message message, if the packet loss of existence time message, and
The time synchronized module set in equipment whether the indirect means such as normal work determine lock in time network whether normal operation, but
The time synchronized performance of each equipment in lock in time network can not specifically be judged.

9. system as claimed in claim 8, it is characterised in that the management entity also includes：
Data Collection memory module, for cache-time deviation and length of delay, multiple times are cached with cache-time section
Deviation and length of delay；
Time performance computation analysis module, for calculating the time deviation wobble variation value in setting time section, and calculate setting
Delay jitter changing value in period, determines whether time deviation wobble variation value exceedes the time deviation wobble variation set
Threshold value, and determine whether delay jitter changing value exceedes the delay jitter change threshold set, if one of them exceedes, it is determined that
Time synchronized performance declines, and sends an indication to performance alarm module, otherwise, terminates；
Performance alarm module, for time deviation wobble variation value to be excessive according to corresponding to instruction progress or/and delay jitter becomes
Change is worth excessive alarm.
10. system as claimed in claim 9, it is characterised in that in the management entity, time performance computation analysis module,
The no reporting threshold value for exceeding setting of absolute value that determination is reporting is additionally operable to, if it is, determining that the time is same
Hydraulic performance decline is walked, sends an indication to performance alarm module；
Performance alarm module, it is additionally operable to the excessive alarm of reporting corresponding to carrying out.
