Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of PTP (Precision Time Protocol, when accurate
Between agreement) method and device tested automatically of message.
Background technique
In a communication network, perhaps multiple services normal operation requires that network clocking is synchronous, i.e., each equipment of whole network it
Between time or difference on the frequency be maintained in reasonable error level.Such as it is required in the multiple network mode of mobile communication field
Base station meets time synchronization and could work normally between eating dishes without rice or wine, comprising: TD-SCDMA (Time Division-Synchronous
Code Division Multiple Access, TD SDMA), TD-LTE (Time Division Long
Term Evolution, timesharing long term evolution), CDMA2000 (Code Division Multiple Access 2000),
LTE-A (LTE Advanced), MBMS (multimedia broadcast/multicast service) etc..
PTP is a kind of agreement of time synchronization, itself can be used for the precise synchronization between equipment.At one
In PTP synchronization path, master clock provides source time, synchronous for next stage clock, that is, supplies from clock reference.Then lead to from clock
It crosses with master clock intercommunication message, the time adjustment local zone time provided according to master clock.
Referring to Fig. 1, for PTP message interaction flow chart in the prior art.PTP is related to a variety of PTP messages, comprising: when interaction
Between stab synchronization (Sync) message, latency request (Delay_Req) message, delay respond (Delay_Resp) message and carry when
Between state notice (Announce) message.The specific value and real network phase that each field of PTP message is filled in application
It closes, therefore does not make specific definition in IEEE.
It is different network systems since when realizing PTP function, each field filling numerical value has differences PTP relevant device
Intercommunication with equipment causes certain difficulty.In order to preferably realize device intercommunicating, it is necessary to which proposition can accurately and effectively judge
The scheme of the interworking case of PTP message.
Summary of the invention
In view of the above problems, the present invention is proposed in order to provide a kind of method and device that PTP message is tested automatically, it can be with

Second to the PTP message received sends frequency；
Second comparison module, for by the hair of the first PTP message corresponding with the type of message of PTP message received
Frequency is sent, is compared with the second transmission frequency of the PTP message received；
Second output module, if for inconsistent, the transmission frequency problematic second of the PTP message received described in return
Test result.
9. device as claimed in claim 7, which is characterized in that described device further include:

The transmission frequency of segment value and the Delay_Resp message；
Third comparison module, the field for the logMessageInterval field that the Delay_Resp message for that will send carries
The transmission frequency of value and the Delay_Resp message, the practical transmission with the Delay_Req message for being devices under transmission
Frequency and the field value of logMessageInterval field of Delay_Req message for being devices under transmission are compared
It is right；
Third output module, if returning to Delay_Resp message for inconsistent and sending the problematic third test knot of frequency
Fruit.
10. device as claimed in claim 7, which is characterized in that described device further include:
Module is adjusted, the numberical range of the transmission frequency of the PTP message of the various type of messages of storage is preset for basis,
Adjust the transmission frequency of the PTP message issued；
4th output module, if for not receiving the PTP message for being devices under the sending of reply in the given time
Response message, then return described in be devices under support PTP message problematic 4th test result of transmission frequency.
11. device as claimed in claim 7, which is characterized in that described device further include:
Third logging modle, for recording the timestamp information of the PTP message received；
5th output module, if being that negative value or timestamp information are less than the PTP report received for the timestamp information
The timestamp information of the previous message of text, then the 5th test of the timestamp information mistake of the PTP message received described in return
As a result.
