Embodiment one
Embodiments provide a kind of method determining clock equipment.The executive agent of the method can be from clockwork.
It is a kind of network equipment from clockwork, can be bearer network equipment from clockwork, it is also possible to be base station equipment.Fig. 1 is this
The flow chart of a kind of method determining clock equipment that inventive embodiments provides.The method includes:
101, receiving the first message that the first clockwork sends, comprise the first clock grade information in this first message, this is first years old
Clock grade information is determined by very first time class information, first frequency class information and preset function, this very first time grade
Information is for identifying the time precision of this first clockwork, and this first frequency class information is for identifying this first clockwork
Frequency accuracy.
Class information is for identifying the precision of clockwork.Time class information is for identifying the time precision of clockwork.Frequency
Class information is for identifying the frequency accuracy of clockwork.Class information can be numerical value, it is also possible to be expression formula.Need explanation
, class information be numerical value scene under, the height of precision does not has necessary connection with the size of the value of class information.Such as,
In the case of the precision of the first equipment is higher than the second equipment, the value of the class information of the first equipment and the class information of the second equipment
Value can be 1 and 2 respectively；The value of the value of the class information of the first equipment and the class information of the second equipment can also be 2 respectively
With 1.It addition, class information be expression formula scene under, the height of precision does not has necessary connection with choosing of expression formula.Example
As, in the precision of the first equipment higher than in the case of the second equipment, the expression formula of the class information of the first equipment and the second equipment
The expression formula of class information can be A and a respectively；The expression formula of the class information of the first equipment and the class information of the second equipment
Expression formula can also be a and A respectively.
First clockwork is clock equipment.Very first time class information and first frequency class information are respectively used to mark should
The time precision of the first clockwork and frequency accuracy.
When implementing, very first time class information can be decimal scale 6.Decimal scale 6 identifies the time essence of the first clockwork
Degree can be error ± 10-11 second.Very first time class information can also decimal scale 7.Decimal scale 7 identifies the first clockwork
Time precision can be error ± 5 × 10-10 second.About time precision grade, specifically it is referred to the 1588 agreement second editions.
When implementing, first frequency class information can be decimal scale 2, it is also possible to be decimal scale 4.About decimal scale 2 and ten
The frequency accuracy of system 4 correspondence, specifically refer to International Telecommunication Union's telecommunication standardsization tissue (ITU-T for ITU
Telecommunication Standardization Sector) the G.781 agreement issued.
In the present embodiment, this first clock grade information is by very first time class information, first frequency class information and default letter
Number determines, refers to very first time class information and the first frequency class information of the first clockwork are substituted into this preset function,
To functional value be the first clock grade information.

The order of level.When the priority of the first clockwork is higher than the priority of second clock equipment, determine that the first clockwork is main
Clockwork.
Above-mentioned priority selects the priority of clock equipment suitable for instruction from clockwork from multiple alternative clock equipment
Sequence.Can be in the way of defining the height determining priority from clockwork.Below to determining that mode is illustrated:
When clock class information is magnitude value, height and the priority of the value of clock grade information can be defined from clockwork
Height is directly proportional, and the height of value that can also define clock grade information from clockwork is inversely proportional to the height of priority.
When clock class information is the expression formula being made up of single English alphabet, the height of priority can be defined from clockwork
Relevant with the sequence priority of English alphabet.Such as sorting the most forward, priority is the highest；Or it is the most forward to sort, and priority is the lowest.
The height of priority and the case sensitive of English alphabet can also be defined, corresponding excellent of such as capitalization English letter from clockwork
The priority that first level is corresponding higher than small English alphabet；Or the priority that small English alphabet is corresponding is higher than capitalization English letter pair
The priority answered.
According to mentioned above, clock grade information is the value of above-mentioned preset function.The value of preset function can be numerical value, it is possible to
To be expression formula.It should be noted that under the value of preset function is the scene of numerical value, the height of priority and the size of numerical value
There is no the contact of certainty.When the value of preset function under the scene of expression formula, the height of priority does not has with choosing of expression formula yet
Necessary connection.It is exemplified below:
As a example by the value of preset function corresponding to the clock grade information scene as numerical value: in the priority of the first equipment higher than second
In the case of equipment, the clock grade information of the first equipment and the clock grade information of the second equipment can be 1 and 2 respectively；The
The clock grade information of one equipment and the clock grade information of the second equipment can also be 2 and 1 respectively.
As a example by the value of preset function corresponding to the clock grade information scene as expression formula: in the priority of the first equipment higher than the
In the case of two equipment, the clock grade information of the first equipment and the clock grade information of the second equipment can be A and a respectively；
The clock grade information of the first equipment and the clock grade information of the second equipment can also be a and A respectively.
