Specific embodiment
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings and specifically real
The present invention is further detailed explanation to apply mode.
During due to communication terminal to the synchronization of time server request time, when time server may return time-out or lose
Between information, thus cause current sync failure.In order to improve time synchronized success rate, prior art is using default multiple time clothes
Business device address, when current time server returns unsuccessfully, then sends out to next time server after separated in time again
Rise synchronous.But it cannot be guaranteed that the success rate of first time time synchronized reduce the speed of time synchronized.
For the problems referred to above, the invention provides a kind of success rate that can improve first time time synchronized can be quickly complete
Become method for synchronizing time and the communication terminal of time synchronized.
Below, it is described in detail by each embodiment following.
Embodiment one:
With reference to Fig. 1, show a kind of method flow diagram of time synchronized of the embodiment of the present invention one, the method is specifically permissible
Comprise the following steps:
Step 101, time server number n of the address of default m time server and continuous synchronization, described m, n are equal
For natural number, and m >=n >=2.
In the embodiment of the present invention, time server using gps signal as time source, certainly also may be selected Big Dipper signal,
The time sources such as irig-b code, ocxo, rubidium atomic clock, cdma signal, time server embeds ntp (network time
Protocol, NTP)/sntp (simple network time protocol, SNTP) association
View, the communication terminal such as computer in synchronizing network, mobile phone, net book.The operation principle of ntp/sntp agreement is by exchanging
Time server and the timestamp of communication terminal, calculate communication terminal with respect to the time delay of time server and deviation, thus
Realize the synchronization of time.
First, communication terminal obtains the address of institute's time server in a network, such as 129.7.1.66ntp-
Sop.inria.frserver 210.72.145.44 (China national time service central server ip address),
Ntp.sjtu.edu.cn (network center of Shanghai Communications University ntp server address) etc..For ensureing synchronous success rate, to the greatest extent may be used
Can how obtain server address, in the present embodiment, from all servers getting selection m(the present embodiment m=5) individual when
Between server default in communication terminal naturally it is also possible to all server address getting all are defaulted to communication terminal
Interior, the invention is not limited in this regard.And set time server number n(the present embodiment n=2 of continuous synchronization).
Step 102, continuously initiates time synchronized request, described n time clothes to n time server by described address
Business device is chosen from high to low according to pre-set priority from described m time server.
First described m time server is ranked up according to pre-set priority in the present embodiment, pre-set priority sorts
Can be to consider heterogeneous networks, server be ranked up after the factor of different time zone, for example, using close to communication terminal
Server higher with respect to the successful probability of server sync farther out from communication terminal, using the server phase in LAN
Higher for the successful probability of the server sync in wide area network, therefore can will be in LAN and nearest from communication terminal
The priority of time server is set to highest.
In the present embodiment, choose 2 from 5 time servers, selection mode is carried out from high to low according to priority, example
As, this 5 time servers of server1- server5 according to pre-set priority order from high to low be server1,
Server3, server5, server2, server4, because the time server number of continuous synchronization setting is as 2, therefore
Using server1, server3 as this 2 continuous synchronization time server.
It has been preset with the address of server1, server3, according to this address to this 2 time servers in communication terminal
Continuous time synchronized of initiating is asked, and the order initiating request can be carried out according to priority, for example, first initiate the time to server1
Synchronization request, then initiates time synchronized request to server2.Continuously initiate time synchronized to n time server to refer to,
Initiate communication terminal without waiting for server1 returning result after synchronization request to server1, and be to continue with to server2
Initiate request.
Step 103, receives the returning result of described n time server, judges whether described returning result comprises at least
One temporal information, is then if so, one of temporal information by system time synchronization；Otherwise, terminate this time synchronized.
Time server receives after the request of communication terminal, and timestamp is returned to communication terminal, wherein timestamp
Including the temporal information obtaining from time source.
Because time server is busy or failure and other reasons, (communication terminal sets fixed to cause time server to return time-out
When device, when reaching setting time, also non-returning result then judges time-out) or return error message (such as dns parses mistake, or mesh
Mark address is unreachable), now communication terminal does not just receive temporal information, just cannot deadline synchronization yet.In the present embodiment,
Continuously initiate synchronization request to multiple time servers, if at least one time server time of return information, this is described
Time synchronized is successful.If all non-time of return information of all time servers, the failure of this time synchronized.
In the embodiment of the present invention, communication terminal can be continuous at least two time servers in first time time synchronized
Time synchronized request is initiated on ground, it is to avoid need after current sync failure to wait certain time just can carry out that next is subsynchronous,
Ensure that communication terminal carries out the success rate of time synchronized in first time.And continuously initiated time synchronized request time take
Business device is to choose from high to low according to default priority, is further ensured that and just can become when first time initiating synchronization request
The work(deadline is synchronous.
Embodiment two:
With reference to Fig. 2, show a kind of method flow diagram of time synchronized of the embodiment of the present invention two, the method is specifically permissible
Comprise the following steps:
Step 201, communication terminal opens network communicating function and time synchronized function.
Step 202, time server issues address by network.
Step 203, communication terminal receives described address and is stored in memory, chooses m=10 Time Service therein
Device, and set the time server number of continuous synchronization and as n=4 and retry synchronization times as k=3 time.
Preferably, 10 time servers chosen are marked, and the mapping relations of recording mark and address.Example
As being labeled as s1-s10.
Retry synchronization and refer to after this synchronization failure, then re-start time synchronized.In the present embodiment, same when for the first time
After walking unsuccessfully, then retry 2 times.
Step 204, from m time server, according to pre-set priority, order from high to low chooses n Time Service
Device.
Pre-set priority can rule of thumb voluntarily be arranged, and in the present embodiment, considers above-mentioned 10 time server institutes
In network and time zone factor, it is ranked up, such as by from communication terminal, recently and the time in same LAN takes
Business device is classified as highest priority, and concrete grammar is referring to step 101.Assume that the order after 10 time server sequences is: s6,
s2、s3、s1、s7、s5、s8、s10、s9、s4.
The time of 4 continuous synchronization in the present embodiment, is chosen from above-mentioned 10 time servers according to priority orders
Server, respectively s6, s2, s3, s1.
Step 205, judges whether the value of k is more than 0, if then execution step 206, otherwise the end time is synchronous.
Step 206, communication terminal continuously initiates time synchronized request to n time server by described address.
After the time server determining continuous synchronization is s6, s2, s3, s1, according to mark and the mapping relations of address, to
This 4 time servers send time synchronized request.
Specifically, described step 206 also includes following sub-step:
Sub-step a1, chooses i-th time server according to pre-set priority order from high to low, to this Time Service
Device sends time synchronized request, wherein i=1.
Sub-step a2, the value of i is added 1, and judges i≤n, if then returning sub-step a1, otherwise terminates to send request, and
Execution step 207.
Step 207, communication terminal stand-by period server returning result.
Step 208, judges whether the equal returning result of n time server, if then execution step 209；Otherwise return step
Rapid 207.
Step 209, judges whether include at least one temporal information in returning result, if then execution step 210；Otherwise
Execution step 211.
In the present embodiment, returning result can include temporal information corresponding with time source, error message or time-out information,
If wherein return is error message or time-out information, illustrate that this time server returns unsuccessfully.
Step 210, system time synchronization is one of temporal information.
If there is multiple time servers equal time of return information, when choosing one of temporal information and being set to system
Between, the deadline is synchronous.
Step 211, the value that the value of k is deducted 1, n adds 1, and return to step 205.
After the failure of this time synchronized, again initiate time synchronized request to the individual time server of n ', described n ' is certainly
So count, and n ' > n, in the present embodiment, n '=n+1, that is, under subsynchronous when continuous synchronization time server number more continuous than this
Synchronous time server number is many, so can improve next hyposynchronous success rate.
Embodiment three:
With reference to Fig. 3, show a kind of Part Methods flow chart of time synchronized of the embodiment of the present invention three, the present embodiment walks
Rapid 301-307 is similar to embodiment two step 201-207, will not be described here.From unlike embodiment two, in communication terminal
After stand-by period server returning result, execution step 308.
Step 308, judges whether returning result is temporal information, if then execution step 309, otherwise execution step 310.
Step 309, improves the priority of corresponding time server, and execution step 311.
Even if being set as the success rate of the time server time of return information of optimum it can also happen that change, for example, service
Device failure and other reasons, are so likely to result in communication terminal according to set prioritization and initiate time synchronized failure for the first time
Probability increases.What time server returned is temporal information, and this time server energy normal work is described, its priority is improved
Afterwards, when communication terminal needs time synchronized again, the ranking of this time server will be located further forward, and therefore initiates same for the first time
Walk successful probability also bigger.
Step 310, reduces the priority of corresponding time server, and execution step 313.
As described previously for the time server of cisco unity malfunction, for example, return time-out information or return error message,
Reduce its priority and be also equivalent to reduce the risk of synchronization failure, equally can reach the success improving first time time synchronized
The effect of rate.
Step 311, judges whether the temporal information returning is first temporal information reaching, if then execution step
312, otherwise ignore this temporal information.
Step 312, records this temporal information, and execution step 313.
In time of return information, might not return according to the order sending request, for example, be labeled as the time clothes of s2
The temporal information that business device returns reaches communication terminal at first, and s1 takes second place.The temporal information of record s2, ignores the temporal information of s1.
And in following step 316 synchronous s2 temporal information, so can guarantee that the priority to n time server all realizes adjustment
In the case of, it is to avoid when there is multiple server time of return information, repeat to arrange system time.
Step 313, judges whether the equal returning result of n time server, if then execution step 314, otherwise returns step
Rapid 307.
So just can guarantee that the priority to n time server is all realized adjusting.
Step 314, judges whether that n time server all returns failure, in this way then execution step 315, otherwise executes step
Rapid 316.
Step 315, the value of k is deducted 1, and return to step 305.
Step 316, the temporal information that system time synchronization is record, the deadline is synchronous.
In the present embodiment, priority can be adjusted according to the result that time server returns, by successful time of return information
Server precedence improves, and the server precedence returning failure reduces, so when the next time period carries out time synchronized, from
It is easier successful time of return information according to the n time server that priority is chosen from high to low in m time server, carry
High first hyposynchronous success rate.
For aforesaid each method embodiment, in order to be briefly described, therefore it is all expressed as a series of combination of actions, but
It is that those skilled in the art should know, the present invention is not limited by described sequence of movement, because according to the present invention, certain
A little steps can be carried out using other orders or simultaneously.Secondly, those skilled in the art also should know, is retouched in specification
