Embodiment
Receive in the process of note at terminal equipment, network side note treatment facility has not only sent content, the sending side terminal equipment number of note to terminal equipment, but also the temporal information when having sent forwarding short message.This time is actual to be exactly the time of operator's equipment because operator's equipment time relationship to charge accurately and communication normal, so the operator generally has professional Time Synchronization Network to guarantee that the time of its equipment is accurate.So just guaranteed the accuracy of time reference.
Technical conceive of the present invention is to utilize the function of receiving and sending short message of existing terminal equipment, temporal information by the transmitting-receiving note, and the forwarding time information of the network side note treatment facility that carries in the existing note is realized automatic correcting time, do not need network side to change any handling process, according to this technical conceive, the invention provides two kinds of automatic correcting time methods, be respectively instant calibration method and calibration method at random, below with specific embodiment and be described with reference to the accompanying drawings.
Embodiment one, instant calibration method
Terminal equipment sends the note that target terminal equipment number is consistent with this terminal equipment number, and the temporal information of the current terminal equipment of record delivery time, network side note treatment facility is after receiving note, to this note be transmitted back this terminal equipment according to the purpose terminal equipment number of note, in note, increase the temporal information of current network side note treatment facility simultaneously.After terminal equipment received the note that network side returns, recorder is the temporal information of current terminal equipment constantly, and obtained network side and transmit time information from this note, handled when carrying out the school immediately according to the relevance between the above-mentioned temporal information then.Like this, terminal equipment only need be realized the automatic correcting time function by a note, note when the present invention's note that this target terminal equipment number is consistent with this terminal equipment number is called the school, and concrete steps comprise as shown in Figure 1:
Note when S101, end side send the school that local terminal receives to network side, and the delivery time T1 of note when writing down this school;
Function choosing-item or button when at first on terminal equipment, the school being set, the user carries out function choosing-item or presses when this button triggers the school and order, when terminal equipment receives user's school after the order, trigger note when sending the school, the target terminal device number of note is this terminal equipment number during this school, and the content of note can be empty (suggestion so reduces amount of information), also can be the predefined content of manufacturer, and the delivery time information of note be T1 when writing down this school;
S102, when network side note treatment facility is received the school after the note, according to existing note handling process, note when transmitting this school, and when transmitting, increase automatically and transmit T3 constantly according to the target terminal equipment number in the note.Because the purpose terminal equipment number of note is consistent with transmission terminal equipment number during the school, note will be returned the terminal equipment of note when sending the school along original path during this school;
S103, terminal equipment side when receiving note, the terminal equipment time T 2 of note during this school of recorder, and the forwarding of the network side note treatment facility that carries in the note when extracting school T3 constantly;
S104, terminal equipment basis of calculation time T also proofread and correct local zone time and are this standard time T, T=T3+ (T2-T1) ÷ 2+ Δ T4, and this standard time T is the time data that writes the terminal equipment realtime clock chip;
Wherein: the transmit after receive time delay of note is T2-T1 during the school, it is consistent to the information path that the information path of network side note treatment facility and terminal equipment receive the note that network side note treatment facility transmits back to consider that terminal equipment sends note, the time of experience also thinks identical, test by reality, generally from delivery time T1 to the time of reception T2 the interval very little, so note comes and goes the inconsistent very little especially of elapsed-time standards, this difference can be accepted when the terminal equipment school, so network side note treatment facility can be thought Δ T3=(T2-T1) ÷ 2 to the short message receiving-transmitting delay parameter between the terminal equipment, the standard time when then terminal equipment receives the school during note is T3+ Δ T3=T3+ (T2-T1) ÷ 2;
Δ T4 is that terminal equipment receives the time interval that note arrives the moment when specifically carrying out the school, then terminal equipment is specifically carried out standard time T=T3+ (T2-T1) the ÷ 2+ Δ T4 of timing, time interval Δ T4 〉=0, determine that according to the terminal equipment disposal ability be generally a constant, the terminal equipment disposal ability is strong more, Δ T4 should be more little, even can ignore, according to different terminal equipments, the technical staff can accurately measure the value of Δ T4.
After terminal equipment calculates standard time T, regulate the terminal equipment time deviation automatically, realize automatic correcting time by software.
Said method only need increase the relevant treatment flow process in end side, note during by the transmission school, and during according to the school moment of delivery time, the time of reception and the network side forwarding short message of note calculate standard time information, again according to standard time information correction local zone time, correction mechanism realizes in end side fully, do not need the software and hardware of the communication apparatus of existing network side operator is carried out any change, therefore can be applied in the communication network of existing various standards, and the correction reference source of this method is the precise time of network side, has guaranteed the correction accuracy; When the expense of 1 note of user effort had just realized accurate school, real-time was good, when being applicable to new clothes Battery Terminal Equipment school and be badly in need of certain situation such as correct time.
Embodiment two, calibration method at random
Terminal equipment in use, owing to frequency departure, the terminal equipment of crystal inside falls, battery does not have reasons such as electricity for a long time, may cause the clock time of terminal equipment and produce deviation between the standard time, for compensating the deviation that above-mentioned reason produces, the present invention also provides a kind of time of reception of utilizing normal short message and transmits method when constantly carrying out school at random, this method can be used separately, also can cooperate embodiment one application.
Calibration method can be carried out when receiving each bar note at random, be that terminal equipment is when receiving a note, obtain the time of reception and the forwarding of this note and also calculate when receiving this note constantly, the deviate of local zone time relative standard time is: forwarding constantly adds that the one way transmission time of note between network side note treatment facility and terminal equipment deducts the time of reception again; Then with deviate of local zone time compensation.
Calibration method also can utilize many continuous notes to realize at random, principle is during the school: be t2 the time of reception of supposing a normal short message, transmitting constantly is t3, network side note treatment facility is Δ t3 to the one way transmit after receive time delay parameter of the note between the terminal equipment, then when this note is received, the difference DELTA t=t3+ Δ t3-t2 of terminal equipment and network side standard time, Δ t is generally produced by the accumulation of crystal oscillator frequency deviation, therefore after local zone time being compensated this difference, local zone time can be corrected to the network side standard time and be consistent, wherein: if the described bearing calibration at random of present embodiment is used separately, then Δ t3 can rule of thumb be worth setting, if the described bearing calibration at random of present embodiment cooperates embodiment one to use, then the accurate measured value that can calculate Δ t3 according to the temporal information of proofreading and correct note among the embodiment one is: Δ t3=Δ T3=(T2-T1) ÷ 2, the empirical value of Δ t3 and accurately measured value be kept at respectively in the special-purpose memory block.
According to Principle of Statistics, consider that mistake may appear in the temporal information that the wall scroll note is carried or write down, and, the position of terminal equipment might change, for avoiding consequent unreasonable compensation, reach comparatively accurate deviation compensation, generally do not proofread and correct at any time according to the temporal information of wall scroll note, but after receiving N bar note, the temporal information of this N bar note of comprehensive statistics is proofreaied and correct, generally can set N more than or equal to 10 and smaller or equal to 20, the comprehensive statistics method can select following any one:
1, the mean value of N the Δ t that will calculate respectively according to N bar note is as the difference DELTA t ' that proofreaies and correct;
2, remove after N the maximum and minimum value among the Δ t, the mean value of N-2 Δ t of residue is as the difference DELTA t ' that proofreaies and correct;
3, with all N Δ t rank order, remove preceding two and latter two then after, the mean value of N-4 Δ t of residue is as the difference DELTA t ' of correction.
Like this, after terminal equipment is received note at every turn, calculate difference DELTA t and the preservation of the time of reception and the standard time of this note, when the difference DELTA t of the note that accumulative total is preserved reaches N of setting, calculate Δ t ' according to one of above-mentioned three kinds of methods, and with Δ t ' of local zone time compensation, being about to local zone time increases Δ t '.When this method of execution, terminal device prioritizes selects the accurate measured value of Δ t3 to calculate, and promptly at first judges whether to preserve the accurate measured value of Δ t3, if then utilize accurate measured value to calculate Δ t and Δ t ', otherwise, utilize the empirical value that is provided with to calculate.
For preventing that the terminal cumulative departure is too big, cause trueness error, can set effective reception duration threshold value M of the N bar note that is used for compensation correction, for example M is 5 days, if article one the reception span of note and N bar note was greater than 5 days, when then not carrying out the school at that time, the temporal information of deletion article one note waits and receives when judging whether to carry out the school according to duration threshold value M again after next bar note.
Here need to prove, generally, note from the time that the network equipment is forwarded on the terminal equipment to be spent be uncertain, with send terminal equipment, the residing wireless communication networks of receiving terminal apparatus geographical position relation is very big.This time value generally less (being generally less than 1 second) but, the deviation effects that produces during to the school is little, can also be provided with a constant come approximate substitution it, this deviation will further reduce like this, the result is an ordinary terminal equipment user acceptable during final school.
Be that example is elaborated when utilizing continuously the school at random of many notes below, after at first setting the empirical value of reception duration threshold value M, Δ t3 of the total number N of note when being used to carry out school at random, N bar note, the concrete steps of calibration method comprise as shown in Figure 2 at random:
S201, each time carry out during the school at random after, terminal equipment is with note total number count value I zero clearing and be Δ t3 assignment;
If this method and embodiment one described instant bearing calibration are used, after then instant correction is performed, store the exact value of Δ t3 in the terminal equipment, after carrying out during the school at random each time, terminal equipment should at first read the exact value of Δ t3 and carry out assignment, if the memory block of exact value is empty, the empirical value that then reads Δ t3 again carries out assignment.
Whether S202, monitoring receive a note, if then continue step S203, otherwise this step S202 that circulates;
S203, obtain the t2 and the transmit t3 constantly time of reception of this note, when calculating this note and being received, the difference DELTA t=t3+ Δ t3-t2 of terminal equipment and network side standard time is then with count value I increase by 1;
S204, judge whether I equals N,, otherwise return step S202 if then continue step S205;
In S205, the N bar note, whether the time interval between the time of reception of the time of reception of a note and the last item note is smaller or equal to M the earliest, if then continue step S206, otherwise the deletion time temporal information of a note the earliest, return step S202 after I reduced 1;
S206, calculating Δ t ';
S207, with Δ t ' of local zone time compensation, promptly the time of the local zone time after the compensation before for compensation adds a Δ t '.Return step S201.
According to said method, can be within the specific limits with the Deviation Control of local zone time, for example deviation is 1,000,000 negative/time, per 1,000,000 seconds, promptly about 12 days, the local zone time of terminal equipment can be walked slow 1 second, if M is set to 5 days, then can be in 1 second with the local zone time Deviation Control.
When this method is used separately, on the basis when the manual school of user, the note that basis is at random received compensates, even the accuracy during the manual school of user is relatively poor, after compensation several times, can constantly dwindle the timing error that deviation and automatic compensated crystal crystal oscillator frequency deviation cause.If this method cooperates embodiment one accurate calibration method use, the timing error that causes of compensated crystal crystal oscillator frequency deviation need not any expense of user effort or carries out any operation automatically, just can keep the accuracy of local zone time substantially.
The essence of above-mentioned two kinds of calibration methods of the present invention all is when standard time of utilizing the network equipment that carries in the note realizing the school for benchmark, and realizes automatically in end side fully, does not need to revise any handling process of network equipment.
