Embodiment 1
Embodiments provide a kind of sequence number generation method.Fig. 1 is the process flow diagram of the sequence number generation method according to the embodiment of the present invention.As shown in Figure 1, it is as follows that the method comprising the steps of:
Step S11, obtains trigger pip, and trigger pip generates new sequence number for triggering.
Concrete, when needing to generate new sequence number, send trigger pip to server.Whether get trigger pip by step S11, judge whether to generate new sequence number.
Step S13, according to trigger pip, obtains the number parameter n of counter.
Concrete, in step s 13, when getting trigger pip, obtain the number parameter n in counter, wherein, number parameter n as a part for sequence number, for marking the quantity of formation sequence number.Certainly, the number parameter n in counter can reset once, to be recorded in the number of the sequence number generated in current time interval each regular time.Such as, can per hour, every day, weekly the number parameter n in counter is reset.
Step S15, according to trigger pip, obtains present system time.
Concrete, in step S15, when getting trigger pip, except obtaining the number parameter n in counter, also obtain the time of current system.Wherein, system time can be the system time receiving trigger pip, also can be the system time performing sequence number generation method, also can be the transmitting apparatus sending trigger pip, the system time obtained from transmitting apparatus when sending.In addition, in advance according to the frequency that sequence number generates, the precision obtaining system time can also be set.
Step S17, at least according to number parameter n and system time according to serial number gencration algorithm formation sequence number.
Concrete, in step S17, the system time that the number parameter n got by step 13 to major general and step 15 are got combines according to predetermined serial number gencration algorithm, formation sequence number.Concrete generating algorithm, can according to the demand of reality, to number parameter n and system time according to predetermined rule, carries out arranging, combining, generates the sequence number conformed to actual demand.
In addition, can also according to trigger pip, obtain the facility information such as IP address, MAC Address, IMEI sequence number of the transmitting apparatus sending trigger pip, facility information for the server of formation sequence number, when formation sequence, can one or more according to serial number gencration algorithm formation sequence number by the above-mentioned facility information got.
By above-mentioned steps S11 to step S17, obtain trigger pip, and obtain the number parameter n and system time that are used for formation sequence number according to trigger pip, by number parameter n and system time according to serial number gencration algorithm, formation sequence number.Said method, at least carry out formation sequence number by number parameter n and this Two Variables of system time, both the quantity of formation sequence in section sometime number had been reflected in by number parameter n, again by the temporal information of system time reflection sequence number generation, also utilize above-mentioned number parameter n and system time at least Two Variables simultaneously, avoid sequence number to repeat the problem generated.
In summary, the invention solves in prior art and use from increasing sequence number, the sequence number caused repeats, and the problem of poor stability, achieves at least by number parameter n and system time Two Variables formation sequence number, prevent the effect that sequence number duplicates.
Preferably, in the above embodiments of the present application, in step S17 at least according to number parameter and system time according in serial number gencration algorithm formation sequence number, comprising:

First acquisition module, for obtaining trigger pip, described trigger pip generates new sequence number for triggering;
Second acquisition module, for according to described trigger pip, obtains the number parameter n of counter;
3rd acquisition module, for according to described trigger pip, obtains present system time;
Processing module, at least according to described number parameter n and described system time according to serial number gencration algorithm formation sequence number.
10. device according to claim 9, is characterized in that, described processing module comprises:
First generates submodule, for generating the init string of predetermined figure;
Second generates submodule, for described number parameter is replaced described init string, generates intermediate character string;
3rd generates submodule, for described system time being replaced described intermediate character string, formation sequence number.
11. devices according to claim 10, is characterized in that, described device also comprises:
Judge module, for comparing described number parameter n and the threshold value pre-set;
First arranges module, and the described number parameter n of described counter, when described number parameter n is more than or equal to described threshold value, is set to 0 by application;
