At this, exemplary embodiment of the present invention and explanation thereof are used for explaining the present invention, but alsoNot as a limitation of the invention.
For existing problem in aforementioned prior art, the present invention, by calculating sending the time of mobile phone matched signal, realizesExact matching, thereby realized aspectant two people by mobile phone collide, matching request is while sending simultaneously, can be rapidMatch. As shown in Figure 1, comprising:
Step 101, obtains network-induced delay the record of each terminal of mating in advance;

In step 104, from described system time Server_time_1, in window time tw, obtain second eventuallyThe matching request information of end, wherein, the maximum in the time delay that this window time tw is system log (SYSLOG)Value: tw=MAX[Offset_time];
If do not get the matching request information of the second terminal in described window time tw, notify first terminal coupling to loseLose, again obtain the solicited message of first terminal.
If get the solicited message of N terminal in described window time tw simultaneously, record gets this N respectivelyThe system time of terminal; According to the network-induced delay of the system time of this N terminal and this N terminal of getting in advanceCalculate respectively the request time Ask_time_x of this N terminal; Relatively request time and the first terminal of this N terminal one by oneThe absolute value of request time difference | whether Ask_time_x-Ask_time_1| is greater than predetermined threshold value; If not, judging shouldTerminal meets time match condition; Mate described first terminal and the terminal that meets time match condition; If this N terminalThe difference of request time and the first request time is all greater than predetermined threshold value, and it fails to match to notify first terminal, and again obtainThe solicited message of first terminal.
Wherein, before mating first terminal and meeting the terminal of time match condition, also comprise: obtain and meet time match barThe GPS information of the terminal of part and the GPS information of first terminal; According to the GPS letter of the described terminal that meets time match conditionBreath and the GPS information of first terminal, by with described first terminal not at terminal end of the time match condition that meets of the same areaOnly coupling.
The network-induced delay that obtains in advance each terminal of mating described in step 101 is specially, and described each terminal is to clothesBusiness device carries out poll, records initial time t_start and the termination time t_end of the each poll of described each terminal, and shouldInitial time and termination time send to server in the time of upper once poll;
The computational methods of network-induced delay Offset_time are:
Offset_time={ ∑ [(t_end-t_start)/2] }/n, wherein n is initial time and the termination that server is recordedThe number of time.
In above-mentioned steps, the method for computation requests time is: Ask_time=Server_time-Offset_time. Wherein,Ask_time is request time; Server_time is system time; Offset_time is time delay.
For example:
User terminal A starts poll from local zone time 12:00:00:00, and server receives the system time of polling messageFor 12:00:00:58, be 12:00:01:00 and user terminal A receives the time of server return information, like this, thisJust be (12:00:01:00-12:00:00:00)/2=00:00:00:30 the time delay of inferior poll, calculates n pollTime delay, then average.
Describe below by specific embodiment:
Embodiment mono-
As shown in Figure 2, be the flow chart of the method for a kind of real-time matching communication terminal of the present embodiment.
Hand over the application scenarios of the present embodiment at this:
The first and second two users hold respectively mobile terminal A and B, wish to mate rapidly the other side by this programme. Realize this programmeWhole process time very short, thereby two users can not move on a large scale in this process, that is, residing networkEnvironment is constant.
Concrete, A can collide with B together with mobile terminal separately, and like this, two terminals just can be sent coupling simultaneouslySolicited message.
Step 201 obtains network-induced delay the record of A and B in advance.
First, the first and second two people will open " real-time matching " application in mobile terminal A and B. After opening, two endsEnd start with server ask to carry out poll by Http, this poll until " real-time matching " generation just finish. Same therewithTime, the gravity sensor of client device starts the crash-active of monitor user '.
For saving the communication resource, in clients poll process, only send heartbeat data packets to server, when terminal gets clothesWhen servertime that business device returns, can calculate this poll according to the time and the servertime that send heartbeat data packetsNetwork-induced delay.
After end of polling(EOP), system can, according to the network-induced delay calculating mean value obtaining at every turn, be carried out record by this mean value,The network-induced delay Off_time obtaining in advance as system, carries out subsequent calculations.
As shown in Figure 3, be the schematic diagram of client and server interaction, as shown in the figure, vertical direction is time shaft, eachIndividual triangle represents the once request of client and server and replys. Schematic diagram from InitailingState state,Until mating, both sides confirm successfully. Each request and response are polls, in each poll, do not transmit large data,Very little heartbeat data, each polling server to the system time of major general's server (servertime, unit is second,Value, for the floating number of double type, is accurate at most 2 significant digits) take back, if server has new data to needPass a client, along being taken back.
Bump_time is the collision moment, this is a key parameter of server coupling, and server need to be known two sending outBump_time, as figure shows:
Bump_time=t_server–Offset_time
But server does not also know Offset_time is how many, therefore server needs to pass and to come according to poll aboveMaxoffset and minoffset remove to estimate Offset_time.
The estimation of this parameter, very large to the influential effect of coupling, accurately as much as possible must be estimated to real value, necessaryRemain on certain precision inherent this, following three schemes are provided:
Scheme one: use the value of the maxoffset of server the last time to be Offset_time.
Scheme two: use the mean value of maxoffset,
Offset_time=1/n*(maxoffset1+maxoffset2+…+maxoffsetN)。
Scheme three: the evaluation method on probability of use, as maximal possibility estimation.
Wherein, the accuracy of scheme one is minimum, and the maximal possibility estimation in scheme three needs server that a large amount of poll numbers is providedAccording to. Thereby the present embodiment is preferred, take the estimation algorithm method of scheme two as this programme.
For example:
Mobile terminal A starts poll from local zone time 12:00:00:00, and server receives the system time of polling messageFor 12:00:00:58, be 12:00:01:00 and user terminal A receives the time of server return information, like this, thisJust be (12:00:01:00-12:00:00:00)/2=00:00:00:30 the time delay of inferior poll, calculates n pollTime delay, then average. Be 28 milliseconds the time delay of the mobile terminal A calculating, in like manner calculatesTime delay of mobile terminal B be 30 milliseconds.
Step 202, obtains the matching request information of A, and records the system time that gets this solicited messageServer_time_A。
Wherein, due to network-induced delay difference, the time of user A and B matching request arrival server can be definitely not identical,The terminal that solicited message is first arrived to server is as first terminal.
In the present embodiment, suppose first to receive the matching request information of A.
After gravity sensor detects the crash-active of equipment, triggering terminal sends matching request letter to server immediatelyBreath, because this request is by the action triggers of collision, thereby theoretically, two terminals are sent the time of requestIt is the same time. These are different from the trigger action of " shaking " in micro-letter, and it is " same that " shaking " cannot realize coupling both sidesOne time " send match information, thereby also cannot realize aspectant coupling.
Step 203, according to Server_time_A and the network-induced delay Offset_time_A of the A obtaining in advance calculateThe request time Ask_time_A of A.
The method of computation requests time is: Ask_time=Server_time-Offset_time.
According to the method, Ask_time_A=Server_time_A-Offset_time_A.
Because two residing network environments of terminal are identical, from poll, until collision end, all in identical network ringsBorder, thereby the request time calculating by said method approaches actual collision time of origin very much.
While supposing that the first and second two people collide mobile terminal A and B, the local zone time of mobile terminal A is 12:00:10:00,The system time that server receives the matching request of A is 12:00:10:58, and the request time calculating is:
Ask_time_A=12:00:10:58-00:00:00:28=12:00:10:30。
Step 204, the solicited message that receives A starts, and obtains matching request information the record of B in window time twSystem time Server_time_B.
Wherein, the A that this window time tw is system log (SYSLOG) and larger value in the time delay of B:tw=MAX[Offset_time]。
Suppose that A and B collide at one time, server is first received the collision information of A, but because network speed is inconsistent,In more late a period of time of collision information of possible B, just can come, A waits for coming of B at least will to chance of B so,The long window time tw that is of time of this wait.
The size of tw at least should be greater than the network delay maxoffset_b of B, but server do not know whose be usedMaxoffset, so in order to ensure have a chance to carry out and other people coupling to all people, server can use works asFront known maximum maxoffset, that is: tw=MAX[Offset_time].
Here, the value of tw is specially 30 milliseconds.
Step 205, the request time of calculating B.
Ask_time_B=Server_time_B-Offset_time_B；
Suppose that server receives that the system time of the solicited message of B is 12:00:10:59, calculates the request time of BFor: Ask_time_B=12:00:10:59-00:00:00:30=12:00:10:29.
Step 206, the relatively absolute value of A and B request time difference | it is default whether Ask_time_B-Ask_time_A| is greater thanThreshold value, if not, mates A and B, and it fails to match if so, to notify A and B.
In the present embodiment, | the value of Ask_time_B-Ask_time_A| is 1 millisecond.
Predetermined threshold value is according to the predefined value of the result of test of many times, is generally not more than tw, no longer than 50 milliseconds,0.5 second. The present embodiment is preferred, is less than minimum network delay value, specific to the present embodiment, is less than exactly 28 milliseconds.
For example, predetermined threshold value is 20 milliseconds, and clearly, 1 millisecond is less than 20 milliseconds, coupling A and B.
Embodiment bis-
As shown in Figure 4, be the flow chart of the method for a kind of real-time matching communication terminal of the present embodiment.
Suppose, in the time that A and B collide, to also have C, D, E, tetra-users of F, also will collide, samePeriod has been opened matching feature, and wherein, A and B, C and D are in Haidian District, Beijing City, and E and F are in Xi'an City, Shanxi Province.
Step 401, obtains network-induced delay the record of A, B, C, D, E, F in advance;
Within the same period, system can get the poll of A, B, C, D, E, six users' of F terminal, and collision occursTime, calculate respectively network-induced delay corresponding to each terminal.
Step 402, obtains the matching request information of first terminal, and records the matching request information that gets this first terminalSystem time Server_time_1;
Here, the terminal of supposing party A-subscriber is first terminal, that is, system is subject to the matching request letter that party A-subscriber sends at firstBreath.
Step 403, according to the network-induced delay of this system time Server_time_1 and this first terminal of obtaining in advanceOffset_time_1 calculates the first request time Ask_time_1;
Step 404 from this system time Server_time_1, is obtained N-1 terminal of residue in window time twMatching request information record get the system time Server_time_x of this solicited message;
In the present embodiment, N is 6,, within the window time, gets altogether the matching request information of 5 terminals.
Wherein, tw is the maximum in end delay time of A, B, C, D, E, six users of F.
In the present embodiment, N is 6, suppose topic establish residue 5 users solicited message plenary session appear within the window time,Get altogether the matching request information of 5 terminals.
Certainly, also have other user G, H, I etc., solicited message there will not be in the window time of A tw.
Step 405, divides according to the network-induced delay of the system time of these 5 terminals and these 5 terminals of getting in advanceDo not calculate the request time Ask_time_x of these 5 terminals;
Step 406, the one by one absolute value of the request time difference of the request time of these 5 terminals and first terminal relatively| whether Ask_time_x-Ask_time_1| is greater than predetermined threshold value;
The present invention is preferred, and predetermined threshold value is set as to 0.2 second. Certainly can also be shorter, no longer than 0.5 second.
Suppose that the request time of C and D and the request time absolute difference of A are greater than 0.5 second, exceed predetermined threshold value:
Step 407, coupling A and B, E, F.
If the request time difference of B, C, D, E, six user's request times of F and A is all greater than 0.5 second, not at default thresholdIn value, it fails to match to notify first terminal A.
Again receive the matching request information of first end.
As shown in Figure 5, before above-mentioned steps 407, also comprise:
Step 501, obtains the GPS information of the terminal that meets time match condition and the GPS information of first terminal;
That is, obtain the GPS information of B, C, D, E, six user's requests of F, and the party A-subscriber's who obtains in advance GPS comparison,Find that E and F and A be not in a geographic area, thereby, in step 407, only need to mate A and B.
Step 502, according to the GPS information of the GPS information of the described terminal that meets time match condition and first terminal, willDo not stop mating in the terminal of the time match condition that meets of the same area with described first terminal.
Or, as shown in Figure 6,
Step 601, obtains the IP address information of the terminal that meets time match condition and the IP address information of first terminal;
Step 602, does not stop the IP address of IP address and first terminal to mate at a regional terminal.
