In the prior art, because cash register link only carries out whole payment capacity current-limiting, cause when big flow pays peak value,
Each means of payment capacity cannot be fully utilized.
The present invention joined preposition means of payment granularity current limliting in cash register link, and recommend the idle means of payment to user,
So as to make full use of the various means of payment.The present invention also perceives downstream means of payment volume change situation (for example, bank card
Abnormal, the capacity of bank card channel can reduce), and the user for being most suitable for by current limliting and recommending other means of payment is selected, it mentions
It rises user to pay success rate and reduce user's switching rate, ensures that user's payment is smooth.
Specific embodiment
For the above objects, features and advantages of the present invention can be clearer and more comprehensible, below in conjunction with attached drawing to tool of the invention
Body embodiment elaborates.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, but the present invention can be with
It is different from other way described herein using other and implements, therefore the present invention is by the limit of following public specific embodiment
System.
In network payment, whether the payment of user is smooth, and there are two measurement indexs: payment success rate and user pay work
Has switching rate.
Payment success rate is to pay successfully several ratios with payment request number.User's means of payment switching rate is user's switching
The ratio between payment number and payment request number of the means of payment.In general, payment success rate is higher, user's means of payment switching rate more
Low, the smooth degree of payment is higher.
The application is intended to provide a kind of method that payment smooth degree is promoted in the case where integrally paying off-capacity.
Fig. 1 is the schematic diagram for paying link capacity current limliting scheme, and Fig. 2 is the stream for paying link current limliting process in the prior art
Cheng Tu.
As illustrated in fig. 1 and 2, there are two links for payment link: cash register link and payment link.
Specifically, initiating transaction request (being also referred to as payment request herein) (for example, clicking the " true of Taobao in user
Subscribe buy/submit order " button) after, cash register link can be entered.In cash register link, using jumping out cashier interface, cashier
The several means of payment of interface display prompt user that one of means of payment is selected to pay.Alternatively, cashier interface
It can show the default means of payment and select the entrance of other means of payment.The means of payment and point that user's determination will be used to pay
It hits after " confirmation payment " button, into payment link.
Correspondingly, the transaction request capacity current-limiting of payment chain road is divided into following two node:
First node is cash register link current limliting, and also referred to as whole current limliting is carried out for whole transaction request flow
Current limliting protects entire payment link.When trading peak value, transaction request sum can be greater than the total capacity of payment channel.Cash register ring
Section current limliting allows the transaction request of the quantity less than or equal to payment channel total capacity to enter cash register link, other friendships by current limliting
Easy request queue, which waits, enters cash register link.Whole current limliting carries out current limliting generally according to the time for receiving transaction request, later
The request received is more likely by current limliting.Therefore the means of payment requested in whole current limliting by current limliting are unable to control.
Second node is payment link current limliting (also referred to as dividing means of payment current limliting).Into after payment link, system root
Current limliting is carried out respectively according to various means of payment capacity.Specifically, a capacity threshold is arranged for every kind of means of payment, if choosing
The number of users for selecting the means of payment is greater than the capacity threshold, then system only allows the transaction of the quantity equal to the capacity threshold to ask
It asks into paying, other transaction requests are waited in line.
In some instances, wait in line to be more than threshold time, then Fail Transaction.
Fig. 3 illustrates an example of payment link current limliting in the prior art.
As shown in figure 3, four kinds of means of payment A, B, C and D can be used in transaction, these means of payment may, for example, be bank
Card, flower, Yuebao, Alipay remaining sum etc..
These transaction requests include 60,000 using means of payment A request, 60,000 using means of payment B request, 20,000
A request that means of payment D is used using the request of means of payment C and 20,000.It note that corresponding to each request here
The means of payment are the default means of payment that system is determined according to the setting of the user of the request and/or payment habit etc..For example, logical
It is often shown as the default means of payment on cashier interface, or makes number one in means of payment list.That is, being handed in request
In easy user, there are 60,000 user's defaults using means of payment A, 60,000 user's defaults use means of payment B, 20,000 users
Default uses means of payment D using means of payment C and 20,000 user's defaults.For simplicity, these requests are herein
It is middle to be also referred to as means of payment A request, means of payment B request, means of payment C request and means of payment D request respectively.It should recognize
It arrives, quantity given here is only exemplary, and is not intended as limiting.
In the example of fig. 3, the whole volume of cash register link is limited to 80,000.After capacity current-limiting by cash register link,
30000 kinds of means of payment A requests, 30,000 kinds of means of payment B requests, 10,000 kinds of means of payment C requests and 10,000 kinds of means of payment D are asked
It asks through current limliting, into payment link.Remaining transaction request is waited in line through cash register link current limliting.
In payment link current limliting, current limliting is carried out respectively to various means of payment capacity.As shown in figure 3, in payment link
It is respectively 20,000,40,000,10,000 and 10,000 for tool A, B, C and D capacity threshold defined.Pass through the payment work of cash register link current limliting
The quantity (30,000) of tool A request is greater than the capacity threshold (20,000) that payment link defines tool A, is thus left 10,000 payment works
Have A request to need to be lined up in payment link, causes these users and pay time-out or failure.And pass through the branch of cash register link current limliting
The quantity (30,000) for paying tool B request is fewer by 10,000 than the capacity threshold (40,000) that payment link defines tool A, thus leads to 10,000
A means of payment B capacity is unutilized, causes the wasting of resources.It can be seen that the distribution of prior art means of payment current limliting is led
The unbalanced of resource allocation is caused.
Payment smooth degree is promoted in the case where integrally paying off-capacity in view of the above problems, the invention proposes one kind
Method.Specifically, being added on the basis of whole current limliting in cash register link current limliting and dividing means of payment current limliting and payment work
Tool is recommended.For example, capacity of the system according to every kind of means of payment is adjusted flexibly each on the basis of whole volume meets limit
The accounting distribution of the kind means of payment.This can recommend the branch of downstream payment smoothly by the user overloaded to the default means of payment
The tool of paying is reached.For example, the more idle means of payment that guidance user is had higher success rate using payment, it is whole thus to improve user
Body payment success rate simultaneously reduces user's means of payment switching rate, and resource is efficiently utilized.
Fig. 4 illustrates the example of the payment link current limliting of various aspects according to the present invention.
As shown in figure 4, cash register link can be divided into two stages.In the first stage, whole current limliting is carried out to payment request,
It is identical as shown in Fig. 3.
Difference from prior art is that the present invention is added to second stage in cash register link, is every in second stage
A target value is respectively set in the kind means of payment, which can be arranged according in continuation payment link current limliting for the means of payment
Capacity threshold be arranged, and the sum of target value of every kind of means of payment meets the entirety of (that is, being less than or equal to) cash register link
Capability value.
For the sake of explaining conveniently, in this example, cash register link second stage is the target of every kind of means of payment setting
Be worth with payment link is that the capacity threshold that every kind of means of payment are arranged is identical, but cash register link is the mesh of every kind of means of payment setting
Scale value can also be different with the capacity threshold that payment link is the setting of every kind of means of payment.For example, in the whole of cash register link
In the case that body capacity is bigger, the target value of cash register link can also be greater than the capacity threshold of payment link, for example, cash register link
Target value can for payment link capacity threshold bi-directional scaling.
Further, cash register link second stage is that the target value of every kind of means of payment setting can be adjusted dynamically.System can
To perceive the volume change situation of each means of payment in downstream.For example, banking channels shake extremely will lead to bank's capacity and become smaller, by
This to pay the capacity threshold reduction that link current limliting node is bank card setting.In such a case, it is possible to accordingly decrease
For the target value of bank card setting in cash register link.
As shown in figure 4, having 60,000 kinds of means of payment A requests, 60,000 kinds of means of payment B requests, 20,000 kinds of payments in transaction request
Tool C request and 20,000 kinds of means of payment D requests.
After whole volume current limliting by the cash register link first stage, 30,000 kinds of means of payment A requests, 30,000 kinds of payment works
Have B request, 10,000 kinds of means of payment C requests and 10,000 kinds of means of payment D requests by current limliting, into the second-order of cash register link
Section is identical as shown in Fig. 3.
In this example, target value 20,000,40,000,10,000 and 1 is respectively set to four kinds of means of payment in cash register link second stage
Ten thousand.It can be seen that means of payment A requests (30,000) than means of payment A target value (20,000) mostly 10,000, and means of payment B requests (3
Ten thousand) fewer by 10,000 than means of payment B target value (40,000).
Thus system can determine that means of payment A is the means of payment of overload, and means of payment B is more idle payment work
Tool.System, which can further determine that, to recommend means of payment B to some users of means of payment A.
In the second stage of cash register link, system selects 1 in the user of 30,000 means of payment A according to various proposed algorithms
General-purpose family is recommended to use more idle means of payment B to these users.The proposed algorithm be for example considered that user habit,
History pays success rate, waiting time, etc..
Fig. 5 shows the surface chart that the means of payment are recommended to use to user.Preferably, recommend the boundary of the means of payment to user
Face figure can show that estimated queue time considers whether to switch for user.
In the ideal case, after the recommendation step by cash register link, 10,000 users using means of payment A are changed to
Selection is paid using means of payment B.As a result, eventually by cash register link current limliting being that 20,000 kinds of means of payment A are asked
It asks, 40,000 kinds of means of payment B request, 10,000 kinds of means of payment C requests and 10,000 kinds of means of payment D requests, into payment link.
In payment link current limliting, current limliting queuing is eliminated, overall payment amount improves 10,000 compared with prior art.
Recommend about the means of payment, system can pay habit according to user, history pays success rate, waiting time etc.
The means of payment for recommending other idle because usually determining to select which user in using the user of the overload means of payment, thus
Reduce user's means of payment switching rate.
For example, system can be in defaulting user using means of payment A to using the higher user of means of payment B frequency
It is recommended to use means of payment B, so as to improve the success rate of recommendation.Alternatively, the history that system can be paid according to user
Success rate is recommended the means of payment to user, for example, some users are higher (for example, on bank card using the success rate of bank card
Remaining sum it is more sufficient), then can be recommended to use bank card to these users.
It illustrate only the example for recommending a kind of means of payment in the example of Fig. 4 and Fig. 5 although note that, at two kinds
Or more the above means of payment it is more idle in the case where, the means of payment of two or more can also be recommended to user, pushed away
The sequence recommended is referred to the historical success rates that user pays habit or user's payment.
Enter payment link by the payment request of cash register link, payment link is that every kind of means of payment define a capacity
Threshold value, the capacity threshold can be determined according to downstream means of payment volume change.Cash register link current limliting is directed to every kind of means of payment
Current limliting is carried out to transaction request, allows the payment request of the capacity threshold less than or equal to the means of payment to pass through, into payment
Link, the payment request needs beyond capacity threshold are waited in line.
Fig. 6 illustrates the flow chart of the means of payment current-limiting method of various aspects according to the present invention.
In step 601, the transaction request from multiple users is received, includes at least requests transaction in these transaction requests
User identity (ID).
In step 602, according to the requirement of the first current limliting node (for example, cash register link current limliting node) to these transaction requests
Carry out whole current limliting.
For example, step 602 can correspond to the first stage of above-mentioned cash register link.
Specifically, the transaction request being only capable of in the first current limliting node through a certain number of thresholds can be limited to.Remaining
Transaction request needs are waited in line through the first current limliting node.
In step 603, main payment work relevant to the whole user of each request of current limliting is passed through is determined according to User ID
Tool.
The main means of payment can be the default means of payment that the user stored in system uses.Specifically, system can
Think that each user stores its corresponding default means of payment, which can be user oneself setting, can also
To be that system is determining according to user's payment habit.System can be searched according to User ID in its memory to determine and be somebody's turn to do
The default means of payment of user.
In step 604, the number of transaction request corresponding to every kind of means of payment is counted.
It is every kind of means of payment setting according to the second current limliting node (for example, payment link current limliting node) in step 605
Capacity threshold is arranged the target value of counterpart expenditure tool in the first current limliting node.
The target value can be arranged according to being the capacity threshold of means of payment setting in continuation payment link current limliting, and
And the sum of target value of every kind of means of payment meets the whole volume value of (that is, being less than or equal to) cash register link.
In step 606, the transaction request quantity of every kind of means of payment is compared with the target value of the means of payment, with
Determine the overload means of payment and the idle means of payment.
For example, the means of payment that transaction request data volume is greater than target value are confirmed as the means of payment that overload, and trade and ask
The means of payment for asking data volume to be less than target value are confirmed as the idle means of payment.
In step 607, the idle means of payment are recommended to use to user relevant to the overload means of payment.
As shown in fig. 6, user can be prompted to use the payment higher means of payment of success rate on the mobile phone interface of user.
In step 608, current limliting is carried out to transaction request for every kind of means of payment in the second current limliting node.
Step 603-608 can correspond to the second stage of above-mentioned cash register link.
In step 609, payment link will be sent to by the transaction request of the second current limliting node.
Second current limliting node (for example, payment link current limliting node) is that a capacity threshold is arranged in every kind of means of payment.The appearance
Amount threshold value can dynamically be adjusted according to downstream means of payment volume change.Second current limliting node is limited for every kind of means of payment
Stream allows the payment request of the capacity threshold less than or equal to the means of payment to pass through, and into payment link, exceeds capacity threshold
Payment request needs wait in line.
Note that it is above describe flow chart according to certain order, but the order of these steps is also commutative.For example, step
The target value of every kind of means of payment of setting in rapid 605 can also be before any one of step 601,602,603 and 604.
Fig. 7 shows the flow chart of the means of payment current-limiting method of various aspects according to the present invention.
In step 701, the transaction request from multiple users is received.
In step 702, the transaction request of first threshold number is made to pass through the first current limliting node.
In step 703, the means of payment relevant to each transaction request of the first current limliting node is passed through are determined.
In step 704, determine that the main means of payment relevant to each transaction request of the first current limliting node is passed through are the free time
The means of payment still overload the means of payment.
For example, if the quantity of transaction request relevant to the means of payment is lower than the predetermined target value of the means of payment,
The means of payment are determined for the idle means of payment, if the quantity of transaction request relevant to the means of payment is higher than the means of payment
Predetermined target value, it is determined that the means of payment be overload the means of payment.The predetermined target value can be according to second limit
It determines and can be become according to the capacity of every kind of means of payment for the capacity threshold of every kind of means of payment setting at stream node
Change and carrys out real-time update.
In step 705, recommend the idle means of payment to the subset for the user that the main means of payment are the overload means of payment.
Preferably, using overload the means of payment user subset be according to user's use habit and/or history payment at
Power carrys out selection.
In step 706, current limliting is carried out to transaction request for every kind of means of payment at the second current limliting node.
Second current limliting node (for example, payment link current limliting node) is that a capacity threshold is arranged in every kind of means of payment.The appearance
Amount threshold value can dynamically be adjusted according to downstream means of payment volume change.Second current limliting node is limited for every kind of means of payment
Stream allows the payment request of the capacity threshold less than or equal to the means of payment to pass through, and into payment link, exceeds capacity threshold
Payment request needs wait in line.Payment link is sent to by the transaction request of the second current limliting node.
