103A, when the type of the data is a first data type, acquiring the priority of the data according to the channel and media of the data;

103B, pushing the data according to the priority of the data.

Determining to acquire channels and media of new customers for the new customer data, and carrying out priority ranking and pushing to an operator; different strategies are also adopted for old customers to push to the salesman. Specific examples are as follows:

and determining to acquire the channel and the media of the new customer for the new customer data, and carrying out priority ranking and pushing to the salesman.

The prioritization may be performed according to information such as confidence, reliability weight, and customer's back tone of the channel for obtaining customer information, or may be performed according to whether the customer's information is complete, for example, the priority may be advanced for a channel for obtaining customer information with incomplete customer information and later priority, and for a channel for obtaining customer information with high confidence and high reliability weight.

For example, for regular channels and media, it is more for premium customers; in addition, for loan transactions, the demand for companies such as the boss or the customers who need to use money is high, and the customers are ranked higher.

The channels and media comprise the information related to the official documents, the letters, the briefings, the reports, the telephones, the telegrams, the faxes and the e-mails which are received every day in the daily work channel; the internet channel refers to each large search website, and the mass media channel refers to information on broadcasting, television, newspapers, magazines and books. Or data provided by a third party, such as a house property transaction website client application registration information and the like.

The specific method comprises the steps of collecting and summarizing information of mobile phone numbers, contact time, contact channels, contact contents, user feedback and user acceptance degrees from a plurality of information channels to a client; once the mobile phone number and the contact content in the element are found to be the same, the information is judged to be repeated, all information of the same number with the earliest contact time is deleted according to the contact time, and only the content information with the latest contact time is reserved; storing the customer information collected by a plurality of information channels by using a combination mode of mobile phone numbers, contact time, contact channels, contact contents, user feedback and user acceptance; and archiving the customer information according to the contact content.

Fig. 3 shows a schematic flow diagram of a data pushing method according to an embodiment of the present invention, as shown in fig. 3, after step 102 in fig. 1, when the type of the data is the second data type, the method pushes the data according to different situations, which may be preset, and when the type of the data is the second data type, the method may include the following situations:

104. and when the type of the data is a second data type, pushing the data according to the updating time of the data.

In the embodiment, the data is pushed according to the updating time of the data, so that the pushing that the updating time is closer to the current time is ensured, and the condition that the important information of the client is missed is avoided, such as the information of the loan renewal time due and the renewal time of the old client.

In another implementable manner, as shown in FIG. 4:

105. when the type of the data is a second data type, comparing the data with data corresponding to the identifier of the data in an original data table according to the identifier of the data, updating the data corresponding to the identifier of the data in the original data table, and determining the priority of the data according to the data of a target item of the data;

as shown in table 1 below, when the ID is changed to be 123, only the expiration date in the original data table needs to be changed, at this time, the ID is obtained in the original data table, and then the existing data is compared with all items corresponding to the ID, and only the expiration date is updated in this embodiment.

TABLE 1

ID	Contact means	Item	Due date
				123	186XXXXXXX	Item A insurance	201XXXX

106. And pushing the data according to the priority of the data.

It can be understood that, for example, if the data of the target item is that the loan service expiration time is 2018.6.1, the target value is 2018.4.20, and the preset threshold is 10 days, then a notification of loan service renewal needs to be sent to the identifier (mobile phone number) corresponding to the data, and the notification may be a telephone communication prompt, a short message prompt, a mail prompt, or the like. In general, push policies for old customer data:

A. the priority of the data update time closest to the current time is the largest,

but in a special case when the data updating time is closest to the current time, the priority level is ranked last, and the updated data is comprehensively referred, for example, the current data updating time is less than 10 minutes from the current time, the priority level is ranked first, but the content of the updated data is the target information of the client, wherein the target information comprises loan settlement completion information, non-continuous loan information, client clear non-cooperation information and the like, and if the information is met, the ranking is ranked behind the data of the old client directly, and the priority level is ranked later.

B. The users who acquire the loan duration in the old customer data and expect the renewal and the like or the users waiting for the renewal are sorted according to the time priority.

The schemes A and B can be divided into priority levels or can be weighted in parallel, the specific priority order is not limited, and various schemes can be provided.

Regarding the data update of the old customer, one way is to update the data of the old customer in time, for example, the mobile phone number changes, the communication address changes and the like to ensure that the customer can normally contact; or the client has other added loan services and the like, and timely additional recording and tracking are performed, including but not limited to the following data updating.

The updated data of the old client will be prioritized and ranked later and earlier than the new client push.

And for old customer data, comparing the acquired data with the old customer data, and performing supplementary updating in an incremental coverage mode.

The updating may include: such as the contact information of the customer, the customer's requirements, other added services, etc.

Regarding the data updating of old customers, the second mode is to distinguish the guest group tags, push short messages according to different guest group tags, and recycle and update the list through the customer reply data.

The customer group label can be a source label of a customer, such as a label of a push media or a label of an introducer, and can also be understood as a label of an operator serving the customer, so that the label is pushed to the corresponding operator in a more targeted manner, and under the conditions that the operator leaves or is not on duty, the label of other operators in the same group as the operator can also be pushed, so that data management is more convenient. And convenience for service personnel to maintain clients is also facilitated.

Such as an expiration time reminder for the customer's loan, a customer's continued loan, etc.

The method comprises the step of distinguishing the new customer from the old customer, so that the new customer can be obtained and the old customer can be maintained without the need of re-screening data by a sales clerk, and the working efficiency is improved. In addition, priority arrangement is carried out on the new customers, so that the probability of obtaining high-quality customers is improved; the data is updated for the old client, in addition, the data is acquired in a short message pushing mode, the list is recycled, and the list acquisition cost is reduced; the customer identification degree is improved, and the management is convenient; the hotness of the list is ensured, and the probability of forming the list is improved; the list information is rich enough, and the agents do not need to be collected repeatedly, so that the agent working efficiency is improved.
