Problems solved by technology

This method needs to be searched in the entire file, which is related to performance and file size. The performance is still possible if the volume of bills is small, but it may be affected if the volume is large.
[0006] Pure-memory method: Run the duplicate check files in memory. This method does not rely on the functions provided by the database, and the processing speed is fast, but the number of duplicate check files is large. In addition to occupying part of the hard disk storage resources, it also requires system There are relatively large memory resources, and there are relatively strict requirements for the host memory when processing a large number of bills

Embodiment Construction

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] Such as figure 1 As shown, the method for removing duplicates from the call list of the present invention comprises the following steps:

[0030] Step 1: Read the current bill information and obtain the business type of the current bill;

[0031] Step 2: According to the type of business obtained, select the deduplication business group of the current bill;

[0032] Step 3: according to the call time of the current bill, locate the time period corresponding to the current bill in the duplicate removal service group;

[0033] Step 4: According to the call time of the current bill, continue to locate the time zone corresponding to the current bill in the time segment located in step 3;

[0034] Step 5: Write...

Abstract

The invention relates to a repeated ticket removing method. The method comprises the following steps of: 1, reading the current ticket information and acquiring a service type of the current ticket; 2, selecting a repetition removing service group of the current ticket according to the service type; 3, positioning the repetition removing service group to a time slot corresponding to the current ticket according to conversation time of the current ticket; 4, continuously positioning to a time subarea corresponding to the current ticket in the time slot according to the conversation time of the current ticket; and 5, writing the existing ticket in the time subarea into an internal memory, comparing the existing ticket with the current ticket, if the existing ticket is the same as the current ticket, determining that the current ticket is a repeated ticket, and if the existing ticket is different from the current ticket, combining the current ticket with the existing ticket to generate a new existing ticket. By the method, index files are grouped according to services, are sectioned and partitioned according to time, and have small occupied internal memory, a small amount of input / output (IO) operation compared with that of the conventional repetition removing program and processing capability with high capacity and high performance, and processing performance is unrelated to data volume.

Description

technical field [0001] The invention relates to a deduplication method for the same bill records, in particular to a method for solving the file-level deduplication of massive files in the telecommunication system. Background technique [0002] With the extensive development of telecom operators' business, various new services emerge in an endless stream, and various business bills emerge in endlessly; with the decline of telecom charges and the growth of customer base, the number of calls of users is also increasing year by year, and the number of detailed bills of users is on the order of magnitude Often exceeds 100 million. [0003] Deduplication of massive data has become a problem that operators must solve. At present, major operators mostly adopt database, memory and file system methods. These methods have more or less defects in performance and IO when processing massive data. [0004] Database method: The specific method of using the unique index technology of the ...
