Abstract

The invention discloses a method for browsing a decoded ticket file. The method comprises the steps as follows: a client transmits a ticket file list to be decoded to a server according to a communication protocol format of the client and the server; the server analyzes a decoding request of the client, obtains a decoding file list and a decoding inquiry condition, transfers a ticket decoding library to decode the requested ticket file, and stores the decoding result into a temporary file of the server; the server returns the ticket of the decoding result to the client for the first time; the client receives the first returned decoding result, calculates to-be-displayed total page number of the decoded ticket and displays the ticket of the first page; meanwhile, the server builds an index for the temporary file of the decoding result according to the ticket quantity displayed in each page by the client when the server returns the first page of information to the client. The geometric improvement of the system performance is achieved under the condition of building the index through a separating request of the client and the temporary file of the decoding result, and browsing multiple ticket files.

Description

A kind of decoding CDR file method of browsing

Technical field

The present invention relates to Computers and Communication field, particularly a kind of decoding CDR file method of browsing.

Background technology

In communication charge system, analyze and check charge information, need to decode to CDR file, the decoded file content of original bill files is the more than 8 times of former ticket, data traffic in simultaneous communication system is large, Yi Ge prefecture-level city is in the busy stage of communication, the CDR file that system hour produces reaches tens G bytes, after the CDR file decoding of hour, will reach hundreds of G byte, the ticket information of decoded this hundreds of G byte, service end is directly passed to client, client is carried out loaded and displayed, will there will be following two serious problems:

1. the time that service end transmits decoded result to client is very long, and the network bandwidth is taken greatly;

2. client loads very long, the so large data volume of ticket time of decoded result, causes, in client loading procedure, directly dying;

Based on above reason, general solution is that service end is carried out cutting decoding file, then result is sent to client in batches, client is separated loading to decoded result, although this scheme has solved client and has loaded the problem that decoded result is died, but performance is very low, cause in the CDR inquiry function of large ticket and big data quantity substantially unavailable.

Summary of the invention

For problems of the prior art, the object of the invention is to propose a kind of client and separate that request, service end are set up index to decoded result and paging transmits decoded result to client according to client demand, can solve the difficult problem that charge system is browsed large file and browsed large-data documents, charge system is when checking the CDR file of big data quantity simultaneously, also there is very high performance, the decoding CDR file method of browsing that system stability is high.

In order to achieve the above object, the present invention by the following technical solutions: a kind of decoding CDR file method of browsing, step comprises:

1) the client condition of CDR file of need to decoding, and condition is organized into syllable sequence according to protocol format, and sending inquiry request command to service end, CDR inquiry request protocol form is binary sequence, condition by two bytes of 0x070x07 separately, performs step 2 afterwards);

2) service end receives inquiry request, request command is decoded, obtain inquiry request condition, then according to the time conditions in inquiry request, select the CDR file of the time that meets, file is decoded, obtain ticket, the condition of user that client arrives input, when ticket meets the condition of inquiry request, writes temporary file ticket by row, perform step afterwards 3), otherwise directly perform step 3);

3) when decoding finishes, perform step 4), otherwise execution step 2);

4) temporary file is set up to index, service end reads every page of configuration that shows ticket number of client, obtains every page of value N that shows ticket number of client, set up the mapping buffer area CacheM of ticket position CDRPos in page number sequence number PageIndex temporary file corresponding to the page number, CDR file is read in advance, to the CDR file line number Row reading and N delivery, when the value of mould is 0, set up the map example of position CDRPos in a page number sequence number PageIndex and ticket place file, this example is put in CacheM, page number sequence number PageIndex adds 1 simultaneously, by this mode reading in advance, ticket decoded result temporary file is set up to index by page, perform step afterwards 5), otherwise directly perform step 5),

5) after phone bill decoding result temporary file is set up index and is completed by page, to client query request, return to Query Result, the protocol format returning results is: the ticket of every page of demonstration of the total line number CDRTotalRows0x070x07 of ticket is counted PageCDRRows0x070x07 one page ticket writing data, client calculates by CDRTotalRows or PageCDRRows the client that current inquiry request obtains and shows the total page number that ticket needs, at client initialization Pagination Display interface and show perform step afterwards 6 by first page ticket);

6) user clicks in client needs to show after the page number that ticket is corresponding, and the message that client transmission comprises page number information is to the call bill data of this page of service end request, and request protocol form is: the command code 0x070x07 page number number; Service end is received solicited message, the analysis request data acquisition page number number, by the page number number, from CacheM region of memory, obtain the mapping of the Data Position of this page CDR file corresponding to the page number in temporary file, by mapping, obtain the physical location IndexPos of this page of CDR file in temporary file, service end process is opened temporary file, move position is to IndexPos, read PageCDRRows jargon forms data, the data that read are turned back to client, and client is resolved the call bill data getting and is shown.

Adopt after technique scheme, the present invention has following beneficial effect: separately request of client of the present invention, service end are set up index and according to client demand paging, to client, transmitted the method for decoded result decoded result, not only solved the difficult problem that charge system is browsed large file and browsed large-data documents, charge system is when checking the CDR file of big data quantity simultaneously, also have very high performance, and system stability is high.

Embodiment

According to Figure of description and specific embodiment, the present invention is further explained below.

As shown in Figure 1, a kind of decoding CDR file method of browsing, step comprises:

2) service end receives inquiry request, request command is decoded, decoded result writes in the temporary file of service end, every ticket is write a line, temporary file to decoded result is set up index, obtain inquiry request condition, then according to the time conditions in inquiry request, select the CDR file of the time that meets, file is decoded, obtain ticket, the condition of user's input that client arrives, when ticket meets the condition of inquiry request, ticket is write to temporary file by row, performs step afterwards 3), otherwise directly perform step 3);

3) when decoding finishes, perform step 4), otherwise execution step 2);

4) temporary file is set up to index, service end reads every page of configuration that shows ticket number of client, obtains every page of value N that shows ticket number of client, decoded result has M bar ticket, every page of demonstration N bar ticket of client, and index segment records number and is: X=M/N, service end internal memory is set up a mapping relations Map sequence of preserving position in index segment and every page of ticket place temporary file, in every page of ticket place temporary file, position account form is: by row, read temporary file, record reads the singly position in temporary file of every jargon, set up the mapping buffer area CacheM of ticket position CDRPos in page number sequence number PageIndex temporary file corresponding to the page number, CDR file is read in advance, to the CDR file line number Row reading and N delivery, when the value of mould is 0, set up the map example of position CDRPos in a page number sequence number PageIndex and ticket place file, this example is put in CacheM, page number sequence number PageIndex adds 1 simultaneously, by this mode reading in advance, ticket decoded result temporary file is set up to index by page, perform step afterwards 5), otherwise directly perform step 5),
