Embodiment
The embodiment of the invention provides CDR date storage method, display packing and system, for making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail
Referring to Fig. 1, in an embodiment of the present invention, the method that the embodiment of the invention provides of realization may further comprise the steps:
Step 101: obtain the CDR data.
Step 102: the described CDR data of each class are told four subfiles.
The difference of data based self agreement of the CDR after synthetic has different types, as the CDR data of CDMA, and A11 type CDR data etc.Each class CDR data generates four subfiles, distinguishes with four kinds of different suffix names respectively, is respectively:
*.cdr, be used for depositing the CDR essential information, all central fields require isometric, help filter operation;
*.apd, be used for depositing the additional information of each bar CDR, for example corresponding data package location or the like;
*.dat, be used for depositing in raw data packets or superpacket;
*.map, be used for depositing the index of file content;
Wherein, " * " represents four filenames that subfile is identical, and these four subfile mutual group become a CDR file group of finishing, and are interrelated between four subfiles, when the user need copy or be mobile, are that whole file group is operated simultaneously.
Step 103: described four subfiles are write storage medium.
Four subfiles will write the storage that storage medium just can be finished the CDR data after generating.
Four subfiles all can be write disk; Perhaps will
*.cdr write database, and three subfiles will being left write disk.
Below the structure of four subfiles is introduced one by one.
The subfile that with cdr is suffix is called the CDR file, is made of CDR header file and CDR data division.
Each CDR file all has the header file of oneself, referring to table 1, comprising timestamp.The purpose of doing like this for later on according to the time period CDR data are retrieved be convenience with quick.

Wherein, CDR_ID is the unique identification of CDR, when creating, CDR produces, and be the unique identification of this CDR in whole life cycle.
For the content of each field is better understood, explain several notions here, promptly synthetic CDR and agreement CDR.
CDR is divided into synthetic CDR and agreement CDR from synthetic scope.Give an example below these two notions are described: device A is made a phone call to equipment B, the centre must be via equipment C, the communication protocol that adopts between A and the C is Proto AC, the communication protocol that adopts between B and the C is Proto BC, CDR person between CDR between A and the C and B and the C is agreement CDR so, they have only described the communication process between adjacent two equipment, with the CDR between A-C, the C-B combine (being associated together) just formed synthetic CDR, it described device A to equipment B the full call flow process.Obviously, in such cases, synthetic CDR is the higher level CDR of agreement CDR, and agreement CDR is the CDR of subordinate of synthetic CDR.
So the FILE_CDR_ID of the FILE_ID of higher level CDR and higher level CDR just is meant with respect to the FILE sign of the upper level CDR of current C DR and the ID of corresponding higher level CDR in the table 2.
The subfile that with apd is suffix is a CDR accessory information file, comprises the attachment data district of header file and CDR.
The accessory information of CDR comprises other not isometric information fields that initial data package informatin, higher level CDR position, this CDR deposit and other additional informations of this CDR correspondence.
Wherein, the initial data package informatin specifically comprises: the information of packet number and each packet, and the information of each packet comprises: the position of the decoding interpretative version string of the position of packet in the packet file, this packet and the CDR of subordinate of this packet correspondence.
Higher level CDR position comprises: the index of this CDR place file and the index of this CDR in file.
Subordinate CDR position comprises: the index of this CDR place file and the index of this CDR in file.
With dat be suffix be the packet file of CDR data, comprise file header and packet information two parts.
Information such as original, the association that the store data bag is relevant in each packet information, the content that the packet of agreement CDR and non-agreement CDR is deposited is different.

Table 3 is the packet file of agreement CDR correspondence, table 4 is the corresponding packet file of upper strata CDR (non-agreement CDR), from table 3 and table 4 as can be seen, what deposit in the packet file of agreement CDR correspondence is the original data message of packet, what deposit in the packet file of higher level CDR correspondence is the position of packet entity, is the location index of packet name and this packet.
No matter it can also be seen that from table 3 and table 4, be agreement CDR or the higher level is CDR, all preserved the position of this layer CDR in the pairing packet, its objective is in order to realize that packet is to the index between the CDR file (promptly being the file of suffix with cdr).
The subfile that with map is suffix is the CDR index file, and the index that is used for depositing the CDR file closes and the index relative of packet file.
The CDR index file comprises file header and CDR file index table and packet file index table.
After according to preceding method the CDR data being stored, as shown in Figure 2 interrelated between the CDR specifically comprises:
1., higher level's (N level) CDR packet is searched data entity: the file ID and the file index position of having deposited the packet entity in the higher level CDR packet, at first obtain the position of packet entity, obtain the packet entity according to the incidence relation 12 between the entity content in location index in the packet and the N+1 level packet then by the incidence relation 4 between packet index position and the database file concordance list.
2., search corresponding packet from CDR: if agreement CDR, as the N+1 level CDR among Fig. 2, at first find the corresponding raw data file name of CDR file data part, find the pairing deposit data of this CDR position according to the incidence relation 1 between the original packet information in CDR data division and the CDR additional information files, carry out reading of data by the incidence relation 2 between original packet information in the described CDR additional information files and the packet file data package informatin then.
It should be noted that: if synthetic CDR, for example be N level CDR, what find by the incidence relation 2 between original packet information in the described CDR additional information files and the packet file data package informatin is the position that the packet entity is deposited, also should continue to search the entity of this data correspondence, the description during 1. method sees.
3., CDR from the data search correspondence: at first according to the incidence relation 3 between packet file and the CDR index file, use the index FILE_ID of corresponding this layer CDR place file in CDR file index table, to find corresponding filename, according to the incidence relation 5 of packet file and CDR file data part, find corresponding CDR then in conjunction with CDR_ID.
4., the CDR of subordinate searches higher level CDR: each CDR has deposited the position of corresponding higher level CDR in its additional information, be the FILE_ID+CDR_ID that incidence relation 6 between data division and the accessory information file finds the pairing higher level CDR of CDR at first by the CDR file, find the filename of the pairing higher level CDR of FILE_ID then by the incidence relation between accessory information file and the index file 7, add that by the filename that obtains CDR_ID finds corresponding higher level CDR through the incidence relation 8 between additional information files and the higher level CDR file data part.
5., higher level CDR packet is searched the CDR of subordinate: each packet among higher level CDR all might corresponding CDR of subordinate, find corresponding data to wrap in FILE_ID and CDR_ID among the CDR of subordinate by the incidence relation 9 between higher level CDR file data part and the higher level CDR accessory information file, is a concrete CDR filename with FILE_ID by incidence relation 10 index between higher level CDR additional information files and the higher level CDR index file, adds that then CDR_ID finds the CDR of subordinate by the incidence relation 11 between higher level CDR additional information files and the CDR of the subordinate file.
It should be noted that agreement CDR does not have packet file index table.
As can be seen from Figure 2, after the CDR storage being four subfiles, because interrelated between four subfiles, so can realize between the CDR of the superior and the subordinate data and the index between the subfile of CDR data at the corresponding levels and searching according to aforesaid method.
