Description
Technical field
The present invention relates to data and read technology, particularly method and the device of the quick access of a kind of CDF side offline bill data.
Background technology
The packet-based core networks of evolution (Evolved Packet Core, EPC) in offline charging ticket transmitting procedure, as charging data function (Charging Data Function, CDF) with Charging Gateway Functionality (Charging Gateway Function, when CGF), link is abnormal, CDF need to be stored in this locality by charging bill temporarily, when link-recovery, then by the ticket reading and sending of having stored to CGF.Conventionally, in telephone traffic between large and CDF and CGF in the unstable situation of link, there will be CDF frequent access ticket, access speed slack-off, thereby cause CDF total system processing power, decline, when serious, equipment failure can occur.
Describe in detail below.
EPC offline charging ticket is divided into three kinds conventionally in the storage scheme of CDF side at present: one, usage data library storage; Two, use file directly to store; Three, use the storage of buffer zone+file.
One, usage data library storage: when CDF need to store or read ticket, CDF application realizes by accessing database external interface (being generally SQL statement), each ticket is stored or is read, and all needs to call database interface one time, specifically consults shown in Fig. 1.
Yet, can there is following problem in the mode of usage data library storage: lower deployment cost is high, system overhead is large, store at every turn or read ticket, all need calling data bank interface, if database itself is not done Performance tuning, file input-output operation (Input Output, I/O) operation is just many, causes access performance not high.And the storage of this simple repetition, read operation, cannot give play to database in the advantage of the aspects such as inquiry, sequence, safety.
Two, use file directly to store: when CDF need to store or read ticket, CDF applies direct calling system file access interface is provided, each ticket is stored or is read, and all needs to call file write or read interface one time, specifically consults shown in Fig. 2.
Yet, can there is following problem in the mode of using file directly to store: lower deployment cost is low, system overhead is also little, but store at every turn or read ticket, all need calling system file write or read interface, when ticket quantity is more, obviously can cause file I/O operation too frequent, thereby cause the bottleneck of system performance.
Three, use the storage of buffer zone+file: when CDF needs memory ticket, when first ticket being put into ，Dang compose buffer, compose buffer completely or arriving duration thresholding, by the file one-time write storage area in compose buffer; When CDF need to read ticket, first by file disposable read and put into read buffer zone, and then by CDF application reading and sending ticket from read buffer zone, specifically consult shown in Fig. 3.
Yet, use the mode of buffer zone+file storage can have following problem: a plurality of tickets storages only need write-once file, a plurality of tickets only to read need once to read in file, greatly reduce like this file I/O frequency.But, time of compose buffer writing in files and the time that file reads in buffer zone has been included in to whole storage and has read in ticket process, and the speed of file I/O operation must be slower than ticket and deposits in and read ticket speed in Huo Congdu buffer zone, compose buffer, therefore, adopt in this way, can cause because the speed of file I/O operation is slow the bottleneck of system performance equally.

Embodiment
In telephone traffic between large and CDF and CGF in the unstable situation of link, for fear of cause CDF total system processing power to decline due to CDF frequent access ticket, in the embodiment of the present invention, adopt read-write double buffering+tetra-thread parallel to process, eliminated file I/O and operated slow performance bottleneck and can not wait for time delay because cross-thread source synchronous produces.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is elaborated.
Consult shown in Fig. 4, in the embodiment of the present invention, when between CDF and CGF, link is unstable, it is as follows that CDF carries out the detailed process of ticket storage:
Step 400:CDF chooses the first compose buffer, and adopts the first thread that the call bill data of acquisition is write to the first compose buffer.
Step 410: meet first when pre-conditioned until the use state of the first compose buffer, CDF switches to the second compose buffer, and adopt the first thread that the call bill data of acquisition is write to the second compose buffer, and adopt the second thread to deposit the call bill data of storing in the first compose buffer in storage area.
In the present embodiment, the use state of so-called the first compose buffer meets the first pre-conditioned referring to: the first compose buffer has been write full, or, the first duration thresholding of arrival systemic presupposition.
For example: consult shown in Fig. 5, in the present embodiment, suppose that CDF is provided with thread A(and is called again ticket storage thread), and thread B(is called again file and writes thread), concrete:
Thread A: for selecting an idle compose buffer, as shown in Figure 5, can select compose buffer 1, also can select compose buffer 2, what suppose to choose is compose buffer 1, and thread A deposits call bill data in this compose buffer 1 in, when full or the arrival of the first duration thresholding are write in compose buffer 1, thread A switches to compose buffer 2, continues call bill data to write in compose buffer 2, then notifies thread B to process the compose buffer 1 before switching.
Thread B: accept thread A and control, for the call bill data of writing compose buffer full or that the first duration thresholding arrives 1 record is write to storage area.
Certainly, when the call bill data in compose buffer 2 is write completely or again arrives the first duration thresholding, thread A also can switch to compose buffer 1 again, and notify thread B that the call bill data in compose buffer 2 is write to storage area, idiographic flow, to similar for the operation of compose buffer 1, does not repeat them here.
Further, consult shown in Fig. 6, optionally, in order to guarantee the fluency of overall flow, as long as thread B is set, the call bill data of record in compose buffer (compose buffer 1 or compose buffer 2) is all write to the required duration of storage area, be not more than thread A and call bill data write to the duration of full compose buffer (compose buffer 1 or compose buffer 2), or/and, thread B also can be set the call bill data of record in compose buffer (compose buffer 1 or compose buffer 2) is all write to the required duration of storage area, be not more than the first duration thresholding of setting, wherein, this the first duration thresholding carries out the time interval (above mentioning) of compose buffer switching for characterizing thread A, like this, can make thread A move continuously, and need not wait for that thread B writes storage area by call bill data, further guaranteed the fluency of operation, and further eliminated the system bottleneck causing slowly due to write operation when call bill data writes storage area.
Certainly, above-described embodiment only be take and is existed two compose buffers as example is introduced, and in practical application, if there is three and above compose buffer, can adopt equally thread A and thread B to write switching between each compose buffer, at this, also repeats no more.
Consult shown in Fig. 7, in the embodiment of the present invention, when between CDF and CGF, link-recovery is stablized, it is as follows that CDF carries out the detailed process that ticket reads:
Step 700:CDF chooses first and reads buffer zone, and adopts the 3rd thread that the call bill data in storage area is read to first to read buffer zone.
Step 710: meet second when pre-conditioned until the first use state of reading buffer zone, CDF switches to second and reads buffer zone, and adopt the 3rd thread that the call bill data in storage area is read to second to read buffer zone, and adopt the 4th thread to read the first call bill data of reading to store in buffer zone to be sent to CGF side.
In the present embodiment, so-called the first use state of reading buffer zone meets the second pre-conditioned referring to: first reads buffer zone has write completely, or, the second duration thresholding of arrival systemic presupposition.
For example: still consult shown in Fig. 5, in the present embodiment, suppose that CDF is provided with thread C(and is called again file and reads thread), and thread D(is called again ticket and reads thread), concrete:
Thread C: for selecting an idle buffer zone of reading, as shown in Figure 5, can select to read buffer zone 1, also can select to read buffer zone 2, what suppose to choose is to read buffer zone 1, thread C reads out call bill data from storage area, and write and study in buffer zone 1, when reading buffer zone 1 when writing full or the second duration thresholding and arriving, thread C switches to and reads buffer zone 2, continuation reads out call bill data from storage area, and writes and study in buffer zone 2, reads buffer zone 1 before then notifying thread B process to switch.
Thread D: accept thread C and control, for mailing to CGF side by writing the call bill data of reading buffer zone 1 record full or that the second duration thresholding arrives.
Certainly, when the call bill data in reading buffer zone 2 is write completely or again arrives the second duration thresholding, thread C also can again switch to and read buffer zone 1, and notify thread D that the call bill data of reading in buffer zone 2 is mail to CDF side, idiographic flow, to similar for the operation of reading buffer zone 1, does not repeat them here.
Further, consult shown in Fig. 8, optionally, in order to guarantee the fluency of overall flow, as long as thread C is set to be read call bill data and writes full one and read the required duration in buffer zone (read buffer zone 1 or read buffer zone 2), be not more than thread D a call bill data of reading in buffer zone (read buffer zone 1 or read buffer zone 2) is read to empty duration, or/and, thread C also can be set to be read call bill data and writes full one and read the required duration in buffer zone (read buffer zone 1 or read buffer zone 2), be not more than the second duration thresholding of setting, wherein, this the second duration thresholding reads for characterizing thread C the time interval (above mentioning) that switch buffer zone.Like this, can make thread D move continuously, and need not wait for that thread C execute file read operation is complete, thus the fluency of operation further guaranteed, and further eliminated the system bottleneck causing slowly due to read operation when call bill data reads to buffer zone.
Certainly, above-described embodiment only be take and is existed two to read buffer zone and be introduced as example, in practical application, if exist three and above reading buffer zone, can adopt equally thread C and thread C to read to switch between buffer zone at each, at this, also repeats no more.
