Description
Technical Field
The invention relates to a data communication network charging accuracy detection method capable of detecting the charging accuracy of a data communication network, and belongs to the technical field of communication metering.
Background
In recent years, due to economic growth and social progress, data communication services have been rapidly developed in China. With the rapid popularization of the internet and the continuous emergence of a large number of data services and video services, the original access mode and access network cannot meet the requirements of users. On this background, since 2001, broadband internet access technology represented by ADSL began to be rapidly developed and widely used nationwide. Along with the rapid increase of the user scale, the charge dispute between the internet users and the telecom operators is also increasing. The operating enterprises providing internet service are under increasing doubt in the aspects of reasonability of charging rules, accuracy of charging duration (or charging flow) and the like. Therefore, an effective technical means for detecting and verifying the reasonability of the charging rule of the data communication network access system and the accuracy of the charging duration and the flow is urgently needed by both the consumer and the operator.
Currently, for common users of data communication networks, most telecommunication operation enterprises across the country adopt a mode of charging according to the use duration, and a small part adopts a mode of charging according to communication flow. No matter what charging mode is adopted by the data communication network, no scientific and effective method exists for detecting the charging of the data communication network at home and abroad.
For example, in an ADSL access system that employs long-term charging, an operating enterprise (or user) simply initiates several ADSL calls, records the time of surfing the internet, and then manually detects the charging accuracy through the query function of the ADSL charging system. This method has a number of disadvantages. First, it is not systematic. Because there are only a few ADSL calls, the types and the number of the terminals initiating the calls cannot be regularly divided, and the duration of the calls has a certain contingency, the method cannot be guaranteed in terms of the number of samples or the quality of the samples. Secondly, the method is not scientific enough. Because the types of terminals initiating the ADSL call are various, and the rules and the method for counting the internet surfing time are also five-door, the accuracy of the self-counted charging time is very poor, and certainly, the charging accuracy of an ADSL access system cannot be verified. In addition, because the common ADSL terminal adopted by the method is not specially designed, the charging rules and the charging accuracy of abnormal conditions such as abnormal disconnection, internet surfing across the charging period and the like of the ADSL user are difficult to verify and detect. For an ADSL access system adopting flow charging, no method and device for detecting and verifying charging rules and accuracy exists at present.
Therefore, there is a small distance between the current state of the art in the field of data communication network billing detection and the actual needs of the vast consumer.

In addition, the original billing information generation module 66 is connected to a billing file import module 67 generated by the ADSL system, and the billing file import module 67 generated by the ADSL system is connected to a billing rule analysis and verification module 69 and a billing error rate analysis module 610, respectively.
The following describes a data communication network charging detection method provided by the present invention based on the data communication network charging detection device proposed by the applicant, with reference to the accompanying drawings.
As shown in fig. 5, the data communication network charging detection device proposed by the applicant is accessed into an ADSL access system, and the signaling and data information generated in the process of connecting the device with the ADSL network are collected, recorded and analyzed, and the charging information is formed by an original charging information generation module 66. The charging information is analyzed and compared with the original charging information provided by the operator, so that the items of charging rules, charging error rate, rate and the like of the ADSL access system can be detected and verified.
The specific test content and test steps are as follows:
1. detection and verification of charging rules for ADSL access system to determine user access network and exit network
ADSL access systems are primarily responsible for determining when an ADSL subscriber accesses and exits the network by broadband access server (BNAS) equipment and thus generating the subscriber's original billing information.
Checking the charging rule, firstly, checking the signaling message according to which the ADSL system determines the user's internet access start and internet access end (i.e. charging start and charging end).
As shown in fig. 6, ADSL dial-up subscribers are currently connected to a Broadband Network Access Server (BNAS) using PPPoE protocol. In the communication flow between the ADSL user and the broadband access server (BNAS) device, the Broadband Network Access Server (BNAS) device should determine that the user starts to access the network according to the IPCP configuration-ACK (17) signaling message sent by both parties last. For a decision that a subscriber is logged out of the network, the Broadband Network Access Server (BNAS) device should rely on LCP Terminate-Request (18) messages sent by the subscriber or network. Based on the principle, by setting the ADSL call simulation and flow generation unit 1 of the data communication network charging detection device, the charging rules of the ADSL access system for judging the user to access the network and quit the network can be detected and verified by utilizing the function of simulating and simulating the abnormal ADSL call flow.
Specifically, the ADSL call emulation and traffic generation unit 1 is first controlled by the test system control host 5 to generate a special ADSL call flow. Compared with the normal ADSL call flow (see fig. 6), the flow also goes through the normal discovery phase and LCP negotiation phase, but in the IPCP negotiation phase, the ADSL call emulation and traffic generation unit 1 always does not send ipcpconfiguration-ACK (17) signaling messages. After a while, the ADSL call emulation and traffic generation unit 1 will also send LCP Terminate-Request (18) and PADT (20) messages to emulate the disconnect action of the user. According to the above, in the communication flow between the ADSL user and the Broadband Network Access Server (BNAS) device, the Broadband Network Access Server (BNAS) device should determine that the user starts to access the network according to the IPCP configuration-ACK (17) signaling message sent by both sides last. Since the ADSL subscriber always does not send IPCP configuration-ACK (17) signaling messages that mark the start of billing in this particular ADSL call flow, the ADSL access system should not bill for this ADSL call. By analogy, the ADSL call simulation and flow generation unit 1 is controlled by the test system control host 5, and other special ADSL call flows can be generated to test the charging rules of the ADSL access system. Finally, analyzing and comparing the original charging information provided by the operator, the operator can know whether the rules of the ADSL for accessing the network and quitting the network are the same as the rules.
2. The charging rule of ADSL access system for processing ADSL user abnormal disconnection condition is detected and verified.
When the ADSL user is on the internet, an abnormal disconnection happens occasionally, and at this time, the ADSL access network does not immediately know that the user is disconnected. How the ADSL access system should handle and how long it should monitor this and stop charging is not specified in the relevant standards at home and abroad. The invention can detect and verify the charging rule of the ADSL access system for processing the abnormal disconnection condition of the user by simulating the abnormal disconnection of the user and monitoring the signaling, and the specific test steps are as follows:
firstly, the ADSL call simulation and flow generation unit 1 is controlled by the test system control host 5 to initiate a normal ADSL call flow.
In the process of initiating an ADSL call, the PPPoE protocol signaling flow acquisition module 22 of the ADSL call signaling and data traffic acquisition and upload unit 2 acquires the last IPCP configuration-ACK (17) message sent by both parties through the IP network interface module 21, and then sends the message to the PPPoE protocol signaling flow recording and upload module 24, and the PPPoE protocol signaling flow recording and upload module 24 notifies the test system control host 5, so the PPPoE signaling flow analysis and statistics module 64 of the system test module 6 starts to notify the test control main module 61 that the IPCP configuration-ACK (17) signaling is received, and the user has access to the network and can start charging.
After the ADSL call simulation and flow generation unit 1 simulates the ADSL user to surf the internet for a period of time (the time can be flexibly adjusted), the test system control host 5 controls the ADSL call simulation and flow generation unit 1 to immediately block the IP port connected with the ADSL access network, thereby simulating the abnormal disconnection of the ADSL user, and simultaneously informing the test control main module 61 that the user quits the network and stops charging. At this point, the original billing information generation module 66 may generate the actual billing duration of the ADSL call flow that simulates the abnormal disconnection.
In order to improve the accuracy and stability of the test, the above test steps can be repeated for a plurality of times.
Finally, the charging information counted by the original charging information generation module 66 is analyzed and compared with the original charging information provided by the operator, so as to calculate and judge the charging rule of the ADSL access system for processing the abnormal disconnection condition of the ADSL user.
3. The charging rules of how the ADSL access system calculates and summarizes the total duration of the ADSL user accessing the Internet in a single charging period are detected and verified.
At present, the original charging information of users collected by the charging points of the ADSL access system in the whole country is in units of seconds. When charging the network fee of the last charging period for the ADSL user, the total time length of the network is in minutes. At this time, the charging statistical rules of the total online duration of the operation enterprises in a single charging period of the user are different. Some are to accumulate the time length of the user on the internet once in the charging period by taking seconds as a unit, then convert the sum into the time length by taking minutes as a unit, and process the time length less than one minute according to an upward carry method. Some of the time length of the user on the internet once in the charging period is firstly converted into the time length taking minutes as a unit, the time length less than one minute is processed according to an upward carry method, and finally the processed results are accumulated. The invention can detect and verify the charging rule. The specific test steps are as follows:
in the same charging period, the test system control host 5 controls the ADSL call simulation and flow generation unit 1 to initiate multiple paths of normal ADSL call flows.
In the process of initiating an ADSL call, the PPPoE protocol signaling flow acquisition module 22 of the ADSL call signaling and data traffic acquisition and upload unit 2 acquires the last IPCP configuration-ACK (17) message sent by both parties through the IP network interface module 21, and then sends the message to the PPPoE protocol signaling flow recording and upload module 24, and the PPPoE protocol signaling flow recording and upload module 24 notifies the test system control host 5, and the PPPoE signaling flow analysis and statistics module 64 in the system test module 6 thus starts to notify the test control main module 61 that the IPCP configuration-ACK (17) signaling is received, so that the user has access to the network and can start charging.
After the simulation user accesses the network for a period of time (and before the charging period is finished), the test system control host 5 controls the ADSL call simulation and flow generation unit 1 to initiate a normal ADSL disconnection process. When the PPPoE signaling flow analyzing and counting module 64 receives an LCP Terminate-Request (18) message sent from the user side of the IP network interface module 21, it notifies the test control main module 61 that the user has quit the network and stops charging. At this point, the original billing information generation module 66 may generate billing information for these ADSL call flows.
In order to improve the accuracy and stability of the test, the test steps are repeated for a plurality of times.
Finally, two different statistical rules of accumulating the time length of the user on the internet once in the charging period in seconds and converting the time length of the user on the internet once into the time length in minutes and then accumulating are adopted respectively, and the charging information generated by the original charging information generating module 66 is accumulated and counted to obtain the actual total time length of the charging period counted by the data communication network charging accuracy detecting device. The time length is analyzed and compared with the accumulated user internet surfing time length in the charging period provided by an operator, so that the charging rule of how to calculate and sum the total user internet surfing time length of the ADSL user in a single charging period by the ADSL access system can be detected and verified.
4. The charging rules of how the ADSL access system handles ADSL internet calls that span two charging periods are detected and verified.
In some cases, an ADSL call will span two billing periods specified by the operator. Then, is the charge incurred by the ADSL call listed in the previous billing period, the next billing period, or counted separately in both billing periods? The invention can detect and verify the charging rule under the condition by simulating the user call and monitoring the signaling. The specific test steps are as follows:
when the charging period is about to end, the testing system control host 5 controls the ADSL call simulation and flow generation unit 1 to initiate multiple paths of normal ADSL call flows.
In the process of initiating an ADSL call, the PPPoE protocol signaling flow acquisition module 22 of the ADSL call signaling and data traffic acquisition and upload unit 2 acquires the last IPCP configuration-ACK (17) message sent by both parties through the IP network interface module 21, and then sends the message to the PPPoE protocol signaling flow recording and upload module 24, and the PPPoE protocol signaling flow recording and upload module 24 notifies the test system control host 5, so the PPPoE signaling flow analysis and statistics module 64 of the system test module 6 starts to notify the test control main module 61 that the IPCP configuration-ACK (17) signaling is received, and the user has access to the network and can start charging.
After the charging period has ended and the next charging period begins for a period of time, the testing system control host 5 controls the ADSL call simulation and flow generation unit 1 to initiate a normal ADSL disconnect flow. When the PPPoE signaling flow analyzing and counting module 64 receives an LCP Terminate-Request (18) message sent from the user side of the IP network interface module 21, it notifies the test control main module 61 that the user has quit the network and stops charging. At this point, the original billing information generation module 66 may generate billing information for ADSL web call flow that spans two billing periods.
The charging information counted by the original charging information generation module 66 is analyzed and compared with the original charging information provided by the operator, so that the charging rule of how the ADSL access system processes the ADSL internet access call spanning two charging periods can be calculated and judged.
5. The tariff of the ADSL access system is detected and verified.
