Embodiment 1

[0030] figure 1 It is a flowchart of a WAP network fault location method according to an embodiment of the present invention. Such as figure 1 As shown, this embodiment includes:

[0031] Step S102: According to the error code of the drive test tool, map the fault cause corresponding to the error code;

[0032] Step S104: Set a packet capture point at each node of the WAP network, and obtain a test data packet corresponding to the preset data packet at the packet capture point for the preset data packet; according to the preset data packet and the test data obtained at the packet capture point package to locate WAP network faults.

[0033] In this embodiment, firstly, according to the daily test results and the error codes of the drive test tool, the cause of the possible failure is obtained; then, according to the above reasons, the point where the failure occurs is specifically located at each packet capture point. This embodiment overcomes the defect that the error info...

Embodiment 2

[0035] This embodiment will mainly describe step S102 of the embodiment. During the CQT and DT tests using the CDS drive test tool, sometimes the test fails. You can view some specific error codes through the CDS tool. These error codes are generally initiated by the mobile phone or WAP gateway (abort ) request, the specific reasons for abort (abandon) are generally divided into two categories: WSP and WTP.

[0036] Table 1 shows the reasons and codes corresponding to the WSP abandonment reasons. As shown in Table 1, the reason codes include 0xE0~0xEF, and the most common WSP abandonment reason codes in the CQT test are 0xE1 and 0xE8.

[0037] Table 1 shows the reasons and representation codes corresponding to the WSP abandonment reasons

[0038]

[0039]

[0040] Table 2 shows the reasons and representation codes corresponding to the WTP abandonment reasons. As shown in Table 1, the reason codes include 0x00~0x0A, and the most common WTP abandonment reason codes in the...

Embodiment 4

[0075] This embodiment will describe step S104 in Embodiment 1 in detail. In this embodiment, the technical tools used: CDS4.0 or 5.0, network protocol analyzer Wireshark, packet capture tool Wireshark, Compass GPRS, applied network environment: EGPRS or GPRS (wireless)+GPRS core network+WAP gateway.

[0076] The above errors may be encountered when using the CDS tool for CQT testing. Since there are various reasons for the errors, to analyze the final cause, you must go through the entire WAP process (including the CDS side, the Gb port of the BSC, and the Gi of the GGSN). port, WAP gateway) message packets. If there are only CDS message packets, the problem can only be judged initially, and it is impossible to locate the specific network element that is faulty. Therefore, we suggest that if you encounter a problem that cannot be diagnosed during the test, it is recommended to coordinate the wireless side, core network, and WAP. Simultaneous packet capture analysis and compa...

Abstract

The invention discloses a method and a system for positioning a wireless application protocol (WAP) network failure. The method comprises the following steps of: mapping a failure cause corresponding to an error code according to the error code of a drive testing device; setting a packet-capturing point at each node of a WAP network and acquiring a test data packet corresponding to a preset data packet at the packet-capturing point according to the preset data packet; and positioning the WAP network failure according to the preset data packet and the test data packet acquired at the packet-capturing point. According to each embodiment of the invention, a relationship between a nonstandard error code and the failure is mapped and multi-point packet capturing is combined, so that the failure can be positioned accurately and the network maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of business support in the communication industry, in particular to a method and system for network fault location. Background technique [0002] At present, the business support departments in the communication industry are equipped with CDS (Cellular Drive test System) drive testers, and there are a large number of CQT (Call Quality Test) and DT (Drive Test) tests every day, and in GPRS, WAP The cutover of WAP systems such as MMS and MMS, and software version upgrades require business testing and billing verification. [0003] During the CQT test or DT test using the CDS drive test tool, sometimes the test fails. You can view some specific error codes through the CDS tool, but some codes are not standard error codes, or the CDS manufacturer The code or basis defined by oneself is wrongly defined. Error codes such as 0xe1, 0xe8, 0xff, 0x48, wap Gatewapconnect fail, wsp get fail encountered by the CDS test...
