Description

A testing method and device for forwarding rules

technical field

The invention relates to the communication field, in particular to a method and device for testing a forward pass rule.

Background technique

WAPGW (Wireless Application Protocol Gateway, WAP gateway) forwarding rules define the correspondence between websites and forwarding information. Due to business needs, WAPGW needs to forward the user's mobile phone number, IP address and other information to some trusted websites. This information involves user privacy, so forwarding information control is very important. For untrusted websites, user information cannot be forwarded. The website can only forward the necessary user information. The WAP gateway URL forwarding rules define which websites are forwarded and what information is forwarded.

The user information that can be forwarded includes but is not limited to MSISDN (Mobile Station International ISDN Number, mobile station international ISDN number), MS IP, NAS IP, SGSN IP, APN (AccessPoint Name, access point name), etc. For the convenience of forwarding control, these information are represented by different forwarding codes. The definition and expression of the forwarding codes are as follows, as shown in Table 1:

forward information prepass code MSISDN 1 MS IP Address 5 Bearer Type (GPRS, CSD, SMS, etc.) 6 NAS IP 7 APN 8

Table I

WAPGW maintains a table of correspondence between URLs and pre-pass codes, examples are as follows, as shown in Table 2:

URL Pre-pass code information http://www.AAA.com 1,8 http://www.BBB.com 1, 5, 6 http://www.CCC.cn 6, 7, 8

Table II

Compared with the definition of the forwarding code, the content of this table indicates that http://www.AAA.com needs to forward MSISDN and APN, and http://www.BBB.com needs to forward MSISDN, MS IP and BearerType.

Due to frequent changes in Internet services, operators need to frequently modify URL forwarding rules on WAPGW, and each modification often involves a large number of URLs, which brings great challenges to the verification work after modification. The method in the prior art is to capture the network message sent by the WAPGW to the service provider SP for confirmation. However, the inventor found that if there are many URLs set, this confirmation method will consume a large amount of work. According to the survey, each provincial office of a certain operator modifies the pre-transmission rules twice a week on average, and each modified test costs an average of one person. day's workload. Manual verification is very inefficient, time-consuming and labor-intensive, and requires manual packet capture and analysis. If there are many URLs set, the workload of verification will be heavy.

S101. Construct a forwarding rule query request and send it to the forwarding rule storage device;

Since the acquisition of existing pre-transmission rules is achieved by grabbing network messages, the efficiency is low and the difficulty is high. The embodiment of the present invention actively constructs a pre-transmission rule query request and sends it to the storage device storing the pre-transmission rules to be tested. To realize the acquisition of the fronthaul rules applied in the actual network.

S102. Receive the forwarding rule returned by the forwarding rule storage device according to the preset feedback mode;

As mentioned above, since the test device and the fronthaul rule storage device agree on a feedback method, the fronthaul rule storage device returns the stored fronthaul rule data according to the preset feedback method after receiving the query request;

Since the fronthaul rules may involve the user's privacy or information that is unwilling to be disclosed, in this step, after the fronthaul rule storage device receives the query request, it can further authenticate the query request to ensure the legitimacy of the query party. After passing the authentication, query and feedback the forwarding rules.

Efficient acquisition and testing reduces the workload of acquiring and testing fronthaul rules and improves the efficiency of fronthaul rule testing.

Embodiment two

Embodiment 2 of the present invention takes the test device requesting the pre-transmission rules from the WAP gateway as an example to illustrate the method of Embodiment 1 of the present invention; the method in this embodiment is: the test device and the WAPGW preset pre-transmission rule query request and response mode, when the test starts , the test device sends a special HTTP request to WAPGW, and the URL of the HTTP request is the URL to be queried. After WAPGW judges that this is a pre-pass rule test request according to the pre-agreed feedback method, it queries the URL in the cache and the pre-pass code comparison table. Respond to the test device with the queried forward code in the form of HTTP header. After the test device gets the response, it analyzes the pre-transmission code according to the pre-agreed feedback method, compares it with the rules set by the customer, and finds out whether the pre-transmission field is correct.

Referring to accompanying drawing 2, the specific process is described as follows:

S201. The test device constructs a test request;

Test requests are HTTP requests. For example, the test device needs to query the forwarding rules corresponding to the URL: http://www.111.com, so the x-aaa-TestType field is included in the test request to identify the request as a test request, and its value is set to 1, means to test the fronthaul rule; of course, other flags can also be defined and the values in the flags can be set to other values, which are not limited in this embodiment.

S202. The test device sends the HTTP request to the WAPGW;

The request includes a query URL and a test identifier.

S203. After receiving the request, the WAPGW detects that the request message contains the "x-aaa-TestType: 1" field, and judges that this is a fronthaul rule test request according to the pre-agreement;

S204. Authenticate the inquiring party;

In order to protect user privacy and prevent ordinary users from obtaining URL forwarding rule information, WAPGW can authenticate the test device, for example, authenticate the IP address of the test device, and only allow the set IP address to initiate the forwarding rule test. For other IP Address requests are processed or not processed as normal business requests.

S205. WAPGW queries the forwarding rules of the request URL;

Query the forwarding rules corresponding to http://www.111.com cached on WAPGW.

S206, WAPGW constructs a query result message;

WAPGW constructs a query result message and responds, and adds prequel field information to the response query result message. Specifically, WAPGW identifies the queried forwarding rules in the forwarding rule response field x-aaa-FwdHeaders, such as: aaa-FwdHeaders: 1, 8, where 1, 8 are the forwarding codes, referring to the previous example in the background technology, this The response indicates that for the URL http://www.111.com, WAPGW will forward the two fields of MSISDN and APN. Certainly, the fronthaul rule response may also be other character strings, which is not limited in this embodiment.

S207, WAPGW sends a query result message to the test device;

S208-210. The test device parses the prequel field, judges whether it matches the prequel field set by the user, and displays the result;

After receiving the response, the test device parses the x-aaa-FwdHeaders field, and finds that the prequel fields of the current URL are 1 and 8, judges whether it is consistent with the rules imported by the user, and presents the result to the user.

In the method of the embodiment of the present invention, the test device and the WAP gateway agree in advance that by adding a special field in the HTTP request to indicate the forwarding rule test, the WAPGW directly queries the URL forwarding rule without performing business processing after receiving the forwarding rule query request, and passes the corresponding The field notification test device realizes the efficient acquisition and testing of the fronthaul rules, reduces the workload of the fronthaul rule acquisition and testing, and improves the efficiency of the fronthaul rule testing. Since this embodiment is implemented on the basis of the HTTP protocol, there is no need to make great changes to the existing process, and the implementation is simple and convenient. In addition, the WAPGW authenticates the fronthaul rule tester, which further ensures the security of the fronthaul rule test and user privacy.

Embodiment Three

The embodiment of the present invention utilizes the network management module, also known as the OAM (operation administration and maintenance, operation, maintenance and management) module, to realize the acquisition and testing of the forward transmission rules.

Since all business module nodes need to maintain connection with OAM, each business module node will be assigned a unique node ID (NodeID), so that the forward transmission rule feedback method can be agreed between OAM and a certain business module node (NodeN), For example, URL forwarding rule query messages and query response messages can be defined. Examples of message definitions are as follows:

Query request message format, as shown in Table 3:

field name Field Type value illustrate MsgType int 6 (indicates that the URL forwards the query request message) MsgID int Message ID, incremented NodeID char The business process ID to be queried end with /0 URL char The URL to be queried end with /0

Table three

Query response message format, as shown in Table 4:

field name Field Type value illustrate MsgType int 7 (indicates that the URL forwards the query response message) MsgID int Message ID Same as the MsgID in the query request message FwdHeaders char Pre-pass code, such as "1, 6, 8" end with /0

Table four

During specific implementation, a UI (User Interface, user interface) module can be added to be responsible for user operations and result display. The UI module initiates a query message to OAM, and OAM forwards the query message to the correct The message queried by the module node is returned to the UI module. After receiving the response, the UI module parses out the query result, judges whether it is consistent with the forwarding rules imported by the user, and presents the result to the user.

Specifically, with reference to accompanying drawing 3, the specific description of the embodiment of the present invention is as follows:

S301. The UI constructs a query request message as shown in Table 3;

S302. The UI sends a query request to the OAM;

The query request sent to the OAM through the UI includes the ID of the NodeN to be queried, and the message includes a MsgType (message type), indicating that it is a URL forwarding rule query message.

S303. The OAM queries the IP address corresponding to the NodeN;

Since the OAM stores the correspondence between the ID of the NodeN and the IP address, the IP address corresponding to the NodeN can be queried.

S304. The OAM forwards the query request to NodeN;

S305, NodeN performs URL forwarding rule query, and constructs a response message;

The constructed response message may be as shown in Table 4. The MsgType identifies that the response message is a URL forwarding rule query response; in the FwdHeaders field of the message, forwarding rule information is identified, such as forwarding codes 1, 6, and 8.

S306. NodeN sends a response message to OAM;

S307. The OAM forwards the query response message to the UI;

S308. The UI parses the prequel field information;

S309. The UI judges whether the parsed forward code is consistent with the one set by the user;

S310. The UI displays the test result.

Before the step S305, after receiving the query request, the NodeN may further verify the legitimacy of the request sender.

In the embodiment of the present invention, through the pre-defined forwarding rule query message and query response message between OAM and NodeN, the OAM sends the forwarding rule query request to the corresponding queried node, and receives the response containing the forwarding rule returned by the corresponding node , which realizes the efficient acquisition and testing of fronthaul rules, and reduces the workload of acquisition and testing of fronthaul rules.
