At present, wireless data service receives the very big concern of operator as the high value-added business.But current charge mode to wireless data service is comparatively simple, or calculates according to data traffic, or according to the duration calculation of transfer of data, these charge mode all can't adapt to the develop rapidly of wireless data service.For the operation scheme of integration of wireless data service, seek bigger professional profit, operator need develop more rational charge mode.In this, content charging (CBB) can be satisfied the charging demand of operator better.The implication of CBB is: charge system is according to the different expenses standard of the professional execution of the different pieces of information that the user carried out.The committed step that realizes CBB is: system need judge which kind of type of service is the user data package of transmission over networks belong to.This means, need the network equipment of energy judgment data type of service on the network of transmitting user data bag, tell the type of service of user data package by this network equipment by the up-downgoing packet of resolving the user.The content that the parsing of user data package is related to layer three, layer four and layer seven this three protocol layers in network service seven layer protocols.Wherein, layer three is network layers, and what finish is IP address resolution to user data package; Layer four is transport layers, and what finish is that the port of user data package is resolved; Layer seven is application layers, and what finish is the parsing of the URL(uniform resource locator) (URL) to user data package.Wherein, URL is made up of character.According to the agreement regulation, URL has specific form, and different URL format field separates with separator and represents different contents, and each format field with URL among the application is called different URL subitems.Such as: in " http://www.sina.com.cn ", " http " is the schema subitem of this URL, and " www.sina.com.cn " is the host subitem of this URL.Because agreement has been given different content implications with the form of form to URL, so URL can not be regarded as simple character string.
For realizing seven parsing of above-mentioned layer, promptly user data package URL is resolved, need set in advance the url filtering condition, the corresponding a kind of data service type of each url filtering condition being used to resolve on the network equipment of URL; When user data package passed to this network equipment, the network equipment was judged the type of service of this user data package according to the match condition of user data package URL and url filtering condition.Here, described user data package URL is meant the entrained URL of user data package that the network equipment obtains.
Above-mentionedly being used to judge that the network equipment whether user data package URL and url filtering condition mate can be GGSN (GGSN), also can be WAP gateway, or any one network equipment in the network data transmission process.
In the prior art, judge that the method whether user data package URL and url filtering condition mate is as follows: suppose that the url filtering condition that the network equipment sets in advance is respectively A1 and A2; After this network equipment receives user data package, this user data package URL and A1, A2 are carried out character string respectively relatively, if user data package URL and A1 are equal fully, then this network equipment is judged this user data package URL and A1 coupling, and promptly this user data package belongs to A1 corresponding service type; If user data package URL and A2 equate that then this network equipment is judged this user data package URL and A2 coupling, promptly this user data package belongs to A2 corresponding service type; At last, this network equipment is with matching result, and promptly the type of service of user data package reports charge system, and charge system is provided with the Freight Basis to different service types, finally finishes content-based charging.
But, the URL matching process of available technology adopting is processed into simple character string with URL, adopt the method that character string is mated fully that URL is resolved, the content implication that this URL matching process does not well utilize the URL item to be endowed is so can't satisfy the flexible charging demand of CBB.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of matching process of URL(uniform resource locator), the charging demand content-based according to network is provided with matching condition flexibly, make matching result more relevant with the URL content, improve the fineness of content charging, and the coupling protocol compliant that this method is finished is stipulated.

Description of drawings
Fig. 1 is the URL coupling flow chart of a preferred embodiment of the present invention.
Embodiment
Core concept of the present invention is: the network equipment is provided with the url filtering condition and obtains user data package URL; Then, the network equipment splits set url filtering condition and the user data package URL that is obtained respectively according to the agreement regulation, obtains the subitem of two groups of URL respectively; At last, the network equipment compares the same type subitem of url filtering condition and these two groups of URL of user data package URL, draws matching result.
Here, described user data package URL is meant the entrained URL of user data package that is sent to the network equipment.The same type subitem of described two groups of URL is meant the URL subitem that belongs to identical URL format field among two groups of URL.
For making purpose of the present invention, technical scheme and advantage clearer, by the following examples, the present invention is described in more detail.
Among the present invention, in order to realize that data to Network Transmission are based on content charging, can the URL matching module be set being used to judge on the network equipment whether user data package URL and url filtering condition mate, thereby the matching result that this network equipment is drawn compared with prior art embodies the characteristics of content-based coupling better, finally makes charge system can utilize the content-based charging of the better realization of this matching result.
The network equipment of the above-mentioned URL of setting matching module can be GGSN (GGSN), perhaps the network equipment in the network data transmission process such as WAP gateway.
The course of work of the URL matching module that is provided with on the network equipment as shown in Figure 1, is as follows:
Step 101:URL matching module is provided with the url filtering condition.
Because the network data content is various, the URL matching module can be provided with the url filtering condition as required flexibly.Such as: the URL matching module is provided with " http://www.sina.com.cn ", " http://www.google.com ", " http://www.263.net ", " http://www.yahoo.com ", " http://www.baidu.com ", " http://www.tom.com " are the url filtering condition.That is to say that the URL matching module can be provided with different filtercondition arbitrarily as required, and the type of service of user data package is judged respectively, charge according to judged result again according to different url filtering conditions.
Step 102: when a certain user data package on the network transferred to the network equipment that comprises the URL matching module, the URL matching module obtained this user data package URL.
Step 103:URL matching module splits url filtering condition and user data package URL according to standard protocol specifies, obtains the subitem of two groups of URL respectively.
Be that example is elaborated to splitting URL according to agreement with the RFC1738 agreement below.The RFC1738 agreement to the definition of URL form is＜schema 〉:＜schema-specific-part, wherein＜schema-specific-part form can be further defined as //＜user:＜password〉@＜host:＜port 〉/＜url-path.Complete for having＜schema 〉: //＜user 〉:＜password〉@＜host 〉:＜port 〉/＜url-path〉URL of form, can split out schema subitem, user subitem, password subitem, host subitem, port subitem, and the path subitem.The RFC1738 agreement comprises: http protocol type, File Transfer Protocol type etc.The agreement regulation, the URL of http protocol type does not have user subitem and password subitem.
Further the URL " http://www.263.net/path/page.html " with the http protocol type is an example, and the concrete steps that subitem splits are described.This URL can be the url filtering condition, also can be user data package URL.
At first, search separator among the URL ": // ", ": // " character string before is exactly the schema subitem of URL.The schema subitem is " http " in this example.If there is not separator ": // ", then schema subitem acquiescence is " http ".
Secondly, search the content between separator ": // " and the separator "/", obtain character string " www.263.net ".Content between separator ": // " and the separator "/" comprises host subitem and port subitem, the URL matching module is searched separator ": " between separator ": // " and separator "/", separator ": " content before is the host subitem, and separator ": " content afterwards is the port subitem.Do not have separator ": " in this example, so this URL has only host subitem " www.263.net ", the port subitem adopts the default port of http agreement in this example.
At last, search separator "/" content afterwards, this partial content is exactly the path subitem.The path subitem is in this example: " path/page.html ".
Through the process that above-mentioned subitem splits, http://www.263.net/path/page.html splits into three subitems, is respectively: schema subitem " http ", host subitem " www.263.net ", and path subitem " path/page.html ".
For other protocol type, such as File Transfer Protocol, the URL matching module also is to carry out subitem according to the related protocol regulation to split, and the URL method for splitting of method for splitting and http protocol is similar, does not give unnecessary details herein.
In actual applications, because the URL matching module need carry out matching operation to the subitem of url filtering condition and user data package URL fractionation acquisition, so the fractionation to URL will stipulate that not only the subitem that url filtering condition and user data package URL fractionation is obtained can be corresponding one by one according to agreement.Suppose that the url filtering condition is " http://www.huawei.com.cn/news/index.shtml ", user data package URL is " http://www.huawei.com.cn/about/index.shtml ".The url filtering condition splits and obtains schema subitem " http ", host subitem " www.huawei.com.cn ", and path subitem " news/index.shtml ", then user data package URL also splits and obtains schema subitem " http ", host subitem " www.huawei.com.cn ", and path subitem " about/index.shtml ", that is: the subitem of two URL fractionation acquisitions is corresponding one by one.If user data package URL is " www.huawei.com.cn/about/index.shtml ", then split to obtain host subitem " www.huawei.com.cn " and path subitem " about/index.shtml ", and schema subitem use as default " http ".
When subitem split, the URL matching module can be provided with the significance level of dissimilar URL subitems, and the URL subitem that significance level is lower can not carry out subitem and split.
Fractionation for the url filtering condition, the URL matching module can just carry out subitem to corresponding URL and split when the url filtering condition is set, also can when mate user data package URL with the url filtering condition, needs just the url filtering condition be carried out subitem and split.
Step 104:URL matching module compares the same type subitem that url filtering condition and user data package URL split two groups of URL that obtained, and draws matching result.
The same type subitem of described two groups of URL is meant the URL subitem that belongs to identical URL format field among two groups of URL.
The URL matching module can be provided with subitem strategy relatively, and the strategy of subitem comparison includes but not limited to following mode:
At first, as described in step 103, the URL matching module can be provided with significance level for the URL subitem.The URL matching module can be provided with the significance level of URL subitem before subitem splits, can not carry out subitem for the low URL subitem type of significance level and split; The URL matching module also can be provided with the significance level of URL subitem after subitem splits.The URL matching module can also be according to the significance level decision subitem sequencing relatively of URL subitem.
Secondly, when certain URL subitem was compared, the URL matching module can be provided with the comparison ambiguity.Whether relatively ambiguity includes but not limited to following several mode: case sensitive when (1) subitem compares; (2) whether support asterisk wildcard during the subitem comparison; (3) whether support inclusion relation during the subitem comparison; (4) whether support domain name and IP address corresponding relation during the subitem comparison.
How the URL subitem to be compared below in conjunction with used example explanation URL matching module in the step 103 by significance level is set.
In this example, the url filtering condition is " http://www.huawei.com.cn/news/index.shtml ", and user data package URL is " http://www.huawei.com.cn/about/index.shtml ".
The mode of URL subitem significance level is set after subitem splits for the URL matching module, the subitem split result that obtains according to step 103 in this example is as follows: the url filtering condition splits and obtains schema subitem " http ", host subitem " www.huawei.com.cn ", and path subitem " news/index.shtml "; User data package URL splits and obtains schema subitem " http ", host subitem " www.huawei.com.cn ", and path subitem " about/index.shtml ".Then, the significance level that the URL matching module is provided with the schema subitem is the highest, the significance level of host subitem secondly, the significance level of path subitem is minimum.According to the significance level that is provided with, the URL matching module compares the schema subitem earlier, compares the host subitem then, compares the path subitem at last.
For the URL matching module mode of URL subitem significance level is set before subitem splits, the subitem that significance level is low can not carry out subitem and split in step 103.In this example, the significance level that the URL matching module is provided with the schema subitem is the highest, the significance level of host subitem secondly, the significance level of path subitem is minimum.The URL matching module only compares the schema subitem of two URL, draws matching result.The schema subitem of two URL is identical in this example, so the URL matching module judges that user data package URL belongs to this url filtering condition corresponding service type in this example, charge system is carried out disbursement and sattlement according to the expenses standard of this url filtering condition to this user data package URL.At this moment, the URL matching module can not split the host subitem and the path subitem of two URL correspondences.
When certain URL subitem was compared, the URL matching module drew matching result according to set comparison ambiguity.
Case sensitive or case-insensitive when (1) the URL matching module can be provided with the subitem comparison.Such as: the path subitem of two URL is respectively " path/page.html " and " Path/page.html ", and for the case sensitive situation, the URL matching module judges that these two URL subitems do not match; For the situation of case-insensitive, the URL matching module is then judged this two URL subitem couplings.
Support asterisk wildcard when (2) the URL matching module can be provided with the subitem comparison or do not support asterisk wildcard.Asterisk wildcard provides the easy way with a title designated character, the most frequently used asterisk wildcard be " * " and "? "Such as: two URL subitems are respectively: " path/page.html " and " path/*.* ", for the situation of supporting asterisk wildcard, the URL matching module is judged this two URL subitem couplings, and for the situation of not supporting asterisk wildcard, the URL matching module judges that then these two URL subitems do not match.
Support inclusion relation when (3) the URL matching module can be provided with the subitem comparison or do not support inclusion relation.Such as: for the situation of supporting inclusion relation, if certain subitem of user data package URL comprises the corresponding subitem of url filtering condition, the URL matching module is judged this two URL subitem couplings.
Support domain name and IP address corresponding relation when (4) the URL matching module can be provided with the subitem comparison or do not support domain name and IP address corresponding relation.Such as: for the situation of supporting domain name and IP address corresponding relation, suppose that domain name and IP address with corresponding relation are respectively: " www.sina.com.cn " and " 202.11.232.112 ", then the URL matching module is judged this two URL subitem couplings.
Uses that can also superpose of above-mentioned several relatively ambiguity, such as: relatively ambiguity can be case sensitive and support asterisk wildcard, does not perhaps support asterisk wildcard but support inclusion relation etc.
The URL matching module can also adopt different comparison ambiguityes to dissimilar URL subitems, such as: the path subitem is adopted the comparison ambiguity of supporting asterisk wildcard, the schema subitem is adopted the comparison ambiguity of not supporting asterisk wildcard.For another example: to the host subitem, the URL matching module can be provided with and support domain name and IP address corresponding relation when subitem compares.If two host subitems have corresponding relation, the URL matching module is judged this two host subitem couplings.The host subitem of supposing the url filtering condition is " www.sina.com.cn ", the host subitem of user data package URL is " 202.11.232.112 ", if being provided with " www.sina.com.cn " and " 202.11.232.112 ", the URL matching module has corresponding relation, then these two host subitem couplings.
After adopting URL matching process of the present invention to obtain matching result, the URL matching module can be determined the type of service of user data package URL, and the type of service of user data package URL is reported charge system, thereby realizes the flexible charging of CBB.
Method of the present invention can also be applied in the fire compartment wall in the access control technology to the layer 7 agreement.
By the above embodiments as seen, this URL matching process of the present invention carries out the subitem fractionation according to the agreement regulation to user data package URL and url filtering condition, make and split the URL subitem clear in structure that obtains, be convenient in the URL coupling, embody the URL content better, be applicable to content-based charging the in the charge system, and this seed item splits and the method for coupling is simple, is convenient to realize on the network equipment.
