Abstract

The invention discloses a method, a system and equipment for accounting and accessing data, which belong to the field of communications. The accounting method comprises the following steps: receiving an entry adding request; if the adding request is determined as an adding request based on an identification type entry, judging whether an attribute value of the identification type entry appears in an established directory information tree or not; and if not, adding the identification type entry into the directory information tree according to a full entry name of the identification type entry. The accessing method comprises the following steps: receiving an entry accessing request; if the accessing request is confirmed as an accessing request based on the identification type entry, searching index information of the identification type entry according to access route information to confirm full route information of the identification type entry to be accessed; and executing accessing operation based on the identification type entry according to the full route information. The system comprises an access server and an access client. The method, the system and the equipment ensure the uniqueness of the identification attribute value of the identification type entry, solve the accessing problem in an LDAP according to the identification type entry, and simplify the access interaction based on the identification type entry.

Description

The method that a kind of data are opened an account, visited, system and equipment

Technical field

The present invention relates to the communications field, method, system and equipment that particularly a kind of data are opened an account, visited.

Background technology

LDAP (Lightweight Directory Access Protocol, Light Directory Access Protocol) is a kind of directory services access agreement based on model of client.Utilizing the LDAP technology to solve HLR (Home Location Register; Attaching position register)/HSS (Home Subscriber Server; When home subscriber server) using; Its application process is following: at first, the data among HLR or the HSS are put into amalgamation database, obtain the user data that HLR/HSS FE needs by HLR/HSS FE (Front End) through ldap interface visit amalgamation database.LDAP is applied to HLR is that example describes; Referring to Fig. 1, the part directory information tree sketch map that provides HLR to use, this directory information tree (DIT; Directory Information Tree) is a directory tree of forming by clauses and subclauses; So-called clauses and subclauses (Entry) are meant a node of directory information tree, are the base units in the directory information tree, are made up of one or more object class; Use clause name (DN, Distinguished Name) clauses and subclauses of unique identification in a directory information tree; For example; DN to clauses and subclauses among Fig. 1 " MSISDN=1351111111; IMSI (International Mobile Subscriber Identification Number, custom IC)=460031111111, dc=root " is exactly " MSISDN=1351111111; IMSI=460031111111, dc=root "; Use the relative name (RDN, Relative Distinguished Name) of clauses and subclauses to identify same father's bar clauses and subclauses now; For example; To the clauses and subclauses among Fig. 1 " MSISDN=1351111111, IMSI=460031111111, dc=root "; " MSISDN=1351111111 " is the sub-clauses and subclauses of his father's clauses and subclauses " IMSI=460031111111 ", and its RDN i.e. " MSISDN=1351111111 ".

The inventor realizing when of the present invention, finds existingly when utilizing the application that LDAP solves HLR/HSS, has following shortcoming and defect at least:

Existing LDAP technology can't guarantee that the MSISDN value (or IMPI value of IMPI clauses and subclauses) of MSISDN clauses and subclauses does not repeat in its directory information tree; With the MSISDN clauses and subclauses is example: because existing LDAP technology is after receiving the request of opening an account; Be through request analysis that this is opened an account; After obtaining the full DN of the clauses and subclauses that desire increases, whether his father clauses and subclauses IMSI under have identical MSISDN value, if do not have if judging; Then accomplish the corresponding operation that increases by amalgamation database; Before increasing the MSISDN clauses and subclauses in the above-mentioned flow process of opening an account or increasing IMPI, not and the MSISDN clauses and subclauses or the IMPI that have existed under other father's clauses and subclauses IMSI compare, can't guarantee that the MSISDN clauses and subclauses do not repeat in HLR DIT.

And during operations such as existing LDAP technology increases, modification and deletion, at first; HLR/HSS sends the LDAP query requests to amalgamation database, and amalgamation database inquires the full DN of these MSISDN clauses and subclauses or IMPI clauses and subclauses according to the MSISDN or the IMPI that carry in the request, and in inquiry response, returns this full DN; After receiving inquiry response; HLR/HSS is according to this full DN and increase the full DN that the business information formation of carrying in the new service request increases clauses and subclauses newly, and transmission LDAP increases asks to give amalgamation database, and the amalgamation database completion increases accordingly to be operated; This kind mode of operation need be through repeatedly mutual, and handling process is complicated.

Embodiment

For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.

The inventor finds no matter be the MSISDN clauses and subclauses under the HLR when realizing the embodiment of the invention, or the IMPI clauses and subclauses under the HSS, because it has identical characteristics:

1, occurs in the fixed position of directory information tree;

2, has identical Property Name, (being that the RDN Property Name is identical);

3, its property value (MSISDN value or IMPI value) is unique in directory information tree, must not repeat.

Based on These characteristics; The clauses and subclauses unified Definition that the inventor will have These characteristics is sign type clauses and subclauses; Expand at ldap protocol, indicate sign type clauses and subclauses through the form that increases indication, just make behind the server stress model can clear and definite which type clauses and subclauses be sign class clauses and subclauses.

Basis based on definition sign type clauses and subclauses; When LDAP increases sign class clauses and subclauses (new account) newly; Uniqueness inspection that need type of sign clauses and subclauses; When confirming that this sign type clauses and subclauses are unique, just increase operation accordingly, guaranteed the uniqueness of the identity property value of sign type clauses and subclauses under directory information tree; In addition, according to the characteristics of sign type clauses and subclauses, the embodiment of the invention also provides the method that sign type clauses and subclauses are conducted interviews, and to solve the visit interaction times many problem of prior art based on sign type clauses and subclauses, its embodiment is follow-up to be explained.

The described data of the embodiment of the invention are opened an account and are the operation of newly-increased sign type clauses and subclauses, the method for described data access refer to the sign class data of having opened an account increase, operations such as deletion, modification, inquiry.

At first; Introducing the embodiment of the invention is that the property value that is implemented in sign such as MSISDN or IMPI type clauses and subclauses among the LDAP does not repeat; The method that the sign class clauses and subclauses that provided are opened an account, in the present embodiment, sign type clauses and subclauses are that example describes with the MSISDN clauses and subclauses in HLR uses specifically.

Of preamble; The MSISDN clauses and subclauses that HLR uses; Have identical RDN attribute " MSISDN ", and its MSISDN value characteristics that can not repeat each other, describe the MSISDN clauses and subclauses through expansion LDAP technology and be sign type clauses and subclauses; Multiple extended description mode can be arranged, and having provided wherein a kind of describing method below and be the clauses and subclauses that indicate which type through the form that increases designator is sign type clauses and subclauses.

Definition to entry type among the RFC4512 is described through DITContentRuleDescription, and concrete ABNF (Augmented Backus-Naur Form, the Backus normal form (BNF) of expansion) syntactic definition is following:

Wherein, < numericoid>is used for representing the ID of the structure objects class under this entry type; NAME < qdescrs>is used for describing the short name of this entry type; DESC < qdstring>is used for simply describing this entry type; Whether OBSOLETE is used for indicating this entry type definition to activate; AUX < oids>is used for enumerating the ID of all Sec ObjClass that this entry type comprises; MUST < oids>has been used for listing the essential attribute that this entry type comprises; MAY < oids>has been used for listing the optional attribute that this entry type comprises; NOT < oids>has been used for listing the attribute that can not occur in this entry type; < extensions>is used for having described expansion.

In embodiments of the present invention, increase above-mentioned designator, realize description sign type clauses and subclauses through the extended field < extensions>that uses DITContertRuleDescription.

According to the syntactic structure of extensions, the field below the extensions of DITContertRuleDescription partly uses is represented sign type items for information:

Above-mentioned, X-KeyIdentifier is above-mentioned designator, and when X-KeyIdentifier existed, the clauses and subclauses that show the type were sign type clauses and subclauses, and its value is the sign generic attribute title (being the RDN Property Name) of this sign type clauses and subclauses; On the contrary, when X-KeyIdentifier did not exist, the clauses and subclauses that show the type were not sign type clauses and subclauses.Wherein, the sign generic attribute title of different identification class clauses and subclauses (being the RDN Property Name) different (for example, MSISDN and the IMPI under the HSS under the HLR are inequality, so that different sign class clauses and subclauses are distinguished).What provide to the embodiment of the invention is the situation of example with MSISDN, and the MSISDN clauses and subclauses of using this extended method to describe are following:

Wherein, Shown that through X-KeyIdentifier ' MSISDN ' clauses and subclauses of the type belong to sign type clauses and subclauses; And its sign generic attribute title (being the RDN Property Name) is MSISDN, and the sign generic attribute title of the sign class clauses and subclauses of other type (being the RDN Property Name) can not be MSISDN.

Referring to Fig. 2, the method that the embodiment of the invention provides sign type clauses and subclauses to open an account, the client of LDAP is specially service dispense equipment Provision; LDAP Server is specially amalgamation database, and concrete steps are following:

Step 101:Provision sends LDAP to amalgamation database and adds request LDAP Add Request, and request increases new MSISDN clauses and subclauses; Wherein, carry in the request and wait to increase the full DN of MSISDN clauses and subclauses, the property value of these MSISDN clauses and subclauses.

Wherein, this LDAP Add Request request is used to ask to increase new MSISDN clauses and subclauses, i.e. request increases a new MSISND entry attributes value, and for example, it is 1350000002 that request increases new cellphone subscriber's number.

Step 102: after amalgamation database is received LDAP Add Request request; Confirm that the clauses and subclauses that this time increase are sign type clauses and subclauses; MSISDN items for information among the existing directory information tree DIT of inquiry; Whether the property value of judging the sign generic attribute MSISDN of the MSISDN clauses and subclauses of carrying among the LDAP Add Request occurred in present DIT, if then execution in step 103; Otherwise, execution in step 104.

Wherein, MSISDN items for information among the above-mentioned query directory inforamtion tree DIT; Judge that the step whether property value of the sign generic attribute MSISDN of the MSISDN clauses and subclauses of carrying among the LDAP Add Request occurred can be specially in present DIT: the index information of inquiry sign type clauses and subclauses; Whether the property value of judging the sign class clauses and subclauses of required increase thus occurred in this index information; This index information is the sign class clauses and subclauses and the property value of being preserved by amalgamation database thereof that in directory information tree, have existed, can in amalgamation database, store through the form of index information table, when increasing sign class clauses and subclauses newly at every turn; Amalgamation database upgrades this index information table, and the sign class entry index information in the present embodiment comprises the record of MSISDN entry attributes value;

Step 103: amalgamation database returns LDAP to Provision and adds failure response LDAP Add Response.

Step 104: amalgamation database increases corresponding clauses and subclauses according to the full DN of the MSISDN clauses and subclauses that increased in the LDAP Add Request request, returns LDAP Add Response success response and gives Provision.

After the increase operation of this MSISDN value in completing steps 104; Amalgamation database can also upgrade the index information of above-mentioned sign class clauses and subclauses; The MSISDN clauses and subclauses that increase newly and property value thereof are added in this index information; Whether the follow-up property value that can search index information when opening an account know sign type clauses and subclauses increased before, with the uniqueness of guaranteeing that type of sign clauses and subclauses are opened an account; If the index information of sign type clauses and subclauses is the mapping relations of record identification class entry attributes value clause name complete with it also; The full DN of the sign class clauses and subclauses of required increase carries out record in can also further LDAP Add Request being asked this moment in this index information; Can obtain the full DN of clauses and subclauses during the follow-up visit that increases, deletes, looks into, changes according to the MSISDN clauses and subclauses thus, be convenient to subsequent operation.The index information of sign type clauses and subclauses can adopt mode record in amalgamation database of index information table.

Referring to table 1, sign type entry index information signal table

In sum; Through above-mentioned steps 101 to 104; When opening an account, inquire about, it is out-of-date not occur in existing directory information tree at the property value of the sign class clauses and subclauses of confirming required increase, just increases (opening an account) accordingly and operates; Can guarantee the sign type uniquenesss of entry attributes value in directory information tree such as MSISDN clauses and subclauses, effectively avoid to guarantee in the prior art sign type not unique shortcomings of entry attributes value such as MSISDN clauses and subclauses.In addition; After increasing sign type clauses and subclauses; Amalgamation database is also set up sign type entry index information table; When can being used for follow-up operations such as increasing, delete, change, look into to this sign type clauses and subclauses, the property value of record identification class clauses and subclauses, and the mapping relations of the property value full DN corresponding with it, this index information table inquire about the full DN of these clauses and subclauses.

Those skilled in the art can know that in directory information tree, clauses and subclauses can comprise several attributes; For example; In the MSISDN clauses and subclauses, except above-mentioned sign generic attribute MSISDN, also has other attribute; Present embodiment is for the ease of explanation, and only the sign generic attribute with these MSISDN clauses and subclauses is that example describes.

Introduce the method for the data access that the embodiment of the invention provides below; The said data access of the embodiment of the invention mainly refers to operations such as the increase of sign type clauses and subclauses, deletion, modification, inquiries; Because available technology adopting LDAP access identities class clauses and subclauses; LDAP Server need know that the full access path of the sign class clauses and subclauses of required visit just can carry out corresponding operating; Promptly need know the full DN of this sign type clauses and subclauses; Prior art through visitor and database repeatedly alternant way obtain full DN, and the embodiment of the invention is guaranteed on the unduplicated basis of its property value when the increase operation (opening an account) of above-mentioned realization sign type clauses and subclauses, and the concrete implementation of two kinds of data accesses is provided: virtual A lias access mode and be the direct access mode of inlet with sign type clauses and subclauses; Wherein, be that the direct access mode of inlet can comprise again with sign type clauses and subclauses: in access interface, indicate access mode and discern access mode by ldap server analysis access path:

One, virtual A lias access mode

Virtual A lias access mode is meant when access identities class clauses and subclauses, conducts interviews through virtual route, and this virtual route is made up of the RDN of virtual A lias prefix and respective identification class clauses and subclauses.The foundation of virtual A lias realizes that through expansion RFC4512 agreement purpose is to set up a virtual path for sign type clauses and subclauses, so that the relevant visit of type of sign clauses and subclauses.

When using virtual A lias path to conduct interviews; LDAP Server (database) can at first analyze the access path information (being virtual route information) of carrying in the access request; If find to have virtual A lias prefix; Know it is virtual A lias access mode, confirm that promptly said access request is the access request based on sign type clauses and subclauses, then; LDAP Server knowing the pairing complete trails of virtual route of sign class clauses and subclauses to be visited, and then carries out the subsequent access operation through the sign class entry index information set up of inquiry.

Two, be the direct access mode of inlet with sign type clauses and subclauses

So-called is that the direct access mode of inlet is meant that the RDN (part path) according to sign type clauses and subclauses accomplishes the accessing operation that sign type clauses and subclauses are correlated with sign type clauses and subclauses; Virtual route need be provided with different being of virtual A lias access mode, only need provide the visit that RDN just can type of sign clauses and subclauses.

Enumerated two kinds of concrete implementation methods of this access mode below:

1, in access interface, indicates access mode

In the LDAP access interface, increase the access mode that respective identification is indicated this visit; Ldap server is analyzed the visit information that carries in the access interface; Thereby identify the access mode of this visit; If be the direct access mode of inlet with sign type clauses and subclauses; Confirm that promptly said access request is the access request based on sign type clauses and subclauses, so according to RDN (part path) the inquiry sign type complete trails (be full DN) of entry index information table that identifies type clauses and subclauses, the accessing operation of being correlated with at last to know these clauses and subclauses; If not, conduct interviews according to existing LDAP access mode.

To indicate the method for access mode to have multiple for expansion sign in the LDAP access interface, and the method for in the controls of LDAPMessage, expanding is referring to following specific embodiment.

2, analyze access path by ldap server and discern access mode

LDAP Server analyzes the access path information of carrying in the visit order, obtains last in an access path RDN; An if last root that RDN is not DIT in the access path; So just in the sign class entry index information that prestores, inquire about with this RDN value; If this information is arranged; Explain that this access mode is type is the direct access mode of inlet with sign, obtain access path (RDN) DN entirely accordingly then, the accessing operation of being correlated with again.

According to the property value of sign type clauses and subclauses unique characteristic in directory information tree; And guarantee on the basis that type of sign clauses and subclauses do not repeat to increase above-mentioned virtual A lias access mode and be that the direct access mode of inlet can not need between visitor and the LDAP Server repeatedly alternately and can obtain the sign class corresponding complete trailss of clauses and subclauses (DN) to be visited according to the part path that virtual route or visitor provide when the opening an account of sign type clauses and subclauses based on database with sign type clauses and subclauses.

For the method for data access that the invention described above embodiment is provided is carried out detailed explanation, being specially the MSISDN of HLR under using with sign type clauses and subclauses below is that example describes, and sees also following specific embodiment:

Referring to Fig. 3; The part DIT sketch map of setting up the HLR application of virtual A lias for MSISDN is provided, as shown in the figure, dc=AliasMsisdnPrefix; Dc=root " be the virtual A lias prefix of MSISDN class clauses and subclauses; can be through the sub-clauses and subclauses of dashed path visit MSISDN class clauses and subclauses and MSISDN class clauses and subclauses among the figure, wherein, the description of this virtual A lias can be accomplished through expansion RFC4512; according to the syntactic structure of extensions, partly use following field to be used for showing the virtual A lias prefix of MSISDN class clauses and subclauses at the extensions of DITContertRuleDescription:

AliasDNPrefixExtension＝

“X-AliasDNPrefix”SP?qdstring；aliasDN?pref

Use above-mentioned extended description MSISDN clauses and subclauses following:

Wherein, as stated, " X-AliasDNPrefix ' dc=AliasMsisdnPrefix, dc=root ' " promptly described the virtual A lias prefix of these MSISDN sign type clauses and subclauses.

Based on the virtual A lias access mode of MSISDN, concrete operation (comprise increase, deletion, revise and inquiry) is described in detail below:

A) the sub-entry operation of increase MSISDN

Wherein, Being specially IN service data CamelData with these sub-clauses and subclauses is that example describes, and referring to Fig. 3, desiring to increase RDN down in clauses and subclauses " MSISDN=13511111112; IMSI=4600311111112, dc=root " is the sub-clauses and subclauses of " CamelData=cameldata2 "; Because these " CamelData=cameldata2 " his father clauses and subclauses " MSISDN=13511111112 " to be increased are sign type clauses and subclauses, adopt virtual A lias access mode, referring to Fig. 4, the step that specifically increases operation is following:

Step 201:Provision sends to amalgamation database increases sub-item requests LDAP Add Request; Wherein, carry virtual route " CamelData=cameldata2, MSISDN=13511111112; dc=AliasMsisdnPrefix, dc=root " in this request.

Step 202: amalgamation database obtains virtual A lias prefix and MSISDN value after receiving LDAP Add Request request, according to the MSISDN value of obtaining, obtains the full DN of this MSISDN value.Be specially:

Amalgamation database is through asking to resolve to LDAP Add Request; Visit the prefix of its virtual route DN that carries, the virtual A lias prefix " dc=AliasMsisdnPrefix, dc=root " that identifies MSISDN knows that this visit is a virtual A lias access mode; Confirm that promptly said access request is the access request based on sign type clauses and subclauses; According to the property value " 13511111112 " of the sign generic attribute MSISDN of MSISDN clauses and subclauses, inquire about sign class entry index information signal table as shown in table 1, can obtain the corresponding full DN information " MSISDN=13511111112; IMSI=4600311111112, dc=root " of sign type clauses and subclauses.

Step 203: amalgamation database uses the full DN information replacement virtual route Alias of the MSISDN that obtains.Be specially:

Virtual route Alias " CamelData=cameldata2, MSISDN=13511111112, dc=AliasMsisdnPrefix; dc=root " is replaced with " CamelData=cameldata2; MSISDN=13511111112, IMSI=4600311111112, dc=root ".

Step 204: amalgamation database is carried out the increase operation of the sub-clauses and subclauses of MSISDN clauses and subclauses according to the access path that obtains after replacing, and returns the increase success response to Provision.Be specially:

Owing in step 203, the virtual route Alias in the LDAP Add Request request is replaced with " CamelData=cameldata2, MSISDN=13511111112, IMSI=4600311111112; dc=root "; So in this step 204, can carry out the increase operation of the sub-clauses and subclauses " CamelData=cameldata2 " of " 13511111112 " according to this access path after the replacement, wherein; The increase operation that can use prior art to support realizes, repeats no more.After having carried out the sub-entry operation of corresponding increase, return increase success response LDAP Add Response to Provision according to this full DN.

B) deletion MSISDN entry operation

It still is example with Fig. 3; Desire deletion sign type clauses and subclauses " MSISDN=13511111112, IMSI=4600311111112, dc=root "; After accomplishing deletion sign type clauses and subclauses; The information (like relevant information in the index information table) of the MSISDN clauses and subclauses that write down in the time of also need increasing clauses and subclauses through Provision deletion, referring to Fig. 5, it is following specifically to delete step:

Step 301:Provision sends LDAP deletion request LDAP Delete Request to amalgamation database; Wherein, Carry virtual route " MSISDN=13511111112, dc=AliasMsisdnPrefix, the dc=root of the MSISDN clauses and subclauses of desire deletion in this request.

Step 302: amalgamation database obtains virtual A lias prefix and MSISDN value after receiving LDAP Delete Request request, and according to the MSISDN value of obtaining, an inquiry sign type entry index information table obtains the corresponding full DN of this MSISDN property value.Be specially:

Amalgamation database is through asking to resolve to LDAP Delete Request; Visit the prefix in its virtual route that carries; Identify the virtual A lias prefix " dc=AliasMsisdnPrefix, dc=root " of MSISDN, again according to the property value " 13511111112 " of the sign generic attribute MSISDN of MSISDN clauses and subclauses; Inquire about index information signal table as shown in table 1; Can obtain the corresponding full DN information " MSISDN=13511111112, IMSI=4600311111112, dc=root " of sign type clauses and subclauses.

Step 303: the access path replacement virtual route Alias that amalgamation database uses the full DN information of the MSISDN that obtains to provide.Be specially:

Step 304: amalgamation database is according to the access path that obtains after replacing; After carrying out the deletion of MSISDN clauses and subclauses; Should identify information (like the index information) deletion of type clauses and subclauses " MSISDN=13511111112; IMSI=4600311111112, dc=root ", and return LDAP deletion success response LDAP Delete Response to Provision.

C) the sub-entry operation of deletion MSISDN

The operation of the sub-clauses and subclauses of deletion MSISDN and the deletion action of above-mentioned deletion MSISDN clauses and subclauses are basic identical:

At first, the virtual route Alias of the sub-clauses and subclauses of the desire deletion of amalgamation database reception MSISDN according to this virtual route and the index information that self writes down in advance, obtains the full DN of these sub-clauses and subclauses;

Then, according to the full DN of these sub-clauses and subclauses of obtaining, these sub-clauses and subclauses are carried out deletion action.Wherein, be noted that especially when carrying out the deletion action of these sub-clauses and subclauses, do not delete the index information of these MSISDN clauses and subclauses.

D) the sub-entry operation of modification MSISDN

This retouching operation is specially the retouching operation to the sub-clauses and subclauses of MSISDN.For example, referring to Fig. 3, the sub-clauses and subclauses " CamelData=cameldata2 " of " MSISDN=13511111112 " are revised as " CamelData=cameldata3 ", wherein, concrete retouching operation process and above-mentioned deletion action are similar:

Then, amalgamation database is carried out retouching operation according to the full DN of these sub-clauses and subclauses of obtaining to these sub-clauses and subclauses, is specially:

Amalgamation database is revised as " CamelData=cameldata3 " with " CamelData=cameldata2 ", thereby has successfully realized the retouching operation to the sub-clauses and subclauses of this MSISDN after getting access to the full DN " CamelData=cameldata2; MSISDN=13511111112; IMSI=4600311111112; dc=root " of these sub-clauses and subclauses.

E) the sub-entry operation of inquiry MSISDN

Similar with above-mentioned modification and deletion action, when carrying out query manipulation, amalgamation database is according to virtual A lias path and the index information that self writes down in advance, virtual A lias path is replaced with the full DN of MSISDN after, carry out corresponding query manipulation again.For example: referring to Fig. 3, the details of its sub-clauses and subclauses of desire inquiry MSISDN=13511111112, at this moment; After virtual A lias path " MSISDN=13511111112, dc=AliasMsisdnPrefix, dc=root " replaced with " MSISDN=13511111112; IMSI=4600311111112; dc=root ", according to " MSISDN=13511111112 can inquire the information content of its sub-clauses and subclauses.

In sum; To sign type entry attributes value unduplicated characteristic in directory information tree, the expansion ldap protocol is to identify sign type clauses and subclauses, to operations such as sign type clauses and subclauses increase, delete, look into, change the time; Can directly offer LDAP Server virtual route; LDAP Server knows it is virtual A lias access mode according to the virtual route that obtains, according to said virtual route inquiry sign type entry index information; Obtain the corresponding complete trails of this virtual route (full DN); Full DN according to obtaining operates accordingly, and the access method to sign type clauses and subclauses that the embodiment of the invention provided has avoided prior art to need repeatedly just can make LDAP Server obtain the full DN of clauses and subclauses to be visited alternately, has simplified the browsing process to clauses and subclauses.

To describe to the direct access mode that with the MSISDN clauses and subclauses is inlet below; With different being of virtual A lias access mode, this direct visit only need provide RDN (being the part path of clauses and subclauses to be visited) just can realize the accessing operation to sign type clauses and subclauses.

Referring to Fig. 6, providing with MSISDN is the direct access mode sketch map of inlet, and wherein, directly access mode comprises: in access interface, indicate access mode and analyze two kinds of situation of access path identification access mode.Under the particular content:

Mode one, in access interface, indicate access mode

This kind access mode need increase the indication that is used to indicate access mode in visit information; Thereby realize that amalgamation database is according to the visit information that carries the access mode indication that receives; Identify the concrete access mode of this visit; Confirm this and visit, can obtain corresponding complete trails according to the part routing information that carries in the visit information, and carry out corresponding accessing operation to after the direct access mode.For example; With the MSISDN clauses and subclauses is example; Amalgamation database judges that through analyzing visit information the access mode of this visit is not to be the direct access mode of inlet with the MSISDN clauses and subclauses, if; After then obtaining the full DN of these clauses and subclauses according to the property value of the sign generic attribute MSISDN of MSISDN clauses and subclauses, the accessing operation of being correlated with; Otherwise, then conduct interviews according to existing LDAP access mode.

For the access mode that in access interface, indicates that the embodiment of the invention is provided is carried out detailed explanation; Provided a kind of below through in the controls of LDAPMessage field, carrying out the method for extended access mode information; Realize utilizing and seeing for details as follows through the controlType in the controls field to indicating access mode:

Those skilled in the art can know that the reference format of the LDAPMessage that in RFC4511, defines is following:

Wherein, messageID is used for unique this LDAP message of sign in a LDAP session; Listed the operation that defines in the ldap protocol among the protocolOp, like increase, deletion, modification, inquiry etc.; Controls has been used to provide a kind of mechanism of expanding existing LDAP operation.Wherein, following among the RFC4511 to the definition of controls part:

Wherein, controlType is used for indicating control types; Criticality is used for showing the degree of danger of operation; When Provision nonrecognition control types, if its value with regard to shut-down operation, is returned error message for True; Otherwise, ignore this Control, proceed operation; ControlValue is used for indicating the concrete operations mode under this control types.

The inventor utilizes above-mentioned Control field when realizing the embodiment of the invention, be used for indicating access mode through expanding a Control, the concrete definition as follows:

AccessTypeFlagControl::＝SEQUENCE{

controlType 1.3.6.1.4.1.1466.1.2.100，

criticality BOOLEAN?DEFAULT?FALSE}

Wherein, utilize controlType to indicate access type, as stated, this controlType value is type to be the direct access mode of inlet with sign for 1.3.6.1.4.1.1466.1.2.100 shows., be that 1.3.6.1.4.1.1466.1.2.100 is an example with this controlType value, the embodiment of the invention does not limit the concrete value to this controlType.

Below in conjunction with shown in Figure 6 be the direct access mode sketch map of inlet with MSISDN, to describing based on the concrete operations (comprise increases, deletion, modification and inquire about) that with sign type clauses and subclauses are the direct access mode of inlet, particular content is following:

A) the sub-clauses and subclauses of increase MSISDN

Be that example describes to increase the sub-clauses and subclauses of IN service now at the MSISDN bar in the present embodiment.Referring to Fig. 6, desiring to increase RDN down in clauses and subclauses " MSISDN=13511111112, IMSI=4600311111112; dc=root " is the sub-clauses and subclauses of " CamelData=cameldata2 "; Because father's clauses and subclauses of these sub-clauses and subclauses are sign type clauses and subclauses " MSISDN ", adopting is the mode of inlet with sign type clauses and subclauses directly, the form realization that the RDN through providing sign type clauses and subclauses in increasing request and access mode are indicated; Referring to Fig. 7, concrete steps are following:

Step 401:Provision sends LDAP to amalgamation database increases request LDAP Add Request, wherein, carries path and access mode indication in this LDAP Add Request request.Be specially:
