Specifically, when the server that inquiry request is received in the embodiment of the present invention is the two grades of E.164 Number server in source, two grades of source E.164 Number server searches whether the user data that there is called subscriber in the data area that label is indicated.If called subscriber number The server of the ownership place of code is not two grades of source E.164 Number server, then two grades of source E.164 Number server is searched less than with called subscriber's The corresponding user data of number, now, the inquiry request is forwarded to one-level E.164 Number server by it, to cause that one-level ENUM takes Business device carries out user data query according to the inquiry request, and one-level E.164 Number server is after Query Result is obtained by the Query Result It is forwarded to two grades of source E.164 Number server；If the number of called subscriber belongs to the E.164 Number server management of two grades of source, two grades of source ENUM Server searches whether the SIP URI that there is the number of called subscriber in the data area that label is indicated, if in the presence of obtaining The SIP URI of the number of the called subscriber, wherein, the SIP URI of the number of called subscriber in the E.164 Number server of two grades of source to deposit A part in the user data of the called subscriber of storage.

It is exemplary, for ownership place is for the called fixed telephone number B (02112345678) in Shanghai, exist with Under several situations：

(1) in the scene of user's call number B in Shanghai, included in the inquiry request that Shanghai E.164 Number server is received Have number B and indicate to carry out the label of user data query in the second data area, Shanghai E.164 Number server according to number B, Inquiry whether there is the corresponding user data of number B in the second data area of Shanghai E.164 Number server, when B numbers are During IMS user, the Query Result that Shanghai E.164 Number server is obtained is the SIP URI of number B (for example, SIP:862112345678@ shanghai.ims.cn)；When B numbers are non-IMS user, the Query Result that Shanghai E.164 Number server is obtained is for " without this use Family ".

(2) in the scene of Pekinese user call number B, E.164 Number server inquiry in Beijing is corresponding less than number B Data, and number B is not belonging to the number of Beijing E.164 Number server management, inquiry request is forwarded to one-level by Beijing E.164 Number server E.164 Number server, to cause that one-level E.164 Number server obtains Query Result according to the inquiry request.

Further, when the server that inquiry request is received in the embodiment of the present invention is one-level E.164 Number server, one-level E.164 Number server searches whether the user data that there is called subscriber in the data area that label is indicated.

If specifically, label indicates to be carried out in the first data area in the inquiry request that receives of one-level E.164 Number server Data query, then one-level E.164 Number server the extension SIP URI (quilts of the number of called subscriber are obtained in its first data area Being the extension SIP URI of the number of user includes the SIP URI and ID of the number of called subscriber, and the ID is used for Show not determining whether the user is IMS user, because the user data stored in one-level E.164 Number server is called subscriber's Number and the area code of the number of the corresponding relation or called subscriber of domain names and the IP address of ownership place server, it is optional , ID can be user=phone).

Wherein, when the number of called subscriber is phone number, one-level E.164 Number server root in its first data area The extension SIP URI of phone number are got according to the corresponding relation of H yards, ownership place area code and home network domain name；When called use When the number at family is fixed telephone number, one-level E.164 Number server is in its first data area according to area code and home network domain The corresponding relation of name gets the extension SIP URI of fixed telephone number.

If label indicates to carry out data in the second data area and look into the inquiry request that one-level E.164 Number server is received Ask, then one-level E.164 Number server in its second data area according to two grades of IP address of E.164 Number server of area code and ownership place Corresponding relation obtain two grades of IP address of E.164 Number server of purpose, and inquiry request is forwarded to two grades of ENUM of purpose services Device, to obtain Query Result.

Exemplary, if the number of called subscriber is the phone number 133H0H1H2H3ABCD in Shanghai, one-level ENUM services User is carried out in the first data area comprising phone number 133H0H1H2H3ABCD and instruction in the inquiry request that device is received The label of data query, then one-level E.164 Number server according to the inquiry request in its first data area according to mobile phone H yards, return Possession area code obtains extension SIP URI with the corresponding relation of home network domain name：sip:86133H0H1H2H3ABCD@ Shanghai.ims.cn, user=phone.

Further, in the embodiment of the present invention receive inquiry request server for the purpose of two grades of E.164 Number server when, mesh Two grades of E.164 Number server the user data that there is called subscriber is searched whether in the data area that label is indicated.If called use Family is IMS user, then two grades of E.164 Number server of purpose obtain the SIP URI of the number of called subscriber.

Server is sent to call-processing arrangement the Query Result after Query Result is got.

Server is sent to corresponding call-processing arrangement the Query Result after Query Result is got, to carry out Follow-up route.Wherein, Query Result is used to characterize the routing mode that the affiliated networking of server uses, and call-processing arrangement is being obtained After the Query Result sent to server, corresponding routing mode is chosen according to the Query Result and is subsequently route.So, During the non-IMS user speech business intercommunication in IMS user and strange land, no longer only with a kind of routing mode.

Exemplary, if the IMS user in Shanghai calls the non-IMS user in Beijing, and the Query Result that Shanghai CSCF gets During for " without this user ", according to " without this user ", this Query Result routes the call to PSTN network to Shanghai CSCF, and passes through PSTN nets route the call to Pekinese's PSTN network, and the routing mode is " going out IMS network nearby "；If the IMS user in Shanghai The calling non-IMS user in Beijing, and the CSCF Query Results that get in Shanghai are when including Pekinese's domain names, Shanghai CSCF roots To be called according to Pekinese's domain names and Pekinese's IMS network is routed the call to by IMS nets, then by Pekinese's IMS nets Network routes the call to called subscriber, and the routing mode is " just far going out IMS network ".

Specifically, after two grades of source E.164 Number server gets Query Result, the Query Result is sent to Calling Side network element Equipment, so that Calling Side network element device is subsequently route according to Query Result；One-level E.164 Number server gets Query Result Afterwards, the Query Result is sent to two grades of source E.164 Number server, so that Query Result is forwarded to master by two grades of source E.164 Number server It is side network element device；After two grades of E.164 Number server of purpose get Query Result, the Query Result is sent to callee side network element Equipment, so that callee side network element device is subsequently route according to Query Result, or, two grades of E.164 Number server of purpose get After Query Result, the Query Result is sent to one-level E.164 Number server, in order to one-level E.164 Number server by the Query Result Two grades of source E.164 Number server is forwarded to, and then is eventually sent to Calling Side network element device.

Further, in order to describe looking into the user data in each E.164 Number server in network system in detail Ask, now to the inquiry of user data in two grades of source E.164 Number server, two grades of E.164 Number server of one-level E.164 Number server and purpose It is illustrated.
