Abstract

A method of inquiring called user in packet domain includes utilizing means of combining telephone number with E - MAIL address to inquire called address i .e dividing telephone number to be two sections with one section being used to present user name and another section being used to present application server storing user information when telephone number character is used to realize data service in packet domain .

Description

A kind of in packet domain the called method of inquiry

Technical field

The present invention relates to communication technical field, be meant that especially network side inquired called method when the caller phone terminal was initiated data service in packet domain.

Background technology

" PULL " mode is generally adopted in data service in the packet domain at present, so-called " PULL " mode, be exactly that the user initiatively sets up earlier data service and connects, connect, and sign in to and browse or download oneself interested content on certain WEB website or the server as the link protocol (PPP) of point-to-point.

For some data service, need network initiatively to descend photos and sending messages to give the user, promptly need applied business server (AS) initiatively to seek the called subscriber, connect with the data service of setting up between calling and called, and the called subscriber receives information in passive mode.In the data service of packet domain, existing network side is mainly used following dual mode and is inquired called:

A kind of mode is to called according to called subscriber's IP address lookup.Specific implementation is: the called subscriber sets up data service and is connected in advance with between the network side, and sign in on specified web or the application server, this website or application server are just noted this called subscriber's IP address like this, when connection request is initiated in caller, network side just can be found called IP address easily, connects to called initiation data service.As VOIP (Voice over IP), video telephone etc.Most typical example is exactly the usual business of using such as OICQ, ICQ, has also logined the QQ server with prerequisite the other side of certain " good friend " communication, could start literal like this, the communication of voice or video, otherwise just can't with its communication.

The limitation of above-mentioned implementation is: network side can only just can find called by called institute's Website login or application server, that is to say that network side must be known called data service address in advance, and promptly the called subscriber just can be found in the IP address.But under the more susceptible condition, the called subscriber may not set up data service in advance and connect, even perhaps set up the data service connection, but do not sign in on specified web or the application server, at this moment, network side is not known called IP address, also just can't with its communication.As seen, though said method calling subscriber's input information is not required, the network side user that can not find the called probably, particularly in the communication of individual, particularly evident to the individual.

Another kind of mode is that Email (E-MAIL) address lookup according to the called subscriber arrives called.Specific implementation is: the calling subscriber imports called subscriber's complete E-mail address, name server in the network (DNS) is according to the domain name part of E-MAIL address, it is the part behind the @, parse the IP address of this user place application server, like this, can find the application server that has the called subscriber affiliated easily, after call request message is routed to the application server that has called address information, this server partly is a part before the @ according to E-MAIL address user name again, is redirected to the called subscriber.

Though above-mentioned implementation method can make network side be relatively easy to find the called subscriber, the called party information of calling subscriber's input there is strict demand, promptly the calling subscriber must import called E-MAIL address, and network side just can inquire called.The limitation of the method that above-mentioned inquiry is called is: only be suitable for the operation of computer user.And require the telephone terminal user, and no matter be mobile telephone terminal users or fixed telephone terminal user, import called E-Mail address, not only do not meet people's daily use habit, and input is also very inconvenient.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of called method of inquiring about in packet domain, when data service was initiated in caller, it was called to guarantee that network side inquires in packet domain.

For achieving the above object, technical scheme of the present invention is achieved in that

A kind of in packet domain the called method of inquiry, this method may further comprise the steps:

A, calling terminal receive user input treat applied business type and called phone number MDN after, be converted into the form of e-mail address, and with the email address format of this conversion as called sign, initiate to comprise the call request of called identification to network side;

After b, network side receive call request, resolve the IP address of this called institute attribution server according to the domain name part of called identification, this call request is routed to the called server that belongs to by domain name server (DNS);

C, the called server that belongs to find the called subscriber according to this MDN after the called identification of email address format is converted to telephone number MDN form.

Preferably, the described method that applied business type and telephone number MDN are converted to the form of e-mail address for the treatment of with user input is: number section of expression Subscriber Number among the MDN as user name, will be removed all numbers section of expression Subscriber Number and the type of service domain name as e-mail address among the MDN.

Preferably, the figure place of number section of expression Subscriber Number is configured according to practical application among the described MDN.

Preferably, this method further comprises: the suffix that increases the expression operator name in the domain name of e-mail address.

Preferably, described calling terminal is mobile telephone terminal or fixed telephone terminal.

Preferably, described called phone number is the telephone number of mobile phone or the telephone number of landline telephone.

The present invention utilizes the characteristic of telephone number, when packet domain realizes data service, adopts the method for telephone number and the combination of E-MAIL address to inquire about called address.Be calling terminal receive user input treat applied business type and called phone number MDN after, be converted into the form of e-mail address, and with the email address format of this conversion as called sign, initiate to comprise the call request of called identification to network side; After network side receives call request, resolve the IP address of this called institute attribution server according to the domain name part of called identification, this call request is routed to the called server that belongs to by domain name server (DNS); The called server that belongs to finds the called subscriber according to this MDN after the called identification of email address format is converted to telephone number MDN form.

Use the present invention, both met user's use habit, made things convenient for calling subscriber's input, make network side can fast find the called subscriber exactly again, and, can also be according to the requirement of operator, the title of operator is joined in the suffix of address.The present invention has promoted data service the carrying out at telephone terminal of packet domain.

Embodiment

For making technical scheme of the present invention clearer, the present invention is done detailed description further again below in conjunction with instantiation.

Each number section of existing telephone number all has certain implication, below simply introduce earlier the implication of each number of telephone number section.

Suppose that certain cell-phone number is 8613345678888, the implication of its each number section is as follows usually: top two is country code, and China uses 86; Back to back three " 133 " are Mobile Access Codes, the network No. scheme that is promptly adopted, and the CDMA of UNICOM is 133; Thereafter four " 4567 " are attaching position register (HLR) identification codes; Last four " 8888 " are mobile subscriber numbers, are distributed voluntarily by each HLR.

Suppose certain fixed telephone number 86075588889999, the implication of its each number section is as follows usually: top two is country code, and China uses 86; Back to back four " 0755 " expression area code, four " 8888 " expression offices number thereafter; Last four " 9999 " expression Subscriber Number is distributed voluntarily by each innings.

According to the above-mentioned characteristic of telephone number as can be seen, for any telephone number, number section of an expression Subscriber Number is arranged all, number section of this user attaching position of expression.

Thinking of the present invention is: utilize the characteristic of telephone number, when packet domain realizes data service, adopt the method for telephone number and the combination of E-MAIL address to inquire about called address.Be about to telephone number and be divided into two sections, make the number segment table of expression Subscriber Number in the telephone number show E-MAIL address user name, make all number segment tables of removing the expression Subscriber Number in the telephone number show the application server of preserving user profile.The specific implementation method is as follows:

When certain caller phone terminal use initiates the data service connection request, only need input called phone number to identify called, afterwards, this caller phone terminal is converted to the called phone number mark sign of E-MAIL form, simultaneously in the domain name of E-MAIL, add different suffix, to divide into the different server address at the selected different service types of calling subscriber.This address suffix pre-sets in calling terminal.The DNS of network side goes out application server IP address, called place and this connection request is routed to this server according to the domain name mapping behind the @ easily according to the called address of E-MAIL form.At this moment, the called server that belongs to finds the called subscriber according to this MDN after the called identification of email address format is converted to telephone number MDN form.

Specify for example below.

Dispose the pairing suffix name of type of service in certain calling subscriber's the terminal, as disposed the suffix of the professional corresponding .voip of VOIP, the suffix of the corresponding .video of visual telephone service; And, demand according to operator, can make the corresponding different suffix name of title of different operators, as dispose the suffix of 86133 corresponding .chinaunicom, the suffix of 86139 corresponding .chinamobile, the suffix of other corresponding .chinatelcom, called subscriber's number is 8613345678888, like this, if this calling subscriber wishes to use the VOIP business, then its pairing suffix is 861334567.chinaunicom.voip.cn, if this calling subscriber wishes to use visual telephone service, then its pairing suffix is 861334567.chinaunicom.video.cn.In the present embodiment, suppose that this calling subscriber wishes to use the VOIP business, its implementation procedure is as follows:

Above-mentioned calling subscriber's mobile phone terminal receive calling subscriber input treat applied business type and called number 8613345678888 after, automatically the sign with this called subscriber is converted to 8888@861334567.chinaunicom.voip.cn, afterwards, use this called subscriber's sign to the network side request of making a call.

After network side receives above-mentioned call request, according to the IP address that the domain name 861334567.chinaunicom.voip.cn of CSI called subscriber identification 8888@861334567.chinaunicom.voip.cn parses this called affiliated application server, this call request is routed to this called affiliated application server by DNS.

After application server under called is converted to MDN form 8613345678888 with the called identification of this E-MAIL address format, inquire this called subscriber according to the called identification of this MDN form.

So far, network side has inquired the called subscriber quickly and easily according to the called MDN of calling subscriber's input.

At the foregoing description, if called subscriber's number is 86075588889999, and the calling subscriber wishes to use visual telephone service, and its implementation procedure is as follows:

Calling subscriber's mobile phone terminal receive calling subscriber input treat applied business type and called number 86075588889999 after, automatically the sign with this called subscriber is converted to 9999@8607558888.chinatelcom.video.cn, afterwards, use this E-MAIL address as called subscriber's sign to the network side request of making a call.

After network side receives above-mentioned call request, according to the IP address that the domain name 8607558888.chinatelcom.video.cn of CSI called subscriber identification 9999@8607558888.chinatelcom.video.cn parses this called affiliated application server, this call request is routed to this called affiliated application server by DNS.

After application server under called is converted to MDN form 86075588889999 with the called identification of this E-MAIL address format, inquire this called subscriber according to the called identification of this MDN form.

In the above-described embodiments, do not have the server address of operator's sign if operator requires sign, correspondingly, calling terminal is converted to 8888@861334567.voip.cn with the called identification that receives, or 9999@8607558888.video.cn gets final product.

Above-mentioned calling terminal is that portable terminal is that example describes with mobile phone terminal, and certainly, calling terminal also can be a fixed telephone terminal.

Because the telephone number branch is mixed last four the representative of consumer numbers of more usefulness at present, therefore, more than be that last four bit representation Subscriber Numbers with telephone number are that example describes, certainly, also can wait and represent user name, be applicable to the situation of different representative of consumer numbers with last three or five.

In addition, if when a server comprises a plurality of innings numbers number segment, the expression Subscriber Number also may comprise multidigit, that is to say, the figure place of number section of expression Subscriber Number is unfixed, can be configured according to practical application, but no matter how the telephone number front and back are divided into for two sections, all are applicable to scheme of the present invention.

The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
