A method for realizing real-name calling communication of multilogon domain includes setting URI searching server in special network with multiple SIP server, arranging logon domain corresponding table binding URI domain name/ IP address of each SIP server with unit name in URI server and arranging logon user table biding real name with user URI address in each SIP server to let user under different logon domain enable to utilize unit name to obtain bound URI domain name automatically and to utilize real-name to obtain bound URI address automatically as well as to launch a normal SIP call to URI address.

Description

Realize the communication system and the method for mutli-log-on field real name/real number calling
Technical field
The present invention relates to the communication technology that the user between the different log-on fields calls out mutually, particularly a kind of communication system and method that realizes mutli-log-on field real name/real number calling, this communication system and method are suitable for the calling of PC2PC and the calling that 3G mobile is undertaken by the mobile Internet online, and the mutual calling between PC and the 3G mobile.
Background technology
SIP (Session Initiation Protocol RFC3261) communication protocol is an international standard communication protocol, and it is the core communication protocol of Next Generation Internet.This agreement itself is supported single log-on field communication, also supports the communication of many log-on fields.So-called log-on field is the zone of leading subscriber in logic, and general same registration intra domain user can be searched for mutually, adds mutually, is presented at line states etc.; The user of different log-on fields can not search for mutually.According to the regulation of Session Initiation Protocol, the user between the different log-on fields need (Unify Resource Identifier)/the IP address be carried out mutual calling and is communicated by letter by URI.
About using URI to communicate between different log-on fields: the form of URI is just as our e-mail address, for example: xxx@hotmail.com, for the convenience of narrating, this paper also is called the URI address, the former is individual's a sign to occupy @, occupying the @ latter is the domain name (for the convenience of narrating, this paper also is called the URI domain name) of place log-on field.URI URI address in other words can not weigh at this log-on field and even the whole network, that is to say it is unique.With regard to this network, each user has the not heavy URI in a whole world.Session Initiation Protocol allows the user to use the URI/IP address to make a call.But the user also is unaccustomed to remember the URI/IP address, causes the inconvenience on writing to each other thus.
About using the IP address to communicate between different log-on fields: because the both sides of communication are difficult to know the other side's IP address (comprising inside and outside net IP address) in advance, so very difficultly call out and communicate by letter according to this kind mode.
In addition, communicate about using the URI address between different log-on fields: know in advance because the URI of communication counterpart is very difficult, so use very inconvenient.
The inventor thinks, can carry out each other calling by the mode of " real name/real number " if allow between the user of different log-on fields, and needn't directly use the URI/IP address again, and that bring great convenience can for undoubtedly writing to each other of people.Real name/real number not only frequency of utilization is higher, and meets people's memory habit.
Real name: constitute by two parts of " organization " and " Real Name ".
Real number: constitute by two parts of " organization " and " true telephone number/phone number/extension ".
In people's communication custom, real name/real number is the most often used and remember.
Summary of the invention
The present invention is directed to the defective or the deficiency that exist in the prior art, a kind of communication system and method that realizes mutli-log-on field real name/real number calling is provided, this communication system and method are suitable for the calling of PC2PC and the calling that 3G mobile is undertaken by the mobile Internet online, and the mutual calling between PC and the 3G mobile, allow between the user of different log-on fields and can carry out each other calling by the mode of " real name/real number ", and needn't directly use the URI/IP address again, thereby bring convenience for writing to each other of people.
Technical conceive of the present invention is, by in having the private network of many sip servers, disposing the URI search server, be provided with the log-on field correspondence table that the URI domain name/IP address and the organization of each sip server are bound in this URI search server, be provided with the registered user table (being database structure) that user's Real Name and/or telephone number and this user's URI address is bound in described each sip server, make and to utilize organization in the URI search server, to obtain constituting of its binding automatically between the user of different log-on fields by two parts of " organization " and " Real Name ".The URI domain name is utilized Real Name and/or telephone number to obtain the user URI address of its binding automatically at destination server again, and a normal SIP is initiated in this URI address call out, thereby brings convenience for writing to each other between the user of different log-on fields.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Implication about " real name/real number calling " is described below:
Real name calling: the user realizes same log-on field customer call by input " Real Name " in same log-on field.In different log-on fields, realize the customer call of different log-on fields by input " organization (or abbreviation)+Real Name ".
Call out for real number: realize pc user's calling by real " organization (or abbreviation)+telephone number, extension, phone number ".Can not import " organization (or be called for short) " yet and carry out at " URI search server " directly that number is resolved, the mode of broadcast query is finished call.
Realization principle from " real name/real number " method of calling, it is the URI information that obtains the other side by the mode of " real name/real number ", according to this URI information, initiating a real SIP and call out then, is not that customer call is carried out in direct use " real name/real number " in Session Initiation Protocol.
As shown in Figure 3, Fig. 3 is the interface schematic diagram of real name/reality call applications, for the user, as long as they import the URI that " real name/real number " just can obtain the other side automatically on user interface, system calls out this URI automatically, and the user can select this URI is saved in this locality, searches this URI later on no longer at every turn.
Realize " real name/real number " call function, obviously must finish " Real Name ", " true telephone number (comprising the binding of phone number, home phone number, office telephone, extension etc.) " and URI, to such an extent as to want corresponding mutually, mapping.When opening an account application and database design, the user finishes the correspondence of above-mentioned functions, so that in actual motion, realized.For example, open an account the user and to fill in when application, just require the user to import Real Name and telephone number, thereby in customer data base, realize the binding of URI and these information.The further exploitation of " URI search server " and client just can be set about carrying out in the basis that above binding information has been arranged.
The functional description of " real name of many log-on fields, the multinode/real number calling " client among the present invention: 1. client is sent search purposes server ip address/URI request according to " organization " to " URI search server "; 2. the inquiry URI that sends at " Real Name ", " true number " to " destination server " asks; 3. the prompting user obtains URI and is saved in this locality " personal address book " later on, initiates a normal SIP according to this URI and calls out.
The setting of URI search server: in private network, place one " URI search server ", be used to search for the IP address/URI in corresponding " target registered territory ".Every function that " URI search server " possesses: 1, accept searching request that client sends after, by the corresponding IP address/URI of " log-on field correspondence table " search " organization ", and result for retrieval informed.2, when " new registration territory " appears in private network, in time add " log-on field correspondence table " to.
Fig. 2 is for using private network schematic layout pattern of the present invention, as shown in Figure 2, the communication system of realization mutli-log-on field real name/real number calling of the present invention, be included in many sip servers that are deployed in each node in the private network respectively, described many sip servers are connected with the URI search server respectively, be provided with the log-on field correspondence table that the URI domain name/IP address and the organization of each sip server are bound in the described URI search server, be provided with registered user's table that user's Real Name and/or telephone number and this user's URI address is bound in described each sip server, make and to utilize organization to obtain the URI domain name of its binding automatically between the user of different log-on fields, utilize Real Name and/or telephone number to obtain the URI address of its binding automatically again, and a normal SIP is initiated in this URI address call out.Described communication system also has following function: after this URI address being initiated a normal SIP calling, if call out obstructed, then transfer to carry out the IP phone calling of PC2Phone with the telephone number of its binding, from being positioned at the top of Fig. 2, can see public network INTERNET and the IP phone gateway that is arranged on the public network.
Described communication system also has following function: after utilizing Real Name and/or telephone number to obtain the URI address of its binding automatically, the prompting user is saved in local " individual contact person ", so that removal search URI again when using next time; A normal SIP calling is initiated in this URI address to be carried out automatically by communication system; For real number calling, can directly carry out number according to telephone number and resolve, and finish call in the mode of broadcast query at the URI search server.
Registered user's table comprises Real Name, unit one belongs to, registered user name, e-mail address and binding phone, except essential information, also comprise details, can also comprise user images, the department of unit one belongs to, user cipher adds phone etc., and the information of adding the binding phone comprises: phone type, area code, telephone number, extension etc.The log-on field correspondence table comprises full name and/or abbreviation, log-on field or URI domain name and the IP address of organization.
Log-on field correspondence table in the URI search server:
Organization Be called for short 1 Be called for short 2 Log-on field The IP address
Lidefeng Communication Technology Co., Ltd., Beijing Profit moral Feng company Sharp moral Feng @ldf.com 219.239.34.52
Our innovative point is: can carry out each other calling by the mode of " real name/real number " between the user of different log-on fields, and needn't use the URI/IP address.
What our " real name/real number " mode was at first finished is the calling of a PC2PC.When " real number calling ", if can differentiating PC2PC, system can not carry out, promptly transfer the PC2Phone call ip phone to this telephone number.
Because the appearance of 3G mobile, mobile phone itself is built-in Session Initiation Protocol stack etc.Be the equal of a PC, so let us also support 3G mobile to finish above function by the mobile Internet online.
The inventor is on the version basis of existing single node, single log-on field, start to develop under " multinode, many log-on fields " " real name/real number call out " function, the inventor proposes the innovation that basic condition that this demand is based on existing multimedia communication software is made.
Fig. 4 realizes the flow chart of mutli-log-on field real name/real number calling for the present invention, the communication means of realization mutli-log-on field real name/real number calling as shown in Figure 4, comprise URI search server, destination server, source client and destination client, calling between this two client may further comprise the steps: step 1, and the source client is initiated searching request by organization to the URI search server; Step 2, the URI search server returns Search Results to the source client, promptly with the URI domain name/IP address of described organization binding; Step 3, the source client is initiated retrieval request by Real Name and/or telephone number to the destination server of this URI domain name/IP address; Step 4, destination server returns result for retrieval to the source client, promptly with the URI address of the destination client of described Real Name and/or telephone number binding; Step 5, the source client realizes that by this URI address and destination client SIP communicates by letter.
Sharp moral Feng in step 1 and the step 2 is the abbreviation of Lidefeng Communication Technology Co., Ltd., Beijing, and the IP address of sharp moral Feng for example is 219.239.34.52, and the log-on field of sharp moral Feng is @ldf.com.If replying, this unit not, URI search server say " not this unit ".Zhao Liang/telephone number in step 3 and the step 4 is a real name/real number, and zl@ldf.com is the URI of the sharp moral Feng Zhao Liang of company.Set up SIP communication by this URI.This shows that real name calling is meant: at different log-on fields, input " organization "+" Real Name " searched " organization " corresponding the other side's server ip address to " URI search server ".Real number calling is meant: at different log-on fields, input " organization "+" telephone number+extension ", " phone number " are searched " organization " corresponding the other side's server ip address to " URI search server ".In addition, " URI search server " address of the whole network is left client in advance in, has only one usually.In search procedure for " real name retrieval " " visible user " authority in addition.Do not add the authority restriction for " real number calling ".After the user obtains URI, point out in " other unit " that the user directly is saved in local " my contact person " removal search URI again so that use next time.If " real number calling " then will point out input " the other side's name " before preservation.
This method is applied in the private network, and when occurring the new registration territory in the private network, described URI search server adds it to the log-on field correspondence table immediately.
Should be pointed out that the above embodiment can make those skilled in the art more fully understand the present invention, but do not limit the present invention in any way.Therefore, although this specification has been described in detail the present invention with reference to drawings and embodiments,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technical scheme and the improvement thereof of spirit of the present invention and technical spirit, and it all should be encompassed in the middle of the protection range of patent of the present invention.
