Therefore, the present invention can also simplify the dialing operation when users send callings.
Description
Technical field
The present invention relates to the communications field, be meant a kind of method of calling Internet device especially.
Background technology
There is the equipment of many support voice communications the Internet at present, these internet devices are supported instant messaging (IM, Instant Message), need carry out voice intercommunication with plain old telephone, described voice intercommunication comprises dual mode, a kind of is that internet device is called out plain old telephone, and promptly internet device is done caller (PCto Phone); A kind of is the common telephone call internet device, (Phone to PC), and promptly internet device is done called.Relate generally to internet device among the present invention and make called situation, be described in detail below.
For the Internet (Internet) user who uses the phone online, it is quotidian once going up and taking the telephone line several hrs in the network process, like this, will inevitably miss many incoming calls, like this, the user is for avoiding missing incoming call, the telephone line of having to apply in addition, thus, the user is desirable to provide the business of a kind of call notification and control, make the Internet user in online, monitor and to handle to incoming call, this business can be by the ip intelligent peripherals (IP) of intelligent network, modes such as Centrex provide, its basic implementation procedure is as follows: the user at first applies for busy call/no-answer diversion operation base, during when incoming call and to busy tone, this incoming call is forwarded on the internet call manager (IMP), the internet call manager is collected relevant call forward information calling party and callee, shine upon then, be retrieved as Internet protocol (IP) address of user's dynamic assignment by signaling information, if this user is online and have the IP address, just call line identification information is sent to the user by the Internet.Like this, called subscriber's internet device will demonstrate information such as calling number, name, and at this moment, the Internet user can carry out current talking (VoIP) by the loud speaker and the microphone of internet device.
More than be the implementation procedure that internet call waits for that (ICW, Internet Calling Waiting) is professional.The ICW business also has the characteristic that far-end is called out control, can make the personnel that work at home monitor the phone of office at home in real time.The ICW business is to erect the bridge of real-time communication between the Internet and public switched network, and the call completing rate of calling can be provided, and the current any business that provides is not provided, and has solved the user can't answer any incoming call by the telephone line online problem.
According to the intercommunication system, as shown in Figure 1, the basic all devices function that keeps in the intelligent network in interworking architecture, three gateway function entities are set: calling/carrying control gateway (C/BGF between two networks, Call/Bearer Gateway Function), Service Control Gateway (SCGF, ServiceControl Gateway Function) and management gateway (MGF, Management GatewayFunction), correspond respectively to calling/bearer control layer, service control layer and management level, realization is based on the intelligent network business signaling of intelligent network application part agreement (INAP) and based on the protocol conversion between the IP telephony network signaling H.323, thereby realizes the IWF of two networks on each aspect.Because C/BGF, SCGF and MGF three's effect and the function of finishing are had nothing in common with each other, therefore, three's residing physical location in network is also different, for example, C/BGF can be in the position of Internet connector (IAP, Internet Access Provider) usually, and SCGF and MGF can be arranged in Internet connector position, a server that also can be used as in the ISP (ISP, Internet ServiceProvider) is disposed.
The interactive operation between IP server and the intelligent network SCP is promptly finished in intercommunication between the service control layer of SCGF realization intelligent network and IP network, and the SSP of IP network side and the interoperability between the intelligent network SCP, finishes work such as signaling protocol conversion.At service control layer, the function that SCGF need have comprises: SCGF need have the function of carrying out intercommunication with the PSTN (PSTN) of IP network side and the Internet intercommunication (PINT) server, after IP network side user's PINT class service request is carried out protocol conversion, be passed to the SCP of PSTN side, carry out actual business control by SCF; SCGF also need have the ability with H.323 gatekeeper (SSP) intercommunication of IP network side, with the IP network side H.323 terminal send after IP network/protocol conversion is carried out in the request of PSTN interworking service, be passed to the SCP of PSTN side, carry out actual business control by SCF; SCGF also need have the function with the service condition change information notice IP network side server of intelligent network side, and the function of the control information of intelligent network side SCP being notified IP network side gatekeeper.
Here, the concrete analysis service control gateway function relevant with the PINT server.On the one hand; after SCGF receives the service request of IP network side PINT server transmission; send it to service control function (SCF; Service Control Function); what meanwhile be sent to SCF also comprises some necessary informations; so that SCF controls service request, authenticated user and authorization data, and the protection intelligent network is not subjected to misuse and erosion from the Internet.On the other hand, SCGF will be sent to the IP network side from the instruction of SCF, carry out professional for it.For the Internet, SCGF has hidden SCF and special resource function (SRF, Special Resource Function), plays a part mediation device between IP network and intelligent network, helps the simplification of the Internet side interface.From IP network application user's angle, SCGF is to the service feature processing of request and carry out responsible; The functional entity of intelligent network lies in after the SCGF, and its operation is transparent for the IP network user.
C/BGF is equivalent to the comprehensive entity of media gateway and medium control gateway, and and if only if a side user just need when the Internet Protocol telephone, the function that C/BGF need support comprises: be equivalent to media gateway, realize the speech coding conversion between bearing bed PSTN and the IP network; Be equivalent to SGW, realize the intercommunication of Signaling System Number 7 and IP network agreement among the PSTN, finish the bridging functionality of Internet Protocol telephone and pstn telephone; Be equivalent to medium control gateway (MGC), realize Signaling System Number 7 and protocol conversion H.323, and by the control of corresponding protocol realization to calling out and carrying.
MGF is the gateway function entity that is provided with for administrative purposes, thereby its basic function is the intercommunication between short message service (SMS) center of the office terminal of realizing IP network side on the SML and intelligent network, mainly comprise support based on World Wide Web (WWW) (WEB) management service, to the retrieval of data, modification in the heart among the SMS, also comprise the authentication that management is asked, the management interface that authenticates and provide user data as the IP network user; The conversion of gateway protocol and the realization of corresponding security mechanism.IP network user can download to user's customization data in the service data function (SDF, Service data Function) of intelligent network by MGF.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Among the present invention, the corresponding relation in network between storage Custom Number and the IM sign, when internet device made a call, the corresponding IM of the Custom Number of NetFind and calling identified, and foundation is connected with calling between the internet device then.Internet device described in the present invention can be the terminal in the flexible exchanging network, also can be equipment, the computer of online, or the like.
The user can be provided with the corresponding relation between Custom Number and the IM sign, this corresponding relation of the network storage then by the Web server of operator.Web server can at first carry out authentication to the user, if the user by authentication, then allows the user that the corresponding relation of Custom Number between identifying with IM is set; If the user is not by authentication, then refusing user's is provided with the corresponding relation between Custom Number and the IM sign.It is corresponding with the IM sign that the user can directly be provided with Custom Number by Web server, also can provide IM sign to Web server by the user, generated with this IM automatically by Web server then and identify corresponding Custom Number.The user is provided with Custom Number and IM by Web server and identifies when corresponding, Web server can further be judged based under this user ID, whether be provided with and the corresponding IM sign of this Custom Number, if the IM that then points out the user to reselect with Set For Current identifies corresponding Custom Number; Otherwise, the corresponding relation between the Custom Number of storage Set For Current and the IM sign.The user can make amendment to the corresponding relation between Custom Number and the IM sign by Web server, also can increase or reset corresponding relation between Custom Number and the IM sign, the corresponding relation between also Custom Number that can be provided with by the Web server deletion and IM identify by Web server.
In addition, the system that is provided with that the user also can provide by operator is provided with system as phone operation, and the corresponding relation between Custom Number and the IM sign is set.With phone operation system being set below is example, the process prescription that the user is provided with the corresponding relation between Custom Number and the IM sign is as follows: the user by the telephone terminal input with corresponding access code is set, can the corresponding relation of Custom Number between identifying with IM be set according to prompting then.The system of setting can at first carry out authentication to the user, if the user by authentication, then allows the user that the corresponding relation of Custom Number between identifying with IM is set; If the user is not by authentication, then refusing user's is provided with the corresponding relation between Custom Number and the IM sign.The system that is provided with also can generate automatically with IM and identify corresponding Custom Number, and notifies the user.The user can make amendment to the corresponding relation between Custom Number and the IM sign by system is set, also can increase or reset corresponding relation between Custom Number and the IM sign by system is set, also can be by Custom Number that system-kill has been provided with and the IM corresponding relation between identifying is set.
In addition, the client and server that the user also can provide by operator, realize Custom Number and IM identify between the setting of corresponding relation.The user is by the corresponding relation between client input Custom Number and the IM sign, before this can be at first authentication by client, client can will be sent to server based on the corresponding relation between Custom Number under the user ID and the IM sign by IP network, be stored by server.The user can make amendment to the corresponding relation between Custom Number and the IM sign by client, also can increase or reset the corresponding relation of Custom Number between identifying with IM by client, also Custom Number that can be provided with by client deletion and the corresponding relation between the IM, corresponding change all can offer server by client and store.
The above Custom Number is not limited in digital number, also can be numbers such as symbol, letter.Under the prerequisite that does not influence calling, in Custom Number and the corresponding relation between the IM under the user ID, an IM sign can be corresponding with a plurality of Custom Numbers.Corresponding relation between Custom Number and the IM sign can be stored in the network entities such as soft switch, intelligent network, application server.Above-described IM sign can comprise IM service provider sign and IM user ID.
Fig. 3 shows calling Internet device process schematic diagram, as shown in Figure 3, store the Custom Number of calling terminal user setting and the corresponding relation between the IM sign in the network in advance, this IM sign comprises IM service provider sign and IM user ID, and the implementation procedure of calling Internet device may further comprise the steps:
Step 303: after Tandem Gateway is received call request, transmit this call request to soft switch.After Tandem Gateway is received the ISUP signaling, trigger the related service of calling Internet device according to service access code, the relevant information of the Custom Number of calling identification and calling is reported to soft switch, and the control of soft switch is accepted in current calling, finishes next step operation according to the indication of soft switch.Soft switch possesses the ability that control, signaling and protocol processes and basic service provide of calling out, also can by with the cooperating of application server, finally provide diversified value-added service to the user.
Step 304: after the relevant information of Custom Number of calling identification and calling is received in soft switch, obtain based under this calling identification, with the corresponding IM sign of the Custom Number of this calling, this IM sign comprises IM service provider sign and IM user ID, soft switch is found corresponding IM server according to IM service provider sign, sends the call request that carries the IM user ID to this IM server then.Can adopt Session Initiation Protocol or other agreements alternately between soft switch and the IM server, as XMPP (Extensible Messaging and Presence Protocol), the SIMPLE (SIP for InstantMessaging and Presence Leveraging Extensions) etc. of ietf definition.
Soft switch can according to self storage based on the corresponding relation between the Custom Number under the user ID and the IM sign, the corresponding IM of the Custom Number that obtains and call out identifies; Also can be by identifying with the corresponding IM of obtaining alternately of other network entities, the Custom Number of calling identification and calling is provided to application server as soft switch, application server is according to the corresponding relation between the identifying based on the Custom Number under the user ID and IM of self storage, the corresponding IM sign of the Custom Number of searching and calling out sends this IM sign to soft switch then.
The concrete form of corresponding relation can be relational database between Custom Number of storing in the network and the IM sign, sets up tables of data in relational database, comprises four fields: calling identification, Custom Number, IM service provider sign, IM user ID.Can calling identification in this relational database, Custom Number sets up unique index, to accelerate search speed.When searching, in relational database, search for, find out corresponding IM service provider's sign and IM user ID according to calling identification and Custom Number.
The user can directly be provided with the corresponding relation between Custom Number and IM service provider sign, the IM user ID, as the IM user ID is sip.jake.com.tom@jake.com, soft switch can be to the domain name jake.com corresponding address of name server (DNS) inquiry with IM service provider sign, to obtain the IP address of IM server.Like this, need not in soft switch the IM server to be registered in advance, the IM server of any DNS of having can both driedly obtain corresponding IP address.Also can in soft switch, set in advance the corresponding relation between IM service provider sign and the IP address, by the extremely corresponding IM server of this IP addressing of address.For example, the corresponding relation between storage IM service provider sign and the IP address in soft switch in advance, as MSN, 123.123.112.123, soft switch just can according to the sensible corresponding IP addressing of address of IM service mark IM server extremely accordingly.Like this, when the corresponding relation that is provided with between IM service provider sign and the IP address, some other configuration datas can also be set, as communication protocol of communicating between soft switch and the IM server etc., as other agreements such as the Extended Protocol-SIMPLE agreement of SIP or XMPP agreements.It is more flexible that network is connected, and the user is provided with simply, need not to import protocol information, and only need to select IM service provider sign in tabulation, and operator can control the IM operator of calling in addition.
After step 305～step 306:IM server is received call request, judge according to the IM user ID whether corresponding internet device is current online, if internet device is current online, then transmit this call request to internet device, after internet device is replied, set up internet device and be connected with IP between the Tandem Gateway, as User Datagram Protoco (UDP) (UDP) connect, transmission control protocol (TCP) connects etc., realizes the transmission of voice.If internet device is current not online, then notify the current calling of soft switch to continue, the current calling of soft switch notice Tandem Gateway can't continue, and the current calling of Tandem Gateway notice calling terminal can't continue.
Fig. 4 shows the calling Internet device message flow chart, as shown in Figure 4, store the Custom Number of calling terminal user setting and the corresponding relation between the IM sign in the network in advance, this IM sign comprises IM service provider sign and IM user ID, and the message flow of calling Internet device may further comprise the steps:
Step 401～step 405: Tandem Gateway is received after the call request that internet device is initiated, according to the service access code that carries in the call request, or directly according to the Custom Number of calling out, call request is forwarded to soft switch, and promptly Tandem Gateway sends the initial address message (IAM) of the Custom Number that carries calling identification and calling to soft switch.After IAM is received in soft switch, obtain based under this calling identification, with the corresponding IM sign of the Custom Number of this calling, the IP address that obtains corresponding IM server according to this IM sign sends the INVITE that carries the IM sign to the IM server then.After the IM server is received INVITE, judge according to the IM sign whether corresponding internet device is current online, if then send INVITE, and return 100 responses, and continue execution in step 406 to soft switch to internet device; If not, then notify soft switch to finish current call flow, soft switch notice Tandem Gateway finishes current call flow, and the current calling of Tandem Gateway notice calling terminal can't continue.
Step 406～step 414: after internet device is received INVITE, send 180 responses to the IM server; After the IM server is received 180 responses, send 180 responses to soft switch; Soft switch sends Address Complete Message (ACM) to Tandem Gateway after receiving 180 responses.Internet device sends 200 responses to the IM server; After the IM server is received 200 responses, send 200 responses to soft switch; Soft switch sends response message (ANM) to Tandem Gateway after receiving 200 responses.Soft switch sends ACK message to the IM server, and the IM server sends ACK message to internet device.Set up internet device and be connected, converse with calling terminal with IP between the Tandem Gateway.
Step 415～step 420: calling terminal discharges current calling, and Tandem Gateway sends call release message (REL) to soft switch; After REL is received in soft switch, send Release complete (RLC) to Tandem Gateway.Soft switch sends BYE message to the IM server, after the IM server is received BYE message, send BYE message to internet device, after internet device is received BYE message, send 200 responses to the IM server, after the IM server is received 200 responses, send 200 responses to soft switch, so far whole calling procedure finishes.
Above-described Tandem Gateway comprises the function of SGW, and in the practical application, Tandem Gateway and SGW also can set up separately.SGW is by gateway control protocol (H.248) control Tandem Gateway.The above is the business that soft switch provides calling Internet device, this business also can be cooperated with application server by soft switch to be finished, promptly should business by application server realizing, application server can be controlled the soft switch replay call by Session Initiation Protocol, with can being finished by application server alternately of IM server.
Internet device has only an IP address based on public network mostly, and this IP address is globally unique.But have some users to adopt the mode of internal network to surf the Net, as the NAT address spaces, in this case, can provide a gateway device, audio call need pass through this gateway device, promptly can not directly obtain the IP address of internet device.When setting up internet device and IP between the Tandem Gateway being connected, will need to set up IP indirectly by this gateway device and connect, no longer be directly to set up IP to connect.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
