Description

Method, device and system for implementing attendant insertion call in switchboard business

The present invention relates to a centralized user switch (Central Exchange, Centrex) service technology in intelligent network communication, and more particularly to a method, device and system for implementing an attendant to insert a call in a switchboard service. Background technique

The Centrex service divides some users into a basic user group on the switch of the telephone office or the telecommunication company, and provides the user group with various functions of the user-specific switch, and also provides some unique service functions. However, there is no actual private switch in this user group. All the hardware required for the Centrex service is in the switch of the telephone office or the telecommunication company. The internal and external exchange of users is concentrated in the switch of the telephone office or the telecommunication company. Therefore, Centrex is also known as a virtual subscriber switch. The Centrex business network is flexible and can easily increase or decrease capacity. It is widely used in group users such as factories and mines, universities, government agencies, group companies, hotels, hospitals, financial institutions.

The number corresponding to the switchboard of the group user using the Centrex service is called the Main Number, also called the switchboard number. The Centrex business includes extension and switchboard services, and the switchboard business includes the inbound and outbound processes. The incoming call process means that the users inside and outside the group dial the switchboard number to trigger the switchboard service. The service chooses to call one of the attendants according to a certain policy. After the attendant answers the call, the service bridges the call between the caller and the attendant. The outgoing call process, that is, the caller calls out, triggers the switchboard service, and the service first calls the attendant. After the attendant picks up the phone, the caller calls the called party. The called party's caller ID number is the switchboard number. After the called party picks up the phone, the service will call the attendant and the called party. User bridges the call.

Users in the group can be traditional users such as the public switched telephone network (Public Switched) Telephone Network, PSTN), Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) users, or new users such as soft terminals, integrated access devices (Integrated) Access Device, IAD), Internet Protocol (IP) phone and video terminal users.

Referring to FIG. 1, the existing system for implementing the Centrex service includes: an operator WEB interface, a web server (Web Server, WS), a Centrex service application server (AS), and a media resource server (Media Resource Server, MRS) and User Equipment (UE). The system has the function of Click To Dial (CTD) service. The topology of the IP Multimedia Subsystem (IMS) or the Next Generation Network (NGN) is hidden in Figure 1. In implementation, the AS, MRS, and UE are connected to the IMS or NGN network.

The following describes the functions of the various parts of the system that implement the Centrex business.

The operator WEB interface is a device provided to the operator for initiating a call or performing call control, such as a personal computer (PC), a third generation mobile communication technology (Ord-Generation, 3G) terminal, and the like.

WS is used to provide Hyper Text Transfer Protocol (HTTP) service functions such as user login, call number filling, call control and information display interface.

The AS is used to provide the functions of the underlying switchboard services, such as call control, status report, and bill generation.

MRS is used to provide voice media, and can be used as a Media Server (MS). The UE is used for the call of the user in the group, and the specific physical device may be: a fixed telephone, a mobile phone or a video terminal.

The following describes the protocols used between the various parts of the system that implement the Centrex service. The operator WEB interface and the WS are HTTP service calls, using the HTTP protocol. WS and AS are inter-server communication, using application layer protocol. The application layer protocol can use Extensible Markup Language (XML) according to specific needs. If the application layer protocol is not used, the transmission control protocol can be customized. Transmission Control Protocol, TCP) message.

The call is made between the AS and the MRS or the UE through the media negotiation protocol. The AS and the UE use the Session Initiation Protocol (SIP) to communicate with each other through the IMS or the NGN. The SIP or media gateway control protocol is usually used between the AS and the MRS. (Media Gateway Control Protocol, MGCP), depending on the type of protocol supported by the MRS.

The media negotiation is performed between the UE and the MRS according to the codec format, the transceiver port, the bandwidth transmission rate, and the like of the media packet at the time of the call, and the media stream is transmitted.

The following describes the flow of users in the existing operator call group. In this example, the attendant calls user A in the group.

Step 1. The attendant logs in to the WEB interface, enters the primary number, clicks the call, and places a call request. For the case where the telephone terminal used by the operator is a soft terminal, for example, the telephone terminal is an ActiveX control embedded in the operator WEB interface, and the operator can log in to the WEB interface to query the switchboard number. Therefore, the attendant can select the switchboard number without entering the switchboard number.

Step 2: The AS receives the call request, sends a response to the request to the WS, and the operator's WEB interface displays the prompt information in real time: The call is being processed.

Step 3, AS calls the attendant H.

Step 4: The AS reports the response of the attendant H to the WS, and the WS control WEB interface displays the prompt information, such as ringing, not online, busy, off-hook, and the like. If the switchboard is not off-hook, go to step 5. If the switchboard goes off-hook, go to step 6.

Step 5: The WS control WEB interface displays the prompt message: The attendant H does not pick up the phone, the call fails, and the process ends.

Step 6. The AS calls the telephone number of the user A in the group. In step 7, the AS reports the response of the user A to the WS, and the WS controls the WEB interface column to display the prompt information in real time, such as ringing, not online, busy, off-hook, and the like. If the temporary response of the user A is ringing, the process proceeds to step 8; if the temporary response of the user A is no ringing, the process proceeds to step 9.

Step 8. The AS plays the ringback tone to the attendant H, and the ringtone carries the short service prompt information. Step 9, determining the final response of user A. If user A finally responds by going off-hook, go to step 10; if user A's final response is not off-hook, go to step 12; if user A's final response is busy, then Go to step 14.

Step 10: The AS stops playing the ring back tone to the operator H.

Step 11: The AS bridges the operator H with the user A, and the two parties can talk, and the process ends. Step 12, WS control WEB display failure prompt message: The called party does not go off-hook, the call fails. Step 13, the AS gives the attendant H a failure prompt tone: The called party does not go off-hook, the call fails, and the process ends.

Step 14, WS control WEB display failure prompt message: The called party is busy, the call fails.

Step 15. The AS gives the attendant H a failure prompt tone: The called party is busy, the call fails, and the process ends.

At the same time, the operator WEB interface displays the status of the current call, such as: the phone number and name of both parties to the call, the call status (such as: called ringing, called response, called hang up, etc.), incoming or outgoing messages (such as: Call time, call duration, calling and called number, etc.) and the avatar used by both parties.

As described above, in the prior art, if the attendant has an important notification to inform the user A in the group, but the user A is talking to the user B in the same group, at this time, the operator cannot connect to the user A's phone, important. The notification cannot be communicated to User A in time. Summary of the invention

The first embodiment of the method for implementing an attendant insertion call in the switchboard service will be described below. As shown in FIG. 4, in this embodiment, the method includes:

Step 401: Issue an outgoing call request of the calling operator and the called user.

Specifically, the attendant logs in to the operator WEB interface, enters or selects the primary number, and then clicks on the call to place a call request.

Step 402: When the attendant goes off-hook and the final response of the called user is busy, an insert call request is sent.

Specifically, when the attendant goes off-hook and the final response of the called user is busy, the Skype Control Attendant WEB interface's Insert Call button is available. If the attendant clicks the Insert Call button within the set time (for example, 10 seconds), an insert call request is issued; if the attendant does not click the Insert button within the set time, the current process is ended.

Step 403: Determine whether the called user satisfies the condition for inserting a call, and if the condition for inserting the call is met, enter the step of joining the three-party call conference, that is, step 404; if the condition for inserting the call is not satisfied, the current process is ended;

The condition for the insertion of the call is: the called user is only talking to the opposite user of the non-switchboard, and the called user is a user within the group.

Step 404: Add the attendant, the called user, and the peer user who is talking to the called user to the three-party conference according to the request for inserting the call, so as to implement the call between the operator and the called user.

Specifically, the three-party conference resource is applied to the MRS according to the request for inserting the call, and the attendant, the called user, and the peer user who is talking to the called user are respectively added to the three-party conference. A second embodiment of a method for implementing an attendant to insert a call in the switchboard service of the present invention will be described in detail below with reference to FIG.

Step F1, the operator H logs in to the operator WEB interface, enters or selects the called user A and clicks on the call.

Step F2, the AS receives the call request, sends a response to the request to the WS, and the WS control attendant displays the prompt information in real time on the WEB interface: During call processing.

Step F3, AS calls the attendant H.

Step F4, the AS reports the response of the attendant H to the WS, and the WS controls the operator WEB interface to display prompt information, such as ringing, not online, busy, off-hook, etc. in real time.

Step J1, the AS determines whether the final response of the operator H is off-hook. If the final response of the operator H is off-hook, step F6 is performed; if the final response of the attendant H is not off-hook, step F5 is performed.

Step F5, the WS is based on the status information that the attendant H reported by the AS is not responding to the off-hook. The WEB displays the failure prompt message: The attendant H does not go off-hook, the call fails, and the process ends.

Step F6, the AS calls the called number A.

Step F7, the AS reports the response of the called number A to the WS, and the WS controls the operator to display the prompt information in the WEB interface column, such as ringing, not online, busy, off-hook, and the like.

Step J2, the AS determines whether the temporary response of A is ringing. If the temporary response of A is ringing, step F8 is performed; if the temporary response of A is no ringing, step J3 is performed.

Step F8, the AS plays the ring back tone to the operator H, carries the short service prompt information, and then performs step J3.

Step J3, the AS determines whether the final response of A is not off-hook. If the final response of A is not off-hook, step J4 is performed; if the final response of A is off-hook, step F11 is performed.

In step J4, the AS determines whether the final response of A is busy. If the final response of A is busy, step F13 is performed. If the final response of A is not busy, go to step F9. In step F9, the WS controls the WEB display failure prompt message according to the status information of the A that is reported by the AS as being not busy: the called party does not go off-hook, and the call fails.

Step F10, the AS gives the attendant H a failure prompt tone: The called party does not go off-hook, the call fails, and the process ends.

Step Fll, the AS stops playing the ring back tone to the operator H.

Step F12, the AS bridges the operator H with the called party A, and the HA enters the two parties to talk, and the process ends.

Step F13, the WS controls the WEB interface insertion button to become available according to the status information of the A reported by the AS as the busy status information.

Step J5, WS determines whether the operator H clicks the insert button within the set time (for example, 10 seconds), if the operator H clicks the insert button within the set time, step F14 is performed; if the attendant H does not click the insert within the set time Button, go to step F9.

Step F14, the WS sends an insert call request to the AS.

Step J6: The AS determines whether the called user A satisfies the condition of the inserted call by querying the internal information. If the called user A satisfies the condition for inserting the call, step F16 is performed; if the called user A does not satisfy the condition for inserting the call, step F15 is performed. Conditions that are not satisfied are: A is not a group user, A is making two calls (that is, talking to two users at the same time), A is talking to other attendants at the switchboard, and A is in a three-way call or conference.

Step F15: The AS responds to the WS by inserting a call request: the called user does not satisfy the inserted condition, and the insertion operation fails, and step F9 is performed.

Step F16, the AS responds to the WS by inserting a call request: The insert call request is being processed. Step F17, the AS applies to the MRS for the three-party conference resource.

In step F18, the AS joins the attendant H, the called user A, and the peer user B respectively, and controls the attendant H, the called user A, and the opposite user B to be audible, the attendant H, the called user A, and The peer user B enters the three-party call state. In step F19, the AS responds to the WS by inserting a call request: the insertion is successful, and the process ends.

As can be seen from the above, the above technical solution can be used to enable the attendant to connect to the user of the group who is talking to other users.

A third embodiment of a method for implementing an attendant insertion call in the switchboard service of the present invention will be described below with reference to FIG. In this example, the attendant is H, the called user is A, and A is talking to the peer user B. A is the intra-group user and B is the non-operator. In addition, in this example, the INVITE request sent by the AS to H carries the media information.

Step 601: The WS initiates an outgoing call request to the AS, and carries the call information including the number of the H and the number of the A.

Step 602, the AS returns a call response to the WS: accepts the request, and the call is being processed. Step 603: The AS sends an INVITE request to the H.

Step 604, H ringing, H returns 180 180 ringing temporary response to AS, to confirm whether 180 is reliable, AS can return PRACK temporary confirmation to H, and H replies 200 OK (PRACK) to AS, then proves that 180 is reliable.

In step 605, the AS notifies the WS of the status: H ringing.

Step 606, H picks up the phone, and H replies with a 200 OK (INVITE) response to the AS, and carries its own media information.

In step 607, the AS notifies the WS of the status: H picks up the phone.

Step 608: The AS sends an INVITE request to A.

In step 609, A replies to the AS with a final response of 486 Busy.

In step 610, the AS notifies the WS of the status: The called A is busy.

Step 611: The AS sends an ACK acknowledgement message to A.

Step 612, the WS according to the state notified by the AS to the WS "called A busy" control WEB interface insert button is available, click the insert button within a certain time, the WS sends an insert request to the AS, carrying relevant information: H and A number, etc. . In step 613, the AS returns a call response to the WS: accepts the request and starts processing the insertion.

Step 614: The AS determines the condition that the called user A satisfies the inserted call by querying the internal information, and applies for the three-party conference resource to the MRS. The AS sends an INVITE message to the MRS and carries the media information of the H. AS wants to join H to the conference.

Step 615, the MRS returns a 200 OK response to the AS, and carries its own media information. Step 616: The AS sends an ACK acknowledgement message to the MRS.

Step 617: The AS sends an ACK acknowledgement message to the H, and carries the media information of the MRS. Step 618, the AS sends an INFO notification message to the MRS, and controls the MRS to mix the H.

In step 619, the MRS returns a 200 OK ( INFO ) response to the AS.

Step 620: The AS returns a call response to the WS: H joins the conference successfully.

Step 621: The AS sends a REINVITE message to UE A.

Step 622: UE A returns a 200 OK response to the AS, and carries its own media information.

Step 623: The AS sends an INVITE message to the MRS, and carries the media information of the UE A. Step 624: The MRS returns a 200 OK response to the AS and carries its own media information. Step 625: The AS sends an ACK acknowledgement message to the MRS.

Step 626, the AS sends an ACK acknowledgement message to the UE A, and carries the media information of the MRS. Step 627, the AS sends an INFO notification message to the MRS, and controls the MRS to mix A.

In step 628, the MRS returns a 200 OK ( INFO ) response to the AS.

Step 629, the AS returns a call response to the WS: User A joins the conference successfully.

Step 630: The AS sends a REINVITE message to the UE B.

Step 631: UE B returns a 200 OK response to the AS, and carries its own media information.

Step 632: The AS sends an INVITE message to the MRS, and carries the media information of the B. In step 633, the MRS returns a 200 OK response to the AS and carries its own media information. In step 634, the AS sends an ACK acknowledgement message to the MRS.

Step 635: The AS sends an ACK acknowledgement message to the UE B, and carries the media information of the MRS. Step 636, the AS sends an INFO notification message to the MRS, and controls the MRS to mix B: audible.

In step 637, the MRS returns a 200 OK ( INFO ) response to the AS.

Step 638, the AS returns a call response to the WS: B joins the conference successfully.

Step 639, the AS returns a call response to the WS: H inserts the call successfully.

Thus, the operator can talk to the called user A who is in a call with the opposite user B. Next, a fourth embodiment of a method for implementing an attendant insertion call in the switchboard service of the present invention will be described with reference to FIG. In this example, the attendant is H, the called user is A, and A is talking to the peer user B. A is the intra-group user and B is the non-operator. In addition, in this example, the AS sends to H.

The INVITE request does not have media information.

Step 701: The WS initiates an outgoing call request to the AS, and carries the call information including the number of H and the number of A.

Step 702, the AS returns a call response to the WS: accepts the request, and the call is being processed. Step 703: The AS sends an INVITE request to the H.

Step 704: UE H rings, and H returns a 180 ringing temporary response to the AS, and carries its own media information.

Step 705, the AS notifies the WS of the status: H ringing.

Step 706: The AS sends a PRACK message to the UE H, and carries the AS media information.

Step 707: UE H returns a 200 OK (PRACK) response to the AS.

Step 708: UE H picks up the phone, and UE H replies with a 200 OK (INVITE) response to the AS. In step 709, the AS notifies the WS of the status: H picks up the phone.

Step 710: The AS sends an ACK acknowledgement message to the UE H.

Step 711: The AS sends an INVITE request to UE A. In step 712, A replies to the AS with a 486 Busy final response.

Step 713, the AS notifies the WS of the status: The called A is busy.

Step 714, the AS sends an ACK acknowledgement message to A.

Step 715, the WS control WEB interface insertion button is available, and the insertion button is clicked within a certain time, and the WS sends an insertion request to the AS, carrying relevant information: H and A numbers, and the like.

In step 716, the AS returns a call response to the WS: accepts the request and begins processing the insertion.

In step 724, the MRS returns a 200 OK ( INFO ) response to the AS.

Step 725: The AS returns a call response to the WS: H joins the conference successfully.

Step 726: The AS sends a REINVITE message to UE A.

In step 727, UE A returns a 200 OK response to the AS and carries its own media information.

Step 728: The AS sends an INVITE message to the MRS, and carries the media information of the A. In step 729, the MRS returns a 200 OK response to the AS and carries its own media information. In step 730, the AS sends an ACK acknowledgement message to the MRS.

Step 731: The AS sends an ACK acknowledgement message to the UE A, and carries the media information of the MRS. Step 732: The AS sends an INFO notification message to the MRS, and controls the MRS to mix A: It can be heard.

In step 733, the MRS returns a 200 OK ( INFO ) response to the AS.

Step 734, the AS returns a call response to the WS: User A joins the conference successfully.

Step 735: The AS sends a REINVITE message to the UE B.

Step 736: UE B returns a 200 OK response to the AS, and carries its own media information.

Step 737: The AS sends an INVITE message to the MRS, and carries the media information of the B. Step 738, the MRS returns a 200 OK response to the AS, and carries its own media information. In step 739, the AS sends an ACK acknowledgement message to the MRS.

Step 740: The AS sends an ACK acknowledgement message to the UE B, and carries the media information of the MRS. Step 741: The AS sends an INFO notification message to the MRS, and controls the MRS to mix B: audible.

In step 742, the MRS returns a 200 OK ( INFO ) response to the AS.

Step 743, the AS returns a call response to the WS: B joins the conference successfully.

Step 744, the AS returns a call response to the WS: H inserts the call successfully.

Thus, the operator can talk to the called user A who is in a call with the opposite user B. The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
