Conventional directory assistance systems include voice relays, PBXs, directory assistance platforms, and voice agents. After dialing the directory number, the user routes the call through the communication network, and then the call is transferred to the voice seat by the PBX. The voice seat performs data record search on the directory assistance platform according to the name and the user information provided by the user. Once the records match, the agent will broadcast the corresponding number to the user. Or the telephone traffic can be relayed to the communication network through the PBX and the voice according to the needs of the user, and then the communication network completes the connection to the final checking and transferring user.

Detailed Description
The invention will be further illustrated with reference to specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
Referring to fig. 1, the present invention discloses an intelligent number forwarding system based on user status. As shown in the figure: a preferred embodiment of the system comprises an IP multimedia subsystem 100, a user status presentation server 200, an intelligent search platform 300 and an operator IT system 400.
The IP multimedia subsystem is a system for supporting real-time, customizable multimedia services based on SIP signaling, which constitutes the IMS core network for the communication services. The IP multimedia subsystem 100 comprises a home subscriber server 101, a call session control function network element 102 and a session border controller 103. The home subscriber server 101 is configured to record various subscription information of the subscriber in the IP multimedia subsystem 100. The call session control network element 102 is used to process various call related signaling in the IP multimedia subsystem 100, and the session border controller 103 is used to access the end user 500 to the IP multimedia subsystem 100. The operator IT system 400 is composed of a service acceptance system and a user accounting system. The service acceptance system receives the subscription request of the user, generates subscription information, stores the subscription information in the user accounting system, and then informs the home subscriber server 101, and the home subscriber server 101 generates service trigger data according to the user subscription information and synchronizes the service trigger data to the call session control function network element 102. The service triggering data comprises triggering conditions and addresses of application servers which process the messages intelligently after triggering. In the intelligent number forwarding service, the triggering condition comprises a calling number, a called number and a protocol message type. The application server that triggers post-processing of the message is the user state presentation application server 200. That is, after the call session control function network element 102 receives the service trigger data, after the registration signaling and the call signaling of the user who signs the intelligent number forwarding service are transmitted to the call session control function network element 102 through the session border controller 103, the call session control function network element 102 converts the signaling information into user state information and transmits the user state information to the user state presentation application server 200, so that the intelligent number forwarding service is enabled to be effective.
When the subscriber is in the 4G or 5G network, the user state presence service server 200 converts the signaling information obtained from the call session control function network element 102 into user state information of the subscriber, and obtains location information through the location server 201. When the subscriber falls back to the 2G or 3G network, the subscriber status presence service server 200 will obtain the subscriber status information of the subscriber from the mobile switching center 203 and the location information through the gateway mobile location center 202. Then, the user status presence service server 200 packages the user status information and the location information in the JASON format, and synchronizes to the intelligent search platform 300 in real time through the user status interface 700 based on the HTTP protocol.
When a directory enquiry user initiates a directory enquiry request, the intelligent lookup platform 300 firstly matches the target user manually through a human agent 301 or automatically by an intelligent engine 302 supporting real-time speech recognition technology. If the target user is a subscriber of the intelligent number forwarding service, different scene modes are further determined according to the user state information and the position information provided by the user state presentation service server 200, and then the corresponding user number is fed back to the directory enquiry user in a specified response mode (broadcast to the directory enquiry user or forwarded to the directory enquiry user) according to the scene modes. In the forwarding mode, the forwarded destination number includes a number to be forwarded to a voice mailbox, an intelligent robot, or a subscriber.
The terminal application 600 is an application program provided by a subscriber and running on an intelligent terminal of the subscriber. The subscriber can autonomously set the user status information of the subscriber, such as user login, user idle, user busy, user offline, and user-defined status, through the terminal application 600. In the actual forwarding and searching service, the operator determines whether the state set by the user is the preferred state or the actual state of the user is the preferred state by configuration. The subscriber can also set a response mode and a subscriber number in each scene mode through 600. For example, a specific number of a fixed telephone or a relative number is designated to be switched to when the user is busy, a specific audio-video content is designated to be played by the intelligent robot when the user is offline, and the like.
Referring to fig. 2, a process of converting the signaling information obtained by the network element 102 according to the call session control function into the user state information of the subscriber by the user state presence service server 200 is shown.
After the subscriber completes the intelligent number searching and transferring service, the subscriber opens the general subscriber state presenting function and simultaneously makes the calling and called IFC subscription in the network. Thereafter, when the subscriber starts the VOLTE function to access the 4G/5G network, the terminal user 500 first sends a registration (Register) signaling to the call session control function unit 102, and the call session control function unit 102 forwards the registration (Register) signaling to the user state presentation application server 200. After receiving the signaling, the user state presentation application server 200 updates the user state information of the subscriber to user login and user idle. (step S101)
When the terminal user 500 initiates a call, the call session control unit 102 sends a corresponding call initiation signaling (inite) to the user status presentation application server 200, and after the called user answers (200OK), the user status presentation application server 200 updates the user status information of the subscriber to user busy. (step S101)
When the call is over, the user state presence application server 200 will again modify the user state information to idle after the on-hook signaling (BYE) is forwarded to the user state presence application server 200 again. (step S103)
When the terminal user 500 is called, the user status presenting application server 200 sets the user status information as user busy after receiving a 200OK response to the origination signaling (inite). (step S104)
After the call is finished, the user state presenting application server 200 receives a hang-up signaling (BYE), and sets the user state information as user idle. (step S105)
If the user is called and the call is failed, the user status presentation application server 200 determines whether the user is actively hung up or is disconnected or busy due to network reasons through the returned error message (4xx) and the corresponding error return value, and updates the user status. For example, if the user status presence application server 200 receives 486BUSY signaling, it is considered that the user is actively hanging up. (step S106) if the user status presentation application server 200 receives 408TIMEOUT signaling, it is deemed that the user is not reachable. (step S107)
After receiving the logout information forwarded by the call session control unit 102, the user status presentation application server 200 will determine whether the terminal user 500 is passively offline or actively powered off when time out according to the historical signaling information and update the user status information to be offline. (step S108)
While updating the user state information, the user state presentation application server 200 updates the user geographical location data in time according to the PANI parameter in the call signaling parameter.
Referring to fig. 3, the present invention further provides an intelligent number forwarding method based on user status, the implementation process of a preferred embodiment of the present invention includes the steps of:
step S201, the directory enquiry user initiates voice directory enquiry to the intelligent number transferring system.
The intelligent number checking and forwarding system acquires the information of the checked and forwarded user through an intelligent engine or a manual agent, for example, the information is information of a certain business company;
step S202, judging whether the searched user is a signed user of the intelligent number searching and forwarding service. If the signed user is not the subscriber, the process goes to step S203, otherwise, the process goes to the intelligent forwarding process from step S204.
Step S203, entering a traditional common checking and transferring process, and exiting the checking and transferring process after the number checking is finished.
Step S204, the user state information of the signing user is obtained from the user state presentation service server, and whether the user state of the corresponding user number is the user login is judged firstly. If the user number is not logged in (it may be off or a fixed telephone fault), step S205 is entered, otherwise step S206 is entered.
And S205, entering an intelligent robot response scene, switching on the intelligent response robot, and finishing the intelligent checking and transferring process after playing the audio and video. The audio and video played by the intelligent machine can be set by a signed user through a terminal application, and can also be default audio and video.
Step S206, determining whether the user status information of the subscriber number corresponding to the subscriber is idle. If not, the user is in an idle state (logged on and the status is busy, i.e. currently unable to answer), step S207 is entered, otherwise step S208 is entered.
And step S207, entering a voice mailbox scene, connecting the voice mailbox, and receiving a message left by the user. The prompt message of the voice mailbox can be set by the subscriber through the terminal application, or can be the default prompt message. And after the voice mailbox interaction is finished, the intelligent switching process is finished.
Step S208, judging whether the subscriber presets the custom state. If the custom state is not set, the process proceeds to step S209, otherwise, the process proceeds to step S210.
Step S209, according to the response mode set by the subscriber through the terminal application, broadcasts the subscriber number (i.e., the main number) corresponding to the subscriber to the directory enquiry user, or switches the call to the subscriber number. And finishing the intelligent searching process.
Step S210, determining whether the subscriber preset a geographic information determination requirement. If the geographic information judgment requirement is not set, the process proceeds to step S211, otherwise, the process proceeds to step S212.
Step S211, according to the response mode set by the subscriber through the terminal application, the preset telephone numbers set by the subscriber in different states are broadcasted to the directory enquiry user, or the call is switched to the preset telephone numbers, and then the intelligent search process is ended. The subscriber sets preset numbers in different states through terminal application, for example, the subscriber provides a fixed telephone number when busy, the subscriber provides another mobile phone number when offline, and the like.
Step S212, if the geographic information judgment requirement exists, the position information of the signing user is obtained from the user state presentation service server, and the audio and video which is preset by the signing user and corresponds to the position information is played. For example, different promotional media for defenses are played according to different geographical locations.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
