Description

Method for realizing CRBT service in No.1 communication service and No.1 service

Technical field

The present invention relates to the field of intelligent network communication under the network of NGN (Next Generation Network) and IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), as well as the one-number communication and color ring tone service, and particularly relates to a one-number service The method for realizing the CRBT service and the one-number service server.

Background technique

The existing NEs that implement the No. 1 service are shown in Figure 1. The description is as follows:

User Equipment (UE): A device that initiates a call, answers a call, and performs other call operations, such as a C-network or G-network handset, a PSTN (Public Switched Telephone Network) terminal, an IMS terminal, etc.

Application Server (AS): Provides the underlying service capabilities, such as: call control, status reporting, and bill generation.

Media Resource Server (MRS): Provides voice media capabilities, usually Media Server (MS), such as playback, playback, and conference mixing.

The protocols used in specific NEs are as follows:

The AS negotiates with the MRS or the AS for the call negotiation. The AS and the UE communicate with each other through the core network using the SIP (Session Initiation Protocol) protocol. The AS and the MRS usually use the SIP protocol or the MGCP (Media Gateway Control Protocol). The protocol depends on the type of protocol supported by the MRS.

The UE and the MRS are used for media stream transmission, and the information such as the codec format, the transceiver port, and the bandwidth transmission rate of the UE and the MRS specific media packet are determined according to media negotiation between the terminal and the MRS at the time of the call.

Note: In Figure 1, it is only a schematic diagram, which hides the topology of the IMS network or the NGN network. In actual implementation, the AS, MRS and UE are connected or anchored to the IMS network or the NGN network. of.

The so-called number one service means that the user sets a mobile number or IMS or NGN (IMS/NGN) terminal number as the main number of the service, and can set one or more mobile numbers or IMS/NGN terminal numbers to The binding number of the call and the binding number when calling (hereinafter referred to as the binding number is the secondary number), the caller ID is the main number when the call is made, and the CS number of the main number and the secondary number are the same or the same when the call is made. Domain and IMS/NGN domain converged services. The user can set the ringing mode of the receiving call for the primary number. When the primary number is used as the called party, the primary number terminal and all the secondary number terminals can be simultaneously ringed or sequentially ringed according to the user's setting (the order can be user-defined) Specify).

The user of No.1 can set the main number as the ringing mode when the called party is called according to the needs: At the same time, when the incoming call, the service rings the user's main number and all the associated numbers at the same time, the actual use of the same mode. The situation is shown in Figure 2-1. Figure 3-1 shows the flow chart of the same number. The user A calls the user B, the number connects the AS to determine that the user B is the same, and calls the primary number user B and the assistant. Numbers Cl, C2, etc.; After receiving the first 180Ring, the No.1 AS sends a 180Ring temporary response to the calling user A whether it is sent by the primary number or the secondary number; the first one receives the first 200. After the OK off-hook event, whether it is the primary number or the secondary number, it is bridged with the calling user A, and other users are released. The calling number is displayed as the case may be. If there is a terminal answering, the other terminals stop ringing; when the incoming call is made, the service rings in accordance with the ringing sequence set by the user, until one terminal answers or the last terminal rings timeout. The actual use of the mode is shown in Figure 2-2. The flow chart of the first pass is shown in Figure 3-2. User A calls user B, and the number AS determines that user B is moving, and calls the primary number in sequence. User B and the secondary numbers Cl, C2, etc., the first one receives the first 180Ring, and whether the primary number or the secondary number is sent, the calling user A replies with a 180Ring temporary response, and the primary number and the secondary number are composed. If the number in the sequence list does not go off-hook within a certain period of time, the AS continues the next number in the call sequence list; the first-pass AS receives the first 200 OK off-hook event, whether it is the primary number or the secondary number. They are bridged with the calling user A and no longer call other users. . The calling number is displayed as the case may be.

The so-called ring tones are the abbreviation of "Coloring Ring Back Tone", which is a special sound effect (music, song, story) set by the called customer to call other calling customers. The business of the ringback tone of the plot, the character dialogue). Ring back tone in IMS/NGN domain The flow chart is shown in Figure 4. User A calls User B and arrives at CRBT AS. The CRBT AS receives the 180Ring temporary response from User B. Then, it applies the playback resource to the MRS, and plays the CRBT tone that User B subscribes to. After B picks up the phone, the CRBT AS stops playing the CRBT tone and bridges the call between User A and User B.

In the traditional technology, if the user opens the first ring and the CRBT service at the same time, the CRBT service is often lost. Instead, the No. 1 service server plays a unified ring back tone, or the ringing tone is played by the calling terminal side. For example, the flow chart of the No.1 and CRBT services is shown in Figure 5. User A calls User B, User B signs the number one, and also signs the ring tones. The first one receives the first 200 OK off-hook. The event, whether it is the primary number or the secondary number, is bridged with the calling user A and releases or no longer calls other users.

In a preferred embodiment of the present invention, the first terminal initiates a call to the second terminal that has opened the one-number service, and the ringing event of the second terminal is interrupted when the one-way service server calls the second terminal. After receiving the temporary response of the ringing event carrying the playback media returned by the second terminal, the one-number service server bridges the second terminal with the first terminal, so that the first terminal receives the playback media, and restores the first The ringing event of the second terminal is interrupted. The ringing event of the second terminal is interrupted, and the two terminals are bridged when the interrupt is resumed, so that the calling user can hear the ringing tone of the called party before going off-hook.

Figure 6 is a logic flow diagram of the present invention, and the specific steps are as follows:

Step 1: User A calls user B, and user B signs the number one service and arrives at the number one service server AS.

Step 2: The number service server AS determines whether the user B has signed the same mode, and if yes, performs step 3; otherwise, the user B is in the first pass mode, and step 10 is performed. Step 3: The number service server AS uses the fake media of user A to simultaneously call the primary number user.

B, and the secondary number users Cl, 2, etc. (denoted as Ci), and register user B's 180 ringing event interrupt.

Step 4: The No.1 service server AS determines whether User B returns a temporary response of the 180 ringing event. If yes, go to Step 5. Otherwise, go to Step 8.

Step 5: The service server AS determines whether the received 180 ringing returned by the user B side carries the playback media, and if yes, step 6 is performed. Otherwise, go to step 9.

Step 6, the number of the service Λ The AS bridges the user B and the user A, and restores the interruption of the 180 ringing event of the user B. The user A listens to the playback prompt carried by the user, that is, the ring tone of the user B.

In step 5, user B brings the playback media in the 180ring, and in this step, the AS bridges the caller and the number one primary number, thereby implementing the nesting of the first number and the color ring.

Step 7. The primary number B or the secondary number Ci is off-hook, and the AS bridges it with the user and releases other users. The off-hook user and user A enter the call state. The process ends.

Step 8: When the first 180 ringing event is received by the service server AS, whether it is returned by the primary number or the secondary number, the user A returns a 180 ringing response, does not carry media information, and the user A terminal side plays itself. Ringback tone, or carry playback media information, play a unified one-way service ringback tone. Go to step 7.

Step 9. One-way service server AS resumes the interruption of user B's 180 ringing event. Go to step 8.

The interrupt is resumed so that the signaling flow can continue.

Step 10: - No. Service AS The AS first calls the primary number user B, and registers the interruption of the user B's 180 ringing event.

Step 11: The one-number service server AS determines whether the user B returns a temporary response of the 180 ringing event, and if yes, step 12 is performed. Otherwise, go to step 16.

Step 12: The number of the service server AS determines whether the received 180 ringing returned by the user B side carries the playback media, and if yes, step 13 is performed. Otherwise, go to step 18.

Step 13: The number of services is bridged between the user B and the user A, and the interruption of the 180 ringing event of the user B is resumed, and the user A listens to the playback prompt carried by the user. Step 14: When the one-number service server AS receives the failed final response at a certain time or time, the next user in the call sequence list until the user picks up the phone or the call is completed.

Step 15. The primary number B or the secondary number Ci is off-hook, and the AS bridges it with the user and no longer calls other users. The off-hook user and user A enter the call state. The process ends.

Step 16. The service server AS calls the next user in the sequence list until the user picks up the phone or the call is completed at regular intervals or when the final response to the failure is received.

Step 17: When receiving the first 180 ringing event, the number-of-service service server returns a 180 ringing response to the user A, does not carry the media information, and the user A terminal side plays the ring back tone or carries the playing media information. , play a unified one-way service ringback tone. Go to step 15.

Step 18: The No. Service Server AS resumes the interruption of User B's 180 ringing event. Go to step 16.

It can be seen that this method can not only meet the requirements of the original No. 1 service, but also effectively compensate for the defect that the original No. 1 service and the CRBT service will lose the CRBT when nested.

In order to make the objects, the technical solutions and the advantages of the present invention more clearly, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be arbitrarily combined with each other.

For the No. 1 service, regardless of the simultaneous mode or the synchronous mode, as long as the primary number or the secondary number has a terminal ringing, the one-way service application server AS returns a ringing response to the calling user. For the same mode, it is divided into two scenarios: ringing of the main number and ringing of the main number without ringing. For the smoothing mode, it is also divided into two scenarios: the ringing of the main number and the ringing of the primary number and the ringing of the secondary number.

For the scenario where the ringback response is required to be returned to the calling user, the first one is nested with the CRBT service, as described below. In the following scenarios, the blocks in the figures are a description of one or several steps that are performed later. Figure 7-1 shows the ringing scenario of the primary number in the same mode. The specific signaling procedure is as follows: Step 701: A sends an INVITE request to the one-number AS, the request number is B, and carries its own SDP (Session Description Protocol, session). Describe the protocol) information. The SDP information mainly includes related media information such as an IP address, a port number, an audio and video capability, and an encoding format. User A calls User B, User B signs the No. 1 service, and also subscribes to the CRBT service. The call request first arrives at the No. 1 AS.

Step 702: The number of the AS sends an INVITE request to the CRBT AS. The request number is B, and the SDP fake media information carrying A is sent, that is, the audio and video attribute direction is sendonly. One-way AS registers the 180Ring interrupt for this session.

Step 703: The CRBT sends an INVITE request to B, and the request number is B, and carries the SDP fake media information of A, that is, the audio and video attribute direction is sendonly.

Step 704: The numbering AS sends an INVITE request to the Ci, and the request number is Ci, and carries the SDP fake media information of A, that is, the audio and video attribute direction is sendonly. The first number AS determines that B is in the same mode and calls the primary number B and the secondary number Ci.

Step 705: B returns a 180Ring temporary response to the CRBT AS.

Step 706: The CRBT AS sends an INVITE request to the MRS, and carries the SDP fake media information of A. CRBT AS applies to the MRS for playback resources.

Step 707: The MRS returns a 200 OK (INVITE) final response to the CRBT AS, and carries its own SDP media information, and the audio and video attribute direction is recvonly (receive only).

Step 708: The CRBT AS sends an ACK acknowledgement message to the MRS.

Step 709: The CRBT AS returns a 180Ring temporary response to the One-way AS, and carries the SDP media information of the MRS, and the audio and video attribute direction is recvonly.

Step 710: The number of the AS sends an UPDATE request to the CRBT AS, carrying the SDP information of A. The No.1 AS receives the playback media from the 180 returned by the primary number B, and bridges the user A and the user B to resume the interruption.

Step 711: The CRBT sends a REINVITE request to the MRS, and carries the SDP information of the A. Step 712: The MRS returns a 200 OK (INVITE) final response to the CRBT AS, and carries its own SDP information.

Step 713: The CRBT AS sends an ACK acknowledgement message to the MRS.

Step 714, the CRBT AS returns a 200 OK (UPDATE) final response to the One-way AS, and carries the SDP information of the MRS. Step 715: The number-passing AS returns a 180Ring temporary response to the Α, carrying the SDP information of the MRS.

Step 716: The CRBT AS sends an INFO notification request to the MRS. The CRBT AS requests the MRS to play the CRBT tone for User A.

Step 717, the MRS returns a 200 OK (INFO) final response to the CRBT AS. User A listens to the user

B ring tones. The primary number B and the secondary number Ci are off-hook, and the AS connects the user to the user bridge and releases other users.

Figure 7-2 shows the ringing scenario of the ringing number of the primary number in the same mode. The specific signaling procedure is as follows:

Step 801: A sends an INVITE request to the One-way AS, and the request number is B, and carries its own SDP information. The SDP information mainly includes related media information such as an IP address, a port number, an audio and video capability, and an encoding format. User A calls user B. User B signs the number one service, and also subscribes to the color ring service. The call request first arrives at the number one AS.

Step 802: The number-of-pass AS sends an INVITE request to the CRBT AS, and the request number is B, and the SDP fake media information carrying A is sent, that is, the audio and video attribute direction is sendonly. One-way AS registers the 180Ring interrupt for this session.

Step 803: The CRBT sends an INVITE request to B, and the request number is B, and carries the SDP fake media information of A, that is, the audio and video attribute direction is sendonly.

Step 804, the number-passing AS sends an INVITE request to the Ci, and the request number is Ci, and carries the SDP fake media information of A, that is, the audio and video attribute direction is sendonly. The first number AS determines that B is in the same mode and calls the primary number B and the secondary number Ci.

Step 805, B returns the final response of the 4XX failure to the CRBT AS, 4XX such as 480 is not registered, 486 is busy, 408 is timed out, and the like.

Step 806: The CRBT AS returns the final response of the 4XX failure to the One-way AS.

Step 807: The number of the AS sends an ACK confirmation message to the CRBT AS.

Step 808: The CRBT AS sends an ACK acknowledgement message to B. In step 809, Ci returns a 180Ring temporary response to the one-way AS.

Step 810, - No. The AS returns a 180Ring temporary response to A. The user does not carry the media information, and the user A terminal plays the ringback tone, or carries the playback media information, and plays the unified one-number service ringback tone. The primary number B and the secondary number Ci are off-hook, and the AS connects the user to the user bridge and releases other users.

Figure 7-3 shows the ringing scenario of the primary number in the oscillating mode. The specific signaling procedure is as follows: Step 901: A sends an INVITE request to the one-number AS, and the request number is B, and carries its own SDP information. The SDP information mainly includes related media information such as an IP address, a port number, an audio and video capability, and an encoding format. User A calls user B. User B signs the No. 1 service and also subscribes to the CRBT service. The call request first arrives at the No. 1 AS.

Step 902: The number of the AS sends an INVITE request to the CRBT AS, and the request number is B, and carries the SDP fake media information of A, that is, the audio and video attribute direction is sendonly. The first pass AS calls B in the ringing order list, and registers the 180Ring interrupt of the session.

Step 903: The CRBT sends an INVITE request to B, and the request number is B, carrying A.

SDP fake media information, that is, the audio and video attribute direction is sendonly.

Step 904, B returns a 180Ring temporary response to the CRBT AS.

Step 905: The CRBT AS sends an INVITE request to the MRS, and carries the SDP fake media information of A. CRBT AS applies to the MRS for playback resources.

Step 906, the MRS returns a 200 OK (INVITE) final response to the CRBT AS, carrying its own

SDP media information, the audio and video attribute direction is recvonly.

Step 907: The CRBT AS sends an ACK confirmation message to the MRS.

Step 908: The CRBT AS returns a 180Ring temporary response to the One-way AS, and carries the SDP media information of the MRS, and the audio and video attribute direction is recvonly.

Step 909, the number-pass AS sends an UPDATE request to the CRBT AS, and carries the SDP information of A. The first-pass AS receives the 180-playing playback media returned from the primary number B side, and bridges the user A and the user B to resume the interruption. Step 910: The CRBT AS sends a REINVITE request to the MRS, carrying the SDP information of the UI. Step 91: The MRS returns a 200 OK (INVITE) final response to the CRBT AS, and carries its own SDP information.

Step 912: The CRBT AS sends an ACK acknowledgement message to the MRS.

Step 913, the CRBT AS returns to the No. 1 AS. 200 OK (UPDATE) final response, carrying

SDP information of MRS.

Step 914, the first communication AS returns a 180Ring temporary response to the A, and carries the SDP information of the MRS.

Step 915: The CRBT AS sends an INFO notification request to the MRS. The CRBT AS requests the MRS to play the CRBT tone for User A.

Step 916, the MRS returns a 200 OK (INFO) final response to the CRBT AS. User A listens to the user B ring tones. The AS calls the next user in the sequence list until the user picks up the phone or the call is completed at regular intervals or when the final response to the failure is received. The primary number B and the secondary number Ci are off-hook, and the AS bridges the user with user A and no longer calls other users.

Figure 7-4 shows the ringing mode of the primary number of the ringing mode in the same mode. The specific signaling procedure is as follows:

Step 1001: A sends an INVITE request to the One-way AS, and the request number is B, and carries its own SDP information. The SDP information mainly includes related media information such as an IP address, a port number, an audio and video capability, and an encoding format. User A calls user B. User B signs the number one service, and also subscribes to the color ring service. The call request first arrives at the number one AS.

Step 1002: The number-of-pass AS sends an INVITE request to the CRBT AS, and the request number is B, and the SDP fake media information carrying A is sent, that is, the audio and video attribute direction is sendonly. The first pass AS first calls B and registers the 180Ring interrupt for the session.

Step 1003: The ring back tone AS sends an INVITE request to B, and the request number is B, and carries the A.

Step 1004, B returns the final response of the 4XX failure to the CRBT AS, such as 480 not registered, 486 busy, 408 timeout, and the like. In step 1005, the CRBT AS returns the final response of the 4XX failure to the One-way AS. Step 1006: The number-of-pass AS sends an ACK acknowledgement message to the CRBT AS.

Step 1007: The CRBT AS sends an ACK confirmation message to B.

Step 1008: The number-of-pass AS sends an INVITE request to the Ci, and the request number is Ci, and carries the SDP fake media information of A, that is, the audio and video attribute direction is sendonly. The first number AS determines that B is in the smooth mode. At regular intervals or when the final response to the failure is received, the next user in the call sequence list until the user picks up the phone or the call is completed.

In step 1009, Ci returns a 180Ring temporary response to the one-way AS.

Step 1010: The number of the AS is returned to the A. The 180Ring temporary response does not carry the media information, and the user A terminal side plays the ringback tone itself, or carries the playback media information, and plays the unified No. 1 service ringback tone. The first number AS determines that the primary number B side does not return 180 carrying the playback media, and returns 180 to user A when the first 180 of the secondary number is received. When the AS receives the failed final response at regular intervals, it calls the next user in the sequence list until the user picks up the phone or the call is completed. The primary number B and the secondary number Ci are off-hook, and the AS bridges the user with user A and no longer calls other users.

The following describes the one-number service server that implements the CRBT service in the One-number service, as shown in Figure 8, including the call module and the bridge module, where:

The calling module is configured to receive a call initiated by the first terminal to the second terminal that opens the one-number service, and the ringing event of the second terminal is interrupted when the second terminal is called;

The bridging module is configured to bridge the second terminal with the first terminal after receiving the temporary response of the ringing event carrying the playback media returned by the second terminal, so that the first terminal receives the playback media, and recovers The ringing event of the second terminal is interrupted. Preferably, the bridging module is further configured to resume the ringing event interruption of the second terminal after receiving the temporary response of the ringing event that does not carry the playing media returned by the second terminal.

Preferably, the calling module is further configured to: after receiving the call initiated by the first terminal to the second terminal that opens the one-number service, determine whether the second terminal subscribes to the same mode or the synchronous mode. The calling module determines that the second terminal subscribes to the same mode, and then calls the second terminal in the following manner: The second terminal primary number and secondary number. The calling module determines that the second terminal subscribes to the synchronous mode, and then calls the second terminal by: calling the second terminal primary number first, calling the second terminal secondary number every predetermined time or after receiving the failure response, until A user picks up the phone or all the numbers are called.
