Description

Technical Field

[0001] The present application relates to the field of terminals, and in particular to a method, electronic device, and system for making a call when a video ringback tone is abnormal. Background Art

[0002] With the introduction of voice services based on the Internet Protocol Multimedia Subsystem (IMS), voice call quality has been significantly improved compared to the 2G / 3G era. Operators can now provide high-definition voice and video calls. As an important value-added voice service for operators, the IMS-based CRBT service can provide high-definition and video CRBT experiences compared to the standard-definition CRBT experience under 2G / 3G.

[0003] Video ringback tone (RBT) allows the calling party to view a video clip while waiting for the called party to connect, providing a richer call experience. However, when the RBT function experiences an anomaly, the calling party may be unable to view the video content, often hindering the user's call. For example, the called party may be connected while the calling party is still waiting for the called party to connect. Therefore, ensuring that users can continue to call normally despite RBT anomalies has become a pressing issue. Summary of the Invention

[0004] The present application provides a call method, electronic device, and system when a video ringback tone is abnormal, which enables a communication network device to promptly forward a called end connection notification to a calling end when a video ringback tone is abnormal, thereby reducing the duration of inconsistency between the calling end and the called end states, and improving the call completion rate and quality of voice calls.

[0005] In a first aspect, the present application provides a method for call in abnormal video ringback tone, applied to a first electronic device, a second electronic device and a communication network device, the method comprising: after the first electronic device calls the second electronic device, the communication network device sends a video ringback tone establishment negotiation notification to the first electronic device. The video ringback tone establishment negotiation notification is used for negotiating a video ringback tone port and codec configuration information for playing the video ringback tone between the communication network device and the first electronic device. Within a first specified time length after receiving the video ringback tone establishment negotiation notification, if the communication network device does not complete the video bearer establishment between the first electronic device, the first electronic device disables the video ringback tone port of the first electronic device, and sends a video stream disabling indication to the communication network device. The video ringback tone port of the first electronic device is used for the first electronic device to receive the video data of the video ringback tone, and the video stream disabling indication is used to indicate that the first electronic device has disabled the video stream of the first electronic device. In response to the called terminal connection through notification sent by the second electronic device, the communication network device sends a close video ringback tone port notification to the first electronic device. When receiving the close video ringback tone port notification, the first electronic device judges whether the video ringback tone port in the first electronic device has been disabled. If the video ringback tone port has been disabled, and the communication network device does not send a reply message of the video stream disabling indication, the first electronic device no longer waits for the reply message of the video stream disabling indication, and sends a reply message of the close video ringback tone port notification to the communication network device. In response to the reply message of the close video ringback tone port notification, the communication network device sends the called terminal connection through notification to the first electronic device.

[0006] In a possible implementation, after the first electronic device disables the video ringback tone port of the first electronic device, and sends a video stream disabling indication to the communication network device, the method further comprises: the first electronic device plays a local ringtone, and does not play the video picture and audio of the video ringback tone.

[0007] In a possible implementation, the method further comprises: within the first specified time length after receiving the video ringback tone establishment negotiation notification, if the communication network device has completed the establishment of the video bearer between the first electronic device, the first electronic device sends a calling terminal Qos video stream has been established indication to the communication network device. The calling terminal Qos video stream has been established indication is used to indicate that the video bearer between the communication network device and the first electronic device has been established and completed. The communication network device sends video data and audio data of the video ringback tone to the first electronic device. The video data is used for the first electronic device to play the video picture of the video ringback tone, and the audio data is used for the first electronic device to play the audio of the video ringback tone. The first electronic device rings based on the video data and the audio data.

[0008] In a possible implementation, after the first electronic device rings based on the video data and the audio data, the method further includes: in response to the called terminal on-hook notification sent by the second electronic device, the communication network device sends a close video ringback port notification to the first electronic device. When the close video ringback port notification is received, the first electronic device sends a reply message of the close video ringback port notification to the communication network device. In response to the reply message of the close video ringback port notification, the communication network device sends the called terminal on-hook notification to the first electronic device.

[0009] In a possible implementation, after the first electronic device disables the video ringback port of the first electronic device and sends the video stream disabling indication to the communication network device, the method further includes: the first electronic device stores the first record information. The first record information is used to indicate that the video ringback port of the first electronic device has been disabled. If the video ringback port has been disabled and the communication network device does not send the reply message of the video stream disabling indication, the first electronic device no longer waits for the reply message of the video stream disabling indication, and sends the reply message of the close video ringback port notification to the communication network device, specifically including: the first electronic device reads the first record information and determines that the video ringback port has been disabled. If the communication network device does not send the reply message of the video stream disabling indication and the video ringback port has been disabled, the first electronic device no longer waits for the reply message of the video stream disabling indication, and sends the reply message of the close video ringback port notification to the communication network device.

[0010] In a possible implementation, the method further includes: in response to the called terminal on-hook notification, the first electronic device displays a call interface. The call interface is used for voice call between the first electronic device and the second electronic device.

[0011] In a second aspect, embodiments of the present application provide a communication system comprising a first electronic device, a second electronic device, and a communication network device, wherein: the communication network device is configured to, after the first electronic device calls the second electronic device, send a video ringback ring tone establishment negotiation notification to the first electronic device. The video ringback ring tone establishment negotiation notification is used by the communication network device and the first electronic device to negotiate a video ringback ring tone port and codec configuration information for playing the video ringback ring tone. The first electronic device is configured to, if the communication network device does not complete video bearer establishment between the first electronic device and the communication network device within a first specified time period after receiving the video ringback ring tone establishment negotiation notification, disable the video ringback ring tone port of the first electronic device and send a video stream disable indication to the communication network device. The video ringback ring tone port of the first electronic device is used by the first electronic device to receive video data of the video ringback ring tone, and the video stream disable indication is used to indicate that the first electronic device has disabled the video stream of the first electronic device.

The communication network device is further configured to, in response to the reply message regarding the video ringback tone port closure notification, send a called terminal connection notification to the first electronic device.

[0012] In a possible implementation, the first electronic device is further configured to play a local ring tone, but not play the video image and audio of the video ring tone.

[0013] In one possible implementation, the first electronic device is further configured to, within a first specified duration of receiving the video ringback tone establishment negotiation notification, if the communication network device has completed establishing the video bearer between it and the first electronic device, send a caller-side QoS video stream establishment indication to the communication network device. The caller-side QoS video stream establishment indication is used to indicate that the video bearer between the communication network device and the first electronic device has been established. The communication network device is further configured to send video data and audio data of the video ringback tone to the first electronic device. The video data is used by the first electronic device to play the video image of the video ringback tone, and the audio data is used by the first electronic device to play the audio of the video ringback tone. The first electronic device is further configured to ring based on the video data and the audio data.

[0014] In one possible implementation, the communication network device is further configured to, after the first electronic device rings based on the video data and the audio data, send a video ringback tone port closure notification to the first electronic device in response to the called terminal connection notification sent by the second electronic device. The first electronic device is further configured to, upon receiving the video ringback tone port closure notification, send a reply message to the communication network device regarding the video ringback tone port closure notification. The communication network device is further configured to, in response to the reply message to the video ringback tone port closure notification, send the called terminal connection notification to the first electronic device.

[0015] In one possible implementation, the first electronic device is further configured to: after the first electronic device disables the video ringback tone port of the first electronic device and sends a video stream disabling instruction to the communication network device, store the first record information, wherein the first record information is used to indicate that the video ringback tone port of the first electronic device has been disabled.

[0037] Figure 1A A schematic diagram of the architecture of a communication system 10 provided in an embodiment of the present application.

[0038] like Figure 1A As shown, the communication system 10 may include: an electronic device 100, an electronic device 200 and a communication network device 300. The communication system 10 can be used for voice calls between the electronic device 100 and the electronic device 200 through a cellular network (such as 4G / 5G, etc.). Among them, the electronic device that actively initiates a call request can be called a calling end, and the electronic device that receives the call request can be called a called end. The calling end initiating a call request to the called end can be called the calling end calling the called end. In the embodiment of the present application, the electronic device 100 actively initiates a call request, and the electronic device 200 receives the call request initiated by the electronic device 100 as an example for explanation. Therefore, the electronic device 100 can be called the calling end, the first electronic device, and the electronic device 200 can be called the called end, the second electronic device.

[0039] The electronic device 100 may be a mobile phone, tablet computer, PC, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), etc. The present application does not impose any restrictions on the specific type of the electronic device 100.

[0040] The electronic device 200 may be a mobile phone, tablet computer, PC, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), etc. The present application does not impose any restrictions on the specific type of the electronic device 200.

[0041] The communication network device 300 may include an IMS domain core network (IMS Core), an evolved packet core network (EPC), a ring back tone application server, etc. The communication network device 300 may also be other types of communication network devices, which is not limited in this application. Among them, IMS may refer to an architecture for providing multimedia communication services such as voice, video, and text messages over an Internet Protocol (IP) network, which can achieve secure and reliable multimedia communication between different devices in different networks. The IMS system can enable voice services to be transmitted as data streams in a data bearer network without having to rely on a circuit-switched voice network.

[0042] Electronic device 100 and communication network device 300 can transmit data information to each other, and electronic device 200 and communication network device 300 can also transmit data information to each other. The data information can be communication signaling (hereinafter referred to as signaling) used to operate a voice call service, or voice data when electronic device 100 and electronic device 200 are conducting a voice call, etc. When communication network device 300 is a communication network device in an IMS system, the signaling used to operate the voice call service can be Session Initialization Protocol (SIP) signaling.

[0043] In the embodiment of this application, Figure 1A The communication system 10 shown is only used to explain the present application and does not constitute any limitation to the present application.

[0044] Figure 1B A schematic diagram of a user interface for a video ringback tone provided in an embodiment of the present application.

[0045] Among them, if the called party has activated the video ring back tone service, the calling party can display a video screen and play the corresponding audio when calling the called party and waiting for the called party to connect.

[0046] like Figure 1B As shown, a calling party calls a called party that has subscribed to the video ringback tone service. During the waiting phase before the called party is connected, the calling party may display a user interface 110. This user interface 110 may display an avatar 111 of the called party, status information such as "The other party is ringing," and a video image 112 of the video ringback tone. The calling party may also play the corresponding audio.

[0047] Optionally, the user interface 110 may further display one or more function controls, such as a recording function control, a hold function control, an add call function control, a video call function control, a mute function control, and a contact function control, etc. In other words, the present application does not limit the interface elements displayed in the user interface 110.

[0048] It should be noted that Figure 1B It is only used to illustrate the present application and does not constitute any limitation to the present application.

[0049] Figure 2 A schematic diagram of a call flow with abnormal video ringback tone provided in an embodiment of the present application.

[0050] like Figure 2 As shown, the control process of the video ringback tone may include:

[0051] S201: When a calling terminal (electronic device 100) calls a called terminal (electronic device 200) that has activated the video ringback tone service, the calling terminal sends a call request to the called terminal through the communication network device 300.

[0052] Specifically, when the calling end receives a user's call to the called end, the calling end may send a call request to the communication network device 300. The communication network device 300 may then forward the call request to the called end. The called end may have activated the video ringback tone service, allowing the calling end to display a video image and play corresponding audio while waiting for the called end to connect.

[0053] S202: The communication network device 300 establishes voice bearers with the calling end and the called end respectively.

[0054] The voice bearer can be used to play the audio of the video ringback tone when the calling end is ringing, play the audio when the called end is ringing, transmit voice data when the calling end and the called end are talking, etc.

[0055] S203: The communication network device 300 sends a video ringback tone establishment negotiation notification to the calling party.

[0056] The video ringback tone establishment negotiation notification may be used for: the communication network device 300 and the calling terminal to negotiate the video ringback tone port and codec configuration information for playing the video ringback tone.

[0057] S204: Upon receiving the video ringback tone establishment negotiation notification, the calling end determines whether the video bearer is established.

[0058] In the embodiment of the present application, there is no strict temporal order between the two steps of "video bearer establishment is completed" and "communication network device 300 sends a video ringback ring tone establishment negotiation notification to the calling party." That is, the video bearer can be established before the communication network device 300 sends the video ringback ring tone establishment negotiation notification, or the video bearer can be established after the communication network device 300 sends the video ringback ring tone establishment negotiation notification. Therefore, when the calling party receives the video ringback ring tone establishment negotiation notification, the calling party can determine whether the video bearer is established. In the embodiment of the present application, unless otherwise specified, the video bearer described refers to the video bearer between the communication network device 300 and the calling party for playing the video image in the video ringback ring tone.

[0059] Specifically, when the calling end receives the video ringback tone establishment negotiation notification, the calling end can determine whether the video bearer has been established and set a timer with a specified duration T1. If the communication network device 300 establishes the video bearer quickly and can complete the video bearer establishment before sending the video ringback tone establishment negotiation notification, the calling end can determine that the video bearer has been established when receiving the video ringback tone establishment negotiation notification. If the communication network device 300 establishes the video bearer slowly and does not complete the video bearer establishment before sending the video ringback tone establishment negotiation notification, the calling end can determine that the video bearer has not been established when receiving the video ringback tone establishment negotiation notification.

[0060] S205: If the video bearer is not established, the calling end sends an indication to the communication network device 300 that the calling end QoS video stream is not established.

[0061] The calling end QoS video stream not established indication can be used to indicate that the video bearer between the calling end and the communication network device 300 has not been established, and the negotiation process of the video ringback tone needs to continue.

[0062] S206: Within the specified duration T1 (which may be referred to as the first specified duration) of receiving the video ringback tone establishment negotiation notification, the calling end determines whether the video bearer is established.

[0063] Specifically, if the timer duration does not exceed the specified duration T1, the communication network device 300 completes the establishment of the video bearer between the calling end, and the calling end determines that the video bearer has been established; if the timer duration exceeds the specified duration T1, the communication network device 300 does not complete the establishment of the video bearer between the calling end, and the calling end can determine that the network does not support the video ringback tone function or the video ringback tone has an abnormality.

[0064] S207: If the video bearer is not established within the specified time T1, the calling end disables the video ringback tone port of the calling end and sends a video inactive indication to the communication network device 300.

[0065] The video ringback tone port of the calling end can be used to receive video data in the video ringback tone sent by the communication network device 300 through the video bearer, so that the calling end can play the video image of the video ringback tone based on the video data.

[0066] The calling end's local video stream disabled (videoinactive) indication can be used to indicate to the communication network device 300 that the calling end has disabled its video stream. In this embodiment, the calling end's local video stream disabled (videoinactive) indication can be simply referred to as a video stream disabled indication. Disabling the calling end's video stream means that the calling end has prohibited the continuous streaming of video data for the video ringback tone.

[0067] S208: The communication network device 300 completes the establishment of the video bearer.

[0068] The video bearer may be used by the communication network device 300 to send video data of a video ringback tone.

[0069] S209: The called party rings.

[0070] The ringing of the called end described in the embodiment of the present application may include one or more of the following: playing video images, playing audio, outputting vibration, etc. In some implementations, if the called end plays a video image (also referred to as the video image of the video color vibration of the called end) when ringing, then before this step, the communication network device 300 may complete the establishment of a video bearer (for playing the video image in the video color vibration) between the called end and the communication network device 300. Figure 2 not shown).

[0071] The ringing of the called end can be used to prompt that the called end has received the call request sent by the calling end; the ringing of the calling end can be used to prompt that the call request has been sent to the called end and the calling end is waiting for the called end to connect.

[0072] S210: After the called end rings, the called end may send a notification of the called end ringing to the calling end through the communication network device 300.

[0073] The notification that the called terminal is ringing may be used to prompt the calling terminal, through the communication network device 300, that the called terminal is in a ringing state.

[0074] S211: In response to the notification that the called end has rung, the calling end rings and plays a local ring tone (also called a local ringback tone) without the video image and corresponding audio of the video ringback tone.

[0075] Before this step, because the calling end has disabled the video ringback tone port of the calling end, the calling end has disabled the video stream of the calling end, and the video ringback tone negotiation between the communication network device 300 and the calling end is unsuccessful. Therefore, the communication network device 300 will not send the video data of the video ringback tone through the video bearer, nor will it send the audio data of the video ringback tone through the voice bearer, resulting in the calling end being unable to play the video image of the video ringback tone based on the video data, nor being able to play the audio of the video ringback tone based on the audio data. At this time, the calling end will play the local ringtone stored in the local memory to remind the user that the called end is in a ringing state and the calling end is waiting for the called end to be connected.

[0076] S212: The called party receives the call connection operation.

[0077] S213: In response to the call connection operation, the called party sends a called party connection notification to the communication network device 300.

[0078] The called terminal connection notification may be used to indicate to the communication network device 300 that the called terminal has received a call connection operation (also called an answer operation). At this time, the called terminal interface is in a connected state.

[0079] S214: After receiving the call connection notification from the called terminal, the communication network device 300 sends a video ringback tone port closing notification to the calling terminal, instructing the calling terminal to disable the video ringback tone port of the calling terminal.

[0080] The video ringback tone port deactivation notification can be used by the communication network device 300 to instruct the calling party to disable the video ringback tone port on the calling party. In this embodiment of the present application, "disabling the video ringback tone port on the calling party" can also be referred to as "deactivating the video ringback tone port on the calling party." Specifically, after the communication network device 300 receives the connection notification from the called party and determines that the called party's interface is connected, the communication network device 300 determines that the calling party no longer needs to play the video ringback tone. Therefore, the communication network device 300 sends a video ringback tone port deactivation notification to the calling party.

[0081] S215: The calling end waits for a reply message (referred to as a reply for short) from the communication network device 300 regarding the video stream disable instruction.

[0082] Before this step, since the communication network device 300 does not complete the establishment of the video bearer between the calling terminal and the calling terminal when the timing duration of the timer exceeds the specified duration T1, the calling terminal determines that the network does not support the video ringback tone function or the video ringback tone is abnormal, the calling terminal disables the video ringback tone port and sends a video stream disabling instruction to the communication network device 300. However, the communication network device 300 is still in the process of establishing the video bearer, therefore, the communication network device 300 does not reply to the calling terminal for the video stream disabling instruction, so that when the calling terminal receives the closing video ringback tone port notification, the calling terminal needs to wait for the reply message of the communication network device 300 for the video stream disabling instruction, otherwise the calling terminal cannot perform the subsequent process.

[0083] S216: After the calling terminal receives the reply message of the video stream disabling instruction, the calling terminal can send a reply message of the closing video ringback tone port notification to the communication network device 300.

[0084] S217: The communication network device 300 disconnects the video bearer between the calling terminal and the calling terminal.

[0085] S218: When the video bearer is disconnected, the communication network device 300 sends a called terminal connection notification to the calling terminal.

[0086] S219: In response to the called terminal connection notification, the calling terminal displays a call interface.

[0087] Specifically, when the calling terminal displays the call interface, the interface of the calling terminal is also in the connected state, therefore, the user of the calling terminal and the user of the called terminal can start the voice call.

[0089] As shown in FIG. 8, the call flow signaling interaction can include: Figure 3A-3B Figure 2

[0090] Phase 1: The calling terminal calls the called terminal

[0091] a1. When the calling terminal initiates a call to the called terminal, the calling terminal sends a call request, for example, an INVITE message, to the communication network device 300 (Network), including the telephone number of the calling terminal and the telephone number of the called terminal.

[0092] a2. The communication network device 300 sends a call request response message, for example, a 100 trying message, to the calling terminal, prompting the calling terminal that the communication network device 300 has received the call request.

[0093] ​​a3. The communication network device 300 forwards the call request, such as the aforementioned INVITE message, to the called party.

[0094] a4. The called end sends a call request response message to the communication network device 300, such as a 100trying message, to prompt the communication network device 300 that the called end has received the call request.

[0095] a5. The called end sends a session progress notification message, such as 183Session Progress message, to the communication network device 300, which is used to prompt the calling end through the communication network device 300 that the called end is processing the call request.

[0096] a6. The communication network device 300 forwards a session progress notification message, such as a 183Session Progress message, to the calling end to prompt the calling end that the called end is processing the call request.

[0097] a7. The communication network device 300 establishes a voice bearer with the calling end and the called end respectively.

[0098] For the description of voice bearer, please refer to the above embodiment and will not be repeated here.

[0099] a8. The calling end sends a session progress notification message, such as a PRACK message, to the communication network device 300 to notify the called end that the calling end has received the 183Session Progress message.

[0100] a9. The communication network device 300 forwards a session progress notification message, such as a PRACK message, to the called party to notify the calling party that the calling party has received the 183Session Progress message.

[0101] a10. The called end sends a session progress notification to the communication network device 300, receiving a response message such as a 200OK message of PRACK, which is used to prompt the calling end through the communication network device 300. The called end has learned that the calling end has received a 183Session Progress message.

[0102] a11. The communication network device 300 forwards the session progress notification reception response message, such as a 200OK message of PRACK, to the calling end.

[0103] a12. The calling end sends a session negotiation message to the communication network device 300, such as an UPDATE message 1 for negotiating voice session description protocol (SDP) information, which is used for the calling end and the called end to negotiate voice-related SDP information, including the audio ports supported by the calling end and the called end, codec negotiation configuration information, etc.

[0104] a13. The communication network device 300 forwards the session negotiation message, such as UPDATE message 1, to the called party.

[0105] a14. The called end sends a session negotiation response message to the communication network device 300, such as a 200OK message of the UPDATE message 1, to notify the calling end that the called end has successfully processed the UPDATE message 1.

[0106] In the embodiment of the present application, the UPDATE message 1 and the 200OK message of the UPDATE message 1 are used together by the calling end and the called end to negotiate the Session Description Protocol SDP information.

[0107] a15. The communication network device 300 forwards the session negotiation response message, such as the 200OK message of the UPDATE message 1, to the calling end.

[0108] In the embodiments of the present application, the order of implementing a1 to a15 is not specifically limited.

[0109] Phase 2: The calling party rings

[0110] a16. The communication network device 300 sends a video ringback tone establishment negotiation notification to the calling party, such as UPDATE message 2.

[0111] The video ringback tone negotiation notification may include the video ringback tone port identifier and codec negotiation configuration information of the communication network device 300. The video ringback tone port of the communication network device 300 is used by the communication network device 300 to transmit the video data of the video ringback tone to the calling party via the video bearer. For example, UPDATE message 2 may include parameters such as m=video39022RTP / AVP 114 and a=content:g.3gpp.cat.

[0112] a17. Upon receiving the video ringback tone establishment negotiation notification, the calling end determines whether the video bearer is established.

[0113] If the video bearer is not established, the calling end sends a reply message to the communication network device 300 to establish a negotiation notification of the video ringback tone, such as the 200OK message of the UPDATE message 2, carrying the calling end Qos video stream is not established indication, such as qoslocalnone.

[0114] For example, the 200OK message of the UPDATE message 2 may include the video ringback tone port identifier of the calling end, such as parameter m=video 60010RTP / AVPF 114, and parameter a=curr:qos local none indicating that the QoS video stream of the calling end is not established.

[0115] a19. Within the specified time duration T1 of receiving the video ringback tone establishment negotiation notification, the calling end determines whether the video bearer is established.

[0116] a20. If the T1 video bearer is not established within the specified time, the calling party disables the video ringback tone port of the calling party.

[0117] a21. The calling end sends an UPDATE message 3 to the communication network device. The UPDATE message 3 carries a video stream disabled (videoinacitve) indication.

[0118] Exemplarily, the UPDATE message 3 may include but is not limited to parameters m=video 0RTP / AVPF 114, a=inactive, etc. Among them, m=video 0RTP / AVPF 114 indicates that the video ringback tone port of the calling end is disabled, and a=inactive indicates that the video stream of the calling end is disabled.

[0119] a22. The communication network device 300 completes the establishment of the video bearer.

[0120] a23. The called party rings.

[0121] a24. After the called end rings, the called end sends a notification that the called end has been ringing, such as 180Ring, to the calling end through the communication network device 300 to prompt the calling end that the called end is already in a ringing state.

[0122] a25. In response to the notification that the called party has been ringing, the calling party rings and plays a local ring tone (also called a local ringback tone), without the video image and corresponding audio of the video ringback tone.

[0123] Before this step, because the calling end has disabled the video ringback tone port of the calling end, the video stream of the calling end is also disabled, and the video ringback tone negotiation between the communication network device 300 and the calling end is unsuccessful. Therefore, the communication network device 300 will not send the video real-time transport protocol (RTP) packet of the video ringback tone (that is, the aforementioned video data) through the video bearer, nor will it send the audio RTP packet of the video ringback tone (that is, the aforementioned audio data) through the voice bearer. As a result, the calling end cannot play the video image of the video ringback tone based on the video RTP packet, nor can it play the audio of the video ringback tone based on the audio RTP packet. At this time, the calling end will play the local ringtone stored in the local memory to prompt the called end that it is in the ringing state and the calling end is waiting for the called end to be connected.

[0124] Phase 3: The called party connects the call

[0125] a26. The called party receives the call connection operation.

[0126] a27. In response to the call connection operation, the called party sends a called party connection notification to the communication network device 300, such as a 200OK message of the INVITE.

[0127] a28. After receiving the connection notification from the called party, the communication network device 300 sends a notification to close the video ringback tone port to the calling party, such as UPDATE message 4.

[0128] Exemplarily, the UPDATE message 4 may carry a video ringback tone port disabling instruction, such as parameters m=video0RTP / AVP 114, a=content:g.3gpp.cat, etc.

[0129] a29. After receiving UADATE message 4, the calling end determines whether the communication network device 300 replies to UPDATE message 3.

[0130] If the communication network device 300 does not reply to the UPDATE message 3, the calling end sends an UPDATE 491Request Pending to the communication network device 300, indicating that the calling end process is blocked.

[0131] Because the communication network device 300 does not reply to UPDATE message 3, the calling end cannot perform corresponding processing when receiving the notification of closing the video ringback tone port. At this time, in response to the notification of closing the video ringback tone port, the calling end sends UPDATE 491Request Pending to the communication network device 300, indicating to the communication network device 300 that the calling end process is blocked.

[0132] a31. The communication network device 300 performs the same steps as a28, ie, sends a notification to the calling party to close the video ringback tone port, such as UPDATE message 4, and triggers the calling party to execute a29 and subsequent processes.

[0133] a32. If the communication network device 300 replies to the UPDATE message 3 to the calling end (that is, the communication network device 300 sends a reply message to the UPDATE message 3 to the calling end), the calling end sends a reply message to the UPDATE message 4 (that is, a reply message to close the video ringback tone port notification) to the communication network device 300, such as the 200OK message of the UPDATE message 4.

[0134] a33. The communication network device 300 disconnects the video bearer between it and the calling party.

[0135] a34. After the video bearer is disconnected, the communication network device 300 forwards the called terminal connection notification to the calling terminal, such as the 200OK message of the INVITE.

[0136] a35. In response to the called terminal connection notification, the calling terminal sends a confirmation message, such as an ACK message, to the communication network device 300 to prompt the called terminal that the calling terminal is aware that the called terminal is connected.

[0137] a36. The communication network device 300 forwards a confirmation message, such as an ACK message, to the called party. The calling party and the called party can then conduct a normal voice call.

[0138] a37. The call interface is displayed on the calling end.

[0139] It should be noted that Figure 3A-3B It is used to illustrate the present application and does not constitute any limitation.

[0140] It should be noted that UPDATE message 1, UPDATE message 2, UPDATE message 3, UPDATE message 4, etc., represent a certain type of UPDATE message. Each UPDATE message of the same type may have a different number depending on the timing of its transmission. For example, UPDATE message 4 represents a message for disabling the video ringback tone port. Each UPDATE message 4 may have a different number depending on the timing of its transmission. For example, UPDATE message 4 sent by communication network device 300 at T1 seconds may be numbered 1; UPDATE message 4 sent by communication network device 300 at T2 seconds may be numbered 2. The same applies to UPDATE message 1, UPDATE message 2, UPDATE message 3, and so on.

[0141] Figures 4A-4D A user interface diagram of a control process for a group of video ringback tones provided in an embodiment of the present application.

[0142] like Figure 4A As shown, when the calling end dials the called end and the called end has not yet ringed, the calling end may display a user interface 410. The user interface 410 is used to prompt the user that the calling end has sent a call request to the called end. The user interface 410 may display the called end user's name such as "Mom", the called end user's phone number such as "183*******0126", and a call progress prompt such as "Dialing...".

[0143] like Figure 4B As shown, when the called end receives a call request from the calling end, the called end rings and may display a user interface 420. The user interface 420 may display the name of the calling end user, such as "Lily", the calling end user's phone number, such as "133*******0143", a "Reject" control 421, and an "Answer" control 422. The "Reject" control 421 may be used to receive a touch operation on it, causing the called end to reject the voice call with the calling end; the "Answer" control 422 may be used to receive a touch operation on it (i.e., a call connection operation), allowing the called end and the calling end to conduct the voice call normally.

[0144] like Figure 4B As shown, when the called party is ringing, the calling party can display a ringing prompt message "The other party is ringing" on the user interface 410, so that the user of the calling party can perceive that the called party is ringing. At this time, because the calling party has disabled the video ringback tone port of the calling party, there is no video image and corresponding audio of the video ringback tone, but the local ring tone can be played.

[0145] like Figure 4B-4C As shown, when the called party receives and responds to a touch operation on the "Answer" control 422 (i.e., a call connection operation), the called party may display a user interface 430. This user interface 430 may display a hang-up control 431 and a voice call prompt such as "Call in Progress 00:01." However, at this point, the calling party is waiting for a reply message from the communication network device 300 regarding the video stream disable indication, so the local ringtone is still playing, without the video image and corresponding audio of the video ringback tone. The called party has actually been connected, but the calling party is still waiting for the called party to connect because it has not received the called party's connection notification. At this point, the calling party still displays user interface 410.

[0146] like Figure 4DAs shown, when the calling end receives a reply message from the communication network device 300 regarding the video stream disable indication, the communication network device 300 disconnects the video bearer between the calling end and the called end. The calling end then receives a connection notification from the called end. At this point, the calling end and the user end can conduct a voice call. The calling end may display a user interface 440, which displays a hang-up control 441 and a voice call prompt such as "Call in progress 00:01." The called end may display a user interface 430, which displays a hang-up control 431 and a voice call prompt such as "Call in progress 00:03." It can be seen that there is a difference in call duration between the calling and called ends.

[0147] It should be noted that Figures 4A-4D It is only used to illustrate the present application and does not constitute any limitation.

[0148] From the above Figure 2 、 Figure 3A-3B and Figures 4A-4D As can be seen from the illustrated embodiment, if the communication network device 300 establishes the video bearer at a slow speed, and the communication network device 300 completes the establishment of the video bearer only after the calling terminal sends a video stream disable instruction to the communication network device 300, then when the calling terminal receives the notification of closing the video ringback tone port and does not receive a reply message to the video stream disable instruction, the calling terminal needs to wait for the reply message of the communication network device 300 to the video stream disable instruction, otherwise the calling terminal cannot proceed with the subsequent process. At this time, the called terminal is in the connected state, but the calling terminal is not in the connected state and is still waiting for the called terminal to connect. The states of the two ends are not synchronized, resulting in the problem that after the called terminal receives the call connection operation, the calling terminal cannot connect the call for a long time, and the users at both ends cannot conduct normal voice calls.

[0149] Therefore, an embodiment of the present application provides a method for making a call when a video ringback tone (RBT) is abnormal, including: when a calling end sends a video stream disable indication to a communication network device 300, and the calling end receives a video ringback tone port closure notification from the communication network device 300, the calling end can check whether the video ringback tone port of the calling end has been disabled. If so, the calling end can terminate the relevant process of the video stream disable indication through the protocol stack, that is, no longer wait for the communication network device 300 to reply to the video stream disable indication. Then, the calling end sends a reply message to the video ringback tone port closure notification to the communication network device 300. In response to the reply message to the video ringback tone port closure notification, the communication network device 300 disconnects the video bearer with the calling end and forwards the called end connection notification to the calling end, ensuring a smooth call connection. In this way, the communication network device 300 can promptly forward the called end connection notification to the calling end, thereby reducing the duration of the inconsistency between the calling end and the called end states, and improving the call connection rate and voice call quality.

[0150] Figure 5 A specific flow chart of a method for making a call when a video ringback tone is abnormal is provided in an embodiment of the present application.

[0151] like Figure 5 As shown, the specific implementation process of the video ringback tone control method may include:

[0152] S501: When the calling end (electronic device 100) calls the called end (electronic device 200) which has activated the video ringback tone service, the calling end sends a call request to the called end through the communication network device 300.

[0153] S502: The communication network device 300 establishes a voice bearer with the calling end and the called end respectively.

[0154] S503: The communication network device 300 sends a video ringback tone establishment negotiation notification to the calling party.

[0155] S504: Upon receiving the video ringback tone establishment negotiation notification, the calling end determines whether the video bearer is established.

[0156] S505: If the video bearer is not established, the calling end sends an indication to the communication network device 300 indicating that the calling end QoS video stream is not established.

[0157] S506: Within the specified time duration T1 of receiving the video ringback tone establishment negotiation notification, the calling end determines whether the video bearer is established.

[0158] S507: If the video bearer is not established within the specified time T1, the calling end disables the video ringback tone port of the calling end and sends a video stream disable (video inactive) indication to the communication network device 300.

[0159] S508: The communication network device 300 completes the establishment of the video bearer.

[0160] S509: The called party rings.

[0161] S510: After the called end rings, the called end may send a notification of the called end ringing to the calling end through the communication network device 300.

[0162] S511: In response to the notification that the called end has rung, the calling end rings and plays a local ring tone (also called a local ringback tone) without the video image and corresponding audio of the video ringback tone.

[0163] S512: The called party receives the call connection operation.

[0164] S513: In response to the call connection operation, the called party sends a called party connection notification to the communication network device 300.

[0165] S514: After receiving the called terminal on-hook notification, the communication network device 300 sends a close video CRBT port notification to the calling terminal, indicating to the calling terminal to disable the video CRBT port of the calling terminal.

[0166] The descriptions of S501-S514 can refer to the descriptions of S201-S214, and will not be repeated here.

[0167] S515: When receiving the close video CRBT port notification, the calling terminal determines whether the video CRBT port of the calling terminal has been disabled.

[0168] Specifically, when the calling terminal sends the video inactive indication to the communication network device 300, the calling terminal can store record information (which can be referred to as first record information) indicating that the video CRBT port of the calling terminal has been disabled. For example, the record information indicating that the video CRBT port of the calling terminal has been disabled can include: 1, a video CRBT port disabled identifier, such as m=video0 RTP / AVPF 114; 2, a calling terminal video stream inactive identifier (optional), such as a=inactive. When the calling terminal receives the close video CRBT port notification, the calling terminal can determine that the video CRBT port of the calling terminal has been disabled based on the record information indicating that the video CRBT port of the calling terminal has been disabled, that is, the calling terminal does not play the video screen and the corresponding audio of the video CRBT at this time.

[0169] In other implementations, the calling terminal can also determine that the video CRBT port of the calling terminal has been disabled through other record information or other identifiers, which are not limited in the present application.

[0170] S516: If the video CRBT port of the calling terminal has been disabled, the calling terminal terminates the corresponding process of the video inactive indication through the protocol stack.

[0171] The calling terminal terminates the corresponding process of the video inactive indication through the protocol stack, that is, the calling terminal can terminate the listening of the video inactive indication through the protocol stack, and no longer waits for the reply message of the video inactive indication sent by the communication network device 300.

[0172] S517: The calling terminal sends a reply message of the close video CRBT port notification to the communication network device 300.

[0173] S518: The communication network device 300 disconnects the video bearer between the calling terminal.

[0174] S519: After the video bearer is disconnected, the communication network device 300 sends a called terminal on-hook notification to the calling terminal.

[0175] S520: In response to the called party's connection notification, the calling party displays a call interface.

[0176] The description of S518 to S520 may refer to the description of S217 to S219 mentioned above.

[0177] Combine Figure 5 , Figure 6A-6B A signaling interaction diagram of a call method when a video ringback tone is abnormal provided in an embodiment of the present application.

[0178] like Figure 6A-6B As shown, the signaling interaction of the video ringback tone control method may include:

[0179] The description of b1 to b28 can refer to the description of a1 to a28 above, which will not be repeated here.

[0180] b29. When receiving the notification of closing the video ringback tone port, the calling end determines whether the video ringback tone port of the calling end has been disabled.

[0181] For the description of this step, please refer to the description of S515 above.

[0182] b30. If the video ringback tone port of the calling party has been disabled, the calling party terminates the process of UPDATE message 3 through the protocol stack.

[0183] For the description of this step, please refer to the description of S516 above.

[0184] b31. The calling end sends a reply message to the communication network device 300 to close the video ringback tone port notification, that is, a reply message to the UPDATE message 4, such as a 200OK message to the UPDATE message 4.

[0185] For the description of b32 to b36, please refer to the description of a33 to a37 above.

[0186] In some implementations, if the UPDATE message sent by the communication network device 300 in step b28 is not a notification to close the video ringback tone port (for example, an UPDATE message 41 is sent to instruct the calling party to make other updates), the calling party executes the aforementioned Figure 3B a29~a37 in, but Figure 3B A slight difference is that if the calling end determines that the communication network device 300 has replied to the UPDATE message 3 , the calling end replies to the UPDATE message 41 , that is, sends a 200 OK message of the UPDATE message 41 .

[0187] Figure 7 A user interface diagram of a video ringback tone control method provided in an embodiment of the present application.

[0188] like Figure 7 As shown, when the called end receives the call request from the calling end, the called end rings and can display the user interface 420. The description of the user interface 420 can refer to the aforementioned Figure 4B The calling end can display a ringing reminder message "The other party is ringing" on user interface 410, allowing the calling end user to know that the called end is ringing. At this time, since the calling end has disabled video streaming, there is no video image or corresponding audio of the video ringback tone, but the local ringtone can be played.

[0189] When the called end receives and responds to the touch operation on the "Answer" control 422 (i.e., the call connection operation), the called end can display a user interface 430. The user interface 430 can display a hang-up control 431 and a voice call prompt "Call in progress 00:01", etc. By implementing the video ringback tone control method provided in the present application, the communication network device 300 can promptly forward the called end connection notification to the calling end, at which point the calling end and the user end can conduct a voice call. The calling end can display a user interface 440, which displays a hang-up control 441 and a voice call prompt "Call in progress 00:01", etc. It can be seen that after implementing this solution, the duration of the inconsistent status between the calling end and the called end is greatly shortened, thereby improving the voice call quality and the call completion rate of the voice call.

[0190] In one possible implementation, the embodiment of the present application provides another method for making a call when the video ringback tone is abnormal:

[0191] Figure 8A A flowchart illustrating a specific implementation of another method for making a call when a video ringback tone is abnormal is provided in an embodiment of the present application.

[0192] like Figure 8A As shown, the specific implementation process may include:

[0193] S801: When the calling end (electronic device 100) calls the called end (electronic device 200) which has activated the video ringback tone service, the calling end sends a call request to the called end through the communication network device 300.

[0194] S802: The communication network device 300 establishes a voice bearer with the calling end and the called end respectively.

[0195] The description of S801 to S802 may refer to the aforementioned S201 to S202.

[0196] S803: The communication network device 300 completes the establishment of the video bearer with the calling party.

[0197] S804: The communication network device 300 sends a video ringback tone establishment negotiation notification to the calling party.

[0198] S805: Upon receiving the video ringback tone establishment negotiation notification, the calling end determines whether the video bearer is established.

[0199] The description of S804 to S805 may refer to the description of S203 to S204 mentioned above.

[0200] S806: If the video bearer has been established, the calling end sends an indication to the communication network device 300 that the calling end QoS video stream has been established.

[0201] The calling-end QoS video stream established indication may be used to indicate to the communication network device 300 that the video bearer between the communication network device 300 and the calling end has been established.

[0202] S807: The called party rings.

[0203] S808: After the called end rings, the called end may send a notification of the called end ringing to the calling end through the communication network device 300.

[0204] S809: In response to the notification that the called party has been ringing, the communication network device 300 sends the video data of the video ringback tone to the calling party via the video bearer, and sends the audio data of the video ringback tone to the calling party via the voice bearer.

[0205] S810: After receiving the video data and audio data, the calling end rings.

[0206] Prior to this step, the video ringback tone port on the calling party was not disabled, and the calling party's video stream was normal. Therefore, the video ringback tone negotiation between the communication network device 300 and the calling party was successful. The communication network device 300 can send the video ringback tone's video data to the calling party via the video bearer and can send the video ringback tone's audio data to the calling party via the voice bearer. When the calling party rings, it can play the video ringback tone's audio based on the audio data sent by the communication network device 300 and display the video image of the video ringback tone based on the video data of the video ringback tone.

[0207] S811: The called party receives a call connection operation.

[0208] S812: In response to the call connection operation, the called party sends a called party connection notification to the communication network device 300.

[0209] S813: After receiving the connection notification from the called party, the communication network device 300 sends a notification of closing the video ringback tone port to the calling party.

[0210] The description of S811 to S813 may refer to the aforementioned S212 to S214.

[0211] S814: The calling end may send a reply message to the communication network device 300 to notify the closing of the video ringback tone port.

[0212] S815: The communication network device 300 disconnects the video bearer between the calling party and the communication network device 300.

[0213] S816: After the video bearer is disconnected, the communication network device 300 sends a called terminal connection notification to the calling terminal.

[0214] S817: In response to the called party's connection notification, the calling party displays a call interface.

[0215] Among them, the description of S815 to S817 can refer to the aforementioned S217 to S219.

[0216] Combine Figure 8A , Figure 8B A signaling interaction diagram of another call method when a video ringback tone is abnormal provided in an embodiment of the present application.

[0217] like Figure 8B The signaling interaction of the video ringback tone control method may include:

[0218] The description of c1 to c7 can refer to the description of a1 to a7, which will not be repeated here.

[0219] c8. The communication network device 300 completes the establishment of the video bearer with the calling party.

[0220] The description of c9 to c18 can refer to the description of a8 to a17, which will not be repeated here.

[0221] c19. If the video bearer has been established, the calling end sends a reply message to the communication network device 300 to notify the establishment of the video ringback tone negotiation, such as the 200OK message of the UPDATE message 2, carrying the calling end Qos video stream has been established indication, such as qoslocalrecv.

[0222] For example, the 200OK message of the UPDATE message 2 may include the video ringback tone port identifier of the calling party, such as parameter m=video 60010RTP / AVPF 114, parameter a=curr:qoslocal recv indicating that the calling party's QoS video stream has been established, and the like.

[0223] The description of c20 to c21 can refer to the above a23 to a24.

[0224] c22. The communication network device 300 sends the audio RTP packet of the video ringback tone to the calling party via the voice bearer.
