[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 29, 2023, with application number 202311870146.7 and titled “Call control method, device, electronic device and readable storage medium,” the entire contents of which are incorporated by reference into this application.

For example, video color ringing services based on Voice over Long-Term Evolution (VoLTE) or Voice over New Radio (VoNR) are available. Video color ringing services provide the called user with a video during the call establishment process, enriching the ringing experience of the called user's terminal.

[0005] In related technologies, the transmission of video color ring services requires a dedicated video bearer configured by the network. During the call establishment process of the terminal, if the network does not promptly configure the dedicated video bearer, the terminal may cause the call establishment to be interrupted because the video data of the video color ring service cannot be transmitted in time, thereby causing the call service to fail. Summary of the Invention

[0025] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0026] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

For example, at least one of a, b, and c can be represented by: "a", "b", "c", "a and b", "a and c", "b and c", and "a, b, and c", where a, b, and c can be single or multiple. Similarly, "at least two" means two or more, and its meaning is similar to "at least one".

[0028] The following explains the nouns, terms or coined words involved in the embodiments of the present application.

[0029] 1. Video color vibration

[0030] Customized by the calling or called user, a video media is provided to the called user to enrich the ringing service of the called user's mobile phone and is presented on the called side.

[0031] 2. IP Multimedia Subsystem (IMS)

[0032] IMS is a new multimedia service format that meets end-user demands for newer, more diverse, and multi-media services. Considered a core technology for next-generation mobile networks, IMS is a key approach to facilitating the convergence of mobile and fixed networks and introducing differentiated services such as triple-integration of voice, data, and video. In the 4G-LTE era, IMS (VoLTE) technology allows telephony and data services to share the same IP-based bearer network. Once connected to the IMS network, user terminals can engage in video or voice calls with other users.

[0033] 3. VoLTE

[0034] VoLTE is a voice service based on IMS and an IP data transmission technology. All services are concentrated on the 4G network, realizing the unification of data and voice services under the same network, and providing high-quality voice and video call services.

[0035] With the advancement of communication technology, users not only enjoy clearer voice calls but also more innovative services based on VoLTE networks, such as video ringback tone (RBT). Video ringback tone allows callers to see a video instead of just hearing audio while waiting for a call to be connected. Because video is more complex than audio, it is crucial to ensure both audio quality and a clear and smooth video image.

[0036] Currently, the transmission of video color ringing requires a dedicated video bearer configured by the network. When a called terminal that has activated the video color ringing service receives a call request, if the network fails to configure the dedicated video bearer in a timely manner, the called terminal may have its call establishment process interrupted by the network because the video color ringing service cannot be executed normally, resulting in call establishment failure.

[0037] The call control method provided in the embodiment of the present application is that when a called terminal with a video color ring service activated receives a call request, if the network does not promptly configure a dedicated video bearer, the called terminal can disable the video port and send a first indication message to the network device to instruct the network device to also disable the video port, thereby downgrading the call with the video color ring service to an ordinary voice call, avoiding the failure of the call to be established normally due to the network device not promptly configuring a dedicated bearer for transmitting video data, thereby improving the success rate of the call service.

[0038] Furthermore, video ringback tone or video ringback ring services require the terminal and the network to negotiate video-related information, such as key information like port number and bitrate. Only when these information are agreed upon can the video be played in a timely manner with clear and smooth image quality. In poor network environments or when relevant protocols are imperfect, this negotiation may fail, resulting in abnormal call disconnections or video screen distortion, freezes, and mosaics. Furthermore, even if an agreement is reached, packet loss may occur when the network sends the relevant information in a poor network environment, causing the video image displayed by the terminal to be distorted.

[0039] The embodiment of the present application provides a call control method. The execution subject can be an electronic device, or at least one of the functional modules and entity modules in the electronic device that can implement the call control method. The specific method can be determined according to actual usage requirements and is not limited by the embodiment of the present invention.

[0040] The call control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0041] FIG1 is a flow chart of a call control method according to an embodiment of the present application. As shown in FIG1 , the call control method may include the following steps S201 to S205:

[0042] Step S201: The network device sends a first call establishment request to the terminal.

[0043] In some embodiments, the terminal may be a called terminal.

[0044] In some embodiments, upon receiving a second call establishment request from a calling terminal, the network device may send a first call establishment request to a called terminal (ie, a terminal) to establish a call between the called terminal and the calling terminal.

[0045] In some embodiments, the first call establishment request may be an invite request.

[0046] Step S202: When the terminal activates the video color ring service, a first call establishment request is received.

[0047] In some embodiments, the video color ring service requires that when the called terminal is in idle state when receiving an incoming call from the calling terminal, the called terminal displays and plays the video color ring during the ringing phase of the audio call or video call according to the video color ring media negotiation requirements.

[0048] It should be noted that video color ringing is a service provided by the called terminal during the period when the called terminal receives a call establishment request. If the called terminal has activated the video color ringing service, the call establishment request received is related to the color ringing service, that is, the video color ringing service will be executed during the call period before the call is connected, for example, the video of the video color ringing will be displayed.

[0049] Step S203: during the call establishment process based on the call establishment request, if the terminal fails to successfully establish a dedicated video bearer for the terminal within a preset time period, the terminal closes the video port and sends a first indication message to the network device.

[0050] The video dedicated bearer is used to transmit video data of a video color ring service, and the first instruction message is used to instruct to shut down a video port of a network device.

[0051] In some embodiments, after receiving the first call establishment request, the terminal can execute a call establishment process based on the first call establishment request. During the call establishment process, the called terminal generates a ringback tone and sends it to the calling terminal. After the called terminal picks up the phone, the network device sends a "connectivity information" to the called terminal, indicating that the call to the called terminal has been established.

[0052] In some embodiments, the dedicated video bearer may be QCI 2, that is, a dedicated bearer with a QCI (QoS Class Identifier) ​​of 2.

[0053] It should be noted that QoS (Quality of Service) provides end-to-end service quality assurance for various services based on their different needs, and can be used to establish dedicated channels for transmitting voice and video data.

[0054] In some embodiments, when a video call is established, the dedicated video bearer may be used to transmit video data of the video call during the call after the call establishment is completed.

[0055] It should be noted that the protocol stipulates that voice data requires a voice-dedicated channel with QCI 1, video data requires a video-dedicated channel with QCI 2, and other data has other data channels with the default carry QCI 5.

[0056] It should be noted that the above-mentioned video-dedicated bearer can also be called a video-dedicated bearer.

[0057] In some embodiments, the video port may be a port for transmitting video data.

[0058] Exemplarily, the port information of the video port may be a port number, and the port number may be 0 or other values.

[0059] It can be understood that the port number of the video port is 0, which indicates that the video port is not open (for example, disabled) or the video port is invalid.

[0060] It should be noted that the port number "0" refers to an invalid port, that is, this port cannot be used, which can be understood as closing or disabling the port. When the port number of the terminal's video port is 0, it indicates that the terminal does not need to transmit video data.

[0061] In some embodiments, the first indication message may be an update signaling, which is a signaling used to negotiate with a network device about specific media information such as audio or video of a call.

[0062] For example, the specific information package in the update is called a Session Description Protocol (SDP) request. The SDP request may include information such as voice / video ports, bandwidth, level information, supported protocols, etc.

[0063] In some embodiments, the first indication message includes first update request information, where the first update request information is used to request that the port information of the video port of the network device be updated to preset port information to close the video port of the network device.

[0064] Exemplarily, the first update request information may be an SDP request, and the SDP request includes audio and video media parameters.

[0065] Exemplarily, the above-mentioned preset port information may be 0.

[0066] In some embodiments, after the terminal receives the first call establishment request, it starts a first timer and performs timing according to a preset timing duration. After the first timer expires, if the dedicated video bearer between the terminal and the network device is not successfully established, the video port of the terminal is disabled and a first indication message is sent to the network device.

[0067] Step S204: when the network device fails to successfully establish a video dedicated bearer for the terminal within a preset time period during the call establishment process based on the first call request, the network device receives first indication information from the terminal.

[0068] Step S205: The network device closes the video port of the network device based on the first instruction information.

[0069] In some embodiments, the network device may update the port information of the video port of the network device to 0 according to the preset port information in the first indication information sent by the terminal, so as to close the video port of the network device.

[0070] In some embodiments, upon receiving the first indication message, the network device may send a first response message to the terminal to confirm that the port information of the video port is set to 0.

[0071] In some embodiments, the first response message may be a 200 ok for update signaling.

[0072] For example, the specific information packet of 200 ok for update is called SDP answer (SDP response), and the SDP answer may include information such as voice or video port, bandwidth, level information, supported protocols, etc.

[0073] It should be noted that 200 OK for update is a response from the terminal or network to the network or terminal initiating an update.

[0074] In some embodiments, after the video port is closed, the video color ring service may be cancelled, or the video content of the video color ring service may be cancelled while the audio content may continue to play.

[0075] The following embodiments illustrate the process of the above call control method by using specific examples.

[0076] For example, the terminal has activated the video ringing function. After receiving the invite request, the terminal starts the QoS (qosReservationTimer) timer as the time for the terminal to wait for the establishment of a dedicated video bearer; if the time specified by the QoS timer is reached, the terminal detects that the network device has not established a dedicated video bearer for the terminal, then the terminal actively initiates a resource reservation update signaling to the network, and lets the SDP request in the update signaling carry the video port, and actively sets the video port to 0, negotiates with the network device, and the network device updates the video port information on the network side by replying 200ok for update signaling and also sets the video port to 0.

[0077] It should be noted that if the network normally establishes a video dedicated carrier, the video port is a set of six digits, not 0. The terminal in the embodiment of the present application actively sets the video port to 0. Setting it to 0 means that the video port is not open or there is no video port.

[0078] It should be noted that if the network device does not configure a dedicated video bearer for the terminal in a timely manner, the terminal and the network will not be able to transmit video data. The terminal may report an error code 580, or the network may send an error code such as 503, thereby ending the call. When the terminal detects a video ring and the network has not configured a dedicated video bearer, it will actively initiate an update signaling with the video port as 0. In this way, even if the network device does not configure a dedicated video bearer, the terminal and the network device will no longer send some error codes, thereby avoiding call service failure.

[0079] In the related art, during call establishment, if a dedicated voice bearer QCI1 or video bearer QCI2 is not recommended within 6 seconds, the terminal will report 580, or the network will send some error code, thus terminating the call and causing the call service to fail. In the embodiment of the present application, if the dedicated video bearer QCI2 is not established within the preset time, the terminal proactively initiates an operation to carry the video port and set the port to 0, which can promptly downgrade the video color ringing call to a regular voice call. This can prevent the problem of the network sending some error code to the terminal and hanging up the call due to the failure to establish a dedicated video bearer in time, thereby improving the success rate of the call service.

[0080] The call control method provided in an embodiment of the present application receives a first call request when a terminal activates a video color ring service. During the call establishment process based on the call establishment request, if a dedicated video bearer for the terminal is not successfully established within a preset time period, the terminal closes the video port of the terminal and sends a first indication message to a network device, wherein the dedicated video bearer is used to transmit video data for the video color ring service, and the first indication message is used to instruct the closing of the video port of the network device. Through this method, during the call establishment process of the terminal, if the network fails to promptly configure the dedicated video bearer, the terminal can send the first indication message to the network device to instruct the network device to close the video port, thereby canceling the video color ring service. This prevents the network device from interrupting the call establishment process when the video color ring service is abnormal, thereby improving the success rate of the call service.

[0081] In some embodiments, during the process of executing a call establishment based on a call establishment request, the call control method provided in the embodiment of the present application may include the following steps S206 to S208:

[0082] Step S206: When the dedicated video bearer is successfully established within the preset time period, the network device sends a second update request message to the terminal.

[0083] Step S207: If the dedicated video bearer is successfully established within the preset time period, the terminal sends a second update response message to the network device upon receiving the second update request message from the network device.

[0084] Step S208: The network device receives the second update response information from the terminal.

[0085] Among them, the above-mentioned second update request information is used to request negotiation of network resources for transmitting video data, and the above-mentioned second update response information carries a first bandwidth value, the first bandwidth value is the maximum bandwidth value corresponding to the first video level, the first video level is the highest video level supported by the terminal, and the above-mentioned maximum bandwidth value is the maximum bandwidth value for transmitting a single session.

[0086] In some embodiments, during the call establishment process based on the call establishment request, if the video dedicated bearer is successfully established within a preset time period, the network device sends a second update request message to the terminal and receives a second update response message from the terminal.

[0087] In some embodiments, the second update request information may be information carried by update signaling.

[0088] In some embodiments, the second update request information may include a video parameter, where the video parameter indicates a video level. The higher the level, the better the video quality.

[0089] Exemplarily, the video parameter may be profile level id=3.0.

[0090] It should be noted that level is used to constrain information such as video resolution, bit rate, or frame rate. Level 3.1 is higher definition than level 3.0. According to the protocol specification, the maximum bandwidth AS in SDP is 960, and the subsequent network bandwidth is also 960kbps. However, the bit rate of the video source actually provided by the network may exceed 960kbps, resulting in network packet loss and causing video mosaics.

[0091] In some embodiments, the second update response information may be information carried by 200 OK for update signaling. Exemplarily, the second update response information may be information included in an SDP answer.

[0092] It should be noted that when the video level of the network device and the terminal is 3.0, the bandwidth value supported by the network device is greater than the maximum bandwidth value corresponding to the video level 3.0 of the terminal, and the terminal supports video level 3.1, the bandwidth value indicated by the terminal through the second update response message is the maximum bandwidth value corresponding to the video level 3.1.

[0093] In some embodiments, the terminal sends the maximum bandwidth corresponding to the highest video level supported by the terminal to the network device by replying the second update response information.

[0094] For example, the maximum video level supported by the terminal may be 3.1, and the maximum bandwidth value of a single session corresponding to the maximum video level may be 2162.

[0095] It should be noted that the protocol stipulates that the maximum AS value corresponding to video level 3.0 is 960, and the maximum bandwidth (AS value) corresponding to video level 3.1 is 2162.

[0096] It should be noted that AS can represent the maximum bandwidth value of a single session.

[0097] The following embodiments illustrate the process of the above call control method by using specific examples.

[0098] For example, within the time specified by the QoS timer, the network device establishes a dedicated video bearer for the terminal. The network will negotiate video color ring related information with the terminal. If the update signaling sent by the network device carries the video parameter profile level id = 3.0, the terminal replies 200 ok for update to the network, and the terminal checks whether the maximum supported level is 3.1. If so, the maximum value AS2162 corresponding to level 3.1 supported by the terminal is filled in the SDP answer of the 200 ok for update signaling, instead of the maximum AS value 960 corresponding to level id 3.0 supported by the terminal.

[0099] In conventional signaling, when the network sends an update, if the level carried is level 3.0, and the terminal replies with "update for 200ok" and the level is 3.0, then the maximum AS value is 960. If the network device actually sends level 3.1 video, this may cause video data to be lost during transmission. In an embodiment of the present application, when it is detected that the terminal supports level 3.1 and the network sends level 3.0, the terminal indicates in the reply "200ok for update" the AS value corresponding to the maximum video level supported by the terminal, for example, the maximum AS value of level 3.1 is 2162. In this way, by indicating the maximum AS value within the capability range, more video data can be transmitted at the same time, avoiding the situation where the terminal replies with "960" according to the protocol but the actual bandwidth used by the network video source is greater than 960, causing the network to discard some video packets, causing abnormal problems such as color vibration, screen distortion, and freezes on the terminal display, thereby improving the reliability of video transmission.

[0100] In some embodiments, the call control method provided in the embodiments of the present application may include the following steps S209 and S210:

[0101] Step S209: The terminal receives the third update request information from the network device.

[0102] Among them, the third update request information is used to request negotiation of network resources for transmitting call data after the call is successfully established. The above-mentioned third update request information includes a second bandwidth value, which is: the bandwidth value of a single session determined by the network device for transmitting call data, and the second bandwidth value is less than the maximum bandwidth value corresponding to the highest video level supported by the terminal.

[0103] Step S210: The terminal sends third update response information to the network device.

[0104] Among them, the above-mentioned third update response information carries a third bandwidth value, and the third bandwidth value is: the bandwidth value determined by the terminal for transmitting call data after the call is successfully established. The third bandwidth value is the bandwidth value required for a single session for the terminal to transmit call data. The third bandwidth value is used to transmit call data after the call is successfully established. The third bandwidth value is the bandwidth value for a single session for transmitting call data.

[0105] In some embodiments, the third update response information is used to indicate a bandwidth value required for a single session to transmit call data. For example, the call data may include video call data.

[0106] In some embodiments, the third update request information may be information carried by update signaling.

[0107] In some embodiments, the second bandwidth value may be greater than 960 and less than 2160.

[0108] In some embodiments, the third update request information may be information carried by 200 ok for update signaling.

[0109] In some embodiments, the third bandwidth value may be 2160.

[0110] In some embodiments, before step S209, the call control method provided in the embodiment of the present application may further include the following step A1:

[0111] Step A1: The network device sends a third update request message to the terminal.

[0112] In some embodiments, the network device may send a third update request message to the terminal to negotiate with the terminal about network resources for transmitting call data, for example, a bandwidth value for a single session for transmitting call data.

[0113] In some embodiments, after receiving the third update request information, the terminal sends a third update response information to the network device, and the third update response carries the bandwidth value for transmitting call data after the call is successfully established.

[0114] Exemplarily, after receiving the update signaling from the network device, the terminal sends a 200 ok for update signaling carrying a bandwidth value of 2160 to the network device, so as to negotiate with the network device to set the maximum bandwidth value to 2160.

[0115] In some embodiments, the call request is used to request to establish an audio call, and the third bandwidth value is the second bandwidth value;

[0116] Alternatively, the call request is used to request establishment of a video call, and the third bandwidth value is the maximum bandwidth value.

[0117] For example, after receiving the third update request information, the terminal may detect whether the call is a voice call (i.e., an audio call) or a video call. If the call is detected to be a voice call, the terminal may send the third update request information to the network device including the second bandwidth value. Alternatively, if the call is detected to be a voice call, the terminal may send the third update request information to the network device including the maximum bandwidth value.

[0118] In some embodiments, after a call is successfully established, if the call is a video call, the maximum bandwidth value can be maintained, that is, the maximum bandwidth value for transmitting the video color ring service can be maintained to transmit the video call data; or, after a call is successfully established, if the call is an audio call, the current maximum bandwidth value can be switched to a second bandwidth value, and the second bandwidth value can be used to transmit the audio call data. In this way, the terminal can maintain the maximum bandwidth value for transmitting video call data during the video call, avoiding packet loss during the video call, thereby improving the video call quality. Alternatively, the terminal can reduce the bandwidth used for data transmission during the audio call, using a smaller bandwidth value to transmit audio call data, thereby saving wireless network resources.

[0119] It is understandable that the transmission of call data for video calls is more complicated than that for audio calls. Video calls must ensure normal sound while ensuring clarity and smoothness of the video image. Therefore, a larger bandwidth can be allocated for the transmission of call data for video calls to ensure the quality of the video call.

[0120] In an embodiment of the present application, when negotiating with the network device about the bandwidth value for transmitting call data after a call is successfully established, the terminal can determine the bandwidth value for transmitting call data after a subsequent call is successfully established based on the established call type, and send this bandwidth value to the network device, so that when making a voice call, the call data is transmitted using a smaller bandwidth value, and when making a video call, the call data is transmitted using a larger bandwidth value, thereby avoiding packet loss caused by using a smaller bandwidth value when transmitting call data for a video call, thereby improving the video call effect.

[0121] In some embodiments, the above step S210 may include the following steps S211 and S212:

[0122] Step S211: The network device receives the third update response information from the terminal.

[0123] Step S212: The network device determines the third bandwidth value as the bandwidth value of a single session for transmitting call data.

[0124] For example, upon receiving the third update request message from the terminal, if the bandwidth value carried in the third update request message is 2160, the network device transmits call data to the terminal according to the bandwidth value after the call is established. This allows the transmission of video call data with the terminal using a large bandwidth, thereby improving communication performance.

[0125] The following embodiments illustrate the process of the above call control method by using specific examples.

[0126] For example, if the initial call is a video call, the terminal responds to the update signaling sent by the network by sending a 200 OK for update, and still sets the maximum AS value to 2162. In this way, the terminal maintains the maximum AS value of 2162 after the call is connected. This prevents the network from discarding some video packets due to the AS bit rate of the video source actually sent by the network exceeding the maximum AS value negotiated between the network and the terminal before the call is connected, thereby preventing abnormal issues such as video distortion and mosaics during the video call. This improves the video call quality.

[0127] It should be noted that after the call is connected, that is, after the call is established, the terminal and the network device will no longer negotiate the AS through update signaling. Taking into account that if the initial call is a video call, the video will still be displayed after the call is connected, that is, a dedicated video bearer is still required. Therefore, when it is determined that the initial call is a video call, the terminal and the network device will still use the maximum bandwidth value when negotiating the bandwidth value, so as to ensure the normal execution of subsequent video call services.

The second bandwidth value is less than a maximum bandwidth value corresponding to the highest video level supported by the terminal.

[0173] The above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or, under the premise that there is no contradiction, can also be executed in combination with each other. The specific implementation can be determined according to actual usage requirements, and the embodiments of the present application do not limit this.

[0174] The call control method provided in the embodiment of the present application can be executed by a call control device. In the embodiment of the present application, the call control device provided in the embodiment of the present application is described by taking the call control method executed by the call control device as an example.
