[0034] It should be noted that the modification of "one" or "multiple" mentioned in the present disclosure is illustrative rather than limiting, and those skilled in the art should understand that, unless otherwise explicitly indicated in the context, it should be understood as "one or more".

[0035] The names of the messages or information exchanged between the devices in the embodiments of the present disclosure are only for illustrative purposes, and are not intended to limit the scope of the messages or information.

[0036] The establishment of a data channel (DC) requires network resources to be guaranteed, and if network resources are not reserved, the data channel cannot be established. The current video ringtone is implemented based on a voice data channel, and the bandwidth of the voice data channel is only 2.1M. The encoding format (only supporting H264 encoding) and file size of the video ringtone media file are strictly limited. Due to these limitations of the voice data channel, the clarity of the transmitted video ringtone is low, the user interaction experience is poor, and the development of the video ringtone service is limited.

[0037] With the development of 5th Generation Mobile Communication Technology (5G) enhanced call, the video ringback tone data channel will become an indispensable technology. At present, the 4th Generation Mobile Communication Technology (4G) network and the 5th Generation Mobile Communication Technology (5G) network support the resource reservation mechanism, but the overseas heterogeneous network does not support the resource reservation mechanism, resulting in that the video ringback tone data channel negotiation will not be carried out in the case of not supporting the resource reservation mechanism.

[0038] Therefore, in order to solve the above problems, the embodiment of the present disclosure provides a video ringback tone data transmission method, which establishes a video ringback tone data channel between the video ringback tone platform and the calling terminal by the way of media negotiation in the case that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism. The video ringback tone data channel can provide resource reservation for the calling terminal when the video ringback tone platform transmits the related data of the video ringback tone to the calling terminal in the case that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism.

[0039] FIG. 1 shows a flowchart of a video ringback tone transmission method provided by an exemplary embodiment of the present disclosure. As shown in FIG. 1, in the case that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism, when the calling terminal initiates a call request to the called terminal, the calling terminal sends a call configuration update request to the core network device, and the call configuration update request carries the first identification information of the calling terminal supporting the resource reservation mechanism (step 101). In the method of the exemplary embodiment of the present disclosure, the core network device is described by taking the Call Session Control Function (CSCF) device as an example.

[0040] The core network device receives the call configuration update request; based on the first identification information of the calling terminal supporting the resource reservation mechanism carried by the call configuration update request, updates the current call configuration information to obtain target call configuration information; wherein the target call configuration information includes the second identification information that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism.

[0041] For example, the second identification information can be a private header field added in the header field of the INVITE information, such as one of P-DC-Enable, P-Enable-dc, or Precondition-Enable-dc, and the like, which is used to represent that the current network does not support the resource reservation mechanism, and the calling terminal supports the resource reservation mechanism.

[0042] The core network device generates a data channel establishment request based on the target call configuration information, and sends the data channel establishment request to the video CRBT platform (step 102).

[0043] The video CRBT platform receives the data channel establishment request, updates the media negotiation information based on the target call configuration information in the data channel establishment request, obtains target media negotiation information, and sends the target media negotiation information to the calling terminal through the core network device (step 103). The target media negotiation information includes negotiation parameters of the video CRBT channel.

[0044] The calling terminal returns response information for the target call configuration information (step 104), representing whether the calling terminal completes the resource reservation; when it is determined that the calling terminal completes the resource reservation, triggering the media negotiation with the calling terminal using the target media negotiation information.

[0045] After the calling terminal receives the INVITE information contained in the target media negotiation information, the video CRBT platform identifies that the calling terminal supports the resource reservation mechanism according to the Precondition-Enable-dc identification in the private header field, and performs compatible processing.

[0046] At the same time, the video CRBT platform transmits the target call configuration information to the called terminal (step 105). For example, the video CRBT platform can send the called terminal through the core network device without the header field Precondition-Enable-dc information, and without carrying support:precondition. The called terminal will respond without supporting the resource reservation mechanism according to the Offer / Answer, that is, the called terminal still does not reserve resources. At this time, the called terminal returns response information for the target call configuration information (step 106), representing that the called terminal does not support the resource reservation mechanism.

[0047] For example, the video CRBT platform adds standard protocol related parameters (i.e. Requrie precondition) in the 183 reply to the core network device and the calling terminal, requiring the calling terminal to use the resource reservation mechanism in the subsequent media negotiation.

[0048] For example, the target media negotiation information can be:

[0049] Here, the target media negotiation information can include updated media session description information, and the video ringback platform can add a standard protocol related support resource reservation mechanism (Precondition) parameter in the updated media session description (Session Description Protocal, SDP) information. The updated media session description information can include capability description information of the video ringback data channel to be established. The video ringback media m1 / m2 / m4 carried by the updated media session description information has ADC1 and ADC2, m1 / m2 carries a = content: g.3gpp.cat, and m6 carries a = content: dc.cat.

[0050] For example, the capability description information of the video ringback data channel can include the following contents:

[0051] For example, the updated media session description information can be as follows:

[0052] The core network device reserves resources for the calling terminal after receiving the target media negotiation information. That is, the calling terminal and the called terminal are processed separately, the calling terminal uses a process that supports resource reservation to create a data channel, and the called terminal remains in a process that does not support resources for normal connection processing.

[0053] The calling terminal receives the target media negotiation information and, in the case of completing resource reservation, sends response information for the target media negotiation information to the video ringback platform.

[0054] The video ringback platform determines that the calling terminal completes resource reservation based on the response information after receiving the response information for the target media negotiation information sent by the calling terminal, and performs media negotiation with the calling terminal according to the ringback service mechanism based on the target media negotiation information.

[0055] For example, the video ringback platform can send a media negotiation request to the calling terminal and receive response information for the media negotiation request from the calling terminal (steps 107 and 108). The response information for the media negotiation request from the calling terminal can be used to represent the negotiation result of the media negotiation. When it is determined that the negotiation result of the media negotiation is successful, a video ringback data channel between the video ringback platform and the calling terminal is established; wherein the video ringback data channel is used to provide resource reservation for the calling terminal when the video ringback platform transmits related data of the video ringback to the calling terminal in the case that the current network does not support resource reservation and the calling terminal supports the resource reservation mechanism.

[0056] For example, when the target media negotiation information (UPDATE) arrives at the calling terminal, the calling terminal responds with 200UPDATE after receiving the UPDATE. After the calling terminal completes media negotiation and resource reservation for the video ringback tone data channel, it sends an UPDATE, and the video ringback tone platform responds with 200UPDATE. The video ringback tone platform and the calling terminal establish a connection using Datagram Transport Layer Security / Stream Control Transmission Protocol (DTLS / SCTP) for the video ringback tone data channel, and send video ringback tone data to the calling terminal through the video ringback tone data channel (step 109), and the video ringback tone is played on the calling terminal.

[0057] Because this video ringback tone data channel is not limited by bandwidth, media file encoding format, or file size, it can guarantee the clarity of the corresponding video ringback tone when displayed on the calling terminal, thus improving the user experience. This video ringback tone channel can promote the upgrading of video ringback tones, driving the evolution of traditional video ringback tones towards immersive, interactive, and multi-dimensional experiences, such as digital human ringback tone services, building a new form of immersive and interactive 5G video, and further promoting the development of video ringback tone services on communication networks.

[0058] In some embodiments, the video ringback tone platform can establish a dedicated quality of service stream or a dedicated bearer, and establish a video ringback tone data channel between the video ringback tone platform and the calling terminal on the dedicated quality of service stream or dedicated bearer, which can guarantee the transmission quality of video ringback tones.

[0059] In some embodiments, the called terminal receives a call request and performs an off-hook operation (call answering operation) or a call hang-up operation in response to the call request, sending a call request response information to the video ringback tone platform; wherein, the call request response information indicates that the called terminal performed a call answering operation or a call hang-up operation in response to the call request. The video ringback tone platform receives the call request response information (step 110), stops transmitting video ringback tone data to the calling terminal through the video ringback tone data channel (step 111), and restores the calling terminal's media negotiation process to a process that does not support resource reservation, establishing a call between the two parties.

[0060] For example, when the called terminal performs an off-hook operation, it sends a 200 INVITE to the video ringback tones platform. The video ringback tones platform responds with an ACK. Then, the video ringback tones platform sends a re-INVITE without carrying an SDP. The called terminal responds with a 200 re-INVITE carrying an SDP.

[0061] The video ringback platform encapsulates the SDP of the called terminal into an UPDATE sent to the calling terminal, and the calling terminal replies with a 200 UPDATE.

[0062] The video ringback platform sends a 200 INVITE to the calling terminal, the calling terminal replies with an ACK, the video ringback platform encapsulates the SDP of the calling terminal into the ACK and sends it to the called terminal, the video ringback platform stops sending video ringback data to the calling terminal, the calling terminal stops playing the video ringback, and the calling terminal and the called terminal enter into a call.

[0063] Based on this, the disclosure embodiment provides a video ringback data transmission method, which can be executed by a video ringback platform or a chip applied to the video ringback platform.

[0064] Exemplarily, the video ringback platform described above can be a standalone physical server, a server cluster composed of multiple physical servers or a distributed system, or a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, content delivery network (CDN), and big data and artificial intelligence platform, and the disclosure exemplary embodiment does not limit this.

[0065] FIG. 2 shows a flowchart of another video ringback transmission method provided by the disclosure exemplary embodiment. As shown in FIG. 2, the video ringback data transmission method includes:

[0066] S201, when the calling terminal initiates a call request to the called terminal, receiving a data channel establishment request sent by a core network device based on the call request; wherein the call request carries first identification information for representing that the calling terminal supports a resource reservation mechanism, and the data channel establishment request carries target call configuration information generated by the core network device based on the first identification information, the target call configuration information representing that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism;

[0067] S202, updating the current media negotiation information based on the target call configuration information to obtain target media negotiation information;

[0068] S203, performing media negotiation with the calling terminal by using the target media negotiation information, and establishing a video ringback data channel between the video ringback platform and the calling terminal when it is determined that the negotiation result of the media negotiation is negotiation success;

[0069] S204, transmitting video ringback data to the calling terminal under the condition of resource reservation through the video ringback data channel.

[0070] Specifically, in the case that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism, when the calling terminal initiates a call request to the called terminal, the calling terminal can generate a session configuration update request based on the call request and send the session configuration update request to the core network device. The call request can carry first identification information representing that the calling terminal supports the resource reservation mechanism. Therefore, the session configuration update request generated based on the call request also carries the first identification information.

[0071] The core network device receives the session configuration update request and updates the current session configuration information based on the first identification information carried in the session configuration update request to obtain target session configuration information. The core network device can also generate a data channel establishment request based on the target session configuration information and send the data channel establishment request to the video ringback tone platform. The target session configuration information can represent that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism.

[0072] The video ringback tone platform receives the data channel establishment request and updates the current media negotiation information based on the target session configuration information carried in the data channel establishment request to obtain target media negotiation information. Here, the current media negotiation information is applicable to the case that the resource reservation mechanism is not supported, while the calling terminal in the example embodiment of the present disclosure supports the resource reservation mechanism, so the current media negotiation information needs to be updated to obtain the target media negotiation information supporting the resource reservation mechanism. Examples of the target media negotiation information can be referred to the foregoing, which will not be described here.

[0073] Then, the video ringback tone platform can perform media negotiation with the calling terminal by using the target media negotiation information, and establish a video ringback tone data channel between the video ringback tone platform and the calling terminal when it is determined that the negotiation result of the media negotiation is negotiation success. After the video ringback tone data channel is established, the video ringback tone data can be transmitted to the calling terminal under the condition of resource reservation through the video ringback tone data channel, and since the video ringback tone data channel is not limited by bandwidth, encoding format and file size of the media file, the clarity of the corresponding video ringback tone when it is displayed on the calling terminal is guaranteed, and the user experience is improved.

[0074] According to the technical scheme of the example embodiment of the present disclosure, when the calling terminal initiates a call request to the called terminal, a data channel establishment request sent by the core network device based on the call request is received; wherein the call request carries first identification information representing that the calling terminal supports the resource reservation mechanism, and the data channel establishment request carries target call configuration information generated by the core network device based on the first identification information, the target call configuration information representing that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism; the current media negotiation information is updated based on the target call configuration information to obtain target media negotiation information; the target media negotiation information is used for media negotiation with the calling terminal, and when it is determined that the negotiation result of the media negotiation is negotiation success, a video color ring platform and the calling terminal are connected by a video color ring data channel; and the video color ring data is transmitted to the calling terminal under the condition of resource reservation through the video color ring data channel. In the case that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism, the video color ring data channel between the video color ring platform and the calling terminal is established by the way of media negotiation, and the video color ring data can be transmitted to the calling terminal under the condition of resource reservation by using the video color ring data channel. The video color ring data channel is not limited by bandwidth, encoding format and file size of media files, so that the definition of the corresponding video color ring when displayed on the calling terminal can be guaranteed, and the user experience is improved.

[0075] In some embodiments, the target call configuration information includes second identification information, and the second identification information represents that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism.

[0076] The current media negotiation information is updated based on the target call configuration information to obtain target media negotiation information, which can include:

[0077] The data channel establishment request is parsed to obtain the target call configuration information.

[0078] The second identification information in the target call configuration information is obtained, and the current media negotiation information is updated based on the second identification information to obtain target media negotiation information.

[0079] Specifically, the target call configuration information can include second identification information, and the example embodiment of the present disclosure can represent that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism by the second identification information.

[0080] Exemplarily, the second identification information can be one of private header fields added in a header field of the target call configuration information (such as INVITE information), such as P-DC-Enable, P-Enable-dc, or Precondition-Enable-dc, and the like, and is used to represent that the current network does not support the resource reservation mechanism and the calling terminal supports the resource reservation mechanism.

[0081] After receiving the data channel establishment request, the video ringback tone platform can parse the data channel establishment request to obtain the target call configuration information, then obtain the second identification information in the target call configuration information, and update the current media negotiation information based on the second identification information to obtain target media negotiation information.

[0082] Here, the current media negotiation information can be used to implement media negotiation between the video ringback tone platform and the calling terminal in the case that the current network supports the resource reservation mechanism. Therefore, the second identification information is used to update the current media negotiation information to obtain target media negotiation information, which can be used to implement media negotiation between the video ringback tone platform and the calling terminal in the case that the current network does not support the resource reservation mechanism.

[0083] In some embodiments, the method can further include:

[0084] sending the target call configuration information to the called terminal;

[0085] receiving first response information returned by the called terminal, the first response information being used to represent that the called terminal does not support the resource reservation mechanism.

[0086] Specifically, after parsing the data channel establishment request to obtain the target call configuration information, the video ringback tone platform can further send the target call configuration information to the called terminal through the core network device, so as to inform the called terminal that the calling terminal will perform the media negotiation process supporting the resource reservation mechanism in the subsequent video ringback tone transmission process of the calling terminal.

[0087] The called terminal receives the target call configuration information and sends first response information to the video ringback tone platform. The video ringback tone platform receives the first response information returned by the called terminal. Here, the first response information can be used to represent that the called terminal still adopts the resource reservation mechanism that does not support the resource reservation mechanism in the subsequent video ringback tone transmission process of the calling terminal.

[0088] In some embodiments, the media negotiation with the calling terminal by using the target media negotiation information can include:

[0089] sending the target media negotiation information to the calling terminal;

[0090] receive the second response information returned by the calling terminal, the second response information being used to represent whether the calling terminal completes the resource reservation;

[0091] trigger the media negotiation with the calling terminal by using the target media negotiation information when it is determined that the second response information represents that the calling terminal completes the resource reservation.

[0092] Specifically, when the video ringback tone platform performs the media negotiation with the calling terminal, the video ringback tone platform can first send the target media negotiation information to the calling terminal. The calling terminal receives the target media negotiation information, starts to perform the resource reservation operation, and sends the second response information to the video ringback tone platform according to the completion of the resource reservation operation. Here, the second response information can be the response information to the target media negotiation information, which is used to inform the video ringback tone platform whether the calling terminal completes the resource reservation.

[0093] The video ringback tone platform receives the second response information returned by the calling terminal, and starts to trigger the media negotiation with the calling terminal by using the target media negotiation information according to the ringback tone service mechanism when it is determined that the second response information represents that the calling terminal completes the resource reservation.

[0094] Based on this, the video ringback tone platform of the example embodiments of the present disclosure can trigger the media negotiation with the calling terminal by using the target media negotiation information in the case that the calling terminal completes the resource reservation, thereby creating a prerequisite condition for the establishment of the video ringback tone data channel.

[0095] In some embodiments, triggering the media negotiation with the calling terminal by using the target media negotiation information when it is determined that the second response information represents that the calling terminal completes the resource reservation can include:

[0096] sending a media negotiation request to the calling terminal when it is determined that the second response information represents that the calling terminal completes the resource reservation, the media negotiation request being used to instruct the calling terminal to perform the media negotiation with the video ringback tone platform by using the target media negotiation information;

[0097] receiving third response information returned by the calling terminal, the third response information being used to represent the negotiation result of the media negotiation.

[0098] Specifically, the video ringback tone platform can send the media negotiation request to the calling terminal when it is determined that the second response information represents that the calling terminal completes the resource reservation. The calling terminal receives the media negotiation request, performs the media negotiation with the video ringback tone platform by using the target media negotiation information under the instruction of the media negotiation request, generates the third response information to the media negotiation request, and sends the third response information to the video ringback tone platform. The video ringback tone platform receives the third response information returned by the calling terminal.

[0099] The third response information can be used to represent a negotiation result of the media negotiation between the video ringback tone platform and the calling terminal. The negotiation result of the media negotiation can be negotiation success or negotiation failure, which is not limited here.

[0100] When it is determined that the negotiation result of the media negotiation is negotiation success, a video ringback tone data channel between the video ringback tone platform and the calling terminal is established. After the video ringback tone data channel is established, the video ringback tone data can be transmitted to the calling terminal under resource reservation through the video ringback tone data channel, so that the definition of the corresponding video ringback tone when displayed on the calling terminal can be ensured, and the user experience can be improved.

[0101] In some embodiments, the method can further include:

[0102] receiving call request response information of the called terminal, the call request response information representing that the called terminal performs a call receiving operation or a call hang-up operation on the call request;

[0103] stopping transmitting the video ringback tone data to the calling terminal through the video ringback tone data channel.

[0104] Specifically, the video ringback tone platform can receive the call request response information of the called terminal, and the call request response information represents that the called terminal performs a call receiving operation or a call hang-up operation on the call request.

[0105] The called terminal can perform a call receiving operation on the call request, or perform a call hang-up operation on the call request, or perform no operation on the call request.

[0106] When the called terminal performs a call receiving operation or a call hang-up operation on the call request, the video ringback tone platform can stop transmitting the video ringback tone data to the calling terminal through the video ringback tone data channel. At this time, the calling terminal stops playing the video ringback tone and starts establishing a call connection with the called terminal.

[0107] When the called terminal performs no operation on the call request, the video ringback tone platform can continue to transmit the video ringback tone data to the calling terminal through the video ringback tone data channel.
