Detailed Description
In order to solve the above problems in the prior art, embodiments of the present invention provide a holographic video call method, a video server, and a mobile terminal, in the scheme, after a core network sends holographic video call data to be presented by a first mobile terminal at a second mobile terminal to the video server, the video server encrypts the holographic video call data, specifically, shell data is used to process the holographic video call data, so that, after the second mobile terminal receives data sent by the core network and processed by the shell data on the holographic video call data, a holographic video with a virtual 3D shell is presented. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1A, in an embodiment of the present invention, a holographic video call method 10 is provided, including:
step 100: receiving holographic video call data sent by a first mobile terminal through a core network;
step 110: processing the holographic video call data by adopting shell data;
step 120: and sending the processed holographic video call data to a second mobile terminal through the core network, so that the second mobile terminal presents a holographic video with a virtual 3D shell.
In the embodiment of the present invention, before step 100 is executed, further, both the first mobile terminal and the second mobile terminal need to register in the core network, so that the subsequent first mobile terminal and the second mobile terminal may interact with the core network, and a specific registration process may adopt the prior art, which is not specifically limited herein.
In this embodiment of the present invention, before step 100 is executed, further, in order to improve security, before the first mobile terminal interacts with the core network, the core network needs to perform authentication and authorization on the first mobile terminal, and a specific authentication and authorization process may use a currently existing technology, which is not specifically limited herein.
In this embodiment of the present invention, optionally, the processing the holographic video call data by using shell data includes:
adding the shell data before a start bit of valid information in the holographic video call data.
In this embodiment of the present invention, if the shell data is added before the start bit of the valid information in the holographic video call data, the field where the shell data is located may be located before the field where the valid information in the holographic video call data is located, but is not adjacent to the field, in the scenario shown in fig. 1B, the video corresponding to the invalid information in the holographic video call data displayed in the second mobile terminal also has a shell. Thus, in the scenario shown in fig. 1B, there may be a problem of wasting resources, and in order to save resources, optionally, a field where the shell data is located before a field where the valid information in the holographic video call data is located, and is adjacent to the field, in the scenario shown in fig. 1C, in this scenario, a video corresponding to the invalid information in the holographic video call data presented in the second mobile terminal does not have a shell, and a video corresponding to the valid information in the holographic video call data presented in the second mobile terminal only has a shell, so that a problem of wasting resources may be avoided.
It should be noted that, in the embodiment of the present invention, it is only required to ensure that the field in which the shell data is located before the field in which the valid information in the holographic video call data is located, and a specific positional relationship is not further limited.
In the embodiment of the present invention, the shell data is obtained according to a shell generation instruction sent by the core network or is preset, that is, before the shell data is used to process the holographic video call data, the shell data is obtained first, and specifically, how to obtain the shell data may be two ways, one is obtained according to the instruction of the core network, and the other is locally generated in advance, and it is not necessary to perform a generation operation according to the instruction of the core network.
In this embodiment of the present invention, when the shell data is obtained according to the shell generation instruction sent by the core network, the core network may trigger to execute an operation of sending the shell generation instruction according to a message of the first mobile terminal, for example, when the first mobile terminal sends a request for establishing a data session connection to the core network, the request carries an identifier indicating whether to encrypt, and the request for establishing a data session connection is as follows:
< PDU Session attribute > < Data network name > < PDU session type > < SSC MODE > < PDU session ID >
When the identifier is 1, the holographic video call needs to be encrypted, and when the identifier is 0, the holographic video call does not need to be encrypted. Of course, it may also be that when the identifier is 0, it indicates that the holographic video call needs to be encrypted, and when the identifier is 1, it indicates that the holographic video call does not need to be encrypted, which kind of identifier is used for indicating encryption, which kind of identifier is used for indicating that no encryption is performed, and no specific limitation is made herein; meanwhile, which field of the request the identifier is located in is not specifically limited, that is, as long as the request carries an identifier that can be recognized by the core network and is used for indicating whether to encrypt, which identifier is specifically located at which position, and which identifier is specifically used for indicating that the identifier is encrypted and unencrypted, which is not specifically limited in the embodiments of the present invention.
It has been described above that the request for establishing the data session connection carries an identifier indicating whether to encrypt, and in the embodiment of the present invention, optionally, a separate message may also be used to indicate whether the holographic video call needs to be encrypted to the core network, which is not limited herein.
In the embodiment of the present invention, whether the holographic video call between the first mobile terminal and the second mobile terminal needs to be encrypted may be determined according to a user instruction.
For example, when the first mobile terminal receives an instruction of performing a holographic video call with the second mobile terminal, an "encryption" option and an "non-encryption" option are presented in the interface, and after a user clicks the "encryption" option in the interface of the first mobile terminal, when the first mobile terminal sends a request for establishing a data session connection to the SMF, the request carries an encryption identifier.
Certainly, in order to improve user experience, in the embodiment of the present invention, the first mobile terminal may also indicate, to the core network, that the holographic video call needs to be encrypted when locally determining that the current user meets the encryption condition, for example, when the first mobile terminal determines that the user is in a relatively close identity relationship with the user of the second mobile terminal, such as "family", "coworkers", and the like, the first mobile terminal may also indicate, to the core network, that the holographic video call needs to be encrypted; for another example, when the first mobile terminal determines that the user of the first mobile terminal is a VIP (very important user), it may also indicate to the core network that the holographic video call needs to be encrypted.
In an embodiment of the present invention, to improve security, the method further includes:
and receiving shell updating period information sent by the core network, and periodically updating the shell data according to the updating period information, so that the shell of the holographic video can be periodically changed. Of course, the periodic variation may be a periodic variation in color, a periodic variation in shape, or a periodic variation in brightness, or a combination of these.
In the embodiment of the present invention, the change period may be 1 minute or 2 minutes, and certainly, in order to further save resources, the change period may also be 5 minutes, and the number of the update periods is not specifically limited.
The network architecture to which the method 10 applies may be as shown in fig. 1D, where fig. 1D may be further refined as shown in fig. 1E. In the scenario shown in fig. 1E, since a mobile terminal can establish multiple PDU sessions simultaneously, different PDU sessions are respectively served by different UPFs, that is, one SMF in the core network may control more than two UPFs, and if the encryption operation is placed in the SMF, it is impossible to distinguish between two UPFs, and therefore, information related to shell data needs to be placed in the UPF for management, such as update cycle information of the shell data. Specifically, after establishing session connection and completing a routing task, the SMF identifies an encryption identifier in a PDU session type parameter corresponding to the holographic video call, and if the encryption identifier indicates that the encryption identifier is used for encryption, sends an encryption request to a UPF corresponding to a session layer of the core network.
And after receiving the encryption request, the UPF corresponding to the first mobile terminal controls the routing skip, completes the establishment of the session, processes the received encryption request, generates shell updating period information, and sends the shell updating period information to the UPF of the second mobile terminal for message synchronization.
In this embodiment of the present invention, further, the UPF corresponding to the first mobile terminal may generate not only the shell update period information but also the shell identifier, so that when the execution main body of the method 10 obtains the shell data, the shell identifier sent by the UPF corresponding to the first mobile terminal may be used as a part factor of a random sequence corresponding to the shell data, where, for example, if the shell identifier a is 010110, the random sequence is a + 001110011F.
It is described above that the shell data needs to be updated after a fixed time period, however, in some cases, as the scene changes, the current shell may not have the effect of preventing others from seeing the holographic video, and therefore, in order to further improve the security, the method further includes:
receiving the rotation angle information of the second mobile terminal sent by the core network; judging whether the rotation angle reaches a threshold value;
and if the rotation angle is determined to reach the threshold value, updating the shell data.
That is, when it is determined that the rotation angle of the second mobile terminal reaches the threshold, at this time, the current shell may not prevent others from seeing the holographic video, and in order to improve security, further, the current shell data needs to be updated, and since the shell of the holographic video presented by the second mobile terminal is the updated shell, others can be prevented from seeing the holographic video.
The above description is for triggering the updating of the shell data according to the rotation angle, but of course, other triggering conditions, such as light intensity, are also possible and will not be described in detail here.
The shell data update can be a combination of the above update modes, and is not described in detail here.
In the embodiment of the invention, after the shell data is updated and the holographic video call data is subsequently received, the holographic video call data is processed by adopting the updated shell data, so that the shell of the holographic video presented at the second mobile terminal is the updated shell.
In this embodiment of the present invention, optionally, the shell data includes at least one of a color parameter, a shape parameter, a thickness parameter, and a size parameter.
If the color parameter is a parameter related to red, the shell presented by the second mobile terminal is red, the color parameter is a parameter related to gray, and the shell presented by the second mobile terminal is gray, or other colors may be used, which is not specifically limited herein.
Similarly, other parameters are not specifically limited, as long as the effect of preventing other people from seeing the holographic video can be achieved, and detailed description is omitted here.
In practical application, a scene where the second mobile terminal is located may be a scene with higher security, in order to improve user experience and improve flexibility, further, in the embodiment of the present invention, the execution main body of the method 10 may also receive a message of the second mobile terminal, where the message is used to indicate that encryption processing is not required, for example, when the second mobile terminal is located at home, the holographic video call data may be directly sent to the second mobile terminal, and the second mobile terminal presents a holographic video without a shell.
Similarly, the holographic video of the second mobile terminal may also be encrypted when the holographic video of the second mobile terminal is presented by the first mobile terminal, and at this time, the holographic video with the virtual 3D shell is presented by the first mobile terminal, and the processing procedure is similar to the procedure described above, and is not described in detail here.
In the above description, a scenario of establishing communication between the first mobile terminal and the second mobile terminal is described, and in practical applications, the first mobile terminal and the second mobile terminal may also stop communicating, at this time, after the holographic video call is suspended, and the core network receives an instruction to release the link, the execution main body of the method 10 stops generating shell data, and also stops processing the holographic video call data by using the shell data.
Referring to fig. 2, in an embodiment of the present invention, a holographic video call method 20 is provided, including:
step 200: receiving holographic video call data which are sent by a video server and comprise shell data;
step 210: and loading the image corresponding to the shell data around the image of other data to obtain the holographic video with the virtual 3D shell.
Optionally, the shell data is located before a start bit of valid information in the holographic video call data.
Optionally, the field in which the shell data is located may be located before the field in which the valid information in the holographic video call data is located, but not adjacent to the field in which the valid information in the holographic video call data is located, in the scenario shown in fig. 1B, the video corresponding to the invalid information in the holographic video call data presented in the second mobile terminal also has a shell. Thus, in the scenario shown in fig. 1B, there may be a problem of wasting resources, and in order to save resources, optionally, a field where the shell data is located before a field where the valid information in the holographic video call data is located, and is adjacent to the field, in the scenario shown in fig. 1C, in this scenario, a video corresponding to the invalid information in the holographic video call data presented in the second mobile terminal does not have a shell, and a video corresponding to the valid information in the holographic video call data presented in the second mobile terminal only has a shell, so that a problem of wasting resources may be avoided.
It should be noted that, in the embodiment of the present invention, it is only required to ensure that the field in which the shell data is located before the field in which the valid information in the holographic video call data is located, and a specific positional relationship is not further limited.
Optionally, the shell data comprises at least one of a color parameter, a shape parameter, a thickness parameter, and a size parameter.
If the color parameter is a parameter related to red, the shell to be presented is red, the color parameter is a parameter related to gray, and the shell to be presented is gray, or other colors may be used, which is not specifically limited herein.
Similarly, other parameters are not specifically limited, as long as the effect of preventing other people from seeing the holographic video can be achieved, and detailed description is omitted here.
Referring to fig. 3, in an embodiment of the present invention, a video server 30 is further provided, including:
a receiving unit 300, configured to receive holographic video call data sent by a first mobile terminal through a core network;
the processing unit 310 is configured to process the holographic video call data by using shell data;
a sending unit 320, configured to send the processed holographic video call data to a second mobile terminal through the core network, so that the second mobile terminal presents a holographic video with a virtual 3D shell.
In the embodiment of the present invention, further, both the first mobile terminal and the second mobile terminal need to register in the core network, so that the subsequent first mobile terminal and the second mobile terminal may interact with the core network, and the specific registration process may adopt the prior art, which is not specifically limited herein.
In the embodiment of the present invention, further, in order to improve security, before the first mobile terminal interacts with the core network, the core network needs to perform authentication on the first mobile terminal, and a specific authentication process may use a currently existing technology, which is not limited specifically herein.
In this embodiment of the present invention, the processing unit 310 is specifically configured to add the shell data to the beginning of the valid information in the holographic video call data.
In this embodiment of the present invention, if the processing unit 310 adds the shell data to the holographic video call data before the start bit of the valid information, the field where the shell data is located may be located before the field where the valid information is located in the holographic video call data, but is not adjacent to the field, in the scenario shown in fig. 1B, and the video corresponding to the invalid information in the holographic video call data presented in the second mobile terminal also has a shell. Thus, in the scenario shown in fig. 1B, there may be a problem of wasting resources, and in order to save resources, optionally, a field where the shell data is located before a field where the valid information in the holographic video call data is located, and is adjacent to the field, in the scenario shown in fig. 1C, in this scenario, a video corresponding to the invalid information in the holographic video call data presented in the second mobile terminal does not have a shell, and a video corresponding to the valid information in the holographic video call data presented in the second mobile terminal only has a shell, so that a problem of wasting resources may be avoided.
It should be noted that, in the embodiment of the present invention, it is only required to ensure that the field in which the shell data is located before the field in which the valid information in the holographic video call data is located, and a specific positional relationship is not further limited.
In the embodiment of the present invention, the shell data is obtained according to a shell generation instruction sent by the core network or is preset. That is to say, before the shell data is used to process the holographic video call data, the shell data is obtained first, and how to obtain the shell data specifically may be obtained in two ways, one is obtained according to an instruction of the core network, and the other is locally generated in advance, and it is not necessary to perform a generation operation according to an instruction of the core network.
In this embodiment of the present invention, when the shell data is obtained according to the shell generation instruction sent by the core network, the core network may trigger to execute an operation of sending the shell generation instruction according to a message of the first mobile terminal, for example, when the first mobile terminal sends a request for establishing a data session connection to the core network, the request carries an identifier indicating whether to encrypt, and the request for establishing a data session connection is as follows:
< PDU Session attribute > < Data network name > < PDU session type > < SSC MODE > < PDU session ID >
When the identifier is 1, the holographic video call needs to be encrypted, and when the identifier is 0, the holographic video call does not need to be encrypted. Of course, it may also be that when the identifier is 0, it indicates that the holographic video call needs to be encrypted, and when the identifier is 1, it indicates that the holographic video call does not need to be encrypted, which kind of identifier is used for indicating encryption, which kind of identifier is used for indicating that no encryption is performed, and no specific limitation is made herein; meanwhile, which field of the request the identifier is located in is not specifically limited, that is, as long as the request carries an identifier that can be recognized by the core network and is used for indicating whether to encrypt, which identifier is specifically located at which position, and which identifier is specifically used for indicating that the identifier is encrypted and unencrypted, which is not specifically limited in the embodiments of the present invention.
It has been described above that the request for establishing the data session connection carries an identifier indicating whether to encrypt, and in the embodiment of the present invention, optionally, a separate message may also be used to indicate whether the holographic video call needs to be encrypted to the core network, which is not limited herein.
In the embodiment of the present invention, whether the holographic video call between the first mobile terminal and the second mobile terminal needs to be encrypted may be determined according to a user instruction.
For example, when the first mobile terminal receives an instruction of performing a holographic video call with the second mobile terminal, an "encryption" option and an "non-encryption" option are presented in the interface, and after a user clicks the "encryption" option in the interface of the first mobile terminal, when the first mobile terminal sends a request for establishing a data session connection to the SMF, the request carries an encryption identifier.
Certainly, in order to improve user experience, in the embodiment of the present invention, the first mobile terminal may also indicate, to the core network, that the holographic video call needs to be encrypted when locally determining that the current user meets the encryption condition, for example, when the first mobile terminal determines that the user is in a relatively close identity relationship with the user of the second mobile terminal, such as "family", "coworkers", and the like, the first mobile terminal may also indicate, to the core network, that the holographic video call needs to be encrypted; for another example, when the first mobile terminal determines that the user of the first mobile terminal is the VIP, it may indicate to the core network that the holographic video call needs to be encrypted.
Further, the video server further includes an updating unit 330, wherein:
the receiving unit 300 is configured to receive the shell update cycle information sent by the core network;
the updating unit 330 is configured to periodically update the shell data according to the update period information.
In this way, the envelope of the holographic video may be changed periodically. Of course, the periodic variation may be a periodic variation in color, a periodic variation in shape, or a periodic variation in brightness, or a combination of these.
In the embodiment of the present invention, the change period may be 1 minute or 2 minutes, and certainly, in order to further save resources, the change period may also be 5 minutes, and the number of the update periods is not specifically limited.
The network architecture to which the present solution is applied may be as shown in fig. 1D, wherein fig. 1D may be further refined as shown in fig. 1E. In the scenario shown in fig. 1E, since a mobile terminal can establish multiple PDU sessions simultaneously, different PDU sessions are respectively served by different UPFs, that is, one SMF in the core network may control more than two UPFs, and if the encryption operation is placed in the SMF, it is impossible to distinguish between two UPFs, and therefore, information related to shell data needs to be placed in the UPF for management, such as update cycle information of the shell data. Specifically, after establishing session connection and completing a routing task, the SMF identifies an encryption identifier in a PDU session type parameter corresponding to the holographic video call, and if the encryption identifier indicates that the encryption identifier is used for encryption, sends an encryption request to a UPF corresponding to a session layer of the core network.
And after receiving the encryption request, the UPF corresponding to the first mobile terminal controls the routing skip, completes the establishment of the session, processes the received encryption request, generates shell updating period information, and sends the shell updating period information to the UPF of the second mobile terminal for message synchronization.
In this embodiment of the present invention, further, the UPF corresponding to the first mobile terminal may generate not only the shell update period information but also the shell identifier, so that when the video server 30 obtains the shell data, the shell identifier sent by the UPF corresponding to the first mobile terminal may be used as a part factor of a random sequence corresponding to the shell data, where for example, if the shell identifier a is 010110, the random sequence is a + 001110011F.
It is described above that the shell data needs to be updated after a fixed time period, however, in some cases, as the scene changes, the current shell may not have the effect of preventing others from seeing the holographic video, and therefore, in order to further improve the security, the video server further includes a determining unit 340 and an updating unit 330, wherein:
the receiving unit 300 is further configured to receive rotation information of the second mobile terminal sent by the core network;
the judging unit 340 is configured to judge whether the rotation information reaches a threshold;
the updating unit 330 is configured to update the shell data if the determining unit 340 determines that the rotation information reaches the threshold.
That is, when it is determined that the rotation angle of the second mobile terminal reaches the threshold, at this time, the current shell may not prevent others from seeing the holographic video, and in order to improve security, further, the current shell data needs to be updated, and since the shell of the holographic video presented by the second mobile terminal is the updated shell, others can be prevented from seeing the holographic video.
The above description is for triggering the updating of the shell data according to the rotation angle, but of course, other triggering conditions, such as light intensity, are also possible and will not be described in detail here.
The shell data update can be a combination of the above update modes, and is not described in detail here.
In the embodiment of the invention, after the shell data is updated and the holographic video call data is subsequently received, the holographic video call data is processed by adopting the updated shell data, so that the shell of the holographic video presented at the second mobile terminal is the updated shell.
In this embodiment of the present invention, optionally, the shell data includes at least one of a color parameter, a shape parameter, a thickness parameter, and a size parameter.
If the color parameter is a parameter related to red, the shell presented by the second mobile terminal is red, the color parameter is a parameter related to gray, and the shell presented by the second mobile terminal is gray, or other colors may be used, which is not specifically limited herein.
