Embodiment 2

FIG. 2 is a flowchart of a video sharing method provided in Embodiment 2 of the present invention. As shown in FIG. 2 , the video sharing method is implemented based on an application function entity, and the video sharing method includes:

Step 21: The application function entity receives a video sharing request sent by the first user terminal, where the video sharing request includes the user identifier of the second user terminal and the local first network information of the video stream to be shared in the terminal.

In this embodiment, before step 21, the first user terminal is currently playing a certain video stream, and the video server sends the data of the video stream to the data network gateway and the first user plane function entity corresponding to the first user terminal. the first user terminal.

In this embodiment, when the first user terminal needs to share the currently playing video stream to the second user terminal, the first user terminal first sends a video sharing request to an application function entity (Application Function, AF for short).

Step 22: The application function entity acquires the video playback parameters of the video stream currently played by the first user terminal and requested to be shared.

Specifically, the application function entity obtains the metadata of the video stream from the video server corresponding to the video stream, the metadata of the video stream includes the video playback parameters of the video stream, and the video playback parameters include but are not limited to: the video stream The encoding format, resolution, encoding rate, audio parameters, etc.

Step 23: The application function entity acquires the video playback capability parameter of the second user terminal.

Wherein, the application function entity interacts with the second user terminal through the core network to obtain video playback capability parameters of the second user terminal, and the video playback capability parameters of the second user terminal include but are not limited to: codec format, resolution, encoding rate, audio parameters, etc.

Step 24, the application function entity determines the routing information of the video stream to be shared based on the video playback parameters of the video stream to be shared and the video playback capability parameter of the second user terminal, and the target acquisition address in the routing information includes the first user plane. The entry address of the functional entity or the entry address of the video server.

The first user plane functional entity is a functional entity used to provide a video stream forwarding service to the first user terminal, and the video server is used to provide the first user plane functional entity with the video required by the first user terminal through the data network gateway. flow.

Specifically, step 24 includes:

Step 241: Determine whether the second user terminal has the playback capability of the video stream according to the video playback parameters of the video stream to be shared and the video playback capability parameter of the second user terminal.

Specifically, by judging whether the video playback capability parameter of the second user terminal matches the video playback parameter of the video stream to be shared, it is determined whether the second user terminal has the playback capability of the video stream. If it matches, it is determined that the second user terminal has the playback capability of the video stream; otherwise, it is determined that the second user terminal does not have the playback capability of the video stream. For example, if the video playback capability parameter of the second user terminal is the same as the video playback parameter of the video stream to be shared, that is, the codec format is the same, the resolution is the same, the encoding rate is the same, and the audio parameters are the same, it is determined that the two match, otherwise Mismatch.

Step 242: The application function entity sends a forwarding state configuration request of the video stream to be shared to the first user plane functional entity, so that the first user plane functional entity can modify the forwarding state of the video stream according to the forwarding state configuration request, and configure the The route of forwarding the video stream to the second user terminal at the same time.

In this embodiment, if the application function entity determines that the second user terminal has the playback capability of the video stream to be shared, the application function entity sends the to-be-shared video stream to the first user plane function entity for providing the forwarding service of the video stream. The forwarding state configuration request of the video stream, the request may include the session identifier of the video stream, the user identifier of the first user terminal, and the user identifier of the second user terminal, wherein the user identifier of the first user terminal can be based on the user identifier of the first user terminal. Video sharing request acquisition. The first user plane functional entity modifies the forwarding state of the video stream in response to the forwarding state configuration request from the application functional entity, and configures a route for simultaneously forwarding the video stream to the second user terminal.

Wherein, when the first user terminal and the second user terminal correspond to the same user plane functional entity, that is, the first user plane functional entity can provide corresponding services to the first user terminal and the second user terminal, the first user plane functional entity modifies the The forwarding state of the video stream is: the forwarding state of the video stream is changed from the forwarding state of only forwarding the video stream to the first user terminal to the forwarding state of the video stream to the first user terminal, while copying and forwarding the video stream to the first user terminal. the forwarding state of the same video stream to the second user terminal. In this case, configuring a route for simultaneously forwarding the video stream to the second user terminal includes: establishing a route from the first user plane functional entity to the second user terminal.

When the first user terminal and the second user terminal correspond to different user plane functional entities, that is, the first user terminal corresponds to the first user plane functional entity, and the second user terminal corresponds to the second user plane functional entity, then the first user plane functional entity Modifying the forwarding state of the video stream is: changing the forwarding state of the video stream from the forwarding state of only forwarding the video stream to the first user terminal, to modifying the forwarding state of the video stream to the first user terminal while copying a copy of the video stream. The same video stream is forwarded to the second user terminal through the second user plane functional entity. In this case, configuring a route for simultaneously forwarding the video stream to the second user terminal includes: establishing a route from the first user plane functional entity to the second user plane functional entity.

Step 243: The application function entity determines the routing information of the video stream to be shared in response to the forwarding state configuration success message of the first user plane function entity, where the routing information includes the entry address of the first user plane function entity, and jumps to Step 25.

In this embodiment, the first user plane functional entity modifies the forwarding state of the video stream and configures a route for simultaneously forwarding the video stream to the second user terminal in response to the forwarding state configuration request from the application functional entity, and then sends the application function The entity returns a forwarding status configuration success message.

When the first user terminal and the second user terminal correspond to different user plane functional entities, that is, the first user terminal corresponds to the first user plane functional entity, and the second user terminal corresponds to the second user plane functional entity, the configuration from the data network gateway to the The routing of the second user terminal includes establishing a route from the data network gateway to the second user plane functional entity.

Step 245: The application function entity sends a video generation request to the video server, so that the video server can generate a video stream with the same content as the video stream currently played by the first user terminal and satisfying the playback capability of the second user terminal according to the video generation request.

In this embodiment, if the application function entity determines that the second user terminal does not have the playback capability of the video stream to be shared, the application function entity further sends a video generation request to the video server, so that the video server can generate and match the video stream according to the video generation request. A video stream currently played by a user terminal has the same content and satisfies the playback capability of the second user terminal. The video generation request may include the session identifier of the video stream to be shared, the user identifier of the first user terminal, the user identifier of the second user terminal, the video playback capability parameter of the second user terminal, and the like.

The video stream with video playback capability, for example, generates a video stream with the same content as the video stream to be shared, and the resolution, codec format, coding rate, and audio parameters are consistent with the video playback capability parameters of the second user terminal. After the video server generates the corresponding video stream in response to the video generation request, the video server caches the video stream, waits for the request of the second user terminal, and responds to the request of the second user terminal, through the data network gateway, the second user terminal The corresponding user plane functional entity sends the video stream to the second user terminal.

Wherein, step 244 and step 245 may be executed simultaneously or sequentially, and the execution order is not limited.

Step 246: The application function entity determines the routing information of the video stream to be shared in response to the routing configuration success message of the data network gateway and the video generation success message of the video server, where the routing information includes the entry address of the video server, and jumps to Go to step 25.

Then, the application function entity executes step 246. In step 246, the entry address of the video server may be acquired by the application function entity in advance, or the entry address of the video server is carried in the video generation success message returned by the video server, or is obtained in other ways, which is not limited in this embodiment.

Step 25: The application function entity allocates the routing information of the video stream to be shared to the second user terminal, so that the second user terminal can request, acquire and play the video stream currently played and requested to be shared by the first user terminal according to the routing information.

The routing information includes a target acquisition address, and the second user terminal requests, acquires and plays the video stream currently played and requested to be shared by the first user terminal by accessing the target acquisition address.

Specifically, as mentioned above, in the case where the second user terminal has the playback capability of the video stream, the target acquisition address in the routing information of the video stream to be shared includes the entry address of the first user plane functional entity, then in step In step 25, after acquiring the routing information of the video stream allocated by the application functional entity, the second user terminal may request the first user plane functional entity to acquire the corresponding video stream through the entry address of the first user plane functional entity, and the first In response to the request, the user plane function entity copies and forwards a copy of the same video stream to the second user terminal while forwarding the video stream to the first user terminal according to the preconfigured route and the forwarding state corresponding to the video stream. , at this time, the second user terminal can acquire and play the video stream.

In the case where the second user terminal does not have the playback capability of the video stream, the target acquisition address in the routing information of the video stream to be shared includes the entry address of the video server, then in step 25, the second user terminal acquires the application After the routing information of the video stream is allocated by the functional entity, the video server can request the video server to obtain the corresponding video stream through the entry address of the video server. And the video stream that satisfies the video playback capability of the second user terminal is sent to the second user terminal through the data network gateway and the user plane function entity corresponding to the second user terminal. At this time, the second user terminal can obtain and play the corresponding video stream. .

Step 35: The application function entity initiates a call request for the second user terminal to the core network according to the user identifier of the second user terminal, wherein the call type is instant video sharing, and the call request includes the user identifier of the first user terminal.

Step 36: The application function entity receives a session establishment confirmation message sent by the core network based on the call request, where the session establishment confirmation message includes the video playback capability parameter of the second user terminal.

Specifically, in step 35, the application function entity transmits data to the second user terminal through the unified data management function entity (Unified Data Management, UDM for short) in the core network (for example, the 5G core network) according to the user identity of the second user terminal. A call request is initiated, and the unified data management function entity sends the call request to a second access and mobility management function entity (Access and Mobility Management Function, AMF for short) in the core network currently providing access services for the second user terminal.

In step 36, the application function entity receives the session establishment confirmation message sent by the core network based on the call request, including:

Step 361: Based on the call request, the second access and mobility management functional entity in the core network interacts with the second user terminal to obtain video playback capability parameters of the second user terminal.
