And step 12, distributing 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 which is currently played and requested to be shared by the first user terminal according to the routing information.
The video sharing method provided by the embodiment is used for responding to a video sharing request of a first user terminal, distributing routing information of a video stream to be shared to a second user terminal so that the second user terminal can request, acquire and play the video stream which is currently played and requested to be shared by the first user terminal according to the routing information, and the second user terminal can play the video stream shared by the first user terminal without installing a specific application or clicking a video link, so that the video sharing convenience is improved, and the user experience degree is also improved.
Example two
Fig. 2 is a flowchart of a video sharing method according to a second embodiment of the present invention, and 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 a user identifier of the second user terminal and first network information of the video stream to be shared in the local terminal.
In this embodiment, before step 21, the first user terminal currently plays a certain video stream, and the video server sends data of the video stream to the first user terminal through the data network gateway and the first user plane functional entity corresponding to the first user terminal.
In this embodiment, when a first user terminal needs to share a currently playing video stream to a second user terminal, the first user terminal first sends a video sharing request to an Application Function (AF).
Step 22, the application function entity obtains the video playing parameters of the video stream which is currently played and requested to be shared by the first user terminal.
Specifically, the application function entity obtains metadata of the video stream from a video server corresponding to the video stream, where the metadata of the video stream includes video playing parameters of the video stream, and the video playing parameters include, but are not limited to: the encoding format, resolution, encoding rate, audio parameters, etc. of the video stream.
And step 23, the application function entity acquires the video playing capability parameter of the second user terminal.
The application function entity interacts with the second user terminal through the core network to obtain the video playing capability parameter of the second user terminal, where the video playing capability parameter of the second user terminal includes but is not limited to: codec format, resolution, coding rate, audio parameters, etc.
And step 24, the application functional entity determines the routing information of the video stream to be shared based on the video playing parameter of the video stream to be shared and the video playing capability parameter of the second user terminal, wherein the target acquisition address in the routing information comprises the entry address of the first user plane functional entity or the entry address of the video server.
The first user plane functional entity is a functional entity for providing a forwarding service of a video stream to the first user terminal, and the video server is used for providing the video stream required by the first user terminal to the first user plane functional entity through the data network gateway.
Specifically, step 24 comprises:
step 241, determining whether the second user terminal has the playing capability of the video stream according to the video playing parameter of the video stream to be shared and the video playing capability parameter of the second user terminal, if so, executing step 242, otherwise, executing step 244.
Specifically, whether the second user terminal has the video playing capability is determined by judging whether the video playing capability parameter of the second user terminal is matched with the video playing parameter of the video stream to be shared. And if so, determining that the second user terminal has the playing capability of the video stream, otherwise, determining that the second user terminal does not have the playing capability of the video stream. For example, if the video playing capability parameter of the second user terminal is consistent with the video playing parameter of the video stream to be shared, that is, the encoding and decoding formats are consistent, the resolutions are consistent, the encoding rate is consistent, and the audio parameters are consistent, it is determined that the two are matched, otherwise, it is not matched.
Step 242, the application functional 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 modifies the forwarding state of the video stream according to the forwarding state configuration request, and configures a route for 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 playing capability of the video stream to be shared, the application function entity sends a forwarding state configuration request of the video stream to be shared to a first user plane function entity for providing a forwarding service of the video stream, where the request may include a session identifier of the video stream, a user identifier of the first user terminal, and a user identifier of the second user terminal, where the user identifier of the first user terminal may be obtained according to the video sharing request of the first user terminal. The first user plane functional entity responds to the forwarding state configuration request of the application 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.
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 forwarding state of the video stream, that is, the forwarding state of the video stream is: and changing the forwarding state of the video stream from the forwarding state of only forwarding the video stream to the first user terminal to the forwarding state of copying and forwarding the same video stream to the second user terminal while forwarding the video stream to the first user terminal. In this case, configuring a route for simultaneously forwarding the video stream to the second user terminal includes: a route is established 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, the forwarding state of the video stream modified by the first user plane functional entity is: and modifying the forwarding state of the video stream from the forwarding state of forwarding the video stream only to the first user terminal to the forwarding state of copying the same video stream and forwarding the same video stream to the second user terminal through the second user plane functional entity while forwarding the video stream to the first user terminal. In this case, configuring a route for simultaneously forwarding the video stream to the second user terminal includes: a route is established from the first user plane functional entity to the second user plane functional entity.
Step 243, the application functional 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 functional entity, where the routing information includes the entry address of the first user plane functional entity, and jumps to step 25.
In this embodiment, after responding to the forwarding state configuration request of the application function entity, the first user plane function entity modifies the forwarding state of the video stream and configures a route for simultaneously forwarding the video stream to the second user terminal, and then returns a forwarding state configuration success message to the application function entity. Then, the application function entity performs step 243, and in step 243, the entry address of the first user plane function entity may be obtained by the application function entity through pre-query, or may be obtained by the first user plane function entity through other manners, where the forwarding state configuration success message returned by the first user plane function entity carries the entry address of the first user plane function entity.
Step 244, the application function entity sends a route configuration request to the data network gateway, so that the data network gateway configures a route from the data network gateway to the second user terminal according to the route configuration request.
In this embodiment, if the application function entity determines that the second user terminal does not have the playing capability of the video stream to be shared, the application function entity sends a routing configuration request to a data network gateway for providing a forwarding service of the video stream, where the request may include a session identifier of the video stream, a user identifier of the first user terminal, and a user identifier of the second user terminal. The data network gateway configures a route from the data network gateway to the second user terminal in response to the route configuration request.
Specifically, when the first user terminal and the second user terminal correspond to the same user plane functional entity, configuring a route from the data network gateway to the second user terminal includes: a route is established from the data network gateway to the first user plane functional entity.
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, configuring a route from the data network gateway to the second user terminal includes: a route is established 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 generates a video stream which has the same content as the video stream currently played by the first user terminal and meets the playing 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 playing 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 generates, according to the video generation request, a video stream that has the same content as the video stream currently played by the first user terminal and that satisfies the playing capability of the second user terminal. The video generation request may include a session identifier of a video stream to be shared, a user identifier of the first user terminal, a user identifier of the second user terminal, a video playing capability parameter of the second user terminal, and the like.
In step 245, after receiving the video generation request of the application function entity, the video server generates a video stream that has the same content as the video stream and satisfies the video playing capability of the second user terminal, for example, a video stream that has the same content as the video stream to be shared and has resolution, codec format, encoding rate, and audio parameter that are consistent with the video playing capability parameter of the second user terminal, based on the session identifier of the video stream and the video playing capability parameter of the second user terminal. After responding to the video generation request, the video server generates a corresponding video stream, caches the video stream, waits for the request of the second user terminal, responds to the request of the second user terminal, and sends the video stream to the second user terminal through the data network gateway and the user plane functional entity corresponding to the second user terminal.
Step 244 and step 245 may be executed simultaneously or sequentially, and the execution order is not limited.
Step 246, the application functional entity determines the routing information of the video stream to be shared in response to the successful message of the routing configuration of the data network gateway and the successful message of the video generation of the video server, where the routing information includes the entry address of the video server, and jumps to step 25.
In this embodiment, after responding to the route configuration request of the application function entity and configuring the corresponding route, the data network gateway returns a route configuration success message to the application function entity; and after responding to the video generation request of the application functional entity to generate the corresponding video stream, the video server returns a video generation success message to the application functional entity. Then, the application function entity executes step 246, and in step 246, the entry address of the video server may be obtained by the application function entity through a pre-query, or may be obtained by the video server in a video generation success message returned by the video server, where the entry address carries the entry address of the video server, or may be obtained by other manners, which is not limited in this embodiment.
And 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 requests, acquires and plays the video stream which is currently played and requested to be shared by the first user terminal according to the routing information.
The second user terminal requests, acquires and plays the video stream which is currently played and requested to be shared by the first user terminal by accessing the target acquisition address.
Specifically, as described above, in a case that the second user terminal has the playing capability of the video stream, the destination obtaining 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 25, after the second user terminal obtains the routing information of the video stream allocated by the application functional entity, the second user terminal may request to obtain a corresponding video stream from the first user plane functional entity through the entry address of the first user plane functional entity, and the first user plane functional entity responds to the request, and copies and forwards an identical 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, where at this time, the second user terminal may obtain and play the video stream.
In the case that the second user terminal does not have the playing capability of the video stream, the destination obtaining address in the routing information of the video stream to be shared includes an entry address of the video server, then in step 25, after the second user terminal obtains the routing information of the video stream allocated by the application function entity, the second user terminal may request the video server to obtain a corresponding video stream through the entry address of the video server, and in response to the request, the video server sends the video stream, which is cached in advance, has the same content as the video stream to be shared and meets the video playing capability of the second user terminal, to the second user terminal through the data network gateway and the user plane function entity corresponding to the second user terminal, and at this time, the second user terminal may obtain and play the corresponding video stream.
According to the video sharing method provided by the embodiment, when a first user terminal needs to share a video which is currently played to a second user terminal, the first user terminal firstly sends a video sharing request to an application function entity, the application function entity responds to the video sharing request, determines routing information of the video to be shared, and distributes the routing information to the second user terminal, so that the second user terminal obtains and plays the video to be shared based on the routing information request.
EXAMPLE III
Fig. 3 is a flowchart of a video sharing method according to a third embodiment of the present invention, and as shown in fig. 3, the video sharing method includes:
step 31, the application function entity receives a video sharing request sent by the first user terminal, where the video sharing request includes a user identifier of the second user terminal and first network information of the video stream to be shared in the local terminal.
In this embodiment, the video server sends the Data of the video stream to the first User terminal through a Data Network gateway (DNGW, for short) and a User Plane Function (UPF, for short), where the first User terminal (UE, for short) is currently playing the video stream. When a first user terminal needs to share a currently playing video stream to a second user terminal, the first user terminal first sends a video sharing request to an Application Function (AF). The first user terminal may be a mobile terminal, such as a smart phone, a tablet computer, and the like, and the smart phone may be a 5G smart phone.
As an optional implementation manner, a video sharing client is pre-installed on a first user terminal, the first user terminal responds to an operation that a user calls the video sharing client when the first user terminal is currently playing a video stream, calls out and opens the video sharing client, and the video sharing client serves as a current system foreground application of the terminal; the step 21 specifically includes: and receiving a video sharing request sent by a user through a video sharing client. The first network information of the video stream to be shared in the local terminal is acquired from a previous system foreground application when the video sharing client is called out, the previous system foreground application is an application which is running on the terminal before the video sharing client is called out, namely the application for playing the video stream on the first user terminal.
As an optional implementation manner, the video sharing client pre-installed on the first user terminal is a dialing software system, the first user terminal currently plays a video stream, and when a user of the first user terminal needs to share the currently playing video stream, the first user terminal calls an operation of the dialing software system in response to that the user calls the dialing software system when the first user terminal currently plays the video stream, calls out the dialing software system, and enters a dialing interface of the dialing software system. For example, a user may call a preset operation list in a manner of pressing the interface for a long time on a playing interface of a video stream, and select an option for opening a dialing software system from the preset operation list, thereby triggering the call of the dialing software system, or the playing interface of the video stream is preset with a video sharing option, and the user automatically triggers the call of the dialing software system by clicking the video sharing option, thereby calling the dialing software system, or the user quits the playing interface of the current video stream, and directly opens the dialing software system on the first user terminal. It should be noted that, in this embodiment, the manner of invoking the dialing software system is not limited as long as the dialing software system can be invoked.
In the called dialing interface of the dialing software system, a user can input and dial a preset video sharing special number, or the preset video sharing special number is automatically generated when the dialing interface is called, so that the user can confirm whether to dial the number. When a user dials a preset video sharing special number through a dialing software system, a call request to an application function entity is triggered, the application function entity receives the call request of a first user terminal, and the call request is a video sharing request. The preset video sharing special number is a video sharing special number corresponding to the application function entity, and the video sharing request comprises a user identifier of the second user terminal and first network information of a video stream to be shared in the local terminal.
As an optional implementation manner, in response to a user dialing a preset video sharing dedicated number on the dialing interface, the dialing software system finds an application on a system foreground when the dialing software system is called to the system foreground of the terminal, where the previous application on the system foreground is an application of a video stream currently being played on the first user terminal, and obtains first network information of the video stream currently being played at the terminal local through the previous application on the system foreground.
The second user terminal may be a mobile terminal, such as a smart phone, a tablet computer, and the like, the smart phone may be a 5G smart phone, and the user identifier of the second user terminal may be a terminal number of the mobile terminal, such as a mobile phone number; the first network information of the video stream to be shared in the local terminal comprises a source port, a source address, a session identification of the video stream, a destination port and a destination address. The source port and the source address of the video stream in the local terminal are a port and an IP address corresponding to a Data Network Gateway (DNGW) for forwarding the video stream, the destination port and the destination address of the video stream in the local terminal are a port and an IP address corresponding to the first user terminal, and first network information of the video stream to be shared in the local terminal is acquired when the dialing software system is called out.
Optionally, the video sharing request includes first network information of the video stream to be shared locally at the terminal, and after the first user terminal sends the video sharing request, the first user terminal waits for a prompt of the application function entity and then inputs a user identifier of the sharing target, that is, the second user terminal. And the application function entity responds to the video sharing request, sends an input prompt of a sharing target to the first user terminal so that the first user terminal can input the user identification of the second user terminal according to the prompt, and the application function entity obtains the user identification of the second user terminal.
Step 32, the application function entity queries the source information of the video stream according to the first network information of the video stream to be shared in the local terminal, where the source information includes the second network information of the video stream in the corresponding data network gateway, the identifier of the first user plane function entity currently providing the forwarding service of the video stream for the first user terminal, and the identifier of the video server.
Specifically, the application function entity identifies a user identifier (for example, a mobile phone number of the first user terminal) of the first user terminal according to the calling information (for example, a calling number), and sends a query request of the source information to a Unified Data storage function entity (UDR), where the query request includes, but is not limited to: a user identification of the first user terminal and first network information of the video stream.
After receiving the query request of the application function entity, the unified data storage function entity queries an identifier of a first user plane function entity (UPF) that currently provides forwarding service for the video stream for the first user terminal according to the session identifier of the video stream and the user identifier of the first user terminal, where the identifier of the first user plane function entity (UPF) may be an entry address, that is, an access address, of the first user plane function entity (UPF). Then, the unified data storage functional entity queries second network information of the video stream in a data network gateway for forwarding the video stream according to the first network information, where a mapping relationship exists between the second network information and the first network information, and the second network information of the video stream in the corresponding data network gateway includes a source port, a source address, a session identifier of the video stream, a destination port, and a destination address. It can be understood that the source port and the source address of the video stream at the data network gateway are a port and an IP address corresponding to a video server for providing the video stream, and the destination port and the destination address of the video stream at the data network gateway are the port and the IP address corresponding to the data network gateway.
Meanwhile, the unified data storage functional entity queries an identifier of a video server for providing the video stream according to the source port and the source address of the video stream at the data network gateway, where the identifier may be an entry address of the video server, that is, an access address.
Step 33, the application functional entity sends an authentication request to the video server, where the authentication request includes the second network information of the video stream in the corresponding data network gateway.
Specifically, the application functional entity sends an authentication request to the video server corresponding to the identifier according to the identifier of the video server acquired in advance, so as to request the metadata corresponding to the video stream.
After receiving an authentication request of an application function entity, a video server authenticates the application function entity in response to the authentication request to check whether the application function entity subscribes a corresponding video sharing service to the video server or whether a protocol related to the video sharing service is agreed with the video server in advance, and when the video server checks that the application function entity subscribes the video sharing service, the authentication is successful, otherwise the authentication is failed. When the authentication fails, the video server returns an authentication failure message to the application function entity, and the application function entity returns a message of refusing to share the video to the first user terminal according to the authentication failure message, and the process is ended. When the authentication is successful, the video server returns an authentication success message to the application function entity, where the authentication success message includes the metadata of the video stream corresponding to the second network information, that is, step 34 is executed.
Optionally, after receiving the authentication request of the application function entity, the video server further authenticates the first user terminal in response to the authentication request to check whether the first user terminal has the right to share the video stream currently being played, if it is checked that the first user terminal has the corresponding right, the authentication is successful, otherwise, the authentication fails.
And step 34, the application function entity receives the metadata of the video stream sent by the video server after the authentication is passed.
The metadata of the video stream includes, but is not limited to: the video content name, video playing parameters, description information of a video source, description information of video content, a link address of the video, the generation time of the video and the like. The video playing parameters include, but are not limited to: the encoding format, resolution, encoding rate, audio parameters, playback duration, etc. of the video stream.
And step 35, the application function entity initiates a call request to 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.
And step 36, the application function entity receives a session establishment confirmation message sent by the core network based on the call request, wherein the session establishment confirmation message includes the video playing capability parameter of the second user terminal.
Specifically, in step 35, the application Function entity initiates a call request to the second user terminal through a Unified Data Management Function entity (UDM) in a core network (e.g. a 5G core network) according to the user identifier of the second user terminal, and the Unified Data Management Function entity sends the call request to a second Access and Mobility Management Function entity (AMF) currently providing an Access service for the second user terminal in the core network.
In step 36, the application function entity receives a session establishment confirmation message sent by the core network based on the call request, including:
step 361, the second access and mobility management functional entity in the core network interacts with the second user terminal based on the call request to obtain the video playing capability parameter of the second user terminal.
In step 361, the second access and mobility management functional entity, after recognizing that the call type of the call request is instant video sharing based on the call request, interacts with the second user terminal to obtain a video playing capability parameter of the second user terminal, where the video playing capability parameter of the second user terminal includes but is not limited to: codec format, resolution, coding rate, audio parameters, etc.
Step 362, the second access and mobility management functional entity determines a second session management functional entity corresponding to the second user terminal, and sends the video playing capability parameter of the second user terminal to the second session management functional entity.
In step 362, a second Session Management Function (SMF) is used for subsequent Session Management.
Step 363, the second session management functional entity determines a user plane functional entity corresponding to the second user terminal, and sends a session establishment confirmation message to the application functional entity, where the session establishment confirmation message includes the video playing capability parameter of the second user terminal.
Specifically, in step 363, the second session management function entity determines a user plane function entity (such as the second user plane function entity or the first user plane function entity) for providing the video data forwarding service for the second user terminal, and sends a session establishment confirmation message to the application function entity, where the session establishment confirmation message includes, but is not limited to: the video playing capability parameter of the second user terminal and the entry address (i.e. access address) of the user plane functional entity corresponding to the second user terminal, the user plane functional entity corresponding to the second user terminal may be the first user plane functional entity or the second user plane functional entity, and the first user plane functional entity and the second user plane functional entity are different user plane functional entities (UPFs).
And step 37, the application function entity determines the routing information of the video stream to be shared based on the video playing parameter of the video stream to be shared and the video playing capability parameter of the second user terminal.
The target obtaining address in the routing information to be shared includes an entry address of a first user plane functional entity or an entry address of a video server, the first user plane functional entity is a functional entity for providing a forwarding service of a video stream to a first user terminal, and the video server is used for providing the video stream required by the first user terminal, i.e. the video stream to be shared, to the first user plane functional entity through a data network gateway.
Specifically, for a detailed description of this step 37, reference may be made to the description of step 24 in the foregoing second embodiment, and details are not repeated here.
And step 38, the application function entity returns a session establishment success message to the core network based on the session establishment confirmation message of the core network, wherein the session establishment success message comprises the routing information of the video stream to be shared.
Specifically, after the application function entity receives the session establishment confirmation message of the second session management function entity in the core network and performs step 37 in step 36, in step 38, a session establishment success message is returned to the second session management function entity in the core network based on the session establishment confirmation message, where the session establishment success message includes but is not limited to: routing information of the video stream to be shared.
And step 39, the core network sends a ringing instruction to the second user terminal based on the session establishment success message of the application function entity, wherein the ringing instruction comprises the user identifier of the first user terminal, the call type and the routing information of the video stream to be shared.
Specifically, in step 39, after the second session management functional entity in the core network receives the session establishment success message of the application functional entity, if the user plane functional entity corresponding to the second user terminal is the second user plane functional entity, and the second user plane functional entity is different from the first user plane functional entity corresponding to the first user terminal, the second session management functional entity in the core network first notifies the second user plane functional entity to configure a route from the second user plane functional entity to the target acquisition address in the routing information, that is, establish a route from the second user plane functional entity to the first user plane functional entity or establish a route from the second user plane functional entity to the video server. And then, the second session management functional entity in the core network responds to the corresponding routing configuration success message of the second user plane functional entity, and sends the session establishment success message to the second access and mobility management functional entity in the core network. And the second access and mobile management functional entity in the core network responds to the session establishment success message and sends a ringing instruction to the second user terminal.
In step 39, after the second session management functional entity in the core network receives the session establishment success message of the application functional entity, if the user plane functional entity corresponding to the second user terminal is the first user plane functional entity (i.e. the user plane functional entity corresponding to the first user terminal), the first user plane functional entity does not need to configure a corresponding route, and the second session management functional entity in the core network directly sends the session establishment success message to the second access and mobility management functional entity in the core network. And the second access and mobile management functional entity in the core network responds to the session establishment success message and sends a ringing instruction to the second user terminal.
And step 40, the second user terminal rings in response to the ringing instruction and displays the video sharing prompt information on the terminal screen.
For example, the video sharing prompt message may be text message, such as "the user with user id xxx invites you to watch xxx video", and if the user id (mobile phone number) of the first user terminal exists in the preset address book of the second user terminal, the user id in the text message may be replaced with a corresponding name in the preset address book.
And step 41, the second user terminal responds to the answering operation of the user, acquires and plays the corresponding video stream according to the routing information request of the video stream to be shared, and ends the process.
In this embodiment, after the second user terminal rings, the user of the second user terminal can choose to listen or choose to refuse to listen, and when the user chooses to listen, step 41 is executed.
Specifically, as described above, in a case where the second user terminal has the playing capability of the video stream, the target obtaining address of the routing information of the video stream to be shared includes the entry address of the first user plane functional entity, then in step 41, the second user terminal requests the first user plane functional entity to obtain a corresponding video stream through the entry address of the first user plane functional entity according to the routing information of the video stream to be shared by responding to the answering operation of the user, and the first user plane functional entity copies and forwards an identical video stream to the second user terminal according to the preconfigured route and the forwarding state corresponding to the video stream while forwarding the video stream to the first user terminal, where at this time, the second user terminal can obtain and play the video stream.
In step 41, the second user terminal responds to the answering operation of the user, and requests the video server to acquire a corresponding video stream through the entry address of the video server according to the routing information of the video stream to be shared, and the video server responds to the request, and sends the video stream which is cached in advance, has the same content as the video stream to be shared and meets the video playing capability of the second user terminal to the second user terminal through the data network gateway and the user plane functional entity corresponding to the second user terminal, and at this time, the second user terminal can acquire and play the corresponding video stream.
After a period of time after the user selects answering, when the user selects hanging up, the second user terminal responds to the hanging up operation of the user and returns the hanging up message of the second user terminal to the second access and mobile management functional entity in the core network, the second access and mobile management functional entity sends a session termination instruction to the second session management functional entity, and the second session management functional entity interacts with the application functional entity to terminate the session. If the target acquisition address in the routing information comprises an entry address of a first user plane functional entity, the application functional entity responds to a message for terminating the session, and interacts with a unified data storage functional entity (UDR), a policy control functional entity (PCF), a first session management functional entity (SMF) corresponding to a first user terminal and the first user plane functional entity to terminate the video sharing; and if the target acquisition address in the routing information comprises the entry address of the video server, the application function entity responds to the message for terminating the session and interacts with the video server to terminate the video sharing.
When the user selects to reject answering, the second user terminal responds to the operation of rejecting answering of the user, and returns an answering rejection message to the application function entity through the core network, and the application function entity returns a message that the second user terminal rejects the video sharing invitation to the first user terminal. Specifically, the second user terminal responds to the answer rejection operation of the user, and returns an answer rejection message of the second user terminal to a second access and mobility management functional entity in the core network, the second access and mobility management functional entity sends a session termination instruction to a second session management functional entity, the second session management functional entity interacts with an application functional entity to terminate the session, and the application functional entity returns a message that the second user terminal rejects the video sharing invitation to the first user terminal based on the message that terminates the session. Meanwhile, if the target acquisition address in the routing information comprises an entry address of the first user plane functional entity, the application functional entity responds to the message for terminating the session, and interacts with a unified data storage functional entity (UDR), a policy control functional entity (PCF), a first session management functional entity (SMF) corresponding to the first user terminal and the first user plane functional entity to terminate the video sharing; and if the target acquisition address in the routing information comprises the entry address of the video server, the application function entity responds to the message for terminating the session and interacts with the video server to terminate the video sharing.
As an alternative embodiment, the video stream currently being played by the first user terminal is a video stream stored locally, and the local file system of the first user terminal is a video server.
According to the video sharing method provided by the embodiment, when a first user terminal needs to share a video which is currently played to a second user terminal, the first user terminal firstly sends a video sharing request to an application function entity, the application function entity responds to the video sharing request, determines routing information of the video to be shared, and distributes the routing information to the second user terminal, so that the second user terminal obtains and plays the video to be shared based on the routing information request.
