The following detailed description of various embodiments of the invention refers to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present invention only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
The first embodiment is as follows:
as shown in fig. 2, an embodiment of the present invention provides a video session establishment method, where the method includes:
s201, the gateway device receives a request message sent by the first device, wherein the request message is used for indicating the first device to request to establish a video session with the second device.
S202, when at least one end device in the first device and the second device has a voice function and does not have a video function, the gateway device determines as an auxiliary device matched with the at least one end device in advance.
S203, the gateway device establishes a video session between the first device and the second device, and in the process of the video session between the first device and the second device, the auxiliary device is used for displaying video data from the opposite device for the end device matched with the auxiliary device, and/or the auxiliary device is used for acquiring the video data of the end device matched with the auxiliary device.
The gateway device is at least one end device which has a voice function and does not have a video function and is matched with the auxiliary device in the first device and the second device, the video function of the at least one end device which has the voice function and does not have the video function in the first device and the second device is realized by the gateway device through the matched auxiliary device in the process of carrying out the video session between the first device and the second device, and then the gateway device can realize the establishment of the video session between the terminal devices which do not have the video function in the at least one end device.
In this embodiment, the auxiliary device includes a video playing device and/or a video capturing device. In the process of carrying out video session between the first device and the second device, the video playing device is used for displaying video data from the opposite device for the device at one end matched with the video playing device, and the video collecting device is used for collecting the video data of the device at one end matched with the video collecting device.
Optionally, before S202, the gateway device matches the auxiliary device for the at least one end device, and the method for the gateway device to match the auxiliary device for the at least one end device includes: the gateway device determines that at least one end device in the first device and the second device has a voice function and does not have a video function; and the gateway equipment matches the auxiliary equipment for the determined at least one end equipment and records the matching relation between the at least one end equipment and the auxiliary equipment matched for the at least one end equipment.
In this embodiment, the case where at least one of the first device and the second device has a voice function and does not have a video function includes the following three types:
in case one, the first device has a voice function and does not have a video function, and the second device has a voice function and a video function.
In case two, the first device has a voice function and a video function, and the second device has a voice function and does not have a video function.
Case three, the first device and the second device both have a voice function and no video function.
The establishment of a video session between the first device and the second device in any of the three situations can be realized by the video session establishment method shown in fig. 2.
The following describes the video session establishment method shown in fig. 2 in detail by taking as an example the case where the first device has a voice function and a video function, and the second device has a voice function and does not have a video function.
In S201, the gateway device receives a request message sent by the first device, where the request message is used to instruct the first device to request to establish a video session with the second device. The request message includes, but is not limited to, Session Description Protocol (SDP) information, which includes voice information and video information.
The video information is used for establishing a video data transmission link between the first device and the second device, and the voice information is used for establishing a voice data transmission link between the first device and the second device. The video information and the voice information include, but are not limited to, an Internet Protocol (IP) address of the first device, an IP address of the second device, a media type, a coding identification set, and the like. The IP address of the device may be a port number of the device; the media type refers to the type of data transmitted between the first device and the second device, that is, the media type in the video information is video data, and the media type in the voice information is voice data; the coding identifier set refers to a coding format of data transmitted between the first device and the second device, that is, the coding identifier set in the video information is a coding format of the video data, and the coding identifier set in the voice information is a coding format of the voice data.
Since the first device has a voice function and a video function, and the second device has a voice function and does not have a video function, the gateway device needs to determine an auxiliary device pre-matched to the second device in S202, so as to prepare for subsequently establishing a video session between the first device and the second device.
The auxiliary device is matched with the second device in advance by the gateway device, and comprises a video playing device and/or a video collecting device. The video playing device is used for displaying the video data from the first device for the second device in the process of video conversation between the first device and the second device. The video acquisition equipment is used for acquiring video data from the second equipment in the process of carrying out video conversation between the first equipment and the second equipment, and further transmitting the acquired video data to the first equipment for displaying.
Before the gateway device receives a request message sent by a first device and used for indicating the first device to request to establish a video session with a second device S201, or after the gateway device receives a request message sent by the first device and used for indicating the first device to request to establish a video session with the second device S201 and before the gateway device determines to be a pre-matched auxiliary device of the second device S202, the gateway device determines that the second device has a voice function and does not have a video function, the gateway device matches the auxiliary device for the second device, and records the matching relationship between the second device and the auxiliary device matched for the second device.
Therefore, the gateway device determines the auxiliary device pre-matched for the second device according to the recorded matching relationship in S202. The matching relationship recorded by the gateway device includes, but is not limited to, the identity of the second device, the identity of the auxiliary device matching the second device, and the matching relationship between the identity of the second device and the identity of the auxiliary device matching the second device. The identity of the secondary device matching the second device may be the IP address of the secondary device matching the second device.
In S202, the gateway device searches for an auxiliary device having a matching relationship with the second device in the recorded matching relationship of the second device, and detects whether the auxiliary device matching the second device is started. If the auxiliary equipment matched with the second equipment is started, the gateway equipment acquires the identifier of the auxiliary equipment matched with the second equipment from the recorded matching relation of the second equipment; if the auxiliary device matched with the second device is not started, the gateway device cannot acquire the identifier of the auxiliary device matched with the second device in the recorded matching relationship of the second device, which may cause that the video data transmission link between the first device and the auxiliary device matched with the second device cannot be established by the gateway device in the process of establishing the video session between the first device and the second device in S203, and further the video function of the second device cannot be realized by the auxiliary device matched with the second device by the gateway device in the process of performing the video session between the first device and the second device.
For example, if the video capture device matched with the second device is started, the gateway device obtains the IP address of the video capture device matched with the second device in the matching relationship of the second device; if the video acquisition device matched with the second device is not started, the IP address of the video acquisition device matched with the second device in the matching relationship of the second device is 0.0.0.0, and at this time, the gateway device cannot acquire the IP address of the video acquisition device matched with the second device.
Optionally, the gateway device may record a matching relationship between the second device and the auxiliary device matched for the second device by generating a matching relationship table. The matching relationship of the second device generated by the gateway device is shown in table 1.
TABLE 1
| Identification of the second device |
| IP address of video playing device matched for second device |
| IP address of video capture device matched for second device |
In this embodiment, the second device without the video function can be classified into the following three cases:
in the first case, the second device does not have a video capture function and a video playback function, and in this case, the gateway device includes a video capture device and a video playback device as an auxiliary device matched with the second device.
And in the second case, the second device has a video acquisition function but does not have a video playing function, and the gateway device is a video playing device which is an auxiliary device matched with the second device.
And in the third case, the second device does not have the video acquisition function but has the video playing function, and in this case, the gateway device is the video acquisition device as the auxiliary device matched with the second device.
In S203, in a case that the first device has a voice function and a video function, and the second device has the voice function and does not have the video function, the gateway device establishing the video session between the first device and the second device includes: the gateway device establishes a voice data transmission link between the first device and the second device, and the gateway device establishes a video data transmission link between the first device and an auxiliary device of the second device. In the process of performing a video session between the first device and the second device, the voice data transmission link is used for the gateway device to transmit the voice data acquired by one device of the first device and the second device to the opposite device through the voice data transmission link, the video data transmission link is used for the gateway device to transmit the video data acquired by the first device to the auxiliary device of the second device through the video data transmission link, and the gateway device transmits the video data acquired by the auxiliary device of the second device to the first device through the video data transmission link.
In the case that the first device has a voice function and a video function, and the second device has a voice function and does not have a video capture function and a video play function, the method for the gateway device to establish the video session between the first device and the second device in S203 includes the following steps:
the method comprises the following steps: because the first device has a voice function and a video function, the gateway device obtains that the video information a1 and the voice information B1 are carried in the SDP information of the request message sent by the first device.
The video information a1 includes the IP address of the first device, the IP address of the second device, the type of video data transmitted by the first device, and the encoding format of the video data transmitted by the first device. The voice information B1 includes the IP address of the first device, the IP address of the second device, the type of voice data transmitted by the first device, and the encoding format of the voice data transmitted by the first device.
Step two: the gateway device fills the IP address of the first device in the video information a1 into the transmission relationship of the second device, establishes a transmission link between the gateway device and the video playing device matched with the second device, and further establishes a video data transmission link between the first device and the video playing device matched with the second device.
If it is detected in S202 that the gateway device is not started for the video playing device matched with the second device, the gateway device will not establish a video data transmission link between the first device and the video playing device matched with the second device.
For example, a video data transmission link between the first device and the video playing device matched with the second device is established through a connection between the first device and a port number (Socket) in a User Datagram Protocol (UDP) in IP addresses of the video playing device matched with the second device. For another example, a video data Transmission link between the first device and the video playing device matched with the second device is established through Socket connection in a Transmission Control Protocol (CTP) in IP addresses of the first device and the video playing device matched with the second device.
Step three: the gateway device sends a voice data request message to the second device, where the SDP information of the voice data request message carries voice information B1. After receiving the voice data request message, the second device replies a voice data request response message to the gateway device, where the SDP information of the voice data request response message carries voice information B2.
Step four: the gateway device records the transmission relationship between the first device and the video acquisition device matched with the second device, and fills the IP address of the first device in the video information A1 into the transmission relationship of the second device. The gateway device establishes a transmission link between the gateway device and the video acquisition device matched with the second device, and then the gateway device establishes a second video data transmission link between the first device and the video acquisition device matched with the second device.
If the video acquisition equipment matched with the gateway equipment in advance for the second equipment is not started, the gateway equipment does not establish a video data transmission link between the first equipment and the video acquisition equipment matched with the second equipment.
Optionally, the gateway device may record the transmission relationship between the first device and the auxiliary device matched for the second device by generating a transmission relationship table. The transmission relationship of the second device generated by the gateway device is shown in table 2.
TABLE 2
Step five: after receiving the voice data request response message sent by the second device, the gateway device obtains the voice information B2 carried in the SDP information of the voice data request response message sent by the second device, and sends a request response message to the first device, where the SDP information of the request response message carries the voice information B2 and the video information a 2. And after receiving the request response message sent by the gateway equipment, the first equipment replies a response message to the gateway equipment. If the gateway device is not started for the video capture device matched with the second device, the SDP information of the request response message sent by the gateway device to the first device carries voice information B1.
