All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In some communication scenarios, a network device may provide network services to multiple media devices and receiving devices. There may be data transmission from one media device to one receiving device, or there may be data transmission from multiple media devices to one receiving device. In the data transmission from a plurality of media devices to a receiving device, there may be data transmission initiated simultaneously, or data transmission initiated successively but with crossed transmission time. When the network resources required by the data to be transmitted simultaneously exceed the maximum resources that can be provided by the network device, a part of the data needs to be transmitted in a delayed mode or cancelled. In the prior art, in the case of such a situation, network resource allocation and transmission are generally performed in the order of data transmission request initiation. And queuing the excessive requests, and sending the requests after spare resources are available.
The inventor finds that in the implementation of the scheme of the present application, some data with higher importance may be sent with delay or even cancelled in the prior art, which causes untimely data transmission. Therefore, the present application provides a data transmission method, system, network device, media device, and receiving device, wherein the importance of data is used as a determining condition for the data transmission sequence.

As shown in fig. 1, the media device 101 is sending media data information to the receiving device 103 through the network device 104 and has occupied all network resources. The media device 102 also initiates a data transfer request in an attempt to send more important media data information to the receiving device 103 via the network device 104. After the network device 104 determines the importance of the media data sent by the media device 101 and the importance of the media data to be sent by the media device 102, it determines to stop the data transmission of the media device 101, and to transmit the media data to be sent by the media device 102. The media devices 101 and 102 may be terminal devices having image capturing and/or image processing functions, such as monitoring devices; the receiving device 103 may be a server, a computer, a mobile phone, or other terminal device; network device 104 may be a server. Specific implementations can be found in the following examples.
Fig. 2 is a flowchart of a data transmission method according to an embodiment of the present application, and as shown in fig. 2, the method according to the embodiment includes:
s201, the network equipment receives a data transmission request, wherein the data transmission request comprises a data transmission priority corresponding to the media data to be transmitted.
The data transmission request is used for requesting the media device to send the media data to the network device, so that the network device forwards the media data to the receiving device.
The data transmission request can be sent to the network device by the media device or the control device.
A data transmission priority, related to an attribute of the media data to be transmitted. The higher the importance of the data transmission priority.
S202, the network equipment judges whether the media data to be transmitted meet the transmission condition according to the data transmission priority, and if so, the network equipment sends data transmission request feedback information to the media equipment.
The data transmission request feedback information is used for instructing the media device to send the media data.
The network device needs to determine whether the media data to be transmitted satisfies the transmission condition according to the data transmission priority of the media data to be transmitted and by combining the current network condition, so as to determine the transmission mode of the media data to be transmitted.
The setting criterion of the transmission condition may be to ensure the maximum transmission amount on the premise that media data with high priority is preferentially transmitted. The corresponding transmission condition may be that the amount of the remaining resources of the current network channel is sufficient to transmit the media data to be transmitted; or, the current network channel residual resource amount is not enough to transmit the media data to be transmitted, but the data transmission priority of the media data to be transmitted is higher than that of at least one path of media data currently being transmitted.
In some embodiments, if the network device determines that the media data to be transmitted does not satisfy the transmission condition, the network device may feed back information to the device that initiated the request to prompt that the media data to be transmitted does not satisfy the transmission condition, and initiate the data transmission request again after a certain length of time. Or the network device may wait for a certain duration until the network device determines that the media data to be transmitted satisfies the transmission condition, and then send data transmission request feedback information to the media device.
S203, the network equipment receives the media data sent by the media equipment according to the data transmission request feedback information.
S204, the network equipment sends the media data to the receiving equipment.
And after the media equipment sends the media data according to the data transmission request feedback information, the network equipment receives and forwards the media data.
The data transmission method provided by the application comprises the following steps: the network equipment receives a data transmission request, wherein the data transmission request comprises a data transmission priority corresponding to the media data to be transmitted; the data transmission request is used for requesting the media device to send media data to the network device so that the network device forwards the media data to the receiving device; the network equipment judges whether the media data to be transmitted meet the transmission condition or not according to the data transmission priority, if so, the network equipment sends data transmission request feedback information to the media equipment, and the data transmission request feedback information is used for indicating the media equipment to send the media data; the network equipment receives media data sent by the media equipment according to the data transmission request feedback information; the network device sends the media data to the receiving device. According to the scheme, the priority information of the data to be transmitted is added in the data transmission request, so that the network equipment can analyze the transmission sequence of the corresponding media data to be transmitted according to the priority information, and the communication efficiency is improved.
In some embodiments, the network device further needs to forward the received media data to the receiving device.
Specifically, the network device may determine a data transmission policy according to the data transmission priority; and the network equipment sends the media data to the receiving equipment according to the data sending strategy.
The data transmission policy refers to a policy that the network device transmits all current media data including media data to be transmitted to the receiving device. Similar to the setting criteria of the transmission conditions described above, the setting criteria of the data transmission policy may be such that the maximum transmission amount is ensured on the premise that media data with a high priority is preferentially transmitted. The corresponding sending strategy can be sequentially sent from high to low according to the priority order, and can also be sent by time-sharing combination of multiple paths of data.
In some embodiments, prior to determining the data transmission policy, the network device determines a data reception mode based on network conditions; the network equipment sends a data transmission notice to the receiving equipment according to the data receiving mode; the network equipment acquires a data receiving request sent by the receiving equipment; the data reception request is transmitted when the reception device determines to receive the media data after receiving the data transmission notification.

In the negotiation receiving mode, after receiving the data transmission notification, the receiving device outputs a prompt message for soliciting the user's opinion, and after detecting the instruction that the user agrees to receive, the receiving device determines to receive the media data and sends a data receiving request. Thus, the two modes differ primarily in whether selected by the user.
The beneficial effect of setting the data receiving mode is that when the network condition is good and the network resource is sufficient, the media device can directly receive the data; and when the network condition is poor or the network resources are in shortage, the selection can be made by the user. The choice can be made by the user, and the use feeling of the user is improved.
In some embodiments, before the network device sends the media data to the receiving device, the method further comprises: and the network equipment sends data receiving request feedback information to the receiving equipment according to the data sending strategy, wherein the data receiving request feedback information is used for prompting the data sending strategy.
The data reception request feedback information may include information indicative of a data transmission policy. For example, information such as the time of data transmission may be included.
The data reception request feedback information has an advantageous effect in that a user is given a prompt before receiving data. The user can master the key information of the data transmission process in advance, and the user experience is improved.
In some embodiments, the network device may further send a data transmission end prompt to the receiving device for a certain time before the end of data transmission according to information such as time of data transmission in the data sending policy, so that the receiving device generates and outputs the data transmission end prompt information; the network device then stops sending media data to the receiving device.
The end of data transmission prompt has the beneficial effect that the user is prompted before the end of data transmission. The user can master the data transmission process in advance, and the user experience is improved.
In some embodiments, the network device may also send a data transmission prompt to the media device after sending the media data to the receiving device, the data transmission prompt indicating that the media data has been sent to the receiving device. After receiving the prompt message, the media device can adaptively adjust its subsequent execution steps.
