Fig. 1 shows a schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present invention can be applied.
As shown in fig. 1, the system architecture may include a vehicle terminal 101 (the vehicle terminal 101 is provided with a device for capturing video, such as a drive recorder), a base station 102, an MEC (Mobile Edge Computing) server 103, an S/P-GW (Serving/Packet Data Network-Gateway) 104, a background cloud server 105, and a video pre-processing server 106. The vehicle terminal 101 communicates with the base station 102 through a Uu interface, the P-GW communicates with the background cloud server through an SGI interface, and the video preprocessing server 106 transmits video data to the background cloud server 105 through a network.
In one embodiment of the invention, the MEC server 103 and the video pre-processing server 106 constitute an edge data center that constitutes an edge computing facility of the mobile network. The MEC server 103 is deployed between the base station 102 and a core network device (S/P-GW) of the mobile network. The video preprocessing server 106 is deployed in an edge data center, and a background cloud server 105 located in a centralized data center is connected with core network equipment of the mobile network through an SGI interface. Wherein, the server responsible for road data acquisition is deployed in the background cloud server 105. The edge data center is provided with an interface for connecting the Internet and can be communicated with the background cloud server 105.
In an embodiment of the present invention, the vehicle terminal 101 may send a DNS query request to the MEC server 103 through the base station 102, after receiving the DNS query request sent by the vehicle terminal 101, the MEC server 103 replaces a source network address of the DNS query request with a network address of the MEC server 103 to obtain a processed DNS query request, and then sends the processed DNS query request to a DNS server (the DNS server may be a part of the background cloud server 105 shown in fig. 1), so that the DNS server may determine, according to the network address of the MEC server 103, the video preprocessing server 106 that receives the video data uploaded by the vehicle terminal 101, and return DNS response information including the network address of the video preprocessing server 106 to the MEC server 103. The MEC server 103 returns the network address of the video preprocessing server 106 to the vehicle terminal 101, and the vehicle terminal can actively upload video data to the video preprocessing server 106, or upload video data to the video preprocessing server 106 according to a capture instruction of the video preprocessing server 106. After receiving the video data uploaded by the vehicle terminal 101, the video preprocessing server 106 may preprocess the video data, for example, filter out unclear video data, and finally upload the preprocessed video data to the background cloud server 105 for storage.
In an embodiment of the present invention, the vehicle terminal 101 may send an HTTP (Hyper Text Transfer Protocol) message to the MEC server 103 through the base station 102, after receiving the HTTP message sent by the vehicle terminal 101, the MEC server 103 determines, according to the HTTP message, the video preprocessing server 106 that receives the video data uploaded by the vehicle terminal 101, further, the MEC server 103 replaces a destination address of the HTTP message with a network address of the video preprocessing server 106 to obtain a processed HTTP message, and then sends the processed HTTP message to the video preprocessing server 106. The video preprocessing server 106 may obtain the video data uploaded by the vehicle terminal 101 according to the HTTP message, and may send a capture instruction to the vehicle terminal 101 to obtain the video data uploaded by the vehicle terminal 101. After the video preprocessing server 106 obtains the video data uploaded by the vehicle terminal 101, the video data may be preprocessed, for example, to filter out unclear video data, and finally, the preprocessed video data is uploaded to the background cloud server 105 for storage.
It should be noted that, in the embodiment shown in fig. 1, the vehicle terminal 101 is taken as an example to be explained, and in other embodiments of the present invention, the video uploading party may also be other devices, such as a security monitoring camera, a mobile camera, and the like.
The implementation details of the technical scheme of the embodiment of the invention are explained in detail as follows:
fig. 2 schematically shows a flowchart of an uploading method of video data according to an embodiment of the present invention, which may be performed by a server, which may be the MEC server shown in fig. 1. Referring to fig. 2, the method for uploading video data at least includes steps S210 to S240, which are described in detail as follows:
in step S210, if a DNS query request sent by a video uploading party is received, replacing a source network address of the DNS query request with a network address of a target server to obtain a processed DNS query request.
In an embodiment of the present invention, the video uploading party may be a car data recorder, a security monitoring camera, a mobile camera, an intelligent mobile device (such as a smart phone and a tablet computer), and the like.
In an embodiment of the present invention, the source network address of the DNS query request is a network address of the video uploading party, and the network address may be an IP (Internet Protocol) address; the network address of the target server is the network address of the execution subject of the technical solution of the embodiment shown in fig. 2, and the network address may also be an IP address.
In an embodiment of the present invention, because the DNS query requests sent by the video uploading party are not all used for acquiring the network address of the video server, after receiving the DNS query request sent by the video uploading party, the target server may detect whether a domain name included in the DNS query request matches a domain name corresponding to a preset video server, and when detecting that the domain name included in the DNS query request matches a domain name corresponding to a preset video server, replace the source network address of the DNS query request with the network address of the target server.
Continuing to refer to fig. 2, in step S220, the processed DNS query request is sent to a DNS server, so that the DNS server determines, according to the network address of the target server, a video server that receives video data uploaded by the video uploading party, where the video server is configured to pre-process the video data uploaded by the video uploading party and transmit the pre-processed video data to a designated device.
In an embodiment of the present invention, the DNS server may determine, based on the correspondence between the network addresses, a video server that receives video data uploaded by the video uploading party according to the network address of the target server. Alternatively, the DNS server may prestore a correspondence between the network address of each target server and the network address of the corresponding video server, where the correspondence may be determined according to the distance, for example, the network address of the video server closer to each target server is associated with the network address of each target server.
In an embodiment of the present invention, the DNS server may also determine, according to the network address of the target server, a video server with a distance within a predetermined range and a low processing load as a video server that receives video data uploaded by the video uploading party.
In an embodiment of the present invention, the video server may filter out unclear video data, repeated video data, and practically irrelevant video data (e.g., road sign data is actually needed, so that non-road sign data may be filtered out) in the video data, which is uploaded by the video uploading party.
Continuing to refer to fig. 2, in step S230, DNS response information including the network address of the video server returned by the DNS server is received.
In step S240, the network address of the video server is returned to the video uploading party, so that the video uploading party uploads the video data to the video server through the network address of the video server.
In an embodiment of the present invention, the process of returning the network address of the video server to the video uploading party in step S240 may include: and replacing the destination network address of the DNS response information with the network address of the video uploading party to obtain the processed DNS response information, and then returning the processed DNS response information to the video uploading party.
The technical solution of the embodiment shown in fig. 2 is to explain the uploading method of video data of the embodiment of the present invention from the perspective of a target server (e.g., the MEC server shown in fig. 1), and the uploading method of video data of the embodiment of the present invention is further explained from the perspective of a video uploading party in conjunction with fig. 3.
Fig. 3 schematically shows a flowchart of an uploading method of video data, which may be performed by a video uploading party, such as the vehicle terminal shown in fig. 1, according to an embodiment of the present invention. Referring to fig. 3, the method for uploading video data at least includes steps S310 to S330, which are described in detail as follows:
in step S310, a DNS query request is sent to a target server, so that the target server sends the DNS query request to a DNS server and obtains DNS response information including a network address of a video server returned by the DNS server, where the video server is configured to pre-process video data uploaded by the video uploading party and transmit the pre-processed video data to a designated device.
In an embodiment of the present invention, the DNS query request sent by the video uploading party includes a domain name of the video server, so that it is convenient for the DNS server to determine that the DNS query request is a query request for acquiring a network address of the video server.
In step S320, the network address of the video server returned by the target server is received.
In an embodiment of the present invention, the target server may replace the destination network address of the received DNS response information returned by the DNS server with the network address of the video uploading party, obtain the processed DNS response information, and then return the processed DNS response information to the video uploading party.
In step S330, the video data is uploaded to the video server according to the network address of the video server.
In an embodiment of the present invention, the process of uploading the video data to the video server according to the network address of the video server in step S330 may specifically include the following two embodiments:
example 1:
the video uploading party uploads the acquired video data to the video server periodically according to the network address of the video server, namely, the video uploading party can actively upload the acquired video data.
Example 2:
the video uploading party can send the state information of the obtained video data to the video server according to the network address of the video server, and when a video obtaining request sent by the video server is received, the video data corresponding to the video obtaining request is uploaded to the video server, namely, the video server actively captures the video from the video uploading party.
In the technical solutions of the embodiments shown in fig. 2 and fig. 3, on one hand, the DNS server allocates a suitable video server to the video uploading party to reduce transmission delay of video data and improve uploading efficiency of video data, and on the other hand, since the network address of the target server replaces the source network address of the DNS query request and the video server is allocated according to the network address of the target server, the problem that the video server is difficult to capture a video actively due to the fact that the network address of the video uploading party is not fixed can also be avoided.
Fig. 4 schematically shows a flowchart of an uploading method of video data according to an embodiment of the present invention, which may be performed by a server, which may be the MEC server shown in fig. 1. Referring to fig. 4, the method for uploading video data at least includes steps S410 to S440, which are described in detail as follows:
in step S410, a data packet sent by the video uploading party is received.
In an embodiment of the present invention, the data packet sent by the video uploading party may be an HTTP packet, and the data packet may include video data uploaded by the video uploading party, for example, the video uploading party may periodically send the obtained video data in the form of a data packet.
In an embodiment of the present invention, the data packet sent by the video uploading party may also not include video data, but only include status information of the video data, where the status information may be an acquisition condition (such as an acquisition location, an acquisition duration) of the video data, and the like. In this case, when video acquisition information sent by the video server according to the video data state information is received, the video acquisition information may be sent to the video uploading party, and the video uploading party may upload corresponding video data based on the video acquisition information.
In step S420, a video server for receiving the video data uploaded by the video uploading party is determined according to the data packet, and the video server is configured to pre-process the video data uploaded by the video uploading party and transmit the video data to a designated device.
In an embodiment of the present invention, the video server that receives the video data uploaded by the video uploading party may be determined according to the network address included in the data packet based on the correspondence relationship between the network addresses. For example, a video server with a short distance is allocated to receive the video data uploaded by the video uploading party, or a video server with a short distance within a predetermined range and a low processing load is allocated to receive the video data uploaded by the video uploading party.
In an embodiment of the present invention, since the data packets sent by the video uploading party are not all related to transmitting video data, after receiving the data packets sent by the video uploading party, it may be detected whether the data packets include predetermined host information and search PATH information of the device executable file, and when detecting that the data packets include the predetermined host information and the search PATH information of the device executable file, a video server for receiving the video data uploaded by the video uploading party is determined according to the data packets.
In step S430, the destination address of the data packet is replaced with the network address of the video server, so as to obtain a processed data packet.
In one embodiment of the invention, the network address of the video server may be an IP address.
In step S440, the processed data packet is sent to the video server, so that the video server obtains the video data uploaded by the video uploading party based on the data packet.
In an embodiment of the present invention, if the data packet includes video data, the video server may obtain the video data from the data packet; if the data message only contains the video data state information, the video server can send a video data acquisition request according to the video data state information, and then the video uploading party can upload corresponding video data accordingly.

Meanwhile, the video server is used for preprocessing the video data uploaded by the video uploading party and then transmitting the preprocessed video data to the designated equipment (such as a background cloud server), so that the video server can filter useless data, the data amount transmitted to the designated equipment is reduced, and the consumption of network resources can be further saved.
The implementation details of the technical scheme of the embodiment of the invention are elaborated in detail by taking a vehicle event data recorder as a video uploading party, an MEC server as a target server and a video preprocessing server as a video processor as follows:
in the embodiment of the present invention, the car event data recorder may actively upload video data to the video preprocessing server, or the video preprocessing server actively captures video data from a driving record, which is described in different embodiments below.
Embodiment 1 of vehicle event data recorder actively uploading video data：
Referring to fig. 5, a method for uploading video data according to an embodiment of the present invention includes the following steps:
step S501, the automobile data recorder sends a DNS query request to the MEC server, where the DNS query request may be a UDP (User Datagram Protocol) message with a destination port of 53.
Step S502, after receiving the DNS query request, the MEC server detects the DNS query request, and if it is detected that the DNS query request includes a predetermined domain name (e.g., < bucktname > - < APPID >. cos. < Region >. myqcloud. com), performs a dyeing process, that is, replaces the source IP address of the DNS query request with the address of the MEC server.
In one embodiment of the present invention, the dyeing process in step S502 is implemented in a NAPT (network address Port Translation) based manner. Specifically, the MEC server replaces the source IP address in the DNS query request with the outer network address of the MEC server and replaces the source port number of the DNS query request with the locally unique port number of the MEC server. Meanwhile, the MEC server may locally record the mapping relationship so as to perform a reverse mapping operation on subsequent DNS responses from the intelligent DNS server.
In another embodiment of the present invention, the MEC server may further perform the coloring process on the DNS query request sent by the automobile data recorder in the form of a transparent proxy server, and detect all traffic between the radio access network and the radio core network in a transparent proxy manner.
In step S503, after processing the DNS query request, the MEC server forwards the DNS query request to the intelligent DNS server.
Step S504, a mapping relationship between the network address of the MEC server and the network address of the video preprocessing server is established in the IP address library of the intelligent DNS server. Therefore, when the intelligent DNS server receives the DNS query request with the source IP address being the external network address of the MEC server, the address of the video preprocessing server is returned in the DNS response.
In one embodiment of the invention, if the intelligent DNS server does not find the network address of the video pre-processing server corresponding to the outer network address of the MEC server, a default background server address may be returned in the DNS response.
In step S505, the intelligent DNS server returns a DNS response to the MEC server.
In step S506, after receiving the DNS response, the MEC server replaces the destination IP address of the DNS response with the address of the automobile data recorder.
In step S507, the MEC server sends the processed DNS response to the event data recorder.
Step S508, after receiving the DNS response, the event data recorder acquires the network address of the video preprocessing server, and then may initiate an HTTP connection to the video preprocessing server, and upload the video by the PUT method.
In an embodiment of the present invention, the automobile data recorder may upload the video to the video preprocessing server at regular time, for example, every 30 minutes, and this process may be automatically implemented by the automobile data recorder without intervention of the vehicle user.
Embodiment 2 of the automobile data recorder actively uploading video data：
Referring to fig. 6, a method for uploading video data according to an embodiment of the present invention includes the following steps:
step S601, the automobile data recorder sends an HTTP request message (the HTTP request message includes video data to be uploaded) to the MEC server, where the HTTP request message may be a TCP message with a destination port of 80.
Step S602, after receiving the HTTP request message sent by the automobile data recorder, the MEC server detects the HTTP request message from the automobile data recorder, and if the MEC server detects that the HTTP request message includes predetermined Host information (e.g., < bucktname > - < APPID >. cos. < Region >. myqcloud. com) and PATH information (/ < ObjectName >), replaces the destination IP address of the HTTP request message with the address of the video preprocessing server.
In one embodiment of the present invention, the MEC server in step S602 may process the HTTP request packet forwarded to the video pre-processing server in the form of a reverse transparent proxy. Specifically, the MEC server replaces the destination IP address of the HTTP request message with the IP address of the video preprocessing server, and records the direct correspondence between the source IP address and the source port number of the corresponding HTTP request message and the original destination IP address, namely < (source IP, source port), destinationIP >.
Step S603, the MEC server forwards the processed HTTP request packet to the video pre-processing server.
In step S604, the video preprocessing server sends HTTP response information to the MEC server, where the HTTP response information may include the receiving condition of the video data and the like.
Step S605, after receiving the HTTP response information sent by the video preprocessing server, the MEC server replaces the source IP address of the HTTP response information with the destination IP address of the HTTP request message according to the correspondence recorded in advance.
Step S606, the MEC server forwards the processed HTTP response information to the automobile data recorder.
Example 1 where video preprocessing Server actively grabs video data from Driving record：
Referring to fig. 7, a method for uploading video data according to an embodiment of the present invention includes the following steps:
in step S701, the automobile data recorder sends a DNS query request to the MEC server, where the DNS query request may be a UDP packet with a destination port of 53.
In step S702, after receiving the DNS query request, the MEC server detects the DNS query request, and if it is detected that the DNS query request includes a predetermined domain name (e.g., < bucktname > - < APPID >. cos. < Region >. myqcloud. com), performs a dyeing process, that is, replaces the source IP address of the DNS query request with the address of the MEC server.
In one embodiment of the present invention, the step S702 is implemented in a NAPT-based manner when performing the staining process. Specifically, the MEC server replaces the source IP address in the DNS query request with the outer network address of the MEC server and replaces the source port number of the DNS query request with the locally unique port number of the MEC server. Meanwhile, the MEC server may locally record the mapping relationship so as to perform a reverse mapping operation on subsequent DNS responses from the intelligent DNS server.
In step S703, the MEC server forwards the DNS query request to the intelligent DNS server after processing the DNS query request.
Step S704, a mapping relationship between the network address of the MEC server and the network address of the video preprocessing server is established in the IP address library of the intelligent DNS server. Therefore, when the intelligent DNS server receives the DNS query request with the source IP address being the external network address of the MEC server, the address of the video preprocessing server is returned in the DNS response.
In one embodiment of the invention, if the intelligent DNS server does not find the network address of the video pre-processing server corresponding to the outer network address of the MEC server, a default background server address may be returned in the DNS response.
In step S705, the intelligent DNS server returns a DNS response to the MEC server.
In step S706, after receiving the DNS response, the MEC server replaces the destination IP address of the DNS response with the address of the automobile data recorder.
In step S707, the MEC server sends the processed DNS response to the event data recorder.
Step S708, after receiving the DNS response, the event data recorder acquires the network address of the video preprocessing server, and then may initiate an HTTP connection to the video preprocessing server, and send video data state information, such as a collection location and a collection duration.
In one embodiment of the invention, the tachograph may send video data status information to the video pre-processing server at regular time intervals (e.g., 5 minutes).
Step S709, the video preprocessing server captures corresponding video data from the event data recorder according to the received video data state information. Specifically, after the video preprocessing server receives the video data state information, it can determine whether to initiate video capture. If the video needs to be acquired, the video preprocessing server can send a video acquisition command, and the automobile data recorder initiates video uploading after receiving the video acquisition command; if the video does not need to be collected, the video preprocessing server can keep a silent state after receiving the video data state information.
Example 2 where video preprocessing Server actively grabs video data from Driving record：
Referring to fig. 8, a method for uploading video data according to an embodiment of the present invention includes the following steps:
in step S801, the automobile data recorder sends an HTTP request message (the HTTP request message includes state information of the video data) to the MEC server, where the HTTP request message may be a TCP message with a destination port of 80.
Step S802, after receiving the HTTP request message sent by the automobile data recorder, the MEC server detects the HTTP request message from the automobile data recorder, and if the MEC server detects that the HTTP request message includes predetermined Host information (e.g., < bucktname > - < APPID >. cos. < Region >. myqcloud. com) and PATH information (/ < ObjectName >), replaces the destination IP address of the HTTP request message with the address of the video preprocessing server.
In one embodiment of the present invention, the MEC server may process the HTTP request packet forwarded to the video pre-processing server in the form of a reverse transparent proxy in step S802. Specifically, the MEC server replaces the destination IP address of the HTTP request message with the IP address of the video preprocessing server, and records the direct correspondence between the source IP address and the source port number of the corresponding HTTP request message and the original destination IP address, namely < (source IP, source port), destinationIP >.
Step S803, the MEC server forwards the processed HTTP request packet to the video pre-processing server.
In step S804, the video preprocessing server sends HTTP response information to the MEC server, where the HTTP response information may include capture information of the video data (e.g., host information for receiving the video data and informing the car recorder to upload the video data to the car recorder), and the like.
Step S805, after receiving the HTTP response information sent by the video preprocessing server, the MEC server replaces the source IP address of the HTTP response information with the original destination IP address of the HTTP request message according to the correspondence recorded in advance.
Step S806, the MEC server forwards the processed HTTP response information to the automobile data recorder, so that the automobile data recorder uploads the video data accordingly.
According to the technical scheme of the embodiment of the invention, more time is reserved for video identification processing by utilizing the ultra-short transmission time delay between the video preprocessing server and the automobile data recorder, so that the accuracy of subsequent video data identification processing can be improved. In addition, when the number of the automobile data recorders is changed, the technical scheme of the embodiment of the invention can utilize the computing resources in the edge computing facility to perform elastic processing. For example, if the number of the automobile data recorders is increased, more computing resources are provided for the video preprocessing server to enhance the processing capacity of the video preprocessing server. Otherwise, the computing resources are released, and the system operation cost is saved.
In addition, the technical scheme of the embodiment of the invention can effectively reduce the video data volume transmitted to the background server and save network resources by introducing the video preprocessing server. Meanwhile, the video preprocessing server bears most of the video analysis and identification work, so that the configuration requirement on the automobile data recorder can be reduced, and the deployment cost is saved.
In addition, the technical scheme of the embodiment of the invention enables the automobile data recorder to automatically upload videos without manual operation, thereby realizing the automation of road data acquisition and improving the timeliness of data updating. And the processing capacity of the MEC server is enhanced, so that the automobile data recorder can be automatically accessed to the video preprocessing server close to the position of the automobile data recorder, and the heavy work such as scanning a large number of IP address sections which can occur when the server actively grabs the video is avoided.
