Detailed ways

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The Internet of Vision is an important milestone in the development of the network. It is a real-time network that can realize real-time transmission of high-definition video, and push many Internet applications to high-definition video, high-definition face-to-face.

The Internet of View adopts real-time high-definition video exchange technology, which can provide required services on one network platform, such as high-definition video conferencing, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcast TV, time-lapse TV, online teaching, live broadcast , VOD on demand, TV mail, personalized recording (PVR), intranet (self-managed) channel, intelligent video broadcast control, information release and other dozens of video, voice, picture, text, communication, data and other services are all integrated in one System platform, realize high-definition quality video playback through TV or computer.

In order to enable those skilled in the art to better understand the embodiments of the present invention, the Internet of Things is introduced as follows:

Some of the technologies applied in the Internet of Things are as follows:

Network Technology

The network technology innovation of the Internet of View has improved the traditional Ethernet (Ethernet) to face the potentially huge first video traffic on the network. Different from pure network packet switching (Packet Switching) or network circuit switching (Circuit Switching), video networking technology uses Packet Switching to meet Streaming requirements. The Internet of Vision technology has the flexibility, simplicity and low price of packet switching, and at the same time has the quality and security guarantee of circuit switching, realizing the seamless connection of switched virtual circuits and data formats throughout the network.

Switching Technology

Video networking adopts the two advantages of Ethernet asynchronous and packet switching, eliminates the defects of Ethernet under the premise of full compatibility, has end-to-end seamless connection of the whole network, directly connects to user terminals, and directly carries IP data packets. User data does not require any format conversion within the entire network. Video networking is a more advanced form of Ethernet. It is a real-time switching platform, which can realize the real-time transmission of large-scale high-definition video in the whole network that cannot be realized by the Internet at present, and push many network video applications to high-definition and unification.

Server Technology

The server technology on the Internet of View and unified video platform is different from the server in the traditional sense. Its streaming media transmission is based on connection-oriented, and its data processing capability has nothing to do with traffic and communication time. A single network layer can contain information command and data transmission. For voice and video services, the complexity of video streaming and unified video platform streaming media processing is much simpler than data processing, and the efficiency is greatly improved by more than 100 times compared with traditional servers.

Storage Technology

The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system in order to adapt to the super-large capacity and super-large-flow media content, and maps the program information in the server command to the specific hard disk space, and the media content no longer passes through the server. It is delivered directly to the user terminal in an instant, and the user generally waits for less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical movement of the hard disk head seeking. The resource consumption is only 20% of that of IP Internet at the same level, but the concurrent traffic generated is 3 times larger than that of the traditional hard disk array, and the overall efficiency is increased by more than 10 times.

Network Security Technology

The structural design of the Internet of View completely eradicates the network security problems that plague the Internet through the individual licensing system for each service, complete isolation of equipment and user data, and generally does not require anti-virus programs and firewalls, preventing hackers and virus attacks , to provide users with a structured worry-free security network.

Service Innovation Technology

The unified video platform integrates business and transmission together, whether it is a single user, a private network user or the sum of a network, it is just an automatic connection. User terminals, set-top boxes or PCs are directly connected to the unified video platform to obtain rich and colorful multimedia video services in various forms. The unified video platform adopts the "recipe-style" table matching mode to replace the traditional complex application programming. It can realize complex applications with very little code and realize "unlimited" new business innovations.

The networking of the Internet of View is as follows:

Vision networking is a network structure with centralized control. The network can be a tree network, star network, ring network, etc., but on this basis, a centralized control node is required in the network to control the entire network.

As shown in Figure 1, the Internet of Things is divided into two parts: the access network and the metropolitan area network.

The equipment in the access network can be mainly divided into three categories: node servers, access switches, and terminals (including various set-top boxes, encoding boards, memory, etc.). The node server is connected with the access switch, and the access switch can be connected with multiple terminals and can be connected with Ethernet.

Wherein, the node server is a node with centralized control function in the access network, which can control the access switches and terminals. The node server can be directly connected to the access switch, and can also be directly connected to the terminal.

Similarly, the devices in the MAN part can also be divided into three categories: MAN servers, node switches, and node servers. The metro server is connected to the node switch, and the node switch can be connected to multiple node servers.

Wherein, the node server is the node server of the access network part, that is, the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node with a centralized control function in the metropolitan area network, which can control node switches and node servers. The metro server can be directly connected to the node switch, or directly connected to the node server.

It can be seen that the entire Vision Network is a layered centralized control network structure, while the network controlled by the node server and the metro server can be in various structures such as tree, star, and ring.

Vividly speaking, the access network part can form a unified video platform (the part in the dotted circle), and multiple unified video platforms can form a video network; each unified video platform can be interconnected through the metropolitan area and the wide area video network.

Classification of Internet of Things devices

1.1 The equipment in the video network of the embodiment of the present invention can be mainly divided into three categories: servers, switches (including Ethernet protocol conversion gateways), terminals (including various set-top boxes, encoding boards, memory, etc.). As a whole, the Internet of Things can be divided into a metropolitan area network (or a national network, a global network, etc.) and an access network.

1.2 The equipment in the access network can be mainly divided into three categories: node server, access switch (including Ethernet protocol conversion gateway), terminal (including various set-top boxes, encoding boards, storage, etc.).

The specific hardware structure of each access network device is:

Wherein, the packet (upstream data) that the downstream network interface module 301 comes in enters the packet detection module 305; Whether the destination address (DA), source address (SA), data packet type and packet length of the packet detection module 305 detection packet meet the requirements, if Meet, then distribute corresponding flow identifier (stream-id), and enter switching engine module 303, otherwise discard; The packet (downstream data) that upstream network interface module 302 comes in enters switching engine module 303; The data packet that CPU module 304 comes in Enter switching engine module 303; Switching engine module 303 carries out the operation of looking into address table 306 to the bag that comes in, thereby obtains the guiding information of packet; If the bag that enters switching engine module 303 is that downlink network interface goes to uplink network interface, then combines Flow identifier (stream-id) stores this packet into the queue of corresponding packet cache 307; If the queue of this packet cache 307 is close to full, then discards; If the packet that enters switching engine module 303 is not downlink network interface, goes up If the data packet is sent to the network interface, the data packet is stored in the queue of the corresponding packet buffer 307 according to the direction information of the packet; if the queue of the packet buffer 307 is nearly full, it is discarded.

The switching engine module 303 polls all packet buffer queues, which can include two situations:

If the queue goes from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the port sending buffer is not full; 2) the queue packet counter is greater than zero; 3) the token generated by the code rate control module is obtained ;

If the queue does not go from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the sending buffer of the port is not full; 2) the packet counter of the queue is greater than zero.

The code rate control module 308 is configured by the CPU module 304 to generate tokens for all packet buffer queues going from the downlink network interface to the uplink network interface within a programmable interval to control the uplink forwarding code rate.

The CPU module 304 is mainly responsible for protocol processing with the node server, configuration of the address table 306 , and configuration of the code rate control module 308 .

Among them, the node switch mainly includes a network interface module, a switching engine module and a CPU module; the metro server mainly includes a network interface module, a switching engine module and a CPU module.

2. Definition of Internet of Things data package

2.1 Definition of access network data packet

The data packet of the access network mainly includes the following parts: destination address (DA), source address (SA), reserved bytes, payload (PDU), and CRC.

As shown in the table below, the data packets of the access network mainly include the following parts:

DA SA Reserved Payload CRC

in:

The destination address (DA) consists of 8 bytes (byte), the first byte indicates the type of data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are up to 256 possibilities, The second byte to the sixth byte is the address of the metropolitan area network, and the seventh and eighth bytes are the address of the access network;

The source address (SA) is also composed of 8 bytes (byte), and the definition is the same as that of the destination address (DA);

Reserved bytes consist of 2 bytes;

The payload part has different lengths according to different datagram types. If it is a variety of protocol packets, it is 64 bytes. If it is a single multicast data packet, it is 32+1024=1056 bytes. Of course, it is not limited to Above 2 types;

CRC consists of 4 bytes, and its calculation method follows the standard Ethernet CRC algorithm.

2.2 MAN packet definition

The topology of the metropolitan area network is a graph. There may be two or even more than two types of connections between two devices, that is, there may be more than 2 connections between node switches and node servers, node switches and node switches, and node switches and node servers. kind of connection. However, the MAN address of the MAN device is unique. In order to accurately describe the connection relationship between MAN devices, a parameter: label is introduced in the embodiment of the present invention to uniquely describe a MAN device.

The definition of labels in this manual is similar to the definition of labels in MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switching). Assuming that there are two connections between device A and device B, then the data packets from device A to device B have 2 labels, the packet from device B to device A also has 2 labels. The label is divided into an incoming label and an outgoing label. Assuming that the label (incoming label) of the data packet entering device A is 0x0000, the label (outgoing label) of the data packet when it leaves device A may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, which means that the address allocation and label allocation of the metropolitan area network are all dominated by the metropolitan area server, and the node switches and node servers are all passively executed. Different from MPLS label allocation, MPLS label allocation is the result of mutual negotiation between switches and servers.

As shown in the table below, the data packet of the MAN mainly includes the following parts:

DA SA Reserved Label Payload CRC

That is, destination address (DA), source address (SA), reserved byte (Reserved), label, payload (PDU), and CRC. Among them, the format of the label can refer to the following definition: the label is 32bit, of which the high 16bit is reserved, and only the low 16bit is used, and its position is between the reserved byte of the data packet and the payload.

First, the stored procedure of meeting files is introduced.

In the embodiment of the present invention, the conference file and the corresponding UCL (Uniform Content Locator, unified content location) object are stored in the storage service system during the video conference. The embodiment of the present invention is mainly described by taking a video conferencing networked as an example.

Referring to FIG. 5 , it shows a schematic diagram of device interaction according to an embodiment of the present invention. The device shown in FIG. 5 can be applied to video conferencing on the Internet of Things. It can be seen from Fig. 5 that the video networking server can communicate with the video networking terminal 1, the video networking terminal 2 (can also include other multiple video networking terminals), the conference management server, the storage service system (specifically, it can be the storage gateway in the storage service system) ) for two-way interaction. The conference control terminal can perform two-way interaction with the conference management server. The conference management server can perform two-way interaction with the storage service system (specifically, it can be a storage gateway in the storage service system). The storage service system may include modules such as a content management platform, a video server, a storage gateway, a Web player, and a UCL object.

The conference control terminal can be used to initiate an instruction to control the conference, for example, a group meeting instruction, a speaker switching instruction, and the like. The conference management server can receive the instruction sent by the conference control terminal, parse the instruction and forward it to the video network server, and then the video network server forwards it to the corresponding terminal. The Internet-connected terminal can be a variety of set-top boxes and the like. The storage service system is responsible for the storage of audio and video data of the Internet of Vision, and the transmission of audio and video data of the Internet to the Internet of Vision.

In the Internet of Vision, the Internet of Vision services are managed uniformly by the Internet of Vision server (which may be the node server in FIG. 1 ). Devices that interact with the Internet of Vision server must be pre-registered with the Internet of Vision server, and only after registration can they access the Internet of Vision for normal business. After the registration is successful, the video network server can assign the video network number, the video network MAC (Media Access Control Address, media access control) address and other information to the corresponding device.

Referring to FIG. 6 , it shows a flowchart of steps of a file storage method according to an embodiment of the present invention.

The file storage method of the embodiment of the present invention may include the following steps:

In step 601, the storage service system receives a recording start instruction sent by the conference control terminal, and creates a UCL object.

In the video conference of the Internet of View, when setting up a video conference, relevant conference settings can be made on the conference control terminal, such as selecting the participating terminal, setting the role of the participating terminal, etc., and triggering the group meeting command after the setting is completed . The conference control terminal sends the group meeting instruction to the conference management server, and the conference management server forwards the instruction to the video networking server, and then the video networking server notifies the corresponding video networking terminal to join the video conference. The Internet-connected terminal that joins the video conference is the participating terminal.

During the video conference, speech data such as audio and video in the video conference can be recorded, and then conference files corresponding to the video conference can be obtained. Executing corresponding operations on the conference control terminal can trigger the conference control terminal to generate a recording start instruction. For example, the conference control terminal displays the logos of each participating terminal, and can provide a "Start Recording" button. The user can select the target terminal logo and click the "Start Recording" button to trigger the start recording command. Information such as the target terminal identifier may be carried in the start recording instruction.

The conference control terminal and the conference management server can interact based on the Internet protocol, and the conference management server and the storage service system can also interact based on the Internet protocol. Therefore, the conference control terminal sends the recording start instruction to the conference management server based on the Internet protocol, and the conference management server sends the recording start instruction to the storage service system based on the Internet protocol. After receiving the recording start instruction, the storage service system creates a UCL object corresponding to the conference file to be generated after this recording.

In implementation, the conference management server may specifically send the recording start instruction to the storage gateway in the storage service system, and after receiving the recording start instruction, the storage gateway creates a UCL object corresponding to the conference file to be generated after this recording.

Step 602, the storage service system retrieves the speech data of the target participant terminal according to the recording start instruction, and starts recording the speech data.

In the video conference of the Internet of View, the process for the storage service system to retrieve the speech data of the target participant terminal according to the start recording instruction may include steps A1-A3. The following steps A1-A3 can be specifically executed by the storage gateway in the storage service system.

In step A1, the storage service system extracts the target terminal identifier from the recording start instruction, and sends the streaming request to the target participant terminal corresponding to the target terminal identifier based on the Internet of Vision protocol.

After the storage service system (specifically, the storage gateway) receives the recording start instruction, it parses the recording start instruction, extracts the target terminal ID from it, and generates a streaming request for the participating terminal corresponding to the target terminal ID. Information such as the target terminal identifier may be carried in the stream regulation request. The storage service system sends the flow adjustment request to the Internet of Vision server based on the Internet of Vision protocol, and then the Internet of Vision server processes the flow adjustment request and forwards it to the target participant terminal corresponding to the target terminal identifier.

In implementation, the storage service system may encapsulate the streaming request into a first Internet of Things protocol request packet based on the first Internet of Things protocol, and send the first Internet of Things protocol request packet to the Internet of Things server. After receiving the first Internet of Vision protocol request packet, the Internet of Vision server repackages the streaming request into a second Internet of Vision protocol request packet based on the first Internet of Vision protocol, and sends the second Internet of Vision protocol request packet to the target terminal identification corresponding target participant terminals. Wherein, the first video networking protocol may be a protocol for transmitting service operation commands from the terminal to the server, and the second video networking protocol may be a protocol for transmitting service operation commands from the server to the terminal.

Step A2, the storage service system receives the Internet of Vision protocol data packet returned by the target participant terminal based on the Internet of Vision protocol; the speech data is encapsulated in the Internet of Vision protocol data packet.

After receiving the streaming request, the target participant terminal obtains the collected speech data, which may include video and audio. The target participant terminal encapsulates the speech data into a video network protocol packet based on the third video network protocol, and adds a video network MAC address for the video network protocol packet, and the video network MAC address can include the video network MAC address of the target participant terminal ( source address) and the Internet-based MAC address (destination address) of the storage gateway in the storage service system. The target participating terminal sends the Internet of Vision protocol data packet to the Internet of Vision server, and then the Internet of Vision server forwards the Internet of Vision protocol data packet to the storage service system (specifically, the storage gateway). The third internet of vision protocol may be a protocol used for data transmission in the internet of vision.

In step A3, the storage service system converts the Internet Protocol data packet into an Internet Protocol data packet; the speech data is encapsulated in the Internet Protocol data packet.

Speech data can be recorded by the recording server in the storage service system. The storage service system (specifically, the storage gateway) converts the Internet Protocol data packet into an Internet Protocol data packet.

The step of converting the Internet of Vision protocol data packet into the Internet Protocol data packet may include: the storage service system (specifically, a storage gateway) parses the Internet of Vision protocol data packet, and deletes the Internet of Vision MAC address added in the Internet of Vision protocol data packet , extracting the speech data; the storage service system adds an Internet protocol header to the speech data, and encapsulates the speech data into the Internet protocol data packet based on the Internet protocol. The Internet Protocol packet header may include information such as an IP (Internet Protocol, a protocol for interconnecting networks) address (source address) of a storage gateway, an IP address (destination address) of a recording server, and the like.

The storage gateway can send the recording start instruction and the Internet protocol data packet to the recording server, and the recording server records the speech data.

Step 603, the storage service system receives the instruction to stop recording sent by the conference control terminal, and generates a conference file according to the speech data that has been recorded.

When you want to stop recording speech data, you can send a stop recording command. Executing corresponding operations on the conference control terminal can trigger the conference control terminal to generate a stop recording instruction. For example, a "stop recording" button may be provided on the conference control terminal, and the user may trigger an instruction to stop recording after clicking the "stop recording" button. The above-mentioned target terminal identifier and other information may be carried in the stop recording instruction.

The conference control terminal sends the recording stop instruction to the conference management server based on the Internet protocol, and the conference management server sends the recording stop instruction to the storage service system based on the Internet protocol. After receiving the instruction to stop recording, the storage service system can generate meeting files according to the recorded speech data.

In the implementation, the conference management server can specifically send the stop recording instruction to the storage gateway of the storage service system. After receiving the stop recording instruction, the storage gateway sends the stop recording instruction to the recording server based on the Internet protocol, and the recording server receives the stop recording instruction. After the instruction, generate conference files based on the recorded speech data. The conference file may be a recorded audio and video.

It should be noted that after receiving the stop recording instruction, the storage service system may also stop calling the speech data of the target participant terminal according to the stop recording instruction. The storage service system extracts the target terminal identifier from the stop recording instruction, and sends the stop stream adjustment request to the target participant terminal corresponding to the target terminal identifier based on the Internet of Vision protocol. The specific process can refer to the above step A1 for the process of sending the stream adjustment request. related description. The target participant terminal can stop sending speech data after receiving the request to stop streaming.

Step 604, the storage service system obtains attribute information corresponding to the meeting file, and writes the attribute information into the UCL object.

In an optional implementation manner, the step of the storage service system acquiring the attribute information corresponding to the conference file may include: the storage service system receiving the conference description information sent by the conference control terminal; the storage service system storing the conference description information Determine the attribute information corresponding to the meeting file.

The conference control terminal can obtain the conference description information after sending the recording start instruction, and encapsulate the conference description information into an Internet protocol data packet based on the Internet protocol, and the conference control terminal sends the Internet protocol data packet to the conference management server. After the conference management server receives the Internet protocol data packet, it converts the Internet protocol data packet into the Internet of Vision protocol data packet, specifically including analyzing the Internet protocol data packet by the management server, extracting the conference description information from it, and converting the conference description information based on the Internet of Vision protocol. Encapsulated as Internet protocol packets. The conference management server sends the Internet of Vision protocol data packet to the Internet of Vision server, and then the Internet of Vision server sends the Internet of Vision protocol data packet to the storage service system. After the storage service system receives the Internet-of-Vision protocol data packet, it parses it, extracts the conference description information from it, and writes the conference description information into the UCL object created above.

The conference description information may include some basic information of the video conference, such as conference time, conference location, number of participants, conference theme, conference copyright, and the like.

In another optional implementation manner, the step of the storage service system acquiring the attribute information corresponding to the conference file may include: the storage service system detects whether there is any key content in the speech data during the process of recording the speech data information; if the storage service system detects that it exists, it will determine the key content information as the attribute information corresponding to the conference file.

During the process of recording speech data, the storage service system (specifically, the video recording server) can perform face recognition and speech recognition on the speech data, so as to detect whether there is key content information in the speech data. Wherein, the key content information may include some key information in speech data, such as key figures (may be leaders, etc.), Guan Jian's speech content, and the like.

For example, the storage service system can pre-store the face features of key people, the voice features of key content, and so on. The recording server performs face recognition on the video image in the speech data to obtain the face features, and matches the face features with the stored key person's face features. If the face feature matching is successful, then determine that the person in the current video image is key person. The recording server performs speech recognition on the audio data in the speech data to obtain speech features, and matches the speech features with the speech features of the stored key content. If the speech features are successfully matched, then determine that the current audio data is the speech content of Guan Jian.

If the storage service system detects that there is key content information in the utterance data, it will write the key content information into the UCL object created above.

In another optional implementation manner, the step of the storage service system obtaining the attribute information corresponding to the conference file may include: after the storage service system generates the conference file according to the speech data that has been recorded, obtains the file corresponding to the conference file Description information: the storage service system determines the file description information as attribute information corresponding to the meeting file.

After the storage service system stops recording and generates conference files based on the recorded speech data, it can also obtain the file description information corresponding to the conference files, and write the file description information into the UCL object created above.

Wherein, the file description information may include information such as file format, file resolution, file duration, file subject type, file copyright, file creation time, file author, terminal identification corresponding to the file, and terminal location.

Step 605, the storage service system stores the meeting file and the UCL object correspondingly.

The storage service system stores the conference file and the UCL object correspondingly, and each conference file has a corresponding UCL object. Of course the meeting document also has a document name. The UCL object can reflect the attribute information of the corresponding meeting document, and can describe the meeting document more comprehensively.

In the embodiment of the present invention, when the conference file is stored, it is stored in the UCL object corresponding to the conference file at the same time. The attribute information corresponding to the conference file is written in the UCL object, which can describe the conference file more accurately and comprehensively. Therefore, according to the UCL Objects can understand the relevant information of the meeting file without opening the meeting file, and the process is more convenient.

The following describes the push process of meeting documents.

Referring to FIG. 7 , it shows a flowchart of steps of a method for pushing files according to an embodiment of the present invention.

The file pushing method of the embodiment of the present invention may include the following steps:

Step 701: After the user logs in successfully, the storage service system acquires user portrait information corresponding to the user; the user portrait information includes the weight of each file topic type corresponding to the user.

The user registers an account on the storage service system. After registration, the user can log in to the storage service system. After successful login, the user can retrieve and view conference documents, etc. The storage service system can push conference files to the user after the user successfully logs in, so that the user can directly view the pushed conference files.

In the embodiment of the present invention, relevant conference files may be pushed to the user according to the user portrait information corresponding to the user. Therefore, after the user logs in successfully, the storage service system can obtain the user portrait information corresponding to the user. User profile information refers to relevant information that can describe a user. The user portrait information in the embodiment of the present invention may include the weight of each file topic type corresponding to the user, wherein the weight of the file topic type can indicate the degree of concern of the user to the file topic type, and the greater the weight of the file topic type, the greater the weight of the file topic type. It indicates that the user pays more attention to the subject type of the document, that is, the user is more interested in the subject type of the document. When it needs to be explained, the document subject type here corresponds to the document subject type included in the above-mentioned UCL object. For example, document subject types may include government, medical, educational, and so on.

In an optional implementation manner, the step of obtaining the user portrait information corresponding to the user may include: judging whether there is user portrait information corresponding to the user; if yes, obtaining the existing user portrait information corresponding to the user information; if it does not exist, create user portrait information corresponding to the user, and assign the same weight to each file subject type corresponding to the user. Wherein, the process of assigning the same weight to each file topic type corresponding to the user may include: assuming that the number of file topic types is N, the weight of each file topic type is 1/N, and N is a positive integer .

User portrait information is created after the user logs in to the storage service system for the first time, and is saved after creation. Therefore, after the user logs in successfully, the storage service system first determines whether there is user portrait information corresponding to the user. If it does not exist, it means that the user is logging in for the first time, so the user portrait information corresponding to the user is initially created, and each file subject type corresponding to the user in the newly created user portrait information has the same weight. If it exists, it means that the user is not logging in for the first time, and the user portrait information corresponding to the user has been created before, so it can be obtained directly.

Step 702, the storage service system selects the conference file corresponding to the file subject type with the highest weight.

After obtaining the user portrait information corresponding to the user, the storage service system obtains the weight of each document subject type corresponding to the user, selects the document subject type with the highest weight, and then selects the document subject type with the highest weight from the stored conference documents. Conference files corresponding to the file subject type.

The storage service system stores a plurality of conference files and a UCL object corresponding to each conference file, and the UCL object includes a file subject type corresponding to the conference file. Therefore, after the storage service system selects the file subject type with the highest weight, it traverses multiple stored UCL objects according to the file subject type, selects the UCL object including the file subject type with the highest weight from the multiple UCL objects, and the selected UCL objects The conference file corresponding to the object is the conference file corresponding to the file subject type with the highest weight.

For example, if the document subject type with the highest weight is "Government", the storage service system traverses the document subject types included in multiple UCL objects, and selects UCL objects whose document subject types include "Government", and these document subject types include " The UCL object of "Government" is the meeting document corresponding to the subject type of "Government" with the highest weight.

It should be noted that, if the weights of each document subject type included in the user profile information are the same, each document subject type is regarded as the document subject type with the highest weight. If there are multiple document subject types with the highest weight, all these document subject types are regarded as the document subject type with the highest weight.

Step 703, the storage service system pushes the selected meeting file to the user.

The storage service system selects the conference files corresponding to the file subject type with the highest weight. Users pay more attention to these conference files. Therefore, the storage service system pushes the selected conference files to users, which can arouse users' interest and push more accurately.

Considering that the weights of various file subject types in the user portrait information may change, the storage service system may also update the user portrait information.

After logging into the storage service system, the user may operate on one or more conference files, and the operations may include retrieval, playback, collection, download, and so on. The user performs the above operations on conference files, indicating that the user pays more attention to these conference files, so the weight of the file topic type corresponding to the conference file operated by the user can be increased, and the weight of the file topic type corresponding to the conference file operated by the user can be reduced accordingly Weights for other document topic types besides .

Therefore, in an optional implementation manner, the method in this embodiment of the present invention may further include: the storage service system obtains the file subject type corresponding to the conference file operated by the user after this login; the storage service system for the user For the corresponding user portrait information, increase the weight of the acquired document subject type, and decrease the weight of other document subject types except the acquired document subject type.

Optionally, the step of increasing the weight of the acquired document subject type and reducing the weight of other document subject types except the acquired document subject type may include: increasing the weight of the acquired document subject type according to a first preset ratio Weight: calculate the ratio of the first preset ratio to the number of the other file subject types, and reduce the weight of the other file subject types according to the ratio.

Wherein, for the specific numerical value of the first preset ratio, those skilled in the art may select any applicable numerical value based on actual experience, which is not limited in the embodiment of the present invention.

For example, the current user portrait information includes 8 file subject types, each of which has a weight of 1/8=12.5%, and the first preset ratio is set to 2.8%. The document subject type corresponding to the meeting documents operated by the user after this login is "government", so the weight of the document subject type "government" is increased by 2.8%, and the weight of the document subject type "government" becomes 15.3% . The first preset ratio is 2.8%, the number of other file subject types is 7, and the ratio of the first preset ratio to the number of other file subject types is 2.8%/7=0.4%, so the other 7 types Document subject types are all weighted 0.4% lower.

The user may also not pay much attention to the meeting files corresponding to one or more file subject types, so the user may not operate on the meeting files corresponding to one or more file subject types for a period of time. For these file subject types Its weight can be reduced appropriately.

Therefore, in an optional implementation manner, the method in this embodiment of the present invention may further include: if the storage service system detects that within a preset period, the user does not operate on the meeting files corresponding to one or more file subject types, Then reduce the weight of the one or more file subject types according to a second preset ratio.

Wherein, for the specific values of the preset period and the second preset ratio, those skilled in the art may select any applicable values based on actual experience, which is not limited in the embodiment of the present invention. The second preset ratio may be the same as or different from the above-mentioned first preset ratio.

For example, the preset period is set to be 1 month, and the second preset ratio is set to 1%. If the storage service system detects that the user has not operated on the conference files corresponding to the file subject type "education" within one month, the weight of the file subject type "education" will be reduced by 1%.

In the embodiment of the present invention, the conference files pushed to the user are selected according to the weight of each file topic type corresponding to the user. The weight of the file topic type can reflect the degree of attention of the user to the conference file corresponding to the file topic type. The higher the weight, the more The higher the user's attention, the more accurate the conference files pushed to the user according to the weight, which can meet the user's needs and improve the user experience.
