Fig. 1 is a schematic diagram of an information transmission system to which the information transmission method according to the embodiment of the present invention is applied, and as shown in fig. 1, the information transmission system includes a server 10, a first terminal device 11, and a second terminal device 12. The server 10 is configured to receive user information sent by the first terminal device 11, and update a corresponding first version sequence number according to the user information. And then the user feedback information comprising the first version serial number is returned to the first terminal equipment 11, and the broadcast information comprising the first version serial number is sent to the corresponding at least one second terminal equipment 12.
The embodiment of the invention can be applied to any information transmission system in which the terminal equipment and the server transmit information. Such as social software, live software, and application scenarios such as online educational websites. In the embodiment of the present invention, the first terminal device 11 and the second terminal device 12 may be general-purpose data processing terminals with communication functions, such as smart phones or tablet computers, capable of running computer programs. The server 10 may be a single server or may be a cluster of servers configured in a distributed manner.
The application scenario of the information transmission method for the online education platform is described as an example. The server 10 is a platform server of an online education platform, the first terminal device 11 may be a teacher terminal used by a teacher user or a student terminal used by a student user, and the second terminal device 11 is a teacher terminal or a student terminal logged in the same virtual classroom with the first terminal device 11. When the student user and the teacher user enter the virtual classroom, and when the students perform actions such as displaying courseware, controlling PPT page turning, and submitting homework, the student user and the teacher user need to send corresponding user information to the server 10. The server 10 maintains a first version number corresponding to each virtual classroom, and when user information is received, updates the corresponding first version number according to the virtual classroom corresponding to the user information. Meanwhile, after updating the first version number, the server 10 synchronizes the updated first version number to the first terminal device 11 that sends the user information and the second terminal device 12 that logs in the same virtual classroom with the first terminal device 11 by feeding back the user feedback message and pushing the broadcast information.
For example, when the teacher terminal initiates the PPT page turning action instruction, the first terminal device 11 in the information transmission system is a teacher terminal, and the second terminal device 12 is a student terminal. The teacher terminal sends a page turning action instruction to the server 10, and the server 10 updates the first version serial number of the virtual classroom where the teacher terminal is located after receiving the page turning action instruction. And returning a page turning action instruction feedback message comprising the first version sequence number to the teacher terminal so as to inform the teacher terminal of receiving the page turning action instruction, and synchronizing the first version number at the teacher terminal. Meanwhile, the server 10 also transmits broadcast information including the first version number and page turning information to the student terminals. And displaying the turned PPT at the student terminal and synchronizing the corresponding first version serial number at the student terminal.
Fig. 2 is a flowchart of an information transmission method at a server according to an embodiment of the present invention. As shown in fig. 2, the information transmission method includes the steps of:
s100, determining a first version serial number corresponding to the virtual space identifier.
Specifically, the server may create a corresponding virtual space based on a virtual space creation request sent by a preset virtual space creation rule terminal device, where the virtual space is a specific space that may log in a plurality of terminal devices, for example, may be an online classroom of an online education platform, a live room of a live platform, a group chat of a social platform, a group, a channel of a music broadcasting platform, and so on. And each virtual space generates a corresponding first version sequence number when the creation is successful, and the corresponding first version sequence number is used for representing the state of the corresponding virtual space. And when events such as an information transmission process, a data processing process and the like occur in the corresponding virtual space, determining the final state of the corresponding virtual space by updating the first version sequence number. Meanwhile, the server can synchronize the final state of the virtual space through the terminal devices which log in the virtual space in a mode of sending the updated first version serial number. In the embodiment of the invention, the correspondence between the virtual space and the first version number may be stored by maintaining a key value pair table in the server, that is, storing a virtual space identifier and the corresponding first version number in a key value pair manner, where the virtual space identifier is used to characterize the corresponding virtual space. Optionally, when each virtual space is created by the server, the initial value of the corresponding generated first version sequence number is 0. And when the server receives an information transmission request or a data processing request corresponding to the virtual space, adding one on the basis of the current first version sequence number.
The embodiment of the invention is applied to an online education platform for explanation. The server of the online education platform can create a corresponding online virtual classroom according to a classroom creation request sent by a teacher terminal or preset classroom configuration information, and creates a corresponding first version serial number while creating the virtual classroom. The online virtual classroom can be used for a plurality of teacher terminals and student terminals to log in for online teaching.
Step 200, in response to receiving the user information including the virtual space identifier, updating the corresponding first version number.
Specifically, in the process of requesting to log in the virtual space and performing information transmission and data processing in the logged in virtual space, the terminal device sends corresponding user information to the server, where the user information is used to characterize a task that the terminal device requests the server to process. When the terminal equipment requests to log in the virtual space, the user information sent to the server is access information comprising the virtual space identifier. The access information is information of the terminal device accessing the virtual space and exiting the virtual space, and may be, for example, a request for logging in the virtual space, a notification for exiting the virtual space, or the like. And when the terminal equipment performs information transmission and data processing in the logged-in virtual space, sending an operation instruction comprising the virtual space identifier to a server. The operation instruction is an instruction for triggering an event in the virtual space, such as a PPT page turning instruction, a job submitting instruction, a forbidden language instruction of a live broadcast platform and the like in the online education process. And when receiving the user information, the server performs corresponding processing based on the user information. And simultaneously, the server determines a corresponding first version sequence number according to the virtual space identifier in the user information, and updates the first version sequence number according to a preset version sequence number updating rule. In the embodiment of the present invention, the version sequence number updating rule may be to add one to the current first version sequence number when receiving the user information each time, so as to obtain an updated first version sequence number.
The embodiment of the invention is applied to an online education platform for explanation. And for the online virtual classrooms which are not logged in the user terminal, the corresponding first version serial number is 0. When the teacher terminal sends access information comprising the virtual space identifier to the server, the server adds the teacher terminal into an online virtual classroom corresponding to the virtual space identifier. And meanwhile, the server also determines that the corresponding first version serial number is 0 according to the virtual space identifier, and updates the first version serial number to 1.
And step S300, returning user feedback information comprising the first version sequence number to the first terminal equipment for sending the user information.
Specifically, each virtual space in the server may log in at least one terminal device. Among the terminal devices registered in the virtual space, the terminal device that transmits the user information to the server is the first terminal device, and the terminal device that does not transmit the user information to the server is the second terminal device. The first terminal equipment and the second terminal equipment which are logged in each virtual space need to be dynamically determined, when the server receives user information corresponding to the virtual space, the terminal equipment which sends the user information is determined to be the first terminal equipment corresponding to the virtual space, and the terminal equipment which is logged in the virtual space is the second terminal equipment except the first terminal equipment.
In the embodiment of the invention, after receiving the user information and determining the first terminal equipment for sending the user information, the server returns user feedback information based on the user information. The user feedback information is used for reminding the first terminal equipment that the user information is successfully sent. Meanwhile, the user feedback information further comprises an updated first version sequence number, and the updated first version sequence number is used for synchronizing the current state of the corresponding virtual space with the first terminal equipment.
The embodiment of the invention is applied to an online education platform for explanation. And for the online virtual classrooms which are not logged in the user terminal, the corresponding first version serial number is 0. When the teacher terminal sends access information comprising the virtual space identifier to the server, the server adds the teacher terminal into an online virtual classroom corresponding to the virtual space identifier and updates the first version number to 1. After updating the first version number, the server transmits access success information including the first version number having a value of 1 to the teacher terminal. And the teacher terminal judges that the teacher terminal is added into the corresponding online virtual classroom after receiving the access success information, and simultaneously stores the first version serial number 1 as a second version serial number to the local.
And step 400, sending the broadcast information comprising the first version sequence number to the second terminal equipment corresponding to the virtual space identifier.
Specifically, step S400 in the embodiment of the present invention may be performed simultaneously with step S300, that is, after updating the first version sequence number, the server may simultaneously send user feedback information and broadcast information including the first version sequence number to the first terminal device and the second terminal device, respectively. The broadcast information is used for notifying details of the change of the current state of the corresponding virtual space of the second terminal equipment, and the first version sequence number is used for synchronizing the current state of the corresponding virtual space with the second terminal equipment.
The embodiment of the invention is applied to an online education platform for explanation. For the online virtual classroom in which the teacher terminal is logged in, the corresponding first version number is 1. When a student terminal sends access information comprising a virtual space identifier to a server, the server adds the student terminal into an online virtual classroom corresponding to the virtual space identifier and updates the first version serial number to 2. After updating the first version number, the server transmits access success information including the first version number of 2 to the student terminals, and simultaneously transmits a student terminal joining broadcast including the first version number of 2 to the teacher terminal. And the student terminal judges that the student terminal is added into the corresponding online virtual classroom after receiving the access success information, and simultaneously stores the first version serial number 2 as a second version serial number to the local. And after receiving the student terminal joining broadcast, the teacher terminal displays an online virtual classroom interface after the student terminal joining. And updating the local second version sequence number value to 2 according to the received first version sequence number.
Fig. 3 is a data flow chart of an information transmission method at a server according to an embodiment of the present invention. As shown in fig. 3, the information transmission process is as follows:
s30: the user information is sent by the first terminal device 30 to the server 31.
S31: the server 31 updates the first version number based on the user information. Wherein, after receiving the user information, the server 31 determines a virtual space corresponding to a virtual space identifier included in the user information. Further, the corresponding first version number and the second terminal device 32 of the virtual space login are determined according to the corresponding virtual space. And updating the first version sequence number.
S32: the user feedback information including the updated first version number is sent to the first terminal device 30.
S33: the broadcast information including the updated first version number is transmitted to the second terminal device 32.
In the process of information transmission, information may be missed due to network failure or the like. For example, in the embodiment of the present invention, the server may miss broadcast information or feedback information from the user. Therefore, in order to avoid the situation that the information leaks, the information transmission method according to the embodiment of the present invention may further include the following steps:
step S500, receiving heartbeat information including the virtual space identifier and the second version serial number.
Specifically, the terminal device registered in the virtual space may periodically send heartbeat information to the server. The heartbeat information is a small data packet sent to the server by the terminal equipment at intervals, and is used for reporting the activity to the server, and judging whether the communication link is disconnected or not through the reply condition of the server. In the information transmission process of the embodiment of the invention, in order to ensure that the virtual space state determined by the terminal equipment is the same as the virtual space state determined by the server, the terminal equipment logged in the virtual space sends the local second version serial number and the logged-in virtual space identifier to the server together with the heartbeat information.
Further, in order to improve efficiency of the heartbeat information transmission process, the embodiment of the invention can further send the heartbeat information including the virtual space identifier and the second version sequence number to the server under the preset condition. For example, when the terminal device does not receive new broadcast information within a preset time period after receiving the broadcast information last time, the new broadcast information can be sent to the server together with the second version serial number by carrying the virtual space identifier by heartbeat information sent to the server at regular time.
And step S600, responding to the second version sequence number smaller than the first version sequence number corresponding to the virtual space identifier, and determining at least one missed broadcasting message according to the second version sequence number and the first version sequence number.
Specifically, after the server receives the heartbeat information, the heartbeat information is analyzed to obtain a second version serial number and a virtual space identifier corresponding to the terminal equipment. And determining a corresponding first version signal according to the virtual space identifier, and comparing the first version signal with the second version sequence number to judge whether missed broadcasting information exists. And when the first version sequence number is the same as the second version sequence number, the server successfully updates and judges that the missed broadcasting information does not exist according to the second version sequence number. When the first version sequence number is larger than the second version sequence number, the server judges that missed broadcasting information exists according to unsuccessful updating of the second version sequence number, so that the first version sequence number included in the server is not timely synchronized to the terminal equipment.
After creating the virtual space, the server receives the user information sent by the terminal equipment logged in by the virtual space, and stores the user information according to the time sequence of receiving the user information. Therefore, when the server determines that the first version sequence number is greater than the second version sequence number, the server can determine the quantity of missed broadcast information according to the difference value between the first version sequence number and the second version sequence number. And acquiring the missed transmission quantity of the user information from the stored user information according to the storage time from late to early, and generating corresponding broadcast information based on each piece of the user information.
Step S700, returning the heartbeat feedback information including the first version number and each missed broadcast information.
Specifically, after receiving the heartbeat information sent by the terminal device, the server feeds back heartbeat feedback information to the terminal device each time, so as to inform the terminal device that the heartbeat information is received. Meanwhile, when the server compares the first version sequence number with the second version sequence number and finds that missed broadcast information exists, the missed broadcast information and the first version sequence number are transmitted to the terminal equipment together with heartbeat feedback information. And the terminal equipment updates a local second version sequence number according to the first version sequence number and stores each piece of broadcasting information.
Fig. 4 is a data flow chart of an information synchronization process at a server side according to an embodiment of the present invention. As shown in fig. 4, the information synchronization process includes:
s40: and sending heartbeat information to the server 40 through the terminal equipment 41, wherein the heartbeat information comprises the virtual space identifier logged in by the terminal equipment 41 and the corresponding second version serial number.
S41: when determining that the second version number is smaller than the first version number corresponding to the virtual space identifier, the server 40 determines at least one missed broadcast message according to the second version number and the first version number.
S42: after determining the missed broadcast information, the server 40 transmits the missed broadcast information and the first version sequence number to the terminal device 41 together with the heartbeat feedback information.
The information transmission method of the embodiment of the invention is based on the virtual space for communication, and a first version sequence number corresponding to the virtual space is introduced in the communication process. The information transmission process is monitored by updating the first version sequence number when the information is received each time, and the situation that the information is missed or lost is avoided by synchronizing the first version sequence number with the terminal equipment logged in the virtual space after the information is transmitted each time, so that the reliability of the information transmission process is ensured.
Fig. 5 is a flowchart of an information transmission method at a terminal device according to an embodiment of the present invention. As shown in fig. 5, the information transmission method of the terminal device side includes the following steps:
step S800, user information is sent.
Specifically, in the process of requesting to log in the virtual space and performing information transmission and data processing in the logged in virtual space, the terminal device sends corresponding user information to the server, where the user information is used to characterize a task that the terminal device requests the server to process. For example, when the terminal device requests to log in the virtual space, the user information sent to the server is access information including the virtual space identifier; and when the terminal equipment performs information transmission and data processing in the logged-in virtual space, sending an operation instruction comprising the virtual space identifier to a server.
Step S900, the second version serial number is determined in response to receiving user feedback information returned by the server based on the user information.
Specifically, after receiving user information sent by the terminal equipment, the server returns user feedback information based on the user information. The user feedback information is used for reminding the terminal equipment that the user information is successfully sent. Meanwhile, the user feedback information also comprises an updated version sequence number which is used for synchronizing the current state of the corresponding virtual space with the terminal equipment.
And after receiving the user feedback information, the terminal equipment determines a local second version sequence number. The second version serial number corresponds to a virtual space in which the terminal equipment logs in. Therefore, when the user information is a request to log in the virtual space, the second version number of the current local is null. And when the user information is other information such as access information, determining that the current second version sequence number is the version sequence number updated last time.
Further, when the terminal device does not receive the user feedback information within a preset time period after sending the user information, the user information is considered to be failed to send, and the user information is sent to the server again.
And step S1000, updating the second version sequence number according to the first version sequence number in the user feedback information.
Specifically, the terminal device updates the local second version serial number according to the first version serial number sent by the server so as to synchronize the current state of the virtual classroom. In the embodiment of the invention, when the user information sent by the terminal equipment is a request for logging in the virtual space, the current local second version sequence number is null, and the received first version sequence number is directly determined to be the second version sequence number. And when the user information is other information such as access information, the second version sequence number exists in the terminal equipment. The terminal equipment presets a preset value, and further updates the second version sequence number according to the relation between the difference value of the first version sequence number and the local second version sequence number in the user feedback information and the preset value.
In an optional implementation manner of the embodiment of the present invention, a difference value between the first version serial number and the second version serial number is a preset value, and the terminal device directly updates the second version serial number to the first version serial number. The embodiment of the invention is applied to an online education platform, and the server adds one first version serial number to the first version serial number after receiving the user information each time. For the online virtual classroom in which the teacher terminal is logged in, the corresponding first version number in the server is 1, and the second version number stored in the teacher terminal is also 1. Meanwhile, the preset value is 1. When the teacher terminal sends a PPT page turning request comprising a virtual space identifier to a server, the server updates the online virtual classroom corresponding to the virtual space identifier in the PPT page turning request to 2. After updating the first version serial number, the server sends PPT page turning request feedback information comprising the first version serial number with the value of 2 to the teacher terminal. After receiving the feedback information, the teacher terminal calculates the difference value between the first version serial number 2 and the local second version serial number 1 to be a preset value 1, so that the second version serial number is directly updated to be 2.
In another optional implementation manner of the embodiment of the present invention, a difference between the first version sequence number and the second version sequence number is greater than a preset value. When the difference is greater than a preset value, the terminal device judges that the server has missed broadcast information, so that the broadcast information needs to be further synchronized to update the second version serial number. The method for updating the second version sequence number comprises the following steps:
step 1100, sending heartbeat information including the second version sequence number in response to the difference between the first version sequence number and the second version sequence number being greater than a preset value.
Specifically, when the terminal device determines that the difference value between the first version sequence number and the second version sequence number is greater than a preset value, it is determined that the server has missed broadcast information, and heartbeat information including the second version sequence number is sent to the server. To synchronize information in the process of reporting to the server. The embodiment of the invention is applied to an online education platform, and the server adds one first version serial number to the first version serial number after receiving the user information each time. For the online virtual classroom in which the teacher terminal is logged in, the corresponding first version number in the server is 2. Meanwhile, the preset value is 1. When the second version serial number stored in the teacher terminal is 1, a PPT page turning request comprising a virtual space identifier is sent to a server, and the server updates the online virtual classroom corresponding to the virtual space identifier in the PPT page turning request to 3. After updating the first version serial number, the server sends PPT page turning request feedback information comprising the first version serial number with the value of 3 to the teacher terminal. And after receiving the feedback information, the teacher terminal calculates that the difference value between the first version serial number 3 and the local second version serial number 1 is 2 and is larger than a preset value. Therefore, the teacher terminal determines that there is missed broadcast information in the server history, and transmits heartbeat information including the second version number 1 to the server.
Step 1200, receiving heartbeat feedback information returned by the server based on the heartbeat information, where the heartbeat feedback information includes a first version sequence number and at least one corresponding broadcast information.
Specifically, after receiving the heartbeat information, the server analyzes the heartbeat information to obtain a second version serial number corresponding to the terminal equipment. The server determines a virtual space in which the terminal equipment logs in, further determines a first version signal corresponding to the virtual space identifier, and compares the first version signal with a second version sequence number to determine whether missed broadcasting information exists. When the first version sequence number is larger than the second version sequence number, the server judges that missed broadcasting information exists according to unsuccessful updating of the second version sequence number, so that the first version sequence number included in the server is not timely synchronized to the terminal equipment. And further determining the quantity of missed broadcasting information according to the difference value between the first version sequence number and the second version sequence number, acquiring the user information of the missed broadcasting quantity from late to early according to the storage time in the user information stored in the server, and generating corresponding broadcasting information based on each user information. And sending the heartbeat feedback information comprising the broadcasting information and the first version sequence number to the terminal equipment.
Step S1300, storing the broadcast information, and updating the second version sequence number to the first version sequence number.
Specifically, after receiving the heartbeat feedback information, the terminal device stores broadcast information missed by the server included in the heartbeat feedback information, and updates the local second version sequence number to the first version sequence number so as to synchronize the current state of the virtual space. Optionally, the buffer area in the terminal device for storing broadcast information is an area with a preset length. When the buffer space is occupied, the terminal device deletes the historically stored broadcast information from the buffer according to the storage time from long to short when storing the new broadcast information.
Fig. 6 is a schematic diagram of an information synchronization process at a terminal device according to an embodiment of the present invention. As shown in fig. 6, the information synchronization process is that after receiving user feedback information fed back by the server based on the user information, the terminal device calculates a difference 61 between the first version sequence number and the local second version sequence number in the user feedback information 60. An update process 62 of the second version number is further determined by comparing the difference value with a preset value. And when the difference value is equal to a preset value, directly updating the second version sequence number to be the first version sequence number 65. When the difference is greater than the threshold, it is determined that there is missed broadcast information in the server, and the heartbeat information including the second version number is sent to the server 63. The server returns heartbeat feedback information 64 including missed broadcast information and the first version sequence number to the terminal device based on the heartbeat information, and the terminal device stores each broadcast information after receiving the heartbeat feedback information. And simultaneously, updating the second version sequence number to be the first version sequence number 65.
The information transmission method of the embodiment of the invention is based on the virtual space for communication, and a first version sequence number corresponding to the virtual space is introduced in the communication process. The information transmission process is monitored according to the difference between the first version sequence number and the local second version sequence number of the server when the user feedback information is received each time, and the information is prevented from being missed or lost in a mode of synchronizing the heartbeat information under the condition of missed information transmission, so that the reliability of the information transmission process is ensured.
