Description

Technical Field

[0001] The present invention relates to the field of service processing, and in particular, to a method and device for clearing services. Background Art

[0002] Services performed in a network usually rely on a core server and a service system. The core server establishes a data link to provide a channel for terminal devices to perform services; the service system can view, modify, clear, etc. the services performed by the core server. When clearing a service on the core server, usually the clearing operation is triggered by the service system. That is, the service system clears a single specified service.

[0050] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Figure 1 The method for clearing services provided by an embodiment of the present invention is shown, which is applied to the main control device in the core server. The core server further includes: a plurality of sub-control devices connected to the main control device, and each sub-control device is connected to a plurality of terminal devices; the connections between the main control device and the sub-control devices and between the sub-control devices and the terminal devices are all communication connections, for example, communication connections implemented through the Visual Networking or the Internet; the core server is connected to the service system and usually conducts a large number of services simultaneously.

[0052] The method for clearing services includes the following steps:

[0053] Step 101, receive the main control service clearing message.

[0054] It should be noted that the service clearing message can be sent through a control system connected to the main control device of the core server. The connection method between the two is a wireless communication connection, for example, through the Internet connection, but not limited to this. Specifically, the control system is connected to the core server through a TCP (Transmission Control Protocol) socket, and the user can log in to the core server through the root account registered in the core server, and then generate a main control service clearing message and send it to the core server.

[0055] Of course, the number of core servers in the network to which the core server belongs is usually multiple. Preferably, all core servers are respectively connected to the control system, so that the services carried out by all core servers can be controlled through the control system.

[0056] Step 102, according to the main control service clearing message, clear a plurality of services carried out by the main control device.

[0057] It should be noted that the main control service clearing message includes: a first instruction for indicating to clear all services, a second instruction for indicating to clear the services carried out by the target sub-control device, or a third instruction for indicating to clear the services carried out by the target terminal device: where the target sub-control device is at least one of the plurality of sub-control devices; the target terminal device is at least one of the plurality of terminal devices.

[0058] Each terminal device realizes service access through the sub-control device connected to it and the main control device connected to the sub-control device. Therefore, the relevant information of service access of all terminal devices is stored in the main control device; the relevant information of service access of the terminal devices connected to the sub-control device is stored in the sub-control device. When clearing services, while removing the data link, the relevant service information stored in the main control device and the sub-control device should also be deleted. Preferably, the service information related to the terminal device should also be deleted.

[0059] Preferably, the master service clearing message carries an operation code and a list. Different operation codes respectively correspond to a first instruction, a second instruction, and a third instruction. The master device can identify the operation code and perform different operations for different operation codes. The list can be empty or can include the identifiers of the slave devices or the identifiers of the terminal devices. After clearing the service, the master device can also return the operation result to the control system.

[0060] Step 103: According to the master service clearing message, send a slave service clearing message to at least one of the multiple slave devices, so that the slave device that receives the slave service clearing message clears multiple services it is performing.

[0061] It should be noted that the same service is deployed on both the master device and the slave devices of the core server. When clearing the service on the master device, it is necessary to clear the service on the slave devices. Since when clearing the service, it may not be for all services, when clearing the service, it involves not only the master device but also some slave devices. Preferably, through the master service clearing message, determine the involved slave devices, then generate a slave service clearing message, and send the generated slave service clearing message to the involved slave devices. The slave device can identify the slave service clearing message and clear the relevant service according to the specific information it carries.

[0062] The method for clearing services provided by the embodiments of the present invention is applied to the master device in the core server. The core server further includes: multiple slave devices connected to the master device, and each slave device is connected to multiple terminal devices; the method includes: receiving a master service clearing message; according to the master service clearing message, clearing multiple services performed by the master device. By clearing multiple services performed by the master device, rapid clearing of a large number of services can be achieved, that is, clearing a large number of services in a short time and releasing the network bandwidth they occupy, so that there is sufficient bandwidth in the network to ensure the smooth progress of emergency services. According to the master service clearing message, send a slave service clearing message to at least one of the multiple slave devices, so that the slave device that receives the slave service clearing message clears multiple services it is performing. The same service is deployed on both the master device and the slave devices of the core server. When clearing the service on the master device and clearing the service on the slave devices at the same time, all relevant information of the cleared service can be ensured, and the service system can be prevented from reporting errors due to missing or inaccurate service information.

[0063] Based on the above embodiments of the invention, in the embodiments of the present invention, when the master service clearing message includes a first instruction, the step of clearing multiple services performed by the master device includes:

[0064] Obtain all data links in the core server;

[0065] Remove all data links and clear the service information on the master device.

[0066] It should be noted that when the master service clear message includes the first instruction, it means that all services in the core server are to be cleared. At this time, the master service clear message can be a command data packet containing the first operation code, a list of slave control devices, and a list of terminal devices. Both the list of slave control devices and the list of terminal devices are empty. The master device can parse the command data packet, identify the first operation code, obtain all the data links in the core server for the first operation code, and remove all the data links; at the same time, clear all the service information, such as deleting the meeting table.

[0067] Based on the above embodiments of the present invention, in the embodiments of the present invention, when the master service clear message includes the second instruction, the steps of clearing multiple services performed by the master device include:

[0068] Determine all the terminal devices connected to the target slave control device according to a preset device file; wherein, the preset device file stores the connection relationship between the master device and the slave control device and the connection relationship between the slave control device and the terminal device;

[0069] Obtain the data links corresponding to the determined terminal devices;

[0070] Remove the data links and clear the service information related to the target slave control device.

[0071] It should be noted that when the master service clear message includes the second instruction, it means that all the terminal devices under the specified slave control device are to exit the service. At this time, the master service clear message can be a command data packet containing the second operation code, a list of slave control devices, and a list of terminal devices. The list of slave control devices includes the identifier of the specified slave control device, and the identifier can be the Visual Networking number of the slave control device, but is not limited thereto. The list of terminal devices is empty. The master device can parse the command data packet and identify the second operation code. For the second operation code, obtain the data links corresponding to the terminal devices under the specified slave control device. Remove the obtained data links, and at the same time, clear the service information related to the specified slave control device, such as removing the terminal devices under the slave control device from the meeting list.

[0072] Based on the above embodiments of the present invention, in the embodiments of the present invention, when the master service clear message includes the third instruction, the steps of clearing multiple services performed by the master device include:

[0073] Obtain the data links corresponding to the target terminal device;

[0074] Remove the data links and clear the service information related to the target terminal device.

[0075] It should be noted that when the master control service clearing message includes the third instruction, it indicates that the specified terminal device is to be withdrawn from the service. At this time, the master control service clearing message can be a command data packet including a third operation code, a list of slave control devices, and a list of terminal devices. Among them, the list of slave control devices is empty, and the list of terminal devices includes the identifier of the specified terminal device, which can be the Visual Networking number of the terminal device, but is not limited thereto. The master control device can parse the command data packet and identify the third operation code. For the third operation code, obtain the data link corresponding to the specified terminal device. Remove the obtained data link, and at the same time clear the service information related to the specified terminal device, such as removing the specified terminal device from the conference list.

[0076] Based on the above embodiments of the present invention, in an embodiment of the present invention, when the master control service clearing message includes the first instruction, the step of sending a slave control service clearing message to at least one of the multiple slave control devices includes: sending a slave control service clearing message to each of the multiple slave control devices;

[0077] When the master control service clearing message includes the second instruction, the step of sending a slave control service clearing message to at least one of the multiple slave control devices includes: sending a slave control service clearing message to the target slave control device;

[0078] When the master control service clearing message includes the third instruction, the step of sending a slave control service clearing message to at least one of the multiple slave control devices includes: sending a slave control service clearing message to the slave control device connected to the target terminal device.

[0079] It should be noted that when the master control service clearing message includes the first instruction, it indicates that all services in the core server are to be cleared. At this time, it is necessary to notify all slave control devices connected to the master control device. When the master control service clearing message includes the second instruction, it indicates that all terminal devices under the specified slave control device are to be withdrawn from the service. At this time, the master control device only needs to notify the specified slave control device. When the master control service clearing message includes the third instruction, it indicates that the specified terminal device is to be withdrawn from the service. At this time, it also only needs to notify the slave control device connected to the specified terminal device.

[0080] Figure 2 FIG. shows a method for clearing services provided by an embodiment of the present invention, which is applied to a slave control device in a core server. The core server further includes: a master control device connected to the slave control device, and the slave control device is connected to multiple terminal devices; wherein the connections between the master control device and the slave control device and between the slave control device and the terminal devices are all communication connections, such as communication connections implemented through the Visual Networking or the Internet; the core server is connected to a service system and usually conducts a large number of services simultaneously.

[0081] The method for clearing services includes the following steps:

[0082] Step 201: Receive the sub-control service clearing message sent by the master control device;

[0083] It should be noted that the sub-control service clearing message is a message generated by the master control device based on the received master control service clearing message.

[0084] Step 202: Clear multiple services performed by the sub-control device according to the sub-control service clearing message.

[0085] It should be noted that the sub-control service clearing message includes: a first instruction for instructing to clear all services or a second instruction for instructing to clear the services performed by some terminal devices connected to the sub-control device. When the sub-control service clearing message includes the first instruction, it means that all terminal devices connected to the sub-control device need to exit the service. At this time, the sub-control device will clear all service information it stores, such as initializing the guiding table, initializing the door opening and closing information, etc. When the sub-control service clearing message includes the second instruction, it means that the specified terminal device exits the service, and the specified terminal device is some terminal devices connected to the sub-control device. At this time, the sub-control device will clear the service information related to the specified terminal device it stores, that is, update the relevant service information, such as updating the guiding table, door opening and closing information, etc.

[0086] Step 203: Send a terminal service clearing message to at least one of the multiple terminal devices according to the sub-control service clearing message, so that the terminal device that receives the terminal service clearing message clears the services it performs.

[0087] It should be noted that when the sub-control service clearing message includes the first instruction, it means that all terminal devices connected to the sub-control device need to exit the service. At this time, the sub-control device needs to notify all terminal devices connected to it. When the sub-control service clearing message includes the second instruction, it means that the specified terminal device exits the service, and the specified terminal device is some terminal devices connected to the sub-control device. At this time, the sub-control device only needs to notify the specified terminal device. Notifying the terminal device means sending a terminal service clearing message to the terminal device, so that the terminal device clears the service information on it, such as initializing the receiving channel information, initializing the sending channel information, etc. If the current terminal device is a speaker or a live source, stop sending audio and video data. After the terminal device finishes processing, it reports the processing result information to the sub-control device, the sub-control device returns the processing result information to the master control device, and finally the master control device returns the operation result to the control system.

[0088] The method for clearing services in the embodiments of the present invention is applied to a sub-control device in a core server. The core server further includes: a main control device connected to the sub-control device, and the sub-control device is connected to multiple terminal devices; the method includes: receiving a sub-control service clearing message sent by the main control device; wherein, the sub-control service clearing message is a message generated by the main control device according to the received main control service clearing message; according to the sub-control service clearing message, clearing multiple services carried out by the sub-control device. By clearing multiple services carried out by the sub-control device, rapid clearing of a large number of services can be achieved, that is, clearing a large number of services in a short time and releasing the network bandwidth occupied by them, so that there is sufficient bandwidth in the network to ensure the smooth progress of emergency services. According to the sub-control service clearing message, sending a terminal service clearing message to at least one of the multiple terminal devices, so that the terminal device receiving the terminal service clearing message clears the services it carries out. While clearing the services on the sub-control device, clearing the services on the terminal device can ensure all relevant information of the cleared services and avoid the service system from reporting errors due to missing or inaccurate service information.

Among them, the control system is connected to the core server through the Internet. The core server includes a main control device, a sub-control device connected to the main control device through the Visual Networking, and a terminal device connected to the sub-control device through the Visual Networking. The number of sub-control devices is multiple, Figure 5 only two are shown in the figure. Similarly, the number of terminal devices is also multiple. There are multiple core servers in the Visual Networking, and each core server is connected to the control system.

[0107] Based on the Figure 5 application architecture diagram shown, referring to Figure 6 it is the step flowchart of the method for clearing services provided by the embodiments of the present invention in the actual application scenario, which includes:

[0108] The control system connects to one or more core servers through TCP socket and logs in to the connected core servers using the root account registered in the core servers.

[0109] The control system sends an end service command packet to one or more specified core servers. The command packet information mainly includes: operation code (stop all services), sub-control device list (empty), and terminal device list (empty).

[0110] After receiving the command packet, the main control device parses it to obtain the service operation code, obtains all data links in the current core server for the service operation code and disassembles them. At the same time, it clears all service information (such as deleting relevant information such as the meeting table), and at the same time encapsulates and sends an end all services notification to all sub-control devices under this core server.

[0111] The sub-control devices that receive all service end notifications will clear all service information in the sub-control devices (such as initializing the orientation table, initializing the door opening and closing information, etc.), and at the same time notify all terminal devices under this sub-control device. After receiving the end service notification, the terminal device clears the service information on the terminal device (such as initializing the receiving channel information, initializing the sending channel information, etc.). If the current device is a speaking party or a live source, it stops sending audio and video data. After the terminal device finishes processing, it reports the processing result information to the sub-control device, the sub-control device returns the processing result information to the main control device, and finally the main control device returns the operation result to the control system.

[0112] When the command packet information mainly includes: operation code (all terminal devices under the sub-control device exit the service), sub-control device list (stores the sub-control device numbers), and terminal device list (empty), the master device obtains the information of all terminal devices under the current sub-control device from the device registration file according to the sub-control device numbers. Then, it obtains the corresponding data links of the terminal devices and disconnects them. At the same time, it clears the service information related to the sub-control device (such as updating relevant information like removing the terminal devices under the sub-control device from the meeting list, etc.), and at the same time encapsulates the end-of-sub-control-device service notification and sends it to all sub-control devices in the sub-control device list.

[0113] The sub-control device that receives the end-of-sub-control-device service notification clears all service information in the sub-control device (such as the orientation table, door opening and closing information, etc.), and at the same time notifies all terminal devices under the sub-control device. After receiving the end-of-service notification, the terminal device clears the service information on the terminal device (such as initializing the receiving channel information, initializing the sending channel information, etc.). If the current device is a speaking party or a live source, it stops sending audio and video data. After the terminal device finishes processing, it reports the processing result information to the sub-control device. The sub-control device returns the processing result information to the master device, and finally the master device returns the operation result to the control system.

[0114] When the command packet information mainly includes: operation code (specify a terminal device to exit the service), sub-control device list (empty), and terminal device list (stores the numbers of the terminal devices that need to end the service), the master device will obtain the corresponding data links of the terminal devices in the terminal device list and disconnect them. At the same time, it clears the relevant service information (such as updating relevant information like removing the terminal devices in the terminal device list from the meeting list, etc.), and at the same time encapsulates the end-of-device-service notification and sends it to the sub-control device corresponding to the terminal devices in the terminal device list.

[0115] The sub-control device that receives the end-of-device-service notification updates the corresponding service information in the sub-control device (such as the orientation table, door opening and closing information, etc.), and at the same time notifies the terminal devices in the terminal device list. After receiving the end-of-service notification, the terminal device clears the service information on the terminal device (such as initializing the receiving channel information, initializing the sending channel information, etc.). If the current device is a speaking party or a live source, it stops sending audio and video data. After the terminal device finishes processing, it reports the processing result information to the sub-control device. The sub-control device returns the processing result information to the master device, and finally the master device returns the operation result to the control system.
