Description

Technical Field

[0001] The present invention relates to the field of instant messaging technology, and in particular to a cross-network communication method, device and communication network. Background Art

[0002] In the office scenes of government and enterprise employees, connections are generally established through instant messaging tools, and instant messaging tools are used as information and data to complete mutual work collaboration. In order to ensure information security and data security, internal communication networks and external Internet networks are often isolated through private deployment.

[0077] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0078] The embodiment of the present invention provides a cross-network communication method, referring to Figure 1 , Figure 1 FIG. 1 is a flow chart of a first embodiment of the cross-network communication method of the present invention.

[0079] In this embodiment, the cross-network communication method includes the following steps:

[0080] Step S10: when there is an inter-network communication service in the local inter-network component, obtaining a service type corresponding to the inter-network communication service;

[0081] It should be noted that the execution subject of the cross-network communication method provided in this embodiment can be a privately deployed network (hereinafter referred to as a local network), which communicates and interacts with one or more other networks (i.e., external networks) through the cross-network communication method provided in this embodiment. Before executing this embodiment, it is necessary to pre-deploy the above-mentioned cross-network component in the local network and external network participating in the interaction. The component can be a specific component or service (such as a message queue MQ) that receives cross-network communication services, or other components or services that can achieve the same or similar functions.

[0082] It should be understood that the above-mentioned cross-network communication service may be a communication service that needs to be transmitted and collaboratively processed between the local network and the external network. In this embodiment, the service types of the cross-network communication service include internal-external cross-network communication service and external-internal cross-network communication service. Among them, the internal-external cross-network communication service may be a communication service that is transmitted from the local network to the external network and processed by the external network, and the external-internal cross-network communication service may be a communication service that is transmitted from the external network to the local network and processed by the local network.

[0083] Step S20: When the service type is an internal and external inter-network communication service, determining whether an inter-network connection has been established with the target external network;

[0084] It should be noted that the cross-network connection is a cross-network communication connection established in advance between the local network and the external network. In practical applications, the connection can be established based on the TCP protocol. The target external network can be the external network to which the cross-network communication service currently needs to be processed. For the local network, there can be one or more external networks, which is not limited in this embodiment.

[0085] It should be understood that if the cross-network connection has been established, it indicates that the local network and the external network have previously established a communication connection based on the custom handshake protocol; otherwise, it indicates that the cross-network connection needs to be established first.

[0086] As a method of determining the target external network, a network identification identifier can be added to the cross-network communication service in advance. The network identification identifier can represent the uniqueness of the network and is used to determine the external network to which the cross-network communication service points. Specifically, when the local network receives the cross-network communication service, it can first obtain the network identification identifier carried in the cross-network communication service; and then determine the target external network corresponding to the cross-network communication service based on the network identification identifier.

[0087] In a specific implementation, when the local network determines that the current inter-network communication service is an internal and external inter-network communication service according to the service type, and determines the target external network according to the network identification identifier, it can further determine whether the above-mentioned inter-network connection has been established with the target external network.

[0088] Step S30: If yes, the inter-network communication service is pushed to the target external network through the inter-network connection, so that the target external network processes the inter-network communication service through its own inter-network component.

[0089] It should be understood that when a cross-network connection has been established between the local network and the target external network, the local network can push the cross-network communication service to the target external network through the cross-network connection. Similarly, since the external network, like the local network, has pre-deployed the above-mentioned cross-network components, the local network pushes the above-mentioned internal and external cross-network communication services to the target external network through the above-mentioned cross-network connection, and the (own) cross-network components in the target external network process the cross-network communication services, thereby realizing communication between cross-networks.

[0090] This embodiment obtains the service type corresponding to the cross-network communication service when there is a cross-network communication service in the local cross-network component; when the service type is an internal and external cross-network communication service, it determines whether a cross-network connection has been established with the target external network; if so, the cross-network communication service is pushed to the target external network through the cross-network connection, so that the target external network processes the cross-network communication service through its own cross-network component. Since cross-network components for processing cross-network services are deployed in both the local network and the external network in this embodiment, the cross-network communication service can be logically isolated from the local communication service to ensure data security and information security. In addition, this embodiment transmits and processes communication services through cross-network components and cross-network connections, providing a safe and effective way for interaction between privately deployed networks.

[0091] refer to Figure 2 , Figure 2 FIG. 4 is a flow chart of a second embodiment of the cross-network communication method of the present invention.

[0092] Based on the first embodiment above, in this embodiment, before step S10, the following steps are further included:

[0093] Step S01: obtaining session information of a session to which a communication service to be processed belongs in a local cross-network component;

[0094] It should be noted that the communication services to be processed in this embodiment may include cross-network communication services and intranet communication services. The so-called cross-network communication services are communication services between different networks, including internal and external cross-network communication services and external and internal cross-network communication services. The so-called intranet communication services are communication services within the local network. These communication services do not need to be processed collaboratively with the help of an external network, and the processing of the entire communication service is carried out within the local network.

[0095] It should be understood that in the field of instant messaging, chat-type communication services are mostly presented in the form of sessions. In this embodiment, the above-mentioned session information may include the names of the participants in the session, the networks to which they belong, and the types of sessions, etc. Among them, the types of sessions may include local single-person sessions (single chat), local multi-person sessions (group chat), cross-network single chat, cross-network group chat, etc. Different types of session types may be used as one of the bases for determining whether the communication service to be processed belongs to an intranet communication service or a cross-network communication service.

[0096] Step S02: determining whether the communication service to be processed is an inter-network communication service according to the session information.

[0097] In a specific implementation, after obtaining the session information of the session (including a single-person session or a multi-person session) to which the communication service to be processed belongs, it can be determined whether the service belongs to a cross-network communication service according to the session information.

[0098] Specifically, to improve judgment efficiency and accuracy, in this embodiment, the local network may first determine the network identifier of the network to which each session participant belongs based on the session information, and then determine whether the communication service to be processed is a cross-network communication service based on the network identifier.

[0099] As an implementation method, the local network can determine whether there are different network identifiers in the network identifiers; if so, it is determined that the communication service to be processed belongs to an inter-network communication service; if not, it is determined that the communication service to be processed does not belong to an inter-network communication service.

[0100] It should be understood that single-person conversations include intranet single-person conversations and cross-network single-person conversations, and the way to distinguish between them can be determined by determining the network identifier of the network used by the two parties participating in the conversation. Usually, in an intranet single-person conversation, the network used by the two parties participating in the conversation is the same, and their corresponding network identifiers are also the same. At this time, it can be determined that the communication business to be processed does not belong to the cross-network communication business but to the intranet communication business; conversely, the network identifiers are different, indicating that the networks used by the two parties participating in the conversation are not the same, and at this time, it can be determined that the communication business to be processed belongs to the cross-network communication business. Among them, the network identifier can be the marking information that characterizes the uniqueness of the network.

[0101] As for a multi-person session, in this embodiment, when the session type is a multi-person session, the creation entry information of the multi-person session can be obtained, and then the communication service to be processed can be judged whether it is a cross-network communication service according to the creation entry information. Specifically, the session type of the session can be determined according to the session information, and when the session type is a multi-person session, the creation entry information of the session is obtained, and whether the communication service to be processed is a cross-network communication service can be judged according to the creation entry information.

[0102] It should be understood that an intranet multi-person session does not involve external personnel, while a cross-network multi-person session does involve external personnel. In this embodiment, when the client corresponding to the local network creates an intranet multi-person session and a cross-network multi-person session, its session creation portal is different, that is, the page controls or buttons that the user clicks on the client interface to create an intranet group chat and a cross-network group chat are different. Therefore, this embodiment obtains the creation portal information of the multi-person session, and then distinguishes whether the communication service to be processed initiated by the client belongs to a cross-network communication service or an intranet communication service based on the creation portal information.

[0103] Of course, in a multi-person conversation scenario, you can also first determine the network identifier of the network to which each session participant of the multi-person conversation belongs based on the session information of the multi-person conversation, and then judge whether the communication service to be processed belongs to a cross-network communication service based on whether these network identifiers are consistent; if the network identifiers are all the same, it can be determined that the communication service to be processed does not belong to a cross-network communication service (that is, it belongs to an intranet multi-person conversation); conversely, if there are different network identifiers among these network identifiers, it indicates that the networks used by the session participants are not the same, and at this time it can be determined that the communication service to be processed belongs to a cross-network communication service (that is, it belongs to a cross-network multi-person conversation).

[0104] Furthermore, when the communication service to be processed does not belong to an inter-network communication service, the local network determines that the communication service to be processed belongs to an intranet communication service; then obtains the service attributes of the communication service to be processed, and routes the communication service to be processed to the corresponding intranet service for processing according to the service attributes.

[0105] Among them, the above-mentioned intranet service is a service deployed in the local network, and the above-mentioned business attributes may refer to the prescribed characteristics of a certain telecommunications business, which is mostly used in the communication field.

[0106] It should be understood that the intranet communication service is the communication service related to the local network. When the received communication service is the intranet communication service, the local network can route the communication service to be processed to the corresponding intranet service for processing according to its corresponding service attributes.

[0107] This embodiment can accurately distinguish the service type of the communication service to be processed by acquiring the session information of the session to which the communication service to be processed belongs, and then process it in a targeted manner, thereby improving the processing efficiency of the communication service.

[0108] refer to Figure 3 , Figure 3 FIG. 4 is a flow chart of a third embodiment of the cross-network communication method of the present invention.

[0109] Based on the above embodiments, in this embodiment, after step S20, the method further includes a process of cross-network connection when a connection with the target external network is not established, specifically including:

[0110] Step S40: If not, obtaining a network access identifier and a communication encryption identifier corresponding to the target external network;

[0111] It should be understood that if a cross-network connection has not yet been established between the local network and the target external network, the local network can establish a cross-network connection through the network access identifier and communication encryption identifier that the administrator of the target external network has previously shared with the administrator of the local network.

[0112] It should be noted that the network access identifier may include: an IP address and a port number, and the communication encryption identifier includes a public key of an asymmetric encryption algorithm, such as an RSA public key.

[0113] Step S50: generating a connection request according to the network access identifier, and encrypting the connection request by using the communication encryption identifier to obtain an encrypted connection request;

[0114] In a specific implementation, the local network can initiate a connection request to the target external network through the above network access identifier, and then encrypt the request through the communication encryption identifier provided by the target external network to obtain an encrypted connection request, and then send the encrypted connection request to the target external network.

[0115] Step S60: Send the encrypted connection request to the target external network, so that the target external network establishes a cross-network connection after verifying the encrypted connection request.

[0116] It should be noted that, for an external network, when an encrypted connection request is received, the request can be decrypted using a communication decryption identifier. If the decryption succeeds, it indicates that the verification is successful, and the subsequent cross-network connection establishment operation can be performed.

[0117] Of course, in actual applications, the local network can be used as both the initiator and the receiver of the cross-network connection request. Therefore, the cross-network communication method provided in this embodiment also includes:

[0118] Step S1: upon receiving an inter-network connection request initiated by the target external network, obtaining a communication decryption identifier corresponding to the inter-network connection request;

[0119] Step S2: verifying the cross-network connection request through the communication decryption identifier;

[0120] It should be understood that the communication decryption identifier may be a private key corresponding to the communication encryption identifier, such as an RSA private key. Through the communication decryption identifier, when the local network receives a cross-network connection request sent by the external network, it will verify the cross-network connection request through the communication decryption identifier corresponding to the communication encryption identifier shared with the external network in advance.

[0121] Step S3: When the verification is passed, a selection prompt for establishing a cross-network connection is displayed on a preset interactive interface;

[0122] In the specific implementation, the local network decrypts the cross-network connection request through the communication decryption identifier. If the decryption is successful, a selection prompt for establishing a cross-network connection is displayed on a preset interactive interface. For example, a window pops up on the network management client page used by the administrator of the local network, prompting the administrator to choose "Agree" or "Reject" the cross-network connection request initiated by the target external network.

[0123] Step S4: when a confirmation instruction based on the selection prompt input is detected, establishing a cross-network connection with the external network.

[0124] In a specific implementation, when the administrator chooses to agree, that is, when the local network detects a confirmation instruction input based on the selection prompt, the cross-network connection is established with the external network. Conversely, when the administrator chooses to reject, that is, when the local network detects a rejection instruction input based on the selection prompt, the cross-network connection is stopped from being established with the external network.

[0125] Furthermore, if the local network fails to verify the cross-network connection request, it means that the source of the cross-network connection request cannot be identified. At this time, the cross-network connection request needs to be abandoned, and there is no need to make any interactive response on the interactive interface.

[0126] In addition, it should be emphasized that when the communication encryption identifier shared by the local network has been used by the corresponding external network, if a new external network needs to create a new cross-network connection with the local network, the network administrator of the local network is required to provide the network access identifier and the new communication encryption identifier to the new external network, and then create a new cross-network connection again according to the above handshake security mechanism (i.e., the above steps S1-S4).

[0127] Based on the above embodiments, a fourth embodiment of the cross-network communication method of the present invention is proposed.

[0128] In this embodiment, the local cross-network component is a message queue MQ. Accordingly, the cross-network communication method further includes the following steps:

[0129] Step S1': upon receiving a cross-network session creation request initiated by a client, generating a cross-network session creation event according to the cross-network session creation request;

[0130] It should be noted that the cross-network session creation request is a communication service request for creating a cross-network single chat or cross-network group chat. When the local network receives the request, the internal service cloud first processes the cross-network group creation logic. After the processing is completed, a cross-network session creation event is generated and a message of successful group creation is sent to the above-mentioned client.

[0131] Step S2': delivering the cross-network session creation event to the message queue for consumption;

[0132] In the specific implementation, the local network delivers the generated cross-network session creation event to the message queue MQ for consumption.

[0133] Step S3': when consuming the cross-network session creation event, the cross-network session creation event is pushed to the target external network through the established cross-network connection, so that the target external network processes the cross-network session creation event and completes the creation of the cross-network session.

[0134] It should be understood that when the message queue MQ deployed in the local network consumes the above-mentioned cross-network session creation event, since a cross-network connection has been established between the local network and the target external network, the local network can directly push the cross-network session creation event to the target external network through the cross-network connection. The external agent deployed in the target external network delivers the event to its own cross-network component (i.e., its own message queue) for consumption. During the consumption process, the internal agent in the target external network will call the business service, and the service cloud in the target external network will process the cross-cloud group creation logic, and push the session creation message to the client in the target external network to complete the creation of the cross-network session.

[0135] Further, after the cross-network session is created, users between the networks can chat through them. In this embodiment, the local network can deliver the session message sent by the target external network to the message queue for consumption, thereby pushing the session message to the corresponding session client.

[0136] As an implementation method, when a client in the target external network sends a cross-cloud group message (session message), the service cloud in the target external network will process the group chat logic of the local cloud and deliver the group message event to the internal agent in the target external network. The internal agent processes the delivery logic of the group message, delivers the group message event to its own message queue (MQ) for business message consumption, and passes it to the external agent in the target external network. The external agent sends the cross-cloud group message to the local network through a cross-network connection.

[0137] The external agent in the local network delivers the cross-cloud group message (session message) in the target external network to the local message queue (MQ) for consumption. The internal agent in the local network processes the call logic and sends the group chat message to the service cloud in the local network. The service cloud pushes the session message notification to the client in the local network, thereby completing the cross-network communication.

[0138] Reference Figure 4 , Figure 4 FIG. 1 is a structural block diagram of a first embodiment of a communication network according to the present invention.

[0139] like Figure 4 As shown, an embodiment of the present invention provides a communication network 10, in which an internal agent 101, a cross-network component 102 and an external agent 103 are deployed;

[0140] The internal agent 101 is used to obtain the service type corresponding to the inter-network communication service when receiving the inter-network communication service;

[0141] The internal agent 101 is further used to deliver the cross-network communication service to the cross-network component when the service type is an internal and external cross-network communication service;

[0142] The cross-network component 102 is used to send the cross-network communication service to the external agent;

[0143] The external agent 103 is used to determine whether an inter-network connection has been established with the target external network corresponding to the inter-network communication service;

[0144] The external agent 103 is further configured to, if yes, push the inter-network communication service to the target external network through the inter-network connection, so that the target external network processes the inter-network communication service through its own inter-network component.

[0145] It should be noted that the communication network 10 provided in this embodiment may be a privately deployed network or a private cloud, in which an internal agent 101, a cross-network component 102 and an external agent 103 are provided. Figure 5 As shown, Figure 5 FIG. 1 is a schematic diagram of a system architecture of a communication network in a first embodiment of the communication network of the present invention. Figure 5 In the embodiment, the system architecture of the first network, the second network and more networks are the same as the architecture of the communication network 10 provided in this embodiment, including an internal agent 101, a cross-network component 102 and an external agent 103. It also includes several access gateways and different types of databases (MySQL, MongoDB, Redis, ES and OSS). When the first network is used as a local network, the second network and more networks belong to the external network. When the local network communicates with the external network across networks, the internal agent 101, the cross-network component 102 and the external agent 103 cooperate with each other to complete the processing of the communication business.

[0146] Among them, the internal agent 101 is used to connect to the communication services within the network, such as internal single chat, group chat, personnel management services, etc. When the internal agent 101 receives the business related to the internal cloud, it delivers the business to the internal processing, and is responsible for processing the communication business from the outside. The cross-network component 102 can be a specific component or service (such as message queue MQ) that receives cross-cloud / cross-network communication services, or other components or services that can achieve the same or similar functions. The external agent 103 is used to deliver the cross-cloud / cross-network communication services involved in the communication services within the private cloud to the cross-network components in the other network through the external agent in the other network, and at the same time, the cross-cloud communication services pushed by the other network through the other external agent are delivered to the cross-network components within the cloud, and after consumption, they are routed to different services according to business attributes through the internal agent 101.

[0147] It should be understood that the above-mentioned cross-network communication service may be a communication service that needs to be transmitted and collaboratively processed between the local network and the external network. In this embodiment, the service types of the cross-network communication service include internal-external cross-network communication service and external-internal cross-network communication service. Among them, the internal-external cross-network communication service may be a communication service that is transmitted from the local network to the external network and processed by the external network, and the external-internal cross-network communication service may be a communication service that is transmitted from the external network to the local network and processed by the local network.

[0148] It should be noted that the above cross-network connection is a cross-network communication connection established in advance between the local network and the external network. In practical applications, the connection can be established based on the TCP protocol. The target external network can be the external network to which the cross-network communication service currently needs to be processed. For the local network, there can be one or more external networks, which is not limited in this embodiment.

[0149] In a specific implementation, if the cross-network connection has been established, it indicates that the local network and the external network have previously established a communication connection based on a custom handshake protocol; otherwise, it indicates that a cross-network connection needs to be established first.

[0150] As a method of determining the target external network, a network identification identifier can be added to the cross-network communication service in advance. The network identification identifier can represent the uniqueness of the network and is used to determine the external network to which the cross-network communication service points. Specifically, when the local network receives the cross-network communication service, it can first obtain the network identification identifier carried in the cross-network communication service; and then determine the target external network corresponding to the cross-network communication service based on the network identification identifier.

[0151] It should be understood that when a cross-network connection has been established between the local network and the target external network, the local network can push the cross-network communication service to the target external network through the cross-network connection. Similarly, since the external network, like the local network, has pre-deployed the above-mentioned cross-network components, the local network pushes the above-mentioned internal and external cross-network communication services to the target external network through the above-mentioned cross-network connection, and the (own) cross-network components in the target external network process the cross-network communication services, thereby realizing communication between cross-networks.

[0152] When the internal agent in the communication network provided by this embodiment receives the cross-network communication service, it obtains the service type corresponding to the cross-network communication service, and when the service type is internal and external cross-network communication service, it delivers the cross-network communication service to the cross-network component; the cross-network component sends the cross-network communication service to the external agent; the external agent determines whether a cross-network connection has been established with the target external network corresponding to the cross-network communication service; if so, the cross-network communication service is pushed to the target external network through the cross-network connection, so that the target external network processes the cross-network communication service through its own cross-network component. Since the communication network of this embodiment is deployed with a cross-network component for processing cross-network services, the cross-network communication service can be logically isolated from the local communication service to ensure data security and information security. In addition, this embodiment transmits and processes communication services through cross-network components and cross-network connections, providing a safe and effective way for interaction between privately deployed networks.

[0153] Based on the above-mentioned first embodiment of the communication network of the present invention, a second embodiment of the communication network of the present invention is proposed.

[0162] The external agent 103 is further used to generate a connection request according to the network access identifier, and encrypt the connection request through the communication encryption identifier to obtain an encrypted connection request;

[0163] The external agent 103 is further configured to send the encrypted connection request to the target external network, so that the target external network can establish a cross-network connection after verifying the encrypted connection request.

[0167] The internal agent 101 is further used to deliver the cross-network session creation event to the cross-network component for consumption;

[0168] The cross-network component 102 is further configured to transmit the cross-network session creation event to the external agent;

[0169] The external agent 103 is further used to push the cross-network session creation event to the target external network through the established cross-network connection, so that the target external network processes the cross-network session creation event and completes the creation of the cross-network session.

[0178] Step 301: A client in the first network (communication network 10) initiates a service request to create a cross-cloud group chat; the service cloud in the first network processes the cross-cloud group creation logic; after the processing is completed, a cross-cloud group creation event is pushed to the internal agent in the first network, and a notification of successful group creation is sent to the client in the first network.

[0179] Step 302: After receiving the cross-cloud group creation event, the internal agent in the first network processes the cross-cloud delivery logic and delivers the cross-cloud group creation event to the message queue (MQ) service in the first network.

[0189] Step 312: The external agent in the first network delivers the service message (group chat message) in the second network to the message queue (MQ) in the first network.

[0190] Step 313: The message queue (MQ) in the first network consumes the service message (group chat message), the internal proxy in the first network processes the call logic, and sends the group chat message to the service cloud in the first network.
