Description

Technical Field

[0001] The present invention belongs to the field of communication interface technology, and in particular to a method for defining a routing terminal and a generalized radio station interface based on the Hongmeng system. Background Art

[0002] When a generalized radio station (SDR) senses that a new generalized radio station device has been connected to / disconnected from the network in the surrounding area, it will notify the routing terminal (routing terminal) of the newly connected / disconnected routing terminal device IP. The interface between the routing terminal and the generalized radio station obtains this information through the subscription and publishing service. The generalized radio station acts as a publisher, and the corresponding routing terminal of its connected device acts as a subscriber. When a generalized radio station senses that a new generalized radio station device has been connected to / disconnected from the network in the surrounding area, it publishes the IP information of the newly connected / disconnected device to its subscribers; when a routing terminal or a device directly connected to the generalized radio station no longer pays attention to the network status of the newly connected / disconnected routing terminal, it can send a cancellation subscription message to the generalized radio station to which it is connected. In the prior art, since the routing terminal only supports local area network device information synchronization, it does not support device information synchronization in cross-network mode. Summary of the invention

[0003] In response to the above technical problems, the present invention proposes a solution for defining a routing terminal and a generalized radio station interface based on the Hongmeng system.

[0004] The first aspect of the present invention proposes a method for defining a routing terminal and a generalized radio station interface based on the Hongmeng system, in which:

[0005] The routing terminal is equipped with Hongmeng system. Based on the native system, the soft bus system is customized and modified to add the publish-subscribe interface definition function with SDR to achieve information synchronization between routing terminals and downstream devices of different SDRs across networks;

[0006] The router terminal side implements the interface with the SDR, which includes three submodules: service management submodule, message encapsulation / decapsulation submodule, and TCP / UDP submodule;

[0007] The service management submodule implements the business logic of managing broadcast services, subscription and publishing services, and unsubscription services with the SDR interface;

[0008] The message encapsulation / decapsulation submodule implements the encapsulation and decapsulation of various messages according to the defined message format. The message header has a fixed length of 4 bytes and is encapsulated in the form of byte data stream, and the Payload part is encapsulated in Json format.

[0009] The TCP / UDP submodule implements TCP / UDP Socket transmission;

[0010] Through the above three sub-modules, the broadcast service and SDR negotiation port process, subscription service process, receiving and publishing service process, and unsubscription service process are implemented on the routing terminal side.

[0011] According to the method of the first aspect of the present invention, the broadcast service and SDR negotiation port process includes:

[0012] When the routing terminal detects that the interface directly connected to the SDR is LinkUp, the service management submodule triggers the broadcast service to send a broadcast service message to negotiate the IP and port information with the SDR; the broadcast service message is transmitted in UDP based on a known port and waits for the unicast response message from the peer SDR;

[0013] When the created UDP Sockt receives a message, it determines whether it is a unicast response message based on the type field in the message header. If it is, it parses the Payload according to the unicast response message format to obtain the IP and port information of the peer SDR reply; if not, no processing is required and the message is discarded.

[0014] According to the method of the first aspect of the present invention, the subscription service process includes:

[0015] After obtaining the IP and port information of the peer SDR, the service management submodule starts the subscription service process. The subscription request message is transmitted based on TCP. The routing terminal, as the client, establishes a TCP connection with the peer SDR based on the obtained IP and port information. After the TCP connection is successfully established, it triggers the sending of the subscription request message, completes the encapsulation of the subscription request message and sends it out through TCPSocket, and waits for the peer SDR to reply with a subscription response message.

[0016] When the created TCP Socket receives a message, it determines whether it is a subscription response message according to the type of the field indicated in the message header. If it is, it parses the Payload according to the subscription response message format and obtains the status code Status. A status code of 0 indicates that the subscription service process is successful, otherwise it fails.

[0017] According to the method of the first aspect of the present invention, the process of receiving the publishing service includes:

[0018] When the subscription service process is completed, the status code Status received in the subscription response message is 0. After the subscription is successful, wait for receiving TCP Socket messages;

[0019] Determine whether it is a publish message according to the type of the field indicated in the parsed message header. If it is a publish message, extract the Payload and obtain the OnlineIpList or OfflineIpList.

[0020] If it is OnLineIpList, the cross-network discovery process is triggered to the cross-network discovery module; if it is OfflineIpList, the offline processing process is triggered to the networking module.

[0021] According to the method of the first aspect of the present invention, the process of cancelling the subscription service includes:

[0022] The trigger condition for sending the unsubscribe request message is an external application behavior call, which is initiated when the routing terminal is not connected to the network or the radio station directly connected to the routing terminal does not communicate with other radio stations; the unsubscribe service process includes sending the unsubscribe request message and receiving the unsubscribe response;

[0023] When the created TCP Socket receives a message, it determines whether it is a cancel subscription response message according to the type of the field indicated in the message header. If it is, it parses the Payload according to the subscription response message format, and closes the previously created subscription and publishing TCP Socket, and no longer listens to the publishing message sent by the SDR.

[0024] The second aspect of the present invention proposes a device for defining an interface between a routing terminal and a generalized radio station based on the Hongmeng system. The routing terminal is loaded with the Hongmeng system. On the basis of the native system, the soft bus system is customized and modified to add a publish-subscribe interface definition function with the SDR to achieve information synchronization between routing terminals and downstream devices of different SDRs across networks; the routing terminal side implements an interface with the SDR, and the device includes three submodules: a service management submodule, a message encapsulation / decapsulation submodule, and a TCP / UDP submodule; wherein:

[0025] The service management submodule implements the business logic of managing broadcast services, subscription and publishing services, and unsubscription services with the SDR interface;

[0026] The message encapsulation / decapsulation submodule implements the encapsulation and decapsulation of various messages according to the defined message format. The message header has a fixed length of 4 bytes and is encapsulated in the form of byte data stream, and the Payload part is encapsulated in Json format.

[0027] The TCP / UDP submodule implements TCP / UDP Socket transmission;

[0028] Through the above three submodules, the device implements the broadcast service and SDR negotiation port process, subscription service process, receiving and publishing service process, and unsubscription service process on the routing terminal side.

[0029] According to the device of the second aspect of the present invention, the broadcast service and SDR negotiation port process includes:

[0030] When the routing terminal detects that the interface directly connected to the SDR is LinkUp, the service management submodule triggers the broadcast service to send a broadcast service message to negotiate the IP and port information with the SDR; the broadcast service message is transmitted in UDP based on a known port and waits for the unicast response message from the peer SDR;

[0031] When the created UDP Sockt receives a message, it determines whether it is a unicast response message based on the type field in the message header. If it is, it parses the Payload according to the unicast response message format to obtain the IP and port information of the peer SDR reply; if not, no processing is required and the message is discarded.

[0032] According to the device of the second aspect of the present invention, the subscription service process includes:

[0033] After obtaining the IP and port information of the peer SDR, the service management submodule starts the subscription service process. The subscription request message is transmitted based on TCP. The routing terminal, as the client, establishes a TCP connection with the peer SDR based on the obtained IP and port information. After the TCP connection is successfully established, it triggers the sending of the subscription request message, completes the encapsulation of the subscription request message and sends it out through TCPSocket, and waits for the peer SDR to reply with a subscription response message.

[0034] When the created TCP Socket receives a message, it determines whether it is a subscription response message according to the type of the field indicated in the message header. If it is, it parses the Payload according to the subscription response message format and obtains the status code Status. A status code of 0 indicates that the subscription service process is successful, otherwise it fails.

[0035] According to the device of the second aspect of the present invention, the process of receiving the publishing service includes:

[0036] When the subscription service process is completed, the status code Status received in the subscription response message is 0. After the subscription is successful, wait for receiving TCP Socket messages;

[0037] Determine whether it is a publish message according to the type of the field indicated in the parsed message header. If it is a publish message, extract the Payload and obtain the OnlineIpList or OfflineIpList.

[0038] If it is OnLineIpList, the cross-network discovery process is triggered to the cross-network discovery module; if it is OfflineIpList, the offline processing process is triggered to the networking module.

[0039] According to the device of the second aspect of the present invention, the process of canceling the subscription service includes:

[0040] The trigger condition for sending the unsubscribe request message is an external application behavior call, which is initiated when the routing terminal is not connected to the network or the radio station directly connected to the routing terminal does not communicate with other radio stations; the unsubscribe service process includes sending the unsubscribe request message and receiving the unsubscribe response;

[0041] When the created TCP Socket receives a message, it determines whether it is a cancel subscription response message according to the type of the field indicated in the message header. If it is, it parses the Payload according to the subscription response message format, and closes the previously created subscription and publishing TCP Socket, and no longer listens to the publishing message sent by the SDR.

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0059] The routing terminal described in the present invention is loaded with the Hongmeng system. Based on the native system, the soft bus system is customized and modified to add the publish-subscribe interface definition function with the SDR to realize the information synchronization of the routing terminals and the downstream devices under different SDRs (i.e. across networks).

[0060] like Figure 1-2 As shown, the router terminal side implements the interface with the SDR, and three sub-modules are designed: service management, message encapsulation / decapsulation, and TCP / UDP. The service management is responsible for implementing the business logic of managing the broadcast service, subscription and publishing service, and unsubscription service of the SDR interface; the message encapsulation / decapsulation sub-module is responsible for implementing the encapsulation and decapsulation of various messages according to the defined message format, in which the fixed length of the message header occupies 4 bytes, is encapsulated in the form of byte data stream, and the Payload part is encapsulated in Json format; the TCP / UDP sub-module is responsible for implementing TCP / UDP Socket transmission. Through these three sub-modules, the router terminal side realizes: the process of negotiating the port between the broadcast service and the SDR, the process of subscribing to the service, the process of receiving and publishing the service, and the process of unsubscribing the service.

[0061] 1. Broadcast service negotiation port process

[0062] 1) When the router detects that the interface directly connected to the SDR is LinkUp, the service management module triggers the broadcast service to send a broadcast service message to negotiate the IP and port information with the SDR. The broadcast service message is transmitted in UDP based on a known port, and then waits for the unicast response message from the peer SDR.

[0063] 2) When the UDP Sockt created above receives a message, it determines whether it is a unicast response message based on the type field in the message header. If it is, it parses the Payload according to the unicast response message format to obtain the IP and port information of the peer SDR reply; if not, no processing is required and the message is discarded.

[0064] 2. Subscription Service Process

[0065] 1) After obtaining the IP and port information of the peer SDR, the service management module will start the subscription service process. The subscription request message is based on TCP transmission. The routing terminal, as the client, establishes a TCP connection with the peer SDR based on the IP and port information obtained previously. After the TCP connection is successfully established, it triggers the sending of the subscription request message, completes the encapsulation of the subscription request message and sends it out through the TCP Socket, and then waits for the peer SDR to reply with a subscription response message.

[0066] 2) When the TCP Socket created earlier receives a message, it determines whether it is a subscription response message based on the type of the field indicated in the message header. If it is, it parses the Payload according to the subscription response message format to obtain the Status. If the status code is 0, it means that the subscription service process is successful, otherwise it fails.

[0067] 3. Release service process

[0068] When the subscription service process is completed, the Status in the received subscription response message is 0. After the subscription is successful, it waits to receive the TCPSocket message, and determines whether it is a publishing message according to the type of the indicated field in the parsed message header. If it is a publishing message, the Payload is taken out to obtain the OnlineIpList or OfflineIpList. If it is the OnLineIpList, the cross-network discovery process is triggered to the cross-network discovery module; if it is the OfflineIpList, the offline processing process is triggered to the networking module.

[0069] 4. Unsubscribe process

[0070] 1) The trigger condition for sending the unsubscribe request message is an external application behavior call, such as when the router terminal does not want to access the network or the radio station directly connected to the router terminal does not communicate with other radio stations. These scenarios can be called. The unsubscribe service process also includes sending an unsubscribe request message and receiving an unsubscribe response.

[0071] 2) When the previously created TCP Socket receives a message, it determines whether it is a cancel subscription response message based on the type of the field indicated in the message header. If it is, it parses the Payload according to the subscription response message format, and closes the previously created subscription and publishing TCP Socket, and no longer listens to the publishing message sent by the SDR.

[0072] In the present invention: the routing terminal can detect the LinkUp and LinkDown of the interface directly with the SDR;

[0073] The routing terminal sends a broadcast service message to the SDR based on the IP and port corresponding to the broadcast service negotiation; the routing terminal receives and parses the unicast response message replied by the SDR to obtain the IP and port of the SDR; the routing terminal establishes a TCP connection based on the port negotiated by the broadcast, and sends a subscription request message to the SDR; the routing terminal receives and parses the subscription response message replied by the SDR; the routing terminal supports the connection between the routing terminal and the SDR, and supports the reception of the IP information of the routing terminal newly connected to the network by notification report issued by the SDR; the routing terminal supports the connection between the routing terminal and the SDR, and supports the reception of the IP information of the routing terminal disconnected from the network by notification report issued by the SDR; the routing terminal sends a cancellation request message to the SDR, and no longer pays attention to and monitors the network status information; the routing terminal parses the cancellation response message replied by the SDR; the message format of the transmission between the routing terminal and the SDR generally includes two parts, such as Figure 3 As shown, one part is the message header, which has a fixed length of 4 bytes, and the other part is the Payload, and the content of the Payload varies with the type of the message header.

On the basis of the native system, the soft bus system is customized and modified to add a publish-subscribe interface to communicate with the SDR, so as to achieve a method for synchronizing device information across networks.
