Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flow chart of a message communication method according to an embodiment of the application, as shown in fig. 1, including the following steps:
step 101, receiving an uplink message sent by a terminal.
The uplink message may be a message for triggering transmission of a downlink message to be transmitted, for example: uplink messages processed by the terminal service, uplink messages activated by the terminal, and the like.
Step 102, obtaining the terminal identification corresponding to the terminal according to the uplink message.
Step 103, inquiring whether a downlink message to be sent corresponding to the terminal identification is stored or not based on the terminal identification.
The downlink message to be sent may be a pre-stored downlink message to be sent, for example: a command message for turning on or off the lamp of the lamp, a command message for adjusting the brightness of the lamp, a command message for timing on-off of the current by the socket, etc.
Step 104, if the sending trigger condition of the downlink message to be sent is met under the condition that the downlink message to be sent corresponding to the terminal identification is inquired and stored, the downlink message to be sent is sent to the terminal.
The sending trigger condition may be a preset message sending trigger condition, for example: setting that the downlink message to be sent takes effect at a certain time as the sending triggering condition, and if the current time meets the effective time, sending the downlink message to be sent to the terminal.
In this embodiment, the on-line state of the terminal may be determined by receiving the uplink message sent by the terminal, and the terminal identifier may be obtained through the uplink message, and the pre-stored downlink message to be sent corresponding to the terminal may be queried based on the terminal identifier, and the downlink message to be sent may be sent to the terminal, so that asynchronous communication of the downlink message to be sent may be implemented, and thus a technical effect of improving a communication effect may be implemented.
In addition, in the prior art, the command issuing under NB-IoT (Narrow Band Internet of Things ) scenario generally determines whether the terminal device is online through Socket (Socket) on the access platform, and when the device is not online under some scenarios, the message cannot be issued to the terminal device smoothly, for example: when a user sends a downlink message to the terminal through an upper layer application platform, the terminal is in a PSM (Power Saving Mode ), and then the terminal does not receive downlink data when in deep dormancy, only the terminal can receive downlink data when actively sending uplink data, and the downlink message to be sent corresponding to the terminal is obtained by receiving the uplink message sent by the terminal, so that the terminal can be ensured to receive the downlink message to be sent corresponding to the terminal.
Optionally, after the downlink message to be sent is sent to the terminal in step 104, the method may further include:
receiving a response message sent by the terminal to the downlink message to be sent;
And sending the response message to a preset network address.
The preset network address may be a network address preset by a user, for example: and pushing the response message on a URL (Uniform Resource Locator ) set by a user in an http/https mode.
In this embodiment, the response message sent by the terminal to the downlink message to be sent is sent to a preset network address, and the response state of the terminal to the downlink message to be sent can be monitored in real time through the preset network address.
Optionally, in step 103, the querying, based on the terminal identifier, whether the downlink message to be sent corresponding to the terminal identifier is stored may specifically include:
Inquiring whether index information corresponding to the terminal identification exists or not through a remote dictionary service;
Under the condition that index information corresponding to the terminal identification exists, detecting whether a sending triggering condition of a downlink message to be sent corresponding to the index information is met or not;
In step 104, if the sending trigger condition of the downlink message to be sent is met, sending the downlink message to be sent to the terminal may specifically include:
if the transmission triggering condition of the downlink message to be transmitted corresponding to the index information is met, acquiring the downlink message to be transmitted corresponding to the index information based on the index information;
And sending the downlink message to be sent to the terminal.
The index information may be information stored in advance, for example: and storing index information of the downlink message to be sent in a Redis (Remote Dictionary Server, remote dictionary service), automatically sequencing the index information through the remote dictionary service, and inquiring whether the index information of the downlink message to be sent corresponding to the terminal identification exists or not. In addition, the downlink message to be sent may be stored in a database in advance, and when the index information satisfies a sending trigger condition of the downlink message to be sent, the downlink message to be sent in the database may be obtained, and the downlink message to be sent may be sent to the terminal.
In this embodiment, by querying whether index information corresponding to the terminal identifier exists through the remote dictionary service, automatic ordering of the index information can be achieved, and query pressure when whether a downlink message to be sent corresponding to the terminal identifier is stored in the query is reduced.
Optionally, before the receiving the uplink message sent by the terminal in step 101, the method may further include:
Acquiring a downlink message to be sent corresponding to the terminal, and determining a sending triggering condition corresponding to the downlink message to be sent;
storing the downlink message to be sent, and acquiring index information of the downlink message to be sent;
And storing the corresponding relation between the terminal identification and the index information through a remote dictionary service.
The downlink message to be sent may be stored in a database, for example: and storing the downlink message to be sent in a MongoDB database, and acquiring the downlink message to be sent corresponding to the index information according to the index information under the condition that the index information corresponding to the terminal is inquired through the corresponding relation between the Redis storage terminal and the index information.
The terminal identifier may correspond to a plurality of index information, for example: the stored downlink messages to be sent comprise downlink message A, downlink message B and downlink message C, the corresponding relation between the downlink message A and the terminal 1, the corresponding relation between the downlink message B and the terminal 2 and the corresponding relation between the downlink message C and the terminal 1 can be stored through Redis, when the index information of the downlink message to be sent corresponding to the terminal 1 is queried, the index information of the downlink message A and the index information of the downlink message C can be obtained respectively, and then the downlink message A and the downlink message C are obtained according to the index information of the downlink message A and the index information of the downlink message C, and the downlink message A and the downlink message C are sent to the terminal 1.
In this embodiment, according to the terminal identifier obtained from the uplink message sent by the terminal, the index information of the downlink message to be sent corresponding to the terminal is quickly queried through the corresponding relationship between the terminal identifier and the index information stored by the remote dictionary service, so that the query of direct database storage messages is reduced, and the query pressure of the database can be reduced.
Optionally, the sending triggering condition includes a retry number, and after the sending the downlink message to be sent to the terminal in step 104, the method may further include:
And under the condition that the response message of the downlink message to be sent, which is sent by the terminal, is not received, judging whether to send the downlink message to be sent to the terminal again according to the retry times.
The foregoing failure to receive the response message sent by the terminal to the downlink message to be sent may be understood as failure to receive the response message sent by the terminal to the downlink message to be sent within a preset period, where in this embodiment, by determining whether to send the downlink message to be sent to the terminal again according to the retry number when the failure to receive the response message sent by the terminal to the downlink message to be sent is not received, the control capability of the downlink message to be sent may be improved.
Optionally, the sending triggering condition includes an effective time and an effective time, and in step 104, if the sending triggering condition of the downlink message to be sent is met, the sending the downlink message to be sent to the terminal may specifically include:
And under the condition that the current time is detected to meet the effective time, if the current time is determined to meet the effective time, sending the downlink message to be sent to the terminal.
The effective time and the valid time may be determined according to a usage scenario of the terminal, for example: for the lamp turn-on command of the lamp bulb, the effective time can be set to 7 pm, and the effective time is 7 pm to 9 pm on the same day, in this embodiment, by detecting the effective time and the effective time of the downlink message to be sent, it is determined whether to send the downlink message to be sent to the terminal, and the sending trigger condition of the downlink message to be sent can be set according to the usage scenario of the terminal in a self-defining manner, so as to enhance the control capability of the downlink message to be sent.
Optionally, before the sending the downlink message to be sent to the terminal in step 104, the method may further include:
Receiving a cancel sending instruction of a user to the downlink message to be sent;
And responding to the cancellation sending instruction, canceling sending the downlink message to be sent to the terminal.
In this embodiment, by receiving a cancel sending instruction of the user to the downlink message to be sent, and in response to the cancel sending instruction, canceling sending the downlink message to be sent to the terminal, a command to be sent can be controlled according to the cancel sending instruction of the user, and the control capability of the user to send the downlink message can be improved.
Fig. 2 is a schematic structural diagram of a message communication apparatus provided in an embodiment of the present application, as shown in fig. 2, an apparatus 200 includes a NBIoT-api (Narrow Band Internet of Things-Application Programming Interface, internet of things-application program interface) module 201, session (session control) module 202, dis203, mongoDB (database) 204, NBIoT-acc (Narrow Band Internet of Things-access) module 205, NBIoT-cmd Narrow Band Internet of Things-command, internet of things-control) module 206, datapush (data push) module 207 and kafka208, and as a specific embodiment, the message communication method may be used in the message communication apparatus 200, including the following procedures:
NBIoT-api module 201 receives a message to be issued, analyzes parameter information of the issued message, and verifies validity of the message, wherein the parameter information comprises effective time, effective time and retry times;
storing the issued message in a mongo db204, and storing index information and effective time corresponding to the issued message in a Redis 203;
NBIoT-acc module 205 receives the uplink message sent by the terminal, sends the uplink message to Kafka 208 according to a certain message format, and caches the address of NBIoT-acc module 205 to session module 202;
NBIoT-cmd module 206 pulls the uplink message in Kafka208, acquires the terminal identifier according to the uplink message, queries whether index information of a downlink message corresponding to the terminal identifier exists in Redis203 according to the terminal identifier, if so, performs the next process, and if not, sleeps the message downlink channel of the terminal for a certain time;
Under the condition that index information of a down message corresponding to the terminal identifier exists in the Redis203, acquiring a first effective command of the down message, detecting effective time of the down message, deleting the index information of the down message in the Redis203 and updating the state of the down message in the MongoDB204 if the down message is outdated, detecting effective time of the down message, and carrying out the next process if the effective time and the effective time are both satisfied, otherwise, dormancy of a message down channel of the terminal for a certain time;
Under the condition that the effective time and the effective time are both met, NBIoT-cmd module 206 acquires the downlink message in MongoDB according to the index information of the downlink message, inquires the session module 202 about the address of NBIoT-acc module 205 corresponding to the terminal, sequences the downlink message according to a certain format, and transmits the downlink message to NBIoT-acc module 205 in a communication mode through RPC (Remote Procedure Call );
NBIoT-acc module 205 sends the downlink message to the terminal;
NBIoT-acc module 205 receives the response message of the down message sent by the terminal, and sends the response message to NBIoT-cmd module 206;
NBIoT-cmd module 206 determines whether the transmission is successful and whether the next retry is required according to the response information;
NBIoT-cmd module 206 stores the response message in mongo db204 and sends the final response of the outgoing message to kafka208;
datapush module 207 pulls the response message in kafka208 and sends the response message to the URL address set by the user.
The NBIoT-api module 201 may also provide a function of querying the status of a single or multiple outgoing messages and an outgoing history, so as to facilitate the user to monitor the status of the outgoing messages. In addition, the NBIoT-api module 201 may perform cancellation of the transmission message based on a cancellation command for the transmission message.
After the terminal accesses through NBIoT-acc module 205, the session module 202 may cache related information (such as subscription information) of the device and the address of the corresponding access module NBIoT-acc module 205.
Wherein, the NBIoT-cmd module 206 can be executed according to the following logic:
Judging whether a downlink channel of the terminal is activated by acquiring an uplink message of the terminal, inquiring whether index information of a downlink message corresponding to the terminal exists in Redis203 or not if the downlink channel is activated, continuously judging whether the downlink message corresponding to the terminal meets a trigger condition if the index information exists, acquiring the downlink message in MongoDB204 if the trigger condition is met, transmitting the downlink message to NBIoT-acc module 205 in an RPC communication mode, receiving response information of the terminal to the downlink message by NBIoT-acc module 205, and continuously transmitting the downlink message in series if the response is successful. In addition, if index information of the downlink message corresponding to the terminal does not exist in the dis203 or the triggering condition of the downlink message corresponding to the terminal is not satisfied, the downlink channel of the terminal is temporarily dormant, and if the triggering condition of the downlink message corresponding to the terminal is not satisfied, if the downlink message has expired, the transmission of the downlink message can be canceled.
In addition, the NBIoT-cmd module 206 and the NBIoT-acc module 205 communicate with each other through remote procedure call, so that the coupling degree between the modules can be reduced, the stability and iterative maintenance of the system can be improved, and the current limiting control and statistics on the command downlink can be facilitated.
The message received by the kafka208 uses the terminal identifier as a key word, so that the message of one terminal can be pulled by a certain node of the module, serial winding parts of a single terminal are ensured, and the overhead of a distributed lock is avoided. The above-described kafka208 may act as a middleware for asynchronous communication between modules, reducing the degree of coupling between modules.
In this embodiment, the message to be sent is stored in the mongo db204, the index information of the message to be sent is stored in the Redis203, and the sending of the message to be sent corresponding to the terminal is triggered by the uplink message sent by the terminal, so that asynchronous communication of the message to be sent can be achieved, the communication effect is improved, and the response message sent by the terminal is received by the NBIoT-acc module 205, so that the response message is pushed in real time, thereby facilitating the user to monitor the status of the message to be sent.
In addition, the uplink message of a single terminal is directed to a certain control module node through the message structure characteristic of the kafka208 assembly, the problem of locking in a distributed environment is skillfully solved, the index information of the issued message is sequentially cached in a Redis203 sequencing structure body to realize automatic sequencing, the dynamic serial issuing of the issued message can be realized, the database query pressure is effectively reduced, the decoupling between modules can be realized through the mode of kafka208 and RPC communication, the capacity expansion and the capacity expansion of the module node can be realized through adopting a distributed deployment scheme in a hot-pluggable manner, and the concurrency capacity and the expansibility of a service cluster can be improved.
