Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a communication system and a method for communicating between an information service system and a control service system.
Background
In a communication system, an information service system is used for realizing the combination of resource management and business aspects, receiving and processing multi-user business requests and processing complex business logic. The control service system can control the communication terminal, collect the state of the communication terminal and provide an external interface to interact with other services. The information service system and the control service system are independent from each other and respectively complete respective functions, interaction between the two service systems can be completed according to defined interfaces, more complex functions are completed in a combined mode, and the two service systems work cooperatively to complete various business functions. The two service systems need a bidirectional communication mode according to business requirements, and the simultaneous communication mode needs both synchronous communication and asynchronous communication.
In the prior art, the communication modes between the information service system and the control service system mainly include two types:
realizing inter-system communication based on remote calling mode
The WEB service (WebService) is a cross-language inter-system interaction standard, one party providing functions to the outside provides services in a HyperText Transfer Protocol (HTTP), and the calling end and the service end interact in a Simple Object Access Protocol (SOAP) manner.
And (II) a communication mode based on WebSocket.
In an Application Programming Interface (API) of the WebSocket, a browser and a server only need to perform a handshake action, and then a fast channel is formed between the browser and the server. The two can directly transmit data to each other, and the original browser/server (B/S) mode is changed. The existing WebSocket technology is generally applied to asynchronous communication between a browser and a server.
However, the prior art has the following disadvantages:
in the above manner of implementing inter-system communication based on the remote invocation manner, WebService is slow, and needs to do much work at an optimized speed, which is not suitable for a system with a large amount of data transmission. The Webservice realizes two-way communication, can only adopt client polling call, and cannot actively send data to the client, so that resources are consumed.
In the above communication modes of the WebSocket, the WebSocket is mostly used for communication between the browser and the system, and the communication of the WebSocket is an asynchronous communication mode, which cannot meet the requirements of both synchronous communication and asynchronous communication in the communication system.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The concept of synchronization and asynchrony as described in this specification will be explained first.
The synchronization means that when a process executes a request, if the request needs a period of time to return information, the process waits until the process receives the returned information and continues to execute.
The asynchronous process means that the process does not need to wait all the time, but continues to execute the following operation regardless of the states of other processes. When a message is returned, the system can inform the process to process, so that the execution efficiency can be improved.
Fig. 1 is a schematic structural diagram of a communication system according to an application scenario. Referring to fig. 1, the communication system of the present invention mainly includes an information service system 101 and a control service system 102.
In the application scenario described in figure 1,
the user 103 is configured to send a control request, and receive a result of the control request and a state change condition of the monitored terminal device.
The information service system 101 and the control service system 102 adopt two-way communication.
The information service system 101 uniformly receives the request of the user and manages all data information of the system; meanwhile, the control request of the user is forwarded to the control service system 102 according to the service configuration; receiving the control result, and receiving the state change of the terminal collected by the control service system 102; and notifies the user of the above information.
The control service system 102 is configured to control and monitor a state change of the terminal 104, collect a change state of the terminal 104, process a control request sent by the information service system 101, and send a control result of the terminal 104 and a state change automatically initiated by the terminal 104 to the information service system 101. The information service system 101 receives the information and forwards the information to the associated user 103.
The terminal 104 is the final monitoring and control target.
The present invention requires that the communication between the information service system and the control service system must be bidirectional communication according to the traffic demand. The bidirectional communication means that: the information service system and the control service system can simultaneously transmit data to each other. And, the communication between the information service system and the control service system is classified into two types: synchronous communication and asynchronous communication.
In a preferred embodiment, the information service system and the control service system directly adopt WebSocket to realize bidirectional communication.
WebSocket is a two-way communication protocol, and after connection is established, an information service system and a control service system can both actively send or receive data to each other. The information service system can send a control request to the control service system, and the control service system sends a response result of the control request and the monitored terminal state change to the information service system. The two-way communication between the two system services of the information service system and the control service system is realized.
WebSocket is also asynchronous communication, most commands can adopt an asynchronous communication mode, and if the commands are related commands, namely synchronous commands, new commands can be sent only after command execution results are obtained.
In the communication system of the present invention, two communication modes of synchronous communication and asynchronous communication need to be implemented in one path between the information service system and the control service system. According to the service requirement, for the control request without logic association, the information service system adopts an asynchronous mode to send to the control service system, and for the control request with logic association, the control request can enter different synchronous control request queues according to the system requirement and is sent to the information service system in a synchronous mode.
The information service system and the control service system have the characteristics of low coupling and easy expansion. For the control service system, only simple receiving of the control request, execution of the control request and collection of the terminal state information are needed, timing problems and business logic problems do not need to be considered, and namely, the control service system is not provided with a timing control module and a business logic module. The timing sequence and business logic problems are controlled at the information service system side in a centralized mode, namely the information service system comprises a timing sequence module and a business logic module, the business logic module of the information service system determines whether control requests are sent synchronously or asynchronously according to business types, and the timing sequence module is contained in a synchronous module and used for carrying out timing sequence control on synchronous control requests in a synchronous control request queue. The invention is convenient to expand when a new service is added. Due to the characteristics, the information service system and the control service system are relatively independent, the coupling is low, and the expansion is easy. When a business logic module needs to be added, the business logic module only needs to be added in the information service system, the control service system does not need to be added, and the WebSocket communication protocol between the systems does not need to be modified because the information service system only realizes the transmission of the synchronous control request through synchronous control, so the modification and updating cost is low.
The invention mainly discloses a communication method between an information service system and a control service system. The user sends a request to the information service system, and the information service system classifies the request according to the request type and is divided into a control request and an information management request.
For a control request, the information service system again determines the type of the control request. The method specifically comprises the following steps: the information service system will classify the control request into two categories according to the business model requirements: synchronous control requests and asynchronous control requests. After receiving the control request, the information service system divides the asynchronous control request and the synchronous control request according to the requirements of the service model, and judges whether the currently received control request is the asynchronous control request or the synchronous control request.
If the control request is an asynchronous control request, the information service system directly sends the asynchronous control request to the control service system without waiting for the execution result of the control service system to the asynchronous control request, after the control request is executed by the control service system, the control service system asynchronously transmits the control result to the information service system, and the information service system asynchronously receives the control result returned by the control service system.
If the synchronous control request is the synchronous control request, the information service system puts the synchronous control request into a synchronous control request queue corresponding to the service type of the synchronous control request according to the division of the service type of the synchronous control request, then sends the synchronous control request to the control service system according to the first-in first-out sequence for the synchronous control request in the synchronous control request queue, and sends the next synchronous control request in the synchronous control request queue to the control service system after receiving the control result of the synchronous control request returned by the control service system.
In a preferred embodiment, the synchronization control request queue has more than one, and the information service system puts the synchronization control requests of the same service type and having correlation with each other into the same synchronization control request queue.
Corresponding to the above method, in the communication system according to the present invention, the information service system includes the following modules:
the request judging module is used for receiving the control request and judging the type of the control request; if the request is an asynchronous control request, triggering an asynchronous module; if the request is a synchronous control request, triggering a synchronous module;
the asynchronous module is used for sending the asynchronous control request to a control service system and asynchronously receiving a control result returned by the control service system;
the synchronization module is used for putting the synchronization control request into a synchronization control request queue corresponding to the service type of the received synchronization control request according to the division of the service type of the synchronization control request, then sending the synchronization control request to the control service system according to the first-in first-out sequence for the synchronization control request in the synchronization control request queue, and sending the next synchronization control request in the synchronization control request queue to the control service system after receiving the control result of the synchronization control request returned by the control service system.
In a preferred embodiment, the request determining module is specifically configured to: and judging whether the currently received control request is an asynchronous control request or a synchronous control request according to the division of the asynchronous control request and the synchronous control request required by the service model.
In a preferred embodiment, the synchronization control request queue has more than one, and the synchronization module of the information service system is configured to place synchronization control requests of the same service type and having correlation with each other into the same synchronization control request queue.
Fig. 2 is a schematic flow chart of communication between the information service system and the control service system according to the present invention. Referring to fig. 2, the information service system and the control service system are in two-way communication.
The asynchronous communication specifically includes: the information service system collects various control and monitoring requirements of users and is responsible for sending control requests to the control service system. If the control request does not belong to the synchronous control request, the asynchronous control request is sent in an asynchronous communication mode, all the asynchronous control requests are sent to the control service system, after the control result is received from the control service system, the terminal state is recorded, the control result is forwarded to the user according to the unique identification of the control request, and the user and the information service system directly adopt the WebSocket mode for asynchronous communication.
For example, as shown in fig. 2, if the information service system receives asynchronous control request 1, control request 2, and control request 3 in sequence, there is no timing control, and these asynchronous control requests are directly sent to the control service system. And after receiving the control request 1, the control request 2 and the control request 3, the control service system respectively executes corresponding request actions, and after finishing executing the action of which control request, the control service system feeds back a corresponding control result to the information service system. For example, after the action of the control request 1 is executed, the corresponding control result 1 is returned to the information service system; after the action of the control request 3 is executed, the corresponding control result 3 is returned to the information service system; and finally, after the action of the control request 2 is executed, returning the corresponding control result 2 to the information service system.
The synchronous communication specifically includes: if the control request received by the information service system belongs to the synchronous control request, a synchronous communication method is adopted, the synchronous control request is put into the corresponding synchronous control request queue, and the synchronous control request in each synchronous control request queue is sent to the control service system according to the time sequence (namely, first-in first-out).
In a preferred embodiment of the present invention, as shown in fig. 2, the synchronization control request is divided into different synchronization control request queues according to the division of the service type of the synchronization control request, so that the request real-time performance can be improved, and the system performance can be improved. The synchronous control commands of the same synchronous control request queue have a logical relation, and the next synchronous control command queue is executed only after the execution result of the previous synchronous control request queue.
For example, suppose there are two terminals, terminal a and terminal B, and each terminal has 1, 2, 3, and 4 operations that need synchronization respectively according to the difference of the service types, that is, it must wait for the result of operation 1 to come back synchronously before 2 operations can be executed. A synchronization request queue a is set for the synchronization operation of terminal a and a synchronization request queue B is set for the synchronization operation of terminal B. There is no logic in time sequence between terminal a and terminal B, so there is no need to make the response time of the control request in terminal a influence the control request of terminal B, so terminal a and terminal B set up corresponding synchronization request queues respectively.
After receiving a synchronous control request of a terminal A, the information service system puts the synchronous control request into a synchronous request queue A corresponding to the terminal A; and after receiving the synchronous control request of the terminal B, putting the synchronous control request into a synchronous request queue B corresponding to the terminal B. And synchronously sending the synchronous control requests in each synchronous request queue according to the timing requirement, as shown in fig. 2.
Through the technical scheme, the invention has the following beneficial effects:
1) the bidirectional communication between the information service system and the control service system can be realized through the WebSocket.
2) The WebSocket channel meets two requirements of synchronous and asynchronous communication by setting a synchronous control request queue.
3) Multiple synchronization request queues may be provided, reducing the proportion of commands that must be synchronized in the system.
4) WebSocket is an application layer protocol, is easy to use, is a lightweight communication protocol, and occupies fewer resources for communication.
In addition, functional modules in the embodiments of the present invention may be integrated into one processing unit, or each module may exist alone physically, or two or more modules are integrated into one unit. The integrated unit can be realized in a form of hardware, and can also be realized in a form of a software functional unit. The functional modules of the embodiments may be located in one terminal or network node, or may be distributed over a plurality of terminals or network nodes.
In addition, each of the embodiments of the present invention can be realized by a data processing program executed by a data processing apparatus such as a computer. It is clear that the data processing program constitutes the invention. Further, the data processing program, which is generally stored in one storage medium, is executed by directly reading the program out of the storage medium or by installing or copying the program into a storage device (such as a hard disk and/or a memory) of the data processing device. Such a storage medium therefore also constitutes the present invention. The storage medium may use any type of recording means, such as a paper storage medium (e.g., paper tape, etc.), a magnetic storage medium (e.g., a flexible disk, a hard disk, a flash memory, etc.), an optical storage medium (e.g., a CD-ROM, etc.), a magneto-optical storage medium (e.g., an MO, etc.), and the like.
The invention therefore also discloses a storage medium in which a data processing program is stored which is designed to carry out any one of the embodiments of the method according to the invention described above.
