Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in the accompanying drawing, yet should be appreciated that and to realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order to understand the disclosure more thoroughly that these embodiment are provided, and can with the scope of the present disclosure complete convey to those skilled in the art.
With reference to Fig. 2, show the schematic flow sheet of a kind of internet-of-things terminal cut-in method embodiment 1 provided by the invention, the method for present embodiment may further comprise the steps:
Step 201 is resolved the upstream message that receives self terminal, encapsulation distribution control information in described upstream message.
Wherein, the message protocol type of described upstream message comprise China Mobile's radio equipment to machine agreement WMMP, CHINAUNICOM's radio equipment to machine agreement UMMP and other custom protocol.
IAD starts the upstream message that the different monitor process such as TCP, UDP, SMS is monitored internet-of-things terminal.After listening to Internet of Things perception terminal connection request, to create a SOCKET, and give new thread and terminal communicates, the upstream message of this thread receiving terminal, and message header resolved, identify this message and belong to any agreement in WMMP, UMMP or the custom protocol.
Particularly, can adopt different IADs for different access waies.Owing to will support the plurality of access modes such as TCP, UDP, SMS, these communication modes there are differences in the realization aspect, be that TCP connects the SOCKET monitoring that will set up the TCP pattern, connection will be set up UDP Mode S OKCET monitoring for UDP, therefore adopted different IADs for different connected modes, receiving TCP such as the TCP IAD connects, the UDP IAD receives UDP and connects, can set up SOCKET with Short Message Service Gateway for the access of SMS is connected, both can adopt TCP, also can adopt UDP, in actual applications, should be connected to the master with TCP.IAD adopts the multi-process pattern, after IAD listens to request, will create a new thread, upstream message is resolved and processing related service logic by this thread, and the main thread of IAD only is responsible for monitoring.So, realized concurrent access by above-mentioned multithreading.
Owing to may carry the multiple application layer protocols such as WMMP, UMMP, custom protocol on TCP, UDP, SMS, this just need to after each connection is set up, judge which kind of application layer protocol TCP, UDP, SMS specifically carry.
IAD creates the application layer protocol of new processing threads identification upstream message. because the heading of different agreement message is fixed, therefore we can identify by heading the protocol type of message, particularly: IAD is configured the heading of the different agreement that can carry in advance, then, after receiving upstream message again, identify the form of this message protocol by the heading of resolving upstream message, comprise protocol type, protocol version etc.
The below is take the form of IAD configuration WMMP heading as example:
After receiving message, message identification thread can carry out the parsing of heading to the message data that receives, if resolve correctly, so just illustrates that this message data is the type of message that IAD can be identified.After being parsed, the raw information of the information such as protocol type, protocol version as distribution control information and upstream message is encapsulated.
Step 202 is sent to corresponding target protocol resolver according to the distribution control information with upstream message.
Protocol type and protocol version according to upstream message are selected corresponding target protocol resolver.
Preferably, upstream message is packaged into the first message with consolidation form, this first message has shielded the difference between the different information formats in this message raw information for subsequent treatment.

Message is made of message header and message body; Particularly message body is comprised of standing part and variable part, and standing part is used for storing general information, and variable part adopts label value that (Tag LengthValue, TLV) formed.
Message structure:
The message body structure:
The TLV structure:
The fixterm structure:
So whatsoever agreement can become Information encapsulation the TLV form.In use, as long as just can obtain concrete TLV value by TLVID or TLVNAME, realize to the various protocols format conversion being the internal unity form.
The second message can adopt the employed message structure body of the first message to carry, and the second message institute content mainly is service processing result information.
Which kind of protocol type is the upstream message no matter IAD receives belong to, and is the first message with unified internal form after the protocol resolver encapsulation.Operational processor can be ignored different information format between itself raw information fully when processing the first message, but processes according to unified mode, has therefore simplified business procession, has reduced logical complexity.
According to format informations such as the protocol type of message and protocol versions the second message is encapsulated as the discernible downstream message of terminal.
Step 206 sends to terminal with described downstream message.
It is the preferred method of the present invention that above-mentioned the first message that upstream message is packaged into the internal unity form is processed, based on the effective identification to the upstream message protocol format, in another preferred embodiment of the present invention, described the first message can need not to be packaged into the message with internal unity form, but the dissimilar and version according to message protocol arranges corresponding treatment mechanism in service-processing engine, has finished parsing and processing to different types of messages.
By the enforcement of above method, access when can realize simultaneously to various protocols message such as WMMP, UMMP, the application scenarios that satisfies various protocols and deposit has been eliminated the communication barrier between different agreement terminal, platform, can greatly promote the development of current Internet of Things.In addition, by implementing the present invention, can make access platform possess good extensibility, when new agreement access was arranged, the heading configuration that only needs to increase protocol analysis got final product, and need not to increase extra equipment and exploitation, greatly reduces the operation and maintenance cost.
With reference to Fig. 3, Fig. 3 shows the schematic flow sheet of a kind of internet-of-things terminal cut-in method embodiment 2 provided by the invention, protocol analysis and Business Processing are implemented by disposing protocol resolver group and operational processor group in the present embodiment, and the method for present embodiment may further comprise the steps:
The SOCKET that step 301, IAD create SMS, TCP or UDP monitors.
After step 302, IAD receive the upstream message of terminal, start new thread, by this thread the heading of upstream message is resolved.
Step 303 is attached to the distribution control information and generates new message on the raw information of message and be transmitted to the distribution controller.
