As shown in Figure 2, mainly comprise the steps: according to the M2M application of the embodiment of the invention and the communication means of M2M terminal
S202, Internet of Things is used and is sent a request message to the Internet of Things platform;
S204, the internet-of-things terminal that the Internet of Things platform is asked to request message is authorized;
S206, Internet of Things platform use the visit information that sends internet-of-things terminal to Internet of Things;
S208, Internet of Things is used and is communicated according to visit information and internet-of-things terminal.
In the prior art, M2M uses and must just can communicate with the M2M terminal by the M2M platform, has so not only increased the weight of the load of M2M platform, and has increased the processing links of whole system, has increased system's time delay.Review the embodiment of the invention, mandate by the M2M platform, can use with the M2M terminal at M2M and set up the communication link that is used for direct communication, make M2M use and do not need to pass through again the M2M platform with M2M communication between terminals data, thereby reduced the load of M2M platform, and simplified whole system processing links, reduced system's time delay.
Preferably, the described Internet of Things platform internet-of-things terminal of being asked to described request message is authorized and can be adopted following steps: described Internet of Things platform obtains the described visit information of the internet-of-things terminal that described request message asked; Described Internet of Things platform generates authorization message according to described visit information and described request message institute requested operation information; Described Internet of Things platform sends to described internet-of-things terminal with authorization message.
Visit information can comprise the communication capacity information of internet-of-things terminal in the present embodiment, like this, the Internet of Things platform is after taking all factors into consideration visit information and institute's requested operation information, can generate corresponding authorization message, its can comprise following one of at least: the echo plex mode of content of operation, number of operations, operating time, operating result, return time of operating result or the like.Like this, can realize controlling flexibly Internet of Things is used and internet-of-things terminal between direct communication.
Preferably, after described Internet of Things platform obtained the described visit information of the internet-of-things terminal that described request message asked, the Internet of Things platform judged at described Internet of Things to use whether needs are encrypted when communicating with described internet-of-things terminal according to described visit information; If need to encrypt, then described Internet of Things platform generates key, described key is sent to described Internet of Things use and internet-of-things terminal.
By above-mentioned cipher mode, make and between M2M application and M2M terminal, can carry out coded communication, thereby increased safety of data transmission.
Preferably, described request message is carried the sign and the described operation information of the sign of described internet-of-things terminal, the application of described Internet of Things, and wherein, described operation information comprises content of operation and the number of operations of described Internet of Things application to described internet-of-things terminal.
Preferably, described Internet of Things is used to communicate according to described visit information and described internet-of-things terminal and comprised: described Internet of Things application is set up communication link according to described visit information and described internet-of-things terminal; Described Internet of Things is used to described internet-of-things terminal transmit operation request message; Described internet-of-things terminal is carried out described operation requests message institute requested operation, and uses the return result to described Internet of Things.
Preferably, when M2M use set up communication link according to the visit information of M2M terminal and M2M terminal after, M2M uses to M2M terminal transmit operation request message, and at this moment, the M2M terminal can respond operation requests message according to sign and the operation information that M2M uses.Preferably, after receiving the operation requests of using from M2M, the M2M terminal can be judged at first whether operation requests that M2M uses belongs within the scope of operation information of authorization message indication and judge whether the corresponding number of operations of sign that local that preserve and this M2M use is 0.If belong in the scope of operation information of mandate and number of operations greater than 0 time, then the M2M terminal is carried out corresponding operation, and behind EO, operating result is returned to M2M use, the M2M terminal number of operations that the sign with this M2M application of this locality preservation is corresponding subtracts 1 simultaneously.If do not belong in the scope of operation information of mandate and number of operations equals 0 time, then the M2M terminal is not carried out corresponding operation, and the directly response of return request failure.By the way, the M2M terminal can be controlled the operation of M2M application effectively.
Preferably, use after the Internet of Things platform sends a request message at Internet of Things, the sign that described Internet of Things platform is used according to the described Internet of Things that carries in the described request message judges described Internet of Things uses whether have authority; If do not have an authority, then described Internet of Things platform is used to described Internet of Things and is sent the request failure response, and the operation of authorizing of the cancellation internet-of-things terminal of being asked to described request message.
By at aforesaid way, the M2M platform can be controlled the access that M2M uses, make the illegal M2M that inserts (for example use, the not enough M2M that do not pay the fees or pay the fees uses) can not obtain the authorization so that set up the communication link that is used for direct communication with corresponding M 2M terminal, thereby increased the configuration flexibility of whole system, be convenient to of the control of M2M platform the direct communication mode.
Preferably, in the above-described embodiments, described visit information comprise following one of at least: the communication mode of described internet-of-things terminal, the function that described internet-of-things terminal is supported and the information of calling.Use by these visit informations being sent to M2M, can set up corresponding communication links according to these visit informations so that M2M uses.
Preferably, described Internet of Things use communicate according to described visit information and described internet-of-things terminal after, the M2M platform is used and authorization message is cancelled in the transmission of M2M terminal to M2M; M2M uses and the M2M terminal disconnects communication link according to the cancellation authorization message.In this way, set up the mechanism that cancellation is authorized, thereby under special screne, the M2M platform can be cancelled M2M by the way and use and M2M communication between terminals link, thereby further increased the configuration flexibility of whole system, be convenient to of the control of M2M platform the direct communication mode.
Describe the communication means do not encrypted and the communication means of encryption in detail below by accompanying drawing.
Because the M2M terminal capability that has, as: the M2M terminal capability that has is more weak, does not support the security certificate function; Also having the operation aspect to consider, may be exactly the topic construction of this application as: this equipment, does not also have special demand for security.The M2M platform might be made a strategic decision and will carry out safe coded communication when being agreed the M2M application request, also may not want coded communication, so, divide 2 flow processs to illustrate here.
Simultaneously, need to prove also that before M2M used application, M2M used and realize registration to the M2M platform earlier, relevant M2M terminal also should be finished the registration to the M2M platform.M2M uses and has got access to the visit information that needs the M2M of direct communication terminal by M2M platform or alternate manner.
