The second terminal in M2M system comprises: higher level's terminal selects module, registration request sending module and message receiver module.
Higher level's terminal selects module, for selecting higher level's terminal in the father node from self.
Registration request sending module, for successively via selected higher level's terminal and first terminal, sends registration request to M2M platform, carries the parent information of the second terminal in registration request.

Higher level's terminal select module can be preset according to this locality higher level's terminal alternative condition, from the father node that this locality is preset, select higher level's terminal of the second terminal.
Higher level's terminal selects module also can send request message to M2M platform, acquisition request network configuration; And the father node of the second terminal returned according to M2M platform and the topological structure relevant with its father node to the second terminal, according to local preset higher level's terminal alternative condition, from the father node of the second terminal, select higher level's terminal.
The communication means of the M2M system that M2M system as shown in Figure 1 realizes, as shown in Figure 2, mainly comprises the following steps:
Step 201, the second terminal selects higher level's terminal from the father node of self, and successively via selected higher level's terminal and first terminal, sends registration request, carry the parent information of the second terminal in registration request to M2M platform.
When installation the second terminal, can in the second terminal the father node of preset higher level's terminal alternative condition (as according to conditions such as bandwidth, alarm number of times, terminal models, application and/or the network segments) and this second terminal, higher level's terminal alternative condition that so the second terminal can be preset according to this locality, selects the higher level's terminal of self from the father node that this locality is preset; Or,
When installation the second terminal, also can not in the second terminal the father node of this second terminal preset, so the second terminal can select higher level's terminal by following approach from the father node of self: the second terminal sends request message directly to M2M platform, acquisition request network configuration; M2M platform returns the father node of the second terminal and the topological structure relevant with its father node to the second terminal to the second terminal according to the address information (as IP) of the second terminal to report; Second terminal is according to the topological structure obtained, and local preset higher level's terminal alternative condition (as according to conditions such as bandwidth, alarm number of times, terminal models, application and/or the network segments), from the father node of the second terminal, select the higher level's terminal of self.Preferably, M2M platform is after receiving the request message from first terminal, legitimacy verification can be carried out to first terminal, verification rule can according to related protocol, as M2M device management protocol (MDMP, M2M Device Management Protocol) etc., what namely verify described first terminal is identified in M2M platform whether have typing, then verify if any typing and pass through, and in verification by rear execution subsequent operation.
Preferably, can also carry in the registration request of the second terminal and report routing iinformation, report routing iinformation comprise registration request by way of terminal iidentification, and report the terminal iidentification in routing iinformation be according to registration request by way of terminal order arrangement.
If namely the higher level's terminal selected by the second terminal is the first terminal direct-connected with M2M platform, so the registration request of the second terminal is sent to M2M platform after selected first terminal.Described second terminal sends to and reports in routing iinformation the mark comprising described second terminal entrained by the registration request of first terminal; Described first terminal sends to and reports in routing iinformation the mark comprising described first terminal and the second terminal entrained by the registration request of M2M platform, and the mark of described first terminal adds after the mark of the second terminal.
If the higher level's terminal selected by the second terminal is not the first terminal direct-connected with M2M platform, so registration request is first sent to selected higher level's terminal by the second terminal; After described higher level's terminal receives registration request, according to destination address, after generating route (current route comprises described second terminal and this higher level terminal, and this higher level terminal adds after the second terminal), be sent to the higher level's terminal of oneself.The rest may be inferred, until this registration request is sent to the first terminal of direct-connected M2M platform.In the registration request that M2M platform receives, what it carried reports routing iinformation to comprise: higher level's terminal ... of described second terminal, the second terminal, the first terminal of described direct-connected M2M platform, and these information add successively according to the order of registration request by way of terminal.When described second terminal is after M2M platform succeeds in registration, M2M platform will record the above-mentioned database of parent information to self reporting routing iinformation and the second terminal.
Step 202, M2M platform performs the registration to the second terminal, record the parent information of the second terminal, and according to the parent information of the second terminal and the platform route of corresponding second terminal of preset route generation strategy generation, issue data message according to platform route to first terminal.
After M2M platform performs the registration to the second terminal, no matter that M2M platform is when responding the data message of the second terminal, or when M2M platform is initiatively initiated to the data message of the second terminal, M2M platform all needs the platform route generating corresponding second terminal according to preset route generation strategy, and issues data message according to platform route to direct-connected first terminal.
If carry in the registration request of the second terminal and report routing iinformation, so M2M platform can according to the parent information of the second terminal, the platform route reporting routing iinformation and corresponding second terminal of preset route generation strategy generation.
Wherein, preset route generation strategy can adopt following one of them:
According to selected attribute (alarm, bandwidth etc.) and weights thereof, according to global optimum's strategy generating platform route;
According to selected attribute, according to local optimum strategy generating platform route;
Report routing iinformation as platform route terminal.
Below to choose the attribute of alarm and bandwidth, the method according to global optimum's strategy generating platform route is introduced.
Account form for bandwidth weighting is as follows:
Traversal object terminal, to all paths of M2M platform, in the process of accessed path, if run into not line node (terminal), abandons this paths.The bottleneck bandwidth of minimum bandwidth as this path of the node on every paths is recorded when searching;
The bottleneck bandwidth in all paths found out and nodes are normalized:
Bottleneck bandwidth normalization NORMbi:Bi/SUM (B1, B2 ..., Bn), wherein, Bi represents the bottleneck bandwidth of path i, and SUM represents summation operation;
Nodes normalization NORMni:(1/Ni) and/SUM (1/N1,1/N2 ..., 1/Nn), wherein, Ni represents the nodes of path i, and SUM represents summation operation;
The weighted sum that scoring SCOREi, SCOREi are NORMbi and NORMni is calculated to each paths, supposes that weight is 1, namely think nodes and bottleneck bandwidth no less important:
SCOREi＝NORMni+NORMbi
In all paths found out, prioritizing selection does not have the path of alarming node; If there is multiple such path, then the path that preferably SCORE is maximum; If all there is alarming node in all paths, then the path that preferably SCORE is maximum.The path choosing out by said method is the platform route of generation.
Again the method according to local optimum strategy generating platform route is introduced below.
Local optimum refers to according to local condition's selection, as only selected the minimum alarm of higher level's terminal, or only selects higher level's terminal bandwidth maximum.
Such as: terminal A has two higher level's terminals, i.e. terminal B and terminal C; When selecting according to the principle that alarm is minimum, terminal B has 1 alarm, and terminal C has two alarms, so, terminal B should be selected as the node in path.
Again such as: terminal A has two higher level's terminals, i.e. terminal B and terminal C; When selecting according to the principle that bandwidth is maximum, the band of terminal B is wider than the bandwidth of terminal C, so, terminal B should be selected as the node in path.
So-called report routing iinformation as platform route terminal, refer to that when terminal last being arrived M2M platform, the routing iinformation of this M2M platform record is as platform route.The precondition of this mode is, terminal has at least arrived M2M platform once, and M2M platform have recorded this routing iinformation.M2M platform selecting terminal report routing iinformation as platform route carry out data message issue time, should judge that this reports each terminal in routing iinformation whether online; If all online, then show that this mode can issue; If there is terminal not online, then show that this mode can not issue, thus need to select aforesaid global optimum strategy or local optimum strategy generating platform route.
Step 203, the data message that M2M platform is mail to the second terminal by first terminal is sent to the second terminal according to platform route or according to the route that self determines.
M2M platform after the platform route generating corresponding second terminal, can arrange whether force usage platform route in the data message mailing to direct-connected first terminal;
Accordingly, described first terminal is after receiving M2M platform and mailing to the data message of the second terminal, judge that object terminal is not oneself, whether mandatory requirement is according to platform route sending-down data message then to need to judge M2M platform, if be judged as forcing usage platform route, then must to send datagram the second terminal according to platform route; If be judged as optional usage platform route, then can according to actual conditions, to send datagram the second terminal or to send datagram its next terminal according to the route that self determines, until data message arrives the second terminal according to platform route.
Embodiment shown in composition graphs 3 ~ Fig. 5 more below, further describes the communication means of M2M system of the present invention.
In the M2M system shown in Fig. 3, terminal A is the second terminal, and terminal B, terminal C are first terminal, and terminal A is installing and after powering on, according to preset higher level's terminal alternative condition, selecting terminal C as its higher level's terminal from terminal B, terminal C; Then, send registration request to terminal C, wherein carry following information: destination is M2M platform, source terminal is terminal A, father node comprises terminal B and terminal C, current route is terminal A.After terminal C receives registration request, route is generated according to destination address, and by the route generated, registration request is sent to its higher level's terminal, in the present embodiment, due to the direct-connected M2M platform of terminal C, therefore the registration request received directly is sent to M2M platform by terminal C, carries following information: destination is M2M platform, source terminal is terminal A, father node comprises terminal B and terminal C, current route is terminal A terminal C in the registration request that terminal C sends.M2M platform receives registration request, registers terminal A, and the father node recording terminal A is terminal B and terminal C and routing iinformation.
As shown in Figure 4, when M2M platform issues data message to terminal A, selected platform route is be that terminal A terminal C issues according to the route of record, and pressure is set by platform route sending-down, so M2M platform issues data message to terminal C, wherein carries following information: destination is terminal A, source is M2M platform, current route is terminal A terminal C, force to send by platform route.After terminal C receives this data message, be judged as arranging and force by platform route sending-down, and by this data message according to platform route sending-down to terminal A, the information of wherein carrying comprises: destination is terminal A, source is M2M platform, current route is terminal A (mark of terminal C is deleted from routing iinformation).
Again as shown in Figure 5, in the M2M system of Fig. 5, terminal C is the direct-connected first terminal of M2M platform, and terminal A is the second terminal, and terminal B and terminal D are the father nodes of terminal A.When M2M platform issues data message to terminal A, selected route is terminal A terminal B terminal C, and so it sends in the data message of direct-connected terminal C and carries following information: destination is terminal A, source is M2M platform, current route is terminal A terminal B terminal C, need not force to send by platform route.After terminal C receives this data message, judgement need not be forced according to platform route sending-down, then select one according to actual conditions and more excellent issue path, so the more shortest path can selected according to oneself issues this data message (no longer by the route sending-down of terminal A terminal B terminal C), its more shortest path selected is terminal A terminal D terminal C, and so terminal C sends in the data message of terminal D and carries following information: destination is terminal A, source is M2M platform, current route is terminal A terminal D (mark of terminal C is deleted from routing iinformation).Terminal D is transmitted to terminal A according to routing iinformation after receiving this data message, and the information of carrying in data message comprises: destination is terminal A, source is M2M platform, current route is terminal A (mark of terminal D is deleted from routing iinformation).
In sum, by the present invention, M2M platform can be managed to terminal implementation levelization, and the specification handles of the route selection realized in M2M system and node recognition, make the M2M system based on level can complete communication interaction in netted tree structure.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
