Step 408, local side access device receive that the internet-of-things terminal Long-distance Control withdraws from the platform instruction, produce the Long-distance Control claim frame that withdraws from platform, send the Long-distance Control claim frame that withdraws from platform to internet-of-things terminal;
Step 409, internet-of-things terminal are received the Long-distance Control claim frame that withdraws from platform, withdraw from and being connected of platform; Simultaneously, alternatively, disconnection is connected with network;
Step 410, internet-of-things terminal are sent the Long-distance Control acknowledgement frame that withdraws from platform to the local side access device;
Step 411, local side access device are received the Long-distance Control acknowledgement frame that withdraws from platform, report execution result to the network management module of remote control table.
Owing to be fixed with the characteristics such as high stable and high reliability that spider lines has high bandwidth, transfer of data; Increasing internet-of-things terminal is linked into network through wired mode, like the IP video camera of the various warning devices in the Smart Home and control final controlling element, video monitoring system etc.At present telecommunications network common several kinds fixedly access way PON circuit access way, DSL circuit access way, Ethernet access way, WLAN wireless access way etc. are arranged, the exemplary plot that internet-of-things terminal passes through these mode access networks respectively like Fig. 5,6,7, shown in 8.
In Fig. 5, internet-of-things terminal 51 is built-in PPPOE or DHCP dialer software, dial-up access or break off the Long-distance Control that network receives Internet of Things operation management platform 56 or sector application system 55.Internet-of-things terminal is through the multiport ONU equipment 53 of Ethernet 1 connection user side, and ONU 53 is connected to local side access device EPON OLT 52 through PON circuit 2, and OLT 52 converges to broad access network gate 54 like BRAS or SR through two layers of broadband access network.Internet-of-things terminal 51 is set up PPPOE or IPOE session connection, access network through PPPOE or DHCP dialing with broad access network gate 54.Internet of Things operation management platform 56 connects broad access network gate 54 and sector application system 55 through IP network; Realize and the communicating by letter of internet-of-things terminal 51 that through the interface protocol of agreement completion is to functions such as the configuration management of internet-of-things terminal 51, telecommunication management, Monitoring and Controlling.In addition, the also integrated termination of playing a game of platform is gone into equipment OLT 52 network operating administration modules, realizes the Long-distance Control to the terminal through local side access device OLT.Internet-of-things terminal can directly be accepted the Long-distance Control of Internet of Things operation management platform, also can accept sector application system call Internet of Things operation management platform indirectly and carry out Long-distance Control.
When Internet of Things operation management platform or sector application system can inquiry terminal configuration information, the running status situation of understanding the terminal, receiving terminal image data or when the terminal issued control command, need the remote control terminal access network.The termination of playing a game that Internet of Things operation management platform is integrated is gone into the network management module of equipment, issues control command through network management module to OLT, can realize specifying the Long-distance Control dial-up access network of internet-of-things terminal.
For realizing the Long-distance Control of local side access device to internet-of-things terminal, local side access device OLT supports remote control protocol of the present invention, specifically comprises: 1) the Long-distance Control claim frame of internet-of-things terminal access network; 2) internet-of-things terminal breaks off the Long-distance Control claim frame of network; 3) the Long-distance Control claim frame of internet-of-things terminal login platform; 4) internet-of-things terminal withdraws from the Long-distance Control claim frame of platform.When receive from webmaster internet-of-things terminal is implemented remote control commands the time, OLT can produce and to terminal transmission respective remote control request frame.In addition; OLT also need open the MAC address learning function; So that can correctly learn the MAC Address of internet-of-things terminal, find the MAC Address of specifying internet-of-things terminal in the mapping table of OLT according to MAC Address and port and send the Long-distance Control claim frame to corresponding port.
For accepting the Long-distance Control of Internet of Things operation management platform; Internet-of-things terminal is supported remote control protocol of the present invention; Specifically comprise: when the Long-distance Control claim frame that receives from local side, can discern corresponding claim frame medium-long range control messages classification, dial-up access or break off network; Login or withdraw from platform is and to local side access device return response frame.
In Fig. 5,, need to support bridge function because multiport ONU serves as the CPE of user side.When the Long-distance Control claim frame that receives from local side OLT, can correctly be forwarded to the internet-of-things terminal of appointment from corresponding ports; When the Long-distance Control acknowledgement frame that receives from internet-of-things terminal, can correctly be forwarded on the pairing local side OLT.
Provide idiographic flow below by Internet of Things operation management platform Long-distance Control internet-of-things terminal dial-up access network.
(1) Internet of Things operation management platform sends the instruction of the internet-of-things terminal access network of certain appointment of Long-distance Control to local side access device OLT through network management module.Internet of Things operation management platform stores the sign of this internet-of-things terminal and the corresponding relation of MAC Address.
(2) local side OLT receives the remote control commands of network management module; Produce the Long-distance Control claim frame; In the frame format; Dest addr address field is: specify the MAC Address of internet-of-things terminal, the message coding classification of Code field is: the dial-up access network connects (0x01), and the PDU field is inserted access network request TLV.OLT searches the pairing port of MAC Address of specifying internet-of-things terminal in mac address table, send the OAM claim frame to this port.
When (3) multiport ONU receives the Long-distance Control claim frame from OLT, in mac address table, search the pairing port of MAC Address of specifying internet-of-things terminal, transmit claim frame to this port.
(4) specify internet-of-things terminal to receive Long-distance Control claim frame from OLT; This Long-distance Control claim frame is resolved to " dial-up access network "; Promptly begin to set up session connection, obtain the IP address, subsequently to local side OLT return response frame through PPPOE or DHCP dial mode and broad access network gate.In the frame format, Dest addr address field is: the source MAC of Long-distance Control claim frame, promptly send the OLT port address of claim frame, and the message coding classification of Code field is: the dial-up access network connects (0x01), and the PDU field is inserted access network and replied TLV.
(5) OLT receives from the acknowledgement frame of specifying internet-of-things terminal, reports execution result to the network management module of Internet of Things operation management platform.
(6) internet-of-things terminal interface protocol according to a preconcerted arrangement begins to upload image data to remote control table, or the associative operations such as control of receiving remote controlling platform.
