| 2 | MAC | The user terminal MAC Address of certification |
| x | Portal web | The network address of portal certification |
Step S206, ONU transmit the access authentication page according to user terminal MAC Address to user terminal;
Particularly, the access authentication page according to user terminal MAC Address, and is passed to user terminal by http protocol after receiving the access authentication page of OLT propelling movement by ONU, after user terminal receives the access authentication page, carry out access authentication at this access authentication page.
Step S207, OLT are to ONU informing user terminal authentication result;
Particularly, the authentication result of OLT recording user terminal on the access authentication page, and by OAM agreement, user terminal is informed to ONU in the authentication result of the access page;
Step S208, ONU confirm whether user end certification result is passed through, when authentication result be by time, proceed to step S210, when authentication result be do not pass through time, enter step S209;
Particularly, OLT is by the authentication result of OAM notice of settlement ONU user terminal, if certification is passed through, then ONU lets pass to this user terminal, thus user terminal can be surfed the Net, if certification is not passed through, then enters step S209;
Step S209, ONU do not allow user terminal to surf the Net, and continue certification after waiting for Preset Time;
Particularly, for the user terminal that certification is not passed through, ONU does not allow online, after can waiting for the certain predetermined time, enters step S201, and user terminal proposes user terminal online request, request online; Wherein, ONU arranges Preset Time can be 30s, 60s etc.
Step S210, allows user terminal online.
Particularly, ONU can preserve authentication result, during user terminal proposition next time online request, not need to carry out certification again.
Fig. 3 shows Ethernet passive optical network connecting system example structure schematic diagram provided by the invention.As shown in Figure 3, this system comprises: OLT301, ONU302 and UE303.
OLT301 pushes the access authentication page to ONU302, and sends the authentication result of user terminal to ONU302 after asking for the user terminal online receiving ONU303 transmission.
ONU302 is used for OLT301 report of user terminal online request, for UE303 transmits the access authentication page, determines whether to allow UE303 online, preserve certified user terminal simultaneously according to the authentication result that OLT301 sends.
UE303 is used for sending user terminal online request to ONU302, and the access authentication page receiving ONU302 transmission carries out certification.
Wherein, OLT301 and ONU302 is undertaken alternately by OAM agreement, and OAM agreement is the interactive interface of OLT301 and ONU302; ONU302 and UE303 is undertaken alternately by http protocol, and http protocol is the interactive interface between ONU302 and UE303.
The concrete of OLT301, ONU302 and UE303 is alternately: the user terminal of acquisition online request and user terminal MAC Address are sent to OLT301 by OAM agreement by ONU302; OLT301 receive user terminal online request after, by OAM agreement by access authentication page push to ONU302; The access authentication page according to user terminal MAC Address, and is passed to UE303 by http protocol after receiving the access authentication page of OLT301 propelling movement by ONU302; After UE303 receives the access authentication page, carry out access authentication at this access authentication page; OLT301 records the authentication result of UE303 on the access authentication page, and according to the user terminal MAC Address received, UE303 is informed to ONU302 in the authentication result of the access page; ONU302 confirms whether the authentication result of UE303 is passed through, when confirm authentication result be by time, ONU302 lets pass to UE303, thus UE303 can surf the Net, when confirmation certification is obstructed out-of-date, ONU302 does not allow UE303 to surf the Net, and continues certification after waiting for Preset Time.
Wherein, the user terminal of acquisition online request and user terminal MAC Address are sent to OLT301 by ONU302, specifically comprise: ONU302 judges that whether UE303 is authenticated after getting user terminal online request, if authenticated, then allow UE303 online; If there is no certification, then the user terminal of acquisition online request and user terminal MAC Address are sent to OLT301.
Wherein, the user terminal of acquisition online request and user terminal MAC Address are sent to OLT301 by the report and alarm message of OAM agreement by ONU302, and wherein, the report and alarm message format of OAM agreement is as shown in the table:
Wherein, OLT301 by OAM agreement issue access message by access authentication page push to ONU302, wherein, OAM agreement issue access message format as shown in the table:
