Description
Technical field
The present invention relates to a kind of PON system and state updating method thereof.
Background technology
PON(Passive Optical Network: passive optical-fiber network), PON system is primarily of the OLT(Optical Line Terminal of console for centralized control: optical line terminal), comprise the ODN(Optical Distribution Network of Passive Optical Components: optical distribution network) and the ONU(OpticalNetwork Unit of user side: optical network unit) composition.
The state information of ONU is by MPCP(Multi-Point Control Protocol: Multi-point Control Protocol) information reporting is to the sub-card system in OLT, the status information transmission of ONU, after receiving the reporting information of ONU, is upgraded local show state to OLT user side equipment (OLT main control unit) OLT user side equipment according to the state information obtained by OLT sub-card system.The defect of this method is: roll off the production line on ONU in enormous quantities is frequent the channel block made between OLT sub-card system and OLT user side equipment, OLT intercommunication pressure is huge, the linking status of ONU and OLT cannot be obtained in OLT user side equipment is long-time, other function of OLT also can be caused simultaneously normally to use.
In prior art, a sub-card system comprises multiple PON mouth, the multiple ONU of corresponding connection under a PON mouth, the change of the linking status of ONU and sub-card system is that ONU is initiatively sent to sub-card system by MPCP message, as long as there is the linking status of an ONU and sub-card system to change, the state of the ONU of change can be sent to user side equipment by sub-card system.Once the linking status between ONU and sub-card system changes frequently, sub-card system will ceaselessly report the state information of ONU to OLT user side equipment continually, can cause sub-card system and user side equipment channel block like this.Sub-card system and user side equipment channel block will cause user side equipment cannot obtain the linking status of ONU and sub-card system for a long time, if when at this moment having webmaster terminal request to obtain the connection status of ONU, user side equipment cannot provide the state confession webmaster terminal demonstration of correct ONU, and channel block also can cause other functions of OLT or business normally not to run.
And in the present invention, consider 1 ONU frequent on roll off the production line not representative for whole large-scale PON system, described sub-card system receive state information that ONU sent by MPCP (as ONU reach the standard grade, ONU rolls off the production line) after, not send to user side equipment at once, but the frequency of all ONU changes under judging this PON mouth that ONU connects, such as, under PON mouth connection 5 ONU, these 5 ONU all roll off the production line within a period of time, and so sub-card system just can obtain the frequency of the state variation of the whole ONU corresponding to described PON mouth.
Then, described frequency and first threshold are compared (first threshold can artificially be arranged), if frequency is higher than described first threshold, described sub-card system is immediately by the state transfer of the whole ONU under PON mouth now, report user side equipment, the time reported is adjusted like this according to described frequency, can ensure that between sub-card system and user side equipment, channel does not block, the state of ONU can report accurately, not only user side equipment can obtain the state of correct ONU but also the communication pressure reduction of OLT inside, other function of PON system or business can be operated normally.
