Fig. 3 is the flow chart of the method for another reduction consumption of passive optical network line of the embodiment of the invention.
The operating state of step 31, ONU active detecting local service treatment system knows that transaction processing system is in free time (IDLE) state.
After step 34, OLT issued the instruction that enters low power consumpting state to ONU, it was the OLT-IDV5 state that the ONU particular state machine of OLT enters low power consumpting state (ONU low power states); After ONU received the low power consumpting state instruction of OLT, the ONU state switched to low power consumpting state, is defined as the O8 state here.
Under the OLT-IDV5 state, the operation of OLT can comprise:
Pressing the time of timer TO3 setting distributes PLOAM or the minimum bandwidth (min BW) of setting, LOS/LOF (i) and the upstream data of detection ONU (i) regularly for ONU (i).If ONU (i) is in LOS (i)/LOF (i) state, then be left intact; If regularly all detect LOS (i)/LOF (i) m time continuously, show that then irrecoverable error has appearred in ONU (i), then OLT returns initial condition.
OLT has on the data and gives the correct time when detecting ONU (i), and the minimum bandwidth of setting of continuous dispensing n frame is given ONU (i), and ONU is after OLT distributes bandwidth, and the data of up transmission proprietary protocol are to OLT.OLT confirms the data that ONU reports.Check simultaneously ONU (i) on call time, determine whether need to adjust its equivalence time-delay (Equalization Delay, EQD).OLT is to the data validation of continuous n frame, if data show that ONU initiatively requires to withdraw from low power consumpting state, illustrate that ONU detects particular event and need withdraw from low power consumpting state, then OLT sends order request ONU (i) to switch to Operation States is the OLT-IDV3 state; Otherwise keep current state constant.
If OLT receives the anomalous event of ONU (i), incidents such as PLOAM message that reports such as SN or rogue ONU testing result, show that the O3 state self has taken place to enter unusually ONU (i), then OLT can withdraw from this state, and entering Initial State is the OLT-IDV1 state.
OLT continues to send the information that its up-stream system sends to ONU according to the descending timing of ONU (i), guarantees that ONU (i) receives this information, can select to remain on low power consumpting state when ONU receives these information or selection is withdrawed from.
Before ONU enters the O8 state, the ONU of this ONU can be identified information stores such as (ONU ID), EQD, network configuration in nonvolatile storage, close up-downgoing optical module power supply, close GPON SerDes, close the clock of GPON MAC, reduce the processing clock of CPU, make system enter holding state, also promptly enter the O8 state.After ONU enters the O8 state, can detect particular event (detecting the phone off-hook), network side by this locality and detect the multiple mode waken systems such as control command that OLT is received in particular event (such as the VOIP signaling message of having received that local side sends), network side, promptly withdraw from the O8 state such as SLIC.
Under the O8 state, the operation of ONU can comprise:
Regularly open by the setting of timer TO4 and to receive path such as optical module is descending, SerDes is descending and GPON MAC is descending.The time that the duration that downlink is opened is at every turn set for timer TO5.The time that time=n that timer TO5 sets * timer TO4 sets, n=1,2..., and the value of n must guarantee the time of time＞=2 * timer TO3 setting that timer TO5 sets.Whether after the data sync of realization and local side, detecting has the data that send to this ONU, and detects data content according to predefined strategy, determines whether to wake whole system up.
ONU by the setting of timer TO5 regularly open transmission path such as the up power supply of optical module, SerDes is up and GPON MAC is up etc.The time that time=n that TO5 sets * timer TO4 sets, n=1,2..., wherein, n=1 represents that sendaisle and receive path open simultaneously, only, this moment, sendaisle was just for open mode, and do not start working as yet, just started working after having only down-going synchronous to finish.Descending finish data sync after, refresh ONU ID, EQD and GEMPORT configuration, detect downlink bandwidth after, ONU sends predefined data according to configuration to OLT on up direction, and carry out subsequent operation according to the indication of OLT.Predefined data can be by transmissions such as privately owned PLOAM agreement, particular data newspaper, format.The duration that sendaisle is opened can be set as required, can be 1 millisecond, 3 milliseconds etc., but must equal the twice of the time that TO3 sets at least.
This locality detects in the particular event and has no progeny, cpu system among the ONU at first starts, open the optical module power supply, open GPON SerDes, open GPON MAC, after finishing configuration restore, send the message that request breaks away from low power consumpting state to OLT, after the agreement of OLT feedback, switch to Operation States (O5);
Descending control command (the data structure of PLOAM message or other agreements that receives the OLT transmission of ONU, such as deexcitation ONU (Deactive ONU) message) time, initiatively triggering CPU restarts, ONU carries out state according to the control command of OLT and switches (same with other scenes, then get back to the O3 state such as receiving deexcitation ONU message), do not need to be configured the operation of recovery.
ONU is descending when receiving specific data-message (such as the VOIP signaling message), cpu system at first starts, open the optical module power supply, open GPON SerDes, open GPON MAC, after finishing configuration restore, send the message that request breaks away from low power consumpting state to OLT, after the agreement of OLT feedback, switching to running status (Operation States) is the O5 state.
Below with the PLOAM private message as the main media of realizing the low-power consumption information interaction, the handling process of integral body be described, also can use frame data structure, OMCI message and other private data pass through mechanism to realize.

Under the OLT-IDV5 state, the operation of OLT can comprise:
OLT distributes PLOAM or the minimum bandwidth (min_BW) of setting regularly for ONU (i) according to the setting-up time of timer TO3, detects LOS/LOF (i) and the upstream data of ONU (i).If ONU is in LOS (i)/LOF (i) state, then be left intact; If regularly all detect LOS (i)/LOF (i) m time continuously, show that then irrecoverable error has appearred in ONU (i), then OLT returns initial condition.
Detecting ONU (i) has under the situation that data report, and the minimum bandwidth of setting of OLT continuous dispensing n frame is given ONU (i), and reported data is confirmed.Check simultaneously ONU (i) on call time, determine whether need to adjust its EQD.The data validation of n frame if show that ONU initiatively requires to break away from low power consumpting state, then sends order continuously, requires ONU (i) to switch to running status (OLT-IDV3); Otherwise, keep current state constant.
If receive the anomalous event of ONU (i), incident such as the PLOAM message that reports such as SN or rogue ONU testing result shows that the O3 state self has taken place to enter unusually ONU (i), and then OLT withdraws from this state, enters initial condition (OLT-IDV1).
OLT does not discern and detects the information that sends to ONU (i), directly handles getting final product according to original strategy, has reduced the processing burden of OLT.
The operation of ONU under the O8 state can comprise:
Before ONU enters the O8 state, with information stores such as ONU ID, the EQD of this ONU, network configuration in nonvolatile storage, close up optical module power supply, close the uplink module clock that GPON SerDes is up, close GPON MAC, reduce the processing clock of CPU, make system enter holding state.Waken system can detect that particular event (detecting the phone off-hook such as SLIC), network side detect particular event (such as the VOIP signaling message of having received that local side sends), network side receives that the multiple modes such as control command of OLT realize by this locality.
Keep the downlink normally open, keep synchronously with OLT all the time, whether detection in real time has the data that send to this ONU, and detects data content according to predefined strategy, determines whether to wake whole system up.
ONU by the setting of timer TO5 regularly open transmission path (the up power supply of optical module, SerDes is up and GPON MAC up), the time that time=n that timer TO5 sets * timer TO4 sets, n=1,2....Descending finish data sync after, refresh ONU ID, EQD and GEMPORT configuration, detect downlink bandwidth after, up direction sends predefined data according to configuration to OLT, and carries out subsequent operation according to the indication of OLT.Predefined data can be by transmissions such as privately owned PLOAM agreement, particular data newspaper, format.
This locality detects in the particular event and has no progeny, and cpu system at first starts, and opens the optical module power supply, opens GPON SerDes, opens GPON MAC, after finishing configuration restore, send the message that low power consumpting state is withdrawed from request to OLT, after confirming through OLT, switch to the O5 state;
Descending control command (the data structure of PLOAM message or other agreements that receives the OLT transmission of ONU, such as deexcitation ONU message) time, initiatively triggering CPU restarts, ONU carries out state according to the control command of OLT and switches (same with other scenes, then get back to the O3 state such as receiving deexcitation ONU message), do not need to be configured the operation of recovery.
ONU is descending when receiving specific data-message (such as the VOIP signaling message), cpu system at first starts, open the optical module power supply, open GPON SerDes, open GPON MAC, after finishing configuration restore, send the message that low power consumpting state is withdrawed from request to OLT, after the OLT affirmation, switch to the O5 state.
In the present embodiment, ONU often opens by keep descending GPON passage under low power consumpting state, has guaranteed that further ONU still can guarantee the unimpeded of lifeline under low power consumpting state.
