A kind of preferred embodiment in, described method is further comprising the steps of afterwards in step (7):
(8) described OLT judges whether existing number of channels satisfies the needs that send OMCI information, if, then get into step (9), if not, then return step (6);
(9) described OLT judges in the existing expansion OMCI passage whether have the passage that is not used, if, then get into step (10), if not, then return step (7);
(10) described OLT discharges the expansion OMCI passage that is not used.
In practical application; The present invention is in order to set up many dynamic Virtual Channels with transmission OMCI message; This method is given tacit consent to after system initialization on the basis of the special-purpose Virtual Channel of setting up a transmission OMCI message, judges that whether the OMCI message that OLT will handle is many, just sets up many channel transfer OMCI message if there are many OMCI message to handle; And give each channel number; Make OMCI message to get into each channel transfer according to channel position according to sequencing, if the OMCI message of back is on the OMCI message basis in front, then this OMCI transmission of messages with correlation is just utilized identical passage.Judge that in the process of OMCI transmission of messages can existing OMCI passage satisfy the transmission requirement of OMCI message; The OMCI message that transmits if desired is still many; Then continue to set up transmission channel,, but be no more than the maximum number that to support passage up to the transmission requirement that satisfies OMCI message.Simultaneously, in the process of transmission OMCI message, want the operating state of sense channel, if having passage in the regular hour, not to be used then discharge, but the default channel that produces system initialization the time can keep.As shown in Figure 2, the concrete steps in practical application of this method comprise:
1, the ONU initialization begins to register to OLT after powering on; When accomplishing registration, ONU gets into normal operating conditions (05Operation-state); The Virtual Channel that can set up a special use between OLT and the ONU is used for transmitting OMCI message, and OLT can come to send OMCI message to realize the configuration management to ONU to ONU through the OMCI passage.
2, system can send various OMCI message after setting up the OMCI passage; Judge the value volume and range of product of OMCI message this moment; If quantity is many or kind begins to set up many OMCI passages more at most; And the sequencing according to creating is numbered, if the channel transfer that the quantity of OMCI message was set up when only needing through system initialization at least gets final product.
3, under the prerequisite of setting up many OMCI message channels; OMCI message gets into each passage according to sequencing according to the OMCI serial number of channels; If the OMCI message of back is on the OMCI message basis in front, then this OMCI message with correlation is transmitted with regard to utilizing identical passage.
4, judge that in the process of OMCI transmission of messages can existing OMCI passage satisfy the transmission requirement of OMCI message, the OMCI message that transmits if desired is still many, then continues to set up transmission channel, up to the transmission requirement that satisfies OMCI message.
5, the operating position of monitoring OMCI passage if having passage not to be used within a certain period of time or the corresponding OMCI type of message of this passage not, just discharges this OMCI passage.
Adopted the method that realizes dynamic multichannel OMCI transmission of messages in the PON system of this invention between OLT and ONU; OLT sets up the expansion OMCI passage that is communicated with described ONU according to the species number of OMCI information; And utilize initial OMCI passage and described expansion OMCI passage to send OMCI information to ONU simultaneously; Thereby when having more OMCI message to send to ONU, come to transmit simultaneously OMCI message, thereby effectively improve the efficient of OLT the ONU configuration management through many passages through the OMCI passage; And further improve the whole work efficiency of system; And the implementation method of method that realizes dynamic multichannel OMCI transmission of messages in the PON of the present invention system between OLT and ONU is simple, realizes with low costly, and range of application is comparatively extensive.
In this specification, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
