一种参数粒度的传递方法和装置
摘要：
本发明公开了一种参数粒度的传递方法和装置，包括：光线路终端(OLT)通过测距带宽(Ranging GRANT)消息将参数粒度传递给光网络单元(ONU)；或者，通过配置物理层操作管理和维护(Profile PLOAM)消息将参数粒度传递给ONU；或者，通过光网络终端管理控制接口(OMCI)的设置(SET)操作将参数粒度设置给ONU；ONU根据参数粒度以及参数粒度在分配结构中对应的参数确定OLT分配给自身的上行带宽在上行帧中的位置。通过本发明，可以在OLT为不同ONU分配上行带宽时，将采用的参数的粒度通知ONU。
摘要（英）：

A method and a device for transmitting parameter granularity are disclosed. The method includes: an Optical Line Terminal (OLT) transmits parameter granularity to an Optical Network Unit (ONU) through a Ranging GRANT message, or an OLT transmits parameter granularity to an ONU through a profile Physical Layer Operation, Administration and Maintenance (PLOAM) message, or parameter granularity is set to an ONU through a SET operation of an Optical Network Terminal Management Control Interface (OMCI); and the ONU determines a location of an uplink bandwidth allocated from the OLT to the ONU in an uplink frame according to the parameter granularity and a parameter to which the parameter granularity corresponds in an allocation structure. With the disclosure, the granularity of an adopted parameter can be notified to different ONUs when the OLT allocates an uplink bandwidth to the different ONUs.
