Example Embodiment

[0037] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0038] The basic idea of ​​the present invention is to classify the service flows received from the user side on the ONT, mark the control messages and data messages with different GEM Port-IDs for transmission separately, and control the control messages during transmission. The message is processed with high priority.

[0039] Wherein, the high-priority processing on the control message in the transmission process can be either high-priority processing on the control message on the ONT, or high-priority processing on the control message on the OLT. Or, it can also perform high-priority processing on the control message on the ONT and the OLT at the same time.

[0040] As shown in Figure 6, after the ONT receives the service flow from the user side, it ...

Abstract

The invention discloses a transmitting method of upward control report in the Jupiter passive optical network system, which is characterized by the following: the optical network terminal (ONT) transmits the business flow of the user to the optical line terminal (OLT), which classifies the business flow on the ONT; the control report and data report is punched by GEM Port-Ids to be transported separately, which have high precedence of the control report to process in the transmitting course. The invention makes the control report transported timely, which ensures the service quality of control report.

Description

technical field [0001] The present invention relates to optical access technology, in particular to a method for transmitting uplink control messages in a Giga-bit Passive Optical Network (GPON) system. Background technique [0002] Current broadband access technologies are mainly divided into copper wire access technologies and optical access technologies, wherein an access network implemented by the optical access technology is called an Optical Access Network (OAN). An implementation technology of an optical access network is a passive optical network (Passive Optical Network, PON) technology, which is an optical access technology for point-to-multipoint transmission. [0003] Referring to the PON system structure shown in FIG. 1 , the PON system mainly includes three parts: an Optical Line Terminator (OLT), an Optical Distribution Network (ODN) and an Optical Network Unit (ONU). Among them, the OLT is used to provide the network side interface (SNI) for the OAN, and con...
