Problems solved by technology

The user requires the same ONU to support PPTP Ethernet UNI data service, VEIP data service, VoIP service and TR-069 management service at the same time, but the single equipment type of ONU cannot meet such application requirements; the same customer can simultaneously access SFU type ONU and The HGU type ONU will sharply increase the operation and maintenance cost of the optical access network
[0005] And under normal circumstances, the equipment type of the ONU factory is SFU or HGU, and the OLT (optical line terminal, optical line terminal) delivers the corresponding services according to the type of ONU equipment. However, in the intercommunication scenario, especially for international projects, each manufacturer The OLT and the ONU are connected in a mixed connection. The OLT will not issue corresponding services according to the equipment type of the ONU, but will issue services at will according to the requirements of the operator, such as delivering VEIP data services to SFUs, PPTP Ethernet UNI data services to HGUs, and SFU or HGU deliver VEIP data service and PPTP Ethernet UNI data service at the same time. In this case, if the ONU cannot automatically adapt and modify the device form, the corresponding service cannot be opened. It can only be solved by changing the ONU device, which increases the communication operating cost

Embodiment 1

[0042] see figure 1 As shown, the embodiment of the present invention provides a method for adapting the ONU device type based on the OMCI service model, which can analyze the service model according to the service issued by the OLT (optical line terminal, optical line terminal), and adapt to the device type according to the analysis result , can flexibly adapt to SFU, HGU or Hybrid, and support PPTP Ethernet UNI data service, VEIP data service, VoIP service and TR-069 management service capabilities. A kind of method based on OMCI business model adaptive ONU device type of the embodiment of the present invention specifically comprises:

[0043]S1: The OLT delivers services to the ONU through the OMCI protocol. The OMCI protocol is a protocol for information exchange between OLT and ONT defined in the GPON (Gigabit-Capable PON, passive optical access system) standard. It is used for the management of ONT by OLT in the GPON network, and the OMCI protocol is in the GPON The hi...

Embodiment 2

[0055] On the basis of Embodiment 1, for the self-adaptive device type according to the business model analysis result, specifically:

[0056] When the result of business model analysis is that no business model is obtained, the ONU adaptive device type is NONE;

[0057] When the business model analysis result is that the PPTP Ethernet UNI data business model is obtained, but the VEIP data business model and TR-069 management business model are not obtained, the ONU adaptive device type is SFU;

[0058] When the business model analysis result is that the VEIP data business model or TR-069 management business model is obtained, but the PPTP Ethernet UNI data business model is not obtained, the ONU self-adaptive device type is HGU;

[0059] When the service model analysis result is to obtain the PPTP Ethernet UNI data service model, and at the same time obtain the VEIP data service model or the TR-069 management service model, the ONU adaptive device type is Hybrid.

[0060] Wh...

Embodiment 3

[0062] On the basis of embodiment 1, the ONU receives the business issued by the OLT, and according to the OMCI protocol message in the business, the specific steps for analyzing and obtaining the business model are:

[0063] S201: The ONU receives the service delivered by the OLT, and stores the OMCI protocol message in the service;

[0064] S202: The ONU analyzes the stored OMCI protocol message to obtain the service model to which the OMCI protocol message belongs.

[0065] The specific steps for the corresponding service implementation unit to implement the service are: ONU checks whether the configuration of the service issued by the OLT is correct, if it is wrong, it will end, and the service will not be sent to the service implementation unit; if it is correct, the ONU will send the service to the corresponding The service realization unit instructs the corresponding service realization unit to implement the service.

[0066] The ONU detects whether the configuration o...

Abstract

The invention discloses a method and system for self-adapting to an ONU (Optical Network Unit) device type on the basis of an OMCI service model, and relates to the technical field of communication access. The method comprises the steps that: S1: an OLT (Optical Line Terminal) issues a service to an ONU by an OMCI protocol; S2: the ONU receives the service issued by the OLT, and according to an OMCI protocol message in the service, analysis is carried out to obtain the service model; S3: the ONU self-adapts to the equipment type according to a service model analysis result; and S4: the ONU indicates a corresponding service implementation unit to carry out service implementation. According to the invention, flexibility and comprehensiveness that the ONU bears the service can be effectivelyimproved.

Description

technical field [0001] The invention relates to the technical field of communication access, in particular to a method for adapting an ONU device type based on an OMCI service model and a system for adapting an ONU device type based on an OMCI service model. Background technique [0002] PON (Passive Optical Network, Passive Optical Network) is currently the most widely used optical access system. It has many advantages such as high bandwidth, high efficiency, high service quality, large coverage and rich user interfaces. It is an ideal technology to realize broadband and comprehensive transformation of access network services. [0003] The type of ONU (Optical Network Unit, optical network unit) factory equipment in PON is generally SFU (single family unit) or HGU (home gateway unit). When it is an SFU type, it can only carry PPTP Ethernet UNI (Physical path termination point Ethernet user network interface, physical path end node Ethernet user network interface) data serv...
