The type of an ONU (Optical Network Unit ) factory device in a PON is generally an SFU (single home Unit) or an HGU (home gateway Unit), and when the ONU factory device is an SFU type, it can only carry a PPTP Ethernet Unit (Physical path termination point Ethernet user Network interface ) data service and a VoIP (Voice over Internet Protocol, Voice over Internet Protocol) service; when the HGU type is used, it can only carry the VEIP (Virtual Ethernet interface point) data service, the VoIP service, and the TR-069(CPE wide area network management protocol) management service.
With the global large-scale application of the PON system, the optical access scene is more and more complex, flexible and changeable. The user requires that the same ONU needs to simultaneously support the PPTP Ethernet UNI data service, the VEIP data service, the VoIP service and the TR-069 management service, but the single equipment type of the current ONU can not meet the application requirements; the same customer accesses the SFU type ONU and the HGU type ONU at the same time, which sharply increases the operation and maintenance cost of the optical access network.
In a conventional situation, the type of the equipment from which the ONU leaves is SFU or HGU, and an OLT (optical line terminal) issues a corresponding service according to the type of the ONU equipment, but in an interworking scenario, especially in an international project, the OLT of each manufacturer is mixed with the ONU, and the OLT does not issue the corresponding service according to the type of the ONU equipment, but issues the service at will according to the operator's requirements, such as issuing a VEIP data service to the SFU, issuing a PPTP Ethernet UNI data service to the HGU, issuing a VEIP data service and a PPTP Ethernet UNI data service to the SFU or the HGU, and the like.

The method for self-adapting the ONU equipment type based on the OMCI service model specifically comprises the following steps:
s1: and the OLT issues services to the ONU through an OMCI protocol. The OMCI protocol is a protocol for information interaction between an OLT and an ONT defined in a GPON (Gigabit-Capable PON, passive optical access system) standard, and is used for the OLT to manage the ONT in a GPON network, and the OMCI protocol is in a high-level control plane in the GPON system.
And when the ONU is started and the access OLT is successfully registered, the OLT issues services to the ONU. For the start registration process of the ONU, the method specifically includes: the method comprises the steps of connecting the power supply of the ONU and starting the ONU, initializing the equipment type of the ONU into NONE after the software mirror image of the ONU is loaded, then inserting an optical fiber into the ONU to access the OLT, carrying out an authentication registration process, when the OLT checks that the authentication information of the ONU is legal, successfully registering the ONU, or else, failing to register the ONU. The authentication information of the ONU includes an SN code (product serial number), a LOID (registration code), a PASSWORD (PASSWORD), and the like.
After the ONU is successfully registered in the OLT, the OLT can issue services to the ONU, and in systems such as GPON, XG-PON, XGS-PON, WDM-PON and the like, the OLT issues services to the ONU through an OMCI protocol, wherein the service types comprise broadband internet access service, voice service, IPTV service, TR-069 management service and the like.

After receiving the OMCI protocol messages related to the service issued by the OLT, the ONU analyzes the OMCI protocol messages according to a service model specified by the G.988 standard. If the service model specified by the G.988 standard can be correctly matched, generating and obtaining a corresponding service model; otherwise, no business model is generated. The business model comprises: PPTP Ethernet UNI data service model, VEIP data service model, VoIP service model and TR-069 management service model. The PPTP Ethernet UNI data service model comprises the following 7 modes: 1, 1: p, N, P, 1: m, N M, 1: MP and N: MP.
For the data service model of the PPTP Ethernet UNI, the establishing process is as follows: the method comprises the steps of firstly creating a geoport, secondly creating a MAC bridge, thirdly creating an ANI (access network interface) side, fourthly creating a GEM (GPON encapsulation mode) interface TP (termination point), fifthly setting an 802.1p map server profile, and sixthly creating a UNI side based on a PPTP Ethernet UNI (user network interface).
For the VEIP data service model, the creating process is as follows: a first step of creating a geomport; secondly, creating an MAC bridge; step three, establishing an ANI side; step four, creating GEMinterworking TP; fifthly, setting 802.1p map service profile; the sixth step creates the UNI side based on the VEIP.
For the VoIP business model, the process of creation is as follows: a first step of creating a geomport; secondly, creating an MAC bridge; step three, establishing an ANI side; step four, setting IP/IPv6host config data; fifthly, setting VoIP config data; the sixth step creates the UNI side based on the PPTP POTS UNI.
For the TR-069 management business model, the process of creation is as follows: a first step of creating a geomport; secondly, creating an MAC bridge; step three, establishing an ANI side; fourthly, creating a UNI side MAC bridge port; fifthly, creating TCP/UDP config data; and the sixth step is to set TR-069 associated ME configuration.
S3: and the ONU self-adapts to the equipment type according to the service model analysis result. The device types are NONE, SFU, HGU and Hybrid. The Hybrid is a combination type of the SFU and the HGU, and the NONE indicates that when the OMCI protocol message is analyzed and no service model is obtained, the type of the adaptive equipment of the ONU is NONE.
S4: and the ONU indicates the corresponding service implementation unit to implement the service. When the service model is obtained and the device type is adapted according to the service model analysis result, the corresponding service implementation unit performs service implementation, such as broadband internet service configuration is issued to the broadband service implementation unit, voice service configuration is issued to the voice service implementation unit, IPTV service configuration is issued to the multicast service implementation unit, and TR-069 management service configuration is issued to the management service implementation unit.
The method for adapting the ONU equipment type based on the OMCI service model obtains the service model by analyzing the OMCI protocol message issued to the ONU service by the OLT, then the ONU adapts the equipment type according to the analysis result of the service model and correspondingly realizes the service, thereby greatly improving the flexibility and the comprehensiveness of the ONU bearing service, being suitable for a multi-service complex application scene, reducing the operation and maintenance cost of an optical access network and enabling the service of the ONU to be opened simply and efficiently.
