Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Example 1
In order to solve the problem that management data cannot be communicated between edge ONTs in the existing FTTR system, as shown in fig. 1, the invention provides a method for communicating data between edge ONTs in the FTTR system. In the method provided by the invention, the optical gateway and the edge ONT sending the request are interacted by adopting double-layer OMCI information, and the optical gateway and the edge ONT responding the request are interacted by adopting single-layer OMCI information.
It should be noted that the dual-layer OMCI message is obtained by nesting OMCI messages. When one edge ONT is to send a message to other edge ONTs, the message to be sent is encapsulated with an AVC message in the extended OMCI message, the message format is shown in fig. 2.
The Transaction correlation identifier field in the AVC message is set to a preset interval (e.g., 0x0000-0x7 FFF) reserved for nesting OMCI between edge ONTs, and for 16 edge ONTs, each edge ONT uses a range of n×2048 to n×2048+2047, where N is 0-15. While the remaining range 0x8000-0xFFFF is still used for normal OMCI messages between the optical gateway and the edge ONT.
The Entity class field in the AVC message is set to a preset value (e.g., 0 xFFBB) to characterize the OMCI message for communication between edge ONTs.
The Entity instance field in the AVC message is used to indicate the ONU ID of the destination edge ONT of this message, indicating to which edge ONT the message is specifically sent. Specifically, if the Entity instance field is a preset broadcast address (e.g., 0 xFFFF), it indicates that the message is a broadcast message, and the message content needs to be sent to all other edge ONTs.
The Message contents field in the AVC Message contains a complete OMCI Message, which is the original OMCI Message sent by one edge ONT to another edge ONT.
Message Type is used to distinguish Message types, such as AVC Message or Set Message;
device identifier is similar to a random number and is used to identify a particular OMCI message, each using the same method.
The other fields of the special AVC message still follow the requirements of the extended OMCI message.
The edge ONT is also realized by OMCI nesting when receiving messages sent by other edge ONTs through the optical gateway, and specifically, the messages are packaged by expanding Set messages in the OMCI messages, and the message format is shown in figure 3.
The Transaction correlation identifier field in the Set message is Set to a preset interval (e.g., 0x0000-0x7 FFF) reserved for nesting OMCI between edge ONTs, and for 16 edge ONTs, each edge ONT uses a range from n×2048 to n×2048+2047, where N is 0-15. While the remaining range 0x8000-0xFFFF is still used for normal OMCI messages between the optical gateway and the edge ONT. If this message is a reply message to other edge ONTs, the field value is consistent with the previous AVC message.
The Entity class field in the Set message is Set to a preset value (e.g., 0 xFFBB) to characterize the OMCI message for communication between edge ONTs.
The Entity instance field in the Set message is used to indicate the ONU ID of the source edge ONT of the message, indicating which edge ONT the message is specifically sent from.
The Message contents field in the Set Message contains a complete OMCI Message, which is the original OMCI Message sent by one edge ONT to another edge ONT.
The other fields of the special Set message still follow the requirements of the extended OMCI message.
Example 2
Based on the encapsulation rule of the double-layer OMCI message provided in the above embodiment 1, the embodiment of the present invention provides a method for sending management data between edge ONTs, as shown in fig. 4, which mainly includes the following steps:
step 10, edge ONT is encapsulated according to the format described in embodiment 1. One edge ONT takes the OMCI message sent to the other edge ONT as the data part of the AVC message, and carries out special processing on Transaction correlation identifier, entity class and Entity instance fields, then checks the length of the AVC message to ensure that the length of the AVC message does not exceed the maximum length defined by the extended OMCI message, and finally calculates the checksum and sends the message to the optical gateway.
Step 20, after the optical gateway receives the AVC message, it checks Transaction correlation identifier, the Entity class field, if the encapsulation requirement of embodiment 1 is met. The message is considered an OMCI message between the edge ONTs rather than a message sent by the edge ONT to the optical gateway.
Step 30, after the optical gateway receives the AVC Message meeting the requirements of embodiment 1, the field Transaction correlation identifier of the AVC Message is recorded, and the Message contents field in the AVC Message is extracted at the same time, so as to be used as a new complete OMCI Message. The optical gateway modifies the Transaction correlation identifier field of the OMCI message so as not to conflict with Transaction correlation identifier already in use by the current optical gateway. After recalculating the checksum, the message is sent to the corresponding edge ONT according to the edge ONT ID of the reply request in the AVC message without changing the other message contents.
Step 40, after receiving the reply of the edge ONT of the response request, the optical gateway takes the OMCI message as the data part of the Set message, and performs special processing on the Transaction correlation identifier, the Entity class and the Entity instance fields, wherein Transaction correlation identifier is the Transaction correlation identifier value of the AVC message reserved in step 30. The Entity class is 0xFFBB,Entity instance as the ONU ID of the source edge ONT. After the optical gateway calculates the checksum, the data is sent to the edge ONT that sent the AVC message in step 20.
Step 50, after the edge ONT receives the Set message, check Transaction correlation identifier, the Entity class field, if the encapsulation requirement of implementing column 1 is met. The message is considered an OMCI message between the edge ONTs rather than a message sent by the edge ONT to the optical gateway.
Step 60, when the edge ONT receives the Set Message meeting the requirements of embodiment 1, the Message contents field in the Set Message is extracted as a new complete OMCI Message.
Note that: not all OMCI messages will answer to the initiator, and if in step 30 the corresponding edge ONT of the received message does not need to answer, then the corresponding absence of the following steps 40-60.

Example 5
Based on the above embodiment 2, this embodiment describes a specific usage scenario of the present invention: replacement of edge ONT.
As shown in fig. 5, the present invention provides a method for replacing an edge ONT LOID, which includes LOID1, LOID 2, and edge ONT1 and edge ONT 2.
When the FTTR system is in actual use, a plurality of edge ONTs are hung under one optical gateway, the use scene of each edge ONT is different, and different configurations are carried out according to different use scenes. The configuration of each edge ONT is bound to a specific LOID. The mapping relation between the LOID and the configuration is stored in the optical gateway.
In the figure, the edge ONT1 uses the LOID1, the edge ONT2 uses the LOID 2, when two edge gateways trigger the replacement action through a device key or the like in the same time interval, the two edge gateways autonomously complete the exchange of the LOID through the peer-to-peer communication by the method ONT1 and ONT2 in the embodiment 2, the optical gateway (main gateway) does not participate in the process of exchanging contents and does not sense the exchange process, the ONU1 is used as the edge ONT for sending the request to set the LOID1 to the edge ONT2, and the ONU2 is also used as the ONT for sending the request to set the LOID 2 to the edge ONT1. The two edge ONTs receive the new LOID, save it, and register with the optical gateway with the new LOID.
Example 6
Based on the above embodiment 2, this embodiment illustrates another specific usage scenario of the present invention: synchronization of wireless roaming information between edge ONTs
As shown in fig. 6, the present invention provides a method for implementing wireless roaming information between sub-routes in an FTTR system, which does not need to process roaming information through a main route (controller) and forward the roaming information, but directly transmits point-to-point between two sub-routes.

There are many processes of access authentication, transmission encryption and the like in the wireless signal, encryption authentication data are continuously updated between the AP and the terminal, when the wireless terminal starts to access to the AP1, the AP1 records a series of access information connected with the wireless terminal, when a mobile phone roams to the AP2 to access, the AP2 can rapidly broadcast the information of the wireless terminal to all APs of the whole FTTR system, at the moment, the AP1 can rapidly know that the wireless terminal has accessed the AP2, the information of the authentication encryption and the like recorded by the wireless terminal can be directly transmitted to the AP2 through the method of the example 2 in a point-to-point mode through an optical link, and the AP2 and the wireless terminal can directly use the information of the encryption authentication and the like just to carry out wireless data transmission without renegotiation, so that the wireless terminal equipment can rapidly and seamlessly roam between the APs. That is, in step 10, the AP2 sends an AVC message, where the Entity instance is not a specific edge ONU ID, but is a broadcast address, for example, 0xFFFFF, and after the optical gateway in step 30 receives the AVC message, the optical gateway sends the AVC message to other corresponding edge ONTs managed by the optical gateway.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
