In the xPON system, when the ONU equipment at the user side detects a fault or an abnormality, an alarm is generated and reported to O L T equipment, an alarm record table is generated and maintained by O L T equipment, and is used for receiving and storing the alarm detected by O L T and the alarm reported by the hanging equipment, the alarm detected by O L T comprises the alarm record table generated by different modules of the equipment (including but not limited to a CPU, an exchange module, different types of service line cards and the like) and the alarms generated by different interfaces (including but not limited to a PON interface, an upper connection interface, a sensor and the like), all the alarm modules, interfaces and all the alarm generated under the condition that the alarm generated by the hanging equipment share the alarm record table L T, the alarm record table is used for recovering the alarm record table when the alarm generated by the hanging equipment is lost, the alarm record table is used, and when the alarm processing is abnormal, the alarm record table is recovered from the alarm record table when the alarm generated by the alarm record table is full, the alarm record table is used, and the alarm record table is recovered when the alarm processing is used, the alarm record table is recovered, and the alarm record table is recovered from the corresponding alarm record table when the alarm processing time is full alarm record table is used

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
The first embodiment is as follows:
referring to fig. 2, the method for processing the alarm information of the passive optical network device in this embodiment includes:
step 201: an optical line terminal acquires an exclusive network element list;
the exclusive network element list in this step may be created and generated on the optical line terminal, or may be created and generated on other devices and then sent to the optical line terminal. The members in the exclusive network element list are at least one of important modules (including but not limited to at least one of a CPU, a switching control module, a clock module, a service line card, and the like), interfaces, and optical network units, which are specified by the optical line terminal, the network management server, or the operation and maintenance system. Specifically, important modules, interfaces and optical network units can be determined as members of an exclusive network element list according to configuration on an optical line terminal, a human-computer interaction command, configuration requirements of a network management server or other operation and maintenance systems and the like, and the alarm information of the members is stored separately, so that the phenomenon that the alarm information is discarded or important and unrecovered alarm information is covered due to impact on the alarm information caused by mass alarms of other communication equipment is avoided;
step 202: the optical line terminal respectively creates an independent alarm record table for each member in the exclusive network element list;
step 203: the optical line terminal establishes a public alarm record table for storing alarm information of other communication equipment (including modules, interfaces and optical network units) which are members in the non-exclusive network element list; it should be understood that this step may also be performed before the above step 201, or may also be performed simultaneously with the above step 201; in addition, the creation of the independent alarm record table and the public alarm record table may also be: firstly, directly establishing a total alarm record table, then dividing some independent spaces in the total alarm record table to be used as independent alarm record tables respectively, and using the rest spaces as public alarm record tables;
step 204: the optical line terminal detects new alarm information;
the optical line terminal detects new alarm information, namely the optical line terminal detects the alarm information or receives the alarm information sent by other modules, interfaces or units;
step 205: when the optical line terminal determines whether the new alarm information is from a member in the exclusive network element list, if so, go to step 206; otherwise, go to step 207;
step 206: and storing the new alarm information into an independent alarm record table corresponding to the member.
Step 207: and storing the new alarm information into a common alarm record table.
In the embodiment, the independent alarm record table spaces and the public alarm record table space can be set to be independent from each other and cannot occupy or cover each other; of course, according to the actual application scenario, they may occupy or cover each other in some cases. Specifically, after the optical line terminal creates the independent alarm record tables for each member in the exclusive network element list, the method further includes setting a use mode for the independent alarm record table corresponding to each member according to the attribute of each member, where the set use mode in this embodiment includes any one of a fixed mode and a guaranteed mode; wherein:
the fixed mode is that only the alarm information from the member can be stored after the alarm record table space is distributed to the corresponding member; at this time, no matter whether the member generates the alarm information or not, the space of the alarm record table corresponding to the member is always occupied by the member;
the guarantee mode is that after the alarm record table space is allocated to the corresponding member, the alarm information from the member is preferentially stored, and when the alarm record table space is idle, the alarm record table space can be shared out for other members (which can be other members in the exclusive network element list or other devices in the non-exclusive network element list) to use. Therefore, in this embodiment, when the common alarm record table is full or other independent alarm record tables are full, it may be determined whether there is an independent alarm record table with a use attribute being a guaranteed manner and currently in an idle state, and if there is an independent alarm record table, the independent alarm record table may be borrowed for storage.
In this embodiment, the optical line terminal may also dynamically maintain the members (including optical network units, modules or interfaces, etc.) in the exclusive network element list and the corresponding alarm record table according to a human-machine command, a network management command or other operation and maintenance system command; the method specifically comprises the following steps:
when a new member is added in the exclusive network element list, for example, after a newly added optical network unit in a wireless optical network system completes registration authentication, and normally receives management of an optical line terminal, the optical line terminal finds that the optical network unit is in the exclusive network element list, and decides to create a corresponding independent alarm record table for the optical network unit to store alarm information corresponding to the optical network unit; when the newly added optical network unit is not in the exclusive network element list, the public alarm recording table space is directly used for receiving and storing the alarm information corresponding to the optical network unit;
when a member exits from the exclusive network element list, the optical line terminal releases an independent alarm record table created for the member before, and uses the corresponding space as a shared alarm record space; for example, when the onu is deleted on the olt, the olt determines that the onu is in the exclusive network element list, deletes the relevant content in the corresponding exclusive network element list, and releases the corresponding allocated space for use as the public warning record table space.
When a member in the exclusive network element list is in an offline state, the optical line terminal keeps an independent alarm record table of the member. For example, when the optical network unit is offline, the optical line terminal does not process the space of the alarm record table occupied by the optical network unit, and keeps the original alarm record and the attribute thereof of the optical network unit.
In this embodiment, after the optical line terminal detects new alarm information, when an alarm record table (e.g., a corresponding independent alarm record table or a shared alarm record table) corresponding to the new alarm information is not full (i.e., is not overflowed), the optical line terminal receives and stores the corresponding alarm information successively according to time; in this embodiment, the optical line terminal may process the new alarm information by combining the previously acquired alarm priority list in order to avoid the problem of discarding or covering important alarm information when the alarm record table corresponding to the new alarm information is full. The alarm priority list can be generated on the optical line terminal, or generated on other equipment and then sent to the optical line terminal; the alarm priority list contains priority information of each alarm information. When the space of the alarm record table corresponding to the new alarm information is full, the optical line terminal processes the new alarm information according to the alarm priority list, and the process comprises the following steps:
the optical line terminal determines whether the alarm information stored in the alarm record table corresponding to the new alarm information (for example, if the new alarm information corresponds to the shared alarm record table at the time, and the independent alarm record table corresponding to the new alarm information is in the same manner) has a priority lower than that of the new alarm information, if the alarm information exists, the optical line terminal covers an alarm information having a priority lower than that of the new alarm information and generated earliest, and stores the new alarm information in the alarm record table, and the alarm information covered in the embodiment is preferably unrecovered information; if the lowest priority in the stored alarm information in the alarm record table is equal to the priority of the new alarm information, directly discarding the new alarm information or covering an alarm information with the lowest priority and generated earliest according to the default setting of the system to store the new alarm information in the alarm record table; if the priority of the stored alarm information in the alarm record table is higher than that of the new alarm information, the new alarm information is directly discarded.
In this embodiment, when the optical line terminal detects that a certain alarm is recovered (the detection here is that the optical line terminal itself detects or receives a recovery notification sent by another module, interface, or unit), the corresponding alarm information is deleted in the corresponding alarm record table to release the corresponding space. And when the alarm information corresponding to the recovered alarm does not exist in the corresponding alarm record table, directly transmitting the alarm information to an upper network management or other operation and maintenance systems.

In the embodiment, the independent alarm record table spaces and the public alarm record table space can be set to be independent from each other and cannot occupy or cover each other; of course, according to the actual application scenario, they may occupy or cover each other in some cases. Specifically, referring to fig. 4, the optical line terminal 2 further includes an attribute setting module 25, configured to set a use mode for the independent alarm record table corresponding to each member according to the attribute of each member after the independent alarm record table creating module 22 creates the independent alarm record table for each member in the exclusive network element list.

the guarantee mode setting submodule is used for setting that the alarm record table space is distributed to the corresponding member, preferentially storing the alarm information from the member, and sharing the alarm record table space for other members to use when the alarm record table space is free. Therefore, in this embodiment, when the common alarm record table is full or other independent alarm record tables are full, it may be determined whether there is an independent alarm record table with a use attribute being a guaranteed manner and currently in an idle state, and if there is an independent alarm record table, the independent alarm record table may be borrowed for storage.
In this embodiment, the optical line terminal further includes a maintenance module 26, please refer to fig. 5, which is configured to dynamically maintain members (including optical network units, modules, interfaces, etc.) in the exclusive network element list and corresponding alarm record tables according to a human-machine command, a network management command, or other operation and maintenance system command; the method specifically comprises the following steps:

when a member exits from the exclusive network element list, the maintenance module 26 releases the independent alarm record table created for the member before, and uses the corresponding space as a shared alarm record space; for example, when the onu is deleted on the olt, the maintenance module 26 determines that the onu is in the exclusive network element list, deletes the relevant content in the corresponding exclusive network element list, and releases the corresponding allocated space for use as the public warning record table space.
The maintaining module 26 maintains the independent alarm record table of the member when the member is in the offline state in the exclusive network element list.

the O L T exclusive network element list is used for setting and storing members appointed by O L T, network management or other operation and maintenance systems, and comprises important modules/interfaces and ONUs, the O L T alarm priority list is used for storing important key alarm items appointed by O L T, network management or other operation and maintenance systems, and specifically comprises the priority of each alarm message, the priority of each important alarm message can be set independently, the priority of each other alarm message is not set, and the priority of each alarm message is defaulted to be the lowest;
step 802, according to the configuration, man-machine command, network management or other operation and maintenance system requirements on O L T, O L T in xPON adds the relevant module/interface of the specific ONU equipment or O L T itself which is hung below the O L T as a member into an exclusive network element list, respectively allocates independent alarm record table spaces, and determines that the independent alarm record table spaces adopt a fixed mode or a guarantee mode according to the attributes of the independent alarm record table spaces;
in this embodiment, O L T may also directly generate a total alarm record table, and then divide an independent space for each member in the exclusive network element list in the alarm record table as an independent alarm record table corresponding to each member, and the rest are shared alarm record tables, specifically, O L T divides the total alarm record table into a common space and configures corresponding independent spaces for the exclusive network elements according to the module/interface/ONU information configured in the exclusive network element list, where alarms generated by each module/interface/ONU specified in the exclusive network element list are received and stored in the independent alarm record table space, alarms generated by each module/interface/ONU not specified in the exclusive network element list are received and stored in the common alarm record table space, and when the O L T detects a local module/interface or receives an alarm from an exclusive network element, the alarms are sent to the corresponding independent space or shared space of the alarm record table according to the configuration of the exclusive network element list.
The independent alarm record table spaces and the public alarm record table spaces are independent from each other and cannot occupy or cover each other. Each independent alarm recording table space is exclusively or preferentially distributed by a designated module/interface/ONU in a fixed or guaranteed mode, and the public alarm recording table space is shared and commonly used by other modules/interfaces/ONUs. The fixed mode means that after the alarm recording table space is allocated to a designated module/interface/ONU, whether a corresponding alarm is generated or not, the corresponding alarm recording table space is occupied by the module/interface/ONU and cannot be used by other objects; the guarantee mode means that after the alarm record table space is allocated to the designated module/interface/ONU, the module/interface/ONU preferentially uses and occupies the alarm list space, and when the alarm record table space is free, the alarm record table space can be shared to other non-designated modules/interfaces/ONU or used by other members in the exclusive network element list.
And step 803, O L T in xPON sets the priority of different alarms according to the configuration or instruction and generates or updates a related alarm priority list, the high-priority alarm covers the low-priority alarm when the alarm record table is full or under other conflict conditions, and when the public/independent alarm record table space is full, the high-priority alarm enters and is stored in the related public/independent alarm list space and covers the low-priority alarm entry according to a certain strategy.
When O L T detects or receives a new alarm, O L T judges the generation module/interface/ONU information and the alarm priority information, determines the storage space according to the alarm information, and determines the alarm processing mode under the condition that the alarm space is full, when the new alarm priority is higher than the alarm priority already existing in the corresponding alarm record table, the storage space enters the corresponding alarm record table space and covers the earliest generated and unrecovered low-priority alarm in the alarm record table, when the new alarm priority is lower than the alarm priority already existing in the corresponding alarm record table, the alarm is discarded, and when the new alarm priority is the same as the alarm priority already existing in the corresponding alarm record table, the alarm processing mode is covered or discarded according to the O L T default alarm processing mode.
When the O L T detects or receives an alarm recovery notice, the alarm recovery notice is recovered in the corresponding alarm record table space according to the information of the alarm generation module/interface/ONU.
Step 804, in an xPON system, when the newly added ONU completes registration authentication and normally accepts O L T management, O L T determines to newly add a corresponding independent alarm record table space or use a public alarm record table to receive and process the alarm of the corresponding ONU equipment according to the configuration of the ONU equipment in an exclusive network element list;
when the newly registered authentication ONU is in the exclusive network element list of O L T, O L T divides a new independent alarm record table space for receiving and storing the alarm information corresponding to the ONU, and when the newly registered authentication ONU is not in the exclusive network element list of O L T, O L T uses a common alarm record table space to receive and store the related alarm.
When the space of the alarm recording table is not full, corresponding alarm information is received and stored successively according to time; when the space of the alarm record table is full, confirming the related alarm priority according to the alarm priority list and adopting a corresponding processing mode;
step 805, when the ONU equipment is kept online, the O L T maintains the members (related ONU or O L T related module/interface) in the exclusive network element list and the independent alarm record table space in response according to the human-computer command, the network management or other operation and maintenance system command;
when the O L T detects that an alarm occurs, the alarm is sent to the corresponding alarm record table space according to the alarm occurrence position, specifically, when the alarm information comes from a member in the exclusive network element list, the relevant alarm is sent to the independent alarm record table space allocated to the alarm information, and when the alarm information does not come from a member in the exclusive network element list, the relevant alarm is sent to the public alarm record table space.
When the members (modules/interfaces/ONU information) in the exclusive network element list or the attributes such as the priority and the like are changed, the O L T releases or newly adds the corresponding independent alarm record table space according to a certain strategy, and updates and maintains the use mode of the alarm record table space.
Step 806, when the ONU equipment is off-line, O L T does not process the occupied alarm record table space, and keeps the original alarm record and the use attribute of the ONU;
step 807, when the ONU equipment is deleted on O L T, O L T judges the ONU attribute, deletes the relevant content in the corresponding exclusive network element list, and releases the corresponding allocated space to be used as the public warning record table space;
step 808, the O L T reports the newly added alarm and the alarm recovery notification message to the network manager and other operation and maintenance platforms in real time, so as to ensure the alarm synchronization of the communication equipment and the network manager and other operation and maintenance platforms.
The foregoing is a more detailed description of the present invention that is presented in conjunction with specific embodiments, and the practice of the invention is not to be considered limited to those descriptions. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
