Description

Technical Field

[0001] This invention relates to the field of communications, and specifically to a method and apparatus for determining alarm boundaries for voice leased lines based on a command channel. Background Technology

[0002] The AGCF (Access Gateway Control Function) is a device attached to the fixed network of the core network IMS (IP Multimedia Subsystem) for external enterprise access to intermediate PBX (Private Branch Exchange) and other equipment. It can connect to thousands of different voice leased lines. The customer-side PBX connects to the AGCF via TG (Trunk Gateway). The AGCF is the control plane, and the TG is the media plane.

[0003] Current monitoring methods rely on unreachable MTP (Message Transfer Part) destination signaling point alarms on the AGCF side to monitor the operation of the leased line from that office. If an MTP destination signaling point unreachable alarm is issued from a certain office, it indicates a complete service interruption for that office. Based on static information from customer access records, the system contacts the customer to confirm whether the service interruption is due to customer-side issues; however, there is no method to determine if a transmission interruption caused the service interruption. This approach cannot accurately determine whether a problem with the transmission fiber optic cable is causing the service interruption, thus affecting the progress of fault repair. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a voice leased line alarm delimitation method and apparatus based on command channel to overcome or at least partially solve the above problems.

[0030] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0031] Figure 1 A flowchart illustrating a voice leased line alarm delimitation method based on a command channel according to an embodiment of the present invention is shown. Figure 1 As shown, the method for determining alarm boundaries for voice leased lines based on command channels specifically includes the following steps:

[0032] Step S101: Obtain the first alarm command and the second alarm command.

[0033] The first alarm command is an alarm command from the AGCF access gateway control function unit. Specifically, the first alarm command is an alarm command indicating that the destination signaling point is unreachable for devices of the AGCF access gateway control function unit type. The first alarm command includes information such as: location information = destination signaling point code = 0xDxxx1, source signaling point code = 0xDxxx2, network identifier = XX network, exchange number = 6xx, exchange name = NBXXX+XX fleet (6xx), destination signaling point index = 6xx, destination signaling point name = NB_A+XX fleet (6xx), etc. Based on the first alarm command, it can be determined that an alarm has occurred on the voice leased line.

[0034] The second alarm command is a transmission alarm command, which includes alarm types such as R_LOS and ETH_LOS. Based on the second alarm command, the cause of the alarm can be determined to be a transmission interruption.

[0035] Step S102: Perform multi-layer parsing on the first alarm command and concatenate the alarm service port information.

[0036] When performing multi-level parsing on the first alarm command, such as Figure 2 As shown, the process is performed layer by layer, querying the relay group where the service is located in the first alarm command to obtain various information required for the service port information, such as interface board type, board group number, optical port number, chassis number, and slot number. Specifically, the first alarm command is parsed to first obtain the local direction number from the location information. As shown in step S101, the parsed first alarm command obtains the local direction number as 6xx. Based on the local direction number and the first specified command, the device identifier corresponding to the relay group is determined. The first specified command is the LST TG command under AGCF. Through the LST TG command, TG is specified as the obtained local direction number, and various information corresponding to the local direction number is obtained, from which the device identifier corresponding to the relay group is obtained, as shown below:

[0037] +++ AGCF

[0038] O&M #3xx

[0039] %%LST TG:TG=6xx;%%--Location number

[0040] RETCODE=0 Operation successful

[0041] Basic Information

[0042] --------

[0043] Relay group number = 6xx

[0044] Relay group name = NBXXX + XX fleet

[0045] Source signaling point code = 0Dxxx2

[0046] Destination signaling point code = 0Dxxx1

[0047] Device ID = 10.1xx.1xx.9x:x000 -- Device Identifier

[0048] Network identifier = XX network

[0049] …

[0050] ---END

[0051] Based on the determined device identifier and the second specified instruction, the corresponding media gateway information is further obtained. The second specified instruction is the LST MGW instruction under AGCF. Through the LST MGW instruction, the EID is specified as the obtained device identifier, and the media gateway information corresponding to the device identifier is obtained. The media gateway information is obtained from it, as shown below:

[0052] +++ AGCF

[0053] O&M #2xx

[0054] %%LST MGW:EID = "10.1xx.1xx.9x:x000";%%--Device Identifier

[0055] RETCODE=0 Operation successful

[0056] Media gateway information

[0057] -------------

[0058] Equipment ID = 10.1xx.1xx.9x:x000

[0059] Media Gateway ID = NULL

[0060] Media gateway index = 1

[0061] Media gateway description = TZXXX01

[0062] Gateway group number = 65xxx

[0063] Session boundary controller = 65xxx

[0064] …

[0065] ---END

[0066] Through the above processing, it can be determined that the relay group of the alarm corresponding to the first alarm command is located in the media gateway obtained above.

[0067] Then, based on the media gateway information and the third specified instruction, the interface board type, board group number, optical port number, etc. of the corresponding plug-in board are obtained. The third specified instruction is the LST MTP2LNK instruction. By specifying LNKNO as the obtained local area code through the LST MTP2LNK instruction, the corresponding information is obtained, from which the interface board type, board group number, optical port number, etc. are obtained, as shown below:

[0068] LST MTP2LNK:LNKNO=6xx;

[0069] TZXXX01

[0070] +++ HXXXXI UXX8X00

[0071] O&M #2XXXXX

[0073] RETCODE=0 Execution successful

[0074] Query MTP2LNK

[0075] ------------

[0076] Link number = 6xx

[0077] Link name = NB_X + XX Fleet 1

[0078] Link set index = 1xx

[0079] Integer interface ID = 6xx

[0080] Text-based interface ID = NULL

[0081] Link type = MXX2_6XX_FOR_XXXA

[0082] Interface board type = SxL

[0083] Interface board group number = 2

[0084] Light slogan = 1

[0085] E1T1 identifier = E1

[0086] …

[0087] ---END

[0088] Based on the above information, we can obtain that the interface board type is SxL, the interface board group number is 2, and the optical port number is 1. The above is just an example; the actual values ​​should be obtained according to the specific implementation.

[0089] Based on the obtained interface board type, board group number, optical port number, and the fourth specified instruction, the chassis number and slot number of the insertion board are obtained. The fourth specified instruction is the LST BRD instruction. Using the LST BRD instruction, BT is specified as the obtained interface board type, and BN is the interface board group number, to retrieve the slot record table, from which the chassis number and slot number of the insertion board are obtained, as shown below:

[0090] LST BRD:LM = BXXN, BT = SxL, BN = 2; -LM is specified according to the implementation and can be set to a specific value.

[0091] TZXXX01

[0092] +++ HXXXXI UXX8X00

[0095] RETCODE=0 Execution successful

[0096] Slot Record Sheet

[0097] ----------

[0098] Frame number = 2

[0099] Slot number = 2

[0100] Hardware type = MSxL

[0101] …

[0102] ---END

[0103] Based on the slot record table above, we can obtain that the frame number is 2 and the slot number is 2. The above is just an example; the actual values ​​should be obtained based on the specific implementation.

[0104] The service port information includes media gateway information, interface board type, optical port number, chassis number, and slot number. The acquired media gateway information, interface board type, optical port number, chassis number, and slot number are concatenated in a specified order, such as media gateway information-chassis number-slot number-interface board type-optical port number, to obtain the alarm's service port information, TZXXX01-B02-02-SxL-optical port 1. The media gateway information can also be converted to correspond to the service circuit for subsequent queries, but this will not be elaborated here. The specified order is set according to the implementation situation and is not limited here.

[0105] Step S103: Determine the corresponding service circuit information based on the service port information.

[0106] Based on the spliced ​​service port information, query the service circuit view, such as... Figure 3 As shown, the service port information of port A, such as TZXXX01-B02-02-SxL-Optical Port 1, is obtained, along with the corresponding service circuit information, which specifically includes the service circuit name. Each obtained service circuit is a transmission circuit on the same optical port.

[0107] Step S104: Query the corresponding transmission circuit information based on the service circuit information to obtain the port information and alarm information of the transmission port from the first designated end to the second designated end.

[0108] Since all service circuits are optical port transmission circuits, you can choose any one of the above service circuit information to query the service circuit and transmission circuit correspondence view to obtain the transmission circuit name. For example... Figure 4 As shown, the view corresponding to the service circuit and transmission circuit can be directly queried based on the service circuit name to obtain the transmission circuit name. The transmission port information for the corresponding first and second designated terminals can then be queried based on the transmission circuit name, such as... Figure 5 As shown in the figure, the diagram displays the port information for the A-Z transmission ports, yielding the A-end transmission port xxx-XX City XX District XX Town XXXX-XXX-XXX and the Z-end transmission port xxx-XX City XX District XX Town XXXX-XXX. Based on the first and second specified end transmission ports obtained through querying, the alarm commands associated with the first and second specified end transmission ports are further queried. Specifically, the transmission alarm commands associated with the first and second specified end transmission ports are queried.

[0109] Step S105: Match the alarm command of the first specified end-to-second specified end transmission port with the specified alarm type of the second alarm command, and complete the port delimitation of the transmission alarm based on the matching result.

[0110] The alarm commands for the first-specified-second-specified transmission port are matched with the specified alarm types contained in the second alarm command. The specified alarm types in the second alarm command include, for example, R_LOS and ETH_LOS. If the transmission alarm command for the first-specified-second-specified transmission port contains any of these specified alarm types, the match is successful, and the port for the transmission alarm can be defined as the first-specified-second-specified transmission port. Taking R_LOS as the transmission alarm at end A and R_LOS as the transmission alarm at end Z as an example, the following information can be obtained:

[0111] TZXXX01-B02-02-SxL-Optical Port 1 connects XX service circuits, mainly including XX voice leased line services for the XX fleet.

[0112] A-end transmission alarm: xxx-XX City XX District XX Town XXXX-XXX-XXX R_LOS

[0113] Z-end transmission alarm: xxx-XX City XX District XX Town XXXX-XXX R_LOS

[0114] Furthermore, the above information can be output in the preprocessing information field of the first alarm command to facilitate the delimitation of the first alarm command and clarify that the voice leased line alarm is caused by a transmission alarm.

[0115] If the transmission alarm command of the first designated end to the second designated end transmission port does not contain the above-specified alarm type, the match fails, and it is determined that the alarm of the voice leased line is not caused by the transmission alarm, resulting in the following information:

[0116] TZXXX01-B02-02-SxL-Optical Port 1 connects XX service circuits, mainly including XX voice leased line services for the XX fleet.

[0117] A-end transmission alarm: xxx-XX City XX District XX Town XXXX-XXX-XXX No alarm

[0118] Z-end transmission alarm: xxx-XX City XX District XX Town XXXX-XXX No alarm

[0119] The voice leased line alarm delimitation method based on the command channel provided by this invention involves multi-layer parsing of the first alarm command to obtain the service port information of the alarm, and finally determining the corresponding first designated end-second designated end transmission port by querying. By matching the alarm information of the first designated end-second designated end transmission port with the second alarm information, it can be determined whether the voice leased line alarm is caused by a transmission alarm, facilitating port delimitation of transmission alarms and improving the accuracy and efficiency of delimitation.
