An operator develops IPTV service on The basis of Fiber To The Home (FTTH). In a Passive Optical Network (PON), a Home Network management system Unit (HGU) and a Single Home Unit (SFU) can open an IPTV service.
In the process of starting up the IPTV service, a start-up signal sent by a set-top box passes through an HGU or an SFU and an Optical Line Terminal (OLT), and then reaches a plurality of Broadband Remote Access Servers (BRASs), the plurality of BRASs respectively inquire whether to grant continued Access to a Dynamic Host Configuration Protocol (DHCP) system from the same Authentication, Authorization, Accounting, AAA) Server, and the AAA Server allows one of the BRASs to continue accessing the DHCP system. The DHCP System assigns an IP address to the set-top box and also assigns a Domain Name System (DNS) server address. After the set-top box obtains the IP address distributed by the DHCP, the domain name information of the terminal management system is carried to access the DNS server. After the DNS server resolves the IP address of the terminal management system, the set top box accesses the terminal management system according to the IP address of the terminal management system, and the terminal management system issues a user name and a password to the set top box. And finally, the set-top box accesses the IPTV platform according to the user name and the password issued by the terminal management system, and the set-top box is successfully started and can use the IPTV service after the IPTV platform is successfully verified.
Referring to fig. 1, a schematic flowchart of a method for locating a fault of an interactive network television according to an embodiment of the present invention is shown, where the method 100 for locating a fault of an interactive network television according to an embodiment of the present invention shown in fig. 1 includes the following steps:
s110, verifying that the set top box is not on line by calling a terminal management system, and inquiring that the HGU or the SFU is on line by an Operation and Maintenance Center (OMC) system, wherein the HGU or the SFU receives normal optical power.
In S110, the terminal management system can remotely query whether the set-top box is online, the running state of the HGU, and the port state of the HGU.
As an example, the Terminal Management System may be a Digital Home Management Platform (DHMP), a Remote Management System (RMS) of a fixed network Terminal, or an Integrated Terminal Management System (ITMS).
In some embodiments, the control terminal management system sends an inquiry to the set-top box whether to be online, and if the set-top box returns a confirmation instruction within a fixed time, the set-top box is judged to be online. And if the set top box does not return a confirmation instruction within a fixed time, judging that the set top box is off-line.
In S110, the OMC system can query the running status of the HGU and SFU. As an example, the operating states of an HGU or SFU on an OMC system can be classified as UP, LOS, and POWER OFF. Wherein, UP represents HGU or SFU online; LOS indicates that the link state of the optical link between the OLT and the HGU or between the OLT and the SFU is abnormal, POWER OFF indicates that the POWER supply of the HGU or the SFU is abnormal.
Therefore, in some embodiments, the step of querying, by the OMC system, that the HGU or the SFU is online in S110 specifically includes:
and querying the running state of the HGU or the SFU on the OMC system.
And determining the running state of the HGU or the SFU to be UP, and judging that the HGU or the SFU is on line.
And determining the running state of the HGU or the SFU as LOS, and positioning the link fault between the OLT and the HGU or between the OLT and the SFU.
In some embodiments, when a link between the OLT and the HGU or between the OLT and the SFU fails, the set-top box user is advised to check whether the fiber between the set-top box and the HGU or between the set-top box and the SFU is bent. And if the user checks that the optical fiber is not bent and the fault is still not solved, the user is informed to wait for maintenance personnel to check the optical path problem at home.
And determining the running state of the HGU or the SFU to be POWER OFF, and positioning the POWER failure of the HGU or the SFU.
In some embodiments, when a power failure of the HGU or SFU is located, the set-top box user is advised to check whether the HGU or SFU is powered up.
In some embodiments, the terminal management system can query the running state of the HGU, and cannot query the running state of the SFU. Therefore, when the set-top box is connected with the SFU, whether the SFU is online or not is directly inquired through the OMC system; when the set-top box is connected with the HGU, the starting fault of the interactive network television can be further accurately positioned by inquiring the running state of the HGU in the terminal management system.
Thus, in some embodiments, the step of the OMC system querying the HGU or SFU online in S110 includes:
and the terminal management system inquires that the HGU is not online, and then the OMC system inquires that the HGU is online.
In some embodiments, when the set-top box is connected to the HGU, after the terminal management system is invoked to verify that the set-top box is not online, the terminal management system needs to query whether the HGU is online.
As an example, the running state of the HGU in the terminal management system may be divided into UP and DOWN states, and when the running state of the HGU is UP, it indicates that the HGU is online, and the start fault of the interactive network television may be further located in the terminal management system; when the running state of the HGU is DOWN, the HGU is off-line, and when the HGU is off-line, the running state of the HGU can be further inquired in the OMC system.
Therefore, in some embodiments, before the step of determining that the link between the home system unit HGU or the single home unit SFU and the optical line termination OLT apparatus is reachable in S120, the method further includes:
and verifying that the set top box is not on line by calling the terminal management system, and inquiring that the HGU is on line by the terminal management system.
And inquiring that the port for opening the IPTV service on the HGU is normal on the terminal management system.
In some embodiments, the terminal management system records an operating state of a port, which opens an IPTV service, on an HGU. As an example, the operation state of the port on the HGU that opens the IPTV service may be divided into two states, UP and DOWN. Wherein UP indicates that the port is normal and DOWN indicates that the port is abnormal.
Therefore, in other embodiments, before the step of determining that the link between the home system unit HGU or the single home unit SFU and the optical line termination OLT apparatus is reachable in S120, the method further includes:
and verifying that the set top box is not on line by calling the terminal management system, and inquiring that the HGU is on line by the terminal management system.
And inquiring the abnormity of a port for opening the IPTV service on the HGU by the terminal management system, and positioning the fault of a link between the set top box and the HGU.
As an example, in the terminal system, the state of a LAN port on the HGU, which opens the IPTV service, is DOWN. The user of the set-top box may be advised to try whether the set-top box can be normally powered on after restarting the set-top box. And if the set top box can not be normally started, checking the network cable connection between the set top box and the HGU. And if the fault still can not be solved, informing the set top box user to wait for maintenance personnel to go to the door for maintenance.
In some embodiments, after the step of querying, by the terminal management system, that a port on the HGU that opens the IPTV service is normal, the method further includes:
and confirming that the MAC address of the connecting equipment on the port for opening the IPTV service is not matched with the IP address in the opening state on the terminal management system.
In some embodiments, the terminal management system may query the MAC address of the connection device on the port for activating the IPTV service and the IP address corresponding to the port connection device when the IPTV service is activated. When the MAC address of the connecting equipment on the port for opening the IPTV service is not matched with the IP address corresponding to the port connecting equipment when the IPTV service is opened, the set top box can be determined to be not matched with the HGU, so that the fault reason can be further positioned.
The set top box is positioned to not match the HGU.
In some embodiments, after the set top box is located and not matched with the HGU, it may be determined to a set top box user whether a routing device exists between the set top box and the HGU, or whether the set top box has an HGU port inserted incorrectly.
In S110, the received optical power of the HGU or SFU may be queried on the OMC system. When the receiving optical power of the HGU or the SFU is lower than the sensitivity of the HGU or the SFU to receive optical signals, the communication data packet is lost, and the interactive network television is in failure.
In S110, after the step of the HGU or the SFU receiving the normal optical power, the method further includes:
and the receiving optical power of the HGU or the SFU is lower than the receiving optical signal sensitivity, and the fault that the receiving optical power of the HGU or the SFU is low is positioned.
In some embodiments, when the receiving optical power of the HGU or the SFU is lower than the receiving optical signal sensitivity, a set-top box user is advised to check whether the optical fiber in the HGU or the SFU is bent or not, and when the fault problem still cannot be solved, a maintenance worker is dispatched to get on the door for maintenance.
And S120, if the link between the HGU or the SFU and the OLT equipment is judged to be accessible, inquiring the authentication failure record of the AAA server to the BRAS on a plurality of BRASs according to the MAC address of the set-top box respectively.
In S120, because the AAA server may receive information of multiple BRASs requesting upward access to the DHCP system, only one BRAS server is allowed to continue upward access to the DHCP system. Therefore, it is necessary to determine whether AAA service allows the BRAS to access DHCP system upwards with the MAC address of the set-top box on a plurality of BRAS respectively.
In some embodiments, the determining that the link between the HGU or the SFU and the OLT device is reachable in S120 specifically includes:
and S121, calling the MAC learning table of the HGU or the SFU on the OLT to judge whether the link between the HGU or the SFU and the OLT can be reached.
In S121, in the initial state, the MAC learning table of the HGU or the SFU of the OLT does not have any MAC address and corresponding port information of the HGU or the SFU. When a data frame sent by the HGU or the SFU reaches the OLT through the PON port on the OLT, the MAC address of the corresponding HGU or the MAC address of the corresponding SFU is recorded on the MAC learning table of the HGU or the SFU of the OLT, and the information of the corresponding PON port is recorded.
In some embodiments, the MAC learning table of the HGU or SFU may be invoked on the OLT through telnet protocol (remote terminal protocol).
As an example, when a data frame of the HGU arrives at the OLT through the first PON port, a MAC address of the HGU and information of the first PON port are recorded on a MAC learning table of the HGU of the OLT.
And S122, judging that the link between the HGU or the SFU and the OLT equipment is reachable.
In some embodiments, whether the MAC address of the HGU or the SFU is recorded may be queried in a MAC learning table of the HGU or the SFU of the OLT, and if the MAC address of the HGU or the SFU is recorded, it is determined that the link between the HGU or the SFU and the OLT device is reachable.
The MAC learning of the HGU or the SFU may be invoked on the OLT through S121 and S122 to determine that the link between the HGU or the SFU and the OLT device is reachable. However, when fault location of the interactive network television is performed, there is also a case where a link between the HGU or the SFU and the OLT apparatus is not reachable.
Therefore, in some embodiments, after the HGU or the SFU receives normal optical power in S110, the method further includes:
and calling an MAC learning table of the HGU or the SFU on the OLT to judge that the link between the HGU or the SFU and the OLT is unreachable.
And positioning the fault to be an IPTV service VLAN configuration error.
In some embodiments, if the MAC address of the HGU or the SFU is not queried in the MAC learning table of the HGU or the SFU of the OLT, it is determined that the link between the HGU or the SFU and the OLT is unreachable.
In some embodiments, the locating fault is an IPTV service VLAN configuration error, and the IPTV service VLAN configuration of the HGU may be checked on the terminal management system, the IPTV service VLAN configuration may be checked on the OLT, and the IPTV service VLAN configuration may be checked on the BRAS, respectively.
In some embodiments, after the positioning fault configures an IPTV service VLAN error, the IPTV service VLAN may be reconfigured by the corresponding VLAN management system.
S130, inquiring the authentication failure record of the AAA server to all BARS according to the MAC address of the set-top box, and positioning the link failure between the set-top box and the BRAS.
In S130, under the condition that the set-top box is normally powered on, multiple BRASs carry the MAC address of the set-top box to request the AAA server to continue accessing the DHCP system upward, and the AAA server only allows one BRAS to continue accessing the DHCP system upward.
In some embodiments, whether the BRAS has an authentication failure record corresponding to the MAC address of the set top box can be queried according to the MAC address of the set top box through a telnet protocol.
As an example, an instruction to check the reason for the failure of user authentication may be sent to the BRAS to inquire on the BRAS whether the AAA server allows the BRAS to continue accessing the DHCP system upward through the MAC address of the set-top box. As a specific example, the instruction to check the reason for the failure of the user authentication may be dis aaa online-fail-record.
At S130, when the AAA server does not allow other BRAS to continue accessing the DHCP system, an authentication failure record is generated on the BRAS. When the authentication failure record is not inquired on the BRAS, the AAA server can judge that the BRAS is allowed to continuously access the DHCP system or the physical link between the set-top box and the BRAS is not passed.
Therefore, in some embodiments, after S120, further comprising:
and the AAA server does not inquire the authentication failure record of the BRAS and the BARS does not inquire the acquired IP address of the set-top box according to the MAC address of the set-top box, and the link failure between the set-top box and the BRAS is positioned.
In some embodiments, the BRAS may be configured to query whether the set-top box has obtained the IP address based on the MAC address of the set-top box by sending an instruction to the BRAS to display the online user by MAC address. As an example, the instruction to display the online user by MAC address may be specifically a dis access-user-MAC-address.
In some embodiments, after sending the instruction of displaying the online user according to the MAC address to the BRAS, the condition that the set top box is not queried online or the query fails according to the MAC address of the set top box can be classified as that the set top box has not queried the acquired IP address.
S140, according to the fact that the MAC address of the set top box does not inquire the authentication failure record of the AAA server to the BRAS and the fact that the set top box obtains the IP address is inquired on the BARS according to the MAC address, and the fault is located by the dynamic host configuration protocol DHCP system according to the MAC address of the set top box and the system log of the DHCP.
In S140, whether the process of the DHCP system assigning the IP address to the set-top box is normal may be confirmed through a DHCP system log (e.g., syslog).
In some embodiments, the process of the DHCP server assigning an IP address to the set-top box includes: firstly, the set-top box sends a DHCP DISCOVER message in a broadcasting mode to search a DHCP server. Secondly, after receiving the DHCP DISCOVER message sent by the set-top box, the DHCP server selects an IP address to send to the set-top box in a DHCP OFFER message mode. Then, the set-top box sends DHCP ADDRESS message in broadcast mode after receiving the IP address. Finally, after receiving the DHCP ADDRESS message, the DHCP server returns a DHCP ACK message in a broadcasting mode if the IP address is distributed to the set-top box; and if the IP address cannot be allocated to the set-top box, returning a DHCP NAK message in a broadcasting mode.
Therefore, the method for determining whether the process of the DHCP system for allocating the IP address to the set-top box in S140 is normal specifically includes:
and inquiring whether a system log corresponding to the MAC address exists on a DHCP system according to the MAC address of the set-top box.
If the system log corresponding to the MAC address cannot be inquired, the network fault between the BRAS and the set top box is located.
In some embodiments, after locating a network failure between a BRAS to a set top box, a packet capture test may be performed on the BRAS to resolve the failure.
Whether the last record in the system log is the relevant information of the DHCP ACK message is inquired in the DHCP system log.
And if the last record in the system log is the relevant information of the DHCP ACK message, confirming that the process of the IP address distributed to the set top box by the DHCP system is normal.
If the last record in the system log is not the relevant information of the DHCP ACK message, whether the last record in the system log is the relevant information of the DHCP ACK message or not in a fixed time period is judged.
And if the last record in the system log is the relevant information of the DHCP ACK message in a fixed time period, confirming that the process of the IP address distributed to the set-top box by the DHCP system is normal.
If the last record in the system log is not the relevant information of the DHCP ACK message in a fixed time period, the fault that the DHCP allocates the IP address fails is located.
As an example, whether the last record in the system log becomes the relevant information of the DHCP ACK message is checked in 5S, and if the last record in the system log in 5S is not the relevant information of the DHCP ACK message all the time, the failure that the DHCP allocates the IP address is located.
In some embodiments, the method for locating a fault of an interactive network television according to the embodiments of the present invention further includes:
and verifying the set top box to be on-line by calling a terminal management system, inquiring the last authentication failure information corresponding to the set top box on the IPTV platform, and positioning the IPTV service fault according to the last authentication failure information.
In the step of verifying the set-top box is online by calling the terminal management system, the set-top box is verified to be online in the terminal management system, which indicates that the DHCP system has allocated an IP address for the set-top box, so that the fault can be positioned in the IPTV platform, the last authentication failure information corresponding to the set-top box can be inquired in the IPTV platform, and the fault can be positioned according to the last authentication failure information.
In some embodiments, the IPTV service failure may be divided into: binding errors, user name not present, user name or password errors, and other reasons.
In some specific embodiments, when it is determined that the IPTV service failure is a binding relation error, it may be determined whether a channel of the set top box changed by the set top box user is a regular channel.
In some specific embodiments, when it is determined that the IPTV service failure is caused by another reason, the maintenance personnel may be notified to troubleshoot the failure reason from an Electronic Program Guide (EPG) side or query an account problem on the IPTV platform.
