Description

Information identification method and device

Technical Field

The present application relates to the field of optical communication technologies, and in particular, to an information identification method and apparatus.

Background

As the demand of users for bandwidth continues to increase, "optical access to copper and optical access to copper" have been the irreversible trend of access networks. Passive Optical Network (PON) systems have been rapidly developed in recent years as a low-cost optical fiber access means providing gigabit per second (Gbps) bandwidth. Meanwhile, a higher generation of ten gigabit passive optical network (xgpon) and ten gigabit symmetric passive optical network (xgspon) have been deployed on a large scale. The PON technology refers to a point-to-multipoint (P2 MP) optical fiber access technology, which is composed of an Optical Line Terminal (OLT) on a central office side, an Optical Network Unit (ONU) or an Optical Network Terminal (ONT) on a user side, and an Optical Distribution Network (ODN).

With the large-scale laying and application of networks related to the PON, the number of optical fibers is huge, and the network combing requirement exists. Network carding needs to be done for two points: 1. identifying whether an ONU or an ONT is connected below the branch optical fiber to find out port resources which can be used; 2. the on-line ONU or ONT serial number can be acquired and identified so as to map and record with the branch of the optical splitter, thereby facilitating later management and maintenance.

In the related art, the tested optical fiber needs to be unplugged in the detection process to identify whether the ONU or the ONT is connected below the branch optical fiber. Thus, a service interruption may be caused.

At this time, the branched optical fiber may be clamped by a clamping device to produce a certain bending of the optical fiber. The holding device can collect an optical signal generated by bending the optical fiber and identify the optical signal, thereby identifying information of the ONT connected with the branch optical fiber. Because the test fiber does not need to be unplugged, the information of the ONT can be identified on the premise of not interrupting the service.

In one possible implementation manner, the widths of the plurality of first time slots may include a first width and/or a second width, and the first width and the second width are different.

Wherein a combination of widths of the plurality of first slots allocated to the second device may be used for information identifying the second device; the second device transmits uplink data on a plurality of first time slots.

Based on the above scheme, the OLT may allocate a plurality of first time slots, which may identify ONT information, to the ONTs, and the ONTs may send uplink data on the first time slots. At this time, the branched optical fiber may be clamped by a clamping device to produce a certain bending of the optical fiber. The holding device can collect an optical signal generated by bending the optical fiber and identify the optical signal, thereby identifying information of the ONT connected with the branch optical fiber. Since the test fiber does not need to be unplugged, the information of the ONT can be identified without interrupting the service.

Based on the above scheme, the information of the ONT or the ONU can be identified by the combination of two different widths, i.e. the first width and the second width, and the identification of the information of the ONT or the ONU can be realized.

The fourth device may determine widths of a plurality of first time slots to which the first optical signal corresponds based on a pulse envelope of the first optical signal. The fourth device may determine information of the second device transmitting the first optical signal based on a width of the plurality of first slots.

Based on the above scheme, when identifying the sequence number of the ONT, the uplink data sent by the ONT can be detected, and the timeslot width carrying the uplink data is detected and judged, so that the rate of the detected signal is reduced. Because the corresponding signal rate is low, the serial number can be recovered only by simple receiving and sampling, and the information corresponding to the ONT can be acquired while the service of the optical fiber is identified.

Detailed Description

Hereinafter, terms of art related to the embodiments of the present application will be explained and explained.

1) The width of a slot, alternatively referred to as the slot width, may refer to the length of one slot. Referring to fig. 1, the one time slot may be a continuous time domain resource, as shown by a in fig. 1. Alternatively, the one time slot may be a non-continuous time-frequency resource, and there may be a free time-domain resource in the one time slot, as shown in b in fig. 1.

Hereinafter, an information identification method provided in the embodiments of the present application will be described with reference to the drawings.

At present, the number of optical fibers is huge, so that the network combing requirement exists. Wherein, network carding needs two points: first, it is identified whether an ONU or an ONT is connected below the branch fiber to find out a port resource that can be used. And secondly, the on-line ONU or ONT serial number can be acquired and identified so as to be mapped and recorded with the branch of the optical splitter, thereby facilitating later management and maintenance.

In the related art, a branch optical fiber to be measured can be unplugged and connected to an OLT simulation terminal capable of simulating the function of the OLT. If the tail end of the branch optical fiber is terminated with the ONU or the ONT, a communication link can be established, and the OLT analog terminal can acquire the serial number information of the ONU through the communication link and store and record the serial number information as a combing result. However, in the detection process, the tested optical fiber needs to be unplugged, and this operation inevitably causes the corresponding ONT to temporarily interrupt normal service and continue the whole operation process, thereby deteriorating user experience. In addition, the OLT analog terminal has complex hardware energy supply requirements, and the cost is increased.

In addition, when optical fibers are combed, the branch optical fibers can be clamped by the detection equipment for clamping the optical fibers so that the optical fibers can be bent to a certain extent, light leakage can exist when the optical fibers are bent, and whether the optical fibers are idle or not is judged by detecting whether leaked light exists in the uplink direction or not, so that network combing is realized. However, in the detection process, only whether the link has light or not can be detected, so as to determine whether the fiber resource is available, and therefore, the ONU or ONT serial number of the branch fiber cannot be identified for acquisition and identification.

The information identification method provided by the embodiment of the application is used for identifying information such as ONU or ONT serial number of the branch optical fiber. The information identification method provided by the embodiment of the application can be applied to the communication system 200 shown in fig. 2. The communication system 200 may include a first device 210 and at least one second device 220. The first device 210 may transmit control transmission information to the at least one second device 220, and the at least one second device 220 may transmit the transmission information to the first device 210.

The communication system 200 may be an optical communication system, such as a PON system. The PON system may be a gigabit-capable passive optical network (GPON) system, an Ethernet Passive Optical Network (EPON) system, a 10G ethernet passive optical network (10 Gb/s ethernet passive optical network, 10G-EPON) system, a 10G gigabit-capable passive optical network (10 XG-PON) system, or a 10G symmetric passive optical network (10-gigabit-capable passive optical network, XGs-PON) system, etc. The TDM PON system is a point-to-multipoint (point 2multiple point, p 2mp) system.

As an example, referring to fig. 3A, the optical communication system may include at least an OLT and a plurality of ONTs, with the OLT communicating with the plurality of ONTs, respectively. In this embodiment, the optical communication system may also include an OLT and a plurality of ONUs, where the OLT communicates with the plurality of ONUs respectively, which is not specifically limited in this embodiment, and the ONT is described as an example in the following. Referring to FIG. 3A, the OLT communicates with n ONTs through an optical splitter. In FIG. 3A, n ONTs are ONT1, ONT2, \8230;, ONTn, respectively. Each ONT emits light, or is described as transmitting an optical signal, on a designated time slot allocated by the OLT.

Fig. 3A shows only a networking structure of first-stage light splitting, and in the implementation process, two-stage or multi-stage light splitting may be performed, that is, a secondary light splitter is connected below a branch of the light splitter, and the principle is the same as that of networking of first-stage light splitting. Referring to fig. 3B, based on the networking architecture of fig. 3A, an ODN structure diagram is shown. The ODN network mainly includes an Optical Distribution Frame (ODF), an optical cable connector box, an optical splitter, and an optical fiber connector.

For PON systems, OLT to ONT are called downstream, and a continuous broadcast mode is used. The ONTs to the OLT are called as upstream, and a time division multiplexing burst mode is adopted, that is, the OLT allocates the transmission time slots of the ONTs according to a certain rule, and only in the allocated time slots, a specific ONT can perform upstream signal optical transmission.

Referring to fig. 3c, the olt may transmit transmission time slots allocated to the ONT1, the ONT2 and the ONT3. Wherein, the ONT can determine the transmission time slot allocated to itself in the allocation information of the transmission time slot. As shown in fig. 3C, ONT1 may determine that transmission slot 1 is a transmission slot allocated to itself, ONT2 may determine that transmission slot 2 is a transmission slot allocated to itself, and ONT3 may determine that transmission slot 3 is a transmission slot allocated to itself. After receiving the sending time slot, the ONT can send the information of the sending time slot corresponding to the ONT to the user side. Referring to fig. 3D, the user terminal may transmit uplink data on the transmission time slot allocated by the OLT. The ONT may transmit the uplink data sent by the user side to the OLT.

Referring to fig. 4, an exemplary flowchart of an information identification method provided in an embodiment of the present application may include the following operations:

s401, the OLT sends configuration information of the time domain resources, and the corresponding ONTs receive the configuration information of the time domain resources.

The configuration information of the time domain resource may be used to indicate a time slot in which the ONT transmits uplink data. The configuration information of the time domain resource may include widths of a plurality of first time slots allocated to the ONTs. A combination of the widths of the plurality of first time slots may be used for information identifying the ONT. Wherein the information of the ONT may include at least one of: the serial number of the ONT, the manufacturer information of the ONT and the port number of the OLT adopted when the ONT is connected with the OLT.

The following description will be given by taking the serial number as an example. In a PON system, each ONT has a unique coded identity, called a serial number. Typically, the serial number is represented by 32 bits of binary data, and the OLT can know the serial number of each ONT. The OLT may identify the serial numbers of the ONTs by a combination of the widths of the first plurality of time slots allocated to the ONTs.

S402, the ONTs send the uplink data, and the corresponding OLT receives the uplink data.

The ONT can send the uplink data to the OLT on a plurality of first time slots allocated by the OLT.

Based on the above scheme, the OLT may allocate a plurality of first time slots, which may identify information of the ONTs, to the ONTs, and the ONTs may send uplink data on the first time slots. At this time, the branched optical fiber may be clamped by a clamping device to cause a certain bending of the optical fiber. The holding device can collect an optical signal generated by bending the optical fiber and identify the optical signal, thereby identifying information of the ONT connected with the branch optical fiber.

Hereinafter, the widths of the plurality of first time slots allocated to the ONTs will be described. For convenience of description, the information of the ONT is taken as the serial number of the ONT as an example for explanation. It should be understood that the serial number of the ONT at the information of the ONT may further include the manufacturer information of the ONT and the port number of the OLT used when the ONT is connected to the OLT.

In one possible implementation, a width of two slots may be defined. For example, a first width X is defined ₁ For "1", a second width X is defined ₂ Is used to identify "0" and vice versa. Referring to fig. 5, the width of the time slot T2 represents "1", the width of the time slot T3 represents "0", and the sequence shown in fig. 5 is 1010. It should be understood that the width of the time slots in fig. 5 is merely exemplary. The OLT may allocate a plurality of first time slots to the ONTs according to the known serial numbers of the ONTs, and the width of the first time slots may be a first width and/or a second width. The sequence of widths of the plurality of first time slots may identify a sequence number of the ONT.

In one example, the OLT may sequentially allocate a plurality of first time slots to the ONTs. Wherein, the sequence of the widths of the plurality of first time slots allocated by the OLT for the ONTs may indicate the sequence numbers of the ONTs. Referring to fig. 6A, a plurality of first time slots allocated by the OLT to a certain ONT are shown. In fig. 6A, since the width sequence of the plurality of first slots is "11011000", the ONT has a sequence number of "11011011000". Alternatively, the sequence "11011000" may be converted to decimal, and then the ONT has a serial number of "216".

Based on the above scheme, when identifying the sequence number of the ONT, the uplink data sent by the ONT can be detected, and the timeslot width carrying the uplink data is detected and judged, so that the rate of the detected signal is reduced. Because the corresponding signal rate is low, the serial number can be recovered only by simple receiving and sampling, and the serial number of the corresponding ONT can be acquired while the service of the optical fiber is identified.

Optionally, referring to fig. 6A, a free time slot exists between adjacent first time slots of the plurality of first time slots allocated by the OLT to the ONT. The OLT may also allocate the free time slot to the ONT for traffic transmission. For example, the OLT may allocate a free time slot to an ONT other than ONT1 shown in fig. 6A for traffic transmission. The width of the time slot between the aforementioned plurality of first time slots may be different from the width of any one of the plurality of first time slots. Alternatively, the width of the time slot between the plurality of first time slots may be the same as the width of a certain first time slot, and the application is not particularly limited.

Optionally, referring to fig. 6A, there is also a free time slot in the first time slot. The OLT may also allocate a free time slot in the first time slot to the ONT for traffic transmission. For example, the OLT may allocate a free time slot within the first time slot to an ONT other than ONT1 shown in fig. 6A for traffic transmission.

Based on the above scheme, the OLT may allocate an idle time slot to the ONT for service transmission, which may reduce the impact on the service requirement due to the transmission rate of the signal being reduced.

The time length or the number of the first time slots that the OLT allocates to the ONTs and can identify the sequence numbers may be predefined. The OLT may allocate, within a predefined duration, a plurality of first time slots to the ONT according to the sequence number of the ONT, where a sequence of widths of the plurality of first time slots may identify the sequence number of the ONT. Alternatively, the number of times the OLT allocates the ONT with the plurality of first time slots whose width sequence may identify a sequence number may be less than or equal to a predefined number of times. When the number of times or duration that the OLT allocates the plurality of first time slots to the ONTs satisfies the predefined number of times or duration, the OLT may continue to allocate a plurality of first time slots, of which the width sequence may identify the ONT sequence number, to the next ONT. The OLT may randomly select an ONT to allocate a plurality of first time slots to the ONT, so as to implement round robin for all ONTs.

Optionally, after completing the round-robin for all the ONTs once, the OLT may also perform round-robin for all the ONTs again until the predefined number of round-robin is satisfied or the detection is completed.

In another example, the OLT may allocate time slots for transmitting uplink data to a plurality of ONTs, respectively. The sequence of the widths of the time slots allocated by the OLT to multiple ONTs may respectively indicate the sequence numbers of the corresponding ONTs. The ONT may determine a time slot allocated to itself among a plurality of time slots allocated by the OLT and transmit uplink data on the time slot allocated to itself. Wherein, since the frequency domain resources used by different ONTs are different, the ONT may determine the time slot allocated to itself from the frequency domain resources of the plurality of first time slots. Referring to fig. 6b, the olt may allocate a time slot for transmitting uplink data for 2 ONTs. The frequency domain resource of the first time slot is f1, and the frequency domain resource of the second time slot is f2. And the ONT1 and the ONT2 receive the plurality of time slots allocated by the OLT, and determine the time slots allocated to the ONT from the plurality of time slots according to the frequency domain resources which can be used by the ONT. For example, ONT1 may determine that time slot 1, time slot 2, time slot 3, and time slot 4 are allocated to itself, and ONT2 may determine that time slot 5, time slot 6, time slot 7, and time slot 8 are allocated to itself. Wherein the sequence of the widths of time slot 1, time slot 2, time slot 3 and time slot 4 may indicate the sequence number of ONT1, and the sequence of the widths of time slot 5, time slot 6, time slot 7 and time slot 8 may indicate the sequence number of ONT 2. In fig. 6B, the width sequence of slot 1, slot 2, slot 3, and slot 4 is "0101", and thus the sequence number of ONT1 may be "0101". Optionally, the serial number of ONT1 is "5" when it is converted to decimal. Likewise, the serial number of ONT2 may be "0110", which when converted to decimal, the serial number of ONT2 is "6".

The duration or the number of times that the OLT allocates the first time slots, which can identify the sequence numbers, to the ONTs may be predefined. The OLT may allocate a plurality of first time slots, which may identify serial numbers, to the ONTs according to the serial numbers of the ONTs within a predefined time period. The number of times that the OLT allocates the first time slots, in which the width sequence can identify the sequence number, to each of the ONTs may be less than or equal to a predefined number of times.

Based on the above scheme, when identifying the sequence number of the ONT, the uplink data sent by the ONT may not be detected, and the timeslot width carrying the uplink data is detected and determined, so that the rate of the detected signal is reduced. Because the corresponding signal rate is low, the serial number can be recovered only by simple receiving and sampling, and the serial number corresponding to the ONT can be acquired while the service of the optical fiber is identified.

Optionally, referring to fig. 6B, a vacant time slot exists between adjacent first time slots of the plurality of first time slots allocated by the OLT to the plurality of ONTs. The OLT may also allocate the free time slot to the ONT for traffic transmission. Wherein, the width of the time slot between the first time slots may be different from the width of any time slot allocated to a plurality of ONTs. Alternatively, the width of the time slot between the first time slots may be the same as the width of a certain time slot allocated to a certain ONT, which is not specifically limited in this application. Optionally, referring to fig. 6B, there is also a free time slot in the first time slot. The OLT may also allocate a free time slot in the first time slot to the ONT for traffic transmission.

In another possible implementation, the width of the second time slot may also be defined. Wherein the second time slot may be a start flag of information of the ONT. The OLT may allocate at least one second time slot for the ONTs, which may temporally precede the plurality of first time slots. It should be noted that the width of the second time slot may be the same as or different from the width of the plurality of first time slots. For example, the width of the second slot may be defined as a third width, which is different from the first width and the second width. Then, the OLT may allocate at least one second time slot and a plurality of first time slots to the ONTs. Wherein the at least one first time slot is a start flag bit of information of the ONT, the plurality of first time slots represent data bits of the sequence number, and the sequence of widths of the plurality of first time slots can identify the sequence number of the ONT. Fig. 6C is a schematic diagram of widths of the second time slot and the plurality of first time slots. The width of the second time slot shown in fig. 6C is different from the width of any one of the first time slots, and only one second time slot is shown in fig. 6C.

It should be understood that the widths and numbers of the second and first slots in fig. 6C are merely exemplary.

Hereinafter, a method for the OLT to allocate the first time slot and the second time slot to the ONTs will be described with specific examples.

Example 1

Referring to fig. 7a, the olt may allocate a plurality of first time slots and at least one second time slot for ONT1, ONT2 and ONT3, respectively. The OLT may allocate a second time slot T1, as shown in fig. 7A, for ONT1, and a plurality of first time slots, T2, T3, T2 and T3, respectively. Here, the width of the time slot T2 may represent "1", and the width of the time slot T3 may represent "0". The width of the time slot T1 is different from the widths of the time slots T2 and T3. In fig. 7A, the serial number of ONT1 may be "1010", and when it is converted to decimal, the serial number of ONT1 may be "10".

In addition, in fig. 7A, there are free time slots between the second time slot and the first time slot, and between the adjacent first time slots (the remaining ONT time slots in fig. 7A). The OLT may assign it to ONT2 and ONT3 for traffic transmission. At the same time, the gap in the middle is allocated to other ONTs for normal service transmission, and after the cyclic transmission is performed for a certain number of times according to the time slot allocation characteristic, the opportunity of allocating time slots according to the sequence number is switched to the next ONT, so that the round-robin for all the ONTs is realized. For example, the OLT may allocate the second time slot and the first time slot to ONT1 for a period of time or repeatedly. After the OLT allocates the second time slot and the first time slot to the ONT1 for a time duration or a number of times that satisfies a predefined time duration or a predefined number of times, the OLT may allocate the first time slot and the second time slot to the ONT 2. And so on to implement a round robin for all ONTs.

Example 2

Referring to fig. 7b, the OLT may allocate a plurality of first time slots and at least one second time slot for ONT1, ONT2 and ONTX, respectively, so as to enable the OLT to perform uplink time slot width control through the serial number of the ONT. Unlike example 1, the OLT in example 2 performs the above-described operation simultaneously for all ONTs. In one or more uplink frames, the time slot containing the identification sequence number of more than one ONT is not used for polling other ONTs after one ONT completes the time slot allocation of the identification sequence number for multiple times.

Referring to fig. 7B, the OLT may allocate the second time slot and the plurality of first time slots according to time domain resources that can be used by ONT1, ONT2, and ONTX, respectively. In fig. 7B, the OLT allocates a second time slot T1 for the ONT1, and a plurality of first time slots T2, T3, T2 and T3, respectively. The OLT allocates a second time slot T1 for ONT2, and a plurality of first time slots T3, T2 and T3, respectively. The OLT allocates a second time slot T1 for the ONTX, and the plurality of first time slots are T2, T3, and T3, respectively. The OLT may carry configuration information of the first time slot and the second time slot allocated by the ONT1, the ONT2, and the ONTX in one or more frames upstream. Optionally, the OLT may carry configuration information of the first time slot and the second time slot allocated to the ONT1, the ONT2, and the ONTX in an upstream single frame. The ONT1, ONT2 and ONTX may determine the time slots allocated to themselves according to the frequency domain resources that may be available to themselves, respectively. ONT1, ONT2 and ONTX may each carry upstream data in a time slot allocated to itself.

In fig. 7B, the serial number of ONT1 is "1010", and when it is converted to decimal, the serial number of ONT1 may be "10". The serial number of ONT2 is "0010", and when it is converted to decimal, the serial number of ONT2 may be "2", and the serial number of ONTX is "1100", and when it is converted to decimal, the serial number of ONTX may be "12".

Example 3

Referring to fig. 7c, the olt may perform uplink slot width control by the serial number of the ONT. The time slots allocated by the OLT for the ONT1 are T1, T2, T3, T2 and T3, respectively. T1 is a start flag bit of the serial number of ONT1, and T2, T3, T2 and T3 are data bits of the serial number of ONT 1. The serial number of ONT1 is "1010", and when it is converted to decimal, the serial number of ONT1 may be "10".

Alternatively, the OLT may assign time slots identifying serial numbers to the ONTs one by one, as shown in example 1. Alternatively, the OLT may allocate time slots identifying sequence numbers for multiple ONTs at the same time, as shown in example 2.

Referring to fig. 7C, a small number of time slots allocated to other ONTs (the remaining ONT time slots in fig. 7C) may be interleaved within the time slot allocated to ONT 1. For example, the OLT may allocate a free time slot inside the time slot to ONT2 and ONTX for traffic transmission.

Based on the above scheme, the OLT performs corresponding uplink timeslot allocation according to the serial number of the ONT, greatly reduces the transmission rate of serial number information, and implements ONT determination on the optical fiber and identification of the serial number of the corresponding ONT on the premise of not interrupting service by combining with curved light leakage detection at the branch optical fiber.

Through the above scheme, a method for allocating an uplink timeslot of an ONT in this embodiment is described. When the ONT sends uplink data, the holding device may be used to bend the branch optical fiber and detect an optical signal of the branch optical fiber, thereby implementing identification of the time slot width.

Referring to fig. 8, a clamping apparatus according to an embodiment of the present application is provided. When carding the optical fibers, the branched optical fibers can be clamped by a clamping device to make the optical fibers bend to a certain degree. When the ONT transmits uplink data, optical leakage exists in optical fiber bending, and the clamping equipment can detect the leaked optical signal. The clamping device comprises an optical fiber bending chuck, a photoelectric conversion device and a subsequent amplifying and processing unit, after the optical fiber is bent, the leakage light is converted into an electric signal through the photoelectric conversion device, the electric signal enters the restoring and processing unit through the pulse width sampling circuit, and the time slot width is identified to obtain the serial number of the ONT. Optionally, the clamping device may have a display screen for displaying the related result, and may also have a storage function. Optionally, the clamping device may have an electrical signal amplification unit, and after the leakage light is converted into an electrical signal by the photoelectric conversion device, the electrical signal may be amplified and then passed through the pulse sampling circuit.

Hereinafter, the operation of the clamping device will be described with reference to fig. 9.

Referring to fig. 9, an exemplary flowchart of an information identification method provided in an embodiment of the present application may include the following operations:

s901, the clamping device detects the pulse envelope of the first optical signal.

Wherein the first optical signal may be a signal over a corresponding plurality of first time slots. The clamping device may convert the first optical signal into a first electrical signal, thereby detecting a pulse envelope of the first electrical signal. Optionally, the clamping device may amplify the first electrical signal and then detect the pulse envelope.

S902, the clamping device determines widths of a plurality of first time slots corresponding to the first optical signal based on the pulse envelope of the first optical signal.

Referring to fig. 10, the pulse envelope includes the pulse width of the electrical signal over a plurality of first time slots. The holding device may identify pulse widths of the plurality of first time slots and determine a sequence of widths of the plurality of first time slots based on the predefined first width and second width. The clip device may determine a serial number of the ONT transmitting the first optical signal according to the sequence of widths of the plurality of first time slots.

In one possible implementation, the holding device may also detect the second optical signal, since the slot width of the start flag bit (i.e., the width of the second slot) that can identify the ONT serial number is also defined. The second optical signal is converted from the electrical signal at the second time slot. Referring to fig. 10, the pulse envelope includes the pulse width of the electrical signal over one or more second time slots. The holding device may identify the pulse widths of the one or more second time slots and determine a sequence of widths of the one or more second time slots. The clamping device may determine that the sequence of widths of the second time slot is used to mark the starting position of the ONT sequence number. Then the clip device may determine that a sequence of widths of a plurality of first time slots following the one or more second time slots may be used to identify the serial number of the ONT.
