Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an energy-saving method, device, equipment, and storage medium for an optical line terminal. Background Art

[0002] An optical line terminal (OLT) is the starting point of a passive optical network (PON) and is connected to a core switch through an Ethernet cable. The main function of the optical line terminal is to convert frames and transmit signals for the passive optical network, and to coordinate the multiplexing of optical network terminals to share upstream transmission.

[0003] Currently, the OLT can work in cooperation with an optical network unit (ONU) to provide broadband access services in a fiber optic communication system, that is, the OLT can forward data packets sent by the upper-layer network to the ONU.

[0004] However, in the above technical solution, the data packets to be forwarded may be of non-real-time interaction type or real-time interaction type. If the OLT forwards both non-real-time interaction type data packets and real-time interaction type data packets to the ONU in a real-time sending manner, the real-time sending of non-real-time interaction type data packets by the OLT will cause unnecessary resource waste and increase the energy consumption of the OLT. Summary of the Invention

Rather, the use of words such as "exemplary" or "for example" is intended to present concepts in a specific manner.

[0038] Before introducing the energy-saving method of the optical line terminal provided by the embodiments of this application in detail, the implementation environment and application scenarios of the embodiments of this application will be introduced first.

[0039] First, the application scenarios of the embodiments of this application will be introduced.

[0040] An optical line terminal (OLT) is the starting point of a passive optical network (PON) and is connected to a core switch via an Ethernet cable. An OLT usually only has communication functions, converts frames and transmits signals for the PON, and coordinates the multiplexing of optical network terminals to share upstream transmission, and does not have IT functions.

[0041] OLT usually complies with standards such as gigabit passive optical network (GPON) or Ethernet passive optical network (EPON), which stipulate the transmission methods and protocols of data in a fiber optic communication system.

[0042] Currently, OLT usually only has communication functions and does not have information technology (IT) functions. OLT devices mainly use PON technology to communicate with ONUs. It converts data from the upper-layer network (such as the metropolitan area network) into optical signals suitable for transmission in optical fibers. In this process, technologies such as time division multiplexing (TDM) are adopted. TDM technology divides the data of different users on the time axis, enabling the data of multiple users to be transmitted time-division multiplexed on the same optical fiber, greatly improving the utilization rate of the optical fiber. Moreover, OLT devices also use wavelength division multiplexing (WDM) technology to increase the network capacity. By using optical signals of different wavelengths, data of multiple channels can be transmitted simultaneously in the same optical fiber, realizing the bearing of multiple services. For example, different types of service data such as voice, data, and video can be transmitted simultaneously on one optical fiber.

[0043] During the interaction with ONUs, OLT devices communicate through the methods of downstream broadcast and upstream time division multiple access (TDMA). In the downstream direction, OLT sends data in a broadcast form to all connected ONUs, and each ONU receives its own data according to its own identifier. In the upstream direction, ONUs send data to OLT within the allocated time slots, and OLT receives and processes this data.

[0044] The network architecture of fiber to the home is as Figure 1 shown. The network architecture of fiber to the home includes: optical line terminal 101, multiple optical splitters (such as optical splitter 102, optical splitter 103), and multiple optical network units connected to the home (such as optical network unit 104, optical network unit 105, optical network unit 106). The optical line terminal 101 is responsible for converting the signals of the public switched telephone network, Internet access service, and cable television service into optical signals and transmitting them through optical fibers. The optical splitter distributes the optical signals to multiple optical network units, and each optical network unit then converts the signals into electrical signals and provides them to home users.

[0045] However, in the above technical solution, the data packets to be forwarded may be of non-real-time interaction type or real-time interaction type. If OLT forwards both non-real-time interaction type data packets and real-time interaction type data packets to ONUs in the way of real-time sending, the real-time sending of non-real-time interaction type data packets by OLT will cause unnecessary resource waste and increase the energy consumption of OLT.

[0046] In summary, how to reduce the energy consumption of the optical line terminal during data forwarding has become a technical problem to be solved urgently.

[0047] To solve the above problems, the embodiments of the present application provide an energy-saving method for an optical line terminal. The energy-saving method for the optical line terminal provided by the embodiments of the present application is applied to the scenario of reducing the energy consumption of the optical line terminal. In the embodiments of the present application, the optical line terminal can receive the target data to be forwarded sent by the upper-layer network to the optical network unit and determine the data type of the target data to be forwarded. If the data type of the target data to be forwarded belongs to the real-time interaction type, the optical line terminal will judge the current operating state of the optical network unit, and when the optical network unit is in the low-energy consumption mode, temporarily store the target data to be forwarded in the database of the content delivery network. In this way, for data with low real-time requirements, the optical line terminal can temporarily store the data in the database of the content delivery network when the optical network unit is in the low-energy consumption mode, reducing the number of times of waking up the optical network unit, thereby realizing the energy-saving function of the optical line terminal during the data forwarding process. Moreover, by temporarily storing the data in the database of the content delivery network, the data transmission delay or retransmission problem caused by the low-energy consumption state of the optical network unit can be reduced.

[0048] The implementation environment of the embodiments of the present application will be introduced below.

[0049] As Figure 2 shown, it is a schematic diagram of a communication system provided by the embodiments of the present application. The communication system may include: an upper-layer network 201, an optical line terminal 202, and at least one optical network unit (such as optical network unit 203, optical network unit 204). Among them, the optical line terminal 202 can be connected to the upper-layer network 201, the optical network unit 203, and the optical network unit 204 in a wired / wireless manner.

[0050] Among them, the upper-layer network 201 can be used to send target data and receive request messages. The upper-layer network 201 can be used to send the target data of the local network to the optical line terminal 202 and the optical network unit (such as optical network unit 203, optical network unit 204). The upper-layer network 201 can also be used to receive the data request message of the optical line terminal 202, where the data request message is used to request the first data.

[0051] The optical line terminal 202 can be used to obtain the data type of the target data to be forwarded. The optical line terminal 202 can also be used to send the target data to be forwarded to optical network units (such as optical network unit 203 and optical network unit 204). The optical line terminal 202 can also be used to store the target data to be forwarded in the database of the content delivery network. The optical line terminal 202 can also be used to obtain the operating modes of the optical network units (such as optical network unit 203 and optical network unit 204), where the operating modes of the optical network units include a low-power consumption mode and a non-low-power consumption mode. The optical line terminal 202 can also be used to receive the data request messages sent by the optical network units. The optical line terminal 202 can also be used to send the target data to the optical network units (such as optical network unit 203 and optical network unit 204).

[0052] It should be noted that in the embodiment of this application, a computing power board (such as IT hardware integrating a processor, a memory, etc.) can be added to the optical line terminal 202, and a content delivery network (CDN) database is deployed, with CDN functions. And the content delivery network database can be used to store the target data.

[0053] The optical network units (such as optical network unit 203 and optical network unit 204) can be used to send data request messages to the optical line terminal 202. The optical network units (such as optical network unit 203 and optical network unit 204) can also be used to receive the target data in the database of the content delivery network in the optical line terminal 202.

[0054] In the embodiments of the present application, the OLT is an enhanced OLT, that is, an OLT deployed with a CDN database. In an all-service access network, multiple services with different transmission standards and network structures can coexist in the same OLT device. Therefore, the enhanced OLT has multiple functions to adapt to various combinations. For example, the link types of the enhanced OLT include point-to-point link type, time division multiple access passive optical network (TDMA PON) link type, wavelength routed passive optical network (WR PON), link type, and time and wavelength division multiple access (TWDMA) link type; for example, the architecture types of the enhanced OLT include fiber to the curb (FTTC) architecture type, fiber to the building (FTTB) architecture type, fiber to the home (FTTH) architecture type, fiber to the antenna (FTTA) architecture type; for example, the types of ONUs of the enhanced OLT include single family unit (SFU), small business unit (SBU), multi dwelling unit (MDU), multi dwelling unit (MTU), home gateway unit (HGU); for example, the quality of service (QoS) or service type of the enhanced OLT can ensure that critical applications can be preferentially processed and their performance is not affected by other traffic.

[0055] It should be noted that in cases where PON collisions need to be avoided and protection handovers are required, the enhanced OLT can manage various configurations simultaneously in a more stringent event speed real-time manner. Moreover, in the service supply chain, the enhanced OLT can be connected to the main networks and protection networks of one or several operators, making the enhanced OLT a hub node capable of collecting the configuration data and behaviors required by all its connected network terminals.

[0056] It can be understood that by introducing enhanced OLT functions, not only can the behaviors expected by end-users (such as the acceptance degree of ONU energy consumption costs by users) be captured, but also the tolerance of users to the possible side effects of low-power mode operations can be expressed. On the other hand, the enhanced OLT can also eliminate some of the side effects generated on the remote server during local low-power mode operation, thereby avoiding or minimizing downtime in the service chain.

[0057] In some embodiments, the optical line terminal 202 can be an energy-saving device for the optical line terminal. The optical line terminal 202 can include: a transponder and an energy-saving content distribution network. Among them, the energy-saving content distribution network contains a database. As Figure 3 shown, the data traffic of the upper-layer network is input into the OLT device. The database in the energy-saving content distribution network of the OLT is used to store data. The transponder of the OLT is used to process and schedule data, convert the electrical signal into an optical signal, and transmit it to multiple ONUs through the optical fiber link. The ONU converts the optical signal back into an electrical signal and connects it to the user's terminal device.

[0058] It should be noted that in the downlink transmission direction, the OLT can identify whether the connected ONU is in the low-power mode stage through the authorization and parameter configuration of the OLT state machine. Based on the permission settings of the end-user and the type of service purchased by the user, the OLT can activate and optimize the local energy-saving function.

[0059] In the download or push mode, for non-real-time services, the local enabler in the OLT can be analogous to a CDN resource and can perform "store and forward" operations at an appropriate time to delay the sending of data to the target device. When the PON network performs sleep monitoring, this method may increase the maximum delay time of the low-power mode between two wake-up cycles. To detect which content is restricted by this additional power-saving function, this information needs to be clearly declared in the relevant database, so that the OLT can activate this function when the conditions are met.

[0060] Combined with the interaction process of the optical line terminal 202 with the upper-layer network 201 and at least one optical network unit (such as optical network unit 203, optical network unit 204) in the above communication system, the operation process of the energy-saving device of this optical line terminal is as Figure 4As shown in the figure. When the OLT receives the target data sent by the upper-layer network, it stores the target data in the database of the OLT's CDN (i.e., database injection). Then, the OLT determines whether the data needs to be further distributed downward (i.e., determines whether the processing has ended). For the data that does not need to be further distributed downward, the processing will stop and it can continue to be stored in the CDN's database. If the target data needs to be further distributed downward, that is, the data is the target data to be forwarded, the OLT can determine whether the target data to be forwarded meets the conditions for delayed forwarding based on the data type of the target data to be forwarded. Among them, the data type includes real-time interaction type and non-real-time interaction type. If the data type of the target data to be forwarded is the real-time interaction type, it does not meet the conditions for delayed forwarding and is directly forwarded and waits for subsequent data. If the data type of the target data to be forwarded is the non-real-time interaction type, it meets the conditions for delayed forwarding, and the OLT needs to determine the operating mode of the ONU (i.e., determines whether the target optical network unit is in the low-power consumption mode). Among them, the operating mode of the ONU includes the low-power consumption mode and the non-low-power consumption mode. If the state of the optical network unit is in the non-low-power consumption mode, it is directly forwarded and waits for subsequent data. If the state of the optical network unit is in the low-power consumption mode, the received target data to be forwarded of the non-real-time interaction type is stored in the CDN's database, and data forwarding is performed when the optical network is in the non-low-power consumption mode (i.e., waits for the low-power consumption stage of the target optical network unit to end).

[0061] That is to say, when the OLT receives the data packet from the upper-layer network, it determines whether it meets the conditions for delayed forwarding, that is, whether the data packet is of the non-real-time interaction type. If it meets the conditions for delayed forwarding, it determines whether the ONU is in the low-power consumption mode. If it is in the low-power consumption mode, it is first stored in the OLT's CDN, delayed forwarding, and waits for the low-power consumption mode of the ONU to end before forwarding it to the ONU.

[0062] Moreover, when the OLT receives a data request from the ONU, if there is corresponding target data in the CDN, the request is terminated, and it can be directly sent to the ONU during the period when the ONU is in the non-low-power consumption mode.

[0063] It should be noted that the upper-layer network 201 and the optical line terminal 202 can be deployed in the core network, and the optical network unit 203 can be deployed in the terminal.

[0064] The terminal can be a device such as a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, etc. with transceiver functions. The specific form of the terminal in this application is not specially limited. It can perform human-computer interaction with the user through one or more ways such as a keyboard, a touchpad, a touch screen, a remote control, voice interaction, or a handwriting device.

[0065] The core network element can include various network functions, such as access and mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF), unified data management (UDM), location management function (LMF), etc.

[0066] After introducing the application scenarios and implementation environments of the embodiments of this application, the energy-saving method for the optical line terminal provided by the embodiments of this application will be introduced in detail below in combination with the above implementation environments.

[0067] The methods in the following embodiments can all be implemented in the above application scenarios and implementation environments. The embodiments of this application will be specifically described below in combination with the accompanying drawings of the specification.

[0068] Figure 5 It is a schematic flowchart of an energy-saving method for an optical line terminal provided by an embodiment of this application. As Figure 5 shown, the method may include: S501 - S504.

[0069] S501. Obtain the data type of the target data to be forwarded.

[0070] Among them, the target data to be forwarded is the target data sent by the upper-layer network to the optical network unit, and the data type includes real-time interaction type and non-real-time interaction type.

[0071] As a possible implementation manner, the optical line terminal may receive the target data to be forwarded sent by the upper-layer network to the optical network unit and determine the target type of the target data to be forwarded.

[0072] It should be noted that in the embodiments of this application, a database of the content delivery network is deployed in the optical line terminal, and the database of the content delivery network is used to store the target data.

[0073] S502. Determine whether the data type of the target data to be forwarded is the non-real-time interaction type requested by the optical network unit.

[0074] In some embodiments, if it is determined that the data type of the target data to be forwarded is the real-time interaction type requested by the optical network unit, the optical line terminal may send the target data to be forwarded to the optical network unit.

[0075] That is to say, when the data type of the target data to be forwarded is a real-time interaction type, the optical line terminal can immediately send the target data to be forwarded of the real-time interaction type to the optical network unit. This method can improve the data transmission efficiency and service quality.

[0076] In some other embodiments, if it is determined that the data type of the target data to be forwarded is a non-real-time interaction type requested by the optical network unit, the optical line terminal may perform S503.

[0077] S503. Determine whether the optical network unit is in a low-power consumption mode.

[0078] It should be noted that the operating modes of the optical network unit include a low-power consumption mode and a non-low-power consumption mode.

[0079] As a possible implementation, the optical line terminal can regularly send operating model query information to the optical network unit. Then, the optical network unit can respond to the operating mode query information and send the operating mode of the optical network unit to the optical line terminal. The optical line terminal can determine whether the optical network unit is in a low-power consumption mode according to the received operating mode of the optical network unit.

[0080] In some embodiments, if it is determined that the optical network unit is in a low-power consumption mode, the optical line terminal may perform S504.

[0081] S504. Stop sending the target data to be forwarded to the optical network unit and store the target data to be forwarded in the database of the content delivery network.

[0082] That is to say, when the optical network unit is in a low-power consumption mode, the optical line terminal can temporarily store the target data to be forwarded in the database of the content delivery network for subsequent transmission in a non-low-power consumption mode. This method can avoid frequently waking up the optical network unit, extend the sleep time of the optical network unit, and thus achieve an energy-saving effect.

[0083] The technical solutions provided by the above embodiments at least bring the following beneficial effects: The optical line terminal can receive the target data to be forwarded sent by the upper-layer network to the optical network unit and determine the data type of the target data to be forwarded. If the data type of the target data to be forwarded belongs to the real-time interaction type, the optical line terminal will judge the current operating state of the optical network unit, and when the optical network unit is in the low-power consumption mode, temporarily store the target data to be forwarded in the database of the content delivery network. In this way, for data with low real-time requirements, the optical line terminal can temporarily store the data in the database of the content delivery network when the optical network unit is in the low-power consumption mode, reducing the number of times the optical network unit is awakened, thereby realizing the energy-saving function of the optical line terminal during the data forwarding process. Moreover, by temporarily storing the data in the database of the content delivery network, the data transmission delay or retransmission problem caused by the low-power consumption state of the optical network unit can be reduced.

[0084] In some embodiments, after determining that the optical network unit is in the low-power consumption mode and the optical line terminal temporarily stores the target data to be forwarded in the database of the content delivery network (i.e., S504), if the optical network unit switches from the low-power consumption mode to the non-low-power consumption mode, the optical line terminal can send the target data to be forwarded stored in the database of the content delivery network to the optical network unit.

[0085] It should be noted that the embodiments of the present application do not limit the manner in which the optical line terminal transmits the target data to be forwarded to the optical network unit. For example, the optical line terminal can use the broadcast method to send the target data to the optical network unit. For another example, the optical line terminal can use the multicast method to send the data packet to the optical network unit. For still another example, the optical line terminal can use the unicast method to send the data packet to the optical network unit.

[0086] As a possible implementation manner, in the case where the optical network unit switches from the low-power consumption mode to the non-low-power consumption mode, the optical line terminal can send all the target data to be forwarded stored in the database of the content delivery network to the optical network unit.

[0087] It can be understood that when the optical network unit is in the low-power consumption mode and the optical line terminal receives multiple non-real-time interaction type target data to be forwarded requested by the optical network unit again, the optical network unit will temporarily store all the target data to be forwarded in the database of the content delivery network. Once the optical network unit switches from the low-power consumption mode to the non-low-power consumption mode, the optical line terminal can send out all the target data to be forwarded temporarily stored in the database of the content delivery network. In this way, by combining the transmission of real-time and non-real-time data packets, the data volume of a single transmission can be increased, making full use of each wake-up opportunity, and avoiding energy waste caused by waking up the optical network unit multiple times due to a small amount of data, thereby realizing the energy-saving function of the optical line terminal during the data forwarding process.

[0088] In some embodiments, the optical line terminal may receive target data sent by the upper-layer network and manage the target data according to the recipient of the target data.

[0089] It should be noted that, in the embodiments of the present application, the recipient of the target data may be an optical network unit, or the recipient of the target data may be a content delivery network.

[0090] As a possible implementation, when the recipient of the target data is an optical network unit, the optical line terminal may use the target data as the target data to be forwarded and execute the embodiments of S501-S504 above.

[0091] As another possible implementation, when the recipient of the target data is a content delivery network, the optical line terminal may store the target data in the database of the content delivery network.

[0092] That is to say, after receiving the target data from the upper-layer network, the optical line terminal may send the target data to be forwarded to the optical network unit. At the same time, after receiving the target data from the upper-layer network, the optical line terminal may also send the target data that does not need to be forwarded to the content delivery network and store the target data in the database of the content delivery network. This method can pre-store the target data in the content delivery network database to achieve pre-caching of the data.

[0093] As a possible implementation, the optical line terminal may predict the data that the user may need to download based on the user's access history and preferences, as well as the frequency of data access, and pre-store the data in the content delivery network database during the idle period of the network to achieve pre-caching of the data. This can improve the user experience without increasing the network load.

[0094] It should be noted that the pre-caching of data can be used in various scenarios. For example, during video on demand, the optical line terminal may pre-cache popular movie or TV drama clips. For another example, the optical line terminal may download course materials or teaching videos in advance on an educational platform. For another example, during disaster warnings, the optical line terminal may pre-store key information to achieve early push of key information to user devices.

[0095] In some embodiments, the target data is stored in the content delivery network database. The optical line terminal may receive a data request message sent by the optical network unit and request the first data according to the data request message. When there is the same target data as the first data in the database of the content delivery network, the optical line terminal may send the same target data as the first data to the optical network unit through the content delivery network.

[0096] As a possible implementation, target data is pre-stored in the database of the content distribution network in the optical line terminal. The optical line terminal can determine the target data identical to the first data from the target data based on the first data requested in the data request message, and send the target data identical to the first data to the optical network unit through the content distribution network.

[0097] That is to say, by pre-storing the target data in the content distribution network database, the target data can be quickly located and transmitted according to the data request message sent by the optical network unit, enabling the optical line terminal to significantly improve the response efficiency and thus optimize the user experience.

[0098] It should be noted that an optical line terminal can send the target data to one optical network unit, or an optical line terminal can also send the target data to multiple optical network units.

[0099] As a possible implementation, when an optical line terminal can send the target data to multiple optical network units, the optical line terminal can pre-store a preset threshold. The optical line terminal can compare the number of optical network units in the non-low power consumption mode with the preset threshold. When the number of optical network units in the non-low power consumption mode is greater than the preset threshold, the optical line terminal can wake up the optical network units in the low power consumption mode for data transmission.

[0100] It should be noted that during the process of the optical line terminal waking up the optical network unit, the optical line terminal can use the low power consumption signaling channel to send the wake-up signal and accurately wake up the optical network unit according to the MAC address (a hardware address that uniquely identifies a network device) or other identifiers of the optical network unit.

[0101] Exemplarily, if the optical line terminal needs to send data to 100 optical network units, and if the currently awakened optical network units are 85 and the preset threshold is 80, the optical line terminal can immediately send wake-up signals to the 15 optical network units in the sleep state to wake up all the optical network units for data transmission.

[0102] Similarly, in combination with the above example, if the currently awakened optical network units are 75, the optical line terminal continues to wait for the end of the sleep phase of the 15 optical network units in the sleep state.

[0103] That is to say, when multiple optical network units need to receive data from the optical line terminal, the optical line terminal can obtain the operating status of each current optical network unit. When the number of optical network units in the wake-up state is greater than a preset threshold, the optical line terminal will not wait for the sleep phase of the remaining few optical network units in the sleep state to end, but will immediately wake up the optical network units in the sleep state for data transmission. In this way, while meeting the needs of most optical network units, the waiting time can be reduced and the data distribution efficiency can be improved.

[0104] In some other embodiments, when there is no target data identical to the first data in the database of the content distribution network, the optical line terminal may send a data request message to the upper-layer network.

[0105] As a possible implementation, the optical line terminal may receive a data request message sent by the optical network unit to request the first data. When there is no target data identical to the first data in the content distribution network database of the optical line terminal, the optical line terminal may send the data request message to the upper-layer network. The upper-layer network may search for the corresponding target data according to the data request message and send the target data as the target data to be forwarded to the optical line terminal. The optical line terminal may send the target data to the optical network unit according to the data type and the operating mode of the optical network unit.

[0106] It can be understood that when the target data in the content distribution network database cannot meet the user's needs, by sending a data request message to the upper-layer network, the OLT can obtain the target data from a wider resource pool to provide a complete data transmission service.

[0107] The above mainly introduces the solution provided by the embodiments of the present application from the perspective of computer devices. It can be understood that in order for a computer device to implement the above functions, it includes the corresponding hardware structure and / or software module for executing each function.

Whether a certain function is executed in the way of hardware or computer software driving the hardware depends on the specific application and design constraints of the technical solution. Professional technicians can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0108] The embodiment of the present application further provides an energy-saving device for an optical line terminal.

[0111] The acquisition module 601 is used to acquire the data type of the target data to be forwarded. The target data to be forwarded is the target data sent by the upper-layer network to the optical network unit. When the data type of the target data to be forwarded is a non-real-time interaction type requested by the optical network unit and the optical network unit is in a low energy consumption mode, the processing module 602 is used to stop sending the target data to be forwarded to the optical network unit and store the target data to be forwarded in the database of the content distribution network.
