Description

Background Art

[0002] With the development of communication technology, the use of PON (Passive Optical Network) technology is becoming more and more widespread. In a PON network, it can include an OLT (Optical Line Terminal) installed in a central control station and at least one ONU (Optical Network Unit) installed in a user's location. When an ONU needs to transmit data in the upstream direction, the PON network needs to allocate corresponding upstream time slot resources to the ONU.

[0003] In the related art, when an ONU needs to transmit data in the upstream direction, the PON network can randomly allocate corresponding upstream time slot resources to the ONU after the ONU goes online, so that the ONU can transmit the related data.

[0004] However, the related art randomly allocates uplink time slot resources to the ONU, which may cause the fixed time slot resources of other online ONUs to be occupied, resulting in insufficient time slots for other online ONUs to send related uplink data in the same frame. Therefore, the uplink time slot resource allocation method provided by the related art will cause a large delay and jitter in the uplink data transmission of other online ONUs, thereby reducing the reliability of uplink data transmission in the PON network.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] The present disclosure provides an uplink time slot resource allocation method, device, electronic device and storage medium, which at least to a certain extent overcome the problem that related technologies may cause large delay and jitter in uplink data transmission of ONU, thereby reducing the reliability of uplink data transmission in PON network.

These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0049] Figure 1 A schematic diagram showing an implementation environment of the uplink time slot resource allocation method that can be applied to the embodiment of the present disclosure is shown.

[0050] like Figure 1As shown, the implementation environment of the uplink time slot resource allocation method may include a controller 101, an OLT 102, and a first ONU 103. The OLT 102 may communicate with the controller 101 and the first ONU 103 respectively.

[0051] The OLT 102 may include at least one PON port, each PON port may communicate with at least one ONU, and the first ONU 103 may be one of the at least one ONU. The controller 101 may allocate corresponding uplink time slot resources to the first ONU 103 through the uplink time slot resource allocation method provided in the embodiment of the present disclosure, so that the first ONU 103 may transmit data to the OLT 102 through the corresponding uplink time slot resources, thereby enabling the first ONU 103 to communicate with the OLT 102.

[0052] In an exemplary embodiment, the first ONU 103 may use time division multiple access technology to send data in the upstream direction of the OUL 102. The time division multiple access technology can divide time into periodic frames, and each frame is further divided into a number of time slots. Under the conditions of meeting timing and synchronization, the OUL 102 can receive the data sent by each ONU in each time slot.

Optionally, the server may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The terminal device may be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto.

[0054] Those skilled in the art will know that Figure 1 The number of controllers 101, OLT 102 and first ONU 103 is only for illustration, and any number of controllers 101 and OLT 102 may be provided according to actual needs, and one or more other ONUs may be provided except the first ONU 103. The embodiments of the present disclosure are not limited to this.

[0055] The present exemplary implementation is described in detail below with reference to the accompanying drawings and embodiments.

[0056] Firstly, an uplink time slot resource allocation method is provided in an embodiment of the present disclosure. The method can be executed by any electronic device with computing and processing capabilities.

[0057] Figure 2 A flow chart of an uplink time slot resource allocation method in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the uplink time slot resource allocation method provided in the embodiment of the present disclosure includes the following steps S202 to S206.

[0058] S202, obtaining pre-configured time slot resources of the first ONU, wherein the pre-configured time slot resources of the first ONU are time slot resources pre-configured for the first ONU from the uplink time slot resources to be allocated, and the pre-configured time slot resources include: a first pre-configured time slot resource of a registration window service type and a second pre-configured time slot resource of a data transmission service type.

[0059] For example, in a PON network, an OLT (Optical Line Terminal) installed in a central control station and at least one ONU (Optical Network Unit) installed in a user's location may be included. The direction in which the ONU sends data to the OLT is the uplink direction. The OLT may include at least one PON port, and any PON port may include at least one time slot resource.

[0060] The PON port may include multiple frames, each frame may be 125μs (microsecond), and each frame may include multiple time slots, each time slot may correspond to a time slot resource. The embodiment of the present disclosure does not limit the length of the time slot. For example, the length of any time slot may be 25μs, or may be 50μs.

[0061] The disclosed embodiments do not limit the uplink time slot resource to be allocated. Exemplarily, the time slots included in the uplink time slot resource to be allocated can all be empty time slots of currently unallocated services. In some embodiments, when a certain ONA needs to transmit data to the OLT, it is necessary to allocate corresponding uplink time slot resources to the ONU. When another ONA needs to send data to the OLT, the other ONA needs to transmit uplink data through the currently unallocated uplink time slot resource. Therefore, the above-mentioned two ONUs will not interfere with each other when transmitting data in the uplink direction respectively.

[0062] In some embodiments, before obtaining the pre-configured time slot resources of the first ONU, the uplink time slot resource allocation method provided by the embodiments of the present disclosure may also include: obtaining network capacity expansion demand data and / or registration windowing demand data; determining the type and quantity of services that need to pre-configure time slot resources based on the network capacity expansion demand data and / or registration windowing demand data, and the services that need to pre-configure time slot resources include the registration windowing service of the first ONU and the data transmission service of the first ONU; pre-configuring the uplink time slot resources to be allocated based on the type and quantity of services that need to pre-configure time slot resources to obtain the pre-configured time slot resources of the first ONU.

[0063] The embodiments of the present disclosure do not limit the method for obtaining the network capacity expansion demand data and / or the registration window opening demand data. The method for obtaining the network capacity expansion demand data and / or the registration window opening demand data can be determined by the application scenario. For example, in an industrial environment, the network capacity expansion demand data and the registration window opening demand data can be obtained through feedback from operation and maintenance personnel or a production management system.

[0064] In a possible implementation, there are three ONUs that are not online and need to transmit corresponding data through uplink time slot resources, and there is one ONU that is online and needs to transmit corresponding data through uplink time slot resources. Therefore, the network expansion requirement data indicates that corresponding pre-configuration is required for the four ONUs, and the registration windowing requirement data indicates that time slot resources used for registration windowing need to be pre-configured for the three ONUs. Therefore, the type and number of services that need to pre-configure time slot resources can be determined based on the above-mentioned network expansion requirement data and registration windowing requirement data. At this time, the services that need to pre-configure time slot resources include data transmission services and registration windowing services, wherein the number of data transmission services is 4, and the number of registration windowing services is 3. It should be noted that the first ONU can be any one of the three ONUs that are not online.

[0065] In some embodiments, the first ONU is an ONU that is not online, and the first ONU needs to transmit data in the upstream direction once every 2 seconds after successfully going online. Therefore, the first pre-configured time slot resource of the first ONU and the second pre-configured time slot resource of the first ONU can be pre-configured for the first ONU in the current upstream time slot resource to be allocated, the first pre-configured time slot resource of the first ONU is used for the first ONU to register online, and the second pre-configured time slot resource of the first ONU can be used for the first ONU to transmit data in the upstream direction once every 2 seconds.

[0066] In some embodiments, the uplink time slot resources to be allocated are pre-configured according to the type and quantity of the services for which the time slot resources need to be pre-configured, and the pre-configured time slot resources of the first ONU are obtained, including: allocating corresponding registration and authentication resources to the first pre-configured time slot resources in the pre-configured time slot resources of the first ONU, and the registration and authentication resources are used for the first ONU to register and go online.

[0067] In an exemplary embodiment, the registration and authentication resources corresponding to different ONU registration windows may be different. For example, one ONU needs to transmit data in the upstream direction once every 3 seconds, while another ONU needs to transmit data in the upstream direction once every 1 second. Then the registration and authentication resources required by the above two ONUs may be different.

[0068] It should be noted that, when the first ONU successfully goes online through the first pre-configured time slot resource corresponding to the first ONU, the first pre-configured time slot resource of the first ONU is vacated again, and the first pre-configured time slot resource can be re-pre-configured for registration windowing of other ONUs.

[0069] S204, when it is monitored that the first ONU is online, a first pre-configured time slot resource is allocated to the first ONU, and the first pre-configured time slot resource is used for the first ONU to register and go online.

[0070] In some embodiments, the first ONU needs to register and go online before transmitting data in the upstream direction. When the controller for controlling the OLT detects that the first ONU needs to go online, the first preconfigured time slot resource preconfigured for the first ONU can be allocated to the first ONU to register and go online.

[0071] Exemplarily, the first pre-configured time slot resource of the first ONU includes a registration authentication resource for the first ONU to register and go online. In addition, the embodiment of the present disclosure does not limit the step of the first ONU registering and going online through the first pre-configured time slot resource of the first ONU.

[0072] S206, in response to the condition that the first ONU successfully registers and goes online, allocate a second pre-configured time slot resource to the first ONU, where the second pre-configured time slot resource is used for the first ONU to transmit relevant data.

[0073] In some embodiments, when pre-configuring the uplink time slot resources, multiple ONUs to be online may be configured at the same time. In addition, multiple ONUs to be online need to be in the uplink direction. Therefore, obtaining the pre-configured time slot resources of the first ONU includes: obtaining the pre-configured time slot resources of multiple ONUs including the pre-configured time slot resources of the first ONU, and the pre-configured time slot resources of the multiple ONUs include multiple second pre-configured time slot resources with different data transmission time intervals. In this case, allocating the second pre-configured time slot resources to the first ONU includes: determining the data transmission time interval of the first ONU; and allocating the second pre-configured time slot resources corresponding to the data transmission time interval to the first ONU according to the data transmission time interval of the first ONU.

[0074] In an exemplary embodiment, it is assumed that uplink time slots are preconfigured for three ONUs with different data transmission time intervals, and the three ONUs with different data transmission time intervals include a first ONU. Therefore, after the first ONU goes online, it is necessary to first determine the data transmission time interval of the first ONU. Afterwards, a second preconfigured time slot resource corresponding to the data transmission time interval of the first ONU is determined in the second preconfigured time slot resources with different data transmission time intervals corresponding to the above three ONUs.

[0075] In a possible implementation, the method for allocating uplink time slot resources provided by the embodiment of the present disclosure may also include: in response to the condition that the first ONU successfully registers and goes online, releasing the first pre-configured time slot resources of the first ONU, and the first pre-configured time slot resources of the first ONU are used for other ONUs that go online after the first ONU to register and go online or transmit related data.

[0076] Exemplarily, after the first ONU successfully goes online, the second ONU is to be online, then the first pre-configured time slot resource for the first ONU to register online can be released for the second ONU to register online. Alternatively, the first pre-configured time slot resource for the first ONU to register online can be used for the second ONU to transmit related data. It should be noted that when the first pre-configured time slot resource for the first ONU to register online is released and used for the second ONU to register online, it is necessary to reallocate the registration authentication resource corresponding to the second ONU for the first pre-configured time slot resource for the first ONU to register online.

[0077] In some embodiments, the uplink time slot resource allocation method provided by the embodiment of the present disclosure may also include: when the second ONU needs to go online, determining whether the currently unallocated first preconfigured time slot resources and the second preconfigured time slot resources meet the business needs of the second ONU, the second ONU being an ONU other than the first ONU; if the business needs of the second ONU are met, allocating the first preconfigured time slot resources of the registered windowing service type to the second ONU; if the needs of the second ONU are not met, refusing the second ONU to go online at the PON port where the current first preconfigured time slot resources and the second preconfigured time slot resources are located.

[0078] Exemplarily, when the second ONU goes online, it is necessary to allocate the corresponding first pre-configured time slot resource for the second ONU to register and go online. And after the second ONU successfully goes online, it is also necessary to allocate the corresponding second pre-configured time slot resource for the second ONU to transmit data. However, the number of time slots included in each PON port is limited. Therefore, when the second ONU needs to be capped, it is determined whether the first pre-configured time slot resource and the second pre-configured time slot resource that are not currently allocated can meet the service requirements of the second ONU.

[0079] In a possible implementation, the second ONU needs to send data to the upstream direction once every 3 seconds after going online, but the currently unallocated second pre-configured time slot resources can only support the second ONU to send data once every 5 seconds, so the currently unallocated second time slot resources cannot meet the service requirements of the second ONU. Therefore, the second ONU cannot go online at the PON port where the current first pre-configured time slot resources and the second pre-configured time slot resources are located.

[0080] In another possible implementation, the second ONU needs to send data to the upstream direction once every 3 seconds after going online, and the currently unallocated first preconfigured time slot resources can support the second ONU to register and open the window, and the currently unallocated second preconfigured time slot resources can support the second ONU to perform data transmission once every 3 seconds. Therefore, the currently unallocated first preconfigured time slot resources and the second preconfigured time slot resources meet the service requirements of the second ONU, and the corresponding first preconfigured familiar resources can be allocated to the second ONU to enable the second ONU to go online.

[0081] The method provided by the embodiment of the present disclosure obtains the pre-configured time slot resources pre-configured for the first ONU from the uplink time slot resources to be allocated, and the pre-configured resources of the first ONU include the first pre-configured time slot resources for the first ONU to register and go online and the second pre-configured time slot resources for the first ONU to transmit related data. Therefore, the embodiment of the present disclosure can ensure that the first ONU will not occupy the fixed time slots of the uplink transmission direction of other online ONUs when registering and transmitting data, avoiding the generation of large delays and jitters for the uplink data transmission of the online ONUs in the PON network, thereby improving the certainty and reliability of the uplink data transmission of the PON network.

[0082] In some embodiments, a process of uplink time slot resource allocation may be as follows: Figure 3 As shown. For example, Figure 3 The three ONUs shown in the figure are in the stage of sending uplink data normally, that is, ONU (optical network unit) 1, ONU 2 and ONU 3 are sending uplink data respectively. When no new registration window is generated, the three ONUs carrying different services can occupy different uplink time slot resources in N-1 frame, N frame and N+1 frame to transmit data in the uplink direction. At this time, the delay jitter generated by ONU 1, ONU 2 and ONU 3 transmitting data is relatively stable.

[0083] At this time, the currently allocated time slot resources can be pre-configured according to the network expansion demand data and / or the registration window opening demand data. Figure 3 As shown, a plurality of currently unallocated time slot resources are pre-configured in the N-1 frame, the N frame, and the N+1 frame.

[0084] When the OLT inserts the registration window, Figure 3 As shown in the figure, when ONU 4 needs to go online, the OLT directly uses a first pre-configured time slot resource in the N+1th frame to register and open windows for ONU 4, and will not occupy the time slot resources used by ONU 1, ONU 2 and ONU 3 to perform corresponding services. Therefore, the registration and windowing of ONU 4 will not affect the delay jitter generated by the data transmission of ONU 1, ONU 2 and ONU 3.

[0085] Afterwards, when ONU 4 successfully goes online, ONU 4 can transmit uplink data through the second preconfigured time slot resources preconfigured for the data transmission service corresponding to ONU 4. Therefore, ONU 4 performs related data transmission without affecting the delay jitter generated by data transmission of ONU 1, ONU 2 and ONU 3.

[0086] In an exemplary embodiment, an uplink time slot resource allocation system may be as follows: Figure 4As shown. Figure 4 In the embodiment, the uplink time slot resource allocation system may include a network resource planning module, an ONU registration and authentication module, and an uplink time slot resource allocation module.

[0087] In some embodiments, the network resource planning module can be used to determine the type and quantity of services that require pre-configured time slot resources based on network capacity expansion demand data and / or registration window demand data fed back by operation and maintenance personnel or a production management system.

[0088] The ONU registration and authentication module can be used to pre-configure corresponding registration and authentication resources according to the type of service that needs to pre-configure time slot resources determined by the network resource planning module.

[0089] The uplink time slot resource allocation module can be used to pre-configure currently unallocated empty time slots according to the type and quantity of services that need to pre-configure time slot resources determined by the above network resource planning module, and obtain corresponding first pre-configured time slot resources and second pre-configured time slot resources. Pre-configuring the corresponding first pre-configured time slot resources and second pre-configured time slot resources includes pre-configuring the corresponding number and sequence of time slots for each service.

[0090] The ONU registration and authentication module can be used to determine the service type corresponding to the first ONU when the first ONU needs to go online, and allocate the corresponding first pre-configured time slot resources to the first ONU. And after the first ONU goes online, the corresponding second pre-configured time slot resources are allocated to the first ONU. And, when a second ONU needs to go online later, the ONU registration and authentication module can be used to determine whether the currently unallocated first pre-configured time slot resources and the second pre-configured time slot resources meet the service requirements of the second ONU.
