[0073] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0074] Figure 1 This is a schematic diagram illustrating an application scenario of a service transmission method provided in an embodiment of this application. For example... Figure 1 As shown, this scenario includes an Optical Line Terminal (OLT) 100, an Optical Network Unit (ONU) 200, and an Optical Distribution Network (ODN) 300. The ODN 300 is located between the OLT 100 and the ONUs 200, connecting one OLT 100 and multiple ONUs 200 to provide bidirectional transmission of optical signals. The components used in the ODN 300 include optical fibers, All of these are passive optical devices. The OLT (Optical Line Terminal) is the operator-side equipment, responsible for allocating upper-layer service network data to users. The ONU (Optical Network Unit) is the user-side equipment, responsible for receiving data sent by the OLT and directly providing services to users. The network composed of OLT 100, ONU 200, and ODN 300 can be called a Passive Optical Network (PON). In a PON network, downlink data is sent via broadcast. Each ONU 200 receives its own data based on the downlink data identifier and discards data from other ONUs. Uplink data from each ONU 200 is sent in a time-division multiplexing manner. The transmission time and length of each ONU 200 are centrally controlled by the OLT 100, enabling shared access for multiple ONUs. A PON network is a pure media network, avoiding electromagnetic interference and lightning strikes from external devices, reducing the failure rate of lines and external equipment, improving system reliability, and saving maintenance costs. Depending on the technology used, PON can be divided into ATM Passive Optical Network (APON), which is a passive optical network based on ATM technology; Ethernet Passive Optical Network (EPON), which is a passive optical network based on Ethernet; and Gigabit-Capable PON (GPON), etc. It should be noted that the service transmission method provided in this application embodiment can be applied to GPON networks.

[0075] In traditional technologies, PON networks create different service transmission containers (tcont) for different service requirements. PON, combined with Dynamic Bandwidth Allocation (DBA) templates, allocates bandwidth to all tconts within a calculation period T. Figure 2 The uplink transmission window shown is used for data transmission. Figure 2 In the diagram, uplink transmission window A1 is the uplink transmission window corresponding to optical network unit A, uplink transmission windows B1 and B2 are the uplink transmission windows corresponding to optical network unit B, and uplink transmission windows C1 and C2 are the uplink transmission windows corresponding to optical network unit C. Currently, the existing ITU-T for ITU Telecommunication Standardization Sector PON (ITU-T PON) protocol stipulates that the ONU registration and activation state machine cycle in a PON network require the OLT to provide different static windows, such as... Figure 2 The example shown is a static window. However, in this static window, only offline ONUs and designated ranging ONUs can report the corresponding signaling messages; the uplink transmission windows for other normal service transmissions are suppressed. Figure 2 In the example shown, uplink transmission windows A1, B2, and C2 will all be suppressed. Data transmission in uplink transmission windows A1, B2, and C2 will be affected by the static window. Typically, the duration of the uplink transmission window is similar to the length of the static window. Therefore, this will result in a large delay in the data transmission of ONUA, ONUB, and ONUC.

[0076] Based on the above-mentioned traditional technology, this application provides a service transmission method. By sorting the uplink transmission windows of ONU services and specifying the starting point of the static window on the transmission resource, the service is transmitted on the transmission resource through the burst window after the service sorting, so as to minimize the impact of the static window on the transmitted service, thereby reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.

[0077] It should be noted that the beneficial effects or technical problems solved by the embodiments of this application are not limited to this one, but may also be other implicit or related problems. For details, please refer to the description of the embodiments below.

[0078] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0079] In one embodiment, such as Figure 3 As shown, a service transmission method is provided, which is applied to... Figure 1 Taking the optical network unit in the image as an example, the following steps are included:

[0080] S201, sort the uplink transmission windows of the ONU's services.

[0081] Among them, the Optical Network Unit (ONU), commonly known as an "optical modem", is a device or functional block in a Passive Optical Network (PON) that provides a user-side interface and is connected to the Optical Distribution Network (ODN). It is responsible for receiving data sent by the Optical Line Terminal (OLT) and providing services to users.

[0082] Typically, in a PON, different service transmission containers (tcont) are created for different service requirements. PON can combine the Dynamic Bandwidth Allocation (DBA) template to allocate uplink transmission windows for all tconts within a calculation period T for data transmission. In other words, in this embodiment, the uplink transmission window of a service refers to the uplink transmission window for transmitting the service. In this embodiment, the ONU may have one or more services, and each service corresponds to an uplink transmission window.

[0083] In some service transmission scenarios, such as Augmented Reality (AR) / Virtual Reality (VR) and industrial control, there are deterministic requirements for service latency, demanding low latency transmission. These services can be referred to as low-latency services. It is understood that, in this embodiment, optionally, when the service is a low-latency service, the uplink transmission window for low-latency services can be prioritized before the uplink transmission windows of other services to ensure timely transmission and reduce transmission latency. When the service does not have low-latency requirements, the uplink transmission window for other services can be prioritized after the burst window of low-latency services to ensure timely transmission and reduce transmission latency. Optionally, the service in this embodiment can be the low-latency service mentioned above, or it can be a service with no latency requirements, or it can be a service with special transmission requirements. This embodiment does not impose any restrictions here.

[0084] As an optional implementation, when the service is a low-latency service and there are multiple services, when sorting the uplink transmission windows of the services, the uplink transmission windows of the services can be prioritized and placed before the uplink transmission windows of other services. Furthermore, the uplink transmission windows with higher priority can be placed at the beginning of the list. For example, let uplink transmission window A1 be the uplink transmission window corresponding to ONUA in the PON network, uplink transmission windows B1 and B2 be the uplink transmission windows corresponding to ONUB in the PON network, and uplink transmission windows C1 and C2 be the uplink transmission windows corresponding to ONUC in the PON network. Here, uplink transmission windows A1, B1, and C2 are examples of the uplink transmission windows of the services in this embodiment. If the priority of uplink transmission windows A1, B1, and C2 is B1>C2>A1, then the sorting result obtained by sorting the uplink transmission windows of the services according to the priority of each uplink window can be as follows: Figure 4 As shown.

[0085] As another optional implementation, priority order can be set for all services. For example, high priority can be set for video data, AR or VR data, medium priority for audio data, and low priority for SMS, email and other data. The uplink transmission windows of the services can be sorted according to the priority order of each service.

[0086] S202, Transmit the ordered services on the transmission resources; the transmission resources include a static window with a specified starting point.

[0087] In practical application scenarios, there may be cases where ONUs go offline. Therefore, it is necessary to re-register and reactivate offline ONUs. In this embodiment, the static window on the transmission resource is the static window provided by the OLT in the ONU registration and activation state machine loop. Typically, in this static window, only offline ONUs and designated ranging ONUs can report the corresponding signaling messages, while the uplink transmission windows of other normal service transmissions are suppressed.

[0088] In this embodiment, the starting point of the static window is a specified starting point. It should be noted that the purpose of specifying the starting point of the static window in this embodiment is to minimize the impact of the static window on the ONU's service transmission. As an optional implementation, the specified starting point of the static window can be determined based on the number of services, as long as the impact of the static window on the ONU's service transmission is minimized. Continuing with the example where uplink transmission windows A1, B1, and C2 are all uplink transmission windows for services in this embodiment, the specified starting point of the static window can be as follows: Figure 5 As shown, after the uplink transmission windows A1, B1, C2, or, the specified starting point of the static window can also be as follows. Figure 6 As shown, any point in the uplink transmission window A1 should be such that the impact of the static window on the ONU's service transmission is reduced.

[0089] In this embodiment, when the ONU transmits services to the OLT, it can transmit the sorted services on the transmission resources according to the order of the uplink transmission windows of the services. For example, taking the burst windows of the services as the uplink transmission windows A1, B1, B2, C1, and C2, if the order of the burst windows of the sorted services is B1, A1, C1, B2, and C2, then the ONU can transmit the sorted services on the transmission resources according to this order.

[0090] In the above-described service transmission method, by sorting the uplink transmission windows of the ONU's services, the ONU can transmit services on the transmission resources according to the order of the uplink transmission windows. Furthermore, the starting point of the static window on the transmission resources is specified. This allows consideration of the impact of the static window on service transmission when specifying the starting point of the static window. The starting point of the static window can be specified as a point that minimizes the impact of the static window on the transmitted services. This ensures that when transmitting the sorted services on the transmission resources, the impact of the static window on the transmitted services can be minimized, thereby reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.

[0091] In this embodiment, the specified position of the starting point of the static window will be described in detail. In one embodiment, the specified starting point may be related to the uplink transmission window of the low-latency service in the ONU's services.

[0092] As described in the above embodiments, the purpose of specifying the starting point of the static window is to minimize the impact of the static window on the ONU's service transmission. Therefore, the specified starting point of the static window is related to the uplink transmission window of the low-latency service in the ONU's services, ensuring that the impact of the static window on service transmission is minimized. Optionally, the starting point of the static window can be related to the number of uplink transmission windows for low-latency services, the duration of the uplink transmission windows for low-latency services, or both the number and duration of the uplink transmission windows for low-latency services.

[0093] Assuming the service in this embodiment is a series of low-latency services, as an optional implementation, any point after the uplink transmission window of all low-latency services can be determined as the starting point of the static window. Continuing with the example where uplink transmission windows A1, B1, and C2 are all uplink transmission windows for low-latency services in this embodiment, the specified starting point of the static window can be... Figure 7 The example given means that the specified starting point of the static window is later than the uplink transmission window of the low-latency service; or, as another optional implementation, the starting point of the static window can be specified as any point within the last burst window of all low-latency service burst windows, that is, the specified starting point of the static window can be... Figure 8 The example location. However, it's understandable that when the specified starting point of a static window is... Figure 7 In the example positions, static windows have the least impact on service transmission; therefore, in the two examples above, Figure 7 The example static window specifies a preferred starting point.

[0094] In this embodiment, since the specified starting point of the static window is related to the uplink transmission window of the low-latency service in the service, the starting point of the static window can be specified as the point that can minimize the impact of the static window on the transmitted service. This allows the static window to minimize the impact on the transmitted service when transmitting the ordered service on the transmission resources, thereby reducing the latency of the ONU's data transmission and improving the service quality of the ONU's uplink transmission.

[0095] In the scenario described above, where a static window's starting point is specified, the starting point can be defined on a unit of one transmission cycle. In one embodiment, the specified starting point can be later than the uplink transmission window of all low-latency services within the transmission cycle.

[0096] In this embodiment, the starting point of the static window can be specified as after the uplink transmission window of all low-latency services within the transmission period, using transmission cycles as the unit. Figure 9 Taking transmission period N as an example, the starting point of the static window within transmission period N can be specified to be later than the uplink transmission window of all low-latency services within that transmission period. That is, the specified starting point of the static window within transmission period N can be, for example... Figure 9 The starting point shown in the example, Figure 9 Uplink transmission windows A1, B2, and C2 in the diagram are all uplink transmission windows corresponding to low-latency services, and are determined by... Figure 9 It can be seen that within the transmission period N, the static window does not affect the uplink transmission windows A1, B2, and C2 of the low-latency service within that transmission period. It only affects the transmission of A1 in the uplink transmission window of the low-latency service in the next transmission period N+1. However, compared with existing technologies, the impact of the static window on service transmission has been minimized, reducing the latency of ONU data transmission.

[0097] In this embodiment, the specified start point of the static window is later than the uplink transmission window of all low-latency services within the transmission cycle. This can reduce the impact of the static window on service transmission within the transmission cycle, thereby minimizing the impact of the static window on transmitted services, and further reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.

[0098] As an optional implementation, this embodiment will describe in detail the process of sorting the uplink transmission windows of the ONU's services. In one embodiment, the above-mentioned S201 may include: sorting the uplink transmission windows of the ONU's services according to a preset sorting logic.

[0099] Optionally, the preset sorting logic in this embodiment can be a sorting logic determined by the priority of services. As an optional implementation, the preset sorting logic can be that the uplink transmission window of the service with higher priority in the ONU's services is arranged earlier, and the uplink transmission window of the service with lower priority in the ONU's services is arranged later, thereby minimizing the impact of static windows on service transmission.

[0100] For example, suppose the ONU includes three services: A, B, and C. The uplink transmission windows corresponding to services A, B, and C are a, b, and c, respectively. If the priority order of these three services is B>C>A, then according to the above sorting logic, the order of the uplink transmission windows of services A, B, and C can be b>c>a.

[0101] In this embodiment, the preset sorting logic can be determined based on the priority of each service. This allows the uplink transmission windows of services to be sorted according to their priorities, which can minimize the impact of static windows on the uplink transmission windows of services when transmitting on transmission resources. This reduces the latency of ONU data transmission and improves the service quality of ONU uplink transmission.

[0102] This embodiment will describe the details of the above sorting logic. In one embodiment, the sorting logic may include a first sorting rule and / or a second sorting rule. The first sorting rule is used to sort the uplink transmission windows of low-latency services and non-low-latency services in the services of the ONU. The second sorting rule is used to sort the uplink transmission windows of each low-latency service.

[0103] Optionally, the sorting logic in this embodiment may include a first sorting rule and / or a second sorting rule. The first sorting rule can be used to sort the uplink transmission windows of low-latency services and non-low-latency services in the ONU's services. Optionally, in this embodiment, the first sorting rule may include adjusting the uplink transmission windows of low-latency services to precede the uplink transmission windows of non-low-latency services. For example, if uplink transmission windows A1, B2, and C2 are the uplink transmission windows of low-latency services, and uplink transmission windows B1 and C1 are the uplink transmission windows of non-low-latency services, then after sorting the uplink transmission windows of low-latency services and non-low-latency services according to the first sorting rule, the sorted order of the uplink transmission windows of low-latency services and non-low-latency services can be as follows: Figure 10 The sorting shown.

[0104] Optionally, the aforementioned second sorting rule can be used to sort the uplink transmission windows of each low-latency service. As an optional implementation, the second sorting rule may include sorting the uplink transmission windows of each low-latency service according to their window length. Optionally, as an optional implementation, the uplink transmission windows of each low-latency service may be sorted in descending order of window length. Alternatively, as another optional implementation, the uplink transmission windows of each low-latency service may be sorted in ascending order of window length. However, it should be noted that... (See also: [link to previous text]). Figure 11 and Figure 12 , Figure 11 This diagram illustrates the sorting results of the uplink transmission windows for each low-latency service, arranged in descending order of window length. Figure 12 To sort the uplink transmission windows of each low-latency service in ascending order of window length, the following diagram illustrates the sorting result of the uplink transmission windows for each low-latency service: Figure 11 and Figure 12 The comparison shows that sorting the uplink transmission windows of each low-latency service in descending order of window length minimizes the number of uplink transmission windows affected by low-latency services. Conversely, sorting them in ascending order of window length will affect the uplink transmission windows of two low-latency services in the next transmission cycle. Therefore, sorting the uplink transmission windows of each low-latency service in descending order of window length is a superior sorting rule, as it minimizes the number of uplink transmission windows affected by low-latency services.

[0105] In this embodiment, the preset sorting logic includes a first sorting rule and / or a second sorting rule. The first sorting rule can sort the uplink transmission windows of low-latency services and the uplink transmission windows of non-low-latency services. The second sorting rule can sort the uplink transmission windows of each low-latency service. This sorting logic considers both the uplink transmission windows of low-latency services and the transmission order of the uplink transmission windows of non-low-latency services. After sorting the uplink transmission windows of the ONU services according to this sorting logic, the uplink transmission windows of the sorted services can further reduce the impact of static windows on the uplink transmission windows of services when transmitting on transmission resources, thereby reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.

[0106] As another optional implementation, this embodiment will describe in detail the process of sorting the uplink transmission windows of the ONU's services. In one embodiment, such as... Figure 13 As shown, the above S201 may include:

[0107] S301, adjust the uplink transmission window of low-latency services in the ONU's services to be before the uplink transmission window of non-low-latency services.

[0108] Optionally, in this embodiment, taking the uplink transmission window for low-latency services as including A1, B2, and C2, and the uplink transmission window for non-low-latency services as including B1 and C1 as an example, according to the sorting rules before adjusting the uplink transmission window for low-latency services to the uplink transmission window for non-low-latency services, the resulting sorting of the uplink transmission windows for low-latency services and non-low-latency services can be: A1>B2>C2>B1>C1.

[0109] S302, sort the uplink transmission windows of each low-latency service in descending order of window length.

[0110] In this embodiment, taking the uplink transmission windows of the low-latency service as A1, B2, and C2, and the uplink transmission windows of the non-low-latency service as B1 and C1 as an example, assuming that the burst windows A1, B2, and C2 are arranged in descending order of window length as B2>C2>A1, then based on the above sorting, the sorting of the uplink transmission windows of the low-latency service and the non-low-latency service can be adjusted to: B2>C2>A1>B1>C1.

[0111] In this embodiment, by adjusting the uplink transmission window of low-latency services to be before the uplink transmission window of non-low-latency services, and then sorting the uplink transmission windows of each low-latency service in descending order of window length, the uplink transmission windows of the sorted services can minimize the impact of static windows on the uplink transmission windows of services when transmitting on transmission resources, thereby reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.

[0112] In one embodiment, a service transmission method is provided, in which the method is applied to Figure 1 Taking the optical line terminal in the middle as an example, the process includes the following steps: receiving the services of the ONU after the uplink transmission window is sorted through the transmission resources; the transmission resources include a static window with a specified starting point.

[0113] Among them, the Optical Network Unit (ONU), commonly known as an "optical modem", is a device or functional block in a Passive Optical Network (PON) that provides a user-side interface and is connected to the Optical Distribution Network (ODN). It is responsible for receiving data sent by the Optical Line Terminal (OLT) and providing services to users.

[0114] Typically, in a PON, different service transmission containers (tcont) are created for different service requirements. PON can combine Dynamic Bandwidth Allocation (DBA) templates to allocate uplink transmission windows for all tconts within a calculation period T for data transmission. In other words, in this embodiment, the uplink transmission window of the ONU's service refers to the uplink transmission window for transmitting the ONU's service. In this embodiment, the service may include one or more services, and each service corresponds to an uplink transmission window.

[0115] In some service transmission scenarios, such as Augmented Reality (AR) / Virtual Reality (VR) and industrial control, there are deterministic requirements for service latency, demanding low latency transmission. These services can be referred to as low-latency services. It is understood that, in this embodiment, optionally, when the service is a low-latency service, the uplink transmission window for low-latency services can be prioritized before the uplink transmission windows of other services to ensure timely transmission and reduce transmission latency. When the service does not have low-latency requirements, the uplink transmission window for other services can be prioritized after the burst window of low-latency services to ensure timely transmission and reduce transmission latency. Optionally, the service in this embodiment can be the low-latency service mentioned above, or it can be a service with no latency requirements, or it can be a service with special transmission requirements. This embodiment does not impose any restrictions here.

[0116] As an optional implementation, when the service is a low-latency service and there are multiple services, when sorting the uplink transmission windows of the services, the uplink transmission windows of the services can be prioritized and placed before the uplink transmission windows of other services. Furthermore, the uplink transmission windows with higher priority can be placed at the beginning of the list. For example, let uplink transmission window A1 be the uplink transmission window corresponding to ONUA in the PON network, uplink transmission windows B1 and B2 be the uplink transmission windows corresponding to ONUB in the PON network, and uplink transmission windows C1 and C2 be the uplink transmission windows corresponding to ONUC in the PON network. Here, uplink transmission windows A1, B1, and C2 are examples of the uplink transmission windows of the services in this embodiment. If the priority of uplink transmission windows A1, B1, and C2 is B1>C2>A1, then the sorting result obtained by sorting the uplink transmission windows of the services according to the priority of each uplink window can be as follows: Figure 14 As shown.

[0117] As another optional implementation, priority order can be set for all services. For example, high priority can be set for video data, AR or VR data, medium priority for audio data, and low priority for SMS, email and other data. The uplink transmission windows of the services can be sorted according to the priority order of each service.

[0118] In practical application scenarios, there may be cases where ONUs go offline. Therefore, it is necessary to re-register and reactivate offline ONUs. In this embodiment, the static window on the transmission resource is the static window provided by the OLT in the ONU registration and activation state machine loop. Typically, in this static window, only offline ONUs and designated ranging ONUs can report the corresponding signaling messages, while the uplink transmission windows of other normal service transmissions are suppressed.

[0119] In this embodiment, the starting point of the static window is a specified starting point. It should be noted that the purpose of specifying the starting point of the static window in this embodiment is to minimize the impact of the static window on the ONU's service transmission. As an optional implementation, the specified starting point of the static window can be determined based on the number of services, as long as the impact of the static window on the ONU's service transmission is minimized. Continuing with the example where uplink transmission windows A1, B1, and C2 are all uplink transmission windows for services in this embodiment, the specified starting point of the static window can be... Figure 15 The specified starting point shown is after the uplink transmission windows A1, B1, and C2, or, alternatively, the static window can also be... Figure 16 As shown, any point in the uplink transmission window A1 should be such that the impact of the static window on the ONU's service transmission is reduced.

[0120] In this embodiment, when the ONU transmits services to the OLT, it can transmit the ordered services on the transmission resources according to the order of the uplink transmission windows of the aforementioned services, and the OLT receives the services through the transmission resources. For example, taking the burst windows of the services as the aforementioned uplink transmission windows A1, B1, B2, C1, C2, if the order of the burst windows of the ordered services is B1, A1, C1, B2, C2, then the ONU can transmit the ordered services on the transmission resources according to this order, and the OLT receives the services through the transmission resources.

[0121] In the above service transmission method, the services received by the OLT through the transmission resources are transmitted after the uplink transmission windows of the ONU's services are sorted. By sorting the uplink transmission windows of the ONU's services, the ONU can transmit services on the transmission resources according to the order of the uplink transmission windows. Furthermore, the starting point of the static window on the transmission resources is specified. In this way, the influence of the static window on service transmission can be considered when specifying the starting point of the static window. The point that can minimize the impact of the static window on the transmitted services can be specified as the starting point of the static window. This allows the impact of the static window on the transmitted services to be minimized when transmitting the sorted services on the transmission resources, thereby reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.

[0122] In this embodiment, the specified position of the starting point of the static window will be described in detail. In one embodiment, the specified starting point may be related to the uplink transmission window of the low-latency service in the ONU's services.

[0123] As described in the above embodiments, the purpose of specifying the starting point of the static window is to minimize the impact of the static window on the ONU's service transmission. Therefore, the specified starting point of the static window is related to the uplink transmission window of the low-latency service in the ONU's services, ensuring that the impact of the static window on service transmission is minimized. Optionally, the starting point of the static window can be related to the number of uplink transmission windows for low-latency services, the duration of the uplink transmission windows for low-latency services, or both the number and duration of the uplink transmission windows for low-latency services.

[0124] Assuming the service in this embodiment is a series of low-latency services, as an optional implementation, any point after the uplink transmission window of all low-latency services can be designated as the starting point of the static window. Continuing with the example where uplink transmission windows A1, B1, and C2 are all uplink transmission windows for low-latency services in this embodiment, the designated starting point of the static window can be later than the uplink transmission window of the low-latency services. Alternatively, as another optional implementation, the starting point of the static window can be designated as any point within the last burst window of all burst windows for low-latency services. However, it is understood that when the designated starting point of the static window is later than the uplink transmission window of the low-latency services, the static window has the least impact on service transmission. Therefore, in the above two examples, designating the starting point of the static window later than the uplink transmission window of the low-latency services is a preferred location for designating the starting point.

[0125] In this embodiment, since the specified starting point of the static window is related to the uplink transmission window of the low-latency service in the service, the starting point of the static window can be specified as the point that can minimize the impact of the static window on the transmitted service. This allows the static window to minimize the impact on the transmitted service when transmitting the ordered service on the transmission resources, thereby reducing the latency of the ONU's data transmission and improving the service quality of the ONU's uplink transmission.

[0126] In the scenario described above, where a static window's starting point is specified, the starting point can be defined on a unit of one transmission cycle. In one embodiment, the specified starting point can be later than the uplink transmission window of all low-latency services within the transmission cycle.

[0127] In this embodiment, the starting point of the static window can be specified as after the uplink transmission window of all low-latency services within the transmission period, using transmission cycles as the unit. Figure 17 Taking transmission period N as an example, the starting point of the static window within transmission period N can be specified to be later than the uplink transmission window of all low-latency services within that transmission period. That is, the specified starting point of the static window within transmission period N can be, for example... Figure 17 The starting point shown in the example, Figure 17 Uplink transmission windows A1, B2, and C2 in the diagram are all uplink transmission windows corresponding to low-latency services, and are determined by... Figure 17 It can be seen that within the transmission period N, the static window does not affect the uplink transmission windows A1, B2, and C2 of the low-latency service within that transmission period. It only affects the transmission of A1 in the uplink transmission window of the low-latency service in the next transmission period N+1. However, compared with existing technologies, the impact of the static window on service transmission has been minimized, reducing the latency of ONU data transmission.

[0128] In this embodiment, the specified start point of the static window is later than the uplink transmission window of all low-latency services within the transmission cycle. This can reduce the impact of the static window on service transmission within the transmission cycle, thereby minimizing the impact of the static window on transmitted services, and further reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.

[0129] As an optional implementation, this embodiment will describe in detail the process of sorting the uplink transmission window of the ONU's services. In one embodiment, the services transmitted on the transmission resources are transmitted after sorting the uplink transmission window of the ONU's services according to a preset sorting logic.

[0130] Optionally, the preset sorting logic in this embodiment can be a sorting logic determined according to the priority of ONU services. As an optional implementation, the preset sorting logic can be that the uplink transmission window of the service with higher priority in the ONU services is arranged earlier, and the uplink transmission window of the service with lower priority in the ONU services is arranged later, so as to minimize the impact of static windows on service transmission.

[0131] For example, suppose the ONU includes three services: A, B, and C. The uplink transmission windows corresponding to services A, B, and C are a, b, and c, respectively. If the priority order of these three services is B>C>A, then according to the above sorting logic, the order of the uplink transmission windows of services A, B, and C can be b>c>a.

[0132] In this embodiment, the preset sorting logic can be determined based on the priority of each service. This allows the uplink transmission windows of services to be sorted according to their priorities, which can minimize the impact of static windows on the uplink transmission windows of services when transmitting on transmission resources. This reduces the latency of ONU data transmission and improves the service quality of ONU uplink transmission.

[0133] This embodiment will describe the details of the above sorting logic. In one embodiment, the sorting logic may include a first sorting rule and / or a second sorting rule. The first sorting rule is used to sort the uplink transmission windows of low-latency services and non-latency services in the service. The second sorting rule is used to sort the uplink transmission windows of each low-latency service.

[0134] Optionally, the sorting logic in this embodiment may include a first sorting rule and / or a second sorting rule. The first sorting rule can be used to sort the uplink transmission windows of low-latency services and non-low-latency services in the ONU's services. Optionally, in this embodiment, the first sorting rule may include adjusting the uplink transmission windows of low-latency services to precede the uplink transmission windows of non-low-latency services. For example, if uplink transmission windows A1, B2, and C2 are the uplink transmission windows of low-latency services, and uplink transmission windows B1 and C1 are the uplink transmission windows of non-low-latency services, then after sorting the uplink transmission windows of low-latency services and non-low-latency services according to the first sorting rule, the sorted order of the uplink transmission windows of low-latency services and non-low-latency services can be as follows: Figure 18 The sorting shown.

[0135] Optionally, the aforementioned second sorting rule can be used to sort the uplink transmission windows of each low-latency service. As an optional implementation, the second sorting rule may include sorting the uplink transmission windows of each low-latency service according to their window length. Optionally, as an optional implementation, the uplink transmission windows of each low-latency service may be sorted in descending order of window length. Alternatively, as another optional implementation, the uplink transmission windows of each low-latency service may be sorted in ascending order of window length. However, it should be noted that... (See also: [link to previous text]). Figure 19 and Figure 20 , Figure 19 This diagram illustrates the sorting results of the uplink transmission windows for each low-latency service, arranged in descending order of window length. Figure 20 To sort the uplink transmission windows of each low-latency service in ascending order of window length, the following diagram illustrates the sorting result of the uplink transmission windows for each low-latency service: Figure 19 and Figure 20 The comparison shows that sorting the uplink transmission windows of each low-latency service in descending order of window length minimizes the number of uplink transmission windows affected by low-latency services. Conversely, sorting them in ascending order of window length will affect the uplink transmission windows of two low-latency services in the next transmission cycle. Therefore, sorting the uplink transmission windows of each low-latency service in descending order of window length is a superior sorting rule, as it minimizes the number of uplink transmission windows affected by low-latency services.

[0136] In this embodiment, the preset sorting logic includes a first sorting rule and / or a second sorting rule. The first sorting rule can sort the uplink transmission windows of low-latency services and the uplink transmission windows of non-low-latency services. The second sorting rule can sort the uplink transmission windows of each low-latency service. This sorting logic considers both the uplink transmission windows of low-latency services and the transmission order of the uplink transmission windows of non-low-latency services. After sorting the uplink transmission windows of the ONU services according to this sorting logic, the uplink transmission windows of the sorted services can further reduce the impact of static windows on the uplink transmission windows of services when transmitting on transmission resources, thereby reducing the latency of ONU data transmission and improving the service quality of ONU uplink transmission.
