[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] The present invention provides a microwave air interface control method and device thereof, and a computer-readable storage medium. By acquiring energy-saving strategy information based on service flow information, and further determining an air interface to be energy-saving in a PLA link based on the energy-saving strategy information, energy-saving processing can be performed on an ODU power supply corresponding to the air interface to be energy-saving, and energy waste of the ODU power supply corresponding to the air interface to be energy-saving can be reduced, thereby realizing air interface energy-saving transmission.

[0030] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0031] like Figure 1 As shown, Figure 1 FIG. 1 is a schematic diagram of a microwave air interface architecture for executing a microwave air interface control method provided by an embodiment of the present invention. Figure 1In the example, the microwave air interface architecture includes a management platform and a microwave network element, and the management platform is connected to the microwave network element.

[0032] The management platform is provided with energy-saving devices, resource modules and databases, and the microwave network element is provided with Ethernet traffic monitoring modules and wireless link management energy-saving control modules.

[0033] The energy-saving device can query data through a database and query corresponding resources through a resource module. Based on the queried data and the queried resources, the energy-saving device can obtain the service flow information of the air interface topology in the microwave network element. The service flow information can be but is not limited to Ethernet flow and the air interface capacity of the PLA link. At the same time, based on the queried data and the queried resources, the energy-saving device can also obtain the calendar information, ODU power type, and ODU power consumption information configured by the user. After obtaining the above information, the energy-saving device can use the above information for big data analysis, thereby obtaining energy-saving strategy information for the microwave network element and sending it to the Ethernet traffic monitoring module. The energy-saving strategy information carries the traffic prediction result for the microwave network element, so that the Ethernet traffic monitoring module can consider the bandwidth utilization of each air interface in the PLA link on the basis of the energy-saving strategy information, thereby determining the air interface to be saved in the air interface topology, and outputting the corresponding energy-saving notification to the wireless link management energy-saving control module. Finally, the wireless link management energy-saving control module implements energy-saving control of the air interface to be saved in the air interface topology according to the air interface topology. Correspondingly, if the air interface that has entered the energy-saving state is to be exited from energy-saving, the Ethernet traffic monitoring module can still obtain the exit energy-saving policy information sent by the energy-saving device and generate an energy-saving policy instruction, so that the wireless link management energy-saving control module can implement energy-saving control of the ODU power supply corresponding to the air interface to be saved according to the exit energy-saving policy instruction.

[0034] The energy-saving device can obtain the corresponding resources in the resource module through a deep convolutional learning network. The deep convolutional learning network can be but is not limited to a deep residual network RES, a deep reinforcement network, etc.

[0035] The database may be, but is not limited to, a historical database, a real-time database, a dynamic database, and a static database.

[0036] The resource module may be, but is not limited to, a dynamic resource library, a static resource library, etc. Various types of network resources may be stored in the resource module, and the network resources may be acquired by the energy-saving device.

[0037] The microwave network element may also be provided with a controller, which may be implemented based on various platforms, such as a Field Programmable Gate Array (FPGA) platform, a Software Defined Network (SDN) platform, etc. The controller is used to switch the service traffic of the air interface to be energy-saving to the other non-energy-saving air interfaces according to the control instructions of the Ethernet traffic monitoring module, thereby ensuring that the service of the air interface to be energy-saving is switched in a lossless or instantaneous manner, preventing service losses that may be easily caused when switching the air interface to be energy-saving, and ensuring that users have stable and reliable network usage performance.

[0038] The microwave network element may include a memory and a processor, wherein the memory and the processor may be connected via a bus or other means.

[0039] The memory, as a non-transient computer-readable storage medium, can be used to store non-transient software programs and non-transient computer executable programs. In addition, the memory may include a high-speed random access memory, and may also include a non-transient memory, such as at least one disk storage device, a flash memory device, or other non-transient solid-state storage device. In some embodiments, the memory may optionally include a memory remotely disposed relative to the processor, and these remote memories may be connected to the processor via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0040] The microwave air interface architecture and application scenarios described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Those skilled in the art will appreciate that with the evolution of the microwave air interface architecture and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0041] It can be understood by those skilled in the art that Figure 1 The microwave air interface architecture shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0042] exist Figure 1 In the microwave air interface architecture shown, the microwave network element can call the microwave air interface control program stored therein to execute the microwave air interface control method.

[0043] Based on the above microwave air interface architecture, various embodiments of the microwave air interface control method of the present invention are proposed.

[0044] like Figure 2 As shown, Figure 2is a flow chart of a microwave air interface control method provided by an embodiment of the present invention. The microwave air interface control method can be applied to Figure 1 The microwave air interface architecture shown in the figure, the control method includes but is not limited to the following steps:

[0045] Step S100, obtaining energy-saving strategy information, where the energy-saving strategy information is obtained based on service flow information;

[0046] Step S200, determining the air interface to be energy-saving in the physical link aggregation PLA link according to the energy-saving strategy information;

[0047] Step S300: performing energy saving processing on the outdoor unit ODU power supply corresponding to the air interface to be energy-saving.

[0048] In one embodiment, the energy-saving strategy information obtained based on the service flow information fully considers the impact of the service flow of the air interface in the PLA link, that is, the energy-saving strategy information is set according to the actual change of the service flow of the air interface in the PLA link. Therefore, the air interface to be energy-saving in the PLA link is determined based on the energy-saving strategy information, so that the air interface to be energy-saving can match the actual service flow in the PLA link, and then the energy-saving processing is performed on the ODU power supply corresponding to the air interface to be energy-saving, so as to prevent the ODU power supply corresponding to the air interface to be energy-saving from being wasted. It can be seen that by implementing the energy-saving control process in the case of microwave air interface transmission as described above, the waste of air interface power supply that needs to be saved can be reduced, which is convenient for realizing air interface energy-saving transmission.

[0049] In one embodiment, the energy-saving process may be to turn off the ODU power corresponding to the air interface to be energy-saving, that is, at this time, the service transmission of the PLA link is completely saturated, and by turning off the ODU power corresponding to the air interface to be energy-saving, the PLA link member corresponding to the air interface to be energy-saving no longer transmits services, and the energy-saving effect can be achieved while meeting the service transmission conditions. In addition, by turning off the ODU power corresponding to the air interface to be energy-saving to achieve energy-saving processing, it is also possible to achieve a transient disconnection operation of the air interface to be energy-saving in the PLA link, thereby achieving a lossless service effect.

[0050] In one embodiment, the energy-saving process may be, but is not limited to, causing the ODU power supply corresponding to the air interface to be energy-saving to enter a standby state, reducing the output power, etc., that is, at this time the service transmission of the PLA link is relatively saturated, and at this time the power consumption of the ODU power supply corresponding to the air interface to be energy-saving is controlled to be relatively reduced, thereby achieving energy-saving effects while meeting service transmission conditions.

[0051] like Figure 3 As shown, in one embodiment, Figure 3 is a flow chart of a microwave air interface control method provided by another embodiment of the present invention, wherein step S300 may include but is not limited to:

[0052] Step S310, obtaining a delay control instruction;

[0053] Step S320: Perform energy saving processing on the ODU power supply corresponding to the air interface to be energy-saving according to the delay control instruction.

[0054] In one embodiment, energy-saving processing is performed on the ODU power supply corresponding to the air interface to be energy-saving based on the delay control instruction. This can ensure that while the ODU power supply is being saved, the control process corresponding to the delay control instruction can be used to enable the service of the air interface to be energy-saving to achieve millisecond-level interruption or no interruption energy-saving effect. Therefore, in the process of executing energy-saving control, a good and stable service network can still be provided to users.

[0055] In one embodiment, in order to more reasonably illustrate the control principle of air interface energy saving, the delay control instruction and the control process corresponding to the delay control instruction, two types of air interface topologies with relatively wide practical applications are described in detail. The two types of air interface topologies include a PLA link topology without an interference cancellation function (i.e., a simple PLA link topology) and a PLA link topology with an interference cancellation function (i.e., an interference cancellation type PLA link topology). Specific embodiments of the control method under the above air interface topologies are given below for description.

[0056] like Figure 4 As shown, Figure 4 FIG. 1 is a schematic diagram of an implementation of a microwave air interface control method provided by an embodiment of the present invention. The microwave air interface control method can be applied to Figure 1 The microwave air interface architecture shown in the figure involves a pure PLA link topology. The specific process of controlling the air interface to enter the energy-saving state is as follows:

[0057] For example, Figure 4As shown, the air interface to be energy-saving in the selected PLA link enters the energy-saving state, and the service traffic carried on the air interface to be energy-saving is switched to the non-energy-saving air interface in the PLA link (which can be achieved by the controller performing a locking operation on the air interface to be energy-saving), and then for the local end of the air interface to be energy-saving, after a delay of 10ms, a 1s first timer is started. When the first timer times out, the ODU power corresponding to the local end of the air interface to be energy-saving is turned off, and at the same time, according to the PLA link topology, it is determined that a neighbor hop message needs to be sent to the opposite network element, so that the opposite network element performs corresponding energy-saving processing according to the neighbor hop message, that is, similarly, the service traffic of the opposite network element is also switched to the non-energy-saving air interface of the opposite end of the PLA link, and the 1s first timer is started. When the first timer times out, the ODU power corresponding to the opposite network element is turned off. Therefore, through the instruction of delaying and starting the first timer, the local end and the opposite end of the air interface to be energy-saving can both enter the energy-saving state synchronously, so that the overall service of the air interface to be energy-saving can achieve millisecond-level interruption or no interruption energy-saving effect, and can still provide users with a good and stable service network during the process of executing energy-saving control.

[0058] Similarly, corresponding to entering energy saving, when the energy-saving air interface enters the energy-saving state, it can also exit energy saving. The specific process is as follows:

[0059] Exemplarily, an air interface in a PLA link that has entered energy-saving state is selected to exit the energy-saving state, and a 1s third timer is started for the air interface. When the third timer times out, the air interface is enabled to receive service traffic again (this can be achieved by releasing the controller's lock operation on the air interface to be energy-saving), and at the same time, the ODU power supply corresponding to the air interface to be energy-saving is turned on. In this case, there is no need to send neighboring hop information to the opposite network element, that is, the above operation is performed directly on the opposite network element, so that the opposite network element also exits the energy-saving state, thereby allowing both the local and opposite ends of the air interface to be energy-saving to exit the energy-saving state.

[0060] It can be seen that since the control method of this embodiment is applied in Figure 1Under the microwave air interface architecture of the illustrated embodiment, the corresponding air interface can be selected to enter energy saving or exit energy saving according to the service carrying status of the PLA link, that is, the ODU power supply corresponding to the corresponding air interface can be selected to be turned on or off according to the service carrying status of the PLA link, and the service traffic of the air interface can be switched or re-received, so that the service resources in the PLA link can achieve lossless balance, that is, the user traffic in the network can be well adapted to carry out service transmission, which can greatly avoid the excess of service resources in the PLA link and achieve the purpose of reasonably and effectively managing the transmission resources of the microwave air interface. At the same time, for both ends of the selected air interface, by sending adjacent hop information, delaying, and starting the corresponding timer, the two ends of the selected air interface can synchronously enter the energy saving state or exit the energy saving state, so that the ODU power supply corresponding to the air interface can be turned off or on accordingly, and the intelligent control of the ODU power supply corresponding to the air interface is realized.

[0061] In summary, the control method of this embodiment can reduce the power waste caused by the PLA link in service transmission. As far as the PLA link is concerned, the purpose of stably controlling the ODU power supply corresponding to the air interface can be achieved, thereby realizing air interface lossless energy-saving transmission. Figure 5 As shown, Figure 5 FIG. 1 is a schematic diagram of an implementation of a microwave air interface control method provided by an embodiment of the present invention. The microwave air interface control method can be applied to Figure 1 The microwave air interface architecture shown in the figure, in order to ensure that the air interface transmission of the PLA link is more stable, each air interface in the simple PLA link topology can be configured as a pair, that is, each air interface is configured as a primary air interface and a backup air interface, the primary air interface and the backup air interface can execute actions synchronously, similarly, the primary air interface and the backup air interface also have opposite network elements, therefore, the control method of the present invention can still choose to open or close the corresponding primary air interface and the backup air interface according to the actual situation of the PLA link, since the previous embodiment has described in detail the energy-saving control process of the air interface under the PLA link, and the basic idea of ​​this embodiment is consistent with that of the previous embodiment, in order to avoid redundancy, this embodiment is not described in detail here, and those skilled in the art can fully understand the microwave air interface control process under other situations according to the content disclosed in this embodiment in combination with the prior art content.

[0062] Therefore, by analyzing the air interface control process of a simple PLA link topology, it can be understood that to determine that the air interface to be energy-saving in the PLA link enters the energy-saving state, it is necessary to make both the local end and the opposite end of the air interface to be energy-saving enter the energy-saving state. In the control process, only one end of the air interface to be energy-saving (such as the local end of the air interface to be energy-saving in this embodiment) needs to be stimulated, and then it can send neighbor hop information to the opposite network element, so that the opposite network element can perform corresponding energy-saving processing according to the neighbor hop message. It can be seen that the local end and the opposite end of the air interface to be energy-saving are connected through the neighbor hop information, so that the ODU power supply corresponding to the air interface to be energy-saving can be controlled more conveniently and reliably. This is because the transmission speed of the neighbor hop message is relatively fast, so it can ensure that the two ends of the air interface to be energy-saving can realize synchronous operation of the hardware, thereby minimizing the impact of external interference signals, so that the service can be interrupted or interrupted to the millisecond level.

[0063] like Figure 6 As shown, Figure 6 FIG. 1 is a schematic diagram of an implementation of a microwave air interface control method provided by an embodiment of the present invention. The microwave air interface control method can be applied to Figure 1 The microwave air interface architecture shown in the figure, the PLA link topology involved is an interference cancellation type PLA link topology, specifically, the PLA link is configured with a cross-polarization interference cancellation (Cross-PolarizationInterference Cancellation, XPIC) function, that is, an air interface in the PLA link has another polarized air interface matched with it, and the air interface and its polarized air interface form an XPIC polarization group, and the specific process of controlling the air interface to enter the energy-saving state is to select some air interfaces in the PLA link to enter the energy-saving state, and switch the service traffic carried on these air interfaces to the remaining air interfaces in the PLA link (which can be achieved by performing a locking operation on these air interfaces through a controller), specifically, according to the number of air interfaces in the XPIC polarization group entering the energy-saving state, corresponding control is performed:

[0064] (1) If both the air interface to be energy-saving and its polarized air interface enter the energy-saving state, the transmission communication between the two air interfaces can be realized based on the polarization function in the XPIC polarization group, without sending neighbor hop information to the opposite network element, and directly shutting down the ODU power of the air interface to be energy-saving and its polarized air interface;

[0065] (2) Figure 6As shown, if the air interface to be energy-saving enters the energy-saving state and the polarized air interface has not entered the energy-saving state, the local end of the air interface to be energy-saving is silenced after a delay of 10ms, and a second timer of 1s is started. When the second timer times out, the ODU power corresponding to the local end of the air interface to be energy-saving is turned off, and the neighbor hop information is sent to the opposite network element, so that the opposite network element performs corresponding energy-saving processing according to the neighbor hop message. That is, similarly, when the opposite network element receives the neighbor hop information, it is silent and starts a second timer of 1s. When the second timer times out, the ODU power corresponding to the opposite network element is turned off. Therefore, both the local end and the opposite end of the air interface to be energy-saving can enter the energy-saving state.

[0066] Similarly, corresponding to entering energy saving, when the air interface to be energy-saving or its polarized air interface enters the energy saving state, it can also be made to exit energy saving. At this time, the third timer of 1s is started, specifically:

[0067] (3) If both polarized air interfaces in the XPIC polarization group exit the energy-saving state, the air interface to be energy-saving does not need to send neighbor hop information to the opposite network element, and the ODU power of the air interface to be energy-saving and the polarized air interface is directly turned on;

[0068] (4) If only one air interface in the XPIC polarization group exits the energy-saving state, for the local end of the air interface, the polarization information is sent to the local end of the polarization air interface to prompt the local end of the polarization air interface to send the neighbor hop information to its opposite end network element, and at the same time, the ODU power of the local end of the air interface is turned on after a delay of 20ms, so that the local end of the air interface exits the energy-saving state; when the opposite end network element of the polarization air interface receives the neighbor hop information, the neighbor hop information is forwarded to the opposite end network element of the corresponding polarization air interface, so that it turns on the ODU power, so that the opposite end of the air interface exits the energy-saving state, and finally enables the air interface to receive service traffic again (this can be achieved by releasing the controller's locking operation on the air interface to be energy-saving). It can be seen that when the PLA link is configured with the XPIC function, relevant information can be transmitted based on the polarization air interface when exiting the energy-saving state, so that the stable control of the ODU power between the local end and the opposite end of the air interface to be exited from the energy-saving state can be achieved.

[0069] It can be seen that since the control method of this embodiment is applied in Figure 1Under the microwave air interface architecture of the illustrated embodiment, the corresponding air interface can be selected to enter energy saving or exit energy saving according to the service carrying state of the interference cancellation PLA link topology, that is, the ODU power supply corresponding to the corresponding air interface can be selected to be turned on or off according to the service carrying state of the interference cancellation PLA link topology, so that the service resources in the interference cancellation PLA link topology are saturated, that is, the user traffic in the network can be well adapted to perform service transmission, which can greatly avoid the excess of service resources in its link, and achieve the purpose of reasonably and effectively managing the transmission resources of the microwave air interface. In particular, when the interference cancellation PLA link topology is running, the air interface of each PLA member will receive interference information other than the air interface. In order to eliminate the interference information, this embodiment achieves the technical effect of eliminating interference by sending polarization information and neighbor hop information, so that the service resources in the interference cancellation PLA link topology can achieve lossless balance, and by sending neighbor hop information, the two ends of the selected air interface can also be synchronously entered into the energy saving state or exited the energy saving state, so that the ODU power supply corresponding to the air interface can be correspondingly turned off or turned on, and the intelligent control of the ODU power supply corresponding to the air interface is realized.

[0070] In summary, the control method of this embodiment can reduce the power waste caused by the interference cancellation PLA link topology in service transmission. As for the interference cancellation PLA link topology as a whole, the purpose of stably controlling the ODU power supply corresponding to the air interface can be achieved, thereby realizing air interface energy-saving transmission.

[0071] Based on the above embodiments, Figure 7 As shown, Figure 7 FIG. 1 is a schematic diagram of an implementation of a microwave air interface control method provided by an embodiment of the present invention. The microwave air interface control method can be applied to Figure 1 The microwave air interface architecture shown in the figure, in order to ensure that the air interface transmission of the PLA link is more stable, each air interface in the interference cancellation type PLA link topology can be configured as a pair, that is, each air interface is configured as a main air interface and a backup air interface, the main air interface and the backup air interface can execute actions synchronously, similarly, the main air interface and the backup air interface also have opposite network elements, therefore, the control method of the present invention can still choose to open or close the corresponding main air interface and the backup air interface according to the actual situation of the PLA link, since the previous embodiment has described in detail the energy-saving control process of the air interface under the PLA link, and the basic idea of ​​this embodiment is consistent with that of the previous embodiment, in order to avoid redundancy, this embodiment is not described in detail here, and those skilled in the art can fully understand the microwave air interface control process under other circumstances according to the content disclosed in this embodiment in combination with the prior art content.

[0072] like Figure 8 As shown, Figure 81 is a schematic diagram of an execution of a microwave air interface control method provided by an embodiment of the present invention. The PLA link topology involved is an interference cancellation PLA link topology. The microwave air interface control method can be applied to Figure 1 The microwave air interface architecture shown in the figure, specifically, the PLA link is not only configured with an XPIC function, but also configured with a Multiple-Input Multiple-Output (MIMO) function, that is, an air interface in the PLA link has another polarized air interface matched with it, and the air interface and its polarized air interface form a polarization group, and the polarization group can be an XPIC polarization group or a MIMO polarization group, and the PLA link includes at least two polarization groups. Since the PLA link includes a case where the polarization group is greater than two groups, compared with the case where the polarization group is exactly two groups, its air interface control process is similar to avoid redundancy. This embodiment is only described based on the case where the polarization group is exactly two groups. Those skilled in the art can fully understand the microwave air interface control process under other situations according to the content disclosed in this embodiment in combination with the prior art content.

[0073] Exemplarily, the control process of the PLA link is to select certain air interfaces in the PLA link to enter the energy-saving state, and switch the service traffic carried on these air interfaces to the remaining air interfaces in the PLA link (which can be achieved by the controller performing a locking operation on these air interfaces). Specifically, the corresponding control is performed according to the number of four air interfaces in the two polarization groups entering energy saving:

[0074] (1) If all four air interfaces enter the energy-saving state, there is no need to send neighbor hop information to the peer network element, and the ODU power of the four air interfaces can be directly turned off;

[0075] (2) If one, two or three air interfaces enter the energy-saving state, the corresponding air interface is controlled to enter the energy-saving state accordingly, that is, the energy-saving control of the air interface is realized through message interaction between the air interface and its polarized air interface. In short, no matter one, two or three air interfaces enter the energy-saving state, they are all controlled based on the above process. Therefore, to avoid redundancy, this embodiment is only described by taking one of the air interfaces entering the energy-saving state. Those skilled in the art can fully understand the microwave air interface control process under other situations based on the contents disclosed in this embodiment and the contents of the prior art.

[0076] For example, Figure 8As shown, the local end of the air interface to be energy-saving sends neighbor hop information to the air interface of the opposite end, is silent after a delay of 10ms, and starts a second timer of 1s, and sends a first trigger information to its polarized air interface (XPIC polarized air interface or MIMO polarized air interface) at the same time, so that the interference function (XPIC interference function or MIMO interference function) between the polarized air interface and the air interface to be energy-saving is offset; when the opposite end of the air interface to be energy-saving receives the neighbor hop information, it is silent and starts the second timer of 1s, and sends the second trigger information to the opposite end of the polarized air interface, so that the interference function between the opposite end of the air interface to be energy-saving and the polarized air interface opposite end is offset, and finally, after the second timer times out, the ODU power corresponding to the local end and the opposite end of the air interface to be energy-saving is turned off to achieve an energy-saving control effect.

[0077] Among them, Fig. 10A As shown, Fig. 10A This is a schematic diagram of interference signals between air interfaces in an existing PLA link. Generally, the interference signals between air interfaces in a PLA link are Fig. 10A The situation shown is presented; on the other hand, Fig. 10B is a schematic diagram of the interference cancellation function in the PLA link provided by an embodiment of the present invention. Since the first trigger information is used to turn off the interference function between the polarized air interface and the air interface to be energy-saving, and the second trigger information is used to turn off the interference function between the air interface to be energy-saving and the polarized air interface. Therefore, refer to Fig. 10B That is, when the ODU power of the air interface to be energy-saving is turned off at the local end and the opposite end, the interference signal of the non-energy-saving part of the PLA link is eliminated, thereby reducing the interference effect of the non-energy-saving part of the link on the air interface to be energy-saving, so as to achieve the effect of instant service interruption. In fact, Fig. 10A and Fig. 10B As shown in the figure, when the PLA link with interference cancellation function operates normally, each PLA member air interface will receive interference signals not from the air interface. Therefore, the interference signals can be cancelled by XPIC or MIMO technology to restore the original signal, thereby reducing the impact of the non-energy-saving part of the link on the signal of the corresponding air interface.

[0078] Similarly, corresponding to entering energy saving, the air interface that has entered energy saving can exit the energy saving state, and at this time, the third timer of 1s is started, specifically:

[0079] (3) If all four air interfaces exit the energy-saving state, there is no need to send neighbor hop information to the peer network element, and the ODU power supplies of the four air interfaces are directly turned off;

[0080] (4) If one, two or three air interfaces exit the energy-saving state, the corresponding air interface is controlled to exit the energy-saving state accordingly, that is, the air interface is controlled to exit the energy-saving state through message interaction between the air interface and its polarized air interface. In short, no matter one, two or three air interfaces exit the energy-saving state, they are all controlled based on the above process. Therefore, to avoid redundancy, this embodiment only describes one of the air interfaces exiting the energy-saving state. Those skilled in the art can fully understand the microwave air interface control process under other circumstances based on the contents disclosed in this embodiment and the prior art.

[0081] Exemplarily, the local end of the energy-saving air interface to be exited turns on the ODU power after a delay of 20ms, and at the same time sends the second trigger information to its polarized air interface (XPIC polarized air interface or MIMO polarized air interface), so that the local end of the polarized air interface can forward the neighbor hop information to the opposite end of the polarized air interface; when the opposite end of the polarized air interface receives the neighbor hop information, it forwards the neighbor hop information to the opposite end of the energy-saving air interface to be exited, so that the ODU power corresponding to the opposite end of the energy-saving air interface to be exited is turned on to exit the energy-saving state. Finally, when the third timer times out, both the local end and the opposite end of the energy-saving air interface to be exited can receive service traffic again (this can be achieved by releasing the controller's locking operation on the energy-saving air interface to be exited).

[0082] On the basis of the above embodiment, in order to ensure that the air interface transmission of the PLA link is more stable, each air interface in the interference cancellation PLA link topology can be configured as a pair, that is, each air interface is configured as a primary air interface and a backup air interface, and the primary air interface and the backup air interface can execute actions synchronously. Similarly, the primary air interface and the backup air interface also have opposite network elements. Therefore, the control method of the present invention can still choose to open or close the corresponding primary air interface and the backup air interface according to the actual situation of the PLA link. Since the previous embodiment has described in detail the energy-saving control process of the air interface under the PLA link, and the basic idea of ​​this embodiment is consistent with that of the previous embodiment, in order to avoid redundancy, this embodiment will not be described in detail here. Those skilled in the art can fully understand the microwave air interface control process under other situations based on the content disclosed in this embodiment in combination with the prior art content.

[0083] It can be seen that since the control method of this embodiment is applied in Figure 1Under the microwave air interface architecture of the illustrated embodiment, the corresponding air interface can be selected to enter or exit energy saving according to the service carrying state of the interference cancellation PLA link topology, that is, the ODU power supply corresponding to the corresponding air interface can be selected to be turned on or off according to the service carrying state of the interference cancellation PLA link topology, so that the service resources in the interference cancellation PLA link topology are saturated, that is, the user traffic in the network can be well adapted to perform service transmission, which can greatly avoid the excess of service resources in its link, and achieve the purpose of reasonably and effectively managing the transmission resources of the microwave air interface. In particular, when the interference cancellation PLA link topology with XPIC or MIMO function is running, the air interface of each PLA member will receive interference information other than the air interface. In this embodiment, the interference is eliminated by sending the first trigger information, the second trigger information and the neighbor hop information, so that the service resources in the interference cancellation PLA link topology can achieve lossless balance, and by sending the neighbor hop information, the two ends of the selected air interface can also be synchronously entered into or exited from the energy saving state, so that the ODU power supply corresponding to the air interface can be correspondingly turned off or turned on, and the intelligent control of the ODU power supply corresponding to the air interface is realized.

[0084] In summary, the control method of this embodiment can reduce the power waste caused by the interference cancellation PLA link topology in service transmission. As for the interference cancellation PLA link topology as a whole, the purpose of stably controlling the ODU power supply corresponding to the air interface can be achieved, thereby realizing air interface energy-saving transmission.

[0085] in, Fig.9A It is a schematic diagram of the service flow of each air interface in the existing PLA link. In general, the service flow in the PLA link is fixed to flow into the corresponding data selector, such as Fig.9A As shown; Fig. 9B FIG. 1 is a schematic diagram of a service switching operation of an air interface to be energy-saving in a PLA link provided by an embodiment of the present invention. In fact, by analyzing the air interface control under the above-mentioned PLA links, it can be understood that no matter what the air interface topology of the PLA link is, that is, no matter whether the air interface topology of the PLA link belongs to a simple PLA link topology or an interference cancellation PLA link topology, Fig. 9B As shown, after the air interface to be energy-saving in the PLA link is determined, the service traffic of the air interface to be energy-saving can be switched to the other non-energy-saving air interfaces (i.e., the energy-saving air interface can be switched from the energy-saving air interface to the energy-saving air interface). FIG. 9A to FIG. 9B Control conversion), thereby ensuring that the service of the air interface to be energy-saving is switched in a lossless or instantaneous manner, that is, the remaining non-energy-saving air interfaces are used to share the service of the air interface to be energy-saving, thereby preventing the service loss that is easily caused when switching the air interface to be energy-saving, ensuring that users have stable and reliable network usage performance, and improving users' network experience.

[0086] Correspondingly, when exiting energy-saving control, no matter what the air interface topology of the PLA link is, that is, no matter whether the air interface topology of the PLA link belongs to a simple PLA link topology or an interference cancellation PLA link topology, after determining the air interface to be exited from energy saving in the PLA link, it is possible to switch the service traffic of other air interfaces to the air interface, that is, restore the service volume carrying of the air interface, thereby ensuring that the service of the air interface to be energy-saving is restored in a lossless or instantaneous manner, that is, restore the service of the air interface to be energy-saving, thereby ensuring that users have stable and reliable network usage performance, thereby improving users' network experience.

[0087] Moreover, on the one hand, based on the consideration of pure PLA link topology, a delay of 10ms is adopted, and the first timer is started, and when the first timer times out, the specific operation of turning off the ODU power supply corresponding to the air interface to be energy-saving is carried out, wherein the main function of the delay operation and the setting of the first timer is to enable both the local end and the opposite end of the air interface to be energy-saving to enter the energy-saving state synchronously, therefore, the overall service of the air interface to be energy-saving can achieve the energy-saving effect of millisecond-level interruption or no interruption, and can still provide users with a good and stable service network in the process of executing energy-saving control. In fact, the delay time can also adopt other specific parameters, which can be specifically considered and set according to the structure of the air interface topology. The above embodiment does not strictly limit the specific value of the delay time. Similarly, in the process of exiting the energy-saving control process, a delay of 20ms is adopted before turning on the corresponding OD U power supply can also enable both the local end and the opposite end of the air interface to be energy-saving to synchronously exit the energy-saving state, so that the overall service of the air interface to be energy-saving can achieve millisecond-level interruption or no interruption energy-saving effect, and can still provide users with a good and stable service network in the process of exiting energy-saving control; on the other hand, based on the interference cancellation PLA link topology, silence is adopted after a delay of 10ms, and the second timer is started, and when the second timer times out, the specific operation of turning off the ODU power supply corresponding to the air interface to be energy-saving is carried out. For the energy-saving control of the interference cancellation PLA link topology, the ODU power supply is silenced to prevent the related polarization groups in the link from continuing to generate large interference, so that the air interface energy-saving control is more stable, so that the overall service of the air interface to be energy-saving can easily achieve millisecond-level interruption or no interruption energy-saving effect.

[0088] In order to more reasonably explain the integrated working principle of the present invention, so that those skilled in the art can more clearly understand the design ideas of the present invention, please refer to Fig.11 The following is a description of the specific execution process for the air interface to enter the energy-saving state.

[0089] like Fig.11As shown, first, the energy-saving strategy information is obtained, and then the air interface to be energy-saving is determined based on the energy-saving strategy information and a locking operation is performed on it, so as to ensure that the PLA link service is lossless. Next, for the ODU power supply side corresponding to the air interface to be energy-saving, it is necessary to judge its air interface topology type, so as to decide whether it is necessary to notify the opposite network element according to the air interface topology type. Accordingly, two execution modes are determined. Mode one is that the ODU power supply corresponding to the air interface to be energy-saving can be directly turned off without notifying the opposite network element. Mode two is that the opposite network element needs to be notified, that is, the neighboring hop information is sent to the opposite network element, and the air interface to be energy-saving is delayed and silently processed, so as to finally realize the ODU power supply corresponding to both ends of the air interface to be energy-saving is turned off.
