It will be appreciated by those skilled in the art that the microwave air interface architecture shown in fig. 1 is not intended to limit embodiments of the present invention, and may include more or fewer components than shown, or some components may be combined, or a different arrangement of components.
In the microwave air interface architecture shown in fig. 1, the microwave network element may call a microwave air interface control program stored therein to execute the microwave air interface control method.
Based on the above microwave air interface architecture, embodiments of the microwave air interface control method of the present invention are provided.
As shown in fig. 2, fig. 2 is a flowchart of a microwave air interface control method according to an embodiment of the present invention, where the microwave air interface control method may be applied to the microwave air interface architecture shown in fig. 1, and the control method includes, but is not limited to, the following steps:
step S100, obtaining energy-saving strategy information, wherein the energy-saving strategy information is obtained based on the service flow information;
step S200, determining an empty port to be energy-saved in a physical link aggregation PLA link according to the energy-saving strategy information;
step S300, performing energy saving processing on the outdoor unit ODU power supply corresponding to the air interface to be energy-saved.
In an embodiment, the energy-saving policy information obtained based on the service traffic information fully considers the influence caused by the service traffic of the air interface in the PLA link, that is, the energy-saving policy information is set for the actual change of the service traffic of the air interface in the PLA link, so that the air interface to be energy-saved in the PLA link is determined based on the energy-saving policy information, so that the air interface to be energy-saved can be matched with the actual condition of the service traffic in the PLA link, and then energy-saving processing is performed for the ODU power supply corresponding to the air interface to be energy-saved, thereby preventing the ODU power supply corresponding to the air interface to be energy-saved from being wasted. Therefore, by implementing the energy-saving control flow under the condition of microwave air interface transmission, the waste of air interface power supplies needing energy saving can be reduced, and the air interface energy-saving transmission is convenient to implement.
In an embodiment, the energy saving process may be to turn off the ODU power supply corresponding to the air interface to be energy saved, that is, service transmission of the PLA link is completely saturated at this time, and by turning off the ODU power supply corresponding to the air interface to be energy saved, a PLA link member corresponding to the air interface to be energy saved no longer transmits a service, and an energy saving effect can be achieved under the condition that a service transmission condition is satisfied. In addition, energy-saving processing is realized by closing the ODU power supply corresponding to the air interface to be energy-saved, and instantaneous interruption operation of the air interface to be energy-saved in the PLA link can be realized, so that the service lossless effect can be achieved.
In an 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-saved to enter a standby state, reducing output power, and the like, that is, at this time, service transmission of the PLA link is relatively saturated, and at this time, controlling power consumption of the ODU power supply corresponding to the air interface to be energy-saved to be relatively reduced, so that an energy saving effect can be achieved under the condition that a service transmission condition is satisfied.
As shown in fig. 3, in an embodiment, fig. 3 is a flowchart of a microwave air interface control method according to another embodiment of the present invention, where step S300 may include, but is not limited to:
step S310, acquiring a delay control instruction;
step S320, perform energy saving processing on the ODU power supply corresponding to the air interface to be energy-saved according to the delay control instruction.
In an embodiment, energy saving processing is performed on the ODU power supply corresponding to the air interface to be energy-saved based on the delay control instruction, so that energy saving of the ODU power supply can be ensured, and meanwhile, a service of the air interface to be energy-saved can obtain an energy saving effect of millisecond-level interruption or no interruption through a control flow corresponding to the delay control instruction, and therefore, a good and stable service network can be provided for a user in the process of performing energy saving control.
In an embodiment, in order to more reasonably describe the air interface energy saving control principle, the delay control instruction, and the control flow corresponding to the delay control instruction, two types of air interface topologies with wider practical application are described in detail, where the two types of air interface topologies include a PLA link topology without an interference cancellation function (i.e., a pure PLA link topology) and a PLA link topology with an interference cancellation function (i.e., an interference cancellation PLA link topology), and specific embodiments of the control method under the air interface topology are respectively described below.
As shown in fig. 4, fig. 4 is a schematic diagram illustrating an execution of a microwave air interface control method according to an embodiment of the present invention, where the microwave air interface control method is applicable to a microwave air interface architecture as shown in fig. 1, a related PLA link topology is a pure PLA link topology, and a specific process of controlling an air interface to enter an energy saving state includes:
exemplarily, as shown in fig. 4, a to-be-energy-saving air interface in a PLA link is selected to enter an energy-saving state, and a service flow carried on the to-be-energy-saving air interface is switched to a non-energy-saving air interface in the PLA link (which can be implemented by a controller performing a locking operation on the to-be-energy-saving air interface), then, for a local end of the to-be-energy-saving air interface, after delaying for 10ms, a 1s first timer is started, and after the first timer expires, an ODU power supply corresponding to the local end of the to-be-energy-saving air interface is closed, and meanwhile, according to the PLA link topology, it is determined that an adjacent hop message needs to be sent to an opposite-end network element, so that the opposite-end network element performs a corresponding energy-saving process according to the adjacent hop message, that is, similarly, a service flow of the opposite-end network element is also switched to the non-energy-saving air interface of the PLA link opposite end, and the 1s first timer is started, and, after the first timer expires, the ODU power supply corresponding to the opposite-end network element is closed, therefore, by delaying and starting the instruction of the first timer, both the local terminal and the opposite terminal of the air interface to be energy-saving can synchronously enter the energy-saving state, so that the whole service of the air interface to be energy-saving can obtain the energy-saving effect of millisecond-level interruption or no interruption, and a good and stable service network can still be provided for a user in the process of executing energy-saving control.
Similarly, corresponding to entering energy saving, when the energy saving air interface enters an energy saving state, the air interface can also exit energy saving, and the specific flow is as follows:
illustratively, an air interface which has entered energy saving in the PLA link is selected to exit the energy saving state, a 1s third timer is started for the air interface, and when the third timer times out, the air interface is enabled to receive service traffic again (which can be achieved by releasing the locking operation of the controller on the air interface to be energy saving), and simultaneously an ODU power supply corresponding to the air interface to be energy saving is started.
It can be seen that, because the control method of this embodiment is applied to the microwave air interface architecture of the embodiment shown in fig. 1, a corresponding air interface can be selected according to the service bearable state of the PLA link to enter energy saving or exit energy saving, that is, the ODU power corresponding to the corresponding air interface can be selectively turned on or off according to the service bearable state 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 be losslessly balanced, that is, the service transmission can be performed by well adapting to the user traffic in the network, which can greatly avoid the surplus of the service resources in the PLA link, and achieve the purpose of reasonably and effectively controlling the transmission resources of the microwave air interface, and at the same time, for both ends of the selected air interface, the two ends of the selected air interface can synchronously enter energy saving state or exit energy saving state by sending adjacent hop information, delaying and starting the matching operation of a corresponding timer, accordingly, the ODU power supply corresponding to the air interface can be correspondingly closed or opened, and intelligent control over the ODU power supply corresponding to the air interface is achieved.
In summary, the control method of this embodiment can reduce the power waste caused by the PLA link in the service transmission, and as for the PLA link as a whole, the purpose of stably controlling the ODU power corresponding to the air interface can be achieved, so that lossless energy-saving transmission of the air interface can be achieved. On the basis of the foregoing embodiment, as shown in fig. 5, fig. 5 is an execution schematic diagram of a microwave air interface control method provided in an embodiment of the present invention, where the microwave air interface control method may be applied to a microwave air interface architecture as shown in fig. 1, and in order to ensure that air interface transmission of a PLA link is more stable, each air interface in a pure PLA link topology may be configured as a pair, that is, each air interface is configured as a primary air interface and a standby air interface, and the primary air interface and the standby air interface can perform actions synchronously, and similarly, the primary air interface and the standby air interface also have an opposite-end network element, so that the control method of the present invention may still select to open or close the corresponding primary air interface and the standby air interface according to the actual situation of the PLA link, because the energy saving control flow of the air interface under the PLA link has been described in detail in the foregoing embodiment, and the basic ideas of this embodiment are consistent with those of the foregoing embodiment, in order to avoid redundancy, the embodiment is not described in detail herein, and those skilled in the art can fully understand the microwave air interface control flow in other situations according to the disclosure of the embodiment and the content of the prior art.
Therefore, by analyzing the air interface control flow of the pure PLA link topology, it can be known that determining that the air interface to be energy-saving in the PLA link enters an energy-saving state, and it is necessary to make both the home terminal and the opposite terminal of the air interface to be energy-saving enter the energy-saving state, and in the control flow, only one end of the air interface to be energy-saving (for example, the home terminal of the air interface to be energy-saving in this embodiment) needs to be excited, so that the opposite terminal network element can execute corresponding energy-saving processing according to the adjacent hop message by sending the adjacent hop information to the opposite terminal network element, and thus, the connection between the home terminal and the opposite terminal of the air interface to be energy-saving is established through the adjacent hop information, so that the ODU power supply corresponding to the air interface to be energy-saving can be controlled more conveniently and reliably, because the transmission speed of the adjacent hop message is relatively fast, it can be ensured that the hardware is synchronously operated at both ends of the air interface to be energy-saving, thereby maximally weakening the influence of external interference signals, so that traffic implementation glitches or outages can be on the order of milliseconds.
As shown in fig. 6, fig. 6 is a schematic diagram illustrating an implementation of a microwave air interface control method according to an embodiment of the present invention, the microwave air interface control method can be applied to a microwave air interface architecture as shown in fig. 1, the related PLA link topology is an Interference Cancellation type PLA link topology, specifically, the PLA link is configured with a Cross-Polarization Interference Cancellation (XPIC) function, that is, one air interface in the PLA link has another polarized air interface matched with it, and the air interface and its polarized air interface form XPIC polarized group, the specific flow of controlling the air interface to enter the energy-saving state is that some air interfaces in the PLA link are selected to enter the energy-saving state, and switching the service flows loaded on the air interfaces to the rest of air interfaces in the PLA link (which can be realized by the controller performing locking operation on the air interfaces), specifically, performing corresponding control according to the number of energy saving entries of the air interfaces in the XPIC polarization group:
(1) if the air interface to be energy-saving and the polarized air interface thereof both enter the energy-saving state, based on the polarization function in the XPIC polarization group, the transmission communication between the two air interfaces can be realized, adjacent hop information does not need to be sent to an opposite terminal network element, and the ODU power supply of the air interface to be energy-saving and the polarized air interface thereof is directly closed;
(2) as shown in fig. 6, if the air interface to be energy-saving enters an energy-saving state and the polarized air interface does not enter the energy-saving state, delaying the local terminal of the air interface to be energy-saving by 10ms and then muting, starting a 1s second timer, when the second timer is overtime, closing the ODU power supply corresponding to the local terminal of the air interface to be energy-saving, and sending the adjacent hop information to the opposite terminal network element, so that the opposite terminal network element performs corresponding energy-saving processing according to the adjacent hop information, that is, similarly, when the opposite terminal network element receives the adjacent hop information, muting and starting the 1s second timer, and when the second timer is overtime, closing the ODU power supply corresponding to the opposite terminal network element, so that both the local terminal and the opposite terminal of the air interface to be energy-saving can perform the energy-saving state.
Similarly, corresponding to entering energy saving, when the energy saving air interface or the polarized air interface enters the energy saving state, the energy saving air interface can also exit energy saving, and at this time, a 1s third timer is started, specifically:
(3) if both the two polarized air interfaces in the XPIC polarized group exit the energy-saving state, the air interface to be energy-saving does not need to send adjacent hop information to an opposite terminal network element, and the ODU power supplies of the air interface to be energy-saving and the polarized air interfaces are directly opened;
(4) if only one air interface in the XPIC polarization group exits from the energy-saving state, aiming at the air interface local end, polarization information is sent to the polarization air interface local end so as to prompt the polarization air interface local end to send adjacent hop information to an opposite terminal network element, and an ODU power supply of the air interface local end is turned on after 20ms delay so that the air interface local end exits from the energy-saving state; after receiving the adjacent hop information, the opposite-end network element of the polarized air interface forwards the adjacent hop information to the opposite-end network element corresponding to the polarized air interface, so that the opposite-end network element of the polarized air interface opens an ODU power supply, the opposite end of the air interface exits from an energy-saving state, and finally the air interface can receive service traffic again (which can be realized by releasing locking operation of the controller on the air interface to be energy-saved). Therefore, when the PLA link is configured with an XPIC function, the PLA link can transmit related information based on the polarized air interface when exiting the energy saving state, so that stable control of the ODU power between the local terminal and the opposite terminal that are to exit the energy saving air interface can be achieved.
It can be seen that, because the control method of this embodiment is applied to the microwave air interface architecture of the embodiment shown in fig. 1, a corresponding air interface can be selected to enter energy saving or exit energy saving according to the service bearable state of the interference cancellation type PLA link topology, that is, the ODU power corresponding to the corresponding air interface can be selected to be turned on or turned off according to the service bearable state of the interference cancellation type PLA link topology, so that the service resources in the interference cancellation type PLA link topology are saturated, that is, the service transmission can be performed by well adapting to the user traffic in the network, which can greatly avoid the surplus of the service resources in the link, and achieve the purpose of reasonably and effectively controlling the transmission resources of the microwave air interface, in particular, when the interference cancellation type PLA link topology is operating, each air interface of a PLA member receives interference information other than the air interface, and in order to eliminate the interference information, in this embodiment, the technical effect of eliminating interference is obtained by sending the polarization information and the adjacent hop information, so that service resources in the interference cancellation type PLA link topology can reach lossless balance, and by sending the adjacent hop information, the two ends of the selected air interface can synchronously enter an energy saving state or exit the energy saving state, so that the ODU power supply corresponding to the air interface can be correspondingly turned off or on, and the intelligent control of the ODU power supply corresponding to the air interface is realized.
In summary, the control method of this embodiment can reduce power waste caused by the interference cancellation type PLA link topology in service transmission, and as for the interference cancellation type PLA link topology as a whole, the purpose of stably controlling the air interface corresponding to the ODU power source can be achieved, so that energy-saving transmission of the air interface can be achieved.
On the basis of the foregoing embodiment, as shown in fig. 7, fig. 7 is a schematic execution diagram of a microwave air interface control method provided in an embodiment of the present invention, where the microwave air interface control method may be applied to a microwave air interface architecture as shown in fig. 1, and in order to ensure that air interface transmission of a PLA link is more stable, each air interface in the interference cancellation-type PLA link topology may be configured as a pair, that is, each air interface is configured as a main air interface and a standby air interface, and the main air interface and the standby air interface can perform actions synchronously, and similarly, the main air interface and the standby air interface also have opposite-end network elements, so that the control method of the present invention may still select to open or close the corresponding main air interface and standby air interface according to the actual situation of the PLA link, because the energy saving control flow under the PLA link has been described in detail in the foregoing embodiment, and the present embodiment is consistent with the basic idea of the foregoing embodiment, in order to avoid redundancy, the embodiment is not described in detail herein, and those skilled in the art can fully understand the microwave air interface control flow in other situations according to the disclosure of the embodiment and the content of the prior art.
As shown in fig. 8, fig. 8 is an execution schematic diagram of a microwave air interface control method according to an embodiment of the present invention, where the PLA link topology involved is an interference-cancellation PLA link topology, and the microwave air interface control method can be applied to the microwave air interface architecture shown in fig. 1, specifically, the PLA link is configured with not only an XPIC function but also a Multiple-Input Multiple-Output (MIMO) function, that is, an air interface in the PLA link has another polarization air interface matched with the air interface, the air interface and the polarization air interface form a polarization group, the polarization group may be an XPIC polarization group or an MIMO polarization group, and the PLA link at least includes two polarization groups, and since the PLA link includes more than two polarization groups, compared with the case that the polarization groups are exactly two, the air interface control flow is similar, so as to avoid redundancy, this embodiment only describes based on the case that the polarization groups are exactly two polarization groups, those skilled in the art can fully understand the microwave air interface control flow in other situations according to the disclosure of the present embodiment and the contents of the prior art.
Illustratively, the control flow of the PLA link is to select some air interfaces in the PLA link to enter an energy saving state, and switch the service flows carried on the air interfaces to the remaining air interfaces in the PLA link (which may be implemented by a controller executing a locking operation on the air interfaces), specifically, perform corresponding control according to the number of energy saving entries of four air interfaces in two polarization groups:
(1) if the four air interfaces all enter the energy-saving state, the ODU power supplies of the four air interfaces are directly closed without sending adjacent hop information to an opposite terminal network element;
(2) if one, two, or three air interfaces enter the energy saving state, the corresponding air interface is correspondingly controlled to enter energy saving, that is, energy saving control of the air interface is realized through message interaction between the air interface and the polarized air interface thereof.
Exemplarily, as shown in fig. 8, a local end of an air interface to be energy-saving sends adjacent hop information to an air interface of an opposite end, and silences after delaying for 10ms, and starts a 1s second timer, 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 an interference function (XPIC interference function or MIMO interference function) between the polarized air interface and the air interface to be energy-saving is cancelled; and when the opposite end of the air interface to be energy-saving receives the adjacent hop information, silencing and starting a 1s second timer, and simultaneously sending second trigger information to the opposite end of the polarized air interface, so that the interference cancellation function between the opposite end of the air interface to be energy-saving and the opposite end of the polarized air interface is realized, and finally, after the second timer is overtime, closing the ODU power supply corresponding to the local end and the opposite end of the air interface to be energy-saving, and achieving the energy-saving control effect.
As shown in fig. 10A, fig. 10A is a schematic diagram of interference signals between air interfaces in an existing PLA link, and generally, the interference signals of the air interfaces in the PLA link are presented in the situation shown in fig. 10A; on the other hand, fig. 10B is a schematic diagram of an interference cancellation function in a PLA link according to an embodiment of the present invention, where the first trigger information is used to close an interference function between a polarized air interface and an air interface to be saved, and the second trigger information is used to close an interference function between an opposite end of the air interface to be saved and an opposite end of the polarized air interface, so referring to fig. 10B, that is, under a condition that an ODU power supply of a local end and an opposite end of the air interface to be saved is closed, an interference signal of a non-energy-saving partial link in the PLA link disappears, so as to reduce an interference influence of the non-energy-saving partial link on the air interface to be saved, so as to achieve an effect of service instantaneous interruption, in practice, as shown in fig. 10A and 10B, when the PLA link with the interference cancellation function normally operates, each PLA member receives an interference signal of the non-local air interface, so that the interference signal cancellation is performed by an XPIC or MIMO technology, the original signal can be recovered, so that the signal influence of the link of the non-energy-saving part on the corresponding air interface is reduced.
Similarly, corresponding to entering energy saving, the air interface that has entered energy saving can exit the energy saving state, and at this time, a 1s third timer is started, specifically:
(3) if the four air interfaces exit the energy-saving state, the ODU power supplies of the four air interfaces are directly closed without sending adjacent hop information to an opposite terminal network element;
(4) if one, two, or three air interfaces exit the energy saving state, the corresponding air interface is correspondingly controlled to exit the energy saving, that is, the air interface and the polarized air interface thereof interact through messages to realize the exit energy saving control of the air interface.
Exemplarily, after the local terminal of the energy-saving air interface is exited, the ODU power supply is turned on after 20ms delay, and meanwhile, the second trigger information is sent to a polarized air interface (XPIC polarized air interface or MIMO polarized air interface) thereof, so that the polarized air interface local terminal can forward adjacent hop information to a polarized air interface opposite terminal; after the polarized air interface opposite terminal receives the adjacent hop information, the adjacent hop information is forwarded to the energy-saving air interface opposite terminal to be quitted, so that the ODU power supply corresponding to the energy-saving air interface opposite terminal to be quitted is turned on to quit the energy-saving state, and finally, when the third timer is overtime, the local terminal and the opposite terminal to be quitted the energy-saving air interface can both receive the service flow again (which can be realized by releasing the locking operation of the controller on the energy-saving air interface to be quitted).
On the basis of the above embodiments, in order to ensure that air interface transmission of the PLA link is more stable, each air interface in the interference-destructive PLA link topology may be configured as a pair, i.e., each air interface is configured as a primary air interface and a standby air interface, which can perform actions synchronously, and, as such, the main air interface and the standby air interface also have opposite terminal network elements, therefore, the control method of the invention can still select to open or close the corresponding main air interface and the standby air interface according to the actual situation of the PLA link, since the previous embodiment has described the energy saving control flow of the PLA link lower air interface in detail, and the basic idea of this embodiment is consistent with that of the previous embodiment, in order to avoid redundancy, the present embodiment is not described in detail herein, and those skilled in the art can fully understand the microwave air interface control flow in other situations according to the disclosure of the present embodiment and the content of the prior art.
It can be seen that, because the control method of this embodiment is applied to the microwave air interface architecture of the embodiment shown in fig. 1, a corresponding air interface can be selected according to the service bearable state of the interference cancellation type PLA link topology to enter energy saving or exit energy saving, that is, the ODU power corresponding to the corresponding air interface can be selectively turned on or turned off according to the service bearable state of the interference cancellation type PLA link topology, so that the service resources in the interference cancellation type PLA link topology are saturated, that is, the service transmission can be performed by well adapting to the user traffic in the network, which can greatly avoid the surplus of the service resources in the link, and achieve the purpose of reasonably and effectively controlling the transmission resources of the microwave air interface, in particular, when the interference cancellation type PLA link topology with the XPIC or xpmimo function is running, the air interface of each PLA member receives non-own interference information The second trigger information and the adjacent hop information are used for eliminating interference, so that service resources in an interference cancellation type PLA link topology can reach lossless balance, and by sending the adjacent hop information, two ends of a selected air interface can synchronously enter an energy-saving state or exit the energy-saving state, so that an ODU power supply corresponding to the air interface can be correspondingly closed or opened, and the intelligent control of the ODU power supply corresponding to the air interface is realized.
In summary, the control method of this embodiment can reduce power waste caused by the interference cancellation type PLA link topology in service transmission, and as for the interference cancellation type PLA link topology as a whole, the purpose of stably controlling the air interface corresponding to the ODU power source can be achieved, so that energy-saving transmission of the air interface can be achieved.
Fig. 9A is a schematic view of a traffic flow direction of each air interface in an existing PLA link, where in a general case, the traffic flow direction in the PLA link is fixedly flowed into a corresponding data selector, that is, as shown in fig. 9A; fig. 9B is a schematic diagram of a service switching operation of an energy-saving air interface in a PLA link according to an embodiment of the present invention, and actually, by analyzing air interface control under each PLA link, it can be known how the air interface topology of the PLA link is, that is, whether the air interface topology of the PLA link belongs to a pure PLA link topology or an interference-cancellation type PLA link topology, as shown in fig. 9B, after the energy-saving air interface in the PLA link is determined, it is possible to switch the service traffic of the energy-saving air interface to other non-energy-saving air interfaces (that is, to implement control conversion from fig. 9A to fig. 9B), so as to ensure that the service of the energy-saving air interface is switched in a lossless or instantaneous interruption manner, that is, the remaining non-energy-saving air interfaces are used to share the service of the energy-saving air interface, thereby preventing service loss easily caused when the energy-saving air interface is switched, and ensuring that a user has stable and reliable network performance, to enhance the network experience of the user.
Correspondingly, when the energy-saving control is quitted, no matter what the air interface topology of the PLA link is, namely no matter what the air interface topology of the PLA link belongs to the pure PLA link topology or the interference cancellation type PLA link topology, after the air interface to be quitted in the PLA link is determined, the traffic load of the air interface can be recovered by switching the traffic of other air interfaces to the air interface, so that the service of the air interface to be saved can be recovered in a lossless or instantaneous interruption manner, namely the service of the air interface to be saved is recovered, and therefore, a user is ensured to have stable and reliable network service performance, and the network experience of the user is improved.
On the one hand, based on the consideration of pure PLA link topology, 10ms of delay is adopted, the first timer is started, and when the first timer is overtime, the specific operation of the ODU power supply corresponding to the empty port to be energy-saving is turned off, wherein the main functions of the delay operation and the first timer setting are to enable both the home terminal and the opposite terminal of the empty port to be energy-saving to enter an energy-saving state synchronously, so that the overall service of the empty port to be energy-saving can achieve energy-saving effect of millisecond-level interruption or no interruption, a good and stable service network can still be provided for a user during the energy-saving control, actually, the delay time can also adopt other specific parameters, and can be set specifically according to the structure of the empty port topology, the above embodiment does not strictly limit the specific value of the delay time, and similarly, in exiting the energy-saving control flow, the corresponding ODU power supply is turned on after 20ms of delay operation is adopted, the home terminal and the opposite terminal of the air interface to be saved with energy can synchronously exit the energy saving state, so that the whole service of the air interface to be saved with energy can obtain the energy saving effect of millisecond-level interruption or no interruption, and a good and stable service network can be still provided for the user in the process of executing exit energy saving control; on the other hand, based on the consideration of the interference cancellation type PLA link topology, silencing is performed after 10ms delay, a second timer is started, when the second timer is overtime, the specific operation of the ODU power supply corresponding to the air interface to be energy-saving is closed, and for energy-saving control of the interference cancellation type PLA link topology, the ODU power supply is silenced, so that large interference is prevented from being continuously generated between related polarization groups in the link, the air interface energy-saving control is more stable, and the overall service of the air interface to be energy-saving can easily obtain an energy-saving effect of millisecond-level interruption or no interruption.

As shown in fig. 11, firstly, energy saving policy information is obtained, then, an air interface to be energy saved is determined based on the energy saving policy information, and a locking operation is performed on the air interface to be energy saved, so that it is ensured that a PLA link service is lossless, and then, for an ODU power supply side corresponding to the air interface to be energy saved, an air interface topology type of the air interface needs to be judged, so that whether an opposite-end network element needs to be notified according to the air interface topology type is determined, and accordingly, two execution modes are determined, where one mode is to directly close the ODU power supply corresponding to the air interface to be energy saved without notifying the opposite-end network element, and the other mode is to notify the opposite-end network element, that is, to send adjacent hop information to the opposite-end network element, and perform delay and silence processing on the air interface to be energy saved, so that the ODU power supply corresponding to the two ends to be energy saved is finally closed.
