Description

Network equipment management method, device and communication system

Technical Field

The present application relates to the field of communication technology, and more particularly, to a network device management method, apparatus, and communication system.

Background

In a network architecture of a wireless local area network, an access device needs to use electric energy to work, and in general, the access device can obtain electric energy from a power plant, such as a power grid, to work, and when a power failure event occurs, the access device can obtain electric energy from a standby power supply to work. The backup power source is generally composed of a backup battery, and the backup battery configured by the access device is limited, that is, the access device is limited in duration by using the electric energy of the backup power source to perform work when power failure occurs.

Currently, when an access device cannot obtain electric energy from a power plant, the access device may take actions such as symbol off, carrier off, etc. to save electric energy consumption per unit time. However, such a management action in the non-power plant power supply state is insufficient to provide reliable service to the user over time or service range, such as may result in too short a service duration or too small a service range. Therefore, how to improve the service reliability in the scenario that the access device is in the non-power plant power supply state is a technical problem to be solved.

For clarity, some terms in the embodiments of the present application are explained below.

1. Network management

Network management refers to managing network resources, including but not limited to monitoring, controlling, and recording performance and usage of network resources, and issuing actions to network resources (e.g., devices in a network) based on detected network conditions to enable the network to operate efficiently. By way of example, network management may be monitoring, testing, configuring, analyzing, evaluating, controlling, etc., network resources. The network management can also report and process in time when the network fails, coordinate and maintain the high-efficiency operation of the network system, and the like. The network resource is a role object of network management, and may also be referred to as a network object or a managed object, and may be, for example, a network device, a base station device, a router, a switch, a core network device, or the like.

The network management may be performed by a Network MANAGEMENT SYSTEM (NMS) or an operation support system (operations support system, OSS), or by the NMS or OSS together with an Equipment MANAGEMENT SYSTEM (EMS), or by other network elements, functions, modules or devices having a network management function, which is not particularly limited in the present application.

2. Power supply system

A power system is a system that provides electrical power to an access device. The power supply system includes a utility power system, which is a system that supplies power in a power plant (e.g., a power grid) to the access device, and a backup power system, which is a system that supplies non-power plant power, i.e., reserve power, to the access device. In general, a backup power system generally stores electric energy using a battery, and a battery for storing electric energy is also called a backup battery. In general, when the utility power system works normally, the backup power system can not work, and when the utility power system stops working, namely, a power failure event occurs, the backup power system starts to work to provide backup power for the access equipment. One access device may be configured with a separate power system, or multiple access devices may share a single power system.

3. Access device

The access device may be a radio access network (radio access network, RAN) device, a node or device that accesses a terminal device to a wireless network, including but not limited to: a base station, a next generation node B (gNB) in 5G, an evolved node B (eNB), a radio network controller (radio network controller, RNC), a Node B (NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (e.g., home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmit point (TRANSMITTING AND RECEIVING point, TRP), a transmit point (TRANSMITTING POINT, TP), and/or a mobile switching center, etc. Or the access network device may also be at least one of a centralized unit (centralized unit, CU), a Distributed Unit (DU), a centralized control plane (CU-CP) node, a centralized user plane (CU-UP) node, an access backhaul (IAB) integrated (INTEGRATED ACCESS AND), or a radio controller in a cloud radio access network (cloud radio access network, CRAN) scenario, etc. Or the access network device may be a relay station, an access point, a vehicle-mounted device, a terminal device, a wearable device, an access network device in a 5G network or an access device in a future evolved public land mobile network (public land mobile network, PLMN), etc.

In the technical scheme provided by the application, the device for realizing the function of the access equipment is the access equipment, and the technical scheme provided by the application is described.

The related terms related to the embodiment of the present application are described above, and an application scenario to which the embodiment of the present application is applicable is described below with reference to fig. 1.

The communication system suitable for the embodiment of the application mainly comprises a system for network management, and a managed access device and a power supply system. Referring to fig. 1, the systems in which network management is performed are NMS and EMS, such as NMS 110, EMS 121 and EMS 122 in (a) of fig. 1. NMS 110 may communicate with EMS 121 and EMS 122, respectively. NMS 110 and EMS 121 may collectively manage access device 131 and access device 132, and NMS 110 and EMS 122 may collectively manage access device 133 and access device 134. Access device 131 is configured with power system 141, access device 132 is configured with power system 142, and access device 133 and access device 134 share power in power system 143.

Referring to fig. 2, the system in which network management is performed is an NMS, for example, NMS 210 in fig. 2, and NMS 210 may directly manage access device 221, access device 222, access device 223, and access device 224. The access device 221 is configured with a power supply system 231, the access device 222 is configured with a power supply system 232, and the access device 223 and the access device 224 share power in the power supply system 233.

It should be noted that the NMS in the embodiment of the present application may also be replaced by an operation support system (operations support system, OSS).

It should be further noted that, the solution of the present application may also be applied to other communication systems including corresponding devices, and the present application is not limited thereto, and embodiments of the present application are not limited thereto specifically.

Currently, if an access device experiences a power outage event, the access device will operate using the power stored in the backup battery. Because of the limited power stored in the battery backup, the access device may take some power saving measures (e.g., symbol off, etc.) to increase the operating time in the power outage state. However, such a management action in the non-power plant power supply state is insufficient to provide reliable service to the user over time or service range, such as may result in too short a service duration or too small a service range.

The application provides a method, a device and a communication system for managing network equipment, wherein when first access equipment is in a non-power-plant power supply state, a first network equipment management device acquires the residual non-power-plant power supply time length of the first access equipment and the power supply condition of second access equipment adjacent to the first access equipment, and adjusts the service coverage capacity of the first access equipment based on the power supply information of the two access equipment, for example, reduces or increases the service coverage capacity of the first access equipment, so that the access equipment provides reasonable power supply time length or coverage service range for users, and the service reliability is improved. The method of network device management is further described below in conjunction with fig. 3-8.

S310, the first network equipment management device acquires the first power supply information and the second power supply information.

The first power supply information indicates that the first access device is in a non-power plant power supply state and a remaining non-power plant power supply duration, and the second power supply information indicates that the second access device is in a power plant power supply state or indicates that the second access device is in a non-power plant power supply state and a remaining non-power plant power supply duration, and a maximum service coverage area of the second access device overlaps with a maximum service coverage area of the first access device and a maximum service coverage area of the second access device.

In the embodiment of the present application, the first network device management apparatus may refer to the NMS 110 described in fig. 1, which may manage a plurality of access devices through the EMS, or the first network device management apparatus may refer to the NMS 210 described in fig. 2, which may directly manage a plurality of access devices. Or the first network device management apparatus may be the EMS in fig. 1 or 2, and may directly manage the plurality of access devices.

The first access device may be any of the access devices described in fig. 1. The first access device being in a non-power plant power state means: the first access device cannot obtain the electric energy continuously generated by the power plant, or the first access device cannot obtain the electric energy from the power grid. Correspondingly, in the power plant power supply state means: the continuously generated electrical energy of the power plant, or electrical energy from the electrical grid, can be obtained. In the present application, the state of being in a non-power plant power supply may be expressed as being in a power outage state, and the state of being in a power plant power supply may be expressed as not being in a power outage state.

The second access device may be an access device configured with a neighbor relation to the first access device. The second access device may be in a non-power plant powered state or may be in a power plant powered state.

It should be noted that, in the embodiment of the present application, the second access device refers to a neighboring network device of the first access device, so that the number of second access devices may be one or more, and when the number of second access devices is multiple, the multiple access devices may be in a non-power-plant power-supply state, or none of the multiple access devices may be in a non-power-plant power-supply state, or some of the multiple access devices are in a non-power-plant power-supply state. For convenience of description, in the embodiment of the present application, description will be made later with a second access device.

The first power supply information indicates that the first access device is in a non-power plant state and a remaining non-power plant power supply duration, wherein the remaining non-power plant power supply duration refers to: the maximum length of time that can be supported for operation using the remaining power provided by the non-power plant is related to the operating current of the access device and the amount of power that can be provided by the non-power plant, e.g., the non-power plant power period may be equal to the amount of power that can be provided by the non-power plant divided by the operating current. It may be appreciated that the remaining non-power plant power supply duration indicated by the first power supply information may be a maximum duration that the first access device can support when in the current working state, that is, in the current working current and non-power plant power supply configuration state.

The first power supply information may include at least one of: information indicating that the first access device is in a non-power plant power state, non-power plant power information remaining by the first access device, operating current information of the first access device, or battery parameter information of the first access device for storing non-power plant power.

For example, the non-power plant power information may indicate a power level that the non-power plant is capable of providing, such as a total remaining power of the backup power system backup battery in the power system of the first access device, and the remaining power level may be represented by an absolute value (e.g., 100 milliampere hours) or a relative value (e.g., percentage remaining). The operating current information indicates an operating current output by a non-power plant (e.g., backup power system) for the first access device, or a backup battery load current, an output current, etc. The standby battery parameter information indicates standby battery parameters, and the standby battery parameters may include parameters such as rated current, rated capacity, battery model and the like of the standby battery.

It will be appreciated that the first power supply information may also directly include the remaining non-power plant power supply duration, or the first power supply information indicates information that can be used to determine the remaining non-power plant power supply duration, which is not particularly limited by the present application.

If the second access device is in the power plant power supply state, the second power supply information indicates that the second access device is in the power plant power supply state, and if the second access device is in the non-power plant power supply state, the second power supply information is similar to the description of the first power supply information, and will not be repeated here.

The first power supply information and the second power supply information are described above, and how the first network device management apparatus obtains the first power supply information and the second power supply information is described below with reference to fig. 4.

Mode a:

In the mode a, the first network device management apparatus may be an NMS, the second network device management apparatus may be an EMS, and the first network device management apparatus acquires the first power supply information and the second power supply information through the second network device management apparatus.

S311a, the first access device sends the first power supply information to the second network device management apparatus, and correspondingly, the second network device receives the first power supply information from the first access device.

The second network device management apparatus may actively detect whether the first access device is in a non-power plant power supply state, for example, actively detect what power supply mode is adopted by the first access device, or detect what working state is adopted by the power supply system of the first access device through the first access device, or the first access device or the power supply system of the first access device may trigger to actively report to the second network device management apparatus based on a power failure event.

For example, the second network device management apparatus may periodically send query information to the first access device, and the first access device may send information indicating a power supply mode to the second network device management apparatus in response to the query information, or the first access device may be configured to periodically report information indicating a power supply mode to the second network device management apparatus, for example, which power supply mode is one of mains power supply and backup power system power supply. If the first access device sends a power supply mode indicating that the power supply mode is to supply power to the standby power system to the second network device management apparatus, the second network device management apparatus may mark the first access device as a power-off first access device.

Further exemplary, the first access device may send information indicating that the backup power system power mode is adopted to the second network device management apparatus based on the power outage event trigger, and the second network device management apparatus marks the first access device as the first access device with power outage. For example, the first access device or a power system of the first access device may set a power outage alarm mechanism, and when a power outage event is sent, the first access device sends information indicating that the standby power system power supply mode is adopted to the second network device management apparatus based on alarm triggering.

When the first access device reports to the second network device management apparatus that the first access device is in a non-power-plant power supply state, the first power supply information indicates a remaining non-power-plant power supply duration. Optionally, the first access device may further report, to the second network device management apparatus, a start time when the power supply state of the non-power plant is in a power supply state, for example, the first access device may report a start time when a battery in the standby power system starts to supply power. Optionally, the first power supply information further indicates a starting time when the first access device is in a non-power plant power supply state.

Optionally, the first power supply information further indicates an identification of a neighboring access device of the first access device.

S312a, the second access device sends second power supply information to the second network device management apparatus, and correspondingly, the second network device receives the second power supply information from the second access device.

The manner in which the second access device sends the second power supply information to the second network device management apparatus is similar to the manner in which the first access device sends the second power supply information to the second network device management apparatus in S311a, and will not be described herein. It is understood that when the second access device is in the power plant power supply state, the second power supply information does not include information indicating a remaining non-power plant power supply duration of the second access device.

It should be noted that if the first power supply information further indicates the identity of a second access device adjacent to the first access device, the second access device may query the second access device for the second power supply information. The second network device management apparatus may determine the second access device adjacent to the first access device if the first power supply information does not indicate the identity of the second access device adjacent to the first access device, for example, the second network device management apparatus may identify the adjacent second access device by identifying the adjacent cell through the same-frequency neighbor MR report number, or identifying the overlapping second access device and cell through an automatic neighbor relation, or identifying the overlapping second access device and cell through the coverage area of the first access device, etc., which is not particularly limited in the present application.

S313a, the second network device management apparatus transmits the first power supply information and the second power supply information to the first network device management apparatus, and correspondingly, the first network device management apparatus receives the first power supply information and the second power supply information from the second network device management apparatus.

For example, the second network device management apparatus may directly transmit the first power supply information and the second power supply information to the first network device management apparatus. Or the second network device management apparatus may process the first power supply information and the second power supply information and then send the processed first power supply information and the second power supply information to the first network device management apparatus, where, for example, the second network device management apparatus may generate an identifier list of the access device and a corresponding event type, where the event type is used to mark whether the access device is in a power plant power supply state or a non-power plant power supply state, and a remaining non-power plant power supply duration of the access device in the non-power plant power supply state.

Mode b:

In the mode b, the first network device management apparatus may be an NMS, and the first network device management apparatus may directly acquire the first power supply information and the second power supply information. Or the first network device management apparatus may be an EMS in case the EMS determines to adjust the service coverage capability of the access device.

S311b, the first access device sends the first power supply information to the first network device management apparatus, and correspondingly, the first network device receives the first power supply information from the first access device.

The manner in which the first access device sends the first power supply information to the first network device management apparatus is similar to the manner in which the first access device sends the first power supply information to the second network device management apparatus described in step S311a, and will not be described herein.

S312b, the second access device sends the second power supply information to the first network device management apparatus, and correspondingly, the first network device receives the second power supply information from the second access device.

The manner in which the second access device sends the second power supply information to the first network device management apparatus is similar to the manner in which the second access device sends the second power supply information to the second network device management apparatus described in step S312a, and will not be described herein.

It should be noted that, when the first network device management apparatus is described to obtain the first power supply information and the second power supply information through the second network device management apparatus, and the first network device management apparatus directly obtains the first power supply information and the second power supply information, the description is made by using the first access device having an independent power supply system, that is, the power and the current of the power supply system for providing the first access device with the non-power-plant electric energy are determined. In one possible implementation, the first access device does not have a separate power supply system, or the amount and current of the power supply system providing non-power plant power to the first access device is uncertain, the first network device management apparatus may receive centralized standby power supply information from the power supply system, the power supply system is configured to provide reserve power for a plurality of access devices including the first access device, the centralized standby power supply information may indicate a duration range of non-power plant power supply durations that can be provided for the first access device, and the first network device management apparatus may determine a remaining non-power plant power supply duration of the first access device based on the centralized standby power supply information. For example, the concentrated backup power supply information indicates a range of proportions of the concentrated backup battery output current that the first access device is currently capable of using, such as, for example, the first access device is capable of using at most 30% of the concentrated backup battery output current. A specific implementation manner in which the first access device does not have an independent power supply system may refer to the description of fig. 7, which is not repeated herein.

In addition, when the second access device is not in the outage state, the first network device management apparatus may also determine that the second access device is in the outage state. For example, the first network device management apparatus does not receive information indicating that the second access device has failed, and the first network management apparatus may determine that the second access device is capable of harvesting power from the power plant.

S320, the first network device management apparatus adjusts the service coverage capability of the first access device based on the first power supply information and the second power supply information, and optionally adjusts the service coverage capability of the second access device.

The first network device management means may learn a maximum service coverage area of the first access device and a maximum service coverage area of the second access device. The first network device management means may adjust the service coverage area and/or the service coverage quality of the first access device according to the first power supply information and the second power supply information. Optionally, the first network device management means may also adjust the service coverage area and/or the quality of service coverage of the second access device. The first network device management apparatus adjusts the service coverage area, or adjusts the service coverage intensity, or adjusts the service coverage area and the service coverage quality synchronously, which may be related to the service scenario and the service requirement, for example, if the service of a certain area needs a higher signal intensity, the first network device management apparatus may keep the service coverage intensity of the area in a higher range when making a policy.

In one possible implementation, if the second access device is in a power plant power state, the first network device management means may adjust down the service coverage capability of the first access device, optionally adjust up the service coverage capability of the second access device. That is, since the power of the second access device is relatively sufficient, the first network device management apparatus may make the second access device bear a higher service pressure as much as possible, so that the power consumption of the first access device is reduced, and the working time in the power failure state is prolonged.

In another possible implementation, if the second access device is in a non-power plant power supply state, the first network device management apparatus may adjust the service coverage capability of the first access device and optionally the service coverage capability of the second access device according to the remaining non-power plant power supply duration of the first access device and the remaining non-power plant power supply duration of the second access device. For example, the first network device management apparatus may adjust up the service coverage capability of the access device with a longer remaining non-power plant power supply duration, and adjust down the service coverage capability of the access device with a shorter remaining non-power plant power supply duration. Or when the remaining non-power plant power supply time length of the access equipment is longer than a preset threshold value, the first network equipment management device increases the service coverage capacity of the access equipment, and when the remaining non-power plant power supply time length of the access equipment is smaller than or equal to the preset threshold value, the first network equipment management device decreases the service coverage capacity of the network equipment. When the first network device management apparatus adjusts the service coverage capability, the remaining non-power plant power supply duration of the first access device and the second access device can be comprehensively considered, so that the first access device and the second access device can continuously work in a power failure state.

The first network device management means adjusts the service coverage capabilities of the access device in at least one of the following ways, each of which may be considered as the access device performing a coverage adjustment action:

and (3) a step of: adjusting the transmission mode of the synchronous signal blocks (synchronization signal block, SSB);

And II: adjusting the angle of the antenna;

Thirdly,: adjusting transmission power;

fourth, the method comprises the following steps: the list of overlay shapes is adjusted.

Adjusting the SSB transmission mode of the access device may include adjusting the number of SSB beams of the access device, e.g., if the service coverage capability of the access device is to be reduced, the number of SSB beams of the access device may be reduced, and if the service coverage capability of the access device is to be increased, the number of SSB beams of the access device may be increased. Adjusting the SSB transmission scheme of the access device may further include adjusting the SSB period of the access device, e.g., if the service coverage capability of the access device is to be reduced, the SSB period of the access device may be increased, and if the service coverage capability of the access device is to be increased, the SSB period of the access device may be reduced.

Adjusting the antenna angle of the access device may include adjusting the antenna's tilt up-down capability, e.g., if the access device's service coverage capability is to be reduced, the antenna's tilt up-down capability may be reduced, and if the access device's service coverage capability is to be increased, the antenna's tilt up-down capability may be increased. Adjusting the antenna angle of the access device may also include adjusting a horizontal azimuth of the antenna, e.g., if the service coverage capability of the access device is to be reduced, the horizontal azimuth capability of the antenna may be reduced, and if the service coverage capability of the access device is to be increased, the horizontal azimuth capability of the antenna may be increased.

Adjusting the transmission power of the access device may include adjusting the transmission power at which the access device transmits downlink data, e.g., the transmission power may be reduced if the service coverage capability of the access device is to be reduced, and the transmission power may be transmitted if the service coverage capability of the access device is to be increased. The network device management means may adjust the configuration in the coverage shape list to adjust the service coverage capabilities of the access device.

It should be noted that, the network device management apparatus may select one or more of the above-mentioned coverage adjustment actions by integrating the service scenario and the standby power situation of the access device, for example, if the network device management apparatus determines to reduce the service coverage capability of the power outage access device, the network device management apparatus may determine to reduce the coverage adjustment actions of one or more of reducing the service coverage capability, such as reducing the SSB beam number of the power outage access device, reducing the tilt up and tilt down capability of the antenna of the power outage access device, and the like.

It should be further noted that, the first network device management apparatus may adjust the service coverage capability of the access device with a granularity of a cell, and the coverage adjustment may be performed with the granularity of the cell.

The manner in which the first network device management apparatus adjusts the service coverage capability of the access device is described above, and similar to the step S310, the first network device management apparatus may directly adjust the service coverage capability of the access device, or may also adjust the service coverage capability of the access device through the second network device management apparatus, which is described below in connection with fig. 5.

Illustratively, the coverage adjustment indication information #1 includes a coverage adjustment action list of the first access device and a coverage adjustment action list of the second access device, such as the coverage adjustment action list of the access device includes at least one of the following parameters: the identification, the number of SSB beams, the SSB period, the antenna upper and lower dip angle range, the antenna horizontal azimuth angle range, the downlink transmission power range and the coverage shape list.

Alternatively a323A, the second network device management means adjusts the service coverage capability of the second access device based on the coverage adjustment instruction information # 1.

The second network device management apparatus may be configured to send information indicating a second coverage adjustment action to the second access device, the second access device performing the second coverage adjustment action to adjust the service coverage capability of the second access device.

Mode B:

In mode B, the first network device management apparatus may be an NMS, and the first network device management apparatus may directly acquire the first power supply information and the second power supply information. Or the first network device management apparatus may be an EMS in case the EMS determines to adjust the service coverage capability of the access device.

S321B, the first network device management apparatus transmits the coverage adjustment instruction information #2 to the first access device.

The coverage adjustment indication information #2 indicates that the first access device adjusts the service coverage capability of the first access device.

Illustratively, the coverage adjustment indication information #2 instructs the first access device to perform a first coverage adjustment action that the first access device performs to adjust the service coverage capability of the first access device.

S322B, the first access device adjusts the service coverage capability of the first access device based on the coverage adjustment indication information # 2.

The first access device performs a first coverage adjustment action to adjust service coverage capabilities of the first access device.

Alternatively, S323B, the first network device management apparatus transmits the coverage adjustment instruction information #3 to the second access device.

The coverage adjustment indication information #3 indicates that the second access device adjusts the service coverage capability of the second access device.

Illustratively, the coverage adjustment indication information #3 instructs the second access device to perform a second coverage adjustment action that the second access device performs to adjust the service coverage capability of the second access device.

Optionally, S324B, the second access device adjusts the service coverage capability of the second access device based on the coverage adjustment indication information # 3.

The second access device performs a second coverage adjustment action to adjust the service coverage capabilities of the second access device.

The method of network device management by the network device management apparatus is described above, and in order to facilitate understanding of the embodiments of the present application, possible implementation manners of network device management are described below by taking EMS and NMS as examples in connection with fig. 6 to 8.

Fig. 6 is a schematic flow chart diagram of one implementation of an NMS for adjusting service coverage capability through an EMS according to an embodiment of the present application.

S601, the EMS acquires first power supply information and second power supply information.

This step may refer to step S310 in fig. 3 and the description of mode a in fig. 4, and will not be described here.

S602, the EMS sends the first power supply information and the second power supply information to the NMS.

S603, the NMS transmits the overlay adjustment instruction information #1 to the EMS.

This step may refer to step S320 in fig. 3 and the description of mode a in fig. 4, which are not repeated here.

Optionally, the EMS determines a power saving policy S604.

The EMS may further adjust the power saving capability of the first access device, and optionally, may also adjust the power saving capability of the second access device. The power saving policy instructs the first access device to perform a first power saving action and the second access device to perform a second power saving action.

The first power saving function is to reduce the power consumption of the first access device. The first power saving action may include at least one of the following actions: the symbol turn-off, the carrier turn-off, the channel turn-off, the sleep turn-on, the chip turn-off, the power turn-on or the power reduction are turned on. The symbol turn-off may refer to a power-saving action of turning off a power amplifier of the radio frequency module in real time to reduce energy consumption when the access device detects that the downlink symbol does not bear data; the carrier turn-off may be that the carrier is in a turn-off state, and if the power amplifier of the radio frequency module where the turned-off carrier is located has no other carrier in a working state, the power amplifier of the radio frequency module is turned off, so as to achieve the purpose of energy saving and energy saving action; the channel turn-off can be to turn off part of the radio frequency channels within a set time, so that the power consumption of the radio frequency equipment is reduced, and energy-saving action of energy conservation is realized. Sleep may refer to an access device entering a low power consumption state of operation. Chip off may refer to turning off certain specific chips, and power off may refer to turning off part of the power.

Different combinations of the plurality of power saving actions can form different power saving strategies, and the different power saving strategies can be applied to different power saving scenes corresponding to different power saving levels. The EMS may be configured with information corresponding to the power saving policy and the power saving action, such as a mapping table of the node policy identifier and the power saving action identifier, so that the EMS may look up a table according to different power saving requirements to determine the power saving action performed by the access device. To facilitate understanding of the embodiments of the present application, one example of the correspondence information of the power saving strategy and the power saving action is shown in table 1 below.

Table 1:

the energy saving levels can be classified into different levels based on the energy that can be saved, for example, energy saving level 1 represents low intensity energy saving, energy saving level 2 represents medium intensity energy saving, and energy saving level 3 represents high intensity energy saving.

It should be noted that, the EMS may adjust power consumption of the access device with a granularity of a cell, and the power saving action may be performed with the granularity of the cell.

The EMS may determine a power saving action based on the standby power duration. The standby time length refers to the total time length of the access equipment estimated to be powered by the standby system, namely the time length of power failure of the access equipment. For example, if the standby power duration is shorter than or equal to the preset threshold, the EMS selects the power saving policy 2 in table 1, and the corresponding power saving action is symbol off, so as to reduce the influence of the power saving action on the network performance. If the standby power duration is longer than the preset threshold value, the EMS selects a power saving strategy 3, and the corresponding power saving actions are turning on the symbol off and the carrier off so as to increase the working duration of the access equipment depending on the standby power system for power supply.

Optionally, the EMS determines the first power saving action according to the standby power duration and the first power supply information of the first access device. The first power supply information indicates a remaining non-power-plant power supply duration, and if the remaining non-power-plant power supply duration is longer than a preset remaining non-power-plant power supply duration threshold, the EMS selects the power saving strategy 2 if the standby power duration is shorter than or equal to a preset threshold, and if the standby power duration is longer than the preset threshold, the EMS selects the power saving strategy 3. Under the condition that the residual non-power plant power supply duration is shorter than or equal to a preset residual non-power plant power supply duration threshold, if the standby power duration is shorter than or equal to a preset threshold, the EMS selects the power saving strategy 3, and if the standby power duration is longer than the preset threshold, the EMS selects the power saving strategy 1.

Optionally, the EMS determines the first power saving action according to the standby power duration and the coverage adjustment indication information # 1. For example, the EMS determines that the first power saving operation is performed according to the standby power duration and the coverage adjustment indication information #1 (for example, the number of SSB beams), if the standby power duration is shorter than or equal to a preset threshold value in the case that the number of SSB beams is greater than a preset SSB beam number threshold, the EMS selects the power saving policy 2, and if the standby power duration is longer than the preset threshold value, the EMS selects the power saving policy 3. Under the condition that the number of SSB beams is smaller than or equal to a preset SSB beam number threshold, if the standby power duration is shorter than or equal to a preset threshold, the EMS selects the power saving strategy 3, and if the standby power duration is longer than the preset threshold, the EMS selects the power saving strategy 1.

Optionally, different standby battery parameters (e.g., different battery types: lithium battery, lead-acid battery) correspond to different node policy identifications and power saving action identifications. The EMS may query the corresponding mapping table.

If the second access device is also in the power outage state, the EMS may determine a second power saving action based on the second power supply information and the coverage adjustment indication information # 1. The manner in which the EMS determines the second power saving operation is similar to the manner in which the first power saving operation is determined as described above, and will not be described again.

It should be noted that the standby power durations of the first access device and the second access device may be the same or different, and the network device management apparatus may also consider the standby power duration of one access device while determining the power saving action of the other access device, so that the two access devices can continuously work in the corresponding standby power durations.

S605, the EMS sends first indication information to the first access equipment.

The first indication information is used for indicating the first access device to execute a first coverage adjustment action. Optionally, if the EMS further determines a power saving policy, the power saving policy instructs the second access device to perform the first power saving operation, and the first instruction information further instructs the second access device to perform the first power saving operation. The description of the coverage adjustment action may refer to the description of step S320 in fig. 3.

The first indication information may directly indicate the first access device to perform the first coverage adjustment action, for example, the information may include parameters corresponding to the first coverage adjustment action, such as the SSB beam number, etc. The information indicating the first coverage adjustment action may also indirectly indicate that the first access device performs the first coverage adjustment action, such as the information including an identification of the first coverage adjustment action, etc.

It should be noted that, the information indicating the first coverage adjustment action and the information indicating the first power saving action may be carried and transmitted in one message, for example, as one or more cells in one message, or may be respectively transmitted in a plurality of messages, for example, the information indicating the first coverage adjustment action and the information indicating the first power saving action may be respectively transmitted in two messages, which is not particularly limited in the present application.

S606, the first access device performs a first action.

The second action includes a second coverage adjustment action to adjust service coverage capabilities of the second access device. Optionally, the second action further comprises a second power saving action to adjust the power consumption capability of the second access device.

Optionally, S607, the EMS sends second indication information to the second access device.

The second indication information is for instructing the second access device to perform a second coverage adjustment action. Optionally, if the EMS further determines a power saving policy, the power saving policy instructs the second access device to perform a second power saving action, and the second instruction information further instructs the second access device to perform the second power saving action. The description of the coverage adjustment action may refer to the description of step S320 in fig. 3.

Optionally, S608, the second access device performs a second action.

Fig. 6 illustrates an implementation of the NMS to adjust service coverage capability through the EMS, in a possible implementation, the first access device does not have an independent power system, that is, the reserve power of the first access device mentioned in step S310 in fig. 3 is not a certain amount, and the network device management apparatus may receive centralized reserve power information from the power system for providing the reserve power for the plurality of access devices including the first access device, and an implementation of the power system of the first access device as a shared power system is described below with reference to fig. 7.

Fig. 7 is a schematic flowchart of a method for coverage adjustment when a power system of a first access device is a shared power system according to an embodiment of the present application.

S701, the power supply system transmits the centralized power supply information to the NMS, and the NMS receives the centralized power supply information from the power supply system and acquires the first power supply information and the second power supply information.

The power supply system is used for providing non-power plant electric energy for the plurality of access devices, and the centralized power supply information indicates a duration range of non-power plant power supply duration which can be provided for the first access device by the power supply system.

The first access device and other access devices share a power supply system, i.e. the power of the standby battery in the power supply system can be supplied to the first access device for use or can be supplied to other access devices for use. The centralized standby power supply information may indicate a duration range of non-power plant power supply durations that may be provided for the first access device, and the NMS may determine a remaining non-power plant power supply duration of the first access device based on the centralized standby power supply information.

Optionally, the centralized power supply information indicates a duration range in which the power supply system is able to provide the remaining standby power duration for the first access device. Illustratively, the centralized power supply information indicates at least one of: the power supply of the access equipment is in a ratio, the residual capacity of the concentrated standby battery and the parameters of the concentrated standby battery are included, the residual capacity of the concentrated standby battery comprises the total residual capacity of the standby battery in the power supply system, and the parameters of the concentrated standby battery can comprise the output current of the standby battery, and can also comprise the parameters of rated capacity, battery model and the like. Further, the NMS can determine a duration range of remaining standby durations of the first access device according to the content in the centralized power information.

Optionally, the centralized standby power supply information includes a ratio range of the centralized standby battery power that can be used by a portion of the access devices (such as the first access device and the access device adjacent to the first access device) powered by the power supply system, or includes a ratio range of the centralized standby battery power that can be used by all the access devices powered by the power supply system, which is not particularly limited in the present application.

The NMS may determine a remaining non-power plant power duration of the first access device based on the centralized power supply information.

Illustratively, the NMS is based on the centralized power information and the standby power duration of the first access device, and the remaining non-power plant power duration of the first access device. For example, if the standby time period is less than or equal to the standby time period threshold, the NMS may adjust the operating current of the first access device, such as adjusting the current range supplied by the power system to the first access device from 5A to 6A to the current range 7A to 8A.

It should be noted that, in this embodiment, the NMS may determine that the first access device is in the non-power-plant power supply state in the manner described in step S310 in fig. 3, and determine the remaining non-power-plant power supply duration of the first access device in the manner described in step S701. That is, in this embodiment, the first power supply information may include information indicating that the first access device is in a non-power plant power supply state, and information indicating a remaining non-power plant power supply period of the first access device, which the NMS may acquire from different devices, respectively. The second power supply information is similar to the first power supply information, and if the second access device is in the power plant power supply state, the NMS may acquire the second power supply information in the manner as described in step S310 in fig. 3. If the second access device is in a non-power plant power supply state, the second access device and the first access device share the power supply system, and the NMS may acquire the second power supply information in the manner described above, which is not described herein.

S702, the NMS sends standby power adjustment information to the power supply system.

The standby power adjustment information indicates a battery level that the first access device is capable of using. For example, the standby power adjustment information includes a current supplied by the power supply system to the first access device, or a proportion of the amount of concentrated standby power battery that the first access device can use. Optionally, if the access device powered by the power supply system further includes a neighboring second access device of the first access device, the standby power adjustment information further indicates a battery level that the neighboring second access device can use.

It will be appreciated that if the battery level available to other access devices is also adjusted, such as when the battery level available to the first access device is adjusted up, the battery level available to other access devices may be appropriately adjusted down in order to ensure that the total power does not exceed a maximum limit.

It should be noted that, in this embodiment, since the remaining non-power plant power supply duration of the access device can be adjusted, the NMS may comprehensively determine the standby power adjustment information and adjust the service coverage capability of the access device according to the usage scenario, for example, when the NMS adjusts the coverage service capability of the first access device, if the battery power that can be used by the first access device is adjusted to be high, the magnitude of the coverage service capability may be appropriately adjusted, which is not particularly limited by the present application.

The power supply system may adjust the amount of battery power that the access device is able to use based on the backup power adjustment information. Illustratively, the standby power adjustment information indicates a range of supply current adjusted by the plurality of access devices, and the power supply system adjusts the current output accordingly.

S703, the NMS transmits the overlay adjustment instruction information #1 to the EMS.

Optionally, the EMS determines a power saving policy S704.

This step may refer to the description of step S604 in fig. 6, and will not be described here.

S705, the EMS sends first indication information to the first access device.

This step may refer to the description of step S605 in fig. 6, and will not be described here.

Optionally, S708, the second access device performs a second action.

This step may refer to the description of step S608 in fig. 6, and will not be described here.

Fig. 6 and 7 above are each illustrated with NMS adjusting service coverage capability through EMS. In one possible implementation, the NMS may directly adjust the service coverage capability or the EMS determines how to adjust the service coverage capability. The NMS direct adjustment of service coverage capability is clear from the description of fig. 3 to 5. An implementation of how the EMS determines how to adjust the service coverage capability is described below in connection with fig. 8.

Fig. 8 is a schematic flow chart of a method for determining an overlay adjustment action by an EMS according to an embodiment of the present application.

Optionally, S801, the NMS transmits coverage adjustment policy indication information to the EMS.

The coverage adjustment policy indication information indicates a manner in which the EMS adjusts the service coverage capability. That is, in the embodiment shown in fig. 8, the NMS may inform the EMS of the manner of adjusting the service coverage capability without acquiring the first power supply information and the second power supply information, and the EMS adjusts the service coverage capability. For example, the NMS may send a preset threshold value, an optional coverage adjustment action, a value available for the number of SSB beams, a value available for an antenna angle, a value available for transmission power, or the like, used in adjusting the service coverage capability to the EMS, and the EMS adjusts the service coverage capability according to the first power supply information and the second power supply information.
