Detailed ways

It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

An embodiment of the present invention provides an energy-saving method based on positioning equipment. Refer to FIG. 1 , which is a schematic flow chart of a first embodiment of an energy-saving method based on positioning equipment of the present invention.

The energy-saving method based on positioning devices is applied to the UWB management platform, including the following steps:

Step S10: After obtaining positioning tag information of multiple ultra-wideband UWB base stations, determine the current coverage area of each UWB base station.

It should be noted that the execution subject of this embodiment is the UWB management platform in the energy-saving system based on positioning equipment. The energy-saving system based on positioning equipment includes the UWB management platform and BBU. In the 5G and UWB integration scenario, the energy-saving system based on positioning equipment constitutes The energy-saving system is shown in Figure 2. In addition to the BBU and UWB management platform, it also includes multiple UWB base stations, pRRUs, and expansion units EU. Among them, BBU, 5G core network, EU (Extended Unit, expansion unit), and pRRU are 5G network elements, and UWB base stations, UWB management platforms, and positioning servers are network elements of the UWB high-precision positioning system. The UWB base station is hung on the pRRU through the Ethernet electrical port. The EU supplies power to the pRRU through the optical-electric hybrid cable. The pRRU supplies power to the UWB base station through the POE module. The UWB management platform is connected to the back side of the BBU through the backhaul network. At the same time, pRRU, EU, The BBU also forms a transmission network to provide data forwarding functions for UWB base stations and UWB management platforms.

It is understandable that due to the consideration of transmission and radio frequency resource sharing, the industry has now derived a variety of combination solutions of 5G and other wireless networks, including short-range IoT, Bluetooth, WLAN, UWB, and zigbee, as shown in Figure 3. However, in the existing solution, 5G fronthaul works independently from the usual UWB. 5G fronthaul only provides data forwarding and POE power supply functions for UWB. The working status of BBU, RRU, UWB base station and other equipment is not comprehensively considered to achieve energy saving. To maximize efficiency, this embodiment provides a method that can integrate relevant information of 5G BBU, UWB base station and its UWB management platform, and provide an optimized control scheme to achieve overall energy saving.

In a specific implementation, the positioning tag information includes but is not limited to the basic information of the positioning tag such as the number of positioning tags and the status of the positioning tag. Each UWB base station can detect the positioning tags within the currently detectable area, thereby obtaining the currently detectable positioning tag information. Positioning tag information within the detected area, and each UWB base station can send the positioning tag information to the UWB management platform.

It should be noted that there can be multiple UWB base stations within the currently manageable area of the UWB management platform. The UWB management platform obtains the positioning tag information detected by each UWB base station within the currently manageable area, and determines the positioning tag information of each UWB base station. The three-dimensional position of the UWB base station and the area range that each UWB base station can currently detect. The area range that each UWB base station can currently detect is the current coverage area of each UWB base station. The current manageable area range of the UWB management platform is the current management area of the UWB management platform.

It can be understood that in order to ensure the security of the UWB management platform when performing base station management, the access request of the UWB base station needs to be verified. Furthermore, when the positioning tag information of multiple ultra-wideband UWB base stations is obtained, Before determining the current coverage area of each UWB base station, it also includes: when receiving an access request from each UWB base station, determining the base station basic information of each UWB base station; determining whether to respond to the access request of each UWB base station based on the base station basic information of each UWB base station. Incoming request; when determining to respond to the access request of each UWB base station, obtain the positioning tag information of each UWB base station.

In the specific implementation, each base station determines the URL address of its corresponding UWB management platform based on the information carried in the variable option field in the DHCP message, and initiates an access request to the UWB management platform based on the URL address. The UWB management platform obtains the initiated Basic base station information of the UWB base station requested for access. The basic base station information includes but is not limited to the product model and product serial number of the UWB base station.

It should be noted that the UWB management platform performs information verification based on the base station basic information of the UWB base station. The verification method may be to determine whether the base station basic information of each UWB base station matches the pre-stored basic information. If it matches, it means that the UWB base station has access. At this time, in response to the access request of the UWB base station, other verification methods may also be used, which is not limited in this embodiment.

It can be understood that when determining to respond to the access request of each UWB base station, each UWB base station is added to the work list, and the three-dimensional position of each UWB base station is determined through manual configuration or automatic matching.

Step S20: Determine the working status of each UWB base station based on the positioning tag information and current coverage area of each UWB base station.

It should be noted that the working state includes two types: power-on state and power-off state. The UWB management platform can determine which UWB base stations need to be turned on and which UWB base stations should be turned off in the current management area based on the positioning tag information and current coverage area of each UWB base station. The working status of the UWB base stations that need to be turned on is the power-on state, and those that need to be turned off are The working state of the UWB base station is the power-off state.

Step S30: Send the working status, bandwidth requirement and MAC address of each UWB base station to the indoor baseband processing unit BBU, and use the BBU to process each UWB base station and the corresponding data of each UWB base station according to the working status, bandwidth requirement and MAC address of each UWB base station. The pico base station pRRU performs energy-saving control.

It should be noted that since UWB base stations are usually only used for positioning, the transmitted data is mainly content related to positioning tag information, and the positioning cycle is in seconds, so the system traffic bandwidth requirement is small, usually no more than 1M. The RRU lower port can usually support different access devices, such as zigbee, Bluetooth, WLAN AP, UWB and other wireless devices. It supports usually 10M/100M/1000M adaptive electrical ports, and the resources of the entire link can also be reserved. Provides 1000M level forwarding. When the actual access device is a UWB base station, after being identified by the UWB management platform, the bandwidth requirements of each UWB base station preset by the user will be obtained.

It can be understood that the UWB management platform forwards the working status, bandwidth requirements and MAC addresses of each UWB base station in the current management area to the BBU, so that the BBU can perform energy-saving control on each UWB base station and the pRRU corresponding to each UWB base station. The specific control method is that the BBU comprehensively considers the working status of RRU and UWB, dynamically shuts down relevant network elements through POE, and uses the bandwidth requirements of each UWB base station to calculate the link bandwidth of each UWB base station, so that pRRU and EU can reserve resources.

The energy-saving method based on positioning equipment in this embodiment is applied to the UWB management platform, including: when obtaining the positioning tag information of multiple ultra-wideband UWB base stations, determining the current coverage area of each UWB base station; according to the positioning tag information of each UWB base station and the current coverage area to determine the working status of each UWB base station; send the working status, bandwidth requirements and MAC address of each UWB base station to the indoor baseband processing unit BBU, and use the BBU to determine the working status, bandwidth requirements and MAC address of each UWB base station. The UWB base station and the pRRU corresponding to each UWB base station perform energy saving control. Through the above method, the working status of each UWB base station is determined based on the positioning tag information and current coverage area of each UWB base station. The BBU performs energy saving based on the working status, bandwidth requirements and MAC address of each UWB base station and the pRRU corresponding to each UWB base station. Control, when 5G and UWB base stations work together, the actual forwarding resources are minimized while ensuring the normal operation of the network, ensuring maximum energy saving, while reducing the impact on the fronthaul network, and effectively improving energy Utilization.

Referring to Figure 4, Figure 4 is a schematic flow chart of a second embodiment of an energy saving method based on positioning equipment according to the present invention.

Based on the above-mentioned first embodiment, step S20 in the energy-saving method based on positioning equipment in this embodiment includes:

Step S21: Extract the positioning tag information in each UWB base station and determine the number of positioning tags in each UWB base station.

It should be noted that the UWB management platform extracts the positioning tag information in each UWB base station and determines the number of positioning tags in each UWB base station.

It is understandable that when there are too many UWB base stations for locating the same UWB positioning tag, the positioning accuracy will not improve linearly. At this time, the redundant UWB positioning base stations can be turned off. Usually for three-dimensional positioning, 4 UWB base stations are enough. Complete, in order to ensure positioning accuracy, a UWB base station with a larger distance and azimuth correlation should be selected for positioning to achieve energy saving. When there are no positioning tags in some areas for a long time, you only need to provide a UWB base station to detect whether there is a positioning tag. When a positioning tag exists, open the adjacent UWB base station and perform positioning operations, which is only used to detect whether the positioning tag exists. The existing UWB base stations should leave fewer UWB base stations while ensuring coverage. When it is determined that there will be no new positioning tags in the area, such as when all registered positioning tags are in the positioning process, the UWB base station can dynamically track the positioning tags. When the positioning tags are in a certain area, only adjacent ones can be The UWB base stations in the area are turned on, but the positioning base stations in non-adjacent areas are all turned off. When the user moves to a new area, it is re-judged which UWB base stations need to be turned off. to achieve maximum energy savings.

In a specific implementation, in order to ensure the accuracy of subsequent energy-saving management of UWB base stations, further, the positioning tag information in each UWB base station is extracted, and after the number of positioning tags of each UWB base station is determined, it also includes: When there is no UWB base station whose number of positioning tags is not the preset number in each UWB base station, the positioning dimension of the current management area is obtained; according to the positioning dimension, the current coverage area of each UWB base station, and the current management area in multiple UWB A plurality of third UWB base stations are determined in the base station; the working state of each third UWB base station is determined to be a power-on state.

It should be noted that the preset number is 0 in this embodiment. When there is no UWB base station with a positioning tag number other than the preset number in each UWB base station, it means that there is no positioning tag in each UWB base station. At this time, Only a small number of UWB base stations are reserved to ensure that it can monitor whether there are new positioning tags in the current management area.

It can be understood that positioning dimensions refer to the required dimensions when using UWB base stations for positioning, including but not limited to zero-dimensional positioning, one-dimensional positioning, two-dimensional positioning and three-dimensional positioning. According to the positioning dimensions, the current coverage area of each UWB base station and the current management area, determine the minimum number of UWB base stations that can monitor whether there are new positioning tags in the current management area among all UWB base stations managed by the UWB management platform, and can monitor The smallest number of UWB base stations with new positioning tags in the current management area is the third UWB base station, and the working state of the third UWB base station is determined to be the power-on state. Among all UWB base stations managed by the UWB management platform, the corresponding working status of the UWB base station except the third UWB base station is determined to be the power-off state. For example, as shown in Figure 5, for two-dimensional positioning, at least 3 UWB base stations are needed. In order to cover the equilateral triangle shaded area in Figure 5, it is ensured that each area is covered by at least 3 UWB base stations. One of the coverage methods is as follows. A total of 11 UWB base stations are required. In fact, when there are no UWB tags in the current management area, you only need to turn on four UWB base stations numbered 1, 5, 7, and 10 to monitor whether there are tags. exist. As shown in Figure 6, it is a UWB base station deployment diagram after energy saving in the right triangle shaded area.

Step S22: When there are multiple first UWB base stations whose number of positioning tags is not the preset number in each UWB base station, determine that the working state of each first UWB base station is a power-on state.

It should be noted that when there is a first UWB base station whose number of positioning tags is not the preset number in each UWB base station, it means that there is a positioning tag in the first UWB base station. At this time, all UWB positioning covering the area where the positioning tag is located needs to be enabled. The base station determines that the working state of the first UWB base station is the power-on state.

Step S23: Determine the second UWB base station adjacent to each first UWB base station among the multiple UWB base stations according to the current coverage area of each UWB base station.

It should be noted that in order to facilitate the rapid movement of the positioning tag, it is necessary to determine the UWB base station in the area adjacent to the current coverage area of the first UWB base station and the UWB base station in the area adjacent to the current coverage area of the first UWB base station.

Step S24: Determine that the working state of the second UWB base station is the power-on state.

It should be noted that when there is a first UWB base station whose number of positioning tags is not the preset number in each UWB base station, the working status of the first UWB base station and the second UWB base station is determined to be the power-on status, and the UWB management platform Among all managed UWB base stations, the corresponding working status of the UWB base station except the first UWB base station and the second UWB base station is determined to be the power-off state.

In this embodiment, the number of positioning tags of each UWB base station is determined by extracting the positioning tag information in each UWB base station; when there are multiple first UWB base stations in each UWB base station whose number of positioning tags is not the preset number, the number of positioning tags of each UWB base station is determined. The working state of a UWB base station is a power-on state; determine a second UWB base station adjacent to each first UWB base station among multiple UWB base stations according to the current coverage area of each UWB base station; determine the working state of the second UWB base station as Power-on status. Through the above method, the working status of each UWB base station is determined based on the number of positioning tags and the current coverage area of each UWB base station, providing an accurate basis for subsequent energy saving.

Referring to Figure 7, Figure 7 is a schematic flow chart of a third embodiment of an energy saving method based on positioning equipment according to the present invention.

In this embodiment, the energy-saving method based on positioning equipment is applied to BBU, including the following steps:

Step S01: Upon receiving the working status, bandwidth requirements and MAC address of each UWB base station sent by the UWB management platform, determine the information forwarding link of each UWB base station based on the MAC address of each UWB base station. The working status of each UWB base station It is determined by the UWB management platform based on the positioning tag information of each UWB base station and the current coverage area.

It should be noted that the execution subject of this embodiment is the BBU in the energy-saving system based on the positioning device. The energy-saving system based on positioning equipment includes UWB management platform and BBU. The energy-saving system based on positioning equipment formed in the 5G and UWB integration scenario is shown in Figure 2. In addition to BBU and UWB management platform, it also includes multiple UWB base stations and pRRUs. , expansion unit EU. Among them, the BBU, 5G core network, expansion unit EU, and pRRU are 5G network elements, and the UWB base station, UWB management platform, and positioning server are the network elements of the UWB high-precision positioning system. The UWB base station is hung on the pRRU through the Ethernet electrical port. The EU supplies power to the pRRU through the optical-electric hybrid cable. The pRRU supplies power to the UWB base station through the POE module. The UWB management platform is connected to the back side of the BBU through the backhaul network. At the same time, pRRU, EU, The BBU also forms a transmission network to provide data forwarding functions for UWB base stations and UWB management platforms.

It can be understood that the UWB management platform can determine which UWB base stations need to be turned on and which UWB base stations need to be turned off in the current management area based on the positioning tag information and current coverage area of each UWB base station. The working status of the UWB base station that needs to be turned on is that it is powered on. status, the working status of the UWB base station that needs to be turned off is the power-off status. At the same time, the UWB management platform determines the bandwidth requirements and MAC addresses of each UWB base station, and sends the bandwidth requirements, working status and MAC address of each UWB base station to the BBU.

In a specific implementation, in order to ensure that the BBU obtains an accurate information forwarding link based on the MAC address of each UWB base station, further, determining the information forwarding link of each UWB base station based on the MAC address of each UWB base station includes: The MAC address of the base station determines the pRRU code corresponding to each UWB base station; the pRRU and EU corresponding to each UWB base station are determined based on the pRRU code corresponding to each UWB base station; the information forwarding chain of each UWB base station is determined based on the pRRU and extension unit EU corresponding to each UWB base station. road.

It should be noted that the information forwarding link includes an RRU that forwards information and supplies power to each UWB base station, and an EU that supplies power to the pRRU corresponding to each UWB base station. The BBU queries the MAC address forwarding table of all pRRUs under the BBU based on the MAC address of each UWB base station, finds the pRRU code to which each UWB base station belongs, and determines the pRRU and EU corresponding to each UWB base station based on the pRRU code corresponding to each UWB base station. Based on each UWB The pRRU and EU corresponding to the base station constitute the information forwarding link of each UWB base station.

Step S02: Calculate the link bandwidth of each UWB base station according to the bandwidth requirement of each UWB base station.

It should be noted that when the BBU calculates the pRRU and EU corresponding to each UWB base station for information forwarding based on the bandwidth requirements of each UWB base station, the forwarding bandwidth requirements required by pRRU and EU are the forwarding bandwidth requirements required by pRRU and EU. The link bandwidth of the base station.

Step S03: Perform energy-saving control on each UWB base station and the pRRU corresponding to each UWB base station according to the link bandwidth, working status and information forwarding link of each UWB base station.

It should be noted that the BBU comprehensively considers the working status of pRRU and UWB, dynamically shuts down relevant network elements through POE, and uses the link bandwidth of each UWB base station to enable pRRU and EU to reserve resources.

The energy-saving method based on positioning equipment in this embodiment is applied to the BBU, including: when receiving the working status, bandwidth requirements and MAC address of each UWB base station sent by the UWB management platform, determining the UWB base station based on the MAC address of each UWB base station. Information forwarding link, the working status of each UWB base station is determined by the UWB management platform based on the positioning tag information and current coverage area of each UWB base station; the link bandwidth of each UWB base station is calculated according to the bandwidth requirements of each UWB base station; Energy-saving control is performed on each UWB base station and the pRRU corresponding to each UWB base station according to the link bandwidth, working status and information forwarding link of each UWB base station. Through the above method, energy-saving control is performed on each UWB base station and the pRRU corresponding to each UWB base station through the determined link bandwidth, working status and information forwarding link of each UWB base station. When 5G and UWB base stations work together, the normal network is ensured. When working, the actual forwarding resources are reduced to a minimum, ensuring maximum energy saving, while reducing the impact on the fronthaul network, and effectively improving energy utilization.

Referring to FIG. 8 , FIG. 8 is a schematic flow chart of a fourth embodiment of an energy saving method based on positioning equipment according to the present invention.

Based on the above third embodiment, step S03 in the energy saving method of positioning equipment in this embodiment includes:

Step S31: Determine the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station according to the information forwarding link of each UWB base station.

It should be noted that since the information forwarding link of each UWB base station includes the pRRU that forwards information and supplies power to each UWB base station, and the EU that supplies power to the pRRU corresponding to each UWB base station, therefore according to the information forwarding chain of each UWB base station The path can determine the pRRU and EU corresponding to each UWB base station.

Step S32: Send the link bandwidth of each UWB base station to the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station, and resource the link bandwidth of each UWB base station through the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station. Reserved.

It should be noted that the BBU sends the link bandwidth of each UWB base station to the pRRU corresponding to the UWB base station and the EU corresponding to each UWB base station. The EU and pRRU configure their own hardware or software resources to meet the forwarding requirements.

Step S33: When the working state of each UWB base station is the power-on state, send a resource reservation instruction to the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station, and send a base station power-on instruction to the pRRU corresponding to each UWB base station. The pRRU corresponding to each UWB base station powers on each UWB base station, and the link bandwidth is reserved through the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station.

It should be noted that pRRU, as a fronthaul radio unit, has a variety of energy-saving scenarios, including but not limited to: when multiple pRRUs are in overlapping coverage cells and each pRRU is independently responsible for a physical cell, if there are too many users in the current area or If the traffic is too large, turn on the RRU in the corresponding area for load sharing, as shown in Figure 9 where pRRU4 is located. When the number of users is small and the traffic demand is small, the processing of pRRU4 in the repeated coverage area is closed, which not only ensures the availability of the network for users, The purpose of energy saving is also achieved; when multiple RRUs are in the radio frequency merger state, as shown in Figure 10, multiple pRRUs belong to the same cell. When the user signal quality is poor, the spare pRRU4 can be opened to improve the signal strength. When the signal quality is good, pRRU4 can be turned off to save energy.

It can be understood that when it is determined that the working status of each UWB base station is the power-on state, resource reservation instructions are sent to the pRRU and EU corresponding to each UWB base station, so that the EU and pRRU reserve resources for the link bandwidth, and at the same time, send the resource reservation command on the base station. The power command is sent to the pRRU and EU corresponding to each UWB base station, so that the EU operates the POE power supply module to power on the pRRU corresponding to each UWB base station, and the pRRU operates the POE power supply module to power on each UWB base station.

Step S34: When the working state of each UWB base station is the power-off state, send a resource release command to the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station, send a base station power-off command to the pRRU corresponding to each UWB base station, and When the pRRU corresponding to each UWB base station is in the power-off state, send the pRRU power-off command to the EU corresponding to each UWB base station, power off each UWB base station through the pRRU corresponding to each UWB base station, and power off each UWB base station through the EU corresponding to each UWB base station. The pRRU corresponding to the UWB base station is powered off, and the link bandwidth resources are released through the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station.

It should be noted that when it is determined that the working status of each UWB base station is in the power-off state, resource release instructions are sent to the pRRU and EU corresponding to each UWB base station, so that the EU and pRRU release resources for the link bandwidth, and at the same time, send the base station to The power command is sent to the pRRU corresponding to each UWB base station, so that the pRRU operates the POE power supply module to power on each UWB base station. And determine whether the pRRU corresponding to the UWB base station in the power-off state is in the power-off state. When the pRRU corresponding to the UWB base station in the power-off state is in the power-off state, send a pRRU power-off command to the EU corresponding to each UWB base station to enable the EU to operate The POE power supply module powers off the pRRU corresponding to each UWB base station. In this embodiment, as shown in Figure 11, if the pRRU is in a power-off state and the UWB base station that the pRRU supplies power to is also in a power-off state, the pRRU can be powered off. In other cases, it is necessary to power off the pRRU. Power on the pRRU.

It can be understood that, as shown in Figure 12, the UWB management platform determines the working status of each UWB base station based on the number of positioning tags and the current coverage area of each UWB base station, determines the bandwidth requirements and MAC address of each UWB base station, and stores the above information Synchronize to the BBU side; the BBU needs to calculate the entire link bandwidth, and perform current limiting processing on the UWB base station at the RRU, control the network elements on the link to provide services, and complete the service with the minimum resources and minimum energy consumption. It is actually possible The operations include reducing the forwarding CPU frequency, allocating smaller CPU resources for forwarding processing, and allocating smaller hardware resources for EU, pRRU, etc. to ensure the forwarding rate and achieve energy saving. When UWB is turned off, the corresponding allocated forwarding resources also need to be released, and the corresponding ports can also be closed.

In this embodiment, the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station are determined based on the information forwarding link of each UWB base station; the link bandwidth of each UWB base station is sent to the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station. , reserve resources for the link bandwidth of each UWB base station through the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station; when the working status of each UWB base station is the power-on state, a resource reservation instruction is sent to the corresponding UWB base station The pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station are sent, and the base station power-on command is sent to the pRRU corresponding to each UWB base station. Each UWB base station is powered on through the pRRU corresponding to each UWB base station. Through the pRRU corresponding to each UWB base station and each UWB base station The corresponding EU reserves resources for the link bandwidth; when the working status of each UWB base station is in the power-off state, a resource release command is sent to the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station, and a base station power-off command is sent to each UWB base station. pRRU corresponding to the UWB base station, and when the pRRU corresponding to each UWB base station is in the power-off state, send the pRRU power-off command to the EU corresponding to each UWB base station, and power off each UWB base station through the pRRU corresponding to each UWB base station. The EU corresponding to each UWB base station powers off the pRRU corresponding to each UWB base station, and releases link bandwidth resources through the pRRU corresponding to each UWB base station and the EU corresponding to each UWB base station. Through the above method, resource management is carried out according to the information forwarding links of each UWB base station and the working status of each UWB base station, and each UWB base station is powered on and off to minimize the actual forwarding resources and ensure maximum energy saving and Reduce the impact on the fronthaul network.
