Currently, network-controlled relays can amplify and forward base station signals. However, if the signal is invalid, the network-controlled relays can easily perform invalid operations such as amplifying and forwarding the invalid signal. Therefore, the accuracy of current network-controlled relays in signal manipulation is poor. Summary of the Invention

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] The terms "first", "second" etc. in the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. In addition, the terms "comprise" and "have" and any deformation thereof are intended to cover non-exclusive inclusions, such as, the process, method, system, product or equipment comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or that are intrinsic to these processes, methods, products or equipment. In addition, "and / or" is used in the present application to represent at least one of connected objects, such as A and / or B and / or C, and represents comprising independent A, independent B, independent C, and A and B all exist, B and C all exist, A and C all exist, and 7 situations that A, B and C all exist.

[0031] Wireless repeaters are a low-cost solution for quickly improving the coverage performance of communication signals. Optionally, wireless repeaters can be 5th Generation Mobile Communication Technology (5G) wireless repeaters. The working principle of 5G wireless repeaters can be described as follows: the signals of surrounding 5G base stations are introduced into the target coverage area indoors through the return antenna of the repeater equipment, such as Figure 1 As shown, the 5G base station signal is then sent out through a small transceiver antenna; at the same time, the mobile terminal signal is received and transmitted back to the base station.

[0032] In an optional application scenario, wireless repeaters can be used in elevators in residential areas to improve the communication performance of residential areas. The wireless repeaters in this scenario can be called elevator-type wireless repeaters, and the elevator-type wireless repeater is a two-stage cascade repeater architecture, including a repeater host and slaves. The host is installed in the machine room at the top of the elevator shaft, and its return antenna is installed outdoors to receive outdoor 5G wireless signals. The retransmission antenna is installed at the top of the elevator shaft. The slave is installed in the elevator car, and its return antenna is installed at the top of the car outside the elevator car to receive the host retransmission antenna signal. The retransmission antenna is installed at the top of the car inside the elevator car to transmit the signal forwarded and amplified by the repeater and access user terminals with business needs. The antennas used in the elevator-type wireless repeater include the main control unit receiving antenna, the coverage antenna, the car unit receiving antenna, and the coverage antenna. The working diagram is as follows: Figure 2 shown.

[0033] Currently, elevator-type wireless repeaters are typically installed in the elevator machine room of high-rise residential buildings to address the problem of poor signal quality in the elevator lobby. The repeater's main equipment is mounted on the roof, and the return antenna is placed on the vertical surface of the rooftop's exterior wall. In taller residential buildings, such as those above the 35th floor, the return antenna's height is approximately 100-110 meters, significantly higher than surrounding base station antennas. If the return antenna is improperly positioned, the wireless repeater, facing multiple, uncontrolled New Radio (NR) Node Bs (gNBs), will directly transmit the signal from the source base station, raising the noise floor. This will not only result in user terminals experiencing full signal but unable to connect or experiencing slow access, but will also cause interference to surrounding gNB base stations. Traditional wireless repeater installation involves construction teams relying on their engineering experience to select locations near windows and at entrances to receive signals from surrounding 5G base stations as the source signal. However, during the installation of the repeater, it may be impossible to accurately select a reasonable source signal. When the 5G base station signal input by the backhaul antenna is weak and there is no master control source signal, the wireless repeater cannot effectively amplify the source signal.

[0034] It should be noted that the above-mentioned wireless repeater can also be understood as a network-controlled relay. The Network Controlled Repeater (NCR) defined in the 3rd Generation Partnership Project (3GPP) Release 18 (R18) introduces a control module based on the forwarding module, enabling the network-controlled relay to perform timed and directional forwarding under the control of the base station, thereby reducing network interference.

[0035] 3GPP Standardization Group (TSG) 38.300 i10 defines: NCR consists of two parts: the mobile terminal of the network control relay (NCR Mobile Terminal, NCR-MT) and the forwarding terminal of the network control relay (NCR Forwarding, NCR-Fwd), such as Figure 3 As shown in the figure, the NCR-MT is a control module, an entity that supports a subset of user equipment (UE) functions. It communicates with the NR Node B (gNB) via a control link based on the New Radio (NR) Uu interface to receive control information from the gNB. The NCR-Fwd is a forwarding module that amplifies and forwards signals between the gNB and the UE via the NCR-Fwd backhaul link and the NCR-Fwd access link, respectively. The NCR-Fwd can support multi-beam pointing towards the terminal.

[0036] The NCR-MT establishes a Signaling Radio Bearer (SRB) and an optional Data Radio Bearer (DRB) with the gNB. The DRB can be used to transmit Operations, Administration, and Maintenance (OAM) services. The signals forwarded by the NCR-Fwd are associated with the gNB to which the NCR-MT is connected via a control link. Whether the NCR-Fwd can forward other signals depends on the specific configuration of the NCR-MT.

[0037] NR Radio Resource Control (RRC) signaling configures the NCR-MT to receive control information from the gNB. The NCR-Fwd uses this control information to determine whether and how to amplify and forward signals. If the gNB-side control configuration is canceled, the NCR-Fwd's amplification and forwarding functionality ceases.

[0038] The NCR-MT performs the same cell search, system information acquisition, random access, uplink control information (UCI) reporting, or physical downlink control channel (PDCCH) detection procedures as the UE. The NCR-MT performs the same procedures for physical downlink shared channel (PDSCH) reception, channel state information reference signal (CSI-RS) and channel state information (CSI) measurements, and physical uplink shared channel (PUSCH) transmission or sounding reference signal (SRS) transmission as the UE.

[0039] Based on the technical principles of NCR, the above problem still cannot be effectively resolved. If the NCR-MT receives wireless signals from multiple gNBs without a master, it cannot stably reside on a single gNB cell and cannot establish an effective control link. According to the NCR operating principle, the signals forwarded by the NCR-Fwd are associated with the gNB to which the NCR-MT is connected via the control link. Whether the NCR-Fwd can forward other signals depends on the specific configuration of the NCR-MT. However, if the NCR-MT cannot stably reside on a single gNB, it cannot establish an effective control link and cannot control the NCR-Fwd for forwarding and amplification.

[0040] In order to solve the above technical problems, the following embodiments of the present application are proposed, and the inventive idea of ​​the embodiments of the present application can be: for the problem that the deployment position of the backhaul antenna of the elevator-type repeater is much higher than the height of the base station antenna, the repeater receives multiple gNB wireless signals without a master control, and directly transmits the wireless signal of the source base station, resulting in an increase in the background noise interference, a control instruction sending method is proposed, which uses a network management monitoring platform to coarsely screen the 5G base station positions around the network control relay, sends a first control instruction to the NCR-MT module, measures the reference signal receiving power (RSRP) of the surrounding 5G source base stations; triggers a lightweight service to measure the service quality signal and interference plus noise ratio (Signal to Interference plus Noise Ratio) after residing at the source base station; Ratio, SINR), after the network management monitoring platform receives the target information measured by NCR-MT, which includes RSRP and SINR, it determines the current backhaul antenna deployment position based on the target information. If the preset conditions are not met, a control message is sent to the NCR-MT module to disable signal amplification and forwarding. In this way, by controlling the NCR-MT module to perform RSRP signal measurement and service quality testing, and feedback on SINR quality, the network can control the relay's residence and access to the source base station.

[0041] For details, please refer to Figure 4 , Figure 4 It is a flowchart of the control instruction sending method provided in an embodiment of the present application. Figure 4 The control instruction sending method shown can be executed by an electronic device, and the electronic device can also be called a network management monitoring platform.

[0042] like Figure 4 As shown, the control instruction sending method may include the following steps:

[0043] Step 401: Send a first control instruction to the NCR-MT of the network control relay, where the first control instruction is used to enable the NCR-MT to measure and obtain target information of a source base station within a preset range of the NCR-MT.

[0044] Among them, the preset range of NCR-MT can be understood as a range centered on NCR-MT and with a distance from NCR-MT less than or equal to the preset distance. When the source base station is within the above preset range, the source base station can be understood as a peripheral base station of NCR-MT.

[0045] The target information may include at least one of quality information and strength information of the source base station, which is not specifically limited here.

[0046] Optionally, the NCR-MT may include a master NCR-MT and a slave NCR-MT, and the network management monitoring platform may send a first control instruction to at least one of the master NCR-MT and the slave NCR-MT, so that at least one of the master NCR-MT and the slave NCR-MT measures the target information of the source base station within a preset range of the NCR-MT.

[0047] For example, the network management monitoring platform may send a first control instruction to the host NCR-MT and the slave NCR-MT respectively, so that the host NCR-MT and the slave NCR-MT respectively measure the target information of the source base station within the preset range of the NCR-MT, thereby improving the accuracy of the measurement results of the target information.

[0048] It should be noted that, optionally, the network management and monitoring platform can be based on the NCR working principle to screen and obtain the source base stations within the preset range of NCR-MT, and the network management and monitoring platform can be understood as a network management platform independent of the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) network, and the source base stations can be base stations in the 5G network, see Figure 5 The network management and monitoring platform can connect to the Radio Access Network (RAN), Access and Mobility Management Function (AMF) network, and User Plane Function (UPF) network in the 5G network, and can be used to monitor the signaling and data flows of the N1, N2, and N3 interfaces. In addition, see Figure 5 , 5G network can also include data network (Data Network, DN).

[0049] Step 402: Receive the target information sent by the NCR-MT, and determine whether the target information meets a preset condition to obtain a determination result, where the preset condition is used to indicate that the signal quality of the source base station meets a communication requirement.

[0050] The judgment result may be that the target information meets the preset condition, or the judgment result may be that the target information does not meet the preset condition.

[0051] Step 403: Send a second control instruction corresponding to the judgment result to the NCR-MT, where the second control instruction is used to cause the NCR-MT to perform a target operation. Wherein, if the judgment result is that the target information does not meet the preset condition, the target operation includes not sending a third control instruction to the NCR-Fwd of the network control relay, where the third control instruction is used to cause the NCR-Fwd to perform an amplification operation and a forwarding operation.

[0052] Among them, the judgment result and the target operation can correspond one to one, for example: when the judgment result is that the target information does not meet the preset conditions, the target operation is not to send the third control instruction to the forwarding end NCR-Fwd of the network control relay; when the judgment result is that the target information meets the preset conditions, the target operation is to send the third control instruction to the forwarding end NCR-Fwd of the network control relay.

[0053] In the embodiment of the present application, through steps 401 to 403, when the judgment result is that the target information does not meet the preset conditions, the third control instruction is not sent to the forwarding end NCR-Fwd of the network control relay. The third control instruction is used to enable NCR-Fwd to perform amplification and forwarding operations. In this way, the network control relay does not need to perform invalid operations such as amplification and forwarding on invalid signals, thereby improving the accuracy of the network control relay's operation on the signal.

[0054] That is, the network management monitoring platform can determine whether the target information meets the preset conditions and control whether the NCR-Fwd performs amplification and forwarding operations, thereby avoiding the amplification and forwarding of invalid signals, and avoiding the unreasonable setting position of the host retransmission antenna of the network control relay, which leads to the source base station being messy and without a master control, and the NCR-Fwd cannot effectively amplify the source signal normally and cause interference to the surrounding network.

[0055] As an optional implementation, when the judgment result is that the target information does not meet the preset condition, the target operation also includes sending a prompt message to the electronic device, and the prompt message is used to prompt the host retransmission antenna of the network control relay to redeploy.

[0056] The electronic equipment may refer to electronic equipment used by staff, or the electronic equipment may refer to electronic equipment in a duty room, or the electronic equipment may refer to electronic equipment in a monitoring room.

[0057] It should be noted that the specific method of sending the prompt information to the electronic device is not limited here. Optionally, the method of sending the prompt information to the electronic device may include at least one of the following: telephone notification, SMS notification, email notification, etc.

[0058] The form of the prompt information may include at least one of the following: voice prompt information, image prompt information, text prompt information, etc.

[0059] In an embodiment of the present application, when the judgment result is that the target information does not meet the preset conditions, the target operation also includes sending a prompt message to the electronic device, and the prompt message is used to prompt the host retransmission antenna of the network control relay to be redeployed. In this way, by redeploying the host retransmission antenna of the network control relay until the target information meets the preset conditions, the detection effect of the network control relay on the signal of the source base station is improved.

[0060] It should be noted that, in the related art, the setting position of the host retransmission antenna of the network control relay is usually determined by relying on the work experience of the staff, while in the implementation manner of the present application, by determining whether the target information meets the preset conditions, and when the target information does not meet the preset conditions, the position of the host retransmission antenna can be adjusted, and after adjusting the position of the host retransmission antenna, the target information is detected again, and it is determined whether the target information meets the preset conditions. By combining the changes in the target information before and after adjusting the position of the host retransmission antenna, the position of the host retransmission antenna can be gradually adjusted. In this way, by adjusting the position of the host retransmission antenna multiple times in a cycle, and based on the changes in the target information before and after adjusting the position of the host retransmission antenna, the optimal setting position of the host retransmission antenna can be determined.

[0061] It should be noted that the host retransmission antenna can be called a part of a wireless repeater or an NCR repeater.

[0062] As an optional implementation, when the judgment result is that the target information meets the preset condition, the target operation includes sending a third control instruction to the NCR-Fwd, where the third control instruction is used to enable the NCR-Fwd to perform an amplification operation and a forwarding operation.

[0063] Among them, optionally, NCR-Fwd performs amplification operations and forwarding operations mainly referring to: NCR-Fwd can perform amplification operations and forwarding operations on the signal forwarded and amplified by the host retransmission antenna of the network control relay, so that the signal forwarded and amplified by the host retransmission antenna can be secondary amplified and forwarded.

[0064] In an embodiment of the present application, when the target information meets the preset conditions, it means that the signal of the source base station measured by the NCR-MT meets the communication requirements. At this time, a third control instruction can be sent to the NCR-Fwd. The third control instruction is used to enable the NCR-Fwd to perform amplification operations and forwarding operations, so that the amplification operations and forwarding operations performed by the NCR-Fwd are not invalid operations, thereby improving the accuracy of the amplification operations and forwarding operations performed by the NCR-Fwd.

[0065] As an optional implementation manner, the NCR-MT includes a master NCR-MT and a slave NCR-MT, the target information includes a first RSRP signal strength, a first signal quality value, a second RSRP signal strength, and a second signal quality value of the source base station, where the first RSRP signal strength and the first signal quality value are both information measured by the master NCR-MT, and the second RSRP signal strength and the second signal quality value are both information measured by the slave NCR-MT;

[0066] The preset conditions include:

[0067] The first RSRP signal strength is greater than a first preset threshold;

[0068] The first signal quality value is greater than a second preset threshold;

[0069] The second RSRP signal strength is greater than a third preset threshold;

[0070] The second signal quality value is greater than a second preset threshold.

[0071] Among them, the first preset threshold can be referred to as threshold T1, and the specific value of T1 is not limited here, optionally, T1=-105dBm, the second preset threshold can be referred to as threshold T2, and the specific value of T2 is not limited here, optionally, T2=0dB; the third preset threshold can be referred to as threshold T3, and the specific value of T3 is not limited here, optionally, T3=-105dBm; the fourth preset threshold can be referred to as threshold T4, and the specific value of T4 is not limited here, optionally, T4=1dB.

[0072] The first signal quality and the second signal quality may both be referred to as signal to interference plus noise ratio (SINR) signal quality of the source base station.

[0073] In an embodiment of the present application, the target information includes the first RSRP signal strength, the first signal quality value, the second RSRP signal strength and the second signal quality value of the source base station. In this way, the diversity of the types of target information is increased, and the more types of target information there are, the higher the accuracy of the result of judging whether the target information meets the preset conditions.

[0074] As an optional implementation manner, the master NCR-MT and the slave NCR-MT are cascaded, and the corresponding relationship between the master NCR-MT and the slave NCR-MT is stored in a preset relationship table.

[0075] Among them, the network management monitoring platform can identify the host NCR-MT and the slave NCR-MT. The slave NCR-MT needs to receive the signal forwarded and amplified by the host retransmission antenna for secondary amplification. The host NCR-MT and the slave NCR-MT establish a corresponding relationship table. After the network management monitoring platform receives the measurement signals fed back by the host NCR-MT and the slave NCR-MT, it establishes the corresponding relationship between the host NCR-MT and the slave NCR-MT according to the corresponding relationship table, and stores the corresponding relationship between the host NCR-MT and the slave NCR-MT in the preset relationship table.

[0076] In the embodiment of the present application, the correspondence between the master NCR-MT and the slave NCR-MT is stored in a preset relationship table. In this way, the cascade relationship between the master NCR-MT and the slave NCR-MT can be accurately determined through the preset relationship table.

[0077] As an optional implementation manner, before sending the first control instruction to the mobile terminal NCR-MT of the network control relay, the method further includes:

[0078] Determining the location information of the network control relay based on the acquired base station location information and electronic map information in the wireless access network;

[0079] The signal source base station is determined according to the location information of the network control relay.

[0080] Among them, the base station location information can be understood as the latitude and longitude information of the base station, and the above-mentioned base station location information can be stored in the wireless access network RAN; the electronic map information can refer to the information stored in the server corresponding to the electronic map application, and the server corresponding to the electronic map application can pre-store the electronic map information of various places, the location information corresponding to the base station in the electronic map information, and the location information corresponding to the network control relay in the electronic map information.

[0081] In the implementation manner of the present application, the information source base station is determined based on the location information of the network control relay, so that the accuracy of the location of the information source base station can be improved.

[0082] As an optional implementation manner, determining the signal source base station according to the location information of the network controlled relay includes:

[0083] Determine a first candidate base station set according to the location information of the network control relay, where the first candidate base station set includes multiple base stations;

[0084] Sending a fourth control instruction to the NCR-MT, and receiving information of a second candidate base station set replied by the NCR-MT to the fourth control instruction, where the second candidate base station set includes multiple base stations;

[0085] When the overlap between the base stations included in the first candidate base station set and the base stations included in the second candidate base station set is greater than a preset overlap, multiple base stations included in the first candidate base station set or base stations included in the second candidate base station set are determined as the signal source base stations.

[0086] Among them, the network management monitoring platform can preliminarily determine the location information of the network control relay based on the latitude and longitude information of the base station and the electronic map information, and then calculate the distance between the network control relay and the 5G signal source base stations around the network control relay. Figure 6 According to the projection theorem, the effective coverage range of each sector of the surrounding source base stations of the network control relay is calculated, so that the 5G source base stations around the network control relay can be preliminarily judged, and these source base stations can be listed as the source base stations in the set H1, and the set H1 can be used to represent the first candidate base station set.

[0087] Among them, the network management monitoring platform can send a fourth control instruction to NCR-MT, and NCR-MT can measure the target information of the source base station within the preset range of the network control relay according to the fourth control instruction. The network management monitoring platform can receive the target information of the second candidate base station set replied by NCR-MT to the fourth control instruction, and the above-mentioned second candidate base station set can be referred to as set H2.

[0088] It should be noted that the specific content of the above-mentioned target information in the implementation manner of the present application is not limited here. Optionally, the above-mentioned target information may be RSRP signal strength.

[0089] The preset overlap degree may be referred to as a threshold value T0, and the specific value of the threshold value T0 is not limited here. Optionally, the threshold value T0 may be 80%.

[0090] In an embodiment of the present application, when the degree of overlap between the base stations included in the first candidate base station set and the base stations included in the second candidate base station set is greater than the preset degree of overlap, it indicates that at this time, most of the base stations included in the first candidate base station set and the base stations included in the second candidate base station set are base stations within the preset range of NCR-MT. Therefore, multiple base stations included in the first candidate base station set or base stations included in the second candidate base station set can be determined as signal source base stations, thereby improving the accuracy of the determination result of the signal source base station.

[0091] It should be noted that when the degree of overlap between the base stations included in the first candidate base station set and the base stations included in the second candidate base station set is less than or equal to the preset overlap, it means that the source base stations measured by the NCR-MT at this time include base stations outside the preset range, thereby interfering with the determination result of the source base station. At this time, the source base stations within the preset range of the NCR-MT can be re-divided and determined, or the preset range can be re-determined.

[0092] As an optional implementation manner, the sending of the first control instruction to the mobile terminal NCR-MT of the network control relay includes:

[0093] Obtaining access and authentication result information of the network control relay;

[0094] When the result information indicates that the access and authentication of the network control relay are passed, the first control instruction is sent to the NCR-MT.

[0095] The specific process of network control relay access and authentication can be seen as follows:

[0096] Among them, see Figure 7 , NCR-MT can monitor broadcast messages and system messages through SIB1 messages to obtain information about whether the gNB supports NCR (NCR-support indication in SIB1). During the access process, NCR indicates NCR information to the source base station (ncr-NodeIndication-r18). After the NCR accesses the gNB, it obtains the access AMF message. The AMF provides the gNB with NCR authentication information. For the specific access and authentication process, please refer to Figure 7 Follow steps 1 to 9 in the .

[0097] In the implementation manner of the present application, the first control instruction is sent to the NCR-MT only when the result information indicates that the access and authentication of the network control relay are passed, thereby improving the accuracy of sending the first control instruction and avoiding the phenomenon of invalidly sending the first control instruction to the NCR-MT when the access and authentication of the network control relay are not passed.

[0098] As an optional implementation manner, after sending the second control instruction corresponding to the judgment result to the NCR-MT, the method further includes:

[0099] Obtaining an interference signal from the source base station;

[0100] In a case where the value of the interference signal is greater than the target threshold, a fifth control instruction is sent to the NCR-MT, where the fifth control instruction is used to cause the NCR-Fwd to stop performing the amplification operation and the forwarding operation.

[0101] The target threshold may be referred to as threshold T5. Optionally, threshold T5 may be equal to -105 dBm.

[0102] The interference signal may include at least one of a cell interference signal, a cell interference average value signal, and an average value of received interference of each PRB.

[0103] The cell interference signal may refer to N.UL.NI.Avg, and N.UL.NI.Avg may refer to the average value of upper and lower interference noise;

[0104] The cell interference average signal can refer to N.UL.NI.Avg.PRB0~PRBxxx, that is, the average value of the upper and lower interference noise between PRBs 0 and XXX. The value of XXX varies in different cells. For example, in an NR time division duplexing (TDD) 100MHz cell, the PRB range is: PRB0-PRB272, that is, XXX is 272;

[0105] The average receive interference value for each PRB can be obtained by collecting the following performance statistics at the hourly granularity:

[0106] Uplink interference noise received per PRB (cell level): This value calculates the average value N.UL.NI.Avg of the uplink and downlink interference noise detected per PRB.

[0107] In the embodiment of the present application, when the value of the interference signal is greater than the target threshold, it means that the influence of the interference signal is greater at this time, and therefore a fifth control instruction can be sent to the NCR-MT. The fifth control instruction is used to stop the NCR-Fwd from performing amplification operations and forwarding operations, thereby reducing the occurrence of errors in the NCR-Fwd performing amplification operations and forwarding operations under the interference of the interference signal, and improving the accuracy of the NCR-Fwd performing amplification operations and forwarding operations.
