Detailed implementation manners

[0012] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0013] The terms "first", "second", etc. in the embodiments of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. In addition, the terms "include" and "have" and any of their deformations are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily need to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices. In addition, the use of "and / or" in the present application represents at least one of the connected objects. For example, A and / or B and / or C represents 7 cases including A alone, B alone, C alone, A and B existing, B and C existing, A and C existing, and A, B, and C existing.

[0014] A wireless repeater is a low-cost solution for quickly improving the coverage performance of communication signals. Optionally, the wireless repeater can be a 5th Generation Mobile Communication Technology (5G) wireless repeater, and the working principle of the 5G wireless repeater can be referred to the following description: The signals of surrounding 5G base stations are introduced into the target coverage area indoors through the return antenna of the repeater device, such as Figure 1 shown, and then the 5G base station signals are transmitted through a small transceiver antenna; at the same time, the mobile phone terminal signals are received and returned to the base station.

[0015] In an alternative application scenario, the wireless repeater can be applied in the elevator of a residential community to improve the communication performance of the residential community. The wireless repeater in this scenario can be called an elevator-type wireless repeater, and the elevator-type wireless repeater is a two-stage cascaded repeater architecture, including a main unit and a slave unit. The main unit is installed in the machine room at the top of the elevator shaft, its return antenna is installed outdoors, receiving outdoor 5G wireless signals, and the retransmission antenna is installed at the top of the elevator shaft; the slave unit is installed in the elevator car, its return antenna is installed at the upper end of the car outside the elevator car, used to receive the signal of the main unit's retransmission antenna, and its retransmission antenna is installed at the top of the car inside the elevator car, used to transmit the signal amplified by the repeater and access user terminals with service requirements. The antennas used in the elevator-type wireless repeater include a main control unit receiving antenna, a coverage antenna, a car unit receiving antenna, and a coverage antenna. The working schematic diagram is as Figure 2 shown.

[0016] Currently, elevator-type wireless repeaters are generally installed in the elevator machine rooms of high-rise residential buildings to solve the problem of poor signal in the elevator shaft. The main repeater device is installed on the roof, and the return antenna is placed on the vertical surface of the outdoor wall of the roof. In the scenario where the residential building is too high, such as above 35 floors, the height of the return antenna is about 100-110 meters, which is much higher than the surrounding base station antennas. If the placement position of the return antenna is unreasonable, the wireless repeater faces multiple and non-mastered New Radio (NR) nodes (NR Node B, gNB) wireless signals, and directly transmits the wireless signals of the source base station, resulting in an increase in the background noise interference. This will not only cause the user terminal to display a full signal but cannot access or access slowly, but also interfere with the surrounding gNB base stations. The traditional installation process of the wireless repeater is that the construction team relies on engineering experience to select window sides and household entry positions to place the return antenna of the repeater, so as to receive the 5G base station signals of the surrounding area as the source signals. However, during the installation process of the repeater, it may not be possible to accurately select a reasonable source signal. When the 5G base station signal input by the return antenna is weak and there is no mastered source signal, the wireless repeater cannot effectively amplify the source signal normally.

[0017] It should be noted that the above wireless repeater can also be understood as a network-controlled repeater. The network-controlled repeater (NCR) defined in the 3rd Generation Partnership Project (3GPP) Release 18 (R18) introduces a control module on the basis of the forwarding module, enabling the network-controlled repeater to perform timed and directional forwarding under the control of the base station, which can reduce network interference.

[0018] Defined in 3GPP Technical Specification Group (TSG) 38.300 i10: NCR consists of two parts, namely the mobile terminal of the network-controlled repeater (NCR Mobile Terminal, NCR-MT) and the forwarding end of the network-controlled repeater (NCR Forwarding, NCR-Fwd), as Figure 3 shown. NCR-MT is the control module, which is an entity that supports a subset of the functions of the user equipment (UE). It communicates with the NR node (NR Node B, gNB) through a control link based on the New Radio (NR) Uu interface to receive control information from the gNB side. NCR-Fwd is the forwarding module, which has the function of amplifying and forwarding signals between the gNB and the UE through the NCR-Fwd backhaul link and the NCR-Fwd access link respectively. NCR-Fwd can support multi-beam pointing to the terminal.

[0019] NCR-MT establishes a signalling radio bearer (SRB) and an optional data radio bearer (DRB) with the gNB. The establishment of the DRB can be used to transmit operations, administration, and maintenance (OAM) services. The signal forwarded by NCR-Fwd is associated with the gNB connected by NCR-MT through the control link. Whether NCR-Fwd can forward other signals depends on the specific configuration of NCR-MT.

[0020] The NR radio resource control (RRC) signalling is used to configure NCR-MT to receive control information from the gNB side. NCR-Fwd uses this control information to determine whether and how to amplify and forward the signal. If the control configuration on the gNB side is cancelled, the amplification and forwarding function of NCR-Fwd will stop.

[0021] The procedures by which the NCR-MT performs cell search, system information acquisition, random access procedure, uplink control information (UCI) reporting, or physical downlink control channel (PDCCH) detection are the same as the corresponding procedures of the UE. The procedures by which the NCR-MT performs physical downlink shared channel (PDSCH) reception, channel state information reference signal (CSI-RS) measurement, channel state information (CSI) measurement, physical uplink shared channel (PUSCH) transmission, or sounding reference signal (SRS) transmission are the same as the corresponding procedures of the UE.

[0022] Based on the technical principle of NCR, the above problems still cannot be reasonably solved. If the NCR-MT receives multiple gNB radio signals without a master, the NCR-MT cannot stably camp on a certain gNB cell, and an effective control link cannot be established. According to the working principle of NCR, the signal forwarded by NCR-Fwd is associated with the gNB connected by the NCR-MT through the control link. Whether NCR-Fwd can forward other signals depends on the specific configuration of the NCR-MT. However, if the NCR-MT cannot stably camp on a certain gNB base station, an effective control link cannot be established, and NCR-Fwd cannot be controlled to perform forwarding and amplification.

[0023] To solve the above technical problems, the following embodiments of the present application are proposed. The inventive concept of the embodiments of the present application can be: aiming at 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 signals of the source base station transparently, resulting in an increase in the bottom noise interference. A control instruction sending method is proposed. The network management monitoring platform is used to roughly screen the positions of 5G base stations around the network control relay, and send a first control instruction to the NCR-MT module to measure the reference signal receiving power (RSRP) of the surrounding 5G source base stations; after camping on the source base station, trigger the measurement of the service quality signal and the signal to interference plus noise ratio (SINR). After the network management monitoring platform receives the target information measured and fed back by the NCR-MT, the target information includes RSRP and SINR. According to the target information, a decision is made on the current backhaul antenna deployment position. If the preset conditions are not met, a control message for not starting signal amplification and forwarding is sent to the NCR-MT module. In this way, by controlling the NCR-MT module to perform RSRP signal measurement and service quality testing, and feedback the SINR quality, the effect of controlling the network control relay to camp on and access the source base station is achieved.

[0024] Specifically, refer to Figure 4 , Figure 4 which is a schematic flowchart of the control instruction sending method provided by the embodiments of the present application. Figure 4 The control instruction sending method shown can be executed by an electronic device, and this electronic device can also be referred to as a network management monitoring platform.

[0025] As Figure 4 shown, the control instruction sending method may include the following steps: Step 401: Send a first control instruction to the NCR-MT of the network control relay. The first control instruction is used to enable the NCR-MT to measure the target information of the source base station within the preset range of the NCR-MT.

[0026] Among them, the preset range of the NCR-MT can be understood as a range centered on the NCR-MT and with a distance from the NCR-MT less than or equal to a preset distance. When the source base station is within the above preset range, the source base station can be understood as the surrounding base station of the NCR-MT.

[0027] Among them, the target information may include at least one of the quality information and the intensity information of the source base station, and specific details are not limited here.

[0028] Optionally, the NCR-MT may include a master NCR-MT and a slave NCR-MT, and the network management and 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 the preset range of the NCR-MT.

[0029] For example: the network management and monitoring platform may send a first control instruction to the master NCR-MT and the slave NCR-MT respectively, so that the master 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 result of the target information.

[0030] It should be noted that, optionally, the network management and monitoring platform may screen out the source base stations within the preset range of the NCR-MT based on the NCR working principle, and the network management and monitoring platform may be understood as a network management platform independent of the 5th Generation Mobile Communication Technology (5G) network, and the source base station may be a base station in the 5G network. See Figure 5 , the network management and monitoring platform may be connected to the Radio Access Network (RAN), Access and Mobility management Function (AMF) network, and User Plane Function (UPF) network in the 5G network, and the network management and monitoring platform may be used to monitor the N1, N2, and N3 interface signaling and data streams. In addition, see Figure 5 , the 5G network may further include a Data Network (DN).

[0031] 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 the communication requirements.

[0032] Among them, the determination result may be that the target information meets the preset condition, or the determination result may be that the target information does not meet the preset condition.

[0033] Step 403: Send a second control instruction corresponding to the judgment result to the NCR-MT. The second control instruction is used to cause the NCR-MT to perform a target operation. Wherein, when 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. The third control instruction is used to cause the NCR-Fwd to perform an amplification operation and a forwarding operation.

[0034] Wherein, the judgment result and the target operation can be in one-to-one correspondence. For example, when the judgment result is that the target information does not meet the preset condition, the target operation is not to send a 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 condition, the target operation is to send a third control instruction to the forwarding end NCR-Fwd of the network control relay.

[0035] 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 condition, a third control instruction is not sent to the forwarding end NCR-Fwd of the network control relay. The third control instruction is used to cause the NCR-Fwd to perform an amplification operation and a forwarding operation. In this way, it can be ensured that the network control relay does not perform invalid operations such as amplification and forwarding on invalid signals, and improves the accuracy of the network control relay's operation on signals.

[0036] That is, it is possible to control whether the NCR-Fwd performs an amplification operation and a forwarding operation according to the judgment result of whether the target information meets the preset condition by the network management monitoring platform, so as to avoid the amplification and forwarding of invalid signals, and avoid the situation where the setting position of the host retransmission antenna of the network control relay is unreasonable, resulting in chaotic and uncontrolled source base stations, and the NCR-Fwd cannot effectively amplify the source signal and cause interference to the surrounding network.

[0037] As an optional implementation manner, when the judgment result is that the target information does not meet the preset condition, the target operation further includes sending a prompt message to an electronic device. The prompt message is used to prompt to redeploy the host retransmission antenna of the network control relay.

[0038] Wherein, the electronic device may refer to an electronic device used by a staff member, or the electronic device may also refer to an electronic device in a duty room, or the electronic device may also refer to an electronic device in a monitoring room.

[0039] It should be noted that the specific manner of sending the prompt message to the electronic device is not limited herein. Optionally, the manner of sending the prompt message to the electronic device may include at least one of the following: phone notification, text message notification, email notification, etc.

[0040] Among them, the form of the prompt information may include at least one of the following: voice prompt information, image prompt information, text prompt information, etc.

[0041] In the embodiment of the present application, when the judgment result is that the target information does not meet the preset condition, the target operation further includes sending a prompt information to the electronic device, and the prompt information 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 condition, the detection effect of the network control relay on the signal of the source base station is improved.

[0042] 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 relying on the work experience of the staff. In the embodiment of the present application, by determining whether the target information meets the preset condition, and when the target information does not meet the preset condition, 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 judged whether the target information meets the preset condition. By combining the changes of 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 loop, and according to the changes of 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.

[0043] It should be noted that the above host retransmission antenna can be regarded as a part of a wireless repeater or an NCR repeater.

[0044] As an optional implementation manner, 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, and the third control instruction is used to make the NCR-Fwd perform an amplification operation and a forwarding operation.

[0045] Among them, optionally, the NCR-Fwd performing the amplification operation and the forwarding operation mainly means that the NCR-Fwd can perform an amplification operation and a forwarding operation on the amplified signal relayed by the host retransmission antenna of the network control relay, so as to perform secondary amplification and forwarding on the amplified signal relayed by the host retransmission antenna.

[0046] In the embodiment of the present application, when the target information meets the preset condition, 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, and the third control instruction is used to make the NCR-Fwd perform an amplification operation and a forwarding operation, so that the amplification operation and the forwarding operation performed by the NCR-Fwd are not invalid operations, and the accuracy of the NCR-Fwd performing the amplification operation and the forwarding operation is improved.

[0047] As an alternative implementation, the NCR-MT includes a master NCR-MT and a slave NCR-MT. 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. Both the first RSRP signal strength and the first signal quality value are information measured by the master NCR-MT, and both the second RSRP signal strength and the second signal quality value are information measured by the slave NCR-MT; The preset conditions include: The first RSRP signal strength is greater than a first preset threshold; The first signal quality value is greater than a second preset threshold; The second RSRP signal strength is greater than a third preset threshold; The second signal quality value is greater than a second preset threshold.

[0048] 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 = -105 dBm. The second preset threshold can be referred to as threshold T2, and the specific value of T2 is not limited here. Optionally, T2 = 0 dB. The third preset threshold can be referred to as threshold T3, and the specific value of T3 is not limited here. Optionally, T3 = -105 dBm. The fourth preset threshold can be referred to as threshold T4, and the specific value of T4 is not limited here. Optionally, T4 = 1 dB.

[0049] Among them, both the first signal quality and the second signal quality can be referred to as the signal to interference plus noise ratio (SINR) signal quality of the source base station.

[0050] In the implementation manner 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 determining whether the target information meets the preset conditions.

[0051] As an alternative implementation, 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.

[0052] Among them, the network management and monitoring platform can identify the host NCR-MT and the slave NCR-MT. The slave NCR-MT needs to receive the signal retransmitted by the host, amplified by the antenna rotator, and perform secondary amplification. The host NCR-MT and the slave NCR-MT establish a corresponding relationship table. After the network management and 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 a preset relationship table.

[0053] In the embodiment of the present application, the corresponding relationship between the host NCR-MT and the slave NCR-MT is stored in a preset relationship table. In this way, the cascading relationship between the host NCR-MT and the slave NCR-MT can be accurately determined through the preset relationship table.

[0054] 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: Determining the location information of the network control relay based on the obtained base station location information and electronic map information in the radio access network; Determining the source base station according to the location information of the network control relay.

[0055] Among them, the base station location information can be understood as the longitude and latitude information of the base station, and the above-mentioned base station location information can be stored in the radio access network RAN; the electronic map information can refer to the information stored in the server corresponding to the electronic map application. The server corresponding to the electronic map application can pre-store the electronic map information of each place, the location information of the base station corresponding to the electronic map information, and the location information of the network control relay corresponding to the electronic map information.

[0056] In the embodiment of the present application, determining the source base station according to the location information of the network control relay can improve the accuracy of the location of the source base station.

[0057] As an optional implementation manner, the determining the source base station according to the location information of the network control relay includes: Determining 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; Sending a fourth control instruction to the NCR-MT and receiving the information of the second candidate base station set replied by the NCR-MT for the fourth control instruction, where the second candidate base station set includes multiple base stations; When the overlap degree 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 degree, determine multiple base stations included in the first candidate base station set or the base stations included in the second candidate base station set as the source base station.

[0058] Among them, the network management and monitoring platform can initially determine the location information of the network control relay according to the longitude and latitude information of the base station and the electronic map information, and then calculate the distance between the network control relay and the 5G source base stations around the network control relay. See Figure 6 , calculate the effective coverage range of each sector of the source base stations around the network control relay according to the projection theorem, so as to initially judge the 5G source base stations around the network control relay, and these source base stations can be listed as the source base stations in set H1, and set H1 can be used to represent the first candidate base station set.

[0059] Among them, the network management and monitoring platform can send a fourth control instruction to the NCR-MT, and the NCR-MT can measure the target information of the source base stations within the preset range of the network control relay according to the fourth control instruction. Then the network management and monitoring platform can receive the target information of the second candidate base station set replied by the NCR-MT for the fourth control instruction, and the above-mentioned second candidate base station set can be referred to as set H2.

[0060] It should be noted that the specific content of the above-mentioned target information in the embodiments of the present application is not limited herein. Optionally, the above-mentioned target information may be the RSRP signal strength.

[0061] Among them, the preset overlap degree can be referred to as threshold T0, and the specific value of threshold T0 is not limited herein. Optionally, threshold T0 can be 80%.

[0062] In the embodiments of the present application, when the overlap degree 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 overlap degree, it indicates that 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 the base stations within the preset range of the NCR-MT at this time. Therefore, multiple base stations included in the first candidate base station set or the base stations included in the second candidate base station set can be determined as the source base station, thereby improving the accuracy of the determination result of the source base station.

[0063] It should be noted that when the overlap degree 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 degree, it indicates that there are base stations outside the preset range among the source base stations measured by the NCR-MT at this time, thus 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-determined, or the preset range can be re-determined alternatively.

[0064] As an alternative implementation, sending the first control instruction to the mobile terminal NCR-MT of the network control relay includes: Obtaining the result information of the access and authentication of the network control relay; When the result information indicates that the access and authentication of the network control relay are passed, sending the first control instruction to the NCR-MT.

[0065] Among them, the specific process of the access and authentication of the network control relay can be referred to the following description: Among them, referring to Figure 7 , the NCR-MT can listen to broadcast messages and system messages through the SIB1 message to obtain the message indicating whether the gNB supports NCR (NCR-support indication in SIB1). During the access process, the NCR indicates NCR information to the source base station (ncr-NodeIndication-r18). After the NCR accesses the gNB, it obtains the message of accessing the AMF, and the AMF provides the authentication information of the NCR to the gNB. The specific access and authentication process can be referred to Figure 7 Steps 1 to 9 shown in

[0066] In the embodiment of the present application, 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, 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.

[0067] As an alternative implementation, after sending the second control instruction corresponding to the judgment result to the NCR-MT, the method further includes: Obtaining the interference signal of the source base station; When the value of the interference signal is greater than the target threshold, sending a fifth control instruction to the NCR-MT, where the fifth control instruction is used to make the NCR-Fwd stop performing the amplification operation and the forwarding operation.

[0068] Among them, the target threshold can be referred to as threshold T5. Optionally, threshold T5 can be equal to -105 dBm.

[0069] Among them, the interference signal may include at least one of a cell interference signal, a cell interference average signal, and an average received interference of each PRB.

[0070] The cell interference signal may refer to N.UL.NI.Avg, and N.UL.NI.Avg may refer to the average value of the uplink and downlink interference noise; The average signal of cell interference can refer to N.UL.NI.Avg.PRB0~PRBxxx, that is, the average of the uplink and downlink interference noise where the PRB is between 0 and XXX. For different cells, the value of XXX is different. For example, for an NR Time Division Duplexing (TDD) 100MHz cell, the PRB range is: PRB0 - PRB272, that is, XXX is 272; The average received interference of each PRB can refer to the hourly granularity and can be obtained by collecting the following performance statistics: The interference noise received per PRB on the uplink (cell level): Statistically calculate the average value N.UL.NI.Avg of the uplink and downlink interference noise detected on each PRB.

[0071] In the implementation manner of this application, when the value of the interference signal is greater than the target threshold, it indicates that the influence of the interference signal is relatively large at this time. Therefore, a fifth control instruction can be sent to the NCR-MT. The fifth control instruction is used to make the NCR-Fwd stop performing the amplification operation and the forwarding operation, thereby reducing the occurrence of errors in the NCR-Fwd performing the amplification operation and the forwarding operation under the interference of the interference signal, and improving the accuracy of the NCR-Fwd performing the amplification operation and the forwarding operation.
