Description

Technical Field

[0001] The present disclosure generally relates to the field of artificial intelligence, and more specifically, to repeater energy saving. Background Art

[0002] A repeater is a co-frequency amplification device, and is a radio transmission transfer device that enhances the signal during wireless communication transmission. The main function of a repeater is to enhance the signal power of the radio frequency. Based on the function implementation method, it is divided into wireless repeaters and fiber repeaters. In the downlink, the wireless repeater obtains the signal from the existing coverage area by the donor antenna, isolates the signal through the filter, amplifies the filtered signal and transmits it to the area to be covered; the fiber repeater couples the wireless signal from the base station and enters the optical near-end machine. Through electro-optical conversion, the electrical signal is converted into an optical signal, which is input from the optical near-end machine to the optical fiber, and transmitted to the optical remote machine through the optical fiber. The optical remote machine converts the optical signal into an electrical signal, enters the RF unit for amplification, and the signal is sent to the transmitting antenna after amplification to cover the target area. In the uplink path, the signal of the terminal in the coverage area is processed by the uplink amplification link in the same working mode and then transmitted to the corresponding base station, thereby achieving signal transmission between the base station and the terminal.

[0003] The power consumption of a repeater is mainly generated by the power amplifier, which accounts for more than 70% of the total power consumption of the repeater. Moreover, the power amplifier currently used will still have a large static current when there is no user or signal input, which will generate a large amount of useless power consumption, and then reduce the efficiency and economic benefits of the repeater. Therefore, how to reduce the power consumption of the repeater has always been a difficult problem in this field. Existing energy-saving technologies are mainly achieved by intelligently shutting down the remote radio unit (RRU) channel and orthogonal frequency division multiplexing (OFDM) symbols, but there is no energy-saving strategy for repeaters.

[0004] In view of this, the present invention aims to propose a novel repeater station energy-saving method and device capable of reducing the power consumption of the repeater station. Summary of the invention

[0015] The following detailed description is made with reference to the accompanying drawings, and the following detailed description is provided to assist in a comprehensive understanding of the various exemplary embodiments of the present disclosure. The following description includes various details to assist in understanding, but these details are considered to be examples only and not to limit the present disclosure, which is defined by the appended claims and their equivalents. The words and phrases used in the following description are only used to enable a clear and consistent understanding of the present disclosure. In addition, for the sake of clarity and brevity, descriptions of well-known structures, functions, and configurations may be omitted. Those of ordinary skill in the art will recognize that various changes and modifications may be made to the examples described herein without departing from the spirit and scope of the present disclosure.

[0016] Next, we will refer to Figures 1 to 3 The method and device for energy saving of a repeater according to the present invention are described in detail.

[0017] Figure 1 A schematic diagram 100 of the association relationship between a remote radio unit (RRU), a repeater and a terminal is shown.

[0018] like Figure 1 As shown, RRU 110 transmits the digital signal to the repeater RF unit of repeater 120 via optical fiber transmission. Repeater 120 receives the RF signal from RRU 110 and sends the RF signal to terminal 130 via an antenna.

[0019] Specifically, the repeater 120 performs signal power enhancement and conversion on the RF signal from the RRU 110, receives the low-power downlink signal of the RRU 110 to the repeater signal receiver through the forward antenna (i.e., the donor antenna), amplifies the useful signal through the low-noise amplifier, suppresses the noise signal in the signal, and improves the signal-to-noise ratio (S / N); then it is down-converted to an intermediate frequency signal, filtered by a filter, amplified by the intermediate frequency, and then frequency-shifted up-converted to RF, amplified by a power amplifier, and transmitted to the terminal 130 by the backward antenna (retransmission antenna).

[0020] In addition, the repeater 120 can also use the backward antenna to receive the uplink signal of the terminal 130, and process it by the uplink amplification link along the reverse path: that is, through the low noise amplifier, down converter, filter, intermediate amplifier, up converter, power amplifier and then transmit it to the RRU 110. Thus, two-way communication between the RRU 110 and the terminal 130 is realized.

[0021] Although not shown, it should be noted that the above communication process between RRU 110, repeater 120 and terminal 130 is only for illustrative purposes and does not constitute a limitation to the present invention. Any other communication process and processing between RRU 110, repeater 120 and terminal 130 is applicable to the present invention.

[0022] Figure 2A schematic diagram 200 of a method for energy saving in a repeater according to an embodiment of the present disclosure is shown.

[0023] As shown in FIG. 200 , at step S202 , the correspondence between the RRU and the repeater connected to the RRU is extracted.

[0024] In some aspects of the embodiments of the present disclosure, the logical correspondence between the RRU and the repeater connected to the RRU is extracted using relevant base station configuration data in the integrated network management platform.

[0025] In addition, the integrated network management platform can also be used to extract the corresponding relationship between the RRU and the service scope (such as a cell, a unit building, etc.) and the corresponding relationship between the repeater and the service scope.

[0026] Next, at step S204, load-related parameters of the RRU during the first time period and user-related parameters reported by the terminal are acquired.

[0027] In some aspects of the embodiments according to the present disclosure, the first time period may be one day, several days, one week, several weeks, one month, several months, etc.

[0028] For example, base station configuration data, base station performance parameters, etc. are obtained in real time from the northbound interface, and then the load-related parameters of the RRU are obtained based on the base station configuration data, the base station performance parameters, etc. In some aspects of the embodiments of the present disclosure, the load-related parameters of the RRU include but are not limited to occupied physical resource blocks PRBs, traffic load, flow load, and the number of access users in the RRU.

[0029] In addition, user-related parameters may also be received from the terminal device. In some aspects of the embodiments of the present disclosure, the user-related parameters reported by the terminal include but are not limited to reference signal received power (RSRP), timing advance (TA), etc.

[0030] Next, at step S206, statistics are collected and determined to determine the first time that the load-related parameter of the RRU is lower than a first predetermined threshold.

[0031] In some aspects according to the present disclosure, through big data analysis, a first predetermined threshold is set based on the periodic load of each RRU in the entire network, the periodic load of the repeater under each RRU, and the number of access users in each RRU.

[0032] In addition, the first predetermined threshold may be one or a combination of thresholds consisting of multiple thresholds. For example, when the traffic load is selected as the judgment criterion, a predetermined threshold may be set, namely, the first predetermined threshold related to the traffic load (for example, 0.5Erl). When the traffic load of the RRU is lower than the first predetermined threshold related to the traffic load, the time node is recorded and the first time is determined to start. In addition, for example, when the two parameters of traffic load and flow load are selected as the judgment criterion, in addition to the first predetermined threshold related to the traffic load, the first predetermined threshold related to the flow load (for example, 20Mbps) may also be set. For example, when the traffic load of the RRU is lower than the first predetermined threshold related to the traffic load, or the flow load of the RRU is lower than the first predetermined threshold related to the flow load, the time node is recorded and the first time is determined to start.

[0033] In addition, the above only uses the traffic load and flow load of the RRU as examples to illustrate the determination at the first time, which does not constitute a limitation on the present invention. For example, parameters such as the occupied physical resource blocks PRBs and the number of access users in the RRU can also be used as determination criteria, and the first predetermined threshold value related to the occupied physical resource blocks in the RRU and the first predetermined threshold value related to the number of access users are set accordingly. In other words, as long as it can be used to determine the load level of the RRU, any parameter is applicable to the embodiments according to the present disclosure.

[0034] In addition, as described with reference to the traffic load and flow load, as long as any one of the occupied physical resource blocks PRB, traffic load, flow load and number of access users in the RRU is lower than the corresponding first predetermined threshold, it is determined that the first time starts.

[0035] Furthermore, the first predetermined threshold of the load-related parameter of the RRU is not constant but can be set as needed, for example, can be set differently according to the application scenarios, working days, weekends, seasons, etc. of the RRU and its corresponding repeater.

[0036] In addition, although not shown, in some aspects of the embodiments of the present disclosure, the load-related parameters of the RRU during the second time period and the user-related parameters reported by the terminal can also be obtained, and the judgment of the first time can be updated based on the load-related parameters of the RRU during the second time period and the user-related parameters reported by the terminal.

[0037] That is, the determination of the first time can be updated in different time periods based on the latest RRU load-related parameters and user-related parameters. For example, when one week is selected as a cycle, based on the RRU load-related parameters and user-related parameters of the first week, 22:00 on Friday of the first week is determined as the first time, and in the second week, based on the RRU load-related parameters and user-related parameters of the second week, 22:10 on Friday of the second week is determined as the first time. In other words, the change of the first time depends on the periodic changes of the RRU load-related parameters and user-related parameters that actually occur during different statistical periods.

[0038] Next, at step S208, at the first time when the load-related parameter of the RRU is lower than the first predetermined threshold, based on the user-related parameter reported by the terminal, the active repeater among the repeaters under the RRU is determined. In aspects of the embodiments of the present disclosure, the repeater generating the traffic is referred to as the active repeater.

[0039] For example, whether the traffic in the RRU comes from a repeater and which repeater it comes from may be determined based on the reference signal received power (RSRP) and timing advance (TA) information of the user-level MR.

[0040] Next, at step S210, the inactive repeaters except the active repeaters among the repeaters under the RRU are turned off. In aspects of the embodiments of the present disclosure, the repeaters that do not generate traffic are referred to as inactive repeaters.

[0041] In addition, for example, the control device determines whether there is a repeater network manager based on the completeness determination of the repeater network manager data (see step S212).

[0042] In some aspects of the embodiments of the present disclosure, when there is a repeater network manager, at the first time, the control device sends an instruction to the repeater network manager to shut down the inactive repeater (as shown in step S214). For example, the control device determines the instruction and converts the instruction into a network management operation instruction recognizable by the repeater network manager, and then sends the instruction to the repeater network manager side using an interface to perform relevant operations on the inactive repeaters in the corresponding time period, and presents a prompt of "energy saving shutdown" on the repeater network manager so that maintenance personnel can grasp the equipment operation status.

[0043] In some aspects of the embodiments of the present disclosure, when there is no repeater network management, at the first time, the control device directly controls the shutdown operation of the inactive repeater and notifies the monitoring and maintenance personnel of the operating status of the repeater (as shown in step S216). For example, the control device uses the Internet of Things technology to transmit instructions to the intelligent air switch to control the repeater.

[0044] In addition, although not shown, in some aspects of the embodiments according to the present disclosure, the second time when the load-related parameters of the RRU are lower than the second predetermined threshold is counted and determined, wherein the second predetermined threshold is lower than the first predetermined threshold, and at the second time when the load-related parameters of the RRU are lower than the second predetermined threshold, the RRU and all the repeaters under the RRU are shut down.

[0045] In some aspects of the present disclosure, through big data analysis, a second predetermined threshold is set based on the periodic load of each RRU in the entire network, the periodic load of the repeater under each RRU, and the number of access users in each RRU.

[0046] For example, using the traffic load and flow load as the judgment criteria, the second predetermined threshold value related to the traffic load (e.g., 0.1Erl) and the second predetermined threshold value related to the flow load (e.g., 2Mbps) can be set respectively. For example, when the traffic load of the RRU is lower than the second predetermined threshold value related to the traffic load, or the flow load of the RRU is lower than the second predetermined threshold value related to the flow load, it is determined that the second time starts, and the RRU and all the repeaters under the RRU are turned off.

[0047] In addition, it should be noted that, similar to the above description of the second predetermined threshold, the above-mentioned traffic load and flow load are also shown only as examples and do not constitute a limitation to the present invention.

[0048] In addition, although not shown, in some aspects of the embodiments of the present disclosure, the third time to turn on the RRU and the repeater under the RRU is determined based on statistical analysis of the load-related parameters of the RRU and the user-related parameters reported by the terminal.

[0049] Regarding the start-up operation of the repeater, when there is a repeater network manager, the control device sends an instruction to the repeater network manager to start the repeater, and presents an "intelligent recovery" prompt on the repeater network manager so that maintenance personnel can understand the equipment operation status. When there is no repeater network manager, at the third time, the control device directly controls the start-up operation of the repeater and notifies the monitoring and maintenance personnel of the operation status of the repeater.
