Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to an energy-saving control method and device and storage medium. BACKGROUND

[0002] A 5G (5th Generation Mobile Communication Technology) digital indoor distribution system is composed of a baseband unit (BBU), an intermediate connection device (RHUB) and a micro remote radio unit (Pico RRU). Referring to FIG. 1, a structural schematic diagram of a 5G digital indoor distribution system is shown. The baseband unit is responsible for processing baseband signals. The RHUB is connected with multiple Pico RRUs in a star type, and provides data aggregation and distribution functions for the BBU and the Pico RRU. When transmitting downlink data, the RHUB receives the downlink data sent by the BBU, and transmits the data to the Pico RRU after branch processing. When transmitting uplink data, the RHUB aggregates the uplink data of the Pico RRU and sends the data to the BBU. Generally, one BBU can be connected with more than 10 RHUBs, and each RHUB can be connected with up to 8 Pico RRUs. Figure 1

[0003] The Pico RRU, also known as a pico base station, is mainly used to cover office buildings, shopping malls, stadiums, teaching buildings and other scenarios. These scenarios generally have typical tidal effects, but the number of users is not step-changed but gradually changed. When there are a small number of users in the coverage area, the Pico RRU can be operated in an energy-saving mode.

[0004] Currently, there are two energy-saving schemes for the Pico RRU: symbol shutdown and channel shutdown. Symbol shutdown is to send business data on some time domain symbols and shut down other time domain symbols, thereby achieving energy saving. Channel shutdown is to shut down part of the radio frequency channels, thereby achieving energy saving.

[0005] However, symbol shutdown is operated in units of cells. Generally, a cell has several to tens of Pico RRUs, and symbol shutdown will simultaneously turn on and off all Pico RRUs in the cell, so the granularity of energy-saving control is very coarse. Channel shutdown will cause the coverage range of the Pico RRU to shrink and reduce the transmission efficiency of downlink data, so channel shutdown is only applicable to scenarios with non-busy hours and small estimated business rates.

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 skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Embodiment one

[0035] Referring to Figure 1 , a specific step flowchart of an energy-saving control method provided by the first embodiment of the present application is shown.

[0036] Step 101: The radio frequency channels between the baseband unit and the intermediate wiring device are merged to obtain logical channels between the baseband unit and the intermediate wiring device, and each logical channel corresponds to at least one skin base station.

[0037] Step 102: If there is a first logical channel in the logical channels, the signal strengths of the skin base stations corresponding to the first logical channel are detected; wherein there is an access user in at least one skin base station corresponding to the first logical channel.

[0038] Step 103: If there is a first skin base station in the skin base stations corresponding to the first logical channel, the first skin base station is subjected to symbol off processing; wherein the signal strength of the first skin base station is less than a preset threshold.

[0039] It should be noted that the energy-saving control method provided by the embodiments of the present application is applied to an indoor distribution system, the indoor distribution system includes a baseband unit, an intermediate wiring device and a skin base station, the baseband unit is connected to at least one intermediate wiring device, and each intermediate wiring device is connected to at least one skin base station.

[0040] Taking an example of the baseband unit connecting 3 intermediate wiring devices and each intermediate wiring device connecting 3 skin base stations, referring to Figure 2 , a structural schematic diagram of a digital indoor distribution system is shown. Referring to Figure 2As shown, the digital indoor distribution system includes a baseband unit 11, intermediate connection devices 121-123, and pico base stations 131-136. Baseband unit 11 is connected to intermediate connection devices 121-123, intermediate connection device 121 is connected to pico base stations 131-132, intermediate connection device 122 is connected to pico base stations 133-134, and intermediate connection device 122 is connected to pico base stations 135-136. The baseband unit connects to the intermediate connection devices via a radio frequency channel and accesses the core network via a backhaul interface. Terminal 141 is connected to pico base station 131, terminal 142 is connected to pico base station 134, and terminals 143 and 144 are connected to pico base station 136.

[0041] In the aforementioned digital indoor distributed system, because pico base stations have a transmit power of only a few hundred milliwatts, the coverage of a single pico base station is limited. Therefore, to reduce the need for terminals to switch back and forth between multiple pico base stations within the coverage area of ​​the digital indoor distributed system, the coverage areas of multiple pico base stations are typically combined into a combined cell, allowing terminals to access the network through any pico base station within the combined cell. Each pico base station within the same combined cell can be connected to the same baseband unit via an intermediate connection device.

[0042] For example, refer to Figure 3 As shown in FIG, a schematic diagram of the structure of an indoor distribution system for merging cells is shown. Figure 3 As shown, baseband unit 21 is connected to an intermediate connection device 22, which connects pico base station 231 and pico base station 232. Terminal 241 accesses pico base station 231, and terminal 242 accesses pico base station 232. Because the coverage area of ​​pico base stations is relatively small, and pico base stations 231 and 232 are geographically close, the coverage areas of pico base stations 231 and 232 can be merged into a single cell, forming a merged cell 25.

[0043] In an embodiment of the present invention, in order to further improve the utilization of communication resources, the radio frequency channels between the baseband unit and the intermediate connection device can also be merged. For the sake of distinction, the merged radio frequency channels are called logical channels. Pico base stations connected to the same baseband unit can share the same logical channel. Figure 4 , shows a schematic diagram of the structure of an indoor distribution system after merging RF channels according to an embodiment of the present invention. Baseband unit 31 is connected to an intermediate connection device 32, which is connected to pico base stations 331-334. Pico base stations 331-332 share logical channel L1, while pico base stations 333-334 share logical channel L2.

[0044] The conventional base station system can adopt a channel shutdown mode or a symbol shutdown mode to improve the effective utilization of communication resources. However, due to the volume and weight restrictions, the pico base station in the digital indoor distribution system generally supports only a small number of channels such as 2T2R or 4T4R, and does not support the massive antenna array (MIMO, Massive) technology, and thus cannot adopt the channel shutdown mode to improve the effective utilization of resources. If the symbol shutdown mode is adopted, the combined cells may be shut down, and thus a coverage hole may occur, resulting in that the terminal cannot access the network.

[0045] To solve the above problems, the embodiments of the present application perform energy-saving control judgment in different granularities based on the logical channels and the pico base stations corresponding to the logical channels. Specifically, the logical channels of the indoor distribution system are detected first to determine whether there is a first logical channel, wherein at least one pico base station corresponding to the first logical channel has an access user.

[0046] As an optional embodiment, when the pico base station has an access user, i.e., the terminal connected to the pico base station is in an active state, the terminal will send a random access signal to request the allocation of network resources. However, the signal power of the random access signal is generally low, and thus the user cannot be directly determined to access from which pico base station by analyzing the signal strength corresponding to the pico base station. However, the baseband unit can detect from which logical channel the random access signal is input, and thus in the embodiments of the present application, the first logical channel can be determined by detecting the random access signal, i.e., the first logical channel can include but is not limited to the logical channel having the random access signal.

[0047] Alternatively, at least one pico base station corresponding to the logical channel has an access user, i.e., an access terminal. If the terminal sends a service signal to the baseband unit to transmit service data, the power of the service signal is much higher than the channel noise, and thus the first logical channel can be determined by analyzing the signal strength of each logical channel. In this case, after the first logical channel is determined, the signal strength of the pico base station smaller than a preset threshold can be determined as the first pico base station based on the signal strength change of the service data, and the symbol shutdown processing is performed on the first pico base station to realize energy-saving control, wherein the first pico base station does not have an access user.

[0048] It should be noted that when the terminal accesses the pico base station, the terminal may not transmit service data, but may transmit a random access signal or other signals. In this case, the terminal cannot be determined to access from which pico base station based on the service data. In order to ensure the accuracy of the symbol off, it is necessary to analyze based on other signals. As an example, if there is a user accessing in the pico base station, the pico base station will send SRS (Sounding Reference Signal, uplink sounding reference signal) to the baseband unit for channel quality detection and estimation, whether there is uplink service data transmission or not. The signal power of the SRS signal is much larger than the channel noise, which causes the signal strength corresponding to the pico base station with a user accessing to be greater than the pico base station without a user accessing. Therefore, a preset threshold can be determined according to the signal power of the SRS signal, and the first pico base station can be determined according to the signal strength of each pico base station in the detection logic channel.

[0049] After the first pico base station is determined, the first pico base station can be subjected to symbol off processing to achieve energy saving control and improve the effective utilization of communication resources.

[0050] In an optional embodiment of the present application, the method further comprises:

[0051] If there is a third pico base station in each pico base station corresponding to the first logical channel, the third pico base station is sent service data; wherein the signal strength of the third pico base station is greater than or equal to a preset threshold.

[0052] In each pico base station corresponding to the first logical channel, in addition to the first pico base station, there can be a third pico base station, wherein the third pico base station has an access user, that is, the signal strength of the third pico base station is greater than or equal to a preset threshold. The signal strength detection method of the third pico base station is similar to that of the first pico base station, and the embodiment of the present application will not be described further.

[0053] In order to meet the normal communication service needs of users, the third pico base station is not subjected to symbol off processing, and the third pico base station can normally receive the service data issued by the baseband unit and transmit the service data to the user terminal.

[0054] In an optional embodiment of the present application, the step 101 of merging the radio frequency channel between the baseband unit and the intermediate connection device to obtain the logical channel between the baseband unit and the intermediate connection device comprises:

[0055] Step S11, grouping each pico base station in the indoor distribution system to obtain at least one pico base station group, each pico base station group comprising at least one pico base station;

[0056] Step S12: according to the connection relationship between each skin base station in the skin base station group and the baseband unit, the radio frequency channel between the baseband unit and the intermediate connection device is combined to obtain a logical channel between the baseband unit and the intermediate connection device.

[0057] When the radio frequency channel between the baseband unit and the intermediate connection device is combined, each skin base station connected with the baseband unit can be grouped first, and the radio frequency channel between the baseband unit and the intermediate connection device is combined according to the skin base station group, and one skin base station group shares one logical channel. Of course, other combination processing methods can also be used, and the embodiments of the present application are not limited specifically.

[0058] In an optional embodiment of the present application, the method further comprises:

[0059] Step S21: obtaining the signal strength of each skin base station in the indoor distribution system;

[0060] Step S22: determining the skin base station with the maximum signal strength as the second skin base station;

[0061] Step S23: determining the broadcast signal time slot corresponding to the second skin base station based on the time slot ratio rule;

[0062] Step S24: if the current time matches the broadcast signal time slot, sending service data to the second skin base station.

[0063] The time slot ratio rule is used to limit the transmission time slot corresponding to each type of data and the symbol position in the time slot. Specifically, the time slot corresponding to the subframe of each type of transmission data in the time slot ratio rule is the transmission time slot of the transmission data. For example, in the 5G NR (New Radio) system, the data frame is divided into uplink frame, downlink frame and special frame, the broadcast signal is downlink data, and needs to be transmitted through the downlink frame, therefore, the time slot corresponding to the downlink frame is the broadcast signal time slot of the broadcast signal. The OFDM symbols in the time slot are divided into downlink symbols (downlink, marked as “D”), flexible symbols (flexible, marked as “F”) and uplink symbols (uplink, marked as “U”). Among them, the flexible symbol can be used as a conversion point between uplink and downlink. In the time slot of the downlink frame, the downlink transmission is performed on the “D” and “F” symbols, and in the time slot of the uplink frame, the uplink transmission is performed on the “U” and “F” symbols. Therefore, for the broadcast signal, the broadcast signal time slot is the time slot of the downlink frame, and the symbol position is the position corresponding to the “D” and “F” symbols in the time slot of the downlink frame.

[0064] In the embodiment of the present application, after the eligible first skin base station in the indoor distribution system is processed for symbol-off according to the foregoing steps 101 to 103, the signal strength of each skin base station is still monitored in real time, so that the uplink / downlink power amplifier of the skin base station with a new access user is increased to transmit service data. Specifically, the skin base station with the largest signal strength in the indoor distribution system, i.e., the second skin base station, is determined as the skin base station for user access. During the symbol-off processing of the skin base station, the skin base station can still normally receive the broadcast signal transmitted by the baseband unit, so as to allow user access. It should be noted that the broadcast signal is transmitted according to the broadcast signal time slot in the time slot allocation rule, i.e., the broadcast signal is transmitted only in the broadcast signal time slot, and no broadcast signal is transmitted in other time slots. In the embodiment of the present application, service data is transmitted to the second skin base station in the broadcast signal time slot, and no service data is transmitted in other time slots. In this way, the second skin base station can continue to be in the energy-saving state in other time slots, thereby further improving the effective utilization of communication resources.

[0065] In an optional embodiment of the present application, the method further comprises:

[0066] Step S31, determining a symbol-off time slot corresponding to the baseband unit;

[0067] Step S32, if there is a second logical channel in the logical channel corresponding to the baseband unit, processing each skin base station corresponding to the second logical channel for symbol-off according to the symbol-off time slot; wherein, there is no access user in each skin base station corresponding to the second logical channel.

[0068] It should be noted that there can be a second logical channel in the indoor distribution system, wherein there is no access user in each skin base station corresponding to the second logical channel. In other words, the logical channel in the indoor distribution system except the first logical channel is the second logical channel. For the second logical channel, the second logical channel can be directly processed for symbol-off, i.e., each skin base station corresponding to the second logical channel is uniformly processed for symbol-off. The second logical channel can be determined by using a similar determination method as the first logical channel, and the embodiment of the present application will not be described further.

[0069] The symbol-off time slot can be determined according to the communication resource occupation characteristics of the coverage area of the indoor distribution system. For example, for an office building, the communication resource occupation rate is higher during the day and lower at night, so the symbol-off processing can be performed on each skin base station corresponding to the office building at night. For example, 22:00-06:00 can be taken as the symbol-off time slot corresponding to the office building.

[0070] Optionally, the symbol-off time slot can also be other time slots except the broadcast signal time slot. The downlink signal usually includes a broadcast channel and a service channel, and for each skin base station without access users, the broadcast channel can not be subjected to the off processing, and the service channel is subjected to the symbol-off processing. The broadcast signal in the broadcast channel can be only transmitted in the broadcast signal time slot, and not transmitted in other time slots, and therefore, for the skin base station without access users, other time slots except the broadcast signal time slot can be directly subjected to the symbol-off processing, that is, other time slots except the broadcast signal time slot are taken as the symbol-off time slot, so as to maximize the utilization of the communication resource.

[0071] In conclusion, the embodiment of the present application combines the radio frequency channels between the baseband unit and the intermediate connection device in the indoor distribution system, so that multiple skin base stations share the same combined logical channel, and the utilization of the communication resource is improved. Moreover, the embodiment of the present application analyzes from the two levels of the logical channel and the skin base station, accurately locates the skin base station accessed by the user based on the signal strength, subjects the first skin base station without user access to the symbol-off processing, avoids the coverage hole caused by the symbol-off processing in the unit of the cell in the traditional symbol-off processing, ensures the skin base station with user access in the normal working state, and improves the accuracy of the energy-saving control.
