In the base station system, a plurality of remote devices are connected with a convergence device in a star cascade mode, the convergence device is connected with a baseband device in a star cascade mode, and the baseband device is connected with a core network. The far-end equipment and the convergence equipment adopt network cables as transmission media, and the convergence equipment supplies power to the far-end equipment through a Power Over Ethernet (POE) port. In a digital indoor distribution system, cells served by a plurality of remote devices are generally combined into one cell (referred to as a combined cell). And the terminal positioned in the merging cell can access the network through any remote equipment corresponding to the merging cell.
The traditional base station system can adopt a channel switching-off mode or a cell switching-off mode to improve the effective utilization rate of communication resources.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.
With the development of mobile internet technology, more and more services will be generated indoors, and the requirement of indoor network coverage capability is higher and higher. Accordingly, a digital indoor distribution system is produced.
A typical architecture of the digital indoor distribution system is a base station system adopting a three-level distributed architecture, and includes a baseband processing unit (BBU) (also called baseband device), a HUB unit (RRU-HUB, RHUB, also called convergence device), and a Radio Remote Unit (RRU) (also called remote device). The baseband device is connected with at least one convergence device, and each convergence device is connected with at least one remote device. The terminal can access the digital indoor distribution system through any remote equipment.
Taking a baseband device connected to 3 convergence devices, each convergence device connected to 3 remote devices as an example, fig. 1 shows a structure of a digital indoor distribution system. Referring to fig. 1, the digital indoor distribution system includes a baseband device 11, a convergence device 121 and 123, and a remote device 131 and 139. The baseband device 11 is connected to the convergence device 121 and 123, the convergence device 121 is connected to the remote device 131 and 133, the convergence device 122 is connected to the remote device 134 and 136, and the convergence device 123 is connected to the remote device 137 and 139. The baseband device 11 is connected to the convergence device through the fronthaul interface, and is accessed to the core network through the backhaul interface. Terminal 141 accesses remote device 133, terminal 142 accesses remote device 135, and terminal 143 and terminal 144 accesses remote device 137.
In the digital indoor distribution system, the transmission power of the remote device is in the order of hundreds of milliwatts, so the coverage area of a single remote device is small. Therefore, in order to reduce the switching of the terminal between multiple remote devices in the coverage area of the digital indoor distribution system, the multiple remote devices are generally merged into a merged cell, so that the terminal can access the network through any remote device in the merged cell.
For example, referring to fig. 2, a baseband device 21 is connected to a convergence device 22. Aggregation device 22 connects remote device 231 and remote device 232. Terminal 241 accesses remote device 231 and terminal 242 accesses remote device 242. Since the coverage area of the remote device is small and the geographic locations of the remote device 231 and the remote device 232 are relatively close, the remote device 231 and the remote device 232 can be combined into the same cell to form the combined cell 25.
The traditional base station system can adopt a channel switching-off mode or a cell switching-off mode to improve the effective utilization rate of communication resources. However, due to the limitations of volume and weight, the remote devices in the digital indoor distribution system generally only support a small number of channels, such as 2T2R or 4T4R, and do not support a large-scale antenna array (massive MIMO) technology, and the effective utilization rate of communication resources cannot be improved by using a channel shutdown method. However, by using the cell shutdown method, the merged cell may be shut down, and thus, a coverage hole may occur, which may result in that the terminal cannot access the network.
In order to solve the above problems, the present application provides an energy saving method and apparatus for a digital indoor distribution system, which are applied to the digital indoor distribution system. The energy-saving method comprises the following steps: the baseband device obtains at least one signal strength measured by a first terminal of the first remote device and an identification of the at least one remote device. And the baseband equipment determines the identifier of the remote equipment corresponding to the signal strength with the maximum value in the at least one signal strength as the identifier of the second remote equipment. Wherein the identity of the second remote device is different from the identity of the first remote device. The baseband device then sends a first message to each remote device connected to the baseband device instructing a second remote device to increase output power. And finally, the baseband equipment sends a second message to the first convergence equipment to indicate the first convergence equipment to disconnect the first convergence equipment from the first remote equipment. Wherein the first message includes an identification of the second remote device and a power boost instruction. The second message includes an indication of the connection interruption and an identification of the first remote device. In this way, the first terminal can be re-accessed from the first remote device to the second remote device. Therefore, the method and the device can improve the effective utilization rate of the communication resources of the digital indoor distribution system by utilizing the mode that the first convergence device is disconnected with the first remote device.
In particular implementations, the energy saver of the digital indoor distribution system of the present application has the components shown in fig. 3.

The energy saving method of the digital indoor distribution system according to the embodiment of the present application is described below with reference to the digital indoor distribution system shown in fig. 1, the merging cell shown in fig. 2, and the energy saving device of the digital indoor distribution system shown in fig. 3.
Fig. 4 is a schematic flowchart of an energy saving method of a digital indoor distribution system according to an embodiment of the present application. Referring to fig. 4, the energy saving method of the digital indoor distribution system includes the following steps.
401. The baseband device obtains at least one signal strength and an identification of at least one remote device.
Wherein the at least one signal strength is obtained by the first terminal measuring a test signal of the at least one remote device. The at least one remote device includes a first remote device. The first remote device is: and the remote equipment which has the minimum terminal occupation ratio and the terminal occupation ratio smaller than a first preset threshold is connected with the baseband equipment, and the first remote equipment provides service for the first terminal.
The identification of the remote devices is used for distinguishing and identifying each remote device, and the identification of different remote devices is different.
Firstly, before the baseband device obtains at least one signal strength and an identifier of at least one remote device, the baseband device needs to configure a test signal for each remote device connected with the baseband device, and issue a first mapping relationship after generating the first mapping relationship according to the configured test signal and the identifier of the remote device. The identifier of the remote device may be pre-stored in the remote device, for example, the device number of the remote device. The identifier of the remote device may also be that the aggregation device distinguishes and identifies different remote devices based on the port of each remote device, for example, the aggregation device uses the port number connected to the remote device as the identifier of the remote device, and sends the port number to the corresponding remote device. Each remote device corresponds to one identifier, and the identifiers of any two remote devices are different from each other.
Specifically, first, the baseband device configures a test signal for each remote device connected to the baseband device, where the test signals of any two remote devices are orthogonal. Illustratively, when the baseband device configures a test signal for each remote device, it is specified that each test signal occupies a certain number of time-frequency Resources (REs), and REs occupied by test signals of different remote devices are staggered in time domain or frequency domain position, so as to implement orthogonality of test signals of any two remote devices. And then, the baseband device generates a first mapping relation by the identification of the remote device and the configured test signal, and sends the first mapping relation to each remote device and the terminal providing the service for the baseband device. The first mapping relationship includes a corresponding relationship between the identifier of the remote device and the test signal, and specifically, the first mapping relationship may be embodied in a table form. And finally, after the target remote device acquires the first mapping relation, generating a second test signal according to the first mapping relation, and then sending the first mapping relation to a terminal for providing service to the target remote device by the target remote device. The target remote device is any remote device connected with the baseband device.
For example, the baseband device is connected to a convergence device, the convergence device is connected to a first remote device and a second remote device, the first terminal, the second terminal, and the third terminal are all within the coverage range of the first remote device and the second remote device, and in a scenario where the first terminal is accessed to the first remote device, and the second terminal and the third terminal are accessed to the second remote device, as shown in fig. 5, the baseband device may implement issuing of the first mapping relationship by performing the following steps a1 to a 5.
A1, configuring a test signal by the baseband device, and generating a first mapping relation. Specifically, first, the baseband device configures a first test signal for a first remote device, and configures a second test signal for a second remote device. Wherein the first test signal and the second test signal are orthogonal. Secondly, the baseband device generates a first mapping relation by enabling the identification of the first remote device to correspond to the first test signal and enabling the identification of the second remote device to correspond to the second test signal.
A2, the baseband device sends the first mapping relation to the sink device. The baseband device sends the first mapping relationship to the sink device, and simultaneously carries the identifier of the baseband device and the identifier of the sink device.
A3, the aggregation device sends the first mapping relation to all remote devices connected with the aggregation device. The convergence device sends the first mapping relation to the remote device, and carries the identifier of the convergence device.
And A4, after the remote device determines that the first mapping relation is received, the first remote device generates a first test signal according to the first mapping relation, and the second remote device generates a second test signal according to the first mapping relation.
A5, the remote device sends the first mapping relation to the terminal one. And the far-end equipment sends the first mapping relation to the second terminal and the third terminal.
Secondly, the baseband device needs to determine the first remote device. Specifically, the baseband device may determine the first remote device by performing the following steps B1-B3.
B1, the baseband device acquires the number of terminals connected with each remote device connected with the baseband device.
Specifically, the method for the baseband device to obtain the number of terminals connected to each remote device connected to the baseband device may be that the terminal actively reports the terminal identifier after accessing the remote device, and then the baseband device counts the terminal identifier reported by each remote device to obtain the number of terminals connected to each remote device.
For example, the baseband device is connected to a convergence device, the convergence device is connected to a first remote device and a second remote device, and the first terminal, the second terminal, and the third terminal are all within the coverage range of the first remote device and the second remote device. In a scenario where the first terminal accesses the first remote device, the second terminal and the third terminal access the second remote device, as shown in fig. 6, the baseband device may implement obtaining of the number of terminals accessed by each remote device by executing the following steps b1 to b 3.
b1, accessing the first terminal to the first remote device, and reporting the terminal identifier of the first terminal to the first remote device; the second terminal is accessed to the second remote device, and reports the terminal identification of the second terminal to the second remote device; and the third terminal accesses the second remote equipment and reports the terminal identification of the third terminal to the second remote equipment. When reporting the terminal identifier to the remote device, the terminal can report the terminal identifier through an attach request message or other uplink air interface messages.
b2, the remote device reports the terminal identifier of the first terminal and the identifier of the first remote device to the convergence device; and the far-end equipment reports the terminal identification of the second terminal, the terminal identification of the third terminal and the identification of the second far-end equipment to the convergence equipment.
b3, the convergence device packs and sends the terminal identifier of the first terminal, the identifier of the first remote device and the identifier of the convergence device to the baseband device; and the convergence device packages and sends the terminal identification of the second terminal, the terminal identification of the third terminal, the identification of the second remote device and the identification of the convergence device to the baseband device. Thus, through the multiple reporting in fig. 6, the baseband device can count that the remote device i is connected to the terminal i, and the number of connected terminals is 1. The second remote device is connected with a second terminal and a third terminal, and the number of the connected terminals is 2.
Optionally, the method for the baseband device to obtain the number of terminals connected to each of the at least two remote devices may also be that the baseband device sends a terminal number statistics instruction to the remote device, and then the remote device directly reports the number of terminals connected to the baseband device. However, this case involves the scheduling of multiple instructions.
And B2, the baseband equipment calculates the terminal occupation ratio of each remote equipment according to the acquired terminal number.
For the third remote device, the terminal occupancy of the third remote device is a ratio of the number of terminals connected to the third remote device to the number of all the obtained terminals, and the third remote device is any one remote device connected to the baseband device. For example, a convergence device is connected below the baseband device, and a first remote device and a second remote device are connected below the convergence device. The baseband device counts that the number of terminals accessed by the first remote device is 1, and the number of terminals accessed by the second remote device is 2. The terminal occupation ratio of the remote device one is
Figure BDA0002487761170000111
The terminal occupation ratio of the remote equipment II is
Figure BDA0002487761170000112
B3, the baseband device determines the first remote device.
And the terminal occupation ratio of the first remote equipment is in the calculated terminal occupation ratios, and the numerical value is minimum and is smaller than a first preset threshold. The first preset threshold is preconfigured, and may be a default value, a preset value, or a value rewritten by a manager, for example. For example, the first preset threshold is preconfigured to
Figure BDA0002487761170000121
The terminal occupation ratio of the remote equipment I is
Figure BDA0002487761170000122
The terminal occupation ratio of the remote equipment II is
Figure BDA0002487761170000123
The terminal occupation ratio of the remote device one is minimum and less than
Figure BDA0002487761170000124
The remote device is thus determined to be the first remote device.
And thirdly, after the baseband equipment determines the first remote equipment, the baseband equipment sends a third message to each remote equipment connected with the baseband equipment. For the fourth remote device, the third message is used to instruct the fourth remote device to send a first test signal, and the first test signal is generated by the fourth remote device after the baseband device configures the fourth remote device. The fourth remote device is any remote device connected with the baseband device. Specifically, after determining the first remote device, the baseband device sends a fifth message to all sink devices connected to the baseband device, where the fifth message carries a test signal sending instruction, an identifier of the baseband device, and an identifier of the sink device. After the second aggregation device receives the fifth message, if it is determined that the identifier of the aggregation device carried in the fifth message includes the identifier of the second aggregation device, the second aggregation device sends a third message to a remote device connected to the second aggregation device, where the second aggregation device is any one of all aggregation devices connected to the baseband device. The third message carries a test signal sending instruction and an identifier of the second aggregation device, and is used for instructing each remote device connected with the second aggregation device to start to periodically send a respective test signal.
And finally, the baseband equipment acquires the signal strength of each test signal measured by the first terminal and the identification of the remote equipment corresponding to each test signal. The first remote equipment provides service for the first terminal. Specifically, after receiving the first mapping relationship, the first terminal periodically measures the signal strength of each test signal, and actively reports the measured signal strength of each test signal and the identifier of the remote device corresponding to each test signal to the baseband device. Further specifically, the first terminal first sends the signal strength of each test signal and the identifier of the remote device corresponding to each test signal to the first remote device, and then the first remote device forwards the signal strength and the identifier of the remote device corresponding to each test signal to the first aggregation device, and the first aggregation device forwards the signal strength and the identifier of the remote device to the baseband device, thereby completing the whole reporting process.
402. The baseband device determines an identity of the second remote device based on the at least one signal strength and the identity of the at least one remote device.
The identifier of the second remote device is the identifier of the remote device corresponding to the target signal strength in the identifiers of the at least one remote device. The target signal strength is the signal strength with the largest value in at least one signal strength. The identity of the second remote device is different from the identity of the first remote device. That is, the baseband device determines the remote device corresponding to the signal strength with the maximum value except the signal strength corresponding to the first remote device as the second remote device.
403. The baseband device transmits a first message to each remote device connected to the baseband device.
Specifically, the first message includes an identification of the second remote device and a power boost instruction. The first message is used to instruct the second remote device to increase the output power. The power boost value is pre-configured, and may be, for example, a default fixed value, a difference between a maximum transmit power supported by the remote device and a current transmit power, or a value re-written by a manager.
404. And the target remote equipment acquires the first message, and if the identification of the second remote equipment is determined to be the same as the identification of the target remote equipment, the target remote equipment improves the output power according to the power boosting instruction.
Optionally, if the target remote device determines that the identifier of the second remote device is different from the identifier of the target remote device, the first message is discarded.
405. And the baseband equipment sends a second message to the first aggregation equipment.
Specifically, the second message is used to instruct the first aggregation device to disconnect from the first remote device. The second message includes a connection interruption indication and an identification of the first remote device.
Further specifically, after determining that the second message is received, the first aggregation device closes the port connected to the first remote device, so that the first remote device is in the deprecated state and does not receive or transmit any signal any more.
Optionally, after the first convergence device closes the port connected to the first remote device, the present application further provides a method for the baseband device to reestablish the connection with the first remote device, including the following steps.
And S1, the baseband equipment acquires the signal strength of the test signal of the second remote equipment measured by the second terminal.
And the second remote equipment provides service for the second terminal. Specifically, the method for the baseband device to obtain the signal strength of the test signal of the second remote device measured by the second terminal may refer to the method for the baseband device to obtain the signal strength of each test signal measured by the first terminal and the identifier of the remote device corresponding to each test signal in step 401.
And S2, the baseband device calculates the weak coverage ratio of the second remote device according to the acquired signal strength.
The weak coverage ratio is a ratio of the number of the target terminals to the number of the second terminals, and the signal strength of the test signal of the second remote device measured by the target terminal is smaller than a second preset threshold.
And S3, if the weak coverage ratio is greater than a third preset threshold, the baseband device sends a fourth message to the first aggregation device to indicate that the first aggregation device is connected with the first remote device.
Wherein the fourth message comprises the connection establishment indication and the identity of the first remote device.
Specifically, after determining that the fourth message is received, the first aggregation device opens a port connected to the first remote device, so that the first remote device is in a restart state and starts to receive and transmit an air interface signal.
In summary, in the energy saving method for the digital indoor distribution system provided by the present application, on the basis that the first remote device provides a service for the first terminal (at this time, the first aggregation device is connected to the first remote device), if the baseband device determines, according to the obtained signal strength (measured by the first terminal of the first remote device) and the identifier of the remote device, that the remote device corresponding to the largest signal strength among all signal strengths except the first remote device is used as the second remote device, the baseband device instructs the second remote device to increase the transmission power, and instructs the first aggregation device to disconnect from the first remote device. In this way, the first terminal can be re-accessed from the first remote device to the second remote device. Firstly, the baseband device makes the first remote device in a service quit mode by using the mode that the first convergence device is disconnected from the first remote device, and improves the effective utilization rate of the communication resources of the digital indoor distribution system by adaptively controlling the working state of the remote device. And secondly, determining second remote equipment by using the test signal, and improving the output power of the second remote equipment to make up for a coverage hole after the first remote equipment is turned off. The coverage capability of the system after the first remote device is turned off can be further improved. And thirdly, when the weak coverage proportion of the second far-end equipment is increased, the first far-end equipment can be restored to the normal working state in a mode of conducting the connection between the first convergence equipment and the first far-end equipment, so that the terminal in the weak coverage area of the second far-end equipment is accessed to the first far-end equipment, and the coverage capability of the digital indoor distribution system is improved.
