Description
Technical Field
Embodiments of the present disclosure relate generally to the field of communications, and more particularly, to a method for open-station of multiple remote radio units, a baseband unit, a communication system, and a computer storage medium.
Background
Current wireless communication system sites typically include a Base Band Unit (BBU) and a plurality of Remote Radio Units (RRUs). The baseband unit is used for encoding, modulating and other processing of communication data to generate a signal to be transmitted and transmitting the signal to be transmitted to the far-end radio frequency unit. The remote radio frequency unit is used for transmitting a signal to be transmitted through the antenna. The maximum power consumption of the whole station can reach several kilowatts. The power consumption of the baseband unit is usually stable, but the power consumption of the remote radio frequency unit usually changes along with the service change, and the power consumption is high when the service load is high and low when the service load is low.
After the station is powered on, the remote rf unit needs to perform calibration and standing wave detection (also called open-station). In this process, the test signal needs to be transmitted at a higher transmit power. At this time, if all the remote rf units transmit the test signal simultaneously, the power consumption of the station may reach or approach the maximum power consumption level of the whole station. In a site with a heavy load on a part of power grid or in an area with a less stable power grid, the power supply of the site may not meet the requirement of the maximum load, so that the power supply unit trips or resets, and the whole site is restarted. Due to the consistency of software and hardware of the plurality of remote rf units, the following phenomena may recur: the method comprises the steps of powering on and starting a station, simultaneously transmitting test signals by a plurality of remote radio frequency units, calibrating power overload, and powering off, so that the station is repeatedly started all the time and cannot provide services.

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The term "include" and variations thereof as used herein is meant to be inclusive in an open-ended manner, i.e., "including but not limited to". Unless specifically stated otherwise, the term "or" means "and/or". The term "based on" means "based at least in part on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions are also possible below.
As described above, in the conventional scheme, the calibration and standing wave detection performed simultaneously by all the remote rf units result in high power supply load of the whole site, and the power supply is liable to trip in an unstable or insufficient power supply area of the power grid. In addition, the consistency of software and hardware of the remote radio frequency units is high, which may cause the station to repeatedly perform the starting, calibrating and power-down processes after tripping, and thus service cannot be provided.
To address, at least in part, one or more of the above problems, as well as other potential problems, example embodiments of the present disclosure propose a solution for the outstation of multiple remote radio units. In this scheme, the baseband unit, in response to receiving a plurality of ready messages from a plurality of remote radio units coupled to the baseband unit, obtains open-site configuration data for the plurality of remote radio units, the open-site configuration data indicating a plurality of sets of remote radio units into which the plurality of remote radio units are divided and a plurality of open-site batches associated with the plurality of sets of remote radio units, the open-site including calibration and standing wave detection. The baseband unit then sends an open start message to a first set of remote radio units from the plurality of sets of remote radio units, the first set of remote radio units associated with the first open lot. The baseband unit, in response to receiving the set of complete outbound messages from the first set of remote radio units, then sends an initiate outbound message to a second set of remote radio units from the plurality of sets of remote radio units, the second set of remote radio units associated with a second outbound batch, the second outbound batch located after the first outbound batch. According to the embodiment of the disclosure, the plurality of remote radio units coupled to the baseband unit are divided into a plurality of open-station batches, and the next batch of open stations is started after the previous batch of open stations is completed, so that the instantaneous total power consumption of the open stations of the plurality of remote radio units coupled to the baseband unit can be reduced.
Hereinafter, specific examples of the present scheme will be described in more detail with reference to the accompanying drawings.
Fig. 1 shows a schematic diagram of an example of a communication system 100 according to an embodiment of the present disclosure. The communication device 100 may include a baseband unit 110 and a plurality of remote radio units 120-1 to 120-n (hereinafter referred to as remote radio units 120 collectively) coupled to the baseband unit 110, where n is greater than or equal to 2.
The open-site configuration data 130 may indicate a plurality of remote radio unit sets into which the plurality of remote radio units 120 are divided and a plurality of open-site batches associated with the plurality of remote radio unit sets. For example, taking n-9 as an example, the open-station configuration data may indicate that 9 remote radio units are divided into 3 open-station batches, and each open-station batch has 3 remote radio units. For example, one example of open configuration data is: set startupBatch 1RRU 1RRU 2 RRU 3; set startupBatch 2 RRU4 RRU5 RRU 6; set startup batch 3RRU7 RRU8RRU9, where set startup batch indicates setting up the start-up batch, and the above configuration data sets up the 1 st start-up batch, which relates to RRU1, RRU2, and RRU3, the 2 nd start-up batch, which relates to RRU4, RRU5, and RRU6, and the 3 rd start-up batch, which relates to RRU7, RRU8, and RRU 9. The open configuration data may be saved as an xml file, a database file, or other format that may be parsed.
The remote rf unit 120 sends a ready message to the baseband unit 110 after it is ready. The ready message may be transmitted to the baseband unit 110 through a fronthaul link, for example, through a Common Public Radio Interface (CPRI) protocol or an enhanced Common Public Radio Interface (eCPRI) protocol.
The baseband unit 110 is configured to obtain open-site configuration data 130 for the plurality of remote rf units 120 in response to receiving a plurality of ready messages from the plurality of remote rf units 120 coupled to the baseband unit 110, the open-site configuration data 130 indicating a plurality of sets of remote rf units into which the plurality of remote rf units 120 are divided and a plurality of open-site batches associated with the plurality of sets of remote rf units, the open-site including calibration and standing wave detection; sending a start-up message to a first set of remote radio units in the plurality of sets of remote radio units, the first set of remote radio units being associated with a first open-up batch; and in response to receiving the set of completed outbound messages from the first set of remote radio units, sending a start outbound message to a second set of remote radio units from the plurality of sets of remote radio units, the second set of remote radio units associated with a second outbound batch, the second outbound batch located after the first outbound batch.
Therefore, the plurality of remote radio frequency units coupled with the baseband unit are divided into a plurality of open-station batches, and the next batch of open stations are started after the previous batch of open stations is completed, so that the instantaneous total power consumption of the open stations of the plurality of remote radio frequency units coupled with the baseband unit can be reduced.
Fig. 2 shows a flow diagram of a method 200 for open-station of a plurality of remote radio units according to an embodiment of the present disclosure. For example, the method 200 may be performed by the baseband unit 110 as shown in fig. 1. It should be understood that method 200 may also include additional blocks not shown and/or may omit blocks shown, as the scope of the present disclosure is not limited in this respect.
At block 202, the baseband unit 110 receives a plurality of ready messages from a plurality of remote radio units 120 coupled to the baseband unit 110.
In response to baseband unit 110 receiving a plurality of ready messages from a plurality of remote radio units 120 coupled to baseband unit 110 at block 202, baseband unit 110 obtains open-site configuration data 130 for the plurality of remote radio units 120, open-site configuration data 130 indicating a plurality of sets of remote radio units into which the plurality of remote radio units 120 are divided and a plurality of open-site batches associated with the plurality of sets of remote radio units, open-site including calibration and standing wave detection, at block 204.
It should be understood that the open lot is associated with a set of remote radio units in the sense that the set of remote radio units is open in the open lot. The association of the plurality of open lots with the plurality of remote radio frequency unit sets means that the plurality of remote radio frequency unit sets are respectively open in the plurality of open lots.
At block 206, the baseband unit 110 sends a start open message to a first set of remote radio units of the plurality of sets of remote radio units, the first set of remote radio units associated with a first open lot.
The first set of remote radio units is associated with the first open lot in the sense that the first set of remote radio units is open in the first open lot.
At block 208, the baseband unit 110 receives a set of complete open station messages from a first set of remote radio units.
In response to the baseband unit 110 receiving the set of complete outbound messages from the first set of remote radio units at block 208, the base station unit 110 sends a start outbound message to a second set of remote radio units of the plurality of sets of remote radio units at block 210, the second set of remote radio units being associated with a second outbound batch, the second outbound batch being subsequent to the first outbound batch.
The second set of remote radio units is associated with the second open lot in the sense that the second set of remote radio units is open in the second open lot.
The above process can be performed according to the sequence of a plurality of starting batches until the plurality of remote radio frequency unit sets of the plurality of starting batches are opened. For example, the baseband unit 110 may also send a start out message to a third set of remote radio units of the plurality of sets of remote radio units in response to receiving the set of complete out messages from the second set of remote radio units, the third set of remote radio units being associated with a third open batch, the third open batch being subsequent to the second open batch.
Therefore, the plurality of remote radio frequency units coupled with the baseband unit are divided into a plurality of open-station batches, and the next batch of open stations is started after the previous batch of open stations is completed, so that the instantaneous total power consumption of the open stations of the plurality of remote radio frequency units coupled with the baseband unit can be reduced, the conditions that the power supply load of the whole station is high and the power supply is easy to trip in an unstable area or an insufficient power supply area of a power grid due to the fact that all the remote radio frequency units carry out calibration and standing wave detection at the same time and the service cannot be provided due to the fact that the startup, calibration and power failure processes are repeated after the station trips possibly caused by the fact that the software and hardware consistency of the plurality of remote radio frequency units is high are avoided.
Fig. 3 shows a flow diagram of a process 300 for the opening of a station for a plurality of remote radio units in accordance with an embodiment of the present disclosure. It should be understood that method 300 may also include additional blocks not shown and/or may omit blocks shown, as the scope of the disclosure is not limited in this respect. It should be understood that although 3 batches of remote radio unit sets are shown in fig. 3, this is by way of example only, and there may be 2 batches of remote radio unit sets or more than 3 batches of remote radio unit sets, and the scope of the present disclosure is not limited in this respect.
As shown in fig. 3, the baseband unit and 3 batches of remote rf units set start power up at 301 and software load and run.
The remote radio unit sets of the respective batches then send ready messages to the baseband units at 302, 303, 304.
The baseband unit sends a start out message to the set of remote radio units for batch 1 at 305. The remote rf unit set of lot 1 is open-ended, i.e., calibrated and standing wave detected at 306. After the completion of the opening, the remote RF unit set of lot 1 sends a complete opening message to the baseband unit at 307.
The baseband unit sends a start out message to the set of remote radio units for batch 2 at 308. The remote rf unit set for lot 2 is open-ended, i.e., calibrated and standing wave detected at 309. After the out-of-station is completed, the remote RF unit set for batch 2 sends a complete out-of-station message to the baseband unit at 310.
The baseband unit sends a start out message to the set of remote radio units for batch 3 at 311. The remote rf unit set for lot 3 is open-ended at 312, i.e., calibrated and standing wave detected. After the completion of the opening, the remote RF unit set of batch 3 sends a complete opening message to the baseband unit at 313. At this point, the remote radio frequency unit sets of 3 batches complete the opening.
Fig. 4 shows a schematic diagram of a comparison 400 of power consumption of the prior art with that of an embodiment of the present disclosure. As shown in the left side of fig. 4, in the prior art, since the n remote rf units coupled to the baseband unit are simultaneously open-ended (i.e., calibration and standing wave detection), the power consumption of the whole station is relatively high. In contrast, as shown in the right side of fig. 4, according to the embodiment of the present disclosure, since the n remote rf units coupled to the baseband unit are divided into 3 batches for opening, the power consumption of the whole station is greatly reduced. It should be understood that the 3 batches are merely illustrative and that other batches, such as 2 batches, or more than 3 batches, may be used.
Fig. 5 shows a flow diagram of a method 500 for acquiring open-site configuration data for a plurality of remote radio units according to an embodiment of the present disclosure. For example, the method 500 may be performed by the baseband unit 110 as shown in fig. 1. It should be understood that method 500 may also include additional blocks not shown and/or may omit blocks shown, as the scope of the disclosure is not limited in this respect.
At block 502, the baseband unit 110 determines a total number of remote radio units coupled to the baseband unit 110 based on the plurality of ready messages.
At block 504, the baseband unit 110 obtains a preset open power consumption and a current station available power. The preset open power consumption is generated based on the historical open power consumption of the remote radio unit, for example. The current site available power is generated, for example, based on the available power balance of the site where the baseband unit 110 is located.
At block 506, the baseband unit 110 generates open-station configuration data based on the preset open-station power consumption, the current station available power, and the total amount.
Specifically, the baseband unit 110 may determine the maximum allowed number of remote radio units for each open-station batch based on the preset open-station power consumption and the current station available power. For example, if the preset open station power consumption is P1 and the current station available power is T, the maximum allowed number M1 of remote radio units for each open station batch is rounded down (T/P1).
The baseband unit 110 may then generate a plurality of open lots and a plurality of remote radio units sets based on the determined maximum allowed number and the total number of remote radio units coupled to the baseband unit 110. For example, if the total number of remote radio units coupled to the baseband unit 110 is N, S1 open-stop batches may be obtained, S1 is rounded up (N/M1), and the plurality of remote radio units 120 may be divided according to the maximum allowable number M1 and S1 open-stop batches, so as to obtain S1 remote radio unit sets, where the number of remote radio units in each remote radio unit set does not exceed M1.
Therefore, the station opening configuration data can be generated in real time according to the total number of the remote radio frequency units currently coupled with the base band unit, the preset station opening power consumption and the current station available power, and therefore the station opening configuration data can reflect the current situation of the base band unit in time.
Fig. 6 shows a flow diagram of a method 600 for open-station of multiple remote radio units according to an embodiment of the present disclosure. For example, the method 600 may be performed by the baseband unit 110 as shown in fig. 1. It should be understood that method 600 may also include additional blocks not shown and/or may omit blocks shown, as the scope of the disclosure is not limited in this respect.
At block 602, the baseband unit 110 receives a plurality of ready messages from a plurality of remote radio units 120 coupled to the baseband unit 110.
At block 604, the baseband unit 110 determines a total number of remote radio units coupled to the baseband unit 110 based on the plurality of ready messages.
At block 606, the baseband unit 110 obtains a preset open power consumption and a current station available power.
At block 608, the baseband unit 110 generates open-site configuration data 130 for the plurality of remote radio units 120 based on the preset open-site power consumption, the current site available power, and the total number, the open-site configuration data 130 indicating a plurality of sets of remote radio units into which the plurality of remote radio units 120 are divided and a plurality of open-site batches associated with the plurality of sets of remote radio units, the open-site including calibration and standing wave detection.
At block 610, the baseband unit 110 sends a start open message to a first set of remote radio units of the plurality of sets of remote radio units, the first set of remote radio units associated with a first open lot.
At block 612, the baseband unit 110 monitors the set of open power consumptions of the first set of remote radio frequency units and determines a maximum open power consumption of the set of open power consumptions. For example, the baseband unit 110 may monitor the power consumption of each remote rf unit in the first set of remote rf units in real time through the fronthaul link.
At block 614, the baseband unit 110 receives a set of complete open station messages from a first set of remote radio units.
In response to receiving the set of complete open station messages from the first set of remote radio frequency units at block 6104, the baseband unit 110 determines whether the maximum open station power consumption is greater than a preset open station power consumption at block 616.
If the baseband unit 110 determines at block 616 that the maximum open power consumption is less than or equal to the preset open power consumption, it sends a start open message to a second set of remote radio units associated with a second open batch in the open configuration data, the second open batch being subsequent to the first open batch (not shown).
If the baseband unit 110 determines that the maximum power consumption for open stations is greater than the preset power consumption for open stations at block 616, the open station configuration data 130 is updated based on the maximum power consumption for open stations, the current station available power, and the total number of remote radio units coupled to the baseband unit 110 at block 618.
Specifically, the baseband unit 110 may determine the maximum allowed number of remote radio units for each remaining open-stop batch, each remaining open-stop batch being located after the first open-stop batch, based on the maximum open-stop power consumption and the current station available power. For example, the maximum open-station power consumption is Pmax, the current station available power is T, and the maximum allowed number M2 of remote radio units for each remaining open-station batch is rounded down (T/Pmax).
The baseband unit 110 may then determine the number of remote radio units to be powered on based on the total number of remote radio units coupled to the baseband unit 110 and the number of remote radio units in the first set of remote radio units. For example, if the total number is N and the number of remote radio units in the first set of remote radio units is M1, the number of remote radio units to be opened is N-M1. It should be understood that this is the case where the first open lot is the first open lot, and in the case where the first open lot is not the first open lot, the number of remote radio units to be opened may be N — the number of remote radio units already opened.
The baseband unit 110 may then generate a plurality of remaining open-stop batches and a plurality of sets of remote radio units associated with the plurality of remaining open-stop batches based on the maximum allowed number of remote radio units and the number of remote radio units to be opened for each remaining open-stop batch. For example, S2 remaining open-stop batches may be obtained, where S2 is rounded up (N-M1/M2), and the remote radio units 120 to be opened in N-M1 may be divided according to the maximum allowable number M2 and S2 remaining open-stop batches, so as to obtain S2 remote radio unit sets, where the number of remote radio units in each remote radio unit set does not exceed M2.
At block 616, the baseband unit 110 sends a start out message to a second set of remote radio units associated with a second open lot in the updated open configuration data, the second open lot being subsequent to the first open lot.
Therefore, the plurality of remote radio frequency units coupled with the baseband unit are divided into a plurality of open-station batches, and the next batch of open stations are started after the previous batch of open stations is completed, so that the instantaneous total power consumption of the open stations of the plurality of remote radio frequency units coupled with the baseband unit can be reduced. In addition, the station opening power consumption set of the first remote radio frequency unit set is monitored in real time, and the station opening configuration data is updated under the condition that the maximum station opening power consumption in the station opening power consumption set is larger than the preset station opening power consumption, so that the condition that the instantaneous total station opening power consumption of the rest station opening batches exceeds the available power of the current station can be avoided, and tripping is avoided.
In some embodiments, the baseband unit 110 updates the preset power consumption based on the maximum power consumption if it is determined that the maximum power consumption is greater than the preset power consumption. For example, the preset open power consumption is updated to the maximum open power consumption. Therefore, the maximum station starting power consumption counted in the station starting process can be used for updating the preset station starting power consumption, and the subsequent station starting can be conveniently used.
In some embodiments, the baseband unit 110 may also obtain a plurality of maximum open station power consumptions associated with a plurality of sets of remote radio frequency units. It should be understood that the maximum open station power consumption associated with a set of remote radio units refers to the maximum open station power consumption in the set of open station power consumption of the set of remote radio units, which may also be referred to as an open station batch power consumption peak. For the case of multiple open lots, there are multiple open lot power consumption peaks, e.g., if there are 3 open lots, there are corresponding 3 open lot power consumption peaks.
The baseband unit 110 may determine a maximum first maximum open power consumption from the plurality of maximum open power consumptions. That is, the largest open-lot power consumption peak among the plurality of open-lot power consumption peaks is determined. For example, if there are 3 open lots and corresponding 3 open lot power consumption peaks, the largest open lot power consumption peak is determined from the 3 open lot power consumption peaks.
The baseband unit 110 may determine whether the first maximum open power consumption is less than a preset open power consumption. The baseband unit 110 updates the preset power consumption if it is determined that the first maximum power consumption is less than the preset power consumption. The updated preset power consumption for opening the station can be used for opening the station in the next batch. The baseband unit 110 does not update the preset open power consumption if it is determined that the first maximum open power consumption is greater than or equal to the preset open power consumption.
Therefore, the first maximum station-opening power consumption of a plurality of remote radio frequency units in a plurality of station-opening batches can be determined, and the preset station-opening power consumption is updated under the condition that the first maximum station-opening power consumption is smaller than the preset station-opening power consumption, so that the preset station-opening power consumption can feed back actual conditions more truly, and the next automatic batch station-opening can be divided more accurately.
In addition, the baseband unit 110 may also update the updated open station configuration data based on the updated preset open station power consumption, the current station available power, and the total number in response to determining that the plurality of remote radio units are completely open station. For example, the baseband unit 110 may determine that the plurality of remote rf units are out of service by determining that a plurality of out of service messages from the plurality of remote rf units 120 are received.
Specifically, the baseband unit 110 may determine the maximum allowed number of remote rf units for each open lot based on the updated preset open power consumption and the current station available power. For example, if the updated preset open station power consumption is P2 and the current station available power is T, the maximum allowed number M3 of remote radio units for each open station batch is rounded down (T/P2).
The baseband unit 110 may then generate a plurality of open lots and a plurality of remote radio units sets based on the determined maximum allowed number and the total number of remote radio units coupled to the baseband unit 110. For example, if the total number of remote radio units coupled to the baseband unit 110 is N, S3 open-stop batches may be obtained, S3 is rounded up (N/M3), and the plurality of remote radio units 120 may be divided according to the maximum allowable number M3 and S3 open-stop batches, so as to obtain S3 remote radio unit sets, where the number of remote radio units in each remote radio unit set does not exceed M3.
Therefore, after the multi-batch remote radio frequency unit set is opened, the preset opening power consumption updated by the maximum opening power consumption counted in the opening process is used for updating the opening configuration data again, so that the opening configuration data can be more accurately and actually opened, and the condition of tripping in the next opening process is avoided.
