Examples 1,
Fig. 5 is a flowchart illustrating a base station control method according to an embodiment of the present application, which is applied to the communication system shown in fig. 1. The base station control method specifically comprises the following steps:
s501, the first base station receives a random access request message from target User Equipment (UE).
Specifically, the transceiver module 11 of the first base station 10 receives the random access request message from the target UE 30. Among them, the target UE30 may be a UE30 accessing the first base station 10.
S502, the first base station determines that the UE is the first UE or the second UE according to the random access request message.
Specifically, the processing module 12 of the first base station 10 determines that the target UE30 is the first UE or the second UE according to the random access request message.
The distance between the first UE and the first base station is greater than the distance between the second UE and the first base station, and the random access request message comprises the sending time and the signal sending power of the random access request message.
The processing module 12 of the first base station 10 determines the transmission time of the random access request message according to the sending time and the receiving time of the random access request message; determining the transmission loss of the random access request message according to the signal sending power and the signal receiving power of the random access request message; if the transmission time is greater than the first threshold or the transmission loss is greater than the second threshold, the target UE30 is determined to be the first UE, otherwise, the target UE30 is determined to be the second UE.
The first base station distinguishes the target UE30 into a first UE and a second UE according to the length of the message transmission time or the transmission loss, so as to determine whether there is the number of target UEs 30 that may be affected by the change of the number of the transceiving channels within the coverage area of the first base station.
S503, the first base station acquires the load of the first base station and the load of the second base station in unit time.
Specifically, the transceiver module 11 of the first base station 10 obtains the load of the first base station 10 and the load of the second base station 20 in a unit time.
The second base station 20 is a base station having the same coverage area as the first base station 10.
The load of the base station is used to indicate the traffic load of the first base station 10 or the second base station 20 per unit time. The load Tp may include parameters such as Radio Resource Control (RRC) connection number Lc, Physical Resource Block (PRB) utilization Lu, and the like based on the base station.
For example, the load of the first base station 10 or the second base station 20 may be calculated by the following formula:
Figure BDA0002114256950000071
wherein, a and b are weight coefficients, and satisfy a + b as 1, LcmaxMaximum number of RRC connections, Lu, supported by the base stationmaxThe maximum utilization rate of PRB is 100%.
Alternatively, the first base station 10 may determine the second base station 20 by:
in one way, the transceiver module 11 of the first base station 10 obtains a first RSRP and a second RSRP from the target UE30, where the first RSRP is the RSRP of the first base station 10 measured by the target UE30, and the second RSRP is the RSRP of the neighboring base station measured by the target UE 30; when the difference between the first RSRP and the second RSRP is smaller than the twelfth threshold, the processing module 12 of the first base station 10 determines that the target UE30 is a third UE; when the ratio of the number of the third UEs to the number of all UEs is greater than the thirteenth threshold, the processing module 12 of the first base station 10 determines that the neighboring base station is the second base station 20.
Alternatively, the information of the second base station 20 (such as the identifier of the second base station 20) may be stored in the first base station 10 in advance, and the processing module 12 of the first base station 10 determines the second base station 20 according to the stored information of the second base station 20.
S504, the first base station switches the transceiving mode of the first base station according to whether the load of the first base station meets the preset condition, the duration that the load of the first base station meets the preset condition, the load of the second base station, the number of the first UE and the number of the second UE.
Specifically, the processing module 12 of the first base station 10 switches the transceiving mode of the first base station 10 according to whether the load of the first base station satisfies the preset condition, the duration that the load of the first base station 10 satisfies the preset condition, the load of the second base station 20, the number of the first UEs, and the number of the second UEs.
When the load of the first base station 10 is smaller than the third threshold, the duration that the load of the first base station 10 is smaller than the third threshold is larger than the fourth threshold, the number of the first UEs is smaller than the fifth threshold, and the number of the second UEs is larger than the sixth threshold, the first base station 10 switches to the first transceiving mode.
Or, when the load of the first base station 10 is less than the third threshold, the duration that the load of the first base station 10 is less than the third threshold is greater than the fourth threshold, the number of the first UEs is less than the fifth threshold, and the number of the second UEs is less than the sixth threshold, the first base station 10 switches to the second transceiving mode, where the number of the transmission channels of the second transceiving mode is less than the number of the transmission channels of the first transceiving mode.
Or, when the load of the first base station 10 is smaller than the seventh threshold and the duration that the load of the first base station 10 is smaller than the seventh threshold is greater than the eighth threshold, the first base station 10 switches to the third transceiving mode, where the seventh threshold is smaller than the third threshold, the eighth threshold is greater than the fourth threshold, and the third transceiving mode is to close all transmitting channels and open all receiving channels.
Or, when the load of the first base station 10 is greater than the third threshold, the duration that the load of the first base station 10 is greater than the third threshold is greater than the fourth threshold, or the number of the first UEs is greater than the fifth threshold, the first base station 10 switches to a fourth transceiving mode, where the fourth transceiving mode is to open all the transmitting channels and the receiving channels.
Or, when the load of the first base station 10 is smaller than the ninth threshold, the duration that the load of the first base station 10 is smaller than the ninth threshold is larger than the tenth threshold, and the load of the second base station 20 is smaller than the eleventh threshold, the first base station 10 switches to the fifth transceiving mode, where the ninth threshold is smaller than the seventh threshold, the tenth threshold is larger than the eighth threshold, and the fifth transceiving mode is to close all the transmitting channels and the receiving channels.
In a practical network, the distribution of UEs is random, and there must be a certain number of target UEs 30 in the same coverage area of the first base station 10 and the second base station 20, and these target UEs 30 will select the first base station 10 or the second base station 20 when accessing the network. When the first base station 10 closes the number of all transceiving channels, the target UE30 in the coverage area may select to access the second base station 20, and at this time, the load of the second base station 20 may increase, and in order to avoid that the load of the second base station 20 is too high and the access performance of the target UE30 is degraded, it is also required to determine whether the load of the second base station 20 is at a lower level when the first base station 10 closes all transmitting channels.
The first base station 10 may switch between the first to fifth transceiving modes according to actual situations, thereby ensuring the access performance of the target UE 30.
The first transceiving mode may be to turn off C1 transmitting channels, turn on C0-C1 transmitting channels and C0 receiving channels. The second transceiving mode may be to turn off C2 transmitting channels, turn on C0-C2 transmitting channels and C0 receiving channels. Wherein C1< C2< C0, and C0 is the total number of receive or transmit channels supported by the first base station.
For example, when the first base station 10 switches to the first transceiving mode, when C0 is 64, C1 is 32, and C2 is 48, the first base station 10 has 32 transmit channels and 64 receive channels in an operating state; when the first base station 10 switches to the second transceiving mode, the first base station 10 has 16 transmit channels and 64 receive channels in an operating state.
In the base station control method provided by the embodiment of the application, the first base station receives a random access request message from the target UE, the target UE is divided into the first UE and the second UE according to the random access request message, and the transceiving mode of the first base station is switched according to whether the load of the first base station meets a preset condition, the duration of the preset condition that the load of the first base station meets the preset condition, the load of the second base station having the same coverage area, the number of the first UEs and the number of the second UEs. Different transceiving modes are determined according to the load of the base station, the distribution of the UE and the load and the access performance of the adjacent base stations, the number of transceiving channels of the first base station is adjusted through the different transceiving modes, and the most transceiving channels are closed as far as possible on the premise of ensuring the access performance of the UE, so that the power consumption of the base station is reduced.
Optionally, as shown in fig. 6, after S504, S505-S510 are further included, configured to instruct the first base station 10 to switch to the fourth transceiving mode according to the load of the second base station 20 when the first base station 10 switches to the fifth transceiving mode:
s505, the first base station sends a first message to the second base station.
Specifically, the transceiver module 11 of the first base station 10 sends a first message to the second base station 20.
Wherein the first message is used to instruct the first base station 10 to switch to the fifth transceiving mode.
Optionally, the first message may include an identifier of the first base station 10, an identifier of the second base station 20, and an instruction for the first base station 10 to switch to the fifth transceiving mode, and the second base station 20 may identify the first base station 10 according to the identifier of the first base station 10.
S506, the second base station receives the first message from the first base station.
Specifically, the transceiver module 21 of the second base station 20 receives the first message from the first base station 10.
The first message is used to instruct the first base station 10 to switch to a fifth transceiving mode, where the fifth transceiving mode is to close all the transmitting channels and the receiving channels.
The second base station 20 receives the first message, which indicates that the first base station 10 has switched or is about to switch the fifth transceiving mode, at which point the first base station 10 will close all transceiving channels, and the target UE30 in the same coverage area of the first base station 10 and the second base station 20 will be served by the second base station 20.
And S507, the second base station acquires the load and the access success rate of the second base station in unit time.
Specifically, the processing module 22 of the second base station 20 obtains the load and the access success rate of the second base station 20 in a unit time.
The access success rate is a ratio of the number of UEs 30 successfully accessing the second base station 20 to the number of all UEs 30 initiating the access request and the hand-in request to the second base station.
