[0038] See Figure 2 , preferably, the power splitter is a one - to - three power splitter; when the first switch joint 101 is switched to be connected to the first output terminal Y1 of the power splitter, the second switch joint 102 is switched to be connected to the second output terminal Y2 of the power splitter, the third switch joint 103 is switched to be connected to the third output terminal Y3 of the power splitter, and the fourth switch joint B3 is switched to be connected to the input terminal Y0 of the power splitter, at this time, the input of the power splitter is the second antenna connector 112, and the three outputs are respectively the first antenna 10, the second antenna 20, and the third antenna 30. That is, at this time, the three groups of antennas are all connected to the RRU2 of the sector corresponding to the second antenna connector 112 through the power splitter. At this time, the first antenna 10, the second antenna 20, and the third antenna 30 work together in the omnidirectional antenna working mode, and the RRUs 1 and 3 of the three sectors of the base station are in the off state, and the RRU2 is in the working state.

[0039] In this embodiment, by setting the first time period and the second time period, and using two different time periods as the working time periods for switching the antenna working mode of the green energy - saving antenna, when switching from one time period to another, the green energy - saving antenna is controlled to enter the corresponding antenna working mode; specifically:

[0040] In the first time period, the first switch joint 101, the second switch joint 102 and the third switch joint 103 are controlled to be switched and connected to the corresponding connectors respectively (that is, the first switch joint 101 is connected to the first connector, the second switch joint 102 is connected to the second connector, and the third switch joint 103 is connected to the third connector), and the fourth switch joint is controlled to be switched and connected to the corresponding switch path, so that the green energy-saving antenna is in a directional antenna working mode; this embodiment only includes a fourth switch joint B3 arranged on the feeder line of the second antenna connector 112, that is, at this time, the fourth switch joint B3 is switched to be connected to the second switch path, so that the second antenna connector 112 is connected to the second switch path; and the first antenna connector 111 is directly connected to the corresponding first switch path. , the third antenna connector 113 is directly connected to the corresponding third switch path, then at this time, the first antenna 10 is electrically connected to the RRU of the first sector of the base station antenna through the first antenna connector 111, the second antenna 20 is electrically connected to the RRU of the second sector of the base station antenna through the second antenna connector 112, and the third antenna 30 is electrically connected to the RRU of the third sector of the base station antenna through the third antenna connector 113. At this time, RRU1, RRU2 and RRU3 corresponding to the three sectors of the base station all remain in working state, that is, the first antenna 10 works under the action of the first sector RRU1, the second antenna 20 works under the action of the second sector RRU2, and the third antenna 30 works under the action of the third sector RRU3, that is, the green energy-saving antenna is in the directional antenna working mode at this time.

[0041] In the second period, the first switch joint 101, the second switch joint 102 and the third switch joint 103 are respectively switched to the corresponding output end of the power divider (that is, the first switch joint 101 is switched to the first output end of the power divider, the second switch joint 102 is switched to the second output end of the power divider, and the third switch joint 103 is switched to the third output end of the power divider), and the fourth switch joint is controlled to switch to the input end of the power divider, so that the green energy-saving antenna is in the omnidirectional antenna working mode. Figure 2 As shown, this embodiment specifically switches the fourth switch joint B3 to be connected to the input end of the power divider. At this time, the first antenna 10 is disconnected from the RRU1 corresponding to the first sector, and the third antenna 30 is disconnected from the RRU3 corresponding to the third sector. Only the RRU2 corresponding to the second sector is connected to the input end of the power divider, and is connected to the first antenna 10, the second antenna 20 and the third antenna 30 through the three output ends of the power divider, that is, the first antenna 10, the second antenna 20 and the third antenna 30 work together in the omnidirectional antenna working mode; at this time, the RRU1 corresponding to the first sector of the base station is in a closed state, the RRU3 corresponding to the third sector is in a closed state, and the RRU2 corresponding to the second sector is in a working state.

[0042] This embodiment can make the corresponding antenna in the green energy-saving antenna work by changing the switch state of each switch joint, so as to be in the corresponding antenna working mode. Preferably, the first switch path of this embodiment is composed of a fixed switch node A1 and a feeder, the second switch path is composed of a fixed switch node B1, a fixed switch node B2 and a feeder, and the third switch path is composed of a fixed switch node C1 and a feeder; the first switch joint 101 can be switched to be electrically connected to the fixed switch node A1, the second switch joint 102 can be switched to be electrically connected to the fixed switch node B1, and the third switch joint 103 can be switched to be electrically connected to the fixed switch node C1.

[0043] In this embodiment, a first time period and a second time period are set, and two different time periods are used as working periods for switching the antenna working mode of the green energy-saving antenna. When entering from one time period to another time period, the green energy-saving antenna is controlled to enter the corresponding antenna working mode; specifically, when entering from the first time period to the second time period at this time, the green energy-saving antenna is switched from the directional antenna working mode to the omnidirectional antenna working mode; when entering from the second time period to the first time period at this time, the green energy-saving antenna is switched from the omnidirectional antenna working mode to the directional antenna working mode; the specific mode switching is achieved by switching the switch state of each switch joint as mentioned above, which will not be repeated here.

[0044] The first time period and the second time period are specifically the relative busy and idle time periods in a day. The division of "idle" and "busy" can be determined based on the local geographical conditions and the user's communication needs; for example, in an optional application mode, 8 am to 12 pm is set as the first time period, and 0 am to 8 am is set as the second time period, so the sector antenna corresponding to the base station is replaced by the green energy-saving antenna, and the working state is directional antenna working mode in "busy time" and omnidirectional antenna working mode in "idle time"; that is, in the "busy time" with large cell traffic, the green energy-saving antenna replaces the sector antenna working mode with directional antenna coverage, and the RRUs of the three sectors work simultaneously; in the "idle time" from midnight to early morning, the working mode of the green energy-saving antenna based on beam switching is omnidirectional antenna working mode, and the total energy consumption of the base station is 3*16*P+8*P=56P, where P is the unit of measurement of antenna energy consumption; and if the original base station antenna is in 24-hour 3-sector directional antenna working mode, the total energy consumption of the base station is 3*24*P=72P. Therefore, when the green energy-saving antenna based on beam switching provided in this embodiment replaces the existing base station antenna or a new base station adopts the green energy-saving antenna arrangement provided in this embodiment, the base station switches between the two working states of "busy time" and "idle time", and its energy consumption can be reduced by 22.2%, that is, this embodiment can effectively reduce the antenna energy consumption.

[0045] In one application scenario, the green energy-saving antenna based on beam switching provided in this embodiment can switch the directional antenna working mode to the omnidirectional coverage mode through the beam when a sector RRU failure occurs in the base station, so that the green energy-saving antenna is connected to the non-faulty RRU. In this way, it can be used as an emergency plan to avoid the crisis of communication interruption in the sector in a very short time, and restore normal cell communication after the fault is eliminated. For example, when a communication failure occurs in the first sector of the base station, it is necessary to troubleshoot, repair or take other new emergency measures to restore the coverage and communication quality of the cell as soon as possible, and the cell faces the problem of being unable to communicate during this fault resolution period; in this regard, the green energy-saving antenna can be switched from the directional antenna working mode to the omnidirectional antenna working mode, that is, the operation of the first sector RRU is turned off. At this time, the antenna is in the omnidirectional antenna working mode, and this time can be used for fault detection and maintenance. After the fault is eliminated, the three-sector directional antenna working mode of the cell can be restored, so that there will be no long-term cell communication interruption.

[0055] Embodiment 3

[0056] Figure 7 Show the green energy-saving antenna based on beam switching provided by the third embodiment of the present invention. This embodiment is an extended example based on the first embodiment or the second embodiment. The following will be described based on the second embodiment. In this embodiment, it includes the same first antenna, second antenna, third antenna, and power splitter as the second embodiment. The difference is that this embodiment specifically includes three fourth switch joints, which are respectively arranged on the feed lines at one end of the first antenna connector 111, the second antenna connector 112, and the third antenna connector 113. The three fourth switch joints can be switchably connected to the input end of the power splitter or the corresponding switch paths; specifically, the fourth switch joint 211 corresponding to the first antenna connector 111 can be switchably connected to the input end Y0 of the power splitter or the first switch path where the first connector is located; the fourth switch joint 212 corresponding to the second antenna connector 112 can be switchably connected to the input end Y0 of the power splitter or the second switch path where the second connector is located; the fourth switch joint 213 corresponding to the third antenna connector 113 can be switchably connected to the input end Y0 of the power splitter or the third switch path where the third connector is located.

[0057] Preferably, the first switch path is composed of a first fixed switch node A1, a second fixed switch node A2, and a feed line connecting the first fixed switch node A1 and the second fixed switch node A2; the first switch joint 101 can be switchably connected to the first fixed switch node A1 or the first output end Y1 of the power splitter, and the fourth switch joint 211 on the first antenna connector 111 can be switchably connected to the input end Y0 of the power splitter or the second fixed switch node A2. The second switch path is composed of a third fixed switch node B1, a fourth fixed switch node B2, and a feed line connecting the third fixed switch node B1 and the fourth fixed switch node B2; the second switch joint 102 can be switchably connected to the third fixed switch node B1 or the second output end Y2 of the power splitter, and the fourth switch joint 212 on the second antenna connector 112 can be switchably connected to the input end Y0 of the power splitter or the fourth fixed switch node B2. The third switch path is composed of a fifth fixed switch node C1, a sixth fixed switch node C2, and a feed line connecting the fifth fixed switch node C1 and the sixth fixed switch node C2; the third switch joint 103 can be switchably connected to the fifth fixed switch node C1 or the third output end Y3 of the power splitter, and the fourth switch joint 213 on the third antenna connector 113 can be switchably connected to the input end Y0 of the power splitter or the sixth fixed switch node C2.

[0058] This embodiment ensures that even if any sector RRU fails, as long as the RRUs of the three sectors do not fail at the same time, the base station can safely switch to the omnidirectional antenna working mode; for example, if the RRU of the first sector fails, the switch joint 212 or the switch joint 213 can be switched to connect to Y0, and the first switch joint 101, the second switch joint 102 and the third switch joint 103 are correspondingly switched to connect to the first output terminal Y1, the second output terminal Y2 and the third output terminal Y3 of the power divider, so that the antenna switches to the omnidirectional antenna working mode as an emergency plan without causing cell communication interruption.

[0059] In summary, the green energy-saving antenna based on beam switching described in the present invention can realize the conversion of the antenna between the directional antenna working mode and the omnidirectional antenna working mode by switching the internal switch matrix of the antenna; after replacing the antenna of a sector of the existing base station with the green energy-saving antenna based on beam switching, switching the different working modes of the green energy-saving antenna during "busy time" and "idle time" can effectively reduce the energy consumption of the base station; and when a communication failure occurs in a sector of the base station (not the replaced sector), the green energy-saving antenna is used to switch the directional coverage mode of the base station to the omnidirectional coverage mode, which can solve the crisis of communication interruption of the sector in a very short time.

[0060] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
