detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to Figure 2, an embodiment of a base station radio frequency switching device 10 of the present invention is presented. The device 10 is configured to be connected to the radio frequency output portion 201 of the base station 20. The radio frequency output portion 201 includes at least two cell output channels to which the antenna 30 is connected. The device 10 includes: at least two switch modules 101 and at least one power sub-module 102. ;

The switch module 101 is disposed on each cell output channel; the power split module 102 is disposed on a partial cell output channel, and is connected to the switch module 101 of the cell output channel;

When the network is idle, the base station 20 is switched to the power saving state by the switch module 101 and the power dividing module 102;

When the network is busy, the base station 20 is restored to the normal state by the switch module 101.

The base station radio frequency switching device 10 of the present embodiment can be connected with the control center 11, the base station controller 40, and the OMC-R server 50, and controls the adjustment of the power output of the base station 20 (via the antenna 30) according to a predetermined policy, so that the base station 20 is energy-saving. Switching between the state and the normal state achieves the purpose of saving the energy consumption of the base station 20. The adjustment of the power output may include turning on, off, and lifting of the power output. The above normal state refers to the multi-sector coverage state (directed station coverage) in the prior art, and mainly refers to the three-sector coverage state. The foregoing energy saving state may be that some of the cell output channels in the base station 20 are output power of other cells in the base station 20. (Refer to Figure 3)

The control center 11 can switch the radio frequency power output of the base station 20 according to a predetermined policy or according to the traffic condition, and convert the directional station coverage into an omnidirectional station coverage. The established policy may be a timed handover, that is, the base station 20 may be switched to a power saving state within a set period of time (a period of low traffic volume). According to the traffic situation, the traffic volume of the cell carrier within the set time may be counted, and the number of channels required in the case of the traffic volume may be calculated, thereby selecting an appropriate sector for coverage. For example, in the three-sector coverage state, the threshold of the traffic volume in the energy-saving state is set. When the current traffic volume is less than the threshold, the base station 20 is switched to the energy-saving state by the switch module 101 and the power split module 102, and the Or the power output of the two base stations 20, using the remaining cell output power, does not affect the service processing.

The switch module 101 can be a single-point two-touch switch, or can be a single-point multi-touch switch that is also selective; the power split module 102 can be a three-power splitter, or a multi-power splitter that also has a power split function. Wait. When the base station 20 is in a three-sector coverage state (that is, includes three cells), at least one single-point two-touch switch is disposed on the cell output channel of each cell; a three-power splitter can be set in one of the cell output channels. The single-point two-touch switch is connected, and at least two single-point two-touch switches are arranged on the output channel of the cell, and one is arranged before and after the three-power splitter; when the energy-saving state needs to be entered, the single-point two-touch switch is selected and utilized. The three-power splitter outputs power for the cell, and the other two cells are connected to the three-power splitter through a single-point two-touch switch, and receive the output power and transmit it to the antenna 30 corresponding to the respective cell; thus, through the four A single-point two-touch switch and a three-power splitter can provide power output for the other two cells by using a cell connected with a three-power splitter, so that the base station 20 enters a power-saving state to save energy. And when it is required to enter the normal state, the single-point two-touch switch on the cell output channel is selected to be disconnected from the three-power splitter, and the original line is used for power output.

The base station radio frequency switching device 10 can flexibly switch the base station 20 between the energy-saving state and the normal state according to actual operation conditions, thereby reducing the energy consumption of the base station 20, and being convenient and practical.

Referring to Figure 4, another embodiment of a base station radio frequency switching device 10 of the present invention is presented. The device 10 may further include: a first power detecting module 103, configured on the cell output channel of the switch module 101 and the base station 20, and detecting an output power of the cell output channel. In this way, the output power of each cell when the base station 20 is in a normal state can be detected. When the base station 20 is in a normal state, the first power detecting module 103 detects the cell output power, and reports the power to the control center 11 for analysis. When the control center 11 analyzes that the network of the base station 20 is idle, the switch module can pass the foregoing switch module. 101 (single-point two-touch switch) and power splitting module 102 (three-power splitter) adjust base station 20 to a power-saving state; if it is analyzed that the base station 20 network is busy, then base station 20 is kept in a normal state.

The busy or idle determination of the network of the base station 20 may be that, when the base station 20 is in the power-saving state, if the power required to provide the closed cell is not less than 20 dBm, the network of the base station 20 may be considered to be idle; Then, the base station 20 network can be considered to be busy.

The device 10 may further include: a second power detecting module 104, disposed on the cell output channel of the switch module 101 and the antenna 30, and detecting an output power of the cell output channel. When the base station 20 is in a power saving state, the second power detecting module 104 can detect the output power of each cell. When the second power detecting module 104 detects that the power of the closed cell needs to be greater than or equal to 20 dBm for each closed cell, the reporting control center 11 adjusts the base station 20 from the energy saving state to the normal state, without affecting the base station 20 Normal business processing.

The above-mentioned switch module 101 (single-point two-touch switch) and power split module 102 (three-power splitter) can be set according to specific conditions. For example, two single-point two-touch switches can be set on each cell output channel, which makes the device 10 run more stably. And setting a three-power splitter on one of the output channels of each of the three cells, and providing power output to the other two cells through one cell in the energy-saving state; or setting two, using two cells to provide three The power output of the cells; when the number of cells increases, the number of the three power dividers can also increase. (Refer to Figure 4)

The base station radio frequency switching device 10 can also automatically switch the base station 20 to a normal state in the event of an emergency. For example, according to the actual situation of the base station 20, the state of the base station 20 needs to be switched to the normal state, and when the accident cannot be successfully switched, the automatic bypass function can be activated, and the switch module 101 (single-point two-touch switch) and the power split module 102 are disconnected. (Triple power splitter), so that the base station 20 is in a normal state, and the emergency situation is released.

Referring to FIG. 5, the above device 10 may further include: a query module 105 that provides status and parameter queries and accepts local or remote monitoring. The query module 105 can perform status and parameter monitoring, such as power on/off status, power failure warning, fault warning, temperature warning, and operating parameters of a single-point two-touch switch, a three-way splitter, and the like. The query module 105 can report the monitored status and parameters to the control center 11.

The device 10 also reserves a remote monitoring software update download function. When the software is updated, the device 10 causes the base station 20 to be in a normal state (directed station coverage) through the automatic bypass function. The automatic bypass function directly converts the base station 20 from the power saving state to the normal state without considering the current traffic volume.

The device 10 described above may further include: a detecting module 106 that detects the battery and sends the fault information to the control center 11 when the battery stops supplying power. The automatic reporting of the above fault information can enable the control center 11 to promptly remind the administrator of the immediate maintenance.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structure or equivalent process transformations made by the description of the invention and the drawings are directly or indirectly applied to other related The technical field is equally included in the scope of patent protection of the present invention.
