First kind of embodiment is that the base station with three sectors is the example explanation.As shown in Figure 4, this base station comprises three sender TX1, TX2, TX3 and three transmitting antenna ANT1, ANT2, ANT3, the application of corresponding three sectors.Between these three senders and three transmitting antennas, the crosspoint that transmits is installed, the crosspoint that transmits comprises three single-pole double-throw switch (SPDT)s, a SP3T switch, a power splitter and one 5 cutter 3 throw switches, each sender is drawn two connecting lines by a single-pole double-throw switch (SPDT), 3 connecting lines of drawing from 3 single-pole double-throw switch (SPDT)s are connected with an end of 5 cuttves, 3 throw switches respectively, other 3 connecting lines of drawing from 3 single-pole double-throw switch (SPDT)s and an end of SP3T switch are connected respectively, the other end of SP3T switch is connected with an end of power splitter, the other end of power splitter is connected with an end of 5 cuttves, 3 throw switches simultaneously, and the other end of 5 cuttves, 3 throw switches is connected with 3 antennas.
At three senders all is under the normal situation, selector switch closure between TX1 and 5 cuttves, 3 throw switches, the signal that TX1 sends is launched by ANT1, selector switch closure between TX2 and 5 cuttves, 3 throw switches, the signal that TX2 sends is launched by ANT2, selector switch closure between TX3 and 5 cuttves, 3 throw switches, the signal that TX3 sends is launched by ANT3.This time TX1, TX2, TX3 respectively and the selector switch between the power splitter disconnect.
Under the situation that a sender breaks down, such as TX1 breaks down, and then ANT1 does not transmit, and the handshaking functional unit will distribute the signal of TX2 or TX3.For example the signal with TX2 distributes, switch between this time TX2 and 5 cuttves, 3 throw switches disconnects, and selector switch between the power splitter and power splitter switch closure, the signal of TX2 arrives power splitter through switch, be divided into two-way, in 5 cuttves, 3 throw switches, this two paths of signals and TX3 are directly inputted to the signal allocation that 5 cuttves 3 throw and give ANT1, ANT2 and ANT3.Consequently: TX3 does not change to the signal of ANT3, and the signal of TX2 is divided into two-way and gives ANT1 and ANT2 respectively, thereby has realized the mutual backup between sender.As shown in Figure 5, after TX1 broke down, the signal allocation of TX2 was given ANT1 and ANT2 emission, and the gross power resource of first sector and second sector is reduced to 10W respectively.
Aforesaid way not only is suitable for the base station of three sectors, equally also is suitable for above base station, three sectors.
Second kind of embodiment also is that the base station with three sectors is the example explanation.As shown in Figure 6, this base station comprises three sender TX1, TX2, TX3 and three transmitting antenna ANT1, ANT2, ANT3, the application of corresponding three sectors.Each sender divides by merit and leads directly to selector and two antennas are corresponding, one of the two-way output of sender TX1 is respective antenna ANT1, another output is respective antenna ANT2, one of the two-way output of sender TX2 is respective antenna ANT2, another output is respective antenna ANT3, one of the two-way output of sender TX3 is respective antenna ANT3, and another output is respective antenna ANT1, and each antenna is corresponding with two different senders.Divide and lead directly to 3 connecting lines that selector draws and be connected from 3 merits respectively with a pin of an end of 3 single-pole double-throw switch (SPDT)s, divide with another pin of an end that leads directly to other 3 connecting lines that selector draws and 3 single-pole double-throw switch (SPDT)s from 3 merits respectively to be connected, the other end of single-pole double-throw switch (SPDT) is connected with 3 antennas.Merit is divided and led directly to selector two kinds of operating states, and the one, be two paths of signals with signal halves, another is that signal is through to wherein one tunnel output, another road no-output.
The merit of each sender correspondence is divided and is led directly to selector and have only one the tunnel straight-through when three sender TX1, TX2, TX3 are normal, the signal that sends of TX1 is launched by ANT1 like this, the signal that TX2 sends is launched by ANT2, and the signal that TX3 sends is launched by ANT3.
Under the situation that a sender breaks down, such as TX1 breaks down, and then ANT1 does not transmit, and the handshaking functional unit will distribute the signal of TX2 or TX3.For example the signal with TX2 distributes, this time the TX2 correspondence merit divide with leading directly to selector and be operated in merit and divide state, the TX2 signal halves becomes two-way, at the single-pole double-throw switch (SPDT) place that is connected with antenna, this two paths of signals is given ANT1 and ANT2 respectively.Consequently: TX3 does not change to the signal of ANT3, and the signal of TX2 is divided into two-way and gives ANT1 and ANT2 respectively, thereby has realized the mutual backup between sender.As shown in Figure 4, after TX1 broke down, the signal allocation of TX2 was given ANT1 and ANT2 emission, and the power of first sector and second sector is reduced to 10W respectively.
This mode not only is suitable for the base station of three sectors, equally also is suitable for above base station, three sectors.
After sender was finished backup, the base station reported base station controller with the state variation that this base station takes place, and base station controller is readjusted the radio-resource-configuration of each sub-district, as changing pilot channel power, reached the performance of optimal performance under the existing resource situation.
When sender was supported two sectors, because the original signal of a sector of supporting was distributed on two sectors, the power of each sector only had original half, promptly low 3dB.Can do corresponding the adjustment to the management of Radio Resource by base station controller, original each channel transmitting power is doubled, equivalence is the same before signal power and the fault to each fan antenna mouth, makes that the covering of base station is constant substantially, and only capacity reduces.As shown in Figure 4, in original each sector the 20W gross power is arranged, for example being provided with than gross power of former pilot channel hanged down 10dB, and the absolute power of pilot channel is 2W; Owing to wait and give two sectors, the power of each sector reduces by half, and the pilot power that backs up a back sector is reduced to 1W, after base station controller is readjusted according to the variation of base station state, transmit signal power doubles, and the pilot power on each sector recovers to become 2W again.The Power Processing of other Traffic Channels mode therewith is the same, obtains and original the same absolute power.
Technical solution of the present invention, can be under the acceptable decreased performance situation of system, implemented the mutual backup between the sender at low cost, improved the reliability of base station greatly, on backup method, the cost of increase has had very big decline than conventional method, and the signal exchange unit that increases newly is simple in structure, the reliability height of used switch makes the reliability of system itself that large increase arranged.
