Based on above-mentioned BBU, the present invention also provides a kind of base stations, as shown in figure 4, the base station includes: BBU 21 and RRU 22；
Wherein, RRU 22 can be multiple, including boundary RRU 22 and non-boundary RRU 22,
BBU 21, for, without business, opening boundary RRU 22 in the coverage area of the determining all RRU 22 connected, closing
Close non-boundary RRU 22；It determines that boundary RRU 22 has service access, opens non-boundary RRU 22；
RRU 22 for transmitting the information of service access to BBU 21, and is opened or is closed according to the control of BBU 21
It closes.
In a specific embodiment, the BBU 21, specifically for all RRU 22 according to connection without uplink
Signal is sent, and is determined without business in the coverage area of all RRU 22 of connection, is notified boundary RRU's 22 by optical interface
Radio frequency link is opened and the radio frequency link of non-boundary RRU 22 is closed, wherein be can be and is only notified what no specified services needed
The radio frequency link of non-boundary RRU is closed, and the radio frequency link for the non-boundary RRU for having specified services to need is opened.
In a specific embodiment, the BBU 21, specifically for receiving the uplink signal of the transmission of boundary RRU 22,
It determines that boundary RRU 22 has service access, notifies the radio frequency link of non-boundary RRU 22 to open by optical interface.
In a specific embodiment, the BBU 21, specifically for notifying each non-boundary RRU simultaneously by optical interface
22 radio frequency link is opened, alternatively, according to the how far of non-boundary RRU 22 and the boundary RRU 22 for having service access, according to
Sequence from the near to the distant notifies the radio frequency link of non-boundary RRU 22 to open one by one by optical interface.
In a specific embodiment, the BBU 21 is also used to after opening non-boundary RRU 22, continues judgement connection
All RRU 22 coverage area in whether there are also business, without industry in the coverage area of all RRU 22 for determining connection
When business, boundary RRU 22 is opened, non-boundary RRU 22 is closed.
In addition, the BBU 21, is also used to according to the preconfigured time for having service access in boundary RRU 22, really
When being scheduled on more than specified time time, the uplink signal that the boundary RRU 22 is sent is not received yet, then described in judgement
22 failure of RRU or link down open the radio frequency link of nearest non-boundary RRU 22 adjacent with the boundary RRU 22.
Below by a concrete scene, the present invention is described in detail.
In scenes such as high-speed rail, highways, base station generally uses chain mode networking, as shown in figure 5, each baseband processing unit
(BBU) multiple Remote Radio Unit (RRU) are connected, the multiple RRU covers different sections of highway, and merges as a cell
(cell).Such as shown in Fig. 5,2 RRU are hung on every pole, are covered each by positive and negative both direction, 6 RRU are connected to one
BBU, merging becomes a cell.
For each cell, BBU keeps head and the tail two when determining does not have business in the coverage area of all RRU of connection
The radio frequency link of a RRU is normally-open, and the radio frequency link of intermediate RRU is according to service conditions unlatching/closing.Such as: 1 and No. 6 RRU
It works normally always, the radio frequency link of 2~No. 5 RRU is closed when no train passes through；Either one always vehicle when, No. 1 will be initially entered
Or the coverage area of No. 6 RRU, BBU will test service access, then BBU passes through the rf chain of 2~No. 5 RRU of Ir interface notification
It opens on road.The time delay opened from BBU detection business to RRU is Millisecond, is calculated according to 350km/h hours, train operation distance
It is several meters or so, (coverage distance of general each RRU in 500m or more), therefore not still in the coverage area of 1 or No. 6 RRU
The radio frequency link that will cause 2~No. 5 RRU has little time the case where opening.
When train outputs BBU cell, BBU detects that this cell without business, does not i.e. have all in 6 RRU coverage areas
Business then closes the radio frequency link of 2~No. 5 RRU, into standby mode.In train temporary parking, since BBU cell is still deposited
It is not turned off in the radio frequency link of business, 2~No. 5 RRU, does not influence regular traffic.Since train is there are certain running interval,
Each BBU lower most of the time without business, only just needs the radio frequency link of 2~No. 5 RRU among unlatching when train passes through, can
Significantly to save power consumption, 60%~70% ratio of RRU power consumption is accounted for according to radio frequency link and is calculated, 2~No. 5 RRU can save power consumption
60%~70% or so.
In addition, to avoid No. 1 or No. 6 RRU failures make BBU that can not detect service access, 2~No. 5 RRU are not led to also not
The case where unlatching notice can be received in time, BBU need to obtain No. 1 and No. 6 RRU and have the time of service access, when continuing to exceed XX
When business is not detected by described No. 1 or No. 6 RRU accesses in minute, then determine in described No. 1 or No. 6 RRU failures or link
It is disconnected, No. 2 or No. 3 RRU are converted into always-on at this time.When such as determining No. 1 RRU failure, subsequent train from No. 1 direction RRU into
Enter into normal coverage areas, BBU can detect service access by No. 2 RRU and notify other RRU normally-open.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention, it is all
Made any modifications, equivalent replacements, and improvements etc. within the spirit and principles in the present invention, should be included in protection of the invention
Within the scope of.
