Fig. 3 be the embodiment of the present invention two processing radio frequency impairments method flow chart, as shown in figure 3, can with including
Following steps：
Step 101, RRU operation and maintenance sub system can be responsible for timing (assuming that timer is T1) detection radio frequency and far put unit
Various failures, and master control borad of the report and alarm to BBU；
After step 102, master control borad receive alarm, in oneself alarm list, the species of the alarm is searched, and confirms that it is
It is no to influence the mode of operation (Op State) of corresponding carrier frequency, if influenceed, the inaccessible carrier frequency, and report the inaccessible shape of the carrier frequency
State gives BSC (base station controller), if do not influenceed, terminates.
BSC has the distribution that a main function is exactly control channel, if the state of the carrier frequency is inaccessible, then letter
Road would not be assigned on the carrier frequency.If the carrier frequency of alarm is not inaccessible, state does not also offer BSC, then BSC just will be considered that
The carrier frequency is available.
Step 103, after receiving BSC status confirmation messages, master control borad is first begin to search whether on the RRU to break down
There is the radio frequency TRX (RRU there may be multiple radio frequency TRX) of backup, if it is not, into step 104, if backup
Radio frequency TRX, then into step 105；
Step 104, master control borad are searched with fault carrier frequency same cells in the RRU lists of all working of this base station
RRU, and check whether it has the radio frequency TRX of backup, if so, then entering step 105, if it is not, this fault carrier frequency is not
Dynamic switches, it is necessary to manual intervention；
Step 105, after finding the radio frequency TRX of backup, the dynamic baseband radio incidence relation distribution of master control borad progress, remove
The original radio frequency binding relationship of fault carrier frequency, establishes new binding relationship；
And new incidence relation and relevant parameter are handed down to related single-boards, for example, FS plates, BP (LTE Baseband Processing Unit) and
RRU plates；
After step 106, new radio frequency are assigned, master control borad unblocks the carrier frequency, and uploaded state is to BSC, so as to reach
Fault carrier frequency self- recoverage.
In addition, RRU alarm report, it is contemplated that the situation that alarm is frequently overturn, delay can be taken to report.
It is bad when for example good during a failure, then corresponding alarm will report for a moment caused by it, recover for a moment, have in fact
It might as well badly allow its time that breaks down longer when good when when a little.Once the corresponding carrier frequency of report and alarm is possible to occlusion, but
Alarm can also recover at once, so RRU can be delayed a period of time in alarm report, if in the period, alarm is also deposited
Report again.
Webmaster may also set up fault carrier frequency automatic transfer switch；
The bad influence to systematic function when webmaster may also set up good when fault carrier frequency recovers delay to prevent carrier frequency, can be upper
State and delay judgement processing is carried out in step 103 (for example, after receiving BSC confirmation message, occurring again after the certain time that is delayed
The radio frequency TRX of backup is searched whether on the RRU of failure).In order to allow attendant timely to solve the radio frequency list to break down
Plate, BBU can recover fault carrier frequency statistical report to webmaster, and making attendant which RRU understood in time, there occurs failure load
Frequency switches.
It is contemplated that when failure radio frequency veneer recovers normal after being replaced, the carrier frequency of this veneer of moving out can be moved back to, so as to not
Influence the load of other radio frequency veneers.
The fault carrier frequency switching method of radio frequency stretch system provided in an embodiment of the present invention, core are to monitor RRU in real time
Running status, if faulty master control borad of the report and alarm to BBU, master control borad can carry out state according to alarm species
Solution occlusion and notify BSC, then system passes through dynamically adjusts carrier frequency and light exchange, base-band resource, radio frequency RRU in base station side
Incidence relation between resource enables the radio frequency resource of backup, so as to dynamically recovering the work of fault carrier frequency.In radio frequency TRX
During incidence relation adjustment, because only have modified failure radio frequency TRX inherent annexation, other carrier frequency and radio frequency and base band
Corresponding relation do not change, therefore do not interfere with other working carrier frequencies.And fault carrier frequency automatically switches, can also recover quickly
Work, the network performance of this cell is influenceed little.
Fig. 4 show the structured flowchart of the GSM radio frequency stretch systems of the embodiment of the present invention one, and the system includes：Master control borad,
LTE Baseband Processing Unit (BP), light power board (FS) and RF remote unit (RRU).
In BBU, master control borad is responsible for alarm and carrier frequency condition managing and relevant parameter configuration, and BSC carrier frequency, base band money
The incidence relation distribution in source, radio frequency RRU resources and FS passages.In RRU, the operation for the timing detection veneer that high layer software is responsible for
State, if alerting, then report BBU master control borad.
Such as Fig. 4, two carrier frequency TRXa, TRXb in a BSC cell, initial incidence relation is respectively TRXa- ＞
1.-＞ 2.-＞ 3., TRXb- ＞ 4.-＞ 5.-＞ 6., if TRXb radio frequency part (i.e. RRU2 R1) breaks down, according to
Fig. 1 flows, R2 is found in the backup radio frequency resource of this RRU veneers, may become after the completion of switching TRXb- ＞ 4.-＞ 5.-
＞ 7., so as to reach the automatic switchover of fault carrier frequency.
Such as Fig. 5, BSC two carrier frequency TRXa, TRXb, initial incidence relation be respectively TRXa- ＞ 1.-＞ 2.-＞ 3.,
4. 5.-＞ is 6., small at this according to Fig. 1 flows if TRXb radio frequency part (i.e. RRU2 R1) breaks down by-＞ by TRXb- ＞
Backup radio frequency resource (i.e. RRU1 R1) is found on other RRU veneers in area, may become after the completion of switching TRXb- ＞ 4.-
＞ 5.-＞ 7., so as to reach the automatic switchover of fault carrier frequency.
For Fig. 5, if the radio frequency TRX of failure is maintained (such as RRU2 R1) after personnel change, on other RRU veneers
Backup radio frequency is enabled, in order to not influence original radio frequency veneer (RRU1) load, original carrier frequency (TRXb) can be recovered
On radio frequency veneer (RRU2) after to replacing.This requires our master control borad to pay close attention to the recovery situation of failure radio frequency, if extensive
Multiple, the radio frequency that will trigger carrier frequency is refunded.
According to practical situations, during for base-band resource failure, during if backup base-band resource, this hair can also refer to
It is bright, defect baseband resource is automatically switched, so as to enable resource backup.
