Hop count is initiated by High-Level Data Link Control broadcast to each radio-frequency apparatus according to the setting cycle to detect；
According to the hop count of each radio-frequency apparatus detected, to each radio-frequency apparatus down distributing configuration data；And according to the hop count of each radio-frequency apparatus detected, set up the advanced data link control channel of each radio-frequency apparatus.
In a step 101, the step of rf control unit is locked the hop count of each radio-frequency apparatus of networking of connecting can specifically include：
Rf control unit saves as the hop count of each radio-frequency apparatus detected the hop count after locking；Number.
If step 102, having radio-frequency apparatus to bypass, the rf control unit issues corresponding configuration data according to the hop count after locking to the radio-frequency apparatus that bypass changeover does not occur.
Wherein, rf control unit is according to the hop count after locking, and the detailed process for issuing corresponding configuration data to the radio-frequency apparatus that bypass changeover does not occur can include：
Initiate High-Level Data Link Control to broadcast, the sequence number of the radio-frequency apparatus of bypass changeover does not occur described in acquisition, and determine the sequence number after corresponding locking；

According to the hop count after the locking found, corresponding configuration data is issued to the radio-frequency apparatus that bypass changeover does not occur, for example：The inclination angle of such as antenna, the power running parameter of transmitting.
Further, after radio-frequency apparatus is bypassed, the radio frequency bypass-switching contr method can also include the process for setting up link, be specially：
According to High-Level Data Link Control（HDLC) broadcast, the real-time hop count of the radio-frequency apparatus of bypass changeover does not occur according to described in the acquisition of setting cycle；
According to the real-time hop count of the radio-frequency apparatus that bypass changeover does not occur, the advanced data link control channel of the radio-frequency apparatus of bypass changeover does not occur described in foundation.
Further, after radio-frequency apparatus is bypassed, the radio frequency bypass-switching contr method may be used also
With the process of the radio-frequency apparatus including determining to occur bypass changeover, it is specially：
Broadcasted according to High-Level Data Link Control, the real-time hop count of the radio-frequency apparatus of bypass changeover does not occur according to described in the acquisition of setting cycle（The real-time hop count of the radio-frequency apparatus after bypass changeover can be obtained）；According to the real-time hop count of hop count and the radio-frequency apparatus that bypass changeover does not occur after the radio-frequency apparatus locking that bypass changeover does not occur, it is determined that occurring the radio-frequency apparatus of bypass changeover.

Embodiment two
Fig. 2 is the flow chart for the radio frequency bypass-switching contr method that the embodiment of the present invention two is provided, as shown in Fig. 2 on the basis of embodiment one, the radio frequency bypass-switching contr method can specifically include：Step 201, REC can be given tacit consent in HOP detection modes, concentrating the O＆M stage, REC is detected to RE initiations HOP according to the setting cycle and is preserved result of detection, and result of detection can be included in the hop count during RE of HOP detection modes hop count, generally normal work；
Step 202, REC initiate HDLC broadcast to obtain and preserve each RE sequence number according to the setting cycle to RE.The sequence number of the RE judges in the link setup that the step can be not used in HDLC, and is used as business ancillary data management；Step 201 can be performed simultaneously with step 202, can be first carried out step 201 and be performed step 202 again, can also be first carried out step 202 and be performed step 201 again.
The hop count of step 203, REC based on HOP detection modes can recognize the RE of physics, be that RE sets up HDLC passages, and corresponding configuration data is issued into RE.
After step 204, base station operation maintenance personnel are opened station and completed, or user installation is completed, O＆M terminates, a very long time base station REC and RE steady operations, it is necessary to steady from concentrating the O＆M stage to enter
Determine the operation phase, upper system can notify REC to carry out pattern switching by locking mode switching command, and REC is received after locking mode switching command, the RE of all series connection networkings can be switched to HOP locking modes.And the RE of all ring-shaped networks still keeps hop count detection mode, the RE of ring-shaped network can improve link stability by switching, without using bypass changeover.
Step 205, REC by each RE detected from HOP detection modes be switched to HOP locking modes when HOP save as " locking after HOP ", sequence number and save as " sequence number after locking ".Wherein, " HOP after locking ", " sequence number after locking " can save as read-only file, not allow the RE of HOP locking modes to change, even if restarting to ensure to reset in stable operation stage REC, can continue to data expendable locked before continuing to use.In addition, REC can also notify each RE in series connection networking, forbid the positive returns after the change of itself hop count is found of each RE in series connection networking, it is ensured that prime RE bypasses do not influence follow-up RE to work on；
Step 206, REC continue to initiate HDLC broadcast, obtained RE is not re-used as assistance data in the sequence number of HOP locking modes, and RE physical location is positioned as user, the sequence number of acquisition is searched into matching in " sequence number after locking ", can be matched under normal circumstances some " sequence number after locking ".Represent that attendant has accessed new RE if without occurrence, REC can not be continued with.
Step 207, REC are found after " sequence number after locking ", are found corresponding " HOP after locking " according to " sequence number after locking " that finds；
Step 208, REC are found after " HOP after locking ", then are compared with the RE of the HOP locking modes carried in HDLC broadcast " real-time HOP "；If some RE in series connection networking meets with powered-off fault, RE hardware auto by pass switching, now, " the real-time HOP " for occurring the RE and its follow-up RE of bypass changeover are different from " HOP after locking ".REC can recognize which RE the RE for occurring bypass changeover is specifically.
Step 209, REC are checked using " HOP after locking " with user configuring, configurations of the RE of bypass changeover before locking are not occurred, so as to ensure that the RE that bypass changeover does not occur can be according to the configuration before locking and state normal work；
For example：Configuration and physics corresponding relation before locking is as follows：The first order on the chain of series connection networking
RE standing wave thresholdings are " 1.5 ", and second level RE standing wave thresholdings are " 1.8 ", and third level RE standing wave thresholdings are " 2.0 ".Even if second level RE is bypassed after locking, third level RE can also work by the configuration standing wave thresholding of " 2.0 ", will not be taken as the second level by REC to switch to its standing wave thresholding " 1.8 " by mistake.
Step 210, REC " real-time HOP " based on the RE real-time detected (are obtained in step 208）, set up HDLC passages of the RE in HOP locking modes.
In stable operation stage, the RE of series connection networking is in HOP locking modes, still the cycle detects each RE HOP to REC, but obtained RE real-time HOP is not used in the judgement of HDLC link setups/tear open chain, and can be used for bypass changeover alarm, when certain one-level RE is bypassed total HOP reductions after switching, external user can alert the exception for perceiving RE by " HOP is inconsistent ", and then arrange personnel's troubleshooting.
For example：3 grades of series connection RE networks of user configuring one, the standing wave thresholding of the first order to third level RE is " 1.5 ", " 1.8 ", " 2.0 " respectively；Three RE are physically accessed, its HOP is respectively " 0 ", " 1 ", " 2 ", and sequence number is " AA ", " BB ", " CC " respectively.Hardware is bypassed after the RE power down in centre position under locking mode, now, if the REC RE for detecting physics first is turned into two from three, user can be set to alert, while by topology scanning process for example：REC initiates HDLC broadcast, and the physical equipment that can perceive the Serial No. " AA " after locking and two RE of " CC " is all present, and its real-time HOP is " 0 " and " 1 " respectively.The HOP that REC can find after Serial No. " AA " the locking corresponding with RE of " CC " after locking in locking data table is " 0 " and " 2 " respectively, and then it is " 1.5 " and " 2.0 " respectively to find the standing wave thresholdings that use of RE of the Serial No. " AA " after locking and " CC ".Because the sequence number after locking and the HOP after locking in stable operation stage are read-only data, do not change, even if so REC is restarted, can also be according to previous lock-out state normal configuration RE.
Further, the embodiment of the present invention can be not used in changing the configuration that RE changes RE every time, and when operation maintenance personnel needs to enter the station preparation dilatation again, can first unlock pattern, for example：Pass through
Upper system sends detection mode switching command to REC, indicate that the RE for networking of connecting is switched to HOP detection modes by REC from HOP locking modes, then physics RE connections are adjusted again, after the completion of construction, are re-executed step 201 and are recovered locking mode.
The present embodiment REC can be locked the hop count of each RE in networking of connecting, when some RE, which meets with powered-off fault, causes RE autos by pass to switch, REC can be according to HOPs of the RE after the locking of HOP detection modes to the RE down distributing configuration datas of bypass changeover do not occur, each RE (except the RE being bypassed) can be ensured by the configuration before locking and operation, so as to lift the reliability of radio frequency unit series connection networking, without additionally increasing the configuration adjustment work of network planning personnel, it is not necessary to change HDLC and CPRI consensus standards；And REC can identify the specific RE that bypasses according to the HOP after the locking that bypass changeover does not occur and the real-time HOP that bypass changeover does not occur, maintain easily.
