Said base station controller also is used for judging that according to one of following condition the Transmit-Receive Unit needs carry out the BCCH data and switch: detect the alarm that the High-Level Data Link Control link breaks off on the said Transmit-Receive Unit; Detect the generation software of said Transmit-Receive Unit or the notice of hardware fault; Receiving needs said Transmit-Receive Unit is carried out the artificial order that BCCH is switched of forcing to carry out.
Said base station controller also is used under carrier frequency mixed insertion situation, preferentially selects for use the Transmit-Receive Unit identical with fault Transmit-Receive Unit bearing carrier wave type as the target Transmit-Receive Unit.
Said base station controller also is used for Transmit-Receive Unit that preferential selection do not dispose baseband hopping as the target Transmit-Receive Unit.
As shown in Figure 1, the broadcast control channel information reverse method comprises:
When BTS High-Level Data Link Control link on Transmit-Receive Unit breaks off or when Transmit-Receive Unit generation software or hardware fault, report to BSC through " state has changed message ".Under the artificial Forced Switch situation, BSC can know that carrying out artificial pressure carries out the order that BCCH is switched.
Base station controller judges that according to one of following condition the Transmit-Receive Unit needs carry out the BCCH data and switch:
Detect the alarm that the High-Level Data Link Control link breaks off on the said Transmit-Receive Unit;
Detect the generation software of said Transmit-Receive Unit or the notice of hardware fault;
Receiving needs said Transmit-Receive Unit is carried out the artificial order that BCCH is switched of forcing to carry out.
When base station controller is received above-mentioned alarm or notice; If this base station controller is carried out BCCH to this Transmit-Receive Unit and is switched; Then abandon the trigger message that this alarm or notice cause, if this base station controller is being carried out Separate Dedicated Control Channel (Separate Dedicated Control Channel is called for short SDCCH) dynamic-configuration; Then in the data field, note for information about, wait for executing and carry out BCCH again after the SDCCH dynamic-configuration and switch.
Base station controller judges that the Transmit-Receive Unit on the base station transceiver need carry out after the BCCH data switch; Start and switch timer (TIME1); Under the situation that the fault of this Transmit-Receive Unit is eliminated not yet when this timing of switching timer arrives; The select target Transmit-Receive Unit is switched the fault of this Transmit-Receive Unit in effective time of timer and is eliminated, and then finishes to switch flow process.
When switching the timing arrival of timer; BSC failure judgement Transmit-Receive Unit is that this Transmit-Receive Unit participation frequency hopping, this sub-district of a unique Transmit-Receive Unit, this sub-district do not allow BCCH to switch in its affiliated subdistrict, perhaps the LAPD of the OMU of BTS is then finished to switch flow process by obturation at this moment.
When the timing of switching timer arrives, can not find target Transmit-Receive Unit that Transmit-Receive Unit therewith belongs to same sub-district and be in normal reiving/transmitting state and then open again and switch timer and wait for inquiry next time.

During the select target Transmit-Receive Unit; Under carrier frequency mixed insertion situation; Base station controller preferentially selects for use the Transmit-Receive Unit identical with fault Transmit-Receive Unit bearing carrier wave type (being that the BCCH carrier frequency is single carrier carrier frequency or two carrier wave carrier frequency) as the target Transmit-Receive Unit; Do not having to select the TRU of other type for use under the TRU situation of same type.
During the select target Transmit-Receive Unit, base station controller preferentially selection do not dispose baseband hopping Transmit-Receive Unit as the target Transmit-Receive Unit.If that candidate TRU selected during BCCH switched is the TRU that participates in baseband hopping; Then switch and complete successfully back (when receiving that promptly TRU that BCCH that BTS replys switches success and time-delay inspection BCCH is in normal condition) at BCCH; Starting baseband hopping TRU switches; Fault TRU is removed from former base band frequency hopping group, upgrade the baseband hopping table.
After base station controller is selected the target Transmit-Receive Unit; Send block message to fault Transmit-Receive Unit and target Transmit-Receive Unit; When having traffic on the target Transmit-Receive Unit; After traffic is transferred to other Transmit-Receive Unit that is in normal reiving/transmitting state, carries out and switch order, accomplish switch the back to the fault Transmit-Receive Unit with the target Transmit-Receive Unit transmission separate block message.
In concrete the realization, BSC carries out obturation with the TRU of former BCCH and candidate's the TRU that will be configured to new BCCH in database, with the business switching of relevant TRU or close; Timer (TIME2) is set, when the timing of timer (TIME2) arrives, sends block message to fault Transmit-Receive Unit and target Transmit-Receive Unit; Timer (TIME3) is set, receive that in the time of timer (TIME3) the BTS obturation is successfully replied after, issue BCCH and switch order; And opening timing device (TIME4); BTS carries out the BCCH switching operation, changes two logic TRU participating in that BCCH switches and the corresponding relation of physics TRU, and the logic parameter of two TRU that participation BCCH is switched exchanges; After switching successfully, report " BCCH switches acknowledge message "; The time report " BCCH switches failed message " switching failure, BSC is timer (TIME4) is received " BCCH switches acknowledge message " in the time after, and BSC issues to separate and closes two TRU that TRU message will participate in the BCCH reversed process and separate obturation; BSC is then known and is not switched successfully timer (TIME4) is received " BCCH switches failed message " in the time after, finishes this and switch flow process.
Artificial to force BCCH to switch be the particular form that BCCH switches, and below " the artificial BCCH that forces switches triggerings " and " manual work pressure BCCH switches inspection " specified that other content is identical with said method.Artificial pressure BCCH switches by the backstage and initiates.The artificial BCCH that forces switches the support dual mode: mode one, candidate TRU is selected on the foreground, when promptly artificial initiation BCCH switches, carries out BCCH by BSC select target TRU and switches.For single TRU sub-district, BCCH switches switch and does not open, and does not have other TRU of sub-district on the frame at BCCH place, and the backstage can not be initiated the artificial BCCH of pressure and switched.Mode two, backstage designate candidate TRU, the promptly artificial BCCH that initiates selects candidate TRU by the operator when switching, candidate TRU must with the TRU of BCCH on same frame.The foreground is switched to BCCH the TRU of backstage appointment.For single TRU sub-district, BCCH switch that switch is not opened, candidate TRU and BCCH not when the carrier frequency Type-Inconsistencies at the carrier frequency type of same frame, candidate TRU and BCCH place, the backstage can not be initiated the artificial BCCH of pressure and switched.
BSC receive carry out artificial force to carry out order that BCCH switches after; Check current whether can switching earlier; As allow BCCH to switch switch whether to open, simultaneously if the TRU mode is specified on the foreground, judge then whether the TRU that issues is the TRU of BCCH; If the TRU mode is specified on the backstage, judge then whether the TRU frame-saw groove that issues is legal, whether consistent with the carrier frequency type of the TRU of BCCH, on same frame, inspection is not passed through, and then replys to veto and carries the error reason sign indicating number simultaneously.If inspection is passed through, then in the data field, note this and switch for information about.
