如图 1所示， 本发明实施方式的广播控制信道信息倒换方法包括： 步骤 101 , 基站控制器判断基站收发信机上的收发单元需要进行广播控 制信道数据倒换。 As shown in FIG. 1, the broadcast control channel information switching method in the embodiment of the present invention includes: Step 101: The base station controller determines that the transceiver unit on the base transceiver station needs to perform broadcast control channel data switching.
BTS在收发单元上发生故障 (高级数据链路控制链路断开或者在收发单 元发生软件或硬件故障）时， 通过 "状态已改变消息" 向 BSC上报。 人工强 制倒换情境下， BSC可获知进行人工强制进行广播控制信道倒换的命令。  When the BTS fails on the transceiver unit (the advanced data link control link is disconnected or a software or hardware failure occurs in the transceiver unit), the BSC reports to the BSC via the "Status Changed Message". In the case of artificial forced reversal, the BSC can learn the command to manually force the broadcast control channel switching.
基站控制器根据以下条件之一判断收发单元需要进行广播控制信道数据 倒换：  The base station controller determines that the transceiver unit needs to perform broadcast control channel data switching according to one of the following conditions:
检测到所述收发单元上高级数据链路控制链路断开的告警；  Detecting an alarm that the advanced data link control link is disconnected on the transceiver unit;
检测到所述收发单元的发生软件或硬件故障的通知； 收到需对所述收发单元进行人工强制进行广播控制信道倒换的命令。 基站控制器收到上述告警或通知时， 如果本基站控制器正在对此收发单 元执行 BCCH倒换， 则放弃本次告警或通知导致的触发信息， 如果本基站控 制器正在执行独立专用控制信道 ( Separate Dedicated Control Channel, 简称 SDCCH )动态配置， 则在数据区中记录下有关信息， 等待执行完 SDCCH动 态配置后再执行 BCCH倒换。 Notifying that the transceiver unit is notified of a software or hardware failure; A command is received that manually forces the transceiver unit to perform a broadcast control channel switchover. When the base station controller receives the foregoing alarm or notification, if the base station controller is performing BCCH switching on the transceiver unit, the base station controller is abandoning the trigger information caused by the current alarm or the notification, if the base station controller is performing the independent dedicated control channel (Separate) Dedicated Control Channel (SDCCH for short) Dynamic configuration, the relevant information is recorded in the data area, and the BCCH switching is performed after the SDCCH dynamic configuration is executed.
基站控制器检测到基站收发信机上的收发单元发生故障后， 启动倒换定 时器 （TIME1 ) , 在此倒换定时器的定时时间到达时此收发单元的故障仍未 消除的情况下， 选择目标收发单元， 倒换定时器的有效时间内此收发单元的 故障消除， 则结束倒换流程。  After detecting that the transceiver unit on the base transceiver station fails, the base station controller starts the switching timer (TIME1), and selects the target transceiver unit when the failure of the transceiver unit is not eliminated when the timing of the switching timer arrives. If the fault of the transceiver unit is cleared within the valid time of the switching timer, the switching process ends.
倒换定时器的定时时间到达时， BSC判断故障收发单元是其所属小区中 唯——个收发单元、 本小区的此收发单元参与跳频、 本小区不允许 BCCH倒 换、 或者此时 BTS的 OMU的 LAPD被闭塞， 则结束倒换流程。  When the timing of the switching timer arrives, the BSC determines that the faulty transceiver unit is the only transceiver unit in the cell to which it belongs, the transceiver unit of the local cell participates in frequency hopping, the cell does not allow BCCH switching, or the OMU of the BTS at this time. When the LAPD is blocked, the switching process ends.
倒换定时器的定时时间到达时， 找不到与此收发单元属于同一小区且处 于正常收发状态的目标收发单元则重新开启倒换定时器等待下一次查询。  When the timing of the switching timer arrives, the target transceiver unit that is in the same cell as the transceiver unit and is in the normal receiving and receiving state cannot be turned on to restart the switching timer for the next inquiry.
步骤 102, 将此收发单元上的广播控制信道数据倒换到与此收发单元属 于同一小区且处于正常收发状态的目标收发单元上。  Step 102: The broadcast control channel data on the transceiver unit is switched to a target transceiver unit that is in the same cell as the transceiver unit and is in a normal transceiver state.
进行 BCCH数据倒换的实质是在一收发单元需要进行 BCCH数据倒换 时， 用与此收发单元属于同一小区且处于正常收发状态的目标收发单元继承 此收发单元上的逻辑配置， 使基站传送的无线数据继续有效。 进行倒换的 BCCH数据中包括载频的状态、 载频的逻辑位置、 信道数据。 倒换过程中， 以下参数不进行倒换： 功放类别、 载频类型、 频点、 跳频方式、 终端设备号 ( TEI ) 。  The essence of performing BCCH data switching is that when a transceiver unit needs to perform BCCH data switching, the target transceiver unit that belongs to the same cell as the transceiver unit and is in the normal transmission and reception state inherits the logical configuration on the transceiver unit, so that the wireless data transmitted by the base station is transmitted. Continue to be effective. The BCCH data to be switched includes the state of the carrier frequency, the logical position of the carrier frequency, and the channel data. During the switching process, the following parameters are not switched: Amplifier class, carrier frequency type, frequency point, frequency hopping mode, and terminal equipment number (TEI).
选择目标收发单元时， 在载频混插情况下， 基站控制器优先选用与故障 收发单元承载载波类型 （即 BCCH载频为单载波载频或双载波载频）相同的 收发单元作为目标收发单元， 在没有相同类型的 TRU情况下， 选用其它类型 的 TRU。  When the target transceiver unit is selected, in the case of carrier frequency intermixing, the base station controller preferentially selects the transceiver unit with the same carrier type (ie, the BCCH carrier frequency is the single carrier carrier frequency or the dual carrier carrier frequency) as the target transceiver unit. In the absence of the same type of TRU, other types of TRUs are used.
选择目标收发单元时， 基站控制器还可以优先选择没有配置基带跳频的 收发单元作为目标收发单元。如果 BCCH倒换中候选 TRU选择的是参与基带 跳频的 TRU, 则在 BCCH倒换成功完成后 （即收到 BTS回复的 BCCH倒换 成功且延时检查 BCCH的 TRU处于正常状态时 ) ,启动基带跳频 TRU倒换， 将故障 TRU从原基带跳频组移除， 更新基带跳频表。 When the target transceiver unit is selected, the base station controller can also preferentially select the baseband frequency hopping without configuration. The transceiver unit acts as a target transceiver unit. If the candidate TRU in the BCCH switching selects the TRU participating in the baseband frequency hopping, after the BCCH switching is successfully completed (that is, when the BCCH switching of the BTS reply is successful and the TRU of the BCCH is delayed, the baseband frequency hopping is started) The TRU is switched, the faulty TRU is removed from the original baseband frequency hopping group, and the baseband hopping table is updated.
基站控制器选择出目标收发单元后， 向故障收发单元和目标收发单元发 送闭塞消息， 目标收发单元上存在话务时， 将话务转移至其它处于正常收发 状态的收发单元后， 执行倒换命令， 完成倒换后基站控制器向故障收发单元 和目标收发单元发送解闭塞消息。  After the base station controller selects the target transceiver unit, it sends an occlusion message to the fault transceiver unit and the target transceiver unit. When there is traffic on the target transceiver unit, the traffic is transferred to other transceiver units in the normal transmission and reception state, and the switching command is executed. After the completion of the switching, the base station controller sends a de-blocking message to the fault transceiver unit and the target transceiver unit.
具体实现中， BSC将原 BCCH的 TRU和候选的将配置为新 BCCH的 TRU 在数据库中进行闭塞，将相关 TRU的业务切换或关闭，设置定时器（ TIME2 ), 在定时器 （TIME2 ) 的定时时间到达时， 向故障收发单元和目标收发单元发 送闭塞消息， 设置定时器（TIME3 ) , 在定时器（TIME3 )的时间内收到 BTS 闭塞成功回复后， 下发 BCCH倒换命令， 并开启定时器（TIME4 ) , BTS执 行 BCCH倒换操作， 改变参与 BCCH倒换的两个逻辑 TRU和物理 TRU的对 应关系，将参与 BCCH倒换的两个 TRU的逻辑参数进行交换，在倒换成功后 上报 "BCCH倒换确认消息" ， 在倒换失败时上报 "BCCH倒换失败消息" ， BSC在定时器（TIME4 )时间内收到" BCCH倒换确认消息"后， BSC下发解 闭 TRU 消息将参与 BCCH倒换过程的两个 TRU解闭塞； BSC在定时器 ( TIME4 )时间内收到" BCCH倒换失败消息" 后， 则获知未倒换成功， 结束 本次倒换流程。  In a specific implementation, the BSC occludes the TRU of the original BCCH and the candidate TRU that will be configured as the new BCCH in the database, switches or shuts down the service of the associated TRU, sets a timer (TIME2), and is at the timing of the timer (TIME2). When the time arrives, the acknowledgment message is sent to the faulty transceiver unit and the target transceiver unit, and the timer (TIME3) is set. After the BTS occlusion is successfully replied within the time of the timer (TIME3), the BCCH switching command is issued, and the timer is started. (TIME4), the BTS performs a BCCH switching operation, and changes the correspondence between the two logical TRUs and the physical TRUs that are involved in the BCCH switching, and exchanges the logical parameters of the two TRUs that are involved in the BCCH switching, and reports the "BCCH switching confirmation message" after the successful switching. " ", when the switching fails, the "BCCH switching failure message" is reported. After the BSC receives the "BCCH switching confirmation message" in the timer (TIME4), the BSC sends the TRU solution to the BCCH switching process. Blocking; after receiving the "BCCH switching failure message" in the timer (TIME4), the BSC knows that the switchover is successful, and ends the switchover. Cheng.
人工强制 BCCH倒换是 BCCH倒换的一个特殊方式， 以下对 "人工强制 BCCH倒换触发" 和 "人工强制 BCCH倒换检查" 进行特别说明， 其它内容 与上述方法相同。 人工强制 BCCH倒换由后台发起。 人工强制 BCCH倒换支 持两种方式： 方式一， 前台选择候选 TRU, 即人工发起 BCCH倒换时， 由 BSC选择目标 TRU进行 BCCH倒换。 对于单 TRU小区， BCCH倒换开关未 打开， BCCH所在的机架上没有小区的其他 TRU, 后台不能发起人工强制 BCCH倒换。 方式二， 后台指定候选 TRU, 即人工发起 BCCH倒换时， 由操 作者选择候选 TRU, 候选 TRU必须与 BCCH的 TRU在同一个机架上。 前台 将 BCCH倒换到后台指定的 TRU。 对于单 TRU小区、 BCCH倒换开关未打 开、 候选 TRU与 BCCH不在同一机架、 候选 TRU的载频类型与 BCCH所在 的载频类型不一致时， 后台不能发起人工强制 BCCH倒换。 Manual forced BCCH switching is a special method of BCCH switching. The following describes the "manual forced BCCH switching trigger" and "manual forced BCCH switching check". The other contents are the same as the above methods. Manual forced BCCH switching is initiated by the background. Manual forced BCCH switching supports two modes: Mode 1: When the foreground selects a candidate TRU, that is, when the BCCH switching is manually initiated, the BSC selects the target TRU to perform BCCH switching. For a single TRU cell, the BCCH switch is not enabled. There is no other TRU in the cell where the BCCH is located. The manual cannot force the BCCH switchover. In the second mode, the candidate TRU is specified in the background, that is, when the BCCH switching is manually initiated, the candidate TRU is selected by the operator, and the candidate TRU must be in the same rack as the TRU of the BCCH. The foreground switches the BCCH to the TRU specified in the background. For a single TRU cell, the BCCH switch is not hit. When the candidate TRU and the BCCH are not in the same chassis, and the carrier frequency type of the candidate TRU is different from the carrier frequency of the BCCH, the manual forced BCCH switching cannot be initiated in the background.
BSC收到进行人工强制进行广播控制信道倒换的命令后， 先检查当前是 否能够进行倒换，如允许 BCCH倒换开关是否打开，同时如果是前台指定 TRU 方式，则判断下发的 TRU是否是 BCCH的 TRU;如果是后台指定 TRU方式， 则判断下发的 TRU架框槽是否合法，与 BCCH的 TRU的载频类型是否一致， 是否在同一机架上， 检查不通过， 则回复否决同时携带错误原因码。 如果检 查通过， 则在数据区中记录下本次倒换的有关信息。  After receiving the command to manually perform the broadcast control channel switching, the BSC checks whether the current TCCH switch is enabled, and if the BCCH switch is enabled, and if the TRU mode is specified in the foreground, it is determined whether the delivered TRU is the TRU of the BCCH. If the TRU mode is specified in the background, it is determined whether the TRU frame slot is valid, and whether the carrier frequency of the TRU of the BCCH is the same, whether it is in the same rack, if the check fails, the response is rejected and the error reason code is carried. . If the check is passed, the information about this switch is recorded in the data area.
