Description

用于远端单元开站的方法、基带单元、通信系统和介质 技术领域
本公开的实施例总体涉及通信领域，具体涉及用于多个远端射频单元的开站的方法、基带单元、通信系统和计算机存储介质。
背景技术
当前无线通信系统站点通常包括基带单元(Baseband Unit，BBU)和多个远端射频单元(Remote Radio Unit，RRU)。基带单元用于对通信数据进行编码、调制等处理，以生成待发射信号，以及将待发射信号传输给远端射频单元。远端射频单元用于将待发射信号经由天线进行发射。整个站点的最大功耗可达数千瓦。基带单元的功耗通常比较稳定，但是远端射频单元的功耗通常随着业务变化而变化，高业务负载时功耗高，低业务负载时功耗低。
在站点上电启动后，远端射频单元需要进行校准和驻波检测(也称为开站)。在这一过程中，需要以较高的发射功率发射测试信号。此时，如果所有远端射频单元同时发射测试信号会导致站点功耗达到或接近整站最大功耗水平。在部分电网负荷较重的站点或者电网不太稳定的区域，站点供电可能不能满足以上最大负荷的要求，导致供电单元跳闸或复位，此时整个站点将重启。由于多个远端射频单元的软硬件一致性，可能循环出现以下现象：站点上电启动-多个远端射频单元同时发射测试信号校准-电源过载-掉电，从而导致站点一直在重复启动，无法提供业务。

具体实施方式
以下结合附图对本公开的示范性实施例做出说明，其中包括本公开实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本公开的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
在本文中使用的术语“包括”及其变形表示开放性包括，即“包括但不限于”。除非特别申明，术语“或”表示“和/或”。术语“基于”表示“至少部分地基于”。术语“一个示例实施例”和“一个实施例”表示“至少一个示例实施例”。术语“另一实施例”表示“至少一个另外的实施例”。术语“第一”、“第二”等等可以指代不同的或相同的对象。下文还可能包括其他明确的和隐含的定义。
如上所述，传统方案中，所有远端射频单元同时进行校准和驻波检测导致整个站点供电负荷高，在电网不稳定区域或者供电不足区域 容易导致电源跳闸。此外，多个远端射频单元的软硬件一致性较高，可能导致站点跳闸后重复进行上述启动、校准、掉电过程，无法提供业务。
为了至少部分地解决上述问题以及其他潜在问题中的一个或者多个，本公开的示例实施例提出了一种用于多个远端射频单元的开站的方案。在该方案中，基带单元响应于接收到来自与基带单元相耦接的多个远端射频单元的多个就绪消息，获取用于多个远端射频单元的开站配置数据，开站配置数据指示多个远端射频单元被划分成的多个远端射频单元集以及与多个远端射频单元集相关联的多个开站批次，开站包括校准和驻波检测。随后，基带单元向多个远端射频单元集中的第一远端射频单元集发送启动开站消息，第一远端射频单元集与第一开站批次相关联。接着，基带单元响应于接收到来自第一远端射频单元集的完成开站消息集，向多个远端射频单元集中的第二远端射频单元集发送启动开站消息，第二远端射频单元集与第二开站批次相关联，第二开站批次位于第一开站批次之后。根据本公开的实施例，通过将基带单元所耦接的多个远端射频单元划分为多个开站批次，并在前一批次开站完成后再启动下一批次开站，能够降低基带单元所耦接的多个远端射频单元的开站瞬时总功耗。
在下文中，将结合附图更详细地描述本方案的具体示例。
图1示出了根据本公开的实施例的通信系统100的示例的示意图。通信设备100可以包括基带单元110和与基带单元110相耦接的多个远端射频单元120-1至120-n(下文将远端射频单元统称为120)，其中n大于等于2。
基带单元110可以存储有用于多个远端射频单元120的开站配置数据130。此外，基带单元110也可以从远端维护中心或近端维护台获取开站配置数据130。例如，开站配置数据130可以通过人工远端或近端地经由图形化或者命令行的配置接口而被配置的。
开站配置数据130可以指示多个远端射频单元120被划分成的多个远端射频单元集以及与多个远端射频单元集相关联的多个开站批次。例如，以n＝9为例，开站配置数据可以指示9个远端射频单元被 划分为3个开站批次，每个开站批次3个远端射频单元。例如，开站配置数据的一个示例为：set startupBatch 1 RRU1 RRU2 RRU3；set startupBatch 2 RRU4 RRU5 RRU6；set startupBatch 3 RRU7 RRU8 RRU9，其中set startupBatch表示设置开站批次，上述配置数据设置了第1开站批次，涉及RRU1、RRU2和RRU3，第2开站批次，涉及RRU4、RRU5和RRU6，以及第3开站批次，涉及RRU7、RRU8和RRU9。开站配置数据可以保存为xml文件、数据库文件或者可解析的其他格式。
远端射频单元120在就绪后会向基带单元110发送就绪消息。就绪消息例如可以通过前传链路发送到基带单元110，例如可以通过通用公共无线电接口(Common Public Radio Interface，CPRI)协议或增强通用公共无线电接口(enhanced CPRI，eCPRI)协议。
基带单元110用于响应于接收到来自与基带单元110相耦接的多个远端射频单元120的多个就绪消息，获取用于多个远端射频单元120的开站配置数据130，开站配置数据130指示多个远端射频单元120被划分成的多个远端射频单元集以及与多个远端射频单元集相关联的多个开站批次，开站包括校准和驻波检测；向多个远端射频单元集中的第一远端射频单元集发送启动开站消息，第一远端射频单元集与第一开站批次相关联；以及响应于接收到来自第一远端射频单元集的完成开站消息集，向多个远端射频单元集中的第二远端射频单元集发送启动开站消息，第二远端射频单元集与第二开站批次相关联，第二开站批次位于第一开站批次之后。
由此，通过将基带单元所耦接的多个远端射频单元划分为多个开站批次，并在前一批次开站完成后再启动下一批次开站，能够降低基带单元所耦接的多个远端射频单元的开站瞬时总功耗。
图2示出了根据本公开的实施例的用于多个远端射频单元的开站的方法200的流程图。例如，方法200可以由如图1所示的基带单元110来执行。应当理解的是，方法200还可以包括未示出的附加框和/或可以省略所示出的框，本公开的范围在此方面不受限制。
在框202处，基带单元110接收来自与基带单元110相耦接的多 个远端射频单元120的多个就绪消息。
响应于在框202处基带单元110接收到来自与基带单元110相耦接的多个远端射频单元120的多个就绪消息，在框204处，基带单元110获取用于多个远端射频单元120的开站配置数据130，开站配置数据130指示多个远端射频单元120被划分成的多个远端射频单元集以及与多个远端射频单元集相关联的多个开站批次，开站包括校准和驻波检测。
应当理解，开站批次与远端射频单元集相关联的意思是远端射频单元集在该开站批次进行开站。多个开站批次与多个远端射频单元集相关联的意思是多个远端射频单元集分别在多个开站批次进行开站。
在框206处，基带单元110向多个远端射频单元集中的第一远端射频单元集发送启动开站消息，第一远端射频单元集与第一开站批次相关联。
第一远端射频单元集与第一开站批次相关联的意思是第一远端射频单元集在第一开站批次进行开站。
在框208处，基带单元110接收来自第一远端射频单元集的完成开站消息集。
响应于在框208处基带单元110接收到来自第一远端射频单元集的完成开站消息集，在框210处，基站单元110向多个远端射频单元集中的第二远端射频单元集发送启动开站消息，第二远端射频单元集与第二开站批次相关联，第二开站批次位于第一开站批次之后。
第二远端射频单元集与第二开站批次相关联的意思是第二远端射频单元集在第二开站批次进行开站。
上述过程可以按照多个启动批次顺序进行，直至多个启动批次的多个远端射频单元集完成开站。例如，基带单元110还可以响应于接收到来自第二远端射频单元集的完成开站消息集，向多个远端射频单元集中的第三远端射频单元集发送启动开站消息，第三远端射频单元集与第三开站批次相关联，第三开站批次位于第二开站批次之后。
由此，通过将基带单元所耦接的多个远端射频单元划分为多个开站批次，并在前一批次开站完成后再启动下一批次开站，能够降低基 带单元所耦接的多个远端射频单元的开站瞬时总功耗，从而避免所有远端射频单元同时进行校准和驻波检测导致整个站点供电负荷高，在电网不稳定区域或者供电不足区域容易导致电源跳闸的情况，以及避免由于多个远端射频单元的软硬件一致性较高可能导致站点跳闸后重复进行启动、校准、掉电过程而无法提供业务的情况。
图3示出了根据本公开的实施例的用于多个远端射频单元的开站的过程300的流程图。应当理解的是，方法300还可以包括未示出的附加框和/或可以省略所示出的框，本公开的范围在此方面不受限制。应当理解，虽然图3中示出了3个批次的远端射频单元集，但是这只是举例说明，可以具有2个批次的远端射频单元集或者多于3个批次的远端射频单元集，本公开的范围在此不受限制。
如图3所示，基带单元和3个批次的远端射频单元集在301处开始上电启动并进行软件加载和运行。
随后，各个批次的远端射频单元集在302、303、304处向基带单元发送就绪消息。
基带单元在305处向第1批次的远端射频单元集发送启动开站消息。第1批次的远端射频单元集在306处进行开站，也就是校准和驻波检测。在开站完成后，第1批次的远端射频单元集在307处向基带单元发送完成开站消息。
基带单元在308处向第2批次的远端射频单元集发送启动开站消息。第2批次的远端射频单元集在309处进行开站，也就是校准和驻波检测。在开站完成后，第2批次的远端射频单元集在310处向基带单元发送完成开站消息。
基带单元在311处向第3批次的远端射频单元集发送启动开站消息。第3批次的远端射频单元集在312处进行开站，也就是校准和驻波检测。在开站完成后，第3批次的远端射频单元集在313处向基带单元发送完成开站消息。至此，3个批次的远端射频单元集完成开站。
图4示出了现有技术的功耗与本公开的实施例的功耗的对比400的示意图。如图4的左侧所示，在现有技术中，由于基带单元相耦接的n个远端射频单元同时进行开站(也就是校准和驻波检测)，整个 站点的功耗相当高。与之相对，如图4的右侧所示，根据本公开的实施例，由于基带单元相耦接的n个远端射频单元分成3个批次进行开站，整个站点的功耗得到了极大的降低。应当理解，这里的3个批次仅是举例说明，也可以采用其他批次，例如2个批次，或多于3个批次。
图5示出了根据本公开的实施例的用于获取用于多个远端射频单元的开站配置数据的方法500的流程图。例如，方法500可以由如图1所示的基带单元110来执行。应当理解的是，方法500还可以包括未示出的附加框和/或可以省略所示出的框，本公开的范围在此方面不受限制。
在框502处，基带单元110基于多个就绪消息，确定与基带单元110相耦接的远端射频单元的总数量。
在框504处，基带单元110获取预设开站功耗和当前站点可用功率。预设开站功耗例如是基于远端射频单元的历史开站功耗而生成的。当前站点可用功率例如是基于基带单元110所在站点的可用电力余额而生成的。
在框506处，基带单元110基于预设开站功耗、当前站点可用功率以及总数量，生成开站配置数据。
具体来说，基带单元110可以基于预设开站功耗和当前站点可用功率，确定用于每个开站批次的远端射频单元的最大允许数量。例如，预设开站功耗为P1，当前站点可用功率为T，则用于每个开站批次的远端射频单元的最大允许数量M1＝向下取整(T/P1)。
随后，基带单元110可以基于所确定的最大允许数量和与基带单元110相耦接的远端射频单元的总数量，生成多个开站批次以及多个远端射频单元集。例如，与基带单元110相耦接的远端射频单元的总数量为N，则可以得到S1个开站批次，S1＝向上取整(N/M1)，将多个远端射频单元120可以按照最大允许数量M1和S1个开站批次进行划分，得到S1个远端射频单元集，其中每个远端射频单元集中的远端射频单元的数量不超过M1。
由此，能够实时根据基带单元当前耦接的远端射频单元的总数量、 预设开站功耗和当前站点可用功率，生成开站配置数据，从而使得开站配置数据及时反映基带单元的当前情况。
图6示出了根据本公开的实施例的用于多个远端射频单元的开站的方法600的流程图。例如，方法600可以由如图1所示的基带单元110来执行。应当理解的是，方法600还可以包括未示出的附加框和/或可以省略所示出的框，本公开的范围在此方面不受限制。
在框602处，基带单元110接收来自与基带单元110相耦接的多个远端射频单元120的多个就绪消息。
在框604处，基带单元110基于多个就绪消息，确定与基带单元110相耦接的远端射频单元的总数量。
在框606处，基带单元110获取预设开站功耗和当前站点可用功率。
在框608处，基带单元110基于预设开站功耗、当前站点可用功率以及总数量，生成用于多个远端射频单元120的开站配置数据130，开站配置数据130指示多个远端射频单元120被划分成的多个远端射频单元集以及与多个远端射频单元集相关联的多个开站批次，开站包括校准和驻波检测。
在框610处，基带单元110向多个远端射频单元集中的第一远端射频单元集发送启动开站消息，第一远端射频单元集与第一开站批次相关联。
在框612处，基带单元110监测第一远端射频单元集的开站功耗集并确定开站功耗集中的最大开站功耗。例如，基带单元110可以通过前传链路实时监测第一远端射频单元集中的各个远端射频单元的开站功耗。
在框614处，基带单元110接收来自第一远端射频单元集的完成开站消息集。
响应于在框6104基带单元110接收到来自第一远端射频单元集的完成开站消息集，在框616处，基带单元110确定最大开站功耗是否大于预设开站功耗。
基带单元110如果在框616处确定最大开站功耗小于或等于预设 开站功耗，则向第二远端射频单元集发送启动开站消息，第二远端射频单元集与开站配置数据中的第二开站批次相关联，第二开站批次位于第一开站批次之后(未示出)。
基带单元110如果在框616处确定最大开站功耗大于预设开站功耗，则在框618处基于最大开站功耗、当前站点可用功率以及与基带单元110相耦接的远端射频单元的总数量，更新开站配置数据130。
具体来说，基带单元110可以基于最大开站功耗和当前站点可用功率，确定用于每个剩余开站批次的远端射频单元的最大允许数量，每个剩余开站批次位于第一开站批次之后。例如，最大开站功耗为Pmax，当前站点可用功率为T，则用于每个剩余开站批次的远端射频单元的最大允许数量M2＝向下取整(T/Pmax)。
随后，基带单元110可以基于与基带单元110相耦接的远端射频单元的总数量和第一远端射频单元集中的远端射频单元的数量，确定待开站的远端射频单元的数量。例如，总数量为N，第一远端射频单元集中的远端射频单元的数量为M1，则待开站的远端射频单元的数量为N-M1。应当理解，这是对于第一开站批次是首次开站批次的情况，对于第一开站批次非首次开站批次的情形而言，待开站的远端射频单元的数量可以为N-已开站远端射频单元的数量。
接着，基带单元110可以基于用于每个剩余开站批次的远端射频单元的最大允许数量和待开站的远端射频单元的数量，生成多个剩余开站批次和与多个剩余开站批次相关联的多个远端射频单元集。例如，可以得到S2个剩余开站批次，S2＝向上取整(N-M1/M2)，将N-M1个待开站的远端射频单元120可以按照最大允许数量M2和S2个剩余开站批次进行划分，得到S2个远端射频单元集，其中每个远端射频单元集中的远端射频单元的数量不超过M2。
在框616处，基带单元110向第二远端射频单元集发送启动开站消息，第二远端射频单元集与经更新的开站配置数据中的第二开站批次相关联，第二开站批次位于第一开站批次之后。
由此，通过将基带单元所耦接的多个远端射频单元划分为多个开站批次，并在前一批次开站完成后再启动下一批次开站，能够降低基 带单元所耦接的多个远端射频单元的开站瞬时总功耗。此外，通过实时监测第一远端射频单元集的开站功耗集，并在开站功耗集中的最大开站功耗大于预设开站功耗的情况下更新开站配置数据，能够避免剩余开站批次发生开站瞬时总功耗超过当前站点可用功率的情况下，从而避免跳闸。
在一些实施例中，基带单元110如果确定最大开站功耗大于预设开站功耗，则基于最大开站功耗，更新预设开站功耗。例如，将预设开站功耗更新为最大开站功耗。由此，能够将开站过程中统计的最大开站功耗用于更新预设开站功耗，便于后续开站使用。
在一些实施例中，基带单元110还可以获取与多个远端射频单元集相关联的多个最大开站功耗。应当理解，与远端射频单元集相关联的最大开站功耗指的是远端射频单元集的开站功耗集中的最大开站功耗，也可以称为开站批次功耗峰值。对于多个开站批次的情况，存在多个开站批次功耗峰值，例如如果存在3个开站批次，则存在对应的3个开站批次功耗峰值。
基带单元110可以从多个最大开站功耗确定最大的第一最大开站功耗。也就是确定多个开站批次功耗峰值中最大的一个开站批次功耗峰值。例如存在3个开站批次以及对应的3个开站批次功耗峰值，则从这3个开站批次功耗峰值确定最大的一个开站批次功耗峰值。
基带单元110可以确定第一最大开站功耗是否小于预设开站功耗。基带单元110如果确定第一最大开站功耗小于预设开站功耗，则更新预设开站功耗。更新的预设开站功耗可以用于下次分批次开站。基带单元110如果确定第一最大开站功耗大于或等于预设开站功耗，则不更新预设开站功耗。
由此，能够确定多个开站批次的多个远端射频单元集中的第一最大开站功耗，并且在第一最大开站功耗小于预设开站功耗的情况下，更新预设开站功耗，从而使得预设开站功耗更真实反馈实际情况，便于下次自动分批次开站更准确划分。
此外，基带单元110还可以响应于确定多个远端射频单元开站完成，基于经更新的预设开站功耗、当前站点可用功率以及总数量，更 新经更新的开站配置数据。例如，基带单元110可以通过确定接收到来自多个远端射频单元120的多个开站完成消息，来确定多个远端射频单元开站完成。
具体来说，基带单元110可以基于经更新的预设开站功耗和当前站点可用功率，确定用于每个开站批次的远端射频单元的最大允许数量。例如，经更新的预设开站功耗为P2，当前站点可用功率为T，则用于每个开站批次的远端射频单元的最大允许数量M3＝向下取整(T/P2)。
随后，基带单元110可以基于所确定的最大允许数量和与基带单元110相耦接的远端射频单元的总数量，生成多个开站批次以及多个远端射频单元集。例如，与基带单元110相耦接的远端射频单元的总数量为N，则可以得到S3个开站批次，S3＝向上取整(N/M3)，将多个远端射频单元120可以按照最大允许数量M3和S3个开站批次进行划分，得到S3个远端射频单元集，其中每个远端射频单元集中的远端射频单元的数量不超过M3。
由此，能够在多批次的远端射频单元集开站完成后，将开站过程中统计的最大开站功耗更新的预设开站功耗用于再次更新开站配置数据，使得开站配置数据更加准确地实际开站情况，从而避免在下次开站过程中导致跳闸的情况。
