Description

无线设备、资源管理方法以及通信系统
本申请要求于2021年12月30日提交中国专利局、申请号为202111661748.2、发明名称为“无线设备、资源管理方法以及通信系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，尤其涉及无线设备、资源管理方法以及通信系统。
背景技术
共享网络，指多家运营商采用同一套基础设施或网络资源(例如，某一家运营商建设的基础设备或网络资源)与终端设备进行通信，以实现降低网络基础设施建设成本的目的。
目前，运营商之间共享网络的主要方式为接入网共享(radio access network sharing，RAN Sharing)。具体地，如图1A所示，由主运营商提供基站系统中的无线设备控制器和无线设备，其他运营商通过各自的核心网设备与主运营商的基站系统中的无线设备控制器连接。其他运营商需要借助主运营商连接的网管设备，才能实现对共享的无线设备中的资源的管理。
由于，基站系统中的无线设备控制器仅能够由主运营商的网管设备进行管理，而其他运营商没有对该基站系统的管理权限。当其他运营商需要执行资源申请、载波建立、网络监控、故障处理、配置变更等操作时，都需要依托于主运营商的网管设备进行相应的操作，即通过主运营商的网管设备向主运营商的无线设备控制器发送消息，再由该主运营商的无线设备控制器向无线设备发送消息以申请或管理无线资源。因此，传统技术中的接入网共享方式严重影响了其他运营商的无线设备控制器的资源申请、载波建立、网络监控、故障处理、配置变更等一些列操作的处理效率。
发明内容
本申请提供了一种无线设备、资源管理方法以及通信系统，用于实现多个无线设备控制器在共享同一无线设备中的物理资源的同时，独立地对无线设备中的物理资源进行管理。
第一方面，本申请提供了一种无线设备，该无线设备通过前传接口与至少两个无线设备控制器连接。该无线设备主要包括接口模块和处理模块。
其中，接口模块，用于获取来自第一无线设备控制器的载波建立请求，该第一无线设备控制器为与该无线设备连接的至少两个无线设备控制器中的一个无线设备控制器，该载波建立请求用于请求建立该第一无线设备控制器的第一载波。
此外，处理模块，用于根据该载波建立请求确定第一物理资源信息，并且，根据该第一物理资源信息和该无线设备中该第一无线设备控制器对应的物理资源确定是否建立该第一载波。其中，该第一物理资源信息用于指示建立该第一载波所需要的物理资源，该至少两个无线设备控制器对应该无线设备中的不同物理资源。
应注意，传统技术中的无线设备的接口模块仅与一个无线设备控制(即主运营商的无线设备控制器)连接，因此，传统技术中的无线设备中的接口模块无法获得来自其他无线设备 控制器的载波建立请求。
此外，本申请中，无线设备除了能够与至少两个无线设备控制器连接之外，该无线设备还能够获知每个无线设备控制器对应的物理资源，并且，该至少两个无线设备控制器对应该无线设备中的不同物理资源。因此，该无线设备能够在收到该载波建立请求之后，根据该第一无线设备控制器(发送给载波建立请求的无线设备控制器)对应的物理资源确定第一物理资源信息指示的资源是否足以建立第一载波，而不会利用其它无线设备控制器对应的物理资源。因此，能够实现前述多个无线设备控制器独立地对无线设备中的物理资源进行管理。此外，在实现多个无线设备控制器共享一个无线设备的同时，能够提升无线设备控制器对应无线设备进行管理的灵活性。
在一种可能的实施方式中，该无线设备还包括存储模块。该存储模块可以与前述处理模块耦合，也可以独立于前述处理模块。该存储模块用于存储第一资源表，该第一资源表包括该至少两个无线设备控制器中每个无线设备控制器对应的物理资源。
示例性的，该无线设备与第一无线设备控制器和第二无线设备控制器连接。其中，第一无线设备控制器为与无线设备连接的至少两个无线设备控制器中的一个无线设备控制器，第二无线设备控制器为与无线设备连接的至少两个无线设备控制器中的另一个无线设备控制器。此时，该存储模块内存储的第一资源表包括第一无线设备控制器对应的物理资源和第二无线设备控制器对应的物理资源。其中，第一无线设备控制器对应的物理资源包括频段资源、功率资源、通道资源、载波资源等多种物理资源，第二无线设备控制器对应的物理资源也包括频段资源、功率资源、通道资源、载波资源等多种物理资源。
可选的，该第一资源表还包括每个无线设备控制器允许使用的物理资源的种类，以及每种物理资源的资源量或者每种物理资源的资源属性。
应理解，前述第一资源表中的各个无线设备控制器对应的物理资源可以是人工预先分配的，也可以由无线设备动态分配的。示例性的，可以由人工将第一资源表输入至无线设备的存储模块中；也可以由人工将第一资源表输入至与前述无线设备连接的至少两个无线设备控制器中的某一个无线设备控制器中，然后，该无线设备控制器将第一资源表发送至无线设备，然后，该无线设备将前述第一资源表存储于存储模块中。本申请不对无线设备获得第一资源表的实施方式进行限定。应理解，无论采用前述任何一种实施方式，不同的无线设备控制器对应的物理资源是确定的，无线设备中的处理模块仅可以将第一无线设备控制器对应的物理资源分配给第一无线设备控制器使用。
传统技术中，由于是主运营商的无线设备控制器向无线设备申请资源，无线设备并不感知主运营商的无线设备控制器申请的物理资源是用于建立哪家运营商的载波。因此，传统技术中的无线设备中没有前述第一资源表。本申请在无线设备中存储了记录各个无线设备控制器的对应的物理资源的第一资源表，能够将无线设备中的物理资源划分给与无线设备连接的至少两个无线设备控制器，以使得无线设备在载波建立阶段使用每个无线设备控制器对应的物理资源，有利于保证无线设备中的资源分配不冲突。
在一种可能的实施方式中，该载波建立请求包括该第一无线设备控制器的标识，该第一无线设备控制器的标识用于指示申请该第一无线设备控制器对应的物理资源。该处理模块， 还用于根据该第一无线设备控制器的标识查询该第一资源表中该第一无线设备控制器对应的物理资源。
本实施方式中，提出处理模块能基于第一无线设备控制器的标识查询该第一资源表中该第一无线设备控制器对应的物理资源，有利于保证无线设备查询第一无线设备控制器对应的物理资源的准确性。
可选的，若第一资源表中不同的无线设备控制器对应的物理资源的信息存储于不同的存储位置，则该处理模块可以基于第一无线设备控制器的标识仅查询第一无线设备控制器对应的物理资源的存储页，而不用遍历存储整个第一资源表的存储位置。
在一种可能的实施方式中，该处理模块包括一个中心控制模块和至少两个业务处理模块，该至少两个无线设备控制器与该至少两个业务处理模块一一对应。
其中，中心控制模块，用于根据该载波建立请求中的该第一无线设备控制器的标识，从该至少两个业务处理模块中确定与该第一无线设备控制器对应的第一业务处理模块，并将该载波建立请求传输至该第一业务处理模块。

本实施方式中，将处理模块划分为两大类模块，即控制类模块(即中心控制模块)和业务类模块(即至少两个业务处理模块)。由于，前述至少两个业务处理模块中的各个业务处理模块是相互独立的，每个业务处理模块是与无线设备控制器对应的，因此，各个业务处理模块能够相互独立地为对应的无线设备控制器处理消息(例如，载波建立请求)。相比于仅有一个业务处理模块处理来自不同的无线设备控制器的消息的方案，不仅有利于提高业务处理的效率，还有利于在一个无线设备中实现业务处理多样化，还有利于实现各个业务处理模块进行相互独立的更新维护。此外，当与无线设备连接的多个无线设备控制器分别属于不同的运营商时，无线设备内部能够运行不同的运营商的业务处理模块(也可以理解为，业务处理软件)，有利于在一个无线设备中基于不同的业务处理模块生成不同的符合各个运营商的需求的载波。
在一种可能的实施方式中，该无线设备还包括载波建立模块。该中心控制模块，具体用于：当该第一物理资源信息指示的物理资源的资源量小于该第一无线设备控制器对应的物理资源的资源量时，确定允许建立该第一载波，并将该第一物理资源信息传输至该载波建立模块。该载波建立模块，用于采用该第一物理资源信息指示的物理资源建立该第一载波。

在一种可能的实施方式中，该无线设备还可以基于无线设备控制器的粒度查询前述至少两个无线设备控制器中的某一个无线设备控制器对应的物理资源的使用信息。其中，该查询过程涉及接口模块、中心控制模块以及第一业务处理模块(即需要查询的无线设备控制器对应的业务处理模块)。
具体地，该接口模块，还用于接收来自该第一无线设备控制器的资源查询消息，该资源查询消息用于查询该第一无线设备控制器对应的物理资源的使用信息，该资源查询消息包括该第一无线设备控制器的标识。然后，该中心控制模块，还用于根据该第一无线设备控制器的标识将该资源查询消息传输至与该第一无线设备控制器对应的该第一业务处理模块。然后，该第一业务处理模块，还用于查询该第一无线设备控制器对应的物理资源的使用信息。然后，该接口模块，还用于向该第一无线设备控制器发送该第一无线设备控制器对应的物理资源的使用信息。
本实施方式中，提出每个业务处理模块可以查询某一个无线设备控制器的物理资源的使用信息，并向该无线设备控制器反馈该无线设备控制器的物理资源的使用信息。有利于避免无线设备将无线设备控制器的物理资源的使用情况误报给其他的无线设备控制器，有利于提高无线设备查询每个无线设备控制器的物理资源的使用信息的准确度。
在一种可能的实施方式中，该无线设备还可以基于无线设备控制器的粒度反馈故障信息，即向与无线设备连接的至少两个无线设备控制器中的一部分无线设备控制器反馈故障信息。其中，该故障反馈过程涉及接口模块和中心控制模块。
其中，中心控制模块用于获取故障信息，该故障信息用于指示该无线设备中出现故障的物理资源。然后，该中心控制模块从该至少两个无线设备控制器中确定至少一个第二无线设备控制器，该第二无线设备控制器为使用该故障信息指示的物理资源的无线设备控制器。然后，控制该接口模块向该第二无线设备控制器发送该故障信息。
本实施方式中，提出该无线设备还可以基于无线设备控制器的粒度进行故障反馈。具体地，该无线设备能够确定故障的物理资源将影响哪些无线设备控制器，然后，该无线设备仅向受影响的无线设备控制器反馈故障信息，而不会向与该无线设备连接的全部无线设备控制器反馈故障信息。
在一种可能的实施方式中，该接口模块，还用于获取资源配置消息，该资源配置消息包括该第一资源表。
本实施方式中，由于，无线设备与无线设备控制器并不一定位于同一地理位置(例如，无线设备常常位于信号塔上，而无需设备控制器位于基站的机房中)，因此，将第一资源表通过与无线设备连接的某一个无线设备控制器发送给前述无线设备，有利于提高资源配置效率，避免人工上信号塔进行配置，有利于降低运维管理的复杂度。
第二方面，本申请提供了一种第一无线设备控制器，该第一无线设备控制器是与无线设备连接的至少两个无线设备控制器中的一个无线设备控制器，该第一无线设备控制器包括：处理模块和接口模块。

本实施例中，与无线设备连接的多个无线设备控制器中的任意一个无线设备控制器均能够向无线设备发送载波建立请求，以请求使用该无线设备中第一无线设备控制器对应的物理资源建立第一载波。因此，能够实现前述多个无线设备控制器独立地对无线设备中的物理资源进行管理。在实现多个无线设备控制器共享一个无线设备的同时，提升了无线设备控制器对应无线设备进行管理的灵活性。
第三方面，本申请提供了一种资源管理方法，该资源管理方法由与至少两个无线设备控制器连接的无线设备执行。在该方法中，无线设备可以获取来自第一无线设备控制器的载波建立请求，该第一无线设备控制器为与该无线设备连接的至少两个无线设备控制器中的一个无线设备控制器，该载波建立请求用于请求建立该第一无线设备控制器的第一载波。然后，该无线设备根据该载波建立请求确定第一物理资源信息，该第一物理资源信息用于指示建立该第一载波所需要的物理资源。然后，该无线设备根据该第一物理资源信息和该无线设备中该第一无线设备控制器对应的物理资源确定是否建立该第一载波，该至少两个无线设备控制器对应该无线设备中的不同物理资源。
本申请中，除了无线设备能够与至少两个无线设备控制器连接之外，该无线设备还能够获知每个无线设备控制器对应的物理资源，并且，该至少两个无线设备控制器对应该无线设备中的不同物理资源。因此，该无线设备能够在收到该载波建立请求之后，根据该第一无线设备控制器(发送给载波建立请求的无线设备控制器)对应的物理资源确定第一物理资源信息指示的资源是否足以建立第一载波，而不会利用其它无线设备控制器对应的物理资源。因此，能够实现前述多个无线设备控制器独立地对无线设备中的物理资源进行管理。在实现多个无线设备控制器共享一个无线设备的同时，提升了无线设备控制器对应无线设备进行管理的灵活性。

还应理解，当无线设备控制器与无线设备之间采用的通信协议不同时，即无线设备控制器与无线设备之间采用的前传接口不同时，无线设备控制器的称谓可能不同，无线设备的称谓也可能不同。示例性的，在通用公共无线接口(common public radio interface，CPRI)协议中，无线设备控制器被称为无线设备控制器(radio equipment control，REC)，无线设备被称为无线设备(radio equipment，RE)；在增强的通用公共无线接口(enhanced common public radio interface，eCPRI)协议中，无线设备控制器被称为eCPRI无线设备控制器(eCPRI radio equipment control，eREC)，无线设备被称为eCPRI无线设备(eCPRI radio equipment，eRE)。应理解，在其他的为基带单元和射频单元提供通信的协议中，该无线设备控制器还可以有其他的称谓。具体本申请不对无线设备控制器的具体实现形式和具体称谓进行限定，在后文以“无线设备控制器”这一称谓进行介绍。类似的，在其他的为基带单元和射频单元提供通信的协议中，该无线设备还可以有其他的称谓。具体本申请不对无线设备的具体实现形式和具体称谓进行限定，在后文以“无线设备”这一称谓进行介绍。
下面将结合图2A对无线设备的内部结构进行介绍。如图2A所示，为本申请提供的无线设备20的一种实施方式。该无线设备20包括接口模块201和处理模块202。可选的，该无线设备20还包括存储模块203和载波建立模块204。
其中，接口模块201，用于获取来自第一无线设备控制器的载波建立请求，该第一无线设备控制器为与该无线设备连接的至少两个无线设备控制器中的一个无线设备控制器。例如，在图2A中，无线设备20与无线设备控制器1、无线设备控制器2等n个无线设备控制器连接，其中，n为大于1的整数。此时，该第一无线设备控制器为图2A中的前述n个无线设备控制器中的某一个无线设备控制器。
可选的，前述至少两个无线设备控制器可以是属于不同运营商的无线设备控制器。例如，无线设备控制器1属于运营商1，无线设备控制器2属于运营商2，其中，运营商1和运营商2是不同的运营商。一般地，当两个无线设备控制器属于不同的运营商时，前述两个无线设备控制器的管理逻辑不同，能够使用的无线设备中的物理资源不同。
此外，前述载波建立请求用于请求建立该第一无线设备控制器的第一载波，也可以理解为，该载波建立请求用于向无线设备申请使用一部分物理资源，以使得该无线设备使用前述物理资源为前述第一无线设备控制器建立第一载波。当然，该载波建立请求中携带建立第一载波所需要的一些信息，后文将进行详细介绍。
此外，处理模块202，用于根据该载波建立请求确定第一物理资源信息，并且，根据该第一物理资源信息和该无线设备中该第一无线设备控制器对应的物理资源确定是否建立第一载波。
其中，该第一物理资源信息是处理模块202基于载波建立请求携带的内容确定的，该第一物理资源信息用于指示建立该第一载波所需要的物理资源。应理解，该第一物理资源信息可以指示一种物理资源，也可以指示多种物理资源。其中，物理资源包括但不限于频段资源、功率资源、通道资源、载波资源以及流数资源。因此，前述第一物理资源信息包括频段资源、功率资源、通道资源、载波资源以及流数资源中的至少一种资源的信息。
其中，频段资源指建立载波时使用的频段或频域范围。一般地，频段资源是与运营商相关的资源，每家运营商拥有固定的频段，不同的运营商允许使用的频段不同。例如，该频段资源为运营商的许可(license)频段，不同运营商的许可(license)频段不同。无线设备控制器仅允许使用该无线设备控制器所属的运营商的频段。例如，若1.8GHz 1890MHz～1895MHz属于运营商1，则运营商2的无线设备控制器便无法使用前述1.8GHz 1890MHz～1895MHz的频段资源，仅可以由运营商1的无线设备控制器申请使用前述1.8GHz 1890MHz～1895MHz的频段资源。此外，频段资源包括发送频率和接收频率。一般地，在频分双工(frequency-division duplex，FDD)模式下，发送频率与接收频率不同。例如，在1.8GHz中，可以设置1765MHz～1785MHz为发送频率(也可以被称为，上行频率)，设置1860MHz～1880MHz为接收频率(也可以被称为，下行频率)。又例如，在2.1GHz中，可以设置1920MHz～1960MHz为发送频率，设置2110MHz～2150MHz为接收频率。一般地，在时分双工(time-division duplex，TDD)模式下，发送频率与接收频率可以相同。例如，在3.5GHz中，可以设置3580MHz～3600MHz为发送频率和接收频段。
应理解，前述频段资源采用FDD模式或TDD模式与无线设备控制器需要建立的载波相关，本申请不对频段资源的双工模式进行限定。
此外，功率资源指建立的载波经过功率放大器进行放大的功率的倍数。一般地，使用不同频段资源的载波可以使用的功率资源是独立的。应理解，前述功率资源是频段级的，无线设备将功率资源给同一频段下的所有载波共享。例如，1.8GHz的所有载波共享使用20W的功率资源；2.1GHz的所有载波共享使用40W的功率资源。因此，若其中一个频段下某个载波的占用较多的功率资源(例如，发射功率较大)，则该频段下的其它载波能够占用的功率资源便较少(例如，发射功率较小)。应理解，载波的发射功率越大，则该载波的发射距离越远，该载波能提供服务的范围就越广。但是，发射功率也并非越大越好。因为终端设备的发射功率是一定的，若发射距离太远，则终端设备可能仅能够收到来自无线设备的信号，却收不到终端设备发送的信号。通常情况下，运营商会按照频谱带宽均分功率，以保证覆盖相同。例如，若2.1GHz的功率是20W，并且，2.1GHz上有两个载波，带宽分别是20M和5M，此时，20M的载波占用的功率资源为16W，5M的载波占用的功率资源为4W。
此外，通道资源指占用的射频链路通道的数量。一般地，通道资源与频段相关。例如，无线设备中2.1GHz频段的通道资源为2T，1.8GHz频段的通道资源为3T，表示无线设备在建立频段为2.1GHz的载波时最多可以使用两个通道，在建立频段为1.8GHz的载波时最多可以使用三个通道。在一些可能的实施方式中，通道资源还能够指示占用的通道的标识或编号，即指示占用哪几个通道。例如，若无线设备中2.1GHz频段的通道资源为T1和T2，表示该无线设备在建立2.1GHz频段的载波时可以使用编号为“T1”和“T2”这两个通道。
应注意，由于，无线设备中的各个通道的发射器件是独立的，因此，无线设备中的各个通道的功率也是相互独立的。若某个通道给多个无线设备控制器共享，则通道的功率也需要给前述多个无线设备控制器共享。因此，在实际应用中，一般将通道资源与功率资源结合来考虑共享。在一种可能的实现中，将通道资源和功率资源合并为通道功率资源。例如，A通道分配给1.8GHz的功率为20W，而分配给2.1GHz的功率为40W。
此外，载波资源指无线设备能够处理的载波数量。该载波资源主要是中频数字资源，用于对每个载波进行变频/削波/预失真等处理。示例性的，以无线设备的最大载波资源是4(即该无线设备最多能够处理4个载波)为例。假设一个无线设备控制器对应的频段资源为2.1GHz 2130～2150 20M和1.8GHz 1830～1850 20M，若该无线设备控制器选择建立1个2.1GHz 20M载波和1个1.8GHz 20M载波，则该无线设备需要消耗的载波资源为2；若该无线设备控制器选择建立2个2.1GHz 10M载波和2个1.8GHz 10M载波，则该无线设备需要消耗的载波资源为4。当多个无线设备控制器共享载波资源的时候，某一个无线设备控制器用的越多，其它的无线设备控制器可用的就越少，甚至有可能导致其它无线设备控制器在有频谱/功率等资源的情况下，因为无载波资源而无法成功建立载波。
此外，流数资源指无线设备同一时刻能够处理的终端用户业务流的数量。该流数资源包括上行流数资源和下行流数资源。其中，上行流数资源指无线设备同一时刻能够处理的终端用户的上行业务流的数量。下行流数资源指无线设备同一时刻能够处理的终端用户的下行业务流的数量。
应理解，该流数资源是基带处理资源的一种，当该无线设备具备基带处理功能时，例如，该无线设备控制器为AAU时，该无线设备才能够向多个无线设备控制器共享流数资源。一般地，无线设备控制器分得的流数资源越多，说明该无线设备能够为该无线设备控制器处理更多的终端用户的数据，因此能够给用户提供更好的通信体验。
应理解，前述物理资源仅仅是为了便于读者理解而列举的示例，在实际应用中，无线设备还可能为前述至少两个无线设备控制器提供其他种类的物理资源，本申请不对无线设备提供的物理资源的具体进行限定。
具体地，前述第一物理资源信息不仅可以指示建立该第一载波所需要的物理资源的种类，还可以指示每种物理资源的资源量。例如，第一物理资源信息不仅可以指示建立第一载波需要通道资源，还可以明确指出建立第一载波需要两个通道的通道资源，即通道资源的资源量为两个通道。又例如，第一物理资源信息不仅可以指示建立第一载波需要功率资源，还可以明确指出建立第一载波需要的功率资源为20W，即第一载波的发射功率为20W。又例如，当将通道资源和功率资源合并为通道功率资源时，第一物理资源信息可以指示建立第一载波需要的通道功率资源为A通道20W，即第一载波的使用A通道，并且，第一载波的发射功率为20W。
应理解，前述第一物理资源信息不仅可以指示建立该第一载波所需要的物理资源的种类，以及每种物理资源的资源量，还可以指示每种物理资源的属性。例如，第一物理资源信息可以指示建立第一载波需要种类为频段资源的物理资源，该频段资源的资源量为5MHz，该频段资源的属性为1.8GHz 1890MHz～1895MHz。又例如，第一物理资源信息可以指示建立第一载波需要种类为通道资源的物理资源，该频段资源的资源量为2个通道，该频段资源的属性为通道编号为T1的射频通道和通道编号为T2的射频通道。
应理解，不同的无线设备控制器能够使用的位于无线设备中的物理资源是不同的，即无线设备20中的物理资源被划分给前述至少两个无线设备控制器，并且，前述至少两个无线设备控制器对应该无线设备20中的不同物理资源。也就是说，无线设备20中的物理资源划分给哪些无线设备控制器，每个无线设备控制器允许使用哪些物理资源等信息是确定的。因此，当该处理模块202基于第一物理资源信息获知该第一无线设备控制器在申请建立第一载波时需要使用哪些物理资源时，该处理模块202需要确定第一物理资源信息指示的物理资源与该无线设备中该第一无线设备控制器对应的物理资源之间的关系，以确定是否建立该第一载波。
具体地，该处理模块202需要确定第一物理资源信息指示的物理资源是否属于该第一无线设备控制器对应的物理资源。若第一物理资源信息指示的物理资源属于该第一无线设备控制器对应的物理资源，则该处理模块202确定允许建立第一载波；若第一物理资源信息指示的物理资源不属于该第一无线设备控制器对应的物理资源，则该处理模块202确定不允许建立第一载波。
也可以理解为，处理模块202基于第一物理资源信息指示的物理资源的资源量与该第一无线设备控制器对应的物理资源的资源量的关系确定是否允许建立第一载波。示例性的，若第一物理资源信息指示的物理资源的资源量小于该第一无线设备控制器对应的物理资源的资源量，则处理模块202确定允许建立该第一载波。然后，该处理模块202将该第一物理资源信息传输至该载波建立模块204，该载波建立模块204采用该第一物理资源信息指示的物理资源建 立该第一载波。若第一物理资源信息指示的物理资源的资源量大于该第一无线设备控制器对应的物理资源的资源量，则处理模块202确定不允许建立第一载波，并且，控制该接口模块201向该第一无线设备控制器发送载波建立响应，该载波建立响应用于指示该第一载波建立失败。
本实施例中，由于无线设备20能够与多个无线设备控制器连接，并且，该无线设备20能够从前述多个无线设备控制器中的某一个无线设备控制器获取载波建立请求，并基于该载波建立请求确定用于建立载波的物理资源，进而根据前述物理资源和所述无线设备中前述无线设备控制器对应的物理资源确定是否建立载波。因此，能够实现多个无线设备控制器共享一个无线设备，提升了无线设备控制器对应无线设备进行管理的灵活性。
其中，该无线设备20还包括存储模块203。该存储模块203可以与处理模块202耦合，也可以独立于前述处理模块202。该存储模块203用于存储第一资源表，该第一资源表包括与该无线设备20连接的至少两个无线设备控制器中每个无线设备控制器对应的物理资源。
可选的，该第一资源表还包括每个无线设备控制器允许使用的物理资源的种类，以及每种物理资源的资源量或者每种物理资源的资源属性。
为便于理解，以无线设备20与无线设备控制器1和无线设备控制器2连接为例，此时，该无线设备20的存储模块203内存储的第一资源表包括无线设备控制器1对应的物理资源和无线设备控制器2对应的物理资源。其中，无线设备控制器1对应的物理资源包括频段资源、功率资源、通道资源、载波资源等多种物理资源，无线设备控制器2对应的物理资源也包括频段资源、功率资源、通道资源、载波资源等多种物理资源。此时，该无线设备20中的第一资源表可以如下表1-1所示：
表1-1
Figure PCTCN2022136770-appb-000001
在表1-1所示示例中，无线设备20将物理资源划分给无线设备控制器1和无线设备控制器2，其中，无线设备控制器1和无线设备控制器2对应的物理资源不同。根据表1-1中的载波资源可知，无线设备最多允许无线设备控制器1建立4个载波，最多允许无线设备控制器2建立2 个载波。对于无线设备控制器1，该无线设备最多处理6条上行业务流和8条下行业务流，最多处理2条上行业务流和8条下行业务流。
例如，无线设备控制器1允许使用四种频段的频段资源，分别为发送频段“1.8GHz 1765MHz～1785MHz”、接收频段“1.8GHz 1860MHz～1880MHz”、发送频段“2.1GHz 1920MHz～1960MHz”和接收频段“2.1GHz 2110MHz～2150MHz”；而无线设备控制器2允许使用两种频段的频段资源，即发送频段“1.8GHz 1745MHz～1765MHz”和接收频段“1.8GHz 1840MHz～1860MHz”。
又例如，若无线设备控制器1采用2.1GHz的频段生成载波，则该无线设备20允许无线设备控制器1使用的功能是40W；若无线设备控制器1采用1.8GHz的频段生成载波，则该无线设备20允许无线设备控制器1使用的功能是20W。
又例如，若无线设备控制器1采用2.1GHz的频段生成载波，则该无线设备20允许无线设备控制器1使用通道1(即表1-1中的标识为“T1”的通道)和通道2(即表1-1中的标识为“T2”的通道)共两个通道的通道资源；若无线设备控制器1采用1.8GHz的频段生成载波，则该无线设备20允许无线设备控制器1使用另外两个通道的通道资源，即通道5(即表1-1中的标识为“T5”的通道)和通道6(即表1-1中的标识为“T6”的通道)。
在另一种可能的示例中，若将功率资源和通道资源结合，此时，无线设备控制器1对应的物理资源包括频段资源、通道功率资源、载波资源等多种物理资源，无线设备控制器2对应的物理资源也包括频段资源、通道功率资源、载波资源等多种物理资源。此时，该无线设备20中的第一资源表可以如下表1-2所示：
表1-2
Figure PCTCN2022136770-appb-000002
在表1-2所示示例中，无线设备20将物理资源划分给无线设备控制器1和无线设备控制器2，其中，无线设备控制器1和无线设备控制器2对应的物理资源不同。例如，若无线设备控制器1采用2.1GHz的频段生成载波，则该无线设备20允许无线设备控制器1使用A通道和B通道共两种通道，其中，A通道和B通道的最大功率均为40W；若无线设备控制器1采用1.8GHz的频段生成载波，则该无线设备20允许无线设备控制器1使用A通道和B通道共两种通道，其中，A 通道和B通道的最大功率均为20W。此外，表1-2中其他物理资源的解释请参阅前文表1-1对应的相关介绍，此处不予赘述。
应理解，前述表1-1所示示例和表1-2所示示例仅为本申请提出的第一资源表在FDD模式下的两种可能的示例，在实际应用中，第一资源表中的频段资源还可以采用TDD模式，因此，还可能存在其他的关于第一资源表的示例，具体本申请不再一一举例。
应理解，前述第一资源表中的各个无线设备控制器对应的物理资源可以是人工预先分配的，也可以由无线设备20动态分配的。示例性的，可以由人工将第一资源表输入至无线设备20的存储模块203中；也可以由人工将第一资源表输入至与前述无线设备20连接的至少两个无线设备控制器中的某一个无线设备控制器中，然后，该无线设备控制器将第一资源表发送至无线设备20，然后，该无线设备20将前述第一资源表存储于存储模块203中。本申请不对无线设备20获得第一资源表的实施方式进行限定。应理解，无论采用前述任何一种实施方式，不同的无线设备控制器对应的物理资源是确定的，无线设备20中的处理模块202仅可以将第一无线设备控制器对应的物理资源分配给第一无线设备控制器使用。
传统技术中，由于是主运营商的无线设备控制器向无线设备申请资源，无线设备并不感知主运营商的无线设备控制器申请的物理资源是用于建立哪家运营商的载波。因此，传统技术中的无线设备中没有前述第一资源表。本申请在无线设备20中存储了记录各个无线设备控制器的对应的物理资源的第一资源表，能够将无线设备20中的物理资源划分给与无线设备20连接的至少两个无线设备控制器，以使得无线设备20在载波建立阶段使用每个无线设备控制器对应的物理资源，有利于保证无线设备20中的资源分配不冲突。
在一种可能的实施方式中，前述载波建立请求包括该第一无线设备控制器的标识，该第一无线设备控制器的标识用于指示申请该第一无线设备控制器对应的物理资源。由于，该处理模块202能够获知第一资源表的存储位置，因此，该处理模块202，还用于根据该第一无线设备控制器的标识查询该第一资源表中该第一无线设备控制器对应的物理资源。
可选的，若第一资源表中不同的无线设备控制器对应的物理资源的信息存储于不同的存储位置，则该处理模块202可以基于第一无线设备控制器的标识仅查询第一无线设备控制器对应的物理资源的存储页，而不用遍历存储整个第一资源表的存储位置。
可选的，该处理模块202还可以基于第一无线设备控制器的标识对应载波建立请求进行合法性校验。例如，该处理模块202基于第一无线设备控制器的标识确定该载波建立请求是否来自该第一无线设备控制器的标识指示的无线设备控制器。有利于避免其他的无线设备控制器恶意伪造第一无线设备控制器的载波建立请求，而影响第一无线设备控制器的载波建立。
本实施方式中，由于传统技术中的无线设备中并没有第一资源表，因此，传统技术中的无线设备无法基于某个无线设备控制器的标识查询该无线设备控制器对应的物理资源。
上面介绍了无线设备20的主要结构，下面将结合图2B对无线设备20内部的各个功能模块进行进一步介绍。如图2B所示，为本申请提供的无线设备20的另一种实施方式。该无线设备20包括接口模块201、处理模块202、存储模块203以及载波建立模块204。
其中，处理模块202包括一个中心控制模块2021和至少两个业务处理模块2022，该至少两个无线设备控制器与该至少两个业务处理模块2022一一对应，每个业务处理模块2022仅处理来自对应的无线设备控制器的消息(例如，载波建立请求)。例如，图2B中的中心控制模块 2021与业务处理模块1、业务处理模块2等n个业务处理模块2022连接，其中，n为大于1的整数。若无线设备控制器1与业务处理模块1对应，则业务处理模块1仅可以处理来自无线设备控制器1的消息；若无线设备控制器2与业务处理模块2对应，则业务处理模块2仅可以处理来自无线设备控制器2的消息。以此类推，此处不予赘述。
应理解，前述第一无线设备控制器对应第一业务处理模块，第一业务处理模块并没有在图2B中明确指出。若第一无线设备控制器的标识指示的是无线设备控制器1，则该第一业务处理模块为图2B中的业务处理模块1。以此类推，此处不予赘述。
具体地，该处理模块202中的中心控制模块2021，用于根据该载波建立请求中的第一无线设备控制器的标识，从该至少两个业务处理模块2022中确定与该第一无线设备控制器对应的第一业务处理模块，并将该载波建立请求传输至该第一业务处理模块。该第一业务处理模块，用于根据该载波建立请求确定该第一物理资源信息，并将该第一物理资源信息传输至该中心控制模块2021；该中心控制模块2021，用于根据该第一物理资源信息和该第一无线设备控制器对应的物理资源确定是否建立该第一载波。
其中，业务处理模块用于处理对应的无线设备控制器相关的业务。以第一业务处理模块为例，第一无线设备控制器对应的第一业务处理模块用于根据来自第一无线设备控制器的载波建立请求确定第一物理资源信息。该第一业务处理模块在确定第一物理资源信息时，可以有如下两种实现方式：
在一种实现中，载波建立请求直接携带的是第一物理资源信息，则该第一业务处理模块直接从载波建立请求中获取前述第一物理资源信息。
在另一种实现中，载波建立请求携带的是第一载波参数，该第一载波参数用于指示该第一载波的特征。此时，该第一业务处理模块具体用于根据该第一载波参数和与该第一无线设备控制器对应的预设规则生成该第一物理资源信息，该至少两个无线设备控制器中不同的无线设备控制器对应的预设规则不同，该第一物理资源信息包括频段资源、功率资源、通道资源、载波资源以及流数资源中的至少一种资源的信息。
其中，预设规则可以理解为业务处理模块的处理逻辑，不同的业务处理模块对应不同的无线设备控制器。若不同的业务处理模块有着不同的业务处理逻辑，则不同的业务处理模块对应不同的预设规则。在本实施例中，可以将预设规则理解为将第一载波参数转换为第一无线资源信息的规则。若将第一载波参数输入至其他的无线设备控制器对应的业务处理模块(例如，第二无线设备控制器对应的第二业务处理模块)，则该第二业务处理模块可能无法识别前述第一载波参数，也可以无法将前述第一载波参数转换为第一物理资源信息。
示例性的，若运营商1通过网管设备在第一无线设备控制器上配置了一个20M带宽的FDD LTE的2T2R载波，使用发送频率2110MHz～2130MHz，接收频率1920MHz～1940MHz。此时，该载波建立请求中的第一载波参数为：“带宽＝20M，双工模式＝FDD，制式＝LTE，发送模式＝2T，接收模式＝2R，频段＝2.1GHz”。然后，该第一业务处理模块将基于前述第一载波参数和第一业务处理模块对应的预设规则，确定建立该第一载波所需要的物理资源的信息(即第一物理资源信息)包括：频段资源为“2.1GHz接收频率1920MHz～1940MHz，发送频率2110MHz～2130MHz”，功率资源为“2.1GHz 20W/每通道”，通道资源为“2.1GHz 2T”，上行流数资源为“4流”，下行流数资源为“4流”。
其中，中心控制模块2021在确定是否建立第一载波时，可以有如下两种实现方式：
在一种实现中，当该第一物理资源信息指示的物理资源的资源量小于该第一无线设备控制器对应的物理资源的资源量时，该中心控制模块2022确定允许建立该第一载波，并将该第一物理资源信息传输至该载波建立模块204。然后，该载波建立模块204，用于采用该第一物理资源信息指示的物理资源建立该第一载波。其中，载波建立模块204包括数字处理模块2041和模拟处理模块2042。其中，数字处理模块2041包括上变频器、下变频器以及数模转换器等具有数字信号处理功能的电路或器件。模拟处理模块2042包括中频放大器、滤波器、混频器、功率放大器等具有模拟信号处理功能的电路或器件。
可选的，当该中心控制模块2022确定允许基于该第一物理资源信息建立该第一载波之后，该中心控制模块2022将根据该第一物理资源信息指示的物理资源的资源量更新该第一资源表中该第一无线设备控制器对应的物理资源的资源量。示例性的，该中心控制模块2022将第一资源表中第一无线设备控制器对应的物理资源的资源量减去第一物理资源信息指示的物理资源的资源量，得到更新后的第一无线设备控制器对应的物理资源的资源量。例如，该第一物理资源信息指示的物理资源包括：频段资源“2.1GHz 1920MHz～1940MHz/2110MHz～2130MHz”和通道功率资源“2.1GHz 20W”，原本第一资源表中记录的该第一无线设备控制器对应的物理资源包括：频段资源“2.1GHz 1920MHz～1960MHz/2110MHz～2150MHz”和通道功率资源“2.1GHz 40W”，载波资源“4”，则更新之后，该第一资源表中记录的第一无线设备控制器对应的物理资源包括：频段资源“2.1GHz 1940MHz～1960MHz/2130MHz～2150MHz”和通道功率资源“2.1GHz 20W”，载波资源“3”。可选的，该中心控制模块2022还将在存储模块203中存储第一物理资源信息，以记录建立第一载波所使用的物理资源。例如，载波建立模块204为了建立第一载波采用了的哪些物理资源，每种物理资源使用了多少资源量。
在另一种实现中，当该第一物理资源信息指示的物理资源的资源量大于该第一无线设备控制器对应的物理资源的资源量时，该中心控制模块2022向该第一业务处理模块发送第一通知消息，该第一通知消息用于指示该第一无线设备控制器对应的物理资源不足以建立该第一载波。该第一业务处理模块控制该接口模块201向该第一无线设备控制器发送载波建立响应，该载波建立响应用于指示该第一载波建立失败。
本实施方式中，将处理模块202划分为两大类模块，即控制类模块(即中心控制模块2021)和业务类模块(即至少两个业务处理模块2022)。由于，前述至少两个业务处理模块中的各个业务处理模块是相互独立的，每个业务处理模块是与无线设备控制器对应的，因此，各个业务处理模块能够相互独立地为对应的无线设备控制器处理消息(例如，载波建立请求)。相比于仅有一个业务处理模块处理来自不同的无线设备控制器的消息的方案，不仅有利于提高业务处理的效率，还有利于在一个无线设备中实现业务处理多样化，还有利于实现各个业务处理模块进行相互独立的更新维护。此外，当与无线设备20连接的多个无线设备控制器分别属于不同的运营商时，无线设备20内部能够运行不同的运营商的业务处理模块(也可以理解为，业务处理软件)，有利于在一个无线设备中基于不同的业务处理模块生成不同的符合各个运营商的需求的载波。
进一步地，在一种可选的实施方式中，该接口模块201，还用于获取资源配置消息，该 资源配置消息包括该第一资源表。本实施方式中，由于，无线设备与无线设备控制器并不一定位于同一地理位置(例如，无线设备常常位于信号塔上，而无需设备控制器位于基站的机房中)，因此，将第一资源表通过与无线设备20连接的某一个无线设备控制器发送给前述无线设备20，有利于提高资源配置效率，避免人工上信号塔进行配置，有利于降低运维管理的复杂度。
此外，在一种可选的实施方式中，该接口模块201，还用于接收来自该第一无线设备控制器的资源查询消息，该资源查询消息用于查询该第一无线设备控制器对应的物理资源的使用信息。其中，该资源查询消息包括该第一无线设备控制器的标识。无线设备20能够基于查询消息中的第一无线设备控制器的标识确定是查询第一无线设备控制器的资源使用情况，而不是查询其他无线设备控制器的物理资源的使用信息。相应的，该无线设备20仅向第一无线设备控制器反馈该第一无线设备控制器的物理资源的使用信息。
具体地，该中心控制模块2021根据该第一无线设备控制器的标识将该资源查询消息传输至与该第一无线设备控制器对应的该第一业务处理模块。该第一业务处理模块查询该第一无线设备控制器对应的物理资源的使用信息。该接口模块201向该第一无线设备控制器发送该第一无线设备控制器对应的物理资源的使用信息。
本实施方式中，提出每个业务处理模块可以查询某一个无线设备控制器的物理资源的使用信息，并向该无线设备控制器反馈该无线设备控制器的物理资源的使用信息。有利于避免无线设备20将无线设备控制器的物理资源的使用情况误报给该无线设备控制器。
此外，在一种可选的实施方式中，该中心控制模块2021，还用于获取故障信息，该故障信息用于指示该无线设备20中出现故障的物理资源。然后，该中心控制模块2021从该至少两个无线设备控制器中确定至少一个第二无线设备控制器，该第二无线设备控制器为使用该故障信息指示的物理资源的无线设备控制器。然后，控制该接口模块201向该第二无线设备控制器发送该故障信息。

具体地，当该通信装置30的处理器301用于获取来自第一无线设备控制器的载波建立请求，该第一无线设备控制器为与该无线设备连接的至少两个无线设备控制器中的一个无线设备控制器，该载波建立请求用于请求建立该第一无线设备控制器的第一载波；该处理器301还用于根据该载波建立请求确定第一物理资源信息，该第一物理资源信息用于指示建立该第一载波所需要的物理资源；该处理器301还用于根据该第一物理资源信息和该无线设备中该第一无线设备控制器对应的物理资源确定是否建立该第一载波，该至少两个无线设备控制器对应该无线设备中的不同物理资源。
本实施例中，通信装置30不仅能够与至少两个无线设备控制器连接，该通信装置30还能够获知每个无线设备控制器对应的物理资源，并且，该至少两个无线设备控制器对应该无线设备中的不同物理资源。因此，该通信装置30能够在收到该载波建立请求之后，根据该第一无线设备控制器(发送给载波建立请求的无线设备控制器)对应的物理资源确定第一物理资源信息指示的资源是否足以建立第一载波，而不会利用其它无线设备控制器对应的物理资源。因此，能够实现前述多个无线设备控制器独立地对通信装置30中的物理资源进行管理。在实现多个无线设备控制器共享一个通信装置30的同时，提升了无线设备控制器对应通信装置30进行管理的灵活性。
在一种可能的实施方式中，该通信装置30存储有存储第一资源表，该第一资源表包括该至少两个无线设备控制器中每个无线设备控制器对应的物理资源。可选的，该第一资源表还包括每个无线设备控制器允许使用的物理资源的种类，以及每种物理资源的资源量或者每种物理资源的资源属性。

传统技术中，由于是主运营商的无线设备控制器向无线设备申请资源，无线设备并不感知主运营商的无线设备控制器申请的物理资源是用于建立哪家运营商的载波。因此，传统技术中的无线设备中没有前述第一资源表。本申请在无线设备中存储了记录各个无线设备控制器的对应的物理资源的第一资源表，能够将无线设备中的物理资源划分给与无线设备连接的至少两个无线设备控制器，以使得无线设备在载波建立阶段使用每个无线设备控制器对应的物理资源，有利于保证无线设备中的资源分配不冲突。

本实施例中，与无线设备连接的多个无线设备控制器中的任意一个无线设备控制器均能够向无线设备发送载波建立请求，以请求使用该无线设备中第一无线设备控制器对应的物理资源建立第一载波。因此，能够实现前述多个无线设备控制器独立地对无线设备中的物理资源进行管理。在实现多个无线设备控制器共享一个无线设备的同时，提升了无线设备控制器对应无线设备进行管理的灵活性。
下面将结合图6对本申请提出的资源管理方法的主要流程进行介绍。其中，无线设备控制器和无线设备将执行如下步骤：
步骤601，第一无线设备控制器向无线设备发送载波建立请求；相应的，无线设备获取来自第一无线设备控制器的载波建立请求。
其中，该第一无线设备控制器为与该无线设备连接的至少两个无线设备控制器中的一个无线设备控制器。具体地，该第一无线设备控制器与无线设备的连接方式可以参阅前文图2A或图2B对应的相关介绍，此处不予赘述。
此外，前述载波建立请求用于请求建立该第一无线设备控制器的第一载波，也可以理解为，该载波建立请求用于向无线设备申请使用一部分物理资源，以使得该无线设备使用前述物理资源为前述第一无线设备控制器建立第一载波。
其中，物理资源包括但不限于频段资源、功率资源、通道资源、载波资源以及流数资源。
下面分别对各种物理资源进行介绍：
其中，该第一物理资源信息基于载波建立请求携带的内容确定的，该第一物理资源信息用于指示建立该第一载波所需要的物理资源。应理解，该第一物理资源信息可以指示一种物理资源，也可以指示多种物理资源。其中，物理资源包括但不限于频段资源、功率资源、通道资源、载波资源以及流数资源。因此，前述第一物理资源信息包括频段资源、功率资源、通道资源、载波资源以及流数资源中的至少一种资源的信息。
其中，频段资源指建立载波时使用的频段或频域范围。一般地，频段资源是与运营商相关的资源，每家运营商拥有固定的频段，不同的运营商允许使用的频段不同。例如，该频段资源为运营商的许可(license)频段，不同运营商的许可(license)频段不同。无线设备控制器仅允许使用该无线设备控制器所属的运营商的频段。例如，若1.8GHz 1890MHz～1895MHz属于运营商1，则运营商2的无线设备控制器便无法使用前述1.8GHz 1890MHz～1895MHz的频段资源，仅可以由运营商1的无线设备控制器申请使用前述1.8GHz 1890MHz～1895MHz的频段资源。此外，频段资源包括发送频率和接收频率。一般地，在频分双工(frequency-division duplex，FDD)模式下，发送频率与接收频率不同。例如，在1.8GHz中，可以设置1765MHz～1785MHz为发送频率(也可以被称为，上行频率)，设置1860MHz～1880MHz为接收频率(也可以被称为，下行频率)。又例如，在2.1GHz中，可以设置1920MHz～1960MHz为发送频率，设置2110MHz～2150MHz为接收频率。一般地，在时分双工(time-division duplex，TDD)模式下，发送频率与接收频率可以相同。例如，在3.5GHz中，可以设置3580MHz～3600MHz为发送频率和接收频段。
应理解，前述频段资源采用FDD模式或TDD模式与无线设备控制器需要建立的载波相关，本申请不对频段资源的双工模式进行限定。
此外，功率资源指建立的载波经过功率放大器进行放大的功率的倍数。一般地，使用不同频段资源的载波可以使用的功率资源是独立的。应理解，前述功率资源是频段级的，无线设备将功率资源给同一频段下的所有载波共享。例如，1.8GHz的所有载波共享使用20W的功率资源；2.1GHz的所有载波共享使用40W的功率资源。因此，若其中一个频段下某个载波的占用较多的功率资源(例如，发射功率较大)，则该频段下的其它载波能够占用的功率资源 便较少(例如，发射功率较小)。应理解，载波的发射功率越大，则该载波的发射距离越远，该载波能提供服务的范围就越广。但是，发射功率也并非越大越好。因为终端设备的发射功率是一定的，若发射距离太远，则终端设备可能仅能够收到来自无线设备的信号，却收不到终端设备发送的信号。通常情况下，运营商会按照频谱带宽均分功率，以保证覆盖相同。例如，若2.1GHz的功率是20W，并且，2.1GHz上有两个载波，带宽分别是20M和5M，此时，20M的载波占用的功率资源为16W，5M的载波占用的功率资源为4W。
此外，通道资源指占用的射频链路通道的数量。一般地，通道资源与频段相关。例如，无线设备中2.1GHz频段的通道资源为2T，1.8GHz频段的通道资源为3T，表示无线设备在建立频段为2.1GHz的载波时最多可以使用两个通道，在建立频段为1.8GHz的载波时最多可以使用三个通道。在一些可能的实施方式中，通道资源还能够指示占用的通道的标识或编号，即指示占用哪几个通道。例如，若无线设备中2.1GHz频段的通道资源为T1和T2，表示该无线设备在建立2.1GHz频段的载波时可以使用编号为“T1”和“T2”这两个通道。
应注意，由于，无线设备中的各个通道的发射器件是独立的，因此，无线设备中的各个通道的功率也是相互独立的。若某个通道给多个无线设备控制器共享，则通道的功率也需要给前述多个无线设备控制器共享。因此，在实际应用中，一般将通道资源与功率资源结合来考虑共享。在一种可能的实现中，将通道资源和功率资源合并为通道功率资源。例如，A通道分配给1.8GHz的功率为20W，而分配给2.1GHz的功率为40W。
此外，载波资源指无线设备能够处理的载波数量。该载波资源主要是中频数字资源，用于对每个载波进行变频/削波/预失真等处理。示例性的，以无线设备的最大载波资源是4(即该无线设备最多能够处理4个载波)为例。假设一个无线设备控制器对应的频段资源为2.1GHz 2130～2150 20M和1.8GHz 1830～1850 20M，若该无线设备控制器选择建立1个2.1GHz 20M载波和1个1.8GHz 20M载波，则该无线设备需要消耗的载波资源为2；若该无线设备控制器选择建立2个2.1GHz 10M载波和2个1.8GHz 10M载波，则该无线设备需要消耗的载波资源为4。当多个无线设备控制器共享载波资源的时候，某一个无线设备控制器用的越多，其它的无线设备控制器可用的就越少，甚至有可能导致其它无线设备控制器在有频谱/功率等资源的情况下，因为无载波资源而无法成功建立载波。
此外，流数资源指无线设备同一时刻能够处理的终端用户业务流的数量。该流数资源包括上行流数资源和下行流数资源。其中，上行流数资源指无线设备同一时刻能够处理的终端用户的上行业务流的数量。下行流数资源指无线设备同一时刻能够处理的终端用户的下行业务流的数量。
应理解，该流数资源是基带处理资源的一种，当该无线设备具备基带处理功能时，例如，该无线设备控制器为AAU时，该无线设备才能够向多个无线设备控制器共享流数资源。一般地，无线设备控制器分得的流数资源越多，说明该无线设备能够为该无线设备控制器处理更多的终端用户的数据，因此能够给用户提供更好的通信体验。
应理解，前述物理资源仅仅是为了便于读者理解而列举的示例，在实际应用中，无线设备还可能为前述至少两个无线设备控制器提供其他种类的物理资源，本申请不对无线设备提供的物理资源的具体进行限定。
此外，关于频段资源、功率资源、通道资源、载波资源以及流数资源的示例请参阅前文图2A对应实施例的相关介绍，此处不予赘述。
该载波建立请求包括该第一无线设备控制器的标识，该第一无线设备控制器的标识用于指示申请该第一无线设备控制器对应的物理资源。
可选的，若第一资源表中不同的无线设备控制器对应的物理资源的信息存储于不同的存储位置，则无线设备可以基于第一无线设备控制器的标识仅查询存储模块中第一无线设备控制器对应的物理资源的存储页，而不用遍历存储整个第一资源表的存储位置。
可选的，该无线设备还可以基于第一无线设备控制器的标识对应载波建立请求进行合法性校验。例如，该无线设备基于第一无线设备控制器的标识确定该载波建立请求是否来自该第一无线设备控制器的标识指示的无线设备控制器。有利于避免其他的无线设备控制器恶意伪造第一无线设备控制器的载波建立请求，而影响第一无线设备控制器的载波建立。
此外，该载波建立请求还携带建立第一载波所需要的一些信息。
在一种可能的实施方式中，该载波建立请求还包括第一载波参数，该第一载波参数用于指示该第一载波的特征。
示例性的，若运营商1通过网管设备在第一无线设备控制器上配置了一个20M带宽的FDD LTE的2T2R载波，使用发送频率2110MHz～2130MHz，接收频率1920MHz～1940MHz。此时，该载波建立请求中的第一载波参数为：“带宽＝20M，双工模式＝FDD，制式＝LTE，发送模式＝2T，接收模式＝2R，频段＝2.1GHz”。
应理解，无线设备一般不会直接采用第一载波参数建立第一载波。一般地，无线设备需要先将第一载波参数转换为第一物理资源信息，然后，无线设备再基于第一物理资源信息生成第一载波。具体地，请参阅后文步骤602中的相关介绍。
在另一种可能的实施方式中，该载波建立请求还包括第一物理资源信息。
示例性的，若运营商1通过网管设备在第一无线设备控制器上配置了一个20M带宽的FDD LTE的2T2R载波，使用发送频率2110MHz～2130MHz，接收频率1920MHz～1940MHz。此时，若载波建立请求直接携带第一物理资源信息，该示例中的第一物理资源信息包括：频段资源为“2.1GHz发送频率1950MHz～1970MHz，接收频率2140MHz～2160MHz”，功率资源为“2.1GHz 20W/每通道”，通道资源为“2.1GHz 2T”，上行流数资源为“4流”，下行流数资源为“4流”。
具体地，关于第一载波参数和第一物理资源信息的介绍请参阅前文图2A和图2B中的相关介绍，此处不予赘述。
步骤602，无线设备根据该载波建立请求确定第一物理资源信息。
其中，该第一物理资源信息用于指示建立该第一载波所需要的物理资源。应理解，该第一物理资源信息可以指示一种物理资源，也可以指示多种物理资源。其中，物理资源包括但不限于频段资源、功率资源、通道资源、载波资源以及流数资源。因此，前述第一物理资源信息包括频段资源、功率资源、通道资源、载波资源以及流数资源中的至少一种资源的信息。
此外，关于频段资源、功率资源、通道资源、载波资源以及流数资源的解释请参阅前文图步骤601中的相关介绍，此处不予赘述。
本实施例中，载波建立请求携带的内容不同，无线设备确定第一物理资源信息的方式不同。
在一种可能的实施方式中，该载波建立请求携带的是第一载波参数，该第一载波参数用于指示该第一载波的特征。此时，该无线设备根据该第一载波参数和与该第一无线设备控制器对应的预设规则生成该第一物理资源信息，该至少两个无线设备控制器中不同的无线设备控制器对应的预设规则不同。
其中，预设规则可以理解为无线设备中的业务处理模块(也可以理解为，业务处理软件)的处理逻辑，不同的业务处理模块对应不同的无线设备控制器。若不同的业务处理模块有着不同的业务处理逻辑，则不同的业务处理模块对应不同的预设规则。在本实施例中，可以将预设规则理解为将第一载波参数转换为第一无线资源信息的规则。若将第一载波参数输入至其他的无线设备控制器对应的业务处理模块(例如，第二无线设备控制器对应的第二业务处理模块)，则该第二业务处理模块可能无法识别前述第一载波参数，也可以无法将前述第一载波参数转换为第一物理资源信息。
在另一种可能的实施方式中，该载波建立请求直接携带第一物理资源信息。此时，该无线设备直接从载波建立请求中获取前述第一物理资源信息。
本实施例中，提出了两种载波建立请求的实施方式，也相应地给出了两种确定第一物理资源信息的实施方式。在实际应用中，无线设备可以使用前述任意一种实施方式，具体此处不做限定。
步骤603，无线设备根据第一物理资源信息和第一无线设备控制器对应的物理资源确定是否建立该第一载波。
其中，该至少两个无线设备控制器对应该无线设备中的不同物理资源。也就是说，不同的无线设备控制器能够使用的位于无线设备中的物理资源是不同的，即无线设备中的物理资源被划分给前述至少两个无线设备控制器，并且，前述至少两个无线设备控制器对应该无线设备中的不同物理资源。也就是说，无线设备中的物理资源划分给哪些无线设备控制器，每个无线设备控制器允许使用哪些物理资源等信息是确定的。因此，当该无线设备基于第一物理资源信息获知该第一无线设备控制器在申请建立第一载波时需要使用哪些物理资源时，该无线设备需要确定第一物理资源信息指示的物理资源与该无线设备中该第一无线设备控制器对应的物理资源之间的关系，以确定是否建立该第一载波。
本实施例中，该无线设备存储有第一资源表，该第一资源表包括该至少两个无线设备控制器中每个无线设备控制器对应的物理资源。也就是说，该无线设备通过第一资源表以确定每个无线设备控制器对应的物理资源，即该无线设备将每个无线设备控制器能够使用的物理资源记录在第一资源表中。关于第一资源表可以参阅前文表1-1的相关介绍，此处不予赘述。
示例性的，该第一资源表是用户预选配置的，也可以是无线设备动态生成的。例如，该无线设备接收来自第一无线设备控制器的载波建立请求之前，该无线设备获取资源配置消息，该资源配置消息包括该第一资源表。
由于，该载波建立请求包括该第一无线设备控制器的标识，该第一无线设备控制器的标识用于指示申请该第一无线设备控制器对应的物理资源。因此，该无线设备将先根据该第一无线设备控制器的标识查询该第一资源表中该第一无线设备控制器对应的物理资源。然后， 该无线设备根据第一物理资源信息指示的物理资源的资源量和该第一资源表中该第一无线设备控制器对应的物理资源的资源量确定是否建立该第一载波。
其中，无线设备在确定是否建立第一载波时，可以有如下两种实现方式：
在一种实现中，当该第一物理资源信息指示的物理资源的资源量小于该第一无线设备控制器对应的物理资源的资源量时，该无线设备确定允许建立第一载波，该无线设备将执行步骤604和步骤605。
在另一种实现中，当该第一物理资源信息指示的物理资源的资源量大于该第一无线设备控制器对应的物理资源的资源量时，该无线设备确定该第一无线设备控制器对应的物理资源不足以建立该第一载波，并且，该无线设备将步骤执行步骤604和步骤605，仅执行步骤606。
步骤604，无线设备采用第一物理资源信息指示的物理资源建立该第一载波。
本步骤中，当该第一物理资源信息指示的物理资源的资源量小于该第一无线设备控制器对应的物理资源的资源量时，该无线设备确定允许建立第一载波，并通过该无线设备中的数字处理模块和模拟处理模块建立前述第一载波。其中，数字处理模块包括上变频器、下变频器以及数模转换器等具有数字信号处理功能的电路或器件。模拟处理模块包括中频放大器、滤波器、混频器、功率放大器等具有模拟信号处理功能的电路或器件。
本申请不限定无线设备采用物理资源建立第一载波的实现方式，该无线设备中的数字处理模块和模拟处理模块建立第一载波的方式可以参照传统技术中的方式。
步骤605，无线设备根据第一物理资源信息指示的物理资源的资源量更新第一资源表中第一无线设备控制器对应的物理资源的资源量。
本实施例中，当确定允许基于该第一物理资源信息建立该第一载波之后，该无线设备还将根据该第一物理资源信息指示的物理资源的资源量更新该第一资源表中第一无线设备控制器对应的物理资源的资源量。具体地，该无线设备将第一资源表中第一无线设备控制器对应的物理资源的资源量减去第一物理资源信息指示的物理资源的资源量，得到更新后的第一无线设备控制器对应的物理资源的资源量。
可选的，该无线设备还将存储第一物理资源信息，以记录建立第一载波所使用的物理资源。
步骤606，无线设备向第一无线设备控制器发送载波建立响应。
在一种可能的实现中，若该无线设备在步骤603中确定该第一无线设备控制器对应的物理资源不足以建立第一载波，则该无线设备将向第一无线设备控制器发送的载波建立响应，该载波建立响应携带的内容用于指示第一载波建立失败。本实现中，步骤606与步骤604和步骤605无明确的时间先后顺序的限定，步骤606在步骤603之后执行即可。
在另一种可能的实现中，若该无线设备在步骤603中确定该第一无线设备控制器对应的物理资源足以建立第一载波，并且，该无线设备在步骤604成功建立第一载波，则该无线设备将向第一无线设备控制器发送的载波建立响应，该载波建立响应携带的内容用于指示第一载波建立成功。本实现中，步骤606与步骤605无明确的时间先后顺序的限定，步骤606在步骤604之后执行即可。
本实施例中，由于无线设备能够与多个无线设备控制器连接，并且，该无线设备能够从前述多个无线设备控制器中的某一个无线设备控制器获取载波建立请求，并基于该载波建立 请求确定用于建立载波的物理资源，进而根据前述物理资源和所述无线设备中前述无线设备控制器对应的物理资源确定是否建立载波。因此，能够实现多个无线设备控制器共享一个无线设备，提升了无线设备控制器对应无线设备进行管理的灵活性。
在一种可能的实施方式中，无线设备控制器可以查询该无线设备控制器对应的物理资源的使用情况。具体地，该无线设备接收来自该第一无线设备控制器的资源查询消息，该资源查询消息用于查询该无线设备该第一无线设备对应的物理资源的使用信息，该资源查询消息包括该第一无线设备控制器的标识；该无线设备查询该第一资源表中该第一无线设备控制器对应的物理资源的使用信息；该无线设备向该第一无线设备控制器发送该第一无线设备控制器对应的物理资源的使用信息。
本实施方式中，提出每个业务处理模块可以查询某一个无线设备控制器的物理资源的使用信息，并向该无线设备控制器反馈该无线设备控制器的物理资源的使用信息。有利于避免无线设备将无线设备控制器的物理资源的使用情况误报给该无线设备控制器。
在一种可能的实施方式中，该无线设备还可以以无线设备控制器的粒度上报故障信息。具体地，该无线设备获取故障信息，该故障信息用于指示该无线设备中出现故障的至少一种物理资源；该无线设备从该至少两个无线设备控制器中确定至少一个第二无线设备控制器，该第二无线设备控制器为使用该故障信息指示的物理资源的无线设备控制器；该无线设备向该第二无线设备控制器发送该故障信息。
本实施方式中，提出无线设备能够检测物理资源的故障，并基于物理资源的故障确定故障影响范围，即出现故障的物理资源涉及哪些无线设备控制器(本实施方式称为第二无线设备控制器)。然后，无线设备仅向第二无线设备控制器发送故障信息，而不用向其他无线设备控制器发送故障信息。本实施方式中，有利于无线设备准确地向无线设备控制反馈故障，避免无线设备向与该无线设备连接的全部无线设备控制器反馈故障。
