首先，终端设备接收来自第一网络设备的能力查询消息，该能力查询消息用于指示终端设备向第一网络设备发送能力信息。之后，终端设备响应于第一网络设备的能力查询消息向第一网络设备发送终端设备的能力信息。可以理解，终端设备的能力包括终端设备对应于频段组合的能力，各频段组合包括至少一个频段，各频段组合的频段属于终端设备支持的频段。示例性的，终端设备支持的频段组合包括第一频段组合，该第一频段组合包括第一频段，终端设备发送的能力信息包括第一频段组合的能力信息，且能力信息还可以包括指示终端设备对应于第一频段的能力能够用于终端设备在第二频段对应的小区或载波接收广播服务的第一信息。也即第一网络设备可以根据第一信息确定终端设备的第一能力可以支持终端设备在第二频段对应的小区或载波接收广播服务，其中，第一能力为终端设备对应于第一频段的能力。
在本申请上述实施例方式中，终端设备响应于第一网络设备发送的能力查询消息，向第一网络设备发送能力信息，以使第一网络设备根据能力信息可以获知终端设备基于第一频段组合进行载波聚合通信时，在第二频段的非服务小区上接收广播服务需占用终端设备在第一频段组合的第一频段的服务小区上进行单播和/或组播通信的能力。当终端设备开始在第二频段的非服务小区上接收广播服务，终端设备向第一网络设备上报接收广播服务的频率信息，使得第一网络设备可以根据该频率信息确定与其相关联的用于终端设备进行单播和/或组播通信的频段，停止该频段的单播和/或组播的通信，从而避免终端设备接收广播服务和进行单播/组播通信所占用的硬件能力之和超出终端设备实际支持的总硬件能力，避免发生丢包或误码，保障通信的服务质量。
在第一方面的一种可能的实现方式中，第一信息指示终端设备对应于第一频段组合中的第一频段的能力能够用于支持终端设备在第二频段对应的非服务小区接收广播服务。
在本申请上述实施例方式中，由于终端设备在非服务小区接收广播服务需要占用终端设备部分硬件能力，网络设备根据第一信息可以确定终端设备在第二频段对应的非服务小区接收广播服务需要占用终端设备在第一频段的服务小区进行通信的能力，从而在终端设备在第二频段的非服务小区接收广播服务，且终端设备基于第一频段组合进行载波聚合通信的情况下，可以根据第一信息确定终端设备需要停止第一频段的服务小区的通信，以接收广播服务，避免终端设备接收广播服务和进行单播/组播通信所占用的硬件能力之和超出终端设备实际支持的总硬件能力，以及避免发生丢包或误码，保障通信的服务质量。

在第一方面的一种可能的实现方式中，第一频段组合的频段不包括第二频段，但第二频段为终端设备支持的频段，也即终端设备可以利用第二频段进行通信。示例性的，第二频段与第一频段可以是属于同一运营商的频段，也可以是属于不同运营商的频段。第二频段可以是网络设备查询终端设备的能力信息时，网络设备查询的频段(如：UE-CapabilityRequestFilterNR中指示的频段)；也可以是网络设备没有查询的频段(如：没有在UE-CapabilityRequestFilterNR中指示的频段)。
在本申请上述实施例方式中，第二频段不属于第一频段组合，也即第二频段和第一频段不为一个频段组合下的频段，也即第一信息指示终端设备在第二频段对应的非服务小区接收广播服务和在第一频段组合的服务小区进行单播和/或单播通信时，终端设备接收广播服务和终端设备进行单播和/或组播通信是共享终端设备的硬件资源的，以使网络设备可以根据能力信息进行单播/组播调度，避免终端设备接收广播服务和进行单播/组播通信所占用的硬件能力之和超出终端设备实际支持的总硬件能力，以及发生丢包或误码，从而保障通信的服务质量。
在第一方面的一种可能的实现方式中，在第一频段组合的频段还包括第三频段，且终端设备对应于第一频段组合的第三频段的能力能够用于支持终端设备在第二频段或第四频段对应的小区接收广播服务的情况下，能力信息除了包括第一信息以外，能力信息还可以包括第三信息，第三信息涉及终端设备对应于第三频段的能力，第三信息用于指示终端设备对应于第三频段的能力可以用于支持终端设备在第二频段对应的小区或载波接收广播服务，或者，第三信息用于指示终端设备对应于第三频段的能力可以用于支持终端设备在第四频段对应的小区接收广播服务。其中，第二频段和第四频段为不同的频段。可选的，第四频段不属于第一频段组合。

在第一方面的一种可能的实现方式中，第二信息除了可以指示终端设备接收广播服务的频率之外，还可以指示终端设备接收该广播服务的占用能力，也即第二信息还可以指示终端设备接收广播服务需要占用终端设备对应于整个频段的能力(如：终端设备接收第二频段上非服务小区的广播与第一频段上的单播/组播通信使用相同的射频通道，因此该射频通道要么用于在服务小区上的单播/组播通信，要么用于在非服务小区上的广播接收。当终端设备将该射频通道用于非服务小区上的广播接收时，如果网络设备在该频段上的任意一个载波上调度了单播/组播的数据，则终端设备无法在服务小区上接收到网络设备发送的单播/组播的数据，造成丢包，影响单播/组播的服务质量)，或者指示终端设备接收广播服务需要占用终端设备对应于整个频段的部分载波的能力，且指示占用的载波的数量。
在本申请上述实施例方式中，第二信息除了指示终端设备接收广播服务的频率信息，还指示终端设备接收广播服务需要占用终端设备对应于整个频段的能力还是仅需要占用终端设备对应于整个频段的部分载波的能力，以及占用频段的载波的数量，第二网络设备可以根据第二信息的指示确定需要停止进行单播/组播通信的服务小区的数量，可以避免确定需要停止进行单播/组播通信的服务小区数量过多或过少，影响了终端设备在服务小区与第二网络设备进行通信或接收广播服务的质量。
在第一方面的一种可能的实现方式中，向第二网络设备发送第二信息具体可以为，终端设备判断其接收广播服务是否需要占用目标能力，也即判断接收广播服务是否需要占用终端设备在服务小区与第二网络设备进行通信占用的硬件能力，若是，终端设备才向第二网络设备发送第二信息。

在本申请上述实施例方式中，在非服务小区接收广播服务和进行单播/组播通信未发生冲突的情况下，网络设备可以提前获知终端设备已经开始接收广播服务以及接收广播服务的频率，从而进行合适的单播/组播调度(比如配置能够使得终端设备同时进行单播/组播通信和接收广播服务的频段组合，或者不配置接收广播服务的频率关联的频段上的服务小区，或者不激活相关联的频段上的辅小区)，避免发生冲突以及丢包。
在第一方面的一种可能的实现方式中，终端设备接收第二网络设备根据能力信息以及第二信息确定的第四信息，该第四信息用于指示终端设备停止在第一服务小区进行通信，或者说停止在第一服务小区的数据传输。其中，第一服务小区为第六频段上的至少一个服务小区，第六频段与第五频段关联，该关联指的是，终端设备对应于第六频段的能力能够用于终端设备在第五频段对应的小区接收广播服务。可选的，终端设备对应于第六频段的能力为终端设备在第六频段的服务小区进行通信占用的能力。

在本申请上述实施方式中，由于终端设备不支持同时在第一频段的服务小区进行通信以及在第二频段对应的小区或载波接收广播服务，由此可见，在终端设备需要在第二频段对应的小区或载波接收广播 服务的情况下，需要停止在第一频段的服务小区进行通信。
在第一方面的一种可能的实现方式中，能力信息还可以包括指示信息，该指示信息指示终端设备可以同时在目标频段对应的小区/载波接收广播服务以及在第一频段组合上的服务小区进行通信。其中，目标频段可以包括一个或多个频段。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请提供的技术方案可以应用于各种通信***，请参考图1，其示出了本申请的实施例应用的通信***1000的架构示意图。如图1所示，该通信***包括无线接入网100和核心网200，可选的，通信***1000还可以包括互联网300。其中，无线接入网100可以包括至少一个网络设备(如图1中的110a和110b)，还可以包括至少一个终端设备(如图1中的120a-120j)。终端设备通过无线的方式与网络设备相连，网络设备通过无线或有线方式与核心网连接。核心网设备与网络设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与网络设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的网络设备的功能。终端设备和终端设备之间以及网络设 备和网络设备之间可以通过有线或无线的方式相互连接。图1只是示意图，该通信***中还可以包括其它设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。
网络设备是终端设备通过无线方式接入到通信***中的接入设备。网络设备可以是基站(base station)、接入点、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信***中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信***中的下一代基站、未来移动通信***中的基站或WiFi***中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。这里的CU完成基站的无线资源控制协议和分组数据汇聚层协议(packet data convergence protocol，PDCP)的功能，还可以完成业务数据适配协议(service data adaptation protocol，SDAP)的功能；DU完成基站的无线链路控制层和介质访问控制(medium access control，MAC)层的功能，还可以完成部分物理层或全部物理层的功能，有关上述各个协议层的具体描述，可以参考第三代合作伙伴计划(3rd generation partnership project，3GPP)的相关技术规范。网络设备可以是宏基站(如图1中的110a)，也可以是微基站或室内站(如图1中的110b)，还可以是中继节点或施主节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为了便于描述，下文以基站作为网络设备的例子进行描述。
终端设备是具有无线收发功能的设备，可以向基站发送信号，或接收来自基站的信号。终端设备也可以称为终端、用户设备(user equipment，UE)、移动台、移动终端等。终端设备可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。基站和终端设备可以是固定位置的，也可以是可移动的。基站和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在飞机、气球和人造卫星上。本申请的实施例对基站和终端设备的应用场景不做限定。终端设备可以支持多种不同的通信制式，例如，LTE和NR等。
基站和终端设备的角色可以是相对的，例如，图1中的直升机或无人机120i可以被配置成移动基站，对于那些通过120i接入到无线接入网100的终端设备120j来说，终端设备120i是基站；但对于基站110a来说，120i是终端设备，即110a与120i之间是通过无线空口协议进行通信的。当然，110a与120i之间也可以是通过基站与基站之间的接口协议进行通信的，此时，相对于110a来说，120i也是基站。因此，基站和终端设备都可以统一称为通信装置，图1中的110a和110b可以称为具有基站功能的通信装置，图1中的120a-120j可以称为具有终端设备功能的通信装置。
基站和终端设备之间、基站和基站之间、终端设备和终端设备之间可以通过授权频谱进行通信，也可以通过免授权频谱进行通信，也可以同时通过授权频谱和免授权频谱进行通信；可以通过6千兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请的实施例对无线通信所使用的频谱资源不做限定。
在本申请的实施例中，基站的功能也可以由基站中的模块(如芯片)来执行，也可以由包含有基站功能的控制子***来执行。这里的包含有基站功能的控制子***可以是智能电网、工业控制、智能交通、智慧城市等上述应用场景中的控制中心。终端设备的功能也可以由终端设备中的模块(如芯片或调制解调器)来执行，也可以由包含有终端设备功能的装置来执行。
在本申请中，基站向终端设备发送下行信号或下行信息，下行信息承载在下行信道上；终端向基站发送上行信号或上行信息，上行信息承载在上行信道上。终端设备为了与基站进行通信，需要与基站控制的小区建立无线连接。与终端设备建立了无线连接的小区称为该终端设备的服务小区。当终端设备与该服务小区进行通信的时候，还会受到来自邻区的信号的干扰。
载波聚合(carrier aggregation，CA)是一种常用的增加通讯带宽的手段，载波聚合技术是通过 多个分量载波(Component Carrier，CC)(下文简称为载波)同时为终端设备提供服务。现有的载波聚合技术中，通常有一个载波对应的小区为主小区，其他载波对应的小区为辅小区。辅小区使用过程可以进行激活或去激活，如果一段时间没有数据传输，网络可能会去激活辅小区，后续再有数据发送时再确定是否激活辅小区。载波聚合包括单个频段的多个载波之间的聚合，也包括多个频段的多个载波之间的聚合。
不同终端设备由于硬件或软件版本的不同，不同的终端设备能力并不相同，网络设备需要知道终端设备的能力，才能为终端设备配置合适的工作模式。NR的UE能力中，根据UE能力的层次可以划分为UE级的能力，频段级的能力以及频段组合(band combination，BC)级的能力。其中，UE级的能力包括：UE支持的协议版本、射频参数(RF-parameters)、分组数据汇聚协议参数(PDCP-parameters)、媒体接入控制参数(MAC-parameters)以及无线链路控制参数(RLC-parameters)等。频段级的能力为与具体频段相关的能力。BC级的能力为和BC相关的能力，主要用于表明终端设备的CA能力。示例性的，如图2所示，终端会上报其支持的BC列表，并指示每个BC包含哪些频段，其中，对于只支持一个频段的情况，也是通过该结构进行上报的。
NR多播广播服务(multicast/broadcast service，MBS)是指网络设备同时向某个地理区域中的所有终端设备提供相同的特定内容数据的通信服务模式。支持NR MBS广播的终端设备可以在无线能力控制(Radio Resource Control，RRC)连接态、RRC空闲态、和RRC非激活态下获取广播服务，在RRC连接态，R17标准支持终端设备通过服务小区接收广播服务。
R18标准中引入了终端设备可以在非服务小区上接收广播，所述非服务小区可以属于与服务小区的单播/组播通信属于同一运营商，也可以属于不同运营商。终端设备在非服务小区上接收广播服务和在服务小区上接收单播服务共享终端设备的硬件能力(或者说硬件资源)。目前，UE能力中上报的BC级的能力是根据终端设备的硬件能力所能够支持的载波聚合的能力进行上报的。然而，由于终端设备在非服务小区接收广播服务占用了部分终端设备的硬件能力，在终端设备在非服务小区上接收广播服务的情况下，若提供单播服务的基站无法获知终端设备实际可用于接收单播服务的硬件能力，可能会导致终端设备进行单播通信和在非服务小区接收广播服务占用的硬件能力发生冲突，或者说进行单播通信和在非服务小区接收广播服务占用的硬件能力之和超出终端实际支持的硬件能力。在发生硬件能力冲突的情况下，无论终端设备选择停止进行单播通信或者停止接收广播服务，都会影响业务的服务质量，影响用户体验。
有鉴于此，本申请实施例提供了一种通信方法，在该方法中，终端设备的能力信息可指示终端设备对应于第一频段组合的第一频段的能力用于终端设备在第二频段对应的小区或载波接收广播服务，或者终端设备的能力信息指示终端设备对应于第一频段组合的第一频段的第一载波的能力用于终端设备在第二频段对应的小区或载波接收广播服务。与终端设备的服务小区对应的网络设备在获知终端设备的能力信息以及终端设备接收广播服务的频率的情况下，可以根据能力信息指示终端设备停止在对应的服务小区进行通信，以使终端设备接收广播服务以及在服务小区与该网络设备进行通信所占用的能力不同，避免终端设备接收广播服务和在服务小区与网络设备进行通信占用的硬件能力冲突。
请参考图3，其示出了本申请第一实施例提供的通信方法，可以应用于如图1所示的通信***，如图3所示，该通信方法可以包括步骤301至步骤302。
步骤301，第一网络设备向终端设备发送能力查询消息。
其中，第一网络设备为向终端设备查询能力信息的网络设备，如：第一网络设备为终端设备入网时对应的网络设备，或者为终端设备的能力信息发生变化时，与终端设备进行通信的网络设备，本申请不对第一网络设备做限定，只要该网络设备需要终端设备上报能力，并且能够获取终端设备的能力信息即可为本实施例所述的第一网络设备。可选的，能力信息可以指终端设备的无线接入能力(radio access capability)信息。本申请实施例所述的终端设备为支持进行单播通信和支持接收广播服务的终端设备。所述广播服务可以为MBS广播服务。本步骤中的能力查询消息可以是UE capability enquiry消息，用于请求终端设备的无线接入能力。
步骤302，终端设备向第一网络设备发送能力信息，能力信息包括第一频段组合的能力信息，第一频段组合中的频段包括第一频段，能力信息还包括第一信息，第一信息指示终端设备对应于第一频段的 能力用于终端设备在第二频段对应的小区上接收广播服务。
其中，第一频段组合的频段属于终端设备支持的频段，可以理解的，第一频段为终端设备支持的频段，终端设备可以在第一频段的服务小区进行通信。终端设备通过能力信息上报第一频段组合的能力，包括第一频段组合的BC级能力(比如CA能力参数、MRDC能力参数、NRDC能力参数等)、第一频段组合包括的频段的能力(比如第一频段组合包括的频段标识、CA带宽等级等)、第一频段组合关联的特性集组合FeatureSetCombination、第一频段组合包括的各个频段关联的特性集FeatureSetPerBand、第一频段组合中的频段中的载波关联的特性集FeatureSetPerCC等。终端设备在接收到第一网络设备的能力查询消息的情况下，会根据能力查询消息向第一网络设备发送能力信息。
可以理解的，终端设备支持一个或多个频段组合进行载波聚合，各频段组合中包括一个或多个频段。可选的，能力信息可以包括至少一个频段组合的能力信息。可选的，第一频段组合为终端设备支持进行载波聚合的频段组合中的一个。
可选的，终端设备对应于第一频段的能力为终端设备在第一频段组合下，在第一频段的服务小区进行通信的能力，比如第一频段关联的特性集FeatureSetDownlink和FeatureSetUplink。终端设备对应于第一频段的能力为终端设备在第一频段的服务小区进行通信的能力，终端设备在第一频段的服务小区进行通信的能力可以理解为终端设备在第一频段的服务小区进行数据传输的能力。终端设备在第一频段的服务小区进行的通信可以包括单播通信和/或组播通信。终端设备在第一频段的服务小区进行通信的能力包括终端设备在第一频段的服务小区进行通信占用的硬件能力，硬件能力可以包括但不限于为基带能力或射频能力(如：射频集成电路(RFIC)上的射频通道以及射频前端模块)。由于第一信息可以指示终端设备在第一频段的服务小区进行通信占用的基带能力和射频能力用于终端设备在第二频段对应的小区/载波接收广播服务，因此，网络设备基于本实施例的能力信息进行调度，可以避免终端设备接收广播服务和进行单播和/或组播通信超过终端设备实际支持的基带能力和射频能力。
其中，频段组合中的频段可以对应一个或多个载波或小区，终端设备在频段对应的载波或小区接收广播服务可以为终端设备在该频段对应的任一载波或小区接收广播服务。可选的，第二频段对应的小区为第二频段对应的任一小区。接收广播服务可以理解为接收广播业务数据。可选的，第二频段对应的小区可以为终端设备的非服务小区，也即第一信息指示终端设备对应于第一频段的能力用于终端设备在第二频段对应的非服务小区上接收广播服务。可选的，第二频段为终端设备支持的频段，且第二频段不属于第一频段组合。
应说明的是，第一信息指示的是第一能力的作用，第一能力为终端设备对应于第一频段的能力，也即第一信息指示的是第一能力能够用于终端设备在第二频段对应的小区或载波接收广播服务，不是第一能力必须用于终端设备在第二频段对应的小区或载波接收广播服务，或者第一能力只能用于终端设备在第二频段对应的小区或载波接收广播服务，如下文指出，第一能力也可以用于终端设备在其他频段对应的小区或载波接收广播服务。应说明的是，第一信息指示终端设备基于第一频段组合进行载波聚合通信的情况下，终端设备在第二频段接收广播服务占用终端设备对应于第一频段的能力。在一种情况中，当终端设备基于另一频段组合(该频段组合包括第一频段)进行载波聚合通信的情况下，终端设备在第二频段接收广播服务并不占用终端设备对应于第一频段的能力。
可选的，终端设备对应于第一频段的能力用于终端设备在第二频段对应的小区或载波接收广播服务时，终端设备对应于第一频段的能力不支持终端设备在第一频段的服务小区进行通信。可选的，第一硬件资源用于终端设备在第二频段对应的小区或载波接收广播服务时，第一硬件能力无法用于终端设备在第一频段的服务小区进行通信，其中，第一硬件能力为终端设备在第一频段的服务小区进行通信占用的硬件能力。可选的，终端设备对应于第一频段的能力用于终端设备在第二频段对应的小区或载波接收广播服务时，终端设备不支持在第一频段的服务小区进行通信。由于终端设备无法同时在第二频段对应的小区或载波接收广播服务以及在第一频段的服务小区上进行通信，因此在终端设备需要在第二频段对应的小区或载波接收广播服务的情况下，终端设备需要停止在第一频段的至少一个服务小区上进行通信，以避免终端设备接收广播服务和在服务小区进行通信占用的硬件能力之和超出终端设备实际支持的总硬件能力。
如上文所述，终端设备对应于第一频段的能力用于终端设备在第二频段对应的小区或载波接收广播服务，在一种情况下，终端设备对应于第一频段的能力还用于终端设备在另外的一个或多个频段(与第二频段不同的频段)对应的小区接收广播服务，在该情况下，终端设备向第一网络设备发送的能力信息，还可以包括指示终端设备对应于第一频段的能力用于终端设备在另外的一个或多个频段对应的小区接收广播服务的信息。可以理解为，第一信息指示对应于第一频段的能力关联于一个频段列表，该频段列表包括终端设备用于接收广播服务的频段，所述广播服务为终端设备在非服务小区上接收的广播服务。
当第一频段组合包括多个频段时，在一种情况下，终端设备对应于第一频段组合中另外的一个或多个频段用于终端设备在第二频段和/或另外的至少一个频段对应的小区接收广播服务，也即第二能力用于终端设备在第二频段对应的小区或载波接收广播服务，和/或第二能力用于终端设备在另外的至少一个频段对应的小区接收广播服务，其中，第二能力为终端设备对应于频段集合中的频段的能力，频段集合中的频段为第一频段组合中除第一频段之外的频段。在该情况下，终端设备向第一网络设备发送的能力信息，还可以包括指示终端设备对应于第一频段组合中另外的一个或多个频段用于终端设备在第二频段和/或另外的至少一个频段对应的小区接收广播服务的信息。
示例性的，第一频段组合还可以包括第三频段，能力信息还可以包括第三信息，第三信息指示终端设备对应于第三频段的能力用于终端设备在第二频段和/或第四频段对应的小区上接收广播服务。其中，第一频段、第二频段、第三频段以及第四频段为不同的频段。应说明的是，终端设备对应于第三频段的能力为终端设备在第三频段的服务小区进行通信的能力。在第一种情况中，第三信息指示终端设备对应于第三频段的能力用于终端设备在第二频段对应的小区或载波接收广播服务。在第二种情况中，第三信息指示终端设备对应于第三频段的能力用于终端设备在第四频段对应的小区接收广播服务。在第三种情况中，第三信息指示终端设备对应于第三频段的能力用于终端设备在第二频段和第四频段对应的小区接收广播服务。
上述实施例展示出频段组合中的频段与接收广播服务对应的频段的部分情况，下面将通过一个例子进行补充说明，第一频段组合包括bandA、bandB和bandC，终端设备支持在bnadQ、bnadP、bandE、bandM和bandN接收广播服务。
在第一种情况中，第一信息指示终端设备对应于bandA的能力用于终端设备在bandQ对应的小区接收广播服务，第三信息指示终端设备对应于bandB的能力用于终端设备在bandQ对应的小区接收广播服务。
在第二种情况中，第一信息指示终端设备对应于bandA的能力用于终端设备在bandQ对应的小区接收广播服务，第三信息指示终端设备对应于bandB的能力用于终端设备在bandP对应的小区接收广播服务。
在第三种情况中，第一信息指示终端设备对应于bandA的能力用于终端设备在bandQ对应的小区接收广播服务，第三信息指示终端设备对应于bandB的能力用于终端设备在bandQ和bandP对应的小区接收广播服务。应说明的，终端设备对应于bandB的能力用于终端设备在bandQ和bandP对应的小区接收广播服务，一种情况为，终端设备对应于bandB的能力用于终端设备同时在bandQ和bandP对应的小区接收广播服务。另一种情况为，终端设备对应于bandB的能力用于终端设备在bandQ对应的小区接收服务，或者，终端设备对应于bandB的能力用于终端设备在bandP对应的小区接收广播服务。
第四种情况中，第一信息指示终端设备对应于bandA的能力用于终端设备在bandP和bandQ对应的小区接收广播服务，第三信息指示终端设备对应于bandB的能力用于终端设备在bandP、bandE和bandM对应的小区接收广播服务。
应说明的是，上述例子仅仅是通过举例对频段组合中的频段与接收广播服务对应的频段之间的关系进行说明，并不应理解为对本方案的具体限定，频段组合中的频段与接收广播服务对应的频段之间的关系由终端设备的实际能力决定，终端设备向第一网络设备发送的能力信息可以指示如上述实施例所示的频段组合中的频段与接收广播服务对应的频段之间的关系。
应说明的，如上述实施例，终端设备对应于第一频段组合中各频段的能力可能均无法用于终端设备在某一频段(如上述实施例的bandN)对应的小区接收广播服务，但是终端设备对应于其他的频段组合 中的频段的能力可能可以用于终端设备在该某一频段对应的小区接收广播服务。可选的，终端设备上报的能力信息除了包括第一频段组合的能力信息，还可以包括其他频段组合的能力信息。示例性的，能力信息还包括第三频段组合的能力信息，第三频段组合的频段属于终端设备支持的频段，第三频段组合的频段包括第七频段，能力信息还包括第六信息，第六信息指示终端设备对应于第七频段的能力用于终端设备在第八频段对应的小区接收广播服务。其中，第八频段可以是与第二频段相同的频段，也可以是与第二频段不同的频段。
如上述实施例所述，当终端设备在第一频段组合中进行单播/组播的通信的情况下，终端设备可以同时在bandN对应的小区/载波接收广播服务。也即终端设备在第一频段组合上的单播/组播通信只占用了部分的终端设备的能力，终端设备剩余的能力能够支持终端设备在bandN对应的小区/载波接收广播服务。
示例性的，能力信息还包括指示信息，该指示信息用于指示终端设备在第一频段组合上的服务小区进行通信时，终端设备可以同时支持在目标频段上接收广播服务，其中目标频段可以包括一个或多个频段。示例性的，指示信息可以为第一频段组合关联的特性集包括目标频段标识，也即第一频段组合关联的特性集包括目标频段标识，则表示终端设备在第一频段组合上的服务小区进行通信时，终端设备可以同时支持在目标频段上接收广播服务。其中，目标频段标识用于指示目标频段。
网络设备在确定接收广播服务的频率，可以根据该频率以及指示信息，重配置对应于终端设备的频段组合，以使终端设备可以同时接收广播服务和进行单播/组播通信。可选的，网络设备可以通过RRC重配置消息将该重配置的频段组合发送至终端设备。
在终端设备同时接收广播服务和在服务小区进行通信所占用的硬件能力之和超出终端设备实际支持的硬件能力的情况下，终端设备的服务小区对应的网络设备确定终端设备正在接收或者感兴趣接收广播服务的第五频段，然后根据第一信息确定与第五频段具有关联的第六频段(关联指的是终端设备对应于第六频段的能力用于终端设备在第五频段对应的小区接收广播服务)，指示终端设备停止在第六频段的至少一个服务小区的数据传输，则终端设备可以利用终端设备对应于该服务小区的能力接收广播服务，并利用剩余的服务小区进行通信，此时终端设备在服务小区进行通信和接收广播服务占用终端设备不同的硬件能力，可以避免终端设备在服务小区进行通信和接收广播服务占用的硬件能力之和超过终端实际支持的硬件能力。
应说明的，在终端设备在某一频段的服务小区进行通信的情况下，停止某一频段的服务小区通信，指的是停止在该某一频段的服务小区继续进行通信，包括停止在该某一频段的服务小区下行和上行的资源调度，停止发送数据和信令。在某一频段内的载波没有配置为服务小区，或者配置为了服务小区但该服务小区是去激活状态的辅小区的情况下，停止在某一频段的服务小区进行通信指的是，网络设备可以不将该某一频段的载波配置为服务小区，或不激活该某一频段上的辅小区。
在一个实施例中，第一信息包括第一频段与第二频段的第一关联信息，该第一关联信息指示终端设备对应于第一频段的能力能够用于支持终端设备在第二频段对应的小区或载波接收广播服务。
请继续参考图2，在一个实施例中，第一信息为第一频段组合的第一频段关联的特性集包括第二频段标识，第二频段标识指示第二频段，第一频段组合的第一频段关联的特性集包括第二频段标识则表示终端设备对应于第一频段的能力用于终端设备在第二频段对应的小区或载波接收广播服务。第二频段标识可以是第二频段对应的频率范围，或者是第二频段的频率范围的中心频率，也可以是与第二频段对应的编号，其中，不同的编号对应的频段不同。本实施例不对第二频段标识的形式作限定，只要根据第二频段标识能唯一确定第二频段即可。
本实施例在终端设备对应于第一频段的能力能够用于终端设备在第二频段对应的小区或载波接收广播服务的情况下，通过在与第一频段关联的特性集中增加第二频段标识，并将该与第一频段关联的特性集发送至第一网络设备，使得第一网络设备可以根据终端设备发送的能力信息确定第一频段组合中的第一频段和第二频段的第一关联关系，从而在终端设备在第一频段组合进行载波聚合通信，且在第二频段对应的小区或载波接收广播服务时，与终端设备的服务小区对应的网络设备可以确定需要停止在第一频段的至少一个服务小区进行通信，以避免终端设备同时接收广播服务和在服务小区进行通信所占用的 硬件能力之和超出终端设备实际支持的硬件能力。
同时，本申请实施例向网络设备发送的特性集组合对应的频段组合的频段并不包括接收广播服务对应的频段，仅是将与接收广播服务对应的频段的标识增加到对应的频段组合级的特性集组合中，相对于终端设备向网络设备发送第四频段组合(终端设备在服务小区进行通信的频段和接收广播服务的频段的频段组合)，并将第四频段组合的特性集组合发送给网络设备而言，本实施例没有增加新的频段组合(第四频段组合)的能力信息，信令开销较小。而且由于接收广播服务的频段可能为网络设备不支持的频段，若此时发送给终端设备的能力查询消息携带有过滤信息，网络设备将无法获得第四频段组合，也即无法避免终端设备同时接收广播服务和在服务小区进行通信占用的硬件能力之和不超过终端设备实际支持的硬件能力的情况，但是本实施例无需产生新的频段组合(第四频段组合)，因此即使能力查询消息携带有过滤信息，终端设备还是可以根据能力信息确定需要停止进行通信的服务小区，以避免终端设备同时接收广播服务和在服务小区进行通信占用的硬件能力之和超过终端设备实际支持的硬件能力。
请继续参考图3，在上述实施例的基础上，该通信方法还可以包括步骤303和步骤304，相对于上述实施例，终端设备除了向第一网络设备发送能力信息之外，终端设备在获知接收广播服务的频率信息的情况下，向第二网络设备发送第二信息，以使第二网络设备获知终端设备接收广播服务的频率，从而为第二网络设备可以根据能力信息确定终端设备需要停止的服务小区提供了条件。
步骤303，终端设备向第二网络设备发送第二信息。
应说明的，第二网络设备为终端设备的服务小区对应的网络设备。本实施例所述的第二信息包括终端设备接收广播服务相关的信息。本申请实施例所说的终端设备接收广播服务包括但不限于终端设备即将要接收广播服务以及终端设备正在接收广播服务。其中，终端设备即将要接收广播服务可以理解为终端设备已经确定需要接收广播服务，但是终端设备还处于为接收该广播服务的准备阶段。可选的，终端设备接收广播服务为终端设备在非服务小区接收广播服务。可选的，接收的广播服务为MBS广播服务。可选的，终端设备接收广播服务的频率不属于第二网络设备的频率范围，或者说终端设备接收广播服务的频点不为目标运营商的频点，目标运营商为第二网络设备所属的运营商。可选的，第二信息可以为MBS兴趣指示信息(MBS Interest Indication，MII)，或者为UE辅助信息(UE assistance information，UAI)。
在终端设备即将接收广播服务或者已经开始接收广播的情况下，终端设备向第二网络设备发送第二信息，以使第二网络设备获知终端设备接收广播服务的相关信息。在一个实施例中，终端设备向第二网络设备发送第二信息的步骤之前，通信方法还可以包括，第二网络设备指示允许终端设备在第一小区上上报第二信息，可选的，第二网络设备指示允许终端设备在第一小区上满足触发条件的情况下上报第二信息，其中，触发条件为终端设备即将开始接收或者已经开始接收广播服务。可选的，所述指示通过***消息发送给第一小区上的终端设备。其中，第一小区为终端设备可以进行通信的小区。其中，第一小区可以为终端设备接入的主小区。
在一个实施例中，向第二网络设备发送第二信息的步骤，包括：在确定终端设备接收广播服务占用目标能力的情况下，向第二网络设备发送第二信息。其中，目标能力包括终端设备在服务小区上与第二网络设备进行通信占用的硬件能力。应说明的，对于终端设备在多个服务小区与第二网络设备进行通信的情况，目标能力包括终端设备在各服务小区上与第二网络设备进行通信占用的硬件能力之和。终端设备可以判断接收广播服务是否会占用目标能力，或者说终端设备可以判断接收广播服务和与第二网络设备进行通信占用的硬件能力之和是否超过终端设备实际支持的总硬件能力。本实施例中，通过终端设备判断终端设备接收广播服务是否需要占用目标能力，并且在确定终端设备接收广播服务需占用目标能力的情况下，才向第二网络设备发送第二信息，无需第二网络设备进行判断。
在一个实施例中，向第二网络设备发送第二信息的步骤，包括：在终端设备开始在非服务小区接收广播服务的情况下，向第二网络设备发送第二信息。在该实施例中，包括终端设备在非服务小区接收广播服务和进行单播/组播通信未发生冲突的情况，在该情况下，网络设备提前获知终端设备已经开始接收广播服务以及接收广播服务的频率，从而进行合适的单播/组播调度，如：配置能够使得终端设备同时进行单播/组播通信和接收广播服务的频段组合，或者不配置接收广播服务的频率关联的频段上的服 务小区，或者不激活相关联的频段上的辅小区，避免发生终端设备进行单播/组播通信和接收广播服务冲突以及丢包。
在一个实施例中，第二信息可以指示终端设备接收广播服务的频率信息，使得第二网络设备在终端设备接收广播服务占用目标能力的情况下，可以根据广播服务的频率信息确定接收广播服务的频率，并根据接收广播服务的频率以及能力信息确定终端设备需要停止通信的服务小区。可选的，频率信息可以为频点(absolute radio frequency channel number，ARFCN)也即第二信息包括终端设备接收广播服务的频点。第二网络设备根据终端设备接收的广播服务的频率，可以确定该频率所属的第五频段，从而根据能力信息确定与第五频段关联的第六频段，从而确定需要停止通信的服务小区，第六频段与第五频段关联指的是终端设备对应于第六频段的能力用于终端设备在第五频段对应的小区接收广播服务。
第二信息还可以指示终端设备接收广播服务占用频段关联的能力或指示终端设备接收广播服务占用频段的载波关联的能力，其中，占用频段的载波关联的能力包括占用频段的载波的数量。应说明的，第二信息指示终端设备接收广播服务占用频段关联的能力可以理解为，第二信息指示终端设备接收广播服务需要占用终端设备对应于整个频段的能力，也即需要占用终端设备对应于频段下的所有载波的能力，如：终端设备接收第二频段上非服务小区的广播与第一频段上的单播/组播通信使用相同的射频通道，因此该射频通道要么用于在服务小区上的单播/组播通信，要么用于在非服务小区上的广播接收。当终端设备将该射频通道用于非服务小区上的广播接收时，如果网络设备在该频段上的任意一个载波上调度了单播/组播的数据，则终端设备无法在服务小区上接收到网络设备发送的单播/组播的数据，造成丢包，影响单播/组播的服务质量，在该情况下第二信息指示终端设备接收广播服务占用频段关联的能力。第二信息指示终端设备接收广播服务占用频段的载波关联的能力可以理解为，第二信息指示终端设备接收广播服务需要占用终端设备对应于整个频段下的第三载波集合中的所有载波的能力，且指示第三载波集合中载波的数量。可以理解的，第一载波集合中载波的数量少于该频段包含的载波的数量。
在一个实施例中，第二信息还可以指示服务优先级。应说明的是，服务优先级指的是终端设备接收广播服务和在服务小区与第二网络设备进行通信的优先级。示例性的，第二信息指示终端设备接收广播服务的优先级高于在服务小区与第二网络设备进行通信的优先级，第二网络设备可以停止在一个或多个服务小区与第二网络设备进行通信，以将终端设备对应于该一个或多个服务小区的能力用于接收广播服务。示例性的，第二信息指示终端设备接收广播服务的优先级低于在服务小区与第二网络设备进行通信的优先级，第二网络设备可以继续沿用当前的服务小区与第二网络设备进行通信。在一个实施例中，第二信息包括广播会话标识(temporary mobile group identity，TMGI)。
步骤304，第二网络设备接收第二信息。
第二网络设备根据第二信息可以获知终端设备接收广播服务的频率，并使得第二网络设备可以根据该频率确定与其相关联的用于单播和/或组播的频段，停止该频段的单播和/或组播的通信，从而避免终端设备接收广播服务和进行单播/组播通信所占用的硬件能力之和超出终端设备实际支持的总硬件能力，避免发生丢包或误码，保障通信的服务质量。
请继续参考图3，在上述实施例的基础上，该通信方法还可以包括步骤305，相对于上述实施例，步骤305具体阐述了第二网络设备如何根据能力信息以及第二信息确定终端设备需要停止进行通信的服务小区。
步骤305，第二网络设备根据能力信息以及第二信息确定第四信息。
如上述步骤所说，终端设备接收广播服务和进行单播和/或组播可能发生冲突或未发生冲突，针对于该两种情况，分别对本步骤进行说明。
针对第一种情况(终端设备接收广播服务和进行单播和/或组播发生冲突)，第四信息指示终端设备停止在第一服务小区的数据传输，第一服务小区为终端设备接收广播服务的第五频段关联的第六频段上的至少一个服务小区。应说明的是，第六频段为终端设备与第二网络设备进行通信的频段，且终端设备对应于第六频段的能力用于终端设备在第五频段对应的小区接收广播服务。第二网络设备可以根据第二信息确定终端设备接收广播服务对应的频段(第五频段)，根据能力信息确定与第五频段关联的频段(第六频段)，并指示终端设备停止在第六频段的至少一个服务小区进行单播通信。应说明的，根据能力信 息和第二信息可能可以确定出一个或i个第六频段，i为大于等于2的整数。在确定出i个第六频段的情况下，第二网络设备可以按照预设规则选中i个第六频段中的一个。可选的，第二网络设备选中的第六频段为i个第六频段中信道质量最差的频段，指示终端设备停止在该选中的第六频段的至少一个服务小区的通信。可选的，第二网络设备选中i个第六频段中重要程度最低的第六频段，指示终端设备停止在重要程度最低的第六频段的至少一个服务小区进行通信。其中，频段的重要程度可以根据频段传输的数据的重要程度衡量。根据上述实施例描述可知，第二信息还指示终端设备接收广播服务占用频段关联的能力或指示终端设备接收广播服务占用频段的载波关联能力。在第二信息指示终端设备接收广播服务占用频段关联的能力的情况下，第二网络设备可以确定第一服务小区为第六频段上所有的载波/载波关联的服务小区，也即第一服务小区为第六频段对应的所有服务小区。在第二信息指示终端设备接收广播服务占用频段的载波的能力，且占用频段的载波的数量为N(N为大于等于1的整数)的情况下，第二网络设备可以确定第一服务小区为第六频段上的N个载波/载波关联的服务小区。在一个实施例，在第六频段具有i个的情况下，第二网络设备可以在i个第六频段对应的所有服务小区中选中N个服务小区，该N个服务小区即为第一服务小区，本实施例不限定N个服务小区一定要是同一个第六频段下的服务小区，也即第一服务小区的服务小区数量与占用频段的载波关联的能力指示的占用频段的载波的数量一致即可。
请继续参考图3，在第一种情况，该通信方法还可以包括步骤306，相对于上述实施例，第二网络设备在确定第四信息后向终端设备发送第四信息，以指示终端设备停止在第一服务小区进行通信。
步骤306，第二网络设备向终端设备发送第四信息。
第二网络设备向终端设备发送第四信息以指示终端设备停止在第一服务小区的数据传输，从而使得终端设备在第一服务小区进行数据传输占用的终端设备的能力被释放，终端设备通过释放的能力在第五频段对应的小区接收广播服务，通过其他的服务小区(未停止的服务小区)与第二网络设备进行通信，使得终端设备通过不同的能力接收广播服务和在服务小区与第二网络设备进行通信，避免终端设备同时接收广播服务和在服务小区与第二网络设备进行通信占用的硬件能力之和超过终端设备实际支持的硬件能力。
针对第二种情况(终端设备接收广播服务和进行单播和/或组播未发生冲突)，第四信息指示网络设备不将第二小区配置为服务小区或激活，应说明的，在第二小区为非激活状态的辅小区的情况下，第四信息指示网络设备不激活该第二小区。应说明的，第二小区可以为一个或多个小区。第二小区所属的频段为终端设备接收广播服务的频率对应的频段的关联频段，也即第一终端设备对应于第二小区所属的频段的能力用于终端设备接收该频率的广播服务。
应说明的，图3对应的实施例中，第一网络设备和第二网络设备为不同的网络设备。终端设备在满足切换条件或小区重选条件的情况下，会更换驻留的服务小区，与不同的网络设备建立连接，因此在终端发送第二信息时驻留的小区所关联的第二网络设备可能是与第一网络设备相同的网络设备，也可能是与第一网络设备不相同的网络设备。可选的，在第二网络设备与第一网络设备不同的情况下，也即终端设备从与第一网络设备切换为与第二网络设备连接的情况下，第一网络设备将终端设备的能力信息发送给第二网络设备，以使第二网络设备获得终端设备的能力信息。
请参考图4，图4所示的通信方法与图3所示的通信方法的区别在于图4的第一网络设备和第二网络设备为同一网络设备，步骤401至步骤406的描述与图3步骤301至步骤306的描述类似，在此不再赘述。
请参考图5，其示出了本申请另一实施例提供的通信方法，可以应用于如图1所示的通信***，本实施例提供的通信方法与图3对应的通信方法的区别在于两个实施例中终端设备发送的能力信息。如图5所示，该通信方法可以包括步骤501至步骤502。
步骤501，第一网络设备向终端设备发送能力查询消息。
其中，步骤501与图3对应的实施例中的步骤301类似，在此不再赘述。
步骤502，向第一网络设备发送能力信息，能力信息包括第一频段组合的能力信息，第一频段组合的频段包括第一频段，第一频段包括第一载波，能力信息还包括第五信息，第五信息指示终端设备对应 于第一载波的能力用于终端设备在第二频段对应的小区接收广播服务。
其中，第一频段组合、第一频段组合的能力以及“终端设备在第二频段对应的小区接收广播服务”的描述与图3对应的实施例中的第一频段组合、第一频段组合的能力以及“终端设备在第二频段对应的小区接收广播服务”的描述类似，在此不再赘述。终端设备支持的各频段组合包括一个或多个频段，各频段可以包括一个或多个载波，其中，第一频段组合的频段包括第一频段，第一频段包括第一载波，第一频段组合的频段属于终端设备支持的频段，第一频段组合中的第一频段的载波为终端设备支持的载波，也即终端设备支持在第一载波的服务小区进行通信。可以理解的，不同频段组合下的同一频段对应的载波可以相同也可以不同。
可选的，终端设备对应于第一载波的能力为终端设备在第一频段组合下，在第一载波的服务小区进行通信的能力，终端设备对应于第一载波的能力为终端设备在第一载波的服务小区进行通信的能力，终端设备在第一载波的服务小区进行通信的能力可以理解为终端设备在第一载波的服务小区进行数据传输的能力。终端设备在第一载波的服务小区进行的通信可以包括单播通信和/或组播通信。终端设备在第一载波的服务小区进行通信的能力包括终端设备在第一载波的服务小区进行通信占用的硬件能力，硬件能力可以包括但不限于为基带能力或射频能力(如：射频集成电路(RFIC)上的射频通道以及射频前端模块)。由于第五信息可以指示终端设备在第一载波的服务小区进行通信占用的基带能力和射频能力用于终端设备在第二频段对应的小区/载波接收广播服务，因此，网络设备基于本实施例的能力信息进行调度，可以避免终端设备接收广播服务和进行单播和/或组播通信超过终端设备实际支持的基带能力和射频能力。
应说明的是，第五信息指示的是第三能力的作用，第三能力为终端设备对应于第一载波的能力，也即第五信息指示的是第三能力能够用于终端设备在第二频段对应的小区或载波接收广播服务，不是第三能力必须用于终端设备在第二频段对应的小区或载波接收广播服务，或者第三能力只能用于终端设备在第二频段对应的小区或载波接收广播服务，如下文指出，第三能力也可以用于终端设备在其他频段对应的小区或载波接收广播服务。应说明的是，第五信息指示终端设备基于第一频段组合进行载波聚合通信的情况下，终端设备在第二频段接收广播服务占用终端设备对应于第一载波的能力。在一种情况中，当终端设备基于另一频段组合(该频段组合包括第一频段，且第一频段包括第一载波)进行载波聚合通信的情况下，终端设备在第二频段接收广播服务并不占用终端设备对应于第一载波的能力。
可选的，终端设备对应于第一载波的能力用于终端设备在第二频段对应的小区或载波接收广播服务时，终端设备对应于第一载波的能力不支持终端设备在第一载波的服务小区进行通信。可选的，第二硬件资源用于终端设备在第二频段对应的小区或载波接收广播服务时，第二硬件能力无法用于终端设备在第一载波的服务小区进行通信，其中，第二硬件能力为终端设备在第一载波的服务小区进行通信占用的硬件能力。可选的，终端设备对应于第一载波的能力用于终端设备在第二频段对应的小区或载波接收广播服务时，终端设备不支持在第一载波的服务小区进行通信。由于终端设备无法同时在第二频段对应的小区或载波接收广播服务以及在第一载波的服务小区上进行通信，因此在终端设备需要在第二频段对应的小区或载波接收广播服务的情况下，终端设备需要停止在至少一个第一载波的服务小区上进行通信，以避免终端设备接收广播服务和在服务小区进行通信占用的硬件能力之和超出终端设备实际支持的总硬件能力。
如上文所述，终端设备对应于第一载波的能力用于终端设备在第二频段对应的小区或载波接收广播服务，在一种情况下，终端设备对应于第一载波的能力还用于终端设备在另外的一个或多个频段(与第二频段不同的频段)对应的小区接收广播服务，在该情况下，终端设备向第一网络设备发送的能力信息，还可以包括指示终端设备对应于第一载波的能力用于终端设备在另外的一个或多个频段对应的小区或载波接收广播服务信息。可以理解为，第五信息指示对应于第一载波的能力关联于一个频段列表，所述频段列表包括终端设备用于接收广播服务的频段，所述广播服务为终端设备在非服务小区上接收的广播服务。
当第一频段组合中的第一频段包括多个载波时，在一种情况下，终端设备对应于另外的一个或多个载波(第一频段组合中的第一频段中除第一载波的载波)的能力用于终端设备在第二频段和/或另外的 至少一个频段对应的小区接收广播服务，也即第四能力用于终端设备在第二频段对应的小区或载波接收广播服务，和/或第四能力用于终端设备在另外的至少一个频段对应的小区或载波接收广播服务，其中，第四能力为终端设备对应于第一载波集合中的载波的能力，第一载波集合中的载波为第一频段组合中的第一频段中除第一载波的载波。在该情况下，终端设备向第一网络设备发送的能力信息，还可以包括指示终端设备对应于另外的一个或多个载波(第一频段组合中的第一频段中除第一载波的载波)的能力用于终端设备在第二频段和/或另外的至少一个频段对应的小区或载波接收广播服务的信息。
示例性的，第一频段组合的第一频段还可以包括第三载波。能力信息还包括第七信息，第七信息指示终端设备对应于第三载波的能力用于终端设备在第二频段和/或第四频段对应的小区接收广播服务。其中，第一频段、第二频段和第四频段为不同的频段，第一载波和第三载波为不同的载波。在第一种情况中，第七信息指示终端设备对应于第三载波的能力用于终端设备在第二频段对应的小区或载波接收广播服务。在第二种情况中，第七信息指示终端设备对应于第三载波的能力用于终端设备在第四频段对应的小区上接收广播服务。在第三种情况中，第七信息指示终端设备对应于第三载波的能力用于终端设备在第二频段和第四频段对应的小区接收广播服务。
当第一频段组合包括多个频段时，在一种情况下，终端设备对应于第一频段组合中另外的一个或多个频段的载波用于终端设备在第二频段和/或另外的至少一个频段对应的小区接收广播服务，也即第五能力用于终端设备在第二频段对应的小区或载波接收广播服务，和/或第五能力用于终端设备在另外的至少一个频段对应的小区接收广播服务，其中，第五能力为终端设备对应于第二载波集合中的载波的能力，第二载波集合中的载波为第一频段组合中除第一频段之外的频段对应的载波。在该情况下，终端设备向第一网络设备发送的能力信息，还可以包括指示终端设备对应于第一频段组合中另外的一个或多个频段的载波用于终端设备在第二频段和/或另外的至少一个频段对应的小区或载波接收广播服务的信息。
示例性的，第一频段组合还包括第九频段，第九频段还包括第四载波。能力信息还包括第八信息，第八信息指示终端设备对应于第四载波的能力用于终端设备在第二频段和/或第四频段对应的小区上接收广播服务。在第四种情况中，第八信息指示终端设备对应于第四载波的能力用于终端设备在第二频段对应的小区或载波接收广播服务。第五种情况中，第八信息指示终端设备对应于第四载波的能力用于终端设备在第四频段对应的小区接收广播服务。第六种情况中，第八信息指示终端设备对应于第四载波的能力用于终端设备在第二频段和第四频段对应的小区接收广播服务。
上述实施例展示出频段组合中的载波与接收广播服务对应的频段的部分情况，下面将通过一个例子进行补充说明，第一频段组合的频段包括bandA、bandB和bandC，bandA包括CC1和CC2，bandB包括CC3和CC4，bandC包括CC5，终端设备支持在bnadQ、bnadP和bandE接收广播服务。
第一种情况中，第五信息指示终端设备对应于CC1的能力用于终端设备在bandQ对应的小区接收广播服务，第七信息指示终端设备对应于CC2的能力用于终端设备在bandQ对应的小区接收广播服务。
第二种情况中，第五信息指示终端设备对应于CC1的能力用于终端设备在bandQ对应的小区接收广播服务，第七信息指示终端设备对应于CC2的能力用于终端设备在bandP对应的小区接收广播服务。
第三种情况中，第五信息指示终端设备对应于CC1的能力用于终端设备在bandQ对应的小区接收广播服务，第七信息指示终端设备对应于CC2的能力用于终端设备在bandQ和bandP对应的小区接收广播服务。应说明的，终端设备对应于CC2的能力用于终端设备在bandQ和bandP对应的小区接收广播服务，一种情况为，终端设备对应于CC2的能力用于终端设备同时在bandQ和bandP对应的小区接收广播服务，另一种情况为，终端设备对应于CC2的能力用于终端设备在bandQ对应的小区接收服务，或者终端设备对应于CC2的能力用于终端设备在bandP对应的小区接收广播服务。
第四种情况中，第五信息指示终端设备对应于CC1的能力用于终端设备在bandQ对应的小区接收广播服务，第八信息指示终端设备对应于CC3的能力用于终端设备在bandQ对应的小区接收广播服务。
第五种情况中，第五信息指示终端设备对应于CC1的能力用于终端设备在bandQ对应的小区接收广播服务，第八信息指示终端设备对应于CC3的能力用于终端设备在bandP对应的小区接收广播服务。
第六种情况中，第五信息指示终端设备对应于CC1的能力用于终端设备在bandQ对应的小区接收广播服务，第八信息指示终端设备对应于CC3的能力用于终端设备在bandQ和bandP对应的小区接收广播 服务。应说明的，终端设备对应于CC3的能力用于终端设备在bandQ和bandP对应的小区接收广播服务，一种情况为，终端设备对应于CC3的能力用于终端设备同时在bandQ和bandP对应的小区接收广播服务，另一种情况为，终端设备对应于CC3的能力用于终端设备在bandQ对应的小区接收服务，或者终端设备对应于CC3的能力用于终端设备在bandP对应的小区接收广播服务。
可以理解的，虽然上述例子将各个情况拆开，但是实际的情况下是可以将不同的情况组合起来的。如将第三种情况和第六种情况组合起来，也即终端设备对应于CC1的能力用于终端设备在bandQ对应的小区接收广播服务，终端设备对应于CC2的能力用于终端设备在bandQ和bandP对应的小区接收广播服务，终端设备对应于CC3的能力用于终端设备在bandQ和bandP对应的小区接收广播服务。
应说明的是，上述例子仅仅是通过举例对频段组合中的载波与接收广播服务对应的频段之间的关系进行说明，并不应理解为对本方案的具体限定，频段组合中的载波与接收广播服务对应的频段之间的关系由终端设备的实际能力决定，终端设备向第一网络设备发送的能力信息可以指示如上述实施例所述的频段组合中的载波与接收广播服务对应的频段之间的关系。
应说明的是，如上述实施例，终端设备对应于第一频段组合中各频段中的各载波的能力可能均无法用于终端设备在某一频段(如上述实施例的bandE)对应的小区接收广播服务，但是终端设备对应于其他的频段组合中的频段中的载波的能力可能可以用于终端设备在该某一频段对应的小区接收广播服务。可选的，终端设备上报的能力信息除了包括第一频段组合的能力信息，还可以包括其他频段组合的能力信息。示例性的，能力信息还包括第五频段组合的能力信息，第五频段组合的频段属于终端设备支持的频段，第五频段组合的频段包括第十频段，第十频段包括第五载波，能力信息还包括第九信息，第九信息指示终端设备对应于第五载波的能力用于终端设备在第十一频段对应的小区接收广播服务。可以理解的，第十一频段可以是与第二频段相同的频段，也可以是与第二频段不同的频段。
如上述实施例所述，当终端设备在第一频段组合中进行单播/组播的通信的情况下，终端设备可以同时在bandE对应的小区/载波接收广播服务。也即终端设备在第一频段组合上的单播/组播通信只占用了部分的终端设备的能力，终端设备剩余的能力能够支持终端设备在bandE对应的小区/载波接收广播服务。示例性的，能力信息还可以包括指示信息，本实施例的指示信息的描述与图3对应的实施例的指示信息的描述类似，在此不再赘述。
在终端设备同时接收广播服务和在服务小区进行通信所占用的硬件能力之和超出终端设备实际支持的硬件能力的情况下，终端设备的服务小区对应的网络设备确定终端设备正在接收或者感兴趣接收广播服务的第五频段，然后根据能力信息确定与第五频段具有关联的第二载波(关联指的是终端设备对应于第二载波的能力用于终端设备在第五频段对应的小区接收广播服务)，指示终端设备停止在至少一个第二载波的服务小区的数据传输，则终端设备可以利用终端设备对应于该服务小区的能力接收广播服务，并利用剩余的服务小区进行通信，此时终端设备在服务小区进行通信和接收广播服务占用终端设备不同的硬件能力，可以避免终端设备在服务小区进行通信和接收广播服务占用的硬件能力之和超过终端实际支持的硬件能力。
应说明的，在终端设备在某一频段的服务小区进行通信的情况下，停止某一频段的服务小区通信，指的是停止在该某一频段的服务小区继续进行通信，包括停止在该某一频段的服务小区下行和上行的资源调度，停止发送数据和信令。在某一频段内的载波没有配置为服务小区，或者配置为了服务小区但该服务小区是去激活状态的辅小区的情况下，停止在某一频段的服务小区进行通信指的是，网络设备可以不将该某一频段的载波配置为服务小区，或不激活该某一频段上的辅小区。
在一个实施例中，第五信息包括第一载波与第二频段的第二关联信息，该第二关联信息指示终端设备对应于第一载波的能力用于终端设备在第二频段对应的小区或载波接收广播服务。
请继续参考图2，在一个实施例中，第五信息为第一频段组合下的第一频段下的第一载波关联的特性集包括第二频段标识，第二频段标识指示第二频段，第一载波关联的特性集包括第二频段标识则表示终端设备对应于第一载波的能力能够用于终端设备在第二频段对应的小区或载波接收广播服务。第二频段标识可以是第二频段对应的频率范围，或者是第二频段的频率范围的中心频率，也可以是与第二频段对应的编号，其中，不同的编号对应的频段不同。本实施例不对第二频段标识的形式作限定，只要根据 第二频段标识能唯一确定第二频段即可。
本实施例在确定终端设备对应于第一载波的能力能够用于终端设备在第二频段对应的小区或载波接收广播服务的情况下，通过在与第一频段组合的第一频段的第一载波关联的特性集中增加第二频段标识，并将该第一载波关联的特性集发送至第一网络设备，使得第一网络设备可以根据终端设备发送的能力信息确定第一频段组合的第一频段的第一载波和第二频段的关联关系，而在终端设备在第一频段组合进行载波聚合通信，且在第二频段对应的小区或载波接收广播服务时，与终端设备的服务小区对应的网络设备可以确定需要停止在至少一个第一载波的服务小区进行通信，以避免终端设备同时接收广播服务和在服务小区进行通信所占用的硬件能力之和超出终端设备实际支持的硬件能力。
同时，本申请实施例向网络设备发送的特性集组合对应的频段组合的频段并不包括接收广播服务对应的频段，仅是将与接收广播服务对应的频段的标识增加到对应的频段组合级的特性集组合中，相对于终端设备向网络设备发送第四频段组合(终端设备在服务小区进行通信的频段和接收广播服务的频段的频段组合)，并将第四频段组合的特性集组合发送给网络设备而言，本实施例没有增加新的频段组合(第四频段组合)的能力信息，信令开销较小。而且由于接收广播服务的频段可能为网络设备不支持的频段，若此时发送给终端设备的能力查询消息携带有过滤信息，网络设备将无法获得第四频段组合，也即无法避免终端设备同时接收广播服务和在服务小区进行通信占用的硬件能力之和不超过终端设备实际支持的硬件能力的情况，但是本实施例无需产生新的频段组合(第四频段组合)，因此即使能力查询消息携带有过滤信息，终端设备还是可以根据能力信息确定需要停止进行通信的服务小区，以避免终端设备同时接收广播服务和在服务小区进行通信占用的硬件能力之和超过终端设备实际支持的硬件能力。
请继续参考图5，在上述实施例的基础上，该通信方法还可以包括步骤503和步骤504，相对于上述实施例，终端设备除了向第一网络设备发送能力信息之外，终端设备在获知接收广播服务的频率信息的情况下，向第二网络设备发送第二信息，以使第二网络设备获知终端设备接收广播服务的频率，从而为第二网络设备可以根据能力信息确定终端设备需要停止的服务小区提供了条件。
步骤503，终端设备向第二网络设备发送第二信息。
应说明的由于图3对应的实施例与本实施例的能力信息包括的内容不同，因此本实施例与图3对应的实施例的第二信息有所区别，区别在于图3对应的实施例的第二信息还可以指示终端设备接收广播服务占用频段关联的能力或指示终端设备接收广播服务占用频段的载波关联的能力，但是本实施例的第二信息可以指示终端设备接收广播服务占用载波所属频段关联的能力或指示终端设备接收广播服务占用载波关联的能力，其中，占用载波关联的能力包括占用载波的数量。应说明的，第二信息指示终端设备接收广播服务占用载波所属频段关联的能力可以理解为，终端设备接收广播服务需要占用终端设备对应于整个频段的能力，如：终端设备接收第二频段上非服务小区的广播与第一载波所属频段上的单播/组播通信使用相同的射频通道，因此该射频通道要么用于在服务小区上的单播/组播通信，要么用于在非服务小区上的广播接收。当终端设备将该射频通道用于非服务小区上的广播接收时，如果网络设备在该频段上的任意一个载波上调度了单播/组播的数据，则终端设备无法在服务小区上接收到网络设备发送的单播/组播的数据，造成丢包，影响单播/组播的服务质量，在该情况下第二信息指示终端设备接收广播服务占用载波所属频段关联的能力。第二信息指示终端设备接收广播服务占用载波关联的能力可以理解为，第二信息指示终端设备接收广播服务需要占用终端设备对应于目标数量个载波的能力。对于步骤503的其他描述与图3对应的实施例的步骤303描述类似，在此不再赘述。
步骤504，第二网络设备接收第二信息。
对于步骤504的描述与图3对应的实施例的步骤304描述类似，在此不再赘述。
请继续参考图5，在上述实施例的基础上，该通信方法还可以包括步骤505，相对于上述实施例，步骤505具体阐述了第二网络设备如何根据能力信息以及第二信息确定终端设备需要停止进行通信的服务小区。
步骤505，第二网络设备根据能力信息以及第二信息确定第四信息。
针对终端设备接收广播服务和进行单播和/或组播发生冲突的情况，第四信息指示终端设备停止在第二服务小区的数据传输，第二服务小区为终端设备接收广播服务的第五频段关联的至少一个第二载波 的服务小区。应说明的，第二载波为终端设备与第二网络设备进行通信的载波，且终端设备对应于第二载波的能力用于终端设备接收第五频段的广播服务。第二网络设备根据第二信息确定终端设备接收广播的频段(第五频段)，根据能力信息确定与第五频段关联的载波(第二载波)，并指示终端设备停止在至少一个第二载波的服务小区进行通信。应说明的，根据能力信息以及第二信息可能可以确定出一个或j个第二载波，j为大于等于2的整数。根据上述实施例可知，第二信息还可以指示终端设备接收广播服务占用载波所属频段关联的能力或指示终端设备接收广播服务占用载波关联的能力，其中，占用载波关联的能力包括占用载波的数量。在第二信息指示终端设备接收广播服务占用载波所属频段关联的能力，且确定出j个第二载波的情况下，示例性的，第二网络设备可以按照预设规则选中j个第二载波中的一个。可选的，第二网络设备i个第二载波中信道质量最差的载波，指示终端设备停止在该信道质量最差的载波所属的频段进行通信。可选的，第二网络设备选中j个第二载波中重要程度最低的第二载波(称为第六载波)，指示终端设备停止在第六载波所属的第十二频段对应的所有服务小区进行通信，也即第二服务小区为第十二频段对应的所有服务小区，第十二频段包括第六载波。在第二信息指示终端设备接收广播服务占用载波关联的能力，且占用载波的数量为X，j≥X≥2，的情况下，第二网络设备指示终端设备停止在目标载波的服务小区进行通信，该目标载波为j个第二载波中按照重要程度从低到高的X个载波。
请继续参考图5，在该情况(终端设备接收广播服务和进行单播和/或组播发生冲突)中，该通信方法还可以包括步骤506，相对于上述实施例，第二网络设备在确定第四信息后向终端设备发送第四信息，以指示终端设备停止在第二服务小区进行通信。
步骤506，第二网络设备向终端设备发送第四信息。
第二网络设备向终端设备发送第四信息以指示终端设备停止在第二服务小区的数据传输，从而使得终端设备在第二服务小区进行数据传输占用的终端设备的能力被释放，终端设备通过释放的能力在第五频段对应的小区接收广播服务，通过其他的服务小区(未停止的服务小区)与第二网络设备进行通信，使得终端设备通过不同的能力接收广播服务和在服务小区与第二网络设备进行通信，避免终端设备同时接收广播服务和在服务小区与第二网络设备进行通信占用的硬件能力之和超过终端设备实际支持的硬件能力。
针对终端设备接收广播服务和进行单播和/或组播发生冲突的情况，第四信息指示网络设备不将第三小区配置为服务小区或激活，应说明的，在第三小区为非激活状态的辅小区的情况下，第四信息指示网络设备不激活该第三小区。应说明的，第三小区可以为一个或多个小区。第三小区对应的载波为终端设备接收广播服务的频率对应的频段的关联载波，也即第一终端设备对应于第三小区对应的载波的能力用于终端设备接收该频率的广播服务。
应说明的，图5对应的实施例的第一网络设备和第二网络设备为不同的网络设备，但是图5对应的通信方法也可以应用于第一网络设备和第二网络设备为同一设备网络的情况。
在一个实施例中，在终端设备接收广播服务对应的频率为目标运营商的频率范围的情况下，第二网络设备可以指示终端设备切换到包含该频率对应的频段的频段组合进行通信，其中，目标运营商为第二网络设备所属的运营商。
举例如下，目标运营商支持bandA、bandB、bandC以及bandE，终端设备支持的频段组合包括第六频段组合bandA+bandB+bandC以及第七频段组合bandA+bandB，其中，终端设备的能力信息指示终端设备对应于bandB的能力用于终端设备在bandE接收广播服务。终端设备在第六频段组合对应的频段与第二网络设备进行通信，第二信息指示终端设备在接收广播服务对应的频率为F，其中，F归属于bandE，也即bandE的频率范围包括F。
第二网络设备指示终端设备通过第七频段组合进行通信。此时，第一服务小区包括bandB的服务小区和bandC的服务小区，终端设备在bandE对应的小区接收广播服务，在bandA的服务小区进行单播通信。
在一个实施例中，第二网络设备在确定终端设备支持在主服务小区接收广播服务的情况下，将接收广播服务对应的频率F对应的服务小区配置为主服务小区。在一个实施例中，第二网络设备在确定终端 设备支持在辅小区中接收广播服务的情况下，将接收广播服务对应的频率F对应的服务小区配置为辅服务小区。应说明的，在终端设备既支持在主服务小区中接收广播服务，又支持在辅服务小区中接收广播服务，第二网络设备可以选择将接收广播服务的频率F对应的服务小区配置为主服务小区或辅服务小区。
应说明的，终端设备支持在多个频段上同时接收广播服务，下面将以终端设备在两个不同的频段上接收广播服务，终端设备发送的能力信息为第一实施例所述的能力信息为例对第二网络设备的单播调度进行说明，对于终端三个或三个以上的频段接收广播服务以及能力信息为第二实施例所述的能力信息的情况可以根据下述例子进行变形获得，本申请不再赘述。
终端设备在第六频段组合对应的服务小区与第二网络设备进行通信，第六频段组合包括bandA、bandB和bandC，第二信息指示终端设备在bandP和bandQ接收广播服务，第二信息还指示终端设备在bandP上接收广播服务占用频段关联的能力，第二信息还指示终端在bandQ上接收广播服务占用频段关联的能力，下述实施例所述的网络设备为终端设备的服务小区对应的网络设备。
在第一种情况中，能力信息指示终端设备对应于bandA的能力用于终端设备在bandQ对应的小区接收广播服务，或者终端设备在bandP对应的小区接收广播服务。网络设备指示终端设备停止在bandA的服务小区进行通信，终端设备可以选择终端设备在bandQ接收广播服务，还是在bandP接收广播服务。示例性的，终端设备在确定需要在bandQ接收广播服务以及在bandP上接收广播服务的情况下，通过终端设备的显示装置显示选择界面，响应于用户在选择界面的选择操作，确定终端设备在bandQ对应的小区接收广播服务，还是在bandP对应的小区接收广播服务。
在第二种情况中，能力信息指示终端设备对应于bandA的能力用于终端设备同时在bandQ和bandP对应的小区接收广播服务。网络设备指示终端设备停止在bandA的服务小区进行通信，终端设备可以同时在bandQ和bandP对应的小区接收广播服务。
在第三种情况中，能力信息指示终端设备对应于bandA的能力用于终端设备在bandP对应的小区接收广播服务，能力信息还指示终端设备对应于bandB的能力用于终端设备在bandQ接收广播服务。网络设备指示终端设备停止在bandA的服务小区和bandB的服务小区进行通信，终端设备可以实现在bandQ和bandP对应的小区接收广播服务。
