Description

一种终端通信能力发送、接收方法及装置
本申请要求在2018年10月29日提交中国专利局、申请号为201811270052.5、发明名称为“一种终端通信能力发送、接收方法及装置”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
本申请涉及信息技术领域，尤其涉及一种终端通信能力发送、接收方法及装置。
背景技术
目前，针对第五代移动通信技术(the 5th generation，5G)新无线(new radio，NR)定义了独立组网(standalone，SA)和非独立组网(non-standalone，NSA)这两大类组网模式。5GNR的独立组网模式，需要部署5G系统端到端的全新网络，包括新接入网(例如NR gNB)和新核心网(next generation core)，由5G系统独立承载完整的控制面(control-plane，CP)和用户面(user-plane，UP)，因此5G系统可以不依赖于长期演进(long term evolution，LTE)系统而工作，独立为用户提供通信服务。而在非独立组网模式下，5G系统需要依托现有的LTE系统，即，需要NR系统与LTE系统协调合作才能工作，例如采用多接入技术双连接(multi-RAT dual connectivity，MR-DC)的方式，NR基站和LTE基站同时与用户连接，共同为用户提供通信服务。在LTE系统中，可以将接入网部分称为演进的通用移动通信系统陆地无线接入(evolved UMTS terrestrial radio access，E-UTRA)，即LTE中的移动通信无线网络，E-UTRA某种程度上可以认为是LTE的空口技术。
具体的，独立组网的方式可能包括的组网方式：(1)、终端设备接入E-UTRA基站且E-UTRA基站连接第四代移动通信技术(the 4th generation，4G)核心网(简称：LTE独立组网方式)，(2)、终端设备接入增强的E-UTRA基站且增强的E-UTRA基站连接5G核心网(简称：eLTE独立组网方式)，(3)、终端设备接入NR基站且NR基站连接5G核心网(简称：NR独立组网方式)。另外，非独立组网的方式(终端设备同时接入E-UTRA基站和NR基站)可能包括的组网方式：(1)、E-UTRA基站为主基站，NR基站为辅基站，且E-UTRA基站连接4G核心网(简称：E-UTRA-NR双连接(E-UTRA-NR dual connectivity，EN-DC)组网方式)，(2)、E-UTRA基站为主基站，NR基站为辅基站，且E-UTRA基站连接5G核心网(简称：下一代E-UTRA-NR双连接(NG E-UTRA-NR dual connectivity，NGEN-DC)组网方式)，(3)、NR基站为主基站，E-UTRA基站为辅基站，且NR基站连接5G核心网(简称：NR-E-UTRA双连接(NR-E-UTRA dual connectivity，NE-DC)组网方式)。
目前，终端设备可能支持上述六种组网方式中的一种或多种组网方式，终端设备需要根据支持的组网方式向基站上报相关的通信能力信息，从而基站能够合理地调度终端设备。目前终端设备通过上报通信能力消息的方式上报通信能力信息，但是在LTE系统和NR系统中，一个消息的大小是有限制的，比如在LTE系统中，分组数据汇聚协议(packet data convergence protocol，PDCP))数据包最大包含8188byte(字节)，在NR系统中，PDCP 数据包最大包含9000byte。如果终端设备所上报的通信能力消息的字节数超过上述大小限制，则终端设备就不能够成功将通信能力消息发送至基站，也就无法与基站建立通信，造成通信失败。

如上介绍了本申请实施例涉及的一些概念，下面介绍本申请实施例的技术背景，以下结合图1进行详细说明。
图1是现有技术中终端设备向网络设备发送通信能力信息的示意性流程图，该通信能力信息可以为终端设备的无线接入通信能力信息，图1的步骤包括S11和S12，下面对这些步骤进行详细描述。需要说明的是，图1所述的步骤主要为终端设备和网络设备之间的信令流程，省略了网络设备和核心网之间的信令流程。
S11：网络设备向终端设备发送UE通信能力请求消息，则终端设备接收来自网络设备的UE通信能力请求消息，UE通信能力请求消息用于请求终端设备发送终端设备在某一(些)无线接入技术(radio access technology，RAT)中的通信能力信息。
例如，UE通信能力请求消息为UE通信能力查询(UE capability enquiry)消息。该UE通信能力请求消息可以指示一种或多种RAT(例如：E-UTRA技术，UTRA技术，NR技术，E-UTRA-NR中的一种或多种RAT)，表示请求该种RAT下的终端设备的通信能力信息。
对于一个处于连接态的终端设备，当核心网设备需要该终端设备的通信能力信息、且核心网设备没有储存该终端设备的通信能力信息时，核心网设备可以触发网络设备发起UE通信能力请求过程，也就是发起图1所示的流程，来请求终端设备的通信能力信息。在网络设备发起请求后，终端设备会向网络设备发送终端设备的通信能力信息，网络设备会将终端设备的通信能力信息进一步发送给核心网设备，以便网络设备或核心网设备根据终端设备的通信能力来配置或调度终端设备。其中，在不同的通信系统中，本文所涉及的核心网设备可以对应不同的设备，例如在4G系统中，本文所涉及的核心网设备可以是移动管理实体(mobility management entity，MME)，在5G NR系统中，本文所涉及的核心网设备可以是接入和移动性管理功能(access and mobility management function，AMF)。
S12：终端设备向网络设备发送UE通信能力消息，则网络设备接收来自终端设备的该UE通信能力消息。
该UE通信能力消息携带终端设备的无线接入通信能力信息，例如，在网络设备发送的UE通信能力请求消息中包括了某一(些)RAT，若终端设备支持该一(些)RAT，则终端设备需要在UE通信能力消息中包括该一(些)RAT的通信能力容器(container)，该一(些)RAT的container包括了该一(些)RAT的通信能力信息，并且将container中的RAT类型参数设置成该种RAT。例如：在UE通信能力请求消息中请求了E-UTRA技术的通信能力信息，若终端设备支持E-UTRA技术，终端设备需要在UE通信能力消息中包括E-UTRA技术的通信能力信息，并且将UE通信能力消息中的RAT类型参数设置成E-UTRA。
其中，UE通信能力消息例如通过UE通信能力信息(UE capability information)消息实现，可以是专门用于上报终端设备的通信能力信息的消息，在UE通信能力消息中可以包含该终端设备的至少一种RAT的通信能力信息。终端设备的无线接入通信能力信息例如可以包括：PDCP参数、物理层参数、射频参数、测量参数等，这些通信能力参数具体对应的通信能力例如频带组合(band combination)、支持的载波聚合带宽级别(ca-bandwidthclass)、调制编码方式(modulation and coding scheme)等通信能力信息。上述通信能力参数或通信能力信息为示例的通信能力参数或通信能力信息，具体完整的通信能力信息本申请实施例中，在此不赘述。
网络设备在接收UE通信能力消息之后，可以根据无线接入通信能力信息的具体的参数配置终端设备的PDCP配置、物理层配置、射频配置、测量配置等，保证终端设备的配置能够满足终端设备自身的通信能力，即，终端设备能够在网络设备的配置下正常工作。
如图1所示的流程中所述，网络设备向终端设备发送UE通信能力请求消息，请求终端设备的一种或多种RAT的通信能力信息，终端设备需要在UE通信能力消息中上报终端设备的这一种或多种RAT的通信能力信息。终端设备在向网络设备(例如基站)发送终端设备的通信能力信息时，是根据UE通信能力请求消息中的RAT，将通信能力信息放在相应的通信能力(capability)字段中，例如，终端设备会将终端设备在E-UTRA下的通信能力信息放在UE-EUTRA-capability字段中，将在NR下的通信能力信息放在UE通信能力请求消息所包括的UE-NR-capability字段中，将在MR-DC下的通信能力信息放在UE通信能力请求消息所包括的UE-MRDC-capability字段中，然后将包含上述通信能力字段的通信能力信息发送至网络设备。
具体地，各通信能力字段包含于各通信能力容器(capability container)字段中，例如，终端设备会将终端设备在E-UTRA下的通信能力信息放在ueCapabilityRAT-container字段中，且该ueCapabilityRAT-container的RAT类型参数设置成E-UTRA。终端设备会将终端设备在NR下的通信能力信息放在ueCapabilityRAT-container字段中，且该ueCapabilityRAT-container的RAT类型参数设置成NR。终端设备会将终端设备在MR-DC下的通信能力信息放在ueCapabilityRAT-container字段中，且该ueCapabilityRAT-container的RAT类型参数设置成MR-DC。各通信能力容器字段组合成通信能力容器列表(capability container list)字段，即通信能力容器列表字段包括各个RAT的通信能力容器(capability container)字段，最终通信能力容器列表字段包含于终端上报通信能力的通信能力信息字段(UECapabilityInformation-IE)中，通过UE通信能力消息(UECapabilityInformation)上报给基站。
其中，通信能力字段的信令设计如表1所示，表1中示例性地以UE-EUTRA-capability字段说明。

具体来说，通信能力字段指示某一种RAT的通信通信能力，通信能力容器字段指示某一种RAT的通信通信能力和RAT的类型，通信能力容器列表字段指示多个RAT的通信通信能力，是由多个RAT的通信能力容器字段组合而成的，通信能力容器列表字段包含在通信能力信息字段中，通信能力信息字段通过通信能力消息发送给网络设备。

目前，独立组网的方式包括几种具体的方式，分别为LTE独立组网方式、eLTE独立组网方式和NR独立组网方式，其中，LTE独立组网方式请参考图2A，是指终端设备接入E-UTRA基站且E-UTRA基站连接4G核心网的组网方式，eLTE独立组网方式请参考图2B，是指终端设备接入增强的E-UTRA基站且增强的E-UTRA基站连接5G核心网的组网方式，NR独立组网方式请参考图2C，是指终端设备接入NR基站且NR基站连接5G核心网的组网方式。非独立组网的方式也包括几种具体的方式，分别为EN-DC组网方式、NGEN-DC组网方式和NE-DC组网方式，其中，EN-DC组网方式请参考图2D，是指E-UTRA基站为主基站，NR基站为辅基站，且E-UTRA基站连接4G核心网的组网方式，NGEN-DC组网方式请参考图2E，是指E-UTRA基站为主基站，NR基站为辅基站，且E-UTRA基站连接5G核心网的组网方式，NE-DC组网方式请参考图2F，是指NR基站为主基站，E-UTRA基站为辅基站，且NR基站连接5G核心网的组网方式。
可能有一类终端设备，可能支持上述六种组网方式中的多种，终端设备需要根据所支持的组网方式向基站上报相关的能力信息。例如终端设备可以通过S12中的UE能力消息来向网络设备上报终端设备的能力信息，在该UE能力消息中包含三个部分：E-UTRA能力信息(携带在UE-EUTRA-capability字段中)、NR能力信息(携带在UE-NR-capability字段中)以及MR-DC能力信息(携带在UE-MRDC-capability字段中)，如果该终端设备所上报的能力消息的字节数超过上限值，那么终端设备就不能够成功将能力消息发送至网络设备，因此就会造成通信失败。
鉴于此，在本申请实施例中，终端设备可以通过将终端设备的能力信息进行拆分，将拆分后的多个能力信息分别承载在不同的消息中，然后发送至网络设备，因拆分之后的消息的大小均小于上限值，所以网络设备能够成功接收能力消息。
值得说明的是，本申请实施例提供的技术方案可应用于终端设备与一个网络设备连接的场景中，或者也可用于MR-DC场景中，或者还可以用于其他的场景中，具体的不作限制。
请参考图3A，为本申请实施例的一种应用场景。图3A中包括网络设备和终端设备，终端设备与一个网络设备连接。当然图3A中的终端设备的数量只是举例，在实际应用中，网络设备可以为多个终端设备提供服务，多个终端设备中的全部终端设备或者部分终端设备都可以采用本申请实施例提供的方法向网络设备发送通信能力信息。

请参见图3B，为本申请实施例的另一种应用场景，图3B所示的场景可理解为MR-DC场景。在图3B中包括两个网络设备以及一个终端设备，这两个网络设备分别为第一网络设备和第二网络设备，第一网络设备例如为终端设备的主网络设备，第二网络设备是终端设备的辅网络设备，这两个网络设备例如均为接入网设备，例如基站，那么主网络设备也就是主基站，辅网络设备也就是辅基站。其中，第一网络设备例如工作在E-UTRA系统中，第二网络设备例如工作在NR系统中，也就是，第一网络设备例如为E-UTRA网络设备，第二网络设备例如为NR网络设备，或者，第一网络设备例如工作在NR系统中，第二网络设备例如工作在E-UTRA系统中，也就是，第一网络设备例如为NR网络设备，第二网络设备例如为E-UTRA网络设备。其中，终端设备同时连接到这两个网络设备，终端设备与这两个网络设备均可以通信。
图3B中的网络设备可以为接入网设备(例如基站)。其中，本申请实施例所应用的场景中，接入网设备可以是4G系统中的eNB，或者可以是5G系统中的增强型eNB，或者可以是5G系统中的gNB。另外图3B中未画出核心网部分，本申请实施例所应用的场景中，核心网可以是4G系统中的4G核心网，或者是5G系统中的5G核心网。如果第一网络设备是主网络设备，那么是第一网络设备连接核心网，如果第二网络设备是主网络设备，那么是第二网络设备连接核心网。
下面结合附图介绍本申请实施例提供的技术方案。

为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端设备为例。因为本文是以将本实施例提供的技术方案应用在图3A或图3B所示的网络架构为例，那么在将本实施例应用在图3A所示的网络架构时，下文中所述的网络设备可以是图3A所示的网络架构中的网络设备，下文中所述的终端设备可以是图3A所示的网络架构中的终端设备，而在将本实施例应用在图3B所示的网络架构时，下文中所述的网络设备可以是图3B所示的网络架构中的任意一个网络设备，例如为图3B所示的网络架构中的第一网络设备，下文中所述的终端设备可以是图3B所示的网络架构中的终端设备。
图4为本申请实施例提供的一种终端通信能力信息发送、接收方法的交互流程图，具体包括如下步骤：
S41、网络设备向终端设备发送第一消息。
其中，第一消息用于请求所述终端设备的K种无线接入技术RAT的通信能力信息，K为大于等于1的正整数。
S42、终端设备根据第一消息，确定N个通信能力信息。
其中，这N个通信能力信息组成所述终端设备的K种RAT的总通信能力信息。
S43、终端设备向所述网络设备发送K个消息，这K个消息分别是第二消息至第K消息，K个消息中每个消息分别承载了N个通信能力信息的部分信息，这K个消息中承载了全部N个通信能力信息，N和K为大于等于2的正整数，K小于等于N。
S44，网络设备根据接收的K个消息确定终端的通信能力信息。
也就是网络设备将K个消息中的N个通信能力信息组合成终端的总通信能力信息。
在S41中，网络设备向终端设备发送的第一消息可以通过图1所示的流程中的UE通信能力请求(例如UE capability enquiry)消息实现。在S43中，终端设备向所述网络设备发送的K个消息可以通过图1所示的流程中的K个UE通信能力消息(例如UE capability information)实现。
其中，在步骤S42中，N个通信能力信息中每个通信能力信息的具体内容是根据终端设备所拆分的字段确定的，包括但不限于如下几种不同的实现：
第一种可能的实现方式，终端设备将所述终端设备的K种RAT的通信能力容器字段拆分成所述N个能力信息，则N个通信能力信息中的一个能力信息包括能力容器字段的部分或者全部，所述能力容器字段指示所述终端设备的K种RAT中的任意一种RAT的能力信息。
例如，网络设备所发送的第一消息用于请求E-UTRA技术、NR技术和MR-DC技术的通信能力信息，终端设备根据第一消息，会将终端设备在E-UTRA下的通信能力信息放在E-UTRA类型的ueCapabilityRAT-container字段中，然后将承载ueCapabilityRAT-container字段的第二消息发送至网络设备，接着终端设备将在NR下的通信能力信息放在NR类型的ueCapabilityRAT-container字段中，并将承载ueCapabilityRAT-container字段的第三消息发送至网络设备，最后终端设备将在MR-DC下的通信能力信息放在MR-DC类型的ueCapabilityRAT-container字段中，并将承载ueCapabilityRAT-container字段的第四消息发送至网络设备。
再比如，网络设备所发送的第一消息用于请求E-UTRA技术、NR技术和MR-DC技术的通信能力信息，终端设备根据第一消息，会将终端设备在E-UTRA下的通信能力信息放在E-UTRA类型的ueCapabilityRAT-container字段中，然后将ueCapabilityRAT-container字段拆分成第一通信能力信息和第二通信能力信息，并将承载第一通信能力信息的第二消息发送至网络设备，以及将承载第二通信能力信息的第三消息发送至网络设备。进一步地，终端设备将在NR下的通信能力信息放在NR类型的ueCapabilityRAT-container字段中，然后将ueCapabilityRAT-container字段拆分成第三通信能力信息和第四通信能力信息，并将承载第三通信能力信息的第四消息发送至网络设备，以及将承载第四通信能力信息的第五消息发送至网络设备。进 一步地，终端设备将在MR-DC下的通信能力信息放在MR-DC类型的ueCapabilityRAT-container字段中，然后将ueCapabilityRAT-container字段拆分成第五通信能力信息和第六通信能力信息，并将承载第五通信能力信息的第六消息发送至网络设备，以及将承载第六通信能力信息的第七消息发送至网络设备。
需要说明的是，本申请实施例并不限定终端设备向网络设备所发送的K个消息中每个消息具体包括的通信能力信息的数目，可以是K个消息中的第二消息包括一个通信能力信息，而K个消息中的第三消息中包括两个通信能力信息，甚至K个消息中的第四消息中包括一个通信能力信息的一部分。假设协议规定终端向网络设备发送的消息的字节数为100字节，如果终端设备将E-UTRA类型的ueCapabilityRAT-container字段拆分成第一通信能力信息和第二通信能力信息，第一通信能力信息是10字节，第二通信能力信息是10字节，另外，终端设备将NR类型的ueCapabilityRAT-container段拆分成第三通信能力信息和第四通信能力信息，第三通信能力信息是90字节，第四通信能力信息是90字节，这样，终端设备就可以将第一通信能力信息和第三通信能力信息承载在第二消息中，然后将第二消息发送网络设备，接着，终端设备将第二通信能力信息和第四通信能力信息承载在第三消息中，然后将第三消息发送至网络设备。换句话说，本申请实施例并不限定N个通信能力信息在K个消息中的排列组合方式。
第二种可能的实现方式，终端设备将所述终端设备的K种RAT的通信能力字段拆分成所述N个通信能力信息，则N个通信能力信息中的一个能力信息包括通信能力字段的部分或者全部，所述通信能力字段指示所述终端设备的K种RAT中的任意一种RAT的通信能力信息。
例如，网络设备所发送的第一消息用于请求E-UTRA技术、NR技术和MR-DC技术的通信能力信息，终端设备根据第一消息，会将终端设备在E-UTRA下的通信能力信息放在UE-EUTRA-capability字段中，然后将承载UE-EUTRA-capability字段的第二消息发送至网络设备，接着终端设备将在NR下的通信能力信息放在UE-NR-capability字段中，并将承载UE-NR-capability字段的第三消息发送至网络设备，最后终端设备将在MR-DC下的通信能力信息放在UE-MRDC-capability字段中，并将承载UE-MRDC-capability字段的第四消息发送至网络设备。
再比如，网络设备所发送的第一消息用于请求E-UTRA技术、NR技术和MR-DC技术的通信能力信息，终端设备根据第一消息，会将终端设备在E-UTRA下的通信能力信息放在UE-EUTRA-capability字段中，然后将UE-EUTRA-capability字段拆分成第一通信能力信息和第二通信能力信息，并将承载第一通信能力信息的第二消息发送至网络设备，以及将承载第二通信能力信息的第三消息发送至网络设备。进一步地，终端设备将在NR下的通信能力信息放在UE-NR-capability字段中，然后将UE-NR-capability字段拆分成第三通信能力信息和第四通信能力信息，并将承载第三通信能力信息的第四消息发送至网络设备，以及将承载第四通信能力信息的第五消息发送至网络设备。进一步地，终端设备将在MR-DC下的通信能力信息放在UE-MRDC-capability字段中，然后将UE-MR-DC-capability字段拆分成第五通信能力信息和第六通信能力信息，并将承载第五通信能力信息的第六消息发送至网络设备，以及将承载第六通信能力信息的第七消息发送至网络设备。
第三种可能的实现方式，终端设备将所述终端设备的K种RAT的通信容器列表拆分成所述N个通信能力信息，则N个通信能力信息中的一个能力信息包括通信能力容器列表字段的部分，所述通信能力容器列表字段指示所述终端设备的K种RAT的总通信能力信息。
例如，网络设备所发送的第一消息用于请求E-UTRA技术、NR技术和MR-DC技术的通信能力信息，终端设备根据第一消息，会将终端设备在E-UTRA下的通信能力信息、在NR下的通信能力信息以及在MR-DC下的通信能力信息放在通信能力容器列表(UE-CapabilityRAT-containerList或capability container list)字段中，然后终端设备将通信能力容器列表字段拆分成N个通信能力信息，终端设备可以将每个通信能力信息分别放在一个消息中发送至网络设备，也可以将每两个通信能力信息放在一个消息中发送至网络设备，也可以将某个RAT通信能力信息的一部分放在一个消息中发送至网络设备，并将这个RAT通信能力信息的另外一部分放在另外一个消息中发送至网络设备，在此本申请实施例并不限定具体的组合形式。
第四种可能的实现方式，终端设备将所述终端设备的K种RAT的通信能力信息字段拆分成所述N个通信能力信息，则N个通信能力信息中的一个能力信息包括通信能力信息字段的部分，所述通信能力信息字段指示所述终端设备的K种RAT的总通信能力信息。
例如，网络设备所发送的第一消息用于请求E-UTRA技术、NR技术和MR-DC技术的通信能力信息，终端设备根据第一消息，会将终端设备在E-UTRA下的通信能力信息、在NR下的通信能力信息以及在MR-DC下的通信能力信息放在通信能力信息字段(UECapabilityInformation-IE)中，然后终端设备将通信能力信息字段拆分成N个通信能力信息，终端设备可以将每个通信能力信息分别放在一个消息中发送至网络设备，也可以将每两个通信能力信息放在一个消息中发送至网络设备，在此本申请实施例并不限定具体的组合形式。
第五种可能的实现方式，终端设备将所述终端设备的通信能力消息按照字节拆分成K个消息，一个通信能力信息是通信能力消息的部分，通信能力消息指示所述K种RAT的总通信能力信息。
例如，网络设备所发送的第一消息用于请求E-UTRA技术、NR技术和MR-DC技术的通信能力信息，终端设备根据第一消息，会将终端设备在E-UTRA下的通信能力信息、在NR下的通信能力信息以及在MR-DC下的通信能力信息放在通信能力消息(UECapabilityInformation)中，然后终端设备将通信能力消息中的信息拆分成N个通信能力信息，终端设备可以将每个通信能力信息分别放在一个消息中发送至网络设备，也可以将每两个通信能力信息放在一个消息中发送至网络设备，在此本申请实施例并不限定具体的组合形式。
值得说明的是，N个通信能力信息究竟采用如上五种实现方式中的哪一种，可以通过协议规定，或者可以由网络设备预先配置，或者可以由终端设备自行确定并告知网络设备。另外，除了以上五种实现方式之外，N个通信能力信息还可以通过拆分其他字段的方式实现，本申请实施例不做限制。
在一种可能的设计中，终端设备在确定终端设备的总通信能力信息的大小超过上 限值时，将该总通信能力信息拆分成N个通信能力信息。也就是说，当终端设备确定总通信能力信息太大，如果放在一个消息中会超出上限值，这时终端设备才对总通信能力信息进行拆分，得到N个通信能力信息。
具体来说，针对上述第一种实现方式，终端设备对通信能力容器字段的拆分可以存在如下几种信令设计方案。
实施例一，
终端设备通过对通信能力容器字段(UE-CapabilityRAT-Container)进行分段，生成N个通信能力信息，在本实施例中，改变了通信能力消息的结构，新增了版本号为vxyz的UE-CapabilityRAT-ContainerList-vxyz以及UE-CapabilityRAT-Container-vxyz，详细介绍见下文信令设计中的加粗字体部分。
具体信令设计为：
