Description

针对组播业务的配置管理方法及相关产品 技术领域
本发明涉及通信技术领域，尤其涉及一种针对组播业务的配置管理方法及相关产品。
背景技术
车联网系统是基于长期演进(Long Term Evaluation，LTE)-终端到终端(Device to Device，D2D)的一种侧行链路传输技术(Sidelink,SL)，与传统的LTE系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用终端到终端直接通信的方式，未来在自动驾驶等应用场景中，用户对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。

具体实施方式
下面将结合附图对本发明实施例中的技术方案进行描述。
设备到设备通信(Device-to-Device,D2D)是基于D2D的一种侧行链路传输技术(Sidelink,SL)，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用终端到终端直接通信的方式，具有更高的频谱效率以及更低的传输时延。在第三代合作伙伴计划(Third Generation Partner Project，3GPP)版本14(Rel-14)中对车联网技术进行了标准化，定义了两种传输模式：模式A和模式B。
模式A：请参阅图1A，终端的传输资源是由基站分配的，终端根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源；基站通过下行(Downlink，DL)控制信令分配侧行链路传输资源。
模式B：请参阅图1B，终端采用侦听(sensing)和预留(reservation)的传输方式。终端在资源池中通过侦听的方式获取可用的传输资源集合，终端从该集 合中随机选取一个资源进行数据的传输。由于车联网系统中的业务具有周期性特征，因此终端通常采用半静态传输的方式，即终端选取一个传输资源后，就会在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。终端会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他终端可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用，达到降低资源冲突的目的。
在3GPP中，D2D分成了多个不同的阶段进行研究，其中：
在版本12/13(Rel-12/13)中设备到设备通信，是针对邻近服务(Proximity based Service,ProSe)的场景进行的研究，主要针对公共安全类的业务。其中，对于非连续收发参数的配置是基于预配置，或者是网络配置的基于网络或者终端UE传播的定时参考信号，相互通信的UE之间只有配置了相同的非连续收发参数，即基于相同的预配置、网络配置，UE间对于非连续收发参数的配置相同，才能实现UE间的数据收发。
在版本14/15(Rel-14/15)中，在车联网系统，即针对新空口NR-车辆到其他设备(Vehicle to Everything，V2X)的车车通信的场景进行了研究，其主要面向相对高速移动的车车、车人通信的业务，其中，在车联网环境中，汽车类终端有固定的电源输入，所以对于非连续收发中的接收模式的配置，没有加以考虑，即假设汽车类终端一直处于连续接收的状态；而，手持类终端没有固定的电源接入，所以原理上需要考虑非连续接收，但是由于非连续接收和车联网低时延的要求相违背，在车联网环境中手持类终端并没有实现数据接收功能，而只是处于单向发送的状态，依靠汽车类终端的接收功能完成数据单向传递。
在版本14(Rel-14)中，针对可穿戴类设备通过手机接入网络的场景进行了研究，其主要面向是低移动速度以及低功率接入的场景。在可穿戴设备的场景中，对于可穿戴设备与手机间通信时所使用的非连续数据收发的模式进行了研究，使用的方式为：基站通过中继UE配置远端UE的非连续收发参数。当远端UE收到基站的配置的非连续收发参数之后，远端UE通过使用非连续收发参数与中继UE进行通信，本发明实施例所涉及到的终端可以包括各种具有无限通信功能的手持设备、车载设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)、路边单元(Roadside Unit，RSU)等等。为方便描述，上面提到的终端统称为终端。
针对D2D/V2X的连接管理方面：
在ProSe系统中，3GPP定义了基于针对终端到终端的连接管理的(PC5-Signaling,PC5-S)协议，其包括但不限于：
-连接的建立与释放；
-连接的安全参数配置；
-连接的信道质量监控；
在LTE-V2X中，由于主要针对的是广播业务，终端与终端之间没有连接的概念，3GPP没有定义连接管理机制，且在NR-V2X中，由于需要考虑单播和组播业务，终端之间存在连接的概念，如何进行连接管理机制的设计，包括使用PC5-Signaling在非接入层进行管理和/或使用PC5-RRC信令在接入层进行管理的方案设计，是需要解决的问题。
针对上述问题，本申请提出一种针对组播业务的配置管理方法，以实现终端与终端之间的通信连接的配置管理。下面进行具体说明。
请参阅图2A，图2A是本发明实施例提供的一种针对组播业务的配置管理方法，应用于通信系统如LTE-V2X系统中的第一终端，该方法包括：
步骤201，所述第一终端向至少一个第二终端发送针对第一组播业务的第一配置信息，其中，所述第一配置信息用于配置所述至少一个第二终端中的目标第二终端。
其中，第一组播业务关联所述至少一个第二终端，且，针对该第一组播业务目标第二终端需要根据第一配置信息进行配置，而，至少一个第二终端中除所述目标第二终端之外的第二终端需要不同于第一配置信息的配置信息进行配置，例如，第二终端A需要通过第二配置信息进行配置，第二终端B需要通过第三配置信息进行配置等，在此不做限定。
其中，第一组播业务，例如可以是视频业务、音频业务等，在此不做限定。
其中，第一配置信息包括多种指示信息，其中，该第一配置信息包括但不限于测量类配置信息、安全加密类配置信息、针对协议栈的配置信息等(例如分组数据聚合协议(Packet Data Convergence Protocol,PDCP)层、无线链路控制(Radio Link Control,RLC)层、媒体接入控制(Media Access Control,MAC)层的配置信息)。
其中，当上述至少一个第二终端中的目标第二终端接收到该第一配置信息时，根据第一配置信息进行配置控制操作，以实现第一终端与目标第二终端之间第一组播业务的传输。
可以看出，本发明实施例中，第一终端向至少一个第二终端发送针对第一组播业务的第一配置信息，其中，所述第一配置信息用于配置所述至少一个第二终端中的目标第二终端。可见，第一终端在发送组播业务时，可以单独配置至少一个第二终端中的目标第二终端，而不需要给所有的第二终端集体配置相同的配置，实现了单个终端到单个终端的配置，有利于提升终端配置的灵活性和针对性，提升配置管理效率。
在一个可能的示例中，所述第一组播业务关联设备群组内的多个终端的多个配置信息，所述多个配置信息包括所述第一配置信息，所述多个配置信息中的任意两个配置信息互不相同，所述设备群组为所述第一组播业务的设备群组。
其中，所述设备群组包括第一组播业务关联的多个终端，且该多个终端包 括上述至少一个第二终端。
其中，所述多个配置信息为针对多个终端中不同终端的不同配置信息，例如，包括上述第二配置信息、第三配置信息。
可见，本示例中，第一终端可以将第一组播业务关联的多个配置信息分别发送给设备群组内的不同的终端进行配置，提升了配置的灵活性，实现了第一组播业务在设备群组内的播放。
在一个可能的示例中，所述至少一个第二终端包括一个第二终端；所述第一配置信息通过单播连接传输。
其中，单播连接传输为第一终端与第二终端之间的点到点连接传输，即该第一配置信息从第一终端通过单播连接传输到第二终端。
可见，本示例中，第一终端通过单播连接传输将第一配置信息发送给第二终端，可以提升第一配置信息的针对性，使第二终端可以及时了解到第一配置信息与自身的关联性。
在这个可能的示例中，其特征在于，所述单播连接传输包括以下传输方式中的至少一种：
通过与所述第一终端的标识和/或所述目标第二终端的标识相关联的层2地址或媒体接入控制层地址传输；
通过与所述第一终端和所述目标第二终端之间的单播数据承载和/或信令承载传输。
其中，层2包括MAC层，和物理层。
可见，本示例中，第一终端通过上述两种传输方式中的任意一种或者多种传输方式可以准确将第一配置信息传输至第二终端，实现第一终端与第二终端之间的单播连接传输，提升传输的准确性，降低传输时延。
在一个可能的示例中，所述第一配置信息与所述第一组播业务的对应关系通过以下至少一种方式指示：
第一配置信息包含第一组播业务的相关标识；
第一配置信息包含第一组播业务相关联的层2地址或媒体接入层地址；
第一配置信息通过与第一组播业务相关联的层2地址或媒体接入控制层地址传输；
第一配置信息通过与第一组播业务相关联的单播数据承载和/或信令承载传输。
其中，第一组播业务的相关标识为可以使第二终端确定第一组播业务的多种标识，例如，可以为第一组播业务的业务标识，或者可以是第一组播业务的ID标识等，在此不做限定。
其中，第二终端可以通过上述任意一种或者多种指示方式确定第一组播业务，举例而言，当前第二终端正在进行两个组播业务，分别是第一组播业务和第二组播业务，则第二终端可以通过上述任意一种或者多种指示方式确定第一 配置信息对应的第一组播业务，同样的，第二终端可以确定第二组播业务对应的配置信息。
其中，第一配置信息通过与第一组播业务相关联的层2地址或媒体接入控制层地址传输，或者第一配置信息通过与第一组播业务相关联的单播数据承载和/或信令承载传输是指，在第一配置信息传输的过程中，在相应的协议层的报文头中添加与第一组播业务相关联的信息，该信息可以是层2地址、媒体接入控制层地址、单播数据承载或单播信令承载等。
可见，本示例中，第一终端通过在第一配置信息中添加与第一组播业务相关的标识或者层2地址或者媒体接入层地址，或者通过与第一组播业务相关联的层2地址、媒体接入层地址、单播数据承载和/或信令承载的方式传输第一配置信息的方式，使第二终端在接收到第一配置信息时，准确获知第一配置信息对应的第一组播业务，避免第二终端在同时进行多个组播业务时，配置信息的混乱，提升组播业务的配置的准确性。
在一个可能的示例中，所述至少一个第二终端包括多个第二终端；所述第一配置信息通过组播连接传输。
其中，组播连接传输为在第一终端与多个第二终端中的每个第二终端之间实现点对点的网络连接，即实现第一终端与多个第二终端的点对多点的网络连接传输。
可见，本示例中，第一终端通过组播连接传输的方式传输第一配置信息，使目标第二终端可以通过该组播连接准确确定第一组播业务的信息，而不需要第一终端在第一配置信息中添加第一组播业务的关联信息，有利于提升第一组播业务播放的准确性，以及降低第一配置信息的数据量。
在这个可能的示例中，所述组播连接传输包括以下传输方式中的至少一种：
第一配置信息通过与第一组播业务标识相关联的层2地址或媒体接入控制层地址传输；
第一配置信息通过与用于第一组播业务相关联的组播数据承载和/或信令承载传输。
其中，第一配置信息通过与第一组播业务标识相关联的层2地址或媒体接入控制层地址传输，或者第一配置信息通过与用于第一组播业务相关联的组播数据承载和/或信令承载传输是指，在组播连接传输第一配置信息的过程中，在相应的协议层的报文头中添加与第一组播业务相关联的信息，该信息可以是层2地址、媒体接入控制层地址、组播数据承载或组播信令承载等。
可见，本示例中，第一终端通过上述两种传输方式中的任意一种或者多种传输方式可以准确指示组播连接传输的第一组播业务，提升第二终端接收到第一配置信息时确定第一组播业务的及时性和准确性。
在一个可能的示例中，所述第一配置信息与所述目标第二终端之间的对应关系通过以下至少一种方式指示：
第一配置信息包含所述目标第二终端的相关标识；
第一配置信息包含所述目标第二终端相关联的层2地址或媒体接入层地址。
其中，目标第二终端的相关标识可以是多种多样的，例如可以是IP地址标识、ID标识等，在此不做限定。
举例而言，第一终端通过组播连接传输的多个第二终端中包括目标第二终端和第二终端A，那么当目标第二终端和第二终端A均接收到第一配置信息时，目标第二终端和第二终端A可以通过第一配置信息中的上述指示信息确定第一配置信息为目标第二终端的配置信息而非第二终端A的配置信息，那么目标第二终端则会根据该第一配置信息进行配置操作，而，第二终端A则不会根据第一配置信息进行配置操作。
可见，本示例中，第一终端在通过组播连接传输方式传输第一配置信息时，在第一配置信息中添加第一配置信息对应的目标第二终端的相关标识或者相关联的层2地址或媒体接入层地址等，有利于提升目标第二终端准确确定第一配置信息与自身的关联性，提升配置控制的准确性。
在一个可能的示例中，其特征在于，所述第一配置信息通过媒体接入层控制单元MAC CE或者无线资源控制RRC传输。
其中，第一配置信息属于所传输信息的负载payload部分的内容，此处限定的是payload部分内容的传输是通过媒体接入层控制单元MAC CE或者无线资源控制RRC传输，而上述的第一配置信息通过与第一组播业务标识相关联的层2地址或媒体接入控制层地址传输，或第一配置信息通过与用于第一组播业务相关联的组播数据承载和/或信令承载传输等方式是属于限定传输报文头部分的内容，两者相互独立。
在一个可能的示例中，所述第一配置信息用于配置所述第二终端的以下至少一层的配置：
服务数据适配协议SDAP层，分组数据聚合协议PDCP层，无线链路控制RLC层，媒体接入控制MAC层，物理PHY层。
在一个可能的示例中，所述PHY层的配置包含可用资源的配置。
可见，本示例中，第一终端发送的第一配置信息中针对不同的第二终端的可以给出不同的可用资源集合，使不同的第二终端根据配置信息配置后使用的资源相互独立，以减少干扰。
下面结合具体应用场景，对本发明实施例进行具体说明。
场景1：如图2B所示，在单播连接传输的情况下，第一终端通过与第一终端和/或第二终端标识相关联的层2地址或者通过与第一终端和第二终端之间的单播数据承载和/或信令承载传输的单播连接传输方式给目标第二终端发送第一配置信息，由于是通过单播连接传输，即第一终端仅将第一配置信息发送给目标第二终端，因此，目标第二终端可以通过单播连接确定第一配置信息是 发送给自己的，因此，针对目标第二终端在接收到该配置信息时可以回传响应信息或者不回传响应信息给第一终端，而且，该第一配置信息可以通过以下至少一种方式指示第一配置信息关联的第一组播业务：
第一配置信息包含第一组播业务的相关标识；
第一配置信息包含第一组播业务相关联的层2地址；
第一配置信息通过与第一组播业务相关联的层2地址传输；
第一配置信息通过与第一组播业务相关联的单播数据承载和/或信令承载传输；
使目标第二终端在接收到第一配置信息时，通过解析第一配置信息获取上述任意一种或者多种指示信息，确定第一配置信息关联的第一组播业务，建立第一组播业务与第一配置信息的映射关系，避免目标第二终端中需要进行的多个组播业务与多个配置信息之间的混乱，当第二终端确定了第一组播业务与第一配置信息的映射关系之后，通过该第一配置信息配置SDAP层，PDCP(包括安全参数的相关配置)，RLC层，MAC层，PHY层(包括可用资源的配置)的配置，进而进行第一组播业务。
场景2：如图2C所示，在组播连接传输的情况下，第一终端通过与第一组播业务标识相关联的层2地址传输或者通过与用于第一组播业务相关联的组播数据承载和/或信令承载传输的组播连接传输方式给目标第二终端和第二终端A等多个第二终端发送第一配置信息，因此，目标第二终端和第二终端A可以通过该组播传输方式准确获知当前第一配置信息对应的第一组播业务，建立第一组播业务与第一配置信息之间的映射关系，而且，该第一配置信息可以通过以下至少一种方式指示第一配置信息关联的目标第二终端：
第一配置信息包含目标第二终端的相关标识；
第一配置信息包含目标第二终端相关联的层2地址；
使目标第二终端和第二终端A中的目标第二终端在接收到第一配置信息时，通过解析第一配置信息获取上述任意一种或者多种指示信息，确定第一配置信息为自身的关于第一组播业务的配置信息，进而通过该第一配置信息配置SDAP层，PDCP(包括安全参数的相关配置)，RLC层，MAC层，PHY层(包括可用资源的配置)的配置，在配置完成后进行第一组播业务，同时，第二终端A在获取上述任意一种或者多种指示信息时，确定第一配置信息与自身无关，并不进行第一配置信息的配置。

所述第一终端向至少一个第二终端发送针对第一组播业务的第一配置信息，其中，所述第一配置信息用于配置所述至少一个第二终端中的目标第二终端。
可以看出，本发明实施例中，第一终端向至少一个第二终端发送针对第一组播业务的第一配置信息，其中，所述第一配置信息用于配置所述至少一个第二终端中的目标第二终端。可见，第一终端在发送组播业务时，可以单独配置至少一个第二终端中的目标第二终端，而不需要给所有的第二终端集体配置相同的配置，实现了单个终端到单个终端的配置，有利于提升终端配置的灵活性和针对性，提升配置管理效率。
在一个可能的示例中，所述第一组播业务关联设备群组内的多个终端的多个配置信息，所述多个配置信息包括所述第一配置信息，所述多个配置信息中的任意两个配置信息互不相同，所述设备群组为所述第一组播业务的设备群组。
