Abstract

本申请提供了一种中继方式的配置方法、中继通信方法、装置及设备，涉及通信技术领域。所述方法包括：核心网设备向终端设备发送第一配置信息，第一配置信息中包括核心网设备为终端设备配置的至少一个中继方式。本申请实施例通过核心网设备为具备Prose能力的终端设备配置中继方式，以使得该终端设备明确中继通信的连接方式，确保终端设备能够实现中继通信。

Description

中继方式的配置方法、中继通信方法、装置及设备 技术领域
本申请实施例涉及通信技术领域，特别涉及一种中继方式的配置方法、中继通信方法、装置及设备。
背景技术
3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)在R13(Release 13，第13版本)ProSe(Proximity Service，近距离通讯服务)架构中引入了中继通信这一概念。
中继通信系统中包括至少两个具备Prose能力的UE(User Equipment，终端设备)，这些UE通常可以分为两类，一类是提供中继服务的UE，另一类是使用中继服务的UE。具备Prose能力的UE可以通过PC5接口与另一个具备Prose能力的UE建立直连通信。在中继通信系统实现为UE通过中继接入网络的情况下，当一个UE既具备通过5G(5th-Generation，第五代移动通信技术)等网络连接外部数据网络的能力，还具备Prose能力时，这个UE可以提供中继服务，也即，这个UE在中继通信系统中充当Relay UE(中继终端设备)；中继通信系统中通过这个UE接入网络的其它UE，使用这个UE提供的中继服务，也即，其它UE在中继通信系统中充当Remote UE(远程终端设备)。在中继通信系统实现为多个UE通过中继实现业务交互的情况下，当一个UE能够为至少两个UE提供通信中转，且能够与这至少两个UE分别通过PC5接口建立直连通信时，这个UE可以提供中继服务，也即，这个UE在中继通信系统中充当Relay UE；中继通信系统中分别通过PC5接口与这个UE建立直连通信的其它UE，使用这个UE提供的中继服务。
然而，针对具备Prose能力的UE在中继通信过程中，如何明确中继通信的连接方式，还需要进一步地讨论和研究。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本申请实施例提供的一种通信系统的系统架构的示意图。如图1所示，该系统架构100可以包括：终端设备10、接入网设备20和核心网设备30。
终端设备10可以指UE、接入终端、用户单元、用户站、移动站、移动台、远方站、远端终端、移动设备、无线通信设备、用户代理或用户装置。可选地，终端设备还可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol，会话启动协议)电话、WLL(Wireless Local Loop，无线本地环路)站、PDA(Personal Digita1Assistant，个人数字处理)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5GS(5th-Generation System，第五代移动通信系统)中的终端设备或者未来演进的PLMN(Pub1ic Land Mobi1e Network，公用陆地移动通信网络)中的终端设备等，本申请实施例对此并不限定。
接入网设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的设备。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，提供无线通信功能的设备的名称可能会有所不同。示例性地，在5GS中，接入网设备可以称为gNodeB或者gNB；在EPS(Evolved Packet System，演进分组系统)中，接入网设备可以称为eNodeB(Evo1ved NodeB，演进型基站)。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，将上述为终端设备提供无线通信功能的装置统称为接入网设备。
核心网设备30是一种部署在核心网中用以为终端设备10提供各项管理和/或认证等功能的功能实体。在一些实现中，核心网设备又可以称为核心网网元。随着通信技术的演进，“核心网设备”这一名称可能会变化。为方便描述，本申请实施例中，将部署在核心网中的功能实体统称为核心网设备。在一个示例中，核心网设备30包括负责用户策略管理的设备。示例性地，在5GS系统中，负责用户策略管理的核心网设备30，可以实现为PCF(Policy Control Function，策略控制功能)。
图2示出了本申请实施例提供的5GS的系统架构的示意图。如图2所示，该系统架构200可以包括：UE、(R)AN((Radio)Access Network，(无线)接入网)、Core(核心网)和DN(Data Network，数据网络)构成。其中，UE、(R)AN、Core是构成系统架构的主要成分，逻辑上它们可以分为用户面和控制面两部分，控制面负责移动网络的管理，用户面负责业务数据的传输。如图2所示，NG2参考点位于(R)AN控制面和Core控制面之间，NG3参考点位于(R)AN用户面和Core用户面之间，NG6参考点位于Core用户面和数据网络之间。其中：
UE：是移动用户与网络交互的入口，能够提供基本的计算能力、存储能力，向用户显示业务窗口，接受用户操作输入。UE可以采用下一代空口技术，与(R)AN建立信号连接、数据连接，从而传输控制信号和业务数据到移动网络。
(R)AN：类似于传统网络里面的基站，部署在靠近UE的位置，为特定区域的授权用户提供入网功能，并能够根据用户的级别，业务的需求等使用不同质量的传输隧道传输用户数据。(R)AN能够管理自身的资源，合理利用，按需为UE提供接入服务，把控制信号和用户数据在UE和核心网之间转发。
Core：负责维护移动网络的签约数据，管理移动网络的网元，为UE提供会话管理、移动性管理、策 略管理、安全认证等功能。在UE附着的时候，为UE提供入网认证；在UE有业务请求时，为UE分配网络资源；在UE移动的时候，为UE更新网络资源；在UE空闲的时候，为UE提供快恢复机制：在UE去附着的时候，为UE释放网络资源；在UE有业务数据时，为UE提供数据路由功能，如转发上行数据到DN：或者从DN接收UE下行数据，转发到(R)AN，从而发送给UE。
DN：是为用户提供业务服务的数据网络，一般客户端位于UE，服务端位于数据网络。数据网络可以是私有网络，如局域网，也可以是不受运营商管控的外部网络，如Internet(互联网)，还可以是运营商共同部署的专有网络，如为了配置IMS(IP Multimedia Core Network Subsystem，IP多媒体网络子系统)服务。
图3是在图2的基础上确定的一种详细系统架构的示意图，其中核心网用户面包括UPF(User Plane Function，用户面功能)；核心网控制面包括AUSF(Authentication Server Function，认证服务器功能)、AMF(Core Access and Mobility Management Function，核心网接入和移动性管理功能)、SMF(Session Management Function，会话管理功能)、UDM(Unified Data Management，统一数据管理)、PCF、AF(Application Function，应用功能)。这些功能实体的功能如下：
UPF：根据SMF的路由规则执行用户数据包转发；
AUSF：执行UE的安全认证；
AMF：UE接入管理和移动性管理；
SMF：UE会话管理；
UDM：用户签约上下文管理；
PCF：用户策略管理；
AF：用户应用管理。
在图3所示的系统架构中，Uu接口为UE与(R)AN之间的参考点，UE通过Uu接口与(R)AN建立接入层连接，交互接入层消息及无线数据传输；N1接口为UE与AMF之间的参考点，UE通过N1接口与AMF建立非接入层(None Access Stratum，NAS)连接，交互NAS消息；N2接口为(R)AN和AMF的参考点，用于NAS消息的发送等；N3接口为(R)AN和UPF之间的参考点，用于传输用户面的数据等；N4接口为SMF和UPF之间的参考点，用于传输例如N3连接的隧道标识信息、数据缓存指示信息，以及下行数据通知消息等信息；N6接口为UPF和DN之间的参考点，用于传输用户面的数据等。
需要说明的是，图2和图3中的各个网元之间的接口名称只是一个示例，具体实现中接口的名称可能为其他的名称，本申请实施例对此不作具体限定。图2和图3中包括的各个网元(例如UPF、PCF等)的名称也仅是一个示例，对网元本身的功能不构成限定。在5G以及未来其它的网络中，上述各个网元也可以是其他的名称，本申请实施例对此不作具体限定。例如，在6G网络中，上述各个网元中的部分或全部可以沿用5G中的术语，也可能采用其他名称，等等，在此进行统一说明，以下不再赘述。此外，应理解，上述各个网元之间的所传输的消息(或信令)的名称也仅仅是一个示例，对消息本身的功能不构成任何限定。
3GPP在R13 ProSe架构中引入了中继通信这一概念。中继通信系统中包括至少两个具备Prose能力的UE(User Equipment，终端设备)，这些UE通常可以分为两类，一类是提供中继服务的UE，另一类是使用中继服务的UE。具备Prose能力的UE可以通过PC5接口与另一个具备Prose能力的UE建立直连通信。
在中继通信系统实现为UE通过中继接入网络的情况下，当一个UE既具备通过5G等网络连接外部数据网络的能力，还具备Prose能力时，这个UE可以提供中继服务，也即，这个UE在中继通信系统中充当Relay UE；中继通信系统中通过这个UE接入网络的其它UE，使用这个UE提供的中继服务，也即，其它UE在中继通信系统中充当Remote UE。请参考图4，其示出了本申请一个实施例提供的中继通信系统的示意图，在该中继通信系统中，远程终端设备(Remote UE)通过中继终端设备(Relay UE)接入网络。如图4所示，远程终端设备可以通过PC5接口与中继终端设备建立直连通信，并通过中继终端设备与5G等网络之间建立的PDU会话实现与外部网络之间的交互。
Remote UE通过Relay UE接入网络的中继通信过程可以采用不同的中继方式，在一个示例中，基于图4所示的中继通信系统，中继通信包括以下几种中继方式：基于层三的中继方式(或称为“基于层三中继(Layer-3 UE-to-Network Relays)”)和基于层二的中继方式(或称为“基于层二中继(Layer 2 UE-to-Network Relays)”)。
请参考图5，其示出了本申请一个实施例提供的基于层三中继的用户面协议栈的示意图。如图5所示，Relay UE与服务于Relay UE的用户面功能实体UPF之间建立PDU会话，Remote UE的数据通过PC5接口发送到Relay UE之后，由Relay UE通过Relay UE与UPF之间建立的PDU会话转发到外部网络。
请参考图6，其示出了本申请一个实施例提供的基于层二中继的用户面协议栈的示意图。如图6所示，Relay UE仅对Remote UE与服务于Remote UE的网络设备(gNB)之间进行空口数据的中转，Remote UE 与服务于Remote UE的用户面功能实体UPF之间建立PDU会话，Remote UE的数据通过Remote UE与UPF之间建立的PDU会话转发到外部网络。
在中继通信系统实现为多个UE通过中继实现业务交互的情况下，当一个UE能够为至少两个UE提供通信中转，且能够与这至少两个UE分别通过PC5接口建立直连通信时，这个UE可以提供中继服务，也即，这个UE在中继通信系统中充当Relay UE；中继通信系统中分别通过PC5接口与这个UE建立直连通信的其它UE，使用这个UE提供的中继服务。请参考图7，其示出了本申请一个实施例提供的中继通信系统的示意图，在该中继通信系统中，中继终端设备(Relay UE)一方面通过PC5接口与具备Prose能力的UE1建立直连通信，另一方面通过PC5接口与具备Prose能力的UE2建立直连通信，从而UE1和UE2能够通过中继终端设备进行业务交互。
多个UE通过中继实现业务交互的中继通信过程也可以采用不同的中继方式，在一个示例中，基于图7所示的中继通信系统，中继通信包括以下几种中继方式：基于层三的中继方式和基于层二的中继方式。
请参考图8，其示出了本申请一个实施例提供的基于层三中继的用户面协议栈的示意图。如图8所示，Relay UE与UE2之间通过PC5接口建立直连通信，UE1的数据通过PC5接口发送到Relay UE之后，由Relay UE通过Relay UE与UE2之间的PC5接口转发到UE2。
请参考图9，其示出了本申请一个实施例提供的基于层二中继的用户面协议栈的示意图。如图9所示，Relay UE仅进行UE1与UE2之间的PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)以下协议层数据进行中转，从非接入层看来，UE1是直接与UE2之间通过PC5接口进行交互。
在一些实现中，具备Prose能力的不同UE在中继通信过程中所能使用的中继方式有所区别。对于中继通信系统实现为UE通过中继接入网络，若Remote UE与Relay UE使用的中继方式不同，则无法正确建立中继通信连接；对于中继通信系统实现为多个UE通过中继实现业务交互，若UE1、UE2和Relay UE使用的中继方式不同，则也无法正确建立中继通信连接。因此，在中继通信过程中，具备Prose能力的UE如何明确中继通信的连接方式(包括自身的中继方式和/或其它UE的中继方式)，还需要进一步地讨论和研究。
基于此，本申请实施例提供了一种中继方式的配置方法以及一种中继通信方法，可用于解决上述技术问题。下面，通过几个实施例对本申请的技术方案进行介绍说明。
应理解，本申请实施例中所述的“中继方式”是指中继通信的连接方式，在一些实现中，“中继方式”又可以称为“中继连接方式”，或者“中继通信方式”等，本申请实施例对此不作限定。为了便于描述，在下述实施例中，将中继通信的连接方式统称为“中继方式”。
请参考图10，其示出了本申请一个实施例提供的中继方式的配置方法的流程图。该方法可以应用于上述图1所示的通信系统中。该方法可以包括如下步骤中的至少部分步骤。
步骤1010，核心网设备向终端设备发送第一配置信息，第一配置信息中包括核心网设备为终端设备配置的至少一个中继方式。
终端设备为具备Prose能力的设备。本申请实施例对终端设备的类型不作限定，在一个示例中，终端设备为提供中继服务的终端设备，可选地，提供中继服务的终端设备可以实现为Relay UE；在另一个示例中，终端设备为使用中继服务的终端设备，可选地，对于UE通过中继接入网络这一中继通信过程，使用中继服务的终端设备可以实现为Remote UE；对于多个UE通过中继实现业务交互这一中继通信过程，使用中继服务的终端设备可以实现为无法直接通过PC5接口建立直连通信的多个UE。
为使得具备Prose能力的终端设备明确中继通信的方式，核心网设备向终端设备发送第一配置信息，该第一配置信息中包括核心网设备为终端设备配置的至少一个中继方式，从而终端设备可以使用核心网设备为其配置的中继方式执行后续的中继通信过程。可选地，核心网设备包括PCF。本申请实施例对第一配置信息的发送方式不作限定，在一个示例中，第一配置信息独立于其它信息，例如，核心网设备向终端设备单独发送第一配置信息；在另一个示例中，第一配置信息承载于核心网设备向终端设备发送的其它信息中，从而可以避免增加核心网设备与终端设备之间往来的消息数量。可选地，在第一配置信息承载于核心网设备向终端设备发送的其它信息中的情况下，第一配置信息承载在Prose配置信息中，或者，第一配置信息承载在URSP(用户设备路径选择策略)配置信息中。
本申请实施例对第一配置信息中包括的至少一个中继方式的类型不作限定，可选地，至少一个中继方式包括以下至少一项：基于层三的中继方式、基于层二的中继方式。当然，核心网设备为终端设备配置的至少一个中继方式还可以包括其它类型的中继方式，例如，至少一个中继方式还可以包括基于N3IWF(Non-3GPP Inter Working Function，非第三代合作伙伴计划互通功能)的中继方式(或称为“基于N3IWF中继”)，应理解，随着通信技术的发展，可能会提出新的中继方式的类型，这些均应属于本申请的保护范围之内。
由上述介绍可知，第一配置信息是用于为终端设备配置中继方式的配置信息，本申请实施例中，第一 配置信息中除了包括至少一个中继方式之外，还可以包括与至少一个中继方式关联的其它信息，例如，各个中继方式分别对应的使用条件信息、与各个中继方式分别对应的指示信息等。下面，针对第一配置信息中可以包括的其它信息进行介绍说明。
在一个示例中，第一配置信息中还包括：与至少一个中继方式分别对应的RSC(Relay Service Code，中继业务代码)，也即，核心网设备为终端设备配置了中继方式与RSC之间的映射关系，从而终端设备基于第一配置信息，即可确定RSC对应的中继方式，或者确定中继方式对应的RSC。由上述介绍可知，实现中继通信过程中的终端设备需要使用相同的中继方式才能确保中继通信的正常进行，因而，终端设备除了明确自身对应的中继方式之外，还需要明确进行中继通信过程中的其它终端设备对应的中继方式，以确保能够使用相同的中继方式进行中继通信。
基于此，可选地，如图11所示，上述方法还包括：步骤1020，其它终端设备向终端设备发送第一RSC；步骤1030，终端设备基于第一配置信息，确定与第一RSC对应的其它终端设备的中继方式。其中，核心网设备为其它终端设备配置的中继方式中，包括与第一RSC对应的中继方式。为了使得终端设备与其它终端设备对于与RSC对应的中继方式的理解一致，核心网设备向不同的终端设备配置的中继方式与RSC之间的映射关系需要保持相同。示例性地，如图11所示，核心网设备为多个终端设备配置相同的中继方式与RSC之间的映射关系，进而不同的终端设备针对某一RSC，可以基于核心网设备配置的映射关系理解出相同的中继方式。
本申请实施例中，针对核心网设备为不同的终端设备配置中继方式的方案，核心网设备为不同的终端设备配置的中继方式可以是相同的，例如，核心网设备为所有的终端设备配置的中继方式均为基于层二的中继方式和基于层三的中继方式；或者，核心网设备基于不同终端设备的能力有区别地为不同的终端设备配置中继方式，例如，终端设备仅支持基于层二的中继方式，则核心网设备为终端设备配置的中继方式为基于层二的中继方式。
针对核心网设备基于不同终端设备的能力有区别地为不同的终端设备配置中继方式的方案，终端设备需要先向核心网设备上报自身的能力。基于此，可选地，如图12所示，上述步骤1010之前，还包括：步骤1000，终端设备向核心网设备发送中继能力信息，中继能力信息包括终端设备支持的中继方式。可选地，终端设备支持的中继方式包括以下至少一项：基于层三的中继方式、基于层二的中继方式。基于此，可选地，核心网设备为终端设备配置的至少一个中继方式属于终端设备支持的中继方式，也即，核心网设备为终端设备配置的中继方式符合终端设备的能力。
在另一个示例中，第一配置信息中还包括：至少一个中继方式分别对应的使用条件信息，某一中继方式对应的使用条件信息用于指示使用该中继方式的条件。本申请实施例对使用条件信息的内容不作限定，示例性地，使用条件信息包括以下至少一项：时间信息、区域信息、业务信息。其中，时间信息用于指示使用中继方式的时间条件；区域信息用于指示使用中继方式的区域条件，可选地，区域信息包括以下至少一项：PLMN对应的标识、TA(Timing Advance，时间提前量)对应的标识、地理区域对应的标识(如经度信息和/或纬度信息)；业务信息用于指示使用中继方式的业务类型，可选地，业务信息包括以下至少一项：业务类型标识、RSC。
综上所述，本申请实施例提供的技术方案，通过核心网设备为具备Prose能力的终端设备配置中继方式，以使得该终端设备明确中继通信的连接方式，确保终端设备能够实现中继通信。并且，核心网设备为具备Prose能力的终端设备配置中继方式时，还可以为终端设备配置与中继方式对应的RSC，从而终端设备基于核心网设备发送的配置信息，既可以确定RSC对应的中继方式，也可以确定中继方式对应的RSC。另外，核心网设备为多个终端设备配置相同的中继方式与RSC之间的映射关系，从而终端设备在后续的中继通信过程中接收到来自于其它终端设备的RSC时，基于核心网设备发送的配置信息，可以明确与该RSC对应的其它终端设备的中继方式，以便于终端设备使用与其它终端设备相同的中继方式，确保中继通信的正常进行。
需要说明的一点是，图10至图12对应的实施例从终端设备与核心网设备之间交互的角度对本申请实施例提供的中继方式的配置方法进行了介绍说明。上述有关终端设备所执行的步骤，可以单独实现为终端设备侧的中继方式的配置方法；上述有关核心网设备所执行的步骤，可以单独实现为核心网设备侧的中继方式的配置方法。
请参考图13，其示出了本申请一个实施例提供的中继通信方法的流程图。该方法可以应用于上述图7所示的中继通信系统中。该方法可以包括如下步骤中的至少部分步骤。
步骤1310，基于第一中继方式，通过中继终端设备实现第一终端设备与第二终端设备进行通信；其中，第一中继方式属于第一终端设备对应的中继方式，且第一中继方式属于中继终端设备对应的中继方式，且第一中继方式属于第二终端设备对应的中继方式。
本实施方式中的中继通信系统包括第一终端设备、中继终端设备、第二终端设备。其中，中继终端设 备既可以通过PC5接口与第一终端设备建立直连通信，也可以通过PC5接口与第二终端设备建立直连通信；而第一终端设备和第二终端设备无法直接通过PC5接口建立直连通信，从而第一终端设备与第二终端设备之间的业务交互通过中继终端设备中转。
由上述介绍可知，为了确保中继通信的正常进行，在通过中继终端设备实现第一终端设备与第二终端设备进行通信的过程中，第一终端设备、中继终端设备、第二终端设备所使用的中继方式需要保持一致。基于此，本申请实施例基于第一中继方式通过中继终端设备实现第一终端设备与第二终端设备进行通信。其中，第一中继方式是第一终端设备、中继终端设备、第二终端设备共同对应的中继方式，也即，第一中继方式属于第一终端设备对应的中继方式，且第一中继方式属于中继终端设备对应的中继方式，且第一中继方式属于第二终端设备对应的中继方式。有关第一中继方式的确定过程等的介绍说明，请参见下述实施例，此处不多赘述。

本申请实施例对中继通信系统中各个终端设备分别对应的中继方式的确定方式也不作限定，在一个示例中，第一终端设备对应的中继方式包括以下任意一项：第一终端设备支持的中继方式、第一终端设备支持且由核心网设备为第一终端设备配置的中继方式；中继终端设备对应的中继方式包括以下任意一项：中继终端设备支持的中继方式、中继终端设备支持且由核心网设备为中继终端设备配置的中继方式；第二终端设备对应的中继方式包括以下任意一项：第二终端设备支持的中继方式、第二终端设备支持且由核心网设备为第二终端设备配置的中继方式。
综上所述，本申请实施例提供的技术方案，针对多个终端设备通过中继实现业务交互的中继通信系统，通过各个终端设备使用一致的中继方式执行中继通信过程，避免由于终端设备所使用的中继方式不匹配导致无法建立中继连接，确保中继通信的正常进行。
本申请实施例对确定第一中继方式的主体不作限定，在一个示例中，第一中继方式由第一终端设备确定，例如，第一终端设备可以获取中继终端设备和第二终端设备对应的中继方式，并结合自身对应的中继方式来确定第一中继方式；在另一个示例中，第一中继方式由第二终端设备确定，例如，第二终端设备可以获取中继终端设备和第一终端设备对应的中继方式，并结合自身对应的中继方式来确定第一中继方式；在再一个示例中，第一中继方式由中继终端设备确定，例如，中继终端设备可以获取第一终端设备和第二终端设备对应的中继方式，并结合自身对应的中继方式来确定第一中继方式；在又一个示例中，第一中继方式直接由核心网设备配置，例如，核心网设备为第一终端设备、第二终端设备和中继终端设备配置相同且唯一的中继方式，后续各个终端设备使用核心网设备配置的中继方式进行中继通信。
下面，针对第一中继方式由第一终端设备确定、第一中继方式由第二终端设备确定这两个方案分别进行介绍说明。应理解，本领域技术人员在了解了本申请的技术方案后，将容易想到由中继终端设备确定第一中继方式的技术方案，这些也应当属于本申请的保护范围之内。实际应用中，考虑到各个终端设备之间的消息往来数量以及处理开销等因素，可以采用第一终端设备或第二终端设备确定第一中继方式的技术方案。
首先，介绍说明由第一终端设备确定第一中继方式的技术方案。
在一种可能的实施方式中，如图14所示，上述步骤1310之前，还包括如下几个步骤。
步骤1302，第二终端设备向中继终端设备发送第二信息，第二信息用于指示第二终端设备对应的中继方式。
本实施方式是由第一终端设备确定第一中继方式，因而第二终端设备需要将自身对应的中继方式发送至第一终端设备，而由于第二终端设备与第一终端设备无法通过PC5接口建立直连通信，因而，第二终端设备需要通过中继终端设备中转，以达到与第一终端设备进行信息交互的目的。
基于此，第二终端设备向中继终端设备发送第二信息，该第二信息用于指示第二终端设备对应的中继方式。有关第二信息的具体发送方式，请参见下述实施例，此处不多赘述。本申请实施例对第二终端设备 对应的中继方式的指示方式不作限定，在一个示例中，第二信息中明确指示第二终端设备对应的中继方式，例如，第二信息中包括第二终端设备对应的中继方式的参数配置等；在另一个示例中，第二信息中隐含指示第二终端设备对应的中继方式，例如，第二信息中包括与第二终端设备对应的中继方式对应的RSC。针对第二信息中包括与第二终端设备对应的中继方式对应的RSC的情况，核心网设备可以事先为各个终端设备配置相同的中继方式与RSC之间的映射关系，具体的配置过程可以参见图10至图12对应的实施例，此处不多赘述。
步骤1304，中继终端设备向第一终端设备发送第一信息，第一信息用于指示第二中继方式，且第一信息是基于第二信息确定的。
由于第一中继方式是各个终端设备均使用的中继方式，因而中继终端设备也需要将自身对应的中继方式发送至第一终端设备。本实施方式中，中继终端设备在接收到来自于第二终端设备的第二信息之后，基于第二信息以及中继终端设备自身对应的中继方式确定第一信息，并向第一终端设备发送第一信息，以将中继终端设备和第二终端设备对应的中继方式告知第一终端设备。

下面，针对信息的发送方式进行介绍说明。

第二终端设备可以将第二信息承载在第二广播信息中广播出去，从而中继终端设备在检测到第二终端设备的第二广播信息时接收到第二信息。或者，第二终端设备可以在注册至中继终端设备时，向中继终端设备发送第二信息。或者，第二终端设备可以在与中继终端设备建立连接的过程中，向中继终端设备发送第二信息。
步骤1304A，中继终端设备广播第一广播信息，第一信息承载在第一广播信息中。
中继终端设备接收到来自于第二终端设备的第二信息后，基于第二信息以及中继终端设备自身对应的中继方式，确定第一信息，并将第一信息承载在第一广播信息中广播出去，从而第一终端设备在检测到中继终端设备的第一广播信息时接收到第一信息。
步骤1306，第一终端设备基于第二中继方式和第一终端设备对应的中继方式，确定第一中继方式。
在另一个示例中，如图16所示，上述步骤1302和步骤1304分别实现为如下步骤(步骤1302实现为步骤1302B和步骤1302C，步骤1304实现为步骤1304B和步骤1304C，步骤1306实现为步骤1306)。

步骤1302C，第二终端设备向中继终端设备发送第二发现响应，第二信息承载在第二发现响应中。
第二终端设备检测到中继终端设备的第二发现请求后，若第二终端设备确定通过中继终端设备与第一终端设备进行通信，如第二终端设备也需求进行发现请求指示的中继业务，则第二终端设备可以向中继终端设备发送第二发现响应，以响应中继终端设备的第二发现请求。在第二终端设备向中继终端设备返回第二发现响应时，可以在第二发现响应中承载第二信息。
步骤1304C，中继终端设备向第一终端设备发送第一发现响应，第一信息承载在第一发现响应中。
中继终端设备接收到第二发现响应即可解析出第二信息，然后基于第二信息和中继终端设备自身对应的中继方式，确定第一信息，并将第一信息承载在第一发现响应中返回至第一终端设备，以响应于第一终端设备的第一发现请求。
步骤1306，第一终端设备基于第二中继方式和第一终端设备对应的中继方式，确定第一中继方式。

在一种可能的实施方式中，如图17所示，上述步骤1310之前，还包括如下几个步骤。
步骤1322，第一终端设备向中继终端设备发送第四信息，第四信息用于指示第一终端设备对应的中继方式。
本实施方式是由第二终端设备确定第一中继方式，因而第一终端设备需要将自身对应的中继方式发送至第二终端设备，而由于第一终端设备与第二终端设备无法通过PC5接口建立直连通信，因而，第一终端设备需要通过中继终端设备中转，以达到与第二终端设备进行信息交互的目的。
基于此，第一终端设备向中继终端设备发送第四信息，该第四信息用于指示第一终端设备对应的中继方式。有关第四信息的具体发送方式，请参见下述实施例，此处不多赘述。本申请实施例对第一终端设备对应的中继方式的指示方式不作限定，在一个示例中，第四信息中明确指示第一终端设备对应的中继方式，例如，第四信息中包括第一终端设备对应的中继方式的参数配置等；在另一个示例中，第四信息中隐含指示第一终端设备对应的中继方式，例如，第四信息中包括与第一终端设备对应的中继方式对应的RSC。针对第四信息中包括与第一终端设备对应的中继方式对应的RSC的情况，核心网设备可以事先为各个终端设备配置相同的中继方式与RSC之间的映射关系，具体的配置过程可以参见图10至图12对应的实施例，此处不多赘述。
步骤1324，中继终端设备向第二终端设备发送第五信息，第五信息用于指示第三中继方式，且第五信息是基于第四信息确定的。

实际应用中，第一终端设备可能并未执行设备发现流程，而是直接发起连接建立。在第一终端设备直接发起连接建立时，第一终端设备可以广播第一连接建立请求。由于第一中继方式由第二终端设备确定， 因而第一终端设备需要向第二终端设备指示第一终端设备对应的中继方式，从而，第一终端设备可以在广播的第一连接建立请求中携带第四信息，该第四信息用于指示第一终端设备对应的中继方式。
