具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括第一终端11和网络侧设备12。其中，第一终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented  reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人第一终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等第一终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定第一终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备12也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备12可以包括基站、WLAN接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
设备到设备(Device to Device，D2D)通信，指数据传输不通过基站，而是允许一个移动终端设备与另一个移动终端设备直接通信。D2D源于4G时代，被称为LTE近距离服务(LTE Proximity Services，ProSe)技术，是一种基于3GPP通信系统的近距离通信技术，主要包括两大功能：直连发现(Direct discovery)功能，终端发现周围有可以直连的终端；直连通信(Direct communication)功能，与周围的终端进行数据交互。
在4G时代D2D通信主要仅应用于公共安全领域，进入5G时代，由于车联网、自动驾驶、可穿戴设备等物联网应用将大量兴起，进而衍生了5G ProSe技术。
对于5G ProSe direct communication，它允许终端与周围的终端进行数据交互。这种数据交互既可以通过传统的UE1-5G核心网(5GC)-应用服务器(Application Server)-UE2路径，又可以包括基于PC5链路的direct communication机制。
在5G ProSe direct communication场景中，如果直连通信由终端的某个应用触发，网络侧设备会为终端配置路径偏好(path preference)与ProSe应用或应用标识(ProSe identifier)的映射规则(以下简称第一映射规则)。
第一映射规则是一个映射列表，包含若干条映射规则，每条映射规则可以包含如下之一：某个应用标识与路径偏好的映射关系(简称为第一类映射关系)，所有应用与路径偏好的映射关系(简称为第二类映射关系)。
终端会根据网络侧设备配置的第一映射规则进行路径偏好选择。
如果所述应用也有路径偏好，如何向终端指示应用的路径偏好，目前相关技术中 只可以通过网络侧设备的策略更新来实现，即网络侧设备根据应用层的需求更新第一映射规则，将第二类映射关系包含在第一映射规则中下发给终端，会对终端造成一定的信令开销。另外，如果终端同时被配置了第一类映射关系和第二类映射关系，终端可能需要匹配完所有的路径偏好映射规则，才能确定应用的路径偏好，这对终端来说是不友好的，因为在路径偏好映射规则的数量很多的情况下，终端必须进行一些不必要的匹配来最终确定一个路径偏好，导致终端的计算资源被浪费，且终端的计算复杂度较高，用户的等待时间较长。
为了解决上述问题，本申请实施例提供了路径偏好确定方法。下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的路径偏好确定方法进行详细地说明。
图2为本申请实施例提供的路径偏好确定方法的流程示意图之一，如图2所示，该路径偏好确定方法包括以下步骤：
步骤200、第一终端获取第一信息；
需要说明的是，第一信息用于指示路径偏好。
路径偏好表示的是终端之间通信所偏好的路径。
可选地，所述路径偏好包括以下至少一项：偏好PC5，偏好Uu，无偏好。
若路径偏好为偏好PC5，则数据的流向使用PC5机制，即通过建立第一终端与第二终端之间的PC5连接(link)，通过PC5 link进行数据传输。
若路径偏好为偏好Uu，则数据的流向使用Uu机制，即第一终端建立第一PDU会话，通过数据面发给应用服务器；应用服务器通过第二终端建立的第二PDU会话发送下行数据给第二终端，从而实现第一终端与第二终端之间的通信。
若路径偏好为无偏好，则数据的流向根据终端实现确定，可以使用PC5机制或Uu机制实现第一终端与第二终端之间的通信。
可选地，获取可以理解为从配置获得、接收、通过请求后接收、通过自学习获取、根据未收到的信息推导获取或者是根据接收的信息处理后获得，具体可根据实际需要确定，本申请实施例对此不作限定。
步骤201、所述第一终端根据所述第一信息，确定目标应用的路径偏好。
第一终端获取第一信息之后，进而，第一终端可以根据第一信息，确定目标应用的路径偏好。
在本申请实施例中，终端通过获取第一信息，并根据第一信息确定目标应用的路径偏好，相比于通过网络侧设备的策略更新向终端指示应用的路径偏好，可节省终端信令开销和计算资源，降低了终端的计算复杂度，可缩短用户的等待时间。
在一些实施例中，所述第一信息包括以下至少一项：
a)第一指示信息，所述第一指示信息用于指示所述目标应用的路径偏好；
一种实施方式中，所述第一终端获取第一信息，包括：
所述第一终端的近距离业务ProSe层获取所述第一终端的应用层(Application layer)或上层(Upper layer)发送的所述第一指示信息。
图3为本申请实施例提供的路径偏好确定方法的交互示意图。
可以理解的是，可以通过第一终端的ProSe层与应用层的层间交互，向第一终端指示目标应用的路径偏好。
进一步地，第一终端的ProSe层获取到第一指示信息之后，根据第一指示信息，确定目标应用的路径偏好。
如果所述第一指示信息指示所述目标应用的路径偏好为偏好PC5，则所述第一终端使用PC5上的5G ProSe direct communication机制与第二终端进行通信。如果所述第一指示信息指示所述所述目标应用的路径偏好为偏好Uu，则第一终端使用Uu机制与第二终端进行通信。如果所述第一指示信息指示所述目标应用的路径偏好为无偏好，则使用哪种机制取决于UE实现。示例性的，UE可以根据上一次该目标应用的路径选择一个路径。
b)路径偏好映射规则列表，所述路径偏好映射规则列表包括路径偏好映射规则以及所述路径偏好映射规则对应的优先级信息；
其中，每条所述路径偏好映射规则用于指示一个路径偏好。
在一些实施例中，所述每条所述路径偏好映射规则包括一个路径偏好与一个应用的映射关系，或者，一个路径偏好与一个应用标识的映射关系，或者，一个路径偏好与所有应用的映射关系。
可选地，所述路径偏好映射规则列表包括第一类映射关系和第二类映射关系；
其中，所述第一类映射关系为特定应用与路径偏好的映射关系；所述第二类映射关系为所有应用与路径偏好的映射关系。
即，一个路径偏好与一个应用的映射关系，或者，一个路径偏好与一个应用标识的映射关系，可以称为第一类映射关系。一个路径偏好与所有应用的映射关系，可以称为第二类映射关系。
需要说明的是，第一类映射的优先级应该比第二类映射关系高。这很容易理解，因为第二类映射关系相当于规定了所有应用的一个默认映射关系，即例如，默认所有应用都偏好PC5。而当某个应用被额外配置了一个路径偏好(第一类映射关系)，那么这个额外配置的优先级(第一类映射关系)应该是要比其默认配置的高(第二类映射关系)。
在本申请实施例中，路径偏好映射规则列表除了包括路径偏好映射规则，还包括所述路径偏好映射规则对应的优先级信息。可以理解，终端根据路径偏好映射规则的优先级信息，可以更快速地匹配到目标应用的路径偏好，节省终端计算资源，降低计算复杂度。
可选地，所述每条所述路径偏好映射规则还包括第二指示域，所述第二指示域用 于指示所述路径偏好映射规则是否包含应用标识；

一种实施方式中，所述路径偏好映射规则列表包括：按照所述优先级信息排序的至少一条路径偏好映射规则。
即网络侧设备下发给第一终端的路径偏好映射规则列表已经是排序过的，也就是说网络侧设备在编码路径偏好映射规则列表时已按照一定的优先级顺序为各路径偏好映射规则进行了排序。终端成功匹配到某一条规则后即可停止其他路径偏好映射规则的匹配。从而节省终端计算资源，降低计算复杂度，降低用户的等待时间。
一种实施方式中，每条所述路径偏好映射规则具有第一指示域，所述第一指示域用于指示所述优先级信息。

若路径偏好为偏好PC5，则数据的流向使用PC5机制，即通过建立第一终端与第二终端之间的PC5连接(link)，通过PC5 link进行数据传输。

若路径偏好为无偏好，则数据的流向根据终端实现确定，可以使用PC5机制或Uu机制实现第一终端与第二终端之间的通信。
