请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个UE11以及若干个接入设备12。
其中，UE11可以是指向用户提供语音和/或数据连通性的设备。UE11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE11也可以是无人飞行器的设备。或者，UE11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，UE11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
接入设备12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，接入设备12可以是4G系统中采用的演进型接入设备(eNB)。或者，接入设备12也可以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入设备12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对接入设备12的具体实现方式不加以限定。
接入设备12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G 的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，UE11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个接入设备12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
如图2所示，本公开实施例提供一种信息处理方法，其中，被第一用户设备UE执行，所述方法包括：
S110：获取缺省PC5安全策略，其中，所述缺省PC5安全策略，用于在未获取到目标基于邻近通信服务ProSe业务的特定PC5安全策略时，用于保护所述目标ProSe业务的PC5连接。
本公开实施例中提供的信息处理方法，可应用于UE，该UE可以为第一UE，则与第一UE进行通信的PC5通信的UE为第二UE。该第一UE可为需要与第二UE进行PC5连接并基于PC5连接进行PC5通信的UE。第二UE可为任意不同于第一UE的UE。该第一UE可以为PC5通信的发起端或者接受端。
此处的缺省PC5安全策略为PC5安全策略的一种，是用于在没有获取到专门针对目标ProSe业务的特定PC5安全策略时，就可以使用缺省PC5安全策略提供PC5连接的安全保障。
示例性地，缺省PC5安全策略可为通信运营商配置的安全策略，可以面向通信网络的所有ProSe业务。例如，缺省PC5安全策略可以指示以下至少之一：
需要，指示基于PC5连接的PC5通信信令和/或数据需加密和/或完整性保护，即在基于PC5连接的PC5通信时，需要进行通信信令和/或数据的完整性保护和/或加密；
可选地，指示基于PC5的PC5通信信令和/或数据可以加密也可以不加密和/或可进行完整性保护也可不进行完整性保护；
不需要，指示基于PC5连接的PC5通信信令和/或数据无需加密和/或完整性保护，即在基于PC5连接的PC5通信时，无需进行通信信令和/或数据的完整性保护和/或加密。
在一些实施例中，所述缺省PC5安全策略针对不同类型的ProSe业务可配置不同的安全保护要求；和/或根据不同的PC5通信环境，和/或不同的PC5通信UE，配置有不同的PC5安全保护要求。
如此，可以即便是基于缺省PC5安全策略，也可以根据不同ProSe业务、通信环境和/或通信UE，选择合适当前通信状况的PC5安全保护要求进行安全的PC5通信。
当然以上仅仅是对缺省PC5安全策略的举例说明，具体实施例不局限于该举例。
在本公开实施例中，所述缺省PC5安全策略可为公用PC5安全策略，即为多种ProSe业务所供养的PC5策略。而特定PC5安全策略仅仅针对其指定的ProSe业务。
通过缺省PC5安全策略的引入，可以使得UE在未获取到针对目标ProSe业务的特定PC5安全策略时，依然可以基于缺省PC5安全策略保护PC5连接建立并进行基于PC5连接的PC5通信，减少因为未获取到针对目标ProSe业务的特定PC5安全策略导致的PC5连接无法建立及PC5通信无法实现的问题。
在一些实施例中，如图3所示，本公开实施例提供一种信息处理方法可包括：
S120：当获取到目标ProSe业务的特定PC5安全策略时，根据特定PC5安全策略保护基于目标ProSe业务的PC5连接。
在本公开实施例中，若获取到目标ProSe业务的特定PC5安全策略，则以特定PC5安全策略为准，进行针对目标ProSe建立的PC5连接的保护。
即如果同时获取到了缺省PC5安全策略和特定PC5安全策略，则优先使用特定PC5安全策略。
该特定PC5安全策略可以是目标ProSe业务的服务提供商或者通信运营商针对目标ProSe专门制定的，因此目标ProSe业务的特定PC5安全策略是针对目标ProSe业务的安全需求专门制定的，从而具有业务的特殊性，优先根据目标ProSe业务的特定PC5安全策略提供PC5连接安全保护，可以满足目标ProSe业务的特定安全需求。
在一些实施例中，如图4所示，所述方法包括：
S100：从策略控制功能PCF接收所述目标ProSe业务的特定PC5安全策略；或者，从ProSe应用服务器接收所述目标ProSe业务的特定PC5安全策略。
UE在进行目标ProSe业务的PC5通信(或者说直连通信，或者sidelink(SL)通信)之前，可以先向PCF或者目标ProSe的ProSe应用服务器请求所述特定PC5安全策略。
示例性地，UE在向PCF请求所述特定PC5安全策略之前，可以查询本地是否存储有该目标ProSe业务的特定PC5安全策略，如果UE本地存储有，且确定为最新特定PC5安全策略的版本，则无需向PCF或者ProSe应用服务器再次请求。
示例性地，所述UE从PCF和/或ProSe应用服务器接收目标ProSe业务的特定PC5安全策略可包括：
向PCF或者ProSe应用服务器发送请求消息，其中，所述请求消息包含：目标ProSe业务的业务标识；
接收PCF或者ProSe应用服务器返回的响应消息。
在一个实施例中，所述响应消息包括以下至少之一：
所述特定PC5安全策略的策略标识；
所述特定PC5安全策略的策略条目；
否认反馈，指示无所述目标ProSe业务的特定PC5安全策略。
当UE没有从PCF或者ProSe应用服务器请求到目标ProSe业务的特定PC5安全策略时，或者响应消息指示携带特定PC5安全策略的字段为空时，都可认为没有获取到对应的特定PC5安全策略，则此时根据缺省PC5安全策略进行目标ProSe业务的PC5连接的安全保护。
当然以上仅仅是从PCF或者ProSe应用服务器获取特定PC5安全策略的一种方式，具体实现过程中UE在请求PC5通信时，网络侧的PCF或者ProSe应用服务器可以在请求ProSe通信的响应消息中将特定PC5安全策略的相关信息发送给UE，若UE在请求ProSe通信的响应消息中未发现特定PC5安全策略的相关信息，则可认为没有获取到目标ProSe业务的特定PC5安全策略。
在一些实施例中，不同ProSe业务的所述特定PC5安全策略不同。
例如，不同ProSe业务的特定PC5安全策略的策略内容不同和/或策略标识不同，以满足不同ProSe业务的安全需求。
在一些实施例中，所述目标ProSe业务的特定PC5安全策略是根据所述目标ProSe业务的安全需求确定的。
在一些实施例中，所述缺省PC5安全策略可预先配置在所述第一UE内；
或者，
所述缺省PC5安全策略是从PCF接收的。
例如，缺省PC5安全策略可以是规定在通信标准中，并且基于通信标准预先写入到UE中的。如此，任何一个UE都预先知晓缺省PC5安全策略，从而在没有获取到目标ProSe业务的特定PC5安全策略时，就可以基于缺省PC5安全策略进行目标ProSe业务的通信。
在一些实施例中，所述方法还包括：
根据所述缺省PC5安全策略或者特定PC5安全策略，与第二UE协商保护所述目标ProSe业务的PC5连接的安全参数。
该安全参数包括但不限于以下至少之一：
指示PC5信令是否加密的第一参数；
指示PC5数据是否加密的第二参数；
指示PC5信令是否需完整性保护的第三参数；
指示PC5数据是否需完整性保护的第四参数；
指示加密和完整性保护算法(相同算法)的第五参数；
当然以上仅仅是举例，具体实现时不局限于上述举例。
在本公开实施例中，第一UE在与第二UE进行PC5通信建立之前，先协商安全参数。具体根据缺省PC5安全策略或者特定PC5安全策略来进行安全参数的协商。
示例性地，在获取到目标ProSe业务的特定PC5安全策略时，会根据特定PC5安全策略，与第二UE协商保护目标ProSe业务的PC5连接的安全参数，在未获取到目标ProSe业务的特定PC5安全策略时，会根据缺省PC5安全策略，与第二UE协商保护目标ProSe业务的PC5连接的安全参数。
在一些实施例中所述缺省PC5安全策略，包括：
针对任意ProSe业务的缺省安全保护要求。
由于缺省PC5安全策略是针对任意ProSe业务的缺省安全保护要求，因此可以在没有获取到特定PC5安全保护策略时，针对任意ProSe业务都可以按照缺省PC5安全策略进行PC5连接的保护。
在一些实施例中，所述特定PC5安全策略的优先级高于所述缺省PC5安全策略。
缺省PC5安全策略相当于各ProSe业务的特定PC5安全策略的备用安全策略，在特定PC5安全策略未配置或者异常引起的未获取到时，可以基于缺省PC5安全策略进行目标ProSe业务的PC5连接的安全保护。
如图5所示，本公开实施例提供一种信息处理方法，其中，被PCF执行，所述方法包括：
S210：配置缺省PC5安全策略，其中，所述缺省PC5安全策略，用于在未获取到目标基于邻近的服务ProSe业务的特定PC5安全策略，用于保护所述目标ProSe业务的PC5连接。
PCF可以存储缺省PC5安全策略，该缺省PC5安全策略可以是网管设备配置到PCF的。
在一些实施例中，该S210可包括以下至少之一：
初始配置缺省PC5安全策略；
定期或不定期更新缺省PC5安全策略。
不定期更新缺省PC5安全策略，可包括：引入新的ProSe业务或者新类型的ProSe业务时的缺省PC5安全策略更新。
当然以上仅仅是举例，具体实现时不局限于上述任意举例。
在一些实施例中，所述方法还包括：
将所述缺省PC5安全策略发送给UE。
若PCF配置有缺省PC5安全策略之后，会主动推送或者基于UE请求的向UE发送所述PC5安全策略，以使得UE存储有缺省PC5安全策略。
在一些实施例中，所述方法还包括：
配置针对所述目标ProSe业务的所述特定PC5安全策略。
PCF还可以根据ProSe应用服务器的指示，配置针对目标ProSe业务的特定PC5安全策略。
若PCF配置有特定PC5安全策略之后，还可以将该特定PC5安全策略发送给UE，供UE在进行目标ProSe业务通信时，保护目标ProSe业务的PC5连接。
在一些实施例中，所述特定PC5安全策略的优先级高于所述缺省PC5安全策略。
在一些实施例中，所述缺省PC5安全策略，包括：
针对任意ProSe业务的缺省安全保护要求。
缺省PC5安全策略包含针对任意ProSe业务的缺省安全保护要求，如此在任意一个ProSe业务的特定PC5安全策略未获取到时，都可以基于缺省PC5安全策略提供对应ProSe业务的PC5连接的保护。
PC5直连通信(简称PC5通信)可通过PCF或ProSe应用服务器向ProSeUE提供的PC5安全策略来确保的，这些PC5安全策略包含在需要安全保护的ProSe业务列表中。其中，每个ProSe业 务都可分配了其对应的PC5安全策略。
ProSe业务的PC5安全策略配置可以使用eV2X业务的PC5安全策略配置机制。PC5安全策略的协商和实施还可以使用相关技术中定义的过程，其中PC5安全策略可在相关流程消息中携带。
然而在实际部署中，一些ProSe业务提供者可能没有为其提供的特定ProSe业务分配相应的安全策略，这将导致UE的PC5安全策略缺失。如果某台ProSe终端在为特定5GProSe业务建立直连通信时，没有配置PC5安全策略，则无法与对端终端进行PC5安全策略的协商和实施，从而无法建立终端间的直连通信。
5GProSe业务可能非常多样化，并由各ProSe业务提供商提供，其中一些提供商可能无法有效地为其提供的特定服务分配PC5安全策略。
在本申请实施例中，
定义不同类型的PC5安全策略；
配置缺省PC5安全策略(又可以称为默认PC5安全策略)，通过PC5接口保护ProSe业务。
将已配置的缺省PC5安全策略安全地下发到UE。
当UE上配置了多种PC5安全策略，例如，配置了缺省PC5安全策略和特定PC5安全策略时，需选择使用哪种PC5安全策略。
特定PC5安全策略与特定的ProSe业务绑定。
缺省PC5安全策略与任何特定的ProSe业务无特殊绑定关系，当ProSe业务提供者没有为特定的ProSe业务提供PC5安全策略时使用此安全策略。
特定PC5安全策略的配置是基于特定ProSe业务的实际安全需求，根据特定PC5安全策略，可以分别有需要“REQUIRED”、可选“PREFERRED”、不需要“NOT NEEDED”选项用于加密和完整性保护。
缺省PC5安全策略的配置不是基于具体的ProSe业务的实际安全需求，可以由支持ProSe业务的运营商决定。缺省PC5安全策略还可以分别为加密和完整性保护提供“REQUIRED”、“PREFERRED”、“NOT NEEDED”选项。
PCF或ProSe应用服务器可以为终端提供具体的PC5安全策略。策略下发受非接入层(NAS)安全保护。如果ProSe业务提供商没有提供这种类型的PC5安全策略，那么可能不会为UE提供这种特定PC5安全策略。
缺省PC5安全策略可以在UE上预先配置，也可以由PCF向终端下发。下发受NAS安全保护。这种类型的PC5安全策略可由运营商配置，并由PCF提供给UE。
由于引入了不同类型的PC5安全策略，ProSe UE在与其他UE建立PC5连接之前，可能会同时配置有不同类型的PC5安全策略。UE需要根据不同PC5安全策略类型的优先级确定与对端UE直连通信时使用的安全策略。
特定PC5安全策略优先级高于缺省PC5安全策略的优先级。
如果UE上只配置了缺省PC5安全策略，则UE建立PC5连接时使用缺省PC5安全策略。
如果UE上同时配置了PC5安全策略和缺省PC5安全策略，则使用特定PC5安全策略。
如图6所示，本公开实施例提供一种信息处理装置，其中，所述装置包括：

在一些实施例中，所述目标ProSe业务的特定PC5安全策略是根据所述目标ProSe业务的安全需求确定的。

或者，
所述缺省PC5安全策略是从PCF接收的。

针对任意ProSe业务的缺省安全保护要求。
在一些实施例中，所述特定PC5安全策略的优先级高于所述缺省PC5安全策略。
