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(6 th 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。无线通信系统包括终端11、网络侧设备12和接入网设备13。其中，终端11也可以称作终端设备或者用户设备(User Equipment，UE)，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)、可穿戴式设备(Wearable Device)或车载终端(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是核心网设备，其中，核心网设备可以包含但不限于如下至少一项：核心网节点、核心网功能、移动管理实体(Mobility Management Entity，MME)、接入移动管理功能(Access Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户平面功能(User Plane Function，UPF)、策略控制功能(Policy Control Function、PCF)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)、应用功能(Application Function，AF)等。接入网设备13可以是基站。需要说明的是，在本申请实施例中仅以5G系统中的核心网设备为例，但是并不限定此为限。
下面对本申请涉及的内容进行具体说明：
1)目前新提出一个网元，即边缘应用服务发现功能(Edge Application Server Discovery Function，EASDF)，该EASDF可以根据UE的位置，为UE选择路由最优的DNS服务器，然后由5G核心网(5GC)通过扩展协议配置选项(extended Protocol Configuration Options，ePCO)过程，将DNS配置比如DNS服务器的地址信息下发给UE。ePCO过程是指将DNS配置下发给UE的芯片module，然后再转发给UE的操作系统(Operation System，OS)。5GC 为UE下发优化后的DNS服务器地址，主要是为了让应用层的应用享受这种优化。
目前UE在将从非接入层(Non-Access Stratum，NAS)获得的信息比如DNS服务器的地址信息发送给其应用层中的应用时，需要经过UE的内核并且获得内核的支持。但是，UE现有内核不支持传送地址信息给应用，也即不支持传送DNS服务器的地址信息给UE。因此，为了支持DNS服务器地址的传送，需要额外的UE能力。
一种解决方式为，UE具备一种能力，能够将从5GC获得的DNS服务器(server)地址，转发给应用层中的应用，以替换或者更新应用所维护的DNS服务器地址。这种方式的目的是使应用层中的应用使用5GC给UE配置的DNS服务器地址，以享受5GC这种配置带来的好处，比如路由最短、访问时间最短等。另外，UE可以在协议数据单元(Protocol Data Unit，PDU)会话建立或者PDU会话修改请求的过程中，携带这一UE能力的指示(indication)，用来指示UE支持或者不支持将DNS服务器地址发送给应用层中的应用。如果UE支持该能力，则5GC可以在下发DNS服务器地址时，指示UE将该DNS服务器地址转发给对应的应用层中的应用。
2)对于互联网协议第6版(Internet Protocol Version 6，IPV6)多归属(multi-homing)场景，当PDU会话释放时，UE可以将UE内部保存的DNS缓存清空，或者，UE可以将UE内部的与该PDU会话相关的DNS缓存清空。
本申请实施例中，终端内保存DNS配置比如域名服务器的地址信息的位置主要包括：
1、终端的OS。
2、终端中的与应用层中的每个应用对应的保存区域；即，应用层中的每个应用在终端内部都有一个保存区域(也可称为缓存区域)，以保存面向每个应用的DNS配置。这一保存区域位于终端内部。
3、终端的应用层中的每个应用的保存区域，即每个应用都有属于自己的缓存器cache，每个应用自行维护一个DNS配置。这一保存区域位于应用层。
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信息处理方法进行详细地说明。
请参见图2，图2是本申请实施例提供的一种信息处理方法的流程图，该方法由终端执行，如图2所示，该方法包括如下步骤：
步骤21：终端接收地址信息。
本实施例中，上述地址信息可选为服务器地址信息，比如包括域名服务器的地址信息等。该域名服务器可以包括以下至少一项：EASDF、中心DNS(Central DNS，C-DNS)服务器、本地DNS(Local DNS，L-DNS)服务器。
上述地址信息可以为DNS配置信息，比如为DNS服务器的互联网协议(Internet Protocol，IP)地址。比如，上述地址信息可以为EASDF IP地址，也可以为C-DNS IP地址，也可以为L-DNS IP地址。
一种实施方式中，终端可以从网络侧设备接收地址信息，比如从网络侧设备接收域名服务器的地址信息。该网络侧设备比如为5GC网元，包括但不限于接入和移动管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户面功能(User Plane Function，UPF)、EASDF等。
步骤22：终端将地址信息发送至应用。
本实施例中，此步骤中的应用具体为终端的应用层中的应用，包括但不限于应用程序APP、边缘使能客户端(Edge Enabler Client，EEC)、应用程序客户端A(Application Client，AC)等。
比如，终端的OS获取DNS服务器的IP地址之后，可以将该DNS服务器的IP地址转发至应用层中的应用。
本申请实施例的信息处理方法，终端在接收地址信息之后，可以将该地址信息发送至应用，比如发送至终端的应用层中的应用。由此，可以使得该应用享受到网络侧配置的地址信息，从而提升服务性能。
本申请实施例中，为了使得终端准确地转发所获得的地址信息，网络侧设备在下发地址信息时，还可以向终端发送转发指示，该转发指示用于指示终端将接收到的地址信息发送至与地址信息对应的应用，以便终端根据该转发指示来转发地址信息。
可选地，本实施例中的信息处理方法还可以包括：
终端接收转发指示；比如，终端从网络侧设备接收转发指示。
进一步的，上述将地址信息发送至应用可包括：终端根据该转发指示，将地址信息发送至与该地址信息对应的应用。这样，借助转发指示，可以使得终端准确地路由地址信息。
可选地，上述转发指示可以包括与地址信息对应的应用的标识，以便终端根据该标识获知与地址信息对应的应用，从而准确地路由地址信息。
可选地，上述应用的标识(Identification，ID)可以包括但不限于以下至少一项：APP ID、PDU会话ID、EEC ID、AC ID、EEC提供者(provider)ID等。该PDU会话ID可能对应比如为数据网名称(Data Network Name，DNN)、单一网络切片选择辅助信息(Single Network Slice Selection Assistance Information，S-NSSAI)等。也就是说，终端在转发地址信息给对应应用时，可以基于APP ID、PDU会话ID、EEC ID、AC ID和EEC provider ID中的至少一者进行转发。
本申请实施例中，终端在将地址信息发送至应用时，可以通过将地址信息保存到相应的保存区域，并更新或替换原地址信息实现。上述将地址信息发送至应用的过程可以包括以下至少一项：
1)终端将地址信息保存至第一区域，以更新或替换第一区域中保存的原地址信息。该第一区域为应用的应用层保存区域，即第一区域位于终端的应用层，为相应应用在应用层中的保存区域；
2)终端将地址信息保存至第二区域，以更新或替换第二区域中保存的原地址信息。该第二区域为终端中的与应用对应的保存区域，即第二区域位于终端内部，为终端中的与相应应用对应的保存区域。需指出的，此第二区域的位置不是终端的应用层，而为终端内部的保存区域。
