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和网络侧设备12。其中，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。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 and Mobility 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)、统一数据管理(Unified Data Management，UDM)，统一数据仓储(Unified Data Repository，UDR)、归属用户服务器(Home Subscriber Server，HSS)、集中式网络配置(Centralized network configuration，CNC)、网络存储功能(Network Repository Function，NRF)，网络开放功能(Network Exposure Function，NEF)、本地NEF(Local NEF，或L-NEF)、绑定支持功能(Binding Support Function，BSF)、应用功能(Application Function， AF)等。需要说明的是，在本申请实施例中仅以NR系统中的核心网设备为例进行介绍，并不限定核心网设备的具体类型。
首先，对本申请实施例中涉及的相关概念进行介绍：
服务中断最小化(Minimization of service Interruption，MINT)是指当网络由于某些事件(例如火灾或一些自然灾害)而无法为终端提供通信服务时，需要尽量减少服务中断的时间。网络发生灾难包括无线接入网(Radio Access Network，RAN)灾难和核心网(Core Network，CN)灾难。
MOCN(Multi-Operator Core Network)，是指多个运营商共用一套无线网络，即同一套基站可以同时连接到多个运营商(Operator，Op)的核心网。如图2所示：
各运营商共享无线网络资源(小区载频)，不共享CN节点，CN节点属于不同运营商。
RAN节点通过系统广播消息广播支持的PLMN的信息，例如PLMN ID。UE向RAN发起RRC连接建立时，会向RAN提供接入哪个运营商的信息，例如携带目标运营商的PLMN ID；RAN根据该信息将UE的请求路由到对应的运营商的核心网。
例如，在MOCN共享场景下，Op1发生CN灾难，且终端没有其他可用PLMN的前提下，如何在不执行网络选择过程(或者用户不感知网络变化)的条件下，使得Op1的用户可以通过Op2获取连接服务。
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获取方法进行详细地说明。

其中，第一信息用于指示第一网络处于灾难条件时为终端提供灾难漫游服务的第二网络；灾难条件包括核心网设备发生灾难和/或接入网设备发生灾难。
具体地，第一信息可以是核心网设备向接入网设备发送的。
为了支持在网络发生灾难时，由接入网设备来选择提供灾难漫游的网络，网络侧为接入网设备配置第一信息，第一信息例如包括至少一个第二网络的信息，如第二网络的网络标识、优先级信息等。
本实施例的方法，接入网设备获取第一信息；第一信息用于指示第一网络处于灾难条件时为终端提供灾难漫游服务的第二网络；该灾难条件包括核心网设备发生灾难和/或接入网设备发生灾难，使得在第一网络处于灾难条件时，终端能够获知可接入的合适的网络，实现灾难漫游。
可选地，第一信息包括以下至少一项：
第一指示信息，第一指示信息用于指示第二网络对应的灾难条件的类型；
第二网络的网络标识；
第二网络的优先级信息。
例如，灾难条件的类型包括核心网设备发生灾难、接入网设备发生灾难。
具体地，如图4所示，第一信息可以通过列表的形式表示，例如第一信息中包括第二网络的网络标识ID，第二网络的优先级信息可以隐式指示或显式指示。
可选地，隐式指示例如可以采用如下方式：
第二网络的网络标识的数量为至少两个，至少两个第二网络的网络标识在第一信息中按照优先级递增或优先级递减的顺序排列。
图5为网络标识的格式，网络标识中包括：移动国家码(Mobile Country Code，MCC)、移动网络码(Mobile Network Code，MNC)。
如图6所示，显式指示例如可以在网络标识中的已有字段或新增字段中设置优先级信息。例如图6中的PP字段，该PP字段用于指示网络优先级，例如可以采用3个比特表示，000表示优先级1，010表示优先级3，100表示优先级5，例如优先级1表示最高优先级。
可选地，第一网络的核心网设备发生灾难以及接入网设备发生灾难的情况下，第二网络可以是独立配置的，也可以是一起配置的，例如图4中该第一信息的列表是针对核心网设备发生灾难的情况配置的，即该列表中的第二网络可以在第一网络的核心网设备发生灾难时为终端提供漫游服务，或，该第一信息的列表是针对接入网设备发生灾难的情况配置的，即该列表中的第二网络可以在第一网络的接入网设备发生灾难时为终端提供漫游服务。
例如图7中该第一信息的列表中分别包括针对核心网设备发生灾难时提供灾难漫游服务的第二网络，以及针对接入网设备发生灾难时提供灾难漫游服务的第二网络，图7中RAN灾难条件下第二网络列表长度、CN灾难条件下第二网络列表长度即为第一指示信息。
可选地，在其他实施例中，第一指示信息也可以设置在如图6中的编码格式中。
上述实施方式中，可以通过多种形式实现第一信息的编码，灵活性较大，实现复杂度较低。
可选地，该方法还包括：
接入网设备基于第一信息，确定提供灾难漫游服务的第二网络。
具体地，例如在第一网络处于灾难条件下，接入网设备基于第一信息，确定为终端提供漫游服务的第二网络，可以使得在终端不感知的情况下进行网络选择。
例如第一网络的核心网设备发生灾难，接入网设备在监测到第一网络的核心网设备发生灾难，或通过其他网络的核心网设备发送的消息获知到第一网络的核心网设备发生灾难。
进一步地，接入网设备向终端发送第二信息；第二信息包括：第二网络的网络标识和/或目标指示信息，目标指示信息用于指示与第一网络处于灾难条件相关的信 息。
具体地，终端在接收到第二信息可以接入第二网络，在该过程中可以不显示给用户，使得用户不感知。
可选地，目标指示信息用于指示以下至少一项：
第一网络处于灾难条件；
终端接入第二网络；
终端选择与第一网络不同的网络或执行网络选择；
终端本地去注册第一网络；
终端执行从第一网络向第二网络切换的过程或第一网络与第二网络的互操作过程；
终端进入空闲态。
示例性地，如图8所示，该方法包括：
步骤0、Op1为RAN配置第一信息的列表。
步骤1、Op1发生CN灾难。
步骤2、RAN获知Op1发生CN灾难。
步骤3、基于第一信息的列表，RAN为终端选择一个提供灾难漫游服务的PLMN。如果不需要终端确定是否无其他PLMN可用，那么RAN直接根据第一信息的列表为终端选择一个灾难漫游的网络。选择好以后，RAN把选择的PLMN ID和/或目标指示信息发给终端。
步骤4、终端通过RAN接入Op2CN。
上述实施方式中，在第一网络处于灾难条件时能够为终端选择合适的网络接入，从而实现灾难漫游。
可选地，在接入网设备为终端选择提供漫游服务的网络之前，该方法还可以包括：
接入网设备确定终端无可用网络，可用网络为终端的非禁止网络。
具体地，通常在第一网络发生灾难，且终端无可用网络的情况下，可以进行选网，即确定可以为终端提供漫游服务的网络。
本申请实施例中所描述的终端无可用网络，也可以表述为终端除了禁止的PLMN以外无其他可用网络。
接入网设备对终端是否有无可用网络是未知的，因此接入网设备需要确定终端是否无可用网络，例如接入网设备可以从核心网设备处获知该信息，从网管处获知该信息，或，通过与终端的交互获取到该信息。
非禁止网络即不属于终端的禁止网络列表(forbidden PLMN list)，也可以说不是终端的禁止PLMN。
可选地，确定终端无可用网络，可以通过如下几种方式实现：
一种方式：
为了使得终端无感知，接入网设备可以获取第二指示信息，第二指示信息用于指示以下至少一项：
终端无可用网络；
所有与第一网络不同的网络都处于灾难条件；
接入网设备基于第二指示信息，确定终端无可用网络。
具体地，第二指示信息可以是从核心网设备获取的，可选地，可以从非消息层面(例如，网管通知)获取到。
另一种方式：
如图9所示，接入网设备向终端发送第三信息，第三信息与第一网络处于灾难条件有关；
接入网设备接收终端发送的第四信息，第四信息为第三信息的响应信息；
接入网设备基于第四信息，确定终端无可用网络。
图9中部分步骤与图8所示的实施例类似，此处不再赘述。
第三信息例如可以向通知第一网络处于灾难条件或通知终端可选的网络等信息。
第四信息可以显式或隐式指示终端无可用网络，例如第四信息中携带终端无可用网络的指示信息，或，第四信息即表示终端无可用网络。
在一些实施方式中，终端执行网络选择并确定有其他PLMN可用时，终端驻留到选择的PLMN上，可以不向接入网设备发送响应消息。
可选地，第三信息包括以下至少一项：
第三指示信息，第三指示信息用于指示执行网络选择；
终端的至少一个非禁止网络的信息；
第一测量信息，第一测量信息包括与至少一个网络或小区相关的测量信息；
第四指示信息，第四指示信息用于向终端请求禁止网络信息；
第五指示信息，第五指示信息用于向终端请求第二测量信息，第二测量信息包括至少一个网络或小区的测量信息。
具体地，终端的至少一个非禁止网络的信息，可以用于终端确定执行网络选择的网络。
第一测量信息，用于终端确定网络的质量，例如包括网络或小区相关的参考信号接收功率(Reference Signal Received Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)等测量信息。
第四指示信息用于请求终端发送禁止网络信息，例如终端的禁止网络列表(forbidden PLMN list)。网络侧存储的该终端的禁止网络列表可能与终端处的禁止网络列表有所差异。
第五指示信息用于向终端请求第二测量信息，例如通知终端测量某些小区的信号质量等信息。
可选地，第四信息包括以下至少一项：
第六指示信息，第六指示信息用于指示终端无可用网络；
第二测量信息，第二测量信息包括至少一个网络或小区的测量信息；
终端的禁止网络信息。
具体地，第二测量信息针对的网络或小区与第一测量信息针对的网络或小区可以相同或不同，进一步可以是部分相同或部分不同。
第二测量信息可以用于接入网设备确定网络的网络质量，即可以用于选网。
可选地，接入网设备基于第一信息以及第四信息，确定提供灾难漫游服务的第二网络。
具体地，接入网设备在选择第二网络时可以考虑第二网络的测量信息，例如信号质量，例如可以选择第一信息中优先级较高、信号质量较好的网络，该网络可以是属于终端的禁止网络。
上述实施方式中，接入网设备可以通过从核心网设备处获取到终端无可用网络的信息，或，通过与终端交互获取到终端无可用网络的信息，实现复杂度较低。
可选地，接入网设备向终端发送第三信息之后，还包括：
启动第一计时器，第一计时器与终端有关的上下文有关。
可选地，在第一计时器到期后，接入网设备执行以下至少一项：
释放与终端有关的上下文；
释放与第一网络有关的上下文和/或通信资源；
释放与第二网络有关的上下文和/或通信资源。
可选地，通信资源例如包括空口资源、无线资源控制(Radio Resource Control，RRC)资源、信令无线承载(Signalling Radio Bearer，SRB)、数据无线承载(Data Radio Bearer，DRB)等。
上述实施方式中，通过设置第一计时器，在第一计时器到期后，释放与终端有关的上下文；和/或与网络有关的上下文和/或通信资源，避免资源浪费，提高资源利用效率。
