Description

一种网络异常的处理方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种网络异常的处理方法及装置。
背景技术
随着通信技术的快速发展，4G通信系统已完成大规模铺设，同时兼容2G/3G/4G网络制式的终端越来越多。后续随着5G通信系统的商用化，终端兼容的网络制式也会越来越多，因而终端的兼容性问题也会越来越突出。比如，网络禁止在某些区域使用4G/5G网络、网络不识别4G/5G未开户的终端以及一些网络无法识别的异常情况会时有发生。当发生上述情况时，终端难以自行恢复，也不会切换到其他网络制式，而是会在当前网络制式下不断尝试。
比如，某地区不允许用户使用4G网络，已经开通了4G服务的终端在该地区尝试在4G网络注册时，网络会以15原因值拒绝终端注册。由于该地区的跟踪区(tracking area，TA)可能有多个，因而在用户移动到当前公共陆地移动网络(public land mobile network,PLMN)下的另一TA后，终端会在该TA上再次尝试注册，网络同样会以15原因值拒绝。因而，随着用户在该地区的移动，终端会在当前PLMN下不断尝试注册且不断被网络拒绝。
再比如，在发生网络无法识别的异常情况时，网络会误用13、15等原因值拒绝终端的注册请求或者TA更新请求。在网络异常未恢复的情况下，随着用户的移动，终端会在当前PLMN下不同的TA上不断请求，网络则会以13、15等原因值拒绝终端。
在上述示例中，当发生网络异常情况时，终端在当前PLMN下的不同TA上不断请求，导致终端长时间、无意义的尝试，用户在尝试期间无法获取服务，影响用户体验。
发明内容
本申请实施例提供了一种网络异常的处理方法及装置，用以在发生网络异常事件时提供一种处理方案，避免终端在当前网络制式下长时间、无意义的尝试，提升用户体验。
第一方面，本申请实施例提供一种网络异常的处理方法，该方法包括如下步骤：终端向网络设备发送请求消息，该请求消息用于请求进行注册或跟踪区TA更新；终端记录第一公共陆地移动网络PLMN下发生网络异常事件的次数，网络异常事件为终端发送的请求消息被网络设备以指定原因值拒绝的事件；终端根据发生网络异常事件的次数禁用第一PLMN。
采用上述方案，终端在发生网络异常事件时并不是像现有技术那样被动等待在其他TA上再次尝试，并再次被网络拒绝。而是对发生网络异常事件的次数进行记录，根据发生网络异常事件的次数禁用第一PLMN。在禁用第一PLMN后，可以避免终端在第一PLMN下不同的TA中不断进行无意义的尝试，从而使得终端可以获取网络服务；此外，由于采用上述方案可以减少终端进行无意义的尝试的次数，因而可以降低终端的功耗。
具体实现时，终端禁用第一PLMN可以通过多种方式体现。比如，若发现终端在移动到第一PLMN下的另一个TA后，终端并未按照现有标准流程发起附着请求或注册请求，则可以判断终端已禁用第一PLMN。
此外，在实际应用中，“禁用第一PLMN”也可以替换为其他表述方式，例如“暂停第一PLMN”、“禁止第一PLMN”、“去使能第一PLMN”等，只要执行该操作后可以到达前述禁用第一PLMN的效果，该操作即可视为“禁用第一PLMN”。
具体地，终端根据发生网络异常事件的次数禁用第一PLMN，可通过如下方式实现：终端在发生网络异常事件的次数累计达到第一预设次数的情况下，禁用第一PLMN。
此外，终端根据发生网络异常事件的次数禁用第一PLMN，也可以通过如下方式实现：终端在第一预设时长内发生网络异常事件的次数累计达到第二预设次数的情况下，禁用第一PLMN。
采用上述方案，提供了禁用第一PLMN的两种前提条件。即，终端可以在发生网络异常事件的次数累计到达预设值时禁用第一PLMN，也可以在一定时长内发生网络异常事件的次数累计到达预设值时禁用第一PLMN。无论采用哪种方式，均是基于对网络异常事件的次数的统计结果进行的。
在一种可能的设计中，该方法还包括：终端接收网络设备发送的第一响应消息，该第一响应消息用于指示网络设备拒绝终端的请求，且该第一响应消息携带13原因值；然后，终端可确定发生网络异常事件。
采用上述方案，终端在被网络以13原因值拒绝时认为发生网络异常事件，进而对发生网络异常事件的次数进行统计。
在一种可能的设计中，该方法还包括：终端接收网络设备发送的第二响应消息，该第二响应消息用于指示网络设备拒绝终端的请求，且该第二响应消息携带15原因值；然后，终端可确定发生网络异常事件。
采用上述方案，终端在被网络以15原因值拒绝时认为发生网络异常事件，进而对发生网络异常事件的次数进行统计。
在另一种可能的设计中，该方法还包括：终端接收网络设备发送的第三响应消息，该第三响应消息用于指示网络设备拒绝终端的请求，且该第三响应消息携带13原因值或15原因值；然后，终端可确定发生网络异常事件。
采用上述方案，终端在被网络以13原因值拒绝时或者被网络以15原因值拒绝时均认为发生网络异常事件，进而对发生网络异常事件的次数进行统计。
在一种可能的设计中，在终端根据发生网络异常事件的次数禁用第一PLMN之后，终端还可在当前的第一网络制式下搜网；然后，终端在第一网络制式的第二PLMN下注册；或者，终端可在第一网络制式之外的第二网络制式下搜网；然后，终端在第二网络制式的第一PLMN下注册；其中，第一网络制式为第二网络制式的下一代网络制式。
示例性地，第一网络制式可以为以下任一种：分时长期演进TD-LTE、频分双工长期演进FDD-LTE、5G；第二网络制式可以为以下任一种：全球移动通信系统GSM、码分多址接入CDMA、带宽码分多址接入WCDMA。
采用上述方案，在禁用了第一PLMN后，为终端提供了两种获取网络服务的方式。
此外，在第一方面提供的方法中，在禁用第一PLMN之后，终端还可在第一PLMN被禁用的时间到达第二预设时长的情况下将第一PLMN解禁。
采用上述方案，若网络异常情况在一段时间之后得到解决，则终端可以再次获取第一PLMN的服务。
第二方面，本申请实施例提供一种网络异常的处理装置，该装置包括：发送模块，用 于向网络设备发送请求消息，该请求消息用于请求进行注册或TA更新；记录模块，用于记录第一PLMN下发生网络异常事件的次数，网络异常事件为该装置发送的请求消息被网络设备以指定原因值拒绝的事件；禁用模块，用于根据发生网络异常事件的次数禁用第一PLMN。
在一种可能的设计中，禁用模块在根据发生网络异常事件的次数禁用第一PLMN时，具体用于：在发生网络异常事件的次数累计达到第一预设次数的情况下，禁用第一PLMN。
在另一种可能的设计中，禁用模块在根据发生网络异常事件的次数禁用第一PLMN时，具体用于：在第一预设时长内发生网络异常事件的次数累计达到第二预设次数的情况下，禁用第一PLMN。
在一种可能的设计中，该装置还包括：接收模块，用于接收网络设备发送的第一响应消息，该第一响应消息用于指示网络设备拒绝终端的请求，且该第一响应消息中携带13原因值；确定模块，用于确定发生网络异常事件。
在一种可能的设计中，该装置还包括：接收模块，用于接收网络设备发送的第二响应消息，该第二响应消息用于指示网络设备拒绝终端的请求，且该第二响应消息中携带15原因值；确定模块，用于确定发生网络异常事件。
在一种可能的设计中，该装置还包括：接收模块，用于接收网络设备发送的第三响应消息，该第三响应消息用于指示网络设备拒绝终端的请求，且该第三响应消息中携带13原因值或15原因值；确定模块，用于确定发生网络异常事件。
此外，该装置还包括搜索模块和注册模块。
其中，搜索模块用于在禁用模块根据发生网络异常事件的次数禁用第一PLMN之后，在当前的第一网络制式下搜网；注册模块用于在第一网络制式的第二PLMN下注册。
或者，搜索模块用于在禁用模块根据发生网络异常事件的次数禁用第一PLMN之后，在第一网络制式之外的第二网络制式下搜网；注册模块用于在第二网络制式的第一PLMN下注册；其中，第一网络制式为第二网络制式的下一代网络制式。
示例性地，第一网络制式为以下任一种：TD-LTE、FDD-LTE、5G；第二网络制式为以下任一种：GSM、CDMA、WCDMA。
在一种可能的设计中，该装置还包括解禁模块，用于在禁用模块根据发生网络异常事件的次数禁用第一PLMN之后，在第一PLMN被禁用的时间到达第二预设时长的情况下将第一PLMN解禁。

具体实施方式
如背景技术中所述，同时兼容多种网络制式的终端目前已全面覆盖商用智能终端市场，终端的兼容性问题越来越突出。当发生一些网络异常的情况时，终端难以切换到其他网络制式，而是会在当前网络制式下不断尝试。这无疑会导致终端长时间、无意义的尝试，用户在尝试期间无法获取服务，影响用户体验。
示例性地，一种终端被网络拒绝的流程示意图可以如图1所示。
其中，终端中包含两个模块，2/3G模块和4G模块。其中，2/3G模块负责用户设备在2/3G网络制式下的通信；4G模块负责用户设备在4G网络制式下的通信。具体实现时，2/3G模块和4G模块可以是不同的硬件处理器，也可以是不同的软件处理单元，本申请实施例对此不做具体限定。
在图1所示的流程中，终端搜索到PLMN1下的4G网络并驻留；然后终端通过4G模块向无线网络发送附着请求(ATTACH REQUEST)消息，以请求获取4G网络上的服务；当前地区不支持4G服务，网络判断4G网络在当前TA不可用，会向终端发送附着拒绝(ATTACH REJECT)消息，以15原因值拒绝终端。终端在收到ATTACH REJECT消息后，将当前TA加入禁止列表(Forbidden TA for roaming)中，并尝试搜索PLMN下的其他TA；当用户移动到PLMN1下的另一TA后，终端在新的TA上尝试获取服务，由于当前地区不支持4G服务，因而会重复上述被拒绝的流程。
此外，若图1中的终端已经在4G网络中注册成功，该终端还可能在跟踪区更新的过程中由于网络异常而被无线网络以原因值13或15拒绝。在这种情况下，终端也会在新的TA上不断尝试，并不断被拒绝。
示例性地，另一种终端被网络拒绝的流程示意图可以如图2所示。
其中，终端中包含两个模块，2/3G/4G模块和5G模块。其中，2/3G/4G模块负责用户 设备在2/3G/4G网络制式下的通信；5G模块负责用户设备在5G网络制式下的通信。具体实现时，2/3G/4G模块和5G模块可以是不同的硬件处理器，也可以是不同的软件处理单元，本申请实施例对此不做具体限定。
在图2所示的流程中，终端搜索到PLMN1下的5G网络并驻留；然后终端通过5G模块向无线网络发送注册请求(REGISTRATION REQUEST)消息，以请求获取5G网络上的服务；网络判断5G网络在当前TA不可用，向终端发送注册拒绝(REGISTRATION REJECT)消息，以15原因值拒绝终端。终端在收到REGISTRATION REJECT消息后，将当前TA加入禁止列表(5GS forbidden tracking areas for roaming列表)中，并尝试搜索PLMN下的其他TA；当用户移动到PLMN1下的另一TA后，终端在新的TA上尝试获取服务，重复上述被拒绝的流程。
本申请实施例中，发生网络异常事件的原因可以有多种。比如，某个网络制式在某地区不可用，当终端处于该地区内并尝试获取该网络制式下的服务时，无线网络会以15原因值拒绝终端的请求；再比如，当网络由于未知原因导致无法为终端提供服务时，无线网络会以13原因值或15原因值拒绝终端的请求。
对于由于不支持某种网络制式而导致的网络异常的情况，只有在终端移动到支持该网络制式的地区之后，网络异常的情况才可消除；而对于未知原因导致的网络异常，网络可能可以在一段时间之后自行恢复，也可能无法恢复。
总之，本申请实施例所述的网络异常事件可能难以在短时间内得到解决，终端在不同TA上频繁尝试，仅仅是长时间、无意义的尝试，终端在尝试期间被叫不通、功耗增加，导致用户在尝试期间无法获取网络服务。
针对这一问题，本申请实施例提供一种网络异常的处理方法及装置，用以在发生网络异常事件时提供一种处理方案，避免终端在当前网络制式下长时间、无意义的尝试，提升用户体验。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
下面，首先对本申请实施例的应用场景加以介绍。
本申请实施例可应用于图3所示的通信系统中。该通信系统中包含终端和网络设备。
其中，终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
特别地，本申请实施例中，终端支持多种网络制式。终端支持的网络制式包括但不限于全球移动通信系统(global system for mobile communication，GSM)、码分多址接入(code division multiple access，CDMA)、带宽码分多址接入(wide-band code division multiple access，WCDMA)、时分同步码分多址接入(time division-synchronous code division multiple access，TD-SCDMA)、长期演进(long term evolution，LTE)、第五代(5th generation，5G)通信系统。
其中，网络设备是为终端提供各种网络制式下的服务的设备。具体地，网络设备可以是核心网(Core)中的设备。具体地，网络设备可以负责维护移动网络的签约数据、管理移动网络的网元，并为终端提供会话管理、移动性管理、策略管理、安全认证等功能。例如，在终端附着的时候，为终端提供入网认证；在终端有业务请求时，为终端分配网络资源；在终端移动的时候，为终端更新网络资源；在终端空闲的时候，为终端提供快恢复机制；在终端去附着的时候，为终端释放网络资源；在终端有业务数据时，为终端提供数据路由功能。
此外，本申请实施例中，终端与网络设备的交互可以通过接入网(access network，AN)进行。AN可以理解为传统通信网络里面的基站，部署在靠近终端的位置，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、业务的需求等确定不同质量的传输隧道来传输用户数据。
下面将结合附图对本申请实施例作进一步地详细描述。
需要说明的是，本申请实施例中，多个是指两个或两个以上。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
参见图4，为本申请实施例提供的一种网络异常的处理方法。该方法包括如下步骤。
S401：终端向网络设备发送请求消息。
其中，该请求消息用于请求进行注册或TA更新。
示例性地，该请求消息可以是附着请求(ATTACH_REQUEST)消息、跟踪区更新请求(TAU_REQUEST)消息或者注册请求(REGISTRATION REQUEST)消息。
S402：终端记录第一PLMN下发生网络异常事件的次数。
其中，网络异常事件为终端发送的请求消息被网络设备以指定原因值拒绝的事件。也就是说，网络异常事件为终端接收到网络设备发送的、以指定原因值拒绝该请求消息的事件。例如，网络设备以15原因值拒绝终端的注册请求或者附着请求可以视为网络异常事件；或者，网络设备以13原因值或者15原因值拒绝终端的跟踪区更新请求也可以视为网络异常事件。
在移动通信系统中，终端开机后需要选择一个PLMN并驻留到该PLMN下的一个小区中完成网络注册，然后才能执行正常的呼叫或会话业务，例如语音通话、数据传输等。其中，对于一个PLMN来说，该PLMN可以支持多种网络制式，且该PLMN通常覆盖多个TA。比如，终端在4G网络下进行搜网后，可以驻留到第一PLMN下的某一TA，也可以驻留到另一PLMN下的某一TA；再比如，终端在5G网络下进行搜网后，可以驻留到第一PLMN下的某一TA，也可以驻留到另一PLMN下的某一TA。
具体实现时，终端在确定发生网络异常事件后可以对网络异常事件的次数进行累计。其中，根据指定原因值的不同，终端可以采用多种方式确定发生网络异常事件。
方式一
终端接收网络设备发送的第一响应消息，第一响应消息用于指示网络设备拒绝请求消息，且第一响应消息携带13原因值；然后，终端确定发生网络异常事件。
也就是说，每当终端发送的请求消息被网络设备以13原因值拒绝时，终端认为发生网络异常事件。
在方式一中，终端可以将接收到的携带13原因值的第一响应消息的个数视为发生网络异常事件的次数。
方式二
终端接收网络设备发送的第二响应消息，第二响应消息用于指示网络设备拒绝请求消息，且第二响应消息携带15原因值；然后，终端确定发生网络异常事件。
也就是说，每当终端发送的请求消息被网络设备以15原因值拒绝时，终端认为发生网络异常事件。
在方式二中，终端可以将接收到的携带15原因值的第二响应消息的个数视为发生网络异常事件的次数。
方式三
终端接收网络设备发送的第三响应消息，第三响应消息用于指示网络设备拒绝请求消息，且第三响应消息携带13原因值或15原因值；然后，终端确定发生网络异常事件。
也就是说，每当终端发送的请求消息被网络设备以13原因值拒绝时或者被网络设备以15原因值拒绝时，终端均认为发生网络异常事件。
在方式三中，终端可以将接收到的携带13原因值的第三响应消息的个数与接收到的携带15原因值的第三响应消息的个数之和，视为发生网络异常事件的次数。
S403：终端根据发生网络异常事件的次数禁用第一PLMN。
具体实现时，S403中终端根据发生网络异常事件的次数禁用第一PLMN可以有多种实现方式。
比如，终端可以在发生网络异常事件的次数累计达到第一预设次数的情况下，禁用第一PLMN。
在这种情况下，终端仅对发生网络异常事件的次数进行累计即可。
再比如，终端可以在第一预设时长内发生网络异常事件的次数累计达到第二预设次数的情况下，禁用第一PLMN。
在这种情况下，终端除了对发生网络异常事件的次数进行记录以外，还可同时记录网络异常事件的发生时间，从而对不同时间点发生的网络异常事件进行统计，并在满足上述条件时禁用第一PLMN。或者，终端可仅记录发生网络异常事件的次数，且终端在第一次发生网络异常事件时启动定时器，该定时器的定时时长为第一预设时长。那么，终端可以在定时器未超时的情况下判断发生网络异常事件的次数是否达到第二预设次数，若达到，则禁用第一PLMN。
在上述示例中，第一预设次数、第二预设次数和第一预设时长均可以根据应用场景和用户需求进行设置，其具体数值在本申请实施例中不做限定。
不难看出，在图4所示的方法中，终端在发生网络异常事件时并不是像现有技术那样被动等待在其他TA上再次尝试，并再次被网络拒绝。而是对发生网络异常事件的次数进行记录，根据发生网络异常事件的次数禁用第一PLMN。在禁用第一PLMN后，可以避免终端在第一PLMN下不同的TA中不断进行无意义的尝试，从而使得终端可以获取网络服务；此外，由于采用上述方案可以减少终端进行无意义的尝试的次数，因而可以降低终端的功耗。
此外，在终端禁用第一PLMN之后，终端可以执行一些操作，以使得终端获取到网络服务。
具体地，终端可以在当前的第一网络制式下搜网；然后，终端根据搜网结果在第一网络制式的第二PLMN下注册。这样的话，终端不必在第一PLMN的不同TA进行尝试，而是驻留到第二PLMN，终端可以在第二PLMN中获取第一网络制式下的服务。
具体地，终端还可以在第一网络制式之外的第二网络制式下搜网；然后，终端根据搜网结果在第二网络制式的第一PLMN下注册。这样的话，终端不必在第一PLMN的不同TA进行尝试，而是驻留到第二网络制式下的第一PLMN，终端可以在第一PLMN中获取第二网络制式下的服务。
其中，第一网络制式为第二网络制式的下一代网络制式。具体地，第一网络制式为以下任一种：TD-LTE、FDD-LTE、5G；第二网络制式为以下任一种：GSM、CDMA、WCDMA。
示例性地，第一网络制式可以是5G，那么第二网络制式可以是TD-LTE、FDD-LTE、GSM、CDMA、WCDMA中的任一种。
示例性地，第一网络制式可以是TD-LTE和FDD-LTE中的一种，那么第二网络制式可以是GSM、CDMA、WCDMA中的任一种。
此外，本申请实施例中，终端在S403中在禁用第一PLMN之后，还可以在第一PLMN被禁用的时间到达第二预设时长的情况下将第一PLMN解禁。
其中，第二预设时长可以根据应用场景和用户需求进行设置，其具体数值在本申请实施例中不做限定。
将第一PLMN解禁以后，终端可以重新驻留第一PLMN，并重新尝试获取第一网络制式下的第一PLMN的服务。
此外，终端还可以在其他条件下对第一PLMN进行解禁。例如，终端可以在接收到用户的指示后将第一PLMN解禁。
如前所述，本申请实施例中，网络异常的情况有可能在一段时间之后得到解决，因而执行前述解禁第一PLMN的操作，可以在一段时间之后给予终端再次在第一网络制式下的第一PLMN进行尝试的机会。若此时网络异常的情况已经得到解决，则终端可以再次获取第一网络制式下的第一PLMN的服务。
当然，若网络异常的情况未得到解决，那么终端将第一PLMN解禁之后，还是可以通过图4所示的方法再次将第一PLMN禁用。虽然这种情况下相当于又进行了一次无意义的尝试，但是该方案与现有技术中一直驻留在第一PLMN并在不同TA上进行尝试的方案相比，仍然可以减少终端的尝试次数；在禁用第一PLMN的期间，终端可以获取网络服务，从而提升用户体验。
具体实现时，终端中可以部署有不同的功能模块，通过各个模块相互配合来实现图4所示的方法。具体地，终端中用于执行图4所示方法的功能模块可以采用图5所示的部署方式。
其中，本地配置模块：用于配置被网络以13/15原因值拒绝这一场景的识别条件，在发生被网络拒绝的情况时，为识别模块提供判断依据。例如，本地配置模块中可以配置在多长时间内以13/15原因被拒多少次等识别条件。
识别模块：当被网络拒绝时判断是否需要记录相关情况，并根据本地配置模块输出的识别条件判断是否需要输出识别结果。比如，在预设时长内以13/15原因被拒的次数达到本地配置模块配置的次数时，识别模块将识别结果输出。
记录模块：用于保存网络异常事件发生的次数，将本地记录反馈给识别模块。此外，记录模块还可以对网络异常事件的发生时间进行记录，以供识别模块判断是否需要输出识别结果。
逃生策略模块：用于根据识别模块的识别结果进行相应的逃生操作，如禁用PLMN。
恢复策略模块：用于在执行逃生操作之后判断是否进行恢复，如禁用PLMN后判断是否需要解除禁用。

同样需要说明的是，网络异常的处理装置900可用于执行图4对应的实施例提供的方法终端所执行的操，因此图9所示的网络异常的处理装置900中未详尽描述的实现方式及技术效果可参见图4中的相关描述。
基于相同构思，本申请实施例还提供一种网络异常的处理装置，该装置应用于终端，该网络异常的处理装置用于执行图4所示的网络异常的处理方法中终端所执行的操作，可以是与图9所示的网络异常的处理装置900相同的装置。

在下行链路上，通过天线接收网络设备(例如基站)发送的下行链路信号(包括数据和/或控制信息)，在上行链路上，通过天线向网络设备(例如基站)发送上行链路信号(包括数据和/或控制信息)，在处理器中，对业务数据和信令消息进行处理，这些单元根据无线接入网采用的无线接入技术(例如，LTE、NR及其他演进系统的接入技术)来进行处理。所述处理器还用于对网络异常的处理装置1000的动作进行控制管理，用于执行上述实施例中由网络异常的处理装置1000进行的处理。处理器还用于支持网络异常的处理装置1000执行图4中终端的执行方法。
可以理解的是，图10仅仅示出了网络异常的处理装置1000的简化设计。在实际应用中，网络异常的处理装置1000可以包含任意数量的天线，存储器，处理器等，而所有可以实现本申请的网络异常的处理装置1000都在本申请的保护范围之内。
具体地，本申请中，以收发单元称为收发器，处理单元称为处理器为例，则网络异常的处理装置1000在执行图4所示的网络异常的处理方法时，收发器向网络设备发送请求消息，该请求消息用于请求进行注册或TA更新；处理器记录第一PLMN下发生网络异常事件的次数，网络异常事件为装置1000发送的请求消息被网络设备以指定原因值拒绝的事件；以及，根据发生网络异常事件的次数禁用第一PLMN。
处理器还可以实现上述图4所示的方法实施例中终端的任意详细功能，在此不再详尽赘述，可以参照上述图4所示的方法实施例中终端执行的处理步骤。
需要说明的是，图9～图10中所示的网络异常的处理装置可视为终端中的集成芯片，也可以也视为终端。
具体地，该终端包括但不限于智能手机、智能手表、平板电脑、VR设备、AR设备、个人计算机、手持式计算机、个人数字助理。
本领域内的技术人员应明白，本申请的实施例可提供为方法、系统、或计算机程序产品。因此，本申请可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本申请可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本申请是参照根据本申请实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。

显然，本领域的技术人员可以对本申请实施例进行各种改动和变型而不脱离本申请实施例的精神和范围。这样，倘若本申请实施例的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
