Description

一种通信方法、装置、可读存储介质和芯片系统 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置、可读存储介质和芯片系统。
背景技术
从3G制式开始，第三代合作伙伴计划(3rd generation partnership project，3GPP)协议中引入了双向鉴权操作，在终端设备完成与基站间的双向鉴权并进入连接态之前，基站仅能向终端设备发送系统消息、寻呼消息等消息，无法获取到终端设备的相关信息。
由于伪基站无法获取网络侧的鉴权信息，因而伪基站无法完成与终端设备间的双向鉴权。因此，在现网中，为了获取终端设备的相关信息，伪基站通常会诱导长期演进(long term evolution，LTE)等制式下的终端设备进行小区重选或重定向，使得终端设备驻留到伪基站小区。当终端设备驻留到伪基站的小区后，发起跟踪区更新(Track Area Update，TAU)。伪基站在查询用户国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)后向终端设备发送TAU拒绝，或者直接释放用户无线资源控制(Radio Resource Control，RRC)链路连接。
当终端设备在驻留的伪基站执行LTE网络语音业务(Voice over Long Term Evolution，VoLTE)业务，由于伪基站向终端设备发送TAU拒绝或直接释放用户RRC链路连接，因此会导致VoLTE业务失败。
举个例子，用户在伪基站发起VoLTE业务，由于伪基站向终端设备发送TAU拒绝或直接释放用户RRC链路连接，因此会导致VoLTE业务的发起失败，在终端设备的界面上展示电话发起失败的信息，用户实际体验到的是呼叫未接通。
发明内容
本申请提供一种通信方法、装置、可读存储介质和芯片系统，用于在遭遇伪基站攻击的情况下可以实现语音业务的恢复。
第一方面，本申请提供一种用于无线通信装置的方法，该方法中，无线通信装置在第一小区执行语音业务失败；执行伪网络设备识别策略，在识别第一小区所属的第一网络设备为伪网络设备的情况下：接入第二小区，在第二小区尝试进行语音业务。由于执行了伪网络设备识别策略，因此当语音业务失败时可以判断是否是因为第一网络设备为伪网络设备的原因导致的。若是由于第一网络设备为伪网络设备所导致的，则并不会因为语音业务在第一小区执行失败而结束该语音业务，而是接入第二小区继续尝试进行语音业务，从而可以在遭遇伪基站攻击的情况下实现语音业务的恢复。
应理解，本申请实施例提供的方案中，无线通信装置可以是无线通信设备，也可以是无线通信设备中的部分器件，如系统芯片或通信芯片等集成电路产品。无线通信设备可以是支持无线通信功能的计算机设备。
具体地，无线通信设备可以是诸如智能手机这样的终端，也可以是诸如基站这样的无线接入网设备。系统芯片也可称为片上系统(system on chip，SoC)，或简称为SoC芯片。通信芯片可包括基带处理芯片和射频处理芯片。基带处理芯片有时也被称为调制解调器(modem)或基带芯片。射频处理芯片有时也被称为射频收发机(transceiver)或射频芯片。 在物理实现中，通信芯片中的部分芯片或者全部芯片可集成在SoC芯片内部。例如，基带处理芯片集成在SoC芯片中，射频处理芯片不与SoC芯片集成。
无线通信装置在第一小区执行语音业务具体来说可以包括多种应用场景，比如下述场景一中，无线通信装置在第一小区发起语音业务。比如，下述场景二中，无线通信装置在除第一小区之外的小区，比如第三小区发起语音业务，在语音业务的进行过程中切换至第一小区。下面分别对这两种场景进行介绍。
在一种可能地实施方式中，针对上述场景一，在第一小区执行语音业务失败，包括：接收来自第一网络设备的系统消息，从而驻留至第一小区。在第一小区接收用户输入的第一操作信息。第一操作信息用于指示用户发起语音业务。基于第一操作信息在第一小区发送第一消息，第一消息用于请求跟踪区更新或位置区更新。接收来自第一小区所属的第一网络设备的第二消息，第二消息用于指示跟踪区更新失败，或位置区更新失败。通过该方案可以看出，该场景下，用户在第一小区需要发起主叫的语音通话，基于用户的第一操作信息(比如可以是用户的拨号的操作)，无线通信装置发起跟踪区更新流程或位置区更新流程，结果更新失败。因为跟踪区或位置区更新失败，因此导致无法在第一小区成功执行语音业务，即该语音业务失败。
进一步，在一种可能地实施方式中，当接收到第二消息，无线通信装置通过显示屏显示第一显示信息，第一显示信息用于指示语音业务对应的语音通话处于待接通状态。可见，本申请中，当语音业务失败时，也并不会在无线通信装置界面上显示通话失败的信息，如此，则用户在此刻并不会感知语音业务执行失败的事情，如此，可以为后续语音业务的接续奠定基础。
在一种可能地实施方式中，当第一网络设备为伪网络设备的情况下，无线通信装置接收来自第二小区所属的第二网络设备的系统消息；基于第一操作信息，在第二小区发送会话邀请消息，会话邀请消息用于发起语音业务。可以看出，本申请中并不是基于在第一小区执行语音业务失败而结束该语音业务，而是在第一网络设备为伪网络设备的情况下，在接入的第二小区继续尝试进行语音业务，从而可以实现语音业务的接续。
在一种可能地实施方式中，第一网络设备为伪网络设备的情况下：在第一时间段内，无线通信装置通过显示屏显示的信息为第一显示信息；其中，第一时间段的起始点：早于接收到第二消息的时间点；第一时间段的终止点：晚于发送会话邀请消息的时间点。也就是说，本申请中当语音业务在第一小区发起失败时，并不会显示语音业务失败的信息，而是在显示屏上继续显示语音通话处于待接通状态的信息，用户并不感知在该过程中出现了语音业务执行失败的情况。直至在第二小区发送会话邀请消息后，可以根据具体语音业务是否成功来切换显示屏上的信息。
在一种可能地实施方式中，针对上述场景二，无线通信装置驻留在第三小区，并在第三小区进行语音业务。在语音业务执行过程中，驻留至第一小区，在第一小区发送第一消息，第一消息用于请求跟踪区更新或位置区更新。接收来自第一小区所属的第一网络设备的第二消息，第二消息用于指示跟踪区更新失败，或位置区更新失败。通过该方案可以看出，该场景下，用户在第三小区已经成功发起语音业务，且在语音业务过程中驻留至第一小区，无线通信装置在第一小区发起跟踪区更新流程或位置区更新流程，结果更新失败。因为跟踪区或位置区更新失败，因此导致无法在第一小区执行语音业务，即该语音业务失败。
进一步，一种可能地实施方式中，当接收到第二消息，无线通信装置通过显示屏显示第二显示信息，第二显示信息用于指示语音业务对应的语音通话处于接通状态。可见，本申请中，当语音业务失败时，也并不会在无线通信装置界面上显示通话失败的信息，如此，则用户在此刻并不会感知语音业务执行失败的事情，如此，可以为后续语音业务的接续奠定基础。
进一步，一种可能地实施方式中，当第一网络设备为伪网络设备的情况下，无线通信装置接收来自第二小区所属的第二网络设备的系统消息，从而驻留至第二小区。接收第一无线资源控制RRC重配置请求消息，第一RRC重配置请求消息用于请求为语音业务配置数据资源承载；在第二小区发送第一RRC重配置完成消息。如此，可以通过第一RRC重配置请求消息和第一RRC重配置完成消息为该语音业务配置数据资源承载，为继续执行该语音业务奠定基础。一种可能地实施方式中，第二网络设备可以从网络侧获取该语音业务的相关信息，继而发送第一RRC重配置请求消息。或者，第二网络设备可以在发送第一RRC重配置请求消息之前，接收来自无线通信装置侧的消息(比如跟踪区更新请求、位置区更新请求或服务请求消息等)，从而获得该语音业务的相关信息，继而发送第一RRC重配置请求消息。
一种可能地实施方式中，第一网络设备为伪网络设备的情况下：在第二时间段内，无线通信装置通过显示屏显示的信息为第二显示信息，第二显示信息用于指示语音业务对应的语音通话处于接通状态。其中，第二时间段的起始点为：在第三小区发起的语音业务对应的语音通话处于接通状态的时间点；第二时间段的终止点：晚于发送第一RRC重配置请求消息的时间。也就是说，本申请中当语音业务在第一小区发起失败时，并不会显示语音业务失败的信息，而是在显示屏上继续显示语音通话处于待接通状态的信息，用户并不感知在该过程中出现了语音业务执行失败的情况。直至在第二小区发送会话邀请消息后，可以根据具体语音业务是否成功来切换显示屏上的信息。
一种可能地实施方式中，在场景二中，无线通信装置可以为主叫方，也可以为被叫方。当其为主叫方时，无线通信装置可以接收用户输入的第一操作信息，第一操作信息用于指示发起语音业务；基于第一操作信息，在第三小区发送会话邀请消息，会话邀请消息用于发起语音业务。当其为被叫方时，无线通信装置可以在第三小区接收寻呼消息，寻呼消息用于指示无线通信装置发起语音业务。
一种可能地实施方式中，针对上述场景一或场景二，在识别第一小区所属的第一网络设备并非伪网络设备的情况下：无线通信装置通过显示屏上显示的信息为第三显示信息，第三显示信息用于指示语音业务对应的语音通话处于结束状态。与之想对比的是，当第一网络设备为伪网络设备的情况下，无线通信装置通过显示屏显示的信息为第一显示信息或第二显示信息，第一显示信息和第二显示信息均指示语音通话并未结束，从而可以使用户感受不到语音业务执行失败这个事件的发生。
一种可能地实施方式中，针对上述场景一或场景二，第二消息还包括第一指示信息，第一指示信息用于指示无线通信装置执行附着流程。在识别第一小区所属的第一网络设备并非伪网络设备的情况下：基于第一指示信息，执行附着流程。而与之想对比的是，当第一网络设备为伪网络设备的情况下，虽然接收到了第一指示信息，但是无线通信装置并不会执行附着流程，而是接入第二小区，并尝试进行语音业务。
一种可能地实施方式中，针对上述场景一或场景二，基于第一指示信息，执行附着流 程，包括：在第二小区发送附着请求；接受第二小区所属的第二网络设备发送的附着接受；在第二小区发送附着完成。
一种可能地实施方式中，针对上述场景一或场景二，第一指示信息包括：#9、#10或#40中的一项拒绝原因值。

具体实施方式
下面将结合附图，对本申请实施例进行详细描述。

基于上述内容，图2示例性示出了本申请实施例提供的一种通信方法的流程示意图，如图2所示，该方法包括：
步骤S201，无线通信装置在第一小区执行语音业务失败；
步骤S202，无线通信装置在识别第一小区所属的第一网络设备为伪网络设备的情况下：接入第二小区，在第二小区尝试进行语音业务。
一种可能地实施方式中，步骤S202中，无线通信装置可以执行伪网络设备识别策略，以识别第一网络设备是否为伪网络设备，在识别第一网络设备为伪网络设备的情况下：接入第二小区，在第二小区进行语音业务。
需要说明的是，第一小区为第一网络设备下的一个小区，第二小区为第二网络设备下的一个小区，第一网络设备和第二网络设备为两个不同的网络设备。
在上述步骤S201中，无线通信装置在第一小区执行语音业务具体来说可以包括多种应用场景，比如下述场景一中，无线通信装置在第一小区发起语音业务。比如，下述场景二中，无线通信装置在除第一小区之外的小区，比如第三小区发起语音业务，在语音业务的进行过程中切换至第一小区。下面分别对这两种场景进行介绍。
场景一，无线通信装置在第一小区发起语音业务。
基于上述内容，图3a示例性示出了本申请实施例提供的场景一的一种通信方法的流程示意图，如图3a所示，该方法包括：
步骤S301，用户在无线通信装置的显示屏上进行操作，以输入第一操作信息。
在步骤S301中，用户进行的操作比如可以为向被叫发起语音呼叫的操作。第一操作信息用于指示发起语音业务。
步骤S302，无线通信装置基于用户输入的第一操作信息的触发，在显示屏上显示第一显示信息，第一显示信息用于指示语音业务对应的语音通话处于待接通状态。
步骤S303，无线通信装置在第一小区发送第一消息，第一消息用于请求位置更新。
本申请实施中，第一消息可以为跟踪区更新请求消息或位置区更新请求消息。其中，跟踪区更新请求消息可以为track area update request，也可以写为TAU_REQ。位置区更新请求消息可以为location area update request，也可以写为LAU_REQ。
一种可能地实施方式中，无线通信装置从其他网络设备切换至第一网络设备，无线通信装置的协议栈的模块准备发起服务请求消息以建立链接时，发现无线通信装置所接收到的系统消息进行了变化，也可以说发现无线通信装置从其他小区(比如可能是第三小区)驻留至了第一小区，这种情况下，无线通信装置可以不再发送服务请求消息，而是发送跟踪区更新请求消息或位置区更新请求消息，以便与网络设备之间建立链接。这种实施方式 下，无线通信装置可以发送上述步骤S303中的第一消息。
步骤S304，无线通信装置接收来自第一网络设备的第二消息，第二消息用于指示位置更新失败，无法在第一小区执行语音业务。
第二消息可以为跟踪区更新拒绝消息或位置区更新拒绝消息。其中，跟踪区更新拒绝消息可以为track area update rejected，也可以写为TAU_REJ。位置区更新拒绝消息可以为location area update rejected，也可以写为LAU_REJ。
在一种可能地实施方式中，可以在第二消息中携带第一指示信息。第一指示信息可以用于指示拒绝原因值。拒绝原因值可以为多种可能，比如拒绝原因值可以为：#13、#15、#9和#10等等。
其中，当拒绝原因值为#13，则表示该跟踪区不允许漫游(Roaming not allowed in this tracking area)。当拒绝原因值为#15，则表示该跟踪区没有合适小区(No suitable cells in tracking area)。当拒绝原因值为#9，则表示无线通信装置的标识在网络中不存在(UE identity cannot be derived by the network)。当拒绝原因值为#10，则表示隐式分离(Implicitly detached)。当拒绝原因值为#40，则表示没有演进的分组系统(Evolved Packet System，EPS)承载上下文被激活(No EPS bearer context activated)。
通过上述步骤S301至步骤S304，可以确定无线通信装置在第一小区执行语音业务失败。也可以理解为上述步骤S303至步骤S304的方案为步骤S201的一种可能的实施方式。
步骤S305，无线通信装置执行伪网络设备识别策略，识别第一小区所属的第一网络设备是否为伪网络设备；
若是，则可以执行步骤S306和步骤S307；若否，则可以执行步骤S308；
步骤S306，无线通信装置接入第二小区，在第二小区进行语音业务。
在上述步骤S305中，无线通信装置可以通过执行伪网络设备识别策略来进行判断。伪网络设备的识别策略有多种：
比如，在进行系统消息配置时，合法网络设备和伪网络设备的配置会有所不同。第一网络设备在进行系统消息配置时，会向无线通信装置下发共享公共陆上移动网(Public Land Mobile Network，PLMN)列表，以指示无线通信装置的PLMN标识为该列表中的任一个时，无线通信装置均可与第一网络设备建立RRC连接。而无线通信装置中也维护有一个PLMN列表，该列表指示哪些PLMN不可由一个网络设备共享，例如移动运营商的PLMN1和电信运营商的PLMN2不可被一个网络设备共享。无线通信装置在收到第一网络设备下发的共享PLMN列表后，可以将该共享PLMN列表与自身维护的PLMN列表比照，若该共享PLMN列表中包含至少两个不可被一个网络设备共享的PLMN，则无线通信装置认为该第一网络设备为伪网络设备。这是因为：伪网络设备通常会将多个运营商的PLMN标识配置在一个共享PLMN列表中，以诱导更多的无线通信装置与自身建立RRC连接。
比如，合法网络设备会配置异频邻区和/或异系统邻区，而伪网络设备通常不会配置异频邻区和异系统邻区。
比如，伪网络设备配置的驻留门限通常较低，使得伪网络设备的发射功率较低时，无线通信装置根据该伪网络设备的驻留门限判断时也能判断满足驻留条件，以诱导无线通信装置驻留，而合法网络设备配置的驻留门限通常高于伪网络设备配置的驻留门限。
再比如，伪网络设备通常会将全球移动通信系统(global system for mobile communication，GSM)邻区配置为高重选优先级。这是因为：GSM没有双向鉴权，无线 通信装置驻留在GSM伪网络设备小区上的危害更大(用户隐私泄露、发送垃圾短信)。伪网络设备通常将GSM邻区配置为高重选优先级，可以让无线通信装置更易重选到GSM伪网络设备小区。且现网中合法网络设备通常将GSM邻区配置为低重选优先级，避免重选到速率较低的GSM小区。
在上述实现方式中，可以通过识别第一网络设备的系统消息配置是否体现有伪网络设备的系统消息配置的特点，来判断第一网络设备是否为伪网络设备。即，通过第一网络设备的系统消息配置情况可判断第一网络设备是否为伪网络设备。
在一种可能地实施方式中，在上述步骤S306之后，当确定第一网络设备为伪网络设备后，无线通信装置可将第一小区的小区信息加入受限列表，该受限列表用于指示无线通信装置禁止驻留在该受限列表中记录的小区信息所对应的小区。第一小区的小区信息包括以下至少一种：第一小区的小区频点；第一小区的小区频段；第一小区的物理小区标识(physical cell ID，PCI)、第一小区的E-UTRA绝对无线频率信道号(E-UTRA absolute radio frequency channel number，EARFCN)、小区对应的跟踪区(track area，TA)标识等。需要说明的是，第一小区的小区信息不限于上述几种，只要该第一小区的小区信息可用于标识第一小区即可。
步骤S307，当该语音业务对应的语音呼叫被被叫方接听后，则无线通信装置在显示屏上显示第二显示信息，第二显示信息用于指示语音业务对应的语音通话处于接通状态。
一种可能地实施方式中，也可以理解为：当该语音业务对应的语音呼叫被被叫方接听后，无线通信装置将显示屏上显示的信息从第一显示信息更新为第二显示信息。
一种可能地实施方式中，当接收到第二消息，无线通信装置的显示屏显示第一显示信息而并不是第三显示信息，第一显示信息用于指示语音业务对应的语音通话处于待接通状态。
又一种可能地实施方式中，第一网络设备为伪网络设备的情况下，无线通信装置的显示屏在第一时间段内显示的信息为第一显示信息。其中，第一时间段的起始点：早于接收到第二消息的时间点。比如，第一时间段的起始点可以为接收到用户输入的第一操作信息的时间点。第一时间段的终止点：晚于发送会话邀请消息的时间点。也就是说在整个第一时间段内，无线通信装置均显示第一显示信息，即使在第一时间段内，无线通信装置驻留了伪网络设备，无线通信装置也不会再第一时间段显示语音业务结束(或者说失败、中断等)的相关信息。
步骤S308，无线通信装置确定语音业务执行失败，无线通信装置在显示屏上显示第三显示信息，第三显示信息用于指示语音业务对应的语音通话处于结束状态。
一种可能地实施方式中，也可以理解为：当无线通信装置确定语音业务执行失败后，无线通信装置将显示屏上显示的信息从第一显示信息更新为第三显示信息。
步骤S308中，一种可能地实施方式中，当无线通信装置接收到的来自第一网络设备的拒绝原因值时，可以根据拒绝原因值执行相应的动作。拒绝原因值可以携带在上述第二消息中，也可以携带在其他消息中。
在一种可能地实施方式中，可以在第二消息中携带拒绝原因值。拒绝原因值可以为多种可能，比如拒绝原因值可以为：#13、#15、#9、#10或#40等等。
其中，当拒绝原因值为#13，则表示该跟踪区不允许漫游(Roaming not allowed in this tracking area)。当无线通信装置接收到该拒绝原因值，则无线通信装置应将当前TAI存储 在“禁止漫游跟踪区”列表中，并进入无注册(EMM-DEREGISTERED)，或限制服务
(LIMITED-SERVICE)状态，接着无线通信装置应执行PLMN选择。当无线通信装置接收到该拒绝原因值#13，则无线通信装置所需执行的动作的对应英文可以为：
the UE shall store the current TAI in the list of"forbidden tracking areas for roaming".Additionally,the UE shall enter the state EMM-DEREGISTERED.LIMITED-SERVICE or optionally EMM-DEREGISTERED.PLMN-SEARCH。
The UE shall perform a PLMN selection。
其中，当拒绝原因值为#15，则表示该跟踪区没有合适小区(No suitable cells in tracking area)。当无线通信装置接收到该拒绝原因值，则无线通信装置应将当前TAI存储在“禁止漫游跟踪区”列表中，并进入无注册(EMM-DEREGISTERED)，或限制服务(LIMITED-SERVICE)状态，接着无线通信装置应在另一个跟踪区域或另一个位置区域搜索合适的小区。当无线通信装置接收到该拒绝原因值#15，则无线通信装置所需执行的动作的对应英文可以为：
store the current TAI in the list of"forbidden tracking areas for roaming"and enter the state EMM-DEREGISTERED.LIMITED-SERVICE。
the UE shall search for a suitable cell in another tracking area or in another location area。
其中，当拒绝原因值为#9，则表示无线通信装置的标识在网络中不存在(UE identity cannot be derived by the network)。当无线通信装置接收到该拒绝原因值#9，则：需要随后执行附着流程。当无线通信装置接收到该拒绝原因值#9，则无线通信装置所需执行的动作的对应英文可以为：
UE shall subsequently,automatically initiate the attach procedure。
其中，当拒绝原因值为#10，则表示隐式分离(Implicitly detached)。当无线通信装置接收到该拒绝原因值#10，则：如果被拒绝的请求不是为紧急承载服务启动分组数据网络(Packet Data Network，PDN)连接，则无线通信装置应执行新的附着过程。当无线通信装置接收到该拒绝原因值#10，则无线通信装置所需执行的动作的对应英文可以为：
If the rejected request was not for initiating a PDN connection for emergency bearer services,the UE shall then perform a new attach procedure。
其中，当拒绝原因值为#40，则表示没有演进的分组系统(Evolved Packet System，EPS)承载上下文被激活(No EPS bearer context activated)。当无线通信装置接收到该拒绝原因值#40，则：无线通信装置应在本地停用所有EPS承载上下文(如果有的话)，并进入EMM状态-注销，正常-服务，无线通信装置应执行新的附着过程。当无线通信装置接收到该拒绝原因值#40，则无线通信装置所需执行的动作的对应英文可以为：
The UE shall deactivate all the EPS bearer contexts locally,if any,and shall enter the state EMM-DEREGISTERED.NORMAL-SERVICE.The UE shall perform a new attach procedure。
通过上述步骤S302和步骤S307可以看出，当用户在无线通信装置进行了语音业务，比如发起语音呼叫的操作之后，直至该语音呼叫被被叫方接听前，无线通信装置的显示屏上一直显示的是语音业务对应的语音通话处于待接通状态的信息，直至该语音呼叫在第二小区被接通，则在显示屏上显示语音业务对应的语音通话处于接通状态的信息。
可以看出，即使无线通信装置驻留了伪网络设备(第一网络设备)，在第一小区执行语音业务失败的情况下，无线通信装置不会再显示屏上显示用于指示语音业务失败的信息， 即对于用户而言，并未感受到该语音业务被中断，因此用户也不必在第一小区执行语音业务失败的情况下再次发起语音呼叫，从而可以减少用户的操作次数。
本申请实施例中无线通信装置的相关方法流程可以由无线通信装置中的处理模块来执行，比如步骤S303、步骤S304、步骤S305和步骤S306等等。本申请实施例中的处理模块可以为无线通信装置的协议栈中的模块。关于处理模块的具体说明可以参见后续内容中的实体装置的介绍，在此先不做介绍。
基于上述内容，图3b示例性示出了场景二的一种通信方法的流程示意图，该图3b是在图3a的基础上的提供的一种可能地实施方式。与图3a相比，图3b中的主要的不同点在于：
步骤S304中以拒绝原因值为#9、#10或#40等进行示例。基于该原因值，图3a中的步骤S308可以通过图3b中的步骤S3081、步骤S3082、步骤S3083、步骤S3084和步骤S3085来实现。
步骤S3081，无线通信装置确定语音业务执行失败，无线通信装置在显示屏上显示第三显示信息。
步骤S3082，无线通信装置接收第二网络设备下发的系统消息。
步骤S3083，无线通信装置向第二网络设备发送附着请求消息。
本申请实施例中的附着请求消息可以是attach request。
步骤S3084，第二网络设备接收到附着请求消息之后，向无线通信装置发送附着接受消息。
本申请实施例中的附着接受消息可以是连接建立attach accept。
步骤S3085，无线通信装置向第二网络设备发送附着完成消息。
本申请实施例中的附着完成消息可以是attach complete。
可以看出，无论前述步骤S304中无线通信装置接收到的拒绝原因值具体是什么，比如为前述#9、#10或#40等指示无线通信装置重新附着的原因值，本申请实施例中在确定第一网络设备为伪网络设备时，并不会根据该原因值去执行附着流程，而是接入第二小区再次发起服务请求，以便接续该语音业务。而当第一网络设备并非伪网络设备的情况下，无线通信装置才会根据具体的拒绝原因值去执行相应的流程，比如当拒绝原因值为#9、#10或#40等指示无线通信装置重新附着的原因值，在第一网络设备并非伪网络设备的情况下，通过步骤S3081至步骤S3085执行附着流程。
基于上述图3a和图3b所示的内容，图3c示例性示出了一种无线通信装置与第一网络设备之间进行通信的流程示意图，图3c所示的方法步骤可以为前述步骤S201中的一种可能地实施方式中，如图3c所示，该方法包括：
步骤S401，无线通信装置接收到来自第一网络设备的系统消息。
本申请实施例中，步骤S401中的系统消息可以是system information。比如，可以通过接收广播消息的方式接收系统消息。
本申请实施例中系统消息中可以包括有驻留小区频点、频段、公共陆上移动网(Public Land Mobile Network，PLMN)、物理小区标识(Identification，ID)、带宽、非连续接收(discontinuous Reception，DRX)周期等信息。
通过步骤S401，无线通信装置可以驻留在第一小区。一种可能地实施方式中，在步骤S401之后执行步骤S303。
步骤S303，无线通信装置可以向第一网络设备发送第一消息。第一消息可以为跟踪区更新请求消息或位置区更新请求消息。
一种可能地实施方式中，在步骤S303之后建立RRC链接，具体可以通过如下步骤实现：
步骤S402，无线通信装置向第一网络设备发送无线资源控制(Radio Resource Control，RRC)连接建立请求消息。
本申请实施例中的RRC连接建立请求消息可以是连接建立请求RRC Connection setup request。
RRC连接建立请求消息也可以有其他名称，比如，在一种可能地实施方式中，在LTE下的RRC连接建立请求消息也可以写为LTE RRC connection setup request。其中，LTE为长期演进(Long Term Evolution，LTE)的简称。再比如，在NR下的RRC连接建立请求消息也可以写为NR RRC connection setup request。其中，NR为新无线(New Radio，NR)的简称。
步骤S403，第一网络设备接收到RRC连接建立请求消息之后，向无线通信装置发送RRC连接建立响应消息。
本申请实施例中的RRC连接建立响应消息可以是RRC Connection setup。
RRC连接建立响应消息也可以有其他名称，比如，在一种可能地实施方式中，在LTE下的RRC连接建立响应也可以写为LTE RRC connection setup。再比如，在NR下的RRC连接建立响应消息也可以写为NR RRC connection setup。

一种可能地实施方式中，第一网络设备为伪网络设备的情况下，伪网络设备在RRC连接建立完成后不再触发后续的鉴权操作，而是直接向无线通信装置发送身份识别请求消息(IDENFITY_REQ)，以请求获取无线通信装置的IMSI。这种实施方式中，在步骤S405之后可以包括步骤S406和步骤S407。
步骤S405，第一网络设备向无线通信装置发送身份识别请求消息，以查询国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)。
身份识别请求消息可以为identity request。
步骤S406，无线通信装置向第一网络设备返回身份识别响应消息，该身份识别响应消息中可以携带无线通信装置的IMSI。
身份识别响应消息可以为identity response。
步骤S304，第一网络设备下发第二消息。
一种可能地实施方式中，当伪网络设备在查询到无线通信装置的IMSI后，即向无线通信装置发送第二消息。第二消息可以为跟踪区更新拒绝消息或位置区更新拒绝消息。
第二消息中可以携带前述的拒绝原因值。
步骤S407，第一网络设备向无线通信装置发送RRC连接释放消息，以释放与终端设备间的RRC连接。
本申请实施例中的RRC连接释放消息可以为rrc_connection_release，也可以写为RRC_CONN_RELEASE。
通过上述图3c所示的方案可以看出，无线通信装置在第一网络设备发起语音业务的情况下，由于无线通信装置与第一网络设备之间的RRC链接被释放，因此无法成功在第一小区发起语音业务，也可以理解为在第一小区执行语音业务失败。
基于上述图3a、图3b和图3c所示的内容，图3d示例性示出了一种无线通信装置与第二网络设备之间进行通信的流程示意图，图3d所示的方法步骤可以为前述步骤S306中的一种可能地实施方式中，如图3d所示，该方法包括：
步骤S3061，无线通信装置接收第二网络设备发送的系统消息。
本申请实施例中，步骤S3061中的系统消息可以参见前述步骤S401中的系统消息的相关描述，在此不再赘述。
步骤S3062，无线通信装置向第二网络设备发送第三消息。
步骤S3062中第三消息可以为跟踪区更新请求消息、位置区更新请求消息或服务请求消息。
本申请实施例中，跟踪区更新请求消息可以为track area update request，也可以写为TAU_REQ。位置区更新请求消息可以为location area update request，也可以写为LAU_REQ。服务请求消息可以为server request，也可以写为SER_REQ。
当第三消息为服务请求消息，则步骤S3062中的服务请求可以用于请求执行语音业务。
步骤S3063，无线通信装置向第二网络设备发送无线资源控制(Radio Resource Control，RRC)连接建立请求消息。
本申请实施例中的RRC连接建立请求消息可以是RRC setup request。
步骤S3064，第二网络设备接收到RRC连接建立请求消息之后，向无线通信装置发送RRC连接建立响应消息。
本申请实施例中的RRC连接建立响应消息可以是连接建立RRC setup。

本申请实施例中的RRC连接建立完成消息可以是RRC connection setup complete。
步骤S3066，第二网络设备向无线通信装置发送第四消息。
步骤S3066中第四消息可以为跟踪区更新接受消息、位置区更新接受消息或服务接受消息。
本申请实施例中，跟踪区更新接受消息可以为track area update accept。位置区更新接受消息可以为location area update accept。服务接受消息可以为server accept。
步骤S3067，无线通信装置向第二网络设备发送第五消息。
步骤S3067中第五消息可以为跟踪区更新完成消息或位置区更新完成消息。
本申请实施例中，跟踪区更新完成消息可以为track area update complete。位置区更新完成消息可以为location area update complete。
可以理解，本申请实施例中第三消息、第四消息和第五消息之间可以有一种对应关系，比如当第三消息为跟踪区更新请求消息，则对应的第四消息可以为跟踪区更新接受消息， 第五消息可以为跟踪区更新完成消息。再比如，当第三消息为位置区更新请求消息，则对应的第四消息可以为位置区更新接受消息，第五消息可以为位置区更新完成消息。再比如，当第三消息为服务新请求消息，则对应的第四消息可以为服务接受消息，这种情况下也可以没有第五消息。
步骤S3068，无线通信装置在第二小区发送会话邀请消息。
在步骤S3068中，无线通信装置可以向第二网络设备发送会话邀请消息。
本申请实施例中的会话邀请消息可以是invite，比如IMS_SIP_OUTGOING(sip_invite)。会话邀请消息可以用于发起语音业务。
本申请实施例中当第二网络设备为5G的网络制式时，该语音业务可以为新无线语音方案(voice on New Radio，VoNR)服务。当第二网络设备为5G的网络制式时，该语音方案也可以为演进分组系统回落方案(Evolved Packet System，EPSFB)服务。当第二网络设备为4G的网络制式时，该语音业务可以为长期演进语音方案(voice on long term evolution，VoLTE)服务。当第二网络设备为2G或3G的网络制式时，该语音业务可以为电路域(Circuit Switchedk，CS)的语音服务。
步骤S3069，无线通信装置接收到第二网络设备返回的会话邀请消息响应。
本申请实施例中，会话邀请消息响应可以为100trying。
步骤S30610，第二网络设备向无线通信装置发送承载建立请求。
本申请实施例中，步骤S3068中的承载建立请求可以为activate dedicated eps bearer context request。
步骤S30611，无线通信装置向第二网络设备发送承载建立接受。

步骤S30611，无线通信装置与第二网络设备等进行媒体协商。
通过步骤S30611可以协商该语音业务的一些信息，比如可以协商该语音通话过程中所传输的数据的编码形式等信息。
步骤S30613，第二网络设备向无线通信装置下发响铃消息。
响铃消息可以为180Ringing。
当下发响铃消息后，无线通信装置作为主叫方，无线通信装置的用户可以听到嘟嘟声，该嘟嘟声可以表示被叫方的无线通信装置已经显示来电，等等被叫方接听。
步骤S30614，待被叫方用户接听该语音业务对应的语音呼叫后，无线通信装置的用户可以与被叫方进行语音通话。
下述步骤S30615至步骤S30619描述了一种可能地的呼叫挂断的过程的示例。该语音通话可以由主叫方挂断，也可以由被叫方挂断，下面以主叫方挂断为例进行展示：
步骤S30615，无线通信装置接收到用户(主叫方)挂断电话的操作，基于该操作，向第二网络设备发送呼叫挂断消息。
在上述示例中可以看出，本申请实施例中，呼叫挂断消息用于指示语音业务的结束。
S30615呼叫挂断消息也可以是bye消息。

步骤S30619，第二网络设备向无线通信装置发送RRC连接释放消息。
RRC连接释放消息也可以称为RRC connection release。
可以看出，无论前述步骤S304中第二消息携带的拒绝原因值具体是什么，比如为前述#9、#10等，本申请实施例中在确定第一网络设备为伪网络设备时，并不会根据该原因值去执行附着流程，而是通过执行跟踪区更新、位置区更新后，接入第二小区再次发起服务请求，以便接续该语音业务。
通过上述图3a至图3d描述了场景一的方案，需要说明的是，在场景一中，第一网络设备和第二网络设备可以属于不同的网络制式。比如第一网络设备可以为4G的网络制式，而第二网络设备可以为4G的网络制式，也可以为其他比如3G或2G的网络制式，这种情况下，当无线通信装置在4G制式的第一网络设备下发起语音业务，后续可以回落至2G或3G进行语音业务。又一种可能的实施方式中，比如，第一网络设备可以为5G的网络制式，而第二网络设备可以为5G的网络制式，也可以为其他比如4G的网络制式，这种情况下，当无线通信装置在5G制式的第一网络设备下发起语音业务，后续可以回落至4G进行语音业务。
进一步，一种可能地实施方式中，可能在第二小区由于某些原因语音业务也会呼叫失败，这种情况下也可以继续执行伪网络设备的识别策略，当识别出第二小区所属的网络设备也为伪网络设备的情况下，也可以继续切换至其他小区，比如第四小区再次进行语音通话业务。本申请实施例对于无线通信装置驻留了几个伪网络设备的小区可以不做限定。本申请实施例中提供的方案中，当无线通信装置进行语音通话失败后，则可以执行伪网络设备的识别策略，继而结合识别结果确定无线通信装置上显示的信息，以及后续的操作。相关操作可以参见第一小区和第二小区的介绍，不再赘述。
通过上述图3a至图3d提供的方案可以看出，上述场景一中，当用户在伪网络设备发起语音通话的操作，虽然在伪网络设备上执行语音业务失败，但是并不会在无线通信装置的显示屏上显示语音通话失败的信息，而是当用户发起语音通话的操作之后，无线通信装置的显示屏上一直显示的是语音业务对应的语音通话处于待接通状态的信息，直至该语音通话在第二小区被接通，则在显示屏上显示语音业务对应的语音通话处于接通状态的信息。或者，当用户发起语音通话的操作之后，无线通信装置的显示屏上一直显示的是语音业务对应的语音通话处于待接通状态的信息，直至该语音通话在第二小区被拒接，则在显示屏上显示语音业务对应的语音通话处于未接通状态的信息。即对于用户而言，并未感受到由于驻留伪网络设备而导致语音业务被中断，因此用户也不必在第一小区执行语音业务失败的情况下再次发起语音通话，从而可以减少用户的操作次数。
场景二，无线通信装置在除第一小区之外的小区，比如第三小区发起语音业务，在语音业务的进行过程中切换至第一小区。
第三小区为第三网络设备下的一个小区。其中，第三网络设备与第一网络设备为两个不同的网络设备。第三网络设备与第二网络设备可以为同一个网络设备，也可以为不同的网络设备。第三小区与第二小区可以为同一个小区，也可以为不同的小区。
基于上述内容，图4a示例性示出了场景二的一种通信方法的流程示意图，如图4a所 示，该方法包括：
步骤S501，无线通信装置在第三小区进行语音业务。无线通信装置的显示屏上显示第二显示信息，第二显示信息用于指示语音业务对应的语音通话处于接通状态。
在步骤S501中，无线通信装置可以为主叫方，也可以为被叫方。关于无线通信装置与第三网络设备之间的通信流程，后续内容再进行详细描述，在此先不做介绍。
步骤S502，无线通信装置驻留第一小区，且在第一小区进行语音业务失败。
步骤S502可以理解为上述步骤S201的一种可能地实施方式。
一种可能地实施方式中，无线通信装置可以接收来自第一网络设备的第一指示信息，第一指示信息可以为拒绝原因值，比如为前述内容中提到的#13、#15、#9、#10或#40等等。
步骤S503，无线通信装置执行伪网络设备识别策略，识别第一小区所属的第一网络设备是否为伪网络设备；
若是，则可以执行步骤S504；若否，则可以执行步骤S505；
步骤S504，无线通信装置接入第二小区，在第二小区进行语音业务。
识别伪网络设备的策略可以参见前述内容，在此不再赘述。
步骤S504中，当在第二小区成功接续该语音业务后，用户可以继续通过无线通信装置与对方进行语音通话。从无线通信装置在第一小区进行语音业务后，在显示屏上显示第二显示信息开始，直至步骤S504之前，无线通信装置一直在显示屏上显示第二显示信息。当在步骤S504中，成功在第二小区进行语音业务，即在第二小区成功接续该语音业务后，无线通信装置的显示屏上仍然显示第二显示信息。又一种可能地实施方式中，当在第二小区成功进行语音业务，后续语音业务被其中一个用户挂断，这种情况下，无线通信装置可以将显示屏上的信息从第二显示信息更新为第四显示信息，第四显示信息显示用户挂断该语音通话后的界面。
一种可能地实施方式中，当接收到第二消息，无线通信装置的显示屏显示第二显示信息而并不是第三显示信息，第二显示信息用于指示语音业务对应的语音通话处于接通状态。
又一种可能地实施方式中，第一网络设备为伪网络设备的情况下，无线通信装置的显示屏在第二时间段内显示的信息为第二显示信息，第二显示信息用于指示语音业务对应的语音通话处于接通状态。其中，第二时间段的起始点为：在第三小区发起的语音业务对应的语音通话处于接通状态的时间点。第二时间段的终止点：晚于发送第一RRC重配置请求消息的时间。也就是说，在整个第二时间段内，无线通信装置均显示第二显示信息，即使在第一时间段内，无线通信装置驻留了伪网络设备，无线通信装置也不会再第二时间段显示语音业务结束(或者说失败、中断等)的相关信息。
步骤S505，无线通信装置确定语音业务执行失败，无线通信装置在显示屏上显示第三显示信息。
一种可能地实施方式中，步骤S505中的方案也可以为：当无线通信装置确定语音业务执行失败后，无线通信装置将显示屏上显示的信息从第二显示信息更新为第三显示信息。
步骤S308中，一种可能地实施方式中，当无线通信装置接收到的来自第一网络设备的拒绝原因值时，可以根据拒绝原因值执行相应的动作。可以参见前述步骤S308。
通过上述方案可以看出，当用户在其他小区执行语音业务，在语音业务进程中驻留了伪网络设备，则当无线通信装置切换至第三网络设备后，可以接续该语音业务。该过程中， 从用户开始执行语音业务开始，无线通信装置的显示屏上即显示第二显示信息，即使无线通信装置驻留了伪网络设备导致了语音业务的执行失败，然而当第一网络设备为伪网络设备的情况下，无线通信装置也并未在显示屏上显示用于指示语音业务失败的信息，而是继续显示用于指示语音业务对应的语音通话处于接通状态的信息，直至在第二小区成功接续该语音业务。对于用户而言，用户并未看到无线通信装置的显示屏上的语音业务失败的信息，因此并不会感知无线通信装置因为驻留伪基站而导致的语音业务失败的情况，因此用户也不必在第一小区执行语音业务失败的情况下再次发起语音通话，从而可以减少用户的操作次数。
基于上述内容，图4b示例性示出了场景二的一种通信方法的流程示意图，该图4b是在图4a的基础上的提供的一种可能地实施方式。与图4a相比，图4b中的主要的不同点在于：
步骤S502中以拒绝原因值为#9、#10或#40等进行示例。基于该原因值，图4a中的步骤S505可以通过图4b中的步骤S5051、步骤S5052、步骤S5053、步骤S5054和步骤S5055来实现。
步骤S5051，无线通信装置确定语音业务执行失败，无线通信装置在显示屏上显示第三显示信息。
步骤S5052，无线通信装置接收第二网络设备下发的系统消息。
步骤S5053，无线通信装置向第二网络设备发送附着请求消息。
本申请实施例中的附着请求消息可以是attach request。
步骤S5054，第二网络设备接收到附着请求消息之后，向无线通信装置发送附着接受消息。
本申请实施例中的附着接受消息可以是连接建立attach accept。
步骤S5055，无线通信装置向第二网络设备发送附着完成消息。
本申请实施例中的附着完成消息可以是attach complete。
可以看出，无论前述步骤S502中无线通信装置接收到的拒绝原因值具体是什么，比如为前述#9、#10或#40等指示无线通信装置重新附着的原因值，本申请实施例中在确定第一网络设备为伪网络设备时，并不会根据该原因值去执行附着流程，而是接入第二小区再次发起服务请求，以便接续该语音业务。而当第一网络设备并非伪网络设备的情况下，无线通信装置才会根据具体的拒绝原因值去执行相应的流程，比如当拒绝原因值为#9、#10或#40等指示无线通信装置重新附着的原因值，在第一网络设备并非伪网络设备的情况下，通过步骤S5051至步骤S5055执行附着流程。
在场景二中，无线通信装置的用户可以作为主叫也可以作为被叫。下面图5a和图5b介绍了场景二中无线通信装置的用户作为主叫方的一种通信方法流程示意图，图6a和图6b介绍了场景二中无线通信装置的用户作为被叫方的一种通信方法流程示意图。下面结合附图分别进行介绍。

步骤S703，无线通信装置驻留在第三小区。无线通信装置基于第一操作信息的触发，向被叫方拨打语音通话，待语音通话被被叫方接通后，无线通信装置在第三小区进行语音业务。

在步骤S7036，无线通信装置接收到第三网络设备返回的会话邀请消息响应。
本申请实施例中，会话邀请消息响应可以为100trying。

基于上述图4a至图6b所示的内容，图7示例性示出了一种无线通信装置与第一网络设备之间进行通信的流程示意图，图7所示的方法步骤可以为前述步骤S502中的一种可能地实施方式中，如图7所示，该方法包括：
步骤S5021，无线通信装置接收到来自第一网络设备的系统消息。
本申请实施例中，系统消息可以参见步骤S401，不再赘述。
通过步骤S5021，无线通信装置可以驻留在第一小区。
步骤S5022，无线通信装置可以向第一网络设备发送第一消息。
第一消息可以为跟踪区更新请求消息或位置区更新请求消息。
步骤S5023，无线通信装置向第一网络设备发送无线资源控制(Radio Resource Control，RRC)连接建立请求消息。
本申请实施例中的RRC连接建立请求消息可以是连接建立请求RRC Connection setup request。
步骤S5024，第一网络设备接收到RRC连接建立请求之消息后，向无线通信装置发送RRC连接建立响应消息。
本申请实施例中的RRC连接建立响应消息可以是连接建立RRC Connection setup。
步骤S5025，无线通信装置向第一网络设备发送RRC连接建立完成消息。
本申请实施例中的RRC连接建立完成消息可以是RRC Connection setup complete。
一种可能地实施方式中，第一网络设备为伪网络设备的情况下，伪网络设备在RRC连接建立完成后不再触发后续的鉴权操作，而是直接向无线通信装置发送身份识别请求消息(IDENFITY_REQ)，以请求获取无线通信装置的IMSI。这种实施方式中，在步骤S405之后可以包括步骤S5026和步骤S5027。
步骤S5026，第一网络设备向无线通信装置发送身份识别请求消息，以查询IMSI。
身份识别请求消息可以为identity request。
步骤S5027，无线通信装置向第一网络设备返回身份识别响应消息，该身份识别响应消息中可以携带无线通信装置的IMSI。
身份识别响应消息可以为identity response。
步骤S5028，第一网络设备下发第二消息。
一种可能地实施方式中，当伪网络设备在查询到无线通信装置的IMSI后，即向无线通信装置发送第二消息。
第二消息可以为跟踪区更新拒绝消息或位置区更新拒绝消息。
在一种可能地实施方式中，可以在第二消息中携带拒绝原因值。拒绝原因值可以为多种可能，比如拒绝原因值可以为：#9、#10或#40等等。如前，当拒绝原因值为#9、#10或#40等，用于指示无线通信装置重新执行附着流程。
步骤S5029，第一网络设备向无线通信装置发送RRC连接释放消息，以释放与终端设备间的RRC连接。
本申请实施例中的RRC连接释放消息可以为rrc_connection_release，也可以写为RRC_CONN_RELEASE。
通过上述图7所示的方案可以看出，无线通信装置在第三小区进行语音业务，驻留至第一小区后，由于无线通信装置与第一网络设备之间的RRC链接被释放，因此无法成功在第一小区成功继续执行该语音业务，即无法成功在第一小区接续该语音业务，也可以理解为在第一小区执行语音业务失败。继而在第一网络设备为伪网络设备的情况下，在第二小区继续执行该语音业务。
基于上述图4a至图7所示的内容，图8示例性示出了一种无线通信装置与第二网络设备之间进行通信的流程示意图，图8所示的方法步骤可以为前述步骤S504中的一种可能地实施方式中，如图8所示，该方法包括：
步骤S5041，无线通信装置接收第二网络设备发送的系统消息。
本申请实施例中，步骤S323中的系统消息可以参见前述步骤S401中的系统消息的相关描述，在此不再赘述。
步骤S5042，无线通信装置向第二网络设备发送第三消息。
步骤S5042中第三消息可以为跟踪区更新请求消息、位置区更新请求消息或服务请求消息。
本申请实施例中，跟踪区更新请求消息可以为track area update request，也可以写为TAU_REQ。位置区更新请求消息可以为location area update request，也可以写为LAU_REQ。服务请求消息可以为server request，也可以写为SER_REQ。
当第三消息为服务请求消息，则步骤S5042中的服务请求可以用于请求执行语音业务。

本申请实施例中的RRC连接建立完成消息可以是RRC setup complete。
步骤S5046，第二网络设备向无线通信装置发送第四消息。
步骤S5046中第四消息可以为跟踪区更新接受消息、位置区更新接受消息或服务接受消息。
本申请实施例中，跟踪区更新接受消息可以为track area update accept。位置区更新接受消息可以为location area update accept。服务接受消息可以为server accept。
步骤S5047，无线通信装置向第二网络设备发送第五消息。
步骤S5047中第五消息可以为跟踪区更新完成消息或位置区更新完成消息。
本申请实施例中，跟踪区更新完成消息可以为track area update complete。位置区更新完成消息可以为location area update complete。
可以理解，本申请实施例中第三消息、第四消息和第五消息之间可以有一种对应关系，比如当第三消息为跟踪区更新请求消息，则对应的第四消息可以为跟踪区更新接受消息，第五消息可以为跟踪区更新完成消息。再比如，当第三消息为位置区更新请求消息，则对应的第四消息可以为位置区更新接受消息，第五消息可以为位置区更新完成消息。再比如，当第三消息为服务新请求消息，则对应的第四消息可以为服务接受消息，这种情况下也可以没有第五消息。
步骤S5048，第二网络设备向无线通信装置发送第一RRC重配置请求消息。
步骤S5048中的第一RRC重配置请求消息可以用于请求为该语音业务配置数据资源承载(Data Radio Bearer，DRB)。
本申请实施中的RRC重配置消息(比如为第一RRC重配置消息以及后续提及的第二RRC重配置消息)可以为RRC Connection Reconfiguration，可以写为RRC_Conn_Recfg。
步骤S5049，无线通信装置向第二网络设备发送第一RRC重配置完成消息。
在通过步骤S5048和步骤S5049之后，为该语音业务重新配置DRB，进而可以执行步骤S50410。
本申请实施中的RRC重配置完成消息(比如为第一RRC重配置完成消息以及后续提及的第二RRC重配置完成消息)可以为RRC Connection Reconfiguration Complete，可以写为RRC_Conn_Recfg_Cmp。
步骤S50410，无线通信装置的用户(主叫方)与被叫方继续进行语音通话。
下述步骤S50411至步骤S50417描述了一种可能地的呼叫挂断的过程的示例。该语音通话可以由主叫方挂断，也可以由被叫方挂断，下面以主叫方挂断为例进行展示：
步骤S50411，无线通信装置接收到用户(主叫方)挂断电话的操作，基于该操作，向 第二网络设备发送呼叫挂断消息。
在上述示例中可以看出，本申请实施例中，呼叫挂断消息用于指示语音业务的结束。
S50411呼叫挂断消息也可以是bye消息。
步骤S50412，第二网络设备向无线通信装置发送200OK消息。
步骤S50413，第二网络设备向无线通信装置发送第二RRC重配置请求消息。
步骤S50413中的第二RRC重配置请求消息可以用于请求将该语音业务配置的DRB删除。
步骤S50414，无线通信装置向第二网络设备发送第二RRC重配置完成消息。
第二RRC重配置完成消息可以用于指示为该语音业务配置的DRB删除完成。
步骤S50415，第二网络设备向无线通信装置发送承载去激活请求。
承载去激活请求可以用于请求对基于该语音业务建立的承载进行去激活。
步骤S50416，无线通信装置向第二网络设备发送承载去激活完成。
承载去激活完成可以用于指示基于该语音业务建立的承载已经去激活。
步骤S50417，第二网络设备向无线通信装置发送RRC连接释放消息。
RRC连接释放消息也可以称为RRC release。
可以看出，无论前述步骤S305中第二消息携带的拒绝原因值具体是什么，比如为前述#9、#10或#40等，本申请实施例中在确定第一网络设备为伪网络设备时，并不会根据该原因值去执行附着流程，而是通过执行跟踪区更新、位置区更新后，接入第二小区再次发起服务请求，以便接续该语音业务。
通过上述图4a至图8描述了场景二的方案，需要说明的是，在场景二中，第一网络设备、第二网络设备和第三网络设备中任两个网络设备均可以属于不同的网络制式。比如第三网络设备可以为5G网络制式，第一网络设备可以为4G的网络制式，而第二网络设备可以为3G或2G的网络制式，这种情况下，当无线通信装置在5G制式的第三网络设备下发起语音业务，后续可以回落至4G、或者2G、3G等进行语音业务。当然，第一网络设备、第二网络设备和第三网络设备中两个网络设备也可以属于相同的网络制式，本申请实施例不做限定。
进一步，一种可能地实施方式中，可能在第二小区由于某些原因语音业务也会呼叫失败，这种情况下也可以继续执行伪网络设备的识别策略，当识别出第二小区所属的网络设备也为伪网络设备的情况下，也可以继续切换至其他小区，比如第四小区再次进行语音通话业务。本申请实施例对于无线通信装置驻留了几个伪网络设备的小区可以不做限定。本申请实施例中提供的方案中，当无线通信装置进行语音通话失败后，则可以执行伪网络设备的识别策略，继而结合识别结果确定无线通信装置上显示的信息，以及后续的操作。相关操作可以参见第一小区和第二小区的介绍，不再赘述。
通过上述图4a至图8提供的方案可以看出，上述场景二中，当用户合法的网络设备发起语音通话，并进行语音业务，在执行语音业务的进程中驻留至伪网络设备，虽然在伪网络设备上执行语音业务失败，但是并不会在无线通信装置的显示屏上显示语音通话失败的信息，而是当用户在合法的网络设备下执行该语音业务(接通该语音通话后)，无线通信装置的显示屏上一直显示的是语音业务对应的语音通话处于接通状态的信息，即使在语音通话的进程中驻留至伪网络设备导致与网络设备之间的RRC链接被释放，无线通信装置的显示屏上依然显示接通状态，仅仅是当驻留至伪网络设备时无法有效的传输双方用户的 声音信号，当无线通信装置驻留至合法网络设备，则可以有效传输双方用户的声音信号。这整个过程，对于用户而言，并未感受到由于驻留伪网络设备而导致语音业务被中断，因此用户也不必在第一小区执行语音业务失败的情况下再次发起语音通话，从而可以减少用户的操作次数。
基于上述内容，图9和图10示例性介绍了无线通信装置的界面示意图，其中，图9中无线通信装置作为主叫方，图10中无线通信装置作为被叫方。图9和图10中均是无线通信装置为手机为例进行示意，本申请实施例中的无线通信装置也可以为其他具有语音通话功能的装置。下面结合图9和图10进行介绍。
如图9所示，图9中的(a)为手机的主界面，用户可以点击电话功能，则手机的界面如图9中的(b)所示。用户可以在图9中的(b)中的联系人的标签中选择被叫方，比如选择丽丽作为被叫方，用户可以执行“点击界面上丽丽”的操作，该操作可以为上述图2至图6b中涉及到的步骤S301中的操作，也可以为上述步骤S701中的操作。
响应于用户在图9中的(b)上执行的操作，手机界面如图9中的(c)所示，图9中的(c)显示的为向丽丽发起了语音通话，响应于该操作，手机界面上显示第一子显示信息，第一子显示信息用于指示用户作为主叫方已经发起了语音通话，但是该无线通信装置还未发送响铃消息(比如前述步骤S30613和步骤S70310中的响铃消息)，因此被叫方的无线通信装置还未显示来电信息，也可以说被叫方的无线通信装置还未震动，或者还未响铃。为了介绍方便，被叫方的无线通信装置还未显示来电信息的状态称为：被叫方还未振铃。如图9中的(c)所示，主叫方的无线通信装置的界面会显示的第一子显示信息可以为：正在拨号…。
一种可能地实施方式中，当该无线通信装置发送响铃消息(比如前述步骤S30613和步骤S70310)，则该作为主叫方的无线通信装置的显示屏上可以显示第二子显示信息。第二子显示信息用于指示被叫方的无线通信装置已显示来电信息，也可以说被叫方的无线通信装置已震动，或者已响铃。为了介绍方便，被叫方的无线通信装置已显示来电信息的状态称为：被叫方已振铃。如图9中的(d)所示，主叫方的无线通信装置的界面会显示的第一子显示信息可以为：对方已振铃。该阶段但是该语音通话还未被丽丽接听。一种可能地实施方式中，可以从手机中传出“嘟嘟”的响铃声。
可以理解为图9中的(d)中手机界面显示第一显示信息，第一显示信息用于指示语音业务对应的语音通话处于待接通状态。
当该语音业务被丽丽接听，主叫方和被叫方处于通话状态，则手机界面可以如图9中的(e)所示。可以理解为图9中的(e)中手机界面显示第二显示信息，第二显示信息用于指示语音业务对应的语音通话处于接通状态。用户可以在该状态下与被叫方进行语音通话。
当语音通话结束，可以由主叫方结束通话，也可以由被叫方结束通话。图9中是以主叫方结束通话进行示意的，比如图9中的(e)所示，用户可以在该手机界面上执行“点击挂断按钮”的操作，该操作可以触发上述图2至图6b中涉及到的步骤S30717或步骤S50412中的操作。用户执行“点击挂断按钮”的操作后，手机的界面回到主界面，如图9中的(f)所示。这种情况下，也可以理解为当用户挂断电话后，手机的界面上显示第四显示信息，该第四显示信息用于指示语音通话处于挂断状态。
需要说明的是，上述第一子显示信息和第二子显示信息中的任一项均可以属于本申请实施例提到的第一显示信息。第一显示信息用于指示语音通话处于待接通状态，可以包括正在拨号阶段(图9中的(c)所示的界面)(对方未振铃阶段)，以及对方已振铃(图9中的(d)所示的界面)阶段。
从图9中可以看出，当用户执行用于发起语音通话的第一操作后，在发送响铃消息之前，无线通信装置均显示第一子显示信息。当发送响铃消息之后，无线通信装置显示第二子显示信息。
结合上述图3a至图3d进行说明，一种可能地实施方式中，当上述步骤S301之后，手机的界面图如图9中的(c)所示，且持续显示第一显示信息中的第一子显示信息，当第一网络设备为伪网络设备，且无线通信装置接入第二小区，并接通与被叫方的语音通话后，即在上述步骤S306之后，直至步骤S30613为止，无线通信装置均持续显示第一子显示信息。在步骤S30613之后，无线通信装置显示第一显示信息中的第二子显示信息，手机的界面从图9中的(c)更新为图9中的(d)。无线通信装置显示第一显示信息直至被叫方接听该语音通话。当被叫方接听该语音通话后，手机的界面从图9中的(d)更新为图9中的(e)。可以看出，在手机界面从图9中的(c)更新至图9中的(e)的过程中，虽然该过程中无线通信装置驻留至伪网络设备，但是用户并未感知到因为驻留伪网络设备而导致语音业务失败的事件，因此对于用户而言，并不需要再次发起语音业务，从而可以减少用户的操作。
结合上述图5a和图5b进行说明，当上述步骤S701之后，手机的界面可以如图9中的(c)所示，显示第一显示信息中的第一子显示信息，直至上述图5b中的步骤S70310中的响铃消息为止。当执行上述图5b中的步骤S70310中的响铃消息后，手机的界面可以如图9中的(d)所示，显示第一显示信息中的第二子显示信息。当该语音通话被被叫方接听后，可以如图9中的(e)所示，显示第二显示信息。
进一步，结合上述图4a进行说明，当上述步骤S501之后，手机的界面图如图9中的(e)所示，且持续显示第二显示信息，当第一网络设备为伪网络设备，且无线通信装置接入第二小区，并接通与被叫方的语音通话后，即在上述步骤S504后，手机的界面始终维持图9中的(e)的界面，而用户可以在上述步骤S504后恢复与被叫方的通话。可以看出，虽然无线通信装置在语音通话开启后驻留至伪网络设备，但是用户在语音通话开启后，始终看到的是语音通话处于接通状态的界面，即始终是图9中的(e)所示的界面，因此并未感知到因为驻留伪网络设备而导致语音业务失败的事件，因此对于用户而言，并不需要再次发起语音业务，从而可以减少用户的操作。
如图10所示，图10中的(a)为手机作为被叫方，接收到主叫方的语音通话时的主界面，这种情况下，可以理解为手机显示屏上显示第一显示信息。一种可能地实施方式中，第一显示信息可以包括第三子显示信息。第三子显示信息用于指示无线通信装置作为被叫方，接收到主叫方的语音呼叫时的界面所显示的信息。第三子显示信息用于指示该语音通话处于待接通状态。用户可以执行“点击接受按钮”的操作，以便接听该语音通话。比如图10中的(b)所示，用户手指电机接受按钮，则手机的界面如图10中的(c)所示，显示第二显示信息，即该语音通话处于接通状态，这种情况下，主叫方可以和被叫方进行语音通话。当语音通话结束，可以由主叫方结束通话，也可以由被叫方结束通话。图10中 是以被叫方结束通话进行示意的，比如图10中的(d)所示，用户可以在该手机界面上执行“点击挂断按钮”的操作，该操作可以触发上述图2至图6b中涉及到的步骤S30717或步骤S50412中的操作。用户执行“点击挂断按钮”的操作后，手机的界面回到主界面，如图10中的(e)所示。这种情况下，也可以理解为当用户挂断电话后，手机的界面上显示第四显示信息，该第四显示信息用于指示语音通话处于挂断状态。
结合上述图6a和图6b进行说明，当上述步骤S802中的步骤S80210之后，手机的界面可以如图10中的(a)所示，显示第一显示信息中的第三子显示信息。当用户接听该语音通话后，即执行步骤S803的操作后，手机界面可以如图10中的(c)所示。
进一步，结合上述图4a进行说明，当上述步骤S501之后，手机的界面图如图10中的(c)所示，且持续显示第二显示信息，当第一网络设备为伪网络设备，且无线通信装置接入第二小区，并接通与被叫方的语音通话后，即在上述步骤S504后，手机的界面始终维持图10中的(c)的界面，而用户可以在上述步骤S504后恢复与被叫方的通话。可以看出，虽然无线通信装置在语音通话开启后驻留至伪网络设备，但是用户在语音通话开启后，始终看到的是语音通话处于接通状态的界面，即始终是图10中的(c)所示的界面，因此并未感知到因为驻留伪网络设备而导致语音业务失败的事件，因此对于用户而言，并不需要再次发起语音业务，从而可以减少用户的操作。
需要说明的是，前述图2至图8提到了，当第一网络设备并非伪网络设备，则无论无线通信装置为主叫方还是作为被叫方，则均确定语音业务执行失败，并在显示屏上显示第三显示信息，第三显示信息用于指示语音业务对应的语音通话处于结束状态。当显示屏上显示第三显示信息时，无线通信装置的显示屏的界面示意图可以显示主界面，比如上述图9中的(e)所示的界面，或者为上述图10中的(d)所示的界面。这种情况下，对于用户而言，用户可以看到该语音通话未被打通，或者感受到该语音通话被迫中断，用户可能会再次发起语音通话。
以及，除非有特别说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一跟踪区和第二跟踪区，只是为了区分不同的跟踪区，而并不是表示这两个小区的优先级或者重要程度等的不同。
需要说明的是，上述各个消息的名称仅仅是作为示例，随着通信技术的演变，上述任意消息均可能改变其名称，但不管其名称如何发生变化，只要其含义与本申请上述消息的含义相同，则均落入本申请的保护范围之内。
上述主要从各个网元之间交互的角度对本申请提供的方案进行了介绍。可以理解的是，上述实现各网元为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
根据前述方法，图11a为本申请实施例提供的通信装置的结构示意图，如图11a所示，该通信装置可以为无线通信装置或网络设备(本申请的网络设备比如为前述的第一网络设备、第二网络设备或第三网络设备)，也可以为芯片或电路，比如可设置于无线通信装置 的芯片或电路，再比如可设置于网络设备内的芯片或电路。无线通信装置可以为前述内容中提到的终端设备，或者为终端设备内的芯片或电路。
如图11a所示，该无线通信设备可包括多个组件，例如：应用子系统，内存(memory)，大容量存储器(massive storage)，基带子系统，射频集成电路(radio frequency integrated circuit，RFIC)，射频前端(radio frequency front end，RFFE)器件，以及天线(antenna，ANT)。这些组件可以通过各种互联总线或其他电连接方式耦合。
图11a中，ANT_1表示第一天线，ANT_N表示第N天线，N为大于1的正整数。Tx表示发送路径，Rx表示接收路径，不同的数字表示不同的路径。每条路径均可以表示一个信号处理通道。其中，FBRx表示反馈接收路径，PRx表示主接收路径，DRx表示分集接收路径。HB表示高频，LB表示低频，两者是指频率的相对高低。BB表示基带。应理解，图11a中的标记和组件仅为示意目的，仅作为一种可能的实现方式，本申请实施例还包括其他的实现方式。例如，无线通信设备可以包括更多或更少的路径，包括更多或更少的组件。
其中，应用子系统可包括一个或多个处理器。多个处理器可以多个相同类型的处理器，也可以包括多种类型的处理器组合。本申请中，处理器可以是通用用途的处理器，也可以是为特定领域设计的处理器。例如，处理器可以是中央处理单元(center processing unit，CPU)，数字信号处理器(digital signal processor，DSP)，或微控制器(micro control unit，MCU)。处理器也可以是图形处理器(graphics processing unit，GPU)、图像信号处理器(image signal processing，ISP)，音频信号处理器(audio signal processor，ASP)，以及为人工智能(artificial intelligence，AI)应用专门设计的AI处理器。AI处理器包括但不限于神经网络处理器(neural network processing unit，NPU)，张量处理器(tensor processing unit，TPU)以及被称为AI引擎的处理器。
射频集成电路(包括RFIC 1，以及一个或多个可选的RFIC 2)和射频前端器件可以共同组成射频子系统。根据信号的接收或发送路径的不同，射频子系统也可以分为射频接收通道(RF receive path)和射频发射通道(RF transmit path)。其中，射频接收通道可通过天线接收射频信号，对该射频信号进行处理(如放大、滤波和下变频)以得到基带信号，并传递给基带子系统。射频发送通道可接收来自基带子系统的基带信号，对基带信号进行处理(如上变频、放大和滤波)以得到射频信号，并最终通过天线将该射频信号辐射到空间中。射频集成电路可以被称为射频处理芯片或射频芯片。
与射频子系统主要完成射频信号处理类似，基带子系统主要完成对基带信号的处理。基带子系统可以从基带信号中提取有用的信息或数据比特，或者将信息或数据比特转换为待发送的基带信号。这些信息或数据比特可以是表示语音、文本、视频等用户数据或控制信息的数据。例如，基带子系统可以实现诸如调制和解调，编码和解码等信号处理操作。对于不同的无线接入技术，例如5G NR和4G LTE，基带信号处理操作也不完全相同。
与应用子系统类似，基带子系统也可包括一个或多个处理器。此外，基带子系统还可以包括一种或多种硬件加速器(hardware accelerator，HAC)。硬件加速器可用于专门完成一些处理开销较大的子功能，如数据包(data packet)的组装和解析，数据包的加解密等。这些子功能采用通用功能的处理器也可以实现，但是因为性能或成本的考量，采用硬件加速器可能更加合适。在具体的实现中，硬件加速器主要是用专用集成电路(application specified integrated circuit，ASIC)来实现。当然，硬件加速器中也可以包括一个或多个相 对简单的处理器，如MCU。
基带子系统可以集成为一个或多个芯片，该芯片可称为基带处理芯片或基带芯片。基带子系统可以作为独立的芯片，该芯片可被称调制解调器(modem)或modem芯片。基带子系统可以按照modem芯片为单位来制造和销售。modem芯片有时也被称为基带处理器或移动处理器。此外，基带子系统也可以进一步集成在更大的芯片中，以更大的芯片为单位来制造和销售。这个更大的芯片可以称为系统芯片，芯片系统或片上系统(system on a chip，SoC)，或简称为SoC芯片。基带子系统的软件组件可以在芯片出厂前内置在芯片的硬件组件中，也可以在芯片出厂后从其他非易失性存储器中导入到芯片的硬件组件中，或者还可以通过网络以在线方式下载和更新这些软件组件。
此外，该无线通信设备中还可包括存储器，例如图11a中的内存和大容量存储器。此外，在应用子系统和基带子系统中，还可以分别包括一个或多个缓存。具体实现中，存储器可分为易失性存储器(volatile memory)和非易失性存储器(non-volatile memory，NVM)。易失性存储器是指当电源供应中断后，内部存放的数据便会丢失的存储器。目前，易失性存储器主要是随机存取存储器(random access memory，RAM)，包括静态随机存取存储器(static RAM，SRAM)和动态随机存取存储器(dynamic RAM，DRAM)。非易失性存储器是指即使电源供应中断，内部存放的数据也不会因此丢失的存储器。常见的非易失性存储器包括只读存储器(read only memory，ROM)、光盘、磁盘以及基于闪存(flash memory)技术的各种存储器等。通常来说，内存和缓存可以选用易失性存储器，大容量存储器可以选用非易失性存储器，例如闪存。
根据前述方法，图11b为本申请实施例提供的通信装置的结构示意图，如图11b所示，该通信装置可以为无线通信装置或网络设备，也可以为芯片或电路，比如可设置于无线通信装置的芯片或电路，再比如可设置于网络设备内的芯片或电路。无线通信装置可以为前述内容中提到的终端设备，或者为终端设备内的芯片或电路。图11b的通信装置可以为图11a的通信装置。
如图11b所示，该通信装置1301可以包括处理器1302，以及与处理器1302耦合的收发器1303。还可以包括存储器1304。
