Description

网络接入模式切换方法、装置、存储介质及电子设备
本公开要求申请日为2021年08月06日、申请号为202110903670.4、发明创造名称为“网络接入模式切换方法、装置、存储介质及电子设备”的中国发明专利申请的优先权。
技术领域
本申请涉及无线通信技术领域，具体而言，涉及一种网络接入模式切换方法、网络接入模式切换装置、计算机可读存储介质及电子设备。
背景技术
用户可以使用终端设备与基站进行通信，其中的基站可以为4G基站也可以为5G基站，若终端设备能够与5G基站建立连接，则可以使用5G网络实现通信；若终端设备与4G基站建立连接，就可以使用4G网络实现通信。
但是，实际应用中，5G网络本身不支持话音业务(即，VoLTE业务)，话音业务需要依据演进的分组系统回落(Evolved PacketSystem Fallback，EPS Fallback)的方式回落4G网络进行实现。基于终端设备接入了4G网络，若终端设备处于信号不佳的地域且多次无法连接4G网络时，会触发禁用计时器开始计时，计时过程中，终端设备禁用4G网络并搜寻5G网络，在搜寻到且接入到5G网络后，可以依据演进的分组系统回落的方式执行话音业务。
在终端设备禁用4G网络且未搜寻到5G网络的过程中，终端设备会搜寻2G/3G网络，若搜寻失败，则会导致话音业务失败。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本申请的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施方式使得本申请将更加全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施方式中。在下面的描述中，提供许多具体细节从而给出对本申请的实施方式的充分理解。然而，本领域技术人员将意识到，可以实践本申请的技术方案而省略所述特定细节中的一个或更多，或者可以采用其它的方法、组元、装置、步骤等。在其它情况下，不详细示出或描述公知技术方案以避免喧宾夺主而使得本申请的各方面变得模糊。
此外，附图仅为本申请的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
图1示出了适于用来实现本申请实施例的终端设备的计算机系统的结构示意图。
需要说明的是，图1示出的终端设备的计算机系统100仅是一个示例，不应对本申请实施例的功能和使用范围带来任何限制。
如图1所示，计算机系统100包括中央处理单元(CPU)101，其可以根据存储在只读存储器(ROM)102中的程序或者从储存部分108加载到随机访问存储器(RAM)103中的程序而执行各种适当的动作和处理。在RAM 103中，还存储有系统操作所需的各种程序和数据。CPU 101、ROM 102以及RAM 103通过总线104彼此相连。输入/输出(I/O)接口105也连接至总线104。
以下部件连接至I/O接口105：包括键盘、鼠标等的输入部分106；包括诸如阴极射线管(CRT)、液晶显示器(LCD)等以及扬声器等的输出部分107；包括硬盘等的储存部分108；以及包括诸如LAN卡、调制解调器等的网络接口卡的通信部分109。通信部分109经由诸如因特网的网络执行通信处理。驱动器110也根据需要连接至I/O接口105。可拆卸介质111，诸如磁盘、光盘、磁光盘、半导体存储器等等，根据需要安装在驱动器110上，以便于从其上读出的计算机程序根据需要被安装入储存部分108。
特别地，根据本申请的实施例，下文参考流程图描述的过程可以被实现为计算机软件程序。例如，本申请的实施例包括一种计算机程序产品，其包括承载在计算机可读介质上 的计算机程序，该计算机程序包含用于执行流程图所示的方法的程序代码。在这样的实施例中，该计算机程序可以通过通信部分109从网络上被下载和安装，和/或从可拆卸介质111被安装。在该计算机程序被中央处理单元(CPU)101执行时，执行本申请的方法和装置中限定的各种功能。
在网络覆盖或配置异常时，终端设备通常无法正常驻留LTE(Long Term Evolution，长期演进)网络。例如：某个LTE小区下，终端在发起附着(Attach)驻留或跟踪区更新(Tracking Area Update，TAU)，在随机接入过程中，由于收不到网络响应的某个msg消息(如msg2消息)，则可能影响终端正常驻留LTE网络；又例如，完成随机接入建立无线资源控制(Radio Resource Control，RRC)连接之后，LTE网络并未继续发起鉴权等后续操作而是直接释放了RRC连接等，则可能影响终端正常驻留LTE网络；如果因为上述异常情况等原因，终端重复发起Attach或TAU，失败次数达到5次之后，在满足启动条件的情况下会启动4G接入模式对应的计时器。启动4G接入模式对应的计时器后只能依赖计时器超时后恢复LTE网络。在计时器超时前，终端设备无法执行话音业务，给用户造成诸多不便。
为了解决这一问题，基于图1所示的终端设备系统，本申请实施例公开了一种网络接入模式切换方法。如图2所示，该网络接入模式切换方法可以应用于终端设备，包括：步骤S210～步骤S220。
步骤S210：当4G接入模式对应的计时器被触发生效时，禁用4G接入模式。
步骤S220：若检测到终端设备中的预设参数值满足生效条件，则禁用计时器并启动4G接入模式。
需要说明的是，本申请的技术方案，可以应用于各种通信系统，例如：全球移动通信系统(英文全称：Global System for Mobile Communication，缩写：GSM)，码分多址(英文全称：Code Division Multiple Access，缩写：CDMA)系统，宽带码分多址(英文全称：Wideband Code Division Multiple Access，缩写：WCDMA)，通用分组无线业务(英文全称：General Packet Radio Service，缩写：GPRS)，长期演进(英文全称：Long Term Evolution，缩写：LTE)等。
下面，对于本示例实施方式的上述步骤进行更加详细的说明。
在步骤S210之前，终端设备可以接收系统版本更新请求，当终端设备检测到接受操作时，可以对该系统版本更新请求进行响应，从而实现对终端设备的系统版本。更新后的系统版本中包括配置的预设参数(EnableT3402EarlyStop)；其中，预设参数(EnableT3402EarlyStop)可以包括多种状态，多种状态可以通过不同的预设参数值进行表示，本申请对于状态种类不作限定。
在一些实施例中，预设参数(EnableT3402EarlyStop)可以包括两种状态，即，生效状态和禁用状态。其中，生效状态可以通过第一数值(如，1)进行表示，禁用状态可以通过第二数值(如，2)进行表示。基于此，上述方法还包括：当检测到预设参数值等于 第一数值时，判定预设参数值满足生效条件；当检测到预设参数值等于第二数值时，判定预设参数值不满足生效条件。其中，需要说明的时，预设参数值可以由运营商进行设置。
基于此，可以在执行步骤S210，在步骤S210中，4G接入模式对应的计时器可以表示为T3402计时器，T3402计时器的计时方式为倒计时，T3402计时器对应于一个预设时长(如，12min)，当计时器被触发生效时，终端设备可以禁用自身的4G接入模式(S1-mode)，禁用4G接入模式后的终端设备不具备用4G接入能力(E-UTRA capability)。
在步骤S220检测到终端设备中的预设参数值满足生效条件之前，上述方法还包括：查询终端设备中存储的预设参数(EnableT3402EarlyStop)，获取与预设参数(EnableT3402EarlyStop)对应的预设参数值。其中，预设参数(EnableT3402EarlyStop)存储于终端设备相关的移动设备(Mobile Equipment，ME)或者全球用户识别卡(niversal Subscriber Identity Module，USIM)Universal Subscriber Identity Module(全球用户识别卡)中。
进而可以执行步骤S220，在步骤S220中，若检测到终端设备中的预设参数值(如，1或0)满足生效条件；其中，生效条件可以通过数值(如，1)进行表示。当预设参数值与生效条件中的数值一致，则可以判定预设参数值满足生效条件。在预设参数值满足生效条件的情况下，终端设备可以禁用计时器并启动4G接入模式，4G接入模式启动后的终端设备具备用4G接入能力(E-UTRA capability)。
进一步地，禁用计时器之后，上述方法还包括：当计时器被再次触发时，将计时器对应的禁用时长重置为预设值(如，12min)并基于重置后的计时器进行计时；若检测到预设参数值不满足生效条件，则禁用4G接入模式直到累计计时时长达到阈值为止。其中，基于重置后的计时器进行计时具体实施为：基于计时器对预设值进行倒计时。
可见，实施图2所示的方法，可以解除对4G接入模式的禁用，使得终端设备可以基于4G接入模式接入4G网络，避免因无法接入任何网络导致的话音业务失败问题。此外，还可以基于生效的预设参数值及时解除对4G接入模式的禁用，避免终端设备因接入失败而导致频繁尝试接入4G网络的过度耗电问题。
在图2的基础上，如图3所示，可以实现另一种网络接入模式切换方法，具体包括：步骤S310～步骤S380。
步骤S310：当4G接入模式对应的计时器被触发生效时，禁用4G接入模式。
步骤S320：向5G基站发送第一注册消息，以使得5G基站向5G移动管理网元转发第一注册消息；其中，第一注册消息用于表征终端设备不支持4G接入模式。
步骤S330：接收5G移动管理网元发送的第一反馈消息；其中，第一反馈消息用于表示不支持3GPP协议对应的话音业务。
步骤S340：禁用5G接入模式，并查询2G网络和3G网络。
步骤S350：若查询失败，则启动5G接入模式并确定预设参数值。
步骤S360：若检测到终端设备中的预设参数值满足生效条件，则禁用计时器并启动 4G接入模式。
步骤S370：向5G基站发送第二注册消息，以使得5G基站向5G移动管理网元转发第二注册消息；其中，第二注册消息用于表征终端设备支持4G接入模式。
步骤S380：接收5G移动管理网元发送的第二反馈消息；其中，第二反馈消息用于表示支持3GPP协议对应的话音业务。
下面，对于本示例实施方式的上述步骤进行更加详细的说明。
具体地，5G基站(gNB)可以作为中转站将终端设备发出的消息转发至5G移动管理网，5G移动管理网元属于5G核心网。当4G接入模式对应的计时器被触发生效时，可以禁用4G接入模式，并向5G网络进行注册。5G移动管理网元可以向终端设备反馈用于表示不支持3GPP协议对应的话音业务的第一反馈消息，即，可以理解为，当前无法实现EPS Fallback。基于此，终端设备可以搜寻2G网络和3G网络，若搜寻不到2G网络和3G网络，则可以再启动5G接入模式(N1-mode)并检测预设参数值是否为第一数值(如，1)，如果是，则判定预设参数值满足生效条件。进而可以实现对于计时器的禁用并启动4G接入模式，以实现接入4G网络。
此外，上述的步骤S380中的3GPP协议用于表征一种无线通信行业规范。在步骤S380之后，还可以包括：在由4G网络切换为5G网络之后，将预设参数值由第一数值(如，1)重置为第二数值(如，0)，若预设参数值＝0，则表示预设参数暂时失效。
可见，实施图3所示的方法，可以解除对4G接入模式的禁用，使得终端设备可以基于4G接入模式接入4G网络，避免因无法接入任何网络导致的话音业务失败问题。此外，还可以基于生效的预设参数值及时解除对4G接入模式的禁用，避免终端设备因接入失败而导致频繁尝试接入4G网络的过度耗电问题。
在图3的基础上，如图4所示，可以实现并列的网络接入模式切换方法，一个方案包含步骤S410，另一个方案包含步骤S421～步骤S427。
步骤S410：终端设备(UE)当4G接入模式对应的计时器被触发生效时，禁用4G接入模式，若检测到终端设备中的预设参数值满足生效条件，则禁用计时器并启动4G接入模式。
步骤S421：终端设备(UE)当4G接入模式对应的计时器被触发生效时，禁用4G接入模式，并向RAN网元发送第一注册消息；其中，第一注册消息用于表征终端设备不支持4G接入模式。
步骤S422：RAN网元转发第一注册消息。
步骤S423：AMF网元发送用于表示不支持3GPP协议对应的话音业务的第一反馈消息。
步骤S424：终端设备(UE)禁用5G接入模式，并查询2G网络和3G网络，若查询失败，则启动5G接入模式并确定预设参数值，若检测到终端设备中的预设参数值满足生效条件，则禁用计时器并启动4G接入模式。
步骤S425：终端设备(UE)向RAN网元发送第二注册消息。
步骤S426：RAN网元转发第二注册消息。
步骤S427：AMF网元发送用于表示支持3GPP协议对应的话音业务的第二反馈消息。
下面，对于本示例实施方式的上述步骤进行更加详细的说明。
在一个实施例中，针对步骤S410，终端设备(User Equipment，UE)当4G接入模式对应的T3402计时器被触发生效时，可以禁用S1-mode，若检测到终端设备中的“EnableT3402EarlyStop”＝1时，则禁用T3402计时器并启动S1-mode，以使得终端设备(UE)可以与E-UTRA(Evolved UMTS Terrestrial Radio Access Network)网元建立连接，进而基于E-UTRA网元与MME(Mobility Management Entity)网元进行基于4G网络的会话消息传递，从而完成话音业务。其中，E-UTRAN是一种演进的UMTS陆地无线接入网，即LTE中的移动通信无线网络，MME是3GPP协议LTE接入网络的关键控制节点，负责空闲模式的终端设备(UE)的定位、传呼过程、中继，一般也可以表示为4G移动性管理实体。
在另一个实施例中，针对步骤S421～步骤S427，终端设备(UE)可以当S1-mode对应的T3402计时器被触发生效时，禁用S1-mode，并向作为无线电接入网络实体出现的RAN网元(对应于上述的5G基站)发送第一注册消息，第一注册消息也可以表示为5G MM capability信元，该信元中包含特定内容“S1 mode not supported”，以使得第一注册消息用于表征终端设备不支持4G接入模式。进而，RAN网元接收到第一注册消息后可以转发第一注册消息至用于实现移动性管理功能的AMF网元。AMF网元接收到第一注册消息可以生成对应的第一反馈消息并反馈至终端设备(UE)，第一反馈消息中可以包含表征不支持基于3GPP协议的话音业务的特定字符。基于此，终端设备(UE)可以禁用5G接入模式(N1-mode)，并查询2G网络和3G网络，若查询失败，则表示附近没有运营商设立的与2G网络和3G网络相关的网元，那么，终端设备(UE)可以再启动N1-mode并确定预设参数值，若预设参数值为1，则禁用T3402计时器并启动S1-mode。进而，终端设备(UE)可以重新向RAN网元发送第二注册消息，第二注册消息也可以表示为5G MM capability信元，该信元中包含特定内容“S1 mode supported”，以使得第二注册消息用于表征终端设备支持4G接入模式。RAN网元在接收到第二注册消息后可以将第二注册消息转发至AMF网元，AMF网元在接收到第二注册消息后可以生成对应的第二反馈消息并反馈至终端设备(UE)。基于此，终端设备(UE)可以与E-UTRA(Evolved UMTS Terrestrial Radio Access Network)网元建立连接，进而基于E-UTRA网元与MME(Mobility Management Entity)网元进行基于4G网络的会话消息传递，从而完成话音业务。
需要说明的是，在图4中，RAN网元和AMF网元属于5G网元，E-UTRA网元和MME网元属于4G网元。
可见，实施图4所示的方法，可以解除对4G接入模式的禁用，使得终端设备可以基于4G接入模式接入4G网络，避免因无法接入任何网络导致的话音业务失败问题。此外， 还可以基于生效的预设参数值及时解除对4G接入模式的禁用，避免终端设备因接入失败而导致频繁尝试接入4G网络的过度耗电问题。
如图5所示，图5实现的是与图2相对应的一种网络接入模式切换装置。该网络接入模式切换装置500包括：禁用单元501和启动单元502。
禁用单元501，用于当4G接入模式对应的计时器被触发生效时，禁用4G接入模式；
禁用单元501，还用于在检测到终端设备中的预设参数值满足生效条件时，禁用计时器；
启动单元502，用于启动4G接入模式。
可见，实施图5所示的装置，可以解除对4G接入模式的禁用，使得终端设备可以基于4G接入模式接入4G网络，避免因无法接入任何网络导致的话音业务失败问题。此外，还可以基于生效的预设参数值及时解除对4G接入模式的禁用，避免终端设备因接入失败而导致频繁尝试接入4G网络的过度耗电问题。
