相关申请的交叉引用
本申请要求享有于2021年05月06日提交的名称为“一种网络接入方法和装置”的中国专利申请202110490829.4的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本申请实施例涉及信息处理领域，尤其涉及一种网络接入方法和装置。
背景技术
随着技术的不断发展，多卡槽的电子设备可以安装多个用户身份识别模块(Subscriber Identity Module，SIM)卡，让用户同时体验不同运营商服务的同时，也给一些业务带来了挑战。
比如，用户想使用Wi-Fi的语音业务(Voice over Wi-Fi，VoWiFi)的时候，可能会随机选择一个SIM卡发起VoWiFi业务，如果有任何一张SIM卡不能开展VoWiFi业务，都可能会导致VoWiFi业务开展的失败，这样一来，需要再次进行认证等流程，电子设备与网络进行交互的时间随之增多，VoWiFi业务接入的效率也随之降低。
由此，随着SIM卡的增多，VoWiFi业务接入效率低。
发明内容
本申请实施例提供一种网络接入方法和装置，以解决随着SIM卡的增多，VoWiFi业务接入效率低的问题。
第一方面，本申请实施例提供了一种网络接入方法，应用于电子设备，电子设备包括多个SIM卡，该方法可以包括：
获取目标ePDG地址，目标ePDG地址为第一SIM卡注册基于VoWiFi并通过认证的ePDG地址；控制第二SIM卡通过目标ePDG地址发起认证请求。
第二方面，本申请实施例提供了一种网络接入装置，应用于电子设备，电子设备包括多个用户身份识别模块SIM卡，该装置可以包括：
获取模块，用于获取目标演进型分组数据网关ePDG地址，目标ePDG地址为第一SIM卡注册基于无线保真的语音业务VoWiFi并通过认证的ePDG地址；
控制模块，用于控制第二SIM卡通过目标ePDG地址发起认证请求。
第三方面，本申请实施例提供了一种电子设备，该电子设备包括处理器、存储器及存储在存储器上并可在处理器上运行的程序或指令，该程序或指令被所述处理器执行时实现如第一方面所述的方法的步骤。
第四方面，本申请实施例提供了一种可读存储介质，该可读存储介质上存储程序或指令，该程序或指令被处理器执行时实现如第一方面所述的方法的步骤。
第五方面，本申请实施例提供了一种芯片，该芯片包括处理器和通信接口，通信接口和处理器耦合，处理器用于运行程序或指令，实现如第一方面所述的方法。
本申请实施例中，通过获取第一SIM卡注册基于无线保真的语音业务VoWiFi并通过认证的目标ePDG地址，然后控制第二SIM卡通过目标ePDG地址发起认证请求。由于目标ePDG地址为第一SIM卡发起的认证请求通过的网关地址，所以第二SIM卡向目标ePDG地址发起的认证请求通过的概率大大提高，进而可以减少和网络交互的时间，提高接入VoWiFi业务的效率。

本申请实施例提供的网络接入方法至少可以应用于下述应用场景中，下面进行说明。
目前，多卡槽的电子设备可以安装多个SIM卡，让用户在拥有一部电子设备，可以体验不同运营商服务的同时，也给一些业务带来了挑战。
其中，基于Wi-Fi的语音业务(Voice over Wi-Fi，VoWiFi)业务是电子设备一种比较常见的业务。VoWiFi有五种不同的网络架构，目前应用较为广泛，受到大部分电子设备厂商青睐的组网方案是S2b接口组网方案，也称作非信任域核心网络(EPC)接入方案。
其中，非信任域EPC接入方案，所有Wi-Fi(WIreless-Fidelity，无线保真)热点等非信任域设备均可以接入，通过演进型分组数据网关 (Evolevd Packet Data Gateway，ePDG)接入PDN网关(PDN Gateway，PGW)，实现和EPC的互通。由于非受信域接入网络和EPC互通采用S2b接口，因此这种组网也称为S2b接口组网方案。这种方案对无线局域网(Wireless Local Area Network，WLAN)没有改造要求，安全性高，支持无缝切换，解决了语音、数据业务的连续性问题。
这种方案很好地利用了现有的无线网络，只需要在原来的网络基础上，简单改造就能实现VoWiFi的功能，因此受到运营商和电子设备厂商的大力支持。在此方案中，电子设备通过非可信的无线网络接入到运营商可信的移动网络，将PGW作为WLAN和长期演进(Long Term Evolution，LTE)切换的锚点。其中，PGW是移动通信网络EPC中的重要网元。PGW为EPC网络的边界网关，提供用户的会话管理和承载控制、数据转发以及网络协议地址分配等功能。
基于上述S2b接口组网方案，在经过一系列认证和鉴权后，可以实现语音、视频以及短信等业务。VoWiFi业务的开展，仅需要增加ePDG和验证、授权和记账(Authentication Authorization and Accounting，3GPP AAA)网元，其中ePDG可以看做是VoWiFi网络和PGW之间的一个连接支持网元。它连接非授信WiFi网络的终结SWu接口，通过互联网密钥交换协议(IKEv2)消息与电子设备进行交互，获取电子设备的认证信息，然后将认证信息与3GPP AAA进行交互，从而完成对用户鉴权和认证。将电子设备通过互联网安全协议(Internet Protocol Security，IPSec)隧道传输的用户数据进行解封装，通过自身和PGW之间的GTP隧道传输重新封装后的用户数据。
因此，ePDG起着连接非可信WiFi网络和PGW网元的枢纽作用。ePDG的选择对于VoWiFi业务的开展，有很大影响。
对于包括多个SIM卡的电子设备而言，假设每张SIM卡能成功开展业务的概率为a、b、···、n，n为正整数。每个概率的取值范围在[0,1]。当只有一张SIM卡的时候，能成功进行VoWiFi业务的概率是a；当有两张卡时，能成功进行VoWiFi业务的概率在[a，ab]之间，依次类推，随着电子设备中的SIM卡的数量越多，能成功进行VoWiFi业务的概率则会越 低。
针对相关技术出现的问题，本申请实施例提供一种网络接入方法及装置，以解决相关技术中，随着SIM卡的增多，VoWiFi业务接入效率低的问题。
本申请实施例提供的方法，除了可以应用到上述应用场景之外，还可以应用到任何随着SIM卡的增多，VoWiFi业务接入效率低的场景中。
通过本申请实施例提供的方法，通过获取第一SIM卡注册基于无线保真的语音业务VoWiFi并通过认证的目标ePDG地址，控制第二SIM卡通过目标ePDG地址发起认证请求。由于目标ePDG地址为第一SIM卡发起的认证请求通过的网关地址，所以第二SIM卡向目标ePDG地址发起的认证请求通过的概率大大提高，进而可以减少和网络交互的时间，提高接入VoWiFi业务的效率。
基于上述应用场景，下面结合图1所示的架构图对本申请实施例提供的网络接入方法进行简要说明。
首先，对于电子设备100中的任一SIM卡而言，可以通过任意一个WiFi无线访问接入点(即网络200)连接到ePDG300。然后，ePDG300连接到PGW400。最后，通过PGW400接入到IMS核心网500。由于电子设备100到ePDG300之间是公共网络，存在不安全因素，因此会在电子设备100与ePDG300之间建立一个IPSec安全隧道，电子设备100可以通过IKEv2协议来完成身份认证和IPSec建立过程。当IPSec建立完成后，就可以和向IMS核心网注册VoWiFi业务以及进行后续的业务呼叫了。基于上述图1所示的方案，所有Wi-Fi热点等非信任域设备均可以接入，通过ePDG接入PGW，以实现和核心网的互通。这种方案对WLAN没有改造要求，安全性高，保证语音以及数据业务的连续性。
对于电子设备而言，响应于每个SIM卡对基于无线保真的语音业务VoWiFi的接入请求，查询ePDG地址，然后，控制每个SIM卡向所对应的ePDG地址发起认证请求；在第一SIM卡发起的认证请求通过且第二SIM卡发起的认证请求失败的情况下，控制第二SIM卡向认证请求通过的目标ePDG地址发起认证请求。由于获取认证请求通过的目标ePDG地址 的速度要远远快于重新查询ePDG地址的速度，所以第二SIM卡向目标ePDG地址发起的认证请求通过的概率大大提高，进而可以减少和网络交互的时间，提高接入VoWiFi业务的效率。
基于上述应用场景，下面对本申请实施例提供的网络接入方法进行详细说明。
图2为本申请一实施例提供的网络接入方法的流程图。
如图2所示，该网络接入方法可以包括步骤210-步骤220，该方法应用于网络接入装置，具体如下所示：
步骤210，获取目标ePDG地址，目标ePDG地址为第一SIM卡注册VoWiFi并通过认证的ePDG地址。
步骤220，控制第二SIM卡通过目标ePDG地址发起认证请求。
本申请提供的网络接入方法，通过获取第一SIM卡注册基于无线保真的语音业务VoWiFi并通过认证的目标ePDG地址，控制第二SIM卡通过目标ePDG地址发起认证请求。由于目标ePDG地址为第一SIM卡发起的认证请求通过的网关地址，所以第二SIM卡向目标ePDG地址发起的认证请求通过的概率大大提高，进而可以减少和网络交互的时间，提高接入VoWiFi业务的效率。
下面对本申请中涉及的专业词语进行简要介绍。
SIM卡是全球移动通信系统(Global System for Mobile Communications，GSM)的移动用户所持有的用户识别卡。GSM系统通过SIM卡来识别GSM用户。同一张SIM卡可在不同的电子设备上使用。电子设备只有插入SIM卡后，才能入网使用。SIM卡是电子设备连接到GSM网络的钥匙，在电子设备安装了SIM卡后，可以享受网络运营商提供的各种服务。
VoWiFi技术应运而生，该技术是利用现有的Wi-Fi(WIreless-Fidelity，无线保真)网络实现无线的VoIP语音通话，用户可以通过VoWiFi电子设备在WLAN网络的覆盖范围内随时进行漫游语音、视频通话。VoWiFi将WiFi作为接入网，最终是要接入IMS(IP Multimedia Subsystem，IP多媒体子系统)的，它是运营商可以控制和管理的IP语音 服务。VoWiFi技术由于通信成本低，而且又能使用户获得WLAN带来的方便性，所以越来越受到人们的关注。
下面，对步骤210-步骤220的内容分别进行描述：
首先，涉及步骤210。
在一种可能的实施例中，在步骤210之前，还可以包括以下步骤：
获取每个SIM卡向ePDG地址发起认证请求的认证结果；
根据认证结果确定第一SIM卡和第二SIM卡；第一SIM卡的认证结果为认证请求通过，第二SIM卡的认证结果为认证请求失败；
确定第一SIM卡对应的目标ePDG地址。
在所有SIM卡都完成了第一轮的ePDG认证流程之后，电子设备就可以根据认证结果得知哪些SIM卡认证的ePDG是可用的。即可以确定认证结果为认证请求通过的第一SIM卡对应的目标ePDG地址。认证请求通过的第一SIM卡可以通过目标ePDG地址注册VoWiFi。
其中，在上述涉及到的获取每个SIM卡向ePDG地址发起认证请求的认证结果的步骤之前，还可以包括以下步骤：
响应于每个SIM卡对VoWiFi的接入请求，查询ePDG地址，得到地址查询结果；控制每个SIM卡向地址查询结果对应的ePDG地址发起认证请求。
电子设备的多个SIM卡分别发起VoWiFi业务，通过本地配置的静态查询方式或通过域名系统(Domain Name System，DNS)的动态查询方式，来查询ePDG信息，得到地址查询结果。在得到地址查询结果之后，就可以控制每个SIM卡向地址查询结果对应的ePDG地址发起认证请求。
在一种可能的实施例中，在多个SIM卡发起的认证请求失败的情况下，查询ePDG地址，确定更新后的ePDG地址；控制多个SIM卡向更新后的ePDG地址发起认证请求。
如果多个SIM卡发起的认证请求均失败，则可以重新通过本地配置的静态查询方式或通过DNS的动态查询方式，来查询ePDG信息，以确定更新后的ePDG地址。然后控制多个SIM卡向更新后的ePDG地址发起认证请求。
接着，涉及步骤220。
由于ePDG无效而不能注册VoWiFi的第二SIM卡，可以优先尝试其他成功注册上VoWiFi的第一SIM卡的目标ePDG地址，从中选择其中合适的ePDG进行尝试。由于目标ePDG地址是第一SIM卡先前已经认证通过的，所以第二SIM卡向目标ePDG地址发起认证请求时，认证结果为认证通过的概率大大提高。
也就是说，通过上述多卡先验的方法，假设每张SIM卡能成功开展业务的概率为a、b、···、n，n为正整数。每个概率的取值范围在[0，1]。当只有一张SIM卡的时候，不能成功进行VoWiFi业务的概率是1-a；当有两张卡时，不能成功进行VoWiFi业务的概率在[(1-a)(1-b)，1-a]之间，依次类推，只需要一张卡VoWiFi能正常开展，其他的卡都认为能正常开展。此时VoWiFi业务的失败概率为(1-a)(1-b)···(1-n)，卡数越多，失败的概率反而越低，这充分利用了多卡的优势，能提高手机多卡情况下VoWiFi业务成功开展的概率。
其中，步骤220中，具体可以包括以下步骤：
确定第一SIM卡所属的第一运营商，以及第二SIM卡所属的第二运营商；在第一运营商与第二运营商一致的情况下，或者，在第一运营商与第二运营商满足预设合约条件的情况下，控制第二SIM卡向目标ePDG地址发起认证请求。
其中，如图3所示，步骤220中，具体可以包括以下步骤：
步骤310，确定第一SIM卡所属的第一运营商，以及第二SIM卡所属的第二运营商。
步骤320，在第一运营商与第二运营商一致的情况下，控制第二SIM卡向目标ePDG地址发起认证请求。
即在第一SIM卡与第二SIM卡所属于相同的运营商的情况下，可以控制第二SIM卡向目标ePDG地址发起认证请求。
另外，如图4所示，步骤220中，具体可以包括以下步骤：
步骤410，确定第一SIM卡所属的第一运营商，以及第二SIM卡所属的第二运营商。
步骤420，在第一运营商与第二运营商满足预设合约条件的情况下，控制第二SIM卡向目标ePDG地址发起认证请求。
即在第一SIM卡与第二SIM卡所属的运营商属于签订了合约，彼此互相认可的运营商的情况下，可以控制第二SIM卡向目标ePDG地址发起认证请求。
由此，在电子设备包括多个SIM卡的情况下，只要有SIM卡(第一SIM卡)成功注册上了VoWiFi，并且在第一运营商与第二运营商一致的情况下，或者在第一运营商与第二运营商满足预设合约条件的情况下，其他的SIM卡(第二SIM卡)就可以借鉴第一SIM卡的目标ePDG地址，发起VoWiFi注册。由于电子设备知道所有成功注册上VoWiFi的SIM卡所选择的目标ePDG地址，因此由于ePDG地址不可用而导致不能注册VoWiFi的第二SIM卡，可以选择先验的已经认证通过的目标ePDG地址，发起新的请求，这样可以大大提高VoWiFi的接入成功率和效率，从而改善用户体验。
在另一种可能的实施例中，在步骤220之后，还可以包括以下步骤：
在第二SIM卡向目标ePDG地址发起认证请求失败的情况下，在认证结果中重新查询第二SIM卡的ePDG地址，确定第二SIM卡的更新后的ePDG地址，更新后的ePDG地址为认证结果中除目标ePDG地址以外的认证请求通过的ePDG地址；控制第二SIM卡向更新后的ePDG地址发起认证请求。
电子设备中由于无效ePDG不能注册上VoWiFi的第二SIM卡可以先尝试目标ePDG地址，如果第二SIM卡向目标ePDG地址发起认证请求也失败，则可以重新查询第二SIM卡的ePDG地址，从认证结果中确定除目标ePDG地址以外的认证请求通过的ePDG地址，即第二SIM卡的更新后的ePDG地址。然后控制第二SIM卡向更新后的ePDG地址发起认证请求。
另外，如果第二SIM卡向更新后的ePDG地址发起认证请求也失败，则可以再次按原来的静态查询或动态DNS查询来查询ePDG地址，确定更新后的ePDG地址，然后控制第二SIM卡向更新后的ePDG地址发起认证 请求。
综上，在本申请实施例中，通过获取第一SIM卡注册基于无线保真的语音业务VoWiFi并通过认证的目标ePDG地址，然后控制第二SIM卡通过目标ePDG地址发起认证请求。由于目标ePDG地址为第一SIM卡发起的认证请求通过的网关地址，所以第二SIM卡向目标ePDG地址发起的认证请求通过的概率大大提高，进而可以减少和网络交互的时间，提高接入VoWiFi业务的效率。
