技术领域
本发明涉及通信技术领域，尤其涉及一种网关接入方法及电子设备。
背景技术
目前VoWiFi(无线语音)业务主要有三种组网方案：非可信接入3GPP(第三代移动通信)网络(S2b接口，S2b接口是VoWiFi非可信接入方案中ePDG与分组数据网关PGW之间的接口)，可信接入3GPP网络(S2a接口，S2a接口是VoWiFi可信接入方案中终端网关TGW与PGW之间的接口),网络直接接入IP多媒体子系统IMS(S2c接口，S2c接口是VoWiFi IMS直连方案中UE与PGW之间的接口)。针对这三种组网方案从技术方面来进行分析，尤其是从对网络的影响和终端成熟度来看，对于已经部署大量WLAN(无线局域网)接入点的运营商来说，采用可信接入3GPP网络(S2a接口)方案，要升级改造或者直接替换全网WLAN接入点设备，施工周期长、成本高、难度大；而采用非可信接入3GPP网络(S2b接口)方案，则可以结合公共Wi-Fi(无线)网络的开放性和运营商核心网的高可靠性、QoS(服务质量)保证等特性，以较低成本实现语音在WLAN和LTE(长期演进)网络间的无缝切换。
因此，非可信接入3GPP网络(S2b接口)方案将逐步取代可信接入3GPP网络(S2a接口)方案，成为目前业界公认的较可行的VoWiFi方案。在该方案中，用户终端通过非信任域Wi-Fi网络接入到运营商的3GPP网络，认证鉴权后将呼叫请求路由到IMS进行处理，实现语音、短信、补充业务等IMS业务；并且在非可信接入3GPP网络(S2b接口)方案中，为实现VoWiFi业务，仅需要新增ePDG(演进型分组数据网关)和3GPP验证、授权和记账(Authentication Authorization and Accounting，AAA)网元就可以。其中，新增ePDG网元扮演 着非常重要的角色，它是面向非授信WiFi网络终结SWu接口(UE与ePDG之间的接口)的网关，在控制面，通过因特网秘钥交换第二版(Internet Key Exchange，IKEv2)消息与终端交互，获取可扩展身份验证协议(Extensible Authentication Protocol，EAP)认证信息，并将信息封装成Diameter消息与3GPP AAA认证服务器(Authentication Authorization and Accounting Server，AAA Server)和归属签约用户服务器(Home Subscriber Server，HSS)交互，实现用户认证；在用户面，对封装用户数据的因特网协议安全(Internet Protocol Security，IPSec)隧道进行解封装，并重新封装成GPRS隧道协议(GPRS Tunneling Protocol，通用无线分组业务(General Packet Radio Service，GPRS)GTP)隧道发送至分组数据网关(Packet Gateway，P-GW)。
故，ePDG选择对VoWiFi等non-3GPP(非3GPP)业务有着重要的影响，但是，现有的ePDG选择接入的一些方案存在效率低等问题，影响了VoWiFi等non-3GPP业务的效率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明针对现有的技术中ePDG选择接入方案存在效率低的问题，提供一种一种网关接入方法，应用于电子设备，如图1所示，包括：
步骤11：根据预先记录的至少一个演进型分组数据网关ePDG的优先级等级，确定目标ePDG。
步骤11的执行可以是在发起非第三代移动通信non-3GPP业务的情况下，但并不以此为限。具体的，可以是依据所述优先等级的高低，优先确定优先等级高的ePDG为目标ePDG，但并不以此为限。这样能够保证优先接入性能较好的ePDG，提升业务性能。
具体的，所述根据预先记录的至少一个演进型分组数据网关ePDG的优先级等级，确定目标ePDG，包括：根据预先记录的至少一个ePDG的优先级等级，从所述至少一个ePDG中确定一个ePDG为所述目标ePDG。
步骤12：根据预先记录的地址信息，向所述目标ePDG发起接入流程；其中，所述优先级等级包括依据所述至少一个ePDG的接入参数信息确定的优先级等级；所述地址信息包括所述目标ePDG的地址信息。
具体的，所述接入参数信息包括负载量信息(即负荷信息)和/或接入时的响应时长信息。
本发明实施例提供的所述网关接入方法通过根据预先记录的至少一个演进型分组数据网关ePDG的优先级等级，确定目标ePDG；根据预先记录的地址信息，向所述目标ePDG发起接入流程；其中，所述优先级等级包括依据所述至少一个ePDG的接入参数信息确定的优先级等级；所述地址信息包括所述目标ePDG的地址信息；能够实现当电子设备再次发起non-3GPP业务时会优先使用预先记录的ePDG进行业务，一定程度上可以增加non-3GPP业务的注册成功率；同时能够减少ePDG地址查询的过程和时间，提高UE与ePDG的交互效率，进而提升non-3GPP业务的效率，增加用户体验；很好的解决了现有技术中ePDG选择接入方案存在效率低的问题。
进一步的，所述方法还包括：向至少一ePDG发起接入流程；在接入成功 的情况下，记录所述ePDG的地址信息和接入参数信息。
在此说明，“向至少一ePDG发起接入流程”可以是在“确定目标ePDG”之前执行的，具体可以是“在发起非第三代移动通信non-3GPP业务的情况下”执行的，但并不以此为限。
这样能够便于后续地址信息和接入参数信息的使用。
进一步的，所述方法还包括：在接入所述目标ePDG失败的情况下，根据所述优先级等级，重新确定目标ePDG；并向重新确定的目标ePDG发起接入流程；其中，重新确定的目标ePDG的优先级等级低于前一次确定的目标ePDG的优先级等级。
这样能够进一步保证接入ePDG的成功率。
具体的，所述在接入所述目标ePDG失败的情况下，根据所述优先级等级，重新确定目标ePDG；并向重新确定的目标ePDG发起接入流程，包括：循环执行在接入所述目标ePDG失败的情况下，根据所述优先级等级，重新确定目标ePDG；并向重新确定的目标ePDG发起接入流程；直至预先记录的ePDG轮询完毕；通过静态查询或动态域名系统DNS查询ePDG信息，得到所分配的ePDG地址；根据所述所分配的ePDG地址，向对应ePDG发起接入流程。
这样能够最大程度的保证接入ePDG的正常实现。
下面对本发明实施例提供的所述网关接入方法进行进一步说明，电子设备以终端UE为例，关于接入参数信息以响应时长信息为例，关于地址信息和响应时长信息以体现为列表形式为例。
针对上述技术问题，本发明实施例提供了一种网关接入方法，具体可实现为一种ePDG选择的方法，通过该方案可以提升VoWiFi等non-3GPP业务的效率，本方案主要涉及：
在UE侧增加一个ePDG List(ePDG列表){ePDG1,ePDG2,…,ePDGn},该List用于记录UE使用过的ePDG地址(即上述地址信息)和ePDG响应时间信息(即上述响应时长信息)等，然后根据ePDG响应时间等信息(还可以包括负载量等信息)排序在List中，这样当UE再次发起non-3GPP业务时会优先使用List中的ePDG进行业务，通过该方案提升VoWiFi等non-3GPP业务(还可以包括无线视频视图VVWiFi等非3GPP业务)的注册成功率和效率， 从而增加用户体验。
具体的，本发明实施例提供的方案可如图2所示，包括：
步骤21：UE发起VoWiFi等non-3GPP业务，向ePDG发起请求附着流程(即发起接入流程)。
具体的，UE发起VoWiFi等non-3GPP业务，通过静态查询或动态DNS(域名系统)查询ePDG信息，然后向所分配的ePDG地址发起请求附着流程。
步骤22：ePDG收到请求后向UE返回响应信令。
也就是，ePDG收到请求信令后，会向UE返回相应的响应信令。
步骤23：UE收到响应信令后，UE会创建一个ePDG LIST，可将ePDG地址信息和响应时间信息一一对应排列好加入该LIST。
具体的，当UE收到响应信令后，UE会创建一个ePDG LIST{ePDG1,ePDG2,…,ePDGn}，其中n为列表的长度，n值不宜过大(n＝3-10左右适中，具体由实施方确定)，然后将所返回响应的ePDG的身份信息(比如地址信息)和ePDG响应时间(请求与响应之间的时间)一一对应，并按响应时间由低到高排列在ePDG LIST中。
步骤24：UE再次发起VoWiFi等non-3GPP业务时，直接向UE侧保存的ePDG LIST中的ePDG发起请求附着流程。
具体的，UE再次发起VoWiFi等non-3GPP业务时，直接向UE侧保存的ePDG LIST{ePDG1,ePDG2,…,ePDGn}中的ePDG发起请求附着流程：首先选择向ePDG1发起请求附着流程，如果ePDG1失败后，再尝试ePDG2，如果再失败直至尝试到ePDGn为止，之后如果还失败，则按UE原来的静态查询或动态DNS查询获取ePDG信息(具体可参见步骤21，在此不再赘述)。
由上可知，本发明实施例提供的方案：
(1)UE侧保存了响应时间最优的ePDG，UE发起non-3GPP业务时，一定程度上可以增加VoWiFi等non-3GPP业务的注册成功率；
(2)UE侧保存了响应时间最优的ePDG，当UE再次发起non-3GPP业务时，减少了ePDG地址查询的过程和时间，提高UE与ePDG的交互效率。
