发明提供了一种接入网络的方法、终端及接入点，能够使得终端快速识别并接入VoWiFi网络，从而提升用户体验。
为了使本技术领域的人员更好地理解本发明方案，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地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，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做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明说明书、权利要求书和附图中出现的术语“第一”、“第二”和“第三”等是用于区别不同的对象，而并非用于描述特定的顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本发明的一个实施例中，所述接入网络的方法包括：接入点发送探测消息，所述探测消息包含所述接入点的基于无线保真的语音通信VoWiFi(Voice over WiFi)的能力以使得终端根据所述接入点的VoWiFi能力确定是否接入所述接入点；所述接入点接收所述终端发起的接入所述接入点的请求；所述接入点根据所述请求与所述终端建立连接。其中，需要指出的是，VoWiFi是将WiFi作为接入网，最终是要接入IMS(IP Multimedia Subsystem，IP多媒体子***)的，它是运营商可以控制和管理的IP语音服务。
如图1所示，图1是本发明一个实施例提供的一种接入网络的方法的流程示意图。其中，如图1所示，本发明的一个实施例提供的一种接入网络的方法包括以下内容：
101、无线保真WiFi接入点发送探测消息，所述探测消息包含所述接入点的基于无线保真的语音通信VoWiFi的能力以使得终端根据所述接入点的VoWiFi能力确定是否接入所述接入点；
其中，VoWiFi的能力可以是信号的强弱。
其中，需要指出的是接入点为基于无线保真的语音通信VoWiFi(Voice over WiFi)。
其中，可以理解的是VoWiFi接入点发送的探测消息可以是信标帧也可 以是Probe Response探测响应消息；其中，所述信标帧或Probe Response探测响应消息携带VoWiFi能力的字段。
其中，可以理解的是VoWiFi接入点可以是在广播帧中增加接入VoWiFi能力的字段。
102、所述接入点接收所述终端发起的接入所述接入点的请求；
其中，需要指出的是，终端主动扫描周围的接入点，并接收接入点发送的探测消息，根据探测消息确定改接入点具备VoWiFi能力，当该接入点具备VoWiFi能力时，向该接入点发送接入请求。
103、所述接入点根据所述请求与所述终端建立连接。
其中，可选的，在建立连接前，接入点会对终端进行认证。例如VoWiFi网络对终端的认证使用EAP-AKA(Improved Extensible Authentication Protocol Method for 3rd Generation Authentication and Key Agreement，扩展认证协议-认证与密钥协商)机制，通过AAA(Authentication、Authorization、Accounting，认证、授权、计费)服务器完成授权认证。因此对于公共可信VoWiFi热点，对应WiFi路由器需要配置成EAP-AKA鉴权方式，即通过SIM卡和AAA服务器完成鉴权认证过程，整个过程不需要用户输入密码，但需要用户手动选择对应的热点发起连接。例如，所述接入所述接入点的请求中包含终端的客户识别模块SIM卡的鉴权向量；所述接入点根据所述请求与所述终端建立连接，包括：所述接入点根据所述SIM卡的鉴权向量对所述终端进行验证；当验证通过时，所述接入点与所述终端建立连接。
可以看出，本实施例的方案中，接入点发送探测消息，所述探测消息包含所述接入点的基于无线保真的语音通信VoWiFi的能力以使得终端根据所述接入点的VoWiFi能力确定是否接入所述接入点；所述接入点接收所述终端发起的接入所述接入点的请求；所述接入点根据所述请求与所述终端建立连接。因此，接入点发送包含所述接入点的VoWiFi的能力的探测消息，终端根据探测消息快速识别并接入VoWiFi，从而提升用户的体验。
如图2所示，图2是本发明一个实施例提供的一种接入网络的方法的流程示意图。其中，如图2所示，本发明的一个实施例提供的一种接入网络的方法包括以下内容：
201、终端扫描预设范围内的无线保真WiFi网络接入点，以获取所述接入点发送的探测消息，所述探测消息包含所述接入点的基于无线保真的语音通信VoWiFi的能力；
其中，VoWiFi的能力可以是信号的强弱。
其中终端主动扫描时接入点时，主动向各接入点发送探测请求Probe Request，接入点收到探测请求Probe Request后，接入点向终端回探测响应Probe Response或Beacon信标帧。终端收到Beacon信标帧或探测响应Probe Response时从中解析VoWiFi能力。
202、所述终端选择扫描到的VoWiFi能力大于预设阈值的接入点进行连接。
其中，需要指出的是，所述终端选择扫描到的VoWiFi能力最强的接入点进行连接之前，所述方法还包括：
所述终端根据所述接入点的VoWiFi的能力，确定VoWiFi列表；
所述终端确定所述VoWiFi列表中VoWiFi能力大于预设阈值的接入点。
可以看出，本实施例的方案中，终端扫描预设范围内的无线保真WiFi网络接入点，以获取所述接入点的基于无线保证的语音通信VoWiFi的能力；所述终端选择扫描到的VoWiFi能力大于预设阈值的接入点进行连接。因此，终端选择扫描到的VoWiFi能力大于预设阈值的接入点进行连接，从而能够使得终端快速连接到信号较好VoWiFi，从而提升用户的体验。
如图3所示，图3是本发明一个实施例提供的一种接入网络的方法的流程示意图。其中，如图3所示，本发明的一个实施例提供的一种接入网络的方法包括以下内容：
301、终端接收预设范围内的无线保真WiFi网络接入点发送的探测消息；其中，所述探测消息中包含所述接入点的语音通信VoWiFi的能力；
其中，探测消息可以是广播消息，该广播消息中包含一个字段，该字段用于表示VoWiFi的能力；
302、所述终端根据接收到的所述接入点的VoWiFi的能力，确定VoWiFi列表；
例如，终端接到多个网络发送的探测消息，终端就可以根据探测消息 确定每个接入点的VoWiFi的能力，然后结合每个接入点的VoWiFi的能力确定一张VoWiFi列表；其中该VoWiFi列表的格式可以是：WiFi网络标识和VoWiFi的能力大小。
303、所述终端确定所述VoWiFi列表中VoWiFi能力大于预设阈值的接入点；
其中，VoWiFi的能力可以是信号的强弱。
例如，假设5格位最强信号，预设阈值为3格信号。又例如，假设3格位最强信号，预设阈值为2格信号。其中，衡量能力的方式有很多，在此不一一例举。
304、所述终端选择VoWiFi能力大于预设阈值的接入点进行连接。
其中，连接的过程可以通过EAP-AKA机制，通过AAA服务器完成授权认证。因此对于公共可信VoWiFi热点，对应WiFi路由器需要配置成EAP-AKA鉴权方式，即通过SIM卡和AAA服务器完成鉴权认证过程，整个过程不需要用户输入密码，但需要用户手动选择对应的热点发起连接。例如，所述终端向接入点发送连接请求，该请求中包含终端的客户识别模块SIM卡的鉴权向量；所述接入点根据所述SIM卡的鉴权向量对所述终端进行验证；当验证通过时，所述接入点与所述终端建立连接。
可以看出，本实施例的方案中，终端接收预设范围内的WiFi网络发送的探测消息；其中，所述探测消息中包含所述接入点的语音通信VoWiFi的能力；所述终端根据接收到的所述接入点的VoWiFi的能力，确定VoWiFi列表；所述终端确定所述VoWiFi列表中VoWiFi能力大于预设阈值的接入点；所述终端选择VoWiFi能力大于预设阈值的接入点进行连接。因此，终端通过接收WiFi网络发送的探测消息以确定具备VoWiFi的能力接入点，并选择VoWiFi能力大于预设阈值的接入点进行连接，从而能够使得终端快速连接到信号较好VoWiFi，从而提升用户的体验。
在本发明的另一实施例中，本发明方案提供一种终端自动选择具备VoWiFi能力的接入点进行接入的方法。基本原理是在VoWiFi热点(即接入点)发送信标帧或Probe Response探测响应消息时携带接入VoWiFi的能力，终端在扫描时检测各热点的VoWiFi能力，并自动筛选出VoWiFi热点 列表，按照最佳信号值选择热点自动发起连接过程。通过本发明方案，终端可自动选择VoWiFi热点接入IMS(IP Multimedia Subsystem，IP多媒体子***)，可防止非VoWiFi热点对用户的干扰，也无需用户手动选择，增加用户体验。其中，指出的是，：IMS是一种全新的多媒体业务形式，它能够满足现在的终端客户更新颖、更多样化多媒体业务的需求。
