带宽控制方法和带宽控制设备

技术领域
本发明涉及移动通信领域，尤其涉及一种带宽控制方法和带宽控制设备。
背景技术
随着移动宽带用户和数据业务流量急速增长，传统蜂窝网络的速率逐渐成为移动宽带发展的瓶颈。移动宽带传输成本高，而无线局域网(Wireless Local Area Network，WLAN)凭借价格低廉、组网灵活、支持高速无线数据接入及频段开放等独特魅力，在金融、医疗、制造等行业获得广泛的应用。越来越多的网络运营商将WLAN定位为2G/3G移动网的补充。
无线高保真(Wireless Fidelity，Wi-Fi)分流是指移动运营商通过和第三方合作或者自建WLAN的方式，允许网内移动用户使用WLAN网络，分流移动网数据流量负荷，降低运营成本，缓减扩容压力的目的。当前，运营商构建Wi-Fi分流网的主要方案是自建公众Wi-Fi热点。该方案投资大，热点覆盖范围有限，难以满足运营商的分流需求。考虑到大部分运营商具有丰富的固定宽带用户资源，如果利用固定宽带用户网络进行Wi-Fi分流网络建设，即Wi-Fi分流热点寄宿固定宽带用户方案，可以为运营商节约大量新建网络投资，解决Wi-Fi热点铺设难，无法大面积覆盖等难题。
在该方案中，运营商通过改造固定宽带用户家庭网关设备，在用户家庭网关中增加公众Wi-Fi热点，通过在家庭网关和Wi-Fi分流网关之间发起建Soft-GRE隧道，把移动用户的Wi-Fi数据通过固定宽带接入网回传至运营商Wi-Fi分流网关，从而实现移动用户流量的分流。可有效解决Wi-Fi热点覆盖不足，新建承载网络投资大的难题。
然而，在该技术中，由于Wi-Fi分流热点寄宿于固定宽带用户的家庭网关设备中，需要使用该固定宽带用户的宽带连接承载业务流量，势必挤占宽带用户带宽，导致宿主用户的体验受影响。

具体实施方式
本发明实施例提供了一种带宽控制方法和带宽控制设备，用于降低移动终端的接入对固定终端的用户体验的影响。
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。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，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、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参阅图1，本发明中带宽控制方法的一个实施例包括：
101、带宽控制设备获取移动终端的接入请求，所述接入请求用于指示所述移动终端请求通过固定终端的家庭网关接入互联网；
本实施例中，该带宽控制设备可以是运营商用于控制带宽的设备。固定终端的家庭网关增加有运营商公众Wi-Fi热点，即该家庭网关可以将移动用户的Wi-Fi数据通过固定宽带接入网回传至运营商Wi-Fi分流网关，再通过该运营商Wi-Fi分流网关发送至互联网，以使得移动终端能够通过固定终端的家庭网关接入互联网。在移动终端需要接入互联网时，该移动终端发送接入请求至带宽控制设备，该接入请求用于请求通过该固定终端的家庭网关接入互联网；带宽控制设备获取该移动终端的接入请求。其中，请求通过该固定终端的家庭网关进入互联网的移动终端的数量可以为一个或者至少两个。
102、带宽控制设备获取固定终端的签约带宽；
固定终端与运营商签有协议，协定运营商为该固定终端的家庭网关分配固定的使用带宽，该固定的使用带宽即为固定终端的签约带宽。若分配给固定终端的使用带宽一直保持为该固定终端的签约带宽，那么，在移动终端请求通过该固定终端的家庭网关接入互联网时，会侵占该固定终端的签约带宽，使用该固定终端的宽带连接承载业务流量，进而影响该固定终端的使用体验。因此，为避免该固定终端的使用体验遭受影响，带宽控制设备需对分配给该固定终端的带宽进行调整。而在调整之前，带宽控制设备需先获取固定终端的签约带宽。
103、带宽控制设备将分配给固定终端的带宽调整为第二带宽，该第二带宽大于固定终端的签约带宽；
在获取到固定终端的签约带宽后，带宽控制设备根据该固定终端的签约带宽对分配给该固定终端的带宽进行调整，使得在有移动终端请求接入时，带宽控制设备给该固定终端分配的带宽从固定终端的签约带宽调整为第二带宽，其中该第二带宽大于固定终端的签约带宽。当没有移动终端请求接入时，带宽控制设备将分配给该固定终端的带宽调整回该固定终端的签约宽带宽。
本实施例中，在移动终端请求从固定终端的家庭网关无线接入互联网时，通过将固定终端的分配带宽动态调整，以使得分配给该固定终端的带宽大于其签约带宽，降低了移动终端用户的接入对使用固定终端的用户的体验的影响；同时，相比长期给固定终端分配大于其签约带宽的带宽，避免了在没有移动终端接入时给运营商接入网络造成的带宽浪费。
该实施例中，当有移动终端请求接入时，带宽控制设备分配给固定终端的带宽大于其签约带宽；那么，固定终端实际使用的资源可能会大于运营商与其签约的资源，即可能会侵占接入的移动终端的带宽，影响移动终端的用户体验。因此，可选地，该实施例中的宽带控制方法还包括：
104、带宽控制设备控制固定终端允许使用的带宽为该固定终端的签约带宽；
在有移动终端接入时，带宽控制设备分配给固定终端的带宽为第二带宽。但是，带宽控制设备对固定终端进行限速，使得固定终端能够使用的带宽为该固定终端的签约带宽。
这样，能够避免固定终端会侵占带宽控制设备原本为移动终端所分配的带宽，避免固定终端对移动终端的用户体验造成影响。
该实施例中，带宽控制设备将分配给固定终端的带宽调整为第二带宽。实际运用中，有多种方法来计算该第二带宽，下面对本发明实施例中带宽控制方法进行描述。
请参阅图2，本发明的另一个实施例的带宽控制方法包括：
201、带宽控制设备获取移动终端的接入请求，该接入请求用于指示该移动终端请求通过固定终端的家庭网关接入互联网；
本实施例中，该带宽控制设备可以是运营商用于控制带宽的设备。固定终端的家庭网关增加有运营商公众Wi-Fi热点，即该家庭网关可以将移动用户的Wi-Fi数据通过固定宽带接入网回传至运营商Wi-Fi分流网关，再通过该运营商Wi-Fi分流网关发送至互联网，以使得移动终端能够通过固定终端的家庭网关接入互联网。在移动终端需要接入互联网时，该移动终端发送接入请求至带宽控制设备，该接入请求用于请求通过该固定终端的家庭网关接入互联网；带宽控制设备获取该移动终端的接入请求。其中，请求通过该固定终端的家庭网关进入互联网的移动终端的数量可以为一个或者至少两个。
202、带宽控制设备获取固定终端的签约带宽；
固定终端与运营商签有协议，协定运营商为该固定终端的家庭网关分配一定的使用带宽，该使用带宽即为固定终端的签约带宽。若分配给固定终端的使用带宽一直保持为该固定终端的签约带宽，那么，在移动终端请求通过该固定终端的家庭网关接入互联网时，会侵占该固定终端的签约带宽，使用该固定终端的宽带连接承载业务流量，进而影响该固定终端的使用体验。因此，为避免该固定终端的使用体验遭受影响，带宽控制设备需对分配给该固定终端的带宽进行调整。而在调整之前，带宽控制设备需先获取固定终端的签约带宽。
203、带宽控制设备获取移动终端的签约带宽；
每个移动终端与运营商签有协议，协定运营商为该移动终端分配一定的使用带宽，该使用带宽即为该移动终端的签约带宽。不同的移动终端的签约带宽可以相同，也可以不同。
204、带宽控制设备根据移动终端的签约带宽计算第一带宽；
为了保证固定终端的用户体验，避免移动终端的签约带宽较大或者移动终端的数量较多而导致移动终端过多地占用固定终端的宽带连接，并保证移动终端的用户体验，带宽控制设备在对分配给固定终端的带宽进行调整时，需结合移动终端的签约带宽来计算第一带宽，然后再根据该第一带宽和固定终端的签约带宽来计算第二带宽。
带宽控制设备根据各移动终端的签约带宽来计算第一带宽的方法有多种。具体举例 来说，带宽控制设备选取各移动终端的签约带宽中数值最大的签约带宽作为第一带宽；或者，带宽控制设备将各移动终端的签约带宽的加权值作为第一带宽。当然，以上方法仅为举例，并不作限制。
其中，带宽控制设备将各移动终端的签约带宽的加权值作为第一带宽的方法也有多种。例如，带宽控制设备将各移动终端的签约带宽的和作为第一带宽。实际运用中，由于同一时间内各移动终端所使用的最大带宽并不一定为其签约带宽，因此第一带宽也可以不是各移动终端的签约带宽的和，而可以是小于这些移动终端的签约带宽的和，也即至少部分移动终端的签约带宽的加权值可以小于1。因此，可以是将各移动终端的签约带宽的平均值作为第一带宽，或者，根据各移动终端的签约带宽来将各移动终端进行分级，并根据各移动终端的级别来确定其加权值，其中级别越高的移动终端的加权值越大。这样，可以避免运营商的宽带资源没被利用而造成的浪费。
205、带宽控制设备将固定终端的签约带宽与第一带宽之和作为第二带宽，或，带宽控制设备将固定终端的签约带宽、第一带宽以及冗余带宽之和作为第二带宽；
根据各移动终端的签约带宽计算出第一带宽后，带宽控制设备计算固定终端的签约带宽和第一带宽的和，用于作为第二带宽来对固定终端的带宽进行调整。实际运用中，带宽控制设备还可以增加额外的带宽分配给固定终端，即将固定终端的签约带宽、第一带宽以及冗余带宽的和，作为第二带宽来对固定终端的带宽进行调整，以在申请接入的移动终端的数量较多时保证各移动终端的用户体验，其中该冗余带宽可以由带宽控制设备预先设置。
206、带宽控制设备将分配给固定终端的带宽调整为第二带宽，该第二带宽大于固定终端的签约带宽；
在获取到固定终端的签约带宽后，带宽控制设备根据该固定终端的签约带宽对分配给该固定终端的带宽进行调整，使得在有移动终端请求接入时，带宽控制设备给该固定终端分配的带宽从该固定终端的签约带宽调整为第二带宽，其中该第二带宽大于该固定终端的签约带宽。当没有移动终端请求接入时，带宽控制设备将分配给该固定终端的带宽调整回该固定终端的签约带宽。
本实施例中，在移动终端请求从固定终端的家庭网关无线接入互联网时，通过将固定终端的分配带宽动态调整，以使得分配给该固定终端的带宽大于其签约带宽，降低了移动终端用户的接入对使用固定终端的用户的体验的影响；同时，相比长期给固定终端分配大于其签约带宽的带宽，避免了在没有移动终端接入时给运营商接入网络造成的带 宽浪费。
进一步地，带宽控制设备根据各移动终端的签约带宽来计算第一带宽，以将该第一带宽和该固定终端的签约带宽的和或者该第一带宽、该固定终端的签约带宽以及冗余带宽的和作为第二带宽分配给固定终端，能够根据申请接入的移动终端的数量以及签约带宽来动态调整当前分配给固定终端的带宽，以在保证固定终端和各移动终端的用户体验的前提下避免了带宽浪费。
上面实施例中，当有移动终端请求接入时，带宽控制设备分配给固定终端的带宽大于该固定终端的签约带宽以供该固定终端和移动终端使用；那么，各移动终端实际使用的资源可能会大于运营商与其签约的资源，即可能会侵占固定终端或其他移动终端的带宽，影响固定终端或者其他移动终端的用户体验。因此，可选地，上面实施例中的宽带控制方法还包括：
207、带宽控制设备控制各移动终端中的每个移动终端允许使用的带宽为该移动终端的签约带宽；或，带宽控制设备控制各移动终端允许使用的带宽之和为第二带宽与该固定终端的签约带宽的差；
在移动终端请求通过固定终端的家庭网关接入互联网时，根据移动终端与运营商签有的协议，运营商为该移动终端分配其签约带宽。但是，各移动终端在通过固定终端的家庭网关接入互联网时，各移动终端能够使用的资源为运营商为固定终端所分配的带宽，即第二带宽。因此，带宽控制设备对每个移动终端进行限速，使得每个移动终端能够使用的带宽为该移动终端的签约带宽。或者，带宽控制设备也可以不对每个移动终端进行限速，而是对所有移动终端所使用的总带宽进行限速，使得所有移动终端一起所能够使用的总带宽为第二带宽与该固定终端的签约带宽的差，也即所有移动终端一起所能够使用的总带宽为第一带宽，或者所有移动终端一起所能够使用的总带宽为第一带宽与冗余带宽的和。
这样，能够避免各移动终端会侵占带宽控制设备原本为固定终端所分配的签约带宽，避免移动终端对固定终端的用户体验造成影响。
该实施例中，带宽控制设备需要分别获取固定终端和各移动终端的签约带宽，实际运用中，有多种方法来获取该固定终端的签约带宽和各移动终端的签约带宽，下面对本发明实施例中带宽控制方法进行描述。
请参阅图3，本发明的另一个实施例中带宽控制方法包括：
301、带宽控制设备获取移动终端的接入请求，所述接入请求用于指示所述移动终 端请求通过固定终端的家庭网关接入互联网；
本实施例中，该带宽控制设备可以是运营商用于控制带宽的设备。固定终端的家庭网关增加有运营商公众Wi-Fi热点，即该家庭网关可以将移动用户的Wi-Fi数据通过固定宽带接入网回传至运营商Wi-Fi分流网关，再通过该运营商Wi-Fi分流网关发送至互联网，以使得移动终端能够通过固定终端的家庭网关接入互联网。在移动终端需要接入互联网时，该移动终端发送接入请求至带宽控制设备，用于请求通过该固定终端的家庭网关接入互联网；带宽控制设备获取该移动终端的接入请求。其中，请求通过该固定终端的家庭网关进入互联网的移动终端的数量可以为一个或者至少两个。
具体举例来说，移动终端在进入固定终端的家庭网关的公众Wi-Fi热点覆盖区域时，向带宽控制设备发送可扩展身份验证协议(Extensible Authentication Protocol,EAP)报文，该EAP报文用于网络接入认证。由于EAP报文为现有技术，在此不做赘述。
带宽控制设备针对该移动终端触发认证请求报文，并将认证标识(例如该移动终端的媒体接入控制MAC地址)携带在该认证请求报文中发送给该移动终端，其中该认证请求报文包含EAP报文。该移动终端回复认证响应报文给该宽带控制设备。该认证响应报文携带该认证标识和该EAP报文。该带宽控制设备接收该认证响应报文。
当然，上述只是对移动终端和带宽控制设备之间的一些交互流程进行举例描述，并不作限制。
302、带宽控制设备封装并发送接入请求报文至服务器；
带宽控制设备将接入请求报文发送至服务器，以向服务器获取固定终端和各移动终端的签约带宽。具体地，该服务器可以是拨号用户远程认证服务(Remote AuthenticationDial In User Service，RADIUS)服务器。当然，实际运用中，该服务器也可以是其他策略控制服务器，在此不作限制。
举例来说，当本实施例中提到的服务器是RADIUS服务器时，带宽控制设备将获取到的认证响应报文采用EAP over RADIUS模式封装进RADIUS接入请求报文，并携带必要的RADIUS属性，如呼叫站点标识和网络接入IP属性值(即固定终端的家庭网关的宽带连接地址)；然后将该RADIUS接入请求报文发送至指定的RADIUS服务器地址。该RADIUS服务器接收并解析该RADIUS接入请求报文后，生成密钥询问(Key Inquirement)报文并将该密钥询问报文封装进RADIUS接入询问(Request)报文，该RADIUS服务器将该RADIUS接入询问报文发送给带宽控制设备。带宽控制设备接收到该RADIUS接入询问报文后，提取该密钥询问(Key Inquirement)报文并将该密钥询问报文封装成EAP询问(Request) 报文发送至该移动终端。在带宽控制设备接收到来自该移动终端对该EAP询问报文的EAP响应报文后，将该EAP响应报文采用EAP over RADIUS模式，并携带其他RADIUS属性封装进RADIUS接入请求报文，发送至RADIUS服务器。
当然，上述只是对移动终端、带宽控制设备和服务器三者之间的一些交互流程进行举例描述，并不作限制。
303、带宽控制设备接收并解析来自服务器的接入许可报文，其中所述接入许可报文中包含所述移动终端的带宽属性，所述移动终端的带宽属性用于指示所述移动终端的签约带宽；
服务器认证移动终端成功后，根据该移动终端的签约信息获取该移动终端的签约带宽，并将该移动终端的签约带宽值封装在接入许可报文的带宽属性中，发送该接入许可报文至带宽控制设备。带宽控制设备接收并解析该接入许可报文，解析该接入许可报文的带宽属性获得该移动终端的签约带宽值。
具体举例来说，服务器认证移动终端成功后，在Radius中封装EAP报文，并根据移动终端的签约信息使用Offload_Guest_UP_Rate属性和Offload_Guest_down_Rate属性分别携带该移动终端的上下行签约带宽，将Offload_Guest_UP_Rate属性和Offload_Guest_down_Rate属性封装到RADIUS接入许可报文。带宽控制设备接收到该RADIUS接入许可报文后，解析并提取其中的各属性值。
当然，上述描述仅为举例，并不作限制。
304、带宽控制设备根据所述移动终端的签约带宽计算第一带宽；
为了保证固定终端的用户体验，避免移动终端的签约带宽较大或者移动终端的数量较多而导致移动终端过多地占用固定终端的宽带连接，并保证移动终端的用户体验，带宽控制设备在对分配给固定终端的带宽进行调整时，需结合各移动终端的签约带宽来计算第一带宽，然后再根据该第一带宽和固定终端的签约带宽来计算第二带宽。
带宽控制设备根据各移动终端的签约带宽来计算第一带宽的方法有多种。具体举例来说，带宽控制设备选取各移动终端的签约带宽中数值最大的签约带宽作为第一带宽；或者，带宽控制设备将各移动终端的签约带宽的加权值作为第一带宽。当然，以上方法仅为举例，并不作限制。
其中，带宽控制设备将各移动终端的签约带宽的加权值作为第一带宽的方法也有多种。例如，带宽控制设备将各移动终端的签约带宽的和作为第一带宽。实际运用中，由于同一时间内各移动终端所使用的最大带宽并不一定是各移动终端的签约带宽，因此第一带宽也可以不用为各移动终端的签约带宽的和，而是小于各移动终端的签约带宽的 和，也即至少部分移动终端的签约带宽的加权值可以小于1。因此，可以是将各移动终端的签约带宽的平均值作为第一带宽，或者，根据各移动终端的签约带宽来讲各移动终端进行分级，并根据各移动终端的级别来确定其加权值，其中级别越高的移动终端的加权值越大。这样，可以避免运营商的宽带资源没被利用而造成的浪费。
305、带宽控制设备获取固定终端的签约带宽；
带宽控制设备根据固定终端与运营商所签有的协议来查找运营商为该固定终端的家庭网关所分配的签约带宽。
具体举例来说，带宽控制设备在解析RADIUS接入许可报文时，获取移动终端所寄宿的固定终端，并通过查找宽带接入用户信息表来获取该固定终端的签约带宽，然后将该固定终端的上下行签约带宽值分别记入Offload_Host_UP_Rate属性和Offload_Host_Down_Rate属性，连同原有RADIUS属性，重新封装为RADIUS接入许可报文。
实际运用中，RADIUS接入许可报文有多种格式。例如，该RADIUS接入许可报文的属性报文类型编码为26，能力报文长度为可变，设备商标识为设备商的网络管理编码，而子属性编码可以由设备商规划定义。具体举例来说，Offload_Host_UP_Rate属性类型值为251，Offload_Host_Down_Rate属性类型值为252，Offload_Guest_UP_Rate属性类型值为253，Offload_Guest_Down_Rate属性类型值为254。子属性长度为16位，带宽值为可变的，带宽单位为Kbps。这样，RADIUS属性使用RADIUS属性类型终端设备商类型，能够方便设备商自行定义，而通过设备商定义类型值可以区分Offload_Host_UP_Rate属性、Offload_Host_Down_Rate属性、Offload_Guest_UP_Rate属性和Offload_Guest_Down_Rate属性这四种属性。
306、带宽控制设备将固定终端的签约带宽与第一带宽之和作为第二带宽，或，带宽控制设备将固定终端的签约带宽、第一带宽以及冗余带宽之和作为第二带宽；
根据各移动终端的签约带宽计算出第一带宽后，带宽控制设备计算固定终端的签约带宽和第一带宽的和，用于作为第二带宽来对固定终端的带宽进行调整。实际运用中，带宽控制设备还可以增加额外的带宽分配给固定终端，即计算固定终端的签约带宽、第一带宽以及冗余带宽的和，用于作为第二带宽来对固定终端的带宽进行调整，这样，在申请接入的移动终端的数量较多时，各移动终端的用户体验可以得到保障，其中该冗余带宽可以由带宽控制设备预先设置。
307、带宽控制设备将分配给固定终端的带宽调整为第二带宽，该第二带宽大于该固定终端的签约带宽；
在有移动终端请求接入时，在获取到固定终端的签约带宽后，带宽控制设备根据该固定终端的签约带宽对分配给该固定终端的带宽进行调整，带宽控制设备给该固定终端分配的带宽从该固定终端的签约带宽调整为第二带宽，其中该第二带宽大于该固定终端的签约带宽。当没有移动终端请求接入时，带宽控制设备将分配给该固定终端的带宽调整回该固定终端的签约带宽。
本实施例中，在移动终端请求从固定终端的家庭网关无线接入互联网时，通过将固定终端的分配带宽动态调整，以使得分配给该固定终端的带宽大于该固定终端的签约带宽，降低了移动终端用户的接入对使用固定终端的用户的体验的影响；并且，相比长期给固定终端分配大于其签约带宽的带宽，避免了在没有移动终端接入时给运营商接入网络造成的带宽浪费。
为便于理解，下面以一个实际应用场景对本实施例带宽控制方法进行描述。
移动终端在进入固定终端的家庭网关的公众Wi-Fi热点覆盖区域时，发送可扩展身份验证协议(Extensible Authentication Protocol,EAP)报文，该EAP报文用于网络接入认证。家庭网关针对新接入用户，触发认证请求报文，并将认证标识(例如终端MAC地址)携带在该认证请求报文中发送给移动终端，其中该认证请求报文包含EAP报文。移动终端向家庭网关回复认证响应报文，该认证响应报文携带该认证标识，其中该认证响应报文包括该EAP报文。
家庭网关采用EAP over RADIUS模式将移动终端发送的认证响应报文封装进RADIUS接入请求报文，该RADIUS报文还包括一些RADIUS属性，如呼叫站点标识和网络接入IP属性值(即固定终端的家庭网关的宽带连接地址)。该RADIUS报文以使用该家庭网关的固定终端的IP地址作为源地址、指定的RADIUS服务器地址为目的地址发送该RADIUS接入请求报文。
宽带接入网关解析收到的RADIUS接入请求报文，记录呼叫站点标识属性值和网络接入IP属性值(即家庭网关的宽带连接地址)，然后重新封装接入请求报文的源地址、目的地址，其中该源地址为该宽带接入网关的IP地址，目的地址为指定的RADIUS服务器地址，并向Wi-Fi分流网关中转该RADIUS接入请求报文。
Wi-Fi分流网关解析该RADIUS接入请求报文后，记录呼叫站点标识属性值和网络接入IP属性值，然后重新封装该RADIUS接入请求报文的源地址、目的地址，其中该源地址为该Wi-Fi分流网关的IP地址，目的地址为指定的RADIUS服务器地址，并向该RADIUS服务器中转该RADIUS接入请求报文。
该RADIUS服务器接收并解析该RADIUS接入请求报文，从EAP报文的加密算法列表 中选择自己支持的一组加密算法、服务器产生的随机数、证书(包含服务器的名称和公钥)、证书请求形成密钥(Key Inquirement)询问报文，并封装在该RADIUS接入询问(Request)报文中，发送给Wi-Fi分流网关。
Wi-Fi分流网关中继该RADIUS接入询问报文给宽带接入网关，然后宽带接入网关中继该RADIUS接入询问报文给家庭网关。家庭网关把该RADIUS接入询问报文中的密钥询问(Key Inquirement)报文提取出来，封装成EAP询问报文发送给移动终端。
移动终端收到EAP询问报文后，提取服务器证书中的公钥，并产生一个随机密码串，并使用服务器的公钥对其进行加密，最后将加密的信息封装成EAP响应报文发送给家庭网关。
家庭网关将EAP接入响应报文采用EAP over RADIUS模式封装进RADIUS接入请求报文，然后发送给宽带接入网关。宽带接入网关中继该RADIUS接入请求报文给Wi-Fi分流网关，然后Wi-Fi分流网关中继该RADIUS接入请求报文给RADIUS服务器。
RADIUS服务器认证客户端成功后，在Radius中封装EAP报文，并根据该客户端的签约信息，获取该移动终端的签约带宽，使用Offload_Guest_UP_Rate属性和Offload_Guest_Down_Rate属性分别携带上下行带宽，封装Radius接入许可报文，发送给Wi-Fi分流网关。
Wi-Fi分流网关解析RADIUS接入许可报文，提取其中的RADIUS属性，记录呼叫站点标识(即移动终端媒体接入控制MAC地址)、Offload_Guest_UP_Rate属性值和Offload_Guest_Down_Rate属性值，生成Wi-Fi分流用户信息表。然后，Wi-Fi分流网关将RADIUS接入许可报文中继给宽带接入网关。
宽带接入网关解析RADIUS接入许可报文，提取Offload_Guest_UP_Rate属性值和Offload_Guest_Down_Rate属性值，并获取该移动终端所寄宿的固定终端的IP地址。宽带接入网关通过查找宽带接入用户信息表，获取该固定终端的签约带宽信息，并将该固定终端的上下行签约带宽值分别记入Offload_Host_UP_Rate属性和Offload_Host_Down_Rate属性，连同原有RADIUS属性，重新封装RADIUS接入许可报文，并发送给家庭网关。宽带接入网关在流量管理中为该固定终端分配的带宽调整为固定终端的签约带宽和移动终端的签约带宽之和。
家庭网关解析RADIUS接入许可报文，通过呼叫站点标识获取接入移动终端的MAC地址，通过Offload_Guest_UP_Rate属性值和Offload_Guest_down_Rate属性值获取该移动终端用户的签约带宽，并记录这些属性，生成移动终端用户信息，且在流量管理中为该移动终端分配相应的签约带宽。家庭网关还通过Offload_Host_UP_Rate属性值和 Offload_Host_Down_Rate属性值获取固定终端的签约带宽，生成固定终端用户信息，并在流量管理中为该移动用户分配该固定终端的签约带宽和移动终端的签约带宽之和。最后，家庭网关提取EAP报文，向移动终端发送认证成功报文。
移动终端收到认证成功报文，接入成功，启动IP地址配置，发送DHCP请求报文给家庭网关。家庭网关收到该DHCP请求报文后，将收到的DHCP请求报文封装为Ethernetover GRE报文，发送给WiFi分流网关。Wi-Fi分流网关为该移动终端分配IP地址，并将该IP地址记录到Wi-Fi分流用户信息表，发送DHCP响应报文给该移动终端。
移动终端获取IP地址成功后，可以正常访问网络。在家庭网关上，家庭网关分别对Wi-Fi分流流量和固定终端用户流量进行基于类的加权公平排队(Weighted Fair Queuing，WFQ)调度，各自分配带宽得到保证。在宽带接入网关上，为固定终端分配的带宽经过动态调整后，可以保证移动终端和固定终端的总分配带宽。

进一步地，带宽控制设备根据各移动终端的签约带宽来计算第一带宽，以将该第一带宽和该固定终端的签约带宽的和或者该第一带宽、该固定终端的签约带宽以及冗余带宽的和作为第二带宽分配给固定终端，能够根据申请接入的移动终端的数量以及签约带宽来动态调整当前分配给固定终端的带宽，以在保证固定终端和各移动终端的用户体验的前提下避免了带宽浪费。
