一种用户信息的通知方法及系统 技术领域
本发明涉及移动通信领域, 尤其涉及一种用户信息的通知方法及系统。 背景技术
随着网络技术的发展和用户对业务的需求, 终端逐渐多模化, 可以选 择在不同类型的接入网络接入, 以承载多样性的业务。 不同的网络连接具 有不同的特性和传输能力, 以便能够更好地满足用户对业务多样的需求。 目前, 多模终端可以实现不同类型的无线访问网络之间的无缝连接, 如蜂 窝的通用移动通信系统 ( UMTS , Universal Mobile Telecommunications System ), 增强型数据速率 GSM演进技术( EDGE, Enhanced Data Rate for GSM Evolution ), 通用分组无线服务技术(GPRS , General Packet Radio Service )与 IEEE 802.11中的无线局域网络(WLAN, Wireless Local Area Networks )之间的无缝连接。 WLAN可在小范围的家庭和热点区域提供很 高的数据速率, 而蜂窝网络可以提供更高的灵活性和无处不在的覆盖, 但 数据速率较低; 如果能够结合两者的优点, 用户将从中受益。 在 WLAN访 问点的覆盖范围内,多模终端利用 WLAN进行数据访问和网络电话(VoIP, Voice over Internet Protocol ) 的应用, 同时还能使用重叠的蜂窝网络, 进行 语音呼叫或媒体访问。
目前, 国际标准组织都在进行网络架构标准化的工作, 如第三代合作 伙伴计划 (3GPP, The 3rd Generation Partnership Project )定义移动网络架 构, 其中策略控制和计费单元(PCC, Policy Control and Charging ) 完成移 动网络的资源接纳控制功能, 宽带论坛(BBF, Broadband Forum )定义固 定网络架构, 宽带策略控制框架实体 ( BPCF , Broadband Policy Control Framework ) 完成固定网络的资源接纳控制功能。
当移动网络的用户在 BBF网络接入时, 由于网络的异构性, 在用户的 接入认证和 IP地址分配上, 与普通 BBF用户的接入认证及 IP地址分配存 在一定的差异, 而且为了保证用户业务的服务质量 (QoS , Quality of Service ), PCC与 BPCF需要建立相应的会话, 完成 QoS策略规则的交互。
图 1是现有技术中经由 RG的认证的流程示意图,如图 1所示,在认证 过程中,用户设备 ( UE, User Equipment )将认证报文发送给住宅网关( RG, Residence Gateway ), RG将认证报文进行封装处理后, 将认证报文发送给 BBF认证、授权和计费单元 ( AAA , Authentication Authorization Accounting ); 如果认证通过, BBF AAA 将保存 UE 的介质访问控制地址 ( MAC , Medium/Media Access Control ),并在 IP地址分配阶段, BBF AAA根据 MAC 地址为 UE分配 IP地址。
现有技术中存在的问题是: 在认证过程中, UE将认证报文发送给 RG, RG认证报文进行封装处理后, 发送给 BBF AAA完成用户的认证, 即通过 图 1中的流程完成认证,是不经过宽带网络网关控制设备(BNG, Broadband Network Gatewny ), 图 2是现有技术中为 UE分配 IP地址的流程示意图, 如图 2所示, 在 IP地址分配阶段, 由 BBF AAA根据 MAC地址为 UE分配 IP地址成功后, 因为该 UE是非 BBF用户, 所以对于需要保证 QoS的用户 业务, 需要建立 BPCF与 PCC的会话, 用于传递相应的 QoS策略, 但是 BNG收到 UE的地址请求报文后,无法判断 UE的用户信息,从而使得 BPCF 无法建立与 PCC的会话, 进而不能传递相应的 QoS策略, 无法保证用户业 务的 QoS。 发明内容

步驟 1403 , 收到 UE发送的 EAPoL Start报文后, RG向 UE发送 EAP Identity Request报文, 用于通知 UE上报用户标识; 其中, 用户标识可以为 NAI。
步驟 1404,收到 RG发送的 EAP Identity Request报文后, UE回复 EAP Identity Response报文给 RG , 其中报文中携带 UE的用户标识。
步驟 1405, RG将收到的 EAP Identity Response 4艮文封装到 RADIUS Access Request报文中, 将 RADIUS Access Request报文发送给 BBF AAA。
步驟 1406, BBF AAA根据 RADIUS Access Request才艮文中封装的 EAP Identity Response报文中的 UE的用户标识,将从 RG收到的 RADIUS Access Request 4艮文转发给 Home AAA。
步驟 1407, 收到 BBF AAA发送的 RADIUS Access Request 4艮文后, Home AAA回复 RADIUS Access Response报文给 BBF AAA,其中该报文中 携带 E AP Identity Response报文。
步骤 1408, BBF AAA将收到的 RADIUS Access Response报文转发给
RG。
步驟 1409, RG从收到的 RADIUS Access Response报文中,解封出 ΕΑΡ Identity Request才艮文, 并将该 EAP Identity Request才艮文发送给 UE。
步骤 1410, 收到 RG发送的 EAP Identity Request报文后, UE回复报 文给 RG, 报文中携带 Challenged Password。
步骤 1411 ,收到 UE回复的报文后, RG将解封装后得到的 EAP Identity Response报文封装到 RADIUS Access Request报文中,并发送给 BBF AAA, 其中携带收到的 Challenged Password。
步骤 1412, BBF AAA将收到的 RADIUS Access Request报文转发给
Home AAA。
步骤 1413 , 当请求接入 BBF接入网络的 UE通过认证时, Home AAA 回复 RADIUS Access Accept报文给 BBF AAA; 如果请求接入 BBF接入网 络的 UE没有通过认证,则不回复 RADIUS Access Accept报文给 BBF AAA, 结束流程。
步骤 1414 , BBF AAA转发 RADIUS Access Accept报文给 RG。
步驟 1415, BBF AAA发送用户接入通知报文给 BPCF, 其中携带 UE 的用户标识;这里,用户标识可以为 NAI; UE的用户标识是在 UE接入 BBF 接入网络时的认证过程中, UE发送给 BBF AAA的。
步骤 1415, BPCF收到 BBF AAA发送的用户接入通知报文后, 根据其 中携带的 UE 的用户标识判断是否需要与移动网络的策略控制系统建立会 话, 如果需要, 则 BPCF 向移动网络的策略控制系统发送会话建立 ·^艮文, 其中携带 UE的用户标识; 其中, 移动网络的策略控制系统可以是 3GPP的 PCC。
步驟 1416, RG发送 EAP Success报文给 UE。
