WiMAX网络是一种非 3GPP网络,而目前非 3GPP网络与 3GPP***构 架演进(System Architecture Evolution, 筒称 "SAE" ) 网络的互通构架如图 3和图 4所示。图 3为非漫游情况下的非 3GPP网络与 SAE网络的互通构架, 图 4为漫游情况下的非 3GPP网络与 SAE网络的互通构架。 其中, SAE网络 是 3GPP标准组织定义的 Release 8版本的网络体系结构, 它允许非 3GPP网 络接入到 3GPP SAE网络中,并定义了可信任的非 3GPP IP接入网与 SAE网 络的连接体系结构。
其中, 涉及的功能实体有: 网关(Gateway, 筒称 "GW" ) 、 3GPP AAA 服务器、 归属签约用户服务器 (Home Subscriber Server, 筒称 "HSS" ) 、 PCRF, 用户终端设备(User Equipment, 筒称 "UE" )即上文中的移动终端。 其中, SAE网络的网关, 有两种不同的逻辑上的 SAE网关, 分别为 SAE服 务网关 ( Serving GW ) 和分组数据网络网关 ( PDN GW ) 。

然而, 本发明的发明人发现, 根据目前的方案, 移动终端可能无法顺利 地通过非 3GPP网络接入 3GPP网络。 这是因为, 3GPP网络中的 AAA服务 器能够满足 3GPP网络的特性, 但未必能够满足非 3GPP网络的特性, 因此, 可能会导致移动终端无法顺利地通过非 3GPP网络接入 3GPP网络的问题。 发明内容
本发明实施方式要解决的技术问题是提供一种无线通信***、装置及无 线通信方法, 使得移动终端能够通过非 3GPP网络顺利接入 3GPP网络。

下面将结合附图对本发明的实施方式作进一步地详细描述。
本发明的第一实施方式涉及一种通信***, 包含 3GPP 网络和非 3GPP 网络,在本实施方式中 3GPP网络以 SAE网络为例,非 3GPP网络以 WiMAX 网络为例来说明。
图 5是本发明第一实施方式的无线通信***结构示意图。 该非 3GPP网 络将移动终端通过本网络的连接服务网 CSN接入该 3GPP网络, 也就是说, 对于移动终端而言, 该移动终端附着的接入网和核心网均为非 3GPP网络, 接入的 3GPP网络为该移动终端用户的家乡 3GPP网络。
具体地说, 如图 5所示, 接入的 3GPP网络为 SAE网络的 PLMN, 在该 PLMN中包含 3GPP 网络的第一 AAA服务器, 用于为移动终端提供认证、 授权和计费功能。 WiMAX网络的 CSN中包含 WiMAX网络的第二 AAA服 务器, 用于转发该 3GPP网络的第一 AAA服务器与 WiMAX ASN之间的通 信消息, 并协助该第一 AAA服务器完成该移动终端的认证、 授权和计费功 能。 也就是说, 如果 3GPP网络中的第一 AAA服务器不能完全满足 WiMAX 网络需求时, WiMAX网络的第二 AAA服务器必须负责完成前者不能完成的 AAA功能, 包含但不限于以下之一或其任意组合: 移动 IP协议密钥生成功 能、 识别鉴权模式功能、 设备认证功能、 鉴权认证加密密钥的生成分发功能。 WiMAX 网络的第二 AAA服务器通过 Wd*接口转发该 3GPP网络中的第一 AAA服务器与 WiMAX ASN之间的通信消息, 如与鉴权相关的消息。 PLMN 网络中还包含移动终端的 HA, 该 HA用于将该移动终端接入 IP业务, 使得 移动终端的用户能够通过 3GPP网络接入到分组数据网络 PDN,使用 IP业务。
值得一提的是,在用户或业务鉴权授权过程中, 3GPP网络中的第一 AAA 服务器可能与签约信息数据库(如 HSS )交互, 来获取用户或业务相关信息。 第一 AAA服务器与签约信息数据库可能在同一物理实体实现, 此时他们之 间通过内部消息通信。
在 SAE网络的 PLMN和 WiMAX网络的 CSN中还分别包含 PCRF。 由 于在本实施方式中, 移动终端是通过 WiMAX网络的 CSN接入 SAE网络的 PLMN中的, 因此, 对该移动终端而言, 该 WiMAX网络的 CSN可视为该移 动终端用户的拜访地网络, 也就是说, CSN中的 PCRF为 V PCRF (拜访地 PCRF ) , PLMN中的 PCRF为 h PCRF (家乡 PCRF ) 。 该 h PCRF用于策略 决策生成 PCC规则, 并通过 S9接口发给 CSN中的 PCRF (即 v PCRF )。 其 中, PCRF可能是一个单独的实体, 可能与 AAA服务器在一个实体中实现, 也可能与别的实体在一起实现。
在 WiMAX网络的 CSN中还包含策略分发功能实体(即 PDF ) , 用于将 生成的 PCC规则分发给各 PCC策略执行实体, 如 WiMAX网络的 ASN和该 移动终端的 HA, 该策略分发功能实体从 V PCRF处接收生成的 PCC规则。 具体地说, 该 V PCRF通过 S9接口从 h PCRF接收生成的 PCC规则, 并将该 PCC规则直接转发给该 PDF, 或者, 该 V PCRF在通过 S9接口从 h PCRF接 收到生成的 PCC规则后, 根据本地网络策略和 /或网络签约策略对该 PCC规 则做相应的修改,将修改后的 PCC规则发送给该 PDF。由 PDF将收到的 PCC 规则分发给各 PCC策略执行实体, 保证了各 PCC策略执行实体 (如 ASN、 HA、 3GPP网络中的 PDN GW与服务网关等)能够顺利地对该移动终端进行 服务质量 (Quality of Service, 筒称 "QoS" ) 策略控制和计费。 其中, PDF 可以独立实现, 或与所在网络中的 PCRF—起实现 (此时即由 PCRF直接下 发 PCC 规则到 PCC 策略执行实体) , 或在 ASN-GW 中实现 (此时即由 ASN-GW完成分发) , 或与 HA—起实现 (此时即由 HA完成分发) 。
当本实施方式中的路由为家乡路由, 则 HA分配在 PLMN中 (如图 5所 示) , PCC规则由 PLMN中的 h PCRF生成, 通过 CSN中的 v PCRF发送到 CSN中的 PDF, 再由该 PDF发送给 ASN和 HA。 需要说明的是, 由于 HA 在 PLMN中,因此在实际应用中, h PCRF生成的 PCC规则也可以通过 PLMN 网络中的策略分发功能实体 PDF发送给该 HA。 HA可以位于 PLMN中的 PDN GW, 则本实施方式的***结构则如图 6所示, 该移动终端通过该 PDN GW 接入 IP业务。 另外, 需要说明的是, 如果 HA不作为 PCC策略执行实体, 贝' J PDF无需将 PCC规则发送给该 HA。 不难发现, 在本实施方式中, 即使 3GPP网络中的第一 AAA服务器不能满足非 3GPP网络的特性, 也能通过非 3GPP网络的第二 AAA服务器完成 3GPP网络中的第一 AAA服务器不能满 足的功能。 从而保证了移动终端能够通过非 3GPP网络顺利接入该 3GPP网 络, 实现了更高的效率和效益。
本发明的第二实施方式与第一实施方式大致相同, 其区别在于, 在第一 实施方式中, 使用家乡路由, HA分配在 PLMN中。 图 7是本发明第二实施 方式的无线通信***结构示意图。 如图 7所示, 在本实施方式中, 使用拜访 地路由, HA分配在 WiMAX网络的 CSN中。 PCC规则由 PLMN中的 h PCRF 生成,通过 CSN中的 V PCRF发送到 CSN中的 PDF,再由该 PDF发送给 ASN 和 HA。 图 8是本发明第三实施方式的无线通信***结构示意图。 本发明的第三 实施方式与第一实施方式大致相同, 其区别在于, 在第一实施方式中, 未使 用层次化移动管理将该移动终端接入网络; 而在本实施方式中, 使用了层次 化移动管理, 如层次化移动 IP协议 ( Hiearachical MIP, 筒称 "HMIP" ) 将 该移动终端接入网络。
因此, WiMAX 网络原有的 HA 可作为本地移动代理 (Local Mobility Agent, 筒称 "LMA" ) , 实现本地移动锚点的功能, 用于管理本地移动的 锚定。 3GPP网络中的第一 AAA服务器和 WiMAX网络中的第二 AAA服务 器中至少一个 AAA服务器还需要生成和下发 HMIP密钥到 HA和 LMA。 另 夕卜, PCC规则由 PLMN中的 h PCRF生成, 通过 CSN中的 v PCRF发送到 CSN中的 PDF后, 该 PDF还需要将收到的 PCC规则发送给该 LMA, 如图 8 所示。
该 LMA可以位于 CSN内的 WiMAX HA中, 则本实施方式的***结构 如图 9所示, 其中, 移动终端的 HA仍位于 PLMN中的 PDN GW。
需要说明的是, 在上述第一至第三实施方式中, 均以 WiMAX网络中部 署有 PCC架构为例进行说明, 如果 WiMAX网络中没有部署 PCC架构, 则 仍沿用现有的 WiMAX网络的 QoS和计费框架, PLMN内生成的 PCC规则 下发给 CSN内的策略功能实体(policy function, 筒称 "PF" ) , 由 PF完成 WiMAX网络内的策略计费信息下发, PF可能会根据本地策略对 PCC规则做 相应的爹改。
图 10是本发明第四实施方式的无线通信***结构示意图。本发明的第四 实施方式涉及一种通信***, 包含 3GPP 网络和非 3GPP 网络, 该非 3GPP 网络将移动终端通过本网络的接入服务网 ASN接入该 3GPP网络,接入的该 3GPP 网络为该移动终端用户的家乡 3GPP 网络, 第一 AAA服务器与第二 AAA服务器在同一个物理设备中实现。 也就是说, 对于移动终端而言, 该移 动终端通过非 3GPP网络的 ASN直接接入 3GPP的家乡 3GPP网络, 该第一 AAA服务器与第二 AAA服务器所处的物理设备位于该移动终端用户的家乡 3GPP网络中。
本实施方式中的 3GPP网络为 SAE网络,非 3GPP网络为 WiMAX网络。 具体地说, 如图 10所示, 接入的 3GPP网络为 SAE网络的 PLMN, 在 该 PLMN中包含 3GPP AAA服务器 (即第一 AAA服务器与第二 AAA服务 器的合成) , 用于为移动终端提供认证、 授权和计费功能, 并完成该移动终 端在该 3GPP 网络和非 3GPP 网络中所需的所有相关功能, 即 SAE 网络和 WiMAX网络中与认证、 授权和计费相关的全部功能, 包括但不限于用户和 / 或设备认证、 空口 /设备 /移动 IP密钥生成和分发、计费功能和预置流下发等。 值得一提的是, 在用户或业务鉴权授权过程中, 3GPP AAA服务器可能与签 约信息数据库, 如 HSS交互, 来获取用户或业务相关信息。 3GPP AAA服务 器与签约信息数据库可能在同一物理实体实现, 此时他们之间通过内部消息 通信。
在该 PLMN中还包含 PCRF和策略分发功能实体 (如 PDF ) , 该 PCRF 用于为该移动终端生成 PCC规则, 该策略分发功能实体用于将生成的 PCC 规则分发给各 PCC策略执行实体。 也就是说, PLMN 中的 PCRF将生成的 PCC规则发送给 PDF, 由该 PDF将收到的 PCC规则分发给各 PCC策略执行 实体, 从而保证了各 PCC策略执行实体能够顺利地对该移动终端进行计费。 其中, PCC策略执行实体可以是以下之一或其任意组合: ASN、 该移动终端 的 HA、 PDN GW、 服务网关, 该 HA需要能够满足 WiMAX网络特性, 和 / 或执行 PLMN网络的策略计费, 该移动终端通过该 HA接入 IP业务, 使得 移动终端的用户能够使用 IP业务。另外,为了能够将在 PLMN中生成的 PCC 规则发送到 WiMAX的 ASN中, PLMN网络与 ASN之间的接口需要提供用 于传递 PCC规则的能力。
HA和 PDF可以在 PLMN的 PDN GW中实现时,该移动终端通过该 PDN
GW接入 IP业务, PDN GW与 ASN之间的 S2a接口除了支持移动 IP协议外, 还需要支持将 PCC的规则下发到 ASN网络中的对应实体上, 如图 11所示。 由于在本实施方式中, PLMN网络中的 3GPP AAA服务器是将第一 AAA 服务器和第二 AAA服务器合成而成, 因此能够满足 WiMAX网络的特性, 从而保证了移动终端能够通过 WiMAX网络的 ASN顺利接入该 3GPP网络, 实现了更高的效率和效益。
图 12是本发明第五实施方式的无线通信***结构示意图。本发明的第五 实施方式涉及一种通信***, 本实施方式与第四实施方式大致相同, 其区别 在于, 在第四实施方式中, 未使用层次化移动管理将该移动终端接入网络; 而在本实施方式中, 使用了层次化移动管理, 如 HMIP将该移动终端接入网 络。
因此, 如图 12所示, 在 PLMN中还包含本地移动锚点, 在 HMIP中称 为 LMA, 用于管理本地移动的锚定。 3GPP AAA服务器还需要生成 HMIP密 钥。 另外, PCC规则由 PCRF生成, 发送给 PDF后, 该 PDF还需要将收到 的 PCC规则发送给该 LMA。
该 LMA可以位于 PLMN内的月良务网关中, 则本实施方式的***结构如 图 13所示, 其中, 移动终端的 HA和 PDF仍位于 PLMN中的 PDN GW, 移 动终端通过 PDN GW接入到 IP业务中。
图 14是本发明第六实施方式的无线通信***结构示意图。本发明的第六 实施方式涉及一种通信***, 本实施方式与第四实施方式大致相同, 其区别 在于,在第四实施方式中,移动终端通过 WiMAX网络的 ASN直接接入该移 动终端用户的家乡 3GPP网络, 第一 AAA服务器与第二 AAA服务器在同一 个物理设备中实现; 而在本实施方式中, 移动终端通过 WiMAX网络的 ASN 接入该移动终端用户的拜访地 3GPP网络, 再通过该拜访地 3GPP网络接入 该移动终端的家乡 3GPP网络,第一 AAA服务器位于该移动终端用户的家乡 3GPP网络, 第二 AAA服务器位于该移动终端用户的拜访地 3GPP网络, 该 移动终端接入的拜访地 3GPP网络和家乡 3GPP网络均为 3GPP的 PLMN。 具体地说, 如图 14所示, 移动终端通过 ASN、 拜访地 PLMN网络接入 到家乡 PLMN。该家乡 PLMN网络中包含的 3GPP网络的第一 AAA服务器, 用于为移动终端提供认证、 授权和计费功能, 并完成该移动终端在该 3GPP 网络和非 3GPP网络中所需的所有相关功能, 即 SAE网络和 WiMAX网络中 与认证、 授权和计费相关的全部功能
该拜访地 PLMN网络中包含的第二 AAA服务器, 用于转发家乡 PLMN 网络中的第一 AAA月良务器与该 WiMAX网络的 ASN之间的通信消息,因此, 该拜访地 PLMN网络中的第二 AAA服务器的作用即为 AAA代理服务器。
在家乡 PLMN 网络和拜访地 PLMN 网络中还分别包含 PCRF (即家乡 PCRF ( h PCRF )和拜访地 PCRF ( v PCRF;) ) 。 该 h PCRF用于为该移动终 端生成 PCC规则, 并通过 S9接口发给 v PCRF。
在拜访地 PLMN网络中还需包含策略分发功能实体(即 PDF ) , 用于将 生成的 PCC规则分发给各 PCC策略执行实体, 如 WiMAX网络的 ASN和该 移动终端的 HA, 该策略分发功能实体从 V PCRF处接收生成的 PCC规则。 具体地说, 该 V PCRF通过 S9接口从 h PCRF接收生成的 PCC规则, 并将该 PCC规则直接转发给该 PDF, 或者, 该 V PCRF在通过 S9接口从 h PCRF接 收到生成的 PCC规则后, 根据本地网络策略和 /或网络签约策略对该 PCC规 则做相应的修改, 将修改后的 PCC规则发送给该 PDF。 由该 PDF将收到的 PCC规则分发给各 PCC策略执行实体, 保证了各 PCC策略执行实体能够顺 利地对该移动终端进行计费。考虑到 HA可能分配在家乡网络或拜访地网络, 负责分发给 HA的策略分发功能实体也可位于家乡网络, 该策略分发功能实 体从 h PCRF接收 PCC规则, 然后将 PCC规则信息下发给 HA。 值得一提的 是, 移动终端通过该 HA接入 IP业务, 使得移动终端的用户能够使用 IP业 务。
当本实施方式中的路由为家乡路由, 则 HA分配在家乡 PLMN中, 本实 施方式中的 HA与家乡 3GPP网络的 PDF均在家乡 PLMN网络的 PDN GW 中实现, 如图 14所示, PCC规则由家乡 PLMN网络中的 h PCRF生成, 通 过拜访地 PLMN网络中的 V PCRF发送到拜访地 PLMN网络中的 v PDF, 再 由该 V PDF发送给 HA (即图中的 h PDN GW ) ; 或者, 由 h PCRF将 PCC 规则通过家乡网络的 PDF下发给 HA,进一步,家乡网络的 PDF可在 PDN GW 实现,则此时为 h PCRF直接将 PCC规则下发给家乡 PLMN网络的 PDN GW。 另外, 需要说明的是, 如果 HA不作为 PCC策略执行实体, 则无需将 PCC 规则发送给该 HA。
本实施方式中拜访地 PLMN网络的 V PDF,也可以与 V PDN GW和 /或 v Serving GW (拜访地 PLMN网络的服务网关) 在一个实体中, 或单独存在。 如果该 V PDF与 V PDN GW和 /或 v Serving GW在一个实体中,并且该 v PDF 负责向 HA分发 PCC规则信息, 则为了能够将生成的 PCC规则从家乡网络 中的 GW发送到拜访地网络中的 GW , 则家乡网络中的 GW和拜访地网络中 的 GW之间的 S8b接口需要提供用于传递 PCC规则的能力。
图 15是本发明第七实施方式的无线通信***结构示意图。本发明的第七 实施方式涉及一种通信***, 本实施方式与第六实施方式大致相同, 其区别 在于, 在第六实施方式中, 使用的路由为家乡路由, HA分配在家乡 PLMN 中; 而在本实施方式中, 使用的路由为拜访地路由, 因此, 该 HA分配在拜 访地 PLMN网络中,如将该 HA分配在拜访地 PLMN网络中的 v PDN GW中, 如图 15所示。 PCC规则由 PLMN中的 h PCRF生成, 通过拜访地 PLMN网 络中的 V PCRF发送到拜访地 PLMN网络中的 PDF, 该 PDF也在 v PDN GW 中实现, 再由该 PDF发送给 ASN和 HA。 由于此时 PDF和 HA在同一个实 体实现, 它们之间通过内部消息通信。
本发明的第八实施方式涉及一种通信***, 本实施方式与第六实施方式 大致相同, 其区别在于, 在第六实施方式中, 未使用层次化移动管理将该移 动终端接入网络; 而在本实施方式中, 使用了层次化移动管理, 如 HMIP, 将该移动终端接入网络。 因此, 在拜访地 PLMN 网络中还包含本地移动锚点, 在 HMIP 中称为 LMA, 用于管理本地移动的锚定。 3GPP AAA服务器和 /或 3GPP AAA代理 服务器还需要生成 HMIP 密钥。 另外, PCC规则由家乡 PLMN 网络中的 h PCRF生成, 通过拜访地 PLMN网络中的 V PCRF发送到拜访地 PLMN网络 中的 PDF后, 该 PDF还需要将收到的 PCC规则发送给该 LMA。
该 LMA可以位于拜访地 PLMN内的 PDN GW中, HA仍位于家乡 PLMN 内的 PDN GW中,拜访地 PLMN内的 PDF位于拜访地 PLMN网络中的 PDN GW, 则本实施方式的***结构如图 16所示。
该 LMA 也可以位于拜访地 PLMN 内的服务网关中, HA 仍位于家乡 PLMN内的 PDN GW中, 拜访地 PLMN内的 PDF位于拜访地 PLMN网络中 的服务网关, 则本实施方式的***结构如图 17所示。
图 18是本发明第九实施方式的通信***结构示意图。本发明的第九实施 方式涉及一种通信***, 本实施方式与第八实施方式大致相同,其区别在于, 在第八实施方式中, 使用的路由为家乡路由, HA分配在家乡 PLMN网络中, 而在本实施方式中, 使用的路由为拜访地路由, HA分配在拜访地 PLMN网 络中。
如图 18所示, HA位于拜访地 PLMN网络中的 v PDN GW, LMA位于 拜访地 PLMN网络中的 v Serving GW, PDF位于拜访地 PLMN网络中的 PDN GW和 /或拜访地 PLMN网络中的 V Serving GW。 PCC规则由家乡 PLMN网 络中的 h PCRF生成, 通过拜访地 PLMN 网络中的 v PCRF发送到拜访地 PLMN网络中的 V PDF, 再由该 PDF发送给 ASN和 HA。
在上述各实施方式中, 还有以下几点需要说明:
( 1 ) 如果两个实体间需要传输 PCC规则, 如 PDF需要将 PCC规则发 送给 ASN的网关, 则这两个实体间的接口需要提供用于传递 PCC规则的能 力。
( 2 ) 移动终端通过 HA接入的 IP业务, 可以是外部的公共或私有的分 组数据网络, 也可以是运营商内部的分组数据网络, 即运营商部署的各种 IP 业务 ( operator's IP Service ) , 例如交互式多媒体*** ( Interactive Multimedia System, 筒称 "IMS" ) 、 分组交换域流媒体业务( Packet Streaming Service, 筒称 "PSS" ) 等。
( 3 )如果移动终端需要使用多个网络的数据业务, 可采用多 MIP (移动
IP ) 注册的机制, 通过相应的多个 PDN GW接入到多个 IP业务网络中; 此 时要求 WiMAX网络支持多 HA注册。 例如当处于漫游的场景时, 移动终端 既要使用家乡 3GPP网络的数据业务, 也要使用拜访地 3GPP网络的数据业 务, 则可以将该移动终端分别注册到家乡 3GPP网络的 HA (该 HA在 h PDN GW中实现)和拜访地网络的 HA (该 HA可以在 V 服务网关、 v PDN GW或 WiMAX CSN中的 HA中实现) , 采用双 MIP注册的机制。 即等同于移动终 端与多个 IP数据网络通信, 需要与这些 IP数据网络对应的网关接入。 3GPP 和 /或 WiMAX AAA服务器需要为每个注册单独生成、分发和维护 MIP密钥。
( 4 ) 同一 PLMN网络中的月良务网关和 PDN GW可以位于同一个物理实 体上, 此时它们之间通过内部消息进行通信。 SAE网络中的 HA (或 LMA ) 、
PDF可能在同一网关上,此时他们之间使用内部消息通信。 PDF也可与 PCRF 在同一物理实体中实现。
( 5 ) PLMN网络中的网关也具有策略计费执行功能, 当它们接收到 PCC 规则时, 将应用这些规则, 执行 QoS策略控制和计费。
图 19是本发明第十实施方式的无线通信装置结构示意图。本发明的第十 实施方式涉及一种无线通信装置, 在本实施方式中 3GPP网络以 SAE网络为 例, 非 3GPP网络以 WiMAX网络为例来说明。
如图 19所示, 该装置包括第二 AAA服务器, 该第二 AAA服务器用于 转发 3GPP网络中的第一 AAA服务器与非 3GPP网络之间的通信消息,并协 助第一 AAA服务器完成移动终端的认证、 授权和计费功能。
具体地, 接入的 3GPP网络为 SAE网络的 PLMN, 在该 PLMN中包含 3GPP 网络的第一 AAA服务器,用于为移动终端提供认证、授权和计费功能。 WiMAX网络的 CSN中包含 WiMAX网络的第二 AAA服务器, 用于转发该 3GPP网络的第一 AAA服务器与 WiMAX ASN之间的通信消息,并协助该第 一 AAA服务器完成该移动终端的认证、 授权和计费功能。 也就是说, 如果 3GPP网络中的第一 AAA服务器不能完全满足 WiMAX网络需求时, WiMAX 网络的第二 AAA服务器必须负责完成前者不能完成的 AAA功能。 WiMAX 网络的第二 AAA服务器通过 Wd*接口转发该 3GPP网络中的第一 AAA服务 器与 WiMAX ASN之间的通信消息, 如与鉴权相关的消息等。
进一步地, 该第一 AAA 服务器可以位于移动终端的用户的家乡 3GPP 网络中, 同时第二 AAA服务器位于非 3GPP网络中。
第一 AAA服务器也可以位于移动终端的用户的家乡 3GPP网络中,同时 第二 AAA服务器位于移动终端的用户的拜访地 3GPP网络中。
第一 AAA服务器还可以与第二 AAA服务器在同一个物理设备中实现, 该第一 AAA服务器与该第二 AAA服务器还可以位于移动终端的用户的家乡 3GPP网络中。
在本实施方式中,即使 3GPP网络中的第一 AAA服务器不能满足非 3GPP 网络的特性,也能通过非 3GPP网络的第二 AAA服务器完成 3GPP网络中的 第一 AAA 服务器不能满足的功能。 从而保证了移动终端能够通过非 3GPP 网络顺利接入该 3GPP网络, 实现了更高的效率和效益。
本发明的第十一实施方式涉及一种无线通信方法,图 20是本发明第十实 施方式的无线通信方法流程图。
如图 20所示, 在步骤 1910中, 将移动终端通过非 3GPP网络接入 3GPP 网络。 具体地说, 将该移动终端通过非 3GPP网络的核心网接入 3GPP网络, 接入的 3GPP网络为该移动终端的家乡 3GPP网络。 本实施方式中, 非 3GPP 网络以 WiMAX 网络为例进行说明, 因此, 该核心网即为 WiMAX 网络的 CSN。 接着, 进入步骤 1920, 对该移动终端进行认证、授权和计费。 具体地说, 由该 3GPP网络中的第一 AAA服务器对该移动终端进行认证、 授权和计费, 该第一 AAA服务器与非 3GPP网络之间的通信消息,需要通过非 3GPP网络 的 CSN中的第二 AAA服务器转发。 并且, 该第二 AAA服务器协助完成该 移动终端的认证、授权和计费功能。由此可见,即使 3GPP网络中的第一 AAA 服务器不能满足非 3GPP网络的特性,也能通过非 3GPP网络的第二 AAA服 务器完成 3GPP网络中的第一 AAA服务器不能满足的功能。从而保证了移动 终端能够通过非 3GPP网络顺利接入该 3GPP网络, 实现了更高的效率和效 益。
接着, 在步骤 1930中, 在 3GPP网络中为该移动终端生成 PCC规则, 并将生成的 PCC规则分发给各 PCC策略执行实体。 具体地说, 由 3GPP网 络中的 PCRF (即 h PCRF ) 为该移动终端生成 PCC规则, 并将生成 PCC规 则发送给 CSN中的 PCRF (即 V PCRF ) , 该 v PCRF可以直接将收到的 PCC 规则发送给 CSN中的策略分发功能实体 (即 v PDF ) ; 该 v PCRF也可以在 收到 PCC规则后, 根据本地网络策略和 /或网络签约策略, 对收到的 PCC规 则做相应的修改, 将修改后的 PCC规则发送给 V PDF。 由 V PDF将收到的 PCC规则分发给各 PCC策略执行实体, 其中, PCC策略执行实体包含以下 之一或其任意组合: 非 3GPP网络的 ASN、 该移动终端的 HA、 3GPP网络的 PDN GW、 服务网关。
需要说明的是, 如果使用家乡路由, 则该移动终端的 HA 分配在家乡
3GPP网络中, V PDF可以将 PCC规则分发给该 HA; 或者, 由 h PCRF通过 h PDF将 PCC规则发送给该 HA。如果使用拜访地路由,则该移动终端的 HA 分配在 CSN中, v PDF需将 PCC规则分发给该 HA。
在本实施方式中, 步骤 1920与步骤 1930并没有明确的先后关系, 并且, 本实施方式中的 3GPP网络为 SAE网络。 另外, 值得一提的是, 本实施方式 中的移动终端通过 HA接入 IP业务, 使得移动终端的用户能够使用 IP业务。 本发明的第十二实施方式涉及一种无线通信方法, 本实施方式与第十一 实施方式大致相同, 其区别在于, 在第十一实施方式中, 未使用层次化移动 管理将该移动终端接入网络; 而在本实施方式中, 使用了层次化移动管理, 如 HMIP将该移动终端接入网络。 因此, 第一 AAA服务器和第二 AAA服务 器中至少一个还需要生成 HMIP密钥。 另外, PCC规则由 h PCRF生成, 并 通过 CSN中的 V PCRF发送到 V PDF后, 该 v PDF还需要将收到的 PCC规 则发送给用于管理本地移动的锚定的 LMA。
本发明的第十三实施方式涉及一种无线通信方法, 本实施方式与第十一 实施方式大致相同, 其区别在于, 在第十一实施方式中, 将移动终端通过非 3GPP网络的核心网接入 3GPP网络; 而在本实施方式中, 将该移动终端通过 非 3GPP网络的接入网接入该移动终端的拜访地 3GPP网络, 再通过该拜访 地 3GPP网络将该移动终端接入家乡 3GPP网络。 同样的, 非 3GPP网络以 WiMAX网络为例进行说明, 因此, 该接入网即为 WiM AX网络的 ASN。
也就是说,由该家乡 3GPP网络中的第一 AAA服务器对该移动终端进行 认证、 授权和计费, 该第一 AAA服务器与非 3GPP网络 ASN之间的通信消 息, 需要通过拜访地 3GPP网络中的第二 AAA服务器转发。
由家乡 3GPP网络中的 PCRF(即 h PCRF )为该移动终端生成 PCC规则, 并将生成 PCC规则发送给拜访地 3GPP网络中的 PCRF (即 v PCRF ) , 该 v PCRF可以直接将收到的 PCC规则发送给拜访地 3GPP网络中的策略分发功 能实体 (即 v PDF ) ; 该 V PCRF也可以在收到 PCC规则后, 根据本地网络 策略和 /或网络签约策略,对收到的 PCC规则做相应的修改,将修改后的 PCC 规则发送给 V PDF。 由 V PDF将收到的 PCC规则分发给各 PCC策略执行实 体, 其中, PCC策略执行实体包含以下之一或其任意组合: 非 3GPP网络的 ASN、 该移动终端的 HA、 3GPP网络的 PDN GW、 服务网关。
类似地, 如果使用家乡路由, 则该移动终端的 HA分配在家乡 3GPP网 络中, V PDF可以将 PCC规则分发给该 HA; 或者, 由 h PCRF通过 h PDF 将 PCC规则发送给该 HA。 如果业务使用拜访地路由, 则该移动终端的 HA 分配在拜访地 3GPP网络中, V PDF需将 PCC规则分发给包含该 HA的各 PCC 策略执行实体。
本发明的第十四实施方式涉及一种无线通信方法, 本实施方式与第十三 实施方式大致相同, 其区别在于, 在第十三实施方式中, 将该移动终端通过 非 3GPP网络的 ASN接入该移动终端的拜访地 3GPP网络, 再通过该拜访地 3GPP网络将该移动终端接入该移动终端的家乡 3GPP网络;而在本实施方式 中,将该移动终端通过非 3GPP网络的 ASN直接接入该移动终端的家乡 3GPP 网络。此时,第一 AAA服务器与第二 AAA服务器在同一个物理设备中实现。
由 3GPP网络中的 PCRF为该移动终端生成 PCC规则, 并将生成的 PCC 规则通过 PDF分发给各 PCC策略执行实体,如非 3GPP网络的 ASN和 /或该 移动终端的 HA。
综上所述, 在本发明的实施方式中, 将移动终端通过非 3GPP网络接入 3GPP网络, 3GPP网络的第一 AAA服务器为移动终端提供认证、 授权和计 费功能, 由第二 AAA服务器转发 3GPP 网络中的第一 AAA服务器与该非 3GPP网络之间的通信消息, 并协助该 3GPP网络中的第一 AAA服务器完成 该移动终端的认证、授权和计费功能。使得即使 3GPP网络中的第一 AAA服 务器不能满足非 3GPP网络的特性,也能通过非 3GPP网络中的第二 AAA服 务器完成 3GPP网络中的第一 AAA服务器不能满足的功能。从而保证了移动 终端能够通过非 3GPP网络顺利接入该 3GPP网络, 实现了更高的效率和效 益。
由 3GPP网络中的 PCRF为移动终端生成 PCC规则, 并通过策略分发功 能实体, 将生成的 PCC规则分发给各 PCC策略执行实体。 保证了各 PCC策 略执行实体(如 ASN、 HA等) 能够顺利地对该移动终端进行计费。
在使用层次化移动管理, 如 HMIP的情况下, 认证、 授权和计费功能还 包含生成相关密钥,如 HMIP密钥,可选的,策略分发功能实体还需要向 LMA 分发 PCC规则。 使得本发明方案具有更为广泛的应用范围。
虽然通过参照本发明的某些优选实施方式, 已经对本发明进行了图示和 描述, 但本领域的普通技术人员应该明白, 可以在形式上和细节上对其作各 种改变, 而不偏离本发明的精神和范围。
