It is based on a wired LAN and enables wireless communication through devices such as a wireless hub (Hub), an Access Point ("AP"), a wireless bridge, a wireless network card, and an antenna. Transmission media shields used in WLANs mainly include microwave and infrared (Infrared) pulses, which convert data packets (packets) into microwave or infrared pulses to provide various functions of the local area network. Any personal computer (PC), with a wireless network card, can access the resources of the local area network through the wireless access point of the WLAN, and even enjoy the resources on the Internet.
无线局域网包括多种不同技术 , 目前应用较为广泛的一个技术标准 是电子和电气工程师协会 ( Institute of Electrical and Electronics Engineers, 简称 "IEEE" )制定的 IEEE 802.11b, 它采用 2.4GHz频段, 最高数据传 输速率可达 11Mbps,使用该频段的还有 IEEE 802. llg和蓝牙(Bluetooth ) 技术, 其中, 802.11g最高数据传输速率可达 54Mbps。 其它新技术诸如 IEEE 802.11a和 ETSI BRAN Hiperian2都使用 5GHz频段, 最高传输速率 也可达到 54Mbps。  Wireless LAN includes a variety of different technologies.

随着 WLAN技术的兴起和发展, WLAN与各种无线移动通信网,诸 如: 全球移动通信*** ( Global System for mobile Communication, 简称 "GSM" ) 码分多址(Code Division Multiple Access, 简称 "CDMA" ) ***、 宽带码分多址 ( Wideband Code Division Multiple Access, 简称 "WCDMA" )***、 时分同步码分多址( Time Division Synchronous Code Division Multiple Access, 简称 "TD-SCDMA" ) ***、 CDMA 2000*** 的互通正成为当前研究的重点。 本发明的适用范围就是这种 WLAN和各 种无线移动通信网组成的互通网絡。 With the rise and development of WLAN technology, WLAN and various wireless mobile communication networks, such as: Global System for mobile communication (Global System for mobile communication, referred to as "GSM") Code Division Multiple Access ("CDMA") system, Wideband Code Division Multiple Access (WCDMA) system, Time Division Synchronous The interoperability of Code Division Multiple Access ("TD-SCDMA") system and CDMA 2000 system is becoming the focus of current research. The scope of application of the present invention is an interworking network of such WLANs and various wireless mobile communication networks.
互通无线局域网(Interworking WLAN, 简称 "I-WLAN" )是 WLAN 和其它无线移动通信网互通而产生的网络。 在第三代合作伙伴项目 ( 3rd Generation Partnership Project, 简称 "3GPP" )标准化组织中, 用户设备 可以通过 WLAN接入网络( WLAN Access Network, 简称 "WLAN AN" ) 与因特网、 企业内部互联网 (Intranet )相连, 还可以经由 WLAN接入网 络与 3GPP***的归属网络或 3GPP***的访问网絡连接,具体地说就是, WLAN用户设备在本地接入时, 经由 WLAN接入网络与 3GPP的归属网 络相连;在漫游时,经由 WLAN接入网絡与 3GPP的访问网络相连, 3GPP 访问网络中的部分实体分别与 3GPP归属网络中的相应实体互连, 比如: 3GPP访问网络中的 3GPP认证授权计费( Authentication Authorization and Accounting, 简称 "AAA" )代理和 3GPP归属网络中的 3GPP AAA服务 器; 3GPP网络中的无线局域网接入网关 (WLAN Access Gateway, 简称 "WAG" ) 与 3GPP网络中的分组数据网关(Packet Data Gateway, 简称 "PDG" )等等。  Interworking WLAN (I-WLAN) is a network generated by interworking between WLAN and other wireless mobile communication networks. In the 3rd Generation Partnership Project (3GPP) standardization organization, user equipment can access the Internet through a WLAN access network (WLAN Access Network, referred to as "WLAN AN") and the Internet, intranet (Intranet) Connected, and may also be connected to the home network of the 3GPP system or the access network of the 3GPP system via the WLAN access network. Specifically, when the WLAN user equipment accesses the local network, it is connected to the home network of the 3GPP through the WLAN access network; When roaming, the WLAN access network is connected to the 3GPP access network, and some entities in the 3GPP access network are respectively interconnected with corresponding entities in the 3GPP home network, for example: 3GPP authentication and authorization charging in the 3GPP access network (Authentication Authorization and Accounting, referred to as "AAA" for proxy and 3GPP AAA server in 3GPP home network; WLAN Access Gateway (WAG) in 3GPP network and Packet Data Gateway in 3GPP network Referred to as "PDG" and so on.
下面结合图 1、图 2介绍非漫游和漫游两种状态下 I-WLAN的基本模 型。 图 1示出了非漫游状态下的基本模型。 WLAN UE ( User Equipment, 用户设备)接入到 WLAN AN, WLAN AN还和 Intemet/Intranet、 3GPP 归属网络相连, UE可以通过 WLAN AN访问 Internet/Intranet或接入 3GPP 归属网络。具体地说, WLAN AN通过 Wa接口和 3GPP AAA服务器连接、 通过 Wn接口和 WAG连接。 在 3GPP归属网络中, 3GPPAAA服务器又 分别和签约定位功能(Subscription Locator Function, 筒称 " SLF" )、 归属 签约用户服务器(Home Subscriber Server, 简称 "HSS" )、 归属位置寄存 器(Home Location Register,简称" HLR" )、离线计费***( Offline Charging System )、 在线计费***( Online Charging System, 简称 "OCS" )、 PDG, WAG相连接。 PDG还一方面和 WAG连接, 一方面和外部网絡连接。 在 UE和 PDG之间可以建立隧道, 有了这个隧道, WLAN AN和 WAG对 UE和 PDG是透明的。 The basic model of I-WLAN in non-roaming and roaming states will be described below with reference to FIG. 1 and FIG. 2. Figure 1 shows the basic model in a non-roaming state. The WLAN UE (User Equipment) is connected to the WLAN AN. The WLAN AN is also connected to the Internet/Intranet and the 3GPP home network. The UE can access the Internet/Intranet or access the 3GPP home network through the WLAN AN. Specifically, the WLAN AN is connected to the 3GPP AAA server through the Wa interface, and connected to the WAG through the Wn interface. In the 3GPP home network, the 3GPP AAA server and the subscription locator function (SLF), the Home Subscriber Server (HSS), and the Home Location Register (referred to as the Home Location Register). "HLR"), Offline Charging System, Online Charging System (OCS), PDG, WAG are connected. The PDG is also connected to the WAG on the one hand and to the external network on the other hand. A tunnel can be established between the UE and the PDG. With this tunnel, the WLAN AN and WAG are transparent to the UE and the PDG.
图 2 示出了漫游状态下的基本模型, 该模型和非漫游状态的基 莫 型相比, 区别在于 WLAN AN并不是直接和 3GPP归属网络相连的, 而 是通过了 3GPP访问网络的中转。 具体地说, WLANAN分别通过 Wa接 口和 Wn接口和 3GPP访问网络中的 3GPP AAA代理、 WAG连接。 该 WAG和 3GPP归属网络中的 PDG连接, 3GPP AAA代理和 3GPP归属网 络中的 3GPPAAA服务器连接。 同样地, 在 ΌΈ和 PDG之间可以建立隧 道, 有了这个隧道, WLANAN和 WAG对 UE和 PDG是透明的。  Figure 2 shows the basic model in the roaming state. The difference between the model and the non-roaming state is that the WLAN AN is not directly connected to the 3GPP home network, but is transited by the 3GPP access network. Specifically, the WLAN AN is connected to the 3GPP AAA proxy, WAG in the 3GPP access network through the Wa interface and the Wn interface, respectively. The WAG is connected to the PDG in the 3GPP home network, and the 3GPP AAA proxy is connected to the 3GPP AAA server in the 3GPP home network. Similarly, a tunnel can be established between ΌΈ and PDG. With this tunnel, WLANAN and WAG are transparent to UE and PDG.

具体实施方式 为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对 本发明做进一步的详细描述。 detailed description The present invention will be further described in detail below with reference to the accompanying drawings.
首先简单介绍一下本发明的原理, 如图 3所示, 在步骤 31中, PDG 收到来自 WLAN UE的隧道建立请求后, 进入步骤 32, 由服务质量授权 模块, PDG和 AAA服务器确定授权给用户的 QoS参数。 其中, 服务质 量授权模块可以位于 AAA服务器中, 也可以位于 PDG中, 还可以是独 立的实体, 或位于其它任何网络实体中。 步骤 33至步骤 36完成网络中 各实体间的 QoS参数协商, 也就是将 QoS参数发送给网络中的各实体, 网絡中的各实体再根据自身情况判断是否可以接受该 QoS参数, 如果可 接收, 则向服务质量授权模块返回同意应答; 如果不可接收, 则向服务 质量授权模块返回带有建议的 QoS参数的应答或者失败应答。 服务质量 授权模块根据网络中各实体的应答进行决策, 如果决策失败或者收到的 是失败应答, 则向 WLAN UE返回隧道建立失败消息或隧道建立拒绝消 息, 并指明失败 /拒绝的原因, 终止整个流程不再向下进行, 并通知 AAA 服务器 /AAA代理, WAG和 WLAN以及其他相关实体删除该用户相关的 信息; 如果决策成功, 就进入步骤 37, 将最终确定的 QoS参数发送给需 要执行服务质量的网絡实体, 并接收相应的应答。 授权的 QoS参数可以 通过 AAA服务器发送给 WLAN AN, WAG和 PDG; 也可以直接发送给 WLAN AN, WAG和 PDG;也可以发送给 PDG,由 PDG发送给 WLAN AN, WAG; 也可以发送给 PDG, 由 PDG发送给 AAAJ良务器, 再由 AAA服 务器发送给 WLAN AN, WAG。 如果通过 AAA服务器发送, 当用户处于 漫游状态下, AAA服务器和网络中各实体之间的交互要通过访问网络中 AAA代理的中转。 First, the principle of the present invention is briefly introduced. As shown in FIG. 3, in step 31, after receiving the tunnel establishment request from the WLAN UE, the PDG proceeds to step 32, and the QoS module, the PDG, and the AAA server determine the authorization to the user. QoS parameters. The QoS authorization module may be located in the AAA server, or may be located in the PDG, or may be a separate entity, or located in any other network entity. Steps 33 to 36 complete the QoS parameter negotiation between the entities in the network, that is, the QoS parameters are sent to the entities in the network, and the entities in the network determine whether the QoS parameters can be accepted according to their own conditions. The consent response is returned to the quality of service authorization module; if not, the response or failure response with the suggested QoS parameters is returned to the quality of service authorization module. The QoS authorization module makes a decision according to the response of each entity in the network. If the decision fails or the failure response is received, the tunnel establishment failure message or the tunnel establishment rejection message is returned to the WLAN UE, and the reason of the failure/rejection is indicated, and the whole is terminated. The process is no longer going down, and the AAA server/AAA proxy is notified, the WAG and the WLAN and other related entities delete the information related to the user; if the decision is successful, the process proceeds to step 37, and the final determined QoS parameters are sent to the required quality of service. Network entity, and receive the corresponding response. The authorized QoS parameters can be sent to the WLAN AN, WAG and PDG through the AAA server; they can also be sent directly to the WLAN AN, WAG and PDG; they can also be sent to the PDG, which can be sent by the PDG to the WLAN AN, WAG; or can be sent to the PDG. It is sent by the PDG to the AAAJ server, which is then sent by the AAA server to the WLAN AN, WAG. If it is sent through the AAA server, when the user is roaming, the interaction between the AAA server and the entities in the network is to be accessed through the network. Transfer of AAA agent.
在步骤 38中 , 将最终确定的 QoS参数存贮在 AAA服务器 /AAA代 理中, 用来实现如计费, 业务统计等特定目的, 该步驟为可选步骤。 在 步骤 39 中, PDG向用户发送隧道建立请求成功响应, 最终协商的 QoS 参数可以发送在相应的消息中,也可以由 AAA服务器直接发送给用户终 端。 如果用户终端能够接收该 QoS参数, 就正常进行业务。 否则, 用户 终端可以根据默认的配置或用户的选择执行相应的操作, 如断开隧道, 如步骤 310所示。  In step 38, the finalized QoS parameters are stored in the AAA server/AAA proxy for specific purposes such as billing, service statistics, etc. This step is an optional step. In step 39, the PDG sends a tunnel establishment request success response to the user, and the finally negotiated QoS parameter may be sent in the corresponding message, or may be directly sent by the AAA server to the user terminal. If the user terminal is able to receive the QoS parameters, the service is normally performed. Otherwise, the user terminal can perform corresponding operations according to the default configuration or the user's selection, such as disconnecting the tunnel, as shown in step 310.
下面结合图 4详细说明本发明的第一个实施例, 对应于图 1所示的 WLAN UE处于非漫游状态下, 服务质量授权模块位于 PDG中的 QoS参 数协商。  A first embodiment of the present invention is described in detail below with reference to FIG. 4, corresponding to the QoS parameter negotiation in the PDG of the QoS UE in the non-roaming state shown in FIG.
如图 4所示, 在步骤 41中, WLAN UE向 PDG发送隧道建立请求, 执行认证、 授权步骤。 在该步驟中, PDG 中的服务盾量授权模块获知用 户关于业务 /隧道的 QoS要求。 其中, 服务质量授权模块是 PDG中的子 模块, 该模块与 PDG的接口是内部接口。 PDG中的服务质量授权模块有 两种方法得知用户关于业务 /隧道的 QoS要求:  As shown in FIG. 4, in step 41, the WLAN UE sends a tunnel establishment request to the PDG, and performs an authentication and authorization step. In this step, the service shield authorization module in the PDG learns the user's QoS requirements for the service/tunnel. The service quality authorization module is a submodule in the PDG, and the interface between the module and the PDG is an internal interface. The QoS authorization module in the PDG has two ways to know the QoS requirements of the user about the service/tunnel:
一种是 WLAN UE将其关于业务 /隧道的 QoS要求作为隧道建立请求 的一部分发送给 PDG中的服务质量授权模块。  One is that the WLAN UE sends its QoS requirements for the service/tunnel as part of the tunnel establishment request to the quality of service authorization module in the PDG.
另一种是在用户签约时, 在其签约信息中就已经将用户标识、 隧道 标识、 业务标识或 WLAN接入点名称(W-APN )等可以标识用户、 业务 的标识与相应的 QoS参数绑定, 用户只需要在隧道建立请求中携带部分 或全部这些标识信息, 在业务认证和授权过程中, PDG 中的服务质量授 00593 The other is that when the user signs the contract, the user ID, the tunnel identifier, the service identifier, or the WLAN access point name (W-APN) can be used to identify the identifier of the user and the service and the corresponding QoS parameters. The user only needs to carry some or all of the identification information in the tunnel establishment request. In the service authentication and authorization process, the quality of service in the PDG is granted. 00593
- 17- 权模块就能得知用户关于业务 /隧道的 QoS要求。 上述 QoS参数和用户、 业务的关联(或称 "绑定,,)关系包括动态数 据信息的绑定和静态数据信息绑定两种形式。 动态数据信息的绑定是指 业务进行时, 在与业务提供、 数据传输直接相关的网络实体中 (例如: WLAN AN WAG, PDG、 AAA服务器、 AAA代理等), 用户、 业务数 据流和 QoS参数间的关联关系; 静态数据信息的绑定是指和业务进行没 有直接关系, 涉及签约信息、 用户信息维护等工作的实体中的用户、 业 务数据流和 QoS参数间的关联关系,这些实体包括但不限于: HLR、 HSS、 策略服务器、 第三方服务器、 应用服务器以及其它相关实体。 - 17- The right module knows the user's QoS requirements for the service/tunnel. The association between the QoS parameters and the user and the service (or "binding,") includes two types of binding of dynamic data information and binding of static data information. Binding of dynamic data information refers to when the service is in progress. The service provider, the data transmission directly related to the network entity (for example: WLAN AN WAG, PDG, AAA server, AAA proxy, etc.), the relationship between the user, the service data flow and the QoS parameters; the binding of the static data information refers to There is no direct relationship between the service, the user, the service data flow and the QoS parameters in the entity involved in the subscription information, user information maintenance, etc., including but not limited to: HLR, HSS, policy server, third-party server, Application server and other related entities.
在 WLANAN、 WAG, PDG、 AAA服务器、 AAA代理、 HLR、 HSS、 策略服务器、 第三方服务器、 应用服务器以及其它相关实体中, QoS 参 数和用户的关联情况包括:  In WLANAN, WAG, PDG, AAA server, AAA proxy, HLR, HSS, policy server, third-party server, application server and other related entities, the QoS parameters and user associations include:
WLAN中用户连接相关的数据和 QoS参数关联;  Association of data related to user connections in the WLAN with QoS parameters;
隧道标识和 QoS参数以及其它信息的关联; 业务标识和 QoS参数以及其它信息的关联;  Association of tunnel identification with QoS parameters and other information; association of service identification with QoS parameters and other information;
接入点名称(Access Point Name, 简称 "APN" )和 QoS参数以及其 它信息的关联, 该 APN可以是 WLANAPN (简写为 "W-APN" );  The access point name ("APN") and the association of QoS parameters and other information, the APN may be a WLAN APN (abbreviated as "W-APN");
IP地址(包括源 IP地址、 目的 IP地址、封装 IP地址等)和端口(包 括源端口、 目的端口等) 与 QoS参数的关联; 用户标识和 QoS参数的关联;  Association of IP addresses (including source IP address, destination IP address, encapsulated IP address, etc.) and ports (including source ports, destination ports, etc.) with QoS parameters; association of user IDs and QoS parameters;
以上任意关联关系的任意組合。  Any combination of any of the above relationships.
QoS 参数包括但不限于: 带宽信息, 时延信息, 抖动信息, 信令数 据单元 (SDU)错误率, 数据包丢失率, 业务类别 (会话类, 流媒体类, 互 动类和后台类), 用户服务质量参数索引等。 QoS parameters include but are not limited to: bandwidth information, delay information, jitter information, signaling number According to unit (SDU) error rate, packet loss rate, service category (session class, streaming media class, interactive class and background class), user service quality parameter index, etc.
接着进入步骤 42, PDG中的服务盾量授权模块根据认证、 授权的结 果, 以及从策略服务器获得的关于用户的 QoS授权信息, 结合 PDG自身 情况, 做出对该用户的关于业务 /隧道的 QoS要求的结论(初步的), 确 定可以向用户提供的 QoS参数。  Then, proceeding to step 42, the service shield authorization module in the PDG performs QoS on the service/tunnel for the user according to the result of the authentication, the authorization, and the QoS authorization information about the user obtained from the policy server, in combination with the PDG itself. The required conclusions (preliminary) determine the QoS parameters that can be provided to the user.
上述 PDG的自身情况可以包括: 自身可用资源情况(例如: 可用带 宽, 可用存储器大小, 可用端口数等)和 /或运营商设置的配置情况。  The PDG's own situation may include: the availability of its own resources (for example: available bandwidth, available memory size, number of available ports, etc.) and / or configuration settings set by the operator.
上述策略服务器可以是 3GPP 中的策略决定功能(Policy Decision Function, 简称 "PDF" )。  The above policy server may be a Policy Decision Function ("PDF") in 3GPP.
接着进入步骤 43, PDG中的服务质量授权模块将步驟 42中得到的 关于业务 /P遂道的 QoS要求的初步结论发送给 AAA服务器, AAA服务器 存储该 QoS参数信息, 并在此后执行的步骤 44和步骤 45中, 由 AAA 服务器作为中间节点帮助 PDG完成与 WLAN和 WAG间的 QoS协商。 步驟 44和 45的执行可以有三种情况, 一是先执行步驟 44, 后执行步骤 45; 二是先执行步骤 45, 后执行步骤 44; 三是同时执行步骤 44和步驟 45。  Next, proceeding to step 43, the QoS authorization module in the PDG sends the preliminary conclusion about the QoS requirement of the service/P tunnel obtained in step 42 to the AAA server, and the AAA server stores the QoS parameter information, and step 44 is performed thereafter. And in step 45, the AAA server serves as an intermediate node to help the PDG complete QoS negotiation with the WLAN and the WAG. The execution of steps 44 and 45 can be performed in three cases. First, step 44 is performed first, and then step 45 is performed; second, step 45 is performed first, then step 44 is performed; third, step 44 and step 45 are performed simultaneously.
上述 AAA服务器可以是 3GPP AAA服务器。  The above AAA server may be a 3GPP AAA server.
本步骤中, AAA服务器对 QoS参数的存储可以不做, 因为本步裸中 AAA服务器所获得的 QoS参数只是一个初步的结果,在以后的步骤中还 会获得最终的 QoS参数, 只要保存最终的 QoS参数就可以了。  In this step, the AAA server may not store the QoS parameters, because the QoS parameters obtained by the AAA server in this step are only a preliminary result, and the final QoS parameters are obtained in the subsequent steps, as long as the final QoS parameters are saved. The QoS parameters are fine.
步骤 44可以分为以下 4个子步骤: 在子步骤 44a中, AAA服务器将 QoS参数发送给 WAG, WAG根据 自身情况做出判断: Step 44 can be divided into the following four sub-steps: In sub-step 44a, the AAA server sends the QoS parameters to the WAG, and the WAG makes a judgment based on its own situation:
如果能够接受该 QoS参数, 则执行子步骤 44b, 向 AAA服务器返回 同意应答, 然后执行子步骤 44d;  If the QoS parameter can be accepted, perform sub-step 44b, return a consent response to the AAA server, and then perform sub-step 44d;
如果不能接受该 QoS参数, 则执行子步骤 44c, 向 AAA服务器返回 由 WAG给出的 QoS参数建议应答, 或者返回失败应答, 然后执行子步 驟 44d。  If the QoS parameter is not acceptable, then sub-step 44c is performed to return a QoS parameter suggestion response given by the WAG to the AAA server, or to return a failure response, and then perform sub-step 44d.
在子步骤 44d中, AAA服务器将由 WAG返回的应答转发给 PDG中 的服务质量授权模块。  In sub-step 44d, the AAA server forwards the response returned by the WAG to the quality of service authorization module in the PDG.
之所以一定要由 AAA服务器在 PDG和 WAG之间作中介, 是因为 The reason why the AAA server must be used as an intermediary between PDG and WAG is because
WLAN UE和 PDG之间是一个隧道, WAG对 PDG是透明的, PDG无法 直接和 WAG交互。 There is a tunnel between the WLAN UE and the PDG. The WAG is transparent to the PDG, and the PDG cannot directly interact with the WAG.
上述 WAG的自身情况可以包括: 自身可用资源情况(例如: 可用带 宽, 可用存储器大小, 可用端口数等)和运营商设置的配置情况。  The above-mentioned WAG's own situation may include: the availability of its own resources (for example: available bandwidth, available memory size, number of available ports, etc.) and the configuration settings of the operator.
步骤 45可以分为以下 4个子步骤:  Step 45 can be divided into the following four sub-steps:
在子步骤 45a中, AAA服务器将 QoS参数发送给 WLANAN, WLAN AN根据自身情况做出判断:  In sub-step 45a, the AAA server sends the QoS parameters to the WLAN AN, and the WLAN AN makes a judgment based on its own situation:
如果能够接受该 QoS参数, 则执行子步骤 45b, 向 AAA服务器返回 同意应答, 然后执行子步骤 45d;  If the QoS parameter can be accepted, perform sub-step 45b, return a consent response to the AAA server, and then perform sub-step 45d;
如果不能接受该 QoS参数, 则执行子步骤 45c, 向 AAA服务器返回 由 WLAN AN给出的 QoS参数建议应答, 或者返回失败应答, 然后执行 子步驟 45d。 00593 If the QoS parameter is not acceptable, then sub-step 45c is performed to return a QoS parameter suggestion response given by the WLAN AN to the AAA server, or to return a failure response, and then sub-step 45d is performed. 00593
-20- 在子步骤 45d中, AAA服务器将由 WLAN AN返回的应答转发给 PDG。 -20- In sub-step 45d, the AAA server forwards the response returned by the WLAN AN to the PDG.
之所以一定要由 AAA服务器在 PDG和 WLAN A 之间作中介, 是 因为 WLAN UE和 PDG之间是一个隧道, WLAN AN对 PDG是透明的, PDG无法直接和 WLAN AN交互。 上述 WLAN AN的自身情况可以包括: 自身可用资源情况(例如: 可用带宽, 可用存储器大小, 可用端口数等)和运营商设置的配置情况。 上述 WLAN AN主要是指无线局域网接入网络(Wirless Local Area Network Access Network, 简称 "WLAN AN" ), 当然熟悉本领域的普通技 术人员也可以知道, 还可以包含 WLAN中的其它必要设务, 例如接入控 制器 (Access Controller, 简称 "AC" ), 接入服务器( Access Server, 简称 "AS" ), 本地认证授权和计费服务器等。  The reason why the AAA server must be interposed between the PDG and the WLAN A is because there is a tunnel between the WLAN UE and the PDG. The WLAN AN is transparent to the PDG, and the PDG cannot directly interact with the WLAN AN. The above-mentioned situation of the WLAN AN may include: the available resources of the self (for example: available bandwidth, available memory size, number of available ports, etc.) and the configuration settings of the operator. The WLAN AN is mainly referred to as a Wirless Local Area Network Access Network (WLAN AN), and those skilled in the art may also know that other necessary services in the WLAN may be included, for example. Access Controller ("AC"), Access Server ("AS"), local authentication and authorization, and accounting server.
接着进入步驟 46, PDG 中的服务质量授权模块根据步骤 44、 步骤 45获得的应答, 进行决策, 确定最终提供给用户的 QoS参数。 决策可能 有两种结果: Then, proceeding to step 46, the quality of service authorization module in the PDG makes a decision according to the response obtained in step 4 4 and step 45, and determines the QoS parameter finally provided to the user. Decisions can have two outcomes:
如果决策失败, 或者从 WLAN AN和 /或 WAG收到了失败应答, 则 进入子步骤 46a,向 WLAN UE返回隧道建立失败消息或隧道建立拒绝消 息, 并指明失败 /拒绝的原因, 还要通知 AAA服务器 /代理, WLANAN, WAG和其他相关实体删除与本次隧道建立请求相关的信息 (例如 AAA 服务器中在步骤 43保存的 QoS参数), 整个流程结束; 如果决策成功, 则执行步骤 47。 决策可以采用以下具体方法: 先判断 WAG、 WLAN AN返回的应答是否为同意应答, 如果是则认 为步骤 42中决定的 QoS参数可以被各实体所接受, 以步骤 42中决定的 QoS参数为最终的 QoS参数。 If the decision fails, or a failure response is received from the WLAN AN and/or WAG, then a sub-step 46a is entered to return a tunnel establishment failure message or a tunnel establishment rejection message to the WLAN UE, indicating the cause of the failure/rejection, and notifying the AAA server. /Proxy, WLANAN, WAG and other related entities delete the information related to the current tunnel establishment request (for example, the QoS parameters saved in step 43 in the AAA server), and the entire process ends; if the decision is successful, step 47 is performed. Decisions can take the following specific methods: First, it is determined whether the response returned by the WAG and the WLAN AN is an agreed response. If yes, the QoS parameter determined in step 42 is considered to be accepted by each entity, and the QoS parameter determined in step 42 is the final QoS parameter.
如果 WAG、 WLAN AN中至少有一个返回建议应答, 则找出建议应 答所携带的 QoS参数中最糟糕的那一个, 判断该 QoS参数能否满足进行 WLAN UE所请求业务的最基本要求, 如果可以, 则以该 QoS参数为最 终的 QoS参数, 否则执行上述子步骤 46a。  If at least one of the WAG and the WLAN AN returns a suggested response, find the worst one of the QoS parameters carried in the suggested response, and determine whether the QoS parameter satisfies the most basic requirement for performing the service requested by the WLAN UE, if Then, the QoS parameter is taken as the final QoS parameter, otherwise the above sub-step 46a is performed.
在本步骤以及步骤 42中, 对 QoS参数进行决策时, 可以依据以下信 白 ·  In this step and in step 42, when making decisions on QoS parameters, the following information can be used.
请求的服务质量, 服务质量授权信息, 建议的服务质量, 业务授权 信息, PDG的状态, 以及运营商预先配置在 PDG中的策略等。  Requested quality of service, quality of service authorization information, recommended quality of service, service authorization information, status of the PDG, and policies pre-configured by the operator in the PDG.
上述决策所依据的信息可以来源于以下实体:  The information on which the above decisions are based may be derived from the following entities:
AAA服务器, AAA代理, HLR/HSS, 策略服务器, WLAN接入网 关, WLANAN, WLAN UE, 以及 PDG。  AAA server, AAA proxy, HLR/HSS, policy server, WLAN access gateway, WLAN AN, WLAN UE, and PDG.
上述 PDG的状态包含当前负载情况和资源使用情况; 其中, 当前负载情况和资源使用情况具体可包含: 用户数, 已用带宽, 可 用带宽, 存储器使用情况, 以及端口使用情况等。  The status of the PDG includes the current load status and resource usage. The current load status and resource usage may include: the number of users, the used bandwidth, the available bandwidth, the memory usage, and the port usage.
这里把各实体向 PDG中的服务质量授权模块提供的信息总结如下: Here, the information provided by each entity to the Quality of Service Authorization Module in the PDG is summarized as follows:
AAA服务器 /代理向 PDG中的服务质量授权模块提供的信息可以是 业务授权信息, QoS授权信息, QoS参数和其指示标识的关联关系等。 The information provided by the AAA server/proxy to the quality of service authorization module in the PDG may be the service authorization information, the QoS authorization information, the association relationship between the QoS parameters and the indication identifier thereof, and the like.
策略服务器向 PDG中的服务质量授权模块提供的信息可以是业务授 权信息, QoS授权信息, QoS参数和其指示标识的关联关系等。 HLR及 HSS向 PDG中的服务质量授权模块提供的信息可以是业务 授权信息, QoS授权信息, QoS参数和其指示标识的关联关系等。 The information provided by the policy server to the quality of service authorization module in the PDG may be service authorization information, QoS authorization information, QoS parameters, and association relationships thereof. The information provided by the HLR and the HSS to the QoS authorization module in the PDG may be the service authorization information, the QoS authorization information, the association relationship between the QoS parameters and the indication identifier thereof, and the like.
WLAN接入网关向 PDG中的服务质量授权模块提供的信息可以是是 否接受 PDG通知中提供给用户设备的 QoS参数, 建议的 QoS参数或失 败应答等。  The information provided by the WLAN access gateway to the quality of service authorization module in the PDG may be a QoS parameter, a suggested QoS parameter or a failure response, etc., which is provided to the user equipment in the PDG notification.
WLAN AN向 PDG中的服务质量授权模块提供的信息可以是是否接 受 PDG通知中提供给用户设备的 QoS参数, 建议的 QoS参数或失败应 答等。  The information provided by the WLAN AN to the quality of service authorization module in the PDG may be whether to accept the QoS parameters provided to the user equipment in the PDG notification, the suggested QoS parameters or the failure response.
WLAN UE向 PDG中的服务质量授权模块提供的信息可以是 WLAN UE能够提供的 QoS参数, 要求的 QoS参数, 是否接受 PDG通知中提供 的 QoS参数等。  The information provided by the WLAN UE to the QoS authorization module in the PDG may be a QoS parameter that the WLAN UE can provide, a required QoS parameter, whether to accept the QoS parameter provided in the PDG notification, and the like.
在步骤 47中, PDG中的服务质量授权模块将步驟 46中确定的供给 WLAN UE的 QoS参数发送给 AAA服务器。 AAA服务器存储该信息用 于特定目的(例如: 计费的依据、 用于网管目的的 QoS和相关信息统计、 提供给其它服务器、 ***、 网络实体或第三方等等), 并由 AAA服务器 作为中间节点发送给 WLAN A 和 WAG,并接受来自 WLAN AN和 WAG 的应答。  In step 47, the quality of service authorization module in the PDG transmits the QoS parameters of the WLAN UE determined in step 46 to the AAA server. The AAA server stores this information for specific purposes (eg, basis for charging, QoS and related information statistics for network management purposes, provision to other servers, systems, network entities, or third parties, etc.), and is served by the AAA server as the middle The node sends to WLAN A and WAG and accepts replies from WLAN AN and WAG.
接着进入步骤 48, PDG向用户发送隧道建立请求成功响应, 在该消 息中, 将最终协商的 QoS参数发送给 WLAN UE。  Next, proceeding to step 48, the PDG sends a tunnel establishment request success response to the user, and in the message, the finally negotiated QoS parameter is sent to the WLAN UE.
接着进入步骤 49, WLAN UE判断是否可以接受来自 PDG的 QoS 参数, 如果是则正常进行业务, 否则, WLAN UE可以根据默认的配置或 用户的选择执行相应的操作, 例如: 断开隧道。 P T/CN2006/000593 Then, in step 49, the WLAN UE determines whether the QoS parameter from the PDG can be accepted. If yes, the service is performed normally. Otherwise, the WLAN UE can perform corresponding operations according to the default configuration or the user's selection, for example, disconnecting the tunnel. PT/CN2006/000593
-23- 具体来说, 步驟 49可以由以下子步驟组成: -23- Specifically, step 49 can be composed of the following substeps:
子步骤 49a, WLAN UE收到来自 PDG的隧道建立请求成功响应后, 比较其中携带的 QoS参数和原先请求的 QoS参数是否一致, 如果是则使 用原先请求的 QoS参数继续业务, 否则进入子步骤 49b;  Sub-step 49a, after receiving the successful response of the tunnel establishment request from the PDG, the WLAN UE compares whether the QoS parameter carried in the QoS parameter is consistent with the originally requested QoS parameter, and if yes, continues the service using the originally requested QoS parameter, otherwise proceeds to sub-step 49b. ;
子步骤 49b, WLAN UE判断隧道建立请求成功响应中携带的 QoS 参数是否可以接受, 如果是则使用该参数继续业务, 否则发起隧道断开 流程并向 PDG说明原因。  Sub-step 49b, the WLAN UE determines whether the QoS parameter carried in the successful response of the tunnel establishment request is acceptable, and if so, uses the parameter to continue the service; otherwise, the tunnel disconnection process is initiated and the reason is explained to the PDG.
下面结合图 5详细说明本发明的第二个实施例, 对应于图 2所示的 WLAN UE处于漫游状态下且服务质量授权模块位于 PDG中的 QoS参数 协商。  A second embodiment of the present invention is described in detail below with reference to FIG. 5, corresponding to the QoS parameter negotiation in which the WLAN UE shown in FIG. 2 is in a roaming state and the QoS authorization module is located in the PDG.
如图 5所示, 在步骤 51中, WLAN UE向 PDG发送隧道建立请求, 执行认证、 授权步骤。 在该步骤中, PDG 中的服务质量授权模块获知用 户关于业务 /隧道的 QoS要求。 其中, 服务质量授权模块是 PDG中的子 模块, 该模块与 PDG的接口是内部接口。 PDG中的服务质量授权模块有 两种方法得知用户关于业务 /隧道的 QoS要求:  As shown in FIG. 5, in step 51, the WLAN UE sends a tunnel establishment request to the PDG, and performs an authentication and authorization step. In this step, the QoS authorization module in the PDG learns the QoS requirements of the user for the service/tunnel. The service quality authorization module is a submodule in the PDG, and the interface between the module and the PDG is an internal interface. The QoS authorization module in the PDG has two ways to know the QoS requirements of the user about the service/tunnel:
一种是 WLAN UE将其关于业务 /隧道的 QoS要求作为隧道建立请求 的一部分发送给 PDG中的服务质量授权模块。 另一种是在用户签约时, 在其签约信息中就已经将用户标识、 隧道 标识、业务标识或接入点名称等可以标识用户、业务的标识与相应的 QoS 参数绑定, 用户只需要在隧道建立请求中携带部分或全部这些标识信息, 在业务认证和授权过程中, PDG 中的服务质量授权模块就能得知用户关 于业务 /隧道的 QoS要求。 接着进入步骤 52, PDG中的服务质量授权模块根据认证、 授权的结 果, 以及从策略服务器获得的关于用户的 QoS授权信息, 结合 PDG自身 情况, 做出对该用户的关于业务 /隧道的 QoS要求的结论(初步的), 确 定可以向用户提供的 QoS参数。 One is that the WLAN UE sends its QoS requirements for the service/tunnel as part of the tunnel establishment request to the quality of service authorization module in the PDG. The other is that when the user signs the contract, the user ID, the tunnel identifier, the service identifier, or the access point name can be identified in the subscription information, and the identifier of the user and the service can be bound to the corresponding QoS parameter. The user only needs to be in the user. The tunnel establishment request carries some or all of the identification information. In the service authentication and authorization process, the QoS authorization module in the PDG can learn the QoS requirements of the user about the service/tunnel. Then, proceeding to step 52, the QoS authorization module in the PDG makes a QoS requirement for the service/tunnel of the user according to the result of the authentication, the authorization, and the QoS authorization information about the user obtained from the policy server, in combination with the PDG itself. The conclusion (preliminary) determines the QoS parameters that can be provided to the user.
PDG的自身情况可以包括: 自身可用资源情况(例如: 可用带宽, 可用存储器大小, 可用端口数等)和运营商设置的配置情况。  The PDG's own situation can include: the availability of its own resources (for example: available bandwidth, available memory size, number of available ports, etc.) and the configuration settings of the operator.
策略服务器可以是 3GPP 中的策略决定功能 (Policy Decision Function, 简称 "PDF" )。  The policy server can be a Policy Decision Function ("PDF") in 3GPP.
接着进入步驟 53 , PDG中的服务质量授权模块将步驟 52中得到的 关于业务 /隧道的 QoS要求的结论发送给 AAA服务器, AAA服务器存储 该 QoS参数信息,并在此后执行步骤 54和步骤 55中,由 AAA服务器 /AAA 代理作为中间节点帮助 PDG中的服务质量授权模块完成与 WLANAN和 WAG间的 QoS协商。 步骤 54和 55的执行可以有三种情况, 一是先执行 步骤 54, 后执行步骤 55; 二是先执行步驟 55, 后执行步驟 54; 三是同 时执行步骤 54和步骤 55。 Then, proceeding to step 53, the QoS authorization module in the PDG sends the conclusion about the QoS requirement of the service/tunnel obtained in step 52 to the AAA server, and the AAA server stores the QoS parameter information, and then performs steps 54 and 55 thereafter. The AAA server/AAA proxy acts as an intermediate node to help the QoS authorization module in the PDG complete QoS negotiation with the WLAN AN and WAG. There are three cases for the execution of steps 54 and 55. First, step 54 is performed first, and then step 55 is executed. Second, step 55 is performed first, then step 5 4 is performed; third, step 54 and step 55 are performed simultaneously.
上述 AAA服务器可以是 3GPP AAA服务器。  The above AAA server may be a 3GPP AAA server.
本步骤中, AAA服务器对 QoS参数的存储可以不做, 因为本步骤中 AAA服务器所获得的 QoS参数只是一个初步的结果,在以后的步骤中还 会获得最终的 QoS参数, 只要保存最终的 QoS参数就可以了。  In this step, the AAA server may not store the QoS parameters, because the QoS parameters obtained by the AAA server in this step are only a preliminary result, and the final QoS parameters are obtained in the subsequent steps, as long as the final QoS is saved. The parameters are fine.
步骤 54可以分为以下六个子步骤:  Step 54 can be divided into the following six sub-steps:
在子步骤 54a中, AAA服务器将 QoS参数发送给 AAA代理; 此后进入子步骤 54b中, AAA代理将 QoS参数发送给 WAG, WAG 根据自身情况做出判断: In sub-step 54a, the AAA server sends the QoS parameters to the AAA proxy; thereafter, in sub-step 54b, the AAA proxy sends the QoS parameters to WAG, WAG. Make judgments based on your own situation:
如果能够接受该 QoS参数, 则执行子步骤 54c, 向 AAA代理返回同 意应答, 然后执行子步驟 54e;  If the QoS parameter can be accepted, sub-step 54c is performed to return a consent response to the AAA proxy, and then sub-step 54e is performed;
如果不能接受该 QoS参数, 则执行子步骤 54d, 向 AAA代理返回由 WAG给出的 QoS参数建议应答, 或者返回失败应答, 然后执行子步骤 54e。  If the QoS parameter is not acceptable, then sub-step 54d is performed to return a QoS parameter suggestion response given by the WAG to the AAA proxy, or to return a failure response, and then perform sub-step 54e.
其中, AAA代理在转发 QoS参数时, 有两种不同的方式: 一种是透传,即不对从 AAA服务器收到的 QoS参数做任何修改就转 发给 WAG和 WLAN;  The AAA proxy forwards the QoS parameters in two different ways: One is transparent transmission, that is, it is forwarded to the WAG and the WLAN without any modification to the QoS parameters received from the AAA server;
另一种是根据漫游网络的状态,以及运营商的配置和策略,对从 AAA 服务器收到的 QoS参数进行修改, 然后转发给 WAG和 WLAN AN。  The other is to modify the QoS parameters received from the AAA server according to the state of the roaming network and the configuration and policy of the operator, and then forward it to the WAG and the WLAN AN.
在子步骤 54e中, AAA代理将由 WAG返回的应答转发给向 AAA服 务器;  In sub-step 54e, the AAA proxy forwards the response returned by the WAG to the AAA server;
此后进入子步骤 54f, AAA服务器将 AAA代理转发的应答再转发给 PDG。  Thereafter, the sub-step 54f is entered, and the AAA server forwards the response forwarded by the AAA proxy to the PDG.
和第一个实施例中的步骤 44相比, 本实施例增加了 AAA代理的中 转步骤, 这是因为 WLAN UE处在访问网络中, AAA服务器无法直接和 访问网络中的 WAG交互, 所以只能由访问网络中的 AAA代理中转。  Compared with step 44 in the first embodiment, this embodiment adds a transit step of the AAA proxy, because the WLAN UE is in the access network, and the AAA server cannot directly interact with the WAG in the visited network, so Redirected by an AAA proxy in the visited network.
上述 WAG的自身情况可以包括: 自身可用资源情况(例如: 可用带 宽, 可用存储器大小, 可用端口数等)和运营商设置的配置情况。  The above-mentioned WAG's own situation may include: the availability of its own resources (for example: available bandwidth, available memory size, number of available ports, etc.) and the configuration settings of the operator.
步骤 55可以分为以下六个子步骤:  Step 55 can be divided into the following six sub-steps:
在子步骤 55a中, AAA服务器将 QoS参数发送给 AAA代理; 此后进入子步骤 55b中, AAA代理将 QoS参数发送给 WLAN AN, WLANAN根据自身情况做出判断: In sub-step 55a, the AAA server sends the QoS parameters to the AAA proxy; Thereafter, in sub-step 55b, the AAA proxy sends the QoS parameters to the WLAN AN, and the WLANAN makes a judgment according to its own situation:
如果能够接受该 QoS参数, 则执行子步驟 55c, 向 AAA代理返回同 意应答, 然后执行子步骤 55e;  If the QoS parameter can be accepted, perform sub-step 55c, return a consent response to the AAA proxy, and then perform sub-step 55e;
如果不能接受该 QoS参数, 则执行子步骤 55d, 向 AAA代理返回由 If the QoS parameter cannot be accepted, then sub-step 55d is performed, returning to the AAA proxy.
WLAN AN给出的 QoS参数建议应答, 或者返回失败应答, 然后执行子 步骤 55e。 The QoS parameter given by the WLAN AN suggests a response, or returns a failure response, and then performs sub-step 55e.
在子步骤 55e中, AAA代理将由 WLAN AN返回的应答转发给向 AAA服务器;  In sub-step 55e, the AAA proxy forwards the response returned by the WLAN AN to the AAA server;
此后进入子步骤 55f, AAA服务器将 AAA代理转发的应答再转发给 Thereafter, the sub-step 55f is entered, and the AAA server forwards the response forwarded by the AAA proxy to the
PDG„ PDG„
和第一个实施例的步骤 45相比, 本实施例增加了 AAA代理的中转 步骤, 这是因为 WLAN UE处在访问网络中, AAA服务器无法直接和访 问网络中的 WLANAN交互, 所以只能由访问网络中的 AAA代理中转。  Compared with step 45 of the first embodiment, this embodiment adds a transfer step of the AAA proxy. Because the WLAN UE is in the access network, the AAA server cannot directly interact with the WLAN AN in the visited network, so it can only be Access the AAA proxy relay in the network.
上述 WLAN AN的自身情况可以包括: 自身可用资源情况(例如: 可用带宽, 可用存储器大小, 可用端口数等)和运营商设置的配置情况。  The above-mentioned situation of the WLAN AN may include: the available resources of the self (for example: available bandwidth, available memory size, number of available ports, etc.) and the configuration settings of the operator.
接着进入步骤 56, PDG根据步骤 54、 步骤 55获得的应答, 进行决 策, 确定最终提供给用户的 QoS参数。 决策可能有两种结果:  Then, proceeding to step 56, the PDG performs a decision according to the response obtained in step 54 and step 55 to determine the QoS parameters finally provided to the user. Decisions can have two outcomes:
如果决策失败, 或者在 54b/55b 中收到了失败应答, 则进入子步驟 56a, 向 WLAN UE返回隧道建立失败消息或隧道建立拒绝消息, 并指明 失败 /拒绝的原因, 还要通知 AAA服务器 /代理, WLAN AN, WAG和其 他相关实体删除与本次随道建立请求相关的信息(例如 AAA服务器中在 步驟 53保存的 QoS参数), 整个流程结束; If the decision fails, or if a failure response is received in 54b/55b, then a sub-step 56a is entered to return a tunnel establishment failure message or a tunnel establishment rejection message to the WLAN UE, indicating the cause of the failure/rejection, and also notifying the AAA server/agent , WLAN AN, WAG, and other related entities delete information related to this accompaniment request (eg, in the AAA server) Step 53 saves the QoS parameter), the entire process ends;
如果决策成功, 则执行步骤 57。  If the decision is successful, go to step 57.
在步驟 57中, PDG中的服务质量授权模块将步骤 56中确定的供给 WLAN UE的 QoS参数发送给 AAA服务器。 AAA服务器存储该信息用 于特定目的(例如: 计费的依据、 用于网管目的的 QoS和相关信息统计、 提供给其它服务器、 ***、 网络实体或第三方等等), 并由 AAA服务器 和 AAA代理作为中间节点发送给 WLAN AN和 WAG,并接受来自 WLAN AN和 WAG的应答。 和第一个实施例中的步驟 47相比, 本步骤中增加 了 AAA代理的中转步骤。  In step 57, the quality of service authorization module in the PDG transmits the QoS parameters of the WLAN UE determined in step 56 to the AAA server. The AAA server stores this information for specific purposes (eg, basis for billing, QoS and related information statistics for network management purposes, provision to other servers, systems, network entities or third parties, etc.), and is provided by the AAA server and AAA. The proxy is sent as an intermediate node to the WLAN AN and WAG and accepts responses from the WLAN AN and WAG. In contrast to step 47 in the first embodiment, the transfer step of the AAA agent is added in this step.
接着进入步驟 58, PDG向用户发送隧道建立请求成功响应, 在该消 息中, 将最终协商的 QoS参数发送给 WLAN UE。  Then, the process proceeds to step 58, the PDG sends a tunnel establishment request success response to the user, and in the message, the finally negotiated QoS parameter is sent to the WLAN UE.
接着进入步骤 59, WLAN UE判断是否可以接受来自 PDG中服务质 量授权模块的 QoS参数, 如果是则正常进行业务, 否则, WLAN UE可 以根据默认的配置或用户的选择执行相应的操作, 例如: 断开隧道。  Then, proceeding to step 59, the WLAN UE determines whether the QoS parameter from the quality of service authorization module in the PDG can be accepted. If yes, the service is performed normally. Otherwise, the WLAN UE can perform corresponding operations according to the default configuration or the user's selection, for example: Open the tunnel.
下面结合图 6详细说明本发明的第三个实施例, 服务盾量授权模块 位于 AAA服务器中的 QoS参数协商。  Next, a third embodiment of the present invention will be described in detail with reference to Fig. 6, in which the service shield authorization module is located in the AAA server for QoS parameter negotiation.
如图 6所示, 在步骤 61中, WLAN UE向 PDG发送隧道建立请求, 执行认证、 授权步驟。 并且, 在 WLAN TJE发送的隧道建立请求中, 包 含用户关于业务 /隧道的 QoS请求。有两种方法可以使用户关于业务 /隧道 的 QoS要求包含在隧道建立请求中:  As shown in FIG. 6, in step 61, the WLAN UE sends a tunnel establishment request to the PDG, and performs an authentication and authorization step. And, in the tunnel establishment request sent by the WLAN TJE, the QoS request of the user about the service/tunnel is included. There are two ways to include the user's QoS requirements for traffic/tunnel in the tunnel establishment request:
一种是 WLAN UE将其关于业务 /P 道的 QoS要求作为隧道建立请求 的一部分发送给 PDG。 另一种是在用户签约时, 在其签约信息中就已经将用户标识、 隧道 标识、业务标识或接入点名称等可以标识用户、业务的标识与相应的 QoS 参数绑定, 用户只需要在隧道建立请求中携带部分或全部这些标识信息, 在业务认证和授权过程中, PDG能得知用户关于业务 /隧道的 QoS要求。 One is that the WLAN UE sends its QoS requirements for the service/P-channel to the PDG as part of the tunnel establishment request. The other is that when the user signs the contract, the user ID, the tunnel identifier, the service identifier, or the access point name can be identified in the subscription information, and the identifier of the user and the service can be bound to the corresponding QoS parameter. The user only needs to be in the user. The tunnel establishment request carries part or all of the identification information. During the service authentication and authorization process, the PDG can know the QoS requirements of the user about the service/tunnel.
接着, 进入步骤 62, PDG向 AAA服务器发起认证、 授权请求, 其 中, 包括对 QoS进行授权的请求。 需要说明的是, 当用户处在漫游状态 下, PDG通过 AAA代理向 AAA服务器发起认证、 授权请求。 这是因为 WLAN UE处在访问网络中, PDG服务器无法直接和访问网络中的 AAA 服务器交互, 所以只能由访问网络中的 AAA代理中转。 另外, 对 QoS 请求进行授权的模块是 AAA服务器中的服务质量授权模块, 该模块与 AAA服务器的接口是内部接口。 AAA服务器可以是 3GPP AAA服务器。  Next, proceeding to step 62, the PDG initiates an authentication and authorization request to the AAA server, where the request includes authorization for QoS. It should be noted that when the user is in the roaming state, the PDG initiates an authentication and authorization request to the AAA server through the AAA proxy. This is because the WLAN UE is in the access network, and the PDG server cannot directly interact with the AAA server in the access network, so it can only be transferred by the AAA proxy in the visited network. In addition, the module that authorizes the QoS request is the quality of service authorization module in the AAA server, and the interface between the module and the AAA server is an internal interface. The AAA server can be a 3GPP AAA server.
接着,进入步骤 63, AAA服务器中的服务质量授权模块从 HLR HSS 获取用户的认证、 授权信息, 对用户进行认证, 以及对用户的隧道建立 请求进行授权, 提供一个授权的 QoS。 也就是说, 服务质量授权模块根 据 PDG发来的请求的 QoS和 AAA服务器中存储的用户的签约的 QoS参 数 (用户的签约的 QoS参数从 HLR/HSS获取), 以及可能从策略服务器获 得的关于用户的 QoS授权信息,做出对该用户的关于业务 /隧道的 QoS要 求的结论, 确定可以向用户提供的 QoS参数,然后对用户的隧道建立请求 进行授权, 提供一个授权的 QoS。 其中, 策略服务器可以是 3GPP中的策 略决定功能(Policy Decision Function, 简称 " PDF" )。  Then, proceeding to step 63, the QoS authorization module in the AAA server obtains the user's authentication and authorization information from the HLR HSS, authenticates the user, and authorizes the tunnel establishment request of the user, and provides an authorized QoS. That is, the quality of service authorization module obtains the QoS of the request sent by the PDG and the subscribed QoS parameter of the user stored in the AAA server (the subscribed QoS parameter of the user is obtained from the HLR/HSS), and may be obtained from the policy server. The user's QoS authorization information, conclusions about the QoS requirements of the user for the service/tunnel, determining the QoS parameters that can be provided to the user, and then authorizing the user's tunnel establishment request to provide an authorized QoS. The policy server may be a Policy Decision Function ("PDF") in 3GPP.
接着, 进入步驟 64, AAA服务器向 PDG返回授权结果, 其中包括 授权的 QoS。当用户处在漫游状态下, AAA服务器通过 AAA代理向 PDG 返回授权结果。 这是因为 WLAN UE处在访问网络中, AAA服务器无法 直接和访问网络中的 PDG交互, 所以只能由访问网 έ备中的 AAA代理中 转。 其中, AAA代理在转发 QoS参数时, 有两种不同的方式: Next, proceeding to step 64, the AAA server returns an authorization result to the PDG, including the authorized QoS. When the user is in the roaming state, the AAA server passes the AAA proxy to the PDG. Returns the authorization result. This is because the WLAN UE is in the access network, and the AAA server cannot directly interact with the PDG in the access network, so it can only be transferred by the AAA proxy in the access network backup. Among them, the AAA proxy has two different ways when forwarding QoS parameters:
一种是透传,即不对从 AAA服务器收到的 QoS参数做任何修改就转 发给 PDG ;  One is transparent transmission, that is, it is forwarded to the PDG without any modification to the QoS parameters received from the AAA server;
另一种是根据漫游网络的状态,以及运营商的配置和策略,对从 AAA 服务器收到的 QoS参数进行修改, 然后转发给 PDG。  The other is to modify the QoS parameters received from the AAA server according to the state of the roaming network and the configuration and policy of the operator, and then forward it to the PDG.
在步驟 65、 66中, AAA服务器将授权的 QoS参数通知给 WLAN和 WAG, 并获得应答。 同样, 如果用户处在漫游状态下, AAA服务器要通 过 AAA代理转发,并且, 在转发 QoS参数时, 有两种不同的方式:  In steps 65, 66, the AAA server notifies the WLAN and WAG of the authorized QoS parameters and obtains a response. Similarly, if the user is roaming, the AAA server is forwarded through the AAA proxy, and there are two different ways to forward the QoS parameters:
一种是透传,即不对从 AAA服务器收到的 QoS参数做任何修改就转 发给 WLAN AN和 /或 WAG;  One is transparent transmission, that is, no modification to the QoS parameters received from the AAA server is forwarded to the WLAN AN and / or WAG;
另一种是根据漫游网络的状态,以及运营商的配置和策略,对从 AAA 服务器收到的 QoS参数进行修改, 然后转发给 WLAN AN和 /或 WAG。  The other is to modify the QoS parameters received from the AAA server according to the state of the roaming network and the configuration and policies of the operator, and then forward it to the WLAN AN and/or WAG.
接着, 进入步骤 67, AAA服务器存储最终授权的 QoS参数。 AAA 服务器存储该信息用于特定目的, 例如: 计费的依据、 用于网管目的的 QoS 和相关信息统计、 提供给其它服务器、 ***、 网络实体或第三方等 等。  Next, proceeding to step 67, the AAA server stores the final authorized QoS parameters. The AAA server stores this information for specific purposes, such as: basis for charging, QoS and related information statistics for network management purposes, and provision to other servers, systems, network entities, or third parties.
接着, 进入步骤 68, PDG向用户发送隧道建立请求成功响应, 在该 消息中, 将最终协商的 QoS参数发送给 WLAN UE。  Next, proceeding to step 68, the PDG sends a tunnel establishment request success response to the user, and in the message, the finally negotiated QoS parameter is sent to the WLAN UE.
接着, 进入步骤 69, WLAN UE判断隧道建立请求成功响应中携带 的 QoS参数是否可以接受, 如果是则使用该参数继续业务, 否则 WLAN P T/CN2006/000593 Then, proceeding to step 69, the WLAN UE determines whether the QoS parameter carried in the successful response of the tunnel establishment request is acceptable, and if yes, uses the parameter to continue the service, otherwise the WLAN PT/CN2006/000593
-30--30-
UE可以根据默认的配置或用户的选择执行相应的操作,例如:断开隧道。 The UE can perform corresponding operations according to the default configuration or the user's selection, for example, disconnecting the tunnel.
最后, 在步骤 610 中, 实施该服务质量的网络中各实体返回实际提 供给用户的 QoS参数。由于 AAA服务器 / AAA代理是直接将最终协商的 Finally, in step 610, each entity in the network implementing the quality of service returns a QoS parameter that is actually provided to the user. Since the AAA server / AAA proxy is directly negotiated
QoS参数发送给网络中的各实体,所以,在业务开始传输后, WLANAN, WAG和 PDG利用计费信令向 AAA服务器 I AAA代理返回实际提供给 用户的 QoS参数, 使 AAA服务器能到达更为准确的计费等目的。 The QoS parameters are sent to the entities in the network. Therefore, after the traffic starts to be transmitted, the WLAN AN, WAG, and PDG use the charging signaling to return the QoS parameters actually provided to the user to the AAA server I AAA proxy, so that the AAA server can reach more. Accurate billing and other purposes.
下面结合图 7详细说明本发明的第四个实施例, 服务质量授权模块 独立存在的 QoS参数协商。  Next, a fourth embodiment of the present invention will be described in detail with reference to FIG. 7, in which the QoS parameter negotiation of the QoS authorization module exists independently.
如图 7所示, 在步骤 71中, WLAN UE向 PDG发送隧道建立请求, 执行认证、 授权步骤。 并且, 在 WLAN UE发送的隧道建立请求中, 包 含用户关于业务 /隧道的 QoS请求。 该步驟与步骤 61完全相同, 在此不 再赘述。  As shown in FIG. 7, in step 71, the WLAN UE sends a tunnel establishment request to the PDG, and performs an authentication and authorization step. And, in the tunnel establishment request sent by the WLAN UE, the QoS request of the user about the service/tunnel is included. This step is identical to step 61 and will not be described here.
步驟 72的执行有两种情况, 执行步骤 72'或者执行步骤 72"。 步驟 72'和步骤 72"是两种独立的可能,相互间没有关系。 下面分别对步骤 72'、 步骤 72"进行说明。 There are two cases of execution of step 72, step 72' or step 72". Steps 72' and 72" are two independent possibilities, and have no relationship with each other. Steps 72 ' and 72 will be described below.
在步骤 72'中, PDG向服务质量授权模块发起授权请求, 服务质量授 权模块对请求进行授权。 如果服务质量授权模块上有用户相关的签约信 息,则服务 量授权模块直接对请求进行授权,并向 PDG发出授权应答; 如果服务质量授权模块上没有用户相关的签约信息, 则服务质量授权模 块需要向 AAA服务器获取用户的签约信息 (包括签约的 QoS), 当然, 用 户的签约信息(包括签约的 QoS)也可以从其他网络实体获得, 然后, 向 PDG发出授权应答。 在步骤 72"中, PDG向 AAA服务器发起认证、 授权请求, AAA服 务器判断需要进行 QoS授权, 就向服务盾量授权模块请求 QoS授权。 服 务质量授权模块根据用户相关的签约信息对 QoS 请求进行授权, 并向 AAA服务器发出 QoS授权应答。最后, 由 AAA服务器向 PDG发出授权 应答, 该授权应答中包含 QoS授权。 In step 72', the PDG initiates an authorization request to the quality of service authorization module, and the quality of service authorization module authorizes the request. If the service quality authorization module has user-related subscription information, the service authorization module directly authorizes the request and sends an authorization response to the PDG; if there is no user-related subscription information on the service quality authorization module, the service quality authorization module needs The user's subscription information (including the contracted QoS) is obtained from the AAA server. Of course, the user's subscription information (including the contracted QoS) can also be obtained from other network entities, and then an authorization response is sent to the PDG. In step 72", the PDG initiates an authentication and authorization request to the AAA server, and the AAA server determines that the QoS authorization is required, and requests the QoS authorization from the service shield authorization module. The quality of service authorization module authorizes the QoS request according to the subscription information related to the user. And issuing a QoS authorization response to the AAA server. Finally, the AAA server sends an authorization response to the PDG, which includes the QoS authorization.
上述 AAA服务器可以是 3GPP AAA服务器。  The above AAA server may be a 3GPP AAA server.
步骤 73的执行有三种情况, 执行步骤 73', 或者执行步骤 73", 或者 执行步骤 73'"。 步骤 73'、 步骤 73"和步骤 73"'是三种独立的可能, 相互间 没有关系。 下面分别对步骤 73'、 步骤 73"以及步骤 73",进行说明。  There are three cases of execution of step 73, step 73' is performed, or step 73" is performed, or step 73'" is performed. Step 73', Step 73" and Step 73"' are three independent possibilities and have nothing to do with each other. Steps 73', 73, and 73" will be described below.
在步驟 73'中, 服务质量授权模块将 QoS参数通知给 AAA服务器并 获得应答,再由 AAA服务器通知给 WLAN AN, WAG和 /或 PDG并获得 应答。  In step 73', the quality of service authorization module notifies the AAA server of the QoS parameters and obtains a response, and then the AAA server notifies the WLAN AN, WAG and/or PDG and obtains a response.
在步骤 73"中, 服务质量授权模块将 QoS参数通知给 PDG并获得应 答, 由 PDG通知给 AAA服务器并获得应答, 再由 AAA服务器通知给 WLANAN, WAG并获得应答。  In step 73", the quality of service authorization module notifies the PDG of the QoS parameters and obtains the response, and the PDG notifies the AAA server and obtains a response, and then the AAA server notifies the WLAN AN, WAG and obtains a response.
在步骤 73" '中,服务质量授权模块将 QoS参数通知给 PDG并获得应 答, 由 PDG通知给 WLANAN、 WAG并获得应答。  In step 73"', the quality of service authorization module notifies the PDG of the QoS parameters and obtains an answer, and the PDG notifies the WLAN AN, WAG and obtains a response.
当然, 如果用户在漫游状态下, AAA服务器仍需通过 AAA代理与 PDG、 WLAN AN > WAG等网络实体进行交互, AAA代理的转发方式有 两种:  Of course, if the user is roaming, the AAA server still needs to interact with the network entity such as PDG and WLAN AN > WAG through the AAA proxy. There are two ways to forward the AAA proxy:
一种是透传,即不对从 AAA服务器收到的 QoS参数故任何修改就转 发给网络中各实体 ; 另一种是根据漫游网络的状态,以及运营商的配置和策略,对从 AAA 服务器收到的 QoS参数进行修改, 然后转发给网络中的各实体。 One is transparent transmission, that is, no modification to the QoS parameters received from the AAA server is forwarded to each entity in the network; The other is to modify the QoS parameters received from the AAA server according to the state of the roaming network and the configuration and policies of the operator, and then forward them to the entities in the network.
在步驟 74中, AAA服务器存储最终授权的 QoS参数。 AAA服务器 存储该信息用于特定目的, 例如: 计费的依据、 用于网管目的的 QoS和 相关信息统计、 提供给其它服务器、 ***、 网络实体或第三方等等。  In step 74, the AAA server stores the final authorized QoS parameters. The AAA server stores this information for specific purposes, such as: basis for charging, QoS for network management purposes, and related information statistics, provided to other servers, systems, network entities, or third parties.
在步骤 75中, PDG向用户发送隧道建立请求成功响应,在该消息中, 将最终协商的 QoS参数发送给 WLAN UE0 In step 75, the PDG sends a tunnel establishment request success response to the user, in which the finally negotiated QoS parameters are sent to the WLAN UE 0.
在步骤 76中, WLAN UE判断隧道建立请求成功响应中携带的 QoS 参数是否可以接受, 如果是则使用该参数继续业务, 否则 WLAN UE可 以根据默认的配置或用户的选择执行相应的操作, 例如: 断开隧道。  In step 76, the WLAN UE determines whether the QoS parameter carried in the successful response of the tunnel establishment request is acceptable, and if yes, uses the parameter to continue the service, otherwise the WLAN UE may perform corresponding operations according to the default configuration or the user's selection, for example: Disconnect the tunnel.
下面结合图 8详细说明本发明的第五个实施例, 服务质量授权模块 独立存在的 QoS参数协商。  The fifth embodiment of the present invention will be described in detail below with reference to FIG. 8, in which the QoS parameter negotiation of the QoS module is independent.
如图 8所示, 在步骤 81中, WLAN UE向 PDG发送隧道建立请求, 执行认证、 授权步骤。 该步骤与步驟 71完全相同, 在此不再赘述。  As shown in FIG. 8, in step 81, the WLAN UE sends a tunnel establishment request to the PDG, and performs an authentication and authorization step. This step is identical to step 71 and will not be described here.
步骤 82的执行有两种情况,执行步骤 82'或者执行步驟 82"。步骤 82'、 步骤 82"与步骤 72'、 步骤 72"完全相同, 都是决定最终向用户提供的 QoS 参数的两种独立情况, 在此不再赘述。  There are two cases in the execution of step 82, and step 82' is performed or step 82 is performed. Step 82', step 82" is identical to step 72' and step 72", and both are two types of QoS parameters that are finally provided to the user. Independent situation, no longer repeat here.
步骤 83的执行有几种情况, 执行步骤 83', 或者执行步骤 83", 或者 执行步骤 83"', 或者执行步骤 83"", 或者执行步驟 83'""。 步骤 83' -步骤 83""'是几种独立的可能, 相互间没有关系。 下面分别说明步骤 83' -步骤 83'""。 There are several cases in which the execution of step 83 is performed, step 83' is performed, or step 8 3 ", or step 83"' is performed, or step 83"" is performed, or step 83'" is performed. Step 8 3 ' - Step 83 ""' is a few independent possibilities, and has nothing to do with each other. Steps 83' - 83'"" are respectively explained below.
在步骤 83'中, 服务质量授权模块将 QoS参数通知给 AAA服务器并 获得应答, 由 AAA服务器通知给 WLAN AN和 /或 WAG并获得应答。 在步骤 83"中, 服务质量授权模块将 QoS参数通知给 AAA服务器并 获得应答, 由 AAA服务器通知给 WAG并获得应答。 In step 83', the quality of service authorization module notifies the AAA server of the QoS parameters and A response is obtained, notified to the WLAN AN and/or WAG by the AAA server and answered. In step 83", the quality of service authorization module notifies the AAA server of the QoS parameters and obtains a response, and the AAA server notifies the WAG and obtains a response.
在步骤 83",中,服务质量授权模块将 QoS参数通知给 AAA服务器并 获得应答, 由 AAA服务器通知给 WLAN AN并获得应答。  In step 83", the quality of service authorization module notifies the AAA server of the QoS parameters and obtains a response, and the AAA server notifies the WLAN AN and obtains a response.
在步骤 83""中, 服务质量授权模块将 QoS参数通知给 AAA服务器 并获得应答, 由 AAA服务器通知给 WAG和 PDG并获得应答。  In step 83"", the quality of service authorization module notifies the AAA server of the QoS parameters and obtains a response, and the AAA server notifies the WAG and the PDG and obtains a response.
在步骤 83 '""中, 服务质量授权模块将 QoS参数通知给 AAA服务器 并获得应答, 由 AAA服务器通知给 WLAN AN和 PDG并获得应答。  In step 83 '"", the quality of service authorization module notifies the AAA server of the QoS parameters and obtains a response, and the AAA server notifies the WLAN AN and the PDG and obtains a response.
上述 AAA服务器可以是 3GPP AAA服务器。  The above AAA server may be a 3GPP AAA server.
其实,服务质量授权模块可以将 QoS参数通过 AAA服务器发送给任 何需要服务质量的网络实体中的任何一个, 或其中的任何组合。 步骤 83' -步骤 83'""只是步驟 8的部分可能情况。 当然, 如果用户在漫游状态下, AAA服务器仍需通过 AAA代理与 PDG、 WLAN AN ^ WAG等网络实体 进行交互, AAA代理的转发方式在步骤 73中已详细说明,在此不再赘述。  In fact, the QoS authorization module can send QoS parameters to any of the network entities requiring quality of service, or any combination thereof, through the AAA server. Step 83' - Step 83'"" is only part of the possible case of Step 8. Of course, if the user is in the roaming state, the AAA server still needs to interact with the network entity such as the PDG and the WLAN AN ^ WAG through the AAA proxy. The forwarding mode of the AAA proxy is described in detail in step 73 and will not be described here.
在步骤 84中 , AAA服务器存储最终授权的 QoS参数。 AAA服务器 存储该信息用于特定目的, 例如: 计费的依据、 用于网管目的的 QoS和 相关信息统计、 提供给其它服务器、 ***、 网络实体或第三方等等。  In step 84, the AAA server stores the final authorized QoS parameters. The AAA server stores this information for specific purposes, such as: basis for charging, QoS for network management purposes, and related information statistics, provided to other servers, systems, network entities, or third parties.
在步骤 85中, PDG向用户发送隧道建立请求成功响应,在该消息中, 将最终协商的 QoS参数发送给 WLAN UE。  In step 85, the PDG sends a tunnel establishment request success response to the user, in which the finally negotiated QoS parameters are sent to the WLAN UE.
在步骤 86中, WLAN UE判断隧道建立请求成功响应中携带的 QoS 参数是否可以接受, 如果是则使用该参数继续业务, 否则 WLAN UE可 以根据默认的配置或用户的选择执行相应的操作, 例如: 断开隧道。 本实施例与第四实施例基本相同, 不同之处仅在于, 本实施例中服 务质量授权模块将 QoS参数通过 AAA服务器发送给任何需要服务质量的 网絡实体中的任何一个, 或其中的任何组合。 而在第四实施例中, 服务 ^量授权模块可以将 QoS参数通过 AAA服务器或者 PDG发送给任何需 要服务质量的网络实体中的任何一个, 或其中的任何组合。 其实, 服务 ^量授权模块通过 PDG发送 QoS参数,或者服务盾量授权模块直接发送 QoS参数的情况都与本实施例的情况类似。 In step 86, the WLAN UE determines whether the QoS parameter carried in the successful response of the tunnel establishment request is acceptable, and if yes, uses the parameter to continue the service, otherwise the WLAN UE may Perform the appropriate action based on the default configuration or user selection, for example: Disconnect the tunnel. This embodiment is basically the same as the fourth embodiment except that the QoS parameter in the embodiment sends the QoS parameter to any one of the network entities requiring quality of service through the AAA server, or any combination thereof. . In the fourth embodiment, however, the service authorization module may send the QoS parameters to any one of the network entities requiring quality of service, or any combination thereof, through the AAA server or PDG. In fact, the case where the service quantity authorization module sends the QoS parameter through the PDG or the service shield quantity authorization module directly transmits the QoS parameter is similar to the case of the embodiment.
虽然通过参照本发明的某些优选实施例, 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。  Although the present invention has been illustrated and described with reference to the preferred embodiments of the present invention, those skilled in the art The spirit and scope of the invention.
