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 802.11g和蓝牙(Bluetooth)技术,其中,802.11g最高数据传输速率可达54Mbps。 Wireless LAN technologies include a variety of different, widely used at present is a technology standard is the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, referred to as "IEEE") developed by IEEE 802.11b, which adopts 2.4GHz frequency band, the maximum data transfer rate of up to 11Mbps, also the use of the band IEEE 802.11g and Bluetooth (Bluetooth) technology, wherein, 802.11g maximum data transfer rate of up to 54Mbps. 其它新技术诸如IEEE 802.11a和ETSI BRAN Hiperlan2都使用5GHz频段,最高传输速率也可达到54Mbps。 Other new technologies, such as IEEE 802.11a and ETSI BRAN Hiperlan2 uses 5GHz frequency band, the maximum transfer rate up to 54Mbps.

随着WLAN技术的兴起和发展,WLAN与各种无线移动通信网,诸如:全球移动通信系统(Global System for mobile Communications,简称“GSM”)、码分多址(Code Division Multiple Access,简称“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access,简称“WCDMA”)系统、时分同步码分多址(Time Division Synchronous Code Division MultipleAccess,简称“TD-SCDMA”)系统、CDMA 2000系统的互通正成为当前研究的重点。 With the rise and development of WLAN technology, WLAN and various wireless mobile communication networks, such as: GSM (Global System for mobile Communications, referred to as "GSM"), CDMA (Code Division Multiple Access, referred to as "CDMA ") system, a wideband CDMA (wideband Code division Multiple Access, referred to as" the WCDMA ") system, TD-SCDMA (Time division synchronous Code division MultipleAccess, abbreviated" TD-SCDMA ") system, CDMA 2000 system interoperability is becoming the focus of current research.

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联而产生的网络。 Interworking WLAN (Interworking WLAN, referred to as "I-WLAN") network and other wireless WLAN mobile communication network interconnection generated. 在第三代合作伙伴项目(3rdGeneration Partnership Project,简称“3GPP”)标准化组织中,用户设备可以通过WLAN的接入网络与因特网、企业内部互联网(Intranet)相连,还可以经由WLAN接入网络与3GPP系统的归属网络或3GPP系统的访问网络连接,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接入网络与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认证授权和计费(AuthenticationAuthorization 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 AccessGateway,简称“WAG”)与3GPP网络中的分组数据网关(Packet DataGateway,简称“PDG”)等等。 In the Third Generation Partnership Project (3rdGeneration Partnership Project, referred to as "3GPP") standardization organization, the user equipment can, intranets (Intranet) connected via WLAN access network and the Internet, you can access the network via WLAN and 3GPP 3GPP home network system or the network connection to access the system, specifically, WLAN user equipment connected with the 3GPP home network via a WLAN access network when local access; while roaming, WLAN access network via the 3GPP connected to a network access, 3GPP visited network entities portion interconnected with a respective entities in the 3GPP home network, for example: 3GPP authentication authorization and accounting (AuthenticationAuthorization and accounting, abbreviated "AAA") 3GPP visited network and 3GPP home agent 3GPP AAA server in the network; 3GPP WLAN access network gateway (WLAN AccessGateway, referred to as "WAG") and 3GPP packet data network gateway (packet DataGateway, referred to as "PDG") and the like.

下面结合图1、图2和图3介绍非漫游和漫游两种状态下I-WLAN的基本模型。 Below in conjunction with FIGS. 1, 2 and 3 describes the basic model of the I-WLAN roaming and non-roaming two states.

图1示出了非漫游状态下的基本模型。 FIG 1 shows a basic model of a non-roaming status. WLAN UE(User Equipment用户设备)接入到WLAN,WLAN还和Internet/Intranet、3GPP归属网络相连,UE可以通过WLAN访问Internet/Intranet或接入3GPP归属网络。 WLAN UE (User Equipment user equipment) access to the WLAN, WLAN and also Internet / Intranet, is connected to 3GPP home network, UE can access the Internet / Intranet access 3GPP home network or via WLAN. 具体地说,WLAN通过Wa接口和3GPP AAA服务器连接、通过Wn接口和WAG连接。 Specifically, WLAN is connected via an interface Wa and 3GPP AAA server, and is connected via an interface Wn WAG. 在3GPP归属网络中,3GPP AAA服务器又分别和签约定位功能(SubscriptionLocator Function,简称“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”)、离线计费系统(Offline Charging System)、在线计费系统(Online ChargingSystem,简称“OCS”)、PDG、WAG相连接。 In the 3GPP home network, 3GPP AAA server and respectively Subscription Locator Function (SubscriptionLocator Function, referred to as the "SLF"), a home subscriber server (Home Subscriber Server, referred to as "HSS"), a home location register (Home Location Register, abbreviated " HLR "), offline charging system (offline charging system), OCS (online ChargingSystem, referred to as" OCS "), PDG, WAG connected. PDG还一方面和WAG连接,一方面和外部网络连接。 PDG further aspect WAG and connected, on the one hand and the external network connection. 在UE和PDG之间可以建立隧道,有了这个隧道,WLAN和WAG对UE和PDG是透明的。 Between the UE and the PDG tunnel may be established, with this tunnel, WLAN and WAG it is transparent to the UE and PDG.

图2示出了一种漫游状态下的基本模型,该模型和非漫游状态的基本模型相比,区别在于WLAN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。 Figure 2 shows a basic model in a roaming state, and the basic model of the model compared to a non-roaming state, except that the WLAN and 3GPP home network is not directly connected, but transit through the 3GPP access network. 具体地说,WLAN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。 Specifically, WLAN interfaces respectively Wa and Wn-3GPP access network interfaces, and the 3GPP AAA proxy, WAG connection. 该WAG和3GPP归属网络中的PDG连接,3PAA代理和3GPP归属网络中的3GPP AAA服务器连接。 The WAG and 3GPP PDG in the home network connected, 3PAA agent in the home network and 3GPP 3GPP AAA server is connected. 同样地,在UE和PDG之间可以建立隧道,有了这个隧道,WLAN和WAG对UE和PDG是透明的。 Similarly, between the UE and the PDG tunnel may be established, with this tunnel, WLAN and WAG are transparent to the UE and PDG.

图3示出了另一种漫游状态下的基本模型,在该模型中,3GPP归属网络中的3GPP AAA服务器与3GPP访问网络中的3GPP AAA代理连接,3GPPAAA代理又分别和WLAN以及3GPP访问网络中的WAG、PDG连接。 FIG 3 shows a basic model of another roaming state, in this model, the home 3GPP network and the 3GPP AAA server in the 3GPP visited network 3GPP AAA proxy connection, respectively, and the 3GPP AAA proxy and the WLAN access network and 3GPP the WAG, PDG connection. 同样地,在UE和PDG之间也可以建立隧道,有了这个隧道,WLAN和WAG对UE和PDG是透明的。 Similarly, between the UE and the PDG can also create a tunnel, with this tunnel, WLAN and WAG are transparent to the UE and PDG.

在上述的模型中,为了向用户提供高质量的基于分组交换的电信服务,就必须要能够保障端到端的服务质量(Quality of Service,简称“QoS”),即在WLAN UE和PDG也要提供QoS保障。 In the above model, in order to provide high-quality telecommunication services to users based on packet switching, it is necessary to be able to guarantee end to end quality of service (Quality of Service, referred to as "QoS"), that is also provided in the WLAN UE and PDG QoS guarantee. 这种QoS保障分为两个层面,一个层面是高层的实体间的QoS协商,使WLAN UE和PDG之间的各个实体对向用户提供的QoS参数达成一致,另一个层面就是在传输时如何实现相应的QoS参数。 This QoS guarantee divided into two levels, one level is a high level of QoS negotiation between the entities so that each entity between the WLAN UE and PDG agree on QoS parameters provided to the user, it is how to achieve another level at the time of transmission corresponding QoS parameters. 目前,在WLAN UE和PDG之间并没有一种明确的机制来提供QoS协商和保障,这样对于很多要求QoS保障的业务,例如IMS业务,就不能很好的支持。 At present, between the WLAN UE and PDG did not provide a clear mechanism for consultation and QoS guarantee, such guarantee QoS requirement for many businesses, such as IMS services, can not be well supported. 对于前一个层面,即QoS协商层面,又包括两个方面:业务建立时的QoS协商和业务进行时QoS修改的处理。 For the previous level, that level of QoS negotiation, also includes two aspects: QoS negotiation processing business and when business is built to perform QoS modification. 本发明的技术方案主要针对后者,即业务进行时QoS修改的处理。 Aspect of the present invention is primarily to the latter, i.e., processing operations for QoS changes.

目前公开的文献中没有I-WLAN中业务进行时QoS修改的方法。 Currently there is no method disclosed in the literature during the I-WLAN traffic for QoS changes.

通过比较可以发现,本发明的主要特点在于,提出了一个修改业务QoS参数的完整流程:由用户设备或网络侧功能实体发起修改流程,PDG、AAA服务器和可选的策略决定功能(Policy Decision Function,简称“PDF”)、应用功能(Application Function,简称“AF”)协商确定授权给用户的QoS参数,再由PDG将其通知用户设备、AAA服务器、WLAN、WAG等隧道相关的实体。 By comparison it found that the main feature of the invention is to propose a complete flow of a service QoS parameters modified: modify the process initiated by the user equipment or the network-side functional entity, PDG, AAA server and optional Policy Decision Function (Policy Decision Function , referred to as "PDF"), application function (application function, referred to as "AF") negotiated QoS parameters granted to the user, and then by the PDG to notify the user equipment, AAA server, WLAN, WAG and other entities related to the tunnel. PDG在通知前还可以和WLAN、WAG协商QoS参数。 PDG prior notice and also WLAN, WAG negotiate QoS parameters. PDG与WLAN、WAG之间的交互通过AAA服务器中转,如果用户设备处于漫游状态,AAA服务器与WLAN、WAG之间的交互还要通过AAA代理的中转。 Between PDG and WLAN, WAG interactive transit through the AAA server, if the user equipment is roaming the interaction between the AAA server and WLAN, WAG also through AAA proxy transit. AAA服务器和AAA代理转发QoS参数时,可以不加修改地转发,也可以根据网络状态、网络侧的设置修改后转发。 When the AAA proxy server and forwards the AAA QoS parameters may be forwarded without modification, may be based on network conditions, provided the modified forwarding network side. 本发明还提出了各种网络侧功能实体触发QoS修改流程的具体条件。 The present invention also provides a network functional entity various QoS modification process specific trigger conditions.

这种技术方案上的区别,带来了较为明显的有益效果,即提出了一套完整的QoS参数修改方案。 Difference in this solution, brings a more significant beneficial effect, namely that a complete set of QoS parameters modifications. 通过发起、授权、协商和发布四个主要步骤,解决了I-WLAN中的QoS修改问题,使得用户设备和各网络侧功能实体(包括WLAN、WAG、AAA服务器、AAA代理、PDG、PDF、AF等)都可以主动发起QoS参数修改流程,通过AAA服务器和AAA代理的协同应用,使本发明对于非漫游和漫游两种状态下的QoS参数修改都可以适用,进而完善了整个互通系统的QoS协商机制。 By initiating, authorizing, consultation and publish four main steps to solve the I-WLAN QoS modification in question, so that each user equipment and network functional entities (including WLAN, WAG, AAA Server, AAA proxy, PDG, PDF, AF etc.) can initiate a QoS parameter modification process, by collaborative applications and AAA proxy AAA server of the present invention for non-QoS parameter modifications roaming and roaming two states can be applied, and thus improve the overall QoS negotiation system interworking mechanism.

先说明一下本发明基本原理。 First explain the basic principles of the invention. 图4示出了本发明的几个基本步骤,下面逐一说明。 FIG 4 shows basic steps of the present invention, described below one by one.

在步骤1中,无线局域网用户设备和分组数据网关之间建立了隧道,业务进行中。 In Step 1, a tunnel is established between a WLAN user equipment and the packet data gateway, service in progress. 因为本发明是针对业务进行中QoS修改的,所以这一步是以下各步骤的前提。 Since the present invention is to modify the QoS for the traffic, so this step is a prerequisite for the following steps. 关于建立隧道时QoS的协商和确定并不是本发明的内容,其具体实现方法可以参见申请号为200510024965.5的中国专利。 Consultation and determine the content of the present invention is not QoS on the establishment of the tunnel, the specific implementation method can be found in Chinese patent application number of 200510024965.5.

此后进入步骤2,无线局域网用户终端或网络侧功能实体发起服务质量参数修改流程。 Then proceeds to Step 2, a user terminal or a wireless LAN network function entity modification process initiated quality of service parameters.

如果服务质量参数最终决策实体是分组数据网关,无线局域网用户设备或网络侧功能实体发起了服务质量参数修改流程,在服务质量参数修改请求中,发起修改流程的实体需要根据自身的能力和负载情况等,告知分组数据网关其要求的服务质量参数。 If the quality of service parameters final decision entity is a packet data gateway, the wireless LAN user equipment or the network-side functional entity initiated quality of service parameter modification process, the quality of service parameter modification request, the initiating entity modification process requires its own capability and load etc., quality of service parameters to inform a packet data gateway their requirements. 在该步骤中,不同的发起设备会有不同的发起方式:如果是无线局域网用户设备发起服务质量参数修改流程,则服务质量参数修改请求是发送给分组数据网关;如果是无线局域网发起服务质量参数修改流程,则服务质量参数修改请求是通过认证授权和计费服务器发送给分组数据网关;如果是无线局域网接入网关发起服务质量参数修改流程,则服务质量参数修改请求是通过认证授权和计费服务器发送给分组数据网关;如果是认证授权和计费服务器发起服务质量参数修改流程,则服务质量参数修改请求直接发送给分组数据网关;如果是策略决定功能或应用功能发起服务质量参数修改流程,则不需要将服务质量参数修改请求发送给分组数据网关,而是直接执行下面的步骤3,即直接将授权的服务质量参数发送给分组数据网关。 In this step, different devices have different initiating initiates ways: If a WLAN user equipment initiates a service quality parameter modification process, the quality of service parameter modification request is sent to the packet data gateway; if the wireless LAN is initiated quality of service parameters modify the process, the quality of service parameter modification request is authenticated authorization and accounting server to a packet data gateway; if the wireless LAN access gateway initiated modification procedure quality of service parameters, the quality of service parameter modification request is authenticated authorization and accounting the server sends to the packet data gateway; if authentication authorization and accounting server is initiated quality of service parameter modification process, the quality of service parameter modification request is sent directly to the packet data gateway; if it is a policy decision function or application function initiated quality of service parameters to modify the process, then no quality of service parameter modification request to a packet data gateway, but directly performs the following three steps, i.e., will send an authorized quality of service parameters to the packet data gateway.

如果服务质量参数最终决策实体是认证、授权和计费服务器,无线局域网用户设备或网络侧功能实体发起了服务质量参数修改流程,在服务质量参数修改请求中,发起修改流程的实体需要根据自身的能力和负载情况等,告知认证、授权和计费服务器其要求的服务质量参数。 If the quality of service parameters is the ultimate decision-making entity authentication, authorization and accounting server, wireless LAN user equipment or the network side of the functional entity to initiate a quality of service parameter modification process modification request in the quality of service parameters, to modify the process of initiating entity needs according to their own and the ability to load and so on, informing authentication, authorization and accounting server of its required quality of service parameters. 在该步骤中,不同的发起设备会有不同的发起方式:如果是无线局域网、无线局域网接入网关和分组数据网关发起服务质量参数修改流程,则服务质量参数修改请求直接发送给认证、授权和计费服务器;如果是无线局域网用户终端、策略决策功能或应用功能发起服务质量参数修改流程,则需要将服务质量参数修改请求发送给分组数据网关,再由分组数据网关发送给认证、授权和计费服务器。 In this step, different devices have different initiating initiated: If the wireless local area network, wireless LAN access gateway and the packet data gateway modification procedure initiated quality of service parameters, the quality of service parameter modification request sent directly to authentication, authorization, and billing server; if the user terminal is a wireless local area network, a policy decision function or application function initiated quality of service parameter modification process, you will need to modify the parameters of quality of service request to the packet data gateway, and then sent by the packet data gateway for authentication, authorization, and fee server. 分组数据网关发送给认证、授权和计费服务器之前可以做适应性修改。 Packet data gateway can be done before the adaptations to the authentication, authorization and accounting server.

下面介绍各种发起设备可能发起服务质量参数修改流程的触发条件:无线局域网用户设备发起服务质量参数修改流程,可能的触发条件包括但不限于:无线局域网用户设备在不同能力的无线局域网间发生切换,例如从IEEE802.11b网络切换到IEEE 802.11g网络;用户的业务在不同的无线局域网用户设备间发生切换;隧道对应的业务的服务质量要求发生了变化。 The following describes the various devices may initiate a modification process initiated quality of service parameters trigger condition: WLAN UE initiates the process to modify quality of service parameters, trigger conditions may include, but are not limited to: wireless LAN user equipment handover occurs between different wireless LAN capabilities , such as from the network to the IEEE 802.11g network IEEE802.11b; user service switching occurs between different WLAN user equipment; tunnel corresponding to the quality requirement of the service changes.

无线局域网接入网关发起服务质量参数修改流程,可能的触发条件包括但不限于:无线局域网接入网关状态发生变化,能够提供或保证的服务质量参数发生了变化,例如,网络负载发生变化,可用资源发生变化等;根据网络侧的配置,或来自运营维护系统的指令,修改提供给用户的服务质量;无线局域网接入网关检测到隧道数据包没有对应的服务质量参数,例如:发现带有某个特定隧道标识的数据包没有对应的服务质量参数部署在无线局域网接入网关。 Wireless LAN access gateway initiated quality of service parameter modification procedure, trigger conditions may include, but are not limited to: wireless LAN access gateway state changes, or capable of providing guaranteed quality of service parameter changes, e.g., changes in network load, available changes in resource; depending on the configuration of the network, or an instruction from the operation and maintenance system, modifying the quality of service provided to the user; wireless LAN access gateway detects a tunnel packet does not correspond to quality of service parameters, such as: having found a identifying a particular tunnel packet does not correspond to quality of service parameters deployed in a wireless LAN access gateway.

分组数据网关发起服务质量参数修改流程,可能的触发条件包括但不限于: Packet data gateway initiated quality of service parameters modification procedure, trigger conditions may include, but are not limited to:

分组数据网关状态发生变化,能够提供或保证的服务质量参数发生了变化,例如,网络负载发生变化,可用资源发生变化等;根据网络侧的配置,或来自运营维护系统的指令,修改提供给用户的服务质量;分组数据网关检测到隧道数据包没有对应的服务质量参数,例如:发现带有某个特定隧道标识的数据包没有对应的服务质量参数;分组数据网关接受到来自外部网络服务器的要求,或检测到来自外部网络的业务的服务质量发生了变化。 Packet data gateway state changes, it is possible to provide or ensure the quality of service parameter changes, e.g., the network load changes, the available resource varies like; depending on the configuration the network side, or an instruction from the operation and maintenance system, modifications to the user quality of service; packet data gateway detects a tunnel packet does not correspond to quality of service parameters, for example: found packet with a particular tunnel identifier does not correspond to quality of service parameters; packet data gateway receives requests from the external network server or detected traffic from the external network quality of service has changed.

认证授权和计费服务器发起服务质量参数修改流程,可能的触发条件包括但不限于:由于用户的签约信息等发生改变;用户的计费状态发生变化;根据网络侧的配置,或来自运营维护系统的指令,修改提供给用户的服务质量。 Authentication Authorization and Accounting server initiated quality of service parameter modification procedure, trigger conditions may include, but are not limited to: changes due to the subscription information of the user and the like; user accounting status change; depending on the configuration of the network side, or from the operation and maintenance system instructions to modify the quality of service provided to users.

应用功能发起服务质量参数修改流程,可能的触发条件包括但不限于:在会话控制级别发生了会话/业务修改;根据网络侧的配置,或来自运营维护系统的指令,修改提供给用户的服务质量。 Application function initiated quality of service parameter modification procedure may trigger conditions include, but are not limited to: a session control level if a session / service modification; The configuration of the network side, or an instruction from the operation and maintenance system, to modify the quality of service provided to the user .

此后进入步骤3,分组数据网关和认证授权和计费服务器,可能还有策略决定功能和应用功能,通过协商确定授权给用户终端的服务质量参数(修改后的服务质量参数)。 Since then proceed to step 3, the packet data gateway and authentication authorization and accounting server, there may be a policy decision function and application function, determined by negotiation granted to the quality of service parameters (quality of service parameters modified) user terminals.

如果是分组数据网关最终决定授权给用户终端的服务质量参数,在确定授权给用户终端的服务质量参数(修改后的服务质量参数)时,分组数据网关自身的能力和负载情况也需要考虑在内。 If the final decision is a packet data gateway to the quality of service parameters authorized user of the terminal, in determining the authorized user terminal to quality of service parameters (quality of service parameters modified), Packet Data Gateway own ability and load conditions need to be considered . 分组数据网关和认证授权和计费服务器之间的授权负责的是无线局域网用户设备和分组数据网关之间承载的服务质量的授权和限制,例如带宽、时延等;分组数据网关、策略决定功能和应用功能间的交互是业务/会话层面的协商交互和授权,例如服务质量类别、带宽等,同时策略决定功能需要将业务/会话层面的服务质量信息映射到承载层的服务质量参数并传递给分组数据网关。 Packet data entrusted with the responsibility between the gateway and authentication authorization and accounting server is carried between the wireless LAN user equipment and the packet data gateway of quality of service authorization and restrictions, such as bandwidth and delay; packet data gateway, a Policy Decision Function and inter-application function interactions are business / session-level consultations interaction and authorization, such as quality of service class, bandwidth, while policy decision function needs to map business / session-level quality of service information to the quality of service parameters bearing layer and passed to packet data gateway.

如果任何一个网络实体发来的服务质量修改要求中携带的服务质量要求,和认证授权和计费服务器中存贮的无线局域网用户的服务质量信息不兼容(例如不符合该用户签约的服务质量),或是和当前的隧道的属性存在冲突,分组数据网关会返回拒绝服务质量修改消息(该消息内可能会包括拒绝的原因)。 If any network entity sent by the quality of service required modifications carried in quality of service requirements, and authentication, authorization and accounting server stored in the wireless LAN user quality of service information is not compatible (for example, does not meet the quality of service the user has subscribed) , and the current or the properties of the tunnel there is a conflict, reject the packet data gateway returns the quality of service modification message (reasons may include the rejection of the message).

如果是认证、授权和计费服务器最终决定授权给用户终端的服务质量参数,则认证、授权和计费服务器会比较其存储的无线局域网用户的服务质量信息和任何一个网络实体发来的服务质量修改要求中携带的服务质量要求,若存在不兼容的情况(例如不符合该用户签约的服务质量),认证、授权和计费服务器会返回拒绝服务质量修改消息(该消息内可能会包括拒绝的原因)。 If authentication, authorization and accounting server to the final decision to authorize the quality of service parameter of the user terminal, the authentication, authorization and accounting server compares its stored wireless LAN user quality of service information and any entity sent by a network quality of service amendment request carried in quality of service requirements, if the situation is not compatible with the existence (such as the user does not meet the quality of service contract), authentication, authorization and accounting server will return a message to modify the quality of service denial (denial may include within the message the reason). 如果是向无线局域网、无线局域网接入网关和分组数据网关返回拒绝服务质量修改消息,则消息是直接由认证、授权和计费服务器返回给相应的实体;如果是向无线局域网用户终端、策略决策功能或应用功能返回拒绝服务质量修改消息,则消息是由认证、授权和计费服务器返回给分组数据网关,再由分组数据网关返回给相应的实体。 If the wireless LAN, wireless LAN access gateway and the packet data gateway returns a rejection message to modify the quality of service, the message is directly returned by the authentication, authorization and accounting server to the corresponding entity; if it is the WLAN user terminal, the policy decision function or application function returns the modified message to refuse service quality, then the message is returned by the authentication, authorization and accounting server to the packet data gateway, the packet data gateway and then returned to the respective entity.

发起服务质量修改请求的实体如果收到拒绝消息,后续的操作包括但不限于以下方法:不修改服务质量,维持现在的服务质量;断开业务/隧道连接; Initiating quality of service modification request entity if receipt of the rejection message, subsequent operations include but are not limited to the following: does not modify the quality of service, to maintain the current quality of service; disconnect service / tunnel connection;

根据网络侧的配置执行相应的操作,等等。 Performing a corresponding operation according to the configuration of the network, and the like.

此后进入步骤4,该步骤是可选的。 Thereafter proceeds to step 4, this step is optional. 如果是分组数据网关最终决定授权给用户终端的服务质量参数那么分组数据网关以认证授权和计费服务器为中介,以步骤3中确定的授权的服务质量参数为基础,分组数据网关与无线局域网、无线局域网接入网关和无线局域网用户设备进行服务质量参数协商,获得一个各个网络实体都能提供的服务质量参数。 If the final packet data gateway is authorized to decide the quality of service parameters of the user terminal, then the data packet to the gateway server authentication authorization and accounting intermediary authorized quality of service parameter is determined in step 3 is based, a packet data gateway and a wireless LAN, wireless LAN and wireless LAN access gateway device user quality of service parameter negotiation, access to a quality of service parameters of each network entity can provide. 如果是认证、授权和计费服务器最终决定授权给用户终端的服务质量参数,那么认证、授权和计费服务器以步骤3中确定的授权的服务质量参数为基础,与分组数据网关、无线局域网、无线局域网接入网关和无线局域网用户终端进行服务质量参数协商,获得一个各个网络实体都能提供的服务质量参数。 If an authentication, authorization and accounting server to the final decision to authorize the Quality of Service parameter of the user terminal, then the quality of service parameters authorized authentication, authorization and accounting server in step 3 is determined on the basis, the packet data gateway, wireless LAN, WLAN access gateway and wireless LAN user terminals quality of service parameter negotiation, access to a quality of service parameters of each network entity can provide. 此后进入步骤5,服务质量参数通知。 Since then proceed to step 5, notice the quality of service parameters.

接着,进入步骤5。 Next, the routine proceeds to step 5. 如果是分组数据网关最终决定授权给用户终端的服务质量参数,那么分组数据网关将授权的服务质量参数通知给无线局域网、无线局域网接入网关和无线局域网用户设备。 If the final packet data gateway is authorized to decide the quality of service parameters of the user terminal, the packet data gateway authorized quality of service parameters to the radio LAN, wireless LAN and wireless LAN access gateway user equipment. 如果在该步骤之前执行了步骤4,则分组数据网关是将协商出的服务质量参数通知给无线局域网和无线局域网接入网关。 If the performance of step 4, the packet data gateway is the negotiated quality of service parameters prior to the step of notifying the wireless LAN and the wireless LAN access gateway. 如果某个网络实体不能接受授权的服务质量参数,或不能提供授权的服务质量参数,则根据网络侧的配置,提供降低的服务质量参数,或发起断开连接流程,或保持现有的服务质量。 If a network entity unacceptable quality of service parameters authorized or not authorized to provide quality of service parameters, depending on the configuration of the network side, to provide a reduced quality of service parameters, or initiate disconnect procedure, or maintain the existing quality of service . 分组数据网关通过认证授权和计费服务器发送服务质量参数通知时,认证授权和计费服务器对服务质量参数的转发有两种方式:一种是不做任何修改直接发送给无线局域网和无线局域网接入网关;另一种是根据网络的状态、网络侧的配置等条件,对服务质量参数作适应性修改后再发送给无线局域网和无线局域网接入网关。 When the packet data gateway sends a notification quality of service parameters and accounting server authentication and authorization, authentication, authorization and accounting server to forward the quality of service parameters in two ways: one is sent directly without any modification to the wireless LAN and wireless LAN access the gateway; the other is the state of the network, the network side is configured like conditions, quality of service parameters for the adaptation and then to a wireless LAN and wireless LAN access gateway. 网络的状态的包括但不限于:当前用户数,当前负载,已用存储器容量,已用处理器容量,已用端口数,可用存储器容量,可用处理器容量,可用端口数等。 State networks include, but are not limited to: the number of current users, current load, the used memory capacity, processor capacity has been used, has a number of ports, the available memory capacity, processor capacity is available, and so the number of available ports.

认证授权和计费服务器需要存储这些服务质量参数,用于特定目的,例如计费的依据、用于网管目的的服务质量和相关信息统计、提供给其它服务器、系统、网络实体或第三方等等。 Authentication, authorization and accounting server needs to store these quality of service parameters for a specific purpose, such as billing basis, for the purpose of network management and service quality statistical information available to other servers, system, network entity or a third party, etc. .

如果是认证、授权和计费服务器最终决定授权给用户终端的服务质量参数,认证、授权和计费服务器将授权的服务质量参数通知给分组数据网关、无线局域网、无线局域网接入网关和无线局域网用户终端。 If an authentication, authorization and accounting server to the user terminal decides to authorize the final quality of service parameters, authentication, authorization, and accounting server notifies the authorized quality of service parameters to the packet data gateway, wireless LAN, wireless LAN and wireless LAN access gateway user terminal. 如果在该步骤之前执行了步骤4,则分认证、授权和计费服务器是将协商出的服务质量参数通知给无线局域网和无线局域网接入网关。 If step 4 is performed prior to this step, the sub-authentication, authorization and accounting server is the negotiated quality of service parameter notification to the wireless LAN and wireless LAN access gateway. 如果某个网络实体不能接受授权的服务质量参数,或不能提供授权的服务质量参数,则根据网络侧的配置,提供降低的服务质量参数,或发起断开连接流程,也可能是保持现有的服务质量。 If a network entity unacceptable quality of service parameters authorized or not authorized to provide quality of service parameters, depending on the configuration of the network side, to provide a reduced quality of service parameters, or initiate disconnect procedure, it may be to maintain the existing service quality.

认证授权和计费服务器需要存储这些服务质量参数,用于特定目的,例如计费的依据、用于网管目的的服务质量和相关信息统计、提供给其它服务器、系统、网络实体或第三方等等。 Authentication, authorization and accounting server needs to store these quality of service parameters for a specific purpose, such as billing basis, for the purpose of network management and service quality statistical information available to other servers, system, network entity or a third party, etc. .

以上各步骤是在非漫游情况下的,如果用户在漫游情况下,服务质量参数修改请求的发送,服务质量参数的协商,服务质量参数的通知等还需要通过认证授权和计费代理的转发。 In the above steps are non-roaming case, if the user in case of roaming, quality of service parameters to modify send, quality of service parameters requested consultations, notification services and other quality parameters required by the certification authorization and accounting proxy forwarding.

在漫游情况下,分组数据网关通过认证授权和计费代理发送服务质量参数通知时,认证授权和计费代理对服务质量参数的转发有两种方式:一种是不做任何修改直接发送给无线局域网和无线局域网接入网关;另一种是根据访问网络的状态、访问网网络侧的配置等条件,对服务质量参数作适应性修改。 In the case of roaming, when the notification parameters packet data gateway through quality authentication, authorization and accounting proxy delivery service, authentication, authorization and accounting proxy forwarding service quality parameters in two ways: one is sent directly without any modification to the wireless LAN and wireless LAN access gateway; the other is the state of the network access, like the configuration of the network visited network conditions, quality of service parameters for adaptation. 网络的状态的包括但不限于:当前用户数,当前负载,已用存储器容量,已用处理器容量,已用端口数,可用存储器容量,可用处理器容量,可用端口数等。 State networks include, but are not limited to: the number of current users, current load, the used memory capacity, processor capacity has been used, has a number of ports, the available memory capacity, processor capacity is available, and so the number of available ports.

在漫游情况下,如果需要,认证授权和计费服务器也可以存储这些服务质量参数,用于特定目的,例如计费的依据、用于网管目的的服务质量和相关信息统计、提供给其它服务器、系统、网络实体或第三方等等。 In the case of roaming, if required, authentication, authorization and accounting server can also store the quality of service parameters for a specific purpose, such as billing basis, for the purpose of network management and service quality statistical information available to other servers, system, network entity or a third party, and so on.

上面说明了本发明原理,下面在多个实施例中具体说明I-WLAN中QoS的修改方法。 The above described principles of the invention, the following examples specifically described modification method in I-WLAN QoS in a plurality of embodiments.

实施例1:无线局域网用户设备发起QoS修改(由分组数据网关最终确定授权给用户终端的服务质量参数),如图5所示。 Example 1: WLAN UE initiates QoS modification (determined by the packet data gateway ultimately authorized quality of service parameters to the user terminal), as shown in FIG.

步骤1,WLAN UE和PDG之间建立了隧道,业务进行中;步骤2,WLAN UE向PDG发起QoS修改请求;步骤3,AAA服务器上存储着WLAN用户的签约信息,其中包括QoS信息,PDG和AAA服务器之间就QoS参数进行授权,对提供给用户的QoS参数进行授权;步骤4,如果互通系统支持策略控制框架(即互通系统可以与PDF和AF交互)则还存在PDG、PDF和AF之间就QoS参数等信息进行的授权、指示等步骤,这里暂时略去,在实施例6中详细说明;步骤5,PDG通过AAA服务器将修改后的QoS参数通知给WLAN AN和WAG。 Step 1, is established between WLAN UE and the PDG tunnel, the service performed; Step 2, WLAN UE initiates QoS modification request to the PDG; step 3, the WLAN user stored on the AAA server subscription information, including QoS information, and PDG between the AAA server carry out QoS parameter authorization of QoS parameters to the authorized user; step 4, if the system supports interworking policy control framework (i.e. interworking system and AF may interact with the PDF) there is also present the PDG, PDF, and the AF between authorized QoS parameters to the information, instructions and other steps, temporarily omitted here described in detail in Example 6; step 5, PDG modified QoS parameters to the WLAN AN, and notifies the AAA server through WAG. 同时,AAA服务器存储QoS参数。 Meanwhile, AAA server stores QoS parameters. 在漫游情况下,QoS参数的通知还需要通过AAA代理转发,根据需要,AAA代理可以对QoS参数做适应性修改,或者不做任何修改,同时,AAA代理也可能存储QoS参数。 In the case of roaming, QoS parameters need to inform through AAA proxy forwards, if necessary, AAA proxy can be done adaptation of the QoS parameters, or without making any changes, while, AAA proxy may store QoS parameters. 另外,根据网络实体的能力,以及网络侧的配置,QoS参数也可能只通知部分网络实体,例如只通知WLAN AN,或只通知WAG,或只通知WLAN AN和WAG。 Further, according to the configuration capabilities of the network entity, and the network side, QoS parameters may notify only part of the network entity, for example, only inform WLAN AN, or only notify WAG, or only notify WLAN AN and WAG.

步骤6,PDG向WLAN UE发送QoS修改请求应答。 Step 6, PDG sends a WLAN UE QoS modification request response.
