如图 1所示, 所述的业务层由 NASS (网络附件子系统, The Network Attachment Subsystem )、 RACS(资源和准入控制子系统, The Resource and Admission Control Subsystem ) 、 IMS ( IP多媒体子系统, The IP Multimedia Subsystem )、 PES( PSTN/ISDN仿真子系统, The PSTN/ISDN Emulation Subsystem ) 、 其他多媒体子系统和应用、 以及这些子系统的 通用业务部件组成, 所述的通用业务部件包括应用服务器、 计费功能、 用 户配置文件管理、 安全管理等等。
在 NASS和 RACS的控制下, 传送层提供 NGN终端间的 IP连接, 隐藏 了接入和核心网 IP层以下所使用的传送技术。 这些子系统可能分布在网络 /业务提供商的管理域中。
NGN环境中支持端到端 QoS (服务质量)控制的一个关键部件是 RACS。 RACS在 NGN总体框架中的位置及其外部接口关系如图 2所示。资 源和准入控制子系统需要与传送层、 用户驻地设备、 网络附件子系统、 IP 多媒体子系统、 PSTN/ISDN仿真子系统、其他业务子系统、 以及其他网络 中的 RACS有接口关系。 RACS提供准入控制功能, 所述的准入控制包括 基于网絡附件子系统所保存的用户配置文件检查资源可用性。检查资源可 用性意味着准入控制控制核实所请求的带宽是否符合用户订购带宽和已 用带宽。
由于 NGN业务的多样性和多媒体特点,如何使基于 IP的传送层能够实 现针对用户业务的 QoS控制成为了 NGN技术研究中的重要课题。 为此, IETF (互联网工程任务组)提出了 IntServ/RSVP (集成服务 /资源预留协 议) 、 DiffServ (差分服务)及其策略控制模型和机制。
在 IETF提出的 IntServ/RSVP及其策略控制模型中,以及目前正在制定 的 NSIS (下一步 IP信令)草案中, 如图 3所示, 用户可以通过专用资源预 留信令向网络传递 QoS参数, 请求所希望的 QoS保证级别。 由于 RSVP或 NSIS都运行在传送层,与数据流走相同的路由和路径, 因此, 要求用户驻 地设备必须支持 RSVP或 NSIS协议, 能够向网络发出显式 QoS请求。 这种 保证 QoS的方法对于没有能力向网络显式发起 QoS请求的用户是不适用 的。
而在实际应用过程中, 即在当前网络环境中, 绝大多数 CPE (用户驻 地设备)即用户均不支持 RSVP/NSIS协议。 而且, 即使新的用户终端逐渐 支持 RSVP/NSIS协议, 在网络端还需要提供满足用户的业务流量的 QoS 需求。 而在网络端的 PDF (策略决策功能)进行准入控制和门控制时只基 于用户配置文件和运营商管理策略规则, 没有基于资源状态检查网絡资源 的可用性, 因而也就无法根据网絡的情况提供有保证的 QoS。
在 IETF还提出了 DiffServ及其策略控制模型,如图 4所示。具体为由用 户向网络请求和协商 QoS, 所釆用的方法有两种:
一种方法是用户驻地设备对用户报文进行流量分类、 Diffserv标记、 监管和整形, 网络设备信任用户报文中的 DiffServ标记, 进行 Diffserv转发 处理。
另一种方法是用户与网络运营商之间通过管理途径签订 SLA( Service Level Agreement, 服务等级协定), 包含用户流量所需的带宽和 DiffServ 类型等 QoS参数。 网络管理系统通过策略控制接口或者网管接口将用户要 求的 QoS参数静态配置在网络边缘设备上。 网络边缘设备 ^据 QoS配置对 用户报文进行流量分类、 DiffServ标记、 监管和整形, 网络中的设备根据 边缘设备在报文中所做 DiffServ标记, 进行 DiffServ转发处理。 在 IETF提出的 DiffServ及其策略控制模型中, 用户与网絡在管理平面 上进行 QoS协商。 用户的 QoS请求在网络中由报文中的 DiffServ标记值表 示, 由于 DiffServ标记只有 3比特, 只能体现包括 QoS等级和优先级的相对 需求, 无法端到端地传递用户所希望的 QoS参数, 包括带宽、 延时、 抖动 和丢包率等, 用户流量从网络只能得到相对 QoS区分处理。 且同样无法基 于网络资源的可用性实现对用户业务的 QoS的保证。
综上所述, 可以看出, IETF提出的 IntServ/RSVP (集成服务 /资源预 留协议)、 DiffServ (差分服务)及其策略控制模型和机制无法在 NGN网 络中提供承载层 UNK用户网络接口)到 UNI之间数据流路径(即端到端) 的 QoS保证, 不能满足 NGN中业务多样性、技术多样性和终端多样性的 要求。

图 5至图 9为本发明所述的方法的具体实现流程图。
具体实施方式 本发明的核心思想是由资源和准入控制子系统获取用户驻地设备开 展业务需要提供的 QoS参数信息, 并由资源和准入控制子系统根据所述的 QoS参数信息及资源可用性信息等确定相应的准入控制参数, 最后由业务 传送功能模块执行所述的准入控制参数对所述业务的媒体流进行相应处 理和传送。 从而实现了针对网络中传输的业务的 QoS提供相应的保证。 本发明中, 由于 NGN中接入技术和用户驻地设备的多样性, 首先必须 要研究具有不同智能的釆用不同接入技术的用户终端如何向网络动态请 求和协商 QoS的方法, 并考虑支持不同的商业模型。 其次, 由于 NGN中各 个管理域可能采用不同的 QoS技术和商业模型, 必须要研究考虑如何支持 用户业务流量的 QoS需求穿越不同管理域和不同 QoS技术域的问题。
为此, 本发明首先提供了一种下一代网络中动态协商服务质量的系 统, 所述的系统的组成结构可以参照图 5所示, 具体包括:
资源和准入控制子系统: 获取下一代网络中传输的业务需要的服务质 量参数信息, 根据所述的服务质量参数信息确定准入控制参数, 并将所述 的准入控制参数发送给传送功能模块;
所述的资源和准入控制子系统主要是通过业务控制功能模块获取所 述的 QoS参数信息; 当然, 还可以通过 NASS获取所述的 QoS参数信息, 或者, 还可以通过传送功能模块获取所述的 QoS参数信息。
传送功能模块: 获取资源和准入控制子系统发来的准入控制参数, 执 行所述的准入控制参数实现下一代网络中传输的业务的 QoS。
业务控制功能模块: 与用户终端通信, 直接或间接地获取用户终端开 展的业务需要的 QoS参数信息, 并将所述的 QoS参数信息发送给所述的资 源和准入控制子系统;
当用户终端开展业务时, 首先需要向业务控制功能模块部分发起请 求, 所述的请求中可以携带着该业务需要的 QoS参数信息; 业务控制功能 模块还可以通过用户终端与对端用户或应用服务器协商获得该业务的 QoS参数信息; 另外, 业务控制功能模块还可以根据用户终端开展的业务 的类型确定相应的 QoS参数信息。
网络附件子系统: 分别与资源和准入控制子系统及业务控制功能模块 通信, 为资源和准入控制子系统提供所述业务相关的用户配置文件信息。
本发明基于 NGN的资源和准入控制子系统及其外部接口关系, 提供了 NGN环境中用户 (即 CPE )向网絡请求和协商 QoS的框架及方法, 通过用 户与网络的交互以及网络业务层与传送层的交互, 支持不同能力的用户终 端和多种商业模式下的 QoS服务。 基于上述系统,本发明还提供了一种 NGN环境中用户向网络申请和协 商 QoS的处理流程。 如图 5所示, SCF (业务控制功能)模块负责各业务 子系统中的业务建立、控制和终止的功能,如在 IP多媒体子系统中的 CSCF (呼叫会话控制功能)。 本发明中, 采用用户驻地设备与业务控制功能模 块或 TF (传送功能)模块交互, 传递 QoS请求和确认信息, 并由 RACS负 责业务控制功能模块与传送功能模块之间关于 QoS支持的交互和协商, 实 现端到端 QoS控制, 满足用户的 QoS请求。
本发明中, 为了实现基于资源使用的计费, 业务控制功能模块、 资源 和准入控制子系统需要与传送功能模块交互, 对用户业务收集用于计费的 资源使用信息。
本发明可以支持具有不同能力的用户终端和多种商业模式。
才艮据 QoS协商能力的不同可以将用户终端分为以下四种:
1、 无法通过信令方式发出显式 QoS请求的用户终端。
2、 支持以 RSVP或 NSIS等专用 QoS信令发起资源预留请求的用户终 端;
3、 支持在 SIP/SDP (会话起始协议 /会话描述协议)等业务信令中协 商 QoS需求的用户终端;
4、 支持业务信令和专用 QoS信令相互配合协商 QoS的用户终端。
居 QoS区分级别, 所述的商业模式可以划分为三种:
1、 应用流级的 QoS区分: 在每次业务的数据流开始前, 用户需要为 该流向网络发出明确的 QoS请求, 该流在网络中受到用户 QoS请求中所期 望的 QoS待遇, 不同数据流在网络中可能受到不同的 QoS待遇;
2、 业务类级的 QoS区分: 用户不需要显式发出 QoS请求, 业务类型 隐含着该类业务的 QoS需求, 网络负责根据业务类型确定业务流量所需要 的 QoS待遇, 不同类型业务的流量可能受到不同的 QoS待遇;
3、用户级的 QoS区分:根据用户与运营商签订服务等级协议,如 SLA 等, 用户的业务流量在网络中受到 SLA中所期望的 QoS待遇, 不同用户的 业务流量在网络中可能受到不同的 QoS待遇。 本发明针对上述具有不同能力的用户终端及商业模式提供了几种基 本原理相同但具体实现方式不同的 QoS请求和协商处理流程, 运营商可以 根据用户终端的能力和希望的商业模式选择适合的 QoS请求和协商处理 流程。 首先对本发明所述的方法的基本原理进行说明:
用户驻地设备开展需要提供相应的 QoS保证的业务时, NGN中的 RACS获取相应的 QoS请求信息, 并由 RACS对该业务的 QoS请求信息进 行鉴权和准入控制处理。由于在 RACS中可以了解网络中的资源使用情况, 以及网络的性能状况等一些网络状况信息, 从而可以根据网络的实际情况 确定为相应的业务提供最合理的 QoS保证。 现再结合附图对本发明所述的方法的具体实施方式进行说明。 各具体 实施方式包括根据不同能力的用户终端及商业模式分别实现的 QoS请求 和协商处理流程, 下面将举几例分别对所述的 QoS请求和协商处理流程进 行说明。
1、 当所述的商业模式为业务类级的 QoS区分时, 用户的业务类型将 隐含着该业务的 QoS需求, 并由业务控制功能模块或信令网关根据用户的 业务类型代理用户发起 QoS请求。
相应的具体的 QoS请求和协商处理流程, 即相应的动态 QoS协商处理 流程如图 5所示, 包括:
步骤 51 : 用户向网络发起业务请求, 如呼叫建立请求, 业务请求中无 需明确包含用户对此次业务的 QoS需求参数;
步驟 52: 业务控制功能模块或信令网关收到用户业务请求后, 根据业 务类型确定此次业务所需 QoS参数, 所述的 QoS参数包括: 本次业务需要 的带宽, 以及允许的延时、 抖动、 丢包率等;
同时, 所述的业务控制功能模块或信令网关还需要代理用户向 RACS 发出此次业务的 QoS请求, 请求中包含着确定的 QoS参数信息;
当然, 如果一次业务包含多个数据流, 则在业务控制功能模块或信令 网关处需要针对每个数据流分别确定其 QoS参数并发出相应的 QoS请求; 步驟 53: RACS收到所述的 QoS请求后, 基于用户配置文件、 运营商 特定策略规则以及资源可用性等, 对收到的 QoS请求进行鉴权和准入控 制, 确定相应的准入控制参数;
具体为: RACS收到 QoS请求后, 需要获取用户配置文件及运营商特 定策略规则, 如: 所述用户的身份信息、 服务等级协定信息、 与其对应的 网络配置信息等; 同时, RACS还需要检查当前网络资源可用性, 如: 网 络中用户数据流路径上的空闲带宽资源、 已用带宽资源、 网络性能等情况 信息; 获取了上述信息后 RACS便可以根据获取的资源可用性信息对所述 业务的 QoS请求进行鉴权和准入控制处理;
并且, 当 RACS确定允许所述业务按照要求的 QoS参数在网络中传输 时, 则对位于网络边缘的传送功能模块的流量转发行为发出门控制( Gate Control ) 、 带宽分配、 DSCP (区分服务码点 )标记 ( DSCP marking ) 、 聚合和适配控制 ( Aggregation and adaptation control )命令等准入控制 参数信息。
步骤 51到步骤 53所提供的 QoS请求和协商流程尤其适合用于针对语 音业务和筒单终端的处理。
2、 当用户终端支持通过 SIP/SDP等业务信令向网络业务层发起明确 的 QoS请求时, 具体的动态 QoS协商处理流程如图 6所示, 包括:
所述用户终端首先需要向网络发起业务请求, 如呼叫建立请求, 在业 务建立过程中, 可以通过业务层信令(如: SIP的会话描述协议或者 H.323 的能力交换协议等)与对端用户或应用服务器协商此次业务需要的 QoS参 数, 具体的协商处理过程可以与现有技术相同, 本发明对此不作限定; 如果一次业务包含多个数据流, 则需要针对每个数据流分别协商其相 应的 QoS参数。
步骤 61 : 用户终端经过协商获取到所述的 QoS参数后, 则携带着所述 的 QoS参数向业务控制功能模块部分发送业务请求消息;
步骤 62: 业务控制功能模块收到用户业务请求后, 提取出其中所协商 的 QoS参数, 然后向 RACS转发此次业务的 QoS请求;
步骤 63: RACS基于用户配置文件、 运营商特定策略规则和资源可用 性, 对收到的 QoS请求进行鉴权和准入控制处理; 并在确定允许所述业务 按照要求的 QoS参数在网络中传输的情况下 , 对位于网络边缘的传送功能 模块的流量转发行为发出门控制、 带宽分配、 DSCP标记控制、 聚合和适 配控制命令等等。
步骤 61至步骤 63的 QoS请求和协议处理流程比较适合用于针对多媒 体业务和终端的处理。
3、 用户终端通过路径解耦式专用 QoS信令向网络业务层发起明确的 QoS请求; 所述的路径解耦式 QoS信令, 是指 QoS信令路径与其所服务的 用户数据流路径无关。
在这种情况下, 具体的动态 QoS协商处理流程如图 7所示, 包括: 步骤 71 : 用户通过路径解耦式专用 QoS信令, 为某次或某项需要 QoS 保证的数据业务向网络业务层 (即业务控制功能模块)发起明确的 QoS请 求, 所述的 QoS请求中包含数据业务流的标识信息, 如: 数据流的源、 目 的地址和端口及协议类型等信息;
步骤 72: 业务控制功能模块收到 QoS请求后, 根据数据业务流的标识 信息对该数据业务进行鉴权, 并在鉴权通过后向 RACS转发此次业务的 QoS请求;
步骤 73: RACS收到所述的 QoS请求消息后, 基于用户配置文件、 运 营商特定策略规则和资源可用性, 对收到的 QoS请求进行鉴权和准入控制 处理; 并在确定允许所述用户的业务按照要求的 QoS参数在网络中传输的 情况下, 对网络边缘的传送功能模块的流量转发行为发出门控制、 带宽分 配、 DSCP标记控制、 聚合和适配控制命令等等。
步骤 71至步骤 73的 QoS请求和协商处理流程比较适合用于需要有 QoS保证路径的点到点或点到多点数据业务。
4、 用户终端通过业务信令和路径耦合式专用 QoS信令配合进行两阶 段的 QoS请求和协商时,相应的具体的动态 QoS协商处理流程如图 8所示, 可以分为两个处理阶段 , 所述的路径耦合式专用 QoS信令是指 QoS信令路 径与其所服务的用户数据流路径相同; 下面将对所述的两个处理阶段分别 进行说明:
在第一阶段中: 步骤 81 : 用户通过业务控制功能模块向网絡发起业务请求, 如呼叫建 立请求等, 在业务建立过程中与对端用户或应用服务器协商此次业务需要 的 QoS参数, 例如, 可以通过 SDP或者 H.323的能力交换进行 QoS参数的 协商;
如果一次业务包含多个数据流, 则对每个数据流分别协商其 QoS参 数;
步骤 82: 业务控制功能模块收到用户的业务请求后, 提取出其中所协 商的 QoS参数信息, 并利用所述的 QoS参数向 RACS发出资源鉴权请求; 步驟 83: RACS收到所述的资源鉴权请求后, 获取该用户的用户配置 文件、 运营商特定策略规则, 并确定网络中当前的资源可用性, 然后, 根 据用户配置文件、运营商特定策略规则及当前的资源可用性对收到的 QoS 请求进行鉴权; 并在确定允许所述用户的业务按照协商的 QoS参数在网络 中传输的情况下, 则 RACS向业务控制功能模块发回确认以及一个准入令 牌(即 Token ) ;
步骤 84: 业务控制功能模块收到所述的准入令牌后, 还需要将其通告 给相应的用户;
需要注意的是: 对于采用筒化处理的情况下, 该处理流程也可以省去 第一阶段的步驟 82至步骤 84; 且此时,在第二阶段只携带或处理第一阶段 所协商的 QoS需求参数, 而不再需要携带或处理令牌了。
在笫二阶段中:
步骤 85:用户通过 RSVP或 NSIS等路径耦合式专用 QoS信令协议向网 络传送层发起资源预留请求, 请求中携带着业务建立过程中所协商的 QoS 需求参数以及准入令牌;
步骤 86: 网络边缘的传送功能模块(即 TF, Transport Functions )收 到用户的资源预留倩求后, 向 RACS发出准入令牌和资源预留请求;
步骤 87: RACS收到所述的请求后, 基于请求中的准入令牌进行准入 控制处理; 并在确定允许所述用户的业务按照协商的 QoS参数在网络中传 输的情况下,向网络边缘的传送功能模块发出资源预留响应,以及门控制、 带宽分配、 DSCP标记控制、 聚合和适配控制命令等等; 所述的网络边缘传送功能模块收到资源预留响应后转发或终结用户 的资源预留请求。
步驟 81到步骤 87的动态 QoS协商处理流程尤其适合用于移动多媒体 业务和终端。 本发明为了与现有技术兼容还提供了以下两种动态 QoS协商处理流 程。
第一种为: 用户终端通过路径耦合式专用 QoS信令协议直接向网络传 送层发起资源预留请求时, 采用的动态 QoS协商流程, 具体如图 9所示, 包括:
步骤 91 : 用户通过 RSVP或 NSIS等路径耦合式专用 QoS信令协议直接 向网络传送层(即网络边缘的传送功能模块)发起资源预留请求;
步骤 92: 网络边缘的传送功能模块收到用户的资源预留请求后, 携带 着用户的资源预留请求信息向 RACS发出资源预留请求;
步骤 93: RACS收到所述的资源预留请求消息后, 获取用户的用户配 置文件、 运营商特定策略规则, 以及当前的资源可用性, 对所收到的准入 控制请求进行鉴权和准入控制; 如果确定允许, 则向网络边缘的传送功能 模块发出资源预留响应, 以及门控制、 带宽分配、 DSCP标记控制、 聚合 和适配控制命令等等; 传送功能模块收到资源预留响应后转发或终结用户 的资源预留请求。
步骤 91至步骤 93的动态 QoS协商处理流程是为了兼容现有技术所述 的 IETF提出的 IntServ/RSVP及其策略控制模型所采用的 QoS参数传递方 式。
第二种为: 用户不与网络进行动态 QoS协商, 只与运营商签订包含 QoS需求参数的服务等级协议(即 SLA ) 时, 所采用的动态 QoS协商处理 流程。 所述的处理流程具体为: 基于用户与运营商签订服务等级协议中的 QoS需求参数, 网管系统或者网络附件子系统通过 RACS将门控制、 带宽 分配、 DSCP标记控制、 聚合和适配控制参数配置在网络边缘的传送功能 模块上。 这一处理流程可以兼容现有技术所述的 IETF提出的 DiffSer及其 策略控制模型所采用的 QoS请求和协商的处理方式。 以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保护范围并 不局限于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围 内,可轻易想到的变化或替换,都应涵盖在本发明的保护范围之内。 因此, 本发明的保护范围应该以权利要求书的保护范围为准。
