Description

说明书 一种资源接纳控制融合的方法、 设备及系统
[1] 技术领域
[2] 本发明涉及通信技术领域, 尤其设计一种资源接纳控制融合的方法、 设备及系 统。
[3] 发明背景
[4] 目前, 对资源接纳控制的研究— L…为国内外标准化组织的热点课题, ITU-T ( 国际电信联盟电信标准化部门) 、 TISPAN (Telecommunications and Internet Converged Services and Protocols for Advanced
Networking, 电信和互联网融合业务及高级网络协议) 、 3GPP (3rd Generation Partnership Project , 第三代伙伴计划) 都对其进行丁不同程度的研究。
[5] 各组织对资源接纳控制的称谓不同, 功能架构和研究的范围等也有一定程度的 差别。 具体如下所述:
[6] 资源接纳控制首先在 TISPAN中明确提出, 其相关功能称为 RACS (Resource and Admission Control
Subsystem, 资源接纳控制子系统) 。 如图 1所示为 RACS架构示意图, RACS将 业务层 (IP Multimedia Subsystem
, IMS) 的资源需求与网络承载层的资源分配相关联, 主要完成策略控制、 资源 预留、 接纳控制、 NAT (Network Address
Translation, 网络地址转换) 和防火墙穿越等功能。
[7] RACS架构中 SPDF (Service Policy Decision
Function, 基于业务的策略决策功能) 南向接口的功能有: 控制 NAT穿越与门控 、 传送协议类型策略、 带宽控制、 QoS
Marking (服务质量标记:) 、 使用测量与统计报告、 资源状态同步等功能。 本文 中所述南向接口指策略决策单元 /设备与承载传送单元 /设备之间的逻辑接口。
[8] ITU-T中相关功能称为 RACF (Resource and Admission Control
Functions , 资源接纳控制功能) 。 RACF架构如图 2所示, 其中策略决策设备 PD- FE南向接口的功能有: 资源预留与指定、 QoS处理 (如包标记、 策略应用) 、 门 控、 NAT与地址映射、 资源使用信息报告、 动态防火墙工资模式选择等功能。
[9] 3GPP中与资源接纳控制相关功能被称为 PCC (Policy Control and
Charging, 策略和计费控制) 。 其架构如图 3所示, 其中 PCRF (Policy Control and Charging Rules
Function, 策略与计费控制功能) 南向接口的功能有: IP-CAN (IP Connectivity Access
Network, IP连接接入网) 会话连 发起和维护、 PCC决策的请求和提供、 协 商 IP-CAN的承载建立模式、 终止 IP-CAN连接等功能。
[10] 从最初的设计出发点, TISPAN的 RACS架构主要面向固定网络、 3GPP的 PCC 架构主要面向移动网络、 ITU-T的 RACF架构则同吋面向固定和移动网络。
[11] ITU-Ts TISPAN以及 3GPP等标准组织目前的资源控制和接纳控制的网络架构 由于最初的基本假设的差异, 造成各自标准技术的发展并不完全同步和一致, 但随着 ALL-IP (全 IP) 、 FMC (Fixed-Mobile
Convergence, 固定移动融合) 技术的出现与发展, 从网络运营商到设备制造商 幵始研究在一些共性较大的部件和接口上做一些融合的工作, 逐步统一相关网 元和接口, 最终简化网络, 降低建网成本。
[12] 如图 4及图 5为上述几个架构的大部分接口图, 针对图中所示接口, 目前业界提 出将南向接口 Gx、 Re与 la等接口融合, 图 5中双箭头线所指的接口为需要融合的 接口。 另外, 7 载传送设备 RCEF (Policy and Charging Enforcement
Function, 资源控制执行功能) 、 C-BGF (核心边缘网关功能) 、 GW (网关) 、 GGSN (Gateway GPRS Supporting
Node, 网关通用分组无线业务支持节点) 、 IMS Access
GW (接入网关) 、 BRAS (宽带接入服务器)等为满足上述接口融合, 也需要达到 设备的融合。
[13] 在实现本发明过程中, 发明人发现若实现上述融合, 至少存在如下困难:
[14] 1、 现有的几个标准系统难以相互妥协来实现统一的南向接口;
[15] 2、 即使能够妥协, 在技术上要实现统一南向接口以及相关流程存在相当的难 度;
[16] 3、 现网设备若要支持融合后完全统一的接口, 需要进行大规模改造, 这样改 造成本的很高, 从成本和运营的角度来看并不可行。
