Description

一种通信系统、 装置和方法
本申请要求在 2012年 4月 28日提交中国专利局、 申请号为 201210135000.3、 发明名 称为"一种通信系统、 装置和方法"的中国专利申请的优先权, 其全部内容通过引用结合在 本申请中。 技术领域
本发明涉及通信技术领域, 尤其涉及一种通信系统、 装置和方法。 背景技术
在本地网络部署场景中, UE (用户终端)可以通过家庭基站接入到与该家庭基站关联 的本地网络, 这种技术称为 LIPA ( Local IP Access, 本地 IP接入)。 本地网络包括家庭网 络、 企业网络等。 UE 也可以通过家庭基站系统直接接入 Internet, 这种技术称为 SIPTO ( Selected IP Traffic Offload, 选择的 IP业务分流)。
在 3GPP (第三代移动通信标准化组织) R10阶段, 实现了 UE通过家庭基站接入本地 网络的 LIPA技术, UE接入到家庭基站后, 数据直接通过 LGW ( Local Gateway, 本地网 关)访问本地网络,而不需要经过核心网。从控制面和用户面而言, LGW实现了 PGW( PDN Gateway, 分组数据网网关) 的部分功能, 但是由于 LGW是位于本地网络中, 不是位于 3GPP运营商中的网络实体, 因此相对 PGW而言, LGW实现的功能相对筒单。
另夕卜, 3GPP也在讨论希望能够釆用 LIPA架构实现 UE通过家庭基站建立 SIPTO连接 的方法。
目前, 协议支持 PGW与 PCRF ( Policy and Charging Rules Function, 策略与计费规则 功能)之间的接口,对于连接到 PGW的 PDN (分组数据网)连接, PCRF可以动态向 PGW 发送 QOS ( Quality of Service, 服务盾量)控制策略。
附图 1所示为 R10阶段的 LIPA架构, 如果 UE建立正常到核心网的承载连接, 数据 面通道是 UE通过 Uu接口到 (演进的) 家庭基站( H(e) B ), 再通过 S1-U接口到 SGW ( Serving GW, 服务网关), 经 S5接口到 PGW, 通过 PGW的 SGi接口连接到访问的网络 中。 其中, H(e) B通过 S 1 -MME接口连接至 MME ( Mobility Management Entity , 移动性 管理实体), ΜΜΕ通过 S11接口连接至 SGW。 但是, 如果 UE建立 LIPA连接, 数据面通 道是从 UE到 H(e) B, 再通过 LGW的 SGi接口接入本地网络, 而不需要经过核心网的功 能实体。
其中, LGW在本地网络中可以实现部分 PGW的功能, 例如 IP地址分配等。 R10阶 段为了实现筒单, LGW与 H(e)NB在同一个物理实体上实现(即合设)。 但是, LGW不支 持 PCRF与 LGW之间的接口, 不能与 PCRF通信。 因此本地网络不支持 PCC ( Policy Control and Charging, 动态策略控制与计费)分配 过程, 当 UE发起 LIPA专用承载的建立过程, 或者发起对 LIPA承载的 QoS修改等过程都 会被网络拒绝。
3GPP后续讨论了 LIPA后续演进架构以及通过家庭基站接入的 SIPTO架构,如附图 2 所示, 相较于 R10阶段的 LIPA架构, 主要区别在于 LGW和 H(e)NB在不同物理实体上实 现(即分设 ), LGW与 H(e) B之间通过 Sxx接口连接, 以更好支持 UE移动时的业务连 续性。 其中, LGW通过 S5接口连接至 SGW, H(e) B通过 S 1-U接口连接至 SGW, 并通 过 S 1 -MME接口连接至 MME , MME和 SGW之间通过 S 11接口连接。在 LGW通过 SeGW ( Security GW, 安全网关)连接至 SGW, H(e) B经 SeGW和(演进的) 家庭基站网关 ( H(e) B GW )连接至 SGW和 MME。 但是, 演进的 LIPA/SIPTO架构中不支持 PCRF与 LGW之间的接口, 仍然没有实现对 LIPA/SIPTO承载的动态 QOS 控制过程, 也不支持 LIPA/SIPTO专用承载的建立和对 LIPA/SIPTO承载的 QOS修改。
这就意味着所有通过 LIPA/SIPTO 访问的业务都必须釆用相同的默认 QoS ( default QoS )值, 该默认的 QoS作为签约信息保存在 HSS ( Home Subscriber Server, 归属用户服 务器)中,UE在附着时由 MME从 HSS中获取,该签约的默认 QoS值为非保证比特率( non GBR )承载, 不能保证实时业务的需求。 同时, 随着用户需求的增加, 例如用户可能需要 通过 LIPA方式访问家庭的打印机, 也可能通过手机访问家里的笔记本的电影资源库实现 手机的在线视频等。 如果都釆用签约的默认 QoS值为这些业务提供服务显然不能满足业 务的 QoS需求。
由此可见, 随着网络应用的发展, 用户釆用 LIPA/SIPTO连接通过家庭基站发起不同 的业务时, 需要网络也能够为这些业务提供不同的 QoS控制。 首先, 这就需要实现本地网 络中 LGW与 PCRF之间的通信, 然后, 进一步基于 LGW和 PCRF的通信实现动态 PCC 分配。 发明内容

为了能够在本地网络中实现 LGW和 PCRF的通信,以通过 LGW和 PCRF的通信实现 动态 PCC分配,为 UE请求的 LIPA或 SIPTO承载动态分配 PCC策略,使得釆用 LIPA/SIPTO 连接的不同业务釆用不同的 QoS承载传递数据 , 本地网络也需要与部署动态 PCC架构的 实体(即 PCRF )之间建立接口连接。
PCRF作为策略决策实体负责产生 QoS 策略等 PCC策略。
宏网络中, PGW执行 PCEF ( Policy and Charging Enforcement Function, 策略与计费 执行功能) 的功能, 主要执行业务数据流发现(如服务数据流发现, 业务数据流发现)、
QoS映射、 计费等功能。 PCRF将产生的 PCC策略发送到 PGW。
与 PGW不同, LGW是由家庭(或企业)与运营商共同部署完成, 一般位于家庭(或 企业) 内部。 如果 H(e) B与 LGW合设, 则部署了 H(e) B的家庭会同时有一个 LGW。 随着 LIPA架构的演进, 允许 H(e)NB和 LGW分设后, 同一个居民楼或同一企业可使用一 个 LGW。
目前 LIPA架构中不支持 LGW和 PCRF之间的接口, PGW与 PCRF之间无法通信 , 并且, 相对于 PGW在网络中的数目, LGW的数量庞大, 即便能够将 PGW与 PCRF直接 相连, 将大量的 LGW直接连接至 PCRF对于 PCRF的冲击会非常大, 管理也很复杂。
据此, 本发明提供了一种通信系统, 用于实现 LGW和 PCRF之间的通信。
并且,基于该通信系统进一步提供了一种用于本地网络的 PCC管理系统, 用以管理本 地网络的分流承载, 支持釆用 LIPA/SIPTO传输的承载连接的动态 PCC 策略分配, 实现 LIPA/SIPTO系统中的承载 QoS控制。
下面结合附图对本发明优选的实施方式进行详细说明。
如附图 3所示, 本发明实施例提供了一种通信系统, 该系统包括 LGW和 PCRF , 还包 括 PAMGW (策略聚合管理网关)。 该 PAMGW用于通过与 LGW相连接的第一接口接收 LGW的消息, 通过与至少一个
PCRF相连接的第二接口发送至 PCRF , 以及通过第二接口接收 PCRF的消息, 并通过第一 接口发送至 LGW。
该系统中, PAMGW作为接口,分别连接 LGW和至少一个 PCRF ,用于 PCRF和 LGW 之间的信令交互。
该系统中, HeNB可以与 LGW合设于同一物理实体,也可以与 LGW分设于不同的物 理实体(图 3中所示仅为 H(e) B与 LGW的逻辑接口并非实际接口)。
在一个具体实现中, PAMGW具有至少一个第一接口, 每个第一接口连接一个 LGW。 该 PAMGW具体用于:根据预设的第一接口的接口标识与第二接口的接口标识的对应 关系, 确定接收 LGW的消息的第一接口对应的第二接口, 将 LGW的消息通过确定的第 二接口发送至 PCRF , 以及根据对应关系确定接收 PCRF的消息的第二接口对应的第一接 口, 将 PCRF的消息通过确定的第一接口发送至 LGW。
该实现方式中, 多个 LGW通过一个 PAMGW与 PCRF相连接 , 可降低与 PCRF相连 接的 PAMGW的数量。
其中, LGW可直接连接至 PAMGW的第一接口。
为了实现筒单, 一个 LGW同一时刻仅与一个 PAMGW相连接。 即一个 LGW只能通 过一个 PAMGW与 PCRF进行信令交互。
较佳地, 一个 LGW可与至少两个 PAMGW相连接, 从而分担 PAMGW的负荷。 优选地, 在一个 LGW连接多个 PAMGW时, 由 LGW执行 PAMGW的选择功能。 其中, LGW执行选择功能可以根据静态配置信息选择确定 PAMGW, 也可以根据网 络侧返回的查询结果选择确定 PAMGW。
在一个具体实现中, LGW根据预先配置的用户终端的指示信息与 PAMGW标识的对 应关系, 确定用户终端的指示信息对应的 PAMGW标识, 并向确定的 PAMGW标识对应 的 PAMGW发送消息, 以及接收确定的 PAMGW标识对应的 PAMGW的消息。
实际应用中, 该指示信息可以为 APN ( Access Point Name , 接入点名称)、 PGW标识 等。
例如, LGW根据预先配置的 APN与 PAMGW标识的对应关系, 确定用户终端请求的 APN对应的 PAMGW标识;或者, LGW根据预先配置的用户终端的 PGW标识与 PAMGW 标识的对应关系, 确定用户终端请求的 PGW对应的 PAMGW的标识。
在另一个具体实现中, LGW接收通过 DNS ( Domain Name Server, 域名服务器) 查 询获取的 PAMGW地址, 并向根据 PAMGW地址确定的 PAMGW发送消息, 以及接收根 据 PAMGW地址确定的 PAMGW的消息。
具体地, LGW通过查询网络中设置的 DNS服务器获取 PAMGW地址, 在 DNS服务 器中配置有指示信息与 PAMGW标识的对应关系, LGW发送查询请求至 DNS服务器, 该 查询请求中携带指示信息, 该指示信息可以是用户终端请求的 APN、 PGW标识等, DNS 服务器根据配置的对应关系查找请求中携带的指示信息对应的 PAMGW 地址, 并将该 PAMGW的地址携带在查询结果中返回给 LGW。
此处仅为举例, 具体实现时, LGW执行 PAMGW的选择功能可以有多种方式, 只要 能够达到确定 LGW当前使用的 PAMGW的目的即可用于本发明。
其中, PAMGW还用于通过第二接口将第一接口接收的同一用户终端的不同连接请求 的消息发送至 LGW指定的 PCRF。
具体地, 由 LGW指定 PCRF , LGW可以为针对同一用户终端的不同连接请求指定相 同的 PCRF ,也可以为针对同一用户终端的不同类型的连接请求指定不同的 PCRF。 PAMGW 根据 LGW发送的消息中携带的指定的 PCRF的标识,将 LGW的消息发送至指定的 PCRF。

具体实施例三, 在现有的 R10架构中, 本地网络也不支持对已建立的 LIPA或 SIPTO 承载的修改过程,如果 UE发起承载修改请求, LGW将会拒绝这一请求。该具体实施例中, 在本地网络中釆用上述 PCC架构后, UE支持动态 PCC ,可以实现不同 QoS的承载修改过 程, 如附图 8所示, 具体过程如下:

第二种情况: 以下结合具体实施例四〜五对 SGW与 LGW之间使用 PMIP相连接的情 况进行详细说明。
具体实施例四, 如附图 9所示, 建立 LIPA或 SIPTO PDN连接的具体过程如下: 步骤 901: UE发起附着 PDN连接建立消息至 MME ,请求 MME为其建立 LIPA或 SPT0 APN连接。
