Description

获取接入位置信息的方法及用户终端和服务器 技术领域
本发明涉及通信技术领域, 尤其涉及一种获取接入位置信息的方法、 用户终端以及服务器。 背景技术
目前 ITU-T和 ETSI分别作为国际和欧洲的电信标准组织都正在制定 未来下一代网络( NGN, Next Generation Network ) 的网絡架构, 如图 1 所示为 ETSI TISPAN NGN网络架构示意图, 基于这种 NGN网络架构 , NGN网络可以分为三大部分: 业务控制与应用部分、 网絡承载部分、 终 端部分, 下面分别对各部分的功能进行描述:
业务控制与应用系统, 包括 IP 多媒体子系统 ( IMS, IP Multimedia Subsystem )、 PSTN/ISDN仿真子系统、 流媒体子系统等, 完成各种应用 的业务控制功能并提供各种业务。
网络承载系统, 包括以下几个子系统:
( 1 ) 网络附着子系统(NASS ): 完成网络接入层的认证授权、 地址 分配、 用户位置信息管理和终端的配置功能;
( 2 )资源接纳控制子系统(RACS ): 基于业务需求完成承载网络资 源的控制、 分配、 管理功能, 保证业务的服务质量;
( 3 )传送子系统: 在上述子系统的控制下完成各种网络^ :艮文的传送 功能; 包括图中的接入承载网 ( Access Transport network )和核心承载网
( Core Transport network )。
用户终端: 包括各种 NGN终端以及用户家庭网, 包括家庭网关、 综 合接入设备 ( IAD, ) , 机顶盒 ( STB, Set Top Box )、 可视电话 ( Video-Phone )、 电脑 (PC )、 无线保真 ( WiFi )手机等。
其中网絡附着子系统 NASS的结构如图 2所示, NASS子系统包括如 下几个功能实体:
( 1 ) AMF ¾入管理功能。
( 2 ) NACF——网络接入配置功能,对于动态主机配置协议 ( DHCP, Dynamic Host Configuration Protocol )接入方式, NACF通常是 DHCP Server (动态主机配置服务器)。
( 3 ) CLF——连接性会话定位功能, 提供 CLF到业务系统的接口。 ( 4 ) UAAF——用户接入授权功能。
( 5 ) PDBF——用户签约数据库功能。
( 6 ) CDCF——用户端设备配置功能。
在这种 NGN架构中,通过引入 NASS及 RACS子系统,屏蔽了底层 传送子系统的差异, 对上提供统一的标准接口。 基于这种架构, 可以实 现业务与接入的分离, 即 NGN业务提供商不需要关注具体的底层传送子 系统的差异, 只需要提供标准的接口与接入网络运营商对接; 接入网络 运营商也可以不关心如何提供具体的 NGN业务, 只需要通过 NASS和 RACS对外提供标准的接口, NGN业务运营商就可以利用承载网的资源 提供有 QOS保证的 NGN业务。
因此, 一个业务系统可以服务多个不同的宽带接入网 (业务系统可 以是某个业务控制与应用子系统, 或者某个具体的网络应用, 例如可以 是 IMS即 IP多媒体系统、 IPTV即 IP电视系统、 或某个网絡游戏), 也 就是说一个用户可以通过不同的接入运营商接入网络, 在多个接入网之 间游牧或漫游(游牧是指用户由一个网络切换到另外一个网络, 切换期 间中断业务; 漫游切换不中断业务; 漫游通常在移动网应用, 游牧在固 网或半移动网如 WIFI、 DSL应用)。 如图 3所示为终端通过不同的接入 网接入业务系统的结构示意图, 无论用户从哪个接入网接入, 都可以得 到相应的业务服务。 这就要求, 当用户向业务系统注册或请求业务时, 业务系统可以从用户接入网的 NASS获取用户的相关信息, 并通过接入 网的 RACS进行网络带宽 /QOS资源的申请和预留,从而保证有效的服务。
由于用户可以在多个接入网之间漫游, 业务运营商需要知道用户的 位置信息(拜访地信息); 通过获取用户的位置信息, 业务系统可以进行 精确的 QOS控制、 提供不同的资费策略(本地、 长途、 漫游)、 提供位 置信息服务等。 但问题是, 当一个终端接入网络时, 通常终端并不知道 本身的接入位置信息。 由于终端是直接向业务系统注册或请求业务的, 这个过程对于接入网是透明的, 所以当终端向业务系统注册时, 如果不 能携带其接入位置信息, 业务系统也就不知道用户在哪个接入网, 当然 也就不知道从哪个接入网获取用户的相关信息并进行相应的 QOS控制 了。
现有技术提供的解决方案是在终端上预先配置接入网信息, 当终端 接入到业务系统时, 将这个预先配置的接入网信息注册到业务系统, 业 务系统根据该信息到对应的接入网查询用户信息并进行 QOS控制。 但现 有技术无法实现终端的游牧或漫游, 当终端从一个接入网游牧或漫游到 另外一个接入网时, 需要手工更改终端上配置的接入网信息, 工作量大、 不灵活。 发明内容
有鉴于此, 本发明所要解决的技术问题是提供一种获取接入位置信 息的方法及相应的用户终端和服务器, 使用户终端能自动获取自己的接 入位置信息, 克服上述现有技术中终端从一个接入网游牧或漫游到另外 一个接入网时, 不能自动更改接入相关信息的缺点。

由所述的用户终端先通过动态主机配置协议发现消息、 动态主机配 置协议请求消息或通知消息请求服务器提供所述的用户终端接入位置信 息, 服务器在动态主机配置协议应答消息中携带所述的动态主机配置协 议选项返回给用户终端。
所述的动态主机配置协议应答消息为动态主机配置协议提供消息, 或者动态主机配置协议确认消息。
所述的动态主机配置协议选项携带的接入位置信息包括接入运营商 标识、 用户接入网标识、 用户接入网网络附着子系统标识或地址、 用户 接入网连接性会话定位功能标识或地址、 用户接入的宽带远程接入服务 器标识或地址、 用户接入的接入设备标识或地址、 用户接入的物理线路 和逻辑链路标识中的一项或多项。
所述的动态主机配置协议选项至少包括类型字段和内容字段, 所述 的类型字段表示该选项所携带的是接入位置信息, 所述的内容字段携带 用户终端的接入位置信息。
用户终端通过发现消息(DHCP Discover )请求提供用户终端的接入 位置信息, 服务器响应用户终端请求, 并在提供消息 (DHCP Offer ) 中 携带所述的动态主机配置协议选项; 或者,
用户终端通过动态主机配置协议请求消息 (DHCP Request )或通知 消息(DHCP Inform )请求提供用户终端的接入位置信息, 服务器响应用 户终端请求, 并在确认消息(DHCPAck ) 中携带所述的动态主机配置协 议选项。
本发明提供的一种用户终端, 包括:
接入位置信息获取模块: 用于接收实现服务器发送的携带接入位置 信息的动态主机配置协议报文, 并从所述的动态主机配置协议报文的选 项中获取所述的接入位置信息, 并将该信息发送到接入位置信息处理模 块;
接入位置信息处理模块: 将所述的接入位置信息保存, 以在向业务 系统注册或请求业务时使用该信息。
根据本发明提供的一种服务器, 用于提供用户终端的接入位置信息, 包括:
接入位置信息处理模块: 用于保存用户的接入位置信息, 以为用户 终端配置所述的接入位置信息;
接入位置信息发送模块: 将接入位置信息处理模块保存的接入位置 信息承载于发送给用户终端的动态主机配置协议报文的接入位置信息选 项中, 并发送给相应的用户终端。
采用如上所述的本发明的技术方案, 克服了现有技术终端从一个接 入网游牧或漫游到另外一个接入网时, 需要手工更改终端上配置的接入 网信息, 工作量大、 不灵活的缺点, 通过对动态主机配置协议(DHCP ) 的扩展, 增加新的 DHCP选项(Option )携带用户接入位置信息, 不需要 更改网络拓朴, 不需要进行用户终端的配置, 用户终端接入网络时可以 自动通过请求消息获取自己的接入位置信息, 也可以不需要请求, 而是 直接由 DHCP服务器(DHCP Server )在 DHCP应答消息中携带新增的 DHCP Option发送到用户终端。 用户终端可以将该信息向业务系统注册, 从而保证了业务系统可以获取终端的接入位置信息。 本发明使用户终端 接入不同网絡, 或同一网络的不同位置时可获取当前的接入位置信息, 实现了支持用户终端的游牧或漫游。 附图说明

为了说明本发明的特点、 特性以及优点, 下面参照附图并结合实施 例对本发明作进一步详细描述。
动态主机配置协议(DHCP )是一种为用户动态配置相关网络参数的 网络协议, 采用自动给客户机分配相关信息的机制。 客户机接入到系统 时, 服务器会将包括 IP地址、 网关和 DNS 服务器等信息的客户网络配 置信息提供给客户机。 客户机从 DHCP 服务器中检索这些信息。 在大型 综合网络中, 动态主机配置协议 ( DHCP, Dynamic Host Configuration Protocol, )是一种用户接入网络时常用的协议, 主机可以通过 DHCP完 成 IP地址等网络参数的自动配置。 下面以用户终端与服务器进行通信所 采用动态主机配置协议 DHCP为例, 描述根据本发明的获取接入位置信息 的方法以及相关设备。
如图 4 所示为标准的 DHCP 交互流程图, 终端接入网络时, 通过 DHCP获取 IP地址、 子网掩码、 DNS等信息, 该过程是由终端向 DHCP Server( NASS系统的部件)请求完成的。用户终端通过 DHCP发现( DHCP Discover )、 DHCP请求( DHCP Request )或 DHCP通知( DHCP Inform ) 消息向 DHCP服务器(DHCP Server )发送请求, DHCP Server向用户终 端返回 DHCP提供 ( DHCP OFFER ) DHCP确认(DHCPAck ) 消息。 DHCP报文可以携带各种 DHCP选项( Option ), 通过这些 Option可以携 带各种信息, 例如 DNS Server、 SIP Server等。
本发明通过扩展 DHCP协议, 在该协议中增加一种新的携带用户终 端的接入位置信息的设置项 DHCP Option, (或者重用已有的设置项, 所 谓重用是指不重新定义新的 Option 号, 而是重新定义已有的 DHCP Option )并且用户终端和具有动态主机配置服务器功能的网络设备支持该 DHCP Option, 该设置项 Option有一个专用的 Code即类型字段, 通过该 Option, 用户终端可以从网络获取接入位置信息 /访问地信息。 DHCP Option格式如下:
CODE Length Content
CODE字段表示类型, 即该 Option为携带用户终端接入位置信息的 Option; Length表示 Option的长度;用户终端的接入位置信息在本 Option 的 Content (内容)字段中携带。 该 DHCP Option可以携带的用户接入位 置信息可以包括以下全部或部分子选项:
1、 接入运营商标识, 例如 "China Telecom"。
2、用户接入网标识,可包括运营商信息、物理区域信息等,例如 "China Telecom Beijing DSL R01"„
3、 用户接入网网络附着子系统(NASS )标识或地址, 例如 "China Telecom NASS 001" 或 "212.100.010.001"。
4、用户接入网连接性会话定位功能(CLF )标识或地址,例如 "China Telecom CLF 001" 或 "212.100.011.001"。 5、 用户接入的宽带远程接入服务器 (BRAS )标识或地址, 例如: "Beijing BRAS001,,或" 212.100.100.00 。

基于上述标准的 DHCP交互过程, 只需要通过 DHCP Server向用户 终端发送的 DHCP OFFER和 /或 DHCP Ack消息中携带上述 Option,就可 以把终端的接入位置信息 /拜访地信息发送给用户终端。
如图 5 所示为本发明用户终端获取位置信置及上报业务系统的流程 图, 对于 DHCP Option进行如下处理:
1 ) DHCP Server端发出的 DHCP Offer和 DHCP Ack消息携带上述 本发明新增的 DHCP Option, 该 DHCP Option携带用户接入位置信息, 该信息可以包括上述可以携带的用户接入位置信息各子选项。
2 )用户终端收到携带本发明提出的 DHCP Option的 DHCP Offer或
DHCP Ack, 从该 Option中获取接入位置信息, 因接入位置信息中可能包 括多个子选项, 终端可根据需要获取全部或部分子选项。
3 )用户终端可以将该信息向业务系统注册, 从而保证业务系统可以 获取用户终端的接入位置信息。
用户终端可以通过 DHCP Discover请求本发明中定义的 Option选项 ,
DHCP Server通过 DHCP Offer应答终端的请求,该 DHCP Offer中通过本 发明定义的 DHCP Option携带用户接入位置信息。终端也可以通过 DHCP Request或 DHCP Inform请求提供本发明中定义的 Option选项, DHCP Server通过 DHCP Ack应答终端的请求,该 DHCP Ack中通过本发明定义 的 DHCP Option携带用户接入位置信息。
DHCP交互过程中, 完成 DHCP Relay (中继)功能的网络设备 (如 宽带远程接入服务器 BRAS或数字用户线接入复用器 DSLAM ), 对于携 带该 DHCP Option的 DHCP报文的处理应与不携带该 DHCP Option的 DHCP 艮文相同, 处理过程中 , 网络设备对于该 DHCP Option不做任何 改动。
本发明通过对 DHCP的扩展, 增加新的设置项 DHCP Option携带用 户接入位置信息, 不需要更改网络拓朴, 不需要进行用户终端的配置, 用户终端接入网络时可以自动通过请求消息获取自己的接入位置信息, 也可以不需要请求,而是直接由 DHCP Server在 DHCP Offer或 DHCP Ack 消息中携带新增的 DHCP Option发送到用户终端。 终端可以将该信息向 业务系统注册, 从而保证了业务系统可以获取终端的接入位置信息。 本 发明使终端接入不同网络, 或同一网络的不同位置时可获取当前的接入 位置信息, 实现了支持终端的游牧或漫游。
为实现本发明所提出的方法, 本发明还提供一种用户终端和一种实 现 DHCP服务器功能的设备。
如图 6所示为实现本发明提供的方法的用户终端模块结构示意图, 包括:
DHCP接入位置信息获取模块: 用于接收 DHCP服务器或实现 DHCP 服务器功能的其它设备发来的携带接入位置信息的 DHCP报文, 并从所述 的 DHCP报文的选项中获取所述的接入位置信息, 并将该信息发送到位置 信息处理模块;
接入位置信息处理模块: 将所述的接入信息保存于本地, 从而可以 在向业务系统注册或请求业务时使用该信息。
如图 7为实现本发明提供的方法的实现 DHCP服务器功能的设备模块 结构示意图, 包括:
接入位置信息处理模块: 用于保存用户的接入位置信息, 以向用户 终端配置所述的接入位置信息;
DHCP接入位置信息发送模块:将接入位置信息处理模块保存的用户 接入位置信息承载于发送给用户终端的 DHCP报文的接入位置信息选项 中, 并发送给相应的用户终端。
如果网络设备支持内置的 DHCP Server功能, 则也可以由这些网络 设备实现与独立的 DHCP Server相同的功能。
本发明提供的在下一代网络中用户终端获取接入位置信息的方法、 用户终端, 以及具有网络设备。
以上所述仅为本发明示范性实施例而已, 并不用于限制本发明的权 利范围。 本领域技术人员在不脱离本发明的实质和精神的前提下, 可以 有多种变更方案实现本发明, 凡运用本发明所作的等效结构变化, 均落 入本发明的权利要求的保护范围之内。
