Description

一种 NGN网络系统中终端用户漫游控制方法 技术领域
本发明属于通讯领域, 特别涉及下一代网络 (NGN)体系架构下对移动终端 漫游的控制方法。 背景技术
目前终端用户的漫游, 一般是指移动终端用户在不同的地域之间的漫游, 移动终端用户的漫游为无缝移动, 在移动终端用户移动的时候, 可以随时改变 其网络接入点而不中断正在进行的服务会话 。
对于下一代网络系统体系架构中的核心控制设备软交换来 i兌 它是基于分 组交换数据网的, 而在数据网上是不分距离, 地域的, 这样终端用户在全球任 何地方向软交换设备注册。 对于软交换来说, 对终端用户的处理都是一样的。 目前软交换并没有提供根据终端用户的接入区域的不同,使用的网络资源的不 同, 而作不同的处理。 发明公开
本发明的目的是提供一种 NGN网络中终端用户漫游的控制方法, 解决 NGN 网络体系架构中漫游区域的划分, 终端用户在不同区域接入的漫游问题, 以及 对终端用户的漫游控制的问题。
为了实现上述目的,本发明提供一种 NGN网络系统中终端用户漫游控制方 法, NGN网络系统包括基于分组交换数据网的核心控制设备和移动终端; 其特 点在于, 该方法包括如下步骤:
步骤一, 据 IP地址段划分区域;
步骤二,设置一终端用户漫游到各个区域内的各个 IP地址段的漫游属性, 所述漫游属性包括漫游类型和业务属性;
步骤三,根据核心控制设备中设置的漫游类型, 设置核心控制设备中一终 端用户的漫游权限, 使每一种漫游类型对应一种漫游权限; 同时这些漫游权限 可以任意的组合, 形成不同类型的漫游权限; 步骤四, 当该终端从一区域向核心控制设备注册时, 将该终端的 IP地址 上传至该核心控制设备, 如果该 IP地址不存在于核心控制设备, 则注册失败; 如果该 IP地址存在于该核心控制设备,该核心控制设备根据该终端的 IP地址 得出对应该终端的漫游类型;
步骤五, 进一步判断该终端用户是否有该漫游类型的漫游权限, 如果有, 则该终端用户注册成功, 否则注册失败; 当该终端用户注册成功时, 该终端用 户能够在该相应区域使用网络服务。
在本发明上述的 NGN网络中终端用户漫游控制方法中, 是以 IP地址段来 划分区域, 此区域具有广泛的概念, 不局限于某个地域, 可以是某个地域中一 部分 IP地址段组成, 也可以是一个或者多个地域的 IP地址段或者部分 IP地 址段组成。 某个区域内可以有一个或者多个 IP地址段, 但某个 IP地址段只属 于某个区域内。 这个可以由运营商根据实际的情况进行规划, 并且不同的软交 换系统上, 规划可以不相同。
进一步地本发明所述的终端用户漫游控制方法中对于某个地域软交换系 统中, 可以灵活的定义漫游类型, 比如: 本地网内漫游, 本地网外漫游, 省内 漫游, 国内漫游, 国际漫游等, 这些可以根据实际的情况进行定制, 在这些规 则定义好以后, 软交换系统根据这些规则来判断终端用户的漫游类型, 漫游类 型是和用户相对应的, 同一个 IP地址段对一个用户可以是一种漫游类型, 而 对于另外的用户来说可以是其他的漫游类型, 也可以是本地。
进一步地, 本发明所述的终端用户漫游控制方法中, 还包括对软交换系统 的终端用户的漫游权限的管理, 按照终端用户漫游类型的不同, 终端用户的漫 游权限也相应的具有不同类型的, 也就是说在软交换系统中, 具有多少种漫游 类型, 就具有多少种漫游权限, 在设置软交换系统中漫游权限的时候是按照用 户进行设置的, 而不是按照终端进行设置的, 每个用户都可以设置不同的漫游 权限。 用户在具有漫游权限区域内, 带此用户的终端可以接入软交换系统, 使 用网络服务, 相反在不允许的漫游区域内, 即使终端可以接入软交换系统, 用 户也无法使用网络服务。
进一步地, 在本发明所述的终端用户漫游控制方法中, 访终端主要包括 H. 248协议终端, H. 323协议终端, SIP协议终端和 MGCP协议终端。 各个协议 终端在数据网上向网络核心控制设备注册, 终端的注册信息将包括终端的 IP 地址上传到软交换系统, 软交换在完成该终端用户的认证后, 根据终端用户设 置的漫游属性, 得到终端用户的漫游类型。
进一步地, 在本发明所述的终端用户漫游控制方法中, 还包括了终端用户 在漫游区域的业务属性和计费的管理, 在终端用户离开其归属区域的时候, 如 果在这个区域配置了漫游业务属 则终端用户在这个区域使用网络服务的时 候, 则使用此区域的漫游业务属性, 比如在漫游地呼叫漫游地的用户, 贝 I掮于 本地漫游呼叫, 而呼叫归属地的用户, 则属于长途漫游呼叫。 对于漫游终端用 户的计费管理, 则根据用户的是否发生了漫游, 漫游的类型, 使用的网络服务 类型, 网络核心控制设备把这些终端用户漫游信息写入到 CDR文件中, 计费中 心根据这些信息, 和相应的计费策略进行计费。 ·
进一步地, 在本发明所述的终端用户漫游控制方法中, 如果该终端带有多 个用户, 漫游权限是控制到终端上的每个用户, 注册的时候只要终端上有一个 用户具有相应的漫游权限, 那么此终端就可以进行漫游注册, 在注册成功后只 有具有漫游权限的用户可以进行呼叫和其他业务, 而对于没有漫游权限的其他 用户, 即使终端注册成功了, 这类用户也不能够进行呼叫和其他的业务。
进一步地, 在本发明所述的终端用户漫游控制方法中, 如果终端在向软交 换系统注册的时候, 是通过边缘网关如 B G W等, 则此时对于软交换系统来 说, 看到的只是边缘网关的 IP地址的注册, 软交换系统无法分辨出具体的某 个终端 IP地址, 因此需要边缘网关做一些处理, 将终端的实际注册 IP地址上 报到软交换系统这样软交换系统就可以区分出通过边缘网关注册到软交换系 统的每个终端, 从而可以对这些终端上的用户进行漫游管理与控制。
本发明采用上述方法, 对终端用户的漫游进行管理和控制, 进而限制终端 用户在某些区域内可以接入核心控制设备, 使用网络服务, 而在另外的一些区 域就不可以接入核心控制设备, 从而就不能够使用网络服务。 同时, 在终端用 户在不同的区域接入核心控制设备时, 将根据区域的不同, 具有不同的权限、 业务属性以及不同的计费策略。 .
由于本发明釆用了按照 IP地址段划分区域, 定义各区域内的漫游类型的 办法,使得网络核心控制设备能够对每一个终端用户在不同区域的接入进行控 制与管理 附图简要说明
图 1是本发明的实现流程图;
图 2 是终端直接接入提供漫游功能的下一代网络核心控制设备的系统结 构示意图;
图 3 是终端通过边缘网关接入提供漫游功能的下一代网络核心控制设备 的系统结构示意图。 实现本发明的最佳方式
下面结合附图对本发明作进一步的详细描述:
图 1给出了本发明的方法的流程图。 如图 1所示, 其中:
在步骤 Sl, 以 IP地址段来划分区域, 此区域具有广泛的概念, 不局限于 某个地域, 可以是某个地域中一部分工 P地址段组成, 也可以是一个或者多个 地域的 IP地址段或者部分 IP地址段组成。 某个区域内可以有一个或者多个
IP地址段, 但某个 IP地址段只属于某个区域内。 这可以由运营商根据实际的 情况进行规划, 并且在不同的核心控制设备上, 规划可以不同。
在步骤 S2, 在软交换系统中定义终端用户漫游到各个区域内的各个 IP地 址段的漫游属性以及各 IP地址段内的终端用户的业务属性等。 其中, 所述的 漫游属性包括漫游类型。 这里, 漫游类型可以灵活地定义, 比如: 本地网内漫 游, 本地网外漫游, 省内漫游, 国内漫游, 国际漫游等, 这些可以根据实际的 情况进行定制, 在这些规则定义好以后, 软交换系统根据这些规则来判断终端 用户的漫游类型, 漫游类型是和用户相对应的, 同一个 IP地址段对一个用户 可以是一种漫游类型, 而对于另外的用户来说可以是其他的漫游类型, 也可以 是本地。
. 在步骤 S3, 根据核心控制设备中的漫游类型的定义, 定义核心控制设备 中终端用户的漫游权限, 其中每一种漫游类型对应一种漫游权限, 同时这些漫 游权限可以任意的组合, 形成不同类型的漫游权限。
这样, 能够实现对软交换系统的终端用户的漫游权限的管理。按照终端用 户漫游类型的不同, 终端用户的漫游权限也相应地具有不同的类型, 也就是说 在软交换系统中, 具有多少种漫游类型, 就具有多少种漫游权限, 在设置软交 换系统中漫游权限的时候是按照用户进行设置的, 而不是按照终端进行设置 的, 每个用户都可以设置不同的漫游权限。 用户在具有漫游权限区域内, 带此 用户的终端可以接入软交换系统, 使用网络服务, 相反在不允许的漫游区域 内, 即使终端可以接入软交换系统, 用户也无法使用网络服务。 因此, 在核心 控制设备中对漫游权限的控制, 是控制到每个用户上的。
在步骤 S4, 终端向核心控制设备注册的时候, 终端将其 IP地址上传至核 心控制设备。
在步骤 S5, 核心控制设备查询其中是否包含该 IP地址。
在步骤 S6, 如果核心控制设备包含终端上传的 IP地址, 则得到该终端的 漫游类型, 如果不包含, 则终端注册失败。
在步骤 S7, 在得到终端的漫游类型后, 进一步判断该终端的用户是否具 有此漫游类型的漫游权限。 ·
在步骤 S8, 如果该终端的用户有此漫游类型的漫游权限, 则该终端注册 成功, 否则注册失败。
在步骤 S9, 终端注册成功后, 终端用户可以使用网络服务。
在步骤 S10, 如果该终端带有多个用户, 漫游权限是控制到终端上的每个 用户, 注册的时候只要终端上有一个用户具有相应的漫游权限, 那么此终端就 可以进行漫游注册,在注册成功后,判断各用户是否有使用此网络服务的权限。 只有具有漫游权限的用户可以进行呼叫和其他业务, 而对于没有漫游权限的其 他用户, 即使终端注册成功了, 这类用户也不能够进行呼叫和其他的业务。
在步骤 Sll, 当用户在漫游地使用网络服务的时候, 用户可以使用漫游地 的一些业务属性。
在步骤 S12, 核心控制设备将用户的漫游信息记录到 CDR文件中。
在步骤 S13, 终端用户使用网络完毕。
在本发明方法中, 终端主要包括 H. 248协议终端, PL 323协议终端, SIP 协议终端和 MGCP协议终端。 各个协议终端在数据网上向网络核心控制设备注 册, 终端的注册信息将包括终端的 IP地址上传到软交换系统, 软交换在完成 该终端用户的认证后, 根据终端用户设置的漫游属性, 得到终端用户的漫游类 型。
在本发明的方法中,还包括了终端用户在漫游区域的业务属性和计费的管 理, 在终端用户离开其归属区域的时候, 如果在这个区域配置了漫游业务属 性, 则终端用户在这个区域使用网络服务的时候, 则使用此区域的漫游业务属 性, 比如在漫游地呼叫漫游地的用户, 则属于本地漫游呼叫, 而呼叫归属地的 用户, 则属于长途漫游呼叫。 对于漫游终端用户的计费管理, 则根据用户的是 否发生了漫游, 漫游的类型, 使用的网络服务类型, 网络核心控制设备把这些 终端用户漫游信息写入到 CDR文件中, 计费中心根据这些信息, 和相应的计费 策略进行计费。
在本发明的方法中,如果终端在向软交换系统注册的时候, 是通过边缘网 关如 B G W等, 则此时对于软交换系统来说, 看到的只是边缘网关的 IP地址 的注册, 软交换系统无法分辨出具体的某个终端 IP地址, 因此需要边缘网关 做一些处理, 将终端的实际注册 IP地址上报到软交换系统, 这样软交换系统 就可以区分出通过边缘网关注册到软交换系统的每个终端, 从而可以对这些终 端上的用户进行漫游管理与控制。
图 2是本发明所述的终端 T1在 IP网络上直接接入具有漫游功能的下一代 网络的核心控制设备的系统结构示意图。 终端 T1 下带两个用户分别为 Subl 和 Sub2, 终端 T1为在区域 A中登记注册到核心控制设备 SS1的用户, 区域 A 为终端 T1的归属地, 其 IP地址段为 202. 202. *. *; 区域 B和区域 C是终端 T1 有漫游权限的区域, 其 IP地址段分别为 192. 192. *. *和 100. 100. *. *, 其中用 户 Subl具有区域 B中的漫游权限, 而用户 Sub2则具有区域 C中的漫游权限; 在区域 D终端 T1没有漫游权限, 其 IP地址段为 197. 197. *. *。
此时 IP地址区域表的配置如表 1所示:
表 1
网号 区号 IP地址 子网掩码 注释
1 1 202. 202. 0. 0 255. 255. 0. 0 区域 A

1 3 100. 100. 0. 0 255. 255. 0. 0 区域 C
1 4 197. 197. 0. 0 255. 255. 0. 0 区域 D 此时漫游属性表的配置如表 2所示:
表 2
Figure imgf000009_0001
其中,用户 Subl和 Sub2都配置使用漫游属性表中的模板号 1,对 Subl用 户的漫游权限配置为: 本地网内漫游 +省内漫游, 而对 Sub2用户的漫游权限 配置为: 本地网内漫游 +国内漫游。
下面分别描述终端 T1在归属地区域 A中向核心控制设备 SS1的注册和用 户 Subl和 Sub2的呼叫流程、 终端 T1从归属地区域 A漫游到区域 B和 C中向 核心控制设备 SS1的注册流程以及用户 Subl和 Sub2的呼叫流程、 终端 T1从 归属地区域 A漫游到区域 D中向核心控制设备 SS1的注册流程以及用户 Subl 和 Sub2的呼叫流程。
( 1 )终端11在归属地区域 A中向核心控制设备 SS1的注册流程以及终端 T1的用户 Subl和 Sub2的呼叫流程。
当终端 T1在区域 A中通过 IP网络向核心控制设备 SS1注册, 终端 T1将 自己的 I P地址 202. 202. *. *上报到核心控制设备 SS1, 核心控制设备 SS1查 询表 1, 得到此 I P地址落在区域 A的 I P地址段内, 根据为终端 T1的两个 用户 Subl和 Sub2指定的漫游属性模板号和 IP地址查询表 2判断出用户 Subl 和 Sub2发生的是本地网内漫游,此时的终端 T1的注册流程和正常终端的注册 流程相同, 在终端 T1注册成功后, 其上面带的两个用户 Subl和 Sub2的漫游 状态为本地网内漫游, 此时这两个用户的呼叫流程和正常用户的呼叫流程相 同。
(2) 终端 T1从归属地区域 A漫游到区域 B和 C中向核心控制设备 SS1 的注册流程, 以及终端 T1的用户 Subl和 Sub2的呼叫流程。
当终端 T1从区域 A漫游到区域 B和 C通过 IP网络向核心控制设备 SS1 注册的时候, 由于区域 B和 C不是终端 T1的归属地, 此时终端 T1属于漫游注 册, 此时的注册流程为, 终端 T1 将自己的 IP 地址, 在 B区域时为 192. 192. *. *, 在 C区域时为 100. 100. *. *, 还有其他的相关信息, 都上报到 核心控制设备 SS1, 核心控制设备 SSI在接收到这些信息后, 首先根据 IP地 址查询表 1得到这两个 I P地址段不是终端 T1的本地的 I P地址, 并根据为 终端 T1的用户 Subl和 Sub2配置的漫游模板号和 IP地址查询表 2进一步得到 终端 T1的漫游类型, 而后查询终端 T1的漫游权限, 由于终端 T1具有 B和 C 区域的漫游权限, 所以注册时候的权限判断就通过了, 终端 T1注册成功, 核 心控制设备 SS1修改终端 T1的状态为相应的漫游状态和其注册的 IP地址。当 终端 T1在区域 B注册成功后, 用户 Subl具有区域 B内的漫游权限, 可以进行 呼叫等网络服务, 并且用户 Subl使用区域 B的业务属性使用网络服务。 而用 户 Sub2没有区域 B内的漫游权限 则用户 Sub2在区域 B内不能够使用网络服 务。 当终端 T1在区域 C注册成功后, 用户 Sub2具有区域 C内的漫游权限, 可 以进行呼叫等网络服务,并且用户 Sub2使用区域 C的业务属性使用网络服务。 而用户 Subl由于没有区域 C内的漫游权限, 所以在区域 C内不能够使用网络 服务。
( 3)终端 T1从归属地区域 A漫游到区域 D中向核心控制设备 SS1的注册 流程,以及终端 T1的用户 Subl和 Sub2的呼叫流程。
当终端 T1从区域 A漫游到区域 D, 通过 IP网络向核心控制设备 SS1注册 的时候, 由于区域 D不是终端的归属地, 此时终端 T1属于漫游注册, 此时的 注册流程为, 终端 T1将终端的 IP地址 197. 197. *. *, 还有其他的相关信息, 都上报到核心控制设备 SS1。 核心控制设备 SSI在接收到这些信息后, 首先根 据 IP地址查询表 1得到这个 I P地址段不是本地的 I P地址, 然后根据 IP 地址和用户的漫游属性模板号查询表 2得到此终端用户的漫游类型而后查询 终端 T1上用户 Subl和 Sub2的漫游权限 由于终端 T1上没有一个用户有漫游 到区域 D的权限, 因此核心控制设备 SS1向终端 T1返回无漫游权限, 拒绝终 端在区域 D的注册。 由于终端 T1没有注册成功, 所以终端 T1上的两个用户
Subl和 Sub2无法进行呼叫和其他的业务。
对于图 3中终端 T1在 C区域中的时候, 是通过边缘网关 BG1向核心控制 设备 SS1注册的, 此时对于网络核心控制设备 SS1接收到的终端 IP地址为边 缘网关 BG1 的 IP 地址 219. 150. 172. 66, 以及终端 Tl 的实际 IP 地址 100. 100'. *. *, 网络核心装置根据终端 T1的实际 IP地址判断出终端的注册区 域, 进而得到终端的漫游类型。 由于在区域 C中终端 T1有漫游权限, 所以终 端 T1注册成功。 当终端 T1在区域 C注册成功后, 用户 Sub2具有区域 C内的 漫游权限, 可以进行呼叫等网络服务, 并且用户 Sub2使用区域 C的业务属性 使用网络服务。 而用户 Subl没有区域 C内的漫游权限, 则用户 Subl在区域 C 内不能够使用网络服务。
当然, 本发明还可有其他多种实施例, 在不背离本发明精神及其实质的情 况下, 熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形, 但 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 工业应用性
