Description

一种多模单待终端在网络注册的方法和装置 技术领域
本发明涉及通信领域, 尤其涉及一种多模单待终端在网络注册的方法和 装置。 背景技术
在移动通信网络中, 2G/3G网络已经过多年的部署。 随着系统架构演进 (System Architecture Evolution, SAE)/长期演进项目 (Long Term Evolution, LTE)网络技术的发展 (有时也被称为 4G), SAE/LTE 网络已经覆盖到一些城 区和话务热点地区, 导致在目前的通信网络中, SAE/LTE网络和 2G/3G 网 络并存。
针对不同的网络承载机制, 可将移动通信的语音业务分为如下几类: 第一类是由电路交换 (Circuit Switching, CS)域承载语音业务, 在核心网 由移动交换中心( Mobile switch Center, MSC )/拜访位置寄存器 (Visit Location Register, VLR)和归属位置寄存器 HLR(Home Location Register, HLR)提供 路由控制和业务处理, HLR中记录了当前用户设备( User Equipment, UE ) 在 CS域中的哪个 MSC下附着;
第二类是由分组 (Packet Switching, PS)域承载语音业务, 在核心网由 IP 多媒体子系统 (IP Multimedia System, IMS)提供路由控制和业务处理, IMS 中的归属用户服务器( Home Subscriber Server, HSS )记录了 UE在 IMS域 中的注册状态。
多模单待的终端(Single Radio), 指可以支持 LTE和 2G/3G两种网络制 式, 但一次只能附着在一个网络, 即要么附着在 SAE/LTE 网络, 要么附着 在 2G/3G网络; 多模双待的终端 (Dual Radio), 指可以支持 LTE和 2G/3G两 种网络制式, 而且可以同时附着在两个网络, 即同时附着在 SAE/LTE 网络 和 2G/3G网络。
对于多模单待的 SR终端, 因为 SR终端在 LTE/IMS网络与 2G/3G网络 之间移动时, 该终端可能位于 2G/3G CS域, 也可能位于 LTE/IMS域。 这样 在该终端作为语音呼叫的被叫时, 就存在在哪个域接续终端的问题。 现有技 术中, 往往建设一个融合的数据中心归属位置寄存器 HLR/归属用户服务器 HSS, 它具有原来 CS域的 HLR和 IMS域的 HSS的功能。
一种方法是融合 HLR/HSS到用户附着的 MSC上去查询 UE在 CS域的 真实状态, VMSC收到 PSI消息以后在 CS域发起对于 UE的预寻呼, 如果 UE当前确实驻留在 CS网络, 则 UE回寻呼响应, VMSC返回 PSI ACK消 息给融合 HLR/HSS; 如果 UE当前不是驻留在 CS网络,则 UE寻呼无响应, 寻呼失败后 VMSC也返回 PSI ACK消息给融合 HLR/HSS (响应消息中指示 UE当前在 CS状态为不可及); 融合 HLR/HSS收到 PSI ACK消息后, 将 UE 在 CS/PS的状态和位置信息返回给 SCC AS; SCC AS根据融合 HLR/HSS返 回的 UE在 CS/IMS的状态和位置信息, 以及 UE签约的业务, 当前呼叫的 类型等做域选择, 选择在哪一个域接续呼叫。
对于多模单待的 UE,由于融合的 HLR/HSS不能根据已有的信息确定当 前 UE到底接入在哪个域,每次都要到 CS域的 MSC去查询 UE状态和信息, 触发对于 UE的预寻呼, 而预寻呼会占用较多的寻呼资源, 假设 UE实际上 并不驻留在 CS网络, 则寻呼实际上也是失败的, 而 MSC要等待寻呼完成, 这样导致呼叫的时延也会增加。
发明内容
为此, 本发明实施例提供一种多模单待 UE在网络注册的方法和装置, 以保证从网络侧看只有一个域是注册的, 避免被叫进行域选择时, 还要通过 寻呼等额外的消息来确定当前 UE注册在哪个域。
一方面, 本发明实施例提供了一种多模单待用户设备 UE进行网络注册 的方法, 包括:
融合 HLR/HSS接收多模单待 UE在第一网络的注册请求;
确定所述多模单待 UE在第二网络已注册;
向第二网络发送注销消息, 取消所述多模单待 UE在所述第二网络的注 册。
另一方面, 本发明实施例提供了一种数据融合装置, 该装置包括: 接收模块, 用于接收多模单待 UE在第一网络的注册请求;
确定模块, 用于确定所述多模单待 UE在第二网络已注册;
发送模块, 用于向第二网络发送注销消息, 取消所述多模单待 UE在所 述第二网络的注册。
基于上述技术方案, 本发明实施例提供的多模单待 UE 网络注册方法和 融合数据装置, 通过主动取消 UE在第二网络的注册, 当单待的 UE在第一 网络与第二网络之间移动时, 从网络侧来看只有一个域是注册的, 从而避免 了被叫进行域选择时, 还要通过寻呼等额外的消息来确定当前 UE注册在哪 个域, 避免了寻呼资源的浪费, 减少了时延。 附图说明
为了更清楚地说明本发明实施例的技术方案, 下面将对本发明实施例中 所需要使用的附图作简单地介绍, 显而易见地, 下面所描述的附图仅仅是本 发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的 前提下, 还可以根据这些附图获得其他的附图。
图 1是本发明实施例一方法流程图;
图 2是本发明实施例二方法流程图;
图 3是本发明实施例三方法流程图;
图 4是本发明装置实施例结构框图。 具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明的一部分实施例, 而不 是全部实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创 造性劳动的前提下所获得的所有其他实施例, 都应属于本发明保护的范围。
图 1示出了本发明实施例一的流程图, 包括:
5101 , 融合 HLR/HSS接收多模单待 UE在第一网络的注册请求; 本发明实施例中的所有 UE为多模单待 UE。 UE向第一网络发送注册请 求可以为附着请求。
5102, 确定所述多模单待 UE在第二网络已注册;
这里, 如果多模单待 UE 在第一网络或第二网络已注册, 则融合 HLR/HSS会记录 UE在第一网络或第二网络的状态, 融合 HLR/HSS根据自 身记录的 UE的状态, 确定 UE是否在第二网络已注册。
5103, 向第二网络发送注销消息, 取消所述多模单待 UE在所述第二网 络的注册。
这里, 注销消息可以为 Cancel Location消息, 也可以为 RTR消息, 取 消 UE在第二网络的注册后, UE只注册在第一网络。
本发明实施例提供的方法, 通过主动取消 UE在第二网络的注册, 当单 待的 UE在第一网络与第二网络之间移动时, 从网络侧来看只有一个域是注 册的, 从而避免了被叫进行域选择时, 还要通过寻呼等额外的消息来确定当 前 UE注册在哪个域, 避免了寻呼资源的浪费, 减少了时延。 在本发明实施例中, 根据第一网络和第二网络的不同, 下面将分别进行 描述。
本发明实施例二提供一种多模单待 UE在 IMS网络注册后, 发现该 UE 已在 2G/3G网络注册的处理方法, 如图 2所示, 包括:
S201、 UE在 EPC网络附着;
该步骤为现有的标准流程, 在此仅作简单介绍。 UE可以向 MME发送 附着请求, MME与融合 HLR/HSS之间通过位置更新请求和位置更新响应交 互, 完成鉴权、 IP地址分配、承载建立等流程,完成 UE在 LTE网络的附着。 这里, MME向融合 HLR/HSS发送的注册请求可以为位置更新请求。
5202、 UE在 IMS域注册;
该步骤也是现有的标准流程, 融合 HLR/HSS与代理呼叫会话控制功能 P-CSCF, 查询呼叫会话控制功能 I-CSCF, 服务呼叫会话控制功能 S-CSCF 之间交互, 完成鉴权等流程, 并在 HLR/HSS里记录 UE当前在 IMS网络是 注册的, 并保存服务 UE的 S-CSCF地址。
5203、 确定 UE在 CS网络已注册;
UE在 CS域附着时, 融合 HLR/HSS均要记录 UE在 CS域的状态, 所 以融合 HLR/HSS可以根据自身记录的 UE在 CS域的状态, 判断 UE是否在 CS网络已注册。
5204、融合 HLR/HSS向 UE在 CS网络附着的 VMSC发送 Cancel Location 消息, 取消 UE在 CS网络的注册。
融合 HLR/HSS 根据 S201 中位置更新请求消息中的 UE SRVCC Capability信元,判断 UE如果是单待终端,而且 UE在 CS网络中已有附着, 则向 VMSC发送 Cancel Location消息, 取消 UE在 CS网络的注册。 CS网络的 VMSC收到 Cancel Location消息以后, 删除该 UE的用户数 据, 向融合 HLR/HSS回送 Cancel Location Ack消息; 融合的 HLR/HSS收到 Cancel Location消息以后, 记录该 UE在 CS网络的状态为未附着, 附着的 MSC地址为空。
需要指出的是, 本发明实施例中的附着可以为注册的一部分, UE在 CS 域附着,也可以说成 UE在 CS域注册。 因为 SAE/LTE由 IMS提供路由控制 和业务处理, UE在 IMS注册即为在 SAE/LTE网络注册。 同样, UE在 CS 域附着即为在 2G/3G附着。
本发明实施例提供的方法, 通过主动取消 UE在 CS域的注册, 当单待 的 UE在 2G/3G与 SAE/LTE之间移动时, 从网络侧来看只有一个域是注册 的, 从而避免了被叫进行域选择时, 还要通过寻呼等额外的消息来确定当前 UE注册在哪个域, 避免了寻呼资源的浪费, 减少了时延。 本发明实施例三提供一种多模单待 UE在 2G/3G 网络注册时, 发现该 UE已注册 SAE/LTE的 IMS域时的处理方法, 如图 3所示, 包括:
S301、 UE在 CS网络附着;
该步骤为现有的标准流程, 在此仅作简单介绍。 UE与 VMSC以及融合 HLR/HSS 之间相互交互, 完成鉴权流程, 以及位置更新和插入用户的位置 更新数据。
S302、 确定 UE在 IMS网络已注册;
UE在 IMS网络时, 融合 HLR/HSS均要记录 UE在 IMS网络的状态, 所以融合 HLR/HSS可以根据自身记录的 UE在 IMS网络的状态, 判断 UE 是否在 IMS网络已注册。
S303、 融合 HLR/HSS 向服务 UE 的 S-CSCF 发送注册终止请求 ( Registration Termination Request, RTR )消息,取消 UE在 IMS网洛的注册。
融合 HLR/HSS根据 UE在向 IMS注册时发送注册请求即位置更新请求 消息中的 UE SRVCC Capability信元, 判断 UE如果是单待终端, 而且 UE 在 IMS网络中已注册, 则向服务 UE的 S-CSCF发送 RTR消息,取消 UE在 IMS网络的注册。 之后, S-CSCF更新自己的内部数据库, 删除该用户。
同样需要指出的是, 本发明实施例中的附着可以为注册的一部分, UE 在 CS域附着, 也可以说成 UE在 CS域注册。 因为 SAE/LTE由 IMS提供路 由控制和业务处理, UE在 IMS注册即为在 SAE/LTE网络注册。 同样, UE 在 CS域附着即为在 2G/3G附着。
本发明实施例提供的方法, 通过主动取消 UE在 IMS域的注册, 当单待 的 UE在 2G/3G与 SAE/LTE之间移动时, 从网络侧来看只有一个域是注册 的, 从而避免了被叫进行域选择时, 还要通过寻呼等额外的消息来确定当前 UE注册在哪个域, 避免了寻呼资源的浪费, 减少了时延。 本发明实施例提供一种融合数据装置, 如融合 HLR/HSS, 如图 4, 具体 包括:
接收模块 401, 用于接收多模单待 UE在第一网络的注册请求; 确定模块 402, 用于确定所述多模单待 UE在第二网络已注册; 发送模块 403, 用于向第二网络发送注销消息, 取消所述多模单待 UE 在所述第二网络的注册。
进一步地, 该融合数据装置可以包括判断模块 404, 用于根据所述接收 模块 401接收到的注册请求消息中的 UE SRVCC Capabi l i ty信元, 判断 UE 为多模单待 UE。
当第一网络为系统演进架构 SAE/长期演进 LTE 网络, 所述第二网络为 2G/ 3G网络时,发送模块 403用于向所述多模单待 UE附着的拜访移动交换中 心 VMSC发送 Cance l Loca t ion消息。 该装置还可以包括记录模块 405, 用于 记录所述多模单待 UE在 2G/ 3G网络的状态为未注册。
当第一网络为 2G/ 3G网络, 所述第二网络为 SAE/LTE网络时, 发送模块 403用于向服务所述多模单待 UE的服务呼叫会话控制功能 S-CSCF发送注册 终止请求 RTR消息。
本发明实施例提供的融合数据装置, 通过主动取消 UE在第二网络的注 册, 当单待的 UE在第一网络与第二网络之间移动时, 从网络侧来看只有一 个域是注册的, 从而避免了被叫进行域选择时, 还要通过寻呼等额外的消息 来确定当前 UE注册在哪个域, 避免了寻呼资源的浪费, 减少了时延。
