Description

一种紧急业务的处理方法和系统
技术领域
本发明涉及通信领域, 尤其涉及一种紧急业务的处理方法和系统。
背景技术
IP多媒体子系统( IP Multimedia Core Network Subsystem, 简称为 IMS ) 是新一代通讯网络的核心,它釆用了会话发起协议( Session Initiation Protocol, 简称为 SIP )体系。 SIP与接入无关, 并具备媒体业务控制功能与承载分离、 呼叫与会话分离、 应用与服务分离、 业务与网络分离、 以及移动网与因特网 业务融合等多种能力。
由于 IMS和接入无关, 所以 IMS下的紧急业务( Emergency Call , 简称 为 EMC ) 可以建设在第三代伙伴组织计划 (Third Generation Partnership Projects , 简称为 3GPP )无线核心网上。 3GPP无线核心网包括通用无线分 组业务(General Packet Radio Service, 简称为 GPRS ) 网络、 系统长期演进 ( System Architecture Evolution , 简称为 SAE ) 网络、 通用移动通信系统 ( Universal Mobile Telecommunications System, 简称为 UMTS ) 。 其中 SAE 也可以称为 EPS (演进的分组系统, Evolved Packet System ) 。
图 1示出了用户设备 ( User Equipment, 简称为 UE )通过 SAE和 UMTS 接入 IMS 的紧急呼叫所涉及的主要网元; 其中, 实线表示信令, 虚线表示 UE的 IP通道。
如图 1所示, UE通过 SAE或 UMTS接入 IMS的紧急呼叫所涉及的主要 网元包括: SAE网络部分的网元、 UMTS网络部分的网元以及 IMS紧急业务 部分的网元。
其中, SAE网络部分的网元用于提供底层的承载管理和移动性管理。 SAE 网络部分的网元包括:增强的无线基站(eNodeB )、移动性管理实体( Mobility Management Entity,简称为 MME )、归属用户服务器( Home Subscriber Server, 简称为 HSS ) 以及用户面数据路由处理网元 ( SAE GW ) ; SAE GW包括分 组数据网网关 (Packet Data Network Gateway, 简称为 P-GW )和服务网关 ( Serving GW, 简称为 S-GW ) ; 其中, P-GW是 SAE系统内的移动锚点, 是 SAE与分组数据网络(Packet Data Network, 简称为 PDN ) 的边界网关, 负责 PDN的接入、 在 SAE与 PDN间转发数据等功能。 MME负责管理和存 储 UE的上下文(例如, UE标识 /用户标识、 移动性管理状态、 用户安全参数 等) , 为 UE分配临时标识, 当 UE驻扎在跟踪区域或者网络时, 负责对 UE 进行鉴权。 HSS用于保存用户签约数据, 当用户签约发生改变时, 比如签约 过期导致签约数据 _撤回 (Subscription Withdrawal ) 时, HSS可以向 MME发 起用户去附着, 从网络中移除该用户。
UMTS 网络主要由 3GPP 无线接入网络(GSM EDGE Radio Access
Network/UMTS Terrestrial Radio Access Network, GERAN/UTRAN, 统称 RAN ) 、 服务通用分组无线服务支持节点 (Serving GPRS Support Node, SGSN ) 、 网关通用分组无线服务支持节点 (Gateway GPRS Support Node, GGSN )和归属位置寄存器(Home Location Register, 简称为 HLR )构成。 在 UMTS中, 用户终端 UE也被称为移动台 ( Mobile Station, 简称为 MS )。 其 中 HLR用于保存用户签约数据, 当用户签约发生改变时, 比如签约过期导致 签约数据撤回 ( Subscription Withdrawal ) 时, HSS可以向 SGSN发起用户去 附着, 从网络中移除该用户。
IMS 紧急业务部分的网元用于控制和处理紧急呼叫的会话。 其中, IMS 紧急业务部分的网元包括: 呼叫会话控制功能模块 (Call Session Control Function, 简称为 CSCF ) , 其是控制会话过程的核心网元, CSCF 包括代理 呼叫会话控制功能模块(Proxy-CSCF, 简称为 P-CSCF )、 查询呼叫会话控制 功能模块(Interrogating-CSCF, 简称为 I-CSCF ) 、 服务呼叫会话控制功能模 块(Serving-CSCF, 简称为 S-CSCF ) 、 E-CSCF。 其中, E-CSCF是紧急呼叫 的会话控制中心, 决定紧急呼叫应该路由到哪个公众安全应答中心 (Public Safety Answering Point , 简称为 PASP ) 。
在现有技术中釆用的 HSS/HLR发起的删除位置过程中, 当 UE/MS具有 紧急业务时, 原 MME/SGSN不会将其去附着, 当切换到目标 MME/SGSN的 时候, 目标 MME/SGSN将向 HSS/HLR发起位置更新, 由于 HSS/HLR已经 将用户数据删除, 所以这个位置更新失败。 这个失败的位置更新导致网络资 源的浪费。
