Description
异常状态下用户的接入方法、 装置和一种通信系统 本申请要求于 2010年 12月 30日提交中国专利局、 申请号为 201010616152.6、 发明名称为 "异常状态下用户的接入方法、 装置和一种通 信系统" 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 本发明涉及移动通信领域, 尤其涉及异常状态下用户的接入方法、 装 置和一种通信系统。 背景技术 现有的全球移动通信系统 ( GSM , Global System for Mobile Communications ) 网络架构由基站(BTS , Base Transceiver Station ) 、 基站 控制器 (BSC , Base Station Controller ) 、 移动交换中心 (MSC , Mobile Switching Center )和归属位置寄存器(HLR, Home Location Register )等网 元构成。 从网元的地理分布看, BTS放置在覆盖地点, BSC、 MSC和 HLR 一般集中放置在城市中心, BTS通过传输链路与 BSC连接。 各网元之间互 相配合才能完成用户之间的通信, 其中, HLR的功能之一是负责存储国际 移动用户识别码 ( IMSI, International Mobile Subscriber Identity )和国际移 动用户电话号码( MSISDN, Mobile Subscriber ISDN Number )等用户信息。 当用户试图附着到 GSM网络上时, 用户上报 IMSI, GSM网络据此在 HLR 中查找相应的用户记录。 如果 HLR中没有用户记录, 则该用户不能附着到 网络中。
在现有的 GSM网络中, 各网元之间的信息传输大多使用地面链路。 如 此, 在异常状态下, 例如, 发生灾害时, 传输容易中断并且短期内难以恢 复。 即使使用移动通讯车进入灾害地点进行通讯恢复, 也会面临难以获取
外界传输的问题。 因为, 即使终端能够和 BTS或移动通讯车进行无线通信, 但由于用户信息无法得到 HLR的校验, 网络仍然认为该用户是一个异常用 户, 不会让其附着到网络。 在传输恢复正常时, 对于某些外地用户, 例如, 从外地奔赴灾区实施 紧急救援的用户, 如果没有开通漫游服务或者在 HLR中没有查找到记录, 也会被 HLR拒绝, 不能附着到网络。 然而, 在灾害场景下, 对于这些外地 用户, 提供通信服务显然是必要的。
相类似的, 在其他制式的网络, 例如, 宽带码分多址 (WCDMA ,
Wideband Code Division Multiple Access ) 系统、 码分多址( CDMA, Code
Division Multiple Access )和长期演进 ( LTE, Long Term Evolution )等, 也 会存在相同的问题。
换言之, 现有的通信网络架构尚不能对异常用户提供在本地进行用户 信息检索校验的功能, 因此无法让这些用户附着到网络。
发明内容 本发明实施例提供异常状态下用户的接入方法、 装置和一种通信系统, 以便让异常状态下的用户附着到网络, 为其提供通信服务。 本发明实施例提供一种异常状态下用户的接入方法, 包括: 本地应急 中心判断发起附着流程的用户是否能够继续所述附着流程; 若所述附着流 程不能继续, 则所述本地应急中心为所述用户分配临时通信标识并允许所 述用户附着到网络。 本发明实施例提供一种异常状态下用户的接入装置, 所述装置是一本 地应急中心, 所述本地应急中心包括: 判断模块, 用于判断发起附着流程 的用户是否能够继续所述附着流程; 临时标识分配模块, 用于若所述判断 模块的判断结果为所述附着流程不能继续, 则为所述用户分配临时通信标
识并允许所述用户附着到网络。
本发明实施例提供一种通信系统, 所述通信系统包括基站和与所述基 站相连的本地应急中心; 所述基站, 用于与发起附着流程的用户交互, 将 所述用户的用户信息传输给所述本地应急中心; 所述本地应急中心包括判 断模块和临时标识分配模块; 所述判断模块, 用于根据所述基站传输的用 户信息, 判断所述发起附着流程的用户是否能够继续所述附着流程; 所述 临时标识分配模块, 用于若所述判断模块的判断结果为所述附着流程不能 继续, 则为所述用户分配临时通信标识并允许所述用户附着到网络。
从上述本发明实施例可知, 在异常状态下, 本发明实施例提供的技术 方案可以使该用户与其他用户通信, 进而为该用户提供应急通信服务。 附图说明 为了更清楚地说明本发明实施例的技术方案, 下面将对现有技术或实 施例描述中所需要使用的附图作筒单地介绍, 显而易见地, 下面描述中的 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 出创造性劳动性的前提下, 还可以如这些附图获得其他的附图。

基站, 可以是 GSM或 CDMA中的基站( BTS, Base Transceiver Station ), 也可以是 WCDMA中的基站( NodeB ), 还可以是 LTE中的演进型基站( eNB 或 e-NodeB, evolutional Node B ), 本发明并不限定, 但为描述方便, 下述 实施例以 GSM为例进行说明。
请参阅附图 1 , 是本发明实施例提供的异常状态下用户的接入方法流程 示意图, 可以如下所述。
S101 , 本地应急中心判断发起附着流程的用户是否能够继续该附着流 程。
在本发明实施例中,本地应急中心是一个与基站( BTS, Base Transceiver Station )相连的设备, 可以直接相连也可以间接相连, 可以通过无线接口相 连也可以通过有线连接, 例如光纤、 同轴电缆等。 本地应急中心可以获取 用户信息并存储于本地。 例如, 本地应急中心获取用户信息的一种方式是, 当本地应急中心无法通过网络访问 HLR时, 可以通过本地文件获取用户信 息, 例如, 通过 USB接口从 U盘获取关于用户信息的记录文件, 本地应急中 心的软件系统导入此文件, 获取用户信息。 另一种方式是, 当本地应急中 心能够通过网络访问 HLR时, 通过远程访问 HLR获取用户信息记录, 例如, HLR启动文件传输协议( FTP, File Transfer Protocol )服务器, 本地应急中 心作为 FTP客户端访问 FTP服务器以获取用户信息。
在 BTS和 BSC的连接正常时,本发明实施例还提供了一种获取用户信息 的方式, 即, 在上行传输方向, BTS将消息转发到本地应急中心, 本地应急 中心对消息进行分析, 获取用户信息, 然后将消息返还至 BTS, BTS再将消 息发给 BSC, 或者在下行传输方向, BSC将消息发送至 BTS, BTS将该消息
转发到本地应急中心, 本地应急中心对消息进行分析, 获取用户信息, 然 后将消息返还至 BTS , BTS继续处理此消息。
在本发明实施例中, 用户信息可以包括国际移动用户识别码(IMSI, International Mobile Subscriber Identity ) 和 /或国际移动用户电话号码 ( MSISDN, Mobile Subscriber ISDN Number )等。
S102, 若发起附着流程的用户的附着流程不能继续, 则本地应急中心 为用户分配临时通信标识并允许该用户附着到网络。
与现有 GSM网络不同, 在本发明实施例中, 若本地应急中心判断发起 附着流程的用户的附着流程不能继续, 例如, 在本地查找不到该用户的用 户信息、 或无法通过 HLR查找该用户的用户信息或者在 HLR中也查找不到 该用户的用户信息, 则不是直接拒绝该用户, 而是为该用户建立用户记录, 同时为其分配临时通信标识,例如,临时 MSISDN,允许该用户附着到网络。 于是, 该用户可以在本地应急中心的管控下与本地应急中心中具有用户记 录的用户通信。
从上述本发明实施例可知, 由于本地应急中心与基站相连, 在判断发 起附着流程的用户是不能继续该附着流程时, 可以为该用户分配临时通信 标识并允许用户附着到网络。 因此, 在异常状态下, 本发明实施例提供的 本地应急中心与基站实际上构成了一个类似于普通 GSM网络的小型 GSM网 络, 本地应急中心具有了类似于 MSC或 HLR的功能, 可以在本地对该用户 进行管理, 使该用户与其他用户通信, 进而为该用户提供应急通信服务。
本文中所述异常状态, 可以是指不能正常通信的状态, 例如, 最常见 的一种情形是, BTS和 BSC之间的连接中断, 此时, BTS无法将用户信息通 过 BSC传输至 MSC或 HLR以接受校验。 在这种状况下, 根据本发明提供的 一个实施例, 由于 BTS和本地应急中心仍然处于相连状态, 因此, BTS仍然 可以将发起附着流程的用户的用户信息转发至给本地应急中心, 本地应急
中心据此查找存储于本地的用户信息, 若本地记录有该用户的用户信息, 则可以判断发起附着流程的用户能够继续附着流程, 于是允许用户附着到 网络。
在异常状态下,另一种常见的情形是, BTS和 BSC之间的连接正常, BTS 可以将本地用户的用户信息通过 BSC传输至 MSC或 HLR以接受校验, 但是, MSC或 HLR不能校验没有开通漫游用户的用户信息。 在这种状况下, 根据 本发明提供的另一个实施例, 当没有开通漫游用户发起附着流程、 核心网 的 MSC或 HLR响应用户而向该用户反馈消息时, 本地应急中心截获核心网 反馈给该用户的消息, 若该消息是拒绝所述用户附着到网络的拒绝消息, 则本地应急中心判断发起附着流程的用户不能继续附着流程。
本地应急中心判断发起附着流程的用户是否能够继续所述附着流程, 在所述附着流程不能继续时为所述用户分配临时通信标识并允许所述用户 附着到网络的信令流程如附图 2所示。
5201 , BTS与发起附着流程的用户交互, 向本地应急中心转发 "建立指 示(EST IND, ESTablished INDcation )" 信令。
若 EST IND包含 IMSI等用户信息, 则本地应急中心在正式用户数据库 和临时用户数据库中查询该 IMSI是否存在; 若正式用户数据库和临时用户 数据库中不能查询到该 IMSI, 则本地应急中心通过 BTS向移动台 (MS , Mobile Station )返回 "连接管理服务拒绝 (CM Service Rej , Connection Management Service Rejection )" 信令, 释放独立专用信道( SDCH, Solely Dedicated CHannel ), 终止此次呼叫, 并开始临时通信标识分配流程。
5202, 如果 EST IND中没有包含 IMSI等用户信息, 则本地应急中心通 过 BTS向 MS下发 "身份请求( Identity Request )" 信令, 请求 MS上报 IMSI 等用户信息。
5203, MS上报 "身份响应 ( Identity Response )" 信令后, 本地应急中
心查询其中的 IMSI是否为正式用户和临时用户, 处理流程如步骤 S201。 S204, 在终止上述业务流程后, 本地应急中心为该用户分配临时通信 标识。
在本地应急中心为用户分配临时通信标识后, 由于该临时通信标识是 临时分配的, 用户使用可能并不习惯。 在本发明实施例中, 本地应急中心 提供了一种为用户修改临时通信标识的机制, 即, 本地应急中心接收用户 爹改临时通信标识的请求, 本地应急中心根据该请求, 将爹改后的临时通 信标识通知用户, 用户可以按照修改后的临时通信标识使用。 具体地, 用 户拨打 "特殊前缀加自己期望的临时通信标识" 构成的号码, 将自己期望 的临时通信标识向本地应急中心上报。 例如, 用户拨打 "*#00#" +自己期 望的临时通信标识, 本地应急中心侧解析出此特殊前缀, 不进行话路的搭 建, 直接将其通话请求中止, 然后将之前为用户分配的临时通信标识更新 为用户期望的临时通信标识并通知用户, 例如, 向该用户发送 "您的电话 号码已更新, 您的新号码为 ......(即用户期望的临时通信标识) " 的短信。 具体流程如附图 3所示。
