一种通信方法和本地管理***
本申请要求于 2009 年 12 月 30 日提交中国专利局、 申请号为 200910238861. 2、 发明名称为 "一种通信方法和本地管理***" 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 本发明涉及通信领域， 尤其涉及一种通信方法和本地管理***。 背景技术
GSM ( Global System for Mobi le Communications , 全球禾多动通讯系 统） 俗称"全球通"， 由欧洲开发的数字移动电话网络标准， 是一种第二代 移动通信技术， 它的开发目的是让全球各地共同使用一个移动电话网络标 准， 让用户使用一部手机就能行遍全球。 GSM***包括 GSM 900： 900MHz、 GSM1800: 1800MHz 及 GSM_1900、 1900MHz等几个频段。
GSM是一种广泛应用于欧洲及世界其它地方的数字移动电话***， GSM 使用的是时分多址技术， GSM将资料数字化， 并将数据进行压缩， 然后与其 它的两个用户数据流一起从信道发送出去， 另外的两个用户数据流都有各 自的时隙。
如图 1所示， 为现有技术中一种 GSM的网络结构示意图， 包括： 用户 设备 (UE, User Equipment )、基站子*** (BSS, Base Station Sub-system) 和网络子*** （NSS， Network SubSustem网）。 基站子*** （BSS) 包括基 站 (BTS, Base Transceiver Station) 禾口基站控制器 (BSC, Base Station Control ler);网络子***（NSS )包括移动交换中心（MSC， Mobi le Switching Center ) 禾口操作维护中心 ( 0MC， Operation Operation & Maintenance Center) , 归属位置寄存器 (HLR, Home Location Register), 访问位置寄 存器 (VLR, Vi sitor Location Register ),鉴权中心（AUC， Authentication Center) 禾口设备标志寄存器 (EIR, Equipment Identification Register) 其中， 移动交换中心与访问位置寄存器一般集成在一起， 通常称为 MSC/VLR o
网络子*** NSS 还可以连接操作支持子*** （0SS， Operation and Maintenance Support System) , 其中该操作支持子*** (OSS) 主要包括： 网路管理中心 （丽 C)， 数据后处理*** （DPPS ), 用户识别卡个人化管理中 心 (PCS, Personal Communications Service ), 安全性管理中心 ( SEMC, Security Management Center)。
MSC/VLR还可以连接公用数据网 (PDN， Packet Data Network) , 公用 电话网 （PSTN, Publ ic Switched Telephone Network ) , 综合业务数字网 ( ISDN, Integrated Service Digital Network) 。
基站子*** BSS是 GSM***中与无线蜂窝方面关系最直接的基本组成 部分， 它通过无线接口直接与用户设备相连， 负责无线发送接收和无线资 源的管理。
网路子*** NSS是整个***的核心， 它对 GSM移动用户之间及移动用 户与其它通信网用户之间通信起着交换、 连接与管理的功能。 主要负责完 成呼叫处理、 通信管理、 移动管理、 部分无线资源管理、 安全性管理、 用 户数据和设备管理、 计费记录处理、 公共信道、 信令处理和本地运行维护 基站子*** BSS主要负责无线信息的发送与接收及无线资源管理； 同 时， 它与 NSS相连， 实现移动用户间或移动用户与固定网路用户之间的通 信连接， 传送***信息和用户信息等； 当然， 也要与操作支持子*** 0SS 之间实现互通。
基站控制器（BSC ) , BSC是基站子***（BSS )的控制部分， 支持与 MSC 间 A接口， 与 BTS间的 Abi s接口及与 0MC间的 X. 25接口。 两个用户设备 进行通信时， 该两个用户设备即可以分别通过不同的基站 BTS通信， 如图 2 所示， 也可以通过同一个基站 BTS通信， 如图 3所示。
如图 2所示， 为现有技术中另一种 GSM***结构示意图， 用户设备 21、 22连接不同的基站 BTS， 当两个用户设备 21、 22进行通话或短信时， 需要 搭建一条从用户 21到核心网的 MSC， 再从核心网到用户 22的通讯链路， 这 样语音或短信会从用户 21发送到核心网， 再从核心网发送到用户 22。
如图 3所示， 为现有技术中另一种 GSM***结构示意图， 用户设备 31、
32连接相同的 BTS， 基站 BTS发送到核心网的语音或短信内容由核心网原 样还给 BTS。
由上述描述可知， 当进行通信时， BSC控制 BTS的资源分配， 由核心网 进行用户和话单相关的处理。 也就是说， 进行通信的两个用户设备， 不论 是同属于一个基站还是不同基站， 在进行通信时， 控制信令的处理要经过 BTS到 BSC再到核心网这条路径。
当 BTS和 BSC间的连接出现故障或中断时， 由于缺乏语音信令的处理， 通信将无法实现， 即使该两个用户设备处在同一个基站下， 也无法进行语 音通话或短信。尤其当小区处于偏远地区时， BSC和 BTS之间传输距离很远， 存在很大的不确定性， 如果由于某种原因造成传输中断后， 所有业务都将 无法继续。 由于基站地处偏僻， 传输很长， 定位问题很难， 可能导致业务 长时间的中断， 严重影响通信质量。 发明内容

图 6为本发明另一实施例的一种本地管理*** 60的结构示意图； 图 7为本发明另一实施例的一种通信方法流程示意图； 图 8为本发明另一实施例的一种通信方法流程示意图。 具体实 式 以下描述中， 为了说明而不是为了限定， 提出了诸如特定***结构、 接口、 技术之类的具体细节， 以便透切理解本发明。 然而， 本领域的技术 人员应当清楚， 在没有这些具体细节的其它实施例中也可以实现本发明。 在其它情况中， 省略对众所周知的装置、 电路以及方法的详细说明， 以免 不必要的细节妨碍本发明的描述。
本发明的技术方案， 可以应用于各种通信***， 例如： GSM， 码分多址 (CDMA, Code Division Multiple Access ) ***， 宽带码分多址 （WCDMA, Wideband Code Division Multiple Access Wireless ) , 通用分组无线业 务 (GPRS , General Packet Radio Service) , 长期演进 (LTE, Long Term Evolution) 等。 但为描述的方便， 下述实施例以 GSM为例进行详细说明。 移动终端（Mobi le Terminal ) ,也可称之为移动用户 (UE， User Equipment ) , 移动用户设备等， 可以经无线接入网 （例如， RAN, Radio Access Network) 与一个或多个核心网进行通信， 移动终端可以是移动台， 如移动电话 （或 称为 "蜂窝" 电话） 和具有移动终端的计算机， 例如， 可以是便携式、 袖 珍式、 手持式、 计算机内置的或者车载的移动装置， 它们与无线接入网交 换语言和 /或数据。
如图 4所示， 为本发明实施例的一种通信*** 400的结构示意图， 主 要如下所述。
该通信*** 400可以包括传输平面 410， 控制平面 420， MSC/VLR45和 HLR46 o 该传输平面 410可以包括多个通过光纤相互耦合的基站 43。 同样， 该控制平面 420可以包括多个通过光纤相互耦合的基站控制器 44， 而且， 这些光纤用于连接上述的基站 43。上述基站 43，基站控制器 44和 MSC/VLR45 相互之间可以通过光， 电或无线方法进行通信。 多个信号可以通过光路在 上述的传输平面 410传输， 以及经过上述基站 43。
用户设备 40A、 40B可以通过基站 43接入网络， 例如， 通过同一个基 站接入， 或通过不同的基站接入。
MSC/VLR45还可以与 HLR46 , 公用数据网， 公用电话网和综合业务数字 网通信连接。
另外， 至少一些基站， 例如位于传输平面 410边缘的基站， 可以用于 将数据传输到其它基站或其它基站控制器， 其中， 上述数据被应用于上述 传输平面 410。 同样地， 至少一些基站控制器， 例如位于控制平面边缘的基 站控制器， 可以用于数据传输到其它基站控制器或其它 MSC/VLR, 其中， 上 述数据被应用于上述控制平面 420。
如图所示的通信*** 400只是显示四个基站 43，两个基站控制器 44和 一个 MSC/VLR45 , 通信*** 400可以包括任意数量的基站 43， 基站控制器 44或 MSC/VLR45。 而且， 如图 4所示， 当多个基站控制器 44和多个基站 43 之间是一对一的关系时， 可以是多个基站 43与一个基站控制器 44连接， 反之亦然。 同样地， 如图 4所示， 当多个基站控制器 44与一个 MSC/VLR45 连接时， 通信*** 400可以有多个 MSC/VLR45 , 则基站控制器 44可以与一 个或多个 MSC/VLR45相连。
在本发明的另一实施例中， 用户设备 40A、 40B与基站 43之间可以通 过 Um接口进行通信。 基站 43与基站控制器 44之间可以通过 Abi s接口进 行通信， 例如， 其物理层连接方式可以为光纤或者其它 （例如 E1 ) 连接方 式。 基站控制器 44与 MSC/VLR45之间可以通过 A接口进行通信， 例如通过 光纤或者其它传输方式进行连接。 MSC/VLR45与 HLR46之间可以通过 C接口 进行通信， 例如通过光纤或者其它传输方式进行连接。 当然， 这些设备之 间还可以通过其它接口或自定义的接口通信， 本发明并不限定。
一般而言， BTS43放置于小区所在地， BSC44以及核心网设备 （例如， MSC/VLR45 , HLR46 ) 放置于相对中心的区域， 便于统一维护和管理。 当小区处于偏远地区时， 例如山区， 荒漠地带， 农村时， 考虑到对于 偏远地区来说， 可能有很大一部分业务只是发生于同一基站下的当地用户 之间的， 例如同村或邻村用户之间的通话、 短信。 而村民和外部用户之间 的业务可能只占整个业务的很小一部分。 当 BTS43和 BSC44间传输中断时， BTS13本身并没有故障， 只是失去了 BSC44的控制。
因此， 为解决 BSC44和 BTS43之间传输距离很远， 如果由于某种原因 造成传输中断后， 所有业务都无法继续的问题。 增加一个附属设备 41， 该 附属设备 41既可以集成在基站 43中， 组成一个新基站， 又可以与 BTS43 连接， 使得 BTS43能够独立的运行， 保证 BTS43覆盖区域下的用户之间进 行通话和短信， 则可能保障 BTS和 BSC之间连接中断时的大部分业务， 有 助于改善偏远地区通信质量。
例如， 所述附属设备 41为实现基站控制器及核心网全部或部分功能的 计算机。
在本发明的另一实施例中， 可能出现多个基站的情况， 每个基站集成 一个附属设备或连接一个附属设备， 还可以是多个基站共同连接一个附属 设备。 多个基站相互连接， 多个基站间用户信息相关共存， 在每个基站中 都保存了多个基站下的用户信息， 多个基站或者附属设备间采用网线互连， 多个基站组成了一个本地管理***。
一般而言， 基站 43支持两种运行模式， 即 Abi s传输正常时的正常模 式和 Abi s传输中断时的单站模式， 并且基站能够自动在两种模式间切换。 其中， 单站模式指 AM s口链路中断后， BTS只和附属设备连接，而不和 BSC 连接的运行模式。
其中， 所述正常模式指基站与基站控制器的接口链路正常时， 基站通 过基站控制器与核心网进行的通信。
所述单站模式为所述基站与附属设备相互配合方式建立主被叫之间的 通信链路， 完成主被叫用户之间的通信。 基站 43处于正常模式时， 基站 43可以作为正常的 GSM***的一部分 运行， 和现有的基站***一致。
在基站 43与基站控制器 44通信出现故障过程中， 当基站 43确定通信 双方用户均在本地管理***覆盖下时， 例如均为该基站 43的本地用户时， 该基站 43与附属设备 41配合完成通信， 其中， 该基站 43与附属设备 41 通信连接， 且所述基站控制器 44以及核心网的功能由所述基站 43和所述 附属设备 41共同实现。
在本发明的另一实施例中， 附属设备 41通过以太网线和基站 43相连， 建立 TCP/IP连接， 附属设备 41和基站 43组成本地管理***。所述基站 43 与附属设备 41也可以集成一起组成一个新基站。
在本发明的另一实施例中， 附属设备 41可以为 PC， 作为人机交互界面 的维护终端。 对基站 43的操作通过附属设备 41进行， 完成用户在本地管 理***中的开户操作， 以及本地管理***的配置、 告警、 话统、 话单等。 在本发明的另一实施例中， 如果受限于基站 43的处理能力， 或为了部署方 便， 基站 43的一些功能也可以部分地由附属设备 41完成。
上述本地管理***， 即可以连接普通的通信网络， 例如 GSM 网络， 又 可以在基站 43或其附属设备 41上运行本地管理***的软件。 本地管理系 统的主要功能是支撑基站在单站模式下的运行。
上述描述的本地管理***对用户的使用不会造成重大的影响。 使用者 可以如使用正常的 GSM***一样使用所描述的本地管理***。
所述用户设备 40A、 40B既可以在同一个基站下， 又可以在同一 BSC下 的不同基站之间进行通话， 但为描述方便， 下述实施例以两个用户设备在 同一个基站下为例进行说明。
一般而言， 基站和附属设备一般可以集成在一起， 承担基站控制器以 及核心网的全部或部分功能， 其中， 部分功能是指根据需要设置的功能， 例如， 如果要进行短信通信， 则基站和附属设备需要承担实现短信通信的 功能， 为描述方便， 基站和附属设备的组成统称为基站。
例如， 基站和基站控制器之间传输中断时， 由基站进行无线资源管理 功能， 能够对无线资源进行分配， 释放， 管理， 以实现基站控制器的功能。
例如， 基站和基站控制器之间传输中断时， 由基站进行短消息解包， 打包， 接收， 转发等功能， 以实现短消息中心的功能。
例如， 基站和基站控制器之间传输中断时， 由基站进行短消息解包计 费等功能， 以实现核心网的功能。
如图 5所示， 为本发明另一实施例的一种通信方法的流程示意图， 结 合图 4和图 5， 该通信方法的过程可以如下所述。
51， 用户设备的 SIM卡同时在核心网和本地管理***开户；
例如， 基站 43管辖的用户设备 40A、 40B的 SIM卡同时在核心网和本 地管理***中开户， 例如将用户信息存储于所述 HLR46和所述本地管理系 统的基站 43， 附属设备 41任意之一， 例如将用户设备 40A、 40B的注册信 息， 例如国际移动用户标识 ( IMSI , International Mobile Subscriber Identity), 电话号码等信息添加到所述 HLR46或所述本地管理***的所述 基站 43， 附属设备 41任意之一。
其中， 上述在本地管理***中开户的用户称为本地用户， 未开户的用 户称为外部用户。 本地用户之间的呼叫称之为本地呼叫， 其余称为外部呼 口 L]。 外部呼叫由基站所连接的 BSC及核心网管理， 在基站和 BSC连接正常 时使用。
52 , 当基站与基站控制器连接正常时， 用户设备正常进行业务， 各种 管理和计费均由基站控制器和核心网控制。
例如， 基站 43与基站控制器 44连接正常时， 基站 43将用户设备 40A、 40B的通信通过基站控制器 44以及核心网的设备，例如 MSC/VLR45与 HLR46 等， 完成通信。
53， 基站和基站控制器的连接中断后， 基站覆盖范围内的用户设备由 本地管理***进行管理和通信。
例如， 基站 43与基站控制器 44的连接中断后， 用户设备 40A、 40B的 通信通过基站 43与附属设备 41配合完成， 其中， 该基站 43与附属设备 41 通信连接， 且所述基站控制器 44的功能由所述基站 43和所述附属设备 41 共同实现。
例如， 所述基站 43， 形式既可以为单个基站， 也可以为基站加上附属 设备， 基站 43具有信道管理、 资源分配、 计费等功能， 基站 43接收主叫 用户 40A按照正常流程发起的短信或语音呼叫请求。
为解决基站在正常模式和单站模式间切换的问题， 基站包括检测单元， 用于检测基站与基站控制器的 Abis口链路是否正常， 例如检测单元周期性 向基站控制器发送检测消息， 收到应答则认为链路正常， 否则认为链路中 断。 当检测单元探测到 Abis链路中断或恢复时， 可以进入单站模式或恢复 成正常模式。
为解决基站在单站模式下运行的问题， 基站和附属设备组成的本地管 理***需要具备以下几种功能： 语音业务相关信令流程处理； 短信业务相 关信令流程处理； 话单管理； 基站维护； 用户管理， 该本地管理***的逻 辑结构可以如图 6所述， 为本发明另一实施例的一种本地管理*** 60的结 例如， 基站和基站控制器之间传输中断时， 由本地管理*** 60进行无 线资源管理功能， 能够对无线资源进行分配， 释放， 管理， 以实现基站控 制器的功能。
例如， 基站和基站控制器之间传输中断时， 由本地管理*** 60进行短 消息解包， 打包， 接收， 转发等功能， 以实现短消息中心的功能。
例如， 基站和基站控制器之间传输中断时， 由本地管理*** 60进行短 消息解包计费等功能， 以实现核心网的功能。
如图 6所示， 该本地管理*** 60可以包括： 模式转化单元 601， 单站 配置单元 603， 用户管理单元 605， 话单管理单元 607， 设备管理单元 609 和业务处理单元 611， 其中， 所述模式转化单元 601， 单站配置单元 603， 用户管理单元 605， 话单管理单元 607， 设备管理单元 609和业务处理单元 611任意组合或全部即可以位于基站， 也可以位于附属设备， 本发明并不限 定。
其中， 模式转化单元 601， 单站配置单元 603， 用户管理单元 605， 话 单管理单元 607， 设备管理单元 609和业务处理单元 611相互通信连接， 图 6仅仅示出各单元具有连接关系， 并不表示就仅仅是该种连接关系， 各个单 元的连接关系， 本发明并不限定。

单站配置单元 603，用于配置和保存基站的配置信息。所述单站配置单 元 603即可以位于基站， 又可以位于附属设备。
正常模式下， BTS的站点及小区配置由 BSC下发给基站。 但当 Abis口 中断后， BTS无法从 BSC获取配置， 出于***自动运行的考虑， 此时不应要 求手动的对 BTS进行配置， BTS必须自身完成配置， 即需要单站配置单元 603用于配置和保存基站的配置信息。
单站配置单元 603保存 BTS的配置信息， 这个配置信息可以是默认配 置信息， 或者保存 Abis口正常时从 BSC获取的配置信息， 例如， 所述配置 信息包括小区的载频个数、 频点、 信道配置、 全球小区标识 （CGI， Cell Global Identification), 发射功率等。 所述单站配置单元 603， 还用于对 配置信息进行修改，例如，用户可以通过图形用户界面（GUI , Graphical User Interface)进行修改，例如通过基站或附属设备的操作界面更改小区频点、 发射功率等。 当 BTS进入单站模式时， 可以使用此配置。
通过本地管理***的配置管理界面， 例如基站或附属设备的配置管理 界面， 基站管理者还可以对单站配置单元 603保存的单站模式下的配置信 息进行修改。 例如， 修改后的配置信息自动替代默认的或从 BSC获取的配 置信息， BTS进入单站模式后， 优先使用手动配置的设置。
为解决本地管理***处在单站模式时， BTS无法和核心网建立联系， 本 地管理***无法从核心网获取用户信息的技术问题， 用户管理单元 605， 用 于完成对需要在本地管理***中注册的用户的开户， 保存开户信息， 当基 站进入单站模式时， 可以为已经在本地管理***中开户的用户提供服务。 例如， 用户管理单元 605用于保存用户的注册信息， 例如 IMSI、 电话号码、 话费余额等信息。
所述用户管理单元 605即可以位于基站， 又可以位于附属设备。
在本发明的另一实施例中， 用户管理单元 605还用于完成用户的话费 记录， 例如完成缴费、 按月扣费等功能。
话单管理单元 607， 用于对基站的话单进行管理， 记录通信信息， 例如 记录通话和短信的信息， 按照固定格式生成话单文件， 并将生成的话单文 件传送给计费*** （未图示）， 以便计费***可以使用话单文件以生成用户 的话费信息。
所述话单管理单元 607即可以位于基站， 又可以位于附属设备。
设备管理单元 609，用于完成对基站或附属设备状态的监控及告警， 例 如 BTS相关的链路状态的显示， 为基站的管理者提供必要的信息。
业务处理单元 611，用于运行本地管理***的基站支持的单站模式和正 常模式。
在正常模式下， 业务处理单元 611的业务处理和普通基站类似。
进入单站模式后， 业务处理单元 611 需要承担基站控制器和核心网的 功能， 例如， 建立通信链路， 完成主被叫用户之间的通信， 例如用于完成 信道资源的管理、 用户的检测、 通讯链路的搭建、 短消息的收发。
较佳地， 所述业务处理单元 611 位于基站， 当然， 也可以位于附属设 备， 本发明并不限定。
例如， 下述以本地管理***处在正常模式和单站模式为例， 说明本地 管理***的工作过程。
如图 7所示， 为本发明另一实施例的一种通信方法流程示意图， 结合 图 6和图 7， 该通信方法可以如下所述。
71， 检测 Abis口连接是否正常；
例如， 检测单元周期性向基站控制器发送检测消息， 如果收到应答则 确定链路正常， 否则确定链路中断。
如果 Abis口连接正常， 进行 73， 否则， 进入 72。
72， 检测基站和附属设备连接是否正常；
当基站和基站控制器的 Abis口连接正常， 进一歩检测基站和附属设备 连接是否正常， 如果正常， 进入 74， 否则， 进入 75。
例如， 检测单元在检测基站和基站控制器的 Abis口连接正常后， 进一 歩检测基站和附属设备连接是否正常， 例如， 检测单元周期性向附属设备 发送检测消息， 如果收到应答则确定链路正常， 否则确定链路中断。 73， 进入正常模式；
当检测单元检测基站和基站控制器的 Abis口连接正常， 不论基站和附 属设备连接是否正常时， 本地管理***均可以工作在正常模式下。 例如， 模式转化单元 601确定基站工作在正常模式下。
在本发明的另一实施例中， 本地管理***还可以包括判断单元， 用于 判断通信双方是否是基站的本地用户。 例如， 该判断单元可以位于基站， 也可以位于附属设备中。 例如， 若主叫用户发起呼叫， 例如， 该呼叫包括 语音和短信， 业务处理单元 611 从主呼信令中获取主叫用户的注册信息， 例如 IMSI , 并传给判断单元， 所述判断单元根据主叫用户的注册信息 （例 如 IMSI )和被叫用户的 IMSI判断所述主叫用户和被叫用户是否为已在本地 管理***开户的本地用户。
例如， 当检测单元检测基站和附属设备连接正常时， 判断单元判断所 述业务处理单元 611传输的主叫用户的注册信息， 例如 IMSI , 是否保存于 所述用户管理单元 605 的用户信息列表中， 如果是， 所述判断单元确定所 述主叫用户是基站的本地用户， 否则， 确定所述主叫用户为非本地用户。
在本发明的另一实施例中， 所述判断单元， 还用于判断被叫用户是否 为本地用户， 例如， 判断单元查询被叫用户的 IMSI是否在本地管理***记 录的在网用户的列表中， 例如查询被叫用户的 IMSI是否保存于所述用户管 理单元 605记录的在网用户的列表中， 如果是， 所述判断单元确定所述被 叫用户是基站的本地用户， 否则， 确定所述主叫用户为非本地用户。
当判断单元判断主叫用户和被叫用户任意之一或两者均是非本地用户 时， 模式转化单元 601 决定本地管理***进入正常模式， 即业务处理单元 611将主呼信令提交给基站控制器，本地管理***和基站控制器及核心网一 起完成呼叫。
在本发明的另一实施例中， 判断单元还判断被叫用户是否处在本地管 理***覆盖下， 例如， 判断单元查询被叫用户的 IMSI是否在本地管理*** 记录的在网用户的列表中。 若被叫用户不在本地管理***覆盖下， 业务处 理单元 611 将主呼信令提交给基站控制器， 本地管理***和基站控制器及 核心网一起完成呼叫。
当判断单元判断主叫用户和被叫用户两者均是本地用户时， 由于基站 与基站控制器的 Abis口连接是正常， 且基站与附属设备的连接也正常， 所 以模式转化单元 601 —般决定本地管理***进入正常模式。 但为节约*** 资源， 在本发明的另一实施例中， 如果被叫用户同时还在本地管理***覆 盖下， 所述模式转化单元 601 可以决定本地管理***进入单站模式， 即在 本地管理***内完成呼叫， 业务处理单元 611 以本地交换的方式建立通信 链路， 完成主被叫用户之间的通信， 话单管理单元 607生成话单。
74， 切换到单站模式；
当基站和基站控制器之间的 Abis链路中断时， 并且基站和附属设备连 接正常时， 本地管理***进入单站模式。
例如， 检测单元检测基站和基站控制器之间的 Abis链路， 以及基站和 附属设备连接是否正常， 当检测单元检测基站和基站控制器之间的 Abis链 路中断， 并且基站和附属设备连接正常时， 模式转化单元 601 决定本地管 理***进入单站模式。
在单站模式下， 本地管理***覆盖下的主被叫双方用户可以通信， 例 如， 本地管理***覆盖下主被叫本地用户之间， 本地用户和外部用户之间， 以及主被叫外部用户之间均可以进行通话， 只要通信双方均在本地管理系 统覆盖下， 其具体过程可以如图 8所述。
75， 通信中断。
当检测单元检测基站和基站控制器之间的 Abis链路中断， 并且检测基 站和附属设备连接中断时， 例如， 附属设备故障时， 由于本地管理***无 法维护， 此时本地管理***回退为普通基站， 通信不能正常进行。
且， 检测单元在通信过程中， 一直检测基站和基站控制器的 Abis链路 是否正常。 Abis接口的检查是循环进行的， 模式转化单元 601根据 Abis接 口状态在正常模式和单站模式间切换。
当检测单元检测基站和基站控制器之间的 Abis链路中断， 并且基站和 附属设备连接正常时， 其工作过程可以如图 8所示， 为本发明另一实施例 的一种通信方法流程示意图。
81， 用户发起呼叫；
例如， 主叫用户发起通话呼叫或短信呼叫， 检测单元检测基站和基站 控制器之间的 Abis链路， 以及基站和附属设备连接是否正常， 当检测单元 检测基站和基站控制器之间的 Abis链路中断， 并且基站和附属设备连接正 常时， 模式转化单元 601决定本地管理***进入单站模式。
82， 检测是否为本地用户；
例如， 若主叫用户发起呼叫， 业务处理单元 611 从主呼信令中获取主 叫用户的注册信息， 例如 IMSI , 并传给判断单元， 所述判断单元根据主叫 用户的注册信息（例如 IMSI )和被叫用户的 IMSI判断所述主叫用户和被叫 用户是否为已在本地管理***开户的本地用户。
例如， 判断单元判断所述业务处理单元 611 传输的主叫用户的注册信 息， 例如 IMSI , 是否保存于所述用户管理单元 605的用户信息列表中， 如 果是， 所述判断单元确定所述主叫用户是基站的本地用户， 否则， 确定所 述主叫用户为非本地用户。
在本发明的另一实施例中， 所述判断单元， 还用于判断被叫用户是否 为本地用户， 例如， 判断单元查询被叫用户的 IMSI是否在本地管理***记 录的用户信息列表中， 例如查询被叫用户的 IMSI是否保存于所述用户管理 单元 605 记录的用户信息列表中， 如果是， 所述判断单元确定所述被叫用 户是基站的本地用户， 否则， 确定所述主叫用户为非本地用户。
当主被叫用户均为本地用户， 且判断单元判断主被叫本地用户均在本 地管理***覆盖下时， 执行 83。如果主被叫用户有至少之一为非本地用户， 即可以结束通信， 又可以进行进一歩判断主被叫用户当前是否均在本地管 理***覆盖下， 执行 85， 具体如下所述。
83， 搭建通话链路， 执行通信过程；
例如， 所述业务处理单元 611 建立主被叫用户之间的通信链路， 完成 主被叫用户之间的通信。
84， 生成话单；
例如， 话单管理单元 607生成话单， 主被叫之间呼叫相关的话单由话 单管理单元 607传送给计费中心， 由计费***进行话费的处理。 其中， 基 站通过 IP组网和计费***相连， 以便传输话单。
85， 用户记录列表是否有记录；
在本发明的另一实施例中， 当主被叫用户有至少之一是外部用户时， 即非本地用户， 判断单元进一歩判断主被叫用户当前是否均在本地管理系 统覆盖下， 例如通过判断用户是否在用户管理单元 605 有用户信息记录。 如果有， 执行 83， 否则通信中断， 结束。
例如， 当外部用户进入本地管理***覆盖区域， 此外部用户发起位置 区更新或选网操作， 其中， 该外部用户即可以是主叫用户， 也可以是被叫 用户。 本地管理***的用户管理单元 605判断其为未知用户， 并记录此外 部用户的信息， 并且为其分配一个移动台国际 ISDN号码 （MSISDN, Mobile Station International ISDN Number ) 0 此外部用户称为临时用户， 判断 单元根据非本地用户的 IMSI 是否在非本地用户的记录列表中判断该非本 地用户是否在本地管理***覆盖下， 例如一个用户的信令上来以后， 业务 处理单元 611获取其 IMSI , 如果 IMSI不在本地用户的记录列表中， 则认为 是非本地用户，同时将此用户记录在所述本地管理***的用户管理单元 605 中。 然后判断单元判断此用户的 IMSI是否已经记录在非本地用户中的记录 列表中， 如果没有， 用户管理单元 605 新增一条非本地用户的记录。 后续 判断单元需要判断用户是不是在本地管理***覆盖下时， 使用 IMSI在记录 中查找。
后续此用户发起呼叫或被呼叫时， 判断单元根据其 IMSI已经记录在用 户管理单元中则可以判断此外部用户在本地管理***覆盖下。
在本发明的另一实施例中， 业务处理单元 611 以短信的形式将新分配 的 MSISDN号码通知该外部用户。
当检测单元检测基站和基站控制器之间的 Abis链路中断， 并且检测基 站和附属设备连接正常时， 且判断单元判断主被叫用户均在本地管理*** 覆盖下时， 所述模式转化单元 601 决定本地管理***进入单站模式， 业务 处理单元 611 以本地交换的方式建立通信链路， 完成主被叫用户之间的通 信， 话单管理单元 607生成话单。
例如， 某主叫用户发起呼叫时， 本地管理***的业务处理单元 611 获 取其 IMSI ,判断单元根据该 IMSI判断该主叫用户是否为本地用户或临时用 户， 若不是， 则呼叫失败。
判断单元查询用户管理单元 605，判断被叫用户是否为本地用户或临时 用户， 若不是， 则呼叫失败。
如判断单元判断主被叫用户为本地管理***覆盖下的本地用户或临时 用户， 业务处理单元 611 以本地交换的方式建立通信链路， 完成主被叫用 户之间的通信， 话单管理单元 607生成话单。
主被叫之间呼叫相关的话单由话单管理单元 607传送给计费中心， 由 计费***进行话费的处理。 其中， 基站通过 IP组网和计费***相连， 以便 传输话单。
且， 检测单元在通信过程中， 一直检测基站和基站控制器的 Abis链路 是否正常。 Abis接口的检查是循环进行的， 模式转化单元 601根据 Abis接 口状态在正常模式和单站模式间切换。
例如， 检测单元检测到基站和基站控制器的 Abis口连接恢复正常时， 切换回正常模式。 例如， 模式转化单元 601 根据所述检测单元检测的基站 和基站控制器的 Abis口连接恢复正常的结果， 将本地管理***单站模式切 换到正常模式。
在本发明的另一实施例中， 本地管理***可以一开始就不考虑连接 BSC, 作为一个小范围覆盖的解决方案实现本地通信。
在本发明的另一实施例中， 本地管理***包括至少一个基站， 多个基 站共同连接一个附属设备， 例如， 两个基站共同连接一个附属设备。 多个 基站间用户信息相关共存， 例如， 在每个基站中的用户管理单元都保存了 多个基站下的用户信息， 多个基站或者附属设备间采用网线互连， 多个基 站组成了一个本地管理***。 但为描述方便， 本实施例以两个基站共同连 接一个附属设备为例进行说明。
例如， 主叫用户接入第一基站， 被叫用户接入第二基站， 第一基站和 第二基站相连。
本实施例的通信过程与图 7所描述的通信过程基本相似， 其不同在于: 本实施例中， 第一基站与主叫用户通信， 例如通信链路的建立和释放， 第 一基站进行资源分配， 计费和管理； 第二基站与被叫用户通信， 例如通信 链路的建立和释放， 第二基站进行资源分配， 计费和管理。 第一基站和第 二基站需要进行消息转发。 至于判断主被叫用户是否是本管理***的用户， 由于每个基站中的用户管理单元都保存了多个基站下的用户信息， 所以， 既可以是第一基站判断主被叫用户是否是本管理***的用户， 也可以是第 二基站判断主被叫用户是否是本管理***的用户， 还可以是各个基站判断 各自所接入的用户是否是本管理***的用户。
通过上述的描述可知， 所述本地管理***， 可以在 Abis口传输中断的 情况下， 作为一个独立的自治***支撑单站覆盖范围内的通信业务， 例如 语音和短信业务， 使得基站和基站控制器失去联系后， 通信业务不会全面 瘫痪。 对于偏远、 传输质量差的地区的通讯提供了保障。
