Description

一种紧急号码匹配方法及匹配装置 技术领域
本发明涉及移动通信技术领域，尤其涉及一种紧急号码匹配方法及匹配装置。
背景技术
在日常生活中，移动终端的使用者可能会遇到一些情况(例如天然灾害、车祸事故、抢劫等)，需要通过移动终端拨打本地紧急号码列表中的紧急号码来寻求帮助。目前，对于紧急电话号码的辨识通常是将一组固定的紧急号码列表储存于终端系统内，如匪警，火警，救护等，当使用者拨出的号码落在该紧急号码列表内时，无论终端当时处于什么状态(如键盘锁、无SIM卡、无服务等)，终端系统皆会允许拨出紧急号码并尝试连接紧急电话服务。
终端内的紧急号码列表来源于三个部分：第一部分来自于终端注册的移动网络所下发的紧急号码；第二部分来自终端设备中插入的用户标识模块(SIM，Subscriber Identity Module)卡上预先携带的紧急号码；第三部分来自终端自身预置的紧急号码。目前，绝大多移动网络均已不再向注册本网络的终端下发紧急号码，而且很多运营商所发布的SIM卡中也不会携带紧急号码，因此，目前终端内的紧急号码列表中绝大部分都是由终端自身预置的紧急号码来组成，而且终端自身预置的紧急号码能够在没有插入SIM卡或者服务受限时仍旧可以进行拨打。
全球不同国家或地区的紧急号码是不相同的，终端自身所预置的紧急号码通常根据终端的发售地来进行预置，例如：在中国发售的手机会预置110(匪警)，119(火警)，120(急救)等紧急号码；而在美国发售的手机会预置911报警号码；在英国发售的手机会预置999报警号码；在德国发售的手机会预置110(匪警)，112(火警)等紧急号码；在印度发售的手机会预置100(匪警)，101(火警)，102(急救)等紧急号码。
各国紧急号码各不相同，而且配置也不一致。同样是110，在中国是紧 急号码，但是在其他国家可能是运营商服务号码，不可以视为紧急号码进行处理。
一般来说，当移动终端在进行国际漫游时，采用目前的紧急号码的配置方法就会造成移动终端无法拨打漫游地的紧急号码，例如，移动终端从中国漫游至印度时，移动终端拨打119无法接通印度的火警电话。这可能会对移动终端用户的人身和财产造成无法弥补的损害。

实现本发明的最佳方式
以下根据图1～图6，具体说明本发明的较佳实施例。
移动终端可以各种形式来实施。例如，本发明中描述的终端可以包括诸如移动电话、智能电话、笔记本电脑、数字广播接收器、个人数字助理(PDA)、 平板电脑(PAD)、便携式多媒体播放器(PMP)、导航装置等等的移动终端，本领域技术人员将理解的是，除了特别用于移动目的的元件之外，根据本发明的实施方式的构造也能够应用于固定类型的终端。
移动终端在开机后，会自动进行网络搜索和初始化，通过基站连接通信系统，所述的通信系统可为采用时分多工接入(Time Division Multiple Access，TDMA)的全球移动通讯系统(Global System for Mobile Communications，GSM)、通用封包无线服务系统(general packet radio service，GPRS)或GSM增强数据率演进系统(enhanced data rates for GSM evolution，EDGE)，也就是我们俗称的2G网络。或者，所述的通信系统还可为采用宽带码分多址接入(Wideband Code Division Multiple Access，WCDMA)的通用移动电信系统(Universal Mobile Telecommunications System，UMTS)，也就是我们俗称的3G网络。或者，所述的通信系统还可为采用正交频分多工(orthogonal frequency-division multiplexing，OFDM)及/或正交频分多址接入(orthogonal frequency-division multiple access，OFDMA)的长期演进系统(Long Term Evolution，LTE)(如3GPP Rel-8/9/10标准)、先进长期演进系统(LTE-Advanced，LTE-A)(如3GPP Rel-11标准)或先进长期演进系统的后继者，也就是我们俗称的4G网络。所述的通信系统并不局限于上述所列，任何可以为移动终端提供通信服务的系统都包含在本发明的通信系统的范围内。
GSM和WCDMA都是基于GSM-MAP核心网，GSM网络可以平滑演进到WCDMA系统。目前欧洲、亚洲、非洲有很多国家已经建立WCDMA系统。所谓的WCDMA和GSM之间的国际漫游是指GSM(或者WCDMA)用户漫游到国外的WCDMA(GSM)网络，利用拜访地WCDMA(GSM)网络来为其提供业务服务。
由于各个国家发展的情况存在一定的差异，例如有的国家只存在GSM网络(比如中国)，而有的国家则只建设了WCDMA网络(例如日本)，而没有GSM网络。为此3GPP TS 22.100规范指出，WCDMA终端应该可以支持通过GSM的SIM卡来访问WCDMA网络。当然此时WCDMA网络只能为用户提供GSM系统所能提供的那些业务(WCDMA的特有业务，例如视频、高速数据通信无法提供)。用户是否可以通过GSM的SIM卡来访问WCDMA 网络由该WCDMA网络运营商控制。同时3GPP TS 22.101规范指出UMTS系统应该允许WCDMA用户通过GSM终端来访问GSM网。
通用集成电路卡(UICC，Universal Integrated Circuit Card)是一种可移动智能卡，它用于存储用户信息、鉴权密钥、电话簿、短消息等信息。在GSM和3GPP规范中，用户想正常的使用各种业务都必须依靠移动终端中的UICC卡。如果移动终端中没有UICC卡，那么用户只能使用紧急呼叫业务(例如110、119)。UICC卡是定义了物理特性的智能卡的总称，UICC卡可以包含多种逻辑应用，例如用户标识模块(SIM，Subscriber Identity Module)、通用用户标识模块(USIM，Universal Subscriber Identity Module)，还可以包含其它应用(电子钱包等)。
SIM卡是GSM网络中移动终端所使用的智能卡，它用于存储各种参数和相关用户信息，例如用户签约信息、鉴权密钥、用户的优选信息、以及短信息。SIM卡中包含下列信息：1、国际移动用户标识(IMSI，International Mobile Subscriber Identity)：用户身份标识，用于接入鉴权。2、移动用户ISDN号码(MSISDN，Mobile Subscriber ISDN Number)：移动用户的手机号码3、密钥Ki、加密算法A3、A8，用于鉴权4、移动国家码(MCC，Mobile Country Code)、归属PLMN的移动网络码(MNC，Mobile Network Code)：网络标识。
USIM卡用于WCDMA网络中，用于存储用户签约信息、鉴权信息、付费方式、用户短消息等。USIM卡中包含下列信息：1、国际移动用户标识(IMSI，International Mobile Subscriber Identity)：IMSI是分配给每个用户的唯一标识，该标识对用户来说是不可见的，而对网络来说是可见的。IMSI作为用户标识用于鉴权目的。在IP多媒体子系统(IMS，IP Multimedia Subsystem)中其私有用户标识等价于IMSI。2、移动用户ISDN号码(MSISDN，Mobile Subscriber ISDN Number)：在该域中存储了分配给用户的一个或者多个电话号码。在IMS中其公共用户标识等价于MSISDN。3、加密密钥(CK，Cipher Key)和完整性密钥(IK，Integrity Key)：这些密钥用于空中接口中数据的加密和完整性保护。USIM单独存储在电路域和分组域使用的密钥。4、短消息(SMS，Short Message Service)：USIM可以存储短消息以及相关的数据，例如发送者、接收者、状态等。5、短消息参数：该 域用于存储与SMS业务有关的配置数据，例如SMS中心地址、支持的协议等等。6、多媒体消息业务(MMS，Multimedia Message Service)用户连接性参数：该域用于存储与MMS业务相关的配置数据，例如MMS服务器地址、MMS网关地址。7、MMS用户优选信息：该域用于存储与MMS业务有关的用户优选信息，例如发送报告标志、优先级、到期信息等。
相对于SIM卡的单向鉴权(网络鉴权用户)，USIM卡鉴权机制采用双向鉴权(除了网络鉴权用户外，用户也鉴权网络)，有很高的安全性。与SIM卡电话薄相比，USIM卡电话薄中每个联系人可以对应多个号码或者昵称。相对SIM卡机卡接口速率，USIM卡机卡接口速率大大提高(230kbps)。相对SIM卡对逻辑应用的支持，USIM可以同时支持4个并发逻辑应用。
目前UICC卡一般同时包括USIM和SIM两个模块，此时称为复合USIM卡(它可以兼容GSM终端和WCDMA终端)，如果UICC中只包括USIM模块，那么称为纯USIM卡。WCDMA终端在机卡接口上具备后向兼容性，兼容USIM卡(复合USIM卡和纯USIM卡)和GSM的SIM卡。GSM终端兼容GSM的SIM卡和WCDMA的复合USIM卡，不兼容纯USIM卡。WCDMA双模终端无论插入SIM卡或者USIM卡(复合USIM卡或者纯USIM卡)都可以接入GSM无线网络或者WCDMA无线网络。GSM终端插入SIM卡或复合USIM卡只能接入GSM无线网络。SIM卡可以应用于GSM、WCDMA、TD-SCDMA系统中。USIM卡可以应用于GSM、WCDMA、TD-SCDMA系统中。
通信系统的基站会发出广播系统消息，广播系统消息中包含MIB(Master Information Block，主信息块)、SB(Scheduling Block，调度块)、SIB(System Information Block，系统信息块)三种。其中主信息块MIB中包含PLMN(Public Land Mobile-communication Network，公众陆地移动网络)信息，该公众陆地移动网络PLMN是由政府或它所批准的经营者为公众提供陆地移动通信业务目的而建立和经营的网络，每个运营商的网络都有对应的PLMN号码进行标识，而公众陆地移动网络PLMN ID由两部分组成，即移动国家码MCC(mobility country code)以及运营商码MNC(Mobile Network Code)，MCC国家码可以唯一标识一个国家。
本发明通过移动终端注册的网络来获取国家码(MCC)，然后匹配当地 的紧急号码，这样便能使得移动终端在不同国家获取到正确的当地紧急号码，并且使得移动终端在短暂脱网或开启飞行模式等情况下，也可以匹配到正确的紧急号码，保证了紧急号码与国家的正确匹配。

移动终端在漫游到印度并注册登记到印度当地的通信网络后，已经获取了印度的国家码，并将紧急号码列表和PLMN列表更新为印度的紧急号码和印度的PLMN ID信息，当移动终端用户根据中国的紧急号码拨打匪警电话110时，由于移动终端无卡，无法注册登记到通信网络中，则移动终端驻留到搜索到的通信网络中，提取模块获取当前通信网络的PLMN ID信息，处理模块将存储模块中的PLMN列表更新为当前的PLMN ID信息，提取模块进一步从PLMN ID信息中提取所在国家的国家码MCC，作为当前国家码，确定使用与印度的国家码对应的印度的紧急号码列表，紧急号码确定模块判断用户拨打的紧急号码110与当前的印度紧急号码列表中的紧急号码不一致，紧急号码确定模块进一步确定移动终端用户拨打的110紧急号码与中国国家码对应的紧急号码列表中的匪警号码一致，则紧急号码确定模块锁定印度的紧急号码列表中对应的匪警号码为100，呼叫模块自动拨打100紧急号码。
本发明通过获取移动终端注册登记的通信网络的国家码来获得与国家码相匹配的紧急号码列表，而当移动终端无卡时，移动终端驻留到搜索到的通信网络，获得该通信网络的公共陆地移动网络信息PLMN ID，从公共陆地移动网络信息中获得国家码，根据国家码查询紧急号码映射表获得与国家码相 匹配的紧急号码列表，当移动终端无卡且无法使用无线通信功能时，移动终端采用上一次注册登记或驻留通信网络时获得的国家码查询紧急号码映射表获得与国家码相匹配的紧急号码列表。本发明保证了移动终端在任何情况下都可以获得正确的国家码，从而得到与国家码相匹配的正确的紧急号码，保证了移动终端在国际漫游时可以准确拔打紧急号码。本发明实现简单，便于普及，具有很广阔的适用范围。
尽管本发明的内容已经通过上述优选实施例作了详细介绍，但应当认识到上述的描述不应被认为是对本发明的限制。在本领域技术人员阅读了上述内容后，对于本发明的多种修改和替代都将是显而易见的。因此，本发明的保护范围应由所附的权利要求来限定。
