Description

一种实现紧急呼叫的方法及装置Method and device for realizing emergency call

技术领域Technical field

本文涉及但不限于移动通信技术，尤其涉及一种实现紧急呼叫的方法及装置。This document relates to, but is not limited to, mobile communication technologies, and more particularly to a method and apparatus for implementing an emergency call.

背景技术Background technique

紧急呼叫属于特服呼叫的一种，在实际应用中，紧急呼叫有两种，一种是移动终端(Mobile Station，MS)(例如、手机)发起的以紧急建立(Emergency setup)消息触发的紧急呼叫，一种是MS拨打特定的号码，即特服号码，该号码分析为紧急呼叫业务，两种紧急呼叫类型都是通过在移动交换中心(Mobile Services Switching Centre，MSC)上的配置实现的。An emergency call is a type of special service call. In practical applications, there are two kinds of emergency calls. One is an emergency triggered by an emergency setup message initiated by a mobile station (MS) (eg, a mobile phone). One type of call is that the MS dials a specific number, that is, a special service number, which is analyzed as an emergency call service. Both types of emergency calls are implemented through configuration on the Mobile Services Switching Centre (MSC).

图1是相关技术提供的以Emergency setup消息触发的紧急呼叫处理流程图，如图1所示，包括：FIG. 1 is a flowchart of an emergency call process triggered by an Emergency setup message provided by the related art, as shown in FIG. 1 , including:

步骤101：用户通过MS将Emergency setup消息发送到移动交换中心(MSC)，发起紧急呼叫；Emergency setup消息中携带了紧急呼叫类型(Emergency category)。Step 101: The user sends an Emergency setup message to the Mobile Switching Center (MSC) through the MS to initiate an emergency call; the Emergency setup message carries an Emergency category.

步骤102：MSC根据Emergency category获取紧急呼叫类别，根据位置区信息(Location Area Identification，LAI)获取紧急呼叫索引。Step 102: The MSC obtains an emergency call category according to the Emergency category, and obtains an emergency call index according to the Location Area Identification (LAI).

LAI由移动国家码(Mobile Country Code，MCC)、移动网号(Mobile Network Code，MNC)和位置区域码(Location Area Code，LAC)组成，用来表示一个区域。其中，MCC由国际电信联盟制定，标识全球移动通信***(GSM)公共陆地移动网络(PLMN)所在的国家，其由三个数字组成，如中国为460；MNC由国际电信联盟制定，标识一个国家中的GSM PLMN，由2到3个数字组成；LAC由固定长度的两个16进制的八位数组组成，标识GSM PLMN中的一个位置区，其中0000和FFFE为保留值，在某些特殊情况下表示移动台中不存在LAC，其余值都为合法值。The LAI consists of a Mobile Country Code (MCC), a Mobile Network Code (MNC), and a Location Area Code (LAC) to represent an area. Among them, the MCC is developed by the International Telecommunication Union to identify the country where the Global System for Mobile Communications (GSM) Public Land Mobile Network (PLMN) is located. It consists of three digits, such as China 460. The MNC is developed by the International Telecommunications Union to identify a country. The GSM PLMN consists of 2 to 3 digits; the LAC consists of two hexadecimal octet arrays of fixed length, identifying a location area in the GSM PLMN, where 0000 and FFFE are reserved values, in some special In the case, the LAC does not exist in the mobile station, and the rest of the values are legal values.

步骤103：MSC根据紧急呼叫类别和紧急呼叫索引获取紧急呼叫处理中心的电话号码。 Step 103: The MSC obtains the telephone number of the emergency call processing center according to the emergency call category and the emergency call index.

步骤104：MSC对紧急呼叫处理中心的电话号码进行号码分析，获取号码分析结果。Step 104: The MSC performs number analysis on the telephone number of the emergency call processing center to obtain the result of the number analysis.

步骤105：MSC根据号码分析结果接续呼叫。Step 105: The MSC connects the call according to the number analysis result.

图2是相关技术提供的特服号码分析为紧急呼叫的处理流程图，如图2所示，包括：FIG. 2 is a flowchart of processing a special service number analysis for an emergency call provided by the related art, as shown in FIG. 2, including:

步骤201：用户拨打特服号码；Step 201: The user dials the special service number;

MS通过发送Setup消息到MSC，建立呼叫。The MS establishes a call by sending a Setup message to the MSC.

步骤202：MSC分析该特服号码确定为紧急呼叫，并配置特服群。Step 202: The MSC analyzes that the special service number is determined as an emergency call, and configures the special service group.

步骤203：MSC根据号码分析时配置的特服群和接入信息获取紧急呼叫处理中心的电话号码。Step 203: The MSC obtains the telephone number of the emergency call processing center according to the special service group and the access information configured during the number analysis.

步骤204：MSC分析紧急呼叫处理中心的电话号码，获取号码分析结果。Step 204: The MSC analyzes the telephone number of the emergency call processing center to obtain the number analysis result.

步骤205：MSC根据号码分析结果接续呼叫。Step 205: The MSC connects the call according to the number analysis result.

从上述紧急呼叫的流程可以看出，处理流程需要在每个MSC上配置很多个紧急呼叫索引，特服群等信息；一般情况下，特服群和紧急呼叫关联的紧急呼叫处理中心的电话号码都是相同的，需要配置管理两套数据，存在数据重复，且当MSC的接入信息变动时，需要及时规划紧急相关信息，比较繁琐。It can be seen from the above process of the emergency call that the processing flow needs to configure a plurality of emergency call indexes, special service groups and the like on each MSC; in general, the telephone number of the emergency call processing center associated with the special service group and the emergency call is All of them are the same. Two sets of data need to be configured and managed, and data is duplicated. When the access information of the MSC changes, it is necessary to plan emergency related information in time.

It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

图3是本发明实施例实现紧急呼叫的方法的流程图，如图3所示，步骤包括：FIG. 3 is a flowchart of a method for implementing an emergency call according to an embodiment of the present invention. As shown in FIG. 3, the steps include:

步骤300：移动交换中心(MSC)接收到用户终端发起的呼叫后，判断呼叫是否涉及紧急呼叫。Step 300: After receiving the call initiated by the user terminal, the mobile switching center (MSC) determines whether the call involves an emergency call.

可选的，MSC接收到用户终端发起的呼叫后，获取呼叫的紧急呼叫类型；根据获取的紧急呼叫类型，获取相应的紧急呼叫号码作为被叫号码；查找被叫号码对应的业务类型和紧急呼叫业务键；若所查找到的业务类型是主叫智能增强逻辑的移动网络客户化应用接入非签约方式(OverLay Mo)业务，则确定呼叫涉及紧急呼叫。这里，本发明实施例方法中的紧急呼叫包括日常生活中的报警、火警、急救等紧急呼叫业务。或者，Optionally, after receiving the call initiated by the user terminal, the MSC acquires the emergency call type of the call; obtains the corresponding emergency call number as the called number according to the obtained emergency call type; and searches for the service type and emergency call corresponding to the called number. The service key; if the found service type is the mobile network customized application accessing the OverLay Mo service of the calling smart enhanced logic, it is determined that the call involves an emergency call. Here, the emergency call in the method of the embodiment of the present invention includes an emergency call service such as an alarm, a fire alarm, and a first aid in daily life. or,

MSC收到用户终端发起的呼叫后，获取呼叫的特服号码作为被叫号码，查找被叫号码对应的业务类型和紧急呼叫业务键，若所查找到的业务类型是OverLay Mo业务，则确定呼叫涉及紧急呼叫。本发明实施例方法中的紧急呼叫包括是日常生活中针对拨打特服号码的紧急呼叫业务。After receiving the call initiated by the user terminal, the MSC obtains the special service number of the call as the called number, searches for the service type corresponding to the called number, and the emergency call service key. If the found service type is OverLay Mo service, the call is determined. Involving an emergency call. Emergency call in the method of the embodiment of the invention The call includes an emergency call service for dialing a special service number in daily life.

需要说明的是，OVERLAY包括CAMEL接入非签约方式，当智能网未实现全网漫游智能业务时，可能某一个区域内只提供了若干个具有业务交换点(Service Switch Point，SSP)功能的MSCS。当智能用户漫游到不具有SSP功能的MSCS，其他用户呼叫智能用户时，需要将该呼叫直接路由到指定的具有SSP功能的MSCS，进行智能用户的智能业务触发，这种触发智能业务的方式称为OVERLAY方式。实际应用时，除了上述场景外，也可以将一些特殊的号码分析为OVERLAY业务，其中主叫号码、被叫号码可以分析为按照主叫始发增强逻辑的移动网络客户化应用(Customised Applications for Mobile network Enhanced Logic，CAMEL)签约信息(Originating CAMEL Subscription Information，OCSI)的方式触发智能业务，称为主叫智能OVERLAY业务，即OVERLAY MO；被叫号码可以分析为按照被叫CAMEL签约信息(Terminating CAMEL Subscription Information，TCSI)的方式触发智能业务，称为被叫智能OVERLAY业务，即OVERLAY MT。It should be noted that OVERLAY includes CAMEL access non-contracting mode. When the intelligent network does not implement the full-network roaming intelligent service, only a few MSCSs with Service Switch Point (SSP) functions may be provided in a certain area. . When an intelligent user roams to an MSCS that does not have the SSP function, and other users call the smart user, the call needs to be directly routed to the specified MSS with the SSP function to trigger the intelligent service of the smart user. For the OVERLAY mode. In actual application, in addition to the above scenarios, some special numbers can be analyzed as OVERLAY services, where the calling number and the called number can be analyzed as a mobile network customized application according to the calling origination enhanced logic (Customised Applications for Mobile). Network Enhanced Logic, CAMEL) The triggering information (Ociinating CAMEL Subscription Information, OCSI) triggers the intelligent service, called the calling smart OVERLAY service, that is, OVERLAY MO; the called number can be analyzed as the CAMEL subscription information according to the called (Terminating CAMEL Subscription) Information, TCSI) triggers the intelligent service, called the called intelligent OVERLAY service, that is, OVERLAY MT.

其中，SSP是现有移动网与智能网的连接点，它提供接入智能网功能集的功能，主要完成业务交换功能和呼叫控制功能。Among them, the SSP is the connection point between the existing mobile network and the intelligent network, and provides the function of accessing the intelligent network function set, and mainly completes the service switching function and the call control function.

其中，为了在移动通信***中引入智能网业务，欧洲电信标准研究所(ETSI)于1997年定义了CAMEL。CAMEL的特征是为用户提供一种与服务网络无关的业务一致性，它是一种网络特征而不是补充业务，也就是说，即使用户不在归属公共陆地移动网络(HPLMN)中，CAMEL也可以作为一种手段帮助网络运营者向用户提供特定的业务。Among them, in order to introduce intelligent network services in mobile communication systems, the European Telecommunications Standards Institute (ETSI) defined CAMEL in 1997. CAMEL is characterized by providing users with a service-independent service consistency that is a network feature rather than a supplementary service, that is, CAMEL can be used even if the user is not in the Home Public Land Mobile Network (HPLMN). A means to help network operators provide specific services to users.

步骤301：当MSC判断呼叫涉及紧急呼叫时，触发SCP查找并反馈紧急呼叫所对应的紧急呼叫处理中心的电话号码。Step 301: When the MSC determines that the call involves an emergency call, the SCP is triggered to find and feed back the telephone number of the emergency call processing center corresponding to the emergency call.

The SCP is triggered to search for and feed back the telephone number of the emergency call processing center corresponding to the emergency call.

本发明实施例方法中，SCP是智能网的核心构件。SCP存储用户数据和业务逻辑，其主要功能是接收SSP送来的查询信息并查询数据库，同时，SCP 能根据SSP上报来的呼叫事件启动不同的业务逻辑，根据业务逻辑向相应的SSP发出呼叫控制指令，指示SSP进行下一步的动作，从而实现各种智能呼叫。智能网所提供的所有业务的控制功能都集中在SCP中，SCP与SSP之间按照智能网的标准接口协议CAMEL应用部分(CAMEL Application Part，CAP)进行通信。In the method of the embodiment of the present invention, the SCP is a core component of the intelligent network. The SCP stores user data and business logic. Its main function is to receive the query information sent by the SSP and query the database. At the same time, the SCP Different service logics can be started according to the call event reported by the SSP, and a call control instruction is sent to the corresponding SSP according to the service logic, instructing the SSP to perform the next action, thereby implementing various smart calls. The control functions of all services provided by the intelligent network are concentrated in the SCP, and the SCP and the SSP communicate according to the CAMEL Application Part (CAP) of the intelligent network standard interface protocol.

其中，CAP描述了移动智能网中各个功能实体之间的标准通信规程。Among them, CAP describes the standard communication procedures between various functional entities in the mobile intelligent network.

步骤302：MSC根据SCP反馈的紧急呼叫处理中心的电话号码，将用户终端接续到所查找到的紧急呼叫处理中心。Step 302: The MSC connects the user terminal to the found emergency call processing center according to the telephone number of the emergency call processing center fed back by the SCP.
