一种通信系统中的监听系统和监听方法Monitoring system and monitoring method in a communication system

技术领域technical field

本发明涉及一种通信系统中的监听系统和监听方法，尤其是一种在通信系统中可以利用一个MSC实现多个区域监听的监听系统和监听方法。The invention relates to a monitoring system and a monitoring method in a communication system, in particular to a monitoring system and a monitoring method which can utilize one MSC to monitor multiple areas in a communication system.

背景技术Background technique

对于通信系统中的监听是必不可少的，现有的通信系统中的监听系统如图1所示，包括监听中心模块(CP)90、接入模块(BB)91、MSC92、协议转换模块(XPTU)93、后台管理器(BAM)94和MSC服务器95。It is indispensable for the monitoring in the communication system, the monitoring system in the existing communication system as shown in Figure 1, comprises monitoring center module (CP) 90, access module (BB) 91, MSC92, protocol conversion module ( XPTU) 93, background manager (BAM) 94 andMSC server 95.

CP90是监控中心，可以下发监听命令和接收相关的监听信息，BB91是监听信息的接入设备，是连接CP90与XPTU的中间设备，提供接入服务，XPTU93是协议转换单元，与BAM94/MSC92属于同一个私网，一般承载于TCP/IP协议，XPTU93与BB91之间采用X.25协议，通过MODEM调制或者承载于E1(1条E1的两个时隙)将X1/X2消息上报到91BB，X1是指通道1，对应于E1上的30时隙，为控制通道，传递控制命令及响应，用于传递BB91的X1命令请求、命令响应以及从MSC92来的告警；X2是指通道2，对应于E1上的31时隙，为数据通道，该系统以固定格式传递对象的监视数据，用于传递交换机侧上报的被控用户的事件(话务事件或非话务事件)；X3是指通道3，承载语音及数据，一般承载于E1线，传递被控用户的语音及数据流。CP90 is a monitoring center, which can issue monitoring commands and receive related monitoring information. BB91 is an access device for monitoring information, an intermediate device connecting CP90 and XPTU, and provides access services. XPTU93 is a protocol conversion unit, which is compatible with BAM94/MSC92 They belong to the same private network and are generally carried by TCP/IP protocol. X.25 protocol is adopted between XPTU93 and BB91, and X1/X2 messages are reported to 91BB through MODEM modulation or carried by E1 (two time slots of one E1). , X1 refers to channel 1, corresponding to 30 time slots on E1, is a control channel, transmits control commands and responses, and is used to transmit X1 command requests, command responses and alarms from MSC92 of BB91; X2 refers tochannel 2, Corresponding to time slot 31 on E1, it is a data channel. The system transmits the monitoring data of the object in a fixed format, and is used to transmit the events (traffic events or non-traffic events) of the controlled user reported by the switch side; X3 refers toChannel 3, carrying voice and data, is generally carried on the E1 line, and transmits the voice and data stream of the controlled user.

因为监听业务具有极强的保密要求，因此一个本地MSC一般服务于一个城市，而且一个MSC只能连接一个CP，即一个城市使用一个CP，管理本城市/地区相关的监听用户，而下一代网络(NGN)的核心网组网方式一般基于大本地网方式，即一个MSC服务器可以为多个城市提供电信通讯服务，而这些城市的监听则需要保持互相独立，即仅管理和监听本城市的监听用户，但是现有XPTU与CP采用的是X.25协议，因此无法实现一台MSC服务器连接多个CP。无法利用一个MSC服务器监听多个CP下的地理区域。Because the interception service has strong confidentiality requirements, a local MSC generally serves a city, and an MSC can only connect to one CP, that is, a city uses one CP to manage the interception users related to the city/region, and the next generation network The (NGN) core network networking method is generally based on the large local network method, that is, one MSC server can provide telecommunications services for multiple cities, and the monitoring of these cities needs to be kept independent of each other, that is, only manage and monitor the monitoring of the city users, but the existing XPTU and CP use the X.25 protocol, so it is impossible to connect one MSC server to multiple CPs. It is not possible to use one MSC server to monitor geographical areas under multiple CPs.

具体实施方式Detailed ways

本发明利用在BAM中的新增模块，实现了利用一个MSC服务器管理多个CP区域下的监听，可以适应下一代NGN大本地网络构架。The present invention utilizes the newly added module in the BAM to realize monitoring under multiple CP areas managed by one MSC server, and can adapt to the large local network framework of the next generation NGN.

如图2所示，为本发明监听系统的结构示意图，包括MSC1和与其连接的数个协议转换单元(XPTU)2，每个XPTU2均连接一个接入模块(BB)3，而每一个BB3又连接有监听中心模块(CP)4，其中的MSC1包括MSC服务器5和BAM6；BAM6用于对MSC进行管理、XPTU2的通信管理和监听中心模块4的连接管理；MSC服务器5用于通信终端的监控、上报和存储监听信息；XPTU2用于协议的转换，BB3为监听信息的接入设备，是连接设备之间的中间件，用于提供接入服务，即与XPTU2对应连接，并且与MSC服务器5相连接，而且CP4可以不利用中间件BB3，而是直接与XPTU2和MSC1直接连接，CP4可以下发监听命令，譬如设置监听数据，通过XPTU2设定到MSC1，还可以接收监听通信终端的语音数据，另外可以接收监听通信终端对象的监听事件(譬如通信终端的位置改变、状态改变、通话过程中的事件，漫游等等)。BAM6中包含互相连接通信模块60和控制模块61，控制模块61和MSC服务器5相连接，通信模块60与所有XPTU2相连接，通信模块60用于MSC和监听中心之间的通信。As shown in Figure 2, it is the structural representation of monitoring system of the present invention, comprises MSC1 and several protocol conversion units (XPTU) 2 connected with it, each XPTU2 all connects an access module (BB) 3, and each BB3 and It is connected with a monitoring center module (CP) 4, wherein MSC1 includesMSC server 5 and BAM6; BAM6 is used to manage MSC, communication management of XPTU2 and connection management ofmonitoring center module 4;MSC server 5 is used for monitoring of communication terminals , Reporting and storing monitoring information; XPTU2 is used for protocol conversion, BB3 is an access device for monitoring information, and is a middleware between connecting devices for providing access services, that is, correspondingly connected with XPTU2, and connected withMSC server 5 CP4 can be directly connected to XPTU2 and MSC1 without using the middleware BB3. CP4 can issue monitoring commands, such as setting monitoring data, setting it to MSC1 through XPTU2, and receiving voice data from monitoring communication terminals. , in addition, it can receive monitoring events of monitoring communication terminal objects (such as communication terminal location changes, state changes, events during a call, roaming, etc.). BAM6 includesinterconnection communication module 60 andcontrol module 61,control module 61 is connected withMSC server 5,communication module 60 is connected with all XPTU2,communication module 60 is used for communication between MSC and monitoring center.

监听中心模块4向对应的XPTU2发送监听命令，XPTU2进行协议转换，并将转换后的信号发送给MSC1，MSC1进行监听并将监听信息发送给监听中心模块4。Themonitoring center module 4 sends a monitoring command to the corresponding XPTU2, the XPTU2 performs protocol conversion, and sends the converted signal to the MSC1, and the MSC1 monitors and sends the monitoring information to themonitoring center module 4.

本系统将XPTU2拉远，每个城市设置一个XPTU2，BB3和XPTU2采用X.25协议，但因为是一对一的关系；各XPTU3与BAM6采用远程的TCP/IP连接。XPTU2将X1/X2消息上报到BB3，X1是指通道1，用于传递BB的X1命令请求、命令响应以及从MSC来的告警；X2是指通道2，用于传递MSC侧上报的被控用户的事件(话务事件或非话务事件)；X3是指通道3，承载语音及数据，一般承载于E1线，传递被控用户的语音及数据流。This system pulls XPTU2 far away, and sets up one XPTU2 in each city. BB3 and XPTU2 adopt X.25 protocol, but because it is a one-to-one relationship; each XPTU3 and BAM6 adopt remote TCP/IP connection. XPTU2 reports the X1/X2 message to BB3. X1 refers to channel 1, which is used to transmit BB’s X1 command request, command response and alarm from MSC; X2 refers tochannel 2, which is used to transmit the controlled user reported by MSC side Events (traffic events or non-traffic events); X3 refers tochannel 3, which carries voice and data, generally carried on E1 line, and transmits the voice and data streams of the controlled user.

因此本系统实现了一个MSC服务器接入多个CP，利用一个MSC服务器管理多个城市，监听要求各城市的监听信息管理分别独立，互不影响，即一个城市的CP可以只管理本城市/地区相关的监听用户，并不知道该MSC服务器下其它城市的监听数据。这种作法既体现了用户的要求，也符合监听的保密要求。Therefore, this system implements one MSC server to access multiple CPs, and uses one MSC server to manage multiple cities. The monitoring requires that the monitoring information management of each city is independent and does not affect each other, that is, the CP of a city can only manage the city/region The relevant monitoring users do not know the monitoring data of other cities under the MSC server. This approach not only reflects the requirements of users, but also meets the confidentiality requirements of monitoring.

如图3所示，为本发明通信系统中的监听方法的流程图，As shown in Figure 3, it is a flow chart of the monitoring method in the communication system of the present invention,

步骤101，与MSC相连接的监听中心模块发出监听命令，该监听命令包括需要监听的通信终端号码信息；Step 101, the monitoring center module connected to the MSC sends a monitoring command, which includes the communication terminal number information to be monitored;

监听命令的发出具体为与MSC相连接的监听中心模块通过第一通道，或者监听中心模块利用BB通过第一通道发出监听命令；The issuing of the monitoring command is specifically that the monitoring center module connected to the MSC passes through the first channel, or the monitoring center module uses BB to issue a monitoring command through the first channel;

步骤102，该监听命令经过协议转换单元进行协议转换后，通过后台管理器发送给MSC服务器；Step 102, the monitoring command is sent to the MSC server by the background manager after the protocol conversion unit performs protocol conversion;

步骤103，MSC服务器对所述通信终端进行监控，获得该通信终端的语音信息和监听事件；Step 103, the MSC server monitors the communication terminal, and obtains voice information and monitoring events of the communication terminal;

步骤104，MSC服务器将所述监听事件通过后台管理器发送给所述监听中心模块；所述语音信息发送给所述监听中心模块或者利用BB发送到所述监听中心模块。Step 104, the MSC server sends the monitoring event to the monitoring central module through the background manager; the voice information is sent to the monitoring central module or sent to the monitoring central module through BB.

BAM在原来的XPTU通讯管理的基础上新增对多CP的TCP/IP连接管理功能，BAM侧提供CP台号分配，而且这个台号也唯一标识一个XPTU，BAM与MSC服务器的通讯协议(X1和X2的消息)中新增CP台号域，对于语音的X3输出，MS服务器可以通过数据配置路由到不同的BB/CP来实现；Based on the original XPTU communication management, BAM adds the TCP/IP connection management function for multiple CPs. The BAM side provides CP station number allocation, and this station number also uniquely identifies an XPTU. The communication protocol between BAM and MSC server (X1 The CP station number field is added in the message of X2), and for the X3 output of the voice, the MS server can be routed to different BB/CP through data configuration to realize;

在控制模块中存储一个维护表：Store a maintenance table in the control module:

  连接句柄connection handle  CP台号CP station number  状态 state  TCP/IP的SOCKET句柄值TCP/IP SOCKET handle value  台号可以固定也可以动态分配The station number can be fixed or dynamically allocated  是否在线/离线Whether online/offline

上述的维护表是一种维护和对应形式，其实可能的描述和对应方法和很对，只要能提供CP台号管理就可以了。The above-mentioned maintenance table is a form of maintenance and correspondence. In fact, the possible description and correspondence methods are quite correct, as long as the CP station number management can be provided.

控制模块分配CP台号，这里可以加入最大连接数的控制，维护SOCKET连接与CP台号的对应关系，CP/BB侧往交换机的方向上的请求根据句柄换算成CP台号，通过BAM转发到交换机。交换机往CP/BB侧方向的数据流通过CP台号获取对应的SOCKET连接句柄转发到对应的CP或BB；The control module assigns the CP number. Here, the control of the maximum number of connections can be added to maintain the corresponding relationship between the SOCKET connection and the CP number. The request from the CP/BB side to the switch is converted into a CP number according to the handle, and forwarded to switch. The data flow from the switch to the CP/BB side is forwarded to the corresponding CP or BB through the CP station number to obtain the corresponding SOCKET connection handle;

因此步骤102详细流程如图4所示，包括如下步骤：Therefore, the detailed process ofstep 102 is as shown in Figure 4, including the following steps:

步骤201、该监听命令经过协议转换单元进行协议转换后，发送给后台管理器的通信模块；Step 201, the monitoring command is sent to the communication module of the background manager after the protocol conversion unit performs protocol conversion;

步骤202，通信模块将该监听命令发送给控制模块，查询该监听中心模块对应的SOCKET连接句柄；Step 202, the communication module sends the monitoring command to the control module, and queries the SOCKET connection handle corresponding to the monitoring center module;

步骤203，控制模块根据该SOCKET连接句柄换算成该监听中心模块的台号。Step 203, the control module converts the station number of the monitoring center module according to the SOCKET connection handle.

MSC对监听数据的处理要以CP台号组织，即哪些通信终端被哪个CP台监听，则后续的监听事件和第一通道的响应就报往哪些CP，对于语音的输出，MSC服务器可以通过数据配置路由到不同的BB/CP来实现。MSC's processing of monitoring data should be organized by CP station number, that is, which communication terminals are monitored by which CP station, and the subsequent monitoring events and the response of the first channel will be reported to which CPs. For voice output, the MSC server can pass data Configure routing to different BB/CP to achieve.

因此如图5所示，步骤104中对于监听通信终端监听到的监听事件的发送具体为：Therefore, as shown in FIG. 5, instep 104, the sending of the monitoring event monitored by the monitoring communication terminal is specifically as follows:

步骤301，MSC服务器将所述监听事件和该监听中心模块的台号发送给后台管理器的控制模块；Step 301, the MSC server sends the monitoring event and the station number of the monitoring center module to the control module of the background manager;

步骤302，该控制模块查询该监听中心模块台号对应的SOCKET连接句柄；Step 302, the control module queries the SOCKET connection handle corresponding to the station number of the monitoring center module;

步骤303，根据SOCKET连接句柄该控制模块利用通信模块通过第二通道将监听事件发送给协议转换模块；Step 303, according to the SOCKET connection handle, the control module uses the communication module to send the monitoring event to the protocol conversion module through the second channel;

步骤304，该协议转换模块将该控制信息发送给所述监听中心模块，或者通过BB发送给所述监听中心模块。Step 304, the protocol conversion module sends the control information to the monitoring central module, or sends it to the monitoring central module through the BB.

而语音信息的传输为MSC服务器移动交换机将呼叫接续过程中的放音以及通话语音等语音信息发送给所述监听中心模块或者利用BB发送到所述监听中心模块。The transmission of the voice information is that the MSC server mobile switch sends voice information such as playback and conversation voice in the call connection process to the monitoring center module or utilizes BB to send to the monitoring center module.

因此本发明的监听方法实现了一个MSC管理多个CP区域的监听。Therefore, the monitoring method of the present invention realizes the monitoring of multiple CP areas managed by one MSC.
