Description
Technical field
The present invention relates to the monitoring technique field of mobile radio communication, refer to especially a kind of method of inserting audiomonitoring system into mobile communication network.
Background technology
The mobile radio communication of all operations, comprise that global system for mobile communications (GSM:Global System for Mobile Communication), code division multiple access system (CDMA:Code Division Multiple Access) and following broadband CDMA system (W-CDMA:Wide Code Division Multiple Access) all must provide the monitoring access interface, so that monitoring system is linked into the monitoring that realizes in the mobile radio communication the targeted customer.
The business that can monitor in the existing monitoring technique standard has: speech business, facsimile service, supplementary service and short message service. In mobile radio communication, provide the equipment of monitoring access function to have: mobile switching centre (MSC:Mobile Switching Centre), attaching position register (HLR:Home Location Register), short message service center (SMC:Short Message Center) etc. All provide the equipment of monitoring access function to be referred to as Telecommunication network equipment. Monitoring system then is that to monitor interface be the boundary, to all and the general name of monitoring relevant device beyond the Telecommunication network equipment.
Figure 1 shows that the relational model between monitoring system and the mobile radio communication. Mobile radio communication provides the monitoring access function for monitoring system, and monitoring system is monitored targeted customer's activity by monitoring the interface requirement mobile radio communication. When the targeted customer has communication activity, mobile radio communication is with the dependent event of communication activity, the event that produces when being feeling the pulse with the finger-tip mark telex network activity, for example, start, shutdown, calling, ring, reply, switch, release, position upgrades, and Content of Communication is to need the content transmitted in the feeling the pulse with the finger-tip mark telex network activity, for example, call voice, short message, grouped data are reported to monitoring system by monitoring interface. Monitoring system is responsible for the management of monitoring activity, collects simultaneously, the information of storage and evaluating objects User Activity.
Figure 2 shows that the Monitor scheme schematic diagram for the CDMA net of prior art. Link to each other by monitoring interface between monitoring system and MSC, HLR and the SMC equipment, security and confidentiality in order to improve monitoring activity adopt private line access between monitoring system and the mobile radio communication.
Figure 3 shows that the monitoring interface model figure of prior art. The monitoring interface comprises: signaling interface and business interface, and wherein, signaling interface namely illustrates the X1 interface, realizes the management to monitoring activity, and business interface namely illustrates X2 and X3 interface, realizes reporting targeted customer's activity description. Business interface is divided into two kinds of business interface X2 and business interface X3 according to the difference that reports content, and business interface X2 is used for reporting the dependent event of targeted customer's communication activity, and business interface X3 only is used for reporting targeted customer's voice communication content. The transmission bearer of signaling interface X1 and business interface X2 is ICP/IP protocol or agreement X.25, and the transmission bearer of business interface X3 is the E1 link.
Figure 4 shows that the monitoring interface model figure between monitoring system and HLR or the SMC Telecommunication network equipment. Because the event that HLR reports only has the communication activity dependent event, namely start shooting event, shut down event, supplementary service Action Events and supplementary service registering events etc., the event that SMC reports only has the short message event, therefore, only has X1 and X2 interface in the monitoring interface of monitoring system and HLR and SMC.
In mobile radio communication, MSC mainly realizes the monitoring to speech business, and the portfolio of monitoring is relatively many, and HLR and SMC realize the dependent event of communication activity and the monitoring of short message, and the portfolio of monitoring is less.

When the monitoring system in a certain area need to be by the strange land HLR, SMC or HLR and SMC when monitoring the targeted customer, can only entrust local monitoring system to implement monitoring to this targeted customer.
There is following significantly shortcoming in such scheme:
1) all Telecommunication network equipments must provide and have the special line physical interface of monitoring access function, and particularly for the existing equipment of online operation, needing increases new hardware even equipment, uses for private line access. Therefore cause the increase of Telecommunication network equipment cost.
2) to provide more special line to be used for connecting Telecommunication network equipment and monitoring system, increase the construction cost of monitoring system.
3) because certain regional monitoring system only links to each other with the Telecommunication network equipment of this area usually, therefore, can't implement the monitoring to the strange land targeted customer, thereby cause the scope of its monitoring activity to be subject to region limits.
