Because in the UMTS network, the core net mobile switch equipment can only know that cellphone subscriber's route district or lane place etc. monitor the information in district, promptly know cellphone subscriber's route district and location area information, know cellphone subscriber's location area information at circuit switching (CS) domain core net mobile switch equipment at packet switching (PS) domain core net mobile switch equipment.Therefore core concept of the present invention is based on the route district or the lane place is monitored, be coverage with route district or lane place as the geographic range of monitoring, specified circuit is monitored by all users in district or the lane place.Monitoring system need to determine earlier route district or Location Area Identification and the monitoring attribute thereof monitored, and then with determined information setting in mobile switch equipment, mobile exchange equipments record is also preserved the route district or Location Area Identification and monitoring attribute; Whether when mobile switch equipment carries out voice-and-data when exchange, judging currently provides the user of service to belong to by monitoring route district or lane place, if then report this user's monitoring information and Content of Communication according to route district or lane place monitoring attribute.
The mobile subscriber of UMTS network is monitored based on the route district in the PS territory is example, and the implementation procedure of monitor method of the present invention comprises the steps: as shown in Figure 3
Step 31: monitoring system is determined the target route district of this geographic range correspondence according to the target geographic range of required monitoring, and the sign in target route district and the monitoring attribute determined be set in the mobile switch equipment, that is: send the position and monitor the request of setting to mobile switch equipment.Here, Routing Area Identifier can adopt Routing Area Identifier (RAI, Routing Area).
Step 32: after mobile switch equipment receives that the request of setting is monitored in position that monitoring system sends, write down the quilt described in this request and monitor Routing Area Identifier and relevant monitoring attribute thereof, the route district information that can be used for record request herein, at target route area list of the inner generation of mobile switch equipment.That is to say that mobile switch equipment need generate and safeguard a target route area list, be used to write down which route district and monitored and write down the relevant monitoring attribute that these are monitored the route district.The monitoring attribute here is meant needs to monitor signaling information or voice messaging, and needing to monitor unidirectional voice still is voice of twocouese or the like.
Step 33～34: as certain user, when user A uses the mobile communication service as shown in Figure 3, mobile switch equipment is when providing audio call and exchanges data to continue, initiate the route zone position and monitor handling process, that is: query aim route area list, judge according to the sign in route district under the user A whether this user A drops on by in the scope in intercept target route district, if then mobile switch equipment is reported to monitoring information and the Content of Communication of user A in the monitoring system according to route district monitoring attribute; Otherwise mobile switch equipment only provides communication service to the active user.
In the PS territory or the process described of the monitoring flow process in position-based district, CS territory and above-mentioned steps 31～34 identical, just correspondingly substitute route district in the flow process with the lane place.
Generally speaking, the number of users of conversation can be not a lot of simultaneously in route district or the lane place, monitor little to the performance impact of mobile switch equipment based on the position in route district; But under some extreme case, as when having a match, performing or puting on display, same route district or lane place number of users are more, and mobile switch equipment can be considered the upper limit of specified circuit by the number of users of monitoring simultaneously in district or the lane place limited according to the performance of self.
For instance, suppose current three the route districts that have: route district 1, route district 2 and route district 3, monitoring system is set route district 1 and route district 2 is the target route district of current monitoring, the current route district 2 that belongs to of user A, the current route district 3 that belongs to of user B, the route district monitoring attribute that monitoring system is set is a voice messaging that monitoring users A sends.So, position snoop procedure based on the route district is: monitoring system elder generation is with the sign in route district 1 and route district 2, and only the monitoring attribute of the voice messaging that sends of monitoring users A sends to mobile switch equipment, mobile switch equipment generates a target route area list, has the sign in route district 1 and route district 2 in this tabulation; When user B communicates by letter, mobile switch equipment is when providing service, and the query aim route area list judges whether user B belongs to route district 1 or route district 2, because user B is in the scope in route district 1 and route district 2, then mobile switch equipment does not send out information any to monitoring system.So, when user A communicates by letter, mobile switch equipment query aim route area list, judge whether user A belongs to route district 1 or route district 2, because user A belongs to route district 2, be that user A is being monitored in the geographic range, then mobile switch equipment sends all voice messagings that user A sends to monitoring system when service is provided.
The basic process of monitoring based on the route zone position is realized in step 31～34th, but for validity and the accuracy that improves monitoring, shown in step 35, also can increase the background process process of monitoring system, that is: after monitoring system obtains the monitoring information and Content of Communication of all users in the intended target route district at any time by the monitoring interface from mobile switch equipment, all monitored datas of collecting are analyzed, find out or definite required targeted customer, intercept target user's activity targetedly again.This analytic process can be discerned and separates these data according to targeted customer's phonetic feature; Also can filter communication data, collect effective information according to key feature, such as: by keyword these data are filtered, isolate sensitive information and monitor.Equally, for the process that monitor in the position-based district, the background process shown in monitoring system also can carry out step 35.
In above-mentioned snoop procedure, monitoring system can be upgraded the content that sets at any time, and this renewal comprises: monitor and set and cancellation; In addition, be consistent in order to guarantee the monitored data that sets between monitoring system and the mobile switch equipment, monitoring system can also be inquired about the content of having set as required at any time, comprising: the monitoring attribute that inquiry is set the route district or inquired about certain route district.
Fig. 4 to Fig. 7 has provided respectively and needing between above-mentioned renewal monitoring system and the mobile switch equipment to have realized the signaling process that increases.
