Mobile communications network 101 provides the monitoring access function for monitoring system 102, and monitoring system 102 requires mobile communications network 101 to monitor the communication activity of target UE by monitoring interface 103. When target UE communicated, mobile communications network 101 reported to monitoring system 102 with dependent event and the Content of Communication of communication activity by monitoring interface 103; 102 pairs of monitoring activity of monitoring system manage, and the communication information of collection, storage and evaluating objects subscriber equipment.
In existing monitoring technique standard, the business of practicable monitoring has: speech business, facsimile service, asynchronous data traffic, short message service and supplementary service. In gsm communication system and cdma communication system, requirement provides the equipment of monitoring access function to comprise: attaching position register (HLR, Home Location Register), (MSC of mobile switching centre, Mobile Switch Center) and short message service center (SMC, Short Message Center).
Fig. 2 is the monitoring interface schematic diagram of monitoring system and mobile communications network, as shown in Figure 2, the monitoring system 102 that is positioned at state security department is connected with SMC 204 with the MSC 202 that is positioned at mobile communications network, HLR 203 by X interface 201, realizes the monitoring of the communication activity such as speech business, facsimile service, asynchronous data traffic, short message service, supplementary service to target UE. HLR 203 is connected with SMC 204 with MSC 202 respectively.
Fig. 3 is the monitoring interface structure schematic diagram between monitoring system and MSC, and as shown in Figure 3, the X interface that monitoring system 102 and MSC are 202 comprises: signaling interface X1, business interface X2 and X3. The X1 Interface realization is to the management of monitoring activity, comprises setting, inquiry, cancellation of target UE etc.; X2 interface is to communication activity dependent event and the short message of monitoring system 102 reporting targeted user equipments; The X3 interface is to the Content of Communication of monitoring system reporting targeted user equipment, for example call voice. The transmission bearer of X1 interface and X2 interface is transmission control protocol (TCP)/Internet protocol (IP) or X.25; The transmission bearer of X3 interface is the E1 link.

Fig. 9 is target setting subscriber equipment process chart among the present invention, and as shown in Figure 9, the processing procedure of target setting subscriber equipment may further comprise the steps:
Steps A 1~steps A 2: monitoring system sends target UE to HLR and sets request, and carrying during this target UE is set and asked needs the target UE sign of setting and monitor accordingly parameter; HLR stores the monitoring parameter corresponding with the target setting subscriber equipment after receiving that target UE is set request, then sends target UE to monitoring system and sets response, the executed of notice monitoring system target UE setting operation.
Steps A 3~steps A 4:HLR sends to SMC and monitors parameter setting requests, carries target UE sign and corresponding monitoring parameter in this monitoring parameter setting requests; After SMC receives and monitors parameter setting requests, store the monitoring parameter corresponding with target UE, and to the response of HLR transmission monitoring setting parameter, then according to monitoring parameter the communication activity of respective objects subscriber equipment is monitored, when target UE receive/when sending SMS message, SMC reports short message event and short message to monitoring system.
Steps A 5~steps A 6: if target UE is in open state, HLR sends to service MSC and monitors parameter setting requests, carries target UE sign and corresponding monitoring parameter in this monitoring parameter setting requests; After service MSC receives and monitors parameter setting requests, store the monitoring parameter corresponding with target UE, and to the response of HLR transmission monitoring setting parameter, then according to monitoring parameter the communication activity of respective objects subscriber equipment is monitored, when target UE had communication activity, MSC reported communication activity dependent event and Content of Communication to monitoring system. If target UE is in off-mode, then steps A 5~steps A 6 is omitted.
Figure 10 upgrades among the present invention to monitor the parameter process chart, as shown in figure 10, upgrades the processing procedure of monitoring parameter and may further comprise the steps:
Step B1~step B2: monitoring system sends the target UE update request to HLR, and carrying in this target UE update request needs to upgrade target UE sign and the corresponding current monitoring parameter of monitoring parameter; After HLR receives the target UE update request, store the current monitoring parameter corresponding with target UE, then send target UE to monitoring system and upgrade response, the notice monitoring system is monitored the parameter updating operation executed.
Step B3~step B4:HLR send to monitor parameter updating request to SMC, carries the current monitoring parameter after target UE sign and the renewal in this monitorings parameter updating request; After SMC receives and monitors parameter updating request, delete the former monitoring parameter corresponding with target UE, store the current monitoring parameter corresponding with target UE, and monitor parameter to the HLR transmission and upgrade response, then according to current monitoring parameter the communication activity of respective objects subscriber equipment is monitored, when the targeted customer receive/when sending SMS message, SMC reports short message event and short message to monitoring system.
Step B5~step B6: if target UE is in open state, HLR send to monitor parameter updating request to service MSC, carries the current monitoring parameter after target UE sign and the renewal in this monitorings parameter updating request; After service MSC receives and monitors parameter updating request, delete the former monitoring parameter corresponding with target UE, store the current monitoring parameter corresponding with target UE, and monitor parameter to the HLR transmission and upgrade response, then according to current monitoring parameter the communication activity of respective objects subscriber equipment is monitored, when the targeted customer had communication activity, MSC reported communication activity dependent event and Content of Communication to monitoring system. If target UE is in off-mode, then step B5~step B6 omits.
Figure 11 is that the cancellation target UE is set process chart among the present invention, and as shown in figure 11, the processing procedure that the cancellation target UE is set may further comprise the steps:
Step C1~step C2: monitoring system sends target UE cancellation request to HLR, carries the target UE sign in this target UE cancellation request, and notice HLR cancellation is to the monitoring of target UE communication activity; HLR deletes the monitoring parameter corresponding with target UE after receiving target UE cancellation request, then sends target UE cancellation response to monitoring system, and the notice monitoring system is monitored the executed of parameter deletion action.
Step C3~step C4:HLR sends the parameter cancellation request of monitoring to SMC, carries the target UE sign in this monitoring parameter cancellation request; After SMC receives and monitors parameter cancellation request, delete self storage with target UE to corresponding monitoring parameter, and send to HLR and to monitor parameter cancellation response, stop the monitoring to the activity of respective objects communications of user equipment.
Step C5~step C6: if target UE is in open state, HLR sends the parameter cancellation request of monitoring to service MSC, carries the target UE sign in this monitoring parameter cancellation request; After service MSC receives and monitors parameter cancellation request, delete self storage with target UE to corresponding monitoring parameter, and send to HLR and to monitor parameter cancellation response, stop the monitoring to the activity of respective objects communications of user equipment. If target UE is in off-mode, then step C5~step C6 omits.
When target UE is in off-mode, monitoring system is in HLR during the target setting subscriber equipment, or monitoring system notice HLR is when upgrading the monitoring parameter of the target UE of having set, HLR can't search the MSC at target UE place, namely serve MSC, when target UE is started shooting, after HLR finishes the location register of target UE, initiatively send to service MSC and monitor parameter setting requests. When target UE service MSC changes, after HLR finishes the location register of target UE, initiatively send to the current service MSC of target UE and monitor parameter setting requests.
Figure 12 is process chart when target UE is started shooting among the present invention, and as shown in figure 12, the processing procedure during the target UE start specifically may further comprise the steps:
Owing to before the target UE start, may be monitoring system target setting subscriber equipment in HLR, also may upgrade for monitoring system the monitoring parameter of target UE, so step D1~step D2 can be divided into two kinds of situations of a, b:
Step D1a~step D2a is identical with steps A 1~steps A 2.
Step D1b~step D2b is with step B1~step B2 is identical.
Step D3~step D4: target UE start, target UE carries out location register by service MSC in HLR, after the location register flow process finishes, HLR judges whether the current subscriber equipment that carries out location register is the target UE that monitoring system is set, if so, execution in step D5; Otherwise HLR does not make subsequent treatment.
Step D5~step D6 is identical with steps A 5~steps A 6.
Figure 13 is target UE mobile process chart between MSC among the present invention, and as shown in figure 13, target UE mobile processing procedure between MSC can be divided into two kinds of situations of a, b, specifically may further comprise the steps:
Owing to before target UE moves, may be monitoring system target setting subscriber equipment in HLR, also may upgrade for monitoring system the monitoring parameter of target UE, so step e 1~step e 4 can be divided into two kinds of situations of a, b:
Step e 1a~step e 2a is identical with steps A 1~steps A 2.
Step e 1b~step e 2b is with step B1~step B2 is identical.
Step e 3a~step e 4a is identical with steps A 5~steps A 6.
Step e 3b~step e 4b is with step B5~step B6 is identical.
Step e 5~step e 6: target UE moves to MSC2 by MSC1, service MSC becomes MSC2 by MSC1, MSC2 is current service MSC, target UE carries out location register by MSC2 in HLR, after the location register flow process finishes, HLR judges whether the current subscriber equipment that carries out location register is the target UE that monitoring system is set, if so, and execution in step E7; Otherwise HLR does not make subsequent treatment.
Step e 7~step e 8 is basic identical with steps A 5~steps A 6.
Step e 9~step e 10:HLR sends the parameter cancellation request of monitoring to MSC1, carries the target UE sign in this monitoring parameter cancellation request; MSC1 deletes the monitoring parameter corresponding with target UE of self storing after receiving and monitoring parameter cancellation request, and monitors parameter cancellation response to the HLR transmission. Step e 9~step e 10 can be carried out simultaneously with step E7~step e 8. The current service MSC of target UE is MSC2, is also storing the monitoring parameter corresponding with target UE among the MSC1 as former service MSC, can remove the redundancy of MSC1 kind by step e 9 and 10 two steps of step e. This shows that the purpose of above-mentioned two steps is for the redundancy among the former service MSC that removes the target UE place, namely the MSC except current service MSC deletes the monitoring parameter corresponding with target UE of storing among the former service MSC. Step e 9~step e 10 can be omitted.
Be not that the each location register of service MSC in HLR all can make HLR monitor parameter setting requests or monitor parameter updating request to service MSC transmission, the location register that for example shuts down, the timing position that service MSC does not have to change is registered. Register for the timing position that service MSC does not have to change, HLR should guarantee same service MSC is only upgraded once up-to-date current monitoring parameter, in order to reduce the number of times of information interaction, save system resource, for example, HLR sends up-to-date monitoring parameter to service MSC, when service MSC carries out the timing position registration in HLR, HLR finds that the service MSC of target UE does not change, and sent up-to-date monitoring parameter to this service MSC, so HLR no longer sends the monitoring parameter to this service MSC.
For guaranteeing to only have service MSC just to store the monitoring parameter corresponding with target UE, and avoid monitoring parameter and in service MSC, fall dead, namely monitoring parameter is not eliminated in non-service MSC, for example, target UE shuts down in service MSC1, then the monitoring system cancellation is monitored, and this moment, HLR can not notify the MSC1 deletion monitoring parameter corresponding with target UE because target UE shuts down; Then, target UE is started shooting after moving to MSC2, because the relevant monitoring parameter of this target UE not among this moment HLR, so also can not notify the MSC1 deletion monitoring parameter corresponding with this target UE, then the monitoring parameter of this target UE just is stored in MSC1 forever; If this target UE re-moves to MSC1, this moment, monitoring system did not need the communication activity of this target UE is monitored, but owing to still store the monitoring parameter corresponding with this target UE among the MSC1, so this target UE still can be monitored by MSC1. Therefore, requirement: 1) when target UE shuts down registration, service MSC affiliated during the target UE shutdown deletes the monitoring parameter corresponding with target UE automatically; 2) MSC should be regularly and the uniformity of HLR objects of verification subscriber equipment, for example weekly, has not been eavesdropping target's target UE for those at HLR, and MSC will delete the monitoring parameter of these target UEs.
Above-described target UE is set request, target UE update request and target UE cancellation request, can define separately, also can carry by the target UE operation requests, by the different parameters that in the target UE operation requests, carries, the concrete operations of district office's request; Correspondingly, target UE is set response, target UE upgrades response and target UE cancellation response, can define separately, also can be by target UE operation response carrying.
Above-described monitoring parameter setting requests, monitoring parameter updating request and monitoring parameter cancellation request, can define separately, also can be by monitoring the carrying of parameter operation requests, by in monitoring the parameter operation requests, carrying different parameters, the concrete operations that differentiation is carried out monitoring parameter, for example, can by in monitoring the parameter operation requests, carry the cancellation sign, show and to cancel operation to monitoring parameter; Correspondingly, monitor the setting parameter response, monitor parameter renewal response and monitor parameter cancellation response, can define separately, also can be by monitoring parameter operation response carrying.
Among the present invention, monitoring system and HLR carry out information interaction by monitoring interface, and the definition of this interactive information can be with reference to the prior art standard; In the cdma communication system, when realizing monitoring, information mutual between HLR and MSC, HLR and SMC has been carried out corresponding definition.
