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 parameter accordingly; After HLR received that target UE is set request, storage and the corresponding monitoring parameter of target setting subscriber equipment sent target UE to monitoring system then and set 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, storage and the corresponding monitoring parameter of target UE, and to the response of HLR transmission monitoring parameter setting, according to monitoring parameter the communication activity of respective objects subscriber equipment is monitored then, when target UE receive/when sending SMS message, SMC reports short message incident 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, storage and the corresponding monitoring parameter of target UE, and to the response of HLR transmission monitoring parameter setting, according to monitoring parameter the communication activity of respective objects subscriber equipment is monitored then, 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 monitors the parameter process chart for upgrading among the present invention, 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 received the target UE update request, storage and the corresponding current monitoring parameter of target UE sent target UE to monitoring system then and upgrade response, and 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, deletion and the corresponding former monitoring parameter of target UE, storage and the corresponding current monitoring parameter of target UE, and to the response of HLR transmission monitoring parameter update, according to current monitoring parameter the communication activity of respective objects subscriber equipment is monitored then, when the targeted customer receive/when sending SMS message, SMC reports short message incident 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, deletion and the corresponding former monitoring parameter of target UE, storage and the corresponding current monitoring parameter of target UE, and to the response of HLR transmission monitoring parameter update, according to current monitoring parameter the communication activity of respective objects subscriber equipment is monitored then, 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 sets process chart for cancellation target UE 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; After HLR received target UE cancellation request, deletion and the corresponding monitoring parameter of target UE sent target UE cancellation response to monitoring system then, 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 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 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, promptly serve MSC, when target UE is started shooting, after HLR finishes the location registers of target UE, initiatively send and monitor parameter setting requests to service MSC.When target UE service MSC changes, after HLR finishes the location registers of target UE, initiatively send and monitor parameter setting requests to the current service MSC of target UE.
Process chart when Figure 12 starts shooting for target UE among the present invention, 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 the monitoring parameter of target UE for monitoring system, 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 registers by service MSC in HLR, after the location registers flow process finishes, HLR judges whether the current subscriber equipment that carries out location registers is the target UE that monitoring system is set, if, 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, the processing procedure that target UE moves 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 the monitoring parameter of target UE for monitoring system, 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 registers by MSC2 in HLR, after the location registers flow process finishes, HLR judges whether the current subscriber equipment that carries out location registers is the target UE that monitoring system is set, if, 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; After MSC1 receives and monitors parameter cancellation request, delete self storage with the corresponding monitoring parameter of target UE, and send to HLR and to monitor parameter cancellation response.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 and the corresponding monitoring parameter of target UE among the MSC1 as former service MSC, can remove the redundant information 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 redundant information among the former service MSC that removes the target UE place, i.e. MSC except that current service MSC, delete store among the former MSC of service with the corresponding monitoring parameter of target UE.Step e 9～step e 10 can be omitted.
Be not that the each location registers of service MSC in HLR all can make HLR monitor parameter setting requests or monitor parameter updating request to service MSC transmission, the location registers of for example shutting 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 have only service MSC just to store and the corresponding monitoring parameter of target UE, and avoid monitoring parameter and in service MSC, fall dead, promptly monitoring parameter is not eliminated in non-service MSC, for example, target UE shuts down in service MSC1, the monitoring system cancellation is monitored then, and this moment, HLR can not notify MSC1 deletion and the corresponding monitoring parameter of 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 MSC1 deletion and the corresponding monitoring parameter of 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 and the corresponding monitoring parameter of 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 and the corresponding monitoring parameter of target UE automatically; 2) MSC should be regularly and the consistency 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, differentiation is to monitoring the concrete operations that parameter is carried out, for example, can show and to cancel operation to monitoring parameter by in monitoring the parameter operation requests, carrying the cancellation sign; Correspondingly, monitor the parameter setting response, monitor the parameter update 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.
