4.3.1 Activation of measurement collection job in UTRAN

In Signalling based activation, the QoE measurement collection is sent to the UE from the OAM via CN. The messages from EMS propagated to HSS, MSE Server/SGSN and RNC. QoE measurement collection activation request is propagated to UE.

When HSS activates the QoE measurement collection for a job, the MSC Server/SGSN can send the QoE measurement collection to the UE through RNC, the following configuration parameters shall be included in the message: serviceType, areaScope, qoECollectionEntityAddress, pLMNTarget, qoETarget, qoEReference and QMC configuration file.

1) The NM sends activateAreaQMCJob to DM/EM that controls the impacted RNC(s), and includes the parameters: serviceType, areaScope, qoECollectionEntityAddress, pLMNTarget, qMCTarget, Individual UE Id, qoEReference and QMC configuration file.

2) The DM/EM sends activateAreaQMCJob to HSS that controls the impacted RNC(s), and includes the parameters: serviceType, areaScope, qoECollectionEntityAddress, pLMNTarget, qoETarget, Individual UE Id,qoEReference and QMC configuration file.

3) The HSS sends an Insert Subscriber Data to the MSC Server/SGSN that is registered in the HSS in a previous Update Location Request message.

4) The MSC Server/SGSN starts finding the UE and check if that the UE capability matches the criteria for ServiceType in activateAreaQMCJob

5) The MSC Server/SGSN sends message CN INVOKE TRACE to the RNC and includes the parameters: serviceType, areaScope, qoECollectionEntityAddress, pLMNTarget, qoETarget,qoEReference and QMC configuration file.

6) The RNC checks for connections where the UE has the UE Application Layer Measurement Capability that match the criteria for serviceType in the activateAreaQMCJob.

7) The RNC start a UE request session and stores the associated QoECollectionEntityAddress, sends the message RRCConnectionReconfiguration to the UE, and includes the following: serviceType, qoEReference and QMC configuration file.

8) The access stratum in the UE sends the AT command +CAPPLEVMC to application level and includes the following: serviceType, qoEReference and QMC configuration file.

9) When the application in the serviceType starts, the QMC is initiated.

10) The application layer sends the AT command +CAPPLEVMR including a recording session indication that a session has started to the access stratum.

11) The UE sends the message MeasurementReport including the recording session indication to the RNC.

12) The RNC sends a notification including the recording session indication to the NM.

13) When the QMC is completed, the recorded information is collected in a QMC report, including qoEReference and recordingSessionId. The qoEReference, Client Id, in the reporting container (that represent the UE request session), and recordingSessionId are needed in the QMC collection entity for post processing purposes.

14) The application layer sends the AT command +CAPPLEVMR including qoEReference and the QMC report to the access stratum.

15) The UE sends the message MeasurementReport including qoEReference and the QMC report to the RNC.

16) The RNC sends the QMC report to the MCE associated to the qoEReference.

4.3.3 Deactivation of measurement collection job in UTRAN

4.3.3.1 Pre-set time has elapsed in UTRAN

When the pre-set time is elapsed, the HSS or SGSN and the RNC sets the network request session to ended, but do not delete the UE request session id and the Collection Entity Address parameters [3], due to that reports still can come from the UE that has to be transferred to the collection centre. The UE request session id and the Collection Entity Address parameters [3] are deleted when the session is ended.

4.33.2 Forced deactivation in UTRAN

If the operator technician or the management application wants to deactivate a measurement collection job, the management system sends the deactivateQoEJob operation [3] to the HSS or SGSN, that propagate it to the RNC. The RNC sets the network request session to ended, but does not delete the UE request session id and the Collection Entity Address parameters [3], as the UE still may send reports which shall be send to the collection centre. For UE request sessions which have reported that a recording session is started, the RNC sends the MeasurementControl message [4] with the DeactivateJob request to relevant UEs. The Access stratum sends +CAPPLEVMC AT command [5] to the application with the DeactivateJob request. The application stops the recording session and stops recording of the requested information. The UE request session id and the Collection Entity Address parameters [3] in the RNC are deleted when the UE request session is ended.
