  • MDT Minimization of Drive Test
  • Requirements needed to enhance MDT user consent include that “user consent is given to the operator so that the 3GPP system can be provisioned/ configured based on the operator-subscriber agreed permissions stored in UDM to make it feasible for the 3GPP system to comply with local laws and regulations.”
  • Operators operate in different jurisdictions, where each jurisdiction may prescribe different rules for the application of consent, for example the information or uses of information that should be governed by user consent.
  • User consent procedures can enable the operators to configure their networks with appropriate checks to allow/disallow the processing (and dissemination) of specific information governed by consent, as determined by local regulation or by the choice of the operator.
  • the RAN checks user consent only for cases of management based MDT.
  • the gNB-CU-CP shall select the suitable UEs for MDT data collection. If the UE is not in the specified area or if the serving PLMN is not within the Management Based MDT PLMN List the UE shall not be selected by the gNB-CU-CP for MDT data collection. Therefore, it is valuable to clarify that some descriptions are only valid for the case of management based MDT.
  • the 0AM configures the RAN with rules that instruct the RAN on whether user consent needs to be checked for collection and reporting of a specific type of information/data of a subscriber for a particular purpose. In other words, the OAM tells the RAN which MDT measurements are governed by user consent and for such measurements the RAN needs to check if the user did or did not provide user consent.
  • the OAM configures the RAN (or functions within the RAN) with a list of MDT measurements for which the RAN is not requested to check the user consent provided by the users.
  • the RAN can check the Management Based MDT configuration against these measurements and if the MDT measurements in the management based configuration appear in the list configured by the OAM, the RAN deduces that the measurements can be collected without the presence of user consent.
  • the OAM chooses not to configure the RAN for user consent check for M6: Packet delay measurement; or M7: Packet loss rate measurement, the reason being that local laws and regulations do not consider such measurements to be sensitive. In this case, the RAN would not need to check if user consent was given when collecting M6 and M7 measurements and when distributing such measurements to the TCE.
  • the OAM configures the RAN to not perform user consent check for one (or more) MDT measurements.
  • the AMF For signaling based MDT, it is the AMF that checks whether user consent is in place. For example, the AMF starts a trace session and sends a TRACE START message to the gNB. The AMF shall consider the MDT user consent information when activating an MDT trace session for the UE.
  • the OAM configures the AMF with information indicating whether user consent is required for a specific type of MDT measurement, so to enable the AMF to check whether, upon receiving a Signaling Based MDT configuration for a given UE from the OAM, any of the measurements included in the MDT configuration are subject to user consent and therefore whether triggering a Trace Activation towards the RAN, to activate the Signaling Based MDT configuration towards the UE, is subject to presence of user consent from the user associated to the UE or not.
  • the AMF receives information about the MDT measurements subject to user consent via signaling from the RAN. Namely, once the RAN is configured by the OAM about the MDT measurements that are subject to user consent, or equivalently of the MDT measurements that ae not subject to user consent, the RAN can signal such list of measurements to the AMF for example over the NG interface. [0113] In additional or alternative embodiments, for the case of signaling based MDT, the 0AM configures the AMF in relation to the MDT measurements for which check on user consent is not needed at the AMF.
  • the AMF Upon receiving a signaling based MDT configuration, the AMF skips the user consent check for the MDT measurements, if the list of Signaling Based MDT measurements is not subject to user consent, as per configuration received by 0AM.
  • the 0AM updates its configuration as the RAN and at the AMF, for measurements that are subject to user consent, or equivalently that are not subject to user consent, in case such list of measurements changes in time.
  • the RAN and AMF shall deduce that all measurements are subject to user consent.
  • the 0AM configures the RAN with rules concerning the MDT measurements that can be collected and distributed to the TCE. Taking the example of configuration of measurements that are subject to user consent, MDT measurements not listed in such 0AM configuration can be collected by the RAN and reported to the TCE without consent from the user. In additional or alternative embodiments, the 0AM configures the RAN with MDT measurements which can be configured without user consent check at the RAN.
  • the 0AM configures the AMF with rules concerning the MDT measurements that can be collected by the RAN and distributed to the TCE.
  • the AMF can trigger a Trace Activation towards the RAN and the RAN can collect the MDT measurements and report them to the TCE without consent from the user.
  • the 0AM configures the AMF with MDT measurements which can be configured without user consent check at AMF.
  • the 0AM has configured the RAN with a list of MDT measurements that require user consent.
  • the RAN receives from the AMF the Management Based MDT PLMN List IE, which indicates that the UE gave consent for the measurements subject to user consent.
  • the 0AM signals to the NG-RAN a Management Based MDT configuration.
  • the RAN shall select UEs on the basis of the received user consent information represented by the Management Based MDT PLMN List IE.
  • the RAN does not need to consider user consent when selecting UEs. Namely, the RAN can select also UEs for which the Management Based MDT PLMN Lis was not received.
  • the 0AM has configured the AMF with a list of MDT measurements that require user consent.
  • the AMF signals to the NG- RAN, on a per UE basis, and separately from the Trace Activation procedure, the Signaling Based MDT PLMN List IE, which specifies the PLMNs where MDT can be collected.
  • the 0AM signals to the AMF a Signaling Based MDT configuration.
  • the AMF shall trigger a Trace Activation for the UE.
  • the AMF shall trigger a Trace Activation even if user consent is not available for the UE.
  • the trace Activation IE shall include the Signaling Based MDT PLMN List IE in order to enable the RAN to configure the UE with a list of PLMNs, needed to cany out logged MDT measurements, as described below.
  • the Signaling Based MDT PLMN List IE is optionally included in the Trace Activation IE, and therefore it cannot currently be assumed that the CN will always signal it to the RAN. Indeed, as per current specifications, the CN determines that there is no user consent for the user associated to the UE involved in the Signalling Based MDT process, the CN currently does not signal the Signalling Based MDT PLMN List IE.
  • the AMF can always retrieve a PLMN List to signal to the RAN as Signaling Based MDT PLMN List. This is possible because the CN can retrieve from the subscriber database the information in FIG. 7.
  • the UDM (subscriber's database in 5G) includes two separate IES, one for MDT user consent and another for the MDT Allowed PLMN List. Therefore, if the AMF (CN) retrieves these parameters from the UDM, the AMF can use them to construct and to signal the Signaling Based MDT PLMN List IE to the RAN. Such Signaling Based MDT PLMN List IE can be derived from the mdtAllowedPlmnldList retrieved from the UDM.
  • an MDT PLMN List (namely the plmn- IdentityList over RRC), which describes where the UE can collect and report logged MDT measurements, can be signaled to the UE for the following two reasons.
  • the MDT PLMN List indicates to the UE the list of PLMNs where measurements can be collected and reported to the TCE because the user gave consensus.
  • the MDT PLMN List shall still be signalled to the UE, but in this case this list only indicates to the UE the PLMNs where these MDT measurements should be collected and reported, independently of user consent.
  • One way to overcome this problem is to modify TS 37 320 to state: “A UE is configured with an MDT PLMN List if user consent is valid for the RPLMN, or if the data types of the configured MDT measurements are not subject to user consent.”
  • an MDT configuration includes measurements that are not subject to user consent
  • the UE can still be configured with an MDT PLMN List.
  • the UE in this case will report logged MDT measurements accordingly to the configured PLMN List.
  • the above UE behavior cannot currently be achieved because the Management/Signaling Based MDT PLMN List may not be signaled to the RAN by the CN. Namely, in today's solution, if a user did not give consensus for MDT measurement collection, the Management/Signaling Based MDT PLMN List may not be signaled from to the RAN.
  • the some embodiments proposes that, if the RAN receives a Management Based MDT configuration including measurements that are not subject to user consent, and if the RAN has not received from the CN the Management Based MDT PLMN List, the NG-RAN can configure the UE with a MDT PLMN List, namely with the plmn-IdentityList over RRC, which is derived at the RAN.
  • the NG-RAN derives the MDT PLMN List based on the PLMNs the UE can access. This information is known to the RAN by means of the Mobility Restriction List received from the CN. Hence the plmn-IdentityList can be derived on the basis of the Mobility Restriction List.
  • the NG-RAN derives the MDT PLMN List based onf the PLMN List included in the Management Based MDT configuration received by the RAN node.
  • the NG-RAN derives the MDT PLMN List by means of operator provided policies which are configured to the RAN and that spell out the list of PLMNs that should be included in the plmn-IdentityList.
  • the CN always signals the Signaling Based MDT PLMN List to the RAN, either as an independent IE (e.g., as part of UE context setup/update procedures) or included in the Trace Activation IE.
