Discuss as was explained briefly above, defined in the specification of 3GPP versions 10 minimum drive test (MDT).In MDT, from The measurement of UE collections can be referred to as MDT daily records or MDT data.

UE tracking generally refers to from one or more UE obtain the information of the such as network information.MDT can be general tracking The part of operation.According to some embodiments, follow-up mechanism can be used for obtaining MDT data.

The application-specific entity for being referred to as tracking collection entity (TCE) can be used for storing the tracking/MDT data for gathering (also referred to as Record for MDT or keep track of).TCE can be application-specific entity or can be incorporated in another entity.TCE can be included for depositing The database of storage tracking/MDT records.Multiple TCE can be coexisted in identical network, and can be in tracking/MDT tasks Activationary time selects the TCE of specific tracking session.Selected TCE can keep fixing for whole tracking process.

Some features of MDT defined in version 10 include：UE includes positional information as UE radio measurement reports Part ability；And UE records the ability of Radio Measurement during the idle condition of UE.

In network share environment (such as in those environment described in 3GPP TR32.851), multiple operators can be with Shared identical eNB/RNC.In this scene, identical eNB/RNC can service the difference for belonging to shared identical RAN resources Multiple users of operator.

In the MDT tasks based on region, eNB/RNC gathers MDT information from multiple (may own) active users.Then The information (directly or indirectly) of collection is sent to into TCE.

Identical eNB/RNC can be subordinated to multiple users of different operators and gather information as identical MDT tasks Part.Each operator can be identified by PLMN ID (public land mobile network identifier).Each operator can have Limit the different privacy policies of the access to any sensitive MDT data.

Therefore, present inventor have determined that, operation based on the eNB/RNC of the MDT tasks in region be required to it is shared should The correct operator of eNB/RNC assigns gathered data (for example, MDT data).Using for each tracing task configuration Single TCE (as current standardized), it is in practice impossible that such data are assigned.

Fig. 4 illustrates the present case based on the MDT in region.According to the example of Fig. 4, only select to belong to single operator UE is used for MDT tasks.The MDT data of the UE from the second shared operator is not gathered completely.

Referring more particularly to Fig. 4, Operations, Administration and Maintenance system (OAM) is shown at 450.Show at 405 by The shared eNB of multiple operators' (being in this example operator A and operator B).Show at 404 and belong to operator A's One or more UE.The UE for belonging to operator B is shown at 404.The TCE of operator A is shown at 452.Show at 454 The TCE of Chu Liao operators B.

In step S1, by being sent to the message of shared eNB 405 from OAM systems 450 MDT is activated.In the example In, (MDT tasks) message package is activated containing so that and/or causing eNB 405 that the information of MDT data is obtained from the UE of operator A. In some embodiments, this can be from the instruction of the do so of OAM.MDT circulates in shown generally at 456.

Activation circulates in shown generally at 458.In the activation circulation, as shown in step s 2, shared eNB 405 " activation " message is sent to one or more UE of operator A 401.This notifies those UE：Shared eNB 405 needs MDT to survey Amount.

As shown in step S3, their report measurement is sent back shared eNB 405 by the UE of operator A.Then in step Rapid S4, shared eNB 405 creates the tracking file comprising metrical information, and metrical information is MDT data.In step S5, by this Tracking file is sent to the TCE of operator A 452 from shared eNB 405.Then MDT data is stored in into operator A 452 TCE in.These measurements can at any time be obtained as needed by operator.It should be appreciated that in some instances, tracking File can also include the other information in addition to MDT data.

It should be noted that in the example of fig. 4, it is no to obtain any measurement from the UE of operator B.Therefore, quilt is not measured It is sent to the TCE of operator B.

Fig. 5 shows the latency development of Fig. 4 scenes using the instant MDT based on region.In the example of hgure 5, it is MDT The UE of task choosing Liang Ge operator.But, because being currently only tracking/MDT tasks configures a TCE, it is all with Track daily record is only transmitted to an a TCE, is in this case the operator for initiating tracking/MDT tasks.Therefore, the scene is not Meet the expectation of other operators, and also may potentially invade the hidden of the UE of unsatisfied (unfulfilled) operator Private (because the potential sensitive data from their collections is exposed to other operators).This scene is likely to violate and possibly transports The specific user of battalion business agrees to.

This will be more fully described with reference to Fig. 5.

As shown in step S1, OAM systems 550 to " activation " that shared eNB 505 sends the beginning for indicating MDT tasks disappears Breath.The message includes the information for causing eNB to obtain the MDT related to the UE of operator A and operator B.Message at step S1 Can include obtaining the instruction of such measurement.

In step S2, shared eNB 505 sends " activation " message (in this example, MDT tasks to the UE of operator A Initiated by operator A).In step S3, activate message is also sent to the UE of operator B 504.Therefore, the UE of operator A and The notified MDT tasks of UE of operator B are movable, and they need to report back to measurement.

In step S4, the UE measurements of operator A 501 send back shared eNB 505.It is shared in step S5 ENB 505 creates tracking file for these measurements for receiving, and is sent to operator A's by file is tracked in step S6 TCE 552。

In step S7, the measurement that the UE of operator B 504 is reported is sent to shared eNB 505.In step S8, it is These measurements create tracking file, and in step S9, tracking file are sent to into the TCE of operator A.

In some instances, single tracking file can be used for the MDT numbers retrieved from the UE of operator A and operator B According to.

Therefore, in this example, the TCE 552 of operator A can store the UE of both operator A and operator B with Track file.Tracking file can be individually received on the basis of " per operator ", or as an alternative, eNB can be comprising next TCE is sent the data to from one or more tracking files of the MDT data of the mixing of operator A and the UE of operator B 554.In certain embodiments, eNB can create a file with each UE.It should be appreciated that the TCE 554 of operator B does not connect Receive any tracking file.It is also understood that due to being stored at the TCE of operator A (and therefore can be visited by operator A Ask), the privacy of the UE of operator B may be invaded.

Fig. 6 illustrates such example, wherein the TCE for aiming at operator A tracking/MDT days gathered from the UE of operator B Place is identified, is then dropped or is transmitted to the TCE of operator B.

In more detail, in step S1, OAM systems 650 send activate message to start MDT tasks to shared eNB 605. In step S2, shared eNB 605 to the UE of operator A 601 sends activate message, and in step S3 to operator B 604 UE send activate message, to notify the UE of operator A and operator B：MDT is needed to measure.

In step S4, shared eNB 605 will be sent to from the measurement of the UE of operator A 601.In step S5, share ENB create these measurement tracking file, it is sent to the TCE 652 of operator A in step S6.

In step S7, the UE measurements of operator B 604 are transmitted to shared eNB 605.Create in step S8 and track File, it is sent to the TCE 652 of operator A in step S9.

As discussed above, in order to alleviate safety problem, the TCE of operator A can abandon relative with the UE of operator B The tracking file answered, as shown in step S10.As an alternative, as shown in step S11, the TCE 652 of operator A can by with operation The UE of business B 604 associated tracking file is transmitted to the TCE 654 of operator B.

If it will thus be appreciated that the measurement from the UE of only a single operator is used to measure (such as so as not to violate Any privacy requirement), then can reduce can from its obtain measurement UE number, it can reduce certainty of measurement.The opposing party Face, if using the measurement of the UE from multiple operators, there may be privacy concern, because according to Current standards, these Measurement needs to be only sent to the TCE of an operator.

Fig. 7 is shown from 3GPP TSG-RAN WG3 meetings number 84；The MDT based on signaling of R3-141228 is illustrated.Should System show MDT servers 760, home subscriber servers (HSS) 762, Mobility Management Entity (MME) 764, participate in and The eNB 705 shared between trusteeship and operation business and UE 701.The TCE for participating in operator is illustrated at 752, and trustship is transported The TCE of battalion business is illustrated at 754.

In step S1, MDS servers to HSS 762 sends trace session activation message.Then, in step S2, HSS to MME 764 sends " insertion subscriber data " message.Then, in step S3, MME 764 sends that " tracking is opened to shared eNB 705 Begin " message.Then, in step S4, share eNB 705 and send MDT configuration message, MDT configuration message informing UE to UE 701 701 start MDT measurements.In step S5, then the MDT daily records of collection are sent to shared eNB 705 by UE 701.

Step S6 and S7 are alternative steps, and are not all implemented as the part of same procedure.In step S6, share ENB 705 will keep track of and be sent to the TCE 752 for participating in operator.As an alternative, as shown in step S7, sharing eNB 705 will Track record is sent to the TCE 754 of trusteeship and operation business.That is, track record is sent to TCE 752 or TCE 754, And not both.

In this example, it is illustrated that in the MDT (wherein only selecting a UE) based on signaling, which fortune belonged to regard to UE Battalion business and set (collective) daily record will be sent to where (TCE IP address argument bags of MDT tracing tasks configuration Address containing required TCE), it is very clear and definite.That is, as described above, in the figure 7, towards " participate in operator TCE " and The alternative path of tracking data is shown towards two arrows of " trusteeship and operation business TCE ", and is configured based on TCE IP address Parameter is selecting particular path.It is, in the MDT based on signaling for selecting single UE, its " owner " operator is Know, and the TCE of the operator is configured to it is manifestly intended that being the part of tracking/MDT tasks.This mechanism is not suitable for Select the MDT based on region of multiple UE.

According to embodiment, the MDT tasks based on region in network share environment support the data record to multiple TCE (logging).In order to support the data record to multiple TCE in single tracing task, strengthen tracing task configuration to have Multiple TCE addresses.This makes it possible to the TCE by each of which is sent to for the tracking file of the UE of different operators.In reality In applying example, the maximum number of the TCE addresses of each MDT task is not less than the maximum number of the operator of shared network element, net Network element such as eNB/RNC.Current standards specify that each network element less than six operators, therefore should be implemented at some In example, each MDT tasks configuration is no less than six TCE addresses.

TCE addresses are associated with operator.In certain embodiments, this by each TCE address by being linked to mark fortune The specific PLMN ID of the network of battalion business are realizing.In certain embodiments, create the MDT's for record using additional configurations Mapping table between TCE ID and TCE addresses.The table can be that the MDT of record is specific.The table can also be strengthened so that for Each entry, the PLMN ID of related operators are added.Therefore, strengthened TCE by also including PLMN (carrier ID) row ID is mapped to the table of TCE addresses (for example, IP address).It is, for example possible to use look-up table makes TCE ID, TCE addresses and PLMN Association between ID.

Figure 10 A to 10C show the example of the such mapping table according to some embodiments.

The table of Figure 10 A includes the row 1070 for TCE ID, the row 1072 for corresponding TCE IP address and is used for The row 1074 of TCE PLMN.

The table of Figure 10 B includes the row 1070 for TCE ID and the row 1074 for TCE PLMN.

The table of Figure 10 C includes the row 1072 for TCE IP address and the row 1074 for TCE PLMN.

It will thus be appreciated that the identity for indicating TCE of Figure 10 A to 10C or address to the TCE operator (i.e. TCE PLMN) identity mapping.

It should be understood, of course, that in embodiment, these row and columns will be filled appropriate value.These tables can also be can be more New.For example, when TCE is added and removed respectively, can add or remove row.Can also be by adding or removing row come more New any table.For example, table 10A can be updated by removing row 1072 so that it is then similar to table 10B (vice versa). Table 10A can be updated by removing row 1070 so that it is then similar to table 10C (vice versa).

MDT data collection can be divided into two classes (record and instant).In instant MDT, eNB activates connected UE Measurement, and these UE directly report each measurement.In the MDT of record, eNB is activated to the MDT tasks of the record of UE, Then UE enters idle (disconnection) pattern, and starts collection measurement, and measurement is stored in local file.When comprising such When the UE of file enters activity/connection mode, this document is transmitted to eNB.For security reasons, UE is not allowed to know record MDT files are by the IP address of the TCE being transmitted to.Therefore, eNB must safeguard the TCE identity (UE of the MDT tasks of log Known No. TCE) to journal file by the mapping table of the TCE IP address being transmitted to.

Can remove/discharge will be used to tracking/UE the selectional restrictions of MDT tasks to the PLMN only having with track reference The current standardized constraint that the UE of the rPLMN (PLMN of registration) that ID matches is selected, to promote multiple TCE concepts.This can be with Allow to carry out UE selections using the rPLMN matched with any TCE PLMN.According to embodiment, each MDT and tracing task have There is the existing parameter in Section of 5.9 Plays of 3GPP TS32.422, it is referred to as tracking the IP address of collection entity.In reality In applying example, the tracing task parameter is extensible to allow multiple TCE (each rPLMN ID) and indicates to be associated with given TCE addresses Particular operator/PLMN.Then, for each TCE, the single tracking text of the track record of the PLMN comprising matching is created Part.May then based on PLMN ID and each track record file is sent to into correct TCE.

Fig. 8 shows first embodiment.System include OAM systems 850, shared eNB 805, the UE 801 of operator A, The TCE 854 of the UE 804 of operator B, the TCE 852 of operator A and operator B.

Fig. 8 is referred again to, in step S1, OAM systems 850 send " activation (MDT tasks) " and disappear to shared eNB 805 Breath.As briefly discussed, activation (MDT tasks) message includes the identifier of related operators TCE.These identifiers can Being PLMN ID.It is, in this example, activation (MDT tasks) message will indicate operator A's to shared eNB 805 The PLMN ID of the TCE 854 of TCE 852 and operator B.It should be appreciated that each operator can have more than one PLMN, because This can be configured with more than two TCE to PLMN tuples for two shared operators (such as) in activation parameter.

In step S2, shared eNB 805 sends " activation (measurement) " message to the UE 801 of operator A, and in step Rapid S3 also sends activation (measurement) message to the UE 804 of operator B.The UE of operator A and B is notified respectively in step S2 and S3 Start recording is measured.

In step S4, shared eNB 805 receives report measurement, and is this in step S5 from the UE 801 of operator A A little measurements create tracking file.In step S6, tracking file is sent to shared eNB 805 TCE 852 of operator A.Fortune Then the TCE 852 of battalion business A can store the tracking file in memory.

In step S7, the UE of operator B sends its report measurement to shared eNB 805, and in step S8, it is shared ENB 805 creates tracking file for these measurements.In step S9, shared eNB 805 sends to the TCE 804 of operator B For the tracking file of the UE of operator B.Then the TCE 854 of operator B can store the tracking file.

It will thus be appreciated that in the embodiment in fig. 8, the TCE 852 of operator A is had been received by only with operator A's UE related tracking file, and the TCE 854 of operator B has been received by only related to the UE of operator B tracking file. Therefore, privacy can be mitigated according to the present embodiment to consider.

Fig. 9 shows another embodiment.Fig. 9 shows OAM systems 950, shared eNB 905, the UE of operator A 901st, the signaling between the UE 904 of operator B, the TCE 952 of operator A and the TCE 954 of operator B.

In step S1, " configuration (TCE-PLMN) " message is sent from OAM systems 950 to shared eNB 905.Namely Say, in this embodiment, via OAM rather than via tracking IRP PLMN ID are configured." configuration " sent in step S1 disappears Breath includes indicating the configuration attribute for associating of TCE addresses and particular operator (PLMN ID).

In step S2, " activation (MDT tasks) " message is sent from OAM systems 950 to shared eNB 905.

In step S3, activation (measurement) message is sent to the UE 901 of operator A, and in step S4, from shared eNB 905 to operator B UE 904 sends activation (measurement) message.These " activation " message informing UE starts to perform measurement.

In step S5, from the UE 901 of operator A report measurement is received.Then, in step S6, create for these measurements Tracking file.Then, in step S7, the shared marks of eNB 905 should be sent to the TCE of the tracking file.This can be with example Such as by using by the look-up table of the PLMN cross-checks of the UE of operator A TCEs corresponding to its completing.Then, in step S8, Tracking file is sent to into identified TCE, is in this case the TCE 952 of operator A.

In step S9, report measurement is received from the UE 904 of operator B at shared eNB 905.Then, in step S10, tracking is created at shared eNB 905 for these measurements.In step S11, shared eNB 905 is for example used again The look-up table that the UE of operator B is associated with the TCE 954 of operator B is identifying the TCE that should be sent to of these measurements. Then, in step S12, the tracking file that will be used for the UE of operator B is sent to the TCE 954 of operator B, and wherein file can be with Storage is in memory.

It will thus be appreciated that in the embodiment in fig. 9, privacy and/or security consideration can be mitigated again, because category The TCE of respective operator is only sent in the tracking file of the UE of certain operator.

In the embodiment of Fig. 8 and Fig. 9, when eNB/RNC decide whether to select particular UE (for example, for Cell tracing or MDT based on region) and whether start for it keep track of session when, eNB/RNC check UE belong to which PLMN (one In a little embodiments, this is completed by checking the rPLMN of UE).Once eNB/RNC determines PLMN ID, then by the PLMN and TCE PLMN is compared.If UE PLMN match TCE PLMN, the UE can be selected for tracking/MDT tasks, and can So that correct track record will be distributed to from the information of the record of the UE.Track record can only be linked to a PLMN ID.Then track record (or tracking file) can be sent to by corresponding TCE according to TCE to PLMN mappings.

Therefore it should be understood that the embodiment of both Fig. 8 and Fig. 9 enables MDT data to be sent in a secured manner Multiple TCE.

In certain embodiments, " activation (MDT tasks) " message is received at shared eNB can cause network measure The initiation of operation.In other embodiments, the initiation of network measure operation can be single.In the embodiment in fig. 9, step S1 is considered pre-configured form, i.e., wherein TCE-PLMN information is sent to shared eNB.The step of Fig. 8 S1 and The step of Fig. 9 S2 be considered it is equivalent because " activation (MDT tasks) " message can specify that is used for using which TCE Data acquisition.The step of Fig. 8, S1 can also deliver the information of the possessory PLMN of TCE.That is, swashing for Fig. 8 can be strengthened (MDT tasks) message living is with by the multiple TCE of multiple PLMN carryings.Because pre-configured step in step sl (is wherein configured TCE-PLMN), S2 can activate the information in (MDT tasks) the step of Fig. 9.Step S2 in Fig. 9 still may be used To carry the information (for example, TCE ID and/or TCE IP address etc.) of one or more TCE.
