Detailed Description

In a mobile communication system such as LTE or NR, for example, in a Handover scenario where a mobile device is handed over (Handover or Cell Switching) from one Cell to another, the mobile device may make at least one measurement related to the Handover and generate one or more MRs of the type "Handover MRs". In such a handover MR, information such as, but not limited to, MR type, identification of the mobile device, timestamp, Reference Signal Receiving Power (RSRP) of the current serving cell (e.g., the cell in which the mobile device is located), and RSRP of one or more (e.g., all) detectable non-serving cells (e.g., neighboring cells) may be included, for example.

In addition, the mobile device may also perform measurements under any other suitable circumstances and generate a corresponding type of MR. In this document, to distinguish from "switched MRs," these MRs are collectively referred to as "non-switched MRs" or "conventional MRs," sometimes also referred to as "other MRs. Similarly to the handover MR, in the non-handover MR, for example, but not limited thereto, information such as MR type, identification of the mobile device, timestamp, RSRP of the current serving cell, RSRP of one or more (e.g., all) detectable non-serving cells (e.g., neighbor cells), etc. may also be included. For example, there may be non-handover MRs that may be used to indicate that the mobile device actually occurred/completed a handover from one cell to another.

In MR-based mobile device location/movement trajectory analysis and the like, for example, on the side of a location server of an operator (which may be configured in a support network, for example), an MR associated with a specified one or more mobile devices may be received from a base station periodically or according to a task instruction. For example, an MR record file may be received from a base station, in which one or more MRs associated with a specified one or more mobile devices and within a specified time period may be included. The obtained data/information in the MR may then be matched (e.g., similarity matched, etc.) with data in a database (e.g., a radio frequency fingerprint database) for processing of mobile device location/motion trajectory analysis, etc., to determine the location and/or motion trajectory of the mobile device, for example.

However, different mobile devices may have different hardware designs, for example, different chip sets, different antenna designs and configurations, etc., so that data in the MR from different mobile devices may not match or exactly match data in the database, thereby possibly affecting the accuracy of processing such as MR-based mobile device positioning/motion trajectory analysis.

Fig. 1 illustrates an example method 100 of determining information for mobile device positioning in an embodiment of the present disclosure. For example, the example method 100 may be performed in an apparatus such as a location server of a network operator.

As shown in fig. 1, the example method 100 may include:

step 110, for at least one handover of a first mobile device from a first cell to a second cell, determining at least one handover MR of the first mobile device within the first cell (e.g., with the first cell as a serving cell) and at least one non-handover MR of the first mobile device within the second cell (e.g., with the second cell as a serving cell) (i.e., MRs of a type different from the "handover MR", which may sometimes also be referred to as "conventional MRs");

step 120 of determining a first reference quantity related to at least one handover of the first mobile device from the first cell to the second cell, based on at least one first RSRP for the second cell included in the aforementioned at least one handover MR; and

step 130, determining information for positioning the mobile device according to a second reference quantity related to at least one handover of a plurality of mobile devices from the first cell to the second cell, the first reference quantity and at least one second RSRP in the at least one non-handover MR.

In the example method 100, references relating to a specified handover scenario of a mobile device, including a first reference relating to the specified handover scenario of a specified mobile device and a second reference relating to the specified handover scenario of a plurality of mobile devices, are determined from information in a handover MR, and information for mobile device positioning is then determined from the determined references and information in a non-handover MR. Since different mobile devices may be located in the same or similar locations under the same handover scenario (i.e., the serving cells before handover are the same and the serving cells after handover are the same), and the RSRPs of the measured serving and target cells may have similar characteristics, e.g., RSRPs measured by different mobile devices may exhibit cluster characteristics, different mobile devices may have the same or similar "maximum probability peak difference of RSRPs of serving and non-serving cells", etc., using the reference obtained based on the information in the handover MR, data differences due to, e.g., heterogeneity of mobile devices can be eliminated or mitigated, thereby enabling reliable data to be provided that can be used for mobile device positioning.

More details of the example method 100 are described below.

In step 110 of the example method 100, at least one handover MR of a serving cell from a first cell and at least one non-handover MR of a serving cell from a second cell associated with at least one handover of a first mobile device from the first cell to the second cell may be determined.

For example, a handover MR sequence associated with the first mobile device may be determined from the time stamp information in the MRs, and then at least one handover of the first mobile device from the first cell to the second cell may be determined from at least one pair of adjacent handover MRs in the handover MR sequence.

As shown in fig. 2, the handover MRs associated with the first mobile device UE1 may be ordered chronologically to obtain a handover MR sequence 200 associated with the first mobile device UE 1.

In the example of fig. 2, the switching MRs in the switching MR sequence 200 are shown from top to bottom in chronological order, where the switching MR corresponding to the timestamp t _0 precedes the switching MR corresponding to the timestamp t _1, the switching MR corresponding to the timestamp t _1 precedes the switching MR corresponding to the timestamp t _2, the switching MR corresponding to the timestamp t _2 precedes the switching MR corresponding to the timestamp t _3, and so on. In fig. 2, for example, there is no further handover MR related to the first device UE1 between the handover MR corresponding to the timestamp t _0 and the handover MR corresponding to the timestamp t _1, between the handover MR corresponding to the timestamp t _2 and the handover MR corresponding to the timestamp t _3, between the handover MR corresponding to the timestamp t _4 and the handover MR corresponding to the timestamp t _5, between the handover MR corresponding to the timestamp t _6 and the handover MR corresponding to the timestamp t _ 7; further one or more handover MRs related to the first device UE1 may be included between the handover MR corresponding to timestamp t _1 and the handover MR corresponding to timestamp t _2, between the handover MR corresponding to timestamp t _3 and the handover MR corresponding to timestamp t _4, between the handover MR corresponding to timestamp t _5 and the handover MR corresponding to timestamp t _6, after the handover MR corresponding to timestamp t _7, as indicated by the vertical ellipses in fig. 2.

In addition, in the example of fig. 2, the timestamps t _0 to t _7 are used to schematically show the precedence relationship between the handover MRs, but two neighboring handover MRs in the handover MR sequence 200 (e.g., the handover MR corresponding to the timestamp t _0 and the handover MR corresponding to the timestamp t _ 1) may not be two neighboring MRs in a complete MR sequence associated with the first mobile device UE1 that is ordered chronologically. For example, one or more non-handover MRs (not shown in fig. 2) associated with the first mobile device UE1 may also be included between t _0 and t _1 in a chronologically ordered complete MR sequence associated with the first mobile device UE 1. In other words, for any two neighboring handover MRs in the example of fig. 2, the two handover MRs may be neighboring in a complete MR sequence associated with the first mobile device UE1 that is ordered chronologically, or one or more non-handover MRs may be included between the two handover MRs.

In addition, as shown in fig. 2, in each handover MR in the handover MR sequence 200, in addition to the timestamp information, information such as a mobile device identification (e.g., UE1 in each MR in the example of fig. 2), an MR type (e.g., in the example of fig. 2, a handover MR is indicated by "S"), an identification of a current serving Cell (e.g., in the example of fig. 2, Cell _ a in each MR corresponding to t _0 to t _2, t _5 to t _6, Cell _ B in each MR corresponding to t _3 to t _4, t _ 7), an RSRP of a current serving Cell (e.g., in the example of fig. 2, RSRP _ a in each MR corresponding to t _0 to t _2, t _5 to t _6, RSRP _ a in each MR corresponding to t _3 to t _4, t _ 7), an identification of a currently detectable non-serving Cell (e.g., an adjacent Cell (e.g., in the example of fig. 2, Cell _ B, Cell _ C, Cell _ D, Cell _ E in MR corresponding to t _0 to t _2, t _5 to t _6, Cell _ A, Cell _ C, Cell _ E in MR corresponding to t _3 to t _4, t _7, etc.), RSRP of currently detectable non-serving Cell (e.g., neighboring Cell) (e.g., RSRP _ B, RSRP _ C in MR corresponding to t _0 to t _2, t _5 to t _6, RSRP _ a in MR corresponding to time stamps t _3 to t _4, t _7, etc.) and other information.

It should be understood that in the example of fig. 2, RSRP _ a in each handover MR is used to schematically indicate that this field corresponds to the value of RSRP for Cell _ a, and the values of RSRP _ a in each handover MR may be the same or different. Similarly, the values of RSRP _ B or RSRP _ C in each handover MR may be the same or different. In addition, the form and content of each switching MR in fig. 2 are examples, and the form and content of an actual MR may be different therefrom, and the present disclosure is not limited to the form and content of an MR.

A cell handover of the first mobile device UE1 may then be determined, for example, from a different adjacent pair of handover MRs serving the cells. For example, in the example of fig. 2, it may be determined that the first mobile device UE1 has occurred once a handover 210 from Cell _ a to Cell _ B during a time period corresponding to t _2 to t _3, once a handover 220 from Cell _ B to Cell _ a during a time period corresponding to t _4 to t _5, and once again a handover 230 from Cell _ a to Cell _ B during a time period corresponding to t _5 to t _ 6. Accordingly, a handover scenario from Cell _ a to Cell _ B may include at

least handovers

210 and 230, and a handover scenario from Cell _ B to Cell _ a may include at least handover 220.

For example, for a handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B, in step 110 of the example method 100, the determined at least one first handover MR may comprise, for example, handover MRs serving Cell _ a before handover 210 occurs (e.g., within t _0 to t _ 3), handover MRs serving Cell a after handover 220 occurs and before subsequent handover 230 occurs (e.g., within t _5 to t _ 7), and the determined at least one non-handover MR may comprise, for example, handover MRs serving Cell B after handover 210 occurs and before subsequent handover 220 occurs (e.g., within t _3 to t _ 5), and another Cell handover occurring after handover 230 occurs (e.g., after t _ 7) and immediately after handover 230 occurs (not shown in fig. 2; if there is no further Cell handover, may be to the end of the sequence) each non-handover MR with Cell B as the serving Cell before it occurs. For example, for a handover scenario from Cell _ B to Cell _ a, in step 110 of example method 100, the determined at least one first handover MR may comprise respective handover MRs with Cell _ B as a serving Cell, e.g., after handover 210 occurs and before subsequent handover 220 occurs (e.g., within t _3 to t _ 5), and the determined at least one non-handover MRs may comprise respective non-handover MRs with Cell _ a as a serving Cell, e.g., after handover 220 occurs and before subsequent handover 230 occurs (e.g., within t _5 to t _ 7).

In addition, as shown in fig. 3, the MRs associated with the first mobile device UE1 may also be sorted by time, for example, according to the timestamp information in the MRs, thereby obtaining an MR sequence 300 associated with the first mobile device UE1, which may include handover MRs associated with the first mobile device and at least one non-handover MR.

The meaning and representation of the elements in the example of fig. 3 (e.g., the form of the respective example MR) is similar to that in the example of fig. 2. For example, in fig. 3, similarly to the case in fig. 2, for each MR, "S" is used to represent a switching MR, and correspondingly, "N" is used to represent a non-switching MR. For example, in fig. 3, the chronological order between MRs is represented using t _0 to t _18, similarly to the case in fig. 2. For example, in fig. 3, similarly to the case in fig. 2, there is no additional switching MR related to the first device UE1 between the switching MR corresponding to the time stamp t _0 and the switching MR corresponding to the time stamp t _2, between the switching MR corresponding to the time stamp t _4 and the switching MR corresponding to the time stamp t _7, between the switching MR corresponding to the time stamp t _11 and the switching MR corresponding to the time stamp t _14, between the switching MR corresponding to the time stamp t _15 and the switching MR corresponding to the time stamp t _ 19. If there is no additional switching MR between the two switching MRs, the two switching MRs may be referred to as "adjacent two switching MRs" similarly to the case in the example of fig. 2. For example, in fig. 3, similar to the case in fig. 2, between the non-handover MR corresponding to the timestamp t _3 and the handover MR corresponding to the timestamp t _4, between the non-handover MR corresponding to the timestamp t _9 and the non-handover MR corresponding to the timestamp t _10, between the handover MR corresponding to the timestamp t _14 and the handover MR corresponding to the timestamp t _15, after the handover MR corresponding to the timestamp t _19, further one or more handover MRs related to the first device UE1 may also be included, and further one or more non-handover MRs related to the first device UE1 may also be included, indicated by vertical ellipses in fig. 3. Further details of the same or similar parts are not repeated.

Then, at least one cell handover of the first mobile equipment UE1 may be determined, e.g. from two neighbouring handover MRs with different serving cells. For example, in the example of fig. 3, it may be determined that the first mobile device UE1 has occurred once a handover 310 from Cell _ a to Cell _ B during a time period corresponding to t _4 to t _7, has occurred once a handover 320 from Cell _ B to Cell _ a during a time period corresponding to t _11 to t _14, and has occurred once again 330 from Cell _ a to Cell _ B during a time period corresponding to t _15 to t _ 19. Accordingly, a handover scenario for the first mobile device UE1 from Cell _ a to Cell _ B may include at

least handovers

310 and 330, for example.

Then, for example, for a handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B, in step 110 of the example method 100, the determined at least one first handover MR may comprise each handover MR of the serving Cell with Cell _ a before handover 310 occurs (e.g., t _0 to t _4), each handover MR of the serving Cell with Cell _ a after handover 320 occurs and before subsequent handover 330 occurs (e.g., within t _14 to t _ 15), and the determined at least one non-handover MR may comprise each non-handover MR of the serving Cell with Cell _ B after handover 310 occurs and before subsequent handover 320 occurs (e.g., t _4 to t _14), and another Cell handover occurring after handover 330 occurs (e.g., after t _ 15) and immediately after handover 330 (not shown in figure 3; if there is no further Cell handover, may be to the end of the sequence) each non-handover MR with Cell B as the serving Cell before it occurs.

As shown in fig. 4, in the MR sequence 300, if the serving cells of two adjacent MRs (which may be two non-handover MRs, two handover MRs, or one handover MR and one non-handover MR) are different, it can be determined that one cell handover has occurred. For example, the serving Cell of the non-handover MR corresponding to the time stamp t _6 is Cell _ a, the serving Cell of the subsequent non-handover MR corresponding to the time stamp t _7 is Cell _ B, the serving cells in the two MRs are different, and thus it can be determined that, for example, at t _6, a handover 310 from Cell _ a to Cell _ B has occurred; similarly, it may be determined that a handover from Cell _ B to Cell _ a occurs once at t _13 from two MRs corresponding to t _12 and t _13 320, that a handover from Cell _ a to Cell _ B occurs once at t _16 from two MRs corresponding to t _15 and t _16, and so on. Thus, it may also be determined that the handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B may include at

least handovers

310 and 330, and that the handover scenario of the first mobile device UE1 from Cell _ B to Cell _ a may include at least handover 320.

Then, for example, for a handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B, in step 110 of the example method 100, a handover MR with Cell _ a as a serving Cell may be looked up in MRs t _0 to t _5, and a handover MR with Cell _ a as a serving Cell may be looked up in MRs t _13 to t _16, and so on, for example, to determine at least one first handover MR relevant to the handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B.

In addition, for example, a non-handover MR with Cell _ B as a serving Cell may also be found among MRs from t _6 to t _12, and a non-handover MR with Cell _ B as a serving Cell may be found among MRs from t _17 to an MR indicating another Cell different from Cell _ B immediately after the handover 330 (not shown in fig. 3; if not, may be to the end of the sequence), and so on, to determine at least one non-handover MR related to a handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B.

In addition, in step 110, at least one first handover MR and at least one non-handover MR relating to a handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B may also be determined by combining the methods in the examples of fig. 2 and 3. For example, at least one first handover MR of a serving Cell _ a related to a handover scenario of the first mobile device UE1 from Cell _ a to Cell _ B may be determined from the handover MR sequence 200; then, at least one non-handover MR of the serving Cell from Cell _ a to Cell _ B related to the handover scenario of the first mobile device UE1 may be determined in the MR sequence 300 from the non-handover MR indicating the occurrence of a Cell handover.

After determining at least one first handover MR and at least one non-handover MR related to a handover scenario of the first mobile device UE1 from the first Cell _ a to the second Cell _ B through step 110, the example method 100 may continue to step 120 and determine a first reference related to a handover scenario of the first mobile device UE1 from the first Cell _ a to the second Cell _ B according to at least one first RSRP related to the second Cell _ B included in the at least one first handover MR determined in step 110.

Still taking the case of the MR sequence 300 in fig. 3 or fig. 4 as an example, as shown in fig. 5, in step 120 the selected at least one first RSRP may for example comprise RSRP _

bs

510, 520, 530 and 540. Additionally, the selected at least one first RSRP may also include one or more of RSRP _

bs

510, 520, 530, and 540. For example, one of 510 and 520 (e.g., 520) associated with switch 310 and one of 530 and 540 (e.g., 540) associated with switch 330 may be selected; for example, one of 510 and 520 associated with

switch

310 and 530 and 540 associated with switch 330 may also be selected; and so on.

For example, in step 120, the first reference amount may be determined according to the selected statistical value of the at least one second RSRP. For example, a first reference quantity related to handover of the first mobile device UE1 from the first Cell _ a to the second Cell _ B may be determined from an average (e.g., an arithmetic average or a weighted average, etc.) of at least one first RSRP including RSRP _ B510, 520, 530, and 540. For example, the first reference may also be determined from any other suitable statistics (e.g., median, high-frequency-of-occurrence values, etc.) for at least one first RSRP including RSRP _

bs

510, 520, 530, and 540. For example, a first statistical quantity (e.g., an arithmetic mean) associated with 510 and 520 associated with the switch 310 may also be determined, and a second statistical quantity (e.g., a weighted mean) associated with 530 and 540 associated with the switch 330 may be determined, and then the first reference quantity may be determined based on the first statistical quantity and the second statistical quantity (e.g., an arithmetic mean or a weighted average of the two).

The example method 100 may then continue to step 130 and determine information for mobile device positioning based on the first reference determined in step 120, a second reference associated with a handover scenario (or at least one handover associated with the handover scenario) of the plurality of mobile devices from the first Cell _ a to the second Cell _ B, and at least one second RSRP included in the at least one non-handover MR determined in step 110.

Still taking the case of the MR sequence 300 in fig. 3 to 5 as an example, as shown in fig. 6, the at least one second RSRP used in step 130 may comprise an RSRP marked with a bold wireframe. For example, the at least one second RSRP used in step 130 may include all RSRPs of all non-handover MRs determined in step 110 (including RSRPs of serving cells in each non-handover MR and RSRPs of non-serving cells in each non-handover MR), and may also include one or more RSRPs of one or more non-handover MRs determined in step 110.

In one embodiment, the plurality of mobile devices related to the second reference in step 130 may comprise the first mobile device UE1 and one or more second mobile devices, and the second reference may depend on the at least one first RSRP used in step 120 and on the at least one third RSRP for the second Cell _ B, wherein the third RSRP may be comprised in at least one second handover MR related to at least one handover of the second mobile device from the first Cell _ a to the second Cell _ B and within the first Cell _ a.

For example, as shown in fig. 7, in addition to the handover MR sequence 200 related to the first mobile device UE1, for example, the positioning server may obtain, from the base station, MRs related to one or more second mobile devices UE2, UE3, and the like, and may obtain, using a method similar to that for obtaining the handover MR sequence 200, a handover MR sequence 710 related to the second mobile device UE2 (in which the precedence order of the handover MR switching timestamps t _0 'to t _ 7' is ordered), and a handover MR sequence 720 related to the second mobile device UE3 (in which the precedence order of the handover MR switching timestamps t _0 "to t _ 7" is ordered), and the like. For example, from the handover MR sequence 710, at least one

handover

711 and 713 of the second mobile device UE2 from Cell _ a to Cell _ B and a handover 712 of the second mobile device UE2 from Cell _ B to Cell _ B may be determined; from the handover MR sequence 720, a handover 721 of the second mobile device UE3 from Cell _ B to Cell _ D, a handover 722 of the second mobile device UE3 from Cell _ D to Cell _ a, a handover 723 of the second mobile device UE3 from Cell _ a to Cell _ B may be determined.

Then, for example, for a handover scenario from the first Cell _ a to the second Cell _ B, at least one handover MR with Cell _ a as a serving Cell, e.g., a handover MR from t _0 'to t _ 2' and a handover MR from t _5 'to t _ 6', may be determined from the handover MR sequence 710 in the same processing manner as the processing for the handover MR sequence 200 in step 110, in relation to at least one

handover

711 and 713 of the second mobile device UE2 from Cell _ a to Cell _ B. Likewise, at least one handover MR of the serving Cell _ a, e.g., t _5 "to t _ 6", may be determined from the handover MR sequence 720 in relation to the at least one handover 723 of the second mobile device UE3 from Cell _ a to Cell _ B.

Then, one or more third RSRPs for Cell _ B may be determined in the one or more handover MRs serving Cell determined from the

handover MR sequences

710 and 720, e.g., may include one or more of 714, 715, 716, 717, 724, and 725 shown in fig. 7.

In further examples, the processing approaches in the examples of fig. 3-5 may also be employed to determine a different handover scenario and corresponding one or more third RSRPs than the second mobile device UE2 or UE 3.

The second reference may then be determined from one or more of the

third RSRPs

714, 715, 716, 717, 724 and 725 and the statistical values (e.g. average values, median values, numerical values with high frequency of occurrence, etc.) of the at least one first RSRP determined in step 120 (e.g. one or more of 510, 520, 530 and 540 in the example of fig. 5).

Then, in step 130, for example, a deviation of the first reference quantity from the second reference quantity may be determined and the aforementioned at least one second RSRP 610, 615, 620, 625, 630, 635, 640, 645, 650, and 655 may be adjusted using the determined deviation, thereby obtaining at least one adjusted RSRP. For example, such adjustments may include, but are not limited to, adding the determined bias, subtracting the determined bias, adding the product of the bias and another specified coefficient, etc., on the basis of the second RSRP.

In this embodiment, the information obtained by the example method 100 for mobile device positioning may comprise the second reference amount and the at least one adjusted RSRP. Based on such information, a database (e.g., a radio frequency fingerprint database) that may be used for mobile device location/movement trajectory tracking may be constructed in any suitable manner, for example.

In further embodiments, the plurality of mobile devices considered in determining the second reference quantity related to the handover scenario from the first Cell _ a to the second Cell _ B may also not comprise the first mobile device UE1, or may comprise the first mobile device UE1, but consider a further handover MR sequence or MR sequence related to the first mobile device UE1 but different from the handover MR sequence 200 or MR sequence 300 in the previous examples.

Accordingly, in this embodiment, the second reference quantity related to the handover scenario from the first Cell _ a to the second Cell _ B may depend on at least one third reference signal received power with respect to the second Cell _ B, such at least one third reference signal received power may be included in at least one second handover measurement report related to at least one handover of a plurality of mobile devices (which may or may not include the first mobile device UE1, the first mobile device UE1) from the first Cell a to the second Cell _ B and which are within the first Cell a (with Cell _ a as the serving Cell). For example, such a second reference quantity may depend on statistical values (e.g., average value, median, value with high frequency of occurrence, etc.) with respect to the third reference signal received power.

Then, in step 130, for example, a deviation of a first reference quantity related to the first mobile device UE1 from a second reference quantity related to a plurality of mobile devices (which may or may not include the first mobile device UE1 and the first mobile device UE1) may be determined, and the aforementioned at least one second RSRP is adjusted using the determined deviation, thereby obtaining at least one adjusted RSRP.

In this embodiment, the information obtained by the example method 100 for mobile device positioning may comprise at least one adjusted RSRP. Based on this information, for example, any suitable method may be employed for radio frequency fingerprint matching, thereby enabling location/movement trajectory analysis, etc. for the first mobile device UE 1.

Fig. 8-10 further illustrate examples of some implementations of the example method 100.

In the example process 800 of fig. 8, the example method 100 may be performed for an MR associated with each of a plurality of mobile devices UE _1, UE _2, … …, UE _ n (n is any natural number) for a handover scenario from Cell _ a to Cell _ B.

For example, the example method 100 may be performed based on the MR sequence 810 related to the mobile device UE _1, thereby obtaining a first reference quantity 811 related to at least one handover of the mobile device UE _1 from Cell _ a to Cell _ B and at least one second RSRP 812 (e.g., all RSRPs in each non-handover MR that may be determined for UE _1 in step 110 of the example method 100 may be included); the example method 100 may be performed based on the MR sequence 820 related to the mobile device UE _2, thereby obtaining a first reference 821 related to at least one handover of the mobile device UE _2 from Cell _ a to Cell _ B and at least one second RSRP 822 (e.g., all RSRPs in each non-handover MR that may be determined for UE _2 in step 110 of the example method 100); similarly, the example method 100 may be performed based on the MR sequence 830 related to the mobile device UE _ n to obtain the first reference quantity 831 and the at least one second RSRP 832 related to at least one handover of the mobile device UE _ n from the Cell _ a to the Cell _ B (e.g., all RSRPs in each non-handover MR that may be determined for UE _ n in step 110 of the example method 100 may be included).

Additionally, a second reference 840 relating to at least one handover of a plurality of mobile devices UE _1, UE _2, … …, UE _ n from Cell _ a to Cell _ B may be determined based on the MR sequence 810 relating to mobile device UE _1, the MR sequences 820, … … relating to mobile device UE _2, the MR sequence 830 relating to mobile device UE _ n, and so on.

Then, a bias 813 associated with the mobile device UE _1 may be determined from the first reference 811 associated with the mobile device UE _1 and the second reference 840 associated with the plurality of mobile devices, and at least one adjusted second RSRP 814 may be determined from the bias 813 and the at least one second RSRP 812 associated with the mobile device UE _ 1. Similarly, a deviation 823 associated with the first device UE _2 may be determined from a first reference 821 associated with the mobile device UE _2 and a second reference 840 associated with the plurality of mobile devices, and at least one adjusted second RSRP 824 may be determined from the deviation 823 and at least one second RSRP 822 associated with the mobile device UE _ 2. By analogy, a deviation 833 related to the first device UE _ n may be determined from the first reference 831 related to the mobile device UE _ n and the second reference 840 related to the plurality of mobile devices, and at least one adjusted second RSRP 834 may be determined from the deviation 833 and the at least one second RSRP 832 related to the mobile device UE _ n.

Then, as shown in fig. 8, a second reference quantity 840 related to at least one handover of a plurality of mobile devices UE _1, UE _2, … …, UE _ n from Cell _ a to Cell _ B, at least one adjusted second RSRP 814 related to at least one handover of mobile device UE _1 from Cell _ a to Cell _ B, at least one adjusted second RSRP 824, … … related to at least one handover of mobile device UE _2 from Cell _ a to Cell _ B, at least one adjusted second RSRP 834 related to at least one handover of mobile device UE _ n from Cell _ a to Cell _ B may be output as part of information for mobile device positioning related to a handover scenario from Cell _ a to Cell _ B. A database (e.g., a radio frequency fingerprint database) may then be constructed, for example, based on such information. For example, a second reference quantity relating to a plurality of mobile devices and information determined from adjusted RSRP records for the respective mobile devices (e.g. radio frequency fingerprint information) may be stored in a database.

In the example process 900 of fig. 9, for a handover scenario from Cell _ a to Cell _ B, for example, the example method 100 may be performed based on the MR sequence 910 related to the mobile device UE _1, thereby obtaining a first reference quantity 911 and at least one second RSRP 912 related to at least one handover of the mobile device UE _1 from Cell _ a to Cell _ B (e.g., all RSRPs in each non-handover MR determined for UE _1 in step 110 of the example method 100 may be included).

In addition, a second reference quantity 940 relating to at least one handover of a plurality of mobile devices UE _2, … …, UE _ n from Cell _ a to Cell _ B may be determined based on MR sequences 920, … … relating to mobile device UE _2, MR sequences 930 relating to mobile device UE _ n (n is any natural number), and so on.

Then, a second reference quantity 940 relating to the plurality of mobile devices UE _2, … …, UE _ n may be determined. For example, such a second reference quantity 940 may be read directly from a constructed database or may be determined for a plurality of mobile devices UE _2 to UE _ n applying the example method 100.

Then, a deviation 913 associated with the mobile device UE _1 may be determined based on the first reference 911 associated with the mobile device UE _1 and the second reference 940 associated with the plurality of mobile devices UE _2, … …, UE _ n, and at least one adjusted second RSRP 914 may be determined based on the deviation 913 and the at least one second RSRP 912 associated with the mobile device UE _ 1.

Then, for example, the at least one adjusted second RSRP 914 may be used to match (e.g., similarity match, etc.) data in a constructed database (e.g., a radio frequency fingerprint database) to perform MR-based positioning or movement trajectory analysis, etc. for the mobile device UE _ 1. For example, the data in the constructed database may be information, such as radio frequency fingerprint information, constructed based on data/information obtained by applying the example method 100 in advance for a plurality of mobile devices (e.g., fig. 8).

In the example process 1000 of fig. 10, for a handover scenario from Cell _ a to Cell _ B, the example method 100 may be performed, for example, based on the MR sequence 1010 related to the mobile device UE _1, thereby obtaining a first reference 1011 and at least one second RSRP 1012 related to at least one handover of the mobile device UE _1 from Cell _ a to Cell _ B (e.g., all RSRPs in each non-handover MR that may be determined for UE _1 in step 110 of the example method 100 may be included).

In addition, a second reference 1040 related to at least one handover of a plurality of mobile devices UE _1, … …, UE _ n from Cell _ a to Cell _ B may be determined based on MR sequences 1020 (which may be different from 1010) related to mobile device UE _1, … …, MR sequences 1030 related to mobile device UE _ n (n is any natural number), and so on.

Then, a second reference quantity 940 relating to the plurality of mobile devices UE _1, … …, UE _ n may be determined. For example, such a second reference quantity 940 may be read directly from a constructed database or may be determined for a plurality of mobile devices UE _1 to UE _ n applying the example method 100.

Then, a deviation 1013 associated with the mobile device UE _1 may be determined from the first reference 1011 associated with the mobile device UE _1 and the second reference 1040 associated with the plurality of mobile devices UE _1, … …, UE _ n, and at least one adjusted second RSRP 1014 may be determined from the deviation 1013 and the at least one second RSRP 1012 associated with the mobile device UE _ 1.

Then, for example, the at least one adjusted second RSRP 1014 may be used to match (e.g., similarity match, etc.) data in a constructed database (e.g., a radio frequency fingerprint database) to perform MR-based positioning or movement trajectory analysis, etc. for the mobile device UE _ 1. For example, the data in the constructed database may be information, such as radio frequency fingerprint information, constructed based on data/information obtained by applying the example method 100 in advance for a plurality of mobile devices (e.g., fig. 8).
