The "indirect acquisition" includes that the terminal acquires information about cell coverage, such as several coordinate points, and the terminal can determine (e.g., outline) the coverage of the cell based on the acquired coordinates, so as to calculate the radius or diameter of the cell.

Similar to the first distance and the second distance, the third distance may also be a radius or a diameter of the third cell, or the third distance is a distance obtained by the terminal for cell reselection and related to the third cell, and is not described herein again to avoid repetition.

It should be noted that the aforementioned second cell and the third cell may be one or more.

(16) A second target threshold, the second target threshold being associated with a cell selection quality value, which may comprise a cell selection quality value of a serving cell and/or a cell selection quality value of a neighbor cell.

Wherein the cell selection quality value may be expressed as, but is not limited to, squal, which in one implementation is Squal = Q _qualmeas –(Q _qualmin +Q _{qualminoffset} )-Qoffset _temp ，Q _qualmeas RSRQ representing a measured cell; q _qualmin The minimum received signal required by the cell reselection is represented, and the minimum received signal can be used for controlling the difficulty degree of the cell reselection; q _{qualminoffset} A reception quality offset value representing the minimum received signal of the cell (note that the parameter Q may be used when the UE is camped on a VPLMN and cell selection is triggered by periodic search for a high priority PLMN _{qualminoffset} )；Qoffset _temp The offset representing the cell reselection may be set according to different cell reselection scenarios.

Alternatively, Q _qualmin 、Q _{qualminoffset} 、Qoffset _temp May be configured by the network side.

(17) A third target threshold value, the third target threshold value related to a cell selection reception level value, which may include a cell selection reception level value of a serving cell and/or a cell selection reception level value of a neighbor cell.

Wherein the cell selection reception level value may be, but is not limited to, represented as Srxlev, and in one implementation, srxlev = Q _rxlevmeas –(Q _rxlevmin +Q _{rxlevminoffset} )–P _compensation -Qoffset _temp Wherein, Q _rxlevmeas RSRP representative of the measured cell; q _rxlevmin Represents a cell lowest reception level; q _{rxlevminoffset} Indicating the cell lowest receive level offset value (note that the parameter Q may be used when the UE is camped on a VPLMN and cell selection is triggered by periodic searching for a high priority PLMN _{qualminoffset} )；P _compensation For punishing the UE which can not reach the maximum power of the cell, when the maximum allowed transmission power of the UE is less than or equal to the maximum transmission power supported by the capability of the UE, P _compensation ＝0；Qoffset _temp The offset representing the cell reselection may be set according to different cell reselection scenarios.

S320, the terminal performs cell reselection based on the cell reselection information and the terminal positioning information.

It is to be understood that, in addition to the implementation procedures described with reference to the method embodiment 200, as a possible implementation manner, the procedure of performing, by the terminal, cell reselection based on the cell reselection information and the terminal positioning information may include at least one of the following (21) to (24) according to different cell reselection scenarios.

(21) When the terminal acquires first system information, the residence time of the terminal in the serving cell exceeds a first predetermined value (such as 1 second), and a first condition is met, the terminal reselects a first target cell, the first target cell is a cell on a pilot frequency or a pilot system frequency, and the priority of the pilot frequency or the pilot system frequency corresponding to the first target cell is higher than the priority of the serving frequency of the serving cell. The first system information is related to the serving cell or the neighboring cell, and the first system information includes a quality threshold (ThreshServing, lowQ) corresponding to a cell selection quality value, where the quality threshold is used for the terminal to perform cell reselection, for example, to reselect a cell of a RAT or a frequency with a lower priority. In addition, the quality threshold value can also be used for the terminal to judge whether the cell reselection process is executed by using the cell selection quality value Squal or the cell selection reception level value Srxlev.

That is, for an inter-frequency (or inter-system frequency) higher in priority than a serving frequency of a serving cell (if the broadcasted first system information includes a quality threshold (LowQ)), and a cell on the frequency higher in priority than the current serving frequency or the inter-system frequency, i.e., a first target cell, should be reselected by the terminal since the terminal has camped on the current serving cell for more than 1 second and the first condition is satisfied.

In this case, of course, as one implementation, the first condition may include any one of the following (211) to (215).

(211) The cell selection quality value of the first target cell is greater than a first quality threshold during a first time interval.

Wherein a priority of a Radio Access Technology (RAT) or a priority of an E-UTRAN RAT corresponding to the first target cell is higher than a priority of a RAT corresponding to the serving cell, or a priority of an NR frequency or a priority of an EUTRAN frequency corresponding to the first target cell is higher than a priority of a serving frequency of the serving cell;

wherein the first quality threshold belongs to the second target threshold. The first time interval and the second, third and fourth time intervals mentioned for the subsequent implementation may be, but are not limited to, expressed as Treselection _RAT And the lengths of the first time interval, the second time interval, the third time interval and the fourth time interval can be appointed by a protocol and configured by a high layerOr network side device configuration is implemented, and lengths of the first time interval, the second time interval, the third time interval, and the fourth time interval may be the same or different, and particularly, lengths of the first time interval, the second time interval, the third time interval, and the fourth time interval may be 0, which is not limited herein. Specifically, if the first time interval, the second time interval, the third time interval, and the fourth time interval are 0, the network side may directly configure the first time interval, the second time interval, the third time interval, and the fourth time interval as 0, or the network side may not configure the first time interval, the second time interval, the third time interval, and the fourth time interval, and the terminal may be considered as 0.

(212) The first target cell satisfies a fifth condition during a first time interval.

Wherein the fifth condition is related to the target distance. In one implementation, the fifth condition includes at least one of (21201) - (21212) below. (21201) The ratio of the fourth distance to the first distance is greater than a second threshold.

Wherein the fourth distance is a distance d between the terminal and a reference position of a serving cell _serving The first distance is a distance R associated with the serving cell _serving Then the ratio between said fourth distance and the first distance may be d _serving /R _serving 。

(21202) A ratio between a fifth distance and the first distance is less than a third threshold, the fifth distance being a difference between the first distance and the fourth distance.

Wherein, let the fourth distance be d _serving The first distance is R _serving Then, the ratio between the fourth distance and the first distance may be (R) _serving -d _serving )/R _serving 。

(21204) A ratio of the sixth distance to the second distance is less than a fifth threshold.

The sixth distance is the distance d between the terminal and the reference position of the first target cell _neighbor The second distance being a distance associated with the first target cell, e.g. R _neighbor 。

(21205) A ratio between a seventh distance and the second distance is greater than a sixth threshold, wherein the seventh distance is a difference between the second distance and the sixth distance.

Assuming that the second distance is R _neighbor The sixth distance is d _neighbor Then the ratio of said seventh distance to said second distance is (R) _neighbor -d _neighbor )/R _neighbor 。

(21206) The fourth distance is greater than the sixth distance.

(21207) A ratio of the fourth distance to the first distance is greater than a ratio of the sixth distance to the second distance.

(21208) A ratio of the fifth distance to the first distance is less than a ratio of the seventh distance to the second distance.

(21209) The difference between the fourth distance and the sixth distance is greater than a first offset value (offset).

(21210) A first difference is greater than a second offset value, the first difference being a difference between a ratio of the fourth distance to the first distance and a ratio of a sixth distance to a second distance.

(21211) A second difference is less than a third offset value, the second difference being a difference between a ratio of the fifth distance to the first distance and a ratio of a seventh distance to a second distance. For example, assume that the first distance is R _serving The second distance is R _neighbor The fifth distance is (R) _serving -d _serving ) The seventh distance is (R) _neighbor -d _neighbor ) Then, the second difference may be represented as (R) _serving -d _serving )/R _serving -(R _neighbor -d _neighbo r)/R _neighbor 。

(21212) And the fourth distance is greater than the first threshold value, and the fourth distance is the distance between the terminal and the reference position of the serving cell. For example, assuming that the reference position of the serving cell is a cell center, the fourth cell is a distance between the current position of the terminal and the cell center.

Wherein the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, and the sixth threshold belong to the first target threshold.

Further, regarding the aforementioned calculation of the first distance, the second distance, the third distance, the fourth distance, the fifth distance, and the sixth distance, the reference position and the terminal position may be regarded as being located on one plane to calculate the shortest distance between the two points, or the reference position and the terminal position may be regarded as being located on one spherical surface to calculate the shortest distance between the two points.

For example, assume that the coordinate points acquired by the terminal are located on the same plane and are (x) respectively ₁ ,y ₁ )、(x ₂ ,y ₂ ) Then, the first distance calculated based on the specific algorithm and the coordinate point may be expressed as

For another example, assume that the coordinate points acquired by the terminal are located on the same plane and are (x) respectively ₁ ,y ₁ ,z ₁ )、(x ₂ ,y ₂ ,z ₂ ) Then, the first distance calculated based on the specific algorithm and the coordinate point may be expressed as

(2141) In an instance in which it is determined that the cell selection quality value of the first target cell is greater than the first quality threshold value within the first time interval, it is determined that the fifth condition is met or not met by the first target cell within a second time interval. That is, in this implementation, it is necessary to first determine whether the cell selection quality value of the first target cell is greater than the first quality threshold value in a first time interval, and then determine whether the first target cell satisfies the fifth condition in a second time interval.

(2142) Determining that the fifth condition is met or not met by the first target cell within a second time interval while determining that the cell selection quality value of the first target cell is greater than or not greater than the first quality threshold within the first time interval. That is, in this implementation, determining whether the cell selection quality value of the first target cell is greater than the first quality threshold and determining whether the first target cell satisfies the fifth condition may be performed simultaneously without distinguishing a precedence order.

(215) In a first time interval, the cell selection quality value of the first target cell is greater than the first quality threshold and the first target cell satisfies the fifth condition.

The second system information is related to the serving cell or the neighboring cell, and the second system information includes a quality threshold corresponding to a cell selection quality value, where the quality threshold is used for the terminal to perform cell reselection.

In other words, for an inter-frequency or inter-system frequency higher than the priority of the service frequency, if the broadcasted second system information does not include the quality threshold (threshServing LowQ) and has exceeded 1 second since the terminal camped on the current serving cell and the second condition is satisfied, the terminal should reselect to a cell on a frequency or inter-system frequency higher than the priority of the current service frequency, such as the second target cell.

(22204) And a sixth distance is smaller than a tenth threshold, wherein the sixth distance is a distance between the terminal and a reference position of a second target cell.

(22205) A ratio of the sixth distance to the second distance is less than an eleventh threshold.

(22206) A ratio between a seventh distance and the second distance is greater than a twelfth threshold, wherein the seventh distance is a difference between the second distance and the sixth distance.

(22207) The fourth distance is greater than the sixth distance.

(22208) A ratio of the fourth distance to the first distance is greater than a ratio of the sixth distance to the second distance.

(22209) A ratio of the fifth distance to the first distance is smaller than a ratio of the seventh distance to the second distance.

Wherein the seventh threshold, the eighth threshold, the ninth threshold, the tenth threshold, the eleventh threshold, the twelfth threshold belong to the first target threshold.

It should be noted that, although the sixth condition given in this implementation is the same as the implementation procedure of the fifth condition, the threshold values involved in the sixth condition may be different from and the same as the threshold values involved in the fifth condition. For example, the seventh threshold in the sixth condition may be the same as or different from the first threshold of the fifth condition, and in order to avoid repetition, the sixth condition is not described in detail in this embodiment.

(223) The second target cell satisfies a sixth condition, wherein the sixth condition is related to the target distance.

Wherein (223) differs from the aforementioned (222) in that: (223) The limitation of the third time interval is cancelled, that is, the terminal may directly determine whether the second target cell satisfies the sixth condition.

(224) The cell selection reception level value of the second target cell is greater than the first reception level threshold value for a third time interval, and the second target cell satisfies the sixth condition for a fourth time interval.

It may be understood that, in this embodiment, the second quality threshold may be a threshold corresponding to a serving cell, and the third quality threshold is a threshold corresponding to a neighboring cell.

(232) In a fifth time interval, the third target cell satisfies a seventh condition, wherein the seventh condition is related to the target distance.

For example, the fifteenth threshold in the seventh condition may be the same as or different from the first threshold of the fifth condition, and in order to avoid repetition, the sixth condition is not described again in this embodiment.

(233) The fourth target cell satisfies a seventh condition, wherein the seventh condition is related to the target distance.

(234) In a fifth time interval the cell selection quality value of the serving cell is smaller than the second quality threshold, the cell selection quality value of the third target cell is larger than the third quality threshold, and in a sixth time interval the third target cell fulfils the seventh condition.

That is, in this implementation, it is required to first determine that the cell selection quality value of the serving cell is smaller than the second quality threshold and the cell selection quality value of the third target cell is larger than the third quality threshold in a fifth time interval, and then the third target cell meets or does not meet the seventh condition in a sixth time interval.

It should be noted that, although the eighth condition given in this implementation is the same as the implementation procedure of the fifth condition, the threshold values involved in the sixth condition may be different from and the same as the threshold values involved in the fifth condition. For example, the nineteenth threshold in the eighth condition may be the same as or different from the first threshold in the fifth condition, and in order to avoid repetition, the eighth condition is not described in detail in this embodiment.

(243) The fourth target cell satisfies an eighth condition, wherein the eighth condition relates to the target distance.

It can be understood that, in this embodiment, for each of the aforementioned conditions, if the number of the adopted conditions is smaller, it means that the terminal is easier to reselect to a cell of another frequency, and if the number of the adopted conditions is larger, it means that the terminal is harder to reselect to a cell of another frequency.

In the above conditions, the judgment of which conditions are adopted or which conditions are not adopted for cell reselection can be configured by protocol agreement or a network side, and if the judgment is carried out by the protocol agreement, the cell reselection is always executed according to the conditions agreed by the protocol; if the network side is configured, the network side configures the conditions, and the terminal applies the conditions to perform cell reselection. For example, the network side device may indicate, through one or more bits, which conditions the terminal applies for cell reselection.

S330, when determining that a plurality of fifth target cells are located based on the cell reselection information and the terminal positioning information, the terminal reselects a sixth target cell, where the sixth target cell is a cell with a highest RAT priority or a highest frequency priority among the plurality of fifth target cells.

That is, if multiple cells of different priorities meet the cell reselection criteria, cell reselection to a higher priority RAT/frequency should take precedence over a lower priority RAT/frequency.

It is to be understood that, for the first target cell, the second target cell, the third target cell, and the fourth target cell described in the foregoing S220, when there are a plurality of cells satisfying the first condition, the second condition, the third condition, or the fourth condition, the first target cell, the second target cell, the third target cell, and the fourth target cell may be understood as the sixth target cell, that is, the first target cell, the second target cell, the third target cell, and the fourth target cell are the cells with the highest RAT priority or frequency priority among the plurality of cells satisfying the first condition, the second condition, the third condition, or the fourth condition.

In one implementation, in the case that there are a plurality of the fifth target cells and RAT priorities or frequency priorities of the plurality of fifth target cells are the same, the terminal performs cell reselection among the plurality of fifth target cells based on a first criterion; the first criterion is a same-frequency and equal-priority pilot frequency cell reselection criterion.

That is, if a plurality of cells satisfy the above first condition, or second condition, third condition, or fourth condition, etc., and the highest priority frequency is an NR frequency, the terminal should reselect the highest ranked cell satisfying a first criterion, which is an intra-frequency and equal priority inter-frequency cell reselection criterion.
