However, in an unlicensed frequency band, since multiple operators may deploy networks in the same frequency band, when a terminal (User Equipment, UE) performs cell reselection in the unlicensed frequency band, it may need to perform multiple selections to select a cell suitable for the terminal, so that the efficiency of the terminal in performing cell reselection is reduced.
Therefore, the problem of low efficiency exists in the cell reselection process of the terminal at present.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic network diagram applicable to the embodiment of the present invention, and as shown in fig. 1, the network diagram includes a terminal 11 and a network side Device 12, where the terminal 11 may be a terminal side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that a specific type of the user terminal 11 is not limited in the embodiment of the present invention. The network side device 12 may be a macro station, an LTE eNB, a 5G NR gbb, or the like; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, or the network side device 12 may be an Access Point (AP); the network-side device 12 may also be a network node formed by a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) managed and controlled by the CU. It should be noted that the specific type of the network-side device 12 is not limited in the embodiment of the present invention.
Referring to fig. 2, fig. 2 is a flowchart of a method for determining a cell according to an embodiment of the present invention, which is applied to a terminal, and the terminal operates in an unlicensed frequency band, as shown in fig. 2, the method for determining a cell includes the following steps:
step 101, obtaining white list information from broadcast information received by a current cell.
And 102, determining a cell for cell reselection based on the white list information.
Here, the terminal may determine a cell for cell reselection based on the white list information acquired from the broadcast information received by the current cell, so that the terminal may more quickly determine a suitable cell for cell reselection, thereby improving the efficiency of cell reselection of the terminal.
In step 101, when the current cell of the terminal, that is, the cell where the terminal currently resides, sends broadcast information, and the broadcast information carries the white list information, the terminal may receive the broadcast information and obtain the white list information from the broadcast information.
The white list information may be any information for the terminal to determine the cell for cell reselection, for example, the white list information may be a white list (i.e., a cell list) including at least one cell, and then in step 102, the terminal may select a cell from the at least one cell as the cell for cell reselection, and so on.
It should be noted that, when the terminal operates in an unlicensed frequency band, a current cell may support multiple Public Land Mobile Networks (PLMNs), and in this case, the terminal determines a cell for cell reselection based on the white list information, and may erroneously determine a cell that only supports PLMNs other than its own PLMN as a cell for cell reselection, thereby affecting the terminal to perform cell reselection.
For example, in a case where a Radio Access Network (RAN) is shared, one cell may provide services for terminals of multiple operators. At this time, cell a broadcasts the IDs of multiple PLMNs (i.e., PLMN ID list), that is, cell a supports multiple PLMNs. In this case, since operator a (the operator that deploys cell a) may not know which cells operator B (the operator that rents cell a) deploys in the vicinity of cell a, the white list of operator B's cells in the broadcast information of cell a may not be included in the white list information. Therefore, when the terminal of the operator B performs cell selection based on the white list, it can reselect only the cell of the operator a, but not the cell of the operator B.
In some embodiments, the current cell supports M public land mobile networks, PLMNs, where M is a positive integer greater than 1;
the white list information includes at least one white list and information indicating a correspondence between the white list and the PLMN.
In this case, in the case that the terminal determines the cell for cell reselection, the terminal may determine the cell for cell reselection only based on the white list having a correspondence relationship with its own PLMN, that is, the step 102 may include: and determining a cell for cell reselection based on a white list corresponding to a first PLMN, wherein the first PLMN is the PLMN of the terminal, so that the terminal is prevented from determining a cell supporting only PLMNs except the PLMN as the cell for cell reselection, and the cell reselection efficiency is further improved.
The first PLMN may be one of a PLMN selected by the terminal, a registered PLMN, and an equivalent PLMN.
In addition, the white list referred to in this embodiment is actually a cell list including at least one cell.
It should be noted that the information indicating the correspondence between the white list and the PLMN may be any information capable of indicating the correspondence between the white list and the PLMN, and specifically, the information indicating the correspondence between the white list and the PLMN may include: the corresponding relation between each white list and the PLMN in the at least one white list, and the number of the PLMNs corresponding to any white list is less than M; or, the first indication information of at least one PLMN is used for indicating whether the PLMN has a corresponding white list, so that the setting modes of the white list information are diversified.
The information indicating the correspondence between the white lists and the PLMNs includes a correspondence between each white list and a PLMN in the at least one white list, and the number of PLMNs corresponding to any white list is less than M, which may be understood as: each white list in the at least one white list has a corresponding relationship with one or more PLMNs, and each white list corresponds to only a part of PLMNs supported by the current cell.
For example, in a case that the current cell supports PLMN1, PLMN2, and PLMN3 (i.e., M ═ 3), the white list information may include a white list 1 and a white list 2, where the white list 1 corresponds to the PLMN1 and the white list 2 corresponds to the PLMN2 and the PLMN 3; in this case, if the registered PLMN of the terminal is PLMN1 (i.e., first PLMN), the terminal may determine a cell for cell reselection based on the white list 1, and likewise, when the registered PLMN of the terminal is PLMN2 or PLMN3, the terminal may determine a cell for cell reselection based on the white list 2.
It should be noted that, when the information indicating the correspondence between the white lists and the PLMNs includes the correspondence between each white list in the at least one white list and the PLMN, the information indicating the correspondence between the white lists and the PLMNs may include a white list identifier of the PLMN, and the white list identifier is used to indicate the white list corresponding to the PLMN. For example, the white list information includes a white list 1 and a white list 2, and information indicating a corresponding relationship between the white list 1 and the PLMN1, the information indicating a corresponding relationship between the white list 1 and the PLMN1 may include a white list identifier of the PLMN1, a white list identifier of the PLMN1 is used to indicate the white list 1, and if the white list identifier is the number 1 of the white list 1, and so on.
In addition, the information for indicating the correspondence between the white list and the PLMN includes first indication information of at least one PLMN, and the first indication information is used to indicate whether the PLMN has a corresponding white list, which may include at least the following two cases:
in case one, the white list information only includes a white list and first indication information of at least one PLMN, and the second PLMN corresponds to the white list when the first indication information of the second PLMN is used to indicate that the second PLMN has a corresponding white list; and under the condition that the first indication information of the second PLMN is used for indicating that the second PLMN does not have the corresponding white list, the second PLMN does not have the corresponding white list. The second PLMN is any PLMN in the at least one PLMN.
For example, when the current cell supports PLMN1, PLMN2, and PLMN3 (that is, M is 3), the white list information includes white list 4, first indication information of PLMN1, first indication information of PLMN2, and first indication information of PLMN3, and if the first indication information of PLMN1 is used to indicate that a corresponding white list exists in PLMN1, PLMN1 and white list 4 have a corresponding relationship; if the first indication information of the PLMN2 is used to indicate that the PLMN2 does not have a corresponding white list, the PLMN2 does not have a corresponding relationship with the white list 4.
In case two, the white list information includes a plurality of white lists, indication information of at least one PLMN, and a white list identifier of the PLMN, where the white list identifier of the PLMN is used to: and indicating the white list corresponding to the PLMN under the condition that the first indication information of the PLMN is used for indicating that the corresponding white list exists in the PLMN.
For example, in the case that the current cell supports PLMN1, PLMN2, and PLMN3, the white list information may include a white list 1, a white list 2, first indication information of PLMN1, first indication information of second PLMN2, and a white list identifier of PLMN2, and the first indication information of PLMN1 is used to indicate that there is no corresponding white list for PLMN1, the first indication information of PLMN2 is used to indicate that there is a corresponding white list for PLMN2, and the white list identifier of PLMN2 is used to indicate that PLMN2 corresponds to the white list 1.
It should be noted that the first indication information may be any information used for indicating whether a corresponding white list exists in a PLMN, for example, the first indication information may be an indication bit, and is used for indicating that the corresponding white list exists in the PLMN when the indication bit takes a value of 1, and is used for indicating that the corresponding white list does not exist in the PLMN when the indication bit takes a value of 0, and the like.
In addition, the cell for cell reselection may be understood as a cell that satisfies a reselection condition, and the determining, by the terminal in this embodiment, whether the cell satisfies the reselection condition may be: the terminal measures the signal quality of the current cell and the signal quality of the neighboring cell, and determines whether the neighboring cell meets the reselection condition according to the signal quality of the current cell and the signal quality of the neighboring cell, specifically, the cell meeting the S criterion and the R criterion of cell reselection may be used as a cell for cell reselection, where the S criterion and the R criterion of cell reselection are well known in the art and are not described herein again.
After determining the cell for cell reselection in step 102, the terminal further needs to use the cell for cell reselection as an alternative cell, and determine a cell that meets other reselection conditions as a target cell for reselection among the alternative cells, that is, the target cell is a cell where the terminal can camp on and obtain normal service.
The above-mentioned cell for cell reselection is taken as an alternative cell, and a target cell is determined in the alternative cell, where the terminal may rank according to the signal quality of each alternative cell, that is, a cell for cell reselection, and first determine whether the alternative cell with the strongest signal quality satisfies other reselection conditions according to the signal quality, and if the alternative cell with the highest signal quality satisfies a condition for determining a reselected target cell, take the alternative cell with the highest signal quality as the target cell; and if the candidate cell with the strongest signal quality does not meet the condition for confirming the reselected target cell, determining whether the next candidate cell in the sequence meets the condition for confirming the reselected target cell or not until the target cell is determined in the sequence.
In addition, the reselection target cell confirmation condition may include: the cell is not barred for attachment (bar) and the broadcasted Tracking Area (TA) information of the cell does not belong to at least one of a barred TA Area (list of "Forbidden Tracking Areas"), a PLMN of the cell supporting the UE, and the like.
In this embodiment, the white list included in the white list information may be an exclusive white list or a non-exclusive white list, and specifically, when the white list included in the white list information is a non-exclusive white list, the cell used for cell reselection is: in the case that cells meeting reselection conditions exist in the non-exclusive white list, determining the cells in the non-exclusive white list; or, in the case that there is no cell satisfying the reselection condition in the non-exclusive white list, determining a cell by a cell outside the non-exclusive white list.
Here, when the white list is a non-exclusive white list, when the terminal determines a cell for cell reselection based on the non-exclusive white list, the terminal may preferentially determine the cell for cell reselection in the non-exclusive white list, and when the cell satisfying the reselection condition does not exist in the non-exclusive white list, that is, the cell for cell reselection does not exist, the terminal may further determine the cell for cell reselection in cells other than the non-exclusive white list, so that the selection range of the cell for cell reselection is wider, and a more appropriate cell for cell reselection can be determined.
Of course, in other embodiments, in a case that the white list included in the white list information is an exclusive white list, the cell for cell reselection is: only cells determined in the exclusive white list.
Here, in the case where the white list is an exclusive white list, when the terminal determines cells for cell reselection based on the exclusive white list, the terminal selects cells for cell reselection only among the cells within the exclusive white list, thereby making the setting of the white list more flexible.
For example, in a case that the white list information only includes a non-exclusive white list, and the non-exclusive white list includes k cells, where k is a positive integer, if the terminal determines that none of the k cells satisfies the reselection condition, the terminal searches for a cell satisfying the reselection condition among cells outside the non-exclusive white list, and determines at least one cell satisfying the reselection condition outside the non-exclusive white list as a cell for cell reselection.
Of course, in a case that the white list information includes at least one white list and information indicating a correspondence relationship between the white list and the PLMN, any one of the at least one white list may be an exclusive white list or a non-exclusive white list, which is not limited herein.
For example, in a case where the current cell supports PLMN1, PLMN2, and PLMN3 (that is, M is 3), the white list information may include white list 1 and white list 2, and white list 1 corresponds to PLMN1, and white list 2 corresponds to PLMN2, PLMN3, and white list 1 is a non-exclusive white list, and white list 2 is an exclusive white list, then, in a case where the PLMN registered by the terminal is PLMN1, if the terminal determines that there are cells satisfying the reselection condition in white list 1, at least one cell satisfying the reselection condition in white list 1 is determined as a cell for cell reselection, and if there are no cells satisfying the reselection condition in white list 1, cells satisfying the reselection condition outside white list 1 are determined as cells for cell reselection; in case that the PLMN registered by the terminal is PLMN2 or PLMN3, the terminal determines a cell for cell reselection only in white list 2.
It should be noted that, when the terminal determines a cell to be used for cell reselection based on the exclusive white list, the terminal may not perform cell reselection if there is no cell satisfying the reselection condition in the exclusive white list.
In addition, in some embodiments, the white list information further includes second indication information, and the second indication information is used to indicate that the white list of the white list information is the non-exclusive white list or the exclusive white list, so that the terminal may determine that the white list of the white list information is the non-exclusive white list or the exclusive white list according to the second indication information.
It should be noted that the second indication information may be any information for indicating that the white list is a non-exclusive white list or an exclusive white list, for example, it may indicate that the bit takes a value of 0 or 1, and that taking a value of 0 indicates an exclusive white list, and that taking a value of 1 indicates a non-exclusive white list, and so on.
In this embodiment, under the condition that the white list information includes a white list, the cell in the white list information may be a cell on one frequency point or a cell on multiple frequency points, that is, the white list includes cells of multiple frequency points.
In some embodiments, the white list information includes a first white list, and the first white list includes cells of a plurality of frequency points;
the determining a cell for cell reselection based on the white list information may include:
determining a cell for cell reselection in X cells under the condition that the cells meeting reselection conditions exist in the X cells on a first frequency point, wherein the first frequency point is a frequency point in the multiple frequency points, the X cells are cells in the first white list, and X is a positive integer; or
Determining that the cells except the X cells are used for cell reselection under the condition that the cells meeting reselection conditions do not exist in the X cells.
Here, the terminal may determine the cell used for cell reselection according to the white list and the frequency point where the cell in the white list is located, so that a more appropriate cell used for cell reselection may be determined.
In this embodiment, the first frequency point may be any frequency point in a plurality of frequency points, for example, the first frequency point may be a frequency point with the highest priority among the plurality of frequency points.
In addition, the determining that the cells other than the X cells are cells for cell reselection may be determining, in the cells other than the X cells on the first frequency point, at least one cell that satisfies a reselection condition as a cell for cell reselection; or, in a frequency point of the next priority, determining at least one cell satisfying the reselection condition as a cell for cell reselection, and so on.
Specifically, the first white list is an exclusive white list;
in a case that it is determined that there is no cell satisfying a reselection condition among the X cells, the cell for cell reselection is: under the condition that cells meeting reselection conditions exist in cells of which the second frequency points are located in the first white list, determining the cells on the second frequency points;
and the second frequency point is a frequency point with the reselection priority equal to or lower than that of the first frequency point.
Here, in the process that the terminal determines the cell for cell reselection based on the exclusive white list in the white list information, it may be preferentially determined whether a cell satisfying the reselection condition exists at a first frequency point with a high reselection priority in the exclusive white list, and in the case that the cell satisfying the reselection condition does not exist at a frequency point with a high reselection priority, the cell for cell reselection is determined at a second frequency point with the same or lower reselection priority, so that the terminal may select a more appropriate cell for cell reselection.
For example, the white list 2 in the white list information is an exclusive white list, the white list 2 includes cells of N frequency points whose reselection priorities are sequentially reduced, and in a process that the terminal determines the cells for cell reselection based on the white list 2, the terminal may first determine whether the cells on the 1 st frequency point on the white list 2 have cells meeting reselection conditions, and if so, determine that at least one cell on the 1 st frequency point on the cells on the white list 2 that meets the reselection conditions is the cell for cell reselection; if not, continuously determining whether cells meeting reselection conditions exist in the cells on the 2 nd frequency point in the white list 2, and if so, determining at least one cell meeting reselection conditions in the cells on the 1 st frequency point in the white list 2 as a cell for cell reselection; and if not, continuously determining whether the cells meeting the reselection conditions exist in the cells in the white list 2 on the frequency point of the next reselection priority, and stopping when determining the cells for cell reselection in the cells of one frequency point of the N frequency points or determining that the cells meeting the reselection conditions do not exist in the white list 2.
In another embodiment, the first whitelist is a non-exclusive whitelist;
in a case where it is determined that there is no cell satisfying a reselection condition among the X cells, the cell for cell reselection may be:
under the condition that cells meeting reselection conditions exist in the cells which are located on the first frequency point and outside the first white list, determining the cells in the cells which are located on the first frequency point and outside the first white list; or
And under the condition that no cell meeting the reselection condition exists in the cells on the first frequency point and outside the first white list, and a second frequency point exists in the cells in the first white list, a cell determined in the cells on the second frequency point and in the first white list exists.
Alternatively, in another embodiment, the first whitelist is a non-exclusive whitelist;
in the case that it is determined that there is no cell satisfying the reselection condition among the X cells, the cell for cell reselection may be further:
under the condition that cells meeting reselection conditions exist in cells on a second frequency point and located in the first white list, determining cells in the cells on the second frequency point and located in the first white list; or
Under the condition that no cell meeting reselection conditions exists in cells of all frequency points in the first white list, determining a cell in a cell outside the first white list;
and the second frequency point is a frequency point with the reselection priority equal to or lower than that of the first frequency point.
Here, in the process that the terminal determines a cell for cell reselection based on the non-exclusive white list in the white list information, the terminal may further determine a cell on the frequency point with the high priority and outside the non-exclusive white list as a cell for cell reselection when there is no cell satisfying the reselection condition on the frequency point with the high priority and in the non-exclusive white list; or, under the condition that all the cells on all the frequency points and in the non-exclusive white list do not meet the reselection condition, determining the cells in the cells except the non-exclusive white list, so that the search range of the cells for cell reselection is wider, and the cells for cell reselection can be easily determined to be suitable.
As can be seen from the above, when the first white list is a non-exclusive white list, if the terminal determines that there is no cell satisfying the reselection condition in the cells on the first frequency point with the high reselection priority and in the first white list, the terminal may determine the cell for cell reselection in the cells on the first frequency point and outside the first white list in the following first and second manners:
the method comprises the steps that a terminal detects whether cells meeting reselection conditions exist in cells which are located on a first frequency point and outside a first white list, and if the cells meet the reselection conditions, the cells used for cell reselection are preferentially determined in the cells which are located on the first frequency point and outside the first white list; and if not, determining a cell for cell reselection in cells on a second frequency point with the same priority or low priority and located in the first white list.
In a first manner, the determining, in the cells on the first frequency point and outside the first white list, the cell for cell reselection may be to detect, by the terminal, whether the cell on the first frequency point and outside the first white list satisfies a reselection condition, and use K cells that satisfy the reselection condition as reselection candidate cells, where K is specified by a network configuration or a protocol, and determine, in the reselection candidate cells, a cell as a cell for cell reselection, for example, may be to randomly select and reselect a cell from the reselection candidate cells to determine the cell as a cell for cell reselection. Of course, if the number of cells meeting the reselection condition in the cells located on the first frequency point and outside the first white list is H, and H is smaller than K, the terminal may also use the H cells meeting the reselection condition as the reselection candidate cells.
It should be noted that, under the condition that the cells on the second frequency point (including the cells located in the first white list and the cells located outside the white list) do not satisfy the reselection condition, the terminal continues to detect whether a cell of the next frequency point (that is, another frequency point having the same or lower reselection priority as the second frequency point) has a cell satisfying the reselection condition, until a cell for the cell reselection condition is found in the multiple frequency points, or when no cell satisfying the reselection condition exists in the multiple frequency points, the terminal may further determine a cell for cell reselection in the cells outside the first white list.
For example, a white list 1 included in the white list information is a non-exclusive white list, the white list 1 includes a part of cells of a frequency point 1, a part of cells of a frequency point 2, and a part of cells of a frequency point 3, and reselection priorities of the frequency point 1, the frequency point 2, and the frequency point 3 are sequentially reduced, and if there is no cell satisfying the reselection condition in the cells in the white list 1 on the frequency point 1, if there is a cell satisfying the reselection condition in the cells out of the white list 1 on the frequency point 1, a cell for cell reselection is determined in the cells satisfying the reselection condition out of the white list 1 on the frequency point 1; if the cells which meet the reselection condition do not exist in the cells which are positioned outside the white list 1 on the frequency point 1, determining whether the cells which meet the reselection condition exist in the cells which are positioned in the white list 1 on the frequency point 2, and if so, determining the cells for cell reselection in the cells which are positioned in the white list 1 on the frequency point 2; if the cell does not exist, and the cell which is positioned outside the white list 1 on the frequency point 2 has the cell which meets the reselection condition, determining the cell for cell reselection by the cell which is positioned outside the white list 1 on the frequency point 2; if the cells which meet the reselection condition do not exist in the cells which are located outside the white list 1 on the frequency point 2, continuously determining whether the cells which meet the reselection condition exist in the cells on the frequency point 3 until the cells for cell reselection are determined on the frequency point 3, or determining the cells for cell reselection in the cells which meet the reselection condition outside the white list 1 under the condition that the cells which meet the reselection condition do not exist on the frequency point 3.
