Abstract

The invention discloses a cell reselection method, a base station, a user terminal and a storage medium, which relate to the technical field of communication.

Description

Cell reselection method, base station, user terminal and storage medium

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a cell reselection method, a base station, a user terminal and a storage medium.

Background

Currently, radio spectrum resources are allocated uniformly by the country. The wireless spectrum resources include spectrum in licensed bands and spectrum in unlicensed bands. The spectrum of the licensed band is pre-allocated for use by a particular operator. The spectrum of the unlicensed frequency band does not need to be allocated, and all organizations and individuals can use the spectrum, so that the spectrum is a shared spectrum resource.

The user terminal generally has strong mobility. As the user terminal moves, the signal quality of the cell in which the user terminal currently resides may deteriorate, resulting in the cell selection criterion not being satisfied. The user terminal needs to perform cell reselection.

When a user terminal tries to reselect a reselection target cell with signal quality meeting reselection requirements from a resident cell, the user terminal needs to read system information of the reselection target cell to determine whether a P L MN supported by the reselection target cell is matched with a P L MN selectable by the user terminal or not.

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.

The embodiment of the invention provides a cell reselection method, a base station, a User terminal and a storage medium, which can be used between the base station corresponding to a certain cell and a User Equipment (UE) connected with the cell, wherein in the embodiment of the invention, the base station can be a base station in a long Term Evolution (L ong Term Evolution, L TE) communication system, or can be a base station in a 5G communication system, but is not limited thereto.

Fig. 1 is a flowchart of a cell reselection method according to an embodiment of the present invention. The cell reselection method is applicable to a base station. As shown in fig. 1, the cell reselection method may include step S101.

In step S101, a configuration parameter of a neighboring cell of the subordinate cell is broadcast by the subordinate cell.

The method comprises the steps that a cell formed by signal coverage of a base station is a cell under the jurisdiction of the base station, one base station can possibly control a plurality of cells, cells adjacent to the cell under the jurisdiction are adjacent cells of the cell under the jurisdiction, one cell under the jurisdiction can be provided with one or a plurality of adjacent cells, configuration information of each adjacent cell comprises a cell identifier of the adjacent cell and a P L MN identifier set of the adjacent cell, and the base station broadcasts configuration parameters of one or a plurality of adjacent cells of the cell under the jurisdiction through each cell under the jurisdiction.

Wherein the cell identifier is used for identifying the cell. Different cells have different cell identities. In some examples, the Cell identity includes a Cell operating frequency point and a Physical Cell Identity (PCI). For example, the cell operating frequency point may specifically be a frequency point at which a cell transmits a Synchronization Signal Block (SSB).

The P L MN identity set comprises at least one P L MN identity, the form of the P L MN identity set is not limited herein, and for example, the P L MN identity list (i.e. P L MN ID list), the P L MN identity array, the P L MN queue and the like can be used.

The method comprises the steps that P L MN information can be mutually transmitted among base stations through an interface, so that the base stations can obtain configuration information of a neighboring cell of a cell under the jurisdiction, P L MN information of the neighboring cell of the cell under the jurisdiction can also be read by a user terminal connected to the cell under the jurisdiction through configuration, the P L MN information is reported to the base stations of the cell under the jurisdiction, so that the base stations can obtain configuration parameters of the neighboring cell of the cell under the jurisdiction, P L MN information of the neighboring cell can also be obtained through a manual drive test method, and the P L MN information of the neighboring cell is configured to the base stations through Operation Administration and Maintenance (OAM), so that the base stations can obtain the configuration parameters of the neighboring cell of the cell under the jurisdiction.

In the embodiment of the invention, a base station broadcasts the configuration parameters of the adjacent cells of the cell under jurisdiction through the cell under jurisdiction, so that a user terminal can acquire the configuration parameters of the adjacent cells, wherein the configuration parameters of each adjacent cell comprise the cell identification of the adjacent cell and the P L MN identification set of the adjacent cell, the user terminal can acquire the P L MN identification of the adjacent cell without reading the system information broadcasted by the adjacent cell, thereby avoiding the determination of the alternative cells of multiple cell reselections which can be possibly performed by the user terminal because the P L MN identification can not be known before the system information broadcasted by the adjacent cell is read under the condition of an unauthorized frequency band, improving the cell reselecting efficiency, and reducing the time delay of the cell of the user terminal.

Fig. 2 is a flowchart illustrating another cell reselection method according to an embodiment of the present invention. The cell reselection method is applicable to a user terminal. As shown in fig. 2, the cell reselection method may include steps S201 and S202.

In step S201, configuration parameters of neighboring cells of the camped cell are acquired from the camped cell.

The user terminal may need to select a suitable camping cell through cell reselection during moving, i.e. change the camping cell. The resident cell in this embodiment is a cell where the user terminal currently resides. At the current moment, the user terminal can receive the information broadcasted by the resident cell.

The user terminal can obtain the configuration parameters of the neighbor cells of the resident cell from the System Information (i.e. System Information) broadcasted by the resident cell, i.e. the System Information comprises the configuration parameters of the neighbor cells of the resident cell, the configuration parameters of the neighbor cells comprise the cell identification of the neighbor cells and the P L MN identification set of the neighbor cells, the P L MN identification set comprises at least one P L MN identification.

In some examples, the cell identity includes a cell operating frequency point and a physical cell identity.

In some examples, the P L MN identity set is a list of P L MN identities.

For the configuration parameters of the neighboring cell, the P L MN identity set, and the related descriptions of other contents in step S201, reference may be made to the related contents in the above embodiments, which are not described herein again.

It should be noted that the ue in the embodiment of the present invention is in an idle state (i.e., ID L E state) or an Inactive state (i.e., Inactive state).

In step S202, an alternative cell for cell reselection is determined according to the configuration parameters of the neighboring cells.

The configuration parameters of the adjacent cell comprise the cell identifier of the adjacent cell and the P L MN identifier set of the adjacent cell, concretely, the user terminal can match the P L MN identifier set of the adjacent cell with the P L MN identifier of the user terminal, and determines an alternative cell for cell reselection based on the cell identifier of the adjacent cell.

Specifically, the user terminal determines an alternative cell for cell reselection, and then the user terminal may select a neighboring cell from the alternative cells for cell reselection to camp on (i.e., camp on) — it should be noted that a suitable cell (i.e., a viable cell) may be determined from the alternative cells for cell reselection, and the suitable cell is a cell where the user terminal may camp on and obtain normal services.

The user terminal can obtain the P L MN ID of the adjacent cell without reading the system information broadcasted by the adjacent cell, avoiding the possible determination of the alternative cell for multiple times of cell reselection due to the fact that the user terminal can not know the P L MN ID before reading the system information broadcasted by the adjacent cell under the condition of unauthorized frequency band, thereby improving the cell reselection efficiency.

In some examples, at least one P L MN identity in the P L MN identity set of the candidate cell for cell reselection in the above embodiments is the same as the P L MN identity of the user terminal, that is, at least one P L MN identity in the P L MN identity set is the same as the P L MN identity of the user terminal, which can be used as the candidate cell for cell reselection.

For example, at least one P L MN identifier in the P L MN identifier set of the candidate cell for cell reselection is the same AS the identifier of a P L MN (i.e., Selected P L MN) Selected by the user terminal, an Access Stratum (AS) of the user terminal may report the acquired information related to the P L MN to the NAS by itself or based on a received Non-Access Stratum (NAS) instruction, the user terminal searches for a cell with the strongest signal quality and confirms the cell with the strongest signal quality, and the user terminal reports one or more P L MN identifiers read in the cell with the strongest signal quality to the NAS, where the identifier of the P L MN Selected by the NAS is the P L identifier Selected by the user terminal.

For another example, at least one P L MN identifier in the P L MN identifier set of the candidate cell for cell reselection is the same as the P L MN (i.e., Registered P L MN) identifier Registered by the ue.

For another example, at least one P L MN identifier in the P L MN identifier set of the candidate cell for cell reselection is the same as any P L MN identifier in the Equivalent P L0 MN (i.e., Equivalent P L MN) set of the user terminal.

In some examples, the network may pre-configure the priority of the cell operating frequency points. In the process of cell reselection, the alternative cells reselected by the cells corresponding to the cell working frequency points can be sequentially selected for cell reselection according to the sequence of the priorities of the preconfigured cell working frequency points from high to low until the cell reselection is successful.

There may be a plurality of candidate cells for cell reselection, and the cell identifier in the configuration message of the candidate cell for cell reselection includes a cell operating frequency point. The cell operating frequency points of the candidate cells for the reselection of the plurality of cells may be different. For example, the candidate cells for cell reselection are four, namely neighbor cells X1, X2, X3 and X4. The cell working frequency points of the four adjacent cells are three, namely cell working frequency points F1, F2 and F3. The cell working frequency point of the adjacent cells X1 and X2 is F1, the cell working frequency point of the adjacent cell X3 is F2, and the cell working frequency point of the adjacent cell X4 is F3. And the priority of the pre-configured cell working frequency points is respectively F1, F2 and F3 from high to low. Therefore, in the process of cell reselection, cell reselection evaluation is performed on the neighboring cells X1 and X2. If no suitable cell is obtained in the adjacent cells X1 and X2, the cell reselection evaluation is performed on the adjacent cell X3. If the neighboring cell X3 is not a suitable cell, the cell reselection evaluation is performed again for the neighboring cell X4.

The embodiment of the invention also provides a cell reselection method, which can be applied to a system comprising a base station and a user terminal. The cell reselection method includes step S101, step S201, and step S202 in the above embodiments. For the relevant content of step S101, step S201, and step S202 and the technical effect generated by the method for cell reselection, reference may be made to the relevant description in the foregoing embodiments, and no further description is given here. Note that the subordinate cell in step S101 corresponds to the camping cell in step S201 and step S202.

Fig. 3 is a flowchart of a cell reselection method according to another embodiment of the present invention. The cell reselection method is applicable to a base station. As shown in fig. 3, the cell reselection method may include step S301.

In step S301, cell reselection reference information is broadcasted by a subordinate cell.

The cell reselection reference information comprises cell identifications of matching neighbor cells or cell identifications of non-matching neighbor cells, specifically, the cell identifications of the matching neighbor cells can be presented in a mode of information items in a list, the matching neighbor cells comprise P L MN identifications and neighbor cells of a subordinate cell matched with the P L MN identifications of the subordinate cell, namely, the P L MN identifications of the matching neighbor cells are matched with the P L MN identifications of the subordinate cell, the cell identifications of the non-matching neighbor cells can be presented in a mode of information items in the list, the non-matching neighbor cells comprise P L MN identifications and the P L MN identifications of the subordinate cell are not matched with the neighbor cells of the subordinate cell, namely, the P L MN identifications of the non-matching neighbor cells are not matched with the P L MN identifications of the subordinate cell.

It should be noted that the neighboring cells of the subordinate cell include matching neighboring cells of the subordinate cell, but all neighboring cells of the subordinate cell are not necessarily matching neighboring cells of the subordinate cell. In the embodiment of the invention, if the cell reselection reference information comprises the cell identifier of the matched adjacent cell, the base station only broadcasts the cell identifier of the matched adjacent cell of the subordinate cell through the subordinate cell.

Similarly, the neighboring cells of the subordinate cell include non-matching neighboring cells of the subordinate cell, but the neighboring cells of the subordinate cell are not necessarily all non-matching neighboring cells of the subordinate cell. In the embodiment of the invention, if the cell reselection reference information comprises the cell identifier of the non-matching adjacent cell, the base station only broadcasts the cell identifier of the non-matching adjacent cell of the cell under jurisdiction.

The content related to step S101 in step S301 in the above embodiment can refer to the related description in step S101 in the above embodiment, and is not repeated herein.
