Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a cell adjustment method, apparatus, and device. Background Art

[0002] For high-rise buildings such as high-rise residential areas and office buildings, it is generally necessary to build in-building distribution to ensure effective signal coverage in the indoor environment. However, in the peripheral areas such as the window balconies on the floors, the macro base station signals from the outside are often received. At this time, due to the weak in-building distribution coverage at the floor edge, using the decision criteria of monitoring the Channel Quality Indicator (CQI) value and the Reference Signal Receiving Power (RSPR) value in the existing technology for cell reselection or handover is likely to connect to the outdoor macro base station. However, the macro base station signal may be a sidelobe signal, and the perception of edge users is poor. Summary of the Invention

[0064] Before introducing the cell adjustment method provided by the embodiments of the present application, the prior art that may be involved in the embodiments of the present application will be introduced below.

[0065] In the prior art, the connection to an outdoor macro station is usually achieved through cell reselection or handover. Cell reselection is a process in which a user equipment (UE) selects a best cell to provide a service signal by monitoring the signal quality of neighboring cells and the current cell in the idle mode. Cell handover is a process in which the serving cell changes from one cell to another without interrupting communication when the UE is in a service connection state.

[0066] Embodiment 1

[0067] The cell adjustment method provided by the embodiments of the present application is applicable to the floor edge scenario. This cell adjustment method can be applied to a user terminal or executed by a user terminal. In addition, this cell adjustment method can also be executed by a cell adjustment device, an electronic device, etc. Hereinafter, an example in which this cell adjustment method is executed by a user terminal will be described.

[0068] As Figure 1As shown in the figure, an embodiment of the present application provides a cell adjustment method, which includes steps S110 to S130.

[0069] S110. Obtain a plurality of cell broadcast information corresponding one-to-one to a plurality of neighboring cells; the neighboring cells are cells other than the current cell and adjacent to the current cell; the current cell is the cell where the user terminal currently resides; the cell broadcast information includes the cell type; the cell type includes in-building distribution or macro station.

[0070] S120. When there is at least one neighboring cell with the cell type of in-building distribution and the target user holding the user terminal is an edge user, determine the cell adjustment strategy for the user terminal; the cell adjustment strategy includes the strategy that the residence priority of the in-building distribution is higher than that of the macro station.

[0071] S130. Execute the cell adjustment strategy.

[0072] According to the cell adjustment method provided by the embodiment of the present application, first obtain a plurality of cell broadcast information corresponding one-to-one to a plurality of neighboring cells, and then when there is at least one neighboring cell with the cell type of in-building distribution and the target user holding the user terminal is an edge user, determine the cell adjustment strategy and execute the cell adjustment strategy. That is to say, in the embodiment of the present application, since the cell adjustment strategy includes the strategy that the residence priority of the in-building distribution is higher than that of the macro station, that is, the cell type of the target cell determined according to the cell adjustment strategy is more likely to be the in-building distribution. By making the user terminal reside in the target cell, the edge user preferentially resides in the neighboring cell with the cell type of in-building distribution. Since the usage perception of the edge user in the neighboring cell with the cell type of in-building distribution is stronger than that of the edge user in the neighboring cell with the cell type of macro station, therefore, compared with the prior art in which the user terminal resides in the neighboring cell with the cell type of macro station, it can improve or solve the problem of poor usage perception of the floor edge user.

[0073] The following introduces the specific implementation manners of the above steps.

[0074] In step S110, after the user terminal resides in the current cell, as the target user holding the user terminal moves, the signal strength and quality of the primary serving cell (i.e., the current cell) and neighboring cells (i.e., neighboring cells) received by the user terminal will change continuously. At this time, the user terminal starts to search and measure the signal strength of other surrounding neighboring cells (i.e., neighboring cells) so as to be able to reside in a cell with better signal at any time.

[0075] Exemplarily, when the user terminal performs neighboring cell (i.e., neighboring cell) search, it can read the broadcast information (i.e., cell broadcast information) of each cell (i.e., neighboring cell) and discriminate the cell type of each cell (i.e., neighboring cell).

[0076] In step S120, after the user terminal obtains a plurality of cell broadcast information corresponding to a plurality of neighboring cells one by one, when there is at least one neighboring cell with an in-building distribution cell type and the target user holding the user terminal is an edge user, a cell adjustment strategy can also be determined.

[0077] Exemplarily, the target cell can be the next cell where the user terminal will camp.

[0078] It should be noted that when there is no neighboring cell with an in-building distribution cell type, regardless of whether the target user is an edge user, the neighboring cell with a macro cell type will be used as the target cell.

[0079] In some embodiments, before determining the target cell from a plurality of neighboring cells according to the cell adjustment strategy, the method further includes:

[0080] Obtaining the target positioning data of the user terminal and the user behavior data, where the target positioning data includes at least one of satellite positioning data and base station positioning data, and the user behavior data is used to indicate the action trajectory and action time of the target holding the user terminal;

[0081] According to the target positioning data and the user behavior data, determining whether the target user is in the in-building distribution edge area to obtain a determination result;

[0082] According to the determination result, determining whether the target user is an edge user.

[0083] In this embodiment, through the target positioning data and the user behavior data, it is possible to accurately determine whether the target user is an edge user, thereby providing a basis for subsequently determining the target cell from a plurality of neighboring cells according to the cell adjustment strategy.

[0084] Exemplarily, the satellite positioning data can include data sourced from the Global Navigation Satellite System and capable of determining the location of the user terminal.

[0085] Exemplarily, the base station positioning data can include data obtained through the mobile communication network and capable of determining the location of the user terminal.

[0086] As an example, the target positioning data includes satellite positioning data; as another example, the target positioning data includes base station positioning data; as still another example, the target positioning data includes satellite positioning data and base station positioning data.

[0087] Exemplarily, the determination result includes that the target user is in the in-building distribution edge area, or the target user is not in the in-building distribution edge area.

[0088] Exemplarily, the user terminal is built-in with a Global Positioning System (GPS) or a Beidou chip, and obtains satellite positioning data through the GPS or Beidou chip.

[0089] Exemplarily, the user terminal can automatically detect the surrounding base station signals to obtain the base station identifier (ID), signal strength, and time difference; then, based on the base station ID, signal strength, and time difference, a triangulation algorithm is used to calculate the base station positioning data.

[0090] Exemplarily, the user terminal is equipped with an acceleration sensor and a three-axis gyroscope, and can obtain user behavior data through the acceleration sensor and the three-axis gyroscope.

[0091] Exemplarily, based on the target positioning data and user behavior data, the current coordinates of the target user are determined; if the current coordinates are within the preset coordinate range, it is determined that the result is that the target user is in the in-building distribution edge area; if the current coordinates are not within the preset coordinate range, it is determined that the result is that the target user is not in the in-building distribution edge area. Among them, the preset coordinate range is the coordinate range of the in-building distribution edge area set in advance.

[0092] In some examples, the edge users include temporary edge users and permanent edge users;

[0093] According to the determination result, it is determined whether the target user is an edge user, specifically including:

[0094] In the case where the determination result includes that the target user is in the in-building distribution edge area,

[0095] If the current stay duration of the target user in the in-building distribution edge area is less than or equal to the first preset value, and the target distance change amount is less than the preset distance, it is determined that the target user is a temporary edge user, and the target distance change amount is the distance change amount between the location of the target user and the geometric center of its affiliated building;

[0096] Or,

[0097] If the current stay duration of the target user in the in-building distribution edge area is greater than the first preset value, it is determined that the target user is a permanent edge user.

[0098] In this example, through the relationship between the current stay duration of the target user in the in-building distribution edge area and the first preset value, the type of the edge user can be determined quickly and accurately.

[0099] It should be noted that both the first preset value and the preset distance can be set according to the actual situation and are not limited here. For example, the first preset value can be 10 minutes, 30 minutes, 1 hour, etc., and the preset distance can be 1 meter, 2 meters, 5 meters, etc.

[0100] Exemplarily, the current sojourn duration can be obtained from user behavior data.

[0101] Exemplarily, according to the target positioning data and user behavior data, multiple first coordinates of the target user at different times are determined. For each first coordinate, the distance between it and the second coordinate is determined to obtain multiple target distance change amounts, where the second coordinate is the coordinate of the geometric center of the building to which the target user belongs. In the embodiments of the present application, the coordinates can be longitude and latitude coordinates.

[0102] It should be added that in the case where the determination result includes that the target user is in the in-building distribution edge area, if the current sojourn duration of the target user in the in-building distribution edge area is less than or equal to the first preset value and the target distance change amount is greater than the preset distance, it is determined that the target user is not an edge user; in the case where the determination result includes that the target user is not in the in-building distribution edge area, it is determined that the target user is not an edge user.

[0103] Exemplarily, when the user terminal first searches for an in-building distribution signal (i.e., a neighboring cell with the cell type of in-building distribution), according to the satellite positioning data, base station positioning data, and user behavior data, the action time and trajectory of the user (i.e., the target user) under the in-building distribution coverage are recorded to determine whether the user is an edge user. Edge users are further divided into temporary edge users and permanent edge users. User behavior data can be obtained through the acceleration sensor and three-axis gyroscope of the user terminal.

[0104] In some examples, in the case where the target user is determined to be a temporary edge user, the method further includes:

[0105] Adding the International Mobile Equipment Identity (IMEI) of the user terminal to the temporary edge user list;

[0106] In the case of meeting the first condition or the second condition, deleting the International Mobile Equipment Identity of the user terminal from the temporary edge user list; the first condition includes that the current sojourn duration is less than or equal to the first preset value and it is detected that the target user leaves the in-building distribution edge area; the second condition includes that the current sojourn duration is greater than or equal to the first preset value;

[0107] Or,

[0108] In the case where the target user is determined to be a permanent edge user, the method further includes:

[0109] Adding the International Mobile Equipment Identity of the user terminal to the permanent edge user list.

[0110] In this example, the International Mobile Equipment Identity (IMEI) of the user terminal is added to the temporary edge user list to better adjust the temporary edge users; when the first condition or the second condition is met, the IMEI of the user terminal is removed from the temporary edge user list to reduce the maintenance of unnecessary temporary data, reduce storage and processing overheads, and ensure the effective utilization of storage resources.

[0111] That is to say, when the user first enters the coverage area of the in-building distribution cell (i.e., the neighboring cell with the in-building distribution cell type), the user terminal determines the user's movement trajectory and time based on the data from the acceleration sensor and the triaxial gyroscope. Combining the satellite positioning data and the base station positioning data, it identifies whether the user is in the in-building distribution edge area. Each building with in-building distribution coverage has the longitude and latitude of the geometric center point of the building. When the user moves in the edge area of the in-building distribution cell and the change in the distance from the geometric center point of the building does not exceed 5 meters, the user is determined as a temporary edge user, and the IMEI number of the user terminal is added to the temporary edge user list. When the residence time of the user terminal within this range (i.e., the current residence duration) exceeds one hour, the user is classified as a permanent edge user, and at the same time, the IMEI number of the user terminal is transferred to the permanent edge user list and maintained for a long time.

[0112] It should be noted that when the target user in the permanent edge user list reselects or switches when entering the in-building distribution area next time, it can be considered that the target user is a permanent edge user, and the cell adjustment is directly performed according to the cell adjustment strategy in step S120 without re-determining whether it is an edge user based on the target positioning data and the user behavior data.

[0113] In some embodiments, determining the cell adjustment strategy of the user terminal specifically includes:

[0114] Determine the cell adjustment strategy of the user terminal according to the current state of the user terminal.

[0115] In this embodiment, when determining the cell adjustment strategy of the user terminal, by considering the current state of the user terminal, the rationality of determining the cell adjustment strategy of the user terminal can be improved.

[0116] In some examples, the current state includes the idle state or the connected state;

[0117] Determine the cell adjustment strategy of the user terminal according to the current state of the user terminal, specifically including:

[0118] When the current state of the user terminal is the idle state, determine the cell adjustment strategy of the user terminal according to the preset conditions;

[0119] Or,

[0120] When the current state of the user terminal is a connected state, the cell adjustment strategy of the user terminal is determined according to the moving direction of the target user.

[0121] In this example, when the current state of the user terminal is an idle state, the rationality of determining the cell adjustment strategy of the user terminal can be improved by considering the preset conditions; when the current state of the user terminal is a connected state, the rationality of determining the cell adjustment strategy of the user terminal can be improved by considering the moving direction of the target user.

[0122] In some examples, the cell adjustment strategy includes a first strategy, a second strategy, and a third strategy;

[0123] According to the preset conditions, the cell adjustment strategy of the user terminal is determined, which specifically includes:

[0124] In the case where there is only one target neighboring cell, determining the cell adjustment strategy of the user terminal to be the first strategy; the first strategy includes determining the target neighboring cell as the target cell; the target neighboring cell includes a neighboring cell whose cell type is indoor and meets a preset condition; the preset condition includes that the S value of the neighboring cell is greater than or equal to a preset threshold value;

[0125] or,

[0126] In the case where there are multiple target neighboring cells, determining the cell adjustment strategy of the user terminal as a second strategy; the second strategy includes determining the target neighboring cell with the highest priority as the target cell, or determining the target neighboring cell with the highest priority frequency as the target cell, or determining the target cell from multiple target neighboring cells with the same priority frequency or frequency according to the R criterion;

[0127] or,

[0128] In the case that there is no target neighboring cell, the cell adjustment strategy of the user terminal is determined to be a third strategy, and the third strategy includes determining a neighboring cell with the highest priority frequency as the target cell.

[0129] In this example, through the above method, the cell type of the target cell determined according to the cell adjustment strategy is more likely to be indoor, and the user terminal is stationed in the target cell, so that the edge users preferentially reside in the neighboring cell whose cell type is indoor. Since the edge user usage perception of the neighboring cell whose cell type is indoor is stronger than the edge user usage perception of the neighboring cell whose cell type is macro station, compared with the prior art of stationing the user terminal in the neighboring cell whose cell type is macro station, the problem of poor usage perception of the edge users on the floor can be further improved or solved.

[0130] Exemplarily, the S value can be the basic criterion for determining whether a cell (i.e., a neighboring cell) meets the residence condition, including two dimensions: signal strength and signal instruction.

[0131] Exemplarily, the R criterion can be an evaluation criterion for comparing the signal quality of the serving cell (i.e., the current cell) with that of the neighboring cell (i.e., the neighboring cell), and the cell priority is calculated through a formula to determine whether to trigger reselection.

[0132] Exemplarily, the preset threshold value is less than the minimum received level set by the S criterion. Under the above conditions, the preset threshold value can be set according to the actual situation and is not limited here. For example, the preset threshold value can be -10 dB, -12 dB, etc.

[0133] Exemplarily, the highest priority can be a strategy for the network to guide the user terminal to preferentially select a specific frequency point or cell through parameter configuration, aiming to optimize resource allocation, improve the user experience and network efficiency.

[0134] Exemplarily, the highest priority frequency can be that the network assigns priorities (0 - 7, with 0 having the lowest priority) to different frequency points through system messages or dedicated signaling, and the user terminal selects a high-priority frequency point to reside.

[0135] That is to say, for edge users, when performing cell reselection or handover, first ignore the macro station signal (i.e., the neighboring cell with the cell type of macro station), and select among the in-building distribution system (IBS) cell signals (i.e., the neighboring cell with the cell type of IBS). When the signal strengths of all IBS cells cannot meet the conditions (i.e., the preset conditions), the user terminal starts to consider the macro station cell (i.e., the neighboring cell with the cell type of macro station) for residence.

[0136] Exemplarily, when the user terminal is in the idle state, the position change of the user (i.e., the target user) may cause the terminal (i.e., the user terminal) to perform cell reselection.

[0137] 1) If multiple neighboring IBS cells (i.e., the neighboring cells with the cell type of IBS) on the highest priority meet the conditions (i.e., the preset conditions), then select the optimal IBS cell on the highest priority frequency. For equally prioritized frequency points (or the same frequency), the R criterion for intra-frequency cell reselection is adopted.

[0138] 2) When all IBS cells (i.e., the neighboring cells with the cell type of IBS) do not meet the conditions, that is, the S values of all measured IBS cells are less than the preset threshold value, then consider the macro station cell (i.e., the neighboring cell with the cell type of macro station) together, and select the best cell with the highest priority frequency among all cells (i.e., multiple neighboring cells) for residence. The preset threshold value should be less than the minimum received level set by the S criterion.

[0139] In some other examples, the cell adjustment strategy includes a fourth strategy and a fifth strategy; the moving direction includes a first moving direction or a second moving direction, the first moving direction is the direction of moving from the outdoor towards the indoor distributed edge area, and the second moving direction is the direction of moving from the indoor distributed edge area towards the outdoor;

[0140] Determine the cell adjustment strategy of the user terminal according to the moving direction of the target user, specifically including:

[0141] When the moving direction of the target user is the first moving direction, determine that the cell adjustment strategy of the user terminal is the fourth strategy. The fourth strategy includes, in the case of a handover event, issuing a first instruction, and the first instruction is an instruction for instructing the base station to equip the user terminal with an entry offset, and the entry offset is less than the offset of the A3 handover event;

[0142] Or,

[0143] When the moving direction of the target user is the second moving direction, determine that the cell adjustment strategy of the user terminal is the fifth strategy. The fifth strategy includes, in the case of a handover event, issuing a second instruction, and the second instruction is an instruction for instructing the base station to equip the user terminal with a departure offset, and the departure offset is greater than the offset of the A3 handover event.

[0144] In this example, by equipping the user terminal with different entry offsets in the case of different moving directions, the user terminal can more easily camp on a cell with the cell type of indoor distribution, that is, make the edge users preferentially camp on the neighboring cells with the cell type of indoor distribution. Since the usage perception of the edge users of the neighboring cells with the cell type of indoor distribution is stronger than that of the edge users of the neighboring cells with the cell type of macro station, compared with the prior art in which the user terminal camps on the neighboring cells with the cell type of macro station, the problem of poor usage perception of the floor edge users can be further improved or solved.

[0145] Exemplarily, the A3 handover event is a core handover mechanism triggered based on signal quality comparison in the mobile communication network, and is used for the user terminal to switch from the current serving cell (i.e., the current cell) to a neighboring cell (i.e., the neighboring cell) with better signal.

[0146] That is to say, when the user (i.e., the target user) is in the connected state, the change of the user's position may cause the terminal to perform a cell handover.

[0147] 1) If the user moves from the outdoor towards the indoor distributed edge area, the user will be judged as a temporary edge user. When a handover event occurs, the base station equips the users in the list (i.e., the temporary edge user list and the resident edge user list) with an entry offset, and this entry offset needs to be smaller than the A3 handover event offset, so that the user terminal can more easily switch to the indoor distributed cell.

[0148] 2) When the user moves from the edge area of the in-building distribution towards the outdoor, when a handover event occurs, the base station assigns a far offset to the users in the list, and this far offset needs to be larger than the offset of the A3 handover event, making it easier for the user terminal to camp on the in-building distribution cell.

[0149] In step S130, after determining the cell adjustment strategy, the electronic device may also execute the cell adjustment strategy.

[0150] Exemplarily, when the cell adjustment strategy is one of the first strategy, the second strategy, and the third strategy, execute the cell adjustment strategy to achieve cell reselection, and then achieve cell adjustment; when the cell adjustment strategy is the fourth strategy or the fifth strategy, execute the cell adjustment strategy to achieve cell handover, and then achieve cell adjustment.

[0151] To better understand the cell adjustment method provided in the embodiments of the present application, a specific implementation manner will be described below.

[0152] As Figure 2 shown, the method for cell reselection and handover in the floor edge scenario provided in the embodiments of the present application (i.e., the cell adjustment method) may include steps S210 to S240.

[0153] S210. Obtain user location and behavior data (i.e., obtain the target location data of the user terminal and user behavior data in the above step S110).

[0154] S220. Identify whether it is an edge user (i.e., determine whether the target user is an edge user in the above step S110).

[0155] S230. Judge the state of the user terminal.

[0156] S240. Adjust the cell reselection and handover strategies (i.e., determine the cell adjustment strategy in the above step S120).

[0157] More specifically, before step S210, there is also step one.

[0158] Step one. Neighboring cell search, obtain other cell broadcast information, and identify macro stations and in-building distribution signals.

[0159] After the user terminal camps on the current cell, as the user moves, the signal strength and quality of the primary serving cell (i.e., the current cell) and neighboring cells (i.e., neighboring cells) received by the user terminal will change continuously. At this time, the terminal will start to search and measure the signal strength of other surrounding neighboring cells so that it can camp on a cell with better signal at any time.

[0160] The cell broadcast information contains the type information of the cell (i.e., cell type), which can be a macro station or an in-building distribution system. When the user terminal performs neighbor cell search, it can read the broadcast information of each cell to determine the cell type.

[0161] If an in-building distribution system cell appears in the searched neighbor cells, go to Step 2.

[0162] Step 2: Identify edge users based on user behavior data and location information (i.e., target location data).

[0163] When the user terminal first detects an in-building distribution system signal (i.e., a neighbor cell of the in-building distribution system cell type), record the action time and trajectory of the user (i.e., the target user) under the in-building distribution system coverage area according to satellite positioning data, base station positioning data, and user behavior data, and determine whether the user is an edge user. Edge users are further divided into temporary edge users and resident edge users. User behavior data can be obtained through the acceleration sensor and three-axis gyroscope of the user terminal.

[0164] When the user first enters the coverage area of the in-building distribution system cell (i.e., a neighbor cell of the in-building distribution system cell type), the user terminal determines the action trajectory and time of the user according to the data of the acceleration sensor and three-axis gyroscope. Combining satellite positioning data and base station positioning data, identify whether the user is in the edge area of the in-building distribution system. Each building with in-building distribution system coverage has the longitude and latitude of the geometric center point of the building. When the user moves in the edge area of the in-building distribution system cell and the distance from the geometric center point of the building changes by no more than 5 meters, the user is determined to be a temporary edge user, and the IMEI number of the user terminal is added to the temporary edge user list. When the residence time of the user terminal in this range (i.e., the current residence duration) exceeds one hour, the user is classified as a resident edge user, and at the same time, the IMEI number of the user terminal is transferred to the resident edge user list and maintained for a long time. That is to say, a resident edge user needs to meet the condition that a temporary edge user stays in the edge area for more than the first preset value. After being identified as a resident edge user, the IMEI number of the user is deleted from the temporary edge user list and added to the resident edge user list and saved for a long time.

[0165] Exemplarily, a temporary edge user needs to meet the following conditions: Based on the user's behavior data, it is determined that the user has traveled a certain distance to this area and has not stayed in this area for more than the first preset value before. After being identified as a temporary edge user, the IMEI number of the user is added to the temporary edge user list. If the user leaves before the residence time in the edge area does not exceed the first preset value, it is deleted from the temporary edge user list and re-determined when entering next time.

[0166] Step 3: Implement corresponding reselection and handover criteria for users in the edge user list.

[0167] For users within the temporary edge user list, when performing cell reselection or handover, first ignore the macro station signals (i.e., neighboring cells with the cell type of macro station), and select among the in-building distribution (iD) cell signals (i.e., neighboring cells with the cell type of in-building distribution). When the signal strengths of all in-building distribution cell signals cannot meet the conditions (i.e., the preset conditions), the user terminal starts to consider camping on the macro station cell (i.e., neighboring cells with the cell type of macro station).

[0168] When the user terminal is in the idle state, the change of the user's location may cause the terminal to perform cell reselection.

[0169] 1) If multiple neighboring in-building distribution cells (i.e., neighboring cells with the cell type of in-building distribution) on the highest priority meet the conditions (i.e., the preset conditions), then select the optimal in-building distribution cell on the highest priority frequency. For equally prioritized frequency points (or same frequency), the R criterion for intra-frequency cell reselection is adopted.

[0170] 2) When all in-building distribution cells (i.e., neighboring cells with the cell type of in-building distribution) do not meet the conditions, that is, the S values of all measured in-building distribution cells are less than the preset threshold, then consider the macro station cell (i.e., neighboring cells with the cell type of macro station) together, and select the best cell on the highest priority frequency among all cells (i.e., multiple neighboring cells) for camping. The preset threshold should be less than the minimum received level set by the S criterion.

[0171] When the user (i.e., the target user) is in the connected state, the change of the user's location may cause the terminal to perform cell handover.

[0172] 1) If the user moves from the outdoor to the in-building distribution edge area, the user will be identified as a temporary edge user. When a handover event occurs, the base station assigns an entry offset to the users in the list (i.e., the temporary edge user list and the permanent edge user list). This entry offset should be smaller than the A3 handover event offset, making it easier for the user terminal to hand over to the in-building distribution cell.

[0173] 2) If the user moves from the in-building distribution edge area to the outdoor, when a handover event occurs, the base station assigns a departure offset to the users in the list. This departure offset should be larger than the A3 handover event offset, making it easier for the user terminal to camp on the in-building distribution cell.

[0174] It should be added that when the users in the permanent edge user list enter the in-building distribution edge area again for reselection or handover, directly perform reselection or handover according to the criteria in step three above.

[0175] In the embodiment of the present application, the user terminal can identify whether the user is at the floor edge (i.e., the in-building distribution edge area) through positioning (i.e., target positioning data) and user behavior (i.e., user behavior data). If it is identified that the user is at the floor edge, when the user terminal performs cell reselection and handover, it searches for neighboring cells (i.e., neighboring cell communities), obtains cell broadcast information, identifies the macro station and in-building distribution signals, and preferentially camps on the in-building distribution cell. Specifically, first, it searches for neighboring cells, obtains the broadcast information of other cells, identifies the macro station and in-building distribution signals, then the user terminal identifies the floor-edge user (i.e., the edge user), and then only considers camping on the in-building distribution cells. If the signal of the in-building distribution cell meets the conditions, it camps on the in-building distribution cell (i.e., the cell with the cell type of in-building distribution), and if it does not meet the conditions, it considers the macro station cell (i.e., the cell with the cell type of macro station).

[0176] Embodiment 2

[0177] As Figure 3 shown, the cell adjustment device provided in the embodiment of the present application can be applied to a user terminal, and includes a first acquisition module 310, a first determination module 320, and an execution module 330.

[0178] Among them, the first acquisition module 310 is configured to acquire a plurality of cell broadcast information corresponding one-to-one to a plurality of neighboring cell communities; the neighboring cell communities are cells other than the current cell and adjacent to the current cell; the current cell is the cell where the user terminal is currently camping; the cell broadcast information includes the cell type; the cell type includes in-building distribution or macro station;

[0180] The execution module 330 is connected to the first determination module 320, and is configured to execute the cell adjustment strategy.

[0181] According to the cell adjustment device provided by the embodiments of the present application, first obtain a plurality of cell broadcast information corresponding to a plurality of neighboring cells one by one, and then determine the cell adjustment strategy of the user terminal and execute the cell adjustment strategy when there is at least one neighboring cell with a cell type of in-building distribution and the target user holding the user terminal is an edge user. That is to say, in the embodiments of the present application, since the cell adjustment strategy includes the strategy that the residence priority of in-building distribution is higher than that of macro station, that is, the cell type of the target cell determined according to the cell adjustment strategy is more likely to be in-building distribution, the user terminal is resident in the target cell, so that the edge user preferentially resides in the neighboring cell with a cell type of in-building distribution. Since the usage perception of the edge user in the neighboring cell with a cell type of in-building distribution is stronger than that of the edge user in the neighboring cell with a cell type of macro station, therefore, compared with the prior art in which the user terminal is resident in the neighboring cell with a cell type of macro station, it can improve or solve the problem of poor usage perception of the floor edge user.

[0206] When there is only one target neighboring cell, determine the cell adjustment strategy for the user terminal as the first strategy; the first strategy includes determining the target neighboring cell as the target cell; the target neighboring cell includes a neighboring cell with a cell type of indoor distribution and satisfying a preset condition; the preset condition includes that the S value of the neighboring cell is greater than or equal to a preset threshold;
