Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a cell selection or reselection method, apparatus, and storage medium. Background Technology

[0002] 5G New Radio (NR) defines two frequency ranges (FR): FR1 and FR2. FR1 represents the low-frequency band, and FR2 represents the millimeter-wave high-frequency band. Cells within FR1 are called low-frequency cells, and cells within FR2 are called high-frequency cells.

[0003] High-frequency cells have ultra-large bandwidth, enabling them to provide higher transmission rates for user equipment (UE) and increase system capacity. However, due to the smaller coverage area of ​​high-frequency cells, high-speed mobile UEs may experience frequent cell reselection or handover within FR2 cells, thus affecting network performance.

[0004] Therefore, how a UE can select a suitable cell to camp on under different mobility states is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application relates to a cell selection or reselection method, apparatus, and storage medium, which allows UEs in different mobility states to camp on appropriate cells, avoiding frequent cell reselection or handover, thereby improving network performance.

[0006] In a first aspect, embodiments of this application provide a cell selection or reselection method, including:

[0007] Receive configuration information, which includes multiple cell information of a first cell, wherein the first cell is an FR2 cell, a cell at a specified frequency point, or a cell at a specified frequency band, and the multiple cell information corresponds to different mobility states;

[0008] Based on the current mobility status and the configuration information, cell selection or cell reselection is performed.

[0009] In the above method, the network device configures different cell information for UEs in different mobility states, so that UEs in different mobility states can camp on appropriate cells, avoiding frequent cell reselection or handover, thereby improving network performance.

[0025] Receive an RRC release message, the RRC release message including first information, the first information indicating that the first cell has the highest frequency priority.

[0026] In the above method, by setting the frequency priority of the first cell in the RRC release message, the UE can quickly establish a connection with the first cell after the connection is released, thereby providing more stable network services and optimizing the user experience.

[0034] Wherein, the frequency priority information indicates the frequency priority of the first cell when the UE is in the mobile state corresponding to the cell information, and the scaling parameter is used to adjust the cell reselection parameter and / or the frequency priority indicated by the frequency priority information.

[0071] Figure 1 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application. For example... Figure 1 As shown, this application scenario includes network device 101, network device 102, and UE103.

[0072] Network devices can provide communication coverage for a specific geographical area and can communicate with UEs located within that coverage area, which can also be called a cell. Figure 1 The diagram shows three cells, cell 1, cell 2, and cell 3, provided by network device 101 for communication coverage. Network device 102 provides three cells, cell 4, cell 5, and cell 6. Each cell can correspond to a frequency range. These six cells can correspond to the same frequency range or different frequency ranges; this embodiment does not limit this. The frequency range corresponding to a cell refers to the frequency range allocated to the cell by the network device (e.g., a base station controller), and the cell can broadcast or communicate within the allocated frequency range.

[0074] It should be understood that Figure 1 Two network devices and one UE are illustrated exemplarily, but this should not be construed as limiting the scope of this application. Optionally, the application scenario may include at least one network device, and the coverage area of ​​each network device may include other numbers of UEs, which is not limited in this embodiment.

[0075] The technical solutions provided in this application can be applied to a variety of systems. Applicable systems may include, but are not limited to: narrowband Internet of Things (NB-IoT), wideband code division multiple access (WCDMA), code division multiple access 2000 (CDMA2000), time division-synchronization code division multiple access (TDSCDMA), long term evolution (LTE), fifth-generation mobile communication systems or possible sixth-generation or seventh-generation mobile communication systems, vehicle-mounted short-range wireless communication systems, and future mobile communication systems.

[0076] This technical solution is also applicable to different network architectures, including but not limited to relay network architecture, dual-link architecture, and vehicle-to-everything (V2X) communication architecture.

[0077] The UE involved in the embodiments of this application can also be referred to as a terminal, including various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user equipment. A terminal can also be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, a terminal in a 5G network, or a terminal in a future evolved public land mobile network (PLMN), etc., and the embodiments of this application are not limited thereto.

[0078] The network devices involved in the embodiments of this application can be access network devices, including base stations, which may include multiple cells providing services to UEs. Depending on the specific application, a base station may also be called an access point, or a device in the access network that communicates with a wireless terminal through one or more sectors on the air interface, or other names. For example, the network devices involved in the embodiments of this application may be evolved network devices (eNB or e-NodeB) in LTE systems, 5G base stations (gNB) in 5G network architectures (next generation systems), or home evolved Node B (HeNB), relay nodes, femto, pico, network testing equipment, etc., and the embodiments of this application are not limited thereto. In some network structures, network devices may include centralized units (CU) and distributed units (DU), and CU and DU may also be geographically separated.

[0079] For ease of understanding, the relevant technologies involved in the embodiments of this application will be described below.

[0080] For connected UEs, due to their radio resource control (RRC) connection with the base station, the base station can determine whether the UE needs to switch to a new cell through measurement reporting and other methods. However, for disconnected UEs, since there is no RRC connection with the base station, the base station is unaware when the UE moves from one cell to another. Therefore, the rules for cell selection or cell reselection of the UE need to be defined through a protocol. The cell selection or cell reselection rules are explained in detail below.

[0081] When a UE selects a new public land mobile network (PLMN), cell selection is required. A suitable cell that is allowed to camp on can be selected using the S criterion; alternatively, in the event of cell rebuilding, cell selection can also be performed using the S criterion. The conditions for the S criterion are as follows:

[0082] Srxlex > 0, Squal > 0

[0083] Where Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Q offsettemp Squal = Qqualmeas –(Q qualmin +Q qualminoffset )-Q offsettemp .

[0084] The explanations of the parameters in the S criterion are shown in Table 1.

[0085] Table 1

[0086]

[0087]

[0088] After selecting a suitable cell for camping based on the S criterion, the UE may reselect if it discovers a better or more suitable cell through measurement. If the signal quality of the cell the UE is camping in is greater than a threshold, no intra-frequency or inter-frequency measurement will be initiated; or if no other frequency with higher priority is found, the UE does not need to initiate measurement. The measurement initiation conditions are as follows:

[0089] 1. If the measurement of the serving cell satisfies Srxlev>S IntraSearchP And Squal>S IntraSearchQ If the frequency is not specified, then no same-frequency measurement will be performed; otherwise, same-frequency measurement will be initiated. Wherein, S... IntraSearchP To trigger the received signal strength threshold for same-frequency measurements, S IntraSearchQ The received signal quality threshold for initiating in-frequency measurements.

[0090] 2. If no other frequency cell with higher frequency priority is found, inter-frequency and inter-system measurement will not be initiated.

[0091] 3. For cells with the same or lower priority but different frequencies and systems: If the current cell satisfies Srxlev>S nonIntraSearchP And Squal>S nonIntraSearchQ If the frequency and system are not specified, then inter-frequency and inter-system measurements will not be performed; otherwise, inter-frequency and inter-system measurements will be initiated. Wherein, S... nonIntraSearchP To trigger the received signal strength threshold for inter-frequency and inter-system measurements, S nonIntraSearchQ The received signal quality threshold is set to enable inter-frequency and inter-system measurements.

[0092] After the measurement is started, the cell reselection conditions are as follows:

[0093] 1. For cells with the same frequency priority or cells on the same frequency, if the UE camps on the current serving cell for more than 1 second, and the R value of the current serving cell is less than the R value of the target cell within the cell reselection time (Treselection) configured in the system message, cells can be sorted according to the R criterion. If rangeToBestCell is not configured, the cell with the highest reselection quality value R is selected as the target cell for reselection. If rangeToBestCell is configured, the UE can select the cell with the most beams above the threshold from the cells ranked by the highest rangeToBestCell according to the R criterion. If there are multiple cells with the same number of beams above the threshold, the cell with the highest ranking is selected for reselection. The threshold can be the absThreshSS-BlocksConsolidation threshold.

[0094] The R criterion is as follows:

[0095] R s =Q meas,s +Q hyst -Q offsettemp

[0096] R n =Q meas,n -Q offset -Q offsettemp

[0097] Among them, R s The reselection quality value for the service community; Q meas,s The received signal quality measurement value for the serving cell; Q hyst The cell reselection hysteresis value; Q offsettemp The definition is the same as that in the S criterion; R n Q represents the reselection quality value of adjacent cells. meas,n Q represents the received signal quality measurement value of the adjacent cell; offset This is the offset value between adjacent cells. For cells with the same frequency, if Q is configured... offsets,n Then Q offset For Q offsets,n If Q is not configured offsets,n Then Q offset The value is 0. For inter-frequency cells, if Q is configured... offsets,n Then Q offset =Q offsets,n +Q offsetfrequency If Q is not configured offsets,n Then Qoffset For Q offsetfrequency .

[0098] 2. For high-frequency priority cells, i.e., inter-frequency or inter-system cells with a higher frequency priority than the serving cell, if the cell has been camped on the current serving cell for more than 1 second, and the measurement result Squal > Thresh of the high-frequency priority cell... X,HighQ Or Srxlev>Thresh X,HighP If the number of cells exceeds the Treselection configured in the system message, then the cell can be reselected to the high-frequency priority cell. Among these, Thresh... X,HighQ or Thresh X,HighP These are all threshold values ​​configured by network devices through system messages.

[0099] 3. For cells with lower frequency priority than the current cell, i.e., inter-frequency cells or inter-system cells with lower frequency priority than the serving cell, if the cell has been camped in the current serving cell for more than 1 second, and the current serving cell satisfies Squal... <Thresh Serving,LowQ Furthermore, the measurement result for this low-frequency priority cell, Squal > Thresh. X,LowQ If the Treselection limit configured in the system message is exceeded, the cell can be reselected to the low-frequency priority cell. Alternatively, the currently serving cell meets the Srxlev requirement. <Thresh Serving,LowP Furthermore, the measurement results for this low-frequency priority cell show Srxlev > Thresh. X,LowP Furthermore, if the Treselection limit configured in the system message is exceeded, the cell can be reselected to that low-frequency priority cell. Among these, Thresh... Serving,LowQ or Thresh X,LowQ or Thresh Serving,LowP or Thresh X,LowP These are all threshold values ​​configured by network devices through system messages.

[0100] After the selected cell meets the requirements, the UE also needs to check whether the selected cell is a suitable cell. For example, is the cell prohibited or not allowed to access, or is the cell restricted to subscribed users only? If it is a suitable cell, the UE will reselect the cell to camp on.

[0101] Furthermore, the network configures different scaling factors for UEs in different mobility states. For example, in this application, the UE's mobility state is determined as follows: a network-configured duration T... CRmax Within, the number of cell reselections is less than N. CR_M If the duration T is within a certain range, then the UE's movement state is considered to be normal movement state; if the duration T is within a certain range...CRmax Within, the number of cell reselections is greater than or equal to N. CR_M And the number of cells is equal to or equal to N. CR_H If the duration T is within a certain range, then the UE's movement state is considered to be in a medium-movement state; if the duration T is within a certain range... CRmax Within, the number of cell reselections is greater than or equal to N. CR_H If so, the UE's mobility state is considered to be a high mobility state.

[0102] The scaling rules are as follows: UEs in normal mobility mode do not need to use a scaling factor; UEs in high mobility mode can use the sf-High parameter configured in the system message to scale the parameters, for example, the Q parameter configured in the network. hyst Adding sf-High yields the Q value suitable for UEs in high-speed movement. hyst Multiplying the network-configured Treselection by sf-High yields the cell reselection duration in high-speed mobility mode; for UEs in medium mobility mode, the parameter is scaled using the sf-Medium configured in the system message, for example, by scaling the network-configured Q... hyst Adding sf-Medium yields the Q value suitable for the UE in a medium-speed movement state. hyst Multiply the Treselection configured in the network by sf-Mediumh to obtain the cell reselection duration under medium-speed mobility.

[0103] For some special scenarios, such as multimedia broadcast service (MBS) broadcast services, if the relevant MBS broadcast service of the UE is being provided or can only be provided on a certain frequency cell, then the frequency will be given the highest priority when the UE is performing or preparing to perform the relevant service; conversely, if the cells on one or more frequency points cannot provide the UE with the MBS broadcast service that is being performed or that the UE is interested in performing, then the frequency will be given the lowest priority.

[0104] Currently, during measurement relaxation, the UE can first determine whether it is stationary. If stationary, the UE can appropriately relax its measurement requirements, meaning it can measure fewer neighboring cells to save power. The method the UE uses to determine stationary or low-mobility status is: within a specified time, if the UE's measurement results meet (Srxlev... Ref –Srxlev) SearchDeltaP If it is determined that it is a stationary UE or a low-mobility UE, then it is identified as such. Among them, Srxlev Ref The reference Srxlev value for the service cell.

[0105] ​This application provides a cell selection or reselection method. For FR2 cells, or cells at a specified frequency point, or cells in a specified frequency band, the network device can configure different cell information for UEs in different mobility states, so that UEs in different mobility states can camp on the appropriate cell, avoiding frequent cell reselection or handover, thereby improving network performance.

[0106] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or identical content will not be repeated in different embodiments.

[0107] Figure 2 This is a flowchart illustrating a cell selection or reselection method provided in an embodiment of this application. Figure 2 As shown, the method includes:

[0108] S201, The network device sends configuration information; correspondingly, the UE receives the configuration information. The configuration information includes information about multiple cells in the first cell, and the mobility states corresponding to these multiple cell information are different.

[0109] The first cell is an FR2 cell, or a cell with a specified frequency point, or a cell with a specified frequency band.

[0110] FR2 cells refer to cells within the FR2 range, that is, cells within the frequency range of 24250MHz to 52600MHz, which can also be called high-frequency cells.

[0111] The frequency of a cell with a specified frequency point can be located within any frequency range. For example, the frequency of a cell with a specified frequency point can be located within FR1 or FR2.

[0112] The frequency band of a cell in a specified frequency band can be located within any frequency range. For example, the frequency point of a cell in a specified frequency band can be located within FR1 or FR2.

[0113] The different mobility states corresponding to multiple cell information means that the network device configures different cell information for UEs with different mobility states.

[0114] Multiple cell information entries correspond to different mobility states. For example, if there are three cell information entries: cell 1, cell 2, and cell 3, cell 1 can correspond to mobility state 1, cell 2 to mobility state 2, and cell 3 to mobility state 3. That is, the network device can configure cell information 1 for mobility state 1, cell information 2 for mobility state 2, and cell information 3 for mobility state 3.

[0115] In another example, multiple cell information includes first cell information and second cell information. The first cell information is the cell information used by the UE in the first mobility state, and the second cell information is the cell information used by the UE in the second mobility state. The second mobility state is the mobility state that the UE has other than the first mobility state.

[0116] The first movement state can be any one or more of the following: stationary state, low movement state, medium movement state, or high movement state. When the first movement state is multiple of the following: stationary state, low movement state, medium movement state, or high movement state, it indicates that the first movement state is a combination of these multiple states.

[0117] For example, the first movement state is a stationary state, and the second movement state can be a low movement state, a medium movement state, or a high movement state. Another example: the first movement state is a high movement state, and the second movement state can be a stationary state, a low movement state, or a medium movement state. Yet another example: the first movement state is a combination of a stationary state and a low movement state, and the second movement state can be a medium movement state or a high movement state. Alternatively, the first movement state is a combination of a medium movement state and a high movement state, and the second movement state can be a stationary state or a low movement state.

[0118] In one possible implementation, the UE's moving speed in the first moving state may be lower than the UE's moving speed in the second moving state. For example, the first moving state is a combination of a stationary state and a low-movement state, and the second moving state is a medium-movement state or a high-movement state.

[0119] Network devices can send configuration information to the UE via system messages.

[0120] It should be noted that the network equipment can be the network equipment of the first cell or the network equipment of the adjacent cell of the first cell.

[0121] S202. The UE performs cell selection or cell reselection based on the current mobility status and configuration information.

[0122] Based on its current mobility status and configuration information, the UE can choose to camp on the first cell or on other cells.

[0123] When a UE selects the first cell to camp on, the priority of the first cell can be set to the highest.

[0124] exist Figure 2In the illustrated embodiment, the network device can configure different cell information for UEs in different mobility states, so that UEs in different mobility states can camp on appropriate cells, avoiding frequent cell reselection or handover, thereby improving network performance.

[0125] exist Figure 2 Based on the illustrated embodiment, the specific content of each cell's information will be described in detail below.

[0126] In one possible implementation, the cell information includes at least one of the following:

[0127] (1) Cell reselection parameters

[0128] Cell reselection parameters include parameters required for the UE to perform cell selection and / or parameters required for the UE to perform cell reselection.

[0129] Cell reselection parameters may include at least one of the following: offset value used in S criterion, threshold value used in S criterion, offset value used in R criterion, threshold value used in R criterion, first threshold value, second threshold value, and cell reselection duration (Treselection).

[0130] The offset value used in the S criterion can include Q. offsettemp Q rxlevminoffse Q qualminoffset The threshold values ​​used in the S criterion can include Q. rxlevmin Q qualmin The offset values ​​used in the R criterion include Q. offset Q hyst Q offsettemp The threshold values ​​used in the R criterion can include the SSB merging threshold.

[0131] The first threshold value is the threshold value used by the first cell in the case of reselection to the first cell during frequency priority selection. For example, the first threshold value may include Thresh. X,HighQ Thresh X,HighP Thresh X,LowQ Thresh X,LowP .

[0132] The second threshold is the threshold value used by the second cell when reselecting to the first cell in frequency priority selection. The second cell is the cell currently serving the UE. For example, the second threshold value may include Thresh. Serving,LowQ Thresh Serving,LowP The second community can also be called a service community.

[0133] It should be noted that the cell reselection parameters may include not only the parameters mentioned above, but also other offset values, other threshold values, or other durations used in the cell reselection process. This application does not impose any limitations on this.

[0134] (2) Frequency priority information

[0135] Frequency priority information can indicate the frequency priority of the first cell when the UE is in the mobile state corresponding to the cell information.

[0136] Frequency priority information can directly indicate the frequency priority of the first cell, or it can indirectly indicate the frequency priority of the first cell.

[0137] For example, the network device configures cell information 1 for mobile state 1 and cell information 2 for mobile state 2. The frequency priority information in cell information 1 indicates that the frequency priority of the first cell is frequency priority 1; the frequency priority information in cell information 2 indicates that the frequency priority of the first cell is frequency priority 2. Within the first cell, if the UE is in mobile state 1, the frequency priority of the first cell used by the UE for cell selection or cell reselection is frequency priority 1; if the UE is in mobile state 2, the frequency priority of the first cell used by the UE for cell selection or cell reselection is frequency priority 2.

[0138] In another example, the network device configures cell information 1 and cell information 2 for mobile state 1. Cell information 1 indicates that the frequency priority of the first cell is higher than that of the FR1 cell; cell information 2 indicates that the frequency priority of the first cell is lower than that of the FR1 cell. Within the first cell, if the UE is in mobile state 1, the frequency priority of the first cell used by the UE for cell selection or cell reselection is higher than that of the FR1 cell; if the UE is in mobile state 2, the frequency priority of the first cell used by the UE for cell selection or cell reselection is lower than that of the FR1 cell.

[0139] (3) Scaling parameters

[0140] Scaling parameters can be used to adjust the frequency priority indicated by cell reselection parameters and / or frequency priority information.

[0141] The scaling parameter can be a scaling value and / or a scaling ratio.

[0142] It should be noted that network devices can be configured with a scaling parameter for each mobility state, or for a subset of mobility states.

[0143] The parameters included in the cell information corresponding to different mobility states can be the same or different.

[0144] The following section details multiple cell information, including first cell information and second cell information, using this example. First cell information refers to the cell information used by the UE in its first mobile state, and second cell information refers to the cell information used by the UE in its second mobile state.

[0145] Example 1

[0146] The first cell information includes cell reselection parameter 1, and the second cell information includes cell reselection parameter 2. When the UE is in the first moving state, the UE uses cell reselection parameter 1 to perform cell selection or cell reselection. When the UE is in the second moving state, the UE uses cell reselection parameter 2 to perform cell selection or cell reselection.

[0147] If the UE's moving speed in the first moving state is lower than its moving speed in the second moving state, for the same offset value, the offset value in cell reselection parameter 1 is greater than the offset value in cell reselection parameter 2; for the same threshold value, the threshold value in cell reselection parameter 1 is less than the threshold value in cell reselection parameter 2; and the cell reselection duration in cell reselection parameter 1 is less than the cell reselection duration in cell reselection parameter 2. Due to the differences in the values ​​of the cell reselection parameters, the UE is more likely to camp on the first cell when in the first moving state.

[0148] Example 2

[0149] The first cell information includes frequency priority information 1, and the second cell information includes frequency priority information 2. When the UE is in a first mobile state, the UE uses the frequency priority indicated by frequency priority information 1 to perform cell selection or cell reselection. When the UE is in a second mobile state, the UE uses the frequency priority indicated by frequency priority information 2 to perform cell selection or cell reselection.

[0150] Assuming frequency priorities range from 0 to 7, where 0 is the lowest frequency priority, frequency priority information 1 indicates that the first cell has a priority of 7, and frequency priority information 2 indicates that the first cell has a priority of 5. The UE is in the first mobile state and is more likely to camp on the first cell.

[0151] Example 3

[0152] The first cell information includes cell reselection parameter 1 and frequency priority information 1, and the second cell information includes cell reselection parameter 2 and frequency priority information 2. When the UE is in a first mobile state, the UE uses the frequency priority indicated by cell reselection parameter 1 and frequency priority information 1 to perform cell selection or cell reselection. When the UE is in a second mobile state, the UE uses the frequency priority indicated by cell reselection parameter 2 and frequency priority information 2 to perform cell selection or cell reselection.

[0153] Example 4

[0154] The first cell information includes scaling parameters, and the second cell information includes cell reselection parameter 1. When the UE is in the second mobility state, the UE uses cell reselection parameter 1 to perform cell selection or cell reselection. When the UE is in the first mobility state, the UE processes cell reselection parameter 1 using scaling parameters to obtain cell reselection parameter 2, and uses cell reselection parameter 2 to perform cell selection or cell reselection.

[0155] When the scaling parameter is a scaling ratio R (0 < R < 1), for any offset value, such as Q offsettemp Q in cell reselection parameter 2 offsettemp =Q in cell reselection parameter 1 offsettemp ÷R; For any threshold value, such as the first threshold value, the first threshold value in cell reselection parameter 2 = the first threshold value in cell reselection parameter 1 * R; the cell reselection duration in cell reselection parameter 2 = the cell reselection duration in cell reselection parameter 1 * R.

[0156] When the scaling parameter is the scaling value X, for any offset value, such as Q offsettemp Q in cell reselection parameter 2 offsettemp =Q in cell reselection parameter 1 offsettemp +X; For any threshold value, such as the first threshold value, the first threshold value in cell reselection parameter 2 = the first threshold value in cell reselection parameter 1 - X; the cell reselection duration in cell reselection parameter 2 = the cell reselection duration in cell reselection parameter 1 - X.

[0157] Example 5

[0158] The first cell information includes scaling parameters, and the second cell information includes frequency priority information. When the UE is in the second mobility state, the UE uses frequency priority 1 indicated by the frequency priority information to perform cell selection or cell reselection. When the UE is in the first mobility state, the UE processes frequency priority 1 using scaling parameters to obtain frequency priority 2, and uses frequency priority 2 to perform cell selection or cell reselection.

[0159] When the scaling parameter is the scaling ratio R (0 < R < 1), frequency priority 2 = frequency priority 1 ÷ R. When the scaling parameter is the scaling value X, frequency priority 2 = frequency priority 1 + X.

[0160] Example 6

[0161] The first cell information includes scaling parameters, and the second cell information includes cell reselection parameter 1 and frequency priority information. When the UE is in the second mobility state, the UE uses frequency priority 1 and cell reselection parameter 1 indicated by the frequency priority information to perform cell selection or cell reselection. When the UE is in the first mobility state, the UE uses the scaling parameters to process frequency priority 1 and cell reselection parameter 1 respectively to obtain frequency priority 2 and cell reselection parameter 2, and uses frequency priority 2 and cell reselection parameter 2 to perform cell selection or cell reselection.

[0162] Example 7

[0163] The first cell information includes cell reselection parameter 1 and scaling parameter 1, and the second cell information includes cell reselection parameter 2 and scaling parameter 2. When the UE is in a first moving state, the UE processes cell reselection parameter 1 using scaling parameter 1 to obtain cell reselection parameter 1', and uses cell reselection parameter 1' to perform cell selection or cell reselection. When the UE is in a second moving state, the UE processes cell reselection parameter 2 using scaling parameter 2 to obtain cell reselection parameter 2', and uses cell reselection parameter 2' to perform cell selection or cell reselection.

[0164] Example 8

[0165] The first cell information includes frequency priority information 1 and scaling parameter 1, and the second cell information includes frequency priority information 2. When the UE is in the first mobility state, the UE uses scaling parameter 1 to process the frequency priority indicated by frequency priority information 1 to obtain frequency priority 1, and uses frequency priority 1 for cell selection or cell reselection. When the UE is in the second mobility state, the UE uses the frequency priority indicated by frequency priority information 2 for cell selection or cell reselection.

[0166] Example 9

[0167] The first cell information includes cell reselection parameter 1, frequency priority information 1, and scaling parameter 1. The second cell information includes cell reselection parameter 2, frequency priority information 2, and scaling parameter 2. When the UE is in a first mobile state, the UE uses scaling parameter 1 to process the frequency priorities indicated by cell reselection parameter 1 and frequency priority information 1, respectively, to obtain cell reselection parameter 1' and frequency priority 1. The UE then uses cell reselection parameter 1' and frequency priority 1 to perform cell selection or cell reselection. When the UE is in a second mobile state, the UE uses scaling parameter 2 to process the frequency priorities indicated by cell reselection parameter 2 and frequency priority information 2, respectively, to obtain cell reselection parameter 2' and frequency priority 2. The UE then uses cell reselection parameter 2' and frequency priority 2 to perform cell selection or cell reselection.

[0168] Based on the above, the following details how the UE determines its current mobility status.

[0169] In one possible implementation, if the difference between the maximum and minimum measured signal strength values ​​within a first time period is less than or equal to a third threshold value, the current mobility state is determined to be a first mobility state. Here, the start time of the first time period is the measurement start time, the duration of the first time period is predefined or configured by the network device, and the third threshold value is predefined or configured by the network device. Subsequently, cell selection or cell reselection can be performed using the cell information corresponding to the first mobility state.

[0170] Figure 3 This is a flowchart illustrating another cell selection or reselection method provided in an embodiment of this application.

[0171] like Figure 3 As shown, the method includes:

[0172] S301. The network device sends an RRC release message, and the corresponding UE receives the RRC release message. The RRC release message includes first information, which indicates that the first cell has the highest frequency priority.

[0173] For a description of the first community, please refer to the corresponding description in S201, which will not be repeated here.

[0174] In one possible implementation, the RRC release message may further include usage conditions and / or time information for the first information, wherein the time information indicates the usage period of the first information, and the usage conditions are used to determine the UE's mobility state, which is either a first mobility state or a second mobility state. For a description of the first and second mobility states, please refer to the description corresponding to S201.

[0175] Network devices can define a timer to indicate the period of use of the first information. When the timer expires, the UE can perform cell selection or cell reselection based on multiple cell information.

[0176] The conditions for use are: within the first time period, the difference between the maximum and minimum values ​​of the measured signal strength of the UE is less than or equal to the third threshold value.

[0177] S302, the network device sends configuration information; correspondingly, the UE receives the configuration information. The configuration information includes information about multiple cells in the first cell, and the mobility states corresponding to these multiple cell information are different.

[0178] S303: The UE performs cell selection or cell reselection based on the current mobility status and configuration information.

[0179] The execution process of S302 to S303 can be found in the execution process of S201 to S202, and will not be repeated here.

[0180] It should be noted that the network device that sends configuration information to the UE and the network device that sends RRC release message to the UE can be the same network device or different network devices.

[0181] The cell in which the UE receives the configuration information is different from the cell in which the UE receives the RRC release message. These two cells can belong to the same network device or different network devices. The UE uses the received configuration information for cell selection or cell reselection, instead of using the first information received through the RRC release message.

[0182] The UE can use a timer to record the usage period of the first information. After the timer expires, the UE can perform cell selection or cell reselection based on multiple cell information. The UE can also perform cell selection or cell reselection based on multiple cell information after a cell reselection occurs (i.e., after leaving the cell that received the RRC release message).

[0183] exist Figure 3 In the illustrated embodiment, based on the various parameters configured in the network device, the UE in the first mobile state is more likely to camp in the first cell, thereby achieving network load balancing and higher capacity.

[0184] The above describes in detail how to select or reselect a cell based on multiple cell information. The following describes in detail how to select or reselect a cell when multiple cell information and service-related residency information coexist.

[0185] Service-related camping information can refer to the following: When a UE has subscribed to a multimedia broadcast multicast service (MBMS) or a slicing service, or if the UE is interested in certain services, it will prioritize camping on cells that support MBMS, slicing services, or other services of interest. If cell information based on mobility state conflicts with service-related camping information, the UE can select a cell to camp on based on its own implementation; or select a cell to camp on based on its subscription information; or select a cell to camp on based on whether the UE is currently initiating or preparing to initiate MBMS, slicing services, or other services of interest. If the UE is currently initiating or preparing to initiate MBMS, slicing services, or other services of interest, it can choose to camp on a cell that supports MBMS, slicing services, or other services of interest. If the UE does not have any relevant services, it can select a cell to camp on based on the cell information.
