[0150] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other reselection prioritization methods, and next-generation systems extended from them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0151] In some implementations, the present disclosure relates to cell selection or cell reselection techniques, which are described below.

[0152] Optionally, when the terminal is in idle or inactive mode, it will select a cell to camp on. When the terminal needs to enter connected mode, it will initiate access (RRC (Radio Resource Control) establishment or recovery process) in the camped cell. Therefore, in order to balance the random access load among different frequency points, it is necessary to distribute the terminal's cell selection as evenly as possible, which is one of the main objectives of non-connectivity mobility management. Simultaneously, to ensure better performance for the terminal in the serving cell, the terminal needs to select a cell with superior signal quality when choosing a cell to camp on.

[0153] For example, once the terminal has finished residing, the following operations can be performed:

[0154] ① Obtain system information (relevant information on residence, access and reselection, location area information, etc.);

[0155] ② Obtain paging messages;

[0156] ③ Initiate the connection establishment / recovery process.

[0157] In order to perform cell selection / cell reselection, the terminal needs to perform cell measurements. The NR system supports multi-beam operation; in multi-beam measurements, the terminal selects a cell by measuring the quality of multiple beam signals. During cell reselection, to measure cell signal quality, the base station needs to configure cell parameters, such as the maximum number of usable beams (nrofSS - Blocks ToAverage) and threshold values ​​(absThreshSS - Consolidation). Cell signal quality is measured based on the synchronization signal / broadcast physical channel block (SS / PBCH block, SSB). The NR system uses beam scanning to transmit SSB signals; therefore, the terminal may hear the results of measurements from different beams within the same cell. The terminal obtains the cell signal quality as follows.

[0158] ①When the measurement quality of all beams in the measured cell is lower than the threshold value, the signal quality of the cell is the highest value of the signal quality among the measured beams.

[0159] ② Otherwise, the signal quality of the cell is obtained by linearly averaging the measured quality values ​​of the n beams with the highest signal quality above the threshold, where the number of beams n is at most the value configured by nrofSS-BlocksToAverage.

[0160] Optionally, if the terminal performs cell selection, cell selection generally occurs after PLMN selection. Its purpose is to enable the terminal to select a cell with satisfactory signal quality under the selected PLMN as soon as possible for camping.

[0161] The cell selection criterion S is satisfied when the following conditions are met:

[0162] Srxlev>0AND Squal>

[0163] 0

[0164] where:

[0165] Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -

[0166] Qoffset temp

[0167] Squal = Q qualmeas –(Q qualmin +Q qualminoffset -Qoffset temp

[0168] Optionally, when the terminal is in an idle or inactive state, continuous cell reselection is required to allow it to camp on a higher-priority / better-signal-quality cell. The network can control terminal camping by setting priorities for different frequency points. Simultaneously, the terminal will select the cell with the best signal quality on a given frequency point to provide better service. Through these steps, mobility management for non-connected terminals is achieved.

[0169] Cell reselection can be divided into intra-frequency cell reselection and inter-frequency cell reselection. Intra-frequency cell reselection mainly solves the problem of wireless coverage, while inter-frequency cell reselection can be used to solve both the problem of wireless coverage and the problem of load balancing.

[0170] 1) Cell reselection on the same frequency, based on the R criterion, the specific process is as follows:

[0171] ① By comparing the parameters S of the serving cell rxlev and S qual (The calculation method for the S-value is the same as that used during cell selection) and the parameter S in the system broadcast. intrasearchP and S intrasearchQ Decide whether to initiate same-frequency measurement: if S rxlev >S intrasearchP And S qual >S intrasearchQ If so, the terminal can choose not to perform the same-frequency measurement; otherwise, the terminal needs to perform the same-frequency measurement.

[0172] ② Sort the candidate cells according to their quality using the R criterion and select the optimal cell.

[0173] ③ Determine whether the optimal cell is a suitable cell based on the suitable cell criterion.

[0174] The cell-ranking criterion R s for serving cell and R n for neighboring cells is defined by:

[0175] R s =Q meas,s +Q hyst -Qoffset temp

[0176] R n =Q meas,n -Qoffset-Qoffset temp

[0177] where:

[0178] 2) Inter-frequency cell reselection

[0179] During inter-frequency cell reselection, the network can achieve load balancing across different frequency points by setting appropriate priority parameters. The steps for inter-frequency cell reselection are as follows.

[0180] (a) Measurement

[0181] For frequencies whose priority is higher than the current frequency as indicated by the system information, the terminal should always perform measurements on them. For frequencies whose priority is equal to or lower than the current frequency as indicated by the system information, the terminal's measurement criteria are as follows.

[0182] • If the S serving the community rxlev >S intrasearchP And S qual >S intrasearchQ The terminal can choose not to perform the same-frequency measurement;

[0183] • If the S serving the community rxlev >S nonintrasearchP And S qual >S nonintrasearchQ The terminal can choose not to perform inter-frequency or inter-RAT (Radio Access Technology) measurements;

[0184] Otherwise, the terminal needs to perform a measurement.

[0185] (b) Priority handling

[0186] The terminal can obtain frequency priority information (common priority) through broadcast messages, or through RRC release messages (private priority), or inherit it from other RATs when performing inter-RAT cell (re)selection. If a private priority is provided, the terminal will ignore all common priorities. If the system information does not provide priority information for the terminal's currently camped cell, the terminal will set the priority of the frequency point containing that cell to the lowest. The terminal will only perform cell reselection among frequencies that appear in the system information and have provided priorities, according to a priority strategy (preferably selecting frequencies with higher priority).

[0187] The terminal will delete the dedicated priority if the following occurs:

[0188] • A state transition has occurred at the terminal;

[0189] • The dedicated priority has expired (the preset time has been exceeded);

[0190] • NAS (Network Attached Storage) requires the selection of PLMN (Public Land Mobile Network).

[0191] (c) Cell reselection criteria

[0192] ① Cell reselection for high-priority frequencies.

[0193] If the terminal has been stationary in the current cell for more than 1 second, the process of cell reselection to a higher priority frequency cell will be carried out according to the following criteria.

[0194] • If the system broadcasts the parameter threshServingLowQ, high-priority frequency cells need to meet S qual Thresh X,HighQ And the duration exceeds Treselection RAT Only then can a neighborhood re-selection be carried out.

[0195] Otherwise, high-priority frequency cells need to meet S rxlev Thresh X,HighP And the duration exceeds Treselection RAT Only then can a neighborhood re-selection be carried out.

[0196] ② Cell reselection for the same priority frequency.

[0197] Cell reselection for NR frequencies with the same priority will be performed according to the R criterion based on sorting for the same-frequency reselection as described above.

[0198] ③ Cell reselection for low-priority frequencies.

[0199] If the terminal has stayed in the current cell for more than 1 s, the process of cell reselection to a low-priority frequency cell will be carried out according to the following criteria.

[0200] · If the parameter threshServingLowQ is broadcast in the system information, the serving cell needs to satisfy S qual < ThreshServing,LowQ, and the Srxlev of the low-priority frequency cell qual > Thresh X,LowP and the duration exceeds Treselection RAT before cell reselection can be performed.

[0201] · Otherwise, the serving cell needs to satisfy S rxlev < ThreshServing,LowP, and the Srxlev of the low-priority frequency cell > Thresh X,LowP and the duration exceeds Treselection RAT before cell reselection can be performed.

[0202] If multiple adjacent cells with the highest priority meet the criteria, the optimal cell with the highest priority frequency is selected. The object of inter-frequency cell reselection can be a cell in the neighbor cell list, a cell detected during the cell reselection process, or a frequency point of NR inter-frequency or different RATs. Currently, NR only supports inter-RAT cell reselection with E-UTRAN. If the terminal speed detection result shows that the terminal is in a non-normal mobile state, the scaled parameter Treselection should be used in reselection. RAT .

[0203] 3) Parameter scaling based on the terminal's moving speed

[0204] The moving speed of the terminal is divided into normal, medium, and high speeds. Different moving speeds are determined based on the number of cell reselections that the terminal has undergone within a certain period of time. If it is determined that the terminal is in a medium or high-speed moving state, the parameters Treselection and Qhyst need to be scaled to adapt to the terminal's state for reasonable cell reselection. The relevant parameters for speed judgment and scaling criteria are provided by the system information.

[0205] Figure 2 is an interaction schematic diagram of the reselection priority determination method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a reselection priority determination method, and the above method includes:

[0206] Step S2101: The network device sends the first configuration information to the terminal.

[0207] In some embodiments, the terminal receives first configuration information sent by the network device. It should be noted that the network device may also send the first configuration information without specifying an object; for example, the network device may send the first configuration information in a general way. Correspondingly, the terminal receives the first configuration information. Optionally, the network device may send the first configuration information via broadcast.

[0208] In some embodiments, the first configuration information is used to indicate whether the terminal is allowed to determine the reselection priority based on the terminal's mobility information. Alternatively, the first configuration information may also be used to indicate whether the terminal needs to determine the reselection priority based on mobility information. Alternatively, the first configuration information may also be used to indicate whether the terminal can re-determine the reselection priority.

[0209] In some embodiments, the cell reselection priority is related to the priority of the frequency used for cell reselection. Alternatively, it can be understood that the cell reselection priority is related to the absolute priority of the frequency used for cell reselection. Or, it can be understood that the cell reselection priority is associated with the frequency used for cell reselection.

[0210] Optionally, the reselection priority corresponds to one or more frequencies. For example, the reselection priority corresponds to one frequency. Alternatively, the reselection priority corresponds to multiple frequencies, which is not limited in this embodiment. Wherein, if the reselection priority corresponds to multiple frequencies, it means that the reselection priorities of multiple frequencies are the same. For example, frequencies 1, 2, and 3 all correspond to reselection priority A.

[0211] In some embodiments, the first configuration information includes at least one of the following:

[0212] (1) First information, the first information is used to indicate that the terminal camped in the first cell is allowed to determine the reselection priority based on the terminal's mobility information, and the first information is sent by the first cell.

[0213] In this embodiment of the disclosure, if a terminal in the first cell receives the first information, it is determined that all terminals in the first cell are allowed to determine the reselection priority based on the terminal's mobility information.

[0214] In some embodiments, the name of the first information is not limited in this disclosure. It may be, for example, public information or public indication information. Optionally, the first information may be SIB1 (System Information Block), SIB2, SIB4, SIB5, or other information.

[0215] It should be noted that this first information can be specific to different frequencies; that is, one or more frequencies may correspond to one or more pieces of first information. For example, one frequency may correspond to one piece of first information, or multiple frequencies may correspond to one piece of first information.

[0216] (2) Second information, which is used to indicate that the terminal corresponding to the second information is allowed to determine the reselection priority based on the terminal's mobility information.

[0217] In this embodiment of the disclosure, if the terminal receives the second information, it is determined that the terminal is allowed to determine the reselection priority based on the terminal's mobility information.

[0218] Optionally, the name of the first information is not limited in this embodiment. It may be, for example, dedicated information or dedicated instruction information. Optionally, the first information may be RRC release information or other information.

[0219] Optionally, the second information can be specific to different frequencies, meaning that one or more frequencies correspond to one or more pieces of second information. For example, one frequency may correspond to one piece of second information, or multiple frequencies may correspond to one piece of second information.

[0220] In some embodiments, the first configuration information includes first information and second information, and there are different ways to select the information to use.

[0221] Optionally, the terminal ignores the first information and uses the received second information as the standard.

[0222] Optionally, the terminal ignores the second information and takes the first information received as the standard.

[0223] Optionally, the terminal determines whether it is permitted to determine a reselection priority based on its mobility information based on the first information and the second information. For example, if both the first and second information indicate that the terminal is permitted to determine a reselection priority based on its mobility information, then the terminal is permitted to determine a reselection priority based on its mobility information. Alternatively, if either the first or second information indicates that the terminal is permitted to determine a reselection priority based on its mobility information, then the terminal is permitted to determine a reselection priority based on its mobility information. Furthermore, if at least one of the first and second information indicates that the terminal is not permitted to determine a reselection priority based on its mobility information, then the terminal is not permitted to determine a reselection priority based on its mobility information.

[0224] It should be noted that step S2101 above is an optional solution. Step S2101 can also be omitted, and the terminal can determine whether to determine the reselection priority based on the terminal's mobility information according to the communication protocol.

[0225] In step S2102, the network device sends the second configuration information to the terminal.

[0226] In some embodiments, the terminal receives second configuration information sent by the network device. It should be noted that the network device may also send the second configuration information without specifying an object; for example, the network device may send the second configuration information in a general way. Correspondingly, the terminal receives the second configuration information. Optionally, the network device may send the second configuration information via broadcast.

[0227] In some embodiments, the second configuration information is used to configure the correspondence between mobility information and priority. Alternatively, it can be understood as the second configuration information being used to configure the matching relationship between mobility information and priority. Or, it can be understood as the second configuration information being used to configure the mapping relationship between mobility information and priority.

[0228] Optionally, the correspondence between mobility information and priority can be configured through a table information table or through other means.

[0229] In some embodiments, the second configuration information includes at least one of the following:

[0230] (1) Mobility information includes low mobility state, and the correspondence between mobility information and priority includes the correspondence between low mobility state and priority.

[0231] Here, "low mobility state" refers to a state where the terminal is moving at a low speed. Optionally, "low mobility state" refers to a state where the number of reselections is less than a first threshold. Here, the number of reselections refers to the number of reselections within a first time period. Alternatively, "low mobility state" refers to a state where the average mobility speed is less than a certain speed. Here, the average mobility speed refers to the average mobility speed within a second time period.

[0232] In this embodiment of the disclosure, low mobility states correspond to priorities. For example, low mobility state corresponds to priority 1. Or, low mobility state corresponds to priority 2. Or, other correspondences may exist, which are not limited in this embodiment of the disclosure.

[0233] In some embodiments, the low mobility state includes the stationary state. That is, the stationary state and the low mobility state have the same priority.

[0234] It should be noted that the embodiments disclosed herein are illustrated using a low-mobility state as an example. In another embodiment, the mobility information can also be in a fixed state. A fixed state refers to a state in which the terminal is stationary.

[0235] (2) Mobility information includes multiple mobility states, and the correspondence between mobility information and priority includes the correspondence between each mobility state and priority.

[0236] For example, the movement states include fixed state, low movement state, normal movement state, medium movement state, and high movement state. The correspondence between each movement state and priority is shown in Table 1.

[0237] Table 1

[0238] Alternatively, the above correspondence can also be shown in Table 2, where the low-movement state, the fixed state, and the normal-movement state correspond to the same priority.

[0239] Table 2

[0240] It should be noted that the above embodiments are used as examples to illustrate the correspondence between movement state and priority. This disclosure does not limit the correspondence between movement state and priority, and other correspondences are also possible.

[0241] (3) Mobility information includes speed range, and the correspondence between mobility information and priority includes the correspondence between speed range and priority.

[0242] For example, if the speed range includes speed range 1, speed range 2 and speed range 3, then the correspondence between speed range and priority is shown in Table 3.

[0243] Table 3

[0244] It should be noted that the correspondence configured in the second configuration information corresponds to one or more frequencies. That is, the second configuration information can correspond to one frequency or multiple frequencies. In some embodiments, when configuring the second configuration information, one or more frequencies corresponding to the second configuration information are also set, thereby determining which frequencies the second configuration information corresponds to.

[0245] Optionally, if the correspondence configured in the second configuration information corresponds to a frequency, and the second configuration information is used to configure the correspondence between low mobility state and priority, then when the terminal is in low mobility state, the reselection priority corresponding to that frequency is the priority corresponding to low mobility state in the correspondence configured in the second configuration information.

[0246] Optionally, if the correspondence configured in the second configuration information corresponds to a frequency, and the second configuration information is used to configure the correspondence between each mobile state and priority among multiple mobile states, then the terminal determines the reselection priority based on the priority corresponding to its own mobile state at that frequency.

[0247] It should be noted that if the correspondence configured in the second configuration information corresponds to a frequency, it can also be understood that the terminal configures the correspondence in a Per Frequency configuration manner.

[0248] Optionally, if the correspondence configured in the second configuration information corresponds to multiple frequencies, and the second configuration information is used to configure the correspondence between low mobility state and priority, then when the terminal is in low mobility state, the reselection priority corresponding to the multiple frequencies is the priority corresponding to low mobility state in the correspondence configured in the second configuration information.

[0249] Optionally, if the correspondence configured by the second configuration information corresponds to multiple frequencies, and the second configuration information is used to configure the correspondence between each mobile state and priority in multiple mobile states, then the terminal determines the reselection priority based on the priority corresponding to its own mobile state in multiple frequencies.

[0250] Multiple frequencies can also be referred to as a frequency group or a set of frequencies. In other words, the correspondence configured in the second configuration information corresponds to a set of frequencies.

[0251] It should be noted that if the correspondence configured in the second configuration information corresponds to multiple frequencies, it can also be understood that the terminal configures the correspondence in a Per Frequency group configuration manner.

[0252] Another point to note is that step S2102 is an optional solution. Step S2102 can also be omitted, and the terminal can determine the corresponding relationship based on the communication protocol or pre-configuration.

[0253] Another point to note is that the first configuration information in step S2101 and the second configuration information in step S2102 can be the same configuration information or different configuration information. This embodiment of the disclosure does not limit this.

[0254] Another point to note is that the second configuration information in step S2102 can be used to implement the function of the first configuration information in step S2101. Optionally, the second configuration information can also be used to indicate whether the terminal is allowed to determine the reselection priority based on the terminal's mobility information. For example, the second configuration information includes the first information and / or the second information in the above embodiments, thereby indicating whether the corresponding terminal is allowed to determine the reselection priority based on the terminal's mobility information.

[0255] In step S2103, the terminal determines the reselection priority based on the terminal's mobility information.

[0256] In this embodiment of the disclosure, the terminal can acquire mobility information and then determine the corresponding reselection priority based on the mobility information. Optionally, the mobility information includes mobility status or mobility speed, and the terminal can determine the reselection priority based on the mobility status or mobility speed.

[0257] In some embodiments, the terminal determines the reselection priority based on the priority corresponding to the mobility information. There is a correspondence between mobility information and priority, therefore the reselection priority can be determined based on this correspondence and the mobility information.

[0258] Optionally, the original priority of the frequency for cell reselection by the terminal includes a first priority and a second priority, where the second priority is a sub-priority of the first priority. Therefore, determining the reselection priority based on the priority corresponding to the mobility information includes at least one of the following:

[0259] (1) Replace the original priority of the frequency for cell reselection by the terminal with the priority corresponding to the mobile information, and determine the priority corresponding to the mobile information as the reselection priority.

[0260] In some embodiments, the terminal replaces the original priority of the frequency used for cell reselection with all priorities corresponding to the mobile information.

[0261] For example, if the terminal's original priority is first priority A and second priority B, and the priority corresponding to the mobility information is priority C, then the priority of the frequency for the terminal to perform cell reselection is determined to be priority C. As another example, if the terminal's original priority is first priority A and second priority B, and the priority corresponding to the mobility information is first priority C and second priority D, then the priority of the frequency for the terminal to perform cell reselection is determined to be first priority C and second priority D.

[0262] (2) Replace the first priority of the frequency for cell reselection by the terminal with the priority corresponding to the mobile information, and determine the priority corresponding to the mobile information and the second priority as the reselection priority.

[0263] In some embodiments, if the priority corresponding to the mobility information only includes the first priority, then the first priority corresponding to the mobility information replaces the first priority of the original priority, and then the replaced first priority and the second priority are determined as the reselection priority.

[0264] For example, if the original priority of the terminal is first priority A and second priority B, and the priority corresponding to the mobile information is first priority C, then the priority of the frequency for the terminal to perform cell reselection is determined to be first priority C and second priority B.

[0265] It should be noted that the above embodiments are illustrated using the example of mobile information corresponding to priorities. In another embodiment, there is a situation where mobile information does not correspond to priorities.

[0266] In some embodiments, if the mobile information does not correspond to a priority, the terminal determines the reselected priority to be the original priority. Alternatively, if the mobile information does not correspond to a priority, the reselected priority is determined to be the lowest priority.

[0267] Alternatively, the lack of a corresponding priority for mobile information can also be understood as the network device failing to configure the correspondence between mobile information and priority for the terminal through configuration information.

[0268] It should be noted that if the mobile information does not have a corresponding priority and the terminal has not been configured with the original priority, then the reselected priority will be the lowest priority.

[0269] In some embodiments, the terminal receives fourth configuration information sent by the network device, which is used to configure the original priority of one or more frequencies. The original priority refers to the frequency priority configured by the terminal before executing step S2103.

[0270] It should be noted that mobility information includes mobility status, so the terminal can obtain the terminal's mobility status and determine the reselection priority based on the terminal's mobility status.

[0271] In some embodiments, the terminal determines the mobility state based on the number of reselections within a first time period, and then determines the reselection priority based on the mobility state.

[0272] Optionally, the terminal determines the mobility status based on the number of reselections in at least one of the following ways:

[0273] (1) The number of reselections is the first threshold, and the terminal is determined to be in a fixed state.

[0274] Optionally, the first threshold can be 0 or 1, or other values.

[0275] (2) If the number of reselections is less than the second threshold, the terminal is determined to be in a low mobility state.

[0276] (3) If the number of reselections is greater than the second threshold and less than the third threshold, the terminal is determined to be in the China Mobile state.

[0277] (4) If the number of reselections is greater than the third threshold, the terminal is determined to be in a high mobility state.

[0278] It should be noted that the first threshold is less than the second threshold, and the second threshold is less than the third threshold.

[0279] Among them, the movement speed in the low movement state is greater than the movement speed in the stationary state; the movement speed in the medium movement state is greater than the movement speed in the low movement state; and the movement speed in the high movement state is greater than the movement speed in the medium movement state.

[0280] It should be noted that the scheme for determining different mobility states based on the relationship between the number of reselections and the threshold in this embodiment is only an example. The terminal may also have other mobility states, and there may be other thresholds for determining mobility states. This embodiment does not limit the method of determining mobility states based on the number of reselections.

[0281] In some embodiments, the terminal determines its movement state based on its average moving speed over a second time period. Optionally, the terminal determines its movement state based on the speed range within which the average speed falls, and then determines the corresponding priority.

[0282] It should be noted that the terminal can determine its speed range based on its average moving speed during the second time period, and then determine the corresponding priority based on that speed range.

[0283] It should be noted that when the terminal determines the cell reselection priority in this embodiment, it needs to determine the reselection priority of the frequency when cell reselection is performed. Therefore, the terminal needs to determine the frequency of cell reselection first.

[0284] In some embodiments, the frequency at which the terminal performs cell reselection is third configuration information sent by the network device, which indicates one or more frequencies. These one or more frequencies refer to the frequencies corresponding to which the reselection priority needs to be determined.

[0285] In some embodiments, the frequency at which the terminal performs cell reselection is one or more frequencies corresponding to the first configuration information or the second configuration information.

[0286] In some embodiments, the frequency of cell reselection priority is based on the communication protocol. Alternatively, it can be understood that the frequency at which the terminal performs cell reselection is fixed based on the communication protocol.

[0287] It should be noted that the frequency corresponding to the reselection priority in this embodiment is the frequency of FR2.

[0288] In some embodiments, in response to the terminal's mobility information indicating a low mobility state and / or a fixed state, the terminal determines that the reselection priority corresponding to the frequency of FR2 is the highest priority. Alternatively, it can be understood that the terminal determines that the reselection priority corresponding to the frequency of FR2 is the highest priority when it determines that it is in a low mobility state and / or a fixed state. Optionally, the highest priority refers to the maximum value among configurable priorities.

[0289] In some embodiments, in response to the terminal's mobility information being in a low mobility state and / or a fixed state, the terminal determines the reselection priority of one or more frequencies as the highest priority, and the one or more frequencies are determined by the network device configuration.

[0290] It should be noted that the embodiments disclosed herein are illustrated using frequency as an example. In another embodiment, frequency may also be referred to as a frequency point.

[0291] It should be noted that the embodiments disclosed herein illustrate how to determine the reselection priority. Each scheme for determining the reselection priority is described below by way of example.

[0292] The first method involves the terminal receiving RRC release information (first configuration information) sent by the network device. This RRC release information includes dedicated indication information (second information), which applies to all frequencies. After the terminal enters the idle state, it determines the cell to camp on and receives broadcast information (second configuration information) within that cell. Frequency points 1, 2, and 3 are configured with their original priorities and the priorities corresponding to the UE's mobility state. The specific configurations are shown in Table 4.

[0293] Table 4

[0294] Among them, the terminal receives the low mobility / fixed status judgment information sent by the network device. The maximum number of reselections within the first time period. If the number of reselections within the first time period is less than (or equal to) the configured maximum number of reselections, the terminal adjusts the priority of frequency point 1 to priority 1b + sub-priority 1aa; the terminal adjusts the priority of frequency point 2 to priority 2b + sub-priority 2bb; and does not adjust the priority of frequency point 3.

[0295] Subsequently, if the number of reselections by the terminal within the first time period is greater than (or equal to) the configured maximum number of cell reselections, then the terminal adjusts the priority of frequency point 1 to the original priority 1a + sub-priority 1aa; the terminal adjusts the priority of frequency point 2 to the original priority 2a + sub-priority 2aa; and does not adjust the priority of frequency point 3.

[0296] The second method involves the terminal receiving an RRC release message from the network device. This RRC release message does not contain indication information (UE-specific indication information) or the indication information is configured as false. This indication information applies to all frequencies. The terminal enters an idle state, determines the cell to be camped, and receives a broadcast message from the cell to be camped. This message configures the original priorities for frequencies 1, 2, and 3, as well as the priorities corresponding to the UE's mobility state. See Table 4 for specific configurations. In this case, the terminal does not need to adjust priorities based on its state; the cell reselection priorities for frequencies 1, 2, and 3 are all the original priorities.

[0297] The third method involves the terminal receiving an RRC release message from the network device. This RRC release message contains indication information (UE-specific indication information) applicable to all frequencies. The terminal enters idle state, determines the cell it will camp on, and receives a broadcast message from the cell it will camp on. The network side indicates that frequencies 1, 2, and 3 require priority adjustment based on mobility state. The network side configures the original priority information for these frequencies.

[0298] The relationship between the number of reselections within the first time period and the maximum number of reselections is determined by the low mobility / fixed status sent by the terminal to the network device.

[0299] If the number of reselections by the terminal within the first time period is less than (or equal to) the maximum number of reselections configured, the terminal adjusts the priority of frequency points 1, 2, and 3 to the highest priority (i.e., the maximum value that the priority can be configured) plus the sub-priorities in the original priority information of these frequency points, and uses them for cell reselection.

[0300] Subsequently, if the number of reselections by the terminal within the first time period is greater than (or equal to) the configured maximum number of reselections, the terminal will adjust the priority of frequency points 1, 2, and 3 to the original priority plus the sub-priority in the original priority information.

[0301] The fourth method involves the terminal receiving an RRC release message from the network device. This message contains indication information (terminal-specific indication information) applicable to all frequencies. The terminal then enters an idle state and determines the cell to camp on. The network side has configured the original priority information for frequencies 1, 2, 3, 4, and 5. Frequencies 1, 2, and 3 are frequencies on FR2.

[0302] The relationship between the number of reselections within the first time period and the maximum number of reselections is determined by the terminal receiving the low mobility / fixed status information from the network side.

[0303] If the number of cell reselections by the terminal within the first time period is less than (or equal to) the maximum number of cell reselections configured, the terminal adjusts the priority of frequency points 1, 2, and 3 to the highest priority (i.e., the maximum value that the priority can be configured) plus the sub-priorities in the original priority information of these frequency points, and uses them for cell reselection.

[0304] Subsequently, if the number of cell reselections by the terminal within the first time period is greater than (or equal to) the configured maximum number of cell reselections, the terminal will adjust the priority of frequency points 1, 2, and 3 to the original priority plus the sub-priority in the original priority information.

[0305] The fifth method involves the terminal receiving an RRC release message from the network side. This release message contains indication information (proprietary indication information) applicable to all frequencies. The terminal enters an idle state, determines the cell it will camp on, and receives a broadcast message from the cell it will camp on. The original priorities for frequencies 1, 2, and 3, as well as the priorities corresponding to the terminal's mobility state, are configured as shown in Table 5.

[0306] Table 5

[0307] Among them, the first time period for determining the mobility status received by the terminal from the network device is TCRmax, the number of mobile cell reselections is NCR_M, and the number of mobile cell reselections is NCR_H.

[0308] If, during the first time period, the number of cell reselections (TCRmax) is less than NCR_M, the terminal applies the priority corresponding to the normal mobile state to frequency points 1 and 2; the terminal then performs cell reselection-related measurements and assessments based on the adjusted priority.

[0309] Subsequently, if, during the first time period, the number of cell reselections (TCRmax) is greater than or equal to NCR_M but less than or equal to NCR_H, the terminal will apply the priority corresponding to the mobile state to frequency points 1 and 2; the terminal will then perform cell reselection-related measurements and assessments based on the adjusted priority.

[0310] Subsequently, if the number of cell reselections during the first time period (TCRmax) is greater than NCR_H, the terminal will apply the priority corresponding to the high mobility state to frequency points 1 and 2; the terminal will then perform cell reselection-related measurements and assessments based on the adjusted priority.

[0311] During the process of terminal mobility status change, frequency point 3 always adopts the priority configured in the original priority information.

[0312] Step S2104: The terminal performs cell reselection based on the reselection priority.

[0313] In some embodiments, the terminal performs cell reselection based on the reselection priority of one or more frequencies.

After the wake-up delay, the terminal can start sending or receiving data, which not only improves the accuracy of the terminal waking up from the low-power state, but also improves the reliability of the terminal's communication.

[0346] In step S3103, the terminal performs cell reselection based on the reselection priority.

[0348] In some embodiments, the reselection priority is related to the priority of the frequency used for cell reselection.

[0372] Since the movement information does not correspond to a priority, the reselection priority is determined to be the original priority.

[0373] The mobile information does not correspond to a priority, so the reselection priority is determined to be the lowest priority.

[0381] The number of reselections is a first threshold, which determines that the terminal is in a fixed state;

[0382] If the number of reselections is less than the second threshold, the terminal is determined to be in a low-mobility state.

[0383] If the number of reselections is greater than the second threshold and less than the third threshold, the terminal is determined to be in a China Mobile state.

[0388] In some embodiments, determining the reselection priority based on the terminal's mobility information includes at least one of the following:

[0389] In response to the terminal's mobility information being in a low mobility state and / or a fixed state, the reselection priority corresponding to the frequency of FR2 is determined to be the highest priority;

[0390] In response to the terminal's mobility information indicating a low mobility state and / or a fixed state, one or more frequencies are determined as having the highest priority for reselection, wherein the one or more frequencies are determined by network device configuration.

[0391] Figure 4 is a flowchart illustrating a reselection priority determination method according to an embodiment of the present disclosure. As shown in Figure 4, the present disclosure relates to a reselection priority determination method, which includes:

[0392] Step S4101: The terminal adjusts the priority based on the network-side configuration information and mobility status.

[0393] Optionally, the terminal adjusts the priority of a specific frequency for cell re-allocation based on network-side configuration information and mobility status.

[0394] 1. In this case, the UE determines one or more specific frequencies whose priorities need to be adjusted based on mobility status, based on network indications or protocol agreements.

[0395] The priority refers to the priority of cell reselection, and different frequencies can correspond to different priorities.

[0396] The network-side configuration information described in section 2.1 includes any one or more of the following configuration information:

[0397] 2.1 Indication information, the indication information being used to indicate whether the UE needs to adjust the priority based on the mobility state;

[0398] 2.2 The priority corresponding to the UE's mobility state, such as the priority of a specific frequency for a UE in a low mobility state;

[0399] 2.2.1 The priority information corresponding to this mobility state can be configured through broadcast messages (such as SIB) or proprietary signaling (such as RRRCRelease);

[0400] 2.3 (Existing Priority Configuration): For each frequency, configure its original priority. This can include a priority CellReselectionPriority and a sub-priority CellReselectionSubPriority.

[0401] The indication information described in section 3.2.1 may include any one or more of the following types of information:

[0402] 3.1 The indication information may be public indication information applicable to a specific cell. This information is used to indicate whether the UE needs to adjust the priority based on the mobility state when performing cell reselection when the UE is camped in this cell.

[0403] 3.1.1 Based on this, the network side configures this indication information through broadcast information, such as any one or more of SIB1, SIB2, SIB4, and SIB5;

[0404] 3.1.2 The common indication information can also be specific to different frequencies under test, and one or more different frequencies under test can correspond to one or more indication information. When the UE is camped on this cell, cell reselection requires determining, based on this indication information, whether the UE needs to adjust the priority of these frequencies under test based on its mobility status.

[0405] 3.2 The indication information may be proprietary indication information applicable to a specific UE. This information is used to indicate whether the UE needs to adjust the priority based on the mobility state when the UE performs cell reselection.

[0406] 3.2.1 Based on this, the network side can configure indication information through RRC release messages;

[0407] The proprietary indication information mentioned in 3.2.2 can also be specific to different frequencies under test, with one or more different frequencies under test corresponding to one or more indication information. When the UE performs cell reselection, it needs to determine whether the UE needs to adjust the priority of these frequencies under test based on the mobility state, based on this indication information.

[0408] 3.3 If both proprietary and public instruction information are configured simultaneously, then:

[0409] 3.3.1 The UE shall use proprietary indication information and ignore common indication information;

[0410] 3.3.2 The UE needs to consider both simultaneously. Only when both the proprietary indication information and the common indication information of the camped cell are configured, or the indication is "true", can the UE adjust the priority of the corresponding frequency based on the mobility state.

[0411] 4. The priority corresponding to the UE's mobility state described in section 2.3 can be configured using any one or more of the following schemes:

[0412] 4.1 Priority under low mobility state (including stationary state);

[0413] 4.2 The correspondence (matching relationship) between different movement states and different priorities can be implemented, for example, by any one or more of the following methods:

[0414] 4.2.1 Method 1: A movement status and priority matching information table, where the movement status can contain {movement status 1, movement status 2, movement status 3, movement status 3...};

[0415] For example, movement states 1, 2, 3, 4, and 5 can correspond to movement states: fixed, low movement, normal movement, medium movement, and high movement, respectively. See Table 1 for example.

[0416] For another example, see Table 2.

[0417] 4.2.2 Method 2: Movement speed range and priority matching information table;

[0418] For example, see Table 3.

[0419] 5. The priority configuration for the UE's mobility state described in section 4 can correspond to a specific frequency or a specific set of frequencies:

[0420] 5.1 Per Frequency Scheme:

[0421] 5.1.1 For each frequency, the priority of this frequency when the UE enters a low mobility state;

[0422] 5.1.2 For each frequency, configure the matching information of the UE's mobility status and priority.

[0423] For this configuration method, this information can be used indirectly as an indication, or it can be used to indicate that the UE needs to adjust the priority of one or more frequencies based on the UE's mobility status.

[0424] 5.2 General Solution:

[0425] 5.2.1 For a specific group of frequencies, when the UE enters a low mobility state, the priority of this group of frequencies;

[0426] 5.2.2 For a specific set of frequencies, configure the matching information between the UE's mobility state and the priority corresponding to this set of frequencies.

[0427] 6. The UE determines, based on network configuration or protocol specifications, one or more frequencies (or frequency points) that require priority adjustment based on the UE's mobility state, i.e., the specific frequencies described in 1, which can be implemented through any one or more of the following methods:

[0428] 6.1 Receive a set of frequencies indicated in the message sent by the NW side;

[0429] 6.2 The indication information for different frequencies under test described in section 3 is used to determine one or more frequencies whose priority needs to be adjusted based on the UE's mobility state. When the indication information corresponding to this frequency is configured or set to "true", then this frequency is the frequency whose priority needs to be adjusted based on the UE's mobility state.

[0430] For example, the indication information can also be implemented through the configuration of the priority corresponding to the per-frequency movement state as described in 4 and 5.

[0431] 6.3 A set of frequencies that need to be prioritized based on the UE’s mobility state can also be determined without network configuration. The protocol stipulates that this set of frequencies refers to the frequencies of FR2.

[0432] The specific frequencies mentioned in 7.1 and the one or more frequencies mentioned in 2.2 that require priority adjustment based on the UE's mobility state refer to the carrier frequencies of FR2. That is, the information described in 2 can only be configured for frequencies on FR2.

[0433] 7.1 For example, if the indication information described in 2.1 is configured for a specific frequency, then the indication information can only be configured for frequencies on FR2;

[0434] 7.2 For example, for 2.3 to 2.6, only configuring the corresponding mobility-related priorities for cells on FR2 is supported.

[0435] 8. The UE may determine the UE's mobility status based on one or more of the following methods.

[0436] 8.1 Determine the UE's mobility status based on the number of cell reselections occurring within a specific time period:

[0437] For example,

[0438] For example, if the number of cell reselections within a specific time period is 0 or no more than 1, the UE is considered to be in a fixed state.

[0439] 8.2 The UE determines its movement status and speed range based on its average movement speed over a specific time period.

[0440] Based on steps 1-8, if the network side instructs the UE to adjust priorities based on mobility state, the UE determines its current mobility state using the method described in step 8. For a specific frequency whose priority needs to be adjusted, the UE selects the first priority corresponding to the current mobility state and sets the priority of this frequency as the first priority. If the current mobility state does not have a corresponding priority, the priority corresponding to this frequency is the original priority described in step 2.3. If no original priority is configured, its priority is considered to be the lowest priority.

[0441] 10. Based on 9, if the original priority contains sub-priorities, but the priority corresponding to the movement state described in 2 only contains the priority and not the sub-priorities, then any one or more of the following situations apply:

[0442] 10.1 If the UE selects the first priority corresponding to the current mobility state as described in 9, and sets the priority corresponding to this frequency as the first priority, then this priority is the priority of this frequency for cell reselection, i.e., ignoring the sub-priority part;

[0443] 10.2 If the UE selects the first priority corresponding to the current mobility state as described in 9, and sets the priority corresponding to this frequency as the first priority, then this priority plus the sub-priority in the original priority is the priority for this frequency to be used for cell reselection, that is, the sub-priority part remains unchanged.

[0444] If the priority parameters contained in the original priority are of the same category as the priority parameters in the priority corresponding to the movement state, then you can directly replace them.

[0445] Example 1: The UE receives an RRC release message sent by the network side. The release message contains indication information (UE-specific indication information). This indication information applies to all frequencies. The UE enters the idle state, determines the cell to be camped, and receives a broadcast message sent by the cell to be camped. The original priority and the priority corresponding to the UE's mobility state are configured for frequency points 1, 2, and 3. The specific configuration is shown in Table 4.

[0446] The maximum number of cell reselection attempts during the first time period after the UE receives low mobility / fixed status judgment information from the network side:

[0447] If the number of cell reselections by the UE within the first time period is less than (or equal to) the configured maximum number of cell reselections, then the UE adjusts the priority of frequency point 1 to priority 1b + sub-priority 1aa; then the UE adjusts the priority of frequency point 2 to priority 2b + sub-priority 2bb; the priority of frequency point 3 is not adjusted; the UE performs cell reselection-related measurements and evaluations based on the adjusted priorities.

[0448] Subsequently, if the number of cell reselections by the UE within the first time period is greater than (or equal to) the configured maximum number of cell reselections, then the priority of frequency point 1 is adjusted to the original priority 1a + sub-priority 1aa; then the priority of frequency point 2 is adjusted to the original priority 2a + sub-priority 2aa; the priority of frequency point 3 is not adjusted; the UE performs cell reselection-related measurements and evaluations based on the adjusted priorities.

[0449] Example 2:

[0450] The UE receives an RRC release message from the network side. This release message either does not contain indication information (UE-specific indication information) or the indication information is configured as false. This indication information applies to all frequencies. The UE enters an idle state, determines its cell, and receives a broadcast message from the cell it intends to use. This message configures the original priorities for frequencies 1, 2, and 3, as well as the priorities corresponding to the UE's mobility state. See Example 1 for specific configurations. Therefore, the UE does not need to adjust priorities based on its UE state; the cell reselection priorities for frequencies 1, 2, and 3 are all the original priorities.

[0451] Example 3:

[0452] The UE receives an RRC release message from the network side. This release message contains indication information (UE-specific indication information) applicable to all frequencies. The UE enters idle state, determines the cell to camp on, and receives a broadcast message from the cell to camp on. The frequencies that the network side indicates require priority adjustment based on mobility state are frequencies 1, 2, and 3. The network side configures the original priority information for these frequencies.

[0453] The maximum number of cell reselection attempts during the first time period after the UE receives low mobility / fixed status judgment information from the network side:

[0454] If the number of cell reselections for the UE within the first time period is less than (or equal to) the maximum number of cell reselections configured, the UE adjusts the priority of frequency points 1, 2, and 3 to the highest priority (i.e., the maximum value that the priority can be configured) plus the sub-priorities in the original priority information of these frequency points, and uses them for cell reselection.

[0455] Subsequently, if the number of cell reselections by the UE within the first time period is greater than (or equal to) the configured maximum number of cell reselections, the priority of frequency points 1, 2, and 3 of the UE will be adjusted to the original priority plus the sub-priority in the original priority information.

[0456] Example 4:

[0457] The UE receives an RRC release message from the network side. This release message contains indication information (UE-specific indication information) applicable to all frequencies. The UE enters idle state and determines the cell to camp on. The network side configures original priority information for frequencies 1, 2, 3, 4, and 5. Frequencies 1, 2, and 3 are frequencies on FR2.

[0458] The maximum number of cell reselection attempts during the first time period after the UE receives low mobility / fixed status judgment information from the network side:

[0459] If the number of cell reselections for the UE within the first time period is less than (or equal to) the maximum number of cell reselections configured, the UE adjusts the priority of frequency points 1, 2, and 3 to the highest priority (i.e., the maximum value that the priority can be configured) plus the sub-priorities in the original priority information of these frequency points, and uses them for cell reselection.

[0460] Subsequently, if the number of cell reselections by the UE within the first time period is greater than (or equal to) the configured maximum number of cell reselections, the priority of frequency points 1, 2, and 3 of the UE will be adjusted to the original priority plus the sub-priority in the original priority information.

[0461] Example 5:

[0462] The UE receives an RRC release message sent by the network side. The release message contains indication information (UE-specific indication information). This indication information applies to all frequencies. The UE enters the idle state, determines the cell to be camped, and receives a broadcast message sent by the cell to be camped. The original priority and the priority corresponding to the UE's mobility state are configured for frequency points 1, 2, and 3. The specific configuration is shown in Table 5.

[0463] The UE receives mobility status judgment information from the network side, including the first time period TCRmax, the number of mobile cell reselections (NCR_M) for medium time, and the number of mobile cell reselections (NCR_H) for high time.
