It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0060] To facilitate understanding of the technical solutions provided in this application, the main technical concepts involved in the embodiments of this application are briefly described below.

[0061] 1. Paging mechanism

[0062] The UE listens for the Downlink Control Information for paging Radio Network Temporary Identity (DCI for paging RNTI) scrambled with the paging radio network temporary identifier in the paging occasion (PO) associated with its own User Equipment Identity Document (UE_ID); if the DCI for paging RNTI is received, it may listen to the corresponding Physical Downlink Shared Channel (PDSCH) to receive the paging message.

[0063] 2. Power saving gain of the wake-up signal

[0064] The method of paging monitoring to save power includes: for UE that supports wake-up signals and the cell where it resides broadcasts the configuration information of the wake-up signal, before the PO arrives, the network side device will first send a wake-up signal (such as Early Paging Indication (PEI) or a low power wake-up signal (Low Power Wake Up Signal, LP-WUS); if the UE receives the wake-up signal, it needs to monitor the PO; otherwise, the UE does not need to monitor the PO.

[0065] Since the power consumed by the UE to receive the wake-up signal is much lower than directly monitoring the PO, and the wake-up signal can indicate whether the UE needs to monitor the corresponding PO, monitoring the wake-up signal can avoid the UE monitoring the PO, so the use of the wake-up signal can bring certain power saving gains.

[0066] At the same time, the current wake-up signal can be combined with PO grouping. PO grouping means that UEs monitoring the same PO can be classified into M groups, where M is a positive integer. The wake-up signal can wake up a group of UEs in the M groups, that is, the wake-up signal provides a finer-grained paging grouping than PO, further reducing the probability of the UE being awakened.

[0067] However, paging messages (such as paging DCI and paging PDSCH) are sent by all cells included in the Tracking Area List (TAlist) configured by the UE. That is, when the network-side device pages a UE, all cells included in its TAlist will wake up the paging group to which the UE belongs, that is, other UEs belonging to the same paging group as the UE (even if they do not reside in the same cell as the paged UE) are mistakenly awakened, which will result in certain power consumption.

[0068] In order to improve this problem, the concept of the last used cell is introduced. The last used cell is the cell where the UE receives the RRC release message for the last time, and the received RRC release message does not carry the indication information of not updating the last used cell (noLastCellUpdate). For a UE camped in a cell with the last used cell wake-up signal feature enabled, the UE monitors the wake-up signal only when the last used cell and the camp cell are consistent; in other cells (i.e., the last used cell of the UE is not the current camped cell), the UE does not use the wake-up signal and directly monitors the PO.

[0069] Accordingly, when the network - side device paging the UE, the cell that enables the last - used cell wake - up signal feature will send a wake - up signal to the UE only when it is the last - used cell of the paged UE; otherwise, no wake - up signal will be sent.

[0070] 3. Reselection Priority Handling

[0071] The absolute priorities of different NR frequencies (i.e., frequency points) or frequencies of inter - Radio Access Technology (inter - RAT, also known as heterogeneous systems) can be obtained through system messages, RRC release messages, or inherited from other Radio Access Technologies (RATs) during inter - RAT cell selection and reselection. When priorities are provided using dedicated signaling, the UE will ignore all priorities provided in the system message. If the UE is normally camped on a cell and has priorities for other frequencies except the current frequency provided by dedicated signaling, the UE will consider the current frequency to have the lowest priority.

[0072] The UE will only perform cell reselection evaluation on NR frequencies and inter - RAT frequencies configured in the system message and having priorities.

[0073] The configuration parameters of the cell reselection priority provided by the RRC release message mainly include:

[0074]

[0075] Among them, Ce11ReselectionPriorities represents the cell reselection priority, freqPriorityListEUTRA represents the Evolved Universal Terrestrial Radio Access (EUTRA) frequency priority list, freqPriorityListNR represents the NR frequency priority list, and t320 represents the timer value.

[0076]

[0077] Among them, FreqPriorityNR represents the NR frequency priority list, carrierFreq represents the reselection cell frequency point, cellReselectionPriority represents the cell reselection priority, and cellReselectionSubPriority represents the absolute priority used to calculate the frequency point.

[0078] 4. Inter-frequency and inter-RAT Cell Reselection Criteria

[0079] 4.1. When the NR frequency or inter-RAT frequency has a higher priority than the serving frequency

[0080] If the parameter threshServingLowQ is broadcast in the system information and the time since the UE camped on the current serving cell has exceeded 1 second, then the UE shall reselect to a cell on an NR frequency or inter-RAT frequency with a higher priority than the current serving frequency if the following conditions are met: within a time interval Treselection RAT a cell on a higher priority NR frequency or on an Evolved Universal Terrestrial Radio Access Network (EUTRAN) RAT (or frequency) satisfies the cell selection quality value Squal > threshold Thresh X,HighQ .

[0081] Otherwise, the UE shall reselect to a cell on an NR frequency or inter-RAT frequency with a higher priority than the current serving frequency if the following conditions are met:

[0082] within a time interval Treselection RAT a cell on a higher priority RAT or frequency satisfies the cell selection received level value Srxlev > threshold Thresh X,HighP ;

[0083] the time since the UE camped on the current serving cell has exceeded 1 second.

[0084] 4.2. When the NR frequency or inter-RAT frequency has a lower priority than the serving frequency

[0085] If the system information broadcasts the parameter threshServingLowQ, and the time since the UE has camped on the current serving cell has exceeded 1 second, the UE shall reselect to a cell on an NR frequency or an inter-RAT frequency with a lower priority than the current serving frequency if the following conditions are met: within a time interval Treselection RAT the serving cell satisfies the cell selection quality value Squal < the threshold Thresh Serving,LowQ and a lower priority NR or EUTRAN RAT (or frequency) satisfies the cell selection quality value Squal > the threshold Thresh X,LowQ .

[0086] Otherwise, if the following conditions are met, the UE shall reselect to a cell on an NR frequency or an inter-RAT frequency with a lower priority than the current serving frequency, and the conditions include:

[0087] within a time interval Treselection RAT the serving cell satisfies the cell selection received level value Srxlev < the threshold Thresh Serving,LowP and a cell of a lower priority RAT or frequency satisfies the cell selection received level value Srxlev > the threshold Thresh X,LowP ;

[0088] the time since the UE has camped on the current serving cell has exceeded 1 second.

[0089] It should be noted that in the cases described in 4.1 and 4.2, the cell selection received level value Srxlev satisfies:

[0090] Srxlev = Q rxlevmeas – (Q rxlevmin + Q rxlevminoffset ) – P compensation - Qoffset temp

[0091] where Q rxlevmeas represents the received level value of the measured cell, or the signal strength (i.e., the reference signal receiving power, RSPR) value, Q rxlevmin , Q rxlevminoffset , P compensation , Qoffset temp are all configured by the network side, P compensation represents the compensation value, Qoffset temp represents the access temporary offset, Q rxlevmin , Q rxlevminoffset are frequency-specific parameters, Qrxlevmin Represents the minimum received level value, Q rxlevminoffset Represents the minimum received level offset value. If the cell-specific parameter Q rxlevminoffsetcell Is also configured in the system information, then Q rxlevmin Satisfies: Q rxlevmin = Q rxlevmin + Q rxlevminoffsetcell .

[0092] The cell selection quality value Squal satisfies:

[0093] Squal = Q qualmeas – (Q qualmin + Q qualminoffset ) - Qoffset temp

[0094] Wherein, Q qualmeas Represents the measured cell quality (i.e., reference signal receiving quality, Reference Signal Receiving Quality, RSRQ) value, Q qualmin , Q qualminoffset , Qoffset temp Are all configured by the network-side device, Q qualmin Represents the minimum received signal quality, Q qualminoffset Represents the minimum received signal quality offset value, Qoffset temp Represents the access temporary offset.

[0095] In addition, in the cases described in 4.1 and 4.2, if more than one cell meets the above cell reselection related conditions, the terminal should select one cell from the more than one cell according to the following rules:

[0096] If the highest priority frequency is an NR frequency, reselect to the highest ranked cell that meets the R criterion on this frequency;

[0097] If the highest priority frequency is a frequency of other RAT, reselect to the strongest cell that meets the reselection criterion of this RAT on this frequency.

[0098] 4.3, R criterion

[0099] The terminal will use the R criterion to rank the serving cell and candidate neighbor cells in order to determine and reselect to the optimal cell.

[0100] The R criterion determines the parameters (R s , R n ) based on which the cell ranking is performed through the following two expressions:

[0101] For the serving cell: R s = Q meas,s + Q hyst-Qoffset temp

[0102] For neighboring cell: R n = Q meas,n -Qoffset - Qoffset temp

[0103] Wherein, Q meas,s 、Q meas,n represents the level value or signal strength (RSPR) measurement quantity (RSRP measurement quantity used in cell reselections) for cell reselection; Qoffset temp represents a cell-specific parameter; Q hyst represents the hysteresis value; Qoffset satisfies:

[0104] For the same frequency: If the cell-specific parameter Qoffset s,n is valid, it is equal to Qoffset s,n , otherwise it is equal to 0;

[0105] For different frequencies: If the cell-specific parameter Qoffset s,n is valid, it is equal to Qoffset s,n + the frequency-specific parameter Qoffset frequency , otherwise it is equal to Qoffset frequency .

[0106] In the related art, for a UE supporting a wake-up signal, it may be possible to use the wake-up signal only in a specific cell of the UE (such as the last used cell). When the UE leaves this specific cell, the UE cannot use the wake-up signal, so that the power saving gain of the UE is very limited. Especially when the UE has a relatively high requirement for power saving, how to enable the UE to enjoy as much power saving gain of the wake-up signal as possible is an urgent problem to be considered.

[0107] This application provides a cell processing method, apparatus, terminal, network-side device and readable storage medium, which can enable the terminal to enjoy as much power saving gain obtained by using the wake-up signal as possible.

[0108] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the cell processing method, apparatus, terminal, network-side device and readable storage medium provided by the embodiments of this application will be described in detail.

[0109] For ease of description, the following provides a unified description of the various terms involved in the embodiments of the present application. (Unless otherwise specified, the following unified description of each term applies to each embodiment of the present application. Given that the position of some individual terms when they first appear is relatively late, and except for not providing a unified description of these individual terms here, the following text will provide an explanation of these individual terms when they first appear):

[0110] Network-side device: It can be Figure 1 the network-side device 12 in

[0111] Terminal: It can be Figure 1 the terminal 11 in

[0112] Priority of a cell: It is the cell selection priority or cell reselection priority of the cell.

[0113] Priority of the frequency band where the cell is located: It is the cell selection priority or cell reselection priority of the frequency band where the cell is located, that is, the cell selection priority or cell reselection priority of all cells in the frequency band where the cell is located.

[0114] In the first aspect of the embodiments of the present application, a cell processing method is provided. This method is executed by a terminal. Refer to Figure 2 shown in

[0115] Step S101: The terminal executes at least one of the following:

[0116] The terminal performs cell selection or cell reselection according to the first priority information;

[0117] The terminal requests the network-side device to update the target cell of the terminal to the second cell where the terminal is currently camped, and the target cell is: the cell where the last radio resource control release message was received.

[0118] Among them, the first priority information is used to represent at least one of the following:

[0119] The priority of the target cell of the terminal is the highest;

[0120] The priority of the frequency band where the target cell of the terminal is located is the highest;

[0121] The terminal satisfies at least one of the following:

[0122] Supports listening for wake-up signals;

[0123] Is configured to listen for wake-up signals.

[0124] It should be noted that the activation of a non-last used cell (i.e., non-target cell) of the terminal indicates that the wake-up signal is only sent in the last used cell, or the non-last used cell does not send a wake-up signal or broadcast the configuration information of the wake-up signal. In this case, the cell reselection priority of the non-last used cell is the lowest; or lower than that of the last used cell.

[0125] In specific implementation, the first priority information can be agreed upon by the protocol or configured (or sent) by the network-side device. When the terminal performs cell selection or cell reselection according to the first priority information, it will set the priority of the last used cell to the highest or consider it the highest (corresponding to the case of protocol agreement), or set the priority of the frequency band where the last used cell is located to the highest or consider it the highest, that is, set the priority of all cells (including the last used cell) in the frequency band where the last used cell is located to the highest or consider it the highest. This can significantly increase the probability that the new resident cell selected by the terminal during cell selection or cell reselection is the last used cell, and further increase the possibility of supporting the terminal to use the wake-up signal, enabling the terminal to enjoy the power-saving gain of the wake-up signal as much as possible.

[0126] When the second cell where the terminal is currently resident is not the terminal's last used cell, and the second cell restricts that only the terminal with the last used cell as this cell (i.e., the second cell) can use the wake-up signal, the terminal can request the network-side device to update the second cell to the terminal's last used cell to use the wake-up signal in the currently resident second cell, so that the terminal can enjoy the power-saving gain of the wake-up signal as much as possible.

[0127] For example, the terminal can switch itself from the idle state to the connected state and request the network-side device to send an RRC release message in the second cell, thereby updating the second cell to the terminal's last used cell.

[0128] From the above steps, it can be seen that by adopting the method of updating the UE's last used cell to the currently resident cell, or by adjusting the relevant priority of the last used cell in cell selection or cell reselection to the highest to increase the possibility that the last used cell is determined as the new resident cell in cell selection or cell reselection, the possibility that the currently resident cell or the new resident cell of the terminal supports the terminal to use the wake-up signal can be significantly increased, thereby enabling the terminal to enjoy the power-saving gain obtained by using the wake-up signal as much as possible.

[0129] In some embodiments, the target cell of the terminal satisfies at least one of the following:

[0130] A wake-up signal has been sent;

[0131] Configuration information of the wake-up signal has been broadcast;

[0132] Wherein, the wake-up signal is used to indicate whether the terminal needs to monitor the paging occasion PO associated with the wake-up signal.

[0133] In some embodiments, the terminal also performs cell selection or cell reselection according to the second priority information, and the second priority information is used to characterize at least one of the following:

[0134] The priority of the first cell is the highest or the second highest;

[0135] The priority of the frequency band where the first cell is located is the highest or the second highest;

[0136] Wherein, the cell identifier of the first cell is different from the cell identifier of the target cell of the terminal, and the first cell satisfies: the first cell has sent a wake-up signal or broadcast configuration information of the wake-up signal, and the first cell does not indicate that only the terminal whose target cell is the first cell can use the wake-up signal in the first cell.

[0137] It should be noted that if the priorities of the first cell and the last used cell are both the highest, the UE can select one of them as the cell with the highest priority by itself.

[0138] In specific implementation, considering that in the cell that has sent the wake-up signal, there is no restriction that only the UE whose last used cell is this cell can use the wake-up signal (i.e., the above-mentioned first cell), and it is also possible to support the terminal (i.e., the terminal whose last used cell is not the first cell) to use the wake-up signal. In this embodiment, by means of this second priority information, the priority of the first cell is set to the highest (or the second highest), or the terminal is made to think that it is the highest (or the second highest), or the priority of the frequency band where the first cell is located is set to the highest (or the second highest), or the terminal is made to think that it is the highest (or the second highest), that is, the priorities of all cells (including the first cell) in the frequency band where the first cell is located are set to the highest (or the second highest), or the terminal is made to think that it is the highest (or the second highest). Subsequently, the terminal will preferentially (or secondly preferentially) camp on the first cell with the highest (or the second highest) priority, thereby further increasing the possibility that the new camped cell selected by the terminal for cell selection or cell reselection supports the terminal to use the wake-up signal, so that the terminal can enjoy the power-saving gain of the wake-up signal as much as possible.

[0139] In some embodiments, the method further includes at least one of the following:

[0140] The terminal receives control messages such as an RRC release message, an RRC reject message, etc. carrying at least one of the first priority information and the second priority information;

[0141] The terminal receives broadcast messages such as a System Information Block (SIB) carrying at least one of the first priority information and the second priority information.

[0142] In some embodiments, the first priority information or the second priority information is valid before the first timer times out, and the method further includes:

[0143] When the terminal receives a control message carrying at least one of the first priority information and the second priority information, the terminal starts or restarts the first timer.

[0144] In specific implementation, a timer (i.e., the first timer) is configured for the terminal. When the terminal receives a control message (or a broadcast message) such as an RRC release message carrying at least one of the first priority information and the second priority information, the terminal starts or restarts the first timer. Before the first timer times out, the terminal considers the cell reselection priority of the last used cell of the UE indicated by at least one of the first priority information and the second priority information and the cell reselection priority of the first cell to be valid. By introducing the first timer to set a validity period for the cell reselection priority configured by at least one of the first priority information and the second priority information, the reliability of the cell reselection priority configured in the first priority information and the second priority information can be improved.

[0145] In some embodiments, when the terminal receives a control message and the control message carries at least the priority information of the first cell, the method further includes one or more of the following:

[0146] The terminal stores the priority information of the first cell;

[0147] After the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information, when the terminal receives a broadcast message carrying the second priority information from the currently resident cell, the terminal updates the stored priority information of the first cell according to the second priority information.

[0148] In specific implementation, when the control message carries the priority information of the first cell, the terminal will store the priority information of the first cell carried by the control message, so as to perform cell selection or reselection according to the stored priority information of the first cell subsequently.

[0149] Optionally, when both the broadcast message and the control message carry the priority information of the first cell, the terminal will consider the priority information of the first cell carried by the control message to be valid and store the priority information of the first cell carried by the control message, thereby solving the configuration conflict of the priority information of the first cell.

[0150] After the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information, if the network side device broadcasts the priority information of the first cell through the currently resident cell (that is, the terminal receives a broadcast message carrying the second priority information from the currently resident cell), the terminal will update the stored priority information of the first cell, such as adding the second priority information to the stored priority information of the first cell, or overwriting the stored priority information of the first cell with the second priority information, to ensure the reliability and comprehensiveness of the priority information of the first cell stored by the terminal.

[0151] Optionally, if the network side device broadcasts the priority information of the first cell in the new currently resident cell, and the control message received by the terminal most recently does not carry the priority information of the first cell (or the carried priority information of the first cell has expired), the terminal will update the stored priority information of the first cell according to the broadcast second priority information, to further ensure the reliability of the priority information of the first cell stored by the terminal.

[0152] In some embodiments, when there are multiple rules to determine the cell or frequency point with the highest priority, the method further includes at least one of the following:

[0153] The terminal determines the target rule based on the priority rules agreed by the protocol;

[0154] The terminal determines the target rule by itself;

[0155] The target rule is the rule that specifies the cell or frequency point with the highest priority.

[0156] In specific implementation, considering that when the determination of the priority is related to multiple characteristics (that is, related to multiple rules), there is a situation where the protocol agreement or the network side device instructs the UE to consider that the priorities of multiple cells or frequency points are the highest. At this time, the terminal can determine or determine by itself or configure the target rule by the network side device based on the protocol agreement. Subsequently, the terminal can determine the cell or frequency point with the highest priority according to the target rule, thereby solving the conflict of the highest priority.

[0157] For example, when the UE supports vehicle-to-everything (V2X) or NR sidelink, or the UE supports a high-speed data network (HSDN) and the UE supports a wake-up signal, the UE considers, according to the protocol, that the HSDN cell, the frequency points providing NR sidelink and V2X sidelink communication configurations are all of the highest priority. However, it is impossible for multiple types of cells to be the highest-priority cells simultaneously. At this time, it can be agreed in the protocol that the UE considers the HSDN cell as the cell with the highest cell reselection priority, or it can be agreed in the protocol that the frequency points providing NR sidelink and V2X sidelink communication configurations are the frequency points with the highest cell reselection priority (corresponding to the case where the terminal determines the target rule based on the protocol agreement), or it is determined based on the UE implementation which frequency points related to the feature are the frequency points with the highest priority (corresponding to the case where the terminal determines the target rule by itself).

[0158] In some embodiments, the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information. According to the different information represented in the first priority information or the second priority information, it can be divided into the following two cases.

[0159] Case 1: Adjust the priority at the frequency point granularity.

[0160] In Case 1, the first priority information or the second priority information can adjust the priority at the frequency point granularity, that is, the first priority information can be used to represent that the frequency point where the last used cell is located has the highest priority, and the second priority information represents that the frequency point where the first cell is located has the highest or second-highest priority.

[0161] For example, the network-side device can use a control message (or a broadcast message) to send at least one of the first priority information and the second priority information to the terminal to set the frequency point where the last used cell or the first cell of the UE is located as the frequency point with the highest priority. When the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information, it will preferentially camp on the cell under the highest-priority frequency point (such as the last used cell or the first cell of the UE).

[0162] For another example, the network-side device may use a control message (or a broadcast message) to send the first priority information to the terminal, so as to set the frequency band where the last used cell of the UE is located as the frequency band with the highest priority, and send the second priority information to set the frequency band where the first cell is located as the frequency band with the second highest priority. When the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information, it will preferentially camp on the cell under the highest priority frequency band (such as the last used cell of the UE), and secondly preferentially camp on the cell under the second highest priority frequency band (such as the first cell).

[0163] Case 2: Adjust the priority at the cell granularity.

[0164] In Case 2, the first priority information or the second priority information can adjust the priority at the cell granularity, that is, the first priority information can be used to indicate that the priority of the last used cell is the highest, and the second priority information can indicate that the priority of the first cell is the highest or the second highest.

[0165] For example, the network-side device may use a control message (or a broadcast message) to send the first priority information to the terminal to set the last used cell of the UE as the cell with the highest priority; or send the second priority information to the terminal to set the first cell as the cell with the highest priority. When the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information, it will preferentially camp on the last used cell of the UE or the first cell.

[0166] For another example, the network-side device may use a control message (or a broadcast message) to send the first priority information to the terminal to set the last used cell of the UE as the cell with the highest priority, and send the second priority information to set the first cell as the cell with the second highest priority. When the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information, it will preferentially camp on the last used cell of the UE, and secondly preferentially camp on the first cell.

[0167] In some embodiments, the first priority information or the second priority information includes at least one of the following:

[0168] Item A-1: The first indication information, which is used to indicate that the priority of the first cell is the highest or the second highest;

[0169] Item A-2: The second indication information, which is used to indicate that the priority of the target cell of the terminal is the highest;

[0170] Item A-3: The third indication information is used to indicate that the priority of the frequency band where the first cell is located is the highest or the second highest;

[0171] Item A-4: The fourth indication information is used to indicate that the priority of the frequency band where the target cell of the terminal is located is the highest;

[0172] Item A-5: The identification information of the first cell.

[0173] For Item A-1, it needs to be used in combination with Item A-5. Item A-5 is used to inform the UE of the identification information of the first cell, and Item A-1 clearly indicates (i.e., directly indicates) that the priority of the first cell is the highest or the second highest.

[0174] For Item A-2, the network-side device can use a control message (or a broadcast message) to send the second indication information (such as a bit or a bit string with a specific value) to the terminal to indicate that the priority of the terminal's last used cell is the highest.

[0175] For Item A-3, it needs to be used in combination with Item A-5. Item A-5 is used to inform the UE of the identification information of the first cell, and Item A-3 clearly indicates (i.e., directly indicates) that the priority of the frequency band where the first cell is located is the highest or the second highest.

[0176] For Item A-4, the network-side device can use a control message (or a broadcast message) to send the fourth indication information (such as a bit or a bit string with a specific value) to the terminal to indicate that the priority of the frequency band where the terminal's last used cell is located is the highest.

[0177] For Item A-5, it can be pre-agreed that after the terminal receives the identification information of a certain cell, it will determine that cell as the first cell and set the priority of the first cell to the highest or the second highest. Subsequently, the network-side device can use the method of sending the identification information of the first cell to the terminal to imply (i.e., indirectly indicate) that the priority of the first cell (or the frequency band where the first cell is located) is the highest or the second highest.

[0178] Optionally, the network-side device can also use the method of sending the identification information of the first cell to the terminal to imply that the priority of the terminal's last used cell is the highest.

[0179] In some embodiments, considering that the combination of the frequency band and the cell identification can uniquely identify a cell, the above-mentioned identification information of the first cell may include cell identifications such as the frequency band where the first cell is located and the Physical Cell Identifier (PCI) of the first cell.

[0180] For example, after receiving the identification information including the frequency point and PCI, the terminal can know that the cell identified by the frequency point and PCI allows UEs whose last used cell is not this cell to use the wake-up signal (i.e., determine that this cell is the first cell). When performing cell selection or reselection, the UE will consider the last used cell as the cell with the highest cell reselection priority and consider this cell as the cell with the highest or the second highest cell reselection priority.

[0181] In some embodiments, the identification information of the first cell is carried by at least one of the following:

[0182] Control message;

[0183] Broadcast message;

[0184] Configuration information of the frequency point where the first cell is located in the cell reselection configuration information.

[0185] In specific implementation, when the network side device sends the identification information of the first cell to the terminal, it can use a control message or a broadcast message to carry the identification information of the first cell, or use the configuration information of the frequency point where the first cell is located in the cell reselection configuration information, that is, the cell reselection configuration information of the frequency point, to carry the identification information of the first cell, where the cell reselection configuration information can be carried by a control message or a broadcast message.

[0186] Taking the identification information of the first cell including the PCI of the first cell and the frequency point where the first cell is located as an example, the network side device can carry the PCI of the first cell through the configuration information of the frequency point where the first cell is located in the cell reselection configuration information. The terminal can determine the PCI of the first cell and the frequency point where the first cell is located according to the PCI carried by the configuration information and the frequency point where the configuration information is located. Thus, through the configuration information of the frequency point where the first cell is located in the cell reselection configuration information, the carrying of the identification information of the first cell is realized.

[0187] The implementation manners of case 2 are further described below through Example 1 to Example 3.

[0188] Example 1: The network side device includes 1-bit indication information (i.e., the second indication information) in the RRC release message to indicate that the UE sets the UE's last used cell as the cell with the highest priority, and includes the frequency points and PCI of one or more first cells (i.e., the identification information of the first cell) in the RRC release message or the SIB to indicate to the UE which cells are the first cells and indicate that the priority of the first cell is the second highest priority.

[0189] Example 2: The network side device includes the frequencies and PCI (or other cell identifiers) of one or more first cells in the RRC release message or SIB, so as to directly indicate which cells are the first cells and the priority of the first cells is the second highest priority, and at the same time implicitly indicate that the UE's last used cell is the cell with the highest priority.

[0190] Example 3: The network side device includes the frequencies and PCI (i.e., the identification information of the first cells) of multiple first cells in the RRC release message or SIB, and can also include the corresponding PCI in the configuration information of the frequencies where the multiple first cells are located in the cell reselection configuration information in the RRC release message, so as to indicate which cells in the cell list included under the frequency are the first cells, and in a manner agreed by the protocol, make the UE consider that the cell reselection priority of the first cells is the second highest priority, and at the same time consider that the UE's last used cell is the cell with the highest cell reselection priority.

[0191] In some embodiments, the protocol agrees or the network side device configures (or sends) a first parameter or a second parameter. For example, the network side device can carry the first parameter or the second parameter in a control message or a broadcast message and send it to the terminal.

[0192] Among them, the first parameter is used to increase the probability that the terminal selects to camp on the UE's last used cell, and the second parameter is used to increase the probability that the terminal selects to camp on the first cell. Specifically, it can include the following four cases.

[0193] Case 1: The terminal calculates a sorting reference value of the serving cell associated with the target cell of the terminal based on the first parameter.

[0194] In Case 1, when the UE's current camping cell is the last used cell, when the terminal performs cell reselection evaluation, it can determine the sum of R s and the first parameter (which can be understood as an offset value, and this offset value is greater than 0) as the sorting reference value of the serving cell associated with the last used cell, so as to improve the probability that the terminal selects to camp on the UE's last used cell by optimizing the position of the last used cell in the cell sorting (which is determined by the size of the sorting reference value).

[0195] Case 2: The terminal calculates a sorting reference value of the neighboring cell associated with the target cell of the terminal based on the first parameter.

[0196] In Case 2, when the current resident cell of the UE is not the last used cell, when the terminal performs cell reselection evaluation, it can determine the sum of R n and the first parameter as the sorting reference value of the neighbor cell associated with the last used cell, so as to improve the probability that the terminal selects to reside in the last used cell of the terminal by optimizing the position of the last used cell in cell sorting.

[0197] Case 3: The terminal calculates the sorting reference value of the serving cell associated with the first cell based on the second parameter.

[0198] In Case 3, when the current resident cell of the UE is the first cell, when the terminal performs cell reselection evaluation, it can determine the sum of R s and the second parameter (which can be understood as an offset value, and this offset value is greater than 0) as the sorting reference value of the serving cell associated with the first cell, so as to improve the probability that the terminal selects to reside in the first cell by optimizing the position of the first cell in cell sorting.

[0199] Case 4: The terminal calculates the sorting reference value of the neighbor cell associated with the first cell based on the second parameter.

[0200] In Case 4, when the current resident cell of the UE is not the first cell, when the terminal performs cell reselection evaluation, it can determine the sum of R n and the second parameter as the sorting reference value of the neighbor cell associated with the first cell, so as to improve the probability that the terminal selects to reside in the first cell by optimizing the position of the first cell in cell sorting.

[0201] In some embodiments, the first parameter and the second parameter can be the same or different parameters.

[0202] It should be noted that for the serving cell and the neighbor cell for which the first parameter and the second parameter are not introduced, the sorting reference values of the serving cell and the neighbor cell can be R s and R n , R s and R n . The definitions of R

[0203] In some embodiments, when the UE meets certain conditions (such as the first condition, or other conditions set according to actual needs), the UE requests the network-side device to update the UE's last used cell to the current resident cell, which can reduce the number of times the UE requests to update the last used cell, so as to avoid frequent updates of the last used cell.

[0204] Specifically, when the first condition is satisfied, the terminal sends first information to the network device in the second cell where the terminal is currently camped, and the first information is used to request the network device to update the target cell of the terminal to the second cell where the terminal is currently camped;

[0205] Wherein, the first condition includes one or more of the following:

[0206] Item B-1: The duration for which the terminal has camped in the second cell is greater than a first threshold;

[0207] Item B-2: The second timer expires;

[0208] Item B-3: The mobility of the terminal is lower than a mobility threshold;

[0209] Item B-4: The paging probability of the terminal in the second cell exceeds a second threshold;

[0210] Item B-5: The number of paging times of the terminal before the second timer expires exceeds a third threshold;

[0211] Item B-6: Since the terminal has camped in the second cell, the number of paging times of the terminal exceeds a fourth threshold;

[0212] Item B-7: Since the terminal has camped in the second cell, the paging probability of the terminal is higher than a fifth threshold;

[0213] Item B-8: The target cell stored by the terminal is not the second cell;

[0214] Item B-9: The second cell has sent a wake-up signal or configured configuration information of a wake-up signal, and the second cell indicates that only terminals whose target cell is the second cell can use the wake-up signal in the second cell.

[0215] For items B-1 to B-3, they are mainly used to measure whether the terminal will camp in the second cell for a long time. By updating the last used cell of the terminal that will camp in the second cell for a long time, frequent updates of the last used cell can be avoided, and the terminal can enjoy the power-saving gain of the wake-up signal as much as possible in the second cell.

[0216] For items B-4 to B-7, they are mainly used to measure whether the terminal will be frequently paged in the second cell. By updating the last used cell of the terminal that will be frequently paged in the second cell, frequent updates of the terminal's last used cell can be avoided, and the probability that the terminal (or other terminals that jointly monitor a PO with this terminal) is woken up by mistake due to not using the wake-up signal can be significantly reduced. Thus, the terminal can enjoy as much power-saving gain of the wake-up signal as possible in the second cell.

[0217] For items B-8 and B-9, they are mainly used to determine whether the last used cell of the UE needs to be updated to the second cell so that the terminal can use the wake-up signal in the second cell. Thus, the terminal can enjoy as much power-saving gain of the wake-up signal as possible in the second cell.

[0218] In some embodiments, the configuration method of one or more parameters among the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, or the duration of the second timer includes at least one of the following:

[0219] Configure using the RRC release message. For example, the network-side device can configure one or more of the above-mentioned UE-specific parameters in the RRC release message according to the characteristics of the UE;

[0220] Agreed by the protocol;

[0221] Broadcast by the second cell. For example, the second cell broadcasts how long (corresponding to the first threshold) it can request to update the last used cell to this cell when resident in this cell, or the second cell broadcasts under what circumstances the paging probability of the UE (corresponding to the second threshold) is high enough to request to update the last used cell to this cell, etc.;

[0222] Carried in the Non-Access Stratum (NAS) message;

[0223] Determined through negotiation between the terminal and the network-side device. For example, the UE sends parameters such as the first threshold or the duration of the first timer it expects in the RegistrationRequest message, and the network-side device returns the finally determined first threshold or the duration of the first timer, etc. to the UE in the Registration Accept message;

[0224] Determined by the terminal itself. For example, the terminal determines one or more of the above-mentioned parameters based on its own preferences or implementation.

[0225] In some embodiments, when configuring one or more of the above parameters using multiple configuration methods, the configuration method to be adopted may be determined according to the priority of each configuration method agreed upon by the protocol.

[0226] In some embodiments, the method further includes:

[0227] When the terminal receives the configuration information of the duration of the second timer, the terminal starts the second timer.

[0228] In specific implementation, the terminal determines the moment when it receives the configuration information of the duration of the second timer as the moment to start the second timer. The moment when the terminal receives the configuration information of the duration of the second timer may include the frame, subframe, time slot, OFDM symbol where the configuration information is located, or minutes (m), milliseconds (ms), etc.

[0229] In some embodiments, the first information is used to characterize at least one of the following:

[0230] The terminal expects the network-side device to update the target cell of the terminal to the second cell;

[0231] The terminal expects to apply a wake-up signal or an application power-saving mechanism;

[0232] The paging frequency of the terminal, which facilitates the network-side device to reasonably determine whether to update the last used cell of the terminal according to whether the paging frequency of the terminal is high;

[0233] The power-saving requirement of the terminal, which facilitates the network-side device to reasonably determine whether to update the last used cell of the terminal according to whether the power-saving requirement of the terminal is high;

[0234] The power consumption level of the terminal, which facilitates the network-side device to reasonably determine whether to update the last used cell of the terminal according to whether the power consumption level of the terminal is high;

[0235] The paging probability of the terminal, which facilitates the network-side device to reasonably determine whether to update the last used cell of the terminal according to whether the paging probability of the terminal is high.

[0236] In some embodiments, the first information is carried in at least one of the following messages:

[0237] Non-access stratum (NAS) messages. For example, the network-side device may carry the first information through a message for location area update (such as a Registration request message);

[0238] User experience Assistance Information (UAI);

[0239] Radio Resource Control Resume Complete (RRCResumeComplete) message;

[0240] Radio Resource Control Setup Request (RRCSetupRequest) message, used to indicate that the reason for the terminal to establish a connection is to update the terminal's last used cell;

[0241] Radio Resource Control Resume Request (RRCResumeRequest) message, used to indicate that the reason for the terminal to resume a connection is to update the target cell of the terminal.

[0242] In the second aspect of the embodiments of the present application, another cell processing method is provided. This method is executed by a network-side device. Refer to Figure 3 As shown, it is a flowchart of the implementation of another cell processing method provided by the embodiments of the present application. This method may include the following steps:

[0243] Step S201: The network-side device performs at least one of the following:

[0244] The network-side device sends first priority information to the terminal;

[0245] The network-side device updates the target cell of the terminal to the second cell where the terminal is currently camped. The target cell is: the cell where the last Radio Resource Control Release message was received.

[0246] Among them, the first priority information is used to indicate at least one of the following:

[0247] The priority of the target cell of the terminal is the highest;

[0249] The terminal satisfies at least one of the following:

[0250] Supports listening for wake-up signals;

[0251] Is configured to listen for wake-up signals.

[0252] As can be seen from the above steps, by updating the UE's last used cell to the currently camped cell, or by adjusting the relevant priority of the last used cell to the highest in cell selection or cell reselection, so as to increase the possibility that the last used cell is determined as the new camped cell in cell selection or cell reselection, the possibility that the current camped cell or the new camped cell of the terminal supports the terminal to use the wake-up signal can be significantly increased, thereby enabling the terminal to enjoy as much power-saving gain obtained by using the wake-up signal as possible.

[0253] In some embodiments, the target cell of the terminal satisfies at least one of the following:

[0254] The wake-up signal has been sent;

[0255] The configuration information of the wake-up signal has been broadcast;

[0256] Wherein, the wake-up signal is used to indicate whether the terminal needs to monitor the paging occasion PO associated with the wake-up signal.

[0257] In some embodiments, the network-side device also sends second priority information to the terminal, and the second priority information is also used to characterize at least one of the following:

[0258] The priority of the first cell is the highest or the second highest;

[0259] The priority of the frequency band where the first cell is located is the highest or the second highest;

[0260] Wherein, the cell identifier of the first cell is different from the cell identifier of the terminal's last used cell, and the first cell satisfies: the first cell has sent the wake-up signal or broadcast the configuration information of the wake-up signal, and the first cell does not indicate that only the terminal with the last used cell being the first cell can use the wake-up signal in the first cell.

[0261] In some embodiments, it further includes at least one of the following:

[0263] The network-side device sends a broadcast message carrying at least one of the first priority information and the second priority information to the terminal.

[0264] In some embodiments, the first priority information or the second priority information is valid before the first timer times out. The first timer starts or restarts when the terminal receives a control message carrying at least one of the first priority information and the second priority information.

[0265] In some embodiments, the method further includes:

[0266] The network side device sends a broadcast message carrying at least one of the first priority information and the second priority information to the terminal through the terminal's new resident cell.

[0267] In some embodiments, the first priority information or the second priority information includes at least one of the following:

[0268] First indication information for indicating that the priority of the first cell is the highest or the second highest;

[0269] Second indication information for indicating that the priority of the terminal's last used cell is the highest;

[0270] Third indication information for indicating that the priority of the frequency band where the first cell is located is the highest or the second highest;

[0271] Fourth indication information for indicating that the priority of the frequency band where the terminal's target cell is located is the highest;

[0272] Identification information of the first cell.

[0273] In some embodiments, the identification information of the first cell is carried by at least one of the following:

[0274] Control message;

[0275] Broadcast message;

[0276] Configuration information of the frequency band where the first cell is located in the cell reselection configuration information.

[0277] In some embodiments, the method further includes at least one of the following:

[0278] The network side device sends a first parameter to the terminal, and the first parameter is used to increase the probability that the terminal selects to camp on the terminal's last used cell;

[0279] The network side device sends a second parameter to the terminal, and the second parameter is used to increase the probability that the terminal selects to camp on the first cell.

[0280] In some embodiments, at least one of the first parameter and the second parameter satisfies one of the following:

[0281] Carried in the control message;

[0282] Carried in the broadcast message.

[0283] In some embodiments, before the network - side device updates the target cell of the terminal to the second cell where the terminal is currently camped, the method further includes:

[0284] The network - side device receives first information sent by the terminal in the second cell where the terminal is currently camped. The first information is sent when a first condition is met and is used to request the network - side device to update the target cell of the terminal to the second cell where the terminal is currently camped;

[0291] Since the terminal camps in the second cell, the number of times the terminal is paged exceeds a fourth threshold;

[0292] Since the terminal camps in the second cell, the paging probability of the terminal is higher than a fifth threshold;

[0293] The target cell stored by the terminal is not the second cell;

[0294] The second cell sends a wake - up signal or configures configuration information of the wake - up signal, and the second cell indicates that only the terminal whose target cell is the second cell can use the wake - up signal in the second cell.

[0295] In some embodiments, the configuration methods of the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, or the duration of the second timer include at least one of the following:

[0296] Configured using the RRC release message;
