It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.
[0062] To facilitate understanding of the technical solutions provided by this application, the main technical concepts involved in the embodiments of this application are briefly described below.
[0063] 1. Paging mechanism
[0064] The UE monitors the downlink control information for paging radio network temporary identity (DCI for paging RNTI) scrambled with the paging radio network temporary identifier at the paging occasion (PO) associated with its own terminal identity (User Equipment Identity Document, UE_ID); if the DCI for paging RNTI is received, it may monitor the corresponding physical downlink shared channel (PDSCH) to receive the paging message.
[0065] 2. Power saving gain of wake-up signal
[0066] The method of paging monitoring power saving includes: for UEs that support wake-up signals and the cell where they are located 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 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.
[0067] Since the power consumed by the UE receiving 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.
[0068] 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 divided 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.
[0069] However, paging messages (such as paging DCI and paging PDSCH) are sent to all cells included in the Tracking Area List (TA list) configured for the UE. That is, when the network-side device pages a UE, all cells included in its TA list will wake up the paging group where the UE is located. That is, other UEs that belong to the same paging group as the UE (even if they do not reside in the same cell as the paged UE) are mistakenly woken up, which will result in certain power consumption.
[0070] To improve this problem, the concept of the last used cell is introduced. The last used cell is the cell in which the UE last received an RRC release message, and the received RRC release message does not carry the noLastCellUpdate indication. For a UE camped on a cell with the last used cell wake-up signal feature enabled, the UE monitors for wake-up signals only when the last used cell and the camp cell are the same. In other cells (i.e., the UE's last used cell is not the current camped cell), the UE does not use wake-up signals and directly monitors for PO.
[0071] Accordingly, when the network-side device pages a UE, a cell with the last used cell wake-up signal feature enabled sends a wake-up signal to the UE only if it is the last used cell of the paged UE; otherwise, no wake-up signal is sent.
[0072] 3. Reselect priority processing
[0073] The absolute priorities of different NR frequencies (i.e., frequency points) or inter-Radio Access Technology (inter-RAT) frequencies can be determined 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 system messages. If the UE is normally stationed in a cell and has other priorities provided by dedicated signaling besides the current frequency, the UE will consider the current frequency to have the lowest priority.
[0074] The UE will only perform cell reselection evaluation on the NR frequencies configured in the system message and the inter-RAT frequencies with priority.
[0075] The configuration parameters of the cell reselection priority provided by the RRC release message mainly include:
[0076] 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.
[0077] Among them, FreqPriorityNR represents the NR frequency priority list, carrierFreq represents the reselected cell frequency, cellReselectionPriority represents the cell reselection priority, and cellReselectionSubPriority represents the absolute priority used to calculate the frequency.
[0078] 4. Inter-frequency and inter-RAT cell reselection criteria
[0079] 4.1. The situation where 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 terminal camped on the current serving cell has exceeded 1 second, the terminal 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: RAT A cell with a higher priority NR frequency or Evolved Universal Terrestrial Radio Access Network (EUTRAN) RAT (or frequency) satisfies the cell selection quality value Squal> threshold Thresh X,HighQ .
[0081] Otherwise, the terminal 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] Treselection in a time interval RAT A cell with a higher priority RAT or frequency satisfies the cell selection reception level value Srxlev> threshold Thresh X,HighP ;
[0083] The time since the terminal camped on the current serving cell has exceeded 1 second.
[0084] 4.2. The situation where the NR frequency or inter-RAT frequency has a lower priority than the serving frequency.
[0085] If the parameter threshServingLowQ is broadcast in the system information and the time since the terminal camped on the current serving cell has exceeded 1 second, the terminal shall reselect to a cell on an NR frequency or inter-RAT frequency with a lower priority than the current serving frequency if the following conditions are met: RAT Within, the serving cell satisfies the cell selection quality value Squal < threshold ThreshServing,LowQ and the lower priority NR or EUTRAN RAT (or frequency) satisfies the cell selection quality value Squal > threshold Thresh X,LowQ .
[0086] Otherwise, the terminal shall reselect to a cell on an NR frequency or inter-RAT frequency with a lower priority than the current serving frequency if the following conditions are met:
[0087] Treselection in a time interval RAT Within the range, the serving cell satisfies the cell selection reception level value Srxlev < threshold ThreshServing,LowP and a cell of a lower priority RAT or frequency satisfies the cell selection reception level value Srxlev > threshold Thresh X,LowP ;
[0088] The time since the terminal 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 reception level value Srxlev satisfies:
[0090] Srxlev=Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp
[0091] Among them, Q rxlevmeas Indicates the received level value of the measured cell, or the signal strength (ie, reference signal received power, Reference Signal Receiving Power, RSPR) value, Q rxlevmin , Q rxlevminoffset 、P compensation 、Qoffset temp All are configured by the network side, P compensation Indicates the compensation value, Qoffset temp Indicates access temporary offset, Q rxlevmin , Q rxlevminoffset is a frequency-specific parameter, Qrxlevmin Indicates the minimum receiving level value, Q rxlevminoffset Indicates the minimum receiving level offset value. If the cell-specific parameter Q rxlevminoffsetcell Also configured in the system information, then Q rxlevmin Satisfaction: 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] Among them, Q qualmeas Indicates the measured cell quality (ie, Reference Signal Receiving Quality, RSRQ) value, Q qualmin , Q qualminoffset 、Qoffset temp All are configured by network side devices, Q qualmin Indicates the minimum received signal quality, Q qualminoffset Indicates the minimum received signal quality offset value, Qoffset temp Indicates the access temporary offset.
[0095] In addition, in the situations described in 4.1 and 4.2, if more than one cell meets the above cell reselection related conditions, the terminal should select a 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 that frequency;
[0097] If the highest priority frequency is a frequency of another RAT, reselect to the strongest cell on that frequency that meets the reselection criteria for that RAT.
[0098] 4.3 R Criterion
[0099] The terminal uses the R criterion to sort the serving cell and candidate neighboring cells in order to determine and reselect the optimal cell.
[0100] The R criterion determines the parameters (R) on which the cell ranking is based through the following two expressions: s 、R n ):
[0101] For serving cells: R s =Q meas,s +Q hyst-Qoffset temp
[0102] For neighboring areas: R n =Q meas,n -Qoffset-Qoffset temp
[0103] Among them, Q meas,s , Q meas,n Indicates the level value or signal strength (RSPR) measurement quantity used in cell reselections; Qoffset temp Indicates 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 If valid, equal to Qoffset s,n , otherwise it is equal to 0;
[0105] For inter-frequency: If the cell-specific parameter Qoffset s,n If valid, equal to Qoffset s,n +Frequency-specific parameter Qoffset frequency , otherwise equal to Qoffset frequency .
[0106] In the related art, for a UE that supports a wake-up signal, the wake-up signal may only be used in a specific cell of the UE (such as the last used cell). When the UE leaves the specific cell, the UE cannot use the wake-up signal, resulting in very limited power saving gains for the UE. Especially when the UE has high power saving requirements, how to enable the UE to enjoy the power saving gains of the wake-up signal as much as possible is an issue that needs to be considered urgently.
[0107] The present application provides a cell processing method, apparatus, terminal, network-side device, and readable storage medium, which enable the terminal to enjoy as much power saving gain as possible by using a wake-up signal.
[0108] The cell processing method, apparatus, terminal, network-side equipment, and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.
[0109] For ease of description, the following unified description of the various terms involved in the embodiments of this application is first provided. (Unless otherwise specified, the following unified description of the various terms applies to all embodiments of this application. Due to the fact that some individual terms first appear later, they will not be uniformly described here. Below, they will be described when they first appear.)
[0110] Network side device: It can be the network side device 12 in Figure 1. For examples of the network side device 12, please refer to the previous text and will not be repeated here.
[0111] Terminal: It can be the terminal 11 in FIG1 . For an example of the terminal 11 , please refer to the above text and will not be described in detail here.
[0112] Cell priority: The cell selection priority or cell reselection priority of the cell.
[0113] Frequency priority of the cell: the cell selection priority or cell reselection priority of the frequency where the cell is located, that is, the cell selection priority or cell reselection priority of all cells at the frequency where the cell is located.
[0114] In a first aspect of an embodiment of the present application, a cell processing method is provided. The method is executed by a terminal. Referring to FIG2 , which is a flowchart of an implementation of a cell processing method provided in an embodiment of the present application, the method may include the following steps:
[0115] Step S101: The terminal performs 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 residing, and the target cell is: the cell which receives the radio resource control release message for the last time.
[0118] The first priority information is used to represent at least one of the following:
[0119] The target cell of the terminal has the highest priority;
[0120] The frequency point where the target cell of the terminal is located has the highest priority;
[0121] The terminal satisfies at least one of the following:
[0122] Support monitoring wake-up signals;
[0123] Configured to listen for wake-up signals.
[0124] It should be noted that the activation of the non-last used cell (i.e., non-target cell) of the terminal indicates that the wake-up signal is sent only in the last used cell, or the non-last used cell does not have the configuration information of sending a wake-up signal or broadcasting a wake-up signal, then the cell reselection priority of the non-last used cell is the lowest; or lower than the last used cell.
[0125] In a 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, the priority of the last used cell is set to the highest or considered to be the highest (corresponding to the protocol agreement) according to the first priority information, or the priority of the frequency point where the last used cell is located is set to the highest or considered to be the highest, that is, the priority of all cells (including the last used cell) at the frequency point where the last used cell is located is set to the highest or considered to be the highest. This can greatly increase the probability that the new resident cell selected by the terminal for performing cell selection or cell reselection is the last used cell, thereby increasing the possibility of supporting 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.
[0126] When the second cell in which the terminal is currently located is not the last used cell of the terminal, and the second cell restricts that only terminals whose last used cell is 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 last used cell of the terminal so as to use the wake-up signal in the second cell in which the terminal is currently located, so that the terminal can enjoy the power saving gain of the wake-up signal as much as possible.
[0127] For example, the terminal may switch itself from an idle state to a connected state, and request the network-side device to send an RRC release message in the second cell, thereby updating the second cell as the last used cell of the terminal.
[0128] It can be seen from the above steps that the method of updating the last used cell of the UE to the currently resident cell, or adjusting the relevant priority of the last used cell in the cell selection or cell reselection to the highest, so as to increase the possibility of the last used cell being determined as the new resident cell in the cell selection or cell reselection, can greatly increase the possibility that the current resident cell or the new resident cell of the terminal supports the terminal to use the wake-up signal, thereby enabling the terminal to enjoy as much power saving gain as possible by using the wake-up signal.
[0129] In some implementations, the target cell of the terminal satisfies at least one of the following:
[0130] A wake-up signal was sent;
[0131] Broadcast the configuration information of the wake-up signal;
[0132] 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 implementations, the terminal further performs cell selection or cell reselection according to the second priority information, where the second priority information is used to represent at least one of the following:
[0134] The first cell has the highest or second highest priority;
[0135] The frequency point where the first cell is located has the highest or second highest priority;
[0136] 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 sends a wake-up signal or broadcasts the 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 the two as the cell with the highest priority.
[0138] In a specific implementation, considering that in the cell that sends 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), the terminal (i.e., the terminal whose last used cell is not the first cell) can also be supported to use the wake-up signal. In this embodiment, the priority of the first cell is set to the highest (or second highest) by means of the second priority information, or the terminal considers it to be the highest (or second highest), or the priority of the frequency point where the first cell is located is set to the highest (or second highest), or the terminal considers it to be the highest (or second highest), that is, the priority of all cells (including the first cell) at the frequency point where the first cell is located is set to the highest (or second highest), or the terminal considers it to be the highest (or second highest), and the terminal will then give priority (or second priority) to the first cell with the highest (or second highest) priority. Stay, thereby further improving the possibility that the new stay cell selected by the terminal for performing 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 comprises at least one of the following:
[0140] The terminal receives a control message such as an RRC release message or an RRC reject message carrying at least one of the first priority information and the second priority information;
[0141] The terminal receives a broadcast message such as a system information block (SIB) carrying at least one of the first priority information and the second priority information.
[0142] In some implementations, the first priority information or the second priority information is valid before a first timer expires, and the method further includes:
[0143] When the terminal receives a control message carrying at least one of the first priority information or the second priority information, the terminal starts or restarts the first timer.
[0144] In a specific implementation, a timer (i.e., a first timer) is configured for the terminal. When the terminal receives a control message (or 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 that the cell reselection priority of the UE's last used cell and the cell reselection priority of the first cell indicated by at least one of the first priority information and the second priority information are valid. By introducing the first timer to set a validity period for the cell reselection priority configured for 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 implementations, when the terminal receives a control message, and the control message carries at least 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 performing cell selection or cell reselection according to at least one of the first priority information and the second priority information, the terminal updates the stored priority information of the first cell according to the second priority information when receiving a broadcast message carrying the second priority information from the currently resident cell.
[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 based on the stored priority information of the first cell.
[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 resolving 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 current resident cell (that is, the terminal receives a broadcast message carrying the second priority information from the current 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, so as to ensure the reliability and comprehensiveness of the priority information of the first cell stored by the terminal.
[0151] Optionally, the network side device broadcasts the priority information of the first cell in the new current resident cell, and the control message most recently received by the terminal does not carry the priority information of the first cell (or the carried priority information of the first cell has expired), then the terminal updates the stored priority information of the first cell based on the broadcast second priority information to further ensure the reliability of the priority information of the first cell stored in the terminal.
[0152] In some implementations, when there are multiple rules for determining the cell or frequency 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 rule agreed upon in the protocol;
[0154] The terminal determines the target rule by itself;
[0155] The target rule is a rule that specifies the cell or frequency with the highest priority.
[0156] In specific implementation, considering that the determination of priority is related to multiple characteristics (i.e., multiple rules), there is a situation where the protocol agreement or the network side device indicates that the UE believes that multiple cells or frequencies have the highest priority. At this time, the terminal can determine the target rule based on the protocol agreement or determine it by itself or the network side device configures the target rule. The terminal can then determine the cell or frequency with the highest priority based on the target rule, thereby resolving the conflict of the highest priority.
[0157] For example, when the UE supports vehicle to X (V2X) or NR sidelink, or the UE supports high-speed data network (HSDN), and the UE supports wake-up signals, the UE considers, according to the protocol, the HSDN cell and the frequency points providing NR sidelink and V2X sidelink communication configurations as the highest priority. However, it is impossible for multiple types of cells to be the highest priority cells at the same time. At this time, the protocol can be agreed to allow the UE to consider the HSDN cell as the cell with the highest cell reselection priority, or the protocol can be agreed to allow the UE to consider the frequency points providing NR sidelink and V2X sidelink communication configurations as 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 the UE implementation can determine which feature-related frequency point is the highest priority frequency point (corresponding to the case where the terminal determines the target rule itself).
[0158] In some implementations, the terminal performs cell selection or cell reselection according to at least one of the first priority information and the second priority information. Depending on the 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 based on the frequency granularity.
[0160] In case 1, the first priority information or the second priority information can adjust the priority at the frequency granularity, that is, the first priority information can be used to indicate that the frequency of the last used cell has the highest priority, and the second priority information can be used to indicate that the frequency of the first cell 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 UE's last used cell or the first cell is located as the highest priority frequency point. 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 reside in the cell under the highest priority frequency point (such as the UE's last used cell or the first cell).
[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 to set the frequency point where the UE's last used cell is located as the highest priority frequency point, and send the second priority information to set the frequency point where the first cell is located as the second highest priority frequency point. 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 give priority to residing in the cell with the highest priority frequency point (such as the UE's last used cell), and secondly give priority to residing in the cell with the second highest priority frequency point (such as the first cell).
[0163] Case 2: Priority is adjusted 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 last used cell has the highest priority, and the second priority information can indicate that the first cell has the highest or second highest priority.
[0165] For example, the network side device can use a control message (or broadcast message) to send the first priority information to the terminal to set the UE's last used cell as the highest priority cell; or send second priority information to the terminal to set the first cell as the highest priority cell. 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 reside in the UE's last used cell 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 UE's last used cell 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 give priority to residing in the last used cell of the UE, and secondly give priority to residing in 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: first indication information, used to indicate whether the first cell has the highest or second highest priority;
[0169] Item A-2: second indication information, used to indicate that the target cell of the terminal has the highest priority;
[0170] Item A-3: third indication information, used to indicate whether the frequency point where the first cell is located has the highest or second highest priority;
[0171] Item A-4: fourth indication information, used to indicate that the frequency point where the target cell of the terminal is located has the highest priority;
[0172] Item A-5: Identification information of the first cell.
[0173] Item A-1 needs to be used in conjunction 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 (ie, directly indicates) that the first cell has the highest or second highest priority.
[0174] For item A-2, the network side device may use a control message (or a broadcast message) to send second indication information (such as a bit or bit string of a specific value) to the terminal to indicate that the last used cell of the terminal has the highest priority.
[0175] Item A-3 needs to be used in conjunction 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 frequency point where the first cell is located has the highest or second highest priority.
[0176] For item A-4, the network side device can use a control message (or broadcast message) to send fourth indication information (such as a bit or bit string of a specific value) to the terminal to indicate that the frequency point where the last used cell of the terminal is located has the highest priority.
[0177] For item A-5, it can be agreed in advance that after receiving the identification information of a certain cell, the terminal will determine the cell as the first cell and set the priority of the first cell to the highest or second highest. The network side device can then send 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 point where the first cell is located) is the highest or second highest.
[0178] Optionally, the network side device may also send identification information of the first cell to the terminal, indicating that the last used cell of the terminal has the highest priority.
[0179] In some embodiments, considering that the combination of frequency and cell identifier can uniquely identify a cell, the identification information of the first cell may include the frequency of the first cell and the physical cell identifier (PCI) of the first cell.
[0180] For example, after receiving the identification information including the frequency and PCI, the terminal can know that the cell identified by the frequency and PCI can allow the UE whose last used cell is not the cell to use the wake-up signal (that is, determine that the cell is the first cell). When the UE performs cell selection or reselection, it will consider the last used cell as the cell with the highest cell reselection priority, and consider the cell as the cell with the highest or 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 messages;
[0183] Broadcast messages;
[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 it can 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, wherein the cell reselection configuration information can be carried by a control message or a broadcast message.
[0186] Taking the example that the identification information of the first cell includes the PCI of the first cell and the frequency where the first cell is located, the network side device can carry the PCI of the first cell through the configuration information of the frequency 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 where the first cell is located based on the PCI carried by the configuration information and the frequency where the configuration information is located, thereby realizing the carrying of the identification information of the first cell through the configuration information of the frequency where the first cell is located in the cell reselection configuration information.
[0187] The implementation of Case 2 is further illustrated below through Examples 1 to 3.
[0188] Example 1: The network-side device includes 1 bit of indication information (i.e., second indication information) in the RRC release message to instruct the UE to set the UE's last used cell as the cell with the highest priority, and includes one or more frequencies and PCIs (i.e., identification information of the first cell) of the first cell in the RRC release message or 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 frequency and PCI (or other cell identifier) of one or more first cells in the RRC release message or SIB to directly indicate which cells are the first cells and the priority of the first cells is the second highest priority, and implicitly indicates that the last used cell of the UE is the cell with the highest priority.
[0190] Example 3: The network-side device includes the frequencies and PCIs (i.e., identification information of the first cells) of multiple first cells in the RRC release message or SIB, and may also include corresponding PCIs in the configuration information of the frequencies of the multiple first cells in the cell reselection configuration information in the RRC release message, so as to indicate which cells in the cell list included in the frequency are the first cells, and in a manner agreed upon by the protocol, make the UE consider the cell reselection priority of the first cell as the second highest priority, and at the same time consider the last used cell of the UE as the cell with the highest cell reselection priority.
[0191] In some implementations, the protocol stipulates or the network side device configures (or sends) the first parameter or the second parameter. For example, the network side device may carry the first parameter or the second parameter in a control message or a broadcast message to send to the terminal.
[0192] The first parameter is used to increase the probability that the terminal selects the last used cell of the terminal for resident, and the second parameter is used to increase the probability that the terminal selects the first cell for resident, which may specifically include the following four situations.
[0193] Case 1: The terminal calculates a ranking reference value of a serving cell associated with a target cell of the terminal based on a first parameter.
[0194] In case 1, when the UE's current camping cell is the last used cell, the terminal can use R s The sum of the first parameter (which can be understood as an offset value, the offset value is greater than 0) is determined as the ranking reference value of the serving cell associated with the last used cell, so as to optimize the position of the last used cell in the cell ranking (which is determined by the size of the ranking reference value) and increase the probability that the terminal selects the last used cell of the terminal for residence.
[0195] Case 2: The terminal calculates a ranking reference value of neighboring cells associated with the target cell of the terminal based on the first parameter.
[0196] In case 2, when the UE's current camping cell is not the last used cell, the terminal can use R n The sum of the first parameter is determined as a ranking reference value of the neighboring cell associated with the last used cell, so as to improve the probability that the terminal selects the last used cell of the terminal for resident by optimizing the position of the last used cell in the cell ranking.
[0197] Case 3: The terminal calculates a ranking reference value of the serving cell associated with the first cell based on the second parameter.
[0198] In case 3, when the UE's current camping cell is the first cell, the terminal can select R s The sum of the first parameter and the second parameter (which can be understood as an offset value, the offset value is greater than 0) is determined as the ranking reference value of the service cell associated with the first cell, so as to improve the probability of the terminal choosing to reside in the first cell by optimizing the position of the first cell in the cell ranking.
[0199] Case 4: The terminal calculates a ranking reference value of neighboring cells associated with the first cell based on the second parameter.
[0200] In case 4, when the UE's current camping cell is not the first cell, the terminal can select R n The sum of the first parameter and the second parameter is determined as a ranking reference value of neighboring cells associated with the first cell, so as to improve the probability that the terminal chooses to reside in the first cell by optimizing the position of the first cell in the cell ranking.
[0201] In some embodiments, the first parameter and the second parameter may be the same or different parameters.
[0202] It should be noted that, for the serving cell and the neighboring cell without the introduction of the first parameter and the second parameter, the ranking reference value of the serving cell and the neighboring cell can be R s and R n , R s and R n The definition of can refer to the previous description of the R criterion and will not be repeated here.
[0203] In some implementations, 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, thereby avoiding frequent updates of the last used cell.
[0204] Specifically, when the first condition is met, the terminal sends first information to the network side device in the second cell where the terminal is currently residing, where the first information 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 residing;
[0205] The first condition includes one or more of the following:
[0206] Item B-1: The duration for which the terminal resides in the second cell is greater than a first threshold;
[0207] B-2: The second timer times out;
[0208] Item B-3: The mobility of the terminal is lower than the 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 times the terminal is paged before the second timer expires exceeds a third threshold;
[0211] Item B-6: Since the terminal camped on the second cell, the number of times the terminal has been paged exceeds a fourth threshold;
[0212] Item B-7: Since the terminal camps on 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 sends a wake-up signal or configures 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] Items B-1 to B-3 are mainly used to measure whether the terminal will stay in the second cell for a long time. By updating the last used cell of the terminal that stays 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 in the second cell as much as possible.
[0216] Items B-4 to B-7 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, the frequent update of the last used cell of the terminal can be avoided, and the probability of the terminal (or other terminals that monitor a PO together with the terminal) being mistakenly awakened due to not using the wake-up signal can be greatly reduced, thereby enabling the terminal to enjoy the power-saving gain of the wake-up signal in the second cell as much as possible.
[0217] Items B-8 and B-9 are mainly used to determine whether the UE's last used cell needs to be updated to the second cell so that the terminal can use the wake-up signal in the second cell, thereby enabling the terminal to enjoy the power saving gain of the wake-up signal in the second cell as much as possible.
[0218] In some embodiments, a configuration method for one or more parameters of 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] Use RRC release message configuration, for example, the network side device can configure one or more of the above parameters specific to the UE in the RRC release message according to the characteristics of the UE;
[0220] As agreed in the agreement;
[0221] The second cell broadcasts, for example, the second cell broadcasts how long the UE has been stationed in the current cell (corresponding to the first threshold) before requesting to update the last used cell to the current cell, or the second cell broadcasts how high the UE's paging probability (corresponding to the second threshold) is before requesting to update the last used cell to the current cell, etc.
[0222] Carried in Non-Access Stratum (NAS) messages;
[0223] The terminal and the network device negotiate and determine, for example, the UE sends its desired first threshold value or first timer duration and other parameters in a Registration Request message, and the network device returns the final determined first threshold value or first timer duration and other parameters to the UE in a Registration Accept message;
[0224] The terminal determines the above one or more parameters by itself, such as the terminal determines the above one or more parameters based on its own preference or implementation.
[0225] In some embodiments, when multiple configuration methods are used to configure one or more of the above parameters, the configuration method to be adopted can be determined based on the priority of each configuration method agreed upon in the protocol.
[0226] In some embodiments, the method further comprises:
[0227] When receiving the configuration information of the duration of the second timer, the terminal starts the second timer.
[0228] In a specific implementation, the terminal determines the moment when the configuration information of the duration of the second timer is received as the moment when the second timer is started. The moment when the configuration information of the duration of the second timer is received may include the frame, subframe, time slot, OFDM symbol or minute (m), millisecond (ms), etc. where the configuration information is located.
[0229] In some embodiments, the first information is used to represent 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 a power saving mechanism;
[0232] The paging frequency of the terminal 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 facilitates the network-side device to reasonably determine whether to update the last used cell of the terminal based on whether the power saving requirement of the terminal is high;
[0234] The power consumption level of the terminal facilitates the network-side device to reasonably determine whether to update the last used cell of the terminal based on whether the power consumption level of the terminal is high;
[0235] The paging probability of the terminal 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] A non-access layer NAS message, for example, the network side device may carry the first information through a message for performing location area update (such as a Registration request message);
[0238] User experience assistance information (UAI);
[0239] Radio Resource Control Recovery Complete (RRCResumeComplete) message;
[0240] A radio resource control setup request (RRCSetupRequest) message, used to indicate that the reason for the terminal to establish a connection is to update the last used cell of the terminal;
[0241] The radio resource control resumption request (RRCResumeRequest) message is used to indicate that the reason for the terminal to resume connection is to update the target cell of the terminal.
[0242] In a second aspect of the embodiments of the present application, another cell processing method is provided. The method is performed by a network-side device. Referring to FIG3 , which is a flowchart of an implementation of another cell processing method provided in an embodiment of the present application, the 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 currently resides, and the target cell is: the cell that receives the radio resource control release message for the last time.
[0246] The first priority information is used to represent at least one of the following:
[0247] The target cell of the terminal has the highest priority;
[0248] The frequency point where the target cell of the terminal is located has the highest priority;
[0249] The terminal satisfies at least one of the following:
[0250] Support monitoring wake-up signals;
[0251] Configured to listen for wake-up signals.
[0252] It can be seen from the above steps that the method of updating the last used cell of the UE to the currently resident cell, or adjusting the relevant priority of the last used cell in the cell selection or cell reselection to the highest, so as to increase the possibility of the last used cell being determined as the new resident cell in the cell selection or cell reselection, can greatly increase the possibility that the current resident cell or the new resident cell of the terminal supports the terminal to use the wake-up signal, thereby enabling the terminal to enjoy as much power saving gain as possible by using the wake-up signal.
[0253] In some implementations, the target cell of the terminal satisfies at least one of the following:
[0254] A wake-up signal was sent;
[0255] Broadcast the configuration information of the wake-up signal;
[0256] 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 implementations, the network-side device further sends second priority information to the terminal, where the second priority information is further used to represent at least one of the following:
[0258] The first cell has the highest or second highest priority;
[0259] The frequency point where the first cell is located has the highest or second highest priority;
[0260] The cell identifier of the first cell is different from the cell identifier of the last used cell of the terminal, and the first cell satisfies: the first cell sends a wake-up signal or broadcasts configuration information of the wake-up signal, and the first cell does not indicate that only the terminal whose last used cell is the first cell can use the wake-up signal in the first cell.

[0264] In some embodiments, the first priority information or the second priority information is valid before a first timer expires, and the first timer is started or restarted 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 comprises:
[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 new camping cell of the terminal.
[0267] In some embodiments, the first priority information or the second priority information includes at least one of the following:
[0268] First indication information, used to indicate whether the first cell has the highest or second highest priority;
[0269] The second indication information is used to indicate that the last used cell of the terminal has the highest priority;
[0270] The third indication information is used to indicate whether the frequency point where the first cell is located has the highest or second highest priority;
[0271] Fourth indication information, used to indicate that the frequency point where the target cell of the terminal is located has the highest priority;
[0272] Identification information of the first cell.
[0273] In some implementations, the identification information of the first cell is carried by at least one of the following:
[0274] Control messages;
[0275] Broadcast messages;
[0276] Configuration information of the frequency point where the first cell is located in the cell reselection configuration information.
[0277] In some embodiments, the method further comprises at least one of the following:
[0278] The network-side device sends a first parameter to the terminal, where the first parameter is used to increase a probability that the terminal selects the last used cell of the terminal for resident;
[0279] The network-side device sends a second parameter to the terminal, where the second parameter is used to increase the probability that the terminal chooses to reside in 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 control messages;
[0282] Carried in broadcast messages.
[0283] In some implementations, 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 residing, where 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 residing;
[0285] The first condition includes one or more of the following:
