Description

Cell residency method and device

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on April 1, 2024, with application number 202410385726.5 and application name “Cell Residency Method and Device,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a cell camping method and device. Background Art

[0003] To reduce network energy consumption, a network-side energy-saving mechanism has been introduced into wireless communication systems. The Network Energy Saving (NES) technology in R19 introduces an on-demand SIB1 mechanism. Specifically, the network does not send SIB1 messages in energy-saving mode. It only sends SIB1 messages to a base station when there is a demand, such as a request from a UE or a neighboring base station. However, in related technologies, NES UEs cannot reside in an on-demand SIB1 cell, resulting in the need to perform measurements and other procedures when initiating the radio resource control (RRC) connection establishment process due to the arrival of services, resulting in additional delays. Summary of the Invention

[0114] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0115] The terms "first," "second," and the like in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein may be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products, or apparatus.

[0116] In the embodiments of the present disclosure, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship. In the embodiments of the present disclosure, the term "plurality" refers to two or more, and other quantifiers are similar.

[0117] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0118] Figure 1 shows a block diagram of a wireless communication system to which the embodiments of the present disclosure can be applied. The wireless communication system includes a terminal device 11 and a network-side device (or network device) 12. The terminal device 11 may also be referred to as a terminal or a user equipment (UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present disclosure. The network-side device 12 may be a base station or a core network. It should be noted that in the embodiments of the present disclosure, only a base station in the NR system is used as an example, but the specific type of the base station is not limited.

[0119] In order to enable those skilled in the art to better understand the embodiments of the present disclosure, the following description is first given.

[0120] 1. Function of Synchronization Signal / PBCH (SSB);

[0121] The SSB contains basic base station synchronization information. The UE obtains basic synchronization information and downlink (DL) channel quality by measuring the SSB. SSB information is sent periodically and can be repeated within a certain period.

[0122] 2. Function of System Information Block 1 (SIB1);

[0123] In related technologies, a cell always sends a SIB1 message, which contains basic information that allows a UE to access the cell, such as the Public Land Mobile Network (PLMN), access control information, and Random Access Channel (RACH) configuration information. The SIB1 message is sent repeatedly at a certain period.

[0124] 3. Basic concepts of on-demand SIB1 scenarios in related technologies;

[0125] The network always sends SIB1 messages at a predetermined interval. SIB1 messages contain basic information that allows a UE to access a cell, such as the PLMN and random access (RA) configuration. To save energy on the network side, the base station can disable the transmission of SIB1 messages. This also prevents the UE from staying in the cell, impacting cell coverage and network capacity.

[0126] When the UE is in idle / inactive state, if a cell is in energy-saving state and no SIB1 message is sent, but the UE detects this cell based on the cell's SSB information and wants to access the cell, the cell needs to start SIB1 transmission based on a certain trigger mechanism so that the UE can reside in the corresponding cell.

[0127] 4. Cell selection / reselection mechanism;

[0128] When a UE performs cell selection and reselection, the basic principle is to select a suitable cell according to the cell selection or reselection mechanism, such as the cell with the highest frequency priority and the best channel quality, and read the access control information in the Master Information Block (MIB) and / or Unified Access Control (UAC) in the SIB message of the cell, or the cell access allowed (not barred) or prohibited access (cell barred) indication information. If the UE is allowed to access, the UE can camp on this cell and monitor the paging messages sent by this cell. If the UE cannot read the SIB1 information, the UE will not camp on this cell and will not perform the cell selection or reselection process for this cell within the limited time.

[0129] The cell camping method provided by the embodiment of the present disclosure is described in detail below with reference to some embodiments and application scenarios in conjunction with the accompanying drawings.

[0130] As shown in FIG2 , an embodiment of the present disclosure provides a cell camping method, which is executed by a terminal and includes:

[0131] Step 201: When the terminal determines that a cell is a cell that sends system information block SIB1 on demand and the acquired first indication information indicates that the network energy-saving terminal is allowed to access the cell, the cell is used as a candidate cell for cell selection or reselection.

[0132] Through the above solution, the network energy-saving terminal can reside in the on-demand SIB1 cell, and then can monitor paging messages and access the on-demand SIB1 cell without having to perform cell measurement on the on-demand SIB1 cell, thereby effectively reducing the delay during service access.

[0133] In some embodiments, the above-mentioned alternative cells may be described as candidate cells.

[0134] In some embodiments, the first indication information is sent by the cell or by a neighboring cell of the cell, or the first indication information is obtained according to a SIB message of the cell historically stored in the terminal.

[0135] In some embodiments, the first indication information allowing the network energy-saving terminal to access the cell can be understood as: the first indication information of the cell indicates that the network energy-saving terminal is allowed to access the cell, and the cell status is indicated as not being reserved for the operator, and is not true for other situations and is not true for future situations. Optionally, the cell is selected as a candidate cell for cell selection and / or reselection.

[0136] Alternatively, at least the first indication information of the cell indicates that the network energy-saving terminal is allowed to access the cell. Here, allowing the network energy-saving terminal to access the cell means not prohibiting the network energy-saving terminal from accessing the cell.

[0137] In some embodiments, the terminal is a terminal supporting Network Energy Saving (NES) capability;

[0138] The NES capability may at least include the capability of residing in a cell that sends SIB1 on demand and / or the capability of acquiring SIB1 of a cell that sends SIB1 on demand.

[0139] In some embodiments, the NES capability is an optional capability or a mandatory capability of R19 UE.

[0140] In some embodiments, the network energy-saving terminal has at least one of the following network energy-saving terminal characteristics (which may also be described as R19 NES UE characteristics):

[0141] Supports the feature of selecting, reselecting or residing on a cell that sends SIB1 on demand;

[0142] Ability to obtain the feature of sending SIB1 information of SIB1 cells on demand.

[0143] Since the network energy-saving terminal supports the characteristics of selecting, reselecting or residing in the on-demand SIB1 cell and / or can obtain the SIB1 information of the on-demand SIB1 cell, the first indication information obtained allows the network energy-saving terminal to access the on-demand system information block SIB1 cell, and the cell can be used as an alternative cell for cell selection or reselection, so as to facilitate subsequent residency in the on-demand SIB1 cell.

[0144] In some embodiments, the network energy-saving terminal feature also includes a feature of establishing a radio resource control RRC connection with a synchronization broadcast block SSB-less cell.

[0145] Here, when the network energy-saving terminal characteristic also includes the characteristic of establishing a radio resource control RRC connection with an SSB-less cell, the network energy-saving terminal can not only reside in the on-demand SIB1 cell, but also establish an RRC connection with the SSB-less cell.

[0146] In some embodiments, the candidate cell may be described as a candidate cell. Here, if the terminal determines that a cell is a SIB1-based cell and the first indication information obtained indicates that the network energy-saving terminal is allowed to access the cell, the cell is selected as a candidate cell for cell selection or reselection, so as to facilitate subsequent resident access to the SIB1-based cell.

[0147] Terminals that do not have NES capabilities, or do not support camping on an on-demand SIB1 cell, or do not have the ability to trigger the on-demand SIB1 cell to send SIB1 messages, or cannot identify the cell as an on-demand SIB1 cell, cannot use the on-demand SIB1 cell as a candidate cell for cell selection or reselection, and therefore cannot camp on the on-demand SIB1 cell.

[0148] In the above solution, if the idle or inactive terminal supports NES capability and can identify the cell as an on-demand SIB1 cell, it can still camp on the on-demand SIB1 cell and monitor paging messages even if SIB1 information cannot be detected at the moment.

[0149] In the disclosed embodiment, when a terminal determines that a cell is an on-demand SIB1 cell and the obtained first indication information indicates that the network energy-saving terminal is allowed to access the cell, the cell is selected as a candidate cell for cell selection or reselection. This solution enables the network energy-saving terminal to reside on the on-demand SIB1 cell and subsequently monitor paging messages and access the on-demand SIB1 cell without having to perform cell measurements on the on-demand SIB1 cell, thereby effectively reducing service access latency.

[0150] In some embodiments, the method of the present disclosure further includes:

[0151] In the case of camping on the on-demand SIB1 cell, a paging message sent by the on-demand SIB1 cell is obtained, or a paging message sent by a neighboring cell of the on-demand SIB1 cell is obtained.

[0152] As an implementation method, the terminal may periodically go to a neighboring cell to obtain paging messages.

[0153] By acquiring the paging message, the on-demand SIB1 cell can be accessed.

[0154] In some embodiments, the method of the embodiments of the present disclosure further includes at least one of the following:

[0155] Item 1: When the SIB of the neighboring cell of the cell includes the wake-up signal (WUS) configuration information corresponding to the cell, it is determined that the cell is a cell that sends SIB1 on demand, and the wake-up signal is used to trigger the cell to send SIB1.

[0156] In the disclosed embodiment, the WUS configuration information and associated cell information in the SIB of the neighboring cell can be obtained based on the historical information stored in the terminal, or the WUS configuration information related to the cell of the on-demand system information block SIB1 can be obtained by reading the system message SIB of the cell, for example, the mapping relationship between the WUS configuration information and the cell.

[0157] Item 2: When the terminal stores the SIB1 of the cell, determining that the cell is a cell that sends SIB1 on demand, wherein the stored SIB1 is triggered by the terminal through wake-up signal configuration information to send the cell or to trigger a neighboring cell of the cell to send.

[0158] The SIB1 may be obtained by sending a WUS when the terminal historically resides in the cell.

[0159] Item 3: When the Master Information Block (MIB) of the cell indicates that the SSB parameter of the synchronized broadcast block is a preset parameter, the cell is determined to be a cell that sends SIB1 on demand, and the SSB parameter includes at least one of the SSB sending period, SSB sending frequency and SSB sequence information, and the preset parameter is the SSB parameter corresponding to the cell that sends SIB1 on demand.

[0160] Here, whether the cell is a cell that sends system information blocks SIB1 on demand is implicitly determined by parameters such as the SSB transmission period, SSB transmission frequency, and SSB sequence information.

[0161] Of course, the above-mentioned SSB parameters may also include other parameters of SSB, which are not specifically limited here.

[0162] Item 4: When the master information block of the cell includes second indication information, determining that the cell is a cell that sends SIB1 on demand, and the second indication information is used to indicate that the cell is a cell that sends SIB1 on demand.

[0163] Here, whether the cell is a cell that sends SIB1 on demand is explicitly determined through the second indication information included in the MIB.

[0164] It can be understood that in this embodiment, when the terminal determines that the cell is a cell that sends the system information block SIB1 on demand, and the first indication information obtained indicates that the network energy-saving terminal is allowed to access the cell, before using the cell as an alternative cell for cell selection or reselection, the cell can be determined to be a cell that sends SIB1 on demand. The step of determining that the cell is a cell that sends SIB1 on demand may include at least one of the above-mentioned first, second, third and fourth items.

[0165] In some embodiments, the method of the present disclosure further includes:

[0166] The first indication information is acquired according to at least one of the MIB and SIB1 of the cell.

[0167] For example, the first indication information may be cell access control information in the MIB or SIB, or may be indication information newly added in the MIB or SIB1 for indicating whether to allow or prohibit the network energy-saving terminal from accessing the on-demand SIB1 cell.

[0168] It can be understood that in this embodiment, when the terminal determines that the cell is a cell that sends system information block SIB1 on demand, and the first indication information obtained indicates that the network energy-saving terminal is allowed to access the cell, before using the cell as an alternative cell for cell selection or reselection, the first indication information can be obtained. The step of obtaining the first indication information may include the above-mentioned embodiment.

[0169] In some embodiments, the method of the present disclosure further includes:

[0170] Obtain third indication information, where the third indication information is used to indicate that SIB1 of the cell is updated;

[0171] According to the third indication information, the updated SIB1 is received through a pre-agreed or network-configured period.

[0172] In the embodiment of the present disclosure, when the SIB1 of the on-demand SIB1 cell is updated, the on-demand SIB1 cell notifies the UE that its SIB1 message has been updated, and the UE receives the updated SIB1 through a pre-agreed or network-configured period, so that it can reside in the cell according to the updated SIB1.

[0173] As an implementation manner, obtaining the third indication information includes:

[0174] The third indication information is obtained through a shared channel or a control channel of the paging message.

[0175] Here, the shared channel or control channel based on the paging message notifies that the SIB1 is updated, so that when the terminal accesses the cell based on the paging message, it can access the cell based on the latest SIB1.

[0176] In the disclosed embodiment, when a terminal determines that a cell is an on-demand SIB1 cell and the obtained first indication information indicates that the network energy-saving terminal is allowed to access the cell, the cell is selected as a candidate cell for cell selection or reselection. This solution enables the network energy-saving terminal to reside on the on-demand SIB1 cell and subsequently monitor paging messages and access the on-demand SIB1 cell without having to perform cell measurements on the on-demand SIB1 cell, thereby effectively reducing service access latency.

[0177] The cell camping method disclosed in the present invention is described below with reference to embodiments.

[0178] Example 1: Inactive / Idle UE camps on the NES cell;

[0179] As shown in Figure 3, it includes:

[0180] Step 0: The network side sends a SIB1 message.

[0181] This step 0 is an optional step.

[0182] Step 1: The UE attempts to read the MIB and / or SIB1 information of the cell. If the UE supports the NES capability and can identify the cell as an on-demand SIB1 cell, and the indication information in the MIB or SIB1 allows the UE to access, the UE uses the cell as a candidate cell for cell selection / reselection. The UE selects the cell to camp on through the cell selection and reselection process.

[0183] The UE may obtain the MIB and / or SIB1 sent by the cell, or may obtain the MIB and / or SIB1 of the cell based on historical information stored in the terminal.

[0184] In some embodiments, the terminal may identify whether the cell is an on-demand SIB1 cell by:

[0185] Method 1: Determine that the cell is an NES on-demand cell (i.e., on-demand SIB1 cell) based on stored historical information, such as the WUS configuration and cell information broadcast in the SIB of the stored neighboring cell.

[0186] Method 2: Determine whether the cell is an NES on-demand cell based on the SIB1 obtained by initiating WUS during historical residency.

[0187] Specifically, when the history resides in the cell, the terminal initiates a WUS to trigger the cell to send SIB1, and the terminal obtains and stores the SIB1.

[0188] Method 3: Read the system information SIBx of the neighboring cell, obtain the SIB1 information of the NES cell from the SIBx of the neighboring cell, such as the mapping relationship between the WUS configuration and the cell, and determine that the cell is an on-demand SIB1 cell;

[0189] Method 4: Based on the SSB transmission period, frequency, and sequence information in the MIB message of the NES cell, the cell is explicitly or implicitly indicated as an on-demand SIB1 cell.

[0190] Method 5: The MIB message of the NES cell includes an indication information, which is used to indicate whether the cell is an on-demand SIB1 cell.

[0191] It should be noted that UEs that do not have NES capabilities, or do not support camping on an on-demand SIB1 cell, or do not have the capability to trigger an on-demand SIB1 cell to send a SIB1 message, or cannot identify the cell as an on-demand SIB1 cell, cannot camp on this cell.

[0192] Here, the specific meaning of the indication information in MIB or SIB1 that allows UE access is:

[0193] The message in the MIB or SIB1 includes indication information (i.e., first indication information) for allowing or prohibiting access to a cell with R19 NES UE characteristics. Specifically, indication information for allowing access or indication information for prohibiting access related to the R19 NES UE characteristics appears. The indication information can be expressed in an explicit or implicit manner. The indication information may include one or more bits or variables, and each bit (bit) / variable corresponds to one or more characteristics. The R19 NES UE characteristics include on-demand SIB1 characteristics, SSB-less cell characteristics, common channel or signal adaptation characteristics, or one or a combination of other characteristics. The specific meaning of the on-demand SIB1 characteristic may be that the UE can use the UL signal to trigger the network to send SIB messages for NES cells that do not send SIB1. Supporting the SSB-less cell characteristic may mean that the UE can maintain connection to a cell that sends SSB in an energy-saving mode.

[0194] Step 2: After the UE camps on the cell, it reads the paging message sent by the cell, or the UE chooses to camp on the cell and periodically obtains the paging messages sent by neighboring cells.

[0195] It should be noted that the above-mentioned UE supporting NES capability is a UE supporting the capability of camping on an on-demand SIB1 cell. This capability may be an optional capability of the UE or a mandatory capability of R19 UE.

[0196] Example 2: SIB1 message update process of on-demand NES cell (i.e., on-demand SIB1 cell);

[0197] For on-demand SIB1 NES cells, the network begins transmitting SIB1 messages after obtaining the UE's WUS information. If there are no UEs in the RRC connected state, to save power, the network does not need to transmit SIB1 messages constantly or frequently; it can be turned off or transmitted sparsely. In this case, UEs that support this function can still reside in the cell and listen for paging messages.

[0198] In this scenario, if the SIB1 message of the on-demand SB1 cell is updated, the UE and the cell need to agree on a SIB1 message update period. For example, through the system information update indication (i.e., the third indication information) in the paging message, if the SIB1 is updated, the base station sends the updated SIB1 message at the configured period. The UE reads the new SIB1 message at the configured period, or the UE obtains the SIB1 message through dedicated signaling.

[0199] Through the above solution, the network energy-saving terminal can reside in the on-demand SIB1 cell, and then can monitor paging messages and access the on-demand SIB1 cell without having to perform cell measurement on the on-demand SIB1 cell, thereby effectively reducing the delay during service access.

[0200] As shown in FIG4 , an embodiment of the present disclosure further provides a cell camping method, which is performed by a network-side device. The method includes:

[0201] Step 401: Send first indication information, where the first indication information is used to indicate that a network energy-saving terminal is allowed to access a cell that sends SIB1 on demand or that a network energy-saving terminal is prohibited from accessing a cell that sends SIB1 on demand.

[0202] In the embodiment of the present disclosure, by sending the first indication information, the network energy-saving terminal can reside in the on-demand SIB1 cell, and then can subsequently monitor the paging message and access the on-demand SIB1 cell without having to perform cell measurement on the on-demand SIB1 cell, thereby effectively reducing the delay during service access.

[0203] In some embodiments, sending the first indication information includes:

[0204] The first indication information is sent by sending at least one of the MIB and SIB1 of the SIB1 cell on demand.

[0205] For example, the first indication information may be UAC in the MIB or SIB, or may be indication information newly added in the MIB or SIB1 for indicating whether to allow or prohibit the network energy-saving terminal from accessing the on-demand SIB1 cell.

[0206] In some embodiments, the method of the present disclosure further includes:

[0207] Sending the SIB1 in the on-demand SIB1 sending cell;

[0208] Alternatively, the on-demand SIB1 sending cell SIB1 is sent via a system message or dedicated signaling of a neighboring cell of the on-demand SIB1 sending cell.

[0209] In some embodiments, the method of the present disclosure further includes:

[0210] A master information block of the on-demand SIB1 cell is sent, where the master information block includes second indication information, and the second indication information is used to indicate that the cell is an on-demand SIB1 cell.

[0211] Here, the second indication information enables the terminal to determine that the cell is an on-demand SIB1 cell.

[0212] In some embodiments, the method of the present disclosure further includes:

[0213] Send third indication information, where the third indication information is used to indicate that SIB1 of the cell is updated.

[0214] As an implementation manner, the third indication information is sent through a paging message.

[0215] In some embodiments, the method of the present disclosure further includes:

[0216] The updated SIB1 is sent according to a pre-agreed or network-configured period.

[0217] In the embodiment of the present disclosure, when the SIB1 of the on-demand SIB1 cell is updated, the on-demand SIB1 cell notifies the UE that its SIB1 message has been updated, and the UE receives the updated SIB1 through a pre-agreed or network-configured period, so that it can reside in the cell according to the updated SIB1.

[0218] In some embodiments, the method of the present disclosure further includes:

[0219] When the function of sending SIB1 on demand of the cell corresponding to the network side device is changed, fourth indication information is sent to the neighboring base station, where the fourth indication information is used to indicate that the function of sending SIB1 on demand of the cell is changed.

[0220] In some embodiments, the method of the present disclosure further includes:

[0221] Acquire fifth indication information sent by a neighboring cell, where the fifth indication information is used to indicate that a function of sending SIB1 on demand of the neighboring cell has changed;

[0222] According to the fifth indication information, the wake-up signal configuration information related to the neighbor cell in the system message is updated, or indication information that the on-demand SIB1 sending function of the neighbor cell has changed is included in the system information.

[0223] In some embodiments, the change in the function of sending SIB1 on demand includes at least one of the following:

[0224] Send SIB1 function activation on demand;

[0225] Send SIB1 function on demand deactivation;

[0226] Enable the function of sending SIB1 on demand;

[0227] Disable the function of sending SIB1 on demand.

[0228] The above wake-up signal configuration information is used to trigger the cell to send SIB1.

[0229] In the case where the above-mentioned function of sending SIB1 on demand is changed to deactivation or disabling of the function of sending SIB1 on demand: according to the fifth indication information, the wake-up signal configuration information related to the neighboring cell in the system message is updated, including: deleting the identification information of the cell whose function is deactivated or disabled in the wake-up signal configuration information, or deleting the WUS configuration information of the cell whose function is deactivated or disabled in the wake-up signal configuration information; including indication information of the change of the function of sending SIB1 on demand of the neighboring cell in the system information, including: indication information of deactivation or disabling of the function of sending SIB1 on demand of the sending cell.

[0230] In the case where the above-mentioned function of sending SIB1 on demand is changed to the function of activating or enabling sending SIB1 on demand: according to the fifth indication information, the wake-up signal configuration information related to the neighboring cell in the system message is updated, including: adding the identification information of the cell whose function is activated or enabled in the wake-up signal configuration information; including the indication information of the change of the function of sending SIB1 on demand of the neighboring cell in the system information, including: the indication information of activating or enabling the function of sending SIB1 on demand of the sending cell.

[0231] The cell camping method disclosed in the present invention is described below with reference to embodiments.

[0232] Example 3: Cancellation process of NES on-demand SIB1 function;

[0233] As shown in Figure 5, it includes:

[0234] Step 1: gNB2 decides to disable the on-demand SIB1 function.

[0235] Specifically, if the cell access related bit in the MIB message or SIB1 message of the gNB2 cell is set to not allow access, the relevant NES UEs are prohibited from accessing.

[0236] Step 2: Notify neighboring base station gNB1 via the Xn interface that its on-demand SIB1 function has been canceled.

[0237] Step 3: gNB1 updates the system message, cancels the WUS configuration related to the cell in the system message or the cell identification information in the WUS configuration, or sends an indication in the system message that the on-demand SIB function of the cell is not used.

[0238] In the embodiment of the present disclosure, by sending the first indication information, the network energy-saving terminal can reside in the on-demand SIB1 cell, and then can subsequently monitor the paging message and access the on-demand SIB1 cell without having to perform cell measurement on the on-demand SIB1 cell, thereby effectively reducing the delay during service access.
