[0223] In the embodiments of the present disclosure, the term “and / or” describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character “ / ” generally represents an “or” relationship between the associated objects before and after it.

[0224] In the embodiments of the present disclosure, the term “multiple” means two or more, and other quantifiers are similar.

[0225] In the embodiments of this disclosure, the terms "first," "second," etc., are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this disclosure can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, and the number of objects is not limited; for example, the first object can be one or more.

[0226] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0227] To facilitate a clearer understanding of the technical solutions of the embodiments of this disclosure, the network energy-saving modes involved in the embodiments of this disclosure will be introduced first.

[0228] 1. On-demand Synchronization Signal Block (SSB) mode

[0229] On-demand SSB transmission technology allows base stations to send SSBs on demand, rather than at fixed time intervals or predetermined times. If a cell activates on-demand SSB mode, it cannot serve all terminals as a PCell because on-demand SSB transmission technology only applies to secondary cells (SCells). Therefore, if a cell is a PCell, entering on-demand SSB mode prevents it from functioning as a PCell, effectively deactivating it for neighboring cells. This can lead to terminal access failures and low network coverage efficiency.

[0230] 2. SSB Adaptive Mode

[0231] Common Signaling / Channel Adaptive Technology (SSB) allows for adaptive adjustment of parameters such as the SSB period. If a cell activates SSB adaptive mode, it cannot serve all terminals as a PCell because SSB adaptive technology only applies to SCells. Therefore, if a cell is a PCell, entering SSB adaptive mode prevents it from functioning as a PCell, effectively putting neighboring cells in a deactivated state, which may lead to terminal access failures and low network coverage efficiency.

[0232] 3. On demand system information block 1 (SIB1) mode

[0233] The on demand SIB1 transmission technology allows the base station to transmit the SIB1 as needed, instead of broadcasting the SIB1 according to a fixed period. If a cell is switched from the normal cell mode to the on demand SIB1 mode, the cell cannot serve legacy terminals as a PCell. The legacy terminals refer to terminals that are not of the 3rd Generation Partnership Project Release 19 (3GPP R19). Therefore, if a cell is a PCell, after the cell enters the on demand SIB1 mode, the cell cannot serve legacy terminals as a PCell, which can cause problems such as access failure of the legacy terminals and low network coverage efficiency.

[0234] FIG. 1 is a flowchart of an information indication method provided by an embodiment of the present disclosure, which is applied to a first network device. As shown in FIG. 1, the method includes step 101.

[0235] In step 101, first network energy saving mode indication information is sent to a second network device. The first network energy saving mode indication information is used to indicate cell information of a cell in which a network energy saving mode is activated and / or cell information of a cell in which the network energy saving mode is deactivated.

[0236] Specifically, the second network device can be a neighbor network device of the first network device, which can be referred to as a neighbor Next Generation-Radio Access Network (NG-RAN) node in some examples.

[0237] In some embodiments, the first network device sends the first network energy saving mode indication information to the second network device. The first network energy saving mode indication information can be used to indicate cell information of a cell in which a network energy saving mode is activated, and can also be used to indicate cell information of a cell in which the network energy saving mode is deactivated. In actual use, whether the first network energy saving mode indication information specifically indicates the cell information of the cell in which the network energy saving mode is activated or the cell information of the cell in which the network energy saving mode is deactivated can have various possible implementation manners, which are not limited by the present disclosure.

[0238] For example, an activation or deactivation indication can be included in the first network energy saving mode indication information. The activation or deactivation indication is used to indicate whether the cell information indicated by the current first network energy saving mode indication information is the cell information of the cell in which the network energy saving mode is activated or the cell information of the cell in which the network energy saving mode is deactivated.

[0239] For another example, the current cell information indicated by the first network energy saving mode indication information can be indicated by the coverage state of the cell indicated by the first network energy saving mode indication information, whether the cell information is the cell information of the network energy saving mode activated or the cell information of the network energy saving mode deactivated. For example, if the value of the coverage state of the cell is 0, it indicates that the current first network energy saving mode indication information indicates the cell information of the network energy saving mode activated; if the value of the coverage state of the cell is a non-0 value, it indicates that the current first network energy saving mode indication information indicates the cell information of the network energy saving mode deactivated.

[0240] In some embodiments, the first network energy saving mode indication information can be used to indicate the cell information of the network energy saving mode activated and the cell information of the network energy saving mode deactivated in the cell served by the first network device. For example, one piece of first network energy saving mode indication information indicates both the cell information of the network energy saving mode activated and the cell information of the network energy saving mode deactivated, and for a specific indicated cell, whether the cell is the cell of the network energy saving mode activated or the cell of the network energy saving mode deactivated can be determined by the coverage state of the cell indicated by the first network energy saving mode indication information.

[0241] It should be noted that the “activation” in the disclosure can be replaced by terms with similar meanings such as “application”, “entry”, etc. The “deactivation” in the disclosure can be replaced by terms with similar meanings such as “non-application”, “exit”, etc.

[0242] In some embodiments, the first network device can send an NG-RAN node configuration update message to the second network device, and the NG-RAN node configuration update message carries the first network energy saving mode indication information. The information element (IE) of the first network energy saving mode indication information can be a newly designed IE, or the coverage range modification notification IE in the existing NG-RAN node configuration update message can be reused to reduce the signaling design.

[0243] In some embodiments, the first network device can also carry the first network energy saving mode indication information through other messages other than the NG-RAN node configuration update message, and the disclosure is not limited.

[0244] In the present disclosure, the first network device can send first network energy saving mode indication information to the second network device, indicating cell information of a cell served by the first network device activating a network energy saving mode, and / or indicating cell information of a cell deactivating the network energy saving mode. This enables the second network device to learn the activation or deactivation of the network energy saving mode of the cell served by the first network device, so that the second network device can perform relevant operations in reference to the activation and / or deactivation of the network energy saving mode of the cell served by the first network device, to ensure terminal access and improve network coverage efficiency.

[0245] In some embodiments, the network energy saving mode comprises one or more of: an on-demand SSB mode; an SSB adaptive mode; an on-demand SIB1 mode.

[0246] In some embodiments, the first network energy saving mode indication information comprises one or more of:

[0247] First on-demand SSB mode indication information, the first on-demand SSB mode indication information being used to indicate cell information of a cell served by the first network device activating an on-demand SSB mode and / or deactivating the on-demand SSB mode;

[0248] First SSB adaptive mode indication information, the first SSB adaptive mode indication information being used to indicate cell information of a cell served by the first network device activating an SSB adaptive mode and / or deactivating the SSB adaptive mode;

[0249] First on-demand SIB1 mode indication information, the first on-demand SIB1 mode indication information being used to indicate cell information of a cell served by the first network device activating an on-demand SIB1 mode and / or deactivating the on-demand SIB1 mode.

[0250] In some embodiments, the first on-demand SSB mode indication information contains one or more of the following information:

[0251] Cell identification;

[0252] Coverage status of the cell;

[0253] SSB list of the cell;

[0254] Coverage status of each SSB in the SSB list;

[0255] The coverage modification reason is network energy saving.

[0256] The coverage state of the cell refers to the cell being in an active (or activated) state or an inactive (or deactivated) state, and can also be expressed as the coverage configuration of the cell. In some embodiments, the coverage state of the cell can be expressed by a coverage value, for example, a coverage value of 0 of the cell indicates that the cell is in an inactive state, and a coverage value other than 0 of the cell indicates that the cell is in an active state.

[0257] The coverage state of the SSB refers to the SSB being in an activated state or a deactivated state, and can also be expressed as the coverage configuration of the SSB. In some embodiments, the coverage state of the SSB can be expressed by a coverage value, for example, a coverage value of 0 of the SSB indicates that the SSB is in a deactivated state, and a coverage value other than 0 of the SSB indicates that the SSB is in an activated state.

[0258] The SSB list can include one or more SSB indexes.

[0259] The first on-demand SSB mode indication information can be cell-level on-demand SSB mode indication information or SSB-level on-demand SSB mode indication information.

[0260] For example, the first on-demand SSB mode indication information carries one or more pieces of cell-level information such as a cell identifier, a coverage state of the cell, a coverage modification reason, and the like, and the first on-demand SSB mode indication information is cell-level on-demand SSB mode indication information.

[0261] For another example, the first on-demand SSB mode indication information carries one or more pieces of SSB-level information such as a SSB list of the cell, a coverage state of each SSB in the SSB list, and the like, in addition to cell-level information, and the first on-demand SSB mode indication information is SSB-level on-demand SSB mode indication information.

[0262] In some embodiments, the first SSB adaptation mode indication information includes one or more pieces of information as follows:

[0263] A cell identifier;

[0264] A coverage state of the cell;

[0265] A SSB list of the cell;

[0266] A coverage state of each SSB in the SSB list;

[0267] The coverage modification reason is network energy saving.

[0268] The first SSB adaptive mode indication information contains the same information as the first on-demand SSB mode indication information, and the description is not repeated here.

[0269] The first SSB adaptive mode indication information can be cell-level SSB adaptive mode indication information or SSB-level SSB adaptive mode indication information.

[0270] For example, the first SSB adaptive mode indication information carries one or more pieces of cell-level information such as cell identifier, coverage state of the cell, coverage modification reason, etc., and the first SSB adaptive mode indication information is cell-level SSB adaptive mode indication information.

[0271] For another example, the first SSB adaptive mode indication information carries one or more pieces of SSB-level information such as SSB list of the cell, coverage state of each SSB in the SSB list, etc., in addition to the cell-level information, and the first SSB adaptive mode indication information is SSB-level SSB adaptive mode indication information.

[0272] In some embodiments, the first on-demand SIB1 mode indication information contains one or more pieces of information as follows:

[0273] Cell identifier;

[0274] On-demand SIB1 mode indication of the cell;

[0275] SSB list of the cell;

[0276] On-demand SIB1 mode indication of each SSB in the SSB list.

[0277] The on-demand SIB1 mode indication of the cell is used to indicate that the on-demand SIB1 mode of the cell is in an activated state or a deactivated state.

[0278] The on-demand SIB1 mode indication of the SSB is used to indicate that the on-demand SIB1 mode of the SSB is in an activated state or a deactivated state. When the on-demand SIB1 mode of the SSB is in the activated state, the SSB cannot serve traditional terminals as the SSB of the PCell.

[0279] The first on-demand SIB1 mode indication information can be cell-level on-demand SIB1 mode indication information or SSB-level on-demand SIB1 mode indication information.

[0280] For example, the first on-demand SIB1 mode indication information carries cell-level information, such as one or more of the following: cell identifier, on-demand SIB1 mode indication of the cell, and the like. The first on-demand SIB1 mode indication information is cell-level on-demand SIB1 mode indication information.

[0281] For another example, the first on-demand SIB1 mode indication information carries not only cell-level information but also SSB-level information, such as one or more of the following: SSB list of the cell, on-demand SIB1 mode indication of each SSB in the SSB list, and the like. The first on-demand SIB1 mode indication information is SSB-level on-demand SIB1 mode indication information.

[0282] In some embodiments, the method further includes:

[0283] According to the OAM configuration, determining a neighbor cell corresponding to the energy-saving cell served by the first network device and a network device serving the neighbor cell, for sending the WUS configuration.

[0284] The energy-saving cell refers to a cell that can support entering a network energy-saving mode.

[0285] For example, for the on-demand SIB1 scenario, the neighbor cell can need to send the terminal the uplink wake-up signal (WUS) configuration (referred to as WUS configuration in the present disclosure) for the cell entering the on-demand SIB1 mode. The first network device can send the WUS configuration to the neighbor cell corresponding to the energy-saving cell served by the first network device for sending the WUS configuration (i.e., the neighbor cell can send the WUS configuration to the terminal for the energy-saving cell) before the on-demand SIB1 mode of the energy-saving cell is activated, or in the case that the WUS configuration of the energy-saving cell changes. The first network device can determine the neighbor cell corresponding to the energy-saving cell for sending the WUS configuration and the network device serving the neighbor cell according to the operation management and maintenance (OAM) configuration, so as to provide the WUS configuration of the energy-saving cell to the neighbor cell.

[0286] In some embodiments, the neighbor cell can include a cell served by a neighbor network device.

[0287] In some embodiments, sending the first network energy-saving mode indication information to the second network device includes:

[0288] The DU of the first network device sends second network energy saving mode indication information to the CU of the first network device, and the second network energy saving mode indication information is used to indicate cell information in which the network energy saving mode is activated and / or deactivated in a cell served by the DU of the first network device.

[0289] The CU of the first network device sends first network energy saving mode indication information to the second network device based on the second network energy saving mode indication information.

[0290] Specifically, in some network structures, a network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can be arranged geographically apart, that is, the CU and the DU are separated, so that the network deployment is more flexible. In actual deployment, one CU can manage one or more DUs.

[0291] For the scenario of CU and DU separation, after the DU triggers the network energy saving mode indication information, such as the DU of the first network device activating / deactivating the network energy saving mode of a cell and / or an SSB, the DU of the first network device sends second network energy saving mode indication information to the CU of the first network device, indicating cell information in which the network energy saving mode is activated in a cell served by the DU, or indicating cell information in which the network energy saving mode is deactivated in a cell served by the DU. After the CU of the first network device receives the second network energy saving mode indication information, the CU of the first network device can send the above-mentioned first network energy saving mode indication information to the second network device based on the second network energy saving mode indication information. For example, the CU of the first network device can send the second network energy saving mode indication information to the second network device as the first network energy saving mode indication information, or the CU of the first network device can generate the first network energy saving mode indication information based on the second network energy saving mode indication information sent by one or more DUs, and then send the first network energy saving mode indication information to the second network device.

[0292] In some embodiments, the DU of the first network device can send a gNB-DU configuration update message to the CU of the first network device, and the gNB-DU configuration update message carries the second network energy saving mode indication information. The IE of the second network energy saving mode indication information can be a newly designed IE, or the coverage range modification notification IE in the existing gNB-DU configuration update message can be reused to reduce signaling design.

[0293] In some embodiments, the DU of the first network device can also carry the second network energy saving mode indication information through other messages other than the gNB-DU configuration update message, and the present disclosure is not limited.

[0294] In some embodiments, the second network energy saving mode indication information comprises one or more of:

[0295] second on-demand SSB mode indication information, the second on-demand SSB mode indication information being used to indicate cell information in which an on-demand SSB mode is activated and / or in which the on-demand SSB mode is deactivated in a cell served by the DU of the first network device;

[0296] second SSB adaptive mode indication information, the second SSB adaptive mode indication information being used to indicate cell information in which a SSB adaptive mode is activated and / or in which the SSB adaptive mode is deactivated in a cell served by the DU of the first network device;

[0297] second on-demand SIB1 mode indication information, the second on-demand SIB1 mode indication information being used to indicate cell information in which an on-demand SIB1 mode is activated and / or in which the on-demand SIB1 mode is deactivated in a cell served by the DU of the first network device.

[0298] In some embodiments, the second on-demand SSB mode indication information comprises one or more of:

[0299] a cell identity;

[0300] a coverage status of the cell;

[0301] an SSB list of the cell;

[0302] a coverage status of each SSB in the SSB list;

[0303] a coverage modification cause being on-demand SSB mode activation.

[0304] In some embodiments, the second SSB adaptive mode indication information comprises one or more of:

[0305] a cell identity;

[0306] a coverage status of the cell;

[0307] an SSB list of the cell;

[0308] a coverage status of each SSB in the SSB list;

[0309] a coverage modification cause being SSB adaptive mode activation.

[0310] In some embodiments, the second on-demand SIB1 mode indication information comprises one or more of:

[0311] cell identity;

[0312] on-demand SIB1 mode indication of the cell;

[0313] SSB list of the cell;

[0314] on-demand SIB1 mode indication of each SSB in the SSB list.

[0315] In some embodiments, the method further comprises: determining, by the CU of the first network device, network energy saving mode activation of the cell and / or SSB served by the DU of the first network device or determining network energy saving mode deactivation of the cell and / or SSB served by the DU of the first network device based on the second network energy saving mode indication information.

[0316] For example, the CU of the first network device can determine which cells and / or SSBs of the cells and / or SSBs served by the DU of the first network device enter the network energy saving mode and which type of network energy saving mode it is based on the information content contained in the second network energy saving mode indication information, so as to determine that these cells cannot serve terminals as PCells or that these SSBs cannot serve terminals as SSBs of PCells.

[0317] For another example, the CU of the first network device can determine which cells and / or SSBs of the cells and / or SSBs served by the DU of the first network device leave the network energy saving mode and which type of network energy saving mode it is based on the information content contained in the second network energy saving mode indication information, so as to determine that these cells can serve terminals as PCells again or that these SSBs can serve terminals as SSBs of PCells again.

[0318] In some embodiments, if the coverage status of the cell or SSB served by the DU of the first network device contained in the second on-demand SSB mode indication information is 0 and the coverage modification cause contained is on-demand SSB mode activation, the CU of the first network device can determine on-demand SSB mode activation of the cell or SSB served by the DU of the first network device; or if the coverage status of the cell or SSB served by the DU of the first network device contained in the second on-demand SSB mode indication information is not 0, the CU of the first network device can determine on-demand SSB mode deactivation of the cell or SSB served by the DU of the first network device.

[0319] In some embodiments, if the second SSB adaptation mode indication information contains a coverage state of a cell or SSB served by the DU of the first network device as 0 and a coverage modification cause as SSB adaptation mode activation, the CU of the first network device can determine that the SSB adaptation mode of the cell or SSB served by the DU of the first network device is activated; or if the second SSB adaptation mode indication information contains a coverage state of a cell or SSB served by the DU of the first network device as not 0, the CU of the first network device can determine that the SSB adaptation mode of the cell or SSB served by the DU of the first network device is deactivated.

[0320] In some embodiments, the method further comprises: the CU of the first network device sending a cell list allowed to activate the network energy saving mode and / or a SSB list allowed to activate the network energy saving mode to the DU of the first network device.

[0321] Specifically, the CU of the first network device can determine which cells and / or SSBs are allowed to activate the network energy saving mode, and then send the cell list allowed to activate the network energy saving mode and / or the SSB list allowed to activate the network energy saving mode to the DU of the first network device, and the DU of the first network device can determine which cells and / or SSBs to activate the network energy saving mode when network energy saving is needed, by referring to the cell list allowed to activate the network energy saving mode and / or the SSB list allowed to activate the network energy saving mode.

[0322] In some embodiments, the method further comprises: the DU of the first network device determining, based on the cell list allowed to activate the network energy saving mode and / or the SSB list allowed to activate the network energy saving mode, that the cells in the cell list and / or the SSBs in the SSB list are allowed to activate the network energy saving mode for the purpose of network energy saving.

[0323] For example, the CU of the first network device carries the cell list allowed to activate the network energy saving mode and / or the SSB list allowed to activate the network energy saving mode in a gNB-CU configuration update message, and after receiving the gNB-CU configuration update message, the DU of the first network device can determine that the cells in the cell list and / or the SSBs in the SSB list are allowed to activate the network energy saving mode for the purpose of network energy saving.

[0324] In some embodiments, the method further comprises: receiving first network energy saving mode deactivation request information sent by the second network device, the first network energy saving mode deactivation request information containing a cell list and / or a SSB list served by the first network device requested by the second network device to deactivate the network energy saving mode.

[0325] For example, in the case that the cell load of the second network device is too large, such as the load exceeds a preset threshold or is limited by other performance indicators and cannot bear too large load, the second network device can send a first network energy saving mode deactivation request information to the first network device, requesting the first network device to deactivate the network energy saving mode of some cells and / or SSBs, so that these cells return to the normal cell mode to offload part of the cell load of the second network device.

[0326] In some embodiments, the second network device can send an NG-RAN node configuration update message to the first network device, and the NG-RAN node configuration update message carries the first network energy saving mode deactivation request information.

[0327] For the on-demand SSB mode or the SSB adaptive mode, deactivating the on-demand SSB mode or the SSB adaptive mode of a cell is equivalent to making the cell enter the active state, and deactivating the on-demand SSB mode or the SSB adaptive mode of an SSB is equivalent to making the SSB enter the active state, so in some embodiments, for the on-demand SSB mode or the SSB adaptive mode, the second network device can send a cell activation request message to the first network device, and the cell activation request message carries the first network energy saving mode deactivation request information. The IE of the first network energy saving mode deactivation request information can be a newly designed IE, or can reuse the existing IE in the cell activation request message.

[0328] In some embodiments, the second network device can also carry the first network energy saving mode deactivation request information through other messages other than the NG-RAN node configuration update message or the cell activation request message, and the present disclosure is not limited.

[0329] In some embodiments, the method further includes: based on the first network energy saving mode deactivation request information, deactivating the network energy saving mode of the cells in the cell list and / or deactivating the network energy saving mode of the SSBs in the SSB list.

[0330] It should be noted that the cells and / or SSBs of the first network device that are actually deactivated from the network energy saving mode can not be completely determined according to the cell list and / or SSB list contained in the first network energy saving mode deactivation request information, but the first network device can use the first network energy saving mode deactivation request information as a reference to determine which cells and / or SSBs to deactivate from the network energy saving mode.

[0331] In some embodiments, the first network energy saving mode deactivation request information includes one or more of the following:

[0332] first on-demand SSB mode deactivation request information, the first on-demand SSB mode deactivation request information containing a cell list and / or an SSB list of cells served by the first network device that the second network device requests to deactivate the on-demand SSB mode;

[0333] first SSB adaptive mode deactivation request information, the first SSB adaptive mode deactivation request information containing a cell list and / or an SSB list of cells served by the first network device that the second network device requests to deactivate the SSB adaptive mode;

[0334] first on-demand SIB1 mode deactivation request information, the first on-demand SIB1 mode deactivation request information containing a cell list and / or an SSB list of cells served by the first network device that the second network device requests to deactivate the on-demand SIB1 mode.

[0335] In some embodiments, based on the first network energy saving mode deactivation request information, deactivating the network energy saving mode of the cells in the cell list and / or deactivating the network energy saving mode of the SSBs in the SSB list comprises:

[0336] The CU of the first network device sends, based on the first network energy saving mode deactivation request information, second network energy saving mode deactivation request information to the DU of the first network device, the second network energy saving mode deactivation request information containing a cell list and / or an SSB list of cells served by the first network device that the second network device requests to deactivate the network energy saving mode.

[0337] Specifically, for the scenario of CU and DU separation, the CU of the first network device can send the second network energy saving mode deactivation request information to the DU of the first network device after receiving the first network energy saving mode deactivation request information, where the CU of the first network device can send the first network energy saving mode deactivation request information as the second network energy saving mode deactivation request information to the DU of the first network device, or the CU of the first network device can generate the second network energy saving mode deactivation request information based on the first network energy saving mode deactivation request information and then send the second network energy saving mode deactivation request information to the DU of the first network device.

[0338] In some embodiments, the CU of the first network device can send a gNB-CU configuration update message (GNB-CU configuration update message) to the DU of the first network device, the gNB-CU configuration update message carrying the second network energy saving mode deactivation request information.

[0339] In some embodiments, the first network device can also carry the second network energy saving mode deactivation request information through other messages than the gNB-CU configuration update message, and the present disclosure is not limited thereto.

[0340] In some embodiments, based on the first network energy saving mode deactivation request information, deactivating the network energy saving mode of the cells in the cell list and / or deactivating the network energy saving mode of the SSBs in the SSB list further comprises:

[0341] The DU of the first network device deactivates the network energy saving mode of the cells in the cell list and / or deactivates the network energy saving mode of the SSBs in the SSB list based on the second network energy saving mode deactivation request information.

[0342] It should be noted that the cells and / or SSBs whose network energy saving mode is actually deactivated by the DU of the first network device can be completely determined according to the cell list and / or SSB list contained in the second network energy saving mode deactivation request information, or can not be completely determined according to the cell list and / or SSB list contained in the second network energy saving mode deactivation request information. The DU of the first network device can take the second network energy saving mode deactivation request information as a reference to determine which cells and / or SSBs to deactivate the network energy saving mode.

[0343] In some embodiments, the second network energy saving mode deactivation request information comprises one or more of the following:

[0344] Second on-demand SSB mode deactivation request information, the second on-demand SSB mode deactivation request information containing a cell list and / or SSB list of the first network device served by the second network device requesting to deactivate the on-demand SSB mode;

[0345] Second SSB adaptive mode deactivation request information, the second SSB adaptive mode deactivation request information containing a cell list and / or SSB list of the first network device served by the second network device requesting to deactivate the SSB adaptive mode;

[0346] Second on-demand SIB1 mode deactivation request information, the second on-demand SIB1 mode deactivation request information containing a cell list and / or SSB list of the first network device served by the second network device requesting to deactivate the on-demand SIB1 mode.

[0347] In some embodiments, the second network device requests a list of cells served by the first network device in which the on-demand SSB mode is deactivated, including a list of cells served by the first network device in which the second network device requests the on-demand SSB mode to be activated; and / or, the second network device requests a list of SSBs served by the first network device in which the on-demand SSB mode is deactivated, including a list of SSBs served by the first network device in which the second network device requests the on-demand SSB mode to be activated.

[0348] For example, for the on-demand SSB mode, deactivating the on-demand SSB mode of a cell is equivalent to making the cell enter an activated state, and deactivating the on-demand SSB mode of an SSB is equivalent to making the SSB enter an activated state, so the on-demand SSB mode of the cell and / or the SSB can be deactivated by sending a cell activation request message, and the existing signaling design is reused to save overhead.

[0349] In some embodiments, the second network device requests a list of cells served by the first network device in which the SSB adaptive mode is deactivated, including a list of cells served by the first network device in which the second network device requests the SSB adaptive mode to be activated; and / or, the second network device requests a list of SSBs served by the first network device in which the SSB adaptive mode is deactivated, including a list of SSBs served by the first network device in which the second network device requests the SSB adaptive mode to be activated.

[0350] For example, for the SSB adaptive mode, deactivating the SSB adaptive mode of a cell is equivalent to making the cell enter an activated state, and deactivating the SSB adaptive mode of an SSB is equivalent to making the SSB enter an activated state, so the SSB adaptive mode of the cell and / or the SSB can be deactivated by sending a cell activation request message, and the existing signaling design is reused to save overhead.

[0351] FIG. 2 is a flow diagram of a method for indicating information according to an embodiment of the present disclosure, which is applied to a second network device, as shown in FIG. 2, the method includes steps 201 and 202.

[0352] In step 201, first network energy saving mode indication information sent by a first network device is received.

[0353] In step 202, based on the first network energy saving mode indication information, cell information of cells served by the first network device in which the network energy saving mode is activated and / or the network energy saving mode is deactivated is determined.

[0354] Specifically, the second network device can be a neighbor network device of the first network device, which can be referred to as a neighbor NG-RAN node in some examples.

[0355] In the disclosure, the first network device can send first network energy saving mode indication information to the second network device, indicating cell information of a cell served by the first network device in which the network energy saving mode is activated, or indicating cell information of a cell in which the network energy saving mode is deactivated. This enables the second network device to learn the activation or deactivation of the network energy saving mode of the cell served by the first network device, so that the second network device can perform related operations in reference to the activation or deactivation of the network energy saving mode of the cell served by the first network device, to ensure terminal access and improve network coverage efficiency.

[0356] In some embodiments, the method further comprises: based on the first network energy saving mode indication information, performing one or more of the following operations:

[0357] (1) Adjusting the coverage of the cell and / or SSB served by the second network device.

[0358] For example, the first network energy saving mode indication information is a network energy saving mode activation indication, i.e., indicating cell information of a cell served by the first network device in which the network energy saving mode is activated, the second network device may need to accordingly expand the coverage of certain cells and / or SSBs served by the second network device, to ensure terminal access and improve network coverage efficiency.

[0359] For another example, the first network energy saving mode indication information is a network energy saving mode deactivation indication, i.e., indicating cell information of a cell served by the first network device in which the network energy saving mode is deactivated, the second network device can accordingly reduce the coverage of certain cells and / or SSBs served by the second network device according to the information contained in the network energy saving mode deactivation indication, to reduce network device energy consumption and alleviate load pressure.

[0360] (2) Broadcasting the WUS configuration of the first cell, or stopping broadcasting the WUS configuration of the second cell, the first cell being a cell served by the first network device in which the on-demand SIB1 mode is activated, and the second cell being a cell served by the first network device in which the on-demand SIB1 mode is deactivated.

[0361] For example, for the on-demand SIB1 scenario, the cell served by the second network device may need to send WUS configuration to terminals for the first network device served by the cell entering the on-demand SIB1 mode, the second network device can determine which cell to broadcast the WUS configuration or stop broadcasting the WUS configuration of which cell in reference to the first network energy saving mode indication information, and can also determine when to send the WUS configuration or when to stop sending the WUS configuration in reference to the first network energy saving mode indication information.

[0362] In some embodiments, the first network energy saving mode indication information comprises one or more of the following:

[0363] first on-demand SSB mode indication information, the first on-demand SSB mode indication information being used to indicate cell information in which an on-demand SSB mode is activated and / or in which the on-demand SSB mode is deactivated in a cell served by the first network device;

[0364] first SSB adaptive mode indication information, the first SSB adaptive mode indication information being used to indicate cell information in which an SSB adaptive mode is activated and / or in which the SSB adaptive mode is deactivated in a cell served by the first network device;

[0365] first on-demand SIB1 mode indication information, the first on-demand SIB1 mode indication information being used to indicate cell information in which an on-demand SIB1 mode is activated and / or in which the on-demand SIB1 mode is deactivated in a cell served by the first network device.

[0366] In some embodiments, the first on-demand SSB mode indication information comprises one or more of the following information:

[0367] a cell identity;

[0368] a coverage status of the cell;

[0369] an SSB list of the cell;

[0370] a coverage status of each SSB in the SSB list;

[0371] the coverage modification reason is network energy saving.

[0372] In some embodiments, the first SSB adaptive mode indication information comprises one or more of the following information:

[0373] a cell identity;

[0374] a coverage status of the cell;

[0375] an SSB list of the cell;

[0376] a coverage status of each SSB in the SSB list;

[0377] the coverage modification reason is network energy saving.

[0378] In some embodiments, the method further comprises: in a case where the coverage modification reason is network energy saving, determining that the coverage modification reason of the cell and / or the SSB is to activate the on-demand SSB mode or to activate the SSB adaptive mode.

[0379] In some embodiments, the first on-demand SIB1 mode indication information contains one or more of the following information:

[0380] a cell identity;

[0381] an on-demand SIB1 mode indication of the cell;

[0382] an SSB list of the cell;

[0384] In some embodiments, the method further comprises: sending, to the first network device, first network energy saving mode deactivation request information, the first network energy saving mode deactivation request information containing a list of cells and / or an SSB list of cells served by the first network device and requested by the second network device to be deactivated from the network energy saving mode.

[0385] The methods provided by the various embodiments of the present disclosure are based on the same technical concept, and therefore the implementation of each method can be referred to each other, and the repeated parts will not be described again.

[0386] The methods provided by the various embodiments of the present disclosure are based on the same technical concept, and therefore the implementation of each method can be referred to each other, and the repeated parts will not be described again.

[0387] Example 1: On-demand SSB mode indication, gNB-CU and gNB-DU separation.

[0388] FIG. 3 is a flowchart of Example 1 provided by the embodiments of the present disclosure, as shown in FIG. 3, the first network device includes a gNB-CU and a gNB-DU, the first network device supports the cell entering the on-demand SSB mode, and the interaction process of Example 1 includes:

[0389] Step 1-1: The gNB-CU sends a list of cells or an SSB list allowed to activate the on-demand SSB mode to the gNB-DU, and the gNB-CU can carry the IE through a gNB-CU configuration update message.

[0390] Step 1-2: The gNB-DU replies with a gNB-CU configuration update response message.

[0391] If the IE of the list of cells or the SSB list allowed to activate the on-demand SSB mode is contained in the gNB-CU configuration update message, the gNB-DU shall consider that the cell or the SSB beam within the cell is allowed to enter the on-demand SSB mode for the purpose of network energy saving.

[0392] After receiving the cell list of on demand SSB mode allowed to activate sent by gNB-CU, gNB-DU can activate the on demand SSB mode of the cell. After the cell enters the on demand SSB mode, SSB becomes more sparse, the coverage of SSB changes, the cell changes from PCell to SCell, and cannot support the access of traditional terminals, and the terminals of neighboring cells cannot be handed over to the cell.

[0393] When the on demand SSB mode of the cell changes: on demand SSB mode activation or on demand SSB mode deactivation, gNB-DU sends on-demand SSB mode indication information to gNB-CU.

[0394] Step 2-1: gNB-DU sends on-demand SSB mode indication information to gNB-CU. Wherein, the on-demand SSB mode indication information is used to indicate the activation or deactivation of the on-demand SSB mode, the IE can be SSB level or cell level, and the IE at least contains one of the following information: cell identification, coverage state of the cell, SSB list of the cell, coverage state of each SSB in the SSB list, and coverage modification reason (on demand SSB mode activation).

[0395] gNB-DU can send gNB-DU configuration update message to gNB-CU, and the gNB-DU configuration update message carries coverage range modification notification IE, which is used as the IE of on-demand SSB mode indication information. gNB-DU can also provide on-demand SSB mode indication information to gNB-CU through a new IE.

[0396] Step 2-2: gNB-CU replies gNB-DU configuration update response message.

[0397] If the gNB-CU receives the on-demand SSB mode activation indication sent by gNB-DU (i.e. the on-demand SSB mode indication information of the cell information indicating the activation of on-demand SSB mode), for example, the coverage value is set to 0 and the coverage modification cause is set to “on demand SSB mode activation”, the gNB-CU can consider that those related cells or SSB beams enter on-demand SSB mode, determine that these cells cannot serve as PCell, or these SSBs cannot serve as SSBs of PCell serving terminal, and need to inform the neighbor NG-RAN node of this information. If the gNB-CU receives the on-demand SSB mode deactivation indication sent by gNB-DU (i.e. the on-demand SSB mode indication information of the cell information indicating the deactivation of on-demand SSB mode), for example, the coverage value is a non-0 value, the gNB-CU can consider that those related cells or SSB beams leave on-demand SSB mode (i.e. resume normal SSB transmission mode), determine that these cells can serve as PCell again, or these SSBs can serve as SSBs of PCell serving terminal again, and need to inform the neighbor NG-RAN node of this information.

[0398] Step 1 (including step 1-1 and step 1-2) and step 2 (including step 2-1 and step 2-2) are independent of each other, and step 2 can be before or after step 1.

[0399] Step 3-1: The gNB-CU sends the on-demand SSB mode indication information to the neighbor NG-RAN node. The on-demand SSB mode indication information is used to indicate the activation or deactivation of the on-demand SSB mode, and the IE can be at the SSB level or at the cell level. The IE contains at least one of the following information: cell identity, coverage state of the cell, SSB list of the cell, coverage state of each SSB in the SSB list, coverage modification cause (energy saving).

[0400] The gNB-CU can send the NG-RAN node configuration update message to the neighbor NG-RAN node, and the NG-RAN node configuration update message carries the coverage range modification notification IE, which is used as the IE of the on-demand SSB mode indication information. The gNB-CU can also provide the on-demand SSB mode indication information to the neighbor NG-RAN node through a new IE.

[0401] Step 3-2: The neighbor NG-RAN node replies with the NG-RAN node configuration update response message.

[0402] If the coverage modification cause is set to "energy saving", the neighbor NG-RAN node considers that the coverage modification (e.g. coverage value set to 0, or coverage value set to non-0 value) of the related cell or SSB is due to some network energy saving technique. Therefore the neighbor NG-RAN node can need to expand its own coverage to guarantee the access of the terminal, or reduce its own coverage. In the case of coverage value modification to 0, this information can be used to decide to request the related cell or SSB beam of the cell to be activated.

[0403] Example 2: Neighbor NG-RAN node requests to deactivate on-demand SSB mode, gNB-CU and gNB-DU split.

[0404] Figure 4 is an example 2 flowchart provided by the embodiments of the present disclosure, as shown in Figure 4, the first network device includes gNB-CU and gNB-DU, the first network device supports the cell to enter on demand SSB mode, the interaction flow of example 2 includes:

[0405] Step 1-1: Same as step 3-1 of example 1, send on-demand SSB mode activation indication.

[0406] Step 1-2: Same as step 3-2 of example 1, the neighbor NG-RAN node replies NG-RAN node configuration update response message.

[0407] Step 2: The neighbor NG-RAN node receives the on-demand SSB mode activation indication, if the cell of the neighbor NG-RAN node itself is too large, exceeds the preset threshold or is limited by other performance indicators, the neighbor NG-RAN node can request the first network device to deactivate the on demand SSB mode of the cell or SSB, so that the cell in on demand SSB mode returns to the normal cell mode, that is, the on-demand SSB cell can offload part of the load of the neighbor NG-RAN node.

[0408] Step 3: The neighbor NG-RAN node sends the deactivation on-demand SSB mode request information to the gNB-CU. The IE of the deactivation on-demand SSB mode request information can be SSB level or cell level, and the IE at least contains one of the following information: cell list, SSB list. The neighbor NG-RAN node can send the deactivation on-demand SSB mode request information through cell activation request message or NG-RAN node configuration update message.

[0409] If the deactivation on-demand SSB mode request information is contained in the Xn interface message such as the cell activation request message or the NG-RAN node configuration update message, the neighbor NG-RAN node can use the information to decide the related cell or the SSB activation of the related cell if necessary.

[0410] Step 4: The gNB-CU sends the deactivation on-demand SSB mode request information to the gNB-DU.

[0411] The gNB-CU can send a new IE of the deactivation on-demand SSB mode request information through the gNB-CU configuration update message, and the IE contains at least one of the following information: cell list, SSB list.

[0412] If the deactivation on-demand SSB mode request information is contained in the gNB-CU configuration update message, the gNB-DU refers to the information to decide the on-demand SSB mode deactivation of the related cell.

[0413] Step 5: The gNB-DU completes the on-demand SSB mode deactivation of the cell, and the cell changes from the on-demand SSB mode to the normal cell mode.

[0414] Step 6: The gNB-DU sends the on-demand SSB mode indication information to the gNB-CU to indicate the on-demand SSB mode deactivation of the cell. The gNB-DU can send the IE through the gNB-DU configuration update message or the gNB-CU configuration update response message, and the other is the same as step 2-1 of example 1.

[0415] Step 7: The gNB-CU sends the on-demand SSB mode indication information to the neighbor NG-RAN node to indicate the on-demand SSB mode deactivation of the cell. The gNB-CU can send the IE through the cell activation response message or the NG-RAN node configuration update response message. The other is the same as step 3-1 of example 1.

[0416] Example 3: On-demand SIB1 WUS configuration, gNB-CU and gNB-DU separation.

[0417] FIG. 5 is a flowchart of example 3 provided by the embodiments of the present disclosure, as shown in FIG. 5, the first network device includes a gNB-CU and a gNB-DU, the first network device supports the cell entering the on-demand SIB1 mode, the normal cell Cell A is located in the neighbor NG-RAN node, and the neighbor NG-RAN node can include a neighbor gNB-CU and a neighbor gNB-DU. The interaction process of example 3 includes:

[0418] Before on demand SIB1 mode activation or WUS configuration change, the first network device needs to send the WUS configuration to Cell A.

[0419] Step 1-1: The gNB-DU sends the uplink WUS configuration to the gNB-CU. The gNB-DU can send the uplink WUS configuration through the gNB-DU configuration update message.

[0420] Step 1-2: The gNB-CU replies the gNB-DU configuration update response message.

[0421] Step 3-1: The gNB-CU sends the NG-RAN node configuration update message to the neighbor gNB-CU, providing the uplink WUS configuration of the cell served by the first network device.

[0422] Step 3-2: The neighbor gNB-CU replies the NG-RAN node configuration update response message.

[0423] Step 3a-1 (optional): The neighbor gNB-CU sends the uplink WUS configuration to the neighbor gNB-DU. The neighbor gNB-CU can send the uplink WUS configuration through the gNB-CU configuration update message.

[0424] Step 3a-2 (optional): The neighbor gNB-DU replies the gNB-CU configuration update response message.

[0425] Example 4: On demand SIB1 mode indication, gNB-CU and gNB-DU separation.

[0426] FIG. 6 is a flowchart of Example 4 provided by the embodiments of the present disclosure, as shown in FIG. 6, the first network device includes a gNB-CU and a gNB-DU, the first network device supports the cell entering the on demand SIB1 mode, the normal cell Cell A is located at the neighbor NG-RAN node, the interaction flow of Example 4 includes:

[0427] Step 1-1: The gNB-CU sends the gNB-CU configuration update message to the gNB-DU, and carries the cell list allowed to activate the on demand SIB1 mode.

[0428] Step 1-2: The gNB-DU replies the gNB-CU configuration update response message.

[0429] If the IE of the list of cells allowed to activate on demand SIB1 mode is included in the gNB-CU configuration update message, the gNB-DU shall consider that the indicated cells are allowed to deactivate SIB1 within the cells for on demand SIB1 purpose.

[0430] When the on demand SIB1 mode of a cell changes: on demand SIB1 mode activation or on demand SIB1 mode deactivation, the gNB-DU sends on-demand SIB1 mode indication information to the gNB-CU.

[0431] Step 2-1: The gNB-DU sends on-demand SIB1 mode indication information to the gNB-CU.

[0432] Wherein, the on-demand SIB1 mode indication information is used to indicate the activation or deactivation of the on-demand SIB1 mode, the IE can be SSB level or cell level, and the IE contains at least one of the following information: cell identity, on-demand SIB1 mode indication of the cell, SSB list of the cell, on-demand SIB1 mode indication of each SSB in the SSB list. The gNB-DU can send the on-demand SIB1 mode indication information through the gNB-DU configuration update message.

[0433] Step 2-2: The gNB-CU replies to the gNB-DU configuration update response message.

[0434] If the IE of the on-demand SIBI mode indication information is included in the gNB-DU configuration update message, and it indicates the activation of the on-demand SIB1 mode, the gNB-CU shall consider that the related cells or SSB beams enter the on-demand SIB1 mode. Because Cell A needs to broadcast WUS configuration, in addition, these cells cannot serve traditional terminals as PCell, or these SSBs cannot serve traditional terminals as PCell's SSB, it is necessary to inform the neighbor NG-RAN node (including Cell A) of this information.

[0435] If the IE of on-demand SIB1 mode indication information is contained in the gNB-DU configuration update message and indicates to deactivate the on-demand SIB1 mode, the gNB-CU considers that those related cells or SSB beams leave the on-demand SIB1 mode (i.e. resume normal SIB1 transmission mode). Because Cell A can need to stop broadcasting WUS configuration, in addition these cells can re-serve as PCell, or these SSBs can re-serve as SSB of PCell to serve legacy terminals, it is needed to inform the neighbor NG-RAN nodes (including Cell A) of this information.

[0436] Step 1 (including Step 1-1 and Step 1-2) and Step 2 (including Step 2-1 and Step 2-2) are independent of each other, Step 2 can be before or after Step 1.

[0437] Step 3-1: gNB-CU sends on-demand SIB1 mode indication information to neighbor NG-RAN nodes, the IE can be SSB level or cell level, the IE contains at least one of the following information: cell identity, on-demand SIB1 mode indication of cell, SSB list of cell, on-demand SIB1 mode indication of each SSB in SSB list. gNB-CU can send on-demand SIB1 mode indication information through NG-RAN node configuration update message.

[0438] If on-demand SIB1 mode indication information is contained in NG-RAN node configuration update message and its indication activates on-demand SIB1 mode, neighbor NG-RAN nodes can need to broadcast WUS configuration for these cells, or expand their coverage to ensure the access of legacy terminals.

[0439] If on-demand SIB1 mode indication information indicates to deactivate on-demand SIB1 mode, neighbor NG-RAN nodes can stop broadcasting WUS configuration for these cells, or reduce their coverage. In addition, if it indicates to activate on-demand SIB1 mode, neighbor NG-RAN nodes can use this information to decide to request the deactivation of on-demand SIB1 mode of related cells or related SSBs if necessary.

[0440] Optionally, if the CU and DU of the neighbor NG-RAN node are separated, the neighbor NG-RAN node includes a neighbor gNB-CU and a neighbor gNB-DU, after the gNB-CU sends the on-demand SIB1 mode indication information to the neighbor NG-RAN node, the neighbor gNB-CU can send the on-demand SIB1 mode indication information to the neighbor gNB-DU, and the neighbor gNB-CU can send the IE through a gNB-CU configuration update message.

[0441] Step 3-2: The neighbor gNB-DU replies a gNB-CU configuration update response message.

[0442] If the on-demand SIB1 mode indication information is contained in the gNB-CU configuration update message, the gNB-DU can provide the terminal with the uplink WUS configuration of the cell that activates the on-demand SIB1 mode.

[0443] Example 5: The neighbor NG-RAN node requests to deactivate the on-demand SIB1 mode, and the gNB-CU and the gNB-DU are separated.

[0444] FIG. 7 is a flowchart of example 5 provided by the embodiments of the present disclosure, as shown in FIG. 7, the first network device includes a gNB-CU and a gNB-DU, the first network device supports the cell to enter the on-demand SIB1 mode, and the interactive process of example 5 includes:

[0445] Step 1-1: Same as step 3-1 of example 4, indicating the activation of the on-demand SSB mode. After the cell enters the on-demand SIB1 mode, it can serve the terminal of R19, but the traditional terminal cannot access.

[0446] Step 1-2: Same as step 3-2 of example 4, the neighbor gNB-DU replies a gNB-CU configuration update response message.

[0447] Step 2: After the neighbor NG-RAN node receives the indication of the activation of the on-demand SIB1 mode, if the cell of the neighbor NG-RAN node itself has excessive load, the neighbor NG-RAN node can request the first network device to deactivate the on-demand SIB1 mode of the cell or the SSB, so as to make the cell in the on-demand SIB1 mode return to the normal cell mode, that is, to make the on-demand SIB1 cell distribute part of the load of the neighbor NG-RAN node.

[0448] Step 3: The neighbor NG-RAN node sends the deactivation on-demand SIB1 mode request information to the gNB-CU. Wherein, the IE of the deactivation on-demand SIB1 mode request information can be SSB level or cell level, which contains at least one of the following information: cell list, SSB list. The neighbor NG-RAN node can send the deactivation on-demand SIB1 mode request information through the NG-RAN node configuration update message.

[0449] If the deactivation on-demand SIB1 mode request information is contained in the Xn interface message such as the NG-RAN node configuration update message, the neighbor NG-RAN node can use the information to decide the SIB1 activation of the related cell or the related SSB if necessary.

[0450] Step 4: The gNB-CU sends the deactivation on-demand SIB1 mode request information to the gNB-DU.

[0451] The gNB-CU can send a new IE of the deactivation on-demand SIB1 mode request information through the gNB-CU configuration update message, which contains at least one of the following information: cell list, SSB list.

[0452] If the deactivation on-demand SIB1 mode request information is contained in the gNB-CU configuration update message, the gNB-DU can use the information to decide the SIB1 activation of the related cell or the related SSB if necessary.

[0453] Step 5: The gNB-DU completes the on demand SIB1 mode deactivation, and the cell changes from the on demand SIB1 mode to the normal cell mode.

[0454] Step 6: The gNB-DU sends the on-demand SIB1 mode indication information to the gNB-CU, indicating the on-demand SIB1 mode deactivation, which can be sent through the gNB-DU configuration update message or the gNB-CU configuration update response message. Others are the same as steps 2-1 of example 4.

[0455] Step 7: The gNB-CU sends the on-demand SIB1 mode indication information to the neighbor NG-RAN node, indicating the on-demand SIB1 mode deactivation, which can be sent through the NG-RAN node configuration update response message. Others are the same as steps 3-1 of example 4.

[0456] Example 6: SSB adaptive mode indication, gNB-CU and gNB-DU separation.

[0457] Figure 8 is a flowchart of example 6 provided by the embodiments of the present disclosure, as shown in Figure 8, the first network device includes gNB-CU and gNB-DU, the first network device supports the cell entering SSB adaptive mode, the interaction process of example 6 includes:

[0458] Step 1-1: gNB-CU sends the cell list or SSB list allowed to activate SSB adaptive mode to gNB-DU, gNB-CU can carry this IE through gNB-CU configuration update message.

[0459] Step 1-2: gNB-DU replies gNB-CU configuration update response message.

[0460] If the IE of the cell list or SSB list allowed to activate SSB adaptive mode is included in the gNB-CU configuration update message, gNB-DU should consider that the cell or SSB beam in the cell is allowed to enter SSB adaptive mode for the purpose of network energy saving.

[0461] After receiving the cell list allowed to activate SSB adaptive mode sent by gNB-CU, gNB-DU can activate the SSB adaptive mode of the cell. After the cell enters SSB adaptive mode, SSB becomes more sparse, the coverage of SSB changes, the cell changes from PCell to SCell, and cannot support traditional terminal access, and terminals in neighboring cells cannot be handed over to the cell.

[0462] When the SSB adaptive mode of the cell changes: SSB adaptive mode activation or SSB adaptive mode deactivation, gNB-DU sends SSB adaptive mode indication information to gNB-CU.

[0463] Step 2-1: gNB-DU sends SSB adaptive mode indication information to gNB-CU. The SSB adaptive mode indication information is used to indicate the activation or deactivation of SSB adaptive mode, this IE can be SSB level or cell level, and this IE at least contains one of the following information: cell identifier, coverage state of the cell, SSB list of the cell, coverage state of each SSB in the SSB list, coverage modification reason (SSB adaptive mode activation).

[0464] gNB-DU can send gNB-DU configuration update message to gNB-CU, and the gNB-DU configuration update message carries coverage range modification notification IE, which is used as the IE of SSB adaptive mode indication information. gNB-DU can also provide SSB adaptive mode indication information to gNB-CU through a new IE.

[0465] Step 2-2: gNB-CU replies gNB-DU configuration update response message.

[0466] If the gNB-CU receives SSB adaptive mode activation indication (i.e. SSB adaptive mode indication information of cell information used to indicate activation of SSB adaptive mode) sent by gNB-DU, for example, the coverage value is set to 0 and the coverage modification reason is set to "SSB adaptive mode activation", the gNB-CU can consider that those related cells or SSB beams enter SSB adaptive mode, determine that these cells cannot be used as PCell, or these SSBs cannot be used as SSB serving terminals of PCell, and need to inform the neighbor NG-RAN node of this information. If the gNB-CU receives SSB adaptive mode deactivation indication (i.e. SSB adaptive mode indication information of cell information used to indicate deactivation of SSB adaptive mode) sent by gNB-DU, for example, the coverage value is a non-zero value, the gNB-CU can consider that those related cells or SSB beams leave SSB adaptive mode (i.e. resume normal SSB transmission mode), determine that these cells can be used as PCell again, or these SSBs can be used as SSB serving terminals of PCell again, and need to inform the neighbor NG-RAN node of this information.

[0467] Step 1 (including step 1-1 and step 1-2) and step 2 (including step 2-1 and step 2-2) are independent of each other, and step 2 can be before or after step 1.

[0468] Step 3-1: gNB-CU sends SSB adaptive mode indication information to the neighbor NG-RAN node. The SSB adaptive mode indication information is used to indicate the activation or deactivation of SSB adaptive mode. The IE can be SSB level or cell level. The IE contains at least one of the following information: cell identity, coverage state of cell, SSB list of cell, coverage state of each SSB in SSB list, coverage modification reason (energy saving).

[0469] The gNB-CU can send NG-RAN node configuration update message to the neighbor NG-RAN node, and the NG-RAN node configuration update message carries coverage range modification notification IE, which is used as the IE of SSB adaptive mode indication information. The gNB-CU can also provide SSB adaptive mode indication information to the neighbor NG-RAN node through a new IE.

[0470] Step 3-2: the neighbor NG-RAN node replies NG-RAN node configuration update response message.

[0471] If the coverage modification cause is set to "energy saving", the neighbor NG-RAN node considers the coverage modification (e.g. coverage value set to 0, or coverage value set to non-0 value) of the related cell or SSB is due to some network energy saving technique. Therefore the neighbor NG-RAN node can need to expand its own coverage to guarantee the access of the terminal, or reduce its own coverage. In the case of coverage value modification to 0, this information can be used to decide to request the related cell or SSB beam of the cell to be activated.

[0472] Example 7: Neighbor NG-RAN node requests to deactivate SSB adaptive mode, gNB-CU and gNB-DU split.

[0473] Figure 9 is an example 7 flowchart provided by the embodiments of the present disclosure, as shown in Figure 9, the first network device includes gNB-CU and gNB-DU, the first network device supports the cell to enter SSB adaptive mode, the interaction process of example 7 includes:

[0474] Step 1-1: Same as step 3-1 of example 6, send SSB adaptive mode activation indication.

[0475] Step 1-2: Same as step 3-2 of example 6, the neighbor NG-RAN node replies NG-RAN node configuration update response message.

[0476] Step 2: The neighbor NG-RAN node receives the SSB adaptive mode activation indication, if the cell of the neighbor NG-RAN node itself is too large, exceeds the preset threshold or is limited by other performance indicators, the neighbor NG-RAN node can request the first network device to deactivate the SSB adaptive mode of the cell or SSB, so that the cell in the SSB adaptive mode restores to the normal cell mode, that is, the SSB adaptive cell can offload part of the load of the neighbor NG-RAN node.

[0477] Step 3: The neighbor NG-RAN node sends the deactivation SSB adaptive mode request information to the gNB-CU. The IE of the deactivation SSB adaptive mode request information can be SSB level or cell level, which at least contains one of the following information: cell list, SSB list. The neighbor NG-RAN node can send the deactivation SSB adaptive mode request information through the cell activation request message or NG-RAN node configuration update message.

[0478] If the deactivation SSB adaptive mode request information is contained in the Xn interface message such as cell activation request message or NG-RAN node configuration update message, the neighbor NG-RAN node can use the information to decide the related cell or SSB activation of the related cell if necessary.

[0479] Step 4: The gNB-CU sends the deactivation SSB adaptive mode request information to the gNB-DU.

[0480] The gNB-CU can send a new IE of deactivation SSB adaptive mode request information through the gNB-CU configuration update message, which contains at least one of the following information: cell list, SSB list.

[0481] If the deactivation SSB adaptive mode request information is contained in the gNB-CU configuration update message, the gNB-DU refers to this information to decide the SSB adaptive mode deactivation of the related cell.

[0482] Step 5: The gNB-DU completes the SSB adaptive mode deactivation of the cell, and the cell changes from the SSB adaptive mode to the normal cell mode.

[0483] Step 6: The gNB-DU sends the SSB adaptive mode indication information to the gNB-CU to indicate the SSB adaptive mode deactivation of the cell. The gNB-DU can send the IE through the gNB-DU configuration update message or the gNB-CU configuration update response message. The other is the same as step 2-1 of example 1.

[0484] Step 7: The gNB-CU sends the SSB adaptive mode indication information to the neighbor NG-RAN node to indicate the SSB adaptive mode deactivation of the cell. The gNB-CU can send the IE through the cell activation response message or the NG-RAN node configuration update response message. The other is the same as step 3-1 of example 1.
