[0176] The present application provides a method, apparatus, and storage medium for triggering network energy saving. When a base station central unit (gNB-CU) determines that a cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which means deactivating the cell), the gNB-CU releases configuration information about the cell for a terminal device in the cell, or switches the terminal device in the cell to another cell. The gNB-CU then sends first indication information to a base station distributed unit (gNB-DU), where the first indication information is used to instruct the cell to enter an energy-saving state. Thus, the gNB-CU notifies the gNB distributed unit (gNB-DU) through the first indication information that the cell configuration has been released for the terminal device or the terminal device in the cell has been switched to another cell. Alternatively, the base station central unit (gNB-CU) determines that the cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which is to activate Cell DTX / DRX of the cell), and then sends first control information to the terminal equipment in the cell that does not support Cell DTX / DRX of the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal equipment; thereby, the base station central unit (gNB-CU) notifies the base station distribution unit (gNB-DU) through the first indication information that a CHO measurement event based on network energy saving has been configured for the terminal equipment in the cell that does not support Cell DTX / DRX of the cell; and then the base station distribution unit (gNB-DU) can send signaling for instructing the terminal equipment in the cell to trigger a CHO measurement event based on network energy saving, and / or the base station distribution unit (gNB-DU) sends signaling for instructing the terminal equipment in the cell to activate the Cell DTX / DRX function of the cell of the terminal equipment to support Cell DTX / DRX of the cell. Through the above process, when the network equipment determines that a cell needs to enter the energy-saving state, signaling is exchanged between the gNB-CU and the gNB-DU. Both are informed of the cell's energy-saving state, allowing the gNB-DU to ultimately complete the process of achieving network energy saving. This enables the various units of the network equipment to coordinate control of the cell's energy-saving state, thereby achieving the goal of network energy saving.

[0222] The terminal device involved in the embodiments of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called User Equipment (UE).

For example, it may be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges language and / or data with a radio access network.

In some network structures, the network equipment may include a base station centralized unit (CU) node and a base station distributed unit (DU) node. The base station centralized unit and the base station distributed unit may also be arranged geographically separately.

[0224] Network devices and terminal devices can each use one or more antennas for multiple-input, multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO or multi-user MIMO. Depending on the configuration and number of antennas, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO. It can also employ diversity transmission, precoding, or beamforming.

[0225] The terminal device in the embodiment of the present application sends relevant information or similar descriptions to the network side device, which only indicates that the terminal device sends the relevant information in the form of a wireless signal, and its intended recipient is the network device. The network device can obtain the relevant information by receiving the wireless signal.

[0226] The following describes the embodiments of the present application in detail using a 5G system or a 6G system scenario as an example.

[0227] During operation, network equipment (e.g., NR base stations) operates at a large bandwidth; for example, network equipment operates at a bandwidth of 100 MHz. Therefore, network equipment requires a large number of ports and a shorter Transmission Time Interval (TTI); for example, the port is 64T / 64R and the TTI is 1 millisecond (ms). The energy consumption overhead of NR base stations in baseband processing functions, digital front-end processing functions, and other functions is significantly higher than the energy consumption overhead of LTE base stations in these functions. Moreover, the FR2 (Frequency range 2) operating frequency of NR base stations is relatively high, wherein the FR2 operating frequency is greater than 6 gigahertz (GHz); and, the higher the frequency of the NR base station, the greater the path loss of the signal received / sent by the NR base station. Therefore, the NR base station needs to use a narrower beam to transmit the signal farther.

[0228] Therefore, in order to increase the number of NR base stations to transmit signals farther, it is necessary to increase the number of antenna units used for analog beamforming for the NR base station; however, this will lead to an increase in the number of RF units of the NR base station, and the number of RF channels used by the NR base station for sending and receiving signals will also increase. For example, the FR1 band active antenna unit (AAU) used by the NR base station generally uses 192 antenna units and supports 64 RF channels; however, the LTE base station only supports a maximum of 8 RF channels. Since a power amplifier (PA) is provided for each RF channel, the working process of the power amplifier will generate energy consumption; the energy consumption generated by so many power amplifiers will account for about 80% of the energy consumption of the entire NR base station; the more power amplifiers there are, the higher the energy consumption of the NR base station.

[0229] In the actual operation of NR base stations, statistical data shows that the energy consumption of NR base stations is more than three times that of LTE base stations. Therefore, achieving network energy conservation in NR base stations is an urgent problem that needs to be solved.

[0230] In one example, in a 3GPP R15 communication system, to achieve network energy conservation for a base station (e.g., a NR base station), the base station can shut down cells with less traffic or idle cells; and the base station notifies the base stations of adjacent cells that the current cell has been shut down. When the traffic load of an adjacent cell exceeds a certain threshold, the base station of the adjacent cell can request the NR base station that previously shut down the cell to reopen it.

[0231] For example, Figure 1 Schematic diagram of cell switching provided in this application Figure 1 ,like Figure 1As shown, the terminal device 01 is in communication connection with the base station 02 of cell B; the base station 02 can shut down cell B, and the base station 02 notifies the base station 03 of the adjacent cell A that "cell B is shut down".

[0232] Figure 2 Schematic diagram of cell switching provided in this application Figure 2 ,like Figure 2 As shown, after base station 02 notifies base station 03 of adjacent cell A that "cell B is closed", the terminal device 01 communicates with base station 03 of cell A; when the service load of base station 03 of cell A exceeds a certain threshold, base station 03 requests base station 02 to open cell B.

[0233] Figure 3 Schematic diagram of cell switching provided in this application Figure 3 ,like Figure 3 As shown, after base station 03 requests base station 02 to open cell B, base station 02 opens cell B, and the terminal device 01 communicates with base station 02 of cell B.

[0234] In another example, in a communication system prior to the 3GPP R18 communication system, a base station (e.g., an NR base station) can perform discontinuous transmission / reception to save energy overhead of the base station and reduce energy consumption. For example, for a terminal device, the terminal device is configured with discontinuous reception of the terminal device (i.e., DRX of the UE); thereby, the base station stops sending downlink transmissions to the terminal device (e.g., stops sending PDCCH to the terminal device) outside the activation time (active time) of the UE's DRX. For another example, when the base station determines that there is no downlink service, the base station turns off the downlink baseband and RF transmitter outside the transmission time of the common signal.

[0235] The above-mentioned UE DRX is configured for the terminal device. After the UE DRX is configured for the terminal device, the terminal device does not monitor the PDCCH during the UE DRX inactive (off) period; however, the terminal device can still initiate uplink transmissions (for example, PUCCH, RACH, SR, or CG-PUSCH) during the UE DRX inactive (off) period.

[0236] However, the DRX activation times (active times) of different UEs are often asynchronous. "Asynchronous" means that the start and duration of the activation time are different. Therefore, the base station can only shut down the DRX of all UEs in the cell during their inactive time, thereby stopping downlink transmission and uplink reception. However, this results in a shorter energy-saving period for the base station, resulting in poor network energy conservation.

[0237] In another example, in the 3GPP R18 communication system, Cell discontinuous transmission / reception for the cell (i.e., Cell DTX / DRX of the cell) is introduced. During the non-active time of the Cell DTX / DRX of the cell, the base station stops sending / receiving signals and stops sending / receiving channels. After activating the Cell DTX / DRX of the cell, it will affect the terminal device's monitoring of the PDCCH and reception of the downlink SPS, and will restrict the terminal device's behavior of sending SR and CG; however, after activating the Cell DTX / DRX of the cell, it will have no effect on the terminal device in the idle state in the cell, and the terminal device in the idle state in the cell can still perform random access, system broadcast message transmission, paging process and other processing processes.

[0238] The UE's CDRX activation time can be set within the time range of the cell's Cell DTX / DRX activation time; this ensures energy conservation for the terminal device. When the CDRX activation times of all UEs in a cell are synchronized, and when the CDRX activation times of all UEs in a cell are aligned with the cell's Cell DTX / DRX activation time, optimal network energy conservation can be achieved.

[0239] In one approach, for "activating Cell DTX / DRX," the network device triggers a terminal device in the cell to activate Cell DTX / DRX via common L1 signaling. For "deactivating Cell DTX / DRX," the network device triggers a terminal device in the cell to deactivate Cell DTX / DRX via common L1 signaling. The terminal device triggered by the network device is one that has Cell DTX / DRX configured.

[0240] Another way is that for the terminal equipment that accesses the cell after the cell enters the energy-saving state, and for "activating the Cell DTX / DRX of the cell", the network equipment triggers the terminal equipment in the cell through RRC signaling to activate the Cell DTX / DRX of the cell; for the terminal equipment that accesses the cell after the cell enters the energy-saving state, and for "deactivating the Cell DTX / DRX of the cell", the network equipment triggers the terminal equipment in the cell through RRC signaling to deactivate the Cell DTX / DRX of the cell. The terminal equipment triggered by the network equipment is a terminal equipment configured with Cell DTX / DRX. For example, an activationStatus parameter can be added to the configuration parameters of the RRC signaling; if the value of the activationStatus parameter is True, it indicates that the terminal equipment in the triggered cell activates the Cell DTX / DRX of the cell; if the value of the activationStatus parameter is False, it indicates that the terminal equipment in the triggered cell deactivates the Cell DTX / DRX of the cell.

[0241] To save energy on network devices, cells can be controlled to enter an energy-saving state. When a cell enters an energy-saving state, the cell's network equipment can no longer provide services to the terminal devices in the cell. Consequently, the terminal devices must release their cell configuration or be switched to another cell.

[0242] Among them, the terminal device actively switches to the adjacent cell, including the following situations:

[0243] In case 1, when a cell needs to be completely shut down to achieve energy-saving, all terminal devices in the cell need to release their configuration for the cell or be handed over to a neighboring cell. In particular, network energy-saving CHO measurement events (e.g., A3 / A4 / A5) can be configured for terminal devices to enable handover to other cells.

[0244] Case 2: When the cell needs to activate the Cell DTX / DRX of the cell to enable the cell to enter the energy-saving state, the cell cannot provide services for terminal devices that do not support the Cell DTX / DRX of the cell, or the cell cannot provide services for terminal devices that will be affected by the Cell DTX / DRX of the cell. These terminal devices need to release the configuration of the cell or switch from the cell to an adjacent cell so that the cell stops serving these terminal devices. In particular, for terminal devices in the cell that do not support the Cell DTX / DRX of the cell, network energy-saving-based CHO measurement events (for example, A3 / A4 / A5) can be configured to enable the terminal device to switch to other cells. For terminal devices in the cell that support the Cell DTX / DRX of the cell, it is necessary to activate the Cell DTX / DRX of the cell of the terminal device (at this time, the terminal device does not need to switch to other cells).

[0245] First, before a cell enters the energy-saving state, the base station centralized unit needs to release the cell configuration for the terminal device that can no longer be served, switch the terminal device, or configure a CHO measurement event based on network energy saving (for example, A3 / A4 / A5). Then, the base station distributed unit can send control information to activate Cell DTX / DRX to the terminal device that continues to be served and send L1 signaling (DCI2-9) for triggering the CHO measurement event based on network energy saving.

[0246] However, in the split gNB architecture, the gNB-CU and gNB-DU are independent of each other.

[0247] In one example, when the gNB-DU determines that a cell needs to enter an energy-saving state, the gNB-CU is unaware of the need to enter an energy-saving state, and the gNB-CU is unable to perform the relevant operation.

[0248] For example, the gNB-DU decides to deactivate a cell (i.e., shut down the cell), but requires the gNB-CU to switch all devices in the cell to another cell. However, the gNB-CU is unaware of the cell deactivation and is unable to trigger all devices in the cell to release the cell configuration or switch to another cell.

[0249] For another example, the gNB-DU decides to activate Cell DTX / DRX for a cell, but requires the gNB-CU to switch some UEs in the cell to other cells. However, the gNB-CU is unaware of the need to activate Cell DTX / DRX for the cell, and thus the gNB-CU cannot trigger the legacy UEs in the cell to switch to other cells. Furthermore, the gNB-CU cannot release the cell configuration or switch some UEs in the cell (i.e., UEs that do not support Cell DTX / DRX) to other cells.

[0250] In another example, the gNB-CU configures a network energy-saving CHO measurement event for a terminal device in a cell, and the gNB-DU sends control signaling to the terminal device in the cell to trigger the network energy-saving CHO measurement event. However, after the gNB-CU configures the network energy-saving CHO measurement event for the terminal device in the cell, the gNB-DU does not know whether the network energy-saving CHO measurement event has been configured for the terminal device. Consequently, the gNB-DU is unsure when and whether to send control signaling to the terminal device to trigger the network energy-saving CHO measurement event.

[0251] In another example, when the gNB-CU determines that Cell DTX / DRX needs to be activated for a cell, the gNB-CU switches terminal devices in the cell that do not support Cell DTX / DRX to other cells, and the gNB-DU needs to activate Cell DTX / DRX for the terminal devices in the cell that support Cell DTX / DRX. However, when the gNB-CU determines that Cell DTX / DRX needs to be activated for the cell, the gNB-DU is unaware of the need to activate Cell DTX / DRX, and therefore does not know when to activate Cell DTX / DRX for the terminal devices in the cell that support Cell DTX / DRX.

[0252] Therefore, for the split gNB architecture, a method is urgently needed so that when the network device determines that a cell needs to enter an energy-saving state, each unit of the network device can obtain this information and perform related operations, thereby achieving the purpose of collaboratively controlling the cell to enter an energy-saving state.

[0253] Figure 4The scene graph provided for this application, such as Figure 4 As shown, the network equipment provides network services to each of the multiple terminal devices in the cell. The network equipment includes the gNB-CU and the gNB-DU. The gNB-CU and gNB-DU are independent of each other.

[0254] Figure 5 A flowchart of a method for triggering network energy saving according to an embodiment of the present application is shown in FIG. Figure 5 As shown, an embodiment of the present application provides a method for triggering network energy saving, which can be applied to the base station centralized unit (gNB-CU) of the network device in the aforementioned 5G / 6G system structure, so that when it is determined that a cell needs to enter an energy-saving state, each unit of the network device can obtain the information (i.e., the cell needs to enter an energy-saving state) and perform related operations, that is, the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) can obtain the information and perform related operations, so that each unit of the network device controls the cell to enter an energy-saving state, thereby achieving the purpose of collaboratively controlling the cell to enter an energy-saving state. The method provided in this embodiment includes the following steps:

[0255] Step 501: The base station centralized unit determines that the cell needs to enter the energy-saving state, releases the configuration information about the cell of the terminal equipment in the cell, or sends first control information to the terminal equipment in the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal equipment.

[0256] In this embodiment, in a split gNB architecture, the network device includes a base station centralized unit (gNB-CU) and a base station distributed unit (gNB-DU), wherein the gNB-CU and the gNB-DU are independent of each other.

[0257] The gNB-CU can perform its own detection to determine whether a cell needs to enter an energy-saving state. Alternatively, the gNB-DU can notify the gNB-CU of the need for a cell to enter an energy-saving state. The gNB-CU can then determine whether a cell needs to enter an energy-saving state.

[0258] When the gNB-CU determines that a cell needs to enter an energy-saving state, the gNB-CU needs to switch the terminal devices in the cell to other cells.

[0259] Method 1: When the gNB-CU determines that a cell needs to enter an energy-saving state, if the energy-saving state is specifically deactivating the cell (i.e., shutting down the cell), the gNB-CU needs to handover all devices in the cell to another cell. The gNB-CU releases the cell configuration for all devices in the cell or sends a handover command to each device in the cell, instructing the devices to handover to another cell. The gNB-CU also releases the cell configuration information for the devices in the cell. In other words, the gNB-CU needs to perform handover and cell release operations.

[0260] For example, if the cell to be deactivated is the PCell of a terminal device, the gNB-CU will hand over the terminal device in the cell to another cell. If the cell to be deactivated is the PCell or SCell of a terminal device, the gNB-CU will release the configuration information of the terminal device in the cell.

[0261] Method 2: When the gNB-CU determines that a cell needs to enter an energy-saving state, if the "cell needs to enter an energy-saving state" specifically involves activating Cell DTX / DRX in the cell, the gNB-CU sends first control information to terminal devices in the cell that do not support Cell DTX / DRX. The first control information is used to configure a network energy-saving CHO measurement event for the terminal devices. In other words, in this case, the gNB-CU configures a network energy-saving CHO measurement event for terminal devices in the cell that do not support Cell DTX / DRX.

[0262] Step 502: The base station centralized unit sends first indication information to the base station distributed unit of the network device. The first indication information is used to instruct the cell to enter the energy-saving state.

[0263] In this embodiment, after the base station centralized unit (gNB-CU) determines to deactivate a cell (i.e., shut down the cell), and then releases the configuration information about the cell for the terminal equipment in the cell, the base station centralized unit (gNB-CU) needs to inform the base station distributed unit (gNB-DU) that the cell enters the energy-saving state; at this time, the base station centralized unit (gNB-CU) sends a first indication message to the base station distributed unit (gNB-DU), and the first indication message is used to instruct the cell to enter the energy-saving state.

[0264] After the gNB-CU determines that Cell DTX / DRX needs to be activated for a cell, and then releases the cell configuration for out-of-service terminal devices or switches these terminal devices to other cells, the gNB-CU needs to notify the gNB-DU to instruct the gNB-DU to complete the subsequent configuration process. At this time, the gNB-CU sends a first indication message to the gNB-DU, which is used to instruct the cell to enter the energy-saving state. Thus, after the base station distribution unit (gNB-DU) receives the first indication information, the base station distribution unit (gNB-DU) sends a signaling for instructing the terminal device in the cell that does not support the Cell DTX / DRX of the cell to trigger a CHO measurement event based on network energy saving; and / or, after the base station distribution unit (gNB-DU) receives the first indication information, the base station distribution unit (gNB-DU) sends a signaling for instructing the terminal device in the cell that supports the Cell DTX / DRX of the cell to activate the Cell DTX / DRX function of the cell.

[0265] In this embodiment, the base station centralized unit (gNB-CU) determines that a cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which means deactivating the cell), and then releases the configuration information about the cell for the terminal device in the cell, or switches the terminal device in the cell to another cell; then, the base station centralized unit (gNB-CU) sends first indication information to the base station distributed unit (gNB-DU), and the first indication information is used to instruct the cell to enter an energy-saving state; thereby, the base station centralized unit (gNB-CU) informs the base station distributed unit (gNB-DU) through the first indication information that the cell configuration has been released for the terminal device or the terminal device in the cell has been switched to another cell. Alternatively, the base station central unit (gNB-CU) determines that the cell needs to enter the energy-saving state (in this case, the cell needs to enter the energy-saving state, which means activating the Cell DTX / DRX of the cell), and then sends first control information to the terminal equipment in the cell that does not support the Cell DTX / DRX of the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal equipment; thereby, the base station central unit (gNB-CU) notifies the base station distribution unit (gNB-DU) through the first indication information that the CHO measurement event based on network energy saving has been configured for the terminal equipment in the cell that does not support the Cell DTX / DRX of the cell; and then the base station distribution unit (gNB-DU) can send signaling for instructing the terminal equipment to trigger the CHO measurement event based on network energy saving, and / or the base station distribution unit (gNB-DU) can send signaling for instructing the terminal equipment to activate the Cell DTX / DRX function of the cell of the terminal equipment to support the Cell DTX / DRX of the cell. Through the above process, when the network equipment determines that a cell needs to enter the energy-saving state, signaling is exchanged between the gNB-CU and the gNB-DU. Both are informed of the cell's energy-saving state, allowing the gNB-DU to ultimately complete the process of achieving network energy saving. This enables the various units of the network equipment to coordinate control of the cell's energy-saving state, thereby achieving the goal of network energy saving.

[0266] Figure 6 A signaling diagram of a method for triggering network energy saving provided in an embodiment of the present application is shown in FIG. Figure 6As shown, an embodiment of the present application provides a method for triggering network energy saving, which can be applied to the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) of the network device in the aforementioned 5G / 6G system structure, so that when it is determined that a cell needs to enter an energy-saving state, each unit of the network device can obtain the information (that is, the cell needs to enter an energy-saving state) and perform related operations, that is, the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) can obtain the information and perform related operations, so that each unit of the network device controls the cell to enter an energy-saving state, thereby achieving the purpose of collaboratively controlling the cell to enter an energy-saving state. The method provided in this embodiment includes the following steps:

[0267] Step 601: The base station centralized unit receives a request message sent by the base station distributed unit; wherein the request message is used to request the cell to enter an energy-saving state.

[0268] In this embodiment, in a split gNB architecture, the network device includes a base station centralized unit (gNB-CU) and a base station distributed unit (gNB-DU), wherein the gNB-CU and the gNB-DU are independent of each other.

[0269] The gNB-DU determines whether a cell needs to enter the energy-saving state. If so, the gNB-DU sends a request to the gNB-CU requesting the cell to enter the energy-saving state.

[0270] The request information may also be referred to as a network energy-saving request.

[0271] Therefore, when the gNB-DU decides whether a cell needs to enter an energy-saving state, the gNB-DU informs the gNB-CU that the cell needs to enter an energy-saving state. The gNB-CU then learns that the cell needs to enter an energy-saving state, and the gNB-CU can trigger the terminal device in the cell to release the terminal device's configuration regarding the cell, or switch the terminal device in the cell to another cell.

[0272] In an optional embodiment, the request information includes information for requesting deactivation of a cell, or the request information includes information for requesting activation of Cell DTX / DRX of the cell.

[0273] In this embodiment, the gNB-DU determines whether a cell needs to enter an energy-saving state. If the gNB-DU determines that the cell needs to enter an energy-saving state, and the gNB-DU determines that the cell needs to enter an energy-saving state is to be deactivated, the gNB-DU sends a request message to the gNB-CU. The request message includes information requesting cell deactivation (i.e., the request message includes information requesting cell shutdown). Specifically, the request message indicates that the cell needs to enter an energy-saving state, and the request message indicates cell deactivation.

[0274] Alternatively, the gNB-DU determines whether the cell needs to enter the energy-saving state. If the gNB-DU determines that the cell needs to enter the energy-saving state, and the gNB-DU determines that "the cell needs to enter the energy-saving state" means activating Cell DTX / DRX for the cell, the gNB-DU sends a request message to the gNB-CU. The request message includes information requesting activation of Cell DTX / DRX for the cell. In other words, the request message indicates that the cell needs to enter the energy-saving state, and the request message indicates activation of Cell DTX / DRX for the cell.

[0275] The gNB-DU uses a request message to inform the gNB-CU whether it needs to deactivate a cell (i.e., shut down the cell) or activate Cell DTX / DRX. The gNB-CU then learns that the cell needs to enter an energy-saving state. The gNB-CU then triggers the terminal devices in the cell to release their cell configuration or switch them to another cell.

[0276] In an optional embodiment, the request information includes type information of Cell DTX / DRX of the cell;

[0277] The request information is used to request activation of Cell discontinuous transmission of the cell, or to request activation of Cell discontinuous reception of the cell, or to request simultaneous activation of Cell discontinuous transmission of the cell and Cell discontinuous reception of the cell.

[0278] In this embodiment, the request information sent by the base station distribution unit (gNB-DU) to the base station central unit (gNB-CU) may include the type information of Cell DTX / DRX of the cell.

[0279] For example, the type information of the Cell DTX / DRX of the cell is Cell discontinuous transmission (Cell DTX) of the cell; then, the request information is used to request activation of the Cell discontinuous transmission of the cell.

[0280] The type information of the Cell DTX / DRX of the cell is Cell discontinuous reception (Cell DRX) of the cell; therefore, the request information is used to request activation of the Cell discontinuous reception of the cell.

[0281] The type information of the Cell DTX / DRX of the cell is Cell discontinuous transmission / reception (Cell DTX / DRX) of the cell; therefore, the request information is used to request simultaneous activation of the Cell discontinuous transmission and the Cell discontinuous reception of the cell.

[0282] Therefore, when the base station distribution unit (gNB-DU) determines that a cell needs to enter the energy-saving state, the base station distribution unit (gNB-DU) notifies the base station central unit (gNB-CU) that the cell needs to enter the energy-saving state, and the base station distribution unit (gNB-DU) notifies the base station central unit (gNB-CU) of the cell's Cell DTX / DRX type information.

[0283] In an optional embodiment, step 601 includes the following process: the base station centralized unit receives the second F1 application protocol signaling sent by the base station distributed unit, wherein the second F1 application protocol signaling includes request information.

[0284] In this embodiment, the gNB-DU determines whether the cell needs to enter the energy-saving state. If the gNB-DU determines that the cell needs to enter the energy-saving state, the gNB-DU sends a second F1 application protocol signaling (second F1AG signaling) to the gNB-CU. The second F1 application protocol signaling includes the above-mentioned request information.

[0285] Furthermore, the request information is carried by the second F1AG signaling. That is, the request information can be a separate signaling, or the request information can be sent to the base station centralized unit (gNB-CU) via F1AG signaling.

[0286] The second F1 application protocol signaling may also be referred to as a GNB-DU CONFIGURATION UPDATE message. Table 1 shows the second F1 application protocol signaling.

[0287]

[0288]

[0289] Table 1 Second F1 application protocol signaling

[0290] As shown in Table 1, in the second F1 application protocol signaling (GNB-DU CONFIGURATION UPDATE message), a group name (IE / Group Name) is added as "NES State Required", and "NES State Required" is used to indicate the above request information. Among them, the Presence of the request information is 0. The type of the request information (IE type and reference) is "ENUMERATED (switched off, cell DTXDRX...)". The semantics description of the request information is "Requirement of the cells entering NES state." This semantic description indicates whether to deactivate the cell or activate the Cell DTX / DRX of the cell.

[0291] Step 602: The base station centralized unit sends a second response message to the base station distributed unit; wherein the second response message is used to indicate receipt of the request message.

[0292] In this embodiment, after the gNB-CU receives the second F1 application protocol signaling (second F1AG signaling) sent by the gNB-DU, the gNB-CU needs to feed back a second response message to the gNB-DU to inform the gNB-DU of receipt of the request message.

[0293] The second response information may also be referred to as a GNB-DU CONFIGURATION UPDATE ACKNOWLEDGE message.

[0294] Step 603: The base station centralized unit determines that the cell needs to enter an energy-saving state, releases the configuration information about the cell of the terminal device in the cell, or sends first control information to the terminal device in the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal device.

[0295] In this embodiment, in Case 1, the gNB-CU receives a request from the gNB-DU indicating that a cell needs to enter an energy-saving state and that the cell needs to be deactivated (i.e., shut down). The gNB-CU then releases the cell configuration for all UEs in the cell or sends a handover command to each UE in the cell. In this case, the gNB-CU releases the cell configuration for each UE in the cell. Specifically, the gNB-CU sends first control information to each UE in the cell, thereby configuring a network energy-saving CHO measurement event for each UE.

[0296] Case 2: The gNB-CU receives a request from the gNB-DU indicating that a cell needs to enter a power-saving state and activating Cell DTX / DRX for the cell. The gNB-CU then releases the cell configuration for any terminal in the cell that does not support Cell DTX / DRX, or sends a handover command to any terminal in the cell that does not support Cell DTX / DRX. In this case, the gNB-CU releases the cell configuration for each terminal in the cell. Specifically, the gNB-CU sends first control information to any terminal in the cell that does not support Cell DTX / DRX (i.e., to any terminal in the cell that supports Network Power Saving (CHO)), thereby configuring a Network Power Saving (CHO) measurement event for the terminal.

[0297] Among them, the terminal device supporting network energy-saving CHO means that the terminal device supports the network energy-saving CHO capability, that is, the terminal device supports the "triggering terminal device measurement event based on network energy-saving CHO" triggered by downlink control information (for example, DCI 2-9).

[0298] In an optional embodiment, the second F1 application protocol signaling also includes preset time information, and the preset time information is used to request the base station central unit to complete the release of the configuration information about the cell of the terminal equipment in the cell before the preset time information, or the preset time information is used to request the base station central unit to send the first control information to the terminal equipment in the cell before the preset time information.

[0299] In this embodiment, the second F1 application protocol signaling sent by the gNB-DU to the gNB-CU includes the request information and a preset time. The preset time is the time when the cell enters the energy-saving state.

[0300] For example, the preset time information includes: the system frame number or subframe number for entering the energy-saving state, and how long it will take for the cell to enter the energy-saving state after the base station centralized unit (gNB-CU) receives the request information.

[0301] Therefore, after the base station centralized unit (gNB-CU) obtains the preset time information, the base station centralized unit (gNB-CU) needs to complete the release of the cell configuration information of the terminal equipment in the cell before the preset time information; and then the base station distributed unit (gNB-DU) assumes that the base station centralized unit (gNB-CU) has completed the release of the cell configuration information of the terminal equipment in the cell before the preset time information.

[0302] Alternatively, after the gNB-CU obtains the preset time information, the gNB-CU needs to configure a CHO measurement event based on network energy saving for the terminal devices in the cell that do not support Cell DTX / DRX before the preset time information; and then the gNB-DU assumes that the gNB-CU has configured a CHO measurement event based on network energy saving for the terminal devices in the cell that do not support Cell DTX / DRX before the preset time information.

[0303] Thus, the base station distribution unit (gNB-DU) informs the base station central unit (gNB-CU) of a preset time information, so that both the base station distribution unit (gNB-DU) and the base station central unit (gNB-CU) determine that the task of releasing the terminal device's cell configuration information has been completed before the preset time information; or, both the base station distribution unit (gNB-DU) and the base station central unit (gNB-CU) determine that the task of configuring a network energy-saving-based CHO measurement event for the terminal device has been completed before the preset time information.

[0304] Step 604: The base station centralized unit sends first indication information to the base station distributed unit of the network device. The first indication information is used to instruct the cell to enter the energy-saving state.

[0305] In this embodiment, after the base station centralized unit (gNB-CU) determines to deactivate a cell (i.e., shut down the cell), and then releases the configuration information about the cell for the terminal equipment in the cell, the base station centralized unit (gNB-CU) needs to inform the base station distributed unit (gNB-DU) that the cell enters the energy-saving state; at this time, the base station centralized unit (gNB-CU) sends a first indication message to the base station distributed unit (gNB-DU), and the first indication message is used to instruct the cell to enter the energy-saving state.

[0306] After the gNB-CU determines that Cell DTX / DRX needs to be activated for a cell, and then releases the cell configuration for out-of-service terminal devices or switches these terminal devices to other cells, the gNB-CU needs to notify the gNB-DU to instruct the gNB-DU to complete the subsequent configuration process. At this time, the gNB-CU sends a first indication message to the gNB-DU, which is used to instruct the cell to enter the energy-saving state. Thus, after the base station distribution unit (gNB-DU) receives the first indication information, the base station distribution unit (gNB-DU) sends a signaling for instructing the terminal device in the cell that does not support the Cell DTX / DRX of the cell to trigger a CHO measurement event based on network energy saving; and / or, after the base station distribution unit (gNB-DU) receives the first indication information, the base station distribution unit (gNB-DU) sends a signaling for instructing the terminal device in the cell that supports the Cell DTX / DRX of the cell to activate the Cell DTX / DRX function of the cell.

[0307] In an optional embodiment, the first indication information includes type information of Cell DTX / DRX of the cell; wherein the first indication information is used to indicate the Cell discontinuous transmission of the activated cell, or to indicate the Cell discontinuous reception of the activated cell, or to indicate the Cell discontinuous transmission of the activated cell and the Cell discontinuous reception of the activated cell at the same time.

[0308] In this embodiment, the first indication information sent by the base station centralized unit (gNB-CU) to the base station distributed unit (gNB-DU) may include the type information of Cell DTX / DRX of the cell.

[0309] For example, the type information of the Cell DTX / DRX of the cell is Cell discontinuous transmission (Cell DTX) of the cell; then, the request information is used to request activation of the Cell discontinuous transmission of the cell.

[0310] The type information of the Cell DTX / DRX of the cell is Cell discontinuous reception (Cell DRX) of the cell; therefore, the request information is used to request activation of the Cell discontinuous reception of the cell.

[0311] The type information of the Cell DTX / DRX of the cell is Cell discontinuous transmission / reception (Cell DTX / DRX) of the cell; therefore, the request information is used to request simultaneous activation of the Cell discontinuous transmission and the Cell discontinuous reception of the cell.

[0312] Therefore, when the base station centralized unit (gNB-CU) determines that a cell needs to enter the energy-saving state, the base station centralized unit (gNB-CU) notifies the base station distributed unit (gNB-DU) that the cell needs to enter the energy-saving state, and the base station centralized unit (gNB-CU) notifies the base station distributed unit (gNB-DU) of the cell's Cell DTX / DRX type information.

[0313] Step 605: The base station distribution unit causes the cell to enter an energy-saving state according to the first instruction information.

[0314] In this embodiment, after the base station distribution unit (gNB-DU) receives the first indication information, if it has previously been determined that the cell is to be deactivated (i.e., shut down), the base station distribution unit (gNB-DU) deactivates the cell, thereby causing the cell to enter an energy-saving state.

[0315] Alternatively, after the base station distribution unit (gNB-DU) receives the first indication information, if it has previously been determined that Cell DTX / DRX of the cell needs to be activated, the base station distribution unit (gNB-DU) sends second control information to the terminal device in the cell that does not support Cell DTX / DRX of the cell. The second control information is used to indicate a network energy-saving-based CHO measurement event that triggers the terminal device.

[0316] In an optional embodiment, step 605 includes the following implementations:

[0317] A first implementation of step 605 includes:

[0318] Step 1: The base station distribution unit sends second control information to the terminal equipment in the cell after the preset time information; wherein the second control information is used to indicate a CHO measurement event based on network energy saving that triggers the terminal equipment.

[0319] Step 2: The base station distribution unit sends third control information to the terminal equipment in the cell after the preset time information, wherein the third control information is used to instruct to activate the Cell DTX / DRX function of the cell of the terminal equipment.

[0320] A first implementation of step 605 includes:

[0321] The first indication information is also used to instruct the base station distribution unit to send second control information to the terminal equipment in the cell; then step 605 includes:

[0322] Step 3: The base station distribution unit sends second control information to the terminal equipment in the cell; wherein the second control information is used to indicate a CHO measurement event based on network energy saving that triggers the terminal equipment.

[0323] Step 4: The base station distribution unit sends third control information to the terminal equipment in the cell, wherein the third control information is used to instruct activation of the Cell DTX / DRX function of the cell of the terminal equipment.

[0324] In this embodiment, the first implementation of step 605 is introduced as follows.

[0325] The gNB-DU has sent a preset time to the gNB-CU. The gNB-CU is required to release the cell configuration information for the terminal devices in the cell before the preset time. The gNB-DU assumes that the cell configuration information has been released before the preset time. Therefore, the gNB-DU deactivates the cell (i.e., shuts it down) after the preset time.

[0326] Alternatively, the gNB-DU has already sent the preset time information to the gNB-CU. Consequently, the gNB-CU needs to configure a network energy-saving CHO measurement event for terminal devices in the cell that do not support Cell DTX / DRX before the preset time information. The gNB-DU assumes that the gNB-CU has configured the network energy-saving CHO measurement event for terminal devices in the cell that do not support Cell DTX / DRX before the preset time information. Consequently, the gNB-DU sends second control information to the terminal devices in the cell that do not support Cell DTX / DRX after the preset time information. The second control information is used to indicate triggering of the network energy-saving CHO measurement event for the terminal devices, thereby triggering the network energy-saving CHO measurement event for the terminal devices that do not support Cell DTX / DRX. After the preset time information, the base station distribution unit (gNB-DU) sends third control information to the terminal device in the cell that supports Cell DTX / DRX of the cell, where the third control information is used to indicate the activation of the Cell DTX / DRX function of the cell of the terminal device; thereby triggering the CHO measurement event of the terminal device that supports Cell DTX / DRX of the cell.

[0327] The second implementation of step 605 is introduced as follows.

[0328] The first indication information sent by the gNB-CU to the gNB-DU also instructs the gNB-DU to send second control information to terminal devices in the cell. In this case, the gNB-DU may ignore the preset time information, regardless of whether it exists.

[0329] Furthermore, upon receiving the first indication message from the gNB-CU, the gNB-DU determines that the gNB-CU has completed releasing the cell configuration information for the terminal devices in the cell. Consequently, upon receiving the first indication message, the gNB-DU deactivates the cell (i.e., shuts down the cell).

[0330] Alternatively, after receiving the first indication message sent by the gNB-CU, the gNB-DU determines that the gNB-CU has configured a network energy-saving CHO measurement event for a terminal device in the cell that does not support Cell DTX / DRX. Consequently, after receiving the first indication message, the gNB-DU sends second control information to the terminal devices in the cell that do not support Cell DTX / DRX. The second control information indicates triggering the network energy-saving CHO measurement event for the terminal devices, thereby triggering the network energy-saving CHO measurement event for the terminal devices that do not support Cell DTX / DRX. After receiving the first indication message, the gNB-DU sends third control information to the terminal devices in the cell that support Cell DTX / DRX. The third control information indicates activation of the Cell DTX / DRX function for the terminal devices, thereby triggering the CHO measurement event for the terminal devices that support Cell DTX / DRX.

[0331] Therefore, after the base station distribution unit (gNB-DU) receives the first indication information sent by the base station central unit (gNB-CU), the base station distribution unit (gNB-DU) can determine that the base station central unit (gNB-CU) has configured a CHO measurement event based on network energy saving for the terminal device, and then the base station distribution unit (gNB-DU) sends control signaling (i.e., sends second control information) for triggering the CHO measurement event based on network energy saving to the terminal device that does not support the cell's Cell DTX / DRX; and then, triggers the CHO measurement event based on network energy saving for the terminal device that does not support the cell's Cell DTX / DRX.

[0332] Therefore, after the base station distribution unit (gNB-DU) receives the first indication information sent by the base station central unit (gNB-CU), the base station distribution unit (gNB-DU) can determine that the Cell DTX / DRX of the cell needs to be activated, and then the base station distribution unit (gNB-DU) sends signaling (i.e., sends third control information) to the terminal device in the cell that supports the Cell DTX / DRX of the cell to instruct the activation of the Cell DTX / DRX function of the cell of the terminal device; thereby activating the Cell DTX / DRX function of the cell of the terminal device that supports the Cell DTX / DRX of the cell.

[0333] The second control information may be carried in the downlink control information. For example, the downlink control information is DCI2-9, that is, the downlink control information is L1 signaling for indicating a CHO measurement event based on network energy saving that triggers the terminal device.

[0334] The third control information may be carried in RRC signaling. For example, an activationStatus parameter may be added to the configuration parameters of the RRC signaling; if the value of the activationStatus parameter is True, it indicates that the terminal device in the triggered cell activates the Cell DTX / DRX of the cell; if the value of the activationStatus parameter is False, it indicates that the terminal device in the triggered cell deactivates the Cell DTX / DRX of the cell.

[0335] The cell DTX / DRX configuration information of the cell may include one or more of the following: an activation time cycle (Cycle), an activation time start offset (Start offset), and an activation time duration (On duration). The activation time timer of the cell DTX / DRX is periodically started every activation time cycle.

[0336] The activation time and inactivation time of the Cell DTX / DRX of the cell may be determined through the activation time duration (on duration) and the activation time start offset (start offset).

[0337] Where [(SFN*10)+subframe number] modulo(cellDTX-Cycle)=cellDTX-StartOffset. Here, cellDTX-Cycle is the activation period, and cellDTX-StartOffset is the activation start offset. Both cellDTX-Cycle and cellDTX-StartOffset are in subframe units. SFN is the system frame number. Subframe number is the frame number.

[0338] in, Figure 7 A schematic diagram of the inactive time of Cell DTX / DRX of a cell provided in this application is shown as follows: Figure 7 As shown, the activation time cycle (Cycle) includes: the activation time duration (on duration) of the Cell DTX / DRX of the cell, and the non-active time (non-active time) of the Cell DTX / DRX of the cell.

[0339] In this embodiment, the gNB-CU receives a request message from the gNB-DU requesting that a cell enter an energy-saving state. The gNB-DU then notifies the gNB-CU that the cell needs to enter an energy-saving state. The gNB-CU is informed of the energy-saving state and can trigger the release of terminal device configurations for the cell or handover of the terminal device to another cell. The gNB-CU then sends a second response message to the gNB-DU to notify the gNB-DU of receipt of the request message.

[0340] Then, the base station centralized unit (gNB-CU) determines that the cell needs to enter the energy-saving state (in this case, the cell needs to enter the energy-saving state, which means deactivating the cell), and releases the configuration information about the terminal device in the cell, or switches the terminal device in the cell to another cell; then, the base station centralized unit (gNB-CU) sends a first indication message to the base station distributed unit (gNB-DU), and the first indication message is used to indicate that the cell enters the energy-saving state; thereby, the base station centralized unit (gNB-CU) informs the base station distributed unit (gNB-DU) that the terminal device in the cell has been switched to another cell. Alternatively, the base station central unit (gNB-CU) determines that the cell needs to enter the energy-saving state (in this case, the cell needs to enter the energy-saving state, which means activating the CellDTX / DRX of the cell), and then sends first control information to the terminal equipment in the cell that does not support the CellDTX / DRX of the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal equipment; thereby, the base station central unit (gNB-CU) informs the base station distribution unit (gNB-DU) that the CHO measurement event based on network energy saving has been configured for the terminal equipment in the cell that does not support the CellDTX / DRX of the cell; and then the base station distribution unit (gNB-DU) can send signaling for instructing the terminal equipment to trigger the CHO measurement event based on network energy saving, and / or the base station distribution unit (gNB-DU) sends signaling for instructing the terminal equipment to activate the CellDTX / DRX function of the cell of the terminal equipment to support the CellDTX / DRX of the cell. Through the above process, when the network equipment determines that a cell needs to enter the energy-saving state, signaling is exchanged between the gNB-CU and the gNB-DU. Both are informed of the cell's energy-saving state, allowing the gNB-DU to ultimately complete the process of achieving network energy saving. This enables the various units of the network equipment to coordinate control of the cell's energy-saving state, thereby achieving the goal of network energy saving.

[0341] Figure 8 A signaling diagram of a method for triggering network energy saving provided in an embodiment of the present application is shown in FIG. Figure 8As shown, an embodiment of the present application provides a method for triggering network energy saving, which can be applied to the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) of the network device in the aforementioned 5G / 6G system structure, so that when it is determined that a cell needs to enter an energy-saving state, each unit of the network device can obtain the information (that is, the cell needs to enter an energy-saving state) and perform related operations, that is, the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) can obtain the information and perform related operations, so that each unit of the network device controls the cell to enter an energy-saving state, thereby achieving the purpose of collaboratively controlling the cell to enter an energy-saving state. The method provided in this embodiment includes the following steps:

[0342] Step 801: The base station centralized unit determines that the cell needs to enter the energy-saving state, releases the configuration information about the cell of the terminal device in the cell, or sends first control information to the terminal device in the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal device.

[0343] In this embodiment, in a split gNB architecture, the network device includes a base station centralized unit (gNB-CU) and a base station distributed unit (gNB-DU), wherein the gNB-CU and the gNB-DU are independent of each other.

[0344] The gNB-CU determines whether the cell needs to enter the energy-saving state.

[0345] The base station centralized unit (gNB-CU) determines whether a cell needs to enter an energy-saving state in the following two ways.

[0346] The first method: The base station centralized unit (gNB-CU) determines whether the cell needs to enter the energy-saving state.

[0347] The second method: The gNB-DU determines whether a cell should enter the energy-saving state. If so, the gNB-DU sends a request to the gNB-CU, requesting the cell enter the energy-saving state. The gNB-CU then determines that the cell should enter the energy-saving state.

[0348] Then, when the base station centralized unit (gNB-CU) determines that the cell needs to enter the energy-saving state, the following process is performed.

[0349] If the gNB-CU determines that a cell needs to enter an energy-saving state, and the energy-saving state is a deactivated cell (i.e., a cell shutdown), the gNB-CU releases the cell configuration for all terminal devices in the cell or sends a handover command to all terminal devices in the cell. In this case, the gNB-CU releases the cell configuration information for each terminal device in the cell. Specifically, the gNB-CU sends first control information to each terminal device in the cell, thereby configuring a network energy-saving CHO measurement event for each terminal device.

[0350] If the gNB-CU determines that the cell needs to enter an energy-saving state, and the "energy-saving state" is to activate Cell DTX / DRX of the cell, the gNB-CU releases the cell configuration for the terminal devices in the cell that do not support Cell DTX / DRX, or sends a switching command to the terminal devices in the cell that do not support Cell DTX / DRX. At this time, the gNB-CU releases the cell configuration information for each terminal device in the cell; in particular, the gNB-CU sends first control information to the terminal devices in the cell that do not support Cell DTX / DRX (i.e., to the terminal devices in the cell that support network energy saving CHO), thereby configuring a CHO measurement event based on network energy saving for the terminal devices.

[0351] Among them, the terminal device supporting network energy-saving CHO means that the terminal device supports the network energy-saving CHO capability, that is, the terminal device supports the "triggering terminal device measurement event based on network energy-saving CHO" triggered by downlink control information (for example, DCI 2-9).

[0352] Step 802: The base station centralized unit sends a first F1 application protocol signaling to the base station distributed unit. The first F1 application protocol signaling includes first indication information, which is used to instruct the cell to enter an energy-saving state. The first indication information is also used to instruct the base station distributed unit to send second control information to terminal devices in the cell.

[0353] In an optional embodiment, the first indication information includes information for indicating a deactivated cell, or the first indication information includes information for indicating Cell DTX / DRX of an activated cell.

[0354] In this embodiment, after the gNB-CU executes step 801, the gNB-CU sends a first F1 application protocol signaling (first F1AG signaling) to the gNB-DU. The first F1 application protocol signaling includes first indication information. The first indication information is used to instruct the cell to enter the energy-saving state.

[0355] Furthermore, the first indication information is carried via the first F1AG signaling. That is, the first indication information may be a separate signaling, or the first indication information may be sent to the base station distribution unit (gNB-DU) via the F1AG signaling.

[0356] Among them, if the base station centralized unit (gNB-CU) determines by itself whether the cell needs to enter the energy-saving state, then if the base station centralized unit (gNB-CU) determines that the cell needs to enter the energy-saving state, and the "energy-saving state" is to deactivate the cell, then after the base station centralized unit (gNB-CU) executes step 801, the base station centralized unit (gNB-CU) sends a first F1 application protocol signaling to the base station distributed unit (gNB-DU), and the first F1 application protocol signaling includes first indication information, and the first indication information includes an information, which is used to indicate the deactivation of the cell (that is, the first indication information indicates the deactivation of the cell).

[0357] If the gNB-CU determines whether the cell needs to enter the energy-saving state, then if the gNB-CU determines that the cell needs to enter the energy-saving state, and the "energy-saving state" is to activate the Cell DTX / DRX of the cell, then after the gNB-CU executes step 801, the gNB-CU sends a first F1 application protocol signaling to the gNB-DU. The first F1 application protocol signaling includes first indication information, and the first indication information includes information for indicating the Cell DTX / DRX of the activated cell (i.e., the first indication information indicates the Cell DTX / DRX of the activated cell).

[0358] Therefore, when the base station centralized unit (gNB-CU) determines that a cell needs to enter an energy-saving state, after the base station centralized unit (gNB-CU) releases the cell configuration for a terminal device in the cell or sends a handover command to the terminal device in the cell, or after the base station centralized unit (gNB-CU) configures a network energy-saving-based CHO measurement event for a terminal device that does not support the cell's Cell DTX / DRX, the base station centralized unit (gNB-CU) informs the base station distributed unit (gNB-DU) whether the cell needs to be deactivated or the cell's Cell DTX / DRX needs to be activated.

[0359] The first F1 application protocol signaling may also be referred to as a GNB-CU CONFIGURATION UPDATE message. Table 2 shows the first case of the first F1 application protocol signaling. Table 3 shows the second case of the first F1 application protocol signaling.

[0360]

[0361]

[0362]

[0363] Table 2 shows the first case of the first F1 application protocol signaling

[0364] As shown in Table 2, a group name (IE / Group Name) named "Deactivated for NES" is added to the first F1 application protocol signaling (GNB-CU CONFIGURATION UPDATE message). "Deactivated for NES" is used to represent the first indication information and indicates that the first indication information is "deactivated cell." The Presence of the first indication information is 0. The type of the request information (IE type and reference) is "ENUMERATED (true, ...)." The semantics description of the first indication information is "Indicates that the concerned cell is deactivated for energy saving reasons." This semantic description indicates that the cell is deactivated.

[0365]

[0366]

[0367]

[0368] Table 3 shows the second case of the first F1 application protocol signaling

[0369] As shown in Table 3, in the first F1 application protocol signaling (GNB-CU CONFIGURATION UPDATE message), a group name (IE / Group Name) is added as "Trigger NES CHO". "Trigger NES CHO" is used to represent the above-mentioned first indication information, and indicates that the first indication information is "instructing the base station distribution unit to send the second control information to the terminal equipment in the cell". Among them, the Presence of the first indication information is 0. The type of the request information (IE type and reference) is "ENUMERATED (true,...)". The semantic description (Semantics description) of the first indication information is "Indicates NES-specific CHO should be triggered in the cells." The semantic description instructs the base station distribution unit to send the second control information to the terminal equipment in the cell.

[0370] Step 803: The base station centralized unit receives the first response information sent by the base station distributed unit; wherein the first response information is used to indicate that the first indication information has been received.

[0371] In this embodiment, after the gNB-DU receives the first F1 application protocol signaling (first F1AG signaling) sent by the gNB-CU, the gNB-DU feeds back a first response message to the gNB-CU to inform the gNB-CU of receipt of the first indication message.

[0372] The first response information may also be referred to as a GNB-CU CONFIGURATION UPDATE ACKNOWLEDGE message.

[0373] Step 804: The base station distribution unit sends second control information to the terminal equipment in the cell; wherein the second control information is used to indicate a CHO measurement event that triggers the terminal equipment based on network energy saving.

[0374] In this embodiment, since the first indication information in the first F1 application protocol signaling is also used to instruct the base station distribution unit (GNB-DU) to send second control information to the terminal device in the cell, after the base station distribution unit (gNB-DU) receives the first F1 application protocol signaling, the base station distribution unit (gNB-DU) sends the second control information to the terminal device in the cell that does not support the cell's CellDTX / DRX; the second control information is used to indicate a network energy-saving-based CHO measurement event that triggers the terminal device; and thereby triggers a network energy-saving-based CHO measurement event for the terminal device that does not support the cell's Cell DTX / DRX.

[0375] The second control information may be carried in the downlink control information. For example, the downlink control information is DCI2-9, that is, the downlink control information is L1 signaling for indicating a CHO measurement event based on network energy saving that triggers the terminal device.

[0376] In this embodiment, the base station centralized unit (gNB-CU) determines that a cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which means deactivating the cell), and then releases the configuration information about the cell for the terminal device in the cell, or switches the terminal device in the cell to another cell; then, the base station centralized unit (gNB-CU) sends first indication information to the base station distributed unit (gNB-DU), and the first indication information is used to instruct the cell to enter an energy-saving state; thereby, the base station centralized unit (gNB-CU) informs the base station distributed unit (gNB-DU) through the first indication information that the cell configuration has been released for the terminal device or the terminal device in the cell has been switched to another cell. Alternatively, the base station centralized unit (gNB-CU) determines that the cell needs to enter the energy-saving state (in this case, the cell needs to enter the energy-saving state, which is to activate the Cell DTX / DRX of the cell), and then sends first control information to the terminal device in the cell that does not support the Cell DTX / DRX of the cell. The first control information is used to configure a CHO measurement event based on network energy saving for the terminal device; thereby, the base station centralized unit (gNB-CU) informs the base station distributed unit (gNB-DU) through the first indication information that a CHO measurement event based on network energy saving has been configured for the terminal device in the cell that does not support the Cell DTX / DRX of the cell; and then the base station distributed unit (gNB-DU) can send signaling for instructing the terminal device in the cell to trigger a CHO measurement event based on network energy saving. Through the above process, when the network equipment determines that a cell needs to enter the energy-saving state, signaling is exchanged between the gNB-CU and the gNB-DU. Both are informed of the cell's energy-saving state, allowing the gNB-DU to ultimately complete the process of achieving network energy saving. This enables the various units of the network equipment to coordinate control of the cell's energy-saving state, thereby achieving the goal of network energy saving.

[0377] Figure 9 A signaling diagram of a method for triggering network energy saving provided in an embodiment of the present application is shown in FIG. Figure 9 As shown, an embodiment of the present application provides a method for triggering network energy saving, which can be applied to the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) of the network device in the aforementioned 5G / 6G system structure, so that when it is determined that a cell needs to enter an energy-saving state, each unit of the network device can obtain the information (that is, the cell needs to enter an energy-saving state) and perform related operations, that is, the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) can obtain the information and perform related operations, so that each unit of the network device controls the cell to enter an energy-saving state, thereby achieving the purpose of collaboratively controlling the cell to enter an energy-saving state. The method provided in this embodiment includes the following steps:

[0378] Step 901: The base station centralized unit determines that the cell needs to enter the energy-saving state, releases the configuration information about the cell of the terminal device in the cell, or sends first control information to the terminal device in the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal device.

[0379] In this embodiment, in a split gNB architecture, the network device includes a base station centralized unit (gNB-CU) and a base station distributed unit (gNB-DU), wherein the gNB-CU and the gNB-DU are independent of each other.

[0380] The gNB-CU determines whether the cell needs to enter the energy-saving state.

[0381] The base station centralized unit (gNB-CU) determines whether a cell needs to enter an energy-saving state in the following two ways.

[0382] The first method: The base station centralized unit (gNB-CU) determines whether the cell needs to enter the energy-saving state.

[0383] The second method: The gNB-DU determines whether a cell should enter the energy-saving state. If so, the gNB-DU sends a request to the gNB-CU, requesting the cell enter the energy-saving state. The gNB-CU then determines that the cell should enter the energy-saving state.

[0384] Then, when the base station centralized unit (gNB-CU) determines that the cell needs to enter the energy-saving state, the following process is performed.

[0385] If the gNB-CU determines that a cell needs to enter an energy-saving state, and the energy-saving state is a deactivated cell (i.e., a cell shutdown), the gNB-CU releases the cell configuration for all terminal devices in the cell or sends a handover command to all terminal devices in the cell. In this case, the gNB-CU releases the cell configuration information for each terminal device in the cell. Specifically, the gNB-CU sends first control information to each terminal device in the cell, thereby configuring a network energy-saving CHO measurement event for each terminal device.

[0386] If the gNB-CU determines that the cell needs to enter an energy-saving state, and the "energy-saving state" is to activate Cell DTX / DRX of the cell, the gNB-CU releases the cell configuration for the terminal devices in the cell that do not support Cell DTX / DRX, or sends a switching command to the terminal devices in the cell that do not support Cell DTX / DRX. At this time, the gNB-CU releases the cell configuration information for each terminal device in the cell; in particular, the gNB-CU sends first control information to the terminal devices in the cell that do not support Cell DTX / DRX (i.e., to the terminal devices in the cell that support network energy saving CHO), thereby configuring a CHO measurement event based on network energy saving for the terminal devices.

[0387] Among them, the terminal device supporting network energy-saving CHO means that the terminal device supports the network energy-saving CHO capability, that is, the terminal device supports the "triggering terminal device measurement event based on network energy-saving CHO" triggered by downlink control information (for example, DCI 2-9).

[0388] Step 902: The base station centralized unit sends a first F1 application protocol signaling to the base station distributed unit. The first F1 application protocol signaling includes first indication information, which is used to instruct the cell to enter an energy-saving state. The first indication information is also used to instruct the base station distributed unit to send second control information to terminal devices in the cell.

[0389] In this embodiment, after the gNB-CU executes step 801, the gNB-CU sends a first F1 application protocol signaling (first F1AG signaling) to the gNB-DU. The first F1 application protocol signaling includes first indication information. The first indication information is used to instruct the cell to enter the energy-saving state.

[0390] If the gNB-CU determines that a cell needs to enter an energy-saving state, and the energy-saving state is a deactivated cell, then after executing step 001, the gNB-CU sends a first F1 application protocol signaling to the gNB-DU. The first F1 application protocol signaling includes first indication information, which includes information indicating cell deactivation (i.e., the first indication information indicates cell deactivation). For example, the first indication information is a deactivate indication (or cell deactivation indication). The gNB-DU then deactivates the cell. This process is not shown in the diagram of this embodiment.

[0391] Alternatively, if the gNB-CU determines that the cell needs to enter an energy-saving state, and the energy-saving state is to activate Cell DTX / DRX for the cell, then after executing step 901, the gNB-CU sends a first F1 application protocol signaling to the gNB-DU. The first F1 application protocol signaling includes first indication information, and the first indication information includes information indicating activation of Cell DTX / DRX for the cell (i.e., the first indication information indicates activation of Cell DTX / DRX for the cell). The gNB-DU then executes step 904 to activate the Cell DTX / DRX function for the cell of the terminal device.

[0392] In which, in the case of the above-mentioned "first indication information indicating activation of Cell DTX / DRX of the cell" in this step, the first F1 application protocol signaling (GNB-CU CONFIGURATION UPDATE message) can be shown in Table 4.

[0393] Table 4 shows the third case of the first F1 application protocol signaling.

[0394]

[0395]

[0396]

[0397] Table 4 shows the third case of the first F1 application protocol signaling

[0398] As shown in Table 4, in the first F1 application protocol signaling (GNB-CU CONFIGURATION UPDATE message), a group name (IE / Group Name) is added as "Cell DTXDRX Activation". "Cell DTXDRXActivation" is used to represent the above-mentioned first indication information, and indicates that the first indication information is "Cell DTX / DRX of the activated cell". Among them, the Presence of the first indication information is 0. The type of request information (IE type and reference) is "ENUMERATED (true, ...)". The semantics description (Semantics description) of the first indication information is "Indicates cell DTX / DRX can be activated for the cells." The semantic description indicates that the Cell DTX / DRX of the activated cell.

[0399] Step 903: The base station centralized unit receives the first response information sent by the base station distributed unit; wherein the first response information is used to indicate that the first indication information has been received.

[0400] In this embodiment, after the gNB-DU receives the first F1 application protocol signaling (first F1AG signaling) sent by the gNB-CU, the gNB-DU feeds back a first response message to the gNB-CU to inform the gNB-CU of receipt of the first indication message.

[0401] Step 904: The base station distribution unit sends third control information to the terminal equipment in the cell, where the third control information is used to instruct the activation of the Cell DTX / DRX function of the cell of the terminal equipment.

[0402] In this embodiment, after receiving the first F1 application protocol signaling, the base station distribution unit (gNB-DU) sends third control information to the terminal device in the cell that supports Cell DTX / DRX of the cell, wherein the third control information is used to indicate activation of the Cell DTX / DRX function of the cell of the terminal device; thereby triggering a CHO measurement event of the terminal device that supports Cell DTX / DRX of the cell.

[0403] The third control information may be carried in downlink control information, such as DCI 2-9, or in RRC signaling.

[0404] For terminal devices that support L1 signaling DCI 2_9 to activate cell DTX / DRX, the base station distribution unit (gNB-DU) sends downlink control information to the terminal device, where the downlink control information includes third control information.

[0405] For the terminal device that activates the cell Cell DTX / DRX by L1 signaling DCI 2_9, the base station distribution unit (gNB-DU) sends RRC signaling to the terminal device, where the RRC signaling includes third control information.

[0406] Step 905: The base station distribution unit sends second control information to the terminal equipment in the cell; wherein the second control information is used to indicate a CHO measurement event that triggers the terminal equipment based on network energy saving.

[0407] In this embodiment, when the first indication information in the first F1 application protocol signaling is used to indicate the deactivation of a cell (i.e., the first indication information carries a cell deactivation indication), or when the first indication information in the first F1 application protocol signaling is used to indicate the activation of the Cell DTX / DRX of the cell (i.e., the first indication information carries a Cell DTX / DRX activation indication), the first indication information is also used to instruct the base station distribution unit (gNB-DU) to send a control instruction for triggering a network energy-saving-based CHO measurement event of the terminal device.

[0408] Therefore, after the base station distribution unit (gNB-DU) receives the first F1 application protocol signaling, the base station distribution unit (gNB-DU) sends second control information to the terminal device in the cell that does not support the cell's Cell DTX / DRX; the second control information is used to indicate the triggering of a network energy-saving CHO measurement event for the terminal device; and thereby triggering a network energy-saving CHO measurement event for the terminal device that does not support the cell's Cell DTX / DRX.

[0409] In this embodiment, the base station centralized unit (gNB-CU) determines that a cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which means deactivating the cell), and then releases the configuration information about the cell for the terminal device in the cell, or switches the terminal device in the cell to another cell; then, the base station centralized unit (gNB-CU) sends first indication information to the base station distributed unit (gNB-DU), and the first indication information is used to instruct the cell to enter an energy-saving state; thereby, the base station centralized unit (gNB-CU) informs the base station distributed unit (gNB-DU) through the first indication information that the cell configuration has been released for the terminal device or the terminal device in the cell has been switched to another cell. Alternatively, the base station central unit (gNB-CU) determines that the cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which is to activate Cell DTX / DRX of the cell), and then sends first control information to the terminal equipment in the cell that does not support Cell DTX / DRX of the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal equipment; thereby, the base station central unit (gNB-CU) notifies the base station distribution unit (gNB-DU) through the first indication information that a CHO measurement event based on network energy saving has been configured for the terminal equipment in the cell that does not support Cell DTX / DRX of the cell; and then the base station distribution unit (gNB-DU) can send signaling for instructing the terminal equipment to trigger a CHO measurement event based on network energy saving, and / or the base station distribution unit (gNB-DU) sends signaling for instructing the terminal equipment to activate the Cell DTX / DRX function of the cell of the terminal equipment to support Cell DTX / DRX of the cell. Through the above process, when the network equipment determines that a cell needs to enter the energy-saving state, signaling is exchanged between the gNB-CU and the gNB-DU. Both are informed of the cell's energy-saving state, allowing the gNB-DU to ultimately complete the process of achieving network energy saving. This enables the various units of the network equipment to coordinate control of the cell's energy-saving state, thereby achieving the goal of network energy saving.

[0410] Figure 10 A signaling diagram of a method for triggering network energy saving provided in an embodiment of the present application is shown in FIG. Figure 10As shown, an embodiment of the present application provides a method for triggering network energy saving, which can be applied to the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) of the network device in the aforementioned 5G / 6G system structure, so that when it is determined that a cell needs to enter an energy-saving state, each unit of the network device can obtain the information (that is, the cell needs to enter an energy-saving state) and perform related operations, that is, the base station centralized unit (gNB-CU) and the base station distributed unit (gNB-DU) can obtain the information and perform related operations, so that each unit of the network device controls the cell to enter an energy-saving state, thereby achieving the purpose of collaboratively controlling the cell to enter an energy-saving state. The method provided in this embodiment includes the following steps:

[0411] Step 1001: The base station centralized unit receives a request message sent by the base station distributed unit; wherein the request message is used to request the cell to enter an energy-saving state.

[0412] In this embodiment, in a split gNB architecture, the network device includes a base station centralized unit (gNB-CU) and a base station distributed unit (gNB-DU), wherein the gNB-CU and the gNB-DU are independent of each other.

[0413] For this embodiment, please refer to the introduction of step 601 and will not be repeated here.

[0414] Step 1002: The base station centralized unit sends a second response message to the base station distributed unit; wherein the second response message is used to indicate receipt of the request message.

[0415] In this embodiment, after the gNB-CU receives the second F1 application protocol signaling (second F1AG signaling) sent by the gNB-DU, the gNB-CU needs to feed back a second response message to the gNB-DU to inform the gNB-DU of receipt of the request message.

[0416] For this embodiment, please refer to the introduction of step 602 and will not be repeated here.

[0417] Step 1003: The base station centralized unit determines that the cell needs to enter an energy-saving state, releases the configuration information about the cell of the terminal device in the cell, or sends first control information to the terminal device in the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal device.

[0418] In this embodiment, please refer to the introduction of step 603 and no further details will be given.

[0419] Step 1004: The base station centralized unit sends a first F1 application protocol signaling to the base station distributed unit. The first F1 application protocol signaling includes first indication information, which is used to instruct the cell to enter an energy-saving state. The first indication information is also used to instruct the base station distributed unit to send second control information to terminal devices in the cell.

[0420] In this embodiment, please refer to the introduction of step 902 and will not be repeated here.

[0421] Step 1005: The base station centralized unit receives first response information sent by the base station distributed unit; wherein the first response information is used to indicate receipt of the first indication information.

[0422] In this embodiment, after the gNB-DU receives the first F1 application protocol signaling (first F1AG signaling) sent by the gNB-CU, the gNB-DU feeds back a first response message to the gNB-CU to inform the gNB-CU of receipt of the first indication message.

[0423] In this embodiment, please refer to the introduction of step 903 and no further details will be given.

[0424] Step 1006: The base station distribution unit sends third control information to the terminal equipment in the cell, where the third control information is used to instruct to activate the Cell DTX / DRX function of the cell of the terminal equipment.

[0425] In this embodiment, please refer to the introduction of step 904 and no further details will be given.

[0426] Step 1007: The base station distribution unit sends second control information to the terminal equipment in the cell; wherein the second control information is used to indicate a CHO measurement event that triggers the terminal equipment based on network energy saving.

[0427] In this embodiment, please refer to the introduction of step 905 and no further details will be given.

[0428] In this embodiment, the base station centralized unit (gNB-CU) determines that a cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which means deactivating the cell), and then releases the configuration information about the cell for the terminal device in the cell, or switches the terminal device in the cell to another cell; then, the base station centralized unit (gNB-CU) sends first indication information to the base station distributed unit (gNB-DU), and the first indication information is used to instruct the cell to enter an energy-saving state; thereby, the base station centralized unit (gNB-CU) informs the base station distributed unit (gNB-DU) through the first indication information that the cell configuration has been released for the terminal device or the terminal device in the cell has been switched to another cell. Alternatively, the base station central unit (gNB-CU) determines that the cell needs to enter an energy-saving state (in this case, the cell needs to enter an energy-saving state, which is to activate Cell DTX / DRX of the cell), and then sends first control information to the terminal equipment in the cell that does not support Cell DTX / DRX of the cell, where the first control information is used to configure a CHO measurement event based on network energy saving for the terminal equipment; thereby, the base station central unit (gNB-CU) notifies the base station distribution unit (gNB-DU) through the first indication information that a CHO measurement event based on network energy saving has been configured for the terminal equipment in the cell that does not support Cell DTX / DRX of the cell; and then the base station distribution unit (gNB-DU) can send signaling for instructing the terminal equipment to trigger a CHO measurement event based on network energy saving, and / or the base station distribution unit (gNB-DU) sends signaling for instructing the terminal equipment to activate the Cell DTX / DRX function of the cell of the terminal equipment to support Cell DTX / DRX of the cell. Through the above process, when the network equipment determines that a cell needs to enter the energy-saving state, signaling is exchanged between the gNB-CU and the gNB-DU. Both are informed of the cell's energy-saving state, allowing the gNB-DU to ultimately complete the process of achieving network energy saving. This enables the various units of the network equipment to coordinate control of the cell's energy-saving state, thereby achieving the goal of network energy saving.
