Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a wireless communication method, apparatus, network equipment and storage medium. Background Art

[0002] At present, in mobile communication networks, carrier aggregation (CA) technology and / or dual connectivity (DC) technology can be used to provide services for the same terminal through multiple cells, so as to improve system capacity and data transmission rate, etc., thereby improving user experience. Among them, when using CA technology and / or DC technology, cells provided by two different network devices can jointly serve the same terminal. Among them, one of the two network devices serves as the main node of the terminal, and the main node provides the terminal with a primary cell (Pcell) or a master cell group (MCG), and the other network device serves as the auxiliary node of the terminal, and the auxiliary node provides the terminal with a secondary cell (Scell) or a secondary cell group (SCG).

[0003] In the related art, when the service volume of a terminal is small, the master node of the terminal can send indication information to the terminal to instruct the terminal to set the Scell ​​or SCG provided by the auxiliary node to a deactivated state, so that the terminal stops sending and receiving information on the cell in the Scell ​​or SCG, thereby saving the power consumption of the terminal and, to a certain extent, the power consumption of the auxiliary node. However, in this method of deactivating the Scell ​​or SCG based on the terminal as the granularity, the energy saving effect of the auxiliary node is relatively limited. Summary of the invention

[0004] The present application provides a wireless communication method, apparatus, network equipment and storage medium, which can improve the energy saving effect of auxiliary nodes.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a wireless communication method is provided, which is applied to a first network device, and the method includes: when the load of the first network device is not greater than a load threshold, switching from a normal state to a power-saving state, and stopping providing services to at least one first terminal; and providing services to a second terminal under the scheduling of a second network device; wherein the secondary cell of the second terminal is a cell provided by the first network device, and the primary cell of the second terminal is a cell provided by the second network device; or, the cells in the secondary cell group SCG of the second terminal are cells provided by the first network device, and the cells in the main cell group MCG of the second terminal are cells provided by the second network device, and the first terminal is different from the second terminal.

[0007] In the present application, when the load of the first network device is less than the load threshold, the first network device can switch from the normal state to the energy-saving state, so as to provide services to the second terminal with the first network device as the auxiliary node, and stop providing services to at least one first terminal that does not use the first network device as the auxiliary node. In this way, the first network device achieves cell-level energy saving while maintaining support for DC and / or CA functions, thereby enhancing the energy-saving effect of the first network device.

[0008] Optionally, the stopping of providing service to at least one first terminal includes: stopping broadcasting remaining minimum system information (RMSI).

[0009] Since RMSI contains the information required for the terminal to make initial access, by stopping broadcasting RMSI, the first terminal to access the first network device within the signal coverage of the first network device cannot obtain the information required for access, and thus cannot access the first network device.

[0010] Optionally, the stopping of providing service to at least one first terminal further includes: stopping sending paging information to the at least one first terminal.

[0011] In the present application, stopping sending paging information to at least one first terminal that is currently in an idle state or an inactive state can further save energy consumption of the network device.

[0012] Optionally, before switching from the normal state to the energy-saving state, it also includes: sending an energy-saving state activation notification to the second network device, the energy-saving state activation notification including first service capability information, the first service capability information being used to indicate the maximum service capability of the first network device in the energy-saving state; providing services to the second terminals under the scheduling of the second network device, including: providing services to N second terminals under the scheduling of the second network device based on the first service capability information, where N is an integer greater than 0.

[0013] In the present application, the first network device can notify the second network device when entering the energy-saving state, and provide the second network device with its maximum service capability in the energy-saving state. On this basis, the second network device can schedule the first network device to undertake the data transmission service of the second terminal within the capability of the first network device, thereby saving the power consumption of the first network device and ensuring the normal operation of the business.

[0014] In addition, by notifying the second network device that the first network device has entered the energy-saving state, the second network device can stop switching the terminals that do not support CA and / or DC and are connected to the second network device to the first network device. That is, after the second network device learns that the first network device has entered the energy-saving state, it can stop interacting with the first network device and the terminals that do not support CA and / or DC regarding terminal switching. In this way, energy consumption of both the second network device and the first network device can be saved.

[0015] Optionally, the first service capability information includes a maximum number of service terminals, and N is not greater than the maximum number of service terminals.

[0016] Optionally, the first service capability information includes a maximum data transmission rate, and a data transmission rate when data is transmitted between the first network device and the N second terminals is not greater than the maximum data transmission rate.

[0017] Optionally, the implementation process of switching from the normal state to the energy-saving state includes: responding to a confirmation message of the energy-saving state start notification from the second network device, switching from the normal state to the energy-saving state.

[0018] Optionally, after switching from the normal state to the energy-saving state, it also includes: receiving a normal state recovery request from the second network device; based on the normal state recovery request, switching from the energy-saving state to the normal state; and sending a confirmation message of the normal state recovery request to the second network device.

[0019] In the present application, the second network device may actively request the first network device to recover from the energy-saving state to the normal state, so that the first network device helps the second network device to share the network pressure.

[0020] Optionally, the normal state recovery request includes load information of the second network device; and switching from the energy-saving state to the normal state based on the normal state recovery request includes: if the load information of the second network device meets the normal state recovery condition, switching from the energy-saving state to the normal state.

[0021] Optionally, after switching from the normal state to the energy-saving state, it also includes: receiving load information of the second network device; if the load information of the second network device meets the normal state recovery condition, sending a normal state start notification to the second network device, and switching from the energy-saving state to the normal state.

[0022] In the present application, the second network device may also feed back load information to the first network device, and the first network device may make a decision based on the load information to actively restore to a normal state.

[0023] Optionally, the load information of the second network device includes the total number of terminals currently served by the second network device, and a first ratio between the number of the second terminals among the currently served terminals and the total number of currently served terminals; the normal state recovery condition includes that the total number of terminals currently served is greater than a first threshold, and the first ratio is less than a second threshold.

[0024] In the present application, if the total number of terminals currently served by the second network device is greater than the first threshold, it means that the load of the second network device is relatively high. On this basis, if the first ratio is less than the second threshold, it means that among the terminals served by the second network device, the proportion of second terminals served by the first network device and the second network device is relatively small. In this case, the first network device can determine that the current network is relatively busy and meets the normal state recovery conditions, so it can recover from the energy-saving state to the normal state and resume the service to the first terminal within its signal coverage range, so as to share the service pressure of the second network device and meet the user's service needs at the same time.

[0025] Optionally, the method also includes: receiving deactivation indication information sent by the second network device, the deactivation indication information is used to indicate deactivation of at least one first cell, the at least one first cell is a secondary cell of at least one second terminal, or the at least one first cell is a cell in the SCG of the at least one second terminal; based on the deactivation indication information, switching the at least one first cell to a deactivated state, wherein, in the deactivated state, the at least one first cell stops providing services to the at least one second terminal.

[0026] In the present application, after the first network device enters the energy-saving state, the second network device can also send a deactivation notification to at least one second terminal served by at least one first cell, and send deactivation indication information to the first network device to instruct the deactivation of the at least one first cell, thereby instructing each second terminal on the at least one first cell to stop transmitting data with the first network device, thereby realizing deactivation of the entire cell on the network device side and enhancing the energy-saving effect of the network device.

[0027] Optionally, after switching the at least one first cell to the deactivated state based on the deactivation indication information, it also includes: if all cells provided by the first network device are in the deactivated state, and the time length for each cell to maintain the deactivated state is greater than a time length threshold, sending a shutdown state start notification to the second network device and switching to the shutdown state, wherein, in the shutdown state, sending and receiving signals are stopped.

[0028] In the present application, if all cells on the first network device are in a deactivated state and have not been activated for a long time, the first network device can be shut down and stop sending and receiving signals, thereby further enhancing the energy-saving effect of the network device.

[0029] Optionally, after the first network device deactivates at least one first cell, the method also includes: receiving activation indication information sent by the second network device, the activation indication information being used to indicate activation of at least one second cell, the at least one first cell including the at least one second cell; based on the activation indication information, switching the at least one second cell to an activated state, wherein in the activated state, the at least one second cell provides service for at least one second terminal.

[0057] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0058] Before explaining the embodiments of the present application in detail, the application scenarios involved in the embodiments of the present application are first introduced.

[0059] With the popularization of mobile terminals, the business demand of mobile communication networks has grown exponentially, while spectrum resources are limited and fixed. Based on this, CA technology can be used to provide services to the same terminal through multiple cells, thereby improving the peak rate of the terminal and improving user experience.

[0060] It should be noted that the multiple cells aggregated by CA technology are cells provided by network devices that adopt the same wireless access technology. The multiple cells may be cells provided by the same network device or cells provided by two network devices. For example, the multiple cells may be different cells provided by two micro base stations under the same macro base station. In this case, one of the two micro base stations may serve as the main node of the terminal and provide Pcell for the terminal, and the other micro base station may serve as the auxiliary node of the terminal and provide Scell ​​for the terminal. The Scell ​​of the terminal can not only provide services for the terminal, but also serve other terminals located in the cell. For example, it can serve other terminals that use the Scell ​​as the main cell or other terminals that do not support CA technology and use the Scell ​​as the service cell.

[0061] In addition, DC technology is proposed in the fifth generation (5th generation, 5G) new radio (new radio, NR) technology. The so-called DC means that the terminal can be connected to two network devices at the same time, and the cells provided by the two network devices provide services for the terminal. Among them, the two network devices can be network devices using the same radio access technology, or they can be network devices using different radio access technologies. Among them, one network device can serve as the main node of the terminal and provide Pcell for the terminal, and the other network device can serve as the auxiliary node of the terminal and provide Scell ​​for the terminal. Alternatively, the main node can use CA technology to provide MCG for the terminal, and the MCG may include multiple cells, including one Pcell and at least one Scell. The auxiliary node can use CA technology to provide SCG for the terminal, wherein SCG may also include multiple cells, including one primary secondary cell (PScell) and at least one Scell. Among them, the auxiliary node can provide data transmission services for the terminal in the cell in the SCG. In addition, the auxiliary node can also provide services for other terminals located in the cell in the SCG. For example, it can provide services for other terminals that do not support DC technology and are located in the cell in the SCG.

[0062] In the CA scenario and / or DC scenario described above, when the traffic volume of the terminal is small, the master node of the terminal can send an indication message to the terminal to instruct the terminal to set the Scell ​​or SCG provided by the auxiliary node to a deactivated state, so that the terminal stops sending and receiving information on the cell in the Scell ​​or SCG, thereby saving the power consumption of the terminal. Correspondingly, the auxiliary node of the terminal may no longer transmit data with the terminal in the cell in the Scell ​​or SCG, thereby saving energy consumption. However, although the auxiliary node no longer transmits data with the terminal in the cell in the Scell ​​or SCG, the auxiliary node may still transmit data with other terminals in the cell in the Scell ​​or SCG to serve other terminals, for example, terminals that also use the Scell ​​or SCG as their own Scell ​​or SCG, or other terminals that do not support CA or DC technology and are located in the cell in the Scell ​​or SCG. In this case, the energy consumption that can be saved by the auxiliary node is very limited. Based on this, an embodiment of the present application provides a wireless communication method that can be applied to the above-mentioned CA and / or DC scenarios. In this method, when the load of the first network device serving as an auxiliary node of the second terminal is less than a load threshold, the first network device can switch from a normal state to an energy-saving state, so as to provide services to the second terminal with the first network device as an auxiliary node, and stop providing services to the first terminal that does not have the first network device as an auxiliary node. In this way, the first network device achieves cell-level energy saving while maintaining support for DC and / or CA functions, thereby enhancing the energy saving effect of the first network device.

[0063] Next, the structure of the wireless communication system involved in the wireless communication method provided in the embodiment of the present application is introduced.

[0064] The wireless communication method provided in the embodiment of the present application can be applied to various communication systems, such as 5G NR communication system, long term evolution (LTE) network, enhanced long term evolution (eLTE) network, universal mobile telecommunications system (UMTS) system, code division multiple access (CDMA) system, etc., and can also be a sixth generation (6G) communication system or other future-oriented communication systems. In addition, the wireless communication method provided in the embodiment of the present application can also be used in terrestrial networks (TN) and / or non-terrestrial networks (NTN), without limitation.

[0065] Figure 1 Schematic diagram of a wireless communication system provided in an embodiment of the present application. Figure 1 As shown, the wireless communication system includes a first network device 101, a second network device 102 and a terminal 103, wherein the terminal 103 can be connected to the first network device 101 and the second network device 102 at the same time.

[0066] In a possible implementation, the terminal 103 uses the DC technology to simultaneously transmit data with the first network device 101 and the second network device 102. The second network device 102 is the primary node of the terminal 103, and the first network device 101 is the secondary node of the terminal 103. Figure 2 The second network device 102 may provide an MCG for the terminal 103, and the first network device 101 may provide an SCG for the terminal 103. The MCG may include a Pcell and at least one Scell, and the SCG may include a PScell ​​and at least one Scell.

[0067] It should be noted that the first network device 101 and the second network device 102 may be network devices using different wireless access technologies. For example, the first network device 101 may be a base station in the fourth generation (4G), for example, an evolved node B (eNB), and the second network device 102 may be a base station in 5G, wherein the base station in 5G may also be referred to as a transmission reception point (TRP) or a next generation base station (next generation node B, gNB). Alternatively, the first network device 101 may be a base station in 5G, and the second network device may be a base station in 4G. Of course, the first network device 101 and the second network device 102 may also be network devices using the same wireless access technology, for example, the first network device 101 and the second network device 102 are both base stations in 5G.

[0068] In addition, in this implementation, the first network device 101 and the second network device 102 may be macro base stations, micro base stations or indoor stations. For example, the second network device 102 may be a macro base station, and the first network device 101 may be a micro base station.

[0069] In another possible implementation, the terminal 103 uses the CA technology to simultaneously transmit data with the first network device 101 and the second network device 102. Figure 3, a certain cell provided by the second network device 102 can be used as a Pcell of the terminal 103 , and at least one cell provided by the first network device 101 can be used as a Scell ​​of the terminal 103 .

[0070] It should be noted that the first network device 101 and the second network device 102 are network devices that use the same wireless access technology. For example, the first network device 101 and the second network device 102 can both be base stations that use the evolved universal terrestrial radio access (E-UTRA) technology. In addition, the signal coverage ranges of the first network device 101 and the second network device 102 overlap. For example, the first network device 101 and the second network device 102 can be two micro base stations under the same macro base station, or one of the second network device 102 and the first network device 101 is a macro base station, and the other is a micro base station under the macro base station.

[0071] In the embodiment of the present application, the function of the network device can be performed by a module (such as a chip) in the network device, or by a control subsystem including the base station network device function. The embodiment of the present application does not limit the specific technology and specific device form adopted by the network device.

[0072] In addition, in an embodiment of the present application, the terminal 103 is a terminal supporting DC and / or CA, and the number of the terminal 103 can be one or more. Among them, the terminal 103 is located within the signal coverage of multiple cells provided by the first network device 101 and the second network device 102. The terminal 103 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted, and can also be deployed on the water surface (such as ships, etc.), and can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal can also be called terminal equipment, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device with wireless transceiver function and provides voice and / or data connectivity to users. Exemplarily, the terminal can be a handheld device, vehicle-mounted device, wearable device or computing device with wireless communication function, such as a mobile phone, tablet computer, laptop computer, PDA, mobile internet device (MID), smart bracelet, smart glasses, etc. The terminal may also be a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like. In an embodiment of the present application, a device for realizing the function of a terminal may be referred to as a terminal. Alternatively, a device capable of supporting the terminal to realize the function may be installed in the terminal, for example, the device may be a chip system. Among them, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0082] Next, the wireless communication method provided in the embodiment of the present application is explained in detail.

[0083] Figure 5 is a flow chart of a wireless communication method provided in an embodiment of the present application. The method can be applied to the wireless communication system introduced above, see Figure 5, the method comprises the following steps:

[0084] Step 501: When the load of a first network device is not greater than a load threshold, the first network device switches from a normal state to an energy-saving state to stop providing services to at least one first terminal.

[0085] In an embodiment of the present application, the load of the first network device may include the number of terminals that have accessed the network through the first network device, and the corresponding load threshold may be a pre-set access terminal number threshold. If the number of terminals that have accessed the network through the first network device is not greater than the access terminal number threshold, the first network device may switch from a normal state to an energy-saving state to stop providing services to at least one first terminal. The access terminal number threshold may be 0 or other values.

[0086] The first terminal may refer to a terminal that is located within the signal coverage of the first network device and is to be connected. The first terminal may be a terminal that does not support DC and CA, or a terminal that supports DC and / or CA.

[0087] In addition, the terminal that has accessed the network through the first network device may include a terminal in a cell provided by the Pcell or MCG for the first network device, or a terminal that does not support CA and DC and whose serving cell is a cell provided by the first network device.

[0088] If the number of terminals that have accessed the network through the first network device is not greater than the threshold value of the number of access terminals, it means that there are relatively few terminals that currently rely mainly on the first network device to provide services. Therefore, it can be considered that the load of the first network device is low. In this case, the first network device can switch from the normal state to the energy-saving state, thereby stopping providing services to the first terminal.

[0089] It should be noted that, in the embodiment of the present application, the normal state refers to the state in which the first network device provides normal services to each terminal within the coverage range of its own signal. The energy-saving state refers to the state in which the first network device does not provide services to the first terminal and provides services to the second terminal. Based on this, the first network device switching from the normal state to the energy-saving state may refer to the first network device switching from providing services to each terminal within the coverage range of its own signal to not providing services to the first terminal but providing services to the second terminal.

[0090] The first network device may stop broadcasting the RMSI, thereby stopping providing services to the at least one first terminal, so as to save energy of the first network device.

[0091] It should be noted that the first network device stops broadcasting RMSI, but continues to broadcast synchronization signals including information such as radio frame timing and system frame number. For example, the first network device may continue to broadcast MIB, or may broadcast a defined new signal including synchronization signals and information such as radio frame timing and system frame number, etc., without specific limitation. However, it can satisfy the functions of the terminal measuring signals and performing frame synchronization.

[0092] RMSI includes decoding system information block 1 (SIB1), which may include information required for terminal access and scheduling information of other system information (OSI). Therefore, after stopping broadcasting RMSI, the first terminal to be accessed within the signal coverage of the first network device can obtain the synchronization signal such as MIB sent by the first network device, but cannot obtain the information required for access, so the first terminal to be accessed will not be able to access the first network device, so the first network device can stop providing services to the first terminal to be accessed.

[0093] Optionally, the first network device may also stop sending paging information to the first terminal that has previously accessed the first network device and is currently in an idle state or an inactive state and is waiting to access the first network device, so as to further save energy consumption.

[0094] Optionally, since the first network device stops broadcasting RMSI in the energy-saving state, and RMSI includes OSI scheduling information, when broadcasting RMSI is stopped, the first network device may also stop sending OSI to at least one first terminal in the energy-saving state.

[0095] Step 502: The first network device provides services to the second terminal under the scheduling of the second network device.

[0096] After entering the energy-saving state, the first network device stops providing services to the first terminal, and can also provide services to the second terminal under the scheduling of the second network device.

[0097] Among them, the second terminal refers to a terminal with the first network device as the auxiliary node and the second network device as the main node. If the second terminal is a terminal that supports CA or supports DC but not CA, the Scell ​​of the second terminal is the cell provided by the first network device, and the Pcell is the cell provided by the second network device. If the second terminal is a terminal that supports DC and CA, the cell in the SCG of the second terminal is the cell provided by the first network device, and the cell in the MCG of the second terminal is the cell provided by the second network device. In this case, the second terminal can access the network through the second network device, and the first network device can provide data transmission services for the second terminal under the scheduling of the second network device.

[0098] For the second terminal, if the second terminal is a terminal that supports DC, the second terminal does not need to monitor the RMSI and OSI of the cell in the Scell ​​or SCG. By monitoring the synchronization signal such as MIB of the cell in the Scell ​​or SCG to obtain the wireless frame timing and SFN of the corresponding cell, data can be transmitted on the cell in the Scell ​​or SCG. If the second terminal is a terminal that supports CA but does not support DC, the second terminal can obtain the system information of the Scell ​​through the dedicated radio resource control (RRC) signaling sent by the Pcell of the second terminal, so as to transmit data on the Scell. Based on this, in an embodiment of the present application, the first network device can continue to broadcast the synchronization signal when not broadcasting the RMSI in the energy-saving state. In this way, the wireless frame timing and SFN of the cell or Scell ​​in the SCG can continue to be provided to the second terminal, thereby continuing to provide data transmission services to the second terminal. Furthermore, for the terminals that have not set the cell provided by the first network device as a secondary cell and support CA and / or DC, these terminals can measure the signal strength of the cell provided by the first network device through the synchronization signal broadcast by the first network device, and report the signal strength to the master node that provides the primary cell for these terminals, for example, to the second network device. In this way, the master node can decide whether to set the cell provided by the first network device as the secondary cell of these terminals based on the signal strength reported by these terminals.

[0099] The first network device may receive a scheduling instruction from the second network device, and transmit data to one or more second terminals according to the scheduling instruction. The scheduling instruction may be used to indicate which second terminals' data transmissions the first network device carries, and optionally, may also be used to indicate the amount of data, data transmission rate, etc. transmitted by the first network device to the one or more second terminals.

[0100] In an embodiment of the present application, when the load on the first network device is small, the first network device can switch from a normal state to an energy-saving state to provide services to a second terminal with the first network device as a secondary node, and stop providing services to at least one first terminal that does not have the first network device as a secondary node. In this way, the first network device achieves cell-level energy saving while maintaining support for DC and / or CA functions, thereby enhancing the energy saving effect of the first network device.

[0101] In the above embodiment, when the first network device detects that its own load is small, it can directly enter the energy-saving state to stop providing services to the first terminal, and continue to provide services to the second terminal under the scheduling of the second network device. In some possible implementations, the first network device can also notify the second network device before entering the energy-saving state, and notify the second network device of its maximum service capacity in the energy-saving state, so that the second network device can schedule the first network device to serve the second terminal without exceeding the maximum service capacity of the first network device in the energy-saving state. Based on this, the embodiment of the present application provides another implementation process of the wireless communication method, see Figure 6 , including the following steps:

[0102] Step 601: When the load is less than the load threshold, the first network device sends an energy-saving state activation notification to the second network device, where the energy-saving state activation notification includes first service capability information, and the first service capability information is used to indicate the maximum service capability of the first network device in the energy-saving state. Correspondingly, the second network device receives the energy-saving state activation notification.

[0103] In an embodiment of the present application, when the first network device detects that its load is less than a load threshold, it may send an energy-saving state start notification to the second network device. The energy-saving state start notification is used to notify the second network device that the first network device is about to enter the energy-saving state, and the energy-saving state start notification may carry first service capability information for indicating the maximum service capability of the first network device in the energy-saving state. The maximum service capability of the first network device in the energy-saving state is not higher than the maximum service capability in the normal state.

[0104] Exemplarily, the first service capability information may include at least one of a maximum number of service terminals and a maximum data transmission rate.

[0105] As can be seen from the introduction in the aforementioned embodiments, the first network device will provide services for the second terminal with the first network device as an auxiliary node in the energy-saving state, and will no longer provide services for at least one first terminal that does not use the first network device as an auxiliary node. Based on this, in the embodiments of the present application, the maximum number of service terminals may refer to the maximum number of terminals with the first network device as an auxiliary node that the first network device can serve in the energy-saving state. That is, the maximum number of service terminals is the maximum number of second terminals that the first network device can serve. The maximum data transmission rate may refer to the maximum transmission rate allowed to be achieved by the first network device when transmitting data with the second terminal.

[0106] In addition, in the embodiment of the present application, the implementation method of the first network device detecting whether its own load is less than the load threshold can refer to the relevant introduction in step 501 in the aforementioned embodiment, and the embodiment of the present application will not be repeated here.

[0107] Step 602: The second network device sends a confirmation message of the energy-saving state activation notification to the first network device.

[0108] After receiving the energy-saving state activation notification sent by the first network device, the second network device obtains the first service capability information carried in the energy-saving state activation notification. Thereafter, the second network device may send a confirmation message for the energy-saving state activation notification to the first network device, thereby notifying the first network device that it has received the energy-saving state activation notification and obtained the corresponding service capability information.

[0109] It should be noted that in the embodiment of the present application, this step is an optional step, that is, after receiving the energy-saving state activation notification, the second network device may not send the confirmation message, but directly execute step 604.

[0110] Step 603: The first network device switches from the normal state to the energy-saving state, and stops providing services to at least one first terminal.

[0111] If the second network device executes the above step 602, the first network device can switch from the normal state to the energy-saving state after receiving the confirmation message for the energy-saving state activation notification sent by the second network device, thereby stopping providing services to at least one first terminal. If the second network device does not execute the above step 602, the first network device can switch from the normal state to the energy-saving state while sending the energy-saving state activation notification or after sending it. Alternatively, the first network device can also execute step 603 first, and then send the energy-saving state activation notification to the second network device.

[0112] Among them, the implementation process of the first network device switching from the normal state to the energy-saving state and stopping providing services to at least one first terminal can refer to the relevant introduction in step 501 in the aforementioned embodiment, and the embodiment of the present application will not be repeated here.

[0113] Step 604: The second network device schedules the first network device to provide services to the N second terminals based on the first service capability information.

[0114] After learning that the first network device has entered the energy-saving state and obtaining the first service capability information, the second network device can schedule the first network device to perform data transmission with the N second terminals according to the first service capability information, where N is an integer greater than 0.

[0115] Among them, after the second network device obtains the first service capability information, if there is currently a second terminal that has been connected to the second network device and uses the first network device as an auxiliary node, the second network device can schedule the first network device to transmit data with N second terminals among these second terminals based on the first service capability information. Optionally, if there is currently no second terminal that has been connected and uses the first network device as an auxiliary node, the second network device may temporarily not perform the scheduling operation. Subsequently, when the second network device accesses a terminal that supports CA and / or DC, the second network device may set the cell provided by the first network device as the Scell ​​or SCG of the terminal. At this time, the terminal is the second terminal with the first network device as an auxiliary node. Afterwards, the second network device can schedule the first network device to transmit data with the second terminal based on the first service capability information.

[0116] When the first service capability information includes the maximum number of service terminals, the second network device may determine the above N according to the maximum number of service terminals, wherein N is not greater than the maximum number of service terminals. Afterwards, the second network device may send a scheduling instruction to the first network device and the N second terminals to instruct the first network device and the N second terminals to perform service data transmission on the corresponding Scell ​​or SCG cell.

[0117] Optionally, when the first service capability information includes a maximum data transmission rate, the second network device may schedule the first network device to transmit data with N second terminals based on the maximum data transmission rate, wherein the data transmission rate when the first network device transmits data with the N second terminals is not greater than the maximum data transmission rate.

[0118] Exemplarily, in one possible implementation, the second network device can determine N based on the total number of second terminals, the amount of service data of each second terminal, and the maximum data transmission rate, and send a scheduling instruction to the first network device and the N second terminals to instruct the first network device and the N second terminals to perform service data transmission on the corresponding Scell ​​or SCG cell.

[0119] Alternatively, N is equal to the total number of second terminals, and the second network device can schedule the second network device to undertake the transmission of part of the service data of each second terminal according to the service data volume of each second terminal and the maximum data transmission rate.

[0120] Optionally, when the first service capability information includes the maximum number of service terminals and the maximum data transmission rate, the second network device can schedule the first network device to transmit data with N second terminals based on the maximum number of service terminals and the maximum data transmission rate, wherein N is not greater than the maximum number of service terminals, and the data transmission rate when the first network device transmits data with the N second terminals is not greater than the maximum data transmission rate.

[0121] Optionally, in some possible implementations of the embodiments of the present application, the energy-saving state activation notification sent by the first network device to the second network device may not carry the first service capability information. In this way, after receiving the energy-saving state activation notification sent by the first network device, the second network device can continue to schedule the first network device to transmit data in the energy-saving state according to the scheduling strategy when the first network device is in the normal state.

[0122] In addition, in the embodiment of the present application, after receiving the energy-saving state activation notification from the first network device, the second network device may stop switching the terminal that does not support CA and / or DC connected to the second network device to the first network device. That is, the second network device may stop performing signaling interaction with the first network device and the terminal that does not support CA and / or DC regarding terminal switching, so that the energy consumption of the second network device and the first network device can be saved at the same time.

[0123] In an embodiment of the present application, the first network device can notify the second network device when entering the energy-saving state, and provide the second network device with its maximum service capability in the energy-saving state. On this basis, the second network device can schedule the first network device to undertake the data transmission service of the second terminal within the capability of the first network device, thereby saving the power consumption of the first network device and ensuring the normal operation of the business.

[0124] By the above Figure 6 It can be seen from the embodiment shown that after the second network device learns that the first network device has entered the energy-saving state, it can schedule the first network device to provide data transmission services for the second terminal based on the first service capability information. In this case, if the load of the second network device is large later, the second network device can also actively request the first network device to restore to the normal state, thereby sharing the service pressure for the second network device. For example, see Figure 7 , the process may include the following steps:

[0125] Step 701: The second network device sends a normal state recovery request to the first network device.

[0126] In an embodiment of the present application, when the second network device detects that its own load is large, it can send a normal state recovery request to the first network device to request the first network device to switch from the energy-saving state to the normal state.

[0127] The second network device may send a normal state recovery request to the first network device when detecting that the total number of terminals currently served is greater than a threshold value of the number of service terminals. The terminals currently served by the second network device may include terminals in a cell provided by the Pcell or MCG for the second network device, terminals in a cell that does not support CA and DC and whose serving cell is provided by the second network device, and terminals in a cell provided by the Scell ​​or SCG for the second network device.

[0128] Optionally, the normal state recovery request may carry load information of the second network device. The load information may include the total number of terminals currently served by the second network device. Optionally, in addition to this, the load information may also include a first ratio between the number of second terminals in the currently served terminals and the total number of currently served terminals.

[0129] Step 702: The first network device switches from the energy-saving state to the normal state based on the normal state recovery request.

[0130] After receiving the normal state recovery request, the first network device can switch from the energy-saving state to the normal state, that is, restart to provide normal services to each terminal within the coverage of its own signal. Exemplarily, the first network device can continue to send system information including MIB, RMSI and OSI according to the system information sending mechanism. In addition, the first network device can send paging information, etc. to at least one first terminal within the coverage of its own signal.

[0131] Optionally, if the normal state recovery request also carries the load information of the second network device, the first network device may also decide whether to switch from the energy-saving state to the normal state based on the load information of the second network device.

[0132] Exemplarily, the first network device can determine whether the load information of the second network device meets the normal state recovery condition, and if the load information of the second network device meets the normal state recovery condition, switch from the energy-saving state to the normal state. If the load information of the second network device does not meet the normal state recovery condition, the first network device can maintain the energy-saving state.

[0133] Among them, if the load information of the second network device includes the total number of terminals currently served and the first ratio between the number of second terminals in the currently served terminals and the total number of terminals currently served, the first network device can determine whether the total number of terminals currently served is greater than the first threshold and whether the first ratio is less than the second threshold. If the total number of terminals currently served is greater than the first threshold and the first ratio is less than the second threshold, it is determined that the load information of the second network device meets the normal state recovery condition. If the total number of terminals currently served is not greater than the first threshold or the first ratio is not less than the second threshold, it is determined that the load information of the second network device does not meet the normal state recovery condition.

[0134] It should be noted that if the total number of terminals currently served by the second network device is greater than the first threshold, it means that the load of the second network device is relatively high. On this basis, if the first ratio is less than the second threshold, it means that among the terminals served by the second network device, the proportion of second terminals served by the first network device and the second network device is relatively small. In this case, the first network device can determine that the current network is relatively busy and meets the normal state recovery conditions, so it can recover from the energy-saving state to the normal state and resume the service to the first terminal within its signal coverage range, so as to share the service pressure of the second network device and meet the service needs of users at the same time.

[0135] On the contrary, if the total number of terminals currently served by the second network device is not greater than the first threshold, it means that the load of the second network device is not high, or, if the first ratio is not less than the second threshold, it means that among the terminals currently served by the second network device, the proportion of second terminals served by the first network device and the second network device is relatively large, that is, the first network device has helped the second network device share more service pressure, and the service pressure borne by the second network device alone is relatively small. In this case, the first network device can determine that the current network has not reached the busy level and does not meet the normal state recovery conditions, and therefore, the energy-saving state can be maintained.

[0136] Optionally, if the load information of the second network device includes the total number of terminals currently served but does not include the first ratio, the first network device can determine whether the total number of terminals currently served is greater than the first threshold. If it is greater than the first threshold, it can be determined that the normal state recovery condition is met, thereby switching from the energy-saving state to the normal state.

[0137] Step 703: The first network device sends a confirmation message of the normal state recovery request to the second network device.

[0138] After the first network device is restored to the normal state, it may return a confirmation message for the normal state restoration request to the second network device, thereby notifying the second network device that it has been restored to the normal state.

[0139] Step 704: The second network device schedules the first network device to provide services for the M second terminals based on the second service capability information, where the second service capability information is used to indicate the maximum service capability of the first network device in a normal state.

[0140] After receiving the confirmation message of the normal state recovery request, the second network device may reschedule the first network device to provide services for the M second terminals based on the second service capability information.

[0141] The second service capability information may be used to indicate the maximum service capability of the first network device in a normal state. When the maximum service capability of the first network device in a normal state is the same as the maximum service capability in an energy-saving state, the second service capability information is the same as the first service capability information. When the maximum service capability of the first network device in a normal state is higher than the maximum service capability in an energy-saving state, the second service capability information is different from the first service capability information.

[0142] In addition, the implementation method of the second network device scheduling the first network device to provide services for M second terminals based on the second service capability information can refer to the implementation method of the second network device scheduling the first network device to provide services for N second terminals based on the first service capability information introduced above, and the embodiments of the present application will not be repeated here.

[0143] It should be noted that when the first network device is scheduled to provide services to M second terminals based on the second service capability information, M may be greater than N, or the data transmission rate when the first network device transmits data with the M second terminals may be greater than the data transmission rate when the first network device transmits data with the N second terminals.

[0144] Of course, for other terminals other than the second terminal currently served by the second network device, if there are terminals within the signal coverage of the first network device among these terminals, after the first network device returns to normal state, since the first network device has restored the function of providing normal services to all terminals within its signal coverage, these terminals can also reselect to the cell of the first network device for access, so that the service pressure of the second network device can be reduced. On this basis, when the second network device schedules the first network device to transmit data with M first terminals based on the second service capability information, M may not be greater than N, or the data transmission rate when the first network device transmits data with M second terminals may not be greater than the data transmission rate when the first network device transmits data with N second terminals. Alternatively, in some possible situations, the second network device may not perform step 704, that is, the second network device may not change the scheduling in the energy-saving state, that is, not re-scheduling, so that the first network device can continue to transmit data with N second terminals.

[0145] In the embodiment of the present application, when the second network device itself is under a heavy load, it can actively request the first network device to return to a normal state, thereby sharing the service pressure for the second network device and meeting the service needs of users.

[0146] The above embodiment mainly introduces the implementation process of the second network device actively requesting the first network device to restore to a normal state to share the service pressure. In some possible implementations, the second network device may also send load information to the first network device, and the first network device actively restores to a normal state when the load information of the second network device meets the normal state restoration request. For example, see Figure 8 , the implementation may include the following steps:

[0147] Step 801: The second network device sends load information to the first network device.

[0148] In an embodiment of the present application, the second network device may start from receiving the energy-saving mode activation notification sent by the first network device, and send its own load information to the first network device once at every preset time interval. The load information may include the total number of terminals currently served by the second network device. Optionally, in addition to this, the load information may also include a first ratio between the number of second terminals in the currently served terminals and the total number of currently served terminals.

[0149] Step 802: If the load information of the second network device meets the normal state recovery condition, the first network device switches from the energy-saving state to the normal state.

[0150] Whenever the first network device receives load information sent by the second network device, it can determine whether the load information meets the normal state recovery condition. The implementation method of the first network device determining whether the load information of the second network device meets the normal state recovery condition can refer to the relevant implementation method in the aforementioned step 702, and the embodiments of the present application will not be repeated here.

[0151] After determining that the load information of the second network device meets the normal state recovery condition, the first network device can switch from the energy-saving state to the normal state. The relevant implementation method of the first network device switching from the energy-saving state to the normal state refers to the introduction of step 702 in the above embodiment, and the embodiment of this application will not be repeated here.

[0152] Step 803: The first network device sends a normal state start notification to the second network device.

[0153] After switching from the energy-saving state to the normal state, the first network device may send a normal state start notification to the second network device to notify the second network device that the first network device has been restored to the normal state.

[0154] Optionally, this step may also be performed simultaneously with step 802 .

[0155] Step 804: The second network device schedules the first network device to provide services for the M second terminals based on the second service capability information, where the second service capability information is used to indicate the maximum service capability of the first network device in a normal state.

[0156] The implementation method of this step can refer to the implementation method of the aforementioned step 704, which will not be repeated here.

[0157] In an embodiment of the present application, after the first network device enters the energy-saving state, the second network device can feedback load information to the first network device. After detecting that the load information meets the normal state recovery conditions, the first network device can actively recover to the normal state to help share the service pressure of the second network device and meet the user's service needs.

[0158] By the aforementioned Figure 5 and Figure 6 The method described above shows that, when the first network device is in the energy-saving state, it stops serving at least one first terminal and continues to serve the second terminal with it as the auxiliary node. On this basis, the first network device can also perform the following steps in the energy-saving state: Fig. 9 The method shown deactivates at least one first cell that provides services to the second terminal, thereby further enhancing the energy saving effect of the first network device.

[0159] Step 901: A second network device sends a deactivation notification to at least one second terminal, where the deactivation notification includes an identifier of at least one first cell.

[0160] In the embodiment of the present application, the at least one first cell is a cell in an Scell ​​or SCG of at least one second terminal provided by the first network device.

[0161] When the second network device detects that the service data volume of the second terminal served by any Scell ​​or cell in the SCG provided by the first network device is small, for example, less than the third threshold, the second network device can use the cell in the Scell ​​or SCG as the first cell, and send a deactivation notification to at least one second terminal served by the first cell to notify the at least one second terminal to stop sending and receiving information on the first cell. The third threshold is not greater than the maximum data volume that can be carried by the Pcell or MCG provided by the second network device to serve the second terminal.

[0162] It should be noted that the deactivation notification includes the identifier of at least one first cell determined by the second network device. Optionally, the deactivation notification may also include the identifier of at least one second terminal served by the at least one first cell.

[0163] In addition, in an embodiment of the present application, the deactivation notification can be implemented through any one of an RRC message, a medium access control control element (MAC-CE), and downlink control information (DCI).

[0164] Step 902: The second network device sends deactivation indication information to the first network device, where the deactivation indication information is used to instruct deactivation of at least one first cell.

[0165] After determining the at least one first cell, the second network device may further send deactivation indication information to the first network device to instruct the first network device to deactivate the at least one first cell, wherein the deactivation indication information may include an identifier of the at least one first cell.

[0166] It should be noted that, in the embodiment of the present application, the execution order of the second network device sending a deactivation notification to at least one second terminal and sending a deactivation indication message to the first network device can be arbitrary, that is, the deactivation notification can be sent first, and then the deactivation indication message can be sent, or both can be sent at the same time, or the deactivation indication message can be sent first, and then the deactivation notification can be sent.

[0167] Step 903: The second terminal stops sending and receiving signals on at least one first cell based on the deactivation notification.

[0168] Taking any second terminal among the at least one second terminal as an example, after receiving the deactivation notification, the second terminal can determine the target cell that is its own Scell ​​or a cell in the SCG from the at least one first cell according to the identifier of the at least one first cell carried by the deactivation notification. Afterwards, the second terminal can stop sending and receiving signals on the target cell.

[0169] The second terminal stopping sending and receiving signals on the target cell may include the second terminal stopping sending uplink signals on the target cell and stopping monitoring downlink signals on the target cell.

[0170] Optionally, if the deactivation notification also carries the identifier of at least one second terminal, after determining the target cell, the second terminal can also search whether its own identifier is included in the identifier of at least one second terminal carried in the deactivation notification. If its own identifier is included, the second terminal stops sending and receiving signals on the target cell.

[0171] Step 904: The first network device switches at least one first cell to a deactivated state based on the deactivation indication information to stop providing services for at least one second terminal.

[0172] After receiving the deactivation indication information, the first network device may switch the at least one first cell to a deactivated state based on the identifier of the at least one first cell carried in the deactivation indication information, wherein in the deactivated state, the at least one first cell stops providing services for the at least one second terminal. That is, the at least one first cell is switched to a deactivated state, so as to stop data transmission with the at least one second terminal on the at least one first cell.

[0173] The first network device stops transmitting data with the at least one second terminal on the at least one first cell, including: the first network device stops sending data to the second terminal on the at least one first cell, and stops receiving data sent by the second terminal on the at least one first cell.

[0174] Optionally, the first network device stops transmitting data with the at least one second terminal on the at least one first cell, but the first network device may continue to broadcast a synchronization signal on the at least one first cell. For example, the first network device may continue to broadcast the MIB on the at least one first cell.

[0175] After switching at least one first cell to a deactivated state, the first network device may send a confirmation message for the deactivation indication information to the second network device, so as to notify the second network device that the at least one first cell has been successfully switched to a deactivated state. In this way, the second network device may subsequently stop scheduling the first network device to transmit data on the at least one first cell.

[0176] It should be noted that in the embodiment of the present application, it is possible to execute step 903 first and then step 904, or it is possible to execute step 904 first and then step 903, or both may be executed at the same time, and the embodiment of the present application is not limited to this.

[0177] Optionally, after the first network device switches at least one first cell to a deactivated state based on the deactivation indication information, if all cells provided by the first network device, including the at least one first cell, are in a deactivated state, and the time length for which each cell remains in the deactivated state is greater than a time length threshold, a shutdown state start notification is sent to the second network device, and the device switches to the shutdown state, and stops sending and receiving signals and broadcasting signals.

[0178] That is, if all cells on the first network device are in a deactivated state and have not been activated for a long time, the first network device may be shut down and stop sending or receiving any signal.

[0179] Correspondingly, after receiving the shutdown state start notification from the first network device, the second network device stops scheduling the first network device to perform data transmission.

[0180] In an embodiment of the present application, the second network device can send a deactivation notification to at least one second terminal served by at least one first cell, and send deactivation indication information to the first network device to instruct the deactivation of the at least one first cell, thereby instructing each second terminal on the at least one first cell to stop transmitting data with the first network device, thereby realizing deactivation of the entire cell on the network device side and enhancing the energy-saving effect of the network device.

[0181] In addition, if all cells on the first network device are in a deactivated state and have not been activated for a long time, the first network device can be shut down and stop sending and receiving signals, thereby further enhancing the energy saving effect of the network device.

[0182] In an embodiment of the present application, the second network device may instruct the first network device and at least one second terminal to deactivate at least one first cell by the method described in the above embodiment. Correspondingly, the second network device may also instruct the first network device and at least one second terminal to activate at least one second cell. Among them, at least one first cell includes the at least one second cell. That is, the second network device may instruct the first network device and at least one second terminal to activate one or more cells in the first cell that is in a deactivated state. For example, please continue to refer to Fig. 9 , the process may include the following steps:

[0183] Step 905: The second network device sends activation indication information to the first network device, where the activation indication information is used to indicate activation of at least one second cell.

[0184] The activation indication information may include an identifier of at least one second cell. The at least one second cell may be one or more cells in the aforementioned first cell.

[0185] In an embodiment of the present application, when the second network device detects that the amount of business data of terminals supporting CA and / or DC connected to it exceeds a preset threshold and the signal strength of at least one second cell reported by these terminals is greater than the strength threshold, it can send activation indication information to the first network device to instruct the second cell in the deactivated state to switch to the activated state.

[0186] Step 906: Based on the activation indication information, the first network device switches at least one second cell from a deactivated state to an activated state to provide services for at least one second terminal.

[0187] After receiving the activation indication information, the first network device may switch the at least one second cell from a deactivated state to an activated state, wherein in the activated state, the at least one second cell provides a service for the at least one second terminal.

[0188] Among them, in the activated state, at least one second cell serving at least one second terminal may mean that the first network device performs data transmission with the at least one second terminal on the at least one second cell based on scheduling by the second network device.

[0189] Optionally, after activating at least one second cell, the first network device may also feed back a confirmation message regarding the activation indication information to the second network device, thereby notifying the second network device that at least one second cell has been activated, so that the second network device can subsequently schedule the first network device to transmit data on the at least one second cell.

[0190] Step 907: The second network device sends an activation notification to at least one second terminal, where the activation notification includes an identifier of at least one second cell.

[0191] The second network device may not only send activation indication information to the first network device, but may also send an activation notification to at least one second terminal served by at least one second cell, and the activation notification may carry an identifier of the at least one second cell. After receiving the activation notification, any second terminal may resume sending and receiving signals on the at least one second cell based on the activation notification.

[0192] The second network device may send an activation notification to at least one second terminal served by at least one second cell after sending the activation indication information or while sending the activation indication information or after receiving a confirmation message for the activation indication information.

[0193] In addition, in the embodiment of the present application, the activation notification can also be implemented through any one of RRC messages, MAC-CE, and DCI.

[0194] Step 908: The second terminal sends and receives signals on at least one second cell based on the activation notification.

[0195] After receiving the activation notification, the second terminal can confirm whether the identifier of at least one second cell carried in the activation notification includes the identifier of its own Scell ​​or the identifier of the cell in the SCG. If it includes the identifier of its own Scell ​​or the identifier of the cell in the SCG, the corresponding Scell ​​or the cell in the SCG is set to an activated state. Thereafter, the cell in the Scell ​​or SCG listens to the data sent by the first network device and sends data to the first network device.

[0196] Optionally, in some possible situations, if the first network device is in the off state, the second network device may also instruct the first network device to recover from the off state to the normal state or the energy-saving state. For example, when the load of the second network device is too high, the second network device may send a wake-up signal to the first network device, and the first network device may switch from the off state to the normal state after detecting the wake-up signal. Alternatively, the first network device switches from the off state to the energy-saving state after detecting the wake-up signal.

[0197] Alternatively, the wake-up signal may carry indication information of the state to be restored. When the indication information of the state to be restored indicates that the state to be restored is a normal state, the first network device switches from the shutdown state to the normal state. If the indication information of the state to be restored indicates that the state to be restored is an energy-saving state, the first network device switches from the shutdown state to the energy-saving state.
