Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a method and apparatus for switching working modes of a dual-connection network device in the field of communications. Background Art

[0002] With the development of science and technology, communication technology has been improved by leaps and bounds. Wireless communication technology has evolved for a long time. In the current wireless communication technology, in order to improve the information transmission rate, the main network equipment and the auxiliary network equipment are usually deployed in the same area. The terminal equipment can support simultaneous access to the main network equipment and the auxiliary network equipment, so that data can be transmitted with the main network equipment and the auxiliary network equipment at the same time. The randomness of the amount of communication data leads to the randomness of the load of the network equipment. When the amount of communication data is small, the data transmission rate can be met by using the main network equipment. Since the network equipment has a large static power consumption (that is, the internal energy loss of the network equipment when it is running at no load, such as the operating power loss of the power amplifier, intermediate frequency, radio frequency and other modules), in order to reduce the power consumption of the auxiliary network equipment, it is usually necessary to shut down certain hardware modules of the auxiliary network equipment.

[0003] In the related art, when the load of the auxiliary network device is less than a preset threshold, the auxiliary network device is turned off to reduce the power consumption of the auxiliary network device; when the load of the main network device is greater than the preset threshold or a mobile device with a high transmission rate requirement is connected, the auxiliary network device needs to be restarted. Due to the randomness of the data transmission volume, the load of the main and auxiliary network devices is too high or too low, which may lead to repeated shutdown operations on the auxiliary network device. Each time the auxiliary network device is turned off or started, the terminal needs to reconfigure the parameters of the auxiliary network device to be connected, resulting in data transmission delays. In this way, on the one hand, the shutdown time of the auxiliary network device is reduced and the user experience is reduced; on the other hand, when the delay is too large, even if the dual connection is turned on, the delay requirement cannot be met, and the energy of the auxiliary network device is wasted. Secondly, after the auxiliary network device is turned off, the terminal cannot detect the auxiliary network device information. When dual connection is enabled, in order to obtain the best matching auxiliary network device, the terminal device needs to access the secondary network device for the second time (that is, re-search the synchronization information of the auxiliary network device, re-read the system message, re-measure and report the area, etc.), which seriously causes data delay; in order to avoid the secondary access of the terminal device, the main network device randomly adds auxiliary network devices, which causes the auxiliary network devices added by the main network device to be unable to meet the higher data transmission speed, which also affects the data transmission rate. Summary of the invention

[0004] The present application provides a method and apparatus for switching working modes of a dual-connection network device, which switches from a first working mode to a second working mode when the load of the base station is small, and switches from the second working mode to the first working mode when the load of the base station is large, thereby effectively reducing the power consumption of the base station while ensuring the data transmission rate between the base station and the terminal.

[0005] In the first aspect, the present application provides a working mode conversion method for a dual-connected network device, which is applied to a first network device, and the method includes: determining whether a trigger condition for the working mode conversion is met; in response to meeting the trigger condition for the working mode conversion, sending a working mode conversion request to a second network device; sending first indication information for indicating the working mode conversion to a terminal connected to the second network device; the working modes include: a first working mode and a second working mode, wherein the first working mode is a non-energy-saving mode, and the second working mode is an energy-saving mode.

[0006] Therefore, the working mode conversion shown in the present application includes one of the following: conversion from the first working mode to the second working mode; conversion from the second working mode to the first working mode.

[0007] When the first network device in the dual connection system of the present application determines that the trigger condition for the working mode conversion is met, it sends a working mode conversion request to the second network device, so that the second network device performs the working mode conversion, so that under the condition of low load, the second network device enters the second working mode to save the power consumption of the network device, and under the condition of high load, the second network device enters the first working mode to improve the data transmission rate. At the same time, the first network device sends the first indication information of the working mode conversion to the terminal connected to the second network device, so that the terminal can maintain signal synchronization with the second network device in the second working mode. When the second network device enters the second working mode, the terminal does not need to delete the configuration parameters of the second network device, which is conducive to the terminal quickly accessing the second network device when restoring the first working mode, reducing the delay of the terminal accessing the second network device when the second working mode is converted to the first working mode, and thus facilitating the improvement of the data transmission rate between the terminal and the network device.

[0008] In combination with the first aspect, in a possible implementation, in the second working mode, the transmission period of the synchronization signal and the main system information MIB of the second network device and / or the measurement signal for radio resource management RRM is greater than the transmission period in the first working mode. Here, the synchronization signal includes PSS (Primary Synchronization Signal) and SSS (Secondary Synchronization Signal), and PSS and SSS are transmitted in SSB (Synchronization Signal Block) and configured at a fixed time slot position together with the PBCH channel (Physical Broadcast Channel). MIB (Master Information Block) is carried in the PBCH channel and sent.

[0009] In the second working mode, the second network device sends reference signals (such as CSI-RS), synchronization signals and MIB for radio resource management RRM at a transmission period greater than that in the first working mode, so that the second network device can turn on related devices when sending signals and turn off related devices when stopping sending signals, so as to achieve the purpose of reducing power consumption. In the second working mode, since the terminal can periodically measure the second network device to ensure synchronization with the second network device, it is not necessary to delete the configuration information of the second network device.

[0010] In combination with the first aspect, in a possible implementation manner, the method further includes: receiving response information of the working mode conversion request from the second network device.

[0011] In combination with the first aspect, in a possible implementation method, the trigger condition for the working mode conversion includes a trigger condition for converting from a first working mode to a second working mode, and the trigger condition for converting from the first working mode to the second working mode includes one or more of the following: the load or resource utilization of the first network device is lower than a first preset threshold value; the load or resource utilization of the second network device is lower than a second preset threshold value; the load or resource utilization of the first network device and the second network device are both lower than a third preset threshold value; the energy consumption of the second network device is higher than a fourth preset threshold value, and the load is lower than a fifth preset threshold value.

[0012] In combination with the first aspect, in a possible implementation manner, the operating mode conversion request includes requesting the second network device to enter the second operating mode.

[0013] At this time, in a possible implementation, the response information received from the second network device may include indication information indicating whether the second working mode can be entered at present. In some application scenarios, the second network device is currently transmitting data with the terminal and has not yet completed it. When entering the energy-saving mode at this time, it usually causes the data transmission between the terminal and the first network device to fail. In this optional implementation, the first network device can determine the current working state of the second network device by receiving the response information. When it is determined that the second network device is currently transmitting data, it can instruct the second network device to enter the energy-saving mode after the second network device completes the data transmission to avoid data transmission failure.

[0014] At this time, the above-mentioned response information also includes at least one of the following: common channel configuration information of the second network device in the second working mode; configuration information of the second network device for wireless resource management RRM measurement in the second working mode; configuration information of the second network device for channel state information CSI measurement in the second working mode.

[0015] At this time, the above-mentioned first indication information includes at least one of the following: used to indicate the status information of the cells in the cell set SCG of the second network device in the second working mode; used to indicate the status information of the carrier of the second network device in the second working mode; used to indicate the configuration information used for wireless resource management RRM measurement by the second network device in the second working mode; used to indicate the configuration information used for channel state information CSI measurement by the second network device in the second working mode; used to indicate the common channel configuration information of the second network device in the second working mode.

[0016] Under the condition of converting from the first working mode to the second working mode, the working mode conversion method shown in the present application also includes: receiving second indication information from the terminal, the second indication information is used to indicate that the terminal configuration is complete; based on the received second indication information, sending third indication information to the second network device, the third indication information is used to indicate that the terminal configuration is complete. By sending the third indication information indicating that the terminal configuration is complete to the second network device, the second network device can reserve a certain time to wait for the terminal to configure, thereby improving the success rate of terminal configuration.

[0017] In combination with the first aspect, in a possible implementation method, the triggering condition for the working mode conversion includes a triggering condition for converting from the second working mode to the first working mode, and the triggering condition for converting from the second working mode to the first working mode includes one or more of the following: the load or resource utilization of the first network device is higher than a preset threshold value; the data transmission rate requested by the terminal is higher than the data transmission rate of the first network device; the energy consumption of the first network is greater than a preset threshold value, and in the first working mode, the sum of the energy consumption of the first network device and the second network device is less than the energy consumption of the first network.

[0018] In combination with the first aspect, in a possible implementation manner, the operating mode conversion request includes requesting the second network device to enter the first operating mode.

[0019] At this time, in a possible implementation, the response information received from the second network device may include indication information indicating whether the first working mode can be currently entered. In some application scenarios, when the second network device is currently unable to perform the first working mode due to configuration information errors or other reasons, the first network device can determine the current working state of the second network device by receiving the response information. When it is determined that the second network device is currently unable to enter the first working mode, the second network device can be instructed to enter the energy-saving mode after the second network device is updated, so as to avoid the terminal being unable to access the second network device, or being unable to perform data transmission with the second network device after accessing the second network device, thereby improving data transmission efficiency.

[0020] At this time, the above-mentioned response information also includes at least one of the following items: configuration information of the physical random access channel PRACH of the second network device in the first working mode; common channel configuration information of the second network device in the first working mode; configuration information of the second network device for wireless resource management RRM measurement in the first working mode.

[0021] At this time, the first indication information includes at least one of the following: information used to indicate the cell status in the cell set SCG of the second network device in the first working mode; information used to indicate the status of the carrier of the second network device in the first working mode; information used to indicate the common channel configuration information of the second network device in the first working mode; configuration information used to indicate the radio resource management RRM measurement of the second network device in the first working mode; configuration information used to indicate the channel state information CSI measurement of the second network device in the first working mode.

[0022] In combination with the first aspect, under the condition of converting from the second working mode to the first working mode, the working mode conversion method shown in the present application also includes: receiving second indication information from the terminal, and the second indication information is used to indicate that the terminal configuration is completed.

[0023] In combination with the first aspect, in a possible implementation, when entering the second working mode from the first working mode for the first time, the parameters of the second network device in the second working mode can be pre-configured. The method for pre-configuring parameters includes: receiving configuration information of the second network device in the second working mode from the second network device; sending the configuration information of the second network device in the second working mode to the terminal; the configuration information of the second network device in the second working mode includes one or more groups of configuration parameters; the configuration parameters include: a configuration identifier, and the configuration parameters also include one or more of the common channel configuration information corresponding to the configuration identifier, the configuration information for radio resource management RRM measurement, and the configuration information for channel state information CSI measurement; the first indication information includes: the configuration identifier.

[0024] By pre-configuring the parameters of the first working mode, the present application can make it unnecessary to reconfigure information such as RRM measurement information, common channel information, etc. in the second working mode or the first working mode every time during the working mode conversion process, that is, the number of information interactions between the second network device and the first network device, and between the first network device and the terminal is reduced, which is conducive to reducing signaling expenses.

[0025] In combination with the first aspect, under the condition that the parameters of the second network device have been pre-configured, when the second network device enters the second working mode, the first network device can receive response information for entering the second working mode from the second network device, and the response information includes a configuration identifier.

[0026] In combination with the first aspect, under the condition that the parameters of the second network device have been pre-configured, when the second network device enters the second working mode, the first indication information also includes at least one of the following: status information for indicating cells in the cell set SCG of the second network device in the second working mode; status information for indicating the carrier of the second network device in the second working mode.

[0027] In combination with the first aspect, under the condition that the parameters of the second network device have been pre-configured, when the second network device enters the first working mode, the first network device can receive response information from the second network device to enter the first working mode, and the response information includes a configuration identifier in the second working mode.

[0028] In combination with the first aspect, under the condition that the parameters of the second network device have been pre-configured, when the second network device enters the first working mode, the first indication information also includes at least one of the following: information used to indicate the cell status in the cell set SCG of the second network device in the first working mode; information used to indicate the status of the carrier of the second network device in the first working mode.

[0029] In the second aspect, the present application provides a working mode conversion method for a dual-connected network device, which is applied to a first network device, the method comprising: receiving a working mode conversion request from a second network device; based on the working mode conversion request, sending first indication information for indicating a working mode conversion to a terminal connected to the second network device, the working modes comprising: a first working mode and a second working mode, wherein the first working mode is a non-energy-saving working mode, and the second working mode is an energy-saving working mode.

[0030] Therefore, the working mode conversion includes one of the following: conversion from the first working mode to the second working mode; conversion from the second working mode to the first working mode.

[0031] Different from the working mode conversion method shown in the first aspect, the working mode conversion shown in the second aspect can be initiated by the second network device. That is, after determining that the working mode conversion condition is met, the second network device can send a working mode conversion request to the first network device. Thus, the first network device and the second network device can monitor the power consumption of the dual-connection system at the same time, improve the monitoring effect, and help reduce the power consumption of the dual-connection system.

[0032] In combination with the second aspect, in a possible implementation, in the second working mode, the transmission period of the synchronization signal and the main system information MIB of the second network device and / or the measurement signal for radio resource management RRM is greater than the transmission period in the first working mode. In this possible implementation, in the second working mode, the second network device turns on the relevant device when sending a signal and turns off the relevant device when stopping sending a signal, so as to achieve the purpose of reducing power consumption. Since the terminal can measure the second network device to ensure synchronization with the second network device, it is not necessary to delete the configuration information of the second network device.

[0033] In combination with the second aspect, in a possible implementation method, the triggering condition for the working mode conversion includes a triggering condition for converting from a first working mode to a second working mode, and the triggering condition for converting from the first working mode to the second working mode includes one or more of the following: the load or resource utilization of the first network device is lower than a first preset threshold value; the load or resource utilization of the second network device is lower than a second preset threshold value; the load or resource utilization of the first network device and the second network device are both lower than a third preset threshold value; the energy consumption of the second network device is higher than a fourth preset threshold value, and the load is lower than a fifth preset threshold value.

[0036] At this time, the above-mentioned first indication information includes at least one of the following: used to indicate the status information of the cells in the cell set SCG of the second network device in the second working mode; used to indicate the status information of the carrier of the second network device in the second working mode; used to indicate the configuration information used for wireless resource management RRM measurement by the second network device in the second working mode; used to indicate the configuration information used for channel state information CSI measurement by the second network device in the second working mode; used to indicate the common channel configuration information of the second network device in the second working mode.

[0037] In combination with the second aspect, under the condition of converting from the first working mode to the second working mode, in a possible implementation, the working mode conversion method shown in the present application also includes: receiving second indication information from the terminal, the second indication information is used to indicate that the terminal configuration is complete; based on the received second indication information, sending third indication information to the second network device, the third indication information is used to indicate that the terminal configuration is complete. By sending the third indication information indicating that the terminal configuration is complete to the second network device, the second network device can reserve a certain amount of time to wait for the terminal to configure, thereby improving the success rate of terminal configuration.

[0038] It is worth noting here that in some application scenarios, in order to quickly enter the second working mode, the second network device does not need to enter the second working mode after receiving the third indication information. The second network device can directly enter the second working mode after receiving the response information of the first network device.

[0039] In combination with the second aspect, in a possible implementation, when entering the second working mode from the first working mode for the first time, the parameters of the second network device in the second working mode can be pre-configured. The method for pre-configuring parameters includes: receiving configuration information of the second network device in the second working mode from the second network device; sending the configuration information of the second network device in the second working mode to the terminal; the configuration information of the second network device in the second working mode includes one or more groups of configuration parameters; the configuration parameters include: a configuration identifier, the configuration parameters also include one or more of the common channel configuration information corresponding to the configuration identifier, the configuration information for radio resource management RRM measurement and the configuration information for channel state information CSI measurement; the first indication information includes: the configuration identifier.

[0040] By pre-configuring the parameters of the first working mode, the present application can make it unnecessary to reconfigure information such as RRM measurement information, common channel information, etc. in the second working mode or the first working mode every time during the working mode conversion process, that is, the number of information interactions between the second network device and the first network device, and between the first network device and the terminal is reduced, which is conducive to reducing signaling expenses.

[0041] In combination with the second aspect, under the condition that the parameters of the second network device have been pre-configured, when the second network device enters the second working mode, the working mode conversion request received from the second network device also includes a configuration identifier.

[0042] In combination with the second aspect, under the condition that the parameters of the second network device have been pre-configured, when the second network device enters the second working mode, the first indication information also includes at least one of the following: status information for indicating cells in the cell set SCG of the second network device in the second working mode; status information for indicating the carrier of the second network device in the second working mode.

[0043] In the third aspect, the present application provides a working mode conversion method for a dual-connected network device, which is applied to a second network device, the method comprising: receiving a working mode conversion request from a first network device; based on the working mode conversion request, sending a response information of the working mode conversion request to the first network device; the working modes include: a first working mode and a second working mode, wherein the first working mode is a non-energy-saving working mode, and the second working mode is an energy-saving working mode.

[0044] Therefore, the working mode conversion includes one of the following: conversion from the first working mode to the second working mode; conversion from the second working mode to the first working mode.

[0045] In the dual connection system of the present application, the second network device can receive a working mode conversion request from the first network device to convert the working mode, so that under the condition of low load, the second network device enters the second working mode to save the power consumption of the network device, and under the condition of high load, the second network device enters the first working mode to improve the data transmission rate. At the same time, after receiving the working mode conversion request, the second network device can send a response message to the first network device, so that the first network device can send a first indication message to the terminal connected to the second network device based on the response message, so that in the second working mode, the terminal can maintain signal synchronization with the second network device. When the second network device enters the second working mode, the terminal does not need to delete the configuration parameters of the second network device, which is conducive to the terminal quickly accessing the second network device when restoring the first working mode, reducing the delay of the terminal accessing the second network device when the second working mode is converted to the first working mode, thereby facilitating the improvement of the data transmission rate between the terminal and the network device.

[0046] In combination with the third aspect, in a possible implementation, in the second working mode, the transmission period of the synchronization signal and the main system information MIB of the second network device and / or the measurement signal for radio resource management RRM is greater than the transmission period in the first working mode. In this possible implementation, in the second working mode, the second network device turns on the relevant device when sending a signal and turns off the relevant device when stopping sending a signal, so as to achieve the purpose of reducing power consumption. Since the terminal can measure the second network device to ensure synchronization with the second network device, it is not necessary to delete the configuration information of the second network device.

[0047] In combination with the third aspect, in a possible implementation, the operating mode conversion request includes requesting the second network device to enter the second operating mode.

[0048] At this time, in some possible implementations, after receiving the working mode conversion request, the second network device may include indication information indicating whether it can currently enter the second working mode in the response information sent to the first network device based on its current working state. In some application scenarios, the second network device is currently transmitting data with the terminal and has not yet completed it, and when it enters the energy-saving mode at this time, the data transmission between the terminal and the second network device fails. By sending the indication information of whether to enter the second working mode, the first network device can instruct the second network device to enter the energy-saving mode after the second network device completes the data transmission, thereby avoiding data transmission failure.

[0049] At this time, the above-mentioned response information also includes at least one of the following: common channel configuration information of the second network device in the second working mode; configuration information of the second network device for wireless resource management RRM measurement in the second working mode; configuration information of the second network device for channel state information CSI measurement in the second working mode.

By sending the third indication information indicating that the terminal configuration is complete to the second network device, the second network device can reserve a certain amount of time to wait for the terminal to be configured, thereby improving the success rate of terminal configuration.

[0051] It is worth noting here that in some application scenarios, in order to quickly enter the second working mode, the second network device does not need to enter the second working mode after receiving the third indication information. The second network device can directly enter the second working mode after receiving the request sent by the first network device to convert from the first working mode to the second working mode.

[0052] In combination with the third aspect, in a possible implementation, the operating mode conversion request includes requesting the second network device to enter the first operating mode.

[0053] At this time, in some possible implementations, when the second working mode is converted to the first working mode, after receiving the working mode conversion request, the second network device sends a response message to the first network device based on its current working state, which may include indication information indicating whether the first working mode can be entered at present. In some application scenarios, when the second network device is currently unable to perform the first working mode due to configuration information errors or other reasons, the first network device is notified through the indication information, so that when the first network device determines that the second network device is currently unable to enter the first working mode, it can instruct the second network device to enter the energy-saving mode after the second network device is updated, so as to avoid the terminal being unable to access the second network device, or being unable to transmit data with the second network device after accessing the second network device, thereby improving the data transmission efficiency.

[0056] In combination with the third aspect, in a possible implementation, when entering the second working mode from the first working mode for the first time, the parameters of the second network device in the second working mode can be pre-configured. The method of pre-configuring parameters performed by the second network device includes: sending configuration information of the second network device in the second working mode to the first network device; the configuration information of the second network device in the second working mode includes one or more groups of configuration parameters; the configuration parameters include: a configuration identifier, and the configuration parameters also include one or more of the common channel configuration information corresponding to the configuration identifier, the configuration information for radio resource management RRM measurement, and the configuration information for channel state information CSI measurement; the response information includes: the configuration identifier.

[0061] Therefore, the working mode conversion includes one of the following: conversion from the first working mode to the second working mode; conversion from the second working mode to the first working mode.

[0062] Different from the working mode conversion method shown in the third aspect, the working mode conversion shown in the fourth aspect can be initiated by the second network device. That is, after the second network device determines that the working mode conversion condition is met, it can send a working mode conversion request to the first network device. Thus, the first network device and the second network device can monitor the power consumption of the dual-connection system at the same time, improve the monitoring effect, and help reduce the power consumption of the dual-connection system.

[0063] In conjunction with the fourth aspect, in a possible implementation, in the second working mode, the transmission period of the synchronization signal and the main system information MIB of the second network device and / or the measurement signal for radio resource management RRM is greater than the transmission period in the first working mode. In this possible implementation, in the second working mode, the second network device turns on the relevant device when sending a signal and turns off the relevant device when stopping sending a signal, so as to achieve the purpose of reducing power consumption. Since the terminal can measure the second network device to ensure synchronization with the second network device, it is not necessary to delete the configuration information of the second network device.

[0064] In combination with the fourth aspect, in a possible implementation method, the trigger condition for the working mode conversion includes a trigger condition for converting from a first working mode to a second working mode, and the trigger condition for converting from the first working mode to the second working mode includes one or more of the following: the load or resource utilization of the first network device is lower than a first preset threshold value; the load or resource utilization of the second network device is lower than a second preset threshold value; the load or resource utilization of the first network device and the second network device are both lower than a third preset threshold value; the energy consumption of the second network device is higher than a fourth preset threshold value, and the load is lower than a fifth preset threshold value.

[0065] In combination with the fourth aspect, in a possible implementation, the operating mode conversion request includes requesting the second network device to enter the second operating mode.

[0066] At this time, the working mode conversion request sent by the second network device also includes at least one of the following: common channel configuration information of the second network device in the second working mode; configuration information for wireless resource management RRM measurement of the second network device in the second working mode; configuration information for channel state information CSI measurement of the second network device in the second working mode.

[0067] In combination with the fourth aspect, under the condition of converting from the first working mode to the second working mode, the working mode conversion method shown in the present application also includes: receiving third indication information from the first network device, the third indication information is used to indicate that the terminal configuration is complete; based on the third indication information, entering the second working mode. By sending the third indication information indicating that the terminal configuration is complete to the second network device, the second network device can reserve a certain amount of time to wait for the terminal to be configured, thereby improving the success rate of terminal configuration.

[0068] It is worth noting here that in some application scenarios, in order to quickly enter the second working mode, the second network device does not need to enter the second working mode after receiving the third indication information. The second network device can directly enter the second working mode after receiving the response information sent by the first network device.

[0069] In combination with the fourth aspect, in a possible implementation, when entering the second working mode from the first working mode for the first time, the parameters of the second network device in the second working mode can be pre-configured. The method of pre-configuring parameters performed by the second network device includes: sending the configuration information of the second network device in the second working mode to the first network device; the configuration information of the second network device in the second working mode includes one or more groups of configuration parameters; the configuration parameters include: a configuration identifier, and the configuration parameters also include one or more of the common channel configuration information corresponding to the configuration identifier, the configuration information for radio resource management RRM measurement, and the configuration information for channel state information CSI measurement; the response information includes: the configuration identifier.

[0070] By pre-configuring the parameters of the second working mode, the present application can make it unnecessary to reconfigure information such as RRM measurement information, common channel information, etc. in the second working mode or the first working mode every time during the working mode conversion process, that is, the number of information interactions between the second network device and the first network device, and between the first network device and the terminal is reduced, which is conducive to reducing signaling expenses.

[0071] In combination with the fourth aspect, under the condition that the parameters of the second network device have been pre-configured, when the second network device enters the second working mode, the working mode conversion request sent by the second network device to the first network device also includes a configuration identifier.

[0072] In a fifth aspect, the present application provides a method for converting the working mode of a dual-connected network device, which is applied to a terminal, and the method includes: receiving first indication information for instructing the working mode conversion of a second network device from a first network device; based on the first indication information, configuring parameters for accessing the second network; the working modes include: a first working mode and a second working mode, wherein the first working mode is a non-energy-saving working mode, and the second working mode is an energy-saving working mode.

[0073] Therefore, the working mode conversion includes one of the following: conversion from the first working mode to the second working mode; conversion from the second working mode to the first working mode.

[0074] By receiving the first indication information from the first network device, the terminal can configure the parameters of the second network device in the second working mode or in the first working mode, so that the terminal can maintain signal synchronization with the second network device in the second working mode. When the second network device enters the second working mode, the terminal does not need to delete the configuration parameters of the second network device, which is conducive to the terminal quickly accessing the second network device when restoring the first working mode, reducing the delay of the terminal accessing the second network device when switching from the second working mode to the first working mode, and further facilitating to improve the data transmission rate between the terminal and the network device.

[0075] In conjunction with the fifth aspect, in a possible implementation, in the second working mode, the transmission period of the synchronization signal and the main system information MIB of the second network device and / or the measurement signal for radio resource management RRM is greater than the transmission period in the first working mode. In this possible implementation, in the second working mode, the second network device turns on the relevant device when sending a signal and turns off the relevant device when stopping sending a signal, so as to achieve the purpose of reducing power consumption. Since the terminal can measure the second network device to ensure synchronization with the second network device, it is not necessary to delete the configuration information of the second network device.

[0076] In combination with the fifth aspect, in a possible implementation method, the working mode conversion includes converting from the first working mode to the second working mode; the first indication information includes at least one of the following: status information for indicating cells in the cell set SCG of the second network device in the second working mode; status information for indicating the carrier of the second network device in the second working mode; configuration information for indicating the second network device for radio resource management RRM measurement in the second working mode; configuration information for indicating the second network device for channel state information CSI measurement in the second working mode; and common channel configuration information for indicating the second network device in the second working mode.

[0077] In combination with the fifth aspect, in a possible implementation method, the working mode conversion includes converting from the second working mode to the first working mode, and the first indication information includes at least one of the following: information used to indicate the cell status in the cell set SCG of the second network device in the first working mode; information used to indicate the status of the carrier of the second network device in the first working mode; information used to indicate the common channel configuration information of the second network device in the first working mode; configuration information used to indicate the radio resource management RRM measurement of the second network device in the first working mode; configuration information used to indicate the channel state information CSI measurement of the second network device in the first working mode.

[0078] In combination with the fifth aspect, in a possible implementation manner, the method further includes: sending second indication information to the first network device, where the second indication information is used to indicate that the terminal configuration is completed.

[0079] In combination with the fifth aspect, in a possible implementation manner, the method further includes: sending a random access request to the second network device.

[0080] In combination with the fifth aspect, in a possible implementation, when entering the second working mode from the first working mode for the first time, the parameters of the second network device in the second working mode can be pre-configured. The method of pre-configuring parameters performed by the terminal includes: receiving configuration information of the second network device in the second working mode from the first network device; the configuration information of the second network device in the second working mode includes one or more groups of configuration parameters; the configuration parameters include: a configuration identifier, the configuration parameters also include one or more of the common channel configuration information corresponding to the configuration identifier, the configuration information for radio resource management RRM measurement and the configuration information for channel state information CSI measurement; the first indication information includes: the configuration identifier.

[0081] By pre-configuring the parameters of the second working mode, the present application can make it unnecessary to reconfigure information such as RRM measurement information, common channel information, etc. in the second working mode or the first working mode every time during the working mode conversion process, that is, the number of information interactions between the second network device and the first network device, and between the first network device and the terminal is reduced, which is conducive to reducing signaling expenses.

[0082] In combination with the fifth aspect, under the condition that the parameters of the second network device have been pre-configured, in a possible implementation method, when the second network device enters the second working mode, the first indication information also includes at least one of the following: status information for indicating the cells in the cell set SCG of the second network device in the second working mode; status information for indicating the carrier of the second network device in the second working mode.

[0083] In combination with the fifth aspect, under the condition that the parameters of the second network device have been pre-configured, in a possible implementation method, when the second network device enters the first working mode, the first indication information also includes at least one of the following: information used to indicate the cell status in the cell set SCG of the second network device in the first working mode; information used to indicate the status of the carrier of the second network device in the first working mode.

[0084] It should be noted that the first working mode described in the first to fifth aspects above can be a dual connection working mode, and the second working mode can be an energy-saving working mode. The first working mode and the second working mode can also be other working modes, which are not specifically limited here.

[0103] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0104] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, new radio interface (NR) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), future fifth generation (5G) system and any combination of the above systems.

[0105] The terminal device in the embodiments of the present application may also be referred to as: user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, etc.

[0106] The terminal device may be a device that provides voice / data connectivity to users, such as a handheld device or vehicle-mounted device with wireless connection function. At present, some examples of terminals are: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in future 5G networks or future evolved public land mobile communication networks (public land mobile The embodiments of the present application do not limit this.

[0107] The network device (first network device and second network device) in the embodiment of the present application can be a device for communicating with a terminal device. The network device can also be called an access network device or a wireless access network device. It can be an evolved base station (evolved NodeB, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (cloud radio access network, CRAN) scenario, or the access device can be a relay station, an access point, a vehicle-mounted device, a wearable device, and an access device in a future 5G network or an access device in a future evolved PLMN network, etc. It can be an access point (access point, AP) in a WLAN, or it can be a gNB in ​​a new wireless system (new radio, NR) system. The embodiment of the present application is not limited.

[0108] In addition, in the embodiment of the present application, the network device (the first network device and the second network device) may also be a device in a RAN (Radio Access Network), or in other words, a RAN node that connects the terminal device to a wireless network. For example, as an example and not a limitation, the network devices include: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP), etc.

[0109] The access device provides services for the cell, and the terminal device communicates with the access device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell may be a cell corresponding to the access device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0110] In addition, multiple cells can work at the same frequency on a carrier in an LTE system or a 5G system at the same time. In some special scenarios, the above-mentioned carrier and cell concepts can also be considered equivalent. For example, in a carrier aggregation (CA) scenario, when a secondary carrier is configured for a terminal device, the carrier index of the secondary carrier and the cell identification (cell ID) of the secondary cell working on the secondary carrier will be carried at the same time. In this case, the concepts of carrier and cell can be considered equivalent, for example, the terminal device accessing a carrier is equivalent to accessing a cell.

[0111] Please refer to Figure 1a , Figure 1aA schematic diagram of a network architecture applied to an embodiment of the present application is shown. Figure 1a In the present invention, a terminal device can access two network devices at the same time, and this access mode is called dual-connectivity (DC). Among the two network devices, the first network device is responsible for interacting with the terminal device through radio resource control messages and interacting with the core network control plane entity, which can also be called the primary network device, and the other network device is the second network device, which can also be called the secondary network device.

[0112] Similarly, a terminal device may also simultaneously have communication connections with multiple access devices and may send and receive data, which may be referred to as multi-connectivity or multi-link (MC). Among the multiple access devices, there may be an access device responsible for interacting with the terminal device via wireless resource control messages and for interacting with the core network control plane entity. In this case, the network device may be referred to as the primary network device, and the remaining network devices may be referred to as secondary network devices.

[0113] In an embodiment of the present application, the first network device and the second network device may be network devices of the same wireless access type. For example, the first network device and the second network device may be network devices of an LTE system, or may be network devices of an NR system. The primary network device and the secondary network device may also be network devices of different wireless access types. For example, the primary network device is a network device of an LTE system, and the secondary network device is a network device of an NR system; or, the primary network device is a network device of an NR system, and the secondary network device is a network device of an LTE system. The primary network device and the secondary network device may communicate with each other through an interface, so that the primary network device may obtain various information of the secondary network device. This information may include, for example, but is not limited to, the load amount, resource utilization rate, etc. of the secondary network device. Similarly, the secondary network device may also obtain information such as load amount, resource utilization rate, etc. of the primary network device.

[0114] The following briefly introduces three specific multiple RATs dual connectivity (MR-DC) architectures applicable to this application:

[0115] 1) E-UTRA NR DC (EN-DC for short) architecture

[0116] This architecture can also be called option 3 series. In this architecture, LTE network equipment (such as LTE eNB) is used as the main network equipment, NR network equipment (such as gNB) is used as the auxiliary network equipment for DC, and the core network equipment is EPC. Among them, LTE eNB is connected to EPC through S1-C interface or S1-U interface, providing air interface transmission resources for data between terminal equipment and EPC. Alternatively, LTE eNB is connected to EPC through S1-C interface or S1-U interface, and gNB is connected to EPC through S1-U interface, providing air interface transmission resources for data transmission between terminal equipment and EPC.

[0117] 2) NR E-UTRA DC (NE-DC) architecture

[0118] This architecture can also be called option 4 series. In this architecture, NR network equipment (such as gNB) is used as the main network equipment, LTE network equipment (such as ng-eNB) is used as the auxiliary network equipment for DC, and the core network equipment is 5GC. Among them, gNB is connected to 5GC through NG-C interface or NG-U interface, providing air interface transmission resources for data transmission between terminal equipment and 5GC; or, gNB is connected to 5GC through NG-C interface or NG-U interface, and ng-eNB is connected to 5GC through NG-U interface, providing air interface transmission resources for data transmission between terminal equipment and 5GC.

[0119] 3) Next Generation E-UTRA NR DC (NG NE-DC) architecture

[0120] This architecture can also be called option 7 series. That is, LTE network equipment (such as ng-gNB) is used as the main network equipment, NR network equipment (such as gNB) is used as the auxiliary network equipment for DC, and the core network equipment is 5GC. Among them, ng-eNB is connected to 5GC through NG-C interface or NG-U interface, providing air interface transmission resources for data transmission between terminal equipment and 5GC; or, ng-eNB is connected to 5GC through NG-C interface or NG-U interface, and gNB is connected to 5GC through NG-U interface, providing air interface transmission resources for data transmission between terminal equipment and 5GC.

[0121] In a possible implementation, the first network device and the second network device may be access network devices deployed at different sites. Figure 1a In FIG. 1 , the first network device and the second network device are arranged at different sites. In this case, each network device includes a processor and a transceiver to receive various signals from a terminal, or to send signals to a terminal, and to process the signals. Figure 1b As shown, Figure 1b The internal structure diagram of the first network device and the second network device and the terminal deployed at different sites is shown. Figure 1b It can be seen that the first network device communicates with the terminal through transceiver 1; the second network device communicates with the terminal through transceiver 2; and the terminal can communicate with the first network device and the second network device at the same time through transceiver 3.

[0122] In another possible implementation, the first network device and the second network device may also be network devices deployed at the same site. Figure 1c As shown, Figure 1c A schematic diagram of another network architecture applied to an embodiment of the present application is shown. Figure 1c In FIG. 1 , the first network device and the second network device are arranged at the same site. In this case, the first network device and the second network device can share the same transceiver to communicate with the terminal. Figure 1d As shown, Figure 1d The figure shows the internal structure diagram of the first network device, the second network device and the terminal deployed at the same site. Figure 1d As can be seen from the figure, the first network device includes a processor 1, and the second network device includes a processor 2. The two share a transceiver 3. That is, the first network device and the second network device both communicate with the terminal through the transceiver 3.

[0123] exist Figure 1a-1d In the network devices shown, the first network device and the second network device are not fixed, that is, in some cases (for example, when the second network device is responsible for exchanging radio resource control messages with the terminal device), the second network device can be used as the main network device and the first network device can be used as the auxiliary network device. No specific limitation is made here.

[0124] exist Figure 1a-1dIn the network device shown, the auxiliary network device can have two working modes, a first working mode and a second working mode. Among them, in the first working mode, the auxiliary network device communicates and transmits data with the terminal, which is also called a non-energy-saving working mode. Here, the non-energy-saving working mode may include a multi-connection working mode, a dual-connection working mode, etc. In the second working mode, the auxiliary network device does not transmit data with the terminal, which is also called an energy-saving working mode. In order to explain the present application more clearly, the first working mode is referred to as the dual-connection working mode and the second working mode is referred to as the energy-saving working mode in the following embodiments to elaborate on the present application in detail. It should be noted that the first working mode and the second working mode in the present application can also be named by other names, as long as they conform to the working methods of the first working mode and the second working mode, they all fall within the scope of the first working mode and the second working mode shown in the present application.

[0125] In the dual connection working mode, the network device has a high power consumption. When the load of the network device is low, there is no need to transmit data to the terminal through the dual connection, and only the main network device is sufficient to bear the load, the auxiliary network device may be unloaded or the load is lower than the preset value. At this time, the devices such as power amplifiers and radio frequency units in the auxiliary network device still have a large static power consumption, so that the power consumption of the auxiliary network device will not be reduced due to the reduction of the low load. If the above-mentioned device with excessive static power consumption is turned off when the auxiliary network device is unloaded, the auxiliary network device needs to delete the configuration information of the terminal connected to the auxiliary network device; when the auxiliary network device is turned on so that the terminal restores the dual connection, the auxiliary network device needs to re-add the configuration information of the terminal connected to the auxiliary network device. In this way, when the terminal accesses the auxiliary network device to restore the dual connection, the delay is serious. For example, the delay is usually up to 100 milliseconds or more. In a specific application scenario, when a user needs high-speed network download, the delay of the terminal accessing the auxiliary network device is serious, which greatly reduces the user's data download speed and reduces the user experience.

[0126] In the dual connection working mode, the terminal can simultaneously transmit data with the main network device and the auxiliary network device to improve the data transmission rate of the terminal network. In the energy-saving working mode, the auxiliary network device periodically turns off or turns on the hardware modules with high static power consumption in the auxiliary network device, such as medium radio frequency devices, etc., to achieve the purpose of reducing power consumption of the auxiliary network device. At the same time, in the energy-saving working mode, the auxiliary network device sends radio resource management (Radio resource management, RRM) measurement reference signals and synchronization signals / broadcast channels (SS / PBCH block, SSB) at a period greater than that of the dual connection working mode. At this time, the terminal cannot transmit data with the auxiliary network device, but can measure the auxiliary network device to maintain synchronization with the auxiliary network device.

[0127] The present application enables the auxiliary network device to enter energy-saving mode when the load is low, and the terminal configuration information stored in the auxiliary network device is not released, so that when the auxiliary network device restores the dual connection mode, the terminal can quickly establish a connection with the auxiliary network device, thereby improving the data transmission rate of the terminal and thus improving the user experience.

[0128] It should be noted that Figure 1a-1d In the figure shown, the first network device (i.e., the main network device) is an LTE network device, and the second network device (i.e., the auxiliary network device) is an NR network device. The present application is not limited to this. It can also be a combination of other types of network devices.

[0129] Next, we will combine Figure 2-Figure 5 , description is given by taking the first network device as the main network device and the second network device as the auxiliary network device as an example.

[0130] Figure 2 A schematic flow chart of a conversion method from a dual connection working mode to an energy-saving working mode provided in an embodiment of the present application is shown. It should be understood that Figure 2 The steps or operations of the conversion method from the dual connection working mode to the energy-saving working mode are shown, but these steps or operations are only examples, and the embodiment of the present application can also perform other operations or Figure 2 The deformation of each operation in . Figure 2 As shown, the method for converting from the dual connection working mode to the energy-saving working mode may include steps 201-207.

[0131] 201. A first network device determines whether a trigger condition for switching from a dual connection working mode to a power-saving working mode is met.

[0132] In this embodiment, the triggering condition for switching from the dual connection working mode to the energy-saving working mode may include one or more of the following:

[0133] The load or resource utilization of the first network device is lower than the first preset threshold value; the load or resource utilization of the second network device is lower than the second preset threshold value; the load or resource utilization of the first network device and the second network device are both lower than the third preset threshold value; the energy consumption of the second network device is higher than the fourth preset threshold value, and the load is lower than the fifth preset threshold value.

[0134] Specifically, the load of the first network device or the load of the second network device can be considered as the communication data transmission volume between the terminal. When the load of the first network device is lower than the first preset threshold value, or the load of the second network device is detected to be lower than the second preset threshold value, or the load of the first network device and the second network device is detected to be lower than the third preset threshold value, it means that the terminal data transmission volume is low, and the first network device alone is sufficient to bear the data transmission with the terminal, and the data transmission rate is not less than the preset threshold. At this time, the second network device can be triggered to enter the energy-saving working mode.

[0135] The resources in the above resource utilization rate may include, as examples, but are not limited to: resources allocated or reserved for the terminal device, a user plane connection dedicated to the terminal device between the core network, etc., which is not specifically limited in the embodiments of the present application. Among them, the resources allocated or reserved for the terminal device may be, for example, air interface transmission resources, NG-U interface transmission resources, etc. The user plane connection dedicated to the terminal device between the core network may include, for example, transport layer information, data transmission channel, NG-U transport layer address information allocated to the terminal device, and at least one of the NG-U transport layer address information allocated by the core network to the terminal device.

[0136] The resource utilization of the first network device and the second network device may also include frequency domain resource utilization and time domain resource utilization. The time domain resource may be one or more symbols, one or more time slots, one or more mini time slots, or one or more subframes. The frequency domain resource may be one or more RBs, one or more REs, one or more carriers, one or more cells, or one or more bandwidth parts (BWPs).

[0137] When the resource utilization of the first network device is lower than the first preset threshold value, the resource utilization of the second network device is lower than the second preset threshold value, and the resource utilization of the first network device and the second network device is lower than the third preset threshold value, it indicates that the terminal data transmission volume is low, and the first network device alone is sufficient to bear the data transmission with the terminal, and the data transmission rate is not less than the preset threshold value. At this time, the second network device can be triggered to enter the energy-saving working mode.

[0138] 202. When detecting that a trigger condition for converting from the dual connection working mode to the energy-saving working mode is met, the first network device sends a working mode conversion request for converting from the dual connection working mode to the energy-saving working mode to the second network device.

[0139] In this embodiment, when the first network device detects that at least one trigger condition shown in 201 is met, the first network device may send a request to enter the energy-saving working mode to the first network device.

[0140] In a possible implementation, the first network device may send bit stream data to the second network device to directly instruct the second network device to enter the energy-saving mode.

[0141] In one possible implementation, the first network device may send a request to the second network device in the form of a bitmap, and at the same time use a bit to inquire whether the second network device can enter the energy-saving mode. In some application scenarios, when the first network device detects that the load or resource utilization of the second network device is lower than a certain threshold, the data transmission between the second network device and a terminal may not be completed. Entering the energy-saving mode at this time usually results in data transmission failure between the terminal. The first network device can request the second network device to enter the energy-saving mode by inquiring, and can enter the energy-saving mode after the second network device completes the data transmission, thereby avoiding data transmission failure.

[0142] In one possible implementation, when the first network device sends a request to the second network device to enter the energy-saving mode, it may also include configuration parameters that need to be returned by the second network device. When the second network device enters the energy-saving working mode, various parameters need to be reconfigured. Thus, the terminal synchronizes with the second network device based on the configuration parameters in the energy-saving working mode. Specifically, the first network device may request the second network device to return configuration parameters including but not limited to at least one of the following: common channel configuration information of the second network device in the energy-saving working mode; configuration information of the second network device for radio resource management RRM measurement in the energy-saving working mode; configuration information of the second network device for channel state information CSI measurement in the energy-saving working mode.

[0143] The common channel configuration information includes but is not limited to the transmission period of the synchronization signal carried by the common channel and the system message.

[0144] The information used for RRM measurement includes the resource index, measurement period, measurement bandwidth, etc. for the channel state information reference signal CSI-RS, including but not limited to: subcarrier spacing: indicating the subcarrier spacing of CSI-RS; CSI-RS resource index: indicating the CSI-RS resource number; CSI-RS starting symbol position: indicating the super-start symbol of the CSI-RS time domain; CSI-RS frequency domain position indication: indicating the position of the CSI-RS in the frequency domain; scrambling code ID generated by the CSI-RS sequence; CSI-RS measurement period; CSI-RS measurement bandwidth, indicating which RBs are measured; measurement cell ID. For details, please refer to the relevant information of CSI-RS-ResourceConfigMobility in standard 38.331, which will not be repeated here. In specific implementation, the CSI-RS information used for RRM measurement can be reconfigured, such as changing the subcarrier spacing, changing the CSI-RS starting symbol position, etc.; or, for the existing CSI-RS information used for RRM measurement, only the period used for RRM measurement is changed. At this time, the configuration information used for RRM measurement includes at least CSI-RS index and RRM measurement period.

[0145] The configuration information used for CSI measurement may include, but is not limited to: CSI-RS resource measurement information, CSI feedback cycle. For details, please refer to the CSI-MeasConfig related information in standard 38.331, which will not be repeated here. In specific implementation, the CSI-RS information used for CSI measurement can be reconfigured; or, for the existing CSI-RS information used for CSI measurement, only the CSI-RS resource measurement information and CSI feedback cycle used for CSI measurement are changed. At this time, the configuration information used for CSI measurement includes at least the CSI-RS index, CSI-RS resource measurement information, and CSI feedback cycle.

[0146] Here, the configuration parameters may be requested in a bitmap manner, where a bit may represent a configuration parameter being queried.

[0147] As an example, for the dual connection of the EN-DC architecture, the first network device can request the second device for configuration parameters in the energy-saving working mode, preferably including SSB transmission period and RRM measurement period; in addition, the configuration parameters that can be requested include but are not limited to SSB frequency domain position, RRM measurement resources, CSI measurement resources and measurement period, etc. A 10-bit bitmap can be used to query the configuration parameters. When the query parameter configuration parameters are SSB transmission period and RRM measurement period, the positions corresponding to the SSB transmission period and RRM measurement period in the 10-bit bitmap can be set to "1", and the remaining positions can be set to "0".

[0148] It is worth noting here that, in the request sent by the first network device to the second network device, the configuration parameters of the second network device in the energy-saving working mode may not be inquired.

[0149] 203. The second network device sends a response message of entering the energy-saving working mode to the first network device.

[0150] In this embodiment, the second network device can send a response message to the first network device to accept or refuse to enter the energy-saving working mode based on the current state. The response message can use a 1-bit value. Specifically, when the bit value is "1", it can indicate acceptance to enter the working mode; when the bit value is "0", it can indicate refusal to enter the energy-saving working mode. For example, the second network device is currently transmitting data with the terminal. If entering the energy-saving working mode causes data transmission failure, the second network device can refuse to enter the energy-saving working mode.

[0151] In some possible implementations, when the second network device refuses to enter the energy-saving working mode, a bit stream may be used to indicate a reason value for the refusal. The reason value may, for example, indicate that data transmission is currently in progress.

[0152] When the second network device accepts entering the energy-saving working mode, the response information of the second network device may include at least one of the following: common channel configuration information of the second network device in the energy-saving working mode; configuration information used by the second network device for wireless resource management RRM measurement in the energy-saving working mode; configuration information used by the second network device for channel state information CSI measurement in the energy-saving working mode.

[0153] 204. The first network device sends first indication information for indicating entering a power-saving working mode to a terminal connected to the second network device.

[0154] Specifically, the second network device can manage a secondary cell group (SCG), which may include one or more carriers. When the SCG includes multiple carriers, each SCG can be divided into multiple logical cells, including a primary secondary cell (PScell) and one or more secondary cells (Scell ​​for short). Each logical cell corresponds to a carrier (e.g., a carrier or a carrier formed by carrier aggregation) in the second network device. Among them, the carrier corresponding to the PScell ​​can be called a primary carrier. If the SCG includes only one carrier, the logical cell corresponding to the carrier is the PScell. When the first network device configures the terminal, a mapping relationship between the terminal and the SCG can be established, that is, a terminal can correspond to one or more SCGs. The first network device can instruct the SCG to deactivate, or it can instruct the carrier in the SCG to deactivate. When the carrier in the SCG is instructed to deactivate, the logical cell is instructed to deactivate. Among them, deactivation is also inactive. In the deactivated state, the terminal can measure the second network device, but cannot transmit data with the second network device. Here, data transmission does not include RRM measurement and transmission of common channels.

[0155] When the second network device enters the energy-saving working mode, the first network device may instruct some or all carriers in the second network device to work in a deactivated state. Generally, the more carriers working in the deactivated state, the lower the power consumption of the second network device. The first network device may determine the number of deactivated carriers in the second network device according to the load state, energy consumption, etc. of the second network device.

[0156] Since there are many terminals that perform dual-connection communication with the first network device and the second network device, the first indication information includes the terminal ID, so as to indicate which terminals enter the energy-saving working mode.

[0157] The first indication information also includes an SCG index and a carrier index. Specifically, the SCG index is used to indicate which SCG enters the deactivated state, and the carrier index is used to indicate which carrier in the SCG enters the deactivated state. Among them, both the SCG index and the carrier index can be set in the form of a bitmap. Taking the SCG index as an example, each bit in the bitmap represents an SCG. In the bitmap, when the value representing a certain SCG is "0", it can indicate that the SCG enters the deactivated state; when the value representing a certain SCG is "1", it can indicate that the SCG is in the activated state.

[0158] Optionally, the first network device may set all carriers in the second network device in a deactivated state. Thus, the first indication information may indicate that all carriers in the second network device are operating in a deactivated state.

[0159] Optionally, the first network device may set the PScell ​​in the SCG corresponding to the second network device to a dormant state. At this time, the first indication information may indicate that the PScell ​​in the second network device is operating in a dormant state and that other carriers in the SCG are operating in a deactivated state.

[0160] It is worth noting here that when the carrier in the second network device is set to a sleep state, the terminal needs to perform CSI measurement and reporting on the second network device; when the carrier in the second network device is set to a deactivated state, the terminal does not need to perform CSI measurement and reporting on the second network device.

[0161] The first indication information may further include configuration information used by the second network device for RRM measurement and configuration information used by the second network device for CSI measurement in the energy-saving working mode.

[0162] Optionally, the first network device may send the first indication information to the terminal via MAC CE signaling.

[0163] Alternatively, the first network device may send the first indication information to the terminal via DCI signaling.

[0164] Alternatively, the first network device may send the first indication information to the terminal through RRC signaling.

[0165] 205. The terminal sends second indication information to the first network device.

[0166] In this embodiment, the second indication information is used to indicate that the terminal configuration is completed.

[0167] As an example, when the first network device sends the first indication information to the terminal via MAC CE signaling, the terminal may send the second indication information via MAC CE signaling. Typically, MAC CE signaling is carried via a PDSCH channel, and the terminal may indicate whether the configuration is completed via ACK / NACK.

[0168] As an example, when the first network device sends the first indication information to the terminal through RRC signaling, the terminal can perform various configurations on the first indication information carried by the RRC signaling. When the terminal configuration is completed, the first indication information carried by the RRC signaling can be sent to the first network device to complete the configuration. For example, the "RRCReconfiguration Complete" signaling defined in the existing TS36.331 standard is the signaling that the terminal needs to send to the first network device.

[0169] It should be noted that 205 is not a necessary step. In some other possible implementations, for example, when the first network device sends the first indication information to the terminal through DIC signaling, it is equivalent to instructing the terminal to enter the energy-saving working mode. At this time, the terminal does not need to send the second indication information to the second network device.

[0170] 206: The first network device sends third indication information to the second network device.

[0171] In this embodiment, after receiving the second indication information sent by the terminal and used for indicating that the configuration is completed, the first network device may send the third indication information used for indicating that the terminal configuration is completed to the second network device.

[0172] In a certain scenario, the terminal may be unable to complete the configuration due to some reasons, causing the second network device to enter the energy-saving working mode. The terminal's measurement of the second network device is inaccurate and cannot be synchronized with the second network device (for example, the second network device is still measured using the configuration information in the dual-connection working mode). As a result, when the terminal switches from the energy-saving working mode to the dual-connection working mode, it cannot quickly enter the dual-connection mode due to the lack of synchronization between the terminal and the second network device signal, thereby affecting the information transmission rate between the terminal and the network device. By sending the third indication information to the second network device, the second network device can reserve a certain amount of time to wait for the terminal to configure, thereby improving the success rate of terminal configuration.

[0173] 207: The second network device enters the energy-saving working mode.

[0174] It should be noted that the present application does not limit the order of the steps. When the second network device receives the request sent by the first network device, the second network device can directly enter the energy-saving working mode if it determines that it can enter the energy-saving mode. In other words, the second network device does not need to enter the energy-saving working mode after receiving the third indication information. Alternatively, the second network device can send a response message to the first network device and receive the third indication information from the first network device after entering the energy-saving working mode. At this time, the order of the above steps can be: 201-202-207-203-204-205.

[0175] In addition, step 206 is not a necessary step. In some application scenarios, the first network device may not need to send the third indication information to the second network device.

[0176] Please continue to refer to Figure 3 , which shows a schematic flow chart of another conversion method from the dual connection working mode to the energy-saving working mode provided in an embodiment of the present application. It should be understood that Figure 3The steps or operations of the conversion method from the dual connection working mode to the energy-saving working mode are shown, but these steps or operations are only examples, and the embodiment of the present application can also perform other operations or Figure 2 The deformation of each operation in . Figure 3 As shown, the method for converting from the dual connection working mode to the energy-saving working mode may include steps 301-307.

[0177] Step 301: The second network device determines whether a trigger condition for switching from a dual connection working mode to a power saving working mode is met.

[0178] In this embodiment, the triggering condition for switching from the dual connection working mode to the energy-saving working mode may include one or more of the following:

[0179] The load or resource utilization of the first network device is lower than the first preset threshold value; the load or resource utilization of the second network device is lower than the second preset threshold value; the load or resource utilization of the first network device and the second network device are both lower than the third preset threshold value; the energy consumption of the second network device is higher than the fourth preset threshold value, and the load is lower than the fifth preset threshold value.

[0180] 302. When detecting that a trigger condition for converting the dual connection working mode to the energy-saving working mode is met, the second network device sends a working mode conversion request for converting the dual connection working mode to the energy-saving working mode to the first network device.

[0181] Here, the request to enter the energy-saving working mode may carry at least one of the following information: common channel configuration information of the second network device in the energy-saving working mode; configuration information for wireless resource management RRM measurement of the second network device in the energy-saving working mode; configuration information for channel state information CSI measurement of the second network device in the energy-saving working mode.

[0182] 303. The first network device sends a response message of entering the energy-saving working mode to the second network device.

[0183] After receiving the request sent by the second network device, the first network device can determine whether to allow the second network device to enter the energy-saving working mode according to its current state. Thus, a response message accepting or refusing to enter the energy-saving working mode can be sent to the first network device. The response message can use a 1-bit value.

[0184] 304. The first network device sends first indication information for indicating entering the energy-saving working mode to the terminal connected to the second network device.

[0185] After determining that the second network device can be allowed to enter the energy-saving working mode, the first network device can send first indication information to the terminal connected to the second network device. The specific content of the first indication information can refer to the content of the first indication information shown in 204, which will not be repeated here.

[0186] 305. The terminal sends second indication information to the first network device.

[0187] 306: The first network device sends third indication information to the second network device.

[0188] 307: The second network enters the energy-saving working mode.

[0189] For the specific implementation of 305-307 and the contents of each instruction information, please refer to Figure 2 The detailed description of 205-207 shown will not be repeated here.

[0190] from Figure 3 It can be seen that Figure 2 The embodiment shown differs in that Figure 3 In the embodiment shown, the second network device determines whether the trigger condition for switching from the dual connection mode to the energy-saving mode is met. Thus, the first network device and the second network device can simultaneously monitor the power consumption of the dual connection system, improve the monitoring effect, and help reduce the power consumption of the dual connection system.

[0191] Please continue to refer to Figure 4 , which shows a schematic flow chart of a conversion method from an energy-saving working mode to a dual-connection working mode provided in an embodiment of the present application. Figure 4 As shown, the method for converting from the energy-saving working mode to the dual-connection working mode may include steps 401-407.

[0192] 401. A first network device determines whether a trigger condition for switching from an energy-saving working mode to a dual-connection working mode is met.

[0193] In this embodiment, the triggering condition for switching from the energy-saving working mode to the dual-connection working mode may include one or more of the following:

[0194] The load or resource utilization of the first network device is higher than a preset threshold value; the data transmission rate requested by the terminal is higher than the data transmission rate of the first network device; the energy consumption of the first network is greater than the preset threshold value, and in the dual connection working mode, the sum of the energy consumption of the first network device and the second network device is less than the energy consumption of the first network.

[0195] Specifically, when the load of the first network device is higher than the first preset threshold value, it means that the terminal data transmission volume exceeds the load of the first network device, and the first network device alone cannot bear the data transmission with the terminal. At this time, the second network device can be triggered to enter the dual connection working mode.

[0196] The resources in the above resource utilization rate may include, as an example, but are not limited to, frequency domain resource utilization rate, time domain resource utilization rate, etc. The specific resources included may refer to the description of the resources in 201, which will not be repeated here. When the resource utilization rate of the first network device is higher than the preset threshold value, it means that the terminal data transmission volume exceeds the load of the first network device, and the first network device alone cannot bear the data transmission with the terminal. At this time, the second network device can be triggered to enter the dual connection working mode.

[0197] In a specific application scenario, the current maximum data transmission rate between the first network device and the terminal is 100Mbit / s. The data transmission rate requested by the terminal is 200Mbit / s. Although the load of the first network device is not higher than the preset threshold value at this time, since the maximum data transmission rate of the first network device is less than the data transmission rate requested by the terminal, the second network device can be triggered to enter the dual connection working mode.

[0198] The first network device can estimate the energy consumption of the network device according to the load of the network device. When the first network device estimates that its own power consumption is greater than a preset threshold value, but the second network device enters the dual connection mode, the first network device transfers part of the load to the second network device. At this time, when the total power consumption of the first network device and the second network device is less than the current power consumption of the first network device, the second network device can also be triggered to enter the dual connection working mode.

[0199] 402. When detecting that a trigger condition for converting from the energy-saving working mode to the dual-connection working mode is met, the first network device sends a working mode conversion request for converting from the energy-saving working mode to the dual-connection working mode to the second network device.

[0200] In this embodiment, when the first network device detects that at least one trigger condition shown in 401 is met, the first network device may send a request to enter the dual connection working mode to the first network device.

[0201] In a possible implementation, the first network device may send bit stream data to the second network device to directly instruct the second network device to enter the dual connection working mode.

[0202] In a possible implementation, the first network device may send a request to the second network device in a bitmap manner, and simultaneously use one bit to inquire whether the second network device can enter the dual connection mode.

[0203] In a possible implementation, when the first network device sends a request to the second network device to enter the dual connection mode, it may also include configuration parameters that need to be returned by the second network device. When the second network device enters the dual connection working mode, various parameters need to be reconfigured so that the terminal can quickly access the second network device.

[0204] Specifically, the configuration parameters that the first network device may request the second network device to return include but are not limited to at least one of the following: common channel configuration information of the second network device in dual connection working mode; configuration information of the physical random access channel PRACH of the second network device in dual connection working mode; common channel configuration information of the second network device in dual connection working mode; configuration information of the second network device for radio resource management RRM measurement in dual connection working mode. Here, the configuration parameters may be requested in a bitmap manner, where one bit may represent a configuration parameter being queried.

[0205] It is worth noting here that, in the request sent by the first network device to the second network device, the second network device may not be asked for configuration parameters in the dual connection working mode.

[0206] 403. The second network device sends a response message of entering the dual connection working mode to the first network device.

[0207] In this embodiment, the second network device may send a response message to the first network device to accept or refuse to enter the dual connection working mode based on the current state. The response message may use a 1-bit value. Specifically, when the bit value is "1", it may indicate acceptance of entering the working mode; when the bit value is "0", it may indicate refusal to enter the dual connection working mode.

[0208] In some possible implementations, when the second network device refuses to enter the dual-connectivity working mode, a reason value for the refusal may also be indicated by using a bit stream.

[0209] When the second network device accepts entering the dual connection working mode, the response information of the second network device may include at least one of the following: configuration information of the physical random access channel PRACH of the second network device in the dual connection working mode; configuration information of the common channel of the second network device in the dual connection working mode; configuration information of the second network device for radio resource management RRM measurement in the said working mode.

[0210] 404. The first network device sends first indication information for indicating entering a power-saving working mode to a terminal connected to the second network device.

[0211] When the second network device is in the energy-saving working mode, some or all carriers in the second network device work in a deactivated state. When the second network device is converted from the energy-saving working mode to the dual-connection working mode, the carriers of the second network device need to be activated so that each carrier works in an activated state.

[0212] The first network device may record the terminal IDs connected to the second network device, so that the terminals may be informed of which terminals are converted from the energy-saving working mode to the dual-connection working mode through the terminal IDs.

[0213] Thus, the first indication information may include the terminal ID, the SCG index of the second network device, and the carrier index. Specifically, the SCG index is used to indicate which SCG enters the activated state, and the carrier index is used to indicate which carriers in the SCG enter the activated state. Among them, the SCG index and the carrier index can be set in a bitmap manner.

[0214] Optionally, the first network device can learn from the response information received from the second network device whether the configuration information and common channel period used for RRM measurement by the second network device have changed when switching from the energy-saving working mode to the dual-connection working mode. When the first network device determines that the configuration information and common channel period used for RRM measurement have changed, the first indication information also needs to include the configuration information and common channel period used for RRM measurement by the second network device.

[0215] 405. The terminal sends second indication information to the first network device.

[0216] In this embodiment, the second indication information is used to indicate that the terminal configuration is completed.

[0217] The specific implementation of this step can refer to Figure 2 The description of 205 shown is not repeated here.

[0218] It should be noted that 405 is not a necessary step. In some possible implementations, for example, when the first network device sends the first indication information to the terminal through DIC signaling, it is equivalent to instructing the terminal to enter the dual connection working mode. At this time, the terminal does not need to send the second indication information to the second network device.

[0219] 406: The terminal sends a random access request to the second network device.

[0220] In this embodiment, after receiving the first indication information from the first network device, the terminal can configure various parameters based on the first indication information. Therefore, after completing the configuration of various parameters, the terminal can send a random access request to the second network device.

[0221] 407: The second network device determines that the terminal random access is successful and enters a dual connection working mode.

[0222] In this embodiment, after determining that the random access of the terminal is successful, the second network device may determine that the dual connection working mode has been entered, and data transmission may be performed with the terminal at this time.

[0223] It should be understood that Figure 4 The steps or operations of the conversion method from the energy-saving working mode to the dual-connection working mode are shown, but these steps or operations are only examples, and the embodiment of the present application may also perform other operations or Figure 4 In addition, Figure 4 The steps in Figure 4 are executed in a different order than the ones presented, and may not be executed Figure 4 For example, when the terminal receives the first indication information sent by the first network device, it is not necessary to send the second indication information to the first network device, and directly send the random access request to the second network device. At this time, 405 is not a step that must be performed.

[0224] from Figure 2-Figure 4 It can be seen from the illustrated embodiment that in the process of converting the second network device from the energy-saving working mode to the dual-connection working mode, or from the dual-connection working mode to the energy-saving working mode, each time the working conversion is performed, the second network device needs to exchange public information, RRM measurement and other configuration information with the first network device and the terminal.

[0225] Please continue to refer to Figure 5 , which shows a schematic flow chart of a parameter preconfiguration method for an energy-saving working mode provided in an embodiment of the present application. Before the second network device enters the energy-saving working mode for the first time, the parameters of the energy-saving working mode can be preconfigured. Therefore, the second network device does not need to exchange configuration information such as RRM measurement with the first network device every time during the subsequent mode conversion project, thereby further reducing the signaling overhead. Figure 5 , the parameter preconfiguration method of the energy-saving working mode is described in detail.

[0226] 501. The second network device sends configuration information in the energy-saving working mode to the first network device.

[0227] In this embodiment, the configuration information of the second network device in the energy-saving working mode may include one or more groups of configuration parameters. Each group of configuration parameters includes a configuration identifier corresponding to the group of configuration parameters, which may also be referred to as a configuration index. Each group of configuration parameters also includes at least one of the following: common channel configuration information, configuration information for radio resource management RRM measurement, and configuration information for channel state information CSI measurement.

[0228] Specifically, when the configuration information includes multiple groups of configuration parameters, each group of configuration parameters is different. That is to say, the common channel configuration information, RRM measurement configuration information, and CSI measurement configuration information of configuration identifier 1 are different from the common channel configuration information, RRM measurement configuration information, and CSI measurement configuration information of configuration identifier 2. Generally, the longer the configuration parameters such as the RRM measurement period and the common channel transmission period are, the greater the energy saving gain. Therefore, when the second network is set to enter the energy-saving working mode, it can select a group of configuration parameters with the longest period from the above multiple groups of configuration parameters.

[0229] In some scenarios, the terminal cannot keep in sync with the second network device or cannot measure the second network device within a certain period of time due to the long RRM measurement period and the common channel transmission period. At this time, the terminal usually triggers a request to delete the second network device. After receiving the request, the second network device can reselect a set of configuration parameters and send them to the first network device, so that the first network device can send the new configuration parameters to the terminal.

[0230] In order to facilitate subsequent terminals to maintain RRM measurement and synchronization signal detection on the second network device when the second network device enters the energy-saving mode, the second network device needs to send each set of configuration parameters to the first network device when pre-configuring the energy-saving working mode.

[0231] 502. The first network device sends configuration information of the second network device in the energy-saving working mode to the terminal.

[0232] After receiving the configuration information in the energy-saving working mode sent by the second network device, the first network device can send the configuration information to the terminal, so that the terminal configures different configuration parameters when the second network device enters the energy-saving working mode.

[0233] Optionally, the first network device may send the pre-configuration information through RRC signaling; or, the first network device may send the pre-configuration information through MAC CE signaling; or, the first network device may send the pre-configuration information through DCI signaling.

[0234] Optionally, before or after this step, the first network device may also send a response message to the second network device. Thus, the second network device may determine whether the first network device has received the configuration of the second network device in the energy-saving working mode. At the same time, in the response message sent by the first network device to the second network device, 1 bit may be used to indicate whether the configuration request of the second network device is accepted. When indicating that the configuration request of the second network device is rejected, multiple bits may also be used to indicate the reason value for rejection.

[0235] Optionally, after receiving the configuration information of the second network device in the energy-saving working mode sent by the first network, the terminal can perform configuration based on the configuration information. After the configuration is completed, an indication message of configuration completion can be sent to the first network device. As an example, when the first network device sends the first indication message to the terminal through RRC signaling, the terminal can send information indicating the completion of configuration to the first network device through RRC signaling. When the first network device sends the first indication message to the terminal through MAC CE signaling, the terminal can send information indicating the completion of configuration to the first network device through MAC CE signaling. When the first network device sends the first indication message to the terminal through DCI signaling, the terminal may not need to send the indication message of configuration completion to the first network device.

[0236] based on Figure 5 The pre-configuration of the second network device information in the energy-saving working mode is further combined with Figure 2 , a conversion method for converting from a dual connection working mode to an energy-saving working mode is further described.

[0237] Here, after the energy-saving working mode is preconfigured, the conversion steps from the dual connection working mode to the energy-saving working mode are the same as Figure 2 The interaction steps between the devices shown are the same, except that the contents of the request information, response information, and indication information sent by each device are different.

[0238] Among them, Figure 2 In the illustrated 202, when the first network device sends a request to the second network device to enter the energy-saving working mode, in addition to requesting the second network device to enter the energy-saving working mode, it can carry a configuration identifier for inquiring the configuration parameters used by the second network device in the energy-saving working mode. That is to say, since the configuration parameters have previously completed the configuration of common channel configuration information, RRM measurement configuration information, CSI measurement configuration information, etc., the first network device does not need to inquire about parameters such as common channel configuration information, RRM measurement configuration information, CSI measurement configuration information, etc., thereby reducing signaling overhead.

[0239] exist Figure 2In 203 shown, the response information sent by the second network device to the first network device includes, in addition to indicating whether the energy-saving working mode can be entered, a configuration identifier of the configuration parameters adopted when entering the energy-saving working mode. Specifically, the second network device can use a bitmap to indicate the configuration identifier of the configuration parameters adopted. Assuming that the second network device is pre-configured with 5 groups of configuration parameters, a 5-bit bitmap indication can be used, the first bit is used to indicate configuration identifier 1, the second bit is used to indicate configuration identifier 2, the third bit is used to indicate configuration identifier 3, the fourth bit is used to indicate configuration identifier 4, and the fifth bit is used to indicate configuration identifier 5. In each bit, "0" represents that the configuration parameters corresponding to the configuration identifier are not adopted, and "1" represents that the configuration parameters corresponding to the configuration identifier are adopted. When the second network device adopts the configuration parameters corresponding to configuration identifier 2, the bitmap can be set to "01000" to indicate that configuration identifier 2 is used for configuration parameters.

[0240] exist Figure 2 In the shown 204, the first indication information sent by the first network device to the terminal to indicate entering the energy-saving working mode, in addition to including one or more of the status information of the cells in the cell set SCG of the second network device in the energy-saving working mode and the status information of the carrier of the second network device in the energy-saving working mode, also includes a configuration identifier corresponding to the configuration parameters used to indicate the second network device entering the energy-saving working mode.

[0241] based on Figure 5 The pre-configuration of the second network device information in the energy-saving working mode is further combined with Figure 3 , another conversion method from the dual connection working mode to the energy-saving working mode is further described.

[0242] Here, after the energy-saving working mode is preconfigured, the conversion steps from the dual connection working mode to the energy-saving working mode are the same as Figure 3 The interaction steps between the devices shown are the same, except that the contents of the request information, response information, and indication information sent by each device are different.

[0243] Among them, Figure 3 In 302 shown, when the second network device sends a request to the first network device to enter the energy-saving working mode, in addition to requesting the second network device to enter the energy-saving working mode, it can also carry a configuration identifier of the configuration parameters used by the second network device in the energy-saving working mode.

[0244] exist Figure 3In the shown 304, the first indication information sent by the first network device to the terminal to indicate entering the energy-saving working mode, in addition to including one or more of the status information of the cells in the cell set SCG of the second network device in the energy-saving working mode and the status information of the carrier of the second network device in the energy-saving working mode, also includes a configuration identifier corresponding to the configuration parameters used to indicate the second network device entering the energy-saving working mode.

[0245] based on Figure 5 The pre-configuration of the second network device information in the energy-saving working mode is further combined with Figure 4 , a conversion method from the energy-saving working mode to the dual-connection working mode is further described.

[0246] Here, after the energy-saving working mode is preconfigured, the conversion steps from the energy-saving working mode to the dual connection working mode are the same as Figure 4 The interaction steps between the devices shown are the same, except that the contents of the request information, response information, and indication information sent by each device are different.

[0247] Among them, Figure 4 In the illustrated 402, when the first network device sends a request to the second network device to enter the dual connection working mode, in addition to requesting the second network device to enter the dual connection working mode, it can carry a configuration identifier corresponding to the configuration parameters to be canceled when the second network device enters the dual connection working mode. Here, the first network device, the second network device and the terminal can agree on the configuration parameters in the dual connection working mode. By canceling the configuration identifier corresponding to the configuration parameters adopted by the second network device in the energy-saving working mode, parameters such as common channel configuration information, RRM measurement configuration information, CSI measurement configuration information, etc. can be reset, that is, it is considered that the configuration parameters in the dual connection working mode are adopted, so that the first network device can no longer inquire about the configuration parameters in the dual connection working mode, thereby reducing signaling expenses.

[0248] exist Figure 4 In 403 shown, the response information sent by the second network device to the first network device includes, in addition to indicating whether the dual connection working mode can be entered, the configuration identifier to be canceled. Specifically, the second network device can use a bitmap to indicate the configuration identifier corresponding to the canceled configuration parameter. Assuming that the second network device is pre-configured with 5 groups of configuration parameters, when the second network device adopts the configuration parameters corresponding to configuration identifier 2 in the energy-saving working state, the bitmap can be set to "00000", thereby indicating the cancellation of the configuration parameters corresponding to configuration identifier 2.

[0249] exist Figure 4In the shown 404, the first indication information sent by the first network device to the terminal to indicate entering the energy-saving working mode, in addition to including one or more of the status information of the cells in the cell set SCG of the second network device in the energy-saving working mode and the status information of the carrier of the second network device in the energy-saving working mode, also includes a configuration identifier corresponding to the configuration parameters to be canceled when the second network device enters the dual connection working mode.
