Description

Working mode conversion method and device of dual-connection network equipment Technical Field
The present application relates to the field of communications, and more particularly, to a method and apparatus for operating mode transition of a dual connectivity network device in the field of communications.
Background
With the development of scientific technology, the communication technology is dramatically improved. Through long-term evolution and development of wireless communication technologies, in the current wireless communication technology, in order to improve the information transmission rate, a main network device and an auxiliary network device are generally deployed in the same area range, and a terminal device can support simultaneous access to the main network device and the auxiliary network device, so that data transmission can be performed with the main network device and the auxiliary network device at the same time. The randomness of the amount of communication data results in randomness of the amount of load of the network device. When the communication data volume is small, the data transmission rate can be met by adopting the main network equipment. Since the network device has a large static power consumption (i.e. internal energy loss during idle operation of the network device, such as operating power loss of modules such as power amplifier, intermediate frequency, radio frequency, etc.), in order to reduce the power consumption of the secondary network device, some hardware modules of the secondary network device are usually required to be turned off.
In the related art, when the load capacity of the auxiliary network device is smaller than a preset threshold, the auxiliary network device is turned off to reduce the power consumption of the auxiliary network device; when the load capacity of the main network device is larger than the preset threshold value or the mobile device with high transmission rate requirement accesses, the auxiliary network device needs to be restarted. The random data transmission amount may cause the load of the primary and secondary network devices to be too high or too low, which may result in repeated shutdown operations of the secondary network devices. Each time the auxiliary network device is turned off or turned on, the terminal is required to reconfigure parameters of the auxiliary network device to be accessed, which results in data transmission delay. Therefore, on one hand, the closing time of the auxiliary network equipment is reduced, and the user experience is reduced; on the other hand, when the delay is too large, the delay requirement cannot be met even if double connection is opened, and the energy of the auxiliary network equipment is wasted. Secondly, after the auxiliary network device is closed, the terminal cannot detect the auxiliary network device information. When the dual connectivity is to be opened, in order to obtain the best matching secondary network device, the terminal device needs to perform secondary access (i.e., to search synchronization information of the secondary network device again, read system information again, perform regional measurement and report again, etc.), which seriously results in data delay; in order to avoid the secondary access of the terminal device, the main network device randomly adds the auxiliary network device, which causes that the auxiliary network device added by the main network device cannot meet the higher data transmission speed and also affects the data transmission rate.

The network devices (the first network device and the second network device) in this embodiment may be devices for communicating with a terminal device, where the network devices may also be referred to as access network devices or radio access network devices, and may be evolved node bs (enbs) or eNodeB in an LTE system, and may also be wireless controllers in a Cloud Radio Access Network (CRAN) scenario, or the access devices may be relay stations, access points, vehicle-mounted devices, wearable devices, and access devices in a future 5G network or access devices in a future evolved PLMN network, and may also be Access Points (APs) in a WLAN, and may be gnbs in a new radio system (NR) system.
In addition, in this embodiment of the present application, the Network devices (the first Network device and the second Network device) may also be devices in a RAN (Radio Access Network), or RAN nodes that Access the terminal device to a wireless Network. For example, by way of example and not limitation, network devices may be enumerated: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc.
An access device provides service for a cell, and a terminal device communicates with the access device through a transmission resource (e.g., a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the access device (e.g., a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell), where the small cell may include: urban cell (metro cell), micro cell (microcell), pico cell (pico cell), femto cell (femto cell), etc., and these small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.

For example, in a Carrier Aggregation (CA) scenario, when a secondary carrier is configured for a terminal device, a carrier index of the secondary carrier and a Cell identification (Cell ID) of a secondary Cell operating on the secondary carrier are carried at the same time, and in this case, it may be considered that the concepts of the carrier and the Cell are equivalent, for example, it is equivalent that the terminal device accesses one carrier and one Cell.
Referring to fig. 1a, fig. 1a is a schematic diagram illustrating a network architecture applied to an embodiment of the present application. In fig. 1a, a terminal device can access two network devices simultaneously, and this access manner is called dual-connectivity (DC). Among the two network devices, the first network device, which is responsible for exchanging the radio resource control message with the terminal device and is responsible for exchanging with the core network control plane entity, may also be referred to as a primary network device, and the other network device, which is responsible for exchanging with the core network control plane entity, may also be referred to as a secondary network device.
Similarly, a terminal device may also have a communication connection with multiple access devices and may transmit and receive data, which may be referred to as a multi-connection or multi-link (MC), where one of the multiple access devices may be responsible for interacting with the terminal device for radio resource control messages and for interacting with a core network control plane entity, and then this network device may be referred to as a primary network device, and the rest of the network devices may be referred to as secondary network devices.
In this embodiment, the first network device and the second network device may be network devices of the same radio 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 radio 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 the NR system, and the secondary network device is a network device of the LTE system. The main network device and the auxiliary network device can communicate with each other through the interface, so that the main network device can acquire various information of the auxiliary network device. This information may include, for example, but is not limited to, the load capacity of the secondary network device, resource utilization, and the like. Likewise, the secondary network device may also learn information such as load capacity, resource utilization, etc. of the primary network device.
The following briefly introduces 3 specific multiple radio access type dual connectivity (MR-DC) architectures applicable to the present application:
1) E-UTRA NR DC (EN-DC for short) architecture
This architecture may also be referred to as selection 3 series. Under this architecture, an LTE network device (such as an LTE eNB) performs DC as a primary network device, an NR network device (such as a gNB) performs DC as a secondary network device, and a core network device is an EPC. The LTE eNB is connected to the EPC through an S1-C interface or an S1-U interface, and air interface transmission resources are provided for data between the terminal equipment and the EPC. Or the LTE eNB is connected to the EPC through an S1-C interface or an S1-U interface, and the gNB is connected to the EPC through an S1-U interface, so that air interface transmission resources are provided for data transmission between the terminal equipment and the EPC.
2) NR E-UTRA DC (NE-DC for short) architecture
This architecture may also be referred to as option 4 series. Under this architecture, NR network devices (such as a gNB) perform DC as primary network devices, LTE network devices (such as ng enbs) perform DC as secondary network devices, and core network devices are 5 GCs. The gNB is connected to the 5GC through an NG-C interface or an NG-U interface, and air interface transmission resources are provided for data transmission between the terminal equipment and the 5 GC; or, the gNB is connected to the 5GC through an NG-C interface or an NG-U interface, and the NG-eNB is connected to the 5GC through an NG-U interface, so that air interface transmission resources are provided for data transmission between the terminal equipment and the 5 GC.
3) Next Generation E-UTRA NR DC (NG NE-DC for short) architecture
This architecture may also be referred to as the option 7 series. Namely, the LTE network device (such as ng-gbb) performs DC as a primary network device, the NR network device (such as gbb) performs DC as a secondary network device, and the core network device is 5 GC. The NG-eNB is connected to the 5GC through an NG-C interface or an NG-U interface, and air interface transmission resources are provided for data transmission between the terminal equipment and the 5 GC; or the NG-eNB is connected to the 5GC through an NG-C interface or an NG-U interface, and the gNB is connected to the 5GC through an NG-U interface, so that air interface transmission resources are provided for data transmission between the terminal equipment and the 5 GC.
In one possible implementation, the first network device and the second network device may be access network devices deployed on different sites. In fig. 1a, a situation is shown where a first network device and a second network device are located at different sites. At this time, each network device includes a processor and a transceiver to receive various signals from or transmit signals to the terminal and process the signals. As shown in fig. 1b, fig. 1b is a schematic diagram illustrating an internal structure of a first network device and a second network device and a terminal deployed on different sites. As can be seen from fig. 1b, the first network device communicates with the terminal via the transceiver 1; the second network device communicates with the terminal through the transceiver 2; the terminal can communicate with the first network device and the second network device simultaneously via the transceiver 3.
In another possible implementation manner, the first network device and the second network device may also be network devices deployed on the same site. As shown in fig. 1c, fig. 1c is a schematic diagram illustrating another network architecture applied to the embodiment of the present application. In fig. 1c, a situation is shown where the first network device and the second network device are provided at the same site. At this time, the first network device and the second network device may share the same transceiver to communicate with the terminal. As shown in fig. 1d, fig. 1d is a schematic diagram illustrating an internal structure of a first network device and a second network device, which are deployed on the same site, and a terminal. As can be seen from fig. 1d, the first network device comprises a processor 1 and the second network device comprises a processor 2. And both share a transceiver 3. That is, both the first network device and the second network device communicate with the terminal through the transceiver 3.
In the network devices shown in fig. 1a to 1d, the first network device and the second network device are not fixed, that is, in some cases (for example, the second network device is responsible for exchanging radio resource control messages with the terminal device), the second network device may be used as a primary network device, and the first network device may be used as a secondary network device. And is not particularly limited herein.
In the network devices shown in fig. 1 a-1 d, the secondary network device may have two operating modes, a first operating mode and a second operating mode. In the first operating mode, the secondary network device communicates with the terminal and performs data transmission, which is also referred to as a non-energy-saving operating mode. Here, the non-power saving operation mode may include a multi-connection operation mode, a dual-connection operation mode, and the like. In the second operation mode, the secondary network device does not perform data transmission with the terminal, which is also referred to as an energy saving operation mode. For the sake of more clear discussion of the present application, in the following embodiments, the first operation mode is referred to as a dual connection operation mode, and the second operation mode is referred to as an energy saving operation mode, so as to describe the present application in detail. It should be noted that the first operating mode and the second operating mode in this application may also be named by other names, and as long as the operating modes according to the first operating mode and the second operating mode are all within the scope of the first operating mode and the second operating mode shown in this application.
In the dual connectivity mode of operation, the network device has a higher power consumption. When the load capacity of the network device is low, it is not necessary to transmit data to the terminal through the dual connection, and only when the load capacity is sufficiently borne by the main network device, the auxiliary network device may be idle or the load capacity is lower than a preset value. At this time, devices in the auxiliary network device, such as the power amplifier, the radio frequency unit, and the like, still have large static power consumption, so that the power consumption of the auxiliary network device is not reduced due to the reduction of the low load amount. If the device with excessive static power consumption is closed when the auxiliary network equipment is in no-load, the auxiliary network equipment needs to delete the configuration information of the terminal connected with the auxiliary network equipment; when the secondary network device is turned on to restore the dual connectivity to the terminal, the secondary network device needs to newly add the configuration information of the terminal accessing the secondary network device. Thus, when the terminal accesses the auxiliary network device to recover the dual connectivity, the time delay is serious. For example, the delay typically amounts to a hundred milliseconds or more. In a specific application scenario, when a user needs high-speed network downloading, due to the fact that time delay of a terminal accessing an auxiliary network device is serious, data downloading speed of the user is greatly reduced, and user experience is reduced.
In the dual-connection operating mode, the terminal can simultaneously perform data transmission with the primary network device and the secondary network device, so as to improve the data transmission rate of the terminal network. In the energy-saving operating mode, the auxiliary network device periodically turns off or turns on a hardware module with higher static power consumption, such as a middle radio frequency device, in the auxiliary network device, so as to achieve the purpose of reducing power consumption of the auxiliary network device. Meanwhile, in the energy-saving operating mode, the secondary network device transmits a Radio Resource Management (RRM) measurement reference signal and a synchronization signal/broadcast channel (SS/PBCH block, SSB) at a period greater than that of the dual-connection operating mode. At this time, the terminal cannot perform data transmission with the secondary network device, but may perform measurement on the secondary network device to keep synchronization with the secondary network device.
According to the method and the device, when the load is low, the auxiliary network equipment enters the energy-saving mode, the terminal configuration information stored in the auxiliary network equipment is not released, the auxiliary network equipment can be quickly connected with the auxiliary network equipment when the double-connection mode is recovered, the data transmission rate of the terminal is improved, and the user experience is further improved.
In the diagrams shown in fig. 1a to 1d, the first network device (i.e., the primary network device) is illustrated as an LTE network device, and the second network device (i.e., the secondary network device) is illustrated as an NR network device. The present application is not so limited. Combinations of other types of network devices are also possible.
In the following, with reference to fig. 2 to fig. 5, a description will be given by taking the first network device as a primary network device and the second network device as a secondary network device as an example.
Fig. 2 is a schematic flow chart illustrating a method for switching from a dual-connection operating mode to an energy-saving operating mode according to an embodiment of the present application. It should be understood that fig. 2 shows steps or operations of a conversion method from the dual connection operation mode to the power saving operation mode, but the steps or operations are only examples, and other operations or variations of the operations in fig. 2 may be performed by the embodiment of the present application. As shown in fig. 2, the method for converting from the dual connection operation mode to the energy saving operation mode may include steps 201 and 207.
201. The first network device determines whether a trigger condition for a transition from a dual connectivity mode of operation to an energy saving mode of operation is satisfied.
In this embodiment, the trigger condition for switching from the dual connection operating mode to the energy saving operating mode may include one or more of the following:
the load capacity or the resource utilization rate of the first network equipment is lower than a first preset threshold value; the load capacity or the resource utilization rate of the second network equipment is lower than a second preset threshold value; the load capacity or the resource utilization rate of the first network equipment and the second network equipment 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 amount is lower than a fifth preset threshold value.
Specifically, the load amount of the first network device or the load amount of the second network device may be regarded as the communication data transfer amount with the terminal. When the load amount of the first network device is lower than a first preset threshold value, or the load amount of the second network device is detected to be lower than a second preset threshold value, or the load amounts of the first network device and the second network device are detected to be lower than a third preset threshold value, it is indicated that the data transmission amount of the terminal is low, the data transmission with the terminal can be sufficiently undertaken only through the first network device, and the data transmission rate is not smaller than the preset threshold value. At this time, the second network device may be triggered to enter the energy saving mode of operation.
The resources in the resource utilization may include, but are not limited to: the resource allocated or reserved for the terminal device, the user plane connection dedicated to the terminal device between the core networks, and the like, which are not specifically limited in this embodiment of the present application. The resource allocated or reserved for the terminal device may be, for example, an air interface transmission resource, an NG-U interface transmission resource, and the like. The user plane connection dedicated to the terminal device and the core network may include, for example, at least one of transport layer information (transport layer information), a data transmission channel, NG-U transport layer address information allocated to the terminal device, and NG-U transport layer address information allocated to the terminal device by the core network.
The resource utilization rates of the first network device and the second network device may further include frequency domain resource utilization rate and time domain resource utilization rate. The time domain resource may be one or more symbols, one or more slots, one or more mini-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 partial Bandwidths (BWPs).
When the resource utilization rate of the first network device is lower than a first preset threshold, the resource utilization rate of the second network device is lower than a second preset threshold, and the resource utilization rates of the first network device and the second network device are lower than a third preset threshold, it is indicated that the data transmission amount of the terminal is low, the data transmission with the terminal is sufficiently undertaken only through the first network device, and the data transmission rate is not less than the preset threshold. At this time, the second network device may be triggered to enter the energy saving mode of operation.
202. When detecting that a trigger condition for converting the dual-connection working mode into the energy-saving working mode is met, the first network device sends a working mode conversion request for converting the dual-connection working mode into the energy-saving working mode to the second network device.
In this embodiment, the first network device may send a request to enter the energy-saving operating mode to the first network device when detecting that at least one trigger condition shown in 201 is satisfied.
In one possible implementation, the first network device may send bitstream data to the second network device directly instructing the second network device to enter the power saving mode.
In a possible implementation manner, the first network device may send a request to the second network device in a bitmap (bitmap) manner, and meanwhile, a bit is used 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 amount or the resource utilization rate of the second network device is lower than a certain threshold, there may be a case that data transmission has not been completed between the second network device and a certain terminal. When entering the power saving mode, the data transmission with the terminal is usually failed. The first network device requests the second network device to enter the energy-saving mode by adopting an inquiry mode, and can enter the energy-saving mode after the data transmission of the second network device is finished, so that the data transmission failure is avoided.
In a possible implementation manner, when the first network device sends the request for entering the energy saving mode to the second network device, the configuration parameter that needs to be returned by the second network device may also be included. When the second network device enters the power saving mode of operation, various parameters need to be reconfigured. Therefore, the terminal realizes the synchronization with the second network equipment based on the configuration parameters in the energy-saving working mode. 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: the second network equipment configures the information in the common channel in the energy-saving working mode; the second network equipment is used for configuring information of Radio Resource Management (RRM) measurement in an energy-saving working mode; the second network device is configured for channel state information, CSI, measurement in a power saving mode of operation.
The common channel configuration information includes, but is not limited to, a transmission period of a synchronization signal carried by the common channel and a system message.
The information for RRM measurement includes resource index for channel state information reference signal, CSI-RS, measurement period, measurement bandwidth, etc., including but not limited to: subcarrier spacing: indicating a subcarrier spacing of the CSI-RS; CSI-RS resource index: indicating a CSI-RS resource number; CSI-RS start symbol position: a start-of-sequence symbol indicating a CSI-RS time domain; CSI-RS frequency domain position indication: indicating a location of a frequency domain of the CSI-RS; scrambling code ID generated by the CSI-RS sequence; a CSI-RS measurement period; a CSI-RS measurement bandwidth indicating on which RBs to measure; the cell ID is measured. Reference may be made to the relevant information of CSI-RS-ResourceConfigMobility in standard 38.331, which is not described herein again. In specific implementation, the CSI-RS information for RRM measurement may be reconfigured, for example, the subcarrier spacing is changed, the CSI-RS start symbol position is changed, etc.; or only changing the period for RRM measurement aiming at the existing CSI-RS information for RRM measurement, wherein at least a CSI-RS index and an RRM measurement period are included in the configuration information for RRM measurement.
Configuration information for CSI measurement may include, but is not limited to: CSI-RS resource measurement information and a CSI feedback period. Reference may be made to CSI-MeasConfig related information in standard 38.331, which is not described herein again. In specific implementation, the CSI-RS information used for CSI measurement can be reconfigured; or, for the existing CSI-RS information for CSI measurement, only changing the CSI-RS resource measurement information for CSI measurement and the feedback cycle of CSI, where the configuration information for CSI measurement at this time at least includes the CSI-RS index, the CSI-RS resource measurement information, and the feedback cycle of CSI.
Here, the configuration parameters may be requested in a bitmap manner, wherein one bit may represent one configuration parameter being queried.
As an example, for dual connectivity of the EN-DC architecture, the first network device may request the second device for configuration parameters of the second device in the energy saving operating mode, which preferably include an SSB transmission period, an RRM measurement period; in addition, the configuration parameters that can be requested also include, but are not limited to, SSB frequency domain location, RRM measurement resource, CSI measurement resource, measurement period, and the like. The configuration parameters may be queried by using a 10-bit bitmap, and when the configuration parameters are the SSB transmission period and the RRM measurement period, the positions "1" and "0" corresponding to the SSB transmission period and the RRM measurement period in the 10-bit bitmap may be used.
It should be noted here that the first network device may not ask the second network device for configuration parameters in the energy saving operation mode in the request sent to the second network device by the first network device.
203, the second network device sends a response message to the first network device to enter the energy saving mode of operation.
In this embodiment, the second network device may send a response message accepting to enter the energy saving operating mode or rejecting to enter the energy saving operating mode to the first network device based on the current state. The response information may take the form of a 1-bit value. Specifically, when the bit value is "1", it may indicate that the entry into the operating mode is accepted; when the bit value is "0", it may indicate that entry into the power saving operation mode is rejected. For example, when data transmission is currently performed between the second network device and the terminal, if the data transmission fails when the energy saving operating mode is entered, the second network device may refuse to enter the energy saving operating mode.
In some possible implementations, when the second network device rejects entering the power saving operating mode, the cause value of the rejection may also be indicated using a bitstream. The cause value may for example indicate that a data transmission is currently ongoing, etc.
When the second network device is accepting to enter the energy-saving operation mode, the response information of the second network device may include at least one of: the second network equipment configures the information in the common channel in the energy-saving working mode; the second network equipment is used for configuring information of Radio Resource Management (RRM) measurement in an energy-saving working mode; the second network device is configured for channel state information, CSI, measurement in a power saving mode of operation.
And 204, the first network equipment sends first indication information for indicating to enter the energy-saving working mode to a terminal connected with the second network equipment.
Specifically, the second network device may manage a Secondary Cell Group (SCG), and the SCG may include 1 or more carriers. When multiple carriers are included in an SCG, each SCG may be divided into multiple logical cells including a Primary Secondary Cell (PScell) and one or more Secondary cells (scells). Each logical cell corresponds to a carrier (e.g., one carrier, or a carrier formed by carrier aggregation) in the second network device. Among them, the carrier corresponding to the PScell may be referred to as a primary carrier. If the SCG only contains 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 SCGs may be established, that is, one terminal may correspond to one or more SCGs. The first network device may instruct SCG to deactivate, and may also instruct carrier deactivation in SCG. When the carrier in the SCG is indicated to be deactivated, that is, the logical cell is indicated to be deactivated. Wherein deactivation is also inactive. In the deactivated state, the terminal may perform measurement on the second network device, but cannot perform data transmission with the second network device. Here, the data transmission does not include RRM measurement and transmission of a common channel.
When the second network device enters the energy-saving operation mode, the first network device may indicate that part of or all of the carriers in the second network device operate in a deactivated state. Generally, the greater the number of carriers operating in the deactivated state, the less 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 a load state and an energy consumption of the second network device.
Since there are many terminals in dual-connection communication with the first network device and the second network device, the first indication information includes a terminal ID, so that which terminals enter the energy-saving operating mode can be indicated.
The first indication information further 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. Wherein, both the SCG index and the carrier index can be set in a bitmap manner. 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 a deactivated state; when the value representing a certain SCG is "1", it can indicate that the SCG is in an active state.
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 the carriers in the second network device are all operating in the deactivated state.
Optionally, the first network device may set a PScell in an 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 operates in the dormant state, and indicate that other carriers in the SCG operate in the deactivated state.
It should be noted that, when the carrier in the second network device is set to be in the dormant state, the terminal needs to perform CSI measurement and report on the second network device; when the carrier in the second network device is set to be in the deactivated state, the terminal does not need to perform CSI measurement and report on the second network device.
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 operation mode.
Optionally, the first network device may send the first indication information to the terminal through MAC CE signaling.
Alternatively, the first network device may transmit the first indication information to the terminal through DCI signaling.
Alternatively, the first network device may send the first indication information to the terminal through RRC signaling.
205, the terminal sends the second indication information to the first network device.
In this embodiment, the second indication information is used to indicate that the terminal configuration is completed.
As an example, when the first network device transmits the first indication information to the terminal through MAC CE signaling, the terminal may transmit the second indication information through MAC CE signaling. Generally, MAC CE signaling is carried through a PDSCH channel, and a terminal may indicate whether configuration is completed through ACK/NACK.
As an example, when the first network device sends the first indication information to the terminal through RRC signaling, the terminal may perform various configurations on the first indication information carried by the RRC signaling. After the terminal completes configuration, the terminal may send the first indication information carried by the RRC signaling to the first network device. For example, the "rrcrconfiguration Complete" signaling defined in the existing TS36.331 standard is signaling that the terminal needs to send to the first network device.
It is noted that 205 is not a required step. In some other possible implementations, for example, when the first network device sends the first indication information to the terminal through the DIC signaling, it is equivalent to instruct the terminal to enter the power saving operating mode. At this time, the terminal does not need to transmit the second indication information to the second network device.
206: and the first network equipment sends the third indication information to the second network equipment.
In this embodiment, after receiving the second indication information for indicating that the configuration is completed, the first network device may send, to the second network device, third indication information for indicating that the configuration of the terminal is completed.
In a certain scenario, when the terminal may not complete the configuration for some reason and the second network device enters the energy-saving operating mode, the terminal may measure the second network device inaccurately so that the terminal cannot synchronize with the second network device (for example, the terminal still measures the second network device by using the configuration information in the dual-connection operating mode). Therefore, when the terminal is switched from the energy-saving working mode to the dual-connection working mode, the terminal and the second network device cannot enter the dual-connection mode quickly due to asynchronous signals, and the information transmission rate between the terminal and the network device is further influenced. And the third indication information is sent to the second network equipment, so that the second network equipment can reserve a certain time to wait for the terminal to be configured, and the success rate of the terminal configuration is improved.
207: the second network device enters an energy-saving mode of operation.
In the present application, the order of the steps is not limited. After receiving the request sent by the first network device, the second network device may directly enter the energy-saving operating mode when determining that the second network device may enter the energy-saving mode. That is, the second network device may not need to enter the energy-saving operation mode after receiving the third indication information. Alternatively, the second network device may send response information to the first network device after entering the energy saving operating mode, and receive third indication information from the first network device, and the like. In this case, the sequence of the steps may be: 201-202-207-203-204-205.
Further, 206 is not an essential step. In some application scenarios, the first network device may not need to send the third indication information to the second network device.
With continued reference to fig. 3, a schematic flow chart of still another conversion method from the dual-connection operation mode to the energy-saving operation mode provided by the embodiment of the present application is shown. It should be understood that fig. 3 shows steps or operations of the conversion method from the dual connection operation mode to the power saving operation mode, but the steps or operations are only examples, and other operations or variations of the respective operations in fig. 2 may be performed by the embodiment of the present application. As shown in fig. 3, the method for converting from the dual connection operation mode to the energy saving operation mode may include steps 301-307.
In step 301, the second network device determines whether a trigger condition for switching from the dual connectivity operating mode to the energy saving operating mode is satisfied.
In this embodiment, the trigger condition for switching from the dual connection operating mode to the energy saving operating mode may include one or more of the following:
the load capacity or the resource utilization rate of the first network equipment is lower than a first preset threshold value; the load capacity or the resource utilization rate of the second network equipment is lower than a second preset threshold value; the load capacity or the resource utilization rate of the first network equipment and the second network equipment 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 amount is lower than a fifth preset threshold value.
302, the second network device sends a working mode switching request for switching from the dual-connection working mode to the energy-saving working mode to the first network device when detecting that a trigger condition for switching from the dual-connection working mode to the energy-saving working mode is satisfied.
Here, the request for entering the energy saving operation mode may carry at least one of the following information: the second network equipment configures the information in the common channel in the energy-saving working mode; the second network equipment is used for configuring information of Radio Resource Management (RRM) measurement in an energy-saving working mode; the second network device is configured for channel state information, CSI, measurement in a power saving mode of operation.
303, the first network device sends a response message to the second network device to enter the energy saving mode of operation.
After receiving the request sent by the second network device, the first network device may determine whether to allow the second network device to enter the energy-saving operating mode according to the current state of the first network device. So that a response message accepting entry into the energy-saving operation mode or rejecting entry into the energy-saving operation mode can be sent to the first network device. The response information may take the form of a 1-bit value.
And 304, the first network equipment sends first indication information for indicating to enter the energy-saving working mode to a terminal connected with the second network equipment.
After determining that the second network device is allowed to enter the energy-saving operating mode, the first network device may send first indication information to a terminal connected to the second network device. The specific content of the first indication information may refer to the content of the first indication information shown in 204, which is not described herein again.
305, the terminal sends second indication information to the first network device.
306: and the first network equipment sends the third indication information to the second network equipment.
307: the second network enters an energy-saving mode of operation.
The specific implementation of 305-307 and the content included in each indication information can refer to the specific description of 205-207 shown in fig. 2, and will not be described herein again.
As can be seen from fig. 3, unlike the embodiment shown in fig. 2, the embodiment shown in fig. 3 is that the second network device determines whether a trigger condition for the transition from the dual connection mode to the power saving mode is satisfied. Therefore, the first network equipment and the second network equipment can simultaneously monitor the power consumption of the double-connection system, the monitoring effect is improved, and the reduction of the power consumption of the double-connection system is facilitated.
With continued reference to fig. 4, a schematic flow chart of a method for converting from the power saving operation mode to the dual connection operation mode according to an embodiment of the present application is shown. As shown in fig. 4, the method for converting from the energy saving operation mode to the dual connection operation mode may include steps 401 and 407.
401. The first network device determines whether a trigger condition for a transition from the energy-saving operating mode to the dual-connectivity operating mode is satisfied.
In this embodiment, the trigger condition for switching from the energy-saving operating mode to the dual-connection operating mode may include one or more of the following:
the load capacity or the resource utilization rate of the first network equipment 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 equipment; the energy consumption of the first network is larger than a preset threshold value, and the sum of the energy consumption of the first network equipment and the energy consumption of the second network equipment is smaller than the energy consumption of the first network under the double-connection working mode.
Specifically, when the load of the first network device is higher than a first preset threshold, it indicates that the data transmission amount of the terminal exceeds the load of the first network device, and the data transmission with the terminal cannot be assumed only through the first network device. At this point, the second network device may be triggered to enter the dual-connectivity mode of operation.
The resources in the above resource utilization may include, but are not limited to, frequency domain resource utilization, time domain resource utilization, and the like, as examples. The specific included resources may refer to the description of the resources in 201, and are not described herein again. When the resource utilization rate of the first network device is higher than the preset threshold value, it indicates that the data transmission amount of the terminal exceeds the load amount of the first network device, and the data transmission with the terminal cannot be undertaken only through the first network device. At this point, the second network device may be triggered to enter the dual-connectivity mode of operation.
In a specific application scenario, the current maximum data transmission rate of the first network device and the terminal is 100 Mbit/s. And the data transmission rate requested by the terminal is 200 Mbit/s. Although the load amount of the first network device is not higher than the preset threshold value at this time, the maximum data transmission rate of the first network device is smaller than the data transmission rate requested by the terminal. At this point, the second network device may be triggered to enter the dual-connectivity mode of operation.
The first network device may estimate the energy consumption of the network device according to the load amount of the network device. When the first network device estimates that the power consumption of the first network device is larger than the preset threshold value and the second network device enters the dual-connection mode, the first network device transfers part of the load to the second network device, and at this time, the total power consumption of the first network device and the second network device is smaller 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.
402. When detecting that a trigger condition for converting the energy-saving working mode into the double-connection working mode is met, the first network equipment sends a working mode conversion request for converting the energy-saving working mode into the double-connection working mode to the second network equipment.
In this embodiment, the first network device may send a request to enter the dual-connection operating mode to the first network device when detecting that at least one trigger condition shown in 401 is satisfied.
In one possible implementation, the first network device may send bitstream data to the second network device directly instructing the second network device to enter the dual-connection operating mode.
In a possible implementation manner, the first network device may send the request to the second network device in a bitmap (bitmap) manner, and simultaneously, a bit is used to inquire whether the second network device can enter the dual connectivity mode.
In a possible implementation manner, when the first network device sends the request for entering the dual connectivity mode to the second network device, the configuration parameter that needs to be returned by the second network device may also be included. When the second network device enters the dual connectivity operating mode, various parameters need to be reconfigured so that the terminal can access the second network device quickly.
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: the second network equipment configures the information in the common channel under the double-connection working mode; the second network equipment is in the configuration information of the physical random access channel PRACH under the double-connection working mode; the second network equipment configures the information in the common channel under the double-connection working mode; the second network device is configured for RRM measurement of radio resource management in the dual connectivity mode of operation. Here, the configuration parameters may be requested in a bitmap manner, wherein one bit may represent one configuration parameter being queried.
It should be noted here that the first network device may not ask the second network device for configuration parameters in the dual connectivity operating mode in the request sent to the second network device by the first network device.
403, the second network device sends a response message to the first network device to enter the dual connectivity mode of operation.
In this embodiment, the second network device may send, based on the current state, a response message accepting to enter the dual-connection operating mode or rejecting to enter the dual-connection operating mode to the first network device. The response information may take the form of a 1-bit value. Specifically, when the bit value is "1", it may indicate that the entry into the operating mode is accepted; when the bit value is "0", it may indicate that entry into the dual connection operation mode is denied.
In some possible implementations, when the second network device rejects entering the dual-connection operating mode, the cause value of the rejection may also be indicated using a bitstream.
When the second network device is accepting to enter the dual connectivity mode of operation, the response information of the second network device may include at least one of: the second network equipment is in the configuration information of the physical random access channel PRACH under the double-connection working mode; the second network equipment configures the information in the common channel under the double-connection working mode; and the second network equipment is used for configuring the configuration information of the RRM measurement in the wireless work mode.
And 404, the first network device sends first indication information for indicating to enter the energy-saving working mode to a terminal connected with the second network device.
When the second network device is in the energy-saving operating mode, part of or all of the carriers in the second network device operate in a deactivated state. When the second network device is switched from the energy-saving operating mode to the dual-connection operating mode, the carriers of the second network device need to be activated, so that each carrier operates in an activated state.
The first network device may record a terminal ID connected to the second network device. Thus, which terminals are converted from the power saving operation mode to the dual connection operation mode can be notified by the terminal ID.
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 active state, and the carrier index is used to indicate which carriers in the SCG enter the active state. Wherein, both the SCG index and the carrier index can be set in a bitmap manner.
Optionally, the first network device may learn, from response information received from the second network device, whether configuration information for RRM measurement and a common channel cycle of the second network device are changed when the energy-saving operating mode is switched to the dual-connection operating mode. When the first network device determines that the configuration information and the common channel period for RRM measurement are changed, the first indication information further needs to include the configuration information and the common channel period for RRM measurement of the second network device.
And 405, the terminal sends second indication information to the first network equipment.
In this embodiment, the second indication information is used to indicate that the terminal configuration is completed.
The specific implementation of this step can refer to the description of 205 shown in fig. 2, and is not described herein again.
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 the DIC signaling, it is equivalent to instruct the terminal to enter the dual connectivity operating mode. At this time, the terminal does not need to transmit the second indication information to the second network device.
406: the terminal sends a random access request to the second network device.
In this embodiment, after the terminal receives the first indication information from the first network device, each parameter may be configured based on the first indication information. Therefore, after the terminal completes the configuration of each parameter, the terminal can send a random access request to the second network device.
407: and the second network equipment determines that the terminal is successfully accessed randomly and enters a double-connection working mode.
In this embodiment, after the second network device determines that the terminal random access is successful, it may be determined that the dual connectivity operating mode is entered. At this time, data transmission with the terminal is possible.
It should be understood that fig. 4 shows steps or operations of the conversion method from the energy saving operation mode to the dual connection operation mode, but the steps or operations are only examples, and other operations or variations of the operations in fig. 4 may be performed by the embodiments of the present application. Moreover, the various steps in FIG. 4 may be performed in a different order presented in FIG. 4, and it is possible that not all of the operations in FIG. 4 may be performed. For example, after receiving the first indication information sent by the first network device, the terminal may directly send the random access request to the second network device without sending the second indication information to the first network device. At this time, 405 is not a step that has to be performed.
As can be seen from the embodiments shown in fig. 2 to fig. 4, in the process of the second network device converting from the energy-saving operation mode to the dual-connection operation mode or from the dual-connection operation mode to the energy-saving operation mode, each time the second network device performs the operation conversion, the second network device needs to exchange configuration information such as common information and RRM measurement with the first network device and the terminal.
Please continue to refer to fig. 5, which shows a schematic flowchart of a method for pre-configuring parameters of an energy saving operation mode according to an embodiment of the present application. The second network device may pre-configure the parameters of the energy saving mode of operation before entering the energy saving mode of operation for the first time. Therefore, the subsequent second network device does not need to exchange configuration information such as RRM measurement to the first network device each time in performing the mode switching engineering, so that the signaling overhead can be further reduced. The method for pre-configuring the parameters of the energy-saving operation mode is described in detail with reference to fig. 5.
501. The second network device sends the configuration information in the energy-saving operation mode to the first network device.
In this embodiment, the configuration information of the second network device in the energy saving operation mode may include one or more sets of configuration parameters. Each set of configuration parameters includes a configuration identifier, which may also be referred to as a configuration index, corresponding to the set of configuration parameters. Each set of configuration parameters further includes at least one of: common channel configuration information, configuration information for radio resource management, RRM, measurements and configuration information for channel state information, CSI, measurements.
Specifically, when the configuration information includes a plurality of sets of configuration parameters, each set of configuration parameters is different. That is, the common channel configuration information of the configuration identifier 1, the configuration information of the RRM measurement, and the configuration information of the CSI measurement are different from the common channel configuration information of the configuration identifier 2, the configuration information of the RRM measurement, and the configuration information of the CSI measurement. Generally, the longer the configuration parameters, such as RRM measurement period, common channel transmission period, etc., are configured, the greater the energy saving gain. Therefore, when the second network enters the energy-saving working mode, one group of configuration parameters with the longest adoption period can be selected from the plurality of groups of configuration parameters.
In some scenarios, the terminal cannot keep synchronization with the second network device due to the RRM measurement period and the too long common channel transmission period, or the terminal cannot measure the second network device for a certain time. At this time, the terminal will typically trigger a request to delete the second network device. After receiving the request, the second network device may reselect a set of configuration parameters and send the selected configuration parameters to the first network device, so that the first network device may send the new configuration parameters to the terminal.
In order to facilitate the subsequent terminal to keep performing RRM measurement and synchronization signal detection on the second network device when the second network device enters the energy saving mode, when performing the energy saving operation mode pre-configuration, the second network device needs to send each set of configuration parameters to the first network device.
502, the first network device sends the configuration information of the second network device in the energy-saving working mode to the terminal.
After receiving the configuration information in the energy-saving operating mode sent by the second network device, the first network device may send the configuration information to the terminal, so that the terminal performs configuration for different configuration parameters when the second network device enters the energy-saving operating mode.
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; alternatively, the first network device may send the pre-configuration information through DCI signaling.
Optionally, before or after this step, the first network device may also send response information to the second network device. Thus, the second network device may determine whether the first network device receives a configuration of the second network device in the energy-saving mode of operation. Meanwhile, in the response information sent by the first network device to the second network device, 1 bit may be used to indicate whether to accept the configuration request of the second network device, and when the configuration request of the second network device is indicated to be rejected, a plurality of bits may also be used to indicate a reason value for rejection.
Optionally, after receiving the configuration information of the second network device in the energy-saving operating mode sent by the first network, the terminal may perform configuration based on the configuration information. After the configuration is completed, indication information of the completion of the configuration may be sent to the first network device. As an example, when the first network device sends the first indication information to the terminal through RRC signaling, the terminal may send information indicating that the configuration is completed to the first network device through RRC signaling. When the first network device sends the first indication information to the terminal through the MAC CE signaling, the terminal may send information indicating that the configuration is completed to the first network device through the MAC CE signaling. When the first network device sends the first indication information to the terminal through DCI signaling, the terminal may not need to send the indication information that the configuration is completed to the first network device.
Based on the pre-configuration of the second network device information in the energy saving operation mode as shown in fig. 5, a method for converting from the dual connectivity operation mode to the energy saving operation mode will be further described with reference to fig. 2.
Here, after the energy saving operation mode is preconfigured, the conversion procedure from the dual connection operation mode to the energy saving operation mode is the same as the interaction procedure between the devices shown in fig. 2. In contrast, the content such as request information, response information, and indication information transmitted by each device is different.
In 202 shown in fig. 2, when the first network device sends a request for entering the energy saving operating mode to the second network device, except for requesting the second network device to enter the energy saving operating mode, the first network device may carry a configuration identifier for inquiring configuration parameters used by the second network device in the energy saving operating mode. That is, since the configuration parameters have been configured for the common channel configuration information, the configuration information of RRM measurement, the configuration information of CSI measurement, and the like before, the first network device may not need to query the common channel configuration information, the configuration information of RRM measurement, the configuration information of CSI measurement, and the like, thereby reducing signaling overhead.
In 203 shown in fig. 2, the response message sent by the second network device to the first network device includes, in addition to the indication whether the energy-saving operating mode can be entered, a configuration identifier of the configuration parameters used when entering the energy-saving operating mode. Specifically, the second network device may indicate the configuration identifier of the adopted configuration parameter in a bitmap manner. Assuming that the second network device is preconfigured with 5 sets of configuration parameters, a 5-bit bitmap indication may be adopted, where a first bit is used to indicate configuration identifier 1, a second bit is used to indicate configuration identifier 2, a third bit is used to indicate configuration identifier 3, a fourth bit is used to indicate configuration identifier 4, and a fifth bit is used to indicate configuration identifier 5. In each bit, "0" represents that the configuration parameter corresponding to the configuration identifier is not adopted, and "1" represents that the configuration parameter corresponding to the configuration identifier is adopted. When the second network device adopts the configuration parameter corresponding to the configuration identifier 2, it may set the bitmap to "01000", thereby indicating that the configuration identifier 2 is adopted for the configuration parameter.
In 204 shown in fig. 2, the first indication information, which is sent by the first network device to the terminal and used for indicating to enter the energy saving operating mode, includes, in addition to one or more of status information used for indicating a cell in a cell set SCG of the second network device in the energy saving operating mode and status information used for indicating a carrier of the second network device in the energy saving operating mode, a configuration identifier corresponding to a configuration parameter used when the second network device is indicated to enter the energy saving operating mode.
Based on the pre-configuration of the second network device information in the energy saving operation mode as shown in fig. 5, further referring to fig. 3, another conversion method for converting from the dual connectivity operation mode to the energy saving operation mode is further described.
Here, after the energy saving operation mode is preconfigured, the conversion procedure from the dual connection operation mode to the energy saving operation mode is the same as the interaction procedure between the devices shown in fig. 3. In contrast, the content such as request information, response information, and indication information transmitted by each device is different.
In 302 shown in fig. 3, when the second network device sends a request for entering the energy saving operating mode to the first network device, the second network device may also carry a configuration identifier of a configuration parameter used by the second network device in the energy saving operating mode, in addition to the request for entering the energy saving operating mode.
In 304 shown in fig. 3, in the first indication information sent by the first network device to the terminal, the first indication information is used to indicate to enter the energy saving operating mode, and the first indication information includes, in addition to one or more of status information used to indicate cells in the cell set SCG of the second network device in the energy saving operating mode and status information used to indicate carriers of the second network device in the energy saving operating mode, a configuration identifier corresponding to a configuration parameter used when the second network device is indicated to enter the energy saving operating mode.
Based on the pre-configuration of the second network device information in the energy saving operation mode as shown in fig. 5, a method for converting from the energy saving operation mode to the dual connectivity operation mode will be further described with reference to fig. 4.
Here, after the energy saving operation mode is preconfigured, the conversion step of converting the energy saving operation mode into the dual connection operation mode is the same as the interaction step between the devices shown in fig. 4. In contrast, the content such as request information, response information, and indication information transmitted by each device is different.
In 402 shown in fig. 4, when the first network device sends a request for entering the dual connectivity operating mode to the second network device, except for requesting the second network device to enter the dual connectivity operating mode, the first network device may carry a configuration identifier corresponding to a configuration parameter for inquiring that the second network device needs to cancel when entering the dual connectivity operating mode. Here, the first network device, the second network device, and the terminal may agree on configuration parameters in the dual connectivity operating mode, and by canceling the configuration identifier corresponding to the configuration parameters used by the second network device in the energy saving operating mode, parameters such as common channel configuration information, RRM measurement configuration information, CSI measurement configuration information, and the like may be reset, that is, it is considered that the configuration parameters in the dual connectivity operating mode are used, so that the first network device may not inquire the configuration parameters in the dual connectivity operating mode any more, and signaling overhead is reduced.
In 403 shown in fig. 4, the response message sent by the second network device to the first network device includes a configuration identifier to be cancelled, in addition to an indication of whether the dual connectivity operating mode can be entered. Specifically, the second network device may indicate the configuration identifier corresponding to the cancelled configuration parameter in a bitmap manner. Assuming that the second network device is preconfigured with 5 sets of configuration parameters, when the second network device adopts the configuration parameters corresponding to the configuration identifier 2 in the energy-saving operating state, the bitmap may be set to "00000", so as to indicate to cancel the configuration parameters corresponding to the configuration identifier 2.
In 404 shown in fig. 4, the first indication information, which is sent by the first network device to the terminal and used for indicating to enter the energy-saving operating mode, includes, in addition to one or more of status information used for indicating a cell in the cell set SCG of the second network device in the energy-saving operating mode and status information used for indicating a carrier of the second network device in the energy-saving operating mode, a configuration identifier corresponding to a configuration parameter to be cancelled when the second network device enters the dual-connection operating mode.
