The power consumption of the ue has been an important issue concerned by mobile communication, and various schemes for improving the power consumption of the ue, such as Connected Discontinuous Reception (CDRX), Bandwidth Part (BWP), uplink intelligent pre-scheduling, and uplink waveform dynamic adaptation, are as follows:
connected Discontinuous Reception (CDRX): the specific scheme is that after user equipment enters a Radio Resource CONTROL (RRC) connection state, a 4G base station eNB and a 5G base station gNB respectively configure CDRX parameters, and the user equipment periodically wakes up to receive downlink data, so that the power consumption of the user equipment is saved.
Bwp (bandwidth part): the working principle is as shown in fig. 4, the larger the working bandwidth of the user equipment UE is, the higher the power consumption is. Compared with 4G and 5G, the bandwidth is increased from 20MHz to 100MHz, the sampling rate of the front-end analog signal is increased, and the signal processing complexity of the algorithm module is increased. BWP allows the UE to operate on a fraction of the total bandwidth. When the UE transmits low-rate service, the UE works in narrow bandwidth; when the UE transmits high-rate service, the UE works in large bandwidth.
Uplink intelligent pre-scheduling: as shown in fig. 5, compared with the conventional uplink pre-Scheduling that the periodic pre-Scheduling is triggered after the UE sends a Scheduling Request (SR), the intelligent pre-Scheduling is based on the fact that the pre-Scheduling is triggered when a downlink data packet arrives, which can effectively solve the problem that the UE cannot enter a CDRX dormant period after the conventional uplink pre-Scheduling is started, and ensure that the data upload delay is short and the power consumption is moderate.
Dynamic self-adaptation of uplink waveforms: the PAPR of the LTE uplink and the new air interface NR physical layer uplink DFT-S-OFDM is smaller than that of the NR physical layer uplink and downlink CP-OFDM, so the DFT-S-OFDM is adopted, the linearity reserved space of a PA (radio frequency power amplifier) of the user equipment is larger, the working efficiency of the PA is higher, and the lower power consumption can be used for achieving the same transmitting power as the CP-OFDM; on the contrary, under the same power consumption, the power transmitted by DFT-S-OFDM is higher (the transmission power of PA is higher by 1dB), and the uplink coverage area can be effectively increased. The current base station mainly adopts CP-OFDM, compared with DFT-S-OFMD, CP-OFDM can adjust uplink 2 flow, supports discontinuous scheduling, and has higher frequency spectrum utilization rate. But it is suggested that at the cell edge, the base station can support the dynamic adjustment of the uplink waveform to DFT-S-OFDM by Radio Resource CONTROL (RRC) signaling reconfiguration.
The above existing power consumption improvement schemes are more oriented to power consumption optimization performed when the user equipment is already in LTE (LONG TERM EVOLUTION) -NR dual connectivity. No matter C-DRX, BWP, uplink intelligent language scheduling and uplink waveform self-adaption, the power consumption of the NR auxiliary carrier side is optimized by considering that the user equipment is in a double-connection state. In addition, in the use of actual user equipment, a plurality of scenes exist, and the speed of the 4G network can meet the use requirements of users, such as WeChat, web browsing, mobile payment, dripping and dropping car and the like.
Under a NON-independent networking mode (NSA), the user equipment is required to maintain double connection of LONG TERM EVOLUTION (LTE) -NR, a chip Transceiver and a radio frequency PA of the user equipment always have two channels in a working state, particularly, the NR frequency band of the other channel is 100MHz bandwidth, and compared with 4G 20MHz, the power consumption of the user equipment is improved by about 5 times. Meanwhile, in the existing applications, the speed of many services (such as WeChat chat, web browsing, and news reading) is not always required to be high.
Fig. 6 shows a schematic diagram of an overall architecture of a non-independent network in a fifth generation mobile communication system, as shown in fig. 6, a core network of the non-independent network architecture is still epc (evolved Packet core), a user equipment is anchored in a 4G frequency band, and can access the core network through LONG TERM EVOLUTION over 4G wireless air interface (LTE), and for data bearer, dual connectivity of LONG TERM EVOLUTION (LONG TERM EVOLUTION, NR-LTE) with NR SECONDARY CELL GROUP (SCG) can be used for service plane data transmission.
The 4G wireless air interface single carrier is 20MHz, the 5G wireless air interface auxiliary carrier is 100MHz, and the rate of the user equipment after adding the new air interface NR auxiliary carrier is greatly increased (4G network downlink theoretical rate 100Mbps, 5G network downlink theoretical rate 1.7Gbps, but when the rate is increased, the power consumption of the user equipment is also significantly increased.
In order to solve the problem of the prior art, embodiments of the present application provide a method, an apparatus, a device, and a storage medium for reducing power consumption of a user equipment. The method and the device can intelligently judge whether the SCG of the auxiliary cell group needs to be added or removed based on the condition that the auxiliary cell group is added to the user equipment cell and the transmission rate of the current transmission service of the user equipment, and do not add or remove the SCG during the low-rate service transmission of the user equipment, thereby reducing the current power consumption of the 5G user equipment. First, a method for reducing power consumption of a user equipment provided in an embodiment of the present application is described below.
Fig. 7 is a flowchart illustrating a method for reducing power consumption of a user equipment according to an embodiment of the present application. As shown in fig. 7, the method may include the steps of:
s70, when entering LTE connection state from LTE idle state, determining whether the cell to which the user equipment belongs is added with an auxiliary cell group SCG, and determining the transmission rate of the current transmission service of the user equipment.
When entering the LTE connected state from the long term evolution LTE idle state, the 5G user equipment may be in one of two states: dual connectivity with the addition of SCG state, i.e. in LONG TERM EVOLUTION (LTE) -NR; and, no SCG state is added, i.e. not in dual connectivity for LONG TERM EVOLUTION (LTE) -NR.
And S72, when the SCG is not added to the cell to which the UE belongs and the transmission rate is lower than the preset rate, not reporting a first measurement report to the network equipment to which the UE belongs, wherein the first measurement report indicates that the service quality of the SCG is greater than the preset threshold.
In the prior art, when the service quality of the SCG is greater than a preset threshold (generally, it may be set to-115 dBm), the user equipment may report a first measurement report, and the 4G anchor CELL equipment may perform an add NR CELL SCG (secondary CELL group) operation. Fig. 8 shows a schematic diagram of signaling interaction between a ue and a network device to which the ue belongs in an embodiment of the present application, as shown in fig. 8, in the embodiment of the present application, when a transmission rate is lower than a preset rate, a first measurement report is not reported to the network device to which the ue belongs, and the network device cannot add NR SCG to the ue, so as to achieve a target of reducing power consumption of the ue.
And S74, when the user equipment is added with the SCG and the transmission rate is lower than the preset rate, sending the information of removing the SCG to the network equipment.
As shown in fig. 8, when the SCG is added to the ue and the transmission rate is lower than the preset rate, it indicates that the ue does not need to use dual connectivity, and sends the information of tearing down the SCG to the network device.
In one embodiment, tearing down SCG information may include at least one of:
t310 timer timeout information, SCG synchronization failure information, Secondary Cell Group Media Access Control (SCG MAC) random Access problem information, Secondary Cell Group Radio Link Control (SCG RLC) maximum retransmission number information, Signaling Radio Bearer (SRB) 3 integrity check failure information, and neighboring Cell Radio Resource Control (RRC) reconfiguration failure message.
In the prior art, after receiving the SCG Failure information, the network device may perform an SCG teardown operation. The 3GPP specifies SCG Failure mainly for several reasons:
when the T310 timer is overtime, the UE reports SCG Failure Information NR, and the reason is defined as T310-overtime;
the SCG synchronization fails, the user equipment requests for reconfiguration, and the UE reports SCG Failure Information NR, wherein the reason is defined as syncReconfiguration Failure-SCG;
the SCG MAC random access has problems, UE reports SCG FailureInformationNR, and the reason is defined as randomaccessfbleitem;
the SCG RLC reaches the maximum retransmission times, and the UE reports SCG FailureInformationNR, wherein the reason is defined as RLC-MaxNumRetx;
if the SRB3 fails in integrity check, the UE reports SCG FailureInformationNR, and the reason is defined as SRB 3-IntegrtyFailure;
the reconfiguration failure of the NR Radio Resource CONTROL (RRC) reconfiguration message may report SCG failure information NR for the reason defined as SCG-reconfigurgfailure.
Therefore, in the embodiment of the present application, the removal SCG information is set as SCG Failure information. After receiving the SCG Failure, the network can carry out the chain disconnection of the NR CELL SCG (SECONDARY CELL GROUP), thereby achieving the aim of reducing the power consumption of the user equipment.
In one embodiment, when the tearing down SCG information includes T310 timer timeout information, the tearing down SCG information further includes:
and a fault frequency measurement result list, wherein the content recorded in the preset position of the list is preset content.
Since most operators will use SCG Failure (cause value T310 time out) as an index for measuring the NR radio quality of the current network, frequent reporting of SCG Failure (T310 time out) by the ue will seriously affect the NR radio link index statistics of the current network due to the requirement of saving power consumption. In view of the drawbacks, in the embodiment of the present application, while the user equipment reports the removal SCG information (cause value T310 is overtime), a failure Frequency measurement result list is reported, and a Physical Cell Identifier (PCI) and an Absolute Radio Channel Number (Absolute Radio Frequency Channel Number-ARFCN) are reported at the same time. Different from normal reporting of the PCI and ARFCN of the current CELL, the user equipment actively releases the NR CELL scg (secondary CELL group) due to a low service rate, and the PCI and ARFCN of the user equipment are reported as 0. Referring to the 3GPP standard flow, ARFCN-ValueNR-r15 ═ 0 and pci-r15 ═ 0 are reported in MeasResultFreqListFailNR-r15, SEQUENCE ═ 1. The programming is as follows:
based on the fault frequency measurement result list, when the current network NR radio link index statistics fails, secondary association of cell information in the fault frequency measurement result list is carried out, and ARFCN-ValueNR-r15 in the fault frequency measurement result list is 0, and pci-r15 is 0, so that the statistics of the radio link failure is eliminated, and the truth and accuracy of the statistics are ensured.
In one embodiment, S74 may include:
an Application Platform (AP) layer of the ue triggers a base station Platform (base and Platform, BP) layer of the ue to send information for removing SCG.
In one embodiment, before detecting the transmission rate of the current transmission service of the user equipment, the method further includes:
detecting whether the time period of a window for detecting the transmission rate preset by an application platform AP layer of the user equipment is overtime or not; under the condition of not overtime, executing the detection of the transmission rate of the current transmission service of the user equipment; in case of a timeout, the time period of the window is reset, thereby ensuring the accuracy of the measured transmission rate.
The method for reducing the power consumption of the user equipment can intelligently judge whether the SCG of the auxiliary cell group needs to be added or removed or not based on the condition that the auxiliary cell group is added to the user equipment cell and the transmission rate of the current transmission service of the user equipment, and does not add or remove the SCG during the transmission of the low-rate service of the user equipment, so that the current power consumption of the 5G user equipment can be reduced.
Fig. 7-8 illustrate a method for reducing power consumption of a user equipment, and the following describes an apparatus provided by an embodiment of the present application with reference to fig. 9 and 10.
Fig. 9 is a schematic structural diagram illustrating an apparatus for reducing power consumption of a user equipment according to an embodiment of the present application, where each module in the apparatus shown in fig. 9 has a function of implementing each step in fig. 7, and can achieve the corresponding technical effect. As shown in fig. 9, the apparatus may include:
the determining module 90 is configured to determine whether the cell to which the ue belongs adds an auxiliary cell group SCG when entering an LTE connected state from an LTE idle state, and determine a transmission rate of a current service transmitted by the ue.
When entering the LTE connected state from the long term evolution LTE idle state, the 5G user equipment may be in one of two states: dual connectivity with SCG state added, i.e. in LONG TERM EVOLUTION (LTE) -NR; and, no SCG state is added, i.e. not in dual connectivity for LONG TERM EVOLUTION (LTE) -NR.
A sending module 92, configured to not report a first measurement report to a network device to which the ue belongs when the SCG is not added to the cell to which the ue belongs and the transmission rate is lower than the preset rate, where the first measurement report indicates that the service quality of the SCG is greater than a preset threshold.
In the prior art, when the service quality of the SCG is greater than a preset threshold (generally, it may be set to-115 dBm), the user equipment may report a first measurement report, and the 4G anchor CELL equipment may perform an add NR CELL SCG (secondary CELL group) operation. Fig. 8 is a schematic diagram illustrating signaling interaction between a ue and a network device to which the ue belongs in an embodiment of the present application, and as shown in fig. 8, in the embodiment of the present application, when a transmission rate is lower than a preset rate, a first measurement report is not reported to the network device to which the ue belongs, and the network device cannot add NR SCG to the ue, so as to achieve a goal of reducing power consumption of the ue.
A sending module 92, configured to send a teardown SCG message to the network device when the SCG is added to the user equipment and when the transmission rate is lower than the preset rate.
As shown in fig. 8, when the SCG is added to the ue and the transmission rate is lower than the preset rate, it indicates that the ue does not need to use dual connectivity, and sends the information of tearing down the SCG to the network device.
In one embodiment, tearing down SCG information may include at least one of:
t310 timer overtime information, SCG synchronization failure information, media access control layer SCG MAC random access problem information, SCG radio link layer control protocol RLC information of the maximum retransmission times, signaling radio bearer SRB integrity check failure information and adjacent cell radio resource control RRC reconfiguration failure information.
In the prior art, after receiving SCG Failure information, a network device may execute an SCG removal operation. The 3GPP specifies SCG Failure mainly for several reasons:
when the T310 timer is overtime, the UE reports SCG Failure Information NR, and the reason is defined as T310-overtime;
the SCG synchronization fails, the user equipment requests for reconfiguration, and the UE reports SCG Failure Information NR, wherein the reason is defined as syncReconfiguration Failure-SCG;
if the SCG MAC random access has a problem, the UE reports SCG FailureInformationNR, and the reason is defined as randomaccessprbleM;
the SCG RLC reaches the maximum retransmission times, and the UE reports SCG FailureInformationNR, wherein the reason is defined as RLC-MaxNumRetx;
if the SRB3 fails in integrity check, the UE reports SCG FailureInformationNR, and the reason is defined as SRB 3-IntegrtyFailure;
the reconfiguration failure of the NR Radio Resource CONTROL (RRC) reconfiguration message may report SCG failure information NR for the reason defined as SCG-reconfigurgfailure.
Therefore, in the embodiment of the present application, the removal SCG information is set as SCG Failure information. After receiving the SCG Failure, the network can carry out the chain disconnection of the NR CELL SCG (SECONDARY CELL GROUP), thereby achieving the aim of reducing the power consumption of the user equipment.
In one embodiment, when the tearing down SCG information includes T310 timer timeout information, the tearing down SCG information further includes:
and a fault frequency measurement result list, wherein the content recorded in the preset position of the list is preset content.
Since most operators will use SCG Failure (cause value T310 is overtime) as an index for measuring the NR radio quality of the existing network, frequent reporting of SCG Failure (T310 is overtime) by the user equipment will seriously affect the NR radio link index statistics of the existing network due to the requirement of saving power consumption. In view of the drawbacks, in the embodiment of the present application, while the user equipment reports the removal SCG information (cause value T310 is overtime), a failure Frequency measurement result list is reported, and a Physical Cell Identifier (PCI) and an Absolute Radio Frequency Channel Number (Absolute Radio Frequency Channel Number-ARFCN) are reported at the same time. Different from normal reporting of the PCI and ARFCN of the current CELL, the user equipment actively releases the NR CELL scg (secondary CELL group) due to a low service rate, and the PCI and ARFCN of the user equipment are reported as 0. Referring to the 3GPP standard flow, ARFCN-ValueNR-r15 ═ 0 and pci-r15 ═ 0 are reported in MeasResultFreqListFailNR-r15, SEQUENCE ═ 1. The programming is as follows:
based on the fault frequency measurement result list, when the current network NR radio link index statistics fails, secondary association of cell information in the fault frequency measurement result list is carried out, and ARFCN-ValueNR-r15 in the fault frequency measurement result list is 0, and pci-r15 is 0, so that the statistics of the radio link failure is eliminated, and the truth and accuracy of the statistics are ensured.
In one embodiment, the sending module 92 may be specifically configured to:
an Application Platform (AP) layer of the ue triggers a base station Platform (base and Platform, BP) layer of the ue to send information for removing SCG.
In an embodiment, the apparatus further includes a detecting module 94, configured to detect whether a time period of a window for detecting a transmission rate preset by an AP layer of an application platform of the ue is overtime before detecting a transmission rate of a current service transmitted by the ue; under the condition of not overtime, executing the detection of the transmission rate of the current transmission service of the user equipment; in case of a timeout, the time period of the window is reset, thereby ensuring the accuracy of the measured transmission rate.
The device for reducing the power consumption of the user equipment can intelligently judge whether the SCG of the auxiliary cell group needs to be added or removed or not based on the condition that the auxiliary cell group is added to the user equipment cell and the transmission rate of the current transmission service of the user equipment, and does not add or remove the SCG during the transmission of the low-rate service of the user equipment, so that the current power consumption of the 5G user equipment can be reduced.
