Description

[0001] The present application claims priority on the basis of Chinese Patent Application No. 201910951471.3, filed with the National Intellectual Property Office of China on October 8, 2019 and entitled "METHOD AND APPARATUS FOR REDUCING UE POWER CONSUMPTION", which is hereby incorporated herein in its entirety. completeness.

FIELD OF TECHNOLOGY

[0002] The present invention relates to the field of wireless communication technologies and, in particular, to a method and hardware system for reducing the power consumption of a UE (User Equipment, user equipment).

BACKGROUND OF THE INVENTION

[0003] At present, network modes in 5G technology (5th generation mobile networks or 5th generation wireless systems, 5th generation mobile communication technology) of terminal devices can be roughly divided into two types: NSA (Non-Standalone, Non-Autonomous ) and SA (Standalone, autonomous). NSA technology means that both LTE (Long Term Evolution) and NR (New Radio) are online. In this case, the UE needs to support two online modes at the same time, and it is necessary to support two RF channel sets, and hence the power consumption is relatively high. In SA technology, the supported specifications are higher than those of 4G (the fourth generation of mobile phone mobile communication technology standards), i.e. higher speed, higher bandwidth and more RF antennas are supported. . Therefore, the power consumption is also higher than that of 4G.

[0004] When the 5G era comes, the operator provides high traffic packages, but usually does not provide unlimited high-speed data packages. The common practice is as follows: When the traffic in the user's packet is less than x GB, the use of 5G is not limited, and the speed is not limited; and when the traffic used by the user exceeds x GB, the user's Internet speed is limited and the user cannot enjoy the high-speed capabilities of 5G. In the prior art, after the network packet of the UE is used up, the operator limits the Internet speed of the UE, but does not solve the problem of the subsequent scenario after the limitation of the Internet speed: the UE is still bound to a high power consumption network standard, but has a relatively low Internet speed . In addition, in the prior art, there is a criterion for transitioning back from 4G to 3G (3 ^rd -Generation of Wireless Mobile Telecommunications Technology, 3rd generation of wireless mobile telecommunications technology) (or to another network standard such as 2G (Second Generation of Wireless Mobile Telecommunications Technology, based on the remaining traffic, power and other operating state of the UE. However, in the prior art, the specificity of 5G technology is not allowed; in particular, there is no measure to reduce power consumption in NSA and SA network modes. In addition, the prior art fails to consider that during the downgrading process from 4G to 3G, the corresponding icons change and the UE network standard icon changes from 4G to 3G, thereby degrading the user's sensory experience.

[0005] Based on this prior art, the present invention provides a method and a hardware system (apparatus) for reducing the power consumption of a UE in order to solve the problem that after limiting the Internet speed of a UE that supports 5G, the UE cannot use 5G high-speed access to the Internet, but must endure high power consumption.

SUMMARY OF THE INVENTION

[0006] The present invention provides a method and a hardware system for reducing the power consumption of a UE to effectively reduce the power consumption of the UE and extend the waiting time of the UE when determining whether the UE's Internet speed is limited in 5G mode, thereby improving the user experience. The specific content of the present invention is as follows:

[0007] According to a first aspect, the present invention provides a method for reducing the power consumption of a user equipment (UE), wherein the specific content of the method includes: the UE obtains a network configuration parameter of the UE, wherein, to distinguish from the existing technical solution, the UE is an electronic device, which supports the non-standalone network mode of the 5th generation mobile communication technology (5G NSA) and/or the standalone network mode of the 5th generation mobile communication technology (5G SA); after the UE receives the network configuration parameter of the UE, the UE determines the value of the network configuration parameter of the UE and the set threshold value, and the UE determines whether the network configuration parameter of the UE is less than the set threshold value; and if the network configuration parameter of the UE is smaller than the set threshold, it indicates that the UE's Internet speed is limited, and the UE starts a power reduction procedure. Thus, unnecessary power consumption of the UE can be effectively reduced, thereby prolonging the UE's latency and improving the user experience.

[0008] In an exemplary implementation of the first aspect of the present invention, when the UE is in 5G NSA network mode, the network configuration parameter of the UE includes an Access Point Identifier - Aggregated Maximum Transfer Rate (APN-AMBR) parameter, where APN-AMBR is an upper bound the sum of the rates of all non-guaranteed rate (non-GBR) bearers for an access point identifier (APN), with the APN-specific APN-AMBR being used as the subscription parameter of each APN to limit the aggregate rate of all network connections public data transfer (PDN) in the same APN, and the value of the APN-AMBR parameter may indicate the Internet speed allocated by the network operator to the UE; or when the UE is in 5G SA network mode, the network configuration parameter of the UE includes a per-session aggregated maximum transmission rate (Session-AMBR) parameter, wherein the Session-AMBR is an upper bound on the sum of the transmission rates of all Quality of Service (QoS) flows with non-GBR for a protocol data unit (PDU) session, and the value of the Session-AMBR parameter may represent the Internet speed allocated by the network operator to the UE. Thus, the network configuration parameter of the UE can be used to determine whether the UE's Internet speed is limited, so that the UE determines whether to perform the power reduction procedure.

[0009] In an exemplary implementation of the first aspect of the present invention, a method for determining by the UE whether the network configuration parameter of the UE is less than the set threshold includes the following: when the UE is in the 5G NSA network mode, the UE determines whether the uplink rate is less communication in the APN-AMBR parameter than the set first threshold value, and/or the UE determines whether the downlink rate in the APN-AMBR parameter is less than the set second threshold value; or when the UE is in the 5G SA network mode, the UE determines whether the uplink rate in the Session-AMBR is less than the set third threshold, and/or the UE determines whether the downlink rate in the Session-AMBR is less than set fourth threshold value. Thus, the UE can determine whether the UE's Internet speed is limited, so that the UE determines whether to perform the power reduction procedure.

[0010] In an exemplary implementation of the first aspect of the present invention, before the UE determines whether the network configuration parameter of the UE is less than the set threshold, setting by the UE of the set threshold is further included, and a method for setting the set by the threshold by the UE includes: itself as follows: the UE uses the first value input by the user as the set threshold value; or the UE sets the UE network configuration parameter value, which is obtained when the UE's Internet speed is not limited, as the set threshold value. Thus, the UE can determine based on the set threshold whether the Internet speed of the UE is limited, so that the UE determines whether to perform the power reduction procedure. Thus, the set threshold can be used as a metric for determining whether the UE's Internet speed is limited, so that the UE determines whether to perform a power reduction procedure.

[0011] In an exemplary implementation of the first aspect of the present invention, after the UE starts the power down procedure, the method further includes: the UE determines whether the UE has performed the power down procedure; the UE determines whether the network configuration parameter of the UE is less than the set threshold value; and if the UE has performed the power down procedure and the network configuration parameter of the UE is not less than the set threshold, the UE starts the recovery procedure, the UE's operating state before the UE starts the power reduction procedure is the first operating state, the UE's operating state after the UE starts the power reduction procedure is the second operating state, and that the UE starts the recovery procedure indicates a process in which the UE's operating state is changed from the second operating state to the first operating state. Thus, the UE can start the recovery procedure based on the actual situation to reach the optimal operating state.

[0012] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G NSA network mode, a method for triggering a power reduction procedure by that UE includes: disabling the NR and LTE dual EN-DC connectivity of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0013] In an exemplary implementation of the first aspect of the present invention, when the UE is in the 5G NSA network mode, a method for starting a power reduction procedure by that UE includes: turning off the millimeter wave function of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0014] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G NSA network mode, a method for triggering a power reduction procedure by that UE includes: without disabling the EN-DC capability of 5G New Radio (NR) dual connection and long-term evolution (LTE) of the said UE, skipping a new radio (NR) neighbor cell measurement, and skipping a response to a secondary cell group (SCG) addition action on the network side. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0015] In an exemplary implementation of the first aspect of the present invention, when the UE is in the 5G NSA network mode, a method for triggering a power reduction procedure by that UE includes the following: the UE retains the EN-DC capability of NR and LTE dual connectivity, and downgrades the antenna configuration resources of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0016] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G NSA network mode, a method for triggering a power reduction procedure by that UE includes: turning off the new radio carrier aggregation (NR-CA) function of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0017] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G NSA network mode, a method for triggering a power reduction procedure by that UE includes: truncating the carrier component (CC) capability of said UE in LTE and NR. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0018] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G NSA network mode, a method for triggering a power reduction procedure by that UE includes the following: the UE disables the EN-DC capability of NR and LTE dual connectivity and adjusts the CAT capability category LTE access of said UE based on the Internet speed limit of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0019] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G SA network mode, a method for starting a power reduction procedure by that UE includes: turning off the millimeter wave function of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0020] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G SA network mode, a method for triggering a power reduction procedure by that UE includes the following: the UE continues camping in NR and down-configures the antenna resources of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0021] In an exemplary implementation of the first aspect of the present invention, when the UE is in a 5G SA network mode, a method for starting a power reduction procedure by that UE includes the following: the UE continues camping in NR; and turning off the new radio carrier aggregation (NR-CA) function of said UE. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0022] In an exemplary implementation of the first aspect of the present invention, when a UE is in a 5G SA network mode, a method for triggering a power reduction procedure by that UE includes the following: the UE uses fewer Carrier Components (CCs); or the UE is using a lower aggregated bandwidth. Thus, the UE can effectively reduce the power consumption and extend the latency, thereby improving the user experience.

[0023] According to a second aspect, the present invention provides a hardware system for reducing power consumption of a user equipment (UE), the hardware system including an acquisition module 300, a determination module 400, a power reduction procedure execution module 500, and a recovery procedure execution module 600. The acquisition unit 300 is configured to obtain the network configuration parameter of the UE and record the power reduction procedure of the UE, wherein the UE is an electronic device that supports 5G NSA network mode and/or 5G SA network mode. The determining unit 400 is configured to determine whether the network configuration parameter of the UE is less than the set threshold value and determine whether the UE has performed a power reduction procedure, wherein the fact that the parameter is less than the set threshold value is used to indicate that the Internet speed UE is limited. The power reduction procedure execution unit 500 is configured: when the determining unit 400 determines that the network configuration parameter of the UE is less than the set threshold value, performing the UE's power reduction procedure. The recovery procedure execution unit 600 is configured: when the determination unit 400 determines that the UE has performed the power reduction procedure, and when the determination unit 400 determines that the network configuration parameter of the UE is not less than the set threshold value, performing the UE recovery procedure. Thus, the user equipment (UE) power reduction hardware system can determine, based on the network configuration parameter of the UE, which is obtained by the obtaining module 300, whether the Internet speed of the UE is limited, to determine whether the power reduction procedure execution module 500 performs the power reduction procedure of the UE, to effectively reduce the power consumption of the UE, extend the UE latency, and improve the user experience.

[0024] In an exemplary implementation of the second aspect of the present invention, when the UE is in the 5G NSA network mode, the network configuration parameter of the UE includes an Access Point Identifier - Aggregated Maximum Transfer Rate (APN-AMBR) parameter, where APN-AMBR is an upper limit the sum of the rates of all non-guaranteed rate (non-GBR) bearers for an Access Point Identifier (APN), with the APN-specific APN-AMBR being used as the subscription parameter of each APN to limit the aggregate rate of all PDN connections in the same APN, and the value of the APN-AMBR parameter may indicate the Internet speed allocated by the network operator to the UE; or when the UE is in 5G SA network mode, the network configuration parameter of the UE includes a per-session aggregated maximum transmission rate (Session-AMBR) parameter, wherein the Session-AMBR specifies an upper limit on the sum of the transmission rates of all Quality of Service (QoS) flows with no- GBR for the session PDU, and the value of the Session-AMBR parameter may represent the Internet speed allocated by the network operator to the UE. Thus, the network configuration parameter of the UE can be used to determine whether the Internet speed of the UE is limited, so that the power reduction hardware system of the user equipment (UE) determines whether to perform the power reduction procedure.

[0025] In an exemplary implementation of the second aspect of the present invention, a method for determining by the determining module 400 whether the network configuration parameter of the UE is less than the set threshold includes: when the UE is in the 5G NSA network mode, the determining module 400 determines whether the uplink rate in the APN-AMBR parameter is less than the set first threshold value, and/or the determination module 400 determines whether the downlink rate in the APN-AMBR parameter is less than the set second threshold value; or when the UE is in the 5G SA network mode, the determination module 400 determines whether the uplink rate in the Session-AMBR parameter is lower than the set third threshold value, and/or the determination module 400 determines whether the downlink rate in the Session parameter is lower -AMBR than the fourth threshold set. Thus, the user equipment (UE) power reduction hardware system can determine whether the UE's Internet speed is limited to determine whether to perform the power reduction procedure.

[0026] In an exemplary implementation of the second aspect of the present invention, a method for performing a power reduction procedure on a UE by the power reduction procedure execution unit 500 includes methods and steps for performing a power reduction on a UE according to possible implementations of the first aspect of the present invention. Thus, the hardware system for reducing the power consumption of the user equipment (UE) can effectively reduce the power consumption of the UE and extend the waiting time of the UE, thereby improving the user experience.

[0027] In an exemplary implementation of the second aspect of the present invention, before the determination module 400 determines whether the UE network configuration parameter is less than the set threshold, setting the threshold is further included, and a method for setting the set threshold includes the following: The acquisition module 300 uses the first value input by the user as the set threshold value; or the obtaining unit 300 sets the value of the network configuration parameter of the UE, which is obtained when the Internet speed of the UE is not limited, as the set threshold value. Thus, the set threshold can be used as a metric for determining whether the UE's Internet speed is limited, so that the user equipment (UE) power reduction hardware system determines whether to perform the power reduction procedure.

[0028] In an exemplary implementation of the second aspect of the present invention, a method for performing the recovery procedure of the UE by the recovery procedure execution unit 600 includes: the operating state of the UE before the power reduction procedure execution unit 500 performs the power reduction procedure of the UE is the first operation state, the operation the state of the UE after the power reduction procedure execution unit 500 performs the UE power reduction procedure is the second operating state, and that the recovery procedure execution unit 600 performs the recovery procedure of the UE indicates a process in which the UE transitions from the second operation state to the first working condition. Thus, the hardware system for reducing the power consumption of the user equipment (UE) can start the recovery procedure of the UE based on the actual situation, so that the UE reaches an optimal operating state.

DESCRIPTION OF EMBODIMENTS

[0052] The following describes in detail the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0053] The problem to be solved in the present invention is to provide a method and a hardware system for reducing the power consumption of a UE, so as to effectively reduce the power consumption of the UE, extend the UE latency, and improve the user experience.

[0054] In the implementation of the present invention, UE refers to an electronic device that has a data processing and calculation function and a wireless communication function. UE includes, but is not limited to: a smartphone (for example, an Android mobile phone, an iOS mobile phone (iPhone operating system), or a mobile phone running another operating system), a tablet computer, a PDA, a portable media player, an electronic photo frame , electronic game console, laptop computer, mobile Internet device (Mobile Internet Devices), wearable device (for example, smart watch, smart bracelet, smart glasses or head-mounted device (HMD)), smart home device, device Internet of things, smart car or similar.

[0055] Some specific UE types are listed above. However, those skilled in the art may be aware that the embodiments of the present invention are not limited to the types listed above, but can be further applied to any other types of electronic devices and any other types of operating systems.

[0056] In the descriptions of embodiments of the present invention, "/" means "or", unless otherwise indicated. For example, "A/B" may represent A or B. In this description, "and/or" only describes an association relation for describing related objects, and represents that three relations may exist. For example, "A and/or B" can represent the following three cases: Only A exists, both A and B exist, and only B exists. In addition, in the descriptions of embodiments of the present invention, "multiple" means two or more than two.

[0057] Embodiments of the present invention provide a method and a hardware system (device) for reducing the power consumption of a UE. It should be noted that the method and hardware system for reducing the power consumption of a UE is based on UEs in various 5G network modes. Since the UE may be connected to the base station or the core network in various ways, there are various operations to reduce power consumption. FIG. 1 is a schematic representation of 5G NSA and SA network modes according to an embodiment of the present invention. Section 10 shown in FIG. 1 is a representation of the 5G SA network mode, and the section 20 shown in FIG. 1 is a representation of NSA's 5G network mode. FIG. 1 only provides exemplary representations of 5G SA and NSA network modes, but there may be other forms of 5G SA and NSA network modes that are not limited to the content described in FIG. 1.

[0058] Embodiment 1 of the present invention provides a method for reducing the power consumption of a UE in a 5G NSA network mode.

[0059] FIG. 2 is a schematic block diagram of a flow of a method for reducing power consumption of a UE in a Non-Stand Alone (5G NSA) network mode according to an embodiment of the present invention. As shown in FIG. 2, the method may include:

[0060] S201. The UE receives the APN-AMBR (Access Point Name-Aggregate Maximum Bit Rate) parameter.

[0061] The 5G NSA standard uses a dual connection mode of LTE (Long Term Evolution, Long Term Evolution) and 5G NR (New Radio, New Radio Communication); and 4G is used as the control plane anchor point, a 4G base station (eNB) is a master station, a 5G base station (gNB) is a slave station, and a 4G core network is used. In the 5G NSA network mode, the procedure for setting up a session or the procedure for modifying a session is similar to that in LTE. Therefore, in this embodiment, a session establishment or modification process between a UE and a network side is described using a 4G PDN (Public Data Network) session modification or session establishment procedure. In the session modification or session establishment procedure of the 4G PDN, the UE side may obtain an APN-AMBR parameter to determine whether the UE's Internet speed is limited.

[0062] APN-AMBR (Access Point Name-Aggregate Maximum Bit Rate, access point identifier - aggregated maximum transmission rate) is an upper limit on the sum of the transmission rates of all non-GBR (Non Guaranteed Bit Rate) bearers for APN (Access Point Name, access point identifier), and APN-AMBR, which is specific to APN, is used as a subscription parameter of each APN to limit the aggregate transmission rate of all PDN connections in the same APN. That is, the APN-AMBR value may be used to reflect the Internet speed allocated by the network operator to the UE. The downlink APN-AMBR is performed by the P-GW (PDN GateWay, PDN Gateway), and the uplink APN-AMBR is performed by the UE and the P-GW. The APN-AMBR obtained in step S201 may include an uplink APN-AMBR and/or a downlink APN-AMBR.

[0063] FIG. 3 is a schematic block diagram of a 4G PDN session establishment process in 5G NSA network mode according to an embodiment of the present invention. As shown in FIG. 3, the method may include:

[0064] S301. The UE sends an attach request message to the network (to better describe this solution, the base station, the core network, and the like are collectively referred to as the network side, hereinafter referred to as the "network side").

[0065] S302. The network side sends an attach acceptance message to the UE. The Attach Accept message includes the APN-AMBR parameter.

[0066] S303. The UE sends a PDN session request to the network side to activate the PDN to receive a connection.

[0067] S304. The network side sends a default EPS (Evolved Packet System) bearer context activation request message to the UE, wherein the default EPS bearer context activation request message includes the APN-AMBR parameter.

[0068] S305. The UE sends a default EPS bearer context activation response message to the network side.

[0069] The method described in steps S301-S305 is based on the case in which the UE can activate the default APN during the join process when the power of the UE is turned on and the UE sends the network side a join request message and transfers the activation request PDN at the same time.

[0070] In another method in this embodiment, the APN-AMBR parameter may be obtained in a process in which the UE, after it has performed the join, performs an APN handoff or reactivates the APN. That is, the other method may only include step S303, step S304, and step S305, and the APN-AMBR parameter can be obtained from the EPS bearer context request message in step S304.

[0071] Both the join request message and the default EPS bearer context activation request message in the 4G PDN connection setup procedure include an APN-AMBR parameter, and the APN-AMBR parameter can be obtained in the previous two phases, to determine if the UE's Internet speed is limited.

[0072] FIG. 4 is a schematic block diagram of a 4G PDN session modification process in 5G NSA network mode according to an embodiment of the present invention. As shown in FIG. 4, the method may include:

[0073] S401. The network side sends an EPS bearer context modification request to the UE to initiate the PDN session modification process, that is, the PDN modification process is initiated by the network side. The EPS Bearer Context Modify Request message carries the APN-AMBR parameter. The APN-AMBR parameter may be used to determine if the UE's Internet speed is limited.

[0074] S402. The UE sends an EPS bearer context modification acceptance message to the network side.

[0075] In the 4G PDN session modification procedure, the APN-AMBR parameter may be obtained to determine whether the UE's Internet speed is limited.

[0076] S202. The UE determines if the APN-AMBR is less than the set threshold.

[0077] That is, it is determined whether the APN-AMBR value that is received by the UE is less than the set threshold value. The set threshold is a value used to indicate whether the UE's Internet speed is limited. For example, the Internet speed in a 5G package is 1 Gbps-4.5 Gbps (Gigabits per second, 1000 megabits per second), and the settable threshold can be set to 1 Gbps. When the value of APN-AMBR is less than 1 Gbps, it means that the UE's Internet speed is limited. In this embodiment, the threshold value may be set based on the actual scenario of the user. The value of the threshold value in the present invention is not limited.

[0078] Before the step of determining whether the APN-AMBR value that is received by the UE is less than the set threshold, setting the set threshold is also included. Methods for setting a settable threshold include:

[0079] Optional threshold setting method 1: UE uses the first value entered by the user as the set threshold: For example, a function menu bar is added to the UE system so that the user can independently select the threshold value in this menu bar. For example, the user may select a threshold value in the UE mobile network setup function menu, or the user may input the threshold value in the UE mobile network setup function dialog, or the user may set the threshold value in the UE voice assistant by voice input.

[0080] Optional threshold setting method 2: The UE sets the value of the UE network configuration parameter, which is obtained when the UE's Internet speed is not limited, to the threshold value to be set: For example, when the UE first registers in a 5G network, the UE can obtain the APN-AMBR parameter in the process of attaching, and the UE may set this APN-AMBR parameter to a threshold value.

[0081] The APN-AMBR parameter obtained by the UE includes an uplink rate value and a downlink rate value. A method for determining by the UE whether the APN-AMBR is less than a set threshold includes:

[0082] The UE determines if the uplink rate value in the APN-AMBR parameter that is received by the UE is less than the set first threshold value, for example, the uplink rate in the APN-AMBR parameter is less than 0.5 Gbps.

[0083] Alternatively, the UE determines whether the downlink rate value in the APN-AMBR parameter that is received by the UE is less than the set second threshold value, for example, the downlink rate in the APN-AMBR parameter is less than 1 Gbps. With.

[0084] Alternatively, the UE determines whether the value of the uplink rate in the APN-AMBR parameter, which is obtained by the UE, is less than the set third threshold value, and the UE determines whether the value of the downlink rate in the APN-AMBR parameter, which is less than received by the UE than the set fourth threshold, for example, the uplink rate in the APN-AMBR is less than 0.5 Gbps and the downlink rate in the APN-AMBR is less than 1 Gbps.

[0085] If the APN-AMBR is less than the set threshold, step S203 is performed: The UE starts a power reduction procedure. There may be many ways to reduce the power consumption of the UE. Methods for reducing UE power consumption include:

[0086] Method 1 for reducing UE power consumption: If the APN-AMBR parameter is less than the set threshold, the EN-DC (Eutra NR Dual Connectivity) capability of the UE is not directly disabled, but only does not measure the NR neighbor cell.

[0087] "DC" represents a double connection; "E" represents E-UTRA(N) (Enhanced Universal Terrestrial Radio Access (network)), i.e. 4G radio access network, and "N" represents 5G NR (New Radio). EN-DC (Eutra NR Dual Connectivity) refers to the dual connection of 4G and 5G NR radio access network. In the 5G network mode, the NSA UE connects to the 4G core network, the 4G base station is the master station, and the 5G base station is the secondary station. In this method, the dual connection function of the 4G UE and 5G NR radio access network is not directly disabled, but only realized that the UE no longer measures the NR neighbor cell and no longer responds to the action of adding an SCG (Secondary Cell Group) to the network; that is, the UE no longer adds 5G NR, and the UE only connects to the 4G network and does not connect to the NR network, thereby reducing the power consumption of the UE.

[0088] The implementation of method 1 for reducing the power consumption of a UE includes many options. A specific implementation includes the following options:

[0089] Option 1: FIG. 5 is a schematic representation of a method for triggering power reduction by a UE in 5G NSA network mode according to an embodiment of the present invention. As shown in FIG. 5, if the UE is currently in an RRC (Radio Resource Control) connection establishment state, the UE may send an SCG failure message (secondary cell group failure message) to the network side to prompt the base station to release the SCG. Moreover, in order to prevent the network side from re-adding the NR, the UE no longer measures the local NR neighbor cell and no longer responds to the network side measurement event B1. The meanings of specific events are given in Table 1.

Table 1

Event A1 The measured value (RSRP (Reference Signal Received Power) or RSRQ (Reference Signal Received Quality)) of the serving cell exceeds the threshold value. Event A2 The measured value (RSRP or RSRQ) of the serving cell is less than the threshold value. Event A3 The measured value of the neighbor cell is better than the measured value of the serving cell by a threshold value. Event A4 The measured neighbor cell value is greater than the threshold value. Event A5 The measured value of the serving cell is less than threshold 1 and the channel quality of the neighbor cell is greater than threshold 2. Event B1 The channel quality of the intertechnology neighbor cell is greater than the threshold value. Event B2 The channel quality of the serving cell is less than threshold 1, and the channel quality of the intertechnology cell is greater than threshold 2.

[0090] Option 2: FIG. 6 is a schematic representation of another method for triggering power reduction by a UE in 5G NSA network mode according to an embodiment of the present invention. As shown in FIG. 6, if the UE is currently in the RRC connection setup state, and the network side configures the measurement event A2, the UE can fake the measurement event A2 and send this event to the network side to report that the signal energy NR is the minimum value specified in the protocol, to prompt the base station to release the SCG. Moreover, in order to prevent the network side from re-adding the NR, the UE no longer measures the local NR neighbor cell and no longer responds to the network side measurement event B1.

[0091] Option 3: If the UE is currently in the RRC idle mode, the UE no longer measures the immediate neighbor cell NR and no longer responds to the network side measurement event B1.

[0092] By using the above method 1 to reduce the power consumption of the UE, the power consumption of the UE can be reduced.

[0093] The options listed in method 1 for reducing UE power consumption may affect the display of the 5G icon. Once the SCG is no longer added, the display of the 5G icon depends on the 5G icon display policy. FIG. 7A-FIG. 7E are schematic representations of a UE network standard icon display according to an embodiment of the present invention. FIG. 7A is a schematic representation of a display state of a 5G icon according to an embodiment of the present invention. As shown in FIG. 7A, the word "5G" indicated at 710 is a 5G icon, and the display state is a state in which the UE normally displays the 5G icon. The display state shown in this figure and 710 is just an example of displaying the 5G icon, and does not limit the display to the 5G icon. At present, the GSMA (Groupe Speciale Mobile Association) provides the following rules for displaying the 5G icon. The impact analysis is shown in Table 2.

table 2

Icon display scheme Conditions for displaying the 5G icon Fashion influence on 5G icon ConfigA The UE is in connected mode and the NR SCG is added. The 5G icon cannot be displayed. configB UE is in connected mode and NR SCG is added; or
The UE is in idle mode and an NR cell is detected. The 5G icon cannot be displayed. ConfigC UE is in connected mode and NR SCG is added; or
UE is in connected mode and no NR SCG is added, but NR is detected; or
The UE is in idle mode and an NR cell is detected. The 5G icon cannot be displayed. ConfigD The UE only needs to support NR and there is no need to consider whether the UE detects NR or whether the NR is in connected mode. The 5G icon can be displayed.

[0094] The beneficial effect of the method is as follows: According to the rule in the icon display scheme ConfigD, this method does not affect the display of the 5G UE icon and does not degrade the user experience. However, according to other rules, the UE cannot display the 5G icon, and the display states of the network standard icon of the UE may include the states shown in the schematic diagrams shown in FIG. 7B-FIG. 7B. That is, the UE may display the "4G" icon indicated at 720; or the UE may display the "3G" icon indicated at 730; or the UE may display the "CDMA" icon indicated at 740; or, as indicated at 750, the UE may not display any network standard icon.

[0095] Method 2 for reducing UE power consumption: If the APN-AMBR parameter is less than the set threshold value, the EN-DC capability of the UE is directly disabled.

[0096] FIG. 8 is a schematic representation of another method for triggering power reduction by a UE in 5G NSA network mode according to an embodiment of the present invention. FIG. 8 describes the contents of method 2 for reducing power consumption of a UE, and this method mainly includes the following steps:

[0097] S801. Performing an RRC connection setup procedure between the network side and the UE side.

[0098] S802. The UE sends TAU (Tracking Area Update) signaling.

[0099] S803. The network side releases the RRC connection of said UE.

[00100] The TAU signaling sent by the UE to the network side carries the IE field, and the IE field can be used to disable the EN-DC capability of said UE.

[00101] It should be noted that when the UE is in the RRC connected mode, it is only necessary to enable step 802 to implement method 2 to reduce the power consumption of the UE; or when the UE is in the RRC idle mode, it is necessary to include step S801, step S802, and step S803 to implement this method.

[00102] In Method 2 above, in order to reduce the power consumption of the UE, the EN-DC capability of the UE may be completely disabled to reduce the power consumption of the UE.

[00103] However, it should be noted that in method 2 for reducing the power consumption of the UE, the display of the 5G icon on the UE is affected. In this embodiment of the present invention, the UE may provide a proper prompt to ensure that the user is notified so that the user is not confused by not being able to display the 5G icon. The hint method may include:

[00104] A dialog box is displayed on the UE screen to notify the user that since the UE's Internet speed is limited, the 5G disable function will be enabled to reduce power consumption, the 5G icon will disappear, and a different network standard icon will be displayed; and the user can decide whether to agree to the operation to reduce power consumption, and the user is given a choice to confirm or reject in the dialog box; or

a dialog box is displayed on the UE screen and the user is notified with a voice prompt that, since the UE's Internet speed is limited, the 5G disable function will be enabled to reduce power consumption, the 5G icon will disappear, and a different network standard icon will be displayed; and the user can decide whether to agree to the operation to reduce power consumption, and the user is given a choice to confirm or reject in the dialog box; or

The UE may not provide any hint.

[00105] Method 3 for reducing power consumption of the UE: If the APN-AMBR parameter is less than the set threshold value, the millimeter wave function of the UE is directly disabled.

[00106] According to 3GPP 38.101, 5G NR mainly uses two frequencies: FR1 frequency band and FR2 frequency band. The frequency range of the FR1 frequency band is 450MHz-6GHz, also referred to as sub-6GHz. The frequency range of the FR2 frequency band is 24.25GHz-52.6GHz, that is, millimeter wave (mmWave). Since the millimeter wave function exists only in NR, and the power consumption is high, if the UE supports millimeter wave, the millimeter wave function can be directly disabled.

[00107] In the above method 3, in order to reduce the power consumption of the UE, the millimeter wave function of the UE may be completely disabled to reduce the power consumption of the UE.

[00108] Method 4 for reducing UE power consumption: If the APN-AMBR is less than the set threshold, the UE retains the EN-DC capability, but other UE capabilities are reduced.

[00109] Compared to LTE, NR still has some other advantages such as relatively low latency and large user throughput. In this method embodiment, the UE may still retain the EN-DC capability, but other UE capabilities may be reduced to minimize the UE's power consumption while providing a better user experience. Options for reducing other UE capabilities include the following:

[00110] Option 1: The 3GPP protocol (hereinafter referred to as "protocol") only requires that the number of antennas supported by the UE in the LTE operating band be 1T2R, that is, the downlink requirement is at least 2*2 MIMO ( Multi-input Multi-output, multiple inputs, multiple outputs). In this case, the UE may disable the 4*4 MIMO configuration capability and enable only 2*2 MIMO to reduce antenna resource overhead and reduce power consumption.

[00111] Option 2: With regard to NR operating bands, said protocol only requires support for 4*4 MIMO configuration capability in bands n7, n38, n41, n77, n78 and n79. There is no such requirement in the other operating frequency band. The UE may disable the 4*4 MIMO configuration capability in a different operating frequency band to reduce antenna resource overhead and reduce power consumption.

[00112] Option 3: The UE may disable the NR-CA function to reduce power consumption. CA (Carrier Aggregation, carrier aggregation) for aggregating multiple carriers for data transmission. Since the frequency band available to each operator is limited and may not be continuous, if each UE can only use a few frequency bands, the UE's rate will be limited. The CA technology is for aggregating spectrum resources of the same frequency band or different frequency bands for use by a UE in order to increase the speed of the UE. In this embodiment, the NR-CA function is disabled to reduce power consumption.

[00113] Option 4: In the NSA scenario, the UE supports CA capability in both LTE and NR, i.e. both LTE and NR support Multiple-CC (Component Carrier) capability. In this scenario, the capabilities of the UE in LTE and NR can be adapted, that is, the UE side only informs the network side of the LTE single CC capability and the NR single CC capability to reduce the power consumption of the UE.

[00114] Option 5: The UE may disable HPUE (High-Power User Equipment) capability in all operating frequency bands so that only 23 dBm capability and 26 dBm capability are supported in these operating frequency bands. The UE is limited to transmitting with a maximum output power of 23 dBm, so that the power of the UE can be reduced effectively.

[00115] Option 6: The UE may disable the TDM (Time Division Multiplexing) capability for the uplink transmit power of LTE and NR so that the UE supports only 20 dBm, not 23 dBm as in LTE, so and in NR. Thus, the power overhead for the uplink of the UE can be reduced.

[00116] All of the mentioned options in method 4 to reduce the power consumption of the UE should be implemented by re-messaging the UE capabilities by the UE. In particular, the network side can be notified of the capabilities of the UE by using the TAU or the reattach method to effectively reduce the power consumption of the UE.

[00117] Method 5 for reducing UE power consumption: If the APN-AMBR is less than the set threshold, the EN-DC capability of the UE is disabled, and when the UE provides a service in LTE mode, the UE's capability is further restricted.

[00118] In method 5, to reduce the power consumption of the UE, the EN-DC capability of the UE is directly disabled, and when the UE provides a service in LTE, the capabilities of the UE are further restricted so that the UE complies with the rate limit provided by the current network (for example, the rate limit is reduced to Category 4) . Referring to Table 3 (only the low-rate categories defined by 3GPP are listed), among the categories in LTE that are defined in the protocol, a lower corresponding LTE CAT can be selected based on the rate limit, that is, the rate level that can be supported by the UE, so that reduce energy consumption.

Table 3

Category Speed Limit Notes Category 4 Downlink: 150 Mbps; uplink: 50 Mbps. Downlink: 1 CC; uplink: 1 CC. Category 5 Downlink: 300 Mbps; uplink: 75 Mbps. Downlink: 2 CC; uplink: 1 CC. Category 6 Downlink: 300 Mbps; uplink: 50 Mbps. Downlink: 2 CC; uplink: 1 CC.

[00119] Method 5 for reducing the power consumption of the UE should be implemented by re-messaging the UE capabilities by the UE. In particular, the network side can be notified of the capabilities of the UE by using TAU signaling or a reattachment method to effectively reduce the power consumption of the UE.

[00120] In this method, in order to reduce the power consumption of the UE, it is also necessary to consider the processing of non-standard scenarios such as UE restart, flight mode enabled by the UE, and modem restart. From a power reduction point of view, the UE needs to ensure that when these scenarios occur, the UE can still maintain the effectiveness of the previous power reduction measures. It should be noted that the UE power reduction procedure in this embodiment of the present invention may be one of the above methods or any combination of the above methods, which is not limited in this embodiment of the present invention.

[00121] If the APN-AMBR is greater than or equal to the set threshold, step S204 is performed: The UE determines whether a power reduction procedure has been performed. If the UE has not performed the power reduction procedure, the procedure is terminated immediately without changing the operating state of the UE.

[00122] If the APN-AMBR is greater than or equal to the set threshold and the UE has performed the power down procedure, step S205 is performed: the UE starts the recovery procedure. The operation state of the UE before the UE starts the power reduction procedure is the first operation state, the operation state of the UE after the UE starts the power reduction procedure is the second operation state, and that the UE starts the recovery procedure indicates the process in which the operating state of the UE is changed from the second operating state to the first operating state. The method for the recovery procedure includes:

[00123] Recovery procedure method 1: If the APN-AMBR parameter is not less than the set threshold and the UE has performed the power reduction procedure, the UE is again enabled to locally measure the NR neighbor cell to restore the standard protocol procedure.

[00124] FIG. 9 is a schematic representation of a method for starting a recovery procedure by a UE in a 5G NSA network mode according to an embodiment of the present invention.

[00125] S901. The network side requests the UE to measure the neighbor cell NR and report the measurement event B1.

[00126] S902. The UE responds to the measurement event B1, and the UE locally starts the NR neighbor cell measurement that was requested and reports the event B1 to the network side.

[00127] S903. The UE network adds the SCG.

[00128] In method 1, for the recovery procedure, the UE may re-enable the ability to locally measure the NR neighbor cell in order to restore the normal operating state of the UE.

[00129] Recovery procedure method 2: If the APN-AMBR is not less than the set threshold and the UE has performed the power down procedure, the EN-DC capability for the UE is re-enabled.

[00130] Referring to FIG. 8, the UE recovery procedure is similar to that shown in FIG. 8. However, in step S802, the UE sends the TAU to the network side, and the TAU carries the IE field used to re-enable the EN-DC capability for the UE.

[00131] In method 2 for the recovery procedure, the UE may re-enable the EN-DC capability to restore the normal operating state of the UE.

[00132] Recovery procedure method 3: If the APN-AMBR parameter is not less than the set threshold value and the UE has performed the power reduction procedure, the millimeter wave function for the UE is turned on again.

[00133] In method 3 for the recovery procedure, the millimeter wave function of the UE may be re-enabled to restore the normal operating state of the UE.

[00134] Method 4 for recovery procedure: If the APN-AMBR parameter is not less than the set threshold value and the UE has performed the power down procedure, the UE's capabilities are restored. To inform the UE capabilities again, the UE may notify the network side of the new UE capabilities by sending a TAU to the network side or by using a reattach method to restore the original working state of the UE.

[00135] In method 4 for the recovery procedure, the UE's capabilities may be restored to restore the normal operating state of the UE.

[00136] Method 5 for recovery procedure: If the APN-AMBR parameter is not less than the set threshold value and the UE has performed the power reduction procedure to inform the UE capabilities again, the UE may notify the network side of the new UE capabilities by sending a TAU to the network side or by using the reattach method to restore the original working state of the UE.

[00137] In method 5, for the recovery procedure, the UE's capabilities may be restored to restore the normal operating state of the UE.

[00138] It should be noted that in this embodiment, the NSA 5G network mode recovery procedure should be one-to-one with the power reduction procedure.

[00139] The beneficial effect of Embodiment 1 of the present invention is as follows: After it is determined whether the APN-AMBR parameter obtained by the UE is less than the set threshold, and it is found that the Internet speed of the UE is limited, measures that can be taken by the UE to reduce power consumption include: the UE actively releases the SCG, disables the EN-DC capability, disables the UE's millimeter wave function, and reduces other capabilities of the UE (the specific method includes disabling CA, disabling antenna diversity, and downgrading LTE). Therefore, the power consumption of the UE can be significantly reduced, and the waiting time of the user equipment is increased, and the user experience is improved. When the user pays the obligation or the operator resumes service to the user at the beginning of the month, the Session-AMBR obtained by the UE will not be less than the set threshold, and a recovery procedure is started to restore the normal working state of the UE network

[00140] Embodiment 2 of the present invention provides a method for reducing the power consumption of a UE in a 5G SA network mode.

[00141] FIG. 10 is a schematic representation of a flow of reducing power consumption of a UE in a 5G SA network mode according to an embodiment of the present invention. In Embodiment 2 of the present invention, a method for reducing power consumption of a UE in a 5G SA network mode includes:

[00142] S1001. The UE receives a Session-AMBR (per Session-Aggregate Maximum Bit Rate) parameter.

[00143] Similar to the nature of APN-AMBR in LTE, Session-AMBR is an upper bound on the sum of the rates of all Quality of Service (QoS) flows with non-GBR for a Protocol Data Unit (PDU) session, and Session-AMBR can also be used to reflecting the Internet speed allocated by the network service provider to the UE. During the 5G PDU session establishment process or session modification process, the UE may receive Session-AMBR on the network side.

[00144] FIG. 11 is a schematic representation of a 5G PDU session establishment process in a 5G SA network mode according to an embodiment of the present invention. Unlike the PDN session establishment in LTE, the registration procedure and the PDU session establishment procedure in 5G are separated.

[00145] The method shown in FIG. 11, includes: S1101. The UE sends a registration request to the network side;

[00146] S1102. The network side sends registration acceptance signaling to the UE.

[00147] S1103. The UE sends signaling to the network side to set up a session PDU.

[00148] S1104. The network side sends the PDU session setup accept signaling to the UE, wherein the PDU session setup accept signaling carries the Session-AMBR parameter. In this process, the Session-AMBR parameter received by the UE may be used to determine whether the UE's Internet speed is limited.

[00149] FIG. 12 is a schematic representation of a 5G PDU session modification process in 5G SA network mode according to an embodiment of the present invention.

[00150] The PDU session modification process may be initiated by the UE. The method shown in FIG. 12 includes: S1201: The UE sends a session PDU modification request to the network side; step S1202: The network side sends a PDU session modification command to the UE; and S1203: The UE sends a session PDU modification completion message to the network side. The entire PDU session modification process is completed. The PDU session modification command sent by the network side to the UE carries the Session-AMBR parameter. In this process, the Session-AMBR parameter received by the UE may be used to determine whether the UE's Internet speed is limited.

[00151] FIG. 13 is a schematic representation of another 5G PDU session modification process in 5G SA network mode according to an embodiment of the present invention.

[00152] The PDU session modification process may alternatively be initiated by the network side. The method shown in FIG. 13 includes: step S1301: The network side sends a PDU session modification command to the UE; and S1302: The UE sends a PDU modification completion message to the network side. The PDU session modification command sent by the network side to the UE carries the Session-AMBR parameter. In this process, the Session-AMBR parameter received by the UE may be used to determine whether the UE's Internet speed is limited.

[00153] S1002. The UE determines if the Session-AMBR is less than the set threshold.

[00154] The UE determines whether the Session-AMBR value that is obtained by the UE is less than the set threshold, where the set threshold is a value used to indicate whether the UE's Internet speed is limited. For example, the Internet speed in a 5G package is 1 Gbps-4.5 Gbps, and the settable threshold can be set to 1 Gbps. When the Session-AMBR value is less than 1 Gbps, it means that the UE's Internet speed is limited. In this embodiment, the threshold value may be set based on the actual scenario of the user. The value of the threshold value in the present invention is not limited.

[00155] Before the step of determining whether the Session-AMBR value that is received by the UE is less than the set threshold, setting the set threshold is further included. Methods for setting a settable threshold include:

[00156] Optional threshold setting method 1: UE uses the first value entered by the user as the set threshold: For example, a function menu bar is added to the UE system so that the user can independently select the threshold value in this menu bar. For example, the user may select a threshold value in the UE mobile network setup function menu, or the user may input the threshold value in the UE mobile network setup function dialog, or the user may set the threshold value in the UE voice assistant by voice input.

[00157] Optional threshold setting method 2: The UE sets the value of the UE network configuration parameter, which is obtained when the UE's Internet speed is not limited, to the threshold value to be set: For example, when the UE first registers in a 5G network, the UE may obtain the Session-AMBR parameter in the join process, and the UE may set this Session-AMBR parameter to a threshold value.

[00158] The Session-AMBR received by the UE includes an uplink rate value and a downlink rate value. A method for determining by the UE whether the Session-AMBR is less than a set threshold includes:

[00159] The UE determines whether the value of the uplink rate in the Session-AMBR parameter that is received by the UE is less than the set first threshold value, for example, the uplink rate in the Session-AMBR parameter is less than 0.5 Gbps.

[00160] Alternatively, the UE determines whether the value of the downlink rate in the Session-AMBR parameter that is received by the UE is less than the set second threshold value, for example, the downlink rate in the Session-AMBR parameter is less than 1 Gbps. With.

[00161] Alternatively, the UE determines whether the value of the uplink rate in the Session-AMBR parameter, which is obtained by the UE, is less than the set third threshold value, and the UE determines whether the value of the downlink rate in the Session-AMBR parameter, which is less than received by the UE than the set fourth threshold, eg, the uplink rate in the Session-AMBR is less than 0.5 Gbps and the downlink rate in the Session-AMBR is less than 1 Gbps.

[00162] If the Session-AMBR is less than the set threshold, step 1003 is performed: The UE starts a power down procedure. There may be many ways to reduce the power consumption of the UE. Methods for reducing UE power consumption include:

[00163] Method 1 for reducing UE power consumption: If the Session-AMBR is less than the set threshold value, the millimeter wave function of the UE is directly turned off.

[00164] According to 3GPP 38.101, 5G NR mainly uses two frequencies: FR1 frequency band and FR2 frequency band. The frequency range of the FR1 frequency band is 450MHz-6GHz, also referred to as sub-6GHz. The frequency range of the FR2 frequency band is 24.25GHz-52.6GHz, that is, millimeter wave (mmWave). Since the millimeter wave function exists only in NR, and the power consumption is high, if the UE supports millimeter wave, the millimeter wave function can be directly disabled.

[00165] In the above method 1, in order to reduce the power consumption of the UE, the millimeter wave function of the UE may be completely disabled in order to reduce the power consumption of the UE.

[00166] Method 2 for reducing UE power consumption: If the Session-AMBR is less than the set threshold, the UE continues camping in NR, but other capabilities of the UE are reduced.

[00167] Compared to LTE, NR still has some other advantages such as relatively low latency and large user throughput. In this method, the UE may continue camping in NR, but other capabilities of the UE may be reduced to minimize power consumption while still providing a relatively low bit rate experience. Specific options for reducing other UE capabilities include:

[00168] Option 1: With regard to NR operating bands, said protocol only requires support for 4*4 MIMO configuration capability in bands n7, n38, n41, n77, n78 and n79. There is no such requirement in the other operating frequency band. The UE may disable the 4*4 MIMO configuration capability in a different operating frequency band to reduce antenna resource overhead and reduce power consumption.

[00169] Option 2: The UE may disable the NR CA function to reduce power consumption.

[00170] Option 3: The UE may disable the HPUE capability in all operating frequency bands so that only 23 dBm capability and 26 dBm capability are supported in these operating frequency bands.

[00171] All of these options in the above method to reduce the power consumption of the UE should be implemented by re-messaging the UE capabilities by the UE. Specifically, the UE may notify the network side of the UE's capabilities by sending a TAU to the network side or using a re-registration method to effectively reduce the power consumption of the UE.

[00172] Method 3 for reducing UE power consumption: If the Session-AMBR is less than the set threshold, the UE uses less resources.

[00173] FIG. 14 is a schematic representation of another method for triggering power reduction by a UE in a 5G SA network mode according to an embodiment of the present invention. As shown in FIG. 14, after each RRC connection is established, the UE may alternatively notify the network side with a UE side message that fewer CCs are used by the UE, fewer MIMO layers are used by the UE, or lower aggregated throughput is used by the UE. U.E.

[00174] The above method for reducing the power consumption of the UE can enable the UE to use fewer resources, thereby reducing the power consumption of the UE.

[00175] If the Session-AMBR is not less than or equal to the set threshold, step S1004 is performed: The UE determines whether the UE has performed the power reduction procedure. If the UE has not performed the power reduction procedure, the procedure is terminated immediately without changing the operating state of the UE.

[00176] If the Session-AMBR is greater than or equal to the set threshold and the UE has performed the power reduction procedure, step S1005 is performed: the UE starts the recovery procedure. The operation state of the UE before the UE starts the power reduction procedure is the first operation state, the operation state of the UE after the UE starts the power reduction procedure is the second operation state, and that the UE starts the recovery procedure indicates the process in which the operating state of the UE is changed from the second operating state to the first operating state. The method for the recovery procedure includes:

[00177] Recovery procedure method 1: If the Session-AMBR is not less than the set threshold and the UE has performed the power reduction procedure, the millimeter wave function for the UE is turned on again.

[00178] Method 2 for recovery procedure: If the Session-AMBR is not less than the set threshold and the UE has performed the power down procedure, the UE's capabilities are restored. Specific options for restoring UE capabilities include:

[00179] Option 1: The UE may re-enable the 4*4 MIMO configuration capability in all operating frequency bands.

[00180] Option 2: The UE may re-enable the NR CA function.

[00181] Option 3: The UE may re-enable the HPUE capability in all operating frequency bands to restore the 26 dBm capability.

[00182] All of these options in the above method must be implemented by re-messaging the UE capabilities by the UE. Specifically, the UE can notify the network side of the UE's capabilities by sending a TAU to the network side or using a re-registration method to effectively restore the UE's capabilities.

[00183] Method 3: If the Session-AMBR is not less than the set threshold and the UE has performed the power down procedure, the resources used by the UE are recovered.

[00184] After each RRC connection is established, the UE may notify the network side by using a UE help message to instruct the UE to use the normal CC, the UE to use the normal MIMO layer, or the UE to use the normal aggregated bandwidth.

[00185] It should be noted that in this embodiment, the 5G SA network mode recovery procedure should be one-to-one with the power reduction procedure.

[00186] The beneficial effect of Embodiment 2 of the present invention is as follows: After it is determined whether the Session-AMBR received by the UE is less than the set threshold, and it is found that the Internet speed of the UE is limited, measures that can be taken by the UE to reduce power consumption include turning off the millimeter wave function of the UE and reducing other capabilities of the UE (a specific method includes turning off the CA, turning off antenna diversity, and downgrading LTE). Therefore, the power consumption of the UE can be significantly reduced, and the waiting time of the user equipment is increased, and the user experience is improved. When the user pays the obligation or the operator resumes service to the user at the beginning of the month, the operator resumes service to the user, the Session-AMBR obtained by the UE is not less than the set threshold, and a recovery procedure is started to restore the normal working state of the UE network.
