The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0174] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0175] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary.

[0176] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0177] In some embodiments, MICO is introduced into NR (New Radio) to improve the UE's energy efficiency. The UE carries whether it supports MICO mode (i.e., MICO preference) in the initial registration or registration update message. Then, the AMF (Authentication Management Function) network element, based on the UE's indication, locally configures the UE registration information and network policies to determine the MICO mode and carries an indication in the registration message whether the UE is allowed to use MICO mode. If the network side supports the UE's MICO mode, the UE can deactivate AS (Access Stratum), activate MICO mode, and enter the 5GMM (5GS Mobility Management) - REGISTERED, NO-CELL-AVAILABLE state. The AMF network element will reject any downlink data transmission requests. The UE can exit MICO mode as needed, such as when uplink data arrives or during periodic location updates. MICO is only used for UEs in RRC-IDLE (idle) state, and not for UEs in RRC-INACTIVE (low power) state.

[0178] In some embodiments, the energy-saving mode applicable in the UE may include at least one of the following:

[0179] PSM (Power Saving Mode): PSM introduced in LTE (Long Term Evolution, 3GPP Long Term Evolution) uses the same power-saving principle in terminals as the MICO mode mentioned above.

[0180] Paging-DRX (Discontinuous Reception): Based on paging DRX, the UE can listen to paging intermittently, thus saving terminal power.

[0181] eDRX: By configuring a long DRXcycle, the terminal can listen for paging for a longer period of time, thereby achieving the purpose of saving energy in the terminal.

[0182] PEI (Paging Early Indication): The UE listens to the low-power signal PEI to determine whether it needs to wake up to listen for paging. If not, it does not listen for paging, thus achieving energy saving in the terminal.

[0183] TRS (Tracking Reference Signal) for paging: By configuring TRS, the terminal can achieve fast synchronization and avoid the long synchronization time caused by SSB (Synchronization Signal and PBCH (Physical Broadcast Channel) block) synchronization to receive paging, thus achieving the purpose of saving energy in the terminal.

[0184] LP-WUS (Low Power Wake Up Signal): This signal uses a low-power module to monitor whether the device needs to wake up to listen for paging. If not, it does not listen for paging, thus saving power for the terminal. The principle is similar to PEI.

[0185] In some embodiments, IoT (Internet of Things) devices have a significant need for power saving. Currently, there are various methods for network energy saving, but the network side cannot flexibly modify the energy-saving mode according to service requirements, especially during the transition of the UE from DRX mode to MICO mode. Therefore, there is no way to flexibly switch energy-saving modes to achieve the goal of power saving. Therefore, the purpose of this embodiment is to further improve the energy-saving performance of IoT devices. The network side dynamically changes the energy-saving mode and / or energy-saving configuration based on service distribution information, enabling IoT devices to achieve maximum energy savings.

[0186] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0187] Step S2101: The first network device 102 obtains the first information.

[0188] In some embodiments, the first information is used to indicate the service distribution of the terminal. The service distribution of the terminal refers to the geographical, temporal, and service type distribution of the terminal's use of various services (e.g., data, voice, video, etc.) in the network. The service distribution may include at least the following aspects:

[0189] Geographical distribution: The usage of services by terminals in different geographical locations. For example, some areas may primarily use high-bandwidth video services, while other areas may primarily use low-bandwidth IoT services;

[0190] Time distribution: The usage of services on the terminal at different times. For example, during the daytime on weekdays, business-related services may be the main activity, while on weekends, entertainment-related services may be the main activity.

[0191] Service type distribution: The frequency and traffic distribution of terminal usage of different service types. For example, voice services, data services, video services, IoT services (such as sensor data transmission), etc.

[0192] User behavior distribution: End-user usage habits and behavioral patterns. For example, some users may frequently use social media, while others may primarily use navigation apps.

[0193] For example, the first network device determines the applicable energy-saving strategy for the terminal by obtaining the service distribution information of the terminal. The first network device can be an access network device or a core network device; the method of obtaining the first information differs depending on the type of the first network device.

[0194] For example, when the first network device is a core network device, it can obtain primary information through multiple network elements in the core network. For instance, the AMF (Authentication Management Function) network element can track the location and status of terminals, providing access and mobility information; the SMF (Service Management Function) network element manages PDU (Packet Data Unit) sessions, providing terminal service traffic and QoS (Quality of Service) information; the UPF (User Port Function) network element processes user data forwarding, providing terminal traffic distribution and service types; and the PCF (Policy Control Function) network element provides service, QoS, and traffic policy information through policy management. The NWDAF (Network Data Analytics Function) network element is used to collect and analyze network device data, including user behavior, network element load, service experience, and network performance. The first network device can obtain terminal service requests and applicable conditions by analyzing signaling data between itself and various network elements.

[0195] Optionally, network slicing can allocate independent or shared network resources based on different service needs. By analyzing traffic and resource usage within slices, the primary network device can understand the distribution and demands of different services. The primary network device can also perform big data analysis using data from the core network and access network to understand the service distribution and clearing of terminals. Intelligent scheduling strategies can dynamically adjust resource allocation based on service needs and network status. By analyzing the execution results of the scheduling strategies, the primary network device can understand the distribution and demands of services.

[0196] In some embodiments, terminal 101 sends first information to first network device 102.

[0197] For example, the terminal provides its service distribution information to the first network device through a reporting mechanism.

[0198] In some embodiments, the first network device 102 processes the information to obtain the first information, in which case step S2101 is omitted.

[0199] In some embodiments, the first network device 102 obtains first information from the upper layer(s).

[0200] In this embodiment, the method by which the first network device obtains the first information is not limited. Different methods can be used to obtain the first information depending on the device type of the first network device and the current network environment requirements.

[0201] In some embodiments, the name of the first information is not limited, and it may be, for example, "business distribution information", "business data information", "business distribution status", etc.

[0202] Optionally, in some embodiments, the first information includes at least one of the following:

[0203] Arrival time distribution of business data units;

[0204] The time interval between business data units;

[0205] The time it takes for business data units to arrive;

[0206] The amount of data in a business data unit.

[0207] For example, in this embodiment, the first information is used to indicate the service distribution of the terminal. The first network device can analyze the first information to determine the applicable energy-saving strategy for the terminal based on the service distribution, thereby improving the energy-saving performance of the terminal. The first information may include at least one of the following:

[0208] The arrival time distribution of the service data unit is a probability distribution of the time intervals in which the service data units arrive in the terminal.

[0209] The time interval between business data units refers to the time difference between the arrival of two adjacent data units in the terminal.

[0210] The arrival time of the service data unit refers to the duration of a single service session in the terminal.

[0211] The data volume of a business data unit refers to the number of bytes in a single business data unit in the terminal.

[0212] Optionally, in some embodiments, before step S2101 above, the method further includes:

[0213] The first network device receives the fourth message sent by the second network device;

[0214] The first network device sends the fourth information to the terminal.

[0215] In some embodiments, the fourth information is used to indicate changes to the terminal's energy-saving strategy.

[0216] For example, in this embodiment, the second network device sends fourth information to the first network device to instruct the first network device to change the terminal's energy-saving strategy. This triggers the first network device to determine the first energy-saving strategy currently applicable to the terminal based on the first information, and then sends the fourth information to the terminal to instruct it to change the terminal's energy-saving strategy.

[0217] Optionally, in some embodiments, the fourth information includes at least one of the following:

[0218] Paging reason information is used to indicate a change in the terminal's energy-saving mode;

[0219] Energy-saving strategy update information.

[0220] For example, when the second network device determines that the terminal's energy-saving policy needs to be changed, it sends a paging message to the first network device. The paging message carries fourth information, which indicates that the paging reason is a change in the terminal's energy-saving mode or an update of the terminal's energy-saving policy information.

[0221] In step S2102, the first network device 102 determines the first energy-saving strategy of the terminal 101 based on the first information.

[0222] For example, the first network device analyzes the current energy-saving strategy applicable to the terminal based on the first information. If it determines that the current energy-saving strategy is not applicable, it determines the current applicable energy-saving strategy based on the first information. For instance, if the first network device analyzes the first information and determines that the terminal currently only has uplink services, it determines that the current applicable energy-saving mode is MICO mode, thereby switching the terminal from the current DRX state to the MICO state.

[0223] It should be noted that in this embodiment, the energy-saving strategy can be an energy-saving mode. The first network device determines the first energy-saving mode currently applicable to the terminal based on the first information, and instructs the terminal to switch from the currently running second energy-saving mode to the first energy-saving mode according to the first energy-saving strategy. For example, the terminal switches from the currently running DRX state to the eDRX state according to the first energy-saving strategy. Optionally, the energy-saving strategy can also be different configurations under the first energy-saving mode. The terminal adjusts the configuration parameters in the currently running first energy-saving mode according to the first energy-saving strategy. For example, if the terminal's currently running first energy-saving mode is DRX, and the first energy-saving strategy indicates different periodic configurations under DRX, then the terminal performs the switching between DRX periodic configurations under the DRX state according to the first information.

[0224] In step S2103, the first network device 102 sends the second information to the terminal 101 according to the first energy-saving strategy.

[0225] In some embodiments, the second information is used to instruct the terminal to change from the second energy-saving strategy to the first energy-saving strategy.

[0226] In some embodiments, the name of the second information is not limited, and it may be, for example, "energy-saving strategy change instruction information" or "energy-saving strategy switching information".

[0227] In some embodiments, terminal 101 receives second information.

[0228] For example, the second energy-saving strategy is the energy-saving strategy currently running on the terminal. After receiving the second information, the terminal switches the currently running energy-saving strategy from the second energy-saving strategy to the first energy-saving strategy.

[0229] It should be noted that in this embodiment, the relationship between the energy loss of the first energy-saving strategy and the energy loss of the second energy-saving strategy is not limited. The first network device changes the energy-saving strategy currently running on the terminal through the second information, changing the currently running energy-saving strategy from the second energy-saving strategy to the first energy-saving strategy.

[0230] Optionally, in some embodiments, the energy consumption of the first energy-saving strategy can be lower than that of the second energy-saving strategy, thereby further saving energy and improving the terminal's battery life. For example, in this embodiment, the first network device can configure a first energy-saving strategy with lower energy consumption for the terminal according to the terminal's service distribution, thereby further reducing the terminal's energy consumption and improving the terminal's battery life.

[0231] Optionally, in some other embodiments, in order to ensure communication performance or even further improve communication performance, the energy consumption of the first energy-saving strategy can be configured to be higher than that of the second energy-saving strategy. This embodiment does not limit this.

[0232] Optionally, in some embodiments, the second information includes at least one of the following:

[0233] Terminal identifier;

[0234] First energy-saving mode;

[0235] Energy-saving configuration information for the first energy-saving mode.

[0236] For example, in this embodiment, the terminal is in a power-saving state, which may include: RRC idle state, RRC inactive state, or RRC low-power state. The terminal in the power-saving state switches states by listening to a wake-up signal sent by the first network device. This state switch may be from the currently running power-saving state to a normal interactive state. Optionally, this state switch may also be from the currently running second power-saving strategy to the first power-saving strategy. The first network device can instruct the terminal to change the power-saving strategy by carrying second information in the wake-up signal. The second information may include a terminal identifier that needs to adjust the power-saving strategy, so that the terminal responds to the terminal identifier and performs a power-saving strategy switch. The second information may also include at least one of the following: a first power-saving mode, and a first power-saving mode corresponding to the first power-saving strategy. For example, when the second information includes a first power-saving mode, the first power-saving strategy is used to change the terminal's currently running power-saving mode, and the terminal switches from the second power-saving mode corresponding to the second power-saving strategy to the first power-saving mode corresponding to the first power-saving strategy. When the second information includes energy-saving configuration information for the first energy-saving mode, the first energy-saving policy is used to change the energy-saving configuration of the first energy-saving mode in the terminal. At this time, the energy-saving mode corresponding to the second energy-saving policy currently running on the terminal is the same as the energy-saving mode corresponding to the first energy-saving policy. When the second information includes energy-saving configuration information for the first energy-saving mode and the first energy-saving mode, the first network device instructs the terminal to switch from the currently running second energy-saving mode to the first energy-saving mode, and performs the switch based on the energy-saving configuration of the first energy-saving mode.

[0237] Optionally, in some embodiments, the second information includes energy-saving configuration information, and the energy-saving mode corresponding to the first energy-saving strategy is the same as the energy-saving mode corresponding to the second energy-saving strategy.

[0238] For example, when the second information includes energy-saving configuration information for the first energy-saving mode, the energy-saving mode corresponding to the second energy-saving strategy currently running on the terminal is the same as the energy-saving mode corresponding to the first energy-saving strategy. The terminal switches between different configurations under the same energy-saving mode based on the second information.

[0239] Optionally, in some embodiments, the first energy-saving mode includes at least one of the following:

[0240] Energy-saving mode based on discontinuous listening paging of the intermittent reception cycle DRX-cycle;

[0241] Energy-saving mode for discontinuous listening paging based on extended intermittent reception eDRX;

[0242] Energy-saving mode based on terminal-initiated connection to MICO;

[0243] Energy-saving mode based on compact paging;

[0244] Energy-saving mode based on advance paging indication (PEI);

[0245] Power saving mode based on low-power wake-up signal LP-WUS;

[0246] Energy-saving mode based on synchronous paging reception using Tracking Reference Signal (TRS);

[0247] Energy-saving mode based on Wireless Resource Management (RRM) relaxation.

[0248] For example, (1) DRX is an energy-saving technology in the terminal. By configuring the DRX cycle for the terminal, the time is divided into "wake-up period" and "sleep period". During the wake-up period, the terminal listens to the PDCCH to check whether there are paging messages or other data transmissions; during the sleep period, the terminal enters a low-power state to achieve energy saving. The energy-saving mode of non-continuous listening paging based on DRX-cycle reduces the power consumption of the terminal by optimizing the paging listening behavior of the terminal;

[0249] (2) The power-saving mode of non-continuous listening paging based on eDRX is a technology that reduces power consumption by extending the terminal's sleep cycle. eDRX extends DRX, allowing the terminal to maintain a low-power state for a longer period of time and listen for network paging messages only within a specific paging time window;

[0250] (3) MICO mode is an energy-saving technology designed to reduce unnecessary signaling transmission and power consumption by limiting downlink connections and allowing terminals to initiate connections only when necessary. MICO mode is particularly suitable for IoT devices and other application scenarios that require long standby times and infrequent data transmission.

[0251] (4) Compact paging is an optimized paging mechanism designed to reduce power consumption by minimizing the paging listening overhead of the terminal. It achieves energy savings by compacting the structure and transmission method of paging messages, reducing unnecessary wake-up and listening time.

[0252] (5) The PEI power-saving mode aims to reduce the power consumption of the terminal in idle or inactive states. It informs the UE whether it needs to listen for subsequent paging messages via an early PEI indication before the paging opportunity. By sending an early indication before the paging opportunity, the PEI power-saving mode reduces the terminal's listening overhead and the probability of false paging, thereby reducing the device's power consumption.

[0253] (6) The LP-WUS power-saving mode reduces the power consumption of the terminal in the idle state by introducing a low-power wake-up signal and a low-power receiver;

[0254] (7) TRS is a sparse reference signal, mainly used for time and frequency tracking. In the idle or inactive state, the terminal needs to periodically receive synchronization signal blocks to obtain time and frequency tracking information. However, frequent wake-up to receive SSB increases power consumption. By using TRS, the terminal receives paging messages at the TRS time, reducing the number of frequent wake-ups due to receiving SSB, thereby reducing the power consumption of the device;

[0255] (8) The RRM-relax energy-saving mode reduces energy consumption of the terminal in RRM measurement by extending the measurement cycle, reducing paging monitoring and combining the eDRX mechanism.

[0256] Optionally, in some embodiments, the second information includes bitmap information used to indicate multiple first power-saving modes that are simultaneously activated in the terminal.

[0257] For example, in this embodiment, the power-saving mode activated in the terminal can be at least two first power-saving modes that are activated simultaneously. An indicator bitmap can be configured for each power-saving mode based on the multiple power-saving modes applicable to the terminal. The number of bits in the bitmap indicates to the terminal whether multiple first power-saving modes are activated simultaneously. For example, if the terminal uses four power-saving modes, including power-saving mode A, power-saving mode B, and power-saving mode C, the first bit in the bitmap indicates whether power-saving mode A is activated, the second bit indicates whether power-saving mode B is activated, and the third bit indicates whether power-saving mode C is activated. A bit value of 1 indicates activation of the corresponding power-saving mode, and a bit value of 0 indicates deactivation of the corresponding power-saving mode. When the bitmap is "011", the terminal activates both power-saving mode B and power-saving mode C simultaneously according to this bitmap.

[0258] Optionally, in some embodiments, the second information is encapsulated within the fifth information, which includes at least one of the following:

[0259] Paging messages;

[0260] RRC setting message;

[0261] RRC reconfiguration message;

[0262] RRC release message;

[0263] RRC signaling.

[0264] For example, in this embodiment, the second information is encapsulated in the fifth information, and the timing of the transmission of the second information is related to the terminal's RRC random access procedure.

[0265] For example, the first network device can send the second information to the terminal before the terminal initiates the RRC random access procedure. In this case, the fifth information is a paging message, and the first network device indicates the second information to the terminal based on the paging message.

[0266] The first network device can also send second information to the terminal during the RRC random access process. For example, if the terminal is in an RRC idle state and sends an RRC connection request to the first network device, the fifth information is an RRC setup message or an RRC reconfiguration message. The first network device indicates the second information to the terminal based on the RRC setup message or RRC reconfiguration message. If the terminal is in an RRC inactive state and sends an RRC recovery request to the first network device, the first network device indicates the second information to the terminal based on the RRC release message.

[0267] The first network device can also send a second message to the terminal after the terminal completes the RRC random access procedure. At this time, the fifth message is other RRC signaling, and the first network device indicates the second message to the terminal based on the RRC signaling.

[0268] In step S2104, the terminal 101 changes the energy-saving strategy from the second energy-saving strategy to the first energy-saving strategy based on the second information.

[0269] For example, the terminal switches its energy-saving strategy based on the second information sent by the first network device, switching from the currently running second energy-saving strategy to the first energy-saving strategy indicated by the first network device.

[0270] Optionally, in some embodiments, after step S2104 described above, the method further includes:

[0271] Terminal 101 sends third information to the first network device 102.

[0272] In some embodiments, the third information is used to indicate that the energy-saving policy change in the terminal was successful.

[0273] For example, after the energy-saving strategy in the terminal is successfully changed, third information is fed back to the first network device, so that the first network device can promptly confirm the current energy-saving status of the terminal, determine whether the terminal has entered the expected energy-saving strategy, and avoid communication problems caused by inconsistent status.

[0274] In some embodiments, the first network device 102 receives third information.

[0275] Optionally, in some embodiments, after the above step "the first network device receives the third information", the method further includes:

[0276] A first network device sends third information to a second network device, wherein the second network device includes at least one of the following:

[0277] Access network equipment within the Radio Access Network (RAN);

[0278] Core network equipment.

[0279] For example, after receiving a message from the terminal indicating a successful change in the energy-saving policy, the first network device needs to synchronize the terminal's current energy-saving policy with other network devices. Therefore, the first network device sends this third information to other access network devices within the corresponding notification area of ​​the RAN (Radio Access Network), or sends it to the core network device, thereby synchronizing the terminal's status with the second network device and avoiding communication problems caused by inconsistent status.

[0280] Optionally, in some embodiments, after the above step "the first network device receives the third information", the method further includes:

[0281] The first network device executes the terminal's RRC link establishment process or the terminal's RRC link reply process based on the third information.

[0282] For example, in this embodiment, the terminal is in an RRC low-power state or an RRC inactive state. The first network device sends a second message to the terminal via a paging message. The terminal adjusts its energy-saving strategy based on the second message and sends a third message to the first network device to report that the energy-saving strategy change in the terminal has been successful. This third message can be encapsulated in an RRC random access request message. In response to the third message, the first network device executes the terminal's RRC random access procedure.

[0283] For example, the terminal is in an RRC inactive state before receiving the second information. After the terminal changes the energy-saving policy based on the second information, it sends an RRC recovery request to the first network device. The RRC recovery request carries the third information. For example, the RRC recovery request can also be an RRC recovery request + MAC CE (Media Access Control Element), where the third information carried in the MAC CE is used to indicate that the energy-saving policy change in the terminal was successful.

[0284] Before receiving the second information, the terminal is in an RRC idle state. After changing the energy-saving strategy based on the second information, the terminal sends an RRC connection request to the first network device, which carries the third information.

[0285] Optionally, in some embodiments, the third information includes at least one of the following:

[0286] RRC connection request;

[0287] RRC recovery request;

[0288] Mobile initiates early data transmission MO-EDT information;

[0289] Mobile initiates short data transmission of MO-SDT information.

[0290] For example, for a terminal in RRC inactive state, after the terminal changes its energy-saving policy based on the second information, it can send a successful energy-saving policy change indication to the first network device via an RRC recovery request; for a terminal in RRC idle state, after the terminal changes its energy-saving policy based on the second information, it can send a successful energy-saving policy change indication to the first network device via an RRC connection request. Optionally, the terminal can also send a successful energy-saving change indication to the first network device via MO-EDT (Mobile Originated Early Data Transmission) information or MO-SDT (Mobile Originated Small Data Transmission) information.

[0291] Optionally, in some embodiments, the RRC connection request includes the Logical Channel Identifier (LCID) of the Common Control Channel (CCCH).

[0292] For example, in this embodiment, the LCID (Logical Channel Identification) value of the CCCH (Common Control Channel) in the RRC connection request can be used to indicate whether the power-saving policy in the terminal has been changed successfully. For instance, when the LCID value is 1, it indicates that the power-saving policy in the terminal has been changed successfully; when the LCID value is 0, it indicates that the power-saving policy in the terminal has failed to be changed.

[0340] Figure 4A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4A, the embodiments of the present disclosure relate to a communication method, which includes:

[0341] In step S4101, the CN sends a paging message to the serving base station, which includes the new power mode and / or power mode configuration information.

[0342] In some embodiments, the power-saving mode of the terminal may include at least one of the following:

[0343] (1) The energy-saving mode of non-continuous listening paging based on DRX cycle can be further divided into different DRX cycle configurations under this mode;

[0344] (2) Energy-saving mode for discontinuous listening paging based on eDRX;

[0345] (3) Energy-saving mode based on MICO;

[0346] (4) Energy-saving mode based on compact paging;

[0347] (5) Energy-saving mode based on PEI;

[0348] (6) Energy-saving mode based on LP-WUS;

[0349] (7) Energy-saving mode based on TRS synchronous reception paging;

[0350] (8) Energy-saving mode based on RRM relax. Energy saving is achieved by reducing the power consumption of the UE in RRM measurement, for example, by extending the measurement cycle, reducing paging snooping, and combining eDRX mechanism.

[0351] Among them, the above-mentioned energy-saving modes (1)-(7) are all energy-saving modes related to paging reception, and the above-mentioned energy-saving mode (8) is an energy-saving mode related to measurement relaxation.

[0352] In some embodiments, the network side obtains the service distribution information of the terminal and changes the terminal's power-saving mode. For example, the power-saving mode can be changed through paging. For example, the paging message carries the paged UE-ID, as well as the power-saving mode and / or different configurations under different power-saving modes. For example, if the UE only has uplink services at this time, the UE is told to switch from DRX to MICO state; the paging message carries the UE ID and the state to be switched, such as eDRX, MICO.

[0353] In some embodiments, service distribution information may be, for example, the arrival time distribution of service data packets, the time interval between service data packets, the duration of each service arrival, the size of the data packet, etc.

[0354] In some embodiments, the activated power-saving modes can be at least two that are activated simultaneously, such as RRM Relax and PEI that can be activated simultaneously. Therefore, the network side can indicate the bitmap to indicate the different power-saving modes that are activated simultaneously.

[0355] In some embodiments, the network side may also indicate switching between different configurations within the same power-saving mode. For example, switching between different DRX cycle configurations.

[0356] In some embodiments, for a power-saving mode change triggered by a paging message or a configuration information change within a power-saving mode, the UE updates the message and executes an RRC link establishment or RRC link recovery procedure, indicating a successful change based on Msg3 or Msg5. Alternatively, the UE can send a power-saving mode change success indication based on MT-EDT or MT-SDT. The indication is carried in Msg3, either within the Msg3 message itself or determined based on the LCID value of the CCCH in Msg3.

[0357] In step S4102, the serving base station sends a paging message to the UE, which includes the new power mode and / or power mode configuration information.

[0358] For example, for a UE in RRC idle mode, the CN (Core Network) device determines to change the terminal's power saving mode and sends a paging message to the serving base station. This paging message carries the paging reason or power mode update indication, and the serving base station will send the paging message to the UE.

[0359] In step S4103, the UE sends an RRC setting request message to the serving base station, which carries an indication of successful power saving mode update.

[0360] In step S4104, the serving base station sends an RRC setting message to the UE, which carries the target power mode and / or configuration information changed under the power mode.

[0361] In step S4105, the UE sends an RRC setting completion message to the serving base station, which carries an indication of successful power saving mode update.

[0362] In step S4106, after the UE enters the RRC connection state, it sends power-saving mode update indication information to the serving base station through other RRC signaling.

[0363] In step S4107, after receiving the success indication, the serving base station forwards the power saving mode update indication information to the CN via NGAP.

[0364] It should be noted that, due to the limited message size in paging messages, further information can be sent via MT-EDT / MT-SDT to indicate power-saving mode changes and / or switching between different configurations within the same power-saving mode. Because it's MT-EDT / MT-SDT, the paging message can indicate that the paging reason is a power-saving mode change.

[0365] In some embodiments, if an arrow in the interaction diagram representing the sending of information, signaling, etc., from one subject to another passes through other subjects, it can be interpreted as the message being forwarded from one subject to another via other subjects, or it can be interpreted as the message being sent from one subject to another without passing through other subjects.

[0366] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0367] Figure 4B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4B, the present disclosure relates to a communication method, which includes:

[0368] In step S4201, the primary base station sends a RAN paging message to the serving base station, which includes a new power mode and / or power mode configuration information.

[0369] For example, for a UE in RRC low-power state, the primary base station determines to change the terminal's power-saving mode and sends a paging message to other base stations within the RNA. This paging message carries the new power mode and / or power mode configuration information.

[0370] In step S4202, after receiving the RAN paging message, the serving base station sends a paging message to the UE, which includes the new power mode and / or power mode configuration information.

[0371] In step S4203, the UE sends an RRC connection restoration request message to the serving base station, which carries an indication of successful power saving mode update.

[0372] For example, the Msg3 message can also be an RRC connection recovery request message + MACCE, where MACCE indicates either power-saving mode or a successful configuration update indication.

[0373] In step S4204, the serving base station sends an RRC release message to the UE, which includes the new power mode and / or power mode configuration information.

[0374] In step S4205, after receiving the power saving mode update success indication information, the serving base station forwards the information to the main base station.

[0375] Optionally, in some embodiments, after the UE enters the RRC connection state, it can also send power-saving mode update success indication information to the network side via RRC dedicated signaling, such as UE auxiliary information.

[0376] In some embodiments, if an arrow in the interaction diagram representing the sending of information, signaling, etc., from one subject to another passes through other subjects, it can be interpreted as the message being forwarded from one subject to another via other subjects, or it can be interpreted as the message being sent from one subject to another without passing through other subjects.

[0377] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0378] Figure 4C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4C, the embodiments of the present disclosure relate to a communication method, which includes:

[0379] In step S4301, CN sends a RAN paging message to the serving base station, which carries a paging reason or power mode update indication.

[0380] For example, for a UE in RRC idle state, the CN device determines to change the terminal's power saving mode and sends a paging message to the base station. The paging message carries the paging reason or power mode update indication.

[0381] In step S4302, the serving base station sends a paging message to the UE, which carries a paging reason or power mode update indication.

[0382] In step S4303, the UE sends an RRC setting request message to the serving base station.

[0383] In step S4304, the serving base station sends an RRC setting message to the UE, which carries the target power mode and / or configuration information of the changes in the power mode.

[0384] Step S4305: The terminal sends an RRC setup complete message to the current serving base station.

[0385] For example, after the UE enters the RRC linked state, it can also send the target power mode and / or configuration information for changes in the power mode via other dedicated RRC signaling. For example, RRC reconfiguration information.

[0386] In some embodiments, if an arrow in the interaction diagram representing the sending of information, signaling, etc., from one subject to another passes through other subjects, it can be interpreted as the message being forwarded from one subject to another via other subjects, or it can be interpreted as the message being sent from one subject to another without passing through other subjects.

[0387] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0388] Figure 4D is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4D, the present disclosure relates to a communication method, which includes:

[0389] In step S4401, the primary base station sends a RAN paging message to the serving base station, which carries a paging reason or power mode update indication.

[0390] For example, for a UE in an RRC inactive state, the primary gNB determines to change the terminal's power-saving mode and sends a paging message to other base stations within the RNA. This paging message carries a paging reason or a power mode update indication.

[0391] In step S4402, the serving base station sends a paging message to the UE, which carries a paging reason or power mode update indication.

[0392] In step S4403, the UE sends an RRC connection restoration request message to the serving base station.

[0393] In step S4404, the serving base station sends an RRC release message to the UE, which carries the target power mode and / or configuration information changed under the power mode.

[0394] In some embodiments, if an arrow in the interaction diagram representing the sending of information, signaling, etc., from one subject to another passes through other subjects, it can be interpreted as the message being forwarded from one subject to another via other subjects, or it can be interpreted as the message being sent from one subject to another without passing through other subjects.

[0395] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0396] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0397] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device.

The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0398] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
