[0036] The terminal energy saving method provided by the embodiment of the present application is described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0037] As shown in FIG2 , an embodiment of the present application provides a terminal energy saving method 200. The method can be executed by a terminal device. In other words, the method can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0038] S202: The terminal sends first information to the core network device.

[0039] It should be noted that the terminal in the embodiment of the present application may also be referred to as user equipment (UE), and the terminal and UE may be used interchangeably.

[0040] In related terminal energy-saving solutions, the terminal's standby time can be extended by reducing power consumption in the idle state. However, in some scenarios, energy conservation can also be achieved by scheduling more resources and providing services to the terminal. For example, a terminal consumes more power in the non-idle state, and energy conservation alone in the idle state cannot meet the terminal's energy conservation needs. However, energy conservation in the non-idle state cannot be achieved by reducing terminal power consumption; instead, more resources must be scheduled to provide services to the terminal. However, scheduling more resources and providing services to the terminal will affect the overall efficiency of network resources to a certain extent. If the access network equipment or the terminal determines whether to perform terminal energy conservation, it may lead to uncontrolled network resource management and significantly reduce the overall efficiency of network resources. To this end, the embodiment of the present application implements energy-saving parameters for terminal energy conservation through this step, which are negotiated between the core network equipment and the UE and determined by the core network equipment. Although scheduling more resources and providing services to the terminal may affect the overall efficiency of network resources to a certain extent, unified management by the core network equipment can effectively coordinate network resources among multiple devices under the core network equipment's jurisdiction, achieving both terminal energy conservation and maintaining overall network performance without excessive impact. In this step, to negotiate energy-saving parameters for the terminal with the core network device, the terminal sends first information to the core network device. The first information indicates that the terminal has energy-saving requirements. Thus, the core network device can determine second information and / or third information for the terminal based on the first information. The second information indicates to the access network device the energy-saving parameters for the terminal determined or configured by the core network device, and the third information indicates to the terminal the energy-saving parameters for the terminal determined or configured by the core network device. The second information and the third information can be the same, or the third information can include at least a portion of the second information.

[0041] In one implementation, the terminal sends the first information to the core network device in a non-idle state, where the energy-saving requirement includes at least one of the following: an energy-saving requirement of a terminal in a connected state, an energy-saving requirement of a terminal in an inactive radio resource control (RRC) state, and an energy-saving requirement of a terminal during data transmission. Compared to a terminal in a non-connected state, the battery power consumption of the terminal in the connected state is greater, thereby reducing the battery power consumption of the terminal in the connected state.

[0042] S204: Receive third information sent by the core network device.

[0043] The third information is used to indicate the energy-saving parameter for the terminal energy saving determined by the core network device. The terminal determines, based on the third information, that its energy-saving request has been responded to, and determines that the core network device accepts the terminal energy-saving request or determines that the core network device will provide the terminal energy-saving service.

[0044] Therefore, in the embodiment of the present application, the terminal and the core network network device can negotiate the energy-saving parameters for the terminal energy saving, and the core network network device can provide the energy-saving parameters for the terminal energy saving to the base station so that the base station adopts energy-saving transmission for the UE based on the energy-saving parameters for the terminal energy saving, and the core network network device can provide the energy-saving parameters for the terminal energy saving to the UE to determine that the core network network device will provide terminal energy-saving services.

[0045] In one implementation, the first information includes: at least one of: energy-saving capability, energy-saving mode indication, energy-saving session request, and energy-saving parameters of the requested QoS flow granularity. In one embodiment, the energy-saving capability is used to indicate whether the terminal (UE) supports energy saving. The UE can indicate to the network whether the UE supports energy saving. When the UE indicates to the network that the UE supports energy saving, it indicates that the UE has energy saving requirements. In one embodiment, whether the UE supports energy saving includes at least one of the following: whether the UE supports energy efficiency (whether energy efficiency is supported or not) and whether the UE supports battery saving (whether battery saving is supported or not).

[0046] In another embodiment, the energy saving capability may be used to indicate the battery life of the UE.

[0047] In one embodiment, the energy-saving mode indication is used to indicate whether a terminal (UE) supports the energy-saving mode or to indicate that the terminal requests to use the energy-saving mode. The energy-saving mode can be understood as a mode in which more resources can be scheduled for the terminal. When the UE indicates to the network that it supports the energy-saving mode or indicates that the terminal requests to use the energy-saving mode, it indicates that the UE has an energy-saving requirement.

[0048] In one embodiment, an energy-saving session request is used to indicate whether at least one session (e.g., a Protocol Data Unit (PDU) session) is requested to be established as an energy-saving session. It is understood that the energy-saving session request is used to indicate whether the requested session (e.g., a PDU session) needs to be allowed to be established as an energy-saving session. It should be noted that an energy-saving session can be understood as scheduling more resources for the session. In this mode, more resources can be scheduled for the terminal. When the UE indicates to the network that the requested session needs to be allowed to be established as an energy-saving session, it indicates that the UE has energy-saving requirements.

[0049] In one embodiment, energy-saving parameters at the requested QoS flow granularity are used to indicate to the UE that the requested QoS flow is to be modified into an energy-saving QoS flow. Each energy-saving parameter at the requested QoS flow granularity may be associated with one QoS flow. It is understood that energy-saving parameters at the requested QoS flow granularity refer to energy-saving parameters requested per QoS flow. When the UE indicates to the network that it wants to establish or modify the requested QoS flow into an energy-saving QoS flow, it indicates that the UE has an energy-saving requirement.

[0050] In one implementation, the energy-saving capability may be included in a first information element, and the first information element may include an existing information element or a newly added information element.

[0051] In one embodiment, the existing information element may include, for example, a 5G Mobility Management capability Information Element (5GMM capability IE), a 5G System update type Information Element (5G System update type Information Element, 5GS update type IE), or a 5G Session Management capability Information Element (5GSM capability IE).

[0052] In one embodiment, the energy saving capability may be included in the encoding of the existing information element, for example: support energy efficiency mode (energy efficiency supported), not support energy efficiency mode (energy efficiency not supported); support energy saving mode (energy saving supported), not support energy saving mode (energy saving not supported), etc.

[0053] In one implementation, a new information element is used to carry terminal energy-saving related parameters, for example, a new energy efficiency indication information element (energy efficiency indication IE) is used to indicate whether energy saving is supported.

[0054] In one implementation, the energy-saving mode indication may be included in a second information element, and the second information element may be included in an existing information element or a newly added information element.

[0055] In one embodiment, the existing information element may include, for example, a 5GMM capability IE, a 5GS update type IE, or a 5GSM capability IE. The encoding of the energy-saving mode indication when included in the existing information element may be, for example, energy efficiency mode supported, energy efficiency mode not supported, energy saving mode supported, energy saving mode not supported, etc.

[0056] In one embodiment, a new information element is used to carry terminal energy-saving related parameters, for example, a new energy efficiency mode indication information element (energy efficiency mode indication IE) is used to indicate whether the energy-saving mode is supported.

[0057] In one implementation, the third information includes at least one of an energy-saving service indication, an energy-saving mode notification, an energy-saving session indication, an energy-saving parameter of a session granularity, and an energy-saving parameter of a QoS flow granularity.

[0058] In one embodiment, the energy-saving service indication is used to indicate whether the core network network device supports and accepts the provision of energy-saving services for the terminal, or whether the core network network device determines that it will provide energy-saving services for the terminal. In one embodiment, the access network network device can be configured with transmission parameters corresponding to energy-saving services and transmission parameters corresponding to non-energy-saving services. When receiving an indication that the core network network device supports and accepts the provision of energy-saving services for the terminal, data is transmitted using the transmission parameters corresponding to the energy-saving services. At this time, the third information received by the terminal also indicates that the core network network device supports and accepts the provision of energy-saving services for the terminal. On the contrary, when the access network network device receives an indication that it does not support and accept the provision of energy-saving services for the terminal, data is transmitted using the transmission parameters corresponding to non-energy-saving services. At this time, the third information received by the terminal also indicates that the core network network device does not support and accept the provision of energy-saving services for the terminal.

[0059] In one embodiment, the energy-saving mode notification is used to notify the core network network device whether it supports and accepts configuring the terminal to use the energy-saving mode. In one embodiment, the access network network device can be configured with transmission parameters corresponding to the energy-saving mode and transmission parameters corresponding to the non-energy-saving mode. When receiving an indication that the core network network device supports and accepts configuring the terminal to use the energy-saving mode, data is transmitted using the transmission parameters corresponding to the energy-saving mode. At this time, the third information received by the terminal also indicates that the core network network device supports and accepts configuring the terminal to use the energy-saving mode. On the contrary, when the access network network device receives an indication that the energy-saving mode is not used, data is transmitted using the transmission parameters corresponding to the non-energy-saving mode. At this time, the third information received by the terminal also indicates that the core network network device does not support and accept configuring the terminal to use the energy-saving mode.

[0060] In one embodiment, the energy-saving session indication is used to indicate whether a session, such as a PDU session, is allowed to be established as an energy-saving session. It can be understood that the energy-saving session indication is used to indicate that the corresponding session will be allowed to be established as an energy-saving session. In one embodiment, the access network network device can be configured with transmission parameters corresponding to the energy-saving session and transmission parameters corresponding to the non-energy-saving session. When receiving an indication that the core network network device is to configure the terminal as an energy-saving session, data is transmitted using the transmission parameters corresponding to the energy-saving session. At this time, the third information received by the terminal also indicates that the core network network device is allowed to establish the session as an energy-saving session. On the contrary, when the access network network device receives an indication that the session is not allowed to be established as an energy-saving session, data is transmitted using the transmission parameters corresponding to the non-energy-saving session. At this time, the third information received by the terminal also indicates that the core network network device is not allowed to establish the corresponding session as an energy-saving session.

[0061] In one embodiment, session-granular energy-saving parameters are used to indicate that a session, such as a PDU session, is established or will be permitted to be established as an energy-saving session. Each session-granular energy-saving parameter can be associated with a session. In one embodiment, upon receiving the session-granular energy-saving parameters, the access network device transmits data using the session-granular energy-saving parameters. In this case, the third information received by the terminal also indicates the session-granular energy-saving parameters.

[0062] In one embodiment, energy-saving parameters at the QoS flow granularity are used to instruct a core network device to modify a QoS flow into an energy-saving QoS flow. Each energy-saving parameter at the QoS flow granularity can be associated with a QoS flow. It is understood that energy-saving parameters at the QoS flow granularity refer to energy-saving parameters corresponding to each QoS flow. In one embodiment, upon receiving energy-saving parameters at the QoS flow granularity, the access network device transmits data using the energy-saving parameters at the QoS flow granularity. At this time, the third information received by the terminal also indicates the energy-saving parameters at the QoS flow granularity.

[0063] In one implementation, the energy-saving service indication is included in a third information element, and the third information element includes at least one of the following:

[0064] 5GS network feature support IE, 5GS update type IE, and energy efficiency indication IE. The energy efficiency indication IE is used to indicate whether energy saving is supported.

[0065] In one implementation, the encoding of the energy-saving service indication includes at least one of the following:

[0066] energy efficiency supported, energy efficiency not supported, energy saving supported, energy saving not supported.

[0067] In one implementation, the energy-saving mode notification is included in a fourth information element, and the fourth information element includes at least one of the following:

[0068] 5GMM capability IE, 5GS update type IE and 5GSM capability IE, energy saving mode indication information element (EE indication IE), the energy saving mode indication information element is used to indicate whether the energy saving mode is supported.

[0069] In one implementation, the encoding of the energy-saving mode notification includes at least one of the following: energy efficiency supported, energy efficiency not supported, energy saving supported, and energy saving not supported.

[0070] In one implementation, when the first information includes energy-saving capabilities, the third information includes an energy-saving service indication. For example, if the terminal has energy-saving capabilities, in this embodiment, the terminal sends first information carrying its own energy-saving capabilities to the core network device, thereby indicating that the terminal has energy-saving requirements and requests negotiation with the core network device regarding energy-saving parameters for terminal energy saving. The core network device determines whether to configure or provide an energy-saving service indication for the terminal. The third information carries the energy-saving service indication determined by the core network device, notifying the UE whether the core network device configures or provides energy-saving services for the terminal, thereby providing UE-granular energy-saving services.

[0071] In one implementation, when the first information includes an energy-saving mode indication, the third information includes an energy-saving mode notification. For example, if the terminal supports the energy-saving mode or requests to use the energy-saving mode, in this embodiment, the terminal sends first information to the core network device to indicate that it supports the energy-saving mode or requests to use the energy-saving mode. In this way, the terminal indicates that it has energy-saving requirements and requests to negotiate with the core network device on energy-saving parameters for terminal energy saving. The core network device determines whether to support and accept configuring the terminal to use the energy-saving mode, and notifies the UE through the energy-saving mode notification, thereby providing UE-granular energy-saving services.

[0072] In one implementation, when the first information includes an energy-saving session request, the third information includes an energy-saving session indication or a session-granular energy-saving parameter. For example, in this embodiment, the terminal sends an energy-saving session request to the core network device, thereby indicating that the terminal has energy-saving requirements and requests to establish a session as an energy-saving session. The core network device determines whether the session is allowed to be established as an energy-saving session and notifies the UE through the energy-saving session indication, thereby providing session-granular energy-saving services.

[0073] In one implementation, when the first information includes energy-saving parameters at the requested QoS flow granularity, the third information includes the energy-saving parameters at the QoS flow granularity. For example, in this embodiment, the terminal sends the energy-saving parameters at the QoS flow granularity to the core network device, thereby indicating that the UE wants to modify the requested QoS flow to an energy-saving QoS flow. The core network device determines whether the requested QoS flow is modified to an energy-saving QoS flow and notifies the UE of the energy-saving parameters at the QoS flow granularity, thereby providing energy-saving services at the QoS flow granularity.

[0074] Therefore, the embodiments of the present application can provide energy-saving services of different granularities.

[0075] In one implementation, the first information is included in a communication message between the terminal and the core network device. In one implementation, the third information may be included in a response message to the communication message.

[0076] In one implementation, the communication message may be an existing message. For example, the communication message may include at least one of the following:

[0077] Mobility management message; for example, at least one of a registration request, a service request, an uplink non-access stratum transport message (UL NAS transport), and a control plane service request message. In this case, the device that determines the second information or the third information in the core network device may include a device with access and management functions (e.g., AMF);

[0078] Session management message, the session management message is used to establish a data transmission channel between the terminal and the session management function; for example, the session management message can be at least one of a PDU session establishment request message and a PDU session modification message. In this case, the device that determines the second information or the third information in the core network device may include a device with a session management function (such as SMF).

[0079] In another implementation, the communication message may be a newly added message. For example, the communication message may include at least one of the following:

[0080] Control plane message, the control plane message is used to transmit management-related information between the terminal and the control node, the management-related information includes: the management-related information includes at least one of the following: mobility management-related information, connection management-related information, session management-related information, task management-related information and policy control-related information. For example, the functions of AMF and SMF can be coupled, and the control messages of AMF and SMF can be indistinguishable.

[0081] Energy-saving control message, the energy-saving control message is used to transmit energy-saving control related information, such as energy-saving ratio, between the terminal and the energy-saving control node. The control node is a newly added network element. The control node is responsible for energy-saving control including: energy-saving parameter (second information and / or third information) generation, energy-saving network element selection, energy-saving session management, etc.

[0082] In one implementation, when the first information includes at least one of an energy-saving capability and an energy-saving mode indication, the terminal sends a mobility management message to the core network device, where the mobility management message includes the first information.

[0083] In one implementation, when the first information includes at least one of an energy-saving session request and an energy-saving parameter for a requested QoS flow granularity, the terminal sends a session management message to the core network device, the session management message including the first information, and the session management message is used to establish a session between the terminal and a session management function. The session can serve as a data transmission channel between the terminal and the session management function.

In one embodiment, the access network network device can be configured with transmission parameters corresponding to energy-saving services and transmission parameters corresponding to non-energy-saving services. When receiving the second information indicating that the core network network device supports and accepts the provision of energy-saving services for the terminal, data is transmitted using the transmission parameters corresponding to the energy-saving services. At this time, the third information received by the terminal also indicates that the core network network device supports and accepts the provision of energy-saving services for the terminal. On the contrary, when the access network network device receives the second information indicating that it does not support and accept the provision of energy-saving services for the terminal, data is transmitted using the transmission parameters corresponding to non-energy-saving services.

It can be understood that the energy-saving session indication is used to indicate that the corresponding session will be allowed to be established as an energy-saving session. In one embodiment, the access network network device can be configured with transmission parameters corresponding to the energy-saving session and transmission parameters corresponding to the non-energy-saving session. When receiving the second information indicating that the core network network device configures the terminal as an energy-saving session, data is transmitted using the transmission parameters corresponding to the energy-saving session. At this time, the third information received by the terminal also indicates that the core network network device will allow the session to be established as an energy-saving session. On the contrary, when the access network network device receives the second information indicating that the session is not allowed to be established as an energy-saving session, data is transmitted using the transmission parameters corresponding to the non-energy-saving session. At this time, the third information received by the terminal also indicates that the corresponding session of the core network device is not allowed to be established as an energy-saving session.

[0142] In one embodiment, session-granular energy-saving parameters are used to indicate that a session, such as a PDU session, is established or will be permitted to be established as an energy-saving session. Each session-granular energy-saving parameter can be associated with a session. In one embodiment, when the access network device receives the second information including the session-granular energy-saving parameters, it transmits data using the session-granular energy-saving parameters. At this time, the third information received by the terminal also indicates the session-granular energy-saving parameters.

[0143] In one embodiment, the energy-saving parameters at the QoS flow granularity are used to instruct a core network device to determine whether to modify a QoS flow to an energy-saving QoS flow. Each energy-saving parameter at the QoS flow granularity can be associated with a QoS flow. It is understood that the energy-saving parameters at the QoS flow granularity refer to energy-saving parameters corresponding to each QoS flow. In one embodiment, when the access network device receives the second information including the energy-saving parameters at the QoS flow granularity, it transmits data using the energy-saving parameters at the QoS flow granularity. At this time, the third information received by the terminal also indicates the energy-saving parameters at the QoS flow granularity.

[0151] In one implementation, when the first information includes energy-saving capabilities, the second information includes an energy-saving service indication, and the third information includes an energy-saving service indication. For example, if the terminal has energy-saving capabilities, in this embodiment, the terminal sends first information carrying its own energy-saving capabilities to the core network device, thereby indicating that the terminal has energy-saving requirements and requests negotiation with the core network device on energy-saving parameters for terminal energy saving. The core network device determines whether to configure or provide an energy-saving service indication for the terminal. The second information carries the energy-saving service indication determined by the core network device, notifying the access network device whether to configure or provide energy-saving services for the terminal. The third information carries the energy-saving service indication determined by the core network device, notifying the UE whether the core network device configures or provides energy-saving services for the terminal, thereby providing UE-granular energy-saving services.

[0152] In one implementation, when the first information includes an energy-saving mode indication, the second information includes an energy-saving mode notification, and the third information includes an energy-saving mode notification. For example, if the terminal supports the energy-saving mode or requests to use the energy-saving mode, in this embodiment, the terminal sends first information to the core network device to indicate that it supports the energy-saving mode or requests to use the energy-saving mode. In this way, the terminal indicates that it has energy-saving requirements and requests to negotiate with the core network device on energy-saving parameters for terminal energy saving. The core network device determines whether to support and accept configuring the terminal to use the energy-saving mode, and notifies the access network device and / or UE through the energy-saving mode notification, thereby providing UE-granular energy-saving services.

[0153] In one implementation, when the first information includes an energy-saving session request, the second information includes an energy-saving session indication or a session-granular energy-saving parameter, and the third information includes an energy-saving session indication or a session-granular energy-saving parameter. For example, in this embodiment, the terminal sends an energy-saving session request to the core network device, thereby indicating that the terminal has energy-saving requirements and requests that a session be established as an energy-saving session; the core network device determines whether the session is allowed to be established as an energy-saving session, and notifies the access network device and / or UE through the energy-saving session indication notification, thereby providing session-granular energy-saving services.

[0154] In one implementation, when the first information includes energy-saving parameters at the requested QoS flow granularity, the second information includes energy-saving parameters at the QoS flow granularity, and the third information includes energy-saving parameters at the QoS flow granularity. For example, in this embodiment, the terminal sends energy-saving parameters at the QoS flow granularity to the core network device, thereby indicating that the UE wants to modify the requested QoS flow to an energy-saving QoS flow. The core network device determines whether the requested QoS flow is modified to an energy-saving QoS flow, and notifies the access network device and / or the UE of the energy-saving parameters at the QoS flow granularity, thereby providing energy-saving services at the QoS flow granularity.

[0155] Therefore, the embodiments of the present application can provide energy-saving services of different granularities.

[0156] In one implementation, when the second information and the third information are determined, the third information includes at least a portion of the second information.

[0157] In one implementation, the first information is included in a communication message between the terminal and the core network device, and the third information is included in a response message to the communication message.

In this case, the device that determines the second information or the third information in the core network device may include a device with access and management functions (such as AMF);

[0160] Session management message, the session management message is used to establish a data transmission channel between the terminal and the session management function; for example, the session management message can be at least one of a PDU session establishment request message and a PDU session modification message. In this case, the device that determines the second information or the third information in the core network device may include a device with a session management function (such as SMF).

[0163] Energy-saving control message, the energy-saving control message is used to transmit energy-saving control related information, such as energy-saving ratio, between the terminal and the energy-saving control node. The control node is a newly added network element. The control node is responsible for energy-saving control including: energy-saving parameter (second information and / or third information) generation, energy-saving network element selection, energy-saving session management, etc.

[0164] In one implementation, when the first information includes at least one of an energy-saving capability and an energy-saving mode indication, the terminal sends a mobility management message to the core network device, where the mobility management message includes the first information.

[0167] In one implementation, when the first information includes at least one of an energy-saving capability and an energy-saving mode indication, the terminal sends an energy-saving control message to the core network device, and the energy-saving control message is used to transmit energy-saving control related information between the terminal and the control node.

[0168] In one implementation, the core network device is configured to perform access and mobility management functions or session management functions. The core network device may include an SMF or an AMF. When the core network device is an AMF, the communication message is a mobility management message, including at least one of a registration request message, an uplink non-access layer transmission message, a service request message, and a control plane service request message. When the core network device is an SMF, the communication message is a session management message, including at least one of a PDU session establishment request message and a PDU session modification message.
