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.

[0209] 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.

[0211] In some embodiments, to provide an immersive service experience, next-generation communication systems need to deliver long-duration, high-data-rate data transmission with low power consumption on devices. Considering end-to-end energy efficiency, the energy consumption of the entire communication system also needs to be optimized. To achieve energy efficiency, operators need to introduce the concept of energy as a service, offering users different levels of energy-saving services. For users, when subscribing to specific application services (such as AR, XR), they will have the opportunity to choose an energy-saving level according to their needs.

[0212] For example, this embodiment provides an application example of an energy-saving service:

[0213] (1) M purchased a new AR glasses and subscribed to an application service with an energy efficiency rating of A or B issued by operator A;

[0214] (2) Operator A operates the network and provides communication services to M;

[0215] (3) When the AR glasses’ battery is fully charged or the M is readily available for charging, the network will not perform any operations that support UE energy saving, which may result in higher energy consumption / power consumption of the AR glasses.

[0216] (4) When the battery capacity of the AR glasses drops below 20%, and M is unable to charge the AR glasses in time, he will switch the AR glasses to power saving mode.

[0217] If M selects UE energy saving level A, the service experience will not be affected by the device's battery status. The negotiation between the UE and the network will minimize the UE's energy consumption (communication part) to extend battery life. Some energy-saving functions (such as cell-DTX (Cell Discontinuous Transmission), UE-DRX (User Equipment Discontinuous Reception), LP-WUS (Low-Power Wake-Up Signal)) may be used to improve energy efficiency, thereby reducing the UE's energy consumption without reducing the service experience.

[0218] If M selects UE power saving level B, the network will modify the service experience with the UE's consent, such as modifying QoS (Quality of Service) to further extend battery life.

[0219] (5) Operator A monitors and generates UE-level energy efficiency and energy consumption.

[0220] Therefore, modifying the service experience to meet energy efficiency targets when the UE's battery power is low is a challenge. This embodiment proposes a method to modify the service experience to achieve energy consumption targets. For example, considering the UE's energy consumption during the establishment and modification of a PDU (Protocol Data Unit) session, the communication energy consumption of the UE can be reduced by establishing an energy-saving PDU session or modifying the currently executing PDU session.

[0221] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0222] Step S2101: The terminal sends energy information to the first network element.

[0223] In some embodiments, the first network element receives energy information.

[0224] In some embodiments, energy information is used for session establishment.

[0225] For example, in this embodiment, the interaction process between the terminal and the network device is an interaction process associated with an energy-saving service. This energy-saving service is used to reduce the energy consumption generated during the interaction between the terminal and the network device. This energy consumption includes the energy consumption of the terminal during communication interaction, for example, reducing battery power consumption during the interaction between the terminal and the network device. Optionally, the energy-saving service can also be used to optimize or reduce the energy consumption of various network nodes configured in the network device. For example, based on the energy-saving service, the communication interaction network element can be adjusted, replacing network element A with network element B, where network element A and network element B perform the same function during communication interaction, and the energy consumption of network element A is greater than or better than the energy consumption of network element B.

[0226] In some embodiments, a network device may be configured with multiple network elements, including various network elements with fixed functions. For example, an AMF network element is used to perform access and mobility management functions, and an SMF network element is used to perform session management functions. It may also include network elements without fixed functions, such as a UPF (User Port Function) network element used to configure specific UNI (User Network Interface) functional requirements into core functions and system management functions. That is, the functionality of the UPF network element is consistent with the user-end function of the corresponding interface. The network device may have various types of UPF network elements. In this embodiment, the network device can, based on the energy information sent by the terminal, invoke network elements associated with energy-saving services to perform communication while ensuring communication functionality, thereby reducing energy consumption during communication interaction while maintaining communication performance.

[0227] In some embodiments, the terminal is a terminal that supports energy-saving services. This terminal can be configured with an energy-saving mode, allowing normal communication between the terminal and network devices when the battery is sufficient. When the terminal's battery level falls below a certain threshold, the terminal activates the energy-saving mode and sends an energy-saving request to the network device. The network device then performs energy-saving services based on this request. The network device can achieve this by using more energy-efficient NF network elements to perform the communication process; alternatively, the network device can also modify the communication interaction process to use a simpler communication method to achieve energy savings. For example, in this embodiment, the terminal can be a small wearable device such as AR glasses. Due to the physical structure of the device, the terminal can only hold a limited amount of battery power, requiring prolonged energy-saving communication interactions. It can also be other types of terminals.

[0228] In some embodiments, energy information may be included in a request message to request the establishment of a session associated with an energy-saving service. Optionally, energy information may also be included in a notification message to report the terminal's energy information or to report that the terminal has enabled an energy-saving mode, in order to request the network device to perform an energy-saving service.

[0229] In some embodiments, triggering / requesting session establishment includes: triggering / requesting the establishment of a first session supporting energy-saving services. Energy-saving services are used to adjust the energy consumption of terminals and / or network devices. For example, energy-saving services are used to adjust the energy consumption generated by terminals and / or network devices during communication, i.e., communication energy consumption. It should be explained that the first session is a session related to energy-saving services. By executing the first session establishment procedure, the energy consumption of terminals and / or network devices can be reduced, for example, making the terminal more energy-efficient and simultaneously making the network device more energy-efficient, thereby making the overall communication system more energy-efficient. It should also be explained that executing the first session establishment procedure can reduce terminal energy consumption by lowering service quality (such as QoS), service experience, etc. This is because high service quality and service experience require high-speed data transmission, low latency, low packet loss rate, etc., and high-speed data transmission, low latency, and low packet loss correspond to high energy consumption. To reduce energy consumption, it is necessary to reduce data transmission rate, service quality, service experience, etc. The way to reduce data transmission rate, service quality, service experience, etc., is to establish a session with a lower data transmission rate, lower service quality, and lower service experience during the session establishment process.

[0230] In some embodiments, the number of first sessions is multiple, determined by the selection of a first network element and / or a second network element.

[0231] In some embodiments, the terminal can monitor the current energy information and, when it determines that the energy consumption has reached a set threshold, send energy information to the first network element and request the network device to perform energy-saving services.

[0232] In some embodiments, the terminal may also report its current energy information to the first network element during the session establishment process. This energy information can be used to instruct the terminal to support energy-saving services. The network device can then establish a session with the terminal that supports energy-saving services based on this energy information.

[0233] In some embodiments, the first network element is configured in a network device, which may be a core network device. The first network element receives an interaction request sent by a terminal and, based on the interaction request, transmits request information to other network elements in the core network device to request the other network elements in the core network device to perform the terminal's communication interaction task. In this embodiment, energy information is used to request the establishment of a session; therefore, the communication interaction task sent by the first network element to other network elements may be at least one of the following: establishing a user plane, establishing a session.

[0234] In some embodiments, the first network element may be an AMF network element. However, it is not limited to this; the first network element may also be other network elements used to receive request messages sent by the terminal.

[0235] In some embodiments, the energy information includes at least one of the following:

[0236] Battery power information;

[0237] Low battery indicator information, which is used to indicate that the terminal's battery level is below a first threshold;

[0238] Power consumption information;

[0239] High power consumption indication information is used to indicate that the terminal's power consumption is higher than a second threshold.

[0240] Energy ratio information indicates the ratio of the first energy source to the second energy source. The first energy source is the non-clean energy consumed by the terminal for communication, and the second energy source is the total energy consumed by the terminal for communication.

[0241] Energy ratio indication information is used to indicate that the energy ratio is higher than a third threshold.

[0242] For example, in this embodiment, the energy information reported by the terminal may include various types. For instance:

[0243] (1) When a terminal requests the establishment of an energy-saving service from a network device, it can send battery power information to the first network element. This battery power information is used to indicate the terminal's current remaining power.

[0244] (2) The terminal monitors the remaining battery power in real time. When it determines that the remaining battery power is below a first threshold, it sends a low battery indication message to the first network element. For example, the battery power percentage is used to indicate the battery power, where the first threshold is 20%. When the terminal determines that the remaining battery power is below 20%, it sends a first message to the first network element.

[0245] (3) The terminal reports its current power consumption information to the first network element. This power consumption information is the battery power currently consumed by the terminal. For example, the power consumption information can be indicated by the percentage of power consumption, such as 30% or 50% consumed.

[0246] (4) The terminal monitors the battery consumption and sends a high power consumption indication to the first network element when it determines that the battery consumption is higher than the second threshold. For example, the power consumption is indicated by a percentage, the second threshold is 80%, and when the terminal determines that the current power consumption is higher than 80%, the terminal sends a high power consumption indication to the first network element.

[0247] (5) The terminal reports energy ratio information to the first network element. This energy ratio is the ratio of the first energy source to the second energy source. The first energy source is the non-clean energy consumed by the communication system during the terminal's communication process, and the second energy source is the total energy consumed by the communication system during the terminal's communication process. The energy ratio information represents the energy consumed by each network node during the terminal's communication interaction. The energy consumed during communication includes the energy consumed by the terminal and the energy consumed by each network element in the network equipment.

[0248] For example, in next-generation communication technologies, to further reduce energy consumption, terminals and / or some network elements can be powered by clean energy sources in addition to electrical energy. These clean energy sources can include wind power, hydropower, and hydrogen energy, converting clean energy into electrical energy as a network element function. For instance, electrical energy generated by a wind turbine can provide energy to network element A; in this case, the energy consumed by network element A is labeled as clean energy. After completing communication interaction with the terminal, network device 1 statistically analyzes the various types of energy consumed by each network element during the communication interaction process, determines the ratio of non-clean energy consumed to total energy consumed, generates energy ratio information, and sends the energy ratio information of the communication interaction service to the terminal, or sends the clean energy consumption information and total energy consumption information of the communication interaction service to the terminal.

[0249] It should be noted that both the terminal and network devices support energy-saving services to calculate the energy consumption ratio during communication interactions. Based on this ratio, the proportion of renewable energy used in communication interactions can be adjusted. For example, network devices can use network element A to increase the proportion of clean energy used, achieving environmental protection and energy conservation.

[0250] (6) The terminal monitors the energy ratio during the communication interaction process. When the energy ratio information is detected to be higher than the third threshold, it sends energy ratio indication information to the first network element, thereby instructing the network equipment to adjust the service process and increase the consumption ratio of clean energy by using the aforementioned network element A.

[0251] Optionally, in some embodiments, the threshold information is indicated by the network device when the terminal is authorized to use the energy-saving service, or the threshold information is pre-configured on the terminal;

[0252] Among them, the energy-saving service is used to reduce the energy consumption generated by the terminal during communication, and the threshold information includes at least one of the following: a first threshold, a second threshold, and a third threshold.

[0253] For example, in this embodiment, the threshold information includes at least one of the following: a first threshold, a second threshold, and a third threshold. This threshold information may be pre-configured in the terminal; alternatively, the threshold information may also be indicated to the terminal by the network device, for example, by the network device through higher-layer signaling. The terminal monitors relevant energy parameters based on the threshold information. For example, if the threshold information is the first threshold, the terminal monitors the battery level; if the threshold information is the second threshold, the terminal monitors the power consumption; if the threshold information is the third threshold, the terminal monitors the energy ratio. When the judgment condition corresponding to the threshold information is met, the terminal reports indication information to the first network element through energy information to instruct the network device to adjust the communication interaction to a communication interaction associated with energy-saving services.

[0254] Optionally, in some embodiments, prior to step S2101 described above, the method further includes at least one of the following:

[0255] Determine that the terminal's battery level is below a first threshold;

[0256] Determine that the terminal's power consumption exceeds the second threshold;

[0257] The energy consumption ratio of the terminal is determined to be higher than the third threshold.

[0258] For example, the terminal is configured with a trigger condition for energy information. When this trigger condition is met, the terminal sends energy information to the first network element. The trigger condition includes at least one of the following:

[0259] (1) The terminal detects the battery power and when it is determined that the terminal's battery power is lower than the first threshold, it sends energy information to the first network element;

[0260] (2) The terminal detects the power consumption, and when it is determined that the power consumption of the terminal is higher than the second threshold, it sends energy information to the first network element;

[0261] (3) The terminal detects the energy ratio. When it is determined that the energy ratio of the terminal is higher than the third threshold, it sends energy information to the first network element.

[0262] In some embodiments, energy information is used to request the establishment of a session.

[0263] For example, a terminal can request to establish a session with a network device using energy information. A session refers to a series of interactions and information exchanges between communicating entities, typically involving the sending and receiving of data. The terminal can include energy information in the session establishment request to request the network device to establish a session related to energy-saving services with the terminal. For instance, this session could be a PDU session; after receiving the energy information sent by the terminal, the network device executes the PDU session establishment process for energy-saving services.

[0264] Optionally, in some embodiments, energy information may be included in any of the following messages:

[0265] Uplink NAS messages;

[0266] Registration request;

[0267] Session establishment request.

[0268] For example, when energy information is used to request the establishment of a session, this energy information can be included in the registration request or session establishment request. Optionally, this energy information can also be a power reporting message from the terminal, which sends the power reporting message to the first network to trigger the establishment of a session associated with the energy-saving service.

[0269] In step S2102, the first network element determines that the terminal is authorized to use energy-saving services based on the terminal's context or subscription data.

[0270] For example, the first network element is configured in a network device, which can be a core network device. The first network element is used to receive energy information sent by the terminal.

[0271] In some implementations, the first network element receives energy information.

[0272] For example, the first network element receives the terminal's energy information and determines from the terminal's context or subscription data whether the terminal is authorized to use energy-saving services. Alternatively, after receiving the terminal's energy information, the first network element can obtain the terminal's context or subscription data and determine whether the terminal is authorized to use energy-saving services. If it is determined that the terminal is not authorized to use energy-saving services, the first network element refuses to establish a session and sends a rejection feedback message to the terminal; if it is determined that the terminal is authorized to use energy-saving services, it means that the terminal's energy consumption can be adjusted.

[0273] In some embodiments, the context corresponding to the terminal is stored in a first network element, and the first network element determines whether the terminal is authorized to use the energy-saving service based on the stored context corresponding to the terminal. For example, if the context corresponding to the terminal contains information about the terminal subscribing to the energy-saving service, then it is determined that the terminal is authorized to use the energy-saving service. If the context corresponding to the terminal does not contain information about the terminal subscribing to the energy-saving service, then it is determined that the terminal is not authorized to use the energy-saving service.

[0274] In some embodiments, the first network element requests the terminal's subscription data from other network devices to determine whether the terminal is authorized to use the energy-saving service. For example, if the terminal's subscription data contains information about the terminal subscribing to the energy-saving service, it is determined that the terminal is authorized to use the energy-saving service. If the terminal's subscription data does not contain information about the terminal subscribing to the energy-saving service, it is determined that the terminal is not authorized to use the energy-saving service.

[0275] In some embodiments, if it is determined that the terminal is authorized to use energy-saving services based on the terminal's context or subscription data, step S2103 is executed.

[0276] In some embodiments, step S2102 may be omitted.

[0277] Optionally, in some embodiments, after step S2102 above, the method includes:

[0278] The first network element obtains the threshold information corresponding to the terminal based on the terminal's context or subscription data. The threshold information includes at least one of the following: a first threshold, a second threshold, and a third threshold.

[0279] The first network element determines, based on energy information and threshold information, that the terminal's battery level is below a first threshold; or,

[0280] The first network element determines, based on energy information and threshold information, that the terminal's power consumption exceeds the second threshold; or,

[0281] The first network element determines that the terminal's energy consumption ratio is higher than the third threshold based on energy information and threshold information.

[0282] In some embodiments, after determining that the terminal is authorized to use energy-saving services, the first network element can retrieve the terminal's threshold information from the terminal's context or subscription data. This threshold information includes at least one of the following: a first threshold, a second threshold, and a third threshold. The definition of this threshold information is the same as in the above embodiments and will not be repeated here. Based on the threshold information and the energy information reported by the terminal, the first network element determines whether the terminal currently meets the conditions for triggering energy-saving services.

[0283] For example, the energy information includes the terminal's battery level information. The first network element compares the battery level information with a first threshold. If the terminal's battery level is lower than the first threshold, it is determined that the conditions for triggering energy-saving services are met.

[0284] The energy information includes the terminal's power consumption information. The first network element compares the terminal's power consumption with a second threshold. If the terminal's power consumption is higher than the second threshold, it is determined that the conditions for triggering energy-saving services are met.

[0285] Energy information includes energy ratio information. The first network element compares the energy ratio with a third threshold. If the energy ratio of the terminal is higher than the third threshold, it is determined that the conditions for triggering energy-saving services are met.

[0286] If the energy information includes low battery indication information, then the conditions for triggering energy-saving services are determined.

[0287] If the energy information includes high power consumption indications, then the conditions for triggering energy-saving services are determined.

[0288] If the energy information includes proportional indication information, then the conditions for triggering energy-saving services are determined.

[0289] In step S2103, the first network element triggers the establishment of a first session based on the energy information, generates a second message, and sends the second message to the second network element.

[0290] In some embodiments, the second message is used by the first network element to request the establishment of the first session. The second message is generated by the first network element based on energy information when it determines that the terminal is authorized to use energy-saving services.

[0291] In some embodiments, energy information is included in a session establishment request, which can be directly used to instruct the establishment of a session. Based on this session establishment request, the first network element selects a second network element capable of providing energy-saving services to the terminal and sends the session establishment request as a second message to the second network element via transparent transmission. This second message is used by the first network element to request the second network element to provide energy-saving services to the terminal.

[0292] Optionally, in some embodiments, the energy information is included in the uplink NAS message or registration request. If the uplink NAS message or registration request cannot be directly used to indicate the establishment of a session, the first network element will generate a second message to indicate the establishment of a session based on the uplink NAS message or registration request, and send the second message to the second network element.

[0293] In some embodiments, the second message includes at least one of the following:

[0294] Terminal energy information;

[0295] Terminal identifier;

[0296] The identifier of the first session;

[0297] Energy-saving service instructions.

[0298] In some embodiments, the second network element receives a second message. The second network element includes policy control and user session management functions. The second network element is selected by the first network element; for example, the first network element selects a network element that has subscribed to the terminal's energy information change events as the second network element. For example, the first network element selects a network element that manages the terminal's policy information as the second network element. For example, the first network element selects a network element that manages the terminal's session as the second network element.

[0299] For example, the first network element performs an authorization check on the terminal based on the terminal's context or subscription data. After determining that the terminal is authorized to use energy-saving services, it compares the terminal's energy information with threshold information. When the first network element determines that the terminal meets the triggering condition corresponding to the threshold, it generates energy-saving service indication information. This energy-saving service indication information is used by the first network element to request the second network element to provide energy-saving services to the terminal. At this time, the second message includes this energy-saving service indication information.

[0300] The triggering conditions include at least one of the following:

[0301] The terminal's battery level is below the first threshold;

[0302] The terminal's power consumption exceeds the second threshold;

[0303] The terminal's energy consumption ratio is higher than the third threshold.

[0304] In step S2104, the second network element establishes the first strategy based on the second message.

[0305] In some embodiments, the second message is used to trigger the establishment of the first session.

[0306] In some embodiments, a first strategy is used to establish a first session that supports energy-saving services. The first strategy is associated with the first session, and the energy-saving services are used to reduce the energy consumption of terminals and / or network devices during communication.

[0307] For example, in this embodiment, the first strategy is a strategy related to energy-saving services. For instance, this first strategy could be an SM (Session Management) strategy. An SM strategy is a session strategy corresponding to policy management data generated by the Policy Control Function (PCF) network element. This data is used to configure various policies in the network, including QoS (Quality of Service) policies. SM strategy data contains various information about service flows, such as the type, priority, bandwidth requirements, and latency requirements of the service flows. This information is crucial for QoS control because QoS control needs to formulate corresponding strategies based on this information about the service flows to ensure that the service flows can obtain the expected quality of service. In this embodiment, the SM strategy is a strategy associated with energy-saving services. For example, an SM strategy related to energy-saving services is generated through the PCF network element. This SM strategy aims to reduce QoS to decrease energy consumption in terminals and / or network devices during communication.

[0308] In some embodiments, prior to step S2104 above, the method further includes:

[0309] The second network element determines whether the terminal is authorized to use energy-saving services based on the terminal's context or subscription data.

[0310] For example, in this embodiment, after receiving the second message, the second network element determines whether the terminal is authorized to use energy-saving services from the terminal's context or subscription data. For example, the second network element can check the terminal's context or subscription data based on the identification information to determine whether the terminal is authorized to use energy-saving services. If it is determined that the terminal is not authorized to use energy-saving services, the second network element rejects the session establishment request and sends a rejection feedback message to the terminal; if it is determined that the terminal is authorized to use energy-saving services, it means that the terminal's energy consumption can be adjusted.

[0311] In some embodiments, the second network element requests the context corresponding to the terminal from other network devices. Based on the context corresponding to the terminal, the second network element determines whether the terminal is authorized to use the energy-saving service. For example, if the context corresponding to the terminal contains information about the terminal subscribing to the energy-saving service, it is determined that the terminal is authorized to use the energy-saving service. If the context corresponding to the terminal does not contain information about the terminal subscribing to the energy-saving service, it is determined that the terminal is not authorized to use the energy-saving service.

[0312] In some embodiments, the second network element requests the terminal's subscription data from other network devices to determine whether the terminal is authorized to use the energy-saving service. For example, if the terminal's subscription data contains information about the terminal subscribing to the energy-saving service, it is determined that the terminal is authorized to use the energy-saving service. If the terminal's subscription data does not contain information about the terminal subscribing to the energy-saving service, it is determined that the terminal is not authorized to use the energy-saving service.

[0313] In some embodiments, the second network element performs step S2104 when it determines that the terminal is authorized to use energy-saving services based on the terminal's context or subscription data.

[0314] In some embodiments, the second network element, based on the terminal's context or subscription data, if it determines that the terminal is not authorized to use the energy-saving service, sends a response message to the terminal via the first network element to refuse to establish a session, and may indicate that the reason for the refusal is that the terminal has not been granted permission to use the energy-saving service.

[0315] In some embodiments, after receiving the second message, the second network element establishes the strategy required in the session.

[0316] In some embodiments, the second network element establishes a policy based on the terminal's energy information by: determining to generate / update Policy Control and Charging (PCC) rules / policies based on the terminal's energy information. When generating / updating PCC rules, the service experience, such as QoS parameters, of the corresponding terminal's service sessions / service data streams (e.g., XRM services or multimodal data) can be determined.

[0317] In some embodiments, the PCC rules are updated to reduce the power consumption of the terminal. For example, QoS adjustments are made, such as reducing the uplink Guaranteed Bit Rate (GBR) data stream bit rate.

[0318] Optionally, in some embodiments, the method further includes:

[0319] The second network element sends a third message to the third network element, and the third message includes the terminal's energy information;

[0320] The second network element receives the first rule sent by the third network element;

[0321] The second network element establishes the first strategy based on the first rule.

[0322] For example, the third network element can support a unified policy framework to manage network behavior, provide policy rules for network entities to implement, and have access to subscription information of the Unified Data Repository (UDR). In this embodiment, the third network element supports energy-saving services and can formulate rules for energy-saving services. In this embodiment, the name of the third network element is not limited; the third network element can be a PCF network element.

[0323] The second network element selects a network element that supports energy-saving services as the third network element. Various types of third network elements can be configured in the network device, including those that support energy-saving services and those that do not. The third network element supporting energy-saving services can formulate a first rule for energy-saving services, while the third network element that does not support energy-saving services cannot formulate such a first rule. Based on the second message, the second network element selects the third network element that supports energy-saving services and sends a third message to that third network element.

[0324] In this embodiment, the third network element can provide the second network element with a first rule that satisfies energy-saving services. This first rule is used to reduce the power consumption of the terminal. The third network element specifies the first rule supporting energy-saving services based on the third message. For example, the second network element is an SMF network element.

[0325] The third network element is the PCF network element. The SMF network element selects the PCF network element that supports energy-saving services based on the second message, and executes the modification or establishment process of the associated SM policy to establish or modify the SM policy associated with that PCF network element. If the SMF network element receives a low battery indication, it sends the indication to the PCF network element, which then provides PCC (Policy and Charging Control) rules to the SMF network element based on the indication, thereby reducing the terminal's power consumption.

[0326] In some embodiments, a PCC rule is a set of information elements capable of detecting service data flows and providing parameters for policy control and / or charging control, as described in related art. Therefore, updating a PCC rule is equivalent to updating a policy. In the case of a policy update, the corresponding session modification is performed.

[0327] Optionally, in some embodiments, after step S2104 above, the method further includes:

[0328] The second network element sends the first message to the terminal through the first network element.

[0329] In some embodiments, the terminal receives a first message.

[0357] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method, which includes:

[0358] Step S2201: The terminal sends energy information to the first network element.

[0359] In some embodiments, the first network element receives energy information.

[0360] In some embodiments, energy information is used for session modification.

[0361] In some embodiments, energy information may be included in a request message to request modification of a session associated with an energy-saving service, or energy information may be included in a notification message to report the terminal's energy information or to report that the terminal has enabled an energy-saving mode, in order to request the network device to perform an energy-saving service.

[0362] In some embodiments, the second message includes the terminal's energy information. The definition of the energy information is the same as in the embodiment of FIG. 2A above, and can be referred to the definition in FIG. 2A above, and will not be repeated here.

[0363] In some embodiments, the terminal can monitor the current energy information and, when it determines that the energy consumption has reached a set threshold, send energy information to the first network element and request the network device to perform energy-saving services.

[0364] In some embodiments, the terminal may also report its current energy information to the first network element, which can be used to instruct the terminal to support energy-saving services. The network device triggers session modification with the terminal based on the energy information.

[0365] For example, as the terminal's battery power is consumed, when the terminal device's energy information meets the conditions, the terminal can send energy information to the network device to request a session modification. For example, session modification can be used to adjust the path of the first session supporting energy-saving services to achieve energy saving, or it can be used to adjust relevant parameters of the first session of energy-saving services, for example, by reducing QoS to achieve energy saving.

[0366] In some embodiments, the terminal may determine the identification information of the established first session supporting energy-saving services and send the session identification information and energy information together to the first network element.

[0367] In some embodiments, the name of the energy information is not limited, and it may be, for example, "session modification request message", "energy indication information", "power indication information", etc.

[0368] Optionally, in some embodiments, energy information is included in any of the following messages:

[0369] Uplink NAS messages;

[0370] Session modification request.

[0371] For example, when energy information is used to trigger session modification, this energy information can be a NAS (Non-Access Stratum) message or a session modification request. Optionally, this energy information can also be an energy reporting message from the terminal.

[0372] In step S2202, the first network element determines that the terminal is authorized to use energy-saving services based on the terminal's context or subscription data.

[0373] The optional implementation of step S2202 can be found in the optional implementation of step S2102 in Figure 2A and other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0374] In step S2203, the first network element generates a second message based on the energy information and sends the second message to the second network element.

[0375] For example, the definition of the second network element in this embodiment is the same as the definition of the second network element in Figure 2A above. You can refer to the above embodiment, and it will not be repeated here.

[0376] In some embodiments, the second message is used to trigger a modification of the first session.

[0377] In some embodiments, the second message is used to instruct the first session modifier to execute.

[0378] In some embodiments, the first network element sends a second message to the second network element, the second message being a request for the second network element to provide energy-saving services for the terminal. Upon receiving the second message, the second network element returns a response message to the first network element, indicating whether it can provide energy-saving services for the terminal.

[0379] In some embodiments, the second message is used by the first network element to request a session modification, and the second message is generated by the first network element based on energy information.

[0380] In some embodiments, the name of the second message is not limited, and the name of the second message may be, for example, a session modification request, an energy-saving service request, etc.

[0381] Optionally, in some embodiments, the above step of "generating a second message based on energy information" includes:

[0382] The first network element determines the context of the storage terminal based on the energy information;

[0383] The first network element determines the first session based on the terminal's context;

[0384] The first network element generates the second message based on the first session.

[0385] For example, the first network element determines whether the terminal is authorized to use the energy-saving service based on the context corresponding to the terminal. For example, if the context corresponding to the terminal contains information about the terminal subscribing to the energy-saving service, then the terminal is determined to be authorized to use the energy-saving service. If the context corresponding to the terminal does not contain information about the terminal subscribing to the energy-saving service, then the terminal is determined not to be authorized to use the energy-saving service. After determining that the terminal is authorized to use the energy-saving service, the first network element checks the stored context of the terminal and determines which session to modify from the established sessions with the terminal to reduce energy consumption during communication. The modified session is the first session that supports the energy-saving service. The modification request or notification message for this first session is sent to the second network element as a second message. At this time, the second network element is the network element managing the first session.

[0386] It should be noted that the first network element can select / determine the first session. For example, the first network element selects one or more sessions belonging to the terminal that sends the first message energy information and that support energy-saving services as the first session.

[0387] For example, a terminal has multiple sessions, one or more of which are energy-saving service sessions. These energy-saving service sessions can optimize / adjust the energy consumption of the terminal and / or network equipment by establishing such sessions. The first network element selects / determines one or more of these energy-saving service sessions as the first session.

[0388] In some embodiments, if the first message does not include the identifier of the first session, the second network element may select / determine the first session.

[0389] In some embodiments, after receiving energy information sent by the terminal, the first network element retrieves the context or subscription data corresponding to the terminal to determine whether the terminal has subscribed to an energy-saving service. If it is determined that the terminal is authorized to use the energy-saving service, it can select a first session associated with the energy-saving service from multiple sessions corresponding to the terminal based on the terminal's subscription data. The network element managing this first session is then designated as the second network element.

[0390] In some embodiments, a first network element receives energy information and identification information of a first session supporting energy saving, selects the network element managing the first session as a second network element, and sends a second message to the second network element. In some embodiments, the energy information is included in a session modification request, which can be directly used to indicate session modification. Based on this session modification request, the first network element selects the second network element corresponding to the session modification request and sends the session modification request as a second message to the second network element via transparent transmission. This second message is used by the first network element to request the second network element to provide energy-saving services to the terminal.

[0391] Optionally, in some embodiments, the energy information includes an uplink NAS message. If the uplink NAS message cannot be directly used for session modification, the first network element generates a second message to indicate session modification based on the uplink NAS message and sends the second message to the second network element.

[0392] In some embodiments, the second network element receives a second message. The second network element includes session management functionality. The second network element is selected by the first network element; for example, the first network element selects a network element that has subscribed to the terminal's energy information change events as the second network element. For instance, the first network element selects a network element that has subscribed to the terminal's energy information change events and has session management functionality as the second network element.

[0393] It should be noted that for terminals subscribing to energy-saving services, the second network element can create and subscribe to the terminal's energy information change events during the terminal registration process. Once the first network element receives the terminal's energy information change event, it sends a second message to the corresponding second network element.

[0394] In some embodiments, the number of first sessions is multiple, determined by the selection of a first network element and / or a second network element.

[0395] In some embodiments, the first session may be selected by a first network element, and the first network element may indicate the selected / confirmed first session to a second network element. For example, the first network element may include the identifier of the selected / confirmed first session in a second message and send it to the second network element. For example, the first network element may send the identifier of the selected / confirmed first session to the second network element separately. This disclosure does not limit the manner in which the first network element indicates the first session to the second network element.

[0396] It should be noted that when energy information is used for session modification, the first network element selects / determines the first session and instructs the second network element to select / determine the first session. When energy information is used for session establishment, the first network element establishes the first session associated with the energy-saving service.

[0397] In some embodiments, in addition to the first network element selecting / determining the first session, the second network element may also select / determine the first session. For example, the second network element selects one or more sessions belonging to the terminal and supporting energy-saving services as the first session based on the terminal identifier in the second message.

[0398] The terminal can have multiple sessions, one or more of which can be sessions supporting energy-saving services. These energy-saving service-supporting sessions can optimize / adjust the energy consumption of the terminal and / or network equipment by modifying the sessions. The second network element can select / determine one or more of these energy-saving service-supporting sessions as the first session.

[0399] It should be noted that in this embodiment, the energy information reported by the terminal is used to request and trigger session modification. However, during the process of sending the request, the terminal does not know which specific session needs to be modified. After receiving the session modification request, the first network element determines the first session to be modified by consulting the terminal's context or subscription data. This first session is a specific session type. For example, the terminal sends a PDU session modification request to the first network element. Based on the terminal's context and subscription data, the first network element selects the first PDU session associated with the energy-saving service from the stored PDU session contexts as the session to be modified.

[0400] In some embodiments, the energy information reported by the terminal is used to request a session modification. The terminal identifies a first session that supports energy-saving services and provides the identifier of the first session to a first network element and / or a second network element. For example, the terminal sends a PDU session modification request to the first network element, which includes the identifier of the first session that supports energy-saving services and the terminal's energy information. The first network element then provides the identifier of the first session and the terminal's energy information to the second network element.

[0401] In step S2204, the second network element modifies the first strategy based on the first energy information of the nodes on the user plane path.

[0402] For example, after receiving the second message, the second network element can check the terminal's context or subscription data to determine whether the terminal is authorized to use the energy-saving service. If the second network element detects that the terminal is not authorized to use the energy-saving service, it sends a feedback message rejecting the session modification request to the terminal through the first network element. If the second network element determines that the terminal is authorized to use the energy-saving service based on the context and subscription data, it initiates the modification procedure for the first policy.

[0403] In some embodiments, the second network element requests the context corresponding to the terminal from other network devices. Based on the context corresponding to the terminal, the second network element determines whether the terminal is authorized to use the energy-saving service. For example, if the context corresponding to the terminal contains information about the terminal subscribing to the energy-saving service, it is determined that the terminal is authorized to use the energy-saving service. If the context corresponding to the terminal does not contain information about the terminal subscribing to the energy-saving service, it is determined that the terminal is not authorized to use the energy-saving service.

[0404] In some embodiments, the second network element requests the terminal's subscription data from other network devices to determine whether the terminal is authorized to use the energy-saving service. For example, if the terminal's subscription data contains information about the terminal subscribing to the energy-saving service, it is determined that the terminal is authorized to use the energy-saving service. If the terminal's subscription data does not contain information about the terminal subscribing to the energy-saving service, it is determined that the terminal is not authorized to use the energy-saving service.

[0405] In some embodiments, the second network element performs step S2204 based on the terminal's context or subscription data, if it determines that the terminal is authorized to use energy-saving services.

[0406] In some embodiments, the second network element, based on the terminal's context or subscription data, if it determines that the terminal is not authorized to use the energy-saving service, sends a response message to the terminal via the first network element to refuse session modification, and may indicate that the reason for the refusal is that the terminal has not been granted permission to use the energy-saving service.

[0407] In some embodiments, after receiving the second message, the second network element can trigger session modification by updating the policy.

[0408] In some embodiments, updating the first policy based on the second message may include: triggering an update of Policy Control and Charging (PCC) rules / policies based on the terminal's energy information in the second message. In the case of updating PCC rules, the service experience of the corresponding terminal's service sessions / service data streams (e.g., XRM services or multimodal data), such as QoS parameters, may be updated.

[0409] In some embodiments, the second network element may invoke first energy information of each node on the UP (User Plane) path. These nodes may be UPF (User Plane Function) nodes. The second network element filters from multiple UPF nodes to select those matching the session type requested by the terminal, and then selects UPF nodes that can reduce terminal power consumption based on the first energy information. For example, the first energy information indicates the energy consumption of each node on the UP path, and the second network element selects UPF nodes that can reduce the power consumption of the terminal and / or network devices from multiple UPF nodes to implement the modification of the first strategy.

[0410] The second network element can decide to update the user plane UP path. For affected v-UPF nodes, the second network element (e.g., v-SMF) can execute the N4 session establishment / modification procedure. In the case of a user plane path update in the first session, the first session update needs to be executed.

[0411] Optionally, in some embodiments, the first energy information is provided by a fourth network element, or the first energy information is pre-stored on a second network element, wherein the fourth network element is used to monitor or collect energy information of each network node. Optionally, the name of the fourth network element is not limited, and the name of the fourth network element 1024 may be, for example, an Energy Control Function (ECF) network element or an Energy Information Function (EIF) network element.

[0412] For example, during the process of the second network element acquiring the first energy information, it can call the energy collection service provided by the fourth network element, which will then send the first energy information of each node on the UP path to the second network element. Optionally, during the process of establishing the UP path corresponding to the terminal, each UPF network element can report the first energy information to the second network element, and the second network element can store the second energy information locally.

[0413] In some embodiments, the energy-saving service requested by the terminal can also be the energy-saving service requested by the terminal during roaming. For example, the second network element can be a v-SMF (Visited Service Management Function) network element. When the v-SMF network element receives a session modification request, the v-SMF can send a session modification request to the h-SMF (Home Service Management Function) network element, which includes the terminal's energy information or low battery indication information.

[0414] Based on the received session modification request, the h-SMF can determine whether the terminal has subscribed to the energy-saving service according to the terminal's context or subscription data. If the terminal is authorized to use the energy-saving service, it triggers the modification of the first policy. For example, if the h-SMF determines that the terminal has subscribed to the energy-saving service, it reports an energy efficiency event to the h-PCF network element to trigger the h-PCF network element to send the first rule associated with the energy-saving service to the h-SMF network element. The h-SMF network element can invoke the energy harvesting service operation provided by the h-ECF network element to obtain energy-related information of the h-UPF node. The h-SMF network element determines the updated UP path based on the first rule and / or energy information. After the UP path is updated, the h-SMF network element sends a session modification response to the v-SMF network element, which includes the updated UP path channel information and the first policy. After receiving the session modification response, the v-SMF network element determines how to update the UP path. Based on the updated first policy and / or energy information, the v-SMF network element can determine the UP path that needs to be updated and sends a PDU session update response back to the AMF network element.

[0527] Figure 7A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 7A, the embodiments of the present disclosure relate to a communication method, which includes:

[0528] 1. The UE sends a PDU session establishment request to the AMF, and the establishment request includes the UE's battery level.

[0529] 2. The AMF selects an SMF for this PDU session.

[0530] 3. The AMF invokes the SM_context_create (SM create context) service operation. For example, if the UE has subscribed to an energy service, the AMF retrieves the battery level threshold from the UE's subscription data. If the battery level is below the threshold, the AMF sends a low battery indication to the SMF to establish a PDU session.

[0531] In some embodiments, if the PDU session is an energy efficiency-related PDU session, the SMF may subscribe to the UE battery power information from the AMF.

[0532] 4. The SMF can select a PCF and execute the procedure for establishing / modifying the associated SM policy to establish / modify the SM policy associated with that PCF. If the SMF receives a low battery indication, the SMF will instruct the PCF to do so. The PCF will then provide PCC rules based on this indication, thereby further extending the UE's battery life.

[0533] 5. Execute the PDU session establishment procedure.

[0534] Figure 7B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 7B, the present disclosure relates to a communication method, which includes:

[0535] 1. When the UE's battery level is lower than the battery level threshold, the UE sends a PDU session modification request, or a UL-NAS message (Uplink NAS Transport, such as 5G MM (Mobility Management) status, UL NAS transmission, etc.) or a registration request to the AMF. The UE's battery level information or low battery indication is included in the message.

[0536] In some embodiments, the battery power threshold is provided by the CN (Core Network) during the service license period.

[0537] 2. If a UL NAS message is received, the AMF can determine whether to update the PDU session to modify the service experience. The AMF can also check the UE subscription data to determine whether the UE has subscribed to the energy efficiency service.

[0538] In some embodiments, if the authorization check fails, the AMF will reject the request. Otherwise, the AMF will retrieve the stored PDU session context to determine which PDU session can be modified to save UE battery life, and send a PDU session update request or notification message to the SMF managing the selected PDU session.

[0539] In some embodiments, if a PDU session modification request is received, the AMF will send a PDU session update request to the SMF. UE battery level information or low battery indication is included in the PDU session update request.

[0540] In some embodiments, the AMF can determine the SMF that subscribes to the UE battery power information and send a notification message to the selected SMF. The SMF can subscribe to the UE battery power information during the PDU session establishment process.

[0541] 3. Based on the received UE battery power information or low battery indication, the SMF determines whether to trigger the SM policy association modification procedure initiated by the SMF.

[0542] For example, the SMF can check the UE's subscription data to determine if the UE has subscribed to energy efficiency services. If the check fails, the SMF will reject the request. This step can be skipped if energy consumption can be improved without changing the SM policy, or if the conditions for subscribing to energy efficiency events are not met. Otherwise, the SMF may need to report the energy efficiency event to the PCF by executing the SMF-initiated SM policy association modification procedure defined in TS23.502. The SMF can obtain the latest policy information about the PDU session from the PCF.

[0543] 4. The SMF can invoke the energy harvesting service provided by the ECF to obtain energy-related information of managed UPF nodes and / or suggested UPF nodes to improve energy efficiency. This step can be skipped if the energy information is already stored locally.

[0544] 5. Based on the updated policy and / or energy information, the SMF can decide to update the UP path. For affected UPF nodes, the SMF can execute the N4 session establishment / modification procedure.

[0545] 6. The SMF returns a PDU session update response message to the AMF.

[0546] 7. The AMF sends a PDU session modification response or a DL-NAS message to the UE.

[0547] Figure 7C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 7C, the embodiments of the present disclosure relate to a communication method, which includes:

[0548] 1. When the UE's battery level is below a threshold, the UE sends a PDU session modification request or a UE battery level report to the AMF. The UE battery level information or low battery level indication is included in the message.

[0549] 2. If a UL NAS message is received, the AMF can determine whether to update the PDU session to modify the service experience. The AMF can also check the UE subscription data to determine whether the UE has subscribed to the energy efficiency service.

[0550] For example, if the check fails, the AMF rejects the request. Otherwise, the AMF retrieves the stored PDU session context to determine which PDU session can be modified to save UE battery life and sends a PDU session update request / notification to the SMF that manages the selected PDU session.

[0551] In some embodiments, if a PDU session modification request is received, the AMF will send a PDU session update request to the v-SMF. UE battery level information or low battery indication is included in the PDU session update request.

[0552] 3. After receiving the PDU session update request, the v-SMF can send an SM context update request to the h-SMF, which includes UE battery power information or low battery indication.

[0553] 4. h-SMF determines whether to trigger the SM policy association modification procedure initiated by SMF based on the received UE battery power information or low battery power indication.

[0554] For example, the h-SMF can check UE subscription data to determine if the UE has subscribed to energy efficiency services. If the check fails, the h-SMF will reject the request. If energy consumption can be improved without changing the SM policy and the conditions for subscribing to energy efficiency events are not met, this step can be skipped. The h-SMF can adjust the UP path to meet energy efficiency requirements. Otherwise, the h-SMF may need to report energy efficiency events to the h-PCF by executing the SMF-initiated SM policy association modification procedure defined in TS 23.502. The h-SMF can obtain the latest policy information about the PDU session from the PCF.

[0555] 5. h-SMF can invoke the energy harvesting service provided by h-ECF to obtain energy-related information for modifying and / or suggesting h-UPF nodes to improve energy efficiency. This step can be skipped if the energy information is already stored locally.

[0556] 6. Based on updated policy and / or energy information, h-SMF can determine to update the UP path. For affected h-UPF nodes, h-SMF can execute the N4 session establishment / modification procedure.

[0557] 7. h-SMF sends SM context update response information to v-SMF, including updated H-CN channel information and updated SM policy (optional).

[0558] 8. Once v-SMF receives the SM context update response, it can determine how to update the UP path.

[0559] For example, v-SMF can invoke the energy harvesting service provided by v-ECF to obtain energy-related information for managed v-UPF nodes and / or suggest v-UPF nodes, thereby improving energy efficiency. This step can be skipped if the energy information is already stored locally.

[0560] 9. Based on the updated SM policy information and / or energy information, v-SMF can determine to update the UP path. For affected v-UPF nodes, v-SMF can execute the N4 session establishment / modification procedure.

[0561] 10. v-SMF returns a PDU session update response to AMF.

[0562] 11. The AMF sends a PDU session modification response or a DL NAS message to the UE.

[0563] 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.

[0564] 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. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. 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.

[0565] 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).
