[0052] FIG2 is a schematic diagram of an energy efficiency or energy consumption optimization method provided in an embodiment of the present application. As shown in FIG2 , the energy efficiency or energy consumption optimization method may include the following steps S201 and S202:

[0053] Step S201: A first network element obtains first information.

[0054] The first information mentioned above includes information related to energy consumption of the network element.

[0055] In some embodiments of the present application, the energy consumption related information of the network element includes at least one of the following:

[0056] Energy consumption information of the first network element;

[0064] It can be understood that the energy consumption and energy efficiency of a network element are indicators that evaluate the amount of energy or resources consumed by the network element during operation. The energy consumption and energy efficiency of a network element can be calculated based on the amount of data transmitted per unit time with a specific energy consumption.

[0065] In some embodiments of the present application, the above-mentioned first network element may be AMF, SMF or UPF, and the above-mentioned second network element may be AMF, SMF or UPF.

[0066] In some embodiments of the present application, the first network element and the second network element may be the same network element or different network elements.

[0067] Exemplarily, the first network element may be the first AMF, and the second network element may be the first AMF; or, the first network element may be the first AMF, and the second network element may be the first SMF; or, the first network element may be the first SMF, and the second network element may be the first SMF; or, the first network element may be the first SMF, and the second network element may be the first UPF; or, the first network element may be the first UPF, and the second network element may be the first UPF.

[0068] It should be noted that the above-mentioned first network element or second network element can also be other network elements in the communication network that need to save energy, and the embodiments of the present application are not limited to this.

[0069] It can be understood that when the first network element and the second network element are the same network element (i.e., the same network element), the first network element obtains its own energy consumption related information, or when the first network element and the second network element are different network elements, the first network element obtains energy consumption related information of other network elements different from itself.

[0070] In some embodiments of the present application, the first network element may obtain the first information from a fourth network element, where the fourth network element may include at least one of the following: OAM, EENF, NWDAF, SMF, UPF, and PCF.

[0071] In some embodiments of the present application, the first information further includes at least one of the following:

[0072] First network element reselection indication;

[0073] Second network element reselection indication;

[0074] Network energy saving instructions or network energy saving strategy information.

[0075] In some embodiments, the first network element reselection indication is used to indicate the selection or reselection of a network element whose energy consumption information is less than or equal to a first threshold, or the first network element reselection indication is used to indicate the reselection of a network element whose energy efficiency information is greater than or equal to a second threshold.

[0076] In some embodiments, the second network element reselection indication is used to indicate the selection or reselection of a network element whose energy consumption information is less than or equal to a third threshold, or the second network element reselection indication is used to indicate the reselection of a network element whose energy efficiency information is less than or equal to a fourth threshold.

[0077] In some embodiments, the above-mentioned network energy saving indication is used to indicate the execution of network energy saving, or the network energy saving indication is used to indicate the selection or reselection of a network element whose energy consumption information is less than or equal to a fifth threshold, or to indicate the selection or reselection of a network element whose energy efficiency information is greater than or equal to a sixth threshold.

[0078] In some embodiments, the network energy saving policy information is used to perform energy saving operations.

[0079] In some embodiments of the present application, the above-mentioned first network element reselection indication may include the reason for reselection, which may be network energy saving or energy efficiency optimization; the above-mentioned second network element reselection indication may include the reason for reselection, which may be network energy saving or energy efficiency optimization.

[0080] Step S202: The first network element performs a first operation related to energy saving according to the first information.

[0081] In some embodiments of the present application, the first network element performs a first operation related to energy saving when obtaining at least one of the following: information indicating that the energy consumption of the first network element is greater than or equal to a first threshold, information indicating that the energy efficiency of the first network element is less than or equal to a second threshold, information indicating that the energy consumption of the second network element is greater than or equal to a third threshold, and information indicating that the energy efficiency of the second network element is less than or equal to a fourth threshold.

[0082] In some embodiments of the present application, when the first network element obtains at least one of the energy consumption information of the first network element, the energy efficiency information of the first network element, the energy consumption information of the second network element, and the energy efficiency information of the second network element, it can determine whether the energy consumption information of the network element is greater than a predetermined threshold or whether the energy efficiency information of the network element is less than a predetermined threshold, and perform a first operation related to energy saving when the energy consumption information of the network element is greater than the predetermined threshold or the energy efficiency information of the network element is less than the predetermined threshold.

[0083] It can be understood that the above network element can be at least one of the first network element and the second network element.

[0084] In some embodiments of the present application, the first network element performs a first operation related to energy saving when obtaining at least one of a first network element reselection indication, a second network element reselection indication, a network energy saving indication, or network energy saving policy information.

[0085] In an energy efficiency or energy consumption optimization method provided in an embodiment of the present application, a first network element obtains first information, the first information including information related to the network element's energy consumption, and the first network element performs a first operation related to energy saving based on the first information. Through this method, the first network element can perform the first operation related to energy saving based on the network element's energy consumption information, thereby optimizing the energy efficiency or energy consumption of the network, avoiding resource waste caused by high energy consumption resulting from network elements participating in communications when energy consumption is high or energy efficiency is low, thereby saving network resources.

[0086] In some embodiments of the present application, the above step S202 may be implemented by the following step S202a:

[0087] Step S202a: When the first network element meets the first condition or the second network element meets the second condition, the first network element performs a first operation related to energy saving.

[0088] Among them, the above-mentioned first condition includes: the energy consumption information of the first network element is greater than or equal to the first threshold, or the energy efficiency information of the first network element is less than or equal to the second threshold; the above-mentioned second condition includes: the energy consumption information of the second network element is greater than or equal to the third threshold, or the energy efficiency information of the second network element is less than or equal to the fourth threshold.

[0089] In some embodiments, when the first information includes energy consumption-related information of the first network element, the first network element may determine whether the first network element meets the first condition based on the energy consumption-related information of the first network element; or, when the first information includes energy consumption-related information of the second network element, the first network element may determine whether the second network element meets the second condition based on the energy consumption-related information of the second network element.

[0090] For example, taking the first network element as AMF and the second network element as AMF as an example, when the energy consumption of the AMF itself exceeds a predetermined value or the energy efficiency is lower than a predetermined value, the AMF performs a first operation related to energy saving.

[0091] For example, taking the first network element as AMF and the second network element as SMF as an example, when the AMF obtains that the energy consumption of the SMF exceeds a predetermined value or the energy efficiency is lower than a predetermined value, the AMF performs a first operation related to energy saving.

[0092] Exemplarily, taking the first network element as SMF and the second network element as SMF as an example, when the SMF obtains that its own energy consumption exceeds a predetermined value or its energy efficiency is lower than a predetermined value, it performs a first operation related to energy saving.

[0093] For example, taking the first network element as SMF and the second network element as UPF as an example, when the SMF obtains that the energy consumption of the UPF exceeds a predetermined value or the energy efficiency is lower than a predetermined value, the SMF performs a first operation related to energy saving.

[0094] Exemplarily, taking the first network element as UPF and the second network element as UPF as an example, when the UPF obtains that its own energy consumption exceeds a predetermined value or its energy efficiency is lower than a predetermined value, it performs a first operation related to energy saving.

[0095] In an embodiment of the present application, the first network element can perform a first energy-saving-related operation when it is obtained that its own energy consumption exceeds a predetermined value or its energy efficiency is lower than a predetermined value, or when it is obtained that the energy consumption of a second network element exceeds a predetermined value or its energy efficiency is lower than a predetermined value, to optimize the energy consumption or energy efficiency of the network element, thereby saving network resources.

[0096] In some embodiments of the present application, the first network element is an AMF, and step S202 may include at least one of the following steps A1 and A2:

[0097] Step A1: upon receiving a registration request message from a user equipment (UE), the first network element sends a registration request message to a third network element.

[0098] The network element type of the third network element is the same as the network element type of the first network element.

[0099] Step A2: The first network element sends a deregistration request message to the UE.

[0100] In some embodiments, when the first network element is an AMF and the first network element satisfies the first condition, or the first information includes at least one of indication information indicating that the energy consumption information of the first network element is greater than or equal to a first threshold, indication information indicating that the energy efficiency information of the first network element is less than or equal to a second threshold, a first network element reselection indication, a network energy saving indication, and network energy saving strategy information, the above-mentioned step S202 may include at least one of the above-mentioned steps A1 and A2.

[0101] The first condition includes: the energy consumption information of the first network element is greater than or equal to a first threshold, or the energy efficiency information of the first network element is less than or equal to a second threshold.

[0102] In some possible implementations, when the first network element receives a registration request from the UE and the first network element meets the first condition, the first network element may forward the registration request to a third network element, so that the UE can register on the third network element.

[0103] In some embodiments, the third network element satisfies a third condition, which includes at least one of the energy consumption information of the third network element being less than or equal to a fifth threshold, or the energy efficiency information of the third network element being greater than or equal to a sixth threshold.

[0104] For example, taking the first network element as the first AMF and the third network element as the second AMF as an example, when the first AMF receives a registration request message from the UE, if the first AMF meets the first condition, it forwards the registration request message to the third AMF to select or reselect an AMF with lower energy consumption or higher energy efficiency for the UE to register.

[0105] In some possible implementations, when the first network element receives a registration request from a UE and receives at least one of a first network element reselection indication, indication information indicating that the energy consumption information of the first network element is greater than or equal to a first threshold, indication information indicating that the energy efficiency information of the first network element is less than or equal to a second threshold, a network energy saving indication, and network energy saving policy information, the first network element may forward the registration request to a third network element so that the UE can register on the third network element.

[0106] After the above step A1, the third network element may receive the registration request message from the first network element and execute the registration process.

[0107] In some possible implementations, when the first condition is met, the first network element sends a deregistration request message to the UE to deregister the UE, thereby saving network resources.

[0108] It can be understood that the above deregistration request message can be used to request deregistration of the UE.

[0109] In some possible implementations, when the first network element receives at least one of a first network element reselection indication, a network energy saving indication, and network energy saving policy information, if it determines that it meets the first condition, it sends a deregistration request message to the UE to deregister the UE, thereby saving network resources.

[0110] For example, taking the first network element as the first AMF as an example, when the first AMF receives at least one of the first network element reselection indication, the network energy saving indication and the network energy saving policy information, if the first AMF meets the first condition, it sends a deregistration request message to the UE to perform deregistration on the UE, so as to avoid the first AMF from participating in communication under high energy consumption or low energy efficiency, thereby saving network resources.

[0111] In some embodiments of the present application, the deregistration request message includes at least one of the following:

[0112] Indicative information indicating the energy consumption or energy efficiency reason for performing the deregistration;

[0113] Instructions for performing a re-registration.

[0114] In some embodiments, the above energy consumption or energy efficiency reasons may be network energy saving or energy efficiency optimization, etc.

[0115] In some embodiments, when the de-registration request message includes indication information indicating re-registration, the UE can initiate re-registration, that is, re-send the registration request message to the first network element. The first network element can receive the registration request message of the first network element and forward the registration request message to the third network element to perform network element reselection, that is, redirect to the third network element.

[0116] In an embodiment of the present application, when the first network element has high energy consumption or low energy efficiency, it achieves network energy saving and improves energy efficiency by reselecting network equipment with low energy consumption and high energy efficiency.

[0117] In some embodiments of the present application, before the first network element sends the registration request message to the third network element in step A1 above, the energy efficiency or energy consumption optimization method provided in the embodiment of the present application may include the following step S203:

[0118] Step S203: The first network element obtains the third network element.

[0119] In some embodiments, the first network element may obtain the third network element from the fourth network element.

[0120] It should be noted that the explanation of the fourth network element can be found above and will not be repeated here.

[0121] For example, taking the first network element as AMF and the fourth network element as OAM, AMF can query OAM for a target AMF (i.e., the third network element) that meets the third condition (i.e., low energy consumption and high energy efficiency); or, AMF first queries OAM for an AMF list, which includes one or more AMF identifiers, and then sends the AMF list to OAM, and obtains a target AMF that meets the third condition from the AMF list from OAM.

[0122] In some embodiments of the present application, the first network element is an SMF, and step S202 may include at least one of the following steps B1 to B3:

[0123] Step B1: The first network element sends the first information to the AMF.

[0124] The first information includes a second network element reselection indication, and the second network element reselection indication is used to indicate the reselection of the SMF.

[0125] Step B2: The first network element sends a PDU session release command to the UE.

[0126] Step B3: The first network element sends a PDU session modification command to the UE.

[0127] In some embodiments, when the first network element satisfies the first condition, or the first information includes at least one of indication information indicating that the energy consumption information of the first network element is greater than or equal to a third threshold, indication information indicating that the energy efficiency information of the first network element is less than or equal to a fourth threshold, a second network element reselection indication, a network energy saving indication, and network energy saving strategy information, the above-mentioned step S202 may include at least one of the above-mentioned steps B1 to B3.

[0128] The first condition mentioned above includes: the energy consumption information of the first network element is greater than or equal to a first threshold, or the energy efficiency information of the first network element is less than or equal to a second threshold.

[0129] In some possible implementations, when the SMF obtains that its own energy consumption exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value, or the energy efficiency is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF, or an energy efficiency optimization notification, or an indication to reselect a network device, it sends a network element reselection indication to the AMF to instruct the execution of SMF reselection. The AMF can receive the network element reselection indication sent by the SMF and reselect the SMF according to the network element reselection indication, thereby selecting a SMF with lower energy consumption or higher energy efficiency for communication.

[0130] In some possible implementations, when the SMF obtains that its own energy consumption exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value, or the energy efficiency is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF, or an energy efficiency optimization notification, or an indication to reselect a network device, it sends a PDU session release command to the UE to instruct the release of the PDU session between the SMF and the UE, thereby avoiding the SMF from continuing to participate in the communication and generating more resource consumption.

[0131] In some possible implementations, when the SMF obtains that its own energy consumption exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value, or the energy efficiency is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF, or an energy efficiency optimization notification, or an indication to reselect a network device, it sends a PDU session modification command to the UE to instruct the reconstruction of the PDU session between the UE and the SMF, thereby avoiding the SMF from continuing to participate in the communication and generating more resource consumption.

[0132] It can be understood that the PDU session modification command may be a PDU session reconstruction command, and may be used to instruct the reconstruction of the PDU session.

[0133] In some embodiments of the present application, the above-mentioned PDU session release command carries at least one of the indication information indicating the re-establishment of the PDU session and the indication information indicating the energy consumption or energy efficiency reason for the release of the PDU session; and / or, the above-mentioned PDU session modification command carries at least one of the indication information indicating the re-establishment of the PDU session and the indication information indicating the energy consumption or energy efficiency reason for the PDU session modification.

[0134] In some embodiments of the present application, the second network element reselection indication may include at least one item of indication information indicating the energy consumption or energy efficiency reason for the reselection.

[0135] In some embodiments, when the PDU session release command carries indication information indicating re-establishment of the PDU session, the UE may re-initiate the PDU session establishment request according to the indication information.

[0136] Exemplarily, the UE can send a PDU session establishment request to the AMF. Upon receiving the PDU session establishment request from the UE, the AMF selects an SMF with lower energy consumption or an SMF with higher energy efficiency to establish a PDU session based on the second network element reselection indication.

[0137] In some embodiments of the present application, the first network element is an AMF, and the above step S202 may include the following steps C1:

[0138] Step C1: upon receiving a PDU session establishment request from the UE, the first network element sends the PDU session establishment request to the third network element.

[0139] The network element type of the third network element is the same as the network element type of the second network element.

[0140] In some embodiments, when the second network element satisfies the second condition, or the first information includes a second network element reselection indication, indication information indicating that the energy consumption information of the second network element is greater than or equal to a third threshold, and indication information indicating that the energy efficiency information of the second network element is less than or equal to a fourth threshold, the above-mentioned step S202 may include the above-mentioned step C1.

[0141] Among them, the above-mentioned second condition includes: the energy consumption information of the second network element is greater than or equal to the third threshold, or the energy efficiency information of the second network element is less than or equal to the fourth threshold, and the above-mentioned first network element reselection indication is used to indicate the reselection of SMF.

[0142] In some embodiments, the second network element may be a first SMF, and the second network element may be a second SMF. For example, when the AMF receives a PDU session establishment request from the UE and the first SMF meets the second condition, the AMF sends a PUU session establishment request to the second SMF to establish a PDU session with the second SMF.

[0143] In some embodiments, the second network element may be a first SMF, and the second network element may be a second SMF. For example, when the AMF receives a PDU session establishment request from the UE and the first SMF meets the second condition, the AMF sends a PDU session establishment request to the second SMF to request establishment of a PDU session with the second SMF.

[0144] In some embodiments, the above-mentioned second network element may be a first SMF, and the above-mentioned second network element may be a second SMF. For example, when the AMF receives a PDU session establishment request from the UE, and the AMF receives a second network element reselection indication, indication information indicating that the energy consumption information of the first SMF is greater than or equal to the third threshold, and indication information indicating that the energy efficiency information of the first SMF is less than or equal to the fourth threshold, the AMF sends the PUU session establishment request to the second SMF to establish a PDU session with the second SMF. In this way, when the energy consumption of the first SMF currently participating in the communication is high or the energy efficiency is low, the AMF can select a second SMF with lower energy consumption or higher energy efficiency, and send a PDU session establishment request to the second SMF to establish a PDU session with the second SMF, so that the SMF with lower energy consumption or higher energy efficiency can be selected to participate in the communication, thereby saving network resources.

[0145] In some embodiments of the present application, before the first network element sends the PDU session establishment request to the third network element in the above step C1, the energy efficiency or energy consumption optimization method provided in the embodiment of the present application may include the following step S204:

[0146] Step S204: The first network element obtains the third network element.

[0147] In some embodiments, the first network element may obtain the third network element upon receiving a PDU session establishment request from the UE, and establish a PDU session with the third network element.

[0148] In some embodiments, the first network element may obtain the third network element from the fourth network element. For example, taking the first network element as an AMF, the AMF may obtain the third network element from the fourth network element.

[0149] In some embodiments of the present application, the first network element is an SMF, and the above step S202 may include at least one of the following steps D1 to D3:

[0150] Step D1: The first network element sends a PDU session release command to the UE.

[0151] Step D2: The first network element sends a PDU session modification command to the UE.

[0152] Step D3: Upon receiving the PDU session establishment request from the UE, the first network element establishes a PDU session with the third network element.

[0153] The network element type of the third network element is the same as the network element type of the second network element.

[0154] In some embodiments, when the second network element satisfies the second condition, or the first information includes at least one of a second network element reselection indication, indication information indicating that the energy consumption information of the second network element is greater than or equal to a third threshold, and indication information indicating that the energy efficiency information of the second network element is less than or equal to a fourth threshold, the above-mentioned step S202 may include at least one of the following steps D1 to D3.

[0155] Among them, the above-mentioned second condition includes: the energy consumption information of the second network element is greater than or equal to the third threshold, or the energy efficiency information of the second network element is less than or equal to the fourth threshold, and the second network element reselection indication is used to indicate the reselection of UPF.

[0156] In some embodiments, upon receiving a PDU session establishment request from the UE, the first network element may establish an N4 session with the third network element.

[0157] In some embodiments, the PDU session release command is used to instruct the release of the PDU session with the second network element.

[0158] In some embodiments, the above-mentioned PDU session modification command is used to instruct modification or reconstruction of a PDU session.

[0159] In some embodiments, the second network element may be a first UPF, and the second network element may be a second UPF. For example, if the first UPF satisfies the second condition, the SMF may send a PDU session release command to the UE to release the PDU session between the UE and the first UPF, thereby preventing the first UPF from continuing to participate in communications when energy consumption is high or energy efficiency is low; or, if the first UPF satisfies the second condition, the SMF may send a PDU session modification command to the UE to reestablish the PDU session between the UE and the UPF, thereby preventing the first UPF from continuing to participate in communications when energy consumption is high or energy efficiency is low, thereby saving resources.

[0160] In some embodiments, the second network element may be a first UPF, and the second network element may be a second UPF. For example, when the SMF receives a PDU session establishment request from the UE and the first UPF satisfies the second condition, it sends a PUU session establishment request to the second UPF to establish an N4 session with the second UPF.

[0161] In some embodiments, the second network element may be a first UPF, and the second network element may be a second UPF. For example, when the SMF receives a PDU session establishment request from the UE and the first UPF satisfies the first condition, the SMF establishes an N4 session with the second UPF. In this way, if the first UPF currently participating in the communication has high energy consumption or low energy efficiency, the SMF can select a second UPF with lower energy consumption or higher energy efficiency and establish an N4 session with the second UPF, thereby being able to select a UPF with lower energy consumption or higher energy efficiency to participate in the communication, thereby saving network resources.

[0162] In some embodiments, the second network element may be a first UPF, and the second network element may be a second UPF. For example, when the SMF receives a PDU session establishment request from the UE, and the SMF receives a second network element reselection indication, indication information indicating that the energy consumption information of the first UPF is greater than or equal to a third threshold, and indication information indicating that the energy efficiency information of the first UPF is less than or equal to a fourth threshold, the SMF establishes an N4 session with the second UPF. In this way, when the energy consumption of the first UPF currently participating in the communication is high or the energy efficiency is low, the SMF can select a second UPF with lower energy consumption or higher energy efficiency, and establish an N4 session with the second UPF, so that the UPF with lower energy consumption or higher energy efficiency can be selected to participate in the communication, thereby saving network resources.

[0163] In some embodiments of the present application, after the first network element establishes a PDU session with the third network element, the first information obtained may be deleted. For example, the SMF may delete the energy consumption related information obtained of the first UPF, thereby avoiding the subsequent inability to select the second network element.

[0164] In some embodiments of the present application, before the first network element establishes a PDU session with the third network element in step D3, the energy efficiency or energy consumption optimization method provided in the embodiment of the present application may include the following step S205:

[0165] Step S205: The first network element obtains the third network element.

[0166] In some embodiments, taking the first network element as SMF as an example, the SMF can obtain the third network element from the fourth network element.

[0167] It should be noted that the explanation of the fourth network element can be found above and will not be repeated here.

[0168] In some embodiments of the present application, the above-mentioned PDU session release command carries at least one of the indication information indicating the re-establishment of the PDU session and the indication information indicating the energy consumption or energy efficiency reason for the release of the PDU session; and / or, the above-mentioned PDU session modification command carries at least one of the indication information indicating the re-establishment of the PDU session and the indication information indicating the energy consumption or energy efficiency reason for the PDU session modification.

[0169] In some embodiments, when the PDU session release command carries at least one of indication information indicating the re-establishment of the PDU session and indication information indicating the energy consumption or energy efficiency reason for the release of the PDU session, the UE can re-initiate the PDU session establishment process, and the SMF can select a second UPF with low energy consumption or high energy efficiency to establish an N4 session during the PDU session establishment process.

[0170] In some embodiments of the present application, the first network element is a UPF, and the above step S202 may include the following steps E1:

[0171] Step E1: The first network element sends first information to the SMF.

[0172] The first information includes at least one of the following:

[0173] Energy consumption information of the second network element;

[0174] Energy efficiency information of the second network element;

[0175] indication information indicating that the energy consumption information of the second network element is greater than or equal to a third threshold;

[0176] Indication information indicating that the energy efficiency information of the second network element is less than or equal to a fourth threshold.

[0177] Second network element reselection indication;

[0178] Network energy-saving instructions or network energy-saving strategy information;

[0179] The first condition includes: the energy consumption information of the first network element is greater than or equal to a first threshold, or the energy efficiency information of the first network element is less than or equal to a second threshold.

[0180] In some embodiments, when the first network element satisfies the first condition, or the first information includes at least one of indication information indicating that the energy consumption information of the first network element is greater than or equal to a third threshold, indication information indicating that the energy efficiency information of the first network element is less than or equal to a fourth threshold, a second network element reselection indication, a network energy saving indication, and network energy saving strategy information, the above-mentioned step S202 may include the above-mentioned step E1.

[0181] In some embodiments, the first network element may be a first UPF. Exemplarily, when the first UPF satisfies the first condition, or when the first UPF receives at least one of indication information indicating that energy consumption information of the first UPF is greater than or equal to a third threshold, indication information indicating that energy efficiency information of the first UPF is less than or equal to a fourth threshold, a second network element reselection indication, a network energy saving indication, and network energy saving policy information, the first UPF sends the first information to the SMF to instruct the SMF to select or reselect a UPF with lower energy consumption or higher energy efficiency.

[0182] In some embodiments, the SMF may receive first information from a first network element.

[0183] In some embodiments, the above-mentioned first information may include energy consumption-related information of the first UPF, at least one of a second network element reselection indication, a network energy-saving indication, and network energy-saving strategy information.

[0184] In some embodiments, the above-mentioned second network element reselection indication, network energy saving indication and network energy saving policy information can be used to indicate the reselection of UPF.

[0185] In some embodiments of the present application, the above-mentioned step S203, step S204 or step S205 can be implemented through the following steps S206 and S207.

[0186] Step S206: The first network element sends a network element discovery request to the fourth network element.

[0187] The network element discovery request carries the third network element type information and the first indication.

[0188] Step S207: The first network element receives a network element discovery response from the fourth network element.

[0189] The network element discovery response includes an identifier of at least one third network element that meets the third condition.

[0190] Among them, the above-mentioned third condition includes: the energy consumption information of the network element is less than or equal to the fifth threshold, or the energy efficiency information of the network element is greater than or equal to the sixth threshold, or the network element uses green energy, and the above-mentioned first indication is used to instruct the fourth network element to return to the network element that meets the third condition or the network element that uses green energy.

[0191] For example, taking the first network element as AMF and the fourth network element as NRF as an example, when the AMF has high energy consumption or the SMF has high energy consumption, it can send a network element discovery request to the NRF to query the NRF for an AMF or SMF with lower energy consumption or higher energy efficiency.

[0192] For example, taking the first network element as SMF and the fourth network element as OAM, SMF can send a network element discovery request to OAM when its own energy consumption is high or UPF energy consumption is high, so as to query OAM for SMF or UPF with lower energy consumption or higher energy efficiency.

[0193] For example, taking the first network element as UPF and the fourth network element as OAM as an example, UPF can send a network element discovery request to OAM when its own energy consumption is high, so as to query OAM for UPFs with lower energy consumption or higher energy efficiency.

[0194] In some embodiments of the present application, the network element discovery request further includes at least one of the following:

[0195] A network element identifier list, where the network element identifier list includes a network element identifier of at least one network element;

[0196] The third condition, the above third condition is used for the fourth network element to return the network element that meets the third condition.

[0197] In some embodiments, the first network element first queries the NRF for a first network element or a network element identifier list, and then sends the first network element or the network element identifier list to the OAM / EENF / NWDAF to obtain a third network element with low energy consumption and high energy efficiency.

[0198] In some embodiments of the present application, the above step S201 can be implemented by the following step S201a.

[0199] Step S201a: The first network element receives first information from the fourth network element.

[0200] The fourth network element is at least one of OAM, EENF, NWDAF, SMF, UPF and PCF.

[0201] In some embodiments of the present application, the above step S201 can be implemented by the following steps S201b and S201c.

[0202] Step S201b: The first network element sends a first request message to the fourth network element.

[0203] The first request message is used to obtain the first information.

[0204] Step S201c: The first network element receives first information from the fourth network element.

[0205] In some embodiments of the present application, before the above step S201a, the energy efficiency or energy consumption optimization method provided in the embodiment of the present application may include the following step S208:

[0206] Step S208: The first network element subscribes to the fourth network element for the first event.

[0207] The first event includes:

[0208] Information sending conditions;

[0209] The first event is used to trigger the fourth network element to send the first information to the first network element when the information sending condition is met.

[0210] In some embodiments of the present application, the above-mentioned information sending condition includes at least one of the following:

[0211] The first network element satisfies the first condition;

[0212] The second network element satisfies the second condition;

[0213] The information is sent at a specific time period;

[0214] The first condition includes: the energy consumption information of the first network element is greater than or equal to a first threshold, or the energy efficiency information of the first network element is less than or equal to a second threshold;

[0215] The second condition includes: the energy consumption information of the second network element is greater than or equal to a third threshold, or the energy efficiency information of the second network element is less than or equal to a fourth threshold.

[0216] In some embodiments, the first network element may send a subscription message to the fourth network element, where the subscription message is used to subscribe the fourth network element to the first event. Exemplarily, the subscription message may carry the ID of the first network element or the ID of the second network element, and may also include an energy consumption threshold or an energy efficiency threshold, where the energy consumption threshold indicates that the energy consumption exceeds a certain value, or that the energy efficiency is lower than a certain value.

[0217] In some embodiments, when the first network element contracts a first event with the fourth network element, the fourth network element performs event monitoring of the first information, and if the energy consumption threshold is met, indicating that the energy consumption value exceeds a certain value, or the energy efficiency is lower than a certain energy efficiency value, the first information is sent to the first network element.

[0218] The above process is exemplarily described below with reference to the accompanying drawings.

[0219] Exemplarily, taking the fourth network element as OAM, EENF, NWDAF or PCF, as shown in Figure 4, the first network element (i.e., the first NF) sends a signing message to the OAM, EENF, NWDAF or PCF, and the signing message carries the ID of the first network element or the ID of the second network element. Exemplarily, the signing message may also include an energy consumption threshold or an energy efficiency threshold, and the energy consumption threshold indicates that a certain energy consumption value is exceeded, or the energy efficiency is lower than a certain energy efficiency value. The OAM, EENF, NWDAF or PCF sends a reply signing response to the first network element and performs event monitoring of the first information. If the energy consumption threshold is met to indicate that a certain energy consumption value is exceeded, or the energy efficiency is lower than a certain energy efficiency value, the fourth network element sends the first information to the first network element.

[0220] In some embodiments, when the first condition is met, that is, when the energy consumption information of the first network element is greater than or equal to the first threshold, or when the energy efficiency information of the first network element is less than or equal to the second threshold, the fourth network element sends first information to the first network element. The first information may include at least one of the following:

[0221] Energy consumption information of the first network element;

[0222] Energy efficiency information of the first network element;

[0223] Indication information indicating that energy consumption information of the first network element is greater than or equal to a first threshold;

[0224] indication information indicating that the energy efficiency information of the first network element is less than or equal to a second threshold;

[0225] Network element reselection indication;

[0226] Network energy saving indicator.

[0227] In some embodiments, when the second condition is met, that is, when the energy consumption information of the second network element is greater than or equal to the third threshold, or when the energy efficiency information of the second network element is less than or equal to the fourth threshold, the fourth network element sends first information to the first network element. The first information may include at least one of the following:

[0228] Energy consumption information of the second network element;

[0229] Energy efficiency information of the second network element;

[0230] Indication information indicating that energy consumption information of the second network element is greater than or equal to a first threshold;

[0231] indication information indicating that the energy efficiency information of the second network element is less than or equal to a second threshold;

[0232] Network element reselection indication;

[0233] Network energy saving indicator.

[0234] In some embodiments, the fourth network element sends the first information to the first network element when a specific time period is met.

[0235] In some embodiments, when the first network element meets the first condition or the second network element meets the second condition, the fourth network element sends first information to the first network element. The first information may include at least one of a network element reselection indication and a network element energy saving indication.

[0236] FIG3 is a schematic diagram of an energy efficiency or energy consumption optimization method provided in an embodiment of the present application. As shown in FIG3 , the energy efficiency or energy consumption optimization method may include the following steps S301:

[0237] Step S301: The fourth network element sends first information to the first network element.

[0246] indication information indicating that the energy consumption information of the second network element is greater than or equal to a third threshold;

[0247] Indication information indicating that the energy efficiency information of the second network element is less than or equal to a fourth threshold.

[0248] In some embodiments of the present application, the above step S301 may include at least one of the following steps S301a to S301c:

[0249] Step S301a: The fourth network element sends the first information to the first network element based on the implementation or pre-configured policy information;

[0250] Step S301b: Upon receiving the first request message from the first network element, the fourth network element sends the first information to the first network element, where the first request message is used to obtain the first information.

[0251] Step S301c: The fourth network element sends the first information to the first network element when the first network element subscribes to the fourth network element for the first event and the fourth network element meets the information sending conditions.

[0252] In some embodiments of the present application, the information sending condition includes at least one of the following:

[0253] The first network element satisfies the first condition;

[0254] The second network element satisfies the second condition;

[0255] The information is sent at a specific time period;

[0256] The first condition includes: the energy consumption information of the first network element is greater than or equal to a first threshold, or the energy efficiency information of the first network element is less than or equal to a second threshold;

[0257] The second condition includes: the energy consumption information of the second network element is greater than or equal to a third threshold, or the energy efficiency information of the second network element is less than or equal to a fourth threshold.

[0258] In some embodiments of the present application, the energy efficiency or energy consumption optimization method provided in the embodiments of the present application may include the following steps S302 and S303:

[0259] Step S302: The fourth network element receives a network element discovery request from the first network element.

[0260] The network element discovery request carries the third network element type information and the first indication.

[0261] Step S303: The fourth network element sends a network element discovery response to the first network element.

[0262] The network element discovery response includes an identifier of at least one third network element that meets the third condition;

[0263] Among them, the third condition includes: the energy consumption information of the network element is less than or equal to the fifth threshold, or the energy efficiency information of the network element is greater than or equal to the sixth threshold, or the network element uses green energy, and the first indication is used to instruct the fourth network element to return to the network element that meets the third condition or the network element that uses green energy.

[0264] In some embodiments of the present application, the network element discovery request further includes at least one of the following:

[0265] A network element identification list, wherein the network element identification list includes a network element identification of at least one network element;

[0266] The third condition.

[0267] It should be noted that the explanation of this embodiment can be found in the relevant description of the above embodiment, which will not be repeated here.

[0268] The energy efficiency or energy consumption optimization method provided in the embodiments of the present application is exemplified below through specific examples.

[0269] Example 1: Taking the first network element as the first AMF and the third network element as the second AMF as an example, the process of the first AMF performing AMF selection or reselection (i.e., registration-with AMF re-allocation) based on energy consumption, energy efficiency, reselection indication, energy saving indication and other information is exemplified.

[0270] For example, as shown in FIG5 , the above energy efficiency or energy consumption optimization method may include the following steps 11 to 14:

[0271] Step 11: The first AMF obtains the first information.

[0272] It should be noted that, for the explanation of the first information and the process of obtaining the first information, reference can be made to the relevant description of the above embodiment, which will not be repeated here.

[0273] Step 12: The RAN forwards the UE's registration request message to the first AMF.

[0274] Exemplarily, the registration request message may be carried by an initial UE message or an uplink NAS transport message (ie, initial UE message or Uplink NAS Transport message).

[0275] Step 13: The first AMF obtains the second AMF.

[0276] For example, when the first AMF obtains that its own energy consumption exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value or the energy efficiency is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF / PCF, or an energy efficiency optimization notification, or an indication to reselect a network device, the first AMF obtains the second AMF and performs AMF reselection or redirection during the registration process.

[0277] It should be noted that the description of the process of the first AMF obtaining the second AMF can be found in the relevant description of the above embodiment and will not be repeated here.

[0278] For example, the above step 13 may be followed by the following step 14a, or the above step 13 may be followed by the following step 14b and step 14c:

[0279] Step 14a: The first AMF sends a registration request message to the second AMF.

[0280] Exemplarily, the first AMF directly redirects the registration request to the second AMF, that is, the first AMF sends a Namf_communication_N1MessageNotify message carrying the registration request to the selected second AMF.

[0281] Namf_communication_N1MessageNotify may contain a redirection reason value of energy consumption or energy efficiency, such as energy saving, energy efficiency and energy consumption optimization.

[0282] Step 14b: The first AMF sends a registration request message to the RAN.

[0283] Exemplarily, the first AMF redirects the registration request to the second AMF through the RAN, including the first AMF sending a forwarding NAS message (i.e., reroute NAS message), which carries the UE's registration request and the second AMF identifier selected above, and may also include a redirected energy consumption or energy efficiency reason value, such as energy saving, energy efficiency and energy consumption optimization.

[0284] Step 14c: The RAN sends a registration request message to the second AMF.

[0285] Exemplarily, the registration request message may be carried by UE initial information (ie, Initial UE message).

[0286] Example 2: In combination with the above-mentioned Example 1, taking the first network element as the first AMF as an example, the process of the first AMF registering the UE based on information such as energy consumption, energy efficiency, reselection indication, and energy saving indication is exemplified.

[0287] For example, as shown in FIG6 , in combination with the above embodiment 1, the above energy efficiency or energy consumption optimization method may include the following steps 21 to 23:

[0288] Step 21: The first AMF obtains the first information.

[0289] Step 22: The first AMF sends a deregistration request message (i.e., Deregistration request) to the UE.

[0290] For example, the first AMF initiates the deregistration process when it finds that its own energy consumption exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value or the energy efficiency is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF, or an energy efficiency optimization notification, or an indication to reselect a network device.

[0291] Exemplarily, when the UE is in a registered state, the first AMF sends a deregistration request message to the UE.

[0292] Exemplarily, the deregistration request message carries a deregistration reason value of network energy saving, or high energy consumption / low energy efficiency of network equipment. Exemplarily, the deregistration request message may carry a re-registration indication.

[0293] Exemplarily, the deregistration request message may also carry an energy-saving backoff timer value.

[0294] Step 23: The UE sends a registration request message (i.e., registration request) to the first AMF.

[0295] Exemplarily, if the deregistration request message carries a re-registration indication, the UE initiates re-registration and sends a registration request.

[0296] Exemplarily, after receiving the registration request message from the UE, the first AMF may perform the operations of the above-mentioned embodiment 1.

[0297] Example 3: In combination with the above-mentioned Example 2, taking the first network element as the first AMF as an example, the process of the first AMF rejecting the UE's registration request is exemplified.

[0298] For example, as shown in FIG7 , the above energy efficiency or energy consumption optimization method may include the following steps 31 to 33:

[0299] Step 31: The first AMF obtains the first information.

[0300] Step 32: The UE sends a registration request message to the first AMF.

[0301] Step 33: The first AMF sends a registration rejection message to the UE.

[0302] Exemplarily, the first AMF refuses to perform UE registration when it determines that its own energy consumption is high or its energy efficiency is low.

[0303] Exemplarily, the registration rejection message carries a reason for registration rejection, such as energy saving or energy efficiency optimization.

[0304] Example 4: Taking the first network element as the first SMF (SMF1) and the third network element as the second SMF as an example, the process of first releasing the PDU session and then reestablishing the PDU session, performing SMF reselection, and SMF instructing AMF to select an SMF with low energy consumption and high energy efficiency is exemplified.

[0305] For example, as shown in FIG8 , the above energy efficiency or energy consumption optimization method may include the following steps 41 to 47:

[0306] Step 41: The first SMF obtains first information.

[0307] Step 42: The first SMF sends a network element reselection indication (i.e., a second network element reselection indication) to the AMF.

[0308] Exemplarily, the network element reselection indication may be carried by Nsmf_PDUSession_SMContextStatusNotify, and the network element reselection indication may carry an SMF reselection indication or an energy saving or high energy consumption or low energy efficiency indication.

[0309] For example, when the UE has established a PDU session, SMF1 obtains that its own energy consumption exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value, or the energy efficiency (such as the amount of data transmitted with a specific energy consumption per unit time) is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF / PCF, or an energy efficiency optimization notification, or an indication to reselect a network device, and then sends a network element reselection indication to AMF to initiate an SMF reselection operation.

[0310] Step 43: AMF sends a response message to the first SMF.

[0311] Exemplarily, the response message may be carried by Nsmf_PDUSession_SmcontextstatusNotify Response.

[0312] Step 44: The first SMF sends a PDU session release command to the UE, carrying a reestablishment indication and a release reason value of energy saving, high energy consumption, or low energy efficiency.

[0313] Step 45: The UE sends a PDU session establishment request (i.e., PDU session establishment reques) to the AMF.

[0314] Exemplarily, the UE initiates a PDU session establishment request according to the reestablishment indication.

[0315] Step 46: The AMF obtains the second SMF.

[0316] Exemplarily, the AMF receives the PDU session establishment request of the UE and selects an SMF different from SMF1 (i.e., the second SMF) according to the reselection indication or energy saving or high energy consumption or low energy efficiency indication of SMF1.

[0317] Step 47: AMF sends a PDU session establishment request to the second SMF.

[0318] Exemplarily, the PDU session establishment request may be carried by Nsmf_PDUSession_CreateSMContext Request.

[0319] For example, AMF may delete the SMF reselection indication or energy saving or high energy consumption or low energy efficiency indication from SMF1 to avoid SMF1 being unable to be selected in subsequent PDU session establishment.

[0320] Exemplarily, after step 47, the UE, AMF and the second SMF perform a PDU session establishment process.

[0321] Example 5: Taking the first network element as SMF, the second network element as the first UPF, and the third network element as the second UPF as an example, the process of reselecting UPF by first releasing the PDU session and then reestablishing the PDU session is exemplified.

[0322] For example, as shown in FIG9 , the above energy efficiency or energy consumption optimization method may include the following steps 51 to 55:

[0323] Step 51: The SMF obtains first information.

[0324] Step 52: The SMF sends a PDU release request message (ie, PDU session release command) to the UE.

[0325] Exemplarily, the PDU session release command may carry a reestablishment indication and a release reason value of energy saving, high energy consumption, or low energy efficiency.

[0326] For example, when the UE has established a PDU session, the SMF obtains that the energy consumption of the first UPF (i.e., UPF1) exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value, or the energy efficiency (such as the amount of data transmitted with a specific energy consumption per unit time) is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF, or an energy efficiency optimization notification, or an indication to reselect UPF, and the SMF sends a PDU release request message to perform UPF reselection.

[0327] Step 53: The UE sends a PDU session establishment request (i.e., PDU session establishment request) to the AMF.

[0328] Exemplarily, the UE may initiate a PDU session establishment request according to the reestablishment indication.

[0329] Step 54: AMF sends a PDU session establishment request to SMF.

[0330] Exemplarily, the above-mentioned PDU session establishment request can be carried by Nsmf_PDUSession_CreateSMContext Request.

[0331] Step 55: The SMF obtains the second UPF.

[0332] Exemplarily, the SMF receives the Nsmf_PDUSession_CreateSMContext Request from the AMF, and the SMF selects a second UPF with low energy consumption / high energy efficiency (ie, UPF2 which is different from UPF1).

[0333] Exemplarily, the SMF may delete the acquired energy consumption related information of the UPF.

[0334] Exemplarily, after step 54, the UE, AMF, SMF and UPF2 perform a PDU session establishment process. Exemplarily, the SMF establishes an N4 session with the second UPF.

[0335] Example 6: Taking the first network element as the first SMF (SMF1) and the third network element as the second SMF as an example, the process of reselecting the SMF in the process of establishing and releasing the PDU session is exemplified.

[0336] For example, as shown in FIG10 , the above energy efficiency or energy consumption optimization method may include the following steps 61 to 69:

[0337] Step 61: The first SMF obtains first information.

[0338] Step 62: The first SMF sends an SMF reselection indication (i.e., a second network element reselection indication) to the AMF.

[0339] Exemplarily, the second network element reselection indication may be carried via Namf_Communication_N1N2MessageTransfer.

[0340] Exemplarily, the SMF reselection indication may carry a reason value for energy saving, high energy consumption, or low energy efficiency of the network device.

[0341] For example, when the UE already has a PDU session established through SMF1 and the first UPF (UPF1), SMF1 obtains that the energy consumption of SMF1 exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value, or the energy efficiency (such as the amount of data transmitted with a specific energy consumption per unit time) is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF, or an energy efficiency optimization notification, or an instruction to reselect SMF and / or UPF, SMF1 executes the operation of first establishing a PDU session and then releasing the PDU session to achieve the replacement of SMF1.

[0342] Step 63: AMF sends a PDU session modification command to the UE.

[0343] Exemplarily, the PDU session modification command carries an indication for reestablishing the PDU session, and may also carry a reason value for reestablishment, such as network energy saving, high energy consumption, or low energy efficiency.

[0344] Step 64: The UE sends a confirmation message to the AMF.

[0345] Exemplarily, the confirmation message may be carried by PDU session modification Command ACK.

[0346] Step 65: The AMF forwards the UE's confirmation message to the first SMF.

[0347] Step 66: The first SMF replies a confirmation message to the AMF.

[0348] Exemplarily, the above confirmation message may be carried by Nsmf_PDUSession_UpdateSMContext Reponse.

[0349] Step 67: The UE sends a PDU session establishment request to the AMF.

[0350] For example, the UE may send a PDU session establishment request with the same DN to the AMF via a PDU session establishemnt request.

[0351] Step 68: The AMF selects a second SMF.

[0352] Exemplarily, the AMF selects the second SMF based on the SMF reselection indication and / or the reason value for energy saving, high energy consumption or low energy efficiency of the network device.

[0353] Step 69: AMF sends the PDU session establishment request to the second SMF (SMF2).

[0354] Exemplarily, the AMF may send the UE's PDU session establishment request to the second SMF via Nsmf_PDUSession_CreateContext Request.

[0355] Exemplarily, after step 69, the UE, AMF and the second SMF continue to perform the subsequent PDU session establishment process.

[0356] Example 7: Taking the first network element as the first SMF (SMF1) or the first UPF (UPF1), the second network element as the first SMF or the first UPF, and the third network element as the second UPF as an example, the process of reselecting UPF in the process of establishing a PDU session and then releasing the PDU session is explained by way of example.

[0357] For example, as shown in FIG11 , the above energy efficiency or energy consumption optimization method may include the following steps 71 to 79:

[0358] Step 71: The first SMF obtains first information.

[0359] Step 72: The first SMF sends a network element reselection indication to the AMF.

[0360] Exemplarily, the above-mentioned network element reselection indication is used to indicate the reselection of SMF or UPF.

[0361] Exemplarily, the above network element reselection indication may be carried by a Namf_Communication_N1N2MessageTransfer message.

[0362] Exemplarily, the message may also carry a reason value for energy saving, high energy consumption, or low energy efficiency of the network device.

[0363] For example, when the UE already has a PDU session established through SMF1 and UPF1, SMF1 obtains that the energy consumption of UPF1 exceeds a predetermined value, or the energy consumption per unit time exceeds a predetermined value, or the energy efficiency (such as the amount of data transmitted with a specific energy consumption per unit time) is lower than a predetermined value, or receives an energy-saving notification from OAM / EENF / NWDAF, or an energy efficiency optimization notification, or an instruction to reselect SMF and / or UPF, SMF1 executes the operation of first establishing a PDU session and then releasing the PDU session to achieve the replacement of UPF1.

[0364] Step 73: AMF sends a PDU session reestablishment request to the UE.

[0365] Exemplarily, the PDU session reestablishment request may be carried by a PDU session modification command.

[0366] Exemplarily, the PDU session modification command may further carry a reconstruction reason value of network energy saving, high energy consumption, or low energy efficiency.

[0367] Step 74: After receiving the message, the UE replies with a confirmation message.

[0368] Exemplarily, the confirmation message may be carried by PDU session modification Command ACK.

[0369] Step 75: The AMF forwards the UE's confirmation message to the first SMF.

[0370] Exemplarily, the confirmation message may be carried by Nsmf_PDUSession_UpdateSMContext request.

[0371] Step 76: The first SMF replies a confirmation message to the AMF.

[0372] Exemplarily, the above confirmation message may be carried by Nsmf_PDUSession_UpdateSMContext Reponse.

[0373] Step 77: The UE sends a PDU session establishment request to the AMF.

[0374] Step 78: AMF sends the UE's PDU session establishment request to the first SMF.

[0375] Step 79: The first SMF obtains the second UPF.

[0376] Exemplarily, SMF1 selects a UPF (UPF2) that is different from UPF1.

[0377] Exemplarily, after the above step 79, SMF1 and UPF2 continue to perform the subsequent PDU session establishment process.

[0378] Embodiment 8: The first network element queries the fourth network element (NRF / OAM / EENF / NWDAF) and selects a third network element with low energy consumption and high energy efficiency.

[0379] In some implementations, the first network element queries the fourth network element for a third network element with low energy consumption or high energy efficiency. For example, taking the first network element as a first NF and the fourth network element as an NFR, OAM, EENF, or NWDAF as an example, as shown in FIG12 , the above energy efficiency or energy consumption optimization method may include at least one of the following steps 81a and 81b:

[0380] Step 81a: The first network element sends a network element discovery request to the NRF, where the network element discovery request carries at least one of the first network element type, the second network element type, low energy consumption, energy saving, and high energy efficiency indications.

[0381] Step 81b: The first network element sends a network element discovery request to at least one of the OAM, EENF, and NWDAF.

[0382] Exemplarily, the above-mentioned first network element can be AMF, SMF or UPF, etc.

[0383] Exemplarily, the network element discovery request is used to query NRF / OAM / EENF / NWDAF for a first NF or a second NF with low energy consumption and high energy efficiency. The network element discovery request may carry the type of the first NF or the second NF and an energy saving / optimization energy efficiency indication.

[0384] Exemplarily, the network element discovery request may be carried by Nnrf_NFDiscovery_request, and the Nnrf_NFDiscovery_request may also carry at least one of the first network element type, the second network element type, a low energy consumption indication, an energy saving indication, and a high energy efficiency indication.

[0385] Optionally, after the above step 81a, the following step 82a may be included, and / or after the above step 81b, the following step 82b may be included:

[0386] Step 82a: The NRF sends a network element discovery response to the first network element. The network element discovery response carries the third network element or the ID of the third network element.

[0387] Exemplarily, the network element discovery response may be carried by Nnrf_NFDiscovery_Response.

[0388] Step 82b: OAM / EENF / NWDAF sends a network element discovery response to the first network element.

[0389] Exemplarily, the network element discovery response includes one or more third network elements with low energy consumption and high energy efficiency, or the ID of the third network element.

[0390] Exemplarily, if multiple third network elements or IDs of third network elements are returned, the first network element selects one network element therefrom based on implementation.

[0391] In some implementations, the first network element queries the NFR for a list of candidate network elements, and then obtains a third network element with low energy consumption or high energy efficiency from the OAM / EENF / NWDAF. For example, the above energy efficiency or energy consumption optimization method may include the following steps 83 to 86:

[0392] Step 83: The first network element sends a network element discovery request to the NRF. The network element discovery request carries at least one of the type of the first network element, the type of the second network element, a low energy consumption indication, an energy saving indication, and a high energy efficiency indication.

[0393] Step 84: The NRF sends the candidate network element list to the first network element.

[0394] Exemplarily, the candidate network element list may include network element identifiers of network elements of the same type as the first network element, or may include network element identifiers of network elements of the same type as the second network element.

[0395] Exemplarily, the candidate network element list may be carried in Nnrf_NFDiscovery_Response.

[0396] Step 85: The first network element sends a network element discovery selection request to the OAM / EENF / NWDAF. The network element discovery request carries at least one of a candidate network element list, a first network element type, a second network element type, a low energy consumption indication, a energy saving indication, and a high energy efficiency indication.

[0397] Step 86: OAM / EENF / NWDAF returns the network element identifiers of one or more network elements with low energy consumption and high energy efficiency to the first network element.

[0398] Exemplarily, if multiple network element identifiers are returned, the first network element selects one based on implementation.
