[0050] Figure 2 It is a schematic diagram of the energy efficiency or energy consumption optimization method provided by the embodiments of the present application. As Figure 2 shown, the energy efficiency or energy consumption optimization method may include the following steps S201 and step S202:

[0051] Step S201: The first network element obtains first information.

[0052] Among them, the above-mentioned first information includes energy consumption-related information of the network element.

[0053] In some embodiments of the present application, the energy consumption-related information of the network element includes at least one of the following:

[0054] Energy consumption information of the first network element;

[0055] Energy efficiency information of the first network element;

The energy consumption and energy efficiency of a network element can be calculated based on the amount of data transmitted with a specific energy consumption per unit time.

[0063] In some embodiments of the present application, the above-mentioned first network element may be an AMF, an SMF, or a UPF, and the above-mentioned second network element may be an AMF, an SMF, or a UPF.

[0064] In some embodiments of the present application, the above-mentioned first network element and the second network element may be the same network element or different network elements.

[0065] 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.

[0066] It should be noted that the above-mentioned first network element or the second network element may also be other network elements that need to save energy in the communication network, and the embodiments of the present application do not limit this.

[0067] 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 the energy consumption-related information of other network elements different from itself.

[0068] In some embodiments of the present application, the first network element may obtain first information from a fourth network element, and the fourth network element may include at least one of the following: OAM, EENF, NWDAF, SMF, UPF, and PCF.

[0069] In some embodiments of the present application, the above-mentioned first information further includes at least one of the following:

[0070] First network element reselection indication;

[0071] Second network element reselection indication;

[0072] Network energy saving indication or network energy saving policy information.

[0073] In some embodiments, the above first network element reselection indication is used to indicate the selection or reselection of a network element with energy consumption information less than or equal to a first threshold, or the above first network element reselection indication is used to indicate the reselection of a network element with energy efficiency information greater than or equal to a second threshold.

[0075] In some embodiments, the above 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 with energy consumption information less than or equal to a fifth threshold, or to indicate the selection or reselection of a network element with energy efficiency information greater than or equal to a sixth threshold.

[0076] In some embodiments, the above network energy saving policy information is used to perform an energy saving operation.

[0077] In some embodiments of the present application, the above first network element reselection indication may include the reason for reselection, and the reason for reselection may be network energy saving or energy efficiency optimization; the above second network element reselection indication may include the reason for reselection, and the reason for reselection may be network energy saving or energy efficiency optimization.

[0078] Step S202: The first network element performs a first operation related to energy saving according to the first information.

[0079] 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 an indication that the energy consumption information of the first network element is greater than or equal to the first threshold, an indication that the energy efficiency information of the first network element is less than or equal to the second threshold, an indication that the energy consumption information of the second network element is greater than or equal to the third threshold, and an indication that the energy efficiency information of the second network element is less than or equal to the fourth threshold.

[0080] 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 may 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.

[0081] It can be understood that the above network element may be at least one of the first network element and the second network element.

[0082] In some embodiments of the present application, when the first network element obtains 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, it performs a first energy-saving related operation.

[0083] For the energy efficiency or energy consumption optimization method provided by the embodiments of the present application, the first network element obtains first information, and the first information includes energy consumption related information of the network element. The first network element performs a first energy-saving related operation according to the first information. Through this method, the first network element can perform a first energy-saving related operation according to the energy consumption related information of the network element, realize the optimization of the energy efficiency or energy consumption of the network, and avoid resource waste caused by large energy consumption when the network element participates in communication under the condition of high energy consumption or low energy efficiency, thereby saving network resources.

[0084] In some embodiments of the present application, the above step S202 can be implemented through the following step S202a:

[0085] 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 energy-saving related operation.

[0086] Wherein, the above 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; the above 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.

[0087] In some embodiments, when the first information includes the energy consumption related information of the first network element, the first network element can determine whether the first network element meets the first condition according to the energy consumption related information of the first network element; or, when the first information includes the energy consumption related information of the second network element, the first network element can determine whether the second network element meets the second condition according to the energy consumption related information of the second network element.

[0088] Exemplarily, taking the first network element as the AMF and the second network element as the AMF as an example, the AMF performs a first energy-saving related operation when its own energy consumption exceeds a predetermined value or its energy efficiency is lower than a predetermined value.

[0089] Exemplarily, taking the first network element as the AMF and the second network element as the SMF as an example, the AMF performs a first energy-saving related operation when it obtains that the energy consumption of the SMF exceeds a predetermined value or its energy efficiency is lower than a predetermined value.

[0090] Exemplarily, taking the first network element as the SMF and the second network element as the SMF as an example, the SMF performs a first energy-saving related operation when it obtains that its own energy consumption exceeds a predetermined value or its energy efficiency is lower than a predetermined value.

[0091] Exemplarily, taking the first network element as the SMF and the second network element as the 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, it performs a first operation related to energy saving.

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

[0093] In the embodiments of the present application, the first network element may perform a first operation related to energy saving when it obtains that its own energy consumption exceeds a predetermined value or the energy efficiency is lower than a predetermined value, or when it obtains that the energy consumption of the second network element exceeds a predetermined value or the energy efficiency is lower than a predetermined value, so as to optimize the energy consumption or energy efficiency of the network element, thereby saving network resources.

[0094] In some embodiments of the present application, the first network element is the AMF, and the above step S202 may include at least one of the following steps A1 and step A2:

[0095] Step A1: When the first network element receives a registration request message from a User Equipment (UE), it sends the registration request message to a third network element.

[0096] Wherein, the network element type of the above third network element is the same as that of the first network element.

[0097] Step A2: The first network element sends a deregistration request message to the UE.

[0098] In some embodiments, when the first network element is the AMF and the first network element meets the first condition, or the first information includes at least one of an indication information indicating that the energy consumption information of the first network element is greater than or equal to a first threshold, an 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 policy information, the above step S202 may include at least one of the above steps A1 and step A2.

[0099] Wherein, 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.

[0100] In some possible implementation manners, 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 the third network element, so that the UE can register on the third network element.

[0101] In some embodiments, the above-mentioned third network element meets the third condition, which includes that the energy consumption information of the third network element is less than or equal to the fifth threshold, or at least one of the energy efficiency information of the third network element is greater than or equal to the sixth threshold.

[0102] Exemplarily, 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 register the UE with an AMF that has lower energy consumption or higher energy efficiency selected or reselected for the UE.

[0103] In some possible implementation manners, when the first network element receives a registration request from the UE and the first network element 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 the first threshold, indication information indicating that the energy efficiency information of the first network element is less than or equal to the second threshold, a network energy saving indication, and network energy saving policy information, the first network element may forward the registration request to the third network element so that the UE can register on the third network element.

[0104] After the above step A1, the third network element may receive a registration request message from the first network element and execute the registration process.

[0105] In some possible implementation manners, when the first network element meets the first condition, it sends a deregistration request message to the UE to deregister the UE, thereby saving network resources.

[0106] It can be understood that the above deregistration request message may be used to request deregistration of the UE.

[0107] In some possible implementation manners, 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.

[0108] Exemplarily, taking the first network element as the first AMF as an example, when the first AMF receives at least one of a first network element reselection indication, a network energy saving indication, and network energy saving policy information, if the first AMF meets the first condition, it sends a deregistration request message to the UE to deregister the UE, avoiding the first AMF participating in communication when the energy consumption is high or the energy efficiency is low, thereby saving network resources.

[0109] In some embodiments of the present application, the above deregistration request message includes at least one of the following:

[0110] Indication information indicating the energy consumption or energy efficiency reason for performing deregistration;

[0111] Indication information for instructing re-registration.

[0112] In some embodiments, the above energy consumption or energy efficiency reasons may be network energy saving or energy efficiency optimization, etc.

[0113] In some embodiments, when the indication information for instructing re-registration is included in the deregistration request message, the UE may initiate re-registration, that is, re-send a registration request message to the first network element. The first network element may 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.

[0114] In the embodiments of the present application, when the first network element has high energy consumption or low energy efficiency, by reselecting network devices with low energy consumption and high energy efficiency, network energy saving and energy efficiency improvement are achieved.

[0115] In some embodiments of the present application, before the first network element sends a registration request message to the third network element in step A1, the energy efficiency or energy consumption optimization method provided by the embodiments of the present application may include the following step S203:

[0116] Step S203: The first network element obtains the third network element.

[0117] In some embodiments, the first network element may obtain the third network element from the fourth network element.

[0118] It should be noted that the explanation of the fourth network element can be referred to the above text and will not be elaborated here.

[0119] Exemplarily, taking the first network element as the AMF and the fourth network element as the OAM as an example, the AMF may query the target AMF (i.e., the third network element) that meets the third condition (i.e., low energy consumption and high energy efficiency) from the OAM; or, the AMF first queries the AMF list from the OAM, the AMF list includes the identifiers of one or more AMFs, and then sends the AMF list to the OAM to obtain a target AMF that meets the third condition from the AMF list by the OAM.

[0120] In some embodiments of the present application, when the first network element is the SMF, the above step S202 may include at least one of the following steps B1 to B3:

[0121] Step B1: The first network element sends the first information to the AMF.

[0122] Among them, the first information includes a second network element reselection indication, and the second network element reselection indication is used to indicate reselection of the SMF.

[0123] Step B2: The first network element sends a PDU session release command to the UE.

[0124] Step B3: The first network element sends a PDU session modification command to the UE.

[0125] In some embodiments, when the first network element meets 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 policy information, the above step S202 may include at least one of the above steps B1 to B3.

[0126] Wherein, 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.

[0127] In some possible implementation manners, when the SMF obtains that its own energy consumption exceeds a certain predetermined value, or the energy consumption per unit time exceeds a certain predetermined value or the energy efficiency is lower than a certain predetermined value, or receives an energy saving notification, an energy efficiency optimization notification, or a network device reselection indication from the OAM / EENF / NWDAF, the SMF sends a network element reselection indication to the AMF to indicate the execution of SMF reselection. The AMF may receive the network element reselection indication sent by the SMF and reselect the SMF according to the network element reselection indication, so as to select an SMF with lower energy consumption or higher energy efficiency for communication.

[0128] In some possible implementation manners, when the SMF obtains that its own energy consumption exceeds a certain predetermined value, or the energy consumption per unit time exceeds a certain predetermined value or the energy efficiency is lower than a certain predetermined value, or receives an energy saving notification, an energy efficiency optimization notification, or a network device reselection indication from the OAM / EENF / NWDAF, the SMF sends a PDU session release command to the UE to indicate the release of the PDU session between the SMF and the UE, so as to avoid excessive resource consumption caused by the SMF continuing to participate in communication.

[0129] In some possible implementation manners, when the SMF obtains that its own energy consumption exceeds a certain predetermined value, or the energy consumption per unit time exceeds a certain predetermined value or the energy efficiency is lower than a certain predetermined value, or receives an energy saving notification, an energy efficiency optimization notification, or a network device reselection indication from the OAM / EENF / NWDAF, the SMF sends a PDU session modification command to the UE to indicate the reconstruction of the PDU session between the UE and the SMF, so as to avoid excessive resource consumption caused by the SMF continuing to participate in communication.

[0130] It can be understood that the PDU session modification command may be a PDU session reconstruction command and may be used to indicate the reconstruction of the PDU session.

[0131] In some embodiments of the present application, the above PDU session release command carries at least one of indication information indicating re - establishment of a PDU session and indication information indicating the energy consumption or energy efficiency reason for the PDU session release; and / or, the above PDU session modification command carries at least one of indication information indicating re - establishment of a PDU session and indication information indicating the energy consumption or energy efficiency reason for the PDU session modification.

[0132] In some embodiments of the present application, the above second network element reselection indication may include at least one of indication information indicating the energy consumption or energy efficiency reason for reselection.

[0133] In some embodiments, when the indication information indicating re - establishment of a PDU session is carried in the PDU session release command, the UE may initiate a PDU session establishment request again according to the indication information.

[0134] Exemplarily, the UE may send a PDU session establishment request to the AMF. When the AMF receives the PDU session establishment request from the UE, according to the second network element reselection indication, it selects an SMF with lower energy consumption or an SMF with higher energy efficiency to establish a PDU session.

[0135] In some embodiments of the present application, the first network element is the AMF, and the above step S202 may include the following step C1:

[0136] Step C1: When the first network element receives a PDU session establishment request from the UE, it sends the PDU session establishment request to the third network element.

[0137] Wherein, the network element type of the third network element is the same as that of the second network element.

[0138] In some embodiments, when the second network element meets 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 step S202 may include the above step C1.

[0139] Wherein, the above 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, and the above first network element reselection indication is used to indicate reselection of the SMF.

[0140] In some embodiments, the second network element may be the first SMF, and the second network element may be the second SMF. Exemplarily, when the AMF receives the PDU session establishment request from the UE and the first SMF meets the second condition, it sends a PUU session establishment request to the second SMF to establish a PDU session with the second SMF.

[0141] In some embodiments, the second network element may be the first SMF, and the second network element may be the second SMF. Exemplarily, 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 to establish a PDU session with the second SMF.

[0142] In some embodiments, the second network element may be the first SMF, and the second network element may be the second SMF. Exemplarily, 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 a third threshold, and indication information indicating that the energy efficiency information of the first SMF is less than or equal to a fourth threshold, the AMF sends the PUU session establishment request to the second SMF to establish a PDU session with the second SMF. Thus, when the energy consumption of the first SMF currently participating in communication is high or the energy efficiency is low, the AMF can select the 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 as to be able to select an SMF with lower energy consumption or higher energy efficiency to participate in communication, thereby saving network resources.

[0143] In some embodiments of the present application, before the first network element sends a PDU session establishment request to the third network element in step C1, the energy efficiency or energy consumption optimization method provided by the embodiments of the present application may include the following step S204:

[0144] Step S204: The first network element obtains the third network element.

[0145] In some embodiments, the first network element may obtain the third network element and establish a PDU session with the third network element when receiving a PDU session establishment request from the UE.

[0146] In some embodiments, the first network element may obtain the third network element from the fourth network element. Exemplarily, taking the first network element as the AMF, the AMF may obtain the third network element from the fourth network element.

[0147] 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 D1 to D3:

[0148] Step D1: The first network element sends a PDU session release command to the UE.

[0149] Step D2: The first network element sends a PDU session modification command to the UE.

[0150] Step D3: When the first network element receives a PDU session establishment request from the UE, it establishes a PDU session with the third network element.

[0151] Wherein, the network element type of the third network element is the same as that of the second network element.

[0152] In some embodiments, when the second network element meets 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 step S202 may include at least one of the following steps D1 to D3.

[0153] Wherein, 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, and the second network element reselection indication is used to indicate reselection of the UPF.

[0154] In some embodiments, when the first network element receives a PDU session establishment request from the UE, it may establish an N4 session with the third network element.

[0155] In some embodiments, the above PDU session release command is used to indicate the release of the PDU session with the second network element.

[0156] In some embodiments, the above PDU session modification command is used to indicate modification or reconstruction of the PDU session.

[0157] In some embodiments, the second network element may be the first UPF, and the second network element may be the second UPF. Exemplarily, when the first UPF meets 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, so as to prevent the first UPF from continuing to participate in communication when the energy consumption is high or the energy efficiency is low; or, when the first UPF meets the second condition, the SMF may send a PDU session modification command to the UE to reconstruct the PDU session between the UE and the UPF, so as to prevent the first UPF from continuing to participate in communication when the energy consumption is high or the energy efficiency is low, thereby saving resources.

[0158] In some embodiments, the second network element may be the first UPF, and the second network element may be the second UPF. Exemplarily, when the SMF receives a PDU session establishment request from the UE and the first UPF meets the second condition, it sends a PUU session establishment request to the second UPF to establish an N4 session with the second UPF.

[0159] In some embodiments, the second network element may be the first UPF, and the above-mentioned second network element may be the second UPF. Exemplarily, when the SMF receives a PDU session establishment request from the UE and the first UPF meets the first condition, the SMF establishes an N4 session with the second UPF. In this way, when the first UPF currently participating in communication has high energy consumption or low energy efficiency, the SMF can select the second UPF with low energy consumption or high energy efficiency and establish an N4 session with the second UPF, so that a UPF with low energy consumption or high energy efficiency can be selected to participate in communication, thereby saving network resources.

[0160] In some embodiments, the second network element may be the first UPF, and the above-mentioned second network element may be the second UPF. Exemplarily, when the SMF receives a PDU session establishment request from the UE, and the SMF receives a reselection indication of the second network element, 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 first UPF currently participating in communication has high energy consumption or low energy efficiency, the SMF can select the second UPF with low energy consumption or high energy efficiency and establish an N4 session with the second UPF, so that a UPF with low energy consumption or high energy efficiency can be selected to participate in communication, thereby saving network resources.

[0161] 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 can be deleted. For example, the SMF can delete the energy consumption-related information of the first UPF obtained, so as to avoid being unable to select the second network element subsequently.

[0162] In some embodiments of the present application, before the first network element and the third network element establish a PDU session in step D3, the energy efficiency or energy consumption optimization method provided by the embodiments of the present application may include the following step S205:

[0163] Step S205: The first network element obtains the third network element.

[0164] In some embodiments, taking the first network element as the SMF as an example, the SMF can obtain the third network element from the fourth network element.

[0165] It should be noted that the explanation of the fourth network element can be found above and will not be elaborated here.

[0166] In some embodiments of the present application, the above PDU session release command carries at least one of indication information indicating re - establishment of the PDU session and indication information indicating the energy consumption or energy efficiency reason for the PDU session release; and / or, the above PDU session modification command carries at least one of indication information indicating re - establishment of the PDU session and indication information indicating the energy consumption or energy efficiency reason for the PDU session modification.

[0167] In some embodiments, when the PDU session release command carries at least one of indication information indicating re - establishment of the PDU session and indication information indicating the energy consumption or energy efficiency reason for the PDU session release, 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.

[0168] In some embodiments of the present application, the first network element is a UPF, and the above step S202 may include the following step E1:

[0169] Step E1: The first network element sends first information to the SMF.

[0170] Wherein, the above first information includes at least one of the following:

[0172] Energy efficiency information of the second network element;

[0173] Indication information indicating that the energy consumption information of the second network element is greater than or equal to a third threshold;

[0180] In some embodiments, the SMF may receive the first information from the first network element.

[0181] In some embodiments, the above-mentioned first information may include at least one of energy consumption related information of the first UPF, a second network element reselection indication, a network energy saving indication, and network energy saving policy information.

[0182] In some embodiments, the above-mentioned second network element reselection indication, network energy saving indication, and network energy saving policy information may be used to indicate the reselection of the UPF.

[0183] In some embodiments of the present application, the above-mentioned step S203, step S204, or step S205 may be implemented by the following step S206 and step S207.

[0189] Exemplarily, taking the first network element as the AMF and the fourth network element as the NRF as an example, when the AMF has high energy consumption by itself or the SMF has high energy consumption, the AMF may send a network element discovery request to the NRF to query for an AMF or SMF with lower energy consumption or higher energy efficiency from the NRF.

[0190] Exemplarily, taking the first network element as the SMF and the fourth network element as the OAM as an example, the SMF may send a network element discovery request to the OAM when its own energy consumption is high or the energy consumption of the UPF is high, so as to query the OAM for an SMF or UPF with lower energy consumption or higher energy efficiency.

[0191] Exemplarily, taking the first network element as the UPF and the fourth network element as the OAM as an example, when the UPF's own energy consumption is high, the UPF may send a network element discovery request to the OAM to query the OAM for a UPF with lower energy consumption or higher energy efficiency.

[0192] In some embodiments of the present application, the above network element discovery request further includes at least one of the following:

[0193] A network element identifier list, which includes the network element identifiers of at least one network element;

[0194] A third condition, and the above third condition is used for the fourth network element to return a network element that meets the third condition.

[0195] In some embodiments, the first network element first queries the NRF for the first network element or the 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.

[0196] In some embodiments of the present application, the above step S201 may be implemented through the following step S201a.

[0198] Wherein, the above fourth network element is at least one of the OAM, EENF, NWDAF, SMF, UPF, and PCF.

[0199] In some embodiments of the present application, the above step S201 may be implemented through the following step S201b and step S201c.

[0200] Step S201b: The first network element sends a first request message to the fourth network element.

[0214] In some embodiments, the first network element may send a subscription message to the fourth network element, and this subscription message is used to subscribe to the first event with the fourth network element. Exemplarily, the ID of the first network element or the ID of the second network element may be carried in this subscription message, and the energy consumption threshold or the energy efficiency threshold may also be included in this subscription message, and this energy consumption threshold indicates exceeding a certain energy consumption value, or the energy efficiency is lower than a certain energy efficiency value.

[0215] In some embodiments, when the first network element subscribes to the first event with the fourth network element, the fourth network element performs event monitoring of the first information. If it meets the condition that the energy consumption threshold indicates exceeding a certain energy consumption value, or the energy efficiency is lower than a certain energy efficiency value, it sends the first information to the first network element.

[0216] The above process is exemplarily described below with reference to the accompanying drawings.

Exemplarily, the subscription message may further 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 the energy efficiency is lower than a certain value. The OAM, EENF, NWDAF, or PCF sends a reply subscription response to the first network element and performs event monitoring of the first information.

[0278] 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. The Namf_communication_N1MessageNotify may contain a redirection cause value for energy consumption or energy efficiency, such as energy saving, energy efficiency and energy consumption optimization.

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

[0280] Exemplarily, the first AMF redirects the registration request to the second AMF through the RAN, including the first AMF sending a forwarded NAS message (i.e., reroute NAS message), which carries the UE's registration request, carries the identifier of the above-selected second AMF, and may also contain a redirection cause value for energy consumption or energy efficiency, such as energy saving, energy efficiency and energy consumption optimization.

[0281] Step 14c: The RAN sends a registration request message to the second AMF.

[0282] Exemplarily, the registration request message can be carried by the UE initial information (i.e., Initial UE message).

[0283] Embodiment 2: Combining the above Embodiment 1, taking the first network element as the first AMF as an example, an exemplary description is given of the process in which the first AMF registers the UE according to information such as energy consumption, energy efficiency, reselection indication, and energy saving indication.

[0284] Exemplarily, as Figure 6 shown, combining the above Embodiment 1, the above energy efficiency or energy consumption optimization method may include the following Steps 21 to 23:

[0285] Step 21: The first AMF obtains the first information.

[0286] Step 22: The first AMF sends a deregistration request message (i.e., Deregistration request) to the UE.

[0287] Exemplarily, when the first AMF obtains that its own energy consumption exceeds a certain predetermined value, or the energy consumption per unit time exceeds a certain predetermined value, or the energy efficiency is lower than a certain predetermined value, or receives an energy saving notification, or an energy efficiency optimization notification, or a reselection network device indication from the OAM / EENF / NWDAF, it initiates the deregistration process.

[0288] Exemplarily, when the UE is in the registered state, the first AMF sends a deregistration request message to the UE.

[0289] Exemplarily, the deregistration reason value carried in the above deregistration request message is network energy saving, or the network device has high energy consumption / low energy efficiency. Exemplarily, a reregistration indication may be carried in the above deregistration request message.

[0290] Exemplarily, an energy-saving backoff timing value may also be carried in the above deregistration request message.

[0291] Step 23: The UE sends a registration request message (i.e., registration request) to the first AMF.

[0292] Exemplarily, if a reregistration indication is carried in the deregistration request message, the UE initiates reregistration and sends a registration request.

[0293] Exemplarily, after receiving the registration request message from the UE, the first AMF may perform the operations of the first embodiment above.

[0294] Embodiment 3: Combining the above Embodiment 2, taking the first network element as the first AMF as an example, an exemplary description is given of the process in which the first AMF rejects the UE's registration request.

[0295] Exemplarily, as Figure 7 shown, the above energy efficiency or energy consumption optimization method may include the following steps 31 to 33:

[0296] Step 31: The first AMF obtains first information.

[0297] Step 32: The UE sends a registration request message to the first AMF.

[0298] Step 33: The first AMF sends a rejection registration message to the UE.

[0299] Exemplarily, when the first AMF determines that its own energy consumption is high or its energy efficiency is low, it rejects the UE's registration.

[0300] Exemplarily, the rejection registration reason is carried in the rejection registration message, for example, energy saving or energy efficiency optimization.

[0301] Embodiment 4: Taking the first network element as the first SMF (SMF1) and the third network element as the second SMF as an example, an exemplary description is given of the process of performing SMF reselection and the SMF instructing the AMF to select an SMF with low energy consumption and high energy efficiency during the process of first releasing the PDU session and then reconstructing the PDU session.

[0302] Exemplarily, asFigure 8 As shown, the above energy efficiency or energy consumption optimization method may include the following steps 41 to 47:

[0303] Step 41: The first SMF obtains the first information.

[0304] Step 42: The first SMF sends a network element reselection indication (i.e., the second network element reselection indication) to the AMF.

[0305] Exemplarily, the network element reselection indication can be carried by Nsmf_PDUSession_SMContextStatusNotify, and the SMF reselection indication or energy saving or high energy consumption or low energy efficiency indication can be carried in the network element reselection indication.

[0306] Exemplarily, when the UE has established a PDU session, if SMF1 obtains that its own energy consumption exceeds a certain predetermined value, or the energy consumption per unit time exceeds a certain 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 certain predetermined value, or receives an energy saving notice, or an energy efficiency optimization notice, or a network device reselection indication from OAM / EENF / NWDAF / PCF, it sends a network element reselection indication to the AMF to initiate the SMF reselection operation.

[0307] Step 43: The AMF sends a response message to the first SMF.

[0308] Exemplarily, the response message can be carried by Nsmf_PDUSession_SmcontextstatusNotifyResponse.

[0309] Step 44: The first SMF sends a PDU session release command to the UE, carrying a reconstruction indication and a release reason value of energy saving or high energy consumption or low energy efficiency.

[0310] Step 45: The UE sends a PDU session establishment request (i.e., PDU session establishmentreques) to the AMF.

[0311] Exemplarily, the UE initiates a PDU session establishment request according to the reconstruction indication.

[0312] Step 46: The AMF obtains the second SMF.

[0313] Exemplarily, when the AMF receives the PDU session establishment request from the UE, it 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.

[0314] Step 47: The AMF sends a PDU session establishment request to the second SMF.

[0315] Exemplarily, the PDU session establishment request can be carried by Nsmf_PDUSession_CreateSMContextRequest.

[0316] Exemplarily, the AMF may delete the SMF reselection indication or energy saving or high energy consumption or low energy efficiency indication from SMF1 to avoid SMF1 not being selected all the time in the subsequent PDU session establishment.

[0317] Exemplarily, after step 47, the UE, the AMF and the second SMF execute the PDU session establishment process.

[0318] Embodiment 5: Taking the first network element as the SMF, the second network element as the first UPF, and the third network element as the second UPF as an example, the process of reselection of the UPF during the process of first releasing the PDU session and then reconstructing the PDU session is exemplarily described.

[0319] Exemplarily, as Figure 9 shown, the above energy efficiency or energy consumption optimization method may include the following steps 51 to 55:

[0320] Step 51: The SMF obtains the first information.

[0321] Step 52: The SMF sends a PDU release request message (i.e., PDU session release command) to the UE.

[0322] Exemplarily, the reconstruction indication and the release cause value of energy saving or high energy consumption or low energy efficiency can be carried in the PDU session release command.

[0323] Exemplarily, when the UE has already established a PDU session, the SMF obtains that the energy consumption of the first UPF (i.e., UPF1) exceeds a certain predetermined value, or the energy consumption per unit time exceeds a certain 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 certain predetermined value, or receives an energy saving notification, or an energy efficiency optimization notification, or an indication of reselection of the UPF from the OAM / EENF / NWDAF, the SMF sends a PDU release request message to perform UPF reselection.

[0324] Step 53: The UE sends a PDU session establishment request (i.e., PDU session establishment request) to the AMF.

[0325] Exemplarily, the UE can initiate a PDU session establishment request according to the reconstruction indication.

[0326] Step 54: The AMF sends a PDU session establishment request to the SMF.

[0327] Exemplarily, the above PDU session establishment request can be carried by Nsmf_PDUSession_CreateSMContextRequest.

[0328] Step 55: The SMF obtains the second UPF.

[0329] Exemplarily, upon receiving the Nsmf_PDUSession_CreateSMContext Request from the AMF, the SMF selects the second UPF with low energy consumption / high energy efficiency (i.e., UPF2 different from UPF1).

[0330] Exemplarily, the SMF can delete the energy consumption related information of the obtained UPF.

[0331] Exemplarily, after step 54, the UE, AMF, SMF, and UPF2 execute the PDU session establishment process. Exemplarily, the SMF establishes an N4 session with the second UPF.

[0337] Exemplarily, the reason value of the network device's energy saving or high energy consumption or low energy efficiency can be carried in the SMF reselection indication.

[0338] Exemplarily, when there is already a PDU session established by SMF1 and the first UPF (UPF1) for the UE, if SMF1 obtains that its energy consumption exceeds a certain predetermined value, or its energy consumption per unit time exceeds a certain predetermined value, or its energy efficiency (such as the amount of data transmitted per unit of specific energy consumption) is lower than a certain predetermined value, or receives an energy-saving notice from OAM / EENF / NWDAF, or an energy efficiency optimization notice, or an indication to reselect SMF and / or UPF, SMF1 performs an operation of first establishing a PDU session and then releasing the PDU session to replace SMF1.

[0339] Step 63: The AMF sends a PDU session modification command to the UE.

[0340] Exemplarily, the PDU session modification command carries an indication to reconstruct the PDU session, and may also carry a reason value for reconstruction, such as network energy saving, high energy consumption, or low energy efficiency.

[0341] Step 64: The UE sends a confirmation message to the AMF.

[0343] Step 65: The AMF forwards the UE's confirmation message to the first SMF.

[0344] Step 66: The first SMF sends a confirmation message to the AMF.

[0345] Exemplarily, the above confirmation message can be carried by the Nsmf_PDUSession_UpdateSMContext Reponse.

[0359] Exemplarily, this message may also carry a cause value for energy conservation of the network device, or high energy consumption, or low energy efficiency.

[0360] Exemplarily, in the case where the UE already has a PDU session established through SMF1 and UPF1, when SMF1 obtains that the energy consumption of UPF1 exceeds a certain predetermined value, or the energy consumption per unit time exceeds a certain predetermined value, or the energy efficiency (such as the amount of data transmitted per unit time with a specific energy consumption) is lower than a certain predetermined value, or receives an energy conservation notice, or an energy efficiency optimization notice, or an indication to reselect the SMF and / or UPF from the OAM / EENF / NWDAF, SMF1 performs an operation of first establishing a PDU session and then releasing the PDU session to replace UPF1.

[0361] Step 73: The AMF sends a PDU session re - establishment request to the UE.

[0362] Exemplarily, the PDU session re - establishment request can be carried by a PDU session modification command.

[0367] Exemplarily, this acknowledgement message can be carried by an Nsmf_PDUSession_UpdateSMContext request.

[0368] Step 76: The first SMF replies with an acknowledgement message to the AMF.
