[0197] It can be understood that in the embodiments of the present application, the second information can correspond to multiple network functions, and there are multiple pieces of information, each of which is used to describe a network function. For each network function, the third network function / third network element can determine its priority information according to its energy information, carbon efficiency information, carbon emission information, energy efficiency information, or energy consumption information. For example, the higher the carbon efficiency, the higher the priority. In addition, the third network function / third network element can also determine its priority information for each network function according to its multiple pieces of information, which is not limited in the embodiments of the present application.

[0198] It should be noted that in the embodiments of the present application, in combination with the above network function selection or reselection method applied to the fourth network function / fourth network element, the third network function / third network element can also send the third information to the fourth network function / fourth network element for the fourth network function / fourth network element to send system information according to the third information.

[0200] The following combines specific application scenarios to exemplarily illustrate the above Figures 1 to 5 shown process.

[0201] Figure 6 This is an exemplary interaction diagram for selecting or reselecting the AMF provided by the embodiments of the present application. As Figure 6 shown, in the embodiments of the present application, selecting or reselecting the AMF mainly includes the following steps:

[0202] S601. The OAM / NWDAF / energy efficiency control network element / energy consumption control network element (third network function / third network element) obtains the energy consumption / energy efficiency information of the AMF.

[0203] It should be noted that the / NWDAF / energy efficiency control network element / energy consumption control network element obtains the energy consumption / energy efficiency information of the AMF, which can specifically be calculated according to the obtained statistical information. The energy consumption / energy efficiency information of the AMF includes at least one of the following:

[0204] Energy information: including the energy type used to describe the AMF as renewable energy or non-renewable energy, and / or, the proportion of renewable energy;

[0205] Carbon efficiency information: used to describe the high or low carbon efficiency of the AMF, which can be high, medium, low, carbon efficiency level values, etc.; for example, it can be divided into five carbon efficiency levels from 1 to 5. Level 1 indicates that the carbon emissions of the AMF are much lower than the average carbon emissions of a certain regional network function, with the highest carbon efficiency; levels 2 to 4 indicate that the carbon emissions of the AMF are close to or slightly exceed the average carbon emissions of a certain regional network function, and level 5 indicates that the carbon emissions of the AMF are much higher than the average carbon emissions of a certain regional network function, with the lowest carbon efficiency;

[0206] Carbon emission information: used to describe the carbon emissions of the AMF, for example, the magnitude relationship between the carbon emissions of the AMF and the average carbon emissions of a certain regional network function, etc.;

[0207] Energy efficiency information: used to describe the high or low energy efficiency of the AMF, for example, the data volume / energy consumption of the AMF within the statistical time window.

[0208] Energy consumption information: used to describe the energy consumption status of the AMF, such as low, medium, high, or specific percentage values such as 20%, 50%, etc.

[0209] Priority information, OAM / NWDAF / energy efficiency management network element / energy consumption management network element can determine the priority information of the AMF based on any of the above information. For example, set a higher priority for the AMF for renewable energy, or the AMF with a high proportion of renewable energy, or the AMF with high carbon efficiency, or the AMF with low carbon emissions, or the AMF with high energy efficiency.

[0210] S602. OAM / NWDAF / energy efficiency management network element / energy consumption management network element configure the energy consumption / energy efficiency information of the AMF for the RAN (the fourth network function / fourth network element).

[0211] It should be noted that the energy consumption / energy efficiency information of the AMF is as described in the above step S601 and will not be elaborated here.

[0212] Optionally, OAM / NWDAF / energy efficiency management network element / energy consumption management network element can also configure the priority information of the AMF for the RAN at the same time, or only configure the priority information of the AMF.

[0213] S603. The terminal (User Equipment, UE) sends an access request to the RAN.

[0214] It should be noted that the access request may include AMF identification information, slice information, etc., which are not limited in the embodiments of this application.

[0215] S604. The RAN selects or reselects the AMF according to the UE access request and the information configured by the OAM / NWDAF / energy efficiency management network element / energy consumption management network element.

[0216] It should be noted that the RAN selects or reselects the AMF based on the UE access request and the information configured by the OAM / energy efficiency management network element / energy consumption management network element, specifically including:

[0217] If the UE access request includes a unique AMF identifier, the RAN preferentially selects or reselects the AMF;

[0218] If the UE access request only includes the AMF area identifier or the AMF set identifier, or only provides slice information, the RAN first determines the candidate AMFs that meet the UE requirements based on the UE access request, and then makes a selection or reselection according to the information configured by the OAM / energy efficiency management network element / energy consumption management network element, such as preferentially selecting or reselecting the AMF with renewable energy, or the AMF with higher carbon efficiency, or the AMF with higher energy efficiency. If the OAM / NWDAF / energy efficiency management network element / energy consumption management network element only configures priorities, the RAN selects or reselects the AMF with a higher priority.

[0219] Figure 7 This is an exemplary interaction diagram for selecting or reselecting a network function (NF) provided by an embodiment of the present application. As Figure 7 shown, in the embodiment of the present application, the selection or reselection of the NF mainly includes the following steps:

[0220] S701. The OAM / NWDAF / energy efficiency management network element / energy consumption management network element (the third network function / the third network element) obtains the energy consumption / energy efficiency information of multiple NFs.

[0221] It should be noted that the OAM / NWDAF / energy efficiency management network element / energy consumption management network element obtains the energy consumption / energy efficiency information of multiple NFs, which can specifically be calculated based on the obtained statistical information. The energy consumption / energy efficiency information of each NF includes at least one of the following: energy information, carbon efficiency information, carbon emission information, energy efficiency information, energy consumption information, and priority information.

[0222] Among them, for each NF, the OAM / NWDAF / energy efficiency management network element / energy consumption management network element can determine its priority information based on its energy information, carbon efficiency information, carbon emission information, energy efficiency information, or energy consumption information.

[0223] S702. The NF requester (the first network function / the first network element) sends an NF discovery request to the NRF (the second network function / the second network element).

[0224] It should be noted that the NF discovery request carries information such as the data network name (DNN), slice information, terminal access technology type, NF service area, and UE location.

[0225] S703. The NRF determines a candidate NF list based on the NF discovery request.

[0226] S704. The NRF requests energy consumption / energy efficiency information of the candidate NFs from the OAM / NWDAF / energy efficiency management network element / energy consumption management network element.

[0227] It should be noted that the identification information or address information of the candidate NF list is carried in the request.

[0228] S705. The OAM / NWDAF / energy efficiency management network element / energy consumption management network element feeds back the energy consumption / energy efficiency information of the candidate NFs to the NRF.

[0229] It should be noted that the energy consumption / energy efficiency information of the candidate NFs is as described in step 1 above and will not be elaborated here.

[0230] Optionally, the OAM / NWDAF / energy efficiency management network element / energy consumption management network element can also feed back the priority information of each candidate NF to the NF requester at the same time, or only feed back the priority information of each candidate NF.

[0231] S706. The NRF determines the priority information based on the energy consumption / energy efficiency information of the candidate NFs.

[0232] It should be noted that step S706 is optional and can be executed when the OAM / NWDAF / energy efficiency management network element / energy consumption management network element does not feed back the priority information of the candidate NFs. Of course, it can also not be executed, and there is no limitation.

[0233] It should be noted that the NRF can determine the priority information based on the energy information, carbon efficiency information, carbon emission information, energy efficiency information, or energy consumption information of the candidate NFs. For example, a higher priority can be set for candidate NFs for renewable energy, or candidate NFs with high carbon efficiency, or candidate NFs with high energy efficiency, or candidate NFs in a low energy consumption state.

[0234] S707. The NRF feeds back the candidate NF list to the NF requester.

[0235] It should be noted that the candidate NF list includes at least one of the following: the address information of the candidate NF, energy consumption / energy efficiency information, priority information, and capacity information.

[0236] S708. The NF requester selects or reselects an NF from the candidate NF list.

[0237] It should be noted that Figure 7 The shown process is applicable to the selection or reselection of the SMF and UPF. Just replace the NF with the SMF or UPF, and replace the candidate NF list and related information with the candidate SMF list or candidate UPF list and related information, which will not be elaborated here.

[0238] Figure 8 An exemplary interaction diagram for cell selection or reselection provided by an embodiment of this application.

[0239] As Figure 8 shown, in an embodiment of this application, cell selection or reselection mainly includes the following steps:

[0240] S801. The OAM / NWDAF / energy efficiency management network element / energy consumption management network element (third network function / third network element) obtains the energy consumption / energy efficiency information of the RAN (fourth network function / fourth network element).

[0241] It should be noted that the OAM / NWDAF / energy efficiency management network element / energy consumption management network element obtains the energy consumption / energy efficiency information of the RAN, which can specifically be calculated based on the obtained statistical information. The energy consumption / energy efficiency information of the RAN includes at least one of the following: energy information, carbon efficiency information, carbon emission information, energy efficiency information, energy consumption information, priority information.

[0242] Among them, for the RAN, the OAM / NWDAF / energy efficiency management network element / energy consumption management network element can determine its priority information according to its energy information or carbon efficiency information or carbon emission information or energy efficiency information.

[0243] S802. The OAM / NWDAF / energy efficiency management network element / energy consumption management network element configures the energy consumption / energy efficiency information of the RAN for the RAN.

[0244] It should be noted that the energy consumption / energy efficiency information of the RAN is as described in step S801 above and will not be elaborated here.

[0245] After step 2, the RAN can execute one of the following steps S803a, S803b, and S803c:

[0246] S803a. The RAN carries the energy consumption / energy efficiency information of the RAN in the system message according to the information configured by the OAM / NWDAF / energy efficiency management network element / energy consumption management network element;

[0247] S803b. The RAN carries the cell priority of the RAN in the system message according to the information configured by the OAM / NWDAF / energy efficiency management network element / energy consumption management network element; for example, higher priorities are set for renewable energy cells and cells with high carbon efficiency / energy efficiency;

[0248] S803c. The RAN carries offset information in the system message according to the information configured by the OAM / NWDAF / energy efficiency management network element / energy consumption management network element; for example, smaller offsets are set for renewable energy cells and cells with high carbon efficiency / energy efficiency; the RAN broadcasts the offset information set based on the energy consumption / energy efficiency information in the system broadcast message.

[0249] S804. The RAN sends system information.

[0250] S805. The UE performs cell selection or reselection based on the received information.

[0251] It should be noted that the UE first determines a list of candidate cells that meet the signal strength and signal quality; the UE further combines energy consumption / energy efficiency information in the candidate cell list for selection or reselection, such as preferentially selecting or reselecting a renewable energy cell, or a cell with higher carbon efficiency / energy efficiency (corresponding to step S803a); or, the UE further combines the cell priority in the candidate cell list for selection or reselection, such as preferentially selecting or reselecting a cell with a higher priority (corresponding to step S803b); or, when the UE selects or reselects a cell, it determines the signal strength and signal quality according to the offset information and performs cell selection or reselection (corresponding to step S803c).
