[0547] Based on the above embodiments, an embodiment of the present invention further provides a communication method. Figure 7 Schematic diagram of the process of the communication method according to the embodiment of the present invention Figure 7 ; as Figure 7 shown, the method includes:

[0558] A specific example is used below to describe in detail the communication method of the embodiments of the present invention.

[0559] Figure 8 Schematic diagram of the interaction process of the communication method of the embodiments of the present invention Figure 1 ; In this example, the first network function is the EECF, the first function is the AF, the second network function is the AMF, the third network function is the SMF, the access network is the RAN, the fourth network function is the NSACF, the fifth network function is the PCF, and the second function is the NWDAF as an example for description. As Figure 8 shown, the method includes:

[0560] Step 801: The AF sends the first information to the EECF through the NEF, or sends the first information to the EECF without passing through the NEF. The first information includes at least one of the following: application identifier, UE identifier, group identifier, any UE identifier, second information (or referred to as the first energy demand related information).

[0561] In some alternative embodiments, the AF sending the first information to the EECF through the NEF includes: the AF sending a request message (such as an AF request message) to the EEF through the NEF, and the request message includes the first information.

[0562] Wherein, the application identifier may include one or more of the following: App ID, triple, quintuple, FQDN, SDF, IP address.

[0563] In some alternative embodiments, the second information may include one or more of the following:

[0564] The fifteenth information: used to indicate permission or authorization for energy-related processing; or, the fifteenth information is used to permit or authorize energy conservation; or, the fifteenth information includes information related to energy conservation authorization, or the fifteenth information includes information related to energy and / or authorization;

[0565] Target energy-related information;

[0566] First energy-related information;

[0567] Information related to the energy consumption threshold and / or information related to the energy consumption threshold value;

[0568] Information related to energy and / or threshold;

[0569] Energy-related threshold and / or energy-related threshold value;

[0570] Information on target parameters or target metrics for adjustment or optimization.

[0571] Here, the meanings of the above-mentioned various pieces of information can be referred to the descriptions in the foregoing embodiments and will not be elaborated here.

[0572] Step 802a: The EEF determines, according to the first information, to perform at least one of the following steps 803 to 807, or determines all or part of the information in steps 803 to 807.

[0573] Here, the EEF can determine or generate at least one of the following according to all or part of the first information and / or all or part of the energy-related information:

[0574] All or part of the third information, all or part of the fifth information, all or part of the seventh information, all or part of the ninth information, all or part of the eleventh information, sending all or part of the third information, sending all or part of the fifth information, sending all or part of the seventh information, sending all or part of the ninth information, sending all or part of the eleventh information; wherein, the third information corresponds to the first processing of the AMF, the fifth information corresponds to the second processing of the SMF, the seventh information corresponds to the third processing of the RAN, the ninth information corresponds to the fourth processing of the PCF, and the eleventh information corresponds to the fifth processing of the PCF.

[0575] Here, the EEF can determine to perform at least one of the following steps 803 to 807 according to the local configuration, or determine all or part of the information in steps 803 to 807. As a possible implementation, the EEF locally configures the relationship between various parameter or metric adjustments and energy-saving effects. For example: for a paging cycle of 100s, for an AMF that consumes 10W of power to serve a certain UE, if the paging cycle is extended to 400s, the power consumption for serving this UE will be reduced to 5W; for each reduction of 1 in the number of sessions served by the SMF, the power consumption will be reduced by 2W to 4W, etc.

[0576] Step 802b: The EEF can also determine, from the NWDAF, to perform at least one of the following steps 803 to 807, or determine all or part of the information in steps 803 to 807.

[0577] For example, the EEF sends all or part of the first information and / or all or part of the energy-related information to the NWDAF, and receives response information from the NWDAF. The response information may include determining to perform at least one of the following steps 803 to step 807, or determining all or part of the information in steps 803 to step 807.

[0578] It should be noted that either step 802a or step 802b is selected for execution.

[0579] One or more of the following steps 803 to step 807 can be executed, without a specific order.

[0580] Step 803: The EEF sends third information to the AMF. The third information includes at least one of the following: UE identifier, group identifier, deregistration-related information, paging-related information, periodic registration update timer, UE-slice MBR-related information, DRX-related information, UE-AMBR-related information, and energy demand information related to the AMF.

[0581] Among them, the deregistration-related information includes at least one of the following: access type, reason value. The reason value is related to energy, such as energy-saving requirements.

[0582] Among them, the paging-related information includes at least one of the following: paging cycle, paging range. Optionally, the paging cycle can also be referred to as the target paging cycle, and the paging range can also be referred to as the target paging range.

[0583] Among them, the energy demand information related to the AMF is the demand for the AMF. For example, the energy demand information related to the AMF requires the AMF to reduce the energy consumption of a certain UE to less than 40% of the current level, but not less than 1W. That is to say, the EEF can send specific adjustment content (such as paging cycle, paging range, periodic registration update timer, DRX-related information, UE-slice MBR, UE-AMBR) to the AMF, or send the energy demand information related to the AMF, and let the AMF decide how to perform energy adjustment or optimization by itself.

[0584] Here, the EEF can directly send the third information to the AMF, or send the third information to the AMF via at least one network function. Such network functions can be, for example, SMF, PCF, etc.

[0585] Here, after the AMF receives the third piece of information, it performs the first process. The first process includes at least one of the following: deregistering at least one UE, modifying or adjusting the paging-related information related to at least one UE, modifying or adjusting the periodic registration update timer information of at least one UE, modifying or adjusting the UE-slice MBR-related information of at least one UE and / or at least one slice, sending the DRX-related information to the access network, sending the DRX-related information to the access network via at least one network function, sending the periodic registration update timer information to the UE, sending the periodic registration update timer information to the UE via at least one function or entity, modifying or adjusting the UE-AMBR-related information, sending the UE-AMBR-related information to the access network, and sending the UE-AMBR-related information to the access network via at least one network function.

[0586] Specifically, this example may further include at least one of the following steps:

[0587] Step 803a: Perform at least one of the following: modifying or adjusting the periodic registration update timer information, modifying or adjusting the UE-slice MBR-related information, modifying or adjusting the paging-related information, and modifying or adjusting the UE-AMBR-related information.

[0588] Here, the modifying or adjusting the periodic registration update timer information may specifically be modifying or adjusting the periodic registration update timer information of at least one UE. The modifying or adjusting the UE-slice MBR-related information may specifically be modifying or adjusting the UE-slice MBR-related information of at least one UE and / or at least one slice. The modifying or adjusting the UE-AMBR-related information may specifically be modifying or adjusting the UE-AMBR-related information of at least one UE.

[0589] Here, the paging-related information may include a paging cycle and / or a paging range. The modifying or adjusting the paging-related information may specifically be modifying or adjusting the paging cycle and / or the paging range related to at least one UE.

[0590] Step 803b: Send a deregistration request to the RAN;

[0591] Step 803c: Send at least one of the periodic registration update timer information, the DRX-related information, the UE-AMBR-related information, and the UE-slice MBR-related information to the RAN.

[0592] In other examples, step 803 may also be that the AMF sends at least one of the periodic registration update timer information, the DRX-related information, the UE-AMBR-related information, and the UE-slice MBR-related information to the RAN through other network functions.

[0593] In other alternative examples, it may further include: the AMF sends periodic registration update timer information to the UE; and / or, the periodic registration update timer information is sent to the UE via at least one function or entity.

[0594] The advantage of this is that these parameters can all affect power consumption: when the number of registered users is smaller, the network-side power consumption is lower; when the periodic registration update timer has a longer time, the frequency of periodic registration updates is lower, that is, the signaling frequency is lower, so the power consumption is lower; when the DRX is awake, it consumes more power than when it is in the sleep state, so when the wake-up duration in the idle-state DRX cycle is lower, the power consumption is lower; when the paging cycle is higher, paging is less frequent, so the power consumption is lower; when the paging range is smaller, the energy required to perform one paging is also lower.

[0595] Step 804: The EEF sends fifth information to the SMF, and the fifth information includes at least one of the following: session identifier, session release information, session context release information, and SMF-related energy requirement information.

[0596] Here, the session release information or the session context release information may include a session release instruction.

[0597] Here, the SMF-related energy requirement information is a requirement for the SMF. The SMF-related energy requirement information requires the SMF to reduce the power consumption for a certain UE to less than 40% of the current value, but not less than 1 W. That is to say, the EEF can send specific adjustment content (session release-related information, session context release-related information, etc.) to the SMF, or send SMF-related energy requirement information to the SMF, and the SMF decides how to make adjustments / optimizations by itself.

[0598] Here, the EEF can directly send the fifth information to the SMF, or send the fifth information to the SMF via at least one network function, and this network function can be, for example, the PCF, etc.

[0599] Here, after receiving the fifth information, the SMF performs a second process, and the second process includes at least one of the following: releasing at least one session, releasing the context of at least one session.

[0600] Specifically, this example may further include the following steps:

[0601] Step 804a: Perform at least one of the following: releasing at least one session, releasing the context of at least one session.

[0602] The advantage of this is that these parameters can all affect power consumption: when the number of sessions is smaller, the network-side power consumption is lower, and the power consumption can be reduced.

[0603] Step 805: The EEF sends the seventh information to the RAN, where the seventh information includes at least one of the following: UE identifier, group identifier, radio access bearer release related information, DRX related information, UE-slice MBR related information, UE-AMBR related information, and RAN related energy requirement information.

[0604] Here, the radio access bearer release related information may indicate initiating / executing an access network release and / or a radio access bearer release.

[0605] Here, the RAN related energy requirement information is the requirement for the RAN. For example, the RAN related energy requirement information requires the RAN to reduce the energy consumption for a certain UE to below 40% of the current level but not less than 1W. That is to say, the EEF can send specific adjustment contents (radio access bearer release related information, DRX cycle) to the RAN, or send the RAN related energy requirement information to the RAN, and the RAN decides how to make adjustments / optimizations by itself.

[0606] Here, the EEF can directly send the seventh information to the RAN, or send the seventh information to the RAN via at least one network function, which may be, for example, the AMF, SMF, etc.

[0607] Here, after receiving the seventh information, the RAN performs the third processing. The third processing includes at least one of the following: modifying or adjusting the DRX related information, releasing the radio access bearer related information of at least one UE, modifying or adjusting the UE-slice MBR related information of at least one UE and / or at least one slice, and modifying or adjusting the UE-AMBR related information of at least one UE.

[0608] Specifically, this example may further include the following steps:

[0609] Step 805a: Perform one or more of the following: modifying or adjusting the DRX related information, releasing the radio access bearer, modifying or adjusting the UE-slice MBR related information, and modifying or adjusting the UE-AMBR related information.

[0610] The advantage of doing this is that these parameters can all affect the energy consumption: when the radio access bearer connection is not used, the energy consumption on the network side is lower; when the DRX wakes up, it consumes more power than when it is in the sleep state. Therefore, when the wake-up duration in the idle state DRX cycle is lower, the energy consumption is lower.

[0611] Step 806: The EEF sends the ninth information to the NSACF, including at least one of the following: the maximum number of UEs, the maximum number of sessions, and the NSACF related energy requirement information.

[0612] Here, the energy demand information related to the NSACF is the demand for the NSACF. For example, the energy demand information related to the NSACF requires that the energy consumption of the NSACF for a certain UE be reduced to less than 40% of the current level, but not less than 1 W. That is to say, the EEF can send specific adjustment content (such as the maximum number of UEs, the maximum number of sessions) to the NSACF, or send the energy demand information related to the NSACF, and the NSACF can decide how to make adjustments / optimizations by itself.

[0613] Here, the EEF can directly send the ninth information to the NSACF, or send the ninth information to the NSACF via at least one network function, which can be, for example, the SMF, PCF, etc.

[0614] Here, after receiving the ninth information, the NSACF performs the fourth process. The fourth process includes at least one of the following: modifying or adjusting the maximum number of UEs, modifying or adjusting the maximum number of sessions.

[0615] Specifically, this example may further include the following steps:

[0616] Step 806a: Modifying or adjusting the maximum number of UEs, modifying or adjusting the maximum number of sessions.

[0617] Step 807: The EEF sends the eleventh information to the PCF, including at least one of the following: periodic registration update timer information, DRX-related information, UE-AMBR-related information, session release information, session context release information, UE-slice MBR-related information, the energy demand information related to the PCF.

[0618] Here, the energy demand information related to the PCF is the demand for the PCF. For example, the energy demand information related to the PCF requires that the energy consumption of the PCF for a certain UE be reduced to less than 40% of the current level, but not less than 1 W. That is to say, the EEF can send specific adjustment content (such as UE-slice MBR) to the PCF, or send the energy demand information related to the PCF, and the PCF can decide how to make adjustments / optimizations by itself.

[0619] Here, the EEF can directly send the eleventh information to the PCF, or send the eleventh information to the PCF via at least one network function, which can be, for example, the SMF, etc.

[0620] Here, after receiving the eleventh piece of information, the PCF performs a fifth process. The fifth process includes at least one of the following: modifying or adjusting UE-slice MBR related information and / or UE-AMBR related information, sending UE-slice MBR related information and / or UE-AMBR related information to at least one of the access network, the second network function, and the third network function, sending UE-slice MBR related information and / or UE-AMBR related information to at least one of the access network, the second network function, and the third network function via at least one network function, sending DRX related information to the second network function, sending DRX related information to the second network function via at least one network function, sending periodic registration update timer information to the second network function, sending periodic registration update timer information to the second network function via at least one network function, sending session release information to the third network function, and sending session release information to the third network function via at least one network function.

[0621] Specifically, this example may further include at least one of the following steps:

[0622] Step 807a: Modifying or adjusting UE-slice MBR related information and / or UE-AMBR related information;

[0623] Step 807b: Sending UE-slice MBR related information and / or UE-AMBR related information.

[0624] Here, the sending of UE-slice MBR related information may specifically be sending UE-slice MBR related information to at least one of the RAN, AMF, and SMF, or may also be sending UE-slice related MBR information to at least one of the RAN, AMF, and SMF via at least one network function. Correspondingly, the sending of UE-AMBR related information may specifically be sending UE-AMBR related information to at least one of the RAN, AMF, and SMF, or may also be sending UE-AMBR information to at least one of the RAN, AMF, and SMF via at least one network function.

[0625] Step 808: Optionally, the EEF may send a notification to the AF, and the notification may include at least one of the following: application identifier, UE identifier, group identifier, and fourteenth information related to energy adjustment or optimization.

[0626] Here, the fourteenth information includes at least one of the following:

[0627] Sixteenth information, which is used to indicate that energy adjustment or optimization has been performed;

[0628] All or part of the third information; the third information includes relevant information and / or fourth information for the second network function to perform a first process related to energy adjustment or optimization, and the fourth information is related to energy adjustment or optimization;

[0629] All or part of the fifth information; the fifth information includes relevant information and / or sixth information for the third network function to perform a second process related to energy adjustment or optimization, and the sixth information is related to energy adjustment or optimization;

[0630] All or part of the seventh information; the seventh information includes relevant information and / or eighth information for the access network to perform a third process related to energy adjustment or optimization, and the eighth information is related to energy adjustment or optimization;

[0631] All or part of the ninth information; the ninth information includes relevant information and / or tenth information for the fourth network function to perform a fourth process related to energy adjustment or optimization, and the tenth information is related to energy adjustment or optimization;

[0633] The energy-related information after adjustment or optimization.

[0634] In this example, all or part of the above information can be the content specifically executed. For example, how many sessions are released, how much the DRX cycle is modified, how much the transmission rate is reduced, and so on.

[0635] Here, the energy-related information after adjustment or optimization may include at least one of the following: energy consumption, energy efficiency, renewable energy usage rate, green energy usage rate, etc. It can be an absolute value (for example, the power consumption is reduced to 100W or the energy consumption is reduced to 50W·h after optimization) and / or a relative value (the energy consumption is reduced by 40% after optimization).

[0636] Here, the EEF can communicate directly with the AF or communicate via at least one network function, which can be, for example, the NEF, etc.

[0640] Step 902: The NEF sends all or part of the information in the first piece of information to the EECF.

[0641] Step 903: The EECF obtains energy saving authorization information from the UDM. For example, the energy saving authorization information is sent to the EECF included in the subscription information.

[0642] This step is an optional step. For example, if the energy saving authorization-related information is not included in the first piece of information obtained by the EECF, step 903 may be executed.

[0643] As another optional implementation, if the energy saving authorization-related information is not included in the first piece of information, step 903 may also be executed.

[0656] Step 907: The EECF sends the third adjustment information to the PCF, which is used to instruct to adjust the UE-Slice-MBR; and / or, the third adjustment information includes the UE-Slice-MBR. The third adjustment information may also be referred to as the third policy adjustment information.

[0657] Here, the UE-Slice-MBR corresponds to the granularity of the slice and / or the granularity of the UE.

[0658] As an alternative implementation, the third adjustment information is used to instruct to adjust the UE-Slice-MBR, which is used to instruct the PCF to adjust these information, but may not include the adjusted value, and the PCF can determine the adjusted value by itself.
