[0323] In the embodiments of this application, the term "and / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates an "or" relationship between the associated objects before and after.

[0324] In the embodiments of this application, the term "a plurality of" means two or more, and other quantifiers are similar.

[0325] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0326] To clearly understand the technical solution of this application, the solutions of the prior art will be introduced in detail first.

[0327] A communication system consists of various communication devices, which consume energy (such as electricity, etc.) when providing communication services. The energy consumption of the entire communication system is the sum of the energy consumptions of all communication devices in the system. The energy consumption of a communication device refers to the energy consumed by the communication device to support communication operations and complete communication tasks. The energy consumption can be obtained by measuring and calculating the power of the device over a period of time. The energy efficiency of a communication system / communication device reflects the efficiency of energy consumption, that is, the ratio of the provided communication services to the consumed energy. For example, it can be defined as the ratio of the amount of data transmitted to the energy consumption, or the ratio of the covered ( / served) communication area to the energy consumption. The energy efficiency can be targeted at the entire network, subnets (such as radio access networks, individual network devices, communication sites (such as data centers), terminals, etc.).

[0328] However, in order to support the functions and performance of mobile communication, current mobile communication networks and devices have high energy consumption, which in turn leads to low energy efficiency.

[0329] To solve the problem in the prior art that the energy consumption of mobile communication networks and devices is high, which in turn leads to low energy efficiency, it is possible to optimize and enhance the existing communication processes or network processes by effectively using the information in the network, such as network energy-saving strategies or energy-saving auxiliary information, so as to further reduce the energy consumption of communication systems and communication devices and improve the energy efficiency.

[0330] Therefore, based on the above research, the energy-saving method and device proposed in this application are presented. In this application, based on the information in the network (such as network data analysis information, including statistical and prediction information on terminals, applications, and network communication behaviors, etc.; subscription data), a solution to enhance processes such as policy control, mobility management, and session management in the mobile communication network is proposed to achieve the purpose of reducing network energy consumption and improving network energy-saving performance.

[0331] Among them, the method and the device are based on the same inventive concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0391] In the embodiments of the present application, the PCF requests (including subscribing to information multiple times or requesting information once, which will not be elaborated below) the analysis information of the terminal and / or application ( / service) (which may refer to network data analysis information, which will not be elaborated below) from the Network Data Analytics Function (NWDAF for short).

[0399] The AMF and the SMF perform energy-saving operations based on UE abnormal behavior analysis information, etc., including performing energy-saving operations by themselves and assisting other network functions (such as access network AN, UPF).

[0400] The SMF provides energy-saving assistance information related to UE session management to the access network (AN); specifically, the SMF can determine one or more access network nodes that can perform energy-saving operations based on the network energy consumption control information obtained from the NEMF or the Network Exposure Function (NEF), or based on the energy consumption-related analysis information of the access network and / or the cell obtained from the NWDAF, and provide the UE session management-related information (such as UE session management-related capabilities (including activation condition information), UE communication analysis information) to these one or more access network nodes as energy-saving assistance information.

[0401] The AN provides cell energy consumption-related information (such as information about cells with high energy efficiency or high resource utilization rate) to the UE for the UE to use for cell selection, cell reselection, or handover (such as conditional handover initiated by the UE).

[0402] The SMF provides energy-saving-related session control information (such as releasing a session or modifying QoS parameters) to the UPF, or provides UE session management-related information (such as UE session management-related capabilities (including activation condition information), UE communication analysis information) to the UPF as energy-saving assistance information.

[0403] The SMF requests analysis information related to UE communication (i.e., session management) from the NWDAF. The NWDAF provides the SMF with analysis information related to UE communication, including the communication time of the UE (communication cycle, start time, duration, etc.), data traffic characteristics (such as network slice identifier S-NSSAI, data network name DNN, IP address, port number, etc.), uplink and downlink data traffic, and / or application / service characteristics (such as application identifier, start time, duration); uplink and downlink data traffic of all UEs in a specific cell, etc.).

[0404] The first network function entity itself performs energy-saving operations related to terminal session management based on capabilities related to terminal communication (here referring to session management, which will not be elaborated below), including activation condition information, subscribed data, network policies, network energy consumption control information, and / or terminal communication analysis information (here referring to analysis information related to terminal session management), etc. For example: 1) Based on the session management-related capabilities of the terminal (here referring to the user equipment (abbreviated as UE) in English, which will not be elaborated below) and their activation conditions and communication analysis information, only activate the control functions of real-time ( / immersive) multimedia communication, satellite communication, or multicast / broadcast communication within specific time and / or specific areas, such as session processing related to real-time ( / immersive) multimedia communication, satellite communication, or multicast / broadcast communication; 2) If the uplink and downlink data traffic of all UEs in a specific time period and / or specific area is low, then reduce the service capabilities of a specific tracking area (TA) (for example: reduce the server processing frequency of a specific area or reduce the allocated resources), so as to reduce the energy consumption of the communication system and communication equipment, and thus improve energy efficiency.

[0405] The SMF requests network energy consumption control information from the NEMF. The request message may include the area (here referring to the energy-saving area), time period (here referring to the energy-saving time period), network slice identifier, NF information (here referring to network function entity information, such as NF identifier, NF type, NF set identifier, etc.). The NEMF provides the corresponding network energy consumption control information to the SMF according to the request of the SMF.

[0406] In the embodiments of this application, the SMF requests energy consumption-related analysis information of the access network and / or cell (AN / cell) from the NWDAF. The NWDAF provides the energy consumption-related analysis information of the access network and / or cell to the SMF (for example: predicted energy consumption, energy efficiency, resource utilization rate, etc. of the access network and / or cell).

[0408] The SMF requests abnormal behavior analysis information related to UE communication from the NWDAF, including abnormally large data traffic, abnormal distributed denial of service (DDoS), abnormal data traffic of specific applications ( / services), etc. The NWDAF provides the analysis information related to UE abnormal behavior to the SMF according to the request of the SMF.

[0409] The SMF sends the analysis information of the UE's communication abnormal behavior to the AMF. The AMF provides the analysis information of the UE's mobility and / or communication abnormal behavior to the access network (AN) as energy-saving auxiliary information. Specifically, the AMF can obtain the energy consumption information of the access network and / or the cell based on step 4, and accordingly determine one or more access network nodes that can perform energy-saving operations based on the UE abnormal behavior-related information, and provide the UE abnormal behavior-related information to these one or more access network nodes as energy-saving auxiliary information.

[0410] The AMF sends the analysis information of the UE's mobility abnormal behavior to the SMF. The SMF itself determines to perform energy-saving operations based on the analysis information of the UE's communication and / or mobility abnormal behavior, such as: releasing the session of the abnormal UE, or, releasing the QoS flow corresponding to the abnormal application ( / service) of the UE or reducing its transmission rate, etc. The SMF provides the control information of the PDU session (such as releasing the session or modifying the QoS parameters) to the UPF according to the determined energy-saving operation, or, provides the UE abnormal behavior-related information to the UPF as energy-saving auxiliary information. The SMF provides the control information of the PDU session (such as releasing the session or modifying the QoS parameters) to the UPF according to the determined energy-saving operation, or, provides the UE abnormal behavior-related information to the UPF as energy-saving auxiliary information.

[0412] The first network function entity can perform energy-saving operations based on the energy-saving auxiliary information provided by the terminal or other network function entities, such as: 1) performing relevant mobility management functions only within a specific time and / or specific area according to the UE's mobility management-related capabilities and their effective conditions, mobility analysis information, such as performing the satellite communication terminal location verification function within the time and / or area according to the UE's satellite communication usage time and / or area information; 2) reducing the service capacity of a specific service area (TA) if the number of UEs distributed within a specific time period and / or specific area is small (for example: reducing the server processing frequency of a specific area or reducing the allocated resources). This realizes reducing the energy consumption of the communication system and communication devices, and thus improving the energy efficiency.

[0413] The first network function entity can perform energy-saving operations based on energy-saving related session control information (here refers to the control information of the PDU session) or energy-saving assistance information. For example: 1) Based on the session management related capabilities of the UE (here refers to the terminal session management related capabilities, not repeated below) and their effective conditions, and the UE communication analysis information, only enable the user plane functions of real-time ( / immersive) multimedia communication, satellite communication or multicast / broadcast communication within a specific time and / or specific area, such as the packet processing related to real-time ( / immersive) multimedia communication, satellite communication or multicast / broadcast communication services; 2) Reduce the service capabilities of a specific service area (TA) within a specific time period and / or specific area (for example: reduce the server processing frequency of a specific area or reduce the allocated resources). This can achieve energy consumption reduction of the communication system and communication devices, and thus improve energy efficiency.

The AF determines energy-saving related application ( / service) parameters and / or energy-saving related UE subscription information based on the analysis information of the terminal and / or application ( / service), and the network energy consumption related information or network energy consumption configuration information.

[0415] The AF (through the NEF) provides energy-saving related application ( / service) parameters and / or UE subscription information to the UDR (Unified Data Repository function) or UDM (Unified Data Management function). The UDR or UDM notifies the PCF of the change of the application ( / service) parameters and / or UE subscription information.

[0417] The following will detail the energy-saving method through specific embodiments.

[0418] Exemplarily, in Embodiment 1, the PCF determines a (network) energy-saving strategy for a terminal or an application ( / service) based on the analysis information for the terminal (UE) and / or the application ( / service) and the network energy consumption control information, and provides the energy-saving strategy to the UE, AN, AMF, and SMF.

[0419] See Figure 2 as shown in Figure 2 the interaction diagram of the energy-saving method provided by the embodiments of the present application Figure 1 . The energy-saving method provided in this embodiment includes the following steps:

[0420] Step 1a. The PCF requests the analysis information of the terminal and / or the application ( / service) from the NWDAF (including information subscribed multiple times or requesting information once, which will not be elaborated below), such as the analysis information of the discrete distribution of the terminal and / or the application ( / service) in terms of time and region.

[0421] Step 1b. The NWDAF provides the analysis information of the terminal and / or the application ( / service) to the PCF.

[0422] Step 2a. The NEMF (Network Energy Management Function) requests the analysis information related to network energy consumption from the NWDAF, such as the resource usage prediction information of network slices or network functions (NFs).

[0423] Step 2b. The NWDAF provides the analysis information related to network energy consumption to the NEMF.

[0424] Step 2c. The NEMF determines the network energy consumption control information, such as the energy-saving time period, the corresponding energy-saving region, the working ( / non-working) network slices, and / or network functions, etc.

[0425] Step 3. The PCF requests the network energy consumption control information from the NEMF. The request message may include the region, time period, network slice identifier, NF information (such as NF identifier, NF type, NF set identifier, etc.).

[0426] Step 4. The NEMF provides the corresponding network energy consumption control information to the PCF according to the request of the PCF.

[0427] Step 5. The PCF determines the network energy-saving strategy for the terminal or the application ( / service) based on the analysis information for the terminal and / or the application ( / service) and the network energy consumption control information.

[0428] Step 6. The PCF provides the energy-saving policy for the UE (through the AMF) for the terminal or application ( / service). For example: The UE or a specific application ( / service) preferentially uses a specified network slice, data network, access technology, and / or frequency during the specified energy-saving time period and / or energy-saving area.

[0429] Step 7. The UE performs energy-saving operations according to the energy-saving policy. For example, according to the URSP, when the UE is in the energy-saving area during the energy-saving period, the UE uses the PDU session in the specified network slice to transmit data of the specified application ( / service), including creating or modifying (existing) PDU sessions in the specified network slice to transmit data of the specified application ( / service).

[0430] Step 8. The PCF provides the energy-saving policy to the AN. For example: For a specific UE or application, use a specified network slice during the specified energy-saving time period and energy-saving area; or, during the specified energy-saving time period and energy-saving area, turn off the specified network slice 1 and use the specified network slice 2.

[0431] Step 9. The AN performs energy-saving operations according to the energy-saving policy provided by the PCF, and optionally, also according to the local policy. For example: Provide services to a specific UE or application using a specified network slice during the specified energy-saving time period and energy-saving area; or, during the specified energy-saving time period and energy-saving area, turn off the specified network slice 1 and use the specified network slice 2.

[0432] Step 10. The PCF provides the energy-saving policy related to mobility management to the AMF. For example: It includes a list of identifiers of UEs with high energy consumption, optionally, also includes measurement, statistics, or prediction information on the energy consumed by the UE, and may also include an indication to deregister the UEs with high energy consumption.

[0433] Step 11. The AMF performs energy-saving operations according to the energy-saving policy provided by the PCF, and optionally, also according to the local policy. For example: Deregister the UEs with high energy consumption, or adjust the mobility management parameters of the UE (such as discontinuous transmission DTX parameters), or adjust the UE-related parameters on the RAN side (such as discontinuous transmission DTX parameters) to reduce the energy consumption of the UE on the network.

[0434] Step 12. The PCF provides the energy-saving policy related to session management to the SMF. For example: Adjust the QoS-related policy of the application with high energy consumption; it may also include a list of identifiers of UEs or applications with high energy consumption, optionally, also includes measurement, statistics, or prediction information on the energy consumed by the UE or application ( / service), and an indication to release the PDU sessions of the UEs with high energy consumption, etc.

[0435] Step 13. The SMF performs energy-saving operations according to the energy-saving policy provided by the PCF, and optionally, also according to the local policy. For example, it adjusts the QoS parameters of applications with high energy consumption according to the policy provided by the PCF, releases the PDU session of the UE with high energy consumption, releases the QoS flow (QoS flow) for transmitting applications with high energy consumption, etc.

[0436] Exemplarily, in Embodiment 2, the AF determines application ( / service) parameters related to energy saving and / or UE subscription information related to energy saving based on the analysis information for the terminal and / or application ( / service), and the network energy consumption related information or network energy consumption configuration information. The AF provides the application ( / service) parameters related to energy saving and / or the UE subscription information related to energy saving to the UDM / UDR and the PCF. Based on this, the PCF determines the (network) energy-saving policy for the terminal or application ( / service), and provides the energy-saving policy to the UE, AN (, AMF, and SMF).

[0437] See Figure 3 as shown in Figure 3 the interaction diagram of the energy-saving method provided by the embodiment of the present application Figure 2 . The energy-saving method provided in this embodiment includes the following steps:

[0438] Step 1. The AF requests the NWDAF for the analysis information of the terminal and / or application ( / service), such as the analysis information of the discrete distribution of the terminal and / or application ( / service) in terms of time and region.

[0439] Step 2. The NWDAF provides the AF with the analysis information of the terminal and / or application ( / service).

[0440] Step 3. The AF requests the NEMF (or NEF) for the network energy consumption related information, or requests the OAM for the network energy consumption configuration information. The request message may include information such as region, time period, network slice identifier (such as one or more single network slice selection assistance information S-NSSAI(s)), data network name (DNN), etc.

[0441] Step 4. The NEMF (or NEF) provides the AF with the corresponding network energy consumption related information according to the request of the AF. Or, the OAM provides the AF with the corresponding network energy consumption configuration information according to the request of the AF. The network energy consumption control information or network energy consumption configuration information may include the first energy-saving time period, energy-saving region, power-saving information of the network function (NF) serving the specified network slice or data network (for example: the second energy-saving time period or the energy-saving state during a specific time period, energy-saving service region), etc.

[0442] Step 5. Based on the analysis information for the terminal and / or application (service), as well as the network energy consumption related information or network energy consumption configuration information, AF determines the application (service) parameters related to energy saving, and / or the UE subscription information related to energy saving. The application (service) parameters related to energy saving may include: a specific application (service) is available for a specific UE within a specified time period and / or specified area, and / or, a specific application (service) is provided to a specific UE through a specified network slice or data network or access technology. The UE subscription information related to energy saving may include: the UE can use a specific application (service) within a specified time period and / or specified area, or use a specific application (service) through a specified network slice or data network.

[0443] Step 6. AF provides the application (service) parameters related to energy saving and / or the UE subscription information related to energy saving to the UDR (Unified Data Repository function) or UDM (Unified Data Management function) (through the NEF).

[0444] Step 7. The UDR or UDM notifies the PCF of the change in the application (service) parameters and / or the UE subscription information.

[0445] Step 8. Based on the updated application (service) parameters and / or the UE subscription information, the PCF determines (updates) the network energy saving policy for the terminal or application (service).

[0446] Step 9. Same as steps 6 - 13 in Embodiment 1. (That is: Step 6. The PCF provides the energy saving policy for the terminal or application (service) to the UE (through the AMF). For example: The UE or a specific application (service) preferentially uses a specified network slice, data network, access technology, and / or frequency within a specified energy saving time period and / or energy saving area.

[0447] Step 7. The UE performs energy saving operations according to the energy saving policy. For example, according to the URSP, when the UE is in the energy saving area during the energy saving period, the UE uses the PDU session in the specified network slice to transmit data of the specified application (service), including creating or modifying (existing) PDU sessions in the specified network slice to transmit data of the specified application (service).

[0448] Step 8. The PCF provides the energy saving policy to the AN. For example: a specific UE or application uses a specified network slice within a specified energy saving time period and energy saving area; or, within a specified energy saving time period and energy saving area, turn off the specified network slice 1 and use the specified network slice 2.

[0449] Step 9. The AN performs energy-saving operations according to the energy-saving policies provided by the PCF, and optionally, also according to local policies. For example: providing services to specific UEs or applications using specified network slices during specified energy-saving time periods and in specified energy-saving regions; or, turning off specified network slice 1 and using specified network slice 2 during specified energy-saving time periods and in specified energy-saving regions.

[0450] Step 10. The PCF provides the mobility management-related energy-saving policies to the AMF. For example: it includes a list of identifiers of UEs with high energy consumption, and optionally, also includes measurement, statistics, or prediction information on the energy consumed by the UEs, and may also include an indication to deregister UEs with high energy consumption.

[0451] Step 11. The AMF performs energy-saving operations according to the energy-saving policies provided by the PCF, and optionally, also according to local policies. For example: deregistering UEs with high energy consumption, or adjusting the mobility management parameters of the UEs (such as discontinuous transmission DTX parameters), or adjusting the UE-related parameters on the RAN side (such as discontinuous transmission DTX parameters) to reduce the energy consumption of the UEs on the network.

[0452] Step 12. The PCF provides the session management-related energy-saving policies to the SMF. For example: adjusting the QoS-related policies of applications with high energy consumption; it may also include a list of identifiers of UEs or applications with high energy consumption, and optionally, also includes measurement, statistics, or prediction information on the energy consumed by the UEs or applications ( / services), and an indication to release the PDU sessions of UEs with high energy consumption, etc.

[0453] Step 13. The SMF performs energy-saving operations according to the energy-saving policies provided by the PCF, and optionally, also according to local policies. For example: adjusting the QoS parameters of applications with high energy consumption according to the policies provided by the PCF, releasing the PDU sessions of UEs with high energy consumption, releasing the QoS flows (QoS flow) for applications with high energy consumption in transmission, etc.

[0454] Exemplarily, in Embodiment 3 (the UE provides information on UE mobility management-related capabilities and their effective conditions, and the AMF performs energy-saving operations based on UE mobility-related capabilities (including effective condition information), subscription data, network policies, network energy consumption control information, and / or mobility analysis information, etc., including performing energy-saving operations by itself, assisting other network functions (such as the access network AN, SMF, UPF), and the UE).

[0455] See Figure 4 as shown in Figure 4 the interaction diagram of the energy-saving method provided by the embodiments of this application Figure 3 The energy-saving method provided in this embodiment includes the following steps:

[0456] Step 0a. The UE sends a registration request message to the AMF, which carries information about the UE mobility management related capabilities and their effectiveness conditions, such as: LCS (location service) and the time and / or area information supporting the capability, paging subgroup and the time and / or area information supporting the capability, satellite communication and the time and / or area information supporting the capability.

[0457] Step 0b. After receiving the registration request message from the UE, the AMF requests the UDM for the UE's mobility management-related subscription data.

[0458] Step 0c. UDM provides AMF with the UE's mobility management-related subscription data, including the UE's subscribed mobility management capabilities ( / services) and their effectiveness conditions, such as: LCS and the time and / or area information supporting the UE to use LCS, paging subgroups and the time and / or area information supporting the UE to use paging subgroups, satellite communications and the time and / or area information supporting the UE to use satellite communications.

[0459] The AMF determines the network capabilities and their effectiveness conditions provided to the UE based on the UE's mobility management-related capabilities and their effectiveness conditions, mobility management-related contract data, network policies, network energy consumption control information and / or network data analysis information, such as: support for satellite communications and the time and / or regional information of network support for satellite communications, support for real-time ( / immersive) multimedia communications and the time and / or regional information of network support for this type of communication.

[0460] Step 0d.AMF sends a registration response message to the UE, which includes network capability information provided to the UE and its effectiveness condition information, such as satellite communication and the time and / or area information when the network supports satellite communication, real-time ( / immersive) multimedia communication and the time and / or area information when the network supports this type of communication.

[0461] Based on the network capability and its validity condition information in the registration response message, the UE activates the relevant capabilities only when the validity conditions are met, thereby achieving energy saving. For example: 1) Only at the specified time and / or area, the UE starts cell search in the frequency band corresponding to satellite access, uses satellite access technology to access the network and establish a session. 2) Only at the specified time and / or area, the UE initiates a real-time ( / immersive) multimedia communication request.

[0462] Step 1a.AMF requests NWDAF (including subscribing to multiple information or requesting information once, the same below) analysis information related to UE mobility.

[0463] Step 1b. The NWDAF provides the AMF with UE mobility-related analysis information (e.g., statistical or predicted UE geographical area distribution, UE location, UE movement trend, number of UEs in a specific cell, etc.).

[0464] Perform the following Steps 2 to 3a / 3b, or Steps 4a to 4b.

[0465] Step 2. Same as Steps 2a - 2c in Embodiment 1. (That is: Step 2a. The NEMF (Network Energy Management Function) requests network energy consumption-related analysis information from the NWDAF, such as resource usage prediction information for network slices or network functions (NFs).

[0466] Step 2b. The NWDAF provides the NEMF with network energy consumption-related analysis information.

[0467] Step 2c. The NEMF determines the network energy consumption control information, such as energy-saving time periods, corresponding energy-saving areas, working ( / non-working) network slices, and / or network functions, etc.).

[0468] Step 3a. The AMF requests the network energy consumption control information from the NEMF. The request message may include areas, time periods, network slice identifiers, NF information (e.g., NF identifiers, NF types, NF set identifiers, etc.).

[0469] Step 3b. Based on the request from the AMF, the NEMF provides the corresponding network energy consumption control information to the AMF.

[0470] Step 4a. The AMF requests access network and / or cell (AN / cell) energy consumption-related analysis information from the NWDAF.

[0471] Step 4b. The NWDAF provides the AMF with access network and / or cell energy consumption-related analysis information (e.g., predicted access network and / or cell energy consumption, energy efficiency, resource utilization rate, etc.).

[0472] Step 5. The AMF determines UE mobility-related energy-saving assistance information based on UE mobility-related capabilities (including activation condition information), subscription data, network policies, network energy consumption control information, and / or mobility analysis information, etc. The AMF provides the UE mobility-related energy-saving assistance information to the access network (AN).

[0473] Specifically, the AMF can determine one or more access network nodes that can perform energy-saving operations based on UE mobility-related information according to the network energy consumption control information obtained from the NEMF or the energy consumption-related analysis information of the access network and / or cell obtained from the NWDAF (for example, an access network node including one or more cells with a small number of served UEs), and provide the UE mobility-related information to these one or more access network nodes as energy-saving auxiliary information.

[0474] Step 6. The AN performs energy-saving operations according to the energy-saving auxiliary information provided by the AMF. For example:

[0475] Based on the energy-saving auxiliary information of a specific UE, for the specific UE:

[0476] 1) Use a specific paging strategy, such as a paging period, a paging area, etc., so as to reduce the energy consumption during the paging process; or,

[0477] 2) Use a specific transmission configuration for special signals (such as wake-up signals, synchronization signals), so as to reduce the energy consumption of signal transmission and related processing.

[0478] Based on the energy-saving auxiliary information of a specific cell:

[0479] 1) Shut down cells with a small number of UEs within a specific time period and / or a specific area; or,

[0480] 2) Select a cell with high energy efficiency ( / high resource utilization rate) as the target handover cell.

[0481] Step 7. The AN provides cell energy consumption-related information (such as information on cells with high energy efficiency or high resource utilization rate) to the UE for the UE to use for cell selection, cell reselection, or handover (such as conditional handover initiated by the UE).

[0482] Step 8. When the UE is within a specific time period and / or located ( / moves to) within a specific area, it selects, reselects, or hands over to a cell with high energy efficiency or high resource utilization rate. Thus, the RAN node can temporarily shut down cells with low energy efficiency or low resource utilization rate based on the number of UEs served by the cell, achieving the purpose of network energy saving.

[0483] Step 9. The AMF itself performs energy-saving operations related to UE mobility based on UE mobility-related capabilities (including activation condition information), subscription data, network policies, network energy consumption control information, and / or mobility analysis information, etc. For example: 1) Based on the UE's mobility management-related capabilities and their activation condition information, and mobility management-related subscription data, only enable satellite access-related functions (such as location verification) within specific time and / or specific areas. 2) If the number of UEs distributed within a specific time period and / or specific area is very small, reduce the service capacity of a specific service area (TA) (for example: reduce the server processing frequency in a specific area or reduce the allocated resources).

[0484] Step 10. The AMF provides UE mobility-related information (such as UE mobility-related capabilities (including activation condition information), mobility analysis information) to the SMF as energy-saving auxiliary information.

[0485] Step 11. The SMF performs energy-saving operations based on the energy-saving auxiliary information provided by the AMF. For example: 1) Based on the UE's mobility management-related capabilities and their activation conditions, and mobility analysis information, only enable satellite communication control functions (such as session processing related to satellite communication services) within specific time and / or specific areas; 2) If the number of UEs distributed within a specific time period and / or specific area is very small, reduce the service capacity of a specific service area (TA) (for example: reduce the server processing frequency in a specific area or reduce the allocated resources).

[0486] Step 12a / 12b. The AMF provides UE mobility-related information (such as UE mobility-related capabilities (including activation condition information), mobility analysis information) to the UPF as energy-saving auxiliary information. Or, the SMF provides UE mobility-related information to the UPF as energy-saving auxiliary information.

[0487] Step 13. The UPF performs energy-saving operations based on the energy-saving auxiliary information provided by the AMF or SMF. For example: 1) Based on the UE's mobility management-related capabilities and their activation conditions, and mobility analysis information, only enable satellite communication user plane functions (such as packet processing related to satellite communication services) within specific time and / or specific areas; 2) If the number of UEs distributed within a specific time period and / or specific area is very small, reduce the service capacity of a specific service area (TA) (for example: reduce the server processing frequency in a specific area or reduce the allocated resources).

[0488] Exemplarily, in Embodiment 4 (the UE provides UE session management related capabilities and their activation condition information, and the SMF performs energy saving operations based on the UE session management related capabilities (including activation condition information), subscribed data, network policies, network energy consumption control information, and / or UE communication (i.e., session management) analysis information, etc., including performing energy saving operations on itself, assisting other network functions (such as the access network AN, UPF), and the UE)

[0489] See Figure 5 as shown Figure 5 is an interaction diagram of the energy saving method provided by the embodiments of the present application Figure 4 The energy saving method provided in this embodiment includes the following steps:

[0490] Step 0a. The UE sends a session request message (such as a session establishment request, session modification request, or session release request) to the SMF, which carries UE session management related capabilities and their activation condition information, such as: real-time ( / immersive) multimedia communication capabilities and the time and / or area information supporting such capabilities, satellite communication and the time and / or area information using satellite communication, multicast and / or broadcast communication and the time and / or area information using multicast and / or broadcast communication.

[0491] Step 0b. After receiving the session request message from the UE, the SMF requests the UE's session management related subscribed data from the UDM.

[0492] Step 0c. The UDM provides the SMF with the UE's session management related subscribed data, which contains the UE's subscribed session management capabilities ( / services) and their activation condition information, such as: real-time ( / immersive) multimedia communication and the time and / or area information using such communication capabilities ( / services), satellite communication and the time and / or area information using satellite communication, multicast and / or broadcast communication and the time and / or area information using multicast and / or broadcast communication.

[0493] Based on the UE's session management related capabilities and their activation condition information carried in the session request message, the session management related subscribed data included in the UE's subscription information, network policies, network energy consumption control information, and / or network data analysis information, etc., the SMF determines the session management related network capabilities and their activation condition information provided to the UE, such as: real-time ( / immersive) multimedia communication and the time and / or area information supported by the network for this type of communication, satellite communication and the time and / or area information supported by the network for satellite communication, multicast and / or broadcast communication and the time and / or area information supported by the network for multicast and / or broadcast communication.

[0494] Step 0d. The SMF sends a session response to the UE, which includes network capability information related to session management provided to the UE and its activation condition information, such as: real-time ( / immersive) multimedia communication and the time and / or area information of the network supporting this type of communication, satellite communication and the time and / or area information of the network supporting satellite communication, multicast and / or broadcast communication and the time and / or area information of the network supporting multicast and / or broadcast communication.

[0495] The UE activates the relevant capabilities only when the activation conditions are met based on the network capabilities and their activation condition information in the session response message, so as to achieve the purpose of energy saving. For example: only within the specified time and / or area, the UE initiates requests for real-time ( / immersive) multimedia communication, satellite communication or multicast / broadcast communication.

[0496] Step 1a. The SMF requests analysis information related to UE communication (i.e., session management) from the NWDAF.

[0497] Step 1b. The NWDAF provides the SMF with analysis information related to UE communication, including the communication time of the UE (communication cycle, start time, duration, etc.), data traffic characteristics (such as network slice identifier S-NSSAI, data network name DNN, IP address, port number, etc.), uplink and downlink data traffic, and / or application ( / service) characteristics (such as application identifier, start time, duration); uplink and downlink data traffic of all UEs in a specific cell, etc.).

[0498] Perform the following steps 2~3a / 3b, or steps 4a~4b.

[0499] Step 2. Same as steps 2a-2c in Embodiment 1. (That is: Step 2a. The NEMF (Network Energy Management Function) requests analysis information related to network energy consumption from the NWDAF, such as resource usage prediction information of network slices or network functions (NFs).

[0500] Step 2b. The NWDAF provides the NEMF with analysis information related to network energy consumption.

[0501] Step 2c. The NEMF determines the energy consumption control information of the network, such as the energy-saving time period, the corresponding energy-saving area, working ( / non-working) network slices and / or network functions, etc.).

[0502] Step 3a. The SMF requests the energy consumption control information of the network from the NEMF. The request message may include the area, time period, network slice identifier, NF information (such as NF identifier, NF type, NF set identifier, etc.).

[0503] Step 3b. The NEMF provides corresponding network energy consumption control information to the SMF according to the request of the SMF.

[0504] Step 4a. The SMF requests energy consumption related analysis information of the access network and / or cell (AN / cell) from the NWDAF.

[0505] Step 4b. The NWDAF provides the SMF with energy consumption related analysis information of the access network and / or cell (such as predicted energy consumption, energy efficiency, resource utilization rate, etc. of the access network and / or cell).

[0506] Step 5. The SMF determines energy-saving assistance information related to UE session management based on UE session management related capabilities (including activation condition information), subscribed data, network policies, network energy consumption control information, and / or analysis information of UE communication, etc. The SMF provides the energy-saving assistance information related to UE session management to the access network (AN).

[0507] Specifically, the SMF can determine one or more access network nodes that can perform energy-saving operations based on UE session management related information (such as UE session management related capabilities (including activation condition information), UE communication analysis information) according to the network energy consumption control information obtained from the NEMF or the energy consumption related analysis information of the access network and / or cell obtained from the NWDAF, and provide the UE session management related information to these one or more access network nodes as energy-saving assistance information.

[0508] Step 6. The AN performs energy-saving operations according to the energy-saving assistance information provided by the SMF, such as:

[0509] Based on the energy-saving assistance information of a specific UE, for the specific UE:

[0510] 1) Provide resources for specific communication only within a specified time or area, such as only support paging processes related to real-time ( / immersive) multimedia communication, satellite communication, or multicast / broadcast communication within a specified time or area, and / or establish relevant signaling and / or data bearers.

[0511] Based on the energy-saving assistance information of a specific cell:

[0512] 1) Turn off cells with low uplink and downlink data traffic within a specific time period and / or specific area; or,

[0513] 2) Select a cell with high energy efficiency ( / high resource utilization rate) as the target handover cell.

[0514] Step 7. The AN provides cell energy consumption related information (such as information of cells with high energy efficiency or high resource utilization rate) to the UE for the UE to use for cell selection, cell reselection, or handover (such as conditional handover initiated by the UE).

[0515] Step 8. When the UE is within a specific time period and / or located (moves to) within a specific area, it selects, reselects, or switches to a cell with high energy efficiency or high resource utilization rate. As a result, the RAN node can temporarily turn off cells with low energy efficiency or low resource utilization rate based on the number of UEs served by the cell, achieving the purpose of network energy saving.

[0516] Step 9. The SMF itself performs energy-saving operations related to UE session management based on UE session management-related capabilities (including activation condition information), subscribed data, network policies, network energy consumption control information, and / or UE communication analysis information, etc. For example: 1) According to the UE's session management-related capabilities and their activation conditions, communication analysis information, enable the control functions of real-time (immersive) multimedia communication, satellite communication, or multicast / broadcast communication only within a specific time and / or specific area, such as session management related to real-time (immersive) multimedia communication, satellite communication, or multicast / broadcast communication; 2) If the uplink and downlink data traffic of all UEs within a specific time period and / or specific area is low, reduce the service capabilities of a specific service area (TA) (for example: reduce the server processing frequency of a specific area or reduce the allocated resources).

[0517] Step 10. The SMF provides energy-saving related session control information (such as releasing a session or modifying QoS parameters) to the UPF, or provides UE session management-related information (such as UE session management-related capabilities (including activation condition information), UE communication analysis information) to the UPF as energy-saving auxiliary information.

[0518] Step 11. The UPF performs energy-saving operations based on the energy-saving related session control information or energy-saving auxiliary information provided by the SMF. For example: 1) According to the UE's session management-related capabilities and their activation conditions, UE communication analysis information, enable the user plane functions of real-time (immersive) multimedia communication, satellite communication, or multicast / broadcast communication only within a specific time and / or specific area, such as packet processing related to real-time (immersive) multimedia communication, satellite communication, or multicast / broadcast communication services; 2) Reduce the service capabilities of a specific service area (TA) within a specific time period and / or specific area (for example: reduce the server processing frequency of a specific area or reduce the allocated resources).

[0519] Exemplarily, in Embodiment 5 (the AMF and SMF perform energy-saving operations based on UE abnormal behavior analysis information, etc., including performing energy-saving operations by themselves and assisting other network functions (such as the access network AN, UPF))

[0536] Step 6. The SMF sends the analysis information of the UE's communication abnormal behavior to the AMF.

[0537] Step 7. The AMF provides the analysis information of the UE's movement and / or communication abnormal behavior to the access network (AN) as energy - saving auxiliary information. Specifically, the AMF can obtain the energy consumption information of the access network and / or cell based on Step 4, and accordingly determine one or more access network nodes that can perform energy - saving operations based on the UE abnormal behavior - related information, and provide the UE abnormal behavior - related information to these one or more access network nodes as energy - saving auxiliary information.

[0538] Step 8. The AN performs energy - saving operations according to the energy - saving auxiliary information provided by the AMF, such as: releasing the connection with the abnormal UE, or restricting the access of the abnormal UE, or restricting the uplink / downlink data volume of the abnormal UE.

[0539] Step 9. The AMF itself performs energy - saving operations according to the analysis information of the UE's movement and / or communication abnormal behavior, such as: initiating the deregistration of the abnormal UE.

[0597] Optionally, the energy-saving policy or the energy-saving assistance information is carried in a first message; the first message is a registration request message or a service request message, and the first communication capability and the first effective condition information are carried in the registration request message or the service request message, where the first communication capability is the mobility management-related capability of the terminal; or,

[0598] The first message is a session request message, and the first communication capability and the first effective condition information are carried in the session request message, where the first communication capability is the session management-related capability of the terminal.

[0599] In the embodiments of this application, as shown in Figure 4 , the UE sends a registration request message to the AMF, which carries the UE mobility management-related capability and its effective condition information, for example: LCS (Location Service) and the time and / or area information supporting this capability, paging subgroup and the time and / or area information supporting this capability, satellite communication and the time and / or area information supporting this capability.

[0600] After the AMF receives the registration request message of the UE, it requests the mobility management related subscription data of the UE from the UDM.

[0601] The UDM provides the AMF with the mobility management related subscription data of the UE, which includes the mobility management capabilities ( / services) subscribed by the UE and the information on their effective conditions, such as: LCS and the time and / or area information supporting the UE to use LCS, paging subgroup and the time and / or area information supporting the UE to use the paging subgroup, satellite communication and the time and / or area information supporting the UE to use satellite communication.

[0602] Based on the mobility management related capabilities of the UE and the information on their effective conditions, the mobility management related subscription data, network policies, network energy consumption control information and / or network data analysis information, etc., the AMF determines the network capabilities provided to the UE and the information on their effective conditions, such as: satellite communication and the time and / or area information supported by the network for satellite communication, real-time ( / immersive) multimedia communication and the time and / or area information supported by the network for this type of communication.

[0603] The AMF sends a registration response message to the UE, which includes the network capabilities provided to the UE and the information on their effective conditions, such as: satellite communication and the time and / or area information supported by the network for satellite communication, real-time ( / immersive) multimedia communication and the time and / or area information supported by the network for this type of communication.

[0604] The terminal can start the relevant capabilities only when the effective conditions are met according to the network capabilities (here referring to the network capability information) and the information on their effective conditions in the registration response message, so as to achieve the purpose of energy saving. For example: 1) Only within the specified time and / or area, the UE starts cell search in the frequency band corresponding to satellite access, uses satellite access technology to access the network and establish a session. 2) Only within the specified time and / or area, the UE initiates a real-time ( / immersive) multimedia communication request.

[0605] Combined Figure 5 As shown, the UE sends a session request message (such as a session establishment request, a session modification request or a session release request) to the SMF, which carries the UE session management related capabilities and the information on their effective conditions, such as: real-time ( / immersive) multimedia communication capabilities and the time and / or area information supporting this capability, satellite communication and the time and / or area information using satellite communication, multicast and / or broadcast communication and the time and / or area information using multicast and / or broadcast communication.

[0606] After the SMF receives the session request message of the UE, it requests the session management related subscription data of the UE from the UDM.

[0607] The UDM provides the SMF with the subscription data related to the session management of the UE, which includes the session management capabilities ( / services) subscribed by the UE and the information about their activation conditions, such as: real-time ( / immersive) multimedia communication and the time and / or area information for using this communication capability ( / service), satellite communication and the time and / or area information for using satellite communication, multicast and / or broadcast communication and the time and / or area information for using multicast and / or broadcast communication.

[0608] The SMF determines the network capabilities related to the session management provided to the UE and the information about their activation conditions based on the session management related capabilities of the UE carried in the session request message and the information about their activation conditions, the subscription data related to the session management included in the UE's subscription information, network policies, network energy consumption control information, and / or network data analysis information, etc., such as: real-time ( / immersive) multimedia communication and the time and / or area information for which the network supports this type of communication, satellite communication and the time and / or area information for which the network supports satellite communication, multicast and / or broadcast communication and the time and / or area information for which the network supports multicast and / or broadcast communication.

[0609] The SMF sends a session response to the UE, which includes the network capabilities related to the session management provided to the UE and the information about their activation conditions, such as: real-time ( / immersive) multimedia communication and the time and / or area information for which the network supports this type of communication, satellite communication and the time and / or area information for which the network supports satellite communication, multicast and / or broadcast communication and the time and / or area information for which the network supports multicast and / or broadcast communication.

[0610] The terminal can start the relevant capabilities only when the activation conditions are met based on the network capabilities (here referring to the network capability information) and the information about their activation conditions in the session response message, so as to achieve the purpose of energy saving. For example: only within the specified time and / or area, the UE initiates requests for real-time ( / immersive) multimedia communication, satellite communication, or multicast / broadcast communication.

[0611] Specifically, the UE provides the network with the capabilities related to UE mobility management and the information about their activation conditions, and / or, the capabilities related to UE session management and the information about their activation conditions; and receives the network capabilities and the information about their activation conditions from the network. The UE enables the relevant functions according to the activation conditions, such as performing the relevant mobility management or session management processes only at specific times or in specific areas.

[0612] Therefore, in this application, the solution for enhancing processes such as policy control, mobility management, and session management in the mobile communication network based on the information in the network (such as network data analysis information, including statistical and predictive information about terminals, applications, and network communication behaviors, etc.; subscription data) is beneficial to further reducing network energy consumption and improving network energy-saving performance.

[0613] It should be noted here that for the energy-saving method with the terminal as the execution entity provided by this application, the specific implementation process can refer to Figures 2 - 6 the illustrated embodiment, and the specific implementation process will not be elaborated here.
