[0148] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0149] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0150] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0151] In order to clearly understand the technical solution of this application, the solution of the related technology is first introduced in detail.

[0152] A communication system is composed of a variety of communication devices, which consume energy (such as electricity) when providing communication services. The energy consumption of the entire communication system is the sum of the energy consumption of all communication devices in the system. The energy consumption of communication equipment refers to the energy consumed by communication equipment to support communication operations and complete communication tasks. Energy consumption can be calculated by measuring the power of the equipment over a period of time. The energy efficiency of a communication system / communication equipment reflects the efficiency of energy consumption, that is, the ratio of providing a certain communication service to the energy consumed. For example, it can be defined as the ratio of the amount of data transmitted to energy consumption, or the ratio of the communication area covered ( / service) to energy consumption. Energy efficiency can be measured for the entire network, subnet (such as a wireless access network), a single network device, a communication site (such as a data center), a terminal, etc.

[0153] However, in order to support the functions and performance of mobile communications, current mobile communication networks and devices have high energy consumption, resulting in low energy efficiency.

[0154] To solve the problem of high energy consumption of mobile communication networks and equipment in related technologies, which leads to low energy efficiency, we can effectively utilize information in the network, such as network energy-saving strategies or energy-saving auxiliary information, to optimize and enhance existing communication processes or network processes, thereby further reducing the energy consumption of communication systems and communication equipment and improving energy efficiency.

[0155] Therefore, based on the above research, the energy-saving method and device proposed in this application are proposed. In this application, based on the information in the network (such as network data analysis information, including statistical and predictive information on terminals, applications and network communication behaviors; contract data), a solution is proposed to enhance the processes such as policy control, mobility management and session management in the mobile communication network, so as to achieve the purpose of reducing network energy consumption and improving network energy-saving performance.

[0250] Step 3. PCF requests network energy consumption control information from NEMF. The request message may include the region, time period, network slice identifier, and NF information (e.g., NF identifier, NF type, NF set identifier, etc.).

[0251] Step 4. NEMF provides the corresponding network energy consumption control information to PCF based on the request of PCF.

[0252] Step 5. The PCF determines a network energy-saving strategy for the terminal or application (or service) based on the analysis information for the terminal and / or application (or service) and the network energy consumption control information.

[0253] Step 6. The PCF provides the energy-saving policy for the terminal or application (or service) to the UE (via the AMF). For example, the UE or a specific application (or service) may prioritize the use of a specific network slice, data network, access technology, and / or frequency in a specified energy-saving time period and / or energy-saving area.

[0254] 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).

[0255] Step 8. The PCF provides the energy-saving policy to the AN. For example, a specific UE or application may use a specific network slice in a specified energy-saving period and area; or, in a specified energy-saving period and area, disable a specified network slice 1 and use a specified network slice 2.

[0256] Step 9. AN performs energy-saving operations based on the energy-saving strategy provided by PCF and, in some embodiments, local strategies, such as providing services to specific UEs or applications using a specified network slice in a specified energy-saving time period and energy-saving area; or, shutting down a specified network slice 1 and using a specified network slice 2 in a specified energy-saving time period and energy-saving area.

The AF provides the energy-saving related application ( / service) parameters and / or energy-saving related UE subscription information to the UDM / UDR and PCF. The PCF determines a (network) energy-saving policy for the terminal or application ( / service) based on this, and provides the energy-saving policy to the UE, AN ( / AMF, and SMF.)

[0262] Referring to FIG3 , FIG3 is a second interactive diagram of the energy-saving method provided in an embodiment of the present application. The energy-saving method provided in this embodiment includes the following steps:

[0263] Step 1. The AF requests the NWDAF for analysis information of terminals and / or applications ( / services), such as analysis information of discrete distribution of terminals and / or applications ( / services) in time and area.

[0264] Step 2. NWDAF provides AF with analysis information of the terminal and / or application ( / service).

[0265] Step 3. The AF requests network energy consumption-related information from the NEMF (or NEF), or requests network energy consumption configuration information from the OAM. The request message may include information such as the region, time period, network slice identifier (e.g., one or more single network slice selection assistance information S-NSSAI(s)), and data network name (DNN).

[0266] Step 4. The NEMF (or NEF) provides the AF with corresponding network energy consumption related information based on the AF's request.

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

[0268] Step 6. The AF (through the NEF) provides energy-saving related application ( / service) parameters and / or UE subscription information to the UDR (Unified Database Function) or UDM (Unified Data Management Function).

[0269] Step 7. The UDR or UDM notifies the PCF of changes in application ( / service) parameters and / or UE subscription information.

[0270] Step 8. The PCF determines (or updates) a network energy saving strategy for the terminal or application (or service) based on the updated application (or service) parameters and / or UE subscription information.

[0271] Step 9. Same as steps 6-13 in Example 1. (i.e., Step 6. The PCF provides the energy-saving policy for the terminal or application ( / service) to the UE (via the AMF). For example, the UE or a specific application ( / service) preferentially uses a specified network slice, data network, access technology, and / or frequency in a specified energy-saving time period and / or energy-saving area.

[0272] 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).

[0273] Step 8. The PCF provides the energy-saving policy to the AN. For example, a specific UE or application may use a specific network slice in a specified energy-saving period and area; or, in a specified energy-saving period and area, disable a specified network slice 1 and use a specified network slice 2.

[0274] Step 9. AN performs energy-saving operations based on the energy-saving strategy provided by PCF and, in some embodiments, local strategies, such as providing services to specific UEs or applications using a specified network slice in a specified energy-saving time period and energy-saving area; or, shutting down a specified network slice 1 and using a specified network slice 2 in a specified energy-saving time period and energy-saving area.

[0275] Step 10.

[0276] Step 11. The AMF performs energy-saving operations based on the energy-saving strategy provided by the PCF and, in some embodiments, local strategies, such as deregistering UEs with higher energy consumption, or adjusting the UE's mobility management parameters (e.g., discontinuous transmission (DTX) parameters), or adjusting RAN-side UE-related parameters (e.g., discontinuous transmission (DTX) parameters) to reduce the UE's consumption of network energy.

[0277] Step 12. PCF provides the session management related energy-saving strategy to SMF, for example: adjusting the QoS related strategy of the application with higher energy consumption; it may also include a list of UE identifiers or application identifiers with higher energy consumption. In some embodiments, it also includes measurement, statistics or prediction information of the energy consumed by the UE or application ( / service), as well as an indication of releasing the PDU session of the UEs with higher energy consumption, etc.

[0278] Step 13. The SMF performs energy-saving operations based on the energy-saving policy provided by the PCF and, in some embodiments, local policies. For example, the SMF adjusts QoS parameters for energy-intensive applications based on the policy provided by the PCF, releases PDU sessions for energy-intensive UEs, and releases QoS flows for energy-intensive applications.

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 that supports the capability, paging subgroup and the time and / or area information that supports the capability, satellite communication and the time and / or area information that supports the capability.

[0282] Step 0b. After receiving the registration request message from the UE, the AMF requests the UE's mobility management-related subscription data from the UDM.

[0283] Step 0c. The UDM provides the AMF with the UE's mobility management-related subscription data, which includes 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 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.

[0284] 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 subscription data, network policies, network energy consumption control information and / or network data analysis information, such as: support for satellite communication and the time and / or regional information of the network supporting satellite communication, support for real-time ( / immersive) multimedia communication and the time and / or regional information of the network supporting this type of communication.

[0285] Step 0d. The AMF sends a registration response message to the UE, which contains the network capability information provided to the UE and its effectiveness conditions, such as satellite communication and the time and / or area information of the network supporting satellite communication, real-time ( / immersive) multimedia communication and the time and / or area information of the network supporting this type of communication.

[0286] Based on the network capabilities and their activation conditions in the registration response message, the UE activates the relevant capabilities only when the activation conditions are met, thereby achieving energy conservation. For example: 1) Only within a specified time and / or area, the UE initiates a cell search in the frequency band corresponding to satellite access, accesses the network using satellite access technology, and establishes a session. 2) Only within a specified time and / or area, the UE initiates a real-time (or immersive) multimedia communication request.

[0287] Step 1a.AMF requests (including subscribing to multiple information or requesting information once, the same below) UE mobility-related analysis information from NWDAF.

[0288] Step 1b. The NWDAF provides the AMF with analysis information related to UE mobility (e.g. statistical or predicted UE geographical distribution, UE location, UE mobility trend, number of UEs in a specific cell, etc.).

[0289] Perform steps 2 to 3a / 3b below, or steps 4a to 4b.

[0290] Step 2. Same as steps 2a-2c of embodiment 1. (i.e., step 2a. NEMF (Network Energy Management Function) requests network energy consumption-related analysis information from NWDAF, such as resource usage prediction information of network slices or network functions (NFs).

[0291] Step 2b. NWDAF provides NEMF with analysis information related to network energy consumption.

[0292] Step 2c. NEMF determines the energy consumption control information of the network, such as energy-saving time period, corresponding energy-saving area, active (or non-active) network slices and / or network functions, etc.

[0293] Step 3a. The AMF requests the NEMF for network energy consumption control information. The request message may include the region, time period, network slice identifier, and NF information (e.g., NF identifier, NF type, NF set identifier, etc.).

[0294] Step 3b. NEMF provides AMF with the corresponding network energy consumption control information based on AMF's request.

[0295] Step 4a.AMF requests NWDAF for energy consumption related analysis information of the access network and / or cell (AN / cell).

[0296] Step 4b. NWDAF provides AMF with energy consumption-related analysis information of the access network and / or cell (for example, predicted energy consumption, energy efficiency, resource utilization, etc. of the access network and / or cell).

[0297] Step 5. The AMF determines UE mobility-related energy-saving assistance information based on UE mobility-related capabilities (including validity condition information), subscription data, network policies, network energy consumption control information, and / or mobility analysis information. The AMF provides the UE mobility-related energy-saving assistance information to the access network (AN).

[0298] The AMF can determine one or more access network nodes (for example, an access network node including one or more cells serving a small number of UEs) that can perform energy-saving operations based on UE mobility-related information based on 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 mobility-related information to the one or more access network nodes as energy-saving auxiliary information.

[0299] Step 6. AN performs energy-saving operations based on the energy-saving assistance information provided by AMF, for example:

[0300] Based on the energy-saving assistance information of a specific UE, for a specific UE:

[0301] 1) Use specific paging strategies, such as paging time periods, paging areas, etc., to reduce the energy consumption of the paging process; or,

[0302] 2) Use specific transmission configurations for special signals (such as wake-up signals and synchronization signals) to reduce the energy consumption of signal transmission and related processing.

[0303] Energy-saving assistance information based on specific cells:

[0304] 1) Shutting down cells with a small number of UEs within a specific time period and / or specific area; or

[0305] 2) Select a cell with high energy efficiency ( / high resource utilization) as the target handover cell.

[0306] Step 7. The AN provides the cell energy consumption related information (such as information of cells with high energy efficiency or high resource utilization) to the UE for use in cell selection, cell reselection or handover (such as conditional handover initiated by the UE).

[0307] Step 8. The UE selects, reselects, or switches to a cell with high energy efficiency or high resource utilization during a specific time period and / or when located within (or moving into) a specific area. This allows the RAN node to temporarily shut down cells with low energy efficiency or low resource utilization based on the number of UEs served by the cell, thereby achieving network energy conservation.

[0308] Step 9. The AMF performs UE mobility-related energy-saving operations based on the UE's mobility-related capabilities (including activation conditions), subscription data, network policies, network energy consumption control information, and / or mobility analysis information. For example: 1) Based on the UE's mobility management-related capabilities and their activation conditions, and mobility management-related subscription data, only enable satellite access-related functions (e.g., location verification) during specific times and / or within specific areas. 2) If the number of UEs distributed in a specific time period and / or specific area is small, reduce the service capacity of a specific service area (TA) (e.g., reduce the server processing frequency or reduce the allocated resources in a specific area).

[0309] Step 10.AMF provides UE mobility related information (such as UE mobility related capabilities (including validity condition information) and mobility analysis information) to SMF as energy-saving auxiliary information.

[0310] Step 11. SMF performs energy-saving operations based on the energy-saving assistance information provided by AMF, for example: 1) based on the UE's mobility management-related capabilities and its effectiveness conditions, and mobility analysis information, only enables satellite communication control functions (such as session processing related to satellite communication services) at specific times and / or in specific areas; 2) if the number of UEs distributed in a specific time period and / or a specific area is small, the service capacity of the specific service area (TA) is reduced (for example: reducing the server processing frequency in a specific area or reducing the allocated resources).

[0311] Step 12a / 12b. The AMF provides the UE mobility-related information (e.g., UE mobility-related capabilities (including validity condition information) and mobility analysis information) to the UPF as energy-saving assistance information. Alternatively, the SMF provides the UE mobility-related information to the UPF as energy-saving assistance information.

[0312] Step 13. UPF performs energy-saving operations based on the energy-saving assistance information provided by AMF or SMF, for example: 1) based on the UE's mobility management-related capabilities and its effectiveness conditions, and mobility analysis information, satellite communication user plane functions (such as data packet processing related to satellite communication services) are only enabled at specific times and / or in specific areas; 2) if the number of UEs distributed in a specific time period and / or a specific area is small, the service capability of a specific service area (TA) is reduced (for example: reducing the server processing frequency in a specific area or reducing the allocated resources).

[0313] Exemplarily, embodiment four (UE provides UE session management related capabilities and their effectiveness condition information, SMF performs energy-saving operations based on UE session management related capabilities (including effectiveness condition information), contract data, network policies, network energy consumption control information and / or UE communication (ie, session management) analysis information, including itself, assisting other network functions (such as access network AN, UPF) and UE to perform energy-saving operations).

[0314] Referring to FIG5 , FIG5 is a fourth interactive diagram of the energy-saving method provided in an embodiment of the present application. The energy-saving method provided in this embodiment includes the following steps:

[0315] Step 0a. The UE sends a session request message (e.g., a session establishment request, a session modification request, or a session release request) to the SMF, which carries information about the UE session management related capabilities and their effectiveness conditions, such as: real-time ( / immersive) multimedia communication capabilities and the time and / or area information for supporting the capabilities, 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.

[0316] Step 0b. After receiving the session request message from the UE, the SMF requests the UE's session management-related subscription data from the UDM.

[0317] Step 0c. UDM provides the SMF with the UE's session management-related subscription data, which includes the UE's subscribed session management capabilities ( / services) and their effectiveness conditions, such as real-time ( / immersive) multimedia communication and the time and / or area information for using the 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.

[0318] The SMF determines the network capabilities related to session management and their effectiveness conditions provided to the UE based on the UE's session management related capabilities and their effectiveness conditions carried in the session request message, the session management related subscription data contained 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 regional information of the network supporting this type of communication, satellite communication and the time and / or regional information of the network supporting satellite communication, multicast and / or broadcast communication and the time and / or regional information of the network supporting multicast and / or broadcast communication.

[0319] Step 0d.SMF sends a session response to the UE, which includes network capability information related to session management provided to the UE and its effectiveness 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.

[0320] Based on the network capabilities and their activation conditions in the session response message, the UE activates the relevant capabilities only when the activation conditions are met, thereby achieving energy conservation. For example, the UE may initiate requests for real-time (or immersive) multimedia communication, satellite communication, or multicast / broadcast communication only within a specified time and / or area.

[0321] Step 1a. SMF requests analysis information related to UE communication (i.e. session management) from NWDAF.

[0322] Step 1b. NWDAF provides SMF with analysis information related to UE communication, including UE communication time (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.).

[0323] Perform steps 2 to 3a / 3b below, or steps 4a to 4b.

[0325] Step 2b. NWDAF provides NEMF with analysis information related to network energy consumption.

[0326] Step 2c. NEMF determines the energy consumption control information of the network, such as energy-saving time period, corresponding energy-saving area, active (or non-active) network slices and / or network functions, etc.

[0327] Step 3a. SMF requests network energy consumption control information from NEMF. The request message may include the region, time period, network slice identifier, and NF information (e.g., NF identifier, NF type, NF set identifier, etc.).

The SMF provides the energy-saving assistance information related to UE session management to the access network (AN).

[0332] 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 effectiveness condition information), UE communication analysis information) based on the network energy consumption control information obtained from NEMF, or the energy consumption-related analysis information of the access network and / or cell obtained from NWDAF, and provide UE session management related information to these one or more access network nodes as energy-saving auxiliary information.

[0333] Step 6. AN performs energy-saving operations based on the energy-saving auxiliary information provided by SMF, for example:

[0339] Step 7. The AN provides the cell energy consumption related information (such as information of cells with high energy efficiency or high resource utilization) to the UE for use in cell selection, cell reselection or handover (such as conditional handover initiated by the UE).

[0340] Step 8. The UE selects, reselects, or switches to a cell with high energy efficiency or high resource utilization during a specific time period and / or when located within (or moving into) a specific area. This allows the RAN node to temporarily shut down cells with low energy efficiency or low resource utilization based on the number of UEs served by the cell, thereby achieving network energy conservation.

[0341] Step 9. The SMF itself performs energy-saving operations related to UE session management based on UE session management-related capabilities (including effectiveness condition information), subscription data, network policies, network energy consumption control information and / or UE communication analysis information, for example: 1) Based on the UE's session management-related capabilities and its effectiveness conditions, communication analysis information, only enable real-time ( / immersive) multimedia communication, satellite communication or multicast / broadcast communication control functions at specific times and / or in specific areas, such as real-time ( / immersive) multimedia communication, satellite communication or multicast / broadcast communication-related session management; 2) If the uplink and downlink data traffic of (all) UEs in a specific time period and / or a specific area is small, reduce the service capacity of the specific service area (TA) (for example: reduce the server processing frequency in a specific area or reduce the allocated resources).

[0342] Step 10. SMF provides energy-saving related session control information (such as releasing the session or modifying QoS parameters) to UPF, or provides UE session management related information (such as UE session management related capabilities (including effectiveness condition information), UE communication analysis information) to UPF as energy-saving auxiliary information.

[0427] The UDM provides the 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 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.

[0428] 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 subscription data, network policies, network energy consumption control information and / or network data analysis information, such as satellite communication and the time and / or regional information of the network supporting satellite communication, real-time ( / immersive) multimedia communication and the time and / or regional information of the network supporting this type of communication.

[0429] The 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 time and / or area information of network support for satellite communication, real-time ( / immersive) multimedia communication and time and / or area information of network support for this type of communication.

[0430] Based on the network capabilities (herein, network capability information) and their activation conditions in the registration response message, the terminal can activate the relevant capabilities only when the activation conditions are met, thereby achieving energy conservation. For example: 1) Only within a specified time and / or area, the UE initiates a cell search in the frequency band corresponding to satellite access, uses satellite access technology to access the network, and establishes a session. 2) Only within a specified time and / or area, the UE initiates a real-time (or immersive) multimedia communication request.

[0431] As shown in Figure 5, 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 UE session management related capabilities and their effectiveness condition information, such as: real-time ( / immersive) multimedia communication capabilities and time and / or area information for supporting the capability, satellite communication and time and / or area information for using satellite communication, multicast and / or broadcast communication and time and / or area information for using multicast and / or broadcast communication.

[0432] After receiving the session request message from the UE, the SMF requests the UE's session management-related subscription data from the UDM.

[0433] UDM provides SMF with UE's session management-related subscription data, which includes the UE's subscribed session management capabilities ( / services) and their effectiveness conditions, such as real-time ( / immersive) multimedia communication and the time and / or area information of using the communication capability ( / service), satellite communication and the time and / or area information of using satellite communication, multicast and / or broadcast communication and the time and / or area information of using multicast and / or broadcast communication.

[0434] The SMF determines the network capabilities related to session management and their effectiveness conditions provided to the UE based on the UE's session management related capabilities and their effectiveness conditions carried in the session request message, the session management related subscription data contained 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 regional information of the network supporting this type of communication, satellite communication and the time and / or regional information of the network supporting satellite communication, multicast and / or broadcast communication and the time and / or regional information of the network supporting multicast and / or broadcast communication.

[0435] The SMF sends a session response to the UE, which includes network capability information related to session management provided to the UE and its effectiveness 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.

[0436] The terminal can activate the relevant capabilities only when the conditions are met based on the network capabilities (here, network capability information) and their activation conditions in the session response message, thereby achieving energy conservation. For example, the UE may initiate requests for real-time (or immersive) multimedia communication, satellite communication, or multicast / broadcast communication only within a specified time and / or area.

[0437] The UE provides the network with information about its mobility management capabilities and their enabling conditions, and / or UE session management capabilities and their enabling conditions; and receives information about its network capabilities and their enabling conditions from the network. The UE enables related functions based on the enabling conditions, for example, executing related mobility management or session management processes only within a specific time or area.

[0438] Therefore, in this application, based on information in the network (such as network data analysis information, including statistical and predictive information on terminals, applications and network communication behaviors; contract data), a solution for enhancing processes such as policy control, mobility management and session management in mobile communication networks is beneficial to further reduce network energy consumption and improve network energy-saving performance.
