[0003] The present disclosure relates to the field of communication technologies, and in particular to a communication method, device, and storage medium. Background Art

[0004] The fifth generation mobile communication (5G) network can instruct the terminal / user equipment (UE) to select which access technology or technologies to transmit application / service data by sending policies or rules (e.g., UE Routing Selection Policy (URSP), Access Traffic Steering Switching Splitting (ATSSS) rules) for transmitting application / service data on a (single access) protocol data unit (PDU) session and / or a multi-access PDU session.

[0409] The wireless mobile communication system can support UE to establish multi-access connections with the network through multiple different access technologies (ATs), and use these ATs to establish (single access) PDU sessions or multi-access PDU sessions.

[0410] Access technologies (AT) include: terrestrial 3GPP access technologies (such as NR, E-UTRA, UTRA, NR RedCap), satellite (non-terrestrial) 3GPP access technologies (such as NR (LEO), NR (MEO), NR (GEO), NR (OTHERSAT)); non-3GPP access technologies (such as trusted WLAN access, untrusted WLAN access, etc.).

[0411] A (single access) PDU session refers to a PDU session that uses only one AT to transmit data; a multi-access PDU session has access branches established on different ATs and can use different ATs to transmit data.

[0412] The UE can establish dual connectivity using a terrestrial 3GPP access technology (e.g., NR) and a satellite (non-terrestrial) 3GPP access technology (e.g., NR(LEO)), establish one or more (single access) PDU sessions on NR, and simultaneously use NR and NR(LEO) to establish one or more multi-access PDU sessions. Alternatively, the UE can establish dual connectivity using two terrestrial 3GPP access technologies (e.g., NR and E-UTRA), or use one terrestrial 3GPP access technology (e.g., NR) and one non-3GPP access technology (e.g., trusted WLAN access) to establish dual connectivity.

[0413] In this disclosure, "multi-access" and "multi-connection" refer to scenarios where a UE registers to a network through multiple ATs.

[0414] 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 consumption of the entire communication system is the sum of the energy consumption of all communication equipment in the system. The energy efficiency of the communication system / communication equipment reflects the efficiency of energy consumption and can be defined as the ratio of the amount of data transmitted to energy consumption, or the ratio of the communication area covered / served to energy consumption. Energy efficiency can be measured for the entire network, subnet (such as the wireless access network), individual network equipment, communication site (such as a data center), terminal, etc.

[0415] 5G networks can guide UEs in selecting one or more access technologies to transmit application / service data by sending them policies or rules (e.g., UE Routing Selection Policy (URSP) and Access Traffic Steering Switching Splitting (ATSSS) rules) for transmitting application / service data over (single access) PDU sessions and / or multi-access PDU sessions. However, these policies and rules currently do not consider UE or network energy consumption and efficiency.

[0416] When a UE uses multiple access technologies to simultaneously connect to the network and / or transmit data, it increases network and UE energy consumption. Existing technologies lack effective solutions for reducing network and UE energy consumption or improving energy efficiency in UE multi-access scenarios. For example, when a UE establishes multiple access connections and sessions using different access technologies (ATs), how does the network or UE decide (e.g., release or modify) existing connections and / or sessions to reduce network or UE energy consumption?

[0417] Based on the above technical problems, the embodiments of the present disclosure propose a communication method, device, and storage medium, which control the UE to use the first access technology AT and / or the second AT for communication through multi-access related subscription data or a first multi-access related policy, thereby reducing the impact of multi-access on the energy consumption of the network and / or UE, and improving the energy efficiency and performance of the network and UE.

[0418] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0492] In the communication method provided by the embodiment of the present disclosure, the UE obtains the multi-access related subscription data or the first multi-access related policy from the second network function entity, which reduces the calculation amount of the UE and further reduces the energy consumption of the UE.

[0493] FIG2 is a second flow chart of a communication method provided by an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure provides a communication method, the execution subject of which may be a network device, such as RAN, AMF, SMF, UDM, UDR, PCF, NEF, AF, NWDAF, etc. The method includes:

[0518] In some embodiments, before the network device determines the multiple access-related subscription data or the first multiple access-related policy based on the access-related information, the method further includes:

[0519] Access related information is obtained from the first network function entity.

[0520] Specifically, in the embodiment of the present disclosure, the first network function entity may be RAN, AMF, SMF, UDM, UDR, PCF, NEF, AF, NWDAF, etc.

[0521] In some embodiments, obtaining access-related information from the first network function entity includes:

[0536] Step 202: Control the UE to communicate using the first AT and / or the second AT based on the multiple access related subscription data or the first multiple access related policy.

[0537] Specifically, in an embodiment of the present disclosure, when the UE registers with the first network using the first AT and the second AT, the UE may be controlled to communicate using the first AT and / or the second AT based on the multiple access-related subscription data or the first multiple access-related policy.

[0538] Alternatively, after the UE registers with the first network using the first AT, it may also register with the first network using the second AT. Based on the multi-access related subscription data or the first multi-access related policy, the UE may be controlled to use the first AT and / or the second AT for communication.

[0539] In some embodiments, controlling the UE to communicate using the first AT and / or the second AT based on the multiple access-related subscription data or the first multiple access-related policy includes:

[0540] Sending multiple access related subscription data or a first multiple access related policy to the UE.

[0541] Specifically, in the embodiment of the present disclosure, the network device sends multiple access related subscription data or the first multiple access related policy to the UE.

[0550] Transferring a first QoS flow of a first session using a first AT to a connection using a second AT;

[0551] The QoS flow of a first application or service using a first AT is transferred to a connection using a second AT.

[0552] The communication method provided in the embodiment of the present disclosure controls the UE to use the first access technology AT and / or the second AT for communication through multi-access related subscription data or the first multi-access related policy, thereby reducing the impact of multi-access on the energy consumption of the network and / or UE, and improving the energy efficiency and performance of the network and UE.

[0553] The method in the above embodiment is further illustrated below with several specific examples.

[0554] Example 1:

[0555] FIG3 is a schematic diagram of a multi-access control signaling interaction provided by an embodiment of the present disclosure. As shown in FIG3 , the multi-access control may include the following steps:

[0556] 1. The UE accesses NG-RAN1 using the first access technology (AT1) and initiates a registration request with the network (e.g., AMF). The registration request carries an indication of the UE's ability to support multiple access. The AMF processes and accepts the UE's registration request. The multi-access-related process is detailed in steps 2-6.

[0557] 2.AMF obtains the subscription data from UDM, which includes the subscription information related to UE multi-access.

[0558] Specifically, for the UE / user, the UE multi-access related subscription information includes one or a combination of the following information:

[0559] (1) Allowing UE to use multiple ATs simultaneously (which can be indicated by AT type).

[0560] (2) Allow the use of multi-access network slices (which can be indicated by a single network slice auxiliary selection information S-NSSAI).

[0561] (3) Allowing the use of multiple access data networks (which can be indicated by the data network name DNN), such as a specific local access data network LADN.

[0562] 3. The AMF sends a policy request or event report to the PCF, which carries the information that the UE accesses / registers through AT1 and the indication that the UE supports multiple access.

[0563] 4. The PCF sends an event report to the AF, which carries the information that the UE accesses / registers through AT1 and the indication that the UE supports multiple access.

[0564] 5. The AF replies to the PCF with the application / service transmission policy on multiple accesses, i.e., the application / service transmission policy on AT1. For a specific application / service, the application / service transmission policy on multiple accesses includes one or a combination of the following information:

[0565] (1) Allow or prohibit the simultaneous use of multiple ATs (can be indicated by AT type).

[0566] (2) Allow or prohibit the use of network slices for multiple access transmission (which can be indicated by single network slice auxiliary selection information S-NSSAI). And / or,

[0567] (3) Data networks that allow or prohibit the use of multi-access transmission (can be indicated by the data network name DNN and the data network access identifier DNAI).

[0568] 6. The PCF responds to the AMF with the UE multi-access related policy, i.e., the policy for transmitting applications / services on AT1. Specifically, the UE multi-access related policy may include one or a combination of the following information:

[0569] (1) The UE cannot use multiple ATs simultaneously.

[0570] (2) When there are connections with other ATs, release AT1 (eg, satellite access technology).

[0571] (3) ATs arranged by priority: When a UE uses a high-priority AT to access, the ATs with lower priorities are released.

[0572] (4) Multiple ATs that a UE can use simultaneously.

[0573] (5) Application / service multi-access transmission policy. For details, see step 5. The PCF can determine this policy based on the information provided by the AF (see steps 4-5) or the PCF local policy.

[0574] (6) Timer 1 is used to instruct the network to release or modify AT1's PDU session (or a branch of a multi-access PDU session) and / or release AT1's connection only when the UE successfully accesses the network through another AT (e.g., AT2) for a period exceeding timer 1 (e.g., 2 minutes).

[0575] (7) Time period or area information, used to indicate that only within the specified time period or area will AT1's PDU session (or a branch of a multi-access PDU session) be released or modified, and / or AT1's connection be released.

[0576] 7. The UE establishes one or more PDU sessions (or branches of a multi-access PDU session) through AT1.

[0577] 8. The UE accesses NG-RAN2 using the second access technology (AT2) and initiates a registration request to the network (e.g., AMF). The UE provides NG-RAN2 with the GUAMI of the AMF in step 1 (e.g., the parameter carried in the RRC Setup Complete message). NG-RAN2 selects the AMF based on the GUAMI. That is, the same AMF manages the UE's access (including registration and service requests) through AT1 and AT2.

[0578] The AMF determines whether to accept the UE's registration request via AT2 based on the UE's subscription data. For example, if the network slice the UE requests to access allows the UE to use multiple access, the AMF accepts the UE's registration request via AT2.

[0579] 9. The AMF sends a policy request or event report to the PCF, which carries the information that the UE accesses / registers through AT2 and the indication that the UE supports multiple access.

[0580] 10. The PCF sends an event report to the AF, which carries the information that the UE accesses / registers through AT2 and the indication that the UE supports multiple access.

[0581] 11. The AF replies to the PCF with the policy for transmitting the application / service on multiple access, that is, the policy for transmitting the application / service on AT2.

[0582] 12. The PCF responds to the AMF with the UE multi-access related policies, i.e., the PCF responds to the AMF with the policy for transmitting applications / services on AT2.

[0583] 13. The AMF determines to release or modify the PDU session (or branch of the multi-access PDU session) established by the UE using AT1 based on the policy provided by the PCF or the AMF local policy.

[0584] Specifically, the network function entity NF (such as PCF, AMF, SMF, AF) can determine the multi-access related network policy or contract information based on the energy-saving requirements or energy consumption / energy efficiency of the network of different ATs. Including: based on the current energy consumption / energy efficiency of the network or UE of different ATs, statistical information of past energy consumption / energy efficiency, and / or predicted information of future energy consumption / energy efficiency, the above network policy or contract information can be dynamically adjusted. Specifically, it can include one of the following methods:

[0585] (1) The NF (e.g., PCF, AMF, SMF, AF, or NEMF (Network Energy Consumption and Efficiency Management Function)) obtains network energy consumption / efficiency analysis information (including statistical or forecast information) of one or more ATs from the NWDAF. The NEMF can determine the network energy consumption / efficiency information of one or more ATs based on the analysis information and / or network configuration.

[0586] (2) NF (eg, PCF, AMF, SMF, AF) determines the above multi-access related strategies based on the above analysis information, or based on the network energy consumption / energy efficiency information of one or more ATs provided by NEMF.

[0587] For example: If the network supporting a specific AT has (relatively) high energy consumption or (relatively) low energy efficiency, or the network supporting a specific AT (such as a satellite access network) has (relatively) high energy saving requirements, the NF (such as PCF, AMF, SMF) sets the release of the AT in the multi-access related policy, or sets the AT to a lower priority, or uses the AT to transmit applications / services with (relatively) low energy consumption.

[0588] 14. The AMF (or PCF) triggers the SMF to transfer / handover (all or part of) the sessions or QoS flows on AT1 to AT2. Alternatively, the AMF (or PCF) triggers the UE to transfer / handover (all or part of) the sessions or QoS flows on AT1 to AT2.

[0589] 15. Optionally, if the connection of AT1 is to be released, the AMF initiates a deregistration procedure for AT1 to the UE, or the UE initiates a deregistration procedure for AT1.

[0590] Example 2:

[0591] FIG4 is a second schematic diagram of multiple access control signaling interaction provided by an embodiment of the present disclosure. As shown in FIG4 , multiple access control may include the following steps:

[0592] 0. The UE accesses NG-RAN1 using AT1 and initiates a registration request with the network (e.g., AMF). The AMF processes and accepts the UE's registration request. The UE establishes one or more PDU sessions (or branches of a multi-access PDU session) through AT1. Subsequently, the UE accesses NG-RAN2 using AT2 and initiates a registration request with the network (e.g., AMF).

[0593] 1.AMF sends an event notification to SMF, which carries the information that the UE accesses or registers through AT2.

[0594] Alternatively, if the AMF determines to trigger the release or modification of the PDU session (or a branch of a multi-access PDU session) established by the UE using AT1 based on the multi-access related policy provided by the PCF or the AMF's local multi-access related policy, then:

[0595] If the AMF determines to trigger the release of the PDU session (or a branch of a multi-access PDU session) established by the UE using AT1, the AMF initiates a session release request (or a multi-access PDU session modification request) to the SMF, which carries the identifier of the PDU session to be released.

[0596] If the AMF determines to trigger the modification of the PDU session (or branch of the multi-access PDU session) established by the UE using AT1, the AMF initiates a session update request or a session transfer request to the SMF, which carries the identifier of the PDU session to be modified and the source access type (i.e., AT1); if the AMF determines to trigger the transfer of all or part of the sessions or QoS flows (corresponding to specific applications / services) of AT1 to AT2, the request message also carries the target access type (i.e., AT2) and / or information about the UE accessing or registering through AT2.

[0597] 2.SMF obtains the subscription data from UDM, which includes the session management subscription information related to UE multi-access.

[0598] Specifically, for the UE / user, the UE multi-access related session management subscription information includes one or a combination of the following information:

[0599] (1) Multiple ATs can be used simultaneously (can be indicated by AT type).

[0600] (2) Allow the use of multi-access network slices (which can be indicated by a single network slice auxiliary selection information S-NSSAI).

[0601] (3) Allow the use of multi-access data networks (which can be indicated by the data network name DNN).

[0602] 3. The SMF sends a policy request to the PCF, which carries the source access type (i.e., AT1), the target access type (i.e., AT2), and / or information about the UE accessing (or registering, or establishing / modifying a PDU session) through AT2.

[0603] 4. Optionally, the PCF sends an event report to the AF, which carries information about the UE accessing (or registering, or establishing / modifying a PDU session) through AT2.

[0604] 5. Optionally (if step 4 is executed, then execute this step), the AF replies to the PCF with the application / service multi-access transmission policy. For a specific application / service, the application / service multi-access transmission policy includes one or a combination of the following information:

[0605] (1) Allow or prohibit the simultaneous use of multiple ATs (can be indicated by AT type).

[0606] (2) Allow or prohibit the use of network slices for multiple access transmission (which can be indicated by single network slice auxiliary selection information S-NSSAI). And / or,

[0607] (3) Data networks that allow or prohibit the use of multi-access transmission (can be indicated by the data network name DNN and the data network access identifier DNAI).

[0608] 6. PCF replies to SMF with the UE multi-access related session management policy. Specifically, the UE multi-access related session management policy may include the following information:

[0609] (1) The UE cannot use multiple ATs simultaneously when establishing a PDU session.

[0610] (2) When there are connections with other ATs, the PDU session (or a branch of a multi-access PDU session) of AT1 (eg, satellite access technology) is released.

[0611] (3) Prioritized ATs: When a UE accesses an AT with a high priority, the PDU session (or branch of a multi-access PDU session) of the AT with a low priority is released.

[0612] (4) The UE can use multiple ATs simultaneously when establishing a PDU session.

[0613] (5) Application / service multi-access transmission policy. See step 5. The PCF may determine this policy based on information provided by the AF (see steps 4-5) or PCF local policy.

[0614] (6) Timer 1, which instructs the network to release or modify AT1's PDU session (or a branch of a multi-access PDU session) only when the UE successfully accesses the network through another AT (e.g., AT2) for a period exceeding timer 1 (e.g., 2 minutes). (Note: The SMF may determine whether this condition is met based on event notifications received from the AMF regarding the UE's access / registration with AT1 and other ATs.)

[0615] (7) Time period or area information, used to indicate that the PDU session of AT1 (or a branch of a multi-access PDU session) is released or modified only within the specified time period or area.

[0616] 7. The SMF determines to release or modify the PDU session established by the UE using AT1, and / or transfer all or some sessions or applications / services of AT1 to AT2, based on the multi-access-related session management policy provided by the PCF or the local multi-access-related session management policy of the SMF. The SMF sends a message transfer request to the AMF, including the following situations:

[0617] (1) If the SMF determines to release the PDU session (or a branch of a multi-access PDU session) established by the UE using AT1, the request carries PDU session resource release information (or multi-access PDU session resource modification information) sent to NG-RAN1 and a PDU session release command (or multi-access PDU session modification command) sent to the UE.

[0618] (2) If the SMF determines to transfer the PDU session of AT1 (or all QoS flows of the multi-access PDU session branch) to AT2, the request carries the PDU session resource release information (or multi-access PDU session resource modification information) sent to NG-RAN1 and the PDU session resource establishment information (or multi-access PDU session resource modification information) sent to NG-RAN2.

[0619] (3) If the SMF decides to modify the PDU session (or a branch of a multi-access PDU session) established by the UE using AT1 and transfer some QoS flows (corresponding to specific applications / services) in the session to AT2, the request carries PDU session resource modification information sent to NG-RAN1, PDU session resource establishment information (or multi-access PDU session resource modification information) sent to NG-RAN2, and a PDU session modification command sent to the UE.

[0620] Alternatively, if step 1 is a session release request, the SMF sends a session release response to the AMF, which carries the PDU session resource release information sent to NG-RAN1 and the PDU session release command sent to the UE.

[0621] If step 1 is a session update request or a session transfer request, the SMF sends a session update response or a session transfer response to the AMF, which carries the PDU session resource modification information or PDU session resource release information (or multi-access PDU session resource modification information) sent to NG-RAN1, the PDU session resource establishment information (or multi-access PDU session resource modification information) sent to NG-RAN2, and the PDU session modification command sent to the UE.

[0622] 8-13. Based on the message sent by the SMF, the AMF forwards the PDU session resource modification information or PDU session resource release information to NG-RAN1, forwards the PDU session resource establishment information (or multi-access PDU session resource modification information) to NG-RAN2, and forwards the PDU session modification command or PDU session release command to the UE via NG-RAN1 or NG-RAN2. NG-RAN1, and NG-RAN2 (if NG-RAN2 receives the PDU session resource establishment information (or multi-access PDU session resource modification information)), initiates radio resource reconfiguration to the UE. This completes the session establishment (or multi-access PDU session branch modification) on NG-RAN2 / AT2 and the session modification or release process (or multi-access PDU session branch) on NG-RAN1 / AT1, thereby transferring all or part of AT1's sessions (or multi-access PDU session branches) or QoS flows.

[0623] Example three:

[0624] FIG5 is a third schematic diagram of multiple access control signaling interaction provided by an embodiment of the present disclosure. As shown in FIG5 , multiple access control may include the following steps:

[0625] 1. When triggered by one or a combination of the following conditions, the PCF decides to send or update the multi-access related UE policy to the UE.

[0626] (1) The UE requests the network for UE policies related to multiple access. The request message carries the UE's multiple access capability indication and the types of ATs that the UE supports simultaneous access (e.g., AT1, AT2). The AMF forwards the UE's request to the PCF.

[0627] (2) The PCF receives an event report / event notification from the AMF regarding UE registration. For example, the UE registers through AT1 and the UE registers through AT2. Based on this, the PCF determines that the UE is registered to the network through multiple ATs.

[0628] (3) The PCF receives the transmission policy (update) of the service / application on a specific AT (eg, AT1, AT2) sent by the AF, and accordingly determines that a multi-access related UE policy needs to be sent or updated.

[0629] (4) The PCF receives the multi-access related subscription information (update) sent by the UDM / UDR and determines that the multi-access related UE policy needs to be sent or updated. For the multi-access related subscription information, see Examples 1 and 2.

[0630] 2-3. The PCF sends / updates the multi-access related UE policy to the UE via the AMF. The AMF forwards the multi-access related UE policy to the UE.

[0631] Specifically, the multi-access related UE policy may include one or a combination of the following information:

[0632] (1) The UE cannot use multiple ATs simultaneously;

[0633] (2) Release AT1 when there are connections with other ATs (e.g., satellite access technology);

[0634] (3) ATs arranged by priority: When a UE uses a high-priority AT to access, the ATs with lower priorities are released.

[0635] (4) Multiple ATs that a UE can use simultaneously.

[0636] (5) Application / service multi-access transmission strategy. See Examples 1 and 2.

[0637] (6) Timer 1, used to indicate that the UE will release or modify the PDU session of AT1 (or a branch of a multi-access PDU session) and / or release the connection of AT1 only when the UE successfully accesses the network through another AT (e.g., AT2) for a period exceeding timer 1 (e.g., 2 minutes).

[0638] (7) Time period or area information, used to indicate that only within the specified time period or area will AT1's PDU session (or a branch of a multi-access PDU session) be released or modified, and / or AT1's connection be released.

[0639] 4. The UE receives the UE policy related to multiple access. If the UE is currently registered to the network through multiple access, such as AT1 and AT2, the UE determines to transfer all or part of the sessions or QoS flows on AT1 to AT2 based on the UE policy related to multiple access.

[0640] 5. The UE initiates PDU session establishment and / or session modification on AT2, and PDU session modification or release on AT1, thereby transferring all or part of AT1's sessions or QoS flows (e.g., PDU Session 1, QoS Flow 1 of PDU Session 2) to AT2.

[0641] Example 4:

[0642] FIG6 is a fourth schematic diagram of multi-access control signaling interaction provided by an embodiment of the present disclosure. As shown in FIG6 , multi-access control may include the following steps:

[0643] 1. The UE locally determines a multi-access related policy. The policy may include one or a combination of the following information:

[0644] (1) UE cannot use multiple ATs simultaneously.

[0645] (2) When there are connections with other ATs, release AT1 (eg, satellite access technology).

[0646] (3) ATs arranged by priority: When a UE uses a high-priority AT to access, the ATs with lower priorities are released.

[0647] (4) Multiple ATs that a UE can use simultaneously.

[0648] (5) For specific applications / businesses:

[0649] Allow or prohibit the simultaneous use of multiple ATs;

[0650] Allow or disallow the use of network slicing for multi-access transport; and / or,

[0651] Allow or disallow the use of multiple access transport for data networks.

[0652] (6) When the UE uses AT1 and other ATs simultaneously, specific applications / services are prioritized or prohibited from being transmitted on AT1 and / or other ATs. For example: 1) Voice applications / services are prioritized on AT1 (which can be indicated by application identifiers or service types), while data applications / services are prioritized on other ATs (e.g., AT2); 2) Video applications / services are prohibited from being transmitted on AT1 (or other ATs).

[0653] (7) Timer 2 is used to instruct the network to release or modify AT1's PDU session (or a branch of a multi-access PDU session) and / or release AT1's connection only when the UE successfully accesses the network through another AT (e.g., AT2) for a period exceeding timer 2 (e.g., 3 minutes).

[0654] (8) Time period or area information, used to indicate that AT1's PDU session (or a branch of a multi-access PDU session) is released or modified, and / or AT1's connection is released, within the specified time period or area.

[0655] The UE may determine a UE multi-access policy based on the energy consumption / energy efficiency of the UE's access to a specific AT. Specifically, the UE may determine and dynamically adjust the policy based on energy consumption / energy efficiency statistics of the UE's previous access to the specific AT and / or energy consumption / energy efficiency predictions of the UE's future access to the specific AT. For a method for the UE to obtain energy consumption / energy efficiency statistics or predictions for the UE's access to a specific AT, see Example 5.

[0656] 2. If the UE is currently registered to the network through multiple access, such as AT1 and AT2, the UE determines to transfer all or part of the sessions or QoS flows on AT1 to AT2 based on the UE policy related to the multiple access.

[0657] 3. The UE initiates PDU session establishment and / or session modification on AT2, and PDU session modification or release on AT1, thereby transferring all or part of AT1's sessions or QoS flows (e.g., PDU Session 1, QoS Flow 1 of PDU Session 2) to AT2.

[0659] FIG7 is a schematic diagram of access-related information analysis signaling interaction according to an embodiment of the present disclosure. As shown in FIG7 , the access-related information analysis process may include the following steps:

[0660] 1. The NF or UE sends an analysis information request or subscription message to the NWDAF to request or subscribe to the energy consumption / energy efficiency analysis information of the network or UE for a specific AT.

[0661] Specifically, the analysis information request or subscription message carries the following parameters:

[0662] Analysis ID / Type: Indicates whether to perform energy efficiency or energy consumption related analysis. For example: Analytics ID = Energy Efficiency, or Analytics ID = Energy Consumption.

[0663] Target of analysis report: one or more terminal identities (such as SUPI) or terminal group identifiers, or "any UE".

[0664] The analysis filtering information is shown in Table 1. In particular, the analysis filtering information includes an AT type, which is used to indicate a request / subscription for the energy consumption / energy efficiency analysis information of the network or UE of a specific AT.

[0665] Analytical accuracy.

[0666] Target analysis time, indicating the time range of the requested statistical or forecast information.

[0667] Notification association identifier and notification target address, used to subscribe to analysis information.

[0668] Reporting Thresholds can be used for anomaly detection. For example, Reporting Thresholds = maximum energy consumption, maximum energy consumption ratio, or lowest energy efficiency. The maximum energy consumption or maximum energy consumption percentage can be used to instruct the NWDAF to report relevant analysis information when the statistical or predicted value of the network or UE's energy consumption using a specific AT reaches or exceeds the threshold. The lowest energy efficiency can be used to instruct the NWDAF to report relevant analysis information when the statistical or predicted value of the network or UE's energy efficiency using a specific AT reaches or falls below the threshold.

[0669] Table 1 Analysis and filtering information

[0670] 2. Based on the analysis information request or subscription message, NWDAF collects the energy consumption / energy efficiency related data of the network or UE for the specific AT as input data for training the energy consumption / energy efficiency model of the network or UE for the specific AT and obtaining the requested analysis information.

[0671] NWDAF can collect relevant input data from OAM, network function entities NF (such as network energy efficiency management function (NEMF), access network AN (such as NG-RAN), AMF, SMF, UPF, etc.), or UE. Specifically, the type and description of the input data are shown in Table 2.

[0672] Table 2 Type and description of input data

[0673] The NWDAF uses the collected input data to train an energy consumption / energy efficiency model of a specific AT's network or UE, and further obtains energy consumption / energy efficiency analysis information of the specific AT's network or UE based on the trained model and the input data.

[0674] Specifically, the obtained energy consumption / energy efficiency analysis information of the network or UE of the specific AT is shown in Table 3. The analysis information may include: statistical information of energy consumption / energy efficiency of the network or UE for the specific AT, and / or prediction information of energy consumption / energy efficiency of the network or UE for the specific AT.

[0675] Table 3 Output analysis information

[0676] 3. The NWDAF sends a reply or notification message to the NF or UE, which carries the energy consumption / energy efficiency analysis information of the network or UE for the specific AT.

[0677] 4. By (repeatedly) executing steps 1-3, the NF (e.g., AF, PCF) or UE obtains network or UE energy consumption / efficiency analysis information for different ATs (e.g., AT1, AT2) from the NWDAF. Based on the network or UE energy consumption / efficiency analysis information for different ATs, the NF or UE determines a multi-access-related policy (see Examples 1 to 4).
