XR traffic and/or media traffic requires higher throughput and lower latency, has higher power consumption and consumes more network resources. Therefore, a tradeoff between QoS and device power consumption needs to be considered. There is currently no corresponding QoS and policy mechanism to meet the above series of corresponding needs.

Therefore, how to balance UE power consumption and XR service/media service transmission performance, such as balancing UE battery duration and throughput, delay, reliability, etc. of data service is a challenge to be solved.

As shown in fig. 2, an embodiment of the present disclosure provides an information transmission method, which is performed by an AMF, including:

step 201: and sending UE state information of the UE to an access network function, wherein the UE state information is used for the access network function to determine service data flow transmission of the UE and/or QoS parameters of the service data flow transmission.

The UE status information may be used to indicate the status of the UE. The UE status may include, but is not limited to, at least one of: load conditions of the UE, UE battery conditions, temperature conditions of the UE, power consumption conditions of the UE, and the like.

The UE status information may be used to determine traffic data flows and/or quality of service QoS parameters for said traffic data flows by the access network function. Here, the access network function may be implemented by an access network device such as a base station.

In one possible implementation, determining traffic data flow delivery by an access network function includes: it is determined by the access network function whether traffic data streaming is performed.

The traffic data stream may have one or more. The access network function may determine one or more traffic data flows to transmit.

Here, the QoS parameters include, but are not limited to, at least one of: (1) a QoS class indication (QoS Class Identifier, QCI); assigning a reservation priority (Allocation and Retention Priority, ARP); guaranteed bit rate (Guaranteed Bit Rate, GBR); maximum Bit Rate (MBR); the combined maximum bit rate (Aggregated Maximum Bit Rate, AMBR). Here, qoS may be for a traffic data flow.

Here, different QoS parameters may be set for different UE states. For example, different QoS parameters may be set for different UE battery power levels. For example, qoS parameters with lower power consumption may be configured for a battery level of lower battery power of the UE.

In one possible implementation, the traffic data stream transmission and/or the quality of service QoS parameters of the traffic data stream transmission may have an impact on the UE state.

the battery power of the UE;

the battery use duration of the UE;

a power mode of the UE;

the temperature state of the UE.

The battery power of the UE may be represented by a battery power level. For example, battery power may be divided from 0% to 100% into a plurality of battery power levels, with different battery power levels indicating different battery power ranges.

The battery usage duration of the UE may include at least one of: the use period of the remaining battery power, the used period of the battery, and the like.

The power mode of the UE may include at least one of: battery powered, external power (e.g., mains powered), hybrid power (battery combined mains powered, etc.).

The temperature state of the UE may include the temperature of one or more of the different temperature measurement points of the UE. For example, the temperature state of the UE may include at least one of: the temperature state of the UE processor, the temperature state of the UE battery.

In one possible implementation, the temperature state of the UE is represented by a battery temperature level. For example, the temperature state of the UE may be represented by three temperature levels, high, medium, and low.

In one embodiment, the service data flow of the UE includes at least one of:

the extended reality XR service data flow of the UE;

and the multi-mode data service data flow of the UE.

XR-type service data flows typically have high bandwidth, low latency and high reliability requirements, thus resulting in outstanding UE power consumption. Here the traffic has a strong correlation with the UE state indicated by the UE state information.

The multi-mode data service data stream is used for transmitting data of different modes, so that the multi-mode data service data stream also has the characteristics of high bandwidth, low time delay and high reliability, and therefore, the UE energy consumption is outstanding. Here the traffic has a strong correlation with the UE state indicated by the UE state information

For example, XR service data flows consume a large amount of battery power, raise the temperature of the UE, and so on.

Here, the QoS parameters of traffic data flows that are allowed to be transmitted and/or traffic data flows that are not allowed to be transmitted may be determined by an access network function or the like according to the UE status information.

In one possible implementation, the access network function may determine a traffic data flow transmission and/or a quality of service QoS parameter of the traffic data flow transmission that is satisfied with the UE state indicated by the UE state information.

For example, when the battery power of the UE is low or the temperature of the UE is high, the traffic data stream transmission can be reduced, so that the energy consumption of the traffic data stream transmission is reduced, thereby improving the battery power supply duration and reducing the temperature of the UE.

When the battery power of the UE is low or the temperature of the UE is high, qoS parameters can be adjusted, transmission bandwidth and the like are reduced, so that the energy consumption for transmitting service data flows is reduced, the battery power supply duration is prolonged, and the temperature of the UE is reduced.

For another example, when the UE is powered by the mains and the UE temperature is low, qoS parameters may be adjusted, improving transmission bandwidth, reducing transmission delay, etc.; thereby improving the user experience.

Here, the UE status information may be sent by the core network element AMF to the access network function, instead of being sent directly by the UE to the access network function. Therefore, the influence on air interface data transmission caused by the fact that the UE directly sends the UE state information to the access network function can be reduced, and compatibility is improved.

In one possible implementation, the UE status information is sent by the UE to the core network via NAS messages.

The UE may determine its own UE status and send it to the core network via UE status information. The UE status information may be sent to the core network in NAS messages, such as to AMF, SMF, PCF and/or UMD, etc. And then the core network element such as AMF and the like sends the core network element to the access network function.

As shown in fig. 3, an embodiment of the present disclosure provides an information transmission method, which is performed by an AMF, including at least one of:

step 301a: receiving the UE state information sent by the UE;

step 301b: receiving the UE status information from a UDM;

step 301c: and receiving the UE state information from PCF.

Step 301a and/or step 301b and/or step 301c may be performed alone or in combination with step 201.

In one possible implementation, the UE status information may be sent by the UE to the AMF. For example, the UE status information may be sent to the AMF in the NAS.

In one possible implementation, the UE status information may be sent to the core network element by the UE in advance and stored in the UDM.

In one possible implementation, the UE state information may be an AF that the UE's application sends to the core network, and is sent by the AF to the NEF, which is then stored in the UDM.

In one possible implementation, the UE status information may be associated with a validity duration. The validity time may be stored in UDM/UDR and NF. The UDM may provide the UE status information to the core network element (e.g., AMF and/or SMF) for a valid duration. Upon expiration of the validity period, each node automatically deletes the UE state information. The UDM may delete the UE status information without explicit signaling.

In one possible implementation, the UDM may pre-authorize the AF and/or NEF to transmit UE status information. For example: the UDM may pre-authorize the AF and/or NEF to transmit communication signaling carrying UE status information.

The AMF may obtain the UE status information from the UDM by means of subscription or the like. The AMF may also obtain UE status information from the UDM by retrieving from the UDM, etc.

In one possible implementation, the UE status information may be sent by the UE to the PCF.

In one possible implementation, the UE state information may be an AF that the UE's application sends to the core network and is sent by the AF to the PCF. Here, the AF may be a trusted AF.

In one possible implementation, the UE state information may be an AF that the UE's application sends to the core network, and is sent by the AF to the NEF, which is then stored in the PCF.

The PCF may send UE status information to the AMF based on subscription information of the AMF, etc.

In one possible implementation, the PCF may send UE status information to the AMF based on subscription information of the AMF, etc.

In one possible implementation, the AMF retrieves the UE status information in the PCF.

In one possible implementation, the NEF may send separate UE status information to the UDM. The UDM may store individual UE status information.

In one possible implementation, the NEF may send to the UDM an expected UE behavior parameter (Expected UE Behaviour Parameters), and the UE status information may be part of the expected UE behavior parameter. The UDM may store expected UE behavior parameters, wherein the expected UE behavior parameters may include UE state information.

The UE status information stored by the UDM may be identified using the identification information of the UE. Here, the identification information of the UE includes, but is not limited to: SUPI.

In one possible implementation, the expected UE behavior parameter characterizes an expected behavior of a UE or a group of UEs. The set of these UE behavior parameters may be provided by the NEF for storage as part of the UE data.

The AMF retrieves from the UDM the AMF related expected UE behavior parameters, which may be related to PDU session and SMS transmission.

The expected UE behavior parameters may be specified as shown in table 1: the UE status information in the expected UE behavior parameters may include at least one of: power mode, UE temperature, overheat condition, battery level of the UE, battery indication.

TABLE 1

the UE status information stored for the AMF is received from the UDM.

After receiving the UE status information, the UDM may store the UE status information as UE status information of different classifications for reading by different network elements. For example, the UDM may store UE status information as UE status information for AMF to read, and UE status information for SMF to read. The UE status information may be stored in AMF-associated information and/or the UE status information may be stored in SMF-associated information.

In one possible implementation, the UE status information for AMF reading is UE-specific, and the UE status information for SMF reading may be PDU session specific.

The UE status information stored for the AMF may be used for an access network function to determine transmission parameters of a predetermined data service of the UE.

The UE status information stored for the SMF may be used for an access network function to determine transmission parameters of a predetermined data service in a particular PDU session of the UE (e.g., a PDU session corresponding to a PDU session establishment request).

The AMF can subscribe to the UE state information (including the expected UE behavior parameters containing the UE state information) in advance, and after receiving the UE state information, the UDM can notify a subscriber (AMF, SMF and the like) of the UE state information through a Notification message (such as Nudm_SDM_notification) to update the UE state information. The UE status information may be carried in a notification message. Thus, the AMF and/or SMF, etc. may acquire UE status information.

In one possible implementation, the UE status information may be identified using UE identification information.

In one possible implementation, the UE status information may be identified with DNN/S-NSSAI for association with the PDU session.

Illustratively, the UE status information is carried in expected UE behavior parameters. The UDM performs nudm_sdm_notification (including: SUPI or internal group identifier (Internal Group Identifier), AMF associated expected UE behavior parameters, subscribed periodic registration timer (Subscribed Periodic Registration Timer), subscribed activation time (subscribed Active Time), etc.) service operations. The AMF identifies whether there are overlapping parameter sets and merges the parameter sets in the expected UE behavior if necessary. The AMF uses the received expected UE behavior parameters (including UE state information) to derive UE configurations applicable to NAS parameters and to derive core network assisted RAN parameters. The AMF may also determine the registration area based on a parameter fixed indicator (Stationary indicator) or an expected UE movement trajectory (Expected UE Moving Trajectory).

and receiving a UE registration request carrying the UE state information.

The UE may send UE status information to the AMF during the registration of the UE to the core network. During the registration process, the UE may register a request (Registration Request) with the access network function UE, carrying UE status information in the NAS message. The access network function may first select the AMF and then forward NAS messages carrying the status information of the receiving UE to the AMF.

In one possible implementation, the UE will send UE status information to the AMF during a mobility registration update procedure. As such, UE status information may be sent to the AMF or updated.

If the UE requests the UE status information in AMF mode through the UE registration request, the UE status information may be carried in PCO of the UE registration request and/or UE mobility management core network capability information, such as UE 5MM Core Network Capability information.

As shown in fig. 4, an embodiment of the present disclosure provides an information transmission method, which is performed by an AMF, including:

Step 401: and sending the UE state information to a PCF, wherein the UE state information is used for determining a non-session policy and/or a session policy associated with the UE by the PCF.

Step 401 may be implemented alone or in combination with step 201, step 301a, step 301b and/or step 301 c.

If the SMF determines during PDU session establishment that the PDU session uses dynamic PCC, the SMF performs PCF selection. The PCF may generate/activate rules for corresponding service data flows, such as XR-type service rules/multi-mode service rules, or generate/activate PCC rules for enhancing data flows supporting data services (e.g., XR-type services and multi-mode service sessions), based on application information provided by subscription and AF. (e.g., associate XRM traffic data flows, match XRM traffic and multi-modal traffic QoS, GFBR, PDB, MDBV match including XRM and multi-modal traffic data flows, etc.).

AMF reports UE state information to PCF; the AMF report conditions may include, but are not limited to, at least one of: the PCF subscribes to the UE state change event and reporting conditions are met, or subscription information or local policy triggers reporting of UE state information. According to the subscription and reporting requirements, UE status information notification (UE status information notify) reporting is performed.

Policy and charging control policies established by PCF include session related policies and non-session related policies. Wherein, the non-session related policies include UE policies provided to the UE, access and mobility management policies provided to the AMF and SMF selection policies; the session related policies mainly provided for SMF, including charging policies, policies for gating and QoS control, usage monitoring policies, application detection policies, session related network capability opening policies, etc.;

the PCF may determine a non-session UE policy and/or session policy for the UE based on the received UE status information. The PCF may set non-session policies and/or session policies for different UEs for different UE states. And issuing the updated non-session policy and/or session policy to the AF and the UE.

For example, when the battery power of the UE is low, or the UE temperature is high, the non-session policy and/or session policy may be adjusted, the transmission bandwidth is reduced, and the energy consumption of the data service is reduced, thereby increasing the battery power supply duration and reducing the UE temperature.

For another example, when the UE is powered by the mains and the UE temperature is low, non-session policies and/or session policies may be adjusted, improving transmission bandwidth, reducing transmission delay, etc.; thereby improving the user experience.

In this way, the PCF sets the non-session policy and/or session policy of the UE according to the UE state information, so as to balance the UE state such as UE energy consumption and the UE transmission performance.

The AMF sends the UE status information to the access network function in an N2 message.

The AMF sends the UE status information to the access network function using NGAP signaling.

In one possible implementation, the AMF may send a registration accept message to the UE, the registration accept message carrying an N2 message, wherein the N2 message carries the UE status information.

As shown in fig. 5, an embodiment of the present disclosure provides an information transmission method performed by a UDM, including

Step 501: and sending UE state information to an AMF, wherein the UE state information is used for sending the AMF to an access network function so that the access network function can determine the UE service data stream transmission and/or QoS parameters of the service data stream transmission.

In one embodiment, the service data flow of the UE includes at least one of:

the extended reality XR service data flow of the UE;

and the multi-mode data service data flow of the UE.

The UDM may store and update UE status information.

In one possible implementation, the UE status information stored by the UDM may be sent by the UE to the UDM.

For example, the application of the UE may send UE status information to the UDM through AF and NEF.

The UE may determine its own UE status and send it to the UDM via UE status information. And then the UDM sends the result to an access network function through AMF and the like.

Here, the UE status information may be transmitted by the UDM to a core network function such as AMF or the like. The UE status information is sent by the AMF to the access network function and not directly by the UE to the access network function. Therefore, the influence on air interface data transmission caused by the fact that the UE directly sends the UE state information to the access network function can be reduced, and compatibility is improved.

In this way, the UDM sends UE status information of the UE to the access network function through NF, and the access network function determines transmission parameters of the UE according to the UE status information, on one hand, balances UE status such as UE energy consumption and transmission performance of data services such as XR media services. On the other hand, the core network NF is used for sending the UE status information to the access network function, so that the influence on the air interface data transmission caused by the UE directly sending the UE status information to the access network function can be reduced, and the compatibility is improved.

As shown in fig. 6, an embodiment of the present disclosure provides an information transmission method performed by a UDM, including

Step 601: the UE status information is received from a NEF, wherein the UE status information is received from the UE by an AF and sent to the NEF.

Step 601 may be implemented alone or in combination with step 501.

In one possible implementation, the UE status information may be associated with a validity duration. The validity time may be stored in UDM/UDR and NF. The UDM may provide the UE status information to a core network element (e.g., AMF) for a valid duration. Upon expiration of the validity period, each node automatically deletes the UE state information. The UDM may delete the UE status information without explicit signaling.

In one embodiment, the sending UE status information to the AMF includes:

The UDM may send expected UE behavior parameters carrying UE status information to the AMF.

acquiring subscription information from a unified data store (UDR);

The UDM may read the corresponding subscription information from the UDR via nudr_dm_query to verify the required updates of the expected UE behavior parameters (including UE state information) and authorize the modification of these expected UE behavior parameters (including UE state information) for this subscriber or the corresponding AF group.

If the UDM authorizes the AF to provide the subscriber with the expected UE behavior parameters (including UE state information), the UDM parses the GPSI into SUPI and requests creation, update or deletion of the provided expected UE behavior parameters (including UE state information) as part of the subscription data via a Nudr_DM_Create/Update/Delete Request message.

If a new 5G VN group is created, the UDM may assign a unique inner group ID to the 5G VN group and include the newly assigned inner group ID in the Nudr_DM_CreateRequest message. If the list of 5G VN group members changes or the 5G VN group data changes, the UDM updates the expected UE behavior parameters (including UE status information) of the UE and/or the UE group subscription according to the AF/NEF request.

The UDR stores the provided expected UE behavior parameters (including UE status information) as part of the UE and/or UE group subscription data and responds with a nudr_dm_create/Update/Delete Response message.

If the AF is not authorized to provide the expected UE behavior parameters, the UDM indicates the cause of the failure in a Nudm_ParameterProvision_update response message.

In one embodiment, the method further comprises: and storing the UE state information into the AMF-associated information.

After receiving the UE status information, the UDM may store the UE status information as UE status information of different classifications for reading by different network elements. For example, the UDM may store UE status information as UE status information for AMF to read, and UE status information for SMF to read. UE status information may be stored in AMF-associated information. And/or may store UE status information in SMF-associated information

In one possible implementation, the sending UE status information to the AMF includes: AMF-specific UE status information stored in AMF manner

The AMF and/or SMF can subscribe to the UE state information (including the expected UE behavior parameters containing the UE state information) in advance, and the UDM can notify a subscriber (AMF, SMF and the like) of the UE state information to update the UE state information through a Notification message (such as Nudm_SDM_notification) after receiving the UE state information. The UE status information may be carried in a notification message. Thus, the AMF and/or SMF, etc. may acquire UE status information.

Illustratively, the UE status information is carried in expected UE behavior parameters. The UDM performs nudm_sdm_notification (SUPI or internal group identifier (Internal Group Identifier), SMF associated expected UE behavior parameter set, DNN/S-NSSAI, suggested downlink packet count (Suggested Number of Downlink Packets), etc.) service operations.

As shown in fig. 7, an embodiment of the present disclosure provides an information transmission method performed by a UDM, including

Step 701: and sending the UE state information to a PCF, wherein the UE state information is used for determining a non-session policy and/or a session policy associated with the UE by the PCF.

Step 701 may be performed alone or in combination with step 501 and/or step 601.

As shown in fig. 8, an embodiment of the present disclosure provides an information transmission method, which is performed by an access network function, including

Step 801: and receiving UE state information of UE sent by a core network, wherein the UE state information is used for the access network function to determine the UE service data stream transmission and/or QoS parameters of the service data stream transmission.

In one embodiment, the service data flow of the UE includes at least one of:

the extended reality XR service data flow of the UE;

and the multi-mode data service data flow of the UE.

Here, the UE status information may be sent by the core network element to the access network function, instead of being sent directly by the UE to the access network function. Therefore, the influence on air interface data transmission caused by the fact that the UE directly sends the UE state information to the access network function can be reduced, and compatibility is improved.

In this way, the core network sends the UE status information of the UE to the access network function, and the access network function determines the service data stream transmission of the UE and/or the QoS parameters of the service data stream transmission according to the UE status information, so that on one hand, the UE status such as UE energy consumption and the transmission performance of the service data stream such as XR media service are balanced.

In one possible implementation, the PCF may authorize the AF to pass the NEF-wise UE status information to the PCF.

In one possible implementation, the UE status information in the PCF may be sent by the UE to the PCF via AF and NEF. Or UDM may be sent to PCF.

In order to further explain any embodiments of the disclosure, several specific embodiments are provided below.

Here, the AMF may send UE status information to the access network function, so that the access network function determines QoS of the XR service and/or the multi-mode data service data flow, and better matches the XR service and/or the multi-mode data service flow characteristics with energy consumption management, including supporting balance of factors such as throughput, time delay, reliability, and the like considering the battery duration of the device. Ensuring business requirements and user experience

Example one,

UE status information is sent by the AF to the network through the NEF, stored in the UDM, and subscribed to by the AMF. The specific steps are as shown in fig. 10, including:

step 1000: NF subscribes to UDM notifications of UE and/or UE group data updates. I.e. the AMF subscribes to the UDM for XRM event information, e.g. UE status information).

Step 1001: AF is by at least one of: nnef_parameterProvisionCreate Request; the nnef_parameterProvisions_update Request provides new additions or updates of one or more parameters to the NEF. Wherein the parameters include: UE status information. Here, the UE status information is acquired by the AF from the application of the UE.

Here, the UE may be identified with a general public user identity (Generic Public Subscription Identifier, GPSI), with a transaction reference ID (Transaction Reference ID) identifying the case of a transaction request between NEF and AF for nnef_parameter provision_create, the NEF assigning a transaction reference ID to the nnef_parameter provision_create request.

The NEF determines whether the requester is allowed to perform the requested service operation by checking an identifier of the requester (e.g., an AF identifier).

The payload of the nnef_parameterprovision_update Request may include at least one of the following parameters:

UE behavior parameters are expected (Expected UE Behaviour Parameters). Here, the UE status information may be transmitted to the NEF as expected UE behavior parameters.

UE status information. The UE status information may be transmitted to the NEF as separate information.

Network configuration parameters.

Step 1002: if the AF is authorized by NEF to provide parameters (including UE status information), NEF requests creation, update, and storage of the provided parameters as part of the subscription data through a message such as Nudm_ParameterProvisionCreateReques or Nudm_ParameterProvisionUpdate Reques, the message including the provided parameters (including UE status information) and NEF reference ID. The NEF stores the UE status information into the UDM.

If the AF is not authorized to provide parameters, then NEF indicates the reason for the failure in an Nnef_ParameterProvisionCreateUpdate response message in step 1002. Step 1007 is not performed in this case.

If the NEF does not receive DNN and/or S-NSSAI from the AF and such information is configured as needed in the 5GC, the NEF determines DNN and/or S-NSSAI from the AF identifier.

Step 1003: corresponding subscription information can be read from the UDR by nudr_dm_query to verify the required data updates and authorize the modification of these parameters for this subscriber or corresponding AF group.

Step 1004: if the UDM authorizes the AF to provide parameters to the subscriber, the UDM parses the GPSI into SUPI and requests creation, update or deletion of the provided parameters as part of the subscription data via a Nudr_DM_Create/Update Request message. The message includes the provided parameters.

If a new 5G VN group is created, the UDM should assign a unique internal group ID to the 5G VN group and include the newly assigned internal group ID in the Nudr_DM_CreateRequest message. If the list of 5G VN group members changes or the 5G VN group data changes, the UDM updates the UE and/or the UE group subscription data according to the AF/NEF request.

The UDR stores the provided parameters as part of the UE and/or UE group subscription data and responds with a nudr_dm_create/Update Response message.

When 5G VN group data is updated, the UDR notifies the subscribing PCF by sending nudr_dm_notify.

If the AF is not authorized to provide parameters, the UDM proceeds to step 1005, indicates the reason for the failure in a Nudm_ParameterProvision_update response message, and does not perform step 1007.

The UDM classifies received parameters (e.g., expected UE behavior parameters, including UE status information) as AMF related parameters and/or SMF related parameters. The UDM may use the AF identifier received from the NEF in step 1002 to associate the received parameters with the particular subscribed DNN and/or S-nsai. The UDM stores the SMF related parameters under the corresponding session management subscription data type.

Each parameter or set of parameters may be associated with a validity time. The validity times are stored in the UDM/UDR and each NF, to which parameters are provided (e.g., in the AMF or SMF). When the validity period expires, each node automatically deletes the parameters without explicit signaling.

1005: the UDM responds to the request using nudm_parameterProvisions_Create Response, nudm_parameterProvisions_update Response, or nudm_parameterProvisions_Deleteresponse. If the process fails, the cause value is used to indicate the cause.

1006: the NEF responds to the request using an Nnef_ParameterProvisionCreatResponse, an Nnef_ParameterProvisionUpdate Response, an Nnef_ParameterProvisionDeleteResponse. If the process fails, the cause value is used to indicate the cause.

1007: the UDM informs the subscribed network functions (e.g., AMF) of updated UE and/or UE group subscription data via a nudm_sdm_ Notification Notify message. (this step is performed only after step 1004 is successful).

a) If NF is an AMF, the UDM performs nudm_SDM_Notification (SUPI or internal group identifier (Internal Group Identifier), AMF-associated parameters (including: UE status information), subscription periodic registration timer (Subscribed Periodic Registration Timer), subscription activation time (subscribed Active Time), etc.) service operations. The AMF identifies whether there are overlapping parameter sets and merges the parameter sets in the expected UE behavior if necessary. The AMF uses the received parameters to derive appropriate UE configurations for NAS parameters and to derive core network assisted RAN parameters. The AMF may determine the registration area based on a parameter fixed indicator (Stationary indicator) or an expected UE movement trajectory (Expected UE Moving Trajectory).

b) If NF is SMF, UDM performs nudm_SDM_Notification (SUPI or internal group identifier (Internal Group Identifier), SMF-associated parameter (including UE status information) set, DNN/S-NSSAI, suggested downlink packet count (Suggested Number of Downlink Packets), etc.) service operation.

The SMF stores the received parameters (including UE status information) and associates them with the PDU session according to the DNN and S-nsai contained in the message from the UDM.

The SMF identifies whether there is an overlapping set of parameters in the expected UE behaviour and merges the parameter sets if necessary. SMF may use the following parameters:

the SMF may derive the SMF derived CN assisted RAN information for the PDU session. As described in the PDU session establishment procedure or the PDU session modification procedure, the SMF provides the SMF-derived CN assisted RAN information to the AMF.

The expected UE behavior parameters characterize the expected behavior of a UE or a group of UEs. The set of these UE behavior parameters may be provided by the NEF for storage as part of the UE data.

UE state information is stored in the UDM after being acquired; the SMF or AMF subscribes by subscribing to UDM events (UE state information events).

The expected UE behavior parameters, e.g., UE state information, may be stored as AMF-related expected UE behavior parameters (UE levels) and SMF-related expected UE behavior parameters (PDU levels), respectively, within the UDM (i.e., UE level information stored as AMF-related expected UE behavior parameters; PDU level information stored as SMF-related expected UE behavior parameters, respectively

The SMF retrieves from the UDM the expected UE behavior parameters associated with the SMF of the particular PDU session.

The expected UE behavior parameters may be specified as shown in table 1.

Example two,

The AMF may send the UE status information to the access network function in an N2 message.

The manner in which the AMF obtains the UE status information may include at least one of: acquiring from the UE in a registration procedure; the AF is sent to the UDM through the NEF as in example 2, from which the AMF is acquired.

The UE status information may be carried in UE5G mobility management core network capability (UE 5GMM Core Network Capability), provided to the network in a UE registration flow procedure, and the network may perform policy decisions and enforcement on XRM services according to the UE status information.

As shown in fig. 11, in the UE registration procedure, the UE sends the UE status information to the AMF in 5GMM Core Network Capability, and the specific steps of sending the UE status information to the access network function by the AMF include:

step 1101: the UE sends a registration request message to the (R) AN, where the registration request carries UE5G mobility management core network capabilities (UE 5GMM Core Network Capability), including capability support for UE state information in the UE5G mobility management core network capabilities.

The AN message sent by the UE to the access network function may include: AN parameters, registration request (registration type, suior 5G-GUTI or PEI, [ TAI last visited (if available) ], security parameters, [ request nsai ], [ request nsai mapping ], [ nsai indication of default configuration ], [ UE air interface capability update ], [ UE mobility management core network capability ], … …).

If the UE supports sending the UE status information, the UE carries the UE status information in a registration request (e.g. UE mobility management core network capability indicates the UE status information).

To ensure that the UE MM core network capabilities stored in the AMF are up to date, the UE should send UE MM core network capability information to the AMF during initial registration and mobility registration update in NAS messages.

Step 1103: the access network function selects a corresponding AMF, forwards the registration request of the UE to the AMF, and the registration request in step 1101 is carried in an N2 message. The AMF stores the corresponding UE MM Core Network Capability into the UE context. If the UE provides UE status information in step 1101, the AMF stores the UE status information (e.g., to the UE context).

The AMF checks the event subscription (and or in combination with subscription data and local policy) to see if subscription event reporting is performed. For example, if a UE status update implementation is subscribed to, it is confirmed whether a subscription reporting condition (e.g., UE status change, various thresholds are reached, or power mode is matched or changed, or immediate reporting is received, or periodic reporting, etc.) is satisfied, and notification (notify) reporting is performed according to subscription and reporting requirements.

The access network functions to the New AMF (New AMF) an N2 message (N2 parameter, registration request (step 1101).

The AMF should always store the latest UE MM Core Network Capability received from the UE. When the UE provides registration signaling to UE MM Core Network Capability, any UE MM Core Network Capability the AMF receives from the old AMF/MME is replaced.

Step 1116: optionally, the new AMF performs AM Policy Association setup/modification. If the subscription information contains a UE status information providing requirement, the AMF provides the UE status information to the PCF.

Or the PCF subscribes to the UE status information from the AMF, the AMF performs triggered reporting according to the reporting conditions of the subscription event (e.g., UE status change, various thresholds are reached, or power mode matches or changes, or immediate reporting is received, or periodic reporting is performed, etc.).

Step 1121: the AMF sends the UE status information to the NG-RAN in an N2 message.

Step 1121b: optionally, the new AMF performs UE policy association establishment.

The new AMF sends an npcf_uepolicy control creation request to the PCF. The PCF sends an npcf_uepolicy control creation response to the new AMF.

If the subscription information contains a UE status information providing requirement, the AMF provides the UE status information to the PCF. Or the PCF subscribes to the UE status information from the AMF, the AMF performs triggered reporting according to the reporting conditions of the subscription event (e.g., UE status changes, various thresholds arrive, or power mode matches or changes, or immediate reporting is received, or periodic reporting, etc.). If the context is the UE migration context, after subscribing to the old AMF, the PCF performs trigger reporting after subscribing to the new AMF before the event. Here, the old AMF is an AMF registered before the UE registers with the new AMF.

Alternatively, the PCF may perform UE policy updates based on the received UE status information. And issuing the updated UE strategy to the AMF and the UE.

Example III,

The AMF uses the NGAP procedure to send UE status information to the access network function.

The access network function stores the information in the UE context. Based on this information, the access network function determines QOS policies of the UE, etc.
