[0066] The following first describes the relevant technologies of this application.

[0067] Referring to FIG. 2 , a method for controlling network access in related art includes the following steps:

[0068] Step 1: AMF determines whether to perform number of UEs per network slice availability check and update based on the trigger.

[0069] If the AMF does not know which Network Slice Admission Control Function (NSACF) to communicate with, the AMF performs NSACF discovery.

[0070] The triggering event of the trigger may include:

[0071] The network slices subject to Network Slice Admission Control (NSAC) are included in the allowed Network Slice Selection Assistance Information (NSSAI) (i.e. the AMF requests the UE to register with the network slice identified by the S-NSSAI);

[0072] The network slice subject to NSAC (Network Slice Admission Control) is removed from the allowed NSSAI (i.e. the AMF requests the UE to be deregistered from the network slice identified by the S-NSSAI);

[0073] Changes in NSSAI are permitted in case of inter-AMF migration.

[0074] The availability check and update of the number of UEs performing the network slice are triggered by the following process:

[0075] 1) During the UE registration procedure (including registration types of initial registration or mobility registration update in inter-AMF mobility in the Connectivity Management - Connected (CM-CONNECTED) or Connectivity Management - Idle (CM-IDLE) states):

[0076] If Early Access Control (EAC) mode is active, before registration acceptance;

[0077] If EAC mode is not activated, then after the registration acceptance message;

[0078] In the UE deregistration procedure, after the deregistration process is completed.

[0079] 2) During the UE configuration update procedure (which may be caused by the Network Slice-Specific Authentication and Authorization (NSSAA) procedure or the change of the network slice identified by the subscribed S-NSSAI):

[0080] If EAC mode is active and the update flag indicates to increase the number of UEs registered to the network slice identified by S-NSSAI, before the UE configuration update message;

[0081] If EAC mode is active and the update flag indicates to reduce the number of UEs registered to the network slice identified by S-NSSAI, then after the UE Configuration Update message;

[0082] If EAC mode is not activated, then after UE Configuration Update message.

[0083] It should be noted that network slices identified by different S-NSSAI may have different NSACFs, so during registration, the AMF will trigger the UE quantity availability check and update process of the network slice to multiple NSACFs.

[0084] Step 2: AMF sends Nnsacf_NSAC_NumOfUEsUpdate_Request message to NSACF. AMF includes UE identity (ID), access type to which allowed NSSAI is applied, S-NSSAI(s), network function (NF) ID and update flag in the message, where the update flag indicates whether to increase the number of UEs registered to the network slice identified by S-NSSAI(s). Increase the number of UEs registered to the network slice identified by S-NSSAI when the UE is registered to the network slice constrained by NSAC, or reduce the number of UEs registered to the network slice identified by S-NSSAI when the UE deregisters from the network slice identified by S-NSSAI, or reduce the number of UEs registered to the network slice identified by S-NSSAI if the registration of a network slice identified by S-NSSAI cannot be updated.

[0085] If this is the first time that the NSAC procedure for the network slice identified by the S-NSSAI is performed towards the NSACF, the AMF includes the notification endpoint for EAC notification to implicitly subscribe to EAC notification for the network slice identified by the S-NSSAI from the NSACF.

[0086] Step 3: NSACF performs availability check and update of the number of UEs in the network slice.

[0087] Based on its configuration, the NSACF determines whether the Access Type provided by the AMF is configured for the NSAC. If the Access Type is not configured for the NSAC, the NSACF always accepts requests from the AMF without increasing or decreasing the number of UEs. If the Access Type is configured for the NSAC, the NSACF updates the number of UEs currently registered for the network slice identified by the S-NSSAI based on the information provided by the AMF in the Update Flag parameter, i.e., increases or decreases the number of UEs registered for the network slice.

[0088] If the Update Flags parameter from the AMF indicates an increase, the following applies:

[0089] If the UE ID is already in the list of UEs registered with the network slice, the current number of UEs will not be increased because the UE is already registered with the network slice. NSACF creates a new entry associated with this new update and should also maintain the old entry associated with the previous update. Multiple entries for the same UE ID in NSACF are distinguished based on the NF ID of the NF sending the update request. NSACF deletes the entry associated with the NF ID when it receives a request with an update flag indicating a decrease in the number of UEs.

[0090] NOTE: The use cases where the same UE has two or more entries in the NSACF may occur during (a) inter-AMF mobility when the new AMF requests an update to the NSACF before the old AMF sends a request to deregister the UE; or (b) when multiple SMFs + Packet Data Network Gateway Control Plane (PGW-C) (i.e., for different Public Data Network (PDN) connections associated with the same S-NSSAI identified network slice) send an update request for the maximum number of UEs to the NSACF to establish PDN connections in the Evolved Packet Core (EPC).

[0091] NOTE: To handle AMF smooth deletion, NSACF may subscribe to unavailability notifications from AMF (directly or through NRF) and take corresponding actions, such as updating NF ID with the target AMF ID.

[0092] If the UE ID is not in the list of UE IDs registered with the network slice and the maximum number of UEs registered with the network slice has not been reached, the NSACF adds the UE ID to the list of UEs registered with the network slice as a new entry associated with this new update and increases the number of UEs registered with the network slice. If the UE ID is not in the list of UE IDs registered with the network slice identified by the S-NSSAI and the maximum number of UEs registered with the network slice identified by the S-NSSAI has been reached, the NSACF returns a result parameter indicating that the maximum number of UEs registered with the network slice identified by the S-NSSAI has been reached.

[0093] If the Update Flag parameter from the AMF indicates a decrease and if there is only one entry associated with the UE ID, the NSACF removes the UE ID from the UE list for each network slice identified by the S-NSSAI registered to the network slice. If there are multiple entries associated with the UE ID, the NSACF removes the entry associated with the NF ID but the UE ID remains in the UE list registered to the network slice identified by the S-NSSAI.

[0094] NSACF takes the access type into account to increase and decrease the number of UEs per network slice.

[0095] If an EAC notification associated with a network slice identified by S-NSSAI is received from the AMF, the NSACF stores the notification endpoint. The NSACF can use this AMF notification endpoint to update the EAC mode.

[0096] NOTE: This enables the NSACF to maintain up-to-date information about the AMFs serving the network slice identified by the S-NSSAI.

[0097] Step 4: NSACF returns the Nnsacf_NSAC_NumOfUEsUpdate_Response message, including the result indication of the network slice identified by S-NSSAI, where the result indication includes "the maximum number of UEs registered with the network slice has been reached" or "the maximum number of UEs registered with the network slice has not been reached".

[0098] During the UE registration procedure, if only some of the network slices identified by the S-NSSAI reach the maximum number of UEs, the AMF shall send a Registration Accept message to the UE, where the AMF includes the rejected network slices identified by the S-NSSAI in the RejectedNSSAI parameter. For each rejected network slice identified by the S-NSSAI, the AMF shall include a Reject Cause set to the "maximum number of UEs in the network slice reached" and optionally return the shutdown timer.

[0099] When the maximum number of UEs per network slice returned by the NSACF has been reached for all requested S-NSSAI identified network slices provided in step 2, and if one or more subscribed S-NSSAI identified network slices are marked as not subject to NSAC by default in the subscription data, the AMF may decide to include these default subscribed S-NSSAI identified network slices in the allowed NSSAI. Otherwise, the AMF rejects the UE's registration request and includes the rejected S-NSSAI identified network slices in the rejected NSSAI parameter in the Registration Reject message, and for each rejected S-NSSAI identified network slice, the AMF includes the rejection cause to indicate that the maximum number of UEs per network slice has been reached and an optional back-off timer.

[0100] Note: If the use case requires that the UE always remain reachable through at least one network slice, it is recommended to mark at least one of the subscribed S-NSSAI identified network slices as the default S-NSSAI identified network slice that is not subject to NSAC. This will ensure that the UE can access the service even if the maximum number of UEs per network slice has been reached.

[0101] Please refer to Figure 3. For the control of the number of PDU sessions in the network slice, please refer to the process of controlling the number of UEs in the above-mentioned network slice, and no further description will be given.

[0273] The following describes the network access control method of the present application with examples in conjunction with specific application scenarios.

[0274] Example 1 of this application:

[0275] In an embodiment of the present application, NSACF serves as the above-mentioned first device, and signs an energy usage value of OAM or NWDAF or EECF or EENF. When the energy usage value of a network slice exceeds the maximum energy value of the network slice (i.e., the maximum energy credit limit), NSACF is notified, and NSACF performs a first operation, which is a network slice admission or access control related operation.

[0276] In this embodiment, the energy usage value of the network slice is taken as an example for illustration. In some other embodiments, it can also be replaced by at least one of the energy usage value, energy consumption value and energy efficiency value of the network slice.

[0277] Referring to FIG8 , the network access control method of the first embodiment of the present application includes:

[0278] Step 0: OAM or NWDAF or EECF or EENF generates (or monitors or calculates) the energy usage value of the network slice.

[0279] NSACF pre-configures the maximum energy usage value of the network slice, that is, the maximum energy credit limit.

[0280] The network slice may be a certain network slice, or one or more network slices corresponding to a certain application.

[0281] In this embodiment of the present application, optionally, the maximum energy usage value of the network slice satisfies at least one of the following:

[0282] The maximum energy usage value of the network slice is the maximum energy usage value within the target time; that is, the maximum energy usage value of the network slice takes effect within the target time. Optionally, the target time may include at least one of the following: an effective start time and an effective end time.

[0283] The maximum energy usage value of the network slice is the maximum energy usage value of the target area.

[0284] Steps 1-1, 1-2, 1-3: NSACF sends a first request (energy usage subscribe request) to OAM or NWDAF or EECF or EENF, where the first request is used to request OAM or NWDAF or EECF or EENF to provide notification information, where the notification information is whether the energy usage value of the network slice reaches the maximum energy credit limit.

[0285] The first request sent by the NSACF includes at least one of the following:

[0286] A reporting type, the reporting type including at least one of periodic reporting and single reporting;

[0287] Reporting trigger condition; the reporting trigger condition is, for example, a trigger threshold, and reporting is performed when the trigger threshold is reached.

[0288] Reporting time;

[0289] Reporting area.

[0290] Optionally, the reporting time may include at least one of a reporting start time and a reporting end time.

[0291] Steps 2-1, 2-2, and 2-3: The OAM or NWDAF or EECF or EENF sends a response (energy usage subscribe response) to the NSACF.

[0292] Steps 3-1, 3-2, 3-3: OAM or NWDAF or EECF or EENF sends notification information to NSACF on demand, and the notification information indicates whether the energy usage value of the network slice reaches the maximum energy credit limit.

[0293] Step 4: AMF / SMF triggers the availability check and update of the number of users / terminals or PDU sessions of the network slice.

[0294] Step 5: AMF / SMF sends the above-mentioned second request (Nnsacf_NSAC_NumOfUEsUpdate_Request or Nnsacf_NSAC_NumOfPDUsUpdate_Request), which is used to request to update the number of network slice users / terminals or the number of network slice PDU sessions or to perform network slice access or admission control or to update the energy usage value or energy consumption value or energy efficiency value of the network slice.

[0295] Step 6: NSACF performs availability check and update of the number of users / terminals or PDU sessions of the network slice, that is, based on the above notification information, performs the above first operation.

[0296] Step 7: NSACF sends a second response (Nnsacf_NSAC_NumOfUEsUpdate_Response or Nnsacf_NSAC_NumOfPDUsUpdate_Response) to AMF / SMF, wherein the second response indicates whether the current energy usage value of the network slice reaches the maximum energy usage value of the network slice.

[0297] If the current energy usage value of the network slice reaches the maximum energy usage value of the network slice, NSACF returns a result parameter indicating that the current energy usage value of the network slice reaches the maximum energy usage value of the network slice.

[0298] After receiving the second response, the AMF or SMF sends a response to the terminal, where the response includes first indication information, and the first indication information indicates whether the network slice allows terminal access or PDU session establishment.

[0299] If the second response indicates that the current energy usage value of the network slice does not reach the maximum energy usage value of the network slice, the first indication information indicates that the network slice allows terminal access or PDU session establishment;

[0300] If the second response indicates that the current energy usage value of the network slice reaches the maximum energy usage value of the network slice, the first indication information instructs the network slice to reject terminal access or PDU session establishment.

[0301] If the first indication information indicates that the network slice rejects terminal access or PDU session establishment, the response also includes a rejection reason, and the rejection reason is that the current energy usage value of the network slice reaches the maximum energy usage value of the network slice.

[0302] For example, if some network slices identified by S-NSSAI reach the maximum energy usage value, the AMF sends a registration acceptance message (response) to the UE, and the registration acceptance message (response) includes the rejected network slices identified by S-NSSAI, and the rejected network slices identified by S-NSSAI include the rejected network slices identified by S-NSSAI. The registration acceptance message (response) may also include the reason for rejection: the energy usage value of the network slice reaches the maximum energy usage value of the network slice.

[0303] Alternatively, the SMF sends a rejection message to the UE to reject the PDU session establishment request, and the rejection message includes the rejection reason: the energy usage value of the network slice reaches the maximum energy usage value of the network slice.

[0304] Example 2 of this application:

[0305] In embodiment one, OAM or EECF or EENF or NWDAF notifies NSACF when the energy usage value of the network slice exceeds the maximum energy value of the network slice (i.e., the maximum energy credit limit), and NSACF performs a first operation, which is a network slice admission or access control related operation.

[0306] In this embodiment, OAM or EECF or EENF or NWDAF directly provides the energy usage value of the network slice to NSACF, and NSACF determines whether the energy usage value of the network slice reaches the maximum energy usage value of the network slice.

[0307] In this embodiment, the energy usage value of the network slice is taken as an example for illustration. In some other embodiments, it can also be replaced by at least one of the energy usage value, energy consumption value and energy efficiency value of the network slice.

[0308] Referring to FIG. 9 , the network access control method of this embodiment includes:

[0309] Step 0: OAM or EECF or EENF or NWDAF generates (or monitors or calculates) the energy usage value of the network slice.

[0310] NSACF pre-configures the maximum energy usage value of the network slice.

[0311] The network slice may be a certain network slice, or one or more network slices corresponding to a certain application.

[0312] In this embodiment of the present application, optionally, the maximum energy usage value of the network slice satisfies at least one of the following:

[0313] The maximum energy usage value of the network slice is the maximum energy usage value within the target time; that is, the maximum energy usage value of the network slice takes effect within the target time. Optionally, the target time may include at least one of the following: an effective start time and an effective end time.

[0314] The maximum energy usage value of the network slice is the maximum energy usage value of the target area.

[0315] Steps 1-1, 1-2, 1-3: NSACF sends a first request (energy usage subscribe request) to OAM or NWDAF or EECF or EENF, where the first request is used to request the energy usage value of the network slice.

[0316] The first request sent by the NSACF includes at least one of the following:

[0317] A reporting type, the reporting type including at least one of periodic reporting and single reporting;

[0318] Reporting trigger condition; the reporting trigger condition is, for example, a trigger threshold, and reporting is performed when the trigger threshold is reached.

[0319] Reporting time;

[0320] Reporting area.

[0321] Optionally, the reporting time may include at least one of a reporting start time and a reporting end time.

[0322] Steps 2-1, 2-2, and 2-3: The OAM or NWDAF or EECF or EENF sends a response (energy usage subscribe response) to the NSACF.

[0323] Steps 3-1, 3-2, and 3-3: OAM or NWDAF or EECF or EENF reports the energy usage value of the network slice on demand.

[0324] Step 4: NSACF determines whether the energy usage value of the network slice reaches the maximum energy usage value.

[0325] Step 5: When the energy usage value of the network slice reaches the maximum energy usage value, NSACF sends an analysis or prediction request to NWDAF, such as energy related analysis.

[0326] The analysis or prediction request is used to request NWDAF to return at least one of the updated maximum energy usage value, maximum energy consumption value, maximum energy efficiency value, maximum number of registered users / terminals, and maximum number of PDU sessions of the network slice.

[0327] The analysis or prediction request may carry at least one of the following information: S-NSSAI, energy usage value of the network slice, subscription content, and the subscription content may include, for example: the maximum number of users / terminals subscribed to the network slice, the number of PDU sessions subscribed to the network slice, the maximum energy usage value or maximum energy efficiency value or maximum energy consumption value of the subscribed network slice.
