Abstract: A method to establish and activate an MA PDU session for data transmission over a selected access is proposed. UE initiates a UE-requested PDU session establishment procedure. Once the UE receives a PDU SESSION ESTABLISHMENT ACCEPT message with ATSSS container IE, the UE can consider the MA PDU session has been activated and user plane resources are successfully established on the selected access. A method to convert an SA PDU session to an MA PDU session for data transmission over a selected access is proposed. UE initiates a UE-requested PDU session modification procedure. Once the UE receives a PDU SESSION MODIFICATION COMMAND message with ATSSS container IE, the UE can consider the MA PDU session has been converted from the SA PDU session and user plane resources are successfully established on the selected access.

Abstract: A method for handling updated NPN configuration received via downlink Non-Access Stratum (DL NAS) signaling from a first non-hosting network is provided. In one embodiment, a UE receives an updated CAG related configuration containing one or more CAG(s) associated with (time) validity information. The UE enters the state PLMN-SEARCH and applies a network selection process with the updated CAG related configuration. The UE selects and registers to a second hosting network with one or more CAG(s) included in the updated CAG related configuration and configured with associated (time) validity information, and (time) validity criteria are met.

Abstract: A method for supporting redundant PDU session under intersystem change between 5GS and EPS is proposed. A UE maintains a PDU session that is a redundant PDU session, associated with a PDU session pair ID and/or a redundancy sequence number (RSN). When inter-system change from N1 mode to S1 mode occurs, the PDU session is transferred/mapped to a PDN connection. The UE shall associate the PDU session pair ID and/or the RSN with the PDN connection corresponding to the PDU session (e.g., associate with the default EPS bearer context of the PDN connection). When inter-system change from S1 mode to N1 mode occurs, the PDN connection is transferred/mapped back to the PDU session. The UE shall associate the PDU session pair ID and/or the RSN with the PDU session corresponding to the PDN connection.

Abstract: Aspects of the disclosure provide methods and apparatuses. The method can include receiving, at a user equipment (UE), system information broadcast from a base station which may be shared by one or more PLMNs and SNPNs, the system information including an indication of whether accessing an SNPN using home service provider (HSP) subscription of a HSP network is supported. The UE can be configured with subscription information of the HSP network. The subscription information can include the HSP subscription and a home SP selection list that includes one or more candidate networks each represented by an SNPN identifier. The method can further include responsive to the system information, selecting a network from the home SP selection list according to a priority order of the candidate networks, and accessing the network selected from the home SP selection list using the HSP subscription.

Abstract: A method for handling a collision of a UE-requested MA PDU session release procedure and a network-requested MA PDU session release procedure is proposed. If the Access type IE is included in the PDU SESSION RELEASE COMMAND message, and the PDU session is an MA PDU session and having user-plane resources established on the access different from the access indicated in the Access type IE in the PDU SESSION RELEASE COMMAND message, then the UE proceeds with both the UE-requested PDU session release procedure and network-requested PDU session release procedure. Otherwise, the UE aborts the UE-requested PDU session release procedure and stops the timer T3582 and proceeds with the network-requested PDU session release procedure.

Abstract: A method for handling a collision of a UE-requested MA PDU session establishment procedure and a network-requested MA PDU session release procedure is proposed. If the UE-requested PDU session establishment procedure is to establish user plane resources on a second access type for an MA PDU session on a first access and the Access type IE is not included in the PDU SESSION RELEASE COMMAND or the Access type IE included in the PDU SESSION RELEASE COMMAND indicates the first access, then the UE proceeds with the network-requested PDU session release procedure for releasing the MA PDU session, and aborts the UE-requested PDU session establishment procedure.

Abstract: A method of handling parameters of a subscribed network upon accessing a selected Stand-alone Non-Public Network (SNPN) using credentials from a credential holder is proposed. The UE selects an SNPN using a configured list of subscriber data, e.g., based on SNPN selection parameters contained in a selected entry of the list of subscriber data, or selects the SNPN based on SNPN selection parameters associated with a PLMN subscription of a USIM card. The UE accesses the selected SNPN using credentials supplied by a subscribed network, which is identified by the selected entry or by the USIM card. Upon successful registration to the selected SNPN, the UE applies a list of 3GPP PS_Data_Off exempt services that is different from a configured list of 3GPP PS_Data_Off exempt services associated with the selected entry, and evaluates a URSP that is different from the pre-configured URSP of the subscribed network.

Abstract: A method to facilitate onboarding registration via an onboarding network (ON) that is a stand-alone non-public network (ON-SNPN) is proposed. A UE is preconfigured with default UE credentials for Onboarding. UE discovers and selects an ON-SNPN and registers to the ON-SNPN using default UE credentials. Both user plane (UP) and control plane (CP) provisioning procedure can be used to obtain the SNPN credentials from a subscriber owner (SO) via an ON-SNPN access connectivity. In accordance with one novel aspect, when UE sends a registration request for UE onboarding registration, the registration request comprises information for registration type (e.g., SNPN ONBOARDING), and UE supported provisioning procedure (e.g., CP, UP, or both). Upon successful registration, UE follows the supported provisioning procedure (i.e., CP or UP) decided by the ON-SNPN to obtain the SNPN credentials from the SO-SNPN via the ON-SNPN access connectivity to a Provisioning Server (PVS).

Abstract: A method of enhanced handling of a Forbidden SNPN list by a UE is proposed. When the UE registers to a first SNPN using credentials supplied by a second SNPN and receives a rejection from the network, the UE adds an entry of the first SNPN into one of the forbidden SNPN lists, and also creates an association between the first SNPN and the second SNPN. As a result, the UE is refrained from registering to the first SNPN using the credentials supplied by the second SNPN as long as the first SNPN entry remains in the forbidden SNPN list. However, the UE is allowed to register to the first SNPN using credentials supplied by other SNPNs.
