Abstract: Various solutions for enhancing quality of service (QoS) based on environmental conservation in mobile communications are described. An apparatus may determine whether an eco-friendly condition associated with a data session is met. Also, the apparatus may determine to modify a QoS associated with the data session in an event that the eco-friendly condition associated with the data session is met.

Abstract: A method supporting enhanced network identity (NID) provisioning under User Equipment (UE) mobility scenarios between different types of networks is proposed. When a UE registers to an SNPN, the UE is assigned with a 5G-GUTI by the SNPN. The SNPN is identified by an SNPN ID==PLMN ID+NID. When the UE moves from the SNPN to another target network having a target AMF, the UE triggers a mobility registration update procedure and provides the 5G-GUTI along with NID information in a Registration Request to the target AMF. The target AMF can use the NID information along with the 5G-GUTI to find a source AMF for deriving UE context for the subsequent operations during the mobility registration update procedure. Providing NID information along with 5G-GUTI can assist the target AMF to find the source AMF efficiently, preventing a potential registration procedure failure.

Abstract: Various solutions for enhancements on automatic stand-alone non-public network (SNPN) selection for supporting localized services are described. An apparatus may determine whether it supports accessing an SNPN providing access for localized services and a user enables to access localized services. Responsive to determining that it supports accessing an SNPN providing access for localized services and the user enables to access localized services, the apparatus may select an available SNPN with validity information in an event that both the apparatus and the selected available SNPN support access using credentials from a credentials holder (CH) and the validity information is met, and then attempt a registration on the selected SNPN.

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.

Abstract: A method of reducing gray energy consumption and achieving optimal gray energy saving for carbon neutralization is proposed. In a cellular network, each cell or BS (group of cells) has renewable (green) and non-renewable (gray, on-grid power) energy sources. The renewable (green) energy is highly variable and unpredictable, while non-renewable (gray, on-grid power) is stable but is not renewable and thus has more carbon impact. Each cell or BS (group of cells) services is associated UEs when it is on. In one novel aspect, a cell or BS (group of cells) that consumes more non-renewable energy can give some or all of its served UEs to another cell or BS (group of cells) that consumes less non-renewable energy.

Abstract: In accordance with one novel aspect, a method of handling updated a CAG related configuration and in response perform a NAS procedure for releasing NAS connection is proposed. While camping on a CAG cell, during a NAS procedure, a UE receives a DL NAS message from AMF that carries validity or restriction information associated with a CAG-ID for the current PLMN and the CAG-ID is supported by the current CAG cell and included in the DL NAS message, and the validity or restriction criteria are not met according to the validity or restriction information. The UE starts a timer to allow the AMF to release the NAS connection. The UE locally releases the NAS connection upon timer expiry.

Abstract: A method of UE autonomously updating a CAG related configuration upon receiving a downlink NAS message is provided. If a CAG-ID is included in an allowed CAG-IDs list of the CAG related configuration and is supported by a CAG cell in a PLMN, then UE may attempt to access the CAG cell in the PLMN. If the access is denied, e.g., UE receives a DL NAS message with a cause value, then UE needs to update the CAG related configuration. If the CAG-ID is not associated with any validity or restriction information, then the CAG-ID should be deleted from the CAG related configuration. If the CAG-ID is associated with validity or restriction information and corresponding validity or restriction criteria are not met, then the CAG-ID should not be deleted from the CAG related configuration.

Abstract: A method for UE route selection policy (URSP) rule matching enhancement for MA PDU session with 4G PDN leg is proposed. When an application is executed, the upper layer of a UE sends the application information to URSP entity for matching a URSP rule. The UE selects and evaluates a route selection descriptor (RSD) from a list of RSDs of a selected URSP rule to be matched with a PDU session. In one example, the PDU session is an MA PDU session with a 3GPP EPS/PDN leg (PDN connection established as user plane resources of the MA PDU session). The UE finds the traffic descriptor in a selected URSP rule matching the application and an existing MA PDU session/PDN connection matching an RSD of the selected URSP rule, when the UE-requested PDN parameters of the PDN connection matches with the RSD of the selected URSP rule.

Abstract: A method of forbidden SNPN list handling for localized services is provided. In a first embodiment, an original forbidden SNPN list is maintained and is applicable for SNPN/GIN without validity information, and a new forbidden SNPN list is maintained and is applicable for SNPN/GIN with validity information for localized services. If a selected SNPN is associated with validity information, then UE checks whether the selected SNPN belongs to the new forbidden SNPN list. In a second embodiment, the original forbidden SNPN list is maintained and is extended with optional localized service Flag/Indication. Each entry in the original forbidden SNPN list can be associated with an optional localized service Flag or Indication. If a selected SNPN is associated with validity information, then UE checks whether the selected SNPN belongs to the original forbidden SNPN list with a localized service Flag/Indication.

Abstract: A method of enhanced manual network selection procedure for access localized services in PNI-NPN is proposed. For manual CAG/PNI-NPN selection as hosting network, if a CAG cell in a PLMN broadcasting a CAG-ID is available and included in the (Allowed) CAG-ID list of the UE-stored CAG related configuration of the PLMN, the user may manually select the CAG cell as a suitable cell. However, the CAG-ID that is associated with validity information, and the corresponding validity criteria may or may not be satisfied, e.g., due to the UE-stored CAG related configuration is different from the NW-maintained CAG related configuration. Therefore, the UE does not know whether the CAG cell is suitable. In response, the UE triggers a registration procedure for mobility and periodic registration update, and obtains the updated CAG related configuration.
