Abstract: Examples pertaining to improvement to signaling over satellite access in mobile communications are described. A user equipment (UE) initiates a procedure with a cell of a network over a satellite access. In response, the UE receives a message from the network indicating that the procedure cannot be completed due to an aspect of the satellite access. Then, the UE reattempts to complete the procedure responsive to a condition being met.

Abstract: Examples pertaining to selection of a tracking area identifier (TAI) as a last visited registered TAI in a geographical location in mobile communications are described. A user equipment (UE) receives broadcast information from a network indicating a plurality of tracking area codes (TACs) for the network. The UE then determines one or more candidate TACs, including at least a first TAC, best representing a current geographical location of the UE from the plurality of TACs received by removing zero, one or more TACs of the plurality of TACs from consideration based on the broadcast information received over time.

Abstract: A method of connection establishment for UE-to-UE relay in a cellular communication system is proposed. A sidelink interface is used for two remote UEs to communicate directly with a relay UE, and in which the relay UE forwards communications between the remote UEs to allow end-to-end communication between the remote UEs. In one embodiment, a first remote UE initiates a single Direct Communication (DC) Request that triggers the establishment of multiple connections between the first remote UE and the relay UE, and between a second remote UE and the relay UE, such that end-to-end relayed transport is available between the first and second remote UE, with hop-by-hop security. The first and second remote UE can make use of the end-to-end relayed transport to authenticate and establish end-to-end secured connection.

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: Various examples pertaining to reflective quality of service (QoS) control in wireless communications are described. A user equipment (UE) receives from a wireless network control signaling that activates support of reflective QoS by the UE. The UE determines whether a predefined condition exists. The UE then indicates to the wireless network a change in a capability of the UE to support the reflective QoS responsive to the determining indicating that the predefined condition exists. When the UE receives from the wireless network control signaling that activates support of reflective QoS by the UE, the UE deletes one or more UE-derived QoS rules among a plurality of active UE-derived QoS rules each with a respective reflective QoS (RQ) timer running.

Abstract: A generic access control procedure is proposed. Every action that is subject to access control is associated with an access category, and each access category is in turn associated with a set of access control parameters. From the APP layer, a UE detects an action that is subject to access control. The UE obtains and stores access categorization rules. In NAS layer, the UE determines the access category for the action. The UE then determines the set of access control parameters for the action. In AS layer, the UE finally applies the set of access control parameters to the action and makes a barring decision for the action. By defining a generic access control procedure and separating access control functions into NAS layer and AS layer, the generic access control is simplified and extendible.

The mapping module can be configured to obtain a second set of target bearers based on resources allocated to the first set of target bearers by the target network system and to obtain a third set of target bearers that is based on the first and second set of target bearers.

Abstract: A method, apparatus and computer program product are provided for identifying a closed subscriber group (CSG) cell to a macrocell in an efficient manner such that the identification of the CSG cell requires less signalling between the mobile terminal and the macrocell, thereby either reducing the overall signalling or providing increased capacity for additional measurement reporting by the mobile terminal. Additionally, a method, apparatus and computer program product are provided in which the CSG cell is identified in a more efficient manner in a cell change order, thereby similarly reduce the signalling requirements between a macrocell and a CSG cell.

Abstract: A network-based solution of supporting IP multimedia subsystem (IMS) call setup in a next generation system (5GS) is proposed. During an attach or registration area update procedure, a serving base station sends an indication to a UE indicating whether IMS voice over PS session is supported or not. Upon receipt of the indication that IMS VoPS is supported, the UE triggers an IMS registration procedure. However, when an MO/MT call happens, the network determines that the UE may be in conditions where voice service is not supported because the network is not able to provide a successful IMS VoPS over the current serving cell connected to 5G core network. The network then triggers a RAT change or a EPS fallback procedure such that the UE is handover to a target cell that supports IMS VoPS.

Abstract: Various combinations of these teachings solve dual errors for a user equipment UE checking whether a private cell is allowed when handing over between serving and target cells, where the PLMN and/or list of EPLMNs of the serving and target cells may differ. The serving cell may send a one-bit indication that there is a change in a handover command or a system information SI6 message after which the UE may or may not refrain from reporting new cells until it performs a registration/location area update in the target cell. The target cell may trigger in the UE a registration update then provide the UE with the PLMN of the target cell. The serving cell can provide the PLMN of the target cell in a SI6 message or handover command, which the UE may use in place of or in addition to the PLMN/EPLMN of the serving cell when checking whether a private/closed subscriber group cell is allowed.
