Abstract: Methods and apparatus are provided to reduce service interruption for intra-RAT and inter-RAT handover procedures. The UE performs a NAS signaling procedure via a NAS signaling connection in a mobile communication network. The UE monitors a radio resource status and determines whether a radio bearer has been or is being established for a RRC connection for data transmission. The UE determines whether to release the NAS signaling connection after completing the NAS signaling procedure based on whether the radio bearer has been established. In one embodiment, the UE monitors a radio resource status and determines whether a radio bearer has been established for a RRC connection for data transmission. The UE determines whether to start a timer upon completing the NAS signaling procedure based on whether the radio bearer has been or is being established.

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: A method for expedited tunnel establishment with a non-Third Generation Partnership Project (3GPP) interworking gateway to access a 3GPP network is provided. A User Equipment (UE) initiates establishment of an Internet Protocol secure (IPsec) tunnel with a first non-3GPP interworking gateway associated with the 3GPP network. The UE probes availability of a second non-3GPP interworking gateway associated with the 3GPP network before the IPsec tunnel with the first non-3GPP interworking gateway is established successfully. The UE initiates establishment of an IPsec tunnel with the second non-3GPP interworking gateway in response to failing to establish the IPsec tunnel with the first non-3GPP interworking gateway and the second non-3GPP interworking gateway being available. The UE accesses the 3GPP network over the IPsec tunnel with the second non-3GPP interworking gateway.

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: 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 for handling a collision of a UE-requested PDU session establishment procedure and a network-requested PDU session modification procedure is proposed. When a PDU SESSION ESTABLISHMENT REQUEST message indicates that the UE-requested PDU session establishment request procedure is to handover an existing PDU session between 5G 3GPP access and 5G non-3GPP access, UE and NW proceed with the UE-requested PDU session establishment procedure and abort the NW-requested PDU session modification procedure. When a PDU SESSION ESTABLISHMENT REQUEST message indicates that the UE-requested PDU session establishment request procedure is to establish user plane resources for an MA PDU session, UE and NW proceed with both the UE-requested PDU session establishment procedure and the NW-requested PDU session modification procedure.

Abstract: A method of determining paging restriction on downlink signals for MUSIM UEs is proposed. If a UE requests the network to support paging restriction over the first USIM, the UE can send a request message to the network, carrying a UE-preferred paging restriction information. Subsequently, the UE should then receive an accept message from the network that the paging is restricted over the first USIM based on the UE-preferred paging restriction information. As a result, when DL signaling is pending for the UE over the first USIM, the network can determine whether it should page the UE over the first USIM based on the paging restriction type indicated in the paging restriction information. Since the DL signaling is selectively restricted over USIM1, the UE can perform more important jobs over USIM2 with better performance and user experience.

Abstract: A method of handling NAS signaling connection release under mobility management congestion control for MUSIM UE is proposed. A MUSIM UE has established a NAS signaling connection on a first USIM in connected mode. Later on, the MUSIM UE has more important job to be started on the second USIM. The MUSIM UE wishes to initiate a service request procedure by transmitting a service request to the network, to release the NAS signaling connection on the first USIM. However, under the 5GMM/EMM signaling congestion condition with timer T3346 running, the AMF/MME rejects 5GMM/EMM signaling requests from UE. In one novel aspect, the MUSIM UE requests the network to release the NAS signaling connection while timer T3346 is still running. As a result, the MUSIM UE is able to start the more important job on the second USIM, or to improve user experience on the second USIM.
