Abstract: Apparatuses, systems, and methods for a dual subscriber identity module (SIM) dual standby (DSDS) capable user equipment (UE) devices to perform data operations with a first SIM that is not capable of or preferred for packet switched (PS) services and a second SIM that is capable of or preferred for PS services. A timer may be initiated upon radio frequency (RF) chain handover from the first SIM to the second SIM, whereupon a first connection associated with the first SIM is maintained in an idle state while the timer is running. Upon expiration of the timer, the UE may determine whether to send a scheduling request to maintain or release the first connection. The timer may be utilized when a call is dropped over the first connection, to increase the likelihood of successfully receiving a callback. The timer may be shortened in duration to reduce reception of spam messaging.

Abstract: A user equipment (UE) that is registered to a stand-alone non-public network (SNPN) can also access services on a public land mobile network (PLMN). The UE accesses the PLMN by transmitting a first signal to a data network, receiving a second signal from the data network in response to the first signal, wherein the second signal identifies a PLMN that is configured to be accessed by the UE via the data network and transmitting a session initiation protocol (SIP) registration request to the PLMN via the data network.

Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN). A UE performs a non-access stratum (NAS) procedure with a public land mobile network (PLMN) of an NTN. The UE receives a NAS message from the PLMN, and the NAS message indicates that the UE is not allowed to access a core network of the NTN. The NAS message may indicate that the UE is not allowed to access the core network of the NTN because a location of the UE is unknown to the NTN, that access to the NTN is not allowed in a country in which the UE is located, or that a location of the UE is not within a country associated with the NTN. The UE modifies its PLMN search procedure responsive to receiving the NAS message.

Abstract: A cellular network includes a first network component configured to i) identify a first session between a first data network and a user equipment (UE), wherein the first session corresponds to a first session management function (SMF), ii) receive data network access information (DNAI) from a network function, the DNAI corresponding to a second data network and iii) select a second SMF that is to be utilized for a second session between the second data network and the UE. The cellular network also includes a second network component configured to i) store a mapping between the DNAI and the second SMF and ii) transmit an indication of the second SMF to the first network component, wherein the first network component selects the second SMF based on the indication.

Abstract: A user equipment (UE) displays a list of available networks for manual network selection. The UE detects multiple networks during a public land mobile network (PLMN) scan, wherein the multiple networks include one or more PLMNs and one or more stand-alone non-public networks (SNPNs), generates a manual network selection list that includes at least i) the one or more PLMNs or ii) the one or more SNPNs, determines a sequence in which entries of the manual network selection list are to be displayed at the UE, displays a graphical user interface (GUI) that includes a representation of the manual network selection list and registers with one of the multiple networks in response to user input.

Abstract: Computer systems and methods are described for operating a network data and analytics function (NWDAF) in a cellular core network. The NWDAF receives user equipment (UE) mobility information from a first network function of the cellular network system and receives edge application server (EAS) information from a second network function of the cellular network system. The NWDAF derives data analytics based at least in part on the UE mobility information and the edge application server information. The NWDAF receives a request for the data analytics from a third network function in the cellular network system, and provides the data analytics to the third network function.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to adaptively manage system information, particularly on-demand system information. A UE may receive mandatory system information from a wireless network and may determine that at least some additional, e.g., on-demand, system information would be beneficial. The UE may evaluate whether a condition is met to request the additional system information and may initiate a random access procedure to request the additional system information. If the random access procedure fails, the UE may adjust its behavior, including reselection behavior, in response to lacking the additional system information.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to avoid invalidation of a subscriber identity module (SIM). A UE may initiate a connection with the network. The network may reject the connection attempt. The UE may selectively determine whether to invalidate the SIM, network, or both. The UE may consider various factors such as details of the connection rejection message, identity of the network, its relationship to the network (e.g., whether the network is a preferred network, etc.), a number of connection rejections received, time remaining on one or more timers, availability of other networks, etc.
