  • Publication number: 20220232464
    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.

  • Publication number: 20210368395
    Abstract: An approach to provide dynamic adjustment in order to meet the limitation of data rate per network slice in the uplink and downlink wireless connections in a wireless network. The approach uses a network slice quota (NSQ) management function, which keeps track of aggregated maximum bit rates (AMBR) for a slice. Upon reaching a limit, the NSQ functionality dynamically adjusts the user equipment (UE) data rates, reduces the quality of service (QoS), and/or rejects any protocol data unit (PDU) request. Several techniques are described that meet these objectives. In one technique, when the limit is reached, the session AMBR per subscription level is adjusted in proportionate ratio of the maximum bit rate per subscription level per UE. In another technique, when the limit is reached, there is a proportionate equivalent increment and decrement of session AMBR based on usage patterns of the subscription levels.
