Apparatuses, systems, and methods for a network to notify user equipment device (UE) whether a network slice the UE has requested is subject to a quota. An AMF of the network may inform the UE if an allowed slice(s) is subject to quota management as part of a registration procedure via a registration accept and/or a UE configuration update command. In addition to providing information regarding whether an S-NSSAI is subject to quota management, the AMF may also share the percent of quota availability to the UE. The UE may implement access control logic based on the received available quota for a particular network slice.

Knowledge of slice quota availability for a UE

Systems and methods are disclosed for de-prioritizing an LTE anchor cell based on NR cell measurements. A UE may register on a first cell of a first Radio Access Technology (RAT), process a configuration message from a network prioritizing an anchor band of the first RAT, perform a first cell reselection from the first cell to a second cell of the first RAT that is in the anchor band, and perform cell measurements on one or more cells of a second RAT. In response to determining that none of the cell measurements for the one or more cells of the second RAT exceeds a threshold, the UE de-prioritizes the second cell in ranked cell prioritization data and performs a second cell reselection from the second cell of the first RAT to another cell of the first RAT based on the ranked cell prioritization data.

A device, system, and method improve a call setup time. The method is performed at a device configured to establish first and second network connections where the second network performs circuit switched voice calls. The method includes receiving a call input to perform a call and determining whether the device is registered with a first feature to perform the call based on an Internet Protocol (IP). When the device is registered with the first feature, the method includes determining whether timeouts for attempting previous IP calls is greater than a threshold. When the timeouts are at least the threshold, the method includes deregistering from the first feature and performing a circuit switched fallback (CSFB) procedure including a handover from the first network to the second network. The method includes performing the call as a circuit switched call.

Call setup time in loaded IMS networks

A device is configured to establish a first roaming network connection to a first roaming network and a second roaming network connection to a second roaming network. The first roaming network has a higher priority than the second roaming network, the second roaming network configured to support a first radio access technology (RAT) and a second RAT, the first RAT having a higher priority than the second RAT. When a current network connection is the second roaming network connection, determining a current RAT used for the second roaming network connection. When the current RAT is the first RAT, determining between an active use state and a non-active use state. When the device is in the active use state, deactivating a capability to reselect to the first roaming network.
