    Abstract: Apparatuses, systems, and methods for performing network slice quota management. A network slice quota management function may store capacity information for one or more network slices. The network slice quota management function may receive a request for an indication of whether a network slice has additional capacity. The network slice quota management function may provide an indication of whether the network slice has additional capacity in response to the request. The capacity information may relate to the capacity of the network slice with respect to the number of wireless devices registered for the network slice, or to the capacity of the network slice with respect to the number of packet sessions established with the network slice, or both, among various possibilities.

    Abstract: This disclosure relates to techniques for a wireless device to re-establish a packet data network connection. The wireless device may establish a packet data network connection via a cellular link with a cellular base station. Information identifying a bearer associated with the packet data network connection may be stored by the wireless device. The wireless device may determine whether the bearer associated with the packet data network connection is active. The packet data network connection may be released by the wireless device and the wireless device may attempt to re-establish the packet data network connection if the bearer associated with the packet data network connection is determined to not be active.

    Abstract: Several techniques using a network slice quota (NSQ) management function 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. In one technique, when the limit is reached, the session aggregated maximum bit rates (AMBR) per subscription level is adjusted in proportionate ratio of the maximum bit rate per subscription level per user equipment (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. In a further technique, when the limit is reached, there is a proportionate equivalent increment and decrement of slice resources based on usage patterns. In yet another technique, a quota update is attempted using the Unified Data Repository (UDR).

    IPC: H04W28/02

    Abstract: A cellular communications system may include a user equipment (UE) that executes a target and non-target applications. The UE may convey a first stream of non-quality-of-service (QoS) wireless data with a first external device over a first Transmission Control Protocol (TCP) session and may receive a second stream of non-QoS wireless data from a second external device over a second TCP session. Responsive to a drop in data rate of the first stream, the UE may perform mitigation operations that adjust receipt of the second stream to boost the data rate of the first stream. The mitigation operations may include transmission of a triple duplicate acknowledgement (TDA), delayed transmission of an acknowledgment (ACK) to the second stream, and/or terminating the second TCP session. This may prevent disruptions to user experience with the first software application even when the network has downlink data to transmit to the UE.
