Abstract: Various embodiments include an automobile network device that includes a descriptor sorting engine (DSE). The DSE may include a direct memory access (DMA) controller, a memory organized by channel clusters that each include a plurality of first-in first-out (FIFO) memories, a timer, and a time stamp (TS) sorting logic component. The DMA controller may be configured to pull timestamp-pointer pairs from packet descriptors stored in an unsorted descriptor ring memory, store the timestamp-pointer pairs in the FIFO memories, trigger the TS sorting logic component to reorder the timestamp-pointer pairs in the FIFO memories so that they are sorted in ascending order, use the sorted timestamp-pointer pairs in the FIFO memories to read the packet descriptors stored in an unsorted descriptor ring memory, and store the packet descriptors in a sorted descriptor ring memory.

Abstract: Allocation failures may occur on a network during handovers. Therefore, a user equipment (UE) may include a configurable timer that is configured to begin once an allocation or grant is revoked or a quality-of-service (QoS) condition is unsatisfied. A UE may be configured to wait for an allocation or grant or may be configured to elicit an allocation or grant. During a network connection, a UE may determine that the allocation or grant is unreceived before expiration of the configurable timer. Based on the determination that the allocation or grant is unreceived before expiration of the configurable timer, the UE may transit a session initiation protocol (SIP) re-invite message in order to allow a network to bring up dedicated bearers for the network connection.
