Apple patents smarter data buffering for mobile devices
Apple describes a method for mobile devices to manage how they send data to cell towers. The device checks its internal memory to see how much data is waiting and how important that data is, then adjusts its communication signals accordingly.
In the filing’s own words
A user equipment (UE) may store packet data unit (PDU) sets in a buffer memory. The UE may evaluate a buffer occupancy status of the PDU sets stored in the buffer memory. The UE may determine both the amount of data stored in the buffer memory and the PDU set importance (PSI) for the PDU sets. The UE may alter, based on the PSI parameters, a setting or a transmission occurrence of a random access (RA) procedure, a scheduling request (SR) for a buffer status report (BSR), or a BSR.
What exactly they claim (claim 1)
1. A method for a user equipment (UE), the method comprising: storing data packets in a buffer memory, wherein the data packets correspond to one or more packet data unit (PDU) sets, evaluating a buffer occupancy status of the PDU sets stored on the buffer memory, wherein evaluating the buffer occupancy status comprises: determining an amount of the data packets stored in the buffer memory, and identifying PDU set importance (PSI) parameters for the PDU sets, wherein the PSI parameters indicate a level of importance of the PDU sets; generating a buffer status report (BSR) including information regarding the buffer occupancy status; altering, based on the buffer occupancy status including the PSI parameters, a setting or a transmission occurrence of a random access (RA) procedure corresponding to a scheduling request (SR) for the BSR, the SR for the BSR, or the BSR; and sending, to a network node, a RA preamble, the SR, or the BSR.
