Title: DATA RADIO BEARER RE-ESTABLISHMENT THROTTLE TIMER CUSTOMIZATION
Abstract:
This disclosure relates to techniques for customizing a data radio bearer re-establishment throttle timer for a wireless device. A data radio bearer (DRB) re-establishment throttle timer length may be determined for a first DRB, based at least in part on characteristics of the DRB, such as a packet delay budget for the DRB. It may be determined that radio link failure has occurred for the DRB. An unsuccessful attempt to re-establish the DRB may be performed. A DRB re-establishment throttle timer may be initiated. The determined DRB re-establishment throttle timer length may be used as the length of the DRB re-establishment throttle timer. A subsequent attempt to re-establish the DRB may be performed after expiration of the DRB re-establishment throttle timer.
