Various embodiments implemented on a multi-subscription-capable communication device (e.g., a mobile communication device capable of supporting more than one wireless subscription) enable a data connection for a blanked subscription to be kept alive during transmit (Tx) blanking by ensuring at least one Packet Data Traffic Channel (PDTCH) transmission is sent to the network before the network's counter for PDTCH transmissions expires.

Method to prevent data stalls due to blanking in multi-SIM multi-active devices

Various embodiments provide systems and methods for recovering from a stall on a mobile communication device. A mobile communication device may receive a data block from a network through a communications channel, where the data block has a block sequence number. The mobile communication may determine whether the block sequence number of the data block is within a receive window and increment a stall counter when the block sequence number is outside of the receive window. The mobile communication device may perform an abnormal release from the communications channel when the stall counter reaches a threshold.
