Method, apparatus and computer program product for providing ciphering problem recovery for unacknowledged mode radio bearer
First Claim
1. An apparatus comprising a processor and a memory storing executable instructions that in response to execution by the processor cause the apparatus to at least perform the following:
- cause a message to be provided indicative of a data reception error has occurred with respect to reception of unacknowledged mode messages, wherein causing the message to be provided comprises causing a particular value to be provided to enable resynchronization of a transmitter of the unacknowledged mode messages with a receiver of the unacknowledged mode messages;
receive a confirmation message including an initialization value based on the particular value; and
reestablish the receiver of the unacknowledged mode messages in accordance with the initialization value.

Abstract
An apparatus for providing ciphering problem detection may include a processor. The processor may be configured to receive an unacknowledged mode message, initiate operation of a timer based on receipt of the unacknowledged mode message, re-initiate timer operation in response to each subsequent unacknowledged mode message received prior to expiration of the timer, record a timer expiry event in response to the timer expiring prior to receipt of a subsequent unacknowledged mode message, and indicate a data reception error in response to receipt of the subsequent unacknowledged mode message after recordation of the timer expiry event.
