73d42fac71 lte: Discard packets arriving after UE context removal at EpcEnbApplication 
Due to RLF the UE context deletion might get triggered during the reception of a packet by EpcEnbApplication from EpcSgwApplication. This patch will enable  EpcEnbApplication  to discard  such packets.

7ba7fd64dc lte: Avoid checking for connection established in RrcConnectionEstablishmentErrorTestCase 
After the RLF implementation, the UE state upon jumping at a far away location will not be in connected state anymore, thus, we should only check for not connected state.

7284b3ab4d lte: Add TxFailParam in RachConfigCommon 
This patch adds TxFailParam in RachConfigCommon, which enables the eNB to indicate how many times T300 timer can expire at the UE. Upon reaching this count, the UE aborts the connection establishment, and performs the cell selection again. See TS 36.331 5.3.3.6.

643192fd07 lte: Do not generate CQI reports & UE measurements if the UE is not in synch with any cell 
We do not generate the CQI report when the UE is not synchronized to any cell. Also, the RLF is detected after the DL CTRL is received by the UE,therefore, we do not need to generate the CQI reports and the UE measurements for a CTRL for which the RLF has been detected.

57160aa7e2 lte: Allocate non-contention based preamble only if its free 
The non-contention preamble assigned to UE during handover or PDCCH order is valid only until the time duration of the “expiryTime” of the preamble is reached. This timer value is only maintained at the eNodeB and the UE has no way of knowing if this timer has expired. If the UE tries to send the preamble again after the expiryTime and the preamble is re-assigned to another UE, it results in errors. This has been solved by re-assigning the preamble to another UE only if it is not being used (An UE can be using the preamble even after the expiryTime duration).
