Methods and systems for hfn handling at inter-base station handover in mobile communication networks

Systems and methods for addressing the de-synchronization of the cryptsync between the network and the mobile stations (eNB) that can occur at mobility are addressed. De-synchronization is resolved by forwarding HFN and PDCP Sequence Number(s) from the source eNB to the target eNB. In order to avoid re-use of a crytosync...
