Abstract: A method and system for handling security synchronization for prolonged periods of no-reception of voice frames. The method includes receiving one or more protocol data units (PDUs) by a radio link control (RLC) sub layer and determining a time period between the receiving of each PDU and a previously received PDU by the RLC sub layer. Further, the method includes initiating recovery procedure for the time period exceeding a first predefined time. The recovery procedure includes identifying count of the one or more PDUs to be recovered, deciphering each PDU using a plurality of hyper frame numbers (HFNs) and updating a master HFN based on the deciphering. The master HFN deciphers each PDU among the one or more protocol data units. Further, the method also includes delivering the one or more PDUs to a packet data convergence protocol sub layer where type verification of the PDU is performed.

Abstract: A method for enhancing Layer 2 for High Speed Packet Access uplink. The method includes segmenting a Radio Link Control (RLC) Service Data Unit (SDU) into plurality of Medium Access Control (MAC) i/is Packet Data Units (PDUs), a size of which is limited to a Maximum RLC PDU Size (MRPS) and indicating RLC PDUs of the same size by a single Length (L) entry and indicating the RLC PDUs by a (size, number) pair in the L entry.
