Abstract

A data communication method in a wireless communication system comprises receiving, from a lower layer (i.e. a Radio Link Control (RLC) layer), a data unit having a sequence number and storing the data unit in a buffer, determining whether the sequence number of the data unit is equal to a sequence number + 1 of a last delivered data unit and, based thereupon, delivering in ascending order all stored data units with consecutively associated sequence numbers greater than or equal to the sequence number of the received data unit. Specifically, the invention provides a method of immediately delivering continuously and/or consecutively received Packet Data Convergence Protocol (PDCP) Service Data Units (SDUs) to an upper layer if a PDCP entity receives the PDCP SDUs during a process of RLC re- establishment within an Evolved Universal Mobile Telecommunications System (E-UMTS).
