Abstract: PURPOSE: A method for transmitting upward data at a media access control layer of an asynchronous mobile communication terminal is provided to simplify a data transmission process among a PHY layer, an MAC layer, and an RLC layer. CONSTITUTION: An MAC(Media Access Channel) layer receives a MAC setup request primitive(CMAC-CONFIG-REQ) from an RRC(Radio Resource Control) layer(500). The size of data transmittable to a radio bearer corresponding to a set DCH(Data Channel) parameter is initialized as the maximum TF(Transport Format)(501). If the MAC layer receives a transmission synchronization command primitive(TRC-SYNC-CMD) from a PHY(Physical) layer, the size of data transmittable to all radio bearers corresponding to the corresponding transmission channel is set up to transmit data to an RLC(Radio Link Control) layer through an MAC status indicator(MAC-STATUS-IND)(502-504). The MAC layer sets up the size of the TF not exceeding RLC data length as the size of data transmittable to the next TTI(Transmission Time Interval) to the radio bearer received an MAC status response primitive(MAC-STATUS-RES) from the RLC layer(506). The MAC layer returns to wait TRC-SYNC-CMD(507). To the radio bearer received MAC data request primitive(MAC-DATA-REQ) from the RLC layer, an MAC header is added to configure protocol data units and selects a TFI(Transport Format Indicator) fitting to the RLC data length to send physical data request primitive(PHY-DATA-REQ) to the PHY layer(508-510). A TF not exceeding RLC buffer size is sets as the size of the data transmittable to the next TTI(511).

Abstract: PURPOSE: A signal message comparing system in a software conformance testing for a mobile terminal of an IMT-2000 asynchronous method is provided to reduce a load for message comparison and decoding by determining whether a message exchange procedure is normal by using only a signal message of a lower layer and decoding only an error-generated message. CONSTITUTION: A message receiver(50) receives a layer 3 signal message from a mobile terminal. A message manager(60) generates a comparison signal message of the same expression format as the layer 3 signal message by a user. A message judging unit(70) reads the comparison signal message and the layer 3 signal message and compares them with each other, and judges whether a message exchange procedure is in a normal/abnormal state. A message decider(80) decodes the layer 3 signal message and the comparison signal message if they are judged not to be the same. A message information factor comparator(90) compares the two messages by the unit of information factor to check whether there is an error. A screen output unit(95) outputs an information factor on a screen whenever an error occurs in the message information factor comparator(90). The message manager(60) includes a message database(65) for storing the comparison signal message generated by the user in a file format.
