Abstract
A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble transmitted by the terminal. A first type of random access preamble is selectable by the terminal from a set of random access preambles, and a second type of random access preamble is directly allocated to the terminal by the network. The network responds with a random access response. The terminal performs a discontinuous reception (DRX) operation that allows it to monitor a downlink control channel discontinuously. The DRX operation includes an active time period during which the terminal monitors the control channel after successful reception of the random access response for the second type of random access preamble until a transmission from the network addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) associated with the terminal is received.
