Patent ID: 8917693

Claim:
A method for communicating messages at a user equipment (UE) in a Long Term Evolution (LTE) mobile communication system, the method comprising: receiving a paging message including information for identifying the UE from a base station; transmitting a physical random access channel (PRACH) preamble to the base station after receiving the paging message; receiving a PRACH preamble response message from the base station through a downlink shared channel (DL_SCH); transmitting a connection request message for requesting a connection to the base station through an uplink shared channel (UL_SCH); and receiving a connection response message in response to the connection request message through the DL_SCH from the base station, wherein the PRACH preamble response message includes an identifier identifying the UE, wherein the identifier included in the PRACH preamble response message is used by the UE to transmit the connection request message to the base station, and wherein the information for identifying the UE included in the paging message is different from the identifier included in the PRACH preamble response message.
