Abstract:
1. A network connection method of a mobile station, the method comprising: checking whether a cell change from a first cell to a second cell is detected while waiting for a network connection request message, after an acquisition of a synchronization with a first base station associated with the first cell; determining, if the cell change is detected, whether a synchronization is acquired with a second base station associated with the second cell and whether the network connection request message is detected; initiating, if the network connection request message is detected after the synchronization is acquired with the second base station, a network entry procedure; saving, if the network connection request message is detected before the synchronization is acquired with the second base station, the network connection request message in a buffer; and initiating, if the synchronization is acquired with the second base station after saving the network connection request message, a network entry procedure using the network connection request message saved in the buffer.
