First Claim
Patent Images
1. A method of transmitting access information in a mobile communications system, the method comprising:
- deciding to perform a handover for a terminal to a cell of a target base station;
transmitting, to the target base station, a handover request for performing a handover from a source base station to the target base station; and
receiving access information from the target base station that received the handover request, wherein the access information is then transmitted to the terminal to access the target base station.

Abstract
In a wireless mobile communications system, a method of transmitting and receiving radio access information that allows a faster and an efficient way of establishing a radio connection between a terminal and a target base station while performing a handover for the terminal to a cell of the target base station. The network transmits in advance, the radio access information and the like, to the terminal so that the terminal can be connected with the target cell in a faster manner which minimizes the total time for the handover process.
