Patent ID: 8265643

Claim:
An apparatus for avoiding a collision of a preamble in a network, the apparatus comprising: a neighboring cell identifier to collect neighboring cell information in order to determine whether a neighboring cell exists, and in order to identify the neighboring cell, wherein the neighboring cell identifier receives the neighboring cell information from a terminal within a cell coverage of a corresponding base station or a peripheral device; a parameter collector to collect a code parameter, a time parameter, and a frequency parameter that are used in a preamble of the neighboring cell; and a parameter setting unit to set at least one of a code parameter, a time parameter, and a frequency parameter that are used in a preamble of the base station to be different from the code parameter, the time parameter, and the frequency parameter that are used in the preamble of the neighboring cell, when setting the code parameter, the time parameter, and the frequency parameter that are used in the preamble of the base station, wherein a parameter setting process is performed for a newly installed base station so that the code parameter, the time parameter, and the frequency parameter used in the preamble of the newly installed base station are set to be different than the code parameter, the time parameter, and the frequency parameter used in the preamble of a neighboring cell, wherein the parameter collector requests the code parameter, the time parameter, and the frequency parameter that are used in the preamble of the neighboring cell, to a parameter administration controller based on the neighboring cell information, and receives, from the parameter administration controller, the code parameter, the time parameter, and the frequency parameter that are used in the preamble of the neighboring cell.
