Method and system for increasing frequency assignment in a mobil telecommunication system

DETAILED DESCRIPTION To solve the problem associated with the conventional method, the present invention is intended to provide a method for performing optimization process when a new frequency assignment (FA) is added, wherein a base transceiver station (BTS) generates a channel list including only the new FA and a mobile station receives the channel list including only the new FA, so that the optimization process is completed without the interference from other subscribers trying to access the new FA.
The invention is also intended to provide a system including an operating mobile station assigned to connect a call through only the new FA and perform performing the optimization process for the new FA.
A preferable embodiment of the method according to the present invention includes a plurality base transceiver stations (BTS) and at least one handset for communicating on a plurality of channels by generating a channel list having the information about all serviceable FAs, the method comprising the steps of (a) adding a new FA and recording the information of each sector for the new FA to a program loaded data (PLD); (b) determining whether the new FA is in an acknowledgement mode, and if it is, generating a channel list accordingly to the conventional method, and if not, (c) determining whether the new FA is in an attempt mode, and if it is, determining which channel number is assigned to the new FA by BTS, otherwise, ending the process of initiating the determination; (d) generating a separate channel list for the corresponding FA that are in the acknowledgement mode in accordance with the assigned channel number; (f) performing optimization process to determine whether channel signal quality of said new FA is good or acceptable; and, (g) switching the attempt mode to the acknowledgement mode after the completion of the optimization process.
Other preferable embodiment of the method according to the present invention includes a mobile station for providing a mobile subscriber with communication services, and a BTS having at least one FA to provide the mobile station with communication services, wherein it is possible for the mobile station to receive the communication services via the FAs by generating a channel list having the information about all serviceable FAs including the newly added FA
