Patent ID: RE40518

Claim:
A method for performing channel assignment in a base station for a mobile communication system, comprising the steps of: generating, in a base station transceiver system (BTS), a connect message upon receipt of a request for assigning a channel to a mobile station, said connect message including channel information indicating a Walsh code, out of 256 Walsh codes, to be used for a channel to be assigned to the mobile station, and a quasi-orthogonal function (QOF) index; transmitting the generated connect message to a base station controller (BSC); generating, in the BSC, a connect ACK (acknowledge) message for acknowledging channel assignment-related information included in the connect message; transmitting the generated connect ACK message to the BTS; and assigning, in the BTS, a channel to the mobile station, said channel having been acknowledged by the BSC, upon receipt of the connect ACK message.
