摘要
A method for establishing a new broadcast control channel carrier frequency within a cell without disturbing ongoing call traffic is disclosed. A cell having a base station transmitting broadcast control channel data over an existing BCCH carrier frequency establishes a second BCCH carrier frequency within the cell. During a first time period BCCH data is transmitted on the existing first BCCH carrier frequency. During a second time period, both the existing and new BCCH carrier frequencies carry BCCH data to enable surrounding mobile stations to detect and recognize both carriers. The transmission of the old BCCH carrier frequency is then discontinued during a third time period, such that the broadcast control channel data is only transmitted on the new BCCH carrier frequency.
