摘要:
A cellular system transfers a call from a source base station to the target base station. A mobile unit measures the strength of pilot signals emanating from surrounding base stations. In response to the result of the measurement, a different frequency hand off operation is initiated by the mobile unit when all pilot signals are lower than a threshold or is initiated by a system controller with consideration being given to the frequency band occupation state of surrounding base stations and the strength information reported from the mobile unit. In a handoff operation, the mobile unit reduces a maximum data rate to modulate user information with a current used frequency and to modulate a different frequency preposition code with a primary frequency so that neighboring base stations may measure the intensity of the preposition code and the system controller can determine how the different frequency hand-off should be operated.

A method for shedding traffic load in a code division multiple access mobile communication system, the method performing a soft handoff operation using the ratio of the received forward link pilot signal power to the sum of all interference signals power to transfer a portion of traffic load in the present serving cell with a high traffic density to an adjacent cell with a low traffic density. When the amount of traffic load in the present serving cell is increased and thus exceeds a link capacity of the present serving cell, handoff parameters of all mobile stations in the present serving cell can be updated on the basis of a power allocation state managed by a base station without reducing the coverage of a forward link. On the basis of the updated handoff parameters, the soft handoff operation is performed from a part of the mobile stations in the present serving cell with the high traffic density (for example, mobile stations at the edge of the present serving cell) to the adjacent cell with the low traffic density. Therefore, the excessive traffic load amount in the present serving cell can effectively be shed.
