Abstract:
1. A method for handoff between cells, the method comprising: obtaining a cell individual offset for an adjacent cell of an active set cell, wherein the cell individual offset is configured by a network controller based on an adjacent relationship between the active set cell and the adjacent cell; measuring the active set cell and the adjacent cell to obtain a cell measurement; evaluating the cell measurement according to a result of the cell measurement and the cell individual offset, wherein when, during a time period ΔT of measurement report triggering, a pilot signal quality of a target cell in the active set fulfills a condition for removing a cell, the target cell is removed from the active set of a terminal, or when, during the time period ΔT of measurement report triggering, the pilot signal quality of the target cell in a monitored set fulfills a condition for replacing a cell and the active set is full, a worst cell in a cell list of the active set of the terminal is replaced with the target cell in the monitored set; submitting a measurement report to the network controller according to a result of the evaluating; and receiving an instruction, from the network controller, to perform handoff, wherein the instruction is made by the network controller according to the measurement report.
