摘要： The present invention relates to an apparatus and method for performing a handoff in wireless communication system. The method includes the steps of establishing communication between a mobile subscriber and a serving cell, determining whether a target cell and the serving cell are collocated, sending a normal burst handoff command to a mobile subscriber, sending a normal burst from the mobile subscriber to the target cell including a time offset, and establishing communication between the mobile subscriber and the target cell. The apparatus relates to a wireless system including a serving cell and a target cell in communication with a mobile subscriber. The mobile subscriber is sent a normal burst handoff, including an instruction to the mobile subscriber to transmit in normal bursts and to main current alignment, when the target cell overlaps the serving cell.

摘要： Each cell has an assigned classification that determines its inclusion in a measurement list for handing off. The candidate cells, which are selected from the measurement list are given priority level assignments. The priority levels are implemented by the candidate neighboring cells measured RF signal strength; and the order of handing off is arranged in accordance with the adjusted RF signal strength.

摘要： A method and system for handing off an on-going communication from a serving cell to a neighboring cell of a cellular communication system having mobile units with a scanning capability. A dynamic threshold is calculated for effecting the handoff under certain operating criteria. The minimum attenuation level of the mobile unit and the minimum level permitted by a neighboring cell is used in selecting the dynamic threshold.

摘要： A method and system for selecting the best handoff candidate cell at times when the number of neighboring cells that meet the measurement criteria is greater than twelve a measurement list is generated. The cells are assigned a handoff measurement priority wherein a handoff priority of zero is assigned to 12-N cells where N is between 1 and 6. A priority of 8 is assigned to the worst N cells. A new measurement list is generated using the 12-N cells and other unreported cells having a higher priority than the N worst cells.

摘要： A mechanism for handing off between an overlay cell (48) and an underlay cell (50). The underlay cell (50) is smaller than and has a common area with the overlay cell. A threshold level (RSSI-THP) is established which corresponds to the sum of a nominal threshold level (RSSI-U) and a value obtained by subtracting the current attenuation level (MT) from the minimum attenuation level permitted by the underlay cell (MU). If the RF signal level of the serving cell (RSSI-SRV) is greater than the established threshold level (RSSI-THP), the mobile unit is handed off to the underlay cell (50), if not already in that cell; and handed off to the overlay cell (48) if equal to or less than the established threshold level (RSSI-THP), if not already in that cell.
