摘要： The present invention provides a method of determining handoff parameters. One embodiment of the method includes determining values of a hysteresis for a handoff from a serving cell, one or more pairwise offset values for hand off between the serving cell and one or more neighbor cells, and one or more times-to-trigger (TTTs) for hand off between the serving cell and the neighbor cell(s). The values may be determined So that hand off is triggered beyond a first distance from the serving cell selected to avoid ping-ponging and within a second distance from the serving cell selected so that a mobile unit moving at a selected velocity does not travel beyond a third distance within the TTT.

摘要： The present invention provides a method of assigning cell identifiers to a plurality of cells. The method includes detecting cells within a selected distance from a first cell in the plurality of cells. The distance is selected to encompass portions of neighbor cells of the first cell and neighbor-of-neighbor cells of the first cell. The method also includes assigning a first cell identifier to the first cell. The first cell identifier is different than cell identifiers assigned to the cells detected within the selected distance from the first cell.

摘要： The present invention relates to a method for discovering neighbor cells (NC) in a radio cellular network (NTW) comprising cells, each served by a controller (e NB), the method comprising, with respect to a controller (eNB) serving a cell (C): (a): selecting a frequency (f) in a frequency list, each frequency being associated with a priority (Prio), a target value (TV) and a counter (Count), and wherein said frequency (f) is selected in the frequency list according to its priority (Prio); (b): selecting a terminal (UE) located in the cell (C) and connected with the controller (e NB); (c): sending a control message to the selected terminal (UE), said control message comprising a request to perform radio measurements relating to neighbor cells (NC) of the cell (C), for the selected frequency (f); (d): incrementing the counter (Count) associated with the frequency (f); (e): if the counter (Count) is equal to the target value (TV) for the selected frequency (f), then deleting the selected frequency (f) from the frequency list; repeating steps (a), (b), (c), (d) and (e) during a predetermined time (Tc) or until the frequency list if empty.
