Cells A201–A209 and cells B301–B309 are a plurality of cells in the mobile communication network and, in the case of the present embodiment, the mobile station 30 and base station 20 are in a state of DHO (Diversity HandOver) using cell A201 and cell B301. The cells A202–A209 exist as neighbor cells around the cell A201, and the cells B302–B309 as neighbor cells around the cell B301. The names of these cells herein are given for convenience' sake and, for example, if two cells have different names but an identical cell ID, they will be regarded as an identical cell for the system.
Subsequently, a first method for the neighbor cell notifying apparatus 11 to notify the mobile station 30 of the neighbor cell information items will be described with reference to FIG. 2. The cell information extracting part 112 extracts the neighbor cell information items stored in the cell information storage part 120 in accordance with the output from the cell information input part 111 (step S01). Where the information from the cell information input part 111 is one about cell A201 and cell B301, the cell information extracting part 112 outputs to store the information about the cells A201–A209 and about the cells B301–B309 as neighbor cell information items in the table format as shown in FIGS. 3A and 3B, into the cell information buffer part 113 (step S02).
Subsequently, a second method for the neighbor cell notifying apparatus 11 to notify the mobile station 30 of the neighbor cell information items will be described with reference to FIG. 5. The cell information extracting part 112 extracts the neighbor cell information items stored in the cell information storage part 120, according to the output from the cell information input part 111 (step S11). Where the information from the cell information input part 111 is one about the cells A201 and B301, it outputs to store the information about the cells A201–A209 and about the cells B301–B309 as neighbor cell information items in the table format as shown in FIGS. 6A and 6B, into the cell information buffer part 113 (step S12).
In the second method, each cell is given a priority. In the example of FIGS. 6A and 6B, the cell A201 is given the priority of “1,” and the cell A202 the priority of “2;” this indicates that the priority of cell A201 is higher than that of cell A202. For determining the priorities, high priorities can be given to cells with statistically high handover rates from a cell of interest or to cells with relatively large number of mounted channels.
Subsequently, a third method for the neighbor cell notifying apparatus 11 to notify the mobile station 30 of the neighbor cell information items will be described with reference to FIG. 8. The cell information extracting part 112 extracts the neighbor cell information items stored in the cell information storage part 120, according to the output from the cell information input part 111 (step S21). Where the information from the cell information input part 111 is one about the cells A201 and B301, the cell information extracting part 112 outputs to store the information about the cells A201–A209 and about the cells B301–B309 as neighbor cell information items in the table format as shown in FIGS. 6A and 6B, into the cell information buffer part 113 (step S22). In the third method, each cell is given a priority, just as in the case of the second method.
