Embodiment Construction

[0060] The present invention provides methods and apparatus for solving handovers with particular neighbor cells. In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0061] image 3 It is a principle flow chart for realizing the difference judgment method of the present invention. Figure 4 for in figure 2 Realized in the community image 3 A flowchart of an embodiment of the method. First, after receiving the measurement report, the RNC checks the original cell and the target cell. Search for differentiated handover decision strategies. If the target cell is a common cell, handover is performed according to the usual rules. If the target cell is a special cell, handover is performed according to predetermined rules. This is the handover condition of the differentiated handover decision strategy in the figure. If the...
