Soft handover method for multicast multimedia broadcasting service in code division multiple access mobile communication system

摘要

The method includes transmitting from a first node B to a unit RNC a first difference between the emission starting point of a first raster of the system from this first node B among the neighboring nodes B and a starting point of receiving a second raster of the system corresponding to the first raster of the system, received from the second node B among the neighboring nodes B. The next step includes transmitting from the second node B to the unit RNC a second difference between the point of start of emission of the second raster of system from the second node B and point of start of reception of the first raster of the corresponding system to the second raster of the system received from the first node B. The next step includes calculating a difference between the emission start points of the first and second rasters of the system from the first and second difference, and informing the first and second nodes B of the point of start of emission of the raster of diffusion data, based on the difference.
