Patent ID: 8600389

Claim:
A method for controlling user equipment's residing in a cell, applied in a communication system including a source cell, a virtual cell, and a target cell, the method comprising: transmitting, by a base station of the virtual cell, a first signal including first common channel information at a first frequency, wherein the first frequency is the same as a frequency of a signal transmitted by a base station of the source cell, the first frequency is different from a frequency of a signal transmitted by a base station of the target cell, and a scrambling code of the first signal is different from a scrambling code of the signal transmitted by the base station of the source cell; and the first common channel information at least comprises a pilot of the virtual cell, a location area code, and inter-frequency reselection threshold, so that the user equipment performs intra-frequency cell reselection according to the pilot in the first common channel information until the virtual cell is reselected, and so that the user equipment performs inter-frequency cell reselection according to the inter-frequency reselection threshold in the first common channel information until the target cell is reselected if the user equipment determines that the location area code is the same as a location area code of the source cell and a location area code of the target cell.
